Filed:

Feb 3, 2012

Appl. No.:

13/365970

Inventors:

David Younce - Black Diamond WA, US
Geoffrey M. Pate - Maple Valley WA, US
Brian G. DeNault - Seattle WA, US
Steven A. Carlsen - Bothell WA, US

Assignee:

Hy-Security Gate, Inc. - Kent WA

International Classification:

E05F 15/14
E06B 5/00
H02K 7/116

US Classification:

49359, 310 83, 49358, 49506

Abstract:

A linear gate drive assembly with a drive rail connectable to a gate panel. A linear drive portion having a toothed drive surface is coupled to a first drive surface of the drive rail and has teeth thereon with a first rolling tooth profile. A drive wheel is attached to one drive motor and engages the first drive surface to impart an axial drive force on the drive rail. Another drive wheel is attached to another drive motor and engages the second drive surface. The second drive wheel has teeth that mate with the first teeth and that define another rolling tooth profile corresponding to the first rolling tooth profile. Rotation of the second drive wheel imparts axial and normal forces via a rolling teeth interface for moving the drive rail and the gate panel.

Abstract:

A linear gate drive assembly with a drive rail connectable to a gate panel. The drive rail has a first drive surface. A linear drive portion is coupled to the first drive surface and has teeth thereon with a first rolling tooth profile. The linear drive portion defines a toothed second drive surface. Dive motors are pivotally coupled to a support structure. A first drive wheel is attached to one drive motor and engages the first drive surface to impart an axial drive force on the drive rail. A second drive wheel is attached to another drive motor and engages the second drive surface. The second drive wheel has second teeth that mate with the first teeth and that define a second rolling tooth profile that substantially corresponds to the first rolling tooth profile. Rotation of the second drive wheel imparts axial and normal forces via a rolling teeth interface the mating teeth for moving the drive rail and the gate panel.
