Abstract

A terrace heating device includes a reflector (7) for reflecting rising heat from a heater (8) downward toward patrons on a terrace. An umbrella-like cover (10) is arranged on a support pole above the heater. The umbrella-like cover is articulable between an open position (FIG. 2b) and a closed position (FIG. 2a). The open position corresponds to a position of use in which the umbrella-like cover traps heat, holding the heat close to the patrons. In use, the umbrella-like cover is opened and the heater turned on to heat the space underneath the umbrella-like cover. The closed position corresponds to a storage position in which the umbrella-like cover folds about the support pole and a safety switch turns off the heater automatically. The umbrella-like cover is preferably defined by a detachable material for the cover which material is selected in accordance with the season, e.g., insulated for winter.

Description

DISPOSITIF DE CHAUFFAGE POUR TERRASSETERRACE HEATING DEVICE
La présente invention concerne un dispositif de chauffage pour terrasse destiné à être disposé sur des terrasses professionnelles de restaurants ou de bars ou sur des terrasses de type privé, de manière à permettre l'utilisation desdites terrasses quelle que soit la température extérieure comme, par exemple, en hiver.The present invention relates to a patio heating device intended to be placed on professional restaurant or bar terraces or on private type terraces, so as to allow the use of said terraces whatever the outside temperature such as, for example , in winter.
On connaît des dispositifs de chauffage possédant des éléments chauffants utilisant le gaz propane comme combustible, qui peuvent éventuellement équiper les terrasses en basses saisons. Les éléments chauffants sont généralement disposés en hauteur, de manière à rayonner vers le bas. De tels appareils présentent toutefois de nombreux inconvénients liés à leur utilisation et notamment celui de la déperdition de chaleur obligeant le restaurateur, le cafetier ou l'utilisateur à disposer un grand nombre de ces appareils sur sa terrasse afin d'obtenir une température suffisante.Heating devices are known which have heating elements using propane gas as fuel, which can optionally be fitted to terraces in low seasons. The heating elements are generally arranged in height, so as to radiate downwards. However, such devices have many drawbacks related to their use and in particular that of the heat loss forcing the restaurant owner, the cafeteria maker or the user to have a large number of these devices on his terrace in order to obtain a sufficient temperature.
De plus, ces appareils chauffent l'air par rayonnement et l'air chaud ayant tendance à monter, un tel système ne permet pas d'obtenir une température satisfaisante, notamment au niveau des membres inférieurs (pieds, jambes), qui, disposés sous une table, ne profitent aucunement du rayonnement. La déperdition de chaleur occasionnée lors de l'utilisation de ces différents appareils chauffants présents sur le marché provoque une consommation élevée du combustible qui les alimente comme, par exemple, le propane, dès que l'on désire maintenir une température élevée.In addition, these devices heat the air by radiation and the hot air tends to rise, such a system does not make it possible to obtain a satisfactory temperature, in particular at the level of the lower limbs (feet, legs), which, arranged under a table, do not benefit from radiation at all. The heat loss caused during the use of these various heating devices present on the market causes a high consumption of the fuel which supplies them such as, for example, propane, as soon as one wishes to maintain a high temperature.
Ainsi, la présente invention se propose de résoudre les divers inconvénients précités grâce à des moyens simples, sûrs et efficaces. Selon l'invention, le dispositif de chauffage destiné à chauffer un espace tel qu'une terrasse par exemple est du type comportant des moyens de chauffage comprenant au moins un élément de chauffage disposé sur ou porté par un mât porteur, caractérisé en ce qu'il comporte des moyens d'isolation destinés à éviter la déperdition de la chaleur, lesdits moyens d'isolation étant mobiles entre deux positions, une position ouverte déployée correspondant à la position d'utilisation, et une position fermée en position de rangement.Thus, the present invention proposes to solve the various aforementioned drawbacks by simple, safe and effective means. According to the invention, the heating device intended for heating a space such as a terrace for example is of the type comprising heating means comprising at least one heating element disposed on or carried by a carrying mast, characterized in that it comprises insulation means intended to avoid the loss of heat, said insulation means being movable between two positions, an open deployed position corresponding to the position of use, and a closed position in the storage position.
Selon une caractéristique complémentaire, les moyens d'isolation sont constitués par une coupole de grande dimension disposée en position ouverte dans un plan sensiblement horizontal situé au-dessus de l'élément de chauffage.According to an additional characteristic, the insulation means consist of a large dome arranged in the open position in a substantially horizontal plane located above the heating element.
Selon une autre caractéristique complémentaire, la coupole constituant les moyens d'isolation est constituée soit par une toile, soit par un ensemble d'éléments rigides ou semi-rigides, ceux-ci étant articulés sur le mât porteur ou sur une pièce complémentaire solidaire du mât.According to another additional characteristic, the dome constituting the insulation means is constituted either by a fabric, or by a set of rigid or semi-rigid elements, these being articulated on the carrying mast or on a complementary piece integral with the mast.
Ajoutons que la coupole est déployée dans une position ouverte, ou repliée dans une position fermée grâce à des moyens d'actionnement et de positionnement, tandis que des moyens de réflexion des radiations ou du rayonnement de l'élément chauffage sont avantageusement prévus, ces moyens étant constitués par au moins une coupole réfléchissante.Let us add that the dome is deployed in an open position, or folded back in a closed position by means of actuation and positioning, while means for reflecting radiation or radiation from the heating element are advantageously provided, these means being constituted by at least one reflecting dome.
