Description

Technical Field

[0001] This invention relates to a durable connector for jewelry. More specifically, the connector is designed to insert and support a fastening part that performs a swinging motion in a receiving groove, thereby improving the connector's durability, enhancing ease of use, and solving the problem of hand cuts that occur when users connect jewelry using the connector. Background Technology

[0002] Necklaces typically have clasps for adjustment or removal to fit the user's body size. Figure 9 This is a photo of a regular necklace clasp product.

[0003] In existing necklace clasp products, when the user applies pressure to the protruding part 1 of the clasp, the fastening part 3, which forms a component with the protruding part 1, rotates in the same direction as the protruding part 1. This creates a gap at the clasp end 2, which is away from the main body. The necklace with the loop on the opposite side is inserted into this gap and fastened to the clasp part of the main body. Afterward, when the user releases the protruding part, it returns to its original position due to the spring, causing the fastening part 3 and the clasp end 2 of the main body to re-contact and form a closed area. This ensures that the necklace with the loop on the opposite side is connected without detaching from the clasp.

[0004] However, because existing necklace clasps form a closed area through close contact between the fastening part 3 and the clasp end part 2, if a part bends due to frequent use, the closed area cannot be formed, often rendering it unusable as a clasp. Furthermore, if the user applies force to straighten the bent part, the corresponding part may break and become irreparable. In short, it suffers from very poor durability. Additionally, bending can cause the closed area to disappear, leading to the detachment of necklaces and other jewelry, resulting in the loss of expensive pieces.

[0005] In addition, because the clasp of the necklace is fragile in such a bending situation, it is inevitable to reduce the purity of the gold to increase its rigidity, thus causing a decrease in the overall quality of the necklace.

[0006] In addition, such as Figure 9 As shown, since the fastening part 3 has a rotating structure, an inclined surface is inevitably formed in order to minimize friction with the buckle end part 2 of the main body and to enable rotation. Complementing this, the buckle end part 2 of the main body also necessarily forms an inclined surface. Therefore, a sharp structure is formed at the end of the inclined surface, and since users usually use the fastener with their hands behind their backs and out of sight, hand cuts occur frequently during use due to the sharp parts.

[0007] Additionally, sharp parts can snag on a user's clothing, causing damage such as tearing or stretching. Summary of the Invention

[0027] The following description is merely illustrative of the principles of the invention. Therefore, although not explicitly described or shown in this specification, those skilled in the art can implement the principles of the invention and invent various devices included within the concept and scope of the invention. Furthermore, all terms and embodiments listed in this specification are intended only to help understand the concept of the invention and should be understood as not being limited to the embodiments and states specifically listed above.

[0028] Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0029] Figure 1 This is a perspective view showing the connector for jewelry according to the present invention. Figure 2 This is a diagram illustrating the operation process of the connector for jewelry according to the present invention. Figure 3 This is an exploded perspective view showing the connector for jewelry according to the present invention. Hereinafter, refer to... Figures 1 to 3 The structure and effects of the connector for jewelry according to the present invention will be described.

[0030] The connector for jewelry according to the present invention includes a main body 100, a buckle 200, a swinging part 300, and a torsion spring part 400.

[0031] The main body 100 includes a housing 110 and a shaft 120. The housings 110 are formed as a pair, spaced apart in the width direction by a predetermined interval, and are formed to extend downward in the vertical direction. One end of a necklace is attached to the lower part of the housing 110.

[0032] Preferably, a shaft 120 is coupled between a pair of housings 110 along the width direction. As an example, the shaft 120 is coupled to only one housing 110, and the end of the shaft 120 is spaced apart from the other housing 110 by a predetermined interval, thereby facilitating the engagement and disengagement of the fastener 200. Furthermore, as described later, a shaft hole 340 is provided in the shaft 120, so the fastener 200 can swing about the main body 100. More specifically, the fastener 200 swings about the shaft 120.

