Description

  The present invention relates to a buckle, for example, a buckle used for attaching a shoulder belt or handle of a bag, container, musical instrument, portable device, or the like.

  An example of a buckle used for attaching a shoulder belt to a portable video camera is disclosed in Japanese Utility Model Laid-Open No. 03-125407. The buckle has a first member having a hole in which a large diameter portion and a small diameter portion are continuous, a small diameter shaft portion that can move between the large diameter portion and the small diameter portion, and a large diameter portion that can pass through the small diameter portion but cannot pass through the small diameter portion. A second member having a large-diameter head, and a stopper for locking the second member in a state where the small-diameter shaft portion is located in the small-diameter portion of the hole of the first member. However, in this buckle, since the stopper in the locked state is exposed to the outside of the hole, a force acts on the stopper and the locking is easily released. In addition, the stopper is locked by the urging of a separate spring, and it is necessary to separately release the urging of the spring when releasing the locking of the stopper. Therefore, the stopper unlocking operation is troublesome. .

Japanese Utility Model Publication No. 03-125407

  Accordingly, an object of the present invention is to provide a buckle that is difficult to release by the stopper and that can be easily unlocked by the stopper.

  In order to solve the above problems, according to the present invention, a first member having a hole in which a large diameter portion and a small diameter portion are continuous, a small diameter shaft portion movable between the large diameter portion and the small diameter portion, and a small diameter shaft A second member having a large-diameter head that can pass through the large-diameter portion but cannot pass through the small-diameter portion, and a second member in which the small-diameter shaft portion is located in the small-diameter portion of the hole of the first member And a stopper including a fitting portion that can be fitted to the large-diameter portion.

In the buckle according to the present invention, after passing the large-diameter head of the second member through the large-diameter portion of the hole of the first member and then moving the second member to the small-diameter portion of the hole, the fitting portion of the stopper has a large-diameter By fitting into the portion, the second member in a state where the small diameter shaft portion is positioned at the small diameter portion of the hole of the first member can be locked.
The fitting part of the stopper fits into the large diameter part of the hole, so it is difficult to release the lock. On the other hand, the lock can be easily released by pulling the fitting part directly from the large diameter part with a finger. it can. Examples of the material of the first member and the second member include metals such as chromium steel, nickel steel, stainless steel, copper, aluminum, nickel, and alloys thereof, thermoplastic resins such as general-purpose plastics and engineer plastics. . Further, as will be described later, the fitting portion or the stopper may be formed of a material that is more flexible than the first member, but is not limited thereto, and both the first member and the fitting portion or the stopper are made of metal, synthetic resin, or the like. Can be formed.

  In one embodiment of the present invention, the fitting portion is made of a material that is more flexible than the first member. In this case, the fitting portion can be fitted and released from the large diameter portion of the hole while being elastically deformed as necessary. Preferred examples of the material for the fitting portion include thermosetting resin elastomers such as silicone rubber, fluororubber, and urethane rubber, and vulcanized rubber, but are not limited thereto.

  In one embodiment of the present invention, the entire stopper is made of the flexible material. In this case, the entire stopper can be elastically deformed when the fitting portion is fitted to and released from the large diameter portion of the hole.

  In one embodiment of the present invention, the stopper is connected to the first member. In one example of this embodiment, the stopper includes a stopper base end portion accommodated in the first member, a hinge portion extending from the stopper base end portion, and a base portion provided at the tip of the hinge portion, and the fitting The joint part protrudes from the base part. In this example, when the stopper base end is accommodated in the first member, the stopper and the first member are connected, and the fitting portion of the stopper is rotated from the hinge portion with respect to the first member, so that the hole is formed. Fits into the large diameter part.

  In another embodiment of the present invention, the stopper is separated from the first member. In one example of this embodiment, the stopper includes a base portion and a connecting leg portion extending from the base portion, and the first member has a hole through which the connecting leg portion is passed. In this example, the stopper and the first member in the separated state are connected by passing the connecting leg portion of the stopper through the hole of the first member.

