Abstract

Bei Fersenhaltern für Sicherheitsskibindungen besteht das Problem, daß bei einer Auslösung des Vorderbackens der Sohenhalter geschlossen bleibt, so daß Skifahrer zum erneuten Anlegen der Bindung den Sohlenhalter mittels eines Auslösehebels von Hand aus öffnen muß. Zur Lösung dieses Problems ist bei einem Fersenhalter, der einen auf einer skifesten Führungsschiene (2) gegen die Kraft zumindest einer Schubfeder (5) verschiebbaren Lagerbock (7) und eine von einer Feder (15), welche in einem Federgehäuse (13) angeordnet ist, beaufschlagte, den Sohlenhalter (8) in der Abfahrtsstellung haltende Sperrklinke (12) aufweist, vorgesehen, am skifesten Widerlager (6) der Schubfeder(n) (5) zumindest einen Steuerteil (10,10') zu befestigen oder anzulenken, der bei einer Auslösung durch den Vorderbacken das Federgehäuse (13) von seiner Abstützfläche (12b) an der Sperrklinke (12) wegdrückt.The problem with heel holders for safety ski bindings is that when the toe is released, the sole holder remains closed, so that skiers have to open the sole holder manually by means of a release lever in order to put the binding on again. To solve this problem, a heel holder has a bearing block (7) which can be displaced on a ski-fixed guide rail (2) against the force of at least one thrust spring (5) and one of a spring (15) which is arranged in a spring housing (13) , acted upon, the pawl (12) holding the sole holder (8) in the downhill position, provided to fasten or articulate at least one control part (10, 10 ') on the ski - fixed abutment (6) of the thrust spring (s) (5), which at a release by the front jaw presses the spring housing (13) away from its support surface (12b) on the pawl (12).

Description

Die Erfindung betrifft einen Fersenhalter für Sicherheitsskibindungen mit einer auf einer skifesten Führungsschiene gegen die Kraft zumindest einer Schubfeder verschiebbar geführten, einen Lagerbock tragenden Grundplatte, an welchem Lagerbock ein Sohlenhalter schwenkbar angeordnet ist, der mittels einer an der einen Seite an einer Steuerfläche abgestützten, an der anderen Seite von einer Feder, die in einem schwenkbar gelagerten Federgehäuse angeordnet ist, beaufschlagten Sperrklinke in der Abfahrtsstellung gehalten ist.The invention relates to a heel holder for safety ski bindings with a base plate, which is displaceably guided on a ski-fixed guide rail against the force of at least one thrust spring, and on which bearing block a sole holder is pivotably arranged, which is supported on one side on a control surface by means of a on the other side, a pawl which is acted upon by a spring which is arranged in a pivotably mounted spring housing is held in the downward position.

Ein Fersenhalter der eingangs genannten Art ist beispielsweise in der AT-PS 327.068 beschrieben und auch durch einige am Markt befindliche Produkte bekannt. Diese Fersenbindungen haben sich in der Praxis gut bewährt und sind für den Benützer komfortabel zu handhaben, weisen jedoch den Nachteil auf, daß bei einer Auslösung des Vorderbackens, beispielsweise bei einem Drehsturz, der Sohlenhalter geschlossen bleibt, so daß der Skifahrer zum erneuten Anlegen der Bindung diesen mittels eines Auslösehebels von Hand aus öffnen muß.A heel holder of the type mentioned at the outset is described, for example, in AT-PS 327.068 and is also known from some products on the market. These heel bindings have proven themselves in practice and are comfortable for the user to handle, but they have the disadvantage that when the toe is released, for example in the event of a lintel fall, the sole holder remains closed, so that the skier can put on the binding again this must be opened by hand using a release lever.

Die Erfindung hat sich daher die Aufgabe gestellt, einen Fersenhalter der eingangs genannten Art weiterzuentwickeln, so daß er auch nach einer Auslösung des Vorderbackens einsteigbereit ist.The object of the invention is therefore to further develop a heel holder of the type mentioned at the outset, so that it is ready for entry even after the toe piece has been triggered.

