Self-aligning rotary damper assembly
First Claim
1. A rotary damper adapted to engage a mating gear to dampen the rate of relative movement between a support panel supporting the rotary damper and an opposing structure supporting the mating gear, the rotary damper comprising:
- a rotatable wheel gear projecting away from a housing containing a damping fluid, the housing including a pair of upwardly projecting snap-in connection structures disposed on opposing sides of the wheel gear;
the snap-in connection structures comprising pairs of opposing legs projecting away from the housing in the same direction as the wheel gear;
the wheel gear being sized for insertion through a through hole in the support panel and the legs being adapted for insertion in snap-in relation through slots within the support panel substantially aligned with one another on opposing sides of the through hole, and wherein said slots are characterized by a width dimension which is smaller than the through hole, wherein the opposing legs in each snap-in connection structure are spaced at a distance which is smaller than the through hole such that the opposing legs are adapted for insertion in snap-in relation through slots having a width less than the through hole such that portions of the legs are supported in sliding relation on a surface of the support panel at positions outboard from the slots with all portions of the snap-in connection structures maintained outboard from the through hole and the housing is slidable relative to the support panel along a substantially linear travel path defined by the slots;
the wheel gear being spaced apart from at least one of the snap-in connection structures at a predefined distance selected to retain the mating gear in operative connection to the wheel gear during reciprocating sliding movement of the housing.

Abstract
A rotary damper with a toothed wheel gear projecting away from a housing having snap-in connection structures disposed on opposing sides of the wheel gear. The wheel gear may be inserted through a panel opening having a pair of opposing transverse slots. In the assembled condition, the housing with the connected wheel gear may slide linearly in the longitudinal direction of the slots to permit self-adjustment relative to an operatively connected mating gear. Proper meshing relation between the wheel gear and the mating gear is thereby maintained.
