Description

[Detailed description of the invention] "Field of industrial application" This invention relates to the improvement of a belt locking tool, and more specifically, to the improvement of a belt locking tool, and more specifically, to removably lock the upper end of the backpack belt of a backpack, etc., to the main body of the bag. The present invention relates to improvements in suitable belt anchors.

``Prior Art'' Conventionally, the upper end of the backpack belt of a backpack bag is usually fixed to the bag body in a non-removable manner, and in some cases, the top end of the backpack strap of a backpack bag is attached to the top center of the surface that touches the back of the backpack bag (hereinafter referred to as the back plate). A ring called a "back ring" for connecting the upper ends of the backpack belts is attached to the back belt, and an eggplant ring is provided at each end of the pair of backpack belts, and the lower part of each backpack belt is attached to the bottom of the bag body or A pair of rings (hereinafter referred to as bottom rings) arranged on both sides of the lower part of the back plate, which are fixed to each one, and the upper part is also an eggplant ring, which is fixed to the above-mentioned back rings, or a single backpack belt. One end is fixed to one bottom ring, and the other end is passed through the back ring and then fixed to the other bottom ring.

Furthermore, Japanese Utility Model Application No. 61-55825 has been proposed as a locking tool for removably locking this type of belt.
This conventional example is composed of a mounting member provided with a tube portion, and a trapezoidal frame body and a rod that can be raised and lowered, the proximal end of which is fitted into the tube portion in a rotatably overlapping state, and a rod,
The tip of the rod is designed to protrude outward from the tip of the frame and engage with the tip of the frame when it is in the above-mentioned fitted state, and the belt to be carried on the back has both ends fixed to the bottom ring with eggplant rings. The two-fold part of this backpack belt is passed through the frame from below, and the rod is passed through the two-fold part.When a bag is carried on the back with the backpack belt, the two-fold part of the backpack belt is inserted into the rod. The projecting end portion of the shoulder strap is pressed in such a direction that it engages with the end of the frame body, thereby locking the backpack belt in the middle.

``Problems to be Solved by the Invention'' However, the above-mentioned conventional fasteners have the disadvantage that attaching and detaching the belt is quite complicated. Recently, due to the convenience of commuting to school by bicycle,
The so-called ``two-way bag,'' which is used as a backpack when commuting to school, and then removed from the bicycle strap and used as a handbag, is becoming more and more widely used. The development of a fastener is desperately needed.

``Purpose'' Therefore, this invention was made in view of the above,
The object of the present invention is to provide a belt locking tool that can lock and unfasten a belt with a simple operation.

``Means for Solving the Problems'' In line with the above-mentioned purpose, the structure of the present invention, which is summarized in the scope of the above-mentioned utility model registration claims, is to solve the above-mentioned problems by providing longitudinal parallel guides on both sides of the surface. The protrusions 11, 11 are provided with a spring receiving protrusion 12 at the lower center.
A cover body 40 is fixed to the front side of the base plate 10 and has a hook portion 41 connected to the top thereof, extending above the base plate 10 and bulging toward the front side.
and a vertical groove in which the spring receiving protrusion 12 is loosely inserted into the center of the main body portion 21, which is interposed between the substrate 10 and the cover body 40 and has a width that fits between the parallel guide protrusions 11, 11. 22, the main body part 2
The upper part of the board 10 that projects upwardly has a locking part 23 having protrusions 23a, 23a that protrudes laterally at the upper end, and the lower part that projects downwardly of the board 10 has a protruding part 24a that protrudes laterally on both sides. , 24a and a finger hook portion 24b protruding toward the surface side, the sliding plate 20 is integrally formed with the locking/finger hook portion 24; 22 and the top surface 22a of the cover body 40, and normally biases the sliding member 20 upward so that the upper part of the sliding member 20 closes the opening of the hook portion 41 of the cover body 40. 30, and a belt attachment ring 50 held on one side by the hook portion 41.

``Function'' Therefore, in the belt locking device of the present invention, one end of the belt 60 is fixed to the belt attachment ring 50 using the conventional method, and one side of the belt attachment ring 50 is attached to the cover body as shown in FIG. 40 into the hook part 41. Then, in the normal state, since the sliding plate 20 is urged upward by the compression spring 30,
The opening of the hook portion 41 is closed at the top of the sliding plate 20, and the belt attachment ring 50 is held so as not to fall off. It goes without saying that the substrate 10 is fixed to a main body such as a bag.

Therefore, in order to attach and detach this belt attachment ring 50, hook your finger on the locking/finger hook part 24 of the sliding plate 20,
The sliding plate 20 is pulled down against the biasing force of the compression spring 30 as shown by the chain line in FIG.
Then, the upper part of the sliding plate 20 is lowered below the hook part 41 on the back side of the hook part 41, and
Since this hook portion 41 is opened, it can be attached and detached by inserting and removing one side of the belt attachment ring 50 from this opening.
If you remove your finger, the sliding plate 20 will release the compression spring 3.
It acts so that it moves upward with a biasing force of 0 and returns to the position shown by the solid line in FIG.

``Example'' Next, an example of the present invention will be described below with reference to FIGS. 1 to 5.

The belt locking device of the present invention includes a base plate 10 and a sliding plate 2.
