## Background
TECHNICAL FIELD
This invention relates generally to hardware. More specifically, the invention is directed to drawer glides.
BACKGROUND OF THE INVENTION
Many drawer glides do not allow for the efficient opening and closing of a drawer. For example, some glides are “sloppy” in that they allow the drawer to move laterally within a cabinet. This often results in racking during opening and closing. There are also glides that do not provide enough drag on the drawer during opening, which can result in cascading. Moreover, some glides are noisy during operation. With respect to ready-to-assemble (“RTA”) furniture, some glides are often difficult to assemble.
BRIEF SUMMARY OF THE INVENTION
This invention overcomes the above-identified issues by providing a drawer glide that allows for the efficient opening and closing of a drawer. For example, the drawer glide has, among other things, a cabinet rail that includes a glide member and a wheel housing. The drawer glide further includes a drawer rail having a wheel and a glide lip. In operation, the cabinet rail is positioned on a cabinet and the drawer rail is positioned on a drawer. When the drawer is opened, the glide lip travels along the glide member and the wheel travels along the wheel housing. The drawer glide prevents slop, eliminates racking, increases drag and reduces noise. Further, the drawer glide is relatively easy to install on an article, such as RTA furniture.

As shown in FIG. 5, the drawer rail 94 includes one or more openings 138 through which fasteners can extend for attachment to the drawer. The drawer rail 94 can be made from a variety of suitable materials. For example, the drawer rail body 100 and the wheel pin 124 can be made of metal and the wheel 112 can be made of plastic for, among other things, strength, durability and cost.
Referring to FIGS. 2-4, 6, 7 and 8-10, the assembly and operation of the drawer glide 10 will be described. For example, the drawer glide 10 will described in relation to RTA furniture. To install a drawer in a cabinet, the consumer or user positions a cabinet rail 12 on an interior surface of the cabinet in which the cabinet rail front end 14 is positioned adjacent to the front of the cabinet and the cabinet rail back end 16 is positioned adjacent to the back of the cabinet. The cabinet rail exterior surface 26 is positioned adjacent to the cabinet. Because the cabinet rail 12 is universal, as described above, the cabinet rail 12 can be mounted on either the right side or the left side of the cabinet. A drawer rail 94 is positioned on an exterior side surface of the drawer in which the drawer rail front end 96 is positioned adjacent to the front of the drawer and the drawer rail back end 98 is positioned adjacent to the back of the drawer. The drawer rail 94 is configured for positioning on either the right side or the left side of the drawer. A right side drawer rail 94 is shown in FIGS. 8-10. A left side drawer rail includes all of the elements as described above with respect to the right side drawer rail 94.
When the cabinet rail 12 and the drawer rail 94 are positioned, the drawer is installed in the cabinet by inserting the wheel 112 of the drawer rail 94 in the wheel housing 72 of the cabinet rail 12. In this regard, the housing engagement surface 114 of the wheel 112 engages one or more of the surfaces 78, 80, 82, 84, 86 and 88 of the housing 72. The glide member first surface 32 of the glide member 30 engages the glide member surface 132 of the glide lip 130 (the second glide surface 34 would be so engaged on a left side drawer rail), the glide member interior surface 40 engages the outer glide surface 134 and the glide member exterior surface 42 engages the inner glide surface 136. The wheel 112 can be seated in the wheel pocket 90.
The drawer glide 10 allows for the efficient opening and closing of the drawer. During operation, the glide lip 130 travels along the glide member 30 and the wheel 112 travels along the wheel housing 72. This prevents slop, eliminates racking, increases drag and reduces noise during the opening and closing of the drawer. Further, the drawer glide 10 is relatively easy to install on an article, such as RTA furniture.
