Abstract
Abstract A track and latch assembly for a slidable door is disclosed. The track and latch assembly is operative in combination with a slidable door of the type which is slidably supported adjacent the upper end thereof from a wall so that the door is slidable along the surface of the wall for movement between open and closed positions, but so that the door is slightly outwardly pivotable about an axis adjacent the upper end thereof for movement of the lower portion of the door outwardly slightly with respect to the wall. The track and latch assembly includes a track which is mounted in fixed relation with respect to the wall adjacent the lower end of the door and a latch assembly which is mounted on the door. The latch assembly and the track cooperate for guiding and positioning the lower end of the door so that when it is in either of the open or closed positions thereof, it is in snug engagement with the wall adjacent the lower end of the door, but so that when the door is in an intermediate position, the lower portion thereof is outwardly spaced from the wall to permit the door to slide freely. Accordingly, the door is firmly held so that it is maintained substantially rattle-free when it is in either of the open or closed positions but it is nevertheless easily slidable between said positions.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
200 words
A track and latch assembly for a slidable door, wherein the door is slidably supported adjacent a wall so that it is movable between an open position, wherein an opening in the wall is substantially unobstructed by the door, and a closed position wherein the opening is substantially obstructed by the door, the door being at least slightly pivotable about an axis adjacent the upper end thereof for movement of the lower end of the door outwardly slightly with respect to the wall, said track and lock assembly comprising: (a) latch means mounted on said door adjacent the lower end thereof; and (b) track means mounted in a fixed position with respect to said wall adjacent the lower end of said door, said latch means being received in said track means and cooperating therewith to guide and position said door so that when it is in one of said open or closed positions thereof, it is in snug engagement with said wall adjacent the lower end of said door but so that during movement of said door between said open and closed positions thereof, the portion of said door adjacent the lower end thereof is spaced outwardly from said wall.
Claim 2
Dependent Claim
200 words
A track and latch assembly for a slidable door, wherein the door is slidably supported adjacent a wall so that it is movable between an open position, wherein an opening in the wall is substantially unobstructed by the door, and a closed position wherein the opening is substantially obstructed by the door, the door being at least slightly pivotable about an axis adjacent the upper end thereof for movement of the lower end of the door outwardly slightly with respect to the wall, said track and lock assembly comprising: (a) latch means mounted on said door adjacent the lower end thereof; and (b) track means mounted in a fixed position with respect to said wall adjacent the lower end of said door, said latch means being received in said track means and cooperating therewith to guide and position said door so that when it is in one of said open or closed positions thereof, it is in snug engagement with said wall adjacent the lower end of said door but so that during movement of said door between said open and closed positions thereof, the portion of said door adjacent the lower end thereof is spaced outwardly from said wall.
Claim 3
Dependent Claim
39 words
In the track and latch assembly of claim 1, said track means cooperating to position said door so that it is in snug engagement with said wall when it is in either of said open or closed positions thereof.
Claim 4
Dependent Claim
46 words
In the track and latch assembly of claim 2, said latch means comprising: (a) a latch element; and (b) means mounting said latch element on said door so that it is vertically movable and so that it is downwardly biased and received in said track means.
Claim 5
Dependent Claim
110 words
In the track and latch assembly of claim 2, said track means comprising: (a) an elongated substantially straight main track portion mounted in substantially parallel spaced relation to said wall adjacent the lower end of said door; and (b) first and second track end portions, said first track end portion extending from one end of said track main portion toward said wall and cooperating with said latch means to position said door in the open position thereof, said second track end portion extending from the other end of said main track portion toward said wall and cooperating with said latch means to position said door in the closed position thereof.
Claim 6
Dependent Claim
81 words
In the track and latch assembly of claim 4, said first and second track end portions having upwardly facing inner surfaces which are upwardly inclined in directions generally toward said wall terminating in locking surfaces which face generally toward said wall, said latch element traveling over the respective inner surface during movement of said door to either of the open or closed positions thereof and passing downwardly adjacent the respective locking surface to retain said door in engagement with said wall.
Claim 7
Dependent Claim
86 words
In the track and latch assembly of claim 5, said locking surfaces intersecting with the respective inner surfaces to define locking edges of the respective track end portions, said latch element having a bevelled surface thereon which faces generally outwardly with respect to said door and downwardly, the respective locking edge camming against said bevelled surface to urge said door into snug engagement with said wall adjacent the lower end of said door when said door is in either of said open or closed positions thereof.
Claim 8
Dependent Claim
80 words
In the track and latch assembly of claim 5, each of said track end portions having a pair of spaced retainer arms which extend inwardly toward said wall and cooperate with the respective locking surface to define a substantially vertical slot, said latch element being received in the respective slot when said door is in either of the open or closed positions thereof, whereby said latch element cooperates with the respective retainer arms to prevent sliding movement of said door.
Claim 9
Dependent Claim
53 words
In the track and latch assembly of claim 5, said track main portion having an inner track surface, said latch element traveling over said main portion inner track surface when said latch element is positioned in said track main portion, said upwardly inclined inner surfaces extending from said track main portion inner surface.
Claim 10
Dependent Claim
18 words
In the track and latch assembly of claim 8, said track end portions extending arcuately toward said wall.
