しかしながら、特許文献２の製造方法では、張地としてのネットを引っ張って張設した状態で前記ネットをクランプするための部分の内側に枠部材を成形するようにしているので、ネットをクランプするための部分が必要であり、そしてこのクランプするための部分は枠部材の成形後に切断／裁断することが必要とされる。したがって、ネットの無駄が必ず発生するので原料効率が高いとは言えないという問題があり、また、ネットを切断するという余計な作業工程が必要とされるので生産効率が高いとは言えないという問題がある。 However, in the manufacturing method of Patent Document 2, since the frame member is formed inside the portion for clamping the net in a state where the net as the upholstery is pulled and stretched, the net is clamped. Part is required, and this part for clamping needs to be cut / cut after forming the frame member. Therefore, there is a problem that the raw material efficiency cannot be said to be high because the net is always wasted, and there is a problem that the production efficiency cannot be said to be high because an extra work process of cutting the net is required. There is.

そこで、本発明は、張地としての膜部材の無駄が発生しないと共に枠部材成形後に当該枠部材の外側の膜部材を切断する作業工程を必要としない製造工程によって膜部材と枠部材とが一体成形される支持構造物やそのような支持構造物を有する椅子を提供すること、並びに、張地としての膜部材の無駄を発生させることがないと共に枠部材成形後に当該枠部材の外側の膜部材を切断する作業工程が必要とされることなく膜部材と枠部材とを一体成形することができる支持構造物の製造方法を提供することを目的とする。 Therefore, in the present invention, the membrane member and the frame member are integrated by a manufacturing process that does not cause waste of the membrane member as the upholstery and does not require a work step of cutting the outer membrane member of the frame member after molding the frame member. To provide a support structure to be molded and a chair having such a support structure, and to prevent waste of the membrane member as an upholstery, and to prevent the waste of the membrane member as a stretch fabric, and to form the outer membrane member of the frame member after the frame member is molded. It is an object of the present invention to provide a method for manufacturing a support structure capable of integrally forming a film member and a frame member without the need for a work step of cutting the film member.

かかる目的を達成するため、本発明の支持構造物は、膜状部材と当該膜状部材の周縁のうちの少なくとも一部を保持する支持部材とを有し、膜状部材の周縁のうち支持部材と一体的に成形される部分の縁端が支持部材の内部に位置していると共に、成形型の成形溝に設けられた係止ピンに膜状部材の縁が係止されるための係止孔が膜状部材の縁に形成され、膜状部材と支持部材とが一回の成形で一体成形される際に支持部材を成形するための成形型の成形溝の内部に膜状部材の周縁のうち支持部材と一体的に成形される部分の縁を止(とど)めるための膜押圧部材が存在していた穴隙が支持部材に形成されているようにしている。 In order to achieve such an object, the support structure of the present invention has a film-like member and a support member that holds at least a part of the peripheral edge of the film-like member, and the support member among the peripheral edges of the film-like member. The edge of the portion to be integrally molded with is located inside the support member, and the edge of the film-like member is locked to the locking pin provided in the molding groove of the molding die. A hole is formed on the edge of the film-like member, and when the film-like member and the support member are integrally molded by one-time molding, the peripheral edge of the film-like member is inside a molding groove of a molding die for forming the support member. Of these, the support member is formed with a hole in which the film pressing member for stopping (retaining) the edge of the portion integrally molded with the support member was present.

したがって、この支持構造物によると、膜状部材の周縁のうち支持部材と一体的に成形される部分の縁（「膜状部材の一体成形部分の縁」と呼ぶ）が膜押圧部材によって成形溝の内部に止(とど)められるので、膜状部材の一体成形部分の縁の端が枠体である支持部材の内部に存在して（別言すると、位置して）いて、膜状部材の一体成形部分の縁の端が支持部材の外側に出ていることがない。即ち、膜状部材を成形型へと設置する際の位置決めが容易に且つ確実に行われ、また、膜状部材の一体成形部分の縁が適正な位置に仮止めされた状態で当該膜状部材の一体成形部分の縁が膜押圧部材によって止(とど)められる。 Therefore, according to this support structure, the edge of the portion of the peripheral edge of the film-like member that is integrally molded with the support member (referred to as "the edge of the integrally molded portion of the film-like member") is formed by the film pressing member. Since it is stopped inside the film-like member, the end of the edge of the integrally molded part of the film-like member exists inside the support member which is a frame body (in other words, it is located), and the film-like member is located. The edge of the edge of the integrally molded portion of the above does not protrude to the outside of the support member. That is, the film-like member is easily and surely positioned when it is installed in the molding die, and the film-like member is temporarily fixed at an appropriate position at the edge of the integrally molded portion of the film-like member.

第一の型１０の成形溝１２と第二の型２０の成形溝２２とは、第一の型１０と第二の型２０とが組み合わされた状態で相互に対向する位置に形成され、これら二つの成形溝１２，２２によって支持部材３を形成するために当該支持部材３の材料が流し込まれるキャビティ１９が構成される。 The forming groove 12 of the first mold 10 and the forming groove 22 of the second mold 20 are formed at positions facing each other in a state where the first mold 10 and the second mold 20 are combined. The two forming grooves 12 and 22 form a cavity 19 into which the material of the support member 3 is poured in order to form the support member 3.

押さえ具３０は、本体部３１と、当該本体部３１から起立する透き歯状に（別言すると、空隙歯列として）形成される複数の膜押圧部３２とを有する。なお、押さえ具３０は、例えば、第一の型１０や第二の型２０と同様の材料／材質によって形成され得るものであり、また、十分な耐熱性と強度とを発揮し得るものであれば第一の型１０や第二の型２０とは異なる材料／材質によっても形成され得る。 The presser 30 has a main body portion 31 and a plurality of film pressing portions 32 formed in a transparent tooth shape (in other words, as a gap dentition) standing up from the main body portion 31. The presser foot 30 may be formed of, for example, the same material / material as the first mold 10 and the second mold 20, and may exhibit sufficient heat resistance and strength. For example, it can be formed by a material / material different from that of the first mold 10 and the second mold 20.

