Definitions

  • the invention relates to a ski pole, which is adjustable in length, with two telescopically displaceable tube sections, which can be fixed in their mutual position by a locking device, with an operating element on the ski pole handle for fixing the two tube sections or for releasing the fixing, whereby the actuating member can be reached from the fingers of the hand holding the ski pole, the locking device being designed as a bolt with a plurality of bolt latches, and a spring supported on one end on the inner tube section and on the other end on the outer tube section, which tends to axially push both tube sections apart .
  • Such a ski pole can be used on the one hand as a rigid ski pole with an adjustable length and on the other hand as a resilient ski pole. This is particularly interesting for a cross-country pole, because on the one hand the stick length can be adapted to the terrain and on the other hand the spring force stored in the stick as Feed aid can be used.
  • Such a ski pole is known from NO-PS 73 712.
  • the latch consists of elastically radially expandable tongues which are actuated by the actuating member via an axial rod.
  • the latch catches consist of circumferential grooves.
  • the actuator is designed as a push button. If the button is not pressed, the two pipe sections are locked together and there is a rigid ski pole with the length set in each case. As long as the button is pressed, the lock is released and there is a resilient ski pole.
  • the disadvantage of this ski pole is that when the ski pole is used as a resilient cross-country pole to use the stored spring force as a feed aid, the operating button must always be kept depressed.
  • the latch is not set to predetermined, e.g. can inevitably snap in two or three bolt latches if the ski pole is in motion, i.e. when resting on the ground, has reached the desired length.
  • the stick can be adjusted from a resilient stick to a rigid stick and vice versa, and the rigid stick can be lengthened or shortened while running without impairing the running rhythm.
  • the aim is to create a ski pole with which the aforementioned disadvantages can be avoided.
  • the ski pole according to the invention is characterized in that the latch is present in the case of a two-armed rocker arm which is in the ski pole handle-bearing, outer tube section is mounted, that the rocker arm is spring-loaded, and that the bolt is attached to one rocker arm and the other Ki pp lever arm attacks the actuator.
  • the ski pole has an inner tube section 1, which carries the snow plate and the ski pole tip at the lower end, not shown. There is also an outer tube section 2, which is only extends a little over the length of the ski pole grip.
  • the ski pole grip comprises a shell 3 consisting of a plastic material, which is formed in several parts in practice, but is shown in one piece in the drawing for reasons of clarity. In the case of cross-country ski poles, this plastic shell 3 is at least partially preferably covered with suede, which is not shown.
  • the outer tube section 2 is provided with a fitting 4 which has an outer contour according to the line 5. This fitting 4 has a cut surface 6.
  • the fitting 4 has a U-shape, the two free leg ends in the drawing on the left and the two legs lying parallel to the drawing plane. These two legs are each provided with a bearing bore for receiving a journal 7.
  • the bearing shell 3 is provided with a slot-like opening 8, at the mouth edge of which a sealing ring (not shown) can be attached.
  • a clamping eccentric 11 which is mounted in a clamping bracket 12.
  • the screwing used for tensioning the clamping bracket 12 also serves at the same time for mounting the clamping eccentric 11.
  • the clamping eccentric 11 is used to clamp the two ends of the tape, not shown, which are provided for the hand in a loop, not shown.
  • This loop is available in a known manner with every ski pole handle.
  • the two mentioned bands of the loop ver run in a longitudinal channel 9, which lies between the shell 3 and the outer tube section 2. The loop then protrudes from the handle when there is an opening 10.
  • the locking device of the ski pole in the first exemplary embodiment according to FIGS. 1 and 2 is now explained below, with which the two mutually displaceable tube sections 1 and 2 can be fixed in their mutual position, in which case this fixing can be released again.
  • the inner tube section 1 carrying the ski pole tip and the snow plate is fastened to a tubular handle insert 1 'by means of a screw 13.
  • the handle insert 1 'and the outer tube section 2 are made of light metal and have a cross-sectional area (not shown) such that they form a groove and ridge anti-rotation device with respect to one another.
