Definitions

  • ABSTRACT [30] Foreign Application Priority Data A method and a device for automatically releasing a Sept. 13. 1972 Germany 2244949 Ski hoot from 11 Ski which the boot is mouhtcdin the event of danger to the skier.
  • the forces acting in a [52] US. Cl. 280/ll.35 M skicris leg are continuously monitored and are 51] int. c1.
  • A63c 9/08 p r a predetermined inierviii of time. with ii 58] Field of Search 280/1135 M threshold valuewhen the forces reach 11 predetermined value, related to the threshold value.
  • the ski [56 ⁇ References Cited boot is released from the ski.
  • the resistance means are so selected that they put up a great resistance to jerky loads of short duration. that resistance then being reduced when the loads last longer. Jerky loads are considered to be loads lasting a maximum of about 0.3 seconds.
  • the shock energy is absorbed by special shock absorbing facilities. e.g. dampers or inertia masses.
  • dampers or inertia masses are used in these bindings to absorb shock energy.
  • This invention follows a completely new course and first proposes a method of automatically releasing a ski boot from a ski. in the event of danger which method consists in the fact that pulses acting on the skiers leg are continuously picked up and compared with a predetermined pulse quantity forming a threshold value. and in the fact that the connection between the ski and ski boot is released when that threshold value is reached.
  • this method affords the substantial advantage that the path is not employed as a measuring quantity for the releasing instruction.
  • an arithmetic mean value can be continuously formed from consecutive pulses realtive to a predetermined constant time section and compared with the threshold value.
  • a device for performing the new method in its simplest form is characterised according to the invention by at least one ski boot holder. a locking feature that fixes the ski boot holder. at threshold value switch influencing the locking feature. a time evaluation element and a pressure recorder.
  • the time evaluation element may be an integral element. It is appropriate to use a time evaluation element that takes the form of an inegrating amplifier having an adjustable time constant.
  • the locking feature can be designed with a release mechanism having an actuating element held normally in the unstable state of equilibrium.
  • the release mechanism element is coupled to a control organ of the threshold value switch.
  • the release mechanism comprises a toggle lever held normally in the extended position.
  • the ski boot holder takes the form of a sole plate held detachably on the ski.
  • a constructive configuration of this underlying idea of the invention is obtained in that the toggle lever is hinged directly with one arm and indirectly via a stop lever with the other arm to the sole plate or'a part firmly connected to said plate end in that there is a ski fitting (i.e. fitting attached to the ski). interacting with the stop lever.
  • the stop lever may have a nose and the ski fitting a notch.
  • the ski fitting takes the form of a spring-loaded swivel member.
  • stop lever is designed as a two-arm lever and when the toggle lever is hinged onto the lever arm facing away from the lock. It is also appropriate when there is a stabilising spring which engages on the stop lever and always endeavours to hold the toggle lever in its extended position.
  • a further configuration of the invention which is similarly independent of the above-described features may consist in the fact that the sole plate is held quasi-rigidly on the ski via a base plate that can be detached together with it from the ski.
  • the sole plate is supported by the base plate at four points. Both for constructive reasons and for reasons relating to the manufacturing and safety technicalities it has proved advantageous when the sole plate overlaps the base plate in the form of a box and is secured against lateral movements by spotlike contact points on the base plate.
  • the base plate can carry a pressure recorder acting on the sole plate for torsion loads and one for bending loads. a time evaluation element and a threshold value switch being assigned to each pressure recorder.
  • sole holders known per se may serve as ski boot holders. It is also just as possible to house at least some of the device parts-in the sole of a ski boot in a manner known per se.
  • an impedance transformer stage In a constructive configuration of the electronic system an impedance transformer stage. a carrierl'requency oscillator. a rectifier stage and an arithmetic mean value generator may be provided between the pressure recorder and the threshold value switch.
  • FIG. I shows a diagrammatic side view of the device:
  • FIG. 2 shows a similarly diagrammatic top view ofthe sole plate and base plate of the device according to FIG. I. the representation of the actual ski boot holders and locking feature being omitted;
  • FIG. 3 is a diagrammatic side view of the locking feature according to the invention in the normal operating state
  • FIG. 4 shows the feature according to FIG. 3 instantaneous state upon release
  • FIG. shows the feature according to FIGS. 3 and 4 in the instantaneous state when the sole plate engages again after a compulsory release
  • FIG. 6 shows a circuit diagram of the electronic pres sure recording system.
