Description

本発明は、マットレス、寝台、椅子の座部や背凭れ、枕などに利用されるクッション台に関する。 The present invention relates to a cushion base used for a mattress, a bed, a chair seat, a backrest, a pillow, and the like.

この種のクッション台としては、例えば特許文献１に示すように、コイルスプリングを収容した多数の筒状の袋体を立設配置し、これら袋体を上下から厚みのあるポリエステル樹脂ファイバ製やその他の樹脂ファイバなどからなる上部弾性材と柔軟性の大きいウレタンフォームなどからなる下部弾性材で挟んだマットレス装置が知られている。しかし、このマットレス装置は、コイルスプリング自体の径が大きくなっており、さらにコイルスプリングの上に厚みの厚い上部弾性材がある構造であり、その上に仰向けに横たわった体全体を受け止めるように大まかに変形するようになっている。そのため、このマットレス装置では、体の臀部等の突出した部分とその間の凹んだ部分に応じた細かい変形が行われるというものではない。その結果、上記マットレス装置の上面と体の凹凸部分の当りが均等にはならなくなることにより、体に加わる負荷が大きくなるため、快適な寝心地が妨げられるおそれがある。 As this type of cushion base, for example, as shown in Patent Document 1, a large number of cylindrical bag bodies containing coil springs are arranged upright, and these bag bodies are made of polyester resin fiber having a thickness from above and below, and others. A mattress device is known which is sandwiched between an upper elastic material made of resin fiber or the like and a lower elastic material made of highly flexible urethane foam or the like. However, this mattress device has a structure in which the diameter of the coil spring itself is large, and there is a thick upper elastic material on the coil spring, and it is roughly so as to receive the entire body lying on its back on it. It is supposed to be deformed. For this reason, in this mattress device, a fine deformation according to the protruding part such as a buttock of the body and the recessed part between them is not performed. As a result, since the contact between the upper surface of the mattress device and the uneven portion of the body is not uniform, the load applied to the body is increased, and there is a possibility that comfortable sleeping comfort may be hindered.

本発明は、上記問題を解決しようとするもので、体を預けたときに体の面に合わせてスムーズに変形すると共に、適度な反発力も備えた長期にわたって安定した性能を維持できるクッション台を提供することを目的とする。 The present invention is intended to solve the above problem, and provides a cushion base that can be deformed smoothly in accordance with the surface of the body when the body is deposited, and can maintain stable performance over a long period of time with an appropriate repulsive force. The purpose is to do.

上記目的を達成するために、本発明の構成上の特徴は、長方形の厚板の全面に厚さ方向に貫通して高密度で配置された多数の挿通孔を有するベース板と、ベース板の周縁側に取り付けられて、ベース板を支持する支持台と、挿通孔に摺動自在に挿通されて、ベース板の表面側の端部が山状に尖った当接端部になっており、裏面側の端部が止め部になっており、当接端部と止め部によって挿通孔から抜け止めされた複数のピン部材と、ベース板の表面側にてピン部材の外周側に同軸状に嵌め合わされて当接端部とベース板の挿通孔周囲に当接して、ピン部材を当接端部方向に付勢する共に、ピン部材の裏面側への突出長さを一定以下に規制するコイルばね材と、ピン部材の当接端部側全体に被せられた弾性変形可能な薄い上面カバーと、を設けたことにある。 In order to achieve the above object, the structural feature of the present invention is that a base plate having a large number of insertion holes arranged in a high density through the entire thickness of a rectangular thick plate, and the base plate It is attached to the peripheral side, is slidably inserted into the support base that supports the base plate, and the insertion hole, and the end on the surface side of the base plate is a contact end pointed in a mountain shape, The end on the back side is a stop, and a plurality of pin members that are prevented from coming off from the insertion hole by the contact end and the stop, and coaxially on the outer peripheral side of the pin member on the surface side of the base plate A coil that is fitted and abuts the abutting end portion and the periphery of the insertion hole of the base plate to urge the pin member toward the abutting end portion, and regulates the protruding length of the pin member to the back surface side below a certain level. Provided with a spring material and a thin top cover that can be elastically deformed over the entire contact end side of the pin member It lies in the fact.

