Description

Technical Field

[0001] This utility model relates to the field of sofa and chair technology, and in particular to a sofa and chair with an assistive function for getting up. Background Technology

[0002] A sofa chair is a type of chair typically featuring a comfortable seat and backrest, designed to provide a space for relaxation and rest. It is commonly used in living rooms or lounge areas, and can be used in conjunction with a sofa or independently. Sofa chairs come in a variety of materials and designs, including fabric, leather, and wooden frames, catering to the needs of different home or office environments. Traditional sofa chairs require the user to stand up entirely, posing a risk of falls for elderly individuals with weakened lower limb strength. Traditional electrically operated standing devices are complex and expensive. Therefore, this invention proposes a sofa chair with an assisted standing function to address the problems mentioned in the background section. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sofa chair with an assistive standing function.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A sofa chair with an assistive standing function includes a seat and a base. The base is located on the upper side of the base, and the lower front part of the base is rotatably connected to the base. Both sides of the base are provided with a standing handle, and the rear end of the standing handle is rotatably connected to the base. Fixed gears are fixed on both sides of the front of the base. A handle is fixed on the upper front end of the standing handle, and a spur gear is fixed on the lower side of the rear connecting part of the standing handle. A corresponding meshing end face gear is provided on the outer side of the spur gear, and the end face gear is rotatably connected to the base.

[0006] Preferably, the fixed gear is located on the outside of the seat, and the fixed gear corresponds to the position of the transition point on the front side of the seat.

[0007] Preferably, a spur gear is rotatably connected to the left and right sides of the front side of the seat. A synchronous pulley is fixed to the outer side of both the spur gear and the end face gear, and a corresponding synchronous belt is sleeved on the outside of the two synchronous pulleys.

[0008] Preferably, a second spur gear is provided on the lower side of the spur gear, the second spur gear is rotated on the seat, and the second spur gear meshes with the lower fixed gear.

[0009] Preferably, a support plate is rotatably connected to the rear center of the seat, and a number of positioning teeth corresponding to the support plate are provided on the rear side of the seat, and a torsion spring is provided at the junction of the support plate.

[0010] Preferably, the seat has several ventilation holes evenly distributed inside, and a headrest is fixedly installed on the upper rear side of the seat.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model is designed with assisting in getting up as its core function. It is designed for the elderly and people with mobility impairments, taking into account both safety and ergonomics. Its core innovation lies in the mechanical transmission system: through the lifting handle driving a multi-stage transmission structure such as spur gears, end face gears, and synchronous belts, human power is converted into the power for lifting the seat, which not only achieves smooth and precise lifting of the seat, but also avoids the complicated operation of traditional electric equipment.

[0013] 2. The adjustable angle support plate and positioning tooth block combination of this utility model, together with the torsion spring, realizes the adaptive fixation of the back angle. The rear of the seat supports flexible angle adjustment and flattening function, which can meet the needs of reading, resting and other scenarios. The matrix arrangement of ventilation holes improves the air circulation of the seat surface. Combined with the ergonomic headrest design, it effectively relieves fatigue and stuffiness from sitting for a long time.

[0014] 3. The handle to the adapter of this utility model is relatively long, and its power arm is also relatively long. At the same time, the small gear drives the large gear to rotate, and by utilizing the lever principle, it can start a significant lifting effect, so that the user can complete the seat assisted standing up without exerting much effort.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A sofa chair with an assistive standing function includes a seat 1 and a seat 2. The seat 2 is located on the upper side of the seat 1, and the lower front part of the seat 2 is rotatably connected to the seat 1. Both sides of the seat 2 are provided with a standing handle 5. The rear end of the standing handle 5 is rotatably connected to the seat 2. The upper front end of the standing handle 5 is fixed with a grip 7, and the lower rear end of the standing handle 5 is fixed with a spur gear 6. The outer side of the spur gear 6 is provided with a corresponding meshing end face gear 9, and the end face gear 9 is rotatably connected to the seat 2. When the user lies on the seat 2 and needs to get up, he / she can grasp the connected standing handle 5 by the grips 7 on both sides and pry the standing handle 5 open to the left and right to raise the seat 2 on the seat 1, thus making it easier for the user to get up. After the standing handles 5 on both sides are turned outward, the spur gear 6 at the rear end of the standing handle 5 rotates accordingly, and the spur gear 6 drives the outer meshing end face gear 9 to rotate accordingly.

[0022] Fixed gears 8 are fixed on both the left and right sides of the front side of the seat 1. The fixed gears 8 are located on the outside of the seat 2 and correspond to the position of the front joint of the seat 2. Spur gear 12 is rotatably connected to both the left and right sides of the front side of the seat 2. Synchronous pulleys 10 are fixed on the outside of spur gear 12 and end face gear 9. Corresponding synchronous belts 11 are sleeved on the outside of the two synchronous pulleys 10. A corresponding spur gear 2 13 is provided on the lower side of spur gear 12. Spur gear 2 13 is rotated on the seat 2 and meshes with the lower fixed gear 8. When the end face gear 9 rotates, it drives spur gear 12 to rotate through the two outer synchronous pulleys 10 and the corresponding synchronous belt 11. Spur gear 12 drives the lower meshing spur gear 2 13 to rotate. Spur gear 2 13 is driven to rotate by the handle. Spur gear 2 13 rotates on the fixed fixed gear 8, so that the seat 2 rotates on the seat 1, thereby raising the seat 2 on the seat 1, making it convenient for the user to get up.

[0023] A support plate 14 is rotatably connected to the rear center of the seat 1, and several positioning teeth 15 corresponding to the support plate 14 are provided on the rear side of the seat 2. A torsion spring is provided at the junction of the support plate 14. Several ventilation holes 4 are evenly opened inside the seat 2, and a headrest 3 is fixedly installed on the upper rear side of the seat 2. The ventilation holes 4 provide breathability to the seat 2 and improve the comfort of the seat 2. During the rotation of the seat 2, the rear support plate 14 is pressed against the front seat 2 by the torsion spring. The outer side of the support plate 14 is engaged between the two positioning teeth 15 at the corresponding positions to achieve real-time fixation of the angle of the seat 2 after adjustment. When it is necessary to flatten the seat 2, the support plate 14 is rotated out of the tooth groove of the positioning teeth 15, which makes it easy to flatten the seat 2.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
