Detailed Implementation
[0030] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.
[0031] The first aspect of this utility model provides a handle 300, as shown in the reference. Figures 1-5 It includes at least a connecting part 320, a grip part 310, and a hook 330. The grip part 310 is used for the user to grip the handle 300 and the cane chair 10. The connecting part 320 is used to connect the grip part 310 to other parts of the cane chair 10 to form a whole cane chair 10. The hook 330 can rotate relative to the connecting part 320, be hidden in the connecting part 320, and extend from the connecting part 320 to be manually hung in the surrounding environment.
[0032] For details, please refer to Figures 2-5 The connecting part 320 is used to connect with the main rod 130 of the cane chair 10. The connecting part 320 is provided with a storage groove 321, and a pivot column 322 is provided in the storage groove 321. The grip part 310 is connected to the connecting part 320 and surrounds the connecting part 320 to form a grip space. There is also a hook 330. One end of the hook 330 is provided with a receiving hole 332 for the pivot column 322 to pass through. The side wall of the receiving hole 332 is provided with an opening 331. The other end of the hook 330 is a free end.
[0033] refer to Figure 2 and Figure 3The hook 330 can rotate around the pivot 322 between a retracted position and an extended position. In the retracted position, the hook 330 is stored in the storage slot 321; in the extended position, the hook 330 and the connecting part 320 form an angle. When the hook 330 is in the extended position, the free end of the hook 330 detaches from the grip part 310 and forms a suspension space with the grip part 310, and the pivot 322 abuts against the opposite end of the receiving hole 332, see reference 2.
[0034] The handle 300 and cane chair 10 provided by this utility model have a storage groove 321 in the connecting part 320 on the handle 300. The hook 330 on the handle 300 is connected to the pivot shaft provided inside the storage groove 321 and can rotate around the pivot shaft, so that the hook 330 can rotate between the closed position and the unfolded position. It can be hidden or unfolded as needed, without making the structure of the handle 300 seem redundant. The hanging rope on the handle 300 can also better adapt to the usage scenario.
[0035] In one embodiment of this utility model, reference is made to Figure 3 and Figure 4 In the folded position, the hook 330 is engaged with the storage slot 321 and the pivot 322 abuts against one end of the receiving hole 332; in the unfolded position, the pivot 322 abuts against the opposite end of the receiving hole 332. The engagement of the receiving hole 332 with the pivot allows the hook 330 to be suspended from the pivot 322 through one end of the hole wall of the receiving hole 332 when in the open position, so that the hook 330 and the grip 310 can reliably suspend the entire cane chair 10 on a wall or other location. During the transition from the unfolded to the retracted position, the user needs to push the free end of the hook 330 into the storage slot 321, while simultaneously moving the end of the hook 330 with the receiving hole 332 away from the support 110. Combined with the engaging mechanism of the free end of the hook 330 and the engagement of the storage slot 321, the hook 330 can be stably secured within the storage slot 321, preventing it from easily detaching. In some more specific viewing configurations, the receiving hole 332 is specifically designed as an oblong hole, facilitating the movement of the hook 330 within it. Once inside the storage slot 321, the pivot pin 322 is located slightly outward from the oblong hole, preventing the hook 330 from detaching.
[0036] Optionally, in conjunction with the foregoing embodiments, in certain specific implementations of one embodiment of this utility model, reference is made to... Figure 4 and Figure 5A first protrusion 333 is provided on the end face of the first end of the hook 330, and a second protrusion 323 is provided on the groove wall of the storage groove 321. During the switching between the closed position and the extended position of the hook 330, the first protrusion 333 passes over the second protrusion 323. The first protrusion 333 and the second protrusion 323 form an elastic blocking structure, which can further ensure that the hook 330 is not easily dislodged when stored in the storage groove 321. During the operation of the hook 330, due to the lever effect, the first protrusion 333 can pass over the second protrusion 323 under the action of external force, thereby preventing it from easily returning, and the hook 330 can remain in the extended position.
[0037] Specifically, in conjunction with the foregoing embodiments, in one implementation method, refer to Figure 4 and Figure 5 The width of the opening 331 is smaller than the width of the pivot post 322. A groove 324 is provided on the wall of the receiving slot 321. In the closed position, the first protrusion 333 is fitted into the groove 324. Regardless of whether the hook 330 is made of metal, wood, or plastic, its design with an opening 331 inherently provides a certain degree of elasticity. Designing the width of the opening 331 to be smaller than the width of the pivot post 322 ensures that the hook 330 will not easily fall off after being installed on the pivot post 322. Further options can be referenced... Figure 4 and Figure 5 The outer width of the opening 331 is smaller than the inner width of the opening 331. On the one hand, this makes it less likely for the hook 330 to fall off on its own after it is installed into the pivot column 322. On the other hand, when it needs to be disassembled, it can be squeezed out from the wider inner opening 331 and removed from the pivot column 322.
