Infant car seat stroller

[0002] The present invention relates to a child's stroller and more particularly to a child's stroller having a convenient frame latch mechanism and pivoting bolster member with activity tray operative for transporting an infant carrier/car seat in the stroller.

[0003] Child stroller frames that are configurable between folded and deployed positions by manual activation of a frame latching device are well known. One type of foldable, four-wheel stroller frame has a pair of front legs coupled to the stroller handlebar through a latching device operative for locking the handlebar and front leg in a parallel relation when the stroller is in a deployed or use configuration, and a pair of rear legs rotationally coupled to either the front legs or handlebar. One example of this variety of stroller is found in U.S. Pat. No. 5,388,853. Latching mechanisms for stroller frames are usually designed with a view towards providing users with a convenient means for folding and unfolding a stroller while at the same time providing a reliable locking mechanism which reduces the possibility that the stroller frame will collapse during use by sudden disengagement of the latching mechanism.

[0004] There are a wide variety of latch mechanisms known in the art. One such latch is described in U.S. Pat. No. 5,605,409 (Haut). Haut describes a latch consisting of a first leg rotationally coupled to a first arm of a stroller frame through a body member with a spring-biased locking device being provided on the first arm for locking the first leg and first arm in a parallel relationship when the stroller is in an operating position. The locking device consists of a catch movable against a compressed spring to allow the first leg to be rotated relative to the first arm when configuring the stroller in a collapsed configuration. To fold the stroller, the catch is manually pulled upwards against the spring force to allow a user to then rotate the first arm downwards. Haut's latching device is disadvantageous since the first arm (which corresponds to the stroller handle bar) must be simultaneously rotated while the user is holding the catch open, often times from the rather awkward rearward stroller position (i.e., rearward of the handle bar), thereby requiring the user to lift up on the stroller and/or reach over the handlebar to begin the folding sequence. It would be preferable if the latching device were such as to allow a user to release the latch and fold the stroller in one simple motion from a convenient position.

[0005] Another example of a stroller latch device requiring a two-step folding sequence is found in U.S. Pat. No. 5,388,853 (Lauro). Lauro's locking member includes a sleeve coaxial with a second tube for rotatably and slidably mounting the locking member on the second tube. The locking member is rotated around the second tube so that a receptacle portion of the locking member may be brought into engagement with the first tube to lock the first and second tubes in a parallel relation. Lauro suffers from the same drawback of requiring the user to first unlock the latch and then fold the stroller. Lauro suffers from the additional drawback of not providing a latch which self-locks as the stroller is deployed in a use configuration. The self-locking feature is important as it reduces the possibility that a child will be placed in the stroller before properly engaging the latch.

[0006] Still another variety of a stroller latch is found in U.S. Pat. No. 5,427,402 (Huang '402) and U.S. Pat. No. 5,460,398 (Huang '398). Huang '398 describes a latch consisting of a positioning means secured to a front member and pivotally coupled to a lower end of the stroller handlebar and a retainer means fixed to the handlebar and including a retainer member adapted for engagement with a spring-loaded sliding hook member mounted to the positioning member. To disengage the latch, a button operative for displacing the sliding hook member is depressed to release the retainer member, thereby allowing the handle to be rotated relative to the front member. Huang '402 describes a similar latch approach providing a spring loaded button for releasably fixing a positioning and retaining seat in a locked configuration. The latches described in Huang '398 and Huang '402 are undesirable due to the complexity of the button engagement mechanisms. It would be preferable if the number of moving parts in the stroller latch were reduced and/or if the mechanism for locking and unlocking the stroller were simplified to promote durability of the latch and reduce costs associated with manufacture of the latch. Huang '398 and Huang '402 also do not satisfactorily address the need for providing a more convenient means for folding and unfolding a stroller.

[0007] In light of the drawbacks and limitations described and shown in existing stroller latches, there is a need for a stroller latch which provides a more convenient means folding and unfolding a stroller. In particular, the known stroller latches suffer from one or more of the following drawbacks: the stroller folding sequence requires a two step process (either carried on simultaneously or as separate steps) of first disengaging a latch and then folding the stroller; the latch device is unnecessarily complicated, involving an excessive number of moving parts; or the latch operation and folding of the stroller is unnecessarily complicated.

