Abstract
An extendable rack is adapted for retaining one or more cantilever support(s) and is also adapted for attaching to a panel via a slide. The extendable rack comprises an elongated body including, at one side, a longitudinal channel for retaining one or more cantilever support(s); and, at another side, a longitudinal passage adapted for locating almost entirely the slide and for attaching permanently one side of it. Another side of the slide is firmly secured to the panel. In one embodiment, the longitudinal channel is C-shaped in cross section. Opposing niches are formed. Each opposing niche is adapted to capture at least a flange of at least one of several cantilever supports. In another embodiment, instead of the longitudinal channel, the elongated horizontal body comprises a central longitudinal wall extending, close to its top, outwardly and upwardly and forming a longitudinal top recess. Close to its bottom, the central longitudinal wall extends outwardly and downwardly forming a longitudinal bottom recess. The longitudinal top and bottom recesses are functionally equivalent to the niches. In another embodiment, the elongated horizontal body is provided with a central longitudinal wall extending, from midway of its height, outwardly, then upwardly and downwardly. Thus, longitudinal top and bottom recesses equivalent to the above recesses are formed.
Description




I. BACKGROUND OF 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 and/or 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, U.S. Pat. No. 6,152,312, dated Nov. 28, 2000 and granted to Nava et al. for a “SUSPENDING SYSTEM FOR VARIOUS TYPES OF HANGING SUPPORTS, IN PARTICULAR DESIGNED TO FIT WARDROBES ” describes a System structurally formed by three components, i.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. U.S. Pat. No. 4,569,450, dated Feb. 11


th


1986 and granted to Dillingham for 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 are provided on the parallel side flanges for supporting and retaining the hanger members. Dillingham's 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 INVENTION




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.




Thus, a first objective of the present invention is to provide an extendable rack which is reliable, simple and allows the material and labor costs to be reduced. Such savings may be passed to the users, which constitute an undeniable advantage. A second objective of this invention is to provide a well-engineered extendable rack characterized by compactness and including a well-tested, mass produced slide.




Broadly stating, the present invention provides an extendable rack adapted for retaining one or more cantilever support(s) and also adapted for attaching to a panel via a slide. The extendable rack comprises an elongated body including, at one side, means for retaining one or more cantilever support(s); and, at another side, a longitudinal passage adapted for locating almost entirely and for attaching permanently the slide that is also firmly secured to the panel.




In accordance with one aspect of the present invention, the means for retaining one or more cantilever support(s) includes an elongated horizontal body provided with a longitudinal channel, C-shaped in cross section, with a perimeter defined by a standing segment extending, at the top, into a downwardly curved segment and, at the bottom, into an upwardly curved segment, so that opposing niches are formed. Each opposing niche is adapted to capture at least a flange of at least one of several cantilever supports.




In accordance with another aspect of the present invention, the means for retaining one or more cantilever support(s) includes an elongated horizontal body provided with a central longitudinal wall, extending, close to the top, outwardly and upwardly and forming a longitudinal top recess. Close to the bottom, the central longitudinal wall extends outwardly and downwardly forming a longitudinal bottom recess. The longitudinal top and bottom recesses are adapted to capture at least one flange of at least one of several cantilever supports.




In accordance with still another aspect of the present invention, the means for retaining one or more cantilever support(s) is provided with a central longitudinal wall extending from midway of its height, outwardly, then upwardly and downwardly, thus forming longitudinal top and bottom recesses adapted to capture at least one flange of at least one of several cantilever supports.




In a last aspect of the present invention, the elongated horizontal body, having longitudinal cavities, is provided, at a front extremity, with a finger-pull having upper and lower projections for press fitting into the longitudinal cavities. A cap attached to a back extremity of the elongated horizontal body also comprises upper and lower projections for press fitting into the longitudinal cavities.

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


and for attaching permanently one side of the latter; other sides of slide


400


being firmly secured to a fixed panel (not shown). Thus, elongated horizontal body


200


is suitable for being glidingly assembled on slide


400


.




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


with U-shaped in cross section, and a length also 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 formed between upright segment


220


and horizontal segments


222


and


224


are rounded. A first horizontal dimension L


1


of longitudinal passage


210


is lesser than a second horizontal dimension L


2


of a mounted slide


400


. Thus, slide


400


extends laterally beyond horizontal 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


. Fasteners


258


disposed in holes


256


are used to attach slide


400


to elongated horizontal body


200


.




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 top and bottom recesses


264


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


.




In 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


268


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 further explanation of the same appears to be unnecessary. For example, precision ball bearing drawer slides are sold under the trademark Accuride™ by Accuride, Santa Fe Springs, Calif.




Cantilever supports


300


are designed in various shapes to accommodate different items, such as neckties, belts, trays etc.