Selon une autre caractéristique du dispositif de chauffage pour terrasse, les moyens de réflexion sont constitués par les moyens d'isolation comme par exemple par la toile.According to another characteristic of the patio heater, the reflection means are constituted by the insulation means such as for example by the canvas.
Selon une variante d'exécution, le mât porteur est déporté de manière à se trouver à l'extérieur de l'espace situé à l'applomb des moyens de chauffage et des moyens d'isolation. On comprendra que les moyens d'isolation permettent d'arrêter la dispersion des radiations et/ou de la chaleur qui pourraient partir dans l'atmosphère, tandis que grâce à la possibilité de mettre en position fermée le dispositif, ce dernier est facilement déplaçable pour être déplacé ou stocké. Grâce à la grande dimension de la coupole il y aura une bonne conservation du volume d'air chauffé assurant un parfait confort des utilisateurs avec un minimum d'énergie consommée.According to an alternative embodiment, the support mast is offset so as to be outside the space located at the height of the heating means and insulation means. It will be understood that the isolation means make it possible to stop the dispersion of radiation and / or heat which could go into the atmosphere, while thanks to the possibility of placing the device in the closed position, the latter is easily movable for be moved or stored. Thanks to the large size of the dome there will be a good conservation of the volume of heated air ensuring perfect comfort for users with a minimum of energy consumed.

Selon l'invention, le dispositif de chauffage pour terrasse portant la référence générale (1) comporte des moyens de chauffage qui sont constitués par au moins un élément de chauffage (8). Ledit élément de chauffage peut être de type chauffage radiant alimenté par exemple au gaz par des moyens d'alimentation (MA), ledit gaz pouvant être par exemple, le propane ou le butane. L'élément de chauffage (8) peut également être de tout type comme par exemple électrique ou fonctionnant au gasoil, les moyens d'alimentation (MA) correspondant avantageusement au type d'élément de chauffage utilisé. Ledit élément de chauffage (8) est porté par des moyens de maintien, tels qu'un mât porteur (3), de manière à permettre avantageusement audit élément de chauffage d'être situé à une hauteur (L) du sol pouvant être comprise entre 1 et 3 mètres. La radiation de l'élément et/ou la chaleur fournie par la combustion peut, de plus, être avantageusement orientée ou dirigée vers le bas de manière à chauffer directement l'espace (5) situé à l'aplomb dudit élément de chauffage (8). Notons que l'élément de chauffage (8) se trouve avantageusement au sommet du mât porteur (3).According to the invention, the patio heating device bearing the general reference (1) comprises heating means which consist of at least one heating element (8). Said heating element can be of the radiant heating type supplied for example with gas by supply means (MA), said gas being able to be, for example, propane or butane. The heating element (8) can also be of any type such as for example electric or operating with diesel, the supply means (MA) advantageously corresponding to the type of heating element used. Said heating element (8) is carried by holding means, such as a carrying mast (3), so as to advantageously allow said heating element to be situated at a height (L) from the ground which may be between 1 and 3 meters. The radiation of the element and / or the heat supplied by the combustion can, moreover, be advantageously oriented or directed downwards so as to directly heat the space (5) situated directly above said heating element (8). Note that the heating element (8) is advantageously located at the top of the supporting mast (3).
Selon l'invention, les moyens de chauffage comportent des moyens de réflexion (MR) des radiations ou du rayonnement produit par l'élément de chauffage (8). Selon plusieurs modes de réalisations décrits ci-après, les moyens de réflexion sont constitués par une coupole réfléchissante (7) en forme de calotte orientée vers le bas (BA) qui est disposée au-dessus de l'élément de chauffage (8) afin de réfléchir vers l'espace (5) les radiations de l'éléments. Par ailleurs, le dispositif de chauffage (1) selon l'invention comporte des moyens d'isolation (MI) destinés à éviter la déperdition de chaleur que l'on produit dans l'espace (5) situé entre le sol et l'élément de chauffage.According to the invention, the heating means comprise means for reflecting (MR) the radiation or the radiation produced by the heating element (8). According to several embodiments described below, the reflection means consist of a reflective dome (7) in the form of a downward-facing cap (BA) which is arranged above the heating element (8) so to reflect towards the space (5) the radiations of the elements. Furthermore, the heating device (1) according to the invention comprises insulation means (MI) intended to prevent the loss of heat which is produced in the space (5) located between the ground and the element. of heating.
Selon un premier mode de réalisation du dispositif de chauffageAccording to a first embodiment of the heating device
(1) pour terrasse illustré figures 1, 2a et 2b, les moyens d'isolation (MI) sont constitués par une toile (2), ladite toile pouvant être déployée dans une position dite position ouverte (A) où la toile (2) est disposée au- dessus de l'élément de chauffage (8) tel qu'illustré figures 1 et 2b ou être repliée dans une position dite position fermée ou position de rangement (B) comme le montre la figure 2a. Le déploiement et le rangement de la toile (2) s'effectuent grâce à des moyens d'actionnement et de positionnement (MAP) destinés à permettre, d'une part, le passage de la toile de sa position ouverte (A) à sa position fermée (B) et inversement, et d'autre part, à positionner, à tendre ou à mettre en forme la toile (2), notamment lorsqu'elle est déployée en position ouverte (A).(1) for the terrace illustrated in FIGS. 1, 2a and 2b, the insulation means (MI) consist of a fabric (2), said fabric being able to be deployed in a position called the open position (A) where the fabric (2) is arranged above the heating element (8) as illustrated in Figures 1 and 2b or be folded into a position called closed position or storage position (B) as shown in Figure 2a. The deployment and storage of the fabric (2) is effected by means of actuation and positioning (MAP) intended to allow, on the one hand, the passage of the fabric from its open position (A) to its closed position (B) and vice versa, and secondly, to position, stretch or shape the fabric (2), especially when it is deployed in the open position (A).
