Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a spare tire board fixing structure for an automobile, and more particularly to a structure capable of fixing and supporting a spare tire board at different height positions. is there.

[Conventional technology]

Normally, in a passenger car, spare tires are housed in a trunk room at the rear of the vehicle body, so that a spare tire housing space is provided in the trunk room.

FIG. 4 (a) is an overall view of a conventional passenger car in which a spare tire storage space is secured in the trunk room,
4 (b) and 5 are a plan view and a sectional view showing the inside of the trunk room. In the figure, reference numeral 2 is a trunk room formed in the rear part of the vehicle body 1, and a concave portion 4 as a spare tire storage space is formed in the center of a floor panel 3 of the trunk room 2. A spare tire 5 is housed in the concave portion 4, a spare tire board 6 is placed on the concave portion 4 to flatten the floor surface,
We are trying to improve cargo handling. The spare tire 5 is
It is designed to be more compact than the normal running tire 8 from the viewpoint of effective use of the luggage compartment.

A locking pin 6a is provided on the rear edge of the rear surface of the spare tire board 6.
The spare tire board 6 is positioned and fixed by inserting the locking pin 6a into the engagement hole 7a of the bracket 7 attached to the side wall of the concave portion 4 of the vehicle body.

When the normal traveling tire 8 is punctured during traveling, the defective traveling tire 8 replaced with the spare tire 5 can be temporarily stored in the concave portion 4. .

[Problems to be solved by the invention]

However, when the traveling tire 8 is housed in the recessed portion 4, the traveling tire 8 is larger than the spare tire 5 as described above, and therefore the spare tire board 6 is indicated by a chain double-dashed line in FIG. As shown in the figure, it will be slightly raised compared to when the spare tire is stored. In this case, the locking pin 6a comes out of the engagement hole 7a of the bracket 7 on the vehicle body side, and the spare tire board 6 is displaced due to vibration during traveling. If the spare tire board 6 is displaced in this way, the luggage Y placed on the spare tire board 6 may tilt or fall over.

Further, in order to cope with such a change in tire size, two brackets 7 should be attached in advance at positions corresponding to spare tires and running tires, or the above-mentioned locking as shown in FIG. 5 (b). The length of the pin 6a needs to be extremely long.

However, attaching two brackets depending on the tire size has the problem of increasing the number of parts, and if the locking pin 6a is lengthened, the engagement hole of the bracket 7
7a can be engaged, but when the luggage Y is placed on the front end of the spare tire board 6 as shown by the chain double-dashed line in FIG. Irrespective of whether or not the above countermeasure is taken, the rear end portion of the spare tire board 6 is lifted. In this case, there is a problem that not only the luggage Y is tilted, but also abnormal noise is generated and a carpet (not shown) in the luggage compartment 2 is rolled up.

The present invention has been made in order to solve such a problem. Even when a tire having a larger outer dimension than a spare tire such as a traveling tire is stored in the storage portion of the spare tire, the cover of the storage portion is stored. It is an object of the present invention to obtain a spare tire board fixing structure for an automobile capable of reliably positioning and fixing the spare tire board.

[Means for solving problems]

A spare tire board fixing structure for an automobile according to the present invention has a bent portion formed at a lower end portion of a bracket member and an engagement hole formed at an edge portion of the spare tire board.
The bracket member is attached to the vertical wall of the trunk room so that the vertical position can be adjusted, and the bent portion is inserted into the engaging hole from above the spare tire board.

[Action]

In this invention, since the bracket member for positioning and fixing the spare tire board is attached to the vertical wall of the trunk room so that the vertical position can be adjusted, even if a tire larger than the spare tire is stored in the spare tire storage portion, It can be positioned reliably.

Further, since the bent portion is formed at the lower end of the bracket member and the bent portion is inserted into the engaging hole from above the spare tire board, when the rear end side of the spare tire board tries to float, The upper surface of the spare tire board comes into contact with the middle portion. Therefore, even when luggage is placed on the front portion of the spare tire board while the traveling tire is stored, the rear portion of the spare tire board does not float up. Further, since it is possible to accommodate either the spare tire or the running tire with the single bracket member, it is economical without increasing the number of parts.

