United States Patent 3,447,812 DEVICE FOR BINDING THE HEEL PART OF A SKI SHOE Koji Kato, 14-Go, 12-Ban, Higashi-Ogu 4-choxne, Arakawa-ku, Tokyo, Japan Filed July 26, 1967, Ser. No. 656,098 Int. Cl. A63c 9/00 US. Cl. 280-11.35 4 Claims ABSTRACT OF THE DISCLOSURE The present invention relates to a device for binding the heel part of a ski shoe, and elements thereof, and more particularly, to a metalfixture for fitting the boot easily in its entirely to the ski by binding its heel part.

The object of this invention is to provide a step-in type heel binding device for a ski shoe which can fix and retain effectively and suitably the heel part of a shoe to the ski with extreme ease and smoothness and which is adapted so as to be capable to adjust the mounting position of the boot and also the compression position for the heel part of the boot.

The present invention will be better and further understood and other advantages of the invention will become apparent from the following description of one embodiment of the invention and in connection with the appended drawing, in which:

FIG. 1 is a side view of the embodiment of the invention;

FIG. 2 is a side View thereof wherein an upper frame is shown in vertical section;

FIG. 3 is a plan view thereof;

FIG. 4 is a plan view thereof wherein the upper frame is shown in cross-section; and

FIG. 5 is a frontal view thereof.

Referring to the drawing, there is provided a carrier plate 3 which is engaged in rails 2 formed by bending both sides of a base plate 1; an engaging channel 4 is provided at the lower end of said carrier plate 3 between frame plates 3'; an anchoring pin 7 provided with an auxiliary frame 6 having a bent wall part 5 is engaged in said engaging channel 4; a lever handle provided with a fitting pin 8 and a receiving pin 9 located between the frame plates 3' of the carrier plate 3 is pivotally supported by pin 11; there is provided a coil spring 12 obliquely anchored and connected between the receiving pin 9 and the anchoring pin 7. There are provided a heel receptacle 1'4 and a heel presser on one side of an upper frame 13; said heel presser 15 is adapted so as to be vertically adjustable; a plastic body 16 such as hard nylon or the like is held on the upper face and the inside of said upper frame 13; and further there is provided an anchoring block 18, with a fitting channel 17, pivotally supported at pin 19; the upper frame proper 20 thus formed is pivotally supported at pin 21 together with the carrier plate 3 in conformity with the frame plates 3 of said carrier plate 3. There is constituted a bent wall part 22 at the end of the base plate 1; said bent wall part 22 and the bent wall part 5 of the auxiliary frame 6 are connected through an adjusting screw 24 having a left screw thread 23 on one end and a right screw thread 23' on the other.

In the drawing, numeral 25 denotes screw holes; nu-

meral 26 denotes a stop screw; numeral 27 denotes a nut; numeral 28 denotes a slot; numeral 29 denotes a hook; numeral 30 denotes an adjusting nut firmly fitted to the adjusting screw 24; numeral 31 denotes a nut for fixing the adjusting screw 24; and numeral 32 denotes a window part for swinging the lever handle 10.

Such being the composition of the embodiment of this invention, the operation thereof will now be given as follows:

