Definitions
- the present invention relates to a riser, z. B. a step ladder, a rung ladder or a Klapptritt with at least two spars, at least two rungs or steps, which are mounted between the spars, and at least two feet, which are each attached to a lower in the use position of the Steigraft one of the spars and depending have a first footprint over which rests the riser in the position of use on a floor.
- Such climbing devices e.g. Step ladders to set up, especially so-called household conductors are known from daily use many people.
- the spars of such risers are usually made of aluminum hollow sections.
- the feet are inserted in the bottom ends of the hollow sections and protect the floor from damage caused by the sharp-edged aluminum.
- the feet provide a level footprint of the ladder.
- the feet are usually made of a plastic material.
- the first footprint is usually profiled and relatively hard. When setting up the ladders on sensitive, especially soft substrates, this, the first footprint of the feet of the ladder can lead to damage to the substrate. For example, it may be possible for a profiled foot of a ladder to penetrate into a softer wooden floor, e.g. press in a parquet or board floor.
- the foot of such a climbing device is particularly advantageous in outdoor applications due to its profiled footprint.
- the invention is based on the object to improve a riser of the type mentioned so that on the one hand soft surfaces are protected from damage by the feet of the ladder and on the other hand, the feet of the ladder can be used in use on hard and rough surfaces.
- each foot has a removable element which can be brought from a rest position to a position of use in front of the first footprint to be arranged in the position of use of the Steigêts between the first footprint and the ground and in the use position a to form the second contact patch of the climbing device, which is an alternative to the first contact patch.
- a climbing device according to the invention can therefore be changed between two contact surfaces.
- a first footprint can be used, possibly having the usual characteristics of the known feet of ladders.
- a second footprint may be used, which may be formed of another material, and thus is particularly suitable for protecting soft surfaces, for example of wood, from being damaged by the conductors.
- the second footprint is provided to the change element of the foot.
- each foot may have a first part fixedly connected to the associated spar.
- Each foot may have a hinge or other connecting element, via which the changing element of the foot is pivotally connected about a pivot axis with the first part of the foot.
- the hinge can do it to be a film hinge.
- the pivot axis of the hinge is preferably arranged parallel to a rung or step of the climbing device. This arrangement of the pivot axis is of particular advantage, since then the interchangeable element protrudes in the rest position neither in an area between the spars or an area laterally of the spars. A protrude into the area between the spars and in the area laterally of the spars is a disadvantage, since in these areas easily contact and thus damage or accidental release of the removable element can be done in the rest position by feet of a user of the ladder.
- the pivot axis of the hinge can be present as a concrete component, for example in the form of a short rod.
- the axis of rotation does not have to be a concrete component. It can also be defined by structures on the first part and / or on the second part.
- the climbing device may have locking elements, with which the interchangeable element in the rest position and / or in the position of use can be determined. Some of the locking elements or all locking elements may be attached to the first parts of the feet and / or the interchangeable elements. It is also conceivable that some of the locking elements or all locking elements are attached to the bars of the ladder.
- the interchangeable elements and / or the first parts of the feet may have cantilevered elements as locking elements.
- locking lugs can be provided on the cantilever elements.
- the locking lugs can be locked in the rest position or in the position of use of the interchangeable elements behind projections, in undercuts, in notches, in grooves or the like.
- the overhanging elements are advantageously arranged substantially parallel to planes which are perpendicular to the pivot axis.
- the feet of the ladder may be a plastic part of at least two components.
- the first part or at least the first contact surface may be formed by a component, while the interchangeable element or at least the second contact surface may be formed by a second component.
- the first footprints of the feet may be rougher than the second footprints. It is also possible that the second contact surfaces are softer than the first contact surfaces. But it is also possible that the second footprint rougher and / or the first footprint is softer.
- the interchangeable elements may also be softer and / or harder as a whole than the first parts of the feet.
- the first parts of the feet can be at least partially plugged into one of the spars. It is also possible that the first parts of the feet each form a cap and that the caps are attached to each one of the spars.
- a climbing device claimed for setting up in particular a climbing device of the aforementioned type.
- This further claimed riser device has a riser and a support member, wherein the riser and the support member each have two spars and a spar of the riser and a spar of the support member on a hinge are connected together.
- the hinge includes a hinge member attached to a first portion at the end of one of the two spars of the support member. With another section is the hinge part between the spar of the support member and the associated spar of the riser arranged to prevent direct abutment of the spar of the support member and the spar of the riser.
- Each hinge part can be connected via an axis pivotally connected to the riser.
- the further portion of each hinge part abuts against the outside of the spar of the support member.
