A FOOTGAUGE
The present invention relates to footgauges for measuring the length of a foot,
particularly but not exclusively for the purpose of determining the correct size of
footwear. The footgauges can be used to measure feet, irrespective of gender or age.
Many types of footgauge are known for foot length measurement. These
range from simple and portable manually operated devices which indicate a particular
shoe size on a printed scale to complex fixed location devices having a display screen
and motorised foot engagement plates. These known devices operate effectively but
do not address all issues regarding portability and product availability.
According to a first aspect of the present invention, there is provided a
footgauge for measuring the length of a foot, the footgauge comprising:
(i) a foot support having a foot support plate on which the underside of the foot is
placed;
(ii) a heel abutment for engaging the heel of the foot;
(iii) a toe abutment for engaging the foremost extremity of the foot;
(iv) means for receiving a touchscreen computer device;
(v) contact means for enabling the screen of the touchscreen computer device to be
contacted to indicate the length of the foot;
wherein the heel abutment and the toe abutment are movable relative to each other.
In preferred arrangements, the heel abutment is fixed relative to the foot
support and the toe abutment is movable in a linear lengthwise direction towards or
away from the heel abutment and ideally the toe abutment is resiliently biased into a
position remote from the heel abutment.
With some embodiments, the toe abutment has a downward projection which
projects through a guide slot in the foot support plate, the guide slot extending in said
linear lengthwise direction. Conveniently, the receiving means for the touchscreen
computer device comprises a support tray below the foot support plate, the width of
the support tray enabling in use the touchscreen computer device to be slidably moved
in said linear lengthwise direction with the plane of the screen being parallel with the
general plane of the foot support plate and the support tray being open at its forward
end for receiving the touchscreen computer device.
Preferably, the downward projection of the toe abutment extends downwardly
into the support tray so as to be engaged in use by the rear end of the touchscreen
computer device, rearward movement of the touchscreen computer device moving the
toe abutment rearwardly into engagement with the foot.
Usually, the foot support plate is adapted to receive a pair of feet, the heel
abutment is dimensioned to engage both heels and the toe abutment is dimensioned to
engage the forwardmost extremity of one or both feet and normally the slot is
positioned so as to be centrally positioned between the two feet when the footgauge is
in use.
It is a preferred embodiment that said contact means comprises a movable
pointer which is provided in a fixed location relative to the foot support and which is
resiliently biased away from the touchscreen computer device when in use but is
selectively movable into engagement with the screen of the touchscreen computer
device. In some arrangements the pointer is provided on a forward section which is
movable between, and securable in, a number of fixed locations relative to the foot
support. Preferably the forward section is securable by means of one or more buttons
having a push down/twist bayonet mechanism engaging in cooperating holes in the
foot support.
Preferably, the foot support includes downwardly extending support elements
for engaging a floor.
According to a second aspect of the present invention, there is provided a
footgauge arrangement comprising a footgauge as described above in conjunction
with a touchscreen computer device.
In some arrangements, the touchscreen computer device is removable from the
receiving means. Ideally, the touchscreen computer device is programmed to give a
foot length indication when the screen is contacted and preferably the touchscreen
computer device is programmed to indicate footwear availability for a foot length
indication.
Embodiments of the present invention will now be described in more detail.

measuring taking place.
In Figures 1 to 10 there is shown a footgauge 10 for use in measuring the
length of feet 11. Although the footgauge 10 is shown as being for measuring a pair
of feet 11 together it is readily possible for the footgauge to be modified for
measuring single feet individually. The footgauge 10 is to be used with a touchscreen
computer device (TCD) 12, for example an IPad™ device. Such TCDs can be
readily programmed so as to constitute with the footgauge an effective footgauge
arrangement for measuring feet 11.
The footgauge 10 comprises a foot support plate 15 having an upper surface
16 on which the undersides of the feet 11 are placed. The foot support plate 15 has at
each of its two oppositely disposed lateral edges a downwardly extending support
element 17, in this case angled, which engage the floor or other support surface (not
shown) such that the support plate 15 is somewhat raised. Alternative support
elements could, of course, be used such as a simple leg at each corner.
At the rear of the foot support plate 15 is an upstanding heel abutment 18
which in this embodiment has a slightly contoured forward facing surface 19. The
heels of the feet 11 engage the heel abutment 18 and the surface 19 is ideally
anatomically contoured so as to encourage correct positioning of the feet on the
support plate 15.
