Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a buckle applied to, for example, a middle belt of a bag with a cover and a hook applied to other belts.

<Prior Art> Currently, as a bag for commuting to school, as shown in FIG. 5, a front fold a and a rear fold b are made into a foldable bottom gusset c and left and right side folds d, d. If the capacity of the stored object such as a textbook is small, it can be stored in a stable state without shaking or moving, and the bag itself It is known that it can be used without being bulky.

Further, in this type of bag, as shown in the figure, a pair of left and right sides are provided respectively on the back side of the cover lid e attached to the upper end of the front sash a and the pocket portion f and the like provided on the front side of the rear sash b. The outer belts g, g and the buckles h, h are provided opposite to each other, and in addition to this, the middle belt i for fastening and the buckle j are provided opposite to each other.

Here, as the buckle j of the middle belt i, the one as shown in FIG. 6 has been widely used.

In the buckle j, as shown in FIG. 6, a horizontal rod 1 is erected at a substantially middle portion of a frame body k bent by a wire rod in a substantially horizontally long rectangular plane, and a latch rod m is rotatably pivoted on the horizontal rod l. The belt n is connected to the horizontal rod l.

To use the buckle j, after inserting the middle belt i into the frame body k, a plurality of hook holes o formed in the middle belt i ...
By selecting any one of the hooking holes o among these, and inserting the above-mentioned hooking rod m into it, the middle belt i is connected.

<< Problems to be Solved by the Invention >> However, in the conventional buckle j, both hands must be used for the detaching operation of the middle belt i, and this is troublesome, so this is not actually used. As a result, the stored items in the bag in which the inner belt i is not used swings or fluctuates, which causes the bag to be deformed, which makes it difficult to use, or is still in a deformed state. Not only does the bag lose its shape and lose its durability when used in, but especially when it is opened during use, books that have been stored may pop out of the bag. It is also becoming.

Therefore, in order to solve the above-mentioned difficulties, the actual development of Sho 61-177009
As disclosed in Japanese Patent Laid-Open No. 2004-242242, the plate shape is bent into a hook shape, and a latching piece is inserted between the elastic substrate and the elastic end plate facing each other, whereby the elastic substrate and the elastic end plate are joined together. Although it has been proposed that it can be freely clamped in the gap, it is sufficient to insert the latching piece into the gap or pull it out, and its operability is better than that of the conventional example. However, when a large withdrawal force is applied to the hook piece unintentionally, the hook piece will slip out of the gap.
The risk that the cover or the like will be opened and the book or the like will be released from the bag when running as described above cannot be eliminated.

The present application has been made in view of the above-mentioned conventional circumstances, and in claim (1), not only can the attachment / detachment operation be relatively easy with one hand and can be performed quickly, and the locking state is large. Let's prevent it from being unintentionally disengaged by external force, so that anyone can actually use it without trouble, and also secure high reliability even for involuntary opening such as bags. That is the purpose.

Further, in claim (2), the object of claim (1) can be more reliably achieved by utilizing the dividing structure in which one member has elasticity.

<< Means for Solving the Problem >> In claim (1) of the present application, in order to achieve the above-mentioned object, a latching piece is provided from the rear end side of the substrate at a predetermined distance from the upper surface of the substrate. A male hooking device bent forward and a hooking lateral rod are formed on the front end, and the hooking parts are formed on the left and right sides of the hooking member in the front-back direction with respect to the hooking piece. A female hooking member having a substantially U-shaped plan facing toward the rear inside so that it can be hooked in a state where movement is blocked, and a belt connecting portion is formed at the rear portion.
Locking recesses are provided on the right and left sides of the base of the hooking piece, and a space between the hooking portions is set to be smaller than the lateral width of the hooking piece by a required dimension. It is the one we are trying to provide.

According to claim (2), in the female hooking device in the above-mentioned claim (1), the hooking lateral rods extending from both hooking parts are coaxially butted between the end parts. That is, the content is that it is divided.

<Operation> The male hook and the female hook are hooked as follows.