[0033] The fastener 200 is engaged with the main body 100. The fastener 200 includes a bridging portion 210 and a receiving portion 220. One end of the bridging portion 210 is engaged with the main body 100, and the receiving portion 220 extends from the other end. Preferably, the bridging portion 210 is, for example, in the shape of a round buckle, and the extended receiving portion 220 is spaced apart from the main body 100 by a predetermined interval. The specific structure of the receiving portion 220 will be described later.

[0034] The swinging part 300 is combined with the main body 100, enabling it to swing around the main body 100. The swinging part 300 includes a base 310, a fastening part 320, and a pressing part 330.

[0035] Preferably, the base 310 is joined by inserting between a pair of housings 110 of the main body 100, so that the entire swinging part 300 can swing without detaching from the main body 100.

[0036] A shaft hole 340 protruding in the width direction is formed in the base 310, and a hollow portion 341 is formed in the shaft hole 340 in the width direction. The shaft 120 of the base 310 is connected to the hollow portion 341. Due to this structure, the base 310 can swing about the shaft 120.

[0037] A pressing portion 330 extends from one end of the base 310. The pressing portion 330 protrudes from the main body 100, and the user applies pressure to the pressing portion 330. Preferably, the pressing portion 330 is rounded. Therefore, during use, sharp parts are minimized, thereby minimizing the problem of the user being cut by the pressing portion 330.

[0038] A fastening portion 320 is formed at the other end of the base 310. The specific structure of the fastening portion 320 will be described later. At this time, when the user does not apply pressure to the pressing portion 330, the fastening portion 320 is accommodated in the receiving portion 220. When the user applies pressure to the pressing portion 330, the pressing portion 330 moves about the axis 120. Figure 3 The fastening part 320, housed in the receiving part 220, rotates counterclockwise relative to the reference point, and correspondingly, rotates counterclockwise and disengages from the receiving part 220. This creates a gap between the fastening part 320 and the receiving part 220, allowing the loop formed at the other end of the necklace to be inserted into the gap and into the bridging part 210. Subsequently, when the user no longer applies pressure to the pressing part 330, as described later, the pressing part 330 rotates clockwise by the elastic restoring force of the torsion spring part 400. Correspondingly, the fastening part 320 also rotates clockwise to return to its original position and is housed in the receiving part 220. This creates a closed area, preventing the other end of the necklace from detaching from the connector according to the invention, thus functioning as a connector.

[0039] As described above, the conventional structure, where the end portion 2 and the fastening portion 3 are separated by a small gap, suffers from the following problems: bending occurs with continued use, reducing durability, and a sloping surface is formed due to the radius of rotation, potentially causing the user's hand to be cut by sharp parts. However, since the present invention features a structure where the fastening portion 320 is housed within the receiving portion 220 rather than being separated, the receiving portion 220 supports the fastening portion 320, minimizing the exposure of the fastening portion 320 to the outside, thus minimizing bending. As explained in detail below, since the structure does not form a sharp sloping surface across the entire connector, it fundamentally eliminates the problem of user hand cuts. Furthermore, unlike the past, rigidity is not ensured by reducing the purity of gold, thus improving the overall product quality.

[0040] The torsion spring portion 400 is inserted between the shaft hole 340 and the base 310, more specifically, between a pair of housings 110. Due to the structure of the torsion spring portion 400, when the pressing portion 330 is pressed and oscillated and then no longer pressed, the oscillating portion 300 can return to its position without additional external force due to the elastic restoring force, thus improving ease of use.

[0041] Reference Figure 7 , Figure 7 This is a magnified view of the inner part of the bridging section 210.

[0042] A through groove 212 is formed at the position where the bridging portion 210 connects to the main body portion 100, and the pressing portion 330 of the swing portion 300 passes through the through groove 212. Therefore, the pressing portion 330 can swing without interfering with the bridging portion 210 of the fastener portion 200.

