Abstract
Description
cane chair Technical Field
[0001] This invention relates to the field of daily necessities technology, and in particular to a cane chair. Background Technology
[0002] As a type of daily necessities suitable for the elderly, cane chairs generally have two states: folded and unfolded. When folded, they can provide support for the cane; when unfolded, they can provide a place for the elderly to sit and rest.
[0003] In related technologies, such as those disclosed in patent CN114903262B, the support of the cane chair is achieved by a positioning component and two support rods. The positioning component and the two support rods are respectively inserted into the seat. In the unfolded state, the deflection angles of the two support rods relative to the main rod are inconsistent, and the forces on the two support rods are different. This difference in forces can easily lead to instability in the load-bearing capacity. Summary of the Invention
[0004] Therefore, it is necessary to provide a cane chair.
[0005] A cane chair, comprising:
[0006] A support assembly includes a base, a slider, a main rod, and two auxiliary rods. The main rod and the auxiliary rods are respectively threaded through and rotatably connected to the base, with each of the main rod and auxiliary rods extending out of the base at opposite ends. The slider is slidably engaged with the main rod and is used to switch the support assembly between a retracted state and an extended state. In the retracted state, the two auxiliary rods are close to the main rod; in the extended state, the two auxiliary rods form an angle with the main rod and are symmetrically located on opposite sides of the main rod.
[0007] The seat assembly includes a main seat and two secondary seat surfaces, which are rotatably connected to opposite sides of the main seat. The main seat is rotatably connected to the sliding member. During the process of the support assembly switching from a retracted state to an unfolded state, the sliding member drives the main seat to unfold, and the main seat drives the secondary seat to unfold. The ends of the two auxiliary rods near the seat assembly support the two secondary seat surfaces respectively. Attached Figure Description

Detailed Implementation
[0032] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.
[0033] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.
[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0035] Referring to Figures 1 and 2, this application discloses a cane chair 10, including a support assembly 100 and a seat assembly 200. The support assembly 100 includes a base 110, a slider 120, a main rod 130, and two auxiliary rods 140. Referring to Figures 3 and 4, the main rod 130 and the auxiliary rods 140 are respectively passed through and rotatably connected to the base 110, and the opposite ends of each of the main rod 130 and the auxiliary rods 140 extend out of the base 110. For example, the main rod 130 and the base 110 are connected by a pivot, and the auxiliary rods 140 and the base 110 are connected by another pivot, thus achieving a rotatable connection between the main rod 130, the auxiliary rods 140, and the base 110.
[0036] Specifically, the support 110 may include a detachably connected main body 111 and a cover plate 113. The main body 111 has three spaced-apart through holes 111a. The main rod 130 and two auxiliary rods 140 are correspondingly inserted through the three through holes 111a and rotatably connected to the main body 111. The through holes 111a provide space for the swing of the main rod 130 and auxiliary rods 140 relative to the support 110, but also limit the range of motion of the main rod 130 and auxiliary rods 140, so that the extended and retracted states of the main rod 130 and the two auxiliary rods 140 can be stably maintained. The main body 111 can be injection molded to improve molding efficiency and can have a relatively large wall thickness to improve the stability of the support. During assembly, the main rod 130 and the auxiliary rod 140 can first pass through the through hole 111a of the main body 111 and the cover plate 113. At this time, the cover plate 113 and the main body 111 can be spaced apart, exposing the internal space of the main body 111, which facilitates the assembly of the rotating shaft to the main body 111 to realize the rotatable connection between the main rod 130, the auxiliary rod 140 and the main body 111. After the main body 111 is assembled with the main rod 130 and the auxiliary rod 140, the cover plate 113 is used to cover the internal space of the main body 111. For example, the cover plate 113 is reliably fixed to the main body 111 with fasteners such as screws, so as to realize the reliable positioning of the main rod 130 and the auxiliary rod 140 on the support 110 and improve the convenience of assembly.