La toile (2) et les moyens d'actionnement et de positionnement (MAP) sont portés par les moyens de maintien qui comportent au moins un mât porteur (3) monté sur un socle (4), ledit socle étant destiné à être installé sur la terrasse. De ce fait, le dispositif de chauffage pour terrasse (1) est destiné à être installé de manière fixe pour définir entre le sol et les moyens d'isolation (MI), un espace chauffé (5) dont la surface de chauffe est comprise entre 10 m 2 et 30 m 2.The fabric (2) and the actuation and positioning means (MAP) are carried by the holding means which comprise at least one carrying mast (3) mounted on a base (4), said base being intended to be installed on the terrace. Therefore, the patio heater (1) is intended to be installed in a fixed manner to define between the floor and the insulation means (MI), a heated space (5) whose heating surface is between 10 m 2 and 30 m 2 .
Selon ce premier mode de réalisation, le mât porteur (3) constituant les moyens de maintien (MM) est disposé selon un axe vertical (XX1) à l'aplomb de la zone centrale (6) de la toile (2). Ledit mât porteur est destiné à porter, d'une part, l'élément de chauffage (8) et la coupole (7), et d'autre part, la toile (2) ainsi que les moyens d'actionnement et de positionnement (MAP) de ladite toile.According to this first embodiment, the carrying mast (3) constituting the holding means (MM) is arranged along a vertical axis (XX 1 ) perpendicular to the central area (6) of the fabric (2). Said supporting mast is intended to carry, on the one hand, the heating element (8) and the dome (7), and on the other hand, the fabric (2) as well as the actuation and positioning means ( MAP) of said canvas.
Selon ce premier mode de réalisation, la toile (2) est avantageusement de forme circulaire et comporte une zone centrale (6) fixe et immobile disposée sensiblement au sommet (3a) du mât porteur (3) sur un support rigide (40) porté par le mât et une portion de toile périphérique (10). Ladite zone centrale (6) également de forme circulaire dans ce mode de réalisation est disposée dans un plan horizontal et est de dimension supérieure aux dimensions de la coupole (7) qu'elle surplombe. La portion de toile périphérique (10) prolonge vers l'extérieur la zone centrale (6) de la toile, ladite portion pouvant être déployée ou repliée sous l'action des moyens d'actionnement et de positionnement (MAP). Le diamètre de la toile (2) est avantageusement compris entre 1,2 m et 5 m afin d'isoler en dessous un espace (5) de dimension suffisante pour permettre à plusieurs personnes de s'y installer.According to this first embodiment, the fabric (2) is advantageously circular in shape and comprises a central and stationary area (6) fixed and stationary disposed substantially at the top (3a) of the carrying mast (3) on a rigid support (40) carried by the mast and a portion of peripheral fabric (10). Said central zone (6) also of circular shape in this embodiment is arranged in a horizontal plane and is of dimension greater than the dimensions of the dome (7) which it overhangs. The peripheral fabric portion (10) extends outwards the central zone (6) of the fabric, said portion being able to be deployed or folded up under the action of the actuation and positioning means (MAP). The diameter of the fabric (2) is advantageously between 1.2 m and 5 m in order to isolate below a space (5) of sufficient size to allow several people to settle there.
Selon ce mode de réalisation, les moyens d'actionnement et de positionnement (MAP) sont constitués par une douille mobile de commande (11) disposée coulissante sur le mât porteur (3) et munie d'un faisceau de contre-baleines articulées (12), lesdites contre-baleines étant également articulées sur des baleines (13) disposées radialement sous la portion de toile périphérique (10). Lesdites baleines (13) sont articulées par rapport au mât porteur (3) juste sous le bord externe de la zone centrale (6) de la toile (2) sur le support rigide (40) et sont fixées à leur extrémité opposée sensiblement au bord externe (30) de la portion de toile périphérique (10) afin de pouvoir la tendre lorsque celle-ci est en position ouverte (A), comme le montrent les figures 2a et 2b. Il va de soi que la partie centrale (6) de la toile (2) pourrait avoir la forme d'un chapeau ou d'une calotte dont les bords externes seraient disposés de manière fixe dans un plan horizontal situé au-dessus de la coupole réfléchissante.According to this embodiment, the actuation and positioning means (MAP) consist of a movable control sleeve (11) slidingly disposed on the carrying mast (3) and provided with a bundle of articulated counter-whales (12 ), said counter-whales also being articulated on whales (13) arranged radially under the portion of peripheral fabric (10). Said whales (13) are articulated relative to the supporting mast (3) just under the outer edge of the central zone (6) of the fabric (2) on the rigid support (40) and are fixed at their opposite end substantially to the outer edge (30) of the portion peripheral fabric (10) so that it can be stretched when it is in the open position (A), as shown in Figures 2a and 2b. It goes without saying that the central part (6) of the fabric (2) could have the shape of a hat or a cap whose external edges would be fixedly arranged in a horizontal plane located above the dome. reflective.
