  • This safety binding is attached to the ski together with a cooperating toe fixture.
  • a preferred safety ski heel binding removably fastens the boot heel by means of two separate stresses in the horizontal and vertical directions with respect to the ski.
  • Various types of prior art devices have been proposed to control adjustment of these separate stresses and consequently of the degree of safety.
  • a safety skiheel binding comprises a base attached to the ski, side frames slidably guided in engagement with the base (in the lengthwise direction relative to the ski) through the medium of a spring arranged along the base, and a casing turnably fixed to the rear upper end portion of the 3,497,230 Patented Feb. 24, 1970 side frames.
  • Two heel engaging means are cooperatingly positioned and fixed to the fore end face of easing. One is adapted for engaging the heel from below and the other for engaging the heel from the top.
  • a swinging link is rockably pivoted at the upper portions thereof to the upper fore portions of the side frames, and at the lower fore portions thereof to a fore link turnably fixed at the other end thereof to the lower fore portions of the casing.
  • An unlocking lever is rockably fixed to the rear upper end portions of the side frames where the casing is also turnably fixed.
  • a connecting link is turnably connected at one end thereof to the fore end portions of the unlocking lever and at the other end thereof to the said lower fore portions of the swinging link.
  • Another spring is provided between a spring-receiving means connected to the lower rear portions of the swinging link and a pressure adjusting means screwed into an adjusting screw rotatably fixed to the rear back portion of the casing.
  • the swinging link may be rockably pivoted to the lower fore portions of the side frames, not to the said upper fore portions of the side frames.
  • the heel tightening operation of the present safety binding is automatically carried out by stepping on and pressing down the heel engaging means with the boot heel.
  • FIG. 1 illustrates the basic structure of a toggle joint adapted as the operating principle of this invention
  • FIG. 2 is the schematic diagram of the first embodiment of this invention.
  • FIG. 3 is a top plan view, partially cut-away, of the first embodiment according to this invention.
  • FIG. 4 is a side view, partially cut-away, of the first embodiment in the locking position

  • a and B are therefore fixed relative to a frame of reference.
  • F represents an intersection of AB and the extension of DC
  • S represents a stress of the spring 60 best illustrated in FIG. 2.
  • the extension of S intersects CD at G. It is essential in this invention that G intersects the straight line between C and D.
  • reference numeral 10 denotes a base attached to the ski.
  • the base 10 has extension part pieces 12 with fixing holes 11, guiding flanges 13 upwardly and then outwardly extending respectively on both sides thereof, and a vertical wall 14 at the rear end thereof, see FIG. 5.
  • the side frames 30 have grooves 31 at their lower end portions which slidably engage with the guiding flanges 13, respectively. For clarity, only one side frame 30* is shown in FIG. 6, and only one casing, however two of each, are used.
  • a spring is arranged along the axis of the ski.
  • the spring 20 is connected at one end to a spring receiving means 21 and at the other end thereof with a spring washer 25.
  • the adjusting screw 23 passing partly through the spring 20 is rotatably fixed to the vertical wall 14 and screwed into the spring-receiving means 21.
  • the adjusting screw 23 has a head 24 hearing on the rear face of the vertical wall 14.
  • the spring washer 25 is secured to the side frames with a pin 26 fitted within holes 32 of the side frames.
  • An elastic member 27, preferably of rubber, is fitted around the spring washer 25. The elastic member 27 is in contact with the upper face of the base to prevent looseness of the adjusting screw 23 caused by oscillation in skiing operations and consequently to maintain a desired pressure of the spring 20.
  • the spring-receiving means 21 is provided with projecting parts 22 passing through slots 35 in the side frames 30.
  • a casing fits over the side frames 30.
  • the casing 40 is turnably fixed to the side frames 30 by means of a pin 54 passing through holes 34 and 44.
  • a heel engaging means 41 is positioned adjustably for boots of different size and fixed with a fixing screw 42 to the fore end face of the casing 40, see FIGS. 4 and 5.
  • a heel bottom receiving means 43 is secured to the fore portions of the casing 40 with pins 56 and 57.
  • a swinging link 46 is rockably pivoted with a pin 53 in a hole 33 of the upper fore portions of the side frames 30.
  • a fore link 45 is turnably connected at one end thereof to the lower fore portions of the swinging link 46 with a pin and at the other end thereof to the lower fore portions of the casing 40, by means of the pin 57.
  • the swinging link 46 is provided with a spring-receiving means 65 connected to a bar thereof.
