Abstract

A rotatable grip for cameras consists, according to the invention, of a play-free latching mechanism comprising, arranged one after the other, a bearing ring (2), a grip plate (3), a leaf spring (4) and steel balls (5) deposited therein with a form fit. According to the invention, leaf spring (4) and bearing ring (2) are connected to the base body of the camera by the balls being pushed into the holes (8) of the grip plate (3) by the leaf spring (4). The connection is preferably effected with the aid of a screw-connection (6). Due to the rotation of the grip (1), the balls (5) are pushed out of the hole of the grip plate (3) counter to the spring force. The grip (1) is pivoted until the balls (5) latch in the desired position into the holes of the selected latch position. In order to secure the selected latch position in the long term, a blocking plate (7) which can pivot about the axis of rotation of the grip plate (3) can prevent the latch balls (5) from moving.

Description

technical field [0001] The invention relates to a rotatable handle for cameras, in particular for reflex cameras. The grip according to the invention is connected to the base body of the camera by means of a locking mechanism. Background technique [0002] Cameras equipped with rotatable handles are known, with the rotatable handles having a wide variety of configurations. In US Patent No. 4,405,223 a reflex camera with a pistol grip is described, wherein the grip is secured by means of a cage structure. In this case, the pivoting ability is greatly restricted and leads to loosening of the retaining element during use. From DE19534231 is known a pivoting holding handle structure in a reflex camera. However, a drawback in this construction is that the play of the locking means is too great, thus having a negative effect on the operability. Contents of the invention [0003] It is an object of the present invention to provide a camera with a housing and a rotatable handl...