  • a bearing bush 14 made of a plastic or brass is axially displaceably guided in the outer pipe section such that the inner pipe section 1, 1 'is held in a non-rotatable manner with respect to the outer pipe section 2.
  • a bearing bush 15 made of brass or plastic is immovably inserted in the handle insert 1 '.
  • the aforementioned components 1, 1 ', 14 and 15 are therefore immovably connected to one another and carry the ski pole tip and the snow plate at the right end of the ski pole, not shown.
  • the inner tube section 1, 1 ' is provided with three locking latches 16, 17 and 18.
  • the two locking latches 16 and 17 are designed as an opening in the inner tube section 1, 1 ', and the locking latch 18 is designed as an end-side support shoulder in the bearing bush 15 and thus in the inner tube section 1, 1'. 2 clearly shows that this support shoulder 18 with respect to the longitudinal central axis of the components 1, 1 'and 15 is eccentric.
  • the bolt latches 16, 17 and 18 lie one behind the other in the longitudinal extent of the inner tube section 1, but on both sides of the aforementioned longitudinal central axis.
  • the bolt latch 17 can be a circular hole
  • the bolt latch 16 is designed as an elongated hole with the same width as the diameter of the bolt latch 17.
  • the fitting 4 carrying the journal 7 is fastened to the outer tube section 2 by means of a screw 19.
  • a sleeve 20 is still held in the outer tube section 2.
  • the sleeve 20 is provided with a bearing 21 for a two-armed rocker arm 22.
  • a latch 23 is attached to one rocker arm and an actuator 24 engages the other rocker arm.
  • the rocker arm 22 is mounted on the outer tube section 2 via the screw 19 and can assume the two tilted end positions shown in FIGS. 1 and 2 and an intermediate middle position, not shown in FIGS. 1 and 2, in which the rocker arm 22 is parallel to the longitudinal central axis of the outer tube section 2.
  • a rubber buffer 25 which can consist, for example, of foam rubber, so that air bubbles are enclosed in cells.
  • the support shoulder 18 connected to the inner tube section 1 can rest against this rubber buffer 25 (FIG. 1).
  • a helical compression spring 26 which is supported at one end on the bearing bush 15 and thus on the inner pipe section 1. With its other end, the spring 26 is supported on the sleeve 20 and thus on the outer tube section 2. This helical compression spring tends to axially press the two pipe sections 1 and 2 apart, the end position shown in FIG. 2 and thus the greatest ski pole length is reached. Even in this state, the spring 26 is still biased.
  • FIG. 1 shows the compressed position of the spring 26, the other end position, namely the shortest length of the ski pole, being reached.
  • a wire loop 27 which is articulated on the rocker arm 22 and is bent in a hairpin shape in the free end area 28, so that in the area 28 the wire loop 27 surrounds the screw 13 on both sides.
  • the spring 26 can therefore only relax until the end 29 of the loop 28 abuts the screw 13.
  • the ski pole length can be changed by 70 mm in one embodiment.
  • the latch 23 bears against the support shoulder 18 of the bearing bush 15.
  • the latch 23 lies in the latch latch 16.
  • the actuating member 24 for the rocker arm 22 is designed as a cam disk which can be rotated about the bearing pin 7 and whose axis of rotation, namely the longitudinal axis of the bearing pin 7, is at right angles to the ski pole axis.
  • the cam disk 24 is provided with four cams 30, 31 32 and 33. From Fig. 2 it can be seen that the cam 30 projects significantly beyond the immovable handle of the ski pole. With this rotated position of the cam disk 24, the cam 31 could in practice lie approximately flush with the grip shell 3. In the embodiment shown, the cam 31 protrudes only slightly beyond the grip 3 to the outside. 2 shows the one rotated end position of the actuating member 24, and in FIG.
  • the actuating member 24 is in this case placed in the upper region of the ski pole grip in such a way that it lies in the region of engagement of the index finger of a hand carrying the ski pole.
  • the two cams 30 and 31 are therefore intended to be pressed alternately into the interior of the ski pole grip by an operator.
  • the other two cams 32 and 33 are always within the ski pole handle.
