Abstract
Abstract A drawer glide assembly has a positively actuated locking mechanism which prevents accidental disengagement of the drawer (10) from the cabinet rails (12). The locking mechanism includes a lever arm (20) pivotally mounted on a bracket (18) on the drawer rail (11). The lever arm slides along the lower wall (14) of the cabinet rail (12) and is received within a slot (25) in the rail (12). The locking mechanism includes a handle (32) which pivots upwardly to disengage the stop member (30) from the slot (25), allowing easy removal of the drawer (10) from the cabinet (8). Additionally, the rails are provided with an offset guide track in which rollers (21), (22) are guided in order to facilitate movement of the drawer (10). The use of such an offset guide track permits the rails (11), (12) to be mounted to the drawer (10) or cabinet (8) by means of pan-head screws (50). In this way, the screws (50) do not have to be recessed into the cabinet (8) or drawer (10) and do not interfere with the operation of the guide assembly.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
211 words
A drawer glide assembly comprising: first and second longitudinally extending channel members, each of said channel members including a central web and a pair of spaced parallel side webs perpendicular to the plane of said central web, said channel members being disposed in a vertical arrangement with the lower side web of said first channel member adjacent the upper side web of said second channel member and the central webs in a laterally spaced parallel relationship; a mounting bracket secured to and extending from each of said channel members at an end thereof; a roller rotatably mounted on each mounting bracket and extending into the guide channel defined by said side webs of an opposing track member; a lever arm pivotably mounted on said mounting bracket secured to said first channel member; a stop member disposed on the lever arm and in sliding engagement with the lower side web of said second channel member; and stop means on the lower side web of said second channel member for engaging said stop member so as to limit relative longitudinal displacement of said channel members; wherein said stop member pivots downwardly with respect to said lower side web of said second channel member upon alignment of the stop member and said stop means.
Claim 2
Dependent Claim

A drawer glide assembly comprising: first and second longitudinally extending channel members, each of said channel members including a central web and a pair of spaced parallel side webs perpendicular to the plane of said central web, said channel members being disposed in a vertical arrangement with the lower side web of said first channel member adjacent the upper side web of said second channel member and the central webs in a laterally spaced parallel relationship; a mounting bracket secured to and extending from each of said channel members at an end thereof; a roller rotatably mounted on each mounting bracket and extending into the guide channel defined by said side webs of an opposing track member; a lever arm pivotably mounted on said mounting bracket secured to said first channel member; a stop member disposed on the lever arm and in sliding engagement with the lower side web of said second channel member; and stop means on the lower side web of said second channel member for engaging said stop member so as to limit relative longitudinal displacement of said channel members; wherein said stop member pivots downwardly with respect to said lower side web of said second channel member upon alignment of the stop member and said stop means.
Claim 3
Dependent Claim
30 words
The drawer glide assembly of claim 1 wherein said stop member includes a cam on a lower surface thereof and said stop means is an opening for receiving said cam.
Claim 4
Dependent Claim
22 words
The drawer glide assembly of claim 2 wherein said lever arm is pivotally mounted forward of said roller secured to the bracket.
Claim 5
Dependent Claim
39 words
The drawer glide assembly of claim 3 wherein the lever arm extends forwardly from the mounting bracket to project past the front edge of the second channel member when said stop member is in engagement with said stop means.
Claim 6
Dependent Claim
35 words
The drawer glide assembly of claim 1 wherein said mounting bracket includes a flange which is received in a depression formed in the back surface of said central web in a generally overlapping relationship therewith.
Claim 7
Dependent Claim
37 words
The drawer glide assembly of claim 1 wherein said side webs are transversely spaced from the elongate edges of said central web to define a guide channel which is spaced from the plane of said central web.
Claim 8
Dependent Claim
21 words
The drawer glide assembly of claim 5 wherein said flange is secured to said channel member by at least one rivet.
Claim 9
Dependent Claim
49 words
The drawer glide assembly of claim 6 wherein said cabinet and drawer channels are secured to a respective cabinet and drawer by screws, said screws including a head portion having a thickness which is less than the spacing of the side webs from the plane of said central web.
Claim 10
Dependent Claim
13 words
The drawer glide assembly of claim 1 wherein said lever arm is plastic.
Claim 11
Dependent Claim
21 words
The drawer glide assembly of claim 1 wherein said lever arm is pivotably mounted on a pin carried on said bracket.
Claim 12
Dependent Claim
39 words
The drawer glide assembly of claim 1 wherein the relative positions of said cam and said pin tend to cause a downwards pivoting of said lever arm with respect to said lower side web of said second channel member.
