Flash unit

The "price increase" concerns a flash unit for cameras with a rotating part that has several reflectors with flash lamps with melting tips arranged parallel to the axis of rotation contains, which can be brought into flashing position one after the other, in which the base contacts are against fixed ignition contacts of the camera, with the rotating part being transparent Schutsfenster on all sides feet closed cube is formed and behind the reflector scratch windows lying flash lamps with their melting tip in an upper one Recess and is received with its pinch foot in a lower opening of the reflector, according to patent Hr. 1,447,878.

In the case of the patented Hr. 1447 S78 proposed cube-shaped Flash device is provided in the base of a hole, in one of the balls attached to the camera as a holder h ± eiiiregt.

In the proposal according to patent Mr. 1 447 878 has it sicii as Disadvantage turned out to be that in order to achieve a firm j a good contact To reach the flash cube with the camera making sure the flash cube sits which fixed on the camera The wave must be relatively strong and protrude sufficiently through the hole into the inside of the Y / cube. This requires a relatively large space requirement, at the expense of the external dimensions of the entire flash cube goes and one prevents further compaction of the cube. Furthermore, the

relatively large hole in the base plate dust can penetrate the inside of the cube, resulting in a longer storage time of the Opposite devices and also during use due to pollution of the reflectors to the impairment of the Light seizure leads.

The task of the innovation is therefore generally to address these disadvantages I to eliminate and a flash unit according to patent no. 1 447 878ί

to create, in which the cube I

shaped housing tightly closed at the bottom and a |

simple, secure fit of the device on the camera §

sure tory setting up the device warranty on the Kameia \

is performing. ^f

In the case of the flash device, this task is described in the opening paragraph mentioned type solved in that a plate-shaped device base is provided, the einp in the middle downwards pointing pin and around the pin at a distance from one another, pointing in the radial direction locking has noses. I.

In the event that the flash bulbs are inside the flash cube are triggered electrically via camera contacts in an advantageous development of the JTeuermig " having flashlight device power supply wires of the flashlights to form base contacts through the device base passed through and extending in the radial direction from the pin, from the device base downwards projecting surfaces attached in a known manner.

As a result, good contact is made between the adjustment mechanism and the flash position Flash lamp secured with the ignition contact of the camera.

From British Patent No. · 952 318 it is on known, the power supply wires of in sheaths of a strip-shaped tape made of transparent synthetic Plastic arranged flash lamps to form strip-like thickenings at the bottom of the tape To attach contacts.

An exemplary embodiment of the flash device containing the innovation is described below with reference to the drawings explained.

The exemplary embodiment shown in the drawings of a replaceable flash light device 14 in accordance with the new air can be placed on a camera 10, which has electrical ignition contacts 27, 28 and a sintering mechanism 25, which allows the device 14 to be rotated one after the other in such a way that the 3 © d «flash lamp 15 is in electrical connection with the Ignition contacts 27 »28 of the camera is brought.

The device 14 contains several flash lamps 15 * each of which cooperates with a reflector 17. Each lamp 15 forms a unit with the associated reflector 17, which longitudinal the inner surface of a transparent wall of a housing 18 is applied.

The housing 18 is tightly connected to the base 16 of the device 14 -which has an external plate of the center of which protrudes downward from a pin 23. Around the pin 23, several locking lugs 24, which are spaced apart in the radial direction, are attached and stand up at the camera attached to the flash unit in engagement with the Adjustment mechanism 25 of the camera 10.

The power supply wires run through the base 16 19> 20 as base contacts for the flash lamp 15. These are shaped into brackets which protrude downwards Surfaces 21 on the base 16, which from the pin 23 in emanate in the radial direction, are arranged and fixed.

A device 14 is inserted into the mechanism 15 to take the camera flash unit assembly into use. Of the Film is exposed by depressing the button 13, with one also powered by a battery Circuit to the power supply wires 19 »20 is closed by the ignition contacts 27, 28 of the camera. The adjustment mechanism 25 contains a spring 26, which the device 1 ″ by means of acting on the locking lugs 24 Locking force holds. The adjustment mechanism 25 can for example be operated by the film transport lever (not tilted) on the camera 10 to turn the device 14 by 90 to rotate so that a new flash lamp 15 with the contacts 27,28 is brought into engagement. When all lamps. 15th have been ignited, the device 14 is removed from the Kaiaera 10 and thrown away. The surface 29, 30 of the retaining lugs 24 facilitate the insertion and removal of the device I ^ across the spring 26.

Claims (2)

Protection claims 1. Flashlight device for cameras with a rotating part that contains several reflectors with flash lamps with melting tips arranged parallel to the axis of rotation, which can be brought into the flash position one after the other, in which the base contacts of the flash lamps lie against fixed ignition contacts of the camera, whereby the rotating part is designed as a central transparent protective window that is firmly closed on all sides and the flash lamps located behind the reflector protective windows are accommodated with their melting tip in an upper recess and with their pinch foot in a lower opening of the reflector, according to patent no. 1 khj 878, characterized in, that a plate-shaped device sock (16) is provided which has a pin (23) pointing downwards in its ^ itte and around the pin (23) at a distance from one another, pointing in the radial direction locking lugs (2A). 2. Flash device according to claim 1, characterized in that power supply wires (19, 20) of the flash lamps (15) to form the base contacts through the device base (16) passed through and extending in the radial direction from the pin (23) from the device base (16) downwardly projecting surfaces (21) are attached in a manner known per se.