- the first portion of each hinge part is preferably inserted in the associated spar of the riser.
- the axle advantageously penetrates the first section and the further section of the hinge part.
- the hinge part has holes for drilling.
- like reference numerals are used for parts of the various ladders, as far as these parts differ in their function.
- the different ladders differ only by the design of feet on the in the position of use of the ladders lower ends of bars 1.
- the ladders S point (see FIG. 1 ) a riser S1 and a support member S2, the usual as a step ladder pivotally mounted on a hinge with each other are connected.
- the riser S1 and the support member S2 have spars 1, which are connected by steps in the case of the riser S1.
- the feet 2 are provided.
- At the upper ends of the spars 1 of the support part hinge parts 3 are provided, which together with an axis 3a form the hinge of the ladder.

Abstract
Description
Die vorliegende Erfindung betrifft ein Steiggerät, z. B. eine Stufenleiter, eine Sprossenleiter oder einen Klapptritt mit wenigstens zwei Holmen, wenigstens zwei Sprossen oder Stufen, die zwischen den Holmen angebracht sind, und wenigstens zwei Füßen, die jeweils an einem in Gebrauchslage des Steiggeräts unteren Ende eines der Holme angebracht sind und je eine erste Aufstandsfläche aufweisen, über die das Steiggerät in der Gebrauchslage auf einem Boden ruht.The present invention relates to a riser, z. B. a step ladder, a rung ladder or a Klapptritt with at least two spars, at least two rungs or steps, which are mounted between the spars, and at least two feet, which are each attached to a lower in the use position of the Steigraft one of the spars and depending have a first footprint over which rests the riser in the position of use on a floor.
Derartige Steiggeräte, z.B. Stufenstehleitern zum Aufstellen, insbesondere sogenannte Haushaltsleitern sind aus dem täglichen Gebrauch vielen Personen bekannt. Die Holme solcher Steiggeräte sind in der Regel aus Aluminium-Hohlprofilen hergestellt. Die Füße sind in den bodenseitigen Enden der Hohlprofile eingesteckt und schützen den Boden vor Beschädigungen durch das scharfkantige Aluminium. Außerdem sorgen die Füße für eine ebene Aufstandsfläche der Leiter. Die Füße sind in der Regel aus einem Kunststoffmaterial hergestellt. Die erste Aufstandsfläche ist im Regelfall profiliert und relativ hart. Beim Aufstellen der Leitern auf empfindlichen, insbesondere weichen Untergründen kann diese, erste Aufstandsfläche der Füße der Leitern zu Beschädigungen an dem Untergrund führen. Es ist beispielsweise möglich, dass sich dadurch so ein profilierter Fuß einer Leiter in einen weicheren Holzfußboden, z.B. einen Parkett- oder Dielenboden eindrückt.Such climbing devices, e.g. Step ladders to set up, especially so-called household conductors are known from daily use many people. The spars of such risers are usually made of aluminum hollow sections. The feet are inserted in the bottom ends of the hollow sections and protect the floor from damage caused by the sharp-edged aluminum. In addition, the feet provide a level footprint of the ladder. The feet are usually made of a plastic material. The first footprint is usually profiled and relatively hard. When setting up the ladders on sensitive, especially soft substrates, this, the first footprint of the feet of the ladder can lead to damage to the substrate. For example, it may be possible for a profiled foot of a ladder to penetrate into a softer wooden floor, e.g. press in a parquet or board floor.
Andererseits ist der Fuß eines solchen Steiggeräts insbesondere bei Anwendungen im Außenbereich von Vorteil auf Grund seiner profilierten Aufstandsfläche.On the other hand, the foot of such a climbing device is particularly advantageous in outdoor applications due to its profiled footprint.
Hier setzt die vorliegende Erfindung an.This is where the present invention begins.
