Description:
TOOLS FOR A HOLDER FOR EQUIPMENT USED WHEN FURBISHING OR REFURBSHING ROOMS OF BUILDINGS

FIELD OF THE INVENTION

Aspects of the present invention relates to tools for supporting and/or operating equipment used for furbishing or refurbishing rooms of buildings. The tools may be for only supporting equipment, or for only operating equipment, or for both supporting and operating equipment. The tools are used together with a holder for the

equipment. The invention also relates to a method for furbishing or refurbishing rooms of buildings.

BACKGROUND OF THE INVENTION Holders for equipment are known, such as holders for either plasterboard, for elongate sander like giraffe® sanders and other equipment used when furbishing or

refurbishing rooms of buildings. Giraffe® is a trademark registered by the company Flex Elektrowerkzeuge GmbH. In the following, giraffe® sander will be used for elongate sanders in general, also elongate sanders from other companies than the company Flex.

Holders for such equipment have supports for one single piece of equipment, such as one holder for plasterboard to be mounted at a ceiling, another holder for a giraffe® sander for sanding the plasterboard and sanding any filling of the plasterboard, and yet another for possible lighting equipment. Thus, many different holders are needed.

The equipment supported and/or operated may be purely hand-operated equipment or may be combined power-operated and hand-operated equipment. Purely hand- operated equipment may be rolls of ceiling covering to be applied by hand to a ceiling. Combined power-operated and hand-operated equipment may be a giraffe® sander for power-operated sanding of a ceiling, while being manually displaced along the ceiling.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a holder not limited to a single use for a single piece of equipment. One object of the invention may be to limit the need for different holders for different single pieces of equipment for each single operation. Another object of the present invention may be to provide a holder for holding different other equipment than the equipment, which the known holders are capable of holding singularly. Still another object may be to provide a holder, which makes operation of the equipment easier for the user, and possibly makes operation of the equipment economically better for the user.

At least one of the objects of the invention is obtained by a sander support for a giraffe® sander used when furbishing or refurbishing rooms of buildings, where the sander support has at least two support brackets capable of supporting an elongate rod between distal ends of a giraffe® sander, where the at least two support brackets are capable of fastening the elongate rod in cavities of the at least two support brackets, and are provided with a fastening mechanism for forcing the at least two support brackets towards each other, when the elongate rod of the giraffe® sander is to be fastened to the sander support, where the sander support also has a mounting bracket for mounting the sander support to an upright strut of a holder for the giraffe® sander, where the mounting bracket, when the sander support is mounted to the upright strut of the holder, extends downwards along a top end of the upright strut of the holder, and where the mounting bracket prevents the sander support from pivoting around a longitudinal axis along the upright strut of the holder, and where the sander support has a hinge between at least one of the support brackets and the mounting bracket, and where the hinge, when the sander support is mounted to the upright strut of the holder, allows the at least two support brackets to pivot around a non-vertical axis in relation to the mounting bracket. A sander support according to an aspect of the invention has the advantage of a giraffe® sander capable of being supported and adjusted to different angles and orientations in relation to the holder. The angles of adjustment of the giraffe® sander depends on the height and inclination of the ceiling or walls to be sanded. Eventually, the giraffe® sander may be operated by only operating manually the holder itself. When using a sander support according to the invention, operating the sander needs not to be performed by operating manually both the holder and the giraffe® sander at the same time.

A preferred embodiment of a sander support according to the invention, each of the at least two individual support brackets includes a cavity for supporting the longitudinal rod extending between the distal ends of the giraffe® sander, where each of the at least two support brackets includes at least two flanges extending laterally outwards from sides of the cavity, preferably from boundaries of the cavity, where each of the flanges has a fastening mechanism for forcing the at least two support brackets towards each other, and where the fastening mechanism is adjustable for adjusting a mutual distance between the at least two support brackets to a cross-sectional dimension of the longitudinal rod between the distal ends of the giraffe® sander to be supported by the support unit. Two individual support brackets results in a mutual distance and a mutual forcing against each other of the two support brackets may be provided individually, depending on the cross-sectional shape and/or on the cross- sectional area of the elongate rod of the giraffe® sander, and to be supported by the two support brackets.

