Abstract
Description
Technical Field
[0001] The invention relates to the technical field of massage, and in particular to a massage chair frame with a variable guide rail. Background Art
[0002] In the prior art, the back of the massage chair using L-shaped rails cannot rotate relative to the seat, so the angle between the back and the seat cannot be adjusted according to the needs of the user. In the massage chair using segmented rails, although the back can rotate relative to the seat, the massage movement can only move on one rail. Summary of the invention
[0003] The present invention aims at the deficiencies of the prior art and proposes a massage chair frame with a variable guide rail, wherein the back of the massage chair frame with the variable guide rail can rotate relative to the seat, and the massage movement can move between the back and the seat.
[0004] A massage chair frame with variable guide rails, comprising a back frame and a back guide rail arranged on the back frame, a seat frame and a seat guide rail arranged on the seat frame, and a massage movement, wherein the massage movement is provided with coaxial running wheels and driving wheels arranged side by side, the back frame can rotate relative to the seat frame to drive the back guide rail to rotate relative to the seat guide rail; the bottom end of the back guide rail is provided with a back transition section, the top end of the seat guide rail is provided with a seat transition section, the back transition section and the seat transition section are hinged to each other so that the back guide rail can rotate relative to the seat guide rail; the running wheels and driving wheels on the back guide rail and the seat guide rail relative to the massage movement The wheels are provided with positioning channels and fixed racks side by side, the positioning channel accommodates the walking wheels, and the fixed racks are meshed with the driving wheels; the back transition section and the seat transition section are hinged to each other, a guide column is provided on the top of the back transition section, and a yield groove is provided on the top of the seat transition section. When the back transition section rotates relative to the seat transition section, the guide column part rotates into the yield groove to form a guide channel. The guide channel uses the back transition section and the seat transition section as the bottom plate, and the guide column and the yield groove as the top plate, so that the walking wheels are restricted by the bottom plate and the top plate in the process of passing through the guide channel.
[0005] The present invention has the following beneficial effects: by setting mutually hinged back transition section and seat transition section, and connecting the top of the back transition section and the seat transition section through guide columns and clearance grooves, a continuous guide channel is formed, so that the running wheel can pass through the guide channel to move between the back guide rail and the seat guide rail. Since the guide channel is formed by the mutually hinged back transition section and the seat transition section, and has a top plate and a bottom plate, the distance between the top plate and the bottom plate remains unchanged during the mutual rotation of the back transition section and the seat transition section, which enables the top plate and the bottom plate to always effectively limit the movement of the running wheel during the rotation process, ensuring that the running wheel can smoothly pass through the guide channel and will not accidentally fall out.

DETAILED DESCRIPTION
[0017] As shown in the figure, an embodiment of the present invention provides a massage chair frame with variable guide rails, including a back frame and a back guide rail 1 arranged on the back frame, a seat frame and a seat guide rail 2 arranged on the seat frame, and a massage movement 3, the massage movement 3 is provided with a coaxial and side-by-side running wheel 4 and a driving wheel 5, the back frame can rotate relative to the seat frame to drive the back guide rail 1 to rotate relative to the seat guide rail 2; the bottom end of the back guide rail 1 is provided with a back transition section 6, the top end of the seat guide rail 2 is provided with a seat transition section 7, the back transition section 6 and the seat transition section 7 are hinged to each other so that the back guide rail 1 can rotate relative to the seat guide rail 2; the back guide rail 1 and the seat guide rail 2 are provided with a positioning channel 8 and a fixed rack 9 side by side relative to the running wheel 4 and the driving wheel 5 of the massage movement 3, the positioning channel 8 accommodates the running wheel 4, the fixed rack 9 and the driving wheel 5 meshing; the back transition section 6 and the seat transition section 7 are hinged to each other, a guide column 10 is provided at the top of the back transition section 6, and a clearance groove 11 is provided at the top of the seat transition section 7. When the back transition section 6 rotates relative to the seat transition section 7, the guide column 10 partially rotates into the clearance groove 11 to form a guide channel 12. The guide channel 12 uses the back transition section 6 and the seat transition section 7 as the bottom plate, and the guide column 10 and the clearance groove 11 as the top plate. The walking wheel 4 is restricted by the bottom plate and the top plate during passing through the guide channel 12. By setting up a back transition section 6 and a seat transition section 7 that are hinged to each other, and connecting the tops of the back transition section 6 and the seat transition section 7 through a guide column 10 and a clearance groove 11, a continuous guide channel 12 is formed, so that the walking wheel 4 can pass through the guide channel 12 to move between the back guide rail 1 and the seat guide rail 2; since the guide channel 12 is formed by the back transition section 6 and the seat transition section 7 that are hinged to each other, and has a top plate and a bottom plate, the distance between the top plate and the bottom plate remains unchanged during the mutual rotation of the back transition section 6 and the seat transition section 7, which makes it possible for the top plate and the bottom plate to always effectively limit the movement of the walking wheel 4 during the rotation process, ensuring that the walking wheel can smoothly pass through the guide channel 12 and will not accidentally fall out.
