The details will be explained next.

According to the drawings, in Figs. 1 to 4, numeral 1 is a rack for audio equipment, which is an example of a box, and numeral 2 is a rack on one side of the rack 1, so as to cover, for example, the front surface of the record storage part. This is a glass door that is an example of an opening/closing body that is attached to a door so that it can be opened and closed. An opening/closing holding device 3 is provided between the glass door 2 and the rack 1 and is fixedly embedded in the top plate 1a of the rack 1.

This opening/closing holding device 3 includes a case portion 4 that is embedded and fixed in the top plate 1a of the rack 1 with the opening facing downward, and a case portion 4 that is twisted between itself and the case portion 4. Claw portions 6a and 6b, which are an example of a pair of opening/closing body holding portions, are provided protruding from one side in the radial direction, and are pivoted while being urged to rotate clockwise by resiliently installing a spring 5. Operating body 6 consisting of
and a push latch mechanism A provided between the actuating body 6 and the case portion 4, and the push latch mechanism A includes a heart-shaped and spherical endless cam groove 6c carved on the outer periphery of the actuating body 6. , and a cam pin 8 whose tip end is fitted into the cam groove 6c, and which is attached to the case part 6 so as to be able to slide and swing while being biased toward the endless groove 6c by a compression coil spring 7. .

Next, the operation will be explained. When the glass door 2 is open, the actuating body 6 is rotated clockwise, so as shown by the imaginary line in FIG. The claw portion 6a provided at 6 is in contact with one side of the inner wall of the case portion 4, and the cam pin 8 is located at the position A of the endless cam groove 6c as shown in FIG.

When the glass door 2 is closed, the upper end of the glass door 2 is connected to the other claw part 6 provided opposite to the claw part 6a.
Since the actuating body 6 comes into contact with and pushes b, the actuating body 6 rotates counterclockwise against the elasticity of the spring 5. At this time, as shown in FIG. 4, the cam pin 8 advances along the endless cam groove 6c in the direction of the arrow a from the position A to the position B, and the actuating body 6 stops at this position. Then, when you release your hand from the glass door 2, the actuating body 6, which is rotated and energized clockwise, returns a little to its original position, and the cam pin 8 swings its head slightly and moves in the direction of arrow b, causing the endless cam groove 6c to move forward. It stops by being locked at point C.

This state is shown by the solid line in FIG. 2, and the glass door 2 is locked and held between the claws 6a and 6b without using magnetic attraction means as in the prior art, and the door is in a closed state. keep it.

Next, when opening the glass door 2, when you push it again in the closing direction and release your hand, the actuating body 6 will cause the cam pin 8 to swing slightly inside the endless cam groove 6c, as shown in FIG. The cam pin 8 moves in the direction of arrow d, rotates counterclockwise until it reaches the position of Push forward. Therefore, all that is left to do is to put your hand on the end of the glass door 2 and pull it toward you to fully open it without using the handle.

It differs from the previous embodiment in that it is composed of a and 9b. The arms 9a, 9b are pivotally supported by a common support shaft 10, and both are biased to rotate clockwise by a torsion coil spring 5 elastically installed between them and the case portion 4, and project from each other. It has claw portions 9c and 9d which are examples of opening/closing holding portions, and a slight gap is provided on the opposing surfaces of each of the claw portions 9c and 9d.

When carried out in this way, when the glass door 2 is opened, a gap a is created on the right side between the arms 9a and 9b as shown in FIG. 5, and when the glass door 2 is closed, a gap a is created as shown in FIG. , arms 9a, 9b
A gap b is generated in the lower part of the door and functions to pinch the glass door 2, so that it is possible to adjust the error in the closing position due to the misalignment of the mounting position of the glass door 2 or the case part 4, and Since the end portion of the glass door 2 is sandwiched between the pair of claw portions 9c and 9d, there is an advantage that no backlash occurs due to thickness error of the glass door 2.

Note that the push latch mechanism B in this embodiment
The configuration is the same as that of the previous embodiment. The other functions are also the same as those of the previous embodiment, so their explanation will be omitted.

FIG. 8 shows still another embodiment, and according to the drawing, the lid body 11, which is an example of a top-opening type opening/closing body, only needs to be supported when the lid is closed. By changing the position to the front plate 12a of the cabinet, only one claw portion 13a, which is an example of an opening/closing body holding portion of the operating body 13, is required. The structure of the push latch mechanism C is the same as that of the first embodiment, so a description thereof will be omitted.

When carried out in this manner, it is possible to utilize the present invention as an opening/closing holding device for the top-opening type lid body 11.

FIG. 9 shows still another embodiment, and according to the drawing, there is only one claw part 14a protruding from the actuating body 14, a magnet 15 is fixed to this claw part 14a, and a magnet 15 is fixed to the glass door 2 side. A magnetic body 16 is attached.

When carried out in this way, the glass door 2 is held by the magnet 15 by magnetic attraction when the door is closed, and when the door is opened, the glass door 2 that is slightly opened is held by the hand.
You can open it by pulling it towards you. However, this is a case where the glass door 2 is opened slowly, and if you push the closed glass door 2 in the closing direction and quickly release your hand, the glass door 2 will automatically open to the front due to the inertial force when it is opened. Pull magnet 1 by hand
There is no need to release the magnetic attraction between 5 and the magnetic body 16.

Note that the structure of the push latch mechanism D is the same as that of the first embodiment, so a description thereof will be omitted.

FIG. 10 shows another embodiment of the push latch mechanism. According to the drawing, the push latch mechanism E uses a ball bearing 18 pressed toward the endless cam groove 19a by the elasticity of the rubber plate 17 instead of the cam pin. There is.
