Description




BACKGROUND OF INVENTION




The present invention relates to furniture and, more specifically, to handles for drawers.




Many articles of furniture include drawers to provide storage space. Desks, tables and cabinets typically include one or more drawers to store or conceal items and provide easy access to those items. Often, the storage space required by a user cannot be satisfied by conventional furniture, for example, desks or tables. Accordingly, a drawer pedestal including one or more drawers is used to increase the storage space. Conventional drawer pedestals are constructed either to stand alone or be positioned under a desk, table or similar furniture.




Most furniture and associated drawers are constructed from wood or metal, and fastened together with screws or bolts. Accordingly, the furniture and drawers typically are quite heavy. This makes shipping expensive and movement of the pedestals by an end user relatively difficult. Moreover, when furniture components are disassembled, they are not readily stackable because the components are constructed from rigid wood or metal, which makes handling and storage of the disassembled components space-consuming.




Recently, furniture is being constructed from plastic because of its lightweight. In many cases, its strength is similar to that of wood or metal. Some consumers, however, believe that plastic furniture looks and feels “cheap,” and thus are unwilling to purchase and use it. For example, when physically tapped on by a user, most plastic units create a hollow, resounding thud, which makes the unit sound structurally inadequate. Additionally, drawers of plastic furniture units, which also are constructed of plastic, add to the unappealing feel of plastic furniture. Specifically, most plastic drawers are a single molded part, and to decrease production costs, include an integral drawer pull which is typically an indent in the front panel of the drawer that a user may grasp. Thus, the handle is made of the same plastic as the remainder of the unit. Because many users associate the feel of plastic with inexpensive and poor quality items, these integral plastic handles have a substantially negative impact on many users' satisfaction with plastic furniture pieces.




Several attempts have been made to increase the aesthetic feel of the handles of drawers. However, all the attempts are time consuming and require additional processing of a drawer. In one process, an adhesive-backed rubber material is applied to the handle of a finished drawer. This material, however, is quite thin and, therefore, difficult to permanently secure to the finished unit. Misalignment, wrinkling and tearing of the material commonly complicates its attachment to drawers. In another process, a liquid rubber-like compound is applied to the integral drawer handle to increase the feel and gripability of the handle. After time, however, the material tends to delaminate from the drawer unit, resulting in an aesthetically unappealing, frayed or torn drawer handle cover. In another process, a second plastic material is molded over a portion of an already-formed plastic drawer to form the handle. This method is problematic, especially where the drawers are large or include multiple internal compartments, because a large complex mold must be used to injection mold the rubber-like material onto the formed drawer.




Thus, many opportunities exist to provide a drawer that includes an inexpensive and easily attached drawer pull that is aesthetically pleasing and/or soft to the touch.




SUMMARY OF THE INVENTION




The aforementioned problems are overcome by the present invention wherein a drawer pull is provided that easily and securely attaches to a drawer. Preferably, the drawer pull includes a “soft-touch” material that significantly improves the aesthetics and feel of the drawer pull.




In a preferred embodiment, the drawer pull includes a plastic substrate and a softer material that is secured to the substrate via molding or adhesive. The softer material is a soft, rubber-like material. In a more preferred embodiment, the substrate defines a channel and includes one or more locking tabs that project into the channel. The locking tabs may project from opposite sides of the channel toward one another.




In an even more preferred embodiment, the drawer to which the drawer pull is secured includes recesses or slots or holes adapted to receive the locking tabs so that the pull interlocks with the drawer. Where the drawer pull includes opposing locking tabs in the channel, the drawer may also include recesses to engage the opposing locking tabs to enhance the interlock of the drawer pull to the drawer.




The drawer pull of the present invention offers many benefits. The pull is easy to manufacture and install. The pull may be manufactured with a two-shot injection process where the rigid substrate and soft material are molded to one another in a relatively small mold. The its interlocking tabs, the pull may easily be snapped onto the drawer, making installation of the drawer-pull a simple step in assembly. Furthermore, different pulls may be colored differently and installed on drawers to the custom order of the end user.











These and other objects, advantages, and features of the invention will be readily understood and appreciated by reference to the detailed description of the invention and the drawings.

