Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a rubber tire stopper device, and more particularly, to a tire stopper for fixing a stopped vehicle by applying a protrusion in the vicinity of a tire ground portion of the vehicle.

[0002]

[Prior art]

 When a vehicle such as a passenger car or truck is parked in a parking lot or parked on a sloping ground, a tire stopper is often used to prevent the vehicle from being repositioned or moving for some reason. . This is the one that has a protrusion that can be fitted between the tire and the ground or directly contact the tire at the ground contact portion of the tire, or the protrusion itself.

As a portable type of the tire stopper, there is a steel stopper having a width of about 15 cm and bent in a triangular shape when viewed from the side. Such a tire stopper has the advantage that the tire can immediately hit the tire wherever the vehicle is parked. This is intended to exert a wedge effect between the tire and the ground, but due to the triangular shape, the friction area between the tire stopper and the ground is small, and the tire stopper itself may be displaced.

On the other hand, when the tire stopper is fixed to the ground or floor of the parking lot, it does not move even if a little force is applied. The protrusions used as such tire stoppers are often concrete blocks. This kind of car stop block is usually a precast product, but when constructing a parking lot, the block is placed in place and the anchors are passed in the vertical direction, and it is fixed by driving it into concrete or asphalt surface. It

Since the block for the car stop fixed in this way is selected to have a height of about 20 cm above the ground, unlike the above-mentioned triangular tire stopper, the contact position with the tire is set slightly higher. be able to. Furthermore, since it is fixed with anchors, it is unlikely that the block will shift.

[0006]

[Problems to be solved by the device]

 However, there are many opportunities to receive the force from the tires on the car stop block in the parking lot where cars come and go. At that time, a force is applied to the car stop block in the direction in which the block falls, so that a bending force acts on the anchor supporting it. Therefore, the anchor bends at the boundary between the ground such as concrete and the block, and pulling load is applied to the anchor. If this process is repeated, the car blocking block will float above the ground, and its low durability poses a problem.

Of course, since the corners of the concrete block may start to fall off, it is desired to develop a fixed type tire stopper with extremely little damage or breakage. The present invention has been made in view of the above problems, and an object of the present invention is to easily mount it on the ground or floor of a parking lot, and to use a vehicle weight to provide a tire stopper including a protrusion. It is an object of the present invention to provide a stopper device for a rubber tire which can improve stability.

Furthermore, it is an object of the present invention to realize a tire stopper that can be reliably fixed even in an unpaved dirt road or a parking lot in an empty space, and that can be easily prevented from sliding.

[0009]

[Means for Solving the Problems]

 INDUSTRIAL APPLICABILITY The present invention is applied to a tire stopper capable of fixing a stopped vehicle or preventing the vehicle body from slipping on a sloping land by applying a protrusion in the vicinity of the ground contact portion of the tire of a vehicle such as a passenger car. It The feature is that, with reference to FIG. 1, a base plate 2 having a tire mounting portion 2A having a width that allows at least one tire to be completely mounted on the vehicle by moving the vehicle forward and backward, and The base plate 2 is integrally provided at an end portion thereof and is provided with a protrusion 2B formed so as to come into contact with the tire in the vicinity of a ground contact portion of the tire.

A plurality of anchor holes 3 are formed in the base plate 2 in order to fix the base plate 2 to the ground or floor of the parking lot.

The protrusion 2 B is manufactured independently of the base plate 2, and the protrusion 2 B is preferably fixed to the base plate 2 by welding.

The protrusion 2B may be hollow.

The protrusion 2B may be formed by bending or the like so that a portion near the end of the base plate 2 is bulged upward as shown in FIG. 7, for example.

The protrusion 2B has a substantially trapezoidal shape when the tire is viewed from the side (see, for example, FIG. 1).

The protrusion 2B may have a partial arc shape when the tire is viewed from the side (see, for example, FIG. 2).

The protrusion 2B is integrated with the base plate 2 except for the narrow tire non-loading portion 2C on the side opposite to the tire loading portion 2A on which the tire can ride (see FIG. 1 and the like).

An anchor hole 3 is also provided in the non-tired portion 2C of the tire (see FIG. 1 and the like).

As shown in FIG. 9, a plurality of substantially needle-shaped spikes 9 can be implanted on the back surface of the base plate 2.

As shown in FIG. 10, a locking claw 10 in which an end edge of the base plate 2 is bent toward the ground may be provided on any of the edges of the base plate 2.