  • the safety binding illustrated diagrammatically in FIG. 1 has a sole plate 1 on which a ski boot 2 is held in any given suitable manner. being only arbitrarily detachable.
  • a front sole holder 3 which is notshown in further detail is held on the sole plate for adaptation to various boot sole lengths and thicknesses. both the height and length being adjustable.
  • a rear sole holder 4 can pivot around a horizontal transverse axis 5 and is connected firmly to an entering pedal 6.
  • the swivel bolt 7 is spring-loaded and can be swivelled to the right relative to FIG. 1, for example by means of a ski pole tip against spring force. so that sole holder 4 is released and ski boot 2 can be lifted off sole plate 1.
  • the rear sole holder 4 is followed by the electronic pressure recording sytem which is designated by nu meral 50 as a whole and described in detail with reference to FIG. 6.
  • sole plate 1 is held on the ski via a base plate 11 that can be detached together with it from ski 1.
  • the front end of the sole plate is equipped with a pocket 12 into which two swing arms 13 of base plate 11 engage.
  • the swing arms are so designed that they take up tensile and compressive forces perpendicularly to the ski plane in the with slight deformations whereas the deformations are relatively great for forces horizontal to the ski plane. Roughly in the range of the rear ski boot and there is a connection between sole plate 1 and base plate 11 via two buffers'l-i.
  • Sole plate 1 overlaps base plate 11 at least along the two long sides. Roughly in the range of the extension of the leg axis the turning centre between the two plates is formed in that base plate 11 has two lateral cams 15 (see FIG. 2) which are in spot-like contact with the longitudinal side walls of sole plate 1 which are drawn downwards. The transverse forces occurring during the travelling motion which do not cause the leg to twist can thus be picked up.
  • the base plate ll bears a pressure recorder 51' of the electronic pressure recording system.
  • the pressure recorder is a capacitive pickup.
  • the pick-up is in active contact with the rear end of sole plate 1, the contact being such that the torsion forces acting on the sole plate are recorded and measured by the pick-up. Interference quanities are practically eliminated in the torsion measurement by the above-mentioned dimensioning of swing arms 13 and buffers 14.
  • the forces which act on sole holder 4 in a roughly vertical upward direction and occur on frontal loading are transmitted by sole plate 1 to a further pressure recorder 51" which is likewise a capacitive pickup.
  • This pick-up is also connected firmly to base plate 11.
  • base plate 11 The front end of base plate 11 is held detachably on the ski surface by a ski fitting 16.
  • the base plate is held with its rear end on the ski surface by a locking feature which is designated by numeral 20 as a whole and can be unlocked automatically in the event of danger.
  • locking feature 20 comprises a toggle lever consisting of the two arms 21, 22 and knuckle joint 23.
  • Arm 21 of the toggle lever is directly hinged onto base plate 11 whereas arm 22 is hinged onto a stop lever 24 which is in turn mounted pivotably on base plate 11.
  • the .toggle lever is normally held in its extended positionand is thus in an unstable state of equilibrium.
  • FIGS. 3 and 5 show the locking feature in various instantaneous states on a larger scale than in FIG. I. Like FIG. 1, FIG. 3 shows the locking feature with the safety binding in the normal operating condition.
  • Stop lever 24 is designed as an elbow-lever, toggle lever arm 22' being provided on one of the lever arms and the free end of the other lever arm being angled and designed to form a detent nose 25.
  • This detent nose is in active contact with a notch in a swivel member 26 attached to the ski surface.
  • This swivel member is normally held in its locking position under the influence of a pressure spring 27.
  • a stabilising spring 28 which is desinged as a tension spring and hooked at one end onto base plate 11 also engages on that arm of stop lever 24 that is connected to the toggle lever. This stabilising spring is designed firstly to move the toggle lever back to its extended position after the release of base plate 11 from ski I0 and secondly to prevent the toggle lever from folding up unintentionally.
  • Knickle joint 23 forms the actuating element which can be operated by a control organ. for example by the core 30 of a plunger coil which receives an electric pulse as a control instruction from threshold value switch 57 to unlock the inter-arrested parts 25, 26 for the purpose of releasing base plate 11 and ski boot 2 connected to it via sole plate 1 from ski 10 in the event of danger.