押さえ具３０は、複数の膜押圧部３２のそれぞれが第一の型１０の成形溝１２に形成されている複数の貫通孔１４の各々に差し込まれて成形溝１２へと進入した状態で、第一の型１０と組み合わされて用いられる。 The presser foot 30 is in a state where each of the plurality of film pressing portions 32 is inserted into each of the plurality of through holes 14 formed in the molding groove 12 of the first mold 10 and enters the molding groove 12. Used in combination with one type 10.

第一の型１０の成形溝１２内の複数の貫通孔１４と押さえ具３０の複数の膜押圧部３２とは、各膜押圧部３２が貫通孔１４の各々へと差し込まれるようにするため、第一の型１０と押さえ具３０とが組み合わされて用いられる状態においてそれぞれの位置が一致するように形成されたり設けられたりする。 The plurality of through holes 14 in the forming groove 12 of the first mold 10 and the plurality of film pressing portions 32 of the presser 30 are for inserting each film pressing portion 32 into each of the through holes 14. In a state where the first mold 10 and the presser foot 30 are used in combination, they are formed or provided so that their respective positions match.

したがって、複数の膜押圧部３２は、全体として、第一の型１０と押さえ具３０とが組み合わされて用いられる状態において第一の型１０の膜状部材設置台部１１を断続的に取り囲むように形成される。 Therefore, the plurality of film pressing portions 32 intermittently surround the film-like member installation base portion 11 of the first mold 10 in a state where the first mold 10 and the presser 30 are used in combination as a whole. Is formed in.

各膜押圧部３２は、本体部３１から起立する部分である胴部３２ａと、当該胴部３２ａの先端部が鉤形に屈曲して形成される膜押圧爪３２ｂとを有する。 Each film pressing portion 32 has a body portion 32a that is a portion that stands up from the main body portion 31, and a film pressing claw 32b that is formed by bending the tip portion of the body portion 32a into a hook shape.

各膜押圧爪３２ｂは、胴部３２ａから、第一の型１０の膜状部材押圧台部１５の上方へとせり出すように突出する（つまり、膜状部材設置台部１１の側へと屈曲して膜状部材押圧台部１５の側へと突き出る）ものとして形成される。 Each film pressing claw 32b protrudes from the body portion 32a so as to protrude upward from the film-like member pressing base portion 15 of the first mold 10 (that is, bends toward the film-like member installation base portion 11). (Protrudes toward the film-like member pressing base 15).

ここで、膜状部材２の平面視における輪郭形状と、複数の膜押圧部３２の胴部３２ａによって取り囲まれる領域の輪郭形状とが、一致する若しくは概ね一致するように調整される。さらに、膜状部材２の平面視における外形線（別言すると、周縁端）が、第一の型１０の成形溝１２内に位置する（言い換えると、存在する）ように調整される。 Here, the contour shape of the film-like member 2 in a plan view and the contour shape of the region surrounded by the body portions 32a of the plurality of film pressing portions 32 are adjusted to match or substantially match. Further, the outer line (in other words, the peripheral edge) of the film-like member 2 in a plan view is adjusted so as to be located (in other words, present) in the forming groove 12 of the first mold 10.

押さえ具３０は、図示していない駆動機構により、第一の型１０の貫通孔１４からの膜押圧部３２の突出の程度が変化するように、延いては第一の型１０の膜状部材押圧台部１５の対向面に対する膜押圧部３２の膜押圧爪３２ｂの離隔の程度が変化するように、第一の型１０に対して相対的に移動可能であるように構成される。 The presser foot 30 is a film-like member of the first mold 10 so that the degree of protrusion of the film pressing portion 32 from the through hole 14 of the first mold 10 is changed by a drive mechanism (not shown). It is configured to be relatively movable with respect to the first mold 10 so that the degree of separation of the film pressing claw 32b of the film pressing portion 32 with respect to the facing surface of the pressing base portion 15 changes.

臀部支持構造物１の製造方法の具体的な内容を以下に説明する。 The specific contents of the manufacturing method of the buttock support structure 1 will be described below.

ここで、本発明の説明では、第一の型１０に対する押さえ具３０の移動の向きについて、図１や図６乃至図１０における上向きのことを「膜押圧部３２が突き出る向き」と言うと共に下向きのことを「膜押圧部３２が引き込む向き」と言う。 Here, in the description of the present invention, regarding the direction of movement of the presser foot 30 with respect to the first mold 10, the upward direction in FIGS. 1 and 6 to 10 is referred to as "the direction in which the film pressing portion 32 protrudes" and downward. This is referred to as "the direction in which the film pressing portion 32 is pulled in".

臀部支持構造物１の製造方法の手順としては、まず、膜状部材押圧台部１５の対向面と膜押圧部３２の膜押圧爪３２ｂとが離隔してこれらの間に隙間が生じるように、第一の型１０に対する押さえ具３０の相対位置が膜押圧部３２が突き出る向きに駆動機構（図示していない）によって調節される。 As a procedure for manufacturing the buttock support structure 1, first, the facing surface of the film-like member pressing base 15 and the film pressing claw 32b of the film pressing portion 32 are separated from each other so that a gap is formed between them. The relative position of the presser 30 with respect to the first mold 10 is adjusted by a drive mechanism (not shown) in the direction in which the film pressing portion 32 protrudes.

