Definitions

  • the present invention relates to an arrangement on a ladder according to the preamble of claim 1.
  • the invention specifically relates to a hand rail, adapted to be mounted on a ladder, a step ladder or the like.
  • the hand rail of GB 2,274,673 is not, contrary to the hand rail of the present invention, adjustable in the operative position to assume various inclinations in respect of the longitudinal direction of the ladder, but merely to be folded to a rest position to facilitate transport or storage thereof.
  • U.S. 2,640,641 discloses a step ladder having a bar, which is adjustable in the longitudinal direction of the ladder, and which may be raised from a resting position wherein the bar is extended alongside the ladder, to an operative position wherein the ladder is extended in parallel with, and slightly above, a side member of the ladder.
  • the bar In the operative position, the bar is longitudinally adjustable to extend beyond and above the top step of the ladder, more or less to function as an extension of the side member of the ladder.
  • the bar is locked in the raised, and eventually extended, operative position by means of two latches which are pivotally attached to the side member of the ladder and to the bar, respectively. In the raised position, the latches engage the bar to prevent it from sliding down towards the bottom end of the ladder.
  • the bar is not capable of adjustment into various and desired inclinations relative to the longitudinal direction of the ladder, or provides a similar free and unhindered grip by the hand when climbing the ladder, as is provided by the hand rail of the present invention through the freely supported, outer rail member.
  • the attachment of the bar of U.S. 2,640,641 is not, contrary to the attachment of the present invention, displaceable on the side member of the ladder, and the cited bar does not provide the desired security upon climbing because a downwardly directed load, from the hand gripping the bar, would seemingly cause the latches to lose the engagement with the bar, thereby releasing the bar from its position.
  • DE 33 16 839 A discloses a guard structure for a vertical ladder.
  • a circular cage is mounted to the vertical posts of the ladder.
  • the cage comprises longitudinal bars interconnected by means of arcuate horizontal members, the ends of which are clamped to the vertical posts of the ladder. Though mountable at a desired height, the cage is not disclosed to be extendable, neither would it be possible to attach the cage in alternative inclined positions relative to the ladder.
  • the present invention has for its object to provide a hand rail which offers a support for the user, not only upon climbing the ladder but also in work operations from the ladder, and specifically when working from the upper or top steps of the ladder.
  • a hand rail which is adjustable to assume various inclined positions in relation to the side member of the ladder, thereby to provide more space when climbing the ladder, and to save space during transport, resp.
  • a hand rail wherein the guide rail is freely suspended without hindering fastening means, whereby the hand of the user may be guided along the entire length of the rail without having to shift the grip upon climbing the ladder.
  • the invention provides:
  • the inner element 2 is connected to the outer element 5 through arch shaped sections, formed in the ends of the elements 2 and 5, respectively, so that the elements 2 and 5 are preferably integrally formed by bending a single work-piece.
  • Fig. 2 shows the end view of a fastening means 3 incorporated in the hand rail.
  • the fastening means 3 is designed to cooperate with a hand rail having an inner element 2 of circular cross section.
  • the fastening means 3 is shown separated and before mounting the hand rail to a ladder.
  • the fastening means 9 are clamped to the side member of a ladder.
  • the fastening means 9 comprises a bore for accommodation of an inner element 2' having a circular cross section.
  • a radial slit opening 10 is formed to cover the width of the fastening means 9.
  • At least one side of the fastening means 9, directed towards an end of the ladder, has one or more notches 11 formed to open in radial direction into the bore. Heels 12 are formed on the inner element 2' and designed to cooperate with the notches 11, thereby providing a bayonet lock for alternative attachment of a hand rail to a ladder.
  • the alternative fastening means 3' of fig. 4 comprises a brace 6' and a clamp 7', substantially designed as corresponding elements of the first fastening means 3.
  • the fastening means 3' is formed with a heel 13 to accommodate an inner element 2".
  • Said heel 13 is designed to cooperate with one or more longitudinal grooves 14, formed on the outside of the inner element 2".
  • the grooves 14 are preferably extended in the entire length of the inner element 2".
  • clamping fastening means may be designed to cooperate with side members of varying cross sectional profiles, or include spacing elements or inserts e.g. made of rubber or other elastic material, so as to be attachable to ladder sides of varying shapes.
