Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of treadmills, in particular to a folding treadmill. BACKGROUND

[0002] Treadmills are commonly used in families and gyms, and are the simplest of all home fitness equipment, making them the best choice for home fitness.

[0003] Existing treadmills are generally divided into mechanical treadmills and electric treadmills. Older people can choose mechanical treadmills, which are a kind of active running mode, and the speed of running is controlled by oneself. Users can walk, jog or run according to their own conditions. Young people can choose electric treadmills, which are a kind of passive running mode. The running speed is set according to the physical ability, and the forced trainer runs at this speed.

[0004] However, existing treadmills are usually sold as finished products. Since the finished product occupies a large space and the space is difficult to utilize when packaging, it is not easy to transport during the selling process and moving process.

[0005] Therefore, there is an urgent need to design a treadmill that is easy to store and package. SUMMARY

[0006] The present application provides a folding treadmill, which can conveniently store, package and transport the treadmill, and meet different needs of users.

[0007] The present application provides a folding treadmill, which adopts the following technical solutions: A folding treadmill includes a running platform, a handrail and a support frame. The handrail is rotationally connected to the running platform, and when it rotates to the limit position towards the running platform, it surrounds the running platform, and when it rotates to the limit position away from the running platform, it is above the running platform. The support frame is rotationally connected to the running platform, and its rotation axis is parallel to the rotation axis of the handrail. When the support frame rotates to the limit position away from the running platform, it supports the running platform to make it in an inclined state, and when the support frame rotates to the limit position towards the running platform, it contacts the bottom of the running platform.

[0008] By adopting the above technical solutions, the handrail and the support frame can be conveniently folded, stored, packaged and transported. When the handrail is rotated and removed, it can meet the needs of users to exercise on a flat running platform. When the handrail and the support frame are simultaneously rotated and removed, it can meet the needs of users to exercise on a running platform with a slope.

[0009] Optionally, a plurality of damping pads are further included, and the plurality of damping pads are respectively arranged on the bottom of the treadmill and the support frame; when the support frame rotates to the limit position towards the direction close to the treadmill, the treadmill and the support frame are both supported by the damping pads to contact the ground; The support frame comprises a frame body and a plurality of rollers; The frame body is rotationally connected with the treadmill, and the rollers are rotationally installed at one end of the frame body away from the treadmill.

[0010] By adopting the above technical scheme, the damping pads can effectively reduce the damage to the treadmill during exercise, and can effectively reduce the noise generated during use of the treadmill; the rollers can facilitate the user to move the treadmill to change the position of the treadmill during use of the treadmill.

[0011] Optionally, the support frame further comprises two stop blocks for inhibiting rotation of the rollers; The frame body comprises two leg rods, and the support frame comprises two rollers, and the two rollers are respectively located at one end of the two leg rods away from the treadmill; The two stop blocks correspond to the two leg rods one by one, the stop blocks are slidingly arranged on the leg rods along the length direction of the leg rods, and one side of the stop block close to the roller is provided with a clamping groove for clamping the roller; When the stop block slides to the limit position towards the direction close to the roller, the roller is clamped in the clamping groove, and the groove wall of the clamping groove is in contact with the roller.

[0012] By adopting the above technical scheme, when the support frame rotates to the limit position, the stop block can effectively prevent the roller from rotating, thereby effectively improving the position stability of the treadmill during use, and further improving the safety of the user using the treadmill.

[0013] Optionally, when the frame body rotates to the limit position away from the treadmill and the stop block stops the roller, the stop block is in contact with the ground.

[0014] By adopting the above technical scheme, after the stop block is in contact with the ground, the resistance between the treadmill and the ground can be increased, thereby further improving the position stability of the treadmill during use, and further reducing the influence of vibration during use of the treadmill.

[0015] Optionally, the stop block is elastic, and when the stop block slides to the limit position towards the direction close to the roller, the stop block is in interference fit with the leg rod.

