Abstract

A loading ramp includes first and second ramp portions that are coupled by a hinge assembly such that the first and second ramp portions are movable relative to one another between an extended position and a folded position. The loading ramp also has one or more lights coupled to one of the ramp portions and a switch assembly coupled to the ramp portions such that in the extend position the switch assembly is activated to illuminate the one or more lights.

Claims

1. A loading ramp comprising:

a first ramp portion;

a second ramp portion;

a hinge assembly coupling the first and second ramp portions such that the first and second ramp portions are movable relative to one another between an extended position and a folded position;

a switch assembly having a first portion coupled to the first ramp portion and a second portion coupled to the second ramp portion, the first and second portions configured to engage or be in close proximity to one another in the extended position and disengage in the folded position;

at least one first LED strip light coupled to and extending along a length of the first ramp portion, the at least one first LED strip light being operatively coupled to the first portion of the switch assembly to be switchable between an on state when the first and second portions are engaged or in close proximity to one another and an off state when the first and second portions are moved away from one another; and

at least one second LED strip light coupled to and extending along a length of the second ramp portion, the at least one second LED strip light being operatively coupled to the first portion of the switch assembly to be switchable between an on state when the first and second portions are engaged or in close proximity to one another and an off state when the first and second portions are moved away from one another,

wherein in the extended position the first and second portions of the switch assembly engage or are in close proximity to one another to illuminate the first and second LED strip lights, and in the folded position the first and second portions of the switch assembly are moved away from one another to turn off the first and second LED strip lights,

wherein the first and second LED strip lights extend through one or more channels formed in the respective first and second ramp portions at top surfaces thereof, and

wherein the one or more channels extend along the lengths of the first and second ramp portions and open to a bottom surface of the respective first and second ramp portions.

2. The loading ramp according to claim 1, further including a power source coupled to one of the first or second ramp portions, wherein the power source is operatively coupled to the switch assembly and the first and second LED strip lights to power the LED strip lights.

3. The loading ramp according to claim 2, wherein the power source is a battery hub coupled to a bottom surface of one of the first or second ramp portions.

4. The loading ramp according to claim 2, wherein the first and second LED strip lights are operatively coupled to the first portion of the switch assembly by a respective wire, the first and second LED strip lights are operatively coupled to the power source by a respective wire, and the power source is operatively coupled to the switch assembly by a wire.

5. The loading ramp according to claim 1, wherein the first and second portions of the switch assembly each have a face substantially perpendicular to top surfaces of the first and second ramp portions, and wherein the faces are configured to engage or be in close proximity to one another in the extended position.

6. The loading ramp according to claim 1, wherein the first portion of the switch assembly is a reed switch and the second portion is a magnet.

7. The loading ramp according to claim 1, wherein the first portion of the switch assembly is a pressure switch and the second portion is a pedal.

8. The loading ramp according to claim 1, wherein the first ramp portion includes a first rail portion and a first tread portion having a tread opening through which the first rail portion extends and a channel through which the at least one first LED strip light extends, and wherein the second ramp portion includes a second rail portion and a second tread portion having a tread opening through which the second rail portion extends and a channel through which the at least one second LED strip light extends.

9. The loading ramp according to claim 8, wherein each channel opens towards the respective tread opening, and wherein the first and second rail portions trap the first and second LED strip lights in the respective channels.

10. The loading ramp according to claim 8, further including an L-shaped portion coupled to or integrally formed with the first rail portion and extending through the channel with the first LED strip light, and an L-shaped portion coupled to or integrally formed with the second rail portion and extending through the channel with the second LED strip light.

11. A loading ramp comprising:

a first ramp portion Including a first rail portion and a plurality of first tread portions removably attached to the first rail portion and having a top surface forming a support surface to support a load of a vehicle, each of the first tread portions including at least one channel extending along a length of the respective first tread portion along the top surface;

a second ramp portion including a second rail portion and a plurality of second tread portions removably attached to the second rail portion and having a top surface forming a support surface to support the load of the vehicle, each of the second tread portions including at least one channel extending along a length of the respective second tread portion along the top surface;

a hinge assembly coupling the first and second ramp portions such that the first and second ramp portions are movable relative to one another between an extended position and a folded position;

at least one first strip light coupled to the first ramp portion and extending through the at least one channel of each of the first tread portions;

at least one second strip light coupled to the second ramp portion and extending through the at least one channel of each of the second tread portions;

a switch assembly having a first portion coupled to the first ramp portion and a

second portion coupled to the second ramp portion, the switch assembly being operatively coupled to the at least one first and second strip lights and the first and second portions configured to engage or be in close proximity to one another in the extended position and disengage in the folded position,

wherein in the extended position the at least one first and second strip lights are activated, and in the folded position the at least one first and second tip lights are deactivated.

12. The loading ramp according to claim 11, further including a power source coupled to one of the first or second ramp portions, wherein the power source is operatively coupled to the first and second lights to power the lights.

13. The loading ramp according to claim 11, wherein the first and second ramp portions each include one or more channels opening to a top surface of each portion for receiving the at least one first or second light respectively.

14. The loading ramp according to claim 11, wherein the first strip light is a first LED strip light and the second strip light is a second LED strip light.

15. The loading ramp according to claim 11, wherein each of the first and second tread portions has the top surface and a bottom surface, and wherein each channel in each of the first and second tread portions opens towards the respective bottom surface.

16. The loading ramp according to claim 11, wherein the at least one channel extending along the length of each of the first tread portions includes a pair of channels extending along the length of each of the first tread portions and being spaced from one another along a width of the respective first tread portion, wherein the at least one first strip light includes a pair of first strip lights each extending through one of the pair of channels of each of the first tread portions, wherein the at least one channel extending along the length of each of the second tread portions includes a pair of channels extending along the length of each of the second tread portions and being spaced from one another along a width of the respective second tread portion, and wherein the at least second first strip light includes a pair of second strip lights each extending through one of the pair of channels of each of the second tread portions.
