[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0027] Example

[0028] Combination Figures 1 to 6 This embodiment provides an anti-tipping sitting / reclining device, including a base 1 and a frame 2 disposed on the base 1. The frame 2 includes at least a back support 3 whose angle can be freely changed, and the back support 3 can switch between an inclined state and a horizontal state. A corresponding anti-tipping member 4 is provided on the base 1. The anti-tipping member 4 is adapted to abut against the back support 3 when the back support 3 is flipped backward to a horizontal state, so that the back support 3 in the inclined state can be quickly fixed in its horizontal state after rotation, thereby preventing the frame 2 from tipping backward.

[0029] Compared to the single adjustment method of the existing frame 2, in this embodiment, the back support 3 on the frame 2 is configured to be able to change states relatively freely, so that users can easily adjust the angle of the bed back, making it convenient to change from lying down to half sitting, sitting upright and other postures. Compared with the traditional frame 2, the convenience and comfort of adjustment are improved.

[0030] The tilt prevention component 4 ensures that the back support 3 can be accurately and quickly switched between the inclined and horizontal positions. When the back support 3 is rotated from the inclined position to the horizontal position, the tilt prevention component 4 can quickly position and stabilize the position of the back support 3, ensuring that any switch can be accurately made, avoiding the problem of inaccurate angle or positional deviation that may exist when the angle is changed in traditional sitting and reclining beds.

[0031] For users who need to frequently adjust their sitting or lying angles, such as the elderly, patients, or those with mobility impairments, the tilt-prevention component 4 simplifies the entire adjustment process. Users no longer need to go through multiple steps to ensure that the back support 3 can accurately remain in a horizontal position. The tilt-prevention component 4 can automatically lock and stabilize the angle, greatly improving the convenience of operation. In particular, it can easily and quickly switch the horizontal angle without external assistance.

[0032] Therefore, the tilt prevention component 4 can ensure that the back support 3 can be accurately and quickly switched between the inclined and horizontal positions. When the back support 3 is rotated from the inclined position to the horizontal position, the tilt prevention component can quickly position and stabilize the position of the back support 3, ensuring that any switch can be accurately made, avoiding the problem of inaccurate angle or positional deviation that may exist when the angle is changed in traditional sitting and reclining beds.

[0033] like Figures 2 to 4As shown, in this embodiment, the tilt prevention component 4 includes at least one abutment arm 5 extending upward from the base 1, and a support end face 6 disposed on the upper end of the abutment arm 5. The support end face 6 is adapted to abut against the back support 3. When the back support 3 rotates to a horizontal position, the support end face 6 provides precise contact and support, ensuring that the back support 3 is stably fixed in a horizontal position after rotation. It also prevents the back support 3 from accidentally moving or swinging due to external forces or its own weight. Furthermore, the support end face 6 effectively prevents the back support 3 from being not completely fixed, thereby ensuring the stability of the bed frame.

[0034] In addition, the abutment arm 5 achieves limit locking by contacting the back support 3. Compared with the traditional mechanical locking device, this contact support method makes the limiting process simpler and more efficient, while also achieving efficient support.

[0035] Preferably, a rubber pad is provided on the support end face 6. The rubber pad can effectively reduce wear or damage to the surface of the back support 3 when the support end face 6 contacts the back support 3. It also provides a certain amount of friction to prevent the support end face 6 from sliding or shifting when in contact with the back support 3. It also has a certain shock absorption effect, effectively absorbing some of the impact force when the support end face 6 contacts the back support 3, reducing vibration or noise generated during adjustment. Preferably, a soft rubber pad can provide a softer and gentler support for the back support 3, avoiding the discomfort caused by hard materials directly contacting the back.

[0036] Furthermore, the abutment arms 5 are configured as a pair spaced apart in the left-right direction. They can be used to abut against the back edge of the back support 3 respectively. Thus, the two abutment arms 5 and their supporting end faces 6 abut against the back edge of the back support 3 respectively, providing a more balanced support force. Compared with a single support method, the two abutment arms 5 distributed on both sides of the back support 3 can effectively distribute the weight load of the back support 3, avoiding tilting or instability caused by concentration on one side, thereby further improving the stability of the entire bed frame.

