2 or 2 25' I'll-- LINK STRAP This invention relates to a link strap, particularly a bracelet, which consists of links that can be movably interconnected.

Link straps, particularly bracelets, are known which consist of articulated links and in which the links .con-

sist of link frames having detachable inserts, which may be ornamental. The individual links of such straps may be made by machine and can subsequently be provided with ornament. The link straps may then be used as ornamental bracelets or attached to watches.

The present invention enables the provision of special variations of ornament in a simple manner and improves the economy with which the strap can be manufactured. 1

To accomplish these objects, the link strap or bracelet is characterized according to the invention in that the inserts are provided at one end with end noses,

, are received by pockets at the hinge portions of the link actually been made by duplicating methods. The strap can be assembled in a simple manner, without need for soldering work, and can also be reduced or increased in length .in a simple manner. For this purpose the inserts received by the pockets at the hinge portions of the link frames expose transverse bores for receiving the hinge pins of the adjacent links and the extensions'of the inserts are held by the hinge pins at the hinge portions between extensions of the link frames. The link frames are formed at one end on the underside of their cross piece with recesses, which receive the extensions which extend from the other end of the adjacent frame and these extensions are provided with a transverse through bore for connection to the pin. The ornamental inserts provided at one end with edge noses and at the other end with extensions are preferably made by injection molding.

The link frame-may be provided with a retaining lip for receiving ornamental stones or the like and the inserts provided with the end noses and extensions may 2 form bottom members, which are preferably apertured like a frame.

according to the invention are shown by way of example in the drawing, in which FIGS. 1 to 3 are an underside view and side elevations showing a first link frame.

FIGS. 4 and 5 are sectional views taken on lines IV- IV and V-V, respectively, of FIG. 1.

FIG. 6 is a central sectional view taken through a composite bracelet link according to the invention.

FIGS. 7 and 8 are a top plan view and a side elevation, respectively, showing an. associated ornamental insert.

FIG. 15 isa sectional view taken on line XV-XV of FIG. 17 isa sectional view taken on line XVII--XVII of FIG. 18 but through a complete strap link.

FIGS. 18 and 19 are a top plan view and a side elevation showing a bottom insert for the strap link.

FIG. 20 is a perspective view showing a framelike bottom member as shown in FIG. 18 and FIG. 21 is a top plan view showing two strap links hooked together in accordance with the showing of FIG.11.

As is apparent from FIGS. 1 to 11 the first embodiment of the link strap according to the invention, e.g., in the form of a linkbracelet, consists of link frames 1 provided with detachable inserts 2 and 2a, which are' connected by pins 3. The ornamental inserts 2 are held end noses 4 leave end short of the closed rear ends of the pockets 5 and define therewith transverse spaces 6 in which end portions of the hinge pins 3 projecting laterally beyond the extension 8 are received and locked (see FIG. 6). To cover the connections, the link frames 1 are provided at one end in their crosspiece on the underside with recesses 9, which receive the extensions 8, which are provided at the adjacent frames 1 and offset at 10. The extensions 7 are correspondingly offset'at l 1. These pins are in register with and received by the respective spaces 6 to connect the links when the link strap is assembled.

In the second embodiment shown in FIGS. 12 to 21, the link strap, e.g., in the form of a link bracelet,consists also of link frames 21 provided with inserts 22, which in this case form bottom frames 22 and hold ornamental stones 22a in the link frames 21. The links are again connected by hinge pins 23. It is apparent that the link frames 21 are provided with a retaining lip (see FIG. 15) and the bottom inserts.22 just as in the first embodiment are provided at one end with end noses 24, which are received by pockets 25 of the link frames 21, so as to leave transverse spaces 26 exposed, in which opposite end portions of the hinge pin 23 of an adjacent link is received and locked (see FIG. 17). At the other end, the inserts 22 are provided with extensions 27, which at the hinge portions extend between the extensions 28 of the link frames 21 and are extending through aligned

bores

32 and 32 in the extensions joined by the pins 23. In this case, all link frames are formed to receive ornamental stones 22a and are provided attheir hinge portions at one end on the underside with edge recesses 29 to receive portions of the adjacent frame and at the other end with extensions 28v What I claim is:

l. A link strap comprising a plurality of links, each of which comprises a frame member; an insert member detachably mounted in said frame member, each of said frame members comprising first and second hinge portions at opposite ends thereof, one of said members being formed adjacent to said second hinge portion with pockets and the other of said members being formed with end noses received in said pockets, each of said insert members having adjacent to said first link portion an extension; and a hinge pin for each link located in said second hinge portion of said frame member of said link and extending through said first hinge portion and said extension of an adjacent link.
