The present invention relates to a pelvis remedial seated device for remedying into its original place a women's widened pelvis after child birth. More particularly, the invention relates to a pelvis remedial seated device and a control method thereof wherein the air pressure can artificially press the pelvis portion of the woman while seated or lying down relaxedly without constraining the human body so that the woman can get into good shape as soon as it possible.
As a woman grows older, the muscle of her pelvis is gradually weakened with cause of sexual life and child delivery. After the birth, particularly the pelvis muscle, which supports hypogastrium, the bladder, the vagina and the anus, takes a sudden turn for worse.
The typical actual phenomena of the physical process occurred by following is that the pelvis gets wider. With the widened pelvis, the body of the woman loses a balance and it will not be able to maintain a good shape.
Additionally, as the pelvis muscle weakens, the function that controls the bladder decreases. Even when the bladder is full, urinary incontinence can result in spite of oneself.
Another phenomena occurred by pelvis base muscular weakening is that the controllability of the sphincter, which contracts and dilates the vagina and the anus notedly decreases, thus bring an impediment to a married life.
In many conventional arts, a guard belt having a form of a band is disclosed, which is worn on a waist or pelvis portion to support a weaken pelvis muscle. The typical prior technology describing the guard belt is cited in Korean Utility Patent No. 20-0166329.
The conventional guard belt is comprised of an inner band having a plurality of steel balls therein and an outer band covering the inner belt. It anticipates an action and effect such that a press of steel balls supports the articular ligament of the lumbar vertebra.
However, since conventional guard belts described above are worn using a Velcro (an adhesive tape which is substituted for a button: trademark) fastener attached on each free end of the belt, wearing the guard belt cause localized pressure in the human body and induces a pain. It also brings about a hindrance in activity of the body.
Further, as a wearer is doing an action, the tightening force gradually becomes loose and it must be tightened frequently, which brings a cumbersome problem. Furthermore, the inconvenience is brought that the wearer on a pelvis portion could not sit and lie down relaxedly.
Particularly, the conventional belt with its form of band has a weak pressure force and therefore not much effect can be anticipated. When a pelvis is crooked, it has a disadvantage that no appropriate remedy can be achieved.
Accordingly, the present invention has been made with taking the above problems occurring in the prior art into consideration, and an object of the present invention is to provide a pelvis remedial seated device and a control method thereof in which the air pressure can smoothly press the pelvis portion of a woman while seated or lying down relaxedly, with good usability and moderation to the human body, and also a widened pelvis of woman after the birth is returned into its original place so as to maintain a good shape, and further the feminine function decrease and the disease caused by the widened pelvis can effectively be cured.
Another object of the present invention is to provide a pelvis remedial seated device and a control method thereof in which air pressure supplied to respective air bags can be regulated according to human's contour, and the pelvis can be pressed in a predetermined level irrespective of human's contour.
Another object of the present invention is to provide a pelvis remedial seated device and a control method thereof in which front and rear air bags installed at each right and left side can be expanded or contracted crosswise, and a crooked pelvis can be remedied by applying pressure to the pelvis diagonally.
Another object of the present invention is to provide a pelvis remedial seated device and a control method thereof in which air pressure can be applied in various levels and the pelvis can be remedied using various modes such as massage, fumble with pressing, and beat.
In order to accomplish the above object, a pelvis remedial seated device comprises a seat included a seat cushion on which an occupant is to be seated and a left/right seat side provided uprightly at each side end of the seat cushion; a pair of air bags nested on an inner side of each side for enabling themselves to be expanded or contracted by air supplied into or discharged from the inside of the air bag; and air injection means for providing air pressure to the air bags; wherein the expanding air pressure in the air bags presses the pelvis portion of an occupant.

The above and other objects, features and other advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings, in which:
This invention will be described in further detail by way of exemplary embodiments with reference to the accompanying drawings.
As shown in
The seat 10 has a seat cushion 11 on which an occupant is to be seated and right/left seat sides 112a, 12b provided uprightly at each side end of the seat cushion 11. The right/left seat sides 12a, 12b maintain the expanding pressure of the air bags 20a, 20b as an occupant's pelvis portion is pressed by the expanded air bags 20a, 20b.
The seat cushion 11 and the right/left seat sides 12a, 12b, as shown in
In the inner space of the seat 10, components of an air injection means, a photo detective sensor 39, a far-infrared generator “T”, and an oscillating motor “M” which are described hereafter are accommodated.
