The present invention is a kind of multifunctional chair, which is a chair that can be used for various purposes such as expressing affection between men and women, especially having a universal rocking function and a massage function with high stability.

Although there are many types of traditional chairs, the basic structure of the chair is not limited to the combination of chair cushions, backrests, and chair legrests. Do. For example;

The chair back of the office chair tilts at an angle to allow the user to unfold comfortably, and the cushion can be rotated flat or the height of the cushion can be adjusted by adjusting hydraulic pressure or screws.

The rocking chair is rocked back and forth using the arched base.

The massage chair has a roller in the backrest that slides the roller and uses a moving effect to massage the user's back. The chair back can also be tilted to be near horizontal, allowing the user to comfortably massage at an almost lying angle.

The swivel bench is a steel frame that combines canvas with a steel frame that can be folded to make it convenient to carry or store.

The various chairs described above are all made of steel for supporting the cushion. Wood, steel pipes, rattan trunks, and plastic materials are relatively limited in their comfort and function when sitting, due to the limitations of the structural design due to the physical properties of the material itself. For example, when the user sits and receives a massage, the user only needs to feel the mechanical movement of the rollers, and the user cannot move or shake to comfortably posture. Even sitting in a rocking chair, you can only feel the change in a single motion swinging back and forth. All these shortcomings are limitations that cannot be solved by the rigid material and structure of the chair.

In other words, if you want the strength to support your back on a regular spring bed mattress, you need to place more independent and dense springs. But you can't expect a great effect on elasticity as a love mat, but especially for fat people or people who are uncomfortable, it doesn't really help, and you need to move the love mat to change your posture. Not ideal and inconvenient to do.

The main purpose of this development is to provide a multifunctional chair. The universal base is installed under the seat cushion, which includes a top plate connected to the cushion and a bottom plate connected to the base support of the chair, and at least four circular springs are installed between the top plate and the bottom plate. ; By utilizing the high elasticity of the circular spring, the automatic recovery that can be easily stretched and deformed, the rigid base support of the traditional chair can be changed to the flexible support, and the chair can be made with all-around shaking function.

As mentioned above, this circular spring is made of high carbon steel material, has a suitable size to fit the height of the chair, and has sufficient strength to support the weight of the chair and the deformation force generated when the user performs various movements in the chair. have. In addition, the number of circular springs is at least four, which has a relatively good stability, highlighting the ideas of the chair developer.

Another purpose of this development is to install a vibration motor directly under the cushion, which not only enhances the effect of the massage but also strengthens the user's blood circulation, making the whole body cool and making it easier to fall asleep. Can give

The purpose of the expansion of this development can be said to be a separately installed object support. At the bottom of the base, each of the armrests of the chair has a pair of tongs, and it can be placed on the armrest, which is convenient for the user to place a drink or read a book.

In order to understand the purpose, features, and effects of this development, I will explain in detail with the attached figure through the following specific use cases.

1 is a side view of a relatively good use case of the present invention; In the use cases described as sitting and lying chairs, the product can be used as a chair in any form, which is not limited to the use of the product.

The chair 10 includes a main body 20, an all-round base 30 and a base pedestal 40. The main body 20 includes a cushion 21, a back 22, a leg support 23 and armrests 24 on both sides mounted on the cushion 21. You can lie down. The backrest 22 supports the back, and the legrest 23 allows the user to extend the leg. The backrest 22 and the legrest 23 can be tilted or raised by other devices. This part is not the focus of the product development and is not the same as it is commonly used.

Universal base 30 includes the following as in FIGS.

The upper plate 31 connected to the cushion 21 and the lower plate 32 connected to the base support 40 both have the same structure. Insert in position relative to spring 33.

At least four circular springs 33 are joined together by fixing them to the top and bottom plates 31 and 32 using spring latch 35, set screw 36 and nut 37;

Circular spring 33 is made of high carbon steel (see Fig. 2), and its physical properties can be reduced, eliminated and immediately resiliently stretched, twisted and deformed in accordance with the magnitude and direction of action of the external force within maximum elasticity. This is revived and restored to its original form. In addition, the proper size and sufficient strength can support the height required for the chair 10 and the deformation forces generated by the chair 10 and the person when exercising on the chair 10 (especially the deformation force in the category of affection). However, if the single circular spring 33 must support the chair 10, although the elasticity and flexibility of the chair 10 is improved, the stability of the single circular spring 33 is insufficient and the user is likely to tilt. For this reason, it is best to install at least four circular springs 33, taking into account stability, supporting weight and working strain. Again, the idea of a chair developer stands out.

As described above, the lower plates 31 and 32 are determined according to the arrangement of the circular spring 33 in shape, and the change of the shape is not limited. The changes are all considered in accordance with the stability and the motor function of the chair 10.

The universal base 30 of this product was originally converted into a universal rocking chair 10 with a variety of swings and tremendous resilience and versatility.

In addition, between the upper plate 31 and the lower plate 32 described above, a pleated protective cover 50 made of rubber is worn to enclose the circular spring 33 to prevent contact with the human body as well as to prevent dust or aesthetics.

