Abstract

<P>PROBLEM TO BE SOLVED: To provide a car stop block with a lifting function which prevents vehicles such as a truck and a bus parking with the car stop block from riding over the block even when a driver tries to start the vehicles while carelessly forgetting to remove the block, and which can be set and removed easily. <P>SOLUTION: The car stop block is configured to prevent a vehicle from advancing by means of a roller assembled in the car stop block, causing the vehicle wheel riding the roller to rotate idly. Furthermore, the car stock block is mounted with arms to allow the block to be entered under/removed from the wheel hydraulically, so that the weight of the block is not directly applied to hands even in a manual operation, with a reduction in labor. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to a car stop block that prevents a truck or other automobile from moving while parked.

  Trucks, trailers, buses, etc. are heavy, and the total weight of luggage and people on them is considerable, so it is sufficient that the brakes start moving when parked, especially on hills, if the brakes are loose It is conceivable that a driver often carries a car stop block (hereinafter referred to as a block) for safety. In particular, in the case of a large vehicle, the block itself is large and heavy, so it is quite difficult for the driver to remove the vehicle from the vehicle and carry it to the wheel, and perform the same work after use.

  In order to reduce such a hard work, a method of inserting a block between a wheel and a road surface using power can be considered, but it is not yet common. Looking at the ideas for car stops that have been conceived so far, there are many that have a complicated structure or are fixed to the road surface, and there are few small ones that can be carried with a simple structure. If a roller is used as a vehicle stop to prevent the wheel from moving forward, a small and effective one is possible. However, a roller is attached to a support device (see Patent Document 1) or a roller is attached. Some can be carried around (see Patent Document 2).

Japanese Patent Laid-Open No. 2003-13625 Noto 3106352 gazette

  The idea introduced in Patent Document 1 “Japanese Patent Laid-Open No. 2003-13625” is a car stop composed of almost only rollers, but the place of use is limited because it cannot be carried by a fixed road surface type. The thing introduced in Patent Document 2 “Joto No. 3106352” is similar to the present invention in that a roller is incorporated into a small vehicle stop that can be carried, but the difference from the present invention is that the lifting function is not provided. Is a point.

  The vehicle stop condition aimed by the present invention is small, light and effective, and can be loaded into a car and carried anywhere, and does not require a large amount of labor when installed on a wheel or removed.

  In order to solve the above-mentioned problem, the idea of claim 1 is that a car stop block having one of six faces constituting a rectangular parallelepiped as a slope, and a roller is incorporated in the block of the slope portion in parallel with the road surface. A part of the outer peripheral surface of the block protrudes on the slope, or on the slope and the upper surface at the same time, and an arm for moving the block is attached to the block body, and it is stored and held in the car body when the block is not used. It is a vehicle stop block with a raising / lowering function characterized by these.

  Since large trucks are heavy and there is a possibility that they will get over the block once it starts moving while parked and stopped, it is necessary to use a block that is as large as possible in terms of safety. However, if it is too large, the work of inserting between the wheel and the road becomes difficult, so it is desirable to keep it to a certain size. Therefore, in the present invention, the block itself is not so large, and a roller is incorporated on the slope where the wheel of the block hits to prevent the vehicle from moving forward because the wheel idles on the roller even if the wheel tries to get over. At the same time, in order to reduce the labor of the driver, when inserting and removing the block, it is not necessary to do everything manually, but using hydraulic pressure or lifting manually while supporting the weight with an arm. Adopted a method to reduce.

  The inclination angle of this trapezoidal block slope may prevent the wheels from getting over in order to prevent the movement of the car, but for example, if the angle with the road surface is increased to near right angle, It is not necessarily effective. In other words, although it is difficult for the wheel to get over the block, the carrying block does not exert a force to press against the road surface, and there is a risk that the wheel will slip forward if the block slips. Therefore, it is necessary to set an appropriate angle at which the block can enter under the wheel so as to exert a force for pressing the road surface and an angle at which it is difficult to get over. As an angle satisfying this condition, 40 to 50 degrees seems to be appropriate.

  As the block material, metal such as iron or stainless steel with a hollow inside is suitable from the viewpoint of strength, durability, and weight reduction, but there is no big problem even if it is made of wood.

  The block is usually applied to driving wheels such as a truck, but if you forget to remove it after use and leave the vehicle, an accident that damages the arm will naturally occur. By attaching a roller to the block, it is possible to prevent the wheel from idling on the roller and getting over the block even when the wheel is driven. In that sense, in the present invention, the arm mounting block and the roller should be considered as an inseparable integral.

  As for the material of the roller, metallic is desirable from the viewpoint of strength and durability, but if the central shaft and bearing to which force is applied are made of metal, there is no problem even if the hard part of the roller is used for the roller rotating part. Seem.

  Although it is an arm attached to a block, it needs to have sufficient strength to move the block, and is preferably made of iron or other metal. As a method of inserting and removing from the lower part of the wheel and storing it in the vehicle body, it is easy to use a piston-type hydraulic drive, but it can be rotated around the fulcrum center of the upper end of the arm, or the arm can be folded to wire Alternatively, it may be manually moved up and down using a chain. The point to be noted is that it is stored and held in the vehicle body and needs to be fixed with a chain or other fastener so as not to drop due to vibration during traveling. The location where the block is operated may be controlled from the driver's seat, but it is desirable to operate while looking at the interrelationship between the wheel and the block. It is better to be able to operate.