Der Erfindung liegt die Aufgabe zu Grunde, ein Steiggerät der eingangs genannten Art so zu verbessern, dass einerseits weiche Untergründe vor Beschädigungen durch die Füße der Leiter geschützt sind und andererseits die Füße der Leiter bei der Verwendung auf harten und rauen Untergründen verwendet werden können.The invention is based on the object to improve a riser of the type mentioned so that on the one hand soft surfaces are protected from damage by the feet of the ladder and on the other hand, the feet of the ladder can be used in use on hard and rough surfaces.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass jeder Fuß ein Wechselelement aufweist, das aus einer Ruhestellung in eine Gebrauchsstellung vor die erste Aufstandsfläche bringbar ist, um in der Gebrauchslage des Steiggeräts zwischen der ersten Aufstandsfläche und dem Boden angeordnet zu sein und um in der Gebrauchslage eine zweite Aufstandsfläche des Steiggeräts zu bilden, die eine Alternative zur ersten Aufstandsfläche ist. Bei einem erfindungsgemäßen Steiggerät kann also zwischen zwei Aufstandsflächen gewechselt werden. Zum einen kann eine erste Aufstandsfläche verwendet werden, die möglicherweise die üblichen Eigenschaften der bekannten Füße von Leitern hat. Anstelle dieser ersten Aufstandsfläche kann allerdings auch eine zweite Aufstandsfläche verwendet werden, die möglicherweise von einem anderen Material gebildet wird, und daher besonders geeignet ist, um weiche Untergründe, zum Beispiel aus Holz vor Beschädigungen durch die Leiter zu schützen. Die zweite Aufstandsfläche ist dazu an dem Wechselelement des Fußes vorgesehen.This object is achieved in that each foot has a removable element which can be brought from a rest position to a position of use in front of the first footprint to be arranged in the position of use of the Steiggeräts between the first footprint and the ground and in the use position a to form the second contact patch of the climbing device, which is an alternative to the first contact patch. In a climbing device according to the invention can therefore be changed between two contact surfaces. On the one hand, a first footprint can be used, possibly having the usual characteristics of the known feet of ladders. However, instead of this first footprint, a second footprint may be used, which may be formed of another material, and thus is particularly suitable for protecting soft surfaces, for example of wood, from being damaged by the conductors. The second footprint is provided to the change element of the foot.
Gemäß der Erfindung kann jeder Fuß ein erstes Teil aufweisen, das fest mit dem zugeordneten Holm verbunden ist. Jeder Fuß kann ein Scharnier oder anderes Verbindungselement aufweisen, über das das Wechselelement des Fußes um eine Schwenkachse schwenkbar mit dem ersten Teil des Fußes verbunden ist. Bei dem Scharnier kann es sich um ein Filmscharnier handeln. Die Schwenkachse des Scharniers ist vorzugsweise parallel zu einer Sprosse oder Stufe des Steiggeräts angeordnet. Diese Anordnung der Schwenkachse ist von besonderem Vorteil, da dann das Wechselelement in der Ruhestellung weder in einen Bereich zwischen den Holmen oder einen Bereich seitlich der Holme hineinragt. Ein Hineinragen in den Bereich zwischen den Holmen bzw. in den Bereich seitlich der Holme ist von Nachteil, da in diesen Bereichen leicht eine Berührung und damit auch eine Beschädigung oder ein Unbeabsichtigtes Lösen des Wechselelementes in der Ruhestellung durch Füße eines Benutzers der Leiter erfolgen kann.According to the invention, each foot may have a first part fixedly connected to the associated spar. Each foot may have a hinge or other connecting element, via which the changing element of the foot is pivotally connected about a pivot axis with the first part of the foot. The hinge can do it to be a film hinge. The pivot axis of the hinge is preferably arranged parallel to a rung or step of the climbing device. This arrangement of the pivot axis is of particular advantage, since then the interchangeable element protrudes in the rest position neither in an area between the spars or an area laterally of the spars. A protrude into the area between the spars and in the area laterally of the spars is a disadvantage, since in these areas easily contact and thus damage or accidental release of the removable element can be done in the rest position by feet of a user of the ladder.
Die Schwenkachse des Scharniers kann als konkretes Bauteil, beispielsweise in Form einer kurzen Stange vorliegen. Die Drehachse muss aber nicht als konkretes Bauteil vorliegen. Sie kann auch durch Strukturen am ersten Teil und/oder am zweiten Teil definiert sein.The pivot axis of the hinge can be present as a concrete component, for example in the form of a short rod. However, the axis of rotation does not have to be a concrete component. It can also be defined by structures on the first part and / or on the second part.
Das Steiggerät kann Feststellelemente aufweisen, mit welchen das Wechselelement in der Ruhestellung und/oder in der Gebrauchsstellung festgestellt werden kann. Einige der Feststellelemente oder alle Feststellelemente können an den ersten Teilen der Füße und/oder den Wechselelementen angebracht sein. Ebenso ist es denkbar, dass einige der Feststellelemente oder alle Feststellelemente an den Holmen der Leiter angebracht sind.The climbing device may have locking elements, with which the interchangeable element in the rest position and / or in the position of use can be determined. Some of the locking elements or all locking elements may be attached to the first parts of the feet and / or the interchangeable elements. It is also conceivable that some of the locking elements or all locking elements are attached to the bars of the ladder.
