Telescoping pet ramp
View Patent ↗A telescoping pet ramp having first and second ramp segments telescopically extendable from a compact state to an extended state. Side rails of the panels include end caps with abutment members for preventing the first floor panel and second floor panel from being separated when the pet ramp is fully extended, and including interlocking angled contact faces that frictionally engage one another when the ramp is fully extended.
1. An extensible ramp comprising:
a first ramp segment comprising a first floor panel and a first rail extending along a lateral side of the first floor panel, the first rail having a first abutment member substantially contained therein and affixed at a proximal end thereof; and
a second ramp segment comprising a second floor panel and a second rail extending along a lateral side of the second floor panel, the second rail having a second abutment member affixed at a proximal end thereof, the second abutment member being substantially contained within the first rail, and the second ramp segment being telescopically slidable relative to the first ramp segment between a compact position and an extended position;
wherein the first and second abutment members releasably engage one another in the extended position.
2. The extensible ramp of claim 1 , wherein the first and second abutment members comprise obliquely angled contact faces.
3. The extensible ramp of claim 2 , wherein the obliquely angled contact faces define compound angles.
4. The extensible ramp of claim 1 , wherein the first and second abutment members comprise contact surfaces defining a first angle of inclination in a first dimension and a second angle of inclination in a second dimension.
5. The extensible ramp of claim 1 , wherein the first and second floor panels comprise blow-molded plastic.
6. The extensible ramp of claim 1 , wherein the first and second rails comprise glass fiber reinforced plastic.
7. The extensible ramp of claim 1 , wherein the first and second floor panels comprise a frictional tread surface for permitting a pet to climb thereon.
8. The extensible ramp of claim 1 , wherein the second rail is slidingly received within an elongate channel in the first rail.
9. A pet ramp comprising:
a first member comprising a first floor panel with first side rails extending along lateral sides thereof;
a second member comprising a second floor panel with second side rails extending along lateral sides thereof, the second member being telescopically extendable relative to the first member;
wherein the first and second floor panels comprise blow-molded plastic and wherein the first and second side rails comprise glass fiber reinforced plastic; and
wherein the side rails of the first panel comprise first endcaps having a first obliquely angled surface, and wherein the side rails of the second panel comprise second endcaps having a second obliquely angled surface, and wherein the first and second obliquely angled surfaces engage one another in the extended position.
10. The pet ramp of claim 9 , wherein the floor panels of the first and second members comprise a frictional contact surface.
11. The pet ramp of claim 9 , wherein the first and second obliquely angled surfaces each comprise a first angle of inclination in a first plane, and a second angle of inclination in a second plane orthogonal to the first plane.
12. A pet ramp comprising:
a first ramp segment comprising a first endcap and a first abutment member having an obliquely angled first contact face, the first abutment member being substantially contained within the first endcap; and
a second ramp segment comprising a second endcap and a second abutment member having an obliquely angled second contact face, the second abutment member being substantially contained within the second endcap,
wherein the second ramp segment is translationally extensible relative to the first ramp segment to bring the first contact face into engagement with the second contact face.
13. The pet ramp of claim 12 , wherein the first and second contact faces define compound angles.
14. The pet ramp of claim 12 , wherein the first and second contact faces define a first angle of inclination in a first dimension, and a second angle of inclination in a second dimension orthogonal to the first dimension.
15. The pet ramp of claim 12 , wherein the first and second ramp segments comprise floor panels formed of blow-molded plastic.
16. The pet ramp of claim 15 , wherein the floor panels comprise a frictional contact surface.
17. The pet ramp of claim 12 , wherein the first and second ramp segments comprise side rails formed of glass fiber reinforced plastic.
18. The pet ramp of claim 12 , wherein the first ramp segment comprises a first side rail, and wherein the second ramp segment comprises a second side rail slidable within the first side rail.
19. The pet ramp of claim 18 , wherein the first and second abutment members are positioned internally within the first side rail.
20. The pet ramp of claim 18 , wherein the first and second abutment members are positioned between the first side rail and the second side rail.
21. The pet ramp of claim 18 , wherein the endcaps comprise mounting flange portions having tongues comprising the first and second abutment members extending therefrom.
