Description
Technical Field
The present invention relates to a movement apparatus for helping growth by stretching and stimulating a knee joint part, and more particularly, to a movement apparatus for helping growth by providing a stretching effect by providing a traction force to a thigh, a calf and a surrounding part of a knee joint of a human body, and by applying vibration stimulation or low frequency stimulation or knocking stimulation or the like to stimulate muscles, ligaments and growth plates connected to a juvenile knee joint in a growing period while providing a warming effect to a knee socket part, and by relaxing muscles around the knee joint, and more particularly, by applying a traction force in a state of being closely adhered in a large area according to the shape of the thigh and the calf.
Background
Recently, with the lack of exercise and an increase in sedentary time, even in children and young children in the growth period, problems due to abnormal muscle bones or slow growth become more serious, and the best method for preventing this is to strengthen the muscles around joints or muscle bone systems by appropriate exercise and stretching exercise, and to treat them by self-healing force.
In addition, the growth plate is a portion of the bones of the limbs where growth occurs, is located at both ends of the bones, has the shape of cartilage tissue sandwiched between the bones, and is formed of cartilage in all the bones of the limbs in the fetal period, but as the body grows, the middle portion of the cartilage becomes bone and gradually spreads to both ends, which is called an initial ossification center, so that cartilage cells located at the growth plate are actively divided while cartilage in the middle and both ends of the bone gradually becomes bone, the remaining cartilage in the middle becomes the growth plate, and then, as puberty passes, the growth plate also becomes bone, and growth of the length ends. Factors influencing cell division of chondrocytes located in growth plates include genetic factors, nutrition, holomorph, exercise, mechanical stimulation, and the like, and among them, it is well known that the extent of growth of 70% or more is influenced by acquired factors. Therefore, as the fetus grows to puberty, it is important to provide sufficient nutrition, proper exercise and mechanical stimulation, and for this purpose, acupressure and massage methods of the growth plate for stimulating the leg bones associated with height growth using various exercise methods and stretching effects have been proposed.
However, the conventional exercise method has a disadvantage that it is difficult for children and teenagers who are busy in the academic industry to perform because of the regular exercise amount and time required, and the therapy cannot be performed by the person who receives the therapy alone in most cases when the acupressure and the massage are received, so that it is inconvenient to seek help from other persons, and there is a problem that the effect is not uniform because the exercise is performed by means of manpower. In order to improve these problems, various types of acupressure massage machines that can self-accept acupressure and massage are developed and used, and among them, a vibration massage machine that vibrates an acupressure device using a driving source and an air pressure massage machine that uses air pressure are the most commonly used ones.
In the conventional vibration massage device, since the finger pressure device is vibrated by a driving source such as a vibration motor or a solenoid, the vibration massage device often uses a method of repeatedly striking (knocking) a body part, and thus, there is a disadvantage that not only is the effect of the finger pressure low, but also secondary pain is generated due to the knocking, and in order to accurately transmit the vibration of the finger pressure device to the body, the finger pressure device must be pressed against the body part with a predetermined force, which causes not only great discomfort during use, but also difficulty in continuous use due to the effort.
On the other hand, in the pneumatic massage device, the compressed air generated by the pump is repeatedly applied to the band around a part of the body of the user, and most of the bands are provided around the body part such as the arm, leg, waist, or the like of the body, and the air is injected into and discharged from the band to repeatedly apply pressure to the body part, so that any effect by stretching cannot be expected other than the application of pressure to the body part.
As a prior art, korean patent No. 10-1950148 discloses a 'growth plate stimulation massage providing device for promoting growth and development', which has disadvantages of being limited in installation space and use space due to its complicated structure and large volume. In particular, the leg massage device composed of the upper air bag, the middle air bag, and the lower air bag simply massages the lower leg, and therefore, there is a problem in that an effective extension effect around the knee joint cannot be expected to promote the height increase.
