Description

English Description DescriptionTitle of Invention : Leg Flexibility Device with Hot and Cold Actuator FluidTechnical Field

[0001] The present invention relates to sports assistive devices and is applicable in the field of flexibility-based sports and exercises.Background Art

[0002] In the prior art relating to leg flexibility, several types of leg stretching devices are known in which an athlete sits on the device and the device spreads the athlete’s legs symmetrically. Various models of such devices, both manual and electric, are available in global markets. These stretching devices are limited to opening the legs and do not provide any method or technique for relaxing the muscles during the stretching process in order to prevent muscle pain. By searching the term “leg stretching device,” examples of such devices can be found on the internet.

[0003] One approach used in claimed devices involves the application of heat by means of a fluid. In the existing knowledge, various heating elements such as silicone wire heating elements or thermotherapy systems may be used.Additionally, electrotherapy may be employed to reduce muscle pain. For cold application, instead of using a cold fluid medium, cooling modules may be positioned at different muscle locations or cold air may be applied. Furthermore, for massage, conventional electric massage devices may be used instead of the mechanical massage components employed in the present invention. For leg stretching and flexibility, techniques such as reciprocal inhibition and PNF may be adopted; however, due to excessive complexity, these techniques have not been used in the present device.

[0004] The invention with publication number CN217163061 has been filed at the China Intellectual Property office. According to the disclosure, it is equipped with a massage subassembly configured to rotate along the inner upper surface in sliding engagement, which is located at the bottom of the seat. By providing a transmission assembly, the system is capable of driving two rotating elements toEnglish Description rotate in the same direction, thereby enabling the seat to achieve equidirectional rotation and consequently allowing the lower legs to realize a tensile effect. In this invention, no reference is made to the use of music, fluid, heat, or cold.Summary of Invention

[0005] By combining massage and heat application to the muscles, blood circulation is increased, oxygen delivery is improved, lactic acid is reduced, the sensitivity of neural receptors is decreased, and muscle relaxation is achieved. In addition to heat and massage, cold application may also be used to enhance performance and further reduce pain. The combination of heat and cold may be applied as contrast therapy. Furthermore, in order to provide an improved sensory experience during the stretching process, the secretion of endorphin hormones (happiness hormones) may be stimulated through music synchronized with the massage rhythm.

[0006] By integrating the aforementioned methods, namely heat, cold, massage, music, and stretching, the present invention enables leg flexibility with a significant reduction in pain and prevention of groin injuries. Moreover, the massage components and the heat and cold delivery mechanisms differ from conventional systems; instead of commonly used electric vibration motors and massage devices, the invention employs components and a mechanism that operate without direct electrical power and are actuated solely by the flow of a hot or cold fluid to generate movement and perform massage.Technical Problem

[0007] The objective of the present invention is to significantly reduce pain during leg stretching and flexibility exercises and to prevent injuries to the groin region.Based on personal experience and a review of scientific sources such as Guyton Medical Physiology, it is established that one of the causes of pain in muscle tissue is the presence of a chemical compound known as lactic acid, which accumulates in muscle tissues due to intense physical activity and insufficient oxygen supply.

[0008] One solution to this problem is to apply massage to the target area at an appropriate time. In addition, the application of hot and cold fluid compresses canEnglish Description assist in alleviating muscle tissue pain. Furthermore, inducing the secretion of endorphin hormones in the user’s body can contribute to improving the user’s overall sensation and comfort.Solution to Problem

[0009] In order to solve the existing problem, the device employs a combined method and mechanism for gentle leg flexibility, which includes heat application, cold application, massage, and music synchronized with the massage rhythm, performed simultaneously with stretching. For massaging the user’s legs, mechanical massage components are used, wherein the driving force that generates movement in these components is a moving hot or cold fluid. In fact, in this device, the fluid is used for two purposes: first, for transferring heat or cold, and second, for actuating the mechanical massage components. The fluid may be water or any other suitable fluid.

