Description

Technical Field

[0001] The utility model relates to the technical field of chairs, in particular to a dual-state work kneeling chair. Background Art

[0002] The kneeling chair's design incorporates ergonomic principles to provide users with a more comfortable and healthy sitting experience. By adjusting the seat's angle and height, as well as the position of the backrest and kneeling support, the kneeling chair effectively distributes body weight, reducing pressure on the waist, back, and knees. This design not only helps alleviate fatigue from prolonged sitting but also, to a certain extent, prevents and improves sitting-related health issues, such as cervical and lumbar spondylosis.

[0003] Traditional kneeling chairs usually only provide a kneeling usage mode. This design may be very suitable in specific situations, but in daily office or home environments, kneeling for long periods of time may cause discomfort in the knees and feet, limiting the user's comfort. Traditional kneeling chairs often lack the convenience of switching between different usage modes. If the user needs to change the sitting posture, the user may need to completely leave the chair and readjust the posture, which is not only troublesome but may also interrupt the rhythm of work or rest.

[0005] (2) Technical solution: In order to achieve the above-mentioned purpose of being able to flexibly switch between different states to meet different needs, the utility model provides the following technical solution: a dual-state work kneeling chair, which has two forms: kneeling mode and chair mode, including a seat bracket and a kneeling bracket, the upper end of the seat bracket is provided with a sitting surface, and the sitting surface is fixedly connected to the seat bracket; the upper surface of the kneeling bracket is fixedly connected to the kneeling surface, one end of the kneeling bracket is hinged to the lower end of the seat bracket through a rotating mechanism, and the kneeling bracket has the freedom to rotate upward along the rotating mechanism, and the other end of the kneeling bracket is provided with a locking structure, and the upper end of the seat bracket is provided with a locking block, and the locking structure is adapted to the locking block from bottom to top; when the kneeling chair is in the kneeling mode, the kneeling bracket is placed parallel to the ground, and at this time the kneeling surface is parallel to the ground; when the kneeling chair is in the chair mode, the kneeling bracket is supported and connected to the blocking block by the locking structure.

[0006] Preferably, a first fixing belt is provided between the sitting surface and the chair support, and a second fixing belt is provided between the kneeling support and the kneeling surface, and both the first fixing belt and the second fixing belt are annular elastic belts.

[0007] Preferably, the rotating mechanism is a rotating shaft or a hinge mechanism.

[0008] Preferably, the interior of the sitting surface and the kneeling surface are filled with soft fillers, and the upper surfaces of the sitting surface and the kneeling surface are made of flexible materials.

[0009] Preferably, a reinforcing rib is provided on the side of the seat bracket close to the ground, the bottom surface of the reinforcing rib is level with the ground, and the reinforcing rib is fixedly connected to the seat bracket.

[0010] Preferably, a groove is provided on the upper surface of the locking structure, and when the locking block is connected to the locking structure, the lower surface of the locking block is in contact with the upper surface of the groove of the locking structure.

[0011] Preferably, the outer side of the upper end of the seat bracket is a downward inclined structure; the lower surface of the block and the upper surface of the locking structure groove are both inclined surfaces, and the lowest point of the inclined surface close to the seat bracket is lower than the lowest point close to the outer side.

[0012] Preferably, the width of the groove formed on the upper surface of the locking structure is the same as the width of the locking block.

[0013] Preferably, the kneeling bracket is an H-shaped structure, and the number of the blocking structures is two, which are respectively located at the front ends of both sides of the kneeling bracket; the upper end of the seat bracket is H-shaped, and the width of the upper end of the seat bracket is the same as the width of the kneeling bracket, and the blocking blocks are installed at the front ends of both sides of the upper end of the seat bracket.

[0014] (III) Beneficial effects: Compared with the prior art, the present invention provides a dual-state work kneeling chair with the following beneficial effects:

[0015] 1. This dual-mode work kneeling chair connects the seat frame and the kneeling frame with a rotating mechanism, so that the kneeling frame can rotate upward along the rotating mechanism. This design allows the user to easily flip the kneeling frame upward when the user does not need to kneel, until the locking structure at its outward end fits into the corresponding locking block at the seat frame, thereby smoothly completing the transition to the kneeling chair form. When the kneeling frame is laid flat, it forms a straight line connected to the rotating mechanism, and the contact surfaces of the two are in contact. Therefore, the kneeling frame has no downward rotational freedom. This design prevents users from encountering the interference of the kneeling frame bending downward when carrying the kneeling chair. In addition, because the width of the groove on the upper surface of the locking structure is the same as the width of the locking block, and the lower surface of the locking block and the upper surface of the groove of the locking structure are both inclined surfaces, the lowest point of the inclined surface near the seat frame is lower than the lowest point near the outer side. Therefore, when the kneeling frame flips upward, it also limits itself and transforms into a part of the support frame in the seat mode, thereby changing its function and increasing the overall stability of the utility model.

[0016] 2. This dual-mode work kneeling chair strengthens the overall structure of the kneeling chair by providing reinforcing ribs at the contact point between the seat frame and the ground, and the lower surface of the reinforcing ribs is flat and parallel to the ground. At the same time, when the kneeling chair is in the seat mode, the contact between the reinforcing ribs and the ground is smoother, which improves the comfort of the user.

