Abstract
A drawer interlinking system for a storage cabinet is disclosed herein. The cabinet includes a frame, a first sliding assembly, and a second sliding assembly. Each sliding assembly is movable between an extended position and a retracted position relative to the frame. The frame includes a flexible member coupled at a first end to the first sliding assembly. The line is directed by a first guide coupled to the frame in association with the first sliding assembly, a guide assembly coupled to the frame and spaced apart from the first guide, a glide assembly coupled to the frame by a tension member, and a second guide coupled to the frame in association with the second sliding assembly and spaced apart from the guide assembly. The flexible member is coupled at a second end to the second sliding assembly, so that when one sliding assembly is extended from the frame the other sliding assembly is retracted into the frame. The guide assembly can comprise a left pulley connected to a right pulley. The glide assembly may include a tension member, such as a spring. Further, the cabinet may include an instop bumper that centers and aligns the sliding assemblies when the sliding assemblies are in a retracted position.
Description
FIELD OF THE INVENTION
The present invention generally relates to storage cabinets having sliding assemblies. More specifically, the present invention relates to a mobile storage cabinet having interlinked drawers where each drawer of the cabinet is movable between an extended and a retracted position so that when a worker extends one drawer from the cabinet the other drawer is retracted into the cabinet.
BACKGROUND OF THE INVENTION
Storage cabinets for stowing and organizing contents have been known for many years. Such cabinets typically include a plurality of drawers. Contents (e.g., files, papers, office utensils) are stowed in the drawers of the cabinet for access by workers. Typically, the center of gravity of the cabinet shifts toward the front of the cabinet when a worker extends a drawer to retrieve the contents therein. The center of the gravity is further shifted toward the front of the cabinet when a second or third drawer is also extended to retrieve the contents therein. The shift in the center of gravity toward the front of the cabinet may cause the cabinet to tip forward resulting in the spillage of the stored contents, or even overturn.
Several attempts have been made to prevent cabinets from tipping forward or overturning. One attempt includes providing a heavy weight attached to the back end of a cabinet. The weight can decrease the degree to which the center of gravity of the cabinet shifts forward as a drawer is extended. However, cabinets of this type are bulky and weighty, which reduces the mobility of the cabinet and increases costs of manufacture and shipping. Another attempt to prevent cabinets from overturning includes anchoring the cabinet to a floor or wall. However, anchoring the cabinet eliminates the mobility of the cabinet.
Still another attempt to prevent cabinets from overturning includes using a cord linking the drawers of the cabinet and having only enough slack to allow one drawer to be completely extended at a given moment in time. When so linked, the cord causes one drawer to retract when another drawer is extended. However, the linking action of the drawers is not smooth or immediate because of slack in the cord, which inhibits a direct response between the extension of one drawer and the retraction of another drawer. Some cabinets include a counterbalance to reduce the slack in the cord, but the counterbalance further adds to the overall weight of the cabinet, which reduces the mobility of the cabinet.
Accordingly, it would be advantageous to provide a cabinet for stowing contents that overcomes these and other disadvantages of the related art. In particular, it would be advantageous to provide a cabinet for storing items that does not easily tip forward or overturn when a drawer is extended. Further, it would be advantageous to provide a cabinet that is not weighted so greatly that it is difficult to move. It would also be advantageous to provide a cabinet with interlinked drawers so that one drawer is retracted in direct response to the extension of another drawer.
SUMMARY OF THE INVENTION
The present invention relates to a drawer interlinking system for a storage cabinet. The cabinet includes a frame, a first sliding assembly, and a second sliding assembly. Each sliding assembly (preferably, a drawer) is selectively configured between an extended position and a retracted position relative to the frame. The system includes a flexible member having a first end coupled to the first sliding assembly. The system also includes a first guide, coupled to the frame relative to the first sliding assembly, that directs the flexible member. The system further includes a first primary guide, coupled to the frame and spaced a distance from the first guide, that directs the flexible member. The system still further includes a connecting guide, coupled to the frame by a connecting member, that directs the flexible member. In addition, the system includes a second primary guide, coupled to the frame and spaced a distance from the first guide, that directs the flexible member. Further, the system includes a second guide, coupled to the frame relative to the second sliding assembly and spaced a distance from the first and second primary guides, that directs the flexible member. The flexible member has a second end coupled to the second sliding assembly, so that when the first sliding assembly is extended from the frame the second sliding assembly is retracted into the frame.
