Description




BACKGROUND OF THE INVENTION




The present invention relates generally to watchbands, and in particular, to an improved adjustable watchband that provides for removal and insertion of individual links within a watchband without the need of special coupling or decoupling tools.




Generally speaking, the watchband links themselves or the watchband/watchhead casing are connected together by the use bars or springbars, respectively, or other assembly constructions that permit the attachment or detachment of individual links within the watchband, or permit the attachment or detachment of the watchband to the watchhead casing. This enables a wearer to adjust the length of the wristband to accommodate the size of the wearer's wrist, as the length of the desired watchband (i.e. the tightness about one's wrist) will vary from user to user, or from time to time.




Many such attempts to provide for easy coupling and decoupling of links, for watchbands or other devices, are known. For example, U.S. Pat. No. 3,976,233 describes a wristwatch strap and the use of resilient loops in which adjacent link ends may be axially introduced. U.S. Pat. No. 1,939,346 describes the use of a hook a


2


and bar a


3


arrangement for coupling the links, wherein the use of notches a


4


permit the slidability of the bar into corresponding hooks. U.S. Pat. No. 2,699,035 describes yet another example of an ornamental chain for bracelets in which the individual links may be connected or disconnected.




However, the foregoing constructions do not provide the ease with which one may desire to remove individual links while at the same time providing the desired security that the links will not inadvertently become detached.




Accordingly, it is desirable to provide a watchband construction for a wristworn timepiece and/or wrist instrument, such as a watch, that overcomes the above-identified deficiencies and achieves the above and below-identified objectives.




SUMMARY AND OBJECTS OF THE INVENTION




Generally speaking, in accordance with the present invention, a removable link for use in an arrangement comprising a plurality of interlocking links is provided. In a preferred embodiment, the removable link is used in a watchband and preferably comprises a link body having a first end and a second end; a hand portion having a bar receiving region formed at the first end of the body; a retractable retaining pin having a first end within the link body and a second end extending from the link body into the bar receiving region, the retractable retaining pin being slideable within a bore provided in the link body, the retaining pin for retaining a retainable bar in the bar receiving region; a biasing member, coupled to the retaining pin, for biasing the retaining pin towards the bar receiving region; and a retractor, coupled to the retaining pin, for retracting the retaining pin away from the bar receiving region; whereby the retainable bar is retained within the bar receiving region by the retaining pin, and where the retainable bar is decoupled from the removable link by retracting the retaining pin away from the bar receiving region sufficiently to allow the retainable bar to be removed therefrom.




The link body may include integrally formed, spaced apart first and second shoulders which the bar is secured between. The removable link is preferably decoupled from the decoupling link by decoupling the bar of the removable link from a bar retaining region of the decoupling link. The retainable bar may be part of another one of the plurality of interlocking links or may be a springbar coupled between a pair of lugs which themselves are part of a watch casing.




In another preferred embodiment, an arrangement comprising a plurality of interlocking links is provided. Here, the arrangement comprises at least one removable link and at least one decoupling link. The removable link preferably comprises a link body having a first end and a second end; a hand portion having a bar receiving region formed at the first end of the body; a bar coupled to the second end of the body; a retractable retaining pin having a first end within the link body and a second end extending from the link body into the bar receiving region, the retractable retaining pin being slideable within a bore provided in the link body, the retaining pin for retaining a retainable bar in the bar receiving region; a biasing member, coupled to the retaining pin, for biasing the retaining pin towards the bar receiving region; and a retractor, coupled to the retaining pin, for retracting the retaining pin away from the bar receiving region. In a similar manner, the decoupling link comprises a link body having a first end and a second end; a hand portion having a bar receiving region formed at the first end of the body; a retractable retaining pin having a first end within the link body and a second end extending from the link body into the bar receiving region, the retractable retaining pin being slideable within a bore provided in the link body, the retaining pin for retaining the bar of the removable link in its bar receiving region; a biasing member, coupled to the retaining pin, for biasing the retaining pin towards the bar receiving region; and a retractor, coupled to the retaining pin, for retracting the retaining pin away from the bar receiving region. In this construction, the first end of the removable link is decoupled from the arrangement by causing the retainable bar to be decoupled therefrom by retracting the retaining pin thereof away from the bar receiving region sufficiently to allow the retainable bar to be removed therefrom, and further whereby the second end of the removable link is decoupled from the decoupleable link by causing the retracting of the retaining pin of the decoupling link away from the bar receiving region of the decoupling link sufficiently to allow the bar of the removable link to be removed therefrom. This arrangement may include a plurality of removable links and also be part of a watchband, that may also be comprised of other removable links that require a tool for further adjustment, as opposed to the above described removable links, (i.e. no special tool needed for decoupling).




