A slider and zipper for double-sided use

Abstract

This invention discloses a double-sided zipper pull, relating to the field of zipper technology. The zipper pull body has a connecting post at its head end, and a pull tab assembly is mounted on the connecting post. The extension direction of the connecting post is parallel to the movement direction of the zipper pull. The pull tab assembly can rotate around the axis of the connecting post. As the pull tab assembly rotates to different positions on the zipper pull body, and because the thickness of the connecting post is less than the thickness of the zipper pull body, the pull tab assembly can fit against the outer surface of either the first or second base plate of the zipper pull body. The connecting post does not protrude beyond the outer surfaces of the first or second base plates of the zipper pull body, reducing the pressure of irregular protrusions on the body and improving wearing comfort.

DETAILED DESCRIPTION

[0036] The core of the present application is to provide a double-sided puller with smaller thickness, reducing the pressure of irregular protrusions on the body, and improving the comfort of wearing.

[0037] In order to enable those skilled in the art to better understand the technical solutions of the present application, the double-sided puller and the zipper of the present application will be described in detail below in combination with the drawings and specific embodiments.

[0038] In combination with Figure 3 , Figure 4 , Figure 5 , the present application provides a double-sided puller, which comprises a puller body 1, the puller body 1 is used to cooperate with the chain teeth, and can close or open two chain teeth, the movement direction of the puller body 1 during use is shown by the double-headed arrow in Figure 4 . The head end of the puller body 1 (lower right in Figure 4 ) is provided with a connecting column 2, the extension direction of the connecting column 2 is parallel to the movement direction of the puller, and the extension direction of the connecting column 2 is along the X-axis direction. The thickness of the connecting column 2 is smaller than the thickness of the puller body 1, the thickness direction is the Z-axis direction in the figure, in combination with Figure 7 , d1 is the thickness of the connecting column 2, d2 is the thickness of the puller body 1, the connecting column 2 does not protrude out of the puller body 1 in the thickness direction, that is, in the Z-axis direction, the connecting column 2 is located in the puller body 1.

[0039] The puller piece assembly 3 is installed on the connecting column 2, the puller piece assembly 3 can rotate around the rotation shaft of the connecting column 2, the axis direction of the connecting column 2 is the X-axis direction, the puller piece assembly 3 rotates around the X-axis direction, and the optimal case is that the puller piece assembly 3 can rotate by 360 degrees at any angle.

[0040] In the case where the puller piece assembly 3 does not need to be pulled, the puller piece assembly 3 can be attached to the outer surface of the first bottom plate 11 or the outer surface of the second bottom plate 12 of the puller body 1, the puller body 1 can adopt a symmetrical structure, in combination with Figure 7 , Figure 9The first base plate 11 and the second base plate 12 are symmetrical in structure, and they cooperate to clamp the chain teeth. For reversible garments, either the outer side of the first base plate 11 or the outer side of the second base plate 12 faces outward. Normally, the pull tab assembly 3 is close to the outward-facing side when not in use.

[0041] The pull tab assembly 3 is used for hand gripping in use. The pull tab assembly 3 provides pulling force to the zipper head body 1, causing the zipper head body 1 to move along the chain teeth, thereby achieving the engagement or disengagement of the chain teeth.

[0042] Because the present invention utilizes the pull tab assembly 3 to rotate around the connecting column 2 to achieve double-sided use, when not in use, the pull tab assembly 3 is attached to the outer surface of the first base plate 11 or the outer surface of the second base plate 12. The thickness of the connecting column 2 is less than the thickness of the zipper head body 1, and the connecting column 2 does not protrude from the outer surface of the zipper head body 1 in the thickness direction. Compared with traditional double-sided zipper heads, the present invention can avoid the formation of a protruding structure on the outer surface of the zipper head body 1, thereby reducing the pressure of irregular protrusions on the body and improving the comfort of wearing.

