- the dimensions of a base before it is assembled in the place of destination result in a need for a certain space in means of transport to deliver a base to a construction site, where the internal space of a base is an empty space to a large extent.
- the solution to this problem is the development of a folding base of flat parts which do not contain empty spaces.
- a base is assembled by connecting previously prepared parts using screws, which is labour-intensive, especially in the case of roofs of industrial or commercial facilities with a huge number of such roof units.
- individual parts are assembled by putting hooks of some parts into slots formed in other parts.
- the purpose of the invention is to develop a base structure for roof units, in particular such units as roof hatches, skylights, smoke vents and ventilation flaps, as a folding base, which is easy and quick to assemble, and at the same time characterised by a rigid structure, without clearance in connections of individual parts and enabling quick and easy elimination of clearance, if any.

- Each projection has the form of a flat being an extension of the surface of the side wall.
- Each projection is bent along a line parallel to the edge of the side wall at an acute angle outwards of the base.
- the projections described above with a comb-like arrangement on each side edge of the base side wall are separated from one another by spaces.
- a row of comb-like projections on one side edge of the side wall is moved in relation to a row of comb-like projections on another side edge of the side wall, so that after putting two perpendicular side walls together, in the areas of spaces on the edge of one side wall in the assembled base the comb-like arranged projections of another side wall are arranged.

- roof units such as windows, smoke vents, air vents and smoke vent flaps
- the comb-like projections of one side wall enter into spaces between the same projections of the adjacent perpendicular side wall.
- the comb-like projections are formed so that the meshed projections of adjacent walls form a fully rigid vertical connection, very easy to be assembled on the roof.

- a connection is achieved by simple inserting the connecting pin, which is a very simple activity to perform during the assembly process of such a base.
- the solution according to the invention has proved to be particularly advantageous in work performed on the roof. When all the side walls are connected, the final rigidity of the base structure is obtained by fixing parts of the bottom flange to the roof surface.

EP 2351893 discloses a rectangular shaped base comprising a top base element and a bottom element. The base is a kind of an upstand with a central through opening between four slanting side walls on a rectangular plan and is based on the edges of a roof opening. An upper rim of the base is intended for mounting a window or a roof hatch thereon. According to this known solution the base is a folding structure. Each of the four substantially vertical corner angles comprises two hooks near each of the vertical edges. On each two corner angles, on said hooks a side wall is mounted, which in appropriate places comprises slots for fixing the side wall on the hooks of the corner angles. In this way the four base walls are mounted on the hooks of the corner angles, and then the whole is topped by the upper rim which stabilises the folded base. - Another European patent application No.
EP 0967345 discloses another solution of a base for skylights, ventilation system units and any roof units. The base is preferably made of fibreglass with the aim to avoid the stagnation of rain water around a skylight. Said base creates a continuous surface of the insulating cover. - Another solution known from US patent specification No.
US 5687514 discloses another solution of a curb for encasing openings for units mounted on a roof. The curb has a rectangular box structure, delimited by four side walls. Each side wall in an upper part is bent outwards forming on the upper edge of the curb a flange to which an external unit in the form of a smoke vent window and other roof units can be mounted. The connected side walls using pre-drilled holes are mounted on a bottom flange. In this known solution, the curb is folding and is connected by means of screws using corner angles. - According to utility model description
DE 20 2006 000881 , a base comprises side walls each having integral fixing elements for fixing a neighboring side wall. The side walls are made from bendable sheet metal. The side walls have slots on the edge side into which a protruding clip from a neighboring side wall is inserted. Each side wall has a base flange with angled wall sections and an upper edge section. - According to patent description
US 6041557 the four metal panel portions of an air conditioning unit roof curb have spaced sets of inwardly projecting lanced portions positioned adjacent their ends and defining tab-receiving slots. With the panel portions in a rectangular assembly orientation, specially designed drive cleats are used to lock the contiguous ends of the panel portions together at the corners of the curb. - Other bases for roof units are known from
US 5148647 andUS 3802131 . - The invention solves the problem of reducing the dimensions of a base during its transport. The dimensions of a base before it is assembled in the place of destination result in a need for a certain space in means of transport to deliver a base to a construction site, where the internal space of a base is an empty space to a large extent. The solution to this problem is the development of a folding base of flat parts which do not contain empty spaces. In prior art solutions a base is assembled by connecting previously prepared parts using screws, which is labour-intensive, especially in the case of roofs of industrial or commercial facilities with a huge number of such roof units. However, in other known solutions of a folding base, individual parts are assembled by putting hooks of some parts into slots formed in other parts. This type of connections using hooks in slots are characterised by certain clearance in these connections, because making a slot in one part with exactly the same width as the thickness of an interacting hook will make it impossible to put such a hook into this slot. To make this possible, it is necessary to design a slot which is slightly wider than the thickness of a hook. However, after putting a hook into such a slot, there is a certain degree of clearance in such a connection. As a result of wind gusts from different directions this natural clearance in connections of parts of a base, in particular in roof units, can be greater over time. These effects can be eliminated but this requires additional treatments.
- The purpose of the invention is to develop a base structure for roof units, in particular such units as roof hatches, skylights, smoke vents and ventilation flaps, as a folding base, which is easy and quick to assemble, and at the same time characterised by a rigid structure, without clearance in connections of individual parts and enabling quick and easy elimination of clearance, if any. This task has been solved by the development of the folding base structure according to
claim 1 and the subsequent claims. - According to the invention, the folding base, in particular for window roof units and ventilation and fire protection units has the form of side walls and connecting members. Each side wall comprises an upper and bottom edge and two side edges with connecting members. The side walls comprise portions of a bottom flange fixing the base to the roof and portions of an upper flange to which a roof unit is attached.
- The folding base according to the invention is characterised by the features of
claim 1, in particular in that the side edges of the adjacent side walls comprise rows of projections. Each projection has the form of a flat being an extension of the surface of the side wall. Each projection is bent along a line parallel to the edge of the side wall at an acute angle outwards of the base. The projections described above with a comb-like arrangement on each side edge of the base side wall are separated from one another by spaces. A row of comb-like projections on one side edge of the side wall is moved in relation to a row of comb-like projections on another side edge of the side wall, so that after putting two perpendicular side walls together, in the areas of spaces on the edge of one side wall in the assembled base the comb-like arranged projections of another side wall are arranged. In this patent specification, the side edge of the side wall should be understood as a common line determined by the spaces between the comb-like arranged projections. - The bent sections of the projections of two combined at a right angle, adjacent side walls of the base, in a view consistent with the direction of the connection edge of the two walls preferably form a semi-enclosed section.
- The projections are preferably bent along the lines parallel to the side edges determined by the projections on the side edge of the side wall.
- Inside the semi-enclosed section between the bent projections along the entire length of contact of the side edges of two side walls, there is an inserted pin, parallel to the contact, with a section corresponding to the form of the semi-enclosed section.
- The semi-enclosed section preferably has the shape of a triangle, and the pin has the form of an angle whose arms correspond to the length of the arms of the triangle of the semi-enclosed section.
- According to the invention, the base is proposed for roof units, such as windows, smoke vents, air vents and smoke vent flaps, assembled of side walls which contain on edges a system of comb-like connecting projections. In two side edges of adjacent side walls, the comb-like projections of one side wall enter into spaces between the same projections of the adjacent perpendicular side wall. The comb-like projections are formed so that the meshed projections of adjacent walls form a fully rigid vertical connection, very easy to be assembled on the roof. The vertical rigidity in this solution is achieved by inserting a connecting member in the form a pin into a chamber formed by the projections of one side wall alternately arranged one under the other and the projections of the adjacent side wall. The shape of the connecting pin is matched to the shape of the internal chamber which is created in a view corresponding to the direction of the chamber by the bent projections put between one another of two adjacent side walls. A connection is achieved by simple inserting the connecting pin, which is a very simple activity to perform during the assembly process of such a base. The solution according to the invention has proved to be particularly advantageous in work performed on the roof. When all the side walls are connected, the final rigidity of the base structure is obtained by fixing parts of the bottom flange to the roof surface. Since usually a lot of this kind of bases for roof units are installed on large industrial or commercial facilities, the issues of transport of often a huge number of bases to a construction site are important. The solution according to the invention has greatly enabled the reduction of the volume of the flat base according to the invention, before assembly on the roof, in transport operations.