[0037] In some embodiments, the support 110 may include a retaining ring 115, and the cover plate 113 and the main body 111 enclose a groove 111b extending circumferentially along the main body 111. The bottom of the groove 111b is provided with a shaft hole 111c, which is used to pass through a rotating shaft 116 to achieve a rotatable connection between the main rod 130, the auxiliary rod 140 and the main body 111. Specifically, in the embodiments of this application, the main rod 130 is rotatably connected to the main body 111 through a rotating shaft 116, and the two auxiliary rods 140 share a rotating shaft 116 to achieve a rotatable connection with the main body 111, making the connection structure of the main rod 130, the auxiliary rod 140 and the main body 111 relatively simple. The retaining ring 115 is confined within the groove 111b and blocks the shaft hole 111c and the rotating shaft 116. The retaining ring 115 can be circumferentially closed and can be assembled to the main body 111 before the cover plate 113. The two protruding edges of the groove 111b in the axial direction of the main rod 130, namely one protruding edge of the main body 111 and the edge of the cover plate 113, can prevent the retaining ring 115 from easily coming off the main body 111. The retaining ring 115 can also prevent the rotating shaft 116 from easily coming off the main body 111 and serves a decorative function. During the assembly of the main rod 130, the auxiliary rod 140, and the support 110, the main rod 130 and the auxiliary rod 140 can be sequentially inserted into the through hole 111a of the main body 111, as well as the retaining ring 115 and the cover plate 113, so that the retaining ring 115 is reliably confined within the main body 111 and prevents it from easily coming off the main body 111.
[0038] The sliding member 120 can be a circumferentially closed cylindrical shape, sleeved on and slidably fitted to the main rod 130, and used to drive the support assembly 100 to switch between a retracted state and an extended state. Referring to Figures 5 and 6, in the retracted state, the two auxiliary rods 140 are joined together with the main rod 130, and the length extension direction of the auxiliary rods 140 is approximately parallel to the length extension direction of the main rod 130. Referring to Figures 1 and 2, in the extended state, the two auxiliary rods 140 form an angle with the main rod 130 and are symmetrically located on opposite sides of the main rod 130.
[0039] The seat assembly 200 may include a main seat 210 and two secondary seat 220s. The two secondary seat 220s are rotatably connected to opposite sides of the main seat 210, and the main seat 210 is rotatably connected to the slider 120. During the transition of the support assembly 100 from a retracted state to an extended state, the slider 120 causes the main seat 210 to open, and the main seat 210 causes the secondary seat 220 to open. The ends of the two auxiliary rods 140 near the seat assembly 200 support the two secondary seat 220s respectively. During the transition of the support assembly 100 from an extended state to a retracted state, the slider 120 causes the main seat 210 to retract, and the main seat 210 causes the secondary seat 220s to retract. The ends of the two auxiliary rods 140 near the seat assembly 200 can gradually detach from the two secondary seat 220s.
[0040] It is understandable that, in engineering technology, symmetry should not be regarded as a concept in a strictly geometric sense, but the existence of engineering errors should be taken into account. The fact that the two auxiliary rods 140 are asymmetrical relative to the main rod 130 within the range of engineering errors should not exclude them from the scope of protection of this application.
[0041] In some embodiments, both the main rod 130 and the auxiliary rod 140 are hollow tubular structures and can be integrally formed, i.e., the entire tube is molded as a single piece. The main rod 130 and the auxiliary rod 140 can be made of aluminum alloy to give the entire cane chair 10 a relatively light weight, making it easy for the elderly to carry, and to give the main rod 130 and the auxiliary rod 140 high structural strength to reliably support the weight of the elderly person when unfolded, ensuring safety during use.
[0042] One end of the main rod 130 may also be provided with a handle 150. The handle 150 can form a circumferentially enclosed space, making it convenient for the user to insert and grip the handle, thus facilitating the use of the cane chair 10. Furthermore, referring to Figures 5 and 6, the length of the main rod 130 can be greater than the length of the secondary rod 140. In the folded state, on the side of the support 110 away from the handle 150, the end of the main rod 130 can slightly protrude from the end of the secondary rod 140. The user can hold the handle 150 and use the end of the main rod 130 away from the handle 150 to contact the ground to support the body, thus functioning as a cane. The end of the secondary rod 140 near the handle 150 can be enclosed by the space enclosed by the main seat 210 and the secondary seat 220, which reduces the overall width of the cane chair 10, making it convenient to use as a cane, and also prevents the end of the secondary rod 140 near the handle 150 from easily detaching from the main rod 130, thus preventing inconvenience during use. Furthermore, a rubber sleeve or silicone sleeve can be installed at one end of the main rod 130 away from the handle 150. The rubber sleeve or silicone sleeve contacts the ground to reduce impact and increase the contact area, thereby improving the stability of the support and the comfort of use.
