Abstract
Abstract A skid plate retained below an electronic register module includes a plurality of cantilevered spring fingers formed by parallel pairs of slots in the skid plate. Each cantilevered spring finger includes a frusto-conical button which bears against a back plate in a housing during installation of the electronic register module therein. A rear end of the back plate includes a pair of mouse holes into which a rear pair of frusto-conical buttons engage during an intermediate stage of inserting the electronic register module into the housing. This engagement establishes the correct side-to-side positioning of the rear end of the electronic register module. A front cantilevered spring finger and its associated frusto-conical button resiliently urge the front of the electronic register module upward during substantially all stages of installation and in the operational position thereof. When the electronic register module is advanced further into the housing, the rear pair of frusto-conical buttons ride up onto the surface of the back plate thereby providing an upward resilient force for securing the electronic register module into its operational position. At least one depression is provided in the back plate for receiving a frusto-conical button at the operational position of the electronic register module.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
149 words
An electronic register and meter frame for an electric meter comprising: an electronic register module; said meter frame including at least a face plate and a back plate; means for affixing said back plate spaced a predetermined distance from said face plate, thereby providing a predetermined space therebetween; said electronic register module including a skid plate affixed thereto; said skid plate including at least a first cantilevered spring finger thereon; a first button in said first cantilevered spring finger; said first button contacting and sliding upon said back plate during insertion and removal of said electronic register module, and said first cantilevered spring finger providing a first resilient force urging said electronic register module toward said face plate; and guidance means at a rear surface of said back plate for providing side-to-side guidance of said at least a first button during an intermediate stage of said insertion and removal.
Claim 2
Dependent Claim
149 words
An electronic register and meter frame for an electric meter comprising: an electronic register module; said meter frame including at least a face plate and a back plate; means for affixing said back plate spaced a predetermined distance from said face plate, thereby providing a predetermined space therebetween; said electronic register module including a skid plate affixed thereto; said skid plate including at least a first cantilevered spring finger thereon; a first button in said first cantilevered spring finger; said first button contacting and sliding upon said back plate during insertion and removal of said electronic register module, and said first cantilevered spring finger providing a first resilient force urging said electronic register module toward said face plate; and guidance means at a rear surface of said back plate for providing side-to-side guidance of said at least a first button during an intermediate stage of said insertion and removal.
Claim 3
Dependent Claim
125 words
An electronic register and meter frame according to claim 1 wherein: said at least a first cantilevered spring finger includes at least first and second cantilevered spring fingers; said second cantilevered spring finger includes a second button; said first button being disposed at a front end of said skid plate, and said first cantilevered spring finger providing said first resilient force urging a front end of said electronic register module toward said face plate; and said second button including means for sliding contact with a surface of said back plate, and said second cantilevered spring finger providing a second resilient force urging a rear end of said electronic register module toward said face plate, whereby said electronic register module is secured in said operational position.
Claim 4
Dependent Claim
44 words
An electronic register and meter frame according to claim 2 wherein said guidance means include a mousehole in said back plate, said second button is slideable into said mousehole at said intermediate stage, and edges of said mousehole being effective for providing said guidance.
Claim 5
Dependent Claim
19 words
An electronic register and meter frame according to claim 2 wherein said first and second buttons are frusto-conical buttons.
Claim 6
Dependent Claim
70 words
An electronic register and meter frame according to claim 4 wherein said back plate includes at least one depression disposed in a position which aligns with one of said first and second frusto-conical buttons when said electronic register module is in its operational position, a tip of said frusto-conical button being positioned to enter said depression and further being effective for retaining said electronic register module in said operational position.
Claim 7
Dependent Claim
27 words
An electronic register and meter frame according to claim 2 wherein said skid plate includes a first access slot for access to components behind said skid plate.
Claim 8
Dependent Claim
67 words
An electronic register and meter frame according to claim 2 wherein said face plate includes at least one slot and said electronic register module includes at least one locking ramp, said at least one locking ramp engaging said at least one slot when said electronic register module is in said operational position and being effective for resisting movement of said electronic register module from said predetermined space.
Claim 9
Dependent Claim
81 words
An electronic register module according to claim 7 wherein said face plate includes a portion at least in the vicinity of said at least one slot which is unsecured to said frame, said portion being deformable for permitting said at least one locking ramp to pass thereunder for removal and insertion of said electronic register module and said face plate having a resilience sufficient to urge said at least one slot into locking engagement with said at least one locking ramp.
Claim 10
Dependent Claim
56 words
An electronic register module and meter frame according to claim 1 wherein said electronic register module includes at least one guide boss thereon extending toward said face plate and said face plate includes at least one slot engageable with said at least one guide boss during insertion of said electronic register module into said meter frame.
