Description

La présente invention se rapporte à un appareil lumineux portatif de signalisation nocturne.The present invention relates to a portable luminous device for night signaling.

Il est connu (voir brevet US-A-4 319 309) un appareil portatif de signalisation nocturne composé d'au moins une source lumineuse contenue dans une enveloppe protectrice caractérisé par des moyens pour faire émettre par l'appareil de la lumière rouge ou de la lumière jaune et de la lumière blanche d'éclairage normal et moyens pour attacher l'appareil à la personne en le fixant en n'importe quelle partie de la personne ou d'un support et pour le saisir.It is known (see US Pat. No. 4,319,309) a portable night signaling device composed of at least one light source contained in a protective envelope characterized by means for causing the device to emit red light or yellow light and white light normal lighting and means for attaching the apparatus to the person by fixing it in any part of the person or a support and for grasping it.

Le brevet FR-A-860 720 se refère à un appareil selon le brevet U.S.A. sous indiqué, comprenant aussi des dispositifs pour accumuler l'énergie de la batterie alimentant la source lumineuse pendant son extinction due à l'intermittence, et la restituer pendant l'illumination.The patent FR-A-860 720 refers to an apparatus according to the patent USA indicated below, also comprising devices for accumulating the energy of the battery supplying the light source during its extinction due to intermittence, and restoring it during the 'illumination.

Les brevets: GB-A-1 337 217, CH-A-357 466, U.S.-A-4210953 concernent des détails de construction et d'utilisation d'appareils lumineux portatifs de signalisation nocturne.The patents: GB-A-1 337 217, CH-A-357 466, U.S.-A-4210953 relate to details of the construction and use of portable night light signaling devices.

L'appareil selon la présente invention diffère des appareils connus en ce que il est caractérisé par un accumulateur électrique disposé en parallèle à la batterie et par une source lumineuse auxiliaire ayant une puissance électrique plus grande de celle de la source lumineuse normale afin de compenser le baisse de luminosité due à l'intermittente.The apparatus according to the present invention differs from the known apparatuses in that it is characterized by an electric accumulator arranged in parallel with the battery and by an auxiliary light source having an electric power greater than that of the normal light source in order to compensate for the decrease in brightness due to intermittent.

  • Figure 5 shows how to block the protective plate of the device;
  • Figure 6 is the electrical diagram of the complete device, compressing the accumulator and the auxiliary light source.

En référence aux figures, l'appareil comprend une enveloppe antérieure 1 transparente colorée en rouge et une plaquette postérieure transparente 2 incolore ou colorée en jaune. Ces deux parties sont établies en matière artificielle plastique, acrylique ou en matière équivalente. A l'enveloppe 1 se raccordent quatre parois latérales 4,5, 6 et 7 de même épaisseur entre elles.With reference to the figures, the apparatus comprises a transparent front envelope 1 colored in red and a transparent rear plate 2 colorless or colored in yellow. These two parts are made of plastic, acrylic or equivalent artificial material. To the casing 1 are connected four side walls 4,5, 6 and 7 of the same thickness between them.

Vers le haut, selon le dessin, on a prévu dans l'enveloppe deux pattes parallèles 8 et 9 de faible longueur disposées à 90° par rapport à la paroi antérieure pour le blocage de la partie filetée d'une lampe 10. Ces pattes 8 et 9 sont de faible épaisseur pour permettre l'insertion à force entre elles de la lampe 10. Elles sont solidaires jusqu'à un certain point de la paroi antérieure 3 et par conséquent rendues flexibles élastiquement et transversalement par rapport à la paroi antérieure.Upwards, according to the drawing, there are provided in the envelope two parallel legs 8 and 9 of short length arranged at 90 ° relative to the front wall for blocking the threaded part of a lamp 10. These legs 8 and 9 are thin to allow the forced insertion between them of the lamp 10. They are integral to a certain point with the front wall 3 and therefore made flexible elastically and transversely to the front wall.

Dans l'intervalle d, délimité par les bords supé- reurs la 8', 9' desdites pattes 8, 9 et par la face de la paroi transversale supérieure 5 peuvent être insérées avec frottement deux lamelles 11 et 12 en métal pour réaliser le contact entre la lampe 10 et une série de deux piles 13. et 14 de forme allongée cylindrique. Ces piles peuvent s'introduire par pression élastique entre les pattes déjà mentionnées de faible longueur 8 et respectivement 9 d'une part et d'aurte part la face intérieure des parois latérales correspondantes 4 et 6.In the interval d, delimited by the upper edges la 8 ′, 9 ′ of said legs 8, 9 and by the face of the upper transverse wall 5 can be inserted with friction two metal strips 11 and 12 to make contact between the lamp 10 and a series of two batteries 13. and 14 of elongated cylindrical shape. These stacks can be introduced by elastic pressure between the legs already mentioned of short length 8 and respectively 9 on the one hand and on the other hand the inner face of the corresponding side walls 4 and 6.

