Description

Technical Field

[0001] This invention relates to a zipper pull suitable for use on zippers, and more particularly to a simplified zipper pull suitable for use on zippers. Background Technology

[0002] The zipper pull is a key moving component of a zipper, used to engage and disengage the teeth on a pair of zipper straps. It typically includes an upper plate, a lower plate, and a connecting post connecting the upper and lower plates. A prominent "trunk" is positioned in the center of the upper plate, and a pull tab is mounted on the trunk. For example, a sliding block disclosed in Chinese Patent 200510005910.X includes a sliding block body molded from aluminum or zinc alloy, having a pull tab attachment portion (commonly referred to in the industry as the "trunk") mounted thereon, and a resilient pull tab molded onto the sliding block body from a resilient material such as an elastic thermoplastic resin, thermoplastic elastomer, or rubber. Either the pull tab attachment protrusion or the pull tab itself has a shaft formed therein, and the other has a hole formed therein. The shaft is fitted into the hole, such that the outer circumferential surface of the shaft is in close frictional contact with the inner circumferential surface of the hole. As a result, the pull bar can be held in any suitable position without swaying unnecessarily; it prevents the pull bar from colliding with other objects and causing clicking noises. Furthermore, the pull bar can be manipulated freely. A detailed analysis of this existing patent reveals that the pull bar attachment portion is isolated, occupying most of the area in the middle of the upper wing of the sliding block body. Very little empty space remains on the upper wing, making it impossible to place brand logos or decorative patterns on its surface. Therefore, decorative patterns are typically placed on the pull bar itself, requiring a large decorative surface, which makes the pull bar appear bulky. Summary of the Invention

[0003] To address the shortcomings of existing technologies, one of the objectives of this invention is to optimize the structure of the zipper pull to provide more diverse options for arranging brand logos and decorative patterns. Therefore, this invention proposes a simplified zipper pull suitable for zippers, comprising a main body slidably mounted on a pair of zipper straps to open or close them. The main body includes a wing plate, the left side of which bulges upward to form a raised platform, while the right side is recessed downward to form a low depression, thus giving the wing plate a stepped shape with a left-high-right-low profile. It also includes a movable pull tab rotatably connected to the raised platform, the axis of rotation of which extends in the front-back direction, allowing the pull tab to flip in the left-right direction.

[0004] Compared with the prior art, the beneficial technical effects of the present invention are as follows: First, since the wing plate is generally stepped with a left-high and right-low shape, there is no need to additionally set a high protrusion like an island-shaped elephant trunk on the wing plate. The high platform provides a base for the movable pull tab to be positioned on the wing plate, and at the same time, a continuous extending wall surface can be formed on the top wall of the high platform or the top wall of the low platform, providing layout space for setting brand logos and decorative patterns such as patterns on the pull head. Under this premise, the movable pull tab does not need to adopt a large volume structure for setting decorative patterns, which is conducive to the movable pull tab having a small volume and reducing the overall material consumption and weight of the movable pull tab. Second, the rotation axis of the movable pull tab extends in the front-back direction, so that the movable pull tab can be flipped in the left-right direction. In this way, no matter which angle the movable pull tab is flipped to, it will not stand horizontally above the high platform or low platform in the left-right direction and block the decorative patterns on the high platform or low platform, thus forming a visual defect of horizontally cutting off the decorative patterns.

[0005] A further technical solution could be that the elevated platform includes a mounting portion and a blocking portion, the movable pull tab is rotatably connected to the mounting portion and located on the right side of the blocking portion; the blocking portion can prevent the movable pull tab from falling over on the elevated platform.

[0006] A further technical solution may include a pair of blocking parts, the pair of blocking parts being disposed on the front and rear sides of the mounting part, and viewed from above, the mounting part protruding to the right relative to the pair of blocking parts; the movable pull tab includes a pair of front and rear supporting arms, the pair of supporting arms being rotatably connected to the front and rear sides of the mounting part and located on the right side of the blocking parts.

[0007] A further technical solution may be that the pull head also includes a rotating shaft, and a through hole extending in the front-to-back direction is provided on the raised platform. A pair of support arms of the movable pull tab are respectively provided with arm through holes extending in the front-to-back direction. The rotating shaft is inserted into both the arm through holes of the pair of support arms and the through holes. The rotating shaft is tightly fitted with the arm through holes and the through holes, so that the movable pull tab can be maintained at any angular position within the swing amplitude.

[0008] A further technical solution may include a pair of mounting portions, which are located on the front and rear sides of the blocking portion. Viewed from above, the pair of mounting portions protrude to the right relative to the blocking portion. The movable pull tab includes a support arm, which is rotatably connected between the pair of mounting portions and located on the right side of the blocking portion.

[0009] A further technical solution could be that the movable pull tab is semi-circular, including a pair of front and rear supporting arms and an intermediate connecting arm connecting the pair of supporting arms. The pair of supporting arms are rotatably connected to the high platform, and an inner ring gap is formed between the pair of supporting arms, the intermediate connecting arm and the high platform. When the movable pull tab is lying on the low depression, viewed from above, the pair of supporting arms rest on the low depression, and part of the inner ring gap extends beyond the main body.

