Description

Die Erfindung bezieht sich auf eine Bügelschnalle zum Verschließen von Skischuhen, mit einer mit dem Skischuh fest verbundenen Grundplatte, an der ein im Querschnitt U-förmiger Schnallenhebel mit seiner Achse schwenkbar gelagert ist, der zwischen einer Offen- und einer Schließlage verschwenkbar ist und der mit einem Zylinder verbunden ist, dessen Achse parallel zur Hebelachse verläuft und in dessen mit einem Gewinde versehener Querbohrung eine Schraube bzw. eine Gewindehülse, welche mit einem den Skischuh verschließenden Element verbunden ist, gelagert ist, wobei der Zylinder in Längsrichtung des Schnallenhebels in mindestens zwei Relativlagen einstellbar ist, wobei in den beiden Schenkeln des Schnallenhebels zwei in dessen Längsrichtung verlaufende Langlöcher ausgespart sind, in denen die Enden der Achse des Zylinders geführt sind, und wobei die über die Langlöcher nach außen vorstehenden Enden der Achse in den Schenkein einer im Querschnitt ebenfalls U-förmigen Klappe gelagert sind.The invention relates to a strap buckle for closing ski boots, with a base plate firmly connected to the ski boot, on which a cross-sectionally U-shaped buckle lever is pivotally mounted with its axis, which is pivotable between an open and a closed position and with a cylinder is connected, the axis of which runs parallel to the lever axis and a screw or a threaded sleeve, which is connected to an element closing the ski boot, is mounted in its threaded transverse bore, the cylinder being in the longitudinal direction of the buckle lever in at least two relative positions is adjustable, wherein in the two legs of the buckle lever two slots extending in its longitudinal direction are recessed, in which the ends of the axis of the cylinder are guided, and wherein the ends of the axis projecting outward through the slots in the legs are also U in cross section -shaped flap are stored.

Eine derartige Bügelschnalle ist bereits bekannt und in dem DE-U-1910435 beschrieben. Diese Schnalle hatte den Nachteil, daß an die der Schnalle gegenüberliegende andere Seite des Schuhschaftes eine Platte angenietet war, an der eine Schlaufe mit einem Außensteg unt mit mindestens einem Zwischensteg angelenkt war. In diese Schlaufe konnte das hakenförmige Ende des Spannhebels eingesetzt werden.Für das Spannen eines Seiles, wie es bei Skischuhen heute vielfach verwendet wird, ist diese Bügelschnalle nicht geeignet, da sich die Elemente für die Grob- und die für die Feineinstellung auf zwei verschiedenen Teilen befanden.Such a buckle is already known and described in DE-U-1910435. This buckle had the disadvantage that a plate was riveted to the other side of the shoe upper opposite the buckle, to which a loop with an outer web and at least one intermediate web was articulated. The hook-shaped end of the tensioning lever could be inserted into this loop. This strap buckle is not suitable for tensioning a rope, as is often used for ski boots today, since the elements for the coarse and for the fine adjustment are on two different parts found.

Die EP-A1 0300 955 beschreibt zwar eine Bügelschnalle für Seilverschlüsse, doch ist diese Ausführungsform infolge der vielen Einzelteile in ihrem Aufbau sehr kompliziert und daher kostenaufwendig in ihrer Herstellung. Außerdem werden zwei Seilenden gleichzeitig gespannt, was den vom Skiläufer aufzubringenden Kraftaufwand verdoppelt.Although EP-A1 0300 955 describes a strap buckle for rope closures, this embodiment is very complicated in its construction due to the large number of individual parts and therefore costly to produce. Also be two rope ends tensioned at the same time, which doubles the effort required by the skier.

Der Spannhebel nach der CH-PS 410 681 ist dem an erster Stelle genannten ähnlich. Auch hier sind zwei Teile vorhanden, welche auf beiden einander gegenüberliegenden Seiten eines Schuhschaftes angenietet sind. Der eine Teil besteht aus einer Platte mit mehreren Haken, die der Grobverstellung dienen, wogegen am anderen gegenüberliegenden Teil ein Spannhebel angelenkt ist, welcher die Elemente der Feineinstellung aufnimmt. Auch diese Ausführung hat den Nachteil, daß sich die Elemente für die Feineinstellung und die für die Grobeinstellung auf zwei einander gegenüberliegenden Teilen befinden, was die Verwendung eines Spannseiles ausschließt.The tensioning lever according to CH-PS 410 681 is similar to that mentioned in the first place. Here, too, there are two parts that are riveted on both opposite sides of a shoe upper. One part consists of a plate with several hooks, which are used for the rough adjustment, whereas a tension lever is articulated on the other opposite part, which receives the elements of the fine adjustment. This embodiment also has the disadvantage that the elements for fine adjustment and for coarse adjustment are located on two opposite parts, which precludes the use of a tension cable.