In the first place, the device is securely fixed with screws to a specified position of the ski, whereafter the lever handle 10 is pushed down as is shown in chain dotted lines in FIG. 2. When the fitting pin 8 of the lever handle 10 is released from the anchoring block 18 and the upper frame proper 20 is turned, the lower end of the anchoring block 18 will abut the fitting pin 8 and said upper frame proper 20 will face upward and come to be set in the position as is shown in chain dotted lines in FIG- URES 1 and 2. The heel of the boot is then mounted on the heel receptacle 14 provided on one side of said upper frame proper 20, which receptacle is thence depressed, and the curved part 18' of the anchoring block 18 will push the lever handle 10 down through its action on the fitting pin 8. The upper frame proper 20, thereupon, will turn so that the heel presser 15 comes to press against the rear part of the boot so that the same is smoothly and securely fixed to the ski. At the same time, the fitting channel 17 of the anchoring block 18 will come to receive the fitting pin 8, and the lever handle 10 will be in tension constantly by virtue of the coil spring 12 obliquely connected and anchored between the anchoring pin 7 and the receiving pin 9, so that it is so adapted that the normal fitting condition of the anchoring block 18 with the fitting pin 8 is invariably maintained. Composed in this manner, the boot may be perfectly fixed and retained on the ski, in addition to the fact that there is not the slightest fear of disengagement of the anchoring block 18 with the fitting pin 8 even though there occur vertical, horizontal or other vibration or shocks during ski running, so that skiing can be enjoyed comfortably and with security.

Further, the heel presser 15 for the boot is devised so that it can be vertically adjusted against the upper frame proper 20 by means of the stop screw 26, and therefore, it is shiftable to any position suitable to a boot of any size, thereby making it possible to fix the boot to the ski under the optimal condition. On the other hand, the adjusting screw 24 which connects the bent wall part 22 of the base plate 1 with the auxiliary frame 6 can be rotated by the adjusting nut 29; the carrier plate 3 may be shifted and set through the auxiliary frame 6 up to any point suitable to the users boot, and consequently, the boot may be optimally fixed and held. As the present device is so composed that the adjusting screw 24 is provided with the left screw 23 and the right screw 23' so as to be constituted in different shapes on both ends of the screw and the adjustable shifting range of the carrier plate 3 is extremely large, said carrier plate 3 can be moved and adjusted to the size of the boot and thus can be set at any point in conformity with the boot, and therefore the device may be used regardless of the size of boots.

When the ski boot is to be removed, this is achieved by downwardly depressing the end of the lever handle 10 between the frame plates 3' of the carrier plate 3 with the tip of a ski stock or by hand; disengaging the fitting of the anchoring block 18 provided with the upper frame proper 20 with the fitting pin 8 of the lever handle 10; and thereafter, just simply turning the upper frame proper 20.

As described in the foregoing, the present invention is extremely advantageous and meritorious in comparison to the conventional means, especially, of reliably fixing and holding the ski boot to the ski, and smoothly and rapidly effecting the fixing as well as removing the boot.

What I claim is:

1. A device for binding the heel part of a ski boot, said device comprising a base plate adapted for being secured to a ski and having bent ends forming rails, a carrier plate slidably engaged in said rails and including a frame plate having a channel, an anchoring pin engaged in said channel, an auxiliary frame secured to said pin, a lever pivotably mounted on the carrier plate and including a fitting pin and a receiving pin thereon, a coil spring secured to said anchoring pin and said receiving pin the position of the latter pins being such that the spring has an inclined position, an upper frame member pivotally supported from said carrier plate for movement between a raised unlocked position and a lowered locked position, a heel receptacle and a heel presser secured to said upper frame, an anchor block carried by said upper frame and having a channel for receiving the fitting pin on said lever when the upper frame is in its lowered locked position, and means between said base plate and auxiliary frame for connecting the same to gether with adjustment whereby the position of the upper frame and thereby of the heel receptacle and heel presser relative to the base plate.

2. A device as claimed in claim 1 wherein said means between the base plate and auxiliary frame comprises an adjustment screw including first and second threaded portions of opposite hand respectively engaged in said base plate and anchoring frame.

3. A device as claimed in claim 1 wherein said anchor block includes a lower curved portion which abuts against said fitting pin in the raised position of the car-' References Cited UNITED STATES PATENTS 3,125,349 3/1964 Schweizer 280-11.35 3,317,217 5/1967 Poiger 280-1135 3,278,195 10/1966 Salomon 280-1135 3,333,859 8/1967 Smolka et al 280-1135 3,366,394 1/1968 Shimizu 2801l.35