At least one of the objects may be obtained by a steering grip for equipment used when furbishing or refurbishing rooms of buildings, where the steering grip has a handlebar to be operated by a user, and where the steering grip also has a mounting bracket for mounting the steering grip to an upright strut of a holder for the equipment, where the mounting bracket is capable of extending partly around the upright strut of the holder, and where the mounting bracket has a fastening mechanism for fastening the mounting bracket to the upright strut of the holder, and where the handlebar, when the steering grip is mounted to the upright strut of the holder, extends laterally in relation to the upright strut of the holder, and where the upright strut of the holder and the holder itself are capable of being operated by steering, when the user is operating the handlebar.

A steering grip according to an aspect of the invention has the advantage of the equipment being capable of being steered with the handlebar placed along the upright strut of the holder in a position being economically better for the user. Eventually, the equipment may be steered by manually only steering the steering grip itself.

In an embodiment of the steering grip according to the invention, the handlebar has a first end for a grip of one hand by the user and a second end for a second grip by the user, where the first grip end, when the steering grip is mounted to the upright strut of the holder, extends laterally away and along a first direction in relation to the upright strut of the holder, where the second grip end, when the steering grip is mounted to the upright strut of the holder, extends laterally away and along a second direction in relation to the upright strut of the holder, and where the first direction is away from and at one side the upright strut of the holder, and the second direction is away from and at another side of the upright strut of the holder, as seen by the user when the user is operating the handlebar. The steering grip having a first grip end and a second grip end and provided as disclosed above, makes it possible for the user to steer the holder by use of both hands and by holding both hands in economically correct positions.

In another or a further embodiment of the steering grip according to the invention, a distance between outermost positions of the first grip end and the second grip end is at least 250 mm, preferably at least 500 mm, possibly at least 750 mm, preferably at the most 1000 mm, and where the first grip end extends along a first line and the second grip extends along a second line, and where an intersection between the first line and the second line constitutes an angle between 0 degrees, at which angle where the first grip end and the second grip end extends laterally in parallel, and 180 degrees, at which angle the first grip end and the second grip end extends laterally in opposite directions.

In a still further and preferred embodiment of a steering grip according to the invention, the intersection between the first line and the second line constitutes an acute angle between 30 degrees and 180 degrees, possibly between 90 degrees and 180 degrees, preferably between 120 degrees and 180 degrees, and where a distance between the outermost positions of the first grip end and the second grip end of between 500 mm and 1250 mm. The steering grip having an acute angle and having a certain distance between the first grip end and the second grip end, provides an economically good steering grip making steering of the holder easier and better to the user.

A possible use of the steering grip according to the invention is, where the equipment used when furbishing or refurbishing rooms of buildings and operated by the steering grip is a giraffe® sander. A giraffe® sander may be more easily, more efficiently and economically more correctly operated when using a steering grip.

In a preferred embodiment of the steering grip according to the invention, the steering grip has a connection rod with a length between 100 mm and 500 mm and extending laterally between the handlebar and the mounting bracket, where the connection rod connects the handlebar and the mounting bracket and establishes a distance between the handlebar and the mounting bracket, so that a distance likewise is provided between the user and the upright strut of the holder, when the user grabs the handlebar. A distance between the handlebar and the mounting bracket results in feet of the user not colliding with base legs of the holder, when operating the holder by the steering grip. In a possible embodiment of the steering grip according to the invention, the handlebar is non-straight, preferably being continuously curved, and where a distance between a position along the handlebar and the upright strut of the holder, when the steering grip is mounted to the upright strut of the holder, is larger at positions along the handlebar being distant from the mounting bracket compared to positions along the handlebar being proximate to the mounting bracket. A curved handlebar results in the user being able to grab the handlebar with hands at various positions along the handlebar, depending on which position of the user's hands is the most efficient positions and/or which position of the user's hands is ergonomically the most correct positions.

At least one of the objects of the invention may be obtained by a handle rod for a sander support, where the handle rod is elongated and has a length between 500 mm and 2000 mm, where the handle rod has one end of the handle rod being bend along one angle in relation to a straight extension of the handle rod, where the handle rod has another end of the handle rod being bend along another angle in relation to the straight extension of the handle rod, where the one end or the other end of the handle rod is capable of being inserted into a handle support of a sander support in order to operate the sander support, and where the one angle is larger than the other angle so that the handle rod may extend from the handle support along at least two different extensions.

A handle rod according to an aspect of the invention has the advantage, that equipment may be handled by the handle rod in combination with a support for the equipment and in relation to the holder, where it may be difficult to operate the equipment by only operating the holder, onto which the equipment is mounted.