Notons que l'élément de chauffage (8) est alimenté par des moyens d'alimentation (MA) correspondant au type d'élément de chauffage utilisé comme par exemple une bouteille de gaz, lesdits moyens d'alimentation (MA) étant avantageusement disposés dans une enceinte (14) du socle (4) du dispositif de chauffage (1). Par ailleurs, ledit socle comporte des moyens de déplacement (MD) tels que des roulettes, destinés à permettre le déplacement du dispositif (1). Notons que selon les modes de réalisation préférés du dispositif de chauffage pour terrasse (1), l'élément de chauffage (8) est un élément de chauffage radiant utilisant du gaz propane.Note that the heating element (8) is supplied by supply means (MA) corresponding to the type of heating element used, for example a gas cylinder, said supply means (MA) being advantageously arranged in an enclosure (14) of the base (4) of the heating device (1). Furthermore, said base comprises displacement means (MD) such as rollers, intended to allow movement of the device (1). Note that according to the preferred embodiments of the patio heater (1), the heater (8) is a radiant heater using propane gas.
Selon une variante de ce premier mode de réalisation illustrée figures 3a et 3b, le dispositif de chauffage pour terrasse est du type décrit précédemment avec un mât porteur (3) central muni de l'élément de chauffage (8), d'une coupole réfléchissante (7) et d'une toile (2). Selon cette variante, la coupole réfléchissante (7) disposée en dessous de la toile (2) est constituée par au moins deux portions de coupole (7a, 7b) mobiles par rapport au mât porteur (3) entre une position repliée (B) où lesdites portions sont disposées verticalement autour de l'élément de chauffage et une position ouverte (A) où lesdites portions sont assemblées de manière à former la coupole réfléchissante (7) qui est avantageusement légèrement au-dessus de l'élément de chauffage (8). Selon cette variante, l'assemblage des portions de coupole (7a, 7b) s'effectue également sous l'action des moyens d'actionnement et de positionnement (MAP) de la toile (2) avantageusement de façon simultanée. Ainsi, la position repliée desdites portions de coupole correspond avantageusement à la position fermée (B) de la toile et la position ouverte (A) desdites portions de coupole à celle de la position ouverte (A) de la toile. Pour ce faire, lesdites portions (7a, 7b) sont articulées sur le mât porteur (3) ou sur l'élément de chauffage (8) au niveau de leur extrémité supérieure et sont actionnées grâce à un système de contre-baleines complémentaires (15) solidaires desdites portions de coupole et articulées sur les baleines (13). Notons que, selon cette variante, les portions de coupole (7a, 7b) constituent avantageusement des moyens de protection de la toile (2) et plus précisément de la portion de toile périphérique (10) afin qu'elle ne se brûle pas lorsqu'elle passe de sa position ouverte à sa position fermée ou repliée. Pour ce faire, les portions de coupole peuvent comporter une face supérieure munie d'une couche de matériau isolant thermiquement.According to a variant of this first embodiment illustrated in FIGS. 3a and 3b, the patio heating device is of the type described above with a central support mast (3) provided with the heating element (8), with a reflecting dome (7) and a canvas (2). According to this variant, the reflective dome (7) disposed below the fabric (2) is constituted by at least two dome portions (7a, 7b) movable relative to the carrying mast (3) between a folded position (B) where said portions are arranged vertically around the heating element and an open position (A) where said portions are assembled so as to form the reflective dome (7) which is advantageously slightly above the heating element (8) . According to this variant, the assembly of the dome portions (7a, 7b) is also carried out under the action of the actuation and positioning means (MAP) of the fabric (2) advantageously simultaneously. Thus, the folded position of said dome portions advantageously corresponds to the closed position (B) of the fabric and the open position (A) of said dome portions to that of the open position (A) of the fabric. To do this, said portions (7a, 7b) are articulated on the support mast (3) or on the heating element (8) at their upper end and are actuated by a system of complementary counter-whales (15 ) integral with said dome portions and articulated on the whales (13). Note that, according to this variant, the dome portions (7a, 7b) advantageously constitute means for protecting the fabric (2) and more specifically the peripheral fabric portion (10) so that it does not burn when it goes from its open position to its closed or folded position. To do this, the dome portions may include an upper face provided with a layer of thermally insulating material.
Selon une autre variante d'exécution illustrée figures 4a, 4b et 4c, le dispositif est du type décrit précédemment, cependant, la coupole (7) formée par au moins deux portions de coupole (7a, 7b) mobiles est disposée de manière à s'assembler au-dessus des moyens d'isolation (MI) constitués par la toile (2). Notons que les portions de coupole sont solidaires des baleines (13) en rotation de manière à s'assembler lorsque les moyens d'actionnement et de positionnement (MAP) déploient la toile (2), comme le montre la figure 4a. Selon cette variante, la toile (2) comporte une ouverture (20) centrale à l'aplomb de la coupole (7).According to another alternative embodiment illustrated in FIGS. 4a, 4b and 4c, the device is of the type described above, however, the dome (7) formed by at least two movable dome portions (7a, 7b) is arranged so as to s 'Assemble above the insulation means (MI) constituted by the fabric (2). Note that the dome portions are integral with the ribs (13) in rotation so as to assemble when the actuation and positioning means (MAP) deploy the fabric (2), as shown in Figure 4a. According to this variant, the fabric (2) has a central opening (20) directly above the dome (7).
Il va de soi que la coupole pourrait être constituée par plus de deux portions de coupole sans pour autant sortir du champ de protection de l'invention. De même, l'assemblage desdites portions pourrait s'effectuer de manière différente en se superposant par exemple partiellement.It goes without saying that the dome could be constituted by more than two dome portions without going outside the protective field of the invention. Similarly, the assembly of said portions could be done differently by overlapping, for example partially.