〔Example〕

 An embodiment of this invention will be described below with reference to the drawings.

1 and 2 are views for explaining a spare tire board fixing structure for an automobile according to an embodiment of the present invention.
FIG. 1 (a) is a sectional view showing a spare tire in a retracted state and a traveling tire in a retracted state, and FIG. 1 (b) is a state in which the traveling tire is in a retracted state and loads are loaded on a front portion of the spare tire board. FIG. 2 (a) is a cross-sectional view showing a case where the spare tire board is fixed, and FIG. 2 (b) is a perspective view showing a fixing bracket for the spare tire board.
FIG. 2B is a sectional view taken along line IIb-IIb of FIG. In the figure, the same reference numerals as those in FIGS. 4 and 5 indicate the same or corresponding portions. Also in this embodiment, the spare tire 5 is stored in the recess 9 formed in the center of the trunk 2, and the spare tire board 10 is disposed on the recess 9. Here, a horizontal receiving portion 9a for receiving the rear end edge of the spare tire board 10 is formed on the upper rear end side of the spare tire housing concave portion 9. An engaging hole 10a is formed at the rear end of the spare tire board 10.

A bracket 11 for positioning and fixing the spare tire board 10 is provided on the rear vertical wall 2a of the trunk room 2. A long hole is provided on the top of the positioning bracket 11.
11a is formed, and this elongated hole 11a portion is fastened and fixed to the rear vertical wall 2a by a thumbscrew 12a and a nut 12b welded to the outer surface of the rear vertical wall 2a. Thereby, the height position of the bracket 11 can be adjusted. Further, guide grooves 11d are formed on both sides of the bracket 11, and the grooves 11d are fitted with the guide protrusions 2b formed on the rear vertical wall 2a. Further above bracket 11
A bent portion 11b having a V shape in a side view is formed at the lower end portion of the bent portion 11b. Faces the rear end edge of the spare tire board 10.

Next, the function and effect of this embodiment will be described.

When replacing a running tire 8 that has become unusable due to a flat tire or the like with a spare tire 5, first lift up the front portion of the spare tire board 10 and insert the engaging hole 10a at the rear end into the bracket 11
The spare tire board 10 is removed by removing the spare tire board 10 from the tip 11c. After that, the spare tire 5 is taken out from the concave portion 9, and the unusable running tire 8 is placed in the concave portion 9. In this state, by loosening the thumbscrew 12a, the bracket 11 is temporarily fixed at the upper position. Then, the spare tire board 10 is covered, and this time, the bracket 11 is aligned so that the tip portion 11c thereof is sufficiently inserted into the engaging hole 10a of the spare tire board 10, and the thumbscrew is positioned at this position.

As described above, in the spare tire board fixing structure of the present embodiment, the bracket 11 for positioning and fixing the spare tire board 10 is attached to the rear vertical wall 2a of the trunk room 2 so that the vertical position can be adjusted. Even when the traveling tire 8 larger than the spare tire 5 is stored in the storage portion, the spare tire board 10 can be reliably positioned.

Further, since the V-shaped bent portion 11b is formed in the lower portion of the bracket 11 and the inclined surface portion 11e of the bent portion 11b is opposed to the rear end surface of the spare tire board, the rear portion of the spare tire board 10 tries to float up. It comes into contact with the inclined surface portion 11e. This can prevent the rear portion of the spare tire board 10 from floating when the luggage is placed on the front portion thereof. Further, since it is possible to accommodate either the spare tire 5 or the traveling tire 8 with the bracket 11 alone, there is no increase in the number of parts and it is economical.

In the above embodiment, the bracket 11 is mounted on the vehicle body side so that the position can be adjusted by the thumbscrew 12a and the nut 12b, but the mounting mechanism of the bracket 11 on the vehicle body side is not limited to this.