By hooking the one hooking portion of the female hooking tool to the one hooking recess of the male hooking tool, the hooking lateral rod of the female hooking tool is connected to the base plate and the hooking piece of the male hooking tool. When it is inserted between the hooks, the space between the hooks of the female hook is narrower than the lateral width of the hook of the male hook. Abutting the other end of the female hook, the female hook is diagonally crossed with the male hook.

In this state, rotate the female hook in the same plane so that the female hook is parallel to the male hook around the hooking point between the hooking recess and the hooking part. Then, the other hooking portion of the female hooking tool slides on the end edge surface of the hooking piece of the male hooking tool and is guided to the lateral end of the hooking piece. When the female hooking device is further strongly rotated in the same direction, (in claim (2), the hooking part is pressed outward by the hooking piece at this time, whereby the distance between the two hooking parts is increased. Is pushed out against the spring force.) As a result, the other hooking portion is disengaged from the end edge surface of the hooking piece and is engaged with the other hooking recess (at this time, claim (2)). In this case, the spring force returns the distance between the two latching parts to the original position.), And the latching part has both male and female parts even when the latching female latching device is pushed into or pulled out from the latching recess. End stop is latched in a state that does not detachment.

That is, if such a hooking state occurs, the male and female hooking tools may fluctuate back and forth, left and right, and up and down due to the lateral width of the hooking piece and the size difference between the two hooking portions. No, so the hook is retained.

When releasing the locking of both male and female hooks, first operate the female hook with respect to the male hook in a reversible manner to the above-mentioned hooking, so that the one hooking concave part and the hooking hook are first locked. It is possible to release the hook by removing the hook of the portion and then the hook of the other hook concave portion and the hook portion.

The above is the case where the female hook is detached from the male hook, but conversely, the case where the male hook is detached from the female hook is the same as described above. Can be done.

<< Embodiment >> An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 to 4, it comprises a male hook 1 and a female hook 2.

The male hook 1 is bent forward from the center of the rear end of the base plate 3 which is formed long in the left-right direction so as to be fixed to a bag or other member with eyelet fittings and is located above the base plate 3 and is bent forward. The latching pieces 4 thus formed are continuously provided.

The above-mentioned latching piece 4 has a vertical gap in which a later-described latching lateral rod 2b of the female latching tool 2 can be inserted between the back surface of the latching piece 4 and the upper surface of the substrate 3 with a slight gap in the vertical direction. The lateral width 1 of the base portion 4a, which is formed so as to hold P and rises from the substrate 3, in the left-right direction, extends horizontally from the upper end of the base portion 4a toward the front. It is formed to be narrower than the lateral width L which is the left-right direction of the tip portion 4b by a required dimension, so that the latching recesses 4c, 4c are formed on the left and right sides of the base portion 4a toward the outside, respectively. The tip portion 4b is recessed at a depth of about 1/2 of the dimensional difference between the lateral widths l and L of the tip portion 4b.

As described above, each hooking concave portion 4c, 4c formed as a concave curved surface
The left and right end surfaces 4d, 4d of the tip portion 4b connected to each other are formed into an arcuate convex curved surface, and further, the front end edge surface 4e of the tip portion 4b connected to the both end edge surfaces 4d, 4d has its center part forward. It is formed as an arcuate curved surface projecting toward the front side, so that the later-described hooking portions 2a, 2a of the female hooking tool 2 can be smoothly unhooked and unhooked.

The female hook 2 described above is different from the male hook 1 configured as described above.
The hooks 2a, 2a formed by projecting outward so as to have a substantially U-shaped plane on the left and right of the front end, and the substantially central portion on the front end side of the hooks 2a, 2a. , The respective end portions 2c, 2c are coaxially butted to each other, so that the latching horizontal rod 2b laterally provided in the left-right direction and the rear portions of the two latching portions 2a, 2a are respectively inwardly Inward bends 2d, 2d that project toward each other
And a belt connecting portion 2e connected via the belt and the belt connecting portion 2e are integrally formed.

