Abstract:
A catcher 2 includes a catcher stopper 21, a holder 22 for a striker 1, and a biasing member 23 for the catcher stopper and the holder. When the catcher stopper 21 is projected by the biasing member 23, the holder 22 is set in a forward position and in a non-holding state, and when the holder 22 is set in a backward position and in a holding state, the catcher stopper 21 is withdrawn. The recess Mb has an engageable hole 402 formed therein for engagement with the catcher stopper 21, and a force is stored in the biasing member 3 when the catcher 2 is set in a reference position where the catcher stopper 21 is brought into engagement with the engageable hole 402. The sticker 1 enters the holder 22 of the catcher 2 when the catcher is set in the reference position since the movable member M is moved forward to a self-propelled movement start position.
Abstract:
A runner 5 including a striker 51 in a lower portion; a catcher 6 corresponding to the striker 51 and engaging a movable body 1 in a reference position R; and an urging device 7 storing an urging force when the catcher 6 is in the reference position R, are provided. The catcher 6 in the reference position R captures the striker 51 of the runner 5 stopped and engaged with a rail 2 in a self-propelling start position SA of the movable body 1, and upon this capture, an engagement between the catcher 6 and the movable body 1 is released. At the same time, due to a backward movement of the movable body 1 from the stop position SA, the catcher 6 is positioned in the reference position R again, and releases the striker 51 of the runner 5. An engagement between the runner 5 and the rail 2 is subsequently released.
Abstract:
A movable member moved forward to a predetermined position can automatically move further forward. The mechanism includes first and second connecting members provided in the movable member and an immovable member. The second connecting member includes a catcher for catching the first connecting member and an urging device for urging the catcher. The catcher is arranged to be able to move or relatively move along a moving direction of the movable member, and held in a waiting position while receiving an urging force by the urging device toward a forward movement direction or backward movement direction of the movable member. When the movable member is moved to the predetermined position, the first connecting member is retained by the catcher of the second connecting member, and upon releasing of retention, the movable member is automatically moved forward to the stopped position by the urging force.
Abstract:
When releasing a connection between a second tube member and a first tube member, a ring member is moved, whereby an inclined surface of a bump part and an inclined surface of a bump part of a cam part slide, and a stopper rotates from a coupled position to an uncoupled position. Thus, a coupling between a leading end part of a claw part of the stopper on the second tube member, and a coupling surface of a coupling-accepting part on the first tube member is released. In connecting the first and second tube members, when the first tube member is pushed into the second tube member with the ring member in the locked position, the claw part of the stopper is elastically deformed, whereby the leading end part of the claw part rides past the coupling-accepting part, and couples to the coupling surface of the coupling-accepting part.
Abstract:
A catcher (2) comprises a catcher stopper (21), a holding body (22) for holding a striker body (1), and a biasing body (23) for them. When the catcher stopper (21) is projected by the biasing body (23), the holding body (22) is located at the forward position in a non-holding state. When the holding body (22) is located at the backward position in a holding state, the catcher stopper (21) is retracted. An engaging hole (402) for the catcher stopper (21) is formed in a recess (MB). A biasing force is stored in the biasing body (3) when the catcher (2) is located at the reference position where the catcher stopper (21) is engaged with the engaging hole (402). When the movable body (M) is moved forward to the self-propelling start position, the striker body (1) is advanced into the holding body (22) of the catcher (2) at the reference position.
