Abstract
Description
Technical Field
[0001] The present invention relates to a buckle for a clothing belt, and more particularly, to a buckle that can easily position the length of the belt during wearing and maintain the positioned state.
Background Art
[0002] Conventionally, as a buckle that can easily position the length of the belt during wearing, a buckle having the configuration shown in FIGS. 6 to 10 is known. This buckle 1 includes a lower holder 3 that holds the rear end portion side 2a of the belt 2 in a fixed state, a holder lid 4 that is rotatably provided at the end of the lower holder 3, a holding portion 5 that holds the front end portion side 2b of the belt 2 (see FIG. 8) inserted through the lower holder 3 from the direction of arrow A, an upper holder 7 that is supported via pipe shafts 6a on both side wall portions 6 of the lower holder 3 and can be opened and closed, a stopper member 8 that rotates via the pipe shaft 6a in conjunction with the opening and closing operation of the upper holder 7 (see arrow B in FIGS. 6, 9, and 10), and an engagement protrusion 9 provided at the central portion of the stopper member 8 (see Patent Document 1).
[0003] The engagement protrusion 9 is recessed into the step portion 10 when the upper holder 7 is in the open state (see FIG. 10), and the belt 2 can be inserted and pulled out. When the upper holder 7 is in the closed state (see FIG. 9), it protrudes above the step portion 10.
[0004] That is, as shown in FIG. 9, when the upper holder 7 is in the closed state, the engagement protrusion 9 protrudes above the step portion 10 and engages with an engagement claw 11 (see FIG. 8) formed on the back surface of the belt 2, so that the belt 2 cannot be pulled out. Also, as shown in FIG. 10, when the upper holder 7 is in the open state, the engagement protrusion 9 is recessed into the step portion 10, so that the engagement state with the engagement claw 11 is released, and the belt 2 can be inserted and pulled out.

[0005] [Patent Document 1] Utility Model Registration No. 3249272 (Publication) [Overview of the project] [Problems that the invention aims to solve]
[0006] In this conventional buckle 1, when pulling the belt 2 out of the lower mold holder 3, the lower mold holder 3 and the upper mold holder 7 are grasped together by hand, and then the upper mold holder 7 is lifted with the fingers (see Figure 10) to release the engagement between the engaging projection 9 and the engaging claw 11, and the belt 2 is then pulled out. In other words, removing belt 2 requires lifting the entire upper holder 7, which is a complex and surprisingly cumbersome operation.
[0007] Therefore, the conventional buckle 1 has a problem that needs to be solved: to make the process of pulling out the belt 2 even simpler and easier. [Means for solving the problem]
[0008] The gist of the present invention, which solves the problems of the aforementioned conventional example, is a buckle for a clothing belt that positions the length of the belt when worn and maintains that position, the buckle comprising: a frame portion having a rectangular frame body; a holder portion integrally provided with the frame portion via a connecting arm and having a storage portion at its rear end into which the rear end of the clothing belt is inserted; a substantially U-shaped belt holding portion provided on the front side of the holder portion; a holder lid provided to open and close relative to the storage portion; an inclined switch portion supported on the inside of the connecting arm via a pipe shaft and moving in an inclined state; a stopper member that rotates via the pipe shaft in conjunction with the inclined movement of the inclined switch portion; and an engaging projection provided in the center of the stopper member, wherein the engaging projection retracts into a stepped portion when the inclined switch portion is moved inclined, allowing the belt to be inserted and removed, and when the inclined switch portion is in an upright state, it protrudes above the stepped portion and engages with an engaging claw formed on the back surface of the belt, preventing the belt from being removed.
