Abstract
A soft-touch drawer pull including a substantially rigid substrate and a rubber-like plastic attached to the outer surface of the substrate. The substrate preferably includes teeth or catches on an inner surface that interact with corresponding recesses or holes on a drawer unit or other article to allow the drawer pull to be easily secured to the unit or article. Preferably, the drawer pull further includes catches that interact with snaps on a drawer to further secure the drawer pull to the drawer.
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
.
