Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle collision buffering device which is placed on a road surface in order to prevent a vehicle from jumping into and entering a prohibited area for vehicles, and which causes the vehicle to suddenly stop by colliding with or riding on it. It is a thing.

[0002]

2. Description of the Related Art Conventionally, for example, a road construction site,
In order to prevent a single accident or personal injury due to a vehicle jumping into an area where vehicles cannot enter, water drums, sandbags, and other obstacles are placed at both ends of the area where no entry is allowed on the road surface. It is installed with detour signs such as safety cones.

However, when the vehicle actually jumps in and collides with these obstacles, it is flipped or collapsed and it is difficult to safely stop the vehicle suddenly.

Therefore, at present, a vehicle collision cushioning device in which a sheet-like portion is integrally extended from a cushioning body using a cushioning material such as urethane resin toward an entering vehicle along the approaching direction. Is being developed.

In this collision damping device, an automobile that has accidentally entered the vehicle collides with the cushioning body after traveling on the sheet-shaped portion. At the time of this collision, since the sheet-shaped portion is pressed against the road surface by the vehicle that is still on the sheet-shaped portion, the cushioning body that is integral with the sheet-shaped portion is flipped off by the collision of the vehicle. Instead, they are shocked and deformed on the spot, and the car is ridden and stopped.

[0006]

As described above, even if the device using the cushioning material is lightweight, the integral extension member prevents the device from being flipped off at the time of collision with the vehicle and absorbs the impact. Then, the vehicle can be stopped safely.

The use of the collision damping device having such a structure is as follows.
It is considered to be popular because it is easy to secure the safety of workers, traffic controllers, and motorists in areas where vehicles are prohibited to enter, such as road construction sites. There is a demand for a structure that can be easily installed, that has excellent durability, and that that can be partially replaced so that the device as a whole can last a long time and that can reduce costs.

In view of the above problems, an object of the present invention is to stop the vehicle safely and surely using a cushioning material, and
An object of the present invention is to provide a vehicle collision damping device having a simple and easy assembly and installation work.

It is another object of the present invention to provide a vehicle collision damping device which is partially replaceable, can reduce costs, and has excellent durability.

[0010]

In order to achieve the above object, a vehicle collision damping device according to a first aspect of the present invention is provided.
A cushioning main body that is placed on a road surface and deforms due to a collision of the vehicle to cushion the impact on the vehicle and stops the vehicle, and a seat member that is stepped on by the vehicle during the collision, The sheet member has a branch portion at one end and a double structure portion extending from the branch portion to form a stack of two sheets vertically, and with the cushioning body sandwiched between the sheets of the double structure portion. The upper and lower sheets are joined to the open end of the double structure so as to be releasably joined to each other.

A vehicle collision damping device according to a second aspect of the present invention is the vehicle collision damping device according to the first aspect, wherein the cushioning main body includes a cushioning member and a packaging member that encloses the cushioning member. An air vent hole is provided in the packaging member on the exposed surface of the buffer main body other than the area sandwiched by the upper and lower sheets of the double structure.

A vehicle collision damping device according to a third aspect of the present invention is the vehicle collision damping device according to the first or second aspect, wherein the cushioning member has one or more hollow portions. It is a feature.

Further, a vehicle collision damping device according to a fourth aspect of the present invention is the vehicle collision damping device according to the first aspect, wherein the seat member has a tare portion in which a weight is removably housed. It is characterized by having at least one.

In the vehicle collision damping device of the present invention, a cushioning main body for deforming due to the collision of the vehicle to cushion the impact on the vehicle and stopping the vehicle, and a seat member stepped on by the vehicle at the time of the collision. Are separately molded, and the shock absorbing main body and the seat member are detachably connected when installed on the road surface to function as a vehicle collision shock absorbing device, and the one end of the seat member is branched. By sandwiching the buffer main body between the upper and lower sheets which are two layers of the double structure extending from the section, and by joining the upper and lower sheets by the joining means provided at the open end of the double structure in this state, The cushion body is connected to the sheet member.

Since the buffer main body and the seat member have a size and a length that can cope with a collision of various automobiles including a large-sized vehicle, the buffer main body and the seat member are light loads to be handled manually. is not. However, as described above, according to the vehicle collision damping device of the present invention, since the cushioning main body and the sheet member can be separately transported at the time of installation at a road construction site or the like, both members remain integrally connected. It is easier to handle than the ones and the burden on the operator is reduced.

