Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a method of storing replacement tires or the like under the floor or under the floor so as not to disturb daily use of a vehicle. The present invention relates to a tire storage device designed so that it can be easily pushed up to a ground level or a floor level by using a rotary tool used for the tire.

[0002]

2. Description of the Related Art Tires for automobiles are designed differently depending on running conditions, and are used for mud, rain, snow and the like. Therefore, even if a tire having a different application is used, not only does it not exert sufficient performance, but it is dangerous. In snowy regions, at least two types of tires, that is, so-called ordinary tires and snow tires belonging to the all-season type are required.

[0003] As a result, depending on the time, one of the four
It is necessary to secure a place to store book tires. It is based on such a requirement that a shelf plate is laid horizontally on a shed portion of a wooden garage and tires are mounted on the shelf plate for stocking. However, in recent years, prefabricated garages having a low ceiling height and cantilever open garages have become mainstream, and in such garages, it is also difficult to use a ceiling space. Therefore, it has been proposed to use the underground or under the floor (for example, see Japanese Patent Application Laid-Open No. 10-82194).

[0004] The tire storage disclosed in the publication comprises a box buried underground or the like in order to secure a space under the floor or under the floor, and a sturdy lid closing the opening of the box. After the tires are housed inside, the lid is attached, so that the upper part of the box is used as an empty space.

[0005]

Therefore, when the tire storage is used, the work to be performed is to lift the four tires from the underground level, replace the tires, and remove the four tires removed from the vehicle. It is the contents of work to put down in the box. In other words, it is the content of work that squats deeply and handles heavy objects.
Therefore, it can be conveniently used as far as a light vehicle tire is concerned. However, in the case of a large tire such as a 4WD vehicle or a tire of a large vehicle, there is a problem that it is practically difficult to use it alone. .

Accordingly, an object of the present invention is to solve a problem related to storage of a conventional underground or underfloor tire, and to provide a rotary tool that uses tire removal work and storage work for tire replacement regardless of the size and weight of the tire. It is an object of the present invention to provide a tire storage device that can be easily used alone by diverting, and for example, greatly expands the range of available vehicles except for special vehicles for heavy work.

[0007]

The present invention employs the following structure as means for achieving this object.

According to a first aspect of the present invention, there is provided a tire storage device, comprising: a base plate in a horizontal posture; a side frame having a feed screw shaft in a vertical direction and standing upright on a side of the base plate; A pallet having a nut member screwed to a feed screw shaft and supported in a horizontal position above a base plate via a pair of lifter arms; and a tire storage member mounted on the pallet for storing tires, The shaft has an engaging portion at an upper end thereof for enabling connection with a rotary tool, and each lifter arm has one end swingably connected to a side frame side of a base plate and a side frame side of a pallet, respectively. The pallet consists of a pair of arms with crossed sections and connected to each other, and a rolling roller attached to the other end. Together support, characterized by supporting the opposite side of the side frame by the rolling roller lifter arm.

In this configuration, the engaging portion at the upper end of the feed screw shaft is driven to rotate from the ground or above the floor using a rotary tool such as an electric drill used for tire replacement. When the feed screw shaft rotates, the side frame side of the pallet is screwed upward or downward via a nut member screwed to the feed screw shaft. Then, the interval between the pallet and the base plate changes, and the interval between the ends of the pair of arms connected to the pallet and the base plate changes. In addition, since the pair of arms form a lifter arm with an intermediate portion connected to be extendable and contractible, the arm supports the other end of the pair of arms, that is, the opposite side of the pallet via the rolling rollers. The distance between the side ends also changes in the same direction. As a result, for example, when the side frame side of the pallet is driven upward, the opposite side of the pallet is also driven upward by the lifter arm. Such an operation is the same when the pallet is driven in the descending direction. In the end, the pallet moves up and down while maintaining the horizontal posture by rotating the feed screw shaft.

According to a second aspect of the present invention, in the tire storage device, the tire storage member mounted on the pallet includes a bottom plate formed so as to form a shallow valley along the longitudinal direction of the pallet, and a valley on the bottom plate. And a partition plate for partitioning a plurality of storage spaces on a bottom plate, and tires are stood and stored side by side in the plurality of storage spaces.

The valley-shaped bottom plate prevents the stored tire from rolling, and the partition plate prevents the tire from falling down. Further, since the plurality of stored tires are located at the same horizontal position in a side-by-side state, the vertical position of the pallet can be adjusted only once in the tire removing operation or the storing operation.

According to a third aspect of the present invention, there is provided a tire storage device in which an operating rod having a locking member attached at two positions, that is, an upper limit and a lower limit of a pallet, is vertically movable on a side frame along a feed screw axis. And an indicator for operating the operating rod with the pallet via a latching member when the pallet exceeds the ascending or descending limit.

The operating rod of the indicator is linked to the pallet only when the pallet is at or above the lower limit or at the lower limit. That is, a region between the two hook members of the operating rod constitutes a non-operating region. The presence of the non-operating region makes it possible to detect that the pallet has exceeded the upper limit or the lower limit without greatly protruding the operating rod to the underground side or the ground side.

According to a fourth aspect of the present invention, there is provided a tire storage device including an outer case with a cover plate embedded under the ground or under the floor.

By installing the outer case underground or under the floor, it is possible to form a storage room under the floor or under the floor, which is shielded from the outside, without forming a concrete wall or a plate wall. In addition, the cover plate enables utilization of the space on the outer case.

In this case, when the feed screw shaft 23 is rotated clockwise by the rotating tool E connected using the engaging portion 23a at the upper end, the side frame 20 side of the pallet 30 is raised, and the base plate 10 and the pallet 3
The interval between zeros increases. Then, the lifter arm 40 is operated, and the interval between the ends of the arms 41, 41 constituting the lifter arm 40 on the side frame 20 side is enlarged. At this time, the distance between the other ends of the arms 41, 41 located on the opposite side of the side frame 20 with the intermediate shaft 42 interposed therebetween, that is, the interval between the ends provided with the rolling rollers 45, 45 , 45 and the same size as the side frame 20 side while enlarging. Therefore, by rotating the feed screw shaft 23, the pallet 30 moves up while maintaining the horizontal posture. Here, the pallet 30 is stopped when the guide portion 51a of the bottom plate 51 of the tire storage member 50 reaches the ground surface level GL. The tires T, T ... can be rolled and moved on the ground surface and rolled into the tire storage member 50 via the guide portion 51a. The partition plates 52, 52,... Can maintain the tires T, T,.

The tires T loaded in the tire storage member 50,
T are stored underground by rotating the rotary tool E in the reverse direction and lowering the pallet 30 (FIG. 7). Therefore, if a suitable cover plate is attached to the step G3 formed on the upper end surfaces of the wall surfaces G2 and G2, the ground portion can be effectively used.

The stoppers 11b, 1 of the base plate 10
1b determines the ascending and descending limits of the pallet 30 by mechanically restricting the rolling operation range of the rolling rollers 45, 45 (FIGS. 6 and 7). The backup function of the stoppers 11b and 11b is in charge by making it possible to visually confirm the limit and the lower limit (FIGS. 3 and 8). In other words, a pair of hook members 2 attached to the operating rod 24b of the indicator 24
