A device adapted to stabilize an article of furniture on a support surface is formed as a wedge-shaped main body having upper and lower surfaces diverging from a common vertex to an end surface. A plurality of transverse rib teeth are on at least one of, but preferably both of, the upper and lower surfaces so that a plurality of devices may be stacked with the teeth preventing longitudinal slippage. The construction material is stiff, yet flexible and resilient, to help stabilize the article of furniture, and may be an anti-skid material. A cavity may be provided to enhance selected flexing, and ridges may be provided to prevent lateral slippage. The upper and lower surfaces have a common radius of curvature and may be planar or, respectively, convex and concave. The upper and lower surfaces may come together at a point, a line or a blunt nose to define the vertex. A bore may be formed through the body member for mounting and carriage.
A device adapted for insertion between a support surface and the lower support structure of an article of furniture placed thereon in order to help stabilize the article of furniture, comprising a body member formed of a relatively stiff, yet flexible material in a shape having an upper surface and a lower surface which have a common vertex and which diverge from one another to define a wedge-shaped configuration, said body member having a plurality of rib-like first teeth located on said upper surface and a cavity formed in the lower surface, said teeth oriented transversely to the direction of divergence of said upper and lower surfaces whereby said lower surface may be placed on said support surface with the common vertex defining an initial attack portion for insertion between the support surface and the article of furniture whereby said body member may be advanced until said upper surface contacts and supports the lower support structure to stabilize the article of furniture whereby said body member flexes under the weight of the article of furniture and in response to jarring forces impacting the article of furniture to further stabilize said article.
A device adapted for insertion between a support surface and the lower support structure of an article of furniture and the like placed thereon and operative to support and stabilize said article, comprising a main body member element and formed of a relatively stiff, yet flexible and resilient material, said body member having an upper surface and a lower surface having a common vertex and a common radius of curvature, said upper and lower surfaces divergently extending in a direction of divergence from said vertex, said body member having an end surface extending between said upper and lower surfaces at a location opposite said vertex and a pair of side surfaces extending between said upper and lower surfaces on opposite sides thereof, said upper surface provided with a plurality of first ribs formed transversely to the direction of divergence and said lower surface provided with a plurality of second ribs formed transversely to the direction of divergence, said vertex defining an attack portion for said wedge-shaped element whereby the device may be inserted between the support surface and the lower support structure and advanced until the upper and lower surfaces contact the support surface and the lower support structure to stabilize the article, said body member having a longitudinal channel and a longitudinal ridge structure on each side of said first ribs and on each side of said second ribs with said first and second ribs sized to fit with one another and are operative such that a plurality of devices may be stacked with the teeth on adjacent facing ones of said upper and lower surfaces engaged and with side edges of engaged ones of the teeth abutting respective ridge structures whereby both longitudinal and lateral slippage is prevented.