[0016] By adopting the above technical solution, the positional stability of the stop block when stopping the roller can be improved, and the probability of the stop block slipping and losing its stop on the roller due to vibration during the use of the treadmill can be reduced.

[0017] Optionally, the inner side of the stop block has a guide strip, and the leg is provided with a guide groove for the guide strip to engage. The guide groove has a first positioning section at one end near the running platform. When the guide bar slides to the first positioning section, the stop block is positioned, and when the frame rotates to its limit position in the direction close to the running platform, the stop block contacts the ground.

[0018] By adopting the above technical solution, the stop block can be easily positioned when it slides away from the roller. At this time, the stop block can play a buffering role during the rotation and retraction of the support frame, reducing the probability of damage to the support frame and the running platform caused by the impact of the instantaneous fall of the running platform.

[0019] Optionally, the guide groove has a second positioning section at one end near the running platform, the second positioning section being located on one side of the first positioning section; when the guide bar is located in the first positioning section and the frame rotates to its limit position in the direction of approaching the running platform, the stop block deforms so that the guide bar is located in the second positioning section, and the stop block contacts the ground.

[0020] By adopting the above technical solution, when the stop block plays a buffering role during the rotation and retraction of the support frame, it can further buffer the movement by moving from the first positioning section to the second positioning section. At the same time, it can facilitate the support frame to leave the ground after rotation and retraction, and further improve the vibration reduction effect during the use of the treadmill.

[0021] Optionally, a switching component is rotatably provided on the leg bar, and the switching component has a switching groove adapted to the guide bar; The switching element is located at the junction of the first positioning segment and the second positioning segment near the end of the roller, and when the switching element is rotated to the limit position, the switching groove is connected to the first positioning segment or the second positioning segment.

[0022] By adopting the above technical solution, users can easily control the stop block to slide to the first positioning segment or the second positioning segment according to their needs, and users can easily control the stop block to slide towards the roller according to their needs.

[0023] Optionally, when the frame rotates to its limit position in the direction closer to the running platform, the switching component keeps the switching groove connected to the second positioning section under its own gravity; when the frame rotates to its limit position in the direction away from the running platform, the switching component keeps the switching groove connected to the first positioning section under its own gravity.

[0024] By adopting the above technical solution, the switching component can maintain a suitable position under different usage conditions of the support frame, which makes it convenient for the user to control the stop block to slide towards the roller before the support frame needs to be rotated and removed, and also makes it convenient for the user to control the stop block to slide to the first positioning section before the support frame needs to be rotated and retracted.

[0025] Optionally, the leg bar is further provided with a locking element and an elastic element at one end near the running platform, and the bottom of the running platform has two locking slots for the locking element to be inserted and locked. The locking member is movably connected to the leg rod, and its direction of movement is perpendicular to the rotation axis of the frame; the two ends of the elastic member are respectively connected to the locking member and the leg rod, and it has a tendency to drive the locking member to move closer to the leg rod. When the frame rotates to its limit position in the direction of approaching the running platform, the locking member aligns with the locking groove along its direction of movement. During the process of the guide bar moving from the first positioning section to the second positioning section, the stop block contacts the locking member and drives the locking member to engage and lock with the locking groove.

[0026] By adopting the above technical solution, the cooperation between the stop block sliding and the locking component allows users to easily rotate and lock the position of the support frame according to their needs, improving the positional stability of the support frame after it is rotated to its limit position towards the running platform, and reducing the probability of increased vibration during treadmill use due to the rotational freedom of the support frame.

[0027] In summary, this application includes at least one of the following beneficial effects: 1. It facilitates the storage, packing, and transportation of treadmills, while also meeting the diverse needs of users. 2. It can improve the positional stability of the treadmill during use, while reducing the impact of vibration caused by different modes of use; 3. It can reduce the probability of treadmill damage caused by impact when the support frame is removed or not, and improve the safety of using the treadmill when the support frame is removed or not.

