Definitions

• the present invention relates to a device for lighting a barbecue, a fireplace and a fire in general.
• the device according to the invention overcomes these drawbacks. It is characterized in that it is purchased ready-to-assemble and that it can be easily formed by the user from a plate of flammable material, preferably cardboard, pre-cut and grooved, thin and compact.
• the device comprises a hood-shaped grid and a fin burner.
• the grate consists of a ribbon of flammable pre-cut material, preferably in a spiral, and the fin burner is formed of inverted U or V surfaces and draws, in plan, a cross or a star.
• the grid is developed, vertically, on the burner and takes the form of a truncated cone of degrees or a truncated pyramid of degrees or any other volume flared down to the staircase profiles, without risers, according to the profiles of the burner serving as support.
• a central hole in the grate as well as notches or stops in the burner head allow their coupling and their stowage.
• the device thus formed is placed in a hearth before the fuel and allows the ignition below said crushed or cut fuel after ignition of the burner head.
• the device takes up, in the center of the hearth, the space usually occupied by an excess of fuel which is difficult to ignite and constitutes a flammable openwork structure in the form of a chimney hood.
• the burner at the heart of the hood, benefits for its combustion of the maximum draft and ignites, thanks to its fins, from the center to the periphery, the grate that it supports and the fuel placed above and on the sides.
• Light crushed fuels benefit from a particular advantage: the stacking of their pieces still retains a dome-shaped arrangement several minutes after the combustion of the device. This feature makes it possible to maintain self-ventilation at the heart of the fuel for longer; Manual ventilation is no longer essential and if you ventilate anyway, the combustion process is greatly accelerated.
• the device will not emit unpleasant odors: it is made of wood fibers and has no other charge than natural resin.
• FIG. 1 shows the pre-cut plate, plan view.
• FIG. 2 represents the constitution by folding of the burner seen from the side at 45 °.
• Figure 3 shows the burner, in cross, seen from the side at 45 °
• Figure 4 shows the disc of the grate, centered on the burner, seen from the side at 45 °.
• FIG. 5 represents the device, after development of the grate on the burner, seen from the side at 45 °.
• the device is characterized in that it is purchased in ready-to-assemble and that it can be formed by the user from a plate of flammable material precut and grooved (1) (fig.l).
• the device comprises a grid (2) in the form of an openwork hood, constituted by a ribbon of pre-cut flammable material, and a fin burner (3) with a cross or star plan, with triangular profiles, point at the top, or any other profiles whose base is wider than the top; the burner (3) is centered in the heart of the hood formed by the grate (2) (fig.5) and serves as a support, allowing the grate (2) not to deform too much under the weight of the fuel.
• the flammable material used for the manufacture of the precut plate (1), and used for the construction of the device is a cardboard, compact and flexible, rich in wood fibers and natural resins, preferably produced from resinous wood.
• This cardboard does not contain toxic fillers, such as synthetic glues, because it is the resin which serves as a link between the wood fibers;
• Another advantage: this type of cardboard gives off intense and prolonged heat when burned and stays incandescent for longer.
• the grid (2) can have, in plan, any contours and cutouts provided that its contours and cutouts form a ribbon and that this ribbon, once developed vertically, forms a hollowed-out and openwork volume whose base is more as wide as the top and fulfilling the function of hood.
• the grid (2) can therefore have a circular cutting plane (fig.l), elliptical, square, rectangular, cruciform, star or other and constitute, once developed vertically: a truncated cone (fig.5), an elliptical truncated cone, a pyramid trunk, an elongated pyramid trunk, a cruciform or star pyramid trunk and any other step volume, flared down, narrower up.
• the grid (2) is at the start a disc (fig.l and fig 4) precut in a spiral or in concentric circles connected together by a ribbon of material in S (4), diagonally or otherwise, and which automatically forms a grid (2) in the form of an apertured frustoconical hood when this precut disc (2), centered on the burner, is developed downwards, vertically, by the user (fig 5).
