Description

  The present invention relates to a pelvic correction belt.

To prevent or correct various problems such as back pain, body shape change, or urine leakage due to body shape change due to the pelvis being displaced or loosened In addition, a pelvic correction belt is used.
Conventional pelvic correction belts are used by tightening the pelvis with elastic belts, but when mounting, to adjust the tightening degree, wrap around while adjusting the length like a general belt (For example, refer to Patent Document 1).
The pelvic correction belt is difficult to walk when wrapped around the base of the bone of the leg. Because it is not possible to correct, it has been wound around a narrow band of pelvis.

However, in many cases, the force for tightening the pelvis is weak only by adjusting the winding length and adjusting the tightening degree.
On the other hand, there is also a pelvic correction (reinforcement) belt in which an auxiliary belt having elasticity is further wound around the belt body in order to reinforce the force to support the pelvis with strong elasticity (see, for example, Patent Document 2). . That is, an auxiliary belt is connected to a part of the belt main body. First, the belt main body is wound around the pelvis, and then the belt belt is attached to the belt main body with a hook-and-loop fastener or the like while grasping and stretching both ends in the longitudinal direction of the auxiliary belt. I try to fix it.
In addition, as a low back pain band, there is one in which an auxiliary belt of a pelvic correction (reinforcement) belt is V-shaped (for example, see Patent Document 3).

However, users with relatively weak power, such as elderly people and postpartum women who tend to affect the pelvis with aging and childbirth, should wear both ends of the elastic auxiliary belt in the proper positions. difficult. In particular, as described above, when the pelvic correction belt is intended to be wound around a specific band of the pelvis, the width of the band is narrow, so that the difficulty of positioning increases only.
An object of the present invention is to provide a pelvic correction belt that solves the above-described problems and can be securely clamped while being easily positioned.

  According to the first invention, the above-mentioned problem is a belt-like shape that is wound around the human pelvis with elasticity, wherein one end in the longitudinal direction and the other end are detachable, and the longitudinal A positioning belt having a back surface portion having no elastic force in a substantially central region in the direction, and a belt-like shape that is overlapped with the positioning belt and wound around the positioning belt with an elastic force, and has both longitudinal end portions A fastening belt that is detachably attached to the outer surface of the positioning belt, and the fastening belt has at least a strong elastic force as compared with the positioning belt and has a central portion in the longitudinal direction. Is fixed to the back surface portion of the positioning belt, and the positioning belt is formed with a bag-like portion covering at least an area excluding the both end portions of the fastening belt. The tightening belt can be moved back and forth along the longitudinal direction on the inner side, and the width dimension of the inner side of the tightening belt corresponds to the width dimension of the tightening belt. This is achieved by a pelvic correction belt that is used as a guide for regulating the pelvis.

  According to the configuration of the first invention, the pelvic correction belt is wound around the pelvis of the human body, and has a weak elastic force that allows one end and the other end in the longitudinal direction to be attached and detached, and positioning A tightening belt having a strong elastic force that is superposed on the belt and that can be attached to and detached from the positioning belt at both ends in the longitudinal direction. For this reason, first, a body-side positioning belt is used to specify a portion to be tightened in advance, and the pelvis is roughly tightened, and then the pelvis is connected with the back surface of the positioning belt. The surroundings can be tightened. And when winding the tightening belt, the part to be tightened with the positioning belt has already been specified, so it is not necessary to apply the positioning force, and the elastic force is fully utilized to strongly The belt can be attached to the outer surface of the positioning belt while pulling to tighten.

Moreover, although the center part of the longitudinal direction of this clamping belt is being fixed to the back part of the positioning belt, the back part of this positioning belt does not have elastic force in the longitudinal direction. Accordingly, the tightening belt can be stretched in a balanced manner from the central portion toward both ends with the back surface portion having no elastic force in the longitudinal direction and being difficult to be displaced as a base point.
Further, the positioning belt is formed with a bag-like portion that covers an area excluding at least both ends of the fastening belt, and the inside of the bag-like portion can be advanced and retracted along the longitudinal direction of the fastening belt. The width dimension of the tightening belt is made to correspond to the width dimension of the tightening belt, thereby limiting the movement of the tightening belt in the width direction. For this reason, even when the fastening belt has a strong elastic force when gripping and stretching both ends of the fastening belt in the longitudinal direction and fixing it to the abdominal region, the bag-like portion serving as a guide For the user, it is possible to effectively prevent the shake in the width direction which is the vertical direction. Therefore, even if the force is weak, positioning in the width direction when winding the tightening belt around a narrow band is facilitated, and the force in the extending direction can be increased by not having to apply the force to the positioning in the width direction. Can be tightened.

