Abstract

A catch device (1) for connecting a handle to a vacuum cleaner suction pipe (2), the catch device (1) being mountable on one end region of a vacuum cleaner suction pipe (2), and having at least one sleeve (3), at least one lever button (4) and at least one reset spring (7), the lever button (4) having a catch projection (8) and a pivot axle (9) for the lever button. The catch device (1) reduces the effort for mounting on a vacuum cleaner suction pipe (2) the provision of a clamp element (11) that is positively connected to the sleeve (3), the pivot axle (9) being pivotally held between the clamp element (11) and the sleeve (3).

Claims

1. A catch device for connecting a handle to a vacuum cleaner suction pipe, wherein the catch device is mountable on a end region of a vacuum cleaner suction pipe, comprising:

at least one sleeve,

at least one manually depressible lever button mounted at an inner side of the sleeve so as to be depressible from an outer side of the sleeve to pivot about a pivot axle, and

at least one reset spring,

wherein the sleeve is a carrier for the at least one manually depressible lever button and the at least one reset spring,

wherein the lever button comprises a catch projection,

wherein a clamp element is directly connected to the sleeve,

wherein the pivot axle is pivotally held in a fixed position being clamped between the clamp element and the sleeve,

wherein the clamp element has two catch flanks which are located parallel to one another, and

wherein the sleeve has two catch regions which correspond to the catch flanks.

2. The catch device as claimed in claim 1, wherein the catch flanks run parallel to an axial direction of the sleeve.

3. The catch device as claimed in claim 1, wherein the clamp element is located on an inner side of the sleeve so that the clamp element, in a mounted state of the catch device will face the vacuum cleaner suction pipe.

4. The catch device as claimed in claim 1, wherein the reset spring is supported between the sleeve and the lever button, wherein the reset spring acts on the lever button to force it toward a locking position.

5. The catch device as claimed in claim 1, wherein the clamp element has a recess for the catch projection.

6. The catch device as claimed in claim 1, wherein the clamp element has a stabilization bridge for guidance of the lever button.

7. The catch device as claimed in claim 6, wherein the stabilization bridge is arranged extending parallel to the axial direction of the sleeve.

8. The catch device as claimed in claim 1, wherein the sleeve comprises at least one first half shell and at least one second half shell.

9. The catch device as claimed in claim 8, wherein the lever button, the reset spring and the clamp element are located on the first half shell.

10. A catch device for connecting a handle to a vacuum cleaner suction pipe, wherein the catch device is mountable on a end region of a vacuum cleaner suction pipe, comprising:

at least one sleeve,

at least one manually depressible lever button mounted at an inner side of the sleeve so as to be depressible from an outer side of the sleeve to pivot about a pivot axle, and

at least one reset spring,

wherein the sleeve is a carrier for the at least one manually depressible lever button and the at least one reset spring,

wherein the lever button comprises a catch projection,

wherein a clamp element is directly connected to the sleeve,

wherein the pivot axle is pivotally held in a fixed position being clamped between the clamp element and the sleeve, and

wherein at least one first part of a guide bush for the pivot axle is located on the sleeve and at least one second part of the guide bush is located on the clamp element so that the pivot axle of the lever button is guided in the guide bush between the clamp element and the sleeve.

11. A vacuum cleaner suction pipe assembly, comprising

at least one vacuum cleaner suction pipe,

a catch device for connecting a handle to the vacuum cleaner suction pipe, wherein the catch device is mountable on a end region of a vacuum cleaner suction pipe, comprising:

at least one sleeve,

at least one manually depressible lever button mounted at an inner side of the sleeve so as to be depressible from an outer side of the sleeve to pivot about a pivot axle,

at least one reset spring,

wherein the sleeve is a carrier for the at least one manually depressible lever button and the at least one reset spring,

wherein the lever button comprises a catch projection,

wherein a clamp element is directly connected to the sleeve,

wherein the pivot axle is pivotally held in a fixed position being clamped between the clamp element and the sleeve,

wherein the clamp element has two catch flanks which are located parallel to one another, and

wherein the sleeve has two catch regions which correspond to the catch flanks.
