Description

[Detailed description of the invention] (Field of industrial application) The present invention is a stopper used for hanging straps (shoulder straps) of shoulder bags, etc., which reduces the burden on the shoulders and prevents shoulders from slipping. This relates to a strap stopper.

(Prior Art) Various types of fasteners have been devised for attaching a hanging strap to a bag, such as a stopper that prevents the hanging strap from twisting, and a locking piece for preventing detachment at the hook opening. A stopper configured to prevent the hanging strap from easily detaching from the bag during use by means of an appropriate attached means, a stopper that makes it extremely easy to attach and detach the hanging strap to the bag, etc. On the other hand, it has been devised mainly with considerations such as ease of attaching the hanging cord, prevention of detachment during use, and prevention of twisting of the hanging cord.

(Problem to be solved by the invention) However, none of the conventional fasteners has been designed to reduce the burden on the shoulders when the bag is heavy and to make the bag feel light.
An elastic spring is installed inside to move the locking hook or the detachment prevention piece at the hook opening up and down. The reality is that no efforts have been made to make it difficult for people to fall, to make their shoulders less likely to shift, or to make their shoulders less painful.

The present invention was developed in view of the above points, and is particularly effective for medium-sized bags and large bags that place a large load on the shoulders. The purpose of the present invention is to provide a strap stopper that improves the wearability of the strap and prevents shoulder displacement.

(Means for Solving the Problems) The gist of the present invention to achieve the above object is that a U-shaped spring body is installed inside a U-shaped flexible protective tube, A locking ring is arranged at the upper center of the sliding tube for stabilizing the suspension string, which has an arc shape that fits the curved part of the protective tube and whose inner wall is in sliding contact with the outer wall of the protective tube. The strap stopper is characterized in that the strap is locked at both ends of a base tube provided with a locking hook at the lower center.

(Function) As described above, the strap stopper of the present invention can be attached to a bag by attaching the main stopper to the hanging string using the locking ring on the sliding tube, and attaching the main stopper to the bag side using the hook on the base tube. A hanging cord is attached to it. When in use, by moving the sliding tube so that it is slightly tilted toward the body (in other words, positioning it in the angular direction of the sling that hangs over the shoulder), the sling will always be stable on the shoulder regardless of the weight of the bag. This prevents shoulders from shifting or falling off, and reduces the feeling of weight. Furthermore, the U-shaped spring body not only makes it feel much lighter than its actual weight when walking, but also allows the spring body to move slightly from side to side using the locking positions at both ends as support points. Since the spring body is positioned in the same direction as the inclination of the flow pipe, that is, the direction of the hanging string, the expansion/contraction action and the cushioning action are performed efficiently, and the weight feeling can be further reduced.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

Fig. 1 is a perspective view showing one embodiment of the present invention;
The figure is a front view showing the state of use, and FIG. 4 is a front view showing the state in which the sliding tube has been moved.

In the drawing, 1 is a spring body, which is a cylindrical coil spring formed in a U-shape, and has a hanging strap (shoulder strap).
By interposing the spring body 1 between the bag and the bag, the feeling of weight on the shoulders when walking can be reduced to about half of the actual weight. 2 is a protection tube,
A U-shaped transparent tube having an inner diameter into which the spring body 1 can be inserted is ideal, such as a flexible transparent tube made of vinyl, which can be deformed as appropriate as the spring body 1 installed inside is deformed. It is formed by the material. The protective tube 2 is a member that prevents the spring body 1 from becoming dirty or damaged by rain, dust, etc., and also serves to position a suspension string, which will be described later. In this embodiment, the protection tube 2 is a transparent tube, but this is not particularly limited. 3 is a sliding tube, which is a tube member (made of a material such as PVC) that has an arc shape that fits the curved part of the U-shaped protection tube 2 and has an inner diameter such that the inner wall of the tube slides into contact with the outer wall of the protection tube 2. Considering the flexibility of the protective tube 2, the main sliding tube 3 is shaped so that it can be forcibly moved on the protective tube 2 by human power and does not move by itself during use. . Reference numeral 4 denotes a locking ring, which is a ring body that can be freely moved in any direction and is disposed at the position via a hook 4a fixed to the upper center of the sliding tube 3, and is locked to hooks provided at both ends of the suspension string A. to connect the main stop and the hanging string. Reference numeral 5 denotes a base tube, which is a tube member made of a material such as PVC with both ends curved upward, and spring locking hooks 6, 6 are fixed to both ends, and springs are attached to the spring locking hooks 6, 6. The main stopper is formed so that both ends of the main body 1 are locked and the spring main body 1 moves slightly from side to side using the locked position as a support point. A locking hook 7 is provided at the lower center of the base tube 5, and is locked to a ring on the bag B side to connect the main hook to the bag.

Therefore, in use, as shown in FIG. Adjust the inclination angle of the strap A to suit the inclination angle of the strap A, and position the strap A so that it hangs smoothly on the shoulder. When walking in this state, the bag does not tilt and always remains vertical, as shown in FIG. 5, and the hanging strap hangs on the shoulder at a constant angle. The feeling of weight on the shoulders is reduced by the expansion and contraction of the spring body 1, but as mentioned above, the angles of the hanging cord and the bag do not change, and the spring body 1 repeats expansion and contraction while being slightly deformed using both ends as support points. Therefore, the weight can be reduced most efficiently.

(Effects of the invention) As explained above, according to the invention, when the bag becomes a heavy object, it creates a feeling of lightness that cannot be achieved with conventional fasteners, and even if the bag is heavy, it does not stick to the shoulder. It has an excellent fit and feel, so the hanging strap does not easily fall off, your shoulders do not shift, your shoulders are less likely to hurt, and the burden on your lower back is greatly reduced, so it has a considerable physical effect. It can be said that the range of applications is wide and the commercial value is extremely high.
