Lower limb massager

Abstract

A lower limb massager, comprising a main unit, a massage mechanism, an adjustment frame, a positioning mechanism, and an unlocking mechanism. The unlocking mechanism comprises a rotation control member rotatably assembled in the middle of the adjustment frame and at least partially extending out from the outer side of the adjustment frame, and two thread ropes arranged inside the adjustment frame and having a first end fixedly connected to the rotation control member and a second end fixedly connected to a movable locking member on the corresponding side. The thread ropes are wound by means of rotating the rotation control member, so that the thread ropes pull the movable locking member to separate a clamping protrusion from an insertion groove, so as to achieve unlocking, and the rotation control member is released, thereby releasing the wound thread ropes under the action of an elastic member. The unlocking mechanism achieves unlocking by means of winding the thread ropes by the rotation control member, and the number of parts is small, thereby simplifying the structure, reducing the manufacturing cost and assembly difficulty, and improving the smoothness of adjustment, achieving good stability and high reliability, reducing the failure rate, and prolonging the service life.

[0001] This utility model relates to the field of sports equipment technology, specifically to a lower limb massager that can be adjusted at multiple angles. Background Technology

[0002] This patent relates to a lower limb massager, comprising a main unit and an adjustment frame. The main unit has two massage chambers, each equipped with a massage mechanism. The adjustment frame is rotatably connected to both sides of the main unit. A positioning mechanism and an unlocking mechanism are configured between the adjustment frame and the main unit. The positioning mechanism allows the main unit to be positioned at its operating angle, while the unlocking mechanism allows the positioning mechanism to be released, enabling the adjustment frame to rotate relative to the main unit. In one application, the adjustment frame can be used as a handle when it is vertical relative to the main unit.

[0003] CN205459772U discloses a foot massager with a multi-angle adjustable support frame. The unlocking mechanism is a push-button transmission device, including two push buttons, two racks, one gear, two slide rails, two adjusting bolts, two connecting boxes, and two brake cables. The gear is located at the transverse center of the support frame. The two push buttons, two racks, one gear, two slide rails, two adjusting bolts, two connecting boxes, and two brake cables are arranged symmetrically left and right around the gear. The push buttons are pushed and connected to the racks, the racks are slidably connected to the slide rails, and the gear meshes with the racks above and below it. One end of the rack is threaded to the adjusting bolt, the other end of the adjusting bolt is threaded to the connecting box, the other end of the connecting box is fixedly connected to the brake cable, and the other end of the brake cable is fixedly connected to a toothed pin. Because the unlocking mechanism contains multiple components, the transmission mechanism is complex, increasing manufacturing costs and assembly difficulty. The use of multiple components increases the failure rate, affecting stability and service life.

[0004] Utility Model Content

[0005] The purpose of this invention is to solve the problems in the existing technology of multi-angle adjustable lower limb massager unlocking mechanism, which contains multiple components, has a complex transmission mechanism, high manufacturing cost and assembly difficulty, and the coordination of multiple components affects stability and service life.

[0006] The solution adopted in this application is:

[0007] A lower limb massager includes a main unit, an adjustment frame, a positioning mechanism, and an unlocking mechanism. The main unit has a massage mechanism. The adjustment frame has two sides close together with connecting ends that are rotatably connected to the two sides of the main unit. The positioning mechanism includes a positioning plate fixed to the main unit and having several radial slots along its edges, and movable locking members movably mounted on both sides of the adjustment frame. The movable locking members have one or more latching protrusions at their ends that engage with the slots, and an elastic member that acts on the movable locking members to reset them toward the positioning plate. The unlocking mechanism includes a rotary control rotatably mounted on the adjustment frame and having a control portion extending at least partially out of the adjustment frame, and two cords arranged inside the adjustment frame, with the first end coupled to the rotary control and the second end fixed to the movable locking members on corresponding sides. By rotating the rotary control, the cords are wound up, pulling the movable locking members to disengage the latching protrusions from the slots, thus unlocking the device. The rotary control is then released by the elastic member, releasing the wound cords.

[0008] The unlocking mechanism of this application unlocks by rotating the control to rewind the rope. It has fewer parts, simplifies the structure and transmission mechanism, reduces manufacturing costs and assembly difficulty, improves the smoothness of adjustment, has good stability and high reliability, reduces the failure rate, and increases service life.