Gelöst wird die gestellte Aufgabe erfindungsgemäß dadurch, daß am skifesten Widerlager der Schubfeder(n) zumindest ein Steuerteil befestigt oder angelenkt ist, welcher eine Aussparung der Grundplatte durchsetzt und welcher bei Entlasten der Schubfeder(n) ohne Fersenauslösung das Federgehäuse von seiner Abstützfläche an der Sperrklinke wegdrückend beaufschlagt.The object is achieved according to the invention in that at least one control part is fastened or articulated to the ski-fixed abutment of the thrust spring (s), which passes through a recess in the base plate and which at Ent load the thrust spring (s) without heel release pressing the spring housing away from its support surface on the pawl.

Durch die erfindungsgemäßen Maßnahmen wird das gesetzte Ziel einwandfrei erreicht. Bei einer reinen Vorderbackenauslösung beaufschlagt der Steuerteil während der Entlastung der Schubfeder(n), welcher Vorgang ein Verschieben des Fersenhalters in Richtung zur Skispitze bewirkt, das Federgehfuse drückt diesen von seiner Abstützfläche an der Sperrklinke weg, die nun selbst von der Steuerfläche freikommt, so daß der Sohlenhalter in die Offenstellung verschwenken kann, der Fersenhalter ist einsteigbereit.With the measures according to the invention, the goal set is achieved perfectly. In the case of a pure toe-jaw release, the control part acts upon the relieving of the thrust spring (s), which process causes the heel holder to move towards the tip of the ski, the spring casing pushes it away from its support surface on the pawl, which is now released from the control surface, so that the sole holder can pivot into the open position, the heel holder is ready to step on.

Auch ist es erfindungsgemäß von Vorteil, wenn der Steuerteil am skifesten Widerlager in einem Bereich von der Skiebene weg hochschwenkbar ist und von einer Rückholfeder, welche vorzugsweise eine Schenkelfeder ist, in seiner Ruhelage gehalten ist. Auf diese Weise wird die zwischen dem Federgehäuse und dem Steuerteil auftretende Reibung wirkungsvoll vermindert.It is also advantageous according to the invention if the control part on the ski-fixed abutment can be swung up in an area away from the ski plane and is held in its rest position by a return spring, which is preferably a leg spring. In this way, the friction occurring between the spring housing and the control part is effectively reduced.

Ein weiteres Merkmal der Erfindung besteht darin, daß jeder Steuerteil eine Steuernase aufweist, welche bei geschlossenem Fersenhalter, sowohl in entspannter als auch in vorgespannter Lage der Schubfeder(n) in je einer Rastvertiefung des Federgehäuses zum Liegen kommt, welche Rastvertiefungen in Skilängsrichtung hintereinander angeordnet sind und zwischen welchen Rastvertiefungen eine in Richtung zur Skioberseite weisende Steuernocke vorgesehen ist. Die eine Rastvertiefung gewährleistet ein ungehindertes Schließen des Fersenhalters auch ohne eingesetzten Skischuh, die zweite dient zur Aufnahme des Steuerteiles bei in die Bindung eingesetztem Skischuh. Die zwischen diesen Rastvertiefungen angeordnete Steuernocke wird bei einer reinen Auslösung des Vorderbacknes von der Steuernase des Steuerteiles beaufwird schlagt, wodurch das Federgehäuse angehoben/und von seiner Abstützfläche an der Sperrklinke freikommt.Another feature of the invention is that each control part has a control lug, which comes to rest when the heel holder is closed, both in the relaxed and in the pretensioned position of the thrust spring (s) in one detent depression of the spring housing, which detent depressions are arranged one behind the other in the longitudinal direction of the ski and between which locking recesses a control cam pointing in the direction of the top of the ski is provided. One locking recess ensures an unimpeded closing of the heel holder even without a ski boot inserted, the second serves to hold the control part when the ski boot is inserted into the binding. The between these recesses The arranged control cam is struck when the front jaw is triggered by the control lug of the control part, as a result of which the spring housing is raised / and is released from its support surface on the pawl.