Pour réaliser une retenue optimale des lamelles mentionnées 11 et 12, on a prévu que de la face intérieure de la paroi transversale supérieure 5 dépassant des nervures 15 et 16 qui reproduisent les rainures établies sur les lamelles correspondantes 11 et 12 (figure 3).To achieve optimum retention of the lamellae mentioned 11 and 12, provision has been made only for the inner face of the upper transverse wall 5 projecting from ribs 15 and 16 which reproduce the grooves established on the corresponding lamellae 11 and 12 (FIG. 3).

Parallèlement à la paroi transversale inférieure 7 de l'enveloppe 1 existe une paroi séparatrice 17 contre laquelle avec l'interposition d'une série de deux autres lamelles de métal 18 et 19 trouvent appui les contacts correspondants des deux piles 13 et 14 disposées en serie pour former une batterie. De façon analogue comme on l'a prévu pour les pattes 8 et 9 la cloison séparatrice 17 est mince afin de présenter une certaine souplesse dans la direction transversale en assurant ainsi une retenue efficace des deux batteries.Parallel to the lower transverse wall 7 of the casing 1 there exists a separating wall 17 against which, with the interposition of a series of two other metal strips 18 and 19, bear the corresponding contacts of the two batteries 13 and 14 arranged in series to form a battery. Likewise, as provided for the legs 8 and 9, the separating partition 17 is thin so as to have a certain flexibility in the transverse direction, thus ensuring effective retention of the two batteries.

Avantageusement, l'enveloppe est établie en un pièce unique.Advantageously, the envelope is established in a single piece.

Un commutateur 20 est prévu pour glisser dans une ouverture 21 ménagée dans la base inférieure du boîtier pour établir ou couper le contact électrique entre la batterie et la lampe. En variante, on peut prévoir un commutateur qui permette d'alimenter la lampe 10 à tension constante (lumière continue) ou, au moyen d'un interrupteur bimétallique 28 (Fig. 6) non représenté en fig. 3 de type connu, pour lumière intermittente. Dans la paroi transversale supérieure 5 de l'enveloppe est ménagée transversalement une fente pour le guidage et le passage d'un ruban 22 ou d'une bande convenable en tissu résistant.A switch 20 is provided for sliding in an opening 21 formed in the lower base of the housing to establish or cut the electrical contact between the battery and the lamp. As a variant, a switch can be provided which makes it possible to supply the lamp 10 at constant voltage (continuous light) or, by means of a bimetallic switch 28 (FIG. 6) not shown in FIG. 3 of known type, for intermittent light. In the upper transverse wall 5 of the envelope is formed transversely a slot for guiding and passing a ribbon 22 or a suitable strip of resistant fabric.

Ce dernier ruban, au moyen d'un nombre approprié de trous 23, ménagés dans lui, peut être bloqué par rapport à l'appareil (figure 4). A cet effet, à l'intérieur de l'enveloppe 1, une appendice 24 s'étend perpendiculairement à partir de la paroi frontale antérieure 3.This last strip, by means of an appropriate number of holes 23, formed in it, can be blocked relative to the device (Figure 4). To this end, inside the envelope 1, an appendage 24 extends perpendicularly from the front front wall 3.

Dans l'appendice est pratiqué un trou fileté 25. Avec l'emploi d'une vis spéciale 26, pourvue d'un épaulement 26' et d'une tête 26", le ruban 22 est replié pour former un brassard ou bien pour se serrer autour de la taille en supportant l'appareil.In the appendix is made a threaded hole 25. With the use of a special screw 26, provided with a shoulder 26 'and a head 26 ", the ribbon 22 is folded up to form an armband or else to tighten around the waist while supporting the device.

Comme le montre la figure 5, en plus de servir à bloquer le ruban, la vis sert à la fixation de la plaquette de fermeture 2 de l'enveloppe sur sa face arrière. Cette plaquette, quand le boîtier est de couleur rouge, est réalisée avantageusement en matière colorée en jaune ou incolore si on veut avoir de la lumière jaune de préférence intermittente qui signale un danger ou de la lumière blanche s'il y a lieu d'éclairer fortement les objetcts.As shown in Figure 5, in addition to serving to block the tape, the screw is used to fix the closure plate 2 of the envelope on its rear face. This plate, when the housing is red, is advantageously made of yellow or colorless material if you want to have yellow light, preferably intermittently tent that signals a danger or white light if there is reason to strongly illuminate objects.