[0010] A further technical solution could be that when the movable pull tab lies down on the low-lying area, when viewed from left to right, the height of the movable pull tab is basically the same as that of the high platform.

[0011] A further technical solution could be that when the movable pull tab lies down on the low-lying area, when viewed from left to right, the movable pull tab is essentially obscured by the high platform.

[0012] The present invention also proposes a zipper, characterized in that it includes a pair of chain straps and a simplified zipper pull suitable for use on the zipper, the simplified zipper pull being slidable on the pair of chain straps.

[0013] Because of the above-mentioned features and advantages, this invention can be applied to a simplified zipper pull and zipper suitable for use on zippers. Attached Figure Description

[0020] The following description, in conjunction with the accompanying drawings, further illustrates the structure of the simplified zipper pull and zipper applicable to zippers using the technical solution of the present invention. Except where explicitly stated to be equivalent or alternative embodiments, the various implementation details disclosed below may be selectively applied or combined in a single embodiment even if they are not directly related or synergistic in function.

[0021] like Figures 1-6 As shown, a simplified zipper pull suitable for use on zippers includes a main body 100, which is slidably mounted on a pair of zipper straps 5 to close or open the pair of straps. The main body 100 includes a wing plate 1, the left side wall of which protrudes upward to form a raised platform 11, while the right side wall is recessed downward to form a low depression 12, thus giving the wing plate 1 an overall stepped shape with the left side higher than the right. It also includes a movable pull tab 4, which is rotatably connected to the raised platform 11. The rotation axis Z of the movable pull tab 4 extends in the front-back direction, allowing the movable pull tab 4 to flip in the left-right direction.

[0022] The zipper 5 has a variety of structures; in this embodiment, for example... Figure 6 As shown, the zipper 5 includes a pair of chain straps, one of which is defined as the left chain strap 51 and the other as the right chain strap 52. Interlocking teeth 53 are provided on the inner sides of the pair of chain straps. For the specific structure of the teeth 53, please refer to the detailed descriptions of the teeth in prior patents CN201110451622.2 and CN200910112481.4. Other tooth structures can also be used. The main body 100 includes a pair of upper and lower wing plates 1 and a connecting post 2 connecting the pair of wing plates 1. A Y-shaped tooth channel is formed between the pair of wing plates 1 and the connecting post 2. When the main body 100 slides on the pair of chain straps, the teeth 53 on the pair of chain straps can interlock to close the pair of chain straps, or the interlocking teeth 53 can be separated to open the pair of chain straps.

[0023] In this embodiment, the left and right walls of the wing plate 1 are named according to their relative orientation. The wall on one side is defined as the left wall, and the opposite wall is defined as the right wall. The front-back direction and the left-right direction are not parallel but intersecting, for example, perpendicular. In this embodiment, the wall on the wing plate 1 closest to the left chain strap 51 is defined as the left wall, and the wall closest to the right chain strap 52 is defined as the right wall. The direction in which the zipper head slides on the zipper 5 is defined as the front-back direction.

[0024] The low-lying portion 12 is lower in height than the high-lying portion 11, and there is a certain height difference H between them. A recessed space bounded by the height H is formed above the low-lying portion 12.

[0025] According to the above technical solution, compared with the prior art, the technical effect of the present invention is as follows: First, since the wing plate 1 is generally stepped with the left side higher than the right side, it is not necessary to set a high protrusion like an island-shaped elephant trunk on the wing plate 1. The high platform 11 provides a base for the movable pull tab 4 to be positioned on the wing plate 1. At the same time, a continuous extending wall surface can be formed on the top wall of the high platform 11 or the top wall of the low depression 12, providing layout space for setting brand logos and decorative patterns such as patterns on the pull head. Under this premise, the movable pull tab 4 does not need to be set with a large volume structure for setting decorative patterns, which is conducive to the movable pull tab 4 adopting a small volume and reducing the overall material consumption and weight of the movable pull tab 4. Second, the rotation axis Z of the movable pull tab 4 extends in the front-back direction, so that the movable pull tab 4 can be flipped in the left-right direction. In this way, no matter which angle the movable pull tab 4 is flipped to, it will not remain horizontally above the high platform 11 or the low platform 12 in the left-right direction and block the decorative pattern on the high platform 11 or the low platform 12, thus forming a visual defect that horizontally cuts off the decorative pattern.

[0026] like Figure 1 and Figure 3 As shown, the elevated platform 11 includes a mounting portion and a blocking portion. The movable pull tab 4 is rotatably connected to the mounting portion and located on the right side of the blocking portion. The blocking portion prevents the movable pull tab 4 from falling onto the elevated platform 11. Thus, the movable pull tab 4 cannot obscure the brand logo or decorative patterns on the top wall of the elevated platform 11 by falling onto it. This helps to keep the decorative patterns visible, making them easy for the user to observe. It also helps to prevent the movable pull tab 4 from violently colliding with or scratching the decorative patterns during movement, thus protecting the decorative patterns. In specific applications, one of the following movable pull tab limiting technology solutions can be selected:

[0027] The first type of movable pull tab 4 limiting technology solution includes a pair of blocking parts (113, 114), which are respectively located on the front and rear sides of the mounting part 112. Viewed from above, the mounting part 112 protrudes to the right relative to the pair of blocking parts (113, 114). The movable pull tab 4 includes a pair of front and rear supporting arms 41, which are respectively rotatably connected to the front and rear sides of the mounting part 112 and located on the right side of the pair of blocking parts (113, 114).