Eine besonders vorteilhafte Ausgestaltung der Erfindung ist dann gegeben, wenn das skifeste Widerlager, wie an sich bekannt, von einer Gabel gebildet ist, die in an sich bekannter Weise einerends einen Steg zur Abstützung der Schubfeder(n) aufweist und anderends mit einer zum Ver- bzw. Entrasten mit der Führungsschiene vorgesehenen Raste versehen ist, und daß der bzw. die Steuerteil(e) an den Schenkeln der Gabel befestigt bzw. angelenkt ist bzw. sind. Auf diese Weise ist eine Anordnung des Steuerteiles an vielen bekannten auch am Markt befindlichen Fersenhaltern mit geringstem baulichen Aufwand gewährleistet.A particularly advantageous embodiment of the invention is given when the ski-fixed abutment, as is known per se, is formed by a fork which, in a manner known per se, has a web on one end for supporting the thrust spring (s) and on the other hand with a or unlocking is provided with the guide rail provided, and that the control part (s) is or are attached to the legs of the fork. In this way, an arrangement of the control part on many known heel holders, which are also on the market, is ensured with the least constructional effort.

Weitere Merkmale, Vorteile und Einzelheiten der Erfindung werden nun anhand der Zeichnung, die zwei Ausführungsbeispiele darstellt, näher beschrieben. Es zeigen: die Fig.l bis 4 ein erstes Ausführungsbeispiel eines erfindungsgemäßen Fersenhalters, Fig.l den erfindungsgemäßen Fersenhalter in Seitenansicht im Schnitt in geschlossener Lage ohne eingesetzten Skischuh, Fig.2 den Rastmechanismus des Fersenhalters in vergrößertem Maßstab ebenfalls in Seitenansicht im Schnitt in einer Lage ohne eingesetzten Skischuh, die Fig.3 den Rastmechanismus ähnlich zu Fig.2 jedoch in seiner Lage mit eingesetztem Skischuh, Fig.4 eine Lage des Rastmechanismus während einer Sicherheitsauslösung des (nicht dargestellten) Vorderbackens und Fig.5 ein zweites Ausführungsbeispiel in einer ähnlichen Darstellung wie Fig.2.Further features, advantages and details of the invention will now be described with reference to the drawing, which shows two exemplary embodiments. 1 to 4 show a first exemplary embodiment of a heel holder according to the invention, FIG. 1 shows the heel holder according to the invention in a side view in section in the closed position without a ski boot inserted, FIG. 2 shows the locking mechanism of the heel holder in an enlarged scale also in a side view in section in one Position without inserted ski boot, FIG. 3 shows the locking mechanism similar to FIG. 2 but in its position with inserted ski boot, FIG. 4 a position of the locking mechanism during a safety release of the toe (not shown) and FIG. 5 a second exemplary embodiment in a similar manner Representation like Fig. 2.

Wie aus Fig.1 ersichtlich ist, ist auf der Oberseite eines Skis 1 eine Führungsschiene 2 mittels (nicht dargestellter) Schrauben befestigt. Auf der Führungsschiene 2 ist eine Grundplatte 3 des Fersenhalters in der Längsrichtung des Skis 1 verschiebbar geführt und in an sich bekannter Weise zur Anpassung der Bindung an unterschiedlich lange Skischuhe in der jeweils gewünschten Lage verrastbar. In einer Aussparung 3a der Grundplatte 3 ist eine Schubfeder 5 angeordnet, deren eines Ende an einem Stützteil 3b der Grundplatte 3 und deren anderes Ende an einem Quersteg einer als skifestes Widerlager 6 dienenden Gabel abgestützt ist, die mittels zweier Anzeigezapfen 6a den Rand der Aussparung 3a übergreift. Der Fersenhalter ist somit gegen die Kraft der Schubfeder 5 auf der Führungsschiene 2 verschiebbar geführt. Die Anzeigezapfen 6a dienen im Zusammenhang mit einer an der Grundplatte 3 befindlichen Skala bei in die Bindung eingesetztem Skischuh zum Ablesen des Anpreßdruckes des Fersenhalters gegen den (nicht dargestellten) Vorderbacken. Das Widerlager 6 weist zwei seitlich der Schubfeder 5 und parallel zur Längsachse des Skis 1 verlaufende Schenkel 6b auf, die in dem dem Quersteg des Widerlagers 6 abgewandten Ende der Aussparung 3a der Grundplatte 3 zu einer Rastzunge zusammenlaufend gestaltet sind, welche in bekannter und daher nicht dargestellter Weise zum Verrasten des Fersenhalters an der Führungsschiene 2 vorgesehen ist. Zumindest einer der beiden Schenkel 6b des Widerlagers 6 trägt einen Steuerteil 10, der die Aussparung 3a der Grundplatte 3 von unten her durchsetzt und auf dessen Gestalt und Wirkungsweise noch eingegangen wird.As can be seen from FIG. 1, a guide rail 2 is fastened to the top of a ski 1 by means of screws (not shown). On the guide rail 2, a base plate 3 of the heel holder is displaceably guided in the longitudinal direction of the ski 1 and, in a manner known per se, can be locked in the desired position in order to adapt the binding to ski boots of different lengths. In a recess 3a of the base plate 3, a thrust spring 5 is arranged, one end of which is supported on a support part 3b of the base plate 3 and the other end of which is supported on a crossbar of a fork serving as a ski abutment 6, which fork uses two indicator pins 6a to support the edge of the recess 3a spreads. The heel holder is thus guided against the force of the thrust spring 5 on the guide rail 2. The indicator pins 6a are used in conjunction with a scale located on the base plate 3 when the ski boot is inserted into the binding for reading the contact pressure of the heel holder against the toe (not shown). The abutment 6 has two legs 6b extending to the side of the thrust spring 5 and parallel to the longitudinal axis of the ski 1, which are designed in the end of the cutout 3a of the base plate 3 facing away from the transverse web of the abutment 6 to form a locking tongue, which are known and therefore not shown way is provided for locking the heel holder on the guide rail 2. At least one of the two legs 6b of the abutment 6 carries a control part 10, which passes through the cutout 3a of the base plate 3 from below and the shape and mode of operation of which will still be discussed.

