Description

  According to the present invention, the subject is located in the buttock accommodation space, and can use the subject's weight and body movement to press and stretch the pressure points and muscles around the hip joint, which is excessive due to prolonged use. The present invention relates to a lumbar buttock press expander having a mechanism that can be switched and used as needed and not needed to eliminate pain caused by stimulation.

  It is the theory that back pain and pain which are common in daily life, which are said to be back pain, are caused by fatigue of the muscles, the strength of muscles that support the waist decreases, blood circulation worsens, and muscle tension increases. And, in order to prevent discomfort and pain in the lower back, or when there is discomfort and pain in the lower back, it is effective to apply pressure to the pressure points and muscles around the sciatic area and around the connection between the buttocks and the thighs. There is a theory, using the weight of the subject's upper body when the subject sits down and the natural movement of the subject to move the body unconsciously, automatically the pressure points and muscles around the connection area of the subject's hips and hips and thighs There is an automatic back massager that understands and understands. (See Patent Document 1)

There is a theory that when you sit in a chair for a long time, the muscles that support the lower back get tired and back pain occurs. And when there is discomfort or pain in the lower back, it is said that it is effective to use a weight of the lower body of the subject to stretch the waist or to remove the gravity of the upper body of the subject. There is a health device that supports the upper body and lifts the waist to remove the gravity of the upper body that is applied to the lumbar area, and the lower body weight extends and relaxes the muscles of the lumbar area. (See Patent Document 2)

  It is the theory that back pain and pain which are common in daily life, which are said to be back pain, are caused by fatigue of the muscles, the strength of muscles that support the waist decreases, blood circulation worsens, and muscle tension increases. The subject sits in contact with the subject's support member with muscles around the buttocks and thighs connection portion, supports the upper body with a backrest member, and the buttocks and thighs connection portion by the subject's weight and body movement When using an automatic lumbar massage device (see Patent Document 1), which presses and extends surrounding muscles and dissolves, it is a problem that the stimulation becomes excessive and the site in contact with the subject support member becomes tense and painful when used for a long time There is.

  The automatic waist massager is a mechanism for loading the weight of the subject on the subject support member and disassembling the muscles around the connecting part of the hip and thigh. However, there is a problem that there is no mechanism for adjusting the weight of the subject who is loaded on the subject support member, and there is the inconvenience that it can not be used according to the subject's physical condition, body shape, preference.

  If you want to prevent lumbar discomfort or pain, or if there is discomfort or pain in the lumbar region, use the weight of the subject's lower body to pull and stretch the waist, or remove the subject's upper body gravity There is a health device that supports the upper body of the subject and lifts the lower back to remove the upper body gravity applied to the lower back and extends the lower back muscles to stretch the lower back muscles (see Patent Document 2). . There is an elbow-like upper body support that supports the subject's torso, and a seat that supports the test subject's knees at the front end, with the rear end on the backrest side being displaced downward. The chair is a chair-type health appliance that lifts the waist of the subject in the air with the front end of the seat portion at the fulcrum and lifts the waist from gravity, and can extend the spine with the weight of the pelvis. The upper body is supported by the upper body support portion that supports the upper body of the subject from below, and the structure that floats the lower back in the air is such that the upper body is fixed and the movement is restrained. Therefore, when you want to use it as a health device, you have to stop your hands while working or working. If you try it, you can not use time effectively. There is a problem that a dedicated time to understand and understand the muscles is required. further,

  The upper body support supports the upper body of the subject from below to support the upper body and lower back of the subject, and supports the upper body with the upper body support section for supporting the upper body of the subject from below. The structure needs to be supported by rolling in the torso, which is a large-scale structure, so all of this structure is used for benches and chairs used in hospitals and public facilities that are required to be small and compact. Alternatively, there is a problem that it is difficult to configure using a part.

  When the subject sits on a chair, the position of the bones on the left and right of the pelvis that touch the seat surface is called a sessile point. There is a theory that weight is loaded on the seat surface in contact with the seat surface of the chair, and the repulsive force generated on the seat surface is loaded on the waist, causing pain in the waist. There are chairs and cushions with various low back pain measures that control the subject's posture to reduce or disperse this repulsive force, but it can not eliminate the repulsive force, so if you sit for a long time, your back will hurt There is a problem called.

  It is the theory that back pain and pain which are common in daily life, which are said to be back pain, are caused by fatigue of the muscles, the strength of muscles that support the waist decreases, blood circulation worsens, and muscle tension increases. For example, when sitting on a chair, if the posture is broken and your back is rounded, your body's center of gravity will shift backward. The body unconsciously pushes the lumbar spine forward in an attempt to stabilize balance. In this condition, the lower back muscles are contracted and the lower back muscles are overloaded, which makes it easy for fatigue to accumulate and cause lower back pain. When sitting on a chair in this way, there is a problem that a part of the muscles that support the lower back is stressed in order to maintain the posture, and the muscles in that part become tired and cause discomfort and pain.

  When sitting on a chair, the seat bone is slippery on the seating surface, which is a major cause of disfigurement when sitting on a chair. When the ischial point slips on the seat surface, the body tries to stabilize the balance, and a part of the muscle is overloaded, and this muscle is fatigued to cause discomfort and pain.

