LATCHING MECHANISM
BACKGROUND
1. Field [0001] Example embodiments relate to a latching mechanism usable with a drawer and a drawer system.

2. Description of the Related Art [0002] Drawers are commonly used in various structures ranging from dressers to work benches. Many of these drawers do not have a latching mechanism thus enabling a person to simply pull the drawer out of the structure to access contents of the drawer.
Other drawers have built-in latch systems which require an unlatching step to gain access to contents of the drawer. Some latching systems are configured so that when a handle of a drawer is pulled, the latching system is actuated thus allowing access to contents of the drawer.
SUMMARY

[0003] The inventor has noticed that drawers with latching systems are, in some cases, preferable over those without. In situations where the drawers are mobile, for example, a drawer used in a moving vehicle, latches prevent the drawers from sliding out of the structures they are associated with. However, many of the latching systems are relatively complicated to fabricate, install, and use. As such, the inventor set out to design a new latching mechanism which is usable with drawers. However, the latching system developed by the inventor can be used with many structures such as, but not limited to, electrical boxes. As such, the inventive concepts disclosed herein should not be limited to drawers systems as the inventive concepts may be implemented in a variety of ways.

[0004] In at least one nonlimiting example a latching mechanism may be comprised of a mounting frame, a handle having an arm, and at least one latch unit. In example embodiments, the at least one latch unit may have a pivotally supported latch, a biasing element restraining structure, a biasing element having a first end restrained by the biasing element restraining structure and a second end restrained by a biasing element retaining region of the latch. In example embodiments the latch may include a tail region configured to contact the arm of the handle so that when the handle is rotated the arm exerts a force against the tail region of the latch to rotate the latch.

DETAILED DESCRIPTION

[00029] Example embodiments will now be described more fully with reference to the accompanying drawings, in which example embodiments of the invention are shown. The invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments . .
. .
are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the sizes of components may be exaggerated for clarity.

[00030] It will be understood that when an element or layer is referred to as being "on," "connected to," or "coupled to" another element or layer, it can be directly on, connected to, or coupled to the other element or layer or intervening elements or layers that may be present. In contrast, when an element is referred to as being "directly on,"
"directly connected to," or "directly coupled to" another element or layer, there are no intervening elements or layers present. As used herein, the term "and/or"
includes any and all combinations of one or more of the associated listed items.

[00031] It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, components, regions, layers, and/or sections, these elements, components, regions, layers, and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, and/or section from another elements, component, region, layer, and/or section.
Thus, a first element component region, layer or section discussed below could be termed a second element, component, region, layer, or section without departing from the teachings of example embodiments.

[00032] Spatially relative terms, such as "beneath," "below,"
"lower," "above,"
"upper," and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the structure in use or operation in addition to the orientation depicted in the figures. For example, if the structure in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The structure may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[00033]
Embodiments described herein will refer to plan views and/or cross-sectional views by way of ideal schematic views. Accordingly, the views may be modified depending on manufacturing technologies and/or tolerances. Therefore, example embodiments are not limited to those shown in the views, but include modifications in configurations formed on the basis of manufacturing process.
Therefore, regions exemplified in the figures have schematic properties and shapes of regions shown in the figures exemplify specific shapes or regions of elements, and do not limit example embodiments.

[00034] The subject matter of example embodiments, as disclosed herein, is described with specificity to meet statutory requirements. However, the description itself is not intended to limit the scope of this patent. Rather, the inventors have contemplated that the claimed subject matter might also be embodied in other ways, to include different features or combinations of features similar to the ones described in this document, in conjunction with other technologies.
Generally, example embodiments relate to a latching mechanism usable with a drawer and a drawer system.