Auf der Grundplatte.3 ist ein Lagerbock 7 befestigt, an dem ein Sohlenhalter 8 um eine Achse 9 schwenkbar gelagert ist. Der Sohlenhalter 8 trägt auf einer weiteren, parallel zur erstgenannten verlaufenden Achse 11 eine ebenfalls verschwenkbare Sperrklinke 12,welche in der Abfahrtsstellung des Fersenhatlers mittels einer Rastnase 12a eine Raste 17a einer am Lagerbock 7 ausgebildeten Steuerfläche 17 untergreift. Weiters ist auf der Schwenkachse 9 des Sohlenhalters 8 ein, in Draufsicht betrachtet, etwa U-förmiges Federgehäuse 13 gelagert, welcher in seinen beiden Seitenwangen Längsschlitze 13a aufweist, die eine Führung für einen Sperrteil 14 bilden. Der Sperrteil 14 ist von dem einen Ende einer Auslösefeder 15 beaufschlagt, deren anderes Ende an einem Federwiderlager 16 abgestützt ist, das mittels einer drehbar im Federgehäuse 13 gelagerten Schraube 28 in der Achsrichtung der Auslösefeder 15 verstellbar ist.On the base plate. 3, a bearing block 7 is fastened, on which a sole holder 8 is pivotally mounted about an axis 9. The sole holder 8 supports another, parallel to The first-mentioned extending axis 11 is a pawl 12 which can also be pivoted and which, in the downward position of the heel hatcher, engages under a catch 17a of a control surface 17 formed on the bearing block 7 by means of a detent 12a. Furthermore, viewed in plan view, an approximately U-shaped spring housing 13 is mounted on the pivot axis 9 of the sole holder 8 and has longitudinal slots 13 a in its two side cheeks, which form a guide for a locking part 14. The locking part 14 is acted upon by one end of a release spring 15, the other end of which is supported on a spring abutment 16 which is adjustable in the axial direction of the release spring 15 by means of a screw 28 rotatably mounted in the spring housing 13.

Die Sperrklinke 12 bildet für den Sperrteil 14 eine Raste 12b, in welche dieser durch die Auslösefeder 15 gedrückt wird. Im Anschluß an die Raste 12b ist an der Sperrklinke 12 eine Ausnehmung 12c vorgesehen, die als Freistellung dient, und in welche bei Betätigen eines Auslösehebels 18 der Sperrteil 14 einrastet.The pawl 12 forms a catch 12b for the locking part 14, into which it is pressed by the release spring 15. Following the catch 12b, a recess 12c is provided on the pawl 12, which serves as an exemption, and into which the locking part 14 engages when a release lever 18 is actuated.

