Description

[Detailed description of the invention] The present invention relates to a spare tire support device for an automobile, and in particular to an improvement of a spare tire support device for supporting a spare tire in a suspended state below the vehicle body of a van or wagon type automobile. be.

Conventionally, as a spare tire support device for this type of automobile, a tire for mounting a spare tire whose front end is rotatably attached to the vehicle body, as disclosed in, for example, Japanese Utility Model Application Publication No. 56-70377, etc. The vehicle comprises a carrier, and a hook member rotatably attached to the vehicle body, the upper end of which corresponds to the rear end of the tire carrier, the rear end of the tire carrier being engaged with and held by the lower end of the hook member. What has been done is known.

However, in the above-mentioned conventional device, when removing the spare tire, the hook member is rotated outward while lifting the rear end of the tire carrier on which the spare tire is mounted with one hand, and the rear end of the tire carrier is engaged with the rear end of the tire carrier. There was a problem in that the state had to be released and the removal operation was troublesome.

The present invention has been developed in view of this point, and when the rear end of the tire carrier is lifted up when removing the spare tire, the hook member rotates outward in conjunction with this and engages the rear end of the tire carrier. The purpose of this is to release the condition so that the spare tire can be easily removed.

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

1 to 3 show a wagon-type automobile equipped with a spare tire support device A which is an embodiment of the present invention, in which 1 is a vehicle body, 2 is a back door attached to the back of the vehicle body 1 so as to be openable and closable, and 3 is a floor panel constituting the floor portion of the vehicle body 1, and on the lower rear side of the floor panel 3, a front end portion 5a of a tire carrier 5 for mounting a spare tire T is rotatably mounted via a bracket 4. Along with being installed,
A holding means 6 for holding the rear end 5b of the tire carrier 5 is provided corresponding to the rear end 5b of the tire carrier 5.

The holding means 6 includes a lock bolt 7 that extends from the upper surface of the floor panel 3 and hangs down from the upper side of the floor panel 3. On the outer periphery of the lower part of the lock bolt 7,
A cylindrical clamp member 8 having a threaded portion 8a on its inner circumferential surface is threadedly connected to the clamp member 8, and the clamp member 8 can be moved up and down by rotation of the lock bolt 7. At the lower end of the clamp member 8, a hook member 10 having a U-shaped cross section and opening forward is supported via a pin 9 so as to be rotatable in a vertical plane in the longitudinal direction of the vehicle body. A hook-shaped locking portion 10a that can engage with the rear end portion 5b of the tire carrier 5 is formed on the front side of the lower end of the hook member 10, and the lower end surface of the locking portion 10a is an inclined surface that slopes forward and upward. 1
0b.

Further, a rear end portion of a base plate 11 that projects forward is fixed to the lower end portion of the clamp member 8, and a substantially dogleg-shaped lever 13 is attached to the front portion of the base plate 11 via a pin 12 at its central portion. It is rotatably supported. One end 13a of the lever 13 is in contact with the hook member 10, while the other end 13b is extended to curve rearward in correspondence with the inclined surface 10b of the hook member 10, and extends rearward and downward. An inclined curved portion 13c is formed. As described above, when the rear end portion 5b of the tire carrier 5 is lifted when removing the spare tire T, the rear end portion 5b of the tire carrier 5 is moved to the lever 13.
The spare tire support device A of the present invention is configured such that the hook member 10 is rotated outwardly via the lever 13 by abutting on one end 13a of the lever 13.

In addition, 14 is a floor cross member fixed to the rear lower surface of the floor panel 3, and 15 is a floor cross member fixed to the rear lower surface of the floor panel 3.
The rear cross member 16 at the rear end is a point spring interposed between the base plate 11 and the lever 13, and the point spring 16 is interposed between the base plate 11 and the lever 13.
Normally, the lever 13 is urged to rotate inward (clockwise in Fig. 2), and when the lever 13 is rotated outward from a certain position (consideration point), the lever 13 is urged outward. This is to bias the rotation in the direction (counterclockwise in FIG. 2). Further, reference numeral 17 is a stopper integrally formed on the front end portion of the base plate 11, and serves to restrict forward rotation of the lever 13. 18 is a notch formed in the lever 13 to avoid interference with the pin 9 that supports the hook member 10, 19 is a stop ring, and 20 is a washer.

Next, the operation of the spare tire support device A will be explained with reference to FIGS. 1, 2, and 4.

Normally, when the spare tire T is supported as shown in FIG. 2, the rear end 5b of the tire carrier 5 is rotated in the tightening direction of the lock bolt 7.
is pulled upward via the clamp member 8 and the hook member 10, and the spare tire T placed on the tire carrier 5 is pressed against the floor cross member 14 on the lower side of the floor panel 3, so that the spare tire T is attached to the floor panel. 3 and the tire carrier 5.

