Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and in particular to a cane chair and its support. 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 through the seat and rotatably connected to the seat. That is, three rotating shafts are set to achieve the rotatable connection between the positioning component, the support rods and the seat, which is a relatively complex structure. Utility Model Content

[0004] This utility model provides a cane chair and its support to simplify the structure of the cane chair's support.

[0005] A support has three spaced-apart through holes for correspondingly threading the main rod and two auxiliary rods of a cane chair; the support has circumferential holes for threading a pivot, and the main rod and the auxiliary rods are rotatably connected to the support via the pivot, with the two auxiliary rods sharing a single pivot.

[0006] In one embodiment, the support includes a carrier and a retaining ring confined within the carrier, the carrier having a circumferentially extending groove, the shaft hole being formed at the bottom of the groove, and the retaining ring confined within the groove and covering the shaft hole.

[0007] In one embodiment, the carrier includes a body and a cover plate detachably connected to the body, the through hole extending from the body to the cover plate, the cover plate and the body enclosing the groove extending circumferentially along the body.

[0008] In one embodiment, the body has a groove bottom extending circumferentially and a flange protruding from one end of the groove bottom and extending circumferentially along the body. The circumferential edge of the cover plate protrudes from the groove bottom and surrounds the groove bottom and the flange to form the groove. The circumferential edge of the cover plate and the flange abut against the opposite ends of the retaining ring in a corresponding manner along the axial direction of the support.

[0009] In one embodiment, the main body includes a mounting portion and a connecting portion. The mounting portion has the groove bottom, the flange, and the shaft hole. The cover plate is detachably connected to one end of the mounting portion, and the connecting portion is detachably connected to the end of the mounting portion opposite to the groove bottom. The connecting portion and the mounting portion enclose each other to form two spaced-apart first through holes for the auxiliary rod to pass through. The mounting portion has a second through hole for the main rod to pass through.

[0010] In one embodiment, the mounting portion has a protrusion disposed away from the second through hole and a slot disposed adjacent to the flange, the connecting portion has a recess corresponding to the protrusion and accommodating the protrusion, and a protrusion corresponding to the slot and inserted into the slot.

[0011] In one embodiment, the retaining ring is in the shape of a circumferentially closed ring.

[0012] A cane chair includes a seat assembly, a slider, a main rod, two auxiliary rods, and a support as described above. Each of the main rod and auxiliary rods extends from opposite ends of the support. The slider is slidably engaged with the main rod and rotatably connected to the seat assembly to switch the seat assembly between a closed state and an open state. In the closed state, the two auxiliary rods are joined to the main rod. In the open state, the two auxiliary rods form an angle with the main rod, and the ends of the two auxiliary rods closest to the seat assembly support the seat assembly.

[0013] In one embodiment, the seat assembly includes a main seat and two secondary seat surfaces, the two secondary seat surfaces being rotatably connected to opposite sides of the main seat, and the main seat being rotatably connected to the sliding member; the sliding member can drive the main seat to open, the main seat causing the secondary seat surfaces to open, and in the open state, the ends of the two auxiliary rods near the seat assembly support the two secondary seat surfaces respectively.

[0014] In one embodiment, the cane chair includes an elastic element disposed within the main rod, a handle connected to the end of the main rod away from the support, and a locking structure movably connected to the handle. One end of the elastic element is connected to the sliding element, and the opposite end of the elastic element is connected to the main rod. The elastic deformation of the elastic element in the closed state is greater than the elastic deformation in the open state. When the locking structure is in the closed state, it locks the sliding element to the main rod. The locking structure can also release the locking of the sliding element, so that the sliding element can be driven by the elastic element to slide along the main rod, thereby switching to the open state.

[0015] The above-mentioned support can be used in a cane chair. The support includes a load-bearing component and a retaining ring. The load-bearing component has three spaced-apart through holes for the main rod and two auxiliary rods of the cane chair to pass through, one-to-one. The load-bearing component also has circumferential holes for axles to pass through. The main rod and auxiliary rods are rotatably connected to the load-bearing component via axles, with the two auxiliary rods sharing a single axle. Compared to a scheme where the main rod and two auxiliary rods each have a corresponding axle (i.e., three axles), the two auxiliary rods in this application share a single axle, resulting in a simpler connection structure between the support and the main and auxiliary rods.

Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0038] refer to Figure 1 and Figure 2 This application discloses a cane chair 10, which includes a support assembly 100 and a seat assembly 200. The support assembly 100 includes a support 110, a slider 120, a main rod 130, and two auxiliary rods 140, combined with... Figure 3 and Figure 4 The main rod 130 and the auxiliary rod 140 are respectively inserted through and rotatably connected to the support 110, with each of the main rod 130 and the auxiliary rod 140 extending out of the support 110 at opposite ends. The sliding member 120 is slidably engaged with the main rod 130 and rotatably connected to the chair seat assembly 200, thereby switching the chair seat assembly 200 between a closed state and an open state. In the closed state, the two auxiliary rods 140 are joined together with the main rod 130, as shown... Figure 5 As shown; in the open state, the two auxiliary rods 140 form angles with the main rod 130, and the ends of the two auxiliary rods 140 near the seat assembly 200 support the seat assembly 200, as shown. Figure 1 and Figure 2 As shown.

[0039] Specifically, in combination Figure 6 , Figure 7 and Figure 8The support 110 may include a carrier 111 and a retaining ring 113. The carrier 111 has three spaced-apart through holes 111a, which are used to pass through the main rod 130 and two auxiliary rods 140 of the cane chair 10, one to one. The carrier 111 has a circumferentially oriented shaft hole 111b for a pivot 116 to pass through. The main rod 130 is rotatably connected to the carrier 111 via a pivot 116, and the two auxiliary rods 140 share another pivot 116 to be rotatably connected to the carrier 111. The retaining ring 113 is located on the carrier 111 and blocks the shaft hole 111b. In some embodiments, the retaining ring 113 is a circumferentially closed ring, which has a decorative function and can prevent the pivot 116 from easily coming off the support 110. The retaining ring 113 can be made of metal, such as stainless steel, or non-metal, such as plastic.

[0040] Furthermore, the support member 111 has a circumferentially extending groove 111c, the diameter of which is approximately equal to the inner diameter of the retaining ring 113. A shaft hole 111b is formed at the bottom of the groove 111c, and the retaining ring 113 is confined within the groove 111c to reliably confine the retaining ring 113 to the support 110, preventing the retaining ring 113 from easily disengaging from the support 110.

[0041] Specifically, the support member 111 may include a detachably connected body 1111 and a cover plate 1113. The through hole 111a extends from the body 1111 to the cover plate 1113. The body 1111 may have a groove bottom 11111 extending circumferentially, and a flange 11113 protruding from one end of the groove bottom 11111 and extending circumferentially along the body 1111. The circumferential edge of the cover plate 1113 protrudes from the groove bottom 11111 and surrounds the groove bottom 11111 and the flange 11113 to form a groove 111c. The circumferential edge of the cover plate 1113 and the flange 11113 abut against the opposite ends of the retaining ring 113 along the axial direction of the support 110, thereby reliably confining the retaining ring 113 in the body 111.

[0042] Furthermore, combined with Figure 7 , Figure 8 and Figure 9 The main body 1111 may include a mounting portion 11115 and a connecting portion 11117. The mounting portion 11115 may be injection molded and has a groove bottom 11111, a flange 11113, and a shaft hole 111b. The cover plate 1113 is detachably connected to one end of the mounting portion 11115, and the connecting portion 11117 is detachably connected to one end of the mounting portion 11115 opposite to the groove bottom 11111, and together with the mounting portion 11115, forms two spaced-apart first through holes 111a1 for through which the auxiliary rod 140 passes. Figure 6The mounting part 11115 has a second through hole 111a3 for the main rod 130 to pass through. This structure of the support 110 facilitates processing and assembly. The first through hole 111a1 provides space for the secondary rod 140 to swing relative to the support 110 while limiting its range of motion. The second through hole 111a3 provides space for the main rod 130 to swing relative to the support 110 while limiting its range of motion, ensuring that the main rod 130 and the two secondary rods 140 are stably maintained in both the open and closed states of the seat assembly 200. The main body 1111 can have a relatively large wall thickness to improve the stability of the support.

