III., Description of the invention

The invention relates to a pipe clamp which consists of two half-ring-shaped clamp halves. One half of the clamp, hereinafter referred to as the upper clamp half (i), has a fastening option (2) with the aid of which the clamp can be fastened to the component supporting it. This fastening option can, for example, consist of a welded-on nut with the aid of which the further connection to the fastening point is made.

The other clamp half is referred to as the lower clamp half (3).

The two clamp halves each end in radially bent flanges (4) at which the clamp halves are connected to each other. The clamp halves are connected on at least one side of the clamp using a screw. This screw connection (5) is the subject of this invention.

On the opposite side, the flanges of the clamp halves can also be connected by a screw, but also by a movable joint or in another sensible way. The type of this connection is irrelevant for the above invention.

For a screw connection of the clamp halves according to the invention, the upper clamp half has at least one flange which has a threaded hole (6.) for receiving the connecting screw.

The opposite flange of the lower clamp half has a hole with a side opening through which the screw can be inserted. . This allows the two clamp halves to be connected to each other without the screw having to be unscrewed from the threaded hole in the upper clamp half. -

The basic design of such a lateral closure of a pipe clamp is known state of the art.

Without further precautions, however, such a closure has the major disadvantage that when a pipe is moved in a pipe clamp that has only been loosely pre-assembled, the lower half of the pipe clamp can twist to one side relative to the upper half because the screw slides out of the side recess of the flange of the lower half of the clamp. This opens the closure of the clamp, with the result that the pre-assembled pipe can fall down, which can have serious consequences.

The invention described below is about creating a locking mechanism that holds the screw in the laterally open hole (7) of the clamp base and thus prevents the clamp from opening accidentally, e.g. when the pipe is moved. <

At the same time, it is important that the production of this closure is simple and cost-effective and can be carried out in one operation with the other punching processes in the production of the clamp blank.

This invention solves this problem by punching a nose-like protuberance (8) into the side of the lateral recess in the flange of the clamp base facing the inside of the clamp, the head of the connecting screw resting on the tear-off edge (9) when the clamp is closed. Due to its sharp design, this tear-off edge forms a safe barrier against the screw slipping out of the flange opening and thus against the lock being opened inadvertently.

Since the screw head slides over the slanted edge of the protrusion when the clamp is closed, the closing movement is not hindered.

The closure designed in this way meets the requirements for a secure locking of the locking screw when the clamp is closed, a simple, unhindered closing of the clamp and uncomplicated production without additional work steps.

Claims (4)

T.P.G.TRANSFERPROJEKT GmbH Utility Model Application Page 2 of 5 ■- .- - dated-30.06.98 .-..v..· II. Protection claims 1. Pipe clamp with a laterally opening closure, consisting of two ring-shaped clamp halves (1), (2) each with at least one radially bent flange, the flanges of the clamp halves being opposite one another and serving to connect the clamp halves to one another, and the flange of the upper clamp half having a threaded hole (6) into which a screw is screwed, while the flange of the lower clamp half having a hole with a recess (7) leading to the side of the clamp band, characterized in that this recess runs parallel to the circle of rotation (Fig. 2) that the lower clamp half describes when the clamp is opened and closed, the circle of rotation having the connection of the opposite clamp connection as its center point (10). 2. Pipe clamp according to claim 1, characterized in that the recess on the flange of the clamp base has a nose-shaped protuberance (8) on the side facing the inside of the clamp. ·.. . · ^&Lgr; , 3. Pipe clamp according to claim 1 and 2, characterized in that the nose-shaped protuberance is designed in such a way that it forms a tear-off edge (9) on the inside of the bore in the pipe clamp lower part, which edge faces the head of the screw pivoted into the bore and thus ensures that the screw is locked in the pivoted-in state. 4. Pipe clamp according to claim 1 to 3, characterized in that the nose-shaped protuberance forms an inclined plane (11) towards the open side of the clamp band, over which the screw head easily slides when closing the clamp, thus enabling unhindered closing of the clamp.
