Before any embodiments of the disclosure are explained in detail, it is to be understood that the disclosure is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. Use of "including" and "comprising" and variations thereof as used herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. Use of "consisting of" and variations thereof as used herein is meant to encompass only the items listed thereafter and equivalents thereof.

As shown in <FIG>, a tool container or case <NUM> includes a base <NUM> coupled to a lid <NUM> by a hinge <NUM>. The case <NUM> may be stacked with one or more other cases <NUM>, or even stacked with multiple cases included in Milwaukee Electric Tool Company's PACKOUT™ platform. The case <NUM> may also be stored within other, larger tool cases. In general, the case <NUM> is used for storing oscillating multi tool (OMT) blades and accessories <NUM> (<FIG>). Typically, OMT blades and accessories <NUM> include a first portion <NUM> for engaging a work piece and a second portion <NUM> (e.g., an offset anchor) for engaging and/or accommodating mounting to an OMT.

The base <NUM> includes a first or lower surface <NUM> and walls <NUM> extending away from the lower surface <NUM>. The lower surface <NUM> and the walls <NUM> define a cavity <NUM>. In some embodiments, the lower surface <NUM> is a separate element from the base <NUM>, such as a tray, panel, or the like that is selectively insertable into the cavity <NUM> and removable from the base <NUM>. A handle <NUM> is coupled to at least one of the walls <NUM> or to the lid <NUM>. The case <NUM> also includes guides <NUM> positioned adjacent to the lower surface <NUM>. The guides <NUM> form apertures or openings in the lower surface <NUM>.

In the illustrated embodiment, the guides <NUM> are formed directly on the lower surface <NUM>. Each guide <NUM> is generally circular in shape and includes a channel <NUM> (<FIG>). In the illustrated embodiment, the channel <NUM> is a double bayonet channel <NUM>, but could alternatively be a single bayonet channel. As shown in <FIG>, the guides <NUM> are arranged in rows along the lower surface <NUM>. The guides <NUM> may also be aligned in columns and/or arranged in a grid. Each guide <NUM> may receive a tool holder insert <NUM>. The tool holder insert <NUM> may also be referred to as a pin or a peg. Each peg <NUM>, which will be described further below, includes a projection <NUM> complementary to the double bayonet channel <NUM> (<FIG>). Each peg <NUM> is configured to receive the second portion <NUM> (i.e., tool mounting portion) of an OMT blade or accessory <NUM>.

Referring back to <FIG>, the base <NUM> further includes a latch <NUM> disposed on one wall <NUM>, and the lid <NUM> includes a latch receiving portion <NUM>. In some embodiments, the latch <NUM> may be disposed on the lid <NUM>, and the latch receiving portion <NUM> may be formed on the base <NUM>. The latch <NUM> is movable (e.g., slidable, pivotable, detachable, etc.) relative to the wall <NUM> and selectively engaged with the latch receiving portion <NUM> to retain the lid <NUM> to the base <NUM> in a closed position (<FIG>). When the latch <NUM> is disengaged from the latch receiving portion <NUM>, the lid <NUM> may be pivoted about the hinge <NUM> into an open position. The lid <NUM> may be pivoted about the hinge <NUM> from <NUM> degrees (i.e., closed position) to <NUM> degrees.

Referring now to <FIG>, the case <NUM> is stackable with other cases <NUM> at an interface <NUM> (<FIG>) between the base <NUM> of one case <NUM> and the lid <NUM> of another case <NUM>. In some constructions of the case, the interface is compatible with the PACKOUT™ platform referenced above. The base <NUM> includes feet <NUM> for stabilizing the case <NUM> on a surface. The feet <NUM> extend away from the base <NUM> and have a trapezoidal profile. The base <NUM> also includes a generally rectangular recess <NUM>. The feet <NUM> are positioned on the base <NUM> and form corners of the rectangular recess <NUM> (<FIG>).

