Description
Background of the Invention
1. Field of the Invention
This invention relates generally to automobile accessories and more particularly to a storage apparatus for lifting a removable hardtop from an automobile, storing the hardtop in an elevated storage position, and replacing the hardtop on the automobile.
2. Discussion of the Prior Art
There is commercially available a hardtop storage apparatus including a hoist for lifting a removable automobile hardtop from the automobile body to facilitate storage of the hardtop on a special wheeled cart when the top is not being used and for later replacing the hardtop on its automobile body. This commercially available hoist comprises a winch mechanism including an overhead winch having a cable attached to a cross bar which can be lowered to a position over the roof of the hardtop. Depending from the ends of this cross bar are two griping devices for attachment to opposite edges of the hardtop. This hoist is selectively operable to lift the hardtop from and lower the hardtop onto the automobile body. The cart attaches to the cross bar to support the hard top for movement to and from a storage area.
This commercially available hardtop storage apparatus has several disadvantages. Among the foremost of these disadvantages are the following. The hardtop is not covered when stored on the wheeled cart and is therefor subject to the accumulation of dust and other airborne particles, vapor, and the like. Accordingly, use of the storage apparatus necessitates the frequent use of cleaners to clean the hardtop which involves the risk of scratching or otherwise marring the top. The hardtop is stored at ground level. As a consequence, a special area must be set aside for storing not only the hardtop when the top is positioned on the storage cart but also the cart by itself when the hard top is mounted on the automobile. Also, storage of the hardtop at ground level creates the ever present risk of damage to hardtop by a person carrying an object and running into the top or dropping the object on the top. Finally, the available storage apparatus is relatively costly since it requires two separate components, namely, the hoist and the storage cart, and transferring the hardtop from the hoist to the storage cart and from the cart to the hoist requires substantial manual skill and physical strength.
U.S. Pat. No. 4,600,177, dated Jul. 15, 1986, to Fritz and my prior U.S. Pat. No. 5,263,687, dated Nov. 23, 1993, disclose automobile hardtop storage apparatus which avoid at least some of these disadvantages of the commercially available hoist-cart storage system referred to above. These patented hardtop storage apparatus have the common features of a hardtop supporting harness and a hoist for lifting and lowering the harness. The harness includes straps joined to one another at a central support point of the harness and having free ends mounting clips in the form of hooks or plates for releasable attachment to opposite edges of a removable automobile hardtop. The hoist includes an overhead support to be mounted on the ceiling of a garage or the like and a flexible lifting member in the form of a cable or strap attached at one end to the support point of the harness and extending upwardly from the harness, over a roller on the overhead support, to a rotary drum which is rotatable in one direction to lift the harness to an elevated storage position and in the opposite direction to lower the harness to a lowered position. When the harness is in its elevated storage position, an automobile may be driven to and from a parked hardtop transfer position below the harness without contacting the harness or a hardtop supported by the harness. When in its lowered position, the harness is disposed for attachment to and detachment from the removable hardtop of an automobile in the parked hardtop transfer position.
These hardtop storage apparatus are used in the following way. An automobile mounting a removable hardtop is parked in the hardtop transfer position below the elevated harness, after which the hardtop is released for removal from the automobile, the harness is lowered, the harness clips are attached to opposite edges of the hardtop, and the harness is raised to lift the hardtop to an elevated storage position in which the automobile may be driven from and later return to the hardtop transfer position without contacting the elevated hardtop. The hardtop is replaced on the automobile by reversing this procedure.
In addition to the above features which are common to the hardtop storage apparatus of both patents mentioned above, the storage apparatus of my prior U.S. Pat. No. 5,263,687 includes a zippered hardtop dust cover and a pair of pivoted storage supports. The dust cover is attached to the harness and encloses the hardtop when in its elevated storage position. The storage supports are pivotally mounted on the overhead hoist support for movement between retracted positions in which they permit a hardtop to be lifted to and lowered from its elevated storage position and extended positions in which the storage supports are disposed to support a hardtop in its elevated storage position.
Summary of the Invention
This invention provides an improved automobile hardtop storage apparatus. In contrast to the harness and hardtop attachment clip arrangement of the patented hardtop storage apparatus mentioned above, the improved hardtop storage apparatus of this invention has a sling which supports an automobile hardtop with a cradling action without the use of hooks, plates, or other clips attached to the hardtop edges. This sling has a generally central support point attached to a flexible lifting member of a hoist for lifting and lowering the sling. The sling comprises flexible sling members, preferably straps, having ends joined to one another at or close to the sling support point and opposite free ends, and connecting means for releasably joining these free ends of the sling members to one another. The hoist includes an overhead support to be mounted on an overhead structure, such as the ceiling of a garage, and means connecting the support and sling for lifting the sling to an elevated storage position and lowering the sling to a lowered position.
