Description

Technical Field

[0001] This invention relates to the field of rehabilitation therapy equipment technology, and in particular to an exercise device for bedridden patients. Background Technology

[0002] Bedridden patients are often bedridden due to various reasons, such as limb paralysis caused by stroke, limb joint stiffness caused by postoperative sequelae, and joint dysfunction caused by hand injuries. For some bedridden patients, especially those with more severe conditions, the lack of independent exercise ability necessitates assistance with limb movement to prevent diseases such as lung infections, muscle atrophy, and thrombosis. Therefore, bedridden patients require rehabilitation training using limb exercise tools.

[0003] A search revealed that most existing exercise devices are simple tapping and massage devices. To create a noticeable bumpy and squeezing sensation on the back, an upward-protruding mechanism is necessary. However, after the massage, these uneven surfaces remain stationary under the back, causing noticeable pressure marks on the user's back over time and leading to discomfort. Therefore, we propose an exercise device with switchable modes to ensure that there is no noticeable bumpy or squeezing sensation on the back when not in use, thereby enhancing patient comfort. Summary of the Invention

[0004] To address the technical problem that existing massage beds have a noticeable uneven surface when not in use, causing discomfort to the person sleeping on them, this invention adopts the following technical solution: An exercise device for bedridden patients includes a main frame with a rectangular frame structure adapted to the size of the bed surface.

[0007] Preferably, the rolling and pressing mechanism includes cantilever rods fixed to the inner wall of the conversion frame, extending horizontally towards the center from both sides near the rectangular hole. Two upward-opening, parallel grooved slide rails are fixed to opposite ends of the four cantilever rods, and convex sliders are slidably connected to each of the two grooved slide rails.

A bumping bracket extending towards the center of the rectangular hole is slidably connected to the top opening of the slide barrel, and two compression springs are fixed between the bottom end of the bumping bracket and the bottom of the barrel. Hinges are provided on both sides of the bumping bracket near the top and on the top of the Y-shaped bracket on the corresponding side.

[0009] Preferably, the inner wall of the conversion frame is provided with a reciprocating pushing mechanism below the slide barrel, and the reciprocating pushing mechanism includes sliding bearings embedded in the openings of two transmission pipes, and the same reciprocating push rod is slidably connected between the two sliding bearings; a rack is welded to the outer wall of the reciprocating push rod, and an L-shaped fixing rod is fixed between the outer wall of the reciprocating push rod and the slide barrel; the pushing and pulling force is transmitted through the L-shaped fixing rod to drive the operation of the rolling and pressing mechanism; an H-shaped support frame extending towards the middle of the reciprocating push rod is fixed to the inner wall of the conversion frame, and a horizontal shaft perpendicular to the rack is provided at the top of the H-shaped support frame, and a coaxial swing gear meshing with the driven swing rod and the rack is fixed on the horizontal shaft.

[0010] Preferably, a separate drive module is provided on the upper surface of the bearing seat away from the L-shaped fixed rod; and multiple centrally symmetrical shaft fixing frames are fixed on the inner wall of the conversion frame, and each shaft fixing frame is provided with a synchronous docking bushing adapted to the separate drive module; a worm gear two is fixed on the other end of the synchronous docking bushing near the rectangular hole; and a shaft seat two is suspended below the shaft fixing frame on the same side, a horizontal shaft two is rotatably connected to the middle of the shaft seat two, and a worm gear disk two that meshes with the worm gear two is fixed to the end of the horizontal shaft two, and a connecting rod is rotatably connected to the surface of the worm gear disk two near the circumferential edge, and the other end of the connecting rod is rotatably connected to the top of the driven rocker arm; thus, the rotational force output by the separate drive module can be converted into the rotation of the worm gear disk two, thereby driving the operation of the reciprocating push mechanism.

[0011] Preferably, the separate drive module includes a motor base fixed to the upper surface of the bearing housing, and a geared motor is fixed to the top of the motor base. The top of the output shaft of the geared motor is fixed with an anti-torsion sleeve with an opening facing the conversion frame via a coupling.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] In this embodiment, refer to Figure 1-10 An exercise device for bedridden patients includes a main frame 1 with a rectangular frame structure adapted to the size of the bed surface. A pad 8 is fixed to the upper surface of the main frame 1 near the foot of the bed, and a backrest 5 is rotatably connected to the upper surface of the main frame 1 near the other end. When the backrest 5 is laid flat, it and the pad 8 together completely cover the upper surface of the main frame 1. A plurality of crossbeams 101 parallel to the short sides of the main frame 1 are fixed between the two long sides of the main frame 1. Two symmetrical bearing seats 11 are fixed at the lower center of the main frame 1 below the pad 8, and the two bearing seats 11 are rotatable. Two coaxial transmission tubes 12 with the same inner and outer diameters are connected; a conversion frame 2 with a hexagonal prism shape is fixed between the two transmission tubes 12; the conversion frame 2 is a horizontally placed tubular structure; a rectangular hole 201 is opened on one side of the conversion frame 2, and a rolling and pressing mechanism 7 protruding from the surface of the conversion frame 2 is provided in the rectangular hole 201; a positioning hole 6 is opened in the middle of the backrest 5 after it is laid flat, which engages with the upward-facing plane of the conversion frame 2; and when any outer side of the conversion frame 2 is rotated to the uppermost horizontal position, its surface is flush with the upper surface of the backrest 5. Specifically, by setting a rotating connection to the conversion frame 2 below the positioning hole 6, and with its different side settings, when exercise and massage are needed, simply rotate the side where the rolling and pressing mechanism 7 is located to the positioning hole 6. After the exercise is over, rotate one side of the plane of the conversion frame 2 into the positioning hole 6 to keep the bed surface flat and free of protrusions.

