Description

Technical Field

[0001] This utility model relates to the field of wheelchair technology, and more specifically, to a wheelchair that facilitates getting up. Background Technology

[0002] A wheelchair is a device that provides basic mobility and support assistance to people with lower limb dysfunction or limited mobility. It is widely used in hospitals, rehabilitation centers, nursing homes, and home care settings. Traditional wheelchairs typically consist of a seat, armrests, backrest, footrests, and wheels, and are primarily driven manually or electrically to assist users in daily activities both indoors and outdoors. With the development of an aging society and the increasing demand for comfort and autonomy, wheelchair design is gradually evolving towards multifunctionality, personalization, and human-centered design.

[0003] Existing wheelchairs still have significant limitations in leg support and standing assistance. For example, Chinese patent CN211460894U discloses a wheelchair whose footrest structure can be retracted when standing up, but it cannot coordinate with the standing action. Currently, most wheelchairs have fixed footrest structures, which cannot flexibly adjust the angle or height according to changes in the user's body position. This results in ineffective leg support when the user is lying down or standing up, easily leading to problems such as legs dangling, unstable posture, or discomfort, affecting the comfort and safety of use. Although some wheelchairs are equipped with adjustable leg rest components, their adjustment methods are limited and it is difficult to achieve coordinated linkage with the user's body movements, failing to effectively assist the user in smoothly completing lying down or standing up, thus affecting the practicality and assistive effect of the wheelchair.

[0004] Therefore, this application proposes a wheelchair that facilitates getting up. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wheelchair with leg support adjustment function, which can help users get up or lie on their backs and make it easier to get up.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A wheelchair that facilitates getting up includes a seat, on which a support assembly is mounted, the support assembly including a support, and a set of rollers rotatably connected to the bottom positions of both sides of the seat. Two sets of leg support assemblies are provided on the side of the support assembly away from the rollers, and the two sets of leg support assemblies are symmetrically arranged.

[0008] The leg support assembly includes a connector connected to one side of the bracket. A telescopic cylinder is rotatably connected to the bracket. A connecting block is rotatably connected to the output end of the telescopic cylinder. An outer rod is provided on the top of the connecting block. A leg support plate for placing the legs is provided on the top of the outer rod.

[0009] The present invention is further configured such that: the outer rod is a cylinder with one end closed, and an inner rod is slidably connected inside the outer rod.

[0010] The present invention is further configured such that: a vertical rod is connected to the end of the inner rod away from the outer rod, the inner rod is arranged perpendicularly to the vertical rod, and a foot pedal is connected to one end of the vertical rod.

[0011] The present invention is further configured such that: the leg support plate includes a horizontally arranged outer leg support plate, the outer leg support plate has a cavity, and a set of protruding rails are respectively arranged on both sides of the cavity of the outer leg support plate.

[0012] The present invention is further configured such that: an inner support leg plate is slidably connected inside the outer support leg plate, and two sets of grooves are provided at the bottom of the inner support leg plate. The grooves are adapted to the shape of the convex rail, and the inner support leg plate can slide relative to the convex rail through the grooves.

[0013] The present invention is further configured such that: a fastening bolt is provided through the outer support leg plate, and the fastening bolt abuts against the inner support leg plate.

[0014] The present invention is further configured such that: the seat includes a seat arranged in a horizontal direction, the seat is made of a supportive fabric, and a backrest is provided on one side of the seat.

[0015] The present invention is further configured such that: handles are respectively provided on both sides of the top of the bracket, the handles are symmetrically arranged, and a set of crossbars are respectively installed on both sides of the bracket, with handrails slidably connected to the crossbars.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. This utility model features a telescopic cylinder mounted at an angle on the wheelchair frame. When the user needs to stand up, the cylinder is driven to retract by the control system. Its output end drives the connecting block to rotate downwards, causing the entire leg support assembly to tilt downwards. During this process, the front end of the leg support plate gradually approaches the ground or naturally tilts, allowing the user's legs to hang naturally, thus reducing the support force required on the legs and waist when standing up. This function is particularly suitable for users with weak lower limb muscles, limited mobility, or those requiring assisted standing, significantly improving the ease and independence of standing up, reducing the need for caregivers, and enhancing the self-care ability and dignity of wheelchair users.

[0018] 2. When the user needs to lie down to rest, relax their legs, or elevate their legs, the wheelchair's telescopic cylinder can be extended, pushing the connecting block upwards, thereby gradually rotating the entire leg support assembly to a near-horizontal position. At this time, the leg support plate forms a continuous leg support surface, providing complete support for the legs in a non-suspended state, effectively preventing poor blood return, lower limb edema, or discomfort caused by prolonged sitting. Simultaneously, the supine position allows the user to rest or undergo short-term lying-down treatment in the wheelchair without the need for additional transfer to a bed, effectively enhancing the wheelchair's functionality and comfort, and meeting various needs for clinical care and daily use.

[0019] 3. The leg support structure adopts a double-layer sliding design with an outer leg support and an inner leg support. The outer leg support is hollow and contains a guide rail, while the bottom of the inner leg support has a groove structure that matches the guide rail, ensuring stability and positioning accuracy during sliding. By adjusting the position of the inner leg support, the overall length of the leg support can be extended or shortened, thus achieving a precise fit for different users' leg lengths. This structure enhances the wheelchair's adaptability in multi-user scenarios. Attached Figure Description

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0032] Example 1, please refer to Figures 1-6 The present invention provides the following technical solution:

[0033] Specifically, it refers to a wheelchair that facilitates getting up, designed to provide auxiliary support and leg support for people with mobility impairments during sitting or getting up, improving comfort and safety. It includes a seat 1, on which a support assembly 2 is installed to support the user's upper body and connect with other functional components.

