Description

[Technical Field]

[0001] The present invention relates to the technical field of cane chairs, and more particularly to an automatic elastically deployable cane chair. [Background technology]

[0002] A walking stick chair is a combination product of a walking stick and a stool, which is provided for use by people with reduced physical conditions, and can not only assist the user in walking, but also provide a place for the user to sit and rest.

[0003] Prior art also provides walking stick chairs that can be switched between a folded state and an unfolded state to accommodate a walking stick or a walking stick chair. However, this type of disclosed walking stick chair only has the function of switching between a walking stick and a walking stick chair. In actual use, the method of opening the walking stick chair is relatively complicated, and the folding seat must be opened manually. At the same time, the support legs may not be held stably in the designated position on the rod, and the folding seat may bounce back when subjected to external force.

[0004] In order to make it easier for users to use, the prior art has also proposed many solutions to solve the above problems by combining a walking stick and a walking stick chair. However, this type of disclosed prior art solution is relatively cumbersome in the actual manufacturing and use process, and also has a relatively complicated structure, which increases the manufacturing cost and potentially has a relatively high failure rate, which also increases the usage cost to a certain extent and makes it difficult for users to use.

[0005] Generally speaking, although the prior art has proposed many solutions that allow for the conversion of walking sticks and walking stick chairs between a folded state and an unfolded state, users are always hoping for newer walking stick chairs that can reduce the cost of use without affecting ease of use.

[0006] It has the functions of automatic unfolding and easy folding, and the folding seat can be automatically opened by pulling up the switch, and the support legs can be folded and folded to raise the center of gravity of the cane chair. This simplifies the structure of the cane chair, reduces the failure rate, and is advantageous for the assembly and production of cane chairs. There is also a need to propose a completely new cane chair based on the above issues, which requires less processing of the main rod and has little impact on the strength and rigidity of the main rod, further assisting in daily life and improving the user experience.

[0024] As shown in FIG. 1, an automatically elastically deployable walking stick chair includes a hollow main rod 1 extending along an axis, a folding plate mechanism provided on the main rod 1 and capable of deploying and collapsing, and a support leg mechanism that deploys and collapses in conjunction with the folding plate mechanism. A sliding bush 5 is provided on the main rod 1, and is slidable between a first position and a second position along the main rod 1. When the folding plate mechanism converges upward in conjunction with the support leg mechanism, the folding plate mechanism moves the sliding bush 5 to slide from the second position toward the first position; The main rod (1) is provided with a lock hook member (6) and a lift-up switch (7) that slide synchronously along the main rod (1); the bending plate mechanism is provided with an elastic member that deploys the bending plate mechanism relative to the main rod (1) and a hook (43) that engages with the lock hook member (6); the main rod (1) is provided with a return member that drives the hook (43) to maintain the engagement with the lock hook member (6); as shown in FIG. 3 , the hook (43) engages with the lock hook member (6) to restrict the bending plate mechanism from deploying relative to the main rod (1) and to hold the sliding bush (5) in the second position; the lift-up switch (7) is connected to the lock hook member (6); and the lift-up switch (7) slides when subjected to an external force, moving the lock hook member (6) to disengage the hook (43) and release the engagement.

[0025] As shown in FIG. 2, a connecting member 2 is fixed to the middle of the main rod 1, and the sliding bush 5 is disposed above the connecting member 2. The folding plate mechanism includes a support rod 21 pivotally connected to the connecting member 2 and a folding seat plate 4 pivotally connected to the sliding bush 5. The support rod 21 is pivotally connected to the folding seat plate 4, and the hook 43 is disposed at the front end of the bottom of the folding seat plate 4. The elastic member is a torsion spring 9 disposed at the pivotal point between the folding seat plate 4 and the support rod 21. In some embodiments (not shown), the torsion spring 9 may be changed to a tension spring and twisted. The locking hook member 6 and the sliding bush 5 may be directly connected to drive the sliding bush 5 to move toward the locking hook member 6, thereby unfolding the folding seat plate 4. The folding plate mechanism and the support leg mechanism are both connected to the sliding bush 5 to form a linkage, and the support leg mechanism includes a support leg 3 pivotally connected to the connecting member 2 and a retraction rod 24 pivotally connected to the sliding bush 5, and the other end of the retraction rod 24 opposite to the sliding bush 5 is pivotally connected to the middle of the support leg 3.

[0026] As shown in FIG. 5, the folding seat plate 4 includes a main plate 41 and side plates 42 hingedly connected to both sides of the main plate 41. The bottom of the main plate 41 is pivotally connected to a support rod 21. A rotating seat 22 that rotates around the support rod 21 in the axial direction is rotatably connected to the top of the support rod 21. A side plate support rod 23 is rotatably connected to the top of the rotating seat 22. The other end of the side plate support rod 23, opposite to the rotating seat 22, is rotatably connected to the bottom of the side plate 42. When the main plate 41 and the side plate 42 are folded as shown in FIG. When the cane chair converges, they cooperate to form a U-shape, covering the folded support leg 3. Moreover, after the cane chair is folded, the center of gravity of the cane chair is located between the middle and top ends of the main rod 1. When a user uses the folded cane chair to assist walking, the rocking torque is relatively small, and it is relatively easy and effortless to rock it back and forth, thereby reducing the burden on the user. The covering of the support leg 3 also prevents it from directly hitting external objects and causing impacts. The folding seat panel 4 is provided with an anti-slip portion 44 on the outer surface, which may be an anti-slip pattern or an anti-slip bump.

