Abstract

"DISPOSIçãO EM RODìZIO PARA CADEIRA GIRATóRIA". O presente modelo de utilidade refere-se a uma disposição construtiva introduzida em sistema de fixação das rodas ao eixo do rodízio de pés de cadeiras giratórias. A disposição construtiva em rodízio compreende um eixo das rodas (1) dotado de sulcos periféricos (2), que formam dentes extremos. Esse eixo (1) é solidarizado ao suporte do eixo (3) do corpo (4) do rodízio, sendo mancalizadas as rodas (5) em suas extremidades. Cada roda (5) possui um cubo (6) dotado de um orifício com um anel interno (7). A retenção da roda (5) se dá pelo encaixe do sulco (2) do eixo (1) no anel (7) do cubo (6) da roda (5). O suporte do eixo (3), que tem maior diâmetro que o cubo (6) da roda (5), possui uma cavidade cilíndrica (8) na sua face na qual penetra o cubo (6) da roda, ficando a sua extremidade sobreposta. Tal construção impede a entrada e o acúmulo de sujeiras entre esses dois componentes garantindo o perfeito funcionamento do rodízio. Opcionalmente, a porção mediana do eixo das rodas (1) pode possuir um recartilhado para melhor aderência no suporte do eixo (3) do rodízio para móveis."ROTATING ARRANGEMENT FOR SWIVELING CHAIR". The present utility model relates to a constructive arrangement introduced in the system of securing the wheels to the swivel chair foot caster axis. The caster construction comprises a wheel axle (1) provided with peripheral grooves (2), which form extreme teeth. This axle (1) is attached to the axle support (3) of the caster body (4), with the wheels (5) being driven at its ends. Each wheel (5) has a hub (6) provided with a hole with an inner ring (7). The retention of the wheel (5) occurs by fitting the groove (2) of the shaft (1) into the ring (7) of the hub (6) of the wheel (5). The axle support (3), which is larger in diameter than the hub (6) of the wheel (5), has a cylindrical cavity (8) on its face into which the hub (6) of the wheel penetrates, with its end overlapping. . Such construction prevents the entry and accumulation of dirt between these two components ensuring the perfect functioning of the caster. Optionally, the middle portion of the wheel axle (1) may have a knurl for better grip on the furniture caster shaft support (3).