  • An adjusting screw 63 is rotatably fixed to the rear back portion of the casing 40 and has a head 64 bearing on the rear back portion of the casing 40.
  • a pressure adjusting means 61 is screwed into the adjusting screw 63 and an extension arm 62 thereof is in contact with the inner surface of the casing 40.
  • a spring 60 is arranged between the spring-receiving means 65 and the pressure adjusting screw 63.
  • the spring 60 is so arranged that the dynamic production (extension) thereof intersects the straight line, preferably the lower part thereof, between the centers of the pins 55 and 57 in the locking position.
  • the unlocking lever 48 is rockably pivoted with the pin 54.
  • the fore end portions of the unlocking lever 48 is turnably connected to a connecting link 47.
  • the connecting link is turnably connected to the pin 55.
  • the heel of the boot is fixed in the position by the pressure of the spring 60 as well as that of the spring 20.
  • the desired pressures are obtained by a very simple operation of turning the respective heads 24 and 64.
  • the extension arm 62 may be adapted by markings, for a pressure indicator 66 of the spring 66.
  • the locking position is automatically reached by stepping in the binding with the boot heel and pressing downwardly the heel bottom receiving means 43 against the pressure of the spring 60 and that of the spring 20.
  • the pressure of the spring 60' causes the casing 40 to turn counterclockwise about the pin 54 as soon as the pin 57 is lowered to the extent that the straight line between the pins 55 and 57 intersects the dynamic production (extension) of the spring 60.
  • unlocking lever 48 If one intends to open the binding by hand, one may press down the unlocking lever 48, for example, by putting the end portion of a ski pole into a hole 49 of the unlocking lever.
  • the pin 55 and consequently the swinging link 46 are pulled a little rearward through the connecting link 47 and the center of the pin 57 is carried upwardly above the dynamic production of the spring 60, the casing 40 will be thrown up clockwise to disengage the heel satisfactorily.
  • the second embodiment according to this invention has the swinging lever 46 rockably pivoted to the pin 26, not to the pin 53. Except in this respect, the second embodiment is just the same as the first embodiment.
  • an extension arm 62 is made of relatively thickmaterial differing from thin spring sheet of the prior art.
  • the fore end portion of the extension arm 62 is fitted with a pressure indicator 66 and the rear portion thereof is bent downwardly and a tapped hole 67 projecting inside is made on the rear portions thereof by rolling.
  • An oval hole 70, through which the adjusting screw 63 is inserted, is made at the rear back portions of the casing 40, as shown in FIG. 9.
  • the extension arm 62 is so arranged, as shown in FIG. '9, that it can be moved back and forth by turning the head 64 of the adjusting screw 63. As the hole 70 is made as an oval hole, an angle of the adjusting screw 63 to the casing 40 is somewhat changeable. Because of this, the extension arm 62 always keeps pressing the inner surface of the casing 40, including the unlocking position in which the spring 60 is curved by compression, as shown in FIG. 9.
  • the extension arm 62 is arranged so that the indicator 66, projecting from the window hole of the casing 40, is not rovided with the flanges of the prior art which are utilized to move the extension arm 62 along the window hole. The flanges prevent the extension arm from moving smoothly when the snow is within it and also they permit the snow to enter into the binding from the window.
  • the extension arm being made of relatively thick material, it is easy to fit the indicator 66 onto the extension arm 62.
  • a safety ski heel binding comprising, in combination,
  • a base adapted to be attached to the ski
  • a swinging link pivotally connected at the upper portion thereof with a second pin to the upper fore portions of the side frames and pivotally connected at the lower fore portions thereof with a third pin to a fore link, said fore link being turnably connected.
  • a first spring arranged between a spring-receiving means connected to the lower rear portions of the said swinging link and a pressure adjusting means rotatably fixed to the rear back portions of the said casing and so arranged that, in the locking position, a dynamic production of the spring intersects the straight line between the center of the said third pin and that of said fourth pin and a second spring positioned between said base and said side frames to act against a spring adjustable means to slide said frames along said base.
  • the second spring is arranged along the ski between a spring washer secured with a fifth pin to the lower fore portions of the said side frames and a springreceiving means having projecting parts passing through slots in the lower portions of the side frames and screwed into an adjusting screw rotatably fixed at the rear end portion of the said base.
  • safety ski heel binding as in claim 1 wherein said pressure adjusting means for the first spring has an extension arm having indicator means and a pressure adjusting screw.
