Description

Ear clamp.

The invention relates to a pipe clamp that consists of two opposite straps, which at one end interlock with each other * gripping means are connected and bent so that they together include a üohr, while the other Ends can be tensioned together by means of bolts or the like and wherein said connecting means does not or almost does not protrude beyond the circumference of the tabs.

Such a saddle is described in French patent specification 647 _f 789. In this known drill saddle, the interlocking means are formed by complementary lips and recesses in the tabs, which are dovetail-shaped, so that forces can be transmitted in the plane of the tabs.

This embodiment is particularly suitable for relatively heavy drill jacks, with the thickness of the tabs used is at least a few millimeters. However, the construction is less suitable when the thickness of the flaps becomes smaller, since then there is a possibility that the flaps move each other if they do not fit very precisely around the drill, that is, if the dimensional deviations of the drill and / or the bent tabs are too large. The present invention now provides one Drill clamp, which can be used especially where less stringent requirements are set, so that the clamp can be made from thinner tabs without the difficulty described above.

The ear clamp according to the present invention is marked, by forming the interlocking means so that it is close to the end of the bent Part of the two tabs (1,2) is a slot (4,5) which is transverse to the longitudinal direction of the tab and extends to about half its width and the two tabs in the longitudinal direction of the drill (3) are slidable into one another.

In order to limit the width of the slots and to ensure that, viewed over the outer circumference, none protruding parts are present, is according to the

209815/1037

2U8116

Finding further provided that at least that part of the end located at the slot or outside this of the two tabs is bent out of the semicircular shape in such a way that the two ends are in the assembled position the .pipe clamp are approximately in contact with the pipe

For this purpose, the ends of the two tabs can be bent over approximately 1/4 of the circumference so that they are directed from the pipe wall, while the remaining part of the tab at the slot is strongly bent towards the pipe wall and after the slot again on the pipe wall However, it is also possible to bend the tabs in such a way that most of them lie against the wall of the pipe, while at a short distance in front of the slot the tab is provided with an outwardly projecting part in which the end of the counter tab is received can. The course of the flap is then roughly intermittent. This ensures that the flaps now lie over a major portion directly to the pipe wall, the connection is something to be stronger, which is advantageous because it is less space between the plates and the pipe ^w, §ich any dirt can accumulate ·

The new type of pipe clamp also has the advantage that both tabs are completely similar to one another. The invention is explained on the basis of two exemplary embodiments, which show in the drawing:

Fig. 1 is a side view of the pipe clamp according to the present invention;

Flg. Figure 2 is an end view of the junction of the two tabs from which the pipe clamp of Figure 1 is assembled;

3 shows a top view of the pipe clamp according to FIG. 1;

4 is a plan view of a somewhat modified embodiment of the pipe clamp.

The pipe clamps shown in the drawing consist of the Essentially from the two tabs 1 and 2. One end of each tab is rounded to enclose one Tube 3, while the two ends of the tabs are connected to each other by making a slot 4 in the tab 1 and a slot 5 in the flap 2 are connected

The slots 4 and 5 run in the longitudinal direction of the ear 3 and up to about half the width of tabs 1 and 2, so that the tabs are pushed into one another in the transverse direction can.

When using the clamp, bolts will be in the opening provided, which are located in the ends of the tabs which are directed away from the tube 3.

In the embodiment according to FIGS. 1, 2 and 3 have the bent parts of the tabs have a radius of curvature,

which is slightly larger than the radius of the outer diameter of the ear. At the location of the slots 4, 5 the tabs are closed on the inside, that is to say to the Pipe wall bent and then bent back in a direction approximately parallel to the pipe wall. As a result, the pipe clamp has almost no protruding parts that could injure body parts or cause clothing to tear.

Furthermore, the manufacture of the tabs is particularly simple. A single device can be used for different strap widths are used and the two tabs of a pipe clamp are, as already stated, perfect one another same.

FIG. 4 shows another embodiment in which the tabs rest against the tube over a larger part and are only bent outwards at a short distance from the slots 4 and 5 in order to accommodate the end to enable the counter flap.

Only a few embodiments are described and changes can be made without the concept of the invention to leave. That's how it is in. Principle possible, for example, the ends of the tabs with several To provide slots and to arrange a single connecting piece between the ends of the tabs.

Claims (2)

PATENT CLAIMS: 1.) Pipe clamp, which consists of two opposing lugs, which are connected to one another at one end by means of interlocking means and bent in such a way that they together encompass a drill hole, while the other ends can be tensioned together by means of bolts or the like and wherein the said connecting means do not or almost not protrude beyond the circumference of the tabs, characterized by the design of the interlocking means such that near the end of the bent part of the two tabs there is a slot which is transverse to the longitudinal direction of the tab and up to approximately extends in half the width and the two tabs can be pushed into one another in the longitudinal direction of the tube. 2. Pipe clamp according to claim 1, characterized in that at least that part of the end of the two tabs located at the slot or outside this is bent out of the semicircular i'orm in such a way that the ends in the assembled position of the pipe clamp almost rest against the drill - · 209815/1037
