Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical rehabilitation equipment, specifically to an anti-gravity treadmill. Background Technology
[0002] An anti-gravity treadmill includes a treadmill platform, a pair of uprights mounted on the platform, handrails mounted on the uprights, and an airbag mounted on the platform. The handrails are equipped with handrails. The bottom of the airbag is connected to the outer edge of the treadmill, and the top of the airbag has an inlet with a straddle strap. The user enters the inlet, straddles the straddle strap, and stands on the treadmill with their lower body inside the airbag. An air pump inflates the airbag, causing it to expand upwards and exert a lifting force on the user to counteract the user's gravity, allowing the user to move lightly on the treadmill.
[0003] To accommodate users of different heights, the handrail is movably connected to the upright and equipped with a locking pin structure. The upright has a locking hole that engages with the locking pin structure. When adjusting the handrail height, the user raises the swing arm on the handrail, causing it to swing upwards and unlocking the locking pin structure. The locking pin structure disengages from the locking hole on the upright, allowing the handrail to move freely up and down along the upright. When the handrail reaches the appropriate height, the swing arm is released to return to its original position, and the locking pin structure re-inserts into the corresponding locking hole to fix the handrail's height on the upright.
[0004] The handrails are located at the rear of the handrail frame, while the swing frame is positioned in front of them to avoid interfering with users' movement on the treadmill. This means that to adjust the handrail height, users must step out of the airbag and move to the front of the handrail frame, either to adjust it before exercising or to have someone else adjust it for them. This is not only inconvenient, but also makes it difficult for users to simultaneously feel the handrail height and adjust it while on the treadmill. Utility Model Content
[0005] The technical problem solved by this utility model is that the swing frame for adjusting the height of the handrail is set in front of the handrail, making it difficult for users to simultaneously feel the height of the handrail on the running platform and adjust the height of the handrail accordingly.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An anti-gravity running platform mechanism includes a running platform, a pair of columns mounted on the running platform, a handrail frame mounted on the pair of columns, and an airbag mounted on the running platform. The bottom of the airbag is connected to the outer edge of the running platform, and the top of the airbag has an inlet. The handrail frame has a locking pin structure, and the columns have locking holes that cooperate with the locking pin structure. The locking pin structure includes a rotating shaft pivotally connected to the handrail frame, a connecting rod connected to the rotating shaft, and a locking pin hinged to the connecting rod. The locking pin is movably inserted into the side wall of the handrail frame and can protrude outwards from the side wall of the handrail frame to cooperate with the locking holes on the columns. A swing frame is fixedly connected to the rotating shaft. The swing frame has a horizontally lying lifting force rod, and the handrail frame has a vertical electric cylinder. The movable part of the vertical electric cylinder has a lifting block located below the lifting force rod. The handrail of the handrail frame has a button for controlling the vertical electric cylinder.
[0007] According to the above technical solution, there are two ways for users to adjust the height of the handrail.
[0008] In the first method, the swing frame is raised upwards, causing it to swing relative to the handrail frame. This drives a pair of rotating shafts on both sides of the swing frame to rotate, simultaneously unlocking the locking pins on the left and right sides. The user raises or lowers the handrail frame to adjust its height. After adjustment, the user releases the swing frame, which simultaneously drives the pair of rotating shafts to rotate in opposite directions. The locking pins on the left and right sides insert into the lock holes on the left and right pillars, respectively, locking the handrail frame and handrail in place.
[0009] In the second method, the user, positioned on the platform, presses a button on the handrail to activate a vertical electric cylinder. This cylinder raises a lifting block, which in turn lifts a lifting force rod. The lifting force rod then causes the entire swing frame to swing upwards, unlocking the locking pin structure from the lock hole in the column. The user can then raise or lower the handrail frame to adjust its height. Afterward, the user resets the vertical electric cylinder by pressing a button, causing the swing frame to return to its original position. The locking pin of the locking pin structure then inserts into the corresponding lock hole in the column, locking the handrail frame and handrail in place.
[0010] The handrail is equipped with an L-shaped electric cylinder support, and the vertical electric cylinder is mounted on the electric cylinder support.
[0011] The handrail is equipped with an upright plate, and a rotating shaft is pivotally connected to the upright plate. The swing frame is fixedly connected to the end of the rotating shaft. Specifically, the swing frame is fixedly connected to the end of the rotating shaft by fastening bolts.
