This thesis is about folding an ergonomic stall fork shaft in the middle. Reason for the folding of the shaft is partly a customer wish but the main reason is the high cost of shipping. The cost of shipping will be relatively low if the package size is kept below the size of which the shipping company recommends. If you want to transport a package that is larger than the recommend size, the shipping cost well rise drastically.In this case, the cost of a package with size of one meter is deemed to be a profitable shipping cost. The problem is that the total length of the entire stall fork is 1.5 meters, which increases the shipping cost by about 100 SEK per package. Therefore, the stall fork must be folded in the middle to become cheaper to ship.The task is to get on a good and inexpensive solution to a clutch mechanism that allows customers to very easily and simply connect the two shafts together. Because of the shaft being ergonomic, it reduces physical abrasion damages and therefore is the main selling argument. That’s why it is very important not to bring any changes to the ergonomic design or, in worst case, as little as possible.The result was a coupling out of a polymer material that divides the shaft approximately from the middle, has a low weight and is easy for the consumer to assemble the two parts of the shaft. The work was carried out by studies of different couplings to be able to come up with a number of different proposals for splitting of the shaft. Furthermore were different materials closely examined and manufacturing methods that the coupling can be manufactured by.The result was a prototype of coupling out of a polymeric material that divides the shaft approximately in the middle, has a low weight and is easy for the consumer to assemble the two shaft halves. The coupling consists of parts, male, female and a core in the middle to make the link robust.
