Abstract
1508578 See - saw CHARLES WICKSTEED & CO Ltd 31 Oct 1975 [18 Nov 1974] 49877/74 Heading A6M A see - saw comprises a support 10 on which a board 11 is pivoted at 12 the board having a depending member 13 which swings pendulum fashion with the board and has a roller 14 at its lower end, there being between the member 13 and a transverse member 19a on the support, resilient means which provides resistance to tilting of the board such as to minimise or obviate a hard impact of the board at the ends of its tilting movement. As shown, the roller 14 co - operates with cam surfaces 15b, 16b of a pair of overlapping levers 15, 16 pivoted at 15a, 16a respectively. The levers 15, 16 contact a roller 18 in a bracket 17 supported on a leaf spring assembly 19. The cam surfaces 15b, 16b are shaped so that as the board 11 tilts the levers are depressed against the resistance of the spring. The leaf spring may be replaced by a coil spring (indicated in dash - dot lines) and further buffers 20 may be provided on the support. In a second embodiment Fig. 4 (not shown) levers 21, 21a are pivoted on a common axis (22) on a transverse support member (23) their cam surfaces being in V-form and the resilient means is provided by buffers (24, 24a). In a third embodiment Fig. 5, (not shown) the cam surfaces are formed by a track (27) on a resilient block (26) mounted on the transverse member 23.