[0038] Specifically, in one embodiment, reference is made to Figure 4 A retractable neck 336 is provided at the first end of the hook 330 near the opening of the storage groove 321. When the first protrusion 333 passes over the second protrusion 323, the opening of the storage groove 321 fits into the retractable neck 336. The neck of the retractable neck 336 has a platform that can fit into the surface. The plane containing the edge of the opening of the storage groove 321 fits into the retractable neck 336. The two are in surface contact, which ensures that the hook 330 is relatively stable against the connecting part 320 when it is in the unfolded position.
[0039] In conjunction with the foregoing embodiments, in one specific implementation, refer to Figure 3 and Figure 4The storage groove 321 has a fastening groove 321a on its bottom surface; the hook 330 has a third protrusion 334 on its opposite end. When in the closed position, the third protrusion 334 is engaged in the fastening groove 321a. By providing the matching third protrusion 334 and fastening groove 321a, the hook 330 can be further integrated with the storage groove 321 of the connecting part 320. When the first protrusion 333 returns past the second protrusion 323, the third protrusion 334 can engage with the fastening groove 321a. The fastening groove 321a is a through groove. The bottom end of the fastening groove 321a can lift the hook 330, making it easy to open the hook 330.
[0040] In conjunction with the foregoing embodiments, in one embodiment of this utility model, referring to Figure 5 The pivot column 322 includes a first pivot portion 322b and a second pivot portion 322c. A boss 322a protrudes from the storage groove 321, connecting the first pivot portion 322b and the second pivot portion 322c. The first pivot portion 322b is connected to one side wall of the storage groove 321, and the second pivot portion 322c is connected to the opposite side wall of the storage groove 321. The hook 330 includes a hook arm 335 and a hook arm 335 connected to the hook arm 332b. 35. The first hanging arm 335a and the second hanging arm 335b are on the same end. There is a notch 335c between the first hanging arm 335a and the second hanging arm 335b. The first hanging arm 335a and the second hanging arm 335b respectively form an opening 331 with the hook arm 335. The boss 322a is accommodated in the notch 335c and the first hanging arm 335a is rotatably engaged with the first pivot part 322b. The second hanging arm 335b is rotatably engaged with the second pivot part 322c.
[0041] By designing the pivot column 322 into a segmented structure, namely a first pivot portion 322b and a second pivot portion 322c, and providing a boss 322a between the two pivot portions, a connecting hole can be easily provided on the boss 322a to wed in or drill a screw to connect the grip portion 310 and the connecting portion 320. Corresponding to the structure of the boss 322a, the hook 330 is provided with a segmented structure of a first hanging arm 335a and a second hanging arm 335b to accommodate the boss 322a, allowing for rotational clearance. The boss 322a can be easily accommodated in the formed notch 335c.
[0042] Based on the same technical concept, and referencing Figure 1The second aspect of this utility model also provides a cane chair 10, including a support assembly 100, a seat assembly 200, and a handle 300 as described in any of the first aspects of this utility model; the support assembly 100 includes a slider 120, a main rod 130, a support 110, and two auxiliary rods 140; the main rod 130 and the auxiliary rods 140 are respectively passed through and rotatably connected to the support 110, and the opposite ends of either the main rod 130 or the auxiliary rods 140 extend out of the support 110; the slider 120 is slidably engaged with the main rod 130 and rotatably connected to the seat assembly 200; the slider 120 is used to drive the support assembly 100 to switch between a folded position and an unfolded position, and to drive the seat assembly 200 to fold or unfold, and the auxiliary rods 140 support the seat assembly 200 when unfolded.
[0043] The handle 300 and cane chair 10 provided by this utility model have a storage groove 321 in the connecting part 320 on the handle 300. The hook 330 on the handle 300 is connected to the pivot shaft provided inside the storage groove 321 and can rotate around the pivot shaft, so that the hook 330 can rotate between the closed position and the unfolded position. It can be hidden or unfolded as needed, without making the structure of the handle 300 seem redundant. The hanging rope on the handle 300 can also better adapt to the usage scenario.
[0044] In one embodiment, both auxiliary rods 140 are integral structures and are arranged crosswise at the support 110 in the unfolded state. (See reference) Figure 1 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 main rod 130 and auxiliary rods 140 can be made of aluminum alloy to make the entire cane chair 10 relatively lightweight, making it easy for the elderly to carry, and to give the main rod 130 and auxiliary rods 140 high structural strength to reliably support the weight of the elderly person's body in the unfolded state, ensuring safety during use.
[0045] In one embodiment, in the unfolded state, the two auxiliary rods 140 form an upper included angle space and a lower included angle space, with the main rod 130 passing through one of the upper included angle space and the lower included angle space. Figure 1Taking the example of the main rod passing through the lower included angle space 140b, 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 position and the unfolded position. In the unfolded position, 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 ends of the two auxiliary rods 140 away from the handle 150 can be an isosceles triangle. After 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 140b, 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] 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.
[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
