Abstract

PROBLEM TO BE SOLVED: To provide a support device in a seated state capable of reducing the load of the muscle group of the pelvis and one's waist measurement causing lumbago or the distortion of the pelvis by the accumulation of the fatigue in the muscle group of the pelvis and one's waist measurement because the muscle group of one's waist measurement is strained by the force acting on the pelvis by one's body weight of the upper half of the body generated when a person sits down on a chair and the pelvis and thighs are widened left and right but fatigue is accumulated in the pelvis and the muscle group of the pelvis and one's waist measurement.SOLUTION: The support device in the seated state is arranged in close contact with thighs so as to hold the left and right thighs by left and right separated support devices and the interval between the left and right support devices is made simply adjustable corresponding to the correction degree of the pelvis. Further, the support device is used along with the seat or cushion of the chair to provide the support device in the seated state excellent in design properties and easiness to use.

Description

  The present invention relates to a support in a sitting position that corrects pelvic distortion, reduces back pain, and reduces the burden on the waist.

  When a person sits on a chair, the weight of the upper body acts on the pelvis, and this force strains the muscles around the waist and spreads the pelvis and thighs to the left and right. Fatigue accumulates in the muscle groups around the waist, causing back pain and pelvic distortion.

  As a result, the spine is twisted in either the left or right direction together with the pelvic region, leading to distortion of the entire body.

  In addition, low back pain and pelvic distortion make it difficult to maintain the correct posture when sitting in a chair, further worsening the posture, leading to tilting of the axial center of the stoop, etc., reducing visual acuity and concentration, compressing internal organs, This may cause a decrease in resistance to life and lifestyle-related diseases.

  Conventionally, from the viewpoint of treating low back pain and pelvic distortion, there are techniques such as body trimming, treatment of the pelvis and around the waist, and a method of wrapping the pelvis with a rubber belt, etc. A method for correcting the pelvis has been proposed (for example, Patent Document 1 and Patent Document 2).

  However, human physiques vary widely, and making chairs and seats (or cushions) suitable for each has the disadvantage of becoming too complicated and expensive.

  In addition, the degree of pelvic distortion is various, and in addition, it is necessary to correct the pelvis over time, and even if it is somewhat elastic, the pelvis is fixed at once in a fixed shape. If you try to correct it by restraining it, it may cause more pain and a different form of distortion.

  The present invention is intended to solve the problems of the prior art, and can be used by a wide range of people regardless of the size of the user's body shape or pelvic distortion. The purpose of the present invention is to provide a support device in a sitting state in which the interval can be easily adjusted according to the degree of pelvic correction and can be performed little by little over time to correct the pelvis. is there.

  In order to achieve the above-mentioned purpose, in order to suppress the spread of the pelvis when a person is sitting on a chair, the left and right thighs are sandwiched from the outside of the thigh with the support tool 1 separated to the left and right, and the pelvis is fixed. In this case, the force to spread the thigh is generated between the support 1 and the chair seat 11 (or the cushion 10) by the vertical force acting on the lower support 3 of the thigh. The cushioning material is made stationary by resisting with frictional force.

  In the present invention, since the left and right support devices are separated from each other, depending on the material of the surface of the chair seat 11 (or the cushion 10), it may be considered that the individual support devices are slippery and do not stand still. About the support tool of the present invention, the left and right support tools can be combined with a connecting member such as a string, and the pelvis can be fixed by using the seat 11 (or the cushion 10) of the chair that is slippery only with the individual support tools. It is possible to do.

  With respect to the support device of the present invention, the left and right support devices 1 can be joined by the connecting sheet 7 so that the left and right support devices do not spread outward and the distance between them can be kept constant. Fixing tools 12 such as hook-and-loop fasteners and snap buttons are attached to the lower surface of the support device 1, and the position to be connected is freely adjusted, and the most effective position for treatment is selected at any time to correct the pelvis little by little. By using the chair seat 11 (or the cushion 10) instead of the connecting sheet, it can be used as a part of the chair or a part of the cushion. It is characterized by excellent usability.