[0009] Furthermore, a spring material is provided on the stepped portion, and the spring material presses against the engaging projection, causing the engaging projection to protrude above the stepped portion; The connection portion between the frame portion and the connecting arm has a vertical wall portion, and the inclined switch portion is provided along this wall portion; The upper edge of the connecting arm has a curved portion, and the tilt switch portion tilts and moves along this curved portion; When the tilt switch section is in an upright position, a gap is formed between the lower end of the tilt switch section on the tilting direction side and the upper edge of the connecting arm; It includes. [Effects of the Invention]
[0010] According to the buckle of this invention, when the tilt switch is tilted, the engaging projection retracts into the stepped portion, allowing the belt to be inserted and removed. Furthermore, when the tilt switch is in an upright position, the engaging projection protrudes above the stepped portion and engages with the engaging claws formed on the back of the belt, preventing the belt from being removed. In other words, since the tilt switch is simply moved using just one finger, it offers the superior advantage of allowing the belt to be pulled out with a simple and easy operation compared to conventional buckles.
[0011] A spring material is placed in the stepped section, and the spring material presses against the engaging projection, causing the engaging projection to protrude above the stepped section. Normally, the pressing force of the spring material causes the engaging projection to protrude above the stepped section, resulting in an engagement state with the engaging claws formed on the back surface of the belt, thus providing the excellent effect of preventing the belt from being pulled out.
[0012] The connection between the frame and the connecting arm has a vertical wall section, and the tilt switch section is provided along this wall section. This ensures that the tilt switch section can only tilt and move in the opposite direction from the wall section, resulting in the excellent effect of allowing for accurate and simple operation of the tilt switch section.
[0013] The upper edge of the connecting arm has a curved section, and the tilt switch section moves along this curved section, resulting in smooth tilt movement of the tilt switch section and excellent stability of operation.
[0014] When the tilt switch is in an upright position, a gap is formed between the lower end of the tilt switch on the tilting direction side and the upper edge of the connecting arm. This gap allows the tilt switch to move smoothly and without hindrance, resulting in the excellent effect of stable operation. [Brief explanation of the drawing]

Embodiments for Carrying out the Invention
[0016] Next, embodiments of the present invention will be described with reference to the drawings. First, in FIGS. 1 to 5, reference numeral 21 indicates a buckle. This buckle 21 includes a frame portion 22 having a rectangular frame, a holder portion 25 integrally provided via a connecting arm 29 with the frame portion 22 and having a storage portion 24 into which a rear end portion 23a of a clothing belt 23 is inserted at the rear end, a substantially U-shaped belt holding portion 26 provided on the front side of the holder portion 25, a holder lid 28 provided so as to be openable and closable with respect to the storage portion 24, an inclined switch portion 31 supported via a pipe shaft 30 inside the connecting arm 29 and moving in an inclined state, a stopper member 32 (see FIG. 2) that rotates via the pipe shaft 30 in conjunction with the inclined movement of the inclined switch portion 31, and an engagement protrusion 33 (see FIG. 2) provided at the central portion of the stopper member 32.
[0017] As shown in Figures 1 to 3, the frame portion 22 is formed in the shape of a rectangular frame and includes a front end portion 22a and both side portions 22b. A projection 34 is provided at the center of the tip portion 22a, and the projection 34 serves both as a retainer for the belt 23 and as a decorative element. Furthermore, each of the two side portions 22b is provided with a hanging portion 35 at its tip, and a rotating pipe 37 is stretched across the hanging portion 35 with a small hole 36 inserted through it.
[0018] The holder portion 25 is integrally provided with the frame portion 22 via a connecting arm 29, and has a storage portion 24 at its rear end into which the rear end portion 23a of the clothing belt 23 is inserted (see Figure 1). Furthermore, as shown in Figure 2, a stepped portion 38 is formed at the tip of the holder portion 25, and a spring material 39 is provided on the stepped portion 38. The role of the spring material 39 will be described later.
[0019] As shown in Figures 1 and 2, the belt holding portion 26 is provided on the front side of the holder portion 25 and has a roughly U-shape. Small holes 40 are formed at both ends of the belt holding portion 26, and the crimping material 41 is crimped into the small holes 40 to fix the belt holding portion 26 to the holder portion 25 (see Figure 2). The belt holding portion 26 serves to hold the tip portion 23b of the clothing belt 23, which is inserted through the frame portion 22.
