Description

  The present invention relates to a bicycle storage device. More specifically, the present invention can reduce sound generated during operation, and can store a large number of bicycles in a narrow space. More particularly, the present invention relates to a bicycle storage device in which a bicycle can be taken in and out, the movement of the device is stable, and maintenance is easy.

  In recent years, traffic problems caused by neglected bicycles have become a major social issue. In places where many bicycles are parked, such as railway stations and apartment buildings, bicycle storage devices are installed to park many bicycles in a small space. It is often done.

As a bicycle storage device that can park a large number of bicycles in a narrow space, there is a bicycle storage device in which a bicycle mounting table is movable along a rail and alternately shifted back and forth (the following patent document) 1 and 2).
Such a bicycle storage device can store the bicycles at a narrow interval because the handles of the adjacent bicycles do not interfere with each other, and can move the bicycle mounting table along the rail to put in and out the bicycle. Therefore, it is relatively easy to put in and out the bicycle.

However, the bicycle storage devices disclosed in Patent Documents 1 and 2 have the following drawbacks.
First, when the mounting table is moved to put in and out the bicycle, the metal angle members strongly collide each time, and a loud sound is generated by the impact at the time of the collision. For this reason, nearby residents sometimes feel the sound unpleasant as noise. In addition, the device and the bicycle may be damaged by the impact.
In addition, as is apparent from FIG. 4, the apparatus disclosed in Patent Document 1 has a bicycle mounting table (base) placed on the base member and in a position that is high above the floor surface. A relatively large force is required for the loading work, and it may be difficult for a lazy woman, a child, an elderly person, and the like to store.
In addition, two types of rollers, a horizontal roller and a vertical roller, are attached to the angle member that is fixed below the mounting table and moves along the rail, and these two types of rollers are provided on the inside and outside of the rail, respectively. Because of its location, inspections and repairs require work from both the inside and outside of the rail, and the rail shape is complex and the number of parts is high, making maintenance and assembly work very easy. It was bad.
Further, since each roller is in contact with the rail surface at only one point, the roller sometimes floats from the rail surface during traveling, and traveling stability is poor.

Similar to the device disclosed in Patent Document 2, the device disclosed in Patent Document 2 causes the metal moving carts to strongly collide with each other when the mounting table is moved to put in and out the bicycle. However, there is a problem that the device and the bicycle may be damaged due to noise damage or the impact at the time of collision.
In addition, since the upper roller and the lower roller of the movable carriage that are fixed below the mounting table and move along the rail are mounted side by side in the vertical direction, the mounting height of the mounting table is the sum of the diameters of at least two rollers. Therefore, the mounting table cannot be provided at a low position below a certain height from the floor surface.
In addition, since both the upper and lower rollers roll along the horizontal plane of the rail, it is possible to prevent vertical movement during running, but it is difficult to prevent horizontal movement (in the direction perpendicular to the rail) and stable. There was a case that it was not possible to run.
In addition, since the rollers are arranged in a substantially closed space inside the rail, there is a problem that it is difficult to check and repair when an abnormality occurs in traveling.

In front of the bicycle mount (2) (to the left in the drawing), the front position of the front wheel of the bicycle is regulated, and the front wheel is sandwiched from the left and right above the side plate (22) so as to prevent the bicycle from falling down. The regulating member (23) is provided.

The bicycle mounting table (2) is composed of a front mounting table (2a) installed on the front side of the guide rail (1) and a rear mounting table (2b) installed on the rear side. The front mounting table (2a) and the rear mounting table (2b) are provided so as to be alternately adjacent to each other.
Thereby, interference between the handles of adjacent bicycles is prevented, bicycles can be accommodated at a narrow interval, and a large number of bicycles can be accommodated in a small space.

In the present invention, both the front mounting table (2a) and the rear mounting table (2b) may be arranged almost horizontally, or only the front mounting table (2a) is moved forward as shown in FIG. 1 (b). You may incline and arrange | position so that it may become a high position.
When only the front mounting table (2a) is tilted so as to be in a high position toward the front, interference between the handles of adjacent bicycles can be prevented more reliably, and the interval between the bicycles is made narrower. It becomes possible.

