Title: Improvements in Snap Catches
Inventor: MOODY GEORGE HENRY
IPC: E05C19/02
Filed: 1967-05-10
Abstract: 1,188,996. Catches. METROPOLITAN PLASTICS Ltd. 6 June, 1968 [10 May, 1967], No. 21634/67. Heading E2A. A snap catch for a door comprises a first complementary part which includes a retention member 2 having a flat surface and converging side edges, the member having a recess H extending into it from its flat surface in the direction of the thickness of the member to form a passage from one converging side edge of the member to the other, the boundary edges of the passage having complementry substantially V form profiles apexed towards the narrow end of the retention member, and a second complementary part which includes an element 8 having springy engagement with the retention member in the fastening condition, the element 8 terminating in a rider block 10 the element being so disposed in use in relation to the retention member that pressure on the second complementary part presses the rider block towards and against the converging side edges of the retention member and deflects the element until the rider block snaps into the recess to be retained in fastening condition and thereafter further pressure in the same direction allows movement of the rider block out of the recess and subsequent pressure in the opposite direction causes complete disengagement of the two parts. The movements of the rider block and element 8 are illustrated in Fig. 2. In the construction shown the retaining member 2 is carried by a plate 3 by which it is secured to the door and the element 8 is contained in a casing 1 which is secured to the door frame the retention member 2 entering the casing to engage the element 8 during closing movement of the door. The element 8 is pivotally mounted on a back plate 4 of the casing and is biassed by a pair of springs 5, 9 the spring 5 urging a plunger 6 into engagement with an abutment on one side of the member 8 and the spring 9 being trapped between an abutment on the plate 4 and the other side of the element 8. The arrangement is such that the spring 5 is compressed by the movement of the rider block along the sloping side edge A of the retention member during the door closing movement and urges the rider block into the recess to the fastening position the spring 9 being compressed after the rider block has moved partially out of the opposite side of the recess by engagement with the side edge B of the retention member and restoring the element 8 to its original disposition in relation to the retention member when the rider block has cleared the edge B during door opening movement. In a modification the element 8 is made of resilient material and the springs and plunger are omitted.