Lastly, a link for releasably coupling a watchhead to a watchstrap is provided. In this embodiment, the link preferably comprises a link body having a first end and a second end, a hand portion having a bar receiving region formed at least at the first end of the body, a retractable retaining pin having a first end within the link body and a second end extending from the link body into the bar receiving region, the retractable retaining pin being slideable within a bore provided in the link body, the retaining pin for retaining a retainable bar in the bar receiving region, a biasing member, coupled to the retaining pin, for biasing the retaining pin towards the bar receiving region; and a retractor, coupled to the retaining pin, for retracting the retaining pin away from the bar receiving region, whereby the second end of the link body may be coupled to an end portion of a watchstrap, and if the retainable bar is a springbar of the watchhead, the link releasably couples the watchstrap to the watchhead or if the second end of the link body is coupled to a springbar of the watchhead and the retainable bar is coupled to an end portion of the watchstrap, the link may also releasably couple the watchstrap to the watchhead.




Accordingly, it is an object of the present invention to provide an improved watchband for a wristwatch that permits easy linking and delinking of individual links within the watchband, all without the need to use a special tool or device therefor.




Another object of the present invention to provide an improved watchband in which the removable link(s) are not visible from the upper surface of the watch (i.e. when on a user's wrist).




Yet another object of the present invention is to provide an improved watchband in which the link configuration conforms to the shape of the existing watchband design.




Still another object of the present invention is to provide an improved watchband in which the removable link(s) have the same function (i.e. movement and integration) as the non-removable links which make up the remaining interlocking links of the watchband.




Yet another object of the present invention is to provide an improved watchband in which the removable link can be removed by hand.




Still another object of the present invention is to provide an improved watchband that can incorporate a plurality of removable links.




Yet another objective of the present invention is to provide an improved interlocking link arrangement that can be utilized for bracelets, necklaces and other devices where adjustability is desired.




In yet another advantage, the present invention can be used so as to interchange various watchheads with the interlocking link arrangement disclosed herein.




Still a further advantage of the present invention is to provide the present invention as an attachment, such as an endpiece, to either the watchhead or the watchstrap, for releasably securing and detaching respective inter-changeable straps or watchheads to each other.




Still other objects and advantages of the invention will in part be obvious and will in part be apparent from the specification.




The invention accordingly comprises the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the invention will be indicated in the claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Reference is first made to

FIG. 1

, which illustrates a plurality of interlocking links, which, in the preferred embodiment, form part of a watchband, generally indicated at


5


, constructed in accordance with the present invention. In particular, illustrated in

FIG. 1

are individual links A, B, C and D. Particular reference hereinafter will be made to link D, it being understood that links A, B and C are all preferably constructed similarly. Link D is preferably comprised of a body, generally indicated at


10


, having integrally formed shoulders


12


,


14


with a bar


16


positioned therebetween. The manner in which bar


16


is fixedly secured within and between shoulders


12


,


14


of link


14


is well known in the art. Each bar


16


permits each respectively adjacently coupled link to rotate thereon in a known manner. For example, link C is rotatably coupled to link D, link B is rotatably coupled to link C, etc.




