Description
Background and Summary of the Invention
This invention relates generally to roof systems and specifically to an automotive vehicle having a convertible roof system.
It is known to provide a retractable hard-top roof system for a convertible automotive vehicle. Traditionally, such a retractable hard-top roof system employs a plurality of rigid roof panels which can be retracted for stowage into the trunk of the automotive vehicle. Such a system is disclosed in U.S. Pat. 2,939,742 entitled "Foldable Vehicle Top" which issued to Dardarian et al. on Jun. 7, 1960. This system, however, pre-empts valuable storage space within the trunk.
More recently, various retractable roof systems have been developed which retract a rigid roof into a passenger compartment of an automotive vehicle. These systems stow the retracted roof in a substantially vertical orientation behind either the front or rear seats. While these conventional designs maintain some of the storage space within the trunk, the retracted roof is often stored in an unsightly manner. Examples of two such systems are disclosed in U.S. Pat. No. 5,195,798 entitled "Retractable Roof For Vehicles" which issued to Klein et al. on Mar. 23, 1993, and U.S. Pat. No. 4,854,634 entitled "Upper Body Structure For A Convertible Vehicle" which issued to Shiraishi et al. on Aug. 8, 1989.
It is also common to employ a tonneau cover in combination with a convertible soft-top roof. Examples of these tonneau covers are disclosed in the following U.S. Pat. Nos. 5,052,740 entitled "Folding Top For Vehicles" which issued to Bauer et al. on Oct. 1, 1991; 4,799,729 entitled "Tonneau Cover Mechanism For Convertible Automobiles" which issued to Muscat on Jan. 24, 1989; 4,778,215 entitled "Flexible Roof For Motor Vehicles" which issued to Ramaciotti on Oct. 18, 1988; and, 2,747,928 entitled "Folding Top Compartment Cover" which issued to Olivier et al. on May 29, 1956; all of which are incorporated by reference herewithin. These exemplary tonneau covers are often disadvantageous in that they have essentially the same front edge configuration when the roof is in an extended position and when the roof is in a retracted position. Thus, undesirable gaps are often present when either the roof is fully extended or retracted. Therefore, it would be desirable to have an escutcheon which can be extended to a functional position or retracted to a hidden position so as to aesthetically cover any gaps between a roof and an adjacent body of an automotive vehicle while avoiding the aforementioned problems.
Moreover, most conventional automotive vehicles having convertible roofs provide a balance link which is attached to a forward portion of the roof. This balance link aids in supporting and moving the roof during extension and retraction thereof. Examples of such balance links are shown in the following U.S. Pat. Nos.: 4,895,409 entitled "Convertible Vehicle Body Structure" which issued to Konishi et al. on Jan. 23, 1990; 2,768,024 entitled "Retractable Rigid Automobile Top" which issued to Spear on Oct. 23, 1956; and the aforementioned Shiraishi et al. patent. While these exemplary patents show a variety of balance link mechanisms, they all appear to be visible from within the automotive vehicle when the roof is in its extended position. Therefore, it would be desirable to provide an interior trim panel mounted upon an interior surface of a roof which substantially hides an intermediate portion of a balance link therein when the roof is in an extended position so as to avoid the aforementioned problems.
In accordance with the present invention, the preferred embodiment of a new and useful apparatus for use in an automotive vehicle having a convertible roof system is comprised of an escutcheon which is juxtapositioned proximate with a roof and movable between a functional position and a hidden position. The functional position allows the escutcheon to be substantially visible external to the automotive vehicle and the hidden position allows the escutcheon to be substantially hidden from view external to the automotive vehicle. The escutcheon is positioned in the functional position when the roof is in a retracted position. Alternately, the escutcheon is positioned in the hidden position when the roof is in an extended position. The present invention escutcheon can also be used in combination with a movable tonneau cover.
The escutcheon of the present invention is advantageous over traditional tonneau covers in that the present invention escutcheon can be moved to various positions thereby providing a close-out apparatus having varied configurations for aesthetically covering gaps against a roof when the roof is both fully extended and fully retracted. Accordingly, the present invention more effectively covers these gaps as compared to conventional designs.
In another aspect of the present invention, an interior trim panel is attached to an inside surface of a roof. The interior trim panel substantially hides an intermediate portion of a balance link therein as viewed from inside a passenger compartment of an automotive vehicle when a roof is in a fully extended position. The interior trim panel of the present invention is advantageous over conventional designs since balance links which require an extensive path of movement during retraction can still be substantially hidden from view when the roof is in an extended position.
