Description
Technical Field
[0001] This utility model relates to the field of massage chair technology, and more specifically, to a manual armrest adjustment mechanism for a massage chair. Background Technology
[0002] Existing massage chairs typically have armrests on both sides, and these armrests are usually fixedly connected to the chair, meaning they cannot be adjusted relative to the chair. However, existing solutions that allow armrest adjustment relative to the chair, such as the massage chair armrest door opening and closing connection structure disclosed in CN220607873U, include a chair frame with an armrest door on at least one side. The chair frame and armrest door are movably connected by at least one set of opening and closing mechanisms. Each opening and closing mechanism includes two first support seats fixedly installed on the side of the chair frame and on the inner rear end of the armrest door, and two connecting rods connected to the two first support seats. One end of each connecting rod is rotatably connected to the two first support seats, and the other end of each connecting rod is rotatably equipped with a slider. The sliders at the other end of each connecting rod are slidingly connected to the two first support seats in a linear direction, and the middle of the two connecting rods is rotatably connected. A damping positioning mechanism is also connected between the chair frame and the armrest door. This invention provides a simple massage chair armrest door opening and closing connection structure that makes the armrest door opening and closing process smoother and safer. Even if the armrests are adjustable relative to the massage chair, the armrests as a whole open and close relative to the chair frame; the individual components of the armrests themselves cannot be moved or adjusted relative to each other. Utility Model Content
[0003] This invention overcomes the shortcomings of the prior art. Its structure is reasonably designed, allowing the movable armrest board to open relative to the fixed armrest board, providing greater support for the human arm and making it more convenient to get on and off the massage chair.
[0004] To achieve the above objectives, the present invention provides the following technical solution: A manual armrest adjustment mechanism for a massage chair includes an armrest fixing plate, an armrest movable plate movably opening and closing on the armrest fixing plate, and a locking structure between the armrest movable plate and the armrest fixing plate. When the armrest movable plate is closed relative to the armrest fixing plate, the locking structure locks the armrest movable plate to the armrest fixing plate. A movable opening and closing structure is provided between the armrest movable plate and the armrest fixing plate, allowing the armrest movable plate to open or close relative to the armrest fixing plate. The movable opening and closing structure includes an elastic force-accumulating element, so that when the locking structure is unlocked, the elastic force-accumulating element causes the armrest movable plate to open relative to the armrest fixing plate.
[0005] By adopting the above technical solution, when the locking structure is locked, the movable armrest panel closes and locks onto the fixed armrest panel. At this time, the elastic storage component stores force. When the locking structure is unlocked, the elastic force of the elastic storage component causes the movable armrest panel to open upward relative to the fixed armrest panel. This allows the armrest supporting the user's arm to be adjusted in height to meet the needs of different users. That is, when the movable armrest panel is closed relative to the fixed armrest panel, the user's arm can only be placed at the height of the fixed armrest panel. After the movable armrest panel is opened relative to the fixed armrest panel, the user's arm can be supported on the opened movable armrest panel, at which point the movable armrest panel is at different height positions relative to the fixed armrest panel.
[0006] Preferably, the movable armrest panel opens and closes relative to the fixed armrest panel along the height direction or along the length of the human arm.
[0007] By adopting the above technical solution, the opening direction of the armrest movable plate is limited. When the armrest movable plate is opened along the length of the human arm, the armrest movable plate will also change in height relative to the armrest fixed plate.
[0008] Preferably, the movable opening and closing structure further includes a hinge seat fixed to the movable handrail plate, a slide groove installed on the fixed handrail plate, and a rotating rod with one end hinged to the hinge seat and the other end slidably disposed in the slide groove. The rotating rod can close or open relative to the slide groove. The elastic storage element is configured as a torsion spring, with one end of the torsion spring connected to or abutting the movable handrail plate and the other end of the torsion spring connected to or abutting the rotating rod.
[0009] By adopting the above technical solution, the torsion spring is used as an elastic storage component, and the rotating rod drives the opening or closing of the handrail movable plate. When the handrail movable plate is closed, the torsion spring stores force and does not provide elastic force when the handrail movable plate is open. After the handrail movable plate is opened, the handrail movable plate is pressed down to close with the handrail fixed plate by manual operation.
[0010] Preferably, rollers are provided on both sides of the end of the rotating rod near the slide groove. The rollers are slidably disposed in the slide groove. The rotating rod can be partially located in the slide groove. The movement of the rollers is restricted by the slide groove in the height direction of the slide groove, and the rollers slide along the length direction of the slide groove.
