Description

The present invention relates to a wheel chocking device for automobiles in a parking space.

Generally, a car stop installed in a parking lot has concrete blocks installed according to the distance between the left and right wheels.

However, if multiple protrusions such as concrete blocks are installed in the parking space, there is a risk that people getting on and off the car and ordinary pedestrians may stumble, which is dangerous for pedestrians. ..

For such dangers, it acts as a bollard only when the car is parked, and for pedestrians if the parking space can be kept flat to match the ground and the approximate surface position when not parked. It's safe.

Conventionally , as a parking space when an empty vehicle is parked, a structure for standing up a rear wheel retreat prevention plate on which a bollard function works when the vehicle is parked has been disclosed (Patent Document 1).

In FIG. 5A of Patent Document 1, a high-height stop bollard 41 is formed by bending a plate material, a tread plate 44 is formed in front of the high-height stop bollard 41, and a reverse run with a low front plate height of the tread plate 44. It is a vehicle mounting pallet provided with a bollard device on which a bollard 42 for prevention is formed.

Further, in FIG. 6A of Patent Document 1, the portion of the tread plate 44 has a laminated structure, and the position of the laminated portion can be adjusted in the front-rear direction. It is divided into a rear bollard 46 forming a bollard 41 and a front bollard 47 forming a front bollard 42 for preventing reverse running. This is a vehicle-mounted pallet provided with a bollard hole 48, and a bollard device capable of adjusting the distance Q between the bollard 41 and the reverse run bollard 42 by the bollard 49.

Next, in Patent Document 2, a triangular bollard 2 is provided on one side of the base plate main body 1, and a small protrusion 3 for preventing reverse movement is provided on the opposite side at intervals at which the tire X of the wheel can be placed. At the same time, it is a parking safety device in which a spike-shaped needle group 4 for contacting the ground is projected over the entire bottom surface of the base plate main body 1.

In the above Patent Document 1, the height of the front reverse run prevention bollard 42 is lower than that of the rear stop bollard 41, and the front reverse run prevention bollard 42 is overcome in order to be inserted into the tread plate 44. There is a problem that it must be done, and since the front and rear parts 41 and 42 are always protruding, there is a risk of stumbling when passing like a concrete block.

In the above Patent Document 2, since the height of the small protrusion 3 for preventing reverse movement in the front portion is lower than that in the triangular bollard portion 2 in the rear portion, there is a problem in the reverse movement prevention effect, and when the wheel enters and exits. The problem is that you have to overcome each time, and because the front part is always protruding, there is a risk of stumbling when passing like a concrete block.

The present invention is completely different from the structure of the above-mentioned conventional bollard device, and is capable of forming a triangular chevron state from a flat state or forming a flat state from a chevron state by the driving friction of wheels.

The first of the present invention is to connect a tire receiving portion and a support plate to both ends of a rectangular in-vehicle plate in the front-rear direction in a wheel chocking device of an automobile, and one ends thereof are connected to each other by a first hinge portion and a second hinge portion in this order. Then, the other ends of the tire receiving portion are connected to both ends of the square bottom substrate arranged on the lower surface of the in-vehicle plate in the front-rear direction by a third hinge portion, and the tire receiving portion and the support plate are flattened by moving the in-vehicle plate back and forth. The shape of the tire can be changed to the shape of the chevron stopper, or the shape of the chevron can be changed to the flat shape.

The second aspect of the present invention is a tubular roller that is loosely fitted to the shaft of the hinge in a part of the first hinge as a means of moving the square vehicle-mounted plate back and forth in the wheel chock device of the automobile according to the first invention. In addition to the provision of a regulation stopper, the bottom substrate is provided with a regulation stopper for receiving a regulation piece for the front-back movement of the vehicle-mounted plate.

The third aspect of the present invention is to use a rod-shaped roller or a ball roller as a means for moving the square vehicle-mounted plate back and forth between the vehicle-mounted plate and the bottom fixing plate in the wheel chocking device of the automobile according to the first invention, and use the bottom substrate as a roller. A regulation stopper is provided to receive the regulation piece for the front-back movement of the in-vehicle board.

The fourth aspect of the present invention is to connect a tire receiving portion and a support plate to one end of a rectangular in-vehicle plate in the front-rear direction in a wheel chocking device for automobiles, and to connect one ends to each other by a first hinge portion and a second hinge portion in this order. Then, the other end of the tire receiving portion is connected to one end in the front-rear direction of the square bottom substrate arranged on the lower surface of the in-vehicle plate by a third hinge portion, and the tire receiving portion and the support plate are moved back and forth by the square in-vehicle plate. Is made to be able to shift from the flat shape to the shape of the chevron stopper, or from the shape of the chevron stopper to the flat shape.

Since the present invention has the above configuration, it has the following effects.
First, in the parking space, it can be installed and fixed on the ground without excavating the ground or providing special equipment.

Secondly, the tire receiving portion and the support plate on the side where the drive wheels are stopped are formed from a flat shape to a triangular chevron shape by friction drive only when the drive wheels enter and run on a flat in-vehicle plate. be able to.
Further, when the driven wheel that has entered exits the vehicle-mounted plate, the chevron shape including the tire receiving portion and the support plate falls backward and can be folded into a flat shape.

Thirdly, the tire receiving portion and the support plate on the side where the drive wheels are stopped are formed into a chevron shape, and at the same time, the tire receiving portion and the support plate on the front side can be formed from a flat shape to a triangular chevron shape. Even when it is installed on a slightly inclined surface, it can exert the function of a bollard even in a situation where it slips forward.

Fourth, since it is folded into a flat shape when the vehicle is empty, it does not protrude when the vehicle is empty unlike a conventional concrete block, so that there is no risk of tripping when walking.

According to claims 1 to 3 of the present invention, it is possible to perform approaching and exiting not only from one direction (for example, to the left in FIG. 1 ) but also from another direction (for example, to the right in FIG. 1 ). ..
