Definitions

  • An expansion bracelet. particularly for Wristwatches, has a row of connected links.
  • Each of these links has a plate member, a pair of solid outer members connected to said plate member at opposite lateral sides thereof, as seen with respect to the elongation of the row, and a solid inner member which is located between the outer members and partly projects beyond them in longitudinal direction of the row.
  • the inner member has an underside which faces towards the plate member and is provided with a pair of transversely extending channels.
  • a pair of substantially C- shaped brackets are provided, each having a bight portion pivotably received in one of the channels, and a pair of leg portions.
  • the leg portions of one of the brackets are pivotably connected to the plate member so that this one bracket can be tilted longitudinally of the row out from between the outer members of the link.
  • a pair of biassing springs are provided, each surrounding one of the bight portions. The biassing spring associated with the one bracket permanently opposes the tilting of the latter.
  • the other bracket is connected in the same manner with a plate member of adjacent link, and its associated biassing spring also opposes its 8 Claims, 4 Drawing Figures [75] Inventor: Rolf Schaudel,
  • the present invention relates generally to a bracelet, and more particularly to an expansion bracelet, espe-' cially for Wristwatches.
  • an expansionbracel'et particularly for Wristwatches, in a row of connected links each of which comprises a plate member having a pair of first edge portions extending transversely of the row, and a pair of second edge portions extending longitudinally of the row.
  • a pair of solid outer members are provided, each being connected to one of the second edge portions and being spaced from one another transversely of the row.
  • a solid inner member is located between the outer members and in part project beyond them in direction longitudinally of the row.
  • the inner member has an underside facing towards the plate member and provided with a pair of transversely extending channels.
  • a pair of substantially C-shaped brackets is provided.
  • Each of these has a bight portion which is pivotably received in one of the channels and a pair of leg portions.
  • the leg portions of one of the brackets are pivotably connected to one of the first edge portions of the plate member so that this one bracket can be tilted longitudinally of the row out from between the outer members of the link.
  • a pair of biassing springs are. received in the respective channels in engagement with the respective brackets, and the one associated with the one bracket permanently resists the tilting of the same.
  • the other bracket is to be connected with an adjacent link of the row.
  • a bracelet so constructed is, evidently, an expansion bracelet with all the advantages of the same.
  • it has the desired massive character in that both the outer members and the inner member are of solid cross-section rather than being hollow and formed of sheet .metal.
  • the bracelet can thus be readily configurated in terms of its surface configuration and of a desired variation of its width, for instance a continuous variation of the same.
  • FIG. 1 is a top view of an expansion bracelet according to the present invention, in non-expanded condition
  • FIG. 2 is a fragmentary top plan detail view, partly in section, showing a portion of the bracelet in FIG. 1 but in expanded condition;
  • FIG. 3 is a partly sectioned side elevation of the portion in FIG. 2'
  • v FIG. 4 is an exploded perspective view, showing the components of a link of the novel bracelet.
  • FIGS. 1-4 one exemplary embodiment of the invention, shown as a wristwatch expansion bracelet l.
  • the bracelet 1 comprises a row of connected links which together form a center row of members 2 that is bounded laterally by two outer rows 3 composed of members 4 and 4', respectively.
  • each-link of the novel expansion bracelet is composed of one of the solid cross-section inner members 2 and two of the solid cross-section outer members 4,4 which are located at the opposite lateral sides of the respective member 2.
  • a plate member 5 extending transversely of the elongation of the row and having substantially T-shaped lateral edge portions 6,6 (see FIG. 4) and transverse edge portions which extend between the edge portions 6,6.
  • One of these transverse edge portions is identified with reference numeral 7 and formed to tubular configuration, defining a passage which is open at its opposite ends.
  • the other transverse edge portion is identified with reference numeral 8 and formed to hook-shaped configuration so that the passage which it defines is open not only at its opposite ends but also laterally.
  • the plate member 5, which is of sheet metal, is formed with one or more (only one shown) profiling 9 which serves as a reinforcement for the plate member 5, i.e., to reinforce it against bending.
  • the mutually facing edge faces 10 of the members 4,4 are each provided with a slot 11 extending in parallelism with the elongation of the row of links, and the end portions 6,6 of the plate member 5 are each received in one of these slots and rigidly connected therein, for instance by means of press-forming or the like.
