Abstract

A single bodied unitary flash attachment containing a flash lamp and a power supply is attached to and supported upon the top of a camera by support elements including a bayonet-type electrical contact member and a U-shaped support. Electrical contact is provided between the flash attachment and the camera by inserting the bayonet-type electrical contact within a flash bar receptacle on the top of the camera. The U-shaped support member clampingly engages the camera view finder to provide stability and support during camera photoflash operation.

Claims

1. An improved photoflash attachment for use with a camera of the type having a flash bar receptacle and a view finder positioned at the top of said camera and offset from the center thereof, said view finder being substantially rectangular in at least a portion thereof and having a predetermined height and a predetermined width in said rectangular portion, said attachment comprising in combination:

a flash lamp and a power pack mounted in a unitary housing,

support means for supporting said housing on said camera,

said support means including a U-shaped support member having a base portion and a pair of resilient support arms extending from said base portion, said pair of support arms being spaced from each other a distance substantially equal to said predetermined width of said view finder,

said base portion connected to the bottom of said housing so that said support arms extend downwardly from the bottom of said housing and offset from the center of said housing to clamp onto said view finder to support said housing, and

an electrical contact member protruding from the bottom of said housing and positioned to be inserted into said flash bar receptacle on said camera when said photoflash unit is mounted on the top of said camera.

2. The photoflash attachment of claim 1 wherein said electrical member is located within a recess formed in the bottom of said flash attachment for receiving a corresponding raised portion on the top of said camera containing said flash bar receptacle.

3. The photoflash attachment of claim 2 that further includes a projection on the inner side of each of said support arms and spaced from said base portion a distance substantially equal to the height of said view finder so that said projections clampingly envelope said view finder to provide support for said attachment.