第一の型１０の膜状部材設置台部１１に膜状部材２が広げられてセット（別言すると、設置）され、当該膜状部材２の周縁に形成されている複数の係止孔２ａのそれぞれへと係止ピン１３を差し込ませるようにして当該膜状部材２の周縁が第一の型１０に係止される（具体的には、複数の係止孔２ａのそれぞれが各係止ピン１３に係止される）。 A plurality of locking holes 2a formed on the peripheral edge of the film-like member 2 in which the film-like member 2 is spread and set (in other words, installed) on the film-like member installation base 11 of the first mold 10. The peripheral edge of the film-like member 2 is locked to the first mold 10 by inserting the locking pin 13 into each of the above (specifically, each of the plurality of locking holes 2a is locked. Locked to pin 13).

このとき、膜状部材押圧台部１５と膜押圧部３２の膜押圧爪３２ｂとの間には上述のように駆動機構による調節によって隙間が生じており、当該隙間へと膜状部材２の周縁が入り込ませられる。 At this time, a gap is generated between the film-like member pressing base portion 15 and the film-pressing claw 32b of the film-like member 32 due to the adjustment by the drive mechanism as described above, and the peripheral edge of the film-like member 2 is formed in the gap. Is made to enter.

第一の型１０の膜状部材設置台部１１に広げられて設置された膜状部材２の周縁が係止ピン１３に係止されたり膜状部材押圧台部１５と膜押圧部３２の膜押圧爪３２ｂとの間の隙間へと入り込ませられたりした状態で、第一の型１０に対する押さえ具３０の相対位置が膜押圧部３２が引き込む向きに駆動機構によって調節され、膜押圧部３２の膜押圧爪３２ｂによって膜状部材２の周縁が膜状部材押圧台部１５へと押さえ付けられて止(とど)められる。 The peripheral edge of the film-like member 2 spread and installed on the film-like member installation base 11 of the first mold 10 is locked to the locking pin 13, or the film of the film-like member pressing base 15 and the film pressing portion 32. The relative position of the presser foot 30 with respect to the first mold 10 is adjusted by the drive mechanism in the direction in which the film pressing portion 32 is retracted in a state where the pressing tool 30 is inserted into the gap between the pressing claw 32b and the film pressing portion 32. The peripheral edge of the film-like member 2 is pressed against the film-like member pressing base 15 by the film-pressing claw 32b and stopped.

これにより、膜状部材２の周縁が、膜押圧爪３２ｂによって膜状部材押圧台部１５の対向面へと押さえ付けられて止(とど)められる（言い換えると、膜状部材押圧台部１５と膜押圧爪３２ｂとの間に挟まれて係止されて固定される）。 As a result, the peripheral edge of the film-like member 2 is pressed against the facing surface of the film-like member pressing base 15 by the film pressing claw 32b and stopped (in other words, the film-like member pressing base 15). It is sandwiched between the film pressing claw 32b and the film pressing claw 32b, and is locked and fixed).

膜状部材設置台部１１に膜状部材２が広げられてセット（設置）され且つ当該膜状部材２の周縁が係止孔２ａを介して係止ピン１３に係止されていると共に膜押圧爪３２ｂによって押さえ付けられ止(とど)められて固定されている状態の第一の型１０へと、図示していない駆動機構により、第二の型２０が合わせられて密着させられる（言い換えると、合体させられる）。 The film-like member 2 is spread out and set (installed) on the film-like member installation base 11, and the peripheral edge of the film-like member 2 is locked to the locking pin 13 via the locking hole 2a and the film is pressed. The second mold 20 is aligned and brought into close contact with the first mold 10 in a state of being pressed and stopped by the claw 32b by a drive mechanism (not shown) (in other words). And can be combined).

このとき、第一の型１０の成形溝１２と第二の型２０の成形溝２２とによって形成／構成されるキャビティ１９内に、係止ピン１３及び膜押圧部３２（特に、膜押圧爪３２ｂ）が存在し、また、膜状部材２の平面視における輪郭全周分の周縁（特に、外形端）が位置する。 At this time, the locking pin 13 and the film pressing portion 32 (particularly, the film pressing claw 32b) are contained in the cavity 19 formed / formed by the forming groove 12 of the first mold 10 and the forming groove 22 of the second mold 20. ) Exists, and the peripheral edge (particularly, the outer edge) of the entire circumference of the contour in the plan view of the film-like member 2 is located.

ここで、本発明では、第一の型１０の成形溝１２と第二の型２０の成形溝２２とによって形成／構成されるキャビティ１９内に膜状部材２の縁や縁端が位置する（言い換えると、存在する）ことを、膜状部材２の縁や縁端が成形溝１２，２２を区画する面、即ちキャビティ１９の内周面と接触している態様も含めて、「膜状部材２の縁／縁端が成形溝１２，２２の内部に位置／存在する」と言い表す。 Here, in the present invention, the edge or edge of the film-like member 2 is located in the cavity 19 formed / formed by the forming groove 12 of the first mold 10 and the forming groove 22 of the second mold 20 ( In other words, it exists), including the aspect in which the edge or edge of the film-like member 2 is in contact with the surface that partitions the forming grooves 12, 22, that is, the inner peripheral surface of the cavity 19. The edge / edge of 2 is located / present inside the forming grooves 12 and 22 ".

なお、キャビティ１９内の各係止ピン１３及び各膜押圧部３２と第二の型２０（具体的には、成形溝２２を区画する面、即ち、キャビティ１９の内周面）との間には空隙が生じるように各係止ピン１３，各膜押圧部３２，及び成形溝２２に纏わる寸法が調整される。 It should be noted that between each locking pin 13 and each film pressing portion 32 in the cavity 19 and the second mold 20 (specifically, the surface for partitioning the forming groove 22, that is, the inner peripheral surface of the cavity 19). The dimensions of each locking pin 13, each film pressing portion 32, and the forming groove 22 are adjusted so as to generate a gap.