According to a possible embodiment of the invention, a sander support according to an aspect of the invention has a handle rod according to an aspect of the invention . A giraffe® sander may be operated by the handle rod and in relation to the holder, where it may be difficult to operate the giraffe® sander by only operating the holder onto which the giraffe® sander is mounted, possibly by grabbing only the hand-driven wheel. At least one of the objects of the invention may be obtained by a support board for equipment used when furbishing or refurbishing rooms of buildings, wherein the support board has a mounting plate, said mounting plate capable of supporting the equipment to be used when furbishing or refurbishing rooms of buildings, where the mounting plate has at least two mounting brackets extending along and around, alternative extending along and interior to an internal surface, of the top of the upright strut of the holder, a top of an upright strut of the holder, when the support board is mounted to top of the upright strut of the holder.

The upper strut 6 is supported by and is displaceable telescopically within the lower strut 5. The holder has a hand-operated wheel 8 to be turned for operating a mechanism (not shown) provide inside the upright strut 5. The mechanism is for telescopically raising or lowering the upper strut 6 in relation to the lower strut 5. Turning the hand-operated wheel 8 clockwise raises the upper strut 6 in relation to the lower strut 5, and turning the hand-operated wheel 8 counter-clockwise lowers the upper strut 6 in relation to the lower strut 5.

A top end 9 of the upper strut 6 is intended for engaging with a plasterboard support (not shown), when the holder is used in a known manner. In the embodiment shown, the top end 9 has an outer rectangular cross-sectional shape seen in a plane perpendicular to a longitudinal axis rod the upper strut 6. Preferably, the top end 9 has an outer square cross-sectional shape seen in a plane perpendicular to a longitudinal axis rod the upper strut 6. The plasterboard support (not shown) has a mounting bracket having an inner cross-sectional shape corresponding to the outer cross-sectional shape of the top end 9 of the upper strut 6, so that the plasterboard support may be mounted to the top end 9 of the upper strut 6. The top end 9 of the upper strut 6 may have other shapes than rectangular such as round. Also, the plasterboard support (not shown) may have a mounting bracket, instead of inner, having an outer cross-sectional shape corresponding to an inner cross-sectional shape of the top end 9 of the upper strut 6

The holder has a locking mechanism 10, which automatically locks the upper strut 6 in relation to the lower strut 5, when the upper strut 5 is in a desired position in relation to the lower strut 6, after having been raised or lowered in relation to the lower strut 5 by operating the hand-driven wheel 8. The holder also has a release mechanism 11 for releasing locking of the upper strut 5 in relation to the lower strut 6, when the upper strut 5 is to be raised or lowered to another position in relation to the lower strut 6.

Fig. 2A-2D show a sander support and parts of a sander support for supporting a so- called giraffe® sander (see Fig. 6). A giraffe® sander is a piece of equipment known to the person skilled in the art, and used for furbishing or refurbishing rooms of buildings, especially for sanding a ceiling, possibly a concrete ceiling to be painted or to be covered by a ceiling covering like felt, possibly also after mounting of plasterboards, in order to make the ceiling smooth before painting the ceiling or before applying a ceiling covering. The sander support has two support brackets 12,13 with cavities 14,15 each shaped as a V-shaped cradle. The cavities 14, 15 of each support bracket 12,13 are intended for supporting an elongate rod of the giraffe® sander (see Fig. 6). Each of the two support brackets 12,13 has flanges 16,17 extending outwards from the cavities 14,15. The flanges 16,17 are facing each other, and the flanges 16,17 have fastening elements for forcing the flanges towards each other, when the elongate rod of the giraffe® sander is supported in the cavities.

In the embodiment shown, the fastening elements are bolts 18 and nuts 19. The bolts 18 have hand knobs 20 and the bolts 18 extend through orifices 21 in flanges 16 of the one bracket 12. In the embodiment shown, the orifices 21 are open-ended slot with an inlet 22, so that the one bracket 12 may be slid into engagement with bolts (see below) of a fastening mechanism. The one bracket 12 is an upper support bracket, when the sander support is mounted to the top end 9 of the upper strut 6. The nuts 19 are provided at a bottom surface of the flanges 17 of the other support bracket 13. The other support bracket 13 is a lower bracket, when the sander support is mounted to the top end 9 of the upper strut 5. The hand knobs 20 are for operating the bolts 18 by hand, thereby threading the bolts 18 in or out of the nuts 19, and thereby forcing or releasing the two support brackets 12,13 towards each other or away from each other.

