[0001] The present application relates to the technical field of treadmills, and in particular to a treadmill with foldable armrests and a method of using the treadmill. Background Art
[0002] A treadmill is a device that allows an object to be placed on the upper side of a running belt (treadmill) to run or walk indoors, and is used for training or rehabilitation, for example.
[0003] In order to reduce the space occupied by the treadmill, the existing treadmills are usually foldable. In order to speed up and simplify the folding process, there is a one-button full-folding system device for treadmills proposed in publication number CN220676636U. When the user needs to fold and place the treadmill after exercise, he presses the left and right handles of the handrail with his left and right hands at the same time to unlock the gears at the upper end of the column frame until the handrail frame can move as a whole. That is, lightly press the handrail frame to fold down, and use the wire rope to pull the gears at the lower end of the column frame. At this time, the handrail frame and the column frame can both fold down, realizing the one-button automatic full-folding function. However, this type of structure requires both hands to move at the same time to complete the folding, which is more troublesome. Therefore, how to solve the above problem?

The coil spring and the deadweight of the column break through the locking of the ball screw and start to rotate. At the same time, the required lengths of the first and second pull ropes become longer during the rotation of the column. Therefore, the first and second pull ropes start to pull the main shaft to rotate and the first limit slider to slide, so that the column, the control panel and the handrail assembly enter the folding state at the same time. 2) Folding state to normal state In the folded state, the user grabs one of the columns and uses a greater force to break through the rotation force of the coil spring and rotate the column until the column is out of the range of the locking device. The locking device loses the restriction of the column, and the first spring drives the abutment plate, which abuts against the column again and limits the driving force of the coil spring, so that the column enters the normal state. At the same time, the required lengths of the first pull rope and the second pull rope become shorter again, so the second spring can drive the first limit slider and the second limit slider, so that the control panel enters the normal state, and the user rotates the armrest assembly again, the ball screw disengages, and the armrest assembly enters the normal state.
[0014] The beneficial effect of the present application is that in the process of converting from the normal state to the folded state, it is only necessary to use the foot or one hand to press the abutment plate to complete the synchronous folding of the column, the control panel and the armrest assembly. At the same time, when it is necessary to convert from the folded state to the normal state, it is only necessary to rotate the column with one hand, and the normal state of the column and the control panel can be locked when it is turned to a predetermined position. After that, it is only necessary to rotate one end of the armrest block to complete the folding of the armrest assembly. It is very simple and quick and can complete a simple unfolding, and it is also very friendly to users who are not convenient to use one hand. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In the embodiments of this application, please refer to Figure 1-13As shown, the present application provides a treadmill with foldable armrests and a method for using the same, which mainly include: a treadmill 1, wherein a fixed axis 11 is arranged on the treadmill 1, a treadmill cover 12 is arranged above the treadmill 1, and a locking device 13 is arranged on one side of the treadmill cover 12; a column 2, which is rotatably arranged at both ends of the fixed axis 11, and a connecting plate 21 is installed on the top of one side of the column 2, and an arc groove 211 is opened on the connecting plate 21, and a first limiting slider 212 and a second limiting slider 213 are slidably arranged in the arc groove 211, and a reset portion 214 is also arranged on one side of the arc groove 211, and the reset portion 214 can drive the second limiting slider 213 to always move in the direction of the first limiting slider 212; an armrest assembly 3, including an armrest block 31 and a main axis 32, and between the two armrest blocks 31 A main shaft 32 is fixedly arranged, and a first clamp 33 is arranged on the connecting plate 21 for connecting the main shaft 32; a control panel 4 is rotatably arranged on the main shaft 32, a panel bracket 41 is arranged inside the control panel 4, a second clamp 42 is arranged on the panel bracket 41 for rotatably connecting with the main shaft 32, and a limiting rod 43 is also arranged on the panel bracket 41, and the limiting rod 43 can be driven by the first limiting slider 212 and the second limiting slider 213; a first pull rope 5 and a second pull rope 6 are arranged in the column 2, one end of the first pull rope 5 is connected to the fixed shaft 11, and the other end is connected to the main shaft 32, one end of the second pull rope 6 is connected to the fixed shaft 11, and the other end is connected to the first limiting slider 212; the column 2 can make the treadmill enter the normal state and the folding state by rotating.