Die Wechselelemente und/oder die ersten Teile der Füße können als Feststellelemente auskragende Elemente aufweisen. An den auskragenden Elementen können Rastnasen vorgesehen sein. Die Rastnasen können in der Ruhestellung bzw. in der Gebrauchsstellung der Wechselelemente hinter Vorsprüngen, in Hinterschnitten, in Kerben, in Nuten oder dergleichen eingerastet sein. Die auskragenden Elemente sind vorteilhaft im Wesentlichen parallel zu Ebenen angeordnet, die senkrecht zur Schwenkachse liegen.The interchangeable elements and / or the first parts of the feet may have cantilevered elements as locking elements. On the cantilever elements locking lugs can be provided. The locking lugs can be locked in the rest position or in the position of use of the interchangeable elements behind projections, in undercuts, in notches, in grooves or the like. The overhanging elements are advantageously arranged substantially parallel to planes which are perpendicular to the pivot axis.
Die Füße der Leiter können ein Kunststoffteil aus wenigstens zwei Komponenten sein. Das erste Teil oder zumindest die erste Aufstandsfläche kann durch eine Komponente gebildet sein, während das Wechselelement oder zumindest die zweite Aufstandsfläche durch eine zweite Komponente gebildet sein kann.The feet of the ladder may be a plastic part of at least two components. The first part or at least the first contact surface may be formed by a component, while the interchangeable element or at least the second contact surface may be formed by a second component.
Die ersten Aufstandsflächen der Füße können rauer sein als die zweiten Aufstandsflächen. Ebenso ist es möglich, dass die zweiten Aufstandsflächen weicher sind als die ersten Aufstandsflächen. Es ist aber auch möglich, dass die zweite Aufstandsfläche rauer und/oder die erste Aufstandsfläche weicher ist.The first footprints of the feet may be rougher than the second footprints. It is also possible that the second contact surfaces are softer than the first contact surfaces. But it is also possible that the second footprint rougher and / or the first footprint is softer.
Die Wechselelemente können auch als ganzes weicher und/oder härter sein als die ersten Teile der Füße.The interchangeable elements may also be softer and / or harder as a whole than the first parts of the feet.
Die ersten Teile der Füße können zumindest zum Teil in einen der Holme eingesteckt sein. Ebenso ist es möglich, dass die ersten Teile der Füße jeweils eine Kappe bilden und dass die Kappen auf je einen der Holme aufgesteckt sind.The first parts of the feet can be at least partially plugged into one of the spars. It is also possible that the first parts of the feet each form a cap and that the caps are attached to each one of the spars.
Ferner wird ein Steiggerät zum Aufstellen beansprucht, insbesondere ein Steiggerät der vorgenannten Art. Dieses weitere beanspruchte Steiggerät weist ein Steigteil und ein Stützteil auf, wobei der Steigteil und der Stützteil jeweils zwei Holme aufweisen und je ein Holm des Steigteils und je ein Holm des Stützteils über ein Scharnier miteinander verbunden sind. Das Scharnier umfasst ein Scharnierteil, dass mit einem ersten Abschnitt an dem Ende eines der beiden Holme des Stützteils befestigt ist. Mit einem weiteren Abschnitt ist das Scharnierteil zwischen dem Holm des Stützteils und dem zugeordneten Holm des Steigteils angeordnet, um ein direktes Aneinanderliegen des Holmes des Stützteils und des Holmes des Steigteils zu verhindern.Furthermore, a climbing device claimed for setting up, in particular a climbing device of the aforementioned type. This further claimed riser device has a riser and a support member, wherein the riser and the support member each have two spars and a spar of the riser and a spar of the support member on a hinge are connected together. The hinge includes a hinge member attached to a first portion at the end of one of the two spars of the support member. With another section is the hinge part between the spar of the support member and the associated spar of the riser arranged to prevent direct abutment of the spar of the support member and the spar of the riser.
Jedes Scharnierteil kann über eine Achse schwenkbar mit dem Steigteil verbunden sein. Der weitere Abschnitt jedes Scharnierteils liegt an der Außenseite des Holmes des Stützteils an. Der erste Abschnitt jedes Scharnierteils ist vorzugsweise in den zugeordneten Holm des Steigteils eingesteckt. Die Achse durchdringt vorteilhaft den ersten Abschnitt und den weiteren Abschnitt des Scharnierteils. Das Scharnierteil weist dazu Bohrungen auf.Each hinge part can be connected via an axis pivotally connected to the riser. The further portion of each hinge part abuts against the outside of the spar of the support member. The first portion of each hinge part is preferably inserted in the associated spar of the riser. The axle advantageously penetrates the first section and the further section of the hinge part. The hinge part has holes for drilling.