4 is an explanatory view of the operation of the vertical force supported by the universal base 30. ; For the sake of brevity and ease of explanation, arrow P indicates the deformation force generated when the user is exercising on cushion 21.

Figure 4 corresponds to the phenomenon of the vertical lift occurring in the chair 10 when the human body sits on or leaves the chair 10. As the body sits on the cushion 21 of the chair 10, when P acts strongly vertically above the all-round base 30, all the circular springs 33 are equally affected by pressure and generate relative strain and stress. All circular springs 33 are simultaneously compressed by this vertical external force. When the external force P is weakened, the circular spring 33 immediately elongates to dissipate the external force, and each circular spring 33 is restored to its original state. (See left side of Figure 4)

5 is an operation explanatory diagram when a force is applied to both the left and right sides of the universal base; The direction in which the applied force P acts on the left or right side of the chair 10 corresponds to free swing of the human body from side to side on the cushion 21. If the circular spring 33 located on the side is compressed or deformed according to the magnitude of the applied force P, the other circular spring 33 is relatively deformed accordingly, and each circular spring 33 on both the left and right sides is automatically Because of its restorative characteristics and checks against each other, the base 40 of the chair 10 can remain stable without moving.

6 is an operation explanatory diagram when a force is applied to both the front and rear sides of the universal base; When a force P is applied to the front or rear side of the universal base 30, the circular spring 33, which is applied to both sides, is immediately compressed or deformed according to the magnitude and direction of the action force P. The same reason is that the circular spring 33 on the other side is also relatively It is transformed. This corresponds to the body shaking back and forth on cushion 21, much like a traditional rocking chair.

7 is an operation explanatory diagram in which a horizontal force is applied to the front and rear or side to side of the universal base at an intersection; If the force P acts horizontally back and forth or crosses right and left above the universal base 30, the cushion 21 is relatively shaken accordingly. Each circular spring 33 in the universal base 30 is then relatively twisted and restored to its original position after the action force P disappears. This is the same as the user rocking from side to side, with cushion 21 correspondingly twisting but the base 40 still does not move steadily.

8 is an explanatory view of the movement state of each side of the chair when the multifunctional chair of the present product performs irregular movement; In fact, when sitting on the chair 10, the user's sitting position, weight and shaking direction are all irregular and not simple. There may also be two or more types of exercise at the same time. For example: shake up and down or shake back and forth during vertical movement, or swing horizontally while shaking up and down while swinging up and down at will. Even at the same time up and down, back and forth, left and right unevenly shake. This type of movement feature allows the user to feel a pleasant and comfortable feeling that the circular spring 33 has the flexibility and elasticity, and never felt like floating in a cloud like blue waves. In particular, when used in love between men and women, the universal base 30 can not only support the weight of two people, but also the direction of movement according to the position of two people and the movement force that changes frequently are irregular and simple movements in the universal base 30. The resilience after the transformation helps to change the two people's movements and heighten the mood in the bed. More importantly, no matter how violent and irregular the movement of the cushion 21, the base 40 of the chair 10 still does not move steadily. In addition, the armrest 24 is provided with a direction axis so that the armrest 24 is rotated outwards to be rotated at different angles. When turned to the proper position, both legs can be supported to increase comfort when loving between men and women.

In addition, this development chair 10 can be applied to a range of office chairs, sitting and lying chairs and leisure chairs, but if the user shakes the lower back part and causes the chair 10 to move in an incorrect direction, The stiffness and discomfort of the part, waist and back are alleviated, and the shaking makes you feel comfortable and enjoyable.

9 is a structural explanatory diagram of a vibration motor provided below the cushion of the present product; This product installs the vibration motor 60 on the upper plate 31 under the cushion 21, and the flexible supporting method of the circular spring 33 and the characteristics of absorbing the vibrations make the chair 10 using the universal base 30 have a massage chair function according to the vibration. In addition, it enhances the user's blood circulation, which makes the whole body cool, and makes it easy to fall asleep to recover from fatigue.

10 is an assembly explanatory diagram for assembling the object base and the chair armrest; This product is equipped with an object stand 70. The lower part of the object stand 70 has tweezers 71 in each of the positions of the armrest 24 of the chair 10 so that the user can place drinks or books on the armrest 24. Convenient to read

The versatile base of the multifunctional chair developed this time converts the rigid support of the traditional chair into a flexible support, giving the seating person uneven direction and stable shaking and vibration, making it suitable for use in other places or sports models. It effectively improves the shortcomings of the single use function. It is also a new idea that has not been available before, and it has enough commercial value to meet the requirements of the new model patent.

The above is a detailed description of the present development, and the described part is only a relatively good experimental example of the present development and cannot be limited to the actual use range of the present invention. Mean changes and adjectives in the scope of the present application are all within the scope of patents of the present development.

The universal base of the multifunctional chair developed this time changes the rigid support of the traditional chair to the flexible support, giving the seating person uneven direction and stable shaking and vibration, making it suitable for use in other places or sports models. The physical properties of stretching, twisting and deforming, relative to force and direction of action, change the support structure of the traditional rocking chair, giving the chair more functionality and change, allowing the user to move freely and to float in the air or water. You can feel the same comfort and enjoyment as you can, especially when expressing affection between men and women.