Avantageusement, la paroi antérieure 3 présente centralement une épaisseur réduite 3' en étant lisse pour un passage majoré de lumière tandis que le reste de la surface translucide de l'enveloppe est établi avec une surface de préférence durcie ou avec moletage fin et régulier par exemple d'une épaisseur de 2 mm.Advantageously, the front wall 3 has a reduced thickness 3 ′ centrally, being smooth for an increased passage of light, while the rest of the translucent surface of the envelope is established with a surface preferably hardened or with fine and regular knurling for example. with a thickness of 2 mm.

On a prévu que l'enveloppe 1 et la plaquette 2 peuvent être transparentes et incolores tandis qu'à l'intérieur sont logées deux lampes colorées comprenant une rouge l'autre jaune avec une lampe non colorée.Provision has been made for the envelope 1 and the plate 2 to be transparent and colorless while inside are housed two colored lamps comprising one red and the other yellow with an uncolored lamp.

Après avoir réalisé l'appareil et effectué les mesures électriques on a trouvé que avec deux piles 13 et 14 de 1,5 volts chacune, disposée en série et avec une lampe 10 d'environ 1 Watt (Fig. 6), le courant, après fermeture de l'interrupteur 20 et de l'interrupteur bimétallique 28, est de 0,35 ampères, tandis que après la mise en fonction de l'interrupteur bimétallique 28 il baisse a une valeur moyenne de 0,2 ampères, pendant 0,5 secondes (éclairage) suivie d'une extinction pendant 1 seconde (période=1,5 secondes).After having carried out the apparatus and carried out the electrical measurements it was found that with two batteries 13 and 14 of 1.5 volts each, arranged in series and with a lamp 10 of approximately 1 Watt (Fig. 6), the current, after closure of the switch 20 and of the bimetallic switch 28, is 0.35 amperes, while after the activation of the bimetallic switch 28 it drops to an average value of 0.2 amperes, for 0, 5 seconds (lighting) followed by switching off for 1 second (period = 1.5 seconds).

Cela signifie que l'intensité lumineuse de la lampe 10 se réduit au 57% de sa valeur normale à cause de la mise en fonction de l'interrupteur bimétallique 28.This means that the light intensity of the lamp 10 is reduced to 57% of its normal value due to the activation of the bimetallic switch 28.

Pour éviter l'inconvenient, selon la présente invention, on dispose, en parallèle de la batterie des piles 13, 14 et enstallées dans l'espace vide 31 (fig. 3) de l'appareil, un petit accumulateur 27 (fig. 6) et une deuxième lampe 30 (lampe auxiliaire) dont le filament peut supporter un courant

Figure imgb0001
To avoid the inconvenience, according to the present invention, there is, in parallel with the battery of the batteries 13, 14 and installed in the empty space 31 (fig. 3) of the apparatus, a small accumulator 27 (fig. 6 ) and a second lamp 30 (auxiliary lamp) whose filament can support a current
Figure imgb0001

L'accumulateur se charge pendant la période d'extinction de la lampe 30 (1 seconde), et se décharge, aidant la batterie 13, 14 pendant la période d'éclairage de la lampe 30 (0,5 sécondes) en livrant ainsi le courant de 0,6 ampères requise.The accumulator charges during the lamp 30 off period (1 second), and discharges, helping the battery 13, 14 during the lamp 30 illumination period (0.5 seconds) thereby delivering the 0.6 amp current required.

L'accumulateur doit pourtant livrer (0,6-0,2) =0,4 ampères pendant 0,5 secondes.However, the accumulator must deliver (0.6-0.2) = 0.4 amps for 0.5 seconds.

Sa capacité est donc de 0,2 ampères-seconde et son poids d'environ 1 gramme! Il est donc parfaitement plaçable avec la lampe auxiliaire 30, dans l'endroit libre 31 (fig. 3) de l'appareil.Its capacity is therefore 0.2 ampere-seconds and its weight around 1 gram! It is therefore perfectly placed with the auxiliary lamp 30, in the free place 31 (fig. 3) of the device.

L'emploi d'un condensateur au lieu d'un accumulateur n'est pas possible, vue la tension très basse disponible (3 volts), puisque l'énergie absorbée par un condensateur est fonction du carré de la tension.The use of a capacitor instead of an accumulator is not possible, given the very low voltage available (3 volts), since the energy absorbed by a capacitor is a function of the square of the voltage.
