Description




FIELD OF THE INVENTION




The present invention is directed to lanyard sliders, and more particularly, to an improved system for connecting a slider to a lanyard cord.




BACKGROUND OF THE INVENTION




In sports and other activities, lanyards comprising a cord, are often worn around one's neck in order to retain a small object such as a key, whistle, or identification badge, and yet leaving the hands free. Lanyards have been used in such an application for some time, and are well known. Typically, the ends of the cord are secured together with an easily releasable connection such as a ferrule. Typically a ring, hook, clasp, clip or end fitting hardware is provided for attaching an object to the cord.




Lanyards often include sliders which are used to reduce the size of the loop surrounding the wearer's neck, as well as for aesthetic purposes. Typical sliders are a solid piece of material with one or more holes through which the lanyard may be placed. The lanyard cord is typically threaded through holes of the slider during manufacture of the lanyard due to the fact lanyards are often either fabricated into a loop, or the hardware at each end of the lanyard is too large to pass through the holes in the slider. Lanyard cords are available in many different colors and materials. Lanyards are additionally provided with many different end fittings. Sixty-four combinations are offered in a current catalog and, of course, more could be made. Some customers want a slider and some do not. Carrying assembled lanyards with sliders would double the number of units. It is not practical for a manufacturer to maintain an inventory of all desired assembled lanyards with or without sliders and with cords of varying style, color and end fittings. Special orders could be utilized to reduce inventory needs, but that is also impractical from a cost and time standpoint. Thus, a need exists for an improved system for meeting customer needs.




SUMMARY OF THE INVENTION




In accordance with the invention, a two-piece lanyard slider is provided that can be assembled with a variety of cords and end fittings and with a customer-selected design or logo. One embodiment of a lanyard slider having preferred features and advantages includes a slider comprising a first portion adapted to mate with a second portion having at least one channel to receive a lanyard cord. The slider portions can be readily assembled on a customer selected lanyard cord and end fitting. According to one embodiment, the first portion may comprise a non-circular protrusion that fits within a mating recess in the second portion to restrain the portions from rotation relative to one another. This ensures that a logo or design on the slider is properly oriented. In any of the embodiments, the outer surface of one slider portion has a surface surrounded by a rim for receiving a design or logo.




Another embodiment of a slider for a lanyard comprises a first portion having a split post that fits within a hole in a second portion. Also provided is at least one slot to receive a lanyard cord. In a preferred embodiment, the split post portions include barbs on their tips, and the second portion has a shoulder to retain the barbs.




In one embodiment, the slider first portion has a non-circular protrusion formed on a cap having a disc shape from which the protrusion and a post extend. The protrusion and a recess on the second portion or base are adapted to interact to restrain the slider portions from rotation relative to one another.




According to another embodiment, a slider for a lanyard comprises a first portion having a pair of channels. A slider second portion has two channels that mate with the channels on the first portion to form complete passages for receiving a lanyard cord. The portions are adapted to snap together to capture the cord. The slider may further comprise means to restrict relative rotation between the two portions. The channels may have a substantially semi-circular shape, a substantially semi-elliptical shape, or a substantially rectangular shape. The channels may be either parallel or non-parallel.




With the described sliders, a quantity of slider caps and slider bases are inventoried, together with a quantity of lanyard cords with the various end fitting hardware. When a customer order is received for a lanyard cord of a particular color or type, with a particular end fitting, and with a slider, the cord is assembled into the channels in the slider base, and the cap is snapped onto the base to capture the cord. A desired logo or design can then be mounted on the slider, preferably on a rimmed surface on the cap.




