DE1950201A1 - Flash lamp unit for several flash lamps that can be mechanically ignited - Google Patents

Description

State of the art

The invention relates to flash photography and more particularly disposable multiple lamp kit units for use Kit of a camera or other photographic apparatus} which is designed so that it can carry and ignite such a unit during operation.

Ee a uniform pack is already known, the several Includes photoflash bulbs and associated individual reflectors (U.S. Patent 3 244 087) ο In use, the lamps in such a pack are sequentially arranged with reference to the image = Axis of a camera aligned and electrically synchronized ignited with the actuation of the camera shutter.

Photoflash laraps have been proposed for ignition do not require any electrical voltage. In such lamps, an ignition charge is placed in a metal tube that extends from the bottom of the lamp stands off ”is ignited by a blow and in turn ignites one Fuel and a combustion-promoting gas in the lamp bulb «

Such a mechanically ignitable flashlight offers an important advantage because an electrical ignition source is no longer required, but various problems have arisen ₉ when such a completely flashlight is to be used reliably with cameras

First of all, it was found that the stiffness of the detonator * pipes during the site is a key factor affecting the Ignition reliability influenced by mechanically ignitable flash lamps. So there is the problem of using a Kontageeinric?: Do £ for such flash lamps in cameras, in which the igniter tubes eteif opposite the apparatus for

mechanical ignition are supported. This Profclea will supplemented by the additional consideration that a flashlight or a flashlight pen unit, zveek appropriately easier-i to attach and remove and it should be is that the support is movable with respect to the camera to record several lamps To index unit "

A second problem with regard to mechanically detonable flash units is that the base plate of the unit should be rigidly supported, as just discussed, but similar

should be accessible for the igniter tubes of the unit, so that they can receive an ignition strike from an ignition mechanism »The problem is made worse by considering that a base plate and an associated socket or receptacle provide the largest possible access zone are intended to allow mechanical ignition by various different striking mechanisms that “Alarm clocks used in various cameras in which the flash lamp unit is used ο

Devices and working catfish for the ignition of lightning powder have been developed for a very long time but they do not provide an acceptable solution to the problems mentioned above. Also the lamp units mentioned at the beginning with electric ignition do not contain any teaching which could overcome the above difficulties due to the requirement for a stiff support and a large impact zone for a mechanically ignited lamp result.

Summary of the invention

The invention addresses the problems just discussed and provides a device with which a Through it was an ignitable flash unit with several lines can be detachably mounted on a camera in such a way that the igniter tubes of the unit are rigid with respect to the device are held, but are arranged in such a way that they present a large "impact area" to the impact ignition

The object of the invention is therefore to make available a base plate that is suitable, together with a Recording or socket in a camera to be used to create a mechanically ignitable teaching lamp flash unit so that it can be ignited and rotated in a camera for alignment.

Furthermore, a flash unit with a base plate for supporting the unit is to be made available by the invention, with which the unit can be rigidly supported with respect to a camera, but easily attached and can be removed.

Welter is said to be a flash unit with a Base plate are made available with which a mechanically ignitable flash lamp can be rigidly supported and which allows a large β access field for the ignition failure,

In addition, the invention should be a mechanically βundbaren Mebrlamp flash unit with a cheaper, and easy to manufacture Base plate for supporting the unit in a camera could be made available.
