A rocking chair

Abstract

A rocking chair includes a seat, a support frame, a seat limiting mechanism, a rocking mode conversion unit, and a drive mechanism. The drive mechanism includes a drive motor power output unit and a rotating shaft. When the rotating shaft rotates, the rocking mode conversion unit locks the seat to the rotating shaft and separates the drive component from the drive engagement / disengagement component, thus achieving one rocking mode. When the rotating shaft rotates again, the rocking mode conversion unit unlocks the seat to the rotating shaft and engages the drive component with the drive engagement / disengagement component, thus achieving another rocking mode. The rocking mode conversion unit enables the switching between the two rocking modes. This rocking chair is simple in structure and low in cost, allowing for the interchange of at least two rocking modes.

Description

Technical Field

[0001] This invention relates to a rocking chair. Background Technology

[0002] With the improvement of people's living standards, there is a growing demand for rocking chairs, especially for families with infants and toddlers. Parents who can care for their children while also having time to work or do housework have a strong need for a rocking chair that allows their children to sway. While some rocking chairs on the market have a fixed seat and rotating shafts, offering only a single swaying method, others use a Z-shaped design with two rotating shafts connected to the seat, also offering only a single swaying method. It's difficult to find a rocking chair that truly meets the market's need for two interchangeable swaying modes. Summary of the Invention

[0003] The present invention is proposed in view of the above-mentioned problems existing in the prior art. The purpose of the present invention is to provide a rocking chair with two swing modes that can be switched between each other, and which has a simple structure and low cost.

The drive mechanism includes a drive motor power output unit and a rotating shaft. One end of the rotating shaft is fixedly connected to the drive motor power output unit, and the other end of the rotating shaft is pivotally connected to the seat. Both the rotating shaft and the drive motor power output unit are mounted on the support frame. The seat limiting mechanism includes a drive member and a drive engagement / disengagement member. When the rotating shaft rotates, the seat limiting mechanism limits the seat to maintain a set angle with the rotating shaft.

[0033] Now refer to the appendix Figures 1-17 Embodiments of the present invention are described.

[0034] A rocking chair includes a seat body 1, a support frame 2, a seat limiting mechanism 3, a swing mode conversion unit 4, and a drive mechanism 5. The drive mechanism 5 includes a drive motor power output unit 6 and a rotating shaft 7. One end of the rotating shaft 7 is fixedly connected to the drive motor power output unit 6, and the other end of the rotating shaft 7 is pivotally connected to the seat body 1. Both the rotating shaft 7 and the drive motor power output unit 6 are mounted on the support frame 2. The seat limiting mechanism 3 includes a drive member 9 and a drive engagement / disengagement member 10. When the rotating shaft 7 rotates, the seat limiting mechanism 3 limits the seat body 1 to maintain a set angle with the rotating shaft 7. The swing mode conversion unit 4 includes a seat locking / unlocking part 11 and a seat limiting mechanism locking / unlocking part 12. The seat locking / unlocking part 11 is used to lock or unlock the seat body 1 and the rotating shaft 7, and the seat limiting mechanism locking / unlocking part 12 is used to engage or disengage the drive engagement / disengagement member 10 relative to the drive member 9. When the rotating shaft 7 rotates, the swing mode conversion unit 4 locks the seat 1 to the rotating shaft 7 and separates the driving member 9 from the driving engagement separation member 10, which is one swing mode. When the rotating shaft 7 rotates, the swing mode conversion unit 4 unlocks the seat 1 from the rotating shaft 7 and engages the driving member 9 with the driving engagement separation member 10, which is another swing mode. The swing mode conversion unit 4 provides a rocking chair with two swing modes and allows the two swing modes to be switched between each other. This invention provides a rocking chair with two swing modes, thereby overcoming the disadvantages of a single swing mode, providing consumers with better entertainment and choice. Furthermore, the ability to switch between the two swing modes overcomes the disadvantage of requiring more raw materials and resulting in higher costs when the two modes cannot be switched, thus achieving low cost and simple structure.

