TOOL SET WITH INTERSPERSED DUAL STANDARD ELEMENTS
Cross-Reference to Related Application
100011 This application claims the benefit of U.S. Provisional Application
No.: 62/915,694,
filed October 16, 2019, which is hereby incorporated by reference in their
entirety.
Field of the invention
100021 This relates to tools, and more particularly to sets of tools having a
range of different
sizes.
Background of the Invention
100031 Tools such as Allen wrenches are typically arranged in sets having a
sequence of
different standard sizes. These sets are typically in a single format or
standard, such as matric
or fractional inch. Users will generally require two sets, and these sets
segregate the tools of
one format from tools of the other format.
100041 Many fasteners do not provide an indication of what size, format or
standard they are.
A user with an unknown fastener may make a visual estimation of the size of
the fastener, and
that test a tool. If that is not a fit, the user selects a larger or smaller
tool as needed.
100051 While effective, this presents problems when there are two formats of
fastener
configurations that are not visually evident. In some instances, when the user
is attempting to
use the wrong tool set format, such as fraction tools for a metric fastener,
the use will find after
testing multiple tools that none is a fit ¨ all are too large or too small.
This indicates that the
wrong set is being used, and the user repeats the size selection process with
the other format
set. This is an annoyance and inconvenience.
100061 A greater risk is that for some tool and fastener sizes, there will be
workable but
incorrect tool fits. The wrong format tool will be close enough to that of the
right format tool
that a user may be deceived into thinking it is a correct fit, and never
realize that other format
set should be used. With the slightly incorrect fit, the tool or fastener may
be damaged by the
use.
100071 Accordingly, there is need for a tool kit with a first set of tools of
a first standard and
of different sizes, a second set of tools of a different second standard and
of different sizes, and
a holder adapted to receive the first and second set of tools intermixed with
each other in an
integrated sequence arranged according to size irrespective of standard. The
different standards

may be indicated by different colors or other indicia, or by positions, such
as offset rows that
preserve the sequence.

Detailed Description
[0023] Figure 1 shows an Allen Wrench set 10 including a holder block 12
defining a sequence
of passages 14 or graduated sizes in a row arranged by size. The apertures are
each sized to
removably retain an Allen wrench of a selected size.
[0024] A first set of wrenches 20 is a set of a range of different sizes of a
first dimensional
format or standard, such as Metric, with the wrenches having sizes designated
in millimeters.
2
CA 03155058 2022-4-15
WO 2021/076172
PCT/US2020/014583
[0025] A second set of wrenches 22 is a set of a range of different sizes of a
second dimensional
format or standard, such as fractional inch, with the wrenches having sizes
designated in
fractional inches.
[0026] The first set 20 is shown in black and the second set 22 is shown in
white as indicia to
identity the standard Of format associated with each wrench. This indicia may
be any visible
marking, coloring, or plating, or any attachment such as a handle with a shape
color, texture or
other indicia to indicate the associated standard or format. The block may
also have indicia of
the dimensional specification of each tool associated with each aperture to
assist in replacing
loose wrenches in position. In some embodiments, no indicia is needed as the
user does not
care what is the format of the correct wrench, only that the correct wrench is
readily and
accurately identified and used.
[0027] The wrenches are arranged in sequence by their actual size. For
illustration, a limited
number of wrenches are shown. Allen wrench sets of metric and fractional
standards may
typically have the following sizes, arranged in interspersed, integrated, and
numerical sequence
by actual size regardless of standard:
metric fractional decimal
(mm) (in) (in) % larger
0.05 0.0500
1.5 0.0591 18.1%

100281 The first column represents the metric wrenches of set 20, and the
second column
represents the wrenches of set 22. These do not necessarily alternate, and
there are occasions
in which wrenches of the same standard are adjacent in sequence. There are
other occasions
where wrenches of different standards are very nearly the same, such as the
5/6e inch and
2mm wrenches, and their 2x and 4x multiples 5/32, 5/16 and 4mm and 8mm_ These
essential
equivalents differ from their matches by only 0.8%, which is believed to be
within the tolerance
of fastener hex socket dimensions. If there is a concern about a no-go misfit
for fasteners with
socket sizes at the lower limit of tolerances, the slightly smaller fractional
inch nominal size
may be used. In these instances, economy, compactness, and lighter weight may
be achieved
by omitting the duplicative ones, and the user seeing a suitable size will
naturally select the
suitable size even if not officially of the same standard as the fastener.
