Description

Die Erfindung betrifft eine zusammenklappbare Anlegeleiter für Aufzugschachtgruben gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a folding ladder for hoistway pits according to the preamble of claim 1.

Eine in der US 2002/0112920 A1 anhand der Figuren 1A bis 3A beschriebene erste Ausführungsform einer zusammenklappbaren Anlegeleiter enthält

  • zwei Seitenholme (23, 25) in Form von U-Profilen gleicher Abmessungen mit nach innen, d.h. aufeinander zu gerichteten U-Profilschenkeln und
  • Stufen (27), die mit ihren Enden drehgelenkartig an den Seitenholmen (23, 25) angelenkt sind.
One in the US 2002/0112920 A1 based on FIGS. 1A to 3A described first embodiment of a collapsible laying ladder contains
  • two side rails (23, 25) in the form of U-profiles of the same dimensions with inwardly, ie towards each other directed U-profile legs and
  • Steps (27), the ends of which are pivotally articulated to the side rails (23, 25).

Eine in der US 2002/0112920 A1 anhand der Figuren 5A bis 7A beschriebene zweite Ausführungsform einer zusammenklappbaren Anlegeleiter enthält

  • zwei Seitenholme (23, 25) in Form von U-Profilen gleicher Abmessungen mit nach innen, d.h. aufeinander zu gerichteten U-Profilschenkeln und
  • einteilige Stufen (27) in Form von U-Profilen, deren U-Profilschenkel unter einem gleichen Winkel gegenüber der U-Profil-Basisfläche schräg gestellt sind, wobei
  • die Enden der Stufen (27) Achszapfen (107 bzw. 111 bzw. 115 bzw. 119) tragen, die in in den U-Profilschenkeln der Seitenholme (23 und 25) angebrachten Langlöchern (113 bzw. 123) verschiebbar gelagert sind, derart, dass die Stufen relativ zu den Seitenholmen verschwenkbar sind.
One in the US 2002/0112920 A1 based on FIGS. 5A to 7A described second embodiment of a collapsible laying ladder contains
  • two side rails (23, 25) in the form of U-profiles of the same dimensions with inwardly, ie towards each other directed U-profile legs and
  • one-piece steps (27) in the form of U-profiles whose U-profile legs are inclined at an equal angle to the U-shaped base surface, wherein
  • the ends of the steps (27) bear stub axles (107, 111, 115, 119) which are slidably mounted in slots (113, 123, respectively) in the U-profile legs of the side rails (23, 25), that the steps are pivotable relative to the side rails.

Bei einer in der EP 1 749 966 A2 beschriebenen Anlegeleiter mit zwei gleich groß dimensionierten Seitenholmen in Form von U-Profilen und einteiligen Stufen in Form von U-Profilen liegen die beiden Seitenholme im zusammengeklappten Zustand der Leiter gegeneinander an. Nachteilig bei dieser bekannten Leiter ist es, dass bei auseinander geklappter Leiter, d.h. im Benutzungszustand, die die Trittflächen der Stufen bildenden U-Profilsstege selbst bei gerundeter Oberseite schräg liegende Stufentrittflächen bilden, wodurch die Standsicherheit einer auf der Leiter stehenden Person beeinträchtigt wird, was insbesondere dann zu Risiken führen kann, wenn die die Leiter benutzende Person für längere Zeit auf der Leiter steht.At one in the EP 1 749 966 A2 described laying ladder with two equal-sized side rails in the form of U-profiles and one-piece steps in the form of U-profiles are the two side rails in the folded state of the ladder against each other. A disadvantage of this known ladder is that when unfolded ladder, ie in the state of use, form the treads of the steps forming U-profile webs even with rounded top oblique step tread surfaces, whereby the stability of a person standing on the ladder is impaired, which in particular can lead to risks if the person using the ladder is standing on the ladder for a longer period of time.