[0010] For heat application, an 8-liter fluid reservoir (1) is used, which is positioned behind the seat backrest. This reservoir includes a heating element (8) for heating the fluid and an inlet (9) for filling the reservoir, two 24-volt 100-watt pumps (3) for transferring the fluid in the left half of the device, and two 24-volt 100-watt pumps (4) for transferring the fluid in the right half of the device.

[0011] In order to ensure optimal fluid circulation along the flow path, a suction pump may also be used at the end of the fluid circulation path. The suction pump may operate simultaneously with the conventional fluid pump or may alternatively replace it.

[0012] One hot fluid outlet (12) is provided toward the silicone hose of the left half, and one outlet (16) is provided toward the silicone hose of the right half. After being heated, the fluid exits these outlets at high speed, flows through the silicone hoses, and enters the mechanical massage components, thereby actuating the components and producing massage, after which the fluid exits from the opposite side of the massage components. The fluid then enters another silicone hose and is guided to the next mechanical massage component, and finally returns to the original reservoir through the upper inlets (11, 15). ThisEnglish Description closed-loop circulation cycle is continuously repeated. The silicone hose forms a part of the fluid transfer path.

[0013] The silicone hoses and the mechanical massage components are arranged between layers that support and retain the components. A fabric layer (33) is positioned beneath the components, and an integrated thin elastic plastic layer (34) is arranged above the components and is in contact with the user’s body. The fabric layer, which may be made of any suitable material, covers the legs and the lower back.

[0014] A silicone hose carrying hot fluid (35) is attached in a spiral configuration on the surface of the fabric layer and transfers the heat generated by the hot fluid to the muscles of the legs and the lower back through the thin elastic plastic layer. Alternatively, the routing of the silicone hoses may be dedicated exclusively to the movement of the massage components, and heat or cold transfer may be provided by means of a global bag-like covering surrounding the entire legs, such that the hot fluid is contained in the bag without circulation, while a separate path is used solely for the massage components. In this configuration, the fluid flow path is shortened and used only for actuating the massage components, and in such a case, massage motors may be used instead of mechanical massage components.

[0015] The mechanical massage units are responsible for massaging the groin area and the muscles of the legs and the lower back, and include the following:

[0016] Rotary mechanical massage unit with heat and cold transfer capability (37):

[0017] The rotary mechanical massage unit comprises a housing having a fluid inlet connected to a hose and a fluid outlet connected to another hose. A turbine (46) is arranged at the center of the housing, such that when the incoming fluid impinges on the turbine blades, the turbine is driven into rotation.

[0018] A protruding disk element (44), which is directly connected to the turbine and is outside of the housing, rotates at high speed. A plurality of rolling balls (43) are disposed within the disk element. These balls are solid, compact elements and are snap-fitted into the disk. As the disk rotates, the balls roll in a circular motion over the muscles and the groin area, thereby providing a massaging effect.English Description

[0019] A plate (37) is disposed between the housing and the disk element, separating the external environment from the fluid environment. At the center of the housing, and between the disk element and the turbine, a compressed oil seal and an O-ring (45) are provided, the function of which is to seal the fluid so that, during rotation of the turbine, the fluid does not leak out of the housing.

[0020] After the fluid impinges on and rotates the turbine, the fluid exits through the outlet of the housing, enters the hose, and is then directed to the next massage unit. A portion of the fluid remains inside the housing, thereby heating the entire housing, so that this heat, together with the heat of the hoses, is transferred to the surface of the skin.

[0021] Quantum Mechanical Massager with Heat and Cold Transfer Capability (38):

[0022] The quantum mechanical massager comprises a housing that is slightly larger than the other mechanical massagers. This massager includes two fluid inlets, wherein a first inlet (47) is configured to direct fluid for movement and impingement onto a horizontal turbine (53), and a second fluid inlet (48) is configured to direct fluid for movement and impingement onto a vertical turbine (52). Prior to entering the massager, the fluid flow is equally divided by a splitter (54) between the two inlets, such that the fluid impinges on each turbine separately, and is then discharged through a single, larger outlet. Downstream of the massager, the larger outlet gradually transitions into a smaller hose.