Die Erfindung stellt sich die Aufgabe, die Nachteile der bekannten Ausführungen zu beseitigen und eine Bügelschnalle zu schaffen, die einfach in ihrem Aufbau ist und bei der sich die Elemente für die Grob- und die Feineinstellung an einem Bauteil befinden.The object of the invention is to eliminate the disadvantages of the known designs and to provide a strap buckle which is simple in its construction and in which the elements for the coarse and fine adjustment are located on one component.

Ausgehend von einer Bügelschnalle gemäß dem ersten Teil des Anspruches 1 wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß die Klappe in mindestens zwei Lagen, in welchen sie am Schnallenhebel anliegt, gegenüber diesem verrastbar ist, und daß die Schraube bzw. die Gewindehülse unmittelbar fest mit einem den Skischuh verschließenden Seil verbunden ist. Dadurch, daß sich die Befestigungsstelle des Seiles im Inneren des Schnallenhebels befinden, ist diese Stelle gegen Beschädigungen bzw. Verschmutzungen weitgehend geschützt.Starting from a strap buckle according to the first part of claim 1, this object is achieved in that the flap can be locked in at least two positions in which it rests on the buckle lever, and that the screw or the threaded sleeve is directly fixed to one the rope closing the ski boot is connected. Characterized in that the fastening point of the rope is inside the buckle lever, this point is largely protected against damage or contamination.

An sich wäre es denkbar, an der Unterseite des Steges der Klappe einen Rastzahn anzuordnen, der in eine von mehreren im Steg des Schnallenhebels ausgesparten Bohrungen eingreift. Dies würde aber die Herstellung der Bügelschnalle kompliziert gestalten. Zur Vereinfachung der Produktion sieht gemäß dem Anspruch 2 die Erfindung daher vor, daß die Klappe in jeder verrasteten Lage von mindestens einer an der Oberseite des Schnallenhebels angeordneten Rastnase zumindest in Richtung des Zuges des Seiles festgehalten ist.As such, it would be conceivable to arrange a locking tooth on the underside of the web of the flap, which engages in one of several bores cut out in the web of the buckle lever. However, this would complicate the manufacture of the strap buckle. To simplify production, the invention therefore provides according to claim 2 that the Flap is held in each locked position by at least one locking lug arranged on the top of the buckle lever at least in the direction of the pull of the rope.

Der Gegenstand des Anspruches 3 bezieht sich auf eine zweite Ausführungsform der Erfindung, die in ihrem ersten Teil gleichfalls von einer Bügelschnalle gemäß dem DE-U-1 910 435 ausgeht, nämlich von einer Bügelschnalle zum Verschließen von Skischuhen, mit einer mit dem Skischuh fest verbundenen Grundplatte, an der ein im Querschnitt U-förmiger Schnallenhebel mit seiner Achse schwenkbar gelagert ist, der zwischen einer Offen- und einer Schließlage verschwenkbar ist und der mit einem Zylinder verbunden ist, dessen Achse parallel zur Hebelachse verläuft und in dessen mit einem Gewinde versehener Querbohrung eine Schraube bzw. eine Gewindehülse, welche mit einem den Skischuh verschließenden Element verbunden ist, gelagert ist, wobei der Zylinder in Längsrichtung des Schnallenhebels in zwei Relativlagen einstellbar ist.The subject matter of claim 3 relates to a second embodiment of the invention, which in its first part also starts from a strap buckle according to DE-U-1 910 435, namely from a strap buckle for closing ski boots, with one firmly connected to the ski boot Base plate on which a cross-sectionally U-shaped buckle lever is pivotally mounted with its axis, which is pivotable between an open and a closed position and which is connected to a cylinder, the axis of which runs parallel to the lever axis and in its threaded cross bore a screw or a threaded sleeve, which is connected to an element closing the ski boot, is mounted, the cylinder being adjustable in two relative positions in the longitudinal direction of the buckle lever.

