Description

[Detailed explanation of the invention] [Industrial application field] This invention is a backpack that can be easily and securely attached to the frame side of a backpack, shoulder bag, backpack power sprayer, etc., and that can be mass-produced. This relates to a connecting fitting for a band.

[Conventional technology]

Conventionally, when attaching a shoulder bag, shoulder bag, backpack power sprayer, or other backpack strap to be hung on the shoulder to the frame of these devices or to the attachments attached to the frame, a bent piece was folded at the appropriate place on the linear body. After bending and forming a connecting metal fitting, and assembling a backpack band into the space partitioned by this bent piece, inserting the tip of the bent piece into the through hole of the frame or fixture. It has been proposed that the backpack band can be locked in an appropriate position on the frame or attachment by rotating the connecting fitting.
(For example, see Japanese Utility Model Publication No. 54-34805.) [Problem to be solved by the invention] In the connecting fittings described in the section of the prior art,
After inserting the tip of the bent piece into the through hole of the frame or the fitting attached to the frame, move the connecting fitting to the position where it passes through the bent part of the bending piece. Since the bending piece can be set in the desired position, it is necessary to drill a through hole in the frame or the fixture itself through which the tip of the bending piece should be inserted. Since the connecting fitting must be rotated until it passes through the curved portion, there is a problem in that the user feels troublesome when attaching and detaching the connecting fitting from the frame or the fixture.

This idea was proposed in view of the problems mentioned above, and its purpose is to create a backpack strap that can be easily and quickly attached to and detached from the frame, and that can be mass-produced without changing the structure. The purpose of the present invention is to provide a connecting metal fitting.

[Means to solve the problem]

In order to achieve the above-mentioned object, the connection fitting of the backpack band in this invention is a connection fitting formed by winding a linear body made of elastic steel that is hung on one end of the backpack band of an item, etc. A laminated locking part that is wound in a ring shape with each end of the shaped body facing the center and having a predetermined gap, and a triangular connecting part that intersects the linear parts on the side facing these locking parts. are bent and formed integrally, and a backpack band is hung on the connecting portion, and the locking portion can be freely engaged and detached from a holder fixed to the utensil or the like.

〔Example〕

Embodiments will be described below with reference to FIGS. 1 to 4. The locking parts 1 and 2 are formed by winding the ends a and b of an elastic steel linear body such as iron wire or piano wire toward the center of a substantially circular shape with one end open. , these locking portions 1 and 2 are held in a stacked state with a predetermined gap C interposed therebetween, and on the side facing these locking portions 1 and 2, the filament bodies are crossed and a triangular connecting portion 3 is formed. , and the connecting portion 3
The backpack band 6 is inserted through the folded portion e at one end of the backpack strap 6, so that the backpack strap 6 can be hung on the connecting portion 3. (See Figures 3 and 4) The locking portion 1,
The gap C between the two faces a receiver 5 attached to a frame 4 of an apparatus such as a backpack, a shoulder bag, or a backpack power sprayer so as to be freely insertable and removable. In the figure, 7 is a buckle.

[Effect]

Since this device has the above-mentioned configuration, when the connecting part 3 is inserted through the folded part e of the backpack band 6 and is to be secured to the holder 5 for an article, etc., the securing parts 1 and 2 are As shown in Fig. 3, hold it in a vertical state, then move it in the direction of the arrow in the gap C in this state, and rotate the locking parts 1 and 2 90 degrees to their original positions. (See Fig. 4) The locking parts 1 and 2 are securely locked to the receiver 5, and the backpack band 6
can be hung on the shoulder. In addition, when the locking parts 1 and 2 are released from the receiver 5, after rotating the locking parts 1 and 2 by 90 degrees in the same way as when locking, in the direction opposite to the arrow in FIG. The locking parts 1 and 2 are connected from the receiver 5 through the gap C.
It can be easily detached from the receiver 5 by moving.

〔effect〕

According to this invention, (i) the locking portions are formed in a laminated manner with a predetermined gap in between, so that when the locking portion is attached to or detached from the holder of an object, the holder is moved between the locking portions. The existence of a gap that allows the locking part to move forward and backward makes it easy to engage and disengage the locking part, and it is not necessary to remove the backpack band each time to connect and disconnect the support and the locking part, and in particular, it requires an abnormally large amount of labor. , does not require skill or experience,
Anyone can do it easily and quickly.

(ii) Since the locking part is formed in a laminated manner, there is no risk of the locking part becoming loosened, deformed, or detached from the receiver due to the weight of the equipment or long-term use, or breakage. Can be used safely for a long period of time.

(iii) Since the gap between the locking parts can be set arbitrarily, even if the thickness of the holder changes, the gap can be easily formed to accommodate this change, and mass production is possible without changing the structure itself. , it is possible to prevent a rise in production costs.

(iv) Since the connecting part is triangular, when connecting the backpack band to the connecting part, the backpack band can be easily connected by simply inserting the backpack band into the triangular space, bending it, and securing it with the buckle. Also, when carrying objects on your back for a long time, even if you swing them up and down or left and right,
The knapsack band is prevented from moving to the other side edge of the connecting part, so that the knapsack band does not cause discomfort to the operator due to twisting, and the durability of the knapsack band itself is not reduced.
