Description

[Detailed Description of the Invention] The present invention relates to a suspension system for a two-wheeled vehicle or the like.

Recently, various bicycle parking devices for two-wheeled vehicles such as bicycles have been proposed.

Generally, important conditions for bicycle parking devices include excellent storage capacity and operability when loading and unloading.

The present invention was developed based on the above-mentioned points, and an object of the present invention is to provide a suspension system for a two-wheeled vehicle, etc., which has a simple structure and excellent operability.

Next, an embodiment of the present invention will be described with reference to the drawings.

The suspension system of the present invention is a device for holding a front wheel of a two-wheeled vehicle A and suspending it in the air, instead of parking the two-wheeled vehicle A such as a bicycle flat on the ground as shown in FIG.

[B] Hook device In Fig. 1, 1 is a frame for suspending a plurality of two-wheeled vehicles A, and horizontal suspension beams 12 are installed in multiple stages between the vertical supports 11 of this frame 1. .

Two arms 2 are provided protruding from the vertical surface of each beam 12 so as to face each other.

The inner facing distance between the arms 2 is at least equal to the width of the wheel to be held.

Then, hooks 3 are attached between the arms 2 so as to butt each other.

The hook 3 is made of a plate having sufficient strength to support the weight of the two-wheeled vehicle A.

The base end of each hook 3 is pivotally supported on each arm 2 using a pin 4 or the like so as to allow rotation only in the horizontal direction.

Further, the total length of each hook 3 is set so that the distance between the tips of a pair of hooks 3 is smaller than the width of the wheel B when both hooks 3 are aligned on the same straight line.

This is the distance between the ends of the pair of hooks 3 on wheel B.
This is because if the width is set larger than the width of the hook 3, the wheel B will freely slip out from between the pair of hooks 3, making it impossible to hold the wheel B.

Further, as shown in FIGS. 3 and 4, a spring 5 is attached between the base end of each hook 3 and each arm 2, so that even if a pair of hooks 3 rotate, they always return to the same straight line.

In addition, as shown in FIGS. 3 and 4, the pair of hooks 3 can be inserted into each arm 2 formed by providing a notch in the side surface of a hollow steel material to be pivotally supported.
It may be pivoted on either the upper or lower surface.

Therefore, in addition to disposing one end of the hook 3 built into the arm 2 made of a hollow steel material, it is also possible to rotatably support the hook 3 on the upper surface of the arm 2 with a pin.

Next, the operating state of the suspension system will be explained.

[B] When holding the wheel: Grip and lift the wheel B of the two-wheeled vehicle A using an arm robot or the like, and bring the lifted wheel B close to between the arms 2 protruding from the suspension beam 12.

At this time, both hooks 3 connecting the arms 2 are positioned in a straight line by the force of the spring 5.

Furthermore, when the wheel B is pressed against the pair of hooks 3, the pair of hooks 3 horizontally rotate toward the base end side of the arm 2, and the distance between the tips of the hooks 3 gradually widens accordingly.

When the wheel B passes between the pair of hooks 3, the pair of hooks 3 are restored to the same straight line by the restoring force of the spring 5 at the next moment.

As a result, the pair of hooks 3 become like a single rod and are inserted between the spokes of the wheel B.

Once the wheel B is hooked to the pair of hooks 3, the arm robot etc. move away from the wheel B and retreat to a predetermined standby position.

A two-wheeled vehicle A is suspended in the air with its wheels B held by a pair of hooks 3.

[B] Force acting on the hook If we consider the force acting on the suspension system when motorcycle A is suspended, we will find the following.

That is, the weight of the two-wheeled vehicle A acts in a direction that pushes down the free ends of the pair of hooks 3.

Each hook 3 is pivotally supported by each arm 2 in a state where vertical deformation is prevented.

In addition, the weight of the motorcycle A acting on each hook 3 acts to rotate each hook 3 in the horizontal direction, but the spring force of the spring 5 connected to the tail end of each hook 3 counteracts this. maintain the linearity of hook 3.

Therefore, wheel B of motorcycle A is attached to a pair of hooks 3.
There is no worry that the motorcycle A will come off between the pair of hooks 3 after being inserted between them.

Therefore, the two-wheeled vehicle is securely gripped by the hook 3,
There is no easy way to break away from these three hooks.

[C] When the wheel is detached The arm robot used to suspend the motorcycle A grasps the wheel B held by the suspension system again and moves it horizontally, that is, from the hook 3.
move back in the direction of rotation.

As a result, the wheel B pushes the hook 3 toward the distal end of the arm 2, widens the distance between the distal ends of the hook 3, and allows the wheel B to be removed from the suspension system.

Since the present invention is as explained above, the following effects can be expected.

<A> Two hooks are placed on a horizontally arranged beam, allowing only horizontal loading and unloading, and a load-bearing structure in the vertical direction.

Therefore, the structure of the device is simple and the operation of gripping and releasing the wheels of the two-wheeled vehicle is accurate.

<B> Rather than simply hanging the wheels from a rod and suspending them, a pair of opposing hooks maintains a straight line, so even if the wheels move vertically or horizontally, they can be easily removed from the hooks. Never.

Therefore, the two-wheeled vehicle can be suspended in a highly safe state.

<C> The wheel can be easily gripped and removed by simply moving the wheel in and out between the hooks with a constant force.

Therefore, in addition to the operation of putting in and taking out the wheels, it is not necessary to separately operate the holder, so the operability is excellent.

<D> Of course, it is possible to grip not only the front wheel of a two-wheeled vehicle but also the rear wheel, and a similar effect can be expected in the case of a three-wheeled vehicle as well.

Claims (1)

[Scope of claim for utility model registration] A device for suspending a motorcycle, etc. by holding the wheels of a motorcycle, etc., in which the base ends of a pair of arms arranged parallel to each other in the horizontal direction are fixed to a vertical surface. A pair of hooks facing horizontally are placed between the arms, and the length of each hook is set so that when both hooks are placed in a straight line, the distance between the tips of both hooks is within the width of the wheel. The base end of each hook is pivoted with a pin to allow each arm to rotate only in the horizontal direction, and the tail end of each hook is supported so that both hooks are positioned in a straight line against the weight of the motorcycle. A suspension system for motorcycles, etc. that is constructed by attaching a biasing spring member.
