Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application: The present invention relates to a unit type bicycle parking device that stores bicycles three-dimensionally and makes more effective use of a narrow installation space.

Conventional technology: Recently, with the rapid spread of bicycles, bicycles are being parked in front of public transportation stations, supermarkets, and other places where many people are concentrated. For this reason, local governments and public corporations are struggling with how to organize these bicycles.

In light of this current situation, various devices for organizing and parking bicycles have already been devised, and most of them are in practical use. For example, as a method for parking,
A so-called parking stand as disclosed in Publication No. 3 is known. Furthermore, Japanese Utility Model Publication No. 57-571.63 discloses a type of table in which a bicycle can be placed on a table that rotates on a flat surface for convenient loading and unloading of the bicycle. In addition to this, there are also devices that allow bicycles to be hung in an almost upright position to make effective use of narrow spaces.

Problem to be solved: With the various types of parking devices mentioned above, the user can place the wheels directly on the support part of the parking device at or near the ground, and park in as narrow a space as possible. The purpose is to make it possible to park a large number of bicycles in an organized manner. In particular, when bicycles are lined up in parallel and parked at different heights, as in the first example, the number of bicycles that can be accommodated per unit area can be increased by reducing the spacing between them, but it is difficult to put bicycles in and out of the parking facility. This makes it difficult and problematic to use. Moreover, with this type of system, the space required to enter and exit the bicycle correctly is 1.2 to 1.2 mm per bicycle. ．． 4.7
It requires a storage area of 7Z'.

In addition, the second example, in which parking is done on a rotating body, has a somewhat larger capacity than the first example, but even in this case, it is not possible to install equipment close together, and parking is expensive. The capacity is not very effective.

Although it may be possible to increase the storage capacity by parking the bicycle in an upright position, it is not very effective and is often inconvenient in terms of handling, as it requires the bicycle to be parked upright.

Means for Solving the Problems: The present invention solves the above-mentioned conventional problems, reduces the installation area, increases the capacity, and can be adapted to the situation of the installation site without complicating the structure. To provide a bicycle parking device with a unit type three-dimensional circulation structure that can be easily expanded as needed.

That is, the present invention comprises an endless drive chain that is wound between a pair of sprockets arranged at a predetermined interval in the vertical direction, and a large number of bicycle mounting suspension frames whose tops are supported by pins on both sides of the drive chain at a predetermined pitch. and a frame that supports them; The bicycle mounting frame has an annular structure with a fixed part that can receive both wheels of the mounted bicycle and hold it upright, and the base is connected to the drive chain at the center of the top of the frame. The suspension frame is fixed and connected with a pin to the end of the support arm that protrudes to the side, and is suspended on both sides of the drive chain at an appropriate interval so that the center of gravity of the suspension frame is located on the suspension perpendicular line; is a device in which a required hanging frame is driven by a drive machine equipped with a control mechanism that can selectively move to and stop the bicycle receiving/receiving (loading/unloading) position.

In the present invention, the bicycle mounting suspension frame includes a main body in which two rings are arranged in parallel at least at a distance slightly wider than the width of the wheel part and are interconnected and integrated, and a lower half of the main body is used to support the bicycle on which the bicycle is mounted. It consists of a wheel fixing part into which a part of the wheel can be fitted and locked, and a hanging pin attachment part fixed to the top of the main body on a perpendicular line passing through the center of gravity of the main body.

This hanging frame is rotatably attached to the ends of support arms that protrude horizontally from both sides at equal intervals and perpendicular to the drive chain, either directly or by connecting with a hanging end that is fixed downward. It is suspended.