This system is particularly advantageous when the lanyards without a slider are manufactured and assembled in countries with low labor costs. The slider with customized printing, if desired, can then be added in the customer's country which may have higher labor costs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT





FIG. 1

shows a lanyard


10


having a two-piece slider


12


slidably disposed on a lanyard cord


13


positioned slots


14


within the body of the slider


12


. The slider


12


is preferably disposed on the cord


13


such that a flat surface


16


faces outwards as shown. The terms “top,” “bottom,” “front” and “back” as used herein in reference to various parts of the slider


12


will refer to the orientation shown in

FIG. 1

, as this is the orientation in which the slider will most commonly be worn. The front of the slider


12


preferably comprises a flat surface


16


which may be decorated with a logo, decal, or other design as requested by the customer from the manufacturer or seller. In a typical arrangement, a bead or ferrule


18


or other similar item is frictionally disposed on the lanyard cord below the slider


12


to frictionally retain the ring or other device


20


disposed at the bottom of the lanyard


10


. The slider


12


is preferably made of a suitable molded plastic. The plastic used is preferably sufficiently rigid to allow small features to be substantially resilient when necessary. Metals or other materials may also be used without departing from the spirit of the present invention.




As shown in

FIG. 2

, the slider


12


is preferably substantially cylindrical in shape, however, other three-dimensional shapes may be employed. A slider


12


having preferred features and advantages comprises a male portion or cap


22


and a female portion base


24


. Preferably, the cap and base are molded as completely separate elements. The cap


22


comprises features adapted for insertion through a hole


26


in the base


24


. In this embodiment, a post


28


is designed to be inserted in to the hole


26


, such that the cup


22


will “snap-fit” into the base


24


so as not to be readily removable. The caps


22


also preferably has an irregularly shaped protrusion


30


(seen in

FIGS. 3-5

) at the base of the post


28


. The protrusion


30


is adapted to be received by a similarly shaped recess


34


in the base


24


such that the protrusion


30


and recess


34


act as a key in order to restrict relative rotation between the two parts


22


,


24


. Alternatively, as will be recognized by those skilled in the art, the protrusion may be on the base


24


with a corresponding recess on the cap


22


if so desired.




With continued reference to

FIG. 2

, the base


24


also preferably comprises slots


14


shaped and sized to receive a lanyard cord


13


. The cap


22


is preferably sized and shaped such that the cord will be retained within the slots


14


of the base


24


once the slider


12


is assembled, as shown in FIG.


1


. The preferred shape and features of the slots will be discussed below, but the slots may comprise any shape, size or number such that the slider operates as described herein.




With reference now to

FIGS. 2-4

, the male portion


22


generally comprises a substantially flat disc section


38


having on its back side


40


the post


28


extending substantially away from the disc section


38


. The post


28


is preferably divided into two split post portions


42


having barbs


44


at their tips. Alternatively, the post


28


may be split into three or more split post portions as desired. The split post portions


42


are preferably substantially resilient such that they will preferably flex towards one another in the direction of the arrows


46


when the post


28


is inserted into the hole


26


. The split post portions


42


are preferably completely separated such that the gap


48


between them extends along their entire length so as to allow the maximum degree of deflection. Alternatively, the male portion may comprise a single solid post, and the female portion may comprise flexible members within the central hole adapted to receive and retain the post.




The barbs


44


at the distal end of the split post portions


42


are preferably sized and positioned such that the linear dimension indicated by reference number


50


of the split post portions


44


is substantially equal to the linear dimension indicated by reference number


52


on the female portion


24


such that the male and female portions may be assembled substantially as shown in FIG.


4


. The barbs


44


also preferably comprise sloped sections


54


in order to facilitate insertion into the female portion


24


. The hole


26


in the female portion


24


through which the post


28


is to be inserted preferably widens to form a shoulder


56


within the body of the female portion


24


. The shoulder


56


will engage the barbs


44


once the post


28


is fully inserted through the hole


26


, thereby retaining the male portion


22


within the female portion


24


.




With continued reference to

FIGS. 2-4

, the male portion


22


preferably has a rim


58


surrounding the periphery of the front surface


16


of the disc portion


38


. The front surface


16


of the male portion


22


is preferably the visible surface of the slider


12


once assembled on a lanyard cord, as shown in FIG.


