Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support structure for a cage in a parking device for an automobile or a bicycle.

Bicycles have become rapidly popular these days, as they are non-polluting, fuel-free, and can be used for exercise. However, parking a large number of bicycles has become a major social problem, especially near stations, but public parking lots have not been developed due to difficulties in acquiring land, and private parking lots are not available to some extent in cities. Although there are some problems, many of them are extremely small-scale and far from a fundamental solution.

In order to solve this problem all at once, a three-dimensional bicycle parking system has been proposed that can effectively utilize a small area and is commercially viable.

That is, in this parking device, upper and lower sprocket wheels corresponding to each other are pivotally supported on at least two or more adjacent upper and lower sides of the four sides of a tower having a rectangular cross-section, and a chain is wound between them. Although the intended purpose was achieved by hanging cages for cars or bicycles at even intervals with arms extending from the chain, ,
In addition, even in the lifting position, due to the unbalanced load, there was a problem in that the lifting speed could not be increased due to severe lateral shaking during lateral movement, especially at the reversed positions at both the upper and lower ends. Furthermore, if the cage were to swing, it would not only be inconvenient to put in and take out the bicycle, but there was also the danger that the bicycle could fall and cause an accident that could result in injury or death.

Furthermore, although the popularity of car parking devices has been remarkable in recent years, this car storage cage is supported in two places on both sides and at the same position in the depth direction, and is rotatably supported at the top of the tower so that it can be reversed. Another drawback was that it oscillated during lifting and lowering operations, making it impossible to increase the lifting speed.

The object of the present invention is to solve the above-mentioned defects, and to provide a parking system that prevents the cage from swinging and allows smooth loading and unloading of automobiles, etc., and increases the speed of raising and lowering the cage, thereby preventing the risk of personal injury. The object of the present invention is to provide a support structure for a cage in an apparatus.

Hereinafter, an embodiment in which the first invention of the present application is embodied in a three-dimensional bicycle parking device will be explained with reference to the drawings. In the drawings, 1 is a square tube-shaped interior with a lid set upright on the ground S as shown in FIG. It is a tower, and the interior is used as a machine room. Reference numeral 2 denotes an outer tower in the form of a regular square frame, which is erected on the ground S so as to surround the outside of the tower 1 at regular intervals, and has four pillars 3a to 3d located on an extension of the diagonal line of the inner tower 1.
The structure is constructed by four upper and lower horizontal frames 4a to 4d installed between each of the pillars 3a to 3d.

Note that this outer tower 2 is provided with a reinforcing frame (not shown), decorative boards are provided on the four sides, and a connecting frame (not shown) is attached between the two tallows 1 and 2. .

Reference numeral 5 indicates a first upper sprocket wheel pivotally supported on the outside of the upper part of the inner tower 1, as shown in FIG. 2, and reference numeral 6 corresponds to the first upper sprocket wheel 5, as shown in FIG. A first chain 7 is hung between the first lower sprocket wheel 5 and the first upper sprocket wheel 5, which are pivotally supported on the outside of the lower part of the inner tower 1.

Reference numeral 8 denotes a second upper sprocket wheel that is pivotally supported on each horizontal frame 4c of the outer tower 2 at a position near the respective end, and both of them are at the same height as the first upper sprocket wheel 5 and have the same sprocket wheel. It is located a certain distance away from the wheel 5 in its diametrical direction. Reference numeral 9 denotes a second lower sprocket wheel that is pivotally supported by each horizontal frame 4d so as to correspond to the second upper sprocket wheel 8, and is at the same height as the first lower sprocket wheel 6. It is located a certain distance away from the sprocket wheel 6 in its diametrical direction. Reference numeral 10 denotes a second chain suspended between the second upper and lower sprocket wheels 8 and 9.

The second chain 10 and the first chain 7 are rotated synchronously with each other by a drive mechanism 41 in the inner tower 1 via the upper sprocket wheels 5,8.

As shown in FIGS. 1 and 3, reference numeral 11 is a V-shaped shaft-shaped first support arm fixed to the first chain 7 at equal pitches, and the tip thereof is located at the center on the upper surface of one side of the bicycle storage cage 13. It is rotatably fixed to a guide rod 16 that protrudes outward (to the right in FIG. 3) from a slightly forward position. Reference numeral 14 denotes second support arms having a horizontal V shape fixed to the second chain 10 at equal pitches, and their lower ends extend outward from a position slightly rearward from the center on the upper surface of the other side of the cage 13. It is rotatably fixed to a guide rod 16 that protrudes toward the left side in FIG. 3. This first,
The second support arms 11, 14 project outward from the chains 7, 10 in the same diametrical direction of the sprocket wheels 5, 6, 8, 9. or,
The accommodation cage 13 is suspended and supported so as to be located between the chains 7 and 10 and always in a horizontal state.

