2. Description of the Related Art As shown in FIG.
It is provided with a rectangular frame body 72, a fastener 71 that holds the rear end portion of the belt body 4, and a pin member 73 that is inserted into the belt hole 41 of the belt body 4.

The fastener 71 comprises an upper plate 711 and a lower plate 712, and the frame body 72 is attached to the lower plate 712. Upper plate 711
Are pivotally connected to the lower plate 712 at both ends of the rear portion, and the upper plate 711 is configured to be openable and closable.
In addition, engaging pieces 711 are provided on both side ends of the upper plate 711.
2 is provided in a protruding manner, and when the upper plate 711 is tilted and closed, the engaging pieces 7112 are engaged with the respective side end portions of the lower plate 712. Therefore, the fastener 7
When the rear end of the belt body 4 is inserted between the upper plate 711 and the lower plate 712 from the rear of the upper plate 711 and the upper plate 711 is tilted and closed, the upper plate 71
The toothed biting piece 7114 formed at the rear part of the biting 1 bites into the belt body 4. In this way the fastener 7
The rear end portion of the belt body 4 is connected to 1. In addition, the front rail portion of the frame body 72 has projections 7211, 7 provided on each horizontal rail portion.

[0004]

By the way, when the belt provided with the buckle is attached to, for example, a baseball uniform, the rear end of the belt body 4 is fastened when the buckle is subjected to a severe impact due to head sliding or the like. There is a problem that the belt is detached from the pin 71 or the pin member 73 comes out from the belt hole. This is due to the following reasons.

That is, the fastener 71 is of an upper opening type in which the upper plate 711 is opened and closed. Therefore, when the buckle receives a heavy impact from the ground during head sliding, the upper plate 711 rises and opens, and the fastener 71 is opened. This is because the rear end of the belt body 4 comes off. Further, since the pin head of the pin member 73 projects from the upper surface of the frame body 72, the pin head is caught on the ground and the pin member 73 comes out of the belt hole 41, and the tip end side of the belt body 4 comes out of the frame body 72. It depends on that it comes off.

Further, the impact received by the pin member 73 is transmitted to the roller member 721 which is the front bar portion, the cylindrical body 7212 of the pin member 73 falls off the projections 7211 and 7211, and the tip end side of the belt body 4 is separated from the frame body 72. It rarely slipped out. The present invention relates to “a rear end of a belt main body is held by a fastener composed of upper and lower two plates, and a tip end side of the belt main body is inserted into a frame body attached to a front portion of the fastener. In the belt buckle that locks the belt by passing the pin member attached to the frame through the belt hole,
The task is to prevent the belt from being easily released from the belt even if the buckle receives a heavy impact.

[0007]

[Means for Solving the Problems] Technical means taken to solve the above problems are as follows. "The fastener is configured such that the two plates are connected to each other at both ends of the rear portion, and the frame body is extended forward at the front end portion of the upper plate so that the lower plate can be opened and closed. Upper side engaging portions are provided at both side ends and a front end portion of the upper plate, and lower side engaging portions that engage with the upper side engaging portions are provided at both side end portions and a front end portion of the lower plate, respectively. I set it up separately. It is preferable that the upper engaging portion and the lower engaging portion are provided at a total of four places, one at each side end and two at both ends of the front end.

The above technical means act as follows.
When the lower plate of the fastener is raised with the rear portion as a fulcrum and the front portion as an action point, and the engagement state with the upper plate is released, the pinching of the rear end portion of the belt main body is released and the belt main body is released from the fastener. Removed. That is, the belt body is structured so as not to come off the fastener unless the lower plate is raised and opened. Therefore, since the lower plate is pressed against the abdomen when the belt is worn, the lower plate does not rise and open even when the buckle is impacted when the belt is worn.

Since the upper plate and the lower plate are engaged with each other by the upper engaging portion and the lower engaging portion,
With respect to the impact from the side of the buckle, the engaging force of the upper engaging portion and the lower engaging portion at both end portions suppresses the rising of the lower plate, and with respect to the impact from the front and rear direction of the buckle. In particular, the rising force of the lower plate is suppressed by the engaging force of the upper engaging portion and the lower engaging portion at the front end portion.

