Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vehicle stop installed at an entrance of a park or a boundary portion between a sidewalk and a roadway.
[0002]
[Prior art]
Conventionally, as a car stopper installed at the entrance of a park or a boundary part between a sidewalk and a roadway, for example, a concrete pile or a metal pipe is typically planted on the ground. Since such a conventional car stopper is a rigid body, there is a problem that the vehicle body is recessed or the paint is peeled off even if the automobile is lightly touched. Further, when the automobile is strongly contacted or collided, there is a problem that the car stop itself is broken. Furthermore, under conditions of poor visibility, such as at night, there was a problem that passers-by would contact the car stop without being aware of the presence of the car stop, resulting in injury.
[0003]
For this reason, car stops using elastic materials such as rubber have been put to practical use as car stops that do not damage the vehicle body with light contact, are not easily broken even with strong contact, and are less likely to be injured when a passerby contacts them. Has been. Moreover, as shown in JP-A-8-232219, while using a metal or resin pipe, it is divided into a portion buried in the ground and a portion standing on the ground, and both are made of elastic members. Something to be linked has also been proposed.
[0004]
FIG. 7 shows a configuration of a conventional vehicle stop disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 8-232219. As shown in FIG. 7, this conventional car stopper is composed of a lower columnar body 1, most of which is buried in the ground, and an upper columnar body 2 connected to the upper portion of the lower columnar body 1. The lower end of 2 is pivotally supported by a spherical guide 3 provided at the upper end of the lower columnar body 1. The lower columnar main body 1 and the upper columnar main body 2 are connected by a shaft 4 having screws formed at both ends and nuts 5 and 6, and an elastic body 7 provided between the lower columnar main body 1 and the shaft 4, The backlash between the lower columnar main body 1 and the upper columnar main body 2 is absorbed, and the movement of the upper columnar main body 2 is restored by its elastic deformation. With such a configuration, even when the automobile 8 comes into contact with the upper columnar body 2, the upper columnar body 2 is tilted, and damage to the vehicle body such as a dent in the vehicle body of the automobile 8 or peeling of the paint can be prevented.
[0005]
[Problems to be solved by the invention]
However, according to the conventional vehicle stop shown in the above-mentioned JP-A-8-232219, a spherical guide 3, a shaft 4, nuts 5 and 6, an elastic body 7, etc. are connected to the connecting portion of the lower columnar body 1 and the upper columnar body 2. And the number of parts increases, and man-hours are required for assembling these parts such as welding, screwing and press-fitting, leading to an increase in cost. In particular, when installed on a sidewalk at regular intervals, a large amount of car stops are required, so the unit price of car stops is preferably as low as possible.
[0006]
On the other hand, it is impossible to completely prevent breakage of the car stop due to deterioration of the car stop itself due to repeated contact of the car or collision of the car. In this regard, if the car stopper itself is molded from an elastic body, the portion buried in the ground must be excavated and replaced with a new one, which requires man-hours for the replacement work and increases the work cost. Had the problem. In addition, in the conventional vehicle stop shown in the above-mentioned JP-A-8-232219, there may be a case where only the broken upper columnar body 2 can be replaced. 4 and the spherical guide 3 are likely to be deformed, and the lower columnar body 1 must also be dug out and replaced.
[0007]
The present invention has been made to solve the above-described problems of the conventional example, and when the automobile touches lightly or a passer-by contacts, the vehicle is appropriately deformed and the vehicle body is damaged or the passer-by is injured. An object of the present invention is to provide a vehicle stop that can be prevented and can be easily replaced when the vehicle stop itself is broken.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of a vehicle stopper according to the present invention will be described. FIG. 1 is a front view showing a configuration of a car stopper according to the present embodiment. 2 is a partial cross-sectional view showing the configuration of the columnar section 20 in FIG.
[0019]
As shown in FIG. 1, the vehicle stop of the present embodiment is composed of a base portion 10 and a columnar portion 20, and in the example shown in FIG. 1, a part of the base portion 10 is embedded in the ground. The base portion 10 is a cylindrical body made of metal such as steel, stainless steel, and aluminum subjected to rust prevention treatment such as painting or plating. An anchor 11 is provided in the vicinity of the lower end portion of the base portion 10 so as to be substantially orthogonal to the central axis of the base portion 10 and is prevented from coming off when buried in the ground. The height h of the base portion 10 protruding from the ground GL is a height that does not contact the bumper of the automobile.
[0020]
As shown in FIG. 2, the columnar portion 20 is a rod-shaped body integrally formed of a highly elastic resin material such as rubber or plastic, and a portion parallel to the central axis of the columnar portion 20 is formed inside the columnar portion 20. A core body 21 is provided. The core 21 is, for example, a metal wire (wire) such as spring stainless steel, a rod, a pipe, etc., and may be bent into a substantially U shape as shown in FIG. It may be used. Or what wound the wire spirally may be used. By providing such a core body 21, even if the columnar part 20 is broken, it is possible to prevent the broken part from being scattered and scattered.