[0008] It has been found to be very convenient for parents to be able to transport infants to and from strollers by providing a mounting device on the stroller for securing handheld infant carriers and/or infant car seats directly to the stroller frame. By providing a means for mounting the infant carrier/car seat to the stroller, the parent can more easily transport the infant from one place to another and a resting infant will not be as disturbed during travel. It has also been found desirable to provide a stroller safety bar or front tray section for a child seated in a stroller.

[0009] One example of a stroller which is operative for mounting an infant carrier is described in U.S. Pat. No. 5,727,798 (Walters). Walters' stroller includes a U-shaped safety bar having free ends coupled to the lower tubes of the frame. The U-shaped safety bar includes a recess at its center for releasably receiving an infant carrier having an operator controlled latch and recesses formed in the infant carrier shell for receiving the safety bar. Walters approach for mounting the infant carrier is undesirable in that the U-shaped bar coupled to the lower tube is limited to fixed bars disposed across the seating area. It would be preferred if an infant carrier mount could be provided that is re-positionable for removal/placement of a child in the stroller seat, functions as an activity tray, and which allows a toddler to climb in and out of the stroller seat without being obstructed by the infant carrier mount or activity tray.

[0010] Another approach for mounting an infant carrier to a stroller is found in the “Infant Safety Seat/Carrier and Travel System” by Graco Children's Products, Inc. (Graco). Graco is similar to Walters with the exception that Graco's infant t carrier mounts to a removable tray disposed across the stroller seating area, rather than the U-shaped safety bar as in Walters. Graco describes an infant carrier/stroller combination in which the infant carrier mount to the stroller also serves as a tray that may be selectively removed or pivoted away from the seating area. The Graco tray includes a center recess where the infant carrier is latched (as in Walters) and a pair of ends having flexible collars for gripping the upper ends of the left and right front leg tubes. The tray may be pivoted about one of the right and left leg tubes by prying a collar to allow the tray to be pivoted about the other leg tube (the tray may also be completely removed by prying open both left and right collars). Graco's stroller tray/infant carrier mounting scheme is undesirable because care must be used to insure that the left and right collars are secured to the leg tubes before the infant carrier is mounted and the tray must be completely removed if a parent does not wish to have a tray disposed across the seating area during use. It would be preferred if a tray that also serves as an infant carrier mount were available which reduced the possibility that the infant carrier would be mounted on the tray which was not safely secured to the stroller frame and which also could be conveniently relocated on the stroller without having to completely remove the tray from the stroller.

[0011] In light of the drawbacks and limitations described and shown in existing infant carrier/stroller systems, there is a need for a stroller operative for mounting an infant carrier which overcomes the drawbacks and limitations of the existing art. In particular, the known stroller/infant carrier mounting approaches suffer from one or more of the following drawbacks: the infant carrier is mounted to a fixed bar extending across the seating area; or the stroller provides a infant carrier mount/tray which is not easily re-positionable on the stroller to accommodate different uses.

[0012] The invention satisfies the above identified needs in stroller latches while avoiding the problems and disadvantages of the existing art by providing a convenient latching mechanism that is self locking and which is disengaged to fold the stroller by pivoting latch handles to simultaneously disengage the latch and fold the stroller frame. The invention also satisfies the above identified needs in infant carrier/stroller systems while avoiding the problems and disadvantages of the existing art by providing a stroller bolster having a tray area and child carrier mount for mounting a child carrier, the bolster being rotationally coupled to the upper ends of the stroller handlebar for convenient repositioning of the stroller tray area and child carrier mount by pivoting the bolster between a stowed position and a use position whereby the bolster tray and child carrier mount are placed across the stroller seating area. By providing a re-positionable bolster pivotally coupled to the stroller handlebar, the stroller provides convenient removal/placement of a child in the stroller, allows a child to climb in and out of the stroller without being obstructed by the tray or child carrier mount, and allows the bolster to be pivoted between the use and stowed positions while children of varying seated heights are seated in the stroller.

