- FIG. 8 ALB 7B Feb. 18, 1969 H. SCHEIB ETAL HEEL HOLDERS FOR SAFETY SKI BINDINGS Sheet 4 of Filed Aug. 31, 1966 FIG. 8
- a heel holder for safety ski bindings consisting of a pressure member to engage the heel groove of a ski boot.
- the pressure member is pivotally mounted to the ski on an axis located behind the ski boot.
- a spring resiliently urges the pressure member against the ski boot, with the pressure member being pivoted to a release position when experiencing an excessive force.
- the spring element is in the form of a gas spring which has the advantages of functioning as a spring when subjected to minor shocks, and, when subjected to an excessive shock, such as would require release, the gas spring serves to produce equalization of pressure about its piston and functions as a plunger damped by gas pressure so that it moves to a release position without a restoring force.
- heel holders for safety ski bindings in which a pressure member for engaging the heel groove is pivoted to the ski on an axis which is disposed behind the heel and said pivoted member is resiliently urged against the heel of the boot by a spring element, and pivotally movable to a release position against the action of the spring element by an excessive force, which is upwardly directed at right angles to the surface of the ski.
- the foot is generally placed into the binding in a simple manner by engaging the top of the boot with the pivoted toe iron and kicking with the heel on a closing pedal or the like, which is provided on the heel holder and is upwardly inclined in release position. In this manner the pivoted member is caused to engage the heel groove under the action of the spring force.
- the disadvantages of the known heel holders are avoided in a heel holder of the kind described initially hereinbefore in that the spring element consists of a gas spring, which comprises a cylinder filled with a gaseous fluid under superatmospheric pressure, and a piston which is slidable in said cylinder and provided at one end with a piston rod, which extends outwardly through one end wall of the cylinder in sealed relation therewith, said piston having one or more passage bores for the gaseous fluid, which bores have a total crosssectional area that is very small relative to the piston area.
- the piston area is preferably at least one hundred times the total cross-sectional area of the passage bore or bores.
- the gas spring is pivoted at one end to the pivoted member and at the other end to a member which is rigidly secured to the ski, the gas spring forms a toggle joint with the pivoted member, and the pivot which connects the pivoted member and the gas spring is adjustable relative to the pivoted member for varying the angle which is included by the lines which connect the pivots.
- the use of a gas spring has the special advantage that the force tending to extend the piston is almost constant in any position of the piston so that an increase of the spring displacement to be effected until the release takes place corresponds to a substantially proportional increase of the Work which is required for the release.
- the pivoted member may have a pivot pin, which mounts a bearing bracket for the gas spring, which bearing bracket is provided with a female screw thread and adjustable by a rotation of the pivot pin whereas the axis of the gas spring in operative position is approximately at right angles to the axis of the screw-threaded. pin.
- a heel holder of the kind described first hereinbefore comprises two double-armed levers or pairs of such levers, which are pivoted to a housing which is connected to the ski, one lever arm of each lever or pair is pivoted to the pivoted member and the other lever arm is pivoted to one end of the spring element, in such a manner that a movement of the pivoted member from its operative position toward the release position causes the pivots of the spring elements to approach each other until they have assumed a dead center position, and to move apart from each other after having passed through said dead center position.
- the pivoted member may comprise two pins, which extend in the longitudinal direction of the ski and extend through slots formed in the housing for guiding the pivoted member along the path which is desired for the release movement.
- the pivoted member may suitably be guided by means of its guide pins in cam slots formed in the double-armed levers.
- One of the double-armed levers may be provided at one lever arm with a closing pedal and at the other lever arm with an opening means.
- the just described embodiment can be used to special advantage together with a gas spring and is distinguished in that the gas spring or other spring element is subjected to two stresses during the release movement as the two pivots respectively connected to one of the two parts of the gas spring or to one of the two ends of other spring elements approach each other during the release movement, whereas in the known heel holders one of these pivots remained always stationary relative to the ski.
- the twofold utilization of the spring element permits the same effective resistance to the release to be produced with a smaller, less expensive spring element.
- a further embodiment of the invention may also be used in a heel holder of the kind described first hereinbefore independently of the use of a gas spring but is preferably used together with a gas spring as a spring element.
- the pivoted member is firmly connected to a closing pedal and this pivoted member and one end of the spring element are pivoted to one arm of a double-armed lever, the fulcrum pin of which slides during the opening and closing movements along the edges of aligned apertures in the housing, the guide edges effective during the opening movement are upwardly and rearwardly inclined, the guide edges etfective during the closing movement are approximately parallel, and the fulcrum pin is freely moveable in the aperture.
- This embodiment has the special advantage that, owing to the different means for guiding the fulcrum pin of the lever during the opening and closing movements, respectively, the force required for opening the heel holder is larger than that required for closing the same. Owing to this arrangement, the pivoted member cannot suddenly impinge with a large force into the heel groove when the heel holder is being closed. Such an impact is not only inconvenient for the user but may also cause premature wear of the boot and of the heel holder.
- a last advantageous embodiment of the invention may also be used with other spring elements, if desired.
