Abstract: A latch device includes a housing; a sliding body including a striking portion and a cam groove, and disposed relative to the housing so as to be capable of advancing and retracting; a spring member urging the sliding body in a direction protruding from the housing; an engaging body rotatably supported relative to the sliding body, and including a claw portion on an end thereof; and a pin member moving in such a way as to trace the cam groove. The engaging body can move between a locking position wherein the claw portion is protruded to a striking portion side, and locks the engaged/disengaged member, and a locking release position wherein the claw portion is retracted from the striking portion side. When the sliding body is pressed and the sliding body moves against an urging force of the spring member, the sliding body is retained in a position after a movement thereof through the cam groove and the pin member, and the engaging body moves from the locking release position to the locking position.

Abstract: A side rock device attaches a first member to a second member to be openable. The side rock device includes a pair of lock arms, a housing which holds the lock arms movably, a slider defining inclining holes which engage with the lock arms and urge the lock arms to protrude and retract, the slider disposed in the housing, and an elastic member which elastically urges the slider toward a predetermined direction. When the slider is operated against an elastic urging force of the elastic member, the lock arms are retracted.

Abstract: A portable electronic information device for performing information processing, data communication or the like. In the device, a slot is housed within a longitudinal rectangular housing recess formed at the rear portion of a lower wall of a device body so as to be able to be ejected therefrom and buried therein. A spring is provided within the housing recess so as to urge the slot outward. A locking unit is provided for locking the slot within the housing recess against the urging force of the spring. A guide frame is pivotally attached to the front portion of the lower wall of the device body so as to be erectable therefrom. A card-shaped information medium is attached through a through-hole of the erected guide frame to the slot which protrudes outside from the housing recess.

Abstract: An improved doorstop provides increased safety along with the simplified operation over previous doorstops. The doorstop is adapted to be mounted directly to the door in close proximity to an immovable surface such as the floor or a door channel. The device includes a frictional contact member which is leveraged from a first position away from the immovable surface to a second position in frictional contact with the surface. The improved doorstop is useful on sliding doors as well as hinged doors.

Abstract: A bolt lock for locking a sliding member having an aperture therein to a stationary member having an aperture therein includes a body adapted for mounting to the sliding member and the body including a guide in registry with the aperture of the sliding member. The bolt lock also includes a bolt having one end inserted through the guide for movement between a locked position of engagement in the aperture in the stationary member and an unlocked position of disengagement with the aperture in the stationary member, and a handle connected to the other end of the bolt with the handle engaging the body to lock the bolt in the locked position.

Abstract: A benthic dredge has a hollow body provided with closures at its upper and lower ends which are movable between open and closed positions. The closure at the lower end of the body is in the form of clamshell jaws which are pivotable about an axis located between the upper and lower ends of the body. Movements of the jaws are controlled by vertically reciprocable operating members and a force transmitting toggle linkage. No part of the linkage extends at any time beyond the confines of the body and the linkage is of such construction as to be capable of applying substantial closing force on the jaws as they approach their closed position.
