Abstract
Abstract This invention pertains to hardware for installing framed door panels in a doorway to provide a sliding door installation. Door panels are framed with rails and stiles that are interconnected at the door corners by identical brackets. The brackets at the top corners of the doors are used to carry roller wheels that rest on upper trackways of the doorway and the brackets at the bottom corners of the doors are used to carry guides that guide the doors over the trackways of a threshold of the doorway.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
210 words
A guide adapted to be assembled with a panel or the like and utilized to guide the panel or the like in a predetermined path over an elongated trackway having a two sided trackway slot with a longitudinal slot lip, the guide comprising: a guide element having a base portion two laterally spaced guide legs arranged in parallel spaced relation to each other that extend downwardly from said base portion; said legs being of a width less than the width of the trackway slot whereby said legs may be inserted into said trackway slot so that said legs are spaced longitudenally within said trackway slot; a latch element rotatabLy mounted between said legs so as to be rotatable about a rotation axis along which said legs are laterally spaced; said latch element including vertically spaced apart lips forming a channel therebetween on one side of said latch element; said latch element being rotatable between said legs from a first rotational position permitting insertion of said legs into said trackway slot to a second rotational position wherein said lips encompass said trackway lip in said channel of said latch element to operatively engage said guide to said trackway and to prohibit inadvertent removal of said guide legs from said trackway slot.

Claim 3
Dependent Claim
31 words
The guide set forth in claim 1 wherein said legs and said latch element include means for releaseably locking said latch element in either said first or said second rotational positions.
Claim 4
Dependent Claim
52 words
The guide set forth in claim 2 wherein said means for releaseably locking said latch element in either said first or second rotational positions includes lateral projections on said latch element which are releaseably engageable with recesses formed on said legs to releaseably lock said latch element in said first rotational position.
Claim 5
Dependent Claim
55 words
The guide set forth in claim 2 wherein said means for releaseably locking said latch element in either said first or second rotational positions includes lateral projections on said latch element that are positionable against the sides of the legs facing said trackway lip to releaseably lock said latch element in said second rotational position.
Claim 6
Dependent Claim
42 words
The guide set forth in claim 1 wherein the upper surface of said latch element is angled to permit rotation of said latch element to said second rotational position wherein said upper surface abuts the said base portion of said guide element.
Claim 7
Dependent Claim
26 words
The guide set forth in claim 1 wherein said legs include a respective slot receiving a respective end of a shaft portion of said latch element.
Claim 8
Dependent Claim
35 words
The guide set forth in claim 1 wherein the particular latch element lip nearest said base portion of said guide element is shaped to define shoulder surfaces at an upper surface of said latch element.
Claim 9
Dependent Claim
63 words
The guide set forth in claim 1 wherein the particular latch element lip nearest said base portion of said guide element is disposed so that upon insertion of said guide legs into said trackway slot said trackway lip is operable upon the lower portion of said particular latch element lip to rotate said latch element from said first to said second rotational position.