[0043] For example, referring to Figures 5 and 6, one of the two secondary seat surfaces 220 may also be provided with a locking block 221, and the other with a locking slot 220a. In the folded state, the locking block 221 engages with the locking slot 220a, so that the main seat surface 210 and the secondary seat surface 220 form a rectangular box-shaped space, and the end of the folded secondary rod 140 near the seat surface assembly 200 is stored in the space formed by the main seat surface 210 and the secondary seat surface 220. This structure can stably maintain the folded state of the cane chair 10, preventing the support assembly 100 and the seat surface assembly 200 from easily opening when the user uses the cane chair 10 as a cane. Of course, in other embodiments, magnetic attraction, Velcro, or other methods can also be used to achieve the engagement of the two secondary seat surfaces 220, so that the folded state of the cane chair 10 can be stably maintained.
[0044] Referring to Figures 7 and 8, in the unfolded state, the two auxiliary rods 140 are cross-shaped at the support 110. A pin 141 can be provided at the cross-shaped position of the two auxiliary rods 140 to achieve a rotatable connection. Furthermore, the two auxiliary rods 140 can have opposing notches 140a, which allow for mutual insertion, making their rotation more stable and limiting the rotation range. Further, referring to Figure 8, a torsion spring 143 can be fitted onto the pin 141. The two free ends of the torsion spring 143 abut against the two auxiliary rods 140 respectively, causing the two auxiliary rods 140 to tend to spread apart, making it easier for the cane chair 10 in the folded state to unfold.
[0045] Further, referring to Figure 7, in the unfolded state, the two auxiliary rods 140 form an upper included angle space 140b and a lower included angle space 140c, with the main rod 130 passing through one of the upper included angle space 140b and the lower included angle space 140c. Taking the main rod 130 passing through the lower included angle space 140c as shown in Figure 7 as an example, since the main rod 130 and the auxiliary rod 140 are rotatably connected to the support 110, the position of the support 110 relative to the main rod 130 in the axial direction remains basically unchanged. The rotation of the auxiliary rod 140 relative to the support 110 causes it to swing relative to the main rod 130. The auxiliary rod 140 can have a suitable relative movement space with the support 110 in the axial direction, so as to facilitate the switching of the support assembly 100 between the retracted state and the unfolded state. In the unfolded state, the two auxiliary rods 140 form an angle with the main rod 130 and are symmetrically located on opposite sides of the main rod 130. The triangle formed by the line connecting the end of the main rod 130 away from the handle 150 and the end of the two auxiliary rods 140 away from the handle 150 can be an isosceles triangle. When the user sits on the unfolded seat assembly 200, the two auxiliary rods 140 on both sides of the main rod 130 are subjected to equal forces, that is, the forces on the two auxiliary rods 140 are relatively balanced. The center of gravity supporting the user can fall within the axis of symmetry of the isosceles triangle, i.e., the projection of the main rod 130, forming a stable support structure. This prevents the force on one auxiliary rod 140 from being significantly greater than that on the other auxiliary rod 140, which would cause instability in the support. This ensures the stability of the support and improves the safety performance during use. Furthermore, after the user sits on the unfolded seat assembly 200, since the main rod 130 is located in the lower angled space 140c, the intersection of the two auxiliary rods 140 tends to approach the main rod 130, and the main rod 130 at the support 110 also tends to approach the intersection of the auxiliary rods 140. The main rod 130 is usually larger in size, such as width and wall thickness, than the auxiliary rods 140, and has a stronger load-bearing capacity. The compressive force generated by this tendency to approach each other can be borne by the support 110 and the main rod 130, forming a stable spatial triangle, providing stable support for the user, preventing the unfolded support assembly 100 from easily tipping over, and improving the safety and comfort of use.
