Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a device for parking bicycles in as little floor space as possible.

(Prior art) Attempts have already been made to support bicycles in an upright position to reduce the floor space occupied by each bicycle and increase the number of bicycles parked per unit area. There is one disclosed in Publication No. 62-1978.

(Problems to be solved by the invention) What was disclosed in the above-mentioned Japanese Patent Application Laid-open No. 1983-1978,
Furthermore, all of the bicycle parking devices that have already been proposed lift the bicycle into its standing position by inputting input from its front wheel.
Not suitable for old people. In addition, the fixing means for maintaining this posture when the bicycle is upright is
Both systems have come to rely on human operations, so it is necessary to perform a lifting operation to stand up as well as a fixing operation. Therefore, it is necessary to hold the bicycle with one hand and fix it with the other hand. Problems remain, such as the lack of safety and the great danger of both parking and taking out bicycles.

This invention was made to solve these problems, and allows for easy operation, i.e., parking and retrieval of bicycles with extremely little force, and locking and unlocking can be done automatically by mechanical operation. The purpose is to obtain equipment.

(Means for Solving the Problems) The bicycle parking device according to this invention is suspended by an upright guide column and a wire that is guided in a vertically movable manner by the guide column and is connected to a balancer provided at the upper end of the column. The front wheel holding mechanism includes a frame body for guiding the front wheel, a lever provided at the inner end thereof and rotating by the pressing action of the front wheel, It consists of a clamping mechanism consisting of a slide body that is pushed down by this lever and a gripping lever that operates to clamp the front wheel when the slide body descends.Furthermore, the front wheel holding mechanism is mounted on the floorboard, and when the slide body is lowered to the lower limit, the gripping mechanism is configured to hold the front wheel. The main feature is that an unlock bar is pushed up to unlock the front wheel from being held by the grip lever, and a locking hook is provided that engages with the open tip of the grip lever to securely hold the front wheel holding mechanism. be.

(Function) In this device, when the front wheel is fed in when the bicycle is parked, the lever rotates and pushes down the slide body, which causes the gripping lever to move away from the locking hook and clamp the front wheel. At the same time, the lifting force stored in the balancer acts on the bicycle, allowing it to be lifted up with just a light amount of human effort in the locked state. When the bicycle is taken out, if the bicycle is moved slightly backwards and downwards, the front wheel descends together with the front wheel holding mechanism, and finally the gripping lever is released by pushing up the slide body by the unlocking bar, and at the same time, the front wheel holding mechanism jumps up by the locking hook. is prevented and the bicycle is completely released.

(Example) This invention will be described below based on an example shown in the drawings. That is, numeral 1 denotes a guide column erected and fixed on a floor plate 2, which has a lipped channel-shaped cross section and has a balancer 3 attached to its top. This balancer 3 has a torsion spring 4 that can offset the front wheel holding mechanism and the weight of the bicycle, which will be described later.
A drum 5 is integrally provided at the end of the shaft to which the spring 4 is connected. Reference numeral 6 denotes a cart housed within the guide column 1, and this is provided with a pulley 7 that rolls along the inner surface of the column 1 as shown in FIG. and is connected to a wire 9 wound around the drum 5. In other words, the cart 6 is suspended by the wire 9 and is easily moved up and down using the guide column 1 as a guide.

Reference numeral 10 denotes a front wheel holder, which is integrally fixed to the outer surface of the trolley 6, and has a frame body consisting of a guide plate 11 that guides and supports the front wheel of the bicycle A, and side plates 12 that stand on both sides of the guide plate 11 and stand opposite to each other. 13 and the frame 13
A lever rod 16 rotatably supported by a shaft 14 at the inner end thereof and provided with a roller 15 at one end, a slide body 18 and a slide body 18 which are pushed down by the working end 17 of the lever rod 16 as the lever rod 16 rotates.
and a gripping mechanism 2 consisting of a pair of left and right gripping levers 19 that are opened and closed by vertical sliding motion.
Consists of 0.

