Description

Technical Field

[0001] This invention belongs to the field of office chair technology, specifically an office chair that facilitates rest and its usage. Background Technology

[0002] An office chair designed for rest is a piece of furniture that provides support and comfort to people while they work or rest. It reduces the stress on the body from prolonged sitting. The design usually takes ergonomics into account, providing good support and comfort to reduce the stress on the body from prolonged sitting. It can be used with computer screens and keyboards to help maintain the correct posture, which helps protect health. It is also durable and can maintain good performance for a long time.

[0003] A Chinese patent with publication number CN105747642A discloses an office chair with a mouse console, mainly comprising a seat and a backrest. The right armrest is mounted on the right side of the seat via two right support rods, and the left armrest is mounted on the left side of the seat via one or two support rods. A mouse pocket with an upward-facing opening is provided on the outside of the support rod of the left armrest. A top plate that can be moved to the left side of the right armrest is provided above the right armrest, and a mouse console that can be moved to the top of the right armrest is provided on the outside of the right armrest. When the mouse needs to be operated, the top plate is moved to the left side of the right armrest, the mouse console is moved from the right side of the right armrest to the top of the right armrest, the right armrest is then lifted upward, and the right armrest is pushed forward to move it into place. After it moves forward, the right armrest is pressed downward so that the fixing shaft at the top of the right support rod enters the positioning groove located at the rear of the receiving groove for positioning. At this time, pushing the mouse console forward or backward will not cause the mouse console to move.

[0004] The aforementioned office chairs with built-in mouse consoles primarily aim to alleviate shoulder muscle tension during mouse operation, but they do not consider improving user comfort by adjusting the chair angle. When users adjust the chair angle for a rest during lunch break, good neck support can significantly reduce neck muscle tension and pain. Maintaining an incorrect posture for extended periods during rest often leads to overuse of neck muscles, resulting in soreness and stiffness. During sleep, proper support allows the neck to relax, thereby reducing muscle burden.

[0018] A method for using an office chair that facilitates rest includes:

[0019] S1. When resting in an office chair that is easy to use, after the user sits on the seat cushion, moving the sliding plate upward will cause the first sliding block to move through the cooperation of the first steel wire rope and the limit bracket. Then, through the long plate, the locking block will separate from the limit gear plate, and the rotating shaft will no longer be limited. Pushing the backrest will adjust the angle of the backrest through the cooperation of the connecting plate, connecting groove and rotating shaft.

[0020] S2. When the backrest tilts, the connecting block will pull the No. 2 steel wire rope to slide inside the slide. When the No. 2 steel wire rope moves, the guide frame will pull one end of the tray to tilt. When the tray moves, the cooperation between the support ring and the rotating shaft will make the tray move in an arc around the shaft. After the backrest angle is adjusted to the predetermined angle, the tray and the seat cushion will be in a parallel state, which will facilitate the support of the user's legs when the user is resting.

[0021] S3. When adjusting the backrest tilt angle, the rotating shaft will rotate, which will drive the stop block to move synchronously. When the stop block contacts the outer wall of the limiting block, it will limit the rotating shaft, and then limit the position of the backrest tilt angle. After the backrest tilt angle is adjusted to the predetermined position, the sliding plate will no longer be limited. The return spring pulls the sliding plate to reset, and then the bottom of the first sliding block will no longer be limited. The first spring resets and pushes the connecting rod to slide inside the cylinder, which will push the locking block to reset and contact the outer wall of the limiting gear plate, thereby fixing the position of the rotating shaft and fixing the tilt angle of the backrest adjustment, so that the user can lean against the backrest to rest.

[0022] S4. When the backrest is tilted, the length of the traction rope remains unchanged due to the arc-shaped movement. The slide will pull the drive block to move. When the drive block moves, it will drive the slip ring to move on the guide plate, thus making the drive block move smoothly. When the drive block moves, the mounting bracket and drive plate will push the second sliding block to slide inside the sliding groove. After the tilt angle of the backrest is adjusted to the movement angle, the second sliding block will push the arc plate to the outside. When the user rests, the arc plate will support the user's neck, making it easier for the user to rest.

