Description

Technical Field

[0001] This application relates to the field of cane technology, specifically to a multifunctional cane. Background Technology

[0002] In daily life, canes serve as an aid to walking and are of great significance to the elderly, disabled, and other people with mobility impairments. The main function of canes is to provide support for the user, help them maintain balance, reduce the burden on the lower limbs, and thus enable them to walk more stably and safely.

[0003] However, as people's demands for quality of life gradually increase, the single function of a walking stick is no longer sufficient to meet the actual needs of users in various scenarios. For example, when users feel tired during long walks, they often need to find resting facilities such as seats to rest temporarily. However, in many places, such as outdoor park paths, mountain trails, and areas around shopping malls where there is a large flow of people or inadequate public facilities, the number of seats is limited and their distribution is uneven, making it difficult for users to find a suitable resting mat in a timely manner. In this situation, users can only stand up to rest, which not only fails to effectively relieve fatigue but may also aggravate physical discomfort due to prolonged standing. Utility Model Content

[0004] One objective of this application is to provide a multifunctional cane to solve the problem that existing canes cannot provide a resting function.

[0005] To achieve the above objectives, the technical solution adopted in this application is: a multifunctional cane, comprising:

[0006] A retractable unit, comprising a retractable base and a retractable main rod, wherein the retractable main rod is vertically slidably mounted on the retractable base and is slidable relative to the retractable base between a first position and a second position;

[0007] The rod unit includes a gripping main rod and two supporting legs. The gripping main rod and the two supporting legs are pivotally mounted on the retractable base. The gripping main rod and the two supporting legs are linked with the retractable main rod. The retractable main rod is adapted to slide between a first position and a second position to drive the gripping main rod and the two supporting legs to pivotally retract or pivotally unfold relative to each other.

[0008] The cane includes a seat unit comprising a main seat portion and two side seat portions. The two side seat portions are rotatably disposed on opposite sides of the main seat portion. The side seat portions can be folded or unfolded relative to the main seat portion. A first hinge rod connects the main seat portion and the folding base, and a second hinge rod connects the main seat portion and the gripping main rod. When the multi-functional cane is folded, the gripping main rod and the two support legs pivot relative to each other and retract. The main seat portion retracts to fit against the gripping main rod, and the two side seat portions fold to cover the gripping main rod and the two support legs. When the multi-functional cane is unfolded, the gripping main rod and the two support legs pivot relative to each other and unfold. The main seat portion unfolds away from the gripping main rod, and the two side seat portions unfold. The two support legs respectively abut against and support the two side seat portions.

[0009] As a preferred embodiment, the side chair portion includes a covering portion located on the side of it away from the main chair portion. When the main chair portion is fitted against the main grip bar and the side chair portion is folded, the side chair portion covers the main grip bar and the support legs. The covering portion abuts against the main grip bar and the support legs. The covering portion is adapted to restrict the main chair portion from rotating and unfolding relative to the main grip bar and to restrict the main grip bar and the two support legs from pivoting and unfolding relative to each other.

[0010] As another preferred embodiment, a locking lever and a locking element are slidably provided on the main chair part. The locking lever is linked with the locking element. The locking lever is adapted to drive the locking element to a third position to lock the side chair part in a folded state or to a fourth position to unlock the side chair part in a folded state. A first torsion spring is provided between the main chair part and the side chair part. The first torsion spring is adapted to push the side chair part to rotate and unfold when the side chair part is unlocked.

[0011] In a further preferred embodiment, a first elastic member is provided between the locking wrench and the main chair part. One end of the first elastic member abuts against the locking wrench, and the other end of the first elastic member abuts against the main chair part. Thus, the first elastic member is adapted to push the locking wrench so that the locking wrench and the locking member are held in the third position.