[0011] By adopting the above technical solution, the roller arrangement reduces the sliding friction between the rotating rod and the slide groove, and the rotating rod can be partially located in the slide groove, that is, the opening width of the slide groove is greater than the diameter of the rotating rod. In this way, the movable handrail plate can be completely closed to the fixed handrail plate, and the roller is confined in the slide groove, and the roller can only slide along the length direction of the slide groove.
[0012] Preferably, the hinge seat is provided with a hinge shaft passing through the rotating rod, and a torsion spring seat is provided on one side of the hinge shaft and the torsion spring is sleeved on the torsion spring seat.
[0013] By adopting the above technical solution, the hinge shaft, as a mature existing technology of hinge structure, is set through the hinge seat, torsion spring seat and rotating rod. The torsion spring seat provides installation support for the torsion spring, and when the rotating rod closes relative to the slide groove, the torsion spring will rotate and store force.
[0014] Preferably, a horizontal swing mechanism is provided between the fixed handrail plate and the movable handrail plate. After the movable handrail plate is opened relative to the fixed handrail plate, the horizontal swing mechanism causes the movable handrail plate to swing relative to the fixed handrail plate along the length of the human arm.
[0015] By adopting the above technical solution, the horizontal swing structure allows the armrest movable plate to swing relative to the armrest fixed plate along the length of the human arm. This changes the position of the armrest movable plate along the length of the human arm, adapting to the support of the arm when the user is sitting in different body positions on the massage chair. Furthermore, the horizontal swing structure allows the armrest movable plate to swing relative to the armrest fixed plate towards the back of the massage chair, making it more convenient to get on and off the massage chair.
[0016] Preferably, the flat-swing structure includes a fixed mounting component fixed to the fixed plate of the handrail, a movable mounting component fixed to the movable plate of the handrail, a hinged end seat disposed on the fixed mounting component, and a hinge rod with its two ends respectively hinged to the movable mounting component and the hinged end seat.
[0017] By adopting the above technical solution, when the movable handrail plate is opened relative to the fixed handrail plate, the hinge rod will rotate and open relative to the hinge end seat. At this time, the opening force is also provided by the elastic force of the torsion spring. After the movable handrail plate is opened relative to the fixed handrail plate, the movable handrail plate can be manually operated to move. At this time, the hinge rod will continue to rotate relative to the hinge end seat at a certain angle, so that the position of the movable handrail plate can be adjusted in the direction of the human arm.
[0018] Preferably, the locking structure includes a locking hook disposed on the fixed plate of the handrail and a locking block disposed on the movable plate of the handrail.
[0019] By adopting the above technical solution, a locking structure using a locking block and a locking hook is used. The structure is simple, the locking is stable and reliable, and an unlocking button is set on the side of the armrest fixing plate or other positions of the massage chair. The unlocking button disengages the locking block from the locking hook, and then the torsion spring can open the armrest through elastic force. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figure 1-9As shown, a manual armrest adjustment mechanism for a massage chair includes an armrest fixing plate 1, an armrest movable plate 2 movably opening and closing on the armrest fixing plate 1, and a locking structure 3 between the armrest movable plate 2 and the armrest fixing plate 1. When the armrest movable plate 2 is closed relative to the armrest fixing plate 1, the locking structure 3 locks the armrest movable plate 2 to the armrest fixing plate 1. A movable opening and closing structure 4 is provided between the armrest movable plate 2 and the armrest fixing plate 1, and the armrest movable plate 2 can be opened or closed relative to the armrest fixing plate 1 through the movable opening and closing structure 4. The movable opening and closing structure 4 includes an elastic force storage member, so that when the locking structure 3 is unlocked, the elastic force storage member causes the armrest movable plate 2 to open relative to the armrest fixing plate 1.
[0024] By adopting the above technical solution, when the locking structure 3 is locked, the movable armrest plate 2 is closed and locked onto the fixed armrest plate 1. At this time, the elastic storage component will store force. When the locking structure 3 is unlocked, the elastic force of the elastic storage component will cause the movable armrest plate 2 to open upward relative to the fixed armrest. In this way, the armrest used to support the human arm can be adjusted in height to meet the needs of different users. That is, when the movable armrest plate 2 is closed relative to the fixed armrest plate 1, the human arm can only be placed in the height direction of the fixed armrest plate 1. After the movable armrest plate 2 is opened relative to the fixed armrest plate 1, the human arm can be supported on the opened movable armrest plate 2. At this time, the movable armrest plate 2 is at different height positions relative to the fixed armrest plate 1.
[0025] The movable handrail 2 opens and closes relative to the fixed handrail 1 along the height direction or along the length of the human arm, which limits the opening direction of the movable handrail 2. When the movable handrail 2 opens along the length of the human arm, the movable handrail 2 will also change relative to the fixed handrail 1 in the height direction.
