Description

[Detailed Description of the Invention] This invention relates to a mounting device for a bush latch used for opening and closing a door body, a lid body, etc. of a box body.

In recent years, this type of bush latch has been widely used to hold the lids of racks of audio equipment open and closed.

However, many of these types of bush latches have mounting parts protruding from both sides of the case body, and these mounting parts are attached to the surface of the board that makes up the rack, which spoils the appearance of the rack. Another drawback is that the internal space cannot be used effectively.

As a means to solve this problem, a mounting plate is integrally provided from the tip of the case body in a radial direction, while the case body is housed in a storage hole provided in a board of a box body such as a rack. It is possible to fix the board to the board,
If the case body is made up of a sheath body that is divided into two halves in the axial direction, if a mounting plate is provided protruding from the tip, the strength of the joint between the mounting plate and the sheath body will be weakened.
When attaching the mounting plate to a board constituting the upper plate of the rack, there arises the problem that the board itself has no space in the vertical direction for fixing the mounting plate in addition to the mounting holes.

This idea solves this problem, and even if the case body of the buttshut latch is split into two vertically in the axial direction, the buttshut latch can be securely fixed into the storage hole provided in the board on the box side. However, we do not provide any mounting equipment.

An embodiment of this invention will be described below in detail based on the drawings. Reference numeral 1 is a case body of a bush latch, and the case body 1 is made of synthetic resin such as polypropylene and has an approximately round bar shape. At the tip thereof, there are formed flanges 1d and ld with flat portions 1c and 1c at the upper and lower portions, and an actuating body 2 protruding from the tip is engaged inside by the first pressing action. A known bush latch mechanism is incorporated therein, which is configured to lock the handle and push it out with the next pressing action.

There are no particular limitations on the external shape of the main body 1, but in short, the shape of the mounting hole described later is easy to drill, and when the case main body 1 is inserted into the mounting hole, the case main body 1 can be mounted without much play. It is desirable that it be shaped so that it can be inserted easily.

To explain this case body 1 in more detail, it is divided into two parts in the axial direction, an upper sheath body 1a and a lower sheath body 1b.
From the thick part of the upper sheath body 1a, the protrusion 3,
3... is provided in a protruding manner, and the thick part of the other lower sheath body 1b is provided with a mounting hole 4... through which this protrusion is inserted.
The upper sheath body 1a and the lower sheath body 1b are placed one on top of the other, the protrusion 3 is inserted into the mounting hole 4, and the head of the protrusion 3 is melted and crushed so that they are superimposed and fixed so that they form a cylindrical body. Ru.

The bush latch mechanism has a compression coil spring 5 acting on an actuating body 2 that is slidably housed inside the case body 1 to constantly move and energize the actuating body 2 forward. A torsion coil spring 7 is applied to rotatably pivot the actuator, and a locking pin 8 protruding from the upper sheath body 1a is intermittently locked through an elongated hole 2b provided in the actuating body 1. The actuating body 1 is configured so as to be engaged with the piece 6.
A magnetic body 2a is attached to the tip of the upper sheath body 1a, and a magnet 9 is attached to the side of the upper sheath body 1a in contact with the magnetic body 2a so as to be able to move back and forth slightly, and its front end protrudes to the outside.

On the other hand, the board 10 constituting the upper plate of the box has storage holes 1.
1 is provided, and the case main body 1 is stored in this storage hole 11, and the tip part protruding from the board 10 is covered with a mounting plate 12, and is fixed to the board 10 with screws 12b, 12b. ing.

Since the mounting plate 12 is provided with an insertion hole 12a that is slightly smaller than the outer diameter of the tip of the case body 1, the actuating body 2 and the magnet 9 can be inserted through it, but the case body 1 cannot be pulled out forward. mounting plate 1.
2 is a flat portion 13 a provided at the tip of the case body 1;
3a, which prevents the case body 1 from rotating.

Therefore, in this state, when the lid 13 is pushed in the closing direction, the suction piece 14 attached to the lid 13 comes into contact with the tip of the actuating body 2 as it approaches closing.

When this is further pushed, the actuating body 2 moves backward against the bias of the spring 5, and the locking pin 8 slides on the inclined tip of the locking piece 6, causing it to rotate against the bias of the spring 7. Finally, the locking portion 15a of the zigzag locking groove 15 is locked, so the actuating body 2 stops at this position and is not pushed out by the bias of the spring 5.

At the same time, the magnetic body 2a fixed to the tip of the actuating body 2 comes into contact with the magnet 9 and is magnetized, and the attraction piece 14 is attracted by the magnetic force of the magnetic body 2a and the magnetic force of the magnet 9. remains closed and stable.

At this time, the rear end of the main body 1 is in contact with the terminal end of the storage hole 11, so even if the main body 1 receives a pressing force through the operating body 2 due to the lid 13 being closed, it will not move backward. , so-called rattling does not occur.

The same effect can also be achieved by configuring the flanges 1d and ld provided at the distal end of the case body 1 to be hooked on the distal end of the storage hole 11.

Next, when the lid body 13 is pushed again in the closing direction, the head of the locking pin 8 slightly lifts a part of the locking groove 15 of the locking piece 6 which has been rotated by the force applied by the spring 7.
5b, the locking state between the locking pin 8 and the locking piece 6 is released.

Then, the actuating body 2 is pushed forward slightly by the force of the spring 5, and the force pushes the lid body 13 away from you, so even if the magnetic force remains in the magnetic body 2a, the force causes The state of magnetic attraction between the attraction piece 14 and the magnetic body 2a is automatically released.

After that, by placing your hand on the open end of the lid 13 and pulling it toward you, you can open and close the lid 13 without needing any handholds.

Then, when the magnetic attraction between the magnetic body 2a or the magnet 9 and the attraction piece 14 is released, the case body 1 is pulled toward the front via the actuating body 2 or the magnet 9, but this is caused by the attachment plate 1
2 prevents the case body from slipping out toward the front.

As explained in detail above, according to this invention, even if the case body is divided into two halves in the axial direction, the case body can be securely housed without protruding outward, rattling, or rotating. Since it can be stored and fixed in the hole, even if it is attached to the board before the box is assembled, it will not get in the way during packaging, and there is no risk of it being destroyed during transportation, and it can be attached to the board before the box is assembled. Since the case body does not protrude into the box body unlike other cases, the space inside the box body can be used effectively, and the appearance can also be extremely sleek.

In addition, if the case body is split into two parts in the axial direction, the mounting plate will inevitably be weakened if the mounting plate is integrated at the tip, and if this is to be prevented, the mounting plate will have to be thicker. It is unavoidable that a large gap will occur between the lid and the board, but this idea separates the case body from the mounting plate and prevents the case body from rotating relative to the mounting plate. Since this mounting plate is configured to hold down the case body stored in the storage hole from the front, the longitudinal movement force applied to the case body via the operating body and magnet when opening and closing the lid is absorbed by the case body. This is prevented by the rear end contacting the storage hole, by the collar catching on the entrance of the storage hole, or by the mounting plate attached to the front of the case body, etc. It is possible to achieve the effect that the case body does not play in the longitudinal direction or come out.
