Description

  The present invention relates to a belt that is worn around a waist by construction workers, police officers, riot personnel, and the like.

  As a conventional rugged belt, as disclosed in Japanese Patent Application Laid-Open No. H10-260707, there is a hook that is attached to a hook formed on a buckle (hardware) by hanging a buckle hardware (hardware) on a belt tail end. That is, as shown in FIG. 1, the conventional waist belt 1 is provided with a metal buckle 3 and a buckle hardware 5 on a strong belt 2 such as cowhide. The buckle 3 includes a gate-shaped guide portion 6 on the right side of the back surface of the surface plate 4 and a clamping portion 7 on the left side. The guide portion 6 is provided with two hooks 8 projecting toward the distal end side in parallel on the distal end side thereof, and the buckle 5 is engaged with this. The sandwiching portion 7 includes an upper and lower shaft support portion 9 and a sandwiching piece 10 pivotally supported between the upper and lower shaft support portions 9. The clamping piece 10 presses the belt 2 between the back surface 4 of the buckle 3 by a turning operation, and fixes the buckle 3 and the belt 2 by the frictional force. Its structure and function are well known. The buckle 5 is fixed to the rear end of the belt 2 by caulking and can be engaged with the hook 8 (FIG. 2). A structure for this engagement is also disclosed in Patent Document 1.

  By the way, the waist belt that can no longer be used needs to be separated into a metal part and a leather part in consideration of the environment upon disposal. However, even if the buckle 3 can be easily removed from the conventional waist belt 1, the buckle metal 5 is firmly fixed to the belt 2 by the caulking hook 11, so that it is not easy to remove from the belt 2.

  The belt is attached to the buckle metal with a pin body that can be freely inserted through the buckle metal and the end of the belt inserted into the slit of the buckle metal. The pin body is provided with a shaft and a coil spring, and the shaft is moved in the axial direction and rotated to disengage the pin body from the buckle metal. The pin body which has been disengaged from the buckle metal is removed, and then the belt end is removed from the slit of the buckle metal.

  FIG. 3 shows an attachment point between the buckle metal 5 and the belt 2 end according to the present invention. The other structure is the same as that of the conventional waist belt 1 shown in FIG.

  The buckle metal 5 is made of brass having a horizontal dimension of 25 mm, a vertical dimension of 42 mm, and a front and back dimension of 9 mm, and has an engaging portion 12 that is hooked on the hook 8 of the buckle 3 on the left (rear side) and the right (front side). Has a slit 13. The slit 13 has a depth of 14 mm from the right end surface to the left, and a front-back direction dimension of 5.5 mm. The slit 13 is open at the right end and penetrates in the vertical direction. That is, it is formed of a front wall 14 and a back wall 15 having a thickness of 1.75 mm (the back side is visible in FIG. 3).

The structure of the engaging portion 12 is the same as that of the conventional example. The protruding portion of the engaging bar 16 protruding downward from the lower surface of the buckle metal 5 is pushed into engagement with the hook 8, and the hook 8 is released by releasing the pushing. Engagement is completed while preventing slipping out of
The front wall 14 of the buckle 5 is formed with two bottomed holes 17, 17 on the top and bottom, and the vertical wall 18 and the lateral hole 19 are perpendicular to the center of the back wall 15 (FIG. 4). Two cross-shaped holes / grooves 20 are formed on the upper and lower sides. The edge-bottomed hole 17 and the cross-shaped hole / groove 20 are formed coaxially along an axis penetrating in the front-back direction. The specific structure of the pair of the vertical hole 18 and the horizontal hole 19 will be described in order later.

  Reference numeral 21 denotes a pin body, which is composed of a shaft metal 22, a coil spring 23, a washer 24, and a cylindrical spacer 25 arranged coaxially. The shaft 22 is made of steel and is composed of a shaft portion 26 and a T-shaped portion 28 having an engagement portion 27 protruding left and right at the tip thereof. The T-shaped portion 28 can penetrate the longitudinal hole 18 in the front and back direction, although the engagement portion 27 protrudes from the left and right. That is, the vertical dimension and width of the vertical hole 18 are sufficiently larger than the T-shaped portion 28 (FIG. 5). Further, the horizontal hole 19 penetrates only the portion overlapping the central vertical hole 18, and both sides are stepped portions 29. That is, when the T-shaped portion 28 penetrating the vertical hole 18 to the back side is rotated by 90 °, the T-shaped portion 28 cannot pass through the vertical hole 18 and engages with the step portion 29 of the horizontal hole 19. .

The coil spring 23 can also penetrate the cylindrical spacer 25, and is sufficiently longer than the axial dimension of the cylindrical spacer 25 in a free state as shown in FIG.
In this embodiment, the washer 24 has a pan head wind that is raised on the front side, and is formed with a hole 30 and a tool hook portion 31 through which the shaft portion 26 of the shaft 22 passes (FIG. 7). Here, the hole 17 with the edge bottom is smaller than the washer 24 at the bottom, and an insertion hole 32 equal to the inner diameter of the cylindrical spacer 25 is formed. The large-diameter portion on the outside of the hole 17 with the edge bottom has a size that allows the washer 24 to be fitted.
The cylindrical spacer 25 is a stainless steel short cylinder, and its axial length is equal to or slightly shorter than the front and back dimension of the slit 13.

