Abstract
Abstract A railing includes a top member having a downwardly opening first channel with a bottom and a bottom member having an upwardly opening second channel with a top. There is a plurality of spaced-apart vertical pickets, each picket having a top end in the first channel and a bottom end in the bottom channel. There are spacers adjacent the top and bottom members. Each spacer is an elongated, continuous member with a plurality of spaced-apart openings. Each spacer has a connector engaging one of the top and bottom members. The pickets extend through the openings in the spacers. There may be resilient members along the channels. During assembly the resilient members are first fitted within the channels and the spacer members are then secured to the top and bottom members. The pickets can then be inserted through the openings in the elongated members. The elongated members are then brought towards each other and secured in place with the pickets compressing the resilient members.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
143 words
A railing, comprising: a top member having a downwardly opening first channel with a bottom; a bottom member having an upwardly opening second channel with a top; a plurality of spaced-apart vertical pickets having longitudinal axes, each said picket having sides parallel to the longitudinal axis and opposite ends and having a top end in the first channel and a bottom end in the second channel; resiliently deformable members in the channels between the ends of the pickets and the channels of the corresponding top and bottom members which bias the pickets away from the top and bottom members; and spacers adjacent the top and the bottom members, each said spacer being an elongated continuous member with a plurality of spaced-apart openings and having a connector engaging one of said top and bottom members, the pickets extending through the openings in the spacers.
Claim 2
Dependent Claim
143 words
A railing, comprising: a top member having a downwardly opening first channel with a bottom; a bottom member having an upwardly opening second channel with a top; a plurality of spaced-apart vertical pickets having longitudinal axes, each said picket having sides parallel to the longitudinal axis and opposite ends and having a top end in the first channel and a bottom end in the second channel; resiliently deformable members in the channels between the ends of the pickets and the channels of the corresponding top and bottom members which bias the pickets away from the top and bottom members; and spacers adjacent the top and the bottom members, each said spacer being an elongated continuous member with a plurality of spaced-apart openings and having a connector engaging one of said top and bottom members, the pickets extending through the openings in the spacers.
Claim 3
Dependent Claim
37 words
A railing as claimed in claim 1, wherein a first said spacer engages the bottom of the channel of the top member and a second said spacer engages the top of the channel of the bottom member.
Claim 4
Dependent Claim
27 words
A railing as claimed in claim 2, wherein the spacers are resilient and U-shaped in section with inwardly directed projections on each side thereof forming the connectors.
Claim 5
Dependent Claim
37 words
A railing as claimed in claim 3, wherein the top member and the bottom member have sides outwardly directed projections on each said side thereof, the projections of the spacers fitting over the projections of the members.
Claim 6
Dependent Claim
31 words
A railing as claimed in claim 4, wherein the resiliently deformable members are elongated and extend along the first channel above the pickets and along the second channel below the pickets.
Claim 7
Dependent Claim
16 words
A railing as claim in claim 5, wherein the resiliently deformable members are of foam plastic.
Claim 8
Dependent Claim
12 words
A railing as claimed in claim 6, wherein the foam is closed-cell.
Claim 9
Dependent Claim
17 words
A railing as claimed in claim 7, wherein the resiliently deformable members are compressed by the pickets.
Claim 10
Dependent Claim
51 words
A railing as claimed in claim 1, wherein there are spaced-apart supports including vertical open-ended posts and top post connectors connecting each said post to the top member, each said post connector including a bottom portion extending into one of the posts and a top portion connected to the top member.
Claim 11
Dependent Claim
49 words
A railing as claimed in claim 9, wherein the bottom portion of each said top post connector is a pair of spaced-apart flanges having outer projections which grip the inside of one of the posts and the top portion is a pair of co-planar flanges against the top member.
Claim 12
Dependent Claim
17 words
A railing as claimed in claim 10, including fasteners connecting the top portion to the top member.
Claim 13
Dependent Claim
42 words
A railing as claimed in claim 9, wherein the bottom member is H-shaped in section, having upper and lower pairs of parallel flanges, each of the supports having a projection supporting the bottom member and extending between one said pair of flanges.
Claim 14
Dependent Claim
15 words
A railing as claimed in claim 12, wherein the projection is between the lower flanges.
Claim 15
Independent Claim
155 words
A method of assembling railing apparatuses having an upper elongated member with a downwardly directed channel and a top surface forming the base of the channel, a lower elongated member with an upwardly directed channel and a bottom surface forming the base of the channel and a plurality of spaced-apart vertical pickets therebetween said pickets having longitudinal axes the method comprising: placing resilient members within the channels; fitting continuous spacer members to the channels, said spacer members having a plurality of spaced-apart openings, said resilient members being located between said top surface of said downwardly directed channel and a said spacer member and said bottom surface of said upwardly directed channel and a said spacer member; inserting the pickets through the openings in the spacer members against the resilient members; and bringing the elongated members towards each other so the pickets compress the resilient members in a direction along the longitudinal axes of the pickets.
Claim 16
Independent Claim
155 words
A method of assembling railing apparatuses having an upper elongated member with a downwardly directed channel and a top surface forming the base of the channel, a lower elongated member with an upwardly directed channel and a bottom surface forming the base of the channel and a plurality of spaced-apart vertical pickets therebetween said pickets having longitudinal axes the method comprising: placing resilient members within the channels; fitting continuous spacer members to the channels, said spacer members having a plurality of spaced-apart openings, said resilient members being located between said top surface of said downwardly directed channel and a said spacer member and said bottom surface of said upwardly directed channel and a said spacer member; inserting the pickets through the openings in the spacer members against the resilient members; and bringing the elongated members towards each other so the pickets compress the resilient members in a direction along the longitudinal axes of the pickets.