[0013] In one aspect of the invention, a stroller latch for selectively configuring a stroller frame between a folded and unfolded positions includes a latch mount pivotally mounted to the lower end of a stroller handle and fixedly mounted to the upper end of the stroller front leg, a collar slidably coupled to the stroller handle, the collar including a locking sleeve releasably engageable over the upper end of the front leg to lock the front leg and stroller handle in a deployed position, and a latch handle pivotally coupled to the latch mount and operative for releasing the locking sleeve from the upper end of the front leg and configuring the stroller in the folded position by pivoting the latch handle into mating engagement with the collar. Preferably, the locking sleeve is released by rolling surface contact between a first engagement surface of the collar and a second engagement surface of the latch handle to impart upward motion for releasing the locking sleeve. The latch handle preferably includes a downwardly extending hand grip to enable a user facing the rear of the stroller frame to fold the stroller by lifting up on the hand grip, thereby rotating the latch handle to configure the stroller in the folded position.

[0014] In another aspect of the invention, there is provided a stroller frame including a stroller handle, rear leg and front leg, the stroller handle being pivotal about a rotation axis and the stroller being folded by rotating the stroller handle in a stroller folding direction. A first latch member is slidable along the lower end of the stroller handle, the first latch member including a locking sleeve received over the upper end of the front leg, thereby locking the stroller frame in the deployed position, and a second latch member is pivotally coupled to the front leg hinge for pivotal motion about the axis of rotation. In this aspect of the invention, the stroller frame is configured from the deployed to the folded position by pivoting the second latch member in the stroller folding direction.

[0015] In still another aspect of the invention, a stroller latch is adapted for selectively configuring a stroller frame between a folded and unfolded position, the stroller frame including a stroller handle having a lower end, front leg having an upper end and a rear leg hingedly coupled to the stroller handle through a rear leg hinge. In this aspect of the invention, the stroller latch includes a latch mount pivotally mounted to the lower end of the stroller handle and fixedly mounted to the upper end of the front leg, a locking member coupled to the stroller handle, the locking member being releasably engageable with the upper end of the front leg to configure the stroller frame in the unfolded position, an engaging surface formed on the locking member, and a cam defining a camming surface disposed in operative proximity to the engaging surface, the cam being pivotally coupled to the latch mount and operable for configuring the stroller in the folded position by pivoting the camming surface into mating engagement with the engaging surface.

[0016] In still another aspect of the invention, a stroller adapted for mounting an infant carrier or car seat is provided. The stroller includes a stroller bolster having left and right terminal ends pivotally coupled to said stroller handle at the left and right intermediate ends thereof and a center section positionable between a first position wherein the center section is positioned across the seating area and a second position wherein the center section is positioned adjacent the stroller handle upper end. The center portion includes a child activity area including left and right end portions and a center portion extending between and forward of the left and right end portions, a child carrier mount for mounting a child carrier, the child carrier mount including left and right mounting members disposed rearward of the center portion and extending inward from the respective left and right end portions, wherein the left and right mounting members are adapted for receiving corresponding latching hooks of an infant carrier.

[0028] Reference will now be made to the presently preferred embodiment of the invention, examples of which are illustrated in the appended drawings and the following detailed description.

[0029] Referring to FIGS. 1 and 2, the preferred embodiment of the stroller incorporating the principles of invention includes a stroller frame 300 configurable between deployed and collapsed positions by manual operation of a right and left frame latch 400a, 400b, soft goods secured to frame 300 which form a seating area 380 for a child occupant and a bolster 500 pivotally mounted to frame 300 and positionable across seating area 380 (FIG. 1) or adjacent to an upper end 304 of stroller handle 302 (stowed position, FIG. 2). Seating area 380 includes an adjustable backrest 382 and seat 384. Referring briefly to FIG. 10, the stroller is adapted for mounting an infant carrier 30 on bolster 500 so as to enable safe transport of a young child in the stroller without removing the child from infant carrier 30.

[0030] Reference will now be made in detail to stroller frame 300 and latch 400. As shown in FIG. 2, frame 300 includes a U-shaped handle 302 having an upper end 304 and left and right downwardly extending terminal ends 308a, 308b, a pair of left and right rear legs 320a, 320beach having a lower end 322 mounting a stroller wheel 324 and an upper end 326 pivotally coupled to handle 302 through a rear leg hinge 328 (as best seen in FIG. 3), a pair of left and right front legs 330a, 330beach having a lower end 332 mounting a stroller wheel 334 and an upper end 336 coupled to handle 302 through latch 400 (as best seen in FIG. 3), a frame brace 338 extending between and fixedly connected to left and right front legs 330a, 330band U-shaped pivot member 340 extending between and pivotally connecting left and right front legs 330a, 330bto left and right rear legs 320a, 320b. Handle 302, rear legs 320aand 320b, front legs 330aand 330b, first frame brace 338 and pivot member 340 are preferably made from hollow metal tubing.