[0035] The seat locking and unlocking part 11 includes a seat locking and unlocking component 13 and a seat locking and unlocking switch 15. The seat limiting mechanism locking and unlocking part 12 includes a limiting mechanism engagement separation component 14 and a limiting mechanism engagement separation switch 25. The seat locking and unlocking switch 15 includes a locking position 16 and an unlocking position 17. When the seat locking and unlocking switch 15 is in the locking position 16, the seat locking and unlocking component 13 locks the seat 1 to the rotating shaft 7, and the limiting mechanism engagement separation switch 25 is in the separation lock position 18. The limiting mechanism engagement separation component 14 separates the driving component 9 from the driving engagement separation component 10. At this time, the seat 1 rotates with the rotating shaft 7 and the driving engagement is activated. The separating member 10 rotates with the seat body 1 and the rotating shaft 7, and the seat body 1 will not be unable to rotate with the rotating shaft 7 due to the engagement of the driving engagement separating member. This is one swing mode. When the seat body locking and unlocking switch 15 is in the unlocking lock position 17, the seat body locking and unlocking member 13 separates the seat body 1 from the rotating shaft 7, and the limiting mechanism engagement separating switch 25 is in the engagement lock position 19. The limiting mechanism engagement separating member 14 makes the driving member 9 engage with the driving engagement separating member 10. At this time, the seat body 1 rotates relative to the rotating shaft 7. The driving member 9 and the driving engagement separating member 10 engage to limit the angle maintained between the seat body 1 and the rotating shaft 7. This is another swing mode. When the seat lock / unlock switch 15 is in the locked position 16, the limiting mechanism and the release switch 25 must be in the release position 18 to form the swing mode. When the seat lock / unlock switch 15 is in the unlocked position 17, the limiting mechanism and the release switch 25 must be in the release position 19. When the seat lock / unlock switch 15 changes from the locked position 16 to the unlocked position 17, the limiting mechanism and the release switch 25 changes from the release position 18 to the release position 19, thus changing from one swing mode to another swing mode.

[0036] The seat locking / unlocking component 13 has a slot 20 that mates with the rotating shaft 7. The seat locking pin 23 of the seat locking / unlocking switch 15 moves out of the unlocking lock position hole 30, and the seat locking / unlocking component 13 moves downward relative to the seat 1. The slot 20 of the seat locking / unlocking component 13 engages with the rotating shaft 7. Under the action of the return spring 21, the seat locking pin 23 extends into the locking lock position hole 31. At this time, the seat locking / unlocking switch 15 changes from the unlocking lock position 17 to the locking lock position 16. The seat 1 is then locked to the rotating shaft 7, and the mechanism engagement separation switch 22 is limited. When the locking pin 23 of the fixed mechanism separating part 14 moves out of the locking position 19 hole, the locking pin 23 of the fixed mechanism separating part 14 moves downward and, under the action of the return spring 21, goes deeper into the separating locking position hole 32. At this time, the seat limiting separation switch 22 changes from the locking position 19 to the separating locking position 18. At this time, the driving part 9 separates from the driving part 10, thereby achieving the conversion from one swing mode to another swing mode. Conversely, it is the conversion from one swing mode to another swing mode. The two swing modes can be converted to each other.

[0037] In another preferred embodiment, the seat locking / unlocking component 13 has a slot 20 that mates with the rotating shaft 7. The seat locking pin 23 of the seat locking / unlocking switch 15 moves out of the unlocking lock hole 30, and the seat locking / unlocking component 13 moves downward relative to the seat 1. The slot 20 of the seat locking / unlocking component 13 engages with the rotating shaft 7. Under the action of the return spring 21, the seat locking pin 23 extends into the hole of the locking position 16. At this time, the seat locking / unlocking switch 15 switches from the unlocking lock position 17 to the locking lock position 16. The seat 1 is then locked to the rotating shaft 7, and the mechanism's engagement separation component is restricted. When the locking pin 23 of the limiting mechanism 14 of the limiting mechanism 22 moves out of the locking hole 33, the locking pin 23 of the limiting mechanism 14 moves upward and, under the action of the return spring 21, moves into the locking hole 32. At this time, the limiting mechanism separation switch 22 changes from the locking position 19 to the locking position 18. At this time, the driving member 9 separates from the driving engagement member 10, thereby achieving the conversion from one swing mode to another swing mode. Conversely, it is the conversion from one swing mode to another swing mode. The two swing modes can be converted to each other.

