Description

【０００１】
【産業上の利用分野】
本発明は、椅子やソファ等の家具や、ベッドのマットレス等の寝具に内装されて使用される荷重受け面及びその弾性力調整方法に関するものである。ここで、本発明にいうところの家具並びに寝具とは上記の例示に限らず、電車や自動車に組付けられた座席等、身体からの荷重を受ける面を有するものを広く包含するものである。
【従来の技術】
【０００２】
例えば椅子やソファ等の家具や、ベッドのマットレス等の寝具におけるお尻や身体からの荷重（体重）を受けるマットや座部（荷重受け面）を形成するインナースプリング組立構造体は、図８に示すようにスプリング収納部１０５を平行に連続させた状態に複数の円筒形袋１０６を形成し、各円筒形袋１０６の夫々にコイルスプリング１０７をその軸心を平行に並べた状態で収納してインナースプリング列１０３を形成し、このインナースプリング列１０３をその側面同士が当接する状態に複数連結して形成してある。
【０００３】
上記従来の家具並びに寝具のマットや座部ではこのマットや座部を形成するインナースプリング列が全て同じ高さのものを組合せて構成されており、マットや座部を形成するインナースプリング列の全ては略均一に圧縮された状態で装着されている。したがって、例えばベッドのマットの場合、これに身体を横臥する時その荷重を略全てのインナースプリング列で受ける為にマットが非常に硬いものになってしまうという問題があった。
【０００４】
そこで、横臥する初期にはソフトに接し、全荷重を受ける時には確りと受けられるようにするために、例えばコイルスプリングのコイル径を上端部及び下端部で小径にして上端部分及び下端部分の弾性力を弱くしたり、上端部及び下端部のコイルピッチを細かくして上端部分及び下端部分の弾性力を弱くしたものがある。また、コイルスプリングを加工するのではなく、インナースプリング列の端部に厚めのウレタン、化繊綿、フェルト等のクッション材を置き、このクッション材の弾性で初期にはソフトに接し、全荷重を受ける時には確りと受けられるようにするようにしたものもある。
【０００５】
【発明が解決しようとする課題】
ところが、上記コイルスプリングのコイル径やコイルピッチを変更するようにしたものでは、コイルスプリングの製造に手間が掛かることから、生産性が低下するとともに、製造コストも高くなってしまうという問題があった。
【０００６】
また、厚めのウレタン、化繊綿、フェルト等のクッション材を用いるものでは斯かるクッション材のために大巾なコストアップとなるだけでなく、長期間の使用に対してウレタン、化繊綿、フェルト等のクッション材のへたりが早期に発生することから、耐久性にも問題があった。
【０００７】
更に、上記何れの構造並びに弾性力の調整方法でもマットの上下の面の弾力は同じ弾性力であることから、一定の弾性力のものとならざるを得ないという問題もあった。そこで、本発明は上記問題点に鑑み提案されたもので、家具並びに寝具のマットや座部等の荷重受け面の弾性力の調整幅が広く、更に、耐久性が高い荷重受け面を安価に製造することができるようにすること目的とするものである。
【０００８】
【課題を解決するための手段】
上記目的を達成するために本発明に係る家具並びに寝具の荷重受け面は、スプリング収納部を平行に連続させた状態に複数の収納袋を形成し、各収納袋の夫々にコイルスプリングをその軸心を平行に並べた状態で収納してなるインナースプリング列を、コイルスプリングの軸芯が平行になるように複数列連結してマット状に構成したインナースプリング組立構造体を形成し、インナースプリング組立構造体の表裏の少なくとも一方のインナースプリング列の端面の高さを異ならせた状態でインナースプリング列をその側面同士を当接させた状態で接合し、高さの低いインナースプリング列の少なくとも上方に空間が形成されるように配置して荷重受け面を形成したスプリング列をその側面同士を当接させた状態で接合して荷重受け面を形成したことを特徴とするものである。
【０００９】
また、家具並びに寝具の荷重受け面において、高さの異なる円筒形袋にスプリングを収納することにより、高さの異なるスプリング列を形成するようにしたことも特徴とするものである。
【００１０】
本発明に係る家具並びに寝具の荷重受け面の弾性力調整方法は、スプリング収納部を平行に連続させた複数の収納袋を形成し、各収納袋の夫々にコイルスプリングをその軸心を平行に並べた状態で収納してなるインナースプリング列を、コイルスプリングの軸芯が平行になるように複数列連結して荷重受け面を有するインナースプリング組立構造体を形成するとともに、複数のインナースプリング列の弾性力で荷重受け面の弾性力を形成するようにし、連結されるインナースプリング列の高さを異ならせることにより、高さの低いインナースプリング列の少なくとも上方に空間が形成されるように配置して少なくとも荷重が高さの異なる部分で受ける時と複数のインナースプリング列の全体で受ける時と荷重受け面の弾性力を変化させるようにしたことを特徴とするものである。
