Description

  The present invention relates to a foldable car stopper that can be folded during storage.

  When parking a large vehicle such as a bus or truck, a driver holds a triangular prism-shaped stopper between the front and rear of the tire and the ground to prevent the vehicle from inadvertently moving.

  Generally, a car stopper device in which a pair of stoppers are connected by a rope is used. However, such a conventional car stop device has a problem that the driver has to bend his / her waist deeply and insert a stopper between the tire and the ground, and the work posture is unnatural and a burden is placed on the waist. There was also a risk of dirty hands.

  Therefore, the present inventors have provided triangular prism-shaped stoppers on the left and right sides of the main body with a grip on the upper part, and the driver can insert the stopper between the tire and the ground without bending the waist deeply. A car stopper device that can be folded when in use was first devised and proposed as Patent Document 1.

  However, since the car stopper of Patent Document 1 uses the rack and pinion mechanism to rotate the left and right triangular prism stoppers, there is a possibility that sand and pebbles may be caught in the rack and pinion mechanism depending on the parking location. It was.

  Accordingly, an object of the present invention is to solve the above-described conventional problems, and to provide a foldable car stopper that can be folded compactly when not in use and is difficult to bite sand and pebbles.

  A foldable car stopper according to the present invention made to solve the above-mentioned problems includes a main body that stands upright with respect to the ground, left and right arms that can be extended and contracted on both sides with respect to the main body, and tips of these arms. , A triangular prism-shaped ring stopper attached via a shaft, a telescopic link mechanism mounted between these left and right ring stoppers, a spring that springs in the direction of expanding the link mechanism, and both lower sides of the main body And a curved rail for rotating the triangular pole-shaped ring stopper between the use state and the folded state.

  As in claim 2, it is preferable to provide the main body with a stopper mechanism that holds the left and right arms in a position retracted toward the center, and as in claim 3, the link mechanism is a pantograph mechanism, It is preferable to provide a handle for operating the pantograph mechanism in a direction to retract the link mechanism.

  The foldable vehicle stop device of the present invention does not use a rack and pinion mechanism like the vehicle stop device of Patent Document 1, and has a structure in which the stopper is rotated while being guided by the curved rail, and therefore has an advantage that sand and pebbles are not easily caught. . Further, the link mechanism that can be expanded and contracted can be easily opened and closed, and can be folded compactly when not in use.

It is a front view of the folding-type car stopper of an embodiment. It is a front view which shows a use condition. It is a top view which shows the folding state of the folding-type car stopper of embodiment. It is sectional drawing which shows an example of a stopper mechanism.

Embodiments of the present invention will be described below.
FIG. 1 is a front view showing a use state, in which 10 is a main body having a grip 11 at the top. The main body 10 extends in the vertical direction, and a base 12 is provided at the lower end so that it can stand upright with respect to the ground.

  A pair of hollow guides 13 extending in an oblique direction are attached to the front and back surfaces of the main body 10 in an X shape, and left and right arms 14 are supported by these hollow guides 13 so as to be extendable and contractible. In the use state shown in FIG. 1, the left and right arms 14 are in a state of extending to the left and right. As shown in FIG. 1, these arms 14 extend in the direction in which the tips approach the ground.

  At the tip ends of these left and right arms 14, a triangular prism-shaped ring stopper 16 is pivotally supported by a shaft 15. The triangular pillar-shaped ring stopper 16 is preferably a right triangle, and in FIG. 1, one side 17 sandwiching the right angle is in a position in contact with the ground, and the hypotenuse 18 is in a position in contact with the tire 50 as shown in FIG.

  A telescopic link mechanism 19 is provided between the shafts 15 of the left and right wheel stops 16. In this embodiment, the link mechanism 19 is a pantograph mechanism. The central portion of the pantograph mechanism is attached near the lower portion of the main body 10 by a shaft 20.

  The link mechanism 19 is provided with a spring 21 that springs in a direction to expand the link mechanism 19 and a pair of handles 22 for moving the link mechanism 19 in a contracting direction. By expanding and contracting the link mechanism 19, the distance between the left and right wheel stops 16, 16 can be changed and folded or expanded.

  In addition, curved rails 23 are provided on the left and right of the lower end of the main body 10. The curved rail 23 is in contact with the pin 24 at the tip of the hypotenuse 18 of the triangular prism-shaped ring stopper 16 to rotate the wheel stopper 16 between the use state and the folded state. The pin 24 can also be a roller.

  Stopper holes 25 are formed in the left and right arms 14, and the left and right arms 14 can be held in the retracted state of FIG. 3 by inserting stopper pins 26 provided in the main body 10. The stopper pin 26 may be manually inserted / removed, but in this embodiment, a stopper mechanism is employed in which the stopper pin 26 is retracted by pulling a puller 27 provided on the grip 11.

  FIG. 4 is a sectional view showing an example of the stopper mechanism. Inside the main body 10, a pair of stopper pins 26 are provided so as to be able to protrude and retract, but these stopper pins 26 are elastically retreated by a spring 32. Rollers 28 are provided at the rear end of the stopper pin 26, and these rollers 28 are in contact with a triangular cam 29. The cam 29 is provided at the lower end of a stopper bar 30 that can be raised and lowered inside the main body 10, and the stopper bar 30 is always springed downward by a spring 31 stronger than the spring 32.

  For this reason, the pair of stopper pins 26 are pushed by the cam 29 and are always pushed outward. However, when the left and right arms 14 are extended as shown in FIG. Since it has moved from the position, the stopper pin 26 is in the retracted position. However, as shown in FIG. 3, when the left and right arms 14 are contracted, the stopper hole 25 of the arm 14 comes to the position of the stopper pin 26. Therefore, the stopper pin 26 is inserted into the stopper hole 25 of the left and right arms 14 as shown in FIG. Inserted. As a result, the folded state is maintained. However, when the puller 27 at the upper end of the stopper rod 30 is pulled up against the spring 31, the stopper pin 26 is retracted inward and the left and right arms 14 are moved by the force of the spring 21. It becomes the state of.

  The foldable vehicle stop device of the present invention configured as described above is used by inserting the left and right wheel stops 16 and 16 into both sides of the tire 50 as shown in FIG. 3 in an open state as shown in FIG. . For this reason, the left and right wheel stoppers 16 extend in the depth direction of the paper surface.

  After use, the link mechanism 19 is contracted by grasping the left and right handles 22. With this movement, the pins 24 of the left and right wheel stops 16 are guided by the curved rails 23 and moved upward, and the wheel stops 16 rotate around the shaft 15 in the direction indicated by the arrow B in FIG. In addition, in this way, the foldable car stopper of the present invention can be folded compactly as shown in FIG. Simultaneously with the folding, the stopper pin 26 is inserted into the stopper holes 25 of the left and right arms 14, and the folded state is maintained.

  When the pulling hand 27 is pulled during use, the stopper pin 26 moves backward, so that the left and right arms 14 are expanded to the left and right by the force of the spring 21 and the use state of FIG. At this time, it is only necessary to operate the handle 27 at the upper end of the main body 10, so there is no need to bend down and insert the stopper between the tire 50 and the ground as in the prior art.

  As described above, the folding car stopper of the present invention does not use a conventional rack and pinion mechanism for rotating the left and right wheel stoppers 16, and therefore causes malfunction due to biting sand or pebbles. There is no. In addition, after use, it can be folded and stored compactly, and there are many advantages such as no need to take an unnatural posture during use.
