Abstract

Abstract In a direct current electronic digital platform scale with a base and a movable cover thereover, a weight-responsive system in the base has electronic structure connected to convert cover movement to a digital weight readout. A switch is provided that is closed by cover movement to activate the electronic structure and the readout, and a convenient 9 volt battery is supported in the base and wired to supply power to the switch and electronic structure to indicate weight. To this general arrangement, an improvement in the battery support has an opening through the base to the interior and a box-like molded plastic battery receptacle is supported in the opening with the box extending into the base. A second opening through the receptacle inside the base permits the wires to connect to a battery harness inside the receptacle and a matching box or receptacle cover is latchably connected to secure the cover to the base and close off the receptacle such that the cover is flush with or coplanar with the base. This provides a convenient, inexpensive, easily assembled, common arrangement for renewing the battery in the base of the electronic platform scale from outside.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 168 words
In a DC electronic digital platform scale having a base and movable cover thereover, a weight-responsive system in the base with electronic means connected to convert cover movement to a digital weight readout, a switch closed by cover movement activating said means and readout, and a battery supported in the base connectively wired to supply power through said switch and said means to indicate weight, an improvement in the battery support comprising, an opening through the base to its interior, a battery receptacle comprising a walled box peripherally supported by and extending totally within said base, said opening extending through a wall of said box for said wire connection, matching box cover means coplanar with the plane of said base and latchably securing thereto in said coplanar plane, said receptacle comprising a single integral molded plastic with said cover being attached thereto with a living hinge, whereby a battery is removably supported and connected in the receptacle within the base and accessible outside the scale through said cover.
Claim 2
Dependent Claim 168 words
In a DC electronic digital platform scale having a base and movable cover thereover, a weight-responsive system in the base with electronic means connected to convert cover movement to a digital weight readout, a switch closed by cover movement activating said means and readout, and a battery supported in the base connectively wired to supply power through said switch and said means to indicate weight, an improvement in the battery support comprising, an opening through the base to its interior, a battery receptacle comprising a walled box peripherally supported by and extending totally within said base, said opening extending through a wall of said box for said wire connection, matching box cover means coplanar with the plane of said base and latchably securing thereto in said coplanar plane, said receptacle comprising a single integral molded plastic with said cover being attached thereto with a living hinge, whereby a battery is removably supported and connected in the receptacle within the base and accessible outside the scale through said cover.
Claim 3
Dependent Claim 44 words
Apparatus as described in claim 1 wherein said DC source is a standard 9 volt rectangular battery, a dual terminal harness connected to said wires and disposed in the box, and said receptacle box is rectangular to nest said battery substantially within said base.
Claim 4
Dependent Claim 33 words
Apparatus as described in claim 2 wherein said molded receptacle box has oppositely-facing projections on opposing walls abutting opposite base surfaces for snapping the box into the base opening to lock it therein.
