Abstract
There is provided a wheel mounting assembly having a wheel fork. The fork includes an interior and an inwardly extending protrusion disposed within the interior. The assembly includes a rotatable member operatively connected to the fork and disposed within the interior of the fork. The protrusion abuts and positions in place the rotatable member. The assembly includes a shaft. The rotatable member rotatably connects the shaft to the wheel fork. The assembly includes a retaining member connected to the shaft. The retaining member is configured to abut the protrusion of the fork and thus inhibit dislodgement of the rotatable member from the fork when the shaft is tilted relative to the fork.
Claims17
A wheel mounting assembly comprising:
- a wheel fork having an interior and an inwardly extending protrusion disposed within the interior;
- a rotatable member operatively connected to the fork and disposed within the interior of the fork, the protrusion abutting and positioning in place the rotatable member;
- a shaft, the rotatable member rotatably connecting the shaft to the wheel fork;
- and
- a retaining member connected to the shaft, the retaining member being configured to abut the protrusion of the fork and thus inhibit dislodgement of the rotatable member from the fork when the shaft is tilted relative to the fork.
In combination, the wheel mounting assembly as claimed in 1 together with a walker apparatus therefor.
A wheel mounting assembly comprising:
- a pivotable wheel fork rotatably connectable with a ground-engaging wheel, the fork having an interior;
- a frame portion having an interior, a first one of the fork and the frame portion having an inwardly extending protrusion disposed within its interior;
- a shaft coupled to a second one of the fork and the frame portion;
- a rotatable member operatively connected to the first one of the fork and the frame portion and disposed within the interior of the first one of the fork and the frame portion, the protrusion abutting and positioning in place the rotatable member, the rotatable member rotatably connects the shaft to the first one of the fork and the frame portion;
- and
- a retaining member connected to the shaft, the retaining member being configured to abut the protrusion and thus inhibit dislodgement of the rotatable member from the first one of the fork and the frame portion when the shaft is tilted relative to the first one of the fork and the frame portion.
