Definitions

  • the present invention relates to an arrangement for enabling the installation of a loft ladder subframe in an aperture of a ceiling.
  • a traditional loft ladder hatch frame is created by cutting away a portion of plasterboard between two ceiling joists and framing out a rectangular aperture by nailing or screwing two pieces of timber transverse the ceiling joists to define the loft ladder hatch frame.
  • loft ladder subframe assembly we mean a rectangular frame carrying an openable trap door. The trap door may carry the multi-sectional loft ladder folded neatly thereon.
  • the ceiling aperture in which the loft ladder is being placed is slightly larger than the ladder subframe itself, a means of supporting the weight of the subframe assembly is required for installation purposes. Once the loft ladder subframe assembly is initially secured, the loft ladder subframe can then be permanently mechanically coupled to the loft ladder hatch frame for a final and permanently secured fitting.
  • this method of initially supporting the weight of the loft ladder subframe assembly is achieved by an operator carrying the loft ladder subframe assembly into the attic and subsequently lowering the loft ladder subframe assembly into the ceiling aperture from above. A second operator temporarily holds the subframe assembly in place until the installer in the attic fixed the subframe assembly to the hatch frame using screws.
  • the conventional method of installing loft ladders using two operators is no longer financially viable.
  • a further conventional method of installing the loft ladder subframe assembly is by the use of temporary support battens placed along the underside of the ceiling opening so as to protrude a small distance into the opening. These support battens are coupled to the ceiling plasterboard by screws and the loft ladder subframe is lowered from above to be initially supported atop the slightly protruding battens. Subsequently the subframe is nailed and/or screwed to the ceiling joists for permanent installation. Following the installation, the support battens are removed.
  • This system provides a major safety risk as the trapdoor of the loft ladder subframe assembly must be capable of opening in the initially supported position to allow the installer access to the subframe.
  • the battens can only protrude into the ceiling aperture a very short distance. This means that the length of the overlapping contact surfaces of the temporary battens and the subframe is short. Any unexpected lateral force applied to the subframe assembly could easily slide the subframe off the battens resulting in the full weight of the loft ladder subframe assembly falling on the installer or other person below.
  • installation brackets are secured to the corners of the loft ladder subframe and a horizontal steel flat bar is subsequently attached to each. Following the attachment of the flat bars to the brackets, this method requires that a single user lowers the loft ladder into the ceiling opening from above with the installation brackets and flat bar combination adjusted so that the flat bars sit securely on the hatch frame on the loft floor. This maintains the position of the loft ladder subframe flush to the ceiling until the loft ladder subframe assembly can be permanently fixed to the ceiling joists.
  • US3901353A1 discloses a support arrangement showing the features of the preamble of claim 1.
  • the object of this present invention is to obviate the above problems and provide a quick and easy support arrangement for initially supporting the weight of a loft ladder subframe assembly, to allow the permanent installation of the loft ladder subframe assembly.
  • the present invention provides a support arrangement for taking the weight of a loft ladder subframe assembly as it is initially placed into a hatch frame defining an aperture in the ceiling, the support arrangement comprising hatch frame protrusion means capable of protruding a short distance into the aperture from the hatch frame, the support arrangement further comprising loft ladder subframe protrusion means capable of protruding a short distance from the loft ladder subframe, the hatch frame protrusion means and the loft ladder subframe protrusion means being capable of engaging so that the hatch frame protrusion means supports the weight of the loft ladder subframe assembly.
  • the hatch frame protrusion means are capable of protruding a short distance into the aperture from the frame members of the hatch frame, most preferably from the inside vertical surface of two mutually opposing frame members.
  • the loft ladder subframe protrusion means are capable of protruding a short distance from the frame members of the loft ladder subframe, most preferably from the outside vertical surface of two opposing frame members.
  • the hatch frame protrusion means are locatable below the loft ladder subframe protrusion means when the loft ladder subframe assembly is located in the hatch frame for securing.
  • the hatch frame protrusion means and the loft ladder subframe protrusion means are capable of overlapping so that the hatch frame protrusion means supports the weight of the loft ladder subframe assembly via the overlap between the loft ladder subframe protrusion means and the hatch frame protrusion means in use.
  • the loft ladder support arrangement utilising a hatch frame protrusion means extending into the ceiling opening in combination with a loft ladder subframe protrusion means enables a user to install a loft ladder from below i.e. without the need to enter into the attic space. This is achieved by a slight tilting of the loft ladder subframe assembly in the vertical plane to allow the loft ladder subframe protrusion means to pass by the hatch frame protrusion means so as to fit the loft ladder subframe assembly into the ceiling aperture defined by the hatch frame.
