Description

Technical Field

[0001] This utility model belongs to the field of toilet chair technology, and in particular relates to a toilet chair that is easy to automatically fold. Background Technology

[0002] Toilet chairs are a common device used to assist people with mobility impairments in using the toilet. Most existing toilet chairs employ a folding design to save space, but their folding mechanisms generally rely on two-handed operation: the user must hold the seat with one hand and pull the backrest or support with the other, applying force in both directions to fold it down. This operation requires the user to exert considerable force, which is extremely inconvenient for users with limited mobility or insufficient muscle strength. Furthermore, traditional folding structures are complex, with cumbersome unfolding and folding steps, prone to jamming or inaccurate positioning, further reducing efficiency and safety. Utility Model Content

[0003] (I) Purpose of the utility model

[0004] In order to overcome the above shortcomings, the purpose of this utility model is to provide a toilet chair that is easy to automatically fold, so as to solve the technical problems of existing toilet chairs being inconvenient to fold, requiring a large force to be applied, and having low folding efficiency.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the technical solution provided in this application is as follows:

[0007] An automatic folding toilet chair includes: a front support; a support plate with a first through hole in the middle and hinged to the bottom of the front support; a toilet seat fitted at the first through hole; a toilet seat hinged to the support plate and having a second through hole in the middle that matches the shape of the toilet; a rear support with one end hinged to the bottom of the rear side of the front support; a connecting rod with both sides hinged to the rear support and the upper end hinged to the bottom of the support plate; a positioning seat at the bottom of the support plate, which has a positioning groove that engages with the front support when the support plate is flipped down into place; and a spring hinge with one end connected to the support plate and the other end connected to the connecting rod.

[0008] Through the linkage design of the rear support and the linkage rod, when the toilet chair is unfolded, the spring inside the spring hinge generates elastic force, at which point the positioning seat engages with the front support and will not accidentally flip up. When folding, the user only needs to gently lift the support plate upwards to disengage the positioning seat of the support plate from the front support, and then tilt the toilet chair forward slightly. Under the action of gravity, the rear support drives the linkage rod to swing downwards and forwards in an arc trajectory. The support plate can swing upwards and fold under the pull of the linkage rod and with the elastic force of the spring hinge. This design completely eliminates the limitations of traditional two-handed operation, allowing users who rely on canes or walking aids to complete the folding without freeing their hands, significantly reducing the risk of imbalance or slipping. The toilet chair of this application has a simple structure, which can avoid hygiene hazards or structural jamming caused by misalignment, and ensures smooth and stable folding action.

[0009] In some embodiments, the front support includes: a supporting outer frame and a first connecting rod disposed inside the supporting outer frame and connected to the supporting outer frame at both ends for hinged connection of the support plate, and a support rod disposed inside the supporting outer frame and connected to the supporting outer frame at both ends for supporting the unfolded support plate.

[0010] The outer frame and the first connecting rod form a rigid frame structure, which can effectively distribute the load pressure from the support plate and the user, enhance the overall stability, and the support rod provides vertical support force when the support plate is unfolded, preventing the support plate from sinking due to long-term use or heavy load, ensuring the stability and safety of the toilet chair during use, especially suitable for users with larger body weight.

[0011] In some embodiments, the supporting frame includes: a backrest tube segment of the frame structure, connecting tube segments that are connected to both ends of the backrest tube segment and extend horizontally, and two front chair leg tube segments that are connected to the two connecting tube segments and then bend downwards.

[0012] The backrest tube and the horizontally extending connecting tube form an ergonomic backrest structure, improving user sitting comfort. The downward-sloping design of the front leg tube lowers the center of gravity of the toilet chair, improving its anti-forward tilting ability and maintaining stability even on uneven ground or when the user's center of gravity shifts, preventing accidental tipping over.

[0013] In some embodiments, the rear support includes: two symmetrically arranged rear seat leg segments and a second connecting rod that laterally connects the two rear seat leg segments, wherein each rear seat leg segment first extends laterally and is hinged to the connecting segment, and then bends and extends downward at an angle.

[0014] The symmetrical rear seat leg sections and the second connecting rod form an I-shaped stable structure, significantly improving the torsional resistance of the rear support during folding and preventing deformation caused by uneven stress. The bending design of the rear seat leg sections allows them to naturally fold under the front support when folded, reducing storage space occupation while maintaining a neat appearance after folding, facilitating indoor storage or transportation.