Additional advantages and features of the present invention will become apparent from the following description and appended claims, taken in conjunction with the accompanying drawings.

Detailed Description of the Preferred Embodiment
An automotive vehicle 20 is shown in FIGS. 1 and 2. Automotive vehicle 20 is constructed with a body 22 and a retractable hard-top roof 24. Body 22 is farther divided into a passenger compartment 26 and a trunk 28. The passenger compartment 26 and trunk 28 are separated by an exterior tulip panel 30 and an interior metallic seat back panel 32. Furthermore, a pair of rear wheel houses 34 protrude upwardly and inwardly within trunk 28 and passenger compartment 26. Also, a front header 36 extends transversely across the top of a windshield 38. A storage space 40 is located between a pair of front seats 42 and trunk 28 where rear seats (not shown) may be juxtapositioned. Referring to FIGS. 1, 2 and 10, retractable hard-top roof 24 is comprised of a front roof section 50, a rear roof section 52, a tonneau cover 54, an escutcheon 56, a balance link 58, a pair of retraction mechanisms 60 and a roof biasing device 62.
Front roof 50 is a rigid panel having an exterior surface 64 and an interior surface 66. Front roof 50 further has a latching and alignment mechanism (not shown) which is disengagably attachable with front header 36 when front and rear roofs 50 and 52, respectively, are in a fully extended position 70. Front roof 50 also includes any structural supports such as side rails or inner panels (not shown) attached thereto.
As can best be observed in FIGS. 1, 10 and 12, rear roof 52 has an exterior surface 72 and an interior surface 74. Rear roof 52 further includes any structural supports such as side rails or inner panels 76 and 78 attached thereto. In its extended position 70, a lower portion 80 of rear roof 52 is adjacent with a theoretical surface defined by tulip panel 30 and the substantially horizontal portions of quarter panels 90. Front roof 50 and rear roof 52 are pivotably coupled to one another by a hinging device 94. Subsequently, when front and rear roofs 50 and 52, respectively, are in a fully retracted position 70', exterior surface 64 is in a horizontally stowed orientation between front seats 42 and trunk 28. Front roof 50 and rear roof 52 are preferably made from a lightweight but strong material such as sheet aluminum.
Referring to FIGS. 2, 3, 5 and 10, tonneau cover 54 is defined by an aesthetically pleasing external surface 100 and an internal surface 102, both of which are bordered by a forward facing edge 104, a rearward facing edge 106 and a pair of transversely disposed side edges 108 and 110. Forward facing edge 104 of tonneau cover 54 has a generally C-shaped plan view configuration. A pair of scissor arm linkage mechanisms 120 movably couple tonneau cover 54 to body 22 of automotive vehicle 20. Each scissor arm linkage mechanism 120 is comprised of a first set of linkage arms 122 which are pivotably coupled to body 22 at end 124. A second set of linkage arms 126 are pivotably coupled to first set of linkage arms 122 at pivot 128. Second set of linkage arms 126 are drivably connected to a fractional horse power direct current electric motor 130 at end 132. Ends 134 and 136 of first and second sets of linkage arms, respectively 122 and 126, are pivotably connected to a support 138. Support 138 is mounted, in turn, to internal surface 102 of tonneau cover 54. Thus, tonneau cover 54 is movable from a closed position 140 (FIG. 10) to an open position 140' (FIG. 5). Additionally, a pair of locator pins 142 project from internal surface 102 of tonneau cover 54 for positional alignment with a congruent receiving means within body 22 of automotive vehicle 20. Tonneau cover 54 is preferably made from aluminum. Furthermore, external surface 100 of tonneau cover 54 is painted to correspond with the adjacent body 26. Alternately, one skilled in the art would know that a pair of gooseneck-type arms can also be used to pivotably couple tonneau cover 54 to body 26 of automotive vehicle 20.