【００１１】
【発明の実施の形態】
以下、本発明に係る家具並びに寝具に装着されるインナースプリング組立構造体及びその製造方法を図に基づいて説明する。図１はベッドのマット部分に使用されるインナースプリング組立構造体の斜視図であって、図中符号１はこのインナースプリング組立構造体を全体的に示し、このインナースプリング組立構造体１の上面に荷重受け面２が形成されている。このインナースプリング組立構造体１は、図２に示す高さ（Ｈ１）の高いインナースプリング列３と、これよりも高さ（Ｈ２）の低いインナースプリング列４（図３参照）とをその側面同士を接着剤等で連結して構成されている。
【００１２】
本発明で使用するインナースプリング列の形成装置並びにインナースプリング組立構造体１の形成装置としては、本発明者が先に提案した特開平９−１７３６７３号（インナースプリング列の形成装置）及び特開平９−８５３７３号（インナースプリング組立構造体の製造装置）が用いられる。即ち、スプリング収納部５を平行に連続させた状態に複数の円筒形袋（収納袋）６を高さを異ならせて形成し、各円筒形袋６の夫々にコイルスプリング７をその軸心を平行に並べた状態で収納してインナースプリング列３・４を形成するようにしたものである。
【００１３】
上記のようにして形成された高さの異なるインナースプリング列３・４は、これを交互に配置し、当接する側面部分を接着剤（図示せず）等で連結すると、インナースプリング組立構造体１が形成される。この時、インナースプリング列３・４の配列は図４に示すように平面視においてインナースプリング列３・４のコイルスプリング７・７・７・・・同士が一点で当接すように列状に連結することもできるし、図５に示すように一方のインナースプリング列３・４のコイルスプリング７・７・７・・・間に他方のインナースプリング列３・４のコイルスプリング７・７・７・・・が位置するように千鳥状に配置することもできる。
【００１４】
そして、高さの異なるインナースプリング列３・４の側面視における取付位置は、図６に示すようにインナースプリング列３・４の下面を略面一（同一高さ）にして、高さの低いインナースプリング列４の上方に空間８が形成されるように配置する。斯くして形成された高さの異なるインナースプリング列３・４で形成されたインナースプリング組立構造体１では、これに身体の重量（荷重）が作用した場合、まず、高さの高いインナースプリング列３・３・３・・・でその荷重を受けるのでその弾性力は柔らかなものとなる。
【００１５】
次に、高さの高いインナースプリング列３・３・３・・・が縮んで高さの低いインナースプリング列４・４・４・・・の上方の空間８が無くなると、身体の重量（荷重）は両インナースプリング列３・４で支えられるためにその弾性力は硬いものとなる。また、高さの異なるインナースプリング列３・４の側面視における取付位置としては上述したようにインナースプリング列３・４の下面を略面一（同一高さ）にしたものの他、図７に示すようにインナースプリング列３・４の各中心９・９・９・・・の位置を略同一高さにして高さの低いインナースプリング列４の上方及び下方に夫々空間８・８を形成するようにする。
【００１６】
こうしたものでは下方のインナースプリング組立構造体１の重量で下方の空間部分８が縮んでおり、身体の重量（荷重）が作用した場合、下方の空間８部分がまず縮んだ後、上方の空間８部分が縮み、然る後、身体の重量（荷重）は両インナースプリング列３・４で支えられるので弾性力は三段階に変化することになる。更に、上述の高さが低いインナースプリング列４・４・４・・・の上下に夫々空間８・８を形成するにあたり、空間の高さを、例えば上側の空間を大きくしたり、逆に下側の空間を大きくするようにしても良く、こうしたものではさらに、身体の重量（荷重）の受け方が変化する。
【００１７】
つまり、空間を大きくすると弾性力が柔らかく、沈み込みが大きくなり、身体の凹凸に沿いやすく、フィット感がよくなる。また、こうした場合、インナースプリング組立構造体１を上下（表裏）を反転させて使用することにより、弾性力を変化させることもできる。尚、上記実施の形態では高さの異なるインナースプリング列３・４を交互に配置するようにしてあるが、こうしたものに限られず、高さの異なるインナースプリング列３・４を所定本数置きに配置して弾性力の調整を行うようにすることができるのは勿論のことである。
【００１８】
【発明の効果】