In the embodiment of

FIG. 6

, a rib


120


protrudes from the panel recess


118


. The rib


120


includes a number of rib recesses


122


, which add strength to the rib


120


. The rib recesses


122


preferably are substantially rectangularly shaped indents spaced along the rib


120


, and may be located on both the internal panel side


114


and the external panel side


116


. Any number of recesses may be used as desired. In one embodiment, there are at least two rib recesses


122


located on each of the internal panel side


114


and external panel side


116


of the rib


120


.




With further reference to

FIG. 6

, the front drawer panel


98


includes snaps


126


preferably located on both the left recess side


127


and right recess side


128


of the panel recess


118


. Each snap


126


generally includes either a tab


129


or a hole or recess


127


, defined by the front panel


98


, or both the tab


129


and hole or recess


127


. The holes and tabs may be of any shape or size, but preferably the tab and the hole are of complimentary shape and size to receive and hold catch


140


of handle


100


. The snaps


126


are located on each of the left recess side


124


and right recess side


128


of the front drawer panel


98


above the rib


120


. Preferably, the snaps


126


do not compromise the strength of rib


120


. Optionally, the bottom edge of the hole or recess


127


of each snap


126


is adjacent the rib


120


. And optionally, any number of snaps


126


may be used. The snaps


126


may be located in the top half of each of the left recess side


124


and right recess side


128


of the panel recess


118


.




In one embodiment, each tab


129


is a substantially triangular protrusion extending from the left recess side


124


and right recess side


128


. Each tab


129


forms the top edge of the respective snap


124


. The tabs


129


further interlock with the catch


140


of the handle


100


to secure the handle


100


to the front drawer panel


98


after placement of the handle


100


on the rib


120


.




B. Handle




With reference to

FIGS. 3-5

, the handle


100


includes a substrate


130


and a material


132


secured to the substrate. Preferably, the substrate


130


is made from a substantially rigid material, for example, a plastic, such as high-density polyethylene, polypropylene, nylon, polyvinyl chloride, polyethylene terepthalate, polycarbonate and any combination of the foregoing. Optionally, any other material may be used as desired. The substrate


130


includes a substrate inner surface


134


and a substrate outer surface


136


. The substrate


130


defines a channel or slot


150


therein configured to interlock over the rib


120


when the handle


100


is installed on the panel


98


. As shown, the channel is of a substantially U-shaped cross section, however, other cross sections may be used as desired. Moreover, although the channel extends across substantially the entire width of the handle


100


, it may be segmented to extend across only portions of the pull.




Referring to

FIGS. 5 and 7

, the substrate


130


preferably includes teeth


138


projecting inwardly into the channel. Each tooth


138


has a base


142


and a tip


144


. The base


142


of each tooth


138


is attached to the substrate inner surface


134


so that when the substrate


130


is placed over the rib


120


, the tip


144


of each tooth


138


interlocks with a rib recess


122


. This interlock secures the handle


100


to the panel


98


. Optionally, the teeth


138


and rib recesses


122


may be replaced with one another as desired. For example, the teeth may be associated with the rib


120


and corresponding recesses may be associated with the substrate


130


. In one embodiment, two teeth


138


are located on each of the left inner side


135


and right inner side


137


of the channel


150


. More or less teeth may be included as desired.




Optionally, catches


140


are located on the substrate inner surface


134


. Each catch includes a catch base


146


and a catch tip


148


. The catch base


146


of each catch


140


is attached to the substrate inner surface


134


of the substrate


130


so that, when the substrate


130


is placed over the rib


120


, the catch tip


148


of each catch


140


interlocks with d snap


124


on the front drawer panel


98


. The tabs


129


help ensure a tight, interlocking fit between the catches


140


and the snaps


124


to prevent the handle


100


from becoming dislodged from the drawer panel


98


during use. The front drawer panel


98


includes at least as many snaps


124


as there are catches


140


on the substrate


130


. Optionally, the snaps and catches may be absent from the drawer panel and the handle as desired.




