[0052] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0053] Reference Figures 1 to 9 As shown, this utility model provides a multifunctional commode chair.

[0054] The multi-functional commode chair includes a seat 100 and two support units 200.

[0055] Reference Figure 1 and Figure 2 As shown, the structures of the two support units 200 are mirror images of each other, and the two support units 200 are respectively located on the left and right sides of the bottom of the seat 100.

[0056] Each support unit 200 includes a base frame 210, a slider 220, a first locking member 230, a first support member 240, a second support member 250, a drive member 260, and two casters 270.

[0057] The base frame 210 extends in the front-to-back direction, and casters 270 are installed on the front and rear sides of the base frame 210 respectively. The casters 270 are swivel wheels with locking function.

[0058] The sliding member 220 is slidably mounted on the outside of the base frame 210. The sliding member 220 can slide in the front and back direction. The bottom of the sliding member 220 is provided with a through locking screw hole, which is directly opposite the bottom wall of the base frame 210. The first locking member 230 is a screw with a knob. After the screw is screwed into the locking screw hole, it abuts against the bottom wall of the base frame 210. By tightening the first locking member 230, the end of the screw presses against the bottom wall of the base frame 210, thereby preventing the sliding member 220 from sliding back and forth relative to the base frame 210.

[0059] The first support member 240 includes an inner rod 241, an outer cylinder 242, and a positioning part. The outer cylinder 242 is fitted outside the inner rod 241. The bottom of the inner rod 241 extends outside the outer cylinder 242. The bottom of the inner rod 241 is hinged to the base frame 210, and the hinge position between the inner rod 241 and the base frame 210 is located behind the sliding member 220. The side wall of the inner rod 241 is provided with a pin hole 2411. The top of the outer cylinder 242 is hinged to the bottom of the seat 100. The side wall of the outer cylinder 242 is provided with a plurality of through positioning holes 2421. The plurality of positioning holes 2421 are spaced apart along the sliding direction of the inner rod 241 relative to the outer cylinder 242, and the plurality of positioning holes 2421 are located on the sliding trajectory of the pin hole 2411. The positioning part is a pin. After the positioning part passes through the positioning hole 2421, it is inserted into the pin hole 2411 to fix the position of the outer cylinder 242 relative to the inner rod 241.

[0060] The outer cylinder 242 is also provided with a through clearance groove 2422 on its side wall. The clearance groove 2422 extends along the sliding direction of the outer cylinder 242 relative to the inner rod 241.

[0061] The bottom end of the second support member 250 is hinged to the sliding member 220, and the top end of the second support member 250 is hinged to the inner rod 241. The hinge structure between the top end of the second support member 250 and the inner rod 241 is located in the clearance groove 2422. When the positioning part is disassembled and the outer cylinder 242 slides relative to the inner rod 241, the hinge structure between the top end of the second support member 250 and the inner rod 241 slides in the clearance groove 2422. The length of the clearance groove 2422 in the sliding direction of the outer cylinder 242 relative to the inner rod 241 is greater than the distance between the two farthest positioning holes 2421, so as to avoid the clearance groove 2422 interfering with the hinge structure between the top end of the second support member 250 and the inner rod 241.

[0062] When the first locking member 230 is released, the sliding member 220 can slide back and forth relative to the base frame 210, thereby causing the sliding member 220 to drive the bottom end of the second support member 250 to slide back and forth. The second support member 250 drives the first support member 240 to rotate relative to the base frame 210 and the seat 100, thereby changing the distance between the seat 100 and the base frame 210 and adjusting the height of the seat 100.

[0063] Reference Figures 1 to 3 As shown, the drive component 260 is a controllable pneumatic spring or a controllable hydraulic spring. The drive component 260 includes a connected mounting part 261 and a movable part 262. The drive component 260 drives the movable part 262 to move and extend in a straight line relative to the mounting part 261 and fixes the position of the movable part 262 during extension and retraction.

[0064] The top end of the mounting part 261 is hinged to the bottom of the seat 100, and the hinge structure between the mounting part 261 and the bottom of the seat 100 is located behind the hinge structure between the first support member 240 and the bottom of the seat 100. The movable part 262 is slidably disposed at the bottom end of the mounting part 261, and the bottom end of the movable part 262 is hinged to the first support member 240. By extending and retracting the movable part 262 through the drive member 260, the rear side of the seat 100 is moved closer to or further away from the rear side of the base frame 210, thereby adjusting the angle of the seat 100 relative to the horizontal plane.

