Claim 7

A cover plate assembly as defined in claim 4 including a second wall portion outwardly spaced from one of said facing wall portions, said supporting means being coupled to an intermediate portion of said spring and being disposed between said one facing wall portion and said second wall portion so that the ends of said spring extend through said openings.

Claim 8

A cover plate as defined in claim 6 wherein said supporting means is generally "U" shaped, and one of the legs of said "U" comprises said intermediate portion of said spring.

Claim 9

A cover plate assembly as defined in claim 4 wherein said supporting means includes a first interlocking element on said first member, an intermediate portion of said spring being shaped to define a second interlocking element, and said first and second interlocking members cooperate to support said spring.

Claim 10

A cover plate assembly as defined in claim 1 comprising another first member, each of said first members having sides in abutting engagement with each other, means interconnecting said first members to retain said abutting sides in abutting engagement, said second member having a second aperture and extending over both of said first members, and resilient means disposed between said another first member and said second member for resiliently and releasably urging said second member against one of said facing wall portions on said other first member so that said second member is releasably retained on said first members with said apertures in said second member being aligned with the aperture in each of said first members.

Claim 11

A base plate for use in a cover plate assembly comprising a member defining a surface, said surface having an aperture through which an element can extend, said member including wall portions having facing surfaces thereon, said aperture being disposed between said facing surfaces, at least one of said wall portions having an opening therethrough, and means for supporting a spring on said member so that at least part of said spring can extend through said opening.

Claim 12

A base plate for use in a cover plate assembly comprising a member defining a surface, said surface having an aperture through which an element can extend, said member including wall portions having facing surfaces thereon, said aperture being disposed between said facing surfaces, at least one of said wall portions having an opening therethrough, and means for supporting a spring on said member so that at least part of said spring can extend through said opening.

Claim 13

A base plate as defined in claim 11 including a frame substantially surrounding said surface, the inwardly facing walls of said frame including said wall portions.

Claim 14

A base plate as defined in claim 11 including a plurality of said openings, said openings being disposed on opposite sides of the midportion of one of said facing surfaces.

Claim 15

A base plate as defined in claim 12 including a spring and, means on said spring for connecting it to said supporting means, said spring extending through some of said openings.

Claim 16

An interchangeable plate for use in a cover plate assembly comprising a rigid member defining a surface having at least one aperture through which a part of an electrical element can extend, said surface being otherwise imperforate, said member including at least two opposite edges, and a notch disposed along each of said opposite edges for engagement with corresponding projecting means on said assembly.

Claim 17

An interchangeable plate for use in a cover plate assembly comprising a rigid member defining a surface having at least one aperture through which a part of an electrical element can extend, said surface being otherwise imperforate, said member including at least two opposite edges, and a notch disposed along each of said opposite edges for engagement with corresponding projecting means on said assembly.

Claim 18

An interchangeable plate as defined in claim 14 wherein one of said notches is disposed intermediate the ends of one of said edges.

Claim 19

An interchangeable plate as defined in claim 15 wherein said surface comprises a decorative design.

Claim 20

A cover plate assembly comprising a plurality of first members and a second member, each of said first members having an aperture through which an element can extend and including wall portions having facing surfaces thereon, said aperture in each of said first members being disposed between said facing surfaces, each of said first members having a side edge in abutting engagement with the side edge of an adjoining first member and means to retain said abutting side edges in abutting engagement, said second member having at least two opposite edges and being supported on said first members with a portion of each of said opposite edges adjacent each of said facing surfaces, said second member having a plurality of apertures through which elements can extend, and resilient means disposed between said first and second members for resiliently and releasably urging said second member against one of said facing surfaces of each of said first members so that said second member is releasably retained on said first members with said apertures in said first members being aligned with said apertures in said second member.

Claim 21

A cover plate assembly comprising a plurality of first members and a second member, each of said first members having an aperture through which an element can extend and including wall portions having facing surfaces thereon, said aperture in each of said first members being disposed between said facing surfaces, each of said first members having a side edge in abutting engagement with the side edge of an adjoining first member and means to retain said abutting side edges in abutting engagement, said second member having at least two opposite edges and being supported on said first members with a portion of each of said opposite edges adjacent each of said facing surfaces, said second member having a plurality of apertures through which elements can extend, and resilient means disposed between said first and second members for resiliently and releasably urging said second member against one of said facing surfaces of each of said first members so that said second member is releasably retained on said first members with said apertures in said first members being aligned with said apertures in said second member.