When removing the spare tire T from such a situation, first rotate the lock bolt 7 in the loosening direction to lower the rear end 5b of the tire carrier 5, and then remove the space between the spare tire T and the floor cross member 14.
A space necessary for lifting the tire carrier 5 upward is secured.

Thereafter, when the rear end portion 5b of the tire carrier 5 is lifted upward, the rear end portion 5b of the tire carrier 5 comes into contact with one end portion 13a of the lever 13, thereby causing the lever 13 to release the tire carrier 5 from the rear end portion 5b. The pressing force causes the hook member 10 to rotate outward (counterclockwise) around the pin 12 against the inward biasing force of the consideration point spring 16, and the hook member 10 in contact with the lever 13 As the pin 9 rotates, it rotates outward around the pin 9. When the lever 13 is rotated outward from a certain position (consideration point), the biasing force of the contemplation point spring 16 changes outward, so that the lever 13 and the hook member 10 are rotated outwardly from a certain position (consideration point). As shown in FIG.
The upper end of the clamp member 8 is rotated until it comes into contact with the outer surface of the clamp member 8, and is held in that state.

In this state, when the rear end portion 5b of the tire carrier 5 is pulled down, the locking portion 1 of the hook member 10
Since 0a has moved outward from its original position,
The rear end portion 5b of the tire carrier 5 is connected to the locking portion 10a.
It will descend in front of it without engaging it.

Thereafter, as shown in FIG. 4b, the rear end portion 5b of the tire carrier 5 comes into contact with the curved portion 13c of the lever 13;
When b is pulled down, the lever 13 rotates inward (clockwise) around the pin 12 against the outward biasing force of the consideration point spring 16. Then, when the lever 13 is rotated inward from a certain position (thought point), the biasing force of the thought point spring 16 changes inward again. The base plate 11 rotates until it comes into contact with the stopper 17 of the base plate 11. Further, since the pressing force from the lever 13 is removed, the hook member 10 rotates inward around the pin 9 due to its own weight and returns to its original position. As a result, the rear end portion 5b of the tire carrier 5 is released from the engagement with the curved portion 13c of the lever 13 and descends, and by bringing the rear end portion 5b into contact with the ground,
As shown by the imaginary line in FIG. 1, the tire carrier 5 is tilted rearward and downward, and the spare tire T can be taken out from above the tire carrier 5.

On the other hand, when installing the spare tire T, after placing the spare tire T on the tire carrier 5 tilted rearward and downward as described above, the rear end portion 5b of the tire carrier 5 is lifted upward, as shown in FIG. c.
As shown in FIG. 2, the rear end portion 5b of the tire carrier 5 comes into sliding contact with the inclined surface 10b of the hook member 10, and as a result, the hook member 10 is rotated outward around the pin 9 due to the pressing force from the tire carrier 5. do.
Then, the rear end portion 5b of the tire carrier 5 is lifted by a predetermined amount and the inclined surface 10b of the hook member 10 is lifted.
When separated from the hook member 10, the hook member 10 pivots inward due to its own weight and returns to its original position. When the rear end portion 5b of the tire carrier 5 is lowered in this state, the rear end portion 5b of the tire carrier 5 is attached to the locking portion 10a of the hook member 10.
is engaged with and held.

Thereafter, the spare tire T is firmly held between the floor panel 3 and the tire carrier 5 by rotating the lock bolt 7 in the tightening direction and pulling up the rear end 5b of the tire carrier 5.

Incidentally, when removing or installing the spare tire T as described above, it is necessary to open the back door 2 in order to rotate the lock bolt 7.
This is a measure taken to prevent the spare tire T from being stolen.

Therefore, when removing or installing the spare tire T, simply lifting the rear end 5b of the tire carrier 5 engages the tire carrier 5 with the locking portion 10a of the hook member 10, or Since the engaged state can be released, the spare tire T can be easily and easily removed and installed even by just one person.
The operability can be improved.

Incidentally, in the above embodiment, the case where the present invention is applied to a wagon-type vehicle has been described, but it goes without saying that it can be similarly applied to a van-type vehicle or the like.

As explained above, according to the present invention, when the rear end of the tire carrier is lifted when removing the spare tire, the rear end of the tire carrier comes into contact with one end of the lever, and the hook member is removed via the lever. Since the engagement state with the hook member is released by rotating the tire carrier in the opposite direction, the spare tire can be easily removed by a simple operation of lifting the rear end of the tire carrier. Therefore, it is possible to improve the ease of removal.