[0065] By changing the height and angle of the seat 100 relative to the base frame 210 through two support units 200, the commode chair can be adjusted to a comfortable posture according to the user's needs, allowing the user to sit in a reclining position to assist in bathing, making the commode chair more convenient to use.

[0066] Reference Figure 1 and Figure 3 As shown, the seat 100 includes a seat 110, a backrest 120, a first adjustment member 130, a rotation adjustment member 140, a footrest 150, an armrest 160, a side rail 180, and a second locking member 190.

[0067] The seat 110 has a through hole 111 in the middle of the seat 110, which runs vertically. Two support units 200 are connected to the left and right sides of the bottom of the seat 110 respectively. By changing the height and angle of the seat 110 relative to the base frame 210 through the two support units 200, the commode chair can be adjusted to a comfortable posture according to the user's needs, allowing the user to sit on the seat in a reclining posture to assist in bathing, making the use of the commode chair more convenient.

[0068] The backrest 120 includes two hinges 121 and a back panel 122.

[0069] Reference Figure 3 and Figure 4 As shown, two hinge parts 121 are respectively hinged to the left and right ends of the rear side of the seat plate 110. The two hinge parts 121 can rotate around an axis extending in the left and right direction. Each hinge part 121 has a plug hole at its top. The bottom left and right ends of the back plate 122 are respectively provided with downwardly extending plug rods 1221. The two plug rods 1221 are respectively inserted into the two plug holes. Each plug hole has a through fixing screw hole on its side wall. After the fixing screw is screwed into the fixing screw hole, it extends into the plug hole and abuts against the plug rod 1221, thereby fixing the plug rod 1221.

[0070] Reference Figure 3 and Figure 4 As shown, the two first adjustment members 130 are respectively installed at the left and right ends of the rear side of the seat plate 110, and the two first adjustment members 130 are respectively located on the side of the two hinge parts 121.

[0071] Reference Figure 4 As shown, the first adjusting member 130 includes a first connecting part 131 and a first limiting part 132. The first connecting part 131 is connected to the left or right end of the rear side of the seat plate 110. The first connecting part 131 is provided with a plurality of through first connecting holes 1311, which are distributed at intervals in the vertical direction. The first limiting part 132 is detachably installed in any one of the first connecting holes 1311 and extends behind the hinge part 121. The first limiting part 132 restricts the stroke of the hinge part 121 to rotate backward, thereby limiting the angle of the backrest 120 to rotate backward. The user can install the first limiting part 132 into any one of the first connecting holes 1311 as needed, thereby changing the angle of the backrest 120 to rotate backward, and thus adjusting the angle between the backrest 120 and the seat plate 110 to adapt to different reclining angles of the user.

[0072] Reference Figure 3 and Figure 5 As shown, the backrest 120 also includes an up-and-down adjustment part 123, a left-and-right adjustment part 124, and two screws 125.

[0073] The up-down adjustment part 123 is installed on the rear side wall of the back plate 122. The up-down adjustment part 123 is provided with multiple screw holes 1231, which are divided into two rows along the left-right direction. The multiple screw holes 1231 in the same row are spaced apart along the up-down direction. The left-right adjustment part 124 is provided with an adjustment groove 1241 that runs through the front and back. The adjustment groove 1241 extends along the left-right direction and its length in the left-right direction is greater than the distance between the two rows of screw holes 1231. Two screws 125 are spaced apart in the adjustment groove 1241. After the two screws pass through the adjustment groove 1241, they are screwed into two adjacent screw holes 1231, so that the left-right adjustment part 124 is installed on the up-down adjustment part 123. Loosening the two screws 125 allows the left-right adjustment part 124 to change its position in the left-right direction. By aligning the adjustment groove 1241 with two different screw holes 1231, the position of the left-right adjustment part 124 in the up-down direction can be changed.