[0021] In this invention, symmetrical lifting device through holes 102 are respectively opened on both sides of the main frame 1 near the lower part of the backrest plate 5, and a backrest lifting device 3 is provided on the lower surface of the main frame 1 below the lifting device through holes 102; by using the backrest lifting device 3, when the position of the conversion frame 2 is changed, the backrest lifting device 3 can be flipped up at a certain angle so that the conversion frame 2 can rotate smoothly.

[0022] Reference Figures 5-6 A driven worm gear 10 is fixed to the end of a transmission tube 12 away from the pad 8, and the driven worm gear 10 is located at the end away from the conversion frame 2. A drive shifting motor 4 is fixed below the crossbeam 101 near the driven worm gear 10, and a worm gear 1 that meshes with the driven worm gear 10 is fixed to the top of the output shaft of the drive shifting motor 4. Spoke support rods 203 that are centrally symmetrically distributed are fixed to the outer circumference of the opposite ends of the two transmission tubes 12. The spoke support rods 203 are used to fix the transmission tubes 12 and the conversion frame 2. By controlling the rotation of the worm gear 1, the conversion frame 2 can be rotated as a whole. After the drive shifting motor 4 stops, the conversion frame 2 cannot drive the worm gear 1 to rotate in the opposite direction, so it has a rapid positioning function.

[0023] Reference Figures 9-10The rolling mechanism 7 includes cantilever rods 14 fixed to the inner wall of the conversion frame 2, extending horizontally towards the center from both sides near the rectangular hole 201. Two parallel, upward-opening grooved slide rails 24 are fixed to opposite ends of the four cantilever rods 14. A convex slider 708 is slidably connected to each of the two grooved slide rails 24. A Y-shaped bracket 706 is fixed to the end of each convex slider 708 away from the bottom of the groove. The two Y-shaped brackets 706 are symmetrical, and a barrel-shaped slide 705 with the same upward-opening structure is fixed between the bottom ends of the two Y-shaped brackets 706. A bumping bracket 701 extending towards the center of the rectangular hole 201 is slidably connected to the top opening of the slide 705. Furthermore, two compression springs 707 are fixed between the bottom end of the bump support 701 and the bottom of the barrel; hinged locking positions are provided on both sides of the bump support 701 near the top and on the top of the Y-shaped support 706 on the same side; and symmetrical massage rollers 703 are provided on both sides of the bump support 701 near the top, with shaft seats 702 at both ends of the massage rollers 703 that are adapted to the hinged locking positions; through the provided rolling and pressing mechanism 7, during use, simply move the slide barrel 705 back and forth along the extension direction of the grooved slide rail 24 to allow the upward-lifted massage rollers 703 to roll under the body, thereby stimulating the back muscles and helping to restore muscle function.

[0024] Reference Figure 6 , Figures 8-10 The bump support 701 has protruding rods 704 fixed on both sides near the top, and two parallel wave guide rails 13 are fixed between the two ends of the rectangular hole 201 and located on both sides of the bump support 701. The two protruding rods 704 are slidably connected above the wave guide rails 13 on both sides. With the wave guide rails 13 and the two protruding rods 704, the massage rollers 703 on both sides can move forward in an up-and-down motion in the middle when sliding back and forth, in conjunction with the traction of the compression spring 707, forming an intermittent squeezing massage.