[0030] The following is in conjunction with the appendix Figures 1-10 This application will be described in further detail.

[0031] Example 1: This application discloses a foldable treadmill, which makes it easy to store, pack, and transport the treadmill with less space after folding. At the same time, it allows users to adjust it according to different needs and provides different exercise functions.

[0032] Reference Figure 1 and Figure 2 The folding treadmill includes a running platform 1 that provides exercise functions for the user, handrails 2 that provide support for the user's exercise, and a support frame 3 for adjusting the placement of the running platform 1.

[0033] The treadmill 1 has a rectangular parallelepiped structure, allowing the user to run along its length from the top. In this embodiment, since the treadmill 1 is prior art, it will not be described in detail here, and the accompanying drawings only provide a brief representation.

[0034] The handrail 2 has an arch-shaped structure, with its two extended ends at the bottom rotatably connected to both sides of the running platform 1 in the width direction. Its rotation axis is parallel to its own width direction and also parallel to the width direction of the running platform 1. The handrail 2 is restricted in its rotation relative to the running platform 1. When the handrail 2 rotates to its limit position in the direction closer to the running platform 1, the length direction of the handrail 2 is parallel to the length direction of the running platform 1. The part of the handrail 2 that surrounds the running platform 1 and is supported by the user is located on the side of the running platform 1 away from the rotation connection position of the handrail 2 in the length direction. When the handrail 2 rotates to its limit position in the direction away from the running platform 1, the length direction of the handrail 2 will extend upwards along the direction of the user's movement on the running platform 1, making it convenient for the user to run on the running platform 1 while holding onto the handrail 2. In this embodiment, it is preferred that the handrail 2 can maintain its current position when rotated to its limit relative to the running platform 1 (achieved by a lock); and it is preferred that both the handrail 2 and the running platform 1 are equipped with a control panel for controlling the operation of the running platform 1, so that the user can control the running platform 1 in different usage states of the treadmill; since the lock and control panel with the above functions are existing technologies in the art, they will not be described in detail here, and the lock is omitted in the drawings and the control panel is only briefly shown.

[0035] The support frame 3 is installed at the bottom of the running platform 1, located at one end of the running platform 1 along its length. When the handrail 2 is rotated to its limit position in the direction closer to the running platform 1, the support frame 3 is located at the end of the running platform 1 away from the handrail 2 for the user to hold onto.

[0036] The support frame 3 includes a frame 31 for supporting the frame and two rollers 32 for facilitating the movement of the frame 31.

[0037] The frame 31 has a rectangular frame structure, with one end in the width direction rotatably connected to one end in the length direction of the running platform 1. Its rotation axis is parallel to its own length direction and also parallel to the width direction of the running platform 1. The frame 31 is restricted during rotation relative to the running platform 1. When the frame 31 rotates to its limit position towards the running platform 1, it contacts the bottom of the running platform 1, and at this time, the width direction of the frame 31 is parallel to the length direction of the running platform 1. When the frame 31 rotates to its limit position away from the running platform 1, its width direction extends downwards along the direction of the user's movement on the running platform 1, and at this time, the running platform 1 is placed on the ground with its movement direction tilted upwards. In this embodiment, it is preferable that the frame 31 can maintain its current position when rotating to its limit position relative to the running platform 1 (achieved through a lock). Since locks with the above functions are existing technology in the field, they will not be described in detail here, and the locks are omitted from the accompanying drawings.

[0038] Reference Figure 2 and Figure 3The frame 31 includes two legs 311 and a crossbar 312, and the two legs 311 are fixedly connected by the crossbar 312 to ensure the structural strength of the frame 31. In this embodiment, preferably, the length direction of the crossbar 312 is perpendicular to the length direction of the legs 311, and the connection position of the crossbar 312 and the legs 311 is closer to the end of the legs 311 away from the running platform 1.

