Abstract

The mortise and tenon joint has a tenon in the form of a retractable, expanding insert. The insert is made from two lengths cut from the same metallic section with the outer edges then notched so that the two pieces interlock when placed back-to-back. The lower edges have a cylindrical profile and house a hinge pin. They are held together by a spring clip. The assembly is inserted into a slot in one of the components and the expanding screws is introduced through a side hole. The notched ends of the insert are introduced in the mortise of the second component and opened by screwing in the expanding screw.

Description

La présente invention concerne les pièces mécaniques utilisées pour l'assemblage de profiles, panneaux, ou autres éléments, fixées encastrées dans un élément et assurant la fixation avec un autre par serrage dans une partie femelle qu'il comporte, par exemple gorge d'un profilé. The present invention relates to mechanical parts used for the assembly of profiles, panels, or other elements, fixed embedded in an element and ensuring the fixing with another by clamping in a female part which it comprises, for example groove of a streamlined.

D'une part, les dispositifs connus de ce genre, mis en place encas trés, ont une saillie en débord : la partie mâle qui viendra s'insérer pour serrage, comme dit ci-dessue. Ceci empêche le montage par présentation frontale d'un élément entre deux autres fixes et oblige donc à une manipulation qui suppose de la place disponible pour une rotation, ou un basculement (par exemple) et, à défaut de place, oblige à un démontage d'autres éléments. On the one hand, the known devices of this kind, installed in a very flush fashion, have an overhanging projection: the male part which will be inserted for tightening, as said above. This prevents mounting by front presentation of an element between two other fixed and therefore requires handling which assumes space available for rotation, or tilting (for example) and, in the absence of space, requires dismantling of other elements.

D'autre part ces dispositifs sont mis en oeuvre à partir de deux pieces de profils différents et complémentaires, mises en action par l'intermédiaire de pièces accessoires (vis,cames, ressorts etc.), et les impera- tifs de solidité de l'assemblage imposent à l'ensemble de la piece une epaisseur incompatible avec l'encastrement dans un élement minte et/ou le serrage dans une partie femelle étroite. On the other hand, these devices are implemented from two parts of different and complementary profiles, put into action by means of accessory parts (screws, cams, springs etc.), and the imperatives of solidity of the 'assembly impose on the whole of the piece a thickness incompatible with the embedding in a thin element and / or the tightening in a narrow female part.

La pièce d'assemblage selon l'invention élimine ces inconvénients. The assembly piece according to the invention eliminates these drawbacks.

En effet: D'une part elle est réalisée à partir de deux pièces demême profil, rendues complémentaires par simples découpes symétriques et emboitées l'une dans l'autre. Ceci permet de conserver une epaisseur compatible avec les impératifs dits ci-déssus et facilite la fabrication, les deux pièces, de même profil, étant fabriquées avec un mme outil (pour emboutissage, moulage, filage, ou autre), puis decoupées selon le besoin.Indeed: On the one hand it is made from two parts of the same profile, made complementary by simple symmetrical cuts and nested one inside the other. This keeps a thickness compatible with the above requirements and facilitates manufacturing, the two parts, of the same profile, being manufactured with the same tool (for stamping, molding, spinning, or other), then cut as required. .

D'autre part, mise en place encastré, elle est rétractable dans son logement, sans aucun débord. Partant, elle permet l'insertion frontale, puis la fixation, après sortie de la partie mâle, d'un élement, entre deux autres déjà fixés, sans besoin de place (planche 1/6). On the other hand, built-in installation, it is retractable in its housing, without any overhang. Therefore, it allows the front insertion, then the fixing, after leaving the male part, of an element, between two others already fixed, without the need for space (plate 1/6).

Planche 1/6 : exemple d'application, installation d'une entretoise mobile entre deux éléments fixes. Plate 1/6: example of application, installation of a mobile spacer between two fixed elements.