[0015] In some embodiments, it further includes: a reinforcing rod whose two ends extend laterally and are respectively connected to the front seat leg tube segment and the second connecting rod.

[0016] The reinforcing rod forms a lateral rigid connection between the front and rear supports, effectively balancing the forces on both sides and preventing the supports from deforming due to frequent folding or heavy loads. This design significantly improves the overall structural strength and is especially suitable for long-term use scenarios, ensuring that the toilet chair can maintain stability and reliability after multiple openings and closings.

[0017] In some embodiments, there are two symmetrical first connecting rods, each of which is bent into a right-angle structure, with one end connected to the connecting pipe segment and the other end connected to the support rod.

[0018] Improve structural strength.

[0019] The symmetrically distributed right-angle bent first connecting rod can evenly transmit the supporting force, avoid the risk of breakage caused by stress concentration on one side, and ensure that the toilet chair can withstand greater vertical loads when unfolded.

[0020] In some embodiments, the upper surface of the support plate is provided with a first hinge seat that is hinged to the toilet seat, and the bottom of the support plate is provided with a second hinge seat that is hinged to the first connecting rod and the linkage rod respectively.

[0021] The hinged base ensures the hinge accuracy of each component through standardized connection points, reducing motion interference caused by assembly errors.

[0022] In some embodiments, the toilet seat is provided with a first hinge shaft that is hinged to the first hinge seat, and further includes: a torsion spring, which is sleeved on the first hinge shaft and has one end connected to the first hinge seat and the other end hinged to the first hinge shaft.

[0023] Users only need to apply a small initial force to trigger the energy storage or release process of the torsion spring, so that the toilet seat can quickly and automatically flip up or gently return to its original position. This design greatly reduces the requirements for the user's upper limb strength, and is especially suitable for people with muscle weakness or poor limb coordination.

[0024] In some embodiments, a positioning seat is provided on the connecting pipe section at the position corresponding to the rear chair leg pipe section;

[0025] The precise locking design of the positioning seat and the rear seat leg section ensures that all parts are tightly locked after the toilet chair is unfolded, completely eliminating the risk of shaking or displacement during use. Users only need to unfold the support to automatically complete the positioning without manual adjustment, which greatly improves the convenience of operation and is especially suitable for people with weak upper limb strength or poor coordination.

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0039] This utility model provides an automatic folding toilet chair, comprising a front support 1, a support plate 3 with a first through hole in the middle and hinged to the bottom of the front support 1, a toilet 4 fitted at the first through hole, a toilet seat 5 hinged to the support plate 3 and having a second through hole in the middle that matches the shape of the toilet 4, a rear support 2 with one end hinged to the bottom of the rear side of the front support 1, a connecting rod 6 with both sides hinged to the rear support 2 and the upper end hinged to the bottom of the support plate 3, a positioning seat 9 set at the bottom of the support plate 3, which has a positioning groove 901 that engages with the front support 1 when the support plate 3 is flipped down to the position, and a spring hinge 12 with one end connected to the support plate 3 and the other end connected to the connecting rod 6.

[0040] Specifically, the core of the folding action lies in the linkage design between the rear support 2 and the connecting rod 6. When the toilet chair is unfolded, the spring inside the spring hinge 12 generates elastic force, at which point the positioning seat 9 engages with the front support 1, preventing it from accidentally flipping up. When folding, when the user pulls the support plate 3 upwards, causing the positioning seat 9 to disengage from the front support 1, the toilet chair can be tilted forward with one hand, lifting the rear support 2 off the ground. Under the influence of gravity, it swings downwards and forwards in an arc, and the connecting rod 6, hinged to the rear support 2, moves synchronously. Since the upper end of the connecting rod 6 is hinged to the bottom of the support plate 3, its movement trajectory will pull the support plate 3 to fold upwards. In addition, the elastic force generated when the spring inside the spring hinge 12 returns to its original position assists in folding the support plate 3 upwards. The toilet 4 and the seat 5 fold upwards and retract along with the support plate 3.