上記のように構成した本発明においては、クッション台の表面側に体を預けることにより、薄い上面カバーを介して高密度で配置されたピン部材の当接端部に体が当たり、ピン部材がコイルばね材によって付勢されて上下に変位する。多数のコイルばね材が、クッション台に接触する体の凹凸部分に応じて適正に弾性変形することにより、多数のピン部材の他端側がベース板の裏面側に突出し、またその反発力により表面側に戻ろうとする。その結果、本発明においては、体の凹凸状態に応じてクッション台表面が適正に変形するため、体が適正な状態でクッション台に受け止められて、快適な休息状態が確保される。また、コイルばね材が収縮しきった状態でピン部材の変形が止められるため、体の過大な変形も確実に止められる。さらに、ピン部材が沈みきった箇所では、その部分のピン部材の山状の当接端部が体に強く当たることにより、指圧効果も得られる。 In the present invention configured as described above, by depositing the body on the surface side of the cushion base, the body hits the contact end portion of the pin member arranged at high density via the thin top cover, and the pin member It is biased by the coil spring material and displaced up and down. A large number of coil spring materials appropriately elastically deform according to the uneven part of the body that contacts the cushion base, so that the other end side of the numerous pin members protrudes on the back side of the base plate, and the repulsive force causes the surface side Trying to return. As a result, in the present invention, the cushion base surface is appropriately deformed according to the uneven state of the body, so that the body is received by the cushion base in an appropriate state, and a comfortable resting state is ensured. Further, since the deformation of the pin member is stopped in a state where the coil spring material is completely contracted, excessive deformation of the body can be reliably stopped. Further, at the location where the pin member has fully sunk, the mountain-shaped abutting end of the pin member strongly hits the body, so that a shiatsu effect is also obtained.

本発明の他の特徴は、長方形の厚板の全面に厚さ方向に貫通して高密度で配置された多数の挿通孔を有するベース板と、ベース板の周縁側に取り付けられて、ベース板を支持する支持台と、挿通孔に摺動自在に挿通されて、ベース板の表面側の端部が山状に尖った当接端部になっており、裏面側の端部が止め部になっており、当接端部と止め部によって挿通孔から抜け止めされた複数のピン部材と、ベース板の裏面側にてピン部材の外周側に同軸状に嵌め合わされて、両端が止め部とベース板の挿通孔周囲に固定されて、ピン部材を当接端部方向に付勢するコイルばね材と、ピン部材の当接端部側全体に被せられた弾性変形可能な薄い上面カバーと、を設けたことにある。 Another feature of the present invention is that a base plate having a large number of insertion holes arranged at high density through the entire thickness of a rectangular thick plate, and attached to the peripheral side of the base plate, The base plate is slidably inserted in the insertion hole, the end on the front side of the base plate is a pointed contact end, and the end on the back side is the stop A plurality of pin members that are prevented from coming off from the insertion holes by the abutting end portions and the stopper portions, and fitted on the outer peripheral side of the pin member on the back surface side of the base plate in a coaxial manner, with both ends being the stopper portions. A coil spring material fixed around the insertion hole of the base plate and biasing the pin member in the direction of the abutting end; and a thin top cover that is elastically deformable over the entire abutting end side of the pin member; It is in having established.

他の特徴においては、クッション台に接触する体の凹凸部分に応じて、ベース板の下方に設けたコイルばね材が上方にコイルばね材を設けた場合と同様に適正に弾性変形することにより、高密度で配置された多数のピン部材の他端側がベース板の裏面側に突出し、また表面側に戻ろうとするように適正に弾性変形する。その結果、他の特徴においても、上述したと同様に、体の凹凸状態に応じてクッション台表面が適正に変形するため、体が適正な状態でクッション台に受け止められ、快適な休息状態が確保される。 In other features, the coil spring material provided below the base plate is appropriately elastically deformed in the same manner as when the coil spring material is provided above in accordance with the uneven portion of the body contacting the cushion base, The other end side of many pin members arranged at high density protrudes to the back side of the base plate, and is appropriately elastically deformed so as to return to the front side. As a result, in the other features as well, as described above, the cushion base surface is appropriately deformed according to the uneven state of the body, so that the body is received by the cushion base in an appropriate state and a comfortable resting state is ensured. Is done.