side wall side walls Fig. 1 shows fixed to the upper flange 6 hinges 14 to which, for example, a smoke vent can be fixed, as shown inFig. 8 . This type of a vent or a roof window is usually fitted with a mechanism for remote closing and opening, which is, however, not shown here, because it is not the subject of the invention. -

In other embodiments the number of projections on the edges of the side walls can be different. -
Fig. 3 and Fig. 4 show that eachprojection 8 has the form of a flat being an extension of the surface of theside wall projection 8 is bent along abending line 9 parallel to the edge of theside wall projection 8 is bent from the inside of the base to the outside. - The comb-like arranged, one in a certain distance from the other,
projections 8 on each side edge of theside wall spaces 10. A row of the comb-like projections 8 on one side edge of theside wall 1 is moved in relation to a row of the comb-like projections 8 on another side edge of theside wall 1. In the areas of thespaces 10 on the edge of oneside wall 1 in the assembled base the comb-like arrangedprojections 8 of anotherside wall 2 of the base are arranged. In this patent specification, the side edge of theside wall spaces 10 between the comb-like arrangedprojections 8. Each of theside walls like projections 8 but moved on one side edge in relation to the other side edge of theside wall side walls projections 8 of one side wall take the place of the comb-like arrangedprojections 8 of the other side wall. Theprojections 8 are preferably bent along thebending lines 9 parallel to the side edges determined by theprojections 10 on the side edges of thewalls Fig. 5 shows that theprojections 8 of thewall 1 are bent along the bendingedge 9 at an angle of 45°. This figure schematically shows stiffening embossments of theside wall 1 in this embodiment. - An example of a connection of the
side walls Fig. 7 in a view consistent with the direction of the resulting connection. As it is shown in this figure, theprojections 8 of theside walls semi-enclosed section 11 in the form of a triangle. In a view as inFig. 7 , the section seems to be closed. Thesemi-enclosed section 11 has the shape of an equilateral triangle. A connector in the form of apin 12 is inserted into thesemi-enclosed section 11. Thesame pin 12 is shown inFig. 4 before being inserted between theprojections 8 of theadjacent walls pin 12 has the length corresponding to the height of connections of theside walls pin 12 has the form of an angle with an angle of 90°, whose width of arms corresponds to the length of the catheti of said triangle of thesemi-enclosed section 11. When thepin 12 is inserted, theparticular projections 8 may be individually subjected to the pressure of thepin 12 which contributes to the resulting rigidity of the edge of each connection of two perpendicular side walls of the base. Where some of theprojections 8 protrude from thepin 12, these projections can be simply struck with a hammer to thepin 12, which in working conditions on the roof is not a complicated activity. -
Fig. 8 shows the assembled base according to the invention with asmoke vent 13 which is in this figure an example of a roof unit mounted on the base according to the invention. -
