A43b 5 /04 U.S. Cl. 36-2.5 6 Claims ABSTRACT OF THE DISCLOSURE A plastic ski boot of rugged characteristics accomplished by providing the pivoting gaiter with a trunnion pocket and the buckles thereof with a Spanner plate.
This invention relates generally to ski boots and more particularly relates to improvements in the ruggedness and performance of plastic ski boots. The use of plastic in ski boots has many remarkable advantages. One of the principal advantages of plastic ski boots is their general rigidity which leads to a iine edge control by the skier. Pivoted gaiters have been provided to permit a forward flexing of the skiers legs while preserving the sought-after rigidity. One principal objective of this in vention is to provide an improved pivoting joint between the outer shell of the boot and the gaiter through the use of a trunnion pocket in the outer shell.
More specifically, an important objective of this invention is to provide a pair of trunnion pockets in the sidewall of the outer shell of the boot which pockets receive the lower portions of a pivoted gaiter and having the openings of said pockets disposed below the upper, inner edge of the outer shell such that water, slush, snow, or other contaminants will not seep into the interior of the boot because of the pivoted joint.
As is recognized by students of the art, the ski boot is the principal connection between the skier and the ski. The more perfect this union, the better the control of the ski. In view of this, there have been many ingenious buckles provided for insuring that the ski boot is snugly fitted to the foot of the wearer. Because of the great strain which must be absorbed by the buckle, it is important that all tendencies for the buckle to tear from the mounting be eliminated. Another principal objective of this invention is to provide a mounting for a buckle which reinforces the outer shell in such a manner that tear-out or rupture is virtually eliminated.
A further objective of this invention is to provide a plastic ski boot having an outer shell of novel and unique design which pivotally receives a gaiter at an improved pivot position and includes means for mounting a buckle thereon at a distance removed from the pocket in a manner to eliminate the tearing of the sidewalls themselves.
A further objective of this invention is to provide an improved sole reinforcement -member which leans the skier forwardly while having a sufiicient dimension at the greatest area of stress.
These and other objects of the invention will become more apparent to those skilled in the art by reference to the following detailed description when viewed in light of the accompanying drawings, wherein:
FIGURE l is a side elevation;
FIGURE 2 is an exploded elevation view of the invention;
FIGURE 3 is a cross-sectional view along the line 3-3 of FIGURE l;
FIGURE 4 is a longitudinal sectional View of the boot sole section;
FIGURE 5 is an enlarged plan view of a buckle assembl 5FIGURE `6 is a cross sectional view along the line 6--6 of FIGURE 5;
FIGURE 6a is a cross sectional of double Spanner embodiment; and
FIGURE 7 is a partial perspective view of the buckle shown in FIGURE 6.
Referring now more particularly to the drawings wherein like numerals indicate like parts, the numeral 10 indicates the boot of this invention. The boot includes an outer shell 12, an inner thermoplastic shell 14, a U- shaped gaiter 16, a plurality of buckle members 17 and a sole portion 20.
Within the sole section 20 is a wedge-shaped reinforcing and filler block 22 embedded and secured to the outer shell 12 by a bed of epoxy resin 24. The slant on the upper surface 26 of the wedge-shaped block comfortably leans the skier and supports him in a front leaning position.
Extending upwardly from the sole section 20 is the foot-receiving portion or outer shell 12 having two front flap portions 28 which define an opening 32 toward the toe of the boot. Trunnion pockets 34 are formed along the sides of shell 12 just below the ankle bone of the wearer. Only one pocket 34 and its associated parts will be described, it being understood that a corresponding trunnion pocket is formed (but not shown) in the shell portion away from the teader in FIGURE 1. The pocket opening edges 36 are spaced a distance below the upper edges of the outer surface of the shell. The pockets have semi-circular bottoms 38 and the opening edges 36 slant toward the heel of the boot. Since the inner surfaces or panels 39 of the trunnion pockets extend above the outer panels thereof (above edges 36), any snow, water, ice or diit that becomes lodged in the pockets 34, will not enter the interior of the boot but rather will seep to the rear.
The gaiters 16 are formed with semi-circular lower hinge portions 42 and 44 which are respectively received in the trunnion pockets. The pockets are adapted to receive these lower hinge portions and to permit the forward pivoting action of the gaiter member. Each of the hinge members is pivotally secured to the outer shell by way of rivet studs 46. The studs extend through either side of the pockets 34 and as seen in FIGURE 3, through the inner shell 14. Such an arrangement provides a very stable pivot trunnion between the members.
The gaiter member 16 and the upper shell 12 are firmly secured to the leg of the wearer by drawing the side flaps 28 and the gaiter member together. Quick release buckles have been found very suitable for these purposes. The above-mentioned pocket trunnion concept provides a connection between the gaiter and the main boot of great strength. An improved buckle retention means is disclosed in FIGURES 5-7 which retains this strength for the entire boot. A triangular Spanner plate S5 is secured to the interior surfaces of the boot by a plurality of rivets 50, 52, and 54. The rivet 54 is formed with an upright rod 56 which has a transverse threaded opening 58 therethrough. The opening 58 receives a threaded Shaft y60 which is formed with a journal 62 at its outer end. The journal is cylindrical in shape and has openings at either end thereof to receive the ends of a flexible springsteel securing loop 70. The locking members which cooperate with these boots are of the multiple screw lever type more fully described in United States Patent 3,363,288 issued Ian. 16, 1968.
A double Spanner arrangement is shown in FIGURE 6a wherein an upper spanner 57 cooperates with the inner spanner 55 to grasp the flap 38 therebetween.
As it is well known to the art, individual shapes and configurations of the foot vary widely between individuals. In the cited patent an improved buckle having coarse and fine adjustments is disclosed. By utilizing flexible loops of the type described herein a still further means of adjustment is available via a simple replacement of loops of different lengths.
In a general manner, ywhile there has been disclosed in the above description, what is deemed to ybe practical and efficient embodiments of the invention, it should be Well understood that the invention is not limited to such enibodirnents as there might be changes made in the arrangement, disposition, and form of the parts without departing from the principle of the present invention.