  • the loft ladder subframe assembly is then tilted back to a generally horizontal plane so that the loft ladder subframe protrusion means overlap the hatch frame protrusion means and the loft ladder subframe assembly is lowered so that the loft ladder subframe protrusion means engage onto the hatch frame protrusion means and engage to support the weight of the assembly.
  • Placing the loft ladder subframe assembly in position from below also enables the user to utilise their leg and gluteal muscles while maintaining a vertical trunk during the lift of the loft ladder into position. As a result this minimises injury to an individual's back. This alleviates the lifting and lowering complications associated with the open chain lifting of the prior art that will occur when the loft ladder is being lowered into position from above the ceiling opening.
  • the loft ladder support arrangement is a permanent fixture between the loft ladder subframe assembly and the hatch frame, providing an auxiliary securing feature for the loft ladder once permanently installed.
  • a loft ladder support arrangement that utilises overlapping protrusion means as an initial weight supporting arrangement prior to permanent fixing provides for a simple and rapid pre-installation process without the requirement for any complex mechanical fixtures and fixings.
  • the hatch frame protrusion means protrudes from the inside vertical surface of two mutually opposing frame members of the hatch frame.
  • the loft ladder subframe protrusion means protrudes from the external vertical surface of the two opposing frame members of the loft ladder subframe.
  • the loft ladder support arrangement utilises two pairs of mutually opposing hatch frame and loft ladder subframe protrusion means.
  • the overlapping protrusion means support the loft ladder subframe assembly at a desired vertical position within the ceiling. This enables a user to then permanently and securely affix the loft ladder subframe assembly to the hatch frame with screws or the like to complete the loft ladder installation.
  • the loft ladder subframe protrusion means is fixed to the hatch frame protrusion means.
  • the loft ladder subframe protrusion means is mechanically coupled to the hatch frame protrusion means.
  • the support that is provided by the hatch frame protrusion means supports the weight of the entire loft ladder subframe assembly. This maintains the loft ladders position to enable the installer to permanently affix the subframe to the ceiling framing members of the hatch frame.
  • the bottom surface of the hatch frame protrusion means is flush to the ceiling plasterboard.
  • the hatch frame protrusion means that is flush to the ceiling plasterboard results in no further finishing or adjustment being required subsequent to installing the loft ladder subframe assembly and this provides for the desired aesthetic finish.
  • the hatch frame protrusion means is a batten fixed to mutually opposed framing members of the hatch frame.
  • the hatch frame protrusion means is a timber batten.
  • the hatch frame protrusion means is a bracket.
  • the hatch frame protrusion means comprises a timber batten and a bracket on mutually opposing framing members of the hatch frame.
  • the hatch frame protrusion means comprises a batten fastened to the external vertical surface of two mutually opposing framing members of the hatch frame.
  • the hatch frame protrusion means is temporarily pre-installed to the loft ladder subframe assembly for ease of assembly and installation.
  • the hatch frame protrusion means comprises two battens being transferrably installed from the external surface of the loft ladder subframe to the hatch frame.
  • this enables the hatch frame protrusion means to be pre-manufactured to size in the factory allowing for a quick and easy assembly of the loft ladder subframe assembly at the factory and subsequently an easy installation process on-site.
  • This also eliminates any human errors in measuring the protrusion means to size that may occur on-site allowing the loft ladder subframe assembly to remain flush with the ceiling.
  • the loft ladder subframe protrusion means is fixed to the external boundary of the loft ladder subframe.
  • the loft ladder subframe protrusion means is mechanically coupled to the external vertical surface of two opposing frame members of the loft ladder subframe.
  • the loft ladder subframe protrusion means is characterised as at least two battens.

  • the loft ladder subframe protrusion means is adjustable between two positions; a protruding position for initially supporting the loft ladder subframe assembly on the hatch frame protrusion means and a retracted installing position for allowing the loft ladder subframe assembly to slide past the hatch frame protrusion means during installation.
  • the protrusion means is adjustable between the retracted installing position and the protruding position via biasing means.
  • the loft ladder subframe protrusion means comprises a bracket mountable on the external vertical surface of the loft ladder subframe and a hinge moveably coupled to the bracket between an installation position substantially flat against the bracket and a protruding position for supporting the loft ladder subframe assembly on the hatch frame protrusion means.
  • the hinge is normally biased into the protruding position by a biasing member acting on the hinge.
  • the hinge is operable between the protruding position and the installation position by engagement with the hatch frame protrusion means as an operator pushes the loft ladder subframe assembly into the aperture defined by the hatch frame from below.
  • the hatch frame protrusion means tapers towards the ceiling.
  • the tapered hatch frame protrusion means provides less resistance to the hinge as it pivots smoothly away from its protruding position to the retracted installing position.

  • the biasing means is a spring.
  • the biasing means utilises a bolt and spring action.
