Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
437 words
A surface mounted hinged wiring raceway comprising: a an elongated back member including: 1 an elongated thin back portion having a flat back surface adapted to be mounted against a wall, a front surface, and first and second opposed longitudinal edges, said first longitudinal edge being adapted to abut against a surface transverse to said wall thus to align said raceway with such surface, 2 an elongated longitudinal lip extending forwardly from said front surface adjacent said second longitudinal edge, 3 an elongated retaining portion extending from said lip in a direction away from said first edge and located in a plane substantially parallel to that of said back surface, said retaining portion being spaced forwardly of said rear surface of said back member whereby to define with said wall against which said back surface lies a longitudinal first channel opening in a direction away from said first edge, said retaining portion having an edge remote from said lip and having at such edge a longitudinal guide portion sloping in a direction forwardly and towards said first edge, 4 a longitudinal foot extending forwardly from said front surface of said back portion, said foot being spaced from said first edge towards said second edge by a predetermined distance, said foot having a longitudinal stepped portion spaced forwardly of said front surface, said stepped portion defining with said front surface a longitudinal second channel opening in a direction away from said second edge, said stepped portion including a second longitudinal lip extending forwardly from said channel, b an elongated front cover having a first longitudinal edge, c an elongated flexible bead member sealed permanently to said second longitudinal lip and to said first longitudinal edge of said front cover so that said front cover and said back member form a single integral unit and so that said front cover may pivot relative to said back member about said bead member, d said front cover including an elongated web portion extending in a direction towards said first edge of said front cover, said web portion being adapted to slide over said guide portion of said back member and to snap into said first channel when said cover is pivoted about said bead member to carry said web portion towards said guide portion, e said front cover including an elongated tapered flange protruding beyond said web member and sloping in a direction away from said first edge of said front cover, said elongated tapered flange being adapted to press against said wall when said cover is closed whereby to seal said first channel against entry of dust and dirt therein.
Claim 2
Dependent Claim
437 words
A surface mounted hinged wiring raceway comprising: a an elongated back member including: 1 an elongated thin back portion having a flat back surface adapted to be mounted against a wall, a front surface, and first and second opposed longitudinal edges, said first longitudinal edge being adapted to abut against a surface transverse to said wall thus to align said raceway with such surface, 2 an elongated longitudinal lip extending forwardly from said front surface adjacent said second longitudinal edge, 3 an elongated retaining portion extending from said lip in a direction away from said first edge and located in a plane substantially parallel to that of said back surface, said retaining portion being spaced forwardly of said rear surface of said back member whereby to define with said wall against which said back surface lies a longitudinal first channel opening in a direction away from said first edge, said retaining portion having an edge remote from said lip and having at such edge a longitudinal guide portion sloping in a direction forwardly and towards said first edge, 4 a longitudinal foot extending forwardly from said front surface of said back portion, said foot being spaced from said first edge towards said second edge by a predetermined distance, said foot having a longitudinal stepped portion spaced forwardly of said front surface, said stepped portion defining with said front surface a longitudinal second channel opening in a direction away from said second edge, said stepped portion including a second longitudinal lip extending forwardly from said channel, b an elongated front cover having a first longitudinal edge, c an elongated flexible bead member sealed permanently to said second longitudinal lip and to said first longitudinal edge of said front cover so that said front cover and said back member form a single integral unit and so that said front cover may pivot relative to said back member about said bead member, d said front cover including an elongated web portion extending in a direction towards said first edge of said front cover, said web portion being adapted to slide over said guide portion of said back member and to snap into said first channel when said cover is pivoted about said bead member to carry said web portion towards said guide portion, e said front cover including an elongated tapered flange protruding beyond said web member and sloping in a direction away from said first edge of said front cover, said elongated tapered flange being adapted to press against said wall when said cover is closed whereby to seal said first channel against entry of dust and dirt therein.
Claim 3
Dependent Claim
42 words
A raceway according to claim 1 wherein said back member and said front cover are formed of rigid polyvinyl chloride and said bead member is formed of flexible polyvinyl chloride, said back member, front cover and bead member all being extruded together.
Claim 4
Dependent Claim
65 words
A raceway accOrding to claim 2 wherein said front cover has an elongated groove in its inner surface, said groove being located adjacent said web and located on the side of said web towards said first edge of said front cover, whereby to facilitate removal of a portion of said web to allow placement of an end cap or corner member over said front cover.
Claim 5
Dependent Claim
14 words
A raceway according to claim 3 wherein said predetermined distance is substantially 0.25 inches.
Claim 6
Dependent Claim
40 words
A raceway according to claim 1 wherein the edge of said elongated flange is formed of a flexible material sealed permanently to the remainder of said front cover, whereby said elongated flange may yield as it presses against said wall.
Claim 7
Dependent Claim
28 words
A raceway according to claim 1 wherein the width of said second channel in a front to rear direction is substantially greater than that of said first channel.
Claim 8
Dependent Claim
33 words
A raceway according to claim 1 and including a pair of spaced flange members projecting forwardly from said front surface of said back portion and forming separating means for wires in said raceway.