[0043] Combination Figure 10 and Figure 11 During assembly, the two auxiliary rods 140 can be cross-assembled and passed through the connecting part 11117, and then passed through the mounting part 11115, the retaining ring 113 and the cover plate 1113 respectively with the main rod 130. At this time, the cover plate 1113, the retaining ring 113 and the mounting part 11115 of the main body 1111 can be spaced apart to expose the internal space of the mounting part 11115, so as to facilitate the assembly of the rotating shaft 116 to the main body 1111 to realize the rotational connection between the main rod 130, the auxiliary rod 140 and the main body 1111. After the mounting part 11115 is assembled with the main rod 130 and the auxiliary rod 140, the connecting part 11117 is fixedly connected to the mounting part 11115. The retaining ring 113 is moved to the groove 111c position, and the cover plate 1113 is used to cover the internal space of the mounting part 11115. For example, the cover plate 1113 is reliably fixed to the mounting part 11115 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.

[0044] Continue to refer to Figure 7 and Figure 8 The mounting portion 11115 has a protrusion a11 disposed away from the second through hole 111a3 and a slot a13 disposed adjacent to the flange 11113. The connecting portion 11117 has a concave hole b11 corresponding to the protrusion a11 and accommodating the protrusion a11, and a protrusion b13 corresponding to the slot a13 and inserted into the slot a13. After the two cross-assembled auxiliary rods 140 are respectively inserted into the connecting part 11117 and the mounting part 11115, the protrusion b13 of the connecting part 11117 can be inserted into the slot a13 of the mounting part 11115, and the protrusion a11 of the mounting part 11115 can be aligned and inserted into the concave hole b11 of the connecting part 11117, so as to achieve the initial positioning of the connecting part 11117 in the mounting part 11115. Then, the connecting part 11117 and the mounting part 11115 can be reliably fixed by fasteners such as screws or bolts. While improving the assembly convenience of the main rod 130, auxiliary rod 140 and support 110, the connection reliability of the connecting part 11117 in the mounting part 11115 is guaranteed, and the two are prevented from loosening due to the frequent swinging of the main rod 130 and auxiliary rod 140.

[0045] The support 110 includes a bearing member 111 and a retaining ring 113. The bearing member 111 has three spaced through holes 111a, which are used to pass through the main rod 130 and two auxiliary rods 140 of the cane chair 10, one by one. The bearing member 111 has a circumferential hole 111b for passing through a pivot 116. The main rod 130 and the auxiliary rods 140 are rotatably connected to the bearing member 111 via pivots 116, and the two auxiliary rods 140 share a pivot 116. Compared with the scheme where the main rod 130 and the two auxiliary rods 140 are provided with pivots 116 one by one, i.e., three pivots 116 are provided, the connection structure between the support 110 and the main rod 130 and the auxiliary rods 140 is simpler because the two auxiliary rods 140 share a pivot 116. The retaining ring 113 is positioned on the support member 111 and blocks the shaft hole 111b, which makes the support 110 more aesthetically pleasing and prevents the rotating shaft 116 from easily coming off the support member 111.

[0046] 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. Figure 5 In the folded 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. At this time, the chair seat assembly 200 is in the closed state. (Reference) Figure 1 and Figure 2 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, at which time the seat assembly 200 is in the open state.

[0047] 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 may gradually detach from the two secondary seat 220s until they are joined to the main rod 130.

[0048] 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.

[0049] 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.

[0050] One end of the main rod 130 may also be equipped with a handle 150. The handle 150 can form a circumferentially enclosed space, allowing the user to easily insert and grip the handle, thus facilitating the use of the cane chair 10. Furthermore, combined with... Figure 5 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 beyond the end of the secondary rod 140. The user can grip the handle 150 and use the end of the main rod 130 away from the handle 150 to contact the ground for body support, functioning as a cane. The end of the secondary rod 140 near the handle 150 can be enclosed by the space between the main seat 210 and the secondary seat 220, reducing the overall width of the cane chair 10 for easier use as a cane and preventing the end of the secondary rod 140 near the handle 150 from easily detaching from the main rod 130 and causing inconvenience. Furthermore, the end of the main rod 130 away from the handle 150 can be fitted with a rubber or silicone sleeve, which, by contacting the ground, reduces impact and increases the contact area, improving support stability and user comfort.

