ABSTRACT:
A fastening device or apparatus wherein mechanical connection and/or disconnection or electrical connection and/or disconnection is accomplished as a result of the deformation of an oval/ellipse shaped component--the deformable component--which may preferably have an elliptical aperture therethrough. Deformation may result from the application of a deforming force which causes the decrease in length of the major axis and a consequent increase in length of the minor axis of the ellipse. The deforming force may be applied by any known means such as by magnetic fields applied where the deformable component may have incorporated therein material which is sensitive and reactive to such magnetic fields or by the application of mechanical pressure from a piston driven by magnetic forces or hydraulic forces and/or forces created by temperature changes such as are known and found in a class of materials characterized as "SHAPE MEMORY ALLOYS". Thus the fastening device may be designed so that the forces causing deformation may be applied interior to the deformable component thereby permitting the pegs and/or holes to be located on the outer peripheral surface of the deformable component. Such a deformable component can cooperate with a non-circular cooperating component which is quite different from the substantially cylindrical/circular construction of the stud/male component which is insertable into the elliptical shaped aperture. The peg-and-hole combination being arranged as a part of the respective component so that there is a mating relationship between them when mechanical attachment or an electrical connection is to be achieved. The deforming force, no matter how it is generated is applied in such a manner so that the piston device physically and appropriately pushes or pulls on the deformable component in either the direction of the major or minor axis. Force from manual squeezing of the deformable component along the direction of the major axis may also be applied to cause the deformation and the subsequent connection or disconnection of the stud or cooperating components. More particularly, the invention is very simply based upon the deformation by any known means of force generation of an oval or elliptically cross-sectioned aperture and/or elliptical periphery which results in forces, due to the deformation and due to the characteristics of the material which cause the two components to interengage and the interengagement can be caused to be made or released by the application of the deforming force.