第一の型１０と第二の型２０とが組み合わせられた状態で、支持部材３の材料（例えば、溶融状態の樹脂）がキャビティ１９へと流し込まれる。なお、支持部材３の材料を流し込むための流路が、成形溝１２，２２と連通する貫通孔として、第一の型１０と第二の型２０とのうちの少なくとも一方に設けられる（図示していない）。 In a state where the first mold 10 and the second mold 20 are combined, the material of the support member 3 (for example, a molten resin) is poured into the cavity 19. A flow path for pouring the material of the support member 3 is provided in at least one of the first mold 10 and the second mold 20 as a through hole communicating with the forming grooves 12 and 22 (shown in the figure). Not).

支持部材３の材料がキャビティ１９へと流し込まれる際に、膜状部材２の周縁は係止孔２ａを介して係止ピン１３に係止された上で膜状部材押圧台部１５と膜押圧爪３２ｂとの間に挟まれて固定されているので、流し込まれる材料によって膜状部材２が移動してしまったり膜状部材２の周縁がめくれてしまったりすることがなく、膜状部材２の平面視における輪郭全周分の周縁（特に、外形端）がキャビティ１９内の所定位置に位置したままの状態が確実に維持される。 When the material of the support member 3 is poured into the cavity 19, the peripheral edge of the film-like member 2 is locked to the locking pin 13 via the locking hole 2a, and then the film-like member pressing base 15 and the film pressing. Since it is sandwiched and fixed between the claws 32b and the film-like member 2, the film-like member 2 does not move or the peripheral edge of the film-like member 2 does not turn over due to the poured material, and the film-like member 2 The state in which the peripheral edge (particularly, the outer edge) of the entire circumference of the contour in the plan view remains positioned at a predetermined position in the cavity 19 is surely maintained.

そして、キャビティ１９へと流し込まれた材料が固化した後に、第二の型２０が第一の型１０から引き離され、膜状部材２の周縁に沿って枠状の支持部材３が一体的に形成された状態の臀部支持構造物１が第一の型１０から取り外される。 Then, after the material poured into the cavity 19 is solidified, the second mold 20 is separated from the first mold 10, and the frame-shaped support member 3 is integrally formed along the peripheral edge of the film-like member 2. The buttock support structure 1 in the removed state is removed from the first mold 10.

臀部支持構造物１が第一の型１０から取り外される際には、膜状部材押圧台部１５の対向面と膜押圧部３２の膜押圧爪３２ｂとが離隔してこれらの間に隙間が生じるように、第一の型１０に対して押さえ具３０が膜押圧部３２が突き出る向きに移動させられる。 When the buttock support structure 1 is removed from the first mold 10, the facing surface of the film-like member pressing base 15 and the film pressing claw 32b of the film pressing portion 32 are separated from each other, and a gap is formed between them. As described above, the pressing tool 30 is moved with respect to the first mold 10 in the direction in which the film pressing portion 32 protrudes.

ここで、第一の型１０から取り外された臀部支持構造物１の支持部材３の下面には、成形時に膜押圧部３２の膜押圧爪３２ｂや膜状部材押圧台部１５が存在すると共に成形後に臀部支持構造物１が第一の型１０から取り外される際に膜押圧爪３２ｂが通過するための空間／空洞である膜押圧部材穴隙３ａが、成形時に第一の型１０のうち成形溝１２を区画する部位の一部が存在していた空間／空洞である成形型穴隙３ｂと一体のものとして（言い換えると、連通するものとして）形成されている（図１０；尚、同図(Ａ)においては、成形時における膜押圧部３２の胴部３２ａ及び膜押圧爪３２ｂを仮想物として表していると共に、第一の型１０のうちの成形溝１２を区画する部位の一部を当該一部自体の図示は省略しつつ当該一部が存在する空間を括弧を付した符号１０として表している）。 Here, on the lower surface of the support member 3 of the buttock support structure 1 removed from the first mold 10, the film pressing claw 32b of the film pressing portion 32 and the film-like member pressing base portion 15 are present at the time of molding, and molding is performed. The membrane pressing member hole 3a, which is a space / cavity through which the membrane pressing claw 32b passes when the buttock support structure 1 is later removed from the first mold 10, is formed in the forming groove of the first mold 10 at the time of molding. It is formed as an integral part (in other words, as a communication) with the molded hole gap 3b, which is a space / cavity in which a part of the portion partitioning the 12 is present (FIG. 10; In A), the body portion 32a and the film pressing claw 32b of the film pressing portion 32 at the time of molding are represented as virtual objects, and a part of the portion of the first mold 10 for partitioning the forming groove 12 is concerned. Although the illustration of the part itself is omitted, the space in which the part exists is represented by reference numeral 10 with parentheses).

なお、膜押圧部材穴隙３ａは、支持部材３を成形する際に膜状部材２の周縁を第一の型１０の膜状部材押圧台部１５へと押し付ける膜押圧部３２の膜押圧爪３２ｂや前記膜状部材押圧台部１５が存在していた空隙であるとも言える。 The membrane pressing member hole 3a is a membrane pressing claw 32b of the membrane pressing portion 32 that presses the peripheral edge of the membrane member 2 against the membrane member pressing base portion 15 of the first mold 10 when molding the support member 3. It can also be said that this is a gap in which the film-like member pressing base portion 15 was present.

そして、支持部材３の、膜押圧部材穴隙３ａ内に、膜状部材２の周縁端が存在する（別言すると、位置する）。 Then, the peripheral edge of the film-like member 2 exists in the film pressing member hole 3a of the support member 3 (in other words, it is located).

