7 i 11? H1 ANDERSON CCH/LD/NG 7% WMQ ATTORNEY United States Patent 3,003,777 SKI BINDING Anderson C. Hilding, 421 36th Ave. E, Duluth, Minn. Filed Apr. 25, 1960, Ser. No. 24,487 11 Claims. (Cl. 28011.35)

My invention relates generally to skiing equipment and, more particularly, to a binding, a portion of which is mounted on the ski with a complementary portion mounted on the boot which removably secures the ski boot to the ski. More specifically, my invention relates to an improvement in a binding having a construction which is particularly adaptable to cross-country skiing, and which is an improvement on the disclosure in my Patent No. 2,649,306.

Conventional ski bindings which may be used for crosscountry skiing do not allow proper movement of the foot and ankle relative to the ski and the same are diificult to connect to and disconnect from the ski.

It is, therefore, an object of my invention to provide a ski binding which allows the desired movement of the foot relative to the ski in a, more or less, natural walking movement. It is a further object to provide a ski binding which allows easy and positive connection of the boot with the ski and easy release of the boot from the ski. With my invention, the connecting and disconnecting of the boot and ski may be done simply by the skier without bending over, by a simple manipulation of a portion of the binding by means of a ski pole. While my binding is particularly adapted for cross-country use, it may be used for slope skiing, as well.

It is also an object to provide a ski binding which substantially prevents snow from accumulating under the toe of the boot.

I shall not here attempt to set forth and indicate all of the various objects and advantages incident to my invention, but other objects and advantages will be referred to in or else will become apparent from that which follows.

The invention will appear more clearly from the following detailed description when taken in connection with the accompanying drawings, showing by way of examples preferred embodiments of the inventive idea wherein like numerals refer to like parts throughout.

FIGURE 13 is a sectional view on the line 13-13 of FIGURE 11.

FIGURE 14 is a section through the base plate and the forward engaging portion of the boot plate in disengaged position.

Referring to the drawings in detail, my binding A includes the boot plate 16 which is formed of the flat body portion 18 having the relatively narrow rear portion 20 which terminates in the widened front portion 22. Extending outwardly and upwardly from the front portion 22 by means of the extension portions 21 and 23 are the spaced connector lugs 24 and 26. The connector lugs 24 and 26 are identical, each being formed of a substantially semi-circular collar portion 28 defining a slot or opening 30 formed therein having substantially parallel surfaces. The openings 30 are disposed to the body portions 18 at an angle of approximately 45. The inner surface of the collar forms a bearing for the shaft hereinafter men tioned. The boot plate 16 is connected to the sole of the boot B by means of screws positioned in the holes 32 with the connector lugs 24 and 26 at the front edge of the sole of the boot, FIGURES 2, 3 and 4.

Further provided is the ski plate member 34 including the flat base portion 36 secured to the upper face of the ski C by the screws 38. Formed integral with and extending upwardly from the base 36 are the spaced flanges 39 and 40. The flanges 39 and 40 rotatably support the shaft 42 at the ends thereof. The shaft 42 has formed thereon the parallel, spaced and flat areas 44 and 46 adjacent one end of the shaft and the identical areas formed adjacent the opposite end of the shaft. The areas 44 and 46 form a flattened area 47 on the shaft 42.

The numeral 48 designates a lever which is secured to an outer end of the shaft 42 and which is used to rotate and secure the shaft as hereinafter explained. The thickness of the shaft material between the surfaces 44 and 46 form a flattened area 47 on the shaft 42. width of the opening 30.

Further provided is the spring clip 50 secured to the ski C in line with the lever 48 and adapted to receive the lever 48 and hold the same in a lowered position, such as illustrated in FIGURES l and 4, to maintain said flattened areas 47 out of register with said slots 30.

The boot B is connected to the ski plate 34 by holding the boot substantially in the raised position shown in FIG- URES 2 and 3 with the spaced flattened portions 47 of the shaft 42 in line with the openings 30 of the connector lugs 24 and 26. The boot is then moved forwardly and downwardly so that the lugs 24 and 26 engage the pair of spaced flattened portions 47 and further moved so that the shaft 42 is within the lugs. The lever 48 is then moved forwardly to the position of FIGURES 1 and 4, thereby moving the flattened portions 47 out of alignment with the openings 30. The lever 48 is held in the forward position by engaging the same with the clip 50 secured to the ski C.

In the event it is desired to firmly secure the boot to the ski for slope skiing, I provide, in addition, the heel plate 52 formed of the flat base portion 54 and the up standing rear flange portion 56. The flange portion 56 has formed therein the depression 58 which receives the hook end 69 of the spring urged clamp 62 mounted on the shaft 64 pivotally connected at its lower end to the lugs 66 secured to the ski. The heel plate 52 is secured by screws inserted through the holes 68. The clamp 62 has the ring portion 70 which may be easily engaged by a ski pole for releasing the hook 60 or placing the hook 60 on the flange 56.

In FIGURE 9 is illustrated a further embodiment of the invention wherein is found the ski plate 72 which ineludes the base plate flange portion 74, and extending upwardly and angularly therefrom is the support portion 76 terminating in the tubular bearing formation 78. Extending downwardly and angularly from the tubular bearing formation 78 is the support portion 80 which terminates in the flange portion 82- The plate 72 is secured at its flanges 74 and 82 to the ski D by means of the screws 84.