In use, the overhead support of the improved hardtop storage apparatus is secured to the ceiling of a garage or other suitable overhead structure of sufficient height above the underlying floor or other supporting surface to enable an automobile having a removable hardtop to park below the sling of the apparatus when sling occupies it elevated storage position. The hardtop of the parked automobile is released for separation from the automobile body, and spacers, depicted herein as gap pillows, are inserted between the top and the automobile body to provide spaces or gaps between the hardtop and the automobile body.
The hoist is now operated to lower the sling to a lowered position in which the support point of the sling is located just above or rests on the roof of the hardtop approximately in line with the center of gravity of the hardtop. Finally, the free ends of the flexible sling members are extended around and under opposite extremities, preferably the front and rear extremities or ends, of the hardtop and inserted through the gaps between these extremities and the underlying portions of the automobile The free strap ends are now pulled toward one another across the underside of the hardtop and joined to one another to form a completed cradle-like sling for the top. The hoist is then operated to lift the sling and the cradled hardtop to an elevated storage position with the top resting on the joined free end portions of the sling members which extend across the underside of the hardtop. In this elevated storage position, the automobile may be driven from under the hardtop and later returned to its parked position below the elevated hardtop for replacement of the top on the automobile without contacting the elevated top or sling.
The presently preferred hardtop storage apparatus of the invention described herein have a sling comprising a single front strap and two rear straps. The front strap extends forwardly from the sling support point around and under the front end of the cradled hardtop. The two rear straps extend rearwardly from the sling support point around and under the rear end of the hardtop. The free end of the front strap and the free ends of the two rear straps are releasably joined at the under side of the cradled hardtop. The pair of rear sling straps pass through slots in a stabilizing bar which retains these rear straps in proper spaced relation and aids in maintaining the hardtop in a balanced position. These preferred storage apparatus include hinged storage supports like those of my prior U.S. Pat. No. 5,263,687 which support the hardtop in its elevated storage position so as to remove the weight of the hardtop from the hoist. One described embodiment of the invention includes a dust cover which is secured to the sling and encloses the hardtop in its elevated storage position to shield the top against airborne dust and other particles and against damage by contact with an external object. This cover includes a sleeve which receives the stabilizing bar of the hardtop sling.

Description of the Preferred Embodiments
Turning now to these drawings and first to FIGS. 1-8, the illustrated automobile hardtop storage apparatus 20 includes a sling 22 for supporting in cradling fashion the removable hardtop 24 of an automobile 26 and a hoist 28 for lifting and lowering the sling and cradled hardtop between an elevated storage position illustrated in broken lines in FIG. 1 and a lowered position illustrated in full lines in FIG. 1. The hardtop shown is illustrative of commercially available hardtops offered by Mercedes Benz, General Motors (Corvette and Buick) and Chrysler. A typical hardtop weighs about 150 pounds and has opposite front and rear extremities or ends, opposite longitudinal extremities or sides, side walls with side windows along rear portions of the sides, and a rear wall with a rear window at the rear end of the hardtop. When the hardtop 24 is secured in place on the automobile 26, the front extremity or end of the hardtop is supported on and secured to the top of the automobile windshield frame 26a. The rear extremity or end of the hardtop is supported on and secured to a rear portion 26b of the automobile body. The longitudinal extremities or sides of the hardtop are supported on and secured to side portions of the automobile body.
Hoist 28 comprises a support 30 to be mounted on an overhead supporting structure 32 and a winch mechanism 34 on the support including a lifting member 36 attached to the sling 22 at a generally central sling support point 38 for raising and lowering the sling to and from its broken line elevated position of FIG. 1. Sling 22 comprises flexible sling members 40 having normally upper ends 42 which are permanently joined to one another at or close to the sling support point 38 and opposite normally lower free ends 44 and connecting means 46 for releasably joining these free ends.
