SI'OJAS PI RA AL I

The present invention relates to a protective coil according to the preamble of claim 1.

The shield aspirator according to the invention is intended to protect various hoses and wires.

At present, a so-called plastic thread is used. The protective spirals. The current most commonly used protective aspirator is made of a wide plastic band with a thread. Threads do not overlap. The current shield aspirator is intended to prevent external rubbing of the aforementioned hoses and wires, e.g.

The downside of current shielding spirals is that they do not provide the protection required by law when hydraulic hoses are broken when a part of the machine or the hydraulic hoses in the machine are close to a person. If the hydraulic hose inside the protective spiral currently in use breaks, the so-called "spiral" can be reached. high-pressure oil jet per person between the threads, thus posing a serious risk to the person affected by the jet. In addition, oil can be released into the environment, causing • • J 1.! 25 crossfire discomfort. When pneumatic hoses burst, there is also the danger of a compressed air jet coming from inside the spiral *.

The above reasoning is described in the utility model Ft 4136, ....: 35, which discloses a protective coil having retaining clips that hold the threads of the protective coil together.

• · pfi> Lttjlisr * * 117609 'jumps out of the opposing retaining member, allowing the thread to open and it is problematic that the thread opens rapidly along the entire spiral path 5 because the retaining member slides along the surface of the thread. Once the protective spiral has opened, it has to be returned to its original closed position by hand, this is a slow job, especially if the protective spiral is very long or difficult to reach.

It is an object of the invention to provide a protective spiral which is not completely dismantled even if one or more threads or parts thereof are opened due to mechanical or other stress. Another object is that the manufacturing must be advantageous.

The foregoing disadvantages can be overcome and the above-described objects are achieved by a protective spiral according to the invention, which is characterized in what is defined in the characterizing parts of the claims.

One of the main advantages of the invention is that the invented protective spiral 20 is not completely dismantled even if one or more threads or parts thereof are opened due to mechanical or other stress. The non-discharge spiral structure makes the protective spiral very protective. A further advantage of the invented protective spiral is that the partially opened protective spiral can be quickly and easily returned to the closed state.

The invented retainer 2 consists of one or more recesses. The retainer 2 * 117609 4 consists of one or more recesses in the retaining member Ib, the body portion 1 having one or more retainers 2 for stopping the spiral discharge.

The invented retainer 2 has one or more retainers 2a, wherein the retainer 1 has a stopper abutment 2aaa that engages the shielding coil so that the coil is not disengaged.

In Figures 1, 2, 3, 4, 5 and 6, the retaining member 2 is the height of the retaining member Ib, as viewed in the ascending direction of the thread of the recess in the retaining member 2, acts as a retaining 2a whose retaining ability can be controlled by selecting a retaining angle 2aa. The retainer 2a is parallel to the diagonal of the spring through the center of the body portion 1, with the retaining angle 2aa being 0 degrees.

According to the invention, the retaining angle 2aa may also be larger, whereby the retaining 2a is preferably 25-45 degrees and preferably 25-0 degrees with respect to the diagonal passing through the center of the body part 1, resulting in an end away from the body part 1 of the retaining body 2a. arrestor 2aaa is so called. sharp, which results in a very good spiral protection.
