  • Publication number: 20200308881
    Abstract: A lock device includes a base member fixed on an opening/closing member, an operation member rotatably supported on the base member, and a rod configured to move forward and backward to be engaged with and disengaged from a locked portion of the fixed member in response to operation of the operation member, The operation member includes a pivot portion and a transmission portion. The base member includes a first attachment portion and a second attachment portion. When the transmission portion presses an inclined surface of the rod and thus causes the rod to move backward, the first attachment portion abuts against the rod, thereby limiting movement of the rod in the direction intersecting with the forward and backward movement direction of the rod.

  • Patent number: 10612279
    Abstract: A lock device for holding an openable and closable member in a closed state. The lock device includes a base member, an operation member, a rod, and a cylinder lock. The cylinder lock has a protruding portion biased to protrude radially outwards to be engaged with an engaging portion formed on a rear side of a cylinder accommodating portion. The rod has a distal end portion configured to move out of a through hole formed in the openable and closable member to be engaged with a locking portion on a fixed member over a predetermined length with the openable and closable member left in a locked state, and a pushing portion enables a release of an engagement with the engaging portion when the rod moves in a receding direction to abut with the protruding portion, causing the protruding portion to recede against a biasing force.

  • Patent number: 10570655
    Abstract: A stopper device includes: a stopper that has an abutting part located at a distal end of a tubular part in the axial direction, and a through-hole penetrating through the abutting part and communicating with the inside of the tubular part; and a screw that has a flange-shaped screw head accommodated in the tubular part, and a shaft projecting toward a proximal end side of the tubular part in the axial direction. The tubular part has a first restricting part that restricts movement of the stopper toward the distal end in the axial direction by being engaged with the screw head. The position of the stopper in the axial direction is changed by inserting a tool in the tubular part through the through-hole and rotating the screw.
