Detailed Implementation

[0034] The following are specific embodiments of this application, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments.

[0035] refer to Figure 1 and Figure 2 This application provides a cane for assisting in sitting up, including a cane body 100, a first support rod 200, a support assembly 300, and a gas spring 400.

[0036] The cane body 100 is the main part of the cane. The material of the cane body 100 can be aluminum alloy, carbon fiber or wood, taking into account both lightness and strength.

[0037] One end of the first support rod 200 is telescopically connected to the cane body 100, thereby adjusting the overall length of the first support rod 200 and the cane body 100. The other end of the first support rod 200 is used to support the support surface, which can be the ground or the like.

[0038] The support assembly 300 includes a second support rod 310 and a third support rod 320. One end of the second support rod 310 and one end of the third support rod 320 are hinged to the cane body 100. The other ends of the second support rod 310 and the third support rod 320 can be used to support the ground. The second support rod 310 and the third support rod 320 are both hinged to the other end of the first support rod 200. One end of the gas spring 400 is connected to the cane body 100, and the other end of the gas spring 400 is connected to the first support rod 200. The gas spring 400 drives the first support rod 200 to move so that the second support rod 310 and the third support rod 320 move closer to each other or further apart.

[0039] The first support rod 200 is driven to extend and retract by the gas spring 400. The first support rod 200 is hinged to the second support rod 310 and the third support rod 320. When the user needs to sit up, the gas spring 400 provides power to move the first support rod 200, which in turn drives the second support rod 310 and the third support rod 320 to move closer or further apart, so that the first support rod 200, the second support rod 310 and the third support rod 320 can all be supported on the support surface. This linkage structure can provide stable support for the user, help the user smoothly change between sitting and standing postures, and reduce the risk of falling due to insufficient strength or unstable movement when the user gets up.

[0040] In this application, the cane for assisting sitting up is relatively simple to operate. The user only needs to use their own movements and the drive of the gas spring 400 to achieve the sitting-up assistance function, without complicated operating steps or additional auxiliary tools. This makes the cane suitable not only for home environments, but also for use in public places, hospitals, and other places, improving the versatility and practicality of the cane.

[0041] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The support assembly 300 has a first state and a second state. When the support assembly 300 is in the first state, the end of the second support rod 310 away from the cane body 100 and the end of the third support rod 320 away from the cane body 100 are both spaced apart from the support surface. When the support assembly 300 is in the second state, the end of the second support rod 310 away from the cane body 100 and the end of the third support rod 320 away from the cane body 100 are both supported on the support surface.

[0042] Specifically, when the support assembly 300 is in the first state, the second support rod 310 and the third support rod 320 are suspended, reducing the contact points with the support surface and making the cane more flexible when moving, facilitating the user to adjust its position or walk; at this time, the cane can be used as a regular walking aid, adaptable to flat or slightly inclined ground. When the support assembly 300 is in the second state, the first support rod 200, the second support rod 310, and the third support rod 320 are all in contact with the support surface, forming a multi-point support structure, significantly improving the stability of the cane, especially suitable for scenarios where the user needs to sit up, stand up, or requires additional support.

[0043] By switching the support state of the support component 300, users can use the stable support point of the cane to help them get up, avoiding the risk of tipping over or slipping due to single-point support.

[0044] In this embodiment, the support assembly 300 further includes a hinge seat 330, a first connecting rod 340, and a second connecting rod 350. The hinge seat 330 is fixedly connected to the rod body 100. One end of the second support rod 310 is hinged to the hinge seat 330, and one end of the third support rod 320 is hinged to the hinge seat 330. One end of the first connecting rod 340 is hinged to the second support rod 310, and the other end of the first connecting rod 340 is hinged to the first support rod 200. One end of the second connecting rod 350 is hinged to the third support rod 320, and the other end of the second connecting rod 350 is hinged to the first support rod 200. Through the mechanical linkage design of the hinge seat 330, the first connecting rod 340, and the second connecting rod 350, the second support rod 310 and the third support rod 320 can be simultaneously extended or retracted. When the user needs assistance to sit up, the first support rod 200 and the second support rod 310 land simultaneously to form stable multi-point support; when movement is required, the first support rod 200 and the second support rod 310 can be retracted simultaneously to reduce contact with the ground and improve the flexibility of the cane.

[0045] Specifically, the gas spring 400 drives the first support rod 200 to extend and retract relative to the rod body 100. The movement of the first support rod 200 drives the first connecting rod 340 and the second connecting rod 350 to rotate. The two ends of the first connecting rod 340 are hinged to the first support rod 200 and the second support rod 310, respectively. The two ends of the second connecting rod 350 are hinged to the first support rod 200 and the third support rod 320, respectively. One end of the second support rod 310 is hinged to the hinge seat 330. The first connecting rod 340 is connected to the middle of the second support rod 310. One end of the third support rod 320 is hinged to the hinge seat 330, and the second connecting rod 350 is connected to the middle of the third support rod 320. When the first support rod 200 drives the first connecting rod 340 and the second connecting rod 350 to move, it can drive the second support rod 310 and the third support rod 320 to swing, so that the other end of the second support rod 310 and the other end of the third support rod 320 can be supported on the ground together with the first support rod 200. When the user gets up or sits down, it can effectively distribute the pressure and prevent tipping or slipping.

