Description
2~83993 This invention relates to conduits and ramps for the protection of electrical wires and conductors.
There are many instances where electrical wires and conductors are to be placed in exposed locations, but which need to be protected. Thus, there are instances where electrical cables are temporarily placed on a floor to conduit electricity from an outlet to a bank of lights. Another instance is the laying of electrical wires and conductors between two spaced-apart locations.
In both these instances, it is important for safety reasons that the electrical wires and conductors be undisturbed by vehicular and pedestrian traffic.
Accordingly, it is an object of one aspect of this invention to provide a conduit for electrical wires and conductors within which those wires and conductors may be easily disposed in an essentially tamper-proof manner.
An object of another aspect of this invention is the provision of a ramp for electrical wires and conductors which may be placed atop such wires and conducto:rs to protect them from vehicular and pedestrian traffic.
By one broad aspect of this invention a two-piece generally tamper-proof protective conduit is provided for electrical wires or cables, comprising a generally tamper-proof protective conduit for electrical wires or cables comprising: a generally rectangular but U-shaped, longitudinally-extending profile, the inner faces at the terminal ends of the legs of the "U" each being provided with an associated one of a pair of opposed lateral internal, longitudinally-extending lips; and a 2 20~39~3 longitudinally-extending cover plate having a pair of lateral facings, longitudinally-extending stepped shoulders, each shoulder terminating in a respective projecting, generally semi-circular in cross-section, longitudinally-extending flexural walls.
The profile is of rectangular cross-section, e.g. square.
In either case, the lips preferably taper to a common longitudinally-extending edge and/or the terminal ends of the flexural walls taper to a common longitudinally-extending edge.
The upper surface of the cover plate may be gently convexly curved, or planar.
By another aspect of this invention, a ramp is provided for protecting electrical wires or conduits comprising a hollow, longitudinally-extending member, the upper surface of which iCi generally partially circular curved shape, the lower floor being generally planar, and a longitudinally-extending open pocket extending between a gap in the lower generally planar floor and the curved upper surface. -~
The ramp preferably includes a pair of longitudinally-extending generally triangular in cross-section sealed lateral chambers, and the open pocket is a central chamber.
Preferably also, the ramp includes a plurality of lateral, longitudinally-extending ridges along the generally planar lower - ~
floor. -In the accompanying drawings, Figure 1 is an exploded perspective cross-sectional view of one embodiment of a conduit according to one aspect of this invention;
20839~3 Figure 2 is an exploded perspective cross-sectional view of a second embodiment of a conduit according to another aspect of this invention; and Figure 3 is a perspective cross-sectional view of the ramp of yet another aspect of this invention.
As seen in Figure 1, the embodiment of the conduit 10 includes, as one element thereof, a generally square but U-shaped profile 20 having a principal wall 21 and two side walls 22, 23.
The wall 24 opposed to the principal wall 20 is open and is provided by a pair of inwardly directed lateral lips 25, 26 whose purpose will be described hereinafter.
The second element thereof is a cover extrusion 40 including a gently outwardly curved principal wall 41 and a pair of semi-circular lateral flexural walls 42, 43 .integral therewith. The opposite face of the principal wall 41 include a pair of lateral stepped shoulders 45, 46.
As seen in Figure 2 the embodiment of the conduit 50 includes, as one element thereof, a generally square profile but U-shaped 60 having a principal wall 61 and two side walls 62, 63.
The wall 64 opposed to the principal wall 60 is open and is provided by a pair of inwardly directed lateral lips 65, 66 whose purposes will be described hereinafter.
The second element thereof is a cover extrusion 70 including a planar principal wall 71 and a pair of semi-circular lateral flexural walls 72, 73 integral therewith. The opposite faces of the principal wall 71 include a pair of lateral stepped shoulders 75, 76.
2~83~3 In operation of the embodiments of Figures 1 and 2, one electrical wire or cable (as in the case of Figure 1~ are a pair of electrical wires or cables (as in the case of Figure 2) are placed within the square or rectangular profile. Then the cover extrusion is "snapped~' into place, the snapping being by way of flexure of the flexural walls around the lateral lips. The upper ends of the flexural walls at the region of the stepped shoulders are gripped by the lateral lips to prevent lifting off of the cover extrusion.
If need be, however, the cover extension may be removed by a relative longitudinal sliding motion.
As seen in Figure 3 the ramp 100 includes a main, partial circular upper face 10 and a split lower flat floor 102, 103 provided with a gap 109. The lateral portions of the ramp are lS provided by a respective pair of sealed, g~nerally-triangular-in-cross-section chambers 104, 105 by means of walls 106, 107. The central portion is provided by a generally-rectangular-in-cross-section, open chamber 108~
In use the electrical wire or cable is laid on the ground.
The ramp is then laid thereover, with the central chamber accommodating the wire or cable, entry being permitted by the gap.