  • the rocker arm 22 is under the action of a rocker arm spring 34, one end of which is supported by a pin 35 on the fitting 4.
  • the other spring end 36 rests on one arm of the two-armed rocker arm 2.
  • the spring 34 tends to push the rocker arm 22 into the end position shown in FIG. 1.
  • the actuating member 24 is connected in motion via the cams 32 and 33 to the rocker arm 22 and thus to the bolt 23 in order to bring the bolt 23 into or out of engagement with one of the bolt latches 16, 17 or 18. 1, the rocker arm spring 34 is still biased.
  • the actuating member 24 is pressed into the other end position shown in FIG. 3, so that the cam 30 lies inside the immovable handle 3, the rocker arm 22 is countered by the cam 33 Force of the rocker arm spring 34 is pressed into a position approximately parallel to the longitudinal axis of the ski pole, so that the latch 23 is out of engagement with the Bolt latch 16 arrives and is therefore not in contact with component 1 '.
  • the two pipe sections 1 and 2 are no longer locked together and the two pipe sections 1 and 2 can be telescopically displaced into one another in a spring-elastic manner.
  • the cam 31 of the actuating member 24 is pressed inwards, as shown in FIG. 2.
  • the bolt 23 then disengages from the bolt latch 17 and is held locked in the position shown in FIG. 2.
  • the stick is now the longest.
  • the extension of the stick is thus carried out by the force of the spring 26.
  • This spring can therefore be made relatively weak, and practice has shown that the force to compress the spring 26 into the position according to FIG. 1 is in the range of Should be 1 to 2 kp.
  • This lengthening of the ski pole can be carried out by the cross-country skier, for example, when the ski pole has been lifted off the ground and is moved forward, before the ski pole is supported on the ground again.
  • the following procedure is followed.
  • the actuating member 24 is pressed inwards at the bottom, ie the cam 30 is pressed into the inside of the handle according to FIG. 3, so that the rocker arm 22 is held in a position parallel to the longitudinal axis of the ski pole by the cam 33.
  • the ski pole is now supported on the ground via the pipe section 1 and the cross-country skier presses the pipe section 2 downward against the force of the spring 26.
  • the bolt 23 held in the center of the pipe section 2 passes through the bearing bush 15 into the interior of the component 1 '.
  • the actuator 24 is released so that it assumes its central position shown in FIG. 1 by the force of the spring 34.
  • the bolt 23 thereby snaps loaded by the spring 34 into the bolt latch 17. If the ski pole is to be shortened still further, the same procedure is followed, ie the cam 30 is pressed inwards again, and at the same time the pipe is lowered cut 2 pressed against the force of the spring 26 down, that is supported on the ground. The bolt 23 now arrives in the bolt latch 16. The lengthening of the ski pole is therefore triggered only by impulse, ie by briefly pressing the cam 30, and is automatically effected by the spring 26. The ski pole is shortened against the force of the spring 26, so that the ski pole must therefore be supported on the ground in order to shorten it.
  • the illustrated ski pole can be set to three lengths, each ski pole length being lockable and each locked position being releasable by means of the actuating member 24.
  • the illustrated ski pole can therefore be set to three lengths, the pipe sections 1 and 2 being locked in each ski pole length, so that a rigid ski pole but not a resilient ski pole results.
  • This length adjustment of the ski pole can e.g. be very beneficial for a cross-country skier.
  • the ski pole can then be adjusted the shortest in steep terrain, and the longest ski pole would then be used in sloping terrain. In the terrain, you can then use the ski pole with its medium length, whereby this medium length is the normal length of the ski pole, which the cross-country skier would also use if he used a non-adjustable ski pole.
  • the ski stick which is adjustable in three lengths, can also be used for alpine skiing, e.g. for rental floors, e.g. can be rented from a sports shop to different people and thus the length can be adapted to the respective skier.
  • the illustrated ski pole can, however, also be designed in a second exemplary embodiment shown in FIG. 3 in such a way that, in addition to the Ver position on fixed, ie lockable ski pole lengths is also resilient, so that the ski pole between its shortest position and its longest position is resilient.