[0028] In this embodiment, the first technical solution for limiting the movable tab is selected. As Figure 3 and Figure 5 shown, a pair of the blocking portions (113, 114) and the mounting portion 112 are combined into a "convex" shape. The slider further includes a rotating shaft 3. A table through-hole 110 extending in the front-rear direction is provided on the high platform portion 11. A pair of arm through-holes 44 extending in the front-rear direction are respectively provided on a pair of the arm portions 41 of the movable tab 4. The rotating shaft 3 is inserted through the arm through-holes 44 of the pair of the arm portions 41 and the table through-hole 110 at the same time. A tight fit is formed between the rotating shaft 3 and the arm through-holes 44 and the table through-hole 110, so that the movable tab 4 can be maintained at any angular position within the swing range.

[0029] Furthermore, the movable tab 4 is in a semi-ring shape and includes a pair of front and rear separated arm portions 41 and an intermediate connecting arm 43 connected between the pair of the arm portions 41. The pair of the arm portions 41 are respectively rotatably connected to the high platform portion 11. A ring inner vacant area 42 is formed between the pair of the arm portions 41, the intermediate connecting arm 43 and the high platform portion 11; when the movable tab 4 lies down on the low-lying portion 12, when viewed from above, the pair of the arm portions 41 respectively rest on the low-lying portion 12, and a part of the ring inner vacant area 42 extends outside the main body 100. In this way, on the premise that the thickness and the material consumption of the movable tab 4 remain unchanged, more holding spaces can be formed on the movable tab 4 by means of the ring inner vacant area 42. In order to facilitate pulling the main body 100, a pull ring 6 can also be put on the movable tab 4, and the pull ring 6 can be arranged outside the main body 100 by means of the ring inner vacant area 42 extending outside the main body 100, so as to avoid lifting the movable tab 4 upward to protrude from the high platform portion 11. The rotation axis Z of the movable tab 4 is offset to the left side of the wing plate 1. In this way, on the premise that the area of the wing plate 1 remains unchanged, more space can be vacated on the right side of the rotation axis Z for placing the movable tab 4. Therefore, the size of the movable tab 4 in the left-right direction can be correspondingly increased to facilitate being held by hand.

[0030] The second technical solution for limiting the movable tab (the relevant views are omitted and can be understood by referring to Figure 3 and Figure 5 ): It includes a pair of the mounting portions. The pair of the mounting portions are respectively arranged on the front and rear sides of the blocking portion. When viewed from above, the pair of the mounting portions 112 protrude rightward relative to the blocking portion; the movable tab 4 includes an arm portion 41. The arm portion 41 is rotatably connected between the pair of the mounting portions 112 and is located on the right side of the blocking portion.

[0031] As Figures 1-3As shown, when the movable pull tab 4 lies flat on the recessed portion 12, viewed from left to right, the height of the movable pull tab 4 is basically level with the height of the raised platform 11. Here, "basically level" can be understood as the movable pull tab 4 in its flattened state having essentially the same height as the raised platform 11, or the movable pull tab 4 being slightly higher or lower than the raised platform 11, for example, by approximately 0.5mm or 1mm. Visually, the movable pull tab 4 does not protrude significantly from the raised platform 11. Furthermore, when the movable pull tab 4 lies flat on the recessed portion 12, the recessed space above the recessed portion 12 becomes the placement space for the movable pull tab 4. Further, when the movable pull tab 4 lies flat on the recessed portion 12, viewed from left to right, the movable pull tab 4 is essentially obscured by the raised platform 11. The movable pull tab 4 is approximately equal to or smaller than the movable pull tab 4 in the front-to-back direction. According to the above technical solution, this not only helps to cleverly achieve a visually unified and harmonious effect for the wing plate 1, but also helps to reduce the safety hazards of the movable pull tab 4 potentially scratching hands or damaging other objects due to its extension beyond the raised platform 11. Compared to the technical solution of setting a high protrusion on the wing plate 1 like an island-shaped elephant trunk, the wing 1 and the pull tab present a thinner visual effect. Furthermore, the raised platform 11 includes a flat area 111 and an inclined area 110 located to the left of the flat area 111. The wall thickness of the inclined area 110 gradually decreases from right to left, which helps to further optimize the thinner visual effect of the wing 1 and the pull tab.

[0032] The present invention also proposes a zipper 5 (not shown in the figure), comprising a pair of chain straps and a simplified zipper pull suitable for use on the zipper 5, the simplified zipper pull being slidable on the pair of chain straps.