[0032] Specifically, when the column 2 rotates to the folded state, the fixed axis 11 does not move, and the column 2 rotates with the fixed axis 11 as the axis.

[0033] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.
[0034] Reference Figure 5As shown, the locking device 13 includes a first spring 131 and a locking rod 132. A spring groove 133 is provided on one side of the treadmill cover 12. The first spring 131 is arranged in the spring groove 133. One end of the locking rod 132 abuts against the first spring 131, and the other end passes through the treadmill cover 12 and is installed with an abutment plate 134. The abutment plate 134 can limit the rotation of the column 2 under normal conditions. The first spring 131 can drive the locking rod 132 to always move outward, so that the abutment plate 134 can be automatically locked when the column 2 rotates to a predetermined position.
[0035] Reference Fig.13 As shown, in order to enable the armrest assembly 3 to be fixed in different states, a fixing block 215 is also installed on one side of the connecting plate 21, and a ball screw 216 is provided on the fixing block 215. Two limiting holes 34 are opened on the main shaft 32. The ball screw 216 passes through the first clamp 33 and can form a limiting fit with the limiting hole 34 in the folded state and the normal state respectively.
[0036] Reference Figure 8-9 or Figure 11-12 A plurality of pulleys 218 are installed on one side of the column 2 close to the connecting plate 21. The pulleys 218 can cooperate with the first pull rope 5 and the second pull rope 6. The pulleys 218 are used to assist in guiding the first pull rope 5 and the second pull rope 6 when they move.
[0037] Reference Figure 6 As shown, in order to enable the column 2 to rotate automatically when it loses the support of the locking device 13, connecting columns 111 are installed at both ends of the fixed axis 11, and the column 2 is provided with a connecting portion 22 on the side connected to the fixed axis 11, and a coil spring 221 is provided in the connecting portion 22, the axis of the coil spring 221 is fixedly connected to the connecting column 111, and the outer periphery of the coil spring 221 is fixedly connected to the inside of the connecting portion 22, and the coil spring 221 is used to apply a force to rotate the column 2 always in the direction of the folded state.
[0038] Reference Figure 4 As shown, in order to enable the control panel 4 to automatically unfold when converting from the folded state to the normal state, the reset portion 214 includes an outer arc groove 2141 and a second spring 2142, one end of the second spring 2142 is fixedly connected to the outer arc groove 2141, and the other end abuts against the second limiting slider 213.
[0039] Reference Figure 8 or Fig.11 A plurality of limiting columns 217 are provided on one side of the connecting plate 21 , and the second pull rope 6 changes the force direction through the limiting columns 217 .
[0040] Preferably, a damping plate is provided between the first clamp 33 and the main shaft 32, and a bearing is provided between the second clamp 42 and the main shaft 32. The damping plate can slow down the rotation of the column 2 driven by the coil spring 221, and the bearing is used to assist the control panel 4 to rotate to prevent jamming during resetting.
[0041] The method for using the treadmill with foldable handrails described above includes the following use stages: 1) Normal state transition to folded state Under normal conditions, the user presses the abutment plate 134 with his foot or hand until the abutment plate 134 enters between the column 2 and the treadmill cover 12, and the column 2 loses the abutment of the abutment plate 134, and the weight of the coil spring 221 and the column 2 break through the locking of the ball screw 216 and starts to rotate. At the same time, during the rotation of the column 2, the required lengths of the first pull rope 5 and the second pull rope 6 become longer, so the first pull rope 5 and the second pull rope 6 start to pull the main shaft 32 to rotate and the first limit slider 212 to slide, so that the column 2, the control panel 4 and the handrail assembly 3 enter the folding state at the same time; 2) Folding state to normal state In the folded state, the user grabs one of the columns 2 and uses a greater force to break through the rotation force of the coil spring 221 and rotate the column 2 until the column 2 is out of the range of the locking device 13. The locking device 13 loses the restriction of the column 2, and the first spring 131 drives the abutment plate 134. The abutment plate 134 abuts against the column 2 again and limits the driving force of the coil spring 221, so that the column 2 enters the normal state. At the same time, the required length of the first pull rope 5 and the second pull rope 6 becomes shorter again, so the second spring 2142 can drive the first limit slider 212 and the second limit slider 213, so that the control panel 4 enters the normal state, and the user rotates the armrest assembly 3 again, and the ball screw 216 disengages, so that the armrest assembly 3 enters the normal state.
