Abstract

PURPOSE:To obtain a high-safety, low-cost car stop which hardly injure the person or break the vehicle at the collision of a person or a vehicle. CONSTITUTION:The car stop is provided with an elastic, columnar rubber chip molded piece 3 which is obtained by setting under pressure a mixture of rubber chips with a synthetic resin binder and a rigid core material 2 embedded in the rubber chip molded piece 3 from the intermediate part to the lower part except the upper part at approximately the center of the rubber chip molded piece 3. Since the car stop has an elasticity, even at the collision of a person or a vehicle, the car stop never injures the person or breaks the vehicle and but has a high safety. In addition, since the core material 2 made of a steel pipe is embedded in the rubber chip molded piece 3 from the intermediate part to the lower part except the upper part at approximately the center of the rubber chip molded piece 3, a bumper of a vehicle comes into contact with an elastic part in which the core material 2 is not embedded. Therefore, the shock can be reduced, and the car stop is hard to break.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a highly-safe car stop that is not injured or destroyed even when a person or a vehicle collides.

[0002]

2. Description of the Related Art Conventional materials for bollards are frequently made of concrete, iron or the like because they are installed outdoors, have excellent durability, and are relatively low in price.

[0003]

The conventional bollards made of concrete, iron or the like have a great shock when a person or a vehicle collides, and the person is injured or the vehicle is damaged or destroyed. There was a problem that restoration of the bollard was troublesome.

It is an object of the present invention to provide at a low cost a highly safe car stop that will not be injured or destroyed even if a person or a vehicle collides.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a columnar rubber tip molded article 3 having elasticity obtained by pressurizing and solidifying a mixture obtained by mixing a synthetic resin type binder into a rubber chip, and the rubber chip molded article 3 are omitted. A core material 2 having a rigidity that is embedded in a central position and from an intermediate portion to a lower portion except an upper portion, the core material 2 is made of a steel pipe, and one of the insert nuts 6 provided on the core material 2 is provided. End face is rubber chip molding 3
It is a car stop that is exposed on the side of the car.

[0006]

[Function] Even if a person or a vehicle collides, the car stop itself has elasticity so that it is not injured or destroyed and the safety is high. Further, since the core material 2 made of a steel pipe is embedded substantially at the center of the columnar rubber chip molded product 3 and from the middle part to the lower part except the upper part, the vehicle bumper is elastic without the core material 2. It will come in contact with the part that holds the bumps, soften the shock, and the car stop is not easily destroyed, and even if it cracks a little, it can be attached with an adhesive material and can be easily restored compared to concrete, iron, hard plastic, etc. be able to.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a car stop according to the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a car stop installed at a parking lot, a boundary between a sidewalk and a roadway, etc. This car stop 1 has a steel pipe as a core material 2 and an outer periphery thereof covered with a rubber chip molding 3 and has a maximum diameter. 20 to 30 cm cone 4
A ball 5 is placed on the upper part of the core, and insert nuts 6 welded to both sides of the core material 2 are embedded on both sides of the boundary between the weight 4 and the ball 5, and a heaton 7 or the like is attached to the wedge. 8 etc. can be connected.

More specifically, the rubber chip molding 3
Is a mixture of rubber chips mixed with a synthetic resin binder, which is pressed and solidified to form a columnar body having elasticity. Further, the core material 2 is made of a steel pipe having a rigidity which is embedded substantially at the center of the columnar rubber chip molded product 3 and from the middle part to the lower part except the upper part. One end surface of the insert nut 6 is exposed on both side surfaces of the boundary between the cone 4 and the sphere 5 of the rubber chip molding 3.

The molding sequence of the bollard 1 will be described with reference to FIG. (1) A rubber chip made of waste material such as a tire, a binder such as a urethane resin that absorbs moisture in the air to be cured, and a pigment for coloring are mixed at a predetermined ratio shown in Table 1, respectively. To make mixture 12. Table 1 Mixing ratio (weight) Mixing ratio (% by weight) Rubber chip 100 76 Urethane resin 28 21 Pigment 4 3 Total 132 100

(2) As shown in FIG. 2 (a), a mold 13 made of a perforated plate such as a punching plate or a wire mesh is prepared. The pores of the perforated plate are smaller than the rubber chips of the mixture 12 and have a size that allows moisture in the air to pass through. The mold frame 13 is a split mold that is vertically divided into two along the center line of the car stop 1, and the upper side of the car stop 1 is closed and the lower side is opened.

(3) The mold 13 is turned upside down as shown in FIG. 2 (b), and the core material 2 made of the steel pipe is fixed at a fixed position, as shown in FIG. 2 (c). Then, the mixture 12 is divided into several times and charged while being pressurized at 30 to 50 kg / cm ² .

(4) After the mixture is filled and left at room temperature to solidify the mixture 12 with the internal binder, the formwork 13 is broken to take out the car stopper 1, and finishing treatment such as deburring is applied to the mixture, as shown in FIG. Complete car stop 1.

In the above-described embodiment, if a slightly thick rubber sheet or resin mat is cut out in various shapes and attached to the mold 13, the surface of the molded product can be patterned. Further, the mold 13 need not be a punching plate or a wire mesh, and may be made of another material such as a wooden mold having no holes as long as the moisture necessary for curing the urethane resin can be secured. Further, as the binder, it is possible to use one other than one that is cured by the moisture in the air.

[0014]

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, even if a person or an object collides, the shock is smaller than that of concrete, and there is almost no injury, bruise, or damage to the object. Further, when the vehicle collides, the car stop itself has elasticity, and the core material 2 made of a steel pipe is provided at a substantially central position of the rubber chip molded article 3 of the columnar body and from the middle portion to the lower portion except the upper portion. This softens the shock of a collision and prevents the car stop from being destroyed.

Further, even if some cracks are formed in the rubber chip molded article 3, it can be pasted with an adhesive and can be easily restored as compared with concrete or hard plastic. Furthermore, unlike the rubber molding by vulcanization, it does not require an expensive mold and can be molded with a sheet metal or wooden mold that is easy to process.Even one item can be profitable, and it is easy to install. Have.
