Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, and in particular to a foldable column and a treadmill. Background Technology

[0002] Modern treadmills not only need to meet users' basic running needs, but also their needs for convenient operation and storage. Therefore, the functions of modern treadmills are gradually developing towards greater user-friendliness, multi-functionality, user comfort, and reasonable storage.

[0003] Given the limited indoor living space, many fitness enthusiasts are deterred from using bulky treadmills. Therefore, based on the structural characteristics of treadmills and in order to reduce the indoor space they occupy, many foldable treadmill models have emerged on the market, providing consumers with more options for where to place their treadmills and winning widespread praise from consumers.

[0004] However, the folding function of treadmills is still relatively simple at present, often only the running board or handrail can be folded. There are few treadmills with foldable uprights. In addition, since the uprights are often quite tall, the folding operation of the uprights is not smooth enough, or the folding mechanism of the uprights takes up a lot of space. Utility Model Content

[0005] The purpose of this utility model is to provide a foldable column and a treadmill, so as to solve the problems that there are few foldable structures for columns in the prior art and that the folding operation of columns is not smooth enough. The specific technical solution is as follows: In one aspect, this utility model provides a foldable column, including a base and a column rotatably connected to the base. The column includes a first column and a second column connected to each other at a preset first angle. The end of the first column is rotatably connected to the base and is provided with a pin assembly at the end. The pin assembly can extend or retract from the end of the first column along the axial direction of the first column. A limiting block is provided on the base, and a first groove is provided on the limiting block. The pin assembly rotates along the first groove, and a second groove is provided on the first groove. The pin assembly can be inserted into the second groove to make the column unfolded. The first end of the limiting block is away from the folding direction of the column, and the end face of the first end of the limiting block is inclined downward. The pin assembly abuts against the end face of the limiting block to make the column fold and the second column is spaced apart from the base.

[0006] Furthermore, the second groove is provided on the side closer to the folding direction of the column, and the axial direction of the second groove is inclined so that after the column is unfolded, the first column tilts away from the folding direction of the column, and the second column tilts towards the folding direction of the column.

[0007] Furthermore, the second end of the limiting block is close to the folding direction of the column, and the end of the first groove close to the second end of the limiting block is provided with a straight end face, and the straight end face is parallel to the axis of the second groove, so that the straight end face of the first groove can abut against the side wall of the first column.

[0008] Furthermore, the inclined surface of the first end of the limiting block cooperates with the inclined surface of the side wall of the pin assembly, so that the angle between the first column and the horizontal direction and the angle between the second column and the first column are complementary, so that the second column remains horizontal after the column is folded.

[0009] Furthermore, the pin assembly includes a bushing disposed at the end of the column, a pin disposed inside the bushing, a first end of the pin being extendable or retractable from the first end of the bushing, and a first elastic element disposed between the second end of the pin and the second end of the bushing, the first elastic element providing elastic force for the pin to extend from the first end of the bushing.

[0010] Furthermore, a zipper assembly is provided at the end of the second column. The zipper assembly includes a zipper disposed inside the column and a handle assembly near the end of the second column. The first end of the zipper is connected to a pin assembly, and the second end of the zipper extends toward the end of the second column and is connected to the handle assembly. Moving the handle assembly can cause the zipper to move along the axial direction of the second column.

[0011] Furthermore, a first rotating shaft is provided inside the end of the second column, and the zipper is connected to the handle assembly around the first rotating shaft. The first rotating shaft can limit the position of the zipper at the end of the second column.

[0012] Furthermore, the handle assembly includes a connecting plate disposed inside the column and a handle extending to the outside of the column. The connecting plate includes a first connecting plate and a second connecting plate connected to each other at a preset second angle. The connection position of the first connecting plate and the second connecting plate can rotate around a second rotation axis. The end of the first connecting plate is connected to a zipper, and the end of the second connecting plate is connected to a handle. Moving the handle can cause the second connecting plate to rotate around the second rotation axis, so that the first connecting plate drives the zipper to move.

[0013] Furthermore, the handle includes an arc segment connecting the second connecting plate and a smooth segment connecting the arc segment. The radius of the arc segment is the same as the length of the second connecting plate. Pushing the smooth segment of the handle upwards allows the arc segment of the handle to move into the column through the through hole on the column, so that the second connecting plate rotates around the second rotation axis.

[0014] Another aspect of this utility model also provides a treadmill, including the foldable uprights described above.