[0039] Two rollers 32 correspond one-to-one with two leg posts 311. The rollers 32 are rotatably mounted on the end of the corresponding leg post 311 away from the running platform 1, and their rotation axis is parallel to the length direction of the frame 31. As the support frame 3 rotates away from the running platform 1, it contacts the ground through the two rollers 32. In this embodiment, since the rollers 32 are common prior art, they will not be described in detail here, and they are only briefly shown in the accompanying drawings.

[0040] Furthermore, to facilitate the placement of the running platform 1 on the ground, and to reduce the probability of the treadmill being damaged by bumps during use, as well as to reduce the impact of vibration during the use of the treadmill, the preferred folding treadmill also includes multiple elastic shock-absorbing pads 4.

[0041] In this treadmill, shock-absorbing pads 4 are fixedly installed at two corners of the bottom of the running platform 1, away from the support frame 3. These pads allow the running platform 1 to contact the ground. Regardless of the position of the frame 31 relative to the running platform 1, the running platform 1 will always contact the ground through the two shock-absorbing pads 4. Multiple shock-absorbing pads 4 are also fixedly installed on the frame 31 of the support frame 3. When the frame 31 rotates to its limit position towards the running platform 1, the side of the support frame 3 closest to the ground will contact the ground through these multiple shock-absorbing pads 4. In this embodiment, the shock-absorbing pads 4 are preferably made of rubber.

[0042] The implementation principle of a folding treadmill according to an embodiment of this application is as follows: When the treadmill is in the state where the handrail 2 is rotated to the extreme position towards the running platform 1 and the frame 31 is rotated to the extreme position towards the running platform 1, the treadmill has a rectangular structure, which occupies the least space and is convenient for storage, packing and moving; at this time, the treadmill can also meet the user's need to exercise on the stable running platform 1 without using the handrail 2. When the treadmill is in the state where the handrail 2 is rotated to its limit towards the running platform 1 and the frame 31 is rotated to its limit away from the running platform 1, the treadmill can be easily moved to a different position on the ground. At this time, the treadmill can also meet the user's need to exercise on the inclined running platform 1 without using the handrail 2. When the treadmill is in the state where the handrail 2 is rotated to the extreme position away from the running platform 1 and the frame 31 is rotated to the extreme position closer to the running platform 1, the treadmill can meet the user's needs to exercise on the stable running platform 1 when the handrail 2 is needed. When the treadmill is in a state where the handrail 2 is rotated to its limit away from the running platform 1 and the frame 31 is rotated to its limit away from the running platform 1, the treadmill can meet the user's needs to exercise on the inclined running platform 1 when the handrail 2 is needed.

[0043] Example 2: Reference Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that the support frame 3 has been removed from the design of installing the vibration damping pad 4 on the frame 31, and the support frame 3 also includes two stop blocks 33.

[0044] Reference Figure 5 and Figure 6 Two stop blocks 33 correspond one-to-one with two leg rods 311. The stop blocks 33 are slidably sleeved on the corresponding leg rods 311, and their sliding direction is parallel to the length direction of the leg rods 311. In this embodiment, the stop blocks 33 are preferably elastic, and preferably made of rubber.

[0045] Reference Figure 7 and Figure 8 The stop block 33 has a slot 331 on the side near the roller 32 for the roller 32 to be inserted.

[0046] Reference Figure 9 and Figure 10 When the stop block 33 slides to its limit position towards the roller 32, the stop block 33 will be interference-fitted with the corresponding leg bar 311 to give it a certain positional stability. At this time, the corresponding roller 32 will contact and abut against the groove wall of the slot 331, thereby limiting the rotation of the roller 32. When the frame 31 rotates to its limit position away from the running platform 1 and the stop block 33 slides to its limit position towards the roller 32, the roller 32 will be inserted into the inside of the slot 331, and the bottom of the stop block 33 will contact and abut against the ground, increasing the friction between the treadmill and the ground. At the same time, the stop block 33 can also play a shock absorption role.

