container top 20a, 20b. In the illustrated embodiment of Fig. 1a, the ner top
3O 20a is releasably connected to the storage container 14b such that the container top
20a 1) prevents the storage container 14b from being non-releasably connected to
the e container 14a and 2) permits the e container 14b to be releasably
connected to the storage container 14a disposed above the container top 20a.
The non-releasable connection portions 22 of the container tops 20a, 20b and
the lower non—releasable connection portion 18 of the storage containers 14a—14d
P-EP-SW0392034
may be a first type of non-releasable connection portion different from a second type
of connection portion d by the upper non-releasable connection portion 16 of
the storage containers 14a-14d. Just for example, in one ment, the first type
of connection n may be a female type connector, and the second type of
connection portion may be male type connector configured to be connected to the
female type connector. However, it should be appreciated that in other
embodiments, the female and male types connectors may be interchanged. That is,
the non-releasable connection portions 22 of the container tops 20a, 20b and the
lower non-releasable connection ns 18 of the storage containers 14a-14d may
be male type connectors, and the upper non—releasable connection portion 16 of the
storage containers 14a-14d may be female type connectors.
in one embodiment, the apparatus 10 also es a base storage container
26 that is ively releasably or non-releasably connected to one of the storage
ners 14a-14d. in one embodiment, the base storage container 26 includes a
non-releasable connection portion (not shown) constructed and arranged in a similar
manner as the upper non-releasable tion portion 16 of the storage containers
14a-14d, wherein the non-releasable connection portion of the base storage
container 26 may be selectively non-releasably connected to a lower non-releasable
connection portion 18 of one of the storage containers 14a-14d or to a non-
releasable connection portion 22 of one of the container tops 20a, 20b.
In the ment shown in Fig. 1a, the top storage container 15 is non-
releasably connected to the storage container 14a to form upper container module
70. Middle container module 72 is formed by the container top 20a, the storage
ner 14b, the storage container 14c, and the storage container 14d that are non-
releasably ted to one r. Lower container module 74 is formed by the
container top 20b and the base container 26 that are non-releasably connected to
each other. It should be appreciated that the container modules 70, 72, 74 may have
other configurations and may be formed using various combinations of one or more
of the ner tops 20a, 20b, storage containers 14a-14d, base storage container
26, or top storage container 15 in other embodiments. It should also be appreciated
that the apparatus 10 may have other container modules formed using additional
storage containers and container tops that are non-releasably connected to one
another. These container modules may then be releasably connected to one
another. In one ment, each container module includes a container top that

It should be appreciated that the number, combination, andIor arrangement of
storage containers, top container, container tops, and base container may vary. It
should also be appreciated that the number of latches and the location of the latches
may also vary. The storage containers may have the same configuration as one
another or may have different configurations from one another. For example, there
can be one or more e containers of equal size or there can be one or more
storage containers that are different in size compared to one or more other storage
containers. in one embodiment, there can be a plurality of storage containers that
can be non-releasably connected to each other in any order or configuration. As
used herein, “non-releasable” does not necessarily mean that it is impossible to
release the connection n parts or disconnect the parts that are non-releasably
ted. Instead, the term eleasable” may refer to the inability of a user to
disconnect a connection manually, without the use of a tool or implement. in
addition, the parts that are non-releasably connected may be connected during
manufacture, such as at the factory, or at any point before being sold to consumers
or users. This may enable manufacturers or others to easily assemble the s
ments of the apparatus 10 before the apparatus 10 is sold to consumers or
users. in other words, the manufacturer or others assembling the various
embodiments of the apparatus 10 may select the storage containers 14a—14d, base
container 26, top storage ner 15, and container tops 20—20b to be non—
ably ted to one another. The manufacturers or other assembling the
apparatus 10 may also select the storage containers 14a-14d to be releasably
connected to one another. Thus, the manufactures or others ling the
apparatus 10 may select the combination of storage ners 14a-l4d, base
container 26, top storage container 15, and container tops 203-20b to be non-
releasably or releasably connected to one other. However, in another embodiment,
the parts may be non-releasably connected by consumer after being sold to the
consumer. in contrast, parts that are “releasably” connected as contemplated herein
are easier to disconnect from one another or e their connection from one
another. That is, parts that are “releasably” ted may be released manually by
the consumers or users without the use of a tool or implement.