Escutcheon 56 is defined by a central member 170 having a substantially transverse orientation thereto and a pair of lateral members 172 extending in a substantially forward direction from curved ends of central member 170. Central and lateral members, respectively 170 and 172, further have an aesthetically pleasing appearance face 174 and a backside face 176. Escutcheon 56 is preferably formed from a resin impregnated sheet of fiberglass with appearance face 174 being defined by a vinyl covering. Central member 170 is coupled to tonneau cover 54 by a pair of steel hinges 190. Each hinge 190 has a hinge spring 192 coiled around a pivot pin so as to bias hinge 190 and central member 170 in a functional position 220 (FIG. 5). Hinges 190 are mounted to central member 170 and tonneau cover 54 through a plurality of screws. In cooperation therewith, a fractional horse power direct current electric motor or actuator 194 is centrally mounted upon tonneau cover 54. Actuator 194 operably drives a pair of force transmitting means such as a cable 196 which can be obtained from Combiner Incorporated or Hylex Incorporated. Cable 196 is positionally maintained at a distal end 198 thereof by a guide 200 having a pair of rollers rotatably journalled therein. Distal end 198 of cable is pivotably connected to a flange 202 projecting from a portion of bracket 190 coincidental with central member 170. Thus, actuator 194 pulls cable 196 thereby folding central member 170 to a hidden position 220', (FIG. 10) adjacent to internal surface 102 of tonneau cover 54.
A folding mechanism 250 is constructed with a first plate 252, a second plate 254 and a plurality of linkages 256. First plate 252 is screwed to backside face 176 of each lateral member 172 and second plate 254 is screwed upon backside face 176 of central member 170. Three arcuately-shaped linkages 256 pivotably couple first plate 252 to second plate 254 for controlling three-dimensional folding movement therebetween. A folding mechanism spring 258 serves to bias folding mechanism 250 in functional position 220. First plate 252 further has a flange 260 protruding therefrom upon which a connecting arm 262 and a control link 264 are pivotably attached. Control link 264 is oppositely coupled with a tab 266 protruding from guide 200 thereby causing each lateral member 172 to foldably move in cooperation with the movement between central member 170 and the adjacent tonneau cover 54. A potentiometer or limit switch 280 is provided to determine the relative orientation between central member 170 and tonneau cover 54. When a predetermined position is reached, limit switch 280 will stop actuator 194. Limit switch 280 can be used in combination with the system disclosed in U.S. Pat. No. 5,225,747 entitled "Single-Button Actuated Self-Correcting Automatic Convertible Top" which issued to Helms et al. on Jul. 6, 1993 and which has a common assignee with the present invention; this patent is incorporated by reference herewithin. Of course, a limit switch can be employed between lateral members 172 and central member 170. As can best be observed in FIGS. 3 and 15, control link 264 has a ball socket 268 and screw 270 attachment which are partially trapped within a yoke 272 at each end thereof. Additionally, an elastomeric bumper 290 is mounted upon each lateral member 172 to prevent undesirable noise or sudden impact during folding.
Referring to FIGS. 10 and 16 through 17, each retraction mechanism 60 is comprised of a plurality of roof linkages 350, a cam 352 and a fractional horse power direct current electric motor 354. A first roof linkage 356 is pivotably coupled to a tab 358 extending from lower portion 80 of rear roof 52. A second roof linkage 360 is pivotably coupled to body 22 of automotive vehicle 20 (see FIG. 1). Acting in concert therewith, a third roof linkage 361 is pivotably coupled to first roof linkage 356 and a package shelf structure 363. Package shelf structure 363 is covered by a shelf trim panel 365 (see FIG. 11) containing a pair of raised holding formations. Moreover, rear roof 52 is pivotably coupled to body 22 at pivot 362. Cam 352 is defined by a sector gear 364 having a set of teeth peripherally located thereon and further having second roof linkage 360 extending therefrom. Motor 354 drivably rotates cam 352 which, in turn, actuates the plurality of roof linkages 350 during extension and retraction of front and rear roofs 50 and 52, respectively.
Roof biasing device 62 acts in concert with retraction mechanisms 60 so as to bias roof 24 toward extended position 70. This inhibits undesirable stress build-up and prevents uncontrollable movement of roof 24 during retraction due to the significant weight thereof. Roof biasing device 62 is comprised of a transversely oriented axle 450 which is mounted upon first roof linkage 356 adjacent to either end 452 of axle 450 for corresponding movement therewith. A pair of coiled torsion springs 454 are wrapped around portions of axle 450 proximate to each end 452. An inboard end 456 of each coiled spring 454 is affixed to a brace 458 projecting normal to a longitudinal axis of axle 450. An outboard end 460 of each coiled spring 454 is oppositely attached for rotational movement to third roof linkage 361 which is journalled about axle 450. Coiled spring 454 is caused to be further wound due to the rotational movement of outboard end 460 of coiled spring 454 in relation to inboard end 456 thereof during retraction of the plurality of roof linkage 350. Alternately, axle 450 is firmly mounted to body 26 (see FIG. 1) and outboard end 460 of each coiled spring 454 is fit within a keyhole slot located in a movable roof linkage or hinge.