Towards the forward end of the foot support plate 15 is an upstanding toe
abutment 20 which has a central, downwardly extending projection 21. This
projection 2 1 projects downwardly through a linear slot 22 in the foot support plate 15
which slot 22 extends in a linear, longitudinal direction towards the middle of the heel
abutment 18. The slot 22 acts as a guide for the projection 2 1 such that the toe
abutment 20 can move towards and away from the heel abutment 18. The toe
abutment 20 has oppositely disposed rearward facing surfaces 23 which remain
generally parallel to the heel abutment 18 when the toe abutment 20 moves towards or
away from the heel abutment 18.
Below the foot support plate 15 is a support tray 24 for slidably receiving the
TCD 12, the support tray 24 having an open front 25. The tray 24 has a base 26
which is generally parallel to the foot support plate 15, and which is connected to the
underside of the foot support plate 15 by means of side connection walls 27. The
lateral distance between the side connection walls 27 is ideally matched to the width
of the TCD 12 so that the TCD is positioned for accurate sliding in and out through
the open front 25 of the support tray 24.
The downward projection 2 1 of the toe abutment 20 projects into the tray at 28
and can be engaged by the rear facing wall 29 of the TCD 12 when it is inserted into
the support tray 24.
At the forward end of the foot support plate there is a movable pointer button
30 which is biased upwardly away from the TCD 12 when inserted in the tray 24.
The pointer 30 has a lowermost contact point 3 1 which, when the pointer 30 is
pressed downwardly against the biasing force, engages the touchscreen 32 of the TCD
12. In the embodiment shown, the biasing action is by means of a small coil spring
33 but other biasing mechanisms would be suitable.
The moveable pointer/button 30 is mounted on a forward section 34 which is
raised from the foot support plate 15. This forward section also acts as an abutment
which limits the possible forward movement of the toe abutment 20. Although not
shown, the toe abutment 20 is resiliently biased towards the forward section 34, that
is away from the heel abutment. This position is clearly shown in Figure 1. The
biasing action of the toe abutment can easily be achieved by means of springs or other
suitable devices/mechanisms.
The abutment of the toe abutment 20 with the forward section 34 effectively
sets a datum with regard to the foot measuring process in that the distance between
the toe and heel abutments is known.
The use of the footgauge arrangement is shown clearly in Figures 2 to 5. The
feet 11 to be measured are placed on the upper surface 16 of the foot support plate 15,
preferably with the person standing on the footgauge 11. The rear of each foot 11 is
placed against the forward facing surface 19 of the heel abutment 18 with the feet 11
on either side of the linear slot 22. This position is shown in Figure 2 with the TCD
12 about to be inserted into its support tray 24 through its open front 25.
The TCD 12 is slidably moved in a rearward, longitudinal direction until its
rear facing wall 29 engages the part 28 of the downward projection 2 1 of the toe
abutment 20. The TCD 12 is moved further in said rearward, longitudinal direction
and this causes the toe abutment 20 to move rearwardly towards the heel abutment 18
until the rearward facing surfaces 23 engage the forwardmost point or points of the
feet 11. Ideally (but not essentially), the weight of the TCD 12 and friction with the
support tray 24 are sufficient to overcome the biasing force which acts to return the
toe abutment 20 into its forwardmost position such that the toe abutment 20 remains
in position against the feet 11 without manual assistance.
Once the toe abutment 20 is in contact with the feet 11, the movable
pointer/button 30 can be pressed against the force of the spring 33 such that the
lowermost contact point 3 1 engages the screen 32 of the TCD 12 so as to register a
suitable activating contact therewith, as shown in Figure 4. The pointer/button 30 is
then released to return to its rest position.
Figure 5 gives a simple illustration of the TCD 12 indicating the correct size of
the feet 11. Once the size has been registered, the TCD 12 can be removed from its
support tray 24 and the toe abutment 20 returns to its forwardmost position by means
of the stated biasing action.
The TCD 12 is adapted to incorporate a real-size foot measuring scale
programme on its touchscreen 32 so as to display (on activation of the pointer/button
30) a certain, largest size when the TCD 12 abuts the downward projection 2 1 when
the toe abutment 20 is at its forwardmost location against the fixed forward section 34
of the foot support plate 15 because the maximum distance between the heel and toe
abutments is known. When the TCD 12 is inserted further and the toe abutment 20
moves rearwardly, the location of the pointer/button 30 effectively moves relative to
the scale on the touchscreen 32 of the TCD 12, indicative of a different, i.e. smaller,
shoe size which is displayed when the pointer/button 30 is pressed against the screen
32.