The tubular bearing formation 78 is formed with the spaced openings 86 and 88. Further provided is the shaft 90 which is substantially identical to the shaft 42 of FIG- URES l-4. The shaft 9% is rotatably mounted in the tubular bearing portion 78 and has formed thereon the spaced flattened areas 92 and 94 formed in the manner of the flattened areas 47 hereinbefore mentioned. The spacing and positioning of the flattened areas is such that the same align with the openings 86 and 88. The numeral 96 designates a lever which is secured to an outer end of the shaft 98 and which is used to rotate and secure the shaft 98 as hereinafter explained.

Further provided is the boot plate 98 which is identical to the plate 16, but, in addition, has the flange 100 extending from the side edge thereof which has mounted thereon the clip 1&2. The binding shown in FIGURE 9 is' operated by holding the boot in the slightly raised position as shown and with the openings 36 of the connector lugs 24 and 26 in alignment with the flattened areas 92 and 94 of the shaft 91 The toe of the boot is then moved forwardly and downwardly so that the flattened areas 92 and 94 enter the openings 30 of the connector lugs 24 and 26 and the lugs rest upon the shaft 90. The lever 96 is then moved rearwardly and engaged by the clip 102 adjacent the sole of the ski boot. Such movement of the lever moves the openings 3t of the connector lugs out of alignment with the flattened areas 92 and 94 whereby the lugs are connected to the ski plate member 72 for limited pivotal connection therewith. To remove the boot, the lever 96 is lifted from engagement with the clip 102 to an angle whereby the openings 30 are in alignment with the flattened areas 92 and 94. As a result the lugs 24 and 26 may be removed from the shaft 90.

With the boot in connected position with the ski plate 72 it will be seen that the portion 76 thereof prevents snow from lodging under the extreme front portion of the boot where the same is quite undesirable particularly when the boot is attached having once been used in the ski. An accumulation of snow and ice on the ski at the point of the toe of the boot prevents easy connection of the boot plate with the ski plate 72.

In FIGURES 14 I have illustrated a further embodiment of the invention wherein is shown a portion of a ski E on which is mounted the ski plate 104.j The ski plate 104 includes the flat base portion'106 and extending upwardly therefrom at the opposed longitudinal edges are the upstanding spaced flanges 108 and 110. The flanges 108 and 110 are formed with the slots 112 and 114, respectively, which are angularly disposed to the ski E. The lower edge of each of the slots 112 and 114 is formed with the rounded entrance shoulder portion 116. Extending upwardly from the forward edge of the base 106 is the inclined front wall portion 111 having the spaced extended portions 113 and 115.

Rotatably connected to the flanges 108 and 110 is the shaft 118. In addition, I provide the throw-catch member 120 which includes the flat body portion 122 and angularly chsposed from the body portion 122 is the rear portion 124 which terminates in the lateral hook portion 126. At the angular junction of the body portion 122 and the rear portion 124 are formed the two spaced and depressed portions 128 and 130 stamped from the throwcatch member to form a bearing in the catch member 120 which receives the shaft 118 thereby pivotally mounting the throw-catch member 1 20 on the ski plate 104.

I further provide the boot plate 132 formed of the main body portion 134 which is secured to the sole of a ski boot. The boot plate 132 has formed on the forward 4 end of the main body portion 134 the broadened head portion 136 including the two spaced ear members 138 and 140 which mount the transverse rod 142.

The forward portion of the throw-catch member 120 is formed with the circular formation 144 which engages the arcuate spring catch member 146 mounted on the top of the ski to releasably thereby hold the throw-catch member 120 in the forward and downward position as shown in FIGURES 10-13.

In using the ski binding of FIGURES 10-14 the boot plate 132 is secured to the bottom of the boot. The user manipulates the boot and places the ends of the rod 142 into the slots 112 and 114 of the flanges 108 and with the clamp member 120 in the opened condition as shown in FIGURE 14. The clamp member is then pivotally lowered into the position of FIGURES 10-13 with the circular ring portion 144 in engagement with the catch 146. As the throw-catch member 120 is lowered from the position of FIGURE 14 to that of FIGURES 10-13 the hook 126 thereof engages the rod 142 of the boot plate 132 shown in detail in FIGURE 12. The hook 126 is so positioned that the outer end 127 thereof is closely adjacent a line extending between the upper edges of the slots 112 and 114 whereby the rod 142 cannot'be removed from the slots 112 and 114 and is neatly retained therein. 7

To release the boot from the plate 104, the throwcatch member 120 is lifted from the position of FIGURE 12 to that of FIGURE 14 thereby allowing removal of the rod 142 from the slots 112 and 114 of the flanges 188 and 110, respectively.

It will be seen that the inclined front wall portion 111, the spaced extended portions 113 and together with the throw-catch member substantially prohibit snow from entering under the front of the toe of the boot and that the disconnecting of the boot from the ski plate 104 is easily and simply made by taking a ski pole and raising the throw-cacth 120 by means of the ring 144. With such construction the skier does not have to bend over to connect or disconnect the boot from the ski plate 104. A heel plate such as 52 may be also used in conjunction with the clamp 62.

The invention is not to be understood as restricted to the details set forth since these may be modified within the scope of the appended claims without departing from the spirit'and scope of the invention.
