Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, and in particular to a folding cane with a button concealed inside. Background Technology

[0002] As an assistive device, walking sticks are widely used in outdoor sports such as mountaineering, hiking, and skiing, as well as to assist the elderly in walking.

[0003] To improve the portability of walking sticks, most existing walking sticks adopt a multi-section folding structure, including a handle and multiple sections of the cane tube. Each section is connected by a steel wire rope. The first section of the cane tube is fixed inside the handle and is telescopically connected to the second section of the cane tube. The remaining sections of the cane tube are connected to the second section of the cane tube end to end through connectors. When assembling the walking stick, hold the handle with one hand and pull down the second section of the cane tube with the other hand. When the button inside the second section of the cane tube abuts against the end of the first section of the cane tube, the steel wire rope is taut inside each section of the cane tube, thus locking the sections of the cane tube together.

[0004] However, when using the aforementioned cane, the button is located on the outside of the cane, posing a risk of accidental contact. This could cause the cane tubes to be accidentally unlocked during use. Furthermore, when folding the cane, the button needs to be pressed with a finger, resulting in a poor tactile experience. Additionally, since the length of each cane tube is fixed after assembly, the length of the cane cannot be adjusted as needed. Summary of the Invention

[0005] To address the shortcomings of the existing technology, this utility model provides a folding cane with a built-in button, which is unlocked without manual pressing, eliminating the risk of accidental contact, and allowing for height adjustment as needed. It is simple to operate and highly applicable.

[0006] The technical solution of this utility model is as follows: a button-integrated folding cane, comprising at least three sections, wherein a handle is fixed to the first section, a cane tip is fixed to the last section, a second section is inserted into the first section to form a telescopic unit, and the remaining sections are connected end-to-end to the second section via connectors to form a folding unit. The telescopic unit contains a first pull cord, the folding unit contains a second pull cord, and the telescopic unit has a locking assembly for locking the telescopic position of the second section. The second section contains a sliding seat that moves axially. The lower end of the first pull cord and the upper end of the second pull cord are both connected to the sliding seat. The upper end of the pull cord is connected to the first section of the cane via a plug, and the lower end of the second pull cord is connected to the last section of the cane via an elastic component. The sliding seat has an elastic buckle fixed on the side facing the plug. The upper end of the second section of the cane has a locking part that cooperates with the elastic buckle to restrict the elastic buckle from moving downward and keeping it in a locked state. In the locked state, the second pull cord is tightened and pulls the elastic component to deform. The lower end of the plug has an unlocking part that cooperates with the elastic buckle to drive the elastic buckle out of the locking part and keep it in an unlocked state. In the unlocked state, the elastic component is reset and drives the sliding seat to move away from the plug. The elastic latch, acting as a button, remains inside the cane tube in both the locked and unlocked states, eliminating the risk of accidental contact. When folding, simply open the locking assembly, retract the second section of the cane tube upwards, and once the elastic latch engages with the unlocking part of the end cap, it separates from the locking part. The elastic assembly then resets, causing the elastic latch to retract into the second section of the cane tube, allowing the folding unit to be folded and separated. The entire unlocking process is convenient and simple. Furthermore, the telescopic unit, composed of the first and second sections of the cane tube, can extend and retract after the elastic latch is locked, allowing users to select the appropriate cane length according to their needs, effectively improving its versatility.

[0007] The upper end of the second section of the cane is fixed with an inner sleeve, the upper end of which forms the locking part, and the elastic buckle has a stepped surface that mates with the upper end of the inner sleeve.

[0008] The lower end of the plug is formed with an inner ring portion, and the lower end of the inner ring portion forms the unlocking portion. The elastic buckle has a sloped surface that mates with the lower end of the inner ring portion.

[0009] The elastic buckle includes a metal spring and a buckle body fixed to the upper end of the metal spring. The lower end of the metal spring is fixed to the sliding seat. The stepped surface is located on the connection surface between the buckle body and the metal spring. The sloped surface is located at the top of the buckle body and slopes upward toward the center of the sliding seat.