The material


132


is attached to substantially all of the substrate outer surface


136


. The material


132


is preferably a low-density, textured plastic but may be made of any material capable of being attached to the substrate


130


, for example, polyvinyl chloride (PVC), thermoplastic rubber (TPR), thermoplastic urethane (TPU), thermoplastic polyurethane (TPE), and thermoplastic polyolefins (TPOs). Any material that improves the feel, look and/or gripability of the handle


100


may be used as desired.




In one embodiment, the material


132


is injection molded to the substrate outer surface


136


in a two-shot molding process. Optionally, the material may be molded to the substrate


130


after the substrate is formed, or adhered to the substrate with a suitable adhesive. Additionally, the color of the material


132


may vary. This allows the end-user or manufacturer to choose the desired handle color before attachment of the handle


100


to the drawer assembly




II. Assembly




To secure the handle


100


to the front panel


98


, a user or a robot in an automated process, grasps the handle


100


and aligns the channel


150


with the rib


120


, and the handle


100


with the panel recess


118


. The user presses the handle


100


downward onto the front panel


98


. As the teeth


138


engage the rib


120


, the user continues to press forcibly downward so that the channel


150


opens up slightly. The angle of the faces of the teeth


138


and the rounded corners of the rib


120


assist in opening the channel. The handle


100


is continued to be pushed forcibly downward until the teeth pass the rib


120


and the channel snaps closed, pressing the teeth into the rib recesses


122


thereby interlocking the handle


100


to the drawer. Additionally, the catches


140


pass over the tabs


129


and interfit into the holes or recesses


127


to further interlock the upper portion of the handle


100


into the panel recess


118


. The handle


100


may be assembled in a production line or by the end user after delivery of the unit.




III. Alternative Embodiment




In an alternative embodiment of

FIGS. 8 and 9

, the rib


220


of the front drawer panel


298


further includes a number of locking recesses


222


. The rib


220


includes a rim


219


that extends substantially the entire length of the rib


220


so that the rib


220


and the rim


219


form a substantially T-shaped cross-section. Optionally, the rib and rim may form an inverted L-shaped cross section as desired. Locking recesses


222


are spaced along the base


221


of the rib


220


, but may be spaced anywhere on the rib as desired. These recesses


222


may be located on the internal panel side


214


, the external panel side


216


, or both. Any number of recesses


222


may be used as desired. In a preferred embodiment, there are at least two locking recesses


222


located on each of the internal panel side


214


and external panel side


216


of the rib


220


. And optionally, the recesses may be apertures defined through the base


221


, or other region of the rib


220


.




A guide


228


preferably extends from the top


223


of each aperture


222


to the top


225


of the rib


220


. Each guide


228


is a straight protrusion from the rib


220


having a first end


229


and a second end


230


. The first end


229


of each guide


228


abuts the top


223


of a locking recess


222


. The second end


230


of each guide


228


abuts the rim


219


. Each guide


228


is substantially continuous with both the top


223


of the respective locking recess


222


and the rim


219


so that a smooth junction exists between the guide


228


and each of the locking recess


222


and rim


219


.




As the handle


100


is placed over the rib


220


, the tip


144


of each tooth


138


clears the rim


219


and rides along a guide


228


. The interaction of the teeth


138


and the guides


228


prevents each tooth


138


from interlocking with a rib recess


122


as the handle


100


is pressed onto the rib


220


. As each guide


228


terminates at a locking recess


222


, the tip


144


of each tooth


138


passes over the top


223


of the locking recess


222


and interlocks in the locking recess


222


. In this interlocked configuration, it is extremely difficult to dislodge the tips


144


of the teeth


138


from the locking recesses


222


. As a result, the handle


100


is not easily removed from the rib


220


, that is, it is “permanently” secured to the drawer.




If it is necessary to remove the handle


100


from the rib


220


, the guides


228


aid in the removal of the handle


100


by preventing the teeth


138


from interlocking with recesses


122


as the handle


100


is removed. Each tip


144


, after being dislodged from the corresponding locking recess


222


, passes over the top


223


of the locking recess


222


and rides along the guide


228


until the tip


144


clears the rim


219


and the handle


100


is removed from the rib


220


.
