Abstract

A lock for holding a first part to a second part comprises a holding body with a receptacle for receiving a protruding part of the second part. The holding body has a wall that borders the receptacle and a locking element, the locking element having a protrusion, whereby the locking element has a first position, whereby in the first position the protrusion is in a locking position, whereby in the locking position the protrusion protrudes from the wall into the receptacle by a first amount and the locking element has a second position, whereby in the second position the protrusion is in a release position, whereby in the release position the protrusion either protrudes from the wall into the receptacle by a second amount, whereby the second amount is smaller than the first amount, or the protrusion does not protrude from the wall.

First claim

What is claimed is:

1. A lock for holding a first part to a second part, the lock comprising:
a holding body configured to be mounted to the first part, the holding body configured with a receptacle for receiving a protruding part of the second part, the holding body having a wall that borders the receptacle,
a linearly moveable locking element, the locking element having a protrusion, wherein
the locking element is moveable to a first position, whereby in the first position the locking protrusion is in a locking position, whereby in the locking position the protrusion protrudes from the wall into the receptacle by a first amount, such that the protrusion can retain the protruding part within the receptacle, and
the locking element is moveable to a second position, whereby in the second position the protrusion is in a release position, whereby in the release position:
the protrusion either protrudes from the wall into the receptacle by a second amount, whereby the second amount is smaller than the first amount, or
the protrusion does not protrude from the wall into the receptacle,

such that the protruding part can be moved into and released from the receptacle,
wherein when the protrusion is moved from the locking position to the release position the protrusion moves in a retraction direction relative to the holding body, and
a pair of levers, whereby, for at least one of the pair of levers:
the lever has a first end and a second end that is arranged opposite the first end, whereby the protrusion is attached to the first end of the lever, and the lever is or can be moved into a position, where the lever rests against a a protruding piece of the holding body at a point of contact, and when in contact with the protrusion the lever can be swiveled about the protruding piece or the lever is connected to the holding body by a rotational joint, whereby the point of contact or the rotational joint is arranged between the first end and the second end of the lever, and
applying a force to the second end that is directed against the retraction direction leads to:
a swivel movement of the lever about the protruding piece or in the rotational joint, and
a movement of the protrusion in the retraction direction.

2. The lock according to claim 1 , wherein the pair of levers further comprising a second lever, whereby
the second lever has a first end and a second end that is arranged opposite the first end, whereby the protrusion is attached to the first end of the lever and the first end of the second lever, and
the second lever is or can be moved into a position, where the second lever rests against a second protruding piece of the holding body at a point of contact, and when in contact with the second protruding piece can be swiveled about the second protruding piece or the second lever is connected to the holding body by a second rotational joint, whereby the point of contact or the second rotational joint is arranged between the first end and the second end of the second lever, and
applying a force to the second end of the second lever that is directed against the retraction direction leads to:
a swivel movement of the second lever about the second protruding piece or in the second rotational joint, and
a movement of the protrusion in the retraction direction.

3. The lock according to claim 2 , further comprising a bridge that connects the second end of the lever with the second end of the second lever.

4. The lock according to claim 1 , further comprising a guide surface, whereby a surface of the protrusion and/or a surface of a part of the locking element that is fixedly connected to the protrusion interacts with the guide surface such that the protrusion is guided to move from the locking position to the release position in the retraction direction.

5. The lock according to claim 1 , wherein a locking protrusion is arranged at the second end of the lever, whereby the locking protrusion can releasably engage with a part of the holding body to hold the lever in a predetermined swivel position.

6. The lock according to claim 1 , wherein a guide arm is arranged at the second end of the lever, whereby the guide arm is arranged in a channel in the holding body and can be moved along the channel, thereby guiding the movement of the second end of the lever.

7. The lock according to claim 6 , wherein the second end of the lever is connected to the locking protrusion and/or the guide arm by a hinge.

8. The lock according to claim 1 , wherein the first end of the lever is connected to the protrusion by a hinge.

9. An assembly of a first part and a second part, whereby
the first part is connected to the holding body of the lock according to claim 1 ,
the second part comprises a protruding part with an opening or a recess, whereby
the protruding part is arranged in the receptacle, and
the protrusion of the locking element is in the first position and at least partially arranged inside protruding part.

10. A method for disassembly of the assembly according to claim 9 , wherein
a force is applied to the second end that is directed against the retraction direction, which leads to a swivel movement of the lever about the protruding piece or in the rotational joint and a movement of the protrusion in the retraction direction into the second position the protrusion is in a release position, whereby in the release position:
the protrusion either protrudes from the wall into the receptacle by a second amount, whereby the second amount is smaller than the first amount, or
the protrusion does not protrude from the wall, and

the u-shaped protruding part is moved out of the receptacle.
