DESCRIPTION:
BRIEF SUMMARY
The object of the invention is a bracelet for the jewelry and watch making industry, composed of several parallel rows of combined elements which are connected in a flexible manner by link members whereby neighboring rows are connected with each other by other link members. Bracelets of this kind are well known, and their flexibility for laying them around the wrist is sufficient.
Nevertheless, one has known up to now only bracelets on which these elements of one row were staggered, in the longitudinal direction, with regard to the neighboring row or rows. Such a staggering was necessary in order to link the ends of all elements by means of simple elements such as transverse rods or shafts which pass through all rows, from one edge of the bracelet to the other. Instead of these rods or shafts link members in form of a strip with rolled-up ends have also been used, these members having the same shape and the same dimensions as the combined elements themselves. In this manner a solid bracelet was realized which nevertheless has the flexibility of a chain, but that way of creating a bracelet was only possible with the staggering already mentioned, which not only imposed restrictions in the shape and the production of the bracelet but also necessitated so-called half-elements, i.e. elements of reduced length at the ends of the bracelet.
It is one object of the invention to overcome these deficiencies and to create a bracelet in which in all rows neighboring combined elements are disposed side by side over their entire length, thus forming not only longitudinal but also transverse rows.
It is another object of the invention to simplify manufacturing of the bracelet by providing combined elements which are made up of a minimum of parts.
A preferred embodiment of the bracelet according to the invention is illustrated in the drawings in which
FIG. 1 is a partial view of a braid of the bracelet,
FIG. 2 a side view of an upper element along line II--II of FIG. 3,
FIG. 3 a view of the upper element from below,
FIG. 4 a connecting mesh between combined elements, and
FIG. 5 a view of a bottom plate
FIG. 6 a side view of two combined elements of the inner row of the braid.
According to FIG. 1, the bracelet which, by means of its braids, is attached in a known and hence only schematically illustrated manner to a watch 1, is composed of several rows A, B, C etc., e.g. three rows, each row being composed of combined elements 1, 2, 3 etc. Said elements 1, 2, 3 etc. are rectangular in this embodiment and arranged in such a way that their longer edges meet themselves side by side. This arrangement differs from the prior art in which the elements of one row, e.g. those of row B, are staggered, in longitudinal direction, with regard to the elements of the neighboring rows A and B, in order to permit the rear ends of the elements of these rows and the forward ends of the row B to be linked by a rigid tranverse rod or shaft about which all elements may pivot in order to assure the necessary flexibility of the bracelet; identical rods or shafts are also provided for the forward ends of the elements in rows A, C and the rear ends of the elements of row B.
As can be seen from FIGS. 2, 3 and 5, each combined element 1, 2, 3 of longitudinal rows A, B, C is composed of only two parts, namely an upper element 4 and a bottom plate 5, which renders these combined elements very simple and easy to produce. Upper element 4 which constitutes the visible side of the bracelet (when it is worn) comprises an upper plate 6, a number of pillars 7, here four, which are vertically attached to the lower side of upper plate 6, and a central abutment 8. Pillars 7 are in this embodiment arranged in the middle of each edge of upper plate 6 and have a height H. They may have a generally square section, with one edge rounded (for reasons of manufacture) as shown, or any other suitable cross-section. Central abutment 8 which preferably has the same or a cross-section similar to the one of pillars 7, is of a height h that is reduced, compared with the height