As another prior art, korean patent laid-open No. 10-2178061 proposes a "massage apparatus capable of stimulating and stretching a growth plate for teenagers in a growing period", which has disadvantages of not only being limited in installation location but also being expensive to manufacture and expensive since a user must use it while sitting, and the structure is complicated and large. In particular, the air bag surrounding the user's leg is in a bag shape inflated by receiving only air, and thus cannot be closely adhered to a curved portion of the human body, resulting in pain due to the local application of excessive pressure, which not only causes injury, but also causes stimulation due to the simple inflation and deflation of the air bag, and the structure of the calf module is extended due to the measurement of the leg length using the sensing device, and thus, there is a problem in that it is difficult to provide effective stimulation to the growth plate distributed around the knee joint. As an example, when the legs of a human body taper from the thighs to the ankles, the shank portion may take on a partially protruding shape due to muscles, and the air bag according to the related art is provided in a straight tube shape capable of being inserted into the legs, or is provided in a structure on which the portion of the "U" -shaped supply leg may be placed, so that eventually, since the air bag is not tightly adhered to the leg shape of the human body, a high inflation pressure may be applied to the thighs or the upper portion of the shanks when the air bag is inflated, and since a low pressure is applied to each lower portion, it is not only difficult to achieve an appropriate massage function, but also uniform tight pressure cannot be applied to each body portion having the thigh module and the shank module, thereby causing an uncomfortable problem due to inconvenience and pain during use.

Fig. 6 is a block diagram for explaining the present invention, and fig. 7 is a block diagram for explaining a control structure of a controller of the present invention.
The figure shows: a first air pressure sensor 91 and a second air pressure sensor 92 mounted on the pipes of the first solenoid valve 32 and the second solenoid valve 52 for measuring the internal air pressures of the upper limb air bag 33, the lower limb air bag 35 and the telescopic air bag 53; and a controller 90 electrically connected to the first and second air pressure sensors 91 and 92 to receive detection information, and applying signals for controlling operations to the first and second air pumps 31 and 51 and the first and second solenoid valves 32 and 52.
The controller 90 of the present invention includes: a fixed control unit 95 for controlling the air supply to the upper limb air bag 33 and the lower limb air bag 35 based on the detection signal of the touch sensor 77; a traction control part 96 for generating traction force for pulling thighs and calves of a user in opposite directions by widening a gap between the upper limb support 13 and the lower limb support 15, thereby generating an extension effect; a knee socket stimulation control part 97 that applies a control signal to a vibration motor, a low frequency electrode, or a solenoid actuator to apply vibration stimulation or electrical stimulation to a knee socket part behind the knee of the user's body; and a traction control portion 96 for providing stretching and massaging actions by repeating the injection and discharge of air into and into the telescopic airbag 53.
With reference to the above drawings, the structure of the exercise apparatus for helping growth by stretching and stimulating the knee joint part according to the present invention will be described.
The invention comprises the following steps: a main body 10 which is formed substantially as an outer body, provides a space for mounting various components and electronic devices, and has an upper limb supporter 13 and a lower limb supporter 15 having a front surface, a rear surface and an upper surface opened to accommodate thighs t and calves c of a user's body, respectively; a band 30 mounted on the main body 10 to temporarily restrain and fix thighs t and calves c of a body part of a user using air pressure; an extension module 50 for adjusting a gap between the upper limb support 13 and the lower limb support 15 by using air pressure and a return spring 55; and a controller 90, which is a control element for controlling the action of the knee socket stimulation module 70 for applying vibration stimulation or electrical stimulation to a knee socket region behind the knee in the user's body part.
The main body 10 includes: a bottom plate 11 formed in a plate shape to be placed on the ground; and an upper limb support 13 and a lower limb support 15 provided on the upper portion of the base plate 11 so as to be slidable in the front-rear direction.
The bottom plate 11 is formed by injection molding a synthetic resin material, and has a plate shape having a slip-preventing pad or a plurality of protrusions formed of a friction material for preventing slip at the lower surface, and a plurality of rail grooves (not shown) for guiding the upper limb support 13 and the lower limb support 15, which will be described later, in the longitudinal direction in the front-rear direction at the upper portion.
