Releasable wheel mount system for a rollator

Releasable wheel mount system for a rollator comprising:

• a wheel axel fastened to a frame of a rollator comprising a groove near an outer end of the wheel axel and a circular sloped gliding surface at the outer end,
• characterized by a release trigger comprising:
• a locking shape with a locking surface for engaging the groove of the wheel axel in a locked state, thus locking the release trigger and wheel axel to each other, and
• a releasing shape that is a circular hole bigger than the axel for releasing the release trigger from the wheel axel in a releasing state, and
• wherein the locking shape is a semi-circular indent at the lower end of the releasing shape, wherein the semi-circular indent has a radius bigger than the radius of a circular circumferential groove of the axel,
• wherein the wheel mount system further comprises a housing comprising:
• a central cylinder with a cavity accommodating the wheel axel with a clearance,
• an outer rim stopper,
• an inner rim stopper, and
• a trigger cavity accommodating the release trigger, locking the release trigger and housing to each other, and
• wherein the release trigger is biased towards the locked state by use of biasing means and is operable to be pushed or pulled into the releasing state by a user.
