Description

Technical Field

[0001] The invention relates to the technical field of sofas, in particular to a sofa for leisure and health preservation. Background Art

[0002] As a kind of furniture, sofa has certain leisure and social attributes, especially in commercial places, sofas are indispensable. In leisure industries such as foot bath and ear cleaning, customers can sit on the sofa for leisure activities. However, the sofas in the existing technology are single in function and often only have the function of a sofa, which cannot meet the needs of lying down in the same position for beauty, massage and other health activities.

[0003] Even if there is a dual-purpose sofa in the prior art that can be transformed into a bed by laying down its backrest, when the sofa is switched to the bed state, its overall height remains unchanged, and the height of a leisure sofa is generally 40 cm to 50 cm, and the height of a health massage bed is generally 60 cm to 70 cm (at this height, the therapist can exert enough force, which is convenient for exerting force and also convenient for using existing techniques and supporting conditioning tools). Therefore, simply being able to lay the sofa backrest flat still cannot meet the needs of leisure and health.

[0004] In addition, in places where massage beds are used alone, such as beauty salons, massage therapy shops, etc., due to limited commercial space, after a 2-meter-long massage bed is placed in a 3-meter-wide room, only 1 meter of walking space is left at the end of the bed (space is only left on one side to give people a sense of open space). When performing head care, the traditional practice is to place the customer on the bed with their head and feet reversed, but this brings problems of unsanitary conditions and poor customer experience.

[0029] In addition, from a business perspective, sofas are more formal and sociable and have certain business functions. Therapy beds are generally used in beauty salons, therapy facilities, etc., and usually give people the impression of being used to treat illnesses. They do not have business functions and are not easily accepted by customers in terms of business etiquette. The basic form of the present invention is a sofa mode. After customers relax through leisure activities in the sofa form, they can switch the sofa to a therapy bed to facilitate timely beauty, massage and other health-care conditioning projects, thereby attracting customers to socialize first and then maintain their health, which meets the psychological needs of customers, integrates leisure and health care, and is conducive to expanding the customer base.

[0030] At the same time, the present invention can switch between multiple modes, and different businesses can be operated in the same commercial place, saving commercial space, while effectively meeting the commercial needs of merchants, achieving the purpose of reducing costs and increasing profits.

[0031] In summary, the present invention is based on the current situation that commercial space is small but users have diverse functional requirements.
