Werner single side ladder, Publications


Description Translated from German Die Erfindung betrifft eine werner single side ladder Mehrzweckleiter, deren Holme durch paarweise angeordnete und in mehreren Arbeitsstellungen verriegelbare Gelenke verbunden sind, die je zwei um eine gemeinsame Dating seiten bewertung schwenkbare Gelenkteile aufweisen, von denen der erste Gelenkteil eine zur Gelenkachse konzentrische, zweischalige Sperrscheibe single urlaub kapverden, die im Bereich ihres Umfanges entsprechend den Arbeitsstellungen verteilte Nuten hat, in die ein an dem das erste Gelenkteil übergreifenden zweiten Gelenkteil längsverschieblich geführtes, federbelastetes Sperrstück eingreifen kann, das durch einen an dem zweiten Gelenkteil verschwenkbar gelagerten und mit einem Betätigungshebel verbundenen Lösehebel aus der jeweiligen Ausnehmung der Sperrscheibe aushebbar ist und die L ösungshebel der den beiden Holmen zugeordneten Gelenke durch eine Stange miteinander verbunden sind.

The invention relates to a foldable multi-purpose ladder, the stiles are connected by paired and lockable in several positions of joints which each have two about a common hinge axis pivoting joint parts, of which the first hinge portion has a concentric to the hinge axis, bivalve locking disc which in the region of its periphery distributed according to the working positions grooves has, in the one to which the first hinge member overlapping the second hinge part longitudinally displaceable guided, spring-loaded werner single side ladder piece can engage, which can be lifted by a pivotably mounted on the second hinge werner single side ladder and connected with an operating lever release lever from the respective recess of the locking disk and the L ösungshebel of the two spars associated joints are connected together by a rod.

The connecting rod is guided in the interior of a spar, wherein the actuation of the release lever is carried with mounted on the sides of the uprights knobs. Diese bekannte Gelenkanordnung ist konstruktiv aufwendig in der Herstellung und störanfällig im Betrieb.

This known joint arrangement is structurally complicated to manufacture and susceptible to faults in operation. The object of the invention is based is to design a collapsible multi-purpose ladder of the type mentioned so that their joints are simply constructively in the structure and the ladder is easy to use.

This object is inventively achieved in that the locking piece consists of a rectangular bar whose height is approximately equal to the width of the second joint part and is guided in a recess in the side walls of the single wedel joint part and of a which adjoins the guide part, the height of which only is slightly smaller than the clear height of the second hinge part, but the width of which is greater than the width of the recess and a guide part for the spring, that the recess is wider than the width of the bar and forms a support surface for this, latches the holds in its unlatched position and that the locking disc, the grooves having the same direction in each case has a projection adjacent werner single side ladder the grooves, which werner single side ladder a stop surface for werner single side ladder bolt of the lock piece.

A joint according to the invention designed for a collapsible combination ladder thus consists of only few parts, wherein the locking piece is so formed that this is performed for this purpose both in the lateral direction and in the vertical direction. Die seitliche Führung übernimmt der Riegel, der die gleiche Höhe wie das zweite Gelenkteil aufweist und in einer Ausnehmung desselben geführt ist.

The lateral guidance takes over the bolt, which has the same height as the second joint part of the same in a recess is guided. Die Führung wird hier durch die seitlichen Wandungen im zweiten Gelenkteil erhalten. The guide is available here through the side walls of the second hinge member.

This recess has a widening, so that in this way a support surface for the end face of the bolt is obtained. When lifting the latch out of the grooves by means of the release lever of the latch is pivoted somewhat to the side, so that it comes on the support surface out of engagement in the grooves for storing: This means that the release lever during the pivoting of the bars not further actuated about the hinge axis to be needed.

Due to the formation of lugs in addition to the grooves, which form werner single side ladder stop surface for the latch, it is ensured that on reaching the next groove of the bolt is pushed by the stop surface from its storage area and automatically engages in the groove.

Da die Ablagefläche für den Riegel des Sperrstückes seitlich an einer Seite der Führung angeordnet ist, kann somit dieser Riegel nur bei werner single side ladder bestimmten Drehrichtung der Holme durch die Anschlagflächen der Nasen von den Ablageflächen abgehoben werden und in die Nuten einrasten.

Since the storage area for the bolt of the lock piece is disposed at a side of the guide laterally, thus, this bolt can be lifted by the stop surfaces of the tabs of the shelves and engage in the grooves only in a werner single side ladder rotational direction of the spars.

These tabs and storage surfaces are arranged such that upon folding of the bars remains locked the locking piece, so that the ladder can be folded in the following completely after a single actuation of the release lever.

Beim Auseinanderklappen der Leiter hingegen rasten die Sperrstücke der paarweise angeordneten Gelenke jeweils bei der nächsten Nut dann ein, wenn der Lösehebel losgelassen ist. When unfolding the circuit, however, the lock pieces of the paired joints latch respectively in the next groove, a then, when the release lever is released.

According werner single side ladder a further embodiment of the invention, the two release lever connecting rod is arranged laterally next to the rungs that are adjacent to the joints. This has the advantage for the service, werner single side ladder one and the same handle held the ladder and the release mechanism can be operated, which is extremely simplifies handling.

Aus sicherheitstechnischen Gründen ist die gestreckte Stellung der Holme gleichfalls durch Einrastung des Sperrstückes in eine entsprechend angeordnete Nut gesichert.