また、本発明において、多数の挿通孔が、ベース板の縦横方向に沿って等間隔で配置されて複数列にされており、さらに互いに隣接する列にある挿通孔同士は４５°ずれた位置に交互に配置されていることが好ましい。このように挿通孔同士を４５°ずれた位置に交互に配置することにより、クッション台に当接する体の複雑な凹凸状態に応じてピン部材の上下変動がより適正に行われ、上述したようなクッション台による体を受け止める作用効果がより適正に発揮される。 Further, in the present invention, a large number of insertion holes are arranged at equal intervals along the vertical and horizontal directions of the base plate to form a plurality of rows, and the insertion holes in the rows adjacent to each other are shifted by 45 °. It is preferable that they are arranged alternately. By alternately arranging the insertion holes at positions shifted by 45 ° in this way, the vertical movement of the pin member is more appropriately performed according to the complex uneven state of the body that contacts the cushion base, as described above. The effect of receiving the body by the cushion base is more appropriately exhibited.

また、本発明において、コイルばね材の弾性力の大きさを、ベース板の場所によって変更可能にすることができる。これにより、クッション台を使用する使用者の体の状態に応じてコイルばね材の弾性力の大きさを調節できるため、使用者に応じた適正なクッション台を提供できる。 In the present invention, the magnitude of the elastic force of the coil spring material can be changed depending on the location of the base plate. Thereby, since the magnitude | size of the elastic force of a coil spring material can be adjusted according to the state of the user's body which uses a cushion stand, the appropriate cushion stand according to a user can be provided.

また、本発明において、ベース板内の複数個所にてベース板に取り付けられて裏面側に延びた支持台と共にベース板を補強する補強部材を設けることができる。これにより、面積の広いベース板が、周縁側の支持台に加えて内側の複数個所にて補強部材によって補強されるため、重い重量の体を支え続けてもベース板の変形が抑えられて長期の使用が可能になる。 Moreover, in this invention, the reinforcement member which reinforces a base board with the support stand attached to the base board in the several places in a base board, and extended to the back surface side can be provided. As a result, the base plate with a large area is reinforced by the reinforcing members at a plurality of locations on the inner side in addition to the support table on the peripheral side. Can be used.

また、本発明において、ピン部材を樹脂製とすることができる。これにより、金属等の他の材料に比べて多数のピン部材の材料コストを安価にできると共に、量産もよいため、ピン部材の価格を安価にでき、その結果、クッション台の価格も安価にできる。また、多数のピン部材を軽量化できるため、クッション台全体も大幅に軽量化できる。 In the present invention, the pin member can be made of resin. As a result, the material cost of a large number of pin members can be reduced compared to other materials such as metal, and the mass production is good, so the price of the pin members can be reduced, and as a result, the price of the cushion base can also be reduced. . Moreover, since many pin members can be reduced in weight, the cushion base as a whole can also be significantly reduced in weight.

また、本発明において、支持台のベース板の裏面側内の空間全体が、弾性支持材で充填されてもよい。これにより、ピン部材が表面側でコイルばね材によって支持されると共に、裏面側で弾性支持材でも受け止められるため、ピン部材の上下変動の一層なめらかさが得られ、クッション台への体の接触状態がさらに滑らかにされる。 Moreover, in this invention, the whole space in the back surface side of the base plate of a support stand may be filled with an elastic support material. As a result, the pin member is supported by the coil spring material on the front surface side and is also received by the elastic support material on the back surface side, so that a smoother vertical movement of the pin member is obtained, and the body contact state with the cushion base Is even smoother.

本発明においては、クッション台の表面側に体を預けることにより、薄い上面カバーを介して高密度で配置されたピン部材の当接端部に体が当たり、ピン部材がコイルばね材の弾性変形によって付勢されて上下に変位する。その結果、本発明においては、体の凹凸状態に応じてクッション台表面が適正に変形するため、体が適正な状態でクッション台に受け止められ、快適な休息状態が確保される。また、本発明によれば、コイルばね材が収縮しきった状態でピン部材の変形が止められるため、体の過大な変形も確実に止められ、さらに、ピン部材が沈みきった箇所では、その部分のピン部材の凸曲面状の頭部が体に強く当たることによる指圧効果も得られる。 In the present invention, by placing the body on the surface side of the cushion base, the body hits the contact end portion of the pin member arranged at high density via the thin top cover, and the pin member is elastically deformed by the coil spring material. It is energized by and displaces up and down. As a result, in the present invention, the cushion base surface is appropriately deformed according to the uneven state of the body, so that the body is received by the cushion base in an appropriate state, and a comfortable resting state is ensured. In addition, according to the present invention, since the deformation of the pin member is stopped in a state where the coil spring material is fully contracted, excessive deformation of the body is also reliably stopped. An acupressure effect is also obtained when the convexly curved head of the pin member strongly hits the body.

