Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a detachable handle device used for transporting equipment such as a cassette tape recorder with radio reception, a stereo component, and the like.

BACKGROUND ART Conventionally, when a radio receiver has a detachable handle on a device such as a cassette tape recorder, as shown in FIG. Bearing parts 4a are provided on both sides, and a lock part 8b is provided at one end of a lock fitting 8 through which a support shaft 5 held by the bearing part 4a is inserted. A lock part 8b is hung in the hole 2a, a button 6 for releasing the lock and a return spring 7 are provided on the lock fitting 8, and a cover 9 is provided with a presser foot 9a to prevent the support shaft 5 from falling off using screws 10. It was configured to be fixed to a mounting boss 4b of the handle arm 4.

Problems to be solved by the invention However, in a handle device with such a configuration, the number of parts is large, material costs and assembly man-hours are high, and jigs and tools such as a screwdriver are required for assembly. Since the button 6 for unlocking is located at the top, there is a high possibility that the button 6 will be accidentally touched or hit against other objects while transporting the device, and there is a high possibility that the device will be damaged due to the heavy device body 1, speaker box 12, etc. There is a risk of injury if the button 6 falls, and since the rotation length of the button 6 cannot be made large, it rotates diagonally upward, which, together with the inability to reduce the amount of operation, leads to a worsening of the operating feel. There was a problem.

In addition, with the aim of reducing the number of parts, the cover 9 is eliminated, and in order to prevent the support shaft 5 from falling off, the bearing portion 4a is made into a through hole, and the support shaft 5 is used as a bolt, and after the support shaft 5 is inserted from the outside of the handle arm 4, it is fixed with a nut. Although such a structure has been devised, new problems such as loosening of the nut and exposure of the bolt/nut, resulting in an unsatisfactory appearance, have arisen, and this is not desirable.

Means for Solving the Problems The handle device of the present invention has a structure in which a return spring is sandwiched between a button and a lock fitting, and the support shaft is prevented from falling off by being fitted into a molded spring integrally formed with the button. It is something.

Function The handle device of the present invention prevents the support shaft passing through the lock fitting from falling off by utilizing the engagement of the molded spring provided in the button with the groove provided in the support shaft. This eliminates the need for separate parts such as a nut, and the structure in which the return spring is inserted between the button and the locking metal fitting allows the locking metal fitting to have an end support structure, and the release button can be placed below. This has the advantage that the operating stroke can be reduced.

Embodiment Hereinafter, a handle device according to an embodiment of the present invention will be described with reference to the drawings.

An embodiment of the present invention is shown in FIGS. 1 and 2.

In FIGS. 1 and 2, a connecting fitting 2 is attached to the device body 1 with connecting screws 3, and at the same time, other objects such as a speaker box 12 are hooked onto the connecting fitting 2. On the other hand, the handle arm 4 fixed to the handle bar 11 with a screw 10 has a through hole 4a into which the support shaft 5 can be inserted through the left and right wall surfaces.
A pin 4b protruding from the center of the inner surface, a button hole 4c into which the button portion 6g of the button 6 is inserted, a spring hook 4d protruding downward in a hook shape, etc. are provided. A groove 5a is cut in the center of the support shaft 5, and both ends of the shaft are chamfered. Next, the button 6 includes a shaft seat 6a that receives the support shaft 5 at one end, a molded spring 6b having spring properties that can be engaged with the groove 5a, two positioning pins 6c implanted near the molded spring 6b, and a pin. 4b is inserted through the elongated hole 6d,
Two ribs 6e extending downward at the same height as the seat surface of the positioning pin 6c, and a hook-shaped claw 6 protruding from the bottom end.
It has f. Also, a return spring 7 made of plate material
has a through hole 7a that is inserted through the positioning pin 6c, a seat surface 7b that rests on the rib 6e, and an ear portion 7c that is bent to hang on the spring hook 4d. Further, the lock fitting 8 has a bent portion at its upper end, a bearing portion 8a having a through hole through which the support shaft 5 can be inserted, a button fixing hole 8b into which the claw 6f is engaged, and a cut-and-raised piece 2a of the connecting fitting 2. It has a matching lock hole 8c.

The assembly order of the handle arm 4 of the handle device having the above configuration will be described. After inserting the through hole 7a of the return spring 7 into the positioning pin 6c of the button 6 and hooking the button fixing hole 8b of the lock fitting 8 onto the claw 6f, the handle arm 4
When the ear part 7c of the return spring 7 is hung on the spring hook 4d and the support shaft 5 is press-fitted from the side surface of the through hole 4a, the support shaft 5 passes through the bearing part 8a and the shaft seat 6a, and the molded spring 6b engages with the groove 5a, the support shaft 5 will no longer fall off. By chamfering or rounding the inner surfaces of the holes of the support shaft 5, molded spring 6b, and bearing portion 8a, or by appropriately setting the spring pressure of the molded spring 6b, the work of press-fitting the support shaft 5 can be carried out extremely easily. Since the molded spring 6b has the function of simply preventing the axial movement of the support shaft 5, the spring pressure,
There are few problems with strength, and integral resin molding is sufficient. Further, the pin 4b is automatically inserted into the elongated hole 6b during assembly, and serves to prevent the button 6 from wobbling from side to side. This is the inner dimension of the through hole 4a, and the bearing part 8a.
The same effect can be obtained by narrowing the gaps in the bending dimension and the width of the shaft seat 6a.

Since the return spring 7 has the seat surface 7b sandwiched between the rib 6e and the lock fitting 8, only both ends can be bent. In addition, the return spring 7 is dimensioned so that it is deflected when the ear portion 7c is hung on the spring hook 4d, so that the locking metal fitting 8 is secured in the assembled state.
is always biased outward.

When the handle assembled with the above structure is inserted from above the device, the locking fitting 8 rotates and the locking hole 8c engages with the cut-and-raised piece 2a, making it possible to transport the device. When removing the handle, just lift the handle while pressing the button part 6g of the button 6. At this time, the amount of button operation depends on the positional relationship of the support shaft 5, the button 6, and the cut and raised piece 2a, so the optimum value can be obtained by arbitrarily setting these. In addition, the buttons can be placed considerably lower, reducing the risk of the device falling due to hands or other objects touching the buttons during transportation. There is little discomfort on the top.
In terms of appearance, the design has a sense of stability because the button is located at the bottom, and the spindle is only slightly visible beyond the through hole, and the spring hook is on the bottom so it is not noticeable and is very good. Furthermore, if a locking rib 4e is installed on the upper part of the inner surface of the handle arm 4, it is possible to prevent the return spring 7 from becoming sagging due to excessive rotation of the lock fitting 8.

Note that in order to disassemble the handle arm portion, it is sufficient to poke the support shaft 5 from the side with a rod-like object.

Effects of the invention As described above, the handle attaching/detaching device of the present invention is easy to assemble and disassemble by having a structure in which a support shaft with a groove in the center is inserted through the handle arm and the molded spring of the button is engaged with the groove. No jigs or tools are required, it is reliably prevented from falling off, and has a good appearance. In addition, by integrally molding the seat of the support shaft that faces the molded spring with the lock release button, the number of parts is reduced and assembly becomes easier.Furthermore, one end of the return spring is sandwiched between the button and the locking metal fitting to secure it. However, by having the other end hung on the lower end of the handle arm, and by setting the rotational fulcrum of the locking metal fitting at the upper end, the button can be positioned closer to the lower end, which is advantageous for safety, and also has a beautiful appearance and a comfortable button operation. It has a good stroke and is extremely advantageous in practice.