After transportation, the sheet member is placed on the road surface, the upper sheet of the double structure portion at one end is opened to the lower side, the cushioning body is placed on the lower sheet, and the upper sheet is overlaid. The joining of the cushioning body and the sheet member can be completed by a simple procedure in which the cushioning body is sandwiched between the sheets and the upper and lower sheets are joined by the joining means of the open ends.

In the structure of the present invention, the vehicle collision damping device can be easily installed by the simple procedure as described above. Further, since the joining means is releasable, when the device is withdrawn, if the joining of the upper and lower sheets of the double structure part is released,
The cushioning body can be easily removed, and the cushioning body and the sheet member can be returned separately from each other and easily transported.

Further, since the shock absorbing main body is detachable from the seat member in this way, if deterioration or damage is found in either the shock absorbing main body or the seat member during long-term use, only one of them is replaced. All that is required is a long service life as a whole. In this way, it is not always necessary to replace the entire device anew, and partial replacement is possible, so the cost of the device can be reduced.

Further, the joining means of the present invention has a strong construction so that the joining portion is not released or broken due to the impact at the time of collision of the automobile and the shock absorbing body is not flipped off. Moreover, it is desirable that the work of joining and releasing is simple. For example, industrial fasteners and strong bonded surface fasteners are preferred, and other configurations such as snap fastening and button fastening can be used.

Further, the shock absorbing main body can be composed of various shock absorbing members capable of absorbing shock while deforming at the time of collision. For example, molded products of various synthetic resins such as polyurethane, polyethylene, polypropylene, rubber, etc. and foams are relatively lightweight and easy to handle compared to water drums and a large number of sand bags. Can be mentioned.

These cushioning members are not used individually but are covered with a wrapping member having high strength as is conventionally done to form a cushioning main body. It becomes large and is preferable. In this case, by forming an air vent hole in the packaging member, it is possible to prevent the shock absorbing main body from bursting at the time of a collision. The air vent hole is
It may be formed by eyelet processing or the like.

When the cushioning body is made of one solid cushioning member, one or more hollow portions may be formed in the cushioning member so that the cushioning member is easily deformed at the time of collision and the member itself is pulled. It is possible to avoid breaking and breaking, and improve the durability of the buffer body. The hollow portion may be formed in advance by a mold used for molding various synthetic resins as described above, or may be formed by cutting after molding. It is also possible to use a porous material.

Further, the sheet member in the present invention is desired to have high water resistance and strength capable of withstanding running and tension of an automobile, and for example, polyvinyl chloride is preferable.

In the double structure part of the present invention in which two sheets are stacked above and below one end of the sheet member, for example, the end of another sheet having a predetermined length is provided at the branching part of one end of one sheet member to be branched. It can be integrally formed by fusion or the like.

Further, it is preferable that the sheet member is provided with a weight so as not to be curled or twisted by wind pressure when installed on the road surface. For example, if at least one tare portion is provided so that the weight can be inserted and removed, the weight may be inserted into the tare portion when the apparatus is installed on a windy day. Also,
Since the weight can be pulled out from the tare portion when the device is withdrawn, it is easier to handle than the case where the sheet member itself is heavy, and the workability is good.

Such a tare portion can be formed by stacking another sheet material on the sheet member and adhering the edges thereof, or the sheet member itself can be formed by stacking two sheets. By partially adhering at predetermined intervals,
A tare portion can be formed between the adjacent adhesive portions.

In this case, if a certain adhesive portion of the two sheets is used as a branch portion and one end side is left open, a double structure portion in which two sheets are vertically stacked for connecting the buffer main body is simple. Therefore, a joining means for releasably joining the upper and lower sheets together at their open ends may be attached.

The shape of the buffer main body may be any one that can be stably placed on the road surface, and examples thereof include a sideways triangular prism shape and a square prism shape. In addition, the double structure part that is the cushioning body connecting part of the sheet member joins the upper and lower sheets at a length position along the outer shape of the cushioning body so that it can be firmly held from above and below along the outer surface of the cushioning body. As described above, it is preferable to set the length of the seat, the mounting position of the joining means, etc., and make the seat width substantially the same as the width of the buffer body.

The width of the seat member and the buffer body is
In order to properly receive the vehicle to be collided, it is desirable to have a width that spans the width of the vehicle, but if one set of seat member and cushion body have such a width, both members will become very large, and transportation, Not only is it difficult to install, but it is also not easy to manufacture and store, so two pairs of relatively small widths, for example, 1/2 to 2/3 of the vehicle width are installed side by side. It is desirable that the structure be used because it is simple.