Bei einer in der JPS594000 U beschriebenen Anlegeleiter sind einteilige, stangen- bzw. stabförmig ausgebildeten Stufen (2) mit dem einen Ende drehgelenkartig um Achszapfen schwenkbar an dem ersten Seitenholm (1) angelenkt, während die gegenüberliegenden Stufenenden mittels Zapfen (3) entlang von in dem zweiten Seitenholm (1') angebrachten Langlöchern (4) verschiebbar und relativ zu dem Seitenholm (1') verschwenkbar sind. Die beiden Seitenholme (1, 1') haben die Form von U-Profilen, wobei die U-Schenkel des U-Profils des zweiten Seitenholms (1') eine geringere Höhe haben als die U-Schenkel des U-Profils des ersten Seitenholms (1). Dieser zweite Seitenholm (1') kann begrenzt durch die Achszapfen des ersten Seitenholms (1) in diesen eingeschoben werden, wozu das den zweiten Seitenholm (1') bildende U-Profil eine geringere Stegbreite hat als das den ersten Seitenholm (1) bildende U-Profil. Das Konstruktionsprinzip dieser bekannten Stufenleiter ist nicht für zusammenklappbare Stufen-Anlegeleitern geeignet, deren Stufen im wesentlichen die Form von U-Profilen haben, wobei beide Stufenenden an den Seitenholmen drehgelenkartig angelenkt sind.In a laying ladder described in JPS594000 U are one-piece, rod or rod-shaped steps (2) pivotally connected to one end pivoted about axle pivot on the first side spar (1), while the opposite step ends by means of pins (3) along in the second side spar (1 ') mounted slots (4) are displaceable and relative to the side spar (1') are pivotable. The two side rails (1, 1 ') have the shape of U-profiles, wherein the U-legs of the U-profile of the second side member (1') have a lower height than the U-legs of the U-profile of the first side member ( 1). This second side spar (1 ') can be limited by the axle journal of the first side spar (1) inserted into this, including the second side spar (1') forming U-profile has a smaller web width than the first side spar (1) forming U -Profile. The design principle of this known graduated ladder is not suitable for collapsible step-ladders whose stages have substantially the shape of U-profiles, both stage ends are hinged to the side rails pivot.

In der EP 0 160 600 ist eine Anlegeleiter mit Seitenholmen in Form von gleich groß gestalteten U-Profilen beschrieben, an denen die Enden von im Wesentlichen mittig geteilten zweiteiligen Stufen angelenkt sind, die die Form von U-Profilen haben, deren Schenkel gegenüber der Basisfläche des U-Profils eine schräge Anordnung haben, um im Gebrauchszustand der Leiter für den Benutzer eine verbesserte Stabilität zu erreichen, indem die an die vordere Stufenseite angrenzenden Schenkel der Stufen eine geringere Höhe haben als die an die hintere Stufenseite angrenzender Schenkel der Stufen.In the EP 0 160 600 a ladder is described with side rails in the form of U-profiles of equal size, in which the ends of substantially centrally divided two-part steps are hinged, which have the shape of U-profiles, whose legs relative to the base surface of the U-profile an oblique Have arrangement to in the Use state of the ladder for the user to achieve improved stability by the leg of the steps adjacent to the front step side have a lower height than the leg of the steps adjacent to the rear step side.

Im Gegensatz dazu ist die erfindungsgemäße Stufen-Anlegeleiter durch die Merkmale des Kennzeichnens Anspruchs 1 gekennzeichnet. - Indem die U-Profilschenkel des einen Seitenholms gegenüber den U-Profilschenkeln des anderen Seitenholms verkürzt sind, wird der Raumbedarf für die zusammengeklappte Leiter verringert. Dabei ist zu berücksichtigen, dass in Aufzugsschachtgruben nur ein sehr geringer Speicherraum zur Verfügung steht, so dass selbst eine geringfügige Verringerung des Platzbedarfes für die zusammengeklappte Leiter vorteilhaft sind.

  • Durch die Schrägstellung der U-Profilschenkel gegenüber der U-Profil-Basisfläche wird erreicht, dass im Benutzungszustand der Leiter die die Stufentrittfläche bildenden U-Profil-Basisflächen bei einer entsprechenden Schrägstellung der Leiter eine im Wesentlichen horizontale Lage einnehmen. Die Schrägstellung der U-Profilschenkel der Stufen gegenüber der U-Profil-Basisfläche beträgt bei einem unterstellten Anstellwinkel der Leiter gegen eine Wandfläche etwa 70°.
  • Indem die U-Profile der Stufen angrenzend an die Stufenenden mit Aussparungen versehen sind, wird bei zusammengeklappter, d.h. ineinandergeschobenen Stellung der Seitenholme eine gegenseitige Beeinträchtigung der Stufenenden mit den Seitenholmen vermieden, wobei zusätzlich beim Ausklappen der Leiter Fingerquetschungen verhindert werden.
In contrast, the step ladder according to the invention is characterized by the features of characterizing claim 1. - By the U-profile legs of a side spar are shortened compared to the U-profile legs of the other side spar, the space required for the collapsed ladder is reduced. It should be noted that in elevator shaft pits only a very small storage space is available, so that even a slight reduction in space requirements for the folded ladder are advantageous.
  • Due to the inclination of the U-profile legs relative to the U-profile base surface is achieved that in the state of use of the ladder the step tread surface forming U-shaped base surfaces occupy a substantially horizontal position at a corresponding inclination of the ladder. The inclination of the U-profile legs of the steps relative to the U-shaped base surface is at an assumed angle of attack of the head against a wall surface about 70 °.
  • By the U-profiles of the steps are provided adjacent the step ends with recesses, a mutual impairment of the step ends is avoided with the side rails in collapsed, ie nested position of the side rails, and in addition finger folds are prevented when unfolding the ladder.

