Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a Pilates bed with height-adjustable legs. Background Technology

[0002] Pilates, a popular fitness method, effectively works the deep small muscle groups of the body through specific training movements, improving posture and strengthening core strength. A Pilates bench is a core support device used in Pilates training; it typically includes a movable slide, spring system, and frame structure, providing support and adjustable resistance for the user.

[0003] In practical use, Pilates beds need to cater to users of varying heights and body types. Furthermore, Pilates exercises are diverse, and some advanced or rehabilitative movements may require the bed to be at a specific height to ensure proper form, safety, and maximize training effectiveness.

[0004] However, most Pilates beds on the market have a fixed leg height. This standardized design results in limited versatility and makes it difficult to meet the individual needs of different users. When the bed height is unsuitable, users may find it difficult to maintain proper posture, which not only affects the quality of training but may also increase the risk of sports injuries. This limits the application scenarios and user experience of Pilates beds.

[0005] Therefore, this utility model proposes a Pilates bed with height-adjustable legs to address the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of fixed leg height, poor versatility, and lack of effective heat dissipation and cooling devices in existing Pilates beds, which affect the comfort of use, this utility model aims to provide a Pilates bed with height-adjustable legs that has been structurally improved and can effectively solve the above problems.

[0007] This utility model provides a Pilates bed with height-adjustable legs, including: a bed frame, an adjustment mechanism disposed under the bed frame, and a blower mechanism fixed to the side wall of the bed frame.

[0008] The adjustment mechanism includes a support plate, a fixed rod, a support leg, a connecting plate, a lead screw, a worm gear, a square block, and a worm. The support plate is fixed to the bed frame, the fixed rod is fixedly connected to the support plate, the connecting plate is fixed to the inner wall of the support leg and slidably sleeved on the fixed rod, the lead screw is rotatably mounted on the support plate and threadedly engaged with the support leg, the worm gear is coaxially fixedly connected to the lead screw, the square block is fixed to the support plate, and the worm gear is rotatably mounted inside the square block and meshes with the worm gear.

[0009] Furthermore, the blower mechanism includes a slide plate, a cross slide plate, a fan, a reset reel, and a pulling assembly; the cross slide plate is slidably connected to the slide plate, the fan is fixed to the cross slide plate, and the reset reel and the pulling assembly are both connected to the cross slide plate.

[0010] Preferably, the square block is fixed to the support plate, and one end of the worm gear extends out of the square block and is connected to an operating component for rotation. This structure design facilitates convenient and labor-saving manual operation of the height adjustment mechanism by the user.

[0011] Preferably, the upper end of the lead screw is rotatably mounted on the support plate via a bearing, and the worm gear is fixed to the rod body of the lead screw located above the support plate. By using the bearing, the frictional resistance of the lead screw during rotation can be significantly reduced, making the height adjustment process smoother and more stable.

[0012] Preferably, the blower mechanism further includes a battery, which is fixed to the cross-shaped sliding plate and electrically connected to the fan; this design allows the blower mechanism to work as an independent power supply module, eliminating the need for complex wiring from the bed or external sources, thereby simplifying the overall structure and improving ease of use.

[0013] Preferably, the pulling assembly includes a servo motor fixed to one end of the slide plate, a rotating column fixed to the output end of the servo motor, and a pull rope; one end of the pull rope is wound around the rotating column, and the other end is fixedly connected to the cross slide plate. The movement of the cross slide plate is driven by the precise control of the servo motor.

[0014] Preferably, the housing of the reset reel is fixed to the end of the slide plate away from the pulling assembly, and its pull end is fixedly connected to the cross slide plate; this arrangement enables the pulling assembly and the reset reel to work together, responsible for pulling and resetting, and jointly realize the reciprocating motion of the cross slide plate.

[0015] As a further preferred embodiment, the connection point between the pull rope and the cross slide plate, and the connection point between the reset tape and the cross slide plate, are located on opposite sides of the cross slide plate along its sliding direction; this symmetrical force distribution ensures that the cross slide plate maintains a stable posture during reciprocating motion, effectively preventing deflection or jamming.

[0016] Preferably, the cross slide plate has a shape adapted to the cross section of the slide plate to ensure its stability and guidance during sliding; at the same time, the fan is fixed to the side of the cross slide plate facing the center of the bed to ensure that the airflow can be accurately directed to the user who is training on the bed.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem of existing Pilates beds having a fixed height and being unable to adapt to users of different heights and diverse training postures by setting up an adjustment mechanism consisting of a worm, a worm wheel, a lead screw, and a support leg. The worm drives the worm wheel, which in turn drives the lead screw to rotate, thereby causing the lead screw to drive the support leg to rise and fall. This achieves the effect of being able to adjust the height of the bed as needed and with little effort. Moreover, the meshing transmission of the worm wheel and worm has self-locking properties, ensuring the stability of the adjusted height and safety of use. 2. This utility model solves the problem that the support leg may rotate synchronously with the screw when the screw rotates and rises, which may lead to adjustment failure or jamming. It effectively prevents the support leg from rotating, ensures that it can only make smooth up and down linear movements, and improves the reliability of adjustment. 3. This utility model, by setting up a blower mechanism, utilizes the servo motor and pull rope in the pull assembly, in conjunction with the reset belt, to drive the fan mounted on the cross slide plate to reciprocate along the slide plate. This solves the problem of users feeling stuffy during training and the limited airflow range of the fixed fan. It provides users with a wide range of dynamic airflow, effectively dissipates heat and cools down, and improves training comfort and safety. Attached Figure Description