Der Auslösehebel 18 übergreift seitlich den Sohlenhalter 8 und ist an der am Sohlenhalter 8 angeordneten Achse 11 schwenkbar gelagert, an welcher Achse 11 auch die Sperrklinke 12 angelenkt ist. Ein Bolzen 19 ist parallel zur Achse 11 verlaufend am Auslösehebel 18 befestigt, durchsetzt sowohl den Sohlenhalter 8 als auch die Seitenwände des Federgehäuses 13 und ist in diesen beiden Bauteilen jeweils in Langlöchern 8b,13b gleitbeweglich geführt. Hiebei sind die beiden am Sohlenhalter 8 vorgesehenen Langlöcher 8b konzentrisch zur Schwenkachse 11 angeordnet, die beiden am Federgehäuse 13 ausgebildeten Langlöcher 13b sind etwa im rechten Winkel zur Längserstreckung der Langlöcher 8b des Sohlenhalters 8 angeordnet. Bei einem Hochschwenken des Auslösehebels 18 gleitet der Bolzen 19 in den Langlöchern 8b des Sohlenhalters 8 nach oben und verschwenkt unter gleichzeitigem Gleiten in den Langlöchern 13b des Federgehäuses 13 in Richtung zur Skispitze, dieses um die Achse 9 ebenfalls nach oben. Dadurch kommt der Sperrteil 14 außer Eingriff von der Raste 12b der Sperrklinke 12, wodurch die Sperrklinke 12 frei verschwenken kann und ihre Rastnase 12a von der Raste 17a der Steuerfläche 17 des Lagerbockes 7 freikommt, der Sohlenhalter 8 verschwenkt, unterstützt von einer an der Achse 9 angeordneten Öffnungsfeder 20, in die Offenstellung.The release lever 18 laterally overlaps the sole holder 8 and is pivotably mounted on the axis 11 arranged on the sole holder 8, on which axis 11 the pawl 12 is also articulated. A bolt 19 is mounted parallel to the axis 11 on the release lever 18, passes through both the sole holder 8 and the side walls of the spring housing 13 and is slidably guided in each of these two components in elongated holes 8b, 13b. The two elongated holes 8b provided on the sole holder 8 are arranged concentrically to the pivot axis 11, the two elongated holes 13b formed on the spring housing 13 are approximately at right angles to the longitudinal extent of the elongated holes 8b of the Sole holder 8 arranged. When the release lever 18 is pivoted up, the bolt 19 slides upward in the elongated holes 8b of the sole holder 8 and pivots while simultaneously sliding in the elongated holes 13b of the spring housing 13 in the direction of the ski tip, and this also upwards about the axis 9. As a result, the locking part 14 disengages from the catch 12b of the pawl 12, as a result of which the pawl 12 can pivot freely and its catch 12a is released from the catch 17a of the control surface 17 of the bearing block 7, the sole holder 8 pivots, supported by one on the axis 9 arranged opening spring 20, in the open position.

Der am Schenkel 6b des Widerlagers 6 befestigte Steuerteil 10 weist eine Steuernase 10a auf, die in der geschlossenen Lage des Sohlenhalters 8 und bei nicht eingesetztem Skischuh in einer Rastvertiefung 13c der zugehörigen Seitenwand des Federgehäuses 13 zum Liegen kommt. Diese Rastvertiefung 13c ist an der unteren Kante dieser Seitenwand ausgebildet (siehe Fig.2). Während des Einsteigens in den Fersenhalter mittels eines Skischuhes verschiebt dieser den Fersenhalter gegen die Kraft der Schubfeder 5 auf der skifesten Führungsschiene 2 in Richtung zum Skiende, wobei nach erfolgtem Niederschwenken des Sohlenhalters 8 der dem Ski 1 gegenüber ortsfest verbleibende Steuerteil 10 mit seiner Steuernase 10a in einer weiterenebenfalls an der unteren Kante der Seitenwand des Federgehäuses 13 ausgebildeten Rastvertiefung 13d zum Liegen kommt.The control part 10 fastened to the leg 6b of the abutment 6 has a control lug 10a which comes to rest in the closed position of the sole holder 8 and when the ski boot is not inserted in a recess 13c in the associated side wall of the spring housing 13. This locking recess 13c is formed on the lower edge of this side wall (see Fig.2). While stepping into the heel holder by means of a ski boot, the latter moves the heel holder against the force of the thrust spring 5 on the ski-fixed guide rail 2 in the direction of the end of the ski, the control part 10 remaining stationary with the control nose 10a in after the sole holder 8 has been pivoted downward a further latching recess 13d also formed on the lower edge of the side wall of the spring housing 13 comes to rest.

