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.

Abstract: A pressing device is provided with a pin member, a coil-like spring member, and a spring receiving member which has a through-hole for allowing the pin member to be inserted therein and which supports one end of the spring member. The pin member has: a shaft section which has the spring member disposed on the outer peripheral side thereof; a head section which is interconnected with one end of the shaft section and which can come into contact with the contact surface of the opening/closing body; a spring support section which supports the other end of the spring member; and an engagement claw which engages with the outer surface of the mounting portion and which prevents the pressing device from being dislocated from the mounting portion.

Abstract: A lock device for an opening/closing device, provided with: lock sections located on both sides of the lid; a pair of link rods provided with hook sections provided at the front ends of the pair of link rod; pressing means for pressing the hook sections in the direction in which the hook sections engage with the lock sections; a pusher for sliding the hook sections in the direction in which the hook sections do not engage with the lock sections; pressing members disposed on both sides of an opening and pressing the lid in the direction in which the lid opens; and a holding lever and a holding protrusion which hold the hook sections in a state in which the hook sections do not engage with the lock sections.

Abstract: According to an aspect of the present invention, there is provided a hinge device including: a first member having a pair of pin insertion holes; a second member having a pair of pin support holes; a pair of pin members respectively inserted into the pin insertion holes and the pin support holes to support the first member and the second member, the pin members being rotatable with respect to the pin insertion holes and not rotatable with respect to the pin support holes; a spring supported between the pin members to bring the pin members into contact with the first member; and pressure contact surfaces provided between the pin members and the first member being brought into contact with each other by the spring.

Abstract: According to an aspect of the present invention, a hinge device includes: a shaft part having a protruding part; and a bearing part having an insert hole into which the protruding part is inserted. A first plane part is formed on an outer peripheral surface of the protruding part so as to extend in an axial direction thereof. A second plane part is formed on an inner peripheral surface of the insert hole so as to extend in an axial direction thereof. A diameter of a circumscribed circle defined on an sectional outer periphery of the protruding part in the axial direction thereof is larger than a diameter of an inscribed circle defined on a sectional inner periphery of the insert hole in the axial direction thereof. And, at least one of the protruding part and the insert hole has an elasticity.

Abstract: The present invention provides a free stop hinge which can be stopped at any angle, the hinge having a structure in which a pressing force by means for pressing can be set with little variation and can be adjusted easily. The free stop hinge of the present invention connects an opening and closing member to a main body portion so that the opening and closing member can be opened and closed with respect to the main body portion and can be stopped at an arbitrary opening angle, which includes a hinge base and a hinge arm rotatably connected to the hinge base through an intermediation of a support shaft. The hinge base and the hinge arm are provided with bearing plates having shaft holes, respectively. Between the bearing plates, a friction plate having a shaft hole is disposed and the hinge arm is supported by a support shaft so as to be rotatable with respect to the hinge base.
