  • the inner frame 20 is constructed by assembling or welding four rectangular bars together.
  • the hollow portion in the inner frame 20 is divided into inner and outer hollow portions 22 and 23 by a baffle 24.
  • a plurality of engaging slits 26 are formed on the inner surface of the inner frame 20 at regular intervals to be engaged with the cross-shaped bars 30.
  • a fixing slit 27 is longitudinally formed on the outer surface ofthe inner frame 20 to lock the cover 40.
  • the engaging slit 26 comprises a first slit 26a longitudinally formed on the inner surface of the inner frame 20 and second slits 26b regularly arranged to be perpendicular to the first slit 26a. This is because the cross-shaped bar 30 has a cross shape. Accordingly, the shape of the engaging slit 26 may be varied according to the shape ofthe bar 30.
  • the fixing slit 27 is employed to fix the outer edge ofthe vinyl sheet 41 while the vinyl sheet 41 is supported by a wedge bar 43.

  • the rib 32 to be inserted into the engaging slit 26 ofthe inner frame 20 is formed to be relatively long together with the rib 31.
  • the cover 40 can be made of a variety of materials. Since a greenhouse 41 requires appropriate lighting, the cover 40 is made of a soft transparent sheet or transparent body such as a glass plate 42. For example, when the cover 40 is made of a vinyl sheet 41, the peripheral portion of the vinyl sheet 41 is inserted into and fixed in the fixing slit 27 ofthe inner frame 20 by the wedge bar 43, so an air layer is formed in the opening 25 of the inner frame 20. For ease of fabrication, the vinyl sheet 41 is formed in the form of a connected two-fold sheet to allow the inner frame 20 to be inserted into the vinyl sheet 41.
  • An outer frame 50 is constructed by assembling front, rear, right and left bars together in the form of a rectangular frame.

  • the inner and outer frames 20 and 50 and the cross-shaped bars 30 are preferably made of light metal or synthetic resin of high strength.
  • a plurality of cross-shaped bars 30 are assembled in the form of a lattice by engaging the cross-shaped bars 30 with one another using the slits 35, 36 and 37, the front, rear, left and right bars are connected to each other to allow the neighboring ends of each cross-shaped bar 30 to be inserted into corresponding engaging slits 26, and, thereafter, the neighboring ends of the bars are connected to each other.
  • the inner frame 20, into which the cross-shaped bars 30 are fitted is surrounded by the barrel-shaped vinyl sheet 41, and two wedge bars 43 are inserted into the fixing slit 27 from the sides of the vinyl sheet 41.
  • the vinyl sheet 41 is held by the inner frame 20 while being tightly pulled by the wedge bars 43.
  • the elastic plates 28 of the inner frame 20 are elastically deformed by the wedge bars 43, so the vinyl sheet 41 is securely held by the elastic plates 28.
  • a glass plate 42 instead of a vinyl sheet 41 is employed as the cover 40.
  • two glass plates 42 are disposed on the side surfaces ofthe inner frame 20, the front, rear, right and left bars of the outer frame 50 are fixedly attached to each other to cover the peripheral edges of the two glass plates 42, and the inner ends of the outer frame 50 and the two glass plates 42 are fixedly attached to each other by a bonding agent, thereby forming a panel.
  • the need for the wedge bar 43 is obviated.
  • Figs. 6 to 8 there is illustrated the foldable panel 60 for a greenhouse.

  • the same reference numerals are assigned to the same or similar components, and the detailed description ofthe components are omitted.
  • the foldable panel 60 is comprised of two body halves 61 and 62 that are separated from each other.
  • the foldable panel 60 is constructed by foldably attaching the body halves 61 and 62 to each other by a hinge 63.
  • Two pairs of cover flanges 65 and 66 are provided on the side ends of the body halves 61 and 62, that is, both sides ofthe body halves 61 and 62 arranged to construct a greenhouse, to cover the peripheral edges ofthe fixed panels 10.
  • the cover flanges 64 serve to prevent rainwater from infiltrating the interior of a greenhouse through the gap between each ofthe fixed panels 10 and each of the foldable panels 60.
  • Each of the cover flanges 64 is formed to cover at least each of the rainwater intercepting barriers 53.
  • packings 67 can be provided on the lower surfaces of the outer portions ofthe cover flanges 65 and 66 together with the cover flanges 65 and 66 to come into contact with the upper surfaces of the fixed panels 10 and, thereby, keep airtightness between each ofthe cover flanges 65 and 66 and each ofthe fixed panels 10.

  • FIGs. 9 to 11 illustrate a ventilation system for a greenhouse that is constructed using the panels ofthe present invention.
  • the ventilation system for a greenhouse according to the present invention is constructed by alternately arranging one or more foldable panels 60. This structure may be applied to only the ceiling of a greenhouse, or the ceiling and sidewalls of a greenhouse if necessary.
  • the fixed panels 10 are fixedly and regularly attached to the framework of a greenhouse, for example, via C-shaped steel, while the foldable panels 60 are foldably attached to the framework by movable support means.

