Bathing seat structure for use in a bathtub
View Patent ↗The present invention provides a bathing seat structure for use in a bathtub, wherein the legs frame enables fixed positioning of the base, and the base enables fixed positioning of the seat cushion. The base is provided with two freeing mechanisms, a lever, and a rolling device. After pulling open the lever, the rolling device enables the seat cushion to rotate. The two freeing mechanisms must be pressed to a predetermined depth and must be pressed simultaneously, only then can the seat cushion be shifted laterally, thus preventing inadvertent contact and causing displacement of the seat cushion. The rolling device uses a two-tier centrifugal configuration, thereby supporting equal distribution of a person's weight to achieve smooth rotation with no inclining of the seat cushion, and thus extending the serviceable life of the rolling device.
1. A bathing seat structure for use in a bathtub, comprising:
a legs frame, which is assembled from a plurality of bars and placed within a bathtub or disposed to traverse a bathtub, the legs frame is fitted with two top cross bars, which are provided with a plurality of positioning holes, spring members and positioning plugs are disposed within each of the top cross bars, wherein the positioning plugs protrude external of the positioning holes;
a base, which comprises an upper plate and a lower plate, the lower plate is pin connected to the legs frame, and a bottom portion of the lower plate is provided with a plurality of pin connecting tubes that are mounted on an exterior of the top cross bars, wherein two front-end pin connecting tubes are respectively configured with a freeing mechanism; the upper plate is joined to a seat cushion, and a rolling device is fitted between the upper plate and the lower plate, the upper plate is provided with an upper through hole, and the lower plate is provided with a lower through hole; the upper plate is fitted with a lever, which is provided with a spring and a clasp post, wherein the clasp post inserts into the upper through hole and the lower through hole;
the seat cushion, which is joined to an upper plate of the base, and a bottom portion of the seat cushion is fixedly positioned with a bolt that enables mounting a spring thereon;
each of the freeing mechanisms comprises a press button, a spring, and a stud bolt, wherein the press button is provided with a press column, the spring is mounted on the press column, and the stud bolt combines internally with the press column; each of the pin connecting tubes is externally configured with a protruding body, which is internally provided with a through hole, and the through hole is internally provided with an inner push edge and an outer push edge;
the stud bolt is provided with a bolt head, the inner push edge stops the bolt head of the stud bolt when externally pushed thereon, and the outer push edge enables fixed positioning of a plug cap, which is internally provided with an inner push ring and an internal through hole, wherein the spring butts atop the inner push ring and the internal through hole enables the stud bolt to pass therethrough; pressing down on the press button connectively drives the stud bolt and the bolt head, whereupon the bolt head pushes atop and causes the positioning plug to retract from within the positioning hole, which is thus subjected to the natural restoring force of the spring;
the rolling device comprises a plurality of upper rollers, a circular plate, and a plurality of lower rollers, wherein the bottom surface of the upper plate is provided with a plurality of bottom positioning slots, and the upper rollers are disposed in the bottom positioning slots; the top surface of the lower plate is provided with a plurality of top positioning slots, and the lower rollers are disposed in the top positioning slots;
the circular plate is centrally pivot connected between the upper plate and the lower plate, and pulling the lever causes the clasp post to separate from the upper through hole; the base is internally provided with a two-tier configuration of the upper rollers and the lower rollers, wherein the upper rollers and the lower rollers are spread around the centre of the circular plate, thereby enabling smooth rotation on the lower plate of the base.
2. The bathing seat structure for use in a bathtub according to claim 1 , wherein each of the top cross bars are provided with two stop external rings, and displacement of the pin connecting tubes of the lower plate is stopped by the stop external rings.
3. The bathing seat structure for use in a bathtub according to claim 1 , wherein the lower portions on two sides of the seat cushion are each fitted with an armrest bar.
4. The bathing seat structure for use in a bathtub according to claim 1 , wherein the lower portion on one side of the seat cushion is fitted with the single armrest bar.
5. The bathing seat structure for use in a bathtub according to claim 1 , wherein the bathing seat is fitted with a pair of legs on each side of the legs frame.
6. The bathing seat structure for use in a bathtub according to claim 1 , wherein the lower portion on one side of the seat cushion is fitted with the single armrest bar, the bathing seat is fitted with only a pair of legs on one side of the legs frame and a clamping device is fitted on the other side.