P-EP-SW0392034
Fig. 2 shows an embodiment of the apparatus 10 with the container modules
70, 72, 74 that are released from their releasable connections with one another. In

portions 16 when the upper non-releasable connection portions 16 are being non-
ably connected to the lower non—releasable connection portions 18, which will
P-EPrSWO392034
be described in more detail below. Thus, in one embodiment, the non-releasable
connection portions 22 may have similar configurations and parts as the lower non-
releasable tion portion 18 and may operate with the upper non-releasable
tion 16 in a similar manner. That is, the connection between the non-
releasable connection portion 22 and the upper non-releasable connection portion 16
may be similar to the connection shown in Fig. 10 between the lower and upper non-
releasable tions 16, 18. Accordingly, this feature enables the cturer or
others assembling the apparatus 10 to select the ation of storage containers
and container tops to be non—releasably connected together to form container
modules, as mentioned above.
Fig. 90 shows in detail the non-releasable connection between the container

includes the elongated recess 118 at the bottom side 59 thereof. The elongated
recess 118 is constructed and arranged to receive the elongated protrusion 116
provided on the container top 20a (see Fig. 11b). As mentioned above, the
elongated recesses 118 and the protrusions 116 facilitate the alignment of the
latches 28a, 28b with the latch engaging structures 31. Feet 142 may extend from
the bottom side 59 of the storage container 140 to facilitate placement of the storage
container 14c on a surface. The other storage ners may also be provided with
the feet 142 and the recesses 118. As shown in Fig. 11b, openings 150 may be
provided on the container top 20a near or at the non-releasable connection portions
22. The openings 150 of the container top 20a may receive the feet 142 of the
storage container placed above the container top 20a. The other container tops may
have the same configuration as the container top 20a.
P-EP—SW0392034
The storage containers, container tops, base storage container, and top
storage container may be non-releasably connected as follows in accordance with an
embodiment. As mentioned above, the storage containers, container tops, base
e container, and top storage container may be non-releasably connected at
any point before the assembly 10 is sold to the er or user. As shown in Figs.
8a—8b, the storage container 14b may be non—releasably connected to the storage
container 140. To non—releasably connect the storage containers 14b, 140, the lower
non—releasable connection ns 18 of the storage container 14b may be aligned
with the upper non-releasable tion portions 16 of the storage container 14c.
The upper and lower non-releasable connection portions 16, 18 may then be moved
towards one another such that the upper non—releasable connection portions 16 are
received in the space 141 (as shown in Fig. 12) of the lower leasable
connection portion 18. During this movement, referring to the parts shown in Fig. 10,
the bottom surface 138 of the lower non-releasable connection portion 18 may
t and push against the inclined contact surface 132 of the protrusion 126 of the
upper non-releasable connection portion 16. The lower non-releasable connection
portion 18 and/or the upper non-releasable connection portion 16 may e
resilient material that enables portions thereof to flex so that the sions 126 may
be further ed in the hollow space 141 of the lower non-releasable connection
portion 18. The bottom surface 138 of the lower non-releasable connection ns
18 may move down along the contact surface 132 of the protrusions 126, whereupon
the protrusions 126 snap into the openings 128 of the lower non—releasable
connection portions 18. In one embodiment, the lower surface 136 of the lower non—
releasable connection portion prevents the disengagement or nection of the
non-releasable connection between the upper and lower connection portions 16, 18
by abutting against the stop surface 130 of the protrusion 126 of the upper non-
releasable connection portion 16. When the storage containers 14b, 140 are non—
releasably connected, the lower surface 138 of the lower non—releasable connection
portions 18 of the storage container 14b may rest on the ledge surface 140 of the
3O storage container 14c. It should be appreciated that the other storage containers,
base storage container, and top storage container may be non-releasably connected
in a similar manner. rly, the container top 20a or other container tops may be
connected to storage ner 14b or other e containers, base storage
container, or top storage ner in a similar manner.
