Abstract
Description
本発明は、座った状態で、一定の範囲で椅子自体が、前後左右又は回転が自在となっており、姿勢をバランス良く保持しなければ、自動的に傾斜し、姿勢を正すことが求められる姿勢矯正用椅子に関する。 In the present invention, the chair itself is freely movable back and forth, right and left or within a certain range in a sitting state, and if the posture is not maintained in a well-balanced state, it is required to automatically tilt and correct the posture. The present invention relates to a posture correcting chair.
最近、事務用機器であるパソコン又はゲームなど、座ったままでキーボードを操作する電子機器が非常に多くなっている。この場合、早期に仕事を進める関係から、あるいはゲームに熱中する余り、画面やキーボードに顔を近づけことが多くなるために、姿勢が次第に前かがみになり、近視あるいはドライアイなどの問題も出てきている。
通常、椅子自体の上下の調節が可能であるから、好ましい目の位置や姿勢があり、一般には目の高さが、パソコンよりも上で、見下ろすような姿勢が良いとされているが、これも個人差があって、人それぞれ自前の姿勢を保持しているようである。
Recently, there are a great number of electronic devices that operate a keyboard while sitting, such as a personal computer or a game that is an office device. In this case, because of the fact that the work progresses early or because the player is more enthusiastic about the game, the face often becomes closer to the screen or keyboard, and the posture gradually leans forward, causing problems such as myopia or dry eye. Yes.
Usually, since the chair itself can be adjusted up and down, there are preferable eye positions and postures. Generally, the eye height is higher than the PC and it is said that the posture is good looking down. However, there are individual differences, and each person seems to maintain their own attitude.
しかし、問題はパソコンの長時間の姿勢が問題であり、パソコンの使用時には姿勢を正してはいるが、気がつかない内に、姿勢が悪くなり、著しい疲労感に襲われることが多い。また、最初から非常に悪い姿勢でパソコンの操作を行う人もいる。このような場合に、自動的に姿勢を保持するような機器は存在していない。
他人から、「姿勢が悪いよ」とか言われ、あるいは肩を叩かれる注意を与えられて、その姿勢に気付くことが多い。通常、事務の管理を行って場合には、一斉に休憩時間をとり、回復する職場が存在するが、そのようなことは稀な職場である。
However, the problem is the long-time posture of the personal computer. Although the posture is correct when the personal computer is used, the posture is often deteriorated without being noticed, and the tiredness is often attacked. Some people use a very bad attitude from the beginning. In such a case, there is no device that automatically holds the posture.
Often, someone tells me that my posture is bad, or gives me the attention to hit my shoulder. Usually, when managing office work, there are workplaces that take a break all at once and recover, but this is rare.
以上から、座ったままで、正しい姿勢が保持できれば、長時間のパソコン操作でも、姿勢が悪くなり、著しい疲労感に襲われることを避けることが可能であると思われるのであるが、現在のところ、そのような機器は存在していない。
一般に、体力を向上させるとか、体のバランスを良くするという意味での機器は存在するようではあるが、事務作業をしている状態で、それを行う機器はない。
From the above, if you can sit and maintain the correct posture, even if you operate the computer for a long time, it seems that it is possible to avoid the posture getting worse and being attacked by significant fatigue, There is no such device.
In general, there seems to be a device that can improve physical fitness or improve the balance of the body, but there is no device that can do it while doing office work.
本発明は、上記のような問題点に鑑みてなされたものであり、その目的とするところは、座ったままの状態で、一定の範囲で椅子自体が、前後左右又は回転が自在となっており、姿勢をバランス良く保持しなければ、自動的に傾斜し、姿勢を正すことが求められる姿勢矯正用椅子を提供することを課題とする。 The present invention has been made in view of the above-described problems, and the object of the present invention is to allow the chair itself to freely rotate back and forth, right and left or within a certain range while sitting.

次に、本発明を、図を使用して具体的に説明する。なお、この説明は好適な一例を示すもので、本発明はこれらの実施例に限定されるものではない。したがって、本発明の技術思想に含まれる変形、他の実施例又は態様は、全て本発明に含まれる。 Next, the present invention will be specifically described with reference to the drawings. In addition, this description shows a suitable example and this invention is not limited to these Examples. Accordingly, all modifications and other examples or aspects included in the technical idea of the present invention are included in the present invention.