As described in greater detail later, the hardtop storage apparatus 20 is mounted on an overhead support structure 32 of sufficient height above the underlying floor to enable an automobile 26 with a removable hardtop 24 to be parked below the storage apparatus without contacting the sling 22 when the sling is elevated with the sling straps gathered and secured about the lifting member 36. The sling 22 is engaged with the hardtop 24 of the parked automobile 26 by releasing the hardtop for separation from the automobile body, lowering the sling onto the top, extending the free ends 44 of the sling members 40 about opposite extremities of the hardtop and toward one another across the underside of the hardtop, and then joining the free ends of the sling members to one another by the connecting means 46 at the underside of the hardtop, as shown in full lines in FIG. 1. The winch 34 is then operated to lift the sling and hardtop to their broken line elevated storage positions of FIG. 1 in which the automobile 26 may be driven away and returned without contacting the elevated sling or hardtop. The sling 22 cradles the supported hardtop with the top resting on the joined lower free ends 44 of the sling members 40 extending across the underside of the top. Pivotally mounted on the support 30 are storage supports 47 which support the hardtop in its elevated storage position so as to remove the weight of the hardtop from the winch mechanism 34. The hardtop is replaced on the automobile by reversing this procedure.
Referring now in more detail to the illustrated hardtop storage apparatus, the hoist support 30 comprises a channel-shaped beam 48 firmly secured to the overhead support structure 32. This overhead support structure is normally the ceiling of a garage. The winch mechanism 34 comprises a rotary drum 50 situated between and rotatably mounted on the depending flanges 52 of the beam 48 for rotation on an axis normal to these flanges. Rigid on one end of the drum 50 is a worm wheel 56 which meshes with a vertical worm gear 56 rotatably mounted on one beam flange 52. Worm gear 54 is rotatable by a crank 58 to rotate the drum 50 in either direction. This crank is releasably connected by a releasable coupling 59 to the lower end of the worm gear for removal when not in use. The lifting member 36 of the winch mechanism 34 is a strap having an upper end fixed to the drum 50. This lifting strap extends over a roller 60 rotatably mounted between the beam flanges 52 and then downwardly to the sling 22. The lower end of the lifting strap is firmly fixed to the sling 22 at its support point 38.
The flexible members 40 of the sling 22 are straps including two straps 40r referred to herein as rear straps and a third strap 40f referred to as a front strap. The upper ends 42 of these sling straps are firmly joined to one another at or near the sling support point 38 with these joined upper strap ends disposed substantially in a common plane. As shown in FIG. 4, the two rear sling straps 40r extend in one direction from the sling support point 38 in diverging relation to one another and to a plane P which bisects the included angle between the rear straps and which plane is normal to the plane of and contains the longitudinal centerline of the winch lifting strap 36. The rear sling straps 40r extend through slots 61a in the ends of a stabilizing bar 61 whose function will be explained presently. The single front strap 40f extends in the opposite direction from the sling support point 38 with the longitudinal centerline of the front strap disposed substantially in the plane P.
Referring to FIG. 5, the lower free end 44 of each rear sling strap 40r has a single loop 62. The lower free end 44 of the front sling strap 40f has a plurality of loops 64 spaced along the strap. The strap connecting means 46 comprises a generally V-shaped tie hook including diverging arms 66 joined at one end by a flat apex portion 68 and inturned hook portions 70 at the other ends of the arms. The free ends 44 of the front and rear sling straps 40f, 40r are releasably joined by inserting the tie hook 46 through one loop 64 of the front strap to the position of FIG. 5 wherein the flat apex portion 68 of the hook is situated within the front strap loop and then inserting the hook-shaped free ends 70 of the tie hook arms 66 through the loops 62 of the rear straps, as shown. It is evident that the tie hook and loops comprise mating connecting elements which form a readily separable and engagable connecting means (46) and are readily engagable to positively join the free ends of the sling straps and readily separable to permit separation of these free ends. Accordingly, the connecting means 46 is adapted to be selectively engaged to positively secure the sling straps about the hardtop and separated to release the sling straps from the hardtop.
The pivoted hardtop storage supports 47 are similar to those described in my earlier mentioned U.S. Pat. No. 5,263,687. Each support includes a storage arm 72 pivoted at one end between the flanges 52 of the overhead support beam 30 on a horizontal axis normal to the longitudinal axis of the beam and a transverse storage base 74 on the lower end of the arm mounting cushions 76. The storage supports are rotatable between extended positions shown in solid lines in FIG. 1 and retracted positions shown in broken lines in FIG. 1. Mounted on the storage support arm 72 of each storage support 47 is a latch device 78 (FIG. 3) for releasably securing the support in its extended and retracted positions. Latch device 78 includes a latch pin 80 which is biased to the right in FIG. 3 by a spring 82 for selective engagement in a pair of latch holes 83 in one flange 52 of the support beam 30 to latch the storage support in its extended and retracted positions. Attached to the latch pin is a lanyard 84 which can be pulled to retract the latch pin and release the storage support from movement from one position to the other.
