[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a hand truck and a passage through which a plurality of such trucks are connected and run by a tow vehicle, especially near a stop position, a turning position, etc. of the car. When you install it and stop the movement of the car, change the direction, etc.,
The present invention relates to a car stop pole used for preventing a pillar, a wall, and other objects from being damaged by a collision of the car.

2. Description of the Related Art Conventionally , a synthetic rubber buffer band 12 is attached to a predetermined position of a metal pole body 11 as shown in FIG. 2 , or Japanese Utility Model Laid-Open No. 62-177853.
The one disclosed in Japanese Utility Model Publication No. 64-14216 is
is there. Then, it, for example, it is known that so as to prevent damage to the pillars mounted on the floor A of the corner pillar B positions redirecting as FIG.

[0003]

In the conventional bollard pole as shown in FIG . 2 , since the pole body is a rigid body made of metal, the impact force applied to the pole body is It acts on the floor surface straight to the extent that it is slightly weakened by the buffer strip attached to the. Therefore, due to the vibration caused by the impact, the concrete floor surface to which the pole is fixed is likely to be cracked or damaged, and if the floor surface is damaged, the effect as a single stop cannot be fully expected and the floor surface cannot be expected. There was a problem such as inconvenience such as not being used as a single stop at the time of repairing the damage. In addition, actual development Sho 62-17785
The one disclosed in Japanese Patent No. 3 uses a tension spring 5 to fix the collapsible tube 2
The effect of restoring the tilt can be expected, but it is added to the tiltable tube 2.
The effect of alleviating and absorbing the impact that is generated cannot be expected at all. Furthermore,
The one disclosed in Japanese Utility Model Publication No. 64-14216 is installed on the installation section G.
Use the inner layer metal tube 2 to remove the non-flexible hollow part NB (HA)
The outer circumference of the metal tube 2 is formed, and a hollow exterior part of elastomer is formed.
Since it is surrounded by 1, the inner metal tube 2 is a rigid body
However, there is a problem that it lacks shock absorption.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems of the conventional products, the present invention provides a space between a lower cylinder protruding above a bottom plate fixed to the floor and a cylinder above it. Are connected by a coil spring, and the outer peripheral surface of the coil spring and the outer peripheral surfaces of the upper and lower cylindrical bodies are hard-synthesized so that a vertical hole having a diameter substantially equal to or smaller than the inner diameter of the coil spring exists in the center of the coil spring. The cushioning pole body was formed by enclosing it in a tubular shape with a cushion body having an appropriate elasticity such as rubber.

[0005] Then, to reinforce the strength and durability against <br/> impact fitted core body having suitable elasticity made of hard quality synthetic rubber in the longitudinal hole of the buffer pole body.

[0006]

Since [action] buffer pole body of the present invention is embedded coil spring the lower portion, the shock against buffer pole body in the longitudinal hole of the buffer pole body with mitigated by the elasticity of the elastic coil spring having the cushion body
Since the core body is inserted and inserted, the core body has an effect of reinforcing bending strength and durability against impact and absorbs the impact by the core body to reduce vibration to the floor surface.

[0007]

1 is a front sectional view of an embodiment of the present invention, in which a lower cylindrical body 2 protruding from a bottom plate 1 fixed to a floor surface A of concrete or the like and the cylindrical body 2 are provided. A coil spring 4 is connected to the upper cylindrical body 3.

A vertical hole 5 having substantially the same diameter as the inner diameter of the coil spring 4 is provided at the center of the coil spring 4 so that the outer peripheral surface of the coil spring 4 and the outer peripheral surfaces of the cylindrical bodies 2 and 3 are appropriately formed. The cushioning pole body 7 was formed by enclosing it in a tubular shape with the cushion body 6 made of hard synthetic rubber having elasticity.

Reference numeral 8 denotes a core body made of a hard synthetic rubber which is fitted in the vertical hole 5, and the core body 8 made of a hard synthetic rubber having appropriate elasticity has a bending strength and an impact of the buffer pole body 7. It is used for improving the force absorbing effect, and when the core body 8 is inserted into the vertical hole 5, the strength against the shock applied to the buffer pole body 7 becomes large, and the durability is excellent.
Shock absorption is also performed by the core.

In the figure, reference numeral 9 is a rubber cap which is placed on the upper end of the buffer pole body 7, and 10 is a cover body which is placed on the lower end of the buffer pole body 7 so as to cover the bottom plate 1.

[0011]

In the buffer pole body of the present invention, the lower cylinder and the upper cylinder are connected by a coil spring, and the outer cylinders of the upper and lower cylinders and the coil spring have a proper elasticity. Since it is surrounded by the body in a cylindrical shape, the elasticity of the cushion body and the elasticity of the coil spring absorbs and absorbs the impact compared to the conventional metal pole, so that the transmission of vibration to the floor surface is reduced. It

Further, a core is fitted in the vertical hole of the buffer pole body.
Since it is inserted, the bending strength against the shock applied to the buffer pole body is reinforced, and the deterioration of elasticity due to metal fatigue of the coil spring is compensated for, so the durability is further increased and the shock is also affected by the core body. Absorbs to reduce vibrations to the floor surface and has excellent durability.