1


. Thus the rim


58


surrounding the visible face of the male portion


22


may frame a decal or sticker placed on the flat front surface


16


.




As shown in

FIG. 5

, the protrusion


30


on the male portion preferably comprises a substantially D-shaped (that is, round with a flat edge


60


) raised protrusion


30


at the base of the post


28


. The gap


48


between the two split post portions


42


may extend at least partially into the protrusion


30


. As shown in

FIG. 6

, the female portion


24


preferably comprises a similarly shaped recessed feature


34


in which the D-shaped protrusion will sit when the slider


12


is assembled. The D-shaped protrusion


30


and the D-shaped recess


34


interact to prevent relative rotation which otherwise could result in loss of orientation of the male portion


22


. The protrusion and recess may comprise essentially any non-circular shape such that the male and female portions are restricted in their relative rotations.




In an alternative embodiment shown in

FIG. 7

, the protrusion on the male portion may include one or more pins


62


, and the female portion


24


may have corresponding holes


64


into which the pins


62


may sit once the slider


12


is assembled. In this way relative rotation between the two parts may also be restricted.




The hole


26


through which the male portion may be inserted (see

FIG. 2

) is preferably located at the geometric center of the female portion


24


as viewed in FIG.


6


. On either side of the recess


34


is the pair of slots


14


which provide a space in which a lanyard cord may be placed. The slots


14


have a substantially rectangular cross section, as best seen in

FIGS. 2

,


6


and


7


. The rectangular slots are particularly suited for use with a flat-woven lanyard like that shown in FIG.


2


. Alternatively, other slot cross sections may be desirable to correspond with the shape of the particular lanyard cord to be used. For instance, the slots could be substantially semi-circular or semi-elliptical to accommodate a round or elliptical lanyard cord. The slots


14


are preferably non-parallel as shown in

FIG. 6

in order to conform to a natural position of the lanyard cord (see

FIG. 1

) with the cord


10


being close together at the bottom


66


of the slider, and further apart at the top


68


. The slots


14


may be more or less parallel than those shown as desired. Alternatively, one may desire only a single slot through which both lanyard segments may be placed.




In assembly of the slider


12


, the lanyard cord


13


is placed within the slots


14


formed in the female portion


24


. The post


28


of the male portion


22


is then inserted into the central hole


26


in the female portion


24


while aligning the D-shaped protrusion


30


with the D-shaped recess


34


, until the barbs


44


of the post


28


are fully inserted through the hole


26


. Once fully inserted, the split post portions


42


are returned to their separated position such that the barbs


44


engage the shoulder


56


(see

FIG. 4

) of the female portion


24


, thereby retaining the male portion


22


within the female portion


24


. Once fully assembled, the lanyard


10


will preferably slide freely through the slots


14


, and the disc section


38


of the male portion will prevent the lanyard cord


10


from being removed from the slider


12


.




In an alternative embodiment shown in

FIG. 8

, both the male and female portions


70


,


72


may comprise substantially semi-circular slots


74


sized to receive a lanyard cord with a circular cross section. As with the above embodiments, the male portion


70


comprises a split post


28


with barbs


44


formed to be received within a central hole


26


having a shoulder (as discussed with reference to

FIGS. 3 & 4

) formed in the female portion


24


. The slider of the present embodiment may comprise a protrusion/recess combination to restrain the male and female portions


70


,


72


respectively from rotation relative to one another as discussed above. Alternatively, the embodiment of

FIG. 8

may omit the protrusion and recess combination, thus relying on the lanyard cord within the slots


74


to restrain the male and female portions


70


,


72


respectively from relative rotation. The split post is preferably sized such that the barbs


44


engage the shoulder when the flat surfaces


76


,


78


respectively of the male and female portions


70


,


72


respectively, are in contact. If desired, the slots


74


may be sized such that the lanyard cord is slightly compressed within the slots when the slider


12


is assembled.