Selon un deuxième mode de réalisation illustré figures 5a et 5b, le dispositif de chauffage pour terrasse (1) comporte un socle (4) sur lequel est monté le mât porteur (3) disposé de manière centrale en dessous de la toile (2) qui constitue les moyens d'isolation (MI) et portant dans sa partie supérieure l'élément de chauffage (8) et la coupole réfléchissante (7). La toile (2) est constituée par une portion de toile annulaire (16) destinée à être fixée directement sur le bord périphérique externe (17) de la coupole (7). La toile est destinée à être tendue par les moyens d'actionnement et de positionnement (MAP) qui comportent un faisceau de baleines (13) disposées sous la toile, articulées sur le bord périphérique externe (17) de la coupole (7) tandis que le bord de la portion de toile annulaire (16) est fixé à leur extrémité opposée. Les baleines (13) sont destinées à être commandées par un dispositif de contre-baleines (12) articulées sur une douille mobile de commande (11) du type de celle utilisée dans le premier mode de réalisation, montée coulissante sur le mât porteur (3) entre la coupole (7) et l'élément de chauffage (8), par exemple.According to a second embodiment illustrated in Figures 5a and 5b, the patio heating device (1) comprises a base (4) on which is mounted the support mast (3) arranged centrally below the fabric (2) which constitutes the insulation means (MI) and carrying in its upper part the heating element (8) and the reflective dome (7). The fabric (2) is constituted by a portion of annular fabric (16) intended to be fixed directly to the external peripheral edge (17) of the dome (7). The fabric is intended to be stretched by the actuation and positioning means (MAP) which include a bundle of ribs (13) arranged under the fabric, articulated on the external peripheral edge (17) of the dome (7) while the edge of the annular fabric portion (16) is fixed at their opposite end. The whales (13) are intended to be controlled by a device against the whales (12) articulated on a movable control socket (11) of the type used in the first embodiment, slidingly mounted on the carrying mast (3 ) between the dome (7) and the heating element (8), for example.
Notons que, selon une variante de ce deuxième mode de réalisation illustrée figures 6a et 6b, les contre-baleines (12) sont articulées directement sur le mât porteur (3), à l'extrémité supérieure de l'élément de chauffage (8), par exemple, tandis que la coupole (7) est mobile longitudinalement selon l'axe vertical (XX1) dudit mât porteur, ladite coupole étant, par exemple, montée sur une portion de tube (18) destinée à coulisser à l'intérieur d'un tube (19) constituant au moins la partie supérieure du mât porteur (3), des moyens de commande étant prévus de manière à provoquer le déplacement de la coupole (7) et ainsi l'ouverture ou la fermeture des baleines et de la toile. Selon une variante des différents modes de réalisation illustrée figure 7, la coupole réfléchissante (7) peut être disposée sensiblement à l'extrémité du mât porteur (3) central légèrement au-dessus du niveau où la toile (2) est portée par les baleines (13), la toile (2) comportant une ouverture circulaire (20) centrale à l'aplomb de la coupole (7).Note that, according to a variant of this second embodiment illustrated in FIGS. 6a and 6b, the counter-ribs (12) are articulated directly on the support mast (3), at the upper end of the heating element (8). , for example, while the dome (7) is movable longitudinally along the vertical axis (XX 1 ) of said carrying mast, said dome being, for example, mounted on a portion of tube (18) intended to slide inside a tube (19) constituting at least the upper part of the supporting mast (3), control means being provided so as to cause the displacement of the dome (7) and thus the opening or closing of the whales and the Web. According to a variant of the various embodiments illustrated in FIG. 7, the reflective dome (7) can be arranged substantially at the end of the central supporting mast (3) slightly above the level where the fabric (2) is carried by the whales (13), the fabric (2) having a circular opening (20) central to the base of the dome (7).
Selon un troisième mode de réalisation non représenté, le dispositif de chauffage pour terrasse ne comporte pas de coupole réfléchissante, mais les moyens de réflexion sont constitués par la toile elle-même dont la face interne dirigée vers le bas lorsqu'elle est déployée est réalisée en matière réfléchissante afin d'utiliser au maximum le rayonnement de l'élément de chauffage radiant disposé légèrement sous la toile pour chauffer l'air situé dans l'espace. Selon ce mode de réalisation, la toile utilisée peut par exemple être une toile aluminisée qui permet ainsi d'éviter au maximum la déperdition d'énergie en réfléchissant la majeure partie du rayonnement qu'elle reçoit vers l'espace (5) situé en dessousAccording to a third embodiment not shown, the patio heating device does not include a reflecting dome, but the reflecting means are constituted by the fabric itself, the internal face of which directed downwards when it is deployed is produced. in reflective material in order to make maximum use of the radiation from the radiant heating element placed slightly under the fabric to heat the air located in space. According to this embodiment, the canvas used can for example be an aluminized canvas which thus makes it possible to avoid as much as possible the loss of energy by reflecting the major part of the radiation which it receives towards the space (5) situated below.
