TITLE: EXTENDABLE RACK
I. BACKGROUND 4F THE INVENTION
1. Field of the Invention The present invention relates in general to storage racks for hanging a plurality of cantilever supports and, more particularly, to an extendable rack.
I. BACKGROUND 4F THE INVENTION
1. Field of the Invention The present invention relates in general to storage racks for hanging a plurality of cantilever supports and, more particularly, to an extendable rack.
2. Description of the Prior Art Racks particularly designed to fit inside wardrobes andlor wardrobe cabinets, or for wall mounting are well known. The consumer satisfaction depends upon several factors including reliability, easy access and minimal space required.
Attempts have been made in the past to develop an improved rack. For example, United States Patent No. 6,152,312, dated November 28, 2000 and granted to Nava et al. for a " SUSPENDING SYSTEM FOR VAR.dOUS TYPES OF HANGING
SUPPORTS, IN PARTICULAR DESIGNED TO FIT WARDROBES " describes a System structurally formed by three components, l. e., a section bar, a fastener and a bracket. The section bar comprises a front portion suitable for receiving various kinds of cantilever supports and a rear portion suitable for being assembled on the fastener. The latter is mounted and fastened to a carrier bracket. This suspending system is considered to have several disadvantages. First, the suspending system is cumbersome due to the overall width of the fastener and the carrier bracket.
Second, Nava et al. suspending system requires special molds for manufacturing the fastener and the carrier bracket. As a result the total cost of the hanging system appears to be relatively high. United States Patent No. 4,569,450, dated February 11'~ 1986 and granted to Dillingham fox a "NECKTIE STORAGE WITH FOLDING
HANGER MEMBERS" describes an apparel support device particularly adapted for hanging a plurality of neckties. The apparel support device comprises an elongated base member having a longitudinal channel defined by opposed side walls and elongated parallel opposed grooves formed in the side walls. A plurality of hanger members is used. Each hanger member has a shank portion and an integral crank end portion connected to a link at spaced apart intervals on the link.
The device comprises as well an elongated channel shaped hanger support having a web portion and spaced apart parallel flanges connected to the web portion and supported at their distal end in the grooves. Crank supports axe provided on the parallel side flanges for supporting aad retaining the hanger members.
Dillingham device has shortcomings. It is complicated. It uses numerous components and does not provide a structural rigidity, required by this type of devices.
II. SUMMARY OF THE II~TVEIWTION
In view of the above considerations based on the identified prior art, there is a need to address rack design concerns and, consequently, to develop a rack that eliminates or, at least, alleviates the foregoing disadvantages and shortcomings.

4 III. DESCRIPTION OF THE PREFFERED EMBODIMENTS
An extendable rack 100, as shown in Fig. 1, comprises essentially an elongated horizontal body 200.
It is to be agreed, that terms such as "horizontal", "top", "bottom", "outwardly", "upwardly" and "downwardly" are conventionally used in the present description with reference to the normal position in which extendable rack 100 would be used.
In general, (see Figs. 2 and 2') extendable rack 100 has its elongated horizontal body 200 provided, in a first side 202, with a longitudinal channel 204. The latter is adapted for retaining one or more cantilever supports 300. Elongated horizontal body 200 is provided in a second side 208, usually opposed to first side 202, with a longitudinal passage 210. The latter is adapted for locating almost entirely a slide 400.
As can be seen in a phantom representation in Fig.2', slide 400 is of ball bearing drawer type and comprises an outer cage 402 and an inner cage 404 between which an upper row of balls 406 and a lower row of balls 408 are interposed. Outer cage 402 is firmly attached with first bolts or like 410 to elongated horizontal body 200, while inner cage 404 is firmly attached with second bolts or like 412 to a fixed panel (not shown). Thus, elongated horizontal body 200 is suitable for being glidingly assembled on slide 400 and can be extended far easy access to cantilever supports 300.
Referring now in detail to Figs. 2 and 2', in a first embodiment, elongated horizontal body 200 has longitudinal channel 204, C-shaped in cross section, with a perimeter defined by a standing segment 212 extending, at the top, into a downwardly curved segment 214 and, at the bottom, into an upwardly curved segment 216. Opposing niches 218 are formed. Each opposing niche 218 is adapted to capture a flange 302 of cantilever support 300.
