Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a buckle for a belt used to fasten pants or the like to the human body.

[Summary of the idea]

In the buckle of the present invention, both the left and right ends of the belt are inserted inside.

[Conventional technology]

FIG. 9 shows the configuration of a conventional belt device. A buckle 1 in the figure has a locking portion 2 formed at its center, and one end of a belt 3 is locked to this locking portion 2. This end is sutured so that it cannot be separated from the locking part 2. A pin 4 is rotatably locked in the locking part 2, and the belt 3 can be fixed by inserting it into any one of the holes 5 formed at the other end of the belt 3. It can be used at any desired length.

In a buckle with such a configuration, if the user's body becomes fat or thin and the length cannot be adjusted using the existing hole 5 alone, a new hole 5 must be formed. Must be. However, it is difficult for general users to form such holes 5 neatly.

Therefore, a buckle having a structure as shown in FIG. 10 has been devised. A buckle 1 in the figure is provided with a flange 11, on which a pressing portion 12 is rotatably supported. A locking portion 13 is further rotatably supported on the pressing portion 12 . Locking part 1
A stopper 14 is attached to the belt 3, so that when one end of the belt 3 is cut at an arbitrary position and inserted into the locking part 13, it can be locked by the serrated part 15.

[Problem that the invention attempts to solve]

In the buckle having the configuration shown in FIG. 10, the cut surface of the belt is hidden inside the locking part 13.
Compared to the buckle shown in the figure, the user can adjust the length relatively easily and aesthetically. However, since one end of the belt is cut,
The disadvantage is that the belt cannot be made longer if the user has gained weight. Further, the tip of the serrated portion 15 is sharper than the tip of the pressing portion 12, which has the disadvantage of damaging the belt.

[Means for solving problems]

In the buckle of the present invention, a first plane part disposed on the human body side, a second plane part parallel to the first plane part and disposed on the side away from the human body, and two end parts of the belt. A coupling part that joins the first flat part and the second flat part so that both can be inserted into the inside, and a connecting part that connects the first flat part to the second flat part so as to press the belt against the first flat part. a first pressing portion movably supported by the second flat portion or the coupling portion; and a first pressing portion movable relative to the second flat portion so as to press the belt against the second flat portion. A second pressing part supported by the flat part or the joint part.

[Effect]

The first plane part and the second plane part are connected by a connecting part, and both ends of the belt can be inserted between them. Then, the double-inserted belt is pressed by the first pressing part and the second pressing part against the first flat part and the second flat part, respectively.

〔Example〕

1 to 3 show the structure of the belt device of the present invention. In the figure, reference numerals 21 and 22 are planar portions facing each other substantially parallel to each other, with the planar portion 21 being placed on the user's body side, and the planar portion 22 being placed on the side away from the user's body. The plane parts 21 and 22 are made of metal or the like, for example. Although the planar portions 21 and 22 are shown as so-called planar shapes in the drawings, they may be formed into curved surfaces with a slight curvature, for example, so as to follow the shape of the human body. Reference numeral 23 denotes a connecting portion, which integrally connects the plane portion 21 and the plane portion 22 above and below. Reference numeral 24 denotes a pressing portion, and a pin 26 is implanted in the center of its upper and lower surfaces 25, and the pin 26 is fitted into a hole 27 of the connecting portion 23, so that it is rotatable. 28 is the joint part 23 (or plane part 21 or 22) and the pressing part 2
4 is a spring tensioned between the pressing part 2
4 is biased clockwise in the figure. Reference numeral 29 denotes a stopper, which locks the pressing portion 24 biased by the spring 28 in a predetermined position when not in use. 3
Reference numeral 1 designates a guide fixed to the flat part 21 or 22, which forms a space 32 between the guide and the flat part 21 or 22, and the band 3 inserted through the space 32
Its position is regulated so that it does not come into contact with 9.
Reference numeral 33 denotes a corrugated portion formed at a position of the pressing portion 24 that comes into contact with the belt 3.

