Abstract

A rolling platform (10) comprises a static frame (11) fixed to a building by clamps (17), and a movable frame (20) telescopically slidable between a retracted position within the building and an extended position extending outwardly of the building. The movable frame (20) is carried by rollers (30, 31). Further rollers (32) are positioned to engage the movable frame (20) when retracted in such a manner that the movable frame (20) can be of greater length than the static frame (11).

Description

Rolling Platfor
The present invention relates to a rolling platform used particularly, but not exclusively, in the building construction industry to provide access platforms extending past the edge of floors of buildings during their construction, the rolling platform being cantilevered from the end of the floor and also having the ability to fully retract from its extended position.
Conventional rolling platforms used for providing access platforms off the edge of floors of buildings during their construction, comprise a static frame and a rolling frame, the static frame extends partly from the edge of the floor and the rolling frame can be extended even further from the edge of the floor.
However, the disadvantage of these conventional platforms is that the static frame extends outwardly from the floor and this extension means that the rolling frame (and the whole platform) can not be retracted flush with the edge of the floor, during use.
It is one object of the present invention to provide a platform wherein the rolling frame fully retracts to be flush with the edge of the floor, whilst still being supported by the static frame.
According to the present invention, there is provided a roller platform for use in providing access platforms extending past the edge of floors of buildings during their construction, the platform comprising: a first, static frame which is securable to the building; a second, movable frame which is telescopically slidable with respect to the first frame between an extended and a retracted position; and roller means positioned between the first frame and the second frame to permit relative sliding movement between the frames; and wherein further roller means are provided, said further roller means being arranged to engage and support the second frame as it is moved toward and is in the fully retracted position.
Preferably, the first frame is an outer frame and the second frame telescopes within the outer frame.
Preferably also, the inner frame is of greater length than the outer frame. The first-mentioned roller means may comprise rollers at the rear of the inner frame bearing on the outer frame, and rollers at the front of the outer frame bearing on the inner frame; and the further roller means may comprise rollers at the rear of the outer from which engage with a rail at the rear of the inner frame as the latter is retracted.
Preferably, when the second frame is fully retracted, no part of the rolling platform extends outwardly (away from the building) from the edge of the floor.
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings, in which:
Figs la and lb show cross-sectional elevational and plan views respectively of the rolling platform of the present invention, the platform being in the extended position; Fig 2 is a cross-sectional side view of an inner frame of Fig 1, to an enlarged scale; Fig 3 is a plan view corresponding to Fig 2; Fig 4 is a cross-section on the line 4-4 of Fig 1; Fig 5 is a detail of Fig 4 to an enlarged scale; Fig 6 is a side view of parts of the inner frame in more detail; Fig 7 is a plan view corresponding to Fig 6; Fig 8 is a side view of parts of the outer frame in more detail ; Fig 9 is a cross-section on the line B-B of Fig 8; Fig 10 is a cross-section on the line C-C of Fig 8; Fig 11 is a plan view corresponding to Fig 8; and Fig 11a is a cross-section on the line A-A of Fig 11 to an enlarged scale.
Referring to the drawings, there is illustrated a rolling platform 10. The rolling platform 10 comprises an outer static frame 11 and an inner frame 20. The outer static frame 11 is in the form of two I -sections 12a and 12b joined by a plate 14 to form a generally channel-shaped element. The inner frame 20 is in the form of two I-sections 21a and 21b joined by a plate 22 to form a generally channel -shaped element.
The inner frame 20 is telescopically slidable within the outer frame 11 and can slide between an extended (see Fig. la) and a retracted position.
The rolling platform 10 is used in the building industry to provide an access platform which extends past the edge 15 of floors of a building during its construction.
The rolling platform 10 is clamped to the building by placing the platform 10 on the floor with a first end 16a flush with the edge 15 of the building. The platform 10 is then secured in the clamped position by way of a number of clamping pillars 17a and 17b (others not shown) which clamp between the outer static frame 11 and the ceiling (not shown) .
The inner frame 20 slides within the outer static frame 11 by roller means in the form of a pair of first rollers 30 and pairs of second and third rollers 31a and 31b, which are all positioned between the inner frame 20 and the outer frame 11 and permit relative sliding movement between the respective frames 11, 20 thus allowing the inner frame 20 to telescopically move out of the outer frame 11, thus providing an access platform which extends outwardly (away from the building) from the edge 15 of the floor.
A further roller means in the form of rollers 32 is fitted to the outer frame 11 and is arranged to engage a track 40 provided on the inner frame 20 to provide support for the inner frame 20 when it is retracted and the rollers 31a and 31b no longer engage with the outer frame 11 due to the outer frame 11 being shorter in length than the inner frame 20.
Lateral guidance is provided by vertical rollers 33 located near the front of the fixed frame 11, and by axially spaced vertical rollers 34 and 35 located toward the rear of the slidable frame 20. the rollers 35 being sufficiently inboard to remain in engagement when the slidable frame 20 is fully retracted.
Alternatively, if the inner frame 20 and the outer frame 11 are similar in length, the further roller means 32 can still be utilised to give additional support to the inner frame 20 even though the rollers 31a and 31b may still be in contact with the outer frame 11.
The rolling platform described above, provides a platform 10 which is positioned flush with the edge 15 of the floor and which permits the inner frame 20 to fully retract within the outer frame 11 such that when fully retracted, no part of the rolling platform extends outwardly (away from the building) from the edge 15 of the floor.
Modifications and improvements may be made to the foregoing without departing from the scope of the present invention.