The belt connecting portion 2e includes outward bending portions 2f and 2f that are bent outward from the rear ends of the inward bending portions 2d and 2d in a substantially U-shaped plane, and the outward bending portions 2f. , 2f, which are connected to the rear ends of the horizontal rods 2g, and the outward bending portions 2f, 2f, which are composed of belt hanging rods 2h erected so as to be movable in the front-rear direction. .

The belt 5 is hung on the belt hanging rod 2h, both ends of the belt 5 are extended backward through the lower side of the horizontal rod 2g, and the belt length fixed to one end of the belt 5 is fixed to the belt insertion hole 6a of the adjustment metal fitting 6 at the other end. By inserting the belt 5, the length of the belt 5 can be adjusted.

Further, the female hook 2 is provided with the inward and outward bent portions 2d, 2d, 2f, 2f as described above, thereby imparting the spring property to both the hook portions 2a, 2a. Both the hook portions 2a, 2
A is elastically deformable outward in the left-right direction against the spring force and elastically recoverable inward.

Further, the space interval l'between the two hooking portions 2a, 2a in the female hooking tool 2 is determined by the two hooking recesses 4c, 4c in the male hooking tool 1.
And the width L of the tip 4b
It is set narrower than the required size.

Here, the male hook 1 is formed by punching a metal plate with a press and then bending the hook 4 while the female hook 2 has a circular cross section or an arbitrary shape. It is possible to bend and form one polygonal metal wire into a desired shape, but it is also possible to form a metal plate by punching a metal plate by pressing.

When the above-mentioned buckle is used as a belt stopper in the bag as shown in Fig. 5, the male hook stopper 1 is fixed to the upper surface of the rear lathe b by means such as eyelet fittings or screws not shown. On the other hand, the female hook 2 is fixed to the inner surface of the cover e by sewing one end of the belt 5 connected to the hook 2 to the inner surface of the lid e.

To hook the female hook 2 on the male hook 1, as shown in FIG. 3, one hook 2a is hooked on one hook recess 4c, and the hooking point is set. When the female hook 2 is rotated in the direction of the arrow q shown in the figure, as shown in FIG. 4, the other hook portion 2a moves from the front end edge surface 4e of the hook piece 4 to the one end edge surface. 4d
The other hooking portion 2a comes into engagement with the other hooking recess 4c.

In such an operation, in the illustrated example of claim (2), the female hook 2 is pressed outward by the contact with the hook piece 4, so that both hook portions 2a, 2a resist the spring force. Then, it is easy to fit by being pushed out, and at the same time when the above-mentioned engagement is completed, the both locking portions 2a, 2a are elastically returned to the inside by the spring force.

Next, when removing the male and female hooking devices 1 and 2 from the hooking state shown in FIG. 2, one end of the female hooking device 2 is attached to the male hooking device 1 in the hooking state shown in FIG. By rotating in the direction opposite to the time, that is, in the direction of the arrow r in the same figure, the hook 2a is removed from the hook recess 4c,
By further rotating, the state advances from FIG. 4 to FIG. 3 and the latch is released.

At this time, in the illustrated example of claim (2), since both the hook portions 2a, 2a are pushed outward against the spring force,
The operation of releasing the latch can be easily performed.

<< Advantages of the Invention >> Since the present invention is configured as described above, in claim (1), the female hook is hooked on the hook piece of the male hook to rotate in a predetermined direction. By doing so, both male and female hooks can be hooked, and in the hooked state, the female hooks can be unlocked by rotating the female hooks in the opposite direction to the above. The locking or unlocking can be easily and quickly performed by an easy operation with only one hand, and the buckle can be used easily.

In addition, at this time, no matter whether the force is applied from the front, back, left, or right, it can be securely hooked without inadvertently detaching, so that the contents in the bag do not pop out, Therefore, it is possible to provide a highly reliable device that does not neglect the hanging operation.

Further, according to claim (2), since the latching lateral rod has a divided structure and has elasticity, the engaging and disengaging operation of both male and female latches can be performed more smoothly.
