Description

[Technical Field]

[0001] The present invention relates to a vehicle forced stop device. [Background technology]

[0002] When lane restrictions are implemented during road construction, vehicle forced stop devices are sometimes placed on the road to forcibly stop vehicles in case they accidentally enter the road (Patent Document 1, Patent Document 2).

[0003] Such a vehicle forced stop device mainly comprises a base portion, a vehicle stop portion, and a vehicle landing portion. The vehicle landing portion comprises a plurality of leg members. Each leg member comprises a leg body, a flange member fixed to a first end of the leg body, and a locking member fixed to a second end of the leg body. When the vehicle forced stop device is in use, the flange member is placed on the road and the locking member is engaged with the vehicle stopping portion. When a vehicle runs onto the vehicle landing portion or collides with the vehicle stopping portion, a load is applied to the base portion and the leg members. The frictional force of the base portion and the leg members against the road restricts movement of the vehicle forced stop device, allowing the vehicle to be forced to a stop.

[0004] [Patent Document 1] Utility Model Registration No. 3137897 [Patent Document 2] Utility Model Registration No. 3222426 Summary of the Invention [Problem to be solved by the invention]

[0005] Conventional leg members are manufactured by cutting both ends of a square pipe that constitutes the leg body to fit the shapes of the flange member and locking member, and then welding the flange member and locking member to each end of the leg body. However, when manufacturing leg members by cutting or welding, the lengths of each leg member vary. As a result, there is a risk that parts of the base or parts of the leg member do not make sufficient contact with the road, and the braking force of the vehicle stopping device is not fully exerted.

[0006] An object of the present invention is to provide a vehicle forced stop device with improved braking force. [Means for solving the problem]

[0007] The present invention provides the following aspects. (Item 1) A base portion; a vehicle stopper extending from the base; a vehicle climbing portion having a plurality of leg members movable relative to the vehicle stop portion between an unfolded position and a folded position; Equipped with Each leg member is a leg body made of a hollow member having a first end and a second end opposite the first end; A first connecting member; a flange member, which is a molded product, connected to the first end of the leg body by the first connecting member and placed on a road in the deployed position; A second connecting member; a locking member that is a molded product and is connected to the second end of the leg body by the second connecting member and is engaged with the vehicle stopper in the deployed position; A vehicle forced stop device comprising:

[0008] (Item 2) One of the leg body or the flange member includes a first insertion portion; the other of the leg body and the flange member includes a first accommodating portion into which the first insertion portion is inserted, The first insertion portion is inserted into the first accommodating portion and is connected to the other of the leg main body and the flange member by the first connecting member. Item 1: A vehicle forced stop device.

[0009] (Item 3) One of the leg body or the locking member includes a second insertion portion; the other of the leg body and the locking member includes a second accommodating portion into which the second insertion portion is inserted, the second insertion portion is inserted into the second accommodating portion and is connected to the other of the leg main body and the locking member by the second connecting member; A vehicle forced stop device according to item 1 or 2. [Effects of the Invention]

[0010] The vehicle stop device of the present invention uses flange members and locking members manufactured with high precision by molding. Furthermore, the flange members and locking members are connected to the leg body by first and second connecting members, rather than by welding. This eliminates the need to cut both ends of the hollow member that makes up the leg body or to weld flange members and locking members to both ends of the leg body, allowing leg members of uniform length and angle to be obtained. This allows the back surfaces of the base and all flange members to fully contact the road, thereby increasing the frictional force of the base and flange members against the road. As a result, the braking force of the vehicle stop device can be improved. [Brief explanation of the drawings]

[Figure 2] 1A is a side view of a vehicle forced stopping device in an unfolded position, and FIG. 1B is a side view of a vehicle forced stopping device in a folded position. [Figure 3] FIG. 3(a) is an exploded perspective view of the leg member, and FIG. 3(b) is a cross-sectional view taken along line IIIb-IIIb in FIG. DETAILED DESCRIPTION OF THE INVENTION

[0012] A vehicle forced stop device 10 of the present invention will be described with reference to the drawings.