[0026] Furthermore, the movable opening and closing structure 4 also includes a hinge seat 41 fixed on the movable handrail plate 2, a slide groove 42 installed on the fixed handrail plate 1, and a rotating rod 43 with one end hinged to the hinge seat 41 and the other end slidably disposed in the slide groove 42. The rotating rod 43 can close or open relative to the slide groove 42. The elastic storage element is configured as a torsion spring 44. One end of the torsion spring 44 is connected to or abuts against the movable handrail plate 2, and the other end of the torsion spring 44 is connected to or abuts against the rotating rod 43. With this configuration, the torsion spring 44 acts as an elastic storage element, and the rotating rod 43 drives the movable handrail plate 2 to open or close. When the movable handrail plate 2 is closed, the torsion spring 44 stores force and provides elastic force when the movable handrail plate 2 is open. After the movable handrail plate 2 is opened, the movable handrail plate 2 can be pressed down to close with the fixed handrail plate 1 by manual operation.
[0027] Furthermore, rollers 45 are provided on both sides of the end of the rotating rod 43 near the slide groove 42. The rollers 45 are slidably disposed in the slide groove 42. The rotating rod 43 can be partially located in the slide groove 42. The rollers 45 are restricted by the slide groove 42 to move in the height direction of the slide groove 42. The rollers 45 slide along the length direction of the slide groove 42. The arrangement of the rollers 45 reduces the sliding friction between the rotating rod 43 and the slide groove 42. Since the rotating rod 43 can be partially located in the slide groove 42, that is, the opening width of the slide groove 42 is greater than the diameter of the rotating rod 43. In this way, the movable handrail plate 2 can be completely closed to the fixed handrail plate 1, and the rollers 45 are restricted to the slide groove 42. The rollers 45 can only slide along the length direction of the slide groove 42.
[0028] The hinge seat 41 is provided with a hinge shaft that passes through the rotating rod 43. A torsion spring seat 46 is provided on one side of the hinge shaft and the torsion spring 44 is sleeved on the torsion spring seat 46. The hinge shaft is a mature existing technology for hinge structure. It passes through the hinge seat 41, the torsion spring seat 46 and the rotating rod 43. The torsion spring seat 46 provides installation support for the torsion spring 44. When the rotating rod 43 closes relative to the slide groove 42, the torsion spring 44 will rotate and store force.
[0029] Furthermore, a horizontal swing structure 5 is provided between the fixed armrest plate 1 and the movable armrest plate 2. After the movable armrest plate 2 is opened relative to the fixed armrest plate 1, the horizontal swing mechanism causes the movable armrest plate 2 to swing relative to the fixed armrest plate 1 along the length of the human arm. The horizontal swing structure 5 allows the movable armrest plate 2 to swing relative to the fixed armrest plate 1 along the length of the human arm, thus changing the position of the movable armrest plate 2 in the length of the human arm. This can adapt to the support of the arm when the user is sitting in different body positions on the massage chair. In addition, the horizontal swing structure 5 allows the movable armrest plate 2 to swing relative to the fixed armrest plate 1 towards the back of the massage chair, making it more convenient to get on and off the massage chair.
[0030] The horizontal structure 5 includes a fixed mounting part 51 fixed on the fixed armrest plate 1, a movable mounting part 52 fixed on the movable armrest plate 2, a hinge end seat 53 set on the fixed mounting part 51, and a hinge rod 54 with its two ends hinged to the movable mounting part 52 and the hinge end seat 53 respectively. When the movable armrest plate 2 is opened relative to the fixed armrest plate 1, the hinge rod 54 will rotate and open relative to the hinge end seat 53. At this time, the opening force is also provided by the elastic force of the torsion spring 44. After the movable armrest plate 2 is opened relative to the fixed armrest plate 1, the movable armrest plate 2 can be manually operated to move. At this time, the hinge rod 54 will continue to rotate a certain angle relative to the hinge end seat 53, so that the position of the movable armrest plate 2 can be adjusted in the direction of the human arm.
[0031] In addition, the locking structure 3 includes a locking hook 31 set on the armrest fixed plate 1 and a locking block 32 set on the armrest movable plate 2. The locking structure 3 using the locking block 32 and the locking hook 31 is simple in structure and has stable and reliable locking. Furthermore, an unlocking button is set on the side of the armrest fixed plate 1 or other positions of the massage chair. The unlocking button disengages the locking block 32 from the locking hook 31, and then the torsion spring 44 can open the armrest by elastic force.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
