Description

La présente invention a pour objet une lampe de lecture portative qui puisse par exemple être fixée aisément sur un livre ou un dossier et qui soit suffisamment légère pour ne pas incommoder le lecteur. En outre, cette lampe est réglable suivant plusieurs directions de sorte que le lecteur puisse la positionner en fonction de la façon dont il tient le livre pour avoir toujours un bon éclairage. Enfin, cette lampe doit être autonome et donc comporter une propre source d'alimentation pour ne pas être tributaire d'une prise électrique.Cette lampe doit en outre être peu encombrante et pliable de manière à pouvoir se ranger dans un faible volume pour permettre de l'emporter dans un bagage.The present invention relates to a portable reading lamp which can for example be easily fixed to a book or a folder and which is light enough not to inconvenience the reader. In addition, this lamp is adjustable in several directions so that the reader can position it according to the way he holds the book to always have good lighting. Finally, this lamp must be autonomous and therefore have its own power source so as not to be dependent on an electrical outlet. This lamp must also be compact and foldable so that it can be stored in a small volume to allow take it in luggage.

Il existe des lampes de lecture portatives qui notamment peuvent se fixer à la tête d'un lit ou sur un livre à l'aide d'une pince, toutefois ces modèles sont généralement lourds et encombrants.There are portable reading lamps which in particular can be fixed to the head of a bed or on a book using a clamp, however these models are generally heavy and bulky.

La demande de brevet français publiée No 2.541.754 divulgue une lampe portative légère présentant plusieurs degrés de liberté pour son réglage mais ayant l'inconvénient de ne pas pouvoir se plier dans un faible volume en position de non utilisation et surtout de ne pas permettre le réglage de la distance entre l'ampoule et la surface de lecture éclairée.The published French patent application No. 2,541,754 discloses a light portable lamp having several degrees of freedom for its adjustment but having the disadvantage of not being able to bend in a small volume in the non-use position and especially of not allowing the adjustment of the distance between the bulb and the illuminated reading surface.

La présente invention a pour objet une lampe de lecture portative tendant à obvier aux inconvénients précités qui se distingue par le fait qu'elle comporte un pied présentant des moyens de fixation rapides sur un objet; un bras télescopique dont la partie inférieure est articulée suivant un axe perpendiculaire à l'axe longitudinal du pied sur ledit pied, et dont la partie supérieure coulisse sur cette partie inférieure, et un abat-jour articulé sur l'extrémité libre de la partie supérieure du bras télescopique, suivant un axe parallèle à l'axe de pivotement de la partie inférieure du bras sur le pied, cet abat-jour renfermant une douille destinée à recevoir une ampoule, raccordée à un cordon d'alimentation.The present invention relates to a portable reading lamp tending to obviate the aforementioned drawbacks which is distinguished by the fact that it comprises a foot having quick fixing means on an object; a telescopic arm whose lower part is articulated along an axis perpendicular to the longitudinal axis of the foot on said foot, and whose upper part slides on this lower part, and a lampshade articulated on the free end of the upper part the telescopic arm, along an axis parallel to the pivot axis of the lower part of the arm on the foot, this lampshade containing a socket intended to receive a bulb, connected to a power cord.

Le dessin annexé illustre schématiquement et à titre d'exemple un forme d'exécution de la lampe de lecture portative.The attached drawing illustrates schematically and by way of example an embodiment of the portable reading lamp.

  • La figure 8 est une vue partielle, en coupe à plus grande échelle de l'abat-jour et de la partie supérieure du bras de la lampe.Figure 8 is a partial view, in section on a larger scale of the lampshade and the upper part of the lamp arm.

Dans la forme d'exécution illustrée la lampe de lecture portative comporte un étui 1 muni d'un couvercle à charnière dans lequel sont logés, pour leur rangement et leur transport, la lampe 3 proprement dite, des piles ou accumulateurs 4 d'alimentation, ainsi qu'un adaptateur 5 permettant soit l'alimentation directe de la lampe basse tension à partir du réseau de distribution électrique soit la recharge des accumulateurs.In the illustrated embodiment, the portable reading lamp comprises a case 1 provided with a hinged cover in which are housed, for their storage and transport, the lamp 3 proper, batteries or accumulators 4 of supply, as well as an adapter 5 allowing either the direct supply of the low voltage lamp from the electrical distribution network or the recharging of the accumulators.

