Description

Technical Field

[0001] The present invention relates to a fastener, and particularly to a sliding fastener. Background Art

[0002] For general articles (such as shoes, clothing, etc.), in order to facilitate the adjustment of tightness, the method of using magic tape (or hook-and-loop fastener) is often adopted to facilitate the user to adjust the required tightness. However, this method requires repeatedly pulling open and sticking the magic tape to adjust to the appropriate position, and the magic tape is easily damaged during this process. At this time, the magic tape needs to be replaced, and the replacement process is quite time-consuming and costly, and it is very inconvenient to use. Summary of the Invention

[0003] The object of the present invention is to provide a sliding fastener to solve at least one of the above problems.

[0004] The present invention provides a sliding fastener, comprising: a first fastener including a seat body, a slide rail portion and a plurality of positioning grooves, wherein the slide rail portion extends outward from the seat body, and the positioning grooves are recessed from the slide rail portion and are spaced apart from each other; and a second fastener which is assembled with the first fastener and includes a body, an elastic portion, a tooth portion and a slider portion, wherein the elastic portion extends outward from the body, the tooth portion extends outward from the elastic portion, the slider portion extends outward from the body and is connected to the slide rail portion and can slide relative to the slide rail portion; wherein the elastic portion can be transformed between a fastening state and a loosening state, so that in the fastening state, the tooth portion is received in the positioning grooves, making the second fastener unable to move in a loosening direction, and in the loosening state, the tooth portion disengages from the positioning grooves, making the second fastener able to move in the loosening direction.

[0005] In the sliding fastener as described above, the tooth portion has an inclined surface, each of the positioning grooves has a pushing surface, the inclined surface corresponds to the pushing surface, and the inclined surface is obliquely intersecting with the surface of the elastic portion, and the pushing surface is obliquely intersecting with the surface of the slide rail portion.

[0006] In the sliding fastener as described above, the pushing surface faces the loosening direction, and the inclined surface faces away from the loosening direction.

[0007] In the sliding fastener as described above, the tooth portion further has a stop surface, each of the positioning grooves further has a vertical surface, the stop surface corresponds to the vertical surface, and the stop surface is perpendicular to the surface of the elastic portion, and the vertical surface is perpendicular to the surface of the slide rail portion, so that the second fastener is limited by the stop surface and the vertical surface and cannot move in the loosening direction.

[0008] In the sliding fastener as described above, the elastic portion is bent to disengage the tooth portion from the positioning grooves.

[0009] As in the aforementioned sliding fastener, the first fastener also includes a first stop block and a second stop block. The first stop block extends outward from the base body and is connected to one end of the slide rail portion, and the second stop block extends outward from the base body and is connected to the other end of the slide rail portion.

[0010] As in the aforementioned sliding buckle, the first stopper and the second stopper are arranged in sequence along the loosening direction.

[0011] As in the aforementioned sliding buckle, the width of the first stopper is greater than the width of the second stopper.

[0012] As in the aforementioned sliding fastener, the slide rail portion has corresponding upper slide rails and lower slide rails, and the slider portion has an upper slider, a lower front slider and a lower rear slider. The upper slider is slidably arranged on the upper slide rail, the lower front slider is spaced apart from the lower rear slider, and the lower front slider and the lower rear slider are slidably arranged on the lower slide rail.

[0013] As in the aforementioned sliding buckle, the distance between the upper slider and the lower front slider is smaller than the width of the first stopper and is therefore limited by the first stopper.

[0014] As in the aforementioned sliding buckle, the slider portion also has two stop arms, which are respectively extended outward from the upper slider and the lower rear slider and correspond to each other, and the distance between the stop arms is smaller than the width of the second stop block and is limited by the second stop block.

[0015] As in the aforementioned sliding fastener, the second fastener further includes a coupling portion, which is connected to the body and is used to couple with an object.

[0016] As in the aforementioned sliding buckle, the body, the elastic portion, the tooth portion, the slider portion and the coupling portion are integrally formed.