Reference numeral 18 denotes a guide roller which is freely rotatably attached to the tip of each of the arms 11 and 14, as shown in FIG. Reference numeral 17 denotes a plurality of semicircular arc-shaped guide rails provided above the upper sprocket wheels 5 and 8 and below the lower sprocket wheels 6 and 9, and when each cage 13 is reversed in the vertical direction. In the arms 11, 14
A guide roller 18 at the tip is guided to minimize swinging of each chain 7, 10 in the axial direction of the sprocket wheel.

By the way, as shown in FIG. 2, among the large number of cages 13 arranged in the first and second chains 7 and 10, the one that goes up and down on the outside of the inner tower 1 is located right next to the inner tower 1. The other cage 13 is located on the diagonal extension of the inner tower 1 and is adjacent to the cage 13 directly beside the inner tower 1, forming a total of eight cage rows arranged vertically.

Next, the structure of the bicycle storage cage 13 will be explained with reference to FIG. 4. 29 has a U-shaped groove disposed on the bottom surface of the case 13 in a diagonal shape that goes downward toward the side opposite to the entrance 13a and parallel to each other. Of the four guide frames, the second and fourth guide frames 29' from the left side have small slopes. 30 is a support frame horizontally arranged in upper and lower stages inside the cage 13; 31 is a front wheel holding frame made of two rods connected between the support frames 30; each of the guide frames 29, 29; ′ are provided at equal pitches. 32 is the second and fourth guide frame 2
9' and the front wheel holding frame 31 are formed of a pair of rods connected diagonally to the front wheel holding frame 31.

Of the four guide frames 29, 29', the slope of the guide frame 29' is made smaller and its tip is raised so that the ends of the handlebars of adjacent bicycles can be arranged so as to overlap each other vertically, thereby saving space in a narrow space. This is to enable effective use of the information.

Now, in the embodiment of the first invention of the present application, the third
As shown in the figure, a pair of first and second support arms 1 are provided for a pair of first and second chains 7 and 10 that are shifted back and forth.
1 and 14 are fixed, and the arms 11 and 14 suspend and support the front and rear positions of the upper surface of each cage 13, so that the cage 13 cannot be swung in the front-back and left-right directions. Therefore, it is possible to smoothly put in and take out the bicycle, and the risk of personal injury or the like can be eliminated.

Furthermore, in the embodiment described above, a guide rail 17 is provided at the location where each cage 13 is reversed, so that the cage 13 can swing in the direction of the axis of the sprocket wheels 5, 6, 8, and 9. Even in this case, each guide roller 18 contacts the inner wall of the guide rail 17. Therefore, the cage 13 can be prevented from swinging more reliably.

In the above embodiment, the cage 13 was supported at its front and rear positions, but as shown in FIG. Alternatively, as shown in FIG. 6, the cage 13 may be located at positions offset from each other in the left and right width directions on both the front and rear sides.

In addition, in the embodiment shown in FIG.
2, 15 are rotatably attached, each hanging member 12,
The lower end of 15 is fixed to cage 13.

Next, an embodiment embodying the second invention of the present application will be explained with reference to FIGS. 7 and 10 are shifted vertically from each other.

That is, in this embodiment, the height of the first chain 7 is lower than that of the second chain 10, and the first support arm 11 attached on the first chain 7
The distal end of the second support arm 14 attached to the first and second chains 10 is fixed to the upper side surface of the cage 13.

In this way, each cage 13 is supported by the support arms 11 and 14 at a front position and a rear position, respectively, and since these positions are vertically shifted from each other, the cages 13 are supported in the front-rear direction and left-right direction. The swinging of the can be further reliably prevented.

In this embodiment, the cage 13 is supported at both its upper and lower surfaces, but the pair of support arms 11,
14 may be supported at an intermediate position within a range where they are not in the same phase.

As described above, the present invention can prevent the car or bicycle storage cage from swinging, and as a result, the car or bicycle can be taken in and out smoothly, and the cage can be raised and lowered at an increased speed, thereby preventing accidents resulting in injury or death. It is effective in preventing the dangers of