[0017] 3. This dual-state work kneeling chair has a groove on the upper surface of the locking structure and then matches the size of the locking block with the groove. This design ensures that the locking block can be completely and accurately embedded in the groove, avoiding shaking or misalignment during connection, thereby improving the stability and safety of the overall structure; the lower surface of the locking block and the upper surface of the locking structure groove are both inclined surfaces, and the lowest point of the inclined surface close to the seat bracket is lower than the lowest point close to the outside. This design ensures that the kneeling chair forms a smoother sliding or rotating action when connecting or disconnecting the locking block and the locking structure, reducing friction and resistance. At the same time, because the outer side of the upper end of the seat bracket is a downward inclined structure, when the user sits on the seat bracket, the vertical kneeling bracket is subjected to a force biased inward that is greater than the force biased outward. Therefore, this design also limits the kneeling bracket in the horizontal direction, which helps to ensure the tightness and stability of the connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 The invention relates to a dual-mode work kneeling chair, which has two modes: a kneeling mode and a seat mode, and includes a seat frame 1 and a kneeling frame 2. The upper end of the seat frame 1 is provided with a sitting surface 11, and the sitting surface 11 and the seat frame 1 are fixedly connected by bolts; the upper surface of the kneeling frame 2 is fixedly connected with a kneeling surface 21, and the inside of the sitting surface 11 and the kneeling surface 21 are filled with soft fillings such as cotton, and the upper surfaces of the sitting surface 11 and the kneeling surface 21 are made of flexible materials such as artificial leather to ensure the comfort of the user when sitting; one end of the kneeling frame 2 is hinged to the lower end of the seat frame 1 through a rotating mechanism 3, and the rotating mechanism 3 is a rotating shaft or hinge mechanism, and the kneeling frame 2 has the freedom to rotate upward along the rotating mechanism 3. When the kneeling frame 2 is laid flat, it forms a connected straight line with the rotating mechanism 3, and the contact surfaces of the two are in contact, so the kneeling frame 2 has no downward rotation freedom. This design makes it easier for users to move the kneeling chair. When the kneeling chair is in the seat mode, the user lifts the kneeling bracket 2 upward along the rotating mechanism 3, and uses the locking structure 4 to connect with the block 12, so as to realize the shape switching and transform the kneeling bracket 2 into the support frame in the seat mode, and transform it into a part of the support frame in the seat mode, thereby increasing the overall stability of the utility model while changing the function.

[0025] See also Figure 1 and 3 -4. A first fixing belt 13 is provided between the seat surface 11 and the chair frame 1, and a second fixing belt 22 is provided between the kneeling frame 2 and the kneeling surface 21. Both the first fixing belt 13 and the second fixing belt 22 are annular elastic belts; the first fixing belt 13 is used to provide tension to the user's ankle, reduce pressure on the foot, and prevent insufficient blood supply; the second fixing belt 22 is used to fix the user's calf to prevent safety hazards caused by slipping when kneeling.

[0026] See also Figure 1 and 3 -4. A reinforcing rib 23 is provided on the side of the seat frame 1 close to the ground. The bottom surface of the reinforcing rib 23 is level with the ground, so that when the kneeling chair is in the seat mode, the contact between the reinforcing rib 23 and the ground is smoother. The reinforcing rib 23 and the seat frame 1 are fixedly connected, thereby strengthening the overall structure of the kneeling chair.

[0027] See also Figure 2 , a groove is provided on the upper surface of the locking structure 4. When the block 12 is connected to the locking structure 4, the lower surface of the block 12 is in contact with the upper surface of the groove of the locking structure 4. This design ensures that the block 12 can be completely and accurately embedded in the groove, avoiding shaking or misalignment during connection, thereby improving the stability and safety of the overall structure; the outer side of the upper end of the seat bracket 1 is a downward inclined structure, so that when the user sits on the seat bracket 1, the force direction of the kneeling bracket 2 is biased towards the inside; the lower surface of the block 12 is in contact with the upper surface of the groove of the locking structure 4 They are all inclined surfaces, and the lowest point of the inclined surface close to the seat bracket 1 is lower than the lowest point close to the outside. This design also limits the kneeling bracket 2 in the horizontal direction, which helps to ensure the tightness and stability of the connection. At the same time, this design also ensures that the kneeling chair forms a smoother sliding or rotating action when connecting or disconnecting the block 12 and the locking structure 4, reducing friction and resistance; the width of the groove opened on the upper surface of the locking structure 4 is the same as the width of the block 12, ensuring that the block 12 can be completely and accurately embedded in the groove, avoiding shaking or misalignment during connection.

[0028] See also Figure 1 and 3 -4, the kneeling bracket 2 is an H-shaped structure, and there are two clamping structures 4, which are respectively located at the front ends of both sides of the kneeling bracket 2; the upper end of the seat bracket 1 is H-shaped, and the width of the upper end of the seat bracket 1 is the same as the width of the kneeling bracket 2. The clamping blocks 12 are installed at the front ends of both sides of the upper end of the seat bracket 1, so that the kneeling chair forms a symmetrical structure as a whole, and both sides are fixed at the same time, and the structure is more stable.

[0029] Working principle: When the user needs to kneel, the kneeling bracket 2 is rotated downward along the rotating mechanism 3 to separate the locking structure 4 from the blocking block 12, and then the kneeling bracket 2 is placed flat on the ground, the knees are placed on the kneeling surface 21, the calves and ankles are respectively put into the second fixing belt 22 and the first fixing belt 13, and finally the buttocks are placed on the sitting surface 11 of the chair bracket 1; when the user does not need to kneel, the kneeling bracket 2 is flipped upward along the rotating mechanism 3 to connect the locking structure 4 with the blocking block 12. After confirming that the connection is stable, the kneeling chair realizes the conversion from kneeling mode to chair mode. At this time, the kneeling chair can be used as a workbench and a chair.