Die in den Figuren 1 bis 3 dargestellte Leiter hat zwei Seitenholme 1, 2 in Form von U-Profilen. An den beiden Seitenholmen 1, 2 sind Stufen 3 derart angelenkt, dass die Seitenholme 1, 2 durch Verschwenken um die Schwenkachsen zwischen den Stufen und den Seitenholmen relativ zueinander aufeinander zu bzw. voneinander weg verstellbar, d.h. zusammenklappbar bzw. auseinanderklappbar sind.

Die Stufen 3 haben gemäß Figur 9 die Form von U-Profilen mit gegenüber der U-Profil-Basisfläche 3.1 unter dem Winkel β parallel zueinander schräg gestellten U-Profilschenkeln 3.2, bzw. 3.3. Der Winkel β hat entsprechend einem z.B. vorgesehenen Anlegewinkel γ der Leiter gegen eine Stützfläche - siehe Figur 11 - im Bereich von etwa 70° einen entsprechenden Wert von ebenfalls 70°, um bei in dem Schacht aufgestellter Leiter eine nahezu horizontale Trittfläche zu erhalten; die die Stufentiefe bestimmende Breite a 1 der U-Profil-Basisfläche 3.1 liegt in der Größenordnung von etwa 80 mm; die Höhe c 1 des U-Profilschenkels 3.2 beträgt beispielsweise etwa 18 mm und die Höhe b 1 des U-Profilschenkels 3.3 beträgt beispielsweise etwa 44 mm. Es versteht sich, dass diese Abmessungen nur als Beispiele gelten und in Abhängigkeit von den jeweiligen Anforderungen und den zu beachtenden Normen von den angegebenen Werten abweichen können.The levels 3 are according to FIG. 9 the shape of U-profiles with respect to the U-shaped base surface 3.1 at an angle β parallel to each other obliquely U-profile legs 3.2, and 3.3. The angle β has, for example, an angle of inclination γ of the conductors against a support surface - see FIG. 11 - In the range of about 70 ° a corresponding value of 70 °, in order to get established in the shaft ladder a nearly horizontal tread surface; the step depth determining width a 1 of the U-shaped base surface 3.1 is in the order of about 80 mm; the height c 1 of the U-profile leg 3.2 is for example about 18 mm and the height b 1 of the U-profile leg 3.3 is for example about 44 mm. It goes without saying that these dimensions are only examples and may deviate from the stated values depending on the respective requirements and the standards to be observed.

Die Abmessungen der die Seitenholme 1, 2 bildenden U-Profile sind auf die Abmessungen der Stufen 3 abgestimmt, derart, dass die Stufen 3 unter Berücksichtigung ihrer Abmessungen und der Position der Anlenkpunkte an den Seitenholmen insbesondere in den Seitenholm 2 mit den gegenüber den U-Profilschenkeln 1.1 des Seitenholms 1 höheren U-Profilschenkeln 2.1 einklappbar sind. Als Anlenkpunkte im Bereich der Seitenholme 1, 2 dienen Bohrungen 6 in den U-Profilschenkeln der beiden Seitenholme 1, 2.The dimensions of the U-profiles forming the side rails 1, 2 are matched to the dimensions of the steps 3, such that the steps 3, taking into account their dimensions and the position of the articulation points on the side rails, in particular in the side rail 2 with respect to the U Profile legs 1.1 of the side member 1 higher U-profile legs 2.1 are collapsible. As articulation points in the area of the side rails 1, 2 holes 6 in the U-profile legs of the two side rails 1, 2 are used.

Die U-Profilschenkel 3.2 und 3.3 sind mit Anlenkpunkte 5 bildenden Bohrungen (Durchmesser z.B. 8 mm) versehen, die im Bereich der an die vordere Stufenseite angrenzenden U-Profilschenkel 3.2 einen kleineren Abstand von der die Stufentrittfläche bildenden U-Profil-Basisfläche 3.1 haben als die Anlenkpunkte 5 im Bereich der an die hintere Stufenseite angrenzenden U-Profilschenkel 3.3, um in Abhängigkeit von der Schrägstellung der U-Profilschenkel 3.2; 3.3 gegenüber der Basisfläche 3.1 das Auseinanderklappen bzw. Zusammenklappen der Leiter zu ermöglichen.The U-profile legs 3.2 and 3.3 are provided with articulation points 5 forming holes (diameter eg 8 mm), which in the area adjacent to the front step side U-profile leg 3.2 a smaller distance from the step tread surface forming U-shaped base surface 3.1 as the pivot points 5 in the region of the adjoining the rear step side U-profile leg 3.3, in response to the inclination of the U-profile legs 3.2; 3.3 with respect to the base surface 3.1 to allow the unfolding or folding of the ladder.