Some tool designs have
a greater tolerance for size differences, and these may optionally be
employed.
100291 With the exclusion of duplicate tools, it may be useful to mark the
tool or the holder at
the tool's location with indicia for both compatible sizes (e.g. "5164 2mm")
just as all other
tools or locations may be marked with the actual single tool size. The
effective duplicated size
(e.g. 2mm) may be indicated on labeling or packaging parenthetically to
indicate the capability
but to avoid creating consumer confusion about the number of tools present.
100301 The user will normally select a wrench that appears to be the correct
size for a fastener,
and if too small test larger sizes until the largest one that still fits is
found - for female tools
like sockets and box wrenches the smallest that fits is selected. In any case
the tightest fit is
preferred. By sequencing the tools by size, the user need not wonder if they
could achieve a
tighter and more correct fit in a wrench set of the other standard, nor does
the user who tests
and finds the tightest of each standard needed to qualitatively estimate which
is actually the
tighter fit. With the illustrated embodiment it is readily established which
is the tightest fit by
the one that still fits and is one size smaller than ¨ adjacent in the
sequence to - the smallest
one that does not fit.
100311 Figure 2 shows an alternative storage block 30 in which the graduated-
size apertures
that receive the tools are arranged in size sequence along the length of the
block, but in rows
that are offset from each other. The spaces 32 for metric tools are in a first
row 34, and the
spaces 36 for fractional tools are in a second row 40 offset from the first.
This is analogous to
4
CA 03155058 2022-4-15
WO 2021/076172
PCT/US2020/014583
black keys and white keys on a piano keyboard that are arranged sequentially
by pitch but with
offset striking surfaces.
[0032] The offset rows are only one example of how the storage black may
indicate the format
or standard of the wrenches without disrupting the size sequence and
integrated and
interspersed quality. Alternatives include having each region associated with
a standard in a
color, texture or other quality that is distinguished from the other
standard's region. This
quality may be associated with the distinctive indicia of each set of
wrenches, such as having
a darker block region associated with the wrenches of a standard that is
indicated by plating or
coating of a darker color. This facilitates the returning of tools to their
proper apertures,
especially when tools of different standards may be very similar in size. An
alternative or
additional indicator of the different standard region is elevating one portion
to a different level.
In simpler embodiments, the tools may be arranged in a straight line, with
printed indicia
indicating the tool size to be received at a location.
[0033] Figure 2 further shows a top view along the length of the tool passages
showing how
the two rows are arranged. Each row has a different position along the Y axis
indicated, while
each hole of each row has a unique position along the X axis. The X axis may
be considered
the main "path" or "sequence" or "arrangement" for purposes of arranging the
tools by size
irrespective of format. This path is shown as a straight line, but may be
curved or in a circle,
such as when tools may be displayed or held in a rotating turret on a CNC
machine, or in a
rotating desktop base or stand such as Bergeon watchmakers screwdrivers are
displayed. The
position along the X axis (or path in general) is the critical position that
determines a tool's
location by size. Each tool is located in one direction along the X axis from
smaller tools, and
in the other direction from larger tools. All the tools smaller than a given
tool are located on
one direction away from the tool, and all the larger tools are located in the
other direction.
[0034] The provision of separate rows along the main path for each format of
tools is optional
for embodiments in which users benefit from knowing which format of tool they
are using.