In order to improve the visibility of the driver, it is possible to attach a sheet with a zebra mark or an arrow mark that calls attention to the surface of the sheet member in the surface area facing the entering vehicle on the upper side of the buffer body. To be Furthermore, by making the area of the sheet member a light reflecting surface, it is possible to improve visibility especially at night. This light-reflecting surface is composed of the sheet itself as a light-reflecting sheet, attached with a light-reflecting sheet, or coated with light-reflecting paint
Further, the mark sheet can be easily constructed by a method of forming the mark sheet with a light reflecting sheet.

If convex portions are provided at appropriate intervals in a region of the seat member in front of the cushioning body to form a continuous concave and convex state, the driver can easily notice when riding on the seat member and step on the brake. As the vehicle speed increases, the frictional resistance between the automobile and the seat member and the road surface increases, and the vehicle can be stopped earlier and more reliably. The tare portion in which the weight is stored as described above can also function as the convex portion due to the bulge.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As an embodiment of the present invention, FIGS. 1 to 4 show a vehicle collision shock absorbing device in which a shock absorbing main body has a sideways shape of a triangular prism. FIG. 1 is a schematic perspective view showing an overall configuration of the vehicle collision damping device, FIG. 2 is a perspective view of a joint portion of a cushioning main body, and FIG. 3 is a schematic diagram showing an example of the shape of a cushioning member of the cushioning main body. 4 is a schematic view showing an example of the configuration of the sheet member.

The vehicle collision damping device 1 according to the present embodiment is
Mainly, when the vehicle collides on the road surface, it is deformed to buffer the impact on the vehicle, and at the same time, the shock absorber body 2 has a triangular prism laying down shape for stopping the vehicle, and when the vehicle is expanded on the road surface, the buffer body 2 is spread. The seat member 3 is stepped on by the vehicle.

In the present device 1, the cushioning main body 2 is detachably coupled to one end portion of the sheet member 3 to be integrated. Therefore, in this combined state, when an automobile collides with the cushion main body 2, the automobile is still riding on the seat member and pressing it against the road surface, and the cushion main body coupled with the seat member is repelled by the collision of the automobile. Without being blown, it will be impacted and deformed on the spot,
Also, the car can be ridden and stopped.

The present apparatus 1 has a branch portion at one end of the sheet member 3, and has a double structure portion 4 extending from this branch portion and stacking two sheets up and down. Industrial fasteners 5 are attached to the upper and lower sheet portions (4a, 4b) of 4 as joining means releasably joined to the open end portions.

Further, in this embodiment, the inner and outer lengths of the upper and lower sheet portions (4a, 4b) of the two-ply stack are substantially equal to the outer peripheral length of the buffer main body 2 in the ring state joined to each other by the industrial fastener 5. The length and the installation position of the fastener 5 are set. Therefore, the upper sheet 4a of the double structure part 4 at one end is opened with respect to the lower sheet 4b (FIG. 1 (a)), the cushioning body 1 is placed on the lower sheet 4b, and the upper sheet 4a is overlapped. When the cushion main body 1 is sandwiched between the sheets and the ends of the upper and lower sheets (4a, 4b) are joined to each other by the industrial fastener 5, the cushion main body 1 is provided with the upper and lower sheets (4a, 4b) along the outer surface thereof. The sheet member 3 and the cushioning body 2 are sandwiched between and firmly held, and the coupling between the sheet member 3 and the buffer main body 2 is completed (FIG. 1B).

As described above, in the vehicle collision damping device 1 of this embodiment, the cushioning main body 2 and the seat member 3 can be carried separately, and the burden on the operator is small, and the seat member 3 is placed on the road surface. , A simple procedure in which the cushioning body 2 is placed on the lower sheet 4b at one end of the sheet, the upper sheet 4a is closed, and the industrial fastener 5 is closed with the upper sheet 4a sandwiched between the sheets to join the sheet ends together. Thus, the installation work of the apparatus is completed at the same time when the cushioning main body 2 and the sheet member 3 are connected, and the whole work process can be easily completed in a short time.

In this embodiment, the buffer body 2
Has improved the strength as compared with the buffer main body composed only of the buffer member by wrapping the buffer member composed of the synthetic resin in the packaging member. For example, as shown in FIG. 2, a 0.35 mm-thick tarpaulin sheet laminated with polyvinyl chloride and polyester is used as the packaging member 10, and a cushioning member made of chip urethane having a specific gravity of 0.05 is used to form a width of about 800 mm and a depth of about 800 mm. ， When the buffer body 2 is constructed by laying down a triangular prism with a height of about 900 mm, the body weight is about 1
It was 3.6 kg. The height (about 900 mm) and size of the cushioning main body 2 are not so large as to be difficult to handle, and are effective in viewability, cushioning, and vehicle stopping effect corresponding to a large vehicle as an impact cushioning object. It can be said that it is suitable for road construction sites.