Erfolgt nun bei einem Sturz des Skifahrers, beispielsweise bei einem Drehsturz, ein Auslösen des (nicht dargestellten) Vorderbackens, so wird der Fersenhalter durch die sich entspannende Schubfeder 5 auf der Führungsschiene 3 in Richtung zum Vorderbacken verschoben. Hiebei beaufschlagt die Steuernase 10a des Steuerstückes 10 eine zwischen den beiden Rastvertiefungen 13c,13d ausgebildete Steuernocke 13e des Federgehäuses 13 und drückt das Federgehäuse 13 nach oben u.zw. um jenes Ausmaß, das erforderlich ist, um den im Federgehäuse 13 gelagerten Sperrteil 14 aus der Raste 12a der Sperrklinke 12 zu heben (siehe Fig.4). Die Sperrklinke 12 ist nun nicht mehr von der Auslösefeder 15 beaufschlagt. Der Öffnungsvorgang des Sohlenhalters 8 erfolgt von der Öffnungsfeder 20 unterstützt in der schon beschriebenen, auch beim willkürlichen Öffnen stattfindenden Weise. Der Fersenhalter ist einsteigbereit, das erneute Einsteigen in die Bindung erfolgt auf an sich bekannte Weise entweder durch Schließen des Auslösehebels 18 und anschließendes Niederschwenken des Sohlenhalters 8 mit dem Skischuh oder dadurch, daß zuerst der Sohlenhalter 8 und anschließend der Auslösehebel 18 verschwenkt wird.If the toe piece (not shown) is triggered when the skier falls, for example during a turning fall, the heel holder is moved in the direction by the relaxing thrust spring 5 on the guide rail 3 shifted to toe. Here, the control lug 10a of the control piece 10 acts on a control cam 13e of the spring housing 13 formed between the two locking recesses 13c, 13d and presses the spring housing 13 upwards and so on. to the extent that is required to lift the locking part 14 mounted in the spring housing 13 out of the catch 12a of the locking pawl 12 (see FIG. 4). The pawl 12 is no longer acted upon by the release spring 15. The opening process of the sole holder 8 is supported by the opening spring 20 in the manner already described, which also takes place during the arbitrary opening. The heel holder is ready for boarding, the re-entry into the binding is carried out in a manner known per se either by closing the release lever 18 and then swiveling the sole holder 8 down with the ski boot, or by first pivoting the sole holder 8 and then the release lever 18.

Der in Fig.5 dargestellte Steuerteil 10' ist am Schenkel 6b des Widerlagers 6 von der Skiebene weg schwenkbar angelenkt und von einer Schenkelfeder 21 in seiner in dieser Fig. dargestellten Lage gehalten. Diese Ausbildung bringt den Vorteil mit sich, daß der Steuerteil 10' in einem Bereich (begrenzt durch einen nicht dargestellten Anschlag) schwenken kann, wodurch die zwischen dem Federgehäuse 13 und dem Steuerteil 10' auftretende Reibung vermindert ist.The control part 10 ′ shown in FIG. 5 is pivotably articulated on the leg 6b of the abutment 6 away from the ski plane and is held in its position shown in this figure by a leg spring 21. This design has the advantage that the control part 10 'can pivot in a region (limited by a stop, not shown), whereby the friction occurring between the spring housing 13 and the control part 10' is reduced.

Die Erfindung ist auf die dargestellten Ausführungsbeispiele nicht eingeschränkt. Es sind weitere Abwandlungen denkbar, ohne den Rahmen des Schutzumfanges zu verlassen. So kann eine Vielzahl von Fersenbindungen, deren Kraftpaket eine =,Steuerfläche beaufschlagt und von dieser wegirückbar ist mit geringen Aufwand mit dem erfindungsgemäßen Steuerteil versehen werden. Auch ist es selbstverständlich, zwei anstelle von einer einzigen Schubfeder vorzusehen.The invention is not restricted to the exemplary embodiments shown. Further modifications are conceivable without leaving the scope of the scope of protection. Thus, a large number of heel bindings, the power pack of which acts on a control surface and can be moved away from it with little effort using the control part according to the invention be provided. It is also a matter of course to provide two shear springs instead of one.
