SKI HEEL-U
Don C. Hubbard, Auburn, Maine
Application August 24, ‘1936, Serial No. 97,611
2 Claims. (Cl. 36—35)
My present invention relates to a novel heel to
receive the heel strap of harness adapted to at
tach skis to the footwear.
The maintenance of initial adjustments of the
harness is of fundamental importance to all skiers
whether novices or experts. Ski harnesses in
clude an adjustable strap for the fore part of the
boot or like footwear and an adjustable strap
to extend around the heel of the boot. The
10 di?‘iculty of tightly adjusting such straps is com
monly appreciated and, of course, that di?iculty
is made more serious by snow and cold weather.
Skiers commonly experienced the difficulty not
only of securing an effective initial harness ad
15 justment, but also of maintaining the effective
ness of such acb'ustment while skiing. To over
- come the tendency of the heel strap to slip from
the heel, over-sized leather heels were frequently
cut down to establish a retaining ?ange. This
20 attempt to overcome this di?'iculty was not sat
isfactory as at best only the most serious conse
quences of imperfect harness adjustment were
prevented. Furthermore, the heels were not
adapted to resist the moisture and were as a con
25 sequence deformed by strap pressure, the heel
layers separated, and wear was accelerated neces
sitating relatively frequent replacement of the
heels which was expensive and generally done at
with a minimum of trimming. Centrally of the
heel seat is a ring shaped recess 4.
My heel is formed with a rigid bottom ?ange
5 of uniform thickness rearwardly of substan
tially the widest part of the heel indicated at 6, 5
6. As the sides of the heel curve to form the rear
of the heel, the width of the ?ange 5 increases
to a desired maximum width at the rear of the
heel.
The sides of the heel include outwardly curved 10
portions 1 commencing at a distance from ,the
?ange 5 proportioned to the width of the ?ange 5.
The line of origin of the outwardly curved por
tions 1 is adjacent the ?ange 5 at the widest part
6, 6 of the heel and advances towards the top 15
of the sidesv of the heel as the ?ange 5 increases
in width.
It is not essential that the line of origin of
the curved portions 1 commence ‘at the widest
part 6, 6 of the heel although that construction “0
is preferred. It is essential that the line of ori
gin of the outwardly curved portions 1 commence
adjacent the ?ange 5 and advance towards the
top of the sides to present a sufficient outward
curve to ensure the tightening of the strap 3 be- 5
fore it leaves its proper position. This con
struction also permits the use of a ?ange, which,
although adequate, still does not exceed the max
the factory.

In accordance with my invention, I provide a
novel heel which is adapted to receive the heel
ence numerals 6, 6.
The breast 8 of my heel is formed to resist
strap and to maintain the effectiveness of har
ness adjustment by tightening the heel strap as
35 it tends to work down the heel. My heel is also
formed to eliminate accumulation of snow and
accordingly reduces to a minimum the effects of
moisture. Due to economies in manufacture and
the accumulation of snow as it is beveled at
an angle of 33° to the vertical and is convexed

in use, I prefer to mold my heel of rubber.
In the drawing I have shown an embodiment
of my invention and where necessary to its clear
understanding I have suggested typical footwear
and ski harness. In the drawing:
Fig. 1 is a side view of my novel heel with
45 typical footwear and harness suggested.
Fig. 2 is a plan view of my heel, and
Fig. 3 shows my heel as viewed from ‘the bot
tom.

In Fig. 1, I have shown my heel as attached to
a boot indicated as at 2 while at 3 I have sug
gested the heel strap of a typical heel harness.
My heel is formed with a heel seat to corre
spond to the heel seat of the shoe so that my
55 heel may be attached to any footwear easily and
transversely as may be seen from a comparison ‘a,
of the drawing.

Heels incorporating my invention may be made
of any suitable material, but the full advantages
of my invention are attainable only in heels of
molded rubber. This is attributable to both the
inherent characteristics of the material used and
to the features of my invention which cooperate
to make this embodiment of my invention most
effective.

A heel made in accordance with my invention
is economical to manufacture and easily attached
to any footwear. Its snow repellent characteris
tics ensure long and satisfactory, service, while
the outwardly ?ared ?ange ensures the establish- '
ment and maintenance of the ?rm hold of the 50
harness on the footwear essential to skiers.
What I therefore ‘claim and desire to secure by
Letters Patent is:
1. A molded rubber heel for a ski boot com
prising a side wall and a strap retaining bottom 55

?ange emerging from said side wall at substan
tially the widest part of said heel and increas
ing to a desired width as the width of said heel
decreases and said side wall including a portion
outwardly curved to the edge of said ?ange, said
portion commencing at a point midway between
said ?ange and the top of said wall at the widest
part of said ?ange and receding towards said
?ange as the width of said ?ange diminishes to
10 present a gradually increased surface at the rear
of the heel to resist strap slippage.
2. A molded rubber heel for a ski boot com
prising a side wall and a strap retaining bottom
?ange emerging from said side wall at substan
tially the widest part of said heel and increasing
to a desired width as the width of said heel de
creases, the maximum width of said heel through
said ?ange being substantially equal in width to
said widest part of said heel and said side wall
including a portion outwardly curved to the edge
of said ?ange, said portion commencing at a
point midway between said ?ange and the top of
said wall at the widest part of said ?ange and
receding towards said ?ange as the width of said
?ange diminishes to present a gradually increased
surface at the rear of the heel to resist strap slip