[00035] FIG.
1 is a perspective view of a drawer system 10000 in accordance with example embodiments. As shown in FIG. 1, the drawer system 10000 may include a . .
. .
frame 50 supporting a plurality of drawers 1000, 2000, and 3000. Although FIG.

illustrates the drawer system 10000 as having three drawers, the number of drawers illustrated is for the purpose of example only as the drawer system 10000 may include more than three drawers or less than three drawers. In example embodiments, the drawer system 10000 may be used for multiple purposes including, but not limited to, storing tools and various types of equipment.

[00036] FIG. 2 is a perspective view of drawer 1000. In this nonlimiting example embodiment, the drawer 1000 is comprised of a storage compartment 100 having a drawer latching mechanism mounted on a front thereof. FIG. 3 illustrates a front view of the drawer 1000 and FIG. 4 illustrates an exploded view of the drawer 1000.
FIG. 5 is a partial side view of the drawer 1000 showing a close-up view of one end thereof.
As shown in the various figures, the drawer latching mechanism may be comprised of several parts including, but not limited to, a mounting frame 200, a handle 300, a first latch unit 400, and a second latch unit 500.

[00037] Referring to FIG. 4, the storage compartment 100 may resemble a box having a floor 110, a back wall 120, two side walls 130 and 140, and a front wall 150.
The front wall 150 may have a top edge 151 which may partially support the mounting frame 200. The front wall 150 may also include a pair of holes which may facilitate connecting the mounting frame 200 to the front wall 150. For example, a pair of screws may be used to attach the mounting frame 200 to the front wall 150 and the pair of holes may allow a pair of screws to pass through the front wall 150 and penetrate into the mounting frame 200 to securely connect the mounting frame 200 to the front wall 150. It is understood that while a pair of holes are described to facilitate a connection between the front wall 150 and the mounting frame 200, in another embodiment only one hole is provided since the mounting frame 200 may be connected to the front wall 150 by only a single screw. In another embodiment, three holes in the front wall 150 may be provided to allow for three screws to connect the front wall 150 to the mounting frame 200. In yet another embodiment, the front wall 150 includes more than three holes to allow for more than three screws to connect the mounting frame 200 to the front wall. Of course, the invention does not require that the mounting frame 200 be connected to the front wall 150 by screws. For example, an adhesive may be applied between the mounting frame 200 and the front wall 150 to attach the mounting frame 200 to the front wall 150, in which case, screws are not required thus eliminating a need for the pair of holes. As such, in another embodiment, the front wall 150 does not have a pair of holes to facilitate connecting the mounting frame 200 to the front wall 150.

[00038] FIG.
6 is a perspective view of the mounting frame 200 and FIG. 7 is a cross-section view of the mounting frame 200. In one embodiment the mounting frame 200 may be fabricated from an extrusion process and therefore may have a substantially constant cross-section, however, the invention is not limited thereto. As shown in FIGS. 6 and 7, the mounting frame 200 may include a front wall 210, a bottom wall 220, a back wall 230, and an extension 240 having a J-shaped end 250 which forms a channel 260. The channel 260, may have a thickness tc which is about the same as a thickness of the top edge 151 of the front wall 150. As such, the top edge of the front wall 150 may reside in the channel 260 as shown best in FIG. 5. In example embodiments, the extension 240 may resemble a substantially flat plate which may bear against the front wall 150 of the storage compartment 100.

[00039] In example embodiments, the mounting frame 200 may include a ledge area 232 which extends from the back wall 230 to pivot structure 270 which includes an arcuate surface 272. The arcuate surface 272 may form a channel 275 configured to receive a beaded portion 370 of the handle 300. More specifically, the arcuate surface 272 is configured to trap the beaded portion 370 of the handle 300 in a manner that allows the handle 300 to pivot with respect to the mounting frame 200 while preventing the beaded portion 370 from translating transversely with respect to the channel 275.
As will be explained shortly, this will allow an arm 360 of the handle 300 to pivot within the mounting frame 200 and actuate latches of the latch units 400 and 500.