ここで、本発明では、膜押圧部材穴隙３ａは支持部材３に形成されて当該支持部材３の一部を構成する部位であると捉え、膜状部材２の縁や縁端が膜押圧部材穴隙３ａに存在／位置することを「膜状部材２の縁／縁端が支持部材３の内部に存在／位置する」と言い表す。 Here, in the present invention, the film pressing member hole 3a is regarded as a portion formed in the support member 3 and constituting a part of the support member 3, and the edge or edge of the film-like member 2 is the film pressing member. Existence / position in the hole 3a is referred to as "the edge / edge of the film-like member 2 exists / is located inside the support member 3".

また、係止ピン１３が設けられている部位では、成形時に係止ピン１３が存在する空間／空洞である係止部材穴隙が、成形時に第一の型１０のうち成形溝１２を区画する部位の一部が存在していた空間／空洞である成形型穴隙３ｂと一体のもの（言い換えると、連通するもの）として形成されている。 Further, in the portion where the locking pin 13 is provided, the locking member hole gap, which is a space / cavity in which the locking pin 13 exists at the time of molding, partitions the molding groove 12 of the first mold 10 at the time of molding. It is formed as an integral part (in other words, a communication type) with the molded hole gap 3b, which is a space / cavity in which a part of the portion was present.

以上により、膜状部材２の周縁に沿って枠状の支持部材３が一体的に形成されている（言い換えると、膜状部材２と支持部材３とが一体化された）一体成形品として臀部支持構造物１が製造される。 As described above, the frame-shaped support member 3 is integrally formed along the peripheral edge of the film-like member 2 (in other words, the film-like member 2 and the support member 3 are integrated) as an integrally molded product. The support structure 1 is manufactured.

なお、膜状部材２への、着座者の身体を支える支持面を構成するものとして必要とされる弾性力を発揮させる張力の付与は、第一の型１０へと膜状部材２を設置する際に予張力を与えておくようにしたり、一体成形後にヒートセットによって与えるようにしたり、或いは、第一の型１０への設置の際の予張力の付与と一体成形後のヒートセットによる付与とを併用するようにしたりする。なお、ヒートセットとは、加熱した熱源を膜状部材２に当接或いは接近させることで膜状部材２を熱収縮させることによって予張力を付与することをいう。 To apply tension to the film-like member 2 to exert the elastic force required for constituting the support surface that supports the seated person's body, the film-like member 2 is installed in the first mold 10. Pre-tension may be applied at the time, pre-tension may be applied by heat set after integral molding, or pre-tension may be applied at the time of installation in the first mold 10 and applied by heat set after integral molding. To be used together. The heat set means that a pretension is applied by heat-shrinking the film-like member 2 by bringing the heated heat source into contact with or close to the film-like member 2.

なお、膜状部材２と支持部材３とを一体化して一体成形する方法は、上述の射出成形法に限られるものではなく、圧縮成形法や注型法などの他の方法であっても良い。 The method of integrally molding the film-shaped member 2 and the support member 3 is not limited to the above-mentioned injection molding method, but may be another method such as a compression molding method or a casting method. ..

以上のように構成された支持構造物及び椅子並びに支持構造物の製造方法によれば、膜状部材２の周縁を膜押圧爪３２ｂによって第一の型１０の膜状部材押圧台部１５へと押し付けて止(とど)めるようにしているので、枠体である支持部材３の内部に膜状部材２の周縁端を確実に存在させて（別言すると、位置させて）膜状部材２の周縁端が支持部材３の外側に出てしまうことを防止することができる。このため、不良の無い臀部支持構造物１を確実に製造することが可能になる。 According to the support structure, the chair, and the method for manufacturing the support structure configured as described above, the peripheral edge of the film-like member 2 is moved to the film-like member pressing base 15 of the first mold 10 by the film pressing claw 32b. Since the film-like member is pressed and stopped, the peripheral end of the film-like member 2 is surely present (in other words, positioned) inside the support member 3 which is a frame body. It is possible to prevent the peripheral edge of 2 from protruding to the outside of the support member 3. Therefore, it becomes possible to reliably manufacture the buttock support structure 1 having no defects.

以上のように構成された支持構造物及び椅子並びに支持構造物の製造方法によれば、また、枠体である支持部材３の内部に膜状部材２の周縁端が確実に存在／位置するので、支持部材３の外側に出てしまう膜状部材２を覆うための二次成形を行うことなく一回の成形で臀部支持構造物１を完成させるようにすることもでき、且つ、支持部材３の成形後に当該支持部材３の外側の膜状部材２の周縁端部を切断する作業工程が必要とされることなく膜状部材２と枠状の支持部材３とを一体成形して臀部支持構造物１を完成させることができる。このため、余計な手間・工程を経ることなく効率的に良好な臀部支持構造物１を製造することが可能になる。 According to the method for manufacturing the support structure, the chair, and the support structure configured as described above, and because the peripheral edge of the film-like member 2 is surely present / positioned inside the support member 3 which is a frame body. It is also possible to complete the buttock support structure 1 by one molding without performing secondary molding for covering the film-like member 2 that protrudes to the outside of the support member 3, and the support member 3 can be completed. The buttock support structure is formed by integrally molding the film-shaped member 2 and the frame-shaped support member 3 without the need for a work step of cutting the peripheral end portion of the film-shaped member 2 on the outer side of the support member 3. The thing 1 can be completed. Therefore, it is possible to efficiently manufacture a good buttock support structure 1 without going through extra labor and steps.

The present invention is applicable as long as the film-like member and the support member are integrally molded in at least a part of the above. Further, in consideration of the above, the present invention relates to a portion of the peripheral edge of the film-like member that is held by the support member, and further to a portion in which the film-like member and the support member are integrally formed. Is applicable.