The TCD 12 can be linked to a stock control system (not shown) so that the
sales assistant will immediately know what particular styles of footwear are in stock
for the particular footsize measured. The stock control system can also incorporate
images of the styles so that the customer can select those which are of interest so that
they can be tried on. The TCD 1 may incorporate this stock control system or it can
communicate, ideally via a wireless network, with a central computer which hosts the
stock control system.
With some footwear ranges, the width or girth of the feet 11 can also be
measured separately and this information can be inputted via a suitable programme
shown on the touchscreen. This additional measurement enables a better fit for the
footwear, especially children's footwear, but of course may have an effect on stock
availability.
The stock control system could also be operative to enable out of stock
footwear to be ordered for later delivery to a store or for delivery to the customer's
home. Other modifications can, of course, be linked to the TCD 12 which was
originally used to measure the foot size of the customer.
The above described footgauge arrangement has a fixed heel abutment and a
fixed pointer, with the toe abutment and the TCD being movable together in order to
measure the foot. However, it will be readily appreciated that other alternatives are
possible. For example, the heel abutment and the TCD could be in fixed locations
with the toe abutment, incorporating the pointer, being movable towards and away
from the heel abutment. In further alternatives, the heel and toe abutments could be
movable with the pointer fixed to one of them and the TCD moving with the other.
In the above described arrangement, the pointer 30 is provided on the forward
section 34 which has a fixed location relative to the foot support plate 15. The range
of foot lengths which can be measured is somewhat dependent on the length of the
TCD screen 32. In the arrangement shown in figures 11 to 14, the forward section 34
is not permanently fixed to the foot support plate 15 but is movable in the lengthwise
direction between two set locations defined by the cooperating pairs of holes 60, 6 1 in
the foot support plate 15. One pair of holes 60 is located nearer the heel abutment 18
than the other pair 61. The forward section 34 can be moved between the two
positions and fixed in one of the two positions against movement in the lengthwise
direction. The toe abutment 20 is still movable away from the forward section 34
towards the heel abutment 18 when urged by the TCD and is again resiliently biased
forwards into abutment with the forward section when the TCD is removed.
The two positions (or more if desired) of the forward section enable different
datum points for measuring foot length, perhaps for children and for adults. The
choices of position can be incorporated into the program or 'app' loaded onto the
TCD, with the user inputting which of the two forward section positions has been
used so as to ensure correct size information is provided when the pointer is pressed.
In the particular arrangement illustrated, the forward section 34 is mounted for
sliding movement in the lengthways direction of the footgauge and on each side is
provided with a rotatable button 70. Each button 70 is spring loaded in an upward
direction by means of a captured coil spring 7 1 and each button 70 has a lowermost
projection 72 and an upper grip flange 73. A known bayonet mechanism (not shown)
enables each button 70 to rotate through a quarter turn with a push down and twist
operation which moves and retains the projection 72 into raised or lowered positions.
The projections 72 can only take up their lowered positions when aligned with one of
the pairs of holes 60, 6 1 in the support plate 15 (figures 11 and 12). When the
projections 72 are raised, then the forward section 34 can slide so as to align the
projections 72 with one pair of the holes 60, 6 1 (figures 13 and 14). When the
projections 72 are engaged in the holes, the forward section is effectively fixed with
respect to the foot support plate and the toe abutment 20 can then be moved away
from the forward section 34 to measure the feet in the manner described above in
connection with figures 1 to 10.
It will be appreciated that more than two locations can be provided for the
forward section 34 combined with suitable program modification for the TCD. Also,
the mechanism for locating the forward section 34 against movement relative to the
foot support plate 15 in use is just an example of a suitable mechanism.
In figures 15 to 19 there is shown an alternative footgauge 110 for use in
measuring feet. Ideally, the footgauge 110 is folded from paperboard or another sheet
material having sufficient rigidity for the purpose. Conveniently, the footgauge 110 is
intended for home use rather than in-store use, the consumer either collecting the
footgauge 110 as a flat-pack in store or receiving the flat-pack by post/courier. In
some embodiments, and as illustrated in figures 15 to 19 the footgauge 110 is similar
in form to a file having front and rear covers 111, 112 linked by folds to a central
spine 113.