Les piles ou accumulateurs 4 sont disposés dans un compartiment 6 de l'étui 1,2 qui est obturé par un couvercle amovible 7 dont une partie 7a est repliable pour permettre l'échange des piles 4 sans enlever complètement ce couvercle 7.The batteries or accumulators 4 are arranged in a compartment 6 of the case 1,2 which is closed by a removable cover 7 of which a part 7a is foldable to allow the exchange of batteries 4 without completely removing this cover 7.

Les parois latérales de l'étui 1 sont légèrement coniques pour permettre leur démontage et la face terminale 8 de cet étui 1 comporte des nervures 9 d'épaisseur croissante constituant des pieds permettant de poser l'étui sur une surface horizontale en position verticale comme illustré à la figure 3.The side walls of the case 1 are slightly conical to allow their disassembly and the end face 8 of this case 1 has ribs 9 of increasing thickness constituting feet allowing the case to be placed on a horizontal surface in a vertical position as illustrated in Figure 3.

Cet étui 1, 2 comporte encore une rainure 10 présentant en section transversale la forme d'une queue d'aronde, pratiquée dans son fond et s'étendant parallèlement aux grands côtés de ce fond. Comme on le verra plus loin cette rainure 10 permet la fixation de la lampe sur l'étui qui forme alors un socle ou support pour celle-ci.This case 1, 2 also has a groove 10 having in cross section the shape of a dovetail, formed in its bottom and extending parallel to the long sides of this bottom. As will be seen later this groove 10 allows the fixing of the lamp on the case which then forms a base or support for the latter.

Enfin, la face libre 11 du compartiment 6 recevant les piles ou accumulateurs 4 comporte une prise (non illustrée) raccordée de façon connue auxdites piles, destinée à coopérer soit avec une fiche 12 connectée & l'extrémité d'un cordon d'alimentation 13 de la lampe 3 soit à une fiche 14 connectée a l'extrémité d'un fil 15 sortant de l'adaptateur 5.Finally, the free face 11 of the compartment 6 receiving the batteries or accumulators 4 comprises a socket (not shown) connected in a known manner to said batteries, intended to cooperate either with a plug 12 connected to the end of a power cord 13 of the lamp 3 or to a plug 14 connected to the end of a wire 15 coming out of the adapter 5.

La lampe 3 proprement dite est formée d'un pied 16 muni de moyens de fixation sur un support, un bras télescopique 17,18 et un abat-jour 19.The lamp 3 proper is formed of a foot 16 provided with means of attachment to a support, a telescopic arm 17, 18 and a lampshade 19.

Le pied 16 de la lampe est venu d'une pièce de fabrication, par moulage, avec la partie inférieure 17 du bras télescopique de la lampe. Une charnière plastique 22, constituée par un affaiblissement de la matière, s'étendant perpendiculairement à l'axe longitudinal x-x du pied 16 permet un pivotement du bras 17,18 par rapport au pied d'une position pour laquelle la partie inférieure 17 du bras se trouve dans le prolongement du pied jusque dans une position pour laquelle la partie inférieure 17 du bras est repliée contre la face supérieure du pied.The foot 16 of the lamp came from a workpiece, by molding, with the lower part 17 of the telescopic arm of the lamp. A plastic hinge 22, formed by a weakening of the material, extending perpendicular to the longitudinal axis xx of the foot 16 allows the arm 17,18 to pivot relative to the foot from a position for which the lower part 17 of the arm is in the extension of the foot into a position for which the lower part 17 of the arm is folded against the upper face of the foot.

Ce pied comporte à son extrémité arrière, proche de la charnière 22 le reliant à la partie inférieure 17 du bras, deux saillies pyramidales 20 dont les faces externes sont situées chacune dans une des faces latérales du pied et dont les faces internes coopèrent avec les faces externes de deux tétons 21 de la partie inférieure 17 du bras. Ces tétons 21 comportent des faces biseautées 2la pour guider leur entrée en contact avec les faces internes des saillies 20. La friction entre ces tétons 21 et les faces internes des saillies 20 est suffisante pour permettre d'immobiliser le bras 17,18 dans une position angulaire choisie par le lecteur.This foot comprises at its rear end, close to the hinge 22 connecting it to the lower part 17 of the arm, two pyramidal projections 20 whose external faces are each located in one of the lateral faces of the foot and whose internal faces cooperate with the external faces of two pins 21 of the lower part 17 of the arm. These pins 21 have beveled faces 2la to guide their entry into contact with the internal faces of the projections 20. The friction between these pins 21 and the internal faces of the projections 20 is sufficient to allow the arm 17,18 to be immobilized in a position angle chosen by the reader.