本発明は以上に説明したように、インナースプリング列を複数列連結してマット状の荷重受け面を形成するにあたり、連結されるインナースプリング列の高さを異ならせて荷重受け面を形成するインナースプリング列が荷重を受ける時期をずらすことにより、荷重受け面の弾性力を変化させるようにしてあるので、従来のように、個々のコイルスプリングのコイル径やコイルピッチを変更して荷重受け面の弾性力を変化させるようにしたものに比べてコイルスプリングの製造に手間がかからず、生産性が向上し大量生産による製造コストを低減することができる利点がある。
【００１９】
また、連結されるインナースプリング列の高さを異ならせて荷重受け面の弾性力を変化させるようにしてあるので、例えば厚めのウレタン、化繊綿、フェルト等のクッション材を用いるようにした従来のものに比べてクッション材によるコストアップを防止できるとともに、クッション材のへたりがなく、耐久性を大幅に向上させることができるという利点もある。
【００２０】
更に、マット状の荷重受け面の表面と裏面を形成するインナースプリング列の高さの差を異ならせると、表面と裏面とではその弾性力も異ならせることができ、弾性力の調整幅を広くして荷重の種類や好みにも広く対応することができるという利点もある。

[Industrial application fields]
The present invention relates to a load receiving surface used in furniture such as a chair and a sofa, and bedding such as a mattress of a bed, and a method for adjusting the elastic force thereof. Here, the furniture and bedding referred to in the present invention are not limited to the above examples, and widely include those having a surface that receives a load from the body, such as a seat assembled in a train or an automobile.
[Prior art]
[0002]
For example, FIG. 8 shows an inner spring assembly structure that forms a mat and a seat (load receiving surface) that receive a load (weight) from the hips and the body in furniture such as a chair and a sofa, and bedclothes such as a bed mattress. As shown, a plurality of cylindrical bags 106 are formed in a state in which the spring storage portions 105 are connected in parallel, and a coil spring 107 is stored in each cylindrical bag 106 in a state where its axis is aligned in parallel. An inner spring row 103 is formed, and a plurality of inner spring rows 103 are connected in such a manner that their side surfaces are in contact with each other.
[0003]
In the conventional furniture and bedding mats and seats, the inner spring rows that form the mats and seats are all combined in the same height, and all the inner spring rows that form the mats and seats. Is mounted in a substantially uniformly compressed state. Therefore, for example, in the case of a mat for a bed, there is a problem that the mat becomes very hard because the load is received by almost all the inner spring rows when lying down on the body.
