BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to apparatus for extending an enclosure formed by structure and provided with an opening for access to the enclosure from outside the structure, the enclosure providing protected internal space for domestic, commercial and industrial purposes, eg. garages, workshops etc.
FR-A-2576955, FR-A-1583741 and FR-A-1059516 disclose various forms of apparatus for extending an enclosure temporarily comprising movable structure forming a roof portion and sidewalls depending from the roof portion, the movable structure being guided for substantially rectilinear movement into and out of the enclosure by interengagement of wheels mounted on a sidewall of the enclosure with straight guide tracks in the sidewalls of the movable structure. Problems would arise if ground to be traversed by the movable structure as it is drawn out of the enclosure was not substantially flat and horizontal. In the case of the apparatus disclosed by FR-A-1583741 all the weight of the movable structure would have to be borne by the wheels mounted in the enclosure whereas the telescopic arrangement disclosed by FR-A-2576955, could not allow one of its modules to follow a carriageway which slopes up or down from the front of the enclosure, which is quite common with garages of houses in modern housing estates.
An object of this invention is to provide apparatus for extending an enclosure which is better able to follow the slope of a carriageway in front of the enclosure than the apparatus disclosed in the references discussed above.
SUMMARY OF THE PRESENT INVENTION
According to this invention there is provided apparatus for extending an enclosure temporarily comprising movable structure forming a roof portion and sidewalls depending from the roof portion and a wheel at the bottom of each sidewall for running on the ground as the movable structure is slid into and out of the enclosure, said movable structure being guided for substantially rectilinear movement into and out of the enclosure by interengagement of pivotally mounted means with straight guide track means wherein said guide track means are to be statically mounted on or formed by structure forming the enclosure, and said pivotally mounted means are pivotally mounted on the movable structure at a location thereon relative to the location of said wheels which allows the attitude of the movable structure relative to said guide track means to be adjustable automatically whereby to permit the movable structure to follow the slope of the carriageway as it is drawn out from within the enclosure or pushed back into the enclosure.
Preferred features of the apparatus are defined by the sub-claims.
BRIEF DESCRIPTION OF THE DRAWING FIGURES
One embodiment of this invention will be described now by way of example, with reference to the accompanying drawings, of which:
FIG. 1 is an orthogonal view of garage extension apparatus in a position to extend the interior of a garage, a portion of the front of the apparatus being broken away to show part of its interior;
FIG. 2 is a view in perspective from within the garage extends ion apparatus of the region A of the apparatus shown in FIG. 1, drawn to a larger scale than FIG. 1 and with the front door slightly ajar;
FIG. 3 is a view in perspective, from the rear of the apparatus, of the region B of the apparatus shown in FIG. 1, drawn to a larger scale than FIG. 1; and
FIG. 4 is a typical cross-section of the roof panel of the apparatus shown in FIGS. 1-3 along a line extending from the front to the rear of the apparatus.
DESCRIPTION OF A PREFERRED EMBODIMENT
FIG. 1 shows brickwork which forms an enclosure (10) in a building for use as a garage.
A channel section extrusion (11,12) is mounted generally horizontally within the enclosure (10) with its mouth facing inwardly, each of the extrusions (11,12) being mounted on a respective side wall of the enclosure (10) near the ceiling of the enclosure (10).
Movable structure (13), which comprises a flat roof panel (14), side walls (15,16), and an up-and-o
