Description

Technical Field

[0001] This utility model relates to the field of massage chair technology, and in particular to a double-rotating-axis side-opening structure for the armrest of a massage chair. Background Technology

[0002] Most massage chairs on the market typically include a seat, backrest, and armrests on both sides. Besides providing support for the user's arms and hands to improve comfort, the armrests also restrain the user's body, preventing falls from the sides and ensuring safety. However, the armrests can interfere with getting on and off the massage chair, making it inconvenient, especially for elderly users who may face the risk of falling.

[0003] The applicant previously applied for a utility model patent, authorized by CN219878589U, which discloses an armrest pin-type door opening structure for a massage chair, including a seat cushion, a backrest, and two armrests respectively disposed on both sides of the seat cushion. At least one armrest is rotatably disposed on the side of the seat cushion. The rear end of the armrest is rotatably connected to the lower side of the backrest or the rear side of the seat cushion. The axis of rotation of the armrest corresponds to the vertical direction. The front end of the armrest and the front side of the seat cushion cooperate to lock or unlock, so as to keep the front end of the armrest close to the front side of the seat cushion or to allow the front end of the armrest to rotate and open away from the seat cushion.

[0004] The aforementioned patent allows the armrests to rotate and open relative to the seat cushion, enabling users to sit or get off the massage chair. However, this rotation requires a large amount of space for the armrests to move and can easily trap hands, resulting in low safety. Furthermore, the armrests are locked or unlocked by two locking parts, which require considerable external force to separate or close. This makes it difficult for the weak or elderly to open or close the armrests. Summary of the Invention

[0005] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides a double-rotating-axis side-opening door structure for the armrest of a massage chair. When the armrest is opened, it occupies less space, is less likely to pinch hands, is safer, and the armrest is more convenient and labor-saving to open and close.

[0006] The technical solution of this utility model is: a double-rotating-axis side-opening structure for the armrest of a massage chair, including a seat cushion, a backrest, and armrests on both sides of the seat cushion. At least one armrest is connected to the seat cushion via a rotating shaft at its rear end and middle, which drives the armrest to move relative to the seat cushion to open the armrest. A locking structure is provided between the front end of the armrest and the seat cushion to lock or unlock the armrest.

[0007] By adopting the above technical solution, after unlocking the handrail, the handrail can be pushed outward to open the side of the handrail, making it convenient for users to go up and down. Pulling the handrail inward locks it with a locking structure. The sliding opening structure of the handrail makes it occupy less space after opening, less likely to pinch hands, and safer.

[0008] A further feature of this invention is that the pivot installed at the rear end of the armrest is arranged in a "Z" shape, and the pivot installed in the middle of the armrest is arranged in a straight line. One end of each pivot is hinged to the armrest and the other end is hinged to the seat cushion. When the armrest is opened relative to the seat cushion, both pivots are horizontally positioned between the armrest and the seat cushion. When the armrest is closed relative to the seat cushion, the Z-shaped pivot is closed between the armrest and the seat cushion, and the straight pivot is located below the seat cushion.

[0009] With the above-mentioned further configuration, a straight pivot is hinged to the lower end face of the middle part of the seat cushion, and a Z-shaped pivot is hinged to the upper end face of the rear end of the seat cushion. After the armrest is unlocked, by pushing the armrest outward, the pivot rotates relative to the armrest and the seat cushion, changing from the retracted state to the unfolded state. The pivot is set horizontally to open the armrest. Pulling or pushing the armrest inward puts the pivot in the retracted state, thus closing the armrest. The structure is simple and easy to operate, realizing the horizontal opening or closing of the armrest.

[0010] A further feature of this invention is that the locking structure includes an unlocking switch, a first connector, and a second connector that cooperates with the first connector. The second connector is fixedly mounted on the seat cushion. The unlocking switch and the first connector are both hinged to the inside of the armrest via a hinge shaft. The unlocking switch and the first connector are connected by a connecting rope. The unlocking switch rotates around the hinge shaft to drive the first connector to connect or separate from the second connector.

[0011] With the above-mentioned further configuration, the user drives the unlocking switch to rotate relative to the hinge shaft, which in turn moves the connecting rope, causing the first connecting piece to rotate relative to the hinge shaft and separate from the second connecting piece to unlock. This makes the operation convenient, less strenuous, and easier for the elderly to use.

[0012] A further feature of this invention is that the first connector is provided with a hook, and the second connector is provided with a latch, with the hook hooked into the latch to lock the handrail.

[0013] With the above-mentioned further design, the handrail is pulled inward so that the hook is placed in the slot, realizing the locking function of the handrail. After the connector is rotated under the action of the unlocking switch, the hook is disengaged from the slot to unlock, and the handrail can be pushed outward. The structure is stable, convenient and quick.

[0014] A further feature of this invention is that a mounting base is fixedly provided on the handrail, a connecting member is hinged to the mounting base, and a reset torsion spring is provided between the connecting member and the mounting base.