A moving carriage (3) is attached below the bicycle placing table (2) (see FIG. 2).
The movable carriage (3) is fixed to the front side position and the rear side position of the bicycle mounting table (2), respectively, and moves along the guide rail (1) integrally with the bicycle mounting table (2).
The movable carriage (3) includes a hollow cylindrical carriage body (31) and a roller that is attached to the carriage body (31) and rolls while contacting the guide rail (1). Since the roller is omitted in FIG. 2, the configuration of the roller will be described below with reference to FIG.

FIG. 3 is a cross-sectional view showing the positional relationship between the guide rail (1) and the movable carriage (3).
The carriage main body (31) of the movable carriage (3) is formed of a short member having a regular rectangular tube shape (see FIGS. 3 and 2 (a)), and a first roller (4) is attached to one side surface of the carriage main body (31). A second roller (5) is attached. That is, the first roller (4) and the second roller (5) are in a positional relationship in which the rotation axes are orthogonal to each other and the second roller (5) is below the first roller (4).

  As described above, the second roller (5) rotating in the horizontal plane is disposed below the first roller (4) rotating in the vertical plane, so that as shown in FIG. 4) and the second roller (5) can be rolled at a position near the same direction side (inward side) of the guide rail (1). As a result, stable running can be obtained, and maintenance becomes very easy.

Elastic members (6) are attached to both end faces of the moving carriage (3) in the moving direction (length direction) (see FIG. 2).
When the user of the bicycle storage device moves the bicycle mounting table (1) along the guide rail (1), the movable carriages (3) may collide with each other, but the elastic member (6) causes an impact at the time of the collision. As a result of the absorption, generation of noise can be prevented, and damage to the device and the bicycle due to impact can be prevented.

FIG. 4 is a cross-sectional view showing the mounting structure of the elastic member (6).
The elastic member (6) includes a rubber sphere (hereinafter referred to as a sphere (6)) disposed in the internal space of the carriage body (31).
A rubber cover member (61) is attached to the end face of the movable carriage (3) (the end face of the carriage body (31)), and a hole (62) smaller than the diameter of the sphere is attached to the cover member (61). Is provided. And a part of spherical body (6) protrudes outside from this hole (62).

As shown in FIG. 4, the sphere (6) is disposed in the internal space of the carriage body (31).
As a result, the sphere (6) is prevented from falling off, the shock absorbing function can be exhibited over a long period of time, and noise generation and damage to the device and the like can be prevented.

5A and 5B are views showing the cover member 61, wherein FIG. 5A is a front view, FIG. 5B is a right side view, and FIG. 5C is a rear view.
The cover member (61) is made of a rubber member having a shape in which the vicinity of the end of the quadrangular pyramid is cut out in a circular shape as indicated by an imaginary line, and a circular hole formed by this cutting is formed by a part of the sphere (6). It is a hole (62) for protruding.
The peripheral edge portion of the hole (62) is in close contact with the sphere (6), whereby the sphere (6) can be stably held.

  The diameter of the sphere (6) is substantially equal to the height and width of the internal space of the cart body (31), which prevents the sphere (6) from moving freely up and down and left and right. 31) is stably positioned and held in the internal space.

As shown in FIG. 4, the rotating shaft (41) of the first roller (4) and the rotating shaft (51) of the second roller (5) protrude into the internal space of the carriage body (31). However, in the present invention, only one of the rotating shafts may be protruded.
The surface of the sphere (6) is in contact with one or both of the rotation shaft (41) and the rotation shaft (51) (the rotation shaft (41) in the illustrated example). Thereby, the sphere (6) moves to the side opposite to the end face of the moving carriage (3) (end face of the carriage body (31)), that is, to the inner side of the inner space of the carriage body (31) (right direction in FIG. 4). This prevents the sphere (6) from entering the internal space of the carriage body (31) due to the impact at the time of collision.
In addition, since the structure for fixing the sphere (6) using the rotating shafts (41) and (51) of the roller is employed as described above, a separate part for fixing the sphere (6) becomes unnecessary. The score can be reduced.
Further, since the sphere (6) is held in a rotatable state, even when the sphere (6) is worn or damaged with use, a new one can be obtained by rotating the sphere (6). It can be used with its surface exposed. Therefore, stable performance can be exhibited over a long period of time, and maintenance is easy.

FIG. 6 is a partial view showing a state in which the mobile carriages (3) collide with each other.
As shown in the figure, when the movable carts (3) collide with each other, the cart bodies (31) do not directly hit each other, but the elastic members (6) (spheres (6)) hit each other.
Here, since the elastic member is made of a spherical body, the elastic members come into contact with each other almost always at the same point, and a stable shock absorbing function can be exhibited.

