Abstract
The present disclosure provides elbow assemblies for ramp and platform assemblies, and ramp and platform assemblies. The elbow assembly includes a first elbow sub-part that is configured to nest within a second elbow sub-part. The elbow assembly includes useful features, including structure that enables direct connection either to a tubular support member or a flat portion of a support member, and structure that provides a smooth transition between the first elbow sub-part and the second elbow sub-part at any angle within the range of motion.
Claims20
An elbow assembly for a ramp and platform assembly, comprising:
- a first elbow sub-part and a second elbow sub-part that are selectably and hingeably connectable to each other by a joining device, each of the first and second elbow sub-parts having:
- a body defining a distal end, a proximal end, and a longitudinal axis extending therethrough, the body having:
- a base portion extending from the distal end to an intermediate position located between the distal end and the proximal end, the base portion being configured for insertion into a tubing member;
- and
- a connecting portion extending from the intermediate position to the proximal end, the connecting portion having:
- an arm portion extending to an end surface at the proximal end and having a first interface surface that is parallel to the longitudinal axis;
- and
- a guard portion having a first concave surface and a second concave surface that are oriented toward the arm portion, wherein a first outer edge of the first concave surface meets the arm portion at a first stop, and a second outer edge of the second concave surface meets the arm portion at a second stop;
- wherein when the first elbow sub-part is connected to the second elbow sub-part:
- the second elbow sub-part is configured to pivot relative to the first elbow sub-part within a range of motion between the first stop and the second stop;
- the first interface surface of the first elbow sub-part interfaces with the first interface surface of the second elbow sub-part;
- the end surface of the first elbow sub-part nests between the first interface surface and at least one of the first concave surface or the second concave surface of the second elbow sub-part;
- and
- the end surface of the second elbow sub-part nests between the first interface surface and at least one the first concave surface or the second concave surface of the first elbow sub-part.

A ramp and platform assembly, comprising:
- a platform section having a walking surface;
- a ramp section having a first end and a second end, the first end being connected to the platform section;
- a first support member supported by at least one of the platform section or the ramp section;
- a second support member;
- and
- a first elbow assembly connecting the first support member to the second support member, the first elbow assembly comprising:
- a first elbow sub-part and a second elbow sub-part that are selectably and hingeably connectable to each other by a joining device, each of the first and second elbow sub-parts having:
- a body defining a distal end, a proximal end, and a longitudinal axis extending therethrough, the body having:
- a base portion extending from the distal end to an intermediate position located between the distal end and the proximal end, the base portion being configured for insertion into a tubing member;
- and
- a connecting portion extending from the intermediate position to the proximal end, the connecting portion having:
- an arm portion extending to an end surface at the proximal end and having a first interface surface that is parallel to the longitudinal axis;
- and
- a guard portion having a first concave surface and a second concave surface that are oriented toward the arm portion, wherein a first outer edge of the first concave surface meets the arm portion at a first stop, and a second outer edge of the second concave surface meets the arm portion at a second stop;
- wherein when the first elbow sub-part is connected to the second elbow sub-part, the second elbow sub-part is configured to pivot relative to the first elbow sub-part within a range of motion between the first stop and the second stop, the first interface surface of the first elbow sub-part interfaces with the first interface surface of the second elbow sub-part, the end surface of the first elbow sub-part nests between the first interface surface and at least one of the first concave surface or the second concave surface of the second elbow sub-part, and the end surface of the second elbow sub-part nests between the first interface surface and at least one the first concave surface or the second concave surface of the first elbow sub-part,
- wherein the base portion of the first elbow sub-part is joined with the first support member and the base portion of the second elbow sub-part is joined with the second support member.