[0025] Reference Figures 6-7 The inner wall of the conversion frame 2 is provided with a reciprocating pushing mechanism located below the slide barrel 705. The reciprocating pushing mechanism includes sliding bearings 23 embedded in the openings of two transmission pipes 12. The same reciprocating push rod 16 is slidably connected between the two sliding bearings 23. A rack is welded to the outer wall of the reciprocating push rod 16. An L-shaped fixing rod 22 is fixed between the outer wall of the reciprocating push rod 16 and the slide barrel 705. The pushing and pulling force is transmitted through the L-shaped fixing rod 22 to drive the operation of the rolling and pressing mechanism 7. An H-shaped support frame 17 extending to the middle of the reciprocating push rod 16 is fixed to the inner wall of the conversion frame 2. A horizontal shaft 1 perpendicular to the rack is provided at the top of the H-shaped support frame 17. A driven swing rod 20 and a coaxial swing gear 21 meshing with the rack are fixed on the horizontal shaft 1. To achieve the reciprocating movement of the reciprocating push rod 16, it is only necessary to control the driven swing rod 20 to swing around the horizontal shaft 1 within a certain range.

[0026] Reference Figure 7 A separate drive module 9 is provided on the upper surface of the bearing seat 11 away from the L-shaped fixed rod 22; and multiple shaft fixing brackets 15 are fixed on the inner wall of the conversion frame 2 in a centrally symmetrical distribution, and each shaft fixing bracket 15 is provided with a synchronous docking bushing 18 adapted to the separate drive module 9; a worm gear 2 is fixed on the other end of the synchronous docking bushing 18 near the rectangular hole 201; and a shaft seat 2 is suspended below the shaft fixing bracket 15 on the same side, a horizontal shaft 2 is rotatably connected in the middle of the shaft seat 2, and a worm gear disk 2 19 that meshes with the worm gear 2 is fixed at the end of the horizontal shaft 2, and a connecting rod is rotatably connected to the surface of the worm gear disk 2 19 near the circumferential edge, and the other end of the connecting rod is rotatably connected to the top of the driven rocker arm 20; with this arrangement, the rotational force output by the separate drive module 9 can be converted into the rotation of the worm gear disk 2 19, thereby driving the operation of the reciprocating push mechanism.

[0027] Reference Figures 7-8 The separate drive module 9 includes a motor base 901 fixed to the upper surface of the bearing housing 11, and a geared motor 902 fixed to the top of the motor base 901. The top of the output shaft of the geared motor 902 is fixed with an anti-torsion sleeve with an opening facing the conversion frame 2 through a coupling. A synchronous moving shaft 904 is slidably sleeved at the opening of the anti-torsion sleeve. A permanent magnet ring 905 is fixed to the outer circumference of the synchronous moving shaft 904. An L-shaped bracket is fixed to the side of the motor base 901 near the conversion frame 2, and an electromagnet 903 is fixed to the top of each L-shaped bracket. When the electromagnet 903 is energized, it can push the synchronous moving shaft 904 with the permanent magnet ring 905 fixed to it into the corresponding synchronous docking shaft sleeve 18 to form torque transmission.

[0028] Reference Figure 6 and Figure 8 The conversion frame 2 has a strip-shaped sweeping hole 202 on the side away from the rectangular hole 201. The strip-shaped sweeping hole 202 corresponds to another shaft fixing bracket 15. The shaft fixing bracket 15 has a driving pinion fixed on the shaft of the synchronous docking bushing 18. The conversion frame 2 is rotatably connected to a sweeping roller 25. Multiple hammers are fixed on the outer circumference of the sweeping roller 25. The roller head end of the sweeping roller 25 is fixed with a driven gear 26 that meshes with the pinion. By using the sweeping roller 25, the mode can be switched to hammering mode when switching modes.

[0029] Reference Figure 6 The side of the conversion frame 2 away from the rectangular hole 201 has a ventilation hole 204; at the end of the massage, the side with the ventilation hole 204 can be rotated up to allow for perspiration. Working principle: When using this device, to exercise, first control the backrest lifter 3 to raise the backrest 5 to an appropriate angle, with the minimum angle not affecting the rotation of the conversion frame 2. This angle is determined by the number of design surfaces of the conversion frame 2 in actual production. When the side equipped with the rolling and pressing mechanism 7 rotates to face directly upward, stop the rotation of the drive shift motor 4. Then slowly lower the backrest 5 until the positioning hole 6 engages the top of the conversion frame 2. Then, control the two electromagnets 903 in the separate drive module 9 to be energized to complete the docking of the synchronous moving shaft 904 and the synchronous docking sleeve 18. Then start the reduction motor 902, which drives the reciprocating push mechanism to run, and then drives the rolling and pressing mechanism 7 to roll back and forth on the back. When the wave guide rail 13 and the two protruding rods 704 slide back and forth, in conjunction with the traction of the compression spring 707, the massage rollers 703 on both sides can move forward in a state of up and down in the middle, forming an intermittent squeezing massage. When switching to the sweeping roller 25, the roller head end of the sweeping roller 25 is fixed with a driven gear 26 that meshes with the pinion; thus, the hammer continuously pounds the back of the body; at the end of the massage, the side with the ventilation hole 204 is rotated up to allow for sweating.