[0074] The hinge 170 connects to the left and right adjustment part 124. The hinge 170 is provided with a hinge shaft 171 extending in the vertical direction. The side stop 180 includes a side stop part 181, a connecting rod 182, and a locking seat 183. The locking seat 183 is provided with a hinge hole that extends vertically. The hinge hole cooperates with the hinge shaft 171 to allow the locking seat 183 to rotate around a vertical axis. The hinge 170 is also provided with a first directional hole that extends vertically, and the locking seat 183 is also provided with a second directional hole that extends vertically. The first directional hole is located on the rotation trajectory of the second directional hole. The second locking member 190 passes through the first directional hole and is inserted into the second directional hole to fix the locking seat 183.

[0075] The locking seat 183 has a locking hole that runs through the front and back direction. The side wall of the locking hole has a through locking groove. The two side walls of the locking groove can move closer or further apart to compress or open the locking hole. One side wall of the locking groove has a threaded hole and the other side wall has a through hole. The through hole and the threaded hole are directly opposite each other. The locking screw is screwed into the threaded hole through the through hole. Tightening the locking screw brings the two side walls of the locking groove closer together, and loosening the locking screw allows the two side walls of the locking groove to move further apart.

[0076] The connecting rod 182 includes a crossbar extending in the front-back direction and a vertical bar perpendicular to the crossbar. The crossbar is inserted into a locking hole. Tightening the locking screw brings the two sidewalls of the locking groove closer together, fixing the crossbar in the locking hole. Loosening the locking screw allows the two sidewalls of the locking groove to move away from each other, allowing the crossbar to rotate in the locking hole or be pulled out to disengage from the locking hole.

[0077] The vertical bar connects the horizontal bar and the side stop 181. By rotating the horizontal bar, the vertical bar causes the side stop 181 to rotate around an axis extending in the front-back direction.

[0078] Reference Figure 1 and Figure 3 As shown, two armrest components 160 are respectively installed on the left and right sides of the seat 110. Each armrest component 160 includes an armrest part 161 and a baffle part 162. The armrest part 161 is connected to the left or right side of the seat 110 through a bracket. There is a space between the armrest part 161 and the seat 110. The baffle part 162 is connected to the bracket and is arranged vertically between the armrest part 161 and the seat 110.

[0079] Therefore, the left and right sides of the seat 110 are respectively provided with a baffle 162, an armrest 161 and a side guard 181. When the user of the commode chair is a child, the baffle 162, armrest 161 and side guard 181 arranged from bottom to top can prevent the child from falling from the left and right sides of the seat 110, which helps the child use the commode chair safely to assist with excretion or bathing.

[0080] Furthermore, the side guard 180 can adjust the position of the side guard 181 in the vertical direction and the left and right direction, which helps to accommodate children of different body types.

[0081] Reference Figure 9As shown, the foot pedal 150 includes a pedal 151, two assembly parts 152, and two second adjusting parts 153. Limiting holes 1511 are respectively provided on the left and right sides of the pedal 151. Each second adjusting part 153 includes a second connecting part 1531 and a second limiting part. The front sides of the two second connecting parts 1531 are hinged to the left and right ends of the pedal 151, allowing the pedal 151 to rotate relative to the second adjusting parts 153 about an axis extending in the left-right direction. The middle parts of the two second connecting parts 1531 are respectively connected to the two assembly parts 152. Each second connecting part 1531 has multiple second connecting holes 1532 spaced vertically at the rear of the assembly part 152. The multiple second connecting holes 1532 are located on the rotation trajectory of the limiting holes 1511. The second limiting part passes through any one of the second connecting holes 1532 and inserts into the limiting hole 1511, thus fixing the position of the pedal 151 relative to the second adjusting parts 153, that is, fixing the position of the pedal 151 relative to the two assembly parts 152.

[0082] Therefore, after adjusting the angle of the pedal 151 by disassembling the second limiting part, the limiting hole 1511 is aligned with the second connecting hole 1532. Then, the second limiting part is inserted into the limiting hole 1511 after passing through the second connecting hole 1532 to complete the angle adjustment of the pedal 151, so as to adapt to different sitting postures of the user.

[0083] Each assembly part 152 includes an inner tube and an outer tube. The inner tube is slidably fitted into the outer tube. The side wall of the outer tube is provided with multiple adjustment holes spaced vertically. The inner tube is provided with an elastic buckle. The elastic buckle tends to extend outward under the action of elastic force. The multiple adjustment holes are located on the trajectory of the elastic buckle as the inner tube slides up and down. When the elastic buckle is aligned with any adjustment hole, the elastic buckle is inserted into the adjustment hole and extends out of the outer tube, fixing the relative position of the inner tube and the outer tube. Therefore, the position of the inner tube relative to the outer tube can be adjusted by pressing the elastic buckle.