[0009] Furthermore, the first ends of the two ropes are connected to the adjustment frame, and the rotary control is designed to drive the two ropes when rotated. Through the rotary control, users can easily pull, tighten, or release the ropes.

[0010] Furthermore, the first ends of the two ropes are connected to the rotation center of the adjustment frame corresponding to the rotary control. The rotary control, offset from the rotation center, has a drive unit positioned corresponding to the two ropes. This design ensures that the first ends of the two ropes are securely connected to the adjustment frame, thus guaranteeing the reliability of the rope connection. Under normal conditions, the rotary control is not subjected to force and remains stable. It only rotates to drive the ropes when operation is required, achieving precise control. The offset design of the drive unit from the rotation center increases the torque driving the ropes, making operation easier.

[0011] Furthermore, the adjustment frame has a shaft protrusion for mounting the rotation control. The first ends of the two ropes are fixed to the shaft protrusion by hanging. The rotation control has several protrusions offset from the rotation center, and a drive groove is formed between the protrusions for the two ropes to pass through. The two sides of the drive groove constitute the drive part. The shaft protrusion serves to rotatably connect to the rotation control, while ensuring that the first ends of the ropes are firmly hung, enhancing the reliability of the connection. In addition, the protrusions adopt an offset design to form a drive groove for the ropes to pass through, and the two sides of the drive groove constitute the drive part.

[0012] As an alternative, the adjustment frame has a shaft protrusion for mounting a rotation control. The first ends of the two ropes are fixed to the shaft protrusion by hanging. The rotation control has a protrusion at the offset rotation center. The protrusion has a drive groove for the two ropes to pass through. The two sides of the drive groove are configured as the drive part.

[0013] Furthermore, the axial protrusion is located on the inner top wall of the adjusting frame, and the rotary control is installed on the lower side of the two ropes through the shaft hole, while the drive groove is engaged on the outer side of the two ropes. This design allows the first ends of the two ropes to be limited by the rotary control, thereby simplifying the connection structure.

[0014] Furthermore, the outer side of the positioning plate has a folded portion, and the folded portion has several indirectly arranged slots. Furthermore, a structural ring is provided at the end of the folded portion. The arrangement of the folded portion and the structural ring serves a reinforcing function, increasing the engagement distance with the locking protrusion, and the structural ring effectively prevents the locking protrusion from disengaging from the slot.

[0015] Furthermore, the adjustment frame includes a housing and a reinforcing frame fixedly mounted within the housing. The reinforcing frame extends to the connecting end. Shaft seats are constructed on both sides of the main unit. The positioning plate is mounted on the outside of the shaft seats through a central hole. The reinforcing frame has shaft holes, which are rotatably connected to the shaft seats via a axial protrusion connector. The reinforcing frame serves to connect the adjustment frame and the main unit, and also bears the load.

[0016] Furthermore, one end of the elastic element is connected to the movable locking element, and the other end is connected to the reinforcing frame.

[0017] Furthermore, the rotary control extends out onto the side of the adjustment frame that faces the user when in use. Using this design, when the adjustment frame is supported on the ground, the extended portion of the rotary control is positioned on the upper side, facilitating user operation.

[0018] Furthermore, at least part of the control unit is constructed in an arc shape. This design improves the ease and comfort of operation for the user. Attached Figure Description

[0032] [Corrected according to Article 91, July 21, 2025] Referring to Figures 1 to 13, one embodiment of the lower limb massager of this application includes a main unit 1, a massage mechanism 2, an adjustment frame 3, a positioning mechanism 4, and an unlocking mechanism 5; the main unit 1 has two massage chambers 100 spaced apart; the massage mechanism 2 is installed on the main unit 1 and acts on the massage chambers 100; the two sides of the adjustment frame 3 are relatively close to each other and the two ends are configured as connecting ends 3.1, which are rotatably connected to the two sides of the main unit 1; the positioning mechanism 4 includes a positioning plate 4.1 fixed to the main unit 1 and having a plurality of radial slots 4.10 on its edge, and a movable locking member 4.2 movably installed on both sides of the adjustment frame 3, the end of the movable locking member 4.2 having one or more latching protrusions 4 that cooperate with the slots 4.10. 21, and an elastic element 4.3 acting on the movable locking member 4.2 to reset it toward the positioning plate 4.1; the unlocking mechanism 5 includes a rotary control 5.1 rotatably mounted in the middle of the adjusting frame 3 and having a control part 5.1' extending at least partially out of the outside of the adjusting frame 3, and two ropes 5.2 arranged inside the adjusting frame 3 with their first ends 5.21 coupled to the rotary control 5.1, specifically, the first end is fixed to the rotary control 5.1, and the second end 5.22 is fixed to the corresponding side of the movable locking member 4.2. By rotating the rotary control 5.1, the ropes 5.2 are wound up and the movable locking member 4.2 is pulled to make the locking protrusion 4.21 disengage from the slot 4.10 to achieve unlocking. The rotary control 5.1 releases the wound ropes 5.2 under the action of the elastic element 4.3.