[0023] The horizontal turbine is provided with elastic rods having spherical ends (55):The horizontal turbine is supported on two bearing-equipped holders (51), which are attached to the upper portion of the housing, and the function of which is to support the horizontal turbine around the vertical turbine. Upon rotation of the horizontal turbine, the spherical ends of the elastic rods strike protrusions formed on the inner surface of the housing (49) at high speed, thereby generating friction and vibration in the side walls of the housing.

[0024] The vertical turbine is connected to the bottom of the housing by a support rod, in a manner similar to a wind turbine. Upon rotation of the vertical turbine, the spherical ends of its elastic rods strike obstacles provided on the bottom and the top surfaces (50) of the housing, thereby generating vibration. As a result, the twoEnglish Description turbines operate in coordination to produce a vibratory massage over the entire surface of the housing. In this massager, the horizontal turbine is larger than the vertical turbine so as to prevent contact and collision between the two turbines.

[0025] Latex-Based Mechanical Massager (39):

[0026] The latex-based mechanical massager comprises a housing incorporating a latex element and having one fluid inlet (63) and one fluid outlet (64). A hollow turbine (56) is disposed at the center of the housing. A shaft-like protrusion (59) is formed at the center of the housing and extends into the turbine to support the turbine, such that the turbine is rotatable about the axis of the protrusion. The turbine includes a plurality of rods and impact balls arranged on its outer surface. When the fluid impinges on the turbine, the turbine is driven to rotate, and the impact balls strike protrusions formed on the inner surface of the housing (60).

[0027] The massager is mounted in the device at an angle of approximately 90 degrees. The lower portion of the housing, which is in contact with the muscle surface, is formed of an elastic latex layer (61 ), to which a plastic plate (62) is attached. The latex layer and the plate are positioned directly against the muscle surface, and upon rotation of the turbine and impact of the balls against the latex layer, the impact force is transmitted through the plate beneath the latex layer to the groin and muscle regions.

[0028] Furthermore, the interior of the turbine includes a plurality of protrusions (58) and at least one free-moving ball (57). During rotation of the turbine, the free- moving ball is driven by centrifugal force and, upon colliding with the protrusions on the bottom of the turbine, loses its balance and strikes the inner wall of the turbine. The force of this impact is transmitted via the central shaft (59) to the entire housing. Accordingly, in this massager, three distinct types of vibration are generated, namely vibrations resulting from the housing protrusions, the latex layer, and the free-moving ball. This vibratory massage, together with the heat of the warm fluid accumulated within the housing, is transferred to the surface of the user’s skin.

[0029] Crank-Type Mechanical Massager (40):English Description

[0030] The crank-type mechanical massager comprises a housing provided with one fluid inlet (70) and one fluid outlet (71) and is generally similar to the latex-based massager (39). The difference lies in that a shaft (68) is disposed at the center of the turbine, and a crank (65) is mounted at the end of the shaft. Upon rotation of the turbine, in addition to striking the protrusions formed on the inner surface of the housing, the shaft and the crank are also driven to rotate. Due to the crank being positioned eccentrically relative to the shaft axis, a centrifugal force is generated during rotation, thereby producing vibration. This vibration is transmitted through the central shaft to the entire housing.

[0031] A portion of the shaft and the crank element are located outside the fluid environment. A hollow cylindrical guard (67) is mounted around the crank to protect it from unavoidable contact with the external environment. A oil seal and an O-ring (66) are arranged around the shaft and between the internal fluid environment of the housing and the external environment of the shaft to prevent leakage of the fluid.

[0032] On the outer surface of the housings of some mechanical massagers, including the crank-type massager, protrusions (69) are formed, which massage the surface of the user’s leg during vibration of the housing.

[0033] Two-Piece (Front-Back) Mechanical Massager (42):

[0034] The two-piece mechanical massager comprises two housings that are fixedly joined together. One housing contains only the turbine (72), while the rear housing contains friction-generating components (73). The friction-generating components and the turbine are interconnected through the center of the two housings, such that rotation of the turbine causes the friction-generating components to move correspondingly. However, the fluid flows only within the housing that contains the turbine, and no fluid is present in the friction-generating housing. The interface between the two housings is sealed by a compressed oil seal and an O-ring, thereby preventing the fluid from entering the frictiongenerating housing.English Description

[0035] In this massager, the friction-generating housing employs impact balls, a free- moving ball, a shaft, and a crank to generate vibration and massage, the functions of each of which have been described in the previous massagers.

