Description

Technical Field

[0001] The invention relates to the field of fitness equipment, in particular to a foldable sports equipment with a self-help force shielding structure. Background Art

[0002] With the continuous improvement of living standards, people pay more and more attention to physical exercise. Therefore, they achieve the purpose of fitness through various types of exercise. Among them, walking and running are the simplest and most effective ways to exercise. Therefore, walking machines and treadmills are becoming more and more popular. In order to facilitate storage, some athletes will choose foldable walking machines or treadmills, and fold them for storage to save space.

[0003] Most of the existing foldable walking machines or treadmills are folded by lifting the entire treadmill upwards. Since the treadmill has a large volume and a heavy mass, some users with less strength have difficulty in folding the treadmill. Therefore, the applicant has developed a walking machine and a treadmill with a foldable treadmill, which greatly reduces the force required for folding. However, after the walking machine and the treadmill with a foldable treadmill are folded and stored, the folded position is exposed to the external environment, and the folding parts are mostly mechanical structures such as hinge mechanisms, which results in the folded position not being beautiful and neat after folding; in addition, after being stored for a long time, dust will fall on the folding position, affecting the normal operation of mechanical structures such as hinge mechanisms, increasing the resistance during folding, affecting the service life of the equipment, and even causing damage to the equipment. Therefore, it is necessary to design a shielding structure to solve the above problems. Summary of the invention

[0004] The present invention provides a foldable sports equipment with a self-help shielding structure, which can shield the exposed part of the sports equipment at the folded position, so as to achieve a relatively neat appearance and prevent dust from falling into it. The specific technical solution is as follows:

[0005] A foldable sports equipment with a self-help shielding structure, comprising a foldable first treadmill and a second treadmill, wherein the first treadmill and the second treadmill are provided with running belts, and a retractable rolling curtain is provided at the connection position between the first treadmill and the second treadmill, wherein one end of the rolling curtain is fixed in the first treadmill, and the other end of the rolling curtain is fixed in the second treadmill; when the first treadmill and the second treadmill are unfolded, the rolling curtain is retracted and located below the running belt; when the first treadmill and the second treadmill are folded, the rolling curtain is extended and wrapped around the outside of the connection position between the first treadmill and the second treadmill to shield the connection position.

[0006] Furthermore, one end of the rolling curtain is fixed in the first treadmill, and the other end of the rolling curtain is wound on the rebounder, which can continuously provide a winding force for the rolling curtain, and the rebounder is fixed in the second treadmill.

[0007] Furthermore, the rebounder includes a fixed rod, which is connected to the rotating sleeve through an elastic component. When the rotating sleeve rotates relative to the fixed rod, the elastic component can provide a restoring force for the rotating sleeve.

[0008] Furthermore, a mounting seat is provided at a lower position of the second treadmill near the end connected to the first treadmill, and an L-shaped slot is provided on the mounting seat. The fixing rod can be placed in the L-shaped slot. The mounting seat is detachably connected to the mounting plate, and the mounting plate can fix the fixing rod in the mounting seat to realize the connection of the rebounder.

[0009] Furthermore, a limiting column is provided between the ends of the mounting seat connected to the second treadmill and the first treadmill. The limiting column is provided on a side of the rolling curtain close to the running belt and contacts the rolling curtain. The limiting column can limit the moving path of the rolling curtain when extending or retracting.

[0010] Furthermore, the limit column can be rotatably fixed on the limit seat, and the limit seat is arranged at the lower position between the end portions where the mounting seat is connected to the second treadmill and the first treadmill. A rotation groove matching the limit column is arranged on the limit seat, and the limit column can be inserted into the rotation groove. The limit seat is detachably connected to the limit plate above, and the limit plate can limit the limit column in the rotation groove.

[0011] Furthermore, an arc-shaped sliding surface is provided on the upper surface of the end portion where the second treadmill is connected to the first treadmill, and a side of the rolling curtain away from the limiting column is in contact with the sliding surface. The sliding surface can support the rolling curtain, and the sliding surface cooperates with the limiting column to form a moving channel for the rolling curtain to extend or retract. The moving channel formed by the sliding surface and the limiting column can prevent the rolling curtain from shaking when it is extended or retracted.

[0012] Furthermore, the height of the limiting column is lower than the height of the sliding surface.

[0013] Furthermore, a limited mounting flange is provided at the end where the first treadmill is connected to the second treadmill, and a mounting platform is provided on the side of the mounting flange away from the second treadmill. A fixing plate is detachably connected to the mounting platform, and the end of the rolling curtain is wound on the fixing plate. A plurality of through holes are provided on the rolling curtain and the fixing plate. The rolling curtain and the fixing plate are fixed to the mounting platform with screws, and the rolling curtain extends out from the gap between the mounting flange and the fixing plate, thereby realizing the installation of the rolling curtain.

[0014] Furthermore, the height of the mounting flange is lower than the height of the upper surface of the end portion where the second treadmill is connected to the first treadmill.