The sander support also has a mounting bracket 23 for mounting the sander support to the top end 9 of the upper strut 6. The mounting bracket 23 has an inner cross- sectional shape corresponding to the outer cross-sectional shape of the top end 9 of the upper strut 6. Thereby, when the sander support is mounted to the holder, the mounting bracket 23 extends along and around the top end 9 of the upper strut 6. In the embodiment shown, the mounting bracket 23 has a rectangular cross-sectional shape. Preferably, the inner cross-sectional shape of the mounting bracket 23 and the outer cross-sectional shape of the top end 9 of the upper strut 6 are square.

When the mounting bracket 23, and thereby the sander support, is mounted to the top end 9 of the upper strut 6, the sander support is prevented from rotating around a vertical axis in relation to the upper strut 6. This is an advantage, if the sander support is used together with a steering grip (see Fig. 3A-3C and Fig. 6).

If the mounting bracket and the top end of the upper strut have a square cross- sectional shape, the sander support may be mounted to the top end of the upper strut in either one of four different directions, each direction offset 90 degrees in relation to each other. The giraffe® sander, when supported by the sander support, may thereby extend with a sander disc (see Fig. 6) either to the one side in relation to the hand- operated wheel, or to the opposite side, or forwards or rearwards in relation to the hand-operated wheel. This is an advantage, because the extension of the sander disc to either one of the four extension may be shifted, depending on which extension of the giraffe® sander is the most efficient for the user and/or which extension of the giraffe® sander is ergonomically the most correct for the user. As example, the giraffe sander® may extend with the sander disc forwards making it easy for the user to visually follow displacement of the sander disc along the ceiling when sanding the ceiling.

Alternatively to the mounting bracket extending along and around the top end of the upper strut, the mounting bracket has an outer a cross-sectional shape corresponding to an inner cross-sectional shape of the top end of the upper strut, so that the mounting bracket extends along and inside the top end of the upper strut of the holder.

The mounting bracket 23 is fastened to the top end 9 of the upper strut 6 by a bolt 24 and a nut 25. The bolt 24 has a hand knob 26. The nut 25 is welded to the mounting bracket 23, and when the hand knob 26 is turned clock-wise, the bolt 24 is threaded into the nut 25 and through a hole (not shown) in the mounting bracket 23 and aligned with the nut 25. When the bolt 24 is threaded into the nut 25, a free end of the bolt 24 forces an outer surface (not shown) of the top end 9 of the upper strut 6 into frictional engagement with an inner surface (not shown) of mounting bracket 23. Thereby, the sander support is fastened to the top end 9 of the upper strut 6.

The sander support has a hinge 27 between the lower bracket 13 and upright extension 28 forming part of the mounting bracket 23. The hinge 27 allows the support brackets 13,14 to pivot around a longitudinal axis of the hinge 27, when the sander support is mounted to the top end 9 of the upper strut 6. The sander support pivoting around the hinge 27 results in the giraffe® sander, when supported in the support brackets 12,13, pivoting upwards and downwards. The giraffe® sander pivoting upwards and downwards results in the giraffe® sander adjusting, in relation to the height of the sander support, to a height and an inclination of a ceiling to be sanded. Pivoting the giraffe® sander to adjust to the height and inclination of the ceiling to be sanded is performed primarily by telescopic displacement of the upper strut 6 in relation to the lower strut 5, and secondly by pivoting the two support brackets 13,14 around the longitudinal axis of the hinge 27.