また、上述の実施形態では貫通孔１４及び膜状部材押圧台部１５が成形溝１２の対向面視における形状に各々の長手方向が沿うように形成されると共に全体として膜状部材設置台部１１を断続的に取り囲むように形成されるようにしているが、貫通孔１４（加えて、膜押圧部３２の胴部３２ａ）や膜状部材押圧台部１５の形態は上述の実施形態における形態には限定されない。 Further, in the above-described embodiment, the through hole 14 and the film-like member pressing base portion 15 are formed so that their longitudinal directions follow the shape of the forming groove 12 in the facing plane view, and the film-like member installation base portion 11 as a whole. Is formed so as to intermittently surround the membrane, but the form of the through hole 14 (in addition, the body portion 32a of the film pressing portion 32) and the film-like member pressing base portion 15 are the same as those in the above-described embodiment. Is not limited.

また、上述の実施形態では第一の型１０の成形溝１２内には何も設けられていないが、膜状部材２の支(つか)え／突っ支いとして機能して成形溝１２内に於ける膜状部材２の位置を安定させるための構造／仕掛けとして膜状部材支持部１６が成形溝１２内に設けられるようにしても良い（図１１）。 Further, in the above-described embodiment, nothing is provided in the forming groove 12 of the first mold 10, but the film-like member 2 functions as a support / support in the forming groove 12. As a structure / mechanism for stabilizing the position of the film-like member 2 in the film-like member 2, the film-like member support portion 16 may be provided in the forming groove 12 (FIG. 11).

膜状部材支持部１６は、具体的には、対向面視において膜状部材押圧台部１５と膜状部材設置台部１１との間に、これら膜状部材押圧台部１５及び膜状部材設置台部１１とは離間して（言い換えると、膜状部材押圧台部１５との間及び膜状部材設置台部１１との間のそれぞれに、支持部材３の材料が流れ込むキャビティ１９の一部としての溝が設けられて）細長状の突部として複数個形成される。 Specifically, the membrane-like member support portion 16 is provided with the membrane-like member pressing base portion 15 and the membrane-like member installation portion between the membrane-like member pressing base portion 15 and the membrane-like member installation base portion 11 in a facing view. As a part of the cavity 19 into which the material of the support member 3 flows, apart from the base portion 11 (in other words, between the membrane-like member pressing base portion 15 and the membrane-like member installation base portion 11 respectively. A plurality of elongated protrusions are formed (provided with a groove).

膜状部材支持部１６について、膜状部材押圧台部１５と膜状部材設置台部１１との間に形成されるとは、近傍（更に言えば、直近）の膜押圧部３２や膜状部材押圧台部１５よりも対向面視において膜状部材設置台部１１寄りの位置（言い換えると、膜状部材２及び支持部材３の平面視において近傍（直近）の膜押圧部３２や膜状部材押圧台部１５よりも内側）に形成されるという意味である。 Regarding the membrane-like member support portion 16, what is formed between the membrane-like member pressing base portion 15 and the membrane-like member installation base portion 11 is the membrane-like member pressing portion 32 or the membrane-like member in the vicinity (more specifically, the nearest). The position closer to the film-like member installation base 11 than the pressing table 15 (in other words, pressing the film-like member 32 or the film-like member in the vicinity (closest) in the plan view of the film-like member 2 and the support member 3). It means that it is formed inside the base 15).

具体的には、膜状部材設置台部１１から見た膜状部材押圧台部１５と膜状部材支持部１６とが視線方向において重なっていても重なっていなくてもどちらでも良く、したがって対向面視において隣り合う膜状部材押圧台部１５同士の間で且つこれら隣り合う膜状部材押圧台部１５同士を結ぶラインよりも膜状部材設置台部１１寄りの位置に膜状部材支持部１６が形成されても良い。 Specifically, the film-like member pressing base 15 and the film-like member support 16 seen from the film-like member installation base 11 may or may not overlap in the line-of-sight direction, and therefore the facing surfaces thereof. The film-like member support portion 16 is located between the adjacent film-like member pressing bases 15 and closer to the film-like member installation base 11 than the line connecting the adjacent film-like member pressing bases 15. It may be formed.

膜状部材支持部１６は、本実施形態では、支持部材３のうちの前辺に相当する部分（即ち、臀部支持構造物１の前端部）のみに対して設けられる。 In the present embodiment, the film-like member support portion 16 is provided only on the portion corresponding to the front side of the support member 3 (that is, the front end portion of the buttock support structure 1).

しかしながら、膜状部材支持部１６が設けられる箇所／範囲は、支持部材３のうちの前辺に相当する部分に限られるものではなく、左右の側辺に相当する部分に設けられるようにしたり、後辺に相当する部分に設けられるようにしたりしても良い。 However, the location / range in which the film-shaped member support portion 16 is provided is not limited to the portion corresponding to the front side of the support member 3, but may be provided in the portion corresponding to the left and right side sides. It may be provided in the portion corresponding to the rear side.

付け加えると、膜状部材支持部１６は、枠状の支持部材３を構成する各辺のうちの一部の辺のみに設けられるようにしても良く、或いは、枠状の支持部材３を構成する各辺の全ての辺に（言い換えると、枠状の支持部材３の全周に亙って）設けられるようにしても良い。 In addition, the film-shaped member support portion 16 may be provided only on a part of each side constituting the frame-shaped support member 3, or constitutes the frame-shaped support member 3. It may be provided on all sides of each side (in other words, over the entire circumference of the frame-shaped support member 3).

