Abstract
Abstract The crossover unit includes a polyurethane pad having a slot extending downwardly and then laterally or horizontally beneath an overhanging lip. A wedge-shaped rubber insert or plug is received in the slot which not only closes the slot, but also resists deflection of the lip when heavy vehicles traverse the unit so that sufficient space is maintained beneath the lip for the protective accommodation of an electric power cable or hose. In a second embodiment the slot extends in opposite lateral directions between a pair of overhanging lips, the insert in this instance being received between the two lips so that space exists under the lips for two cables or hoses.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
155 words
A crossover unit comprising an elongated pad of resilient material having top, bottom and inclined surfaces, said pad having a longitudinally directed slot therein extending downwardly from said top surface and laterally toward one side of said pad to provide an integral lip having a generally vertical free edge with the lateral portion of said slot residing beneath said lip, and an insert received in said slot, said insert engaging the free edge of said lip, a portion of the pad at the opposite side of said slot, as well as a portion of the pad at the bottom of said slot, the top of the insert being adjacent the top surface of said pad and said insert reducing the downward deformation of said lip due to a load on the top surface of the unit so that an elongated member such as a cable can be accommodated in the lateral portion of said slot.
Claim 2
Dependent Claim
155 words
A crossover unit comprising an elongated pad of resilient material having top, bottom and inclined surfaces, said pad having a longitudinally directed slot therein extending downwardly from said top surface and laterally toward one side of said pad to provide an integral lip having a generally vertical free edge with the lateral portion of said slot residing beneath said lip, and an insert received in said slot, said insert engaging the free edge of said lip, a portion of the pad at the opposite side of said slot, as well as a portion of the pad at the bottom of said slot, the top of the insert being adjacent the top surface of said pad and said insert reducing the downward deformation of said lip due to a load on the top surface of the unit so that an elongated member such as a cable can be accommodated in the lateral portion of said slot.
Claim 3
Dependent Claim
81 words
A crossover unit in accordance with claim 1 in which said slot also has a portion extending laterally toward the other side of said pad to provide a second integral lip having a generally vertical free edge, said last-mentioned free edge constituting the portion at the opposite side of said slot which is engaged by said insert, whereby a second elongated member such as a cable can be accommodated in the lateral portion of said slot residing beneath said second lip.
Claim 4
Dependent Claim
25 words
A crossover unit in accordance with claim 2 in which said insert is wider at its top than at its bottom, thereby providing converging sides.
Claim 5
Dependent Claim
17 words
A crossover unit in accordance with claim 3 in which said insert is longer than said pad.
Claim 6
Dependent Claim
28 words
A crossover unit in accordance with claim 3 in which said free edges have a slope corresponding to the degree of convergence of the sides of said insert.
Claim 7
Dependent Claim
28 words
A crossover unit in accordance with claim 5 including a pair of parallel ribs at the bottom of said slot for receiving the bottom of said insert therebetween.
Claim 8
Dependent Claim
30 words
A crossover unit in accordance with claim 6 in which said parallel ribs have sloping surfaces possessing a degree of convergence corresponding to that of the sides of said insert.
Claim 9
Dependent Claim
18 words
A crossover unit in accordance with claim 1 in which said pad and insert are of elastomeric material.
Claim 10
Dependent Claim
27 words
A crossover unit in accordance with claim 8 in which the elastomeric material constituting said pad is polyurethane and the elastomeric material constituting said insert is rubber.
