SKI BOOT ATTACHMENT FRAME
Abstract
A device for attaching an ordinary boot to ski bindings on a ski
and for strait-jacketing such boot so it simulates a stiff ski boot
for skiing purposes is constructed as an elongate, rigid, step-in
base having a front member for securely retaining the toe of the
boot and an articulated rear member constituting a heel upper of
unstretchable material adapted to embrace the soft boot's upper
portion as a strait-jacket for skiing purposes. Such rear member
has a lower heel part and an upper ankle part pivotally
interconnected for limited back and forth articulation under
stress. Substantially unyielding strap members attached to the
upper and lower parts, respectively, of the heel upper provide for
closing the rear member and for strait-jacketing the boot following
its insertion in the device. Means are provided on the base frame
for latching cooperation with a ski binding.

Description
BACKGROUND OF THE INVENTION
Field: The invention is in the general field of ski binding devices
for attaching a skier's boots to his skis.
State of the Art: Many different kinds of ski bindings have been
developed heretofore, as well as many different kinds of ski boots.
The boots are normally sufficiently stiff to enable a skier to
manipulate his skiis by applying directive foot or lower leg
pressure to the boots as securely held to the skiis by the ski
bindings. The stiff boots are relied upon to transmit such
directive pressure to the skis substantially undiminished and
substantially without unpredictable modification. Ordinary,
relatively soft boots are comfortable, but ineffectual for the
purpose. The closest approach to permitting a skier the comfort of
soft boots, without destroying skiing effectiveness, appears to be
the provision of a molded hard and stiff outer boot split and
hinged along its longitudinal axis so as to open and close about a
special, relatively soft inner boot that can be worn during, as
well as before and after skiing.
SUMMARY OF THE INVENTION
In accordance with the present invention, most any type of soft and
comfortable boot, such as a hiking, riding, or work boot, can be
effectively used for skiing and can be worn before, during, and
after skiing, without requiring any change. Moreover, no
accessories for ski bindings need be permanently attached to the
boots, as has often been the case in the past. Instead, an
intermediate, boot attachment device is provided for temporary
attachment to the usual ski bindings in customary manner and for
step-in reception of the soft ski boot and for strait-jacketing
such soft ski boot thereafter. An elongate, rigid, step-in base has
a front member at one of its ends arranged to receive and securely
retain the toe of the boot, and an articulated rear member at the
other end constituting a heel upper of unyielding material adapted
to embrace the soft boot's upper portion as a strait-jacket for
skiing purposes. The rear member has a lower heel part and an upper
ankle part both of which are open forwardly and pivotally
interconnected for limited back and forth articulation under
stress, there being preferably a stiffly resilient interconnection
at the rear thereof providing for same. Straps of unstretchable
material, such as thin sheet stainless steel, are attached to the
upper and lower parts respectively, and are arranged to securely
buckle or otherwise close over the forward openings of such upper
and lower parts to complete the strait-jacketing of the received
boot.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT
In the preferred form illustrated, the device of the invention
comprises an elongate, rigid, step-in base 10 made up of a forward,
toe section 10a and a rearward, heel section 10b, the two sections
being separate parts of a material such as steel telescopically
interengaged by means of respective sets of longitudinal members 11
and 12 which provide for length adjustment of such base and which
are held in adjusted position as by frictional engagement.
The base 10 is provided with a front member 13 for engaging the toe
of a received boot 14 and with an articulated rear member 15
constituting a heel upper, which opens forwardly and is adapted to
close to embrace the upper of the received boot.
Rear member 15 is made of a substantially unyielding material, such
as sheet stainless steel of (.074) 14 guage, which serves to
constrict and effectively strait jacket a received boot and foot of
a skier. As shown, rear member 15 comprises a lower heel part 16
and an upper ankle part 17 articulatively interconnected by pivot
pins 18. Articulation is normally prevented, except under
conditions of great stress, by means of a stiffly resilient
interconnection at the back of such rear member 15, which
preferably comprises oppositely directed hook member 19 and 20
around which is repeatedly wrapped a length of an elastic cord 21.
The cord 21 is advantageously India rubber.
Both parts 16 and 17 of rear member 15 are open forwardly for
receiving a ski boot and are closed by means of respective straps
22 and 23 of unstretchable material, such as (.016)26 guage
stainless steel sheet, and respective buckles 24 and 25. When
closed about a received ski boot as shown in FIG. 1, the straps 22
and 23 and rear member parts 16 and 17 effectively strait jacket
the skier's foot and simulate the favored stiff ski boots that
contribute so much to ski control.
The front member 13 of base 10 is configurated to receive and
secure the toe of the ski boot, being provided in the illustrated
instance with an inturned upper lip 13a, FIG. 8, for the purpose.
Both front and rear members 13 and 15 are provided with formations,
see for example 26 and 27, FIG. 6, respectively, for engagement
with a ski binding, such as that indicated 28 in FIG. 1. Front
member 13 is also provided with inwardly projecting, sole-engaging
formations 29, FIGS. 6, 7, and 8, to provide additional securement
for the toe of the received boot.
As can be seen from FIG. 3, no special fittings are required for
the boot. Although the toe and heel portions 13 and 15 of the
device can be made to fit practically any kind of boot, it is
advantageous that these be standardized from the standpoint of
manufacture. Thus, a soft and comfortable boot can be specially
made and sold for use with the device, and it will be advantageous
that the device be made for closely fitting and special boots.
In any event, the device will become, in effect, a part of the ski
boot during skiing and will be safely released by any safety
binding for which it is adapted by proper selection of its
ski-binding-correlated construction. It should be realized that the
particular construction illustrated has been selected for
correlation with the so-called "Miller" type of ski binding
illustrated and is subject to changes required for correlation with
other types of ski bindings.
Whatever type of ski binding is used, the skier need only unbuckle
the device on each foot when he wishes to be free of his skis and
step out, leaving the devices attached to the skies by means of the
ski bindings, as shown in FIG. 2. He is no longer encumbered by
stiff and unyielding ski boots, as he is when strait jacketed for
skiing, and can walk comfortably wherever he might wish to go.
The skier can put his skis back onto his feet very easily and
conveniently by merely stepping back into the devices as still
attached to the respective skis and rebuckling the straps 22 and
23.
Whereas the invention is illustrated and described with respect to
a particular construction presently comtemplated as the best mode
of carrying it out in actual practise, it should be realized that
various changes may be made without departing from the inventive
concepts here taught and claimed.