  In one embodiment of the present invention, the fitting portion is in contact with the small diameter shaft portion in a state of being fitted to the large diameter portion when the small diameter shaft portion of the second member is located at the small diameter portion. In this case, rattling of the second member is prevented.

  In one embodiment of the present invention, the stopper has a ring portion that fits into the large-diameter head of the second member in a state where the small-diameter shaft portion is positioned in the small-diameter portion of the hole of the first member. By fitting the ring portion to the large-diameter head of the second member in a state where the stopper is locked, the force for restraining the second member to the small-diameter portion is increased, and the stopper is difficult to come off from the locking position.

  In one embodiment of the present invention, the fitting portion of the stopper has a convex portion that protrudes in the fitting direction from the hole in a state fitted to the large diameter portion of the hole of the first member. This convex part can play the role which prevents the movement from the small diameter part of a 2nd member to a large diameter part by contacting a 2nd member in the state which the stopper has not fitted in the hole of the 1st member. In this embodiment, the convex portion may have a tapered surface that reduces the degree of protrusion in a direction away from the second member when the fitting portion is fitted to the large diameter portion. By providing such a tapered surface, even if the stopper is inclined with respect to the second member, the convex portion of the fitting portion does not come into surface contact with the base material to which the second member is fixed. It becomes difficult to receive a force in the direction of disengagement.

  In the buckle according to the present invention, the second member in a state where the small-diameter shaft portion is positioned at the small-diameter portion of the hole is locked by fitting the fitting portion of the stopper into the large-diameter portion of the hole of the first member. Therefore, the engaging portion of the stopper in the locked state is hardly exposed outside the hole, and the locking is difficult to be released even if a force acts on the stopper. Further, the engagement can be easily released by pulling out the fitting portion from the large diameter portion with a finger.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to such embodiments, and may be appropriately changed within the scope of the utility model registration request. . FIG. 1 is a perspective view of a buckle 1 according to a first embodiment of the present invention. The buckle 1 includes a first member 10 having a hole 30 and a second member 40 that is detachably coupled to the first member 10 through the hole 30. As an example, the buckle is used for attaching a grip for a user to hold by hand or hook on a hook, but the present invention is not limited to this. FIG. 2 is a cross-sectional view of the first member 10 taken along line AA of FIG. The first member 10 is fixed to one end portion (or both end portions) 51 of the strap 50 serving as the grip, and one or two second members 40 are fixed to the base body 60 which is a part of the school bag.

  The first member 10 includes a first member main body (hereinafter also simply referred to as “main body”) 11 made of a zinc alloy in which the hole 30 is formed, and a fitting portion 21 for fitting into a part of the hole 30 of the main body 11. And a stopper 20 having the same. In this embodiment, the stopper 20 is connected to the main body 11, but the stopper 20 may be separated from the main body 11. The stopper 20 as a whole including the fitting portion 21 is made of silicone rubber and has flexibility, that is, flexibility. The main body 11 includes a strap receiving portion 12 that receives the end portion 51 of the strap 50 from the opening portion 12c, and an arrow B side in FIG. 2 from the strap receiving portion 12 (hereinafter, the arrow B side is referred to as a “base end side” with respect to the first member 10). 2 and is fixed to the strap 50 by the rivet 52 (upper and lower are based on the paper surface of FIG. 2), and the fixed portion 13 in FIG. 2 on the opposite side of the base end side from the strap receiving portion 12 A rectangular box-shaped stopper base end receiving portion 14 that extends to the arrow C side (hereinafter, arrow C side is referred to as a “tip side” with respect to the first member 10) and stores a stopper base end portion 22 of the stopper 20 to be described later; And a connecting portion 15 having a hole 30 extending from the stopper base end accommodating portion 14 to the distal end side.