  Ergonomically developed chair that corrects the subject's posture to the correct posture where the pelvis stands and the spine maintains a gentle S-shaped physiological curvature, pressing the subject's correct posture further Maintain posture and force you to sit. However, a human being is an animal that wants to move at all times, and it is mental stress for the subject to be forced to take the same posture for a long time even if it is the correct posture, and it is a burden on muscles that support the waist to maintain the posture. The muscles in this part become fatigued and physical stress. In other words, there is a problem that it will be painful mentally and physically to continue this for a long time, even with the correct posture.

  A lumbar buttock press expander characterized by having a main seat and an auxiliary seat, wherein the auxiliary seat is rotatable back and forth in the direction of the subject.

  The main seat and the auxiliary seat are provided, and the auxiliary seat is rotated back and forth toward the subject to position the subject, and the hip support is suspended to form a buttock accommodation space capable of being supported. Lumbar buttock press expander as described.

  The main seat and the auxiliary seat are provided, and the auxiliary seat is rotated back and forth toward the subject, and the subject is positioned to form a pressing top surface capable of pressing and extending the pressure points and muscles around the hip joint. The lumbar buttock press expander according to 1.

  There is a main seat and an auxiliary seat, the auxiliary seat rotates back and forth toward the subject, adjusts the rotation angle of the auxiliary seat, adjusts the tilting angle of the auxiliary seat, and presses the pressure point or muscle on the pressing top surface The lumbar buttocks press and stretcher according to claim 1, wherein the lumbar buttocks and presser are adjustable.

  The present invention is a seat surface consisting of a main seat and an auxiliary seat, which can be used for a long time since the auxiliary seat can be rotated to form the pressing top surface, the subject support portion and the buttock accommodation space. When the stimulation becomes excessive, the auxiliary seat is rotated again to eliminate the pressing top surface, the subject support portion and the buttock accommodation space portion, and the stimulation can be eliminated.

  The present invention is a seat surface including a main seat and a secondary seat, and the secondary seat is rotated to adjust the height of the pressing top surface and the inclination angle of the subject support portion, thereby There is an effect that the pressing force of the pressure point and the muscle can be adjusted, and the subject can be used with a preferable pressing force.

  According to the present invention, when the subject places the ischial point in the buttocks accommodation space portion and places the upper body in the backrest, the pelvis is suspended by being supported by the pressing top surface, the subject support portion, and the backrest. It can be held, floating the lumbar in the air. In addition, there is an effect that the waist can be floated in the air even without a special structure for fixing the upper body to the back.

  The subject can move his hands and feet freely without being restrained. If you try it, you have the effect of being able to use it while doing work and working.

(1) There is a theory that when the subject's ischial point is in contact with the seat surface of the chair, the weight is loaded, the repulsive force generated on the seat surface is loaded on the waist, and the back becomes hurt. When the pelvis hangs up, the sciatic point floats. Since the repulsive force does not occur if the ischial point does not abut on the seat surface, there is an effect that the back does not hurt.
(2) When the subject positions the ischial point in the buttocks accommodation space, the pelvis hangs down and the pressing top surface abuts against the ischium. The pelvis is erected when the ischium is pushed back to the subject on the pressing top surface, and when the pelvis stands up, there is an effect that the back muscles extend naturally and a physiological S-shaped curve is formed naturally.
(3) When the subject positions the ischial point in the buttocks accommodation space, the pelvis hangs down and the ischium abuts on the pressing top surface. The weight of the subject is loaded, and the pressure points and muscles around the connection between the front and back bones and between the buttocks and thighs are pressed. Furthermore, when the subject moves his / her body, the upper body of the subject becomes a forceps with a backrest as a fulcrum, and when the pelvis is pushed forward by the action of the forceps, a pressure point around the connection between the anterior sciatic region and the hip and thigh And muscles have the effect of being crawled and stretched.
(4) When the subject places the ischial point in the buttocks accommodation space, the pelvis is suspended and held when the upper body is held against the backrest. There is an effect that the pelvis becomes heavy and the muscles around the hip joint are pulled downward by the weight and extended.
(5) When the subject places the ischial point in the buttocks accommodation space, and the upper body is held against the backrest, the pelvis is suspended and held. When the pelvis is suspended and floated, the muscles around the hip joint have an effect of being free from weight and being released from gravity.
(6) When the test subject locates the ischial point in the buttocks accommodation space, the pelvis is suspended, the ischial abuts against the pressing top surface, the pelvis is stabilized, and the waist is also stabilized. Since the waist is stable, the posture is stable, and the waist is not tired as it is not necessary to step on to support the posture. It has the effect of not hurting.
(7) If the subject's posture is fixed in a so-called correct posture, and it is attempted to maintain this for a long time, some muscles are strained and tired, and eventually pains. There is a theory that the body moves unconsciously or changes its posture in order to reduce the muscle tension that occurs. It is a mechanism to press and stretch the pressure point and muscles using weight and body movement, and it does not fix the posture or maintain this for a long time, so some muscles are strained and tired and hurt Has the effect of being eliminated.