[0046] One end of the cane body 100 has a receiving groove 110. One end of the gas spring 400 is inserted into the receiving groove 110 and fixed to the groove wall. One end of the first support rod 200 is movably inserted into the receiving groove 110. By providing a receiving groove 110 at one end of the cane body 100, the connection structure between the gas spring 400 and the first support rod 200 is hidden inside the cane body 100, reducing external protrusions and making the cane more concise, portable, and easy to store and carry. Furthermore, the first support rod 200 is movably inserted into the receiving groove 110, and its extension length can be adjusted by the extension and retraction of the gas spring 400 to accommodate users of different heights and assist users in sitting up.

[0047] In this embodiment, the hinge seat 330 is fixed to the groove of the cane body 100 near the receiving groove 110, and the hinge seat 330 is sleeved on the first support rod 200, so that the connection structure of the support assembly 300, the gas spring 400, and the first support rod 200 is highly integrated, reducing redundant space occupation and making the cane more compact and lightweight. The hinge seat 330 serves as the connection hub between the support assembly 300 and the cane body 100, and also forms a linkage with the first support rod 200, simplifying the mechanical structure and reducing manufacturing complexity and cost.

[0048] The gas spring 400 includes a cylinder 410 and a piston rod 420. The cylinder 410 is fixed to the first support rod 200. One end of the piston rod 420 is placed inside the cylinder 410 and can move axially along the cylinder 410. The other end of the piston rod 420 is fixed to the cane body 100. When the user stands up or sits down, the gas spring 400 provides adjustable support force through the extension and retraction of the piston rod 420, assisting the user to complete the movement smoothly and reducing joint stress.

[0049] During the descent of the cane 100, the piston rod 420 of the gas spring 400 is compressed, which can store part of the gravitational potential energy as gas compression energy; the gas compression energy can provide power for the cane 100 to rise, thereby assisting the user in sitting down and standing up.

[0050] The cane body 100 includes a support 120, an underarm support bar 130, and a grip beam 140. The support 120 is connected to a first support bar 200. Both the underarm support bar 130 and the grip beam 140 are mounted on the support 120. A pull-wire switch 141 is mounted on the grip beam 140 and is connected to a gas spring 400. The support 120 and the first support bar 200 form a stable main support structure. The underarm support bar 130 conforms to the curve of the human armpit, distributing body weight and reducing hand pressure. The grip beam 140 provides a grip point, enhancing operational stability, and is especially suitable for users who need to use it for extended periods.

[0051] Users can directly control the extension and retraction of the gas spring 400 via the pull-cord switch 141 on the handle beam 140, enabling rapid adjustment of support force (such as assisting in standing up or sitting down) without bending over or additional operation, making it especially suitable for people with mobility impairments. The pull-cord switch 141 is positioned on the handle beam 140 to prevent users from accidentally activating other components.

[0052] The handle beam 140 is also equipped with a safety bolt 142 to limit the movement of the pull-cord switch 141. The safety bolt 142 locks the movement of the pull-cord switch 141, preventing the gas spring 400 from malfunctioning due to accidental pulling, collision, or external interference. This is especially important when the user moves or stores the cane, preventing accidental extension or retraction of the cane. In the event of a malfunction of the gas spring 400 or the pull-cord switch 141, the safety bolt 142 serves as a mechanical redundancy, ensuring the structural stability of the cane 100 and preventing the risk of falls due to sudden failure.

[0053] The underarm support bar 130 is equipped with an underarm support, which is designed to provide users with more comfortable underarm support. The shape and material of the underarm support can be optimized to distribute pressure and reduce discomfort during prolonged use; the underarm support also provides additional stability to prevent the user from slipping or losing balance when sitting down or standing up.

[0054] In this embodiment, an anti-slip pad 210 is provided at the end of the first support rod 200 away from the cane body 100. The anti-slip pad 210 is made of a material with anti-slip properties, such as rubber. A special anti-slip texture is designed on the surface of the anti-slip pad 210 to increase friction with the ground. Furthermore, the anti-slip pad 210 can be designed to be replaceable, allowing the user to easily replace it when the pad is severely worn.

[0055] The working process of the crutch for assisting sitting up provided in this embodiment is as follows:

[0056] When using the cane to assist in sitting, the user places the underarm support bar 130 under their armpit, pushes the safety latch 142 forward to activate the pull switch 141 of the gas spring 400, and then sits down. Under the influence of body weight, the gas spring 400 is compressed, causing the cane body 100 and the first support bar 200 to contract relative to each other, lowering the cane body 100. At this time, the second support bar 310 and the third support bar 320 open and can support the ground, increasing the cane's support force. After sitting down, the user releases the pull switch 141, the gas spring 400 relocks, and pushes the safety latch 142 backward to immobilize the pull switch 141.

[0057] When standing up using this cane, the user places the underarm support bar 130 under their armpit, pushes the safety latch 142 forward, and activates the pull switch 141 of the gas spring 400. This releases the energy stored in the gas spring 400, causing the cane body 100 and the first support bar 200 to extend relative to each other, allowing the cane body 100 to rise slowly and assist the user in standing. Simultaneously, the second support bar 310 and the third support bar 320 close. After standing, the user releases the pull switch 141, locking the gas spring 400. Pushing the safety latch 142 backward then immobilizes the pull switch 141.

[0058] Therefore, the cane provided in this application can assist users in sitting down and standing up. It has a simple structure, is easy to operate, and the support component 300 can provide stable support for the user, reducing the risk of falling when the user stands up or sits down.

[0059] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0060] Furthermore, the use of terms such as "first," "second," and "a" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0061] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0062] Furthermore, the technical solutions of the various embodiments of this application can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this application.
