Description

  The present invention relates to a belt buckle used for a reversible belt having different designs on both sides of the belt.

  FIG. 6 shows a perspective view of a conventional general belt buckle 1, in which a belt 4 made of leather or the like is attached to a support shaft 3 provided on a metal frame 2. After the belt 4 is wound around the user's abdomen, the tip of the belt 4 (not shown) is passed through the frame 2, and the support shaft 3 is attached to any one of a plurality of belt holes provided at the tip of the belt 4. The belt 4 is hooked at a predetermined length by inserting a metal pin member 5 that is pivotably attached to the belt 4. In this case, the pin member 5 is curved in a substantially S-shape, and the tip portion thereof is formed so as to be easily inserted into the belt hole and to fit into the pin receiving recess 6 provided in the frame 2.

  However, the buckle 1 is manufactured on the premise that only the A surface which is one side of the belt 4 is used as the outer surface. As shown in FIG. 7, when the front and back of the belt 4 are reversed and the B surface is used as the outer surface, the bending of the tip of the pin member 5 is also reversed, and the tip of the pin member 5 is locked. The pin receiving recess 6 can no longer be used, and is inconvenient.

  Even if the pin receiving recess 6 can be solved by forming it on both sides of the frame 2, the bending direction of the tip of the pin member 5 is large in convenience when the pin member 5 is inserted into the belt hole of the belt 4. affect. Also, the bent pin member 5 as shown in FIG. 7 is difficult to insert into the belt hole of the belt 4 even if the pin receiving recess 6 is provided at this position.

  In order to solve this problem, Patent Document 1 discloses a buckle for a reversible belt that can be used on both sides of the belt.

  However, the buckle in Patent Document 1 must be disassembled by reassembling the buckle every time the surface used by the belt is changed, and the work is troublesome, and the parts are lost when disassembled. There is also a risk of doing.

  An object of the present invention is to provide a belt buckle that can solve the above-described problems and can arbitrarily use both sides of the belt without disassembling the buckle.

  A belt buckle according to the present invention for achieving the above object is characterized in that a support shaft for fixing a belt is stretched around the center of a frame, a support ring is rotatably attached to the support shaft, and the pin has a curved shape. The member is arranged in a direction orthogonal to the support shaft, and a rear end portion of the pin member is rotatably attached to the support ring.

  According to the buckle for a belt according to the present invention, the belt can be reversible and either one of both sides can be easily selected and used.

It is a perspective view of the buckle for belts of an Example. It is a disassembled perspective view of a support ring and a pin member. It is a perspective view of the state which connected the pin member to the support ring. It is a perspective view of the state which made the surface of the belt the outside. It is a perspective view of the state which made the back of the belt the outside. It is a perspective view of the conventional buckle. It is a perspective view of the conventional buckle.

The present invention will be described in detail based on the embodiment shown in FIGS.
FIG. 1 is a perspective view of a metal belt buckle 11 that can be used for a reversible belt in the embodiment. A support shaft 13 for fixing the belt is disposed at the center of the frame 12 having a square frame, and the shape of the “day” is set to be horizontal. The frame 12 and the support shaft 13 are manufactured by integrally molding with a casting or fixing separately manufactured parts by welding or the like. Note that the frame 12 is not a square frame, and there is no problem even if it is a circular frame or an oval frame. Moreover, you may provide a cut | interruption partially in the flame | frame 12 of a frame.

  A support ring 14 is rotatably inserted into the support shaft 13. Further, the support ring 14 serves as a clasp for the belt hole, and a rear end portion 15 a of a pin member 15 having a substantially S-shaped curved shape is provided. The pin member 15 is attached in a direction orthogonal to the support shaft 13. Further, pin receiving recesses 12a and 12b are formed at positions on both sides of the frame 12 with which the tip 15b of the pin member 15 abuts when the support ring 14 rotates.