[0017] As in the aforementioned sliding fastener, when the second fastener moves in a direction opposite to the loosening direction, the inclined surface and the pushing surface are misaligned, and the elastic portion is deformed by force to cause the tooth portion to disengage from the positioning groove, and the elastic portion does not rebound until the tooth portion slides into the next adjacent positioning groove.

[0018] In summary, the sliding clip of the present invention utilizes the design of the teeth and positioning grooves to provide a one-way stop. Furthermore, the elastic portion can be easily bent to release the one-way sliding restriction. The sliding clip of the present invention has a low component count, low manufacturing cost, and a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] Please refer to Figure 1 and Figure 2 , the sliding fastener 100 of the present invention includes a first fastener 1 and a second fastener 2, and the first fastener 1 and the second fastener 2 can be assembled with each other.

[0059] The first fastener 1 includes a seat body 11, a slide rail part 12, nine positioning grooves 13, a first stop block 14 and a second stop block 15. The seat body 11 is generally in the shape of a long rectangular plate body with rounded corners and can be coupled to an article, which can be, for example, footwear (can be coupled to the side of a shoe, etc.), but the present invention is not limited thereto. The slide rail part 12 extends outward from the seat body 11 and generally has a T-shaped cross-section, and has a surface 120, an upper slide rail 121 and a lower slide rail 122. Please refer to Figure 7 , the positioning grooves 13 are recessed from the surface 120 of the slide rail part 12 and are spaced apart from each other, and each positioning groove 13 has a pushing surface 131 and a vertical surface 132 respectively. The pushing surface 131 intersects obliquely with the surface 120 of the slide rail part 12, and the vertical surface 132 is perpendicular to the surface 120 of the slide rail part 12. The first stop block 14 extends outward from the seat body 11 and is connected to one end of the slide rail part 12. The second stop block 15 extends outward from the seat body 11 and is spaced apart from the first stop block 14, and is connected to the other end of the slide rail part 12.

[0060] In this embodiment, please refer to Figure 8 , the first stop block 14 and the second stop block 15 are arranged in sequence along the loosening direction X, and the width W1 of the first stop block 14 is greater than the width W2 of the second stop block 15.

[0061] Please also refer to Figure 2 、 Figure 3 and Figure 4 . The second fastener 2 includes a body 21, an elastic portion 22, a tooth portion 23, a slider portion 24, a coupling portion 25 and a limit cover 26.

[0062] The body 21 is generally in the shape of a U-shaped block. The elastic portion 22 extends outward from the body 21 (for example, extends outward from the recess of the U-shaped block). The tooth portion 23 extends outward from the elastic portion 22 (facing the first fastener 1), and has an inclined surface 231 and a stop surface 232. As Figure 7 shown, the inclined surface 231 corresponds to the pushing surface 131, and the inclined surface 231 intersects obliquely with the surface 221 of the elastic portion 22. The stop surface 232 corresponds to the vertical surface 132, and the stop surface 232 is perpendicular to the surface 221 of the elastic portion 22.

[0063] The slider portion 24 extends outward from the body 21 and is connected to the slide rail portion 12, and can slide relative to the slide rail portion 12. The body 21 and the slider portion 24 specifically have a C-shaped cross-section, and the C-shaped cross-section can match the T-shaped cross-section of the slide rail portion 12. Specifically, the slider portion 24 has an upper slider 241, a lower front slider 242, a lower rear slider 243 and two retaining arms 244. The upper slider 241 slides on the upper slide rail 121 (that is, the upper slide rail 121 is clamped between the upper slider 241 and the body 21). The lower front slider 242 and the lower rear slider 243 are spaced apart and are respectively located on opposite sides of the elastic portion 22, and the lower front slider 242 and the lower rear slider 243 slide on the lower slide rail 122 (that is, the lower slide rail 122 is clamped between the lower front slider 242 and the body 21 and between the lower rear slider 243 and the body 21). The two retaining arms 244 respectively extend outward from the upper slider 241 and the lower rear slider 243 and correspond to each other, and the two retaining arms 244 extend outward in a manner of approaching each other. The coupling portion 25 is generally in a ring shape, is connected to the body 21, and is used to couple an object, such as a webbing, a cord or a fabric, etc. That is, the coupling portion 25 can be attached with a webbing loop or a sewing piece, etc. The limit cover 26 is disposed outside the body 21 and is spaced apart from the elastic portion 22 to limit the elastic portion 22.

