Description

[Detailed description of the invention] The present invention is a handle attachment device for radio receivers and other various electronic devices, and in particular, it provides an appropriate frictional resistance to the rotation of the handle, and allows the angle of the handle to be freely set with respect to the cabinet. It is related to things that have been done in this way.

Fig. 1 shows a conventional example of this handle mounting device, which consists of a pair of mounting bases 3a, 3b made of Hewei resin, with flanges 2a, 2b integrally formed at one end of boss portions 1a, lb.
, and attach both the mounting bases 3a and 3b to their boss portions 1a and 3b.
lb, and are fitted into the end 4a of the handle 4, and screwed into the screw hole 5 formed in the end 4a of the handle 4,
These two mounting bases 3a are attached by screws 6 that can be firmly tightened.
, 3b from both sides, and tighten these flange parts 2a, 3b from both sides.
2b, the cabinet 7 is strongly clamped from both sides.

In this case, the frictional force between the flanges 2a, 2b and the cabinet 7 caused by the tightening force of the screws 6 provides appropriate frictional resistance to the rotation of the handle 4.

However, in this case, the structure is complicated, and the number of parts, processing steps, and assembly steps are large, resulting in a significant increase in cost.

In addition, variations in the tightness of the screws 6 will cause variations in the frictional resistance of the handle, resulting in inconsistent quality.Furthermore, if the screws 6 are not completely prevented from loosening, the handle will wobble after a short period of use. This caused defects such as the handle not being able to be set at the desired angle.

The present invention was devised to correct the above-mentioned defects, and has a structure that is extremely simple to manufacture and assemble, yet can effectively provide appropriate frictional resistance to the rotation of the handle. This is what we are trying to provide.

Embodiments of the present invention will be described below with reference to FIGS. 2 to 6B.

First, reference numeral 11 denotes a cabinet for a radio receiver and other various electronic devices, in which a main body 12 and a lid 13 are fitted into each other from the front and back in a butt-like manner and fixed with screws or the like.

In addition, 14 is a handle, which is almost U-shaped as a whole.
The left and right end portions 14a and 14b are bent inwardly so as to face each other.

The cabinet 11 is made of, for example, ABS resin, and the handle 14 is made of, for example, metal.

Reference numerals 15a and 15b indicate a pair of mounting bases, which are made of the same structural component integrally formed of low-friction resin such as polyacetal resin.

These mounting bases 15a and 15b each have a pair of flange portions 17, 18 integrally molded at both ends of the boss portion 16.

Both flange parts 17 and 18 are disk-shaped, but a projecting part 19 is integrally formed in a part of the peripheral part of the inner flange part 17, and both end surfaces 20a and 20b of the projecting part 19 are formed integrally with each other. is formed on the abutting surface against a stopper, which will be described later.

Further, an arcuate hole 21 is formed in the periphery of the flange portion 17 on the opposite side from the projecting portion 19, and the outer side of the arcuate hole 21 is formed into an elastic arcuate piece 22. There is.

Further, an engagement hole 23 for engaging both ends 14 a and 14 b of the handle 14 is formed in the center of the boss portion 16 .

The engaging hole 23 has a rectangular cross-section that matches the cross-sectional shape of the end portions 14a and 14b.

On the other hand, in a pair of handle attachment portions on both left and right sides of the cabinet 11, semicircular holes 24a and 24b are formed at the abutting portions of the main body 12 and the lid 13, respectively.

The inner diameters of these semicircular holes 24a, 24b are approximately equal to the outer diameters of the boss portions 16 of the mounting bases 15a, 15b.

In the vicinity of these semicircular holes 24 a and 24 b, a pair of stoppers 25 a are provided at one location (or two locations) each on the inner surfaces of the main body 12 and the lid body 13 in the left and right direction.
, 25b are, for example, in an asymmetrical state, and the main body 12 and the lid body 13 are each integrally shaped.

According to the handle attachment device constructed in this way, first, the pair of attachment bases 15a and 15b are asymmetrically inserted into both ends 14a and 14b of the handle 14 through these engagement holes 23, and engaged. Stop.

These two mounting bases 15 a and 15 b are attached to the main body 12 of the cabinet 11 between the two flanges 17 and 18.
and the lid body 13 have semicircular holes 24 a , 2 facing each other.
4b, and in this fitted state, the main body 12 and the lid 13 are integrally connected by screwing or the like.

This allows the handle 14 to fit into the semicircular holes 24a, 24b at the outer periphery of each boss portion 16 of both mounting bases 15a, 15b.
It is supported on the inner circumference of the

The handle 14 is rotatable about the axis of the boss portion 16 relative to the cabinet 11.

