Description

Technical Field

[0001] The utility model relates to the field of toilet chairs, and particularly to a liftable toilet chair. Background Art

[0002] Toilet chairs are important tools for the elderly with degenerated muscles and bones, weak limbs, and inconvenient squatting, or patients who are physically weak and have inconvenient mobility to use the toilet. Usually, a toilet hole is provided on the seat board of the toilet chair. In order to make the toilet chair more adaptable to users of different heights, some toilet chairs are provided with a lifting function so that the seat can be adjusted in height according to the needs of the user.

[0003] However, when a user uses a toilet chair to use the toilet, the feet are blocked by the toilet and cannot move backward, and the distance between the center of gravity of the body and the feet is relatively far. The user needs more strength to get up, resulting in difficulty in getting up. Content of the Utility Model

[0004] The purpose of the utility model is to provide a liftable toilet chair to solve one or more technical problems in the prior art, and at least provide a beneficial choice or create conditions.

[0011] A lifting mechanism, which is connected to the upper support member and the lower support member, and the lifting mechanism drives the upper support member and the lower support member to approach or move away from each other;

[0012] A seat, which is connected to the parallelogram mechanism.

[0013] The beneficial effects of the present utility model are as follows: When a user uses the toilet chair to relieve themselves, the lifting mechanism drives the upper support member away from the lower support member, causing the upper crossbar of the parallelogram mechanism to move away from the lower crossbar, so that the seat drives the user to move upward and backward to directly above the toilet; when the user finishes using the toilet, the lifting mechanism drives the upper support member closer to the lower support member, causing the upper crossbar of the parallelogram mechanism to move closer to the lower crossbar, so that the seat drives the user to move downward and forward to directly above the front of the toilet, leaving a space between the toilet and the user's feet, facilitating the user's feet to move backward while the user's body moves forward with the seat. Therefore, the center of gravity of the user's body is closer to the feet, reducing the force required for the user to stand up, and thus helping the user to stand up by themselves.

[0014] As a further improvement of the above technical solution, the seat is hinged to the parallelogram mechanism, and the liftable toilet chair further includes:

[0015] A drive mechanism, which is connected to the seat and the parallelogram mechanism, and the drive mechanism drives the seat to rotate around a horizontal axis.

[0016] As a further improvement of the above technical solution, the drive mechanism is a linear drive mechanism, and the drive mechanism is respectively hinged to the seat and the parallelogram mechanism.

[0017] As a further improvement of the above technical solution, the top end of the drive mechanism is hinged to the rear side of the seat, and the bottom end of the drive mechanism is hinged to the rear end of the lower crossbar.

[0018] As a further improvement of the above technical solution, the parallelogram mechanism is provided with a front vertical rod and a rear vertical rod that are parallel to each other front and back. The top of the rear vertical rod extends upward. The middle of the seat is hinged to the rear vertical rod, and the upper support member abuts against the front side of the seat.

[0019] As a further improvement of the above technical solution, the liftable toilet chair further includes:

[0020] An adjustment mechanism, which is connected to the top of the seat;

[0021] A headrest, which is connected to the adjustment mechanism, and the adjustment mechanism adjusts the up and down position and the front and back position of the headrest.

[0022] As a further improvement of the above technical solution, the adjustment mechanism includes:

[0023] A plurality of adjustment members, which are hinged to each other in sequence from head to tail. The adjustment member at the head end is connected to the top of the seat, and the adjustment member at the tail end is connected to the headrest;

[0024] A plurality of locking members, one locking member is arranged between every two hinged adjusting members, and locking the locking member fixes the relative positions of the two hinged adjusting members.

[0025] As a further improvement of the above technical solution, the lifting mechanism is a linear drive mechanism, and the lifting mechanism is respectively hinged to the upper support member and the lower support member.

[0036] Refer to Figure 1 As shown, the following embodiments are made for the lifting toilet seat of the present utility model:

[0037] The lifting toilet seat includes a bottom frame 100, a parallelogram mechanism 200, an upper support member 300, a lower support member 400, a lifting mechanism 500, and a seat 600.

[0038] The parallelogram mechanism 200 includes an upper cross bar 210 and a lower cross bar 220. The upper cross bar 210 is parallel to the lower cross bar 220. The lower cross bar 220 is connected to the bottom frame 100. The upper cross bar 210 moves parallel to the lower cross bar 220. In this embodiment, the upper cross bar 210 moves forward and downward parallel to the lower cross bar 220, and the upper cross bar 210 moves backward and upward parallel to the lower cross bar 220.

[0039] The upper support member 300 is connected to the upper cross bar 210, and the lower support member 400 is connected to the lower cross bar 220.

[0040] The lifting mechanism 500 is connected to the upper support member 300 and the lower support member 400. The lifting mechanism 500 drives the upper support member 300 to approach the lower support member 400 so that the upper cross bar 210 of the parallelogram mechanism 200 moves forward and downward parallel to the lower cross bar 220. The lifting mechanism 500 drives the upper support member 300 to move away from the lower support member 400 so that the upper cross bar 210 of the parallelogram mechanism 200 moves backward and upward parallel to the lower cross bar 220.

[0041] The seat 600 is connected to the parallelogram mechanism 200. When the upper cross bar 210 moves forward and downward parallel to the lower cross bar 220, the seat 600 moves forward and downward. When the upper cross bar 210 moves backward and upward parallel to the lower cross bar 220, the seat 600 moves backward and upward.