[0023] S5. The drive motor is controlled by the control switch. The drive motor drives the crankshaft to rotate. The bearing facilitates the smooth rotation of the crankshaft. When the crankshaft rotates, the support block moves repeatedly through the drive rod. When the support block moves, the massage head moves through the rubber plate to massage the user's neck and improve sleep quality.

[0024] The beneficial effects of this invention are as follows:

[0025] 1. The present invention provides an office chair that facilitates rest. After the angle of the chair is adjusted using an arc-shaped plate, it supports the user's neck when resting. When the backrest is tilted, a traction rope pulls a drive block, which in turn moves a sliding ring on a guide plate, allowing the drive block to move smoothly. As the drive block moves, the mounting bracket and drive plate push a second sliding block to slide within a sliding groove. After adjusting the backrest's tilt angle to the desired position, the second sliding block pushes the arc-shaped plate outwards. Thus, when the user rests, the arc-shaped plate supports the user's neck, facilitating rest, reducing neck discomfort, protecting the cervical spine, and preventing deformation.

[0026] 2. The office chair for easy rest described in this invention provides leg support for the user when resting. When the backrest tilts, a connecting block pulls a second steel wire rope to slide inside a groove. As the second steel wire rope moves, a guide frame pulls one end of the support plate to tilt. When the support plate moves, the cooperation between the support ring and the rotating shaft causes the support plate to make an arc-shaped movement around the shaft. After adjusting the backrest angle to a predetermined angle, the support plate and the seat cushion will be parallel. This provides leg support for the user when resting, relieving fatigue, improving posture, preventing varicose veins, and increasing comfort.

[0027] 3. The office chair described in this invention is designed for comfortable rest. Its massage head allows for easy massage of the user's neck, improving rest quality. When the drive motor operates, it rotates the crankshaft. The crankshaft rotates smoothly through the bearings. The crankshaft's rotation, via the drive rod, causes the support block to move repeatedly. This movement of the support block, through the rubber plate, causes the massage head to move, massaging the user's neck. This relieves muscle tension and pain, promotes blood circulation in the muscles, relaxes tense muscles, and helps improve sleep quality. Attached Figure Description

[0042] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0043] like Figure 1 - Figure 10As shown in the embodiment of the present invention, an office chair for easy rest includes a frame 1, a support plate 2 fixedly installed on the frame 1, a seat cushion 3 on the top of the support plate 2, a backrest 4 on the top of the support plate 2, a strip groove 11 inside the support plate 2, an adjustment component inside the strip groove 11 connected to the backrest 4, a limit block 27 fixedly installed inside the strip groove 11, a reset component inside the limit block 27, a traction rope 34 fixedly connected to the top of the limit block 27, a slide rail 35 corresponding to the traction rope 34 inside the backrest 4, a storage box 36 fixedly installed inside the backrest 4, a drive component inside the storage box 36, a sliding groove 37 on the storage box 36, a second sliding block 38 inside the sliding groove 37 connected to the drive component, and an arc on the second sliding block 38. The curved plate 39 is used to support the user's neck. The bottom of the support plate 2 is equipped with a support component. When the user is working in the office chair, the seat cushion 3 supports the user, making it convenient for the user to work. When the user needs to rest, the adjustment component adjusts the position of the backrest 4. When adjusting the position of the backrest 4, the traction rope 34 and the drive component will push the second sliding block 38 to slide inside the sliding groove 37. After adjusting the tilt angle of the backrest 4 to the movement angle, the second sliding block 38 will push the curved plate 39 to the outside, so that the curved plate 39 supports the user's neck when the user rests. At the same time, the support component can also support the user's legs, making it convenient for the user to rest. The reset component can make the backrest 4 return to its original position. The strip groove 11 provides installation space for the adjustment component.