To explain its usage, first, the belt 3 is inserted into the belt stop of pants, for example. Next, attach the left end of the belt 3 to the flat part 2 of the buckle 1.
1 and its guide 31
Insert it into the inside of 2. When the belt 3 is pushed further when the end portion contacts the pressing portion 24, the pressing portion 24 rotates counterclockwise against the biasing force of the spring 28. The end of the belt 3 is further inserted into the space 32 on the opposite side (right side) of the flat part 21 and sent out to a desired position.

Next, in the same manner, the right end of the belt 3 is inserted into the space 32 on the plane part 22 side. At this time as well, the pressing portion 24 is pressed by the end of the belt 3 and rotates counterclockwise. When the ends of the belt 3 are fed into the specified position, grasp both ends and pull them slightly so that they wrap further around the body, then release your hands. Then, the belt 3 tries to return to the direction in which it is released from being wrapped around the body. That is, the belt 3 moves slightly in the direction indicated by the arrow in FIG. Since the pressing portion 24 is biased clockwise by the spring 28, its corrugated portion 33 is pressed against the surface of the belt 3. Therefore, a frictional force is generated between the corrugated portion 33 and the belt 3, and a rotational moment is generated in the pressing portion 24 due to this frictional force. As a result, the pressing portion 24 rotates clockwise. When the pressing part 24 rotates clockwise, the corrugated part 33 and the flat part 2 of the pressing part 24
1 and 22, the belt 3 is configured so that the distance between the pressing part 24 and the flat parts 21 and 2 is small.
It is pressed and held between 2 and 2. The cross-sectional shape of the corrugated portion 33 does not necessarily have to be a corrugated shape, and may be selected to provide a desired frictional force, but it is preferable to select a cross-sectional shape that does not damage the belt 3 as much as possible. Therefore, although the spring 28 is not necessarily necessary in principle, it is preferable to increase the frictional force by the biasing force of the spring 28, and to make the shape of the waveform portion 33 less sharp.

When removing the belt 3, the belt 3 is once pulled in the direction of being wound more tightly, and the pressing part 24 is rotated counterclockwise. Then, the belt 3 is pulled out without generating a large frictional force.

With this configuration of the buckle 1, there is no need to cut the belt 3 at a predetermined position. Therefore, even if the user gains weight or loses weight, the length can be adjusted without making any changes to the belt 3. In addition, since the buckle 1 becomes plane symmetrical when the flat parts 21 and 22 are formed into a flat shape, the flat part 21
It is also possible to use it facing outward (with the plane portion 22 facing inside). Therefore, for example, the flat parts 21, 2
2 and the front and back sides of the belt 3 can be bound in such a way that they can be used reversibly, making four types of combinations possible.

Furthermore, as shown in FIG. 7b, it is also possible to use a belt 3 with one end cut off and the other end neatly bound, but in this case, the cut side is always It will have to be used on the human body. When a belt is used in the same position for a long time, it becomes plastically deformed. Therefore, as shown in Fig. 7a, it is recommended to use a belt with both ends neatly bound and to change the position (direction) at which it is used (pressed by the pressing part 24) at any time to prevent plastic deterioration. preferable. This also increases the amount of time the belt can be used.

FIG. 4 represents another embodiment of the invention. In the embodiment shown in FIGS. 1 and 2, a pressing part 24 that presses the belt 3 toward the flat part 21 and a flat part 22
Although the pressing portion 24 that presses toward the side is integrally formed, in this embodiment, it is formed independently. With this configuration, the buckle 1
It becomes possible to make the thickness even thinner. Furthermore, in the previous embodiment, when one end of the belt 3 is detached from the buckle 1, the other end is also detached, but in this embodiment, the detachment can be performed independently of each other. .

FIG. 5 shows that the first two embodiments have flat parts 21 and 2.
2 shows an embodiment in which the belts 3 inserted between the belts 2 are pressed one by one, whereas the two belts 3 are pressed together. This embodiment is also suitable for achieving further reduction in thickness.

