a helping handle

This solution was designed for quickie wheelchairs. These wheelchairs have a mechanism to rotate the armrest backwards and exit the wheelchair sideways but such mechanism can only be used with two hands. Upon assembling the product, it can be attached to the wheelchair and allows for one-handed usage of the mechanism. To do so, it locks the default system's handle in place once the handle is pressed and releases it again once a hook is pulled. This solution allows easier exit of this type of wheelchairs for one-handed users and can be adapted to other use cases.

The instructions section contains a description of how to recreate the solution's parts.