  • the latch catches are located on only one side with respect to the longitudinal central axis of the ski pole.
  • a rocker arm 22 ' carries a bolt 23'. If the latch 23 'is latched into the latch latch 17', the ski pole has its normal length. If the bolt 23 'is in the bolt latch 18', the ski pole has its greatest length.
  • a tubular component 1 ′′ which has the two locking latches 17 ′ and 18 ′, is in turn fastened to the inner tube section by means of the screw 13.
  • a helical tension spring 26 ' is used, which is therefore between the two pipe sections 1 and 2.
  • One end of the spring 26 ' is supported by pins 37 on the component 1 "and thus on the inner tube section 1.
  • the other end of the spring 26' is supported on a push rod 38 which is mounted on the screw 19. Because this screw 19 is connected to the outer pipe section 2, the aforementioned spring end is supported on the pipe section 2.
  • the tension spring 26 ' is tensioned.
  • the position of the ski pole shown in Fig. 3 is not a rest position , because the compression spring 26 'is stretched to its maximum length, the component 1 "being in contact with the bearing body 20'.
  • the inner pipe section 1 is thus supported on the ground via its ski pole tip, not shown, or via its snow plate, and the cross-country skier presses the outer pipe section 2 against the Force of the spring 26 'at the bottom. If the force exerted by the cross-country skier ceases, the outer tube section 2 springs upwards (the ski pole takes up its greatest length), namely until the loop end 29 ′ abuts the screw 13.
  • this resilient length of the ski pole can be, for example, 70 mm. If this resilient cross-country ski pole is used, it should make running easier for the runner due to its springback; there should be a pushing movement against the ground.
  • the tension spring 26 ' should be harder than the compression spring used in the first embodiment. It has been found in practice that the spring 26 'is so hard that a force of 2-14 kp should be applied in order to bring it into the maximum tensioned position according to FIG. 3.
  • Both exemplary embodiments have in common that the actuating member 24 has only two stable positions, namely the positions shown in FIGS. 1 and 2.
  • the position of the actuating member 24 shown in FIG. 3 is only maintained as long as the skier presses the cam 30 inwards with his finger. As soon as this effort is eliminated, the actuating member 24 returns to its central position shown in FIG. 1.
  • What is different in the two exemplary embodiments, however, is the position of the bolt 23 'when the actuating member 24 has been pressed into the stable position according to FIG. 2.
  • the Rie is gel 23 here in a bolt latch 18, whereas in the second exemplary embodiment according to FIG. 3 the bolt 23 'is held out of the engagement area of a bolt latch.
  • a compression spring 26 or tension spring 26 ' is not a different feature of the two exemplary embodiments, since both exemplary embodiments can in principle be equipped both with a tension spring or with a compression spring. Since a stronger spring is used in the resilient cross-country pole than in the case of a stick that can only be adjusted to fixed lengths, it is advantageous to design this stronger spring as a tension spring, since it cannot buckle and cannot rest against the outer wall. If the ski pole is only adjusted to several fixed lengths, the spring 26 can be relatively weak, since this spring only has to cause the two tube sections 1 and 2 to move apart automatically. For example, according to FIG. 3, it can also be said that a tension spring 26 'has proven itself in practice, which is preloaded at about 3 kp in the idle state. The tension spring 26 'can be screwed relative to its pin 37, which serves as support, so that the effective length of the spring can thereby be varied. As a result, more or fewer turns of the spring can be removed from the spring action.
  • the actuating member As a rotatable cam disk 24, it can also be designed as a longitudinally displaceable pressure pin which, also lying on the back of the ski pole grip, moves transversely to the longitudinal axis of the ski pole bar and acts directly on the rocker arm 22. A head of the pressure pin projects more or less far from the bearing shell 3 and can be pressed more or less far into the interior of the ski pole handle against the force of a spring.
  • a long side of the pressure pin is provided with a locking groove which can be brought into engagement with an immovable locking cam by a slight movement of the pressure pin transversely to its length profile (i.e. in the longitudinal axis of the ski pole).
  • the latter can be designed and arranged as a stationary pin like pin 7 or 35.
