Description

The present invention relates to a slide fastener generally referred to as a zipper, and more particularly to a metal integrated slider and pull tab for the slide fastener.

Zipper, zip, fly or zip fasteners, formerly known as clasp lockers or slide fasteners, are commonly used to join the edges of openings in fabrics or other soft materials such as clothing or bags. It is a device. The slide fastener is used in clothing (jackets, jeans, etc.), luggage or other bags, sporting goods, camping equipment, or other products.

The majority of zippers / zips consist of two rows of protruding teeth made by connecting and meshing rows carrying dozens to hundreds of specially shaped metal or plastic teeth. These teeth may be individual coils or continuous coils and are also referred to as elements. The slider is operated by hand and moves along the row of teeth. Inside the slider is a Y-shaped channel that engages or separates opposing rows of teeth from each other, depending on the direction of movement of the slider.

In general, the zipper represents a small portion of the total cost of the product. However, if it fails, the entire garment or device may become unusable until the zipper is replaced or repaired. The problem is often in the slider part of the zipper. The slider typically consists of a slide portion and a pull tab. The user grabs a pull tab rotatably connected to the slide and pushes or pulls the slide in one or the other direction to move the slide. The movement of the slide causes the teeth to engage or separate from each other when the movement occurs. The slide is typically manufactured to include one or more parts to which the pull tab is attached later. The attachment of the pull tab to the slide is usually achieved by bending the bridge portion of the slide, which is a die cast with a gap for creating an interlocked engagement between the two components. Other methods require the attachment of additional bridge components, which may be bent, tied, or otherwise secured to a slide. However, these structures are weak, easily damaged by repeated use, and the pull tab separates from the slide.

So far, it has been proposed to form a slide and a pull tab with a single operation. However, the proposed methods, devices and the resulting zipper products, when manufactured from metal, cannot be manufactured or are not accepted by industry. Manufacturing a metal slider assembly with a pull tab connected to a bridge has proven extremely difficult due to the rigidity of the metal. The nature of the metal makes it very difficult to retract the tool from around the formed portion without deforming the shape of the formed portion in an undesired manner.

For example, US Pat. No. 2,736,062 (Scheuermann) et al. Disclose a method of molding a slide and a pull together in a single operation. Scheuermann uses four slides that intersect each other at an angle of 45 degrees. The slide intersects at the bridge and pull tab portion of the slider assembly, and the pull tabs are arranged at right angles to the top surface of the slide. However, this method requires that the inner surface of the loop and bridge of the puller include 45 degrees or a similar angle to form a sharp point along the inner surface, as shown in the drawings. The sharp spots make the portion a stress concentration area, and the sharp spots wear very quickly and the surface coating wears out. As a result, the slide assembly discolors and often corrodes the part during the cleaning cycle. In addition, the modified shape significantly limits the movement of the puller in the bridge by reducing the space in which the puller must rotate and slide in the bridge.

US Pat. No. 5,604,962 (Mayerhofer), US Pat. No. 5,698,243 (Wakabayashi), US Pat. No. 4,210,196 (Weiner), and UK Pat. No. 2,220, All of 608 (Liso) show variants of Scheuermann's device. All of these require an angle inside the bridge and pull to retract the tool. The angle is necessary for the tool to work because the tool cannot recede through the hardened metal, even if it is not mentioned in all patents.

US Pat. No. 2,509,278 (Scheuermann) discloses a mold that rotates the pull tab around its vertical axis to eliminate the angle on the inner surface of the pull tab loop. However, the angle of the inner surface of the bridge is still required, and the difficulty in manufacturing the tool with the accuracy required for rotation around the vertical axis of the puller has proven to be too costly. ..

U.S. Pat. No. 4,790,973 (Minami et al.) Discloses another method and device for forming a slider assembly. In Minami, the slide is first molded and when the slide solidifies, the core is partially retracted to form a pull in the second molding operation while the slide is still in the mold.