[00040] In example embodiments, the mounting frame 200 may include various structures to reinforce the pivot structure 270. For example, the mounting frame 200 may include a first leg 222 extending from the bottom wall 220, a second leg extending from the back wall 230, and a third leg 274 extending from the pivot structure 270 such that each leg 222, 232, and 274 terminate at a common supporting structure 280. These latter elements add strength and rigidity to the mounting frame 200 which is desirable in a drawer system 10000.

[00041] FIG. 8 is a back view of the mounting frame 200. As shown in FIG. 8, the back wall 230 of the mounting frame 200 may include a pair of holes 234 and which may be alignable with the previously described holes of the storage compartment 100 in order to attach the mounting frame 200 to the storage compartment 100.
However, consistent with the previous description, rather than having two holes to . .
. .
connect the mounting frame 200 to the storage compartment, the mounting frame may have only a single hole or more than two holes, or may not have a hole at all in the event another attaching means is used to attach the mounting frame 200 to the storage container 100. For example, if an adhesive is used, holes in the back of the mounting frame 200 may be omitted.

[00042] FIG. 9 is a view of the handle 300 in accordance with example embodiments. FIG. 10 is a cross-section of the handle 300. In example embodiments, the handle 300 may be formed from an extrusion process, as such, the handle 300 may have a substantially constant cross-section. As shown in FIGS. 9 and 10, the handle 300 may include a grip 310 which may be gripped by the human hand. As shown in FIGS. 9 and 10 the handle 310 includes the beaded portion 370 which has an arcuate outside surface 372. The beaded portion 370, in cross-section, may resemble a circle having a diameter about the same as, or slightly smaller than, the arcuate surface 272.
Thus, the beaded portion 370 may rotate within the arcuate surface 272. As also shown in FIGS. 9 and 10 is the arm 360. The end of the arm 360 has an upward and downward motion as the beaded portion 370 is rotated within channel 275. These actions are best shown in FIGS. 11-14 where FIG. 11 shows the handle 300 having the beaded portion 270 captured within the channel 275 formed by the arcuate surface 272.
FIG. 12 shows a cross section of this configuration. FIG. 13 shows the handle rotated backwards. FIG. 14 illustrates a cross-section of the handle 300 and the mounting frame 200 with the handle 300 rotated backwards. As shown in FIGS. 11-the arm 360 rotates with a space 290 of the mounting frame 200. Between the front wall 210 and the pivot structure 270.

=

[00043] In example embodiments, a length of the handle 300 LH may be longer than a length of the mounting frame 200 LM. As such, ends of the handle 300 may extend beyond ends of the mounting frame 200 and into the latching units 400 and 500.
The handle 300 may actuate latches therein.

[00044] FIGS. 15 to 19 illustrate an example of the first latch unit 400 and the second latch unit 500. In example embodiments, the second latch unit 500 may be substantially the same as the first latch unit 400, as such, a detailed description thereof is omitted for the sake of brevity. It is pointed out, however, that the second latch unit 500 may structurally mirror the first latch unit 400.

[00045] As one skilled in the art will readily appreciate, FIGS. 15 to 19 illustrate various views of the first latch unit 400 and the second latch unit 500 along with component parts thereof. As shown in FIGS. 15 to 19, the first latch unit 400 may be comprised of end cap body 410 having a first wall 420, a second wall 430, a third wall 440, and a floor 450. The first latch unit 400 may also include a biasing element restraining structure 460. In one nonlmiting example embodiment, the biasing element restraining structure 460 may be configured to restrain an end of a biasing element 470.
For example, the biasing element restraining element 460 may resemble an L-shaped ledge extending from the second wall 430. In example embodiments, the first latch unit 400 may further include a latch 480 which may be pivotally supported in the first latch unit 400. For example, the first latch unit 400 may include a pin 490 about which the latch 480 may pivot. For example, the pin 490 may penetrate the latch 480 and the latch 480 may pivot about an axis of the pin 490. The pin 490, in one nonlimiting example embodiment, may be supported at one end by a spacer 494 and at another end . .
. .
by the second wall 430. It is understood the second latch unit 500 may also include an end cap body 510 having a first wall 520, a second wall 530, a third wall 540, a floor 550, a biasing element restraining structure 560, a biasing element 570, a pivotally supported latch 580, a pin 590, and a spacer 594 similar to the previously described end cap body 410, first wall 420, second wall 430, third wall 440, floor 450, biasing element restraining structure 460, biasing element 470, latch 480, pin 490, and spacer 494.