The photo detective sensor 39, as illustrated in
The far-infrared generator “T”, as shown in
The oscillating motor “M” and the far-infrared generator “T”, as shown in
In
A first seat back 17 is demountably provided at the rear of the right/left seat side 12a, 12b (
In the seat cushion 11, a concaved groove (
At the central portion of the right/left seat sides 12a, 12b, as shown in
A flexible fabric 18 is installed round the edge of the right/left seat sides 12a, 12b to place the air bags 20a, 20b in their position. The flexible fabric 18 is expanded or contracted owing to the operation of the air bags 20a, 20b nested between the flexible fabric 18 and the inner side of the right/left seat sides 12a, 12b. Along the exterior of the right/left seat sides 12a, 12b, a rim cover 19 is provided to shield a fringe of the flexible fabric 18.
A pair of air bags 20a, 20b installed in the right/left seat sides 12a, 12b receive the air from the air injection means to be expanded, or release the air from the air bags to be contracted, thus give a pressure to a pelvis. High strength vinyl bag can be employed as the air bag. A portion of the seat sides corresponding to an occupant's pelvis is independently divided into a front/rear cells 22a, 22b, 23a, 23b.
In this invention, a plural of rubber pads 40 are further provided at the exterior of the right/left air bags 20a, 20b. The rubber pads 40 will be used to properly adjust the pressure against the femoral region depending on an occupant's contour. For instance, a woman who has a smaller pelvis than normal size can employ plural rubber pads to increase the pressure to her femoral region.
Further, this invention provides a chair 50 on which the seat 10 is placed that can be used as a usual chair. The chair 50, as shown in 5, is comprised of a support plate 51 on which the rim of the seat cushion 11 is tightly nested, a second seat back 52 provided uprightly at the rear portion of the support plate 51 and legs 53 extended down from the support plate 51. The chair can be adapted as shown in
In this embodiment, the seat cushion 11 and the right/left seat sides 12a, 12b are detached from each other, and a rail 61 is transversely installed at the central bottom of the seat cushion 11. At each end of the rail 61 is provided in a transversal movement a pair of angular connector 62 which is fixed to the right/left seat sides 12a, 12b. Legs 66 are installed at the central bottom of the rail 61. Plural jaws 63 are formed at the bottom of the angular connector 62 in an even interval. Further, at longitudinal slot (not shown) are installed a pair of stoppers which can be pressed by a spring 64. Therefore, the width between the right/left seat side 12a, 12b can be adjusted to fit an occupant's physical size, and the stopper 65 restricts the jaws 63 so as not to move the right/left seat sides 12a, 12b.
With this contribution, the air supplied from the right/left air pumps 31a, 31b is injected into the right/left directional valves 32a, 32b. Since left air pressure sensor 38b is installed between the left air pump 31b and the left directional valve 32b, the air pressure supplied into the left control valve 32b from the left air pump 31b can be detected and the signal value of the detected air pressure is sent to the controller 35. Similarly, since the right air pressure sensor 38a is installed between the right air pump 31a and the right directional valve 32a, the air pressure supplied into the right control valve 32a from the right air pump 31a can be detected and the signal value of the detected air pressure is sent to the controller 35.
The controller 35′ receives the signal of air pressure detected by the air pressure sensors 38a, 38b and compares it with a pressure level which is inputted through the control panel by an occupant. After a comparison, if the detected pressure value is larger than a predetermined set value, the operation of the air pumps 31a, 31b is stopped and no more air is injected into the air bags 20a, 20b.
Under a command of the controller 35, the right/left direction control valves 32a, 32b supplies or relieves the air into/from the front/rear cell 22b, 23b of the left air bag 20b and the front/rear cells 22a, 23a of the right air bag 20a.
When the left direction control valve 32b supplies the air into the front cell 22b of the left air bag 20b, the front cell of the left air bag 20b is expanded to apply a press to the left front portion of a pelvis. Similarly, when the left direction control valve 32b supplies the air into the rear cell 23b of the left air bag 20b, the rear cell of the left air bag 20b is expanded to apply a press to the left rear portion of a pelvis.
The operation of the left side as explained above will be adapted to the right direction control valve 32a and the right air bag 20a of the right side. Therefore, with the control of the left direction control valve 32b, the air can supply either front cell 22b or rear cell 23b of the left air bag 20b selectively; in the same manner, with the control of the right direction control valve 32a, the air can supply either front cell 22a or rear cell 23a of the right air bag 20a selectively.
