Description

System for preventing a person to fall from a roof of a building and method for providing such a system
The invention relates to systems for preventing a person to 5 fall from a roof of a building.
As any other part of a building, the roof of a building needs maintenance from time to time, and systems are provided for preventing that persons carrying out said 10 maintenance fall from said roof. The invention in particular relates to such systems for substantially flat (parts of) roofs .
In a first embodiment of the invention said system comprises 15 a rail system with a rail which extends on said roof substantially parallel to and at a distance from an edge of said roof, to which rail a line can be secured which line can be secured at its other end to said person. Such systems are well known, for instance as described in European patent 20 application EP 1818480. The line can be secured to the rail by a traveller which can travel along the rail, such that the person is able to move along the edge of the roof, without the risk of falling from the roof.
25 In a second embodiment of the invention said system comprises a fence system with a fence which extends on said roof substantially parallel to an edge of said roof. Such systems are also well known, for instance as described in international patent application WO 2008/121843. The person 30 can safely work behind the fence without the risk of falling from the roof.
2
It is a goal of the invention to provide improved systems for preventing a person to fall from a roof of a building, which are safe to use, which are easy to use, which are simple, which are easy to install, which offer protection 5 during installation, which offer different protection levels, which expected to do little harm to the roof construction and/or roof characteristics and/or which can be easily reused.
10 According to one aspect of the invention said rail system comprises a multitude of tiles which are arranged on said roof in a linear array, wherein each of said tiles is provided with a rail connector, and wherein said rail is attached to each of said rail connectors. The word tile must 15 be interpreted as including any suitably shaped element, such as a slab, a filled container or other weight element. Preferably said rail connector comprises a band shaped element which fits around the tile such that the upper and lower sides of said band shaped element extend in the 20 longitudinal direction of said array of tiles. Said band shaped element is preferably pre-shaped to fit around said tile. By interconnecting the tiles in this manner by the rail, they form a large ballast, thereby securing the person on the roof. The rail connectors are easy to attach to the 25 tiles, and the rail can be easily attached to the rail connectors to form the array of interconnected tiles with said rail.
Similarly, according to the invention said fence system 30 comprises a multitude of tiles which are arranged on said roof, wherein each of said tiles is provided with a fence connector, and wherein said fence is attached to each of 3 said fence connectors, and wherein said fence connector comprises a band shaped element which fits around the tile.
Preferably said rail extends on top of the centre line of 5 said array of tiles. Thereby the tiles form a footpath on said roof, on which the person can walk with one foot on each side of the rail.
Said rail is preferably comprised of two parallel rows of 10 multitudes of strips or bars, which are arranged in an overlapping manner along said array of tiles. Thereby a very strong interconnection of the tiles can be obtained. Said strips or bars of said two parallel rows are preferably interconnected at least near the ends of the array of tiles 15 with said rail, such that they are prevented from mutually moving in the longitudinal direction. Preferably said rail is comprised of two parallel rows of strips, wherein the strips of each row extend in a horizontal orientation, and said two rows extend on top of each other.
20
The upper side of said rail connector is preferably provided with a connector element which is arranged to hold said rail. Said connector element is preferably substantially tube shaped and extending in the longitudinal direction of 25 said array of tiles, wherein each tube shaped connector element has a through hole having a cross section corresponding to the cross section of the strips or bars, such that said strips or bars can subsequently be inserted in through holes of connectors of neighbouring rail 30 connectors. Preferably said connector element is provided with two separate through holes, one for each row of strips or bars. This provides for easy installation of the rail system.
4
Said rail system preferably comprises spacers extending under said tiles for providing a space between the lower side of said tile and the upper surface of the roof, said 5 spacers being fixed against said tile by said rail connector, in particular said band shaped element. The spacers provide room under the tile for rain water to flow under it, and additionally temporary fence or marker elements can be easily fixed to said rail system, as will be 10 described later with reference to the preferred embodiments. Preferably each tile is provided with two spacers, one near each outer end in the longitudinal direction. Said spacers are preferably substantially strip shaped extending along the edges of said tiles, and are provided with a central 15 recess at their lower sides for accommodating said band shaped element. Said spacers are further preferably provided with means for preventing said tiles from moving in lateral direction and with connection means for connecting two spacers under neighbouring tiles in said array.
