    Tube clamps to fit wheelchair tubing - modular detachable



    Going on a Tilite TR Titanium - tube is OD(outside diameter 1") : as compared to aluminum quickie OD (1 1/8") and Quickie aluminum All court OD(1 1/4").

    Before I re-invent the wheel, figured I would see if anyone had found a good source or solution or any ideas welcome at this point.

    I'm looking for aluminum clamps to fit to my chair tubing that would allow me to connect a temporary tubular frame. Thinking the anchor points could be left on the chair and then the frame snapped into place when I want to use it.

    Figured this would be good for many things, table/desk that doesn't rest on your legs, so they could spasm and you wouldn't worry about the weight on your legs as the frame would take the weight.

    My project is to fashion a frame that would accept a child car seat.

    Similar to this frame but imagine it being fixed to my front tubes above the casters, and hence no need for the stroller




    This seems like an excellent start, but I don't have the luxury of being able to slide the clamp onto the tube, it has to be hinged, or have two bolts. seems like a great start though.

    Similar to this.. but I need the clamping to run parallel and not perpendicular

    This mechanism would be awesome.. if it was made into the double clamp above.

    The Tilite luggage carrier .... will only slide up the lower tube..

    Then ran into this.. which is a pretty awesome idea.. not what I want.. but future idea.

      I don't know about you, but I have no problems with setting my newborn's car seat right across the top of my legs. It actually rides there surprisingly stable. And if I needed to improve that I know I'd be able to strap it.

      Not trying to take away from what you're trying to accomplish though. I'll try and give this some thought this weekend.

        Cut the Tilite luggage carrier clamp longitudinally in half so that it can be placed anywhere.

        I have had periodic paralysis all my life. I lost my ability to walk in 2011 beginning with a spinal block, which was used for a hip fracture caused by periodic paralysis.

          hoping for a more modular solution, plus the tilite stuff isn't cheap.

                Looks like a winner to me. I might order one after checking diameters for my purpose. I wonder if they are mix and match. That is could you combine 1 inch on one end and say 7/8 inch on the other end?

                        I know for a fact that the Rotocon clamps from 1/2 to 5/8 to 3/4 to 7/8 to 1 inch will all fit together. Their measurements are for outside diameters of the attached tubing or rods. You will need a 5/16" hex key to loosen or tighten the clamps.

                          The Rotocon www.rotocon.com clamps in the large series (1/2, 5/8, 3/4, 7/8 and 1 inch sizes) will all fit with each other. You will need a 5/16" Allen or hex wrench to tighten and loosen. Good luck.

                              I went with Marine stainless steel pipe fittings. 1" for the Tilite tubing and 7/8" for the aluminum tubing.

                              with nothing attached I have four fittings on the chair, one pair are clamps and the front ball joint is screwed to my chair frame.


                              My attachment





                              marine chair attachment lets it rotate to 12 lockable positions.





                              allows the base to stay horizontal in the two positions I require.


                              up high for smaller footprint and maneuverability, but no visibility.



                              down low, for visibility..