It is shown by.

寝台１０は、長方形の木製の厚板であるベース板１１を有している。ベース板１１は、その全面に厚さ方向に貫通して高密度で配設された多数の挿通孔１２を有している。複数の挿通孔１２は、ベース板１１の幅方向（図２の上下方向）の両端間に中心間が一定の間隔ｔで配列されて縦列Ｐｋ（ｋ＝１〜ｎ）をなしている。縦列Ｐｋは、長手方向の両端間に中心間が一定の間隔ｔ／２でｎ本配列されている。縦列Ｐｋのうち、図１に示す長手方向の両側を含めた奇数列が幅方向の配置も揃えられており、偶数列が奇数列に対して幅方向にｔ／２ずつずれており、幅方向の両側に１個ずつはみ出している。即ち、偶数列と奇数列の挿通孔１２はベース板１１の長手方向に対して互いに４５°斜めにずれた位置に配置された関係になっている。なお、この縦列Ｐｋの関係については、これと直角の横列についてみても同様の関係となっている。 The bed 10 has a base plate 11 which is a rectangular wooden plank. The base plate 11 has a large number of insertion holes 12 penetrating in the thickness direction and arranged at high density on the entire surface. The plurality of insertion holes 12 are arranged at regular intervals t between both ends of the base plate 11 in the width direction (vertical direction in FIG. 2) to form a column Pk (k = 1 to n). In the column Pk, n lines are arranged between the ends in the longitudinal direction with a constant interval t / 2 between the centers. Of the columns Pk, the odd columns including both sides in the longitudinal direction shown in FIG. 1 are arranged in the width direction, and the even columns are shifted by t / 2 in the width direction with respect to the odd columns. One sticks out on both sides. That is, the insertion holes 12 in the even-numbered rows and the odd-numbered rows have a relationship of being disposed at positions that are obliquely shifted from each other by 45 ° with respect to the longitudinal direction of the base plate 11. Note that the relationship between the columns Pk is similar even when viewed at a right-angled row.

各挿通孔１２には、ピン部材１４が挿通孔１２との間にわずかの隙間を保って摺動自在に挿通されている。ピン部材１４は、図５に示すように、樹脂製のボルト１５とその先端に螺着される当接端部である円盤状の当接部材１６とを設けている。ボルト１５は、基部の一端が半球形状の頭部１５ａで、他端側がねじ溝１５ｂになっている。ボルト１５の基部外径は２〜１０ｍｍの範囲である。基部外径が２ｍｍより小さいとボルト１５の十分な強度が確保されず、また１０ｍｍより大きいと重量が大きくなりすぎる。当接部材１６は、円盤状の一表面側が山状に膨らんだ円盤部１７と、その軸方向内側に同軸状に取り付けられた短い軸部１８とを一体で設けており、軸部１８の中心に軸方向に貫通したねじ穴１８ａを設けており、ねじ穴１８ａにボルト１５がねじ溝１５ｂにて螺着されている。ピン部材１４は、ボルト１５をベース板１１の下側から挿通孔１２に差し込んで、突出したねじ溝１５ｂに当接部材１６を螺着することによりベース板１１に取り付けられる。 A pin member 14 is slidably inserted into each insertion hole 12 with a slight gap between the pin member 14 and the insertion hole 12. As shown in FIG. 5, the pin member 14 is provided with a resin bolt 15 and a disk-like contact member 16 which is a contact end portion screwed to the tip thereof. The bolt 15 has a hemispherical head 15a at one end of the base and a thread groove 15b at the other end. The base outer diameter of the bolt 15 is in the range of 2 to 10 mm. If the outer diameter of the base is smaller than 2 mm, sufficient strength of the bolt 15 is not ensured, and if it is larger than 10 mm, the weight becomes too large. The abutting member 16 is integrally provided with a disk portion 17 having a disk-shaped one surface side swelled in a mountain shape and a short shaft portion 18 that is coaxially attached to the inner side in the axial direction. A screw hole 18a penetrating in the axial direction is provided, and a bolt 15 is screwed into the screw hole 18a with a screw groove 15b. The pin member 14 is attached to the base plate 11 by inserting the bolt 15 into the insertion hole 12 from the lower side of the base plate 11 and screwing the contact member 16 into the protruding screw groove 15b.