The manner in which the hardtop storage apparatus 20 is used to store the hardtop 24 of the automobile 26 will now be explained. When not in use supporting an automobile hardtop, the hardtop sling 22 is raised by the hoist 28 to an elevated position, and the sling straps 40 are gathered and secured about the lifting strap 36 in any convenient way such that the straps are prevented from contacting the automobile 26 when parked below the apparatus. The removable hardtop 24 of the automobile is stored by first latching the storage supports 47 in their broken line retracted positions of FIG. 1 and locating the automobile 26 below the storage apparatus in a hardtop transfer position in which the center of gravity of its hardtop 24 is vertically aligned as close as possible with the roller 60 over which the winch lifting strap 36 extends. The hardtop is released for separation from the automobile body and is then raised a small distance by hand to permit insertion of spacers 86, preferably cushioned spacers such as so-called gap cushions, between the front and rear ends of the hardtop and the underlying portions of the automobile body, that is between the front end of the hardtop and the top of the windshield frame 26a and between the rear end of the hardtop and the underlying rear portion 26b of the automobile body, as shown in FIG. 1. These spacers provide spaces or gaps between the ends of the hardtop and the underlying portions 26a, 26b of the automobile body through which the sling straps 40 are insertable, as described below. The spacers also prevent damaging contact of the hard top with the body as the top is lifted from the body.
The crank 58 of the winch mechanism 34 is now turned in a direction to lower the sling 22 onto the roof of the underlying hardtop. The free end 44 of the front sling strap 40f is then passed around and under the front end of the hardtop and to the underside of the hardtop through the gap between the front end and the upper edge of the underlying windshield frame 26a. The free ends 44 of the rear sling straps 40r are passed through the slots 61a in the stabilizing bar 61 which is positioned just above the rear end of the hardtop, as shown in FIG. 1, and then around and under the rear end of the hardtop and to the underside of the hardtop through the gap between the rear end and the underlying rear portion 26b of the automobile body. Finally, the free ends of the three straps are drawn toward one another across the underside of the hard top and joined at the underside of the hardtop by the tie hook 46, after which the hoist crank 58 is turned in a direction to lift the sling 22 and the hardtop 24 to their broken line elevated storage positions of FIG. 1. The storage supports 47 are then returned to and latched in their solid line extended positions of FIG. 1 wherein their bases 74 underlay the ends of the hardtop. The sling is then lowered slightly to rest the ends of the hardtop on the cushions 76 of the storage supports, as shown in FIG. 7 and thereby remove the weight of the hardtop from the sling and hoist. The hardtop is replaced on the automobile by reversing the above procedure. If desired, the manual winch mechanism 34 may be replaced by the motor driven winch mechanism 34a in FIG. 9 which is identical to the winch mechanism in my U.S. Pat. No. 5,263,687.
If the automobile 26 is not parked with the center of gravity of its hardtop 24 precisely aligned with the roller 60, the winch mechanism 34 will tend to pull the hardtop horizontally as well as vertically during the initial portion of the lifting operation. The spacers 86 prevent damaging contact of the hardtop with the automobile body in the event that the hardtop is pulled horizontally in this way. A unique feature of the invention resides in the fact that the sling 22 supports the elevated hardtop 24 with a cradling action. That is to say, the sling cradles the hardtop with the lower edges of the hardtop resting on and supported by the joined end portions of the sling straps 40 which extend across the underside of the hardtop. The sling 22 is adjustable to accommodate hardtops of different sizes by engagement of the tie hook 46 in different ones of the loops 64 in the front sling strap 40f. In this regard, it is evident that the sling 22 has an effective circumferential dimension measured along the sling straps 40f, 40r from the joined upper strap ends 42, through the strap connecting means or tie hook 46, back to the upper strap ends. This circumferential dimension is adjustable by selective engagement of the tie hook in the loops 64 of the front sling strap 40f. The stabilizing bar 61 retains the two rear sling straps 40r in spaced diverging relation at the rear of the hardtop 24 in order to assure proper balancing of the hardtop 24 by the sling 22.