The lid <NUM> also includes a generally rectangular recess <NUM>. Each corner of the recess <NUM> is formed to match the shape of the feet <NUM> such that when the base <NUM> of one case <NUM> is placed on the lid <NUM> of another case <NUM>, the feet <NUM> of the base <NUM> may be received in the recess <NUM> formed on the lid <NUM> and inhibit movement of the cases <NUM> in a horizontal plane (i.e., generally parallel to the interface <NUM>). The recesses <NUM>, <NUM> are also configured to receive decals and or merchandising/product information.

Referring now to <FIG>, each peg <NUM> includes a base portion <NUM>, an insert portion <NUM> extending from the base portion <NUM> in a downward direction 55D (<FIG>), and a main body portion <NUM>. At least two wings <NUM> extend outwardly from the base <NUM> along a first axis <NUM> (<FIG>). In the illustrated embodiment, the wings <NUM> are generally planer (e.g., extending in a planer manner relative the first axis). In another embodiment, three or four wings extend outwardly from the base along the first axis. In yet another embodiment, the peg <NUM> includes a singular, generally circumferential wing that extends outwardly from the base portion <NUM> in a plane parallel to the first axis <NUM>.

The first axis <NUM> is substantially perpendicular to a central longitudinal axis of the main body portion <NUM>. Each wing <NUM> includes rounded detents, bumps, or nubs <NUM> that extend from the wings <NUM> in the downward direction 55D (<FIG>). The insert portion <NUM> includes the projection <NUM> that corresponds to the double bayonet channel <NUM>. In the illustrated embodiment, the projection <NUM> is a double bayonet projection complimentary to the double bayonet channel <NUM>. In other embodiments, the projection <NUM> could be a single bayonet projection complimentary to a bayonet channel or the double bayonet channel <NUM>. The pegs <NUM> are removably attachable to the guides <NUM> via rotational engagement between the double bayonet projection <NUM> and the double bayonet channel <NUM>. When the peg <NUM> is rotated within one of the guides <NUM>, the nubs <NUM> may also be rotated to engage (e.g., slide, snap, etc.) with adjacent guides <NUM> (<FIG>). In one example construction, the wings <NUM> may be at least partially flexible such that the wings <NUM> may deflect away from the tool case <NUM> until the nubs <NUM> snap, shift, etc. into adjacent guides <NUM>.

When engaged, the nubs <NUM> inhibit the peg <NUM> from unintentionally rotating relative to the guide <NUM>. In other words, a user may initiate inserting one of the insert portions <NUM> of the pegs <NUM> into one of the guides <NUM>, and then the user may rotate the peg <NUM> to engage the double bayonet projection <NUM> with the double bayonet channel <NUM> to lock/secure the peg <NUM> into the guide <NUM>. As the peg <NUM> is rotated, the nubs <NUM> are also rotated into adjacent guides <NUM>, thereby securing the peg <NUM> to the base <NUM>. Stated yet another way, engagement between the double bayonet projection <NUM> and the double bayonet channel <NUM> inhibits the peg <NUM> from being moved in the upward-downward direction 55U-55D relative the case <NUM>, while engagement between the nubs <NUM> and the adjacent guides <NUM> resists rotation of the peg <NUM> relative the case <NUM>.

Referring to <FIG>, the double bayonet projection <NUM> of the insert portion <NUM>, when taken through section line A-A, has a X-shaped cross section (<FIG>). The guides <NUM>, which are recessed from the lower surface <NUM>, also have a similar X-shaped cross section (<FIG>). In the illustrated embodiment, the X-shaped cross sections are generally narrow, but could alternately be generally equilateral X-shaped cross sections. As illustrated in <FIG>, the double bayonet channels <NUM> and the double bayonet projections <NUM> are configured to correspond with and engage one another. The peg <NUM> is, therefore, positionable in any channel <NUM> of the case <NUM> such that the peg <NUM> is selectively repositionable within the case <NUM>.

