Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support structure for a cage in a parking device for a car or 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 local cities. Although there are 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 are respectively pivotally supported on the upper and lower ends of at least two or more adjacent sides of the four sides of a tower having a rectangular cross-section, and a chain is placed between them. It was constructed by suspending a car or bicycle storage cage at even intervals with the arms hanging from the chain, and was able to achieve the intended purpose, but it was difficult to suspend the cage from a single arm. Because
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 personal injury.

Furthermore, although the popularity of car parking devices has been remarkable in recent years, this car storage cage is rotatably supported in two places on both sides at the top of the tower so that it can be turned over, so it still swings when moving up and down. However, there was a flaw in that the lifting speed could not be increased.

The purpose of this invention is to eliminate the above-mentioned defects, to prevent the cage from swinging, to allow smooth loading and unloading of cars, etc., and to increase 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 present invention is embodied in a three-dimensional bicycle parking device will be explained with reference to the drawings.
is an inner tower in the shape of a square cylinder with a lid that stands on the ground S, and the inside 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,
It is constructed of four pillars 3a to 3d located on the diagonal extension of the inner tower 1 and four horizontal frames 4a to 4d installed between the pillars 3a to 3d, respectively. It should be noted that this outer tower 2 is provided with a reinforcing frame (not shown), a decorative board is placed on the four sides, and a connecting frame (not shown) is attached between the two towers 1 and 2. There is.

Reference numeral 5 denotes a first upper sprocket wheel pivotally supported at the four upper corners of the inner tower 1, and reference numeral 6 denotes a first upper sprocket wheel pivotally supported at the lower four corners of the inner tower 1 so as to correspond to the first upper sprocket wheel 5. A first chain 7 is hung between the lower sprocket wheel and the first upper sprocket wheel 5, respectively.

8 is a second upper sprocket wheel pivotally supported on the horizontal frame 4c of the outer tower 2 so as to correspond to the first upper sprocket wheel 5;
It is located above the first upper sprocket wheel 5 by a certain distance L. 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 located a certain distance L from the first lower sprocket wheel 6. It is located above. A second chain 10 is wound around the second upper and lower sprocket wheels 8 and 9.

Reference numeral 11 denotes a horizontal V-shaped first support arm fixed to the first chain 7 at equal pitches. It is rotatably fixed to a guide rod 33 that protrudes toward one side. 1
Reference numeral 4 denotes second support arms in the shape of a horizontal V that are fixed to the second chain 10 at equal pitches, and their tips extend outward from the center of the upper edge of the other side of the cage 13 (in FIG. 3). It is rotatably fixed to a guide rod 33 that protrudes toward the left side. The first and second support arms 11 and 14 are connected to the first and second upper (lower) sprocket wheels 5,
8 (6, 9) (height difference in mounting position between first upper sprocket wheel 5 and second upper sprocket wheel 8 and first lower sprocket wheel 6 and second lower sprocket wheel 9) (meaning the difference in height between the mounting positions).
As shown in FIG. 3, the cage 13 is moved above the upper sprocket wheels 5, 8 (in a state parallel to the ground S) so that the cage 13 can be reversed.

34 is a guide roller which is freely rotatably attached to the tip of each arm 11, 14, as shown in FIG. 35 are upper and lower sprocket wheels 6,
A plurality of semi-circular guide rails provided below the cage 9 (that is, at the inverted position of the cage 13), which guide the ends of the arms 11 and 14 when the cage 13 is inverted in the vertical direction. The rollers 34 are guided to minimize swinging of each chain 7, 10 in the axial direction of the sprocket wheel. All of these guide rails 35 have a channel-shaped cross section, and the upper guide rail 35 has an opening facing downward, and the lower guide rail 35 has an opening facing upward. (In addition, the guide rail 35 has a channel shape in cross section with standing walls on both sides,
It may also be L-shaped in cross section with a standing wall on only one side. ) By the way, as shown in FIG. 2, among the many cages 13 arranged in the first and second chains 7 and 10, the one that goes up and down outside the inner tower 1 is located right next to the inner tower 1. , (flip that cage 13
Eight cage rows are formed such that the other cage 13 (moved to the position) is located on the inner tower 1 (at the portion facing the corner).

