Description

Technical Field

[0001] This invention belongs to the field of assistive devices for the elderly, specifically relating to a multifunctional integrated cane. Background Technology

[0002] With the development of my country's social economy and the improvement of people's living standards, the demand for elderly care products has increased. Researching and developing products that are suitable for the characteristics of the elderly, have reasonable functions, and are of high quality has become a good opportunity for enterprises to seek development in market competition. As the cultural and educational level of the elderly improves, especially in urban areas where the consumption potential of the elderly market is rising year by year, the elderly's consumption concepts are also changing rapidly. More and more elderly people are now willing to spend more on their health and entertainment. Currently, there are not many manufacturers specializing in multi-purpose walking sticks, and the functions vary greatly. Existing walking sticks on the market have limited functions, only providing basic walking assistance; they are bulky, inconvenient to use, and cannot provide more services for the elderly, making it difficult to play a good role in assisting them in daily life. Summary of the Invention

[0003] The purpose of this invention is to solve the problem of the limited functionality of existing elderly walking sticks, and to provide an elderly walking stick that integrates five functions.

[0004] The present invention provides the following technical solution: a multifunctional integrated cane, including a cane shaft and a handle; the cane shaft is hollow inside and is broken from top to bottom into a first shaft segment, a second shaft segment, ..., an nth shaft segment, each shaft segment having an axially movable linkage rod, the shaft segment having an upper limit position that limits the travel of the linkage rod, and an elastic component connecting the linkage rod and the shaft segment to keep it moving towards the upper limit position;

[0005] The cane segments are connected by hinges to achieve folding, and a locking mechanism restores the cane to a straight state. The locking mechanism includes a fixed hook and a movable locking arm. The fixed hook is installed in the upper segment of the two segments, and the movable locking arm is installed in the lower segment. The upper end of the movable locking arm is a latch that engages with the fixed hook, the lower end is an anti-disengagement hook, and the protrusion in the middle is hinged to the segment. The movable locking arm can swing to both sides. The protrusion on the linkage rod is located in the recess between the back of the latch and the anti-disengagement hook, and the recess smoothly connects to the back of the latch. When the linkage rod is stopped at the upper limit, the latch is held in place by the back of the linkage rod. When the linkage rod moves down, it moves away from the back of the latch, and the protrusion pushes the movable locking arm to disengage the latch from the fixed hook.

[0006] The handle is installed on the first rod section, and the handle's fulcrum is hinged to the pull rod to form a lever. The pull rod and the linkage rod in the first rod section are connected by a pull rod connecting rod. The swing of the pull rod pushes the linkage rod to move. The linkage rod in the cane rod is pushed from top to bottom, and the lower end of the linkage rod is reserved for the movement of the movable locking arm.

[0007] Furthermore, at least three claw supports are hinged to the lower end of the nth segment, which are evenly distributed around the rod body. The lower end of the linkage rod in the nth segment is connected to each claw support by a claw connecting rod. When the linkage rod moves down, it pushes the claw support to open. When the linkage rod moves up, it pulls the claw support to close.

[0008] Furthermore, after a straight section, the back of the hook in the movable locking arm transitions from a slope to a recess, and the linkage rod contacts the straight section. The hook and the fixed locking hook remain engaged, and the claw support gradually opens up.

[0009] Furthermore, the linkage rod within the nth segment includes an upper sleeve, a lower push rod, and a limiting sleeve. The boss is constructed on the upper sleeve, and the limiting sleeve is nested within the nth segment and fixed relative to it. The upper sleeve passes through the limiting sleeve. The lower opening of the upper sleeve has a ring of serrations, and the sleeve wall has a guide slider. The guide slider slides into a guide groove on the inner wall of the limiting sleeve. The lower opening of the limiting sleeve has a ring of teeth, with every two teeth connected to a straight groove extending towards the upper opening of the limiting sleeve. The upper end of the lower push rod is inserted into the upper sleeve, and the lower push rod has a ring of support teeth that mate with the straight grooves one by one. The lower push rod is connected to the elastic component.

[0010] In the first state, the support tooth is located in the straight groove;

[0011] In the second state, the upper sleeve is pushed down by the linkage rod in the (n-1)th rod segment, which pushes the lower push rod to make the support tooth deflect after leaving the straight groove, and slide to the root of the tooth after passing the tip of a tooth. The pull handle is unloaded, and the claw support remains open.

[0012] In the third state, the upper sleeve is pushed down by the linkage rod in the (n-1)th rod segment, which pushes the lower push rod to make the support tooth deflect after disengaging from the current tooth root and enter the next straight groove to return to the first state, while the claw support remains retracted.

