FR2514055A1 - Electrically operated roof opening system e.g. for sports halls - uses four independent roof panels sliding longitudinally when electric motors drive rack gear on each panel - Google Patents

Abstract

The system is intended for sports halls or agricultural buildings with wooden or metallic roof beams. Four roof panels are free to move longitudinally on rails fixed to the walls of the building near the eaves and near the peak of the roof. Each panel is independent of the others, allowing various combinations of part-open and part-closed. The roof panels are fitted with a rack gear, mounted on an internal surface. An electric motor with a pinion gear on its output shaft is fixed onto the roof frame, and the pinion meshes with the rack. When the motor is energised the roof panels move in accord with the direction of rotation of the motor.

Description

 The present invention relates to a system for opening the curtains of buildings for sporting and agricultural uses by moving four mobile roof panels, independent of each other, making it possible to discover up to 50 ffi of the surface area of the playing fields , culture or storage.

 Among the existing processes, there are proposed - electrically discoverable structures with a light metal frame along which slides a coated canvas P.V.C which is stored, folded up, at each end of the field. The disadvantage of this structure is the lack of resistance of the assembly to weathering and the canvas, in particular, which by dint of being folded, deteriorates.

- fully removable removable canvas structures. This process does not cover or quickly discover the terrain in time ionction. On the other hand, this form of structure exhibits a very significant condensation phenomenon during the dry and humid periods.

- telescopic structures that can be opened electrically by sliding on rails of the load-bearing metal frame, the elements of which stem from one another. This heavy process proc is very delicate to implement and, consequently, of a very raised cost.

- structures with uncoverable roofs (in polyester or steel trays), the side panels of which open by sliding on a rod (for canvas panels) or on rails (for steel or polyester panels). This process has the major drawback of creating large air currents when there is wind, on the other hand, ventilation is insufficient in summer in the absence of wind.

 The proposed opening system avoids all these drawbacks. In addition, the electrically discoverable systems are mounted on a metal frame only, while the proposed process is mounted on a glue-laminated wooden frame whose aesthetics and fire resistance are much better than metal.

 The opening roof is made up of four mobile central panels independent of each other and representing 50 ffi of the area of the land to be covered. These movable panels are mounted on rails and moved by a central rack fixed in the thickness of the panel inside of it. The rack is actuated by an electric motor fixed on the frame so that the mechanism is protected by the movable panel.

 The movable panels slide longitudinally and come to be superimposed on the fixed parts of the roof, thus freeing 50 ffi from the area of the ground initially covered.

 Fixed side panels with a height of 3 meters eliminate the inconvenience of wind and therefore drafts. The possibility of having transparent (side) panels only increases the pleasure of this structure mainly in the application for sports halls.

 The mobile panels being independent of each other, all the possibilities of opening are achievable according to the force of the wind or the position of the sun.

 The accompanying drawings correspond to top views in the closed (Fig. 1), open (Fig. 2) and mixed (Fig. 3) positions as well as a profile view in the open position (Fig. 4) and a section showing the position of the movable panels, the guide rails and the drive system with respect to the frame (Fig. 5).

 FIG. I represents the structure in the closed position, the 4 mobile panels 1-2-3-4 being attached to the center of the frame, the parts of fixed roofs being represented in 5 and 6.

 FIG. 2 represents the complete opening of the roof, the mobile panels 1-2-3-4 having slipped and covered the fixed parts revealing the zone 7.

 Figure 3 shows a possibility of partial opening.

Only the movable panels 1 and 2 are open, the 3 and 4 remain closed in order to protect from the sun or strong wind. The surface 7 discovered is nevertheless sufficient to allow good ventilation.

 Figure 4 shows a side view of the open structure.

The fixed side panels 8-9 (possibly transparent) with a height of 3 meters offer good wind protection.

FIG. 5 shows the device for driving the mobile panels by rack 1 and electric motor with pinion 2 as well as
(4) their positioning in relation to the frame as well as the location of the guide rails 3.

 This structure, which can be discovered easily and quickly, makes it possible to practice the sport in all weathers, therefore making the facilities profitable.

 In addition, mounted on a metal frame, this innovation can be used in the agricultural sector for the construction of greenhouses (importance of the independence of mobile panels) or buildings for storing and drying certain products.