[0012] Furthermore, the locking element includes a locking seat and two locking hooks. The locking hooks are movably disposed on the locking seat and can slide relative to the locking seat between a locked position and an unlocked position. A second elastic element is disposed between the locking hooks and the locking seat. The second elastic element is adapted to push the locking hooks so that the locking hooks are held in the locked position. A locking buckle is disposed on the side seat. When the locking seat is in the third position and the locking hooks are in the locked position, the locking buckle and the locking hooks lock together to lock the side seat.

[0013] Furthermore, the main chair is provided with a first sliding groove and a second sliding groove. One end of the first hinge rod is hinged to the folding base, and the other end of the first hinge rod is slidably hinged to the first sliding groove. One end of the second hinge rod is hinged to the gripping main rod, and the other end of the second hinge rod is slidably hinged to the second sliding groove. Thus, when the main chair rotates and unfolds, the end of the first hinge rod can slide in the first sliding groove, and the end of the second hinge rod can slide in the second sliding groove.

[0014] Furthermore, a second torsion spring is provided between the first hinge rod and the folding base. The two torsion arms of the second torsion spring respectively abut against the folding base and the first hinge rod. The second torsion spring is adapted to apply a force to the first hinge rod so that the first hinge rod can push the main chair part to rotate and unfold.

[0015] Furthermore, a third elastic member is provided between the second hinge rod and the main chair part. One end of the third elastic member abuts against the end of the second hinge rod that is hinged to the second slide groove, and the other end of the third elastic member abuts against the main chair part. The third elastic member is adapted to push the end of the second hinge rod to slide in the second slide groove so that the main chair part can rotate and unfold.

[0016] Furthermore, the retractable base is provided with a sliding groove and three pivoting grooves. The three pivoting grooves are arranged around the periphery of the sliding groove. The retractable main rod can be vertically slidably arranged in the sliding groove. The gripping main rod and the two supporting legs are respectively pivotally arranged in the three pivoting grooves. The retractable main rod is provided with three guide rail grooves. The gripping main rod and the two supporting legs are each provided with a guide boss. The guide bosses cooperate with the guide rail grooves. Thus, when the retractable main rod moves between the first position and the second position, it can drive the gripping main rod and the two supporting legs to pivotally retract or pivotally unfold relative to each other.

[0017] Furthermore, a fourth elastic element is provided between the retractable main rod and the retractable base. One end of the fourth elastic element abuts against the retractable main rod, and the other end of the fourth elastic element abuts against the retractable base. The fourth elastic element is adapted to push the retractable main rod so that the retractable main rod moves to the second position.

[0018] Compared with the prior art, the beneficial effects of this application are as follows:

[0019] When the multi-functional cane is folded, the main grip and two support legs pivot relative to each other and retract, the main chair rotates and retracts to fit against the main grip, and the side chairs fold relative to the main chair to cover the main grip and support legs. The multi-functional cane can then be used as a regular cane to assist the user in walking. When the multi-functional cane is unfolded, the main grip and two support legs pivot relative to each other and unfold, the main chair rotates and unfolds away from the main grip, the side chairs unfold relative to the main chair, and the two support legs abut against the two sides of the chair. The multi-functional cane can then be used as a resting seat to help the user relieve fatigue. In addition, the multi-functional cane is structurally stable in both the folded and unfolded states, and the folding and unfolding operations are simple, effortless, and provide a good user experience.

Detailed Implementation

[0032] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0033] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0034] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0035] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0036] like Figure 1-11As shown, this application provides a multi-functional cane, which has two forms: a folded state and an unfolded state. When the multi-functional cane is in the folded state, it can be used as a regular cane for the user to use to assist walking. When the multi-functional cane is in the unfolded state, it can be used as a resting seat for the user to use to sit down and rest.

[0037] Furthermore, the multi-functional cane includes a folding unit 100, a bar unit 200, and a seat unit 300.