膜状部材支持部１６は、また、枠状の支持部材３を構成する辺の各々において、各辺のうちの一部分のみに設けられるようにしても良く、或いは、各辺の全体（別言すると、全長）に亙って設けられるようにしても良い。 The film-shaped member support portion 16 may also be provided on only a part of each side on each of the sides constituting the frame-shaped support member 3, or the entire side (in other words, in other words). , Overall length) may be provided.

膜状部材支持部１６は、さらに、枠状の支持部材３を構成する辺の各々において、連続的に一つ（別言すると、一体）設けられるようにしても良く、或いは、断続的に複数個設けられるようにしても良い。 Further, one film-shaped member support portion 16 may be continuously provided (in other words, integrally) on each side constituting the frame-shaped support member 3, or a plurality of film-shaped member support portions 16 may be provided intermittently. It may be provided individually.

膜状部材支持部１６の形状は、成形溝１２内に於いて膜状部材２を支(ささ)えて当該膜状部材２の成形溝１２内に於ける位置を安定させ得るものであれば特定の形態に限定されるものではなく、図に示す例のように成形溝１２の対向面視における形状に各々の長手方向が沿う細長状の台座として設けられるようにしても良く、或いは、例えば棒状の柱体として設けられるようにしても良い。 The shape of the film-like member support portion 16 is specified as long as it can support the film-like member 2 in the forming groove 12 and stabilize the position of the film-like member 2 in the forming groove 12. The form is not limited to the above, and may be provided as an elongated pedestal along each longitudinal direction along the shape of the forming groove 12 in the facing plane as in the example shown in the figure, or, for example, a rod shape. It may be provided as a pillar of.

臀部支持構造物１が製造される際（特に、支持部材３の材料がキャビティ１９へと流し込まれる際）に、成形溝１２内に設けられている膜状部材支持部１６が、成形溝１２内に於ける膜状部材２の位置を安定させる仕組みとして機能する。 When the buttock support structure 1 is manufactured (particularly when the material of the support member 3 is poured into the cavity 19), the film-like member support portion 16 provided in the molding groove 12 is formed in the molding groove 12. It functions as a mechanism for stabilizing the position of the film-like member 2 in the above.

具体的には、膜状部材支持部１６が無い場合には、膜状部材設置台部１１に膜状部材２が設置されると共に第一の型１０と第二の型２０とが組み合わされた状態で支持部材３の材料がキャビティ１９へと流し込まれると、膜状部材２（特に、縁の端を除く、膜状部材２の平面視において縁の端よりも内側の部分）が膜状部材設置台部１１の方へと寄ってしまい、更には膜状部材２が膜状部材設置台部１１へと張り付いてしまう場合がある（図１２）。 Specifically, when there is no film-like member support portion 16, the film-like member 2 is installed on the film-like member installation base portion 11, and the first mold 10 and the second mold 20 are combined. When the material of the support member 3 is poured into the cavity 19 in this state, the film-like member 2 (particularly, the portion inside the edge of the film-like member 2 in the plan view excluding the edge of the edge) becomes the film-like member. In some cases, the film-like member 2 may move toward the installation base 11 and the film-like member 2 may stick to the film-like member installation table 11 (FIG. 12).

そして、膜状部材２（特に、縁の端を除く、膜状部材２の平面視において縁の端よりも内側の部分）が膜状部材設置台部１１の方へと寄ってしまった場合には、臀部支持構造物１として形成された状態の膜状部材２が所望の形状ではない形状に張設されてしまったり前記膜状部材２に皺や弛みが生じてしまったりなどすることが考えられ、また、臀部支持構造物１として形成された状態の膜状部材２（特に、縁の端を除く、膜状部材２の平面視において縁の端よりも内側の部分）が支持部材３の表面（特に、上面や側面）に露出してしまうことも考えられる。 Then, when the film-like member 2 (particularly, the portion inside the edge of the film-like member 2 in the plan view excluding the edge of the edge) approaches the film-like member installation base portion 11. It is conceivable that the film-like member 2 formed as the buttock support structure 1 may be stretched into a shape other than the desired shape, or the film-like member 2 may be wrinkled or loosened. Further, the film-like member 2 in a state of being formed as the buttock support structure 1 (particularly, the portion inside the edge of the film-like member 2 in the plan view excluding the edge of the edge) is the support member 3. It is also possible that it will be exposed on the surface (particularly the top surface and side surfaces).

一方、成形溝１２内に膜状部材支持部１６が設けられた場合には、支持部材３の材料がキャビティ１９へと流し込まれた際に膜状部材２が膜状部材設置台部１１の方へと寄ろうとしても、膜状部材支持部１６が障害物（別言すると、支(つか)え，突っ支い）になって膜状部材設置台部１１の方へと近寄ることができない（図１３）。このため、膜状部材２の周縁部は成形溝１２内に於いて位置が安定して成形溝１２内に膜状部材２（特に、縁の端を除く、膜状部材２の平面視において縁の端よりも内側の部分）の周縁端が確実に位置するようになる。 On the other hand, when the film-like member support portion 16 is provided in the forming groove 12, the film-like member 2 is directed toward the film-like member installation base portion 11 when the material of the support member 3 is poured into the cavity 19. Even if you try to approach the film-like member, the film-like member support portion 16 becomes an obstacle (in other words, a support or a support) and cannot approach the film-like member installation base portion 11 (in other words). FIG. 13). Therefore, the peripheral portion of the film-like member 2 has a stable position in the forming groove 12, and the film-like member 2 (particularly, the edge in the plan view of the film-like member 2 excluding the edge of the edge) is formed in the forming groove 12. The peripheral edge (the part inside the edge of) is surely positioned.