Diese Ausführungsform zeichnet sich erfindungsgemäß dadurch aus, daß an den Innenseiten der Schenkel des Schnallenhebels auf Achsstummeln zwei Gelenklaschen gelagert sind, und daß die Schraube bzw. die Gewindehülse unmittelbar fest mit einem den Skischuh verschließenden Seil verbunden ist. Diese Konstruktion ermöglicht eine Grobverstellung der wirksamen Seillänge zwar nur in zwei Lagen, sie hat gegenüber der ersten Ausführungsform jedoch den Vorteil, daß die Oberseite des Schnallenhebels durchgehend glatt ausgeführt ist und daß sich der Skiläufer bei einem Sturz nicht an vorspringenden Teilen verletzen kann.This embodiment is characterized in that two articulated brackets are mounted on stub axles on the inner sides of the legs of the buckle lever, and that the screw or the threaded sleeve is directly and firmly connected to a rope closing the ski boot. This construction allows a rough adjustment of the effective rope length only in two layers, but it has the advantage over the first embodiment that the top of the buckle lever is continuously smooth and that the skier cannot be injured by protruding parts in the event of a fall.

Im übrigen sind bei beiden Ausführungsformen die wesentlichen Teile im U-förmigen Schnallenhebel untergebracht und daher gegen Schnee und Verunreinigungen geschützt.Incidentally, in both embodiments, the essential parts are housed in the U-shaped buckle lever and therefore protected against snow and dirt.

In der Zeichnung sind zwei beispielsweise Ausführungsformen der Erfindung wiedergegeben. Fig. 1 ist eine Seitenansicht der ersten Ausführungsform in der geschlossenen Stellung bei äußerer Lage des Seilendes und Fig. 2 eine dazugehörige Draufsicht. Fig. 3 zeigt einen Schnitt nach der Linie III - III in Fig. 2 und Fig. 4 einen Schnitt nach der Linie IV - IV in Fig. 2. Fig. 5 ist eine Seitenansicht der Bügelschnalle mit aufgeklapptem Schnallenhebel. Fig. 6 ist ein vertikaler Längsmittelschnitt durch eine zweite Ausführungsform in der inneren Lage und in geschlossener Stellung und Fig. 7 der gleiche Schnitt mit aufgeklapptem Schnallenhebel während des Verstellvorganges in die äußere Lage des Seilendes.Two exemplary embodiments of the invention are shown in the drawing. Fig. 1 is a side view of the first embodiment in the closed Position in the outer position of the rope end and Fig. 2 is an associated plan view. Fig. 3 shows a section along the line III - III in Fig. 2 and Fig. 4 shows a section along the line IV - IV in Fig. 2. Fig. 5 is a side view of the bow buckle with the buckle lever open. Fig. 6 is a vertical longitudinal central section through a second embodiment in the inner position and in the closed position and Fig. 7 is the same section with the buckle lever open during the adjustment process in the outer position of the rope end.

Die in den Fig. 1 bis 5 dargestellte Bügelschnalle weist eine im Querschnitt U-förmige Grundplatte 1 auf, deren Steg 1a mit der Schale 2 eines Skischuhs beispielsweise durch Nieten 3 fest verbunden ist. In den beiden Schenkeln 1b der Grundplatte 1 ist auf einer von zwei quer verlaufenden Halbachsen 4 gebildeten Achse ein Schnallenhebel 5 schwenkbar gelagert, der gleichfalls über einen U-förmigen Querschnitt verfügt. Der Steg 5a des Schnallenhebels 5 besitzt einen Längsschlitz 5c, der im Bereich der Halbachsen 4 offen ist. In den beiden Schenkeln 5b des Schnallenhebels 5 sind Langlöcher 5d ausgespart, die in Längsrichtung des Schnallenhebels 5 verlaufen. In diesen Langlöchern 5d wird die Achse 6 eines Zylinders 7 geführt. Letzterer wird von einer Bohrung bzw. von einer Gewindebohrung 7a, welche quer zur Achse 6 bzw. zum Zylinder 7 verläuft, durchsetzt. In diese Gewindebohrung 7a ist eine Schraube 8 mit einem gerändelten Kopf 8a eingeschraubt, welche mit einem Seil 9 fest verbunden ist.1 to 5 has a cross-sectionally U-shaped base plate 1, the web 1a of which is firmly connected to the shell 2 of a ski boot, for example by rivets 3. In the two legs 1b of the base plate 1, a buckle lever 5 is pivotally mounted on an axis formed by two transverse semiaxes 4, which also has a U-shaped cross section. The web 5a of the buckle lever 5 has a longitudinal slot 5c which is open in the region of the semiaxes 4. Elongated holes 5d are left in the two legs 5b of the buckle lever 5 and run in the longitudinal direction of the buckle lever 5. The axis 6 of a cylinder 7 is guided in these elongated holes 5d. The latter is penetrated by a bore or by a threaded bore 7a, which runs transversely to the axis 6 or to the cylinder 7. In this threaded hole 7a, a screw 8 is screwed with a knurled head 8a, which is fixedly connected to a rope 9.