Next, one of the four sets of drive mechanisms for independently raising and lowering the cages 13 disposed in the four sets of first and second chains 7 and 10 will be explained. It is a geared motor installed on the top surface, and a sprocket wheel 17 is fixed to its rotating shaft. 18 is a support shaft supported by a bearing 19 fixed to the upper part of the inner tower 1 and a bearing 20 fixed to the horizontal frame 4b of the outer tower 2;
1, 22, and 23 are sprocket wheels fixed to the support shaft 18 so as to correspond to the sprocket wheel 17 and the first and second chains 7, 10, respectively; and 24 are sprocket wheels 17, 21.
The chains 25 and 26 that are wound around the sprocket wheels 2 are fixed to a common shaft with the first and second upper sprocket wheels 5 and 8, respectively.
7, 28 and the sprocket wheels 22, 2
This is a chain that is wound between 3 and 3.

Therefore, when the sprocket wheel 17 of the geared motor 16 is rotated, the sprocket wheel 21, the spindle 18, and the sprocket wheels 22 and 23 are rotated through the chain 24, and the sprocket wheels are also rotated through the chains 25 and 26. The first upper sprocket wheel 5 and the second upper sprocket wheel 8 are rotated, the first and second chains 7 and 10 are rotated synchronously, and the cage 13 is moved up and down.

Next, the structure of the car storage cage 13 will be explained with reference to FIG. 4. 29 is a U-shaped groove disposed on the bottom surface of the cage 13 in a diagonal shape that descends toward the opposite side of the entrance/exit 13a and parallel to each other. Among the four guide frames, the second and fourth guide frames 29' from the left side have a small slope. Reference numeral 30 denotes a support frame arranged horizontally in two stages, upper and lower, 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, the front wheel holding frame is made 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 the tip thereof is made higher. The handlebars of the bicycles arranged in the guide frame 29 are on the bottom, and the handlebars of the bicycles arranged in the second and fourth guide frames 29' are on the top, so that narrow spaces can be avoided. This is to enable effective use of the information.

Now, in the embodiment of the present invention, a pair of first,
First and second support arms 11 and 14 are fixed to the second chains 7 and 10 at different positions above and below, and the lower and upper parts of the cage 13 are suspended and supported by the arms 11 and 14, respectively. Therefore, it is possible to prevent the cage 13 from swinging back and forth and in the left and right directions, so that the bicycle can be taken in and out smoothly, and the risk of personal injury or the like can be eliminated.

Furthermore, in the embodiment described above, a guide rail 35 for guiding the cage 13 via a guide roller 34 is provided at the location where each cage 13 is reversed, so that the cage 13 is aligned with the axis of the sprocket wheels 5, 6, 8, and 9. Even when attempting to swing in the center direction, each guide roller 34 contacts the inner wall of the guide rail 35. Therefore, the cage 13 can be prevented from swinging more reliably. Furthermore, since the guide rail 35 is provided only at the inverted position of the cage 13, the guide rail 35 can be made shorter compared to the case where it is provided on the entire trajectory of the cage 13, and the materials required for this can be saved, resulting in the manufacturing cost of the entire parking device. can also be reduced.

In the embodiment described above, the cage 13 is supported at its upper and lower sides, but the pair of first and second support arms 11 and 14 may be provided at an intermediate position within a range where they are not in the same phase. Also, both arms 11,1
4 is supported by cage 1 as shown in FIG.
The cage 13 may be located at a position shifted forward or backward on the cage 13, or may be located at both the front and rear corners of the cage 13.

In the embodiments shown in FIGS. 1 to 5, the positions of the pair of chains 7 and 10 are shifted vertically from each other, but both chains 7 and 10 are supported at the same height as shown in FIG. Only the upper part of the cage 13 may be supported by the arms 11 and 14. Moreover, the support arm 1 for the cage 13
1 and 14 may be attached to both the front and rear corners of the cage 13, as shown in FIG.

In the embodiment shown in FIGS. 6 and 7, each pair of guide rails 35 are also provided at the same height.

As described above, the present invention can prevent the car or bicycle storage cage from swinging, and as a result, it is possible to smoothly put in and take out cars, etc., and increase the speed of raising and lowering the cage, which can lead to accidents resulting in injury or death. In addition, guide rails are provided only at the reversed position of the cage, so
The guide rail 35 can be shortened, the materials required for it can be saved, and the manufacturing cost of the entire parking device can be reduced.