[0042] When a user uses the toilet seat to use the toilet, the lifting mechanism 500 drives the upper support member 300 to move away from the lower support member 400, causing the upper cross bar 210 of the parallelogram mechanism 200 to move away from the lower cross bar 220, so that the seat 600 drives the user to move upward and backward to directly above the toilet.

[0043] After the user finishes using the toilet, the lifting mechanism 500 drives the upper support member 300 to approach the lower support member 400, causing the upper crossbar 210 of the parallelogram mechanism 200 to approach the lower crossbar 220. As a result, the seat 600 drives the user to move downward and forward to directly above the toilet, creating a space between the toilet and the user's feet. This allows the user's feet to move backward, while the user's body moves forward with the seat 600. Consequently, the center of gravity of the user's body is closer to the feet, reducing the force required for the user to stand up and thus facilitating the user to stand up independently.

[0044] In some embodiments, the seat 600 is hinged to the parallelogram mechanism 200, and the liftable toilet seat further includes a drive mechanism 700. The drive mechanism 700 is connected to the seat 600 and the parallelogram mechanism 200, and the drive mechanism 700 drives the seat 600 to rotate relative to the parallelogram mechanism 200.

[0045] By driving the seat 600 to rotate relative to the parallelogram mechanism 200 through the drive mechanism 700, the seat 600 can adjust the tilt angle to facilitate the adjustment of the user's sitting posture, enabling the user's back to support the body weight and putting the user's body in a state similar to zero gravity. This minimizes the pressure on the body and achieves the zero-gravity effect of the toilet seat.

[0046] In some embodiments, the drive mechanism 700 is a linear drive mechanism. The movable end of the drive mechanism 700 is hinged to the seat 600, and the fixed end of the drive mechanism 700 is hinged to the parallelogram mechanism 200.

[0047] After the drive mechanism 700 adjusts the angle of the seat 600, the seat 600 can be supported or fixed by the structure of the drive mechanism 700 itself, reducing the burden on the drive mechanism 700.

[0048] In some embodiments, the fixed end of the drive mechanism 700 is located at the bottom and the movable end is located at the top. The movable end of the drive mechanism 700 is hinged to the rear side of the seat 600, and the fixed end of the drive mechanism 700 is hinged to the rear end of the lower crossbar 220.

[0049] After the drive mechanism 700 pulls the seat 600 to tilt backward to adjust the angle, putting the user in a zero-gravity sitting posture, part of the user's weight is supported by the rear side of the seat 600. The drive mechanism 700 itself supports the rear side of the seat 600 and the rear end of the lower crossbar 220 to prevent the seat 600 from tipping backward and injuring the user in case the drive mechanism 700 is damaged.

[0050] In some embodiments, the parallelogram mechanism 200 is further provided with a front vertical rod 230 and a rear vertical rod 240. The front vertical rod 230 is parallel to the rear vertical rod 240. The bottom end of the front vertical rod 230 is hinged to the front end of the lower crossbar 220, the top end of the front vertical rod 230 is hinged to the front end of the upper crossbar 210, the bottom end of the rear vertical rod 240 is hinged to the rear end of the lower crossbar 220, the middle part of the rear vertical rod 240 is hinged to the rear end of the upper crossbar 210, the top end of the rear vertical rod 240 extends upward and forward above the upper crossbar 210, the bottom of the seat 600 is hinged to the top end of the rear vertical rod 240, and the upper support 300 abuts against the front side of the seat 600.

[0051] When the driving mechanism 700 pushes the seat 600 to rotate forward so that the seat 600 is in a normal state, the bottom of the upper support 300 abuts against the front side of the seat 600 to support the seat 600.

[0052] In some embodiments, the elevating toilet seat is further provided with an adjusting mechanism 800 and a headrest 900. The adjusting mechanism 800 is installed on the top of the seat 600, and the headrest 900 is installed on the adjusting mechanism 800. The position of the headrest 900 in the vertical direction and the front-rear direction is changed by the adjusting mechanism 800.

[0053] The position of the headrest 900 is changed by the adjusting mechanism 800 to adapt to users of different heights, so that the headrest 900 can support the user's head.

[0054] In some embodiments, the adjusting mechanism 800 is provided with a plurality of adjusting members 810 and a plurality of locking members 820. The plurality of adjusting members 810 are hinged in sequence from bottom to top. The adjusting member 810 at the bottom end is connected to the top of the seat 600, and the adjusting member 810 at the top end is connected to the headrest 900. A locking member 820 is installed between every two adjacent adjusting members 810, and the locking member 820 is locked to fix the relative positions of the two adjusting members 810.

[0055] The user can adjust the positions of the plurality of adjusting members 810 to better adapt to the position of the user's head.

[0056] In some embodiments, the lifting mechanism 500 is a linear driving mechanism. The movable end of the lifting mechanism 500 is hinged to the upper support 300, and the fixed end of the lifting mechanism 500 is hinged to the lower support 400.

[0057] The fixed end of the lifting mechanism 500 has a relatively large weight. Hinging the fixed end to the lower support 400 helps to reduce the load on the lifting mechanism 500.

[0058] In some embodiments, a clearance hole extending through in the vertical direction is provided in the middle of the seat 600, and two parallelogram mechanisms 200 are located on the left and right sides of the clearance hole, and the upper support member 300, the lower support member 400, and the lifting mechanism 500 are located in front of the clearance hole.