[0084] The outer tube is connected to the second adjusting member 153, and the inner tube is used to connect to the rotating adjusting member 140.

[0085] Reference Figures 6 to 8 As shown, the rotation adjustment member 140 includes:

[0086] The first rotating part 141 is connected to the front side of the seat plate 110, and the first rotating part 141 is provided with a first internal gear ring 1411;

[0087] The second rotating part 142 is connected to the assembly part 152. The second rotating part 142 is rotatably connected to the first rotating part 141. The second rotating part 142 is provided with a second internal gear ring 1421. The second internal gear ring 1421 is arranged opposite to the first internal gear ring 1411. The axis of the first internal gear ring 1411, the axis of the second internal gear ring 1421, and the rotation axis of the second rotating part 142 are coaxially arranged.

[0088] An anti-rotation part 143 is slidably disposed between the first internal gear ring 1411 and the second internal gear ring 1421. The anti-rotation part 143 is provided with an external gear ring 1431, which cooperates with the first internal gear ring 1411 and the second internal gear ring 1421.

[0089] When the anti-rotation part 143 is located in the first internal gear ring 1411, the second rotating part 142 rotates relative to the first rotating part 141.

[0090] When the anti-rotation part 143 is located between the first internal gear ring 1411 and the second internal gear ring 1421, the outer gear ring 1431 prevents the second rotating part 142 from rotating relative to the first rotating part 141.

[0091] The rotation adjustment member 140 also includes an elastic part 144, a pressing part 145, and a sliding ring 146.

[0092] The elastic part 144 is disposed between the anti-rotation part 143 and the first rotating part 141. The elastic force of the elastic part 144 causes the anti-rotation part 143 to have a tendency to move towards the second internal gear ring 1421.

[0093] The pressing part 145 is slidably disposed on the second rotating part 142. The pressing part 145 extends into the second internal gear ring 1421 and abuts against the anti-rotation part 143. Pushing the pressing part 145 to move towards the anti-rotation part 143 causes the anti-rotation part 143 to resist the elastic force of the elastic part 144 and move downward into the first internal gear ring 1411, so that the second rotating part 142 can rotate relative to the first rotating part 141.

[0094] The first rotating part 141 is provided with a first annular groove 1412, and the second rotating part 142 is provided with a second annular groove 1422. The first annular groove 1412 and the second annular groove 1422 are directly opposite each other, and the sliding ring 146 is disposed between the first annular groove 1412 and the second annular groove 1422.

[0095] Therefore, pressing the pressing part 145 moves it toward the anti-rotation part 143, causing the anti-rotation part 143 to resist the elastic force of the elastic part 144 and move downward into the first inner gear ring 1411, allowing the second rotating part 142 to rotate relative to the first rotating part 141, thereby adjusting the angle of the foot pedal 150 relative to the seat 110; releasing the pressing part 145 causes the elastic part 144 to push the anti-rotation part 143 toward the second inner gear ring 1421, causing the outer gear ring 1431 of the anti-rotation part 143 to engage in the second inner gear ring 1421, preventing the second rotating part 142 from rotating relative to the first rotating part 141, thereby fixing the angle of the foot pedal 150 relative to the seat 110, so that the foot pedal 150 can adapt to different sitting postures of the user.

[0096] Reference Figure 1 and Figure 3 As shown, the multi-functional commode chair also includes a headrest 300, which is installed on the top of the backrest 120. The headrest 300 can be adjusted in position along the front-back direction and can also be adjusted in angle around an axis extending in the left-right direction to adapt to the user's sitting posture.

[0097] Reference Figure 1 As shown, the multi-functional commode chair also includes a crotch stop 400. A mounting groove is provided on the front side of the seat 110. The shape of the bottom of the crotch stop 400 matches the shape of the mounting groove. The bottom of the crotch stop 400 can be detachably inserted into the mounting groove. The crotch stop 400 extends upward above the seat 100 to restrict the user from the crotch and prevent the user from slipping off the front of the seat 110.
