Description

[Technical Field]

[0001] The present invention relates to a buckle for a clothing belt. [Background technology]

[0002] A known type of buckle known as a conventional pin buckle is one with the configuration shown in Figure 11 (A), (B), and (C). Figures 11 (A), (B), and (C) are all perspective views showing the back side of buckle 1, and show the procedure for opening size adjustment fitting 3 to release the engagement between buckle 1 and belt 2 when adjusting the length of belt 2.

[0003] This buckle 1 is roughly composed of a frame 4 consisting of a rectangular frame body, a pin 5 rotatably provided on the base 4a side of the frame 4, a connecting part 6 provided on the base 4a side of the frame 4, a size adjustment fitting 3 to which one end 2a side of the belt 2 is fixedly engaged, and a belt guide 7 provided near the size adjustment fitting 3.

[0004] Next, a procedure for opening the size adjustment fitting 3 to release the engagement between the buckle 1 and the belt 2 when adjusting the length of the belt 2 will be described. First, as shown in Figure 11(A), insert the tip of a flat-head screwdriver 8 or similar into the gap 3a of the size-adjustable metal fitting 3, and rotate it to lift the size-adjustable metal fitting 3 as shown in Figure 11(B). Once the size-adjustable metal fitting 3 opens, pull the belt 2 away from the jagged tab 3b that is biting into the belt 2 as shown in Figure 11(C). Thereafter, one end 2a of the belt 2, which has been cut to fit the wearer's waist circumference, is inserted into the size adjustment fitting 3 and closed to lock it in place, completing the process of adjusting the length of the belt 2.

[0005] Incidentally, Utility Model Registration No. 3217261 and Utility Model Registration No. 3208350 disclose pin buckles for clothing belts (see Patent Document 1 and Patent Document 2). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Utility Model Registration No. 3217261 [Patent Document 2] Utility Model Registration No. 3208350 Summary of the Invention [Problem to be solved by the invention]

[0007] With this conventional buckle 1, when adjusting the length of the belt 2, it is necessary to prepare a flat-head screwdriver 8, insert the tip of the screwdriver into the gap 3a of the size adjustment metal fitting 3, rotate it, lift it up, and open the size adjustment metal fitting 3, which is a complicated and troublesome process. Furthermore, there are various problems such as the risk of injury if the tip of the flathead screwdriver 8 pricks a finger, or the risk of damaging the leather of the belt 2.

[0008] Furthermore, in the conventional buckle 1, the pin 5 inserted into the pin hole (not shown) of the belt 2 and the size adjustment metal fitting 3 that fastens one end 2a of the belt 2 are separate entities, and the belt 1 is held in place by the pin 5 or the size adjustment metal fitting 3, respectively. Therefore, the tensile force when the belt 2 is worn is dispersed to two locations, the pin 5 and the size adjustment metal fitting 3, resulting in a problem in that the tensile strength of the belt 2 when worn is low.

[0009] Therefore, the conventional buckle 1 has the problem of making it easy to open the size adjustment fittings 3 when adjusting the length of the belt 2, and improving the tensile strength of the belt 2 when worn. [Means for solving the problem]

[0010] The gist of the present invention, which solves the problems of the above-mentioned conventional examples, is a buckle for a clothing belt, which is composed of at least a frame portion consisting of a rectangular frame body, a holder portion integrally formed on the base side of the frame portion and having a storage portion on the back side into which one end of the clothing belt is inserted, a roughly U-shaped belt guide provided on the front side of the holder portion, a size-adjusting holder lid that is freely openable and closable relative to the storage portion and has a claw portion that bites into the inserted one end of the clothing belt when closed, thereby maintaining a fixed state of the clothing belt, and a pin of the required length that is freely rotatable on the end of the holder lid and has a tip that fits into a groove on the front side of the frame portion.