[0033] When the angle of the main unit 1 needs to be adjusted, the user rotates the unlocking mechanism 5 via the control unit 5.1' to wind up the cord 5.2 and pulls the movable locking piece 4.2 to disengage the latch 4.21 from the slot 4.10. At this point, the adjustment frame 3 can be rotated relative to the main unit 1 to the desired angle, such as the horizontal angle shown in Figure 3 or the tilted angle shown in Figure 4. In some embodiments, a vertical angle can be configured, as shown in Figure 1. In this case, the adjustment frame 3 can be used as a lift for the lower limb massager, making it convenient for the user to move. After adjusting the angle of the adjustment frame 3, the rotation control 5.1 is released. Under the action of the elastic element 4.3, the rotation control 5.1 rotates in the opposite direction, releasing the wound portion of the cord 5.2. The latch 4.21 of the movable locking piece 4.2 then locks the adjustment frame 3 at the selected angle within the corresponding slot 4.10.

[0034] Therefore, in order to increase the positioning angle range, multiple slots 4.10 can be constructed around the center of the positioning disk 4.1. It should be noted that they are generally constructed at equal intervals, which facilitates the cooperation of the card protrusion 4.21.

[0035] To increase the stability and reliability of the locking mechanism, there are multiple locking protrusions 4.21, such as the three shown in the attached drawings of this application. The three locking protrusions 4.21 are spaced apart and cooperate with the three slots 4.10 on the positioning plate 4.1.

[0036] The unlocking mechanism 5 of this application unlocks by rotating the control 5.1 to wind up the rope 5.2. It has fewer parts, simplifies the structure, reduces manufacturing costs and assembly difficulty, improves the smoothness of adjustment, has good stability and high reliability, reduces the failure rate, and increases service life.

[0037] The rope 5.2 in this application is a high-strength rope, such as a steel wire rope, or of course, other existing ropes that can meet the strength requirements.

[0038] As shown in Figures 1 to 4 and Figures 9 to 11, the control part 5.1′ of the rotation control 5.1 extends outward through the control hole 300 on the adjustment bracket 3. It is used to rotate the rotation control 5.1 via the control part 5.1′ when unlocking.

[0039] Referring to Figures 1 to 4, the portion of the rotary control 5.1 extending out of the adjustment frame 3 faces the user when in use. Using the above solution, when the adjustment frame 3 is supported on the ground, the portion of the rotary control 5.1 extending out is located on the upper side, making it convenient for the user to operate.

[0040] As shown in Figures 1, 10 and 11, the adjustment frame 3 is provided with a support part 3.4′ that contacts the ground, which can be locally heightened, such as by thickening the bent parts on both sides.

[0041] Referring to Figures 1 to 4, and Figures 9 to 11, the control part 5.1′ is at least partially constructed in an arc shape. This design improves the ease and comfort of user operation. As shown in the figures, the outer periphery of the control part 5.1′ is arc-shaped. In some embodiments, the outer periphery of the control part 5.1′ can be constructed with an anti-slip structure, such as textures or uneven surfaces, to increase friction during user operation, better transmit the user's driving force, and prevent slippage.

[0042] Referring to Figures 5, 9 to 13, the first ends 5.21 of the two ropes 5.2 are connected to the adjusting frame 3. The rotation control 5.1 is constructed with a driving part 5.11 that acts on the two ropes 5.2 when rotated. Through the rotation control 5.1, the user can easily perform operations such as pulling, tightening or releasing the ropes 5.2.

[0043] In some embodiments, the first ends 5.21 of the two cords 5.2 are connected to the rotation center of the adjusting frame 3 corresponding to the rotation control 5.1. The rotation control 5.1 is biased towards the rotation center and has a drive unit 5.11 corresponding to the two cords 5.2. This design ensures that the first ends 5.21 of the two cords 5.2 are firmly connected to the adjusting frame 3, thereby guaranteeing the reliability of the cord connection. Under normal conditions, the rotation control 5.1 is not subjected to force and remains stable. It only drives the cords 5.2 to move by rotation when operation is required, achieving precise control. The design of the drive unit 5.11 biased towards the rotation center increases the torque of driving the cords 5.2, making operation easier.