By the way, the holding mechanism 20 is housed in a box body 21 that is fitted and fixed to the rear end of the frame body 13, and the slide body 18 is connected to a bolt 22 screwed through the back side of the box body 21 and the box body 21. A long hole 24 provided in the lid 23
The gripping lever 19 has a bent shape as shown in FIG. It is mounted so as to be openable and closable, and each of the oblique legs is held between actuating bodies 27 and 28, which are made of bearings and the like provided on the box body 21. Therefore, the gripping lever 19 that moves the slider 18 downward is pushed inward by the one of the actuating members 27, and is closed as shown by the imaginary line in FIG. 29 matches, resulting in a so-called locked state. Further, when the slide body 18 is pushed up, it is pushed by the other effecting body 28 and opens as shown by the solid line in FIG.
are separated by a large distance, resulting in a so-called unlocked state. Note that the lever 16 serves as an eye for pushing down the slide body 18, and its shape is not specified.

Reference numeral 30 denotes an unlocking bar installed vertically on the floor plate 2, which faces the slide body 18 and pushes up the slide body 18 when the front wheel holding mechanism 10 has descended to the lower limit.
This serves as an eye for unlocking the grip lever 19. Reference numeral 31 designates locking hooks installed on the floor plate 2 on both sides of the gripping lever 19;
This engages when the lock 9 is in the unlocked position and serves as a safety device to prevent the front wheel holding mechanism 10 from jumping up. In this invention, when the front wheel holding mechanism 10 is at the lower limit, the torsion spring 4 of the balancer 3 is stored, and an upward tensile force is always applied via the wire, thus functioning as a so-called balancer. is working. Note that 32 in the figure is a guide frame provided on the floorboard 2.

This invention has a structure as described above in the embodiment. To park the bicycle, insert the front wheel of bicycle A into the frame 13 along the guide plate 11, and push the lever 16 with the front of the tire. This rotates, pushes down the slide body 18 with the active end 17, closes the grip lever 19 that operates integrally with this, and locks the front wheel by gripping the front wheel between the gripping piece 29 and the plate piece 29a. In this state, if you hold the handlebars of bicycle A and lift it slightly, the stored force of balancer 3 is acting on bicycle A, so that bicycle A stands up as shown in the imaginary line shown in Fig. 1 and remains safely locked. The wheel is stably supported on the guide frame 32.

To take out bicycle A, pull it backwards and downwards, hold the handlebars, and it will descend gently.
When the front wheel holding mechanism 10 reaches the lower limit position, the slide body 18 is pushed up by the unlocking lever 30, and the action body 2 is moved upwardly by the gripping lever 19.
8 acts to open the clamping piece 29, the upper end of the gripping lever 19 engages with the locking hook 31, and the front wheel holding mechanism 10 is completely fixed and held in the unlocked position, allowing the bicycle to be taken out without any trouble. I can do it.

By the way, in place of the balancer 3 using the energy storage spring in the above-mentioned implementation of this invention, the same effect can be achieved even if a means such as providing a turning pulley at the upper end of the guide column 1 and suspending a heavy lock from the end of the wire 9 is adopted. You can expect good results. In addition, consideration has been given to the gripping piece 29 and the plate piece 29a at the end of the gripping lever 19 so that they can securely grip the front wheel and do not damage the spokes.

(Effects of the invention) As described above, this invention automatically clamps and holds the front wheel by simply pressing the lever with the front wheel of the bicycle, and at this point the front wheel holding mechanism locks the locking hook. Since the lifting force from the balancer is further applied, the bicycle can be easily lifted and stood up by applying a very small external force. Furthermore, when taking out the bag, it can be easily operated and unlocked automatically. Therefore, there is no danger at all and even children can easily use it. Normally, the front wheel holding mechanism is automatically locked and the vehicle is completely prevented from jumping, so it is perfect. In addition, this invention allows multiple bicycles to be parked side by side, facing each other, or even in a circle, which greatly reduces the floor space occupied by bicycles, making it possible to park a large number of bicycles in limited areas, such as in front of stations. It is suitable and effective as wheel equipment, and has great effects in terms of environmental conservation and theft prevention.