[0020]

[Effect of the invention]

 According to the present invention, since at least one tire can be completely mounted on the base plate, the base plate is pressed against the ground or floor by a part of the weight of the vehicle, and the base plate is displaced from its installation location. Force becomes difficult to act. Therefore, even if the vehicle moves forward and backward and the tire comes into contact with the protrusion, the tire stopper does not shift or float up, and the vehicle can be stopped at a predetermined position. Therefore, durability as a stopper device for rubber tires is improved as much as possible.

According to the second aspect of the present invention, the anchors can be struck in the plurality of anchor holes to fix the base plate to the ground or floor of the parking lot, thereby increasing the stopping effect of the vehicle. You can

According to the third aspect of the present invention, if the protrusion is manufactured independently of the base plate and is welded to the base plate, base plates of different sizes and sizes can be used to suit the usage environment. It can be attached afterwards, and it becomes easy to give flexibility to the preparation for the production of the tire stopper.

According to the invention of claim 4, since the protrusion is hollow, the weight of the tire stopper can be reduced and the material can be saved.

If the projection is formed by bending the portion near the end of the base plate as in the fifth aspect, the number of parts can be reduced, which is suitable for mass production. Of course, weight reduction is also realized.

According to the sixth aspect of the present invention, the tire can be securely stopped by making the protrusions have a substantially trapezoidal shape when the tire is viewed from the side.

If the tire is shaped like a partial arc when viewed from the side as in the invention of claim 7, the projection can be easily molded.

If a narrow tire non-mounting portion is left on the side opposite to the protrusion of the tire mounting portion, the stability of the base plate is improved and the rigidity can be increased. it can.

According to the ninth aspect, the base plate can be firmly installed by driving the anchor into the anchor hole provided in the tire non-mounting portion.

By arranging a plurality of substantially needle-shaped spikes on the back surface of the base plate as in claim 10, installation on the soil surface is easy and movement is easy.

According to the eleventh aspect, even if any one of the edges of the base plate is provided with a locking claw whose edge is bent toward the ground, it can be gripped on the topsoil and the installation state of the tire stopper is stable. .

[0031]

[Embodiment of the invention]

 Hereinafter, a stopper device for a rubber tire according to the present invention will be described in detail with reference to the drawings showing an embodiment thereof. FIG. 1 shows a tire stopper 1 which is provided with a protrusion 2B in the vicinity of the ground contact portion of a tire of a vehicle such as a passenger car so as to fix a stopped vehicle or prevent the vehicle body from slipping on a sloping ground. Is. The tire stopper 1 may be made of non-ferrous metal such as plastic, rubber, FRP, and aluminum die cast, but in this example, an iron plate or a steel plate is used.

The tire stopper 1 as described above includes a base plate 2 having a tire mounting portion 2 A having a width such that at least one tire can completely ride up when the vehicle moves forward or backward, and the base plate 2 thereof. And a protrusion 2B formed integrally with the end portion of the tire so as to come into contact with the tire near the ground contact portion of the tire. The protrusion 2B is manufactured independently of the base plate 2, and the protrusion 2B is fixed to the base plate 2 by welding or adhesion.

The base plate 2 has a rectangular planar shape, and a plurality of anchor holes 3 are formed in the base plate 2 in order to fix the base plate 2 to the concrete or asphalt-paved ground or floor of a parking lot. To be done. This iron plate has a thickness of, for example, 1 mm to 10 mm, and the protrusion 2B is integrated with the base plate 2 while leaving a narrow tire non-loading portion 2C on the opposite side of the tire loading portion 2A. It is installed. Therefore, in order to make the fixing of the base plate 2 to the ground as complete as possible, the tire non-riding portion 2C is also provided with the anchor holes 3. In addition, as a means for fixing to the floor or the like, instead of the anchor or in combination, it is possible to adhere.

It should be noted that the protrusion 2B may be formed by bending, casting or forging an iron plate of 8 mm to 15 mm, for example. The cross-sectional shape, that is, the tire may have a substantially trapezoidal shape when viewed from the side, or a partial arc shape as shown in FIG. Each of them may be a solid product, but considering the increase in weight and reduction of material consumption, as shown in the figure, it is made hollow at the time of fillet welding both lower edges of the protrusion 2B to the base plate 2. Alternatively, when the protrusion 2B itself is manufactured, it may be formed into a cylindrical shape as shown by an imaginary line in FIG.

