[0003]

[Problems to be solved by the invention]

 However, when the door is relatively large and heavy, extra labor is required. In particular, it is inconvenient when handling the rear-end push-up type rear door. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a vehicle door support device that sandwiches and supports a door so that the vehicle door can be removed and attached by one person.

[0004]

[Means for Solving the Problems]

 According to the means of the present invention for solving the above-mentioned problems, a jack is mounted on a seat base and a shaft of the jack is mounted on an angle adjuster and a pinch so that various kinds of automobile doors can be supported. Connect them so that they can be adjusted in height. In the pinch rack, two pin rods that can support and adjust the distance between the window frames of the door are attached to one vertical outer tube so that they can be freely moved up and down by a stereotactic socket and thumb screw. Attached and fixed to the middle part of the outer tube with the angle adjusting set, the outer pipe moves up and down together with the jack when the jack pushes up and down the angle adjusting set. If the angle adjuster adjusts the angle, the outer tube will also be inclined to that angle, so that the pincer can be adapted to the structure of various car doors. Furthermore, the inner tube is fitted into the lower end of the outer tube, and the pin penetrates into the lower end of the outer tube and pierces one of a number of equally-spaced pin holes in the inner tube. So that the height of is adjusted.

[0005] Further, the lower end of the inner pipe is fixed to the middle part of the horizontal pipe. Support pipes are fitted into both ends of the horizontal pipe, and the extended length thereof can be adjusted and fixed with thumb screws. Keep it. Further, each support tube has an L-shaped support plate attached thereto, which can be freely moved to change its position, and a cushion is stuck on the L-type support plate to support the lower edge of the door of the automobile and to be damaged. To avoid sticking.

The angle adjusting set 3 includes a fixed rod 31, a connecting rod 32, a fixed arm 33, and a guide rail 34. One end of the fixing rod 31 is fixed to the top end of the shaft 22 of the jack 2, the other end is connected to the connecting rod 32, and the fixing rod 31 can be tightened or loosened by tightening a tightening screw 311. Further, another end of the connecting rod 32 is fixed to the outer tube 41 of the sandwiching rack 4, and a vertically fixed arm 33 is fixed on the middle stage of the connecting rod 32. The upper end of the fixed arm 33 is an arc. The guide rail 34 has an arcuate guide hole 341 and the lower end of the guide rail 34 has a tightening screw 311 inserted into the lower end of the guide hole 341 so that the guide rail 34 has an arc-shaped guide hole 341. The guide rail 34 is moved with respect to the fixed bar 31 so that the angle of the fixed arm 33 with respect to the fixed bar 31 can be changed.

The pinch rack 4 includes a vertical outer tube 41, two horizontal pinches 42, 43, a vertical inner tube 44, and a horizontal tube 45. The outer tube 41 is fixed to one end of the connecting rod 32 of the angle adjusting set 3 at an appropriate position, and locating sockets 411 and 412 are movably attached to upper and lower ends thereof, respectively. The sockets 411 and 412 are respectively held by penetrating the lateral pin bars 42 and 43. Further, cushions 421, 431 are firmly attached downward at one end of the pin bars 42, 43 so as to prevent the paint from being damaged when the car door is pinched. In addition, a V-shaped notch 432 is formed in the cushion 431, and the V-shaped notch 432 is fitted around the edge of the door glass to stabilize. Thumb screws 413 and 414 are attached to the localization sockets 411 and 412, respectively, and the localization sockets 411 and 412 are moved up and down along the outer tube 41 to adjust the distance between them. Screw it firmly onto 1. At the same time, the distance between the pincer bars 42, 43 extending from the stereotaxic sockets 411, 412 to the left and right can be adjusted and fixed with the thumb screws 413, 414. The lower end of the vertical outer tube 41 fits into the inner tube 44, so that a pin 415 can be inserted into the lower end thereof. The length of the outer tube 41 and the inner tube 44 is adjusted according to the length of the door of the automobile, and then fixed with the pins 415. Further, the lower end of the inner pipe 44 is fixed to the center of the horizontal pipe 45, and both ends of the horizontal pipe 45 are fitted into the support pipe 451, and the support pipe 451 extends from the horizontal pipe 45 with thumb screws 452, 453. After adjusting the height, the support pipe 451 is tightly fastened to the horizontal pipe 45. The support tube 451 is provided so that the L-shaped support plate 454 can be slid over the support tube 451 and can be moved. Further, a cushion 456 is attached to the upper surface of each support plate 454 to protect the paint from being damaged when the lower end of the vehicle door is received and supported.

When using the vehicle door support device, first, the jack is operated to raise the angle adjusting set 3 and the pincer 4 appropriately to the height of the door, and then to the dimensions of the door. In addition to adjusting the distance between the pinch rods 42 and 43 and the support pipe 451 of the horizontal pipe 45 by turning the thumb screws 413 and 414, even if the pin hole 441 of the inner pipe 44 in which the pin 415 is fitted is selected, The distance between 42 and 43 and the support tube 451 can be adjusted. Therefore, the pincers 42 and 43 pinch the window frame of the door, adjust the length of the support pipe 451 extending from the horizontal pipe 45 with the thumb screws 452 and 453, fix the pipe, and fix the door with the support plate 454. , So that the door is supported and stabilized by the pincer 4. In this way, the task of removing the door can be done alone.

Second Embodiment A second embodiment of the present invention has substantially the same structure as the first embodiment, as shown in FIGS. 3 and 4, except for the pin 42 of the outer tube 41. , 43 so that the two pinch bars 46 provided with pinch hooks 461 can be fixed after moving their positions on the outer tube 41, and the L-shaped support plate 454 of the support tube 451 can be held down by the pressing bar 5 Each holding rod 5 is composed of an outer pipe 51 and an inner pipe 52, and a positioning socket 53 and a thumbscrew 54 are attached to each support pipe 451. The lower end of each outer pipe 51 is a height adjusting screw rod. The upper end of the height-adjusting screw rod 55 is screwed to the inner tube 52, and the upper end of each inner tube 52 is pasted with a cushion. Thus, the height of the holding rod 5 is adjusted by the length of the extension of the inner tube 52.

In the above-described second embodiment, when removing the rear door of a light van, a leisure car, or the like, as shown in FIG. 5, loosen the tightening screw 311 of the fixing rod 31 of the angle adjusting set 3 to fix it. The arm 33 is pushed up together with the connecting rod 32 so that the frame 4 is inclined as shown in FIG. 5, and then the tightening screw 311 is firmly tightened. Then, the pinch rack 4 is raised to an appropriate height, and the pinch hooks 461 of the two pinch bars 46 are hooked on the lock hooks of the rear door to adjust the distance between each pinch bar 46 and each holding bar 5. After that, the inner pipe 52 of each presser bar 5 is extended with each height adjusting screw 55 to securely support the rear door so that the removal operation can proceed. FIG. 6 shows a state in which the position of the pin 46 is adjusted to support the push-up type rear door of the small-sized vehicle according to actual necessity.

(Third Embodiment) FIGS. 7 and 8 show a third embodiment of the present invention. This third embodiment has substantially the same structure as the first embodiment, and the clamp 4 is upright. The pinch bars 42 and 43 are set on the outer tube 41. The difference is that the two support tubes 451 at both ends of the horizontal tube 45 are respectively L-shaped support plates of the second embodiment. 454 and the holding rod 5 are provided. Therefore, the third embodiment is applied to the removal of the door of a light truck or the front door of a truck.
