Description

Load Controlling Device Based on Solenoid}

The present invention relates to a solenoid-based load control device, and more particularly, by adjusting the power intensity supplied to the solenoid-based electromagnet to change the magnetic force strength between the solenoid-based electromagnet and the fixed magnet, and to apply a strong load by changing the magnetic force strength It relates to a load control device that enables high-intensity muscle strength exercise without inter-floor noise even in a home by providing it.

Due to the recent rapidly rising well-being boom and the declining age of adult diseases triggered by westernization of eating habits, society's overall desire for various indoor and outdoor exercise as well as leisure activities is being increased.

In response to this overall trend in society, various sports facilities are increasing rapidly in small and medium-sized cities as well as large cities. The fitness center is equipped with various exercise equipment, and the exercise equipment allows muscle training by a combination of a plurality of weights or spring tension.

However, as the corona era enters, people avoid gyms that gather in specific places to exercise, and most are only performing simple exercises at home.

In other words, for strength exercise, a load device such as a weight or a spring is required, but in an apartment, it is difficult to use a weight-type exercise device due to inter-floor noise problems. It is somewhat difficult to do.

Korean Patent Registration No. 10-1062438 (registered on Aug. 30, 2011; hereinafter referred to as 'Prior Document 1') suggests a fitness equipment that assists with weights. The prior document 1 is equipped with an air cylinder to assist the weight provided in the fitness equipment to provide a device that can help the user's exercise without an assistant to increase the exercise effect. However, Prior Document 1 is difficult to use in communal living environments such as apartment villas, because it still uses weights.

Korean Patent Registration No. 10-1671504 (registered on Oct. 26, 2016; hereinafter referred to as 'Prior Document 2') suggests a load control device used in fitness equipment. In the preceding document 2, when the lever connected to the wire is pulled, the weight coupled to the end of the wire on the other side is moved to make the movement, but the weight is controlled by the horizontal plate whose inclination is adjusted by the cylinder. However, since the preceding document 2 also has a weight, weight noise may be generated in the process of reciprocating the weight on the horizontal plate, so it is not suitable in a communal residential environment.

Accordingly, there is a need for a device having a new structure that can be used indoors, particularly in a multi-family house such as an apartment, by providing a load without using a weight.

1A is a schematic diagram showing a load control device according to a preferred embodiment of the present invention, and FIG. 1B is a schematic diagram showing a lower body strength exercise device equipped with a load control device of the present invention.

As referenced, the load control device 10 according to the present invention is coupled to one side of the strength training device to provide a load force, thereby enabling strength training without a weight.

The load control device 10 includes a cylindrical cylinder 20, a stationary magnetic stopper 30 coupled to both ends of the cylinder, a solenoid piston 40 moving inside the cylinder, and pulling the solenoid piston to one side. It is configured to include a pulling line 50 and a control unit 60 that supplies power to the solenoid piston to have magnetism.

The cylinder 20 is formed as a transparent tube body so that the movement of the inside can be visually confirmed from the outside, or it is made of a non-metal that can block the transmission of magnetic force to the outside to prevent the transfer of magnetic force to adjacent parts. . In addition, it is possible to prevent the rotation of the solenoid piston moving inside by forming a polygon other than the general cylindrical body to form a polygonal cross-sectional shape of the inner accommodation space.

The fixed magnet stopper 30 is a stopper coupled to both ends of the cylinder 20 to close the cylinder 20 . The static magnet stopper 30 has different polarities, so that when the solenoid piston 40 inside has magnetism, an action of pulling or pushing it to either side is generated.

As shown in FIG. 2 , the stationary magnet stopper 30 includes a stationary magnet 31 having a magnetism and a stopper body 32 surrounding the stationary magnet. The stopper body 32 contains a stationary magnet, but opens in opposite directions of the two stopper bodies disposed at both ends of the cylinder to expose the stationary magnet, and the opposite end side in the inner direction is coupled to the cylinder 20 means are formed. The coupling means may be applied with an interference fitting method, but it is preferable to apply a screw coupling method to prevent detachment during movement.

A hinge coupling part 33 is formed on the outer surface in the axial direction of the stopper body 32 . The hinge coupling part may be provided in various forms as a connection member rotatably coupled to the frame of the strength exercise machine.

In the present invention, the hinge coupling part 33 is formed only on one side of the fixed magnetic stopper 30 of both sides of the cylinder 20 to be rotatably fixedly coupled to the frame of the muscle strength exercise device, and the other fixed magnetic stopper 30 ) is configured such that the pulling line 50 is inserted.

Next, the solenoid piston 40 is mounted inside the cylinder 20 and guided to the inner wall of the cylinder so as to be movable in the axial direction. The solenoid piston 40 is formed as a plate or column having a cross section corresponding to the vertical end of the cylinder, and is electrically connected to the control unit 60 so that power is supplied by the intermittent control of the control unit. As an example, power may be supplied through the pulling line by including an electric wire in the pulling line 50 coupled to one side of the solenoid piston 40 .