U.S. Pat. No. 5,013,551 (Akashi) discloses other methods and devices for forming zipper slides from metal. Akashi, like Minami, forms a slide portion in the first operation and a pull tab in the second operation. However, Akashi's pull tabs include pins that engage the bridge of the slide instead of the loops disclosed in other prior art.

U.S. Pat. No. 4,985,969 (Terada et al.) Discloses yet another method and device for forming a zipper slide assembly. Terada is formed in the mold as a second operation and combines an intermediate pull portion having two portions connected to the pin member to form a pull.

U.S. Pat. No. 4,985,969 (YKK Corp.) discloses a lock slider assembly. YKK's lock slider allows the pull tab to be formed in another mold, and the pull tab is placed in the second mold, and the slide is formed around the pin portion of the pull tab to complete the assembly. It is disclosed.

Therefore, there is a demand in the art for devices and methods of forming slides in combination with pull tabs, which slides and pull tabs include a plurality of angled surfaces inside the bridge and loop portion of the pull tab. It can be formed from metal without the need for modified shapes of the assembly. Also, in the art, it operates to allow a greater degree of left-right movement between the slide and the pull tab when operated in the first direction, and in the second direction. There is a demand for slides and pulls that better fit the user's ergonomics and make the slide fasteners a better operation by operating to allow left and right movements to a more restricted degree.

The combined slide and pull assembly should meet the ergonomic needs that the zipper slide assembly must meet in order to achieve acceptance from the end user. This involves providing a slide bridge that includes an inner surface shape that allows free movement and rotation of the pull tab. Also, the zipper slide assembly should not require excessive strength to operate or should contain component components that are too large. In addition, the zipper slide assembly must be assembled together in a manner that does not impair the aesthetic appearance of the finished zipper assembly or garment assembly. The slide assembly adapts to the left-right movement of the puller during closure of the slide assembly and limits the left-right movement during opening of the slide assembly to make the operation smoother and operate the slide assembly. The ergonomics between should be improved.

Accordingly, the present invention provides a die-cast zipper slide assembly formed by a single operation. The assembly overcomes the disadvantages of prior art zipper slide assemblies formed by one or more operations. The zipper slide assembly of the present invention not only provides relatively easy manufacturing, but also slides and slides without the need for movement restrictions on the inner surfaces of bridges and pull loops and without the need for faulty angles. Allows the pull tabs to be manufactured together. The invention also provides a manufacturing method that utilizes at least one sideshift slide, thereby eliminating the need for slides that need to be connected at an angle and the part shape to be modified to accommodate the slide angle. do.

Briefly, the present invention includes a method for manufacturing a slider assembly and a zipper slide assembly for a zipper. The slider assembly is formed by a single die casting operation including the simultaneous formation of a slider and a pull tab. At least one side shift slide is built into the mold, allowing the bridge and pull loop to have perfect geometry and be formed without the centralized flat surface required by prior art. To. The slide assembly includes a puller that includes a structure that allows left and right movement during the closing operation of the zipper teeth and limits left and right movement during the opening of the zipper teeth, depending on the user's ergonomics. It fits well and guides the applied force better for smooth operation of the slide assembly on the tooth.

This embodiment may be used for a zipper chain in which the first zipper chain is the same as or different from the second zipper chain. This embodiment is applied to a waterproof zipper chain or the like, one zipper chain providing fastening and a second zipper chain providing waterproofing.

Referring to FIGS. 1 and 10-14, an alternative embodiment of the slide assembly for a zipper is shown. The slide assembly includes a slide member (12), which is configured and arranged to open and close a zipper chain (not shown). The zipper chain may be of any type known in the art, including coils or individual link members. The slide member (12) includes a top surface (24), the top surface of which is a bridge (16) having a first end (18) and a second end (20) both integrally formed with the top surface (24). ), And the inner surface (26) of the bridge extends laterally across the bridge (16). The first end (18) of the bridge (16) has a first cross-sectional shape (82) and the second end (20) has a second cross-sectional shape (84) and a second. The area of the cross-sectional shape is smaller than the area of the first cross-sectional shape. The pull member (14) includes a loop portion (38) and a first tab portion (40). The loop portion (38) is formed as a continuous loop around the bridge (16) and is integrally formed with the first tab portion (40). The loop portion has a first left-right angle (94) (see FIG. 10) of the puller member (14) when the puller member (14) cooperates with the first end portion (18) of the bridge. Thus, when the pull member (14) cooperates with the second end (20) of the bridge, the bridge cross section (12B) has a second left-right angle (96) of the pull (see FIG. 11). ) (12C).