[00046] In example embodiments, the latch 480 may include a biasing member retaining region 482. For example, in one nonlimiting example embodiment, the biasing member retaining region 482 is a depression in the latch 480 and the depression may receive a second end of the biasing element 470 which may be, but is not required to be, a coil spring. In one nonlimiting example embodiment, the biasing element 470 may be restrained by the biasing element restraining element 460 and the biasing member retaining region 482 so that the biasing member is in compression. In this configuration, the latch 480 would be maintained in a downward position as shown in FIGS. 15 and 16. However, because the latch 480 is pivotally supported within the first latch unit 400, a force applied to the tail region 484 of the latch 480 may cause the latch 480 to rotate to an upward position as shown in FIG. 17 provided the force applied be great enough to overcome the force applied by the biasing element 470.
However, as soon as the force applied to the tail region 484 is removed, the force from the biasing element 470 would cause the latch 480 to move back towards the downward position.

[00047] In example embodiments, the latch units 400 and 500 may be secured to the mounting frame 200 in various ways. In one embodiment, the latch units 400 and =
500 are attached to ends of the mounting frame 200 by an adhesive. In another embodiment, the latch units 400 and 500 and the mounting frame 200 may include structures to enable them to be joined together by fasteners, for example, screws. For example, in the nonlimiting example embodiment of FIG. 7, the mounting frame includes a first insertion area 282, a second insertion area 284, and a third insertion area 288. These insertion areas 282, 284, and 288 may be configured to receive threaded ends of fasteners. Similarly, the first and second latch units 400 and 500 may include channels 487, 587 and 488, 588 that have the same spacing as insertions areas 282 and 284 so that screws that penetrate the channels 487 and 488 can be received in the insertion areas 282 and 284. In addition, the insertion area 288 may be in substantial alignment with pins 490 and 590 which may pass through apertures 489 and 589 in the second walls 430 and 530 of the latch units 400 and 500 so that if the ends of the pins 490 and 590 are threaded, the threaded ends of pins 490 and 590 may be received in the third insertion area 288 to attach the first and second latch units 400 and 500 to the mounting frame 200.

[00048] FIGS.
20 and 21 illustrate a cross-section of the latch unit 400 with an end of the handle 300 protruding therein. In FIGS. 20 and 21 it is understood the handle 300 is supported by the mounting frame 200. As shown in FIGS. 19 and 20, a force applied to the handle 300 may cause the handle 300 to rotate. The rotation of the handle 300 causes the end 362 of the arm 360 to press against the tail 484 of the latch 480 thus causing the latch 480 to rotate. In this example, it is understood the latch 480 protrudes into an opening of the frame 50 but that the rotated latch 480 allows the latch 480 to be moved to a position allowing the drawer 1000 to be pulled out of the frame 50. Thus, pulling back on the handle 300 rotates the latch 480 in a manner that allows the latch 480 to pass through the opening of the frame 50 allowing the drawer 1000 to be drawn out of the frame 50. This same action would also cause latch 480 to also be rotated to a position where it may be pass through another opening in the frame 50

[00049] In the embodiment of FIGS. 2-21 the drawer 100 has a depth about the same as a depth of the latching mechanism. However, this application includes additional inventive features which allow the latching mechanism to be used with deeper drawers. For, example, drawers 2000 and 3000 may be somewhat deeper than the drawer 1000. To account for the difference in depth, the latching mechanism is configured to connect to extension pieces that allow the latching mechanism to work with deeper drawers. FIG. 22, for example, illustrates drawer 3000 with an extension piece 600 and two end caps 700 and 800 arranged at ends of the extension piece 600.
FIGS. 23 ¨ 28 show various inventive features associated with the latching mechanism, the extension piece 600 and the end caps 700 and 800.