[0041] Specifically, the spring hinge 12 includes: a first hinge and a second hinge. The first hinge is connected to the support plate 3, and the second hinge is connected to the linkage rod 6. The first hinge has a concave structure and two third hinge shafts are arranged opposite each other in the groove. The second hinge has a sleeve through which the two third hinge shafts pass and rotate. A coil spring is sleeved on each of the two third hinge shafts. One end of the coil spring is connected to the third hinge shaft, and the other end is connected to the sleeve. When the support plate 3 swings downward and engages with the front bracket 1 through the positioning seat 9, the coil spring is stretched and generates elastic force. When the positioning seat 9 disengages from the front bracket 1, the coil spring retracts and resets, causing the first hinge to swing upward. Alternatively, other spring hinge structures can be used. Since the spring hinge 12 is a common component on the market, it will not be described in detail here.

[0042] Specifically, the front support 1 adopts a frame structure to enhance rigidity. Its main body is formed by bending tubing to form a U-shaped backrest 8 profile (backrest tube section 101), and the horizontally extending connecting tube sections 102 on both sides form a load-bearing crossbeam (connecting tube section 102), which is bent downward to form the front seat leg tube section 103.

[0043] Specifically, the outer frame is equipped with a first connecting rod 104 and a support rod 105 at the front and rear.

[0044] Preferably, the support frame has two symmetrically arranged right-angle connecting rods inside, which not only provide hinge points for the support plate 3, but also form a triangular stable structure together with the vertical support rod 105. In particular, the support rod 105 has an arc-shaped groove machined in the middle, which provides sufficient space for the toilet 4 to swing during the folding process, completely eliminating the possibility of component interference.

[0045] Specifically, the rear support 2 adopts a symmetrical layout to enhance torsional resistance. The two rear seat leg sections 201 form an I-beam structure through a second transverse connecting rod 202. Each support leg first extends horizontally and hinges to the connecting tube section 102 of the front support 1, and then bends downward and extends to form a support surface. This design allows the rear support 2 to be naturally tucked under the front support 1 when folded, reducing the overall thickness by approximately 40% after folding.

[0046] Preferably, a reinforcing rod 106 is provided between the front and rear supports 2. The two ends of the rod are connected to the front support leg and the crossbar of the rear support 2, respectively, to form a stable quadrilateral frame, which significantly improves the lateral deformation resistance.

[0047] Preferably, a positioning seat 9 is also provided on the connecting pipe section 102 of the front support 1 at the position corresponding to the rear seat leg section 201. When the toilet chair is fully unfolded, the positioning seat 9 can engage with the rear seat leg section 201 to form a physical lock. This mechanism can effectively prevent the displacement of parts due to accidental contact during use.

[0048] Specifically, the upper end face of the support plate 3 is provided with a first hinge seat 13, which is hinged to the first hinge shaft 14 on the toilet seat 5.

[0049] Preferably, a torsion spring is provided inside the first hinge seat 13, and the torsion spring is sleeved on the first hinge shaft 14 of the toilet seat 5. One end of the torsion spring is connected to the first hinge seat 13, and the other end is connected to the first hinge shaft 14. When the toilet seat 5 is flipped downward, the torsion spring deforms and generates torque; when the toilet seat 5 is flipped up, the user only needs to give the toilet seat 5 a small upward force, and with the assistance of the torsion spring, the toilet seat 5 can quickly and automatically flip up to the predetermined position, at which point the toilet 4 can be removed.

[0050] The front bracket 1 and the rear bracket 2 can be hinged to each other via the second hinge shaft 11.

[0051] Preferably, each hinge point at the bottom of the support plate 3 uses a standardized second hinge seat 10 to achieve a precise fit with the first connecting rod 104 and the linkage rod 6. These cast second hinge seats 10 have embedded self-lubricating bearings to ensure smooth operation even during frequent folding.

[0052] Preferably, the toilet seat 5 is covered with an antibacterial soft padding layer, and the edges are designed with a curved edge, which not only improves comfort but also prevents clothing from snagging. The backrest tube 101 of the front support 1 is wrapped with high-density sponge to form a backrest 8, which is designed to conform to the curve of the human back to provide stable support for the user. Rotatable armrests 7 can also be set in the backrest tube 101. When the toilet chair is in use, the armrests 7 can be rotated to a horizontal position, and when the toilet chair is folded, the armrests 7 can be rotated upwards.

[0053] Through the aforementioned structural innovations, this toilet chair achieves a revolutionary one-handed folding mechanism. Actual testing shows that ordinary users can complete the folding action within 3 seconds. Once unfolded, all components automatically lock into place, requiring no additional adjustments. The overall size is reduced to one-third of its unfolded state when folded, allowing for easy storage under the bed or in a corner, making it particularly suitable for living environments with limited space.

[0054] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