Des passages 24a pratiqués dans le pied 16 donnent passage aux tétons 21 pour permettre de rabattre complètement le bras 17,18 contre le pied 16.Passages 24a made in the foot 16 give passage to the pins 21 to allow the arm 17, 18 to be completely folded against the foot 16.

Le pied 16 comporte encore des moyens de fixation sur un support telle la page de couverture d'un livre par exemple. Ces moyens de fixation sont constitués dans cette forme d'exécution par déux lames inférieures 23, situées dans un même plan mais séparées l'une de l'autre, encastrées chacune par leur extrémité arrière dans une des saillies 20. Ces moyens de fixation comportent encore une lame supérieure 24 dont l'extrémité arrière est solidaire des deux saillies 20. Cette lame supérieure 24 est légèrement plus large que l'espace libre entre les lames inférieures 23 et recouvre celui-ci. La face inférieure de cette lame supérieure 24 est située dans un plan approximativement parallèle au plan contenant les faces supérieu- res des lames inférieures 23, une butée 25 solidaire de la lame supérieure 24 entre normalement en contact avec les faces supérieures des lames inférieures 23. Grâce à l'élasi- ticité propre de la lame 24 et/ou des lames 23 on a ainsi réalisé une pince ou trident élastique pouvant s'enfiler sur la couverture d'un livre et pincer celle-ci suffisamment fort pour maintenir la lampe dans la position choisie par le lecteur.The stand 16 also includes means for fixing to a support such as the cover page of a book for example. These fixing means are constituted in this embodiment by two lower blades 23, located in the same plane but separated from each other, each embedded by their rear end in one of the projections 20. These fixing means comprise another upper blade 24, the rear end of which is integral with the two projections 20. This upper blade 24 is slightly wider than the free space between the lower blades 23 and covers it. The underside of this outer cutter 24 is located in a plane approximately parallel to the plane containing the upper faces of the lower blades 23, 25 a stop integral with the upper blade 24 normally comes in contact with the upper faces of the lower blades 23. Thanks to the inherent elasticity of the blade 24 and / or of the blades 23, an elastic clamp or trident has thus been produced which can be threaded over the cover of a book and pinch it sufficiently hard to hold the lamp in the position chosen by the reader.

La partie inférieure 17 du bras 17,18 de la lampe présente en majeure partie une forme tubulaire de section carrée ou rectangulaire dont les dimensions extérieures correspondent aux dimensions intérieures de la partie supérieure 18 de ce bras de manière à pouvoir coulisser avec frottement dans celle-ci. Ainsi la longueur du bras 17,18 peut être modifiée à volonté par le lecteur, la friction entre les deux parties 17,18 étant suffisante pour assurer le maintien de ces parties dans la position choisie par l'utilisateur.The lower part 17 of the arm 17, 18 of the lamp has for the most part a tubular shape of square or rectangular section whose external dimensions correspond to the internal dimensions of the part su 18 of this arm so that it can slide with friction therein. Thus the length of the arm 17,18 can be modified at will by the reader, the friction between the two parts 17,18 being sufficient to ensure the maintenance of these parts in the position chosen by the user.

La partie supérieure 18 du bras télescopique est venue d'une pièce de moulage avec l'abat-jour 19 et ces pièces sont reliées par une charnière plastique 30. Cette charnière plastique s'étend parallèlement à la charnière plastique 22. Les faces internes 31 des projections arrières 25 frottent contre les faces latérales 26 de la partie supérieure 18 du bras télescopique pour permettre de fixer la position relative de l'abat-jour sur le bras comme désiré par l'utilisateur. Des plans inclinés 27 à l'extrémité des extensions arrières 25 assurent un engagement doux et progressif entre ces pièces et la partie supérieure 18 du bras,The upper part 18 of the telescopic arm came from a molding part with the lampshade 19 and these parts are connected by a plastic hinge 30. This plastic hinge extends parallel to the plastic hinge 22. The internal faces 31 rear projections 25 rub against the side faces 26 of the upper part 18 of the telescopic arm to allow the relative position of the lampshade to be fixed on the arm as desired by the user. Inclined planes 27 at the end of the rear extensions 25 ensure a smooth and progressive engagement between these parts and the upper part 18 of the arm,

Une douille, non illustrée, est montée dans l'abat-jour pour recevoir une ampoule 28 alimentée en courant: électrique à basse tension par le cordon 1.3.A socket, not shown, is mounted in the lampshade to receive a bulb 28 supplied with current: low voltage electric by the cord 1.3.