[0064] In this embodiment, as Figure 8 and Figure 9 shown, there is a distance D1 between the upper slider 241 and the lower front slider 242, and the distance D1 is less than the width W1 of the first stopper 14. There is a distance D2 between the ends of the two retaining arms 244, and the distance D2 is less than the width W2 of the second stopper 15.

[0065] In one embodiment, the body 21, the elastic part 22, the tooth part 23, the slider part 24 and the joint part 25 are integrally formed, for example, injection molded with an elastic plastic material, but the present invention is not limited thereto.

[0066] The way the first fastener 1 and the second fastener 2 are assembled with each other in the sliding fastener 100 of the present invention is as follows. First, the upper slider 241 and the lower front slider 242 on the second fastener 2 are abutted against the second stop block 15. The second stop block 15 has an inclined surface, which can easily allow the upper slider 241 and the lower front slider 242 to pass through the second stop block 15 after being slightly squeezed, and at the same time, the two retaining arms 244 also pass through the second stop block 15 after being slightly squeezed. Since the distance D1 between the upper slider 241 and the lower front slider 242 is smaller than the width W1 of the first stop block 14, the upper slider 241 and the lower front slider 242 will be limited by the first stop block 14 and cannot pass through the first stop block 14. In addition, since the distance D2 between the ends of the two retaining arms 244 is smaller than the width W2 of the second stop block 15, the two retaining arms 244 will be limited by the second stop block 15 and cannot pass through the second stop block 15, which makes the second fastener 2 unable to disengage from the first fastener 1 and thus completes the assembly.

[0067] The actuation method of the sliding fastener 100 of the present invention is as follows. After the first fastener 1 and the second fastener 2 are assembled, the tooth part 23 is received in one of the positioning grooves 13, that is, the elastic part 22 is in a buckled state, as Figure 5 and Figure 7 shown. At this time, the pushing surface 131 faces the loosening direction X, the inclined surface 231 faces away from the loosening direction X, and the second fastener 2 is limited by the stop surface 232 and the vertical surface 132 and cannot move relative to the first fastener 1 in the loosening direction X. However, the second fastener 2 can move in the direction opposite to the loosening direction X (or the tightening direction) by misaligning the pushing surface 131 and the inclined surface 231. At this time, the elastic part 22 is deformed by force, so that the tooth part 23 disengages from the positioning groove 13, and the elastic part 22 will rebound only when the tooth part 23 slides into the next adjacent positioning groove 13. This actuation can produce a tightening effect on the object coupled to the joint part 25, such as tightening a webbing, etc., and the closer the elastic part 22 is to the first stop block 14, the higher the tightening degree.

[0068] If it is necessary to loosen the object on the joint part 25, as Figure 6 shown, as long as the elastic part 22 is bent along the bending direction R to make the elastic part 22 in a loosening state, at this time the tooth part 23 disengages from the positioning groove 13, and the second fastener 2 is no longer limited by the stop surface 232 and the vertical surface 132, and can move in the loosening direction X. The closer the elastic part 22 is to the second stop block 15, the lower the tightening degree.

[0069] In summary, the sliding clip of the present invention utilizes the design of the teeth and positioning grooves to provide a one-way stop. Furthermore, the elastic portion can be easily bent to release the one-way sliding restriction. The sliding clip of the present invention has a low component count, low manufacturing cost, and a wide range of applications.