[0044] As shown in Figure 13, both the first end 5.21 and the second end 5.22 of the rope 5.2 are provided with hanging rings. If steel wire rope hanging rings are used, the bent end of the rope 5.2 can be clamped by a metal cylinder. Of course, other existing technologies for fixing the end of the rope 5.2 to form hanging rings can also be used, such as welding, connectors, etc.

[0045] Referring to Figures 9 to 13, the adjusting frame 3 has a shaft protrusion 3.2 for mounting the rotating control 5.1. The first ends 5.21 of the two ropes 5.2 are fixed to the shaft protrusion 3.2 by hanging. The rotating control 5.1 has several protrusions 5.10 offset from the rotation center. A drive groove 5.11' for the two ropes 5.2 to pass through is formed between the protrusions 5.10. The two sides of the drive groove 5.11' constitute the drive part 5.11. The shaft protrusion 3.2 serves to rotatably connect the rotating control 5.1 and ensure that the first ends 5.21 of the ropes 5.2 are firmly hung, enhancing the connection reliability. In addition, the protrusions 5.10 adopt an offset design to form the drive groove 5.11' for the ropes 5.2 to pass through. The two sides of the drive groove 5.11' constitute the drive part 5.11. Specifically, the rotating control 5.1 is rotatably connected to the shaft protrusion 3.2 through the shaft hole 50. The drive slot 5.11' has drive sections 5.11 on both sides, which allows the rotary control 5.1 to rotate in both directions to wind up the rope 5.2, providing a better user experience.

[0046] In other embodiments (not shown), the adjustment frame 3 is constructed with a shaft protrusion 3.2 for mounting the rotation control 5.1. The first ends of the two ropes 5.2 are fixed to the shaft protrusion 3.2 by hanging. The rotation control 5.1 is provided with a protrusion at the offset rotation center. The protrusion is provided with a drive groove for the two ropes 5.2 to pass through. The two sides of the drive groove are constructed as the drive part.

[0047] Referring to Figures 9 to 13, the shaft protrusion 3.2 is constructed on the inner top wall of the adjusting frame 3. The rotation control 5.1 is installed on the lower side of the two ropes 5.2 through the shaft hole 50, and the drive groove 5.11' is engaged on the outer side of the two ropes 5.2. This design allows the first end 5.21 of the two ropes 5.2 to be limited by the rotation control 5.1, thereby simplifying the connection structure.

[0048] In the embodiment shown in Figures 9 and 10, the protrusion 5.10 is composed of multiple arc-shaped convex walls, and the drive groove 5.11' is formed by the gap between two adjacent arc-shaped convex walls. The protrusion 5.10 is constructed on the arc-shaped convex walls. When unlocking, the cord 5.2 is driven by the side of the drive groove 5.11'. Since the first end 5.21 and the second end 5.22 are fixed, when the rotation control 5.1 is rotated, the cord 5.2 is wound around the outside of the arc-shaped convex walls.

[0049] A first annular wall 3.3 is constructed on the inner wall of the adjusting frame 3, located inside the protrusion 5.10. The first annular wall 3.3 has a channel 3.30 for the cable 5.2 to pass through, located opposite to the extending direction of the adjusting frame 3. Under normal conditions, the drive groove 5.11' corresponds to the channel 3.30, meaning the drive part 5.11 corresponds to the outer side of the channel 3.30. This design makes operating the rotating control 5.1 smoother during unlocking.

[0050] In some embodiments, a second annular wall 3.4 is constructed radially spaced outside the first annular wall 3.3. The height of the second annular wall 3.4 is lower than that of the first annular wall 3.3. The cord 5.2 passes over the top of the second annular wall 3.4 and restricts the position of the cord 5.2 through the top of the second annular wall 3.4, thereby improving the smoothness of operating the rotary control 5.1.

[0051] The protrusion 5.10 is inserted into the space between the first ring wall 3.3 and the second ring wall 3.4, and the space between the first ring wall 3.3 and the second ring wall 3.4 is designed to be greater than the wall thickness of the protrusion 5.10. The rotating control 5.1 rotates the winding rope 5.2, which is then housed within the space between the protrusion 5.10 and the first ring wall 3.3 and the second ring wall 3.4. Specifically, the radial width between the first ring wall 3.3 and the second ring wall 3.4 is preferably designed to be greater than the sum of the wall thickness of the protrusion 5.10 and the diameter of the rope 5.2.

