Description

Technical Field

[0001] This utility model relates to an assistive device, and more particularly to a walking stick. Background Technology

[0002] Assistive devices for walking, as the name suggests, are tools used to assist users in walking. They are designed to help users with limited mobility due to muscle weakness, lower limb injuries, or other reasons, providing support to facilitate walking. Assistive devices for walking come in many forms, such as canes or walking aids. Generally, a traditional cane consists of a handle, a shaft, and a base, with the base often having multiple legs to provide multiple points of contact with the ground for support. When using a cane for walking, users gain more support, distribute the burden on their feet, and prevent falls. Therefore, in addition to people with mobility impairments, the use of canes for walking assistance is becoming increasingly popular among the general public, and they can also be used in activities such as mountain climbing or hiking.

[0003] The act of using a walking stick can be roughly broken down as follows: The user first holds the stick and extends it in the direction of travel, placing the base on the ground along the path to form a fulcrum, and then takes a step. During the step, the stick will rotate relative to the base, and part of the user's body weight will be applied to the stick. Therefore, the base of the stick must remain firmly in contact with the ground during the step and cannot move; otherwise, the supporting force may be dispersed or slip. If the user's force is dispersed, resulting in insufficient downward pressure, and is accompanied by lateral force, the base may slip, causing the user to fall and resulting in danger.

[0004] However, traditional walking sticks, due to their base design, are only suitable for use on flat surfaces and cannot adapt to uneven or rugged terrain. On such uneven surfaces, the base's legs may partially dangle, resulting in insufficient contact points and ineffective grip and support for the user. Furthermore, there are walking sticks with plastic bases, which are made by ultrasonically fusing and joining multiple plastic units. This manufacturing process is quite difficult and costly. In addition, the base produced in this way, due to the tight bonding caused by ultrasonic fusion, has poor elasticity and lacks spatial margin, resulting in a poor user experience and limited anti-slip properties.

[0005] Therefore, it is necessary to improve the walking stick to enhance the user's safety. Utility Model Content

[0006] The main objective of this invention is to provide a walking stick whose base assembly can obtain sufficient grip when in contact with different types of ground.

[0007] To achieve the aforementioned objectives, the walking stick proposed in this utility model comprises:

[0008] A cane assembly having a top end and a bottom end;

[0009] A handle, which is located at the top of the cane assembly; and

[0010] A base assembly is disposed at the bottom end of the cane assembly, the base assembly having:

[0011] A lower plate has a top surface and a bottom surface with multiple connecting holes extending through it, and the lower plate is elastic; and

[0012] An upper plate is disposed on the top surface of the lower plate. The upper plate has a top surface, a bottom surface, and a plurality of connecting members. The plurality of connecting members are connected to the bottom surface and respectively pass through the plurality of connecting holes, thereby allowing the upper plate and the lower plate to engage with each other. Each connecting member has:

[0013] A connecting rod, one end of which is connected to the lower part of the upper plate and passes through one of the connecting holes; and

[0014] A coupling head is connected to the other end of the coupling rod and protrudes from the bottom surface of the lower plate. The coupling head is elastic and forms multiple lobes that are spaced apart from each other and extend downward.

[0015] Therefore, the advantage of this utility model lies in the fact that its upper and lower plates are connected to each other through a connecting member and a connecting hole. The connecting rod of the connecting member passes through the connecting hole, allowing the lower plate to move slightly relative to the upper plate, providing a certain degree of deformation margin. The lower plate itself is also elastic, better adapting to terrain changes and thus increasing the contact area with the ground. It is worth further noting that the connection method between the upper and lower plates is not a fixed lock, but rather allows for a certain degree of movement and flexibility. This "free-fitting" design not only adapts to changes in different terrains but also automatically adjusts the posture of the lower plate when the direction and angle of force are inconsistent, keeping the overall base assembly stable and in contact with the ground. This structural design allows the upper and lower plates to achieve better self-adjustment and load distribution in different application environments, contributing to improved overall stability and durability. Furthermore, when the lower plate deforms due to external forces, the connecting head of the connecting member can also touch the ground. Because the connecting head has multiple petals with spacing between them, and the connecting head itself is elastic, it can generate additional ground contact area in a deformed state, further enhancing grip and anti-slip performance. In other words, the base assembly of this invention forms a flexible and freely matching connection between the upper and lower plates through a connecting component, giving the overall structure higher deformation adaptability and stability. When the user applies force to bring the base assembly into contact with the ground, the multi-petal design of the elastic connecting head will expand outward in the radial direction, causing the tips of each petal to contact the ground at an acute angle, thereby further enhancing grip and anti-slip performance.

