Bathing chair with fixing clamp assembly
A bathing chair with a fixing clamp assembly comprises a front frame and a rear frame, having horizontal rods, a seat, several gliding blocks, a backrest, a handle, and a fixing clamp assembly. The fixing clamp assembly further comprises an upper plate, laid on an edge of a bathtub, an outer plate, attached to the upper plate and leaning against an outer side of a bathtub wall, a connecting tube, having an outer end, which is fastened to an upper side of the upper plate, a holding arm, shaped like the letter L and having a lateral end, which has an inner thread and is inserted into an inner end of the connecting tube, a holding plate, which is fastened to a lower end of the holding arm and leans against an inner side of the bathtub wall, and a threaded rod, passing through the connecting tube and engaging with the inner thread. By turning the threaded rod, the holding plate is fastened on the bathtub wall and released therefrom to be able to glide thereon.
The present invention relates to a bathing chair with a fixing clamp assembly, particularly to a bathing chair with a turnable seat for convenient siting down and a fixing clamp assembly.
BACKGROUND OF THE INVENTIONAs shown in
A conventional bathing chair as just described assists elderly and handicapped people to enter and leave a bathtub safely and conveniently. However, completely bridging the bathtub 1, the front and rear frames 21, 22 have large sizes and hence are inconvenient to transport.
SUMMARY OF THE INVENTIONIt is an object of the present invention to provide a bathing chair with a fixing clamp assembly which takes up a relatively small space.
It is another object of the invention to provide a bathing chair with a fixing clamp assembly which is easy to transport.
It is a further object of the invention to provide a bathing chair with a fixing clamp assembly which is easily and safely fastened to a bathtub.
For achieving above objects, the present invention comprises a front frame and a rear frame, having horizontal rods, a seat, several gliding blocks, a backrest, a handle, and a fixing clamp assembly. The fixing clamp assembly further comprises an upper plate, laid on an edge of a bathtub, an outer plate, attached to the upper plate and leaning against an outer side of a bathtub wall, a connecting tube, having an outer end, which is fastened to an upper side of the upper plate, a holding arm, shaped like the letter L and having a lateral end, which has an inner thread and is inserted into an inner end of the connecting tube, a holding plate, which is fastened to a lower end of the holding arm and leans against an inner side of the bathtub wall, and a threaded rod, passing through the connecting tube and engaging with the inner thread. By turning the threaded rod, the holding plate is fastened on the bathtub wall and released therefrom to be able to glide thereon.
Other aspects and advantages of the present invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, illustrating by way of example the principles of the present invention.
As shown in
The front and rear frames 21A, 22A are each shaped like the letter L, having outer ends that are fastened to the fixing clamp assembly 70, thereby being held on the bathtub wall 14 as needed.
For avoiding slipping aside of the front and rear frames 21A, 22A and protecting the bathtub wall 14, inner walls of the upper plate 71, the outer plate 72 and the holding plate 77 each are covered by a sticking cover 82.
A lid 74 is set on the outer end of the connecting rod 73 and is passed through by the threaded rod 80. The threaded rod 80 has an outer end which carries a handle 81 and an inner end which engages with the inner thread 76 of the holding arm 75. By manual turning of the threaded rod 80, the holding arm 77 is loosened, allowing to shift the front and rear frames 21A, 22A back and forth.
The connecting rod 73 and the holding arm 75 preferably have cross-sections in the shape of squares, for preventing turning thereof against the bathtub wall 14. Alternatively, the connecting rod 73 and the holding arm 75 have circular cross-sections, with grooves and blocking elements being provided (not shown).
To adapt to an inclination of the inner side 13 of the bathtub wall 14, the holding plate 77 carries two mounting plates 78, which are fastened to the lower end of the holding arm 75 by a bolt 79 at an adjustable inclination angle.