  As shown in FIG. 2, the main body 11 also includes an upper plate portion 11 a, a lower plate portion 11 b, and a side plate portion 11 c that connects and closes the distal end sides between the upper and lower plate portions 11 a and 11 b. The upper and lower plate portions 11a and 11b form a fixed portion 13 and upper and lower portions of the strap receiving portion 12 and the stopper base end accommodating portion 14, respectively. The lower plate portion 11b also gradually rises downward from the proximal end side to the distal end side at the lower part of the stopper proximal end accommodating portion 14, and then increases in thickness, and then extends to the distal end side with a constant thickness. Make. The side plate portion 11c is provided on the left and right sides of the strap receiving portion 12 (left and right are along the width direction of the strap 50 in FIG. 1), and the left and right side portions of the stopper base end accommodating portion 14. 14a and 14a and the front end side part 14b. The main body 11 is symmetrical. The length between the left and right side portions 12a, 12a of the strap receiving portion 12, that is, the lateral width is slightly larger than the lateral width (length in the width direction) of the strap 50. The fixed portion 13 becomes constant after the lateral width is gradually reduced from the strap receiving portion 12 to the proximal end side, and becomes semicircular at the proximal end portion. The lateral width of the stopper base end accommodating portion 14 is smaller than the lateral width of the strap receiving portion 12, and the lateral width of the fixed portion 13 is slightly larger than a certain portion. The inside of the stopper base end accommodating portion 14 is continuous with the inside of the strap receiving portion 12. In this embodiment, the end portion 51 of the strap 50 inserted into the trap receiving portion 12 is in contact with the end surface on the distal end side of the stopper base end portion 22 in the stopper base end accommodating portion 14 (see FIG. 2). A hole 14c is formed in the distal end side portion 14b of the stopper base end accommodating portion 14 so as to allow a later-described hinge portion 23 of the stopper 20 to pass therethrough. The hole 30 of the connecting portion 15 has a large-diameter portion 31 on the proximal end side and a small-diameter portion 32 on the distal end side that partially overlaps the large-diameter portion 31 and continues. The connecting portion 15 includes a wide end portion 15a corresponding to the large diameter portion 31 and a narrow portion 15b extending from the wide portion 15a to the distal end side and surrounding the small diameter portion 32 in a semicircular shape.

  The stopper 20 includes a stopper base end portion 22 that is accommodated in the stopper base end portion receiving portion 14 of the main body 11, and the stopper base end portion receiving portion 14 from the center in the left-right direction of the end surface on the front end side of the stopper base end portion 22. A narrow plate-like hinge portion 23 extending to the front end side through the hole 14c, a substantially rectangular plate-like base portion 24 extending from the front end side end of the hinge portion 23 to the front end side while expanding in the left-right direction, and a base And a fitting portion 21 that protrudes downward from the lower surface of the portion 24 and can be fitted to the large-diameter portion 31 of the hole 30 of the connecting portion 15. The upper surface of the hinge portion 23 is slightly lower than the upper surface of the stopper base end portion 22 in the horizontal state in which the fitting portion 21 is fitted to the large diameter portion 31 (see FIG. 8). In the horizontal state, it is flush with the lower surface of the stopper base end 22. The thickness of the hinge part 23 is about 2/3 of the stopper base end part 22. The base portion 24 may be harder than other portions of the stopper. As an example of hardening the base portion, the entire base portion is formed of the same hard material as that of the first member. Or a base part is formed with a hard member and a soft member, and it arrange | positions so that a hard member may be covered with a soft member.