[0043] Based on the above scheme, combined with Figure 3 , Figure 4 , Figure 5 The pull tab assembly 3 of the present invention includes a connector 31 and a pull tab 32. The connector 31 is hinged to the connecting column 2 and can rotate relative to the connecting column 2 about the Z-axis. The head end of the pull tab 32 is rotatably engaged with the connector 31, and the tail end of the pull tab 32 can approach or move away from the pull head body 1. The tail end of the pull tab 32 is used for finger gripping, and the head end of the pull tab 32 can be rotatably engaged with the connector 31. The rotation axis of the pull tab 32 relative to the connector 31 is along the Y-axis direction.

[0044] This invention provides a specific configuration scheme for the pull tab assembly 3:

[0045] Combination Figure 4 , Figure 5 , Figure 7 The connector 31 includes a rotating connecting plate 311 and a connecting block 312. The surface of the rotating connecting plate 311 extends along the YZ plane. The rotating connecting plate 311 is rotatably connected to the connecting column 2 and is perpendicular to the axis of the connecting column 2. The rotating connecting plate 311 can rotate relative to the connecting column 2 around the X-axis. The connecting block 312 protrudes vertically from the rotating connecting plate 311. The connecting block 312 and the rotating connecting plate 311 form an "L"-shaped hook structure. The inner surface of the connecting block 312 is a cylindrical curved surface. The inner surface of the connecting block 312 is in contact with the connecting shaft 324.

[0046] The pull tab 32 includes a gripping tab 321, a transition tab 322, and a reset tab 323 connected in sequence. The three are connected end to end. The gripping tab 321 and the reset tab 323 are perpendicular to each other. The transition tab 322 has an inclined shape with an intermediate transition. A connecting shaft 324 is provided at the connection between the transition tab 322 and the reset tab 323. The length direction of the connecting shaft 324 is the Y-axis direction. The connecting shaft 324 can be hooked onto the connecting block 312. The connecting shaft 324 and the inner surface of the connecting block 312 form a rotational fit.

[0047] Combination Figure 5 The pull tab assembly 3 also includes an elastic element 33, located between the head end of the pull tab body 1 and the reset piece 323. The elastic element 33 can apply a reset force to the reset piece 323. When the pull tab 32 is installed in place, the elastic element 33 contacts the head end of the pull tab body 1 and the reset piece 323, applying an elastic force to the reset piece 323, causing the reset piece 323 to tend to move closer to the rotating connecting plate 311. When the reset piece 323 is close to the rotating connecting plate 311, the gripping piece 321 adheres to the outer surface of the pull tab body 1, that is, adheres to the first base plate 11 or the second base plate 12. This ensures that the pull tab 32 does not wobble and can rebound, preventing loss of locking force during movement.

[0048] Specifically, the holding piece 321 and the transition piece 322 form an obtuse angle, and the transition piece 322 and the reset piece 323 form an obtuse angle, so that a smooth transition is formed between the holding piece 321, the transition piece 322 and the reset piece 323.

[0049] Combination Figure 4 , Figure 5 The transition piece 322 is provided with a notch to avoid the connecting block 312, and the connecting shaft 324 is disposed in the notch of the connecting block 312. When the tail end of the pull tab assembly 3 is pulled upward, the connecting block 312 extends into this notch to avoid interference. It should be noted that providing a notch on the transition piece 322 is not necessary. If necessary, the connecting shaft 324 can also protrude from the surface of the transition piece 322 and form a certain gap. These specific forms should all be included within the protection scope of this invention.

[0050] The reset piece 323 is designed to avoid the notch in the connecting column 2, combined with Figure 4 , Figure 5 In this invention, the notch of the reset piece 323 is a U-shaped unsealed notch, through which the connecting post 2 can pass.