[0046] Referring again to Figures 7 and 8, and in conjunction with Figure 9, the support assembly 100 may include a first connecting rod 160 and two second connecting rods 170. One end of the first connecting rod 160 is rotatably connected to the main rod 130, and the other end of the first connecting rod 160 is connected to the main seat 210. The connection position between the first connecting rod 160 and the main seat 210 is spaced apart from the connection position between the main seat 210 and the slider 120. In the folded state, the first connecting rod 160 and the two second connecting rods 170 are also housed within the space formed by the main seat 210 and the secondary seat 220, making the structure of the cane chair 10 more compact in the folded state and avoiding excessive width that would reduce ease of use. The connection position between the first connecting rod 160 and the main rod 130 is located between the slider 120 and the support 110. One end of each of the two second connecting rods 170 is rotatably connected to the slider 120, and the other ends of the two second connecting rods 170 are rotatably connected to two auxiliary rods 140 respectively. Each auxiliary rod 140 has a support end 145 that supports the secondary seat surface 220 when in the unfolded state. The connection point between the second connecting rods 170 and the auxiliary rods 140 is located between the support 110 and the support end 145. The connection point between the second connecting rod 170 and the slider 120 is located between the connection point between the slider 120 and the main seat surface 210, and the connection point between the first connecting rod 160 and the main rod 130. In other words, the connection points between the slider 120 and the main seat surface 210, the second connecting rod 170 and the slider 120, the first connecting rod 160 and the main rod 130, and the support 110 are arranged sequentially along the axial extension direction of the main rod 130.
[0047] Referring to Figures 6, 9, and 10, when the sliding member 120 is in the retracted state, it is closer to the handle 150 than when it is in the extended state. During the transition of the support assembly 100 from the retracted state to the extended state, the sliding member 120 slides along the main rod 130 toward the support 110. The second connecting rod 170 pushes the end of the secondary rod 140 near the seat assembly 200 away from the main rod 130. The supporting end 145 of the secondary rod 140 can abut against the secondary seat 220, causing the free end of the secondary seat 220 to gradually move away from the support 110. Consequently, the free end of the main seat 210 gradually moves away from the support 110. The main seat 210 drives the first connecting rod 160 to swing relative to the main rod 130, and the first connecting rod 160 swings relative to the main seat 210 until it supports the main seat 210 in the extended state (Figure 2).
[0048] Further, referring to Figure 11, the first link 160 includes a swing arm 161 rotatably connected to the main seat surface 210, and a support rod 163 rotatably connected to the swing arm 161. The support rod 163 is rotatably connected to the main rod 130. The main seat surface 210 is provided with a limiting groove 210a for limiting the rotation range of the swing arm 161. During the switching between the folded and unfolded states of the support assembly 100, the swing arm 161 drives the support rod 163 to swing relative to the main seat surface 210. During the switching between the folded and unfolded states of the support assembly 100, i.e., as the free ends of the secondary seat 220 and the main seat 210 move closer to and further away from the main rod 130, the distances between the connection points (first and second) of the swing arm 161 and the main seat 210, and between the support rod 163 and the main rod 130, change. Using a fixed-length first connecting rod 160 would hinder the opening of the main seat 210. The swing arm 161 and support rod 163, however, form a movable joint, as shown in Figure 9, adapting to the changing distances between the first and second connection points and accommodating the folding and unfolding movements of the main seat 210, making the folding and unfolding of the main seat 210 smoother. In the unfolded state, the swing arm 161 and support rod 163 work together to support the main seat 210, providing stable support for the seat assembly 200 in the unfolded state. Of course, it is understandable that the swing arm 161 of the first link 160 can be omitted, and the two ends of the support rod 163 can be rotatably connected to the main rod 130 and the main seat 210 respectively. That is, the first link 160 can also open the main seat 210 by means of a single rod combined with the user's auxiliary operation.
[0049] Referring to Figures 12, 13, and 14, in some embodiments, the cane chair 10 may include an auxiliary assembly 300, which includes a first swing arm 310 and a second swing arm 320 rotatably connected to the main seat surface 210. A slider 120 has a protrusion 121, and two secondary seat surfaces 220 each have abutment portions 223. In the unfolded state, the first swing arm 310, the second swing arm 320, and the abutment portions 223 are all located on the side of the seat assembly 200 opposite to the support surface (i.e., the surface used to support the user's body in the unfolded state), so that the main seat surface 210 and the secondary seat surfaces 220 can conceal the first swing arm 310, the second swing arm 320, and the abutment portions 223 in both the unfolded and folded states, resulting in a simpler appearance for the cane chair 10.
[0050] Figure 12 shows the relative positions of the first swing arm 310, the second swing arm 320, the main seat surface 210, and the secondary seat surface 220 when the support assembly 100 is in the folded state; Figure 13 shows the relative positions of the first swing arm 310, the second swing arm 320, the main seat surface 210, and the secondary seat surface 220 at a certain position between the folded and unfolded states; and in conjunction with Figure 15, Figure 15 shows the relative positions of the first swing arm 310, the second swing arm 320, the main seat surface 210, and the secondary seat surface 220 when the support assembly 100 is in the unfolded state.
