Multi-adaptability bicharacteristic multidirectional-rotation rocking chair

Abstract

The invention provides a multi-adaptability bicharacteristic multidirectional-rotation rocking chair which comprises a chair seat (1) and is characterized in that the bottom of the chair seat (1) is provided with a rocking disc (2); the bottom of the rocking disc (2) is an arc surface (21); the arc surface (21) is a curved surface formed through swing of an arc line (211) with the radius of R1 by using radius R2; the radius R2 and the radius R1 are greater than the distance between a gravity center G (10) and the support surface; the chair seat (1) is composed of a foot rest (3) and a seat frame (4) positioned on an upper end part, a hole group A, a hole group A1 and a hole group A2 are provided on the upper end part of the foot rest (3), a hole group B which is associated to the seat frame (4) is provided at the lower part of the seat frame (4), so that the horizontal position of the seat frame (4) on the foot rest (3) is variable, and the gravity center G (10) can be adjusted to be close to or superposed with a center line X (20) of the rocking disc (2) . The rocking chair has simple position adjusting structure for gravity center, and is suitable for using by individuals with different postures and is easy to be popularized and applied.

Description

technical field [0001] The invention relates to a rotating swing rocking chair, in particular to a multi-adaptive double-characteristic multi-directional rotating swing rocking chair. Background technique [0002] The various rotating swinging devices currently used by the public based on the principle of rotating pendulum, such as adult rocking chairs, baby cradles or cradles, children's rocking horses, etc., can only swing in a single direction forward and backward, and have only a single characteristic The swing function of the existing rotating swinging tool is insufficient or perfect in the entertainment and interest embodied in actual use. [0003] Although the "Tumbler Fitness Rocking Chair" with the application number 200720157550.X provides the public with a rocking chair technology that can rock in multiple directions, the rocking chair technology can only achieve the same or single characteristic rocking function in different directions. And this technology also ...

AI Technical Summary

Problems solved by technology

[0002]The various rotating swings and swings made by the public using the rotating swing principle, such as adult rocking chairs, baby cradles or cradles, children's rocking horses, etc. It can only swing in a single direction forward and backward, and only has a swing function with a single characteristic, so that the entertainment and interest embodied in the actual use of the existing rotating swing swing are not sufficient or perfect

[0003] Although the "Tumbler Fitness Rocking Chair" with the application number 200720157550. In different directions, only the same or single characteristic swing function can be realized, and this technology is also prone to the following defects: 1. The technical solution of the rocking chair requires a counterweight with a large quality, which makes the rocking chair relatively heavy, not only has many consumables and The production cost is high, and it is not conducive to the movement and circulation of the rocking chair product

2. In this technical solution, because "the chair is located in the tumbler shell", it is not easy for people to sit directly on the "chair", or it is not easy for people who have been sitting on the "chair" to get off the rocking chair, that is, people are in the rocking chair. Sitting up and sitting up is inconvenient, making the rocking chair only "especially suitable for use by children"

4. In order to keep the rocking chair from falling down, the rocking chair must be bulky as a whole, so that it is laborious to drive and the swing efficiency is low. It needs continuous external force support to maintain the swing, so that the swing of the rocking chair is mostly in a passive driving swing state, and the rocking chair It is difficult to obtain free reciprocating swing and lack the effect of leisure use in the free swing state, and it is difficult to meet the requirements of leisure use; and because the rocking chair is bulky as a whole, it is easy to generate a large impact on the ground or floor and easily cause vibration and noise. It is not conducive to the popularization and application of this technical solution

5. When the rocking chair is used by a larger child or an individual with a different body shape, the position of the overall center of gravity formed by the rocking chair and the human body is likely to be greatly shifted or changed, which not only easily affects the normal use of the rocking chair, but also its There are potential safety hazards in use, even if the rocking chair is provided with safety belts, this defect cannot be overcome