当接部材１６の外径は１０〜３５ｍｍである。外径が１０ｍｍより小さいと体に対する当りが強くなりすぎ、また３５ｍｍより大きくなると大きすぎて体の凹凸の変化に応じた追従が困難になる。ボルト１５にはゴム弾性体製の円環状薄板である一対の緩衝板材１９が中心孔にて緊密状態で挿嵌されており、頭部１５ａに当接した状態で配設されている。上述した挿通孔１２間の間隔ｔについては、当接部材１６の外径に応じて決められ、隣接する当接部材１６が重なり合わないように、また離れすぎないように適宜決められる。以上のように、ピン部材１４は、ベース板１１の全面に従来の寝台にはない非常な高密度で配設される。 The outer diameter of the contact member 16 is 10 to 35 mm. When the outer diameter is smaller than 10 mm, the contact with the body becomes too strong, and when it is larger than 35 mm, it is too large and it becomes difficult to follow the change in the unevenness of the body. A pair of shock-absorbing plate materials 19 which are annular thin plates made of a rubber elastic body are inserted into the bolts 15 in a tight state at the center hole, and are arranged in contact with the head portion 15a. The interval t between the insertion holes 12 described above is determined according to the outer diameter of the contact member 16, and is determined as appropriate so that adjacent contact members 16 do not overlap and are not separated too much. As described above, the pin members 14 are disposed on the entire surface of the base plate 11 at a very high density that is not found in a conventional bed.

ボルト１５のベース板１１上面から突出した部分には、コイルばね材２１が伸縮自在に巻装されており、長手方向の両端が当接部材１６とベース板１１上面に当接している。これにより、コイルばね材２１は、図３の奇数列に示すように、その弾性力によってピン部材１４を上方に向けて付勢しており、ピン部材１４は上方に向けて持ち上げられ、ボルト１５の頭部１５ａが、ベース板１１の下面側に緩衝板材１９を介して当接した状態になっている。コイルばね材２１の長さは３０〜１５０ｍｍである。長さが３０ｍｍより小さいと体の凹凸状態に対応しきれなく、また１５０ｍｍより大きいと体の沈み込みが大きくなりすぎて不安定になる。また、コイルばね材２１は収縮による最短長さが１０〜５０ｍｍであり、図４の偶数列に示すように、収縮しきった状態がピン部材１４の下降限界となり、全体長さに応じたものである。コイルばね材２１の両端側表面には、当接部材１６及びベース板１１との緩衝のためにゴム材がコーティングされている。 A coil spring material 21 is stretchably wound around a portion of the bolt 15 protruding from the upper surface of the base plate 11, and both ends in the longitudinal direction are in contact with the contact member 16 and the upper surface of the base plate 11. As a result, the coil spring material 21 urges the pin member 14 upward by its elastic force, as shown in the odd-numbered rows in FIG. 3. The pin member 14 is lifted upward, and the bolt 15 The head portion 15 a is in contact with the lower surface side of the base plate 11 via the buffer plate material 19. The length of the coil spring material 21 is 30 to 150 mm. If the length is less than 30 mm, it cannot fully cope with the uneven state of the body, and if it is more than 150 mm, the body sinks too much and becomes unstable. Further, the coil spring material 21 has a minimum length of 10 to 50 mm due to contraction, and as shown in the even-numbered rows in FIG. 4, the contracted state becomes the lower limit of the pin member 14 and corresponds to the overall length. is there. A rubber material is coated on both end surfaces of the coil spring material 21 for buffering the contact member 16 and the base plate 11.

