Description

INSULATING CLOSURE SYSTEM

OF A BUILDING BAY

  The subject of the invention is a system for insulating closure.

of a building bay.

  Whatever their type, the buildings have openings which are closed by means of doors, French windows, or windows. In the last two cases, glazing is carried by a frame which is mounted mobile in a sleeping frame. placed in the bay These glazings constitute a means of shutter, while allowing the passage of sunlight; but whether they are single, double or even triple, they simultaneously allow the passage of heat rays, because they constitute neither a barrier opposing during the hot season the passage of solar rays in the room, nor a barrier opposing during the cold season when calories go by

  from the inside to the outside of this room While, for the sake of economy

  energy efficient, effective means of insulation are commonly used in buildings, patio doors and windows thus always constitute areas of heat loss during the cold season and areas of unnecessary and harmful intake of calories during the hot season Habits, lifestyle and aesthetics lead, on the contrary, to increase the surface area of the bays of a building compared

to that of its walls.

  Whether windows or patio doors, the closing element of a bay is also often associated with a more or less opaque shutter which is placed outside relative to this element and which, by closing, effectively obscures the glazing and thus prevent either the penetration of sunlight into the room, or the loss of calories by passing outside The operation of a

  exterior shutter requires, however, for its opening and for its closing

  ture, the opening of the French window or window, which inevitably leads to a communication of the room with the outside, and therefore to a loss of calories during the cold season and to an entrance

  heat during the hot season.

  It is certainly also known to use either external blinds whose operation does not require the opening of a window, or internal shutters which can be folded against the internal face of a French window or window; but neither these blinds nor these interior shutters can be considered as closing accessories providing good insulation. Patio doors and windows are therefore in all cases significant sources of heat loss during the cold season and heat increase during the hot season, due to the disadvantage of permeability of glazing vis-à-vis solar rays

  and calories inside the room.

  The invention takes advantage of this drawback to produce a veritable

  ble air conditioning of premises It has for this purpose a closing system in which the French window or window and its glazing are associated with a folding shutter which, made of an insulating material, is located inside with respect to the glass closing element and

  delimits, with it, a free space giving rise to the formation of a cous-

  sin of air having at least ten centimeters in thickness and constituting, over the entire surface of the opening, a barrier between the glazed closing element and the insulating flap, the glazing of the closing element combined with the insulating flap leading during the day to a greenhouse effect which increases the temperature of the air mattress retained by this dam, and the shutter associated with this air mattress constituting during the night an insulating barrier

  against heat loss to the outside.

  This barrier considerably reduces the passage, from inside to outside and vice versa, of the rays carrying calories or frigories It therefore constitutes an effective means of isolating the room when the shutter is put in the position of use; but it also constitutes, and this is another characteristic of the invention, a means allowing

  real air conditioning in this room.

  This goal is achieved by associating the shutter with an arrangement that allows it to

  either to reflect the sun rays carrying calories, so

  avoid the formation of a warm air mattress between the closing element

  ture and the shutter, or on the contrary to absorb these solar rays so that either

operated this hot air mattress.

  Depending on the orientation of the wall comprising the opening to which this closure system is adapted, the shutter may include either one or the other of the two above-mentioned arrangements; but it can also be equipped with a transformable or adaptable system allowing both

modes of use.

  The invention will also be well understood and its advantages thus

  that other characteristics will emerge from the description which follows,

  with reference to the appended schematic drawing representing, by way of example

  ple nonlimiting, an embodiment of this system for the insulating closure of a building bay, in the case of a French window:

  Figures 1, 2 and 3 are perspective views showing respective

  in the open, closed and half-open position, the flap which constitutes the essential element of this system; Figures 4, 5 and 6 are views in horizontal section of this flap respectively in the closed position, in the open position and in the open position;

  Figures 7 and 8 are vertical section views of one of the pan-

  shutters in the case of two embodiments of the arrangement associated with its inner face;

  Figure 9 is a view in longitudinal vertical section of the tra-

  pours from the sleeping frame in which the flap is mounted.

  In this drawing, (1) designates the wall of any building in which is fitted a bay (2) closed by a French window (3). On the inside face of the wall (2), a sleeping frame (4) is fixed to the periphery of the opening (2) This frame consists of two uprights (5) and an upper crosspiece (6) By its uprights ( 5), this frame (4) is used for fixing, by means of hinges (7) of a flap designated so

general by (8).

  This flap (8) is constituted by two leaves each formed by two panels respectively (9) and (10) The panel (9) is hingedly attached to the frame (4) by means of the hinges (7); and the panel (10) is articulated to the panel (9) by spring hinges

  (12); the leaf is also connected - in an articulated manner to the upper cross member -

  frame (6) of the frame (4) by means of a compass (13).

  Thanks to this arrangement, the two panels (9, 10) of each leaf of the shutter (8) can be brought back either to the fully open position (FIGS. 1 and 5), or to the completely closed position (FIGS. 2 and 3). , or still in any open position such

  than that shown in Figures 3 and 6.