[0051] During the transition of the support assembly 100 from the retracted state to the extended state, the protrusion 121 presses against the first swing arm 310 and the second swing arm 320 and drives the first swing arm 310 and the second swing arm 320 to rotate relative to the main seat surface 210. The first swing arm 310 presses against the abutment part 223 on one side, and the second swing arm 320 presses against the abutment part 223 on the other side, so that the two sub-seat surfaces 220 are spread apart relative to the main seat surface 210. When the chair is closed, the main seat 210, secondary seat 220, main rod 130, and secondary rod 140 can be considered roughly parallel. During the initial unfolding phase, as the slider 120 slides along the main rod 130 towards the support 110, it is relatively difficult to open the secondary seat 220 using the lateral force of the support end 145 of the secondary rod 140. Often, it is necessary to first pull the free end of the main seat 210 away from the main rod 130 by hand to successfully overcome this initial unfolding phase. However, since the user typically holds the main rod 130 or handle 150 with one hand and pushes the slider 120 with the other, it is difficult to simultaneously manage the main seat 210, potentially causing an unsmooth opening. The auxiliary component 300 assists in opening the secondary seat 220 relative to the main seat 210, improving the smoothness of the seat assembly 200's opening and thus enhancing ease of use.
[0052] Specifically, referring to Figures 13 and 14, the auxiliary component 300 may include a return member 330 connected to the main seat 210. The return member 330 is connected to at least one of the first swing arm 310 and the second swing arm 320. During the transition of the support component 100 from the extended state to the retracted state, the return member 330 drives the first swing arm 310 and the second swing arm 320 to reset, thus returning the first swing arm 310 and the second swing arm 320 to their initial positions to facilitate the next unfolding of the seat component 200. The return member 330 is not limited to a spring or torsion spring, but may also be a structure such as an elastic column. Taking the spring shown in Figure 14 as an example, the spring can be in a naturally unstretched state when it is in the folded state. During the process when the protrusion 121 of the slider 120 drives the first swing arm 310 and the second swing arm 320 to swing relative to the main seat surface 210, that is, during the process of the support assembly 100 switching from the folded state to the unfolded state, the spring is stretched and accumulates elastic force, so that the first swing arm 310 and the second swing arm 320 tend to return to the initial position. During the process of the support assembly 100 switching from the unfolded state to the folded state, the spring can release elastic potential energy and drive the first swing arm 310 and the second swing arm 320 to return to the initial position.
[0053] In particular, in some embodiments, the first swing arm 310 and the second swing arm 320 can be meshed with each other through incomplete gears to achieve synchronous swinging relative to the main seat 210, thereby achieving synchronous movement of the two secondary seat surfaces 220 and improving the convenience of use.
[0054] The structure and working principle of the first swing arm 310 and the second swing arm 320 are similar, and the first swing arm 310 will be used as an example for explanation here. Referring to Figure 14, the first swing arm 310 includes an integrally formed body 311 and a support part 313. The body 311 is generally rectangular in shape, and the support part 313 is connected to one end of the body 311 and is inclined to the length extension direction of the body 311. The opposite end of the body 311 has a guide surface 3111, which is planar and inclined to the length direction of the body 311. The body 311 is rotatably connected to the main seat surface 210. For example, the main seat surface 210 is provided with a rotation axis perpendicular to its support surface (i.e., the surface used to support the user's body when unfolded), and the body 311 is provided with a hole that rotatably engages with the rotation axis. During the transition of the support assembly 100 from a retracted state to an extended state, the protrusion 121 presses against the bearing portion 313 and drives the main body 311 to rotate relative to the main seat surface 210. The guide surface 3111 presses against the abutment portion 223 corresponding to the first swing arm 310, thereby driving the corresponding secondary seat surface 220 to rotate relative to the main seat surface 210. In some embodiments, the abutment portion 223 has a plane adapted to the guide surface 3111. For example, the guide surface 3111 is inclined at 45-60 degrees relative to the length direction of the main body 311, and the adapting plane of the abutment portion 223 is inclined at an angle that is substantially equal to the width direction of the secondary seat surface 220. This allows the guide surface 3111 to fit against the adapting plane when the support assembly 100 is fully extended, keeping the surfaces of the main seat surface 210 and the secondary seat surface 220 that come into contact with the user's body in a relatively flat state.
