Figure 1 shows a spring catch assembly 10 adapted to provide support for a vertically movable table, drawer or the like when it is moved to a new position. Figure la shows a portion of a drawer 12 in a normal, at rest position. The drawer is supported at one end by a fixed cylinder assembly 14. Assembly 14 comprises a piston rod 16 movable within cylinder housing 16. The upper end of the piston rod is attached to a support head 18. Attached to one side of head 18 is spring catch member 20 comprising a flexible steel spring 22 and a steel bar 24 slidably mounted on the inside surface of spring 22 by rivets 25,26. In the position shown in Figure lb, the operator raises the drawer until it clears the bottom of catch member 20. The spring 22 is then pressed inward. Bar 24 is moved downward and drawer 14 lowered until edge 28 of bar 24 engages the top surface of cylinder housing 16. In this position, the weight of the drawer exerts a downward pressure on edge 28 ensuring that the drawer is maintained in this catch position.