- the pivoted member is mounted on a stud, which is pivoted to the ski for movement to the rear, said stud is approximately vertical in operative position, and the free end of the pivoted member, which free end engages the heel groove, is pivoted to a bail member, which is guided in a slot formed in the lever which is pivoted to the housing and carries the closing pedal, said slot being approximately vertical in operative position and the spring element bearing at one end on the housing and opposing the pivotal movement of the stud.
- This embodiment employs a tangential deflection and has the special advantage that it is not necessary to provide a sole holder which can be adjusted to heels of different height, as the end of the pivoted member may suitably be provided with a freely rotatable roller and is engageable with any heel groove.
- An opening lever is suitably pivoted to the housing and serves for retracting the spring element to enable a convenient stepping out of the binding.
- that end of the spring element which does not bear on the housing is guided in the housing and cooperates by means of a roller with a cam formed on the bail member.
- the cam may be shaped to provide for any desired behavior of the spring during the opening movement.

- FIG. 14 is a modification of the embodiment of FIGS. 10 to 13 and FIG. 15 is a top plan view showing the modification of FIG. 14.
- the pivoted member 3 and the closing lever 4 are pivoted to the housing 1 by the pin 2.
- the gas spring 11 is pivoted on the pin 51.
- the adjusting screw 5 is rotatably riveted in the pivoted member 3 and enables an adjustment of the sole holder 6 to any height of the heel.
- the screw 7 for adjusting the hardness of the spring and consequently the resistance to a release is also rotatably riveted in the pivoted member 3 and carries a bearing bracket 8, to which the piston rod 10 of the gas spring is pivoted by the pin 9.
- the force of the gas spring produces a torque about the pivot pin 2.
- the magnitude of said torque depends on the position of the bearing bracket 8 and on the force of the gas spring 11. An upward movement of the bearing bracket 8 by a rotation of the screw 7 will increase the torque because the force of the gas spring acts then on a larger level arm. The force required for a release of the binding can be adjusted in this simple manner.
- the torque causes a downwardly inclined force to be applied to the sole holder 6, which engages the heel groove over the end portion 12 of the heel of the skiing boot.
- This force can be resolved into vertical and horizontal components.
- the horizontal component urges the boot forwardly and ensures a firm engagement of the skiing boot with the toe iron.
- the vertical component urges the heel downwardly so that it is forced under the required pressure against the ski.
- the tensile force acting upwardly on the skiing boot in a vertical direction will exceed the downwardly directed component of the pressure applied by the sole holder so that the pivoted member 3 is moved about the pivot pin 2.
- the pivot pin 9 progressively approaches the dead center line, which extends through the pins 2 and 51.
- FIG. 3 is a sectional view taken on line AA in FIG. 2 and shows the heel holder after the release.
- the heel holder will also be in this position when the skier desires to step into the binding.
- the closing lever 4 By means of the closing lever 4, the heel of the boot forces the pivoted member 3 in the opposite direction beyond the dead center position so that the gas spring is again caused to produce the torque which resiliently urges the skiing boot against the toe iron and downwardly against the ski.
- the pivoted member 3 has a depression 13, which is engageable by the point of the ski stick to urge the pivoted member beyond the dead center position.
- the special feature of the step-in binding of FIGS. 4 to 6 resides in that the force of the gas spring is utilized in two ways.
- one spring end of the spring element was mounted on and supported by the housing of the binding, so that this end was virtually secured to the ski, whereas the other spring end acted on the detent means of the heel holder or was indirectly supported by the heel groove.
- the gas spring 11 is pivoted to two rocker levers 14 and 15, which are rotatably mounted in the housing 1 by the pivot pins 16 and 17.
- the pivoted member 3 is connected to the rocker levers 14 and by the pivot pins 18 and 19.
- the pivot pins 18 and 19 guide the pivoted member 3 in the slots 20 and 21. These slots are formed in the housing and have such a configuration that they constrain the pivoted member 3 to perform a movement which causes a release of the sole 12 during the release action.
- the adjusting screw 5 is rotatably mounted in the pivoted member 3 and enables an adjustment of the sole holder 6 to any height of the heel.
- the pins 18 and 19 are displaced along the guiding slots 20 and 21 and cause a pivotal movement of the rocker levers 14 and 15.
- the pins 18 and 19 are suitably provided with rollers which engage the slots 20.
- the rocker levers 14 and 15 are also formed with slots 22 and 23 to enable the pins 18 and 19 and the pivoted member 3 to follow the slots 20 and 21.
- a continued rotation of the two rocker levers 14 and 15 causes a progressive approach of the gas spring 11 to the dead center line, which extends through the pins 16 and 17, so that the gas spring is progressively compressed.
- the gas spring 11 is pivoted by pins 24 and 25 to the rocker levers.
- the rocker lever 15 terminates at its forward end in a closing lever 4 and at its rear end in an opening lever 26, which is formed with the depression 13 for engagement with the point of the ski stick when it is desired to open the binding.
- a depression of the closing pedal lever 4 by the heel will close the binding.
- the closed binding can be opened with the aid of the opening lever 26.
- the pivoted member 3 carries the rotatably riveted adjusting screw 5 and the sole holder 6 and forms a unit with the closing pedal 4.
