Description
BACKGROUND OF THE INVENTION
In my co-pending United States Patent Applications, Ser. No.
726,094, filed May 2, 1968, now U.S. Pat. No. 3,521,385, entitled
"Ski Boot," and Ser. No. 8,547, filed Feb. 4, 1970, entitled "Inner
Boot and Method for Forming the Same," a boot is described that is
custom fit to the foot of an individual. The boot includes an outer
liner, and an inner liner connected to the outer liner and spaced
apart therefrom to form a substantially sealed compartment between
the liners. When the individual's foot is positioned within the
boot a liquid resin elastomer reaction mixture is injected into the
compartment between the liners. The reaction mixture is cured in
situ between the liners of the inner boot to form a resilient mold
which positions the inner liner substantially adjacent to and
around the foot of the individual and the outer liner is positioned
adjacent to the interior sidewalls of an outer boot support shell.
Because of the development of the herein described boot a need has
arisen for apparatus suitable for injecting a resin elastomer
mixture into the inner boot and thereafter curing the reaction
mixture insitu.
BRIEF DESCRIPTION OF THE INVENTION
In its broadest form the invention comprises a support platform
sized to support a boot for an individual's foot; a reservoir for
containing a liquid material attached to the support platform;
conduit means connected to and in communication with the reservoir
for exhausting liquid material out of the reservoir and into the
boot connected to the conduit means; and means connected to the
reservoir for urging liquid material to flow out of the reservoir
and into the conduit means.
In another embodiment of the invention, heating means are secured
to the support platform for heating the environment surrounding a
boot supported on the platform to accelerate curing of reaction
mixture injected into the boot.
In still another embodiment of the invention upwardly extending
support members are affixed to the platform for supporting an
individual in an upright position while the individual is being fit
with the boot.
In yet another embodiment of the invention clamping means are
affixed to the support platform for fixedly positioning the boot to
the support platform while the boot is being filled with a reaction
mixture.
In still yet another embodiment of the invention a housing is
mounted on a support platform for substantially enclosing the boot
supported on the platform.

DESCRIPTION OF THE PREFERRED EMBODIMENT
In the drawings there is shown a support platform 10 sized to
support a pair of boots 12 thereon in a spaced relationship. The
boots are fixed to platform 10 with back-tie-down-plate 14, fixedly
secured to platform 10, and front-tie-down-plate 16, adjustably
secured to platform 10 with bolts 18 sized to extend through
parallel elongated slots 20 formed in the front plate. Plates 14
and 16 are provided with recesses 22 sized and shaped to receive a
portion of either the front or rear end of a boot 12 to hold the
boot against end-wide movement. By using tie down structure of the
type herein described and illustrated boots 12 are fixedly secured
to support platform 10 for filling while being easily releasable
therefrom by loosening bolts 18 and sliding plate 16 back away from
the toe ends of the boots 12.
A housing is secured to platform 10 and mounted thereover for
supporting reaction mixture reservoir 24 and its associated pumping
structure, hereinafter described, and for substantially enclosing
boots 12 so that the temperature of the environment surrounding the
boots can be altered to accelerate reaction mixture curing.
Preferably, the housing is a two piece structure which includes
three-sided rear section 26 covered with top sheet 28 having a port
30 positioned therein sized to receive the back portion of an
individual's legs when an individual is standing on platform 10 in
boots 12. A removable front section 32, preferably constructed from
a transparent material such as a heat resistant plastic, is mounted
on platform 10 which mates with back section 26 to substantially
enclose the area above the platform surrounding boots 12. Like
section 26, front section 32 is also provided with a port 34 sized
to receive the front portion of an individual's legs. As indicated,
a reservoir is mounted on the top covering 28 of rear section 26.
Preferably the reservoir is a cylindrical member 24 having a
removable bottom end 25 for cleaning purposes and an open opposite
end. Discharge tubes 34 and 36 are secured to bottom end 25 in
communication with the reservoir's interior for discharging
material out of the reservoir. Ports 38 and 40 are positioned in
top covering 28 to accomodate discharge tubes 34 and 36. Flexible
tubes 42, preferably formed from an easily cutable material such as
a soft plastic, are removably attached to the open ends of
discharge tube 34 and 36 for passing reaction material into boots
12 as described in my above noted patent.