[0010] The inner ring is an inner cylindrical surface, and the inner diameter of the inner cylindrical surface is not greater than the inner diameter of the inner bushing.

[0011] The lower end of the inner liner is an inner conical surface whose dimensions gradually widen from top to bottom.

[0012] The plug-in connector includes a connecting tube and a guide tube. The connecting tube is fixed inside the rear section of the cane tube. One end of the guide tube is fixed inside the connecting tube via the plug-in part. The outer surface of the guide tube has an outer conical surface that smoothly transitions to the surface of the connecting tube.

[0013] The plug has a first through hole in the middle. The upper end of the first pull rope passes through the first through hole and then contacts the plug through a knot. The sliding seat has a second through hole and a third through hole side by side. The lower end of the first pull rope passes through the second through hole and then contacts the sliding seat through a knot. The upper end of the second pull rope passes through the third through hole and then contacts the sliding seat through a knot.

[0014] The elastic component includes a fixed base, a spring member, and a stop member. The fixed base is fixed inside the end section of the cane tube. The spring member and the stop member are sequentially arranged below the fixed base. The lower end of the second pull rope passes through the fixed base and the spring member in sequence and is connected to the stop member.

[0015] The locking assembly includes a connecting sleeve, a locking ring fixed to one end of the connecting sleeve, a connecting bolt passing through both sides of the opening of the locking ring, a connecting nut connected to the threaded portion of the connecting bolt, and a cam handle rotatably connected to the head of the connecting bolt. The connecting sleeve is fixed to the lower end of the first section of the cane tube, and the locking ring is sleeved on the outside of the second section of the cane tube and locks and fixes the second section of the cane tube under the rotation of the cam handle.

[0016] In summary, the present invention has the following main advantages:

[0017] This invention divides the cane tube into telescopic and folding units. A first and second pull rope are respectively installed within each unit, connected by a sliding seat. An elastic buckle on the sliding seat serves as a button for assembling and folding the cane. This button remains inside the cane tube in both locked and unlocked states, eliminating the risk of accidental contact. After locking the folding unit, the position of the second cane tube within the first cane tube can be adjusted using a locking assembly, thereby adjusting the overall length of the cane to suit user needs. To fold the cane, simply open the locking assembly, retract the second cane tube upwards until the elastic buckle engages with the unlocking part of the end cap, and then disengages from the locking part. The elastic assembly then retracts the buckle back into the second cane tube, allowing the second pull rope to be pulled to fold the cane tubes. The entire unlocking process is simple and quick, requiring no finger pressure. Attached Figure Description

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the following description, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0026] Furthermore, in this utility model, directional terms such as "upper," "lower," "left," and "right" may be defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms can be relative concepts, used for relative description and clarification, and can change accordingly based on the orientation of the components in the accompanying drawings.

[0027] like Figure 1 As shown, this utility model provides a button-concealed folding cane, including at least three sections of cane tube. An EVA handle 1 is fixed to the outside of the first section 3, and a cane tip 2 is fixed to the lower end of the last section 6. The second section 4 is inserted into the first section 3 to form a telescopic unit. The remaining sections are connected end-to-end to the second section 4 via connectors 14 to form a folding unit. Specifically, in this design, a four-section cane is selected, consisting of, from top to bottom, the first section 3, the second section 4, the third section 5, and the last section 6. The third section 5 and the second section 4, and the last section 6 and the third section 5, are adjacent to each other via connectors 14. To reduce the weight of the cane while ensuring its strength, each section is made of carbon fiber. Figure 3 As shown, the plug-in connector 14 includes a connecting tube 1401 and a guide tube 1402. The connecting tube 1401 is made of aluminum alloy, and the guide tube 1402 is made of PVC. The connecting tube 1401 and the guide tube 1402 have internal channels that are coaxially connected to each section of the cane tube. The connecting tube 1401 is fixed inside the next section of the cane tube (i.e., the connecting tube 1401 located between the third section of the cane tube 5 and the second section of the cane tube 4 is fixed inside the third section of the cane tube 5, and the connecting tube 1401 located between the last section of the cane tube 6 and the third section of the cane tube 4 is fixed inside the third section of the cane tube 5). The connecting tube 1401 between tubes 5 is fixed inside the last section of the cane tube 6. A limiting step is formed in the middle of the connecting tube 1401 to limit the length of the connecting tube 1401 inserted into the next section of the cane tube. One end of the guide tube 1402 is fixed inside the connecting tube 1401 via the insertion part 1403. All of the above fixing methods are achieved by adhesive bonding. The outer surface of the guide tube 1402 has an outer conical surface that smoothly transitions to the surface of the connecting tube 1401, which provides guidance for the insertion of the rear cane tube into the front cane tube.

