Abstract
An hot shoe attachment for fitting a flash gun or the like to the hot shoe of a camera has a flanged body for fitting to the hot shoe with a locking ring screw threaded thereto for clamping it in place. Electrical contact means on the body on the attachment are resiliently urged towards and against the hot shoe when the attachment is fitted. As the locking ring is unscrewed to release the attachment, the contact means are simultaneously withdrawn from the hot shoe to avoid damage by contact therewith as the flash gun or the like is removed. Only when the locking ring is again screwed to its clamping position do the contact means again project from the body. The contact means are normally mounted in a bushing which itself has flanges engaged by the locking ring at least as the locking ring is unscrewed. Resilient urging means may be applied to the contact means, the bushing or both.