According to the tire stopper 1 having such a structure, the passenger car or the like can be kept immobile in the following manner. First, the tire stopper 1 as shown in FIG. 1 or 2 is placed on the asphalt pavement surface of the parking lot, and the anchor is passed through the anchor hole 3 and driven into the ground. When the ground is paved with concrete, vertical holes 4 are drilled to a certain depth on the ground surface and filled with mortar 4a, and the anchor holes 3 are aligned with the vertical holes 4 as shown in FIG. After that, drive the anchor 5.

Since the vehicle body may not be stopped in the center with respect to the parking space or a vehicle with a different vehicle width may enter, the length of the protrusion 2B in the left-right direction is set to, for example, twice the tire width or more. ing. Therefore, in such a case, the tire stoppers 1 are usually arranged one each on the left and right in the back of the compartment for one vehicle. It should be noted that the base plate 2 is lengthened to the left and right, and two protrusions 2B, 2B are fixed on one plate as shown in FIG. 4, or the base plate 2 having a long protrusion 2B (not shown) is substantially the same. It goes without saying that one tire stopper 1 will be installed if the width is set.

When a vehicle entering the parking lot enters a predetermined section, the vehicle enters until the rear wheel or front wheel 6 of the vehicle hits the protrusion 2B as shown in FIG. If the tire hits the protrusion 2B, the tire will ride on the tire mounting portion 2A at that time. As a result, some of the weight of the vehicle acts on the base plate 2 which is fixed to the ground. At that point, the base plate 2 will be pressed against the ground, and the frictional force between the lower surface of the base plate 2 and the ground will also increase. Of course, the base plate 2 is fixed by an anchor, but even if the vehicle slides on the base plate 2 for some reason, it is less likely that the tire stopper 1 will start moving due to the increased frictional force. .

By the way, although the example in which the tire non-riding portion 2C is secured to the side portion of the protrusion 2B on the base plate 2 has been described above, the tire stopper 1 is provided by the anchor hole 3 provided in the tire riding portion 2A. If the vehicle can be sufficiently fixed to the ground or the like, it is not always necessary to provide the tire non-riding portion 2C. The plane shape of the base plate 2 is not limited to the rectangular shape, and may have another contour such as a pentagon. If the base plate 2 is thick, the corners of the front edge of the base plate 2 may damage the tread of the tire. Therefore, a relatively large chamfer may be provided or an inclined surface 2a may be provided as shown in FIG.

In any tire stopper 1, if the protrusion 2B is manufactured separately from the base plate 2, the base plate 2 having different sizes and sizes can be used so as to suit the usage environment in the parking lot. It has the advantage that it can be attached in a fixed manner, and that it is easy to give flexibility to the setup for the production of the tire stopper.

When the tire stopper 1 is fixed to the upper floor of the multi-storey car park, bolts and nuts may be used. In that case, as shown in FIG. 6, it is possible to avoid exposing the heads of the bolts 7 or the like on the base plate 2 greatly by tilting them around the upper edge of the anchor hole 3. it can.

By the way, the protrusion 2B may be formed by bending so that a portion near the end of the base plate 2 is bulged upward as shown in FIGS. In such a case, generally, the thickness of the portion forming the base plate 2 and the thickness of the portion forming the protrusion 2B are often the same. However, in the case of manufacturing with reinforced plastic, it is easy to change the thickness from any place.

Further, it is preferable to secure the tire non-riding portion 2C with the protrusion 2B as a boundary in order to increase the rigidity of the tire stopper 1. Of course, it is also possible to attach the side plate member 8 as shown in FIG. 8 and reduce the deformation of the protrusion 2B. Such a side plate member 8 can be adopted also in the example shown in FIG.

In each of the above examples, the tire stopper 1 can be mounted on a flat surface of concrete or the like where sufficient reinforcement is provided, but the tire stopper 1 is installed in a parking lot such as an unpaved vacant land. Considering this, it is preferable to give the following consideration. For example, as shown in FIG. 9, a plurality of substantially needle-shaped spikes 9 are planted on the back surface of the base plate 2 by welding or the like. It is advisable to provide locking pawls 10 that are partially bent toward the ground as shown in FIG.

Needless to say, if the surface soil is gripped with the spikes 9 and the locking claws 10, the frictional force between the base plate 2 and the soil surface increases. Of course, the anchor holes 3 may be provided and the anchors may be driven in. If the spikes and locking pawls are long, it may be possible to reduce the number of anchors or not use them. When the anchor is not used, it is easy to change the installation location simply by lifting the tire stopper, which brings another advantage. In any of the examples, any protrusion can be used as long as it can hold the tire, and thus the contour shape, the wall thickness, and the like can be appropriately selected without being limited to the cross-sectional shape as described above.