[0047] Reference Figure 6 and Figure 8The stop block 33 has a cavity inside that slides with the leg rod 311. Guide strips 332 extend along the sliding direction of the stop block 33 on its inner side. A guide groove 3111 that matches the guide strip 332 is provided on the side of the leg rod 311 away from the other leg rod 311. During the sliding process of the stop block 33 relative to the leg rod 311, its guide strip 332 remains engaged with the guide groove 3111.

[0048] A switching element 34 is rotatably mounted on the side of the leg 311 away from the other leg 311, near the center of its own length direction. The switching element 34 is a disc structure, and its rotation axis coincides with its own axis and is parallel to the rotation axis of the frame 31. The switching element 34 breaks the guide groove 3111 and divides the guide groove 3111 into two parts. The part of the guide groove 3111 near the roller 32 of the switching element 34 is a straight line trajectory parallel to the length direction of the leg 311. The part of the guide groove 3111 away from the roller 32 of the switching element 34 has a first positioning segment 3112 and a second positioning segment 3113, and there is a gap between the first positioning segment 3112 and the second positioning segment 3113.

[0049] Reference Figure 5 and Figure 6 The surface of the switching member 34 is provided with a switching groove 341 for the portion of the guide groove 3111 near the roller 32 to communicate with the first positioning section 3112 or the second positioning section 3113. When the switching member 34 rotates relative to the leg 311 to a certain extreme position, the portion of the guide groove 3111 near the roller 32 can communicate with the first positioning section 3112 through the switching groove 341. At this time, controlling the stop block 33 to move away from the roller 32 can make the guide strip 332 of the stop block 33 engage with the first positioning section 3112. When the switching member 34 rotates relative to the leg 311 to another extreme position, the portion of the guide groove 3111 near the roller 32 can communicate with the second positioning section 3113 through the switching groove 341. At this time, controlling the stop block 33 to move away from the roller 32 can make the guide strip 332 of the stop block 33 engage with the second positioning section 3113. In this embodiment, the extension trajectory of the guide groove 3111 located on the part of the switching member 34 near the roller 32 is preferably on the same straight line as the extension trajectory of the first positioning segment 3112, and the second positioning segment 3113 is located on the side of the first positioning segment 3112 near the running platform 1 along the thickness direction of the frame 31; and preferably the guide strip 332 is interference-fitted with both the first positioning segment 3112 and the second positioning segment 3113, so that the stop block 33 can maintain its current position when it slides to the limit position in the direction away from the roller 32.

[0050] Reference Figure 4 and Figure 6When the frame 31 rotates to its limit position in the direction of approaching the running platform 1, if the guide strip 332 of the stop block 33 engages with the second positioning section 3113, the stop block 33 will just contact the ground; if the guide strip 332 of the stop block 33 engages with the guide groove 3111 located on the part of the switching member 34 near the roller 32 or the first positioning section 3112, the stop block 33 will contact the ground and will be subject to the force of the ground, tending to move away from the ground, so that the stop block 33 with the guide strip 332 engaging with the first positioning section 3112 can move along the thickness direction of the frame 31 after being subjected to force, until the guide strip 332 of the stop block 33 engages with the second positioning section 3113.

[0051] Reference Figure 7 and Figure 9 The support frame 3 also includes two locking elements 35 and two elastic elements 36 that correspond one-to-one with the two legs 311.

[0052] The locking member 35 is movably installed at one end of the leg 311 near the running platform 1. Its direction of movement is parallel to the thickness direction of the frame 31, and part of it is located on the side of the leg 311 near the running platform 1 along the thickness direction of the frame 31. A locking groove 11 adapted to the locking member 35 is provided at the bottom of the running platform 1 near the frame 31. When the frame 31 rotates to its limit position in the direction of approaching the running platform 1, the locking member 35 aligns with the adjacent locking groove 11 along its own direction of movement. At this time, when the locking member 35 moves to its limit position in the direction of approaching the running platform 1, the locking member 35 is fully engaged and locked with the locking groove 11. When the locking member 35 moves to its limit position in the direction of away from the running platform 1, the locking member 35 completely leaves the locking groove 11.