The present invention further relates to an interlinking system for a storage cabinet. The cabinet provides a frame, a first sliding assembly, and a second sliding assembly (such as drawers), each sliding assembly being movable between an extended position and a retracted position relative to the frame to open and close the drawers, respectively. The system includes a first guide coupled to the frame relative to the first sliding assembly. The system also includes a first primary guide coupled to the frame and spaced a distance from the first guide. The system further includes a connecting guide coupled to the frame by a connecting member. The connecting member prevents slack from accumulating in the flexible member. The system still further includes a second primary guide coupled to the frame and spaced a distance from the first guide. In addition, the system includes a second guide coupled to the frame in association with the second sliding assembly and spaced a distance from the first and second primary guides. Further, the system includes a flexible member having a first end and a second end. The first end of the flexible member is coupled to the first sliding assembly, the second end of the flexible member is coupled to the second sliding assembly. The flexible member is directed by the first guide, the first primary guide, the connecting guide, the second primary guide, and the second guide. When the first sliding assembly is extended from the frame the second sliding assembly is retracted into the frame.
The present invention further relates to a method of operating an interlinking system. The interlinking system provides a storage cabinet having a frame, a first sliding assembly and a second sliding assembly. Each sliding assembly is selectively configured between an extended position, a retracted position, and a combination thereof relative to the frame. The interlinking system further provides a flexible member having a first end coupled to the first sliding assembly. The interlinking system still further provides a first guide, coupled to the frame relative to the first sliding assembly, that directs the flexible member. Also, the interlinking system provides a first primary guide, coupled to the frame and spaced a distance from the first guide, that directs the flexible member. Further, the interlinking system provides a glide, coupled to the frame by a connecting member, that directs the flexible member. The interlinking system also includes a second primary guide, coupled to the frame and spaced a distance from the first guide, that directs the flexible member. Still further, the interlinking system includes a second guide, coupled to the frame relative to the second sliding assembly and spaced a distance from the first and second primary guides, that directs the flexible member. The flexible member has a second end coupled to the second sliding assembly. The method includes extending the first sliding assembly to create tension on the flexible member. The method further includes directing the flexible member with the first guide. The method still further includes directing the flexible member with the first primary guide. In addition, the method includes directing the flexible member with the glide assembly. Further, the method includes directing the flexible member with the second primary guide. Still further, the method includes directing the flexible member with the second guide.

is designed to be mobile and capable of being positioned under a work surface (e.g., table, desk, counter). Bottom drawer
26
and top drawer
28
are removable between an extended and retracted position relative to frame
24
. Drawers
26
and
28
are preferably inclined slightly toward the rear of cabinet
22
. According to a particularly preferred embodiment, drawers
26
and
28
are inclined one-half degree toward the rear of cabinet
22
. The incline of drawers
26
and
28
permits some countermeasure to the downward force applied by contents
92
(e.g., files, books, office products) of drawers
26
and
28
. Cabinet
22
further includes a weight
90
rigidly mounted to the back of cabinet
22
by a fastener shown as a screw
86
through a hole
88
. According to a particularly preferred embodiment, weight
90
is approximately twenty-seven pounds for a two-drawer, twenty-four inch high mobile cabinet. Weight
90
provides some countermeasure to the downward force applied by contents
92
of drawers

or
28
are pulled with increased force when lock
112
is engaged. Drawers
26
and
28
of cabinet
22
further include an instop bumper (not shown). The instop bumper centers and aligns drawers
26
and
28
when the drawers are in a retracted position.