[0012] A tension spring seat is provided on the upright plate, and a tension spring is provided between the lifting force rod and the tension spring seat. When the swing frame swings upward, the tension spring is stretched, and the handrail frame and the upright are unlocked; when the user releases the swing frame, the tension spring releases its elastic potential energy, the swing frame swings downward to return to its original position, and the relative position of the handrail frame and the upright is locked.
[0013] The swing frame includes a pair of side plates and a connecting rod connecting the pair of side plates. The pair of side plates are fixedly connected to a pair of rotating shafts in a one-to-one manner, and the lifting force rod is located between the pair of side plates. If the height of the handrail is manually adjusted, the user raises the handrail frame by holding the connecting rod.
[0014] The anti-gravity running platform of this utility model is equipped with a vertical electric cylinder, and a button for controlling the vertical electric cylinder is set on the handrail. In this way, the user can control the unlocking and locking of the locking pin structure on the running platform to adjust the height of the handrail. The user can personally feel the height of the handrail so that the handrail reaches a suitable height. Attached Figure Description

[0025] Combination Figure 1 , Figure 3The anti-gravity treadmill mechanism includes a treadmill 10, a pair of uprights 20 mounted on the treadmill, handrails 30 mounted on the pair of uprights, and an airbag mounted on the treadmill. The bottom of the airbag is connected to the outer edge of the treadmill, and the top of the airbag has an inlet. The handrails have a locking pin structure, and the uprights have locking holes 21 that cooperate with the locking pin structure. The locking pin structure includes a rotating shaft 40 pivotally connected to the handrails, a connecting rod 41 connected to the rotating shaft, and a locking pin 42 hinged to the connecting rod. The locking pin is movably inserted into the side wall of the handrails and can protrude outwards from the side wall of the handrails to cooperate with the locking holes on the uprights. A swing frame 50 is fixedly connected to the rotating shaft. The swing frame 50 has a horizontally lying lifting force rod 51, and the handrails have a vertical electric cylinder 31. The moving part of the vertical electric cylinder has a lifting block 32, which is located below the lifting force rod. The handrails 35 of the handrails have buttons for controlling the vertical electric cylinder.
[0026] like Figure 3 The handrail frame 30 is provided with an L-shaped electric cylinder support 33, and the vertical electric cylinder 31 is mounted on the electric cylinder support.
[0027] The handrail 30 is provided with an upright plate 36, the rotating shaft 40 is pivotally connected to the upright plate, and the swing frame 50 is fixedly connected to the end of the rotating shaft.
[0028] A tension spring seat 37 is provided on the upright plate 36, and a tension spring is provided between the lifting force rod 51 and the tension spring seat.
[0029] The swing frame 50 includes a pair of side plates 52 and a connecting rod 53 connecting the pair of side plates. The pair of side plates are fixedly connected to a pair of rotating shafts 40 in a one-to-one manner. The lifting force rod 51 is located between the pair of side plates.
[0030] There are two ways for users to adjust the height of the armrest 35.
[0031] The swing frame 50 is raised upwards, causing it to swing relative to the handrail frame 30. This drives a pair of rotating shafts 40 on both sides of the swing frame to rotate, simultaneously unlocking the locking pin structures on the left and right sides. The user raises or lowers the handrail frame 30 to adjust the height of the handrail 35. After adjustment, the user releases the swing frame, which simultaneously drives the pair of rotating shafts 40 to rotate in opposite directions. The locking pin 42 of the left locking pin structure inserts into the lock hole 21 of the left column 20, and the locking pin of the right locking pin structure inserts into the lock hole of the right column, locking the positions of the handrail frame 30 and the handrail 35.
[0032] Alternatively, the user, positioned on the running platform 10, presses a button on the handrail 35 to activate the vertical electric cylinder 31. This cylinder drives the lifting block 32 to rise, which in turn raises the lifting force rod 51. The lifting force rod then causes the entire swing frame 50 to swing upwards, unlocking the locking pin structure from the locking hole 21 of the column 20. The user can then raise or lower the handrail frame to adjust the height of the handrail 35. Afterwards, the user resets the vertical electric cylinder 31 by pressing a button, causing the swing frame 50 to return to its original position. The locking pin 42 of the locking pin structure then inserts into the corresponding locking hole 21 of the column 20, locking the handrail frame 30 and the handrail 35 in place.
[0033] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
