Abstract

Abstract A gate assembly including a support structure, a gate carried by the support structure and movable with respect thereto, a gate control and a gate activator associated with the gate, the support structure including a plurality of frame members, the gate having one end thereof disposed adjacent to the support structure and extending outwardly therefrom, a pivot connecting a lower part of the gate to an adjacent lower portion of the support structure, the pivot including a rotatable shaft and shaft carrier, the gate control including a biasing mechanism associated with the gate, the gate activator including a power source mounted on the support structure, drive mechanism operatively connected to the power source, the drive mechanism including translating mechanism activatable by the power source, the translating mechanism being disposed for movement in a substantially horizontal plane, an arm member having one end pivotally connected to the translating mechanism, the arm member having its opposite end pivotally connected to the gate, the connection between the arm member and the gate being at a point on the gate adjacent the support structure and centrally located between the upper and lower edges of the gate, whereby the gate is movable about the pivot in a vertical plane by the gate activator.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 221 words
A gate assembly including support means, gate means carried by said support means and movable with respect thereto, gate control means and gate activating means associated with said gate means, said support means including a plurality of frame members, said gate means having one end thereof disposed adjacent to said support means and extending outwardly therefrom, pivot means connecting a lower part of said gate means to an adjacent lower portion of said support means, said pivot means including a rotatable shaft and shaft carrier means, said gate control means including biasing means associated with said gate means, said gate activating means including a power source mounted on said support means, drive means operatively connected to said power source, said drive means including translating means activatable by said power source, said translating means being disposed for movement in a substantially horizontal plane, an arm member having one end pivotally connected to said translating means, said arm member having its opposite end pivotally connected to said gate means, said connection between said arm member and said gate means being at a point on said gate means adjacent said support means and centrally located between said upper and lower edges of said gate means, whereby said gate means is movable about said pivot means in a vertical plane by said gate activating means.
Claim 2
Dependent Claim 221 words
A gate assembly including support means, gate means carried by said support means and movable with respect thereto, gate control means and gate activating means associated with said gate means, said support means including a plurality of frame members, said gate means having one end thereof disposed adjacent to said support means and extending outwardly therefrom, pivot means connecting a lower part of said gate means to an adjacent lower portion of said support means, said pivot means including a rotatable shaft and shaft carrier means, said gate control means including biasing means associated with said gate means, said gate activating means including a power source mounted on said support means, drive means operatively connected to said power source, said drive means including translating means activatable by said power source, said translating means being disposed for movement in a substantially horizontal plane, an arm member having one end pivotally connected to said translating means, said arm member having its opposite end pivotally connected to said gate means, said connection between said arm member and said gate means being at a point on said gate means adjacent said support means and centrally located between said upper and lower edges of said gate means, whereby said gate means is movable about said pivot means in a vertical plane by said gate activating means.
Claim 3
Dependent Claim 25 words

Claim 5
Dependent Claim 40 words
A gate assembly according to claim 1 wherein said arm member is pivotally connected to said gate means at a point from the horizontal center line of said gate means within about 10% of the height of said gate means.
Claim 6
Dependent Claim 15 words
A gate assembly according to claim 1 wherein said translating means includes flexible connecting means.
Claim 7
Dependent Claim 16 words
A gate assembly according to claim 5 wherein said flexible connecting means includes a continuous loop.
Claim 8
Dependent Claim 15 words
A gate assembly according to claim 5 wherein said flexible connecting means includes a chain.
Claim 9
Dependent Claim 14 words
A gate assembly according to claim 5 wherein said translating means includes a cable.
Claim 10
Dependent Claim 23 words
A gate assembly according to claim 1 wherein said pivotal connection between said arm member and said translating means is a releasable connection.
Claim 11
Dependent Claim 15 words
A gate assembly according to claim 1 wherein said power source includes an electric motor.
Claim 12
Dependent Claim 44 words
A gate assembly according to claim 1 wherein said biasing means includes at least one coil spring member extending between an upper part of said gate means adjacent to said support means and said support means at a point spaced from said pivot means.
Claim 13
Dependent Claim 24 words
A gate assembly according to claim 11 including fulcrum means disposed adjacent the end of the said spring member affixed to said support means.