This may be employed along with different color or other indicia on the tools
to aid replacement
in the holder. Such a feature (by location, or color, or both) may be an aid
for instances in
which the users knows the format of a fastener, so they can have better
prospects for a correct
first guess at tool size, or fewer tools to test for correct size. Whether the
tools are arranged
along a path with a single or multiple rows, the position along the path (that
is, the X axis in
CA 03155058 2022-4-15
WO 2021/076172
PCT/US2020/014583
the illustrated embodiment) is the important factor in determining where tools
of a given size
are positioned relative to each other.
[0035] Figure 3 shows a compact Allen wrench set 50 with wrenches attached to
a handle 52
and having a folding capability. This is a conventional format and structure
for single standard
wrench sets but is assembled with the wrenches of two different standard
formats 54, 56
integrated according to the principles of the invention. The wrenches or
handle may be
provided text markers 60 indicating size, and the wrenches are optionally
colored or provided
with visual indicia to indicate their standard format.
[0036] The use of indicia for standard indication is useful not only for
replacing tools in a
proper location ¨ not a concern in this embodiment in which tools are captured
with loop ends
receiving pivot pins 62 on the handle, but also for users who know what format
their project or
fastener requires and can avoid testing tools of the wrong format.
[0037] Figure 4 shows a socket tool kit 70 having a first set 72 of metric
sockets of a first color
arranged on a first line 74, and a second set 76 of fractional sockets
arranged in a second line
80 offset from the first line 76. As with other embodiments, the sockets are
provided with
indicia to indicate their standard format. The sockets are held in a housing
or tray 82 defining
apertures 84 in the illustrated arranged, and the apertures are sized to
closely receive only the
correct size socket. Tools of any type that come in sizes, such as box
wrenches and drill bits
may be fabricated and housed according to these principles. In alternative
embodiments, the
sockets may be arranged in a single line without different rows also
indicating format. The X
axis geometric relationships along a path discussed with respect to Figure 2
are applicable to
this and other embodiments.
[0038] Figure 5 shows a tool set 100 with a block 102 having a single row of
holes sized to
receive the set of tools 104 of both formats, arranged by functional
dimension, i.e. their caliper
thickness based on the hex head socket they are sized for. This illustrates
the typical
appearance of the graduated lengths of the tools, as is common in single
format sets. While
tool lengths need not be mathematically proportionate as a precise
mathematical function of
length based on the caliber or effective size, the graduated length provides a
visual and intuitive
confirmation that tools are in the right apertures, as the tool tips terminate
in a curved line 106.
In the illustrated example, the tool ends are in a straight line even as the
upper ends are offset
due to the L shapes nesting. This straight line may be curved, and preferably
have a smooth or
continuous shape without steps, and most preferably with no instances in which
a smaller
6
CA 03155058 2022-4-15
WO 2021/076172
PCT/US2020/014583
caliber tool has an actually longer or apparently longer length as seated in
the holder. While
tools are normally made with length proportional or relatively related to
girth, thickness, or
caliber, when combining existing sets of formats, often existing components
used by
manufacturer do not provide a smooth appearing pattern, because there has
previously been no
motivation to ensure that each metric tool appears to be a length between the
lengths of the two
inch tools that surround it in a sequence based on too width. In the preferred
embodiment with
tools of different lengths, the tool length or tool tip position when stowed
(preferably both) is
based on the functional size of the tool so that when arranged or stored by
size as disclosed, all
the (smaller caliber) tools in one direction from a given tool are shorter
than the given tool, and
all the (larger caliber) tools in the other each tool are longer.
[0039] For these purposes, tool length can also mean the length that protrudes
from the block,
or the relative distance of protrusion of tool tips, even if overall length is
affected by the L-
shape nesting discussed above.
