CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority of Colombian Patent Application No. NC2021/0003433, filed Mar. 17, 2021, which is incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates to a multifunctional system or device for exercise, therapy, sports, recreation and alternative transportation for adults with or without disabilities, especially older adults.

SUMMARY OF THE INVENTION

The present invention is directed to a tricycle-type system or device for adults (called Tr&Seven01 TEAM), Ergonomic, Assisted, Multifunctional that can be activated by two users simultaneously from three points of mechanical traction and assisted with an electric motor, as desired by the users, where said tricycle-type system or device can be adapted for people with some types of disabilities, the elderly, people with normal mobility or coupled for loading.

STATE OF THE ART

Static and mobile systems or devices for rehabilitation, therapy and transportation purposes are known. Within the static devices, Colombian patent NC2017/0005734 teaches an assisted rehabilitation system of the static bicycle type along with devices that automatically sense and manipulate the body's performance parameters that allow an optimization in the response process to the rehabilitation of a patient.

Regarding mobile devices, patent CO15271525 reports a seesaw-type system comprising a main body for two people who use it standing up and drive the system by pedaling. The device can have two or three wheels and the two people both standing facing forward, one behind the other, each at the end of the pedal, lever or rocker and where the person behind is holding on to a fixed rudder and the person in front has the direction through a movable rudder or handlebar.

International patent application WO2021/003527 is also known, which refers to a means of physiotherapeutic transportation comprising a forward mounted wheel, a frame relative to which said forward coupled wheel is mounted, a seat mounted relative to said frame on a seat support, a rear axle associated with a pair of first and second outwardly disposed rear wheels and a steering assembly associated with said pair of outwardly disposed rear wheels, wherein said steering assembly comprises a steering mechanism operable to adjust the orientation of the rear wheels.

On the other hand, document U.S. Pat. No. 5,501,476 shows a therapeutic wheeled vehicle suitable for strengthening the hip extensor muscles of a user. The vehicle combines the therapeutic benefits of conditioning the hip extensor muscles with the pleasurable activity of being propelled on a wheeled vehicle. A frame is provided which follows the general pattern of a tricycle with one steer wheel and one pair of drive wheels. A seat, a backrest and at least one strap for holding the user in position on the seat and backrest are also provided. These user support structures hold the user securely in the proper operating position, even when the user has less muscle control and strength than normal. Structures are included for receiving at least a portion of the user's leg between the user's knee and the user's hip and for transmitting the extension movement of the user's hips to the rotational movement of the pair of drive wheels.

For its part, document US2007/0187164 provides a scooter-type tricycle with variable wheels capable of being configured from a two-wheeler to a three-wheeler and vice versa, according to requirements. The scooter includes a frame for holding and carrying a rider or passenger and containing a battery and controller; a steering assembly mounted at the front of the frame for pivoting in left and right directions for steering, the steering assembly having a lower part on which a front wheel is rotatably mounted and an upper part provided with a handle for the driver to steer, a brake lever, actuator control lever and throttle grip; a bracket formed at a rear end of the frame in one piece, the bracket having a first mounting part at one end and a second mounting part at the other end; a first drive unit removably mounted to the first carrier mounting portion for a two-wheel configuration or to the second carrier mounting portion for a three-wheel configuration.

Additionally, patent CN211519734 teaches a tricycle comprising a front frame, a rear frame and a tricycle carriage, a handle of the tricycle front frame is arranged at the top of one end of the front frame; a mesh basket is attached to one side of the handle of the front frame of the trike; a front wheel fixing frame is disposed at the bottom of one end of the front frame of the tricycle.

In this sense, it is evident that a multifunctional tricycle-type device or system for adults is required, in which the rear seat can be folded to load or place a person with normal mobility, or an older adult or a person with some type of disability, wherein the tricycle-type device is ergonomic, assisted and has double traction and can be operated from three pedaling points, that is, a rear mechanical chain traction train, pedal and an electronic front assisted traction.
