Description

[Detailed description of the invention] This invention relates to a handle attachment/detachment device, and its purpose is to provide a handle attachment/detachment device that allows easy attachment/detachment of the handle and allows for reliable attachment/detachment of the handle. be.

Recently, the dimensions of component-type cassette decks, tuners, amplifiers, etc. have been reduced so that they can be used indoors for stationary use, and can also be carried around when necessary.
So-called microcomponents are being supplied to the market.

Normally, these microcomponents are made so that the independently configured cassette deck, tuner, amplifier, etc. all have the same width and depth dimensions, so when carrying them, you can use a mounting plate to connect them to each other. They are connected together and hung by a handle, but when used indoors, the handle is not needed, so it is more convenient to use a removable handle.

However, even though microcomponents have been miniaturized, stacking three microcomponents adds up to a considerable amount of weight, and the handles for hanging them and their attachment/detachment parts must be made strong, and in particular, their locking must be secure. There must be.

Fig. 1 is an exploded view showing the component configuration of the handle attachment/detachment device according to the embodiment of this invention, and Fig. 2 is a sectional view showing its assembled state. A cavity 1a is formed in the center, and the length is approximately the same as the width of the microcomponent.

Reference numeral 2 denotes a handle joint, which is molded into a shield shape from a synthetic resin such as ABS, and has a coupling piece 2a protruding from one end thereof.

Reference numeral 3 denotes a reinforcing plate made of a steel plate, which has a U-shaped cross section and an inverted letter-like shape as a whole, and 4 is a locking plate made of a steel plate, which is rotatable and has a hook portion 4a at its lower end. has been done.

5 is a decorative board, which is a laminated resin board type product such as ABS, and 6
is a lock piece, which is molded from synthetic resin such as ABS, and is rotatable about pins 6a protruding on both sides as a fulcrum.

Further, 7 is a rotation shaft, and 8 is a torsion spring.

The structure of the handle attaching/detaching device of this embodiment is as described above.Next, the assembly method and the function of each part will be explained.

The reinforcing plate 3 has a through hole 3a, and the locking plate 4 has a through hole 4b.
are provided respectively, and by inserting the shaft 7 through the through holes 3a and 4b, they are coupled together, and further, by inserting the coil portion 8a of the torsion spring 8 through the shaft 7, the locking plate 4 is closed.
The reinforcing plate 3 is biased to rotate in the counterclockwise direction.

Next, insert the horizontal part 3b of the reinforcing plate 3 into the opening 2 of the bundle joint 2.
b protrudes outward along the connecting piece 2a, and the horizontal part 3b
and the protruding piece 2a and handle part 1. After being inserted into the hollow portion 1a of the bundle, the bundle joint 2 and the reinforcing plate 3 are connected to the handle portion 1 with screws 9, and the bundle joint 2 and reinforcing plate 3 are screwed together with screws 10.

In this case, the lock piece 6 is held on both sides by the upper opening 2C of the bundle joint 2, and is rotatable by bringing the pin 6a into contact with the protrusion 3C of the reinforcing plate.

After that, the decorative plate 5 is screwed to the outside of the locking plate 4 with the screws 11 to complete the assembly, and in this case, the decorative plate 5 closes the opening 2b of the bundle joint and improves the appearance of the bundle attachment/detachment part.

In the assembled state shown in FIG. 2, the locking plate 4 is prevented from rotating counterclockwise by the torsion spring 8, and the hook portion 4a is locked.
is inserted into the through hole 12a of the mounting plate 12 of the microcomponent (not shown), and furthermore, the upper end 4C
Since it is in contact with the stepped portion 6b of the lock piece 6, there is no fear that the hook portion 4a will come off even if a force is applied to open the lock plate 4 (to rotate it clockwise).

Further, a slightly raised bulge 6C is formed on both sides of the lock piece 6, and when this bulge 6C crosses the side wall of the opening 2C of the bundle joint, a moderating action is performed, and the lock piece 6 is constructed so that it does not easily open due to external impact or the like.

In addition, although only one side of the bundle attachment/detachment device is shown in FIGS. 1 and 2, components 2, 3, 4, 5.6, etc. other than the bundle handle 1 may also be provided on the opposite side. ing.

However, if the weight of the set suspended by the bundle is relatively light, the attachment/detachment device may be provided only at one end, and the other end may be constructed as a simple hook type.

Next, FIG. 3 shows a case where the lock piece 6 is rotated in the direction of arrow A in order to remove the bundle. In this case, as shown in FIG. By pushing the upper part of the bundle device in the direction of arrow B, the lock plate 4 rotates clockwise against the torsion spring 8, and the hook portion 4a comes out of the through hole 12a of the mounting plate, allowing the entire bundle device to be removed. Become.

As described above, the bundle attachment/detachment device according to this invention is easy to remove and remove, and in the installed state, the lock plate which is pressed to the locked position by the spring means is further locked by the lock piece, and the lock piece itself is also moderated. Since it is held in the locked position by the action, it has the advantage that the installed state is reliably maintained even when the set weight that is applied to the mounting plate is large and an external impact is applied.

Claims (1)

[Scope of utility model registration request] A locking member rotatably provided at the end of the handle and having a hook portion formed at one end; a spring means for biasing the locking member to rotate in a locking direction; and a spring means capable of contacting or retracting from the other end of the locking member. When the hook portion of the locking member is coupled to the suspended member, the locking member prevents rotation of the locking member,
The handle attachment/detachment device is configured such that the locking member can rotate against spring means when the locking member is rotationally displaced in the retracting direction.
