Many hobbyists have taken up beading as a past time, making decorative jewelry and ornamental objects for their families and friends as well as themselves. Many beaded items are formed by placing beads on a wire or other filament to make necklaces, bracelets, key rings, bangles and other decorative items. Because many beaders like to practice their hobby in odd moments of spare time as they go about their daily life, transportability and convenience are important in the accessories that they use. One issue involves beading wire which is often sold on a spool which, due to its inherent stiffness, allows the wire to spontaneously unspool when carried about in a purse or beading, often putting crimps in the wire making it either unattractive for many of the beaded projects or difficult to use or too often spoiling it completely for beading applications. Beading wire is of a rather specialized construction, normally comprising a multiplicity of strands, most often, 7, 19, 21 or 49, so that it will drape properly once the beads are strung upon it. Because this drapability makes it quite easy for beading wire to come spontaneously off of a reel or unspool, a rather specialized dispenser is required.
This invention relates to a dispenser for beading wire or other beading filaments which may be transported easily and conveniently which does not allow the wire to unspool spontaneously but makes it easy for the beader to withdraw the desired amount while ensuring that the beading wire even though protected does not retract into the dispenser overly easily as well as ensuring that, if by happenstance it is urged inwardly into the dispenser, the beader will have little difficulty restarting it as the dispenser is easily openable.
The invention is described in detail below with reference to the various Figures, wherein:
The invention is described in detail below with reference to several embodiments. Such discussion is for purposes of illustration only. Modifications to examples within the spirit and scope of the present invention, set forth in the appended claims, will be readily apparent to one of skill in the art. Terminology used throughout the specification and claims herein is given its ordinary meaning.
In the embodiment shown in
Retention flap 66 having retention slot 68 formed therein adjoins housing half 22 along second living hinge 70. Retention lug 72 projecting from housing half 24 has prismatic base 74 adjoining housing half 24 while bulbous end portion 76 is spaced distally therefrom. Reel brakes 78 are defined by U-shaped slots 79 formed into generally circular planar portions 32 and 34 forming a tongue shaped flap 80 bearing against inwardly projecting retarding projections 82 which frictionally engage flanges 44 and 46. Retarding projections 82 of reel brakes 78 project upwardly from generally circular planar portion 32 of housing half 22 and bear against flanges 44 and 46 of reel 42 to prevent free-wheeling thereof but are free to retract slightly as each of retarding ridges 84 engage retarding projections 82 seriatim as reel 42 rotates with dispenser 20 while wire W is withdrawn therefrom. When housing halves 22 and 24 are urged against each other and peripheral walls 36 and 38 are overlappingly engaged as described above, dispenser 20 may be locked into the closed configuration with retention lug 72 passing through retention slot 68 in retention flap 66 as shown in

Preferably, a polymeric beading wire guide is provided having an axis about which the reel is rotable and an integrally formed polymeric arm 310 extending from the axis of said hub to a location exterior to said flanges, wherein the reel braking force and the beading wire restraining force are exerted by the arm.
In a preferred embodiment of the method of manually dispensing beading wire by a user, the method comprises the steps of: providing a reel, manually graspable by a user and adapted to be held in the user's palm, having: a hub having an axis of rotation and a pair of spaced apart flanges defining an annular wire storage region between said flanges and exterior to said hub, said reel being rotable around the axis of rotation of said hub; a length of beading wire wrapped around said hub, and disposed between said flanges; wherein when the reel is held in the user's palm, the beading wire is being manually withdrawn by said user and a grip is provided for grasping the beading wire and exerting a beading wire restraining force on the wire to prevent unreeling from around said reel without rotation of said reel around said axis; and a brake is provided for exerting a reel braking force acting upon at least one of the flanges to hinder free rotation of said reel.
Preferably, the reel braking force and the beading wire restraining force are exerted by a polymeric arm 310 extending from the axis of said hub to a location exterior to said flanges. In preferred embodiments, the mass of polymer included in said arm 310 is less than 10 grams; and the arm 310 is integrally formed from polymeric material.