- the pivoted member 3 is also formed with guide slots 27 on both sides. These guide slots guide the upper portion of the pivoted member 3 during the release movement.
- the lower portion of the pivoted member 3 is connected by the pivot pin 30 to the rocker lever 31.
- the pivot pin 30 is movable in a guide slot 32 formed in the housing 1.
- the rocker lever 31 is separately shown for the sake of clarity and provided with pins 33 and 34.
- the pin 33 engages the trapezoidal extension of the slot 32.
- the piston rod 35 of the gas spring 11 is pivoted to the pin 34.
- the gas spring 11 is mounted by the pin 36 in the housing 1.
- the pin 30 When a force is applied by the heel through the sole holder to the pivoted member, the pin 30 will be raised and take the rocker lever 31 along.
- the pin 33 and the housing slot 32 in the housing 1 cooperate to constrain the rocker lever 31 to rotate about the pin 30. This pivotal and lifting movement is opposed by the force of the gas spring.
- the pin 34 progressively approaches the dead center line, which extends through pins 30 and 36.
- the rocker lever 31 can swing down about the pin 30 until the pin 33 engages the horizontal, straight edge 37 of the guide slot 32.
- the force of the gas spring then rotates the rocker lever 31 about the pin 33 and causes the pin 30 and the pivoted member 3 to be raised further.
- cams 27 of the pivoted member 3 cooperate with the rollers 28 and constrain the pivoted member 3 to perform a movement whereby the sole holder 6 is progressively moved away from the end portion 12 of the heel and finally releases the heel.
- This embodiment has the special advantage that the pin 33 is on a lower level during the closing of the binding than during the opening movement, so that a much smaller force is required for closing the binding than for opening the same.
- the sudden shock which is experienced when the dead center line is overcome is relatively small because the force is also small at this time. Nevertheless, the full force is available during the subsequent release action.
- the binding is opened by hand by moving the opening lever 26 in the direction opposite to its closing movement, also under a low spring stress.
- the opening lever 26 is mounted on the pin 33 and embraces the pin 30.
- the step-in heel holders shown in FIGS. 10-15 involve tangential deflection.
- a roller 38 is rotatably mounted by a pin 39 in the pivoted member 3.
- the latter is pivoted on the pin 40 in the bearing bracket 41.
- the piston rod 35 of the gas spring 11 is pivoted by the pin 40 to the bearing block 41.
- the other end of the gas spring 11 is mounted on a pin 36 in the housing 1.
- the bail 42 is pivoted to the pin 39 and at its lower end has a pin 43, which engages the guide slot 44 formed in the closing lever 4, which is mounted on the pin 36.
- the bearing bracket 41 is mounted on a stud 45, which is pivoted in the housing 1 and extends approximately vertically in operative position.
- the pin 40 must leave its initial position and performs a rearward pivotal movement against the action of the gas spring 11. This movement is guided by the stud 45.
- FIG. 12 shows the binding in the position which it assumes at the time of the tangential deflection.
- the roller 38 was raised by the heel end portion 12 along its curved path.
- the pin 40 has been moved to the rear with the stud 45 and has forced the piston rod 35 into the gas spring 11 to a larger extent.
- the pivoted member 3 is moved to its uppermost position, in which the heel end portion 12 is entirely released.
- the closing lever 4 is pulled upwardly too and moved to its step-in position.
- pressure is applied by the heel to. the closing lever 4 and is transmitted by the pins 43, the bail 42, and the pin 39 on to the pivoted member 3 so that the roller 38 engages the heel groove.
- the binding is opened by hand with the aid of the opening lever 26, which is mounted by the pin 46 in the housing 1.
- the actuation of the lever 26 forces the piston rod 35 into. the gas spring 11 and at the same time pulls the pin 40 rearwardly.
- FIGS. 14 and 15 A modification of the step-in binding just described is shown in FIGS. 14 and 15.
- a roller 47 is mounted on a pin 48, which is carried by the piston rod 35 of the gas spring 11 and guided in the guide slot 4 9 formed in the housing 1.
- the b-ail 42. has a cam 50, which cooperates with the roller 47. For a release of the binding, the tangential deflection must be overcome and the gas spring is additionally compressed further by the cam 50.
- a further advantage of this design resides in that the need for a sole holder which is adjustable to the height of the heel is eliminated because the roller 38 will fall into any heel groove as it follows the pivotal movement R of the stud 45.
- a heel holder for safety ski bindings comprising a pressure member for engaging a heel groove of a ski boot, means pivotally mounting said pressure member to the ski on an axis which is disposed behind the heel, a spring element resiliently urging said pressure member against the heel of the boot, said pressure member being pivotally movable to a release position against the action of the spring element by an excessive force, which is upwardly directed at right angles to the surface of the ski, the spring element being in the form of a gas spring which comprises a cylinder filled with a gaseous fluid under superatmospheric pressure, and a piston which is slidable in said cylinder and provided at one end with a piston rod, which extends outwardly through one end wall of the cylinder in sealed relation therewith, said piston having at least one passage bore for the gaseous fluid, which bore has 'a total cross-sectional area that is very small relative to the piston area.