Notons que selon les modes de réalisation du dispositif de chauffage pour terrasse et leurs variantes, les moyens de fixation de la toile (2) sur l'extrémité des baleines (13) ou sur une pièce solidaire du mât porteur (3) peuvent être avantageusement amovibles de manière à pouvoir enlever ladite toile (2). De ce fait, le dispositif de chauffage (1) peut comporter plusieurs toiles interchangeables et notamment une toile transparente destinée, d'une part, à empêcher l'air chaud de s'échapper de l'espace (5) où sont situés les utilisateurs, et d'autre part, à laisser passer les rayons du soleil afin de permettre aux dits utilisateurs de bronzer ou de profiter de leur lumière. Il peut également comporter une toile (2) non transparente, afin également de pouvoir être utilisé comme un parasol de type classique en été pour créer une zone d'ombre quand l'appareil est éteint. Par ailleurs, quel que soit le mode de réalisation du dispositif de chauffage, il comporte avantageusement un dispositif de commande destiné à commander l'allumage de l'élément de chauffage et son extinction. De même, il peut avantageusement comporter des moyens de réglage de l'élément de chauffage destinés à permettre de régler l'intensité du rayonnement qu'il produit et donc la température régnant dans l'espace (5). Notons que le dispositif de commande comporte avantageusement un système de sécurité, de manière à permettre l'extinction automatique des moyens de chauffage lorsque la toile quitte sa position ouverte. Ainsi, lorsque l'on replie la toile (2), l'élément de chauffage (8) est arrêté automatiquement de manière à éviter notamment tout risque de détérioration de ladite toile par brûlure au contact dudit élément. Selon le premier mode de réalisation, par exemple, le système de sécurité peut être constitué par un contacteur solidaire de la douille mobile de commande (11) destiné à couper l'alimentation de l'élément de chauffage radiant (8) dès que la douille mobile se déplace pour refermer la toile.Note that according to the embodiments of the patio heating device and their variants, the means of fixing the fabric (2) on the end of the whales (13) or on a part integral with the carrying mast (3) can advantageously be removable so as to be able to remove said canvas (2). Therefore, the heating device (1) may comprise several interchangeable fabrics and in particular a transparent fabric intended, on the one hand, to prevent hot air from escaping from the space (5) where the users are located. , and secondly, to let the sun's rays pass in order to allow the said users to sunbathe or take advantage of their light. It can also include a non-transparent canvas (2), so that it can also be used as a conventional type parasol in summer to create a shadow zone when the device is switched off. Furthermore, whatever the embodiment of the heating device, it advantageously comprises a control device intended to control the ignition of the heating element and its extinction. Likewise, it may advantageously include means for adjusting the heating element intended to make it possible to adjust the intensity of the radiation which it produces and therefore the temperature prevailing in the space (5). It should be noted that the control device advantageously includes a security system, so as to allow the automatic switching off of the heating means when the fabric leaves its open position. Thus, when the fabric (2) is folded, the heating element (8) is automatically stopped so as to avoid in particular any risk of deterioration of said fabric by burning on contact with said element. According to the first embodiment, for example, the security system can be constituted by a contactor integral with the movable control socket (11) intended to cut off the supply to the radiant heating element (8) as soon as the socket mobile moves to close the canvas.
Notons également que le système de sécurité comporte avantageusement un capteur du type thermocouple permettant d'arrêter l'alimentation de l'élément de chauffage radiant en cas d'incident. Il comporte également une veilleuse à contrôle d'atmosphère destinée à détecter les différents problèmes de l'élément de chauffage radiant liés à une mauvaise combustion du gaz, et notamment à éviter tout dégagement de monoxyde de carbone occasionné par une combustion incomplète de l'hydrocarbure.It should also be noted that the security system advantageously comprises a sensor of the thermocouple type making it possible to stop the supply of the radiant heating element in the event of an incident. It also includes an atmosphere control pilot light intended to detect the various problems of the radiant heating element linked to poor combustion of the gas, and in particular to avoid any release of carbon monoxide caused by incomplete combustion of the hydrocarbon. .
Les modes de réalisation et les variantes précédemment décrites du dispositif de chauffage pour terrasse comportent tous des moyens d'isolation (MI) constitués par une toile (2) destinée à prendre sensiblement une forme conique ouverte largement vers le bas ou une forme de chapeau, ladite toile (2) étant circulaire. Cependant, il va de soi que les dispositifs de chauffage pour terrasse pourraient comporter une toile destinée à prendre une forme différente. Ainsi, la toile pourrait être carrée, de manière à prendre une forme pyramidale, par exemple, sans pour autant sortir du champ de protection de l'invention. Notons toutefois que la surface de chauffe définie par la toile est avantageusement comprise entre 10 m 2 et 30 m 2 quelque soit la forme de la toile choisie. Toutefois, il est possible d'augmenter sensiblement la surface de chauffe en utilisant plusieurs éléments de chauffage dispersés sous la toile constituant les moyens d'isolation, ladite toile pouvant être de plus grande dimension comme par exemple posséder un diamètre de l'ordre de 7-8 mètres ou plus.The embodiments and variants described above of the patio heating device all include insulation means (MI) constituted by a fabric (2) intended to take substantially a conical shape open widely downwards or a hat shape, said fabric (2) being circular. However, it stands to reason that patio heaters could include a canvas designed to take a different shape. Thus, the canvas could be square, so as to take a pyramidal shape, for example, without going outside the protective field of the invention. Note, however, that the heating surface defined by the fabric is advantageously between 10 m 2 and 30 m 2 whatever the shape of the fabric chosen. However, it is possible to significantly increase the heating surface by using several heating elements dispersed under the fabric constituting the insulation means, said fabric being able to be of larger size such as for example having a diameter of the order of 7 -8 meters or more.