[0016] Furthermore, as described above, the cane further comprises: a ring wall disposed around the periphery of the ring and surrounding the bottom surface, and the ring wall extending downward.

[0017] Furthermore, as described above, the cane has a plurality of anti-slip units formed on the bottom surface of the base, which are arranged along the circumferential direction of the base.

[0018] Furthermore, as described above, in the cane, each of the anti-slip units on the lower plate is a groove.

[0019] Furthermore, as described above, in the cane, each of the anti-slip units on the lower plate is a fin and is elastic.

[0020] Furthermore, as described above, the cane has a plurality of lobes and a central portion, the plurality of lobes being connected to the periphery of the central portion and spaced apart from each other; each of the lobes extends radially outward from the periphery of the central portion and bends along the circumferential direction of the lower portion.

[0021] Furthermore, as described above, the cane has an upper plate with multiple lobes and a central portion. The multiple lobes are connected to the periphery of the central portion and are spaced apart from each other. Each lobe extends radially outward from the periphery of the central portion and bends along the circumferential direction of the upper plate. The bending direction of the multiple lobes of the upper plate is the same as the bending direction of the multiple lobes of the lower plate.

[0022] Furthermore, as described above, the walking stick assembly includes: an outer tube, the upper end of which is the top end of the walking stick assembly, and a first fastening portion disposed on the outer tube; and an inner rod, which is movably inserted into the outer tube, the lower end of which is the bottom end of the walking stick assembly, and a second fastening portion disposed on the lower end of the inner rod; the first fastening portion and the second fastening portion are detachably engaged with each other, thereby fixing the inner rod within the outer tube.

[0023] Furthermore, as described above, the walking stick assembly further includes: a limiting member disposed on the outer tube and movable along the length of the outer tube; a locking member disposed on the limiting member, the locking member fixing the position of the limiting member relative to the outer tube; and an abutment member fixed to the inner rod and movable with the inner rod relative to the outer tube, the abutment member being separable from the limiting member, thereby limiting the movement distance of the inner rod relative to the outer tube.

[0024] Furthermore, as described above, the cane assembly further includes: a fixing member movably inserted through the wall of the outer tube, one end of the fixing member being detachably inserted through the abutment member, thereby fixing the length of the inner rod protruding from the outer tube.

[0025] Furthermore, as described above, the cane includes a body having: a curved portion that is U-shaped and has two arms; a connecting portion that is connected to one of the arms of the curved portion and to the top of the cane assembly; and a grip strap that is connected at both ends to the two arms of the curved portion respectively.

[0026] Furthermore, as described above, the cane has a mounting hole through which two openings are formed, located on opposite sides of the handle; and a light-emitting element disposed in the mounting hole.

[0027] Furthermore, as described above, the cane further has two lamp covers that can be detachably disposed over the two openings of the mounting hole.

[0028] Furthermore, as described above, the cane further includes a heater disposed on the handle.

[0029] Furthermore, as described above, the cane has a protrusion on the lower plate that is located in the center of the bottom surface and protrudes downward. Attached Figure Description

[0050] Please refer to the following first. Figures 1 to 3 The first embodiment of the walking stick proposed by this utility model includes a base assembly 10, a walking stick body assembly 20, and a handle 30. The walking stick body assembly 20 has a top end 201 and a bottom end 202, the base assembly 10 is disposed at the bottom end 202 of the walking stick body assembly 20, and the handle 30 is disposed at the top end 201 of the walking stick body assembly 20.

