Abstract

The manufacturing process is for a ring for lacing boots or other articles of clothing. A blank is cut out in a single piece and is bent to form an eyelet tube or tubular rivet (1), for fixing it to the article. An elongate ring (2) is joined to the upper part of the tube. Opposite the ring there is a tongue (4) and this is folded (4a) over the upper opening of the eyelet to cover it and make it watertight. The inner (2a) and outer (3b) edges of the ring are rolled towards its base.

Description

Monobloc hook-hook for shoes and other articles of clothing, and process for its production.

The present invention relates to a one-piece hook-ring for shoes and other articles of clothing, for example leather and skin or imitation leather and skin.

It also relates to the method of manufacturing this hook-ring.

It is known to use ring hooks to remedy the drawback of lacing by means of eyelets fitted to the edges of the opening of the upper of the shoes, in particular of shoes with a rising stem, this drawback stems from the fact that the said edges are strongly pressed, during lacing, against the tongue of the shoe, which counteracts the perfect sliding of the lace in said eyelets.

According to a first embodiment of the known hook-rings, a ring produced using a metal wire is articulated at the upper part of an eyelet tube or tubular rivet used for fixing the hook ring on the leather or other material of the article to be fitted. This embodiment however has the drawback of being very crusty, because it requires the use of two .different materials (metal wire for the ring and strip for the eyelet tube) and an assembly operation of two constitutive elements. For this reason, these hook-rings are mainly used to constitute lace stops arranged a.the lower part of the edges of the slot of the rod, while one uses open hooks to form the other organs lacing equipping the remaining portion of said edges.

According to another embodiment, it is known to produce ring hooks formed in one piece and comprising an eyelet tube or tubular rivet secured to a metal band folded over the upper opening of said tube d 'eyelet, forming a firm hook allowing the passage of a lace. However, according to this embodiment, the axis of the hook is perpendicular to the axis of the eyelet tube, so that said hook forms a protrusion which, in use, can be crushed under impact and pinch the lace which, from then on, can no longer slide freely. For this reason, such hook-rings are also essentially used to constitute yaw stops.

The object of the present invention is in particular to remedy the drawbacks of known hook-rings.

This object is achieved thanks to the method of the invention which is mainly remarkable by the fact that one realizes, by cutting and stamping, a one-piece blank comprising: - on the one hand, an eyelet tube rigidly secured to a lace ring has in the same plane or substantially as that of the upper opening of said eyelet tube and, on the other hand, a tongue arranged opposite said passelacet ring; and in that said tongue is then folded over said upper opening so as to constitute a cover for eyelets.

The hook-ring according to the invention is essentially characterized in that it comprises a lace-passing ring formed in one piece with an eyelet tube, said lace-passing ring being arranged in the same plane or in a plane slightly oblique to the plane in which the eyelet cover is located, which is also formed in one piece with said eyelet tube and constituted by a tongue folded over the upper opening of the latter, the fold line of said eyelet cover being located opposite to said ring, with respect to the axis of said eyelet tube.

Thanks to this embodiment, a simple hook-ring is obtained, very economical, very robust and allowing excellent sliding of laces of any kind, without wear of the latter.

These aims, characteristics and advantages, and others still, will emerge more clearly from the description which follows and from the appended drawings in which
Figure 1 is a plan view of a blank obtained by cutting and folding.

ia Figure 2 is a longitudinal sectional view of this blank.

Figure 3 is a plan view of the completed one-piece hook-ring.

Figure 4 is a side view and in longitudinal section of this hook ring.

Figure 5 is a sectional view on a larger scale illustrating the section of the lace loop.

Reference is made to said drawings to describe an interesting example of implementation of the method and execution of the hook-ring according to the invention.

According to this process, a blank is produced by cutting and stamping using any suitable machine such as a hydraulic press, for example obtained from a strip or metal strip having the required characteristics. This blank formed in one piece comprises - an eyelet tube or tubular rivet 1, having for example a frustoconical shape; - A ring 2 secured to the upper part of said eyelet tube and disposed in the same plane as that in which the upper opening 3 of the latter is located; - a tongue 4 arranged opposite the ring 2 and also secured to the upper part of the eyelet tube 1.

The tongue 4 is then folded over the upper opening 3 of the eyelet tube, so as to constitute the eyelet cover intended to seal the fastener.

On the other hand, the ring 2 is bordered by folding down and rolling its internal edge 2a and its external edge 2b. During this planking action, the folded internal edge 2a can be crimped into the folded external edge 2b, or vice versa. The ring thus conformed has a substantially circular section and a recalling appearance. that of the rings made using a metal wire.

Finally, the ring 2 can be slightly raised so as to be in an inclined plane relative to the plane in which the eyelet cover 4 is located, said ring forming with the latter an angle p very open, for example of the '' from 1600 to 1700.

It is understood that the hook-ring- resulting from the implementation of the process which has just been described comprises a lace-pass ring 2 integral with the upper part of an eyelet tube 1 and formed in one piece with the latter * said lace loop ring- being disposed in the same plane or in an inclined plane 'P'-P' relative to the plane PP in which the eyelet cover 4 is located surmounting the upper opening 3 of said tube d 'eyelet. The eyelet cover 4 is also formed in one piece with the eyelet tube 1 and it is constituted by a tongue integral with the upper part of the latter and folded-above said opening, the fold line 4a of said tongue being located opposite the ring 2 with respect to the axis of said eyelet tube.

The inner edge 2a and the outer edge 2b of the lace ring 2 are folded down and rolled, as indicated above, said inner edge being pushed back towards the outside, while said outer edge is pushed back towards inside.

The lace-passing ring thus bordered does not have any sharp edges in contact with the lace and capable of promoting the wear of the latter.