• the grid (2) has a central hole (S) in which the head (6) of the burner (3) is adapted, this hole (5) tends to favor the draft and the evacuation of the fumes during combustion.
• the central hole (5) of the grid (2) comprises an articulated flap (7) resulting from the partial cutting of this hole and being able to straighten vertically before or during the penetration of the head (6 ) from the burner (3) to the center of the grate (2) (fig.5).
• This articulated flap (7) if it is properly oriented, protects the ignition flame from the wind and also serves, when it is in flames or incandescent, to ignite the gases which would escape without burning; thus prevents the fire from smothering and the cardboard from burning too slowly.
• the fin burner (3) consists of a single piece (fig. 2 and 3), starting from the peripheral zone (3) (fig.l) of the pre-cut material plate (1); its inverted U or N profiles as well as its cross or star shape are obtained thanks to folds made in hollow or in bump along the diagonals and the medians according to pre-existing grooves (8 and 9) (fig.1 , 2 and 3) ..
• the fin burner (3) consists of inverted U or N plates or flying buttresses or arches assembled in a cross or in a star, using notches, according to a male-female assembly; these plates are taken from the corners of the pre-cut flammable material plate.
• the head (6) of the burner (3) comprises notches or notches (10) allowing the stowage in abutment or by snap-fastening of the grate (2) to the burner (3) after intrusion of the head (6) of the burner (3 ) in the central hole (5) of the grid (2).
• the head (6) of the burner (3) has one or more holes (11) in which one or more match heads can be housed for firing.
• the best way to carry out the invention is characterized by the choice of a plate of flammable material (1) made of woodboard produced from resinous wood.
• the cardboard-wood plate (1) is square (fig.l) and pre-cut into two parts: a central disc-shaped part (2) and a second peripheral part with a circular internal contour and a square external contour (3).
• the peripheral part (3) (fig.l) will be used to make a fin burner (3) (fig.2 and 3), in one piece, thanks to intaglio folds according to the medians and folds in bump along the diagonals from predetermined grooves (8 and 9).
• the disc (2) is precut in a spiral or concentric circles linked together by an S-shaped turn (4) and has about six turns, it will constitute the frustoconical grid (2) intended to serve as a hood when it is centered on the burner (fig.4) and developed vertically downwards by the user (fig.5).
• the grid (2) has a circular central hole (5) in which the head (6) of the burner (3) fits; this gap (5) tends to favor the draft and the evacuation of smoke.
• the central hole (5) of the grid (2) comprises a circular articulated flap (7) resulting from the partial cutting of this hole (5) and which can straighten vertically (fig. 4 and 5) before or during penetration from the head (6) of the burner (3) to the center of said grid (2).
• the head (6) of the burner (3) has notches at right angles (10) allowing the stopping of the grid (2) in abutment with the burner (3).
• the head (6) of the burner (3) has holes (11), originally located in the corners of the cardboard-wood plate (fig.l), in which the heads of the matches can be accommodated for setting fire.
• the cardboard-wood plate (1) has the dimensions 24 cm x 24 cm x 0.125 cm
• the disc or grate (2) has a diameter of 18 cm
• the burner (3) has a height of 10 cm and a wingspan identical to the grid (2)
• the central hole (5) of the grid (2) has a diameter of 3.5 cm identical to that of the articulated flap (7) and that of the head (6) of the burner (3) whose holes (11) for ignition are of a diameter of 1.2 cm
• the fire starter, once shaped (fig. 5) will have dimensions of about 11 cm for its height, 18 cm for its diameter at the base.
• the width of each of the 6 turns of the grid (2) is 1.2 cm.
• the device according to the invention is intended for a very wide public and must be produced in large series, industrially; the raw material and the techniques for the production of the invention exist: the cardboard-wood is manufactured in several countries including France and the cutting of the plates is done from cardboard rolls thanks to "forms" of cutting mounted on presses.