[0055] Furthermore, referring to Figure 15, the first swing arm 310 may also include a limiting part 315 integrally formed with the body 311. The limiting part 315 protrudes from the guide surface 3111 along the length extension direction of the body 311. During the process of the protrusion 121 pressing against the bearing part 313, the protrusion 121 restricts the range of motion of the body 311 to prevent the first swing arm 310 from having an excessive range of motion, which would cause the support of the sub-seat surface 220 to fail.
[0056] Referring to Figures 16 and 17, in some embodiments, the cane chair 10 may further include an elastic member 180 disposed within the main rod 130. One end of the elastic member 180 is connected to a sliding member 120, and the opposite end of the elastic member 180 is connected to the main rod 130. The elastic deformation of the elastic member 180 in the retracted state (Figure 16) is greater than that in the extended state (Figure 17), so that the sliding member 120 is driven to slide along the main rod 130 in the retracted state, thereby switching to the extended state. Referring to Figure 17, the main rod 130 may have a through groove 130a. The sliding member 120 includes a sleeve 123 and a connecting pin 125 connected to the sleeve 123, and a protrusion 121 is integrally formed on the sleeve 123. The sleeve 123 is slidably fitted onto the main rod 130. The second connecting rod 170 and the main seat surface 210 are rotatably connected to the sleeve 123. The connecting pin 125 passes through the through groove 130a. The two ends of the connecting pin 125 can be riveted to a structure wider than the through groove 130a to prevent the connecting pin 125 from coming out of the through groove 130a. One end of the elastic element 180 is connected to the connecting pin 125, and the other end is connected to the main rod 130. As the sleeve 123 slides along the main rod 130, the connecting pin 125 slides along the through groove 130a, thereby realizing the elastic extension and retraction of the elastic element 180. Of course, it is understood that the elastic element 180 and the associated through groove 130a and connecting pin 125 can be omitted. In the default state, the user can also switch between the unfolded and retracted states through manual operation.
[0057] Furthermore, the cane chair 10 may include a locking structure 190 movably connected to the handle 150. In the folded state, the locking structure 190 locks the sliding member 120 to the main rod 130; the locking structure 190 can also release the lock on the sliding member 120 to switch to the unfolded state. Specifically, the locking structure 190 includes a button 191 and a retaining member 193 movably connected to the handle 150. The retaining member 193 has a protruding retaining portion 1931 at one end near the support 110. Referring to Figures 18 and 19, the main rod 130 has a first locking hole 130b, and the sliding member 120 has a second locking hole 120a. In the folded state, the first locking hole 130b and the second locking hole 120a communicate to allow the retaining portion 1931 to pass through, thereby locking the sliding member 120 to the main rod 130. When the user presses button 191, the retaining part 1931 is driven out of the second locking hole 120a, thereby releasing the lock on the slider 120. In other words, in the folded state, by using the retaining part 1931 passing through the first locking hole 130b and the second locking hole 120a, the slider 120 can be locked to the main rod 130, so that the support assembly 100 is stably kept in the folded state, thereby realizing the cane function.
[0058] In some embodiments, the locking structure 190 may further include a reset member 195 that abuts against the main rod 130 and the retaining member 193. After the second retaining hole 120a moves from a misaligned state to an aligned state relative to the first retaining hole 130b, the reset member 195 drives the retaining part 1931 to pass through the second retaining hole 120a, thereby achieving automatic engagement between the retaining part 1931 and the sliding member 120. The reset member 195 is not limited to a spring, but may also be a spring sheet or an elastic post, etc. In some embodiments, the reset member 195 is provided corresponding to the button 191 and can also be used to reset the button 191.
[0059] When the user needs to use the cane chair 10 as a seat, after unlocking the two secondary seat surfaces 220, press the button 191. The button 191 drives the retaining part 1931 to exit the second locking hole 120a. Under the pulling force of the elastic member 180, the sliding member 120 automatically slides down along the main rod 130. The two second connecting rods 170, through the two secondary rods 140, push the free ends of the two secondary seat surfaces 220 and the free ends of the main seat surface 210 connected to the secondary seat surfaces 220 away from the main rod 130. The auxiliary component 300 drives the two secondary seat surfaces 220 to open relative to the main seat surface 210. The main seat surface 210, through the swing rod 161, drives the support rod 163 to swing relative to the main rod 130 to support the main seat surface 210, until the seat surface assembly 200 is opened to the unfolded state. Of course, it is understandable that the locking structure 190 can be omitted. When the locking structure 190 is omitted or fails, the user can manually switch between the folded and unfolded states.