In the present invention, with respect to a drive chain that circulates and moves a large number of bicycle suspension frames, the support arms of the suspension frames have their main parts supported by links with attachments provided at a required pitch on the chain, preferably with reference to the chain. and are provided so as to support the hanging frame symmetrically on both sides. The sprocket that wraps around and supports the drive chain is axially supported by a pair of bearings attached to the frame so that the upper sprocket does not come into contact with the bicycle mounted on the suspension frame as it moves. The objects are supported by bearings installed on the frame so that they can be driven by a drive shaft. In this drive section, an electromagnetic clutch/brake is interposed in the rotational force input section from the drive machine, and this electromagnetic clutch/brake can be called to the position where the suspension frame at the desired address receives and receives the suspension frame mounted on the bicycle. It has a configuration in which it is connected to an electric control mechanism that can be selectively operated. Alternatively, a unique operation piece is attached to each hanging frame support, and a large number of limit switches are arranged so that the control unit can stop the hanging frame when it reaches the required hanging frame at the receiving and discharging position. A method of controlling by using the call control mechanism can also be adopted as the call control mechanism.

In addition to the above-mentioned type, the bicycle mounting suspension frame according to the present invention has two omitted circular rings with a straight lower part arranged in parallel at a distance that allows the wheels, drive chain cover, etc. to fit into the frame. It is also possible to adopt a structure in which the rings are interconnected to form an integrated structure, and when the mounted bicycle is received in the suspension frame, the tangent lines of both front and rear wheels touch the straight support end of the suspension frame and serve as a support point. .

In addition, the bicycle mounting hanging frame may optionally have a triangular shape, trapezoidal shape, etc. when viewed from the front, within a size range that has a space that can accommodate a bicycle.

The present invention also provides a drive chain including a plurality of sets of bicycle mounting suspension frames, a support arm for driving the suspension frames in a cyclically movable manner, a pair of sprocket wheels for winding and driving the drive chain, and a support mechanism for the drive chain. , a drive mechanism for selecting a hanging frame and moving it to a predetermined position, and a support frame are configured as one unit, and by arranging the required number of units in parallel and connecting them to the drive shaft side, one unit can be constructed. Can be driven by a prime mover. Of course, a clutch should be inserted in the drive section of each unit so that power is transmitted only to the drive chain of the necessary unit, and the control section should be set so that the required hanging frame is selected and activated/stopped. Bye.

In addition, when adopting the above-mentioned oval-shaped bicycle mounting suspension frame, at the position where bicycles are received and received (taken in and taken out), a lifting device is placed directly below it that raises and lowers so that the highest position almost matches the level of the bicycle loading floor. If this is provided, it will be easier to receive and receive bicycles from the hanging frame.

Function: The bicycle parking device of the present invention is a frame installed inside a building that supports upper and lower sprocket wheels so that a required number of suspension frames can be circulated in the vertical direction. If this is the receiving and receiving position for the frame, by stopping the suspension frame at this position and bringing the bicycle into the ring-shaped suspension frame, the bicycle can be placed between the two rings in the main body of the suspension frame. The wheels fit in and are supported by the fixed part, and are correctly supported without tilting. In this state, parts that are wider than the wheels, such as the handle, pedals, and saddle, are located in the empty space of the hanging frame, so there is no problem. When mounting the bicycle, balance is maintained by holding the drive chain and placing it on the suspension frames on both sides.

The loaded hanging frames are moved up and down in a fixed direction one by one, and bicycles can be loaded and accommodated on all hanging frames that are chained together by a drive chain.

Each hanging frame is pin-connected and supported at the top by a support arm on a perpendicular line passing through its center of gravity, so that it is automatically balanced and suspended in a stable posture. Furthermore, the center of gravity of the suspension frame moves in a position parallel to the travel line of the drive chain that is rising or falling, so that no irregular external force is applied to the drive chain.

In addition, a predetermined number is assigned to each suspension frame in advance, and when the owner of a bicycle that has been loaded and stored first wants to retrieve that bicycle, the operator controls the suspension frame with the preset number. By calling the bicycle, the drive mechanism is actuated to move the target hanging frame to the receiving and discharging position, and the bicycle is taken out from the hanging frame.

In this way, hanging frames are arranged on both sides of a series of drive chains, and the number of bicycles can be accommodated three-dimensionally, so due to the installation space, multiple units of this type are arranged in parallel, and the drive shaft is If they are connected, they can be driven by a single prime mover. Of course it's good.