The sander support has a handle support 29 for a handle rod 30. In the embodiment shown, the handle support 29 is a piece of pipe welded to the lower bracket 14 of the sander support. One end 31 of a handle rod 30, constituting an aspect of the invention, is inserted upwards and into the handle support 29 and is fastened to the handle support 29. Another end 32 of the handle rod 30 extends downwards and opposite to the one end 31. The handle rod 30 is for adjusting the giraffe® sander (see Fig. 6) in relation to the holder, when the giraffe® sander is supported by the sander support. The handle rod 30 may be used for pivoting the lower strut 5 together with the upper strut 6 and the sander support around the vertical axis of the bearing 7 between the support strut 4 and the lower strut 5. The handle rod 30 may alternatively or additionally be used for pivoting the two support brackets 13,14 supporting the giraffe® sander around the longitudinal axis of the hinge 27. The handle rod 30 is fastened to the handle support 29 by a bolt 33 and a nut 34. The bolt has a hand knob 35. The nut 34 is welded to the handle support 29. When the hand knob 35 is turned clock-wise, the bolt 33 is threaded into the nut 34 and through a hole (not shown) in the handle support 29 and aligned with the nut 34. When the bolt 33 is threaded into the nut 34, a free end of the bolt 33 forces an outer surface (not shown) of the one end 31 of the handle rod 30 into frictional engagement with an inner surface (not shown) of the handle support 29. The handle rod 30 has the one end 31 being bent along one angle a in relation to the a middle section of the handle rod and the other end 32 being bent along another angle β in relation to the middle section. The one angle a is larger than the other angle β. Inserting the one end 31 of the handle rod 30 into the handle support 29 results in the handle rod 30 extending along one angle in relation to the handle support 29 and the sander support itself. Inserting the other end 32 of the handle rod 30 into the handle support 29 results in the handle rod extending along another angle in relation to the handle support 29 and the sander support itself. Thereby, the user may fasten the handle rod 30 to the sander support by inserting either the one end 31 or the other end 32 of the handle rod 30 into the handle support 29 of the sander support. Inserting the one end 31 or the other end 32 of the handle rod 30 into the handle support 29 of the sander support depends on which extension is the most comfortable for the user.

The sander support will often be used subsequently to having used a known plasterboard support (not shown). The plasterboard support is used together with the holder, when a ceiling cladding such as plasterboards is to be mounted to supporting struts of the ceiling. Subsequent to the ceiling cladding such as plasterboards is mounted, the ceiling cladding may need to be sanded. During sanding of the ceiling cladding such as plasterboards, the sander support of this aspect of the invention is advantageously used.

Fig 3A-3C shows a steering grip attached to the lower strut 5. The steering grip is used for steering the holder with any of the other tools being supported by the holder and according to aspects of the invention. The steering grip has a handlebar 36 for a user to grab when using the steering grip for steering the holder. The handlebar 36 is curved, thereby providing various comfortable positions for the user to grab the handlebar 36.

In the embodiment shown, the steering grip has covers 37 at an outer first grip end of the handlebar and at an outer second grip end of the handlebar, at positions where the user most likely will grab the handlebar 36. In the embodiment shown, the covers 37 are made of rubber. Alternatively, the handlebar 36 has no covers, or the handlebar 36 has one or more covers extending along the entire extension of the handlebar, so that the user have covers to grab at any suitable position along the handlebar 36. The covers may be made of another material than rubber such as another elastomer or and even other material also increasing friction between the user's hands and the handlebar, when the user grabs the handlebar, and also making the grab by the user's hands onto the handlebar more comfortable for the user.

The steering grip has a mounting bracket 38 capable of and intended for partly surrounding the lower strut 5 of the holder. In the embodiment shown, the mounting bracket 38 is U-shaped and has a width Wl between branches 39 of the U-shaped mounting bracket 38 being a little larger and corresponding to a width W2 of the lower strut 5 having a rectangular cross-sectional shape. The mounting bracket may have another shape than U-shaped in order to correspond to a cross-sectional shape of a upper strut of anther holder, such as a strut having a circular cross-sectional shape. The mounting bracket 38 has a fastening mechanism for fastening the mounting bracket 38 to the lower strut 5, when the mounting bracket 38 is positioned with the branches 39 around the lower strut 5. In the embodiment shown, the fastening mechanism are bolts 40 and nuts 41. Bolts 40 extend through holes (not shown) in the one branch 39 of the U-shaped mounting bracket 38. The opposite branch of the U-shaped mounting bracket 27 has nuts 41.

When the bolts 40 are inserted through the holes (not shown), and passes from the one branch to the other branch of the U-shaped mounting bracket 38, and is threaded into the nuts 41, the two opposite branches 39 will be forced towards each other. Forcing the two opposite branches 39 towards each other results in the two opposite branches 39 being forced towards the lower strut 5 and the two opposite branches 39 frictionally engaging the lower strut 5. Thereby, the steering grip is fastened to the lower strut 5. In the embodiment shown, the steering grip has a connection rod 42 being a piece of rod extending between the handlebar 36 and the mounting bracket 38. The connection rod 42 provides a distance D between the handlebar 36 and the mounting bracket 38, resulting in the handlebar 36 being situated at a distance D from the lower strut 5, when the steering grip is mounted to the upper strut 5. The distance D results in the user, when gripping the handle bar 36, not stumbling across the base legs 2 and the base wheels 3, when steering the holder by use of the steering grip.

