Abstract

The pipe clamp exhibits two clamp halves (1, 2), whose first ends are connected to one another in an articulated manner and whose other ends can be locked to one another. For locking, one end of a first clamp half (1) exhibits a moulding (7) with stops, it being possible for the moulding (7) to latch in the flange (8) of a second clamp half (2) such that a plate (9), which can pivot away counter to the force of a spring member (10), interacts with the stops of the moulding (7). Consequently, a screw-free locking means for the two clamp halves (1, 2) can be formed, said locking means providing considerable advantages in terms of both costs and handling. <IMAGE>

Pipe clamp - Ett rörfäste

The invention relates to a tube clamp having two bracket halves, one end of which is pivotally connected and the other ends of which can be locked together, wherein the locking end of the first half of the bracket has a continuous a flange extending in the direction of the flange and having a through opening for the first half of the bracket mold, wherein the flap, which is pivotable against spring force and cooperates with the strip responses 10, partially obstructs the through opening on the flange side away from the first half of the bracket.

In most cases, the pipe clamp is installed first, and the final pipe clamping is then done by closing the previously clamped pipe clamps as a second step. Because the pipes to be installed are usually bulky and partly heavy objects, pipe fasteners are required to be sealed as simply as possible using only one hand.

35: From DE-PS 32 35 329, a cable clamp is known in the region of hose clips, the ends of which can be joined together without a screw plug.

At the end of the other half is a list with external teeth. In the second half, there are complicated knees to form a molding through hole. Because it is a cable clamp made of a relatively easy to deform material, complex knees are required to provide a sufficient 5 rigid flange. However, the easy deformability of the material also allows the free end to be used as a cover for the passage opening to prevent the release of the molded half. However, with this relatively simple possibility of creating a cover for the passage through a very easily deformable strip, the great disadvantage is that the forces exerted by the loads 10 are only allowed to move very little.

The said screwless closure, known from the area of hose clamps, cannot be used in pipe clamps. Because of the very different force conditions prevailing in the pipe clamps due to the high loads, other ma-15 materials are used which do not deform as easily as this type of ribbon material.

It is an object of the invention to provide a high-load-bearing tube bracket whose fastening halves can be joined together in a simple and easy manner as well as very quickly.

The problem is solved by the invention such that the cover strip cooperating with the stops of the strip is itself made of a rigid plate connected to the flange by a joint, and that the plate and the flange are supported by a spring member * * · '·' / 25.

• · · ···· ·· · V The plate covers the through hole so that the free portion corresponds to the • • · · V: axial projection, without stops. As the strip is passed through the plate-covered through outlet, the plate is pivoted to increase the free portion of the aperture by an axial projection of • V *: 30. Upon reaching the passage through the opening, the plate turns back to the corresponding stop holding the [·. support so that only the aperture area • · · 'corresponding to the axial projection of the unobstructed strip is uncovered. Responses that interact with the disc prevent the list from going back.

O 35 • V The pipe closure closure of the invention described above allows for a very simple, easy installation of the pipe. The pipes are inserted therein into a pre-installed ϊ 104386 3 bracket and the flexible halves of the bracket are closed by bringing the free ends together. The joining of the free ends causes the strip provided with a stop on one side of the bracket to pass through a through hole in the flange of the other half so that, with the nive-5, the flange associated plate engages its corresponding stop in the end position of the strip. This has the advantage that the tube clamp can be closed without the use of a difficult-to-handle screw. If it is not enough for the plate to engage the stop to secure the pipe to be installed, it is possible to connect the halves of the bracket with a screw known per se. Tightening the screw can then permanently secure the pipes inside the pipe bracket.

Thus, the above solution not only brings substantial advantages not only in terms of ease of installation and reduction of the hassle involved, but also goes a long way in economizing. This is achieved in particular because it is possible to dispense with the locking screw and not need more than one screw to provide, in a manner known per se, a flexible connection between the halves of the fastener.

A particularly advantageous fabrication structure between the flange and the plate 20 is obtained when the pivot axis of the joint is parallel to the center axis of the pipe bracket. The joint may then simply consist of a sticking tongue, ·. the second part of the recess. This gives you the opportunity to place the tongue in the • plate and • f 4 in the flange.

A preferred embodiment for forming the stops consists of having tooth-shaped projections in the mold, whereby the stop surfaces are located in these tooth-shaped projections. From a manufacturing point of view, it is advantageous to form the dental projections open to the outside of the bracket. The manufacture of Ham-5 bulky projections may be accomplished by designing the sides of the moldings, or the mold plane may be directly provided with such projections. The shape and number of protrusions can be varied, so that relatively few robust protrusions are load-bearing inexpensive but offer less locking capability. The finer design of the projections 10, on the other hand, offers greater locking possibilities but, for reasons of load technology, due to its smaller contact surfaces, requires other measures, in particular securing the plate. The plate itself does not need to be shaped in any particular way, in its simplest form, it can be used to grip the stops without any special edge shape.

15 Special disc formats may be required if special control tasks are required.

An additional possibility of positioning the stops of the strip is that the strip has window-like holes, whereby the corresponding edges of these holes form the stop surfaces. In such a structure, the plate must have a strip acting with the window-shaped holes so that this strip engages this stop as the panel turns back.

The tubular fastener of Figures 1-3 consists of halves 1 and 2. The halves 1, 2 are joined together in a flexible manner, which is done here by means of a screw 3. To this end, the half 1 has a flange portion 4 and the other half has a flange portion 5. The screw 3 is secured to the flange portion 4 by an internal thread 4a and passes through the long hole 5a of the flange portion 5.

For securing the bracket, for example by means of a threaded rod, the half 1 further has a thread nut 6.

The other half 2 has a flange 8. It is provided with a through opening 8a and its end 8b bends downwards. The through opening 8a of the flange 8 is partially covered by a plate 9 which engages the flange 8 by a joint. The plate 9 has a tongue 9a for forming a joint which engages the recess 8c of the flange 8.

Figs. 2 and 3 show how the plate 9 engages with the toothed projection 7a in the closed position of the tube bracket and is fully reversed by the action of the spring 10. This is thus a closed position of the pipe clamp, where it no longer opens automatically. If the pipes are not tight enough in this position, it is possible to tighten them by tightening the screw 3.

Figures 4 and 5 show an embodiment of a pipe clamp that differs from the pipe clamp of Figures 1-3 only with respect to the closure. Thus, it also has halves 11 · 104386 6 and 12 having flange portions 14, 15. The joint 13 of the screw 13 and the flange portions 14, 15 forms a flexible joint such that the screw 13 is in the inner thread 14a of the flange portion 14 and passes through the long bore 15a .

5 Half 11 again has a threaded nut 16 for attaching the pipe clamp, for example to a threaded rod.

The bracket half 11 has a list of window-shaped holes 17a forming the stop surfaces 17b for forming the stops. The second half-10 socket 12 has a flange 18 having a through hole 18a. The through hole 18a of the flange 18 is covered by a plate 19 disposed between the outer periphery of the half 12 and the projection 18b of the flange 18. The plate 19 engages with a joint formed by the tongue 19a of the plate 19 and the recess 18c of the flange 18.

4 and 5, the tongue 19a of the tongue 19 engages the tongue 20 which rests on the flange 18.

In particular, Fig. 5 shows that the plate 19 is provided with a strip 19b which engages with the window-shaped holes 17a and is important with the impact surfaces 17b for effect. Also in this embodiment - as shown in particular in Fig. 5 - the strip 17 can be made by bending the edges of the half 11 so that no special treatment is needed, but the center.
