Description

[Detailed description of the invention] The present invention allows the locking rod to be integrally and rotatably attached to the fastening plate by molding the locking rod and the fixing plate with different synthetic resins that are difficult to adhere to each other. This relates to a locking device that is worn on the body.

Conventionally, a locking rod is pivotally attached to a fixing plate that is attached to a bag, backpack, wall, etc., and a belt is attached to the locking rod.
In a locking device that locks a shoulder strap or a towel, etc., the locking rod is required to rotate, so the locking rod and the fixing plate are molded separately, and the locking rod and the fixing plate are molded separately. The locking tool was formed by fitting both ends of the locking rod and rotatably pivoting the locking rod to the fixing plate.

For this reason, if a strong force is applied to the locking rod, the locking rod is likely to come off from the fixing plate, making it difficult to ensure a strong pivoting connection between the locking rod and the fixing plate.

Therefore, the inventor of the present invention has proposed that by molding the locking rod and the fixing plate with different synthetic resins that are difficult to adhere to each other, the locking rod can be pivotally attached to the fixing plate integrally and rotatably. This discovery led to the creation of this invention.

To explain the locking device according to the present invention based on an example, as shown in Figs. 2, and a nylon 6 resin that does not easily adhere to the locking rod 1 is injected into the mold to form the fixing plate 2 (hereinafter, this molding method will simply be referred to as insert molding). ) and at the same time,
This is a locking device in which the locking rod 1 is rotatably attached to the pivot portion 4 of the fixing plate 2.

As shown in FIGS. 1 and 2, the locking rod 1 is
It is a generally triangular annular body with a slightly narrower diameter at the base to prevent left and right movement.

As shown in FIGS. 1 and 3, the fixing plate 2 is
A horizontally long rectangular parallelepiped-shaped pivot portion 4 on which a locking rod 1 is rotatably pivoted is connected to the upper part of the approximately heart-shaped plate portion 3,
A sewing groove 5 is carved near the outer peripheral edge of the plate portion 3 to facilitate sewing.

Further, although not shown, a sewing hole may be formed instead of the sewing groove.

Regarding the synthetic resins used, in the above embodiment, the locking rod 1 was molded from polyacetal and the fixing plate 2 was molded from nylon 6. It's okay,
There is no particular limitation, as long as it is a synthetic resin made of different materials that do not easily adhere to each other.

Next, to explain how to use the locking device according to the present invention when used in a backpack, as shown in FIG. 4, one end of the shoulder strap B of the backpack R is attached to the locking rod 1, Ryutsukusatsuku R
It is used by sewing it on the back of the

In the above embodiment, the explanation was given using a stopper used for bags, backpacks, etc., but as shown in FIGS.
is preformed, and the fixing plate 2 is insert molded,
The locking rod 1 may be rotatably pivoted to a horizontally long rectangular parallelepiped-shaped pivot portion 4 protruding from the center of a substantially rectangular plate portion 3 to provide a locking tool for hanging towels.

The present invention can also be applied to a bag handle 6 as shown in FIG. 7, a hanger 7 with a pants hanging ring 8 shown in FIG. 8, and the like.

In this way, the locking tool of the present invention integrates the locking rod 1 and the fastening plate 2 when forming the fastening plate 2 from the preformed locking rod 1, so that the fastening plate 2 can be pivoted. Since there is no need to make cuts in the part 4 or the locking rod 1, it will not come off, and even if the locking rod 1 has a small diameter, the fixing plate 2 will not come off.
This ensures a strong pivot joint and provides a product with excellent durability.

In the locking tool of the present invention, the locking rod 1 and the locking plate 2 are integrated when the locking rod 1 is formed in advance to form the locking plate 2, so even a small diameter locking rod 1 can be fixed. Board 2
It is possible to ensure a strong pivoting connection and to form a compact locking tool with excellent durability.

In the locking tool of the present invention, the locking rod 1 and the securing plate 2 are integrated when the locking rod 1 is formed in advance to form the securing plate 2, so that the locking rod 1 and the securing plate 2 are integrated. The assembly process can be omitted, and the locking device can be provided economically.