  According to a second invention, in the configuration of the first invention, a cushioning material having elasticity in the thickness direction is provided on a back surface portion of the positioning belt, and the tightening belt has a plurality of layers in the thickness direction. The belt layer on the human body side is fixed to both ends of the cushion material, and the outer belt layer is arranged not to be fixed to at least the both ends of the cushion material so as to overlap the cushion material. Features.

  According to the configuration of the second invention, the back surface portion of the positioning belt is provided with a cushioning material having elasticity in the thickness direction, which not only enhances the feeling of wearing but also improves the adhesion between the back surface portion serving as the base portion and the waist. Increase and hold securely. On the other hand, since the belt layer on the human body side is fixed to both ends of the cushion material, the belt layer on the human body side stretches the cushion material toward both ends of the positioning belt. To prevent the cushioning material from being bent. And since the outer belt layer is arranged so as to overlap the cushion material, the outer belt layer is displaced toward the human body side when pulled toward both ends and presses the cushion material against the human body, Prevents the position of the cushioning material that becomes the base point when winding the pelvic correction belt from shifting. In this way, when winding the tightening belt, the cushioning material can be reliably used as a base point, and both ends thereof can be pulled while applying a stable force. Therefore, the effect of the first invention is more effective. Can be demonstrated.

According to a third aspect of the present invention, in the configuration of the first or second aspect of the invention, the opening in the bag-like portion is on the end side in the longitudinal direction on the lower side compared to the upper side in the width direction. It is characterized by being arranged in.
According to the configuration of the third aspect of the invention, the opening in the bag-like portion is arranged closer to the end in the longitudinal direction on the lower side than on the upper side in the width direction. Therefore, the bag-shaped part is longer in the longitudinal direction when it is pulled in the longitudinal direction while pressing the tightening belt to the lower side, which is the direction in which the force can be more easily applied. .

  As described above, according to the present invention, it is possible to provide a pelvic correction belt that can be easily tightened while being easily positioned.

Before describing the preferred embodiment of the present invention, the point that the pelvic correction belt is wound aiming at a narrow band of the pelvis will be outlined with particular consideration of changes in the pelvis after birth, and then pelvic correction The belt will be described.
FIG. 1 is a front view of the periphery of a pregnant woman's pelvis and is a perspective view of tissues such as skin and muscle. FIG. 2 is a schematic cross-sectional view of the human body cut along the line AA in FIG.

As shown in FIG. 1, the pelvis 1 is composed of a pair of hipbones 3 and 3 arranged symmetrically about a sacrum 2, and each hipbone 3 is an iliac bone 4 and a cartilage with little movement. It has an acetabulum 5, a pubic bone 6 that is cartilage, and a rib 7, and a bone 8 at the base of the femur enters a recess formed from the side of the pubic bone 6 to the acetabulum 5. .
The interval L between the pair of pubic bones 6 and 6 is different between the 5th month and after the pregnancy and the several months after the birth, and the greater the interval L between the pubic bones 6 and 6 (the pelvis is). It was found that the more relaxed, the greater the back pain and body shape change.

  In this way, the reason for the spread of the pubic bone is, for example, in the case of a pregnant woman, because the fetus in the uterus passes through the uterine ostium, as shown in FIG. 2, to relax the muscles around the uterine ostium and prepare for childbirth. It is believed that there is. On the other hand, in recent years, along with social phenomena such as working together and nuclear family, it often moves immediately after giving birth, and for this reason, the interval L between pubic bones is difficult to return due to the weight of organs and the like that have added gravity. The period of recovery of pelvic looseness tends to be prolonged compared to the past, about 5 months after the birth of pelvic loosening, and the number of cases where pelvic loosening does not fully recover has increased. Yes. In addition, such a mechanism is not unique to pregnant women, but also applies to elderly people. That is, as the elderly becomes older, the function of the muscles around the pubic bones 6 and 6 and the like decreases, so the distance L between the pair of pubic bones 6 and 6 increases. Problems such as urine leakage are likely to occur.