The Pilates bed also includes an adjustment mechanism 2 and a blower mechanism 3. The adjustment mechanism 2 is located below the bed frame 1 and is used to adjust the height of the bed frame 1. The blower mechanism 3 is fixed to the side wall of the bed frame 1 and is used to provide mobile airflow during training.

[0023] like Figure 2 and Figure 3 As shown, the adjustment mechanism 2 includes a support plate 208 fixed to the bed frame 1; a fixing rod 206 fixedly connected to the support plate 208; a support leg 207; a connecting plate 205 fixed to the inner wall of the support leg 207 and slidably sleeved on the fixing rod 206, the sliding cooperation between the connecting plate 205 and the fixing rod 206 is used to prevent the support leg 207 from rotating; the adjustment mechanism 2 also includes a lead screw 204 rotatably disposed on the support plate 208 and threadedly engaged with the support leg 207, specifically, the lead screw 204... The upper end of 4 is rotatably mounted on the support plate 208 via a bearing; the adjustment mechanism 2 also includes a worm gear 202 coaxially fixedly connected to the lead screw 204, the worm gear 202 being fixed to the rod body of the lead screw 204 located above the support plate 208; the adjustment mechanism 2 also includes a square block 201 fixed to the support plate 208, and a worm 203 rotatably mounted in the square block 201 and meshing with the worm gear 202, one end of the worm 203 passing through the square block 201 and connected to an operating component for rotation.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, the blower mechanism 3 includes a slide plate 301 fixed to the side wall of the bed 1; a cross slide plate 302 slidably connected to the slide plate 301; a fan 303 fixed to the cross slide plate 302; and a pulling assembly 306 and a return winding 305 for driving the cross slide plate 302 to reciprocate. Specifically, the cross slide plate 302 has a shape that matches the cross section of the slide plate 301, allowing the cross slide plate 302 to slide stably within the slide plate 301; the fan 303 is fixed to the side of the cross slide plate 302 facing the center of the bed 1 to facilitate blowing air onto the user during training; the blower mechanism 3 also includes a battery 304, which is fixed to the cross slide plate 302 and electrically connected to the fan 303 to provide power for the operation of the fan 303.

[0025] In a specific embodiment, the pulling assembly 306 for driving the cross slide plate 302 includes a servo motor 3061 fixed to one end of the slide plate 301; a rotating column 3062 fixed to the output end of the servo motor 3061; and a pull rope 3063, one end of which is wound around the rotating column 3062, and the other end is fixedly connected to the cross slide plate 302. Correspondingly, the housing of the reset tape 305 is fixed to the end of the slide plate 301 away from the pulling assembly 306, and its pull end is fixedly connected to the cross slide plate 302. Furthermore, the connection point between the pull rope 3063 and the cross slide plate 302, and the connection point between the reset tape 305 and the cross slide plate 302, are respectively located on opposite sides of the cross slide plate 302 along its sliding direction, thereby forming a complete reciprocating drive structure.

[0026] Working principle: When the bed 1 needs to be adjusted, the worm 203 in the square block 201 of the adjustment mechanism 2 is rotated in sequence. When the worm 203 rotates, it meshes with the worm wheel 202, which in turn drives the lead screw 204 to rotate synchronously. During the rotation of the lead screw 204, the outer support leg 207 will be adjusted up and down. When the support leg 207 moves, the outer connecting plate 205 will be restricted by the top fixing rod 206 of the support plate 208 to prevent it from rotating, thus realizing the ability to adjust the height of the bed 1 as needed. By activating the servo motor 3061 in the pulling assembly 306, the servo motor 3061 drives the rotating column 3062 at the output end to rotate and drive the pull rope 3063 to wind up. When the pull rope 3063 winds up, it pulls the cross slide plate 302 in the blower assembly 3 to move within the slide plate 301. During the movement of the cross slide plate 302, it drives the fan 303 to move synchronously and repeatedly. Then the battery 304 supplies power to the fan 303 to blow air. The reset tape 305 is connected to the cross slide plate 302 and can pull it back to its original position, thereby covering different parts of the human body during training and avoiding the limitations of fixed blowing.