[0051] Combination Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9The outer surfaces of the first base plate 11 and the second base plate 12 are respectively provided with relief grooves 13 for accommodating the grip piece 321. The length of the relief groove 13 extends along the X-axis, and the two ends of the X-axis are not enclosed. The depth (Z-axis direction) of the relief groove 13 is greater than or equal to the thickness of the grip piece 321. When the grip piece 321 is embedded in the relief groove 13, the grip piece 321 does not protrude from the outer surfaces of the first base plate 11 and the second base plate 12 at all, making the outer surface of the entire zipper head flatter and further reducing the degree of protrusion. The grip piece 321 is embedded in the zipper head body 1, which can avoid collisions that cause wear to the zipper head. Of course, if the outer surfaces of the first base plate 11 and the second base plate 12 are not provided with relief grooves 13, the height of the entire zipper assembly 3 protruding from the outer surfaces of the first base plate 11 or the second base plate 12 is only the thickness of the grip piece 321, and will not create excessive pressure. Therefore, this form should also be included within the protection scope of this invention.

[0052] Combination Figure 4 , Figure 5 , Figure 6 A positioning pin 325 protrudes from the side of the grip piece 321 facing the slider body 1. The positioning pin 325 is perpendicular to the surface of the grip piece 321 and faces the slider body 1. The positioning pin 325 can be wedge-shaped, and the width of the fixed end of the positioning pin 325 is greater than the width of the protruding end to facilitate insertion into the positioning hole 131. A positioning hole 131 is provided in the clearance groove 13 to cooperate with the positioning pin 325 for insertion and positioning. The positioning hole 131 is a through hole or blind hole in the Z-axis direction to accommodate the positioning pin 325. When the positioning pin 325 is inserted into the positioning hole 131, it ensures that the grip piece 321 is exactly aligned with the clearance groove 13, which can prevent the grip piece 321 from moving out of the clearance groove 13 during daily activities.

[0053] Combination Figure 5 The elastic element 33 of the present invention includes a positioning piece 331 and two spring pieces 332. The surface of the positioning piece 331 is along the YZ plane, and the positioning piece 331 is provided with a through hole for inserting and connecting the column 2. The two spring pieces 332 are respectively connected to the two ends of the positioning piece 331 and form an acute angle with the positioning piece 331. The elastic element 33 is equivalent to bending the two ends of a strip plate. The end of the spring piece 332 is provided with a notch for avoiding the connection column 2. The notch provided in the spring piece 332 is a U-shaped non-closed notch. The elastic element 33 applies an elastic force to the pull tab assembly 3.

[0054] Furthermore, the head end of the slider body 1 of the present invention is provided with a positioning groove 14. The positioning groove 14 is a recessed groove along the X-axis direction. The positioning piece 331 can be embedded in the positioning groove 14. The positioning groove 14 is used to limit the positioning piece 331 to prevent rotation. Figure 7As shown, when the pull tab assembly 3 rotates 180 degrees, it changes from facing the first base plate 11 to facing the second base plate 12. The elastic element 33 keeps it fixed, and the two spring pieces 332 provide elastic force to the pull tab assembly 3 respectively. In the non-use state, the elastic force makes the grip piece 321 automatically adhere to the surface of the pull head body 1.

[0055] In addition to the solutions provided above, this invention provides another specific configuration of the pull tab assembly 3: the pull tab 32 is hinged to the connector 31. This structure is not shown in the accompanying drawings. In this structure, the pull tab 32 is connected to the connector 31 via a pivot, allowing the pull tab 32 to swing. This structure should also be included within the scope of protection of this invention. In this structure, clearance grooves 13, elastic elements, and other structures can also be provided.

[0056] The zipper pull structure provided by this invention allows for double-sided use through rotation of the pull tab assembly 3. It features locking force, is thinner and lighter, and allows for diverse pull tab designs. When used on clothing, it reduces potential pain from the zipper pull. The pull tab assembly 3 is stable and springs back, preventing the zipper pull from losing its locking force during movement. The zipper pull body has no protruding parts, making it safer than existing guide rail zipper pulls. The grip piece 321 is embedded in the zipper pull body, preventing wear and tear from impacts.

[0057] The present invention also provides a zipper including the aforementioned double-sided zipper pull, which achieves the same technical effect. For the other structural components of this zipper, please refer to the prior art; further details are omitted here.

[0058] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