[0021]
The lower end 22 of the columnar part 20 is a part fitted into the upper end opening of the base part 10, and the outer diameter thereof is set to be slightly smaller than the inner diameter of the upper end part of the base part 10. In the case of this example, the maximum outer diameter of the columnar part 20 and the outer diameter of the base part 10 are designed to be substantially equal, but the present invention is not limited to this. In addition, as shown in FIG. 1, in a state where the columnar portion 20 is fitted to the base portion 10, both are fixed with screws or pins 12 to prevent the columnar portion 20 from being inadvertently detached.
[0022]
An annular groove 23 is formed in the vicinity of the lower end of the columnar portion 20 and on the outer periphery of the portion below the position where the bumper of the automobile contacts with the columnar portion 20 fitted to the base portion 10. . The number of the annular grooves 23 is not particularly limited. The groove 23 is provided to concentrate the stress when the vehicle or a passerby comes into contact with the vehicle so as to be easily deformed. Further, when the car stopper breaks, the groove 23 is provided to be broken from the groove 23 exclusively. It has been. Accordingly, the cross-sectional shape of the groove 23 is not particularly limited as long as it is a shape that causes stress concentration when an automobile or the like comes into contact.
[0023]
Furthermore, an annular groove 24 is also formed near the upper end of the columnar portion 20. The upper groove 24 is used to make it easier to recognize the presence of the car stop by painting this part in a different color from the other parts or applying a reflective tape to this part. Therefore, the upper groove 24 is not necessarily provided. The lower groove 23 may also be painted or reflective tape.
[0024]
In addition to unused new rubber and plastic, the above-mentioned resin materials include recycled materials such as recycled used plastics and crushed used rubber products into chips and hardened with resin. It may be used.
[0025]
Next, a first modification of the present embodiment is shown in FIG. The vehicle stop according to the first modification is different in the internal configuration of the columnar portion 20 and is otherwise the same as the above case.
[0026]
As shown in FIG. 3, the columnar portion 20 is a rod-shaped body that is integrally formed of a highly elastic resin material such as rubber or plastic as described above. A parallel pipe-shaped core body 21 '(single unit) is provided. In consideration of the dent at the time of resin molding, at least the upper end portion of the core body 21 ′ is closed. By making the core body 21 'into a pipe shape in this way, the configuration of the columnar portion 20 is simplified and molding is facilitated.
[0027]
Furthermore, as an example, the diameter of the core body 21 ′ is set to about ３ of the diameter of the columnar portion 20. Specifically, when the diameter of the columnar portion 20 is 100 mm, the diameter of the core body 21 ′ is 30 to 40 mm. In this way, by making the thickness of the resin material portion of the columnar portion 20 approximately the same as the diameter of the core body 21 ′, the automobile is in light contact with the core body 21 ′ while maintaining a certain degree of strength. Even in this case, deformation of the resin material portion of the columnar portion 20 can prevent or reduce peeling of the dents and paint of the vehicle body.
[0028]
In general, since the diameter of the car stopper is limited to some extent (about 100 mm), if the diameter of the core body 21 'is made larger than about 1/3 of the diameter of the columnar portion 20 (for example, 1/2), The thickness of the resin material portion is reduced, and the effect of preventing or reducing the peeling of the dents and paint on the vehicle body is reduced. Conversely, if the diameter of the core body 21 ′ is made too smaller than about 1/3 of the diameter of the columnar section 20 (for example, 1/5), the strength of the core body 21 ′ is insufficient and even if the automobile is lightly touched. The core body 21 ′ is deformed. Therefore, the ratio of the diameter of the core body 21 ′ to the diameter of the columnar portion 20 is preferably in the range of 1 / 2.5 to 1/4.
[0029]
Next, a second modification of the present embodiment is shown in FIG. In the second modification, the columnar portion 20 is constituted by a lower end member 25, a cylindrical member 26, and an upper end member 27, and is substantially a hollow body. The lower end member 25 and the upper end member 27 are formed using the resin material, and the cylindrical member 26 is formed using a metal pipe such as steel, stainless steel, or aluminum subjected to rust prevention treatment, a resin pipe, or the like. Thus, according to the 2nd modification, the columnar part 20 can be made hollow and the weight of the columnar part 20 can be reduced. Moreover, when the columnar part 20 breaks, it is thought that many of them have damaged only the lower end member 25. Therefore, in that case, it is only necessary to replace the lower end member 25, and the part cost can be reduced. The fixing method of the cylindrical member 26, the lower end member 25, and the upper end member 27 is not specifically limited, such as screwing, adhesion, press fitting, and insert molding.
[0030]
Furthermore, the 3rd modification of this embodiment is shown in FIG. In the third modification, the height of the cylindrical portion of the base portion 10 is set to a height h exposed to the ground, and a flange 13 is provided at the bottom thereof. Then, the flange 13 is fixed to the floor surface GL with an anchor bolt 14 or the like. Thus, according to the third modification, it is possible to install the vehicle stop of the present invention even in a place where the base 10 cannot be buried by digging the floor surface, such as a parking lot in a building. .
