【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a state where a spare tire supporting device according to an embodiment of the present invention is applied to a rear portion of a vehicle body.

In the figure, a pair of shaft support parts 11a and 11b are horizontally fixed at intervals below the surface (outer wall surface) of the rear door 10 of the vehicle body, and the shaft support parts 11a and 11b are respectively set in a vertical plane. One end of the pipe-shaped vertical frames 12a, 12b is rotatably supported. A pipe-shaped horizontal frame 13 is connected to the other ends of the vertical frames 12a and 12b, and a carrier supporting portion 14a that is rotatable about the horizontal frame 13 is supported in the middle of the horizontal frame 13. Has been done. The shaft support 11, the vertical frame 12 and the horizontal frame 13 form a link mechanism.

The carrier supporting portion 14a constitutes an upper portion of the carrier (holding mechanism) 14, and the carrier main body 14c is connected to the carrier supporting portion 14a via the carrier frame 14b. The carrier main body 14c is formed in a trapezoidal shape that protrudes rearward of the vehicle body, and three bolts (fixing tools) 14c1 for fixing the spare tire 20 are provided on the rear side protruding surface, and the front side opening surface peripheral edge is formed. Is connected to the carrier frame 14b. A horizontal fixing bar 14b1 is provided in the middle of the carrier frame 14b.

Torsional springs (biasing mechanisms) 15a and 15b are provided at the shaft support portions 11a and 11b, and the torsion springs 15a and 15b have one end fixed with fixing portions 15a1 and 15b1. The vertical ends 12a and 12b are urged toward the rear door 10, respectively, while being fixed above the shaft support parts 11a and 11b and the other ends being fixed along the vertical frames 12a and 12b. The force exerted by the torsion springs 15a and 15b is set to be sufficient to bear the own weight of the vertical frame 12, the horizontal frame 13, and the carrier 14.

Further, the vertical frame 12b is provided with a stopper 16 for preventing the vertical frame 12b from being separated from the rear door 10 by a predetermined angle or more, and one end of the stopper 16 is pivotable to the rear door 10. A connected first link bar 16a and a second link bar 16b having one end rotatably connected to the first link bar 16a and the other end pivotally connected to the vertical frame 12b. It consists of and.

When the vertical frames 12 a, 12 b are rotated around the shaft supporting portions 11 a, 11 b as a fulcrum to come close to the rear door 10, the position of the rear door 10 facing the bar 14 b 1 of the carrier 14 is at that position. A lock mechanism 17 for fixing the bar 14b1 is provided, and the lock mechanism 17 can be remotely locked and unlocked by a lever 17a extending upward. Further, elastic cushioning materials 18a and 18b are provided at positions of the rear door 10 facing the vertical frames 12a and 12b.

Next, the operation of this embodiment having the above configuration will be described. 2 and 3 are views showing a process of removing and installing the spare tire 20, in which the solid line shows a normal state and the alternate long and short dash line shows a descending state during removal. Normally, the vertical frames 12a and 12b are held vertically. When mounting the spare tire 20, the lever 17a of the lock mechanism 17 is operated to release the fitting state between the bar 14b 1 and the lock mechanism 17. When the upper ends of the vertical frames 12a and 12b are pulled down to the near side, the carrier 14 is supported by the horizontal frame 13 and moves downward. At this time, the carrier support portion 14a and the horizontal frame 13 rotate and the carrier 14 descends while maintaining the vertical state.

When the carrier 14 reaches the lowermost position, the stopper 16 is fully extended and cannot be lowered any more. In the lowermost position, the height of the spare tire 20 placed on the ground and the height of the carrier body 14c are substantially the same, and the spare tire 20 can be fixed to the carrier 14 by the bolt 14c1 without lifting. After fixing the spare tire 20 to the carrier 14, the spare tire 20 is lifted within the movable range of the vertical frames 12a and 12b. When the vertical frames 12a and 12b are in the vertical state, the bar 14b1 of the carrier 14 contacts the lock mechanism 17 and is locked.

FIG. 4 shows another embodiment of the present invention. In this embodiment, dampers 19a and 19b are used instead of the torsion springs 15a and 15b. The dampers 19a and 19b are composed of cylinder-piston type dampers, and the cylinder-side end portion is attached to the rear door 10 by means of fixed portions 19a1 and 19b1 so as to be pivotable, and the piston-side end portion is attached. It is attached to the vertical frames 12a, 12b so as to be pivotable by fixing portions 19a2, 19b2. Then, the vertical frames 12a and 12b are urged to be drawn toward the rear door 10 side.

Also in this embodiment, the spare tire 20 is detached and attached in the same manner as in the above embodiment. The dampers 19a and 19b support the loads of the vertical frame 12, the horizontal frame 13, and the carrier 14 and reduce the effort of attaching and detaching the spare tire 20. Further, due to the damping force of the damper 19, the movement becomes slower when the vertical frame 12 is pulled out. In the above embodiment, the lower ends of the vertical frames 12a and 12b are pivotally attached to the rear door 10 so that the carrier 14 descends to the detachable exchange position in the vertical plane. The same operation may be performed by a link mechanism consisting of.

Further, regarding the force of the torsion spring 15 and the damper 19 for urging the vertical frame 12, not only the load of the vertical frame 12, the horizontal frame 13 and the carrier 14 is loaded, but also the pulling force is further increased. You can In this case, the burden of work can be reduced when the carrier 14 is pulled up to the normal position with the spare tire 20 attached.