The upper limb support 13 is formed with a rail protrusion (not shown) formed on the upper portion of the base plate 11, inserted into a rail groove, and slid in a shape having an open upper surface, front surface, and rear surface, so as to accommodate the thighs t of the user's body.
The lower limb support 15 is provided at a side of the upper limb support 13 at a distance therefrom, is slidably inserted into a rail groove of the base plate 11, is capable of being displaced in the front-rear direction, and is formed in an open shape of the upper, front and rear surfaces, thereby being capable of accommodating the lower leg c of the user's body.
These upper limb support 13 and lower limb support 15 are moved close to each other or are moved apart in opposite directions by an extension module 50, which will be described later, thereby applying traction to the thighs t and calves c of the user.
The cuff 30 is provided as a member provided in each of the upper limb support 13 and the lower limb support 15 to tightly press and fix the thigh t and the calf c by air pressure, and has an upper limb air bag 33 and an upper limb pad 37 in the upper limb support 13 and a lower limb air bag 35 and a lower limb pad 39 in the inner side of the lower limb support 15.
The upper limb airbag 33, which is an airbag connected to the first air pump 31 through a pipe and inflated by receiving air pressure, may be coupled and fixed to the inner side surface of the upper limb support 13 to be inflated in a shape surrounding the back and both sides of the thigh t of the body when air pressure is supplied. The upper limb bladder 33 is connected to the first solenoid valve 32 through a pipe for discharging the filling pressure to the outside, and at this time, the first solenoid valve 32 is operated by receiving a control signal from a controller 90, which will be described later, and is implemented using a well-known technology, and thus a detailed description will be omitted.
The upper limb support pad 37 is provided as a flexible and elastic sealing bag-like member integrally provided on the inner side surface of the upper limb balloon 33, and is filled with 30 to 90% of a liquid, gel or granular fluid substance. When an external force is applied to the upper limb support pad 37, the internal fluid substance is easily moved and is easily subjected to a form displacement, and therefore, when the upper limb balloon 33 is inflated in a state where the thigh t of the user is accommodated, the internal fluid substance flows along the curved surface of the thigh t and is deformed in a close contact therewith. That is, since the upper limb balloon 33 is provided in a tubular shape made of synthetic resin fabric, there is a disadvantage in that it cannot generate uniform pressure in response to a curved surface of the body when inflated by air pressure.
As an example, the thighs of the body become thicker from just above the knees to the buttocks, and when inflation is achieved by air pressure, a relatively thicker portion near the buttocks than above the knees is subjected to a relatively higher air pressure, which causes local pain and discomfort, which makes it impossible to restrain and fix the entire thigh t in a uniformly abutted state during traction.
Accordingly, in order to solve the above problem, the present invention provides an upper limb support pad 37 on the inner side of the upper limb bladder 33, wherein the upper limb support pad 37 can be freely changed in shape by the flow of the internal fluid material, and as shown in fig. 5, the curved part of the body can be compensated.
The lower limb balloon 35 is connected to the first air pump 31 and the first electromagnetic valve 32 through pipes to receive air pressure to be inflated or to discharge internal air to the outside, and is engaged and fixed to the inner side surface of the lower limb support 15, and inflated in a shape surrounding the back and both sides of the lower leg c of the body when air pressure is supplied, like the upper limb balloon 33.
The lower limb abutment pad 39 is provided in the shape of a sealed bag integrally provided on the inner side surface of the lower limb balloon 35, and preferably, a bag made of silicone or polyurethane may be used. Such a lower limb balloon 35 is internally filled with 30% to 90% of liquid, gel or granular fluid material and is deformed due to the fluid material being susceptible to external forces. That is, as the thickness of the lower leg increases gradually from the ankle portion of the body, the lower limb cushion 39 is uniformly adhered to the entire lower leg when the air pressure is supplied to the lower limb bladder 35, and the fluid substance in the inside moves along the curved surface of the body, eventually compensating the curved portion and achieving the entire uniform close contact as illustrated in fig. 5.