Reaction material is urged out of the reservoir through the
discharge tubes connected thereto with piston 34 which is snugly
received within the reservoir. When the reservoir is a cylinder 24,
piston 44 is a cylindrical disk-like member. The piston is urged
into cylinder 24 with screw 46 which is threaded in harness 48
which in turn is secured at its opposite ends to brackets 50
affixed to plate 28. A handle 52 can be attached to the end of
screw 46 to aid in turning the screw. Harness 48 is firstly used to
provide a support frame for screw 46 and secondly, it holds
reservoir 24 in a fixed position on plate 28. The opposite ends 52
of harness 48 are turned inwardly towards each other and are sized
to slide under the outwardly turned ends 54 of brackets 50.
Accordingly, harness 48 can be easily removed by merely loosening
screw 56 and thereafter rotating the harness until its ends are
positioned away from brackets 50.
When an individual is being custom fit with boots 12, it is
preferred that the individual stand in a generally upright
outwardly position. Accordingly, an upwardly extending support
structure can be secured to platform 12 which provides a framework
for the individual to lean upon. Also, it is desirable to elevate
platform 10 above floor level 56 for ease in using the apparatus of
the invention. As shown in FIG. 1 and 5 support members 56 and 60
are attached to platform 10, preferably proximate the corners of
said platform when it is a rectangular shaped member, for holding
the platform at said elevated position. In addition, poles 58 aid
in supporting frame members 62 which can be used to support a
person's body in an upright outwardly extending position.
Preferably, cross bars 64 and 66 are adjustably secured to frame
members 62 at a poxition proximate the thighs and chest of the
individual standing in the apparatus. The cross bars can be secured
in an adjustable fashion in a variety of ways such as through the
use of outwardly extending pins 68 sized to support cross bar 66 or
pins 65 which are sized to pass through frames 62 and cross bar
64.
Preferably, heating elements 70 are mounted to platform 10, as
shown in FIG. 6, adjacent to the sides of boots 12. The elements
are powered in a conventional fashion from an electrical power
source. Control means such as potentiometer 72 and on-off switch 74
can be provided in the power circuit.
To aid in mounting and dismounting platform 10 a step 76 can be
secured to the platform. As shown in FIGS. 1-3 step 76 is secured
to poles 58 and frame members 62 proximate the front end of the
platform.
In using the apparatus of the invention front housing section 32 is
removed from platform 10 so that a person wearing boots 12 adapted
to be custom fit to his feet, can step onto the platform 10 from
step 76 and then position the rear portion of his legs within the
opening 30 formed in the top late 28 of rear section 26. While in
this position, boots 12 are locked to platform 10 with tie-down
plates 14 and 16. Reservoir 24 is then positioned on the top plate
28 such that tubes 34 and 36 pass through ports 38 and 40
respectively. Thereafter, flexible connector tubes 42 are connected
between tubes 34 and 36 and the boots 12. A liquid reaction mixture
27 is then poured into reservoir 24 and piston 44 is slid into the
open end of the cylinder 24 until it contacts the liquid reaction
mixture 27 contained therein. Finally, harness 48 is secured over
reservoir 24 and screw 46 is turned until it contacts piston 44. At
this time, the boot is ready to be filled with liquid reaction
mixture. This is accomplished by turning screw 46 which urges
piston 44 to slide into reservoir 24 and thereby urge reaction
mixture 27 to exhaust through tubes 34 and 36 into boots 12. When
the boots are filled with liquid material to the desired pressure,
front housing section 32 is placed on platform 10 over boots 12 and
heating elements 70 are activated by closing control switch 74
thereby heating the environment surrounding the boots to a desired
temperature. After a predetermined time, the reaction mixture, cure
hardens insitu in the boots. When this occurs, heater 70 is turned
off, front section 32 is removed from support platform 10, and
tubes 42 are cut thereby allowing the individual fitted with the
boots 12 to step away from platform 10.