Lorsque la lampe n'est pas utilisée elle est rangée dans son étui, le bras télescopique 17, 18 est raccourci au maximum, le pied 16 rabattu contre la partie inférieure 17 du bras et l'abat-jour 19 étendu dans le prolongement de la partie supérieure 18 du bras.When the lamp is not in use, it is stored in its case, the telescopic arm 17, 18 is shortened as much as possible, the foot 16 folded against the lower part 17 of the arm and the lampshade 19 extended in the extension of the upper part 18 of the arm.

Le dos de la partie supérieure 18 du bras présente une formation mile 32 de section transversale en queue d'aronde destinée à coopérer avec la rainure 10 de l'étui.The back of the upper part 18 of the arm has a mile formation 32 of dovetail cross section intended to cooperate with the groove 10 of the case.

Ainai lorsque l'étui 1 est plac4 en position verticale (figure 3) la lampe peut y être fixée par l'introduction de la formation 32 dans la rainure 10 de manière à réaliser une lampe de table portative. Dans cette position, le pied 16 est rabattu contre la partie inférieure 17 du bras. Dans une variante la formation femélle peut être constituée par une ouverture pratiquée dans la paroi de l'étui 1 et la formation mâle par une languette portée par le dos de la partie supérieure du bras.Ainai when the case 1 is placed in a vertical position (Figure 3) the lamp can be fixed there by the introduction of the formation 32 in the groove 10 so as to produce a portable table lamp. In this position, the foot 16 is folded against the lower part 17 of the arm. In a variant, the female formation can be constituted by an opening made in the pa king of the case 1 and the male formation by a tongue carried by the back of the upper part of the arm.

La figure 5 illustre une variante du pied 16 qui comporte des moyens de fixation consitués par une pince formée d'une plaque supérieure 33 solidaire des saillies 20 et d'une plaque inférieure 34 reliée aux saillies 20 par un organe élastiqué tendant à l'appliquer sur la plaque supérieure 33 contre laquelle elle prend appui normalement à l'aide d'une butée 35.FIG. 5 illustrates a variant of the leg 16 which comprises fixing means constituted by a clamp formed by an upper plate 33 integral with the projections 20 and a lower plate 3 4 connected to the projections 20 by an elastic member tending to apply to the upper plate 33 against which it normally bears by means of a stop 35.

L'intérêt d'une telle lampe de lecture portative est qu'elle est très légère et compacte, qu'elle peut être réglée à volonté dans différentes positions par le lecteur et notamment que la distance de l'abat-jour de la surface à éclairer peut être réglée à l'aide du bras télescopique de te:Lle sorte que l'éclairement de cette surface en fonction de sa dimension soit le meilleur possible.The advantage of such a portable reading lamp is that it is very light and compact, that it can be adjusted at will in different positions by the reader and in particular that the distance of the lampshade from the surface to lighting can be adjusted using the telescopic arm of te: Lle so that the lighting of this surface according to its size is the best possible.

De plus cette: lampe peut être alimentée par piles ou secteurs et lorsqu'elle n'est pas utilisée elle peut être rangée de même que l'adaptateur, dans un étui renfermant les piles ou les accumulateurs. Enfin, comme elle peut être fixée sur l'étui qui lui peut être placé verticalement la lampe peut être convertie en lampe de table.In addition this: lamp can be powered by batteries or sectors and when not in use it can be stored like the adapter, in a case containing the batteries or accumulators. Finally, as it can be fixed on the case which can be placed vertically, the lamp can be converted into a table lamp.

Dans une variante le bras peut être réalisé en une seule pièce venue de fabrication avec le pied et l'abat-jour auxquels il est relié par des charnières plastiques.In a variant, the arm can be made in a single piece from manufacturing with the base and the lampshade to which it is connected by plastic hinges.
