ADJUSTABLE FOOT RESTS
Abstract
A foot rest includes a platform for receiving a person's feet
and the platform has legs which are adjustable to vary the height
and inclination of the platform. The legs can be fixed in any
selected position by U-shaped pivotal members which engage in one
of a selected number of grooves.

Claims
We claim:
1. A foot rest comprising
a sheet-material casing open at the bottom, the top face of which
is arranged to support the user's feet,
two leg members pivoted within the interior of the casing so that
they can be pivoted independently out of the casing to selected
positions to produce various height and slope settings of the top
face,
two pivotal members, one pivoted to each said leg,
means rigid with the casing defining two sets of grooves, each said
pivotal member being engageable with a selected groove of a
corresponding said set, and
means biasing each said leg member towards the interior of the
casing so that the pivotal members cannot become dislodged from a
selected one of the respective grooves. pg,8
2. A foot rest according to claim 1 in which the top face of the
casing has a recess,
said rest further comprising
an insert member for closing the recess so as to provide an
unbroken surface for the user's feet.
3. A foot rest according to claim 1 comprising a cross-bar which
can be set to various positions on the top face of the casing.
Description
BACKGROUND OF THE INVENTION
1. Field of the invention
The invention relates to a foot rest which can be readily adjusted
for height and slope, and primarily intended for use at office
desks.
2. Summary of the Prior Art
There are some foot rests in which the rest proper is a narrow
board, which is pivoted in a tubular stirrup-shaped member and can
be set at various heights with the aid of springy pins inserted
into various holes in the tubular member. In others, a roomy
foot-board is secured by bolts between two wooden cheeks or forked
tubular members and can be adjusted for height and slope by the
loosening of two handwheels.
The disadvantage of such previously proposed foot rests is that the
height and slope adjustments are very awkward to operate and
sometimes entail considerable exertion. Ease of adjustment,
however, is a prime requirement if the best use is to be made of
them at any desk and by any person.
SUMMARY OF THE INVENTION
According to the present invention there is provided a foot rest
comprising a casing open at the bottom and made of plastics or
deep-drawn steel sheet, the top face of which is arranged to
support the user's feet said casing having two leg members pivoted
within the interior of the casing so that they can be pivoted
independently out of the casing to selected positions to produce
various height and slope settings of the top face, and means for
locking the leg members independently of one another in any one of
said selected positions. This foot rest is conducive to the
adoption of a healthy, non-tiring posture by those sitting at desks
and office machines.
BRIEF DESCRIPTION OF THE DRAWINGS
Examples of foot rests in accordance with the invention will now be
described, by way of example, with reference to the accompanying
diagrammatic drawings, in which:
FIG. 1 is a longitudinal section of a foot rest in its lowest
position, various adjustment positions being indicated in chain
lines;
FIG. 2 is a longitudinal section of the foot rest of FIG. 1
adjusted for an intermediate height;
FIG. 3 is a longitudinal section of the foot rest of FIG. 1 with
the upper surface thereof substantially horizontal;
FIG. 4 is a perspective view of the casing of the foot rest;
FIG. 5 is a perspective view of a foot rest casing with a recess
for the accommodation of the foot switch (not shown) and a cover
for closing the recess;
FIG. 6 is a side elevation of the foot rest of FIG. 1 with a
cross-bar mounted on the front edge; and
FIG. 7 is a side elevation of the foot rest of FIG. 7 with the
cross-bar in a different position.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The foot rest shown in FIGS. 1 to 7 consists of a casing 1, open at
the bottom, preferably made of plastics or deep-drawn sheet steel,
within which two support leg members, 2 and 3, are pivoted at
points 4 and 5 so that the foot ends 6 and 7 can be positioned
externally of the casing 1 independently of each other and can be
locked to give the casing 1 various heights. Locking can be
effected by U-shaped members 8 and 9, mounted at points 10 and 11
respectively, so that they can pivot in relation to the legs 2 and
3. These U-shaped members 8 and 9 can be engaged selectively in one
of a plurality of grooves 12 and 13, which are provided in parts
rigid with or integral with the casing 1. These independently
adjustable legs 2 and 3 provide a wide range of adjustment for the
casing 1, the top face of which supports the feet of the user.
The foot ends 6 and 7 are preferably made of a non-slip material
such as, for example, rubber or soft P.V.C. A return spring 18
ensures that the legs 2 and 3 are always biased towards the
interior of the casing so that the members 8 and 9 cannot disengage
of their own accord when the foot rest is in any of its set
positions. The advantages of this form of adjustment lie in its
simplicity of operation. There are no screws, locking levers,
hand-wheels or the like to manipulate; it is merely necessary to
pivot the leg concerned 2 or 3 out of the casing 1, in opposition
to the spring 18, until the associated member 8 or 9 engages in the
selected groove, and then release the leg 2 or 3.
The top face 14 of the casing 1, which serves to support the feet
of the user is preferably covered with a non-slip facing 20, made
of rubber or soft P.V.C., for example, and preferably provided with
a patterned tread, to give the user a firm grip. Moreover, the top
face 14 and its facing 20 have openings, such as slots 15, to
convey to the user's feet warmth from an optional electric heater
that can be fitted inside the casing 1.
In addition to the simple height adjustment, the foot rest
described above also offers the advantage of complete foot freedom.
That is to say that the freedom of movement of the user's feet is
unhindered by any leg members or cheeks at the sides.
For dictating machines, there are various types of foot switches,
with which the machines can be run forwards or backwards. The
shallower they are, the easier such switches are to operate. In the
case of the foot rest shown in FIG. 5, the top face 14 has been
provided with a recess 16, to accommodate a foot switch when
required.
When this foot rest is to be used without any foot switch, the
recess 16 is closed by an insert 19, as shown in FIG. 5, making the
top face 14 continuous. This insert makes the foot rest universally
applicable, irrespective of whether it is to be used with or
without a foot switch.
A cross-bar, 17, on which the arch of the user's foot or shoe can
rest (FIGS. 6 and 7), may be fitted to the top face 14 to
facilitate the operation of a foot switch, for which purpose the
cross-bar 17 serves as a fulcrum for the foot. The cross-bar 17 is
preferably adjustable, so that, in the case of wearers of low
heels, for example, it can be moved closer to the foot switch (FIG.
7). In this way, feet or shoes of different sizes can also be
brought into the most favorable position in relation to the switch.
Alternatively, in the case of wearers of very high heels, for
example, the cross-bar can be adjusted to lie right at the edge of
the foot rest, as shown in FIG. 6.
