Abstract
Abstract A retractable handle assembly for an equipment housing includes a generally U-shaped handle. The side members of the handle are slidably mounted to the housing by means of guide pins which ride in elongated slots on mounting blocks attached to the housing. A communicating slot on the mounting block allows the handle when fully extended to pivot about the guide pins away from an underlying surface so as to be more easily grasped. When retracted the handle is flush with the side panels of the housing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
139 words
A retractable handle assembly for use in conjunction with a housing comprising, in combination: a generally U-shaped handle including a grippable member and a pair of side members attached to respective ends of said grippable member; a pair of handle mounting blocks disposed on said housing adjacent respective ones of said side members, said blocks each including a first slot extending generally parallel to said side members; means including a pair of support pins extending from each of said side members into respective ones of said slots for slidably supporting said handle with respect to said housing; and indexing means including a second slot in each of said mounting blocks intercepting said first slot at a predetermined location for receiving one of said support pins when said handle is fully extended to enable said handle to be pivoted upwardly.
Claim 2
Dependent Claim
139 words
A retractable handle assembly for use in conjunction with a housing comprising, in combination: a generally U-shaped handle including a grippable member and a pair of side members attached to respective ends of said grippable member; a pair of handle mounting blocks disposed on said housing adjacent respective ones of said side members, said blocks each including a first slot extending generally parallel to said side members; means including a pair of support pins extending from each of said side members into respective ones of said slots for slidably supporting said handle with respect to said housing; and indexing means including a second slot in each of said mounting blocks intercepting said first slot at a predetermined location for receiving one of said support pins when said handle is fully extended to enable said handle to be pivoted upwardly.
Claim 3
Dependent Claim
52 words
A retractable handle assembly as defined in claim 1 wherein said support pins are aligned front and rear with respect to said first slots, and wherein said second slots intercept said first slots such that the rear-most of said support pins are received therein as said handle reaches said fully extended position.
Claim 4
Dependent Claim
33 words
A retractable handle assembly as defined in claim 2 wherein said side members each include a notch dimensioned to clear the side panels of said housing when said handle assembly is fully extended.
Claim 5
Independent Claim
132 words
An apparatus housing comprising, in combination: a generally U-shaped handle including a grippable member and a pair of side members attached to respective ends of said grippable member; top, bottom and side panel members attached to respective ends of said grippable member; a pair of handle mounting blocks attached to one of said housing panel members adjacent respective ones of said side members, said blocks each including a first slot extending generally parallel to said side members; means including a pair of support pins extending from each of said side members into respective ones of said slots for slidably supporting said handle; and indexing means including a second slot communicating with said first slot for enabling said handle to pivot upwardly away from said side panels when in a fully extended position.
Claim 6
Independent Claim
132 words
An apparatus housing comprising, in combination: a generally U-shaped handle including a grippable member and a pair of side members attached to respective ends of said grippable member; top, bottom and side panel members attached to respective ends of said grippable member; a pair of handle mounting blocks attached to one of said housing panel members adjacent respective ones of said side members, said blocks each including a first slot extending generally parallel to said side members; means including a pair of support pins extending from each of said side members into respective ones of said slots for slidably supporting said handle; and indexing means including a second slot communicating with said first slot for enabling said handle to pivot upwardly away from said side panels when in a fully extended position.
Claim 7
Dependent Claim
51 words
An apparatus housing as defined in claim 4 wherein said support pins are aligned front and rear with respect to said first slots, and wherein said second slots intercept said first slots such that the rear-most of said support pins are received therein as said handle reaches said fully extended position.
Claim 8
Dependent Claim
32 words
An apparatus housing as defined in claim 5 wherein said side members each include a notch dimensioned to clear the side panels of said housing when said handle assembly is fully extended.
Claim 9
Dependent Claim