[0038] like Figure 1-7 As shown, the retracting unit 100 includes a retracting main rod 110 and a retracting base 120. A sliding groove 121 is provided on the retracting base 120. The retracting main rod 110 can be vertically slidably disposed in the sliding groove 121, and thus the retracting main rod 110 can slide up and down relative to the retracting base 120 between a first position and a second position.

[0039] The pole unit 200 includes a gripping main pole 210 and two support legs 220. The top of the gripping main pole 210 has a handle for the user to grip, and the bottom of the gripping main pole 210 has a foot pad that contacts the ground. The retractable base 120 has three pivoting slots 122, which surround the sliding slot 121. The gripping main pole 210 and the two support legs 220 are pivotally mounted within the pivoting slots 122, and are linked to the retractable main pole 110. The retractable main pole 110 has... Three guide rail grooves 111, a guide boss 230 is provided on the main gripping rod 210 and the two support legs 220. The guide boss 230 cooperates with the guide rail grooves 111 and can slide within the guide rail grooves 111. When the retracting main rod 110 slides relative to the retracting base 120 to the first position, the retracting main rod 110 drives the main gripping rod 210 and the two support legs 220 to pivot and retract relative to each other. When the retracting main rod 110 slides relative to the retracting base 120 to the second position, the retracting main rod 110 drives the main gripping rod 210 and the two support legs 220 to pivot and unfold relative to each other.

[0040] The seat unit 300 includes a main seat portion 310 and two side seat portions 320. The side seat portions 320 are rotatably disposed on both sides of the main seat portion 310. The side seat portions 320 can be rotated and folded or rotated and unfolded relative to the main seat portion 310. When the side seat portions 320 are folded, the two side seat portions 320 are respectively arranged perpendicular to the main seat portion 310, and the seat unit 300 has an overall U-shaped structure. When the side seat portions 320 are unfolded, the two side seat portions 320 are respectively laid flat with the main seat portion 310, and the seat unit 300 has an overall I-shaped structure. A first hinge rod 410 is connected between the main seat portion 310 and the folding base 120, and a second hinge rod 420 is connected between the main seat portion 310 and the holding main rod 210, so that the main seat portion 310 can be rotated and folded or rotated and unfolded relative to the holding main rod 210.

[0041] Specifically, when the multi-functional cane is folded, the folded main bar 110 is in the first position, the gripping main bar 210 and the two support legs 220 pivot relative to each other and retract, the main chair part 310 rotates and retracts to fit against the gripping main bar 210, and the two side chair parts 320 fold to cover the gripping main bar 210 and the two support legs 220. The two side chair parts 320 are suitable for locking the multi-functional cane in the folded state. When the multi-functional cane is unfolded, the folded main bar 110 is in the second position, the gripping main bar 210 and the two support legs 220 pivot relative to each other and unfold, the main chair part 310 rotates and unfolds away from the gripping main bar 210, the two side chair parts 320 unfold, and the tops of the two support legs 220 respectively abut against and support the two side chair parts 320. The main chair part 310 and the two side chair parts 320 form a sitting surface for the user to rest.

[0042] like Figure 7-11As shown, a locking lever 510 and a locking element are slidably disposed on the main chair portion 310. The locking element includes a locking seat 520 and two locking hooks 530. The locking lever 510 and the locking seat 520 are slidably disposed on the main chair portion 310, and a linkage rod 540 connects the locking lever 510 and the locking seat 520 to realize the linkage between the locking lever 510 and the locking seat 520. Thus, the locking lever 510 is adapted to be actuated to drive the locking seat 520 to slide between a third position and a fourth position along a first direction (the first direction is the length direction of the main chair portion 310). The two locking hooks 530 are disposed on the locking seat 520. The locking hook 530 and the locking seat 520 define a locking space. The side seat 320 is provided with a locking buckle 321 that is adapted to the locking hook 530. When the locking lever 510 and the locking seat 520 slide to the third position, the locking buckle 321 is inserted into the locking space. The locking hook 530 and the locking buckle 321 abut against each other to lock the side seat 320. When the locking lever 510 and the locking seat 520 slide to the fourth position, the locking buckle 321 is disengaged from the locking space. The locking buckle 321 and the locking seat 520 are misaligned to unlock the side seat 320. The user can lock and unlock the side seat 320 by moving the locking lever 510. Preferably, a first torsion spring 610 is provided between the main chair part 310 and the side chair part 320. The two torsion arms of the first torsion spring 610 abut against the main chair part 310 and the side chair part 320 respectively. The first torsion spring 610 is adapted to push the side chair part 320 to rotate and unfold relative to the main chair part 310. That is, after the side chair part 320 is unlocked, it can automatically rotate and unfold under the action of the first torsion spring 610.