  FIG. 3 is a perspective view showing a state in which the fitting portion 21 of the stopper 20 is fitted into the large diameter portion 31 of the hole 30 of the main body 11. FIG. 4 is a cross-sectional view of the main body 11 and the stopper 20 along the line DD in FIG. When the user holds the base portion 24 and engages or releases the fitting portion 21 with respect to the large-diameter portion 31 of the hole 30, the hinge portion 23 moves up and down around the proximal end of the hinge portion 23. It is possible to turn while bending. The stopper 20 that is not held by the user attempts to elastically return from the non-fitted state in which the fitting portion 21 in FIG. 2 is outside the hole 30 to the horizontal state in FIG. The base portion 24 has substantially the same horizontal width and vertical width (length in the base end side-distal end direction) as the wide portion 15a of the connecting portion 15, and is recessed in an arc shape at the distal end end portion toward the base end side. It has a notch 24a. The fitting portion 21 has a shape that matches the large-diameter portion 31 of the hole 30 and is in a fitted state (a state in which the fitting portion 21 is fitted to the large-diameter portion 31). , The same), a vertical surface 21a along the vertical direction and a tapered surface 21b adjacent to the lower side of the vertical surface 21a. The tapered surface 21b is inclined so as to gradually reduce the thickness of the fitting portion 21 toward the distal end side. In the lower part of the fitting part 21, there are a convex part 21c slightly protruding downward (fitting direction) from the hole 30 in the fitted state, and a concave part 21d recessed upward between the convex part 21c and the tapered surface 21b. It is formed. As can be seen from FIG. 8, the downward protrusion of the convex portion 21 c gradually increases from the proximal end to the distal end of the fitting portion 21, and immediately falls to the upper portion immediately after reaching the maximum. 21d. Therefore, the lower surface (the end surface on the side protruding in the fitting direction) of the convex portion 21 c becomes a tapered surface 21 e that reduces the degree of protrusion toward the base end side that is the direction away from the second member 40. The thickness at the base end side end of the fitting portion 21 and the thickness at the portion between the tapered surface 21 b and the concave portion 21 d coincide with the depth of the hole 30. Further, as can be seen from FIG. 4, the left and right side surfaces 21 f of the fitting portion 21 face the inner side surface 15 c that defines the large diameter portion 31 of the wide portion 15 a of the connecting portion 15 in the fitted state.

  FIG. 5 is a cross-sectional view of the second member 40 taken along the line aa in FIG. The second member 40 is made of a zinc alloy, and is a cylindrical small-diameter shaft portion 41 and a disk having a diameter larger than that of the small-diameter shaft portion 41 adjacent to the upper side of the small-diameter shaft portion 41 (upper and lower are based on the paper surface of FIG. A large-diameter head portion 42 and a disc-shaped base portion 43 adjacent to the lower side of the small-diameter shaft portion 41 and having a slightly larger diameter than the large-diameter head portion 42 are provided. The second member 40 is fixed to the base 60 of the school bag with a rivet 44 that is shown integrally with the second member 40 for convenience. The height of the small diameter shaft portion 41 slightly exceeds the thickness of the connecting portion 15 of the first member 10, that is, the depth of the hole 30, and the small diameter shaft portion 41 is the large diameter portion 31 of the hole 30 of the first member 10. And the small diameter portion 32 can be moved. The large-diameter head portion 42 can pass through the large-diameter portion 31 of the hole 30 of the first member 10 in the axial direction, but cannot pass through the small-diameter portion 32 in the axial direction.

