What you need to make the tricycle ?

If bicycle wheels are unavailable or too expensive, you can manufacture them yourself (refer to «Making AWheel For A Wheelchair», Handicap International edition, 1st Quarter 1994).You can also make a pipe-bending machine (refer to «How To Make A Pipe-Bending Machine», byM. Walsby - IT edition) Intermediate Technologies Publications Ltd.

9 King Street, London WC2E8HW, U.K.

The tricycle model presented here has been manufactured for the last 10 years, using materials andaccessories available locally.Whenever possible, we will show you other existing solutions.You will then be able to adapt manufacture ofthe tricycle to materials you have available...Don’t hesitate to develop more adapted systems and above all, please send us details!

Remark :Jigs are used for cutting the iron sheets (foot-rest, sides) andan assembly jig exists for all parts of the rear wheel support.The mounting of the whole frame is done without a jig. Alltypes of welding are used ; electric, gas and brazing welder.


Preliminary remarks :

All measurements given are in millimeters (mechanic & metallic construction standard) and mustbe considered as such when not stipulated otherwise in the text.

A tube specified as «light» has a maximum thickness of 1mm.A tube specified as «heavy» has a thickness of more than 1mm (often 1,5 or 2,0mm).

The parts are numbered and correspond with numbers shown in diagrams in the appendix. Theyare numbered as parts of a subset.Relative to the original plans, some parts have been modified or not used, and numbers aretherefore not necessarily consecutive.

For greater strength in the assembly of parts, tubes must be correctly adjusted to each other, thusalso making welding easier.

➡ Flatten both ends of the backrest tube (N°141) on the inside, and fit them either side of the rearcorner iron. The lower ends are then at the lowest point of the angle of the lateral corner ironN°143. Fix the backrest, its final position being determined by placing the arm-rest 210mm fromthe base of the backrest and in the two angles to the front of the seat base. The metal grid forcushion support is then placed in the backrest as follows. Fix two 440mm long flat irons (N°147)vertically, 120mm from the backrest base. Fix N°145 horizontally, 140mm from the upper edge ofthe rear corner iron and N°146, 280 mm from the upper edge of the rear corner iron. (see fig. 5)

N°181: The axleIron rod diam. 16mm, length: 170mm

N°186: The hub of the bicycle wheelSubdivided into:186a, the hub186b, the axle186c, the locknutGrind down a 60mm portion of the axle’sthreaded part. Weld this smooth end in theaxis of the axle rod. Mount the hub on theaxle, tighten with a locknut, and weld all inplace.

figure n°13


7. The fork


A commercial bicycle fork is used here and modified to correspond to our needs. Modifications involve thelength of the fork arms, the diameter of the wheel fixation, the length of the fork axis, and lastly, theaddition of the two parts (N°191) which will hold the steering transmission rods.

Modification of the fork arms:Heat and disconnect the two fork arms and cut 100mm off their length. While the fork arms are free, grinddown the wheel fixing points to allow for use of a bigger wheel axle (rear wheel hub).

Shortening axle length:As the handlebar pillar length required is shorter than that of a normal bicycle model, reduce the threadedpart of the axle by 30mm, leaving a length of only 160mm.

N°192: Parts holding steering transmission rods Heavy duty corner iron 25 x 25mm, length:40mmCut: 2 pcs.x 20mm. Drill: 6mm diam. hole in the center of onewing of each part, Reduce the other wing by10mm.


ASSEMBLY

➡ Weld the two parts (N°192) to the fork, 15mm from the edge, with wings directed outwards, theright angle facing down.

8. The body work


SUBSET 200:The body work Parts used N°201.202

N°201: The floor/footrestIron sheet 10/10mm (1mm), dimensions:900 x 500mmShape: tracing the outline for the floor onthe iron sheet can be easily done using a jigof exactly the same dimension cut out of athicker iron sheet.

Once the tracing is done (see diagram), cutusing chassis shears for the general form,heavy duty shears for notches, and a chiselfor the central oblong hole. Then drill 14holes of 4mm diameter, 150mm apart, in theiron sheet.These holes are for fixation, using3 x 10mm aluminum rivets. (see fig. 15)

figure n°15


N°202: The sides of the arm-rests Iron sheet 10/10mm, dimensions: 500 x500mmCut: 2 pcs x (250 x 500mm)In the same manner, trace the side of thearm-rest on the iron sheet using a jig and cutwith chassis shears. Use heavy duty shearsto modify the side of one arm-rest (left orright, depending on the user’s preference)for the brake fixation.

Drill 8 holes of 4mm diameter in the sides tofix them on the arm-rest, using 3 x 10 mmaluminum rivets. Being symmetrical, bothsides are made in the same way.(see fig. 16)

figure n°16


9. The jig


THE JIG FOR THE REAR WHEEL SUPPORT.

This jig is made with light angle iron 25 X 25.

Cutting necessary to have access for welding.


VARIATIONS

Elements mentioned as being purchased in commerce in the preceeding pages may notalways be available (or their price be too high). We have therefore attempted here todevelop replacement solutions. For this wheelchair model developed in Bobo-Dioulasso, it is possible to replace the forkand brake system. The following alternatives come from similar models, built at Dosso(Niger).


ASSEMBLY

➡ Weld the fork axle perpendicular to the center of part N°403. Weld the two fork arms N°402 undereither end of the connection plate. Finally, reinforce the fork arms and connection plate with thetwo reinforcement parts N°404.