[0015] With the above-mentioned further configuration, after the user releases the unlocking switch, connector one automatically resets under the action of the reset torsion spring. When the handrail is closed, connector two presses against connector one to rotate, and the hook is set in the slot to achieve locking. Attached Figure Description

[0028] like Figure 1-7 As shown, a massage chair armrest with a double-swivel side-opening structure includes a seat cushion 1, a backrest 2, and armrests 3 on both sides of the seat cushion 1. At least one armrest 3 has its rear end and middle connected to the seat cushion 1 via a swivel 4, which drives the armrest to slide relative to the seat cushion 1 to open the armrest. A locking structure 5 is provided between the front end of the armrest 3 and the seat cushion 1 to lock or unlock the armrest 3. After unlocking the armrest 3, the armrest 3 can be pushed outward to open the side of the armrest, making it convenient for the user to go up and down. The armrest can be pulled inward and locked by the locking structure 5. The sliding opening structure of the armrest makes the space occupied after the armrest is opened small, less likely to pinch the hand, and safer.

[0029] Specifically, the pivot 4 installed at the rear end of the armrest 3 is arranged in a "Z" shape, and the pivot 4 installed in the middle of the armrest 3 is arranged in a straight line. Both pivots 4 are hinged at one end to the armrest 3 and at the other end to the seat cushion 1. A fixing seat 6 is provided on the inner side of the armrest 3, and the pivots 4 are hinged to the fixing seat 6, facilitating installation and processing of the armrest 3. When the armrest 3 is opened relative to the seat cushion 1, both pivots 4 are horizontally positioned between the armrest 3 and the seat cushion 1. When the armrest 3 is closed relative to the seat cushion 1, the Z-shaped pivot 4 retracts between the armrest 3 and the seat cushion 1, and the straight pivot 4 is located below the seat cushion 1. The pivot 4 is hinged to the lower end face of the middle part of the seat cushion 1, and the Z-shaped pivot 4 is hinged to the upper end face of the rear end of the seat cushion 1. After the armrest 3 is unlocked, the pivot 4 rotates relative to the armrest 3 and the seat cushion 1 by pushing the armrest outward, changing from the retracted state to the unfolded state. The pivot 4 is set horizontally to open the armrest. Pulling or pushing the armrest 3 inward will put the pivot 4 in the retracted state. The pivot 4 in the middle is located below the seat cushion 1, and the pivot 4 at the rear end has its upper part located above the seat cushion 1 and the rest located between the seat cushion 1 and the armrest 3 to close the armrest. The structure is simple and easy to operate, realizing the horizontal opening or closing of the armrest 3.

[0030] The locking structure 5 includes an unlocking switch 51, a first connector 52, and a second connector 53 that cooperates with the first connector 52. The second connector 53 is fixedly mounted on the seat cushion 1. The unlocking switch 51 and the first connector 52 are both hinged to the inside of the armrest 3 via a hinge shaft 7. The unlocking switch 51 and the first connector 52 are connected by a connecting rope 54, which is a brake cable. One end of the connecting rope 54 is fixed to the unlocking switch 51, and the other end is hooked onto the first connector 52. The connecting rope 54 is hidden inside the armrest 3. The hinge shaft 7 of the unlocking switch 51 is vertically mounted on the armrest 3. The inner side of the handrail 3 is provided with a receiving groove 31, and the unlocking switch 51 is located in the receiving groove 31. The unlocking switch 51 rotates around the hinge shaft 7 to drive the first connector 52 to connect or separate from the second connector 53. When the user drives the unlocking switch 51 to rotate relative to the hinge shaft 7, it drives the connecting rope 54 to move, causing the first connector 52 to rotate relative to the hinge shaft 7 and separate from the second connector 53 to unlock. The operation is convenient, less strenuous, and easier for the elderly to use. The first connector 52 is provided with a hook 521, and the second connector 53 is provided with a latch 531. The hook 521 hooks into the latch 531 to achieve the connection of the handrail 3. Locking can also be achieved by having a hook 521 on the second connector 53 and a latch 531 on the first connector 52. Pulling the armrest 3 inward causes the hook 521 to engage with the latch 531, thus locking the armrest 3. When the first connector 52 rotates under the action of the unlocking switch 51, the hook 521 disengages from the latch 531, unlocking the armrest 3 and allowing it to be pushed outward. The structure is stable, convenient, and quick. A mounting base 32 is fixedly provided on the armrest 3. The first connector 52 is hinged to the mounting base 32, and the hinge shaft 7 of the first connector 52 is horizontally positioned on the mounting base 32. The first connector 52 rotates around... The hinge shaft 7 swings, and a reset torsion spring 33 is provided between the first connector 52 and the mounting base 32. The mounting base 32 and the first connector 52 are both provided with mounting shafts 34. The two ends of the reset torsion spring 33 are respectively sleeved on the corresponding mounting shafts 34. After the user releases the unlocking switch 51, the first connector 52 automatically resets under the action of the reset torsion spring 33. When the armrest part 3 is closed, the second connector 53 presses against the first connector 52 to rotate. After the hook 521 enters the slot 531, the reset torsion spring 33 resets. The hook 521 is hooked in the slot 531 to achieve locking. Unlocking is not possible without driving the unlocking switch 51.
