Description

The Invention relates to a diving lamp according to the preamble of the claim, as it is well known and in use. These lamps have the disadvantage that you turn up, dismantle the lamp and the Reflectors must change, if you change the beam (bundle up or scatter) wants.

The Diving is very difficult, especially since the lamps are not flooded are.

task The invention is to design the dive light so that under water the beam changes can be.

In the following embodiments of the invention with reference to drawings - 1 to 3 - described. These embodiments realize the basic idea of the invention to be able to adjust the relative position of the luminous element (lamp) to the reflector by means of an adjusting device, so that the desired radiation behavior is obtained without the diver's lamp being opened and / or the reflector and / or lamp holder being dismantled, or replace it with another type.

For all embodiments:
The housing of the dive light is cylindrical, designed especially circular cylindrical. It is through the glass 2 and the removable caseback 3 sealed watertight. Behind the glass 2 sits a hollow mirror-shaped reflector 4 which is made of a reflective sheet metal. On its centric mirror axis 15 owns the reflector 4 a breakthrough / hole 16 , In this breakthrough sits the lamp 5 in lamp socket 6 on a lamp holder 7 , The position of the lamp 5 is chosen so that the lamp is in or near the focal point of the reflector. By the selected relative position of the lamp to the reflector of the beam is determined: is the lamp in focus, creates a non-scattering beam; if the lamp - from the reflector - is in front of the focal point, a focused beam is produced; If the lamp is located behind the focal point - from the reflector - a scattering beam is created. This is to come back later.

The housing 1 is also filled by batteries or accumulators to power the lamp. These batteries or accumulators are - combined in a pack - between housing bottom 3 and the battery holder 10 accommodated. You can by removing the case bottom 3 out of the case 1 be taken out.

This is the case back 3 by bottom thread 17 detachably screwed in the housing. The caseback 3 has a centric approach 18 with an external thread, whose axis coincides with the axis of the housing and the mirror axis 15 flees. On this thread is the spacer tube 12 screwed. The spacer tube 12 has at its other end an external thread, on which with a central internal thread, the circular disc-shaped battery plate 10 screwed. Between battery retaining plate and housing bottom 3 The battery pack is replaceably attached when the case bottom out of the case 1 is unscrewed.

• • dass die Lampenhalterung 7 fest und die Halterung des Reflektors axial verschieblich, jedoch drehgesichert im Gehäuse 1 angebracht wird,
• • oder dass beide, die Lampenhalterung 7 und die Halterung des Reflektors axial verschieblich, jedoch drehgesichert im Gehäuse 1 angebracht werden und beide auf einer gemeinsamen drehbaren Gewindespindel mit jeweils gegensinnigen Gewinden sitzen.

Facing away from the battery pack, the battery retaining plate has guide pins 8th parallel to the mirror axis 15 are aligned. On these guide pins 8th is the lamp holder 7 slidably guided in the direction of the mirror axis, so that the guide pins 8th form a protection against twisting. Due to the axial displacement of the lamp holder 7 becomes the relative distance between lamp 5 and reflector 4 adjusted to the desired setting of the beam formation of the dive light. It can be seen that the relative distance can also be adjusted by

• • that the lamp holder 7 fixed and the holder of the reflector axially displaceable, but secured against rotation in the housing 1 is attached
• • or that both, the lamp holder 7 and the holder of the reflector axially displaceable, but secured against rotation in the housing 1 are attached and both sit on a common rotatable threaded spindle with opposing threads.

Essential for the realization of the invention is in all embodiments that the relative movement between the lamp 5 and reflector 4 by a spindle / control rod / threaded spindle 11 can be adjusted from the outside, with lamp holder 7 or reflector at one end of the spindle 11 are attached and the spindle with the other end of the housing bottom 3 penetrates and a thumbwheel 19 has.

