Abstract

An open top automobile body having a hoop member which is mounted for swinging movement between an erected position and a retracted position. A rigid roof panel is removably mounted to extend between the front windshield and the hoop member. A foldable rear hood having a rigid transparent glass is provided to cover the rear body section. The rear hood is secured to the rear body section at a position below the upper edge of the rear body section. A peripheral hood tensioning link is provided to force the hood against the upper edge of the rear body section substantially over an entire outer periphery of the hood link.

Claims

1. An open top automobile body including a body structure having a front windshield section, a rear body section comprising opposite side panels and a rear section, said rear body section having an upper edge portion defining an open top, a hoop member of a substantially inverted U-shape having a pair of leg portions swingably mounted respectively on the opposite side panels for movement between an erected position wherein the hoop member extends substantially upright and a retracted position wherein the hoop member is retracted in the rear section, a rigid roof panel adapted to be placed between the front windshield section and the hoop member in the erected position, foldable rear hood means having a front edge portion secured to the hoop member and side and rear edge portions secured to said rear body section of the body structure, the improvement resides in that said side and rear edge portions of the rear hood means are secured to the rear body section at portions below the upper edge of the rear body section, substantially U-shaped peripheral hood tensioning link means being provided for movement between an operative position wherein it cooperates with the upper edge of the rear section of the body structure to hold the rear hood means between the link means and the upper edge of the rear body section over substantially an entire outer periphery of the substantial U-shaped peripheral hood tensioning means, and an inoperative position wherein the link means is below the upper edge of the rear body section to release the rear hood means, and moving means beng provided for moving the hood tensioning link means to the operative position when the hoop member is moved to the erected position and to the inoperative position when the loop member is moved to the retracted position.

2. An automobile body in accordance with claim 1 in which the moving means includes means for pivotably connecting leg portions of the hood tensioning link means to the leg portions of the hoop member and flexible belt means connecting an intermediate portion of the link means to an intermediate portion of the hoop member.

3. An automobile body in accordance with claim 1 in which said rear hood means includes a transparent panel and a flexible part around the transparent panel, said hood tensioning link means being provided with means for receiving a rear edge portion of the transparent panel in the inoperative position.

4. An automobile body in accordance with claim 3 in which said receiving means includes deck means formed in an intermediate portion of the hood tensioning link means.

5. An automobile body in accordance with claim 3 in which said receiving means includes at least one forward projection formed in an intermediate portion of the hood tensioning link means.

6. An automobile in accordance with claim 1 in which said rear hood means includes a transparent panel and a flexible sheet around said transparent panel, an upper hood tensioning linkage being provided for engagement with said flexible sheet between the hoop member and the transparent panel to tension the flexible sheet.

7. An automobile body in accordance with claim 6 in which said upper hood tensioning linkage is of an inverted U-shape having a pair of leg portions pivotably connected with the rear body section.

8. An automobile body in accordance with claim 7 in which said leg portions of the upper hood tensioning linkage are connected to the rear body section through lower links.

9. An automobile body in accordance with claim 8 in which said leg portions of the upper hood tensioning linkage are pivotably connected with upper ends of said lower links which are pivotably connected with said rear body section, said leg portions of the upper hood tensioning linkage being pivotably connected with the hoop member.

10. An automobile body in accordance with claim 9 in which each said leg portion of the upper hood tensioning linkage is connected with its respective said lower link at a rearwardly offset position relative to the pivotal connection between the upper hood tensioning linkage and the hoop member.

11. An automobile body in accordance with claim 7 in which the leg portions of the upper hood tensioning linkage are connected to the rear body section at points lower than points where the leg portions of the hoop member are connected with the rear body section.

12. An automobile body in accordance with claim 7 in which said link moving means includes means for pivotably connecting leg portions of the hood tensioning linkage to the leg portions of the hoop member and flexible belt means connecting an intermediate portion of the linkage to an intermediate portion of the hoop member, said flexible belt means being passed through the upper hood tensioning linkage.

13. An automobile body in accordance with claim 1 in which said peripheral hood tensioning link means includes a rear link member of a substantially U-shape having a pair of forwardly extending legs and a pair of front link members having rear ends pivotably connected with the legs of the rear link member and forward end pivotably connected with said hoop member.

14. An automobile body in accordance with claim 1 in which said leg portion of the hoop member has a first plate which is secured at an upper end portion and an intermediate portion of the first plate to the leg portion, a substantially planar second plate being secured at an upper end and a lower end with upper and lower ends of the first plate, the lower ends of the first and second plates being pivotably connected to the rear body section.

15. An automobile body in accordance with claim 13 in which the legs of the rear link member are connected with the front link members through pivot connecting means which allows the front link members to be folded downwardly but prevents the front link members from being folded upwardly from a position wherein the front and rear link members extend substantially straight.

16. An automobile body in accordance with claim 1 in which said rear section of the rear body section includes a substantially transversely extending structure comprising an outer panel and an inner panel which are connected together to form a structure of closed cross-section, the rear edge portion of the rear hood means being connected to a lower surface of the inner panel, said structure of closed cross-section having an upper edge which defines a part of the upper edge portion of the rear body section and carrying seal means for cooperation with the peripheral hood tensioning link means.

17. An automobile in accordanace with claim 16 in which said side panels comprises an outer panel and inner panel which are connected together at upper edges thereof, said side edge portions of the rear hood means being connected to said inner panel of the side panel, said upper edges of the outer and inner panels carrying seal means for cooperation with the peripheral hood tensioning link means.