The extension module 50 is provided between the upper limb support 13 and the lower limb support 15, and is configured substantially by an extension airbag 53 and a return spring 55 as elements that push or return to a position close to each other in a direction of being spaced apart from each other.
The telescopic airbag 53 is provided in a plurality of structures in a space and a position not interfering with the space for placing the thighs t and the calves c of the user, and is inflated as a traction element by receiving air pressure from the second air pump 51 connected through a pipe, thereby sliding the upper limb support 13 and the lower limb support 15 apart from each other.
The expansion/contraction bag 53 is connected to the second electromagnetic valve 52 via a pipe, so that the air filled in the interior can be discharged to the outside, and at this time, the second electromagnetic valve 52 receives a control signal from a controller 90 described later, and performs the opening/closing operation of the valve, which can be performed by a known technique, and therefore, a detailed description thereof is omitted.
The return spring 55 is installed at a position not interfering with the telescopic airbag 53 so that an elastic contractive force is applied when the internal air pressure is discharged through the second electromagnetic valve 52 in the expanded state of the telescopic airbag 53, and thus, the upper limb support 13 and the lower limb support 15 are moved close to each other. Various known techniques may be applied as long as the return spring 55 has a characteristic of providing an elastic contractive force, and a coil spring shape is proposed as a preferred embodiment of the present invention.
The knee foster module 70 is provided in a space between the upper limb support 13 and the lower limb support 15, and the knee foster module 70 includes: a lifting spring 71 provided at an upper portion of the base plate 11 at a position where a knee socket is located when a user puts a leg on the upper limb support 13 and the lower limb support 15 so as to apply an elastic supporting force in a vertical direction; a knee socket contact pad 73 provided on the upper portion of the lifting spring 71; and a stimulus generating unit 75 and a touch sensor 77 provided on the upper portion of the contact pad 73.
As shown in the drawing, the lifting spring 71 has a lower portion fixed to the base plate 11 and an upper portion disposed in a vertically upper direction, and the lifting spring 71 is adapted to elastically support when a user puts the leg on the body 10, so that the touch sensor 77 can be in contact with one of a vibration motor, a low frequency electrode, or a solenoid actuator that provides the stimulation generating part 75 to the knee socket part.
The knee socket contact pad 73 has an enlarged volume at an upper portion of the lifting spring 71, is filled with a fluid substance such as particles, liquid, gel, etc., and the outer case is made of a flexible and elastic material such as silicone or polyurethane. A heater or a heating element such as an LED that generates heat by receiving electric power from the outside may be further provided inside the knee socket contact pad 73.
The stimulation generating part 75 is used to apply stimulation to the knee fossa portion of the portion behind the knee of the user, and in the present invention, one or a combination of more than one of a vibration motor, a low frequency electrode, and a solenoid actuator may be used.
On the other hand, among the elements supplied to the stimulus generating section 75, the vibration motor operates as an element that receives electric power from the outside and applies physical vibration stimulus by receiving a control signal from a controller 90 described later. One or more of the vibration motors are provided at one side of the upper face of the knee socket contact pad 73 to be in contact with the knee socket part of the body, and thus detailed description will be omitted since it can be performed using known techniques.
The low-frequency electrode is operated by receiving a control signal from a controller 90 described later as an element that receives electric power from the outside and applies electric stimulation. One or more of the low frequency electrodes are provided on the upper side of the knee socket contact pad 73 to be in contact with the knee socket part of the body, and since it can be performed using a well-known technique, a detailed description will be omitted.
