Abstract
A linear actuator extension assembly having a base housing, a driving member and a driven member having a housing. The driving member has a driving surface and a threaded lead screw disposed within the base housing. The driving surface is rotated about a first axis to actuate the threaded lead screw, thereby rotating the threaded lead screw about a second axis substantially orthogonal to the first axis. The rotation of the threaded lead screw translates the driven member housing relative to the base housing.
Claims18
A barrier assembly, comprising:
- a barrier having a frame;
- and
- at least one linear actuator extension attached to the frame, comprising:
- a worm drive having a worm gear and a driving surface, and a given length;
- a driving member having a threaded lead screw;
- a driven member having a housing;
- a base housing having a given width, the base housing disposed within the frame, wherein the length of the worm drive fits within the width of the base housing;
- and
- an aperture disposed within the base housing,
- wherein the worm drive and the driving member are enclosed within the aperture of the base housing, such that rotating the driving surface of the worm drive about a first axis within the base housing causes the worm gear to rotate teeth on the threaded lead screw to rotate the threaded lead screw about a second axis substantially orthogonal to the first axis, and wherein the rotation of the threaded lead screw translates the housing of the driven member along the second axis within the base housing.
A barrier assembly, comprising:
- a barrier having a frame;
- and
- at least one linear actuator extension attached to the frame, comprising:
- a worm drive having a worm gear and a driving surface, and a given length;
- a driving member having a threaded lead screw;
- a driven member having a housing;
- a base housing having a given width, the base housing disposed within the frame, wherein the length of the worm drive fits within the width of the base housing;
- and
- an aperture defined in the base housing;
- wherein the worm drive and the driving member are enclosed within the aperture of the base housing, such that rotating the driving surface of the worm drive about a first axis within the base housing causes the worm gear to rotate teeth on the threaded lead screw to rotate the threaded lead screw about a second axis, and wherein the rotation of the threaded lead screw translates the housing of the driven member along the second axis within and relative to the base housing.
A barrier assembly, comprising:
- a barrier having a frame;
- and
- at least one linear actuator extension attached to the frame, comprising:
- a worm drive having a worm gear and a driving surface, and a given length;
- a driving member having a threaded lead screw defining a first central axis;
- and
- a driven member having a housing and a threaded portion that engages the threaded lead screw,
- wherein the worm drive and a portion of the driving member are disposed within an aperture disposed in a base housing having a given width that is enclosed and disposed within the frame, wherein the length of the worm drive fits within the width of the base housing, such that a rotation of the driving surface of the worm drive within the base housing about a second central axis drives a rotation of the threaded lead screw about the first central axis to linearly translate the portion of the driven member along the first central axis within the base housing.