[0043] It is worth mentioning that a first elastic element 620 is provided between the locking lever 510 and the main chair part 310. The first elastic element 620 can preferably be implemented as a compression spring. The first elastic element 620 is sleeved on the linkage rod 540. One end of the first elastic element 620 abuts against the locking lever 510, and the other end abuts against the main chair part 310. The first elastic element 620 is adapted to apply force to the locking lever 510 to drive the locking lever 510 to move the locking seat 520 to... In the third position, when an external force is applied to the locking lever 510, the external force moves the locking lever 510, causing the locking seat 520 to move to the fourth position to unlock the side chair 320. When no external force is applied to the locking lever 510, the first elastic member 620 pushes the locking lever 510, causing the locking seat 520 to move to the third position to lock the side chair 320. In short, the user only needs to move the locking lever 510 when unlocking the side chair 320 and release the locking lever 510 when locking the side chair 320.

[0044] Furthermore, the locking seat 520 has two symmetrically arranged receiving grooves, both of which extend along a second direction (the second direction is the width direction of the main chair part 310). Two locking hooks 530 are slidably disposed in the two receiving grooves respectively. The locking hooks 530 can slide between a locked position and an unlocked position along the second direction. When the locking hooks 530 are in the locked position, the locking buckles 321 cannot enter or exit the locking space. When the locking hooks 530 are in the unlocked position, the locking buckles 321 can enter or exit the locking space. A second elastic member 630 is also provided in the receiving groove. The second elastic member 630 can preferably be implemented as a compression spring. One end of the second elastic member 630 abuts against the groove wall of the receiving groove, and the other end of the second elastic member 630 abuts against the locking hooks 530. The second elastic member 630 is adapted to apply force to the locking hooks 530 to drive the locking hooks 530 to move to the locked position. Both the locking buckles 321 and the locking hooks 530 have a guide slope and a locking plane. The above structure simplifies the operation of locking the side seat 320. The user only needs to rotate the side seat 320 to the folding position to lock the side seat 320.

[0045] Specifically, the process of locking the side seat 320 can be divided into two stages. The first stage is the rotation of the side seat 320 from the unfolded position to the folded position, and the second stage is the rotation of the side seat 320 to the folded position. In the first stage, the guide slope of the locking buckle 321 abuts against the guide slope of the locking hook 530. As the side seat 320 rotates, the locking buckle 321 pushes the locking hook 530 from the locked position to the unlocked position and embeds it into the locking space. In the second stage, the locking buckle 321 is embedded in the locking space, and the locking hook 530 moves to the locked position under the action of the second elastic member 630. The locking plane of the locking buckle 321 abuts against the locking plane of the locking hook 530, and the locking buckle 321 cannot disengage from the locking space. The side seat 320 is locked in the folded position. In other words, the user only needs to rotate the side seat 320 to the folded position to lock the side seat 320.