The loop portion (38) of the pull member (14) includes a pull bar (86) and a pair of arms (88) extending between the tab portion (40) and the pull bar (86). The pull bar (86) includes a pull bar thickness (90) and a pull bar width (92) (see FIG. 13). In at least one embodiment, the thickness and width of the pull bar are the same or substantially the same. By "substantial" is meant within the manufacturing tolerances for the purposes of this application. However, in a preferred embodiment, the pull bar thickness (90) is larger than the pull bar width (92). This configuration offers several advantages over the prior art. The configuration better directs the force to open and close the slide fastener or zipper more smoothly by controlling the possible movement of the pull member (14) with respect to the slide member (12). The configuration also provides the user with comfortable ergonomics by changing the left-right angle of the pull tab with respect to the position of the pull tab member (14) with respect to the slide member (12). If the slide fastener is freely openable and closable, the pull tab (14) can be located in the center of the bridge (16) or at the first end where the maximum left-right angle of the pull tab is obtained. Allowing the user maximum freedom in applying force in an arc or angle while moving the pull tab to the second end of the bridge limits the movement of the pull tab and aligns the force with the slide fastener. Orient well. This configuration provides the user with a comfortable product and automatically directs the force to what is needed to operate the slide fastener, based on the force directly required to open and close the slide fastener. Adjusting the clearance with the bottom surface of the bridge (16) by controlling the thickness of the pull bar (86) provides a structure that allows the movement of the pull member with respect to the slide member to be controlled. The pull bar (86) may have a thickness (90) substantially equal to the distance between the top surface (24) of the slide (12) and the inner surface (26) of the bridge (16). Alternatively, the thickness may be 75% of the distance between the top surface (24) of the slide (12) and the inner surface (26) of the bridge (16). Further, the pull bar (86) includes a width (92). The width (92) of the pull bar (86) may be 25% or more thinner than the thickness. This configuration allows the pull member (14) to move slightly left and right according to the rotation angle of the pull member with respect to the slide member (12). In this embodiment, the left and right movements are restricted so that the pull member (14) is laid parallel to the upper surface of the slide member (12), whereby the user can move it with respect to the slide member (12). Greater force is directed in the direction you want to move. This configuration can be adopted regardless of the overall shape of the loop portion (38). Therefore, the shape of the loop portion (38) should not be limited, but may be polygonal, circular or elliptical.

The slide assembly (10) for a zipper may further include a connecting link (54) formed so as to be disposed between the pull member (14) and the slide member (12). The connecting link (54) is preferably formed as a continuous, seamless member that extends around the bridge (16) and the connecting link loop portion (38) to attach the bridge (16) to the pull member (14). Connecting. In a preferred embodiment, the connecting link (54) is configured in the same manner as the pull member (14) described above, and the loop portion (38) of the connecting link (54) is the pull bar (86) and the pull member (14). Includes a pair of arms (88) extending between the pull bar (86) and the pull bar (86). The pull bar (86) includes a pull bar thickness (90) and a pull bar width (92), and the pull bar thickness (90) and pull bar width (92) are of the connecting link (54) as described above. Can be modified to control movement.

With reference to FIGS. 1-14, the pull tab or slide may include, but is not limited to, a sign (78) in the form of a logo, graphic, text, etc., which is integrated as part of the slide assembly (10). Note that it may be formed in. It may also include, but is not limited to, serial numbers, lot numbers, part numbers, patent numbers, trademarks, and the like. This embodiment is specifically used in the die casting process to form slide assemblies from metals and thus various metals such as, but not limited to, zinc, aluminum, magnesium, titanium, copper, brass and suitable thereof.
