TOE GUARD FOR WALKING CAST, SHORT LEG CAST & LONG LEG CAST
Abstract
The toe guard incorporates an elongated mounting stem adjustably
engageable with the walking tip of a foot cast. The forward end of
the stem is rigidly affixed to the central portion of a rearwardly
directed arcuate protective bar which encircles the toes and
forward portion of the cast in generally spaced overlying relation
to the stem itself.

Claims
We claim:
1. In a walking cast, a cast body, a depending walking tip and a
toe guard, said tip including an enlarged head portion embedded
within the body with the tip projecting therebelow, said guard
including an elongated stem positioned along the lower portion of
the cast and engaged with the walking tip, said stem including a
forward end portion forward of said cast, said guard further
including an arcuate generally horizontal protective bar, said bar
having the central portion thereof rigidly affixed to the forward
end of said stem with the bar projecting rearwardly from the
forward end of said stem in spaced overlying relation to said stem
and in partially encircling relation to the forward end of said
cast to provide a protective enclosure therefor.
2. The cast of claim 1 wherein said toe guard stem projects through
and is frictionally engaged by the walking tip below the head
portion thereof.
3. The cast of claim 1 wherein said stem is positioned in engaging
overlying relation to said walking tip head portion and embedded
within the body of the cast.
4. The cast of claim 1 wherein said stem, and hence said guard, is
longitudinally adjustable relative to the length of the cast.
Description
The present invention generally relates to foot casts, and is more
specifically directed to a unique toe guard mountable on the cast
in a manner so as to project forwardly thereof and provide a
protective enclosure for the normally exposed toe area of the
foot.
It is a primary object of the invention to provide a structurally
simple yet highly effective protective device for use in
conjunction with a foot cast in order to provide a protective guard
for the toes while at the same time maintaining the desired
exposure thereof.
Another significant object of the instant invention is to provide a
toe guard which mounts on the rubber walking tip with the mounting
thereof being such so as to enable a positional adjustment of the
guard for the accommodation of variations in the cast or foot
size.
Basically, the guard includes an arcuate protective bar which
horizontally encircles the toe area and a mounting stem rigid with
the central portion of the protective bar. The stem extends
rearwardly from the central portion of the protective bar into
spaced underlying relation thereto for engagement with the cast for
a mounting of the guard.
These together with other objects and advantages which will become
subsequently apparent reside in the details of construction and
operation as more fully hereinafter described and claimed,
reference being had to the accompanying drawings forming a part
hereof, wherein like numerals refer to like parts throughout, and
in which:
FIG. 1 is a bottom plan view of the guard mounted on the walking
tip;
FIG. 2 is an enlarged cross-sectional view taken substantially on a
plane passing along line 2--2 in FIG. 1, the walking tip being
shown in section and the guard being shown in elevation;
FIG. 3 is a cross-sectional detail taken substantially on a plane
passing along line 3--3 in FIG. 2; and
FIG. 4 is a sectional detail illustrating a variation in the
orientation of the guard mounting stem relative to the walking
tip.
Referring now more specifically to the drawings, reference numeral
10 is used to generally designate the toe guard comprising the
instant invention. The foot cast with which the guard 10 is to be
associated has been designated by reference numeral 12 with the
walking tip indicated by reference numeral 14. This tip 14, as is
conventional, includes an enlarged elongated head portion 16 which
is embedded within and locks the tip 14 to the lower portion of the
cast 12.
The toe guard 10 includes an arcuate protective bar 18 designed so
as to encircle and lie closely adjacent both the exposed toes 20
and the forward end of the cast 12. In order to do so, it will be
noted that the bar 18 includes a relatively straight side portion
which generally parallels the inner portion of the foot and a
slightly outwardly flaring second side which generally parallels
the outer portion of the foot.
An elongated mounting stem 22 has the forward end thereof rigidly
affixed to the central portion of the protective bar 18, this
forward portion of the stem 22 being upwardly turned so as to lie
generally in the plane of the protective bar 18 at the point of
engagement therewith.
The stem 22, along the length thereof, slopes downwardly and
rearwardly relative to the forward end thereof so as to underlie
the toe area in spaced relation thereto and generally follow the
slight curvature of the bottom of the cast 12. With reference to
FIGS. 2 and 3 in particular, the stem 22 can be frictionally
engaged through the walking tip 14 below the cast-embedded head
portion 16 thereof with the frictional engagement of the stem 22
through the tip 14 being such so as to substantially rigidly
position the stem 22, and hence the toe guard 10, while at the same
time allowing for a slight longitudinal adjustment thereof through
a physical manipulation of the guard. The general curvature of the
stem 22 which positions the protective bar 18 in overlying spaced
relation thereto will tend to preclude any accidental longitudinal
shifting of the guard 10 should the protective bar come in contact
with an obstacle in that force applied to the bar 18 will not
provide such a direct load on the stem as to cause a shifting
thereof through the tip. Thus, the protective enclosing of the toes
20 will be maintained notwithstanding the fact that the stem 22,
and particularly the central portion thereof which may be straight,
is adjustable through the tip 14.
FIG. 4 illustrates a slight variation in that the stem 22 has been
mounted in overlying relation to the cast-embedded head portion 16
of the walking tip 14. If so desired, the head portion 16 can
include a central depression or recess for the accommodation of the
stem 22. In this form, the adjustment of the guard 10 will normally
be effected prior to a complete hardening of the cast 12 in that
the stem 22 will conceivably be locked into position by the cast
plaster.
As indicated in FIGS. 1 and 3, the toe guard 10 will preferably be
formed of a rigid or slightly resilient metal coated with a
suitable protective plastic or other elastomeric material.
The foregoing is considered as illustrative only of the principles
of the invention. Further, since numerous modifications and changes
will readily occur to those skilled in the art, it is not desired
to limit the invention to the exact construction and operation
shown and described, and accordingly all suitable modifications and
equivalents may be resorted to, falling within the scope of the
invention.