P-EP~SWO392034
After the storage containers, container tops, base storage container, and top
storage container have been leasably connected to form container s,
the container modules may then be releasably connected to each other. For
example, in the embodiment shown in Fig. 2, the upper container module 70 may be
releasably connected to the middle container module 72 using latches 28a, and the
middle container module 72 may be releasably connected to the lower container
module 74 using latches 28b. To releasably connect container module 70 to
container module 72, for example, the container module 70 may be placed above the
container module 72. The container module 70 may then be brought closer to the
container module 72 until the ted protrusions 116 of the ner top 20a of
container module 72 are received in the elongated es 118 of the storage
container 14a of container module 70. Accordingly, the container module 70 rests on
the container module 72 and the latches 28a that are pivotally connected to the
container top 20a of the container module 72 are aligned with the latch engaging
structures 31 provided on the storage ner 14a of container module 70. The
latches 28a may then be pivoted upwards from a lowered position (see for example
Fig. 5) upwards towards the storage container 143 until the upper ng members
114 of the latches 28a are engaged with the latch engaging structures 31.
Accordingly, the container modules 70 and 72 are releasably connected to one
another (see for example, Fig. 1a). To release the connection between the container
modules 70 and 72, the user may pivot the latches 28a downwards so that the upper
engaging members is ed from engagement with the latch engaging ures
31. The container module 70 may then be separately carried from container module
72. It should be appreciated that other container modules may be releasably
connected or disconnected in a similar manner as the container modules 70, 72
described above. The container module 72 may be releasably connected to the
lower container module 74 in a similar manner using the s 28b.
Fig. 12 shows a bottom perspective view of the storage container 14b. In this
embodiment, an opening 122 is formed under the latch shield 81 to provide access to
an actuating portion 124 of the latch member 120. An opening 123 may be provided
in the front wall 50 of the drawer to enable a n of the latch member 120 to pass
therethrough. The actuating portion 124 is constructed and ed to be
actuatable by the user to move release the ng portion 119 from engagement
with the latch engaging member 121, which will be described in more detail below.
The latch shield 81 of the other e containers may have the same configuration,
P-EP»SW0392034
and the latch shield 86 of the base storage container 26 may have the same
configuration as the latch shield 81.
Fig. 13a shows the engaging portion 119 of the latch member 120 in the first
position and engaged with the latch engaging member 121. As ned above, in
the first position, the engaging n 119 is engageable with the latch engaging
member 121 to latch the drawer 78b in the closed position to prevent sliding
movement of the drawer 78b. The latch member 120 may be pivotally connected to
the drawer 78b at a pivot point 160.
in this embodiment, the latch member 120 is biased upwards by a biasing
member 152, taking the form of a compression spring in this embodiment. The
biasing member 152 ts a contact portion 154 of the latch member 120 and
pushes the engaging portion 119 upwards towards the latch engaging member 121.
The biasing member 152 may be provided on a protrusion 151 extending upwards
from the drawer 78b. The latch member 120 may also e a cam surface 156
near or at the engaging portion 119. The cam surface 156 is constructed and
arranged to contact a contact surface 158 during sliding movement of the drawer 78b
to the closed position, which will be described in more detail later. The latch member
120 may also include an upper surface 159 that may contact the contact surface 158
during sliding movement of the drawer 78b to the closed position. The contact
e 158 may be an edge or any other portion of the container top or storage
ner disposed above and connected to the storage container 14b. in this
embodiment, the latch engaging member 121 prevents the drawer 78b from being
slid in the direction of A by engaging with the engaging n 119, which takes the
form of a hook in this embodiment.
Fig. 13b shows the latch member 120 in the second position and disengaged
from the latch engaging member 121. As mentioned above, in the second position,
the latch member 120 is releasable from engagement with the latch ng
member 121 to permit sliding movement of the drawer 78b. As shown in this
embodiment, when the latch member 120 is in the second position, the latch member
3O 120 is pivoted downwards in the clockwise direction such that the engaging n
119 is removed from engagement with the latch engaging member 121 and the
contact portion 154 is pushed against the biasing member 152, thus ssing the
g member 152. The actuation portion 124 is constructed and arranged to
receive the user’s fingers during pivoting of the latch member 120 from the first
position to the second position. The latch members 120 of the other storage
PrEP-SWO392034
containers and the latch member 108 of the base storage container 26 may have the
same configuration as the latch member 120 described above and may e in a
similar manner.
