Description

Man hat vorgeschlagen, Träger für in frei ausladender Stellung hängende elektrische Leuchten und ähnliche Geräte dadurch zu bilden, daß man Stäbe gegenseitig miteinander verbindet und in der ausladenden Stellung durch eine Art Bajonettverschluß gegeneinander versteift oder aber Stäbe gelenkig und waagerecht winklig zueinanderverschiebbar anordnet. Es sind auch Träger bekannitgeworden mit nach einer Seite hin beweglichen Gliedern, welche durch lange Ansätze sich gegeneinander versteifen. Ferner ist vorgeschlagen worden, Tragelemente durch eine Anzahl gelenkig miteinander verbundene einteilige Glieder zu bilden; derartige Elemente konnten aber entweder nur als senkrechte Tragelemente wirken, oder sie mußten, um ausladend benutzt werden zu können, durch Stifte, Schrauben u. dgl. beim Zusammenstoß je zweier Glieder besonders versteift werden. Alle diese Konstruktionen ermöglichen also nicht, das Tragelement ausladend zu verwenden und ohne weitere Manipulationen nach oben zusammenzurollen, z. B. eine am freien Ende des ausladenden Tragelementes hängende Lampe in einer großen Auswahl verschieden großer Abstände von der Wand oder einem Standfuß sowohl nach oben wie nach unten gerichtet ohne Betätigung besonderer Feststellmittel einzustellen. Diese Möglichkeit ist besonders vorteilhaft zur leichten Erzielung sowohl direkter wie indirekter Beleuchtung über Krankenbetten, Arbeitsplätzen, Maschinen u. dgl.It has been proposed that support for hanging in a freely projecting position electrical To form lights and similar devices by putting rods on each other connects with each other and in the projecting position by a kind of bayonet lock stiffened against each other or rods articulated and horizontally displaceable at an angle to each other arranges. There are also carriers known to be movable to one side Limbs that stiffen against each other through long approaches. It is also proposed been, support elements by a number of hinged one-piece To form limbs; Such elements could either only act as vertical support elements, or they had to To be able to be used expansively, by pins, screws and the like in the event of a collision two links are particularly stiffened. All of these constructions allow so not to use the support element expansively and without further manipulation roll upwards, e.g. B. one at the free end of the projecting support element hanging lamp in a large selection of different distances from the wall or a pedestal both upwards and upwards directed downwards without actuating special locking means. These Possibility is particularly beneficial for easily achieving both more direct and indirect Lighting over hospital beds, workplaces, machines, etc.

Gegenstand der Erfindung ist ein Tragelement für elektrische Leuchten oder ähnliche Geräte, welches aus einer Anzahl gelenkig miteinander verbundener einteiliger, mit ihren Stirnseiten ineinandergreifender, kettenartig aneinandergereihter Glieder besteht, welches dadurch gekennzeichnet ist, daß die vorzugsweise als rechteckige Laschen ausgebildeten Glieder an einer Stirnseite mit einer Nut und an der entgegengesetzten Stirnseite mit einer in die Nut passenden Feder versehen sind und daß je zwei Glieder durch eine Feder und Nut durchsetzende Bohrung durch einen Stift verbunden sind, welcher möglichst nahe an der bei gestrecktem Ausleger obenliegenden langen Seite des rechteckigen Gliedes angeordnet ist.The invention relates to a support element for electrical lights or the like Devices, which are made up of a number of articulated, one-piece, interlocking end faces, consists of links strung together like a chain, which is characterized by that the links, which are preferably designed as rectangular tabs, are located on one end face with a groove and on the opposite end face with one that fits into the groove Spring are provided and that two members are connected by a spring and groove penetrating hole by a pin which is as close as possible to the length at the top when the boom is extended Side of the rectangular member is arranged.

Claims

9 are provided with a groove 15 on their one end face and formed as a tongue 12 fitting into the groove 15 on the opposite end face. Each two members are connected as close as possible to the upper long side when the boom is extended by a spring 12 and groove 15 penetrating pin 11 such that they are rotatable about the pin 1 ι as the axis of rotation. In the projecting position of the support element according to FIG. 1, 2 or 3, the links butt against each other due to the design of their front edges with the surfaces 13. The corners 14 are rounded. As a result of this design of the front ends and the type of their articulated connection, the members 10 stiffen against one another when the carrier is in a projecting position, so that the free end of the same can be loaded, for example by a lamp 24 (FIG. 1).

The stiffening of the carrier is thus without removable and releasable locking means, like screws or pins. As a result, the wearer can with each limb be easily bent back upwards, as shown in Fig. 1 in solid lines and in Fig. 2 is shown in dotted lines. The support arm can also, as FIG. 3 shows, be rolled up and backwards without loosening any locking means. on their underside have in the illustrated embodiment, the link grooves 16, which together form a channel for the insertion of an electrical cord 17. These channels can also be closed by any organs. the Links can also have a cross-section other than rectangular, e.g. B. round, oval, octagonal, etc., but with the parts interlocking at the end faces must be designed so that they are in the projecting position of the support element without further stiffen against each other.

In the embodiment of FIG. 1 is the carrier 10 is hinged at one end around a bolt 18 to a disk 19, which about a vertical axis on a bracket 20, which is located on a base plate 21, is rotatable. In the disc 19 there is an adjusting screw 22, the upper end of which is loose against a lower piece 23 of the support arm. At the outer end of the carrier 10 a lamp 24 is arranged, which in the position shown by dashed lines serves as a work or reading lamp with direct light. At the base plate 21 is a rod 25 is fixed, on which a fork 26 is adjustable in height. Will the Bringing the support arm into the position shown by solid lines, the lamp can be used to generate twilight or indirect light.

In an embodiment according to FIG. 2, the arm io is on a wall board 27 in the Height adjustable and rotatable in the horizontal plane. Here, too, the Lamp 24 from the position shown by solid lines into the position shown by dashed lines Lines shown position are bent, depending on the choice of the bending member the lamp comes to rest more or less far from the wall. This arrangement is particularly suitable over beds, z. B. in hospital rooms, so that the freely hanging lamp in one position with direct light can be used for reading and easily in the other position can be brought for indirect light or twilight. When the lamp 24 is rotatably arranged on the carrier 10 and something to the side of the same, it can be in the position in which in Fig. 2 with dashed lines Lines shown instead of being directed upward, hanging downward, and at different distances from the wall.

Ρλ ϊ Ii N T ANSPRUC H:

Carrier for electric lights or similar devices, which from a number articulated one-piece, with their end faces interlocking, consists of links lined up in a chain-like manner, characterized in that the preferably rectangular Cross-section having members (9) on a narrow end face (15) with a Groove and on the opposite end face (12) with one that fits into the groove Spring are provided and that two links penetrating through a tongue and groove Bore connected to a pin (11) which is as close as possible is arranged on the long side of the rectangular links at the top when the boom is extended.