As illustrated in <FIG> and <FIG>, the main body portion <NUM> of the peg <NUM> is elongated and generally cylindrical and extends in an upward direction 55U opposing the downward direction 55D. The main body portion <NUM> includes ridges <NUM> that extend along the main body portion <NUM> between a circular top <NUM> and the base portion <NUM> (<FIG>). In the illustrated embodiment, four ridges <NUM> extend along the main body portion <NUM>. In other embodiments, only one ridge may extend along the main body portion <NUM>. In another embodiment, two opposing ridges may extend along the main body portion <NUM>. The four ridges <NUM> are equally spaced about the main body portion <NUM> (<FIG>) and are shaped to receive the tool mounting portion <NUM> of common OMT blades and accessories <NUM>. The circular top <NUM> blends into the ridges <NUM> to help guide OMT blades/accessories <NUM> onto the main body portion <NUM>. The circular top <NUM> and the ridges <NUM> also help reinforce the peg <NUM>.

The main body portion <NUM> of each peg <NUM> is elongated to fit multiple OMT blades/accessories <NUM> that are stacked or placed on top of one another. In the illustrated embodiment, the main body portion <NUM> is sized to receive up to five OMT blades/accessories <NUM>. In other embodiments, the main body portion <NUM> is sized to receive fewer or more OMT blades/accessories <NUM>. In some embodiments, the main body portion is configured to receive a single OMT blade/accessory to thereby reduce a depth profile of the case <NUM>.

The main body portion <NUM> is also sized to inhibit OMT blades/accessories <NUM> from sliding off of the peg <NUM> when the peg <NUM> is supported within the case <NUM> (<FIG>) and the lid <NUM> is closed. More particularly, an overall length of the main body portion <NUM> is generally the same as (or only slightly less than) a distance between the lower surface <NUM> and an inner surface of the lid <NUM>. When the lid <NUM> is closed, the circular top <NUM> of the peg <NUM> contacts (or is close to) the inner surface of the lid <NUM> such that an OMT blade/accessory <NUM> cannot slide off the top of the peg <NUM>. The circular top <NUM> may also help support the lid <NUM>.

Referring to <FIG>, <FIG>, the main body portion <NUM> also includes one or more shelves or projections <NUM>, <NUM> positioned and extending between the ridges <NUM>. In the illustrated embodiment, the main body portion <NUM> includes a pair of first projections <NUM> and a pair of second projections <NUM>. The projections <NUM>, <NUM> are positioned partway between the base portion <NUM> and the circular top <NUM>. In the illustrated embodiment, the projections <NUM>, <NUM> are positioned approximately midway between the base portion <NUM> and the circular top <NUM>, but are slightly closer to the base portion <NUM>. In other embodiments, the projections <NUM>, <NUM> may be positioned at other relative distances between the base portion <NUM> and the circular top <NUM>, depending on the size (e.g., length) of the peg <NUM>. The illustrated projections <NUM>, <NUM> are generally semi-circular and planar. In addition, the first projections <NUM> extend radially further outward from the central longitudinal axis of the main body portion <NUM> than the second projections <NUM>, such that the first projections <NUM> are generally bigger than the second projections <NUM>.

The first projections <NUM> form a resting surface or mount <NUM> for the OMT blades/accessories <NUM>. For example, some OMT blades/accessories have an offset or raised anchor (such as the offset second portions <NUM> of the OMT blades <NUM> shown in <FIG>). The resting surface <NUM> is configured to support the raised second portion <NUM> of the OMT blade <NUM>, while the first portion <NUM> of the OMT blade can still lay flat on the lower surface <NUM> of the case <NUM>. Since the main body portion <NUM> only includes two first projections <NUM>, a different style OMT blade with an aligned or planar anchor can be positioned on the peg <NUM> in an orientation rotated <NUM> degrees relative to the OMT blade with the raised anchor. In this position, the aligned anchor can slide over the second projections <NUM> (which are smaller than the first projections <NUM>) such that the entire blade can lay flat on the lower surface <NUM> of the case <NUM>. The projections <NUM>, <NUM>, thereby, provide an option for supporting OMT blades with raised anchors or OMT blades with aligned anchors, yet still provide additional structural support between the ridges <NUM>. In some embodiments, the peg <NUM> may only include the first projections <NUM> or may only include the second projections <NUM>. In yet another embodiment, the peg <NUM> may include multiple first or second projections <NUM>, <NUM> and resting surfaces <NUM> positioned along the upward-downward direction 55U-55D such that multiple OMT blades are supported on multiple resting surfaces <NUM>.

