Buckle on which a female part having a receiving opening at one end and an adjacent locking edge on the opposite side to the opening, and a male part, having a locking portion and an activating portion, are designed to connect in releasable manner; the buckle being characterised by the fact that the locking and activating portions are formed on an intermediate portion and the free end respectively of a flexible tongue projecting from the male part in the insertion direction, the flexible tongue being connected to a further essentially-rigid contrasting tongue on the male part, the distance between the tongue and the locking portion on the flexible tongue being greater than the height of the receiving opening.
The present invention relates to a releasable buckle, particularly for bags, satchels and similar, the said buckle comprising an essentially-plate-like female part, the latter having a receiving opening at one end and an adjacent locking edge on the opposite side to the said receiving opening, and a male part comprising a locking portion, the latter engaging behind the locking edge when the male part is inserted inside the said receiving opening, and an activating portion located in front of the locking portion in the male part insertion direction. On known buckles of the aforementioned type, the activating and locking portions are formed respectively on the root portion and free end of a flexible tongue carried on the front end and facing the rear end of the male part, in the insertion direction of the latter inside the female part. The said male part is essentially a rigid plate having the said flexible tongue at one end and, at the opposite end, a member enabling connection to sheet material such as a belt or the flap on a bag or satchel. One of the main drawbacks on known buckles of the aforementioned type is that, for locking and releasing the male part inside the female part, the said flexible tongue is required to deflect considerably for enabling the locking portion on the said free end of the said flexible tongue to fit underneath the said locking edge and so enable passage of the same through the said receiving opening. Such entails relatively strong effort on the part of the user, relatively slow operation with the possibility of the buckle getting jammed, particularly when opened, and the danger of the flexible tongue being broken and the buckle thus being rendered unusable, owing to severe fatigue caused by the relatively severe bending strain the buckle is subjected to.
The aim of the present invention is to provide a releasable buckle of the aforementioned type involving none of the aforementioned drawbacks, i.e. one providing for fast locking and, particularly, fast release, that is strong and cheap to make, and which requires very little effort on the part of the user.
Number 1 in FIGS. 1 to 3 indicates a releasable buckle, particularly suitable for locking bags, satchels or similar and comprising a female part 2 and a male part 3, the latter being separable from the said female part and designed to connect with the same by insertion inside a receiving opening 4 formed on end 5 of the said female part 2. The latter comprises an essentially-flat plate 6 having, on its upper surface 7, a U-shaped bracket 8 formed integral with plate 6 and defining, on end 5, the said receiving opening 4, and, on the opposite side, a locking edge 9 adjacent to opening 4 and against which engages, in the locked position (FIG. 5), a respective locking portion 10, on the said male part 3, located behind a respective activating portion 11 on the said male part 3 in the insertion direction of male part 3 inside female part 2. According to the present invention, female part 2 presents a raised collar edge 12, the latter defining with surface 7 a cup-shaped housing 13 for the said activating 11 and locking 10 portions on male part 3, and a projecting portion 14 located in front of opening 4 in the insertion direction of male part 3. On end 15 opposite end 5 on female part 2, surface 7 presents a sloping portion 18 sloping downwards in the insertion direction of male part 3 and designed to receive activating portion 11 when male part 3 is inserted inside female part 2, as shown clearly in FIG. 4. Again according to the present invention, U bracket 8 is flared internally on its upper side in such a manner as to widen opening 4 on the opposite side to locking edge 9. For reasons of appearance, end 15 is preferably shaped in the arc of a circle. Flat plate 6 presents an essentially-rectangular bottom recess 20 housing a suitably thick metal plate 21 having respective cutting and locking tabs 22, the latter being preferably triangular in shape and designed to pierce any type of sheet material, e.g. leather or natural/synthetic fabric, for enabling assembly on the same of female part 2. Plate 6 thus defines, at the bottom, a connecting member for connecting part 2 to the said sheet material constituting, for example, a strap, belt or flap on a bag or satchel to which buckle 1 may be fitted. Tabs 22 are preferably formed by half-blanking plate 21, project perpendicularly from the same, outwards of recess 20, and are designed to bend 90° after piercing the said sheet material, in such a manner as to secure part 2 to the same. Plate 21 is clicked on to part 2 inside recess 20, the latter being defined, according to the present invention, by a pair of essentially-rigid, longitudinal ridges 24 (FIG. 3) arranged facing each other and formed along opposite longitudinal edges 25 of plate 6, and by a front tooth 27 formed, on the end 5 side, on the free end of a flexible tongue 28 formed integral with female part 2 and projecting from the U bracket 8 side, in such a manner as to define, together with the end part of opposite edges 25, the said projecting portion 14. Tongue 28 defines, at the bottom, receiving opening 4 and is designed to deflect in such a manner as to enable insertion of plate 21 underneath tooth 27, after first sliding the said plate 21 inside recess 20 underneath longitudinal ridges 24.
1. A buckle comprising: an essentially plate-like female part having a U-shaped bracket on its upper surface and a male part separable from the female part; said female part including a receiving cavity having towards one end an opening for receiving said male part, an adjacent locking edge on the opposite side of the said opening, both said opening and said locking edge being defined by said U-shaped bracket, and a slanting ramp portion comprising a portion of the inside surface of said cavity sloping downwards away from said U-shaped bracket in the male part insertion direction; said male part having a locking portion engaging behind said locking edge when said male part is inserted inside said receiving opening and an activating portion located in front of said locking portion in the male part insertion direction; said male part further having said locking and said activating portions formed on an intermediate portion and the free end respectively of a first flexible tongue projecting from said male part in the direction of its insertion; said male part also having a second essentially rigid contrasting tongue projecting beneath said first flexible tongue and essentially beneath said locking portion, the lower surface of said second rigid tongue being located, in relation to said locking portion, at a distance measured perpendicularly to the planes of said second rigid and first flexible tongues, greater than the height of said receiving opening; wherein said activating portion of said male part cooperates with said receiving opening and said ramp portion of said female part for insertion and retention therein.
5. A buckle according to claim 4, wherein each respective plate member on said male and female parts comprises a metal plate having respective cutting and locking tabs designed to pierce said sheet material and to bend 90°, and means upon said male and female parts for engaging said metal plates on to said male and female parts.
