Detailed Description

Before the present invention is described in detail, it should be noted that in the following description, like elements are represented by like reference numerals.

Referring to fig. 1 to 4, the first embodiment of the positionable swivel chair 100 of the present invention comprises a ball bearing 1, a lower support frame 2, an upper support frame 3, a chair seat 4 and a positioning mechanism 5.

The ball bearing 1 includes a fixed ring 11 and a rotating ring 12 capable of rotating relative to the fixed ring 11, the fixed ring 11 has a ring body 111 and a plurality of positioning holes 112 distributed at intervals on the ring body 111. In the embodiment, the fixed ring 11 and the rotating ring 12 are arranged in parallel in a concentric circle, and the fixed ring 11 surrounds the periphery of the rotating ring 12. The lower support frame 2 is connected below the fixing ring 11. The upper support frame 3 is connected above the rotating ring 12 to be linked with the rotating ring 12. The seat 4 is connected above the upper support 3 to be linked with the upper support 3.

In this embodiment, the lower support frame 2 includes a lower frame body 21 connected to the fixing ring 11, and four leg rods 22 respectively connected to the lower frame body 21 to jointly stand on the ground. The lower main frame 21 has two bottom rods 211 connected to the fixing ring 11 in a crossing manner, each bottom rod 211 has a transverse section 211a and two connecting sections 211b bent and extending downward from two ends of the transverse section 211a, and the leg rods 22 are connected to the connecting sections 211b of the bottom rods 211. Each leg 22 has a fixed section 221 and an adjustable section 222 capable of adjusting the distance relative to the fixed section 221, so that the length of the leg 22 can be adjusted telescopically.

In the present embodiment, the upper support frame 3 includes an upper main frame 31, a backrest 32 connected to the upper main frame 31, and two armrests 33. The upper main frame 31 has two push rods 311 parallel to each other and connected to the rotating ring 12 at intervals, and two carrier rods 312 connected to the push rods 311 at intervals and connected to the seat 4. The chair back 32 has two rear support rods 321 respectively connected to the top rods 311 and extending upward in a curved manner, and a backrest 322 connected to the rear support rods 321. The backrest 322 has a top side 322a, a bottom side 322b located below the top side 322a, and two side edges 322c respectively connecting the top side 322a and the bottom side 322b, and the length of the bottom side 322b is greater than that of the top side 322a, so that the appearance of the backrest 322 is an isosceles trapezoid with a narrow top and a wide bottom, and four corners are arc angles, thereby reducing the contact area between the back of the rider and the backrest 322, i.e. exposing more area of the back of the rider to facilitate the washing of the caregiver. The armrests 33 are respectively connected to two ends of the carrying rod 312 and located at two sides of the seat 4, each armrest 33 has two side supporting rods 331 respectively connected to the corresponding carrying rod 312 and extending upwards in a bending manner, and a hand supporting rod 332 connected to the side supporting rods 331.

Referring to fig. 3 to 5, the positioning mechanism 5 is connected to the upper supporting frame 3, and includes a latch 51 and a trip member 52 for driving the latch 51 to move in the up-and-down direction, so that the latch 51 can be movably inserted into one of the positioning holes 112, and the upper supporting frame 3, the seat 4 and the rotating ring 12 are positioned relative to the fixing ring 11. In this embodiment, the positioning mechanism 5 further includes a frame 53 connected to the upper supporting frame 3 and a return elastic member 54, the frame 53 has a bottom wall 531 adjacent to the fixing ring 11, the bottom wall 531 is provided with a through hole 532 for the pin 51 to pass through, the toggle member 52 has an arm 521 connected to the pin 51 and abutting against the bottom wall 531, and an operating portion 522 connected to the arm 521 and extending out of the frame 53, the return elastic member 54 is disposed between the frame 53 and the arm 521 to provide an elastic restoring force for the arm 521 to constantly abut against the bottom wall 531. The positioning mechanism 5 is engaged with the positioning hole 112 of the fixing ring 11, so that the seat 4 can rotate and can be positioned at different rotation positions, so that the caregiver can rotate the seat 4 to rotate the body of the rider, thereby cleaning different parts of the body of the rider. Moreover, since the positioning mechanism 5 is connected to the upper supporting frame 3, when the caregiver operates the pulling member 52, the pulling member 52 is pulled from bottom to top to move the pin 51 upward to separate from the positioning hole 112, and when the upper supporting frame 3 rotates to a proper position, the pulling member 52 is released to allow the pin 51 to penetrate into another positioning hole 112, so that the upper supporting frame 3 is positioned. By pulling the pulling member 52 in the vertical direction, the caregiver can easily operate the device, and the device can be operated smoothly.

Referring to fig. 6 to 9, the difference between the second embodiment of the positionable swivel chair 100 of the present invention and the first embodiment is: the lower support frame 2 includes a lower frame body 21 connected to the fixing ring 11, and two side frame bodies 23 symmetrically connected to opposite sides of the lower frame body 21 and adjustable in distance to straddle the tops of opposite sidewalls of a bathtub (not shown). The lower main frame 21 has two bottom rods 211 parallel to each other and connected to the fixing ring 11 at intervals, and two cross-over bars 212 parallel to each other and connected to two ends of the bottom rods 211 at intervals. Each side frame 23 has a support section 231 for supporting against the bathtub, and two connecting sections 232 extending from two ends of the support section 231 and respectively connecting the cross-over cross bar 212 in an adjustable length. The length can be adjusted by the connecting rod section 232 of the side frame body 23, and the distance between the abutting rod sections 231 of the side frame body 23 can be adjusted to adapt to the distance of the two opposite side walls of the bathtub to be set.