As illustrated in <FIG>, tool case <NUM> may also receive an alternative tool holder insert <NUM>. The illustrated tool holder insert <NUM> includes a peg <NUM>, a peg retainer <NUM>, a retainer sleeve <NUM>, and a spring <NUM>. The peg <NUM> includes a tool mount portion <NUM> that is generally plus sign-shaped and extends from a main body portion <NUM> in an upper direction 55U (<FIG> and <FIG>) opposite of the downward direction 55D. The tool mount portion <NUM> may also have other shapes such an X-shape, an octagon-shape, a star-shape, or the like. The peg <NUM> also includes an insert portion <NUM> that extends from the body portion <NUM> in the downward direction 55D. The insert portion <NUM> includes a double bayonet projection <NUM> that is complementary to the double bayonet channel <NUM> of each guide <NUM> of the case <NUM>. The double bayonet projection <NUM> has substantially the same make and function as the double bayonet projection <NUM> of the peg <NUM>. Therefore, the tool holder insert <NUM> may be inserted into and supported by the guides <NUM> in the same manner as described above for the peg <NUM> (<FIG>).

Also, similar to the peg <NUM>, the tool holder insert <NUM> is configured to fit multiple OMT blades/accessories <NUM>. Specifically, the plus sign-shaped tool mount portion <NUM> is elongated to receive the second portion <NUM> of multiple OMT blades/accessories <NUM> that are stacked or placed on top of one another. In some embodiments, the tool mount portion <NUM> may receive up to four OMT blades/accessories <NUM>. In other embodiments, the tool mount portion <NUM> may include fewer or more OMT blades/accessories <NUM>. A tool support surface <NUM> extends radially from the peg <NUM> at a base <NUM> of the tool mount portion <NUM> to support the blades/accessories <NUM> when they are placed on the tool mount portion <NUM>.

With continued reference to <FIG>, the OMT blades/accessories <NUM> may be retained between the support surface <NUM> and a top portion <NUM> of the peg retainer <NUM> by a spring force from the spring <NUM>. In the illustrated embodiment, the spring <NUM> is a coil spring. In other embodiments, the tool holder insert <NUM> may include alternative or additional biasing members. The spring <NUM> is retained between a bottom side <NUM> of the support surface <NUM> and a lower portion <NUM> of the peg retainer <NUM>. The top portion <NUM> and the lower portion <NUM> of the peg retainer <NUM> are spaced apart such that the peg retainer <NUM> is U-shaped. The peg retainer <NUM> is translatable in the upward-downward direction 55U-55D and biased in the downward direction 55D to hold a number of the OMT blades/accessories <NUM> onto the plus sign-shaped tool mount portion <NUM>. The top portion <NUM> of the peg retainer <NUM> includes and open top <NUM> having a diameter D. The diameter D is large enough to allow the tool mount portion <NUM> to extend through the open top <NUM> in the upwards direction 55U, yet small enough to retain the tool support surface <NUM>.

As best illustrated in <FIG>, the lower portion <NUM> of the peg retainer <NUM> and the spring <NUM> are both housed within the retainer sleeve <NUM>. A top surface <NUM> of the retainer sleeve <NUM> lies flush with the tool support surface <NUM> and provides an additional surface for the OMT blades/accessories <NUM> to contact when being held on the peg <NUM>. The peg <NUM> and sleeve <NUM> are generally constrained from movement in upward-downward direction 55U-55D such that only the peg retainer <NUM> moves. Since the peg <NUM> and the sleeve <NUM> are constrained, the spring <NUM> provides spring force from the bottom side <NUM> of the support surface <NUM> on the stationary peg <NUM> to the lower portion <NUM> of the moveable peg retainer <NUM>. In other words, a user may pull the retainer <NUM> away from the sleeve <NUM> and the peg <NUM> in the upward direction 55U, place the second portion <NUM> of the OMT blade/accessory <NUM> onto the plus sign-shaped tool mount portion <NUM>, and release the retainer <NUM> such that the spring <NUM> pushes the retainer <NUM> in the downward direction 55D. Therefore, the top portion <NUM> of the peg retainer <NUM> is held against the OMT blade/accessory <NUM>.