  Next, the process of connecting the first member 10 and the second member 40 will be described. First, the large-diameter head portion 42 of the second member 40 is passed through the large-diameter portion 31 of the hole 30 of the first member 10. FIG. 6 is a top view showing a state where the large-diameter head portion 42 is passed through the large-diameter portion 31. At this time, the small diameter shaft portion 41 of the second member 40 is disposed in the large diameter portion 31. Next, the small diameter shaft portion 41 of the second member 40 is horizontally moved from the large diameter portion 31 to the small diameter portion 32, and then the stopper 20 is pushed toward the hole 30 of the main body 11. The direction in which the stopper 20 is pushed is the direction in which the stopper 20 returns elastically. At this time, as shown in FIG. 7, the end portion on the front end side of the fitting portion 21 of the stopper 20 abuts against the large-diameter head portion 42 of the second member 40, but the tapered surface 21 b of the fitting portion 21 has the large-diameter head portion. The large-diameter head portion 42 can be crossed while being elastically deformed so that the fitting portion 21 is slightly contracted toward the proximal end side in contact with 42. The elastic deformation of the fitting portion 21 at this time is promoted by the concave portion 21 d of the fitting portion 21. The fitting portion 21 is restored when it exceeds the large-diameter head portion 42 of the second member 40, and fits exactly into the large-diameter portion 31 of the hole 30 of the first member 10. 8 and 9 are a sectional view and a top view of the fitted state. When the fitting part 21 fits closely to the large diameter part 31, the second member 40 cannot move to the large diameter part 31 and is restrained by the small diameter part 32. Since the large-diameter head portion 42 cannot pass through the small-diameter portion 32, the second member 40 located in the small-diameter portion 32 cannot be detached from the hole 30 of the first member 10. In the fitted state, a part of the large-diameter head portion 42 of the second member 40 enters the notch 24 a of the base portion 24 of the stopper 20, and the portion of the large-diameter head portion 42 is the tip side end portion of the fitting portion 21. The upper surface of the fitting member 21 is pressed down to prevent the fitting portion 21 from coming off. The flexibility of the stopper 20 is such that even when the second member 40 is about to move toward the large diameter portion 31 in the fitted state, the fitting portion 21 and the base portion 24 withstand the pressure from the second member 40 and are easily elastic. It is set not to deform. Further, as can be seen from FIG. 8, since the thickness of each of the main body 11 and the stopper 20 is smaller than the protruding height of the second member 40 from the base body 60, the product height (thickness) of the entire buckle is small. Furthermore, in this embodiment, the vertical surface 21a of the fitting part 21 is in contact with the small-diameter shaft part 41 of the second member 40 in the fitted state (see FIG. 8). Since the vertical surface 21a is sandwiched between the narrow portion 15b of the connecting portion 15 and the distal end side of the inner side surface 15d that defines the small diameter portion 32, rattling of the second member 40 can be prevented. Preferably, the vertical surface 21a of the fitting portion 21 in contact with the small-diameter shaft portion 41 presses the small-diameter shaft portion 41 toward the distal end side of the connecting portion 15, and thereby the small-diameter shaft portion 41 is formed on the narrow portion 15b. It is pressed toward the tip side of the inner side surface 15d. Note that the vertical surface 21 a of the fitting portion 21, that is, the end surface on the front end side may be slightly separated from the small diameter shaft portion 41 of the second member 40 in the fitted state.

  FIG. 10 is a cross-sectional view showing a state where the stopper 20 in a non-fitted state is in contact with the second member 40. In this state, for example, after the user passes the second member 40 through the large diameter portion 31 of the hole 30 of the first member 10 and moves to the small diameter portion 32, the stopper 20 is fitted into the large diameter portion 31 of the hole 30. It is in a state where it has been forgotten. In such a case, since the second member 40 is not locked to the small diameter portion 32, the second member 40 tends to move to the large diameter portion 31. At this time, the stopper 20 in the non-fitted state is subjected to a force to move downward to elastically return to the horizontal state fitted with the large-diameter portion 31, and this force tries to move to the large-diameter portion 31. The two members 40 act to push back toward the small diameter portion 32 side. Therefore, even if the stopper 20 is forgotten to be locked, the first member 10 and the second member 40 are not easily separated. In FIG. 10, the large-diameter head portion 42 of the second member 40 that is about to move to the large-diameter portion 31 is in contact with the distal end side end of the convex portion 21 c of the fitting portion 21. It plays a role of preventing displacement to the large diameter portion 31 side.