20
Said strips or bars preferably are made of metal, and said rail connectors are preferably substantially made of plastic.
25 In said fence system said fence is preferably hingeably attached to said fence connectors, such that said fence can be rotated from an upright position to a position wherein it extends in a substantially horizontal orientation.
Preferably said fence system comprises spacers extending 30 under said tiles for providing a space between the lower side of said tile and the upper surface of the roof, said spacers being fixed against said tile by said band shaped element. Said fence system preferably comprises a multitude 5 of second tiles which are each arranged on said roof adjacent one of said first tiles and extending on said roof in a direction perpendicular to said fence, each of said second tiles comprising a second band shaped element which 5 fits around the tile and wherein said first and second band shaped elements are connected to each other.
The invention also relates to a method for providing a system for preventing a person to fall from a roof of a 10 building, said system comprising a rail system with a rail which extends on said roof substantially parallel to and at a distance from an edge of said roof, to which rail a line can be secured which line can be secured at its other end to said person, 15 wherein said rail system comprises a multitude of tiles which are arranged on said roof in a linear array, wherein each of said tiles is provided with a rail connector, and wherein said rail is attached to each of said rail connectors, said method comprising the following sequence of 20 steps: said rail connectors are attached to said tiles; said tiles with said rail connectors are arranged on said roof in a linear array; and said rail is connected to said rail connectors.
25
The invention will be illustrated by means of preferred embodiments as shown in the drawings, wherein:
Figure 1 is a perspective view of a preferred embodiment of 30 the rail system of the invention;
Figure 2, 3A, 3B, 4, 5, 9A and 9B are perspective views of details of the rail system of figure 1; 6
Figure 6 is a perspective view of a preferred embodiment of a fence system in accordance with the invention; and 5 Figure 7 and 8 are perspective views of details of the fence system of figure 6.
According to figure 1 the flat roof 1 of a building is provided with a system for preventing a person 2 to fall 10 from the roof 1. The system comprises a rail system 3 with a rail 4 and a line 5 to which the person 2 is secured. The end of the line 5 is attached to the rail 4 by means of a traveller 6 which can run over said rail 4. The rail system 3 is mainly comprised of tiles 7, spacers 10, rail 15 connectors 8, and strips 9 forming said rail 4.
The tiles 7 with the rail connectors 8 are arranged in linear arrays along the edges of the roof 1, at a distance of a few meters thereof, and the strips 9 extend through the 20 rail connectors 8 to form said rail 4. In the corners of the rail system a corner rail piece 41 is mounted on the outer ends of the respective rails 4, such that the traveller 6 can run around the corner from one rail 4 to the next rail 4.
25
In an alternative use of the rail system 3, a temporary fence or marker can be installed by inserting the horizontal base 111 of uprights 11 into the space under the tiles 7 provided by the spacers 10, as shown in more detail in 30 figure 2, and providing a marker tape 12 between the uprights 11. Persons can work safely on the roof 1 inside the marked area.
7
The rail connectors 8 comprise a substantially band shaped part 81 which is pre-shaped in rectangular form with a closed circumference such that it fits around the cross section of the tiles 7. On the inside the part 81 is provide 5 with small spacers 82, such that the part 81 can be easily shoved towards the centre of the tiles 7. Before the part 81 is mounted on the tile, two spacers 10 are placed inside the part 81, with the lower sides of the spacers 10 against the lower side of the part 81 and against the two outer ends of 10 the part 81. The spacers 10 are provided with cavities 101 in the centre at their lower sides, which fit around the lower side of the part 81, such that lateral movement of the spacers 10 is prevented.
15 The spacers 10 are further provided with upright walls 102 near the two corresponding corners of the tile 7, such that the tile 7 will be constrained by the spacers 10 against lateral movement. Furthermore, as shown in figure 4 the spacers 10 are provided with slots 103 in said upright walls 20 102 near two corresponding corners of the tile 7, said slots extending vertically from the lower end of said walls 102, and cavities 104 behind said slots 103 with an opening in the bottom of the spacer 10. Connecting pieces 105 comprise a central plate shaped part 106 and two cylindrical enlarged 25 part 107 at both ends. The plate shaped part 106 of connecting pieces 105 can be inserted in two adjacent slots 103 of adjacent spacers 10 such that the cylindrical enlarged parts 107 are accommodated in the cavities 104 behind said slots 103 and the two adjacent spacers 10 are 30 connected to each other thereby. The connecting part 105 is provided with a flexible elastic securing lip which extends from its upper side in outward direction. Before the connecting part 105 is inserted in the cavities 104 the lip 8 108 is bent inwardly. Once the lip passes the upper end of the cavity 104 it will bend outwardly again and thereby prevent that the connecting piece falls out of the cavities 104 .