[0051] Please refer to Figures 4 to 6 The base assembly 10 has an upper plate 11 and a lower plate 12. The upper plate 11 has an upper surface and a lower surface opposite each other, and the upper plate 11 is connected to the bottom end 202 of the pole assembly 20 above the upper surface. Similarly, the lower plate 12 also has an upper surface and a lower surface opposite each other. The lower plate 12 is elastic, and a plurality of anti-slip units 123 are formed on the bottom surface of the lower plate 12. The upper plate 11 is connected to the top surface of the lower plate 12.

[0052] Specifically, the upper plate 11 has a central portion 111, a plurality of petals 112, and a plurality of connecting members 113. The petals 112 are connected to the periphery of the central portion 111 and arranged circumferentially, with the petals 112 spaced apart from each other. In this embodiment, the plurality of connecting members 113 are respectively disposed on the plurality of petals 112 and connected to the underside of the upper plate 11, but are not limited thereto.

[0053] Each petal 112 extends radially outward from the periphery of the central portion 111 and bends along the circumferential direction of the upper plate 11. In this embodiment, the width of the end of each petal 112 away from the central portion 111 is greater than the width of the end connected to the central portion 111. In contrast, the width of the interval between two adjacent petals 112 at the end away from the central portion 111 is smaller than the width at the end closer to the central portion 111.

[0054] Each connector 113 has a connecting rod 1131 and a connecting head 1132. One end of the connecting rod 1131 is connected to the lower part of the upper plate 11, and the connecting head 1132 is connected to the other end of the connecting rod 1131. Specifically, the outer diameter of the connecting head 1132 is larger than the outer diameter of the connecting rod 1131. In this embodiment, the connecting head 1132 is elastic and forms multiple lobes 1133, which are spaced apart from each other and extend downward. Because the connecting head 1132 is elastic, the distance between the multiple lobes 1133 can change with the applied external force. In this embodiment, the connecting head 1132 is spherical and has a cross-shaped groove to form four lobes 1133, but it is not limited to this. Furthermore, in this embodiment, the upper plate 11 can be detachably coupled to the lower plate 12 by means of the coupling 113, but this is not a limitation. The coupling method of the upper plate 11 and the lower plate 12 can be adjusted according to the needs, or the form of the coupling 113 can also be adjusted according to the needs.

[0055] Please refer to Figures 3 to 6 The lower plate 12 is attached to the upper plate 11 with its top surface facing downwards, and each anti-slip unit 123 is located on the bottom surface and arranged along the circumferential direction of the lower plate 12. In this embodiment, the lower plate 12 has multiple connecting holes 124 formed through it, and multiple connecting parts 113 of the upper plate 11 are respectively disposed in the connecting holes 124 of the lower plate 12, thereby allowing the upper plate 11 and the lower plate 12 to be separably engaged with each other. Specifically, the connecting rod 1131 of each connecting part 113 is relatively movable and passes through one of the connecting holes 124, while the connecting head 1132 protrudes from the bottom surface of the lower plate 12 and can abut against the periphery of the downward-facing opening of the connecting hole 124.

[0056] In this embodiment, each anti-slip unit 123 of the lower plate 12 is a groove, and they are arranged along the circumferential direction of the lower plate 12 to form a ring-shaped groove. In this embodiment, the anti-slip units 123 on the bottom surface of the lower plate 12 can form multiple concentrically arranged ring grooves. The lower plate 12 of this invention is elastic, so that it can deform in accordance with the direction of force after being pressed. It is preferably made of polyethylene (PE) material to obtain the effects of being inexpensive, easy to produce, and wear-resistant, but it is not limited thereto. In this embodiment, the lower surface of the upper plate 11 is a concave surface, and it and the concave top surface of the lower plate 12 surround each other to form a space, which can serve as a movement space when the lower plate 12 is compressed and deformed. Furthermore, when the base assembly 10 contacts the ground and presses down, the arrangement of the ring grooves provides displacement space for the internal volume of the lower plate 12 during deformation, which can reduce the resistance of the lower plate 12 under pressure and deformation, making it easier to deform and more conform to the shape of the ground.