The rear cover 112 may incorporate instructions 114 and/or a sheet for
recording the growth of a child's foot. Upstanding from the fold junction of the rear
cover 112 and the central spine 113 is a wall 115 which is perpendicular to the floor
when the footgauge file is folded out as shown in the figures. One or more fold-up
reinforcement panels may be provided behind the wall 115 so that the wall can be
braced in its upright position relative to the spine 113 in use. The height of the wall
115 is less than the width of the spine so that when the footgauge file is closed the
wall 115 does not interfere with the front cover 111. The wall incorporates a length
of paperboard 116 which is fixed at a central location 117. The ends 118 of the length
of paperboard 116 slide inwardly towards the central location and lock in place using
suitable interlocking formations (not shown) so as to provide a generally C-shaped (in
plan view) heel abutment 119 for receiving the rear of the foot to be measured.
Forwardly of the heel abutment 119, the front cover 111, which
effectively constitutes a foot support plate, incorporates two pieces of board 120, 121
which are slightly upstanding so as to constitute a pair of parallel guide rails 122
which are perpendicular to the fold between the front cover 111 and the spine 113. A
series of paperboard bridge members 123 are provided in channels 124 in the front
cover 111. Each bridge member 123 has one end secured beneath the first piece of
board 120 but is slidably located beneath the second piece of board 121 . Each bridge
member 123 has a series of transverse folds 125 and a finger tab 126 remote from its
fixed end. Each bridge member 123 can be manipulated by a sliding/lifting action so
as to form a rectangular bridge 127 over the surface between the guide rails 122. This
is shown clearly in figure 12. In use, only one bridge member 123 is to be raised at a
time, depending on the length of the foot being measured, the bridge members 123
being provided at increasing distances from the heel abutment 119. Each bridge
member has a central hole 128 and the purpose of this will be discussed later.
A support block 130 is provided for receiving a touchscreen computer device
(TCD) 131. In this particular embodiment the TCD 131 is in the form of a smart
phone having a touchscreen 136. The support block 130 can be folded from a flat
sheet of paperboard and provides a toe abutment 132 and a box section tray 133 with
a central depression 134 and floor 135 for receiving snugly the TCD. The size of the
depression may be changeable by means of folds or shaped inserts for example so as
to accommodate a variety of sizes of TCD. Generally the height of the box section
tray 133 is slightly greater than the thickness of the TCD and is about the same as the
height of each bridge 127. The width of the box section enables it to be slidably
received between the guide rails 122 for guided movement towards and away from
the heel abutment 119.
With one of the bridges 127 raised, as shown in figure 17, the box section tray
133 can be slidably inserted below the bridge 127, the sliding action towards and
away from the heel abutment being guided by the parallel guide rails 122. The TCD
is then inserted into its position in the tray 133 such that the screen 136 of the TCD
moves longitudinally beneath the hole 128 of the bridge.
Figure 18 shows the footgauge 110 in use although no foot is shown. The foot
to be measured is placed on the footgauge 110 with the heel of the foot against the
heel abutment 119. The foot measurement should be made with the user's weight on
the foot with the footgauge 110 ideally opened out on to the floor. Each bridge
member 123 is associated with a range of overlapping foot sizes so the appropriate
bridge member 123 is raised according to a rough estimate, perhaps indicated in the
instructions 114. The support block 130 with the TCD is then moved towards the foot
until the endmost toe is engaged by the toe abutment 132. The measurer then places a
finger over the hole 128 and flexes the bridge 127 downwardly so as to contact the
screen 136 of the TCD. The TCD 131 then gives a foot length indication on the
screen.
The TCD 131 incorporates a program or 'app' that effectively measures the
distance from the hole 128 to the toe abutment and this is coupled to the known
distance from the hole 128 to the heel abutment 119. All the user needs to do is to
input which bridge member 123 is being used so that the correct hole 128/heel
abutment 119 distance is used in the calculation. The other TCD features discussed
above in relation to the first embodiment of figures 1 to 10 are equally applicable to
the alternative embodiments. Similarly, the TCD 131 need not be a phone but could
also be a larger, 'tablet' type device having a touchscreen.
It will also be appreciated that the precise design and materials of manufacture
of the footgauge can be modified whilst remaining within the scope of the
accompanying claims.