[0015] The structural design of the present invention is ingenious. The exposed part of the folded position of the sports equipment is covered by an automatically retractable roller curtain, thereby preventing dust, water and other debris from falling in. While protecting the safety of the folded position of the sports equipment, the appearance of the folded position of the sports equipment is also made neat and beautiful. The limiting fixation of the rebounder and the moving channel of the roller curtain can effectively prevent the roller curtain from being scratched against structures such as the running belt, ensure the smoothness and stability of the roller curtain when extending or retracting, and greatly improve the user experience.

[0025] In order to better understand the purpose, function and specific design of the present invention, the foldable sports equipment with a self-help force shielding structure of the present invention is further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-7 As shown, the foldable sports equipment with a self-help shielding structure of the present invention comprises a foldable first treadmill 1 and a second treadmill 2, wherein a running belt 3 is arranged on the first treadmill 1 and the second treadmill 2, and a retractable rolling curtain 4 is arranged at the connection position between the first treadmill 1 and the second treadmill 2, wherein one end of the rolling curtain 4 is fixed in the first treadmill 1, and the other end of the rolling curtain 4 is fixed in the second treadmill 2; when the first treadmill 1 and the second treadmill 2 are unfolded, the rolling curtain 4 is retracted and located under the running belt 3; when the first treadmill 1 and the second treadmill 2 are folded, the rolling curtain 4 is extended and wrapped around the outer side of the connection position between the first treadmill 1 and the second treadmill 2 to shield the connection position.

[0027] In one embodiment, the rolling curtain 4 is an elastic belt, which shrinks by its own elasticity, and is disposed below the running belt 3 and spaced apart from the running belt 3 by a distance greater than 5 mm to avoid interference with the running running belt 3. However, since the elastic belt will be difficult to recover if it is in a stretched state for a long time, if the elastic belt is used as the rolling curtain 4, the elastic belt cannot be retracted and interferes with the running belt 3 if the sports equipment is stored for a long time.

[0028] Therefore, in another preferred embodiment, one end of the rolling curtain 4 is fixed in the first treadmill 1, and the other end of the rolling curtain 4 is wound on the rebounder 5, the rebounder 5 can continuously provide winding force for the rolling curtain 4, and the rebounder 5 is fixed in the second treadmill 2; when the first treadmill 1 and the second treadmill 2 are unfolded, the rolling curtain 4 is retracted and the rolling curtain 4 and the rebounder 5 are both located below the running belt 3 and the interval distance is greater than 5 mm; when the first treadmill 1 and the second treadmill 2 are folded, the rolling curtain 4 is released on the rebounder 5, and the rolling curtain 4 extends out and wraps around the outside of the connection position of the first treadmill 1 and the second treadmill 2 to cover the connection position.

[0029] Specifically, if Figure 7As shown, the rebounder 5 includes a fixed rod 51, and the fixed rod 51 is connected to the rotating sleeve 53 through an elastic component 52. When the rotating sleeve 53 rotates relative to the fixed rod 51, the elastic component 52 can provide a restoring force for the rotating sleeve 53. The fixed rod 51 of this embodiment includes a fixed end 511, a limiting end 512 and an insertion end 513. The limiting end 512 is arranged on both sides of the fixed end 511. The limiting end 512 is perpendicular to the fixed end 511. The side of the limiting end 512 away from the fixed end 511 is connected to the insertion end 513. The insertion ends 513 connected to the two limiting ends 512 extend in a direction close to each other and are parallel to the fixed end 511. The insertion end 513 is connected to one end of the elastic component 52, and the other end of the elastic component 52 is connected to the rotating sleeve 53. The two insertion ends 513 are respectively inserted into both sides of the rotating sleeve 53 to achieve the connection of the rotating sleeve 53. The elastic component 52 of this embodiment is a tension spring. It can be understood that when there is only one tension spring, the tension spring can be connected to any insertion end 513, and then connected to the end of the rotating sleeve 53 corresponding to this insertion end 513, so as to complete the assembly of the rebounder 5. When there are two tension springs, each insertion end 513 is connected to a tension spring, and then the two tension springs are respectively connected to the ends of the corresponding rotating sleeves 53.

[0030] Preferably, in order to reduce the difficulty of assembling the rebounder 5, the rebounder 5 of this embodiment includes a tension spring, and the two ends of the rotating sleeve 53 are respectively detachably connected to a plug 54, and the two plugs 54 are provided with insertion holes for connecting the insertion ends 513, one of the plugs 54 is fixedly connected to one end of the tension spring, and the other end of the tension spring is fixedly connected to the corresponding insertion end 513, and then the rotating sleeve 53 is connected to the plug 54 connected to the tension spring, and the other plug 54 is connected to the rotating sleeve 53 and the corresponding insertion end 513 is inserted into the plug 54, and the assembly of the rebounder 5 can be completed.

[0031] like Figure 5-6 As shown, a mounting seat 21 is provided at a lower position of the second treadmill 2 near the end connected to the first treadmill 1, and an L-shaped slot is provided on the mounting seat 21. The connection position of the fixed end 511 and the limiting end 512 of the fixing rod 51 can be placed in the L-shaped slot. The mounting seat 21 and the mounting plate 22 are detachably connected, and the mounting plate 22 can fix the fixing rod 51 in the mounting seat 21 to achieve the connection of the rebounder 5. By providing the L-shaped slot and the mounting plate 22, the fixing rod 51 can be limited in all directions, thereby preventing the rolling curtain 4 from being stuck due to the shaking of the rebounder 5 when extending or retracting, thereby ensuring the smoothness and stability of the rolling curtain 4 when extending or retracting.

