Description

Multifunctional body-building chair

Technical Field

The utility model belongs to the technical field of equipment, and particularly relates to a multifunctional body-building chair.

Background

Currently, exercise equipment is generally classified into a single function machine and a multi-function machine. Each device of the single function machine is mainly aimed at a similar type of action. The equipment generally has the problems of relatively simple structure, low space utilization rate, single function, poor interactivity, low resistance value and the like. For example, the average floor area of the rowing machine needs about 1 square meter, and a spinning also needs to occupy a special area of about 0.5 square meter, but only one type of exercise mode can be realized. This is too large for most homes, public offices and standard hotel rooms.

For existing household multifunctional exercise equipment, the equipment is generally required to be fixed on a wall or provided with stability by the heavy weight of the equipment. This causes a problem that the requirements for installation conditions and use conditions are relatively high. In addition, there is a need for a relatively large number of lifting and stretching exercise devices, which basically rely on the weight of the exerciser or external counterweights to achieve resistance. The device which forms resistance by the weight of the user has a simple structure, the resistance is not easy to adjust, the device which forms resistance by the counterweight has high noise in the process of putting down the counterweight after lifting, the other people are affected, and the volume and the cost of the body-building device are increased by a large number of counterweights, so that the device is not suitable for daily exercise with medium strength in families and offices.

Some motor resistance exercise machines are also recently available on the market. The products are one motor corresponding to one resistance rope (such as a rowing machine with resistance or electromagnetic resistance) or two motors corresponding to two resistance ropes (TONAL, IMBODY training machines). While a multi-function exercise machine needs to be able to provide more than three resistance cords for movement in different positions. If a plurality of motors are adopted, the equipment cost can be increased, the control is more complex, the weight and the volume can be increased, and the use is inconvenient. Thus, there is a need for one or several related new devices or apparatuses.