[0052] Referring to Figures 5 to 9 and Figure 12, the adjusting frame 3 includes a housing 3' and a reinforcing frame 3.4 fixedly mounted within the housing 3'. The reinforcing frame 3.4 extends to the connecting end 3.1. The main unit 1 has bearing seats 1.1 on both sides. A positioning disc 4.1 is mounted on the outside of the bearing seat 1.1 through a central hole 40. The reinforcing frame 3.4 has a shaft hole 3.40, which is rotatably connected to the bearing seat 1.1 via a shaft-mounted connecting seat 1.12. The reinforcing frame 3.4 serves to connect the adjusting frame 3 and the main unit 1 and to bear force. The first end 5.21 of the elastic element 4.3 is connected to the movable locking element 4.2, and the second end 5.22 is connected to the reinforcing frame 3.4, such as by hanging on the hook portion of the reinforcing frame 3.4. In one embodiment, the reinforcing frame 3.4 is made of sheet metal, and the movable locking element 4.2 is also made of sheet metal, slidingly engaging with the reinforcing frame 3.4. It should be noted that the specific assembly structure of the reinforced frame 3.4 and the movable locking component 4.2 is not an improvement of this application, and can be achieved by referring to existing technical means.

[0053] Referring to Figures 10 and 11, the outer shell 3' includes a base shell portion 3.1' and a first inner cover 3.2' and a second inner cover 3.3' located outside the adjusting frame 3. The shaft protrusion 3.2, the first annular wall 3.3, and the second annular wall 3.4 are integrally formed on the top wall of the base shell portion 3.1'. Two reinforcing frames 3.4 are respectively connected to both sides of the base shell portion 3.1', for example, by screws. To enhance the connection strength, positioning protrusions and positioning holes are constructed between the two reinforcing frames 3.4 and the base shell portion 3.1'. The first inner cover 3.2' and the second inner cover 3.3' correspond to the inner side of the middle portion and the inner side portion of the base shell portion 3.1', respectively. The two ropes 5.2 and the rotation control 5.1 are assembled to the shaft protrusion 3.2 and then limited by the first inner cover 3.2'. The first inner cover 3.2' and the second inner cover 3.3' are connected and fixed to the base shell portion 3.1' by screws or other means.

[0054] Referring to Figures 1 to 5, the sidewalls and bottom wall of the massage cavity 100 are covered with a flexible liner 2.4. The massage mechanism 2 includes a foot massage mechanism 2.1 installed at the bottom of the massage cavity 100, a lateral massage mechanism 2.2 installed on the side of the massage cavity 100, and a drive mechanism 2.3. One embodiment of the foot massage mechanism 2.1 is a cam-type massage mechanism, and one embodiment of the lateral massage mechanism 2.2 is an airbag massage mechanism. Correspondingly, the drive mechanism 2.3 includes a motor and a transmission mechanism, as well as an air pump for controlling the airbag massage mechanism. It should be noted that the massage mechanism 2 is not an improvement of this application and will not be described in detail.

[0055] Referring to Figures 6 to 8, the outer side of the positioning disk 4.1 has a folded portion 4.11, which has several indirectly arranged slots 4.10. A structural ring 4.111 is formed at the end of the folded portion 4.11. The arrangement of the folded portion 4.11 and the structural ring 4.111 provides reinforcement, increases the engagement distance with the latching protrusion 4.21, and effectively prevents the latching protrusion from disengaging from the slot. In one embodiment, the positioning disk 4.1 is made of metal.

[0056] Referring to Figures 5 to 9 and Figure 12, the main unit 1 has connecting seats 1.1' on both sides. The positioning plate 4.1 is installed to the connecting seat 1.1' through a connector. The positioning plate 4.1 has a clearance hole 4.10' in the middle. The shaft seat 1.1 is connected to the connecting seat 1.1 through the shaft hole 3.40 of the reinforcing frame 3.4 and the clearance hole 4.10'. The outer side of the shaft seat 1.1 has a protruding edge with a limit clearance hole 4.10'.

[0057] Based on the disclosure and teachings of the above specification, those skilled in the art to which this utility model pertains can make changes and modifications to the above embodiments. This utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model.