  • the members 4,4 and 5 constitute a unit with one another.
  • the link further comprises a solid cross-section inner member 2 which in the non-expanded condition of the bracelet.(compare FIG. 1) is located halfway between the members 4,4 whereas its other half projects outwardly from between them in the longitudinal direction of the bracelet, being located between corresponding members 4,4 of the next adjacent link.
  • the lateral edge faces 12,12 of each-member 2 are partly recessed as indicated in FIG. 4 so that a projection 13 is obtained. Downwardly below the projections 13 the edge faces 12,12 are provided with a pair of bores forming passages 14 which each extend from one of the edge faces to the other.
  • Each of the. passages 14 accommodates a helical spring 16 (only one shown) which is provided at its opposite ends with transversely extending projecting portions 17,17.
  • the purpose of the slots 15 is to permit the ready insertion of these springs 16 into the respective passages 14, which is accomplished in that the projection 17 or 17 at that end of the spring 16 which is to be the leading end as the spring is inserted, is made to move through the respective slot 15 during such insertion.
  • Each of the passages 14 further coacts with a substantially C-shaped bracket (only one shown in FIG. 4), a bight portion 19 of which extends through the respective passage as well as through the spring 16 therein. The insertion of these brackets, identified with reference numeral 18, is of course again made possible by the presence of the slots 15.
  • Each bracket can freely turn within the respective spring 16.
  • the two leg portions at the opposite ends of the bight portion 19 are located outside the member 2.
  • One part 20 of each leg portion is located in the clearance created between the respective members 4,4 and the member 2, due to the presence of the recess in the end faces 12,12, and another part 21,21 of the respective leg is received in ei? ther the passage formed by the edge portion 7 or the passage formed by the edge portion 8.
  • the legs or more particularly the parts 21,21 thereof are freely pivotable in these respective passages.
  • the parts 20 are protected and concealed from view by the projecting portions 13.
  • the bracket 18 is permanently tilted by the action of the spring 16 to a position inwardly of the link, in which the member 2 is located halfway between the members 4,4, the term halfway here referring ,to the longitudinal direction of the bracelet.
  • the spring action is overcome and the member 2 is moved outwardly; from between the members 4,4 by tilting of the associated bracket 18 in the corresponding direction, to the position shown in FIGS. 2 and 3.
  • the spring will restore the member 2 v to its former position.
  • these bracelets be adjustable in their length, to accommodate them to thicker or thinner wrists. According to the present invention this can be readily done by adding or removing individual links. It is merely necessary to move the parts 21,21 of a respective bracket 18 out through the open side 22 of the passage defined by the hook-shaped edge portion of a plate member 5, so that an entire link can be removed or, conversely, can be added.
  • An expansion bracelet particularly for wristwatches, comprising a row of connected links, each of said links comprising a plate member having a pair of first edge portions extending transversely of said row, and a pair of second edge portions extending longitudinally of said row; a pair of solid outer members each connected to one of said second edge portions and being spaced from one another transversely of said' row; a solid inner member located between said outer members and in part projecting beyond them in direction longitudinally of said row, said inner member having an underside facing towards said plate member and provided with a pair of transversely extending channels; a pair of substantially C-shaped brackets, each having a bight portion pivotably received in one of said channels and a pair of leg portions, the leg portions of one of said brackets being pivotably connected to one of said first edge portions of said plate member so that said one bracket can be tilted longitudinally of said row out from between said outer members; and a pair of biasing
  • one of said firstedge portions is formed to tubular configuration and defines an open-ended passage
  • the otheriof said first edge portions is formed to hook-shaped configuration and defines a passage which is open at its ends and also intermediate the latter, said leg portions of said one bracket being partly received in one of said passages.
  • leg portions each include one part which is spaced from and substantially parallels said bight portion and is received in said one passage, and another part which connects said one part and said bight portion and is located between said inner member and a respective one of said outer members.
  • biasing springs are helical springs having spaced ends each of which is provided with a projection extending transverse to the elongation of the respective spring, each of said springs surrounding one of said bight portions under torsional prestress with one of its projections engaging said inner member and the other of its projections engaging one of said other parts of the respective bracket.
