. The present invention relates to extensible connectors for bracelets, wrist watch straps or bands,
etc.
In accordance with the present invention, the connector comprises a main link in which a 'ratchet member or link is slidably adjustable, and the main link is provided with a, detent --member for releasably securing the ratchet member in adjusted position, the construction and arrangement of these three parts of the connector being such as to facilitate the operation of the detent member and to eliminate the projection of .the detent member from the main link as in certain connectors of known construction. The
provision of an adjustable connector of this im- 2 x L? Fig. 3, but showing thefoldable links within the main or housing link;
proved construction and operation constitutes one of the objects of the present invention. 1
Further, in accordance with the preferred embodiment of this invention, the detent member ,is arranged in such relation to the main link that it appears as a part of said link rather than as a separate detent with the result that the appearance of the connector is considerably improved in comparison with certain connectors of known ;construction. The accomplishment of this result constitutes another object of the present invena. tion.
A further object of this invention i'sto provide a connector which is so constructed and arranged as to greatly reduce or eliminate thepossibility of accidental operation of the detent member for releasing the ratchet. a
A yet further object of the invention is generally to provide an extensible connector of improved construction and operation.
The above and other objects, features andadvantages of this invention will be full understood from the following description considered .in connection with the accompanying illustrative drawings.
In the drawings: Fig. 1 is an enlarged perspective view of an 'extensible connector embodying the present invention, the ratchet member being in its outwardly extended position and the foldable links being retracted from the main link;
, Fig. 2 is a bottom perspective view, on a larger scale, of the mainlink and the ratchet member;
' pivot pin 20. Also, as here shown, end-attaching Fig. 3 is a longitudinal sectional view of the connector, the foldable links being shown retracted from the main link but disposed in partially folded relation;
, Fig. 4 is a sectional view on the line 4-4 of Fig. 3;
" Fig. 5 is a sectional'view on the line 5-5 of Fig. '6 is a bottom perspective view of the ratchet member;
Fig. 7 is an enlarged longitudinal sectional view of the main or housing link; Fig. 8 is a perspective view of the adjacent en portions of the main link and of the detent member in separated relation and in the pro-assembly formsthereof. v
v Referring now to the drawings in detail, the extensible connector of the present invention comprises a main or housing link Ill, a ratchet member l2, slidable in said main link longitudinally thereofjand the foldable links l4 and I 6 which are pivotally connected to each other as indicated at !-8, and which are arranged to be housed within the main link i ii or to be retracted therefrom, said link l4 being pivotally connectedto the housing link in at one end thereof b the members 22 of any suitable construction are pivotally connected to the outer ends of ratchet member 12 and link 16 for the securement to the connector of the ends of a wrist watch band.
In accordance with the present invention a detent member 24 is disposed on the top of the main or housing link It! and extends longitudinally of the latter. As said housing link as well as the other links are usuall longitudinally curved, said detent member is likewise curved longitudinally thereof to conform generally to the curvature of the top oflink l0. Said detent member 24 is secured at one end thereof to the adjacent end of link l0 and is provided at its opposite end with an integral detent element 26 which has laterally projected catch portions 28 positioned to releasably engage the teeth 30 of the ratchet member l2at'a point externally of link I0. The detent member 24 may be connected to'the'link loin any suitable way but the illustrated construction which will now' b vdescribed is preferred As illustrated in Fig. ,8; the detent member 13pmvided with a reduced portion or neck 32 extending from the body portion of the detent member to the end portion 34 which is wider'than said neck. The link ID at the end thereof to which v the detent member isconnected is provided with a' projection 36 continuous with the top wall 38 of said 'link, said projection having a' recess 40. In assembling'detent member 24 and link lfl'the neck 32 of the detent member is positionedin recess 40 of the projection 36, and the endportion 34 ofthe detent member is bent under the adjacent" end portion of the inner'su'rface of top wall- 38, after which the portions 42 which are at opposite sides of the recess 40 of the projection 36 are bent into engagement with the end portion 34 of the detent member.
The main link Ill is of channel form and comprises in addition to the top wall 38 the laterally spaced side Walls 44 which as usual have inturned lower edge portions 45-. Said" side walls 44 are preferably dimensioned and shaped in relation to the top wall 33 so as to project above the upper or outer surface of said top wall, as.- clearly illustrated, see particularly Figs. and '7, to form a longitudinally extending groove in which the detent member is'positioned as'showm More particularly, the side walls 44 of link [0- have upper portions 46 which form the side walls of said groove, the bottom of which is constituted by the top wall 38 of the link. It will be'noted that, as shown in Figs. 3 and '7, the side walls of the groove increase progressively in depth from the end-of link ifl' to' which the detent member is secured toward the opposite end of said link,
whereby the groove similarly increases in depth.
' .of the side walls 44 of link H} are preferably dimensioned so as to project slightly above the outer surface of the detent member 24 in the ratchet-securingposition of said-detent member whereby to prevent accidental inward flexing movement of said detent member and thereby preventing inadvertent or accidental release of thedetent element 26 from the ratchet. On the other hand, when it is desired to release the ratchet member l2 for sliding movement longitudinally-of the main link It, this can be very easily accomplished by merely pressing on the top of detentmember 24-, preferably at the end thereof adjacent the detent element 26. It will be understood of course that the detent member 24 is made of spring metal stockso that it is flexibly movable toward and away fromthe. top38 of the main link l0 and that by reason-of the connection-of one endpf said detent members with the adjacent end'of link: l0,- and the engagement of the detent element'with the teeth of the ratchet member, the detent member is partlyiflexed toward saidtop wall 38 andis thus'spring-biased away from wall 38- for holding the detent element in releasable. engagement w'ith'the'teeth of the ratchet member,
- The ratchet member l2, which is preferably formed in; onev piece,-haslaterally'spaced longitudinal side portions 48 which define a. longitudinally eXtending slot 50 through which the de- .-tent element 26 projects for releasable engagement with the teeth 30 of the ratchet member. It
will benoted that said teeth are formed, as clearly illustrated'in Figs} 1, 3 and 4, on the lower edges of the longitudinal portions. 48 of the ratchet .memberso that the upward flexing movement. of the detent member 24 results in the engagement .of detent element 26 with said ratchet teeth while the downward flexing of said detentmember results in the. disengagement of the detent element from said ratchet teeth to release the ratchet member for slidable adjustment. The opposite ends of longitudinal portions 48 are preferably integral with the adjacent end portions 52 and 54. the latter being provided with an eye 56 for pivotal connection with the adjacent strap-end connector 22. The ratchet member I2 is guided for sliding movement in the main or housing link H! by the side walls 44 and by the inturned edge portions 45 of said side Walls in a well understood manner. Said ratchet member is provided with inturned end portions 58 which are slidably engag'e'able with the longitudinally extending projecting portions fill oi link 16 for releasably holding the foldablelinks I4 and It, in the folded condition thereof, in the main or housing link III in all normal adjusted positions of the ratchet member insaid'housing link.
Thus it is seen that the extensible connector described above is well adapted to accomplish the several objects of the present invention. It will beunderstood, however, that various changes in the details of construction and in the arrangement of parts may be made and that the invention may be embodied otherwise than as herein illustrated 0r described without departing from the underlying idea or principles of the invention. within the scope of the appended claims.