  FIG. 11 is a cross-sectional view showing a state where the first member 10 including the stopper 20 in the fitted state is inclined with respect to the second member 40 (inclined state). In this inclined state, the first member 10 is inclined with respect to the second member 40 so that the distal end side is displaced upward and the proximal end side is displaced downward compared to the horizontal state of FIG. In this case, since the lower surface of the convex portion 21c of the fitting portion 21 is a tapered surface 21e, the tapered surface 21e of the convex portion 21c is in surface contact with the base member 60 to which the second member 40 is fixed in an inclined state. Without contact, only the tip side end of the convex portion 21c contacts. Therefore, the fitting part 21 does not receive much force that is pushed upward from the base material 60, so that the fitting part 21 is detached from the large-diameter part 31 and the locking of the second member 40 by the stopper 20 is released. There is nothing wrong. Even if the fitting portion 21 receives some force that is pushed upward from the base material 60, the large-diameter head portion 42 of the second member 40 restrains the fitting portion 21 via the notch portion 24 a of the base portion 24. Therefore, the stopper 20 cannot be easily locked.

  FIG. 12 is a perspective view showing a modified example of the first member and the stopper of the buckle according to the present invention. In this example, the first member 110 and the stopper 120 are separated. The hole 130 of the first member 110 is substantially the same as the hole 30 of the first member 10 described above, and has a large diameter portion 131 and a small diameter portion 132. The first member 110 is made of a zinc alloy, and includes a strap receiving portion 112 that receives an end portion of the strap 50, a fixed portion 113 that extends from the strap receiving portion 112 to the proximal end side and is fastened to the strap 50 by a rivet 52, and a strap And a connecting portion 115 having a hole 130 extending from the receiving portion 112 toward the distal end side. The connecting portion 115 has a substantially rectangular wide portion 115a on the base end side corresponding to the large diameter portion 131 of the hole 130, a narrow portion 115b extending from the wide portion 115a to the distal end side, and surrounding the small diameter portion 132 in a semi-annular manner. including. The lateral width of the wide portion 115 a is the same as that of the strap receiving portion 112. In the vicinity of the left and right ends of the wide portion 115a, a rectangular hole 115c for allowing a later-described connecting leg portion 125 of the stopper 120 to pass is provided.

  The stopper 120 is made of silicone rubber, and has a rectangular plate-like base portion 124 and a fitting portion that protrudes downward from the lower surface of the base portion 124 and can be fitted to the large-diameter portion 131 of the hole 130 of the connecting portion 115. 121, and a connecting leg 125 extending in an L-shape from the left and right end portions of the base portion 124 downward to the fitting portion 121 side. The connecting leg portion 125 has a base portion 125a extending downward from the base portion 124 and a lower end portion 125b extending from the lower end of the base portion 125a toward the fitting portion 121 side. The fitting part 121 can have a convex part similar to the convex part 21c of the fitting part 21 of the stopper 20 in the first embodiment. In this embodiment, after the second member 40 is received in the large diameter portion 131 of the hole 130 of the first member 110 and then transferred to the small diameter portion 132, the connecting leg portion 125 of the stopper 120 is moved to the lower end portion 125b and then to the base portion 125a. The stopper 120 is attached to the connecting part 115 through elastic deformation in the hole 115c of the connecting part 115 in this order, and the fitting part 121 is fitted into the large diameter part 131. As a result, the second member 40 is locked to the small diameter portion 132. The fitting portion 121 fitted into the large diameter portion 131 is preferably in contact with the small diameter shaft portion 41 of the second member 40. FIG. 13 is a cross-sectional view of the connecting portion 115 and the stopper 120 in the fitted state. After the connecting leg portion 125 is passed through the hole 115c of the connecting portion 115, the base portion 124 faces the upper surface of the connecting portion 115, and the lower end portion 125b of the connecting leg portion 125 faces the lower surface of the connecting portion 115. Is done. Accordingly, the base portion 124 and the lower end portion 125b sandwich the connecting portion 115, and the stopper 120 and the connecting portion 115 of the first member 110 are firmly connected. As can be seen from FIG. 13, the thickness of the stopper 120 is substantially the same as the thickness of the strap receiving portion 112.

  FIG. 14 is a perspective view showing another modified example of the first member and the stopper of the buckle according to the present invention. In this example, the first member 210 and the stopper 220 are separated. The hole 230 of the first member 210 is substantially the same as the hole 30 of the first member 10 described above, and has a large diameter portion 231 and a small diameter portion 232.
