Modes for Carrying Out the Invention

[0011] Hereinafter, modes for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the front and left side of the vehicle forced stop device 1, and FIG. 2 is a perspective view showing the front and right side of the vehicle forced stop device 1 according to the present embodiment. The vehicle forced stop device 1 includes a base portion 3 provided with a grounding member (elastic plate) 2 in contact with the road surface on the back surface thereof, a vehicle stop means 4 made of a columnar steel material pivotally supported at the lower end by the base portion 3, a rod-shaped link member 5 pivotally supported at the base end by the base portion 3, and a vehicle mounting means 6 made of a shaped steel material. The vehicle mounting means 6 has a leg tip portion 7 in contact with the road surface provided at one end side in the longitudinal direction, an engaging means 8 with the vehicle stop means at the tip side which is the opposite end of the leg tip portion 7, and a support means 9 for pivotally supporting the tip of the link member 5 at approximately the middle. Further, a holding means 10 is provided between the vehicle stop means 4 and the engaging means 8 to maintain the engaged state of the two in a detachable manner when folded.

[0012] The grounding member 2 provided on the back surface of the base portion 3 has a structure shown in FIG. 4 which will be described in detail later. The grounding means 2 is an elastic plate formed of synthetic rubber and is molded with a steel plate 20 provided inside as a core material. In this embodiment, three vehicle stop means 4 are arranged side by side, and the lower ends of each vehicle stop means 4 are pivotally supported at bearing portions 15 provided on the upper surface of the base portion 3 respectively. The bearing portion 15 is formed by a pair of flange plates arranged opposite to each other, and the lower end of each vehicle stop means 4 and the base end of the link member 5 are pivotally supported by a shaft member 16 suspended through both flange plates.

[0013] Each vehicle stop means 4 is formed of a columnar shaped steel material and has a strength capable of receiving the collision of the vehicle. The base portion 3 has a structure in which individual bearing portions 15 pivotally supporting three vehicle stop means 4 arranged in parallel are integrally connected, so that all shaft members 16 are arranged on the same axis. Further, the three vehicle stop means 4 are firmly connected by connecting frames 17, 18 connecting each other near the middle and near the upper part to form a rigid body.

[0014] The tip of the rod-shaped link member 5 pivotally supported at the base end by the shaft member 16 of the base portion 3 is pivotally supported by a support means 9 provided at approximately the middle position of the vehicle mounting means 6. The vehicle boarding means 6 is a long-axis-shaped profiled steel material, and a leg tip portion 7 that contacts the road surface is provided at one end side in the longitudinal direction. A grounding body 21 having a plate-like appearance formed of synthetic rubber is attached to the back surface of the leg tip portion 7. The grounding body 21 is formed with a steel plate 22 provided inside as a core material.

[0015] The engaging means 8 provided at the tip of the vehicle boarding means 6 that engages with the vehicle stopping means 4 has a U-shaped inner wall surface that contacts so as to cover the left and right side surfaces and the front surface, which are the outer shapes of the vehicle boarding means 6. The engaging means 8 has an engaging groove 25 that engages with the connecting frame 17 that connects the vehicle stopping means 4 from above. When the connecting frame 17 and the engaging groove 25 engage with each other, the vehicle boarding means 6 supports the tilting of the vehicle stopping means 4. Note that an engaged portion 26 protrudes from the outer surface of the vehicle stopping means 4 without the connecting frames 17 arranged on both sides, and the engaging groove 25 engages in the same manner as it engages with the connecting frame 17.

[0016] Also, a lock pin 27 that penetrates both the connecting frame 17 and the vehicle stopping means 4 is provided so as to be insertable and removable. The tip of the lock pin 27 engages with a retaining lever 28 provided on the connecting frame 17, and the inserted state is maintained by engaging with the retaining lever 28. In this way, since the lock pin 27 is held by the retaining lever 28, even when it receives an impact due to a collision of the vehicle, the lock pin 27 does not fall out and the engagement between the vehicle stopping means 4 and the vehicle boarding means 6 is not released, and the function as the vehicle forced stop device 1 is maintained.

[0017] As described above, the engagement between the vehicle stopping means 4 and the vehicle boarding means 6 has a double engagement release prevention means, namely, the lock pin 27 and the retaining lever 28 that prevents the lock pin from coming out. Note that although the locking pin 27 and the retaining lever 28 are adopted as optimal means, there are numerous alternative means, and it goes without saying that the present invention is not limited to the above examples.

[0018] FIG. 3 is an external perspective view of the vehicle forced stop device 1 in a folded state. When the engaging means 8 is removed from the vehicle stopping means 4, the vehicle mounting means 6 can rotate freely about the shaft member 30 provided as the supporting means 9 at the tip of the link member 5, and can be folded on top of the vehicle stopping means 4. On the upper part of the vehicle stopping means 4 (4a) arranged at the center, there is provided a rotatable plate-shaped retaining means 10 having a hook-shaped groove at its tip. The hook-shaped groove of the retaining means 10 engages with the protrusion 31 provided on the outer surface of the engaging means 8 at the tip of the vehicle mounting means 6, so that the engaging means 8 at the upper part of the vehicle stopping means 4 (4a) can be maintained in a close state. That is, it has the function of maintaining the folded state of the vehicle stopping means 4 and the vehicle mounting means 6.

[0019] The engagement between the retaining means 10 and the protrusion 31 is performed at the end portions of the vehicle stopping means 4 and the vehicle mounting means 6. This position is a part where less force is required to maintain the folded state, so that locking can be effectively performed even with less force acting on the retaining means 10 and the protrusion 31. Also, the fact that less force is required means that there is an effect that damage to the members constituting the locking mechanism is less likely to occur.

[0020] FIG. 4(a) is an explanatory view showing the appearance of the grounding means (elastic plate) 2 formed of synthetic rubber, and FIG. 4(b) is a partial cross-sectional view showing the steel plate arranged inside the grounding means 2. The grounding means 2 is an elastic plate having a rectangular plate-like appearance, and is provided with a plurality of holes 33 penetrating through from the front to the back. The grounding means 2 is screwed to the back surface of the base portion 3 using the holes 33. The conventional grounding means was a plate made of only synthetic rubber without a built-in steel plate, but it was easily damaged by repeated use. However, by incorporating the plate 20 and forming it integrally, it became possible to improve the durability.

[0021] FIG. 5(a) is an explanatory diagram showing the appearance of a grounding body (elastic plate) 21 attached to the bottom surface of the leg tip portion 7 formed of synthetic rubber, and FIG. 4(b) is a partial cross-sectional view showing the plate 22 disposed in the grounding body 21. The grounding body 21 is an elastic plate having a rectangular outer shape, and is provided with a plurality of holes 34 penetrating through from front to back. The grounding body 21 is screwed to the back surface of the leg tip portion 7 at the tip using the holes 34. The conventional grounding means was a plate made of only synthetic rubber without a built-in steel plate, so it was easily damaged by repeated use. However, by integrally forming it with a built-in steel plate, it became possible to improve the durability.

[0022] As another structure, the vehicle forced stop device 1 has casters 35 below and a handlebar 36 above so that it can be transported when folded. Although one embodiment of the present invention has been described above, general well-known techniques and well-known techniques may be appropriately adopted without departing from the gist of the invention described in the scope of utility model registration claims.