[0044] like Figure 1 , Figure 4 , Figure 6 and Figure 8As shown, a headrest 5 is fixedly installed on the top of the backrest 4. Two sets of concave frames 6 are fixedly installed on the frame 1. Two sets of guide rods 7 are fixedly installed inside the concave frames 6. A sliding plate 8 is set inside the concave frames 6, and the guide rods 7 pass through the sliding plate 8. A steel wire rope 10 is fixedly connected to the bottom of the sliding plate 8. The adjustment assembly includes a limiting ring 12, a rotating shaft 13, a limiting gear 14, a connecting plate 15, and a connecting groove 16. The limiting ring 12 is fixedly installed inside the strip groove 11. The rotating shaft 13 passes through the inside of the limiting ring 12. The limiting gear 14 is fixedly installed at both ends of the rotating shaft 13. Three sets of connecting plates 15 are fixedly installed on the outer wall of the rotating shaft 13. The connecting groove 16 is set inside the backrest 4, and the connecting plate 15 extends into the inside of the connecting groove 16. A return spring 9 is slidably mounted on the rod 7, and the top of the return spring 9 is fixedly connected to the bottom of the sliding plate 8. The headrest 5 supports the user's head. When the sliding plate 8 is moved upward, the guide rod 7 guides the sliding plate 8. The first steel wire rope 10 and the limit frame 19 work together to drive the first sliding block 23 to move. Then, the long plate 24 drives the locking block 25 to separate from the limit gear plate 14, and the rotating shaft 13 is no longer limited. Pushing the backrest 4 will adjust the angle of the backrest 4 through the cooperation of the connecting plate 15, the connecting groove 16 and the rotating shaft 13. When no more pressure is applied to the sliding plate 8, the return spring 9 will push the sliding plate 8 to reset. The connecting plate 15 and the connecting groove 16 are fixedly connected by bolts, thereby fixing the position of the backrest 4.

[0045] like Figure 3 , Figure 4 and Figure 5As shown, the inside of the strip groove 11 is provided with a positioner 17 corresponding to the limiting gear plate 14. A first hole 18 is provided on the front of the positioner 17. A limiting frame 19 is fixedly installed inside the positioner 17, and a first steel wire rope 10 extends through the first hole 18 into the inside of the limiting frame 19. A cylinder 20 is fixedly installed inside the positioner 17, and a first spring 21 is provided inside the cylinder 20. A connecting rod 22 is fixedly connected to the top of the first spring 21, and a first sliding block 23 is fixedly connected to the top of the connecting rod 22. A long plate 24 is fixedly connected to the top of the first sliding block 23, and a locking block 25 is fixedly connected to the top of the long plate 24. The locking block 25 matches the dimensions of the outer wall of the limiting gear plate 14. The bottom of the rotating shaft 13 is... The secondary connection has a stop block 26, and the first hole 18 facilitates the sliding position of the first wire rope 10. The limit frame 19 moves the position of the first wire rope 10. When the first wire rope 10 moves, the limit frame 19 changes the direction of movement of the first wire rope 10, which in turn pulls the first sliding block 23 to move downward. When the first wire rope 10 no longer applies pressure to the bottom of the first sliding block 23, the first spring 21 resets and pushes the connecting rod 22 to slide inside the cylinder 20, which in turn pushes the locking block 25 to reset and contact the outer wall of the limit gear plate 14, fixing the position of the rotating shaft 13. This can fix the tilt angle of the backrest 4. The positioner 17 is provided with a groove to limit the long plate 24, which facilitates the up and down movement of the long plate 24.