[0032] like Figure 3-4As shown, a limiting column 6 is further arranged between the end portions where the mounting seat 21 is connected to the second treadmill 2 and the first treadmill 1. The limiting column 6 is arranged on a side of the rolling curtain 4 close to the running belt 3 and in conflict with the rolling curtain 4. The limiting column 6 can limit the moving path of the rolling curtain 4 when it is extended or retracted, thereby preventing the rolling curtain 4 from rubbing against the running belt 3 and other structures when it is extended or retracted. The limiting column 6 of this embodiment can be rotatably fixed on the limiting seat 23. The limiting seat 23 is arranged at a lower position between the end portions where the mounting seat 21 is connected to the second treadmill 2 and the first treadmill 1. A rotation groove matching the limiting column 6 is arranged on the limiting seat 23. The limiting column 6 can be inserted into the rotation groove. The upper portion of the limiting seat 23 is detachably connected to the limiting plate 24. The limiting plate 24 can limit the limiting column 6 in the rotation groove to prevent the limiting column 6 from falling out of the rotation groove, so as to improve the reliability of the limiting column 6 when working, thereby further ensuring the smoothness and stability of the rolling curtain 4 when it is extended or retracted.

[0033] It is worth noting that the upper surface of the end of the second treadmill 2 connected to the first treadmill 1 in this embodiment is provided with an arc-shaped sliding surface 25, and the side of the rolling curtain 4 away from the limiting column 6 is in conflict with the sliding surface 25. The sliding surface 25 can support the rolling curtain 4, and the sliding surface 25 cooperates with the limiting column 6 to form a moving channel for the rolling curtain 4 to extend or retract. The moving channel formed by the sliding surface 25 and the limiting column 6 can avoid shaking when the rolling curtain 4 is extended or retracted, thereby further ensuring the smoothness and stability of the rolling curtain 4 when it is extended or retracted. It can be understood that the sliding surface 25 can also reduce the friction between the rolling curtain 4 and the end of the second treadmill 2 to avoid damage to the rolling curtain 4. Preferably, the height of the limiting column 6 is lower than the height of the sliding surface 25 to form a moving channel with a negative angle, that is, a moving channel away from the running belt 3, thereby further avoiding the rolling curtain 4 and the running belt 3 and other structures from scratching, and ensuring the smoothness and stability of the rolling curtain 4 when it is extended or retracted. In addition, after the second treadmill 2 is folded with the first treadmill, the movable channel can also ensure that there is no large gap between the roller curtain 4 and the end position of the treadmill after it is extended, thereby ensuring the effectiveness of shielding.

[0034] The end of the first treadmill 1 connected to the second treadmill 2 is provided with a mounting flange 11, and a mounting platform 12 is provided on the side of the mounting flange 11 away from the second treadmill 2. A fixing plate 13 is detachably connected to the mounting platform 12. The end of the rolling curtain 4 is wound on the fixing plate 13. The rolling curtain 4 and the fixing plate 13 are provided with a plurality of through holes. The rolling curtain 4 and the fixing plate 13 are fixed to the mounting platform 12 by screws. The rolling curtain 4 extends out from the gap between the mounting flange 11 and the fixing plate 13, thereby realizing the installation of the rolling curtain 4. The triple fixation is formed by the fixing of the screws, the pressing between the fixing plate 13 and the mounting platform 12, and the clamping between the mounting flange 11 and the fixing plate 13, which effectively improves the reliability of the connection between the rolling curtain 4 and the first treadmill 1. Preferably, the height of the mounting flange 11 is lower than the height of the upper surface of the end connected to the second treadmill 2 and the first treadmill 1, that is, the height of the mounting flange 11 is lower than the height of the sliding surface 25, so that the friction of the mounting flange 11 on the rolling curtain 4 is avoided under the support of the sliding surface 25, thereby improving the service life of the rolling curtain 4.

[0035] The roller blind 4 of the present embodiment can be made of materials such as PEVA, PVC, polyester taffeta, Oxford cloth, etc., among which PEVA material is very popular due to its good environmental performance, weather resistance and air permeability; the material itself has the characteristics of sun protection, rain protection and dust protection, can resist the erosion of the external environment for a long time and is not easy to age, which is very suitable for the use environment of the present invention.

[0036] The structural design of the present invention is ingenious. The exposed part of the folded position of the sports equipment is covered by an automatically retractable roller curtain, thereby preventing dust, water and other debris from falling in. While protecting the safety of the folded position of the sports equipment, the appearance of the folded position of the sports equipment is also made neat and beautiful. The limiting fixation of the rebounder and the moving channel of the roller curtain can effectively prevent the roller curtain from being scratched against structures such as the running belt, ensure the smoothness and stability of the roller curtain when extending or retracting, and greatly improve the user experience.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