[0057] Furthermore, in this embodiment, the lower plate 12 of the present invention may further have a central portion 121 and a plurality of petals 122. A through hole 1211 is formed through the center of the central portion 121, thereby making the lower plate 12 more stable when in contact with the ground. The through hole 1211 itself can also serve as a reserved space to facilitate the deformation of the lower plate 12 under stress. The petals 122 are connected to the periphery of the central portion 121 and are spaced apart from each other. Each petal 122 extends radially outward from the periphery of the central portion 121 and bends along the circumferential direction of the lower plate 12. Similar to the upper plate 11, in this embodiment, the width of the end of each petal 122 away from the central portion 121 is greater than the width of the end connected to the central portion 121; relatively speaking, the width of the interval between two adjacent petals 122 at the end away from the central portion 121 is smaller than the width at the end closer to the central portion 121.

[0058] In this embodiment, the upper plate 11 is also elastic, and the bending direction of the petals 112 of the upper plate 11 is the same as the bending direction of the petals 122 of the lower plate 12. The number of petals 112 of the upper plate 11 and the number of petals 122 of the lower plate 12 are also the same. This allows the upper plate 11 to conform to the deformation of the lower plate 12, so that the deformation of the lower plate 12 is not limited by the configuration of the upper plate 11. In this embodiment, the upper plate 11 and the lower plate 12 can be the same in size and material. In addition to the connecting member 113, the connecting hole 124, and the through hole 1211 located in the center 121 of the lower plate 12, the shapes of the upper plate 11 and the lower plate 12 can also be the same. This is beneficial to the overall smoothness of the deformation of the base assembly 10, but it is not a limitation.

[0059] Please refer to the following: Figure 3 , Figure 6 ,and Figure 7The cane assembly 20 has a top end 201 and a bottom end 202, and is disposed between the handle 30 and the base assembly 10. Specifically, in this embodiment, the cane assembly 20 may include an outer tube 21 and an inner rod 22, with the outer rod being movably inserted into the outer tube 21. The outer tube 21 has a top end and a bottom end, wherein the top end of the outer tube 21 is the top end 201 of the cane assembly 20. A first fastening part 211 is disposed on the outer tube 21. In this embodiment, the first fastening part 211 is a groove, which is recessed into the outer surface of the outer tube 21 and located at the bottom end of the outer tube 21.

[0060] The inner rod 22 is movably inserted into the outer tube 21. Similarly, the inner rod 22 has an upper end and a lower end, and the lower end of the inner rod 22 is the bottom end 202 of the cane assembly 20. A second fastening part 221 is provided at the lower end of the inner rod 22. The first fastening part 211 and the second fastening part 221 are detachably engaged with each other, thereby fixing the inner rod 22 inside the outer tube 21. Specifically, in this embodiment, the inner rod 22 can move relative to the outer tube 21 to extend or retract. When the inner rod 22 is retracted into the outer tube 21 and the first fastening part 211 and the second fastening part 221 are engaged with each other, the inner rod 22 can be fixed inside the outer tube 21 for easy storage by the user.

[0061] Please refer to Figure 7 and Figure 8 In this embodiment, the second fastening part 221 is a latching member, one end of which is connected to the lower end of the inner rod 22, and the other end forms a hook 2211, which can be detachably fitted into the groove of the first fastening part 211. In this embodiment, the second fastening part 221 is elastic, and the top surface of the hook 2211 is a downward and inward inclined slope. Therefore, when the user wants to close the inner rod 22, they can press against the ground and down the outer tube 21. The inclined direction of the top surface of the hook 2211 can follow the downward sliding direction of the outer tube 21 and elastically expand outward until it aligns with the first fastening part 211 and returns to its shape for smooth fastening. When the user wants to pull out the inner rod 22, they can use their hand or foot to pry open the hook 2211 of the second fastening part 221.