  FIG. 2 is an exploded perspective view of the support ring 14 and the pin member 15. The support ring 14 is manufactured by cutting the slit 14a in the longitudinal direction of the metal pipe, and then cutting the metal pipe into a predetermined length in a ring shape. Further, the slit 14a is expanded to form a substantially C-ring, and a hole 14b having a predetermined cross-sectional diameter is drilled on the opposite side of the slit 14a. The hole portion 14b is often made larger than the diameter of the rear end portion 15a of the pin member 15.

  An annular groove 15c is formed in the rear end portion 15a of the pin member 15 by cutting, and then the pin member 15 is bent in a substantially S shape toward the pin receiving recesses 12a and 12b. After the rear end portion 15a of the pin member 15 is inserted into the hole portion 14b of the support ring 14 and disposed on the pin member 15 so that the annular groove 15c is positioned at the edge portion of the hole portion 14b, the hole portion 14b is shown in FIG. As shown, when pressed from the up and down direction indicated by the arrow, the hole 14b having a perfect circular shape becomes an elliptical shape crushed in the up and down direction.

  Thus, the upper and lower edges of the elliptical hole portion 14b are fitted into the annular groove 15c of the pin member 15, and the pin member 15 does not come out of the support ring 14 and can be rotated around the annular groove 15c. Connected to And after inserting the support ring 14 which connected the pin member 15 into the support shaft 13 using the slit 14a, it closes the gap | interval of the slit 14a so that it may not remove | deviate from the support shaft 13, as shown in FIG. The buckle 11 can be obtained.

  In the buckle 11, the support ring 14 can rotate 180 degrees with respect to the support shaft 13, and the pin member 15 can rotate 360 degrees with respect to the support ring 14 around the axis. Regardless of which surface of the belt is used, just by rotating the pin member 15, the tip 15b of the pin member 15 becomes a buckle 11 bent toward the pin receiving recess 12a or 12b, just like a normal belt.

  When the rear end portion 15a of the pin member 15 is inserted into the hole portion 14b of the support ring 14 and crushed, the pin member 15 is rotated with respect to the support ring 14 by adjusting the pressing force from above and below. A moderate resistance can be generated. By generating resistance in this way, the pin member 15 does not rattle with respect to the support shaft 13, and the shape can be maintained.

  In order to prevent rattling between the rear end portion 15a and the hole portion 14b, the width of the annular groove 15c is matched with the thickness of the support ring 14 to reduce rattling or the width of the annular groove 15c. If the spring washer is inserted into a part of the pin member 15 in advance, rattling of the pin member 15 is reduced by the elastic force of the spring washer.

  Then, the belt 21 is fixed to the support shaft 13 with respect to the buckle 11 as shown in FIG. Since the turn-back portion 21a of the belt 21 is inserted into the support shaft 13 and the support ring 14 is exposed from a part of the notch portion 21b of the turn-up portion 21a, the rotation of the support ring 14 with respect to the support shaft 13 is hindered. Further, the position of the support ring 14 is positioned by the notch 21b of the belt 21.

  The belt 21 is fastened to the buckle 11 by turning the belt 21 around the trousers, passing the tip portion between the frame 12 of the buckle 11 and the support shaft 13 and inserting the tip portion 15b of the pin member 15 into the belt hole. . And the front-end | tip part 15b of the pin member 15 contact | abuts to the pin receiving recessed part 12a, and the vertical position shift of the front-end | tip part 15b of the pin member 15 is prevented.

  FIG. 4 shows a case where the A surface of the belt 21 is used outside, but when the B surface is used, the belt 21 is turned upside down around the support shaft 13 as shown in FIG. Is rotated with respect to the support shaft 13 and the pin member 15 is further rotated 180 degrees to reverse the bending of the tip 15b, the tip 15b comes into contact with the pin receiving recess 12b.

  In the embodiment, the belt buckle provided with the pin receiving recesses 12a and 12b has been described. However, the pin receiving recesses 12a and 12b are not necessarily indispensable.

  In the embodiment, the manufacturing process of the buckle 11 has been described. For example, the support ring 14 is manufactured from a metal plate instead of a metal pipe. The present invention uses other means within the scope of the claims. May be manufactured.