[0046] like Figure 2 and Figure 3 As shown, a guide frame 49 is fixedly installed at the bottom of the support plate 2. The support assembly includes a support ring 28, a rotating shaft 29, and a support plate 30. The support ring 28 is fixedly installed at the bottom of the support plate 2. The rotating shaft 29 passes through the inside of the support ring 28. The support plate 30 is fixedly connected to the rotating shaft 29. Two sets of No. 2 steel wire ropes 31 are fixedly connected to the support plate 30. The inside of the frame 1 is provided with a groove 32 corresponding to the No. 2 steel wire ropes 31. The No. 2 steel wire ropes 31 pass through the groove 32 and the inside of the guide frame 49. A connecting block 33 is fixedly installed on the backrest 4. The connecting block 33 is fixedly connected to one end of the No. 2 steel wire rope 31. The guide frame 49 limits the movement of the No. 2 steel wire rope 31. When the second steel wire rope 31 moves, it facilitates the movement of the support plate 30. When the backrest 4 tilts, the connecting block 33 pulls the second steel wire rope 31 to slide inside the slide groove 32. When the second steel wire rope 31 moves, the guide frame 49 pulls one end of the support plate 30 to tilt. When the support plate 30 moves, the cooperation between the support ring 28 and the rotating shaft 29 makes the support plate 30 move in an arc around the axis. After adjusting the angle of the backrest 4 to the predetermined angle, the support plate 30 and the seat cushion 3 will be in a parallel state. When the user uses the office chair to rest, it supports the user's legs, expands the support area, and improves the user's rest quality.

[0047] like Figure 9 and Figure 10 As shown, the drive assembly includes a guide plate 40, a slip ring 41, a drive block 42, a mounting bracket 43, and a drive plate 44.

The drive plate 44 is movably connected to the mounting bracket 43, and the other end of the drive plate 44 is movably connected to the outer wall of the second sliding block 38. The storage box 36 has symmetrically arranged guide grooves 45. A first guide rod 46 is arranged inside the guide groove 45. A guide block 47 is arranged inside the guide groove 45, and the first guide rod 46 passes through the interior of the guide block 47. A second spring 48 is arranged around the first guide rod 46, and one end of the second spring 48 is fixedly connected to the outer wall of the guide block 47. The guide block 47 is fixedly connected to the outer wall of the slip ring 41. The traction rope 34 passes through the slip ring 41. The guide 35 pulls the drive block 42 to move. When the drive block 42 moves, it will drive the slip ring 41 to move on the guide plate 40, thereby making the drive block 42 move smoothly. When the drive block 42 moves, the mounting bracket 43 and the drive plate 44 will push the second sliding block 38 to slide inside the sliding groove 37. After the tilt angle of the backrest 4 is adjusted to the angle of movement, the second sliding block 38 will push the arc plate 39 to the outside. When the user rests, the arc plate 39 will support the user's neck, making it easier for the user to rest. After the backrest 4 is reset, when the traction rope 34 no longer applies pressure to the drive block 42, the second spring 48 resets and pushes the guide block 47 to move smoothly on the first guide rod 46. When the guide block 47 moves, the slip ring 41 will drive the drive block 42 to reset, thereby pulling the second sliding block 38 to reset and moving the arc plate 39 into the sliding groove 37 for storage.

The second guide rod 52 is fixedly installed on the square block 51. The slider 53 is located inside the square groove 50, and the second guide rod 52 passes through the interior of the slider 53. One end of the third steel wire rope 54 is fixedly connected to the outer wall of the slider 53, and the other end of the third steel wire rope 54 is fixedly connected to the outer wall of the connecting plate 15. The second hole 55 is located in the square groove 50. The third spring 56 is fixedly installed on the square block 51, and the other end of the third spring 56 is fixedly connected to the slider 53. The third steel wire rope 54 passes through the square block 51 and the second hole 56. Inside hole 55, when the connecting plate 15 moves to adjust the tilt angle of the backrest 4, the third steel wire rope 54 pulls the slider 53 to move on the second guide rod 52. When the slider 53 moves, it is squeezed by the third spring 56. When the positioner 17 no longer limits the limit tooth plate 14, it also stops applying pressure to the backrest 4. The reset of the third spring 56 pushes the slider 53 to reset. The second guide rod 52 guides the slider 53. When the slider 53 resets, the third steel wire rope 54 pulls the connecting plate 15 to reset, which in turn drives the backrest 4 to reset its position. A retaining plate is set on the frame 1 to limit the position of the backrest 4, so that the backrest 4 moves precisely to its original position. The positioner 17 can fix the position of the backrest 4 after reset. Hole 55 facilitates the movement of the third steel wire rope 54.