  Therefore, when winding the pelvic correction belt, it is necessary to wind the pair of pubic bones 6 and 6 so that the distance L between the pubic bones 6 and 6 is returned to a normal distance. However, as described above, since the base bone 8 of the leg enters the recess formed from the side of the pubic bone 6 to the acetabulum 5, if a belt is wound around this band, Since the root is tightened, not only does it become difficult to walk, but it also tends to shift with walking. Further, since the iliac 4 is a position corresponding to the sacrum 2 and is separated from the pubic bone 6, even if a belt is wound around this portion, the effect is hardly seen. Therefore, it is most effective to wind the pelvic correction belt so as to be positioned between the upper side of the acetabulum 5 and the lower side of the iliac 4 (band M indicated by a one-dot chain line in FIG. 1).

The pelvic correction belt of the present invention is preferably mounted to correct the pelvis in this way.
Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. The embodiment described below is a preferred specific example of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these forms.

3 to 5 show a pelvic correction belt 10 according to an embodiment of the present invention, and FIG. 3 is a schematic perspective view when viewed from the front side of the human body with the pelvic correction belt 10 wound. FIG. 5 is a schematic perspective view when viewed from the back side in a state where the pelvic correction belt 10 is wound, and FIG. 5 is a schematic sectional view taken along the line BB of FIG. 3 and 4, the human body is shown in a transparent manner.
As described above, the pelvic correction belt 10 is wound so as to be able to be wound between the upper side of the acetabulum 5 and the lower side of the iliac 4 in order to narrow the distance between the pair of pubic bones. The overall width W1 is formed to be relatively narrow, and in the case of this embodiment, the overall width W1 is set to about 7.5 cm assuming a postpartum woman.
The pelvic correction belt 10 includes a belt-like positioning belt 30 and a belt-like tightening belt 20 that is overlapped at least outside the body-side surface of the positioning belt 30.

  The tightening belt 20 has a function of winding around the pelvis of the human body F and tightening the pelvis, and can be said to be a belt body. That is, the fastening belt 20 has a strong elastic force that expands and contracts along the longitudinal direction, and the pelvis is fastened with this elastic force. The fastening belt 20 of the present embodiment is provided with a plurality of elastic bodies such as rubbers extending in the longitudinal direction in consideration of air permeability and generating an elastic force in the longitudinal direction. The positions of the plurality of elastic bodies along the side are fixed with a helical synthetic thread along the width direction.

  The fastening belt 20 has both longitudinal end portions 21 and 22 detachable from the abdominal region. Specifically, both ends 21 and 22 of the fastening belt 20 are arranged on the front of the abdomen from both sides as shown in FIG. 3 when not being pulled. And both ends 21 and 22 are gripped by hands and pulled toward the center of the front of the abdomen, and are displaced to the center of the front of the abdomen so that the hands do not cross each other. It can be mounted on the surface.

In the case of the present embodiment, a detachable engagement means such as a hook-and-loop fastener is used as the detachable means. Specifically, as shown in FIG. A hook-shaped male surface fastener 23 provided on each back surface (body-side surface) of both end portions 21 and 22 is engaged with a female surface fastener 31 provided on the surface of the positioning belt 30. Yes. The attaching / detaching means is not limited to a hook-and-loop fastener as long as an extra force is not applied for attaching / detaching, and may be various engaging means such as a plurality of hooks and hooks.
Note that both end portions 21 and 22 of the fastening belt 20 are portions that are gripped by hand when winding, and if this portion is given an elastic force, the hand becomes unstable and positioning becomes difficult. 23 and 23 are formed so as not to have elastic force.

The positioning belt 30 is a belt-like shape that overlaps the human body F side of the fastening belt 20, and, like the fastening belt 20, in a specific region of the pelvis (between the acetabulum and the lower side of the iliac bone). It is designed to be wrapped around.
The positioning belt 30 is a belt mainly having a function for allowing the above-described tightening belt 20 to be wound at an appropriate position. That is, after the positioning belt 30 is attached to a specific region of the pelvis and the pelvic correction belt 10 is positioned, the pelvis is firmly tightened by the tightening belt 20 connected to the positioning belt 30. Yes.

