SEMI-PROFESSIONAL CAN OPENER

Abstract

A can opener for semi-professional use includes a cylindrical functional part which is connected to a crank, that may be inserted from two sides through an annular housing which is fastened on a stand. The functional part is connected with a positive and non-positive fit with a bayonet-like closure in this housing preferably by way of screwing, to a fastening ring. By way of this design, the functional part may be quickly assembled in this housing and be removed therefrom again. The can opener may be permanently fastened on a horizontal surface or a vertical wall by a fastening means. A support rod and a support surface fastened to the same are fastened with the functional part on the housing, so that the support surface prevents cans to be opened from falling down.

Claims

1. A can opener to be actuated manually comprising a functional part for opening cans fastenable to a stand, wherein the functional part is cylindrical and comprises a crank, a cylinder axis, an abutment ring, and a fastening ring, the functional part insertable through two opposite sides of a hollow-cylindrical housing which is fastenable on the stand, and is mountable with a positive fit in a rotationally secured manner in the housing in at least one alignment relative to the cylinder axis, and securable in an axially fixed manner in the housing by way of a bayonet closure with a fastening ring, wherein the stand is fastenable with a fastening means on a vertical wall or a horizontal surface.

2. The can opener of claim 1, wherein the housing comprises at least one radially inwardly directed locking rib.

3. The can opener of claim 1, wherein the cylindrical functional part has at least one thread section which is directed radially outwards from the superficies of the functional part and which with at least one counter-thread section on the fastening ring forms a connection in the manner of bayonet closure.

4. The can opener of claim 1, wherein the abutment ring comprises at least one abutment ring recess.

5. The can opener of claim 2, wherein the at least one locking rib engages with a positive fit into the at least one abutment ring recess, by which means the functional part may be mounted in the housing in a rotationally secured manner.

6. The can opener of claim 1, wherein the housing comprises at least one radially arranged through-bore.

7. The can opener of claim 6, wherein the through-bore crosses a locking rib.

8. The can opener of claim 1, wherein the functional part comprises a thread-in milled recess shaped as a T-groove, in the outer superficies parallel to the cylinder axis.

9. The can opener of claim 8, wherein the thread-in milled recess crosses the at least one abutment ring recess.

10. The can opener of claim 6 further comprising a thread-in milled recess shaped as a T-groove, in the outer superficies parallel to the cylinder axis and wherein a support rod is positioned through the at least one through-bore and is threaded into the thread-in milled recess by way of an annular groove.

11. The can opener of claim 10, further comprising a support surface for holding opened cans at variable distances to the through-bore fastened along the support rod.

12. The can opener of claim 11, wherein the support surface via a pivot is mounted on a slider which is displaceable on the support rod such that a clamping on the support rod is effected with a pressure on the support surface.

13. The can opener of claim 10, wherein the stand comprises two stand legs and a stand foot, wherein the stand legs are distanced to one another, and at least one through-bore passes through the housing therebetween, whilst the support rod runs between the stand legs.

14. The can opener of claim 1, wherein the fastening means is a screw clamp.

15. The can opener of claim 13, further comprising a stand plate fixably held in the stand foot, and by way of this plate, the stand is rigidly mountable on a surface.