[0020] The holder cover 28 shown in Figure 2 is provided to the storage section 24 so as to be able to be opened and closed, by inserting a shaft pipe (not shown) through the through hole 48 and the small hole 49 of the holder section 25. When closed, the claw portion 27 bites into the rear end portion 23a of the inserted garment belt 23, maintaining the fixed state of the garment belt 23 (see Figure 1). When the holder lid 28 is opened, the condition in which the claw portion 27 is embedded in the rear end portion 23a is released, making it possible to pull the belt 23 out of the storage portion 24.
[0021] As shown in Figure 2, the tilt switch section 31 is formed in a U-shape, with small holes 42 formed at both ends. The tilt switch unit 31 is located on the inside 29a of the connecting arm 29 shown in Figure 2, and is supported by inserting the pipe shaft 30 through the small holes 50 and 42 of the connecting arm 29, allowing it to move to a tilted position as shown by arrow C in Figures 4 and 5.
[0022] As shown in Figures 1 to 3, the stopper member 32 is provided in a state where it is sandwiched between the ends on both sides of the tilt switch section 31, and the pipe shaft 30 is inserted through the through hole 43, and the stopper member 32 rotates via the pipe shaft 30 in conjunction with the tilt movement of the tilt switch section 31.
[0023] As shown in Figure 2, the engaging projection 33 is integrally provided on the central part of the stopper member 32, protruding toward the rear end. Furthermore, as mentioned above, a spring material 39 is provided on the stepped portion 38, and the spring material 39 presses the engaging projection 33 from below. In other words, the engaging projection 33 normally protrudes above the stepped portion 38. Therefore, under normal circumstances, the pressing force of the spring material 39 causes the engaging projection 33 to protrude above the stepped portion 38, and as a result, it engages with the engaging claw 44 formed on the back surface of the belt 23, preventing the clothing belt 23 from being pulled out. On the other hand, when the tilt switch section 31 is tilted, the engaging projection 33 retracts into the stepped section 38, releasing the engagement with the engaging claw 44, which allows the belt 23 to be inserted and removed.
[0024] As shown in Figures 1, 2, 4, and 5, a vertical wall portion 45 is formed at the connection point between the frame portion 22 and the connecting arm 29, and the inclined switch portion 31 is provided along this wall portion 45. Therefore, the tilt switch unit 31 can only be tilted and moved in the opposite direction from the wall unit 45, and the operation of the tilt switch unit 31 is performed accurately and simply.
[0025] As shown in Figures 1, 2, 4, and 5, the upper edge of the connecting arm 29 has a curved portion 46, and the tilt switch portion 31 is configured to tilt and move along this curved portion 46 (see Figures 4 and 5). Therefore, the tilting movement of the tilt switch unit 31 is smooth, and its operation is stable.
[0026] When the tilt switch section 31 is in an upright position, a gap 47 is formed between the lower end portion 31a of the tilt switch section 31 on the tilting direction side and the upper edge of the connecting arm 29, as shown in Figure 4. The presence of this gap 47 allows the tilt switch section 31 to move smoothly and without hindrance, resulting in stable operation.
[0027] With the buckle 21 configured as described above, when the tilt switch portion 31 is tilted, the engaging projection portion 33 retracts into the stepped portion 38, allowing the belt 23 to be inserted and removed. Furthermore, when the tilt switch section 31 is in an upright position as shown in Figure 1, the engaging projection 33 protrudes above the stepped section 38 and engages with the engaging claw 44 formed on the back surface of the belt 23, preventing the belt 23 from being pulled out. In other words, since the tilt switch unit 31 is simply tilted using just one finger, the belt 23 can be pulled out with an extremely easy and simple operation compared to the buckle in conventional examples.