[0028] like Figure 2 As shown, the telescopic unit (first section of the cane tube 3 and second section of the cane tube 4) is equipped with a first pull rope 7, and the folding unit (from the second section of the cane tube 4 to the last section of the cane tube 6) is equipped with a second pull rope 8. The telescopic unit is equipped with a locking component 13 for locking the telescopic position of the second section of the cane tube 4. Specifically, as shown... Figure 3As shown, the locking assembly 13 includes a connecting sleeve 1301, a locking ring 1302 formed on one end of the connecting sleeve 1301, a connecting bolt 1303 passing through both sides of the opening of the locking ring 1302, a connecting nut 1304 connected to the threaded portion of the connecting bolt 1303, and a cam handle 1305 rotatably connected to the head of the connecting bolt 1303 via a pin shaft 1305. The connecting sleeve 1301 is glued to the lower end of the first section of the cane tube 3, and the locking ring 1302 is sleeved on the... On the outer side of the second cane tube 4, the cam handle 1305 rotates near the locking ring 1302. Under the cam pressing action of the cam handle 1305, the inner diameter of the locking ring 1302 decreases until it is locked and fixed to the outer wall of the second cane tube 4. At this time, the locking assembly 13 completes the locking of the second cane tube position. The cam handle 1305 rotates away from the locking ring 1302, and the locking ring 1302 returns to release the locking of the second cane tube 4. At this time, the second cane tube 4 can freely extend and retract relative to the first cane tube 3.

[0029] like Figure 4 As shown, the second section of the cane tube 4 is provided with a sliding seat 9 that moves axially. The lower end of the first pull rope 7 and the upper end of the second pull rope 8 are connected to the sliding seat 9. The upper end of the first pull rope 7 is connected to the first section of the cane tube 3 via a plug 11, and the lower end of the second pull rope 8 is connected to the last section of the cane tube 6 via an elastic component 12. To facilitate the connection and fixation of the pull ropes, as shown... Figure 2 As shown, the plug 11 has a first through hole 1103 in the middle. The upper end of the first pull rope 7 passes through the first through hole 1103 and then makes contact with the plug 11 through a knot. The sliding seat 9 has a second through hole and a third through hole side by side. The lower end of the first pull rope 7 passes through the second through hole and then makes contact with the sliding seat 9 through a knot. The upper end of the second pull rope 8 passes through the third through hole and then makes contact with the sliding seat 9 through a knot. The first pull rope 7 and the second pull rope 8 are made of high-strength Dyneema wire. Through the knots at their respective ends, they are taut and straight between the plug 11 and the sliding seat 9, and between the sliding seat 9 and the elastic component 12. They can also move within the through hole in a non-taut state, ensuring the freedom of the pull rope.

[0030] The sliding seat 9 is fixed with an elastic buckle 10 on the side facing the plug 11. Specifically, in this solution, the elastic buckle 10 includes a metal spring 1002 and a buckle body 1001 fixed on the upper end of the metal spring 1002. It is worth noting that the buckle body 1001 and the metal spring 1002 are integrally stamped stainless steel parts. The lower end of the metal spring 1002 is fixed on the sliding seat 9. This fixing method can use nylon injection molding material as the sliding seat 9. The sliding seat 9 and the elastic buckle 10 are integrated by injection molding. The connection position of the elastic buckle 10 and the sliding seat 9 is located at the position off-center of the sliding seat 9, so that the buckle body 1001 can move closer to the center of the sliding seat 9 under the action of external force.