When the solenoid piston 40 has magnetism by supplying power, a pulling force is applied to one side of the fixed magnet stoppers 30 due to the different polarities, and the other side has the same polarity and a pushing force is applied to each other. . Therefore, the user pulls the solenoid piston 40 in the direction of the fixed magnet stopper 30 having the same polarity to perform a muscle strength exercise.

The pulling line 50 has been described in the form of a line, but may be formed of a rod or tube body, and one end is connected to the solenoid piston 40 and the other end is a pulling action member 91 to which a pulling force acts for muscle strength exercise. For example, it is connected to a hinge rotation member or a handle.

The pulling line 50 is connected to the external pulling action member 91 by inserting a fixed magnetic stopper 30 in which the hinge coupling part is not formed, and receives the pulling force from the pulling action member to move the solenoid piston 40 to one side. Perform the exercise while pulling.

The control unit 60 is electrically connected to each part of the load control device to control whether or not power is supplied. That is, it is electrically connected to the solenoid piston 40 of the load control device so that the solenoid piston 40 can have magnetism depending on whether power is supplied or not.

In addition, the control unit 60 forms a strength control unit to adjust the power intensity supplied to the solenoid piston 40 so that the magnetic force strength between the solenoid piston and the stationary magnet 31 is adjusted, so that the load intensity provided by the load control device can be controlled.

The load control device 10 according to the present invention configured as described above forms a through hole passing through the inside and outside at both ends of the cylinder 20 or at least at the end side close to the hinge coupling part 33 to move the solenoid piston Accordingly, the internal air is discharged and the external air is introduced, so that the reciprocating movement of the solenoid piston can be made easily.

As shown in FIG. 3 , in the load control device 10 according to the present invention, a plurality of detection sensors 21 may be mounted on the inner wall of the cylinder 20 in the longitudinal direction. Since the detection sensor 21 is disposed inside the cylinder inner wall, it is possible to prevent jamming when the solenoid piston 40 reciprocates.

The detection sensor 21 may detect the passing solenoid piston 40 and transmit a detection signal to the control unit 60 to enable calculation of the movement distance of the solenoid piston 40 .

In this way, the control unit 60 receiving the signal from the detection sensor may calculate the momentum from the movement distance of the solenoid piston 40 and the magnitude of the load provided by the power intensity of the power supplied to the solenoid piston and provide the information.

In this case, the calculated amount of exercise information may be provided through the display unit 70 installed in the exercise device, or provided to a personal terminal wirelessly connected to the exerciser by providing a wireless communication unit in the control unit to be managed.

In addition, as shown in FIG. 4 , the solenoid piston 40 may further form a coating layer 41 made of plastic or synthetic resin on the side contacting the inner wall of the cylinder 20 .

The coating layer 41 is formed in a tubular shape having a certain thickness to prevent the magnetic part of the solenoid piston 40 from being directly in contact with the inner wall of the cylinder 20, and reduces friction with the inner wall of the cylinder when the solenoid piston reciprocates. Only the repulsive force of the magnetic force can make a muscular workout

In addition, it is possible to prevent the magnetic part of the solenoid piston from collided with the inner wall of the cylinder, thereby suppressing noise generation due to colliding during the reciprocating movement process.

5, a guide projection 22 or a guide groove 42 is formed on the inner wall of the cylinder 20 and the outer surface of the solenoid piston 40 to rotate about the moving axis when the solenoid piston 40 reciprocates. it can be prevented

When the solenoid piston 40 is formed in the shape of a disk or a cylinder, rotation may occur using the pull string 50 as a rotation axis, and this rotation may twist the pull string 50 . If it moves in this state, the twisted pulling string 50 may be caught by the fixed magnetic stopper 30 and break, which may cause a problem in that the load control device is damaged.

Accordingly, by preventing the rotation of the solenoid piston 40 by the guide protrusion 22 or the guide groove 42, it is possible to prevent the kinking of the pulling string 50 from occurring.

The solenoid-based load control device 10 according to the present invention configured as described above,

It is mounted on the load generating part of the muscle strength exercise device 90 to generate a magnetic force in the reverse direction to the direction in which the pulling of the user performing the exercise is generated, thereby enabling muscle strength exercise. That is, since the magnetic force can control the amount of power supplied to the solenoid piston 40 to enable control of the strength, it is possible to replace the existing weight and suppress noise generation, thereby making it possible to use it in an apartment house.

In addition, since it is possible to calculate the amount of momentum by synthesizing the amount of power supply, time, and the movement distance of the solenoid piston, it is possible to provide a useful device that can be managed by planned movement.