  Specifically, as shown in FIG. 3, the positioning belt 30 is slightly larger than the width W2 of the fastening belt 20, and the width W1 of the entire pelvic correction belt 10 becomes the width of the positioning belt 30 as it is. Then, the positioning belt 30 is wound around a specific region of the pelvis with a relatively weak force so as to fix one end 32 and the other end 33 in the detachable longitudinal direction.

The certain amount of force that is wound around the specific region is elastic enough to prevent the positioning belt 30 from being displaced at least when it is wound.
In the case of this embodiment, in order not to impair the function of positioning in a specific region (that is, even a non-powerful person can easily perform positioning), an elastic force is applied in the longitudinal direction so that the position does not shift. Thus, the force applied when tightening with the subsequent tightening belt 20 can be reduced as much as possible.

  Specifically, the positioning belt 30 is formed of, for example, a power net in consideration of air permeability as a whole, and other members (for example, a cushion material 40 to be described later) are formed on the end portions 32 and 33 and the back side. ) Is added or stitched to reduce the elastic force of the power net. The elastic force is applied only to both side portions 30 b and 30 b that are in contact with both side regions of the positioning belt 30. That is, the one end portion 32 and the other end portion 33 are portions that are gripped when being wound, and if this portion is given an elastic force, the hand becomes unstable and positioning becomes difficult. , 31 weakens the elastic force. Further, since the back side becomes a base point around which the pelvic correction belt 10 is wound as will be described later, the positioning becomes difficult when this portion also moves. For this reason, the elastic force is given only to both the side parts 20b.

Further, as means for making the one end portion 32 and the other end portion 33 detachable, a hook, a fastener, a buckle, or the like may be used. However, in this embodiment, the fastening belt 20 can be easily attached as described above. A hook-and-loop fastener is used so that the hook-and-loop fastener can be attached and detached, and a hook-and-loop fastener 31 on the female side is provided on the surface of the positioning belt 30. That is, as shown in FIG. 5, the male surface fastener 34 provided on the back surface of the one end portion 32 is provided on the surface of the other end portion 33, and the surfaces on the both end portions 22 side of the fastening belt 20. It engages with the female surface fastener 31 on the other end 33 side to which the fastener 23 is attached.
As shown in FIGS. 4 and 5, the rear surface of one end portion 32 is slightly spaced from the male side surface fastener 34, and next to the same area and surface fastener 34. A female-side hook-and-loop fastener 35 having a shape is provided. Therefore, when the hook-and-loop fastener 34 and the hook-and-loop fastener 35 are bent and the fasteners are engaged with each other to perform washing, it is possible to prevent dust from adhering to this portion or damaging other laundry. ing.

As shown in FIGS. 4 and 5, the spine R of the positioning belt 30 and the back surface portion 30 a that abuts on the peripheral area thereof are integrated with the fastening belt 20. As described above, the back surface portion 30a does not have an elastic force in at least the longitudinal direction, and becomes a base point when being wound. That is, the central portion OP in the longitudinal direction of the positioning belt 30 is assigned to the position of the spine R serving as the central axis in the human body, and the back portion that does not have elasticity and is difficult to move passes through the left and right flank. The balance is wrapped around the front of the abdomen. Moreover, since the center part of the longitudinal direction of the fastening belt 20 is connected to the back surface part 30a, the fastening belt 20 can be stretched and tightened from the center part toward both ends.
In addition, the above-mentioned “not having elastic force in the longitudinal direction” means that the elastic force is not positively provided in the longitudinal direction, and the elastic force is present in the longitudinal direction. If there is a portion, it means that the elastic force of the portion is attenuated, and it is a matter of course that includes a case where there is a slight elastic force in the longitudinal direction.

Further, as shown in FIG. 5, a cushion material 40 having elasticity in the thickness direction is provided on the back surface portion 30 a of the positioning belt 30. The cushion material 40 is a member that not only enhances the wearing feeling of the pelvic correction belt 10 but also keeps the back surface portion 30a in close contact with the back and prevents it from moving during winding. As a function can be enhanced.
In the present embodiment, as shown in FIG. 4, the cushion member 40 and the fastening belt 20 are stitched at a substantially central portion of the outer surface on the back side so that the central portion OP can be in good contact with the spine R. A substantially rectangular mark 30c is laminated at the stitching position in the thickness direction. It should be noted that the shape of the mark 30c is a substantially trapezoidal shape obtained by cutting the vertices of an isosceles triangle as shown in FIG. A substantially diamond shape or the like may be employed.

