Abstract
A lock device is provided with a housing, a rotary member, a pair of link rods provided with a hook part, a spring for the rotary biasing of the rotary member, and an operative member mounted so as to be able to be inserted into the housing. A cam protrusions formed in the rotary member, and a wall part having a cam slope which abuts the cam protrusion is formed in the operative member. The configuration is such that by inserting the operative member, the rotary member resists the biasing force of the spring and rotates, and the hook part of the link rods slides in a position in which it does not engage with the lock part.
Claims17
A locking device for an openable/closable body that is openably/closably mounted to an opening portion of a fixed body, the locking device including:
- locking portions provided on both sides of one of the openable/closable body and the opening portion of the fixed body;
- a housing mounted to the other one of the openable/closable body and the fixed body and including a cylinder-shaped shaft portion protruding from a back surface side of the housing;
- a rotary member rotatably mounted on the back surface side of the housing around the shaft portion;
- a pair of link rods configured to slidably move in synchronization with rotation of the rotary member to make hook portions formed at distal ends thereof engage and disengage the locking portions;
- a spring arranged to bias the link rods in directions that the hook portions of the link rods engage the locking portions;
- and
- a manipulation member pushably mounted on a front surface side of the housing and including a pressing portion configured to be pushed in from a front side of the pressing portion and a protrusion protruding from a back side of the pressing portion,
- wherein one of the rotary member and the manipulation member includes a wall portion having a cam inclined surface, and the other one of the rotary member and the manipulation member includes a cam contact portion, so that a pushing force on the manipulation member is converted into a rotational force on the rotary member through contact between the cam contact portion and the cam inclined surface,
- wherein, by pushing in the manipulation member, the rotary member is rotated against a biasing force of the spring, and the pair of link rods are made to slide to positions where the hook portions of the link rods disengage the locking portions,
- wherein, in a state where the manipulation member is pushed in, the protrusion is movable within the shaft portion.