[0038] The seat locking and unlocking component 13 is provided with a slot 20 that mates with the rotating shaft 7. The seat locking and unlocking component 13 is arranged to move up and down relative to the seat 1. The seat locking and unlocking switch 15 includes a return spring 21, a locking pin 23, and a locking hole on the seat 1 that mates with the locking pin 23. The limiting mechanism engagement separation switch 25 includes a return spring 21, a locking pin 23, and a locking hole on the drive engagement separation component 10 that mates with the locking pin 23. The limiting mechanism engagement separation component 14 is arranged to move up and down relative to the drive engagement separation component 10. When the seat locking / unlocking component 13 moves downward relative to the seat 1 and the slot 20 engages with the rotating shaft 7, the locking pin 23 of the seat locking / unlocking switch 15 engages with the locking hole on the seat 1 that mates with the locking pin 23 under the action of the return spring 21. At this time, the seat locking / unlocking switch 15 is in the locked position 16, and the seat 1 is locked to the rotating shaft 7. The limiting mechanism engagement separation component 14 moves downward relative to the driving engagement separation component 10. Under the action of the return spring 21, the locking pin 23 of the limiting mechanism engagement separation switch 25 penetrates into the locking hole on the driving engagement separation component 10 that mates with the locking pin 23. At this time, the limiting mechanism engagement separation switch 25 is in the unlocked position 17, and the driving component 9 separates from the driving engagement separation component 10. This is a swinging motion. In the first mode, when the seat locking / unlocking component 13 moves upward relative to the seat 1 and unlocks the rotating shaft 7, the locking pin 23 of the seat locking / unlocking switch 15 engages with the locking hole on the seat 1 that matches the locking pin 23 under the action of the return spring 21. At this time, it is in the unlocked lock position 17, and the rotating shaft 7 is unlocked from the seat 1. The limiting mechanism engagement separation component 14 moves upward relative to the driving engagement separation component 10, and the locking pin 23 of the limiting mechanism engagement separation switch 25, under the action of the return spring 21, penetrates into the locking hole on the driving engagement separation component 10 that matches the locking pin 23. At this time, the limiting mechanism engagement separation switch 25 is in the unlocked lock position 17, and the driving component 9 engages with the driving engagement separation component 10. This is another swing mode, realizing the conversion between the two swing modes.

[0039] The limiting mechanism separating part 14 is provided with a slot 20 that mates with the drive part 9. When the seat 1 is unlocked from the rotating shaft 7, the limiting mechanism separating part 14 and the drive separating part 10 are pivotally engaged. Alternatively, when the drive part 9 is provided with a slot 20, the limiting mechanism separating part 14 is provided with a locking pin 23.

[0040] The seat limiting mechanism 3 includes a movable part and a movable groove that cooperates with the movable part. When the rotating shaft 7 rotates, the movable part moves relative to the movable groove. The driving part 9 is the movable part, and the driving cooperation separation part 10 is the movable groove. The cooperation structure between the movable groove and the movable part is simple and low in cost.

[0041] A rotating component 24 is provided on the moving component, and the rotating component 24 can rotate around the moving component. The rotating component 24 mates with the surface of the moving groove. The rotating component 24 reduces friction when the moving component moves with the moving groove. In this embodiment, the rotating component 24 is a bearing.

[0042] The movable component is mounted on the base 1, and the movable slot is mounted on the support frame 2, or the movable component is mounted on the support frame 2, and the movable slot is mounted on the base 1.

[0043] The drive mechanism 5 also includes a sensor mounted on the drive motor 26, and a reduction gear set 27 connected to the drive motor 26. The sensor controls the drive motor 26 to continuously reciprocate in both directions, thereby causing the rotating shaft 7 to continuously reciprocate in both directions. By detecting the rotation angle of the rotating shaft 7 and the forward and reverse rotation of the drive motor 26, the movement distance of the base 1 is controlled. The reduction gear set 27 reduces speed and increases force, resulting in a simple structure and low cost. The tilted setting of the rotating shaft 7 can generate a conversion between kinetic and potential energy, thereby achieving labor saving.

[0044] A rocking chair includes a drive mounting box 29. A movable component includes an upper end and a lower end, which are fixedly connected or integrally formed. The upper end passes through the drive mounting box 29 and connects to the seat body 1. The lower end mates with a movable slot. The connection point between the upper end and the seat body 1 is offset from the mating point between the lower end and the movable slot. The upper end of the movable component and the slot 20 passing through the drive mounting box 29 are located in the middle of the drive mounting box 29, reducing the cost of covering the slot 20 and decreasing the overall size. The misalignment of the mating point from the connection point generates torque, making the rocking motion less smooth.

[0045] This invention provides a rocking chair with two interchangeable swing modes, which greatly increases the enjoyment of consumers. It has a simple structure and low cost. It was invented after long-term and careful research by engineers. It is not something that people in the field would easily think of and is not common knowledge.
