The objective of the present invention is to provide an articulated fitting having a structure in which a lock pin and a plate do not come into contact with one another when a leg-side bracket is moved in a folding direction or an opening direction, thereby preventing wear of the lock pin and preventing leg backlash for an extended period of time. An articulated fitting 1 is characterized in that: a roller 800 is provided on a side plate 220 of a leg bracket 200; the roller 800 comes into contact with a side peripheral surface of an arm portion 430 of a lever 400; in an open-leg state, the roller 800 engages with a recessed portion formed adjacent to a claw portion 433 of the arm portion 430; and in a closed-leg state, the roller 800 comes into contact with a side peripheral curved portion of the arm portion 430.

The purpose of the present invention is to provide a joint fitting equipped with a mechanism for locking a lever that switches between a locked state and an unlocked state while maintaining the excellent operability of a lock mechanism realized by a horizontal rod, a notch part, and an elongated hole in a conventional joint fitting for a table, the joint fitting being capable of locking the lever when a leg is opened/closed. This joint fitting is characterized by comprising: a top plate base that is attached to the lower surface of a top plate; a leg base that is attached to a leg body which supports the top plate; a hinge pin that pivotally supports the top plate base and the leg base such that the top plate base and the leg base are swingable; a lock pin that is inserted into an elongated hole provided in the top plate base and that is capable of locking the top plate base and the leg base; a lever for operating the lock pin; a lever pin that is inserted into the top plate base and that pivotally supports the lever such that the lever is swingable; and a spring with two opposing ends that are wound onto the lock pin and the hinge pin. The joint fitting is also characterized in that: the lock pin is inserted into a lock pin hole provided in the lever, and when the top plate and the leg are in an open leg state and in a locked state, the lock pin is locked to a first notch part provided in the leg base; when the top plate and the leg are in a closed leg state and in a locked state, the lock pin is locked to a second notch part provided in the leg base; and when in an unlocked state, a trigger that is supported by a bracket attached to the top plate base and that moves linearly causes the lever to be in a locked state.

The purpose of the present invention is to provide a long leg fixing device that further enhances the conventional effect of holding a bottom surface and a side surface of a connecting crosspiece and reducing wobbling when legs are opened, makes it possible to retain an open-leg state by engaging components on the side surface of the connecting crosspiece without depending on elastic force of a spring, and, simultaneously, facilitates an operation to release a closed-leg state, and ensures sufficient strength even when the connecting crosspiece is long.　This long leg fixing device is for use in a table that stands on four long legs and that has a structure in which two of the long legs are connected by a crosspiece part, and the two long legs fitted in a swingable manner to the table by a hinge move together to open and close the legs. The long leg fixing device is characterized by comprising: a base 3 that is fixed to the table; an arm 5 that swings around an arm pin 4 inserted through the base 3; an adjust screw 6 that is provided in an intermediate portion of the arm 5 and rotates around a longitudinal direction of the arm 5 as an axis; a touch pad 7 that is threadedly engaged with the adjust screw 6 and is linearly moved in the longitudinal direction of the arm 5 by the rotation of the adjust screw 6; a latch spring 8 attached to the inside of the touch pad 7; and a latch 9 that is biased by the latch spring 8, and linearly moves in the longitudinal direction of the arm 5. The long leg fixing device is further characterized in that the latch 9 is biased by the latch spring 8 to lock with a catch plate 2 fitted to the crosspiece part, and that the touch pad 7 comes into contact with the catch plate 2.

The objective of the present invention is to provide a long leg fixing device which, while maintaining the conventional effect of suppressing unsteadiness when legs are open by supporting a bottom surface and a side surface of a linking crosspiece, maintains the open-leg state by means of engagement with a component on the side surface of the linking crosspiece, without relying on the elastic force of a spring, and at the same time facilitating an operation to release a closed-leg state. This long leg fixing device is for use in a table which is erected using four long legs and which has a structure in which two of the long legs are linked by means of a crossbeam portion, and said two long legs, fitted to the the table in such a way as to be capable of pivoting by means of a hinge, move together to open and close the legs, wherein the long leg fixing device is provided with a base 12 fixed to the table 2, a lever 11 which swings about an arm pin 13 inserted through the base 12, and an arm 8 and a latch 9 which move in conjunction with the swinging of the lever 11, and in the open-leg state of the long legs 3, the arm 8 and the latch 9 grip a seat portion 7 fitted to the crossbeam portion 4.

The purpose of the present invention is to provide a device which makes it possible to fix a leg body to a top plate while maintaining an open-leg state of the leg body, by means of abutment between a cam that pivots in parallel with the leg body and a member corresponding to the follower of the cam. A leg body fixing device 1 of the present invention is provided with: a top plate bracket 100; a leg bracket 200; a hinge shaft 300 which supports the leg bracket 200 pivotally in a hinged manner with respect to the top plate bracket 100; and a lever 400 which pivots in parallel with the leg bracket 200. The lever 400 includes a shaft portion 410 different from the hinge shaft 300, and an operating portion 420 and a cam portion 430 which oppose each other across the shaft portion 410. The cam portion 430 includes a small curvature surface 433. The leg bracket 200 includes a seat portion 230 having a curved receiving surface 231 with a curvature corresponding to that of the small curvature surface 433. When the small curvature surface 433 abuts against the curved receiving surface 231, the cam portion 430 maintains a stationary state and blocks pivoting in a direction in which the leg bracket 200 is closed.