Planche 2/6 : coupe et plan du profil, avec exemple de découpe. Plate 2/6: section and plan of the profile, with example of cutting.

Planche 3/6 : modification du profil (ou variante) du profil, à son extrémité recevant un axe. Plate 3/6: modification of the profile (or variant) of the profile, at its end receiving an axis.

Planche 4/6 : même modification, avec exemple de découpe, pour recevoir l'axe. Plate 4/6: same modification, with cutting example, to receive the axis.

Planche 5/6 : Douille calibree, pour renforcement des profiles, ou autres éléments, selon la dureté des matériaux, permettant le mouvement avant/arrière de la pièce d'assemblage retractable, sans gêner la pièce de serrage (vis par exemple) et assurant un renfort au point avant rde blocage par cette dernière. : Plan, élévation et coupe avec mise en place dans un élément de bois. Plate 5/6: Socket calibrated, to reinforce the profiles, or other elements, according to the hardness of the materials, allowing the front / rear movement of the retractable assembly part, without interfering with the clamping part (screws for example) and ensuring a reinforcement at the point before blocking by the latter. : Plan, elevation and section with installation in a wooden element.

Planche 6/6 : Vue perspective de la pièce d'assemblage, avec projection de pièces complémentaires. Plate 6/6: Perspective view of the assembly part, with projection of additional parts.

Les deux parties mobiles de la pièce d'assemblage sont constituées d'un même profil, soit un profilé métallique ou plastique, soit une tôle emboutie etc. Ce profil (planche 2/6) est coupé à la longueur désirée, qui deviendra la hauteur de -la piece d'assemblage. Puis il subit a chaque extrémité des découpes, symétriquement opposées, de façon à obtenir, par réunion de deux tronçons dudit profil, face à face : à une extrémité, une charnière recevant un axe (planches 3/6, 4/6, 6/6), à l'autre, des dents alternées qui se croisent (planche 6/6). The two moving parts of the assembly part are made up of the same profile, either a metal or plastic profile, or a stamped sheet, etc. This profile (plate 2/6) is cut to the desired length, which will become the height of the connecting piece. Then it undergoes, at each end, symmetrically opposite cutouts, so as to obtain, by joining two sections of said profile, face to face: at one end, a hinge receiving a pin (planks 3/6, 4/6, 6 / 6), to the other, alternating teeth which intersect (Plate 6/6).

L'extrémité charnière reçoit un ressort qui assure la position fermée. L'une des deux parties reçoit la piece de poussée (planche 6/6). The hinge end receives a spring which ensures the closed position. One of the two parts receives the pushing piece (plate 6/6).

La pièce de poussée permet (planche 6/6, vis) permet - la manipulation avant/arrière de l'ensemble en position fermée - le serrage par poussée (pression) - le blocage, en position serré, ouverte, par butée, avec renfort éven te d'une douille (planche 5/6). The pushing piece allows (board 6/6, screws) allows - the front / rear manipulation of the assembly in the closed position - the push-in tightening (pressure) - the blocking, in the clamped, open position, by stop, with reinforcement even a socket (plate 5/6).

La pièce d'assemblage logée dans un élément mobile, ses dents viennent mordre, par écartement, dans une partie femelle d'un autre élément, assurant le vèrouillage des deux.The assembly part housed in a mobile element, its teeth bite, by spacing, in a female part of another element, ensuring the locking of the two.

Le dispositif objet de l'invention facilite les assemblages mécaniques de tout oupartie des éléments couramment utilisés pour le montage de meubles, structures de stands et matériels d'exposition ou de signalisation, installations et aménagements d'architecture intérieure etc, par exemple les assemblages de profilée plastiques ou métalliques ou de bois, de panneaux divers.  The device which is the subject of the invention facilitates the mechanical assemblies of all or part of the elements commonly used for the assembly of furniture, stand structures and exhibition or signaling materials, installations and arrangements of interior architecture, etc., for example the assemblies of plastic or metal or wood profile, of various panels.
