Fastening Clip Device

Abstract

A fastening clip device comprising arms of different length pivoted together about a transverse pin on one and the other side thereof, and elastic means which maintain two facing portions of said arms spaced apart, one end of one of said arms being bent substantially to U-shape to retain the end of the other arm against the action of said elastic means, characterized in that the arm of smaller length comprises two apertures positioned on one and the other side of the pin about which the two arms are pivoted, and by comprising a flexible puller which passes through said apertures, extends between the pin and the arm of greater length, and is fixed to the curved portion of said arm.

Description

The present invention relates to a fastening clip device.

Fastening clip devices are known for fastening the sides of sports jackets, shoulder straps for large bags, etc.

These known devices consist substantially of a clip fixed to a flexible strap and formed from two arms pivoted about a central pin and maintained elastically spaced apart by a spring. One of the two arms of the clip has a U-curved end to retain the end of the other arm and to form a seat for housing a ring fixed to another flexible strap.

A drawback of this clip is the considerable effort required to disengage the ring from the clip, as the ring has to be brought close to the curved portion with one hand, then the ends of the two contacting arms have to be pressed with the other hand to create a passage and the ring then passed through the passage bounded by the two spaced-apart arms.

An object of the invention is to eliminate these drawbacks by providing a fastening clip device which enables the ring to be disengaged easily and comfortably.

This and other objects which will be apparent from the ensuing description are attained according to the invention by a fastening clip device as claimed in claim 1.

A preferred embodiment of the present invention is further clarified hereinafter with reference to the accompanying drawings, in which:

FIG. 1 is an exploded perspective view of the fastening clip device according to the invention,

FIG. 2 is a longitudinal section therethrough on the line II-II of FIG. 3,

FIG. 3 is a plan view thereof,

FIG. 4 is a perspective view thereof,

FIGS. 5, 6 and 7 show the device in the same view as FIG. 2 during the disengagement of the ring.

As can be seen from the figures, the fastening device of the invention comprises substantially a clip 2 consisting of two arms 4, 6 pivoted together about a transverse pin 8 and maintained spaced apart at one end by a spring 10.

The arm 6 presents a U-bent end 12 and is provided at its other end with a slotted aperture 14 for engaging a strap 16.

The other arm 4 is substantially flat and comprises two transverse slotted apertures 18, 20 respectively, through which a flexible puller 22 is passed to extend below the pin 8, it presenting a free end and an end fixed into a slotted hole 24 provided in the curved portion 12 of the arm 6.

The fastening device of the invention operates in the following manner.

By overcoming the elastic reaction of the spring 10, the user inserts the ring 26, fixed to a strap 28, between the two arms 4 and 6 (see FIG. 2). During this insertion a side 30 of the ring 26 interferes with the puller 22, which is forced inside the two arms (see FIG. 5).

When the ring is to be disengaged from the clip 2, the puller 22 is pulled, this operation firstly causing the end of the arm 4 to withdraw from the curved portion 12 of the other arm 6 (see FIG. 6), and then causing the side 30 of the ring 16 to separate from the two arms 4 and 6.

On further pulling the puller 22 the portion 30 of the ring 16 completely leaves the clip, and the ends of the arms 4 and 6 again come into mutual contact (see FIG. 7).

From the aforegoing it is apparent that the fastening device of the invention enables the ring to be disengaged in a simple and comfortable manner using only one hand.

Claims

1. A fastening clip device comprising arms of different length pivoted together about a transverse pin on one and the other side thereof, and elastic means which maintain two facing portions of said arms spaced apart, one end of one of said arms being bent substantially to U-shape to retain the end of the other arm against the action of said elastic means, wherein the arm of smaller length comprises two apertures positioned on one and the other side of the pin about which the two arms are pivoted, and by comprising a flexible puller which passes through said apertures, extends between the pin and the arm of greater length, and is fixed to the curved portion of said arm.

2. A device as claimed in claim 1, wherein the puller consists of a band inserted through slotted apertures.

3. A device as claimed in claim 1, wherein the puller is fixed to the free end of the curved portion of the arm.

4. A fastening clip comprising a first and a second arm of different lengths, mounting means formed on opposite sides of said arms,a transverse pin extending laterally through said mounting means so that said arms can pivot thereabout,a spring situated between said arms to maintain said arms spaced apart,one end of said second arm being curved to a substantially U-shape to retain one end of said first arm therewithin under the force of said spring,a transverse slot formed through the bend in said second arm,a first aperture formed on one end of said first arm, and a second aperture formed on the other end thereof, said apertures being located on opposite sides of said transverse pin, anda release strap passes through said apertures in said first arm, below said transverse pin, and is secured within said transverse slot in said bend of said second arm,whereby said release strap, when pulled, forces the first arm to pivot about said transverse pin out of engagement with the bend of said second arm, thereby releasing any ring previously retained between said first and second arms of said clip.

5. A fastening clip as defined in claim 4, wherein said mounting means for said transverse pin comprises ears formed on opposite sides of said first plate, and cooperating ears formed on opposite sides of said second plate.

6. A fastening clip as defined in claim 4, wherein said first arm is smaller than said second arm, and one end of said first arm fits within the bend of said second arm.

7. A fastening clip as defined in claim 4, wherein said spring is seated upon said transverse pin to exert a force against the interior surfaces of said first and second arms.

8. A fastening clip as defined in claim 4, wherein said release strap passes downwardly through one aperture in said first arm, about said transverse pin, then passes upwardly through said second aperture in said first arm, and is then secured within the slot in the bend of the second arm of said clip.
