KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft eine Handhabe für elektrische Lampen oder sonstige Vorrichtungen, besonders zum Gebrauch für Aerzte, Chirurgen, Zahnärzte u. s. w., um für gewöhnlich nicht zugängliche Stellen des menschlichen Körpers nach Wunsch erreichen zu können. Die neue Handhabe dient nicht allein zum Führen und Bewegen der an ihr angebrachten Lampe oder dergl., sondern sie ist gleichzeitig als Contactvorrichtung eingerichtet, und zwar derart, dafs man mittelst derselben sowohl ununterbrochenen als auch unterbrochenen Stromschlufs in einfachster, bequemster Weise bewirken kann.The invention relates to a handle for electric lamps or other devices, Especially for use by doctors, surgeons, dentists and so on, around areas of the human body that are usually inaccessible to be able to reach as desired. The new handle is not only used to guide and Moving the lamp or the like attached to it, but it is also a contact device arranged in such a way that by means of them one can find both uninterrupted as well as interrupted power supply in the simplest, most convenient way.

Der Gegenstand der Erfindung kann auch zu verschiedenen anderen Zwecken, aufser zur Beleuchtung bei ärztlichen Verrichtungen u. s. w., Verwendung finden. So z. B. lassen sich auch elektrisch zu bethätigende (chirurgische) Instrumente u. s. w. an denselben anschliefsen.The subject matter of the invention can also be used for various other purposes besides Lighting can be used for medical services and so on. So z. B. can also Connect electrically operated (surgical) instruments and so on to the same.

Auf der Zeichnung sind zwei Ausführungsformen der Einrichtung dargestellt, und zwar zeigtIn the drawing, two embodiments of the device are shown, namely shows

Fig. ι einen Längsschnitt durch die eine Ausführungsform der aus einander nehmbaren Handhabe,Fig. Ι a longitudinal section through one embodiment of the removable from each other Handle,

Fig. 2 einen Längsschnitt durch die andere Ausführungsform einer solchen Handhabe.2 shows a longitudinal section through the other embodiment of such a handle.

Die beiden Haupttheile der Handhabe sind leicht von einander zu trennen, wieder zusammenzustecken und gegen einander einzustellen. Aufser Gebrauch sollen die beiden Theile ganz aus einander gezogen sein.The two main parts of the handle are easy to separate from one another and to put together again and adjust against each other. When used, the two parts are said to be completely drawn apart.

Der eine Theil besteht aus der Hülse 17 aus leitendem Material, in welcher ein Rohr 18 aus Isolirmaterial steckt, welches wiederum eine Röhre 19 aus leitendem Material enthält. Hülse 17 kann beliebige Länge haben; Rohr 18 und 19 haben gleiche Länge und ragen bei 20 und 21 aus der Hülse 17 hervor, während letztere auf der gegenüberliegenden Seite bei, 22 vorragen kann. Draht 15 ist an das Rohr 19 und Draht 12 an die Hülse 17 oder umgekehrt angeschlossen. Eine an der Hülse 17 befestigte Stromschlufsfeder 23 bekannter Art ragt über das innere Ende der ersteren hinaus. Der andere Theil der Handhabe besteht aus einer Hülse 24 von gleichem Durchmesser, wie Hülse 17. Dieselbe enthält ein nichtleitendes Rohr 25, über dessen Enden Hülse 24 bei 26 und 27 hinausragt und welches einen ebenfalls über ihre beiden Enden bei 29 und 30 hinausragenden Contactstab 28 enthält. Die Enden 27 und 30 sind zweckmäfsig ebenso lang oder ein wenig länger, wie das Ende 20 des Rohres 18. Um beide Theile mit einander zu verbinden, wird Rohr 18 in das Hülsenende 27 geschoben, wobei gleichzeitig das Stabende 30 in das Rohr 19 eintritt, so dafs zwischen Draht 15 durch Rohr 19 und Stab 28 mit einem sich gegen das andere Ende dieses Stabes legenden Contact elektrische Verbindung hergestellt ist. Es besteht, dagegen zwischen den beiden Hülsen 24 und 17 keine elektrische Verbindung, bis das Rohr 18 so weit einge-One part consists of the sleeve 17 made of conductive material, in which a tube 18 made of insulating material is inserted, which in turn includes a tube 19 of conductive material. Sleeve 17 can be of any length; Tube 18 and 19 have the same length and protrude at 20 and 21 from the sleeve 17, while the latter on the opposite side at, 22 can protrude. Wire 15 is attached to tube 19 and wire 12 to sleeve 17 or vice versa connected. An electric circuit spring 23 of known type attached to the sleeve 17 protrudes beyond it the inner end of the former beyond. The other part of the handle consists of one Sleeve 24 of the same diameter as sleeve 17. It contains a non-conductive one Tube 25, beyond the ends of which sleeve 24 protrudes at 26 and 27 and which is also one Contains contact rod 28 projecting beyond its two ends at 29 and 30. The ends 27 and 30 are expedient as well long or a little longer, like the end 20 of the tube 18. Around both parts with each other To connect, tube 18 is pushed into the sleeve end 27, at the same time the Rod end 30 enters tube 19 so that between wire 15 through tube 19 and rod 28 electrical connection with a contact placed against the other end of this rod is made. There is, however, no electrical between the two sleeves 24 and 17 Connection until the pipe 18 is so far

Claims

is pushed so that both sleeves touch each other. At the other end of the sleeve 24 and rod 28 sits an electric lamp or other device, of which one pole in a suitable Way with rod 18 and the other with the sleeve 24 is connected. Do they touch Sleeves 24 and 17, the circuit is completely closed. When sleeve 24 die Sleeve 17 is not touched, but is still on the tube 18, is the circuit interrupted. If you press the end of the spring 23 down, the circuit is also closed. So you can use the handle both uninterrupted and after Establish interrupted power supply if desired. If desired you can by application Suitable material and appropriate arrangement also make the handle flexible.

When the device is in use, the sleeve 24 with the parts attached to it is withdrawn from tube 18.

Fig. 2 shows another embodiment of the handle. This consists of two Sleeves 17 and 24 with tubes 18 and 25 of the same design as in FIG. 1. Here, however the wire 15 passed directly through tube 18 and 25 and with the one Pole of the lamp or other device connected. If you take this handle off each other, the sleeve 17 remains on the wire 15; so no part becomes wholly loose.

Sponsorship τ claims:

ι. Handle for lamps or other medical use for lighting and Devices used to treat hard-to-reach places, marked by two mutually merging parts that can be separated when needed, one of which is a non-conductive tube (18) with conductive outer sleeve (17) and conductive inner sleeve (19), while the other Part (carrying the lamp or the like) consists of a non-conductive tube (25) with a conductive There is outer sleeve and central contact rod (28), the latter of which is attached to one Pole of the lamp are connected, the conductive parts being of such length that when the two handle parts are pushed into one another, the contact rod (28) and the inner sleeve (ig) always connect, while both by pushing together the outer sleeves (17 and 24) more constant, as well as those that do not touch each other Outer sleeves by pressing down a spring on one of the sleeves for intermittent electricity can be produced.

2. Device according to claim 1, characterized in that that with the omission of the contact rod and the conductive inner sleeve of the a lead wire (15) is passed directly through both non-conductive cores (18 and 25).
