Abstract
A ball chair may comprise a chair frame, a ball body and an adjusting unit. The chair frame has a connecting base and a legs base, and a supporting column formed therebetween is configured to achieve a telescopic action thereby adjusting a height of the ball chair. The connecting base is formed in a concave shape to form a housing space therein, and an annular frame is formed at an upper end of the connecting base. The ball body is configured to be coupled on the connecting base of the chair frame, and the annular frame is configured to couple with an outer periphery of the ball body thereby limiting a position thereof. As a result, the ball chair is suitable for different statures of users and enables the users to sit thereon for training or rehabilitation.
Claims17
A ball chair comprising:
- a chair frame having a connecting base and a legs base, and a supporting column which is formed therebetween and configured to achieve a telescopic action;
- the connecting base formed in a concave shape to form a housing space therein, and an annular frame formed at an upper end of the connecting base;
- and
- a ball body configured to couple on the connecting base of the chair frame, and the annular frame configured to couple with an outer periphery of the ball body to limit a position thereof,
- wherein a first connecting slot is formed at a central bottom portion of the connecting base, the first connecting slot having an inner wall with longitudinal extents from a first end to a second end, and the first connecting slot is pivotally connected to an upper end of the supporting column;
- a metal ring is coupled with an the inner wall of the first connecting slot and entirely disposed between the first end and the second end of the first connecting slot, and at least an opening formed at a bottom portion of the connecting base adjacent to the first connecting slot is configured to enable an adjusting unit to install therein;
- and the supporting column has an abutting portion formed at the upper end thereof, and the adjusting unit is configured to press the abutting portion of the supporting column to achieve the telescopic action.
A ball chair comprising:
- a frame defining a concave space configured to accept a ball body, the frame comprising a connecting base, a central region of a bottom portion of the connecting base comprising a first connecting slot with an inner wall having longitudinal extents from a first end to a second end;
- a legs base;
- a telescopically adjustable supporting column disposed between the connecting base and the legs base to adjustably change a distance between the connecting base and the legs base, the supporting column comprising an abutting portion for adjusting a height of the supporting column, an upper end of the supporting column pivotally engaged with the first connecting slot;
- a metal ring coupled with the inner wall of the first connecting slot and entirely disposed between the first end and the second end of the first connecting slot, the supporting column pivotally passing through the metal ring;
- and
- an adjusting unit coupled to the connecting base and configured to engage the abutting portion of the supporting column to selectively telescopically adjust the height of the supporting column.
