Clamp

Abstract

The clamp is of the type which may be actuated by means of an auxiliary actuating member. It consists of two parts, namely a clip (1), whose two branches are connected via a thin part (7) and a slit housing (8) in which an actuating member (2), consisting of a pin with a diameter greater than the diameter of the housing (8) or a cam equipped with a radial arm, is accommodated. The introduction of the pin or, respectively, the rotation of the cam results in closure of the clip, causing the thin part (7) to bend resiliently.

Description

FIELD OF THE INVENTION

The subject of the present invention is a clamp consisting of a clip and an actuating member for closing the clip by separating the two parts of the clip against the action of a resilient means.

PRIOR ART

A clamp of this type is known from Patent CH 631,520. This clamp consists of a clip in two parts articulated and held open by the action of a spring catch. The clip may be closed by a cam secured to a lever. In the closed position of the clip, the lever actuating the cam is located in the extension of the clip, because the clamp is intended to be mounted on suspenders or on belts, or to hang clothing or paper. The manufacture of a clamp of this type requires the assembly of the clip and of the spring, operations which are not readily performed automatically and which have a considerable effect on the cost price of a clamp of this type.

SUMMARY OF THE INVENTION

The aim of the present invention is to produce a clamp of the same type, but of substantially simpler manufacture and which, in particular, does not comprise a spring.

The clamp according to the invention is defined in that the clip and the resilient means are made in a single piece, having two clip branches connected at their base by a thin part forming a resilient hinge and, on the other side of this thin part, a cylindrical housing, of circular section or otherwise, parallel to the thin part, open laterally along a generatrix opposite said thin wall, and intended to receive the member for actuating the clip.

The clamp according to the invention therefore comprises only two, the clip and the actuating member.

The actuating member may be a simple pin or a cam securely attached to a radial arm for its rotary movement.

The clamp according to the invention may not only be used for holding flat, thin objects together, but also as a support for an object intended to be fastened temporarily to another object. In particular, the clamp may be equipped with a watch which may thus be fastened rapidly and in a detachable manner on an article of clothing, a bracelet or the like. In the event that the clamp comprises a cam equipped with an actuating arm, this arm may act as a support for the clamp, enabling the watch to be placed in an oblique position on a table.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The clamp shown in FIG. 1 consists of a clip 1 and an actuating member 2.

The clip 1 is made in a single piece from injectionmolded synthetic material, such as nylon (registered trademark) or polyester or polyamide with a fiber filler. It has two clip arms 3 and 4 which are parallel and equipped on their opposing faces with projections 5 and 6. The two arms 3 and 4 of the clip are connected at their base by a relatively thin part 7 which can bend resiliently. On the other side of this thin part 7, the clip has a cylindrical housing 8 extending parallel to the part 7 and open laterally along a slit 9 extending along a generatrix opposite the part 7. The cylindrical housing 8 is thus itself limited by two arms 10 and 11. The actuating member 2 consists, in this first embodiment, of a cylindrical pin equipped with a frustoconical end 12 and a short radial arm 13 at the other end. The diameter of the pin 2 is slightly greater than the diameter of the cylindrical housing 8 of the clip. In order to tighten the clip, the pin 2 is forced into the housing 8. Because its diameter is greater than the diameter of the housing 8, the pin 2 separates the two arms 10 and 11 limiting the housing 8, which results in the arms 3 and 4 of the clip moving closer together, as represented in FIG. 2. In order to open the clamp, the pin 2 is removed via its arm 13. The clamp may act as a support for an object, for example a watch 14, whose outline has been represented in dot-dash lines in FIG. 2.

The second embodiment represented in FIGS. 4 to 7 comprises a clip which is virtually identical to the clip 1 of the first embodiment. It differs therefrom by a branch 4' which is shorter than the branch 3 and by a housing 8' with an oval section. Moreover, the ends 15 and 16 of the cylindrical housing 8, have a section which is larger than the rest of the housing. The member for actuating the clip consists of a cam 17 in the form of a cylinder of oval section approximately identical to that of the housing 8' and whose ends 18 and 19 have slightly larger sections and are housed in the ends 15 and 16 of the housing 8 so as to lock the cam 17 axially in the housing 8'. The cam 17 is equipped with a radial arm 20 having a bent part 21 extending parallel to the cam 17. When the arm 20 is directed perpendicularly to the clip, as represented in FIG. 4, the oval sections of the cam 17 and of the housing 8' of the clip coincide such that the clamp is opened. When the arm 20 is folded back parallel to the clip, the cam 17 separates the arms 10 and 11 of the housing 8', which results in closing of the clip, as represented in FIG. 5.

This clamp may also carry an object, for example a watch 14. In this case, the arm 20 may also be used as a support for holding the watch in an oblique position, placed on a table as represented in FIG. 8.

The clamp according to the first or second embodiment, equipped with a watch, may be fastened on any flat object or flat part of an object having a suitable thickness. Thus, the watch may be clipped onto an article of clothing, for example on a pocket, on a shirt or on a jacket lapel. It may also be fastened on a key ring equipped with a fob or on a cord in order to be carried around the neck, for example. It may, in particular, be carried on a bracelet, as represented in FIG. 9, turning it into a wrist watch, or on the cuff of a shirt, as represented in FIG. 10, which turns it into a strapless wrist watch. The very small part projecting laterally from the bracelet or the cuff, respectively, will be noted.

The clamp according to the invention, equipped with a watch or otherwise, may, of course, be used quite simply as a clamp for holding sheets of paper together, for example bank bills.

By means of two clamps according to the invention connected by a cord, it is possible to produce a security device for fastening a pocketbook or a wallet. One of the clamps is fastened to the article of clothing and the other to the pocketbook or wallet, respectively.

Of course, the clamp may carry any other object of suitable size, such as a compass, medal, photoframe, and the like.

The clamp could be produced in metal, particularly by injection of an aluminum alloy.

The section of the actuating cam and the section of the housing for this cam do not need to be oval.

It should be emphasized that the word "cylindrical" is taken in its widest geometrical sense, it being possible for the section of the cylinder to be circular or otherwise.