[00050] In example embodiments, the extension piece 600 and end caps 700 and 800 may be attached to the first and second latch units 400 and 500 as well as the mounting frame 200. FIG. 23, for example, shows these pieces connected together and FIG. 24 shows these pieces in an exploded view.

[00051] FIG. 25 is a perspective view of extension piece 600 and FIG.

illustrates a cross-section view of the extension piece 600. As shown in FIGS.
25 and 26, the extension piece 600 may resemble a tubular member having a substantially rectangular cross section. For example, the extension piece may have a top wall 620, a first side wall 630, a second side wall 640, and a bottom wall 650 which may substantially resemble a hollow rectangular tube. Extending from the top wall 620 is a protrusion 622 which may be configured to reside in a receiving structure 286 of the mounting frame 200 (see at least FIG. 7). In example embodiments, a length of the extension piece 600 may be substantially the same as a length LM of the mounting frame 200. It is understood that this manner of connecting the extension piece 600 to the mounting frame 200 is exemplary only. In another embodiment the mounting frame 200 may have a protrusion similar to the protrusion 622 extending from a bottom of the bottom wall 200 and the extension piece 600 may have a channel similar to the receiving structure 286. In this latter embodiment, the extension piece 600 may connect to the mounting structure 200 by inserting the mounting structures protrusion into the channel of the extension piece 600. Of course, these latter described channels and protrusions may be omitted as the extension piece 600 may be secured to the mounting structure 200 by another means, for example, an adhesive. In this latter embodiment it is envisioned an adhesive may be applied between the top wall 620 of the extension piece 600 and the bottom wall 220 of the mounting structure 200 to connect the two pieces together.

[00052] FIG.
27 illustrates example endcaps 700 and 800. As shown in FIG. 27, the end cap 700 may resemble box-like structures having a top wall 730, a first side wall 710, a second side wall 720 and a back wall (not labeled). Protruding from the top wall 730 is a protrusion 750 which may be configured to insert into a receiving area 452 of end cap 400. FIG. 28, for example, shows the protrusion 750 aligned with the receiving area 452 of the first end cap 400 as well as the protrusion 750 residing in the first end cap 400. End cap 800 may have similar features. For example, end cap may also include a top wall 830, a first side wall 810, a second side wall 820, a bottom wall 840, and a back wall (not labeled). The end cap 800 may also include a protrusion 850 which may insert into a receiving area of the second end cap 500.

[00053] In example embodiments, the first end cap 700 and the second end cap 800 may include a lip 780 and 880. In example embodiments, lips 780 and 880 may be inserted into the ends of the extension piece 600 so that outside surfaces of the extension piece 600 and the end caps 700 and 800 may be substantially flush.
In example embodiments an adhesive may be applied to the lips 780 and 880 to secure the lips 780 and 880 to the extension piece so they may forma a substantially monolithic structure. In the alternative, screws may be provided as a fastening means to connect the end pieces 700 and 800 to the extension piece 600. For example, the first and second extension pieces 700 and 800 may be formed with passages 770 and 870 which allow a threaded member to pass through and screw into a receiving area 652 of the extension piece 600. Thus, this latter example allows the end pieces 700 and 800 to be removably coupled to the extension piece 600.

[00054] In example embodiments, the extension piece 600 serves both an aesthic and functional purpose. From a functional perspective, the extension piece 600 may serve as a means to secure the latching mechanism to the storage compartment 100.
For example, holes may be cut into the back of the extension piece 600 which may be aligned with holes in the front of the storage compartment and the holes may allow screws be used to connect the extension piece to the storage compartment 100.