[0011] The holder lid is opened with the pin raised and pressed down, and the state in which the claw portion is bitten into one end of the clothing belt is released; The pin to be inserted into the pin hole of the clothing belt and the holder cover into which the tab portion bites to maintain the fastened state of the clothing belt are integrally formed via a connecting portion; The tip end side of the pin is curved to form a curved portion along the groove portion of the frame portion; The frame portion, the holder portion, the belt guide, the holder cover, and the pin are made of zinc die-cast or metal; It includes: [Effects of the Invention]

[0012] With the buckle of this invention, by opening the holder lid while raising the pin and pushing it down, the state of the claw part biting into one end of the clothing belt is released, so the belt length can be easily adjusted with one touch. Furthermore, not only is there no need to prepare a flat-head screwdriver, or insert the tip of the screwdriver into the gap in the size adjustment metal fittings and rotate it to lift them up, as explained in the conventional example, but there are also various other excellent effects, such as no risk of pricking your finger with the tip of the flat-head screwdriver and injuring it, or of damaging the leather of the belt.

[0013] The holder cover is opened with the pin raised and pushed down, and the state of the claw part biting into one end of the clothing belt is released, so that the work of adjusting the length of the belt can be easily done with one touch. This eliminates the need to use a flat-head screwdriver, insert the tip of the screwdriver into the gap in the size adjustment metal fitting, and then rotate and lift it up, as explained in the conventional example. It also offers various excellent benefits, such as eliminating the risk of pricking your finger with the tip of the flat-head screwdriver or damaging the leather of the belt.

[0014] The pin that is inserted into the pin hole of the clothing belt and the holder cover, into which the claw part bites to keep the clothing belt fixed, are formed integrally via a connecting part, so that the pulling force when the belt is worn is not dispersed to two places as described in the conventional example. In other words, since the pin and the holder cover are integrally formed, the entire buckle is connected to the belt, which has the excellent effect of improving the tensile strength of the belt when worn.

[0015] The tip end of the pin is curved to fit along the groove of the frame, which has the excellent effect of allowing the tip end of the pin inserted into the pin hole when the clothing belt is worn to fit along the groove in a stable state without shifting or rattling.

[0016] The frame portion, holder portion, belt guide, holder lid, and pin are made of zinc die-cast or metal, which increases the strength of the buckle and provides excellent toughness, impact resistance, and durability. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0018] 1 to 5, the reference numeral 11 denotes a buckle for a clothing belt, and the buckle 11 includes a frame 12 having a rectangular frame body, a holder 15 integrally provided on a base 12c side of the frame 12, a belt guide 16 having a generally U-shape provided on the front side of the holder 15, and a holder cover 18 provided in an openable and closable manner relative to a storage section 14 (see FIGS. 5 and 8) of the holder 15. The holder lid 18 is configured with a pin 20 that is rotatably provided at the end of the holder lid 18. 1, 2, 4 and 5 all show a state in which one end 13a of the belt 13 is inserted into the storage section 14 of the holder section 15 and stored therein.

[0019] The frame 12, holder 15, belt guide 16, holder cover 18, and pin 20 are all made of zinc die-cast or metal, so the buckle 11 has high strength and is excellent in toughness, impact resistance, and durability.

[0020] The frame portion 12 consists of side portions 12a provided on both sides, a long plate portion 12b provided spanning the tip of the side portions 12a, and a base portion 12c formed at the rear end of the side portions 12a, and presents a rectangular frame body. A groove 12d is formed in the center of the front side of the long plate portion 12b of the frame portion 12. The tip portion 20a of the pin 20 is positioned along this groove 12d.

[0021] The holder portion 15 is provided integrally with the base portion 12c side of the frame portion 12, and a storage portion 14 is formed on the rear side of the holder portion 15, as shown in FIG.

[0022] The storage section 14 is structured so that one end 13a of the clothing belt 13 can be inserted into an entrance 14a shown in FIG. 8 to store it therein. As shown in FIG. 8, both side walls 14b of the storage section 14 are each formed with a long hole 14c.

[0023] The belt guide 16 is provided in a generally U-shape on the front side of the holder portion 15. Small holes 16b are formed in both end portions 16a of the belt guide 16, as shown in FIGS. Both ends 16a of the belt guide 16 are positioned along the long grooves 15a (see Figures 6 to 8) on both sides of the holder part 15, and are attached by pressing crimping material 21 into both ends of a pipe (not shown) that is inserted along the small hole 16b and the long hole 14c (see Figures 1 to 3). As shown in FIG. 10, the belt guide 16 is a portion through which the other end 13b of the belt 13 is inserted and held.

