BRIEF description of the drawings
The invention will be elucidated on the basis of an exemplary embodiment shown in the attached drawings, in 5 which:
Figure 1 is an isometric view of a greenhouse with a roof having ventilation windows with a netting system according to an embodiment of the invention;
figures 2A and 2B are isometric views, one with a 10 partial cut-out, of one of the ventilation windows with the netting system of figure 1; and figure 3 is a cross section the ventilation window with the netting system as shown in figures 2A and 2B.
DETAILED DESCRIPTION OF THE INVENTION
Figures 1, 2A and 2B show a greenhouse 1 of the 20 Venlo type. The greenhouse 1 comprises a roof construction 10 that is supported by multiple parallel rows of vertical columns 11. The roof construction 10 comprises multiple parallel roof ridge profiles 15 and lower rain gutter profiles 18 that are interconnected with slanting window 25 profiles 16. The profiles 15, 16, 18 form rectangular rabbets for fixed glass panels 20 that for the slanting upper surface of the roof construction.
The roof construction 10 furthermore comprises regularly distributed ventilation windows 30 that at the 3 0 upper side are hingeably connected with the roof ridge profiles 15. As shown in figures 2A and 2B the ventilation windows 30 are in this example shorter than the fixed glass panels 20. Therefore a horizontal window profile 17 is mounted between the two adjacent slanting window profiles 16 35 of each ventilation window 30 to form a rabbet for an additional fixed glass panel. 21 below the ventilation window 20. The roof ridge profiles 15, the slanting window profiles and the horizontal window profiles 17 together form first frameworks that define roof openings in the roof construction 10. The profiles 15, 16, 17, 18 are made of metal, in particular aluminum.
The ventilation windows 30 comprise a translucent glass panel 31 and a second framework 32 along the free edges of the glass panel 31. The glass panel 31 is transparent to allow light to enter the greenhouse 1. In this example the glass panel 31 is of hardened glass, whereby the glass panel 31 has sufficient strength to carry its own weight and sufficient stiffness to remain in it shape without the need for a rigid framework around its entire circumference. Alternatively a plastic panel is applied, such as a polycarbonate panel. In this example the second framework 32 has a front profile 33 along the free distal edge of the glass panel 31, and two side profiles 34 along the parallel side edges of the glass panel 31.
Each ventilation window 30 can swing around its hinge axis A in direction B between the open position as shown in figure 2, and a closed position to regulate the ventilation of the greenhouse 1. In the closed position the second framework 32 rests on the window profiles 16, 17. The ventilation windows 30 are swung in direction B by in this example two push rods 40 having distributed connections 41 in the hardened glass panels 30 and a common connection with a slide 42 that can move in direction C along a horizontal rail 43 of the roof construction 10 by means of an e1e ct romoto r.
The ventilation 'windows 30 are each provided with a netting system 50 to prevent passage of insects when the ventilation windows 30 are in the open position. These can be harmrul insects that have to be kept outside the greenhouse 1 or specific insects that are held inside the greenhouse 1. The netting system 50 comprises an insect netting 51 of fine mesh plastic gauze 52 that extends in the ventilation passage between the roof construction 10 and the ventilation window 30. The insect netting 51 is pleated in a bellow configuration in order to stack when it collapses. At the upper side the insect netting 51 is connected with the second framework 32, for example by stitching, and at the lower side the insect netting 51 is connected to the corresponding window profiles 16, 17 along the roof opening that form the first framework. The insect netting 51 comprises a front panel 53 having multiple front pleats or front bellow sections 54 below the front profile 33, and two side panels 55 having multiple side pleats or side bellow sections 56. The front bellow sections 54 merge at their ends into the side bellow sections 56 below the side profiles 34. The bellow sections 53, 54 are stacked straight above each other when the ventilation window 30 is in the closed position.
As shown in figures 2A, 2B and 3, the netting system 50 comprises a guiding provision 70 for the insect netting 51. As best shown in figure 3, the guiding system 70 comprises a bow assembly 71 that is made of a metal rod, bar, profile, wire or tube, having in this example a thickness of about 5 millimeter, that is bend in the shown configuration. The guiding provision 70 comprises a mounting piece 72 that is in this example made of metal and that is mounted to the front profile 33 of the framework 32. The bow assembly 71 is at its top side hingeably connected with the mounting piece 72.
The bow assembly 71 comprises an elongate guide bow 77 that is convex towards the front panel 53. The guide bow 77 has a curvature with a practical constant radius around the hinge axis A of the ventilation window 30. The guide bow 77 extends at equal distances to the front bellow sections 56. The guide bow 77 continues at its top side into a not shown hinge rod that extends perpendicular to the guide bow 77 and that extends loosely through an aperture 73 in the mounting piece 72. At the opposite side this hinae rod .nues into an upper connecting section 80. The guide continues at its bottom side via a sharper V connecting sections 79, 80 are at their meeting ends rigidly attached to each other, in this example by means of a metal clamp 81 that is closed against the overlapping ends. The joint connecting sections 79, 80 together form a stiffening or reinforcement in the form of a counter bow that is concave towards the front bellow sections 54, having a curvature with about the same radius as the guide bow 77. The joint connecting sections 79, 80 provide rigidity to the guide bow 77. The entire bow assembly 71 is a form tab] e assembly or unity.
The guiding system 70 comprises a guide piece 75 that is in this example made of metal and that is mounted to the window profile 17. The guide piece 75 has an aperture 76 through which the guide bow 77 loosely extends to slide there through in direction D. The guiding provision 70 comprises multiple brackets 82 that are attached to the front bellow sections 54. The brackets 82 have an openingthrough which the guide bow 77 slidably extends. In this example a bracket 82 is attached to each front bellow section 54, but it is also possible to distribute less the brackets 82 over the bellow sections 54, for example by alternating.
The guide bow 77 supports the front bellow sections 54 in their sideward direction in any open position of the ventilation window 30. Thereby it is prevented that the unfolded front bellow sections 54 bulge out from, or collapse back into the ventilation passage when they are exposed to strong wind for example. The guide bow 77 guides the front bellow sections 54 when the ventilation window is closed in direction A, wherein the guide bow 77 slides through the aperture 76 after the subsequent front bellow sections 54 have landed Onto the horizontal window profile 17. In practice, the distance of the aperture 73 of guide piece 7 5 with respect to the hinge axis A might slightly deviate, in particular be slightly shorter than the distance of the aperture 76 of the mounting piece 72 with respect to the hinge axis A. This small deviation urges the bow assembly 71 to tilt or swing in direction E towards the hinge axis A when the ventilation window 30 is closed. In this manner it is prevented that the bow assembly 71 downwardly hits other components of the greenhouse 1 that are carried by the roof construction 10, such as horizontally extending screens.
In this example the guiding provision 70 is applied to the front bellow sections 54. The guiding provision 70 can on the same way be applied to the side bellow sections 56, wherein the mounting piece 72 and the guide piece 75 are mounted to the side profiles 34 and the corresponding slanting window profiles 16, and the brackets 82 are attached to the side bellow sections 56,
It is to be understood that the above description is included to illustrate the operation of the preferred embodiments and is not meant to limit the scope of the invention. From the above discussion, many variations will be apparent to one skilled in the art that would yet be encompassed by the spirit and scope of the present invention .