[0031] Left and right latches 400a, 400bare preferably of the same construction and operate in the same manner. Therefore, only left latch 400awill be described in detail with the understanding that the same description applies equally to right latch 400b. Latches 400a, 400bare preferably made from molded plastic.

[0032] Referring to FIGS. 3, 4a, 4b, 5, 6aand 6b, latch 400aincludes a collar 410, a latch mount 450 and a latch handle 480, each of which are preferably formed from molded plastic. Referring to FIGS. 3, 4a-4b, collar 410 includes a top end 412 having a generally forward sloping surface 414, bottom end 416 defining a planar mating surface 418 with latch mount 450 and a rearward end 420 defining a cavity 424 extending from top end 412 to bottom end 416, the inner wall spacing of which being sized to allow collar 410 to freely slide along the longitudinal axis of stroller handle 302 upon insertion of terminal end 308ainto cavity 424. Referring to FIG. 3, collar 410 is preferably spring biased towards latch mount 450 to ensure that locking sleeve 438 (discussed below) does not release from top portion 337 of front leg 330aduring use and to provide a self-locking feature when configuring stroller frame 300 from folded to deployed positions, as discussed later. The spring biasing mechanism for collar 410 is constructed as follows: a longitudinal slot or channel 310 is formed in collar 410 to permit travel of block 312 (which is secured to handle 302 by a rivet) within longitudinal channel 310 as collar 410 is moved along stroller handle 302. A compression spring 314 (i.e., a spring that resists outward extension of its ends) is then secured at one end to collar 410 and at the other end to block 312. Thus, any upwards motion of collar 410 along handle 302 is resisted by spring 314.

[0033] Referring to FIG. 4b, a locking sleeve 438 is formed near forward end 426 and is sized to receive a top portion 337 of front leg upper end 336. When top portion 337 is received in locking sleeve 438, front leg 330ais prevented from rotating relative to stroller handle 302, thereby locking stroller frame 300 in the deployed position, FIG. 3. Locking sleeve 438 extends upward from bottom end 416 a sufficient height so as to fully capture top portion 337 and bring collar planar mating surface 418 into mating contact with latch mount 450 mating surface 454. Formed on the left side 428a(FIG. 4a) and right side 428b(FIG. 4b) of collar 410, near forward end 426, are left and right first engagement surfaces 432a, 432bpositioned for engagement with corresponding left and right second engagement surfaces 490a, 490bof latch handle 480 when latch handle 480 is pivoted upwards to disengage latch 400aand configure stroller frame 300 in the folded position, as discussed in greater detail below.

[0034] Referring to FIGS. 3, 6aand 6b, latch mount 450 includes a forward end 458 and a rearward end 460 defined by a pair of rearwardly extending left and right walls 462a, 462b. A hole 468 extends from top to bottom through latch mount 450 and receives upper end 336 of front leg 330a, FIG. 3. Upper end 336 is extended through hole 468 such that top portion 337 extends out beyond a top end 452 of latch mount 450, thereby allowing top portion 337 to be received in locking sleeve 438, as discussed above. Upper end 336 is fixed in hole 468 by any conventional means known in the art, e.g., riveting upper end 336 to latch mount 450. Top end 452 of latch mount 450 defines a mating surface 454 which mates with collar mating surface 418 when top portion 337 of front leg 330ais inserted into locking sleeve 438. Terminal end 308aof handle 302 is pivotally coupled to latch mount 450 at rearward end 460 by passing a pivot pin 316 through terminal end 308aof handle 302 with the ends of pivot pin 316 being supported in left and right bearing holes 472 formed in the respective left and right walls 462a, 462bof latch mount 450. Rearward end 460 is formed with an exposed end so as to allow handle 302 to rotate approximately 180 degrees when stroller frame 300 is configured between deployed and folded positions, as can be seen by comparing FIG. 3 with FIG. 7d.