  There are several possible ways to attach the arm to the block. However, if the arm is fixed to the block at a fixed position, there may be a case where the arm cannot fit well between the road surface and the wheel. Therefore, if a through hole with a long and narrow entrance is made in the block part that does not interfere with the built-in roller, and a connecting rod that connects the two arms is inserted there, the installation angle of the block can be freely changed, and the block can be moved up and down freely. Therefore, it is possible to smoothly install and store the block on the wheel of the block without interfering with the road surface, the fender of the car, and other vehicle accessories.

  Furthermore, in order to solve the above-mentioned problem, the idea of claim 2 is that, in a car stopper block having a shape of a triangular prism that is laid down, a roller is incorporated in the block of the slope portion in parallel with the road surface, 2. The vehicle stop block with an elevating function according to claim 1, wherein the portion protrudes on the slope, or simultaneously protrudes on the slope and the apex of the triangle.

  Even if the shape of the block is a triangular prism, the function of the block can be sufficiently achieved if the angle of the slope is set to the angle described in claim 1 and the road surface can be firmly grasped. There is no need for such severe restrictions, and any other shape that can exhibit the above-described function can be used even in other shapes such as a trapezoid or a triangular prism. It can be said that the triangular prism is rather excellent in that the weight of the block can be reduced.

  About the material of a triangular prism or a roller, there is no problem by using metals, such as iron and stainless steel, or wood like the block mentioned above.

  If the driver forgets to remove the car stop and parks after stopping, the driving wheel rotates and tries to get over the block, but because the roller is built in the block, the wheel is It spins on the roller and does not get over the block. If the roller is not installed, it is possible that the wheel will get over the block and break the arm, but thanks to the installed roller, it is a car stop that covers the driver's carelessness. Furthermore, in this proposal, the arm is attached to the block and attached to the vehicle body, and the arm is lifted and lowered by hydraulic drive, or the block is lifted and lowered by hand while being supported by the arm.

The perspective view of the vehicle stop block whose side shape is trapezoid. The side partial perspective view of a vehicle stop block. The side view which shows one Example of the manual block raising / lowering of the track | truck which has a vehicle body side surface lower part in a high position from a road surface. (The illustration of the roller with built-in block is omitted in both Fig. 4 and Fig. 5) The side view which shows one Example of the block raising / lowering in a bus, a passenger car, etc. in which the vehicle body side lower part is in a low position from the road surface. FIG. 5 is a side view showing an embodiment in the case where the lowering of the side of the vehicle body is performed at a low position as in FIG. (Hydraulic circuit not shown) The perspective view of the car stopper block whose shape is a triangular prism.

  The present invention is a vehicle stop block having the above-described structure. When this block is used, the following procedure is used. When block 1 is necessary to park or park a truck or the like on a sloping ground, block 1 is usually applied only to the lower side of wheel 9, but if it is recognized that the vehicle needs to be fixed under strong wind, etc. It is possible to use block 1 before and after 9. In the embodiment shown in the drawings (FIG. 3, FIG. 4, FIG. 5), for convenience, two blocks 1 are used at the same time. 1 and 6, two arms 3 are used for one block 1. However, it is possible to use only one arm 3 on one side depending on the strength of the arm 3 and the weight of the block 1. It is.

  FIG. 3 shows an embodiment where the distance between the vehicle body 10 and the road surface is long, such as a large truck. Since the distance from the vehicle body 10 to the road surface is long, the stay 5 is extended downward from the vehicle body, and its tip is used as a fulcrum for arm attachment. The operator of the block 1 operates the handle of the hoisting machine 6 to loosen the wire 7, removes the fastener A8a fixing the block 1, and when the block 1 reaches the road surface due to gravity, picks up the block 1 and picks the wheel Insert between 9 and the road surface. On the other hand, when the block 1 is stored and held in the vehicle body 10, the procedure is reversed. First, the block 1 is held in the hand, the arm 3 is passed to a position where the arm 3 is located at an angle on the opposite side of the wheel 9 past the vertical position, the hand is stopped, and the winding machine 6 is manually operated to wind up the wire 7. When the block 1 and the arm 3 come to the top dead center, the winding is stopped and the fastener A8a is fixed to the through hole 4 of the block 1.

  The embodiment of FIG. 4 is an example when the distance between the vehicle body 10 such as a bus and the road surface is short. In this case as well, all the steps are performed manually. First, the fastener B8b is removed, and the block 1 and the arm 3 are held in the hand and directly applied between the wheel 9 and the road surface. When storing and holding in the vehicle body 10, the reverse procedure is performed.

  FIG. 5 shows a device for moving the block 1 up and down by a hydraulically driven piston 11, but by operating a lever (not shown) installed near the driver's seat or the wheel 9, a vehicle stop is inserted between the wheel 9 and the road surface. . When the vehicle body 10 is stored and held, all the reverse is performed only by operating the lever, and operations such as moving the block 1 by hand are not required. When the block 1 is stored and held, it is firmly fixed to the vehicle body 10 with a fastener C8c such as a chain.

  The usage method of the triangular prism block 1 shown in FIG. 6 is exactly the same as the case of FIGS. 3 and 4 shown above except that the shape of the block 1 is different. However, in FIG. 6, illustration of the through hole is omitted. If the attachment of the triangular block 1 to the arm 3 is fixed as shown in FIG. 6, it is possible to use the hydraulic drive piston 11 as shown in FIG.