  The above contents are summarized as technically specific items as follows.

  That is, in the present invention, in a sitting position in which a person is seated on a chair while the thigh is in contact with the seating surface, in the sitting position that suppresses movement of the thigh outwardly in order to suppress the spread of the person's pelvis. A lower support part that is sandwiched between the thigh and the seating surface and that acts on its own weight of the thigh and has flexibility, and is in close contact with the outer surface of the thigh A side support portion that protrudes upward from one side position of the lower support portion is provided so as to suppress movement of the thigh in the outward opening direction.

  According to this, in order to suppress the spread of the pelvis when a person is sitting on a chair, the support device is placed in close contact with the thigh so that the thigh is sandwiched from the left and right, and the left and right thighs are arranged on both the left and right sides. If only one of the left and right sides is required, use the support only on the required side, and if both are required, use both the left and right support. do it.

  Moreover, in the said invention, it is comprised by a pair of right and left, and each lower support part of the left-right both-sides position can also be made to provide the connection member for connecting these both lower support parts.

  According to this, even if the surface of the seat (or cushion) of the chair on which the support is placed is slippery and the support is difficult to stand still, the distance between the left and right supports can be kept constant.

  In this case, the connecting member may be configured such that the interval between the lower support portions at the left and right side positions can be changed and adjusted.

  According to this, it can be used by a wide range of people regardless of the size of the user's body shape or pelvic distortion, and the interval of the support can be easily adjusted according to the degree of pelvic correction, It can be done by taking a small amount of time to correct.

  Furthermore, in the said invention, it is provided with the connection sheet | seat mounted in the said seat surface, and the connection part which connects both detachably is provided in the upper surface of the said connection sheet | seat, and the lower surface of a lower support part. You can also.

  According to this, it is possible to freely adjust the connecting position, select the position most effective for treatment as needed, and correct the pelvis little by little over time.

  As described above, the support device in the sitting position of the present invention can be used regardless of the size of the user's body shape or the distortion of the pelvis, and the interval between the support devices can be easily adjusted according to the degree of pelvic correction. Thus, it is effective not to perform correction of the pelvis at a time, but to take a small amount of time to prevent pain and new distortion caused by the correction.

  Since the structure of the present invention is simple and small-scale, it is excellent in economic efficiency.

It is a side view which shows the use condition of the support tool in embodiment of this invention. It is a front view which shows the use condition of the support tool in embodiment of this invention. It is the perspective view which looked at the support in embodiment of this invention from diagonally upward. It is a section explanatory view of the support of a 1st embodiment. It is a section explanatory view of the support of a 2nd embodiment. It is a section explanatory view of the support of a 3rd embodiment. It is a section explanatory view of a support of a 4th embodiment. It is sectional explanatory drawing of the support tool of 5th Embodiment.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  1 to 3 are schematic views of a support according to a first embodiment of the present invention. FIG. 1 is a side view seen from the lateral direction, FIG. 2 is a front view seen from the front, and FIG. It is the perspective view seen from diagonally upward.

  The support tool shown in FIGS. 1 to 3 is arranged in close contact with the thigh so as to sandwich the thigh from the left and right sides in order to suppress the spread of the pelvis when a person is sitting on the chair.

  This supports both thighs so that the left and right thighs do not spread to the left and right sides.

  The support 1 is formed of a cushion material having a predetermined flexibility.

  As the forming material, for example, a foamed plastic material obtained by firing urethane, polystyrene, etc., a resin material such as polyester, a rubber sponge, or a woven or non-woven fabric filled with a filler such as buckwheat or red beans Etc.

  The lower part (for example, the lower support part 3 described later) of the support tool 1 wraps around the center of each thigh below the thigh. By the frictional force due to the vertical force from the thigh acting on this part, The support tool 1 is prevented from moving outward against the force that the thigh is trying to open.

  FIG. 4 is a cross-sectional explanatory view of the support 1 of the first embodiment, and is a specific example when the frictional force between the support 1 and the chair seat 11 (or the cushion 10) under the support 1 can be sufficiently expected. This is an example (for example, when the support 1 is a foamed plastic material and the sheet 11 or the cushion 10 is a non-woven fabric).