図１９に、本願発明の姿勢矯正用椅子４を使用した例を示す。この場合、椅子の上に本願発明の勢矯正用椅子４を載せ、作業者が机に向かってパソコンを操作している様子を示す。このように、本願発明の姿勢矯正用椅子４は小型にできているので、通常の椅子の上に載置することができる。
また、この図１９では、机に向かってパソコンの操作をしているが、そのまま座椅子としても、同様に使用することが可能である。その位の高さに調節されている。
FIG. 19 shows an example in which the posture correcting chair 4 of the present invention is used. In this case, the state correction chair 4 of the present invention is placed on the chair and the worker is operating the personal computer toward the desk. Thus, since the posture correction chair 4 of the present invention is made small, it can be placed on a normal chair.
In FIG. 19, the personal computer is operated toward the desk, but it can be used in the same manner as a sitting chair. The height is adjusted to that level.
図１に、本願発明の姿勢矯正用椅子４の正面図を示す。この図１に示すように、姿勢矯正用椅子４は、円形の台座１、リング状緩衝材２、座部３からなる。本願発明の姿勢矯正用椅子４の側面図を図２に、平面図を図３に、底面図を図４に示す。
このように、姿勢矯正用椅子４の前後は幅が小さく、横に長くなっており、人間が腰掛けるにおよそ適合する形になっている。しかし、この幅及び長さは、一定の機能を有する。
In FIG. 1, the front view of the chair 4 for posture correction of this invention is shown. As shown in FIG. 1, the posture correction chair 4 includes a circular pedestal 1, a ring-shaped cushioning material 2, and a seat portion 3. A side view of the posture correcting chair 4 of the present invention is shown in FIG. 2, a plan view is shown in FIG. 3, and a bottom view is shown in FIG.
As described above, the front and rear of the posture correcting chair 4 are small in width and long in the lateral direction, and are approximately adapted to a person sitting. However, this width and length have a certain function.
本願発明は、人間が腰掛けた状態で、無意識の内にバランスをとり、姿勢を最適な状態に維持することが目的である。
したがって、座り心地を良くするのではなく、姿勢を崩した場合に、それが自然に分かるように、むしろ不安定な状態に置くことが重要である。しかし、その不安定さにも限界があり、ピンポイントで支持するのは必ずしも良いとは限らない。この意味で、姿勢正しく腰掛けた場合には安定で、姿勢を悪くして座した場合には、やや安定性を欠き、姿勢を正すということが自然と行われるようにすることが重要である。
The object of the present invention is to maintain balance in an unconscious state while a human is seated and to maintain an optimal posture.
Therefore, it is important not to improve the sitting comfort, but rather to put it in an unstable state so that it can be understood naturally when the posture is lost. However, its instability is also limited, and pinpoint support is not always good. In this sense, it is important that the posture is stable when sitting correctly, and that when sitting with a poor posture, it is somewhat unstable and the posture is naturally corrected.
人間が腰掛けた状態で、自らの姿勢を制御する場合には、両足が前にあるので、前後については比較的容易に調節することができる。また、背の方は、図１９に示すように、通常の椅子には背もたれがあり、背もたれが無い場合でも敢えて後ろに反り返る仕草というのは伸びをする程度で、殆どないと言える。
このようなことから、専ら姿勢を制御する必要がある場合は、前かがみになる場合である。この場合は、強くバランスが崩れるのが好ましいと言える。このようなことから、前後の幅は小さい方が好ましい。一方、左右の動きについては、前記のような支持又は意識的に姿勢制御することは殆どないと言える。
When a person sits down and controls his / her posture, both feet are in front, so the front and back can be adjusted relatively easily. In addition, as shown in FIG. 19, it can be said that the normal chair has a backrest, and even if there is no backrest, the gesture that dares to warp back is an extent that it stretches, and it is almost impossible.
For this reason, when it is necessary to control the posture exclusively, it is a case where the user leans forward. In this case, it can be said that the balance is strongly lost. For this reason, it is preferable that the front-rear width is small. On the other hand, it can be said that there is almost no support or conscious posture control as described above for the left and right movements.
