The International Patent Classification protocols designated classes A44B 19/24 & 19/26 for zipper pulls zipper and fastener sliders.
U.S. Patent Application 20020069494, McCrum published Jun. 23, 2002 describes a three element zipper pull structure that includes a U-shaped wire bail having ‘hook’ ends extending perpendicularly outward or inward from the legs of the U-shaped wire bail sandwiched between two handle halves that have cavities milled or molded into the joining faces that provide receptacle passageways for accommodating the extending legs, and capturing the outward or inward extending ‘hook’ ends of the U-shaped wire bail.
U.S. Pat. No. 7,574,783, Muratsubaki et al, issued Aug. 18, 2009, describes a zipper pull structure for a zipper and fastener slider that is inserted into a flexible cover where the cover has a cavity with a configured mating or receiving surface with lugs and recesses, and the tab structure has an insert section with a complimentary configured surface with lugs, holes and/or recesses, that fits snugly in and seats in the configured cavity of the cover when fully inserted into cavity of the cover. The zipper pull structure includes a integral loop opposite the insertion end for coupling to loop tang of the slider
U.S. Pat. No. 4,368,562, Minami, issued Jan. 18, 1983, describes an ornamental zipper pull for a zipper and fastener slider that includes a zipper pull with a lateral projection at its tip, and a resilient body with a longitudinal, slotted cavity having a channel with a wider locking port opening at its distal end for receiving the lateral projection of the zipper pull. The overhanging cavity walls on either side of the slot channel function as cantilevered resilient flaps that displaces outward as the tip of the zipper pull is inserted into the slot cavity and snap inward when the lateral projection at the tip registers with the wider locking port for locking the resilient body onto the zipper pull.
SUMMARY OF THE INVENTIONAn easily fabricated replacement zipper pull for zippers and slide fasteners suitable for mounting and safely displaying cabochons and jewels are described each having a solid blank body presenting a mounting surface and an open hexahedral slot, drilled, routed, molded and/or cast, penetrating into a side of blank body beneath the display surface having a selected width, height, and depth with a transverse passageway with a length greater than the width of the slot at its base-end, and a height at least equal to the height of the hexahedral slot for providing anchor holes on either side of the slot at its base end for receiving outward, perpendicularly extending distal tips at the end of legs of a U-shaped spring bail sized for insertion into the slot having cord-width at most equal to the width of the hexahedral slot where the perpendicularly extending distal tips of the legs of the U-shaped bail span outward to a width greater than width of the hexahedral slot. The U-shaped spring bail of invented replacement zipper pull is looped through the conventional loop tang projecting upward from a zipper or fastener slider and then is inserted into the hexahedral slot opening penetrating into the blank body to a point where the outward projecting distal tips of the U-shaped bail legs register with, and snap into the anchor holes on the opposite sides of the hexahedral slot at the bottom of the slot.
The blank body with a cabochon or jewel mounted on the display surface serves as a grip for sliding the zipper or fastener slider to open or close a garment or other enclosure, e.g., a purse, satchel, briefcase and the like.
The primary and novel advantages of the invented replacement zipper pull relate to simplicity of manufacture. In particular, the manufacturing steps required are:
-
- a) forming a U-shaped spring bail from a stiff wire material having small diameter (dS), and a Young's Modulus of Elasticity (E) ranging between 23 and 30, and having legs extending in a common plane of a specified length (LS), with an outside cord-width (WS) and with distal tips extending perpendicularly outward spanning to a greater width (WT) in the common plane;
- b) forming a solid blank of a chosen material in a desired configuration establishing a center of mass, and presenting a display face and having an open hexahedral slot symmetrically penetrating into the body with a width (WM) oriented parallel to the display face, with a height, (HM) and with a base at a depth (DM) near the center of mass of the blank body; and
- c) creating an interior passageway equal to the height (HM) of the hexahedral slot within the blank body having a length (LP) greater than the width (WM) of the slot transversely across the base of the slot for providing anchor holes to receive the outward extending distal tips of the legs of the U-shaped spring bail, where:
(WS≦Wm<WT≦LP), (dS≦HM) and (DM<<LS).
If appropriate, the U-shaped spring bails may also be stress relieved in an oven to remove accumulated bending stresses after they are formed for increasing functionality and durability of its elastic or ‘spring’ properties, particularly under circumstances where it is anticipated the zipper pull may be frequently detached and reattached to multiple different blank bodies and/or zipper and/or fastener sliders.
In fact, an advantageous feature of the invented replacement zipper pull relates to the removability of the zipper pull after it is attached to a zipper or fastener slider. In particular, selecting a ratio of the length of the extending U-shaped spring bail legs (LS) to the depth (DM) of the receiving hexahedral slot in the blank body determines the distance between the curved ‘U’ cord-section of the a spring bail above the surface of the blank body, hence the torque required to, and the ability to functionally squeeze the legs of the bail together in order to disengage the outward perpendicularly extending tips of the bail from the holes on opposite sides of the hexahedral slot. In particular, the shorter the bail leg length above the surface of the blank body, the greater the torque required for, removing the U-shaped spring bail anchored within the hexahedral slot of the blank.
Other advantages of the invented replacement zipper pull relate to the ability to closely fit the dimensions of the hexahedral slot in blank to those of the U-shaped spring bail and visa-versa, thus minimizing, if not eliminating the possibility of inadvertent disengagement of the spring bail from the blank. Also the close fit of the hexahedral slot and the U-shaped spring bail orients and limits the degrees of allowed rotation of the display surface of the blank with a mounted cabochon or jewel secured by the bail hanging from the loop tang of a zipper or fastener slider.