[0013] <1. Structure of the vehicle forced stop device> The vehicle forcible stopping device 10 is a device that is installed on a road and forcibly stops a vehicle that erroneously enters the road. As shown in FIG. 1, the vehicle forcible stopping device 10 includes a base portion 1, a vehicle stop portion 2, a vehicle climbing portion 3, and a link rod 4. The vehicle forcible stopping device 10 is capable of being transformed between an unfolded position (see FIGS. 1 and 2(a)) in use and a folded position (see FIG. 2(b)) in non-use.

[0014] The base unit 1 is the part that is placed on the road and restricts the movement of the vehicle forced stop device 10 by friction with the road. The back surface of the base unit 1 (i.e., the surface that comes into contact with the road) preferably has a resistance part for increasing the friction with the road. The resistance part can be formed, for example, by attaching a high-friction material such as rubber to the back surface of the base unit 1 or by providing irregularities on the back surface of the base unit 1.

[0015] The vehicle stopper 2 is a portion that contacts the front of the vehicle to stop the vehicle. As shown in FIG. 1, the vehicle stopper 2 includes a plurality of pillar members 21 and a plurality of pillar connecting members 22 (22a, 22b). The pillar members 21 are arranged parallel to one another. Each pillar member 21 is fixed to the base 1 and stands upright from the base 1. The pillar connecting members 22 are arranged between the pillar members 21 and connect the pillar members 21 together. A protrusion 23 is provided on the outer surface of one of the pillar members 21 (the pillar member 21 on the front side in FIG. 1) at approximately the same height as the lower pillar connecting member 22b. As will be described later, when the vehicle forced stop device 10 is in use, a locking member 314 of the vehicle climbing portion 3 is engaged with the lower pillar connecting member 22b and the protrusion 23.

[0016] The vehicle climbing section 3 is a portion that is positioned below the vehicle when the front wheels of the vehicle climb up on it. As shown in Fig. 1, the vehicle climbing section 3 includes a plurality of leg members 31 and a leg connecting member 32. The leg connecting member 32 connects the plurality of leg members 31 together.

[0017] As shown in Figure 2, the vehicle climbing portion 3 is connected to the base portion 1 by a link rod 4 and is movable relative to the vehicle stopping portion 2 between an unfolded position (see Figure 2(a)) and a folded position (see Figure 2(b)).

[0018] As shown in FIG. 3, each leg member 31 includes a leg body 311 , a flange member 312 , a first connecting member 313 , a locking member 314 , and a second connecting member 315 .

[0019] The leg body 311 is made of a metal square pipe equipped with a reinforcing plate 3111, and the internal space is divided into multiple spaces by the reinforcing plate 3111. As will be described later, the internal space of the leg body 311 functions as a housing section for housing the first insertion portion 3122 of the flange member 312 and the second insertion portion 3142 of the locking member 314.

[0020] The flange member 312 is a molded product (cast product) made of a metal material. The flange member 312 includes a flat flange main body 3121 and a first insertion portion 3122, and is connected to a first end of the leg main body 311. The back surface of the flange main body 3121 comes into contact with the road when the vehicle forced stop device 10 is installed on the road. The back surface of the flange main body 3121 preferably includes a resistance portion for increasing friction with the road. The resistance portion of the flange main body 3121 may have the same configuration as the resistance portion of the base unit 1. The first insertion portion 3122 protrudes from the flange main body 3121. The first insertion portion 3122 is inserted into the internal space of the leg main body 311 and connected to the leg main body 311 by a first connecting member 313. The first connecting member 313 is, for example, a bolt.

[0021] The locking member 314 is a molded product (cast product) made of a metal material. The locking member 314 includes a locking body 3141 and a second insertion portion 3142, and is connected to the second end of the leg body 311. The locking body 3141 includes a notch 3141a for inserting the lower pillar connecting member 22b or the protrusion 23 of the vehicle stopper 2. The lower pillar connecting member 22b or the protrusion 23 is accommodated in the notch 3141a, thereby locking the leg body 311 to the vehicle stopper 2. The second insertion portion 3142 protrudes from the locking body 3141. The second insertion portion 3142 is inserted into the internal space of the leg body 311 and connected to the leg body 311 by a second connecting member 315. The second connecting member 315 is, for example, a bolt.