[0013] During the deformation process from the first state to the second state, the stroke of the upper sleeve is less than the stroke of the unlocking and locking mechanism;

[0014] In the first, second, and third states, the tip of the support tooth of the lower push rod is always located in the middle position of the sawtooth of the upper sleeve. The upper sleeve is circumferentially fixed, and the sawtooth applies a deflection torque to the support tooth.

[0015] Furthermore, the cane is divided into three sections. The third section is equipped with a flip-up seat plate. When the cane is in a straight position, the seat plate is parallel to the cane. When the cane is folded, the seat plate flips to the top of the third section and is perpendicular to the section.

[0016] Furthermore, the seat plate includes a front panel and a rear panel. The rear panel is connected to the third rod segment. The front panel and the rear panel are connected by hinges on the left and right sides. The bottom edge of the rear panel is connected to a flip-top plate. The front panel has a slot corresponding to the flip-top plate. After the hinges on both sides are unfolded, the flip-top plate supports the slot, and the seat plate deforms into a box. A foldable wheel frame is installed on the back of the rear panel.

[0017] Furthermore, the rear panel is connected to the third segment via an L-shaped rod. The first rod of the L-shaped rod is fixedly connected to the rear panel, and the second rod of the L-shaped rod is hinged to the third segment. The length of the first rod is equal to the distance from the top of the third segment to the hinge axis.

[0018] Furthermore, the segments are connected by a transition piece, which is embedded in the cane shaft. The upper end of the transition piece is hinged to the upper segment, and the lower end is hinged to the lower segment.

[0019] Furthermore, the elastic component is a compression spring, which is sleeved on the linkage rod, with its upper end supporting the linkage rod and its lower end supporting the support point on the rod segment.

[0020] Furthermore, the locking mechanism and hinge are located on opposite sides of the lever segment.

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] This invention provides a multifunctional integrated cane that can transform into five forms. The first form is a standard point-support cane with the claw support fully retracted, characterized by its flexibility but less stable support. The second form is a multi-point-support cane with the claw support remaining open, characterized by good stability but less cumbersome. The advantages and disadvantages of the first and second forms complement each other, achieving multiple benefits with a single cane. In the third form, the cane shaft folds, the claw support remains open, and the seat plate flips to the top of the third shaft, transforming the cane into a stool. In the fourth form, the cane shaft is straight, the seat plate unfolds and transforms into a frame, the wheel frame extends, and the cane transforms into a pullable cart. In the fifth form, the cane shaft folds, the claw support retracts, and the seat plate fits against the third shaft, resulting in the smallest cane size for easy storage. These five forms cover various usage scenarios, providing convenience and saving users the cost of purchasing specialized tools. Attached Figure Description

Detailed Implementation

[0035] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0036] like Figures 1-5As shown: A multifunctional integrated cane includes a cane shaft and a handle; the cane shaft is hollow inside and is broken from top to bottom into a first shaft segment, a second shaft segment, ..., an nth shaft segment, each shaft segment having an axially movable linkage rod 4 passing through it, the linkage rods 4 abutting each other between the shaft segments, the shaft segment having an upper limit position that restricts the travel of the linkage rod 4, and the linkage rod 4 being connected to the shaft segment by an elastic component that keeps it tending to move towards the upper limit position.

[0037] Specifically, the elastic component is a compression spring 20, which is sleeved on the linkage rod 4. The upper end of the compression spring 20 supports the linkage rod 4, and the lower end supports the support point on the rod segment. Two shear pins 21 are drilled into the rod segment, and the lower end of the compression spring 20 rests on the shear pins 21. The linkage rod 4 has a guide plug 22 integrally fixed to it. The outer circumference of the guide plug 22 slides in contact with the inner wall of the rod segment, and the upper end of the compression spring 20 rests on the guide plug 22.

[0038] like Figure 3 The diagram shows the connection between the second segment 2 and the third segment 3; the connection structures between the remaining segments are the same. The segments are connected by hinges to achieve folding, and a locking mechanism 5 restores the cane to a straight state. The locking mechanism 5 and the hinges are located on opposite sides of the segments. A transition piece 19 connects the segments, embedding itself within the cane. The upper end of the transition piece 19 is hinged to the upper segment, and the lower end is hinged to the lower segment. The inner side of the transition piece 19 is in contact with the linkage rod 4. Therefore, when the locking mechanism 5 is not disengaged, the upper and lower segments cannot move relative to each other, and the cane cannot be folded back. The transition piece 19 allows the cane to be folded so that the two segments can be completely aligned.

