Description

[Detailed Description of the Invention] Industrial Application Field This invention is used for hanging video equipment, cassette decks, or their carrying bags.

Prior Art Such a hanging band fastening device can engage and disengage with a single touch, and
However, once engaged, there is a need for something that will not accidentally come off during normal use.

Therefore, conventionally, for example, Utility Model Application No. 51-108509,
Various devices have been devised and implemented, as seen in Utility Model Publication No. 53-94010, Utility Model Publication No. 53-486, etc., but in some cases an engaging pin that protrudes larger than the outer surface of the device is provided on the main body side of the device. Since a hole into which this engaging pin can be fitted is provided on the fastening tool side and the two are freely engaged and disengaged, the pin protruding from the outer surface of the main body becomes a hindrance when it is removed. In addition, there is a risk that it may collide with other equipment and damage the outer surface, and the internal structure of the fastening device is complicated and operation is troublesome.

Problems to be solved by the invention This invention was made in view of the problems of the conventional technology, and its purpose is to make it possible to easily attach and detach the fastening device with a single touch operation. In addition, once the engagement is performed, it is securely engaged and does not accidentally come off or move loosely, and a conventional engagement pin that protrudes toward the main body side is provided on the fastening tool side to prevent protrusions from the main body side. It is an object of the present invention to provide an anchoring device for a hanging band, which has a simple structure on the anchoring device side, operates smoothly and reliably, and can be implemented at low cost.

Means for Solving the Problems In order to achieve the above object, the hanging band anchoring device of the present invention has a shallow box shape with an open surface side, and has an attachment part formed at the upper end to the extreme end of the band. It is a fastening tool, and on the back side of the fastening tool,
A fixed engagement pin is fixed such that an upward locking collar that can be engaged with the engagement hole on the main body side from below projects, and a fixed engagement pin is attached below the fixed engagement pin parallel to the axis. A retractable locking pin is provided on the main surface of the main body of the anchor so as to close the opening, and a locking pin is provided which slides on the locking pin and is inserted into the opening hole together with the fixed engagement pin. An operating cover plate that can swing like a seesaw around a supporting shaft is fitted, and the rear end of the lock pin is connected to the lower end of this operating cover plate with a connecting pin, and the locking pin is inserted into the hollow part of the main body of the fastening tool. A spring is provided that presses the upper end of the operating cover plate outward from the inside to apply elasticity to the lock pin in the direction of protrusion.

It is preferable that the above-mentioned fastening device has an outer surface portion at the upper end of the operation cover plate as an operation portion.

Embodiment As shown in FIGS. 2 and 3, the anchor main body 1 is formed into a shallow box shape with an open front surface, and the operation cover plate 2 is fitted into the fitting part of the open part. A mounting portion 4 for the band 3 is provided at the upper end of the main body 1, and the end of the band 3 is inserted and attached to the mounting portion 4.

The fixed engagement pin 5 utilizes a bolt-like member having a head 5b at the tip of a shaft portion 5a.
An upward locking collar 6 is integrally formed on b. The locking collar 6 is eccentric with respect to the shaft portion 5a and the head portion 5b. This engaging pin 5 is immovably fixed by screwing a nut 7 onto the shaft portion 5a from the inside so that the head and locking collar 6 protrude toward the rear surface (back surface) of the main body 1.

The lock pin 8 is attached to the lower side of the engagement pin 5 parallel to its axis, and is provided in the main body 1 so as to be able to slide forward and backward in the axial direction. Make it more accessible.

The operation cover plate 2 is provided with pivot shafts 10 on both the left and right sides, which are press-fitted into the fitting grooves 11 on the main body 1 side, and are normally closed by spring pressure using the spring 12 inside the upper part. Do it like this. A lock pin attachment part 13 is provided on the inner surface of the lower part of this cover plate 2, and the connecting pin 1 is provided with a lock pin attachment part 13.
4, the lock pin is connected to the cover plate 2, and is made to appear and retract by operating the cover plate.

The opening hole 16 on the main body 15 side is the head part 5 of the engagement pin 5.
The hole is made into a circular hole whose diameter is equal to the diameter of b plus the thickness of the lock pin 8.

Function The anchoring device main body 1 is anchored to the main body 15 of the equipment as follows.

First, with the engaging pin 5 of the main body 1 aligned with the opening hole 16, the locking collar 6 is inserted into the opening hole 16 so that the main body 1 is tilted forward and scooped up from under the abutment. Since the locking pin 8 abuts against the lower edge of the opening hole 16, if it is inserted as it is, it will resist the bias of the spring 12 and sink into the hole 9, but when the main body 1 moves from the inclined position to the normal upright position, the opening hole 16 At that moment, it rushes into the opening hole 16 due to the spring pressure. When the engagement pin 5 and lock pin 8 are fitted into the opening hole 16 at the same time, the main body 1 cannot be removed in any direction, front, back, left, or right, and the lock pin 8 sticks out against the main body 15 and cannot be tilted. There's no need to worry about it coming off.

When removing the fastening tool, push the upper part 2a of the cover plate 2 inward. Then, as shown by the chain line in FIG. 2, the lower part of the cover plate 2 opens against the bias of the spring 12 using the pivot shaft 10 as a fulcrum. Due to this opening operation, the lock pin 8 connected to the lid comes out from the opening hole 16, so the engagement pin 5
becomes free and can be freely extracted from the opening 16.

Effects of the invention This invention consists of the above-mentioned structure,
The main body of the fastening device is provided with a fixed engagement pin and a lock pin that can be slid in and out by operating the lid, and both pins are simultaneously engaged with the opening on the main body side, so that once the engagement is performed, When it is removed, the engagement is maintained reliably and there is no need to worry about it accidentally coming off, and it can be rotated freely relative to the hole on the main body side, and once it is removed, there is no protrusion on the main body side, which is very convenient. Furthermore, engagement and disengagement can be easily performed with a one-touch operation by simply pressing the cover plate, and although the engagement pin is provided on the attachment device side, the structure is simple, the operation is reliable, and it can be performed at low cost. It is excellent in practical terms.
