Definitions

  • the invention relates to a device for clamping an object under a predetermined clamping pressure, which automatically releases the object when the clamping pressure is exceeded by a predetermined value.
  • a predetermined clamping pressure for holding the object in the clamping device is not significantly exceeded so as not to damage or destroy the clamped object.
  • the predetermined clamping pressure in the described clamping devices should be easy to set and vary, the predetermined clamping pressure being dependent both on the clamped object, the material from which it is made, and the measures to which the clamped object is subjected.
  • such a device is intended with regard to clamping pressure be easily readjustable if the dimensioning of the clamped object changes in the clamping direction for any reason, for example due to shrinkage of plastic material when the temperature drops.
  • the adjustment of the clamping pressure should be possible quickly and easily; at the same time, if the clamping pressure is exceeded beyond a defined value, the clamping pressure is released and thus the clamped object is released immediately and reliably.
  • the object to be clamped is clamped between two clamping bearings which hold the object between them in punctiform or planar fashion.
  • a bearing which can for example be designed to be resilient in itself, has a device for adjusting the inspann réellees E, with which the object is clamped.
  • This device for pressure adjustment preferably serves at the same time as an indication of the clamping pressure actually acting on the clamped object.
  • the trigger pressure at which the clamping pressure is to be released is measured in the spring-loaded clamping bearing by pressure sensors or light barriers or the like which are known per se; these generate when the set limit of the clamping is reached pressure electronically a signal by which the lifting of the clamping pressure is triggered so that the clamped object is released.
  • a clamping bearing is designed such that it can be moved mechanically, for example by means of an adjusting screw, in the direction of the movable, spring-shaped clamping bearing. This ensures that when the length of the clamped object is shortened in the clamping direction, the specified clamping pressure is set to the opposite bearing by corresponding movement of this clamping bearing.
  • the mechanism for releasing the clamping pressure is triggered in the manner described when the predetermined and set limit value of the clamping pressure is reached.
  • FIGS. 1 to 11 a ski binding is described as a preferred embodiment of the device according to the invention.
  • the object 1 to be clamped is a ski boot;
  • the front, adjustable holding device for the tip of the ski shoe consists of a block 9 which is fixedly arranged on the ski 6 and in which an adjusting screw 2 is arranged for the adjustment.
  • the adjusting screw 2 acts on a slider 3 depending on the direction of rotation of the adjusting screw 2 in the direction of the automatic heel unit or is moved in the opposite direction.
  • the tip of the ski shoe is held by the component 5, which is arranged on the slide 3 in a height-adjustable manner by means of the screw 4.
  • centering rollers are provided on the side, Bolts and / or known clamp-like components are provided.
  • the construction described makes it possible to move the ski boot in the direction of the longitudinal axis of the ski as required by adjusting the set screw 2 and correspondingly displacing the slide 3.
  • Fig. 2 the embodiment of the invention is shown schematically as a ski binding.
  • the housing 13 of the automatic heel unit is arranged on the ski 6 in the rear region of the ski, in which a spring piston 18 is arranged in a spring piston housing.
  • the pressure exerted on the spring piston 18 by adjusting the adjusting screw 2 via the ski boot 1 is indicated by the position of the lever 15: this lever is arranged on an axis 16 which forms an angle of approximately 90 ° with the spring piston 18 , and is driven by this directly over matched profiles; this results in a pivoting of the lever 15 depending on the load on the spring piston 18, with markings, for example on the axis 16 and on the housing 13 in the region of the axis 16, from which the pressure can be read which acts on the spring piston 18.
  • this clamping pressure can be read on the label is in the range 16: Now the length of expansion reduces the ski boot 1 by cooling to, for example -10 0 C, by adjusting the set screw 2 of the ski boot 1 is pushed so far in the direction of the automatic heel unit 13 until the same marking setting is reached again, so that the predetermined clamping pressure is set.
  • FIG. 3 shows an automatic heel unit according to FIG. 2 in a side view; in this case, in a manner known per se, an operating lever 22 is added, which is connected to the spring piston 18 in the upper region of the housing 13 via a correspondingly adapted profile; Before the ski boot is clamped in, the system is in a relaxed position, i.e. the spring piston in position 18a, the pointer lever in position 15a and the operating lever in position 22a; in the tensioned state, the spring piston takes position 18, the pointer lever takes position 15 and the operating lever takes position 22. Otherwise, the reference numbers correspond to those according to FIG. 2.
