Description

La présente invention concerne un fermoir destins h à assurer la fermeture ou l'assemblage d'articles de confection tels que des sacs, des sacoches et dea trousses. The present invention relates to a clasp intended to ensure the closure or assembly of ready-made articles such as bags, saddlebags and kits.

Les fermoirs utilisés actuellement sont constitués de deux parties principales dont l'une, femelle, fixe sur l'une des faces de l'artiole, comporte un pontet en forme d'arceau et dont l'autre, ma- le, solidaire du rabat, comporte un organe de verrouillage rdtraota- ble en forme de bossage, rappelé vers I'extdrieur par un ressort, dont la face extérieure est inclines de fagon & permettre l'engagement soue le pontet de la partie femelle et la compression progressive du ressort, jusqu' & obtention du verrouillage, sous l'action du ressort, lorsque le pontet a franchi l'arête du bossage. La ddsolida- risation des deux parties est obtenue par simple effacement du bossage sous l'action d'un effort extérieur. The clasps currently used are made up of two main parts, one of which, female, fixed on one of the faces of the artiole, comprises a trigger guard in the form of a hoop and the other, which is integral with the flap. , comprises a retractable locking member in the form of a boss, biased towards the outside by a spring, the outer face of which is inclined so as to allow engagement under the trigger guard of the female part and progressive compression of the spring, until the lock is obtained, under the action of the spring, when the trigger guard has crossed the edge of the boss. The separation of the two parts is obtained by simply erasing the boss under the action of an external force.

Ces fermoirs classiques pressentent l'inconvénient d'être compo s8s d'au moins quatre pièces; ce qui complique leur fabrication et leur assemblage, et grève les prix de revient sans apporter d'avanta gos b l'utilisateur. These conventional clasps sense the disadvantage of being composed of at least four pieces; which complicates their manufacture and assembly, and strikes the cost prices without providing the user with advantage.

Aussi, diverses solutions ont-elles été envisagées en vue de diminuer le nombre des composants et de réduire le prix de revient de l'ensemble. Also, various solutions have been envisaged with a view to reducing the number of components and reducing the cost price of the assembly.

Parmi ces solutions, on peut citer celles dUcrites dans les brevets français 2
- 1.184 207 du Il Octobre 1957, concernant un fermoir constitue d'un verrou & rainure, coopérant avec un arceau, qui se caractérise par le fait que le verrou est constitué à partir d'une lame élastique métallique repliée, dont l'élasticité propre permet la suppression du ressort de rappel.Among these solutions, mention may be made of those described in French patents 2
- 1.184 207 of October 11, 1957, concerning a clasp consisting of a lock & groove, cooperating with a hoop, which is characterized by the fact that the lock is formed from a folded elastic metal blade, whose own elasticity allows the removal of the return spring.

- I. 386 171 du I2 Décembre I963, concernant un fermoir dont la partie mâle, ou verrou, réalisé en matière plastique, est constitué d'un feui-llet souple replié, comprenant une sous-palette sensiblement plane, servant à la fixation sur le rabat, et d'une palette comportant une saillie formant bossage de verrouillage. Les deux parties, réalisées en une seule pièce, sont réunies par un raccord courbe permettant l'articulation. Comme dans la solution décrite au paragraphe ci-dessus, l'élasticité de la matière est utilisée pour remplacer le ressort. - I. 386 171 of I2 December I963, concerning a clasp whose male part, or lock, made of plastic material, consists of a folded flexible sheetlet, comprising a substantially flat sub-pallet, used for fixing on the flap, and a pallet having a projection forming a locking boss. The two parts, made in one piece, are joined by a curved connection allowing articulation. As in the solution described in the above paragraph, the elasticity of the material is used to replace the spring.

- 2.131 039 du 30 Mars 1971, concernant un fermoir dont la partie malus, solidaire du rabat, comporte, & sa partie inférieure, une pièce en matière plastique injectée, présentant une ou plusieurs languettes repliées, exerçant, par leur élasticité propre, une force sous un poussoir métallique rapport6, obtenu par déformation d'une lame métallique. Dans ce mode de réalisation, l1élasticité propre du poussoir est renforcée par celle de la languette de la pièce en ma tière plastique. - 2,131,039 of March 30, 1971, relating to a clasp whose malus part, integral with the flap, comprises, & its lower part, a piece of injected plastic material, having one or more folded tabs, exerting, by their own elasticity, a force under a metal push rod report6, obtained by deformation of a metal blade. In this embodiment, the inherent elasticity of the plunger is reinforced by that of the tongue of the plastic part.

