Description

Multipurpose body-building apparatus

Technical Field

The invention relates to a multipurpose fitness device, and belongs to the technical field of fitness equipment.

Background

At present, the targeted exercise by means of the apparatus is favored by many fitness people, and the development of the fitness industry in China is rapid, the potential is huge, and the demand on the fitness apparatus is increasing day by day. Research shows that the heavy-weight anti-resistance exercise devices such as bench presses, deep squats and the like lack corresponding protection assistance measures, so that an exerciser is easy to be injured and even an accident is caused. For example, in the case of a lying-down device, the exerciser lies down and pushes the barbell with both hands to move up and down. Sometimes, the exerciser can appear the emergency such as exhausted, can't rely on self strength to maintain the balance and lift the barbell, can appear even causing the barbell landing because the hand is smooth, pounded the exerciser, cause the accident.

Research shows that the anti-resistance exercise devices with large weight such as bench press, deep squat and the like lack corresponding protection measures. Even some domestic and foreign famous brands such as Life Fitness, Technogym, squat frame or Smith machine which are put into practical use in gymnasiums are mostly provided with only one pair of protective rods which are arranged on two sides and can receive barbells which slide down due to hand sliding or other accidents, as for the power assisting function, almost no product has the function, and most of the products provide power assisting protection for the barbells by the companions.

In the prior art, the bench press frame or related instruments are improved aiming at the situations, most of the functions are single, only the protection function is provided, and the technical disclosure with the assistance function is not provided at present. The position of the protective rod in the protective function can not be automatically adjusted along with the movement range of the barbell of the exerciser, so that the movement range of the exerciser is limited, and the practicability is not strong; the helping hand function often needs the manual start of exerciser, artifical helping hand, and response speed is slow, can not provide the helping hand function for the exerciser in time, and secondly, the implementation of helping hand function is only hung the barbell by a wire rope and is realized in some technologies to safe and reliable not, finally, most helping hand function's helping hand size can not be adjusted by the exerciser subjectively in the exercise process, for example utilize devices such as spring to carry out the helping hand. Therefore, the existing resistance exercise equipment or device with large weight does not have a reliable, effective and practical safety protection function, and the exerciser can not be guaranteed to carry out efficient body-building exercise on the premise of guaranteeing personal safety.

As shown in fig. 8, when the present application is used, the exerciser takes out barbell 5 from groove 41, and at this time, the blocking of photosensor 44 in groove 41 is released, and the device is activated. The exerciser exercises, the barbell 5 moves up and down, the distance between the bracket 43 and the barbell 5 can be measured by the grating 42 on the surface of the bracket 43 every other pulse, then the PLC control module judges the distance value, for example, the distance value in the program can be limited to 15-25mm (the distance value range can be freely set according to actual conditions) when in use, if the distance value exceeds or is not within the range, the driving motor 61 is enabled to rotate forwards or backwards, the bracket 43 is enabled to ascend or descend, and if the distance value is within the range, the driving motor 61 is kept still, and the driving motor 61 is stopped. In a normal operating state, the blue indicator light 8 is on.

When barbell 5 slips off the hands due to a hand slip or other accident, since grating 42 can measure a distance value every other pulse, the difference between two adjacent distance values is divided by the pulse time period to obtain the average velocity of movement of barbell 5 during the pulse time period, the speed value is judged, because the barbell 5 is in a falling state, the distance difference value in the program is the distance minus the last distance, the difference is a negative value, the measured speed value is also negative, the speed value is judged to be less than or equal to the safety limit speed (the safety limit speed can be freely set according to the actual situation), the purpose of calibrating the speed without absolute value is to prevent the exerciser from lifting barbell 5 upwards too fast, which results in a positive speed value being too large, which results in misjudgment, if the safety limit speed is exceeded, motor 61 is immediately stopped and carriage 43 immediately stops and catches falling barbell 5. In the scram function of the bracket 43, the red indicator light 8 is turned on.

When the exerciser can not actively lift the barbell 5 due to exhaustion, the exerciser steps on the pedal 7 at the moment, the PLC control module is converted into a torque mode from the speed modes of the first two functions, the power assisting amount can be controlled by the stepping depth of the pedal 7 at the moment, when the exerciser steps on the pedal 7, the stepping depth of the pedal 7 is converted into a voltage value, the voltage value is increased along with the increase of the stepping depth, and the voltage value is converted into a variable for controlling the power assisting amount in the PLC control module. The judgment of the ascending or descending of the bracket 43 is carried out next, because the exerciser can complete several exercise actions after the power assisting function is started, the power assisting bracket 43 is required to be incapable of always assisting upwards and also to ascend to the top and then to descend. This determination function is determined by two photoelectric switches provided on the linear guide 66, and the exerciser adjusts the position of the photoelectric switch before exercising to approximately raise a range of motion of the barbell 5, and after the booster mode is turned on, the carriage 43 is shifted up to the upper photoelectric switch, and the variable for controlling the magnitude of booster is negative, and if the lower photoelectric switch is shifted down, the variable for controlling the magnitude of booster is positive. If the value is negative, it means that the carriage 43 moves to the upper limit position, and the driving motor 61 rotates reversely, so that the carriage 43 descends; if the value is positive, the lower limit position causes the carriage 43 to move upward. The larger the absolute value of the variable for controlling the magnitude of the assisting force is, the larger the torque, i.e. the assisting force is. In the boost mode, the green indicator light 8 is on.

This application adopts sensitive sensing and transmission, structural ingenious design for have automatic rising follow, scram, have the helping hand function concurrently simultaneously. The invention realizes the anti-resistance exercise of heavy weight, and provides necessary assistance and protection according to the requirement of an exerciser, thereby ensuring the personal safety of the exerciser.
