JPH01110302A - Link arm band - Google Patents

Abstract

PURPOSE: To provide a link arm band that is easy to be assembled and disassembled, by a method wherein a clamp member is arranged between inner links, one of pins provided on an outer link is formed into a complete pin and the other into a half pin. CONSTITUTION: Half pins 6 of outer links 1 are inserted into holes of inner links 2 until the side faces of enlarged parts 9 of the half pins 6 come into contact with each other. A clamp member 3 is moved between the inner links 2 so that both the enlarged parts 9 pass through a lead opening 8 together and reach the inside of a holding cut 7. Thereby, the outer links 1, the inner links 2 and the clamp member 3 are rigidly connected together in the band lengthwise direction. To fix such band units along the length, a complete pin 11 that serves as a connecting pin for an adjacent single link at the same time is introduced into cuts 4 of the inner links 2 and a cut 10 of the clamp member 3.

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. direction, by approximately half the length of the single link;
It relates to a type which can be connected in a link-like manner to the corresponding ends of laterally adjacent individual links by means of pins oriented at right angles to the longitudinal direction of the band.

In link armbands known from the prior art, the assembled single links are fixed by transforming the ends of the pins as stops or by screwing together stops at the ends of the pins. Such a configuration is
It's not a stupid thing that takes a lot of time to manufacture, and it doesn't look beautiful.

OBJECTS AND SUMMARY 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 for Solving the Problem The means taken to solve the above-mentioned problem is that one inside link is in contact with each of the mutually facing sides of two outside links, and furthermore, one inside link is in contact with the mutually facing sides of two outside links, and A clasp member is disposed between them, and one of the two holes disposed on the outer link passes through the notches of all the single links arranged in parallel and the notches of the clasp member, and laterally. The clasp member is formed as a complete pin extending to an oppositely located outer link, the other pin of the outer link being fixedly disposed in the outer link and passing through a notch in the adjacent inner recess. It is formed as a pin half that protrudes into the holding notch almost to the center of the band, and the free ends of the pin half that face each other can be engaged with each other by a clasp member to be connected. .

Effects of the Invention Due to the configuration of the invention, the clasp member has the same shape as the individual link on the outer side of the link armband, which allows it to be used not as a functional component but as a decorative component. You can see it. Easy plug-in assembly and disassembly are possible without destroying or deforming the components. Despite the simple relative motion of a single link,
Single links cannot be separated from each other.

The opposing free ends of the two pin halves each have a radial enlargement, and the corrugations are held together to block relative axial movement of the pin halves. A locking connection is achieved in a simple manner by the clamp-like grip provided by the recess. 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 extending outwardly from the retaining cutout perpendicularly to the longitudinal direction of the pin halves and allowing the introduction of both radial enlargements 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 easily produced by a turning process.

If the enlarged part in the radial direction is a spherical part, and the two spherical parts that protrude from each other form a shape close to one sphere, the circumference of the band can be adjusted in the longitudinal direction with a play circumference that limits manufacturing errors. Single links located parallel at right angles can pivot 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 armband 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. The individual links are staggered by approximately half the length.

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.

Particularly, as is clear from FIG. 3, the inner link 2 is formed with cutouts 4 as penetrating holes extending perpendicularly to the band longitudinal direction at both ends facing in the band longitudinal direction.

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.

At the other end of the outer link 1 a pin half 6 is arranged, which protrudes towards the outer link 1 located opposite 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 T formed at one end of the clasp member 3. It has reached that point.

The holding recess 7 simultaneously clamps the two radial widenings 9 which are arranged at the free ends of the pin halves 6 facing each other and also prevents the relative stroke movement of the pin halves. It has a cross section that cuts off.

Perpendicular to the longitudinal direction of the pin half 6, a retaining notch 7
A lead-in opening 8 is formed outwardly from the lead-in opening 8, which has a cross-sectional shape such that the radial enlargement 9 of both pin halves 6 can be introduced together from the outside into the holding recess T. have.

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. The complete pin 11 is inserted into this notch 10 as well as the notch 4 of the adjacent inner link 2, and the end of the complete pin 11 is inserted into the notch 5 of the outer link 1.
It is arranged so that it can penetrate inside.

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 pin half 6 is shown installed in the blind hole 13 of the outer link 1.

d and hh in FIG. 6, where the radial enlargement 9 is cylindrical.
s 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 at least approximately rectangular cross-sectional shapes.

7 and 8, the holding notch 7 and the introduction opening 8 are formed by a blind hole, and the blind hole may be 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 embodiment illustrated by df in FIGS. 7 and 8, the holding notch 7 and the introduction opening 8 are formed by holes extending through the band in the longitudinal direction.

In all the embodiments shown in FIGS. 7 and 8, a slit-shaped opening 9 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. has a smaller cross-section than the cross-section of the radial enlargement 9 and through the opening 14 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 . This ensures that 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 passes through the recess 4 of the inner link 2 without difficulty. be able to.

As shown in FIGS. 4 and 5, the clasp member 3 is located either immediately adjacent to the inner link 2 (FIG. 5) or offset by half a length with respect to the inner link 2. be done (
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 widenings 9 together pass through the introduction opening 8 and into the retaining cutout T. 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 gap 711 that simultaneously forms the connecting pins of adjacent individual links in the longitudinal direction of the band is inserted into the notch 4 of the inner link 2 and the notch of the clasp member 3. You will be guided through 10.
