Abstract
An apparatus for securing telescoping sliding panels, which are essentially oriented in parallel, vertical planes, against movement perpendicular to their sliding directions, includes a track, parallel first and second carriages which retain the lower edge of each panel and ride along the track, a lip projecting from the first carriage having an upturned free end, a lip projecting from the second carriage, having a downturned free end which extends between the first carriage and the upturned end of its lip. The carriage for each panel preferably includes a body portion which is tubular and has wheels mounted beneath it and gripping members projecting from the top of it for holding a vinyl channel which receives the lower edge of the panel. The track has an upper surface with channels recessed into it for guiding the carriages. An edge of the track is turned upward at a right angle to form a wall for retaining the carriages. The wall is provided with a lip described above. A threshold member is optionally provided which attaches to the wall and a channel of the track, to provide a horizontal surface which a person can step on without damaging it. The threshold member may have a lip described above. A method for retaining the panels includes the step of placing the downward portion of the second lip between the upward portion of the first lip and the first carriage.References Cited

- 1. An apparatus for securing telescoping sliding panels, which are essentially oriented in parallel, vertical planes, against movement perpendicular to their sliding directions, wherein each panel has a lower edge, comprising:track means,parallel first and second carriage means which retain the lower edge of each panel and ride along the track means,lip means projecting from at least one first carriage means having an upturned free end,lip means projecting from at least one second carriage means having a downturned free end which extends between the at least one first carriage means and the upturned end of its lip means.
- 15.15. A method of retaining sliding telescoping panels riding on first and second carriage means, the first carriage means having at least one first lip with an upturned edge and the second carriage means having at least one second lip with a downturned edge, within channels along track means against movement relative to each other perpendicular to their geometric planes, comprising the step of:placing the downward portion of the at least one second lip between the upward portion of the least one first lip and the first carriage means.
