Abstract
A locking system for a movable member supported by a support frame, the support frame having an engagement surface, the locking system comprising a lock member and an input device adapted to be mounted on the movable member the input device being operably connected to the lock member. The input device is rotatable to move the lock member from a first position to a second position, the second position defining a locked position wherein the lock member is adapted to be in contact with the engagement surface. The locking system also includes a link arm and a spring that permits additional rotation of the input device after the lock member reaches the locked position, if necessary.
Claims31
A locking system for a movable member supported by a support frame, the support frame having an engagement surface, the locking system comprising:
- an input device adapted to be mounted on the movable member and rotatable between a first position and a second position;
- a lock member having a lock surface;
- and
- a spring having a first end connected to the input device and a second end connected to the lock member;
- wherein the spring moves the lock member in response to rotational movement of the input device from the first position to an intermediate position wherein the lock member moves from an unlocked position to a locked position wherein the lock surface contacts the engagement surface, wherein the spring elongates to allow further rotation of the input device to the second position.
A locking system for a movable member supported by a support frame, the support frame having an engagement surface, the locking system comprising:
- an input device adapted to be mounted on the movable member and rotatable between a first position and a second position;
- a link arm having a first end and a second end, the first end being connected to the input device;
- a lock member having a lock surface, the lock member being associated with the link arm;
- and
- a spring having one end connected to the link arm and another end connected to the lock member;
- wherein the link arm and spring move the lock member in response to rotational movement of the input device from the first position to an intermediate position wherein the lock member moves from an unlocked position to a locked position wherein the lock surface is configured to contact the engagement surface, wherein the operable connection between the link arm and lock member allows the link arm to move relative to the lock member to allow further rotation of the input device to the second position.
A locking system for a door movably mounted in a door frame, the door frame having an engagement surface, the locking system comprising:
- an input device adapted to be mounted on the door and rotatable from a first position to a second position;
- a link arm having a first end and a second end, the first end being connected to the input device;
- a lock member having a lock surface, the lock member being associated with the link arm;
- and
- a spring having a first end connected to the link arm and a second end connected to the lock member;
- wherein the link arm and spring move the lock member in response to rotational movement of the input device from the first position to an intermediate position wherein the lock member moves from an unlocked position to a locked position wherein the lock surface is configured to contact the engagement surface, wherein the operable connection between the link arm and lock member allows the link arm to move relative to the lock member to allow the input device to be further rotated to the second position.
A locking system for a door movably mounted in a door frame, the door frame having a tab having an engagement surface, the locking system comprising:
- an input device adapted to be rotatably mounted in the door from an unlocked position to a locked position;
- a link arm having a first end and a second end, the first end being connected to the input device, the second end having a slot therein;
- a lock member having an aperture defining a lock surface, the lock member having a pin positioned in the slot of the second end of the link arm;
- a spring having one end connected to the link arm and another end connected to the pin;
- wherein the link arm and spring move the lock member in response to rotational movement of the input device from the unlocked position to an intermediate position wherein the lock member moves from an unlocked position to a locked position wherein the aperture is configured to receive the tab wherein the lock surface is adapted to contact the engagement surface, the pin being allowed to slide in the slot of the link arm to allow further rotation of the input device and link arm wherein the input device can be further rotated from the intermediate position to the locked position when the lock member is in the locked position.