Balance link 58 is defined by a proximal end 500, a distal end 502 and an intermediate portion 504 therebetween. This is best illustrated in FIGS. 10 through 12. Balance link 58 is preferably a solid steel member but may alternatively be hollow. Distal end 502 is pivotably coupled to the plurality of roof linkages 350 and distal end 502 of balance link 58 is directly coupled to a side rail of front roof 50 or to hinge 94 which foldably connects front roof 50 to rear roof 52.
An interior trim panel 550 is affixed to rear roof 52 adjacent to interior surface 74 thereof. Interior trim panel 550 is comprised of a substantially resin impregnated compression molded fiberglass substrate 552 upon which a cloth or vinyl covering material 554 is adhered. Interior trim panel 550 further has a somewhat vertically elongated pocket 556 formed therein with an elongated forward facing open portion 558 being in registry with pocket 556. Open portion 558 allows access of intermediate portion 504 of balance link 58 therein when front roof 50 and, in turn, balance link 58 are located in extended position 70. Accordingly, pocket 556 acts to somewhat hide intermediate portion 504 of balance link 58 when viewed from within passenger compartment 26 of automotive vehicle 20 (see FIG. 1).
An alternative embodiment of an interior trim panel 570 is shown in FIGS. 13 and 14. In this embodiment, interior trim panel 570 has a forward facing lip 572 and a transversely facing body 574 which fully hides intermediate portion of balance link 58 therein. Nevertheless, intermediate portion 504 of balance link 58 is allowed to translate in a fore and aft direction between transversely facing body 574 and inner panel 78 of rear roof 52.
The series of sequential extending positions of front roof 50, rear roof 52, escutcheon 56, tonneau cover 54 and retraction mechanism 60 are shown in FIGS. 4 through 10. In FIG. 4, front roof 50 and rear roof 52 are shown in retracted position 70'. Accordingly, interior surface 66 (see FIG. 10) of front roof 50 is folded in a clam-shelled manner against interior surface 74 (see FIG. 12) of rear roof 52. Disposed adjacent thereto, tonneau cover 54 is located in closed position 140 while central member 170 and both lateral members 172 are extended in their functional positions 220 so as to rest upon exterior surface 64 of front roof 50. Thus, central and lateral members, respectively 170 and 172, serve to aesthetically cover any gaps between front roof 50 and the adjacent tonneau cover 54.
Referring to FIG. 5, tonneau cover 54 is pivotably raised to open position 140'. This allows front and rear roofs 50 and 52, respectively, to be extended from storage space 40. As can be observed in FIGS. 6 and 7, lateral members 172 are then folded inward upon central member 170. Subsequently, FIGS. 8 and 9 then show lateral member 172 fully folded against central member 170 and central member 170 fully folded against internal surface 102 of tonneau cover 54. Therefore, escutcheon 56 is shown located in its hidden position 220'.
Referring to FIG. 10, tonneau cover 54 is subsequently lowered to its closed position 140 adjacent to lower portion 80 of rear roof 52. In this position, escutcheon 56 is fully hidden from view external to automotive vehicle 20 (see FIG. 1). Additionally, as can be observed in FIG. 12, a quarter window assembly 700 is provided which can be extended or retracted from within rear roof 52. Returning to FIG. 10, the present invention provides a close-out apparatus having differing front edge configurations when roof 24 is in its extended position 70 and in its retracted position 70' (see FIG. 4).
While various embodiments of the apparatus of the present invention have been disclosed, it will be appreciated that many modifications may be made without departing from the present invention. For example, a soft-top roof or a combination of hard-top and soft-top sections within a roof may be employed in combination with the disclosed apparatus. Also, the escutcheon of the present invention may be used without a tonneau cover. Furthermore, the escutcheon may have alternate shapes and folding or sliding segments thereto. The hinging, folding and scissor arm mechanisms may all be substituted by gear, gooseneck, ball and socket, pneumatic, hydraulic or other pivoting devices. Moreover, the actuator may comprise a manually operated crank. Force transmitting device can alternately employ a rod to move the escutcheon in relation to the tonneau cover. While various materials have been disclosed in an exemplary fashion, it would be obvious to one skilled in the art to provide alternate materials. It is intended by the following claims to cover these and any other departures from the disclosed embodiments which fall within the true spirit of this invention.