このため、注意すべきことは、多くの場合自然体と考えている本人が、体が傾斜していることがあることである。また、二本足で立っている場合よりも、座している方が、体が傾斜し易いと言える。このようなことから、姿勢矯正用椅子４の長さは、幅に比べて長い方が望ましい。しかし、姿勢矯正用椅子４の高さにもよるが、余り長いと傾斜角度が小さくなり、姿勢矯正用椅子４の機能が低下する。
以上について、この台座１の幅と長さは任意に調節可能ではあるが、多くのテストの結果、前記円形の台座１は、半径が８〜１５ｃｍの円盤であり、座部３は幅が１０〜１２ｃｍの楕円形を呈していることが最も好ましいことが分かった。本発明は、この点については、第２の発明の要件としている。
For this reason, it should be noted that in many cases, a person who considers a natural body may be inclined. Moreover, it can be said that the body is inclined more easily when sitting than when standing on two legs. For this reason, the length of the posture correcting chair 4 is preferably longer than the width. However, although depending on the height of the posture correcting chair 4, if the length is too long, the inclination angle becomes small, and the function of the posture correcting chair 4 is deteriorated.
Although the width and length of the pedestal 1 can be arbitrarily adjusted as described above, as a result of many tests, the circular pedestal 1 is a disk having a radius of 8 to 15 cm, and the seat 3 has a width of 10 It has been found most preferable to have an oval shape of ˜12 cm. The present invention makes this point a requirement of the second invention.
図５〜図８は、本願発明の姿勢矯正用椅子４の座部３の、正面図を図５に、右側面図を図６に、上面図を図７に、底面図を図８に示したものである。
座部３は、座面７と下面８を有しており、下面８の中心に先端が球体９となっているポール１０を有する。この先端が球体９になっているポール１０が、一定の重要な機能を有し、この姿勢矯正用椅子４に座った者が、姿勢をバランス良く保持しなければ、前後左右に傾き、場合によっては回転すら生ずる。このような状態では、例えばパソコン操作ができない。しかしながら、ほぼ姿勢を正すことができれば、安定した姿勢を維持でき、パソコン操作が可能となる。
5 to 8 show a front view, a right side view in FIG. 6, a top view in FIG. 7, and a bottom view in FIG. 8 of the seat 3 of the posture correcting chair 4 of the present invention. It is a thing.
The seat portion 3 has a seat surface 7 and a lower surface 8, and has a pole 10 whose tip is a sphere 9 at the center of the lower surface 8. The pole 10 whose tip is a sphere 9 has a certain important function. If a person sitting on the chair 4 for posture correction does not hold the posture in a well-balanced state, the pole 10 tilts forward, backward, left and right. Even rotation occurs. In such a state, for example, the personal computer cannot be operated. However, if the posture can be almost corrected, a stable posture can be maintained and the personal computer can be operated.
図９〜図１１は、本願発明の姿勢矯正用椅子４の台座１を示すもので、図９は上面図、図１０は正面図（又は側面図とも言える）、図１１は底面図である。この台座１は中心部に円形の凹陥部５を有する円盤状の突起部６からなる。
この台座１の凹陥部５に、前記ポール１０の球体９がゆるく嵌合する構造となっており、前後左右に傾き、場合によっては回転すら生ずる機能を備える重要な役目を持っている。すなわち、ポール１０の球体９は半径を１．５〜２．０ｃｍとし、台座１の凹陥部５は球体９よりもやや大きい１．７〜３．０ｃｍの球状の窪みが形成されている。
9 to 11 show the pedestal 1 of the posture correcting chair 4 of the present invention. FIG. 9 is a top view, FIG. 10 is a front view (or a side view), and FIG. 11 is a bottom view. The pedestal 1 is composed of a disc-shaped protrusion 6 having a circular recess 5 at the center.
The sphere 9 of the pole 10 is loosely fitted in the recessed portion 5 of the pedestal 1 and has an important role of having a function of tilting back and forth and right and left and even rotating in some cases. That is, the sphere 9 of the pole 10 has a radius of 1.5 to 2.0 cm, and the concave portion 5 of the base 1 is formed with a spherical depression of 1.7 to 3.0 cm that is slightly larger than the sphere 9.
