An integrated joint assembly fastener is described for removably securing two adjoining members together along flat mating surfaces. A housing is provided with an off-center circular bore in which a rotatable element is held captive. The bottom end of the rotatable element has an offset connecting post which extends perpendicular to a slit provided in a rear sidewall of the housing. Stationary wedges on the housing front project from opposite side of the slit. A pair of connecting dowel head sections project from the front opening and are engaged by the offset connecting post of the rotatable element. The dowel head sections have a gripping ridge section at a free end and an inclined abutment formation for sliding engagement against the wedges. By rotating the rotatable element, the gripping ridge sections of the dowel head are pulled back and wedged outwardly, laterally. Displacement inwardly towards the housing front causes each gripping head section to engage within the materials in bore of the adjoining member and to pull back and tighten the members together.
La présente invention concerne un dispositif de chevillage intégré pour le montage de meubles permettant de solidariser de façon amovible deux éléments connexes par des faces planes correspondantes. Une virole est retenue prisonnière dans un logement ménagé dans une cuvette ronde excentrique. Un tenon excentré prend naissance sur le fond de la virole vers une fente de la paroi latérale postérieure du logement. La façade du logement est pourvue de coins fixes dépassant du côté opposé de la fente. Deux demi-têtes de goujons prenant naissance dans l'ouverture antérieure viennent au contact du tenon excentré de la virole. L'extrémité libre des demi-têtes de goujons est garnie de rives à griffes. Un patin incliné vient jouer contre les coins. La rotation de la virole provoque un retrait des segments à griffes des demi-têtes de goujon, et leur écartement latéral en coin. La traction vers la face antérieure du logement amène les griffes des demi-têtes à prendre dans la matière de l'alésage de l'élément connexe, et à rapprocher les éléments connexes en les serrant.