  • the automatic heel unit according to the invention is shown schematically in section parallel to the ski surface.
  • the spring piston 18 is designed telescopically, the two parts of the telescopic spring piston 18 being supported against one another inside by a spring 36.
  • At least one pin 34a serves as a safeguard against rotation of the spring piston 18.
  • the spring piston 18 has a step-shaped stop 35, which prevents the spring piston 18 from coming out of the housing 13 beyond a certain amount.
  • stop pins, rollers or balls 38 are arranged in the housing 13, which block the escape of the rear part of the telescopic spring bolt 18. wherein the axis of these locking rollers 38 is guided in lateral vertical slot slots in the rear spring piston area.
  • a bolt 39 Arranged in the end region of the housing 13 is a bolt 39 which can be displaced in the direction of the longitudinal axis of the ski and which has a cylindrical recess in which the cylindrical rear region of the spring piston 18 can be received; when the bolt 39 moves towards the ski tip, the locking by the balls or rollers 38 is released by external ramps on the locking bolt 39, so that the rear region of the telescopic spring bolt 18 can enter the recess in the bolt 39, as a result of which the pressure of the spring piston 18 is practically lifted onto the ski boot heel.
  • sensors 42 for electronic pressure absorption are arranged in the housing 13 in particular in the outlet opening of the spring piston 18 from the housing.
  • Piezo elements are preferably used here which generate a certain voltage at a certain pressure, which unlocks the unlocking of the locking elements 38 by electromagnetic movement of the latch 39 in the direction of the ski tip at a certain limit value which corresponds to the previously set trigger pressure.
  • the pressure sensors light barriers or the like can also be used, which register the displacement of the spring piston 18 into the housing 13 with increasing pressure on the spring piston 18 in a manner known per se and the unlocking when a certain piston path that is proportional to the pressure increase is exceeded of the piston 18 within the housing 13 and thus cause the spring element 36 to relax.
  • the unlocking mechanism consists of the bolt or slide 39, which is connected to an armature 40, which in turn passes through a coil 41.
  • armature 40 When the unlocking signal is generated by the pressure sensors or light barriers 42 at a predetermined trigger pressure on the spring piston 18, a magnetic field is generated in the magnet coil 41, through which the armature 40 sets the slide 39 in the direction of the ski tip and thus the piston 18 ent locks and the spring 36 is relaxed.
  • the electromagnetic-electronic part of the device is powered by commercially available electric batteries 43.
  • the control works in such a way that the signals from the pressure sensors or light barriers 42 enter the respective values into a converter.
  • the converter can be pre-programmed to certain values by microswitches 44 in stages. If necessary, the converter can also be preprogrammed using a continuously adjustable resistor.
  • FIG. 6 shows the automatic heel unit according to the invention in accordance with FIG. 5 in a different functional state. While the rear element of the telescopic spring piston 18 is shown in the locked position in FIG. 5, this area has entered the recess provided in the slide or bolt 39 in FIG. 6; previously, the locking by the rollers 38 was effected by movement of the bolt or slide 39 unlocked in the direction of the ski tip, the rollers being pressed back into their bearings by the run-up profiles on the slide 39 in the region of the rollers. The described forward movement of the slide 39 was triggered and effected, for example, by a pressure exerted sideways on the tip of the spring piston 18 beyond the set limit value in the manner described.
  • the pressure sensors are preferably semiconductors, measuring strips or piezo elements, arranged on the piston or on the adjacent housing 13 and generate a certain voltage when the spring piston 18 acts on pressure.
  • this voltage is split across the voltage distributors R1 and R2.
  • the voltage required for the trigger value is preferably sampled at R2.
  • the same acts on a threshold switch V1, which transmits a pulse to a switching amplifier V2 when a certain input voltage is reached.
  • This excites one Coil L1 (coil 41 according to FIGS. 5 and 6), which builds up a magnetic field through which the armature 40 is moved with the slide 39 (according to FIGS. 5 and 6), whereby the spring piston 18 is unlocked.
  • Resistor R2 can be changed using a potentiometer or a microswitch, which optionally connects several resistors in parallel. This allows the voltage to be set at a given pressure.