Flexible member
70
includes ends
72
and
74
, and tabs
76
. Tabs
76
are situated at the terminus of first and second ends
72
and
74
of flexible member
70
. Flexible member
70
can be any material (e.g., cable, string, wire) capable of interaction with and direction by plurality of guides
30
. According to a particularly preferred embodiment, flexible member
70
is “7×7” coated cable, Part No. 892800008 available from Grand Rapids Controls of Grand Rapids, Mich. Line attachment assembly
80
secures first and second ends
72
and
74
of flexible member
70
to the back of bottom and top drawers
26
and
28
, respectively (see FIG.

). Line attachment assembly
80
prevents flexible member
70
from exiting drawers
26
and
28
through a hole
104
. Line attachment assembly
80
includes a clip
82
. According to a particularly preferred embodiment, clip
82
is rectangular-shaped having an “L”-shaped inner channel
84
. Tabs
76
of first and second ends
72
and
74
of flexible member
70
fit through hole
104
of bottom and top drawers
26
and
28
, respectively. Inner channel
84
permits clip
82
to circumscribe flexible member
70
. The outer perimenter of clip
82
is greater than the outer perimeter of hole
104
, and the width of tab
76
is wider than the diameter of inner channel
84
of clip
82
. Accordingly, when glide assembly
50
creates tension on flexible member
70
, tab
76
presses against clip
82
, which in turn, presses against hole
104
of drawers
26
and
28
so that tab
76
is secured to the back of bottom and top drawers
26
and
28
, respectively
A bottom drawer guide
32
(such as a first guide), a top drawer guide
34
(such as a second guide), a guide assembly
40
(such as a first and second primary guide) and glide assembly
50
(such as a connecting guide) interact with and direct flexible member
70
. The portion of flexible member
70
associated with first end
72
interacts with and is directed by bottom drawer guide
32
associated with bottom drawer
26
. Bottom drawer guide
32
is mounted to frame
24
of cabinet
22
by a connecting member. According to a particularly preferred embodiment, the connector is an elongate finger
46
that extends from frame
24
of cabinet
22
, and bottom drawer guide
32
is a plastic pulley that rotates. (See
FIG. 6.
) Line attachment assembly
80
secures first end
72
of flexible member
70
to clip
82
and the back of bottom drawer
26
. The portion of flexible member
70
associated with second end
74
interacts with and is guided by top drawer guide
34
associated with top drawer
28
. Top drawer guide
34
is mounted to frame
24
of cabinet
22
by a connector (e.g., elongate finger
46
). According to a particularly preferred embodiment, top drawer guide
34
is a plastic pulley that rotates. (See
FIG. 6.
) Line attachment assembly
80
secures second end
74
of flexible member
70
to clip
82
and the back of top drawer
28
.
Guide assembly
40
further interacts with and directs flexible member
70
. (See
FIG. 5.
) Guide assembly
40
is spaced a distance from top and bottom drawer guides
32
and
34
. Guide assembly
40
includes a left and a right guide
42
and
44
. According to a particularly preferred embodiment, left and right guides
42
and
44
of guide assembly
40
are plastic pulleys that rotate, and further, left guide
42
is preferably coupled to right guide
44
(or vice versa). Guide assembly
40
is mounted to frame
24
of cabinet
22
by a connector. According to a particularly preferred embodiment, the connector is elongate finger
46
that extends from frame
24
of cabinet
22
, and left and right guides
42
and
44
are plastic pulleys that rotate. In operation, when drawers
26
and
28
are extended and retracted, left guide
42
of guide assembly
40
interacts with and directs the portion of flexible member
70
associated with second end
74
, and right guide
44
of guide assembly
40
interacts with and directs the portion of flexible member
70
associated with first end
72
.
Glide assembly
50
still further interacts with and directs flexible member
70
. (See
FIG. 4.