[0060] Referring again to Figure 17, in some embodiments, the support rod 163 can be rotatably connected to the main rod 130 via a limiting sleeve 135. For example, the limiting sleeve 135 is fitted onto the main rod 130 and its position is fixed relative to the main rod 130. The width of the limiting sleeve 135 is greater than the width of the main rod 130, and the inner hole width of the slider 120 is smaller than the width of the limiting sleeve 135. During the sliding of the slider 120 down the main rod 130, the slider 120 can abut against the limiting sleeve 135, thereby limiting the sliding range of the slider 120 down the main rod 130. The handle 150 and the locking structure 190 can limit the sliding range of the slider 120 up the main rod 130. For example, when the slider 120 slides down the main rod 130 to abut against the limiting sleeve 135, the support assembly 100 reaches the unfolded state; when the slider 120 slides up the main rod 130 to lock with the locking structure 190, the support assembly 100 reaches the retracted state.
[0061] When the user needs to fold up the support component 100, that is, to switch the support component 100 from the unfolded state to the folded state, he can hold the slider 120 and pull it up along the main rod 130, so that the connection position between the second link 170 and the slider 120 moves up along the main rod 130 until the second locking hole 120a of the slider 120 engages with the locking part 1931 of the locking structure 190, so that the support component 100 reaches the folded state. During this process, the slider 120 pulls the ends of the two auxiliary rods 140 near the seat assembly 200 (i.e., the support end 145) towards the main rod 130, and the squeezing effect of the protrusion 121 on the slider 120 on the first swing arm 310 and the second swing arm 320 decreases. The free end of the main seat 210 gradually moves closer to the main rod 130, and the swing rod 161 drives the end of the support rod 163 away from the main rod 130 to gradually move closer to the main rod 130 on the side near the handle 150. Under the action of the return member 330, the first swing arm 310 and the second swing arm 320 relative to the main seat... 210 rotates and gradually returns to its initial position, and the supporting force of the secondary rod 140 on the secondary seat surface 220 gradually decreases. Under the action of gravity, the two secondary seat surfaces 220 will rotate relative to the main seat surface 210 and move closer to the main rod 130. The elastic element 180 connected to the main rod 130 and the sliding member 120 inside the main rod 130 is stretched and accumulates elastic potential energy, so that the sliding member 120 and the locking part 1931 are reliably engaged, so that the support component 100 is stably kept in the folded state. The user can then fasten the two secondary seat surfaces 220 together, so that the seat component 200 is also stably kept in the folded state.
[0062] Further referring to Figure 16, and in conjunction with Figures 1 and 7, in some embodiments, the slider 120 has hanging holes 120b on opposite sides in the length extension direction perpendicular to the main rod 130. The hanging holes 120b are used to connect a hanging rope 197 or to hang other items. In this embodiment, the hanging hole 120b is located at the end of the slider 120 furthest from the support 110 and is connected to a hanging rope 197. When the support assembly 100 is in the extended state, the user can pull the slider 120 upwards using the hanging rope 197 to improve ease of use. Of course, when the support assembly 100 is in the retracted state, the hanging rope 197 can be used to hang the cane chair 10 on a hook or in another location for easy placement by the user.
[0063] Referring again to Figures 18 and 19, in some embodiments, the handle 150 may include a grip portion 151, an adjusting sleeve 153 connected to the grip portion 151, and an adjusting member 155 detachably connected to the adjusting sleeve 153. The main rod 130 passes through the adjusting sleeve 153 and has at least two first adjusting holes 130c spaced apart along the axial direction of the main rod 130. The adjusting sleeve 153 has a second adjusting hole 153a. The adjusting member 155 passes through the second adjusting hole 153a and one of the first adjusting holes 130c, thereby fixing the relative positions of the main rod 130 and the handle 150. After the adjusting member 155 is detached from the second adjusting hole 153a, the grip portion 151 can move the adjusting sleeve 153 relative to the main rod 130, so that the second adjusting hole 153a aligns with any of the remaining first adjusting holes 130c, for inserting the adjusting member 155 and adjusting the relative positions of the grip portion 151 and the main rod 130. The adjusting component 155 can be a bolt or a similar threaded part, which can be inserted into the first adjusting hole 130c and the second adjusting hole 153a to limit the handle 150 in the axial direction of the main rod 130. This makes the distance between the grip 151 and the end of the main rod 130 away from the handle 150 adjustable, so that the overall length of the main rod 130 and the handle 150 can be adjusted to accommodate people of different heights and improve the comfort and convenience of use.