  When the flap (8) is open, it internally releases the entire opening (2), and the two panels (9, 10) of each leaf are folded over one another and on the inside of the wall ( 1). When on the other hand the shutter (8) is closed, the two panels (9, 10) of each leaf are unfolded in the extension of one another and are located at a relatively great distance from the French window (3) This distance is a function of the depth of the frame (4),

  the thickness of the wall (1) and the position of the French window (3) inside

  bay (2) The distance between the shutter (8) in the closed position

  ture and the French window (3) is in any case greater than ten centimeters.

  This distance thus makes it possible to reserve a thick air mattress inside

  Laughing bay (2) between the French window (3) and the shutter (8) During the cold season, this air mattress is an excellent means of insulation between the outside atmosphere and the interior of the room; and in sunny weather, it is possible to increase the temperature of this air mattress if means have been provided so that the sun's rays coming to strike the shutter after passing through the glazing of the French window (3) are, not reflected outside, but on the contrary absorbed in space

  delimited by the French window (3) and by the shutter (8).

  This goal can be achieved by having an absorbent coating on the inside of the panels constituting the two leaves of the shutter. It thus becomes possible to obtain, thanks to the sun's rays, a mattress of hot air in the space delimited by the door. window (3) and through the shutter (8) Means can then be provided to allow the hot air thus accumulated in this space to circulate and to go towards the room. For this, orifices (14) are drilled in the upper crossmember (6) of the frame (4); and above this cross

  (6) is slidably mounted a longitudinal and horizontal flap (15) comprising

  as many orifices (16) whose number, dimensions and arrangement correspond to those of the orifices (14) of the crosspiece (6) This flap (15) can occupy two positions: one in which the orifices (14, 16 ) are aligned, and the other in which they are misaligned The first position allows air circulation between the room and the space delimited by the French window (3) and the shutter (8); the other position isolates on the contrary

2 541719

  the room and this space Means are provided to allow the shutter

  (15) to pass from one of these two positions to the other. These means can

  wind consist of an elastic system (17) and a draw cord (18)

provided with attachment means.

  As indicated above, the inner face of the two panels (9, 10) of the leaves of the shutter (8) is advantageously provided with an absorbent coating to avoid the reflection of solar rays outside. In certain cases and during in the hot season, it may however be advantageous to return the sun's rays to the outside to avoid an accumulation of heat between the French window

  (3) and the shutter (8) It is then preferable to arrange in a reflective-

  the inner face of the panels (9, 10) of the leaves of the shutter (8)

  and to provide this inner face with a removable curtain.

  In the case of the embodiment represented in FIG. 7, each panel (9, 10) of the leaves of the shutter comprises, in the upper part of its inner face, a roller system (19) intended for a curtain (20) the free end of which comprises means making it possible to fix it to a fastening system (21) provided in the lower zone of the flap (8) The external face of this curtain (20) is dark in color in order to be absorbent for solar rays Under these conditions, when the curtain is unrolled, the solar rays are absorbed in the space delimited by the French window (3) and by the shutter (8) On the other hand, when the curtain (20) is rolled up the winding system (19), the front

  reflective interior of the shutter returns the sun's rays to the outside.

  In the case of the alternative embodiment shown in FIG. 8, each panel of the flap (8) comprises an interior curtain (22), the two faces of which are one reflecting and the other absorbing; and the curtain is fixed on the shutter panel (8) so that at will

  on the outside, it has its reflecting or absorbing face.

  Depending on the season: hot or cold, the curtain (22) is therefore used in

one position or the other.

  It is important to note that the flap (8) can also be used, not only in the fully open position or in the fully closed position, but also in one or other of a plurality of positions. entr'ouverture Figures 3 and 6 show such a position which has the effect of allowing, benefiting from the greenhouse effect due to the combined presence of the glazing and the insulating flap, to obtain air circulation by means of the presence of interstices and openings (23) which are reserved at the top and bottom of the flap (8), when

  is not fully closed As a result, the sun's rays pass through

  the glazing, but stopped by the shutter, cause an increase in the temperature of the air mattress located between the glazing and the shutter, and thus this hot air animated by a natural upward movement

circulates towards the room.

  As is obvious and as appears from what has been indicated above, the invention is not limited to the sole embodiments of this system for closing a building bay which have been above shown as examples; on the contrary, it embraces all the variant embodiments thereof and it of course extends its field of application to the closing of all kinds of windows, that is to say both windows and French windows, the shutter and its frame which may be an integral part of a set comprising the French window or

  the window, as well as possibly a shutter or other means of blocking out

  external tion Finally, it is possible to associate with the shutter means allowing its automatic operation as a function of the temperature differences which may exist between the exterior, the interior and the mattress

  intermediate and depending on sunshine and time.