[0036] The turbine housing includes two inlets and two outlets. A first inlet (74), located at the upper side, directs the fluid toward the turbine blades, and the fluid exits through the outlet positioned opposite thereto. A second inlet (75), located at the lower side, also directs the fluid toward the turbine, with the fluid exiting through the corresponding opposite outlet. Overall, the rotational force generated by the turbine-containing housing causes the friction-generating housing to produce vibration and massage. In this configuration, the silicone hoses and the fluid flow pass through the housing twice.

[0037] In all components of the device where there is a possibility of fluid leakage to the exterior of the housing, compressed oil seals and O-rings are used to provide leak-proof sealing.

[0038] After passing through all of the mechanical massagers, the heated fluid returns to the reservoir from the front portion of the seat back and from behind the athlete’s lower back, as indicated in the drawings by reference numerals (19, 20). Hose (19) descends from the left half of the device, and another hose (20) descends from the right half of the device. Prior to returning to the reservoir, the fluid passes through two mechanical massagers (41) that are provided for massaging the lower back, such that the lower back is also massaged simultaneously with the application of heat.

[0039] For cold transfer, an 8-liter fluid reservoir (2), which is positioned below the heated fluid reservoir and behind the seat back, is used. This reservoir includes a fluid inlet for filling the reservoir (10) and a fluid cooling element (7) for cooling the fluid. Similar to the heated fluid reservoir, two 24-volt, 100-watt pumps (5) are used to transfer the cold fluid to the left half of the device, and two additional 24- volt, 100-watt pumps (6) are used to transfer the cold fluid to the right half of the device. The heated and cold fluid reservoirs may have different capacities depending on requirements such as the size of the device, the length of the fluid path, the number of massagers, and other design parameters.English Description

[0040] After being cooled, the fluid exits the cold fluid reservoir through outlets (14, 18) and enters the cold-fluid silicone hose (36). By flowing along spiral paths, the cold is transferred to the legs, and after the heat exchange, the fluid returns to the fluid reservoir through inlets (13, 17). This cycle continues as a closed liquid circulation loop. A unified thin gelatinous layer (34) is disposed over all massage components and hoses, through which heat, cold, and massage effects are transmitted to the muscles.

[0041] Below the seat (28), a control box (23), a traction motor (22), and traction levers (21) are arranged. The traction motor drives the levers connected to the leg holders (29, 76) to move back and forth, thereby opening and closing the legs positioned on the leg holders.

[0042] Adjacent to the traction motor, an ammeter is provided to measure the force applied to the legs. A laser angle sensor (24) is installed at the front of the control box; by projecting a laser beam onto a facing plate (25), it digitally displays the leg opening angle on a display (27).

[0043] The plate facing the laser angle sensor is made of aluminum and is mounted on the right leg holding rod. An analog angle sensor (26) is also positioned beside the laser angle sensor and indicates the angle via the tightening or loosening of a cord connected to a pointer. The leg holders are arranged in a two-layer configuration, wherein the upper leg holder (31) is provided for vertical movement of the legs and the posterior groin region in an up-and-down direction. Beneath each upper leg holder, a lifting jack (30, 32) is connected to a lower leg holder; upon extension of the lifting jack, the upper leg holder is raised and opened. The upper leg holder and the lifting jack are used for stretching the posterior groin muscles.

[0044] A display is positioned in front of the seat, through which all device commands are controlled via a touch interface, including control of the fluid temperature, massage speed, and synchronization of the music playback rhythm with the massage rhythm. In such a manner, during music playback from the display, as the music reaches its peaks, the input voltage increases and the fluid transfer rate by the pumps is increased. Consequently, the massage speed and vibration intensity are increased. Conversely, when the bass and beat of the musicioEnglish Description decrease, the fluid transfer rate of the pumps is reduced, resulting in a corresponding decrease in massage speed. This operation contributes to the stimulation of endorphin secretion (the “happiness hormone”) in the user’s body. The power of the pumps may vary depending on the number of massage zones, such that a higher number of zones requires pumps with greater power.