The pelvic correction belt 10 of the present embodiment is formed with the above-described characteristics, and further has the following characteristics.
First, further features of the positioning belt 30 will be described.
As shown in FIGS. 3 and 5, the positioning belt 30 is formed into a bag-like portion 37 so as to cover at least the region excluding both end portions 21 and 22 of the fastening belt 20, and the width dimension inside the bag-like portion 37 is set. It is a guide that regulates the movement of the tightening belt 20 in the width direction by making it slightly larger corresponding to the width dimension W2 of the tightening belt 20.

Specifically, as shown in FIG. 3, the positioning belt 30 allows at least both end portions 21 and 22 of the tightening belt 20 to be exposed and gripped to the outside, and covers the periphery other than the both end portions 21 and 22. A bag-like portion 37 is formed as described above.
The bag-like portion 37 is a body side layer that is a fabric layer forming the positioning belt 30 as shown in FIG. 7, which is a schematic end face obtained by cutting the bag-like portion 37 in the width direction and looking at its end face. 30d and the outer surface layer 30e are laminated | stacked on the thickness direction, and it is made into a bag shape by sewing through piping 30f and 30f at the width direction (user's up-down direction) both ends.

In the region of the bag-like portion 37, the fastening belt 20 is disposed inside the bag-like portion 37 (outside the body side layer 30d and inside the outer surface layer 30e). The positioning belt 30 is wound around. At this time, the bag-shaped portion 37 is formed so that the inner side (inner space) width dimension W3 is slightly larger than the width dimension W2 of the tightening belt 20 to accommodate the tightening belt 20.
Thus, when the fastening belt 20 is extended along the longitudinal direction (the direction of the arrow P in FIG. 5), the inner surface of the bag-like portion 37 in FIG. 7 and the outer surface of the fastening belt 20 are in contact with each other. The uppermost portion and the lowermost portion in the width direction serve as a guide by restricting the movement of the tightening belt 20 in the width direction (vertical direction in FIG. 7).

In addition, the bag-shaped part 37 is arrange | positioned at least to the front (front abdomen) side rather than the flank of a human body so that the function as the guide can be exhibited reliably, More preferably, of this embodiment As described above, it is preferable to cover the whole of the fastening belt 20 except for both end portions 21 and 22.
Further, if the width dimension W3 inside the bag-shaped portion 37 with respect to the tightening belt 20 is too small, the movement of the tightening belt 20 is excessively restricted and it becomes difficult to operate, and if it is too large, the tightening belt accompanying the operation. Therefore, it is difficult to mount the belt 20 at an appropriate position, and the dimensions must be determined in consideration of contact between the fastening belt 20 and the inner surface of the bag-shaped portion 37, friction, and the like. In the case of the present embodiment, the width dimension W2 of the fastening belt 20 is about 5 cm, and the width dimension W3 inside the bag-shaped portion 37 is designed to be about 6 cm, with gaps S of about 5 mm above and below each. The one clearance S with respect to the fastening belt 20 is set to a width of about 5% to 15%.

  Further, as shown in FIGS. 3 and 5, a bag-like portion 37 for exposing both end portions 21 and 22 of the fastening belt 20 to the outside so as not to apply an excessive force when the fastening belt 20 is pulled. A member 45 having a low coefficient of friction with the fastening belt 20 is arranged in a piping shape on the end surface 44a of the opening 44 of the opening. In the case of this embodiment, cotton or polyester is used as a member having a low friction coefficient. By providing this piping-shaped member 45, the width when the openings 44, 44 are formed vertically is configured to be slightly smaller than the width dimension W3 inside the bag-shaped portion 37.

  Further, in the case of the present embodiment, the bag-like portion 37 accommodates all the portions other than the both end portions 21 and 22 held by the hand of the fastening belt 20 so as to cover the fastening belt 20 with the outer surface layer 30e. However, when most of the fastening belt 20 is accommodated in the bag-like portion 37 and the longitudinal movement of the fastening belt 20 becomes slow, for example, adjacent to both end portions 21 and 22 of the fastening belt 20. It is also possible to accommodate only the regions that have been exposed and to expose other regions.

