Description

Technical Field

[0001] The present invention relates to a buckle, and more particularly, to a buckle comprising a plug component and a socket component installed at the end of a belt or strap attached to a variety of articles such as clothing, bags, backpacks, helmets, etc., the components are combined in a disassembly manner, and can be used by simple operation while maintaining a firm and stable combined state. Background Art

[0002] As a fastener for combining and fixing two parts, the buckle realizes elastic combination by integrally molding a plastic material, and is widely used due to its light weight and easy fastening.

[0003] The commonly used buckle is composed of a plug component and a socket component. A cavity is formed in the socket component, and a locking arm elastically combined with the cavity is formed in the plug component, so that the plug component and the socket component are combined.

[0004] However, this conventional buckle has a pair of locking arms with a complex structure, a cavity for receiving and combining a socket component of the pair of locking arms, and a complex internal combination structure, thus requiring considerable technical effort in manufacturing.

[0005] Furthermore, the existing buckle is connected by holding the plug part and the socket part with both hands and inserting them into each other, and when separating, the plug part and the socket part are also held with both hands and separated by pressing the locking arm of the plug part. As mentioned above, when connecting, the existing ordinary buckle can only be connected by accurately combining both hands.

[0006] When operating a belt or strap provided in a backpack or the like carried during activities such as mountaineering or hiking, it is necessary to stop all other actions and use both hands to engage the buckle, which causes the inconvenience of having to put down other items in the hands. Therefore, a buckle that can be more easily engaged is needed.

[0007] In recent years, in order to solve the above-mentioned problems, a magnetic buckle that can be easily fastened has been proposed.

[0008] In order to solve the above problems, the applicant invented Korean Patent Document 1 and Korean Patent Document 2, which are technologies as follows: magnets are provided without a locking arm structure for mutual coupling, so that they can be coupled by strong magnetic induction just by being close to each other, thereby providing the convenience of simple coupling.

[0009] However, although Korean Patent Document 1 and Korean Patent Document 2 provide the convenience of easy combination, they are difficult to separate with one hand or have a complex structure, resulting in poor productivity.

[0010] Furthermore, when external pressure is applied in a specific direction, the plug component and the socket component are easily separated, which may lead to accidental separation and thus pose a potential safety hazard.

[0011] Therefore, there is a need for a buckle that provides the convenience of easy assembly and disassembly while being able to stably maintain a coupled state.

[0047] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings.

[0048] Figure 1 Parts (a) and (b) of FIG. 1 are three-dimensional views showing the combination and separation of the buckle according to an embodiment of the present invention. Figure 2 To show the strap connected to Figure 1 A perspective view of an example of the state of the buckle, Figure 3 Parts (a) and (b) of Figure 1 The back stereogram of Figure 4 This is an exploded perspective view of the buckle. Figure 5 for Figure 4 The back stereogram of Figure 6 Parts (a) and (b) are the main view and AA line cross-sectional view of the separated buckle. Figure 7 Parts (a) and (b) are the front view and BB line cross-sectional view of the combined buckle.

[0049] Reference Figures 1 to 7 The buckle of one embodiment of the present invention includes a plug component 100, a socket component 200 and a locking component 300. The plug component 100 is combined with the socket component 200 and maintained in combination by the locking component 300.

[0050] These are usually molded from synthetic resin, applied to backpacks or bags, etc., and used by connecting with a strap S.

[0051] A cross bar 102 and a strap hook rod 103 connected by hooking the free end of the strap S are formed in a spanning manner behind the base 101 of the main body of the plug component 100. The length of the strap S can be adjusted by alternately winding the strap S around the cross bar 102 and the strap hook rod 103.

[0052] The support arms 110 are formed to extend at both ends in the front direction of the base 101. The support portion 120 is formed between the two support arms 110 along the front of the base, and the locking member 300 is provided in the support portion 120.

[0053] The support portion 120 is in a state of protruding forward from the base, and thus a hinge groove 121 is formed between each support arm 110 and the support portion 120 , and hinges 122 for setting the locking component 300 are protrudingly formed on both side surfaces of the support portion 120 .