Es ist jedoch auch möglich, anstelle der Schraube eine Hülse in der Querbohrung des Zylinders drehbar,aber gegen axiales Verschieben gesichert zu lagern, welche Hülse an dem herausragenden Ende mit einer Rändelung versehen ist und an ihrer Innenseite ein Gewinde trägt. In dieses Gewinde ist eine gegebenenfalls axial durchbohrte Madenschraube eingeschraubt, welche mit dem Seil durch Hartlöten oder Schweißen fest verbunden ist. Durch Verdrehen der Hülse wird eine Feineinstellung der wirksamen Seillänge herbeigeführt. Zur Führung des Seiles 9 weist der Steg 1a in der Grundplatte an seinem den Schenkein 1b benachbarten Ende eine schräg verlaufende Bohrung 1c auf, die sich in einer Bohrung 2a der Schale 2 fortsetzt.However, it is also possible, instead of the screw, to rotatably support a sleeve in the transverse bore of the cylinder, but secured against axial displacement, which sleeve is provided with knurling at the projecting end and has a thread on the inside. In this thread, an axially pierced grub screw is screwed, which is firmly connected to the rope by brazing or welding. By twisting the sleeve, the effective rope length is fine-tuned. To guide the cable 9, the web 1a has in the base plate at its end adjacent to the leg 1b an obliquely extending bore 1c which continues in a bore 2a of the shell 2.

Die Achse 6 des Zylinders 7 ist über die beiden Schenkel 5b des Schnallenhebels 5 hinaus verlängert und greift in die Schenkel 10a einer im Querschnitt U-förmigen Klappe 10 ein. Der Steg 10b der Klappe 10 ist mit zwei Ausnehmungen 10c versehen, die zum Verrasten der Klappe 10 in einer von zwei oder mehr Lagen bestimmt sind. Zu diesem Zweck trägt der Steg 5a des Schnallenhebels 5 zu beiden Seiten der vertikalen Längssymmetrieebene als Rastnasen ausgebildete Ausprägungen 5e, an denen das eine Ende des Steges 10b der Klappe 10 oder der eine Rand der beiden Ausnehmungen 10c anliegt. In der geschlossenen Lage liegt der Steg 10b der Klappe 10 auf dem Steg 5a des Schnallenhebels 5 auf und wird vom gespannten Seil 9 festgehalten (s. Fig. 1 und 3).The axis 6 of the cylinder 7 is extended beyond the two legs 5b of the buckle lever 5 and engages in the legs 10a of a flap 10 which is U-shaped in cross section. The web 10b of the flap 10 is provided with two recesses 10c, which are intended for locking the flap 10 in one of two or more layers. For this purpose, the web 5a of the buckle lever 5 carries on both sides of the vertical plane of longitudinal symmetry formed as detents 5e, against which one end of the web 10b of the flap 10 or one edge of the two recesses 10c abuts. In the closed position, the web 10b of the flap 10 rests on the web 5a of the buckle lever 5 and is held in place by the tensioned cable 9 (see FIGS. 1 and 3).

