Abstract

Abstract An adaptable telephone baseplate can be used for either wall mounting or desk or table top mounting. The baseplate has an enclosed recess at an intermediate position and a modular jack position at what would be the top edge when wall mounted. A slot connects the jack position and enclosed recess. When wall mounted a short cord can be inserted in the slot with a plug at one end being inserted in the jack at the jack position and a plug at the other end being in the recess for insertion into a wall jack. When desk mounted a normal line cord enters through a groove into the jack position for insertion of a plug into a jack. Alternatively a line cord can enter through the groove, extend along the slot and then pass up through the slot for hard wiring of the conductors to a circuit board. Snap-in mountings are provided for the jack, a circuit board, ringer and possibly other items. For some telephones a battery housing can be provided while in others the battery housing can be omitted, by the alternative use of two inserts in the mold for the baseplate.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 217 words
An adaptable telephone baseplate for alternative wall and desk top mounting, comprising: a base member and a peripherally extending rim on the base member extending upwardly from a top surface on the base member; an enclosed recess extending from a bottom surface of the base member up through the base member and upwardly of said top surface, for positioning of a modular wall mounting plug therein, said recess being defined by a first aperture in said base member, upwardly extending side walls around the periphery of said first aperture and a top wall extending between said side walls at a position above said base member, said top and side walls enclosing said recess from the remainder of the top surface of said base member; modular jack mounting means at a top end of the base member, said modular jack mounting means being aligned with a second aperture through the base member for insertion of a modular line cord plug through said second aperture and into a jack mounted at said mounting means; a slot in said base member extending from said enclosed recess to said second aperture, for insertion of a short cord between said modular wall mounting plug and a further modular plug adapted for insertion into said jack for wall mounting of the baseplate; and
Claim 2
Dependent Claim 217 words
An adaptable telephone baseplate for alternative wall and desk top mounting, comprising: a base member and a peripherally extending rim on the base member extending upwardly from a top surface on the base member; an enclosed recess extending from a bottom surface of the base member up through the base member and upwardly of said top surface, for positioning of a modular wall mounting plug therein, said recess being defined by a first aperture in said base member, upwardly extending side walls around the periphery of said first aperture and a top wall extending between said side walls at a position above said base member, said top and side walls enclosing said recess from the remainder of the top surface of said base member; modular jack mounting means at a top end of the base member, said modular jack mounting means being aligned with a second aperture through the base member for insertion of a modular line cord plug through said second aperture and into a jack mounted at said mounting means; a slot in said base member extending from said enclosed recess to said second aperture, for insertion of a short cord between said modular wall mounting plug and a further modular plug adapted for insertion into said jack for wall mounting of the baseplate; and
Claim 3
Dependent Claim 78 words
at least two mounting apertures in said base member, each said mounting aperture of keyhole formation and comprising a circular aperture portion and a waisted slot portion, the slot portion narrower than the diameter of the circular aperture portion and positioned above the circular aperture portion when the baseplate is in a wall mounting position, said waisted slot portion defined by two spaced resilient members for producing a snap fit on a mounting stud attached to a wall.
Claim 4
Dependent Claim 78 words
at least two mounting apertures in said base member, each said mounting aperture of keyhole formation and comprising a circular aperture portion and a waisted slot portion, the slot portion narrower than the diameter of the circular aperture portion and positioned above the circular aperture portion when the baseplate is in a wall mounting position, said waisted slot portion defined by two spaced resilient members for producing a snap fit on a mounting stud attached to a wall.
Claim 5
Dependent Claim 22 words
A baseplate as claimed in claim 1, including bridging members extending over said slot on said top surface of said base member.
Claim 6
Dependent Claim 37 words
A baseplate as claimed in claim 1, including a ringer mounting position on said base member, and resilient snap members extending up from the top surface at said ringer mounting position for retaining a ringer in position.
Claim 7
Dependent Claim 39 words
A baseplate as claimed in claim 1, including a plurality of resilient snap members extending upwards from said top surface of the base member, said snap members positioned to retain a circuit board in position on said base member.
Claim 8
Dependent Claim 45 words
A baseplate as claimed in claim 1, said resilient members each comprising a first arcuate portion defining part of the circumference of the circular aperture portion and an end portion curved round and outwards whereby the two spaced resilient members present convex surfaces in opposition.
Claim 9
Dependent Claim 28 words
A baseplate as claimed in claim 5, each mounting aperture including a semicircular portion on the opposite side of said waisted slot portion to said circular aperture portion.
Claim 10
Dependent Claim 13 words
A baseplate as claimed in claim 1, said slot being of sinuous form.
Claim 11
Dependent Claim 80 words
A baseplate as claimed in claim 1, said modular jack means offset to one side of said base member at said top end, said enclosed recess positioned downwardly from said top edge towards the centre of the base member, said slot of sinuous form ending at one end at an opening in a side wall of the enclosed recess and ending at the other end at an opening in a side wall forming part of said modular jack mounting means.
Claim 12
Dependent Claim 67 words
A baseplate as claimed in claim 1, including a further aperture through said base member, walls extending around said aperture on the top surface of said base member to define a battery receiving housing, a plurality of ribs extending across said housing from top edges of said walls, and a cover slidingly received in said aperture to close said aperture and retain a battery in said housing.