[0031] like Figure 4 and Figure 5 As shown in (a), the upper end of the second section of the cane tube 4 has a locking part 1501 that engages with the elastic buckle 10 to restrict the elastic buckle 10 from moving downward and keeping it in a locked state. Since the elastic component 12 is in its natural state, the length of the second pull rope 8 is not sufficient to allow the elastic buckle 10 to reach the position where it engages with the locking part 1501. Therefore, when the elastic buckle 10 reaches the locked position and is in the locked state, the second pull rope 8 is tightened and pulls the elastic component 12 to move towards the end cap 11 (upward movement), causing deformation. Figure 5 As shown in (b), the lower end of the plug 11 has an unlocking part 1102 that cooperates with the elastic buckle 10 to drive the elastic buckle 10 out of the locking part 1501 and put it in the unlocked state. When the elastic buckle 10 is in the unlocked state, as shown in (b), Figure 5 As shown in (c), the elastic component 12 resets and drives the sliding seat 9 to move (downward) in a direction away from the plug 11, so that the elastic buckle 10 retracts into the second section of the cane tube 4.

[0032] The elastic buckle 10 serves as the locking and unlocking button in this solution. Throughout the entire use, the elastic buckle 10 remains inside the cane, eliminating the risk of accidental contact. After locking the folding unit, the length of the telescopic unit, consisting of the first section of the cane tube 3 and the second section of the cane tube 4, can be adjusted via the locking component 13 to customize the cane to suit user needs. During folding, the second section of the cane tube 4 is retracted upwards, causing the elastic buckle 10 to engage with the unlocking part 1102 of the end cap 11 until the elastic buckle 10 separates from the locking part 1501. At this point, under the reset action of the elastic component 12, the elastic buckle 10 is pulled back into the second section of the cane tube 4, thus releasing the locking state of the folding unit and allowing the sections of the cane tube to be folded separately. The entire unlocking process is simple and quick, requiring no finger pressing and causing no discomfort to the fingers.

[0033] like Figure 3and Figure 4 As shown, an inner sleeve 15 is fixed to the upper end of the second section of the cane tube 4. The inner sleeve 15 is made of aluminum alloy and has a boss structure formed on its upper end. The lower end of the inner sleeve 15 is inserted into the inner side of the upper end of the second section of the cane tube 4 and glued in place. The bottom of the boss structure abuts against the end face of the second section of the cane tube 4. At this time, the boss structure forms the locking part 1501 to ensure that the locking part 1501 has sufficient strength and locking mating area. The elastic buckle 10 has a stepped surface 1004 that mates with the upper end of the inner sleeve 15. Specifically, in this solution, the stepped surface 1004 is located on the connecting surface between the buckle body 1001 and the metal spring 1002, and when the stepped surface 1004 is in full contact with the boss structure, such as Figure 4 and Figure 5 As shown in (a), the metal shrapnel 1002 is in its natural state.

[0034] like Figure 2 and Figure 5 As shown, the lower end of the plug 11 is formed with an inner ring portion 1101, and the lower end of the inner ring portion 1101 forms the unlocking portion 1102. The elastic buckle 10 has a sloped surface 1003 that mates with the lower end of the inner ring portion 1101. Specifically, the plug 11 is a PVC cylindrical part with a limiting boss formed at its upper end. The lower end of the plug 11 is inserted into the inner side of the upper end of the first section of the cane tube 3 and glued in place. The bottom of the limiting boss abuts against the upper end face of the first section of the cane tube 3. An annular plate is formed in the middle of its inner cavity. The through hole in the middle of the annular plate is the first through hole 1103. The inner cylindrical surface located below the annular plate is the aforementioned... The inner ring portion 1101, the aforementioned plug part 11 structure, is simple to process and has low purchase cost. Furthermore, the inner diameter of the inner cylindrical surface is not greater than the inner diameter of the inner bushing 15, so that the buckle assembly can be smoothly pulled back into the second section of the cane tube 4 under the reset action of the elastic component 12. The aforementioned slope surface 1003 is located at the top of the buckle body 1001 and is inclined upward in the direction toward the center of the sliding seat 9. Preferably, the buckle body 1001 can be formed into a semi-cylindrical structure to ensure that the buckle body 1001 slides smoothly in the second section of the cane tube 4, and the slope surface 1003 is a wedge-shaped surface formed on the top of the semi-cylindrical structure.