To enable the remedial device to be operated as massage function, as shown in
The level of air pressure supplied into the right/left air bags 20a, 20b categorizes into three such as “high”, “medium” and “low” by the control of level key pads provided on the control panel 37. For instance, “high” can be set to 290±10 mmHg, “medium” can be set to 230±10 mmHg and “low” can be set to 140±10 mmHg. Even when the air discharge from the air bags 20a, 20b, the value of pressure dose not need to be set to “0”, and “high” may be set to 180±10 mmHg, “medium” may be set to 150±10 mmHg and “low” may be set to 90±10 mmHg. Therefore, the value of pressure can be maintained to support a pelvis of an occupant even when the air is discharged from the air bags 20a, 20b.
In the inventive remedial device, as the operation of the right/left direction valves 32a, 32b and the front/rear discharge valves 33a, 33b, 34a, 34b can be made a combination and many modes, such as front press, rear press, front/rear simultaneous press, front/rear crossing press, and expansion/contraction repeating press, etc. can be performed.
The far-infrared generator “T”, the low frequency oscillator “T” and an oscillating motor “M” are installed at the bottom of the seat cushion 11 as explained above. The operation of these devices can combine with the working of the air bags 20a, 20b to achieve pelvis remedy in various modes. For example, the ‘fumble with pressing’ effect can be attained at the low frequency oscillator “F” with ‘fumble with pressing’ mode, and at the same time, all portion of pelvis can be massaged by the repeated press and release using the front/rear cells 22a, 22b, 23a, 23b.
The display panel 36 is comprised of a timer unit 36a indicating the running duration of the remedial device, a level indicating unit 36b for displaying the level of a chosen function and a function indicating unit 36c for displaying which function an occupant choose.
The control panel 37 is comprised of plural function key pads 37a for selecting an adaptable function such as “massage”, “beat”, and “fumble with pressing”, a pair of level key pads 37b for setting the level of a function chosen, plural mode key pads 37c for choosing various mode, a time set key pad 37d for setting a running duration of the chosen function or the mode and a power key pad 37e for turning on/off power.
An occupant pushes the power key pad to apply the power to the device, and a default set time is displayed on the timer unit 36a, and also a value of a level chosen previously is shown on the level indicating unit 36b. When an occupant presses the “masage” key among the function key pads 37a, a signal corresponding to “massage” function is sent to the controller 35 from the control panel 37.
Under a command of the controller 35, a character “massage” is shown on the function indicating unit 36c, and a default time is displayed on the timer unit 36a, and the level of the chosen function is presented on the level indicating unit 36b. With a command of the controller 35, the right/left air pumps 31a, 31b supply the air into the front/rear cells 22a, 22b, 23a, 23b of the right/left air bags 20a, 20b. The air pressure supplied to the cells can be adjusted by the level key pads 37b.
The air pressure supplied to the cells 22a, 22b, 23a, 23b of the air bags 20a, 20b is established as 10 levels between 50˜500 mmHg, and each level value has 50 mmHg. That is, first level corresponds to 50 mmHg, and second level corresponds to 100 mmHg, third level corresponds to 150 mmHg, . . . , and tenth level corresponds to 500 mmHg.
An occupant can select one function, such as “massage”, or “beat”, or “fumble with pressing” among the function key pads 37a. During running of the device, however, if a weakening air pressure is felt, an occupant presses a “t” key pad of, indicating an ascend of an air pressure, the level key pads 37b, and an air pressure having one level higher than a present pressure value is supplied to the cells of the air bags 20a, 20b. While still pressing the “T” key pad, the level increases up to the tenth level, in which the time between each one level increase can be set at 5 seconds.
A state of air pressure value is displayed on the level indicating unit 36b. In this embodiment, if the chosen value of air pressure is 150 mmHg, three bars are shown on the level indicating unit 36b. When pressing the “↑” key pad to increase one level, the four bars are shown on the level indicating unit 36b. Similarly, a descent “↓” key pad is pressed one time and one level is decreased. While still pressing the “↓” key pad, each bar is eliminated per 5 seconds, finally one level is arrived.