FIGS. 7A and 7B are diagrams showing a modified example (first modified example) of the sphere (6), where FIG. 7A is a left side view, FIG. 7B is a front view, and FIG. 7C is a right side view. Moreover, (d) is a front view showing another modified example (second modified example). The left side view and the right side view of the second modified example are the same as those of the first modified example, and are not shown.
The sphere (6) of the first modification is a deformed sphere having a shape in which the flat portions of the small-diameter hemisphere (63) and the large-diameter hemisphere (64) are joined so that the centers of both the flat portions coincide. Consists of.
Here, one or both of the small-diameter hemisphere (63) and the large-diameter hemisphere (64) may be semi-elliptical spheres. The sphere (6) of the second modified example is a small-diameter hemisphere (63). The large-diameter semi-elliptical sphere (64) is formed of a deformed sphere having a shape in which the plane portions are joined so that the centers of both plane portions coincide. When the sphere (6) of the second modification is used, the radius (D1) in the direction perpendicular to the joint surface of the large-diameter semi-elliptical sphere (64) with the small-diameter hemisphere (63) is parallel. It is preferable to be larger than the radius (D2). This is because when the radius (D1) is increased, the large-diameter semi-elliptical sphere (64) comes into the back of the carriage body (31), so that the sphere (6) is stably held, It is because it becomes easy to contact | abut one or both of a rotating shaft (41) and a rotating shaft (51).

  About a deformed sphere, a small-diameter hemisphere or semi-elliptical sphere (63) and a large-diameter hemisphere or semi-elliptical sphere (64) may be formed after being formed separately, but the strength, productivity, It is preferable to integrally mold from the viewpoint.

FIG. 8 is a view showing a cover member (61) that can be used in combination with the sphere (6) of the first or second modification, wherein (a) is a left side view and (b) is a front view. , (C) is a right side view, and (d) is a cross-sectional view.
The cover member (61) includes a fitting portion (611) fitted to the end surface of the movable carriage (3) (end surface of the carriage main body (31)) and a covering portion (612) covering the end of the carriage main body (31). ).

The surface facing the inner surface of the bogie main body (31) of the fitting portion (611) is formed in a concavo-convex shape having convex portions (613) and concave portions (614) alternately (see FIG. 8B).
The convex part (613) is formed obliquely so as to gradually increase from the right side (opposite side of the covering part) to the left side (covering part side). As a result, when the fitting portion (611) is fitted to the end portion of the carriage body (31), the oblique portion exhibits a guide function and is easy to fit, while it is difficult to come off when an external force or impact is applied.
A circular hole (62) from which a part of a small-diameter hemisphere or semi-elliptical sphere (63) protrudes is formed in the covering part (612).

FIG. 9 is a cross-sectional view showing the mounting structure of the sphere (6), and shows a state in which the sphere (6) shown in FIG. 7 and the cover member (61) shown in FIG. 8 are used in combination.
At this time, an annular flange (65) formed around the joint surface of the small-diameter hemisphere or semi-elliptical sphere (63) and the large-diameter hemisphere or semi-elliptical sphere (64) is formed by the cover member (61). It contacts the inner surface of the covering portion (612). Therefore, the sphere (6) can be reliably fixed at a predetermined position by using a simple method such as applying an adhesive to the collar (65) without using another fixing means. Although not shown in the figure, as shown in FIG. 4, a large-diameter hemisphere or semi-elliptical sphere (64) is applied to one or both of the rotation axis (41) and the rotation axis (51). The position of the sphere may be fixed by contact.

  Further, when the small-diameter hemisphere or semi-elliptical sphere (63) protrudes from the hole (62), the radius of curvature of the protruding portion becomes small, and when the movable carriages collide with each other, the elastic member (6) (sphere ( 6)) It is possible to always make point contact with each other, and while exhibiting a high impact absorbing function, a large-diameter hemisphere or semi-elliptical sphere (64) comes to be located in the interior space of the cart body. Therefore, the sphere (6) is stably held.

  When the sphere (6) is damaged or worn, the sphere (6) can be easily removed by removing the cover member (61) from the carriage body (31), and maintenance can be easily performed.

