Abstract
Abstract 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.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
164 words
A carrying handle arrangement for a projector housing or the like comprising: a first housing portion including a pair of spaced bearing receivers each defining a receiver socket; a carrying handle including an elongated base portion and two extending legs, each of said legs including an elongated bearing pin arranged to fit with said receiver sockets; a second housing portion for mating engagement with said first housing portion to retain said handle within said receiver sockets; and means for resiliently retaining said bearing pins within said receiver sockets in a frictional fit relationship and permitting rotation of said carrying handle about an axis through said bearing pins, said resilient retention means comprising an elongated slotted portion formed in each of said bearing receivers and interconnecting with each of said respective bearing receiver sockets to provide said bearing receiver sockets with a resilient characteristic and the diameter of said bearing pins being a predetermined dimension larger than the interfitting dimension of said bearing receiver sockets.
Claim 2
Dependent Claim

A carrying handle arrangement for a projector housing or the like comprising: a first housing portion including a pair of spaced bearing receivers each defining a receiver socket; a carrying handle including an elongated base portion and two extending legs, each of said legs including an elongated bearing pin arranged to fit with said receiver sockets; a second housing portion for mating engagement with said first housing portion to retain said handle within said receiver sockets; and means for resiliently retaining said bearing pins within said receiver sockets in a frictional fit relationship and permitting rotation of said carrying handle about an axis through said bearing pins, said resilient retention means comprising an elongated slotted portion formed in each of said bearing receivers and interconnecting with each of said respective bearing receiver sockets to provide said bearing receiver sockets with a resilient characteristic and the diameter of said bearing pins being a predetermined dimension larger than the interfitting dimension of said bearing receiver sockets.
Claim 3
Dependent Claim
39 words
The carrying handle arrangement of claim 1 wherein said second housing portion further comprises means for mating with said bearing receivers and said bearing pins to aid in the retention of said bearing pins within said bearing receiver sockets.
Claim 4
Dependent Claim
32 words
The carrying handle arrangement of claim 2 wherein said carrying handle is rotatable from a first generally upright position for carrying and a second recessed storage position into said second housing portion.
Claim 5
Dependent Claim
40 words
The carrying handle arrangement of claim 3 wherein said handle legs include a first portion at right angles to said base portion generally forming a U and a second arcuate portion extending between said first portion and said bearing pins.
Claim 6
Dependent Claim
50 words