In the above embodiment, the pressing part 24 is the flat part 2.
1 and 22 are configured independently, but in Figure 6,
This shows an embodiment in which a pressing portion 24 (waveform portion 33) is integrally formed with the flat portions 21 and 22. In this embodiment, the flat parts 21 and 22 and the connecting part 2
3 are rotatably connected via a shaft 41,
The plane portion 21 and the plane portion 22 are configured to be able to move in parallel and change their positions with respect to each other.

In this case, the plane part 22 is translated in parallel until the coupling part 23 becomes substantially perpendicular to the plane part 21. At this time, the distance between the flat parts 21 and 22 becomes the longest, making it easier to insert the belt 3 (FIG. 6b).
After both ends of the belt 3 are inserted between the flat part 21 and the flat part 22, the flat part 22 is moved to the right in the figure, and the pressing part 24 (corrugated part 33) is brought into contact with the surface of the belt 3. Let them come into contact with you. When the belt 3 tries to loosen in the direction shown by the arrow in the figure, the flat part 2 is loosened due to frictional force.
1 tries to move to the right, and the plane part 22 tries to move to the left. As a result, the distance between the two becomes shorter and shorter, and the belt 3 is pressed and held between the two. In order to make the frictional force more sufficient, a spring (not shown) may be used to urge the coupling part 23 to rotate clockwise about the shaft 41 of the flat part 21 or 22.

In this embodiment, not only the thickness can be reduced, but also the structure can be simplified.

FIG. 8 shows yet another embodiment. In this embodiment, a flange portion 51 is provided on the plane portion 22.
A pin 53 of the first pressing portion 24A is inserted into the hole 52 of the flange portion 51, and the first pressing portion 24A is rotatable with respect to the flat portion 22. Further, the pin 54 of the flat part 21 is connected to the first pressing part 2.
It is inserted into a hole 55 formed on the opposite side of the pin 53 of 4A, and the plane part 21 is rotatable with respect to the first pressing part 24A. That is, in this embodiment, the hole 52, pin 53, hole 55, and pin 54 constitute a joint portion. A flange portion 57 having a notch portion 56 is formed on the plane portion 21,
The second pressing portion 24B having a locking portion 58 thereon is removably attached. The second pressing part 24B has one side rotatably connected to the flat part 21,
Only the other side may be locked to the flat part 21.

When in use, first the second pressing part 24B is removed from the flat part 21, and one end of the belt 3 is inserted into the flat part 21. When the belt 3 is inserted to a predetermined position, the second pressing portion 24B is inserted into the notch 56.
Press it in the direction of the flat part 21 so that it is positioned at . Then, the second pressing portion 24B is elastically deformed, and its locking portion 58 is locked to the back side of the flat portion 21. In this state, the belt 3 is pressed and held between the second pressing part 24B and the flat part 21,
Fixed. Next, the other end of the belt 3 is inserted into the space formed between the one end of the belt 3 and the flat part 22. When the other end of the belt 3 is pulled a little further and then released, the belt 3 tries to return in the direction of the arrow in the figure. At this time, the pressing portion 24A rotates clockwise in the figure due to the frictional force between the corrugated portion 33 of the pressing portion 24A and the belt 3. As a result, the belt 3 is pressed and held between the pressing portion 24A and the flat portion 22, and is fixed. In this embodiment, one end of the belt 3 is always securely attached to the buckle 1.
This improves operability.

The present invention can also be applied to cases such as supporting wristwatches.

〔effect〕

As described above, in the present invention, in the buckle, both ends of the belt are inserted between the first flat part and the second flat part, and the first pressing part is pressed against the first flat part. Since the belt is locked by bringing the second pressing part close to the second flat part, there is no need to process the belt for locking, and there is almost no need to process the belt for locking. All belts can be used. In addition, the length from the buckle to the end placed on the side that contacts the human body is increased, and
Even a long belt can be used in a fashionable manner by making the length to the end disposed on the side not in contact with the human body short. Therefore, the length can be adjusted without making any changes to the belt, not only when you lose weight but also when you gain weight.
