Abstract
Abstract The invention relates to an apparatus for detachably connecting two parts. It has a receiving part (1) which possesses a housing (3a). A lock (5a) which has a bevelled entrance (7a) is mounted in the housing (3a). A locking pin (9d) having a displacement part (12a) is used for locking or for latching with the lock (5a), which is kept pressed in the locking direction by a rubber ring (16). A spring or block acts against movement of the locking pin (arrow 57). An unlocking part (11a) is mounted on the shaft of the locking pin (9d) so that the said unlocking part can slide in the direction of movement (arrow 57). The locking pin (9d) carries a thrust plate (8) on its end facing away from the displacement part (12a). If pressure is exerted on this thrust plate, the displacement part (12a) initially interlocks with the lock (5a). When further pressure is exerted in the direction of movement arrow (57), the unlocking part (11a) forces the lock (5a) apart via the bevelled entrance (7a) and against the spring force of the rubber ring (15), at right angles to the direction of movement (57). The lock (5a) then jams at the displacer contour (17) of the unlocking part (11a). The connection can thus be parted again by pulling the locking pin (9d) out of the receiving part (1). In another embodiment, the lock (5k; 1) is held on the locking pin (9m: n) and the displacement part (12k:) is held on the housing 3n; m).

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
300 words
Apparatus for detachably connecting two parts including a locking pin and a receiving part for receiving a locking pin when the locking pin is moved in an insertion direction, the apparatus comprising, a displacement part on one of the parts having a first displacer contour and a first abutment means, a spring-loaded lock on the other of the parts being moveable by the displacement part when the locking pin is moved in said insertion direction from a locking position against its spring-load into an unlocking position, and upon further insertion of the locking pin the lock being moveable into a locking position engaging the first abutment means thereby preventing removal of the locking pin from the receiving part, first spring means for biasing the spring-loaded lock into the locking position, second spring means acting against movement of the locking pin in the inserting direction, force adjusting means for adjusting the force of the second spring means, second abutment means on one of the parts, a sleeve-like unlocking part supported securely by one of the parts and retained by the first abutment means in one direction along the locking pin and the second abutment means in the opposite direction and having a second displacer contour mounted so that it is moveable along the locking pin, the minimum penetration depth of the locking pin into the receiving part corresponding to the extension of the displacement part in the direction of movement of the locking pin plus clearance and the depth of the spring-loaded lock in the direction of movement of the locking pin so that when the locking pin is moved further in said insertion direction the sleeve-like unlocking part urges the spring-loaded lock away from the first abutment means thereby allowing the locking pin to be removed from the receiving part.

Apparatus for detachably connecting two parts including a locking pin and a receiving part for receiving a locking pin when the locking pin is moved in an insertion direction, the apparatus comprising, a displacement part on one of the parts having a first displacer contour and a first abutment means, a spring-loaded lock on the other of the parts being moveable by the displacement part when the locking pin is moved in said insertion direction from a locking position against its spring-load into an unlocking position, and upon further insertion of the locking pin the lock being moveable into a locking position engaging the first abutment means thereby preventing removal of the locking pin from the receiving part, first spring means for biasing the spring-loaded lock into the locking position, second spring means acting against movement of the locking pin in the inserting direction, force adjusting means for adjusting the force of the second spring means, second abutment means on one of the parts, a sleeve-like unlocking part supported securely by one of the parts and retained by the first abutment means in one direction along the locking pin and the second abutment means in the opposite direction and having a second displacer contour mounted so that it is moveable along the locking pin, the minimum penetration depth of the locking pin into the receiving part corresponding to the extension of the displacement part in the direction of movement of the locking pin plus clearance and the depth of the spring-loaded lock in the direction of movement of the locking pin so that when the locking pin is moved further in said insertion direction the sleeve-like unlocking part urges the spring-loaded lock away from the first abutment means thereby allowing the locking pin to be removed from the receiving part.
Claim 3
Dependent Claim
48 words
Apparatus as claimed in claim 1 wherein the force of the second spring means in the direction against movement of the locking pin in the inserting direction is established by means selected from the group consisting of adjustable means, spring means, a plurality of springs and blocking means.
Claim 4
Dependent Claim
58 words
Apparatus as claimed in claim 2 wherein the locking pin has, on its end facing away from the displacement part, a thrust plate which projects the width of the unlocking part at right angles to the direction of movement, and wherein the second spring means is arranged between the housing and the thrust plate in a locked state.
Claim 5
Dependent Claim
30 words
Apparatus as claimed in claim 2, wherein the second spring means is arranged on that side of the lock which faces away from the locking pin in an unlocked state.
Claim 6
Dependent Claim

Apparatus as claimed in claim 1 wherein the force adjustment means comprise a second abutment means manually displaceable against one end of the second spring means.
Claim 7
Dependent Claim
64 words
Apparatus as claimed in claim 1 wherein extension of the unlocking part at right angles to the direction of movement is greater than that of the displacement part, and the unlocking part has an end surface which faces the displacement part of the locking pin and has an undercut in which the displacement part of the locking pin can be at least partially sunk.
Claim 8
Dependent Claim