[0054] A clamping protrusion 105 is formed on the back side of the base 101 at a distance from the support portion 120 to clamp the central front end of the socket member 200 when the socket member 200 is coupled, so that the coupling state with the socket member 200 becomes firm.

[0055] The socket component 200 and the plug component 100 face each other and are combined, and support cavities 210 for inserting the support arms 110 are formed at both ends, and a central cavity 220 with an open front surface is formed between the two support cavities 210 .

[0056] The supporting cavity 210 and the central cavity 220 are separated by a partition 211 .

[0057] The support arm 110 of the plug component 100 is introduced into and accommodated in the support cavity 210 when combined with the socket component 200. Preferably, the boundary portion in the combined state is designed to be closely finished to form a sense of unity as shown in the figure.

[0058] A horizontal bar 203 to which a strap S can be connected is also formed at the rear of the socket component 200. Like the plug component 100, a strap hook rod is also provided to adjust the strap.

[0059] The central cavity 220 of the socket component 200 is a space for accommodating the locking component 300 and placing and combining the locking component 300 , and the width of the central cavity 220 corresponds to the width of the locking component 300 .

[0060] An inclined guide portion 221 for guiding the locking member 300 to enter is formed in the middle of the bottom surface of the central cavity 220 .

[0061] An inclined protrusion 222 for guiding the locking member 300 to enter and engage is formed at the rear end of the bottom surface of the central cavity 220 .

[0062] Slots 223 for guiding the locking member 300 to fit closely are formed along the length direction on both sides of the central cavity 220, and a locking portion 225 is formed in the form of a shoulder at the rear end of the slot 223. The hook 331 of the locking member 300 is locked and combined with the locking portion 225, and preferably, the shoulder is processed into a curved surface for smooth separation.

[0063] A first magnet M1 is buried inside the central cavity 220 .

[0064] The locking component 300 is rotatably disposed on the supporting portion 120 of the plug component 100, and is received in the central cavity 220 of the jack component 200 when the plug component 100 is combined with the jack component 200. To this end, hinge holes 312 are respectively formed at the rear end of the locking component 300, and the hinge holes 312 are used to make the connecting portions 310 protrude at both sides and be respectively inserted into the hinges 122, and a recess 311 is formed between the connecting portions 310.

[0065] The two connection parts 310 of the locking component 300 are combined with the hinge 122 and are located on two sides of the support part 120 , and rotate around the hinge 122 .

[0066] That is, when the locking member 300 is disposed on the plug member 100 , the connecting portion 310 of the locking member 300 is introduced into the hinge groove 121 of the plug member 100 , and the supporting portion 120 is combined in the state of being introduced into the recess 311 of the locking member 300 .

[0067] By setting the contact relationship between the end of the connecting portion 310 and the base inside the hinge groove 121 and the contact relationship between the front end of the supporting portion 120 and the inner wall of the recess 311, the locking component 300 can be set to rotate only a specified angle instead of fully rotating.

[0068] As shown in the figure, the structure of the shoulder 315 formed at the end of the connecting portion 310 is also for controlling the rotation angle.

[0069] Therefore, unnecessary excessive rotation can be controlled to maintain the prescribed form and achieve the necessary rotation.

[0070] Moreover, an inclined surface 123 is formed on one side of the hinge 122 so that the hinge 122 of the support part 120 and the hinge hole 312 of the locking component 300 can be assembled smoothly, and an entry groove 313 for guiding the hinge 122 to enter can be formed on one side of the hinge hole 312.

[0071] The entry groove 313 may also be formed with an inclined guide surface.

[0072] Thus, the inclined surface 123 of the hinge 122 and the entry groove 313 of the connecting portion 310 guide the hinge 122 to enter smoothly, and finally achieve the combination by pressing.

[0073] The locking member 300 has a combination protrusion 320 formed on both sides thereof to fit with the narrow groove 223 of the central cavity 220, and a hook 331 formed at the front end thereof to be combined with the locking portion 225 of the jack member 200. Like the locking portion 225, preferably, the edge of the hook 331 is processed into a curved surface to enable smooth combination and separation.