5
Connectors 8 are provided with substantially tube shaped connector elements 83 which extend above and are connected to the upper part of the band shaped element 81. Each connector element 83 has two through holes 84, 85, in which 10 the strips 9 fit. Once the tiles 7 with the connectors 8 and the spacers 10 are connected to each other and placed in an array on the roof 1, the first and second through holes 84, 85 are aligned with the first and second through holes 84, 85 of all the other connector elements in said array.
15
Strips 9, which may each be several meters long, are then inserted in said aligned through holes 84, 85, such that they extend on top of each other in horizontal orientation. The strips in the upper through holes 84 and the lower 20 through holes 85 are arranged such that the top strips 9 overlap with the bottom strips 9 along approximately half their lengths. Thereby a firm interconnection between the tiles 7 in the array is achieved, even without further fixation. At least near the outer ends of the array the top 25 strip 9 and the bottom strip 9 are connected to each other by means of a bolt 91 and nut 92 as shown in figures 3A and 3B, wherein the nut 92 is located between the two strips 9 acting as a spacer and in that position it will never fall from the bolt 91. It shows immediately that when the nut 92 30 and the bolt 91 are not firmly tightened, this will block the traveller 6. Accidental rotation of the bolt 91 as installed in corner rail piece 41 is prevented by a polygonal protrusion under the head of the bolt 91 which 9 fits in a corresponding polygonal cavity in the corner rail piece 41.
Furthermore spacer elements 93 are provided between the top 5 and bottom strips 9 between two tiles 7.
As shown in figure 5, fitting pieces 13 of various sizes are provided, so that the length of the array of tiles 7 can be matched against the roof size. Also bridge pieces 14 are 10 provided for allowing the unhindered crossing of cables for instance .
Figures 9A and 9B show the traveller 6, comprising a gripping element 61 having a substantially C-shaped cross 15 section, such that it fits loosely around the rail 4, such that it can travel along said rail, but cannot be detached from it other than at outer ends of the rail 4. The gripping element 61 is comprised of a substantially C-shaped metal outer shell 62, and a plastic inner shell 63 with rounded 20 corners, which inner shell 63 is an element that supports, guides and reduces the friction of motion between rail 4 and traveller 6. On top of the gripping element 61 an eye ring 64 is provided, for connecting the line 5 by means of a hook 51.
25
According to figure 6, 7 and 8 the flat roof 1 of a building is provided with another system for preventing a person to fall from the roof 1. The system comprises a fence system 3'. The fence system 3' is mainly comprised of tiles 7, 30 spacers 10, fence connectors 8', and a fence 4'. Tiles 7 and spacers 10 are identical as described with reference to figures 1-5. The fence connectors 8' comprise band shaped elements 81' which are similar to band shaped elements 81, 10 except that they are made from metal and do not form a closed circumference. Instead, they have upright bent parts 83' at their outer ends on top of the centre of the tiles 7, which upright bent parts 83' are fixed to the uprights 41' 5 of the fence 4' extending between said upright bent parts 83' by means of bolts and nuts, so that the fence is firmly fixed against the tiles 7.
As shown in figure 8 a second tile 7 with spacers 10 and 10 band shaped element 81' is connected to the adjacent first tile 7 holding the upright 41' of the fence 4', by means of a beam 84' extending between and fixed to the upright bent parts 83' of the band shaped elements 81' of both tiles 7. These second tiles 7 form ballast weights preventing the 15 fence from falling over the edge of the roof 1. The fence 4' is connected to the band shaped elements 81' in such a way that the fence can be rotated inwardly from the upright position towards the roof surface when it's not in use, but such that it is blocked against rotation from the upright 20 position outwardly.
While the above provides a full and complete disclosure of the preferred embodiments of the present invention, various modifications, alternate constructions and equivalents may 25 be employed without departing from the true spirit and scope of the invention. Therefore, the above description and illustration should not be construed as limiting the scope of the invention.