  • detent nose 25 of stop lever 24 is held in non-positive contact in the notch in swivel member 26 both upwardly and toward both sides.
  • that arm of stop lever 24 that is connected to the toggle lever describes an upward swivelling motion independent of the load after the emission of an unlocking control instruction. which upward swivelling motion causes the toggle lever to fold up further.
  • the electronic pressure recording system consists of the following groups: pressure recorder 51, transmission line 52. impedance transformer stage 53, artithmetic mean value generator 56 and threshold value switch 57.
  • the electronic pressure recording system operates in the following manner.
  • the reaetance of capacitive pressure recorder 51 is proportional to the plate spacing of the pick-up, i.e. the voltage across capacitor C is proportional to the spacing of the pick-up plates and hence to the pressure when the current is impressed.
  • the current is im pressed in that a fixed voltage U determines the current across capacitor C,.
  • the output voltage 5 U is almost equal to the voltage across C with regard to frequency and amplitude.
  • Output voltage U is physically uncoupled and applied to the recitifer via capacitor C In a rectifier stage the AC voltage U is rectified with the aid of a half-wave rectifier.
  • An arithmetic means value is formed via an integrating amplifier having an adjustable time constant. This arithmetic mean value is the quantity which best describes the pressure and energy curve in the static and dynamic conditions. It is therefore employed for releasing purposes.
  • threshold value switch 57 Behind stage 56 which forms the arithmetic mean value there is a threshold value switch 57, the reference potential of which fluctuates to the same degree with the operating voltage as the DC voltage component of the measured quantity, i.e. operating voltage fluctuations are thus balanced out directly.
  • the output signal of threshold value switch 57 is directly employed for releasing purposes in the device described. However. it is also basically possible to order the output signal.
  • Impedance transformer 53 is formed by transistor Q at which an automatic working point adjustment is made by resistors R R and capacitor C In order to amplify the voltage at O as close as possible to l l. the punch-through of Q is reduced via transistor Q. the working point of Q being set by resistors R and R The output signal of Q, is fed' back to stage Q via C The modulation capacity of the impedance transformer stage is increased (amplitude i 6 V at U 9 V) bythe use of coil L, which is resonated with the carrier frequency with capacitor C v The carrier frequency is coupled into impedance transformer stage 53 via transformer Tr and capacitor 1-
  • Carrier frequency oscillator 54 is formed by the complementary COS-MOS transistor pairs 0;, Q,.
  • Capacitors C and C serve to physically decouple the oscillator circuit 0;, Q,. Q Q Resistor R ensures that the oscillator will build up correctly]
  • Resistors R and R serve to limit the current and reduce the current carried by the oscillator Resistors R. and R serve to screen out th e oscillator fundamental.
  • Rectifier stage 55 is formed by the operation amplifier V.. the current carried by it being governed by re sistor R Rectification occurs at diodes D, and D resistors R and R being the feedback resistors for amplifier V A zero shift-is made via resistor R.; so that the input current of the rectifier stage bccomeszero for a presssure of zero across measuring capacitor C A current corresponding to the pressure measured flows through resistor R to the rectifier stage.
  • FIG. 4 shows the locking feature in the instantaneous state upon safety release.
  • the threshold value switch gives the release pulse
  • base plate 11 which had been held quasi-rigidly on the ski surface beforehand is released spontaneously.
  • Control organ 30 moves the toggle lever with little' force from its extended position and the toggle lever can then fold up promptly practically of its own accord under the influence of the releasing force and detent nose 25 can get free of swivel member 26
  • stabilising spring 28 the toggle lever assumesits extended position again immediately afterwards: So that ski 10 cannot run away from the skier after this automatic release of ski boot 2 from s ki 10, a catching element is provided between base plate 11 and ski 10 in a manner that is known and therefore not represented.
  • the skier can step onto the ski again with the base plate which is attached to the ski boot.
  • the front end of the base plate is placed under fitting 16 (FIG. 1) and detcnt nose 25 of stop lever 24 interlocks with swivel member 26 at therear end of the base plate; to this end.
  • swivel member 26 can swivel to the right relative to FIG. 5 against the force of pressure spring 27 before the conditionaccording to FIG. 3 is attained again.
  • Locking feature 20 described with reference to FIGS. 1 to 5 can also be used in principle with toe clamps and heel holders in conjunction with the electronic pressure recording system where it replaces the former locking features of these binding parts.