[0039] The locking mechanism 5 includes a fixed locking hook 5.1 and a movable locking arm 5.2. The fixed locking hook 5.1 has a downward-facing hook body and is installed in the upper rod section between the two rod sections. The movable locking arm 5.2 is installed in the lower rod section between the two rod sections. The upper end of the movable locking arm 5.2 has a catch hook 5.2.1 that engages with the fixed locking hook 5.1, the lower end has an anti-disengagement hook 5.2.2, and the protrusion 5.2.3 in the middle is hinged to the rod section. The movable locking arm 5.2 can swing on both sides, that is, the catch hook 5.2.1 can swing back and forth between the inner wall of the rod section and the linkage rod 4, which can unlock the catch hook 5.2.1. The anti-disengagement hook 5.2.2 can also swing back and forth between the inner wall of the rod section and the linkage rod 4. The protrusion 4.1 on the linkage rod 4 is located in the recess between the back of the hook and the anti-disengagement hook 5.2.2, and the recess smoothly connects to the back of the hook. The linkage rod 4 is locked at the upper limit position, and the hook 5.2.1 is held against the linkage rod 4 to maintain engagement with the fixed locking hook 5.1. When the linkage rod 4 moves down, it moves away from the back of the hook, and the protrusion 4.1 pushes the movable locking arm 5.2 to disengage the hook 5.2.1 from the fixed locking hook 5.1. After the hook 5.2.1 disengages from the fixed locking hook 5.1, the locking mechanism 5 is unlocked, and the cane can be folded freely.

[0040] like Figure 2 As shown: the handle 6 is installed on the first rod segment 1 and is located at the top of the first rod segment 1. The fulcrum of the handle 6 is hinged to the pull handle 7 to form a lever. One end of the pull handle 7 passes through the notch on the first rod segment 1. The pull handle 7 and the linkage rod 4 in the first rod segment 1 are connected by the pull handle connecting rod 8. The pull handle connecting rod 8 converts the rotational motion of the pull handle 7 into linear motion. The swing of the pull handle 7 pushes the linkage rod 4 to move. The linkage rod 4 in the cane stick pushes from top to bottom, and unlocks the locking mechanism 5 between each rod segment simultaneously. The lower end of the linkage rod 4 is reserved with a movable locking arm 5.2 for movement.

[0041] The cane has a gripping mechanism at the bottom, which can be used to catch dropped objects. This gripping mechanism is operated via handle 7. Figure 4 As shown: At least three claw supports 9, evenly distributed around the rod body, are hinged to the lower end of the nth rod segment. In this embodiment, n is 3. The lower end of the linkage rod 4 in the nth rod segment is connected to each claw support 9 by a claw connecting rod 10. The linkage rod 4 moves downward to push the claw support 9 open, and moves upward to pull the claw support 9 close. A multi-finned adapter 11 is installed at the bottom of the linkage rod 4. Pins are inserted between the fins to connect the claw connecting rod 10. The claw support 9 is hinged to the support pad 12 outside the third rod segment 3. The hinge axis of the claw connecting rod 10 and the hinge axis of the support pad 12 are at two positions on the claw support 9, so that the claw connecting rod 10 can push the claw support 9 to rotate. Within a certain range of motion of the pull handle 7, the downward movement of the linkage rod 4 is insufficient to trigger the locking mechanism 5, but the movement of the linkage rod 4 will inevitably cause the claw support 9 to move.

[0042] like Figure 3 As shown: The linkage rod 4 moves downward within a certain range without triggering the locking mechanism 5, which is achieved in the following way: After a straight section, the back of the hook in the movable locking arm 5.2 transitions to a recess by a slope. The linkage rod 4 contacts the straight section, and the hook 5.2.1 and the fixed hook 5.1 remain engaged, while the claw support 9 gradually opens. When the linkage rod 4 moves downward, its top end must slide past the straight section of the hook's back before the movable locking arm 5.2 can swing towards the linkage rod 4. When the top end of the linkage rod 4 has not left the straight section of the hook's back, the boss 4.1 of the linkage rod 4 remains in the recess of the movable locking arm 5.2 and does not reach the anti-disengagement hook 5.2.2, and the boss 4.1 will not push the movable locking arm 5.2.