ベース板１１下面の周縁には長方形の木製の枠部材２２が固定されている。枠部材２２は、図４に示すように、下端がピン部材１４の下降限界位置での下端よりわずかに長くなっている。枠部材２２の下端には、枠部材２２と共に支持台を構成する木製の底板２３が取り付けられている。ただし、必要に応じて底板を省くことも可能である。ピン部材１４がコイルばね材２１に付勢されて伸びきった状態の頭部上端全体には、柔軟な繊維製の薄い上面カバー２４が被せられており、その周縁がベース板１１の側部に被せて固定されている。また、ベース板１１内の予め規定した複数個所には、図６に示すように、ねじ溝を有する取付孔１３がベース板１１を貫通して設けられており、取付孔１３には補強部材２５が取り付けられている。補強部材２５は、丸棒２６の先端側にねじ２７を有するボルトであり、ベース板１１の下面側から取付孔１３に高さ調節可能に螺合されており、頭部２８が底板２３に接触した状態で取り付けられている。 A rectangular wooden frame member 22 is fixed to the periphery of the lower surface of the base plate 11. As shown in FIG. 4, the lower end of the frame member 22 is slightly longer than the lower end of the pin member 14 at the lower limit position. A wooden bottom plate 23 that constitutes a support base together with the frame member 22 is attached to the lower end of the frame member 22. However, the bottom plate can be omitted if necessary. A thin top cover 24 made of a flexible fiber is covered on the entire upper end of the head in a state where the pin member 14 is fully biased by the coil spring material 21, and the periphery of the top is covered with the side of the base plate 11. Covered and fixed. Further, as shown in FIG. 6, mounting holes 13 having screw grooves are provided through the base plate 11 at a plurality of predetermined locations in the base plate 11, and the reinforcing members 25 are provided in the mounting holes 13. Is attached. The reinforcing member 25 is a bolt having a screw 27 on the tip side of the round bar 26, and is screwed into the mounting hole 13 from the lower surface side of the base plate 11 so that the height can be adjusted, and the head portion 28 contacts the bottom plate 23. It is attached in the state.

上記構成の実施例１においては、寝台１０の表面側に体を寝かせることにより、体が薄い上面カバー２４を介してベース板１１全面に非常な高密度で配置されてコイルばね材２１によって強く付勢された多数のピン部材１４の当接部材１６に当接する。これにより、図７に示すように、寝台１０に接触する体の凹凸部分に応じて非常に多数のコイルばね材２１が適正に弾性変形することにより、多数のピン部材１４の他端側がベース板１１の下面側に突出し、また表面側に戻ろうとするように変形する。その際、コイルばね材２１の端部がゴムコーティングされていることにより、ピン部材１４の当接部材１６及びベース板１１上面とコイルばね材２１との接触による異音の発生が抑えられ、また頭部１５ａとベース板１１との接触による異音の発生が緩衝板材１９により抑えられる。その結果、実施例１においては、体の凹凸状態に応じて寝台１０表面が適正に変形するため、体が適正な状態で寝台１０に受け止められることにより、快適な休息状態が確保される。また、コイルばね材２１が収縮しきった状態でピン部材１４の変形が止められるため、体の過大な変形も確実に止められる。さらに、ピン部材１４が沈みきった箇所では、その部分のピン部材１４の山状の当接部材１６が体に強く当たることにより、指圧効果も得られる。 In the first embodiment having the above-described configuration, the body is placed on the entire surface of the base plate 11 through the thin upper cover 24 and is strongly attached by the coil spring material 21 by laying the body on the surface side of the bed 10. It abuts against the abutting members 16 of the numerous pin members 14 that have been urged. As a result, as shown in FIG. 7, a large number of coil spring materials 21 are appropriately elastically deformed according to the uneven portions of the body in contact with the bed 10, so that the other end side of the numerous pin members 14 is the base plate. 11 is projected to the lower surface side and is deformed so as to return to the front surface side. At that time, since the end portion of the coil spring material 21 is rubber-coated, the generation of noise due to the contact between the contact member 16 of the pin member 14 and the upper surface of the base plate 11 and the coil spring material 21 is suppressed. Generation of abnormal noise due to contact between the head 15 a and the base plate 11 is suppressed by the buffer plate material 19. As a result, in Example 1, since the surface of the bed 10 is appropriately deformed according to the uneven state of the body, a comfortable resting state is ensured by the body being received by the bed 10 in an appropriate state. In addition, since the deformation of the pin member 14 is stopped in a state where the coil spring material 21 is fully contracted, excessive deformation of the body can be reliably stopped. Further, at the place where the pin member 14 is completely depressed, the mountain-shaped abutting member 16 of the pin member 14 at that portion strongly hits the body, so that an acupressure effect is also obtained.