A distance between the outermost positions of the first grip end and the second grip end proximately 850 mm. Other distances between the outermost positions of the first grip end and the second grip end may be provided, either a smaller or a longer distance, as long as the user gets a comfortable and ergonomically correct grip on the handlebar, so that steering of the holder, with sander support and the sander mounted to the holder, provides an easy, reliable and comfortable working condition for the user.

Fig 4A-4B show a roll support for supporting a roll of ceiling covering (not shown). Ceiling covering may be tapestry, felt or other rolled-up foil. Ceiling covering may be supported at a position just beneath the ceiling, when using the roll support mounted to the holder. The roll support has a hanger bar 43 extending along a first, upper horizontal rod 44, along an intermediate rod 45 and along a second, lower horizontal rod 46. The intermediate rod 45 connects the lower horizontal rod 46 with the upper horizontal rod 44. The intermediate rod 45 provides a spacing S between the upper horizontal rod 44 and the lower horizontal rod 46. The upper horizontal rod 44 is for supporting an inner core of a roll of ceiling covering used when furbishing or refurbishing rooms of a building.

The spacing S between the upper horizontal rod 44 and the lower horizontal rod 46 is for accommodating the radius of a part of the roll of ceiling covering extending beneath the upper horizontal bar 44, when the roll is supported by the upper horizontal bar 44. A radius of another part of ceiling covering extends above the upper horizontal bar 44, when the roll is supported by the upper horizontal bar 44. The upper horizontal rod 44 has an inner stop 47 and an outer stop 48. The inner stop 47 and the outer stop 48 prevents the roll of ceiling covering, when the roll of ceiling covering is supported by the upper horizontal rod 44, from sliding off the upper horizontal rod 44.

The lower horizontal rod 46 has a mounting bracket 49 for mounting the roll support at the top end 9 of the upper strut 6. The mounting bracket 49 has an inner cross- sectional shape corresponding to the outer cross-sectional shape of the top end 9 of the upper strut 6. Thereby, when the roll support is mounted to the top end 9 of the strut 5, the mounting bracket 49 extends along and around the top end 9 of the upper strut 6. The mounting bracket 49 has a cross-sectional area being rectangular.

Preferably, the inner cross-sectional shape of the mounting bracket 23 and the outer cross-sectional shape of the top end 9 of the upper strut 6 are square.

When the mounting bracket, and thereby the roll support, is mounted to the top end 9 of the upper strut 6, the roll support is prevented from rotating around a longitudinal axis along the upper strut 6. This is an advantage in that the roll itself and a free end of ceiling covering thereby extends in the one and same direction during dragging of an extension of ceiling covering and application of the ceiling covering to the ceiling.

If the mounting bracket and the top end of the upper strut have a square cross- sectional shape, the roll support may be mounted to the top end of the upper strut in either one of four different directions, each direction offset 90 degrees in relation to each other. The roll of ceiling covering, when supported by the roll support, may thereby extend with a free end of the roll of ceiling covering either to the one side in relation to the hand-operated wheel, or to the opposite side, or forwards or rearwards in relation to the hand-operated wheel. This is an advantage, because the extension of the free end to either one of the four extension may be shifted, depending on which extension is the most efficient for the user and/or which extension is ergonomically most correct for the user.

Alternatively to the mounting bracket extending along and around the top end of the upper strut, the mounting bracket has an outer a cross-sectional shape corresponding to an inner cross-sectional shape of the top end of the upper strut, so that the mounting bracket extends along and inside the top end of the upper strut of the holder.

Although not shown in the figures, the mounting bracket 49 of the roll support may be fastened to the top end 9 of the upper strut 6 by a bolt and a nut in the same manner as the mounting bracket 23 of the sander support (see Fig. 2A-2D) is fastened to the top end 9 of the upper strut 6. Accordingly, the description related to fastening the mounting bracket of sander support is incorporated into the description of the roll support. Accordingly, the bolt may have a hand knob. The nut may be welded to the mounting bracket 49, and when the hand knob is turned clock-wise, the bolt is threaded into the nut and through a hole in the mounting bracket 49 and aligned with the nut. When the bolt is threaded into the nut, a free end of the bolt forces an outer surface (not shown) of the top end 9 of the upper strut 6 into frictional engagement with an inner surface (not shown) of mounting bracket 49. Thereby, the roll support is fastened to the top end 9 of the upper strut 6.

