Definitions

  • the present invention relates to a collapsible ladder and ladder apparatus, in particular a telescopic ladder for suspension from an elevated position, and more particularly to a wall mountable ladder, for use as an emergency fire escape.
  • the safest or only available option may be to exit the property via an upstairs window or balcony.
  • a ladder is usually required in order to do this safely. However, this would require having a readily available ladder in the property or relying on a third party to deliver a ladder. In order to keep a ladder upstairs for emergency use it needs to be capable of being stored away in a compact manner, as use of a standard ladder is generally not a practical option due to space considerations.
  • Conventional ladders for use as a fire escape include rope or wire cable ladders which are capable of being folded away and stowed when not required. In use, however, these rope or wire cables can feel unstable and difficult to climb down when in a heightened state of emergency. This is even more the case when carrying or helping young children. There is therefore a need for a ladder for use as a fire escape which addresses the problems of conventional ladders. There is also a need for a ladder which is capable of compact storage when not in use.
  • An aim of the invention is to provide a ladder which attaches securely to the infrastructure of the property, for example to an upstairs exit, such as for example a window.
  • Another aim is to provide a ladder which can be deployed (assembled and attached) to an upstairs window (exit) quickly and securely.
  • UK Patent GB 2 506 835 discloses a ladder for use as a fire escape having two stiles comprising telescopically collapsible tube sections, a plurality of rungs each secured to the upper end of two tube sections, each of the two sections being part of a respective one of the two stiles.
  • UK Patent GB 1 912 897 discloses improvements in ladder hooks.
  • Dutch Patent Application NL1026402C discloses a holder device for supporting extendible ladder against a wall.
  • UK Patent GB18971 1618 discloses a flexible ladder for a fire escape.
  • European Patent Application EP 2 319 728 discloses a locking system for a fixed ladder.
  • UK Patent Application GB 2 301 138 discloses a fire escape device.
  • UK Patent Application GB 2 532 423 discloses a cantilever mounted loft ladder with spring bias.
  • the present invention arose in order to overcome problems suffered by existing devices.
  • a collapsible safety ladder for deployment by suspension from an elevated location comprising: a plurality of concentrically stacked rail sections; and a plurality of rungs, each rung is connected to a pair of parallel rail sections by means of a sliding connection which permits movement of a rung from a first stacked position to a second deployed position by means of gravity.
  • the safety ladder provides a secure and stable means of exit from a location such as a property which can be deployed from an elevated position such as a window or balcony towards the ground or a lower level of a building, vehicle, vessel or structure.
  • the safety ladder deploys telescopically downwards when suspended so that the rail sections are deployed by unstacking in downwards direction under the force of gravity or someone pulling downwards on it; although preferably it extends under its own weight. In this way each rung can only slide so far as an end connector permits, thus locking the rung in a fixed position once deployed.
  • this arrangement of having sliding connectors permits the stacked ladder to deploy downwards when released and to bear the weight of a user whilst the rungs remain locked.
  • Each rung locates in a fixed position on a rail section by means of the sliding connection that restricts movement of the rung along rail section when the rung reaches the second position.
  • the sliding connection comprises: a pair of end connectors provide at opposed ends of each rung; each end connector passes around at least part of the perimeter of each rail section; wherein the rail sections are nested and so are dimensioned to have an increasing cross section from a proximal end to a distal end, whereby as the safety ladder is deployed, each rung is deployed to a position on each rail section at which the diameter or perimeter of the end connector corresponds to the cross section of the rail section, thereby locking the rung in position. At a point where the perimeter of the rail section is greater than the opening of the end connector the rung is prevented from sliding further down the rail section and is thereby locked in place.
  • each rung end may include a pin received by a channel on a rail.
  • the pin is able to slide up and down the rail from a first (stowed) position to a second (deployed) position.
  • the end of the channel provides a stopper to restrict movement of the pin in the channel and thereby prevent movement of the rung beyond the channel end during use.
  • the safety ladder is provided as a component of a ladder apparatus for providing an escape route, the apparatus comprising: the safety ladder, an attachment member having at least one attachment portion attachable to a surface, such as a surface or part of an infrastructure on an exit of a property, and at least one anchoring portion for receiving a ladder, wherein the anchoring portion is moveable between a first collapsed configuration, when not in use, to a second operative configuration; the attachment member has at least one pivot for changing from the first configuration to the second configuration; and the ladder comprises a first ground engaging end and a second opposed end, each of the second opposed ends having engagement means for releasable engagement with the anchoring portion of the attachment member.
  • the escape route may be an exit from any elevated space which includes a property, a vessel, or another structure, the structure being natural such as a tree, or man-made.
  • the ladder is telescopic and is therefore readily deployed from a collapsed configuration to a deployed extended position.
  • the configuration of the ladder is such that the ladder is collapsible from the extended state, when in use, to a collapsed state when being stored.
  • the ladder may therefore be able to be stored away in a compact manner when not in use.
  • the rails have a common axis so as to coaxially telescope.
  • the telescopic nature of the ladder enables the ladder to minimise in size, and adds to stability, wherein the lower portion of the ladder rail is consequently larger in diameter/perimeter.

  • the safety ladder is formed from a strong, durable fireproof material, such as metal, metal alloys or synthetic plastics. Ideally the ladder portion is also lightweight so as to permit easy movement from a remote stowed location to the in use location.
  • the materials from which the ladder is formed are also selected to prevent twisting when the ladder is extended.
  • the ladder potions namely rails and rungs, are shaped and dimensioned for strength and stability.
  • the rails and the rungs may include thickened regions or ribs for additional strength.
  • All or part of the ladder may be formed from metal, metal alloy such as: mild steel, aluminium, synthetic plastics, or a composite or other high strength material such as fibreglass, carbon fibre, or a combination thereof.
  • the ladder may comprise rope linking one rung to another and or one rail to another.
  • the rope may serve as a failsafe in the event of a rung failing or becoming damaged in use.
  • the rope may be a nylon rope, arranged to enable the components of the ladder to collapse and extend.