Notons, par ailleurs, que les moyens d'isolation (MI) peuvent être constitués non plus par une toile mais par un ou plusieurs éléments rigides ou semi-rigides destinés à former une surface d'isolation au dessus de l'élément de chauffage.Note, moreover, that the insulation means (MI) can no longer consist of a fabric but by one or more rigid or semi-rigid elements intended to form an insulation surface above the heating element.
Nous avons vu précédemment que les moyens d'isolation (MI) sont constitués par une coupole mobile entre deux positions, une position ouverte déployée (A) correspondant à la position d'utilisation, et une position fermée en position de rangement (B) selon laquelle la coupole est repliée pour être escamotée sensiblement verticalement le long du mât porteur (3).We have previously seen that the insulation means (MI) consist of a movable dome between two positions, an open deployed position (A) corresponding to the position of use, and a closed position in the storage position (B) according to which the dome is folded to be retracted substantially vertically along the carrier mast (3).
Aux figures 8a, 8b, 9a, 9b est illustré un mode de réalisation préféré de l'invention selon lequel la coupole de grande taille (38) constituant les moyens d'isolation (MI) est constituée de plusieurs éléments rigides (38a, 38b, 38c, 38d) en forme de secteurs de coupole. Chacun des secteurs est disposé articulé ou semi-rigide sur le mât porteur ou sur une pièce complémentaire solidaire du mat porteur.In FIGS. 8a, 8b, 9a, 9b is illustrated a preferred embodiment of the invention according to which the large dome (38) constituting the insulation means (MI) consists of several rigid elements (38a, 38b, 38c, 38d) in the form of dome sectors. Each of the sectors is arranged articulated or semi-rigid on the carrying mast or on a complementary piece integral with the carrying mast.
Notons que l'articulation de chacun des secteurs est réalisée avantageusement par un système à genouillères comprenant un ressort (400) permettant à l'ensemble des secteurs d'avoir deux positions stables, à savoir, la position fermée repliée (B) et la position ouverte d'utilisation (A). Ledit ressort (400) constitue les moyens d'actionnement et de positionnement (MAP) comme le montrent les figures 8a et 8b. Notons que, selon une variante illustrée figures 10a et 10b, les moyens d'actionnement et de positionnement (MAP) pourraient être constitués par un dispositif de douille mobile (11) et de contre-baleines (13), par exemple.Note that the articulation of each of the sectors is advantageously achieved by a toggle system comprising a spring (400) allowing all the sectors to have two stable positions, namely, the folded closed position (B) and the open use position (A). Said spring (400) constitutes the actuation and positioning means (MAP) as shown in FIGS. 8a and 8b. Note that, according to a variant illustrated in FIGS. 10a and 10b, the actuation and positioning means (MAP) could be constituted by a mobile bushing device (11) and against whales (13), for example.
Notons que le déploiement des éléments (38a, 38b, 38c, 38d) s'effectue en s'ouvrant comme une fleur, lesdits éléments se joignant par leurs bords latéraux ou se recouvrant partiellement afin d'obtenir une surface d'isolation pleine tel qu'illustré figure 9b. Selon ce mode de réalisation, la coupole de grande taille (38) constituant les moyens d'isolation peut également constituer les moyens de réflexion en possédant une face interne dirigée vers le bas réalisée en matériau réfléchissant.Note that the deployment of the elements (38a, 38b, 38c, 38d) is carried out by opening like a flower, said elements joining by their lateral edges or partially overlapping in order to obtain a full insulation surface such that 'illustrated in figure 9b. According to this embodiment, the large dome (38) constituting the insulation means can also constitute the reflection means by having an internal face directed downwards made of reflective material.
Selon ce mode de réalisation, la surface d'isolation constituée par la coupole de grande taille (38) est de forme circulaire, son diamètre étant avantageusement compris entre 1 et 5 mètres. Dans cette réalisation, les éléments rigides (38a, 38b, 38c, 38d) sont, par exemple, réalisés en tôle d'aluminium ou en matériau composite ou autre. Notons aussi que l'on pourrait n'avoir que trois éléments, ou plus de quatre éléments, sans pour autant sortir du cadre de l'invention. Ainsi, comme le montre, par exemple, une variante illustrée figures lia et 11b, la coupole de grande taille (38) est composée d'un grand nombre d'éléments rigides en forme de secteurs de coupole de faible largeur articulés sur un dispositif à douille mobile et contre-baleines. Bien entendu, dans cette réalisation, le dispositif de chauffage (1) est constitué par un mât porteur central (3) comportant à son extrémité supérieure (3a) un élément chauffant (8) surmonté de la coupole (38) et éventuellement d'une coupole réfléchissante (7).According to this embodiment, the insulation surface formed by the large dome (38) is circular, its diameter advantageously being between 1 and 5 meters. In this embodiment, the rigid elements (38a, 38b, 38c, 38d) are, for example, made of aluminum sheet or of composite or other material. Note also that one could have only three elements, or more than four elements, without departing from the scope of the invention. Thus, as shown, for example, in a variant illustrated in FIGS. 11a and 11b, the large dome (38) is composed of a large number of rigid elements in the form of small dome sectors hinged on a device mobile sleeve and counter whales. Of course, in this embodiment, the heating device (1) consists of a central support mast (3) comprising at its upper end (3a) a heating element (8) surmounted by the dome (38) and possibly by a reflective dome (7).