In the embodiment shown, the mounting bracket 49 is provided with a support bracket 50 for a foil support (not shown). In the embodiment shown, the support bracket 50 is a piece of pipe welded to the mounting bracket 49 of the roll support and extending in along an oblique angle between a horizontal extension and a vertical extension. A foil support is for supporting the free extension of foil of the roll of ceiling covering, when the free extension is dragged by the user from the roll of ceiling covering.

The foil support may be bristles of a broom (not shown). A broom handle is inserted with the free end of the handle from above and downwards into the support bracket 50, and with the free end of the broom handle displaced downwards through the support bracket 50. The broom handle is positioned in the support bracket 50 so that broom bristles extend upwards, preferably at a horizontal level as the upper horizontal bar. Because of the oblique extension of the support bracket 50, the broom bristles will extend upwards at a horizontal distance between 100 mm and 1000 mm from the upper horizontal bar.

Part of the free extension of the foil, when dragged by the user from the roll of ceiling covering, will pass along the broom bristles and will be supported by the broom bristles. Support of part of the free extension of the roll by the broom bristles results in frictional engagement between the part of the free extension of the roll and the broom bristles. Frictional engagement reduces or even eliminates the free extension of the roll in un-rolling in an un-controlled manner of the user. Uncontrolled un-rolling of the free extension of the roll may result from a weight of the free extension of the roll itself dragging the rolled-up foil and thereby unrolling the foil from the roll of ceiling covering.

The foil support extending through the support bracket 50, such as a broom handle, is fastened to the support bracket 50 by bolts 51 and nuts 52. The bolts have a hand knob 53. The nuts 52 are welded to the support bracket 50. When the hand knobs 53 are turned clock-wise, the bolts 51 are threaded into the nuts 52 and through a hole (not shown) in the support bracket 50. When the bolts 51 are threaded into the nuts 52, the bolts 51 forces an outer surface (not shown) of the foil support, such as a broom handle, into frictional engagement with an inner surface (not shown) of the support bracket.

When a roll of ceiling covering is placed on the upper horizontal rod 44 and thereby supported by the roll support, a free extension of the foil may be dragged by a user to a required length. Thereby, a required length of the foil is rolled off the roll, said length of foil to be mounted on the ceiling without the user or another user supporting the roll. The holder with the roll support mounted to the top end 9 of the upper strut may be placed in one end of a room, and the user may drag the free extension of the roll of ceiling covering to the other end of the room and attach the free extension of the roll to the ceiling. Thereby, the user need not initially cut an adequate and estimated length of the roll and subsequently attach one end of the cut length to the ceiling, possible having cut too little or having cut too much to cover the extension of the ceiling. The roll support will often be used subsequent to having used the sander support (see Fig. 2A-2B). The sander support is used together with a giraffe sander, when a ceiling cladding such as plasterboards has been mounted to supporting struts of the ceiling. Subsequent to the ceiling cladding having been sanded, the ceiling cladding may need to have a ceiling covering like felt applied to the ceiling cladding. During application of ceiling covering, the roll support of this aspect of the invention is advantageously used.

Fig. 5A-5B show a support board mounted to the top end 9 of the upper strut 6. The support board has a mounting plate 54 and a first mounting bracket 55 and a second mounting bracket 56, each of the mounting brackets 55,56 fastened to the mounting plate 54. Fig. 5A shows the support board mounted to the top end 9 of the upper strut 6 by use of the first mounting bracket 55 and with the mounting plate 54 extending vertically. Fig. 5B show the support board mounted to the top end 9 of the upper strut 6 by use of the second mounting bracket 56 and with the mounting plate 54 extending horizontally.

Each of the mounting brackets 55,56 has an inner cross-sectional shape corresponding to the outer cross-sectional shape of the top end 9 of the upper strut 6. In the embodiment shown, the inner cross-sectional shape of each of the mounting brackets 55, 56 is rectangular, corresponding to the outer rectangular cross-sectional shape of the top end 9 of the upper strut 6. Each of the mounting brackets 55,56 enables the support board to be attached to, and detached from, the top end 9 of the upper strut 6. Depending on whether the first mounting bracket 55 or the second mounting bracket 56 is used for mounting the support board to the top end 9 of the upper strut 6, the mounting plate 54 will either extend vertically, as shown in Fig. 5A, or extend horizontally as shown in Fig. 5B. Depending on the equipment, which is supported by the support board, the mounting plate 54 may be mounted either vertically or horizontally.

