Bicharacteristic multidirectional rotation swing chair

Abstract

The invention provides a bicharacteristic multidirectional rotation swing chair. The chair comprises a chair seat (1), wherein the bottom of the chair seat (1) is provided with a swing disc (2); the bottom surface of the swing disc (2) is a spherical cambered surface (21) formed by rotating an arc line (211) having a radius of R1 in terms of a radius of R2; the spherical cambered surface (21) and the swing disc (2) share a central line X; feet of a human on the chair seat (1) can touch a support plane in which the swing disc (2) is positioned; and each of the vertical and horizontal radiuses R1 and R2 of the spherical cambered surface (21) is greater than a distance between a common swing gravity center G (10) and the support plane in which the swing disc (2) is positioned. The swing chair has a novel function, has different free swing characteristics vertically and horizontally, and has the advantages of realization of the different characteristics synthesized free reciprocating swing in different vertical directions, simple structure, portable swing use, and good use comfortableness and interest.

Description

technical field [0001] The invention relates to a dual-characteristic multi-directional rotating 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 tends to have the following defects: 1. The technical solution of the ro...

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 an adult with a large mass uses the rocking chair, the overall center of gravity of the rocking chair and the human body tends to move upwards, which easily affects the normal or safe use of the rocking chair. Although the rocking chair is equipped with a safety belt, However, it is impossible to completely eliminate the potential safety hazards in its use.