[0015] This utility model embodiment provides a foldable column with at least the following advantages: 1. The column includes a first column and a second column connected to each other at a preset first angle. The end of the limiting block away from the folding direction of the column is at a certain angle to the base, which can maintain a certain distance between the folded column and the base to facilitate the accommodation of other components. 2. The second groove is set on the side closer to the folding direction of the column, and the axial direction of the second groove is inclined so that the first column tilts away from the folding direction after the column is unfolded, which can disperse the force when the column is unfolded; at the same time, the straight end face of the first groove can abut against the side wall of the first column, further providing support for the unfolded column.

[0016] 3. The inclined surface of the first end of the limiting block cooperates with the inclined surface of the side wall of the pin assembly, so that the angle between the first column and the horizontal direction and the first angle can keep the second column horizontal after the column is folded, and make close contact with the folded base, reduce the folding space and improve the aesthetics after folding.

[0017] 4. The column has a hollow structure. The second end of the pull lock is operated by the handle assembly that extends to both the inner and outer sides of the column. The handle assembly uses the lever principle to make the operation of the handle easier. The handle is also small in size, making it easy to hide and improving the overall aesthetics of the handrail.

[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0026] Figure 1 and Figure 2 This illustration shows a schematic diagram of the foldable column 1 applied to a treadmill in an embodiment of the present invention. It can be understood that the foldable column 1 provided in this embodiment can be applied not only to treadmills but also to other fitness equipment with similar column 1 structures or application scenarios. For ease of description, this invention will primarily focus on the column 1 applied to a treadmill for detailed explanation of the foldable column 1 of the present invention.

[0027] In a preferred embodiment of this invention, the treadmill includes a front running board 4 and a rear running board 5, which are foldable together. A column 1 is rotatably connected to the end of the front running board 4 furthest from the rear running board 5. The column 1 can be rotated as follows: Figure 1 The unfolded state shown and as Figure 2 The folding turntables shown transition between each other, and the end of the column 1 away from the front running board 4 is often equipped with a handrail 6 for user convenience.

[0028] Furthermore, in this embodiment of the invention, the support column 1 includes a first support column 11 and a second support column 12 connected to each other at a preset first angle. The end of the first support column 11 is connected to the base, and the length of the first support column 11 is less than that of the second support column 12. The first support column 11 and the second support column 12 form a certain angle, which allows the support column 1 to have a certain bending angle when unfolded, thus distributing the force on the support column 1 more effectively and improving its supporting strength. It also allows the second support column 12 to be spaced apart from the base after the support column 1 is folded. When the rear running board 5 of the treadmill is folded above the front running board 4, the gap between the second support column 12 and the base can accommodate the rear running board 5.

[0029] In this embodiment of the utility model, a connecting side plate 41 is provided on the base, the connecting side plate 41 protrudes from the base, the column 1 is rotatably connected to the connecting side plate 41, and the rotatable connection point between the column 1 and the connecting side plate 41 is spaced apart from the first end of the column 1, so that the first end of the column 1 can rotate between the first limiting point and the second limiting point.

[0030] In a preferred embodiment of this invention, the connecting side plate includes a first connecting side plate and a second connecting side plate arranged opposite to each other, and the column 1 is rotatably connected between the first connecting side plate and the second connecting side plate. This improves the stability of the rotatable connection of the column 1. By rotatably connecting the connecting side plate 41 to the column 1, this invention allows the rotation center of the column 1 to maintain a distance from its first end. During the rotation of the column 1, the first end of the column 1 can rotate between different positions, thereby locking the column 1 in different positions.

[0031] Furthermore, in this embodiment of the present invention, a limiting block 24 is also provided on the base, and a first groove 25 is provided on the limiting block 24. A second groove 26 is provided on the side of the first groove 25 near the folding direction of the column 1, and the second groove 26 forms a first limiting point. The pin assembly can be inserted into the second groove 26 to make the column 1 unfolded. The first end 27 of the limiting block is away from the folding direction of the column, and the end face of the first end 27 of the limiting block is inclined downward. The pin assembly abuts against the end face of the first end 27 of the limiting block to make the column 1 fold and the second column 12 is spaced apart from the base.

[0032] Specifically, in this embodiment of the invention, the limiting block 24 has a C-shaped structure as shown in the attached drawings, with the opening of the C-shaped structure facing upwards to accommodate the column 1. A second groove 26 is provided on the side of the first groove 25 near the folding direction of the column 1 (i.e., near the second end of the limiting block 24), and the pin 21 can be inserted into the second groove 26 to limit the column 1. The second groove 26 is inclined in the axial direction (e.g., Figure 3 As shown, the bottom end is tilted towards the base, so that when the column 1 is unfolded, the first column 11 tilts away from the direction of column folding, and the second column 12 tilts towards the direction of column folding (as shown). Figure 1 (As shown).