  • the threshold switch is a circuit that is known per se as a signal converter.
  • the slide 39 (FIGS. 5 and 6) is reset outside the electronic control by a return spring, which is designated 45 in FIG. 5, for example.
  • a limit switch 22b (FIG. 3) is provided, which is automatically switched to position 22a (FIG. 3) by the opening lever in the idle state of the tensioning device. If a pressure of approximately 50% of the trigger pressure acts in the direction of the longitudinal axis of the spring on the spring piston 18, the opening lever 22 is raised to such an extent that the spring-mounted switch 22b is released and the circuit is closed.
  • the pointer or lever 15 according to FIGS. 2 and 3, which, in cooperation with corresponding markings on the housing 13, serve as an indication of the pressure acting on the spring piston 18, can preferably be designed as a ski brake.
  • the axis about which the member 15 rotates not parallel to the ski surface but at an angle of about 40 to 50 0, preferably 45 °; this ensures that in the tensioned state of the spring 36 the pointer 15 designed as a brake arm pivots over the width of the ski and thus does not protrude sideways beyond the ski.
  • a second pointer 15 designed as a brake arm can be arranged on the opposite side of the housing 13.
  • FIG. 8 another unlocking mechanism of the automatic heel unit is shown schematically, which otherwise the automatic heel unit according to FIGS. 5 and 6 corresponds.
  • the rear part of the telescopic spring piston 18 is locked by means of ball-like or roller-like locking elements 38, which are arranged opposite one another within this area.
  • the locking elements 38 suspended in the piston 18 are pressed in a locking manner partly through corresponding openings in the wall of the spring piston 18 into corresponding counter bearings or depressions in the adjacent housing wall, so that the lower region of the spring piston 18 is locked with the housing 13.
  • the locking elements 38 are held in the locking position by the bolt or slide 39, which enters the spring piston 18 through the rear wall thereof and between the locking elements 38.
  • the bolt or slide 39 is formed in one piece with the armature 40, which is arranged in the coil 41 and is set in motion in the manner described.
  • the bar 39 which is rod-shaped in the present case, tapers in its front end, the corresponding side walls forming a profile 63, on which the locking elements 38 roll up or roll off when locking or unlocking.
  • a spring element (not shown) is preferably arranged which, after unlocking and with complete relief of the front part of the spring piston 18, returns its rear region to the starting position for the locking.
  • the bolt 39 or the armature 40 is preferably extended through the rear wall of the housing 13, so that on the one hand the locking can be carried out by hand and on the other hand it can be checked visually whether the spring piston 18 is locked or not.
  • the housing 13 there is an assembly opening for the components of the automatic heel unit arranged inside, which can be closed by a screw closure 65. This ensures easy access to the interior of the automatic heel unit while at the same time excluding dirt and water. This also makes manipulation by third parties in the binding setting difficult.
  • FIG. 9 schematically shows a cross section through the area of an automatic heel unit according to the invention, in which the front part of the spring piston 18 emerges from the housing 13.
  • the pressure is taken up by only one electrical semiconductor 84, to which the pressure which is exerted on the tip of the spring piston 18 by the ski boot 1 by twisting or the like of the ski boot 1 in the binding, via one over the front region of the spring piston about 180 comprehensive backdrop 83.
  • An adjustable screw 85 serves as a counter bearing for the pressure transducer 84.
  • Two scenes are preferably arranged in a V-shape in the outlet opening of the spring piston from the housing, which surround the spring piston over a range of approximately 90 each, and which each bear on a sheet-like pressure sensor.
  • circular or semicircular sensors can also be used in analog application.
  • FIG. 10 shows a cross section in the left half of the figure and a longitudinal section in the right half through a locking mechanism according to the invention.
  • the two locking rollers 38 and the intermediate guide roller 70 with a smaller diameter are rotatably mounted on a common axis 75.
  • the axis 75 is arranged parallel to the ski surface and at right angles to the longitudinal axis of the ski in the rear area of the piston 18; the two ends of the axle 75 are supported in slots in the side walls of the rear area of the piston 18; the slots extend in the direction perpendicular to the ski surface, so that the axis 75, the locking rollers 38 and the guide roller 70 are movably mounted in this direction.