To achieve this coupling, each link A, B, C and D includes a head


9


with an aperture therethrough, though which each respective bar


16


of one adjacent link is rotatably secured.

FIG. 1

illustrates the underside of links A, B, C and D, although it should be understood that the top side of links A, B, C and D may appear similar and may include additional ornamentation for aesthetic purposes forming no part of the invention, but discussed in further detail below with reference to FIG.


5


. It should be understood that links A-D are preferably constructed not to be removable from watchband


5


.




Reference is now made to

FIG. 2

, which illustrates a plurality of additional interlocking links forming a second portion of watchband


5


. In particular, illustrated in

FIG. 2

are links E, F and G, with particular reference now being made to link F, as it is constructed in accordance with the present invention. Link E is preferably identical to link F. Link G is preferably constructed similarly to link E and F. Hereafter, links E and F shall be coined “removable links” and link G shall be coined a “decoupleable link”.




Link F is preferably comprised of a body, generally indicated at


20


, having a first end and a second end. At the second end are integrally formed shoulders


22


,


24


with a bar


26


positioned therebetween. The manner in which bar


26


is fixedly secured within and between shoulders


22


,


24


is in a similar manner to bar


16


of links A-D of FIG.


1


. At the first end of link F is a hand portion, generally indicated at


30


, which extends from and is preferably integral with body


20


. As should be now understood, hand portion


30


of link F is constructed to receive bar


16


of for example, link D and/or a bar


26


of link E. Any bar


16


or any bar


26


shall be coined the “retainable bar” as it is a bar retainable in the hand region. Also deemed a “retainable bar” is a springbar on a watchhead such as that in U.S. Pat. No. 4,653,933, incorporated by reference as if fully set forth herein. In a similar manner, hand portion


30


of link G is constructed to receive therein bar


26


(i.e. the retainable bar) of link F. For completeness, if a second removable link (i.e. link E) is present, it may instead be coupled to link D in the manner disclosed below.




Reference is now made to

FIG. 3

which illustrates, from a cross-sectional view, the preferred construction of links E, F and G. Hand portion


30


includes a fingerextending member


32


extending from body


20


so as to form a gap, or bar receiving region


34


. Extending into gap


34


is a retractable retaining pin


36


. Pin


36


includes a head


37


which extends into gap


34


and a body


39


which is retained in a bore


38


within body


20


. Pin


36


is slideable within bore


38


and biased towards gap


34


by a spring member


40


. Spring member


40


and pin


36


are inserted through the back of body


20


via a hole formed therein towards the second end thereof. Once pin


36


is inserted into bore


38


, spring


40


is inserted behind pin body


39


. Spring


40


rests flush to the back of pin body


39


, and thus needs no permanent securing thereto, as spring


40


needs only to mate flush to pin body


39


and is kept from moving by the fit within the bore


38


. The second end of spring member


40


is trapped in place by a screw retainer pin, or plug, that can fit into body


20


and retains the spring member within the bore. Such a plug is shown in the aforementioned U.S. application Ser. No. 09/627,459 (Docket AO487A), the disclosure of which is incorporated by reference as if fully set forth herein, although forms no material part of the present invention. It is this configuration, a linear bore drilled from the backside of body


20


that allows assembly of the pin body and spring member within the bore and into the link. After this assembly, bar


26


is then driven in place in a known manner. Inner wall surfaces


42


in bore


38


help prevent retaining pin


36


from sliding out of bore


38


or from overextending into gap


34


. Pin


36


may be compressed inwardly deeper within bore


38


against the biasing of spring member


40


as described below.