[0027] As shown in FIG. 4, a protrusion 31 is provided on one side of the outer side of the support leg 3, and a magnetic attraction positioning part 45 is provided at the bottom of the side plate 42. When the sliding bush 5 slides to the first position, the magnetic attraction positioning part 45 is magnetically attracted to the protrusion 31, and the magnetic attraction can further help maintain the cane chair in the folded state. A protruding position regulating post 32 is provided on one side of the outer side of the support leg 3. When the sliding bush 5 slides to the first position, the position regulating post 32 abuts against the retraction rod 24 to restrict the sliding bush 5 from sliding upward. When the lift-up switch 7 moves the locking hook member 6 to move upward, the position regulating post 32 restricts the sliding bush 5 from sliding upward. Furthermore, the sliding bush 5 restricts the folding seat plate 4 from moving to convergence, and the hook 43 on the folding seat plate 4 remains stationary, facilitating the separation of the locking hook member 6 and the hook 43. That is, the locking hook member 6 moves upward independently of the hook 43 to complete the disengagement.

[0028] As shown in FIGS. 6 and 7, a first guide groove 11 and a second guide groove 12 are formed on the outer wall of the main rod 1 along the axial direction, and the first guide groove 11 and the second guide groove 12 are respectively connected to the hollow through groove of the main rod 1. The lift-up switch 7 is slidably connected to the main rod 1 by providing a first sliding rod 72 that slides along the first guide groove 11. The sliding bush 5 is provided between the first guide groove 11 and the second guide groove 12, and the sliding bush 5 is located below the second guide groove 12. The lock hook member 6 is slidably connected to the main rod 1 by providing a second sliding rod 62 that slides along the second guide groove 12, and a connecting rod 61 is connected between the first sliding rod 72 and the second sliding rod 62 to form a linkage, and the return member is a return spring 8 that is provided at an upper position of the main rod 1, one end of which is fixed to the inner wall of the hollow through groove and the other end is connected to the connecting rod 61 to drive the lock hook member 6 to slide downward. The connecting rod 61 is rotatably connected to the first sliding rod 72 and the second sliding rod 62, respectively, and forms a structure within the main rod 1 that resembles the movement of a piston. In some embodiments (not shown), the sliding bushing 5 and the locking hook member 6 can be directly attached to the outside of the main rod 1 to achieve a sliding connection, and the sliding bushing 5 and the locking hook member 6 can be provided with a mechanism to prevent circumferential rotation to prevent the locking hook member 6 from coming off the hook laterally, and a return member can be provided on the outer periphery of the main rod to avoid the connecting member and reduce the impact on the tubular structure of the main rod itself.

[0029] As shown in Figure 2, a locking position hole 51 is provided on the sliding bushing 5, and a locking position plunger ball 13 is provided on the outer wall of the main rod 1. When the sliding bushing 5 slides to the second position, the locking position plunger ball 13 fits into the locking position hole 51 to restrict the sliding of the sliding bushing 5, thereby maintaining the cane chair in an unfolded state. In some embodiments (not shown), the locking position plunger ball 13 may be replaced with an elastic pin to achieve position locking with respect to the locking position hole 51. A protruding finger pull position 71 is provided on the lift switch 7, and a protruding auxiliary pull position 52 is provided on the sliding bushing 5, making it easier for users to use.

[0030] The device automatically opens the folding seat 4 by pulling up the switch 7. The bottom of the folding seat 4 is provided with a hook 43 that engages with the locking hook member 6. The hook 43 engages with the locking hook member 6 to prevent the folding seat 4 from unfolding. A return member is provided above the locking hook member 6 to keep the hook 43 engaged with the locking hook member 6, thereby maintaining the folding state of the cane chair. The associated pull-up switch 7 is connected to the top of the locking hook member 6. When the pull-up switch 7 moves upward, the locking hook The locking member 6 is moved to disengage from the hook 43, and the folding seat plate 4 is elastically unfolded under the action of the torsion spring 9, and at the same time the sliding bush 5 is moved and slid, so that the cane chair automatically switches from the folded state to the unfolded state. This simplifies the structure for the automatic elastic unfolding of the cane chair, and can be realized by simply providing the structure for the reciprocating movement of the lifting switch 7 and the locking hook member 6 on the main rod 1, which requires little processing on the main rod 1 and maintains the tubular structure of the main rod 1 itself, resulting in little impact; The lifting switch 7 is located close to the cane part of the walking stick chair, so that the user can pull the lifting switch 7 to open the folding seat 4 without having to bend over. Furthermore, the support legs 3 can be folded upward to a position near the top of the walking stick chair, so that the support points of the support legs 3 against the ground are concentrated and the effect of unevenness of the ground is reduced. When the folding seat 4 is folded, it covers the support legs 3 in a U-shape, raising the center of gravity of the walking stick chair, and the rocking torque is relatively small, so that it is relatively easy and forceless to rock back and forth, reducing the burden on the user.

[0031] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above embodiments, but also include technical solutions consisting of any combination of the above technical features. It should be noted that those skilled in the art may make some improvements and modifications without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the protection scope of the present invention.