[0018] The back transition section 6 and the seat transition section 7 are both arc-shaped, and the back transition section 6 and the seat transition section are tangent at the junction 7. Through the above arrangement, the bottom plate of the guide channel 12 is always a smooth curve, so that the walking wheel 4 can slide smoothly in the guide channel 12.
[0019] The guide post 10 and the clearance groove 11 are arranged in an arc shape concentric with the back transition section 6; the guide post 10 and the clearance groove 11 have the same radius. Through the above arrangement, during the rotation of the back transition section 6, the distance between the guide post 10 or the clearance groove 11 and the back transition section 6 remains unchanged, that is, the width of the guide channel 12 remains unchanged, so as to ensure that the running wheel 4 can pass through the guide channel 12 without getting stuck due to a reduced width or leaving the guide channel 12 due to an increased width.
[0020] It also includes a rotating rack 13; the rotating rack 13 is hinged to the same axis as the back transition section 6 and the seat transition section; when the running wheel 4 slides in the guide channel 12, the rotating rack 13 rotates to a position that meshes with the driving wheel 5 to support the driving wheel 5. If a rack that is integrated with the fixed rack 9 is used in the back transition section 6 and the seat transition section 7, when the back transition section 6 rotates, the rack at the junction of the back transition section 6 and the seat transition section 7 will bend and cannot form a smooth contact surface; while using the rotating rack 13, during the process of rotating the back transition section 6, the shape of the rotating rack 13 will not change, and its contact surface with the driving wheel 5 is always a smooth curve. It should be noted that because the shapes of the guide channel 12 and the rotating rack 13 are different, when the running wheel 4 slides in the guide channel 12, the rotating rack 13 needs to be rotated multiple times to adjust the position and keep it meshed with the driving wheel 5.
[0021] A limit block 14 is provided on the back transition section 6 and the seat transition section 7; when the rotating rack 13 rotates to a position meshing with the driving wheel 5, the limit block 14 limits the rotating rack 13 from continuing to rotate. When the rotating rack 13 rotates to a position meshing with the driving wheel 5, the limit block 14 limits the rotating rack 13 from continuing to rotate, preventing the rotating rack 13 from shaking during the process of supporting the driving wheel 5.
[0022] The two ends of the rotating rack 13 extend toward the back guide rail 1 and the seat guide rail 2 respectively to form a guide structure 15; before the running wheel 4 enters the guide channel 12, the massage mechanism 3 presses against the guide structure 15 to push the rotating rack 13 to rotate toward the position of the limit block 14. By providing the guide structure 15, the rotating rack 13 rotates to a suitable position before the running wheel 4 enters the guide channel 12. When the running wheel 4 enters the guide channel 12, the driving wheel 5 immediately engages with the rotating rack 13 to drive the running wheel 4 to continue sliding in the guide channel 12.
[0023] It also includes a back fixing plate 16 and a seat fixing plate 17; the back fixing plate 16 is fixed to the bottom end of the back guide rail 1, and the back transition section 6 is locked to the back fixing plate 16; the seat fixing plate 17 is fixed to the bottom end of the seat guide rail 2, and the seat transition section 7 is locked to the seat fixing plate 17.
[0024] The back fixing plate 16 and the seat fixing plate 17 are provided with an elastic connector 18, which is connected to the rotating rack 13. By providing the elastic connector 18, when the running wheel 4 slides on the back guide rail 1 or the seat guide rail 2, the rotating rack 13 will not rotate randomly and collide with the chair frame, and will also return to its original position after the running wheel 4 leaves the guide channel 12.
[0025] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