[0074] In the accompanying drawings, the hook portion 331 is only formed on both sides of the end of the coupling plate 330 for finishing the front end of the locking component 300, but can be formed on the entire end of the coupling plate 330, and the corresponding locking portion 225 of the socket component 200 can also be formed to match it.

[0075] Therefore, due to the structure of the side plate forming the coupling protrusion 320 and the coupling plate 330 forming the hook 331 , the locking member 300 is in a box form and is coupled to surround the bottom surface of the central cavity 220 of the socket member 200 .

[0076] The front end of the locking member 300 further protrudes in front of the above-mentioned coupling plate 330, thereby forming a handle 340 for separating the buckle. Therefore, by lifting the operation of the handle 340, the plug member 100 and the socket member 200 are simply separated.

[0077] A cord connection hole 341 is formed in the handle 340. If a cord 342 is connected to the cord connection hole 341, the buckle can be separated by simply pulling the cord 342.

[0078] The locking member 300 is embedded with a second magnet M2 that corresponds to the first magnet M1 of the central cavity 220 when combined with the central cavity 220 of the socket member 200 .

[0079] Therefore, when the plug component 100 and the socket component 200 are close to each other, the plug component 100 and the socket component 200 are instantly combined by the magnetic force of the first magnet M1 of the socket component 200 and the second magnet M2 of the locking component 300 .

[0080] When the plug component 100, the socket component 200 and the locking component 300 are combined into one, the partition 211 for separating the central cavity 220 of the socket component 200 and the support cavity 210 is introduced into the hinge groove 121 of the plug component 100 and fits tightly between the support arm 110 and the connecting part 310, thereby forming a dense combination structure.

[0081] The buckle according to the above-mentioned structure functions as follows.

[0082] First, when the plug component 100 and the socket component 200 are brought close to combine them, the first magnet M1 and the second magnet M2 are strongly attracted to each other by magnetic force and are instantly combined with each other, thereby the plug component 100 and the socket component 200 are tightly attached and combined.

[0083] Figure 8 Parts (a) to (c) of FIG. 1 show the cross-sectional states of the plug component 100, the socket component 200 and the locking component 300 in combination. Fig. 9 Parts (a) to (c) are perspective views sequentially showing the coupled states of the buckle.

[0084] Figure 8 Part (a) and Fig. 9 (a) shows the plug component 100 and the socket component 200 approaching each other in a spaced-apart state. Figure 8 Part (b) and Fig. 9Part (b) shows that when the plug component 100 and the socket component 200 are further approached, the sides of the first magnet M1 and the second magnet M2 approach each other, and according to the mutually repelling magnetic characteristics, the front end of the locking component 300 instantly rotates to the upper side and bends.

[0085] When the locking component 300 moves forward further in this state, it enters the central cavity 220 of the jack component 200. At this moment, due to the magnetic force generated by the first magnet M1 and the second magnet M2 approaching each other, the locking component 300 instantly moves to the central cavity 220 of the jack component 200, and at the same time, it is closely attached and combined, as shown in FIG. Figure 8 Part (c) and Fig. 9 As shown in part (c) of .

[0086] The plug component 100 is pulled together with the locking component 300 and moves instantly, and as the locking component 300 is combined with the central cavity 220 of the socket component 200 , the support arm 110 of the plug component 100 is introduced and combined into the support cavity 210 of the socket component 200 .

[0087] In this combined state, the combining protrusion 320 of the locking component 300 is tightly attached to and combined with the narrow groove 223 of the socket component 200. As the front end combining plate 330 of the locking component 300 covers the rear of the central cavity 220, the hook 331 remains in a fastened state combined with the locking portion 225 of the socket component 200.

[0088] In the process that the locking component 300 is strongly introduced into the inner side of the central cavity 220 by the magnetic force of the magnet, the combining plate 330 contacts the bottom surface of the central cavity 220, and the combining plate 330 is naturally guided by the inclined guide portion 221 formed on the bottom surface of the central cavity 220, and is guided upward from the final position by the inclined protrusion 222 formed at the rear end of the central cavity 220.

