Description

[Detailed Description of the Invention] The present invention relates to a portable device hanging device that is most suitable for application to, for example, portable VTRs, tape recorders, or other various portable electronic devices. As shown, a hanger 6 is provided on the portable device 1 and is configured to rotatably support the belt 4 and the metal part 5 of the handle between the pair of flanges 2 a and 2 b.
It is related to.

In the conventional hanging device 6 of this kind, when the device is carried, the metal part 5 falls down with respect to the hanging device 6 as shown in the figure, and tends to rotate in a state in which it is in pressure contact with both flanges 2a and 2b.

The rotation in this state causes the hanger 6 to be twisted, causing the hanger 6 to rotate and loosen due to a so-called wrench effect.

Therefore, conventionally, when attaching the hanging device 6 to the portable device 1,
It was believed that it was impossible to screw this in place at all.

This is because when screwed, the hanging tool 6 easily loosens and falls off due to the wrench effect.

For this reason, in the past, the hanging tool 6 was fastened to the portable device 1 by strongly crimping, but this crimping method had various problems.

That is, first of all, caulking is more troublesome and expensive to process and assemble than screwing, and it lacks compatibility.

In addition, recent equipment generally has a structure in which the outside of the body frame, such as a sheet metal chassis, is covered with a plastic exterior, but if the hanging device is attached to the plastic exterior, there is a problem with the strength, so it is difficult to hang it. The tool must be attached to the main body frame, and a notch must be formed in the exterior of the device to allow the hanging tool to escape, which is not desirable in terms of processing and appearance.

It is also conceivable to use a hanger to tighten the exterior and the main body frame together, but in this case, it would be impossible to attach or remove the exterior, so it would be completely impractical.

Therefore, the hanger cannot be used in conjunction with the set screws on the exterior, so a large number of set screws, etc. are required to attach the exterior to the main body frame, which increases the number of parts and assembly man-hours, leading to high costs. There is.

The present invention was devised in view of the above-mentioned circumstances, and is designed to prevent the hanging device from unexpectedly rotating and loosening due to the wrench effect of the belt and handle when carrying the shoulder strap. This is an attempt to provide a portable device that can solve many of the problems mentioned above all at once.

Embodiments of the present invention will be described below with reference to the drawings.

2 to 6 show the first embodiment, and as shown in FIGS. 1 and 2, 11 is a portable VTR, tape recorder, or other electronic device, for example. This figure shows a so-called portable device, and 12 is a body frame such as a sheet metal chassis, and 13 is an exterior made of plastic, for example, which covers the outside of the body frame 12.

On the other hand, the hanging device 15 referred to in the present invention has a pair of flanges 16a spaced apart from each other on the outer periphery, as shown in FIGS. 4 and 6.
, 16b are integrally molded, and the tips are configured to have male threads 17.

The hanging tool 15 is made of, for example, metal or hard plastic, and the above-mentioned flanges 16a
, 16b and 18, the shoulder rest is configured to rotatably support a belt or a handle.

A screwdriver insertion groove 19 is formed on the distal end surface of the flange 16b at the distal end, and a stepped portion 20 is formed at the base of the male thread 17.

A collar 22 having a pair of flanges 21a and 21b integrally formed on the outer periphery of both ends is rotatably fitted between the flanges 16a and 16b of the hanging tool 15.

In this case, the collar 22 is made of plastic, for example, and has a dividing groove 23 along the axial direction in a part of its circumferential surface.
is formed.

The collar 22 utilizes this groove 23 to connect the flanges 16 a and 16 b between the flanges 16 a and 16 b on the outer periphery of the hanging tool 15 .
It is freely rotatably fitted.

The diameters of the flanges 21a and 21b of the collar 22 are the same as those of the flanges 16a and 16b of the hanging tool 15.
The diameter is approximately equal to that of the

In this embodiment, the hanging tool 15 having the above structure is also used as a set screw for the external device 3 to the main body frame 12, and the structure thereof will be explained below.

First, a female threaded hole 25 is formed at one end of the main body frame 12, and an insertion hole 26 is formed in the outer device 3 in correspondence with this female threaded hole 25.

After fitting the outer device 3 to the outside of the main body tool 12, the hanging tool 15 is inserted into the insertion hole 26 with its male screw 17, screwed into the female screw hole 25, and tightened, so that the hanging tool 15 is attached to the stepped portion. 20 is crimped and fixed to the main body frame 12.

The outer device 3 is then tightened through the flange portion 16 a of the hanging tool 15 and fixed to the main body frame 12 .

