Description

TECHNICAL FIELD The present invention relates to a strap fixture and a strap fixture attachment method used when attaching a strap to mobile information terminal devices such as smartphones and small tablet-type information terminal devices, their covers, or small accessories. More particularly, the present invention relates to a strap fixture and a method of attaching the strap fixture that enable stable carrying of portable information terminal devices, their covers, small accessories, etc., and that are simple and improve handling.

Conventionally, when carrying or handling portable information terminal devices such as smartphones and small tablet-type information terminal devices, users themselves attach various straps or notebook-type special covers to them. We have been trying to improve the protection, convenience, portability and transportability of the equipment, or to make it look better.

Such straps include various types of straps, such as sling straps, shoulder straps, neck straps, and hand straps.
Although the straps described above are adjustable in length, they generally have long cords or belts. Therefore, when the strap and the portable information terminal device are stored in a bag or pocket, for example, the string or belt of the strap is bulky and takes up storage space, and a part of the strap protrudes from the bag or pocket. can occur.

In order to solve this problem, a strap attachment tool has been proposed in which a portable information terminal device and a strap are attached to both ends thereof. When the strap is attached to the portable information terminal device via the strap fixture, the strap can be easily removed from the strap fixture when the portable information terminal device is put in a bag or pocket. The terminal device can be stored in a bag or pocket.

In this case, a hollow portion is provided in the interior of the connecting fitting (B) into which the elastic body (D) is inserted along the central axis. ) is inserted through an elastic body (D) and a fixing ring (E). A part of the elastic body (D) protrudes forward from the connecting fitting (B) so as to cushion the bending of the attachment string (A), and the fixing ring (E) is located on the rear end side of the elastic body (D). The attachment string (A) passes through the elastic body (D) and the fixing ring (E) and is locked at the rear end side of the fixing ring (E) by a knot or a fixing member.
In this portable goods strap fixture, since the ring-shaped attachment string (A) is supported by the elastic body (D) portion protruding from the connecting fitting (B), the attachment string (A) can be easily connected during use. Bending near the fitting (B) is buffered. Therefore, it is possible to greatly improve the fraying and breakage of the attachment string (A) and to use it for a longer period of time.

In addition, Patent Document 2 below describes a school bag hook attached to a school bag, which includes a hook for holding a first belonging, a belt-shaped first loop portion through which a fixing ring of the hook is passed, and a belt of the school bag. A school bag hook is disclosed that includes a strip-shaped second loop portion for passing a purse and a strip-shaped third loop portion for holding a second personal item.
Since the second loop portion and the third loop portion can be opened and closed, the school bag hook can be easily attached to the school bag and can hold a plurality of belongings.

Japanese Patent No. 4403185 Utility Model Registration No. 3218173

In the portable goods strap attachment device disclosed in Patent Document 1, since the ring-shaped attachment string (A) is supported by the elastic body (D) portion protruding from the connecting fitting (B), the attachment string (A ) fraying and subsequent cutting. However, this does not completely prevent the attachment string (A) from being cut due to aging, and if the attachment string (A) is cut, there is still a risk of losing the strap or, in some cases, the portable item itself. .

The school bag hook disclosed in Patent Document 2 holds a first belonging with a fixing ring of an eggplant hook, and can open and close a belt-shaped second loop portion and a belt-shaped third loop portion, so that a belt-shaped third loop portion can be opened and closed. A belt of a school bag can be passed through the second loop portion, and a second belonging can be held by the belt-shaped third loop portion. However, for example, if the belt-shaped second loop part or the belt-shaped third loop part were to be opened for some reason, the school bag hook itself would drop off from the school bag, or the second belongings would fall. There is a risk that it will be lost. In particular, if the belt-like third loop part is unintentionally opened, there is still a risk of losing the second belonging.