In a more preferred embodiment, the method comprises the steps of: providing a reel having: a hub having an axis of rotation and a pair of spaced apart flanges defining an annular wire storage region between said flanges and exterior to said hub, said reel being rotable around the axis of rotation of said hub; wherein the reel has a length of beading wire wrapped around the hub and disposed between the flanges; and a dispensing arm 310 integrally formed from polymeric material, extends from the hub of said reel to a location exterior to the flanges, the mass of polymer included in the arm 310 being less than 10 grams and the dispensing arm 310 has: a gripper formed therein for grasping the beading wire and exerting a beading wire restraining force on the beading wire to prevent unreeling from around said reel without rotation of the reel around said axis; and a pressing foot for pressing against at least one of the flanges and exerting a reel braking force acting thereupon to hinder free rotation of said reel, and the reel is held, and the beading wire being manually pulled, by said user. Wires usable with the method include beading wire having a plurality of at least 7 strands up to 49 strands and ranging in diameter from between 0.007″ and 0.024″ wherein the number of strands in the beading wire is either 19 or an integral multiple of 7 with the strands being embedded in a cylindrical polymeric matrix, preferably comprising a polyamide such as nylon. More preferably, the beading wire comprises 7, 19, or 21 strands. In the case where the beading wire comprises 21 or 49 strands, the strands are arrayed in circular groups of 7 strands combined to form the finished beading wire.
A particularly desirable feature of the present invention lies in the controlled force required for dispensing wire. Preferably, the force required to withdraw wire from the dispenser varies with the wire diameter in accordance with the following Table 1.
In preferred embodiments, the dispenser will be formed from polypropylene and the transverse distance between the walls of said longitudinal channel is between about 1/32″ and 3/32″ preferably about 1/16″, with the length of the longitudinal channel being between about ½″ to about 1″. Experiments were conducted using a polypropylene dispenser 20 hung from a support 311 with a small tray 312 attached to the end of the wire. Weight was successively added to the tray 311 to determine the weight that the wire was capable of sustaining (retain force) and the weight required to withdraw wire W from the dispenser 20 (extend force) as illustrated in
Accordingly, it can be appreciated that, in a dispenser configured as suggested, only a moderate but easily sustainable force is required to withdraw wire from the dispenser but the wire will not unwind unless some force is applied to the free end. Thus the wire remains neatly in place in the dispenser unless the user wishes to withdraw wire but only a moderate force is required to withdraw as much wire is required.
In a still more preferred embodiment, the method of manually dispensing beading wire by a user, comprises the steps of: providing a reel having: a hub having an axis of rotation and a pair of spaced apart flanges defining an annular wire storage region between said flanges and exterior to said hub, said reel being rotable around the axis of rotation of said hub; a length of beading wire wrapped around said hub and disposed between said flanges, said beading wire having a diameter between 0.007″ and 0.024″ and comprising a multiplicity of at least 19 strands or 7 strands or an integral multiple of seven strands embedded in a polyamide matrix; providing a dispensing arm 310 integrally formed from polymeric material, extending from the hub of said reel to a location exterior to said flanges, the mass of polymer included in said arm 310 being less than 10 grams, said dispensing arm 310 having: a gripper formed therein for grasping said beading wire and exerting a beading wire restraining force on said beading wire to prevent unreeling from around said reel without rotation of said reel around said axis; and a pressing foot for pressing against at least one of said flanges and exerting a reel braking force acting thereupon to hinder free rotation of said reel, said reel being held, and said beading wire being manually pulled, by said user.
In manufacture, dispenser 20 can be formed from any convenient polymer or even metal if it is acceptable to substitute a true hinge for the living hinge; but dispenser 20 will normally be formed from a polymer capable of forming a living hinge of rather extended duration, typically polypropylene or polyethylene although engineering resins like nylons or acetals can be substituted if shorter life span is acceptable. The mechanical dimensions suitable for living hinges are well known.