A retractor


44


is provided and coupled to retaining pin


36


for retracting retaining pin


36


away from the gap


34


(in the direction of arrow “y”) and deeper within bore


38


. In the preferred embodiment, retractor


44


is a one-piece member including a head


46


and a stem


48


. Stem


48


of retractor


44


may be secured within pin body


39


by a press fit. However it should be understood that this could be accompanied by glue, loctite, etc., for additional security, and/or even tapping the hole in the pin body. A channel is formed in body


20


having sidewalls


50


and


52


to prevent overcompression of spring


40


and retractor head


46


or stem


48


, respectively, within body


20


. As seen in

FIG. 3

, the top surface of head


46


extends above the top surface of body


20


so as to permit a user (such as by using a thumb or index finger or fingernail thereof) to engage retractor


44


and retract it in the direction away from gap


34


(in direction “y”). In this way, pin


36


is biased away from and out of gap


34


as well. However it is also contemplated that a small hole, slot, grooves and/or recess can be added to the top of retractor


44


to allow common items, such as a pen tip, paper clip, coin, screwdriver, etc., to be inserted into the hole, slot, etc. to aid in the ease of activating retractor


44


.




In operation, link E or link D (if link E is omitted) or a springbar of a watchhead is releasably secured to link F by sliding bar


26


(i.e. “the retainable bar”) downwardly (in the direction of arrow “x”) into gap


34


while retractor


44


is biased in the direction of arrow “y” causing pin


36


to be compressed inwardly thereby retracting head


37


of pin


36


out of gap


34


. After pin


26


of link E (or pin


16


of link D if link E is absent from consideration) passes below pin


36


in gap


34


, retractor


44


may be released thereby causing pin


36


of link F to once again be biased outwardly out of bore


38


towards and into gap


34


. In this way, the retainable bar


26


of link E (bar


16


of link D) is retained within gap (bar retaining region)


34


by retaining pin


36


of link F. Retainable bar


26


of link E (bar


16


of link D or springbar of a watchband) is decoupled from removable link F by causing retractor


44


once again to be biased by the user in the direction “y”, causing retaining pin


36


to be moved sufficiently out of gap


34


to allow retainable bar


26


/


16


to be removed from gap


34


in a direction opposite direction “x”. In this way, bar


26


of link E is securely, and releasably retained within gap


34


of link F.




In the figures and as stated above, in the preferred embodiment, link G is coined the “decouplable link” because, in the most simple of interlocking link arrangements, link F is entirely removable from watchband


5


while link G is preferably coupled to a non-removable link or a link needing a special tool for removal. For example, bar


26


of link G may be coupled to a link constructed similarly to link C. However, bar


26


of link F must also be releasable from bar retaining region


34


of link G. For this reason, link G includes a hand region, spring member, retaining pin and retractor preferably identical to link F. With link E absent, only one removable link (i.e. “F”) is shown in

FIG. 2

although the arrangement contemplates more being utilized such as in FIG.


5


.




Reference is very briefly made to

FIG. 4

which illustrates a removable link


100


, the subject of which is disclosed and claimed in the aforementioned U.S. application Ser. No. 09/627,459 (Docket AO487A). That is, retractor


44


may be eliminated and the appreciation of a more rounded head


37


permits the direct biasing of pin


36


within bore


38


. In this construction, force upon pin


36


within and out of gap


34


includes a horizontal component in the “y” direction (and that opposite to the “y” direction) will cause pin


36


to retract within bore


38


in the manner described above, and upon the passing of a bar below or above pin


36


, pin


36


will again spring forward into gap


34


by way of the spring member


40


contained within bore


38


of link


100


thus retaining a bar therein. To achieve the forgoing, bar


16


of a link, such as link D (or a springbar of a watchhead) is preferably slidably forced passed the rounded end of head


37


of pin


36


of link


100


. Pin


36


is compressed inwardly (in the direction of arrow “y”) as bar


16


of link D passes thereby, but is once again biased outwardly into gap


34


once bar


16


has cleared head


37


of pin


36


. In this way, bar


16


of link D is securely and yet releasably retained within gap


34


of link


100


.