In addition, the solenoid actuator is headed by a plunger driven by a coil provided in an axisymmetric structure around which a current is applied, a housing surrounding the outside of the plunger, and a core inside of the coil, so that the plunger is ejected by a magnetic force generated in a gap between the plunger and the core, a striking body provided at an end of the plunger applies a physical striking stimulus to a knee socket portion, and is operated by receiving a control signal from a controller 90 described later. One or more of the solenoid actuators are provided on the upper side of the knee socket contact pad 73 to form a striking finger pressure member so that the end of the plunger rod is in contact with the knee socket part of the body, and since it can be performed using a well-known technique, a detailed description will be omitted.
The touch sensor 77 is provided on the upper surface side of the knee socket contact pad 73 as a capacitance sensor for detecting contact with the skin of the human body, so as to prevent interference with the positions of the vibration motor, the low frequency electrode, and the solenoid actuator constituting the stimulus generating section 75. The touch sensor 77 is electrically connected to a structure for applying a detection signal to a controller 90 described later, and a detailed description will be omitted since it can be performed using a well-known technology.
The controller 90 is connected to a first air pressure sensor 91, a second air pressure sensor 92, and a timer 93 for measuring time for applying operation control signals to the first air pump 31, the second air pump 51, and the first solenoid valve 32, the second solenoid valve 52, and the stimulus generating section 75, wherein the first air pressure sensor 91 and the second air pressure sensor 92 are installed on the pipes of the first solenoid valve 32 and the second solenoid valve 52 for measuring the internal air pressures of the upper limb air bag 33, the lower limb air bag 35, and the telescopic air bag 53, and the stimulus generating section 75 is constituted by one or more of a vibration motor, a low frequency electrode, or a solenoid actuator. The controller 90 is generally composed of a fixed control unit 95, a traction control unit 96, a knee fossa stimulation control unit 97, and a repetitive traction control unit 98.
The fixing control unit 95 receives detection signals from the capacitive touch sensor 77, and inflates the upper limb airbag 33 and the lower limb airbag 35 to restrain and fix the thighs t and the calves c of the user in contact with the upper limb pad 37 and the lower limb pad 39. That is, when the capacitive touch sensor 77 detects physical contact of the user, the stationary control part 95 applies a control signal to the first solenoid valve 32 to generate air pressure and supply it to the upper limb air bag 33 and the lower limb air bag 35.
In addition, the fixed control part 95 is electrically connected to a first air pressure sensor 91 for measuring the internal air pressures of the upper limb air bag 33 and the lower limb air bag 35 so that the pressure value is received in real time and the first air pump 31 is driven and controlled until the air pressures in the upper limb air bag 33 and the lower limb air bag 35 reach a preset value.
When the user places the leg on the body 10 and touches the knee socket portion behind the knee to the touch sensor 77, the fixation control part 95 of the structure inflates the upper limb airbag 33 and the lower limb airbag 35 to restrain and fix the thigh t and the calf c of the user.
When the fixation control portion 95 completes the inflation of the upper limb airbag 33 and the lower limb airbag 35, the traction control portion 96 applies a control signal to the second air pump 51 so that air pressure can be supplied to the telescopic airbag 53. At this time, since the internal air pressure of the telescopic air bag 53 is measured by the second air pressure sensor 92 in real time, the traction control portion 96 of the present invention performs the comparison process until the air pressure value measured by the second air pressure sensor 92 reaches a preset value, thereby controlling the driving of the second air pump 51.
The traction control unit 96 having such a structure expands the plurality of telescopic airbags 53 to move the upper limb support 13 and the lower limb support 15 in directions spaced apart from each other, and finally, the thighs t and the calves c of the user are pulled in opposite directions, thereby achieving the stretching action by traction.
The knee fossa stimulation control unit 97 is provided as a control means for applying power to the stimulation generating unit 75 to stimulate the knee fossa when the traction operation of the traction control unit 96 is completed, and in the present invention, the operation is performed after the completion of the operation by the traction control unit 96, but the present invention is not limited to this, and the vibration motor may be started after the completion of the operation by the stationary control unit 95.
