A carrying handle arrangement for a projector housing or the like is provided wherein the handle frictionally fits with and is retained between first and second housing portions. The carrying handle is rotatable between a first upright carrying position and a second storage position wherein the handle fits within a recess defined within one of the housing portions to form a flat surface with the housing portion. The carrying handle is retained by the frictional fitting of integral bearing pins with respective bearing receivers defined in one of the housing portions. The handle and bearing receiver structures include a resilient retention arrangement defined by the frictional fit of the bearing receivers and bearing pins. The resilient retention arrangement provides a frictional fit relationship between the handle and the housing. Thus, the handle remains fixed in position for easy grasping in the upright carrying position while restricting movement and preventing rattling of the handle in the recessed storage position. The resilient retention arrangement can be achieved by fabricating the handle bearing pins with a diameter of a predetermined larger dimension than the dimensions of the bearing receivers. The bearing receivers in one arrangement each include a narrow, elongated slot communicating with the portion of the bearing receiver frictionally fitting the bearing pin. In another arrangement, a diametric slot is defined along a substantial axial length of the bearing pins.

Rotatable carrying handle arrangement

A motion picture projector is provided with a manually shiftable mode controller assembly for selecting various operational modes and apparatus for the automatic threading and rewinding of film. The operative mechanical components of the projector are mounted on a unitarily molded housing including molded structures and portions that independently and cooperatively with other control assemblies and interfitting structures provide features and improved operational characteristics. The molded housing interfits with a take-up reel cover, a control assembly cover and a rear cover that rotatably engages a carrying handle. Structure to define a film path, an automatic threading assist structure, a film speed detent structure and a position defining structure for the mode controller assembly are also provided by and integrally molded with the housing.