[0089] Therefore, the locking member 300 that attempts to adhere by magnetic force is lifted upward by the inclined protrusion 222, and then rotates strongly downward and adheres to the central cavity 220 at the end of the guide section of the central cavity 220, and the hook 331 is instantly engaged with the locking portion 225. That is, the inclined protrusion 222 plays the following role: ensuring a sufficient rotation distance for the locking member 300 to adhere more strongly and engage, and generating a strong tightening sound due to the impact during the engagement.

[0090] This combination process is achieved instantly through strong magnetic force. When the buckle is connected, Figure 8 As shown in part (c) of FIG. 1 , the first magnet M1 and the second magnet M2 face each other in an overlapping manner.

[0091] Furthermore, in the coupled state, the clamping protrusion 105 of the plug member 100 clamps and supports the front end portion of the socket member 200, so that the coupled state can be further stabilized.

[0092] The buckles in this fastened state will not separate from each other due to external pressure from any direction.

[0093] In particular, as the locking component 300 is tightly attached to the central cavity 220 of the socket component 200, a stable combination state can be maintained through the combination of the hook portion 331 and the locking portion 225. In addition to the combination of the support arm 110 and the support cavity 210, the front end of the socket component 200 can also be stably clamped by the clamping protrusion 105 of the plug component 100, so that a more firmly fastened state can be maintained.

[0094] Fig.10 The action of separating the plug component 100 from the socket component 200 is shown in a cross-sectional view.

[0095] like Fig.10 As shown, when the buckle is separated, the separation is performed by lifting the front handle 340 of the locking member 300 by hand.

[0096] The locking component 300 is strongly attached to the central cavity 220 of the socket component 200 by magnetic force. When the locking component 300 is lifted by overcoming the magnetic force, the hook portion 331 rotates around the hinge 122 while separating from the locking portion 225, thereby releasing the locking component 300 from the socket component 200.

[0097] The contact portion between the hook portion 331 and the locking portion 225 is a curved surface, so the handle 340 can be lifted without difficulty.

[0098] When the plug member 100 is moved rearward relative to the socket member 200 in a state where the locking member 300 is rotated and lifted as described above, the buckle is separated.

[0099] However, since the action of lifting the front end handle 340 of the locking component 300 is performed together with the action of pushing rearward while rotating from the front end of the locking component 300 toward the hinge 122, the action of lifting the handle 340 includes the action of pushing the plug component 100 rearward, so that the actions are performed simultaneously without the need for a separate action of pushing the plug component rearward.

[0100] Therefore, the plug component 100 and the socket component 200 can be easily separated only by rotating the handle 340 of the locking component 300 .

[0101] Usually, the plug part or the socket part of the buckle is used in a state set on the belt, so the buckle can be separated by simply lifting the locking part with fingers without holding the socket part or the plug part, and finally the buckle can be easily separated with one hand.

[0102] Furthermore, when the cord 342 is connected to the cord connection hole 341 of the locking member 300 , the buckle can be separated simply by pulling the cord 342 .

[0103] As described above, during the connection process between the plug component and the socket component, instantaneous connection can be achieved based on magnets, so that the connection with a belt or a strap can be achieved with one hand, and the separation can also be easily achieved with one hand.

[0104] As described above, the assembly and disassembly operation can be easily performed, and the combined state can be firmly and stably maintained, so that it can be used safely.

[0105] In addition, the buckle of the present invention may be provided with a plurality of units on one side of the main body that can be connected to connecting parts such as hooks, loops, clips, fastening buckles, belt connectors, or accessories such as whistles.

[0106] The above embodiments are for illustration only. A person skilled in the art in the art to which the above embodiments belong can understand that the present invention can be easily changed into other specific forms without changing the technical ideas or essential features of the above embodiments. Therefore, the above embodiments should be understood as illustrative rather than restrictive in all aspects.

[0107] The scope to be protected by this specification is presented by the scope of protection of the invention described later, rather than by the above detailed description, and should be interpreted as including all changes or deformations derived from the meaning, scope and equivalent concepts of the scope of protection of the invention.
