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 by using one hand to operate a puller, or release strap.
This and other objects which will be apparent from the ensuing description are attained according to the invention by a fastening clip device as described hereinafter.
A preferred embodiment of the present invention is further clarified hereinafter with reference to the accompanying drawings, in which:
As can be seen from the figures, the fastening device, according to the invention, comprises 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. Ears 9 are situated on opposite sides of arm 4 and depend beneath arm 4, at its midpoint.
The arm 6 presents a U-bend 12 at one end, and is provided, at its other end, with a slotted aperture 14 for receiving strap 16. Ears 13, 15 extend upwardly from arm 6, at its midpoint.
The other arm 4 is substantially flat, and is smaller than plate 6. Transverse slots 18, 20 are formed in arm 4, one slot on each side of pin 8. Flexible puller, or release strap 22, passes downwardly through slot 18, below pin 8, and exits upwardly through slot 20. The free end of puller, or release strap 22, is then secured within slot 24 located in bend 12 of arm 6, as shown in
The fastening device of the invention operates in the following manner.
By overcoming the elastic reaction of spring 10, the user inserts the ring 26, fixed to strap 28, between the two arms 4 and 6 of clip 2 (see
When the ring 26 is to be disengaged from the clip 2, the puller 22, or release strap, is pulled. This operation initially causing the end of the arm 4 to withdraw from the bend 12 of the other arm 6 (see
On further pulling of the puller 22, the leading side 30 of the ring 16 completely leaves the clip, and the ends of the arms 4 and 6 again come into mutual contact (see
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.