[0062] Please refer to Figure 7 , Figure 8 , Figure 14 ,and Figure 15In this embodiment, the cane assembly 20 may preferably further include a limiting member 23, a locking member 24, and a stop member 25, thereby limiting the movement distance (i.e., extension length) of the inner rod 22 relative to the outer tube 21. The limiting member 23 is disposed on the outer tube 21 and can move along the length direction of the outer tube 21. The locking member 24 is disposed on the limiting member 23 and is used to fix the position of the limiting member 23 relative to the outer tube 21. The stop member 25 is fixed to the inner rod 22 by means of a pin through connection and can move with the inner rod 22 relative to the outer tube 21. The stop member 25 can be detachably abutted against the limiting member 23. On the other hand, if the components of the cane assembly 20 in this embodiment are combined with the base assembly 10, which includes the upper plate 11, the connecting member 113, the lower plate 12, and the connecting hole 124, and grouped by function, they can be divided into a moving module and a limiting module. The moving module moves relative to the limiting module, and the limiting module restricts its range of movement, thereby allowing the user to remember the length they are used to. This ensures that the length of the moving module is the same every time it is unfolded and used, without having to readjust the length each time, which is more convenient. In addition, the extended length can be easily locked or unlocked for quick use and folding. Specifically, the moving module includes an inner rod 22, a second fastening part 221, abutment 25 and its extension 251, and the entire base assembly 10, while the limiting module includes a limiting member 23, a locking member 24, a fixing member 26, and an elastic mechanism 27. In other words, the movement of the inner rod 22, the second fastening part 221, the abutment 25 and its extension 251, and the entire base assembly 10 will be limited by the limiting member 23, the locking member 24, the fixing member 26, and the elastic mechanism 27.

[0063] In this embodiment, the outer tube 21 further includes a slide rail 212 extending along the length of the outer tube 21. The limiting member 23 is a slider movably disposed within the slide rail 212. The locking member 24 is a screw in this embodiment, passing through the limiting member 23. When tightened, the locking member 24 clamps together with the limiting member 23 on the slide rail 212, thereby fixing the position of the limiting member 23. The abutment member 25 is disposed at the upper end of the inner rod 22 and protrudes outward to the slide rail 212, located between the limiting member 23 and the upper end of the outer tube 21. When the inner rod 22 moves relative to the outer tube 21, the abutment member 25 also moves along the slide rail 212. Therefore, the limiting member 23 restricts the movable distance of the abutment member 25 within the slide rail 212, further limiting the maximum length of the inner rod 22 extending beyond the outer tube 21. This allows the user to memorize the length most suitable for their use within the cane assembly 20.

[0064] Preferably, the cane assembly 20 may further include a fixing member 26, which is movably inserted through the wall of the outer tube 21. One end of the fixing member 26 is detachably inserted through the abutment member 25, thereby fixing the length of the inner rod 22 protruding from the outer tube 21. In this embodiment, the fixing member 26 is a pin that passes through the limiting member 23 and has an elastic mechanism 27 that tends to push the fixing member 26 inward. In addition, specifically, the abutment member 25 extends downward with an extension 251, and a blind hole 252 is recessed in the extension 251. When the abutment member 25 abuts against the limiting member 23, the blind hole 252 of the extension 251 is exactly aligned with the fixing member 26. At this time, the elastic mechanism 27 pushes one end of the fixing member 26 into the blind hole 252, so that the inner rod 22 will not move relative to the outer tube 21, thereby fixing the protruding length of the inner rod 22 relative to the outer tube 21, but this is not a limitation. Conversely, when the user wants to retract the cane assembly 20, they only need to pull the retaining member 26 outwards to push the inner rod 22 upwards and retract it into the outer tube 21. For further details, please refer to... Figure 3 and Figure 15 In this embodiment, the part of the abutment 25 that abuts against the limiting member 23 and the extension 251 are separable elements, and the aforementioned elements are fixed to the upper end of the inner rod 22 by means of a pin.