FIG. 10 is a view showing the guide rail (1), in which (a) is a plan view, (b) is a front view, and (c) is an AA line enlarged sectional view.
The guide rail (1) is a long linear member serving as a track when the movable carriage (3) fixed to the lower part of the bicycle mounting base (2) moves, and is relative to the floor surface (installation surface). And a substantially parallel horizontal plane (11) and a vertical plane (12) substantially perpendicular to the floor surface.

The horizontal plane (11) is composed of a pair of surfaces arranged at intervals in parallel to each other, and the first roller (4) rolls between the pair of horizontal planes (11) (see FIG. 3).
The vertical surface (12) is also composed of a pair of surfaces arranged parallel to each other and spaced apart, and the second roller (4) rolls between the pair of vertical surfaces (12) (see FIG. 3). ).
In this way, the first roller (4) and the second roller (5) are respectively sandwiched between the horizontal plane (11) and the vertical plane (12) and rolled, so that both rollers are reliably brought into contact with the rail. Can be rolled. This makes it possible to stably move and move the movable carriage (3) and the bicycle placing table (2) fixed to the upper part thereof along the rail.

Here, the rolling surfaces (outer peripheral surfaces) of the first roller (4) and the second roller (5) are formed in a circular arc shape in cross section (see FIG. 3), so that the pair of horizontal surfaces (11) and the pair of rollers The first roller (4) and the second roller (5) sandwiched between the vertical surfaces (12) are allowed to be slightly inclined.
As a result, for example, even if there is a dimensional error in parts such as guide rails or an error during assembly, the roller is less affected by tilting during rolling, ensuring smooth running. It becomes possible.

As shown in FIG. 10C, the guide rail (1) has a substantially W-shaped cross section in which two U-shaped portions are arranged in a perpendicular direction. More specifically, two U-shaped portions (1a) and (1b) connected at a right angle, and an extending portion (1c) extending at a further right angle from the end of one U-shaped portion (1b). And integrated.
Since the guide rail (1) has such a cross-sectional shape, the first roller (4) and the second roller (5) can be inspected and repaired simultaneously from one side (inside) of the guide rail. It becomes. Further, since the guide rail (1) is formed from a single member and the two U-shaped portions are opened in the same direction (inward), the workability of installation and maintenance is very excellent. For example, it is easy to remove foreign matters such as dust and sand that have entered the guide rail.

Between the pair of guide rails (1), a plurality of rail fixing bars (7) are disposed and fixed at right angles to the guide rail (1) at intervals (see FIG. 1).
FIG. 11 is a view showing the rail fixing bar (7), where (a) is a plan view and (b) is a side view.
The rail fixing bar (7) is made of a U-shaped member (channel material) whose opening is disposed downward, and screw holes (71) and through holes (72) by burring are formed in the vicinity of both ends. Is formed. An anchor bolt is inserted into the through hole (72), and thereby the rail fixing bar (7) is fixed to the floor surface (the ground or the like).

  A through hole (1d) is formed in the extending portion (1c) of the guide rail (1) (see FIG. 10). As shown in FIG. 3, the extending portion (1c) is connected to the rail fixing bar (7). The guide rail (1) is fixed to the rail fixing bar (7) by placing it on the upper surface and matching the through hole (1d) with the screw hole (71) and screwing the bolt (8).

Thus, in the state which fixed the extension part (1c) to the rail fixing bar (7), the bottom face of one U-shaped part (1a) becomes substantially the same height as a floor surface (ground).
At this time, the positions of the pair of horizontal surfaces (11) provided to the pair of vertical surfaces (12) provided in the U-shaped portion (1a) and the other U-shaped portion (1b) connected to the U-shaped portion (1a) are also provided. Since it becomes low, the position of a 1st roller (4) and a 2nd roller (5) will also become low.
As a result, the height of the bicycle mounting table (2) fixed on the movable carriage (3) from the floor surface becomes very low, and even a powerless person can easily put the bicycle on the bicycle mounting table (2). It becomes possible to put on.

  Moreover, as shown in FIG. 10, a plurality of drainage through holes (13) are formed at predetermined intervals on the bottom surface of one U-shaped portion (1a) of the guide rail (1). It is possible to prevent rainwater and the like from being stored in the guide rail and causing rust.

  The bicycle storage device according to the present invention can be suitably used in a place where quietness in use is required in addition to storing a large number of bicycles in a small space such as an apartment house.
