Claims
- 1. A closure for connecting two thin walls, like a sheet metal cabinet door and a sheet metal door frame to each other, comprising:a bearing piece being arranged in or on an opening in a first thin wall, such as a door; a shaft being retained in the bearing piece and which may be rotated and axially displaced therein; on an outer end of said shaft, a pivoting lever being mounted, which can be pivoted on an axis that is vertical to an axis of the shaft; on an inner end of the shaft, a retaining piece being arranged, wherein the pivoting lever can be pivoted from a first open position in which the shaft is in a first axial thrust exerting position, into a second closed position in which the shaft is displaced axially outward towards the pivoting lever against the force of a spring; said retaining piece comprising a cupular guide piece and a sleeve piece, which may be inserted in and rotated in the cupular guide piece against the force of a spring; a catch projecting from said sleeve piece in the direction of the wall plane; and in a locked position, the projecting of the catch extends beyond an outer surface of the guide piece as far as a rear surface of a second thin wall and rests thereon; wherein a sleeve bearing and a catch sleeve are held on the shaft by a self-locking nut.
- 2. The closure according to claim 1, wherein an opening arranged in the second thin wall is circular with widening portions preferably arranged opposite to each other and wherein the catch can, in the manner of a bayonet, be passed through an opening in a first rotary position of a rotating sleeve but not in another position.
- 3. The closure according to claim 1, wherein the lever forms a cam surface which rests on an outside face of the bearing piece.
- 4. The closure according to claim 1, wherein an outside face of the bearing piece forms a groove in the shape of part of a circle or of a conical depression into which a lug formed or carried by the lever dips during the closing pivoting movement of the lever.
- 5. The closure according to claim 1, wherein a spring washer is arranged between the self-locking nut and the catch sleeve.
- 6. The closure according to claim 1, wherein the outside surfaces of the catch or the cupular guide piece have a conical shape.
- 7. The closure according to claim 1, wherein sealing devices are provided which seal off spaces separated by the first thin wall from each other.
- 8. The closure according to claim 1, wherein the spring force originates from a spiral pressure spring arranged between the cup bottom of the guide piece on one side and the annular face of the sleeve pointing towards the cup bottom.
- 9. The closure according to claim 8, wherein the catch is passed through the opening at a 90 degree rotary offset.
- 10. The closure according to claim 8, wherein the shaft is eccentric relative to the outside circumference of a cup.
- 11. The closure according to claim 1, wherein the thin wall has openings into which lugs protruding from the bearing piece penetrate.
- 12. The closure according to claim 11, wherein instead of the lugs, threaded boreholes are provided into which countersunk head screws, can be screwed which have been passed through the openings provided in the first thin wall.
- 13. The closure according to claim 1, wherein a projection extends from the outside of the bottom of the cupular piece which can be received by a correspondingly shaped opening in the thin wall in such a way that the cupular guide piece is secured against rotation relative to the first thin wall.
- 14. The closure according to claim 13, wherein the projection has a non-round cross-section which can be held by the opening in the thin wall with a non-round cross-section in a manner that is secured against twisting.
- 15. The closure according to claim 13, wherein the opening in the first thin wall is an elongated hole which can hold a cross-section of the projection and the shaft without play.
- 16. The closure according to claim 13, wherein the opening in the first thin wall is an elongated hole which can hold the cross-section of the projection and the shaft with some play.
- 17. A closure for connecting two thin walls, like a sheet metal cabinet door and a sheet metal door frame to each other, comprising:a bearing piece being arranged in or on an opening in a first thin wall, such as a door; a shaft being retained in the bearing piece and which may be rotated and axially displaced therein; on an outer end of said shaft, a pivoting lever being mounted, which can be pivoted on an axis that is vertical to an axis of the shaft; on an inner end of the shaft, a retaining piece being arranged, wherein the pivoting lever can be pivoted from a first open position in which the shaft is in a first axial thrust exerting position, into a second closed position in which the shaft is displaced axially outward towards the pivoting lever against the force of a spring; said retaining piece comprising a cupular guide piece and a sleeve piece, which may be inserted in and rotated in the cupular guide piece against the force of a spring; a catch projecting from said sleeve piece in the direction of the wall plane; and in a locked position, the projecting of the catch extends beyond an outer surface of the guide piece as far as a rear surface of a second thin wall and rests thereon; wherein the spring force originates from a spiral pressure spring arranged between the cup bottom of the guide piece on one side and the annular face of the sleeve pointing towards the cup bottom.
- 18. A closure for connecting two thin walls, like a sheet metal cabinet door and a sheet metal door frame to each other, comprising:a bearing piece being arranged in or on an opening in a first thin wall, such as a door; a shaft being retained in the bearing piece and which may be rotated and axially displaced therein; on an outer end of said shaft, a pivoting lever being mounted, which can be pivoted on an axis that is vertical to an axis of the shaft; on an inner end of the shaft, a retaining piece being arranged, wherein the pivoting lever can be pivoted from a first open position in which the shaft is in a first axial thrust exerting position, into a second closed position in which the shaft is displaced axially outward towards the pivoting lever against the force of a spring; said retaining piece comprising a cupular guide piece and a sleeve piece, which may be inserted in and rotated in the cupular guide piece against the force of a spring; a catch projecting from said sleeve piece in the direction of the wall plane; and in a locked position, the projecting of the catch extends beyond an outer surface of the guide piece as far as a rear surface of a second thin wall and rests thereon; wherein an outside face of the bearing piece forms a groove in the shape of part of a circle or of a conical depression into which a lug formed or carried by the lever dips during the closing pivoting movement of the lever.