Soll die Bügelschnalle geöffnet werden, so wird der Schnallenhebel 5 aus der in den Fig.1 und 3 dargestellten Lage entgegen dem Uhrzeigersinn um die Halbachsen 4 nach oben verschwenkt. Dabei wird das Seil 9 etwas entspannt. Ist eine Änderung der wirksamen Länge des Seiles 9 erforderlich, so wird zur Grobverstellung zunächst auch die Klappe 10 entgegen dem Uhrzeigersinn verschwenkt, wodurch die Achse 6 freigegeben wird (s. Fig. 5). Eine Verschiebung der Achse 6 des Zylinders 7 in den Langlöchern 5d des Schnallenhebels 5 ist nunmehr möglich. Dabei kann die Klappe 10 aus der mit vollen Linien wiedergegebenen Stellung in die strichpunktiert gezeichnete Lage 10′ verstellt werden. Danach wird die Klappe 10 im Uhrzeigersinn zurückgeschwenkt. Dabei rasten zwei der vier Ausprägungen 5e des Schnallenhebels 5 in den beiden Ausnehmungen 10c der Klappe 10 ein, und der Vorgang der Grobverstellung des Seiles 9 ist beendet.If the bow buckle is to be opened, the buckle lever 5 is pivoted counterclockwise from the position shown in FIGS. 1 and 3 around the semiaxes 4 upwards. The rope 9 is relaxed somewhat. If a change in the effective length of the cable 9 is required, the flap 10 is first pivoted counterclockwise for the rough adjustment, whereby the axis 6 is released (see FIG. 5). A displacement of the axis 6 of the cylinder 7 in the elongated holes 5d of the buckle lever 5 is now possible. The flap 10 can be adjusted from the position shown with full lines in the dash-dotted position 10 '. The flap 10 is then pivoted back in a clockwise direction. Two of the four forms 5e of the buckle lever 5 engage in the two recesses 10c of the flap 10, and the rough adjustment of the cable 9 is ended.

Soll das Seilende 9 auch fein eingestellt werden, so wird die Schraube 8, die über einen gerändelten Kopf 8a verfügt, mit der Hand solange verdreht, bis die gewünschte wirksame Länge des Seiles 9 erreicht ist.Danach wird der Schnallenhebel 5 im Uhrzeigersinn in die Stellung nach Fig. 1 bzw. 3 verschwenkt.If the rope end 9 is also to be finely adjusted, the screw 8, which has a knurled head 8a, is turned by hand until the desired effective length of the rope 9 is reached. The buckle lever 5 is then turned clockwise into the position 1 or 3 pivoted.

Die in den Fig. 6 und 7 dargestellte zweite Ausführungsform einer Bügelschnalle ist der zuerst beschriebenen Ausführungsform ähnlich. Auch sie besitzt eine im Querschnitt U-förmige Grundplatte 1′, deren Steg 1′a mit der nicht dargestellten Schale eines Skischuhs durch Nieten fest verbunden ist. In den beiden Schenkeln 1′b der Grundplatte 1′ sind auf quer verlaufenden Halbachsen 4′ die beiden Schenkel 5′b eines Schnallenhebels 5′ mit einem U-förmigen Querschnitt gelagert. Der Steg 5′a des Schnallenhebels 5′ verfügt über einen Längsschlitz 5′c, dessen den Halbachsen 4′ benachbartes Ende offen ist. Diesem Ende ist eine schräg verlaufende Bohrung 1′c im Steg 1′a der Grundplatte 1′ zugeordnet, die sich gegebenenfalls in eine Bohrung der Schale fortsetzt.The second embodiment of a strap buckle shown in FIGS. 6 and 7 is similar to the embodiment described first. It also has a cross-sectionally U-shaped base plate 1 ', the web 1'a of which is firmly connected to the shell of a ski boot, not shown, by rivets. In the two legs 1'b of the base plate 1 'are on transverse semiaxes 4', the two legs 5'b of a buckle lever 5 'with a U-shaped cross section. The web 5'a of the buckle lever 5 'has a longitudinal slot 5'c, the semiaxis 4' adjacent end is open. This end is an oblique bore 1'c in the web 1'a of the base plate 1 'assigned, which may continue into a hole in the shell.