Figs. 14a—14c illustrate the operation of sliding the drawer from the open
position wherein access to contents of the drawer 78b are permitted to the closed
position wherein access to the contents of the drawer are prevented in ance
with an embodiment. ln this ment, the user may push the latch shield 81 to
slide the drawer 78b towards the closed position (e.g., in the direction of B). The
drawer 78b may be in the open position initially, as shown in Fig. 14a. In the
embodiment shown in Figs. 14a-14c, the latch engaging member 121 is provided on
the container top 20a. The user may push against the latch shield 81 to slide the
drawer 78b towards the closed position, as shown in Fig. 14b. During this sliding
movement, the cam surface 156 of the latch member 120 may push against the
contact surface 158 provided on the container top 20a, as shown in Fig. 14b. This
may cause the latch member 180 to pivot downwards along pivot point 160.
Accordingly, the contact portion 154 of the latch member 120 may push against the
biasing member 152. As the drawer 78b is further slid towards the closed on,
the contact surface 158 may contact the upper surface 159 of the latch member 120,
as shown in Fig. 140, and may cause the latch member 120 to pivot further
downwards such that the contact portion 154 of the latch member 120 further
compresses the biasing member 152. As the drawer 78b is pushed further in the
direction of B, the latch member 120 may clear the contact surface 158 and may
snap upwards in the rclockwise direction due to the bias of the biasing
member 152, causing the hook—shaped engaging portion 119 to be d with the
latch engaging member 121, as shown in Fig. 15a. Thus, the drawer 78b is locked in
the closed position. Accordingly, in the operation described above, the latch shield
81 may shield the latch member 120 from the user such that the user does not have
to access the latch member 120 to lock the drawer 78b in the closed on. In
other words, the drawer 78b can be locked “automatically” by the user pushing the
drawer 78 from the open position to the closed position via the latch shield 81.
The drawer 78b may be unlocked and slid to the open on as s.
The drawer 78b may initially be locked in the closed position, as shown in Fig. 15a,
wherein the engaging n 119 of the latch member 120 is engaged with the latch
engaging member 121 provided on the container top 20a. ln this position, the
biasing member 152 is biasing the engaging portion 119 upwards so that it is
P-EP-SW0392034
engaged with the latch engaging member 121. The user may insert fingers into the
opening 122 formed by the latch shield 81 to access the actuating portion 124 of the
latch member 120. The user may push the actuating portion 124 upwards to pivot
the latch member 120 along the pivot point 160. As a result, the latch member 120
may be pivoted downwards in the clockwise direction such that the engaging portion
119 is removed from engagement with the latch engaging member 121, and the
contact portion 154 is compressing the biasing member 152 downwards, as shown in
Fig. 15b. After the engaging portion 119 has been moved downward and
disengaged from the latch engaging member 121 and the drawer 78b is ed,
the user may pull the drawer 78b towards the open position (e.g., in the direction of
A), as shown in Fig. 150. After the user ceases ion of the actuating portion
124, the biasing member 152 may snap the latch member 120 s in the
counterclockwise direction to the position shown in Fig. 14a. As mentioned above,
the other drawers may be locked/unlocked and moved between the open and closed
positions in a similar . The latch member 108 may operate in a r
manner as latch member 120 to latch the bin 82 in the closed position. However,
instead of sliding movement, the bin 82 may be d between the open and closed
ons.