In the above-mentioned technical means, "a cylindrical body is inserted in the vicinity of the front rail portion in the frame body through a shaft portion which is bridged between both lateral rail portions of the frame body so as to be parallel to the front rail portion. The arranged roller member is provided, and the roller member is set at a position where the pin head of the pin member is just caught, and its height is lower than the thickness of the pin head from the upper surface of the frame body. In the belt mounting, the tip of the belt body is passed from the inside of the roller member, the pin member is inserted into the belt hole, and the pin head is brought into contact with the roller member. The roller member has a configuration in which a cylindrical body is inserted through a shaft portion that is bridged between both horizontal rail portions of the frame body, and since the shaft portion is inserted through the entire area of the cylindrical body, the roller member in the state where the belt is attached is Even if the roller member receives an impact, the cylindrical body does not drop off from the frame body. Moreover, since the height of the roller member is set to a position lower than the thickness of the pin head from the upper surface of the frame body, the pin head does not project from the upper surface of the frame body even when the belt is mounted. Therefore, even if an obstacle slides on the upper surface of the frame, the frame does not act as a guard and the pin head does not come into direct contact with the obstacle. Therefore, the pin head is caught by the obstacle and falls out of the belt hole. Nothing.

In the above-mentioned technical means, "a projecting piece arranged in the frame is extended to a front end portion of the lower plate", and the lower plate is pushed upward by pushing the projecting piece from above. It can be easily disengaged from the plate. Also, since the protrusion is arranged in the frame,
The frame serves as a guard so that the projecting piece is not impacted. Further, since the protruding piece can be seen when the belt is not attached, a logo mark or the like can be displayed on the protruding piece to change the appearance.

[0012]

As described above, according to the present invention, since the lower plate does not rise and does not open when the belt is attached, even if the buckle is impacted, the belt body may come off from the fastener or the buckle may be disassembled. There is nothing to do. Further, with the roller member provided in the frame body, the pin member does not come out of the belt hole and the belt body is not unmounted. Furthermore, according to the protrusion extending on the front end of the lower plate, the lower plate can be easily disengaged, and a logo mark or the like can be displayed on the protrusion to change the appearance. You can also

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to FIGS. The belt buckle according to this embodiment is used as a belt for sports clothes, particularly a baseball uniform, but may be used for general clothing.

As shown in FIG. 1, the buckle includes a fastener 1 that holds a rear end portion of a belt body 4, a rectangular frame 2 attached to the fastener 1, and the frame 2. And a pin member 3 disposed therein. Further, a patch member 5 is arranged under the buckle to prevent the buckle from rubbing and damaging the clothes when the belt is worn. The patch 5 is fixed to the lower plate 12 of the fastener 1 by rivets R or the like (see FIG. 5). Then, when mounting the belt, the belt main body 4 is passed through the belt passing portion of the pants, and the tip end side of the belt main body 4 is applied to the hole portion 5 of the patch 5.
1 is passed through the frame body 2 from below and the pin member 3 is held in the belt hole 41 at a predetermined length.

The fastener 1 will be described. The fastener 1 is composed of two plates 11 and 12 arranged vertically. Then, the upper plate 11 and the lower plate 12 are provided with flange portions 1 at both ends of the rear portion.
14 and 124 are formed, and the flange portions 114 and 124 are formed.
Each other is pivotally supported. As a result, the upper plate 11 and the lower plate 12 are connected. In addition, the frame body 2
Are attached to the upper plate 11. This attachment is performed by bending the front portion 111 of the upper plate 11 downward into a hook shape and loosely fitting the rear frame portion 24 of the frame body 2. The hook-shaped front portion 111 is notched at the center thereof so as not to interfere with the arrangement of the pin member 3 on the frame body 2. Also, the upper plate 1
A belt member 6 is wound around the belt member 1 with play, and the belt member 6 is inserted and held at the front end side of the belt body 4 inserted from inside the frame 2. On the other hand, the front part of the lower plate 12 is in a free state. Therefore, the lower plate 12 can be opened and closed with both ends of the rear part connected to the upper plate 11 as fulcrums.