  • the one-dot chain lines of the drawing indicate the state in which the foldable panel 60 is opened.
  • the greenhouse 100 according to the present invention has an opening ratio of about 50%.
  • the opening ratio of the greenhouse 100 can be increased to 85% at a maximum by controlling the widths of the fixed and foldable panels 10 and 60 within the given entire size of the greenhouse. That is, since the ventilation system for a greenhouse of the present invention is constructed by alternately arranging the fixed panels 10 and the foldable panels 60, the greenhouse 100 has an opening ratio of about 50% when the width LI of the foldable panel and the width L of each fixed panel 10 are equal as shown in Fig. 12a, and has an increased opening ratio when the width LI' of the foldable panel 60 is two times as large as the width L' ofthe fixed panel 10 as shown in Fig. 12b or the width LI" ofthe foldable panel 60 is four times as large as the width L" ofthe fixed panel 10 as shown in Fig. 12c.
  • an increase in the width of the foldable panel 60 corresponds to the width of the fixed panel 10.
  • the width LI, LI' or L' of the foldable penal 60 is set within about 2m. The reason for this is that if not, strength against a strong wind is considerably reduced when the foldable panel 60 is opened, that is, that the structural stability ofthe greenhouse is achieved.
  • the opening of a pane ofthe greenhouse is divided into two portions. That is, the upper portion of the opening is fully opened, while the lower portion of the opening is laterally opened, thereby increasing the opening ratio ofthe greenhouse 100 and allowing the inflow and outflow of indoor and outdoor air to be smooth and rapidly performed. That is, as shown in Fig. 9, indoor air of high temperature rapidly flows out ofthe greenhouse 100 through the upper fully opened portion ofthe opening and outdoor air of low temperature flows into the greenhouse 100 through the lower laterally opened portion of the opening. Accordingly, during hot seasons, the indoor temperature of the greenhouse 100 can be kept appropriate to the growth of agricultural products and the appropriate lighting can be maintained by natural ventilation without cooling means.

Meanwhile, the operation of the foldable panel 60 can be performed individually by an exclusive motor 88 assigned to the foldable panel 60. As shown in Fig.
  • a single rotating shaft 81' is formed to be long so as to take charge of a plurality of foldable panels 60, supported by a plurality of bearing blocks 83 and provided at regular intervals with a plurality of pinions 82, thereby allowing a single motor 88 to selectively open or close a plurality of panes by folding the foldable panels 60 at the same time.
  • all the foldable panels 60 situated on the same plane can be operated by a single motor 88; while when the greenhouse 100 is large-sized, it is preferable to divide the foldable panels 60 into groups and separately operate the groups.
  • the present invention is described with regard to the greenhouse for an illustrative purpose, the present invention is not limited to the greenhouse.
  • the present invention can be applied to structures including a cattle shed, such as a cow, domestic fowl or pig shed, and a commodity storage house that need ventilation.
  • the greenhouse can withstand a heavy wind when the panes ofthe greenhouse are opened, the opening ratio ofthe greenhouse is increased, and the inflow and outflow of indoor and outdoor air can be smoothly and rapidly performed via the panes, thereby being capable of keeping the indoor temperature of the greenhouse appropriate to the growth requirements of agricultural products by natural ventilation without cooling means.
  • each of the panels constituting the greenhouse is provided with an air layer between its upper and lower covers, so the greenhouse has superior insulation performance, thereby being advantageous to the maintenance of the appropriate indoor temperature ofthe greenhouse.
  • the ventilation, insulation and strength of the greenhouse are considerably improved and an decrease in cultivation costs is achieved. Additionally, when a structure, such as a cattle shed or factory, etc. is constructed of panels, superior ventilation can be achieved.

Abstract

La présente invention concerne un système de ventilation destiné à une serre. Ce système de ventilation comprend des panneaux fixes et pliables composés chacun de cadres, de barres cruciformes et de structures doubles afin d"augmenter les performances d"isolation de la serre et de faciliter la construction et l"entretien de la serre en raison de sa structure simple. Ce système comprend également des panneaux composés chacun de panneaux pliables comprenant des moitiés divisée pliables autour d"une charnière, situés dans le toit et les parois latérales de la serre, ainsi qu"un dispositif d"entraînement destiné à ouvrir et à fermer sélectivement ces panneaux. Par conséquent, lorsque les panneaux sont ouverts, l"air à température élevée s"échappe de la serre par les parties ouvertes et l"air extérieur à faible température entre dans la serre par les parties ouvertes latéralement.