On the other hand, the sheet member 3 made of polyvinyl chloride having a width of about 800 mm and a total length of about 4800 mm in the joined state of the buffer main body 2 and a thickness of 1.0 mm is made of polyvinyl chloride.
The weight became about 8.3 kg.

When the buffer body and the sheet member having the same size and weight as these are integrally formed in advance, the total weight is 20 kg or more, which is a heavy load for handling by hand, but in the present embodiment. According to the configuration, since the cushioning main body 2 and the sheet member 3 each have a weight of about 10 kg and can be separately transported and handled, it is obvious that the burden on the operator is reduced.

Further, in the present embodiment, the packaging member 10 of the cushioning main body 2 is provided with the air vent holes 11 on the exposed side surface other than the area sandwiched by the one end of the sheet member 3 by eyelet processing, whereby the automobile Burst at the time of collision is prevented, and the durability of the buffer main body 2 is improved.

Further, of the upper and lower seats (4a, 4b) of the double structure portion 4 at one end of the seat member 3, the upper seat 4b above the cushioning main body 2 has a surface facing the incoming vehicle. The bonded surface fastener 6 is adhered to the surface area to be bonded at several places, and a light reflection sheet or the like is detachably attached. As a result, the visibility of the driver can be improved especially at night.
Instead of this sheet, a sheet having a zebra mark or an arrow mark that improves visibility even in the daytime may be used.

The cushioning member 12 in the packaging member 10 is
As shown in FIG. 3, by forming the hollow portion 13 in a member made of one solid, it is possible to more easily deform and absorb shock, and to enhance the cushioning effect and to prevent breakage due to shock at the time of automobile collision. Contribute to improving the durability of the buffer body 2. For example, the cushioning member 12 shown in FIG.
In the case of having a sideways shape of a triangular prism having a width of 800 mm, a depth of 800 mm and a height of 900 mm, a tubular hollow portion 1 having a diameter of 240 mm and a diameter of 85 mm is provided substantially at the center of the member.
If two 3 are provided, the possibility of damaging the cushioning member 12 can be greatly reduced.

The cushioning member is not limited to polyurethane, but a wide variety of cushioning members such as polyethylene, polypropylene, rubber, and various synthetic resins and foams can be used as long as they can be molded into a predetermined shape. Can be used.

Further, in the sheet member 3, the double structure portion 4 at one end portion is formed by fusing the end portion of another sheet member having a predetermined length at a desired branch portion to one sheet member serving as a base portion. Can be easily formed by adhering integrally. Alternatively, the entire sheet member may be formed of a laminated body of two sheets. In this case, the upper and lower sheets can be bonded to each other at a predetermined length position from one end to form a branch portion, and at the same time, one end portion can be formed into a double structure portion 4 in which two sheets are vertically stacked.

Further, if the upper and lower sheets are partially adhered to each other at predetermined intervals over the laminated region other than the double structure part 4, the tare part can be formed between the adhering parts which are adjacent to each other. If the weights of the tare parts are removably accommodated in the tare parts, the seat members 3 can be rolled by wind pressure by inserting the weights into the tare parts on a windy day. You can maintain the original state of being spread on the road surface without twisting or breaking. Of course, this tare portion can also be formed by stacking different small sheets on one sheet and adhering the edges thereof.

In addition, as shown in the side view (a) of FIG. 4 and the plan view (b) viewed from above, convex portions 7 are provided at appropriate intervals in the front region of the cushioning body 2 of the sheet member 3. If the driver is provided to form a continuous uneven state, the driver can easily notice when riding on the seat member 3 and quickly step on the break, and the frictional resistance between the vehicle and the seat member 3 and the road surface increases, and the vehicle stops. It can be faster and more reliable. In addition,
In the state where the weight is stored in the tare portion as described above, the bulge thereof can function as the convex portion 7.

In the above embodiment, the case where the industrial fastener is used to join the upper and lower sheets to each other at the open end of the double structure portion 4 of the sheet member 3 has been described.
As the joining means in the present invention, it is needless to say that not only the industrial fastener but also various means can be used as long as the joining means can be releasably joined and has a strength that is hard to be damaged even by the impact of an automobile collision in the joined state. Yes.

It should be noted that the vehicle collision damping device 1 as shown in the above embodiment may be used by actually installing two sets in a pair on the road surface in pairs at the actual site.

[0050]
