Definitions
- the invention relates to a hose clamp after
- hose clamps The closing of the hose clamp takes place either by a screw or a locking mechanism. All these hose clamps have in common that the force does not attack evenly on the circumference, since the force is introduced at the closure of the hose clamp. These hose clamps are not fully exposed to the surface of the hose because they have a beginning and an end that either overlap or nearly touch. As a result, the contact forces of a closed hose clamp are not evenly distributed over the circumference of the hose. For the operation, a tool, e.g. a screwdriver, required.
- Object of the present invention is to distribute the contact forces evenly and to the full extent of the hose clamp and to simplify the operation of the hose clamp.
- the object is achieved by a hose clamp with the features of claim 1. Further developments are specified in subclaims.
- the structure of the invention is minimalistically simple and consists of two annular, nested components, namely an inner and an outer ring. These have mutually eccentric rotatable inner openings, resulting in a variable inside clear width of the hose clamp.
- the hose clamp can be closed without tools using simple steps, by turning the outer ring and inner ring against each other.
- the hose clamp In order to be able to follow the diverse requirements with regard to chemical, mechanical, thermal and UV resistance, it may be necessary to manufacture the hose clamp from different materials. It may also be helpful not to make the inner ring and outer ring from the same material.

- Figure 2 is a representation of the outer ring

- FIG. 6 is an illustration of an outer ring variant with openings and webs
- a hose clamp carries in the figures 3 to 5 in total the reference numeral 1. It comprises an outer ring 2 and a
- FIG. 1 shows an inner ring.
- the inner ring 3 is characterized in that the center 4 of an inner diameter 5 is offset by a distance X from a center 6 of an outer diameter 7 (ie, a circular inner opening 8 is eccentric to a circular outer periphery 9).
- Figure 2 shows an outer ring.
- the outer ring 2 is characterized in that it is wider and larger than the inner ring 3.
- An outer diameter 11 of the outer ring 2 is greater than the outer diameter 7 of the inner ring 3 are the same size.
- the outer diameter 11 and the inner diameter 10 of the outer ring 2 have the same center 12, so are arranged concentrically.
- the outer ring 2 is provided on its inner surface with a circumferential groove 13, which can preferably accommodate the inner ring 3 in a so-called zero position (see Figure 3) preferably completely.
- the center 14 of a groove diameter 15 is at the center of the inner diameter 12 of the outer ring 1 by the same
- the groove 13 is thus arranged eccentrically relative to the inner opening 16 of the outer ring 2.
- the width of the groove 13 corresponds approximately to a width of the inner ring third
- the hose clamp 1 is characterized overall in that the groove 13 eccentric to the inner opening 16 of the outer ring 2 and the inner opening 8 of the inner ring 3 are eccentric to the outer circumference 9 of the inner ring 3.
- the material is to be chosen so that the inner ring 3 can be slightly deformed and after insertion into the groove 13 assumes its original shape or the outer ring 2 is constructed so that it can be opened and closed again ,
- outer ring 2 and inner ring 3 can be rotated relative to each other.
- the inner ring 3 is preferably in the groove 13, that the inner diameter of 5.10 both rings 2.3 are congruent, so the inner openings 8,16 of both rings 2,3 are concentric.
- the hose clamp 1 is used as follows:
- FIG. 3 shows a hose clamp 1 in its zero position.
- the hose clamp 1 is pushed in its zero position via a hose 17 which is to be fastened on a pipe 18.
- the outer tube diameter must be smaller than the largest opening width 19 of the hose clamp 1 in the zero position ( Figure 3).
- the largest clear opening width 19 of the hose clamp 1 in the zero position (FIG. 3) is the same size as the inner openings 8, 16 of the two rings (inner ring 3 and outer ring 2).
- the diameter of the tube 18 plus surrounding tube 17 must be greater than a minimum opening width 19 of the
- Hose clamp 1 in an end position ( Figure 5). Turning now on the hose clamp 1, only the outer ring 2 is twisted, and the inner ring 3 remains stationary, since the friction between hose 17 and hose clamp 1 is greater than the friction between the inner ring 3 and the outer ring 2. By this relative rotation between Inner ring 3 and
- Outer ring 2 reduces the clear opening width 19 of the hose clamp 1.
- Hose clamp 1 is now formed from segments of the inner openings 8,16 of the two rings (inner ring 3 and outer ring 2). During the closing process, the clear opening width 19 (inner diameter) of the hose clamp 1 loses its circular shape.
- the material of the hose clamp is to be chosen so that the hose clamp 1 can create the closing of the circular contour of the pipe.
- the hose clamp 1 can be operated manually without tools.
- FIG. 4 shows a middle position of the hose clamp 1 during the closing process.
- the position of the inner ring 3 is unchanged.
- the outer ring 2 is rotated by 90 ° with respect to the zero position ( Figure 3) counterclockwise.
- the clear opening width 19 of the hose clamp 1 is reduced.
- Figure 5 shows in the end position an unchanged position of the inner ring 3.
- the outer ring 2 is now rotated by 180 ° with respect to the zero position ( Figure 3) counterclockwise.
- the clear opening width 19 of the hose clamp 1 (formed from segments of the inner openings 8, 16 of the two rings 2, 3) is reduced in such a way that the hose clamp 1 rests firmly against the hose 17 and urges the hose 17 radially inward and thus on the pipe 18 fixed.
- a clamping action inhibits the two rings 2,3
- Attack surfaces are attached, where a tool can be attached.
- the outer ring 2 may have at its periphery one or more elongated openings. On the outer circumference of the
- Inner rings 3 may be visible, e.g. color markings are attached. Through the openings so the position of the outer ring 2 relative to
- Inner ring 3 and the direction to open or close are detected.
- FIG. 6 shows an outer ring 2 with openings 20 and webs 21 arranged on the circumference.