[0033] Furthermore, in this embodiment of the present invention, the second end of the limiting block 24 is positioned close to the folding direction of the column, and the end of the first groove 25 near the second end of the limiting block 24 is provided with a straight end face (this cross-section is a side surface of the C-structure of the first groove 25, not the top surface of the first groove 25), and the straight end face is parallel to the axis of the second groove 26, so that the straight end face of the first groove 25 can abut against the side wall of the first column 11, further improving the stability of the column when it is unfolded.

[0034] Furthermore, the inclined surface of the first end 27 of the limiting block cooperates with the inclined surface of the side wall of the pin assembly, so that the angle between the first column 11 and the horizontal direction and the first angle are complementary, so that the second column 12 remains horizontal after the column 1 is folded.

[0035] In a preferred embodiment of this utility model, the second column 12 is kept horizontal and parallel to the base, which can effectively accommodate the folded treadmill running board.

[0036] Furthermore, such as Figures 3-7 As shown, the foldable column 1 provided in this embodiment of the utility model includes a base and a column 1 rotatably connected to the base. When the foldable column 1 is applied to a treadmill, the base can be the running board of the treadmill. The first end of the column 1 is located near the base and is connected to a pin assembly. A zipper assembly is provided on the column 1. The first end of the zipper assembly is connected to the pin assembly, and the second end is located near the second end of the column 1. Pulling the second end of the zipper assembly can drive the pin assembly to retract into the first end of the column 1 along the axial direction of the column 1, so that the column 1 can rotate around the base. The base is provided with a first limiting point and a second limiting point that match the pin assembly. The pin assembly can extend and insert into the first limiting point to make the column 1 unfolded, or insert into the second limiting point to make the column 1 folded.

[0037] In this embodiment of the utility model, the pin assembly cooperates with the first limiting point and the second limiting point to realize the unfolding and folding of the column 1. At the same time, the zipper assembly extends the unlocking operation of the pin assembly to the end of the column 1 away from the base, that is, the end close to the handrail 6. The user only needs to stand on the handle 36 to unlock the column 1, which is simple and convenient to operate.

[0038] Furthermore, such as Figures 3-4 As shown, the pin assembly includes a bushing 22 disposed at the end of the column 1, a pin 21 disposed inside the bushing 22, the first end of the pin 21 can extend or retract from the first end of the bushing 22, and a first elastic member 23 is disposed between the second end of the pin 21 and the second end of the bushing 22, the first elastic member 23 provides elastic force for the pin 21 to extend out of the first end of the bushing 22.

[0039] Understandably, the first end of the bushing 22 is the first end of the column 1. A through hole is provided at the middle position of the second end of the bushing 22 so that the zipper assembly can be connected to the second end of the pin 21 through the through hole. One end of the first elastic member 23 abuts against the second end of the bushing 22, and the other end abuts against the second end of the pin 21. Therefore, under the action of the elastic force of the first elastic member 23, the pin 21 can extend out of the first end of the column 1. When the zipper assembly is pulled, it can resist the elastic force of the first elastic member 23 and retract the pin 21 back to the first end of the column 1.

[0040] Furthermore, in this embodiment of the present invention, the pin 21 includes a first end, a second end, and a middle portion. The first end is the position that protrudes from the first end of the column 1. The diameter of the first end is smaller than the diameter of the middle portion, so that the first end has a nail-like structure, facilitating insertion into the limiting point. The middle portion has a clearance fit with the bushing 22, facilitating the reciprocating movement of the pin 21 within the bushing 22 and preventing it from wobbling. The diameter of the second end is slightly smaller than the diameter of the middle portion, facilitating the first elastic element 23 to be sleeved on the outside of the second end, improving the connection stability of the first spring. In a specific embodiment of the present invention, the first elastic element 23 is not a spring.

[0041] Furthermore, referring to Figures 5 to 7 In this embodiment of the utility model, the zipper assembly includes a zipper 31 disposed inside the column 1 and a handle assembly disposed near the second end of the column 1. The first end of the zipper 31 is connected to the pin assembly, and the second end of the zipper 31 extends toward the second end of the column 1 and is connected to the handle assembly. Turning the handle 36 can drive the zipper 31 to move along the axial direction of the column 1.

[0042] In a specific embodiment of this utility model, the column 1 has a hollow structure, and a zipper 31 is provided along the axial direction of the column 1. The first end of the zipper 31 is connected to a pin assembly. By pulling the zipper 31 at the second end of the column 1, the pin assembly can be moved, thereby unlocking the column 1 from the base. The method of moving the pin assembly by the zipper 31 in this utility model is simple in structure, easy to operate, and reduces the complexity of unlocking the column 1.