[0035] Referring to FIGS. 3 and 5, latch handle 480 includes a pair of left and right arms 484a, 484b, a hand grip 496 extending downward at a right angle from a proximal end of arms 484a, 484bwith the distal ends of arms 484a, 484bextending over the right and left sides of latch mount 450 forward end 458. Left and right latch handle pivot holes 470a, 470bare formed at the distal ends of arms 484a, 484b. Latch handle 480 is pivotally coupled to latch mount 450 by inserting a pivot pin (not shown) through latch mount with the ends of the pivot pin being supported in pivot holes 470a, 470b. As shown in FIG. 3, latch handle 480 rests with hand grip 496 extending downwardly from latch mount 450, lying adjacent to and parallel with front leg 330aso that a user may conveniently operate latch 400afrom a rearward facing position (i.e., adjacent to front legs 330 and facing seating area 380) to facilitate folding of stroller frame 300, as discussed below. The upper surfaces of left and right arms 484a, 484bdefine the previously mentioned left and right second engaging surfaces 490a, 490bfor latch handle 480 which engage first engaging surfaces 432a, 432bof collar 410 when latch handle 480 is pivoted about pivot 470.

[0036] The operation of latches 400a, 400band folding sequence for stroller frame 300 will now be described in detail by reference to the operation of left latch 400aand corresponding folding sequence for left front leg 330a, left rear leg 320aand left terminal end 308aof stroller handle 302 with the understanding that the same description applies to right latch 400b, right rear leg 320b, right front leg 330band right terminal end 308b. Referring to FIG. 7a, stroller frame 300 is locked in a deployed position when locking sleeve 438 is inserted over top portion 337 of front leg 330asuch that front leg 330aand terminal end 308bof stroller handle 302 are secured in a fixed parallel relation. Referring to FIG. 7b, disengagement of latch 400ais initiated by pulling up on hand grip 496 to cause latch handle 480 to pivot upwardly and thereby bring first engagement surfaces 432aand 432bof collar 410 into engagement with second engagement surfaces 490aand 490b, respectively, of latch handle 480. Preferably, collar 410 includes both a right and left first engagement surface 432a, 432bfor engaging left and right second engagement surfaces 490a, 490bof latch handle 480. However, both a right and left pair of engagement surfaces are not necessary. Latch handle 480 may include only a left (or right) second engagement surface 490 for engagement with a corresponding left (or right) first engagement surface 432 of collar 410 without departing from the scope of the invention.

[0037] The detailed description of first and second engagement surfaces 432 and 490, respectively, follows by reference in detail to left engagement surfaces 432a, 490awith the understanding that the same description applies to right engagement surfaces 432band 490b.

[0038] As mentioned earlier, first engagement surface 432aand second engagement surface 490aare brought into contact when stroller frame 300 is to be configured from the deployed to the folded position. As can be seen in FIGS. 7a-7d, second engagement surface 490aand first engagement surface 432adescribe a pair of curved surfaces disposed adjacent to each other. First engagement surface 432aand second engagement surface 490aare provided for the purpose of translating pivotal motion of latch handle 480 into upward motion of collar 410 by rolling surface contact between surfaces 432a, 490aas latch handle 480 is pivoted about pivot 470, as best shown in FIGS. 7band 7c. Thus, the mechanism described by the interaction between collar 410 and latch handle 480 may be thought of as a cam. The upward motion referred to corresponds to the direction of travel of collar 410, which is parallel to the longitudinal axis of stroller handle 302 at lower end 308a. First engagement surface 432aand second engagement surface 490aare preferably formed to approximate an arc of a circle, although the invention is not limited to this embodiment. The preferred embodiment uses a pair of opposing surfaces approximating arcs of a circle since it was found that this particular pair of cooperating surfaces is effective in causing second engagement surface 490ato impart a force to collar 410 that is roughly parallel to the longitudinal axis of stroller handle 302 throughout the range of angular motion of latch handle 480 as it is pivoted about pivot 470. It is contemplated that other cooperating pairs of engagement surfaces will also be effective in translating pivotal motion of latch handle 480 into upward motion of collar 410 without departing from the scope of the invention and that the particular shape of surfaces 432a, 490amay be modified to suit particular needs. Referring to FIGS. 7b, 7cand 7d, the force imparting upward motion to collar 410 causes locking sleeve 438 to be pushed away from top portion 337 of front leg 330a. Once locking sleeve 438 has been displaced a sufficient amount along its direction of travel by latch handle 480, locking sleeve 438 clears top portion 330a, thereby disengaging stroller latch 400a. Stroller handle 302 may then pivot about rear leg 320 to configure stroller frame 300 in a folded position. Once stroller handle 302 has begun to fold over rear leg 320, stroller handle 302 will then naturally continue to rotate about rear leg 320 until stroller handle 302 is in the folded position, FIG. 7d.