After an occupant selects the function by pressing on one key among the function key pads 37a, a running duration is selected by pressing the time set key pad 37d. When choosing the function for the first time, for example, “0” is displayed on the timer unit 36a. A value corresponding to 1 minute is shown on the timer unit 36a as the timer set key pad 37d is pressed one time. One minute is added to the existed value in proportion to press count of the time set key pad 37d. While still pressing the time set key pad 37d, the displaying value increases up in a predetermined speed (e.g. 1 minute per 1 second).
Further, with the mode key pads 37c, four modes can be chosen, in which a combination of “massage”, “beat”, “fumble with pressing” can be accomplished in constant pattern. If “M1” is a mode repeating “massage”, “beat”, “fumble with pressing”, when an occupant presses “M1”, the front/rear cells 22a, 22b, 23a, 23b are expanded or contracted repeatedly in a constant pattern, thus achieving a repeating function of “massage”, “beat”, “fumble with pressing”.
At time t1, under a command of the controller 35, since the right/left direction valves 32a, 32b opens its rear path, and closes its front path, the air is supplied to the rear cells 23a, 23b. Since the right/left front air discharge valves 33a, 33b maintain its closed state, and the right/left rear air discharge valves 34a, 34b are closed, the front/rear cells 22a, 22b, 23a, 23b are expanded, thus pressing the front/rear portion of the pelvis.
At time t2, in the right/left directional valves 32a, 32b, its rear path is still opened, and its front path is continually closed, and thus the air is still supplied to the rear cells 23a, 23b. Since the front air discharge valves 33a, 33b are opened, the air is discharged from the right/front cell 22a. With the state of the pressure release against the front portion of a pelvis, the rear air discharge valves 34a, 34b are still closed and the rear cells 23a, 23b maintain its expansion state, thus pressing the rear portion of the pelvis.
At time t3, the right/left directional valves 32a, 32b supply the air to the rear cells 23a, 23b still, and since the front air discharge valves 33a, 33b are being opened, but the front path is still closed, the air is not supplied to the front cells 22a, 22b, thus no pressing is applied to the front portion of the pelvis. Since the rear air discharge valve is still closed, the rear cells 23a, 23b maintain its expansion state, thus continuing the pressing to the rear portion of the pelvis.
At time t4, under a command of the controller 35, since the right/left directional valves 32a, 32b open its front path to supply the air to the front cells 22a, 22b, and close its rear path, the air is not supplied to the rear cells 23a, 23b. Since the front air discharge valves 33a, 33b as well as the rear air discharge valves 34a, 34b maintain their closed state, the front cells 22a, 22b stay in the air supply state, and the rear cells 23a, 23b are expanded, thus pressing the front/rear portion of the pelvis.
At time t5, under a command of the controller 35, the right/left directional valves 32a, 32b still open its front path, but no power is applied to the air pumps 31a, 31b, and the air is not supplied to the front cells 22a, 22b. Also, since the rear path is closed, no air is supplied to the rear cells 23a, 23b. At this time, the front/rear air discharge valves are still closed, and the front/rear cells 22a, 22b, 23a, 23b maintain their expansion state, thus pressing continuously the front/rear portion of the pelvis.
At time t6, the air pumps 31a, 31b and the right/left directional valves 32a, 32b maintain their previous state, but the front/rear air discharge valves 33a, 33b, 34a, 34b are opened, and the air is discharged from each front/rear cell 22a, 22b, 23a, 23b, thus releasing the pressing against the pelvis.
The air pressure of the air bags 20a, 20b is detected by the air pressure sensors 38a, 38b, and the controller determines whether the detected air pressure is lower than a value set by an occupant, and if it is, returns to step S42. If it is not, goes to next step S45 (step S44). At step S45, a running of the air pumps 31a, 31b is stopped for predetermined period (e.g. 10 seconds) and the air pressure of the air bags 20a, 20b can be maintained as the setting value. At step S46, the front/rear air discharge valves 33a, 33b, 34a, 34b are opened and the air is discharged until the air pressure of the air bags 20a, 20b is lower than a discharge pressure.
At step S47, the controller determines whether the air pressure of the air bags 20a, 20b is lower than a discharge pressure, if it is not, returns to step S46. If it is, goes to next step S48. At step S48, the running of the air pumps 31a, 31b is stopped for predetermined period (e.g. 10 seconds). At step S49, the controller compares the present time elapsed from step S41 with the predetermined set time (e.g. 15 minutes). If the present time has not, returns to step S42. If it has, goes to stop step where the execution of e program is terminated.
As above, the injection and discharge operation into/from the front/rear cells 22a, 22b, 23a, 23b is repeated, thus attaining the effect of pelvis's massage.
