Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a link armband, for example a decorative or watch armband, having single links arranged in rows parallel to each other, said single links extending along the length of the band. the individual links are offset in the direction by approximately half the length of the single link, and each single link is laterally adjacent at each longitudinally oriented end of the band by pins oriented at right angles to the longitudinal direction of the band. It relates to a type that can be connected in the form of a link with the corresponding end of a single link.

BACKGROUND OF THE INVENTION In known link armbands, the assembled single links are fixed by transforming the ends of pins as stops or by screwing together stops at the ends of the pins. Such a configuration is not only time-consuming to manufacture, but also has an unattractive appearance.

OBJECT OF THE INVENTION It is an object of the invention to provide a link armband of the type described above which is easy to assemble and disassemble.

Means to solve the problem The measures taken to solve the above problem are 2.
One inner link abuts each of the two outer links on opposite sides, a clasp member is disposed between the two inner links, and one pin disposed on the outer link is configured to It is formed as a complete pin that extends through the notches of all the single links arranged in parallel and the notches of the clasp member to the laterally opposite outer link, the other pin of the outer link being , formed as a pin half that is immovably disposed on the outer link and projects through a notch in the adjacent inner link to approximately the center of the band in the retaining notch of the clasp member; The mutually opposing free ends of the clasp member are capable of being engaged and connected to each other by means of a clasp member.

Effects of the Invention With the arrangement of the invention, the clasp member has the same shape as the individual link on the outer side of the link armband, so that it is not used as a functional component, but as a decoration. It can be seen as a constituent part. Easy plug-in assembly and disassembly are possible without destroying or deforming the components. Despite simple relative movement of the single links, the single links do not become dislodged from each other.

the mutually opposite free ends of the two pin halves each have one radial enlargement;
In addition, a positive connection is achieved in a simple manner in that the two enlarged parts are clamped together by a retaining recess in such a way that relative axial movements of the pin halves are blocked. . Furthermore, it is advantageous for the cross-section of the holding recess to correspond significantly to the cross-section of the two radial widenings.

in that the clasp member has an introduction opening through which the two radial enlargements extending outwardly from the retaining recess perpendicularly to the longitudinal direction of the pin halves can be introduced together. , a configuration that is easy to manufacture and easy to assemble is obtained.

This allows a plug-in assembly that can also be carried out by machine.

If the radial extension is of cylindrical design, it can be manufactured simply by a turning process.

If the enlarged part in the radial direction is a spherical part, and the two spherical parts protruding from each other form a shape close to a single sphere, it is perpendicular to the longitudinal direction of the band around the play that limits manufacturing errors. A single link located in parallel with can rotate to some extent.

If the radial enlargement is large enough to pass through the notch in the inner link, the radial enlargement can be constructed integrally with the pin half.

Uniformly closed sides of the outer link are achieved by the fact that the recess in the outer link for receiving the complete pin is designed as a blind hole that opens towards the inner link.

Embodiment The link arm band shown in FIGS. 1 to 5 is composed of a plurality of rows of individual links having substantially the same shape and arranged in parallel with each other, and the individual links are arranged in parallel in the longitudinal direction of the band. They are staggered by approximately half the length of the individual links.

In this case, between the two outer links 1, inner links 2 abut on the mutually opposite sides of the outer links, and between the inner links 2 there is provided a fastener that corresponds approximately in outer dimension to the other single link. A gold member 3 is arranged.

In particular, as is clear from Fig. 3, the inner link 2
A notch 4 is formed at both ends facing in the longitudinal direction of the band as a penetrating hole extending perpendicularly to the longitudinal direction of the band.

Further, the outer link 1 is also provided with a notch 5 extending perpendicularly to the band longitudinal direction at one end facing in the band longitudinal direction, but this notch is blind and opens toward the adjacent inner link 2. It is formed as a hole.

A pin half 6 is arranged at the other end of the outer link 1 and projects towards the outer link 1, which is located oppositely at right angles to the longitudinal direction of the band.