Im Gegensatz zum ersten Ausführungsbeispiel ist bei der zweiten Ausführungsform die Achse 6′ des Zylinders 7′ nicht unmittelbar in den beiden Schenkeln 5′b des Schnallenhebels 5′ gelagert. Vielmehr sind an den Innenseiten der Schenkel 5′b zwei Gelenklaschen 20 mittels Achsstummeln 21 schwenkbar gelagert, welche an ihren freien Enden die Achse 6′ des Zylinders 7′ tragen. Dieser Zylinder 7′ ist, wie dies auch beim ersten Ausführungsbeispiel der Fall ist, mit einer quer zur Achse 6′ bzw. zum Zylinder 7′ verlaufenden Gewindebohrung 7′a versehen, in die eine Schraube 8′ eingeschraubt ist, welche mit einem Seil 9′ fest verbunden ist.In contrast to the first embodiment, in the second embodiment, the axis 6 'of the cylinder 7' is not directly supported in the two legs 5'b of the buckle lever 5 '. Rather, there are two hinge straps 20 on the inside of the legs 5'b by means of stub axles 21 pivotally mounted, which carry the axis 6 'of the cylinder 7' at their free ends. This cylinder 7 'is, as is the case with the first embodiment, provided with a transverse to the axis 6' or the cylinder 7 'threaded bore 7'a, into which a screw 8' is screwed, which with a rope 9th 'Is firmly connected.

In der verriegelten Stellung nehmen alle Teile der Bügelschnalle die in Fig. 6 dargestellte Lage ein. Soll nun die wirksame Länge des Seiles 9′ verändert werden, so wird der Schnallenhebel 5′ entgegen dem Uhrzeigersinn um die Halbachsen 4′ verschwenkt. Soll die wirksame Seillänge vergrößert werden, so werden zur Grobeinstellung die beiden Gelenklaschen 20 um ihre Achsstummeln 21 um 180o verschwenkt (s. Fig.7). Dadurch wird die wirksame Seillänge um den doppelten Abstand der beiden Lagerbohrungen in den Gelenklaschen 20 vergrößert. Im Anschluß daran kann die Seillänge mittels der Schraube 8′ noch feineingestellt werden.In the locked position, all parts of the strap buckle assume the position shown in FIG. 6. If the effective length of the rope 9 'is now to be changed, the buckle lever 5' is pivoted counterclockwise around the semiaxes 4 '. If the effective cable length to be increased, the two joint plates 20 about its stub axles 21 to 180 o pivoted (s. Fig.7) are used for coarse adjustment. As a result, the effective rope length is increased by twice the distance between the two bearing bores in the link plates 20. Following this, the rope length can still be finely adjusted by means of the screw 8 '.

Sobald dieser Vorgang beendet ist, wird der Schnallenhebel 5′ um die Halbachsen 4′ im Uhrzeigersinn verschwenkt, bis er mit seinen Schenkeln 5′b am Steg 1′a der Grundplatte 1′ aufliegt. Durch die Spannung des Seiles 9′, das unterhalb der Halbachsen 4′ verläuft, ist der Schnallenhebel 5′ gegen ein unbeabsichtigtes Öffnen gesichert. Gleichzeitig ist auch der Rändelkopf 8′a der Schraube 8′ nach außen abgedeckt, so daß es zu keiner unbeabsichtigten Verdrehung der Schraube 8′ kommen kann.As soon as this process is complete, the buckle lever 5 'is pivoted clockwise around the semiaxes 4' until it rests with its legs 5'b on the web 1'a of the base plate 1 '. By the tension of the rope 9 ', which runs below the semiaxes 4', the buckle lever 5 'is secured against unintentional opening. At the same time, the knurled head 8'a of the screw 8 'is covered to the outside, so that there can be no unintentional rotation of the screw 8'.

Die Erfindung ist nicht an die in der Zeichnung dargestellten und im vorstehenden beschriebenen Ausführungsbeispiele gebunden. Vielmehr sind verschiedene Abänderungen derselben möglich, ohne den Rahmen der Erfindung zu verlassen. Beispielsweise sollen auch Ausführungsformen, bei denen der Schnallenhebel in der Normallage durch Rastvorsprünge, die in Ausnehmungen der Schenkel der Grundplatte eingreifen, gegenüber dieser festgehalten ist, unter den Schutz der Erfindung fallen.The invention is not tied to the exemplary embodiments shown in the drawing and described above. Rather, various modifications thereof are possible without the scope of the invention to leave. For example, embodiments in which the buckle lever is held in the normal position by means of latching projections which engage in recesses in the legs of the base plate are also to be protected by the invention.