  The pin body 21 is assembled as follows (FIG. 6). A coil spring 23 is fitted to the shaft portion 26 of the shaft metal 22 and a washer 24 is further fitted to the shaft portion 26 (FIG. 6A). Next, the tip of the shaft portion 26 protruding from the washer 24 is caulked to prevent the washer 24 from coming off. And Thereby, the washer 24 and the coil spring 23 are attached to the shaft 22 to form the pin body 21 (FIG. 6B). In this state, the coil spring 23 is in a free state with the T-shaped portion 28 of the shaft 22 in this embodiment. The pin body 21 is in a normal state where the shaft 22 is not operated, and the T-shaped portion 28 is brought into contact with the step portion 29 of the lateral hole 19 as shown in FIG. The space S in which the T-shaped portion 28 is pushed out from the lateral hole 19 to the back side is left between the washer 24 and the edge bottom 33 so that the space S can be released. The coil spring 23 is lightly compressed between the inner surface of the back wall 15 and the back surface of the washer 24.

Attachment of the buckle 5 and the belt 2 end is performed as follows.
The cylindrical spacer 25 is fitted into the through hole 34 (FIG. 3) formed at the end of the belt 2. The position of the through hole 34 is adjusted to the position of the hole 17 with the edge bottom in the buckle 5. The end of the belt 2 is inserted into the slit 13 of the buckle 5 together with the cylindrical spacer 25, the cylindrical spacer 25 is aligned with the axis of the hole 17 with the bottom edge and the longitudinal hole 18, and the pin body 21 from the side of the hole 17 with the edge bottom. Is inserted into the cylindrical spacer 25 with the T-shaped portion 28 at the top. Further, the washer 24 is pressed to compress the coil spring 23, and the T-shaped portion 28 is first pushed out from the longitudinal hole 18 to the back side of the buckle 5 and then rotated to engage the T-shaped portion 28 with the lateral hole 19, Fixed axial movement. The combined state is shown in FIG.

  The pin body 21 passed through the through hole 34 at the end of the belt 2 reliably engages with the buckle 5 and withstands the force in the pulling direction applied to the belt 2. At this time, in the pin body 21, the T-shaped portion 28 of the shaft 22 is engaged with the lateral hole 19 of the buckle metal 5, while the coil spring 23 projects the washer 24 outward based on the inner surface of the back wall 15. Therefore, the pin body 21 does not rattle or come off. For this reason, the waist belt 1 can be used safely and stably. In this embodiment, the cylindrical spacer 25 is used, and the load acting on the belt 2 is dispersed at the position of the through hole 34, so that the durability is also high.

  In order to separate the buckle metal 5 from the state in which the buckle metal 5 is attached to the end of the belt 2 (FIG. 8A), first the shaft 22 and the bottom surface of the washer 24 are the bottom of the hole 17 with the edge bottom. The space S is pushed up to 32, and the T-shaped portion 28 at the tip of the shaft 22 is floated from the lateral hole 19 provided in the wall 15 on the back side of the buckle 5 (axial movement of the pin body 1, FIG. 8B). Next, the T-shaped portion 28 is rotated by 90 ° as it is, so that the position corresponding to the horizontal hole 19 is changed to the position corresponding to the vertical hole 18 (rotation around the axis, FIG. 8C). Then, the T-shaped portion 28 passes through the longitudinal hole 18 to the front side, thereby passing through the cylindrical spacer 25 together with the coil spring 23, so that the entire pin body 21 can be extracted from the end of the buckle metal 5 and the belt 2.

Next, the end of the belt 2 is pulled out from the slit 13 of the buckle metal 5 and the buckle metal 5 and the belt 2 are separated. The cylindrical spacer 25 remains in the through hole 34 at the end of the belt 2 that has been pulled out, but it is easy to separate it.
If the coil spring 23 is made strong for the sake of safety, the axial movement and rotation around the axis will be difficult only with the fingertips. In this case, a simple tool such as a screwdriver or pliers is used. Even so, it can be said that it can be separated very easily compared to releasing the fixing with the caulking ridge.

Thus, one embodiment has been described.
The cylindrical spacer 25 is preferably used, but is not essential in the present application.
As a means for preventing the shaft portion 26 of the shaft 22 and the washer 24 from coming off, caulking at the tip of the shaft portion 26 is used, but means for welding or screwing another retaining member may be considered.
The T-shaped portion 28 of the shaft 22 may also be a combination of two members.
The forms of the washer 24 and the T-shaped portion 28 are not limited to the illustrated specific configuration as long as they have the same function of engaging and disengaging.