However, at this time, the gap between both flange portions 17.
Since the peripheral portions 24b are shaped to be smaller than the thickness of the peripheral portions 26a and 26b, when both the mounting bases 15a and 15b are fitted into the semicircular holes 24a and 24b as described above, These flange portions 17, 18 elastically sandwich the peripheral portions 26a, 26b from both left and right sides.

As a result, both the flange portions 17, 18 and the peripheral portion 26a,
26b provides an appropriate frictional resistance to the rotation of the handle 14 as described above, and the angle of the handle 14 relative to the cabinet 11 can be freely set.
It is structured like a sea urchin.

Moreover, according to this handle attachment device, when the handle 14 is attached to the cabinet 11 as described above, as shown in FIG.
The arcuate pieces 22 are arranged to be pressed against the respective stoppers 258 and 25b against elasticity.

Therefore, when the handle 14 is rotated, an appropriate frictional force is obtained between the arcuate piece 22 and the stoppers 25a, 25b, and stable frictional resistance is provided by the rotation of the handle 14.

In this case, by appropriately selecting the size, length, shape, number, position, etc. of the holes 21, the elastic pieces (for example, arc-shaped pieces) 2
Since the elastic force of 2 can be adjusted, a desired frictional resistance can be easily obtained.

Note that the handle 14 is attached to both mounting bases 15a at both ends of its rotation range.
, 15b alternately abut against a pair of stoppers 25 a , 25 b to restrict their rotation angles.

However, when the mounting bases 15a and 15b having the above-mentioned shapes are formed by injection molding using resin, both of these flange portions 17. Tapered surface 17a on the opposite surface of 18,
18 I can do a.

Similarly, this tapered surface is connected to the peripheral portions 26 a and 2 of the semicircular holes 24 a and 24 b of the cabinet 11.
6 b can also be done.

When these tapered surfaces are brought into close contact with each other when the handle 14 is attached to the cabinet 11 described above, the competition (pushing action) between the tapered surfaces due to the elastic clamping of both flanges 17 and 18 causes The main body 12 and the lid 13 of the cabinet 11 will be pushed open from each other, which may lead to a truly inconvenient situation.

In such a case, as shown in FIG. 6B, the peripheral portions of both flanges 17 and 18 are removed by utilizing the contraction effect of the composite resin during the injection molding of the composite resin of the mounting bases 15a and 15b. When the handles 14 and 18 are curved inward to form a dish shape, the above-mentioned tapered surfaces 17a and 18a are not formed on the opposing surfaces of both flanges 17 and 18, and when the handle 14 is attached to the cabinet 11 as described above, Both flanges 1
7.18 is the outer peripheral part 17b, 18b of the opposing surface, and the peripheral part 26a, 2 of the said semicircular hole 24a, 24b
6 b is crimped.

As a result, when the mounting bases 15a and 15b having the above structure are used, the above-mentioned push-open phenomenon between the main body 12 and the lid 13 of the cabinet 11 due to competition between the tapered surfaces does not occur, and the handle 14 can be rotated stably. I can do it.

Note that FIG. 7 shows a modified example, in which a recess 28 is formed in a part of the arc-shaped piece 22 of the mounting bases 15 a and 15 b, and this Recess 2
8 applies a light impact (
The handle 14 can be held together with a click feeling).
It is designed so that it can be temporarily fixed at a position such as the center.

When constructed in this way, the mounting bases 15a, 15
There is an advantage that b can also be equipped with a click function.

In the embodiments described above, the handle is attached to the cabinet, but it is also possible to attach it to the chassis in the same way.

The present invention provides a handle attachment device in which the handle is rotatably attached to the cabinet or chassis of an electronic device via the support member attached to the end of the handle as described above. The member includes a boss portion for supporting the handle and a pair of flange portions integrally provided at both ends of the boss portion, and the electronic device is placed between the pair of flange portions. By inserting the cabinet or chassis, the support member is rotatably supported with respect to the cabinet or chassis, and the center part and the peripheral part of one of the pair of flange parts are connected. A slit is provided in a part of the space so that the outer circumferential portion of the slit I becomes an elastically deformable part that can be elastically deformed in the radial direction of the flange part, and this elastically deformable part is elastically abutted against a cover that can come into frictional contact. The present invention relates to a handle attachment device characterized in that a contact portion is provided on the cabinet or chassis.

Therefore, the structure is very simple, and the number of parts, processing man-hours, and assembly man-hours can be greatly reduced, and costs can be significantly reduced.

In addition, there is almost no variation in the frictional resistance of the handle, resulting in stable quality, and there is almost no possibility that the handle will rotate too hard or become loose after a short period of use. Who?

Further, by appropriately selecting the size, length, shape, number, position, etc. of the slits provided in the flange portion, it is possible to extremely easily set the optimum frictional resistance for rotation of the handle.

Furthermore, the handle can be stably set at the desired angle, etc.