[0065] Please refer to the following: Figures 1 to 3 , Figure 11 ,and Figure 12 The handle 30 is connected to the top end 201 of the cane assembly 20, specifically to the upper end of the outer tube 21. In this embodiment, the handle 30 includes a body 31 and a gripping strap 32. The body 31 has a curved portion 311 and a connecting portion 312. The curved portion 311 is U-shaped and has two arms 3111, while the connecting portion 312 is connected to one of the arms 3111 of the curved portion 311 and to the top end 201 of the cane assembly 20. The two ends of the gripping strap 32 are respectively connected to the inner edges of the two arms 3111 of the curved portion 311. In this embodiment, the gripping strap 32 is elastic, thereby facilitating the user to hold the handle 30 of this invention in different ways to meet different usage needs, such as use in different situations, or the user wanting to use different gripping gestures due to wrist or other injuries, but is not limited thereto.

[0066] In addition, in this embodiment, the support arm 3111 of the curved part 311, which is not connected to the connecting part 312, is slightly inclined downward and extends to form a handle 313, which is ergonomic and convenient for users to hold and apply force. It is also convenient for users to hang this utility model, for example, it can be hung on a door handle or table edge for storage and reuse.

[0067] Furthermore, the handle 30 of this invention may also include a heater 33, a mounting hole 34, a light-emitting element 35, and two lamp covers 36. Specifically, the heater 33 is disposed on the body 31 of the handle 30, thereby keeping the handle 30 warm in cold weather, thereby promoting blood circulation in the user's hands and reducing the risk of falls due to insufficient grip strength caused by muscle stiffness caused by cold. In this embodiment, the heater 33 is made of zirconium oxide and is disposed on the curved portion 311 of the body 31, but is not limited thereto.

[0068] A mounting hole 34 is formed through the handle 30, creating two openings 341. These two openings 341 are located on opposite sides of the handle 30, and a light-emitting element 35 is disposed within the mounting hole 34. Specifically, the two openings 341 of the mounting hole 34 are located on the front and rear sides of the handle 30. When the light-emitting element 35 emits light, light is emitted from the two openings 341, providing illumination and warning functions simultaneously. In this embodiment, the light-emitting element 35 is a light-emitting diode (LED), but this is not a limitation. Two lamp covers 36 are detachably disposed over the two openings 341 of the mounting hole 34. This allows the user to close the opening 341 on the side that does not require illumination when only illumination on one side is needed.

[0069] Please refer to Figures 10 to 13 In this embodiment, a control circuit 37 is provided inside the handle 30, and the handle 30 may further have a power switch 38 and a charging port 39. The control circuit 37 is electrically connected to the heater 33, the light-emitting element 35, the power switch 38, and the charging port 39. The control circuit 37 can be used to control the heater 33, for example, to control whether it heats up or its heating power; the control circuit 37 can also be used to control the lighting mode of the light-emitting element 35, for example, to control whether it flashes or its flashing frequency. The power switch 38 can be used to activate the control circuit 37. In this embodiment, the power switch 38 is a multi-stage switch, allowing the user to press the power switch 38 different times to simultaneously turn on the heater 33 and the light-emitting element 35, or only turn on the heater 33 or only turn on the light-emitting element 35, or disconnect the power. The user can charge the device through the charging port 39. In this embodiment, a USB Type-C charging port 39 is used, but this is not a limitation.

[0070] When using this utility model, please refer to Figure 7 and Figure 8The user can first adjust the cane assembly 20 to a suitable length, then use the locking member 24 to lock the limiting member 23 to memorize this suitable length, so that it does not need to be readjusted for future reuse; then use the fixing member 26 to fix the length of the inner rod 22 extending relative to the outer tube 21. The user then holds the handle 30 and places the base assembly 10 in contact with the ground, thus using this invention to support body weight and assist walking. Please see... Figure 3 and Figure 10 Users can grip the handle 30 in various ways to use this invention. For example, they can hold the handle 313 of the curved portion 311 of the main body 31 to assist walking, similar to using a walking stick; or they can support their palm against the part between the two arms 3111 of the curved portion 311 and pull the grip strap 32 with their fingers to use this invention in a manner similar to a walking stick. The aforementioned two methods are merely examples. Users can choose the gripping method according to their actual needs or physical condition. The handle 30 of this invention simply provides diverse gripping methods.