このポール１０の球体９の半径と台座１の凹陥部５の球状の窪みとの関係は、一定の機能を有する。球体９の半径と台座１の凹陥部５の球状の窪みが同一の半径であるならば、座部３の下面８が単に傾斜するだけである。
しかし、図１８に示すように、台座１の凹陥部５は球体９よりもやや大きい球状の窪みを持つ場合には、例えば左に傾斜した場合には、図１８の図Ａに示すように、座部３の下面８が左にやや移動する。図１８の図Ｂは、それが移動しない場合である。
両者の対比から明らかなように、図１８の図Ｂの方はバランスをとり易い構造を持つが、図１８の図Ａの方、すなわち座部３の下面８が左にやや移動する場合は、バランスがより崩れやすいという機能を有している。これは、本願発明の目的に一致するものであり、さらに特異な機能を持つもので、第３の発明の構成要件としている。
The relationship between the radius of the sphere 9 of the pole 10 and the spherical depression of the recessed portion 5 of the pedestal 1 has a certain function. If the radius of the sphere 9 and the spherical recess of the recessed portion 5 of the pedestal 1 are the same radius, the lower surface 8 of the seat portion 3 simply tilts.
However, as shown in FIG. 18, when the recessed portion 5 of the base 1 has a spherical depression that is slightly larger than the sphere 9, for example, when tilted to the left, as shown in FIG. The lower surface 8 of the seat 3 moves slightly to the left. FIG. 18B shows a case where it does not move.
As apparent from the comparison between the two, FIG. 18B of FIG. 18 has a structure that is easier to balance, but in the case of FIG. 18A of FIG. It has a function that balance is more easily lost. This is consistent with the object of the present invention, has a more specific function, and is a constituent feature of the third invention.
さらに、台座１の凹陥部５に、複数の溝１１と中央に台座１の底面に貫通する貫通孔１２を備えている。この溝１１と貫通孔１２は、ポール１０の球体９と台座１は中心部に円形の凹陥部５との摩耗を減少させる効果があり、また貫通孔１２はごみが詰まった時の清掃に役に立つ効果を有する。
この溝１１と貫通孔１２は、本願発明の必須の要件ではないが、上記の特異な機能を有するものであり、必要に応じてこの構造を採用するのが望ましいと言える。
Further, the recessed portion 5 of the pedestal 1 is provided with a plurality of grooves 11 and a through hole 12 penetrating the bottom surface of the pedestal 1 at the center. The groove 11 and the through hole 12 have an effect of reducing wear of the spherical body 9 and the pedestal 1 of the pole 10 and the circular recessed portion 5 at the center, and the through hole 12 is useful for cleaning when the dirt is clogged. Has an effect.
The groove 11 and the through-hole 12 are not essential requirements of the present invention, but have the above-mentioned unique functions, and it can be said that it is desirable to adopt this structure as necessary.
本願発明については、簡便に取り扱いができる姿勢矯正用椅子４を提供することを目的の一つとしている。したがって、大型化、重量型にすることは、本願発明の目的には合致しない。多くのテストの結果、円形の台座１の下面と座部３の上面７との間隔を７〜１０ｃｍとし、ポール１０の高さが３．５〜５．５ｃｍとするのが最適である。この構造は、上記台座１、座部３、ポール１０の球体９、台座１の凹陥部５の構造から、必然的に決められる、最適な条件であり、これは第４の発明の構成要件としている。 An object of the present invention is to provide a posture correcting chair 4 that can be easily handled. Therefore, increasing the size and weight do not meet the object of the present invention. As a result of many tests, it is optimal that the distance between the lower surface of the circular pedestal 1 and the upper surface 7 of the seat portion 3 is 7 to 10 cm, and the height of the pole 10 is 3.5 to 5.5 cm. This structure is an optimum condition that is inevitably determined from the structure of the pedestal 1, the seat 3, the sphere 9 of the pole 10, and the recessed part 5 of the pedestal 1. This is a constituent requirement of the fourth invention. Yes.