[0051] Further, refer to Figure 10 and Figure 11 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. Figure 10 Taking the example of the main rod 130 passing through the lower included angle space 140c, since the main rod 130 and the secondary 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 secondary rod 140 relative to the support 110 causes it to swing relative to the main rod 130. The secondary 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 extended state.

[0052] 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.

[0053] 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.

[0054] Combined Figure 10 , Figure 11 and Figure 12 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 process of the support assembly 100 switching from the retracted state to the extended state, the sliding member 120 slides along the main rod 130 toward the support 110. The end of the secondary rod 140 near the seat assembly 200 is pushed away from the main rod 130 by the support assembly 100. The support end 145 of the secondary rod 140 can abut against the secondary seat 220, thereby driving the free end of the secondary seat 220 to gradually move away from the support 110, and thus causing the free end of the main seat 210 to gradually move away from the support 110 until it reaches the extended state.

[0055] refer to Figure 13 and Figure 14 In some embodiments, the cane chair 10 may further include an elastic element 180 disposed within the main rod 130, one end of the elastic element 180 being connected to the sliding element 120, and the other end of the elastic element 180 being connected to the main rod 130. The elastic element 180 is in a retracted state ( Figure 13 The elastic deformation of ) is greater than that in the unfolded state ( Figure 14 The elastic deformation of the slider 120 is used to drive the slider 120 to slide along the main rod 130 in the retracted state, thereby switching to the unfolded state. Figure 14The main rod 130 can have a through groove 130a. The sliding member 120 includes a sleeve 123 and a connecting pin 125 connected to the sleeve 123. The sleeve 123 is slidably fitted onto the main rod 130, and the main seat 210 is 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 with a width greater than the width of the through groove 130a to prevent the connecting pin 125 from coming out of the through groove 130a. One end of the elastic member 180 is connected to the connecting pin 125, and the other end is connected to the main rod 130. During the sliding of the sleeve 123 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 member 180. Of course, it is understood that the elastic member 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.

[0056] 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 the end near the support 110. Simultaneously combined with... Figure 13 and Figure 14 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 locking part 1931 to pass through, thus locking the sliding member 120 to the main rod 130. When the user presses the button 191, the locking part 1931 can be disengaged from the second locking hole 120a, releasing the locking of the sliding member 120. In other words, in the folded state, by using the locking part 1931 passing through the first locking hole 130b and the second locking hole 120a, the sliding member 120 can be locked to the main rod 130, ensuring that the support assembly 100 is stably maintained in the folded state, thus realizing the function of a cane.

[0057] 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.

[0058] When the user needs to use the cane chair 10 as a seat, after unlocking the two secondary seat surfaces 220, pressing button 191 causes the retaining part 1931 to disengage from 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 secondary rods 140 are driven to 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 two secondary seat surfaces 220 are opened relative to the main seat surface 210 until the seat assembly 200 is opened to the open state. Of course, it is understood 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.

[0059] Continue to refer to Figure 14 In some embodiments, the main rod 130 can be fixedly connected to 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 sliding member 120 is smaller than the width of the limiting sleeve 135. During the sliding process of the sliding member 120 sliding down the main rod 130, the sliding member 120 can abut against the limiting sleeve 135, thereby limiting the sliding range of the sliding member 120 on the main rod 130. The handle 150 and the locking structure 190 can limit the sliding range of the sliding member 120 sliding 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.

[0060] 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 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 and the seat component 200 reaches the closed 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. The free end of the main seat 210 gradually moves closer to the main rod 130, and the supporting force of the auxiliary rods 140 on the auxiliary seat 220 gradually decreases. Under the action of gravity, the two auxiliary seat surfaces 220 will rotate relative to the main seat 210 and move closer to the main rod 130. The elastic element 180 inside the main rod 130, which connects the main rod 130 and the slider 120, is stretched and accumulates elastic potential energy, so that the slider 120 and the locking part 1931 can be reliably engaged, so that the support assembly 100 is stably kept in the folded state. The user can also fasten the two auxiliary seat surfaces 220 together, so that the seat assembly 200 is also stably kept in the folded state.

[0061] 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.