) Glide assembly
50
preferably includes a lead
52
, and a tension member (such as a connecting member). Glide assembly
50
serves to prevent slack from accumulating in flexible member
70
. The tension member is preferably a tensioned device (e.g., spring, elastic band, sponge). According to a particularly preferred embodiment, tension member is a spring
56
, such as a coil metal spring (e.g., Part No. 80120110 available from Wolverine Coil, Incorporated of Grand Rapids, Mich.). Spring
56
has a spring constant great enough to grab any slack in flexible member
70
necessary when drawers
26
and
28
are extended or retracted. Hooks are provided at each end of the spring
56
. A first hook
58
of spring
56
is inserted through a hole
106
of frame
24
of cabinet
22
. A second hook
60
of spring
56
is inserted through a hole
114
of lead
52
. Lead
52
is preferably rectangular shaped having a passage
54
. Passage
54
is curved (e.g., “U”-shaped) to interact with and direct flexible member
70
through lead
52
. Lead
52
functions like a pulley in relation to flexible member
70
, but does not rotate. Lead
52
is positioned in the horizontal plane so that the portions of flexible member
70
associated with first and second ends
72
and
74
do not strike one another. Contact occurs between the portions of flexible member
70
associated with first and second ends
72
and
74
if lead
52
is positioned in the vertical plane.
A stop mechanism
64
is located between lead
52
and guide assembly
40
. A fastener, such as a screw
108
, is inserted through a hole
110
to connect stop mechanism
64
to frame
24
of cabinet
22
. The tension on glide assembly
50
created by the extension of bottom or top drawers
26
and
28
causes lead
52
to move toward guide assembly
40
. Stop mechanism
64
prohibits lead
52
of glide assembly
50
from striking guide assembly
40
. Stop mechanism
64
includes a lip
66
provided between the portions of flexible member
70
associated with first and second ends
72
and
74
. Lip
66
ensures that the portions of flexible member
70
associated with first and second ends
72
and
74
do not strike one another. Spring
56
is fully extended so that lead
52
is adjacent to stop mechanism
64
when bottom drawer
28
is in the fully extended position and bottom drawer
26
is in the fully retracted position (or vice versa) (see FIGS.
3
A and
3
C), or alternatively, when both drawers
26
and
28
are in a partially extended position relative to frame
24
(see, e.g., FIG.
3
B).
Referring to
FIG. 1
, drawers
26
and
28
are in a fully retracted position. In operation, when bottom drawer
26
is subsequently extended (see, e.g.,
FIG. 3A
) the following occurs: lead
52
and spring
56
move toward stop mechanism
64
; right guide
44
of guide assembly
40
interacts with and directs the portion of flexible member
70
associated with first end
72
; but the portion of flexible member
70
associated with second end
74
, left guide
42
of guide assembly
40
, and top drawer guide
34
remain essentially motionless. Likewise, when drawers
26
and
28
are in a fully retracted position (as shown in FIG.
1
), and top drawer
28
is subsequently extended (see, e.g.,
FIG. 3C
) the following occurs: lead
52
and spring
56
move toward stop mechanism
64
; left guide
42
of guide assembly
40
interacts with and directs the portion of flexible member
70
associated with second end
74
; but the portion of flexible member
70
associated with first end
72
, right guide
44
of guide assembly
40
, and bottom drawer guide
32
remain essentially motionless.
Operation of interlinked drawers
26
and
28
of cabinet
22
between an extended and a retracted position is best shown by reference to
FIGS. 1 and 3A
through
3
C. Referring to
FIG. 1
, drawers
26
and
28
of cabinet
22
are both in a fully retracted position. Spring
56
is only slightly extended and glide assembly
50
exerts a slight tension that grabs slack in flexible member
70
.
Bottom drawer
26
must be extended (as shown in
FIG. 1
) to retrieve the contents
92
therein. The extension of bottom drawer
26
exerts a tension on first end
72
of flexible member
70
. Consequently, first end
72
of flexible member
70
exerts a tension on glide assembly
50
, which causes glide assembly
50
to move toward stop mechanism
64
. The extension of the bottom drawer
26
(when top drawer
28
is in a retracted position) does not exert a significant tension on second end
74
of flexible member
70
. When bottom drawer
26
is in a fully extended position (as in
FIG. 3A
) spring
56
is fully extended and stop mechanism
64
prevents lead
52
from moving further toward guide assembly
40
.
