Abstract

(57) [Summary] [Purpose] To improve the handleability of the handle that can be stored and pulled out in a portable device such as a boombox, while improving its durability and improving its operational reliability.
In addition, the structure is simplified and the number of mounting parts is reduced to reduce the cost. [Structure] A handle 1 is attached to a main body cabinet 5 so as to rotate about a shaft 2, and a projecting piece 6 is protruded from a lower end of the handle 1. Further, in the main body cabinet 5, an arc-shaped guide hole 7 is formed along the movement locus of the projecting piece 6, and an elastic portion 8 which is in contact with the projecting piece 6 at the middle of the guide hole 7 is formed. It was provided so as to project inward.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a holding mechanism for a handle that is attached to a portable device such as a cassette tape recorder with a radio or a small-sized television receiver, and is rotated and pulled out when carrying.

[0002]

[Prior Art]

 8 and 9 show a conventional example, in which the handle 1 is rotatably attached to the holding portion 5'of the main body cabinet 5 via the holder 3 having the cylindrical shaft 4 and the protrusion 4'provided. First, as shown in FIG. 8, the holder 3 is mounted by bending the holder 3 inward from the bent portions 3 ′, 3 ′ and forming the cylindrical shaft 4 projecting on the holder 3 at the lower end of the handle 1. While inserting into the hole 2 ', a protrusion 4'protrudingly provided on the other side of the holder 3 is fitted to the cylindrical shaft 4, and the holder 1 is rotatably held by the holder 3, and then the holder 1 is rotated. The hooks 3 "and 3" of No. 3 are inserted into the locking holes 5 "of the main body cabinet 5, and the holder 3 is attached to the holding portion 5'of the main body cabinet 5 so as not to fall off.

[Problems to be solved by the device]

 In the conventional attachment of the above-mentioned conventional handle, since the rotation fulcrum side of the handle is clamped by the holder, inadvertent rotation of the handle is prevented by friction between the two, but wear and heat deformation due to use etc. If the adherence between the two is reduced due to this, it becomes impossible to hold the lantern in the pulled-out state, which reduces the handleability and makes a collision noise when the lantern is stored, which impairs the quality of the lantern. There is a problem in that minute vibration noise may be generated due to external vibration.

In order to improve this point, it is necessary to attach a cushioning material such as rubber to the contacting portion of the handle, which increases the number of assembling steps and causes a cost increase. It had a problem that

[0005]

[Means for solving the problem]

 In the present invention, in order to solve the above-mentioned conventional problems, a protruding piece is provided at the lower end of the handle, and an elastic portion is provided inwardly at a predetermined position on the main body cabinet to which the handle is pivotally attached. A guide hole having a substantially arcuate shape is provided.

[0006]

[Action]

 The elastic portion provided in the guide hole abuts the protrusion at the lower end of the handle to hold the handle in the retracted position or the retracted position, and to apply a certain braking force to the handle during the turning operation. It works.

【Example】

 FIG. 1 is a side view of a main part of an embodiment showing a storage state of a bag, FIG. 2 is a rear view of FIG. 1, and FIG. 3 is a sectional view taken along the line A-A ′ of FIG. As shown in the figure, a holding portion 5'is formed at a predetermined position of the main body cabinet 5 of the portable device, and the holding portion 5'is provided with a handle 1 which is rotatable about a projecting shaft 2. It is worn. A projecting piece 6 is projectingly provided on a lower end of rotation of the handle 1 (on the left side in the drawing), and the projecting piece 6 has an arc shape formed on a curved portion near the rotation fulcrum of the holding portion 5 ′. The guide hole 7 is inserted. An elastic portion 8 is formed so as to project inward in the middle of the guide hole 7, and the width of the guide hole 7 is narrower than both ends.

The handle holding structure of the present invention has the above-mentioned structure, and when the front end (right side in the figure) of the handle 1 is pulled up from the state shown in FIG. As it rotates about the center, the projecting piece 6 provided on the lower end side spreads out the elastic portions 8 and 8 of the guide hole 7 as shown in FIGS. 6 and 7, and enters between the elastic portions 8 and 8. Then, when the handle 1 is further pulled up, the projecting piece 6 fits into the other end of the guide hole 7 and stops as shown in FIGS. 4 and 5. Therefore, in this state, the handle 1 is held so that the device can be carried.

Then, in order to store the brace, the bladder 1 may be rotated in the opposite manner to the above, whereby the projecting piece 6 fits into the end portion of the guide hole 7 on the other side. It is stopped and the holding handle 1 is held in the stored state without rattling. At the time of this turning operation, since the projecting piece 6 passes between the narrow elastic portions 8 of the guide hole 7, there is no risk that the handle 1 will suddenly fall into the stored state due to the frictional force of both. There is no unpleasant collision noise.

As described above, in the holding structure of the handle according to the present invention, the handle is pivotally drawn out or stored.

[0011]

[Effect of the device]

 As described above, in the holding mechanism of the present invention, the projecting piece is in contact with the elastic portion of the guide hole only when it is turned, so that the hand should not turn freely when housed or pulled out. In addition to being held, a certain amount of braking force is applied at the time of turning operation, so that the handle does not turn carelessly and generate a collision sound, or it receives a vibration and a vibration sound is not generated. . Further, the click feeling when the projecting piece crosses over the elastic portion makes it easy to sense that the handle has rotated to the rotation end position, which improves the operation feeling. Furthermore, since the elastic part is normally pressureless, there is no fear of being deformed under pressure like the conventional ones, the wear accompanying use is minimal, and the function deteriorates over a long period of time. Never invite. Further, according to the present invention, since the holder as shown in the conventional example is not required and the dimensional accuracy as in the conventional case is not required, the product yield is improved, the manufacturing and assembling are easy, and the cost is reduced. It has an excellent effect.