If each of the mounting brackets and the top end of the upper strut have a square cross-sectional shape, the support board may be mounted by either the one or the other mounting bracket to the top end of the upper strut in either one of four different directions, each direction offset 90 degrees in relation to each other. The equipment, when supported by the support board, may thereby extend either to the one side in relation to the hand-operated wheel, or to the opposite side, or forwards or rearwards in relation to the hand-operated wheel. This is an advantage, because the extension of the equipment to either one of the four extension may be shifted, depending on which extension of the equipment is the most efficient for the user and/or which extension of the equipment is economically the most correct for the user. Alternatively to the mounting bracket extending along and around the top end of the upper strut, the mounting bracket has an outer a cross-sectional shape corresponding to an inner cross-sectional shape of the top end of the upper strut, so that the mounting bracket extends along and inside the top end of the upper strut of the holder.

Although not shown in the figures, each of the mounting brackets 55,56 of the support board may be fastened to the top end 9 of the upper strut 6 by a bolt and a nut in the same manner as the mounting bracket 23 of the sander support (See Fig. 2A-2D) is fastened to the top end 9 of the upper strut 6. Accordingly, the description related to fastening the mounting bracket of sander support is incorporated into the description of the support board. Accordingly, the bolt of each mounting bracket 55,56 may have a hand knob. The nut of each mounting bracket 55,56 may be welded to the mounting bracket 55,56, and when the hand knob is turned clock-wise, the bolt is threaded into the nut and through a hole in the mounting bracket 55,56 and aligned with the nut. When the bolt is threaded into the nut, a free end of the bolt forces an outer surface (not shown) of the top end 9 of the upper strut 6 into frictional engagement with an inner surface (not shown) of mounting bracket 55,56. Thereby, the support board is fastened to the top end 9 of the upper strut 6, with the mounting board 54 extending horizontally or vertically.

The mounting plate 54 has holes 57 at different positions. Some holes are circular with a selected diameter, other holes are oblong with a selected shape, width and length. The position of the holes and the shape, diameter, width and length of the holes may be selected based on different uses and for different equipment for furbishing or refurbishing rooms of buildings, and possibly used in a sequence after each other.

The mounting plate and the mounting brackets of the support board are preferably all made of metal. Alternatively, the mounting plate may be made of wood or plastic. If the mounting plate is made of wood or plastic, a user of the holder may provide more holes himself or herself, than if the mounting plate is made of metal, or a user may more easily provide other holes additional to holes already made in the mounting plate. Also in the alternative, also the mounting brackets may be made of plastic or other material having a sufficient rigidity for mounting and maintaining the support board, and any equipment supported by the support board, to the top end 9 of the upper strut 6.

Fig. 6 shows a giraffe® sander supported by the sander support of the invention, and with a steering grip of the invention mounted to the holder. The giraffe® sander has one distal end 58 with an electromotor and another distal end 59 with the sander disc. In-between the distal ends, an elongate rod 60 is provided. The elongate rod of the giraffe® sander is for the sander disc to be able to reach a ceiling of a room, when the giraffe® sander is operated by a user standing on the floor of the room.

In known operation of the giraffe® sander, the one distal end and the elongate rod of the giraffe® sander is gripped by hands of the user. The user forces the other distal end with the sander disc towards the ceiling and maintains forcing of the sander disc towards the ceiling during sanding of the ceiling. This operation is very cumbersome and tiring to the user and requires a user with a certain amount of muscle force, which, e.g., women or elderly users may not have.

The sander support of the invention, and in combination with the steering grip of the invention, result in the user being able to sand ceilings by supporting the giraffe® sander in the sander support. Weight of the giraffe® sander may be selectively distributed on each side of the sander support, so that by just gripping the handlebar of the steering grip and steering the holder along the floor, the ceiling may be sanded correctly. Because of selected distribution of the giraffe® sander on each side of the sander support, especially with the somewhat heavy electromotor at the side of the sander support towards the one distal end 58, gravity may force downwards the part of the giraffe® sander extending on the side of the sander support toward the one distal end 58. The giraffe® sander will pivot around the horizontal hinge (see Fig. 2A- 2D) and the other distal end 59 with the sander disc will be forced upwards towards the ceiling.

Thereby, the user will be able to sand an entire ceiling by only operating the steering grip. Operating the steering grip eliminates the need for the user to handle manually the giraffe® sander itself. Operating the steering grip maintains the hands and shoulders of the user in a position being more comfortable and being economically more correct to the user. The user will be able to sand ceilings faster during a working day and/or the user will be able to sand more ceilings or sand more of one ceiling during a working day.