Longitudinal channel 204 extends along elongated horizontal body 200.
Elongated horizontal body 200 has longitudinal passage 210, U-shaped in cross section, with a length commensurate with elongated horizontal body 200.
Longitudinal passage 210 has one upright segment 220 extending at the top and at the bottom into horizontal segments 222 and 224, Joints farmed between upright segment 220 and horizontal segments 222 and 224 are rounded. A first horizontal dimension L1 of longitudinal passage 210 is lesser than a second horizontal dimension L2 of a mounted slide 400. Thus, slide 400 extends laterally beyond longitudinal passage 210.
A movement of elongated horizontal body 200, with respect to a part of slide 400, which is attached to a fixed panel, is therefore possible.
Each horizontal segment 222 and 224 continues, at each outside extremity, with vertical segments 226 and 228, respectively opposed, which further continues with a curved segment 230 and 232, to finally merge with downwardly and upwardly projecting segments 214 and 216.
As a result, longitudinal cavities 234 and 236 having lengths commensurate with the lengths of longitudinal channel 204 and longitudinal passage 210 are formed.
Conveniently, a finger-pull 240 is attached to a front extremity 238 of elongated horizontal body 200, while a cap 242 is attached to a back extremity 244 of the same.
Finger-pull 240 and cap 242 comprise upper and lower projections 246 and 248 press fitted into longitudinal cavities 234 and 236. Front and back extremities 238 and 244 are closed by finger-pull 240 and by cap 242. Finger-pull 240 is used to drive elongated horizontal body 200 outwardly and inwardly.
A wall 254, formed between standing segment 212 and upright segment 220, contains, at each extremity, holes 256 located midway between the horizontal segments 222 and 224.
In a second embodiment, (see Fig. 3), an elongated horizontal body 260 has a central longitudinal wall 262. Central longitudinal wall 262, close to its top, extends outwardly and upwardly and forms a longitudinal top recess 264. At the bottom, central longitudinal wall 262, close to its bottom, extends outwardly and downwardly forming a longitudinal bottom recess 266. The purpose of longitudinal tap and bottom recesses 2b4 and 266 is to retain opposite flanges 304.
The remaining features of elongated horizontal body 260 are essentially similar with those described in elongated horizontal body 200.
1n a third embodiment, (see Fig. 4), an elongated horizontal body 268 has a central longitudinal wall 270. The latter extends, from midway of its height, outwardly, then upwardly and downwardly forming longitudinal top and bottom recesses 272 and 274, respectively. The purpose of longitudinal top and bottom recesses 272 and 274 is to retain opposite flanges 306.
The remaining features of elongated horizontal body 2b8 are essentially similar with those described in elongated horizontal body 200.
Elongated horizontal bodies 200, 260 and 268 are advantageously formed by an extrusion process. Aluminum, plastic and wood composite are usually used.
Since slider 400 is of a conventional and known design, mass-produced in different sizes, a fiuther explanation of the same appears to be unnecessary. For example, precision ball bearing drawer slides are sold under the trademark AccurideTM
by Accuride, Santa Fe Springs, California Cantilever supports 300 are designed in various shapes to accommodate different items, such as neckties, belts, trays etc.

As required, detailed embodiments of the present invention are disclosed herein;
however, it is to be understood that the disclpsed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, specific structural and functional details disclosed therein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure.
An extendable rack 100, as shown in Fig. 1, comprises essentially an elongated horizontal body 200.
It is to be agreed, that terms such as "horizontal", "top", "bottom", "outwardly", "upwardly" and "downwardly" are conventionally used in the present description with reference to the normal position in which extendable rack 100 would be used.
In general, (see Figs. 2 and 2') extendable rack 100 has its elongated horizontal body 200 provided, in a first side 202, with a longitudinal channel 204. The latter is adapted for retaining one or more cantilever supports 300. Elongated horizontal body 200 is provided in a second side 208, usually opposed to first side 202, with a longitudinal passage 210. The latter is adapted for locating almost entirely a slide 400.