[0004]
Therefore, in order to be able to receive softly when receiving a full load in the initial stage of lying down, for example, the coil diameter of the coil spring is made small at the upper end and lower end, and the elastic force of the upper end and lower end is reduced. Or the coil pitch at the upper end and the lower end is made fine to reduce the elastic force at the upper end and the lower end. Also, instead of processing the coil spring, a cushion material such as thick urethane, synthetic cotton or felt is placed at the end of the inner spring row, and the elasticity of this cushion material makes initial contact with the soft and receives the full load. Some are designed to be surely received.
[0005]
[Problems to be solved by the invention]
However, in the case of changing the coil diameter and coil pitch of the coil spring, it takes time to manufacture the coil spring, so that there is a problem that productivity is lowered and manufacturing cost is also increased. .
[0006]
In addition, using cushion materials such as thick urethane, synthetic cotton, felt, etc. not only greatly increases the cost for such cushion material, but also urethane, synthetic cotton, felt, etc. for long-term use. Since the sag of the cushion material was generated at an early stage, there was a problem in durability.
[0007]
Further, in any of the above structures and methods for adjusting the elastic force, the elasticity of the upper and lower surfaces of the mat is the same elastic force, so that there is a problem that the elastic force has to be constant. Accordingly, the present invention has been proposed in view of the above problems, and the adjustment range of the elastic force of the load receiving surface such as the mat and the seat of furniture and bedding is wide, and furthermore, a highly durable load receiving surface is inexpensive. It is intended to be able to be manufactured.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the load receiving surfaces of furniture and bedding according to the present invention form a plurality of storage bags in a state in which the spring storage portions are continuous in parallel, and coil springs are respectively attached to the respective storage bags. Inner spring assembly is made by connecting multiple inner spring rows that are housed in a state where the cores are arranged in parallel to form a mat shape by connecting multiple rows so that the axis of the coil spring is parallel. Join the inner spring rows with their side surfaces in contact with each other with the height of the end faces of at least one inner spring row on the front and back of the structure being different, and at least above the lower inner spring row by joining the spring columns forming the load bearing surface positioned to so as to space formed being in contact with the side faces forming a load bearing surface It is characterized in.
[0009]
Moreover, the springs having different heights are formed by housing the springs in cylindrical bags having different heights on the load receiving surfaces of the furniture and the bedding.
[0010]
The method for adjusting the elastic force of the load receiving surface of the furniture and the bedding according to the present invention includes forming a plurality of storage bags in which the spring storage portions are connected in parallel, and coil springs in each of the storage bags in parallel with the axis. A plurality of inner spring rows that are housed in an aligned state are connected so that the axial centers of the coil springs are parallel to form an inner spring assembly structure having a load receiving surface. The elastic force of the load receiving surface is formed by the elastic force, and the height of the connected inner spring rows is made different so that a space is formed at least above the lower inner spring row. at least as load to vary the elastic force when the load receiving surface for receiving the whole of a plurality of innerspring row and when received by different parts of heights Te It is characterized in that the.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an inner spring assembly structure mounted on furniture and bedding according to the present invention and a manufacturing method thereof will be described with reference to the drawings. FIG. 1 is a perspective view of an inner spring assembly structure used for a mat portion of a bed. In FIG. 1, reference numeral 1 generally indicates the inner spring assembly structure. A load receiving surface 2 is formed. The inner spring assembly structure 1 includes an inner spring row 3 having a high height (H1) and an inner spring row 4 having a lower height (H2) (see FIG. 3) shown in FIG. Are connected with an adhesive or the like.
[0012]
As an inner spring row forming apparatus and an inner spring assembly structure 1 forming apparatus used in the present invention, Japanese Patent Laid-Open No. 9-173673 (inner spring row forming apparatus) and Japanese Patent Laid-Open No. -85373 (manufacturing apparatus for inner spring assembly structure) is used. That is, a plurality of cylindrical bags (storage bags) 6 are formed with different heights in a state in which the spring storage portions 5 are continuous in parallel, and the coil springs 7 are axially centered on each cylindrical bag 6. The inner spring rows 3 and 4 are formed by being housed in parallel.