[0039] When locking sleeve 438 is clear of top portion 330a, stroller handle 302 can then begin to rotate in the stroller folding direction. That is, stroller handle 302 rotates about rear leg hinge 328 and over rear leg 320aso as to bring upper end 304 of stroller handle 302 into an adjacent relation with lower end 322 of rear leg 320a, thereby configuring stroller frame 300 in the folded position. Thus, in the folded position, rear leg 320ais positioned between stroller handle 302 and front leg 330a, as illustrated in FIG. 7d. As can be seen by inspection of FIGS. 7b-7d, the rotation directions for latch handle 490 and stroller handle 302 are both counterclockwise. This feature is desirable since it provides a convenient means for folding stroller frame 300 since stroller frame 300 will fold in the same direction as the user is pivoting latch handle 480. Thus, stroller frame 300 is configurable from a deployed position where stroller handle 302 and front legs 330aand 330bare locked in a parallel relation to a completely folded position by positioning oneself in the rearward facing direction (i.e., adjacent to front leg 330aand facing seating area 380), grasping hand grips 496 of left and right latches 400a, 400band pivoting latch handles 480a, 480bupwards. To configure stroller frame in the deployed position (FIG. 2), stroller handle 302 is rotated clockwise in FIG. 7d. As stroller handle 302 rotates, each of the top portions 337 of front legs 330a, 330bengage with mating surfaces 418 of collars 410 and ride along mating surfaces 418 until top portions 337 are forced into locking sleeves 438 by action of springs 314 biasing mating surfaces 418 of collars 410 into mating engagement with the corresponding mating surfaces 454 of latch mounts 450. Thus, left and right latches 400a, 400bare self-locking as stroller handle 302 is rotated into a parallel relationship with front legs 330aand 330b.

[0040] Other embodiments of latch 400 are contemplated. For example, latch handles 480 of left and right latches 400aand 400bmay be integrally formed with a tray or grab bar extending across seating area 380. Thus, latch handles 480 may be configured to function as both a support for a tray or grab bar and as a stroller folding handle.

[0041] Reference will now be made in detail to bolster 500 and infant carrier 30. Referring to FIGS. 1, 2, and 8, bolster 500 is generally U-shaped having an activity area 510, left and right arms 502a, 502beach having a terminal end 503 pivotally coupled to stroller handle 302 at an intermediate end 318 thereof, a pair of left and right bolster supports 506a, 506bfor supporting bolster 500 on top surface 414 of collar 410 when bolster 500 is positioned to extend across seating area 380, as shown in FIG. 1, and a mounting section 518 for mounting infant carrier 30 on bolster 500, as illustrated in FIG. 10. The pivotal coupling between terminal end 503 and stroller handle 302 may be accomplished by any well known means in the art. Bolster arms 502a, 502b, and activity area 510 are preferably constructed as a one-piece molded plastic body,

[0042] As mentioned earlier, bolster 500 is positionable adjacent upper end 304 of handle 302 when not in use and can be easily rotated to extend across seating area 380 for a child passenger. By providing a pivoting bolster 500, a parent can easily remove or place a child in seating area 380, attend to a child's needs without being obstructed by a center bar or tray and allow a child to climb in and out of the stroller seat without being obstructed by activity area 510. Moreover, when a parent does not wish to place activity area 510 across seating area 510, bolster 500 can simply be stowed at upper end 304, rather than having to completely remove bolster 500 from stroller frame 300. The U-shape of bolster 500 and the pivot locations for arms 502a, 502ballows a user to pivot bolster 500 between a stowed and use position (i.e., extending across seating area 380) while children of varying seating heights are seated in the stroller.

[0043] Referring to FIG. 8, activity area 510 includes left and right end portions 512a, 512band a center portion 515 extending forwardly and between end portions 512aand 512b. Formed on a top surface 509 of activity area 510 are left and right cup holders 514 and a tray 516.