As can be seen in a phantom representation in Fig.2', slide 400 is of ball bearing drawer type and comprises an outer cage 402 and an inner cage 404 between which an upper row of balls 406 and a lower row of balls 408 are interposed. Outer cage 402 is firmly attached with first bolts or like 410 to elongated horizontal body 200, while inner cage 404 is firmly attached with second bolts or like 412 to a fixed panel (not shown). Thus, elongated horizontal body 200 is suitable for being glidingly assembled on slide 400 and can be extended far easy access to cantilever supports 300.
Referring now in detail to Figs. 2 and 2', in a first embodiment, elongated horizontal body 200 has longitudinal channel 204, C-shaped in cross section, with a perimeter defined by a standing segment 212 extending, at the top, into a downwardly curved segment 214 and, at the bottom, into an upwardly curved segment 216. Opposing niches 218 are formed. Each opposing niche 218 is adapted to capture a flange 302 of cantilever support 300.
Longitudinal channel 204 extends along elongated horizontal body 200.
Elongated horizontal body 200 has longitudinal passage 210, U-shaped in cross section, with a length commensurate with elongated horizontal body 200.
Longitudinal passage 210 has one upright segment 220 extending at the top and at the bottom into horizontal segments 222 and 224, Joints farmed between upright segment 220 and horizontal segments 222 and 224 are rounded. A first horizontal dimension L1 of longitudinal passage 210 is lesser than a second horizontal dimension L2 of a mounted slide 400. Thus, slide 400 extends laterally beyond longitudinal passage 210.
A movement of elongated horizontal body 200, with respect to a part of slide 400, which is attached to a fixed panel, is therefore possible.
Each horizontal segment 222 and 224 continues, at each outside extremity, with vertical segments 226 and 228, respectively opposed, which further continues with a curved segment 230 and 232, to finally merge with downwardly and upwardly projecting segments 214 and 216.
As a result, longitudinal cavities 234 and 236 having lengths commensurate with the lengths of longitudinal channel 204 and longitudinal passage 210 are formed.
Conveniently, a finger-pull 240 is attached to a front extremity 238 of elongated horizontal body 200, while a cap 242 is attached to a back extremity 244 of the same.
Finger-pull 240 and cap 242 comprise upper and lower projections 246 and 248 press fitted into longitudinal cavities 234 and 236. Front and back extremities 238 and 244 are closed by finger-pull 240 and by cap 242. Finger-pull 240 is used to drive elongated horizontal body 200 outwardly and inwardly.
A wall 254, formed between standing segment 212 and upright segment 220, contains, at each extremity, holes 256 located midway between the horizontal segments 222 and 224.
In a second embodiment, (see Fig. 3), an elongated horizontal body 260 has a central longitudinal wall 262. Central longitudinal wall 262, close to its top, extends outwardly and upwardly and forms a longitudinal top recess 264. At the bottom, central longitudinal wall 262, close to its bottom, extends outwardly and downwardly forming a longitudinal bottom recess 266. The purpose of longitudinal tap and bottom recesses 2b4 and 266 is to retain opposite flanges 304.
The remaining features of elongated horizontal body 260 are essentially similar with those described in elongated horizontal body 200.
1n a third embodiment, (see Fig. 4), an elongated horizontal body 268 has a central longitudinal wall 270. The latter extends, from midway of its height, outwardly, then upwardly and downwardly forming longitudinal top and bottom recesses 272 and 274, respectively. The purpose of longitudinal top and bottom recesses 272 and 274 is to retain opposite flanges 306.
The remaining features of elongated horizontal body 2b8 are essentially similar with those described in elongated horizontal body 200.
Elongated horizontal bodies 200, 260 and 268 are advantageously formed by an extrusion process. Aluminum, plastic and wood composite are usually used.
Since slider 400 is of a conventional and known design, mass-produced in different sizes, a fiuther explanation of the same appears to be unnecessary. For example, precision ball bearing drawer slides are sold under the trademark AccurideTM
by Accuride, Santa Fe Springs, California Cantilever supports 300 are designed in various shapes to accommodate different items, such as neckties, belts, trays etc.