[0040] For tools that serve in each format (such as 5/64 and 2mm being
essentially the same
size) special appearance features or indicia may be provided, such as coating
or coloring only
one portion of the tool as associated with one format and with another portion
in the other
visual condition associated with the other format. This may include having one
of more faces
of the six sides in one color while the others are in the other color. It may
also be achieved by
having one end of the tool with one appearance and the other with the other
appearance. If
only a single indicia is used for a tool serving in both formats, that may
preferably be selected
to reflect the dominant or primary format in the jurisdiction in which the
tool is expected to be
used (e.g. inch for US, Metric for Europe). A selected tool 110 is shown with
visual coating
characteristics or indicia common to each different format's appearance, in
this example it
alternates lengths of the darker colorations associates with the fractional
tools, and the lighter
colorations associated with the metric tools, in a striped appearance
indicating compatibility
with both of the respective formats.
[0041] Existing tool sets and holders for L-shaped wrenches of a single format
often have two
straight path segments for compactness, as Fig 5 is illustrated one straight
row for clarity and
simplicity, with another straight row potentially being occupied by a series
of tools all larger
than the largest in the illustrated row. In this example, some existing
products have essentially
a single path broken into two segments, as opposed to embodiments of the
invention that
illustrate a single path along an X axis with separate rows for each format,
but dimensionally
7
CA 03155058 2022-4-15
WO 2021/076172
PCT/US2020/014583
arranged along the X axis. Each path segment preferably has its own linear or
smooth length
slope or curve. The largest tool of the path segment of smaller tools will
normally have a
shorter actual length than the smallest of the row of larger tools. Note that
when referring to
size in this application, all references to size (caliber, girth, width, big,
small) are specifically
to the tools' width and not length. Length is specifically indicated where
intended.
[0042] Where tools are arranged in straight rows, as elsewhere, the indicia
showing the
intended tool size is provided at each storage position. Even a holder without
tools may be
provided according to an embodiment of the invention with indicia indicating
the
dimensionally integrated tool set to be stored. A set such as of socket tools
with an unmarked
holder with an array of evenly spaced 3/8" square posts for holding sockets is
considered to
have the indicia even by the presence of how the sockets are initially
installed.
[0043] Like the Fig 3 folding tool, a folding tool 200 is shown in Figure 6,
and also has the
same proportional length tool elements, with the lengths of each element from
the pivot 62
being based on its functional size. In some embodiments like this in which
there is no need to
identify smaller and larger tools for reinstallation in a separate block, the
tools may be of the
same apparently length, or nearly the same. In this embodiment, a slight
gradation of length
suits tool manufacturing, and the format of the Z-block housing. A selected
tool 202 serving
duplicate metric and inch functions is shown in another format to call
attention to its function,
with an end portion of the tool having the surface appearance of one format,
and the rest having
the appearance of the other. The Fig 6 illustration is shown with alternating
tool formats for
illustrative purposes, but in most actual applications there may be adjacent
pairs of one type or
the other based on actual dimensions.
[0044] Figure 7 shows a socket tool set 300 with a socket holder bar 302
having movable
socket holder clips 304 slidably mounted to the bar and with square socket
bosses 306
protruding toward one face or the other of the bar. All of the bosses for
supporting inch sockets
310 extend to one side, and all those for supporting metric sockets 312 face
the opposite
direction. The clips are arranged in a sequence based on the actual dimension
of the socket to
be received. Each clip is marked with an indicia indicating the socket
dimension to be received.
Thus, the metric and inch clips are interspersed. In this embodiment, the
clips are narrower
than many of the sockets, and in some instances are economical with space by
remaining
adjacent on each side. In alternative embodiments in which the holder has only
one side or
when otherwise preferred, all clips would be sequenced by size indicia (the
actual dimension)
8
CA 03155058 2022-4-15
WO 2021/076172
PCT/US2020/014583
so that the matching mounted sockets would be arranged by size even if facing
the same
direction, and potentially with no indication of the format, only an
arrangement by size.
[0045] In addition, because users may have existing tool sets of both formats,
there may be a
need for storage blocks or cases that simply arrange existing tools in a more
convenient way.
