Abstract
A closure device having a lock element that can be locked on a mating piece, preferably for closing a sealing flap of an opening, in particular an inspection flap, preferably in a drywall construction, in particular for a wall or a ceiling is provided. A closure device is distinguished by the fact that the lock element is arranged in such a way that, preferably under the action of a spring, in a first position with respect to the mating piece it is or can be moved into a locking position and, in a second position, it reaches a position and/or a state without any blocking action.
Claims21
A closure device comprising:
- a lock element that locks on a planar mating piece, wherein said lock element has a latching jaw and has an operative rotational range of motion of approximately 180 degrees;
- a holder having a pair of peripheral edges and a top edge and which moves relative to said mating piece comprising a shaft, such that said lock element is pivotably mounted on said shaft, the shaft positioned on an end of the lock element away from the latching jaw;
- a rotational spring secured to said holder and said lock element such that under the action of said rotational spring, said lock element rotates from a first position where said lock element is locked on said mating piece to a second position, where said lock element reaches a state without any blocking action;
- said rotational spring is mounted about said shaft and applies a rotational biasing force to said lock element in a direction transverse to the direction of motion of said holder, wherein said lock element rotates in a direction transverse to the direction of motion of said holder;
- said locking element being configured and dimensioned to be completely within said peripheral edges, and said top edge in a closing position in said first position as said holder moves transversely relative to the mating piece, and in said second position, said locking element is moved perpendicularly to said holder through action of said rotational spring as said holder moves further relative to said mating piece in a direction of travel.

A closure device, comprising:
- a locking element, with a latching jaw, that pivotally mounts on a shaft, said shaft positioned on an end of said lock element away from said latching jaw and locks on a mating piece, wherein said locking element has an operative rotational range of motion of approximately 180 degrees;
- a holder upon which said lock element is pivotably mounted, said holder defining a slot in which said locking element pivots and which completely encloses said locking element in a closing position when said holder is engaging the mating piece;
- and
- a rotational spring mounted on said shaft and including two ends, one of said ends secured to said holder and the other of said ends secured to said lock element such that said rotational spring biases said locking element toward an open position transverse to a direction of motion of said holder relative to the mating piece, wherein said biasing force is applied perpendicularly to the direction of motion of said holder, wherein said lock element rotates in a direction transverse to the direction of motion of said holder.

A closure device, comprising:
- a locking element, with a latching jaw, that pivotally mounts on a shaft, said shaft positioned on an end of said lock element away from said latching jaw and locks on a planar mating piece;
- a holder upon which said lock element is pivotably mounted, said holder defining a slot in which said locking element pivots and which completely encloses said locking element in a closing position when said holder is engaging the mating piece;
- and
- a rotational spring mounted on said shaft and including two ends, one of said ends secured to said holder and the other of said ends secured to said lock element such that said rotational spring biases said locking element toward an open position transverse to a direction of motion of said holder relative to the mating piece, wherein said biasing force is applied perpendicularly to the direction of motion of said holder, wherein said lock element rotates in a direction transverse to the direction of motion of said holder,
- wherein the mating piece is planar, and defines an opening, said holder being dimensioned so that when said locking element is in said first position, said holder and said locking element pass through said opening.