さらに、本願発明の姿勢矯正用椅子４は、リング状緩衝材２を備える。この平面図を図１２に、側断面図を図１３に示す。このリング状緩衝材２は、非腰掛状態において、円形の台座１と座部３の座面７との平衡状態を維持するためのものである。腰掛ける際に傾斜していては、腰掛が非常に不便である。しかし、一旦、腰掛けた際には、前後左右又は回転による負荷時に傾くことが可能であり、負荷が開放された時点で、再度平衡を保持する柔軟性を備えた材料であることが望ましいと言える。
このリング状緩衝材２の材質は上記の機能が維持できれば、特に制限はないが、樹脂性のスポンジが好適である。また、摩耗や機能が維持できなくなった場合には、交換できるように、加工が容易でかつ安価な材料であることが望ましい。
Furthermore, the posture correcting chair 4 of the present invention includes a ring-shaped cushioning material 2. This plan view is shown in FIG. 12, and a side sectional view is shown in FIG. The ring-shaped cushioning material 2 is for maintaining an equilibrium state between the circular pedestal 1 and the seating surface 7 of the seat portion 3 in a non-sitting state. If the stool is tilted, the stool is very inconvenient. However, once seated, it is possible to incline at the time of front / rear / left / right or when a load is applied by rotation, and it is desirable that the material is flexible enough to maintain equilibrium again when the load is released. .
The material of the ring-shaped cushioning material 2 is not particularly limited as long as the above function can be maintained, but a resinous sponge is preferable. In addition, it is desirable that the material be easy to process and inexpensive so that it can be replaced when wear or function cannot be maintained.
本願発明の姿勢矯正用椅子４の、組立図における座部３の長い方の側断面図を図１４に示す。また、組立図における座部３の幅方向の側断面図を図１５に示す。また、姿勢矯正用椅子４の組立時の様子を示す図を、図１６に示す。
さらに、図１７に座部３が傾斜した場合の様子の断面図を示す。リング状スポンジなどリング状緩衝材２は、座部３の平衡を維持すると共に、台座１の上面と座部３の下面８との間に指や物を挟み込む事故を防ぐ役目をする。
FIG. 14 shows a side sectional view of the longer side of the seat portion 3 in the assembly drawing of the posture correcting chair 4 of the present invention. FIG. 15 is a side sectional view in the width direction of the seat portion 3 in the assembly drawing. Moreover, the figure which shows the mode at the time of the assembly of the chair 4 for posture correction is shown in FIG.
Further, FIG. 17 shows a cross-sectional view of the state in which the seat portion 3 is inclined. The ring-shaped cushioning material 2 such as a ring-shaped sponge maintains the balance of the seat portion 3 and serves to prevent an accident in which a finger or an object is caught between the upper surface of the base 1 and the lower surface 8 of the seat portion 3.
本願発明の姿勢矯正用椅子４の材質には、特に制限はない。しかし、軽量であること、重量がかかった場合の椅子としての丈夫さは必要である。このことから、軟質なリング状緩衝材２の材質を除き、木質材、アルミニウム又はその合金、チタン又はその合金、マグネシウム合金などの軽量金属材、さらには硬質樹脂材などが使用できる。これらの中で、加工が容易である木質材が好適な材料と言える。 There is no restriction | limiting in particular in the material of the chair 4 for posture correction of this invention. However, it is necessary to be lightweight and strong as a chair when heavy. From this, except for the material of the soft ring-shaped cushioning material 2, it is possible to use a wooden material, aluminum or an alloy thereof, a lightweight metal material such as titanium or an alloy thereof, a magnesium alloy, or a hard resin material. Among these, a wood material that can be easily processed can be said to be a suitable material.
本発明は、座ったままの状態で、椅子自体が一定の範囲で、前後左右又は回転が自在となっており、姿勢をバランス良く保持しなければ、自動的に傾斜し、姿勢を正すことが求められ、自動的に姿勢制御を行うことができるという優れた効果を有するので、姿勢矯正用椅子として有用である。 In the present invention, the chair itself can be freely moved back and forth, right and left, or rotated within a certain range while sitting down. Since it has an excellent effect of being required and automatically performing posture control, it is useful as a chair for posture correction.