The upper plate 11 is provided with upper engaging portions 112 and 113 at four positions, one at each of both end portions of the upper plate 11 and at both ends of the front end portion (see FIG. 3). ). Also on the lower plate 12, the upper engaging portion 1 is provided at four locations corresponding to the upper engaging portions 112 and 113.
Lower engaging portions 122 and 123 that engage with 12, 113 are provided (see FIG. 3). The upper engaging portion 11
Reference numerals 2 and 113 each include a protruding piece extending downward from each end, and the lower portion of the protruding piece is bent into a dogleg shape. The one upper side engaging portion 113 provided at the side end is
The V-shaped bent portion has a shape projecting inward, and the other upper engaging portion 112 provided at the front end portion is set to have a shape in which the V-shaped bent portion projects forward.

The lower engaging portion 123 of one side end of the lower engaging portions 122 and 123 is formed by folding a part of the lower plate 12, and the lower engaging portion of the other front end portion. The joining portion 122 is composed of a protruding piece extending upward. And
When the lower plate 12 is brought closer to the upper plate 11 side, the dogleg-shaped bent portions of the upper engaging portions 112, 113 mesh with and engage with the lower engaging portions 122, 123, whereby the lower plate 12 is closed. At this time, the rear end of the belt body 4 is attached to the upper plate 1 from the rear of the fastener 1.
1 is inserted between the lower plate 12 and the lower plate 12, a jagged end piece 124 (see FIG. 4) formed on the rear portion of the lower plate 12 is caught in the belt body 4, and Then, the rear end of the belt body 4 is connected to the fastener 1. Since both ends of the rear portion of the fastener 1 provided with the engaging piece 124 are pivotally supported, the lower plate 12 does not open even if the belt body 4 is pulled in the pulling direction. Then, when the lower plate 12 is raised with the rear part as a fulcrum and the front part as an action point and the engagement state with the upper plate 11 is released, the jagged engagement piece 124 at the rear part of the lower plate 12 causes the belt main body 4 to move. Get out of the belt body 4
The clamping at the rear end is released. In this state, the belt body 4 can be pulled out from the fastener 1 and removed. That is, the belt body 4 is structured so as not to come off from the fastener 1 unless the lower plate 12 is raised and opened. Therefore, since the lower plate 12 is pressed by the abdomen when the belt is worn, the lower plate 12 does not rise and open. Moreover, the upper plate 11 and the lower plate 12 are connected to each other by the upper engaging portions 112, 113 and the lower engaging portion 122, respectively.
Since it is engaged with 123, the rising force of the lower plate 12 is suppressed by the engaging force of the upper engaging portion 113 and the lower engaging portion 123 at the both end portions against the impact from the side of the buckle. It Further, with respect to the impact from the front-back direction of the buckle, the engaging force of the upper engaging portion 112 and the lower engaging portion 122 at the front end portion restrains the lower plate 12 from rising. As a result, when the belt is worn, the lower plate 12 does not rise and open even if the buckle receives an impact from the ground due to head sliding or the like. Therefore, even if the buckle receives an impact, the rear end of the belt body 4 does not come off from the fastener 1 and the buckle does not disassemble.

At the front end of the lower plate 12, a projecting piece 120 arranged inside the frame 2 is extended (see FIG. 2). Therefore, the lower plate 12 can be easily disengaged from the upper plate 11 by pushing the protrusion 120 from above. Further, since the projecting piece 120 is arranged in the frame body 2, the frame body 2 serves as a guard and the projecting piece 120 is not impacted. Further, since the protrusion 120 can be seen when the belt is not attached, a logo mark or the like can be displayed on the protrusion 120 to change the appearance.

