突起がばねによって弾性的に突没自在に設けられている
とともに、上記本体の上記扉の突起が設けられた側面と
対応する内側面には凹部が設けられている。A locking device is used for the main body and the door in order to securely maintain the closed state when the door is closed. In a conventional locking device, a protrusion is provided elastically by a spring on a side face of a free end side of the door so that the protrusion can be retracted by a spring, and an inner surface corresponding to a side face of the main body on which the protrusion of the door is provided. Is provided with a recess.

扉を開方向に回動させれば、上記突起と凹部との係合が
外れて保持状態が解除されるようになっている。Therefore, when the door is closed, the projection is elastically engaged with the recess and held in the closed state, and when the door is rotated in the opening direction, the projection is engaged with the recess. Is released and the holding state is released.

こともある。By the way, according to the locking device having the above structure,
In the door, since the projection is elastically engaged with the recess and only the closed state is maintained, if the careless external force acts on the door, the engagement between the projection and the recess is released. There was a case that the above door was opened. Especially when the furniture shakes due to an earthquake or the like and the luggage inside collapses toward the door,
The momentum may open the door and the luggage may be scattered outside.

いうことが生じる。It is possible to prevent the engagement between the projection and the concave portion from being disengaged by an unexpected external force by increasing the biasing force of the projection by the spring. However, if the urging force of the protrusion by the spring is increased, the protrusion does not easily engage with and disengage from the recess when the door is opened and closed, so that the door cannot be opened and closed smoothly.

A locking device for holding the door in a non-rotatable state and a releasing device for releasing the holding state of the door by the locking device, wherein the locking device includes a receiving member provided in the main body and the door. The receiving member is composed of a locking shaft that is slidable in the axial direction, and the receiving member is a plate-shaped body having a predetermined thickness, an annular groove formed inside the plate-shaped body, and a tip of the plate. An insertion groove formed so as to open at one end face of the strip and open at one side face thereof while intersecting with the annular groove, and a rear end thereof located substantially in the radial center of the annular groove; Relief formed inside the body on the rear end side of the insertion groove and in communication with the annular groove. A plurality of balls that are provided rotatably over substantially the entire annular groove and that project into the insertion groove at a location that intersects with the middle portion of the insertion groove, and the door that is provided in the escape portion. The locking shaft is inserted from the tip of the insertion groove by rotating in a closing direction and elastically deforms when the ball protruding in the middle of the insertion groove is pressed to the escape portion. Allowing the balls located opposite to each other to enter the escape portion, and when the locking shaft is inserted to the rear end of the insertion groove, the ball that has entered the escape portion by the restoring force into the annular groove. The releasing device is composed of a spring for pushing back, and the releasing device has a case provided on the door and an operation of slidably provided on the case to slide the locking shaft in the axial direction to lock the locking shaft. Pull out the tip of the shaft from the insertion groove of the above receiving tool. In furniture, characterized in that and an operating body which.

Since the connecting rod 44 slides in the direction of the arrow C by the frame 58, the locking shaft 12 slides in the direction in which the tip portion protruding from the upper and lower end surfaces of the door 3 is retracted. The sliders 54 of the pair of left and right releasing devices 5 are connected by a rod-shaped member 65 having a spring portion 64 in the middle thereof to urge the slider 54 in the restoring direction. Since the slider 54 is provided with the spring 60 that biases the slider 54 in the restoring direction, the rod-shaped member 65 may be omitted.

The front ends of the four locking shafts 12 projecting from the upper and lower end surfaces of the door 3 are located at the rear end of the insertion groove 31 of the receiving member 11, that is, at the center of the annular groove 24. When the four locking shafts 12 are engaged with the insertion groove 31 and the door 3 is rotated in either the left or right direction, the locking shaft 12 projects into the middle of the insertion groove 31. Since the ball 35 prevents the insertion groove 31 from sliding toward the tip side, the door 3 cannot be rotated in the opening direction.

から外れる。When the door 3 is opened with the right side as a fulcrum as shown in FIG. 9, the slider 54 of the releasing device 5 provided on the left side is pulled. As a result, the pair of locking shafts 12 provided at the upper and lower end portions on the left side of the door 3 are slid in the direction in which they are retracted into the door 3 via the arm 58 and the connecting rod 44, so that the tips thereof.

い。The door 3 has a predetermined thickness, and in the closed state, the peripheral portion of its inner surface is joined to the front end surface of the main body 1 with a predetermined width dimension. Therefore, when the door 3 is opened with the right end portion as a fulcrum, the inner surface of the right end portion in the width direction hits the front end surface of the main body 2 and cannot be opened smoothly.

る。However, the respective locking shafts 12 are inserted into the long holes 42 of the holding member 41 provided at the four inner corners of the door 3,
The spring 43 presses the elongated hole 42 in one direction. Therefore, when the inner surface of the end portion of the door 3 hits the front end surface of the main body 2 when the door 3 is opened, the contact force causes the spring 43 to be compressed. As indicated by the arrow in a), slide along the locking shaft 12 in the direction away from the front end surface of the main body 2. Therefore, in the closed state, even if the inner surface of the door 3 is joined to the front surface of the main body 2, the door 3 can be smoothly opened and closed.

A pair of balls 35 located on both sides of the intermediate portion protrudes to reduce the width dimension of the insertion groove 31. When the tip of the locking shaft 12 passes therethrough, the ball 35 is pressed in the left-right direction of the annular groove 24 as shown by the arrow in FIG.