[0064] Specifically, the adjusting sleeve 153 may include an inner cylinder 1531 connected to the grip portion 151 and an outer cylinder 1533 connected to the grip portion 151 and fitted with the inner cylinder 1531. The adjusting member 155 is detachably connected to the outer cylinder 1533 and the inner cylinder 1531. One end of the main rod 130 near the handle 150 passes through the inner cylinder 1531 and the outer cylinder 1533. The outer cylinder 1533 has a second adjusting hole 153a. The inner cylinder 1531 has an auxiliary hole 153b aligned with the second adjusting hole 153a. The adjusting member 155 passes through the auxiliary hole 153b, the second adjusting hole 153a and one of the first adjusting holes 130c, so that the positions of the main rod 130 and the handle 150 are relatively fixed. The structure in which the adjusting member 155 passes through the auxiliary hole 153b and the second adjusting hole 153a allows the adjusting member 155 to be supported by the hole walls of the auxiliary hole 153b and the second adjusting hole 153a, forming a more stable support structure and improving the limiting stability and reliability of the adjusting sleeve 153 on the main rod 130.
[0065] Since the positions of the inner cylinder 1531 and the outer cylinder 1533 relative to the main rod 130 are adjustable, in some embodiments, the button 191 of the locking structure 190 is located on the outer cylinder 1533 and remains unchanged in the axial position of the outer cylinder 1533. The locking member 193 of the locking structure 190 is connected to the grip portion 151 and can swing slightly relative to the grip portion 151 to exit or enter the second locking hole 120a of the slider 120. The first locking hole 130b on the main rod 130 can extend along the axial direction of the main rod 130 in a narrow groove-shaped structure. When the main rod 130 moves axially relative to the handle 150, the locking member 1931 moves along the narrow first locking hole 130b and remains in the first locking hole 130b, ensuring that the locking structure 190 can lock the slider 120 in time.
[0066] Referring to Figures 20 and 21, in some embodiments, the handle 150 may further include a hook 157 connected to the grip portion 151. The grip portion 151 has a receiving groove 151a, and a rotating post 158 is provided at the bottom of the receiving groove 151a. The rotating post 158 may be integrally formed with the grip portion 151. One end of the hook 157 has an opening 157a for inserting the rotating post 158 and an oblong hole 157b communicating with the opening 157a. The width of the opening 157a may be smaller than the diameter of the rotating post 158. During the assembly of the hook 157 and the grip portion 151, the hook 157 passes over the rotating post 158 through the deformation of the opening 157a, reliably confining the rotating post 158 within the oblong hole 157b. The hook 157 has a engaged state and an open state relative to the gripping part 151. In the engaged state, the hook 157 is engaged in the receiving groove 151a and the rotating post 158 abuts against one end of the oblong hole 157b, as shown in Figure 20. In the open state, the end of the hook 157 away from the rotating post 158 disengages from the gripping part 151 and forms a suspension space with the gripping part 151, while the rotating post 158 abuts against the opposite end of the oblong hole 157b, as shown in Figure 21. The engagement of the waist-shaped hole 157b with the rotating column 158 allows the hook 157 to be suspended from the rotating column 158 through one end of the hole wall of the waist-shaped hole 157b when it is in the open state. This allows the hook 157 and the grip part 151 to reliably suspend the entire cane chair 10 on a wall or other location. When switching the hook 157 from the open state to the closed state, the user needs to push the free end of the hook 157 into the receiving groove 151a and simultaneously drive the end of the hook 157 with the waist-shaped hole 157b to move away from the support 110. Combined with the engagement structure of the free end of the hook 157 and the engagement of the receiving groove 151a, the hook 157 can be stably engaged in the receiving groove 151a, preventing the hook 157 from easily coming out of the receiving groove 151a.
[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0068] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