Ainsi, comme on le voit, les perfsotionnements apportés jusqu' alors aux fermoirs classiques, ont consisté principalement à éliminer le ressort de rappel du verrou en utilisant l'élasticité propre de la matière constituant le verrou et & faire appel aux matières plastiques, en tout ou partie, pour réaliser les composants. Thus, as can be seen, the improvements made until then to conventional clasps, consisted mainly of eliminating the return spring of the lock by using the inherent elasticity of the material constituting the lock and using plastic materials, in all or part, to make the components.

Toutefois, dans certains domaines tels que la maroquinerie, un effet esthétique est exigé ainsi qu'une grande sécurité de fonctionnement et une résistance suffisante aux efforts tant longitudinaux que transversaux; ce qui élimine l'utilisation de matières plastiques pour réaliser la partie mSle-et pour assurer le rappel du bossage vers l'extérieur et entraîne la remise en question de la constitution du pontet lorsque celui-ci est réalisé en matière plastique. However, in certain fields such as leather goods, an aesthetic effect is required as well as great operational safety and sufficient resistance to both longitudinal and transverse forces; which eliminates the use of plastics to make the mSle-part and to ensure the return of the boss to the outside and leads to the questioning of the constitution of the trigger guard when it is made of plastic.

Le fermoir selon l'invention, vise à remédier aux inconvénients présentés par les solutions évoquées ci-dessus, sans pour autant éli- miner le recours aux matières plastiques, notamment pour réaliser le pontet. C'est pourquoi l'organe de verrouillage, ou partie mole, est fabriqué en une seule pièce, obtenue par découpage formage en grande série d'une bande métallique de largeur appropriée, ayant gne bonne tenue aux efforts et A la corrosion et permettant d'obtenir un effet esthétique répondant aux goats des utilisateurs, et le pontet est fabriqué, lui aussi, en une seule pièce,par moulage d'une matière plastique, & l'aide d'une presse & injection. The clasp according to the invention aims to remedy the drawbacks presented by the solutions mentioned above, without eliminating the use of plastics, in particular for making the trigger guard. This is why the locking member, or mole part, is manufactured in a single piece, obtained by cutting forming in large series of a metal strip of appropriate width, having good resistance to stresses and corrosion and allowing d '' obtain an aesthetic effect corresponding to the tastes of users, and the trigger guard is also manufactured in one piece, by molding a plastic material, using a press & injection.

L'utilisation de pièces uniques obtenues en faisant appel & des machines universelles de grande production, pour réaliser ce fermoir, offre l'avantage d'éliminer les reprises et les assemblages toujours coûteux, sans que cela nuise & l'esthétique et à la fiabilité de fonctionnement du dispositif. The use of unique pieces obtained by using large-scale universal machines to make this clasp offers the advantage of eliminating rework and assemblies, which are always costly, without compromising aesthetics and reliability. of the device.

Le mode de réalisation choisi pour constituer les deux parties, a été tout particulièrement étudie en vue d'obtenir et d'assurer la conservation dans le temps d'une résistance suffisante aux efforts de désolidarisation, quel que soit leur sens d'application, ainsi qu'aux The embodiment chosen to constitute the two parts has been particularly studied with a view to obtaining and ensuring the preservation over time of sufficient resistance to the separation efforts, whatever their direction of application, as well that

Claims

abrasive and corrosive actions.

It should be noted that the friction of a metal part against a plastic part, considerably reduces noise compared to conventional all-metal clasps.

This clasp is mainly characterized in that the female part includes a housing for the wrong part, combined with a retaining bridge and in that the male part, produced from a metal strip by cutting and closing, includes a boss limiting the erasure of the elastic part forming a ramp and in that the end of said elastic part is provided with a device ensuring its longitudinal and transverse attachment to the boss and limiting its movement relative thereto.

The housing produced in the female part consists of a hollowed-out prism provided with an opening at its base and a cutout, taking on the shape of the elastic part, forming a ramp, of the mule part, on one on his side.

The retaining bridge of the malt part, in the housing arranged in the female part, is constituted by the strip of material located at the base of the prism and delimiting the cut located longitudinally on one of the sides of the latter. This trigger guard is provided with a rim which covers the end, forming a retainer, of the elastic part of the male part, so as to limit the deflection and to keep it slightly recessed with respect to the outer edges of the cutout arranged in the 'one side of the prism constituting the housing.

The boss limiting the erasure of the elastic part of the male part is obtained by stamping.

The device making the elastic part of the mile part integral longitudinally and transversely with the boss which it comprises, consists of several lugs penetrating into orifices cut out in the upper part of the boss.

The pins are obtained by cutting and forming at the extramit6, forming a retainer, of the elastic part of the malus part.

The end of the lugs is provided with a flare, a beo or a bar opposing their exit from the orifices provided in the boss and a permanent deformation of the part & polish.

Other features and advantages will appear in the