[0034] The support assembly 2 includes an upright support 21, which comprises three sets of horizontal bars and one vertical bar. The support 21 is fixedly connected to the rear of the seat 1 and extends through both sides of the seat. A set of rollers 3 are rotatably connected to the bottom of both sides of the seat 1 for the movement and support of the wheelchair. Preferably, the outer edge of the rollers 3 is provided with anti-slip grooves 31 to improve the wheelchair's grip and anti-slip performance on different surfaces.

[0035] On the side of the support assembly 2 away from the roller 3, that is, near the lower front end of the seat 1, there are two sets of leg support assemblies 4. The two sets of leg support assemblies 4 are installed symmetrically on the left and right sides, respectively corresponding to the user's left and right legs, and are used to support and adjust the leg posture when sitting.

[0036] The leg support assembly 4 includes a connector 41 rotatably connected to one side of the bracket 21, a connecting outer rod 44 rotatably connected to the connecting rod 41, a connecting block 43 at the bottom of the connecting outer rod 44, and a telescopic cylinder 42 for driving rotatably connected to the connecting block 43.

[0037] Please see Figure 4One end of the telescopic cylinder 42 is rotatably mounted on the bracket 21, and the output end is rotatably connected to the connecting block 43. The telescopic cylinder 42 is inclined forward and downward, and its telescopic movement drives the connecting block 43 to rotate around the bracket 21 as a reference point. An outer rod 44 is fixedly connected to the top of the connecting block 43. As the telescopic cylinder 42 drives the connecting block 43 to swing, the angle of the outer rod 44 relative to the connecting member 41 changes. This structure can quickly adjust the support angle of the leg support assembly 4 according to the user's needs for standing up or leg support, thereby improving the stability of leg support and the convenience of standing up.

[0038] Furthermore, the outer rod 44 is a hollow cylindrical structure closed at one end, with a leg support plate 48 connected to its top. To achieve the leg support length adjustment function, an inner rod 45 is slidably connected inside the outer rod 44. The inner rod 45 can slide and extend along the axial direction of the outer rod 44 to adapt to the personalized support needs of users with different heights or leg lengths. A vertically arranged vertical rod 46 is fixedly connected to the end of the inner rod 45 away from the outer rod 44. The vertical rod 46 is perpendicular to the inner rod 45, and a foot pedal 47 is installed at its lower end to provide support for the user's feet.

[0039] Specifically, when a user needs to rest supine or lie flat with legs raised, the telescopic cylinder 42 located on the bracket 21 extends, and its output end pushes the connecting block 43 to rotate upward. Since the connecting block 43 is fixedly connected to the outer rod 44, and the outer rod 44 is rotatably connected to the bracket 21, the outer rod 44 swings upward as a whole under the action of the connecting block 43, causing the leg support assembly 4 to rotate upward and gradually approach a horizontal state. At this time, the user's legs can be naturally placed flat on the leg support plate 48, and the legs and body form a support posture that is almost straight, improving comfort and making it suitable for rehabilitation scenarios that require rest or leg elevation.

[0040] Please see Figure 4 To accommodate users with different leg lengths, an adjustable structure is incorporated into the leg support plate 48. Specifically, the leg support plate 48 is a double-layer sliding structure, comprising a horizontally positioned outer leg support plate 481. The outer leg support plate 481 has a hollow interior, with a set of symmetrical convex rails 483 arranged on both sides of the cavity along the sliding direction. Fastening bolts 49 penetrate the sidewalls of the outer leg support plate 483, with one end of each bolt abutting against an inner leg support plate 482. To achieve leg length adjustment, an inner leg support plate 482 is slidably connected inside the outer leg support plate 481. The bottom of the inner leg support plate 482 has two sets of grooves 484 that match the shape of the convex rails 483. By using the grooves 484 to guide and limit sliding along the convex rails 483, the inner leg support plate 482 can move axially relative to the outer leg support plate 481 within a certain range, enabling personalized adjustment of the leg support length to accommodate users of different heights.

[0041] When a user needs to get up from a supine position, the telescopic cylinder 42 begins to retract, and its output end drives the connecting block 43 to rotate downward, which in turn causes the outer rod 44 and the overall leg support assembly 4 to rotate downward. The leg support plate 48 presents a certain forward and downward tilt angle, so that the user's legs form a natural hanging posture, thereby reducing the support force required for the legs and waist when getting up, which is conducive to the user's feet landing on the ground and assists the user in completing the process of getting up.

[0042] Please see Figure 1 The seat 1 includes a seat 12 arranged horizontally. The seat 12 is preferably made of a supportive, high-strength fabric that provides both comfort and flexibility. A backrest 11 is provided on the rear side of the seat 12 to support the user's back and improve sitting stability.

[0043] A handle 22 is provided on each of the top two sides of the bracket 21. The two handles 22 are symmetrically arranged and installed perpendicular to the bracket 21. Users can push the wheelchair to move by gripping the handles 22, making it easy to control the direction of travel. A set of crossbars 23 is installed on the left and right sides of the bracket 21. Armrests 24 are slidably connected to the crossbars 23. The armrests 24 can be adjusted forward and backward on the crossbars 23 to accommodate users of different heights or arm lengths. When the user needs to get up, they can first sit on the seat 1 and adjust the armrests 24 outward to ensure the length of the gripping end, preventing falls caused by leaning forward when getting up, and ensuring optimal coordination to avoid discomfort. With the synergistic effect of the armrests 24 and the leg support assembly 4, better support and assistance are provided for the user, making the process of getting up more convenient and quick.

[0044] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
