US 4,109,320 A · Attaching assembly

Abstract

An assembly is provided which is adapted to be used in attaching a secondary unit, such as a face protective device, to a primary unit, such as a safety helmet. The helmet is of rigid material and has the lower peripheral edge thereof provided with a flange forming a gutter or trough. A gap is formed in the flange so as to enable the assembly to be slidably mounted on and removed from the primary unit flange. The assembly includes a bracket having a base portion adapted to be in slidable supporting engagement with a segment of the exterior wall surface of the primary unit. The bracket also includes a first extension extending laterally from the base portion and slidably positioned within the trough at a predetermined location, and a second extension offset from said first extension and disposed outside the trough and in sliding engagement with the flange. The extensions coact with one another to resiliently grip the flange therebetween and retain the bracket in the predetermined location. Coacting with the bracket base portion is a means for connecting thereto the secondary unit.

An assembly for use in attaching a secondary unit to a primary unit wherein the latter is provided with an exterior wall surface and a flange extending from the wall surface and disposed in spaced, substantially face-to-face relation with the wall surface;

said assembly comprising at least one removable bracket having a base portion adapted to slidably engage the wall surface, and releasable means extending from said base portion for disposition between the flange and the wall surface and slidably engaging the flange and retaining the bracket in predetermined positions on the primary unit;
and means coacting with the bracket base portion for connecting the secondary unit thereto.

The combination of a primary unit having an exterior wall surface provided with a flange extending therefrom and disposed in spaced, substantially face-to-face relation with the exterior wall surface, a secondary unit having a surface thereof outwardly spaced from the exterior surface of the primary unit, and an assembly removably attaching the secondary unit to the primary unit;

said assembly comprising a removable bracket slidably mounted on the flange of the primary unit, said bracket including a base portion engaging the exterior wall surface of the primary unit, at least one first extension extending laterally from the base portion and being slidably disposed between the exterior wall surface and the flange of said primary unit, and a second extension offset from said first extension and disposed outwardly from but in slidable contact with the flange, said extensions coacting to resiliently grip the flange therebetween and retain said bracket in a predetermined position with respect to said flange;
and adjustable means coacting with said bracket base portion for connecting said secondary unit thereto.
