Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a guard pipe that constitutes a shelf for a car stop.

"Problems that conventional technology and ideas are trying to solve" Guard pipes (poles) that make up the shelf of a car stop
A number of guard pipes are erected on the ground at appropriate intervals, and chains and ropes are strung between them, but cars often collide with these guard pipes, which can cause damage to not only the guard pipes but also the cars. There are so many.

Therefore, the present invention aims to reduce such damage by causing damage to both bodies by elastically deforming them during a collision, and by preventing new problems caused by the elastic deformation, namely, excessive thrusting. The aim is to eliminate the unreasonable deformation caused by this, as well as the damage that accompanies this.

"Means for solving the problem" The present invention divides the guard pipe main body 1 into upper and lower halves at the lower or middle part, and interposes a shock absorbing material such as a spring 12 and a rubber mass in this part. 1 is equipped with a collision notification device A that operates depending on the inclination of the part.

``Function'' Because of the above structure, when a car collides, the spring 12, the cushioning material such as the rubber block, etc. will soften the impact, and will also appropriately deform elastically to respond to the pressure. , eliminate damage along with the vehicle that collided with it.

When the guard pipe main body 1 is tilted due to a collision of a car, the collision notification device A is immediately activated to notify the driver etc. of the collision.

"Example" The illustrated embodiment will be described below.

In the figure, 1 is the guard pipe body, 2 is
3 is a locking mechanism that locks and holds the guard pipe body pulled out to the ground; A is a collision alarm installed on the top of the guard pipe body; It is a device.

Guard pipe body 1 is divided into two parts at the bottom, top and bottom.
At this portion, the sleeves 11a and 11b are fitted inside and their end surfaces abut each other, and a spring 12 serving as a buffer material is fitted between the sleeves.

Note that the two-way point may be in the middle. The cushioning material is
A rubber block or the like may also be used. The sleeve may optionally be omitted.

The collision alarm device A is an internally powered electrical device, and is equipped with a tilt detector 4 consisting of a pendulum type switch and a battery case 1 inside the upper part of the guard pipe main body 1.
5, and a battery 16 that can be detachably attached to the battery case.
Furthermore, an alarm buzzer 17 and an indicator lamp 18 are provided at the upper end of the guard pipe main body 1, and the alarm buzzer and indicator lamp are electrically connected to the battery 16 via the tilt detector 14. , a translucent cover 19 is attached to the upper end of the guard pipe body 1,
The warning buzzer and indicator lamp are covered watertight.

It should be noted that the collision notification device may be formed into a suitably shaped unit and attached to the upper end of the guard pipe main body. Further, an external power source may be used, or a power switch may be interposed in the circuit.

With the above configuration, when a car collides, the spring 12 is elastically deformed and the upper part of the guard pipe main body 1 falls down, so that it is not damaged together with the collided car, and in this case, In the notification device A, the tilt detector 14 is turned on, the alarm buzzer 17 sounds, and at the same time the indicator lamp 18 lights up to immediately notify the driver etc. of the collision.

``Effects of the invention'' According to the invention, even if a car collides, the shock is softened by the cushioning material, and the pressing force at that time is absorbed by the elastic deformation of the cushioning material, causing damage to both the guard pipe and the car. The collision notification device A operates at the same time as the collision, and the driver etc. is immediately notified of the collision. Therefore, it is possible to eliminate excessive thrusting and the unreasonable deformation caused by it. Damage can also be eliminated, and new problems caused by elastic deformation of the cushioning material can be eliminated.

It is simple in structure and manufacture, and can be provided at low cost, which is extremely useful in practice.