When a pelvis is crooked, to remedy the crooked pelvis, a left/front portion and a right/rear portion of a pelvis are pressed, otherwise a right/rear portion and a left/front portion of a pelvis are pressed in opposite to the crooked direction. For example, when right portion of a pelvis is crooked backward and left portion of a pelvis is crooked forward, as shown in
The air pressure of the air bags 20a, 20b is detected by the air pressure sensors 38a, 38b, and the controller determines whether the detected air pressure is lower than a value set by an occupant; if it is, returns to step S62. If it is not, goes to next step S65 (step S64). At step S65, the controller determines whether a type of crookedness remedy is a right crookedness remedy or a left crook remedy. If it is the left remedy, the left/rear air discharge valve 34b and the right/front air discharge valve 33a are operated, and the air is discharged until the air pressure of the left/rear cell 23b and the right/front cell 22a is the appropriated one to support an occupant's pelvis (step S66). At step S67, the controller determines whether the air pressure of the left/rear cell 23b and the right/front cell 22a is lower than a discharge pressure, if it is not, returns to step S66. If it is, goes to next step S68. At step S68, a running of the air pumps 31a, 31b is stopped for predetermined period (e.g. 10 seconds). At step S69, the controller compares the present time elapsed from step S61 with the predetermined time (e.g. 15 minutes). If the present time has not, returns to step S62. If it has, goes to stop step where the execution of the program is terminated.
Meanwhile, at step S65, if the determination is a left crookedness remedy, the left/front air discharge valve 33b and the right/rear air discharge valve 34a are operated, and the air is discharged until the air pressure of the left/front cell 22b and the right/rear cell 23a is the appropriated one to support an occupant's pelvis (step S70). At step S71, the controller determines whether the air pressure of the left/front cell 22b and the right/rear cell 23a is lower than a discharge pressure, if it is not, returns to step S70. If it is, goes to step S68 and follows the process.
Therefore, the air is supplied to the front cell 22b of the left air bag 20b and the rear cell 23a of the right air bag 20a, and the air pressure corresponding to a selected level is applied. At the same time, the air is discharged from the front cell 23b of the rear air bag 20b and the front cell 22a of the right air bag 20a Thus, the left pelvis is pressed backward and the right pelvis is pressed forward. As the result, the left forward crooked pelvis is pushed in a right forward direction, thus attaining the straightening effect.
Similarly, the air is supplied to the rear cell 23b of the left air bag 20b and the front cell 22a of the right air bag 20a, and the air pressure corresponding to a selected level is applied. At the same time, the air is discharged from the front cell 22b of the left air bag 20b and the rear cell 23a of the right air bag 20a Thus, the right pelvis is pressed backward and the left pelvis is pressed forward. As the result, the right forward crooked pelvis is pushed in a left forward direction, thus attaining the straightening effect.
As the present invention is comprised of as above, it is very useful to contract the widened pelvis by pressing a woman's pelvis and curing the crooked pelvis. The widening of a pelvis caused by sexual life and birth can be cured to go back to an original condition such as a woman's pelvis in her twenties.
According to the inventive pelvis remedial seated device and a control method thereof described above, the air pressure can be controlled as one's pleasures with seating or lying down relaxedly and the pelvis portion of a woman can be pressed smoothly in a continuous and repeated manner, which leads to good usability and moderation to the human body. Also, a widened pelvis of woman after the birth is returned to its original place so as to maintain a good shape as soon as it can.
Further, the present invention has an effect in that the pressure can be applied by the expansion and contraction of air bags, and various mode such as massage, beat and fumble with pressing can be selected, thus achieving the pelvis remedy promptly.
Further, the present invention has an effect in that when the detected pressure level of air bags become the predetermined level set by user, the air supply can be stopped, thus pressing the human irrespective of human's contour in a predetermined pressure level.
Further, the present invention has an effect in that a front or a rear cell of air bags provided at each right or left side can be expanded or contracted crosswise, and in the case of a crooked pelvis, the pressure can be applied in the opposite direction against the crookedness direction, thus enabling the crooked pelvis to be cured.
Additionally, the present invention has various practical uses for human's body remedy in that a knee of user can be put on a seat bottom and can be pressed, thus utilizing the remedy of splayed legs in a form of “O”.
The prevent invention as above is the useful invention in which the feminine function decreases and the disease caused by the widened pelvis can effectively be cured.