Zum Anlenken der Stufen 3 an den Seitenholmen 1, 2 können entweder relativ kurze Gelenkbolzen 7 oder eine durchgehende Gelenkachse 7.1 vorgesehen sein.For the articulation of the steps 3 on the side rails 1, 2 either relatively short hinge pin 7 or a continuous hinge axis 7.1 may be provided.

Gemäß den Figuren 4 und 10 sind die Stufen 3 jeweils an den Enden der U-Profil-Basisfläche 3.1, sowie des U-Profilschenkels 3.3 mit zum Teil ineinander übergehenden Aussparungen 3.11; 3.12; 3.31; 3.32 versehen. In Abhängigkeit von den Abmessungen der die Seitenholme 1,2 und der die Stufen 3 bildenden U-Profile, dem angenommenen bzw. geforderten Leiter-Anlegewinkel und der durch die Bohrungen 5, 6 bestimmten örtlichen Lage der Gelenkbolzen 7 bzw. Gelenkachsen 7.1 besteht beim Zusammenklappen der Leiter das Problem, dass die Trittfläche einer Stufe in den Raum der nächsthöheren Stufe und in den Raum der Gelenkachse derselben hineinragt. Dieses Problem wird durch die Anordnung und Abmessung der einzelnen Aussparungen gelöst. Die Aussparung 3.11 in der U-Profil-Basisfläche 3.1 und die Aussparung 3.31 in dem U-Profilschenkel 3.3 haben bei ausreichender Dimensionierung eine zusätzliche, vorteilhafte Funktion als "Fingerschutzelemente".According to the FIGS. 4 and 10 the steps 3 are each at the ends of the U-shaped base surface 3.1, and the U-profile leg 3.3 with partially merging recesses 3.11; 3.12; 3.31; 3.32 provided. Depending on the dimensions of the side rails 1.2 and the U-profiles forming the steps 3, the assumed or required conductor contact angle and the local position of the hinge pins 7 or joint axes 7.1 determined by the bores 5, 6, folding the ladder has the problem that the tread of one step projects into the space of the next higher step and into the space of the hinge axis of the same. This problem is solved by the arrangement and dimension of the individual recesses. The recess 3.11 in the U-profile base surface 3.1 and the recess 3.31 in the U-profile leg 3.3 have an additional, advantageous function as "finger protection elements" with sufficient dimensioning.

Hinsichtlich der Anordnung und Größe der Aussparungen ist ein Kompromiss zu schließen unter Berücksichtigung dessen, dass die Aussparungen einerseits ausreichend groß sind, um die Leiter zusammenklappen zu können und auch eine Finger-Abschergefahr auszuschalten, und andererseits die Stabilität der Stufen nicht durch übermäßig große Aussparungen gefährdet bzw. beeinträchtigt wird.As regards the arrangement and size of the recesses, a compromise has to be made taking into account that the recesses are on the one hand sufficiently large to be able to fold the ladder and also to eliminate the danger of finger scraping, and on the other hand do not endanger the stability of the steps by excessively large recesses or impaired.

Gemäß einer Ausfuhmngsform haben die in dem die Stufen 3 bildenden U-Profil angebrachten Aussparungen beispielsweise folgende Abmessungen:
(1) An den U-Profilschenkel 3.3 angrenzende Aussparung 3.11 in der U-Profil-Basisfläche 3.1: Länge in Profillängsrichtung - a4 etwa 40 - 45 mm Tiefe senkrecht zur Profillängsrichtung - a5 etwa 30 - 32 mm
(2) Aussparung 3.12: Länge in Profillängssrichtung - b4 etwa 20 mm Tiefe senkrecht zur Profillängsrichtung - a2 + a3 etwa 50 mm mit eventueller Abschrägung im mittleren Bereich
(3) Aussparung 3.31 im Schenkel 3.3: Länge in Profillängsrichtung - b5 etwa 40 - 45 mm Tiefe ab Schenkelinnenseite senkrecht zur Profillängsrichtung - b6 etwa 25 mm
(4) Ausparung 3.32: Länge in Schenkellängsrichtung - b4 etwa 20 mm Tiefe senkrecht zur Schenkellängsrichtung - b2 etwa 12 mm. According to a Ausfuhmngsform the in the step 3 forming U-shaped recesses have, for example, the following dimensions:
(1) In the U-profile base surface 3.1 adjacent to the U-profile leg 3.3 3.11 Length in profile longitudinal direction - a 4 about 40 - 45 mm Depth perpendicular to the profile longitudinal direction - a 5 about 30 - 32 mm