The frame 2 will be described. The frame 2
Is formed in a rectangular shape as a whole, and includes a front rail portion 23, horizontal rail portions 22a and 22b, and a rear frame portion 24 (see FIG. 1).
See. ). The fastener 1 is attached to the rear frame portion 24, and the pin member 3 is rotatably attached to the central portion thereof. In addition, in the frame body 2, the front rail portion 2
The roller member 21 arranged in the vicinity of 3 in parallel with the front rail 23
Is provided. The roller member 21 has a configuration in which a cylindrical body 212 is inserted into a shaft portion 211 that is bridged between the horizontal crosspiece portions 22a and 22b of the frame body 2. The roller member 21 is set at a position where the pin head 30 of the pin member 3 is just caught. The height of the roller member 21 is set to a position lower than the thickness of the pin head 30 from the upper surface 20 of the frame body 2. When mounting the belt, the front end of the belt body 4 is passed from the inside of the roller member 21, the pin member 3 is inserted into the belt hole 41, and the pin head 30 is brought into contact with the roller member 21 (see FIG. See 5). As described above, the roller member 21 includes the shaft portion 211 that is bridged between the horizontal rail portions 22 a and 22 b of the frame body 2.
The cylindrical body 212 is inserted into the cylindrical body 21.
Since the shaft portion 211 is inserted through the entire area of 2, even if the roller member 21 receives an impact in the belt mounted state,
The cylindrical body 212 does not fall off the frame body 2. In addition, since the height of the roller member 21 is set to a position lower than the thickness of the pin head 30 from the upper surface 20 of the frame body 2, the pin head 30 is set to the upper surface 2 of the frame body 2 even when the belt is worn.
Does not stick out from 0. Therefore, for example, even when the head is sliding, the frame body 2 serves as a guard and the pin head 30 does not come into direct contact with the ground.
Does not fall off the belt hole 41 due to being caught on the ground. Therefore, the pin member 3 does not slip out of the belt hole 41 and the belt body 4 is not detached.

The belt body 4 will be described. As shown in FIG. 6, the belt main body 4 has a substantially arcuate shape in which a flat truncated cone-shaped tube is developed in a planar shape in a stretched state. In addition, the substantially central region of the belt body 4 is formed wide to form a support portion 42, and a range from both sides of the support portion 42 to both ends of the belt body 4 is a narrow strip portion 43 thinner than the support portion 42. . The belt body 4 includes a skin material 44 constituting the front side, a back skin material 47 constituting the back side, and a first core material inserted between the skin material 44 and the back skin material 47 over substantially the entire area. 45 and a second core material 46 inserted between the first core material 45 and the backing material 47 in the support portion 42.

As a result, when the belt is worn, the support portion 42, which is wider than the narrow strip portions 43 on both sides and has a quadruple structure to increase strength and hardness, is positioned on the waist portion side. Protects even more reliably. Further, since the second core member 46 is inserted between the first core member 45 and the backing member 47 and protrudes toward the inner side of the belt body 4, the waist portion is the second core member. It is more effectively supported by the core material 46. on the other hand,
The thin strip portion 43 located on the abdominal side has a triple structure, and is thicker and harder than a normal men's belt. Therefore, even if it is used for a long period of time, the belt is curled in the vertical direction and the belt hole 41. There is no inconvenience that the pin is damaged by the pin member 3 of the fastener 1. Also, when the belt is wound in an annular shape, it is designed so that it has a substantially truncated cone shape, so it fits snugly to the body that has the same three-dimensional shape, is comfortable to tighten, and the support part 42 is tight on the waist. Since it can be attached in a manner that follows, the support effect is improved.

As described above, according to the buckle of the above-described embodiment, the lower plate 12 does not rise and open when the belt is attached, so that the belt body 4 can be detached from the fastener 1 even if the buckle receives an impact. Also, the buckle does not disassemble. Further, since the roller member 21 is provided in the frame body 2, the pin member 3 is attached to the belt hole 41.
There is no possibility that the belt body 4 will be unattached after being pulled out.

Further, the protruding piece 1 is attached to the front end of the lower plate 12.
Since 20 is extended, the lower plate 12 can be easily disengaged, and a logo mark or the like can be displayed on the protrusion 120 to change the appearance. Further, the waist effect can be obtained by the belt body 4. The engaging portions 112, 113, 122, 1 of the fastener 1 are
23 are provided at four places on the upper plate 11 and the lower plate 12, but any number may be provided.
