Abstract

A fastening device or apparatus having at least two parts or components wherein reliance is on the deformation of an oval/ellipse shaped aperture which deformation results from the insertion of a stud component into the aperture which is formed within a socket component. The present invention permits the attachment of the two components and the release of such attached components both steps being achievable using the squeezing or pinching forces on only the periphery of so called socket component and exertable with the use of one hand; more specifically the use of the fingers of one hand. More particularly, the invention is very simply based upon the deformation by a substantially cylindrical shaped member of an oval or elliptically cross-sectioned aperture which results in forces, due to the deformation and due to the characteristics of the material in which the aperture in located, which cause the two components to interengage and the interengagement can be caused to be released by the simple squeezing or pinching of only the socket component using the fingers of one hand. The stud and socket components may be adapted to have a plurality of interengagement discs on the stud component and at least one recess within the aperture of the socket component which recess cooperates with one of the discs of the stud component to result in the interengagment of the two components when the stud component is inserted into the socket component aperture. Where there is more than one recess in the aperture of the socket component each of the recesses may interengage with one of the discs of the stud component. The resulting interengagement will be adjustable in that the stud portion will be more or less into the aperture and as the number of disc/recess interengagements increases so do the security of the connection of the two components increase. There may also be two "stud components" a first and a second which may be connected together end-to-end using a socket component adapted to interengage with each of the two stud components. The end-to-end interengagement may be made and released by the one hand deformation of the socket component - that is the changing of the aperture from ellipse to oval by squeezing parallel to the major axis and then releasing allowing the aperture to tend toward an elliptical shape which results in the engagement of the two stud components. Release is accomplished by simply squeezing along the major axis causing deformation of the aperture to the circular/oval cross section allowing the dissengagement of the stud components. The fastener of the instant invention can thus be engaged and disengaged having access to only the socket component.
