KR20010008383A - Piston for preventing hit-and-run car - Google Patents

Abstract

PURPOSE: A piston for preventing a hit-and-run car provides to prevent a pedestrian from a hit-and-run car. CONSTITUTION: A piston for preventing a hit-and-run car comprises of a first piston arm(1), a second piston arm(2), a piston head(4), a spring(6), a vibration absorbing part(7), a lid(8), and oil supplying hole(9). The first and second arms(1,2) are connected each other with a screw therefore the gap between a bumper of a vehicle and the piston is adjusted. The spring(6) keeps the certain distance of piston head and the piston arms(1,2). Different oil for each kind of a car is filled in a cylinder. Information about a car owner and a car is engraved on the lid. Therefore, the oil is flown out and the lid is separated when a car accident happens, and a hit-and-run car is traced with the oil and lid.

Description

Escape piston.

By attaching simple parts, it is possible to protect the pedestrian and change the driver's consciousness.

It is easy to manufacture because of simple operation, but the complete sealing of the contents of the piston in the cylinder comes first.

The external pressure generated by the collision pushes the piston back, leaving behind traces of breakage of the intrinsic liquid and aluminum plug in the cylinder.

〈Description of Main Parts of Drawings〉

[1] The material is a support for fixing bumper parts of P.V.C or aluminum vehicles. A male screw is provided inside to close the gap between the bumper and the frame according to the vehicle type.

[2] It is connected by bumper support [1] and female thread and can adjust tension [standard spacing] of tension of spring [3] by simple operation after attachment.

[6] In case of slight contact, the tension of the piston keeps the piston closed at intervals that do not force the piston.

[4] Rubber material keeps perfect sealing and pushes oil or silicon in cylinder [5] upon impact.

[5] Different types of silicone [soft] hump oil are used to leave the trace on the outflow surface at exit [8].

[3] Piston seals that act directly in the event of a vehicle crash are located and supported by tension-bearing springs and rubber barking that can withstand moderate flow.

[7] The small flow that can occur according to the surface condition of the vehicle while driving is properly prevented from changing the position of the absorbing piston sealer.

[8] Dark aluminum is used as the outlet of the contents embedded in the collision [5]. On the surface, it is possible to expect the triple effect by inserting the information of the owner, the shipment number, and the vehicle identification code at the time of shipment. have.

[9] After assembling all the parts, it is an inlet for oil and silicone to be in close contact with the front frame of the vehicle to prevent the loss of contents in the cylinder.

The operating principle of the specification is the description.
