Filed: 1954-08-30
Abstract: 752,172. Stud - and - socket fasteners. DOMENECH, G. A., and DOMENECH, V. A. Aug. 30, 1954, No. 25142/54. Class 44. A connecting device comprises in combination a resilient clamp 3 having a base 13 shaped like a curved disc and adapted to assume a stable concave or convex position and having on its periphery a plurality of gripping means 14, an outer casing 1, fixable to one (7) of the two parts which it is desired to connect and provided with means, e.g. flanges 4, 5 for permanently retaining in its interior the resilient clamp 3, and a male member 2 fixable to the second (12) of the two parts which it is desired to connect, the male member having in its side a circular depression 9 adapted to accommodate the ends of the gripping members of the clamp. When the parts of the device are separated, the base 13 has a concave shape viewed from its outer side and the ends of the gripping means 14 are at their maximum separation. When the parts of the device are pushed together, the inside of the base 13 bears near its periphery on an annular edge 15 of the male member and the edges of the flange 4 on the casing bears on the outside of the base but nearer to the periphery so that the base is caused to change from concave shape to. convex shape. This change of shape moves the ends of the gripping means 14 inwardly to engage the depression 9 in the male member to lock the parts of the device together. To unlock the device the centre of the base 13 is passed downwardly to cause the base to change from convex to concave shape and hence to disengage the means 14 from the depression 9. As shown, the base 13 is connected by a cover 16 and the disc is moved to unlocking position by pressure on a ball 18 positioned between the base and the cover with part protruding through an aperture in the cover. The ball and cover can, however, be omitted if desired. Also as shown the male member is hollow and has a dish-shaped member 19 positioned in its interior and loaded by a spring 20. In the unlocked position of the base 13, the member 19 bears against the centre of the underside of the base and tends to separate the male member from the casing. The member 19 can be omitted if desired, in which case the male member is made solid.
