[0001] This invention relates to a foot rest by which a user's feet may be raised off the
ground, preferably at an angle to the ground and, in particular, to a foot rest which
is, at least in part, inflatable.
[0002] In the past, foot rests have been formed from a relatively rigid frame work on which
softer material which may be provided, usually with some form of cushioning to support
the feet. Alternatively, foot rests take the form of a pillow or cushion and are in,
general, deformable. A further type of known support is a rigid structure which, at
least in part, is hinged so that it can be partially collapsed when not in use.
[0003] However, none of the known foot rests are sufficiently light and compact when carried
for it to be practical to transport them on a long journey such as a train, bus or
aircraft journey. In particular, they are cumbersome and take up significant amounts
of room in hand luggage which is typically carried on such journeys.
[0004] Inflatable foot rests are known, but they are generally impractical, bulky and of
a substantially wedge or truncated wedge shape and therefore provide no support to
the back of a user's foot.
[0005] When travelling in a train, bus or aircraft, it is usual for the seats to be arranged
in rows and most known foot rests are too big to fit underneath the row of seats in
front of a user and therefore they cannot be used on such journeys.
[0006] It is an aim of the present invention to provide a foot rest which is compact, cheap
to manufacture and which overcomes the above problems.
[0007] According to the present invention, there is provided an inflatable foot support
comprising:
a front bolster for supporting, in use, the forefoot portion of a user's foot;
a rear bolster for supporting, in use, the back of a user's heel; and
an intermediate bolster between the front and the rear bolster for supporting, in
use, the underside of a user's heel,
wherein the top of the rear bolster is, when in use, higher than the intermediate
bolster.
[0008] Thus, the present invention provides a device which, when the user wishes to utilise
it, can be very quickly and easily inflated to provide the required, relatively rigid,
and small size support. Furthermore, by providing a rear bolster which is higher than
the intermediate bolster, the present invention ensures that a user's heel has sufficient
support to be raised off the ground and that a user's foot is prevented from slipping
rearwardly.
[0009] There may be a plurality of intermediate bolsters and, in which case, the rear bolster
is preferably higher, in use, than the rearmost intermediate bolster.
[0010] Preferably the foot support is formed from two sheets of plastic material which are
heat sealed together. In one arrangement, some parts of the foot support may have
a non-slip surface such that when it is in contact, in use, with the floor or with
a user's foot, the foot support or the foot is prevented from slipping. Alternatively,
one or both of the sheets of plastic material may be formed from a non-slip surface,
such as a flocked plastic.
[0011] The front and/or the rear bolster may be formed from one or more chambers which are
rolled or folded over themselves and fixed, in use, in place.
[0012] Preferably, the front and/or the rear bolster are formed by three interconnected
chambers which, when inflated, form a substantially triangular shape. In this configuration,
it is found that, when a user's heel is placed on to the intermediate bolster, the
rear bolster is raised further, thereby by providing firm support to the heel and
substantially increasing the rigidity and stability of the support.
[0013] The front and/or the rear bolster may be formed by two interconnected chambers such
that, when inflated, one lies substantially in the same plane as the at least one
intermediate bolster and the other chamber forms an inverted U-shape transverse to
the plane.
[0014] Preferably, the foot support comprises support means for retaining, in use, the rear
bolster at an angle with respect to the at least one intermediate bolster.
[0015] The support means may be provided by one or more web portions extending between the
rear bolster and at least one of the intermediate and front bolsters. The web portion(s)
is preferably heat sealed to the rear bolster and to the intermediate bolster. Alternatively
or additionally, the support may be provided by the substantially triangular shape
of the rear bolster.
[0016] Preferably the front and/or rear bolster is formed by heat sealing one edge of a
chamber to another edge of a chamber.
[0017] The fixing means may be carried out by one of velcro ®, poppers or a zip.
[0018] The foot support preferably comprises an air inlet to enable the foot support to
be inflated and deflated.
[0019] The intermediate bolster and the chambers of the front and rear bolsters preferably
define internal volumes that are in communication with each other and with the air
inlet.
[0020] The front, rear and intermediate bolsters are preferably substantially parallel with
each other.
[0021] The front bolster and the intermediate bolster may have an oval cross section having
a longer dimension and a shorter dimension.
[0022] It would also be possible for the cross section of each of the front, intermediate
and rear bolsters to be oval, with the front bolster being higher than the rear bolster
which is higher than the intermediate bolster.
