Patented Sept. 27, 1938 ‘ 2,131,283 UNITEDIS'TATVES PATENT OFFICE j - 2,131,233 I‘ " 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. imum Width of the heel designated by the refer- '30 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 30 40 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. 50 - 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. *0 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. 6 ' 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 2 2,131,283 ?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 page.