To insert (or decouple) a link into (or from) link


100


, the links may be rotated perpendicular relative to each other. By then lightly forcing the links together, pin le will compress so as to allow bar


16


to pass thereby. Upon the clearing of bar


16


passed pin


36


, pin


36


will securely retain bar


16


within gap


34


. To decouple the links, they may be, but not necessarily, perpendicularly aligned and then rotated clockwise or counterclockwise as illustrated in the aforementioned copending application, thus causing the decoupling of the links, as the pulling action of the links away from each other in the manner described therein causes bar


16


of link D to move out of gap


34


of link


100


, first contacting the end of pin


36


and thereby compressing pin


36


so as to allow bar


16


to pass thereby. Upon the clearing of bar


16


relative to pin


36


, link D, and all links still coupled thereto, are hence decoupled from link


100


. Of course, the links may be decoupled without providing any perpendicular or clockwise/counterclockwise rotation. That is, merely pulling link D out of gap


34


in a direction of arrow “z” would also work.




To summarize the foregoing, reference is now made to

FIG. 5

which is a top plan view of watchband


5


more completely assembled and highlighting the aforementioned aspects and features of the present invention. Specifically, watchband


5


is comprised of a plurality of links, not all of which are removable. In particular, not every link need be removable. Such a construction will reduce the manufacturing cost, and is most practical in that no more than a few links ever need to be removed at one time, although a wristband in which every link is removable is within the scope of the invention.




As shown in

FIG. 5

, links C, D, E, F, and G (and those links respectively identical thereto) are specifically highlighted, as it is shown that it is preferable to have an equal number of removable links on either side of a clasp


90


, since for symmetry, it may be desirable to remove an equal number of links on each side of the clasp


90


. In the disclosed example, a metal foldover buckle (clasp)


90


is used. A wristband using this type of clasp can easily take advantage of the present invention. Removing only one removable link at a time is easily contemplated hereby.

FIG. 5

illustrates how, from the top plan view, it is at least difficult to determine which links are removable. Multiple removable links on either side of clasp


90


is preferred to provide maximum flexibility to a user.




Still further, while the present invention is disclosed most preferably with regard to watchbands, the present invention could also be use for bracelets, necklaces or any other device that could appreciate the adjustability of the interlocking link arrangement of the present invention.




Lastly,

FIGS. 6A-D

illustrates another removable link


69


, constructed in accordance with yet another embodiment of the present invention. Removable link


69


may comprise a body


70


having shoulders


72


,


74


with a bar


76


therebetween in a manner similar to links A-G. A hand portion


77


similar to hand portion


30


is provided at one end of body


70


. A channel


78


is provided in body


70


. Link


69


also includes a slidable cover, generally indicated at


80


, having a head


82


and body


84


. Body


84


is biased in channel


78


in such a manner that one end


81


of head


82


is positionable over a gap


86


formed in hand portion


77


. Cover


80


can be biased by way of a spring member (not shown) so as to cover gap


86


or be removed from overlaying gap


86


. In this way, when end


81


is covering gap


86


, a retainable bar is securely retained within gap


86


and when it is desired to have the retainable bar (such as from link D or a springbar) removed therefrom, biasing cover


80


away from over gap


86


with a finger or nail thereof will allow the removal of the retainable pin in a manner similar to above. That is, link


69


is actuated by sliding cover


80


rearward along a central shaft (not shown) which compresses the spring. Once in this position link


69


can be simply removed from an adjacent link as the retainable bar is no longer trapped by cover


80


. Cover


80


may also include several thin ribs


83


and/or a narrow finger slot


85


on the top surface thereof to facilitate gripping and sliding of the cover rearward. The link mechanism could be housed as a unit, which then would drop into “shell” links to make a modular construction. This would allow for the use of a combination of materials. Also, the shape of the link or cover


80


may have a flange or protrusion which could facilitate in the sliding of cover


80


rearward, thus acting as a “key”. An actual “key-type” element may also be included with the invention, or even incorporated into the buckle or strap, to readily aid a user in sliding the cover rearwardly. Link


69


could be used in place of links E or F in

FIG. 5

with no loss of functional superiority to the prior art.