[0043] After the pull handle 7 releases force, the claw support 9 can still remain open. For example... Figure 5 , Figure 6 , Figure 7As shown: The linkage 4 within the third segment 3 includes an upper sleeve 13, a lower push rod 14, and a limiting sleeve 15. The limiting sleeve 15 is nested within the nth segment and fixed relative to the nth segment. The upper sleeve 13 passes through the limiting sleeve 15. The lower opening of the upper sleeve 13 has a ring of serrations, and the sleeve wall has a guide slider 13.1. The guide slider 13.1 slides into the guide groove 15.1 on the inner wall of the limiting sleeve 15. The lower opening of the limiting sleeve 15 has a ring of teeth, with every two teeth connected to a straight groove 15.2 extending towards the upper opening of the limiting sleeve 15. The upper end of the lower push rod 14 is inserted into the upper sleeve 13. The lower push rod 14 has a ring of support teeth 14.1 that engage with the straight groove 15.2 one by one. The lower push rod 14.1 is connected to the elastic component.

[0044] In the first state, the support tooth 14.1 is located in the straight groove 15.2. At this time, the claw support 9 is retracted and the handle 7 is not subjected to external force.

[0045] In the second state, the pull handle 7 is pulled, and the upper sleeve 13 is pushed down by the linkage rod 4 in the second rod section 2. This pushes the lower push rod 14, causing the support tooth 14.1 to disengage from the straight groove 15.2 and deflect, passing the tip of one tooth and sliding to the root of the tooth. The pull handle 7 is relieved of force, and the claw support 9 remains open. During the deformation process from the first state to the second state, the stroke of the upper sleeve 13 is less than the stroke of the unlocking and locking mechanism 5. That is, in the second state, the claw support 9 is open but does not reach the maximum opening angle. Its function is to form multi-point support after the claw support 9 is opened, but the claw support 9 will not obstruct the upper sleeve 13 when it continues to move down to unlock the locking mechanism 5.

[0046] In the third state, the upper sleeve 13 is pushed down by the linkage rod 4 in the second rod segment 2, which pushes the lower push rod 14 to disengage the support tooth 14.1 from the current tooth root and deflect it, entering the next straight groove 15.2 to return to the first state, while the claw support 9 remains retracted.

[0047] In the first, second, and third states, the tip of the support tooth 14.1 of the lower push rod 14 is always located in the middle position of the saw teeth of the upper sleeve 13. The upper sleeve 13 is circumferentially fixed, and the saw teeth apply a deflection torque to the support tooth 14.1.

[0048] The first state of the cane is a regular point-supported cane, characterized by its flexibility but with poor stability. The second state of the cane is a multi-point-supported cane, characterized by its good stability but with its clumsiness. The advantages and disadvantages of the first and second states of the cane complement each other, achieving multiple advantages with one type of cane.

[0049] When transforming from the first state to the second state, pushing the linkage rod 4 all the way to unlock the locking mechanism 5 will cause the cane stick to fold and the claw support 9 to be in the open state. When transforming from the second state to the third state, pushing the linkage rod 4 all the way to unlock the locking mechanism 5 will cause the cane stick to fold and the claw support 9 to be in the closed state.

[0050] like Figure 9 As shown: The cane is divided into three sections. The second section 2 and the third section 3 are of equal length, while the first section 1 is slightly shorter. A flip-up seat 16 is installed on the third section 3. When the cane is in a straight position, the seat 16 is parallel to the cane. When the cane is folded, the seat 16 flips to the top of the third section 3 and is perpendicular to the section. At this time, the cane transforms into a stool, with the three sections serving as the legs of the seat 16. The first section 1 has the handle 6 facing upwards. The shorter height of the first section 1 compared to the second and third sections 3 accommodates the handle 6, and the claw support 9 is also in an open position at this time.

[0051] like Figure 8 , Figure 10 As shown: The seat plate 16 includes a front panel 16.1 and a rear panel 16.2. The rear panel 16.2 is connected to the third rod segment 3. The front panel 16.1 and the rear panel 16.2 are connected by hinges 16.3 on the left and right sides. The bottom edge of the rear panel 16.2 is connected to a flip-up base plate 16.4. The front panel 16.1 has a corresponding slot for the flip-up base plate 16.4. After the hinges 16.3 on both sides are unfolded, the flip-up base plate 16.4 supports the slot, and the seat plate 16 transforms into a box. A foldable wheel frame 17 is installed on the back of the rear panel 16.2. When the seat plate 16 is transformed into a box and the wheel frame 17 is unfolded, the cane is in a straight rod state, and the cane becomes a pullable trolley. When the seat plate 16 is folded into a plate-like structure, it fits tightly against the cane and does not affect the original function of the cane.

[0052] The rear panel 16.2 is connected to the third segment 3 via an L-shaped rod 18. The first rod of the L-shaped rod 18 is fixedly connected to the rear panel 16.2, and the second rod of the L-shaped rod 18 is hinged to the third segment 3. The length of the first rod is equal to the distance from the top of the third segment 3 to the hinge axis.

[0053] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
