Abstract

Device for permanently reflecting the sun towards dark parts of a building. The invention relates to an autonomous device allowing the sun to be reflected in a perfect and continuous manner, for a maximum of time, towards the shadowy areas of a building , to brighten up dark rooms.It consists of a certain convex spherical part, smooth and reflective (2) which according to its characteristics will not limit the radiation. This part (2) rests on a support (4) allowing it to be positioned at a precise location, to ensure its function. A system is provided to neutralize the device, either by camouflage, or by displacement (5) to (II), in the event of high temperatures. The device according to the invention is particularly intended to provide mainly sunlight to the rooms to the north of a house. .

Description

The present invention relates to a device for reflecting the sun

  all day long, with continuous and self-orientating radiation, towards the shaded rooms of a building (villas, offices, hospitals, etc.), mainly in the North, but also in the East and West from that the sun has turned: It will then require a device by orientation, one in the North, one in the East and one in the West, to see per example,

  a completely sunny house.

  Io The current technique makes it possible to reflect the sun towards gray areas, but remains incomplete. There are indeed: - the flat mirrorNeed to reorient several times

  the mirror as a function of the position of the sun I5 - the convex mirror: Partial radiation.

  - the spherical mirror with convex bands: Radiation ceased

  by the joints, radiation in bands.

  - the spherical faceted mirror: Discontinuous radiation.

  - the revolving house: Choice of the sunny room, the

  other rooms remaining in the shade.

  On the other hand, all these mirrors with limited reflection are not used to brighten the areas

shade of a house.

  The device according to the invention overcomes the drawbacks. According to a first characteristic, it comprises a smooth convex, total or

  part. The diameter is proportional to the volume to be lit.

  The mirror is placed on a support or any other fixing element, just above the height of the house, to avoid glare, at the center of the wall and at a distance corresponding to the half-height of the house. In this way, the sun is captured all day. It is however possible to neutralize the device, in case of high heat, either by veiling the mirror (protective cover, screen, etc.), or by adapting a pivoting system, etc. * .. -2 According to particular modes of realization: -The reflecting surface can be limited simply to the part necessary for the desired goal: Half-sphere for the North, quarter-sphere for the East and the West. The remaining neutral part can have any shape or be nonexistent. -The diameter of the spherical surface may have a

  standard size corresponding to an average house.

  -The device can have any support, étuI0 dié nevertheless depending on the resistance of the wind.

  -The support or pillar can be adjustable depending on the height of the house. Its height can be standard corresponding to an average house. For larger dimensions.,

  the realization will be made to order.

  I5 -To neutralize the device, the sphere can be pivoted, the neutral part being placed opposite its

  initial position. A swivel system is then necessary.

  -The reflective part can be fitted with a shell

which folds down.

  -The sphere can be sliding along the pillar or adjustable if the pillar is adjustable. These characteristics are used to put a protective cover during hot weather and to clean the mirror when the radiation is altered. -The pillar may have an aspect of scale, allowing access to- the sphere, to cover it with protection and

possibly clean it.

  - Cleaning can be carried out by professionals. If: the radiation is slightly altered, a strong flow of water may suffice. The accompanying drawings illustrate the invention: FIG. I represents an overall view of the device for

  the invention, placed to the north of a house.

  FIG. 2 represents the device of the invention according to

  a particular embodiment.

  With reference to these drawings, the device comprises a sphere (I) with two shells, assembled perpendicularly, one is a smooth mirror (2), the other is neutral (3), -3 the whole resting on a pillar (4). This device is placed to the North of the house, mirror shell (2) to the South. This is made of glass. The surface is then metallized inside. The neutral shell (3) can be made with a different, painted material. At the top of the pillar is an axis (5) .fixed in the center On this axis (5) rests a ball (6) and a movable disc (7)

  whose diameter exceeds that of the pillar (4).

  The disc (7) has two opposite orifices (8) from which I0 leave two bolted rods (9), of harsh steel, descend along the pillar (4) up to the height of a man. They are connected at their ends by a metal circle (I0) which surrounds the pillar (4), without touching it. Two diametrically opposed screws (II) start from the circle (I0) to tighten the

  I5 pillar (4) so that the assembly remains well fixed.

  In the last step, the sphere (I) is fixed on the

mobile disc (7).

  To neutralize the device, simply unscrew the two screws (II) and orient the two rods (9) by half a turn and tighten again; the neutral shell (3) being placed at the

South and the mirror shell (2) to the North.

  Finally, the thickness of the pillar (4) is equivalent to the size of electrical poles or large city lights, hence resistance depending on the force of the wind

maximum in the region.

  According to a variant not illustrated, the pillar may include an electromechanical system (or even more elaborate according to current technology), which will rotate the

half-turn sphere.

  By way of nonlimiting example, the pillar will have a

  height of 10 m visible and 3 m approximately in the ground.

  The sphere, a diameter of 60 to 70 cm. the stems, one length

8.50 m.

  The device according to the invention is particularly intended to have a completely sunny house all the time.

  day, heating savings and a therapeutic effect.
