Abstract
A device for treating or preventing lower back pain that is simpler and less costly than previous similar devices. Among the features of the device are a leg rest height adjustment arrangement that is simple to operate and provides substantially continuous height adjustment, a leg rest folding mechanism that pivotally couples the leg rest to a leg rest support shaft to place the leg rest in operative and storage positions, and a flexible cover that does not substantially change its length during height adjustment.
Claims20
A device for treating or preventing lower back pain comprising:
- a leg rest;
- a single shaft that supports the leg rest;
- and
- a leg rest folding mechanism that pivotally couples the leg rest to the support shaft to move the leg rest from an operational position substantially perpendicular to the support shaft to a storage position lying along the support shaft;
- wherein the leg rest folding mechanism includes a pin mechanism and a guide track which cooperate to permit the leg rest to slide and pivot relative the leg rest support shaft.
A device for treating or preventing lower back pain comprising:
- a leg rest;
- a leg rest support assembly including a leg rest support shaft coupled to the leg rest;
- a drive unit including a drive shaft coupled to the leg rest support assembly for imparting cyclic motion to the leg rest that emulates the motion performed by a physiotherapist;
- a bellows forming a flexible cover for an upper end of a housing that contains the drive unit;
- and
- a leg rest height adjustment mechanism that cooperates with the leg rest support assembly to raise and lower the leg rest relative to the drive unit,
- wherein the length of the bellows is substantially unchanged during height adjustment and is only long enough to accommodate the cyclic motion of the drive shaft.