Referring to
FIG. 3A
, bottom drawer
26
is in a fully extended position and top drawer
28
is in a fully retracted position. Top drawer
28
must be extended to obtain contents
92
therein. As top drawer
28
is extended, the portion of flexible member
70
associated with second end
74
exerts a tension on glide assembly
50
. Stop mechanism
64
prevents glide assembly
50
from further moving toward guide assembly
40
. Spring
56
remains fully extended so glide assembly
50
neither takes nor donates a significant amount of slack to flexible member
70
. Consequently, second end
74
of flexible member
70
exerts a tension on first end
72
of flexible member
70
, flexible member
70
interacts with and is directed by passage
54
of glide assembly
40
, which causes bottom drawer
26
to partially retract relative to frame
24
(as in
FIG. 3B
, showing bottom drawer
26
in a partially retracted position and top drawer
28
in a partially extended position). Bottom drawer
26
and top drawer
28
are interlinked by flexible member
70
, plurality of guides
30
, and glide assembly
50
. Thus, the further extension of top drawer
28
causes bottom drawer
26
to be further retracted into frame
24
until top drawer
28
is in a fully extended position and bottom drawer
26
is in a fully retracted position (as shown in FIG.
3
C).
Top drawer
28
can be retracted from its fully extended position (as shown in FIG.
3
C). In so doing, spring
56
grabs the slack in flexible member
70
. Accordingly, the following occurs: spring
56
moves toward the front of cabinet
22
; lead
52
moves toward the front of cabinet
22
; the portion of flexible member
70
associated with second end
74
interacts with and is directed by left guide
42
of guide assembly
40
; but flexible member
70
associated with first end
72
, right guide
44
of guide assembly
40
, and bottom drawer guide
32
remain essentially motionless.
FIG. 8
shows a drawer interlinking system
120
according to an alternative embodiment of the present invention. System
120
includes a middle, a top and a bottom sliding assembly shown as a middle, a top and a bottom drawer
126
,
128
, and
124
, respectively. Bottom drawer
124
is not interlinked to middle and top drawers
126
and
128
. In all other respects, system
120
is essentially the same as system
22
in structure, function, and operation, and the like reference numerals identify like elements. According to a particularly preferred embodiment, the drawer that is not interlinked (i.e., bottom drawer
124
as shown in
FIG. 8
) is located between the interlinked drawers (such as middle and top drawers
126
and
128
as shown in FIG.
8
).
FIGS. 9A
,
9
B, and
9
C further detail drawer interlinking system
120
of
FIG. 8
according to a particularly preferred embodiment. Middle and top drawers
126
and
128
are interlinked such that top drawer
128
is retracted when middle drawer
126
is extended (see, e.g., FIG.
9
A). Likewise, middle door
126
is retracted when top drawer
128
is extended (see, e.g., FIG.
9
C). Bottom drawer
124
is not interlinked and may be extended or retracted regardless of the position of middle and top drawers
126
and
128
. According to an alternative embodiment, the top drawer (or multiple drawers) is not interlinked to the bottom and middle interlinked drawers in a three (or more) drawer file cabinet, and the top and middle drawers are smaller in size than the bottom drawer.
Although only a few exemplary embodiments of the present invention have been described in detail in this disclosure, those skilled in the art who review this disclosure will readily appreciate that many modifications are possible in the exemplary embodiments (such as variations in sizes, structures, shapes, weights and proportions of the various elements, values of parameters, mounting arrangements, use of materials, number of drawers, or placement of drawers) without materially departing from the novel teachings and advantages of the invention. Accordingly, all such modifications are intended to be included within the scope of the invention as defined in the appended claims. Other substitutions, modifications, changes and omissions may be made in the design, operating conditions and arrangement of the preferred embodiments without departing from the spirit of the invention as expressed in the appended claims.