[0024] The holder lid 18 is provided on the rear side of the holder section 15 as shown in FIGS. 6 to 8, and is provided so as to be able to be opened and closed relative to the storage section 14 as shown in FIG. That is, as shown in Figures 6 to 8, a crimping material 21 is press-fitted into both ends of a pipe (not shown) that passes through a long hole 18c penetrating the side of the holder lid 18, a long hole 14c formed in the side wall 14b of the storage section 14, and a small hole 16b of the belt guide 16 (see Figures 1 to 3). As shown in FIG. 6, the holder lid 18 is formed with a plurality of protruding claws 18a.

[0025] When the holder lid 18 is closed, the claws 18a bite into one end 13a of the clothes belt 13 inserted into the storage compartment 14, maintaining the fixed state of the clothes belt 13 (see FIG. 5). In other words, the holder lid 18 is used when adjusting the size of the clothes belt 13, and is a so-called size adjustment tool.

[0026] 1 to 5, the pin 20 is rotatably provided at the end of the holder lid 18. That is, as shown in FIGS. 6 and 8, a C-shaped connecting portion 22 provided at the rear end of the pin 20 rotatably engages with an engaging portion 18b of the holder lid 18 (see FIGS. 6 and 8). In Figures 6 and 8, the pin 20 and the holder lid 18 are depicted as being separated vertically via the holder portion 15, but in reality, the pin 20 and the holder lid 18 are integrally formed via the connecting portion 22.

[0027] In this way, the pin 20 to be inserted into the pin hole (not shown) of the clothing belt 13 and the holder cover 18 into which the tab portion 18a bites to keep the clothing belt 13 in a fixed state are integrally formed via the connecting portion 22, so that the pulling force when the belt 13 is worn is not dispersed to two places as described in the conventional example (see arrows A and B in Figure 9). In other words, since the pin 20 and the holder lid 18 are formed integrally, the entire buckle 11 is connected to the belt 13 (see arrow C in Figure 10), which results in improved tensile strength of the belt 13 when worn.

[0028] The improvement in the tensile strength of the belt 13 when worn as described above will be explained based on experimental examples. FIG. 9 is a side view illustrating the tension state of the buckle 1 according to the conventional example, and the test result for measuring the tension state in this case is 343 Newtons (approximately 35 kg). FIG. 10 is a side view illustrating the tension state of the buckle 11 according to the present invention, and the test result for measuring the tension state in this case is 515 Newtons (approximately 52.5 kg). Thus, it was proven that the buckle 11 according to the present invention has strength approximately 1.5 times that of the buckle 1 according to the conventional example. The pass standard for clothing is 200 Newtons, and for belts it is 300 Newtons. *JIS L 1096A legal standard

[0029] The tip end 20a of the pin 20 is curved to fit along the groove 12d of the frame 12, forming a curved portion 20b. By forming the curved portion 20b in this manner on the pin 20, as shown in Figure 10, when the clothing belt 13 is worn, the tip portion 20a of the pin 20 inserted into the pin hole (not shown) can stably fit along the groove portion 12d without shifting or rattling.

[0030] As shown in FIG. 5, the buckle 11 configured as described above can be adjusted extremely easily by raising the pin 20 (see arrow D) and pushing it down (see arrow E) to open the holder lid 18 (see arrow F), thereby releasing the bite of the claw portion 18a into one end 13a of the clothing belt 13, making it possible to adjust the length of the belt 13 with a single touch.

[0031] Furthermore, not only is there no need to prepare a flat-head screwdriver 8, or to insert the tip of the screwdriver into the gap 3a of the size adjustment fitting 3 and rotate it to lift it up, as explained in the conventional example, but there is also no risk of injuring one's fingers with the tip of the flat-head screwdriver 8 or damaging the leather of the belt.