  The support 1 is composed of a thick side support 2 positioned on the outer side of the thigh and a lower support 3 supporting the lower part of the thigh. A concave curved surface 31 is formed from the upper surface of the lower support 3 to the side support 2. It is formed as follows.

  The concave curved surface 31 receives and supports the side portion and the lower portion of the thigh.

And since the support tool 1 is formed, for example with a foaming plastic material, it has moderate elasticity, and thereby, the frictional force from the lower thigh support part 3 which wraps around the lower thigh is applied to the side support part 2. To be able to tell.

  In the case of such a support tool 1, if only one of the left and right sides is necessary, use the support tool 1 only on the required side. If both the left and right sides are required, use both the left and right support tools 1. do it.

  That is, because the support 1 is intended to keep the pelvis in a normal position, an effect can be expected only by using only the thigh of the leg portion on the non-normal side (the side to be opened).

  Therefore, this support tool 1 is used by one thing only on one side, a pair on both sides, or two or more front and back.

  FIG. 5 is an explanatory cross-sectional view of the support 1 of the second embodiment, and a thin plate 4 is attached to the bottom of the support 1 of FIG.

  As a material for forming the thin plate material 4, for example, a foamed plastic such as rubber sponge or urethane to increase the frictional force on the lower surface of a metal plate such as an iron plate as a main material or a resin material plate such as polyester. There are those with a thin layer bonded.

  Thereby, while preventing the skidding of the support tool 1 more reliably, a user's thigh can be hold | maintained in an appropriate position.

  That is, it is possible to increase the rigidity of the support 1 (particularly, the lower support part 3 at the lower part of the thigh) and reliably transmit the frictional force from the lower support part 3 around the lower part of the thigh to the side support part 2. It is something that can be done.

  FIG. 6 is a cross-sectional explanatory view of the support 1 of the third embodiment. The lower support 3 in the support 1 of the second embodiment of FIG. 5 is omitted, and only the side support 2 and the thin plate 4 are used. It is made up of and is economical.

  Even in this case, the thigh can be supported so as not to spread to the left and right sides, and can contribute to the fixation of the pelvis.

  FIG. 7 is a cross-sectional explanatory view of the support tool 1 of the fourth embodiment, and a specific example in the case where the friction between the support tool 1 and the seat 11 (or the cushion 10) of the chair below the support tool 1 cannot be sufficiently expected. (For example, leather with a smooth surface).

  In this case, the left and right supporters 1 and 1 are connected to each other by a connecting member, and the supporters on both sides are prevented from moving outwardly against the force that the thigh is to open.

  Specifically, connecting members (strings, bands, etc.) 5 are bonded to the lower parts of the left and right supports 1, 1, and the connecting members (surface fasteners, snaps) are connected near the center of the left and right thighs. And the like, and the distance between the left and right supports 1 and 1 is kept constant.

  In addition, the connecting portion 6 allows the left and right connecting members 5 and 5 to be detachable so that the distance between the left and right supports 1 can be changed.

  That is, since the connecting portion 6 is composed of a member capable of adjusting the distance between the left and right support devices 1 such as a hook-and-loop fastener and a snap button, for example, the most effective position for treatment (the distance between the support devices 1 and 1). ) Can be selected at any time to correct the pelvis in small amounts over time.

  FIG. 8 is a cross-sectional explanatory view of the support tool of the fifth embodiment, and has a connection sheet 7 that is a connecting member for connecting two support tools to the bottom of the support tool 1 of FIG. 5 or FIG. Yes.

  Fixing devices 12 such as hook-and-loop fasteners and snap buttons are attached to the lower surface of the support device 1 and the upper surface of the connection sheet 7, and the position most effective for treatment can be selected at any time by freely adjusting the connection position. Correction can be performed in small amounts over time.

  The support 1 of the fifth embodiment can be used as a part of a seat of a chair or a part of a cushion.

  Thereby, the support tool 1 in the sitting position excellent in aesthetic design and ease of use can be provided.
