Abstract
Abstract A rail assembly which includes an elongated, rigid supporting member having formed on one side thereof, at least one elongated, bumper strip receiving channel. Bumper strips are mounted in said channels to provide a cushion upon impact to one side of said bumper strips. The assembly further includes a plurality of mounting brackets having a base portion adapted for securement by fastening devices to a wall, and having web means extending between the base portion and a mounting portion which is adapted for securement to the elongated supporting member. The mounting portion includes a flange having a bolt aperture therein for receiving a bolt which is passed through a slot or groove formed in one side of the elongated, rigid supporting member. The slot communicates with a channel defined by the elongated supporting member, which channel accommodates a plurality of nuts positioned for engagement with bolts extended through the bolt apertures in the flanges. The mounting portion of the brackets further includes a surface which is geometrically configured to engage a second slot or groove formed in the elongated, rigid supporting member, and to cooperate with the bolts in mounting the supporting member in a desired location in spaced relation to a wall. The rail assembly may be employed either as a protective shock absorbing wall rail or as a hand rail.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
272 words
A rail assembly comprising: a hollow, elongated, rigid supporting member having at least one bumper strip receiving channel on one side thereof, having an elongated groove in another side thereof and extending substantially parallel to the bumper strip receiving channel, and having formed therein, a nut-receiving channel for slidably receiving nuts, said nut-receiving channel having a slot opening thereinto through said rigid supporting member and extending over the length of said nut-receiving channel, said supporting member completely enclosing said nut-receiving channel except for said slot opening thereinto; a plurality of polygonally shaped nuts slidably positioned in said nut-receiving channel in a position preventing rotation of said nuts in said channel; a resilient bumper strip mounted in and protruding from each of said bumper strip receiving channels; a plurality of mounting brackets for positioning said supporting member in spaced relation to a wall, said mounting brackets each including: a base portion adapted for securement to a wall; a mounting portion adapted for securement to said rigid supporting member; and web means extending between and interconnecting said base portion and said mounting portion; said mounting portion being further characterized in including: a flange having a bolt aperture therethrough for receiving a bolt extending through said slot into said nut-receiving channel; and a surface complementary in configuration to said elongated groove for mating with and detachably engaging said groove; and bolts extending through said bolt receiving apertures in the mounting portions of said mounting brackets and engaging said polygonally shaped nuts, said bolts cooperating with said engaged groove and complementary surface for retaining said rigid supporting member in a selected position on said mounting brackets.
Claim 2
Dependent Claim
272 words
A rail assembly comprising: a hollow, elongated, rigid supporting member having at least one bumper strip receiving channel on one side thereof, having an elongated groove in another side thereof and extending substantially parallel to the bumper strip receiving channel, and having formed therein, a nut-receiving channel for slidably receiving nuts, said nut-receiving channel having a slot opening thereinto through said rigid supporting member and extending over the length of said nut-receiving channel, said supporting member completely enclosing said nut-receiving channel except for said slot opening thereinto; a plurality of polygonally shaped nuts slidably positioned in said nut-receiving channel in a position preventing rotation of said nuts in said channel; a resilient bumper strip mounted in and protruding from each of said bumper strip receiving channels; a plurality of mounting brackets for positioning said supporting member in spaced relation to a wall, said mounting brackets each including: a base portion adapted for securement to a wall; a mounting portion adapted for securement to said rigid supporting member; and web means extending between and interconnecting said base portion and said mounting portion; said mounting portion being further characterized in including: a flange having a bolt aperture therethrough for receiving a bolt extending through said slot into said nut-receiving channel; and a surface complementary in configuration to said elongated groove for mating with and detachably engaging said groove; and bolts extending through said bolt receiving apertures in the mounting portions of said mounting brackets and engaging said polygonally shaped nuts, said bolts cooperating with said engaged groove and complementary surface for retaining said rigid supporting member in a selected position on said mounting brackets.
Claim 3
Dependent Claim
31 words
A rail assembly as defined in claim 1 wherein said elongated groove is substantially V-shaped in cross section, and said surface of said mounting portion is substantially V-shaped in cross section.
Claim 4
Dependent Claim
86 words
A rail assembly as defined in claim 1 wherein said bumper strip receiving channel is substantially rectangular in configuration and open at one side thereof; and wherein said bumper strip is a flexible, resilient strip having opposite side edges positioned in said bumper strip receiving channel, and a central portion protruding from said bumper strip receiving channel through the open side thereof, said central portion of said bumper strip defining an air space with said elongated, rigid supporting member, and within said bumper strip receiving channel.
Claim 5
Dependent Claim
23 words
A rail assembly as defined in claim 1 wherein said slot is dimensioned to prevent passage of nuts therethrough from said nut-receiving channel.
Claim 6
Dependent Claim
46 words
A rail assembly as defined in claim 1 wherein said web means includes a pair of legs, one of said legs having said flange of the mounting portion projecting therefrom, and the other of said legs having said groove-engaging surface of said mounting portion projecting therefrom.
Claim 7
Dependent Claim
67 words
A rail assembly as defined in claim 1 wherein said elongated groove in said rigid supporting member is spaced vertically upward on said rigid supporting member from said nut receiving channel, and engages said surface of said mounting portion to prevent movement of said rigid supporting member toward and away from a wall to which said rigid supporting member is mounted by means of said mounting brackets.
Claim 8
Dependent Claim
19 words
A rail assembly as defined in claim 1 wherein each of said mounting brackets is substantially U-shaped in configuration.
Claim 9
Dependent Claim
25 words
A rail assembly as defined in claim 1 wherein said nut-receiving channel is open at its opposite ends to facilitate the placement of nuts therein.