While the invention has been particularly shown and described with respect to preferred embodiments thereof, it will be understood by those skilled in the art that changes in form and details may be made therein without departing from the scope and spirit of the invention.




For example, the material of the links is one of design choice and may be comprised of metal, steel, plastic, combinations or forms thereof, and may include brass, stainless steel, alloys, titanium, aluminum, composites, or the like. The spring may be made of varying materials, such as metal, PVC, Silicone, Rubber, etc., formed into a cylindrical shape (or other shape that would be accommodated in the bore, so as to allow more flexibility in the shape of the link) and inserted into the bore as any compressible material trapped in the bore can act as a spring due to the nature of the material.




Also, as end pieces to a watchstrap (such as a leather watchstrap for example) or as attachments to the watchhead (such as to the respective springbars thereof), the present invention provides for added enjoyment as interchangeable watchstraps or watchheads can be used by merely “linking” up each other as disclosed herein. That is, the present invention need not be used with a decouplable link since it would be used more as a clip than a removable link. That is, the link could be incorporated at the ends of a strap, such as a leather strap whose end is wrapped and secured (by stitching for example) around the bar of the link as would be understood in the art, and then just clipped onto the watchhead, such as the springbars thereof. Likewise, the link may depend from the watchhead (from the springbar, for example, or molded to the watchhead) and clipped on to the ends of a watchstrap (i.e. the watchstrap would have the retainable bar secured thereto, such as by stitching or other known method). In this way, an economical and easy way to provide for interchangeable straps and/or watchheads is provided. It is therefore also possible to construct the present invention so as to have the aforementioned hand portion at each end of the link for securing the watchhead to the watchstrap. The embodiment of

FIG. 4

may also be used in the manner set forth herein.