[0023] Examples of the present invention will now be described with reference to the accompanying
drawings, in which:
Figure 1 is a side view through one example of the present invention;
Figure 2 is a plan view of the foot support of Figure 1;
Figure 3 is a side view of another example of the present invention;
Figure 4 is a plan view of the foot support of Figure 3;
Figure 5 is a front view of the foot support of Figure 4;
Figure 6 is a schematic cross sectional view along A-A from Figure 5; and
Figure 7 is a schematic cross sectional view of a further example.
[0024] A foot support 20 is shown in Figure 1 and includes a front bolster 11, a rear bolster
12 and an intermediate bolster 13. In the example shown, a single intermediate bolster
13 is shown, although it is envisaged that more than one intermediate bolster 13,
if appropriately sized, could be used. The foot support 20 is formed from two sheets
14, 15 of plastics material which are heat sealed together along heat seals 16.
[0025] Two supports 17, in the form of webs, extend between the rear bolster 12 and the
intermediate bolster 13 and retain the rear bolster 12 at an angle with respect to
the intermediate bolster 13.
[0026] Thus, when in use, and as shown in dotted line, a user's shoe, or foot, rests on
the foot support 20 as shown. The forefoot portion of the foot rests on the upper
surface of front bolster 11, the underside of the heel rests on the upper surface
of the intermediate bolster 13 and the rear of the heel rests against the rear bolster
12. The support means 17 ensures that the rear bolster 12 maintains its inclined position
to provide sufficient support to the user's heel.
[0027] As can be seen in Figure 2, the rear bolster 12 is provided with recess portions
18, formed by holes through the bolster, the holes being heat sealed around the edges.
Alternatively, the recess portions 18 may be formed simply by heat sealing the lower
sheet 14 and upper sheet 15 together. The recessed portions 18 are intended to receive
the rear of a user's heel and also help to reduce the thickness of the rear bolster.
[0028] The front 11, rear 12 and intermediate 13 bolsters are substantially parallel to
each other and, to define each bolster relative to its adjacent bolster, heat seal
portions 19 are formed between adjacent bolsters, leaving a gap 22 for the passage
of air between bolsters.
[0029] The upper and lower portions of the front 11 and intermediate 13 bolsters are optionally
provided, for example by glueing or heat sealing, with non-slip material 21 such that,
in use, the portions on the lower surfaces contact the ground and the portions on
the upper surface contact a user's foot to prevent slipping.
[0030] A further example of a foot support 30 is shown in Figures 3 to 6.
[0031] The rear bolster 12 is formed from three chambers 31, 32, 33 which are arranged such
that chambers 32, 33 are folded over chamber 31. In this example, chamber 33 is heat
sealed or glued at the joint between the intermediate bolster 13 and chamber 31. However,
it is possible that this fixing could be carried out by mechanical means, such as
velcro, poppers or a zip.
[0032] In this arrangement, the support for chamber 33 is provided by chamber 31, 32 which,
together with chamber 33, form a substantially triangular support. Additional heat
seal portions 34 ensure that chambers 31, 32, 33 take up the correct shape, when inflated.
In this example, the foot support 30 is also formed by two sheets of plastics material
and, as shown in Figure 3, the lower sheet 14 is formed from a flocked plastic which
will also form the outer surface of the rear bolster 12, although it could, of course,
be a normal plastics material as used in the upper surface.
[0033] As can be seen in Figure 4, the chambers forming the rear bolster 12 are shaped so
as to minimise the material used in the foot support and to reduce the volume which
is to be inflated. An air inlet 35 is shown on the upper surface of the front bolster
11, although the inlet could be provided at an alternative location in the foot support.
Again the upper surface of the front bolster is provided with a portion 21 which is
non-slip material and this could also be provided on the upper surface of the intermediate
bolster 13.
[0034] Figure 5 shows a front view of the front bolster 11 indicating one possible position
for the air inlet 35. Although not shown, it is envisaged that a cover may be provided
for the air inlet to prevent it becoming dirty. The cover could be held in place by
any suitable temporary fixing means.
[0035] Figure 6 shows a cross sectional view along A-A from Figure 4 and indicates one possible
direction of air flow through the foot support 30.
[0036] Figure 7 shows a cross sectional view of a further example in which the front bolster
11 is formed from three chambers 41, 42, 43 which are arranged such that chambers
42, 43 are folded over chamber 41, in the manner described above in relation to the
rear bolster 12. In this example, the chamber 43 is larger than chambers 41, 42, thereby
resulting in the front bolster 11 providing a higher support than in the example in
Figures 3 to 6. This is particularly advantageous as it increases the angle at which
a user's feet are supported and improves the comfort of that support.