That is, when the stimulation generating section 75 is a vibration motor, the knee fossa stimulation control section 97 outputs a control signal to apply electric power to the vibration motor to perform physical vibration stimulation to the knee fossa site. In addition, when the description is made of the case where the stimulation generating unit 75 is a low-frequency electrode, a control signal is outputted to apply electric power to the low-frequency electrode to perform electric stimulation on the knee fossa portion. When the above description is made of the case where the stimulation generator 75 is a solenoid actuator, the knee socket stimulation controller 97 outputs a control signal to apply power to the solenoid actuator, and the knock stimulation is performed by repeating the operation of ejecting the plunger and the rod to the knee socket.
The repetition traction control unit 98 is a control element connected to the second air pressure sensor 92, and when the inflation of the telescopic air bag 53 is completed, a control signal is applied to the second electromagnetic valve 52 to discharge 50% to 90% of the air in the telescopic air bag 53, and when the upper limb support 13 and the lower limb support 15 are moved in the direction approaching each other, after a predetermined time elapses, air is again injected into the telescopic air bag 53 until reaching a predetermined value, and the upper limb support 13 and the lower limb support 15 are moved away again in the direction separating from each other, thereby improving the extension effect by repeating the above-described operation. That is, the repetition traction control part 98 is connected to the timer 93 so that air is injected into or discharged from the telescopic airbag 53 for a set time, and a control signal is applied to the second air pump 51 and the second electromagnetic valve 52.
On the other hand, the present invention may further comprise a body temperature detection sensor for detecting the temperature of the lower leg or thigh of the user, which measures the body temperature of the user at predetermined time intervals, and when the body temperature is suddenly changed, the first solenoid valve 32 and the second solenoid valve 52 are opened to stop the operation of the device to discharge the air in the upper limb air bag 33 and the lower limb air bag 35, and the driving of the knee fossa stimulation module 70 is stopped, which may be programmed to be controlled in the controller 90
In addition, a blood pressure measuring sensor (not shown) may be provided in addition to the body temperature detecting sensor, and the blood pressure measuring sensor may measure the blood pressure of the user at predetermined time intervals as in the body temperature detecting sensor, and when a sudden change in blood pressure occurs, the operation of the device is stopped, a warning sound is output, an LED lamp is turned on, and the like, so that safety in use is ensured.
The exercise device for assisting the growth by the extension and stimulation of the knee joint part according to the present invention constructed as described above, the user puts his/her own leg on the main body 10, places the thigh t part in the upper limb support 13, and places his/her own knee socket part in contact with the knee socket stimulation module 70 in a state where the shank c part is placed in the lower limb support 15. Then, when the leg is lowered, the touch sensor 77 constituting the knee socket stimulation module 70 is contacted at the knee socket site and the contact state is detected.
Then, the controller 90, which is electrically connected to the touch sensor 77, supplies air to the upper limb airbag 33 and the lower limb airbag 35 provided inside the upper limb support 13 and the lower limb support 15 to restrain the fixed thigh t and the calf c.
When the restraint fixation of the user's thigh t and calf c is finished, the controller 90 applies a control signal to the extension module 50 to supply air pressure to the telescopic air bag 53, and pulls the thigh t and calf c portions in opposite directions based on the user's body knees by moving the upper and lower limb supports 13 and 15 in opposite directions, thereby providing stimulation by extension.
In addition, with the extension operation, the controller 90 applies a control signal to the knee socket stimulation module 70 to drive the stimulation generating unit 75 (vibration motor, low frequency electrode, solenoid actuator), and by applying a warming effect accompanied by vibration stimulation or electrical stimulation to the knee socket portion of the knee joint, it is possible to provide a composite and appropriate stimulation to the surrounding muscles including the knee joint and the growth plate.
In particular, the present invention starts the operation after the detection of the touch sensor 77, and thus, can be safely used, and the upper limb pad 37 and the lower limb pad 39 can be uniformly and tightly fixed to the curved thigh t and the shank c.
