Description

Detailed Description of the Invention <Industrial Application Field> The present invention comprises a base body made of a rigid-elastic synthetic resin that can be fixed on a support plate, and a flexible band or Pipe fittings with a U-shaped retaining part integrally connected to the base body via a web are related to the fastening device, especially when vibrations occur in the pipe opening body, such as in the brake piping of anti-chain braking systems. In such cases, a tube attachment that can be held in such a way as to dampen vibrations of the tube is associated with a fixation device.

<Conventional technology> Conventionally, pipe attachment to hold the pipe was performed using a fixing device.
The one described in Publication No. 83464 (Utility Model Application No. 48-138911 (Utility Model Publication No. 49501-1983)) is well known.

This pipe mounting fixing device has a base body with two walls,
The holding part is firmly sandwiched between these wall parts, and the holding part is held on the base body by the engagement of the protrusion between the wall part and the holding part.

The flexible band that integrally connects the base body and the holding part has the following purpose. That is, the holding part is held open in one direction so that the tube can be accommodated above the wall part.

Then, when inserting the tube, the ends of the holding parts are guided together and pressed down between the walls until the projection of the holding part settles below the corresponding projection of the wall. . This tube attachment fixing device can easily hold the tube and can reliably hold the pinched tube without being separated by the vibrations of the vehicle.

<Problems to be Solved by the Invention> However, when holding brake piping, especially brake piping in a non-chain type brake system, vibration occurs in the pipe, and this vibration cannot be caused by conventional pipe installation. If a fixing device is used to hold the tube stationary, the vibrations will be transmitted to the vehicle body and cause significant vibrations in the vehicle body due to the body's natural frequency.

The object of the invention is to provide a fixing device for pipe attachment ξ which makes it possible to capture or dampen vibrations in the brake pipe of an ABS system (anti-brake system).

Means for Solving the Problems According to the present invention, the above object is achieved as follows. The holding part is thus held in the basic body by means of a spring-like web. The outer wall and projections of the holding portion are spaced from the inner wall and projections or cutouts of the base body by a sufficient distance to eliminate vibrations in all directions. As a result, the holding part is held by the bearing surface of the projection or cutout after the web has been elastically bent short in the event of an unexpected external force. The spacing between the projection or cutout and the support surface must be chosen such that the legs of the spring-like web are not stressed beyond their elastic bending range when subjected to the above-mentioned forces. When sizing the spring-like web, which must not be Care should be taken to ensure that the material has sufficient elasticity. The last mentioned requirement can be very well met when the spring-like web is formed from two webs, each straight and connected to each other at an acute angle, as described in another form of the invention. can.

Embodiments The pipe attachment and fixing devices shown in FIGS. 1 to 3 are based on the technical aspects of the invention for securing pipes, particularly brake pipes.

This pipe attachment fixing device consists of a base body 1 made of synthetic resin with side valve properties, and a U-shaped holding part 2 surrounding the pipe 3 on both sides. This base body 1, which is integrally connected to the base body 1 by a flexible web 4, has a bottom plate 6 which can be fixed on a support plate 5 and two U-shaped connections to this. It is formed from a wall 7, at the end of which a hook-shaped projection 8 projects inwardly. This base plate 6 can be connected to the support plate 5 by any fastening method, such as screwing, riveting, gluing or other methods.

The holding part 2 is made in a U-shape and has an opening 1 on its upper side.
1 is covered by a supporting finger part 9 which can be deformed like an elastic spring. This finger part 9 is formed at an extension 10 of the holding part 2 at a distance above the opening 11 .

When pushing the tube 3 into the opening 11, the supporting finger parts 9 are forced laterally apart (see FIG. 2).

Then, it springs back elastically to its original position and the tube 3 settles in the holding part 2 (see FIG. 3).

The outer wall 12 of the holding part 2 fits into the contour of the inner wall 13 of the base body 1 and has the same spacing "a=1" in all respects to this inner wall 13. The holding part 2 furthermore has a lateral It comprises two projections 14 which are provided with a gap "S" corresponding to the spacing "a" with respect to the opposite hook-shaped projection 8. The flexible web 4 is elongated. It surrounds the hook-shaped protrusion 8 from the upper end of the section 10 in an arc shape and is connected to the outer wall 15 of the wall section 7.

The cross-sectional dimensions of the web 4 are determined as follows. l! II. When the tube 3 is inserted, the web 4 is attached to the holding part 2.
is held "floating" in its use position at a distance "a" from the inner wall 13. In addition, the web 4 is made flexible so that the holding part 2 can freely oscillate in all directions within the distance "a". Therefore, tube 3
If an unexpected external force is applied to the tube 3 after the tube 3 is held in the holding part 2, the holding part 2 becomes a spring-like web due to the cooperation of the hook-shaped projection 8 and the projection 14. After the tube 4 has been bent briefly and elastically, it will be held in its original position again, making it possible to capture or dampen the vibrations of the tube 3.

As is clear from FIG. 2, the spring-like web 4 is bent so as to spread laterally when the tube 3 is inserted.
The outer wall 12 of the holding part 2 is supported on the inner wall 13 of the base body 1. Therefore, the spacing "a" between the two walls 12 and 13 ensures that the spring-like web 4 is not stressed beyond its elastic bending range. Another embodiment is shown having a wall 7 which is shaped like this. In this embodiment, the spring-like webs are each formed from two straight webs 17, 18 connected to each other at an acute angle, and the retaining part 2
The web 17 connected to the tube 3 at the same time forms the introduction wall for the tube 3. In this embodiment, the spacing "'a" between the basic body 1 and the holding part 2 allows the spring-like web 1
7 and 18 can be prevented from receiving excessive stress.

FIG. 5 shows another embodiment of the invention with two retainers, this embodiment having a base body 1 for receiving a threaded bolt 21 mounted on a support plate 5;
This basic body 1 has a receiving part 16 which is determined by the dimensions of the bolt. The spring-like webs 17 and 18 formed at the receiving part 16 are bent and connected, as shown in FIG. This spring-like web 17 simultaneously serves as an introduction wall above the opening 11. - the force-bearing finger part 9 forms another introduction wall; A T-shaped protrusion 19 is formed at the lower arc of the holding part 2. This protrusion 19 is fitted into a T-shaped cutout 20 of the base body 1 with a spacing "a" therebetween.

The tube attachment shown in FIGS. 4 and 5 is constructed of two webs 17 and 18, each of which is straight and connected to each other at an acute angle. It has sufficient elasticity to

<Operations and Effects of the Invention> In the pipe fixing device according to the present invention, the outer wall and protruding portion of the holding portion held in the base body via a flexible band or web are connected to the inner wall and protruding portion of the base body. or have sufficient spacing to eliminate vibration in all directions relative to the hollowed out portion.

Therefore, when the holding part is subjected to an unexpected external force, the web is elastically bent short and then held on the support surface of the protrusion or hollowed out part of the base body, and the holding part is held Even if the tube held in the section vibrates, it is possible to capture or weaken the vibration of the tube.
