A self-closing slide (10) is movable between an open position (Fig. 3) and a closed position (Fig. 2). The slide (10) includes a frame (12), a linear gear (14) on the frame (12) and a carriage (16) configured for movement along the frame (12). A biasing element (32) operably connects the frame (12) and the carriage (16) to bias the carriage (16) to the closed position. A pinion gear (24) is carried by the carriage (16) and is positioned for movement along the linear gear (14) with movement of the carriage (16) along the frame (12). A damper (44,48) is operably connected to the pinion gear (24) and to the carriage (16). An engagement gear (44) of the damper is movable between a first, engaged position in which the engagement gear (44) engages a projection (48) and a second, disengaged position in which the engagement gear (44) disengages the projection (48). When the carriage (16) is moved from the closed position toward the open position, the engagement gear (44) is in the second, disengaged position to disengage the damper so that the pinion gear (24) rotates freely. When the carriage (16) is moved from the open position toward the closed position, the engagement gear (44) is in the first, engaged position to engage the projection (48), damping rotation of the pinion gear (24) along the linear gear (14) and hence damping movement of the carriage (16). <IMAGE> |