The present invention is a mechanism for rotating the spit back and forth in the subject direction to form the buttock accommodation space, the pressing top surface, and the subject support portion, and pressing and extending the pressure point and the muscle. An effect as shown in FIG. 11 is obtained.
(1) As shown in FIG. 4 and FIG. 8, when the test subject H positions the ischial point 44 in the buttocks accommodation space portion 6 and places the upper body on the backrest 29, the pressing top surface 7, pressing top surface 8, subject The pelvis 57 is suspended and held while being supported by the support portion 9 and the backrest 29. As the pelvis 57 becomes a weight, the muscles in the extension range W are pulled downward as shown by the arrow Y1 and extended, and further weight is not loaded and released from gravity. further,
(2) As shown in FIG. 4 and FIG. 8, when the test subject H places the ischial point 44 in the buttocks accommodation space 6 and places the upper body on the backrest 29, the pressing top surface 7, pressing top surface 8, subject The support portion 9 is supported by the backrest 29. The pressing top surface 7 contacts the pressure points and muscles around the subject's thighs, and the pressing top surface 8 contacts the pressure points and muscles around the junction between the buttocks and thighs of the subject, and the pressure points and muscles contacting the test subject It is pressed and extended by H's weight and body movement.
(3) As shown in FIG. 5 and FIG. 9 (A), when the subject H is positioned in the buttocks accommodation space 6, the scissor 88 is abutted against and supported by the pressing top surface 7 and the pressing top surface 8. .
The pressing top surface 7 abuts on the pressure points and muscles around the connection between the hips and thighs and around the front of the ischium 88, and the pressing top 8 around the back surface of the ischium, as shown by arrow Y1 Be loaded. The contact point and muscle are pressed and further stretched by the motion of the subject H's body.
(4) As shown in FIG. 6 and FIG. 9 (B), when the subject H is positioned in the buttocks accommodation space 6, the scissor 88 is supported by being abutted against the pressing top surface 7 and the pressing top surface 8 . Further, when the subject H places the upper body in the backrest 29, the upper body becomes a ladder with the backrest 29 as a fulcrum, and the pelvis 57 is pushed forward in the subject direction as shown by the arrow Y2, and the sciatic 88 is pressed Pressing against the surface 8, the acupressure point and muscles around the rear of the ischial 88 are pinched between the pressing top surface 8 and the ischial 88, pressed by weight and stretched by the movement of the body. Further, the pressure points and muscles around the connection between the buttocks and thighs or around the front of the ischium 88 abut the pressing top surface 7 and are pressed by weight, and are extended by the movement of the body.
(5) When the subject H is positioned on the seat surface of the chair and places the upper body in the backrest, the upper body becomes a ladder with the backrest as a fulcrum, and the pelvis is pushed forward in the direction of the subject. The hip bone slides forward on the seat surface and the thigh is pushed forward. Then, the angle of the pelvis is changed, the pelvis is bent, the spine is pulled, and there is a theory that the physiological S-shaped curve is broken and the posture becomes worse. As shown in FIG. 10, when the pelvis 57 is suspended and the ischial point 44 floats up and the pressing top surface 8 abuts on the front of the ischium 88, the isometric point 44 is stabilized and the pelvis 57 naturally Standing up, the spine is stretched and a physiological S-shaped curve 90 is formed.
(6) When the subject is positioned on the seat of the chair, the sedental point is in contact with the seat and the weight is loaded, and there is a theory that the repulsive force generated on the seat is loaded on the waist and the back hurts, and controls the subject's posture. There are chairs and cushions designed to reduce or disperse this repulsive force. As shown in FIG. 10, when the test subject H positions the ischial point 44 in the buttocks accommodation space portion 6 and places the upper body on the backrest 29, the pressing top surface 7, the pressing top surface 8, the subject support portion 9, the back The pelvis 57 is suspended and held while being supported by a crook 29. Since the ischial point 44 does not float and contact the seat surface, no repulsive force is generated, and the back does not hurt.
(7) When the subject H locates the ischial point 44 on the seat surface of the chair and leans back to the back, the waist is pushed forward in the subject direction. The seat frame slides on the seat surface and the waist can not be stabilized. If the lower back is unstable, the posture becomes unstable, and the lower back stretches to stabilize the posture, so there is a theory that the lower back becomes tired and painful. However, as shown in FIG. 11, when the subject H is positioned in the buttocks accommodation space portion 6 and the upper body is inclined to the backrest, the ischial point 44 lifts away from the seat surface 80. Depending on the shape of the subject, the seat surface 80 may be touched, but in either case, the front of the seat bone 88 abuts on the pressing top surface 8. When the front portion of the ischium 88 is pressed against the pressing top surface 8, the isometric point 44 can not move. If you try it, your waist will be stable and your posture will be stable. The waist does not get tired or hurt as it does not have to be stepped to stabilize the posture.

  The lower back buttock presser 1 of the present embodiment is a cushion type. However, it is also possible to construct a chair type using all or part of the structure.