Several massage heads 62 are sequentially arranged on the top of the rubber plate 61. Limiters are sequentially arranged at the bottom of the support block 60. A connecting shaft 64 is sequentially arranged at the bottom of the groove 63 and the support block 60. A drive rod 65 is movably connected to the connecting shaft 64. A limiting plate 66 corresponding to the limiting groove 63 is fixedly installed inside the movable groove 59, and the limiting plate 66 passes through the limiting groove 63. A bearing 67 is arranged inside the limiting plate 66, and a crankshaft 68 is installed inside the bearing 67. The drive rod 65 is movably connected to the crankshaft 68. A drive motor 69 is fixedly installed inside the movable groove 59, and one end of the crankshaft 68 is connected to the drive motor 69. The output end is fixedly connected, and the control switch 58 is electrically connected to the drive motor 69. When using an office chair for information work, the curved plate 39 contacts the user's neck, and the current inside the battery assembly 57 flows into the control switch 58. The control switch 58 is a mechanical switch, which mainly controls the opening and closing of the circuit by triggering the mechanical components, thereby controlling the operation of the drive motor 69. When the drive motor 69 is working, it drives the crankshaft 68 to rotate. When the crankshaft 68 rotates, it rotates smoothly through the cooperation of the bearing 67. When the crankshaft 68 rotates, it drives the support block 60 to move repeatedly through the drive rod 65. When the support block 60 moves, it drives the massage head 62 to move through the rubber plate 61, which massages the user's neck, relieves muscle tension and pain, promotes blood circulation in the muscles, relaxes tense muscles, and helps improve sleep quality. When the support block 60 moves, the cooperation between the limit groove 63 and the limit plate 66 makes the support block 60 move smoothly.

[0050] A method for using an office chair that facilitates rest includes:

[0051] S1. When resting in an office chair, the user sits on the seat cushion 3 and moves the sliding plate 8 upward. Through the cooperation of the first steel wire rope 10 and the limiting frame 19, the first sliding block 23 moves. Then, through the long plate 24, the locking block 25 separates from the limiting gear plate 14, and the rotating shaft 13 is no longer limited. Pushing the backrest 4 will adjust the angle of the backrest 4 through the cooperation of the connecting plate 15, the connecting groove 16 and the rotating shaft 13.

[0052] S2. When the backrest 4 tilts and moves, the connecting block 33 will pull the second steel wire rope 31 to slide inside the slide groove 32. When the second steel wire rope 31 moves, the guide frame 49 will pull one end of the support plate 30 to tilt and move. When the support plate 30 moves, the cooperation between the support ring 28 and the rotating shaft 29 will make the support plate 30 move in an arc around the shaft. After the angle of the backrest 4 is adjusted to the predetermined angle, the support plate 30 will be parallel to the seat cushion 3, which will facilitate the support of the user's legs when the user is resting.

[0053] S3. When the backrest 4 is tilted, the rotating shaft 13 rotates, which in turn drives the stop block 26 to move synchronously. When the stop block 26 contacts the outer wall of the limiting block 27, it limits the rotating shaft 13, thereby limiting the position of the backrest 4 when the tilt angle is adjusted. After the tilt angle of the backrest 4 is adjusted to the predetermined position, the sliding plate 8 is no longer limited. The reset spring 9 pulls the sliding plate 8 to reset, thereby no longer limiting the bottom of the first sliding block 23. The first spring 21 resets and pushes the connecting rod 22 to slide inside the cylinder 20, which in turn pushes the locking block 25 to reset and contact the outer wall of the limiting gear plate 14, thereby fixing the position of the rotating shaft 13 and fixing the tilt angle of the backrest 4, so that the user can lean on the backrest 4 to rest.