また、本実施例１においては、各列間で挿通孔同士を４５°ずれた位置に交互に配置することにより、寝台１０に当接する体の複雑な凹凸状態に応じてピン部材１４の上下変動がより適正に行われ、上述したような寝台１０による体を受け止める作用効果がより適正に発揮される。さらに、実施例１においては、面積の広いベース板１１が、周縁側の枠部材２２に加えて内側の複数個所にて補強部材２５によって補強されるため、重い重量の体を支え続けても変形することなく長期の使用が可能になる。また、実施例１においては、ピン部材１４を樹脂製としたことにより、他の材料に比べて安価にできると共に、量産化も容易であるため、寝台１０の価格も安価にできる。また、多数のピン部材１４を軽量化できるため、寝台１０全体も大幅に軽量化できる。 In the first embodiment, the insertion holes are alternately arranged at positions shifted by 45 ° between the rows, so that the vertical movement of the pin member 14 is changed according to the complicated uneven state of the body in contact with the bed 10. Is performed more appropriately, and the effect of receiving the body by the bed 10 as described above is more appropriately exhibited. Further, in the first embodiment, since the base plate 11 having a large area is reinforced by the reinforcing members 25 at a plurality of inner portions in addition to the frame member 22 on the peripheral side, the base plate 11 is deformed even if a heavy weight body is continuously supported. Long-term use is possible without doing so. Further, in the first embodiment, since the pin member 14 is made of resin, it can be made cheaper than other materials and mass production is easy, so that the price of the bed 10 can be made cheap. Moreover, since many pin members 14 can be reduced in weight, the bed 10 whole can also be reduced in weight significantly.

つぎに、上記実施例２について図８により説明する。
実施例２においては、上記実施例１のベース板１１の裏面側の枠部材内の空間全体を、ゴム弾性体製の弾性支持材２９で充填したことにあり、その他の構成については実施例１と同様である。これにより、実施例２においては、ピン部材１４が表面側でコイルばね材２１によって支持されると共に、裏面側で弾性支持材２９によっても受け止められるため、ピン部材１４の上下変動が一層滑らかに行われ、寝台１０への体に対する接触状態がさらに滑らかにされる。なお、弾性支持材２９については、ゴム弾性体に限らずエラストマー、ウレタン等他の弾性材料でもよく、さらには内部に空気や液体を封入した平坦な袋状のものであってもよい。 Next, the second embodiment will be described with reference to FIG.
In the second embodiment, the entire space in the frame member on the back side of the base plate 11 of the first embodiment is filled with the elastic support member 29 made of a rubber elastic body. It is the same. Thereby, in Example 2, since the pin member 14 is supported by the coil spring material 21 on the front surface side and also received by the elastic support material 29 on the back surface side, the vertical movement of the pin member 14 is performed more smoothly. The contact state with respect to the body to the bed 10 is further smoothed. The elastic support member 29 is not limited to a rubber elastic body, and may be another elastic material such as an elastomer or urethane, or may be a flat bag having air or liquid sealed therein.

つぎに、上記実施例３について図９、図１０により説明する。
実施例３の寝台３０は、上記実施例１のようにピン部材１４をベース板１１の表面側でコイルばね材２１により支持する代わりに、ピン部材１４と同様の構成のピン部材３４をベース板３１の裏面側からコイルばね材３９により支持するようにしたものである。金属製のベース板３１の挿通孔３２にはピン部材３４が挿通孔３２との間にわずかの隙間を保って摺動自在に挿通されている。コイルばね材３９は上端がベース板３１下面の挿通孔３２周囲に溶接等により固定されており、下端がピン部材３４のボルト３５の頭部３５ａに溶接等により固定されている。コイルばね材３９は、収縮した状態でピン部材３４を強い弾性力により上方に向けて付勢している。ベース板３１上面の挿通孔３２周囲には所定長さの円筒形のストッパ４１が固定されている。ストッパ４１の高さは、コイルばね材３９がピン部材３４から力を受けて一杯に伸びきった状態でピン部材３４の当接部材３６が当接し、コイルばね材３９のそれ以上の伸びを抑えている。寝台３０のその他の構成については、実施例１の寝台１０と同様である。 Next, the third embodiment will be described with reference to FIGS.
In the bed 30 of the third embodiment, instead of supporting the pin member 14 by the coil spring material 21 on the surface side of the base plate 11 as in the first embodiment, the pin member 34 having the same configuration as the pin member 14 is used as the base plate. 31 is supported by a coil spring material 39 from the back side. A pin member 34 is slidably inserted into the insertion hole 32 of the metal base plate 31 with a slight gap between the pin member 34 and the insertion hole 32. The upper end of the coil spring material 39 is fixed around the insertion hole 32 on the lower surface of the base plate 31 by welding or the like, and the lower end is fixed to the head portion 35a of the bolt 35 of the pin member 34 by welding or the like. The coil spring material 39 urges the pin member 34 upward with a strong elastic force in a contracted state. A cylindrical stopper 41 having a predetermined length is fixed around the insertion hole 32 on the upper surface of the base plate 31. The height of the stopper 41 is such that the abutting member 36 of the pin member 34 abuts in a state where the coil spring material 39 is fully extended by receiving the force from the pin member 34, and further extension of the coil spring material 39 is suppressed. ing. Other configurations of the bed 30 are the same as those of the bed 10 of the first embodiment.