[0045] In this device, when cold massage is required, the silicone hoses supplying the massage units can be disconnected from the hot fluid source and connected to the cold fluid source, thereby switching the operating mode. Ultimately, the device is capable of massaging the legs during stretching using hot fluid only, a combination of hot and cold fluids (contrast therapy), or cold fluid only, thereby assisting leg flexibility. Cold application is also used to stabilize the achieved flexibility and to relieve pain.

[0046] The result of this method is a reduction of lactic acid in the muscles, an increase in blood flow at painful muscle regions, enhanced oxygen delivery, and stimulation of endorphin secretion in the brain, ultimately leading to muscle relaxation at the moment of leg stretching and flexibility. The exact installation location of each heat- and cold-transferring massage unit may be arranged according to the anatomical position of the leg muscles and groin areas.

[0047] Furthermore, instead of an electric traction motor in the control box, a mechanical water-driven motor may be used, such that the fluid, after completing the massage and temperature transfer stages to the body, enters the control box before returning to the fluid reservoir and drives a mechanical motor comprising a gear coupled to two water turbines rotating in opposite directions. By rotation of the gear and associated components of the control box, the leg holders are mechanically opened or closed, after which the fluid enters the fluid reservoir and the cycle continues.Advantageous Effects of Invention

[0048] The advantages provided by the present device include the following:a. Opening and stretching of the legs with the minimum possible pain due to relaxation of the muscles during stretching.b. Prevention of injury and strain to the groin muscles during leg stretching.English Description c. Time efficiency for athletes who wish to open their legs to the desired and achievable extent.d. No requirement for electric massage motors.e. Utilization of fluid-driven motive force to actuate the massage units. f. Use of fluid-based heating and cooling instead of covering the leg surfaces with heating elements.g. Stabilization of leg flexibility through cooling after thermal stretching. h. Lower manufacturing cost of the mechanical massage units compared to wound electric massage motors.i. Long service life of the massage units due to their non-electrical nature and resistance to failure caused by exposure to heated fluid. Brief Description of Drawings

[0061] In Figure 2, the device is illustrated without the elastic plastic layer so that the internal components of the device are visible. In the right half of the device, element (34) is shown with the elastic plastic layer, a fabric layer, or any other type of covering that is capable of thermal exchange and transmission of kinetic force; in this portion, the components located beneath the layer are not visible.ExamplesEnglish Description

[0062] After sitting on the seat, the athlete places his or her legs inside the fabric- gelatinous cover and wraps the cover around the legs. Upon activation of the device, the heated fluid enters the silicone hoses and, by passing through the mechanical massage units, simultaneously initiates heating and massage.

[0063] After heat transfer and massage, the leg muscles become softened. The system then enters the stretching phase, during which music is played and the massage rhythm is synchronized with the music rhythm, thereby stimulating the release of endorphins. Subsequently, based on the pressure applied to the legs, the user commands the opening of the legs from a minimum of one degree via the device display.

[0064] During this process, as the fluid cools, the second cold-fluid reservoir is activated and the cold fluid circulates through the silicone hoses. This cooling may be applied together with heating in the form of contrast therapy, or solely as a cooling phase without heating, in order to relieve pain and inflammation and to stabilize the groin muscles after heating and stretching. After the legs are opened by means of the motor located beneath the seat and the control box, the laser angle sensor displays the leg opening angle digitally on the display, while the analog angle sensor provides an analog indication.

[0065] By allowing adjustment of mechanical and control parameters, the system enables safe use for a wide range of users, from children — who cannot manage pain in the same manner as adults — to professional athletes.Industrial Applicability

[0066] The device is applicable in the sports equipment industry across a wide range of sports disciplines, including gymnastics, martial arts, yoga, wrestling, ballet, and all activities in which leg flexibility is required.