[0071] Please see Figures 16 to 20 The base assembly 10A of the second embodiment of this utility model is largely the same as that of the first embodiment. The upper plate 11 is connected to the lower plate 12A by a connecting member 113. The main difference is the form of the lower plate 12A.

[0072] In this embodiment, the lower plate 12A of the base assembly 10A further has an annular wall 125A, which is disposed at the periphery of the lower plate 12A and extends downward, and a protrusion 126A is formed at the center of the bottom surface of the lower plate 12A, which protrudes downward. In this embodiment, the protrusion 126A is approximately bell-shaped, but is not limited thereto. In addition, in this embodiment, each anti-slip unit 123A of the lower plate 12A is an elastic fin, one end of which is connected to the bottom surface and the other end extends downward.

[0073] Furthermore, similarly, such as Figure 18 and Figure 19 As shown, the lower plate 12A in this embodiment can also have a central portion 121A and multiple petal portions 122A, similar to the first embodiment. The petal portions 122A are connected to the periphery of the central portion 121A and are spaced apart from each other. Each petal portion 122A extends radially outward from the periphery of the central portion 121A and bends along the circumferential direction of the lower plate 12A. This allows the lower plate 12A to have more random contact points when it is pressed against the ground, thereby increasing grip, but it is not limited to this. Multiple connecting holes 124A are formed through the petal portions 122A, and the connecting rod 1131 of the connecting member 113 is movably inserted into the connecting hole 124A. The connecting head 1132 abuts against the downward-facing opening of the connecting hole 124A.

[0074] Because the lower plate 12A of this embodiment has an annular wall 125A, it can more quickly stabilize its center of gravity when the base assembly 10A just touches the ground, thus reducing the risk of tipping over and minimizing the risk of the user falling. Furthermore, when the user does not need to use this invention temporarily but cannot find a place to hang or lean it against, the base assembly 10A of this embodiment, due to the annular wall 125A, can stand upright on the ground without support, making it convenient for the user to temporarily place or store it.

[0075] Furthermore, when the base assembly is subjected to downward pressure, causing the lower plate 12A to deform and its bottom surface to approach the ground, the protrusion 126A located in the center of the bottom surface of the lower plate 12A can support the ground, thereby providing the lower plate 12A as a support during various deformations to improve stability. In this embodiment, the anti-slip unit 123A is in the form of a fin, which will also deform according to the pressure on the ground after contacting the ground to help increase grip and enhance the anti-slip effect.

[0076] Please see Figures 3 to 6 When the base assembly 10 of this invention contacts the ground and is subjected to downward pressure from the user, the elastic material of the lower plate 12 of the base assembly 10 allows it to deform according to the force, thus contacting the ground with a larger area. This also allows the connecting head 1132 of the connecting member 113 of the upper plate 11 to contact the ground. The perforation 1211 and the annular groove in the center 121 of the lower plate 12 provide deformation space, allowing the lower plate 12 to easily change shape and better adapt to various ground shapes. Furthermore, in this embodiment, the material, shape, and size of the upper plate 11 are the same as the lower plate 12, allowing the upper plate 11 to conform to the shape changes of the lower plate 12 without restricting the deformation of the lower plate 12. Therefore, the entire base assembly 10 can better conform to the ground and adapt to various terrains. In addition, this embodiment uses PE material for both the lower plate 12 and the upper plate 11 of the base assembly 10, making it easy to process, wear-resistant, and inexpensive.