上記構成の実施例３においては、寝台３０が使用されていない状態では、図９の奇数列に示すように、コイルばね材３９が収縮しきった状態でピン部材３４を上方に向けて付勢しているが、寝台３０に体が横たえられると、ピン部材３４に押されてコイルばね材３９が伸びるようになる。図１０の偶数列に示すように、コイルばね材３９が最大限に伸びきったときに、ピン部材３４の当接部材３６がストッパ４１に当接し、コイルばね材３９のそれ以上の伸びが抑えられる。このようなコイルばね材３９の伸縮によるピン部材３４の上下動により、体が寝台３０に適正に受け止められることにより、実施例３においても実施例１と同様の効果が得られる。実施例３においては、ストッパ４１を設ける代わりに、頭部３６を直接ベース板３１に当接させるようにしてもよい。また、実施例３においても、上記実施例２に示した弾性支持材２９を適用することができる。 In the third embodiment having the above configuration, when the bed 30 is not used, the pin member 34 is urged upward with the coil spring material 39 fully contracted, as shown in the odd-numbered rows of FIG. However, when the body lies on the bed 30, the coil spring material 39 is extended by being pushed by the pin member 34. As shown in the even rows of FIG. 10, when the coil spring material 39 is fully extended, the contact member 36 of the pin member 34 contacts the stopper 41, and further extension of the coil spring material 39 is suppressed. It is done. Due to the vertical movement of the pin member 34 caused by such expansion and contraction of the coil spring material 39, the body is properly received by the bed 30. Thus, the same effect as in the first embodiment can be obtained in the third embodiment. In the third embodiment, instead of providing the stopper 41, the head 36 may be brought into direct contact with the base plate 31. In the third embodiment, the elastic support material 29 shown in the second embodiment can be applied.

つぎに、上記ピン部材１４の変形例について図１１により説明する。ピン部材４４は、樹脂製の棒状部４５とその先端に取り付けられる当接端部である円盤状の当接部材４６とを設けている。棒状部４５は、基部の一端が半球形状の頭部４５ａになっており、他端側に球状のボール部４５ｂが突出して設けられている。当接部材４６は、円盤状の一表面側が山状に膨らんだ円盤部４７と、その軸方向内側に同軸状に取り付けられた短い円筒形の軸部４８とを一体で設けている。軸部４８は、他表面側から凹んで円形に開口している球状の凹部４９を設けており、開口を中心として径方向にわずかに弾性変形可能になっている。ピン部材４４は、棒状部４５をベース板１１の下側から挿通孔１２に差し込んで、先端のボール部４５ｂを当接部材４６の凹部４９に圧入することによりボール部４５ｂが凹部４９にワンタッチで係止されて当接部材４６に固定される。このように、ピン部材４４では、棒状部４５と当接部材４６の連結がワンタッチで容易に行われる。 Next, a modification of the pin member 14 will be described with reference to FIG. The pin member 44 is provided with a resin rod-like portion 45 and a disk-like contact member 46 which is a contact end portion attached to the tip of the pin member 44. One end of the base of the rod-like portion 45 is a hemispherical head 45a, and a spherical ball portion 45b is provided protruding from the other end. The abutting member 46 is integrally provided with a disk portion 47 having a disk-like one surface side swelled in a mountain shape and a short cylindrical shaft portion 48 that is coaxially attached to the inner side in the axial direction. The shaft portion 48 is provided with a spherical concave portion 49 that is recessed from the other surface side and opens in a circular shape, and can be slightly elastically deformed in the radial direction around the opening. The pin member 44 inserts the rod-like portion 45 into the insertion hole 12 from the lower side of the base plate 11, and presses the ball portion 45 b at the tip into the concave portion 49 of the contact member 46, so that the ball portion 45 b can be touched into the concave portion 49 with one touch. It is locked and fixed to the contact member 46. Thus, in the pin member 44, the rod-shaped portion 45 and the contact member 46 are easily connected with one touch.

つぎに、上記実施例４について図１２により説明する。
