Abstract

Abstract The invention pertains to a gate of the type generally used in the supermarkets and similar establishments, comprising substantially the combination of at least a bracket including an electric motor driving a vertical shaft carrying a barrier consisting preferably of a U-shaped cross-bar, the said electric motor being operated through signals coming from a passage detecting system, characterized in that the free ends of the said barrier are pivotably and adjustably connected with supporting levers secured to the said vertical shaft, the axis of the said shaft being spaced from the vertical limiting plane of the passage by a distance which is at least equal to the thickness of the barrier of the gate, windows being provided in the bracket, thereby allowing a rotation of the said barrier of at least 90° from a position perpendicular to the said limiting plane to a position parallel with the latter and vice versa.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 106 words
A gate of the type generally used in supermarkets and similar establishments comprising: a generally vertical rotatable axle; vertically spaced supporting levers secured to and extending laterally of said axle, said levers having generally flat upper surfaces; a pair of cylindrical rods secured to each upper surface in spaced parallel relation; a U-shaped barrier having free ends and headed bolts pivotally connecting said free ends to said supporting levers to overlie said flat upper surfaces between said cylindrical rods; and spring means reacting against the heads of said bolts urging said free ends against said upper surfaces whereby said barrier may be rotated in either direction.
Claim 2
Dependent Claim 106 words