[0077] Furthermore, when the bottom of the base 12 deforms and contacts the ground, the curved petals 122 can deform in the circumferential direction. Combined with the multiple protrusions of varying heights formed by the annular grooves of the anti-slip unit 123 on the bottom surface, this achieves maximum random elasticity and random protrusion points. Moreover, the petals 122 deforming in the circumferential direction can generate torque. Therefore, the base assembly 10 of this invention can achieve strong grip. In addition, please refer to... Figure 3 and Figure 6The base assembly 10 of this invention is locked to the bottom end 202 of the cane assembly 20 with a single screw, making it easy to replace when worn down after prolonged use. Furthermore, when the lower plate 12 is deformed under pressure, the connecting head 1132 of the connecting member 113 of the upper plate 11 will also contact the ground. The connecting head 1132, with its multiple lobes 1133, increases friction with the ground, further enhancing grip.

[0078] When the user wants to store this utility model, simply pull up the fixing member 26 to retract the inner rod 22 into the outer tube 21 until the second fastening part 221 automatically engages with the first fastening part 211. Conversely, when using it, simply release the engagement between the second fastening part 221 and the first fastening part 211 to pull out the inner rod 22. Therefore, this utility model is easy to store and open. In addition, as mentioned earlier, if the user has memorized the suitable length using the locking limit member 23, then simply pull out the inner rod 22 until the abutment member 25 abuts against the limit member 23, and the fixing member 26 is automatically pushed into the blind hole 252 by the elastic mechanism 27 to secure it, without having to readjust and find the suitable length. In addition, the heater 33 of this invention can warm the handle 30, making it easier to use in cold weather and reducing the risk of falling due to loss of hand strength caused by poor blood circulation. Users can also selectively make the light-emitting element 35 illuminate forward, backward, or both simultaneously to provide lighting or warning functions, illuminating the road or alerting oncoming vehicles to ensure user safety. The aforementioned light-emitting element 35 and heater 33 are electrically connected to the control circuit 37, allowing users to control its use via the power switch 38 and charge it via the charging port 39. When not in use, the user can hang the invention on a doorknob or table edge via the handle 30 for easy storage; or, in the second embodiment of this invention, since the lower plate 12A has a ring wall 125A, it can be left to stand naturally.

[0079] The advantages of this invention are that the upper plate 11 and lower plate 12 of the base assembly 10 are connected to each other by a connecting member 113 and a connecting hole 124. The connecting rod 1131 of the connecting member 113 passes through the connecting hole 124, so the lower plate 12 can move slightly relative to the upper plate 11, providing a margin of space. In addition, the lower plate 12 itself is elastic, so it can better conform to the terrain and increase the grip area. Furthermore, when the lower plate 12 is deformed, the connecting head 1132 of the connecting member 113 can also contact the ground. Since the connecting head 1132 contains multiple petals 1133, these multiple petals 1133 can also contact the ground. There are gaps between the multiple petals 1133 of the same connecting head 1132, and the connecting head 1132 is elastic. Therefore, the connecting head 1132 can also help the base assembly 10 increase the grip after contacting the ground and improve the anti-slip effect. In other words, the base assembly 10 can be freely coupled to the upper plate 11 and lower plate 12 via a coupling 113. The tightness of the connection between the upper plate 11 and lower plate 12 can be changed by varying the length of the coupling rod 1131. For example, if the coupling rod 1131 is shorter, the connection between the upper plate 11 and lower plate 12 is tighter; conversely, if the coupling rod 1131 is longer, the base assembly 10 forms a looser connection, providing room for deformation. Furthermore, if combined with the multi-lobed design of the elastic coupling head 1132, when the user applies pressure and the base assembly 10 touches the ground, the lobes 1133 of the multi-lobed coupling head 1132 will open outward in the radial direction, so that the tip of each lobe 1133 contacts the ground at an acute angle, thereby further increasing the grip. In summary, compared with traditional walking sticks, this invention is applicable to various ground surfaces and provides stronger grip, allowing users to move around more diverse and unrestricted.

[0080] Furthermore, this invention allows users to easily set their preferred length, and the snap-fit ​​mechanism makes the cane assembly 20 easy to fold and unfold, facilitating use. Moreover, the cane of this invention allows users to grip it in multiple ways to suit different usage occasions and user conditions, and the light-emitting element 35 and heater 33 also enhance user safety while walking. This invention expands the user's usability, helping them reach more diverse locations and improving walking safety.
