Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spare tire holding device for an automobile or other vehicle.

An example of this type of device is disclosed in Japanese Utility Model Application Publication No. 51-119248, in which a jack is attached to a spare tire via a tire support member, and the jack is suspended from a hanger member provided on the underside of the vehicle body. It is known that the spare tire is fixed to the underside of the vehicle body by tightening the jacks.

However, in such a system, the spare tire is fixed to or removed from the underside of the vehicle body only by operating a jack, and therefore has the disadvantage that the fixing or removal operation is time-consuming.

In order to improve this inconvenience, the present invention operates the jack only during the final tightening or initial loosening of the spare tire, and tightens or loosens the spare tire more quickly by rotating the tire itself. It is designed to be tightened or loosened.

To explain this with reference to the illustrated embodiment, 1 indicates a vehicle body;
On the lower surface of the vehicle body 1, there is an engagement recess 3 that opens to the outside on one side.
A hanger member 5 is attached to the recess 3 and has a long groove 4 that is open on one side to the outside along the bottom wall.

Further, a tire support member 2 is attached to the spare tire a,
The support member 2 is formed into a plate shape that closely overlaps the tire wheel b, and has a plurality of pins 9 protruding from its upper surface corresponding to the tightening holes C of the tire wheel b, and the pins 9 are inserted into the tightening holes C. C to support the support member 2 so that it does not rotate around the tire a, and at the same time fix the tire a to the support member 2 in advance by forming some of them into bolts and attaching nuts 10 to them. The support member 2 includes a nut 6 that is rotatably supported via a support piece 12 having an annular inclined surface, and a locking member that is screwed onto the nut 6 and engages with the engaging recess 3. A cylindrical rotating member 1 which is welded to the screw rod 7 and has an engagement portion 15 for a foil wrench 14 at one end to rotate the nut 6 with respect to the screw rod 7.
A jack 16 consisting of 3 is provided.

The hanger member 5 is formed by bending a metal plate into a flanged channel shape, and the channel portion forms the engagement recess 3, and the long groove 4 bored in the bottom wall is formed on both sides of the opening side. is constructed one step higher than the others via step 11, and even if the tightening by the screw punch 7 and nut 6 becomes loose, several steps 1
1 prevents the screw punch 7 from moving toward the opening side and prevents it from falling off unnecessarily.

In the figure, 20 indicates a retaining portion formed by caulking the lower end of the screw punch 7.

According to the embodiment of the present invention configured as described above, the jack 16 attached to the spare tire a engages the engaging element 8 provided on the screw punch 7 with the engaging recess 3 of the hanger member 5. The nut 6 is suspended by the hanger member 5, and at that time, the nut 6 is frictionally engaged with the inclined surface of the support piece 12 under the load of the tire weight. Since the nut 6 rotates on the screw 7 by simply rotating the side of the tire A, it is easy to tighten and loosen the nut 6, and the end of tightening and the beginning of loosening can be easily tightened and loosened. The chisel nut 6 is tightened and loosened by rotating the wheel wrench 14 via the rotating member 13.

According to the present invention, the jack 16 attached to the spare tire a via the tire support member 2 is rotatably supported via the support piece 12 provided on the support member 2 and having an annular inclined surface. a screwdriver 7 having an engaging element 8 which is screwed onto the nut 6 and engages with the hanger member 5; Engagement part 15 of foil wrench 14 at one end
The jack 16 is tightened and loosened not only by the rotation of the rotation member 13 but also by the rotation of the tire a side, so that its workability can be significantly improved. have an effect.