[0013]
The inner spring rows 3 and 4 having different heights formed as described above are arranged alternately, and the side portions that come into contact with each other are connected with an adhesive (not shown) or the like, so that the inner spring assembly structure 1 Is formed. At this time, as shown in FIG. 4, the inner spring rows 3 and 4 are arranged in a row so that the coil springs 7, 7,... As shown in FIG. 5, the coil springs 7, 7, 7 of the other inner spring row 3, 4 are interposed between the coil springs 7, 7, 7. It can also be arranged in a staggered pattern so that.
[0014]
And, as shown in FIG. 6, the mounting positions of the inner spring rows 3 and 4 having different heights in a side view are low, with the lower surfaces of the inner spring rows 3 and 4 being substantially flush (same height). The space 8 is disposed above the inner spring row 4. In the inner spring assembly structure 1 formed by the inner spring rows 3 and 4 having different heights formed in this way, when a body weight (load) is applied to the inner spring row structure, first, the inner spring row having a high height is formed. Since the load is received at 3, 3, 3..., The elastic force is soft.
[0015]
Next, when the inner spring rows 3, 3, 3... Are shrunk and the space 8 above the lower inner spring rows 4, 4, 4. ) Is supported by both inner spring rows 3 and 4, and therefore its elastic force is hard. Further, as described above, the inner spring rows 3 and 4 having different heights in the side view are shown in FIG. 7 in addition to those in which the lower surfaces of the inner spring rows 3 and 4 are substantially flush (same height) as described above. As described above, the positions of the centers 9, 9, 9... Of the inner spring rows 3 and 4 are made substantially the same height so that spaces 8 and 8 are formed above and below the lower inner spring row 4 respectively. To.
[0016]
In such a case, the lower space portion 8 is contracted by the weight of the lower inner spring assembly structure 1, and when the body weight (load) is applied, the lower space 8 portion is first contracted, and then the upper space 8 is compressed. The portion shrinks, and then the weight (load) of the body is supported by both inner spring rows 3 and 4, so that the elastic force changes in three stages. Further, when forming the spaces 8 and 8 above and below the inner spring rows 4, 4, 4... Having a low height, the height of the space is increased, for example, the upper space is increased or vice versa. The space on the side may be enlarged, and in such a case, how to receive the weight (load) of the body changes.
[0017]
In other words, the larger the space, the softer the elastic force, the greater the sinking, the easier it is to follow the unevenness of the body, and the better the fit. In such a case, the elastic force can be changed by using the inner spring assembly structure 1 with the upper and lower sides (front and back) reversed. In the above embodiment, the inner spring rows 3 and 4 having different heights are alternately arranged. However, the present invention is not limited to this, and the inner spring rows 3 and 4 having different heights are arranged every predetermined number. Of course, the elastic force can be adjusted.
[0018]
【The invention's effect】
As described above, in the present invention, when a plurality of inner spring rows are connected to form a mat-shaped load receiving surface, the inner spring rows to be connected are formed at different heights to form the load receiving surface. Since the elastic force of the load receiving surface is changed by shifting the time when the spring train receives the load, the coil diameter and coil pitch of each coil spring is changed as in the past, and the load receiving surface is changed. Compared with the one in which the elastic force is changed, it takes less time to manufacture the coil spring, and there is an advantage that productivity can be improved and manufacturing cost by mass production can be reduced.
[0019]
In addition, since the elastic force of the load receiving surface is changed by changing the height of the connected inner spring row, for example, a conventional cushion material such as thick urethane, synthetic cotton, felt or the like is used. There is an advantage that the cost increase due to the cushioning material can be prevented as compared with the thing, and there is no sag of the cushioning material, and the durability can be greatly improved.
[0020]
Furthermore, if the height difference between the inner spring rows forming the front and back surfaces of the mat-shaped load receiving surface is made different, the elastic force can be made different between the front and back surfaces, and the adjustment range of the elastic force is widened. There is also an advantage that it can cope with a wide variety of loads and preferences.
