Description
- This is a divisional application of U.S. patent application Ser. No. 10/554,177, filed Oct. 21, 2005, which was the National Stage of International Application No. PCT/US2004/012555, filed Apr. 23, 2004, which claims the benefit of U.S. Provisional Application No. 60/464,699, filed on Apr. 23, 2003.
- The present invention relates to a drawer assembly for a cabinet. More particularly, the invention relates to a fire resistant stackable vertical file cabinet having fully extendable drawers that reduce the amount of binding and scraping that occurs within the cabinet, and which is easy to install.
- Vertical file cabinets typically include a plurality of individual cabinet housings which open at the front so as to receive a plurality of file drawers therein in a vertically stacked arrangement. Such cabinets are well known and typically use fasteners such as screws or other connection methods to assemble the individual cabinet housings to one another to form a vertical cabinet assembly.
- However, existing vertical file cabinets have a number of drawbacks and deficiencies. For instance, the use of screws or similar fasteners to secure each file cabinet to one another to form a vertical file cabinet can be difficult and time consuming. In addition, the use of screws or similar fasteners makes it difficult and inconvenient to rearrange or customize the configuration of the cabinets to suit the needs of a user.
- Existing vertical file cabinets also include drawers that are slidably positioned within the drawer housing by guide tracks that run on rollers or ball bearings. Also, the drawer assembly itself is made up of a number of parts that are assembled through the use of various tools and fasteners. The use of rollers and ball bearings and the need to use tools and fasteners to assemble the drawer assembly increases manufacturing time and cost.
- Additionally, locking mechanisms used on file cabinets have a tendency to lose their ability to secure the file cabinet when exposed to fire. In particular, exposing the lock to increased temperatures causes the lock components to either melt or lose their structural integrity so that the cabinet drawer may be opened without regard to the locking mechanism.
- Accordingly, there exists a need for a drawer assembly that minimizes the use of tools and fasteners to reduce manufacturing time and cost. The present invention fills these needs as well as other needs.
- In order to overcome the above stated problems and limitations there is provided a drawer assembly adapted to be selectively received within a housing. The drawer assembly comprises a drawer frame, a front drawer assembly, first and second slide members, and first and second clips. The drawer frame includes a front section, first and second side sections coupled with the front section, and a back section coupled with the first and second side sections. The first side section has a first drawer track protruding outwardly therefrom, and the second side section has a second drawer track protruding outwardly therefrom, wherein each of the first and second drawer tracks have an elongated slot defined therein. The front drawer assembly is coupled with the front section. The first slide member includes a first slide tab having a first lock slot defined therein, and the second slide member includes a second slide tab having a second lock slot defined therein. The first clip includes a first locking tab, and the second clip includes a second locking tab. The first slide tab is positioned within the elongated slot defined in the first drawer track, wherein the first clip is positioned between the first slide tab and the first drawer track. The first locking tab is positioned within the first lock slot so that the first slide member is slidably coupled with the first side section of the drawer frame. The second slide tab is positioned within the elongated slot defined in the second drawer track, wherein the second clip is positioned between the second slide tab and the second drawer track. The second locking tab is positioned within the second lock slot so that the second first slide member is slidably coupled with the second side section of the drawer frame.
- In addition, at least one of the first and second clips may include a flange member and an engaging portion, wherein the locking tab protrudes from the engaging portion. Further, the flange member may be positioned perpendicular relative to the engaging portion, and a brace may extend between the flange member and the engaging portion. Furthermore, at least one of the first and second slide members may include an upper surface having a slot defined therein, wherein an upper extrusion is positioned within the slot defined in the upper surface so that the upper extrusion is in sliding contact with the respective drawer track. Also, at least one of the first and second slide members may include a lower surface having a slot defined therein, wherein a lower extrusion is positioned within the slot defined in the lower surface so that the lower extrusion is in sliding contact with the respective drawer track.
- Additional objects, advantages and novel features of the present invention will be set forth in part in the description which follows, and will in part become apparent to those in the practice of the invention, when considered with the attached figures.
