Description

  The present invention relates to a spare tire holding structure.

  Conventionally, a spare tire for a vehicle is generally accommodated in a luggage compartment at the rear of the passenger compartment, and the spare tire is held in a constant state when accommodated. As such a spare tire holding structure, for example, a structure is known in which a spare tire is held along a wall surface of a cargo compartment with a part of the outer peripheral surface thereof being downward (see Patent Document 1).

In this holding structure, a part of the outer peripheral surface of the spare tire is brought into contact with the slope of the rear wheel house that gradually inclines toward the center of the cargo compartment, and the spare tire is fixed to the wall surface of the cargo compartment with bolts. As a result, even if the spare tire has a different outer diameter, it can be dealt with by simply shifting the spare tire along the slope of the rear wheel house.
JP-A-8-40318

  However, in such a spare tire holding structure, when holding a spare tire having a large outer diameter, the spare tire is held while being shifted downward along the slope of the rear wheel house. For this reason, since the spare tire is closer to the center side of the cargo compartment, there is a problem that the area occupied by the spare tire is increased and the accommodation space in the cargo compartment is reduced.

  The present invention has been made in view of such a conventional problem, and provides a spare tire holding structure capable of preventing a storage space in a cargo compartment from being narrowed even if the outer diameter of the spare tire to be held is increased. For the purpose.

  In order to solve the above-mentioned problem, in the spare tire holding structure according to claim 1 of the present invention, the spare tire is provided in the cargo compartment of the vehicle body, and the spare tire is disposed in the cargo compartment in a state where a part of the outer peripheral surface faces downward. Mounting means for mounting along the wall surface, and fixing means provided on the wall surface of the cargo compartment facing the center of the hub hole of the spare tire mounted on the mounting means; A pressing means having an insertion hole facing the hub hole and pressing the inner side of the spare tire placed on the mounting means against the hub hole, and the pressing means holding the spare tire The insertion hole is inserted from the inside of the vehicle into the insertion hole and the center portion of the hub hole, and the holding means is sandwiched between the spare tire, and the insertion means is detachably fixed to the fixing means. In front of the holding means The insertion means include a central portion opposite to the position of the hub hole is set to one formed in a long hole extending in insertable straight in any position.

  In such a configuration, it is possible to hold the spare tire having a large outer diameter without moving by inserting the insertion means at an arbitrary position with the extending direction of the insertion hole of the pressing means being the vertical direction. An increase in the area occupied by the spare tire in the room can be suppressed.

  In the spare tire holding structure according to claim 2, the insertion hole is formed as a long hole extending linearly in one direction from a position facing the center of the hub hole of the pressing means. .

  In such a configuration, the length of the insertion hole can be shortened compared to the case where the insertion hole is formed to extend linearly across the position facing the center of the hub hole. The rigidity of the means can be maintained.

  As described above, in the spare tire holding structure according to claim 1 of the present invention, the outer diameter is large by inserting the insertion means at an arbitrary position with the extending direction of the insertion hole of the pressing means being the vertical direction. Since the spare tire can be held without being moved, it is possible to suppress an increase in the area occupied by the spare tire in the cargo compartment. Therefore, even if the outer diameter of the spare tire to be held increases, it is possible to prevent the accommodation space in the cargo compartment from being narrowed.

  In the spare tire holding structure according to claim 2, the length of the insertion hole is shorter than that in the case where the insertion hole is formed to extend linearly across the position facing the center portion of the hub hole. This makes it possible to maintain the rigidity of the pressing means. Therefore, the spare tire can be firmly held.

The insertion hole 42 is formed as a long hole that extends linearly downward from the position facing the center of the hub hole 124 at the center 41 so that the bolt 5 can be inserted into an arbitrary position.

  The holding plate 4 is provided with four holding holes 43 diagonally surrounding the insertion hole 42 for holding the holding plate 4.

  The bolt 5 is inserted from the inside of the vehicle into the insertion hole 42 of the holding plate 4 and the central part of the hub hole 124 of the spare tire 1, and the head 51 is inserted into the inner side surface 44 of the central part 41 via a washer 52. The tip 531 of the shaft 53 is screwed onto the nut 3 and is detachably fixed.

  Therefore, the pressing plate 4 is sandwiched between the bolt 5 and the spare tire 1 and is fixed to the left wall surface 101a of the luggage compartment 101 via the fixing member 20 in this state. As a result, the spare tire 1 is held while the central portion 123a is pressed against the left wall surface 101a by the pressing plate 4 from the inside of the vehicle while being mounted on the mounting table 2.