[0022] <2 Vehicle stopping mechanism> The mechanism by which the vehicle forcible stopping device 10 stops the vehicle will be described.

[0023] If the vehicle is primarily a small vehicle, when the front wheels of the vehicle run onto the vehicle run-up section 3, the vehicle forced stop device 10 slides along the road together with the vehicle. The mass of the vehicle on the vehicle run-up section 3 presses the base portion 1 and flange main body 3121 against the road. This creates a strong frictional force between the road and the base portion 1 and flange main body 3121, causing the vehicle forced stop device 10 and the vehicle to slow down and come to a stop.

[0024] When a vehicle is primarily a medium-sized vehicle, the front wheels of the vehicle run onto the vehicle run-on section 3, and then the vehicle collides with the vehicle stop section 2. From the time the front wheels of the vehicle run onto the vehicle run-on section 3 until the vehicle collides with the vehicle stop section 2, the mass of the vehicle presses the base section 1 and flange main body 3121 against the road, creating a strong frictional force between the road and the base section 1 and flange main body 3121. This allows the vehicle forced stop device 10 and the vehicle to decelerate. Furthermore, after the vehicle collides with the vehicle stop section 2, the vehicle stop section 2 falls in the vehicle's direction of travel, and the vehicle forced stop device 10 rotates in the vehicle's direction of travel so that the flange main body 3121 is lifted off the road. As the vehicle forced stop device 10 rotates in the vehicle's direction of travel, the base section 1 is pressed strongly against the road due to the principle of leverage, increasing the frictional force of the base section 1 against the road. As a result, the vehicle forced stop device 10 and the vehicle can be further decelerated and stopped.

[0025] When the vehicle is primarily a large vehicle, i.e., when the distance from the front of the vehicle to the front wheels is greater than the distance from the vehicle stopper 2 to the rear end of the vehicle run-on section 3, the vehicle will collide with the vehicle stopper 2 without the front wheels running onto the vehicle run-on section 3. At the moment the vehicle collides with the vehicle stopper 2, the vehicle forced stop device 10 and the vehicle can be decelerated due to the frictional force between the road and the base unit 1 and flange main body 3121. After the vehicle collides with the vehicle stopper 2, the vehicle stopper 2 tilts in the vehicle's traveling direction, and the vehicle forced stop device 10 rotates in the vehicle's traveling direction so that the flange main body 3121 is lifted off the road. By rotating the vehicle forced stopper 10 in the vehicle's traveling direction, the base unit 1 is pressed firmly against the road due to the principle of leverage, increasing the frictional force of the base unit 1 against the road. As a result, the vehicle forced stop device 10 and the vehicle can be further decelerated and stopped.

[0026] <3 Features> The vehicle stop device 10 of the present invention uses flange members 312 and locking members 314 manufactured with high precision by molding. Furthermore, flange members 312 and locking members 314 are connected to leg body 311 by first connecting members 313 and second connecting members 315, respectively, rather than by welding. This eliminates the need to cut both ends of the square pipe constituting leg body 311 or to weld flange members 312 and locking members 314 to leg body 311, as in the past. This allows leg members 31 to be manufactured with uniform lengths and angles. This allows the back surfaces of flange members 312 of all leg members 31 to fully contact the road, thereby increasing the frictional force of each flange member 312 against the road. As a result, the braking force of vehicle stop device 10 can be improved when the front wheels of the vehicle run over run-up section 3 and at the moment the vehicle collides with vehicle stop section 2. Furthermore, because each leg member 31 has a uniform length and angle, the load is applied evenly to the base unit 1 and the load transmission efficiency is improved, thereby increasing the frictional force of the base unit 1 against the road. As a result, the braking force of the vehicle forced stopping device 10 can be improved when the front wheels of the vehicle run onto the run-on portion 3, when the vehicle collides with the vehicle stop portion 2, and also when the vehicle rotates in the direction of travel of the vehicle.

[0027] <4 Variations> The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the present invention. The present invention can be modified, for example, as shown in the following modifications. The modifications described below can be combined as appropriate without departing from the spirit of the present invention.