The pin halves 6 of the two outer links 1 face each other and each pass through a cutout 4 in the inner link 2 to the center of the band in a retaining cutout 7 formed at one end of the clasp member 3. It has reached that point.

The holding recess 7 simultaneously clamps the two radial enlargements 9 arranged at the free ends of the pin halves 6 facing each other and also blocks the relative stroke movement of the pin halves. It has a cross section that looks like this.

Perpendicularly to the longitudinal direction of the pin halves 6, an inlet opening 8 is formed outwardly from the holding recess 7, in which the radial enlargement 9 of both pin halves 6 extends. Together, they have a cross-sectional shape that allows them to be introduced into the holding notch 7 from the outside.

At the end of the clasp member 3 opposite to the holding notch 7, a notch 10 is formed as another penetrating hole at right angles to the longitudinal direction of the band.
A complete pin 11 is further inserted into this notch 10 as well as within the notch 4 of the adjacent inner link 2.
1 is arranged so that the end portion of the outer link 1 projects into the notch 5 of the outer link 1.

As shown in FIGS. 6a and 6d, the pin half 6 can be constructed in one piece with the outer link 1.

Furthermore, as in the embodiment shown in FIG. 6b, the pin half 6 is stepped at its end on the side of the outer link and fixedly mounted in a corresponding stepped hole 12 of the outer link. You can also do it.

In FIG. 6c, the blind hole 1 of the outer link 1 is
The pin half 6 is shown mounted within 3.

d in FIG. 6, where the radial enlargement 9 is cylindrical.
With the exception of the embodiment indicated by f in FIG. The two spherical bodies of the pin halves that protrude from each other form a shape close to a single sphere.

The clasp members 3 shown in FIGS. 7 and 8 all have a cross-sectional shape that is at least approximately rectangular.

In a to c of FIGS. 7 and 8, the holding notch 7 and the introduction opening 8 are formed by blind holes, and the blind holes are In this example, the opening is in the longitudinal direction of the band, and in the embodiments b and c in FIGS. 7 and 8, it is opened diagonally outward at an angle with respect to the longitudinal direction of the band.

In the embodiments d to f of FIGS. 7 and 8, the holding notch 7 and the introduction opening 8 are formed by holes passing through in the longitudinal direction of the band.

In all the embodiments shown in FIGS. 7 and 8, a slit-shaped opening 14 is provided in the range of the introduction opening 8 and the holding notch 7 at right angles to the longitudinal direction of the band.
is provided, the cross section of which opening 14 is smaller than the cross section of the radial widening 9 and through which the pin half 6 is guided to the holding recess 7.

The radial enlargement 9 is formed by forming an annular groove 15 spaced apart from the free end of the pin half 6 . By this,
The cross section of the radial enlargement 9 corresponds to the cross section of the pin half 6, so that the pin half 6 with the enlargement 9 can pass through the recess 4 of the inner link 2 without difficulty.

As shown in FIGS. 4 and 5, the clasp member 3 is either placed immediately adjacent to the inner link 2 (FIG. 5) or offset by half a length with respect to the inner link 2. (Figure 4).

Assembly of the link armband is shown in FIG. First, the pin half 6 of the outer link 1 is passed through one hole of the inner link 2 until the end surfaces of the enlarged portions 9 of the pin half 6 abut each other. The clasp member 3 is then moved in the longitudinal direction of the band between the two inner links so that the two radial enlargements 9 together pass through the introduction opening 8 and into the retaining cutout 7 . This causes the outer link 1, the inner link 2 and the clasp member 3 to be immovably connected to each other in the transverse direction of the band.

In order to fix such a unit also in the longitudinal direction of the band, a complete pin 1 is provided which simultaneously forms a connecting pin for adjacent individual links in the longitudinal direction of the band.
1 is guided through the cutout 4 of the inner link 2 and the cutout 10 of the clasp member 3.