<FIG> illustrate another alternative tool holder insert <NUM>. The illustrated tool holder insert <NUM> may also be received in the guides <NUM>, similarly to the peg <NUM> and the tool holder insert <NUM>. The guides <NUM> may include any of the peg <NUM> or inserts <NUM> depending on a user's preference. In other words, the guides <NUM> are "universal" in that they may receive a variety of tool holding apparatuses including the peg <NUM>, the tool holder insert <NUM> and/or the tool holder insert <NUM>.

The tool holder insert <NUM> includes a casing <NUM>, a tool retainer <NUM>, a tool support cap <NUM> and a spring <NUM>. The tool retainer <NUM> includes an upper portion <NUM> and a lower portion <NUM>. The upper portion <NUM> and the lower portion <NUM> are spaced apart such that the tool retainer <NUM> is U-shaped. The upper portion <NUM> includes a protrusion <NUM> that fits into the second portion <NUM> of the OMT blades/accessories <NUM>. In the illustrated embodiment, the protrusion <NUM> is generally plus sign-shaped, but could be have another shape, such as an X-shape. Similar to the plus sign-shaped mount portion <NUM> and the ridges <NUM>, the plus sign-shaped protrusion <NUM> receives the second portion <NUM> of the OMT blades/accessories <NUM>, which also includes a substantially X or plus sign-shape aperture for mounting to the OMT.

The casing <NUM> includes a double bayonet projection <NUM> that is complementary to the double bayonet channel <NUM> of each guide <NUM>. The double bayonet projection <NUM> has substantially the same make and function as the double bayonet projection <NUM> of the peg <NUM>. Therefore, the tool holder insert <NUM> may be inserted into and supported by the guides <NUM> in the same manner as described above for the peg <NUM> (<FIG>). The tool retainer <NUM>, cap <NUM> and spring <NUM> are housed/retained in the casing <NUM>.

The lower portion <NUM> of the retainer <NUM> extends below the casing <NUM> between a lower surface <NUM> of the casing <NUM> and the double bayonet projection <NUM>. The tool retainer <NUM> is therefore constrained along with the casing <NUM> in the upward-downward direction 55U-55D. A connecting portion <NUM> of the tool retainer <NUM> that connects the upper portion <NUM> and lower portion <NUM> fits into a first slot <NUM> of the casing <NUM> in a nesting fashion. In this way, the tool retainer <NUM> is inhibited from rotating relative to the casing <NUM>.

With continued reference to <FIG>, the spring <NUM> is compressed between the casing <NUM> and the cap <NUM> to urge the cap <NUM> in the upwards direction 55U. In the illustrated embodiment, the spring <NUM> is a coil spring. In other embodiments, the tool holder insert <NUM> may include alternative or additional biasing members. The top portion <NUM> of the retainer <NUM> extends above the cap <NUM> to inhibit the cap <NUM> from being pushed from the casing <NUM> either by a user or the spring <NUM>, for example. The cap <NUM> includes a generally flat top surface <NUM> for supporting the OMT blades/accessories <NUM>. The casing <NUM> includes a second slot <NUM> in a portion of the casing <NUM> for receiving a greater portion of the OMT blade/accessory <NUM>.

The second slot <NUM> allows space for a user to press the OMT blade/accessory <NUM> in the downward direction 55D against the cap <NUM> and against the spring <NUM> to create space between the cap <NUM> and the plus sign-shaped protrusion <NUM>. In this way, the OMT blade/accessory <NUM> is placed on the cap <NUM> between the top surface <NUM> and the protrusion <NUM>. The spring <NUM> urges the cap <NUM> toward the upper portion <NUM> of the retainer <NUM> to hold the OMT blade/accessory <NUM> on the cap and within the plus sign-shaped protrusion <NUM>.
