Closure for connecting two thin walls
First Claim
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.

Abstract
A closure, for connecting two thin walls, such as a sheet metal cabinet door to a sheet metal cabinet frame is disclosed, which comprises a bearing piece, arranged in or on an opening in the first thin wall and a shaft, retained in the bearing piece and which may be rotated and axially displaced therein. A pivoting lever is mounted on the on outer end of the shaft and, on the other inner end of the shaft, a retaining piece is arranged, which may be engaged with an opening in the second thin wall. The retaining piece comprises 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 projects from said sleeve piece in the direction of the wall plane which, in the locked position, extends beyond the outer surface of the guide piece as far as the rear surface of the second thin wall and rests thereon.

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.