[0043] Furthermore, in this embodiment of the present invention, a first rotating shaft 32 is provided inside the column 1 near the second end of the column 1, and the zipper 31 is connected to the handle assembly around the first rotating shaft 32. The first rotating shaft 32 can limit the position of the zipper 31 at the second end of the column 1.

[0044] Specifically, the first rotating shaft 32 can limit the movement point of the second end of the column 1 of the zipper 31. The first rotating shaft 32 can not only keep the zipper 31 and the column 1 approximately parallel, but also, when the handle assembly is turned, make the end of the zipper 31 move closer to or further away from the second rotating shaft, thereby adjusting the length of the zipper 31 pulled to achieve the purpose of unlocking and locking. It can be understood that, in the specific embodiment of this utility model, the column includes a first column 11 and a second column 12, and a rotating shaft is also provided at the inflection point of the first column 11 and the second column 12, so that the zipper 31 always remains parallel to the side wall of the column.

[0045] Furthermore, in this embodiment of the present invention, the handle assembly includes a connecting plate disposed inside the column 1 and a handle 36 extending to the outside of the column 1. The connecting plate includes a first connecting plate 33 and a second connecting plate 35 connected to each other at a preset second angle. The connection position of the first connecting plate 33 and the second connecting plate 35 is rotatable around a second rotation axis 34. The end of the first connecting plate 33 is connected to a zipper 31, and the end of the second connecting plate 35 is connected to the handle 36. Moving the handle 36 causes the second connecting plate 35 to rotate around the second rotation axis, thereby causing the first connecting plate 33 to move the zipper 31. As shown in the attached diagram, when the first connecting plate 33 rotates towards the side wall of the column 1, it can pull the zipper 31 to move away from the rotation axis, thereby unlocking the pin assembly at the first end of the zipper 31. When the first connecting plate 33 rotates towards the first rotation axis 32, it can move the zipper 31 towards the first rotation axis 32, thereby locking the pin assembly at the first end of the zipper 31 at the limit point.

[0046] Furthermore, the handle 36 includes an arc segment 361 connecting the second connecting plate 35 and a smooth segment 362 connecting the arc segment 361. The radius of the arc segment 361 is the same as the length of the second connecting plate 35. Pushing the smooth segment 362 of the handle 36 upwards can cause the arc segment 361 of the handle 36 to move into the column 1 through the through hole, so as to rotate around the second rotation axis 34.

[0047] Specifically, the center of the arc segment 361 of the handle 36 is the second rotation axis 34. At this point, only a small through hole is needed on the column 1 to meet the rotation requirements of the handle 36. When the smooth segment 362 of the handle 36 is pushed upwards, the arc segment 361 extends into the column 1, causing the first connecting plate 33 to rotate towards the side wall of the column 1. This pulls the zipper 31 away from the rotation axis, thus unlocking the pin assembly at the first end of the zipper 31. When the smooth segment 362 of the handle 36 is pressed down, the arc segment 361 rotates out to the outside of the column 1, causing the first connecting plate 33 to rotate towards the first rotation axis 32. This moves the zipper 31 towards the first rotation axis 32, locking the pin assembly at the first end of the zipper 31 at the limit point.

[0048] The zipper assembly provided in this embodiment has a simple structure and ingenious layout. The unlocking operation of the first end of the column 1 can be completed by operating only the small handle 36, which can further improve the user experience.

[0049] This embodiment of the utility model provides a foldable column 1 which has at least the following advantages: 1. The column includes a first column 11 and a second column 12 connected to each other at a preset first angle. The end of the limiting block away from the folding direction of the column is at a certain angle to the base, which can keep a certain distance between the folded column and the base to facilitate the accommodation of other components. 2. The second groove is set on the side closer to the folding direction of the column, and the axial direction of the second groove is inclined so that the first column 11 is inclined away from the folding direction after the column is unfolded, which can disperse the force when the column is unfolded; at the same time, the straight end face of the first groove can abut against the side wall of the first column 11, further providing support for the unfolded column.

[0050] 3. The inclined surface of the first end of the limiting block cooperates with the inclined surface of the side wall of the pin assembly, so that the angle between the first column 11 and the horizontal direction and the first angle can keep the second column 12 horizontal after the column is folded, and make close contact with the folded base, reduce the folding space and improve the aesthetics after folding.

[0051] 4. The column has a hollow structure. The second end of the pull lock is operated by the handle assembly that extends to both the inner and outer sides of the column. The handle assembly uses the lever principle to make the operation of the handle easier. The handle is also small in size, making it easy to hide and improving the overall aesthetics of the handrail.

[0052] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made to the above embodiments by those skilled in the art after reading this specification are all within the scope of protection of the present invention. The various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the embodiments of the present invention will not further describe various possible combinations.

[0053] If the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