[0035] like Figure 4 As shown, the lower end of the inner sleeve 15 is an inner conical surface with a gradually widening size from top to bottom. After the buckle body 1001 is pulled back into the second section of the cane tube 4, the folding unit is unlocked, and the second pull rope 8 can be pulled freely. During the process of pulling the second pull rope 8, the buckle body 1001 will disengage from the inner sleeve 15. The design of the inner conical surface ensures that the movement of the buckle body 1001 is smoother during this process.

[0036] like Figure 2 and Figure 3As shown, in this scheme, the elastic component 12 includes a fixing seat 1201, a spring 1202, and a stop 1203. The fixing seat 1201 is fixed inside the end section of the cane tube 6. The fixing seat 1201 can be directly selected as an aluminum alloy connecting tube 1401 glued to the upper end of the end section of the cane tube 6. The lower end outlet size of the aluminum alloy connecting tube 1401 is smaller than its internal channel size. The spring 1202 and the stop 1203 are sequentially arranged below the aluminum alloy connecting tube 1401. The lower end of the second pull rope 8 passes through the aluminum alloy connecting tube 1401 and the spring 1202 in sequence and is connected to the stop 1203. More preferably, in order to facilitate the connection of the second pull rope 8 and the elastic component 12, such as Figure 2 As shown, the stop 1203 is a stop ring structure. The lower end of the second pull rope 8 passes through the stop ring and then makes contact with the outer side of the stop ring through a knot.

[0037] When using the assembled staff, such as Figure 1 and Figure 2 As shown, with the cam handle 1305 of the locking assembly 13 in the open state, hold the handle 1 with one hand and the second section of the cane tube 4 with the other hand and pull down. The guide tube 1402 at the upper end of the third section of the cane tube 5 is inserted into the second section of the cane tube 4, and the guide tube 1402 at the upper end of the last section of the cane tube 6 is inserted into the third section of the cane tube 5. The vertical connection of the folding unit is completed. Since the length of the first pull rope 7 is fixed, the sliding seat 9 remains in its original position. As the folding unit moves down, the second pull rope 8 is taut and tightened. The sliding seat 9 slides upward relative to the second section of the cane tube 4 within the second section of the cane tube 4. At this time, the spring 1202 is compressed. Until the stepped surface 1004 of the buckle body 1001 is precisely engaged with the boss structure end face of the inner liner 15, the folding unit is locked into place. At this point, the user can adjust the second cane tube 4 to a suitable position according to their height (gradation marks can be set on the outer wall of the second cane tube 4), press down the cam handle 1305, and the locking ring 1302 locks and fixes the second cane tube at this position. After use, open the cam handle 1305 and move the entire folding unit upwards inside the first cane tube 3. Due to the presence of the top slope surface 1003 of the buckle body 1001, such as... Figure 5 As shown in (a), when the sloped surface 1003 of the buckle body 1001 touches the lower end of the plug 11, the buckle body 1001 is pressed and shifted towards the center, as shown in (a). Figure 5 As shown in (b), the stepped surface 1004 of the buckle body 1001 disengages from the boss structure end face of the inner bushing 15, as... Figure 5 As shown in (c), under the reset action of the spring 1202, the sliding seat 9 is pulled down by the second pull rope 8, so that the buckle body 1001 is retracted into the second section of the cane tube 4. At this time, the folding unit is unlocked, and the last section of the cane tube 6 can be pulled to disengage the last section of the cane tube 6, the third section of the cane tube 5, and the second section of the cane tube 4 from each other and fold.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the principles of this utility model should be included within the protection scope of this utility model.
