Abstract

The cooker has a flexible reflective cover (10) for receiving sun rays and allowing heat to be concentrated on a definite point of the cooker, where the cover is maintained on movable branches (4) which are designed to deploy and fold the cover. The cover is maintained on the branches by an autoantigen ribbon (11). A hexagonal plate (3) with twelve sides is prolonged at edges of the cooker by the branches which are connected together by an articulation (5).

Description

1 Description1 Description

La présente invention concerne un dispositif qui .sert à cuire des denrées alimentaires, consistant en un système pliant permettant la concentration de la chaleur par le soleil. Les cuiseurs solaires du type parabole disponibles sur le marché pouvant atteindre une température de plus 200 C sont encombrants et quand ils ne sont pas en service, il n'y a pas la possibilité de les ranger dans un espace réduit. Le dispositif selon l'invention permet de remédier à cet inconvénient.  The present invention relates to a device for cooking food, consisting of a folding system for the concentration of heat by the sun. The parabolic solar cookers available on the market that can reach a temperature of over 200 C are bulky and when they are not in use, there is no possibility to store them in a small space. The device according to the invention overcomes this disadvantage.

Le cuiseur solaire pliant selon des modes particuliers de réalisation : Le cuiseur solaire se présente déplié (1) ou plié (2). Selon une première io caractéristique il est composé d'une plaque hexagonale (3) à 12 côtés prolongée à chaque arête par une branche (4) reliée par une articulation (5). Au centre de la pièce hexagonale (3) il est positionné un mât (6) fixe. Un tube cylindrique (7) coulisse autour du mât (6) et entraîne une deuxième pièce hexagonale (8), percée au centre, qui permet, par l'intermédiaire des baleines (9) et des articulations (12), 15 d'actionner manuellement le dispositif pour le déployer et d'obtenir un angle à 180 entre les branches (4) et la pièce hexagonale (3) ou pour replier l'ensemble du mécanisme, et obtenir un angle de 90 entre les branches (4) et la pièce hexagonale (3).  The solar cooker folding according to particular embodiments: The solar cooker is unfolded (1) or folded (2). According to a first characteristic it is composed of a hexagonal plate (3) with 12 sides extended at each edge by a branch (4) connected by a hinge (5). In the center of the hexagonal piece (3) is positioned a mast (6) fixed. A cylindrical tube (7) slides around the mast (6) and drives a second hexagonal piece (8), pierced in the center, which allows, via the whales (9) and the joints (12), to actuate manually the device to deploy it and to obtain a 180 angle between the branches (4) and the hexagonal part (3) or to fold the whole mechanism, and to obtain an angle of 90 between the branches (4) and the hexagonal piece (3).

20 L'ensemble des branches déployées (4) constitue l'espace qui correspond à la surface prévue pour réceptionner les rayons du soleil. Une bande de ruban auto agrippant (11) est collée sur chaque branche (4) afin de positionner une couverture réfléchissante (10). La couverture réfléchissante (10) est découpée de façon à s'adapter à la forme définie par les branches (4). 12 bandes de ruban auto agrippant 25 (11) sont également collées sur la couverture réfléchissante (10) afin de permettre l'accrochage sur les 12 branches (4). Une matière miroitée est collée sur la partir (3). Les branches (4) sont cintrées à 165 pour former une surface qui permet de réceptionner les rayons du soleil et concentrer la chaleur sur un point défini. 30 Une pièce (13) de forme triangulaire est fixée au bas du mât (6). Sur chaque côté de cette pièce il est fixé trois supports (14) articulés avec un système de blocage en position fixe. Les supports (14) constituent le support de la parabole. Les articulations (15) permettent le pliage des supports (14). Un des trois supports (14) 35 est prévu pour obtenir un écartement plus ou moins large par rapport aux deux autres supports (14), ceci, afin d'obtenir l'inclinaison de la parabole.  The set of deployed branches (4) constitutes the space which corresponds to the area intended to receive the sun's rays. A strip of self-gripping tape (11) is glued to each leg (4) to position a reflective cover (10). The reflective cover (10) is cut to fit the shape defined by the branches (4). 12 strips of self-gripping tape 25 (11) are also glued on the reflective cover (10) to allow attachment to the 12 branches (4). A shimmering material is stuck on the part (3). The branches (4) are bent at 165 to form a surface that can receive the sun's rays and concentrate the heat on a defined point. A triangular shaped piece (13) is attached to the bottom of the mast (6). On each side of this part is fixed three supports (14) articulated with a locking system in a fixed position. The supports (14) constitute the support of the parabola. The joints (15) allow the folding of the supports (14). One of the three supports (14) 35 is provided to obtain a more or less wide spacing relative to the other two supports (14), this, in order to obtain the inclination of the parabola.

Une tige filetée (16) est vissée de part en part sur les pièces hexagonales (3) et (8), et définit en même temps l'angle d'ouverture de la parabole. Sur l'autre 40 extrémité de la tige filetée (16) il est articulé une grille (17), cette grille (17) est maintenue sur son côté parallèle par une béquille (18). Un jeu d'écrous (19) est vissé sur la tige filetée (16) et sert de butoir pour positionner la grille (17) en position horizontale. La tige filetée (16) est décentrée par rapport au centre, afin de positionner la grille au centre de la parabole.  A threaded rod (16) is screwed right through to the hexagonal pieces (3) and (8), and at the same time defines the angle of opening of the dish. On the other 40 end of the threaded rod (16) is articulated a grid (17), the grid (17) is maintained on its parallel side by a stand (18). A set of nuts (19) is screwed onto the threaded rod (16) and serves as a stopper for positioning the grid (17) in a horizontal position. The threaded rod (16) is off center relative to the center, to position the grid in the center of the dish.
