Definitions

  • the present invention relates to step ladders used in domestic and professional services of all sizes and the ability to prevent them from tipping or falling to their side when in use.
  • step ladders are widely known and they provide the ability for a person to gain access to certain heights during general day to day chores or when work is being done, such as painting and decorating or building works.
  • Stabiliser devices are known in the prior art. More specifically, these devices which are moreover devised and used for the purpose of stabilising ladders, are known to consist familiar, derived and obvious configurations, notwithstanding the myriad of designs presented by the volume of prior art which have been developed.
  • the design disclosed herein detracts from the conventional concepts and designs of the prior art, and so provides an apparatus primarily developed for the purpose of maintaining a step ladder in an upright configuration when in use and enabling said ladder to be used in more confined spaces with allowance made for opposing side areas and space around them.
  • an improved step ladder stabiliser This is designed to provide advantages when compared to the prior art.
  • a foot which is of a suitably sized form having an upper and lower surface, purchase and gripping means affixed to the lower surface to prevent the foot from moving or slipping when placed on a recipient surface and a bracket coupled to the upper surface and extended upwards therefrom.
  • a tubular leg is provided which extends from the foot, this is located and movably pivoted to the foot by means of a pin hinge to enable correct adjustment for footing in differing floor locations.
  • the lower leg and foot ensemble includes an elongated straight rigid cylindric lower segment having a closed lower end and an open upper end with the lower end pivotally coupled to the bracket of the foot to provide an initial pivot joint and with the upper end having a pinning hole disposed therethrough.
  • the leg also includes an elongated straight rigid cylindric upper segment having an upper end and a lower end, both the upper and lower portions of the leg are movably hinged centrally, via a lateral twin pinned hinge, incorporating a male link plate.
  • This centrally located hinge enables the mid-section of the two adjoined leg tubes to fold varyingly at that juncture, for ease of storage and delivery of the central leg when being used.
  • the centrally positioned hinge is derived of a male link plate which is a pill shaped planar and has two holes which correspond with holes provided to the closed ends of the two upper and lower leg tubes and these two aligned holes are held via means of through pinning.
  • This joint advantageously enables the tubular leg to fold upwards vertically for storage, as shown and once extended is held in place by a hollow sprung locking tube, which is passed fully over the male link late, utilising a spring pin to secure it, in provided holes.
  • an attachment point for the whole leg coupled to a stepladder at its upper hand rail is an attachment point for the whole leg coupled to a stepladder at its upper hand rail.
  • This is a bracket or hinge connector method which is attached to the stepladder by clamping means axially rotatably mated with the first section of the tubular leg and pivotally coupled to the upper end of the upper leg to thereby create a second swivel joint for allowing the upper leg to be pivoted and rotated with respect to a stepladder when coupled thereto.
  • a pair of support struts connect from each side of the lower portion of the hand rail of a step ladder body and will extend outward to couple with the tubular leg. These are also clamped via exacting means to the tubular leg to the step ladder rail by hinge connectors, which rotate and swivel at an initial joint.
  • the two tubular struts locate and attach to the lower portion of the tubular leg via a through bracket with swivel and pivot means at attachment on both sides, as shown in later accompanying Figures.
  • the two support struts also extend down with it and maintain the position and stability of the leg, in its two extended and held sections.
  • the struts have fixture to both lower opposing sides of the folding step ladder, being fixed to the hand or main rail of the step ladder, into which the steps themselves are inserted. Therefore, when the step ladder is to be opened, the 'central' tubular leg is folded down and forms a single member by means of its aforementioned central male link plate and a locking tube ensemble, because the opposing ends of the two strut tubes are attached to the now straight lower parts of the main central support leg, the struts naturally extend outward with it in a somewhat 'automatic' assembly, as the step ladder is opened.
  • each of the tubular struts and the leg variably pivot or swivel in a rotational and/or tilting manner, when the ensemble of parts are stored, the opposite effect and action occurs wherein; the tubular support leg folds upwards, as the sprung pin locking tube is slid away at its central male plate connecting joint, the two strut tubes also fold into a vertical position as they are attached to it and the step ladder, all parts when in closed position for storage are vertical to the closed frame of the step ladder.
  • the central main leg is held closed and folded vertically in a plastic pressure clip which cups and holds its tubular body and therefore the attached two strut tubes and the assembly are also held for storage.
  • a supporting leg which extends outward to one or either side of a step ladder.
  • the leg folds up for storage and down for usage, this folding made possible by a centrally positioned multi-purpose joint.
  • two support strut tubes are provided at angles to the leg and step ladder, to each of which they are attached and also fold with the leg up and down due to their attachment to it, at a multi-purpose joint to the lower area of the supporting leg.
  • the ensemble provides stability to the step ladder for prevention of the step ladder tiling or becoming unstable and the person falling at height and is advantageously able to instantly fold away and remain in place on the step ladder for storage.
  • An even further object of the present invention is to provide a new and improved step ladder stabiliser which is susceptible of a low cost of manufacture with regard to both materials and labour, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such a step ladder stabilizer economically available to the buying public.
  • Still yet another object of the present invention is to provide a new and improved step ladder stabiliser which provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of the disadvantages normally associated therewith.
  • Even still another object of the present invention is to provide a new and improved step ladder stabiliser for maintaining a step ladder in an upright configuration when in use.
  • a new and improved step ladder stabiliser comprising a folding and finely adjustable leg having an upper end and a lower end; coupling means for coupling the upper end of the leg to a stepladder and allowing the leg to be pivoted and rotated with respect to the stepladder; two struts provide the limiting means for limiting the extent to which the leg can be pivoted and rotated, helping also to position the main leg and also enable its folding upward after usage and a foot pivotally coupled to the lower end of the leg and having gripping means extended downwards therefrom for preventing the foot from moving or slipping when placed on a recipient ground or floor surface.

Abstract

La présente invention concerne un stabilisateur d'escabeau qui permet de garantir qu'un escabeau reste droit lors de son utilisation et qui comprend un ensemble élément de pliage qui peut être stocké sur l'escabeau concerné, puis qui se replie avantageusement dans une action automatisée lorsque l'escabeau est ouvert. L'invention comprend un montant de support tubulaire central en deux sections, pourvu d'un pied, qui s'étend à partir du côté de l'escabeau au niveau de sa barre d'appui supérieure, et de deux béquilles tubulaires de support inférieures, qui s'étendent également à partir de l'escabeau mais des deux côtés, de manière à être adjacentes latéralement à la section inférieure du montant de support au niveau de deux points. Des articulations tournantes et pivotantes au niveau des extrémités du montant et des béquilles permettent le réglage du montant et de son pied de préhension, ainsi que le pliage rapide lorsque l'escabeau n'est pas utilisé.
