Abstract
A first adjustable cabin rail guide is moveably attached to a structural member of an elevator cabin. A second adjustable cabin rail guide is similarly moveably attached to a structural member of an elevator cabin. The first and second adjustable cabin rail guides cooperate together to reduce sound and increase operational efficiency. A piece of textile or similar material is attached to a tube forming the friction portion of the guide. The use of textile thereby reduces the sound of the travel upon the rail associated with the inner portion of the elevator cylinder as the cabin transits therein.
Claims12
A pneumatic vacuum elevator guide system comprising:
- a pneumatic vacuum elevator cabin having
- a support member attached thereto;
- and
- a first rail guide moveably mounted with respect to the pneumatic vacuum elevator cabin on the support member;
- wherein the first rail guide further comprises:
- a tube having a first external surface;
- a first textile material attached to the first external surface of the tube such that the tube directly impacts a first rail through the first textile material;
- wherein the first rail is attached to a pneumatic vacuum elevator thoroughfare within which the pneumatic vacuum elevator cabin moves;
- a sheet movably attached to the support member and such that the tube is movably attached to the sheet;
- wherein the movable attachment of the sheet to the support member has a different degree of motion relative to the pneumatic vacuum elevator cabin compared to the movable attachment of the tube to the sheet;
- a friction adjuster attaching the sheet to the tube whereby the movable attachment of the tube to the sheet allows for a variable selective friction force to the rail through the first textile material;
- wherein the friction adjuster further comprises:
- an adjustable spring assembly;
- a fastener inserted within a hole in the sheet and attached therethrough to a threaded rivet which is attached to a hole in the tube;
- and
- having a spring between the threaded rivet and the fastener such that the fastener passes through spring allowing for selective variable friction force applied to the first rail through the first textile material.

An elevator rail guide assembly comprising:
- a first rail guide moveably attached to
- an elevator cabin;
- wherein the first rail guide comprises
- a textile material fixedly attached to an external surface of a textile mount wherein the textile mount is formed as a tube;
- whereby the tube directly impacts a rail within an elevator thoroughfare through the textile material;
- a support member integral with the elevator cabin whereby the first rail guide further comprises a sheet that is movably attached to the support member;
- whereby the tube is movably attached to the sheet;
- and wherein the moveable attachment of the sheet with respect to the support member has distinct degrees of motion relative to the elevator cabin compared to the moveable attachment of the tube with respect to the sheet;
- wherein the attachment of the tube to the sheet is through a friction adjuster having selective variable friction force applied to the rail;
- wherein the friction adjuster further comprises a fastener adjustably attached to a threaded rivet between the tube and the sheet using a spring;
- whereby the tube is movably attached to the sheet through an adjustment of the fastener thereby providing selective variable friction force to the rail.

A pneumatic vacuum elevator system comprising:
- a pneumatic vacuum elevator cylinder having a cabin inserted therein;
- a first adjustable rail guide comprising:
- a rigid member moveably attached to the cabin;
- a tube that has a textile material attached thereto, such that the tube is adjustably attached with respect to the rigid member using a friction adjuster attached to the rigid member and to the tube;
- the friction adjuster has selective variable friction applied to a rail;
- the first adjustable rail guide is moveably attached with respect to the cabin and in physical contact with the rail attached to the pneumatic vacuum elevator cylinder such that the tube directly contacts the rail through the textile material;
- wherein the adjustable attachment of the tube to the rigid member has a different degree of motion relative to the cabin compared to the moveable attachment of the rigid member to the cabin;
- and
- wherein the friction adjuster further comprises a fastener and a hole rivet attached together between the rigid member and the textile material mount through a hole in the rigid member and a corresponding hole in the textile material mount with a spring loaded therebetween.