  • the aforementioned pressure pin can also be arranged rotated by 90 °, so that the elongated pressure pin now lies in the longitudinal axis or parallel to the longitudinal axis of the ski pole. The pressure pin is then no longer on the back of the ski pole grip, but on the head of the ski pole grip. A mechanical lever (not shown) for the movement connection then lies between the pressure pin arranged in this way and the rocker arm 22.
  • FIGS. 4 and 5 show an improvement which can be applied to the ski poles in FIGS. 1 to 3. It has been shown in practice that it is more expedient if the ski pole is provided with a preselection circuit. This means that the cross-country skier undertakes the desired actuation of the actuating member to adjust the ski pole, but that the ski pole does not have to be supported on the ground at the same time. For example, the cross-country skier can actuate the actuating member when the arm is swung forward; but it is only when the ski pole is subsequently pushed off the ground that the ski pole is converted. This does not affect the rhythmic movement during cross-country skiing.
  • FIGS. 4 and 5 those components which correspond to the components shown in FIGS. 1 to 3 are provided with the same reference number, which has been expanded by one hundred.
  • the ski pole has an inner tube section 101, i.e. the actual pole. There is also an outer tube section 102 that is part of the handle. In the outer pipe section 102 there is a bushing 120 with a bearing 121 for a two-armed rocker arm 122. One rocker arm carries a bolt 123. On the outer pipe section 102 there is a fitting 104, on which a rocker arm spring 134 is supported. This rocker arm spring 134 is supported with its other end on the other arm of the rocker arm 122.
  • An actuator 124 is pivotable about a bearing journal 107 mounted in the fitting 104.
  • the actuating member 124 is designed as a cam disk and has cams 132 and 133 which can come into engagement with the rocker arm 122.
  • the inner tube section 101 is provided with three locking latches 116, 117 and 118 '.
  • the ski pole still has a grip shell 103 made of plastic.
  • the ski pole shown schematically in FIGS. 4 and 5 corresponds to the design of the ski pole according to FIGS. 1 to 3.
  • the actuator 124 has a different design.
  • the actuating member 124 has only a single manually operated cam 42. There are therefore no longer two cams corresponding to cams 30 and 31 in FIGS. 1 to 3. In Figures 4 and 5, only two different positions of the actuator 124 are shown.
  • the rocker arm 122 lies in a recess 41 between the two cams 132 and 133. 5, the rocker arm 122 is acted on via the cam 132.
  • a third position, not shown, of the actuating member 124 would now be conceivable, in which the rocker arm 122 is acted on via the cam 133.
  • This latter type of actuation can be present in one embodiment of the Skistokkes; however, an embodiment is also possible in which this third position of the actuating member 24 is not used and thus cannot be assumed by a built-in lock. In the case shown, the actuator 124 should therefore only be able to assume the two positions shown.
  • the ski pole shown in FIGS. 4 and 5 is provided with a spring-elastic preselector 39.
  • This is designed as a leaf spring.
  • This leaf spring 39 is attached to the rocker arm 122 at the point 40.
  • the preselector 39 is thus present in the rocker arm associated with the actuator 124. It can also be said that the preselector 39 is located between the actuator 124 and the bolt 123.
  • the rocker arm 122 is constantly pressed against the actuating member 124 by the rocker arm spring 134 via the preselector 39.
  • the actuating member 124 can assume the two fixed positions shown in FIGS. 4 and 5 in the manner of a snap switch.
  • the spring-elastic pre-selection element 39 has the effect that the actuating element 124 can be moved into a changed position without this having to result in an immediate adjustment of the rocker arm 122.
  • the rocker arm 122 is in the same position, although the actuator 124 is in two different positions.
  • the position of the rocker arm 122 shown in FIG. 5 is of course only maintained as long as the inner tube section 101 exerts such a rightward force on the bolt 123 which exceeds the force stored in the spring 39.
  • the aforementioned force exerted by the inner tube section 101 on the bolt 123 is brought about by the spring 26 or 26 ', which is shown in FIGS. 1-3. This spring tends to move the two pipe sections 101 and 102 axially apart.