  Furthermore, in this embodiment, as shown in FIG. 3, the opening 44 in the bag-like portion 37 has a positioning belt on the lower side (foot side) more than the upper side (head side) in the width direction. 30 are arranged on the end portions 32 and 33 side in the longitudinal direction. Here, the opening 44 in the bag-shaped portion 37 is formed such that the lower side in the width direction extends toward the end portions 32 and 33 in the longitudinal direction, and the lower side is longer toward the center side of the abdomen. It is formed so as to cross the width direction obliquely from the top to the top. That is, as shown in FIG. 8 in which both ends 21 and 22 of the tightening belt 20 are gripped and pulled, the tightening belt 20 having a strong elastic force can be easily pulled toward the crotch where the force can be applied. Since the lower side 37a (the lower side in FIG. 8) of the bag-like portion 37 is longer when pulled in the direction E because it is in the diagonally downward direction E, the movement of the fastening belt 20 is performed over a longer time. The tightening belt 20 can be tightened while being regulated and pressed down.

Next, further features of the fastening belt 20 will be described.
The fastening belt 20 has a plurality of layers in the thickness direction, and as shown in FIG. The human body side belt layer 28 is stitched to both end portions 40 a and 40 b in the longitudinal direction of the cushion material 40. Further, the outer belt layer 27 is arranged so as to be overlapped on the outer side of the cushion material 40 without being connected to at least both end portions 40 a and 40 b of the cushion material 40. In the case of this embodiment, the outer belt layer 27 is connected only to the central portion OP of the cushion material 40.

Thereby, when the both ends 21 and 22 of the tightening belt 20 are gripped and pulled, the belt layer 28 on the human body side pulls both ends 40a and 40b of the cushion material 40 in the directions of arrows E1 and E1 in FIG. The cushion material 40 is prevented from being bent.
Further, since the outer belt layer 27 is arranged not to be connected to at least both end portions 40a and 40b of the cushion material 40 but to be overlapped with the cushion material 40, the both end portions 21 and 22 of the tightening belt 20 are arranged. When grasped and pulled, the body is displaced toward the human body (in the direction of arrows E2 and E2), the cushion material 40 is pressed against the back, and the back region that becomes the base point when the pelvic correction belt 10 is wound is more closely attached to the human body. Thus, the base point can be prevented from shifting.

The embodiment of the present invention is configured as described above, and the pelvic correction belt 10 is attached to a specific region of the pelvis in advance with a positioning belt 30 having a weak elastic force, and then is connected to the positioning belt 30 with strong elasticity. Since the pelvis is tightened with the tightening belt 20 having a force, when tightening with the tightening belt 20, it is not necessary to apply a force for positioning, and the pelvis is strongly and fully utilized by using the elastic force. The surroundings can be tightened.
Further, the positioning belt 30 is formed into a bag-like portion 37 so as to cover at least the region excluding both end portions 21 and 22 of the fastening belt 20, and the width dimension inside the bag-like portion 37 is set to the width dimension of the fastening belt 20. By making it correspond, the guide which regulates the movement of the tightening belt 20 in the width direction is formed. For this reason, when the both end portions 21 and 22 of the fastening belt 20 are gripped and stretched in the longitudinal direction and fixed on the surface of the abdominal region of the positioning belt 30, the bag-shaped portion 37 serving as a guide is used in the width direction. Shake can be effectively prevented. Therefore, even when a weak user tries to put on a narrow specific part above the narrow pubic bone 6 and below the iliac 4, positioning in the width direction is facilitated, In addition, since it is not necessary to apply a force to positioning in the width direction, tightening can be performed by applying a force in the extending direction.

  The present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the claims. For example, in the present embodiment, cloth is used for the whole, but a molded body may be disposed depending on a contact portion such as the back side. Further, in this embodiment, the whole feeling is improved by forming the material with air permeability, but a material without air permeability may be used, and a heat retaining function may be provided on the back side or the like. You may comprise so that it can use the material which has, or can provide a pocket etc. and can heat-retain.
