This heavy duty ladder connects together via interlocking ball-joints.
By connecting the different sectional lengths of the ladder together with interlocking ball-joints and wing nuts, tightened using a power tool or transformed toothbrush you can now adjust the ladder to any length and angle.
With adjustable rubber feet and serrated rungs you can place the ladder at different angles of degree against a structure then ascending up or at a different angle to climb around or down.
Adjustable stabilisers can be jointed to compensate for sloping and uneven surfaces.-- skinflaps, Nov 05 2004 Flexible ladders http://www.ladders999.co.uk/ [etherman, Nov 05 2004] (?) Little giant http://www.thelittlegiantladderstore.com/Sorry not ball joints but ratchets. [2 fries shy of a happy meal, Nov 06 2004] I'm pretty sure this is very baked.-- contracts, Nov 05 2004 [contracts] I did a search and can't find it, unless I missed something.
If it's baked I'll gladly delete this.-- skinflaps, Nov 05 2004 Surely a ladder with so many joints could prove to be very weak, especially in longer length versions. Why use ball joints when you are only going to be able to flex it back wards and forwards? Angling the ladder to the right or left would make it unstable. Ladders which bend on one axis are baked.-- etherman, Nov 05 2004 You could sling it over the spine of your crooked house, for the purposes of making it easier to put crooked slates back on.-- calum, Nov 05 2004 Or climb over walls and traverse scaffolding.-- skinflaps, Nov 05 2004 I'm having trouble visualising this. Would there be a ball joint on each side in between the rungs? What is the difference between an interlocking ball joint and an ordinary one? How does this help you adjust the length of the ladder?-- st3f, Nov 05 2004 As mentioned, you have different lengths which lock together via two ball joints on each end of the sections.
Scenario: traverse a high wall with one long length, attach a different length, align and orientate the second length of ladder to the desired angle and lock it tight to where you wish to go.Three or four other different lengths may be required to ascend or descend via obsticles or terrain, to access your goal-- skinflaps, Nov 05 2004 Ah. Got it.-- st3f, Nov 05 2004 are the rungs hinged to the frame so that the ball joits can swivel left and right as well as back and forward?-- etherman, Nov 05 2004 The rungs are permanently fixed to each section of the different lengths of ladder, you could even attach three or four together to make a upright tower.-- skinflaps, Nov 05 2004 Oh ok, sorry for being so slow <freerunner>. It is Friday and all that. Was wondering if a quick release version of the ladders in the <link> might be more sturdy and easier to lock.-- etherman, Nov 05 2004 Very good. I have seen something like this on an info-mercial once. I'll see if I can find a link.-- 2 fries shy of a happy meal, Nov 06 2004 random, halfbakery