  • the ski pole shown in FIG. 5 can be used in two ways.
  • One as a short stick in which the two pipe sections 101 and 102 are completely shifted into one another and the bolt 123 lies in the bolt latch 117, with the actuating member 124 in the position according to FIG. 4, and the other time as a resilient stick, whereby the rocker arm 122 is approximately parallel to the push rod 138, so that the bolt 123 is outside the engagement area of the bolt latch le 117 and the actuator 124 is in the position shown in FIG. 5.
  • the actuator 124 is pushed down in the longitudinal direction of the ski pole, which means a desired short rigid pole. If this stick is supported on the floor, the two pipe sections 101 and 102 are increasingly shifted into one another.
  • the rocker arm 121 is provided with a run-up ramp 43 upstream of the bolt 123 for the inner tube section 101.
  • the end face of the pipe section 101 facing the run-up ramp 43 meets the ramp 43, so that the rocker arm 122 is pivoted clockwise against the force of the spring 134, so that the pipe section 101 can reach the position according to FIG. 5.
  • the bolt 123 is snapped into the bolt latch 117, the actuator having the position shown in FIG.
  • a short rigid stick and a resilient stick have been explained with reference to FIGS. 4 and 5 and when using a strong spring, preferably a tension spring.
  • a strong spring preferably a tension spring.
  • a long rigid stick can also be achieved in this way.
  • a weak spring which is only used to change the pole to the different lengths and not to use the spring energy when cross-country skiing, then e.g. a short rigid stick, a medium-length rigid stick and a long rigid stick are formed.
  • the bolt 123 can lie on both sides of the rocker arm, so that the bolt latches in FIGS. 4 and 5 are then also present in the lower wall of the tube section 101.
  • the ski pole can be made lighter, since with the same total length of the ski pole, the tube sections 101 and 102 can be moved axially further apart, that is, they can themselves be shorter, since the rocker arm 122 in the position according to FIG 4 can, so to speak, be threaded into the pipe section 101.
  • the rocker arm 122 is pivotable about the pin 119.
  • the resilient preselector could itself be formed by the rocker arm 122.
  • the rocker arm 122 itself is designed as a leaf spring. The separate leaf spring 39 then no longer has to be present. If the rocker arm 122 itself is a leaf spring, then one leaf spring arm carries the bolt 123 and the other leaf spring arm lies in the area of engagement of the actuating member 124.
  • This position of the actuator 124 is not a rest position, so it is only taken as long as the finger acts on the actuator 124, as in the position of the actuator 24 shown in FIG. 3.
  • the actuator 124 is desired by the cross-country skier that the length of the ski pole should be changed, i.e. from an existing short position to a long position or from an existing long position to a short position. If an adjustment from an existing short position to a long position is desired, this extension is used immediately through the existing spring 26 (Fig. 1, 2) performed. The cross-country skier must then immediately release the actuating member 124, which then returns to the rest position shown in FIG. 4, so that the latch 123 can snap into the respective latch latch in the long position of the ski pole.
  • the ski pole is adjusted from an existing long position to a short position, the ski pole is of course only shortened when the pole is used, ie when the ski pole is supported on the ground.
  • the cross-country skier must release the actuating member 124 again so that it returns to the position shown in FIG. 4 and the latch 123 can snap into the respective latch latch. If the cross-country skier forgets to let go of the actuating member 124 in time, the bolt 123 is not released for snapping into the respective bolt latch and the desired shortening of the ski pole is not carried out.
  • the inner tube section 101 can be provided with a nose, not shown, which is embossed, for example, from the wall of this tube section 101 and between the two latch latches 116 and 117 in the way of latch 123. So if the bolt 123 could not snap into the bolt latch 116 because the actuator 124 was not released by the cross-country skier in time, the ski stick only returns a little to its long position until the bolt 123 bears against the aforementioned nose. This nose mentioned thus had a stop shoulder for the bolt 123 on the right in FIG. 4. When the next stick is used, when the inner tube section 101 is supported on the ground, the inner tube portion 101 is moved to the left in FIG. 4, so that the bolt then 123 can snap into the latch latch 116.