[0054] S4. When the backrest 4 is tilted, the length of the traction rope 34 remains unchanged due to the arc-shaped movement. The drive block 42 will be pulled to move through the slide rail 35. When the drive block 42 moves, it will drive the slip ring 41 to move on the guide plate 40, thereby making the drive block 42 move smoothly. When the drive block 42 moves, the second sliding block 38 will be pushed to slide inside the sliding groove 37 through the mounting bracket 43 and the drive plate 44. After the tilt angle of the backrest 4 is adjusted to the angle of movement, the arc plate 39 will be pushed out to the outside through the second sliding block 38. Thus, when the user is resting, the arc plate 39 will support the user's neck, making it easier for the user to rest.

[0055] S5. The drive motor 69 is controlled by the control switch 58. The drive motor 69 drives the crankshaft 68 to rotate. The bearing 67 facilitates the smooth rotation of the crankshaft 68. When the crankshaft 68 rotates, the support block 60 is driven to move repeatedly through the drive rod 65. When the support block 60 moves, the massage head 62 is driven to move through the rubber plate 61 to massage the user's neck and improve sleep quality.

[0056] Working principle: When the user sits on the seat cushion 3, the upward movement of the sliding plate 8, through the cooperation of the first steel wire rope 10 and the limiting frame 19, will drive the first sliding block 23 to move. This, in turn, will cause the locking block 25 to separate from the limiting gear plate 14 via the long plate 24, thus removing the limiting effect on the rotating shaft 13. Pushing the backrest 4, through the cooperation of the connecting plate 15, connecting groove 16, and rotating shaft 13, will adjust the angle of the backrest 4. When the backrest 4 tilts, the connecting block 33 will pull the second steel wire rope 31 to slide inside the sliding groove 32. As the second steel wire rope 31 moves, the guide frame 49 will pull one end of the support plate 30 to tilt. When the support plate 30 moves, it supports... The cooperation between the support ring 28 and the rotating shaft 29 causes the support plate 30 to move in an arc around the axis. After adjusting the angle of the backrest 4 to the predetermined angle, the support plate 30 and the seat cushion 3 will be in a parallel state, which facilitates support for the user's legs when resting. When the tilt angle of the backrest 4 is adjusted, the rotating shaft 13 will rotate, which will drive the stop block 26 to move synchronously. When the stop block 26 contacts the outer wall of the limiting block 27, it will limit the rotating shaft 13, and thus limit the position of the backrest 4 when adjusting the tilt angle. After the tilt angle of the backrest 4 is adjusted to the predetermined position, the sliding plate 8 is no longer limited, the return spring 9 pulls the sliding plate 8 to return to its original position, and thus the bottom of the first sliding block 23 is no longer limited. Spring 21 resets and pushes connecting rod 22 to slide inside cylinder 20, which in turn pushes block 25 to reset and contact the outer wall of limiting gear 14, thereby fixing the position of rotating shaft 13 and fixing the tilt angle of backrest 4, making it convenient for the user to lean against backrest 4 for rest. When backrest 4 is tilted, due to the arc motion, the length of traction rope 34 remains unchanged, and it will pull drive block 42 to move through slide rail 35. When drive block 42 moves, it will drive slip ring 41 to move on guide plate 40, thereby making drive block 42 move smoothly. When drive block 42 moves, it will push second sliding block 38 to slide inside sliding groove 37 through mounting bracket 43 and drive plate 44, thus tilting backrest 4. After the tilt angle is adjusted to the desired angle, the second sliding block 38 will push the arc plate 39 outwards. When the user is resting, the arc plate 39 will support the user's neck, facilitating rest. The control switch 58 controls the drive motor 69 to work, which will drive the crankshaft 68 to rotate. The bearing 67 facilitates the smooth rotation of the crankshaft 68. When the crankshaft 68 rotates, the drive rod 65 will drive the support block 60 to move repeatedly. When the support block 60 moves, the rubber plate 61 will drive the massage head 62 to move, massaging the user's neck. This can relieve muscle tension, reduce pain, promote blood circulation in the muscles, relax tense muscles, and help improve sleep quality.