Note that normally a pair of hanging tools 15 are used to attach the main body frame 12.
and attached to both sides of one end of the outer device 3.

The other ends of these are screwed with a small number of set screws 27.

After assembling as described above, the belt 29 and handle of the shoulder strap are attached to the pair of hanging tools 15.

In this case, the shoulder strap usually has metal parts 31 at both ends of the belt 29 for locking, which have daruma holes 30 as shown in FIG.
is attached, and the metal part 31 is attached to both flanges 16 a , 1 of the hanging tool 15 using the daruma hole 30 .
It is rotatably fitted and attached between 6b and 18.

However, at this time, the collar 22 is fitted to the hanging tool 15, and the metal part 31 is rotatably fitted between the pair of flanges 21a and 21b on the outer periphery of the collar 22. .

According to the hanger 15 configured as described above, when carrying the portable device 11 on the shoulder using the belt 29 or the handle,
As shown in FIG.
It comes into pressure contact with both flanges 21 a and 21 b of the hanging tool 15, but does not come into pressure contact with both flanges 16 a and 16 b of the hanging tool 15.

Therefore, even if the metal part 31 falls down and rotates as described above, the collar 22 only rotates, and the rotation of the metal part 31 strains the hanging tool 15, causing the hanging tool 15 to be rotated due to the so-called wrench effect. This can be prevented from happening.

Therefore, according to the above structure, there is no problem that the hanger 15 screwed to the main body frame 12 unexpectedly rotates, loosens, and falls off when being carried.

As described above, since the hanging tool 15 can be prevented from loosening,
The hanging tool 15 can be attached to the main frame 12 with a screw structure, and as a result, the hanging tool 15 can be used as a set screw for the external device 3.

As a result, the number of parts, the number of assembly steps, etc. can be greatly reduced, and costs can be significantly reduced, and the appearance is also very desirable.

Note that FIG. 7 shows a modification of the hanging device 15,
In this case, one of the flange 16b is shaped like a flange, a male thread 33 is integrally provided thereon, and a female threaded hole 34 is formed at the tip of the hanging tool 15.

When configured in this way, the collar 22 is attached to the hanging tool 15.
After inserting it into the tip of the flange 16 from its axial direction,
The collar 22 can be attached by screwing the male screw 33 into the female screw hole 34 and fixing it.

Therefore, not only is it easier to attach the collar 22, but the groove 23 provided on the collar 22 is no longer necessary.
This collar 22 can be constructed in a completely cylindrical shape.

Further, in this case, the collar 22 may be made of metal or hard plastic.

As described above, the present invention is a hanging device (A) having a threaded portion integrally provided at one end, and a pair of flanges integrally provided at an interval on the outer periphery.

(B) It shall be a hanging device that is screwed onto the portable device using the threaded portion mentioned above.

(C) A pair of flanges are integrally provided (smooth collars) on the outer periphery of both ends.

(D) The collar is rotatably fitted loosely between a pair of flanges of the hanger on the outer periphery of the hanger.

(E) The shoulder strap or handle is rotatably supported on the outer periphery of the collar between the pair of flanges of the collar.

This is a sling for a portable device characterized by comprising the above items (A) to (E).

Therefore, according to the present invention, (F) Even if the shoulder strap rotates in a state where the belt or the metal fittings of the handle are twisted diagonally with respect to the sling,
Only the collar is rotated together with the metal fittings, which prevents the hanger from being directly pried by the metal fittings and the resulting sputtering effect causing the hanger to rotate unexpectedly and come loose. It can be definitely prevented.

(G) Therefore, by using the threaded part integrally provided at one end of the hanging tool, the hanging tool can be screwed directly and extremely easily to the main body frame, etc. of the portable device. It is extremely easy to install the hanging equipment.

(H) However, during use, there are no inconveniences such as the above-mentioned screw-fastened hangings loosening unexpectedly and causing looseness, or unexpectedly falling off from the main body frame, etc., and the reliability is extremely high. expensive.

(I) Since the threaded part integrally provided at one end of the hanging tool allows the hanging tool to be directly screwed to the main body frame of the portable device, the hanging tool can be used to cover the exterior of the portable device. By aligning the two parts in the same line, the hanging tool can also be used as a set screw for the exterior of the main body frame.

As a result, the number of parts and assembly man-hours are greatly reduced,
It is possible to achieve a significant cost reduction, and it is also possible to significantly improve the appearance.

It can produce remarkable effects.