These storage facilities may include bench blocks designed to rest on a
workbench, tool holders
of the types illustrated above but without the tools included, and any other
type of tool storage
facility having a position or location sized, shaped, or arranged to accept a
certain tool size,
including trays with sized compartments, and bins with dividers creating a
pocket for each tool.
[0046] Figure 8 shows a top view of an Allen key tool holder 400 related to
that of Figure 1,
with the two formats laid out in rows, with the inch tools in a straight row,
and the metric tools
of intermediate size positioned in a second row. There are fewer of the metric
tools, and each
aperture is arranged in an equilateral triangle with equal wall webs
separating the metric hole
from each of the two adjacent inch holes as the spacing of the holes in each
row. For the
smaller sized the web thickness is about 0.065 inch, and the web is about
0.075 for the larger
holes and tools in this range up to 5mm. Fig 9, 10, and 11 show a side view of
the same tool
holder, including a flat inside the hole for retaining the tool with the point
edge of the tool
against the flat.
[0047] Fig 12 and 13 show a companion holder 450 for the larger Allen tools of
7/32 to lOrnm
size.
[0048] Fig 14 shows a tool holder 500 with the inch tools 510 extending above
a sloped upper
surface 512 in a row, and the metric tools 520 extending above a higher sloped
surface 522tha1
is stepped above the inch tool slope for improved visibility. Their relative
positions along the
X axis are based on their size as in other embodiments, with the level
providing an indicator of
format.
100491 Fig 15 shows an alternative tool set 600 that is a simple variation on
the tool set of
Figure 5. It has a holder block 602 with a single straight row of holes for
receiving the Allen
wrenches 604 in sequence based on size.
100501 In this example, the wrenches range in size from 0.050 to 5nun, for a
typical small
household or consumer set
100511 The individual wrenches are identified by number and letter according
to the following:
100521 0.05" 610A

[0064] 5 mm 610M
100651 The 2mm and 4mm sizes that might be included in some embodiments are
excluded in
this example because of the adjacent fractional sizes that are 0.8% smaller.
[0066] As is true in all the above embodiments, each of the wrenches is
located in position
along the main path based on not only its size relative to the wrenches of its
own format or
standard, as is the case for most wrench sets, but based on the size of the
wrenches in the other
standard.
100671 For example, the 2.5inm metric wrench 610F is located adjacent to and
immediately
between fractional wrenches 610E (3/32") and 610G(7/64"). This relationship
applies whether
the wrenches are in a single line as shown, or in staggered adjacent lanes of
a multi-row
sequence as shown in Figure 8 and other embodiments. In the main linear
dimension that forms
the path or axis along which the tools are arranged, each tool is positioned
based not only on
the size of tools in its own format, but based on tools of the other format
that is intermingled
in the sequence. The 7/64" tool 610G is likewise positioned between the 2.5mm
wrench 610F
and the 3nurt wrench 61011.
[0068] The 1/8" tool is positioned like all others between the tool of the
next larger size (9/64"
6103) and next smaller size (3mrn 610H) illustrating that each tool is
positioned in sequence
based on size irrespective of the format of the next larger and next smaller
tool.
[0069] Not shown is a version for Hex bits in which a convention grid box with
a
compartment for each hex bit is populated with hex bits in size sequence
without segregating
inch bits from metric bits. These may be arranged sequentially in rows as one
would read.

Printed or molded indicia may assist with replacement, and instead of box-like
compartments,
the receptacles may be sized to closely receive the dimensional working end of
each bit to
force the bits to be replaced in the correct spaces. This may be achieved by
connecting a
socket head screw of the right size into a base so that each bit resides in
the type of screw it is
sized to drive. More preferably, a molded plastic replicates this effect. The
preferred
embodiment may be considered as a tool kit with a first set of tools of a
first standard and of
different sizes, a second set of tools of a different second standard and of
different sizes, a
holder adapted to receive the first and second set of tools intermixed with
each other in an
integrated sequence arranged according to size irrespective of standard.