[0043] Preferably, a pair of support members 211 are formed at a position inside the bridging portion 210. The support members 211 include a first support member 2111 and a second support member 2112. The first support member 2111 extends inside the bridging portion 210, and the second support member 2112 extends from the inner end of the first support member 2111. Preferably, the second support member 2112 and the first support member 2111 have different lengths in the width direction; more specifically, the length of the second support member 2112 in the width direction is preferably longer than the length of the first support member 2111 in the width direction. The end of a torsion spring portion 400 is inserted between the pair of support members 211, thus fixing the torsion spring portion 400 to the buckle portion 200. At this time, when the length of the second support member 2112 in the width direction is longer than the length of the first support member 2111 in the width direction, due to the structure in which the spacing between the pair of support members 211 gradually narrows inward (more specifically, in the direction of axis 120), the possibility of the end of the torsion spring portion 400 detaching from the pair of support members 211 is minimized, thereby having the advantage of improved durability.

[0044] Figure 4 This is an enlarged view showing the receiving portion 220 of the present invention. Figure 5 This is a front view showing the fastening part 320 of the present invention. Figure 6 This is a side view showing the fastening part 320 of the present invention. Additionally, Figure 8 This shows the state when the fastening part 320 is accommodated in the receiving part 220.

[0045] First, the fastening part 320 will be described. The fastening part 320 includes a first fastening part 321 and a second fastening part 322. The direction from the first fastening part 321 to the second fastening part 322 is from the top to the bottom in the vertical direction.

[0046] The first fastening portion 321 is formed to extend downward in the vertical direction and along the length direction, and its length in the width direction is greater than that of the second fastening portion 322 in the width direction. Therefore, due to the difference in length in the width direction between the first fastening portion 321 and the second fastening portion 322, a step 3211a in the width direction is formed at the lower part of the first fastening portion 321. Furthermore, the second fastening portion 322 is formed to extend downward in the vertical direction and along the length direction, and its length in the width direction is shorter than that of the base portion 310 in the width direction, and it is preferably connected to the base portion 310. Therefore, when the entire fastening portion 320 is viewed from the front, it has a "T" shape. Thus, since the fastening portion 320 and the receiving portion 220 are fastened with a "guide rail-guide groove" structure, and a structure capable of sliding movement is formed, the stability of the connection between the two components is improved, insertion and disassembly are easy, and due to the smooth insertion and disassembly through sliding action, it has the advantages of less wear and increased durability.

[0047] Furthermore, preferably, the corners of the first fastening portion 321 are rounded, and correspondingly, a rounded portion is also formed at the complementary position of the receiving portion 220. Therefore, wear is minimized, thereby improving durability.

[0048] Furthermore, an arcuate portion 323 is formed at the connection between the second fastening portion 322 and the base portion 310, such as Figure 5 As shown, the arc portion 323 is preferably arc-shaped along its length. Therefore, wear during the insertion or removal of the second fastening portion 322 into or from the receiving portion 220 is minimized, and durability is improved. Correspondingly, preferably, an arc portion 225 is also formed at a complementary location to the receiving portion 220. This will be described in detail later.

[0049] Reference Figure 6 and Figure 8 For ease of explanation, the fastening part 321 will be described in two parts: a front surface part and a rear surface part. A first fastening part front surface 3211 and a second fastening part front surface 3221 are formed on the front surface part of the fastening part 320, and a first fastening part rear surface 3212 and a second fastening part rear surface 3222 are formed on the rear surface part.

[0050] In addition, for ease of explanation, the step is also divided into the front surface 3211a and the rear surface 3212a, and the arc portion 323 is also divided into the front surface 3231 and the rear surface 3232.

[0051] At this point, preferably, the rear surface 3212 of the first fastening part protrudes beyond the rear surface 3222 of the second fastening part in the length direction, and preferably, the boundary between the rear surface 3212 of the first fastening part and the rear surface 3212a of the step is arc-shaped to protrude downward in the vertical direction. Unlike the front surface 3211 of the first fastening part and the front surface 3221 of the second fastening part, refer to... Figure 6 and Figure 8 The rear surface 3212 of the first fastening part protrudes longer than the rear surface 3222 of the second fastening part in the longitudinal direction and downward in the vertical direction, thus having a "hook" shape. This improves support stability when received in the receiving part 220, thereby minimizing the possibility of the entire fastening part 320 detaching from the receiving part 220. In addition, due to its arc shape, durability can be improved by minimizing wear.