• • In dem Ausführungsbeispiel nach 1 ist die Spindel 11 mit der Lampenhalterung 7 durch eine Befestigungsmutter 9 fest verbunden und daher gemeinsam mit der Lampenhalterung 7 drehgesichert jedoch axial beweglich. Am anderen Ende kämmt die Spindel über eine Gewindepaarung mit einer Stellmutter 13, welche in dem Loch des Ansatzes 18 drehbar geführt und einerseits durch den außen am Gehäuseboden 3 anliegenden Stellknopf 19, andererseits durch die an der freien Stirnfläche des Ansatzes 18 anliegende, auf die Stellmutter 13 aufgeschraubte Gegenmutter 14 axial festgelegt ist. Durch Drehen des Stellknopfes wird Spindel 11 mit der Lampenhalterung 7 axial verschoben und dadurch der Relativabstand zwischen Lampe 5 und Reflektor 4 zur gewünschten Einstellung der Strahlbildung der Taucherlampe verstellt. Dieses Ausführungsbeispiel der Erfindung erlaubt auch die nachträgliche Umrüstung handelsüblicher Taucherlampen.
• • In dem Ausführungsbeispiel nach 2 ist die Spindel 11 mit der Lampenhalterung 7 durch Sicherungsring 9 drehbar, jedoch gegen relative Axialbewegung gesichert verbunden. Am anderen Ende kämmt die Spindel über eine Gewindepaarung mit dem Ansatz 18. Durch Drehen des Stellknopfes 13 wird Spindel 11 gedreht und mit der Lampenhalterung 7 axial verschoben und dadurch der Relativabstand zwischen Lampe 5 und Reflektor 4 zur gewünschten Einstellung der Strahlbildung der Taucherlampe verstellt.
• • In dem Ausführungsbeispiel nach 3 ist die Spindel 11 mit der Lampenhalterung 7 durch eine Gewindepaarung verbunden. Die Spindel 11 ist außerhalb des Gehäuses mit dem Stellknopf 19 fest verbunden und in dem Loch des Ansatzes 18 drehbar geführt, jedoch einerseits durch den am Gehäuseboden 3 anliegenden Stellknopf 19 und andererseits durch den an der freien Stirnfläche des Ansatzes 18 anliegenden Stützring 14 axial festgelegt. Durch Drehen des Stellknopfes 19 und der Spindel 11 wird die Lampenhalterung 7 axial verschoben und dadurch der Relativabstand zwischen Lampe 5 und Reflektor 4 zur gewünschten Einstellung der Strahlbildung der Taucherlampe verstellt.

For this purpose, in all embodiments of the centric approach 18 of the case bottom 3 and the spacer tube 12 perforated throughout. In this hole 16 is the spindle / control rod / threaded spindle 11 guided.

• • In the embodiment according to 1 is the spindle 11 with the lamp holder 7 through a fastening nut 9 firmly connected and therefore together with the lamp holder 7 non-rotating but axially movable. At the other end, the spindle meshes with an adjusting nut via a thread pairing 13 which is in the hole of the neck 18 rotatably guided and on the one hand by the outside of the housing bottom 3 adjoining knob 19 , on the other hand by the at the free end face of the approach 18 fitting, on the adjusting nut 13 screwed locknut 14 is fixed axially. Turning the adjusting knob turns the spindle 11 with the lamp holder 7 axially displaced and thereby the relative distance between the lamp 5 and reflector 4 adjusted to the desired setting of the beam formation of the dive light. This embodiment of the invention also allows the subsequent conversion of commercially available dive lights.
• • In the embodiment according to 2 is the spindle 11 with the lamp holder 7 by circlip 9 rotatable, but secured against relative axial movement connected. At the other end, the spindle meshes with the neck via a thread pairing 18 , Turn the adjusting knob 13 becomes spindle 11 turned and with the lamp holder 7 axially displaced and thereby the relative distance between the lamp 5 and reflector 4 adjusted to the desired setting of the beam formation of the dive light.
• • In the embodiment according to 3 is the spindle 11 with the lamp holder 7 connected by a thread pairing. The spindle 11 is outside the housing with the knob 19 firmly connected and in the hole of the neck 18 rotatably guided, but on the one hand by the at the bottom of the case 3 adjoining knob 19 and on the other hand by the at the free end face of the approach 18 adjacent support ring 14 fixed axially. Turn the adjusting knob 19 and the spindle 11 becomes the lamp holder 7 axially displaced and thereby the relative distance between the lamp 5 and reflector 4 adjusted to the desired setting of the beam formation of the dive light.

Further Alternatives in the form of kinematic reversals are conceivable, however less easy to realize.