[0037] like Figures 3 to 6As shown, in this embodiment, the frame 2 further includes a seat support 7 and a leg support 8. The leg support 8 is pivotally connected to the front end of the seat support 7, the seat support 7 is pivotally connected to the base 1, and the back support 3 is pivotally connected to the seat support 7. The seat support 7 is rotatably mounted on the base 1, the leg support 8 is pivotally connected to one end of the seat support 7, and the back support 3 is pivotally connected to the other end of the seat support 7. By independently adjusting the seat support 7, back support 3, and leg support 8 of the frame 2, the user can adjust the usage position according to personal needs, thus adapting to different sitting and lying postures, greatly improving comfort and experience. In particular, the seat support 7 can be freely switched between horizontal and upward tilting positions, and the back support 3 and leg support 8 can also swing independently, significantly improving the flexibility of the entire frame 2 and meeting diverse usage needs.

[0038] Furthermore, a first push rod 10 is connected between the leg support 8 and the seat support 7. The first push rod 10 is driven to extend and retract to change the angle between the leg support 8 and the seat support 7. A second push rod 9 is connected between the seat support 7 and the base 1. The second push rod 9 is driven to extend and retract to change the angle between the seat support 7 and the base 1. A third push rod 11 is connected between the back support 3 and the base 1. The third push rod 11 is driven to extend and retract to change the angle between the back support 3 and the base 1. The coordinated operation of multiple push rods allows the frame 2 to easily adjust the angles of its individual parts without manual force, making it convenient to use and reducing operational complexity. It is not limited to traditional bed rest functions but can also be adjusted to a suitable sitting angle as needed, providing a flexible user experience for activities such as reading, watching TV, and resting. It can provide personalized adjustments for different users, especially for the elderly, patients in recovery, or long-term bedridden patients, offering better comfort and health support.

[0039] In this embodiment, the second push rod 9 is configured as an angled push rod. The angled push rod is obliquely positioned on the base 1 and connected to the seat support 7 near the leg support 8. Its output shaft is hinged to the seat support 7 for flexible switching between states. Specifically, one end of the angled push rod is fixed to the base 1, and the other end is hinged to the seat support 7, having an oblique angle relative to the base 1. This allows the seat support 7 to smoothly and flexibly switch between a horizontal position and an upwardly tilted position. Due to the oblique setting of the push rod, a large angle range and adjustment flexibility are provided to meet the needs of different users in various activities. Preferably, the oblique angle of the push rod is between 30° and 60°.

[0040] In this embodiment, the first push rod 10 is configured as a straight push rod. The straight push rod is horizontally placed on the base 1, and its output shaft is hinged to the leg support 8. Obviously, the straight push rod is used to provide a stable linear driving force, so that the leg support 8 can swing freely within a preset range according to the user's needs, ensuring a smooth and comfortable adjustment process.

[0041] In this embodiment, the third push rod 11 includes a rotating component 12 and a piston rod 13. The rotating component 12 is disposed on the base 1, and the output shaft of the piston rod 13 is hinged to the back support 3. The rotating component 12 drives the piston rod 13 to rotate freely for extension and retraction. By rotating the piston rod 13 through the rotating component 12, the back support 3 can be flexibly adjusted in angle, and the piston rod 13 can extend and retract freely, thereby achieving effective adjustment of the back support 3. This provides greater flexibility and adjustment range, allowing the back support 3 to smoothly transition from one inclined position to another, or to a horizontal position, avoiding excessive and drastic displacement and improving user comfort.

[0042] It should be noted that the frame 2 is configured to switch between at least one sitting posture and at least one lying posture. The lying posture includes at least one of a zero-gravity posture, a reclining posture, and a flat lying posture. Furthermore, the sitting / lying device can be further equipped with a rhythmic mechanism (not shown) on the base 1 for use as a rhythmic bed. Moreover, the seat support 7, leg support 8, and back support 3 of the frame 2 are flexibly adjustable in angle (within the acute angle range), allowing the frame 2 to have a normal use position, a flat use position, and a reclining use position.

[0043] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