Selon plusieurs variantes d'exécution illustrées figures 12a à 15 et où pour plus de clarté, les organes décrits précédemment portent les mêmes références, le dispositif de chauffage pour terrasse comporte des moyens de maintien où le mât porteur (3) n'est pas disposé de manière centrale mais est déporté de manière à se trouver à l'extérieur de l'espace (5) situé à l'aplomb des moyens de chauffage (8) et de la toile ou de la coupole de grande taille lorsque celle-ci est en position ouverte. De ce fait, le dispositif de chauffage pour terrasse (1) présente une surface de chauffe disposée sous ses moyens d'isolation intégralement libre destinée aux utilisateurs, le mât porteur et son socle étant situés à l'extérieure de la surface de chauffe. Ainsi, selon une première variante, les moyens de maintien sont constitués par un socle muni d'une enceinte destinée à recevoir les moyens d'alimentation (4) tels qu'une bouteille de gaz ainsi que la ou les différente(s) toile(s) de rechange. Un mât porteur (25) monté sur le socle porte, de manière articulée, une poutre radiale (26) destinée à porter à son extrémité opposée un mât secondaire central (27) sur lequel sont disposés la toile, les moyens d'actionnement et de positionnement, les moyens de chauffage et la coupole réfléchissante. Notons que, selon cette variante, les moyens d'actionnement et de positionnement peuvent être obtenus de plusieurs manières différentes de type connu en soi. Notons également que, selon cette variante, la distance entre les mâts porteur et secondaire peut être réglée par des moyens de positionnement agissant, par exemple, sur la poutre radiale ou sur l'articulation entre la poutre et le mât porteur.According to several alternative embodiments illustrated in FIGS. 12a to 15 and where, for greater clarity, the members described above have the same references, the patio heater comprises holding means where the supporting mast (3) is not disposed centrally but is offset so as to be outside of the space (5) located directly above the heating means (8) and the large canvas or dome when the latter is in the open position. As a result, the patio heater (1) has a heating surface arranged beneath its completely free insulation means intended for users, the support mast and its base being located outside the heating surface. Thus, according to a first variant, the holding means consist of a base provided with an enclosure intended to receive the supply means (4) such as a gas bottle as well as the different fabric (s) ( s) spare. A supporting mast (25) mounted on the base carries, in an articulated manner, a radial beam (26) intended to carry at its opposite end a central secondary mast (27) on which the canvas, the actuating and positioning, the heating means and the reflective dome. Note that, according to this variant, the actuation and positioning means can be obtained in several different ways of a type known per se. Note also that, according to this variant, the distance between the supporting and secondary masts can be adjusted by positioning means acting, for example, on the radial beam or on the articulation between the beam and the supporting mast.
Selon cette variante et deux autres variantes illustrées figures 13a,According to this variant and two other variants illustrated in FIGS. 13a,
13b, 14a et 14b, montrant diverses solutions possibles d'articulation entre le mât secondaire central (27) et le mât porteur (25) tel qu'un système de treillis articulé (28) où un système à poutre radiale (29) montée pivotante, les moyens d'actionnement et de positionnement (MAP) peuvent avantageusement être commandés de manière automatique avec le dispositif de commande des mâts porteurs et secondaires. Ainsi, les moyens d'actionnement et de positionnement (MAP) sont actionnés par le déploiement du système d'articulation entre le mât secondaire et le mât central de manière simultanée grâce, par exemple, à un système de lien souple (31) liant un point fixe du mât porteur à une douille mobile (13).13b, 14a and 14b, showing various possible solutions for articulation between the central secondary mast (27) and the supporting mast (25) such as an articulated trellis system (28) or a radial beam system (29) pivotally mounted , the actuation and positioning means (MAP) can advantageously be controlled automatically with the device for controlling the supporting and secondary masts. Thus, the actuation and positioning means (MAP) are actuated by the deployment of the articulation system between the secondary mast and the central mast simultaneously thanks, for example, to a flexible link system (31) linking a fixed point of the supporting mast to a movable socket (13).
Lorsque le dispositif est déployé, l'utilisateur a accès aux moyens d'allumage de l'élément chauffant, ledit élément chauffant étant solidaire du mât secondaire et relié aux moyens d'alimentation par un gainage souple (32).When the device is deployed, the user has access to the ignition means of the heating element, said heating element being integral with the secondary mast and connected to the supply means by a flexible sheathing (32).
Notons également que les moyens de chauffage (MC) peuvent être constitués par plusieurs réglettes chauffantes (39), de type halogène par exemple, disposées sous la coupole de grande taille (38) ou la toileNote also that the heating means (MC) can be constituted by several heating strips (39), of halogen type for example, arranged under the large dome (38) or the fabric
(2) et/ou sur l'extrémité inférieure du mât secondaire par exemple comme le montre la figure 15.(2) and / or on the lower end of the secondary mast for example as shown in FIG. 15.
Par ailleurs, notons que dans les mode de réalisations comportant une toile et plusieurs portions de coupole, l'assemblage desdites portions de coupole peut s'effectuer grâce à des moyens d'actionnement propres indépendants des moyens d'actionnement de la toile et ne sont pas obligatoirement sollicités par les mêmes moyens d'actionnement.Furthermore, it should be noted that in the embodiments comprising a fabric and several dome portions, the assembly of said dome portions can be carried out by means of own actuation means independent of the actuation means of the fabric and are not not necessarily solicited by the same actuation means.
Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés à titre d'exemples, mais elle comprend aussi tous les équivalents techniques ainsi que leurs combinaisons. Of course, the invention is not limited to the embodiments described and shown by way of examples, but it also includes all the technical equivalents and their combinations.