  In this configuration, as shown in FIG. 5, when holding the spare tire 100 having a larger outer diameter than the spare tire 1 of the present embodiment, after the spare tire 100 is mounted on the mounting table 2, the pressing plate 4 , The extending direction of the insertion hole 42 is set to the vertical direction, the direction of the insertion hole 42 is set to the lower side, the lower portion of the insertion hole 42 is aligned with the hole 31 of the nut 3, and the insertion position of the bolt 5 is set. Hold the tire 1. In this state, the bolt 5 is inserted into the insertion hole 42 and the hub hole 124 from the inside of the vehicle and screwed to the nut 3.

By inserting the bolt 5 into the lower portion of the insertion hole 42 in the vertical direction, the pair tire 100 having a large outer diameter can be held without being moved.

  For this reason, since the spare tire 100 does not approach the center side of the luggage compartment 101, an increase in the area occupied by the spare tire in the luggage compartment 101 can be suppressed. Therefore, in the spare tire holding structure of the present embodiment, it is possible to prevent the accommodation space in the luggage compartment 101 from being narrowed even if the outer diameter of the spare tire to be held is increased.

  Further, in the case of holding a spare tire 200 having an outer diameter smaller than that of the spare tire 1 of the present embodiment, after the spare tire 200 is mounted on the mounting table 2, the insertion hole 42 is extended with the holding plate 4. The present direction is set to the vertical direction and the direction of the insertion hole 42 is set to the upper side, and the upper portion of the insertion hole 42 is aligned with the hole 31 of the nut 3 to set the insertion position and press the spare tire. In this state, the bolt 5 is inserted into the insertion hole 42 of the holding plate 4 and the hub hole 124 of the spare tire 1 from the inside of the vehicle and screwed to the nut 3.

  Therefore, even if the outer diameters of the spare tires to be held are different, the spare tire can be held by changing the insertion position of the bolt 5 of the presser plate 4, so that the holding work can be easily performed. Therefore, it is possible to improve the holding workability for various types of spare tires having different outer diameters.

  Further, since the mounting table 2 mounts the spare tire 1 and supports the spare tire 1, the mounting table 2 receives the full load of the spare tire 1, so that the fixing member 20 is loaded. Avoided. Therefore, since the strength of the fixing member 20 can be reduced as compared with the case where the mounting table 2 is not used, the weight of the fixing member 20 can be reduced.

  Moreover, since the front and rear portions 212 and 213 are formed to extend obliquely upward and forward from the front and rear ends of the intermediate portion 211 in the mounting table main body 21, compared to the case where the entire mounting table main body 21 is formed horizontally. Thus, the support area of the spare tire 1 can be increased, and the spare tire 1 can be supported more stably. Therefore, the holding functionality of the spare tire 1 can be improved.

  In addition, if the extension angles of the front and rear portions 212 and 213 are set to be the same in the mounting table main body 21, the spare tire 1 can be mounted more stably. Therefore, positioning when mounting the spare tire 1 is performed. It can be made unnecessary.

  Further, the insertion hole 42 of the pressing plate 4 is formed so as to extend linearly in one direction from a position facing the central portion of the hub hole 124 in the pressing plate 4. For this reason, since it becomes possible to shorten the length of the insertion hole 42 as compared with the case where the insertion hole 42 is formed extending linearly across the position facing the central portion of the hub hole 124, The rigidity of the pressing plate 4 can be maintained. Therefore, the spare tire can be firmly held.

  In the present embodiment, the circular pressing plate 4 is used as the pressing means of the present invention, but a rectangular pressing plate may be used. Moreover, if the center part 123a of the spare tire 1 can be pressed down, the shape of a holding means will not be specifically limited.

  Further, the mounting table 2 is formed so that the spare tire 1 is placed in a standing state, but it is sufficient to place the spare tire 1 with a part of the outer peripheral surface 1a on the lower side. Depending on the structure in the luggage compartment 101, the spare tire 1 may be formed so as to be placed in a slightly inclined state.

  Further, although the spare tire 1 is placed with the disc 123 protruding to the inside of the vehicle, the spare tire 1 may be placed with the disc 123 protruding to the outside of the vehicle by changing the direction. In this case, since the distance between the hub hole 124 and the hole 31 of the nut 3 is shortened, the length of the bolt 5 is also shortened, so that the cost of the bolt 5 can be reduced and the bolt 5 can be easily attached. it can.
