Abstract
A mechanism for keeping a lock device released comprises a through-hole which is defined through a side surface of an intermediate block member having a lock device and which externally communicates, a hexagon wrench which is inserted externally through the through-hole and which is connected to a lock plate, and a plate spring which fastens the hexagon wrench with the lock being released by moving the lock plate upwardly with the hexagon wrench.
Claims14
A mechanism for keeping a lock device released from a movable member, said mechanism comprising:
- a casing which accommodates said lock device and which has a manual operation hole defined in a side surface of said casing;
- a piston accommodated in a chamber defined in said casing, said piston being connected to said movable member for reciprocally moving said movable member in accordance with supply of a fluid under pressure to said chamber:
- a connecting member which is inserted externally through said manual operation hole and which is connected to a lock member of said lock device;
- and
- a fastening member which enables displacement of said lock member by said connecting member for releasing said lock device from said movable member and which fastens said connecting member with said lock device being kept released from said movable member.
A mechanism for keeping a lock device released from a movable member, said mechanism comprising:
- a casing which accommodates said look device and which has an opening defined in a side surface of said casing;
- a piston accommodated in a chamber defined in said casing, said piston being connected to said movable member for reciprocally moving said movable member in accordance with supply of a fluid under pressure to said chamber;
- and
- a tilting member which is disposed in said opening and which pivots by a predetermined angle about a support point of a pin also disposed in said opening, so that a lock member of said lock device can be displaced for keeping said lock device released from said movable member.
A mechanism for keeping a lock device released from a movable member, said mechanism comprising:
- a casing which accommodates said lock device and which has a manual operation hole defined in a side surface of said casing;
- a connecting member which is inserted externally through said manual operation hole and which is connected to a lock member of said lock device;
- and
- a fastening member which enables displacement of said lock member by said connecting member for releasing said lock device from said movable member and which fastens said connecting member with said lock device being kept released from said movable member,
- wherein said fastening member is composed of a plate spring having a fastening section for fastening said connecting member, said plate spring having a composite circular configuration being a combination of a first curved section and a second curved section, said first curved section having a substantially horizontal spacing distance larger than a diameter of said connecting member and said second curved section having a substantially horizontal spacing distance corresponding to said diameter of said connecting member.