The modified hardtop storage apparatus 100 of FIGS. 10 and 11 comprises a hardtop sling 22 and a hoist 28 which are identical to those of FIGS. 1-9 and a dust cover 102 which is identical to that of my U.S. Pat. No. 5,263,687 except that the dust cover. 102 includes an open ended sleeve 103 for receiving the stabilizing bar 61 of the sling 22. Accordingly, it is unnecessary to re-describe the sling 22, hoist 28, and dust cover 102 in elaborate detail. Suffice it so say that the dust cover 102 has a top portion 104 which is shaped to fit over the hardtop 24 in the manner illustrated in FIG. 11 and a rear flap 106 joined to the top portion along a rear lower edge 108 of the top portion. This flap is divided along the longitudinal centerline of the top portion into two flap portions 110 and has a zipper 112 for joining the flap portions to one another along their adjacent longitudinal edges in the manner shown in FIG. 10. The cover top portion 104 and flap portions 110 have zippers 114 for joining the top and flap portions along their side edges with the dust cover enclosing the hardtop 24, as shown in FIG. 10. The stabilizing bar sleeve 103 is secured to the outer surface of the cover top portion 104 just above and parallel to the rear lower edge 108 of the top portion 104. The sleeve is centered along the edge 108 and has a length slightly less than the distance between the stabilizing bar slots 61a.
The stabilizing bar 61 of the sling 22 is positioned within the cover sleeve 103 of the sling with the slotted ends of the bar extending beyond the ends of the sleeve, as shown. Extending through the top portion 104 of the dust cover 102 along or close to its rear lower edge 108 are a pair of slots rear 116 which are aligned with the slots 61a in the stabilizing bar 61 when the bar is positioned in the sleeve. Midway along the front edge of the cover top portion 104 is a front slot 118.
The support point 38 of the sling 22 is located above the top portion 104 of the dust cover 102. The two rear sling straps 40r extend rearwardly from the sling support point 38 over the top portion of the cover, then downwardly across the rear side of the top portion, then through the slots 61a in the stabilizing bar 61, and finally through the rear cover slots 116 to the underside of the cover. The single front sling strap 40f extends forwardly from the sling support point 38 over the top portion of the cover and through the front cover slot 118 to the underside of the cover.
The modified hardtop storage apparatus 100 of FIGS. 10 and 11 is used in much the same way as the storage apparatus 20 of FIGS. 1-9. Thus, when the storage apparatus 100 is not being used to support the automobile hardtop 24, the sling 22 and dust cover 102 are raised to an elevated position and the dust cover and sling straps are gathered and secured in any convenient way about the winch lifting strap 36 so as to not contact the automobile 26 when parked below the storage apparatus. Storage of the automobile hardtop 24 is accomplished by separating the hardtop from the automobile by means of the spacers 86, operating the winch mechanism 34 of the storage apparatus to lower the sling 22 and dust cover 102 onto the roof of the hardtop, unzipping the cover zippers 112, 114, if necessary, and spreading the dust cover over the hardtop, and then extending the free ends of the sling straps 40r, 40f across the underside of the hardtop and joining these strap ends in the same manner as explained earlier in connection with FIGS. 1-9. The dust cover is then zippered closed about the hardtop and the hoist 28 is operated to lift the covered hardtop to the elevated storage position of FIG. 10. The hardtop is replaced on the automobile by reversing this procedure.
It is evident at this point that this invention provides the following removable automobile hardtop handing procedure: providing an overhead hoist including a lifting member hanging downwardly from the hoist, and a sling attached to the lower end of the lifting member and adapted for releasable supporting engagement with the automobile hardtop, whereby the sling is adapted to be lowered by the hoist to a lower position wherein the sling is engagable with and releasable from the automobile hardtop and raised by the hoist to a raised position wherein the sling is disposed to support the hardtop in an overhead storage position, parking the automobile below the sling when the sling is in its raised position, and performing the following additional steps (A) to remove the hardtop from the automobile and store the hardtop when the hardtop is initially mounted on the body of the parked automobile and the following additional steps (B) to replace the hardtop on the automobile when the hardtop of the parked automobile is initially supported in said overhead storage position by the sling:
(A) manually lifting the automobile hardtop a small distance above the automobile body to an initial elevated position in which the hardtop portions are spaced from the body portions, placing supports between the hardtop and body to support the hardtop in this initial elevated position, engaging the sling with the hardtop, and operating the hoist to raise the hardtop from its initial elevated position to the overhead storage position,
(B) operating the hoist to lower the hardtop from the overhead storage position to an initial hardtop replacement position over the automobile body in which the hardtop portions are spaced from the body portions, placing supports between the hardtop and body to support the hardtop in this initial hardtop replacement position, releasing the sling from the hardtop, removing the supports, and manually lowering the hardtop onto the automobile body.