[0053] The two ends of the elastic element 36 are fixedly connected to the locking element 35 and the leg bar 311, respectively, and it has a tendency to drive the locking element 35 to move to its limit position in the direction closer to the leg bar 311. In this embodiment, the elastic element 36 is preferably a compression spring.

[0054] When the stop block 33 slides away from the roller 32 to its limit position and the guide bar 332 engages with the first positioning section 3112, the stop block 33 is located on one side of the locking member 35 and a distance is maintained between them. When the stop block 33 slides away from the roller 32 to its limit position and the guide bar 332 engages with the second positioning section 3113, the stop block 33 will contact the locking member 35 and drive the locking member 35 to overcome the force of the elastic member 36 and move away from the leg bar 311 to its limit position.

[0055] Reference Figure 4 and Figure 6Furthermore, the center of gravity of the switching component 34 is preferably set to be eccentric, such that when the frame 31 rotates to the limit position in the direction of approaching the running platform 1, the switching groove 341 is connected to the second positioning section 3113; and when the frame 31 rotates to the limit position in the direction of away from the running platform 1, the switching groove 341 is connected to the first positioning section 3112.

[0056] Reference Figure 7 and Figure 10 At this time, when the frame 31 rotates to its limit position in the direction closer to the running platform 1 and the stop block 33 slides to its limit position in the direction away from the roller 32 and the guide strip 332 engages with the second positioning section 3113, the stop block 33 will keep the locking member 35 locked in the locking groove 11, restricting the frame 31 from rotating relative to the running platform 1; after controlling the stop block 33 to slide in the direction closer to the roller 32 until it separates from the locking member 35, the locking member 35 will move under the action of the elastic member 36 to restore the frame 31 to the freedom of rotation relative to the running platform 1.

[0057] Reference Figure 6 and Figure 9 When the frame 31 rotates to its limit position away from the running platform 1 and the stop block 33 slides to its limit position away from the roller 32, and the guide strip 332 engages with the first positioning section 3112, during the process of controlling the frame 31 to rotate towards the running platform 1, when the frame 31 is about to contact and abut against the running platform 1, the stop block 33 will contact the ground and move after being subjected to force, causing the guide strip 332 to engage with the second positioning section 3113. At this time, the locking member 35 is in a state of being ready to be inserted into the locking groove 11. When the locking member 35 is aligned with the locking groove 11 along its own direction of movement, it can be inserted into the locking groove 11. During this process, the stop block 33 can effectively play a role in buffering and damping vibration.

[0058] The implementation principle of a folding treadmill according to an embodiment of this application is as follows: When the treadmill is in the state where the frame 31 is rotated to the limit position away from the running platform 1, after the stop block 33 is slid to the limit position in the direction close to the roller 32, the stop block 33 will stop the roller 32 and contact the ground, improving the stability of the treadmill during use. Subsequently, when the treadmill needs to be rotated to its limit position with the frame 31 moving towards the running platform 1, the stop block 33 is first controlled to slide away from the roller 32 to its limit position, so that the guide bar 332 engages with the first positioning section 3112. Then, the frame 31 is controlled to rotate towards the running platform 1. During this process, the gravity of the running platform 1 will accelerate the rotation speed of the frame 31. When the frame 31 is about to contact the running platform 1, the stop block 33 will buffer it and then move to engage the guide bar 332 with the second positioning section 3113. After that, the locking member 35 will be driven to engage with the locking groove 11 to lock, thereby improving the positional stability of the frame 31 relative to the running platform 1 in this state.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