Figs. b illustrate rear plan views of the assembly 10. in Fig. 16a, the
pulling handle 24 is retracted in the handle receiving portion 88. A handle lock 90 is
provided on the handle receiving portion 88. As mentioned above, the handle lock
90, which may take the form of a , is constructed and ed to be moveable
between 1) a locked position wherein the pulling handle 24 is locked at a selected
position such that sliding movement of the pulling handle 24 between the retracted
position and the extended position is prevented and 2) an unlocked position wherein
sliding movement of the pulling handle 24 between the retracted position and the
extended position is permitted. The handle lock 90 may engage with one of the
plurality of openings 92 provided in the extension bar 27 when the pulling handle 27
is in the locked position. Fig. 17 shows the handle lock 90 in more detail. In this
embodiment, the handle lock 90 includes an actuation portion 162 constructed and
arranged to be actuatabie to move the handle lock 90 to the disengaged position. in
some embodiments, the handle lock 90 may be a type of rocker lock that pivots or
rocks about a pivot point.
Fig. 18 shows a side view of the handle lock 90 in the ed position. The
handle lock 90 includes the actuation portion 162 and an engagement portion 164,
P-EP-SW0392034
which takes the form of a protrusion in this embodiment, that is constructed and
ed to be received in one of the openings 92 when the handle lock 90 is in the
locked position such that sliding movement of the g handle 24 between the
ted and extended positions is prevented. That is, to lock the handle lock 90 in
the locked position in one embodiment, the engagement portion 164 is received in
one of the openings 92. To unlock the handle lock 90, the ment portion 164 is
removed from the openings 92. A pivot axis 166, which may be defined by a pivot
pin, is provided between the actuation portion 162 and the engagement portion 164.
Accordingly, the lock handle 90 may “rock” along the pivot axis 166. The actuation
n and the engagement n 164 may be integrally formed or may be
separate pieces connected to each other to form the handle lock 90.
Fig. 19a shows a detailed side view of the actuation portion 162 of the handle
lock 90. A biasing member 168 biases the handle lock 90 in the locked position. in
this embodiment, the biasing member 168 contacts at least a portion of the actuation
portion 162 ofthe handle lock 90. The ion portion 162 of the handle lock 90 is
actuatable against the bias of the biasing member 168 to pivot the lock to the
unlocked position, as shown in Figs. 18 and 19b. It should be appreciated that in
other embodiments, the biasing member 168 may be located at other locations
and/or may take other forms.
The pulling handle 24 may be slid to adjust the height of the handle portion 24
as follows in accordance with an embodiment. The handle lock 90 may lly be
biased in the unactuated and locked position, as shown in Fig. 19a. When the
handle lock 90 is in this position, the engagement portion 164 is received in one of
the openings 92 to lock the pulling handle 24 at a selected position such that g
movement of the pulling handle 24 is prevented. The user may push the actuation
portion 162 of the handle 90 against the bias of the biasing member 168 to the
actuated on, as shown in Figs. 18 and 19b. This may cause the handle lock 90
to pivot in the counterclockwise direction. Accordingly, the engagement portion 164 is
removed from the opening 92. The pulling handle 24 may then be slid up/down
3O between the retracted and extended positions with respect to the handle receiving
portion 88. After the desired position of the pulling handle 24 has been selected and
an opening 92 is aligned with the engagement portion 164, the user may release
ion of the actuation n 162, whereupon the biasing member 168 may snap
the actuation portion 162 in the clockwise direction back to the unactuated position
shown in Fig. 19a. Accordingly, the engagement portion 164 of the handle lock 90
P»EP>SW0392034
may be received in the selected opening 92 to lock the g handle 24 at the
selected position. Alternatively, the user might not have to align an opening 92 with
the engagement portion 164. For example, the user may cease actuation of the
ion portion 162 regardless of the alignment of an opening 92 with the
engagement portion 164. To lock the handle lock 90, the user may then proceed to
move the pulling handle 24 up or down. The contact between the engagement
portion 164 and the surface 91 of the extension bar 27 prevents the handle lock 90
from being moved back to the locked on. ingly, the handle lock 90 may
be in the unlocked position, as shown in Fig. 18. As the user moves the pulling
handle 24 up or down, one of the openings 92 may become d with the
engagement portion 164, whereupon the biasing member 168 may snap the handle
lock 90 in the clockwise direction so that the engagement portion 164 is received in
the opening 92 that is aligned therewith. Accordingly, the pulling handle 90 is once
again locked in the selected position.