[0052] Conversely, the lengths of the first fastening front surface 3211 and the second fastening front surface 3221 are almost identical in the longitudinal direction. Since the first fastening front surface 3211 and the second fastening front surface 3221 have shapes that are exposed to the outside even when housed in the receiving portion 220, it is preferable to minimize the step in the longitudinal direction, and to prevent the following problem: if the step in the longitudinal direction is formed to be slightly large, the step portion may snag clothing or cut the user's body.

[0053] Additionally, refer to Figure 6 and Figure 8 Unlike the front surface 3221 of the second fastening part, the rear surface 3222 of the second fastening part is arc-shaped in the vertical direction. During the entire process of the fastening part 320 being accommodated in the receiving part 220, the rear surface 3222 of the second fastening part contacts a specific position 226 of the receiving part 220 (described later), at which point it is arc-shaped in the vertical direction, thereby achieving a shape that wraps around the specific position 226. Therefore, wear can be minimized and durability improved.

[0054] Based on a similar principle, the rear surface 3212 of the first fastening part is also arc-shaped in the vertical direction and has the above-mentioned effect.

[0055] Secondly, refer to Figure 4 The description of the housing section 220 is as follows.

[0056] Preferably, the receiving portion 220 includes a receiving groove formed in a shape complementary to that of the fastening portion 320. For ease of explanation, the receiving groove is divided into a first receiving groove 226 and a second receiving groove 227 according to its position.

[0057] The first receiving groove 226 includes a first receiving portion 222 and a first receiving portion 223. The first receiving portion 222 receives the first fastening portion 321, and the first receiving portion 223 receives steps 3211a and 3212a. The second receiving groove 227 includes a second receiving portion 224 and a second receiving portion 225. The second receiving portion 224 receives the second fastening portion 322, and the second receiving portion 225 receives the arcuate portion 323. As described above, the receiving portion 220 receives the fastening portion 320.

[0058] At this time, as described above, the length of the first receiving groove 226 in the longitudinal direction is preferably longer than the length of the second receiving groove 227 in the longitudinal direction. Due to this step in the longitudinal direction, the hook portion of the first fastening part 3212 is supported by the step in the longitudinal direction, thereby improving the fastening support and stability when the fastening part 320 and the receiving part 220 are combined.

[0059] Figure 8 This is an enlarged view showing the fastener 320 being accommodated in the receiving groove.

[0060] Preferably, the present invention is designed such that when the fastening part 320 is received in the receiving groove, the portions of the fastening part 320 and the receiving groove opposite to each other are separated by a predetermined interval, and the interval narrows from the front surface of the receiving groove towards the rear surface. Figure 8 Based on the reference point, the spacing indicated by the attached reference numeral "a" is used as the reference, and the spacing becomes narrower towards the reference numerals "b" and "c".

[0061] The action of the fastening part 320 swinging and being received in the receiving groove is an action in which the fastening part 320 is inserted and received sequentially from the front surface to the rear surface of the receiving groove. Therefore, it is designed such that at the initial moment when the fastening part 320 begins to be inserted into the receiving groove, a slight gap is maintained between the receiving groove and the fastening part 320 to facilitate the insertion of the fastening part 320, and when the fastening part 320 is fully inserted, the gap is minimized to minimize the possibility of the fastening part 320 disengaging. Therefore, it has the advantages of improved ease of use and durability.

[0062] Furthermore, although preferred embodiments of the present invention have been shown and described above, the present invention is not limited to the specific embodiments described above. Various modifications can be made by those skilled in the art without departing from the spirit of the invention as claimed in the claims, and such modifications should not be understood independently of the technical concept or prospect of the present invention.