[0031]
Furthermore, the 4th modification of this embodiment is shown in FIG. 6A is a front view, and FIG. 6B is a side view. In this fourth modification, the installation direction of the car stopper is limited, and the reflecting plate 28 is provided in the vicinity of the upper end portion and the lower end portion of the columnar portion 20. That is, when the direction in which the reflector 28 is attached is the roadway side or the parking lot side, and the traveling direction of the automobile is determined, it faces the traveling direction of the automobile so as to easily reflect the light of the headlight. Thus, the direction of the reflecting plate 28 is determined. In this case, since the direction in which the automobile contacts, in other words, the direction in which the columnar portion 20 breaks is limited to some extent, the groove 23 does not necessarily have to be formed in an annular shape, and the groove where the reflector 28 is fixed is omitted. May be. Further, as a method for attaching the reflector 28, it may be adhered using an adhesive, but it is difficult to adhere to a resin material having relatively high elasticity such as rubber. Therefore, when the resin portion of the columnar portion 20 is molded, a metal member provided with a female screw or the like may be inserted in advance into the portion to which the reflecting plate 28 is fixed, and the reflecting plate 28 may be screwed. .
[0032]
As described above, according to the fourth modification, the reflector 28 reflects the light of the headlight of the automobile under a relatively dark condition such as at night or in an indoor parking lot. The driver can easily recognize the boundary between the sidewalk and the roadway or the parking lot, and it is possible to prevent an accident in which the automobile accidentally contacts the car stop.
[0033]
Furthermore, as another modified example, the columnar part 20 of the second modified example or the fourth modified example and the base part 10 of the third modified example may be used in combination.
[0034]
【The invention's effect】
As described above, according to the vehicle stop of the present invention, it is possible to attach to and detach from the base portion that is planted on the ground or floor and has a protruding height that does not contact at least the bumper of the automobile, and the upper end of the base portion. Since at least the vicinity of the lower end of the columnar part fitted to the base part is formed of an elastically deformable resin material, an automobile or a passerby can be used as the columnar part. When contacting, the vicinity of the lower end of the columnar part is elastically deformed, and the columnar part is inclined. Therefore, passers-by will not be injured, and damage such as dents and paint peeling will not occur depending on the degree of contact with the automobile.
[0035]
In addition, even if the car makes strong contact with or collides with the car stop, the protruding height of the base is lower than the bumper position, so it is unlikely that the car will directly hit the base, and the columnar part will be damaged or broken exclusively. It will be. At that time, since the base portion is hardly damaged, only the columnar portion needs to be replaced, and the component cost can be reduced. In addition, since it is not necessary to dig up the base, it is possible to reduce the work cost required for replacing the car stopper.
[0036]
Furthermore, with regard to the car stopper itself, only the lower end of the columnar part is fitted to the upper end of the base part, the structure of the connecting part of the base part and the columnar part is simple, and the number of parts is small. Can be lowered.
[0037]
Moreover, by making the whole columnar part into a rod-shaped body made of the resin material, the shape of the columnar part becomes simple, the number of parts is small, and the manufacture becomes easy.
[0038]
Further, even if the columnar part is broken by providing a core body formed of a material different from the resin material and having at least a portion parallel to the central axis of the columnar part inside the rod-shaped body. It is possible to prevent the columnar parts from falling apart and the scattered debris from being scattered.
[0039]
Alternatively, although the columnar part is a cylindrical body in which the upper end member and the lower end member formed in the predetermined shape are fixed to the both end openings of the cylindrical member respectively, the number of parts increases, but the columnar part Can reduce the weight.
[0040]
Furthermore, by forming at least one substantially annular groove on the outer peripheral surface in the vicinity of the lower end of the columnar part, stress when an automobile or the like comes into contact with the substantially annular groove part is concentrated. Deformation can be absorbed. Moreover, also when a columnar part breaks, possibility that it will break from this substantially annular part becomes high. As a result, the columnar portion can be easily deformed, and damage to other portions of the columnar portion can be reduced. In particular, when the columnar part is the cylindrical body, it is only necessary to replace the lower end member, and the part cost can be further reduced.
[0041]
Further, by using the resin material as a recycled material, it is possible to effectively use resources and reduce the material cost in the cost of stopping the vehicle.
[0042]
Furthermore, by using a metal wire, rod, or pipe as the core, known materials and manufacturing methods can be used, which facilitates the manufacture of the columnar portion of the rod-like body and reduces its manufacturing cost. be able to.
[0043]
Alternatively, the core body is pipe-shaped, by a range of 1 / 2.5 to 1/4 with respect to the diameter of the core body diameter of the columnar portion, the configuration of the columnar portion can be simplified, Molding becomes easy, and even when the automobile is lightly touched while maintaining the strength as a car stopper, it is possible to prevent or reduce the dent of the vehicle body and peeling of the paint.
[0044]
Further, by embedding a part of the base portion in the ground, it is possible to install a car stopper in a narrow place such as a boundary portion between a sidewalk and a roadway.
[0045]
Alternatively, by providing a flange parallel to the ground surface or floor surface at the base, and fixing it to the ground surface or floor surface, the vehicle can be stopped even in places where the ground or floor surface cannot be dug deeply, such as a parking lot of a building. Can be installed.