A watchband, the watchband comprising:a plurality of interlocking links, wherein at least one of the interlocking links is a removable link and at least one of the interlocking links is a decoupling link; wherein the at least one removable link comprises: a link body having a first end and a second end; a hand portion having a bar receiving region formed at the first end of the body; a bar coupled to the second end of the body; a retractable retaining pin having a first end within the link body and a second end extending from the link body into the bar receiving region, the retractable retaining pin being slideable within a bore provided in the link body, the retaining pin for retaining a retainable bar in the bar receiving region; a biasing member, coupled to the retaining pin, for biasing the retaining pin towards the bar receiving region; and a retractor, coupled to the retaining pin, for retracting the retaining pin away from the bar receiving region; and wherein the at least one decoupling link that is decouplable from the removable link comprises: a link body having a first end and a second end; a hand portion having a bar receiving region formed at the first end of the body; a retractable retaining pin having a first end within the link body and a second end extending from the link body into the bar receiving region, the retractable retaining pin being slideable within a bore provided in the link body, the retaining pin for retaining the bar of the removable link in its bar receiving region; a biasing member, coupled to the retaining pin, for biasing the retaining pin towards the bar receiving region; and a retractor, coupled to the retaining pin, for retracting the retaining pin away from the bar receiving region; whereby the first end of the removable link is decoupled from the watchband by causing the retainable bar to be decoupled from the removable link by retracting the retaining pin of the removable link away from the bar receiving region sufficiently to allow the retainable bar to be removed from the bar receiving region of the removable link, and further whereby the second end of the removable link is decoupled from the decoupling link by causing the retracting of the retaining pin of the decoupling link away from the bar receiving region of the decoupling link sufficiently to allow the bar of the removable link to be removed therefrom.
  • 2. The watchband as claimed in claim 1, including a plurality of removable links.
  • 3. The watchband as claimed in claim 1, wherein the link body of the removable link comprises integrally formed, spaced apart first and second shoulders;wherein the bar of the removable link is secured to and between the first and second shoulders.
  • 4. The watchband as claimed in claim 1, wherein the biasing member of the removable link is a spring.
  • 5. The watchband as claimed in claim 1, wherein the retainable bar is coupled to another one of the plurality of interlocking links.
  • 6. The watchband as claimed in claim 1, wherein the retainable bar is a springbar coupled between a pair of lugs which themselves are part of a watch casing.
  • 7. The watchband as claimed in claim 1, wherein the link body of the removable link comprises a channel on one side thereof and the retractor includes a stem and an integrally formed head;wherein the channel includes sidewalls to restrict the slidability of the retractor therein.
  • 8. The watchband as claimed in claim 7, wherein the retaining pin of the removable link includes a pin body; and the stem of the retractor is secured within the pin body.
  • 9. The watchband as claimed in claim 1, wherein the link body of the removable link includes inner wall surfaces to prevent the retaining pin thereof from overextending within the bar retaining region of the removable link.
  • 10. A watchband comprising:a plurality of interlocking links, wherein the plurality of interlocking links includes at least one removable link that is decouplable from a decoupling link, wherein the removable link comprises: a link body having a first end and a second end; a hand portion having a bar receiving region formed at the first end of the body; a retractable retaining pin having a first end within the link body and a second end extending from the link body into the bar receiving region, the retractable retaining pin being slideable within a bore provided in the link body, the retaining pin for retaining a retainable bar in the bar receiving region; a biasing member, coupled to the retaining pin, for biasing the retaining pin towards the bar receiving region; and a retractor, coupled to the retaining pin, for retracting the retaining pin away from the bar receiving region; whereby the retainable bar is retained within the bar receiving region by the retaining pin, and whereby the retainable bar is decoupled from the removable link by retracting the retaining pin away from the bar receiving region sufficiently to allow the retainable bar to be removed therefrom.
  • 11. A method of reducing the length of a watchband, wherein the watchband comprises a plurality of interlocking links, at least one of which is a removable link and another of which is a decoupling link;wherein the removable link comprises a link body having a first end and a second end; a hand portion having a bar receiving region formed at the first end of the body; a bar coupled to the second end of the body; a retractable retaining pin, extending from the link body into the bar receiving region, for retaining a retainable bar in the bar receiving region; a biasing member, coupled to the retaining pin, for biasing the retaining pin towards the bar receiving region; and a retractor, coupled to the retaining pin, for retracting the retaining pin away from the bar receiving region; and wherein the at least one decoupling link that is decouplable from the removable link comprises a link body having a first end and a second end; a hand portion having a bar receiving region formed at the first end of the body; a retractable retaining pin, extending from the link body into the bar receiving region, for retaining the bar of the removable link in its bar receiving region; a biasing member, coupled to the retaining pin, for biasing the retaining pin towards the bar receiving region; and a retractor, coupled to the retaining pin, for retracting the retaining pin away from the bar receiving region; wherein the method comprises the steps of: removing a first retainable bar from the bar receiving portion of the removable link by retracting the retaining pin of the removable link away from the bar receiving region of the removable link sufficiently to allow the retainable bar to be removed therefrom; decoupling the second end of the removable link from the decoupling link by retracting the retaining pin of the decoupling link away from the bar receiving region of the decoupling link sufficiently to allow the bar of the removable link to be removed therefrom; and coupling the retainable bar to the decoupling link by the steps of: placing the first retainable bar into the bar receiving region of the decoupling link while the retractable retaining pin of the decoupling link is sufficiently retracted so as to allow the retainable bar to be placed into the bar receiving region of the decoupling link; and releasing the retractable retaining pin of the decoupling link while the retainable bar is within the bar receiving region of the decoupling link.