[0046] Furthermore, the main chair portion 310 is provided with a first sliding groove 311 and a second sliding groove 312. One end of the first hinge rod 410 is hinged to the folding base 120, and the other end of the first hinge rod 410 is slidably hinged to the first sliding groove 311. One end of the second hinge rod 420 is hinged to the gripping main rod 210, and the other end of the second hinge rod 420 is slidably hinged to the second sliding groove 312. During the process of the main chair portion 310 rotating and unfolding relative to the gripping main rod 210, the end of the first hinge rod 410 can slide from one end of the first sliding groove 311 to the other end, and the end of the second hinge rod 420 can slide from one end of the second sliding groove 312 to the other end.

[0047] A second torsion spring 640 is provided between the first hinge rod 410 and the folding base 120. The two torsion arms of the second torsion spring 640 respectively abut against the folding base 120 and the first hinge rod 410. The second torsion spring 640 is adapted to apply force to the first hinge rod 410 so that the first hinge rod 410 can push the main chair part 310 to rotate and unfold relative to the gripping main rod 210.

[0048] A third elastic element 650 is provided between the second hinge rod 420 and the main chair part 310. The third elastic element 650 can preferably be implemented as a compression spring. One end of the third elastic element 650 abuts against the end of the second hinge rod 420 that is hinged to the second slide groove 312, and the other end of the third elastic element 650 abuts against the main chair part 310. The third elastic element 650 is adapted to apply a force to the end of the second hinge rod 420 so that the end of the second hinge rod 420 slides from one end of the second slide groove 312 to the other end, assisting the main chair part 310 in rotating and unfolding relative to the main support rod 210.

[0049] Furthermore, a fourth elastic element 660 is provided between the retractable main rod 110 and the retractable base 120. The fourth elastic element 660 can preferably be implemented as a compression spring. One end of the fourth elastic element 660 abuts against the retractable main rod 110, and the other end of the first elastic element 620 abuts against the retractable base 120. The fourth elastic element 660 is adapted to apply force to the retractable main rod 110 so that the retractable main rod 110 can be moved to the second position, causing the holding main rod 210 and the two support legs 220 to pivot relative to each other to unfold or retract.

[0050] Furthermore, the side chair portion 320 includes a covering portion 322 located on the side away from the main chair portion 310. When the main chair portion 310 is folded and fitted against the main grip bar 210 and the side chair portion 320 is in the folded position, the side chair portion 320 is adapted to cover the main grip bar 210 and the two support legs 220, such that the covering portion 322 abuts against the main grip bar 210 and the support legs 220 to generate a force. This force is adapted to resist the second torsion spring 640, the third elastic member 650 and the fourth elastic member 660 to limit the rotation and unfolding of the main chair portion 310 relative to the main grip bar 210 and to limit the pivoting and unfolding of the main grip bar 210 and the two support legs 220 relative to each other.

[0051] In summary, when unfolding the multi-functional cane, the user moves the locking lever 510 to unlock the two side chair sections 320. After the side chair sections 320 are unlocked, they rotate and unfold under the action of the first torsion spring 610, causing the covering part 322 to separate from the gripping main rod 210 and the support leg rod 220, thus releasing the lock on the gripping main rod 210, the support leg rod 220, and the main chair section 310. Under the action of the second torsion spring 640 and the third elastic element 650, the main chair section 310 rotates and unfolds relative to the gripping main rod 210. The retractable main rod 110 moves to the second position under the action of the fourth elastic element 660, causing the gripping main rod 210 and the two support leg rods 220 to pivot and unfold relative to each other. The top of the support leg 220 abuts against the two side chair parts 320, and the support leg 220 provides support for the two side chair parts 320. When folding the multi-functional cane, the user rotates and folds the main grip 210 and the two support legs 220, as well as the main chair part 310 and the two side chair parts 320. The main grip 210 and the two support legs 220 are pivoted relative to each other and folded together. The main chair part 310 is pressed against the main grip 210. The two side chair parts 320 are rotated to the folded position. The side chair parts 320 are locked in the folded position and cover the main grip 210 and the two support legs 220. The side chair parts 320 lock the main grip 210, the support legs 220 and the main chair part 310.