なお、製造される臀部支持構造物１において、膜状部材支持部１６が設けられている部位には、成形時に膜状部材支持部１６が存在する空間／空洞である支持部穴隙３ｃが、成形時に第一の型１０のうち成形溝１２を区画する部位の一部が存在していた空間／空洞である成形型穴隙３ｂと一体のもの（言い換えると、連通するもの）として形成される（図１４）。 In the manufactured buttock support structure 1, a support portion hole 3c, which is a space / cavity in which the film-like member support portion 16 is present at the time of molding, is provided at a portion where the film-like member support portion 16 is provided. It is formed as an integral part (in other words, one that communicates) with the molding mold hole 3b, which is a space / cavity in which a part of the portion of the first mold 10 that partitions the molding groove 12 was present at the time of molding. (Fig. 14).

また、成形時に膜状部材支持部１６が存在する空間／空洞である支持部穴隙３ｃを挟んで対向する一対のリブ３ｄ，３ｅが形成される。具体的には、成形型穴隙３ｂと支持部穴隙３ｃとの間に下向きに突出する第一のリブ３ｄが形成され、支持部穴隙３ｃと膜状部材設置台部１１との間に下向きに突出する第二のリブ３ｅが形成される。これら一対のリブ３ｄ，３ｅは、支持部穴隙３ｃを挟んで形成される二重のリブであるとも言える。なお、これら一対のリブ３ｄ，３ｅは、本発明に特有の製造方法・構成の結果として形成されるものであり、補強のためだけに形成されるものではない。 Further, a pair of ribs 3d and 3e facing each other across the support portion hole gap 3c, which is a space / cavity in which the film-like member support portion 16 exists at the time of molding, are formed. Specifically, a first rib 3d projecting downward is formed between the molding die hole gap 3b and the support portion hole gap 3c, and between the support portion hole gap 3c and the film-like member installation base portion 11. A second rib 3e projecting downward is formed. It can be said that these pair of ribs 3d and 3e are double ribs formed with the support portion hole gap 3c interposed therebetween. It should be noted that these pairs of ribs 3d and 3e are formed as a result of the manufacturing method / configuration peculiar to the present invention, and are not formed only for reinforcement.

また、上述の形態では膜状部材支持部１６が第一の型１０の一部として（別言すると、一体のものとして）形成されるようにしているが、膜状部材支持部１６は第一の型１０とは別体のものとして設けられるようにしても良い。具体的には例えば、上述の実施形態における膜状部材支持部１６の代わりに、当該膜状部材支持部１６の位置・部分にインサート部材１７が設置されるようにしても良い。この場合は、第一の型１０の膜状部材押圧台部１５と膜状部材設置台部１１との間にインサート部材１７が設置された状態で膜状部材設置台部１１に膜状部材２がセットされて成形が行われ（図１５）、臀部支持構造物１が第一の型１０から取り外される際にインサート部材１７も支持部材３と一緒に（言い換えると、支持部材３と一体になって）取り外される。この場合には、また、インサート部材１７を挟んで対向する一対のリブ３ｄ，３ｅが形成される。具体的には、成形時に第一の型１０のうち成形溝１２を区画する部位の一部が存在していた空間／空洞である成形型穴隙３ｂとインサート部材１７との間に下向きに突出する第一のリブ３ｄが形成され、インサート部材１７と膜状部材設置台部１１との間に下向きに突出する第二のリブ３ｅが形成される。これら一対のリブ３ｄ，３ｅは、インサート部材１７を挟んで形成される二重のリブであるとも言える。 Further, in the above-described form, the film-like member support portion 16 is formed as a part of the first mold 10 (in other words, as an integral body), but the film-like member support portion 16 is the first. It may be provided as a separate body from the mold 10. Specifically, for example, the insert member 17 may be installed at the position / portion of the film-like member support portion 16 instead of the film-like member support portion 16 in the above-described embodiment. In this case, the film-like member 2 is placed on the film-like member installation base 11 with the insert member 17 installed between the film-like member pressing base 15 of the first mold 10 and the film-like member installation base 11. Is set and molding is performed (FIG. 15), and when the buttock support structure 1 is removed from the first mold 10, the insert member 17 is also integrated with the support member 3 (in other words, is integrated with the support member 3). It will be removed. In this case, also, a pair of ribs 3d and 3e facing each other with the insert member 17 interposed therebetween are formed. Specifically, it protrudes downward between the mold hole gap 3b, which is a space / cavity in which a part of the portion of the first mold 10 that partitions the molding groove 12 was present, and the insert member 17. The first rib 3d to be formed is formed, and the second rib 3e projecting downward is formed between the insert member 17 and the film-like member installation base portion 11. It can be said that these pair of ribs 3d and 3e are double ribs formed by sandwiching the insert member 17.

ここで、係止ピン１３，膜押圧部３２，並びに膜状部材支持部１６若しくはインサート部材１７の位置関係について、具体例を挙げると、例えば、相互に隣り合う膜押圧部３２同士の間に係止ピン１３が設けられ、また、近傍（更に言えば、直近）の係止ピン１３よりも対向面視において膜状部材設置台部１１寄りの位置（言い換えると、膜状部材２及び支持部材３の平面視において近傍（直近）の係止ピン１３よりも内側）に膜状部材支持部１６／インサート部材１７が設けられたり、近傍（更に言えば、直近）の膜押圧部３２よりも対向面視において膜状部材設置台部１１寄りの位置（言い換えると、膜状部材２及び支持部材３の平面視において近傍（直近）の膜押圧部３２よりも内側）に膜状部材支持部１６／インサート部材１７が設けられたりすることが考えられる。 Here, to give a specific example of the positional relationship between the locking pin 13, the film pressing portion 32, and the film-like member supporting portion 16 or the insert member 17, for example, the film pressing portions 32 that are adjacent to each other are engaged with each other. The stop pin 13 is provided, and the position closer to the film-like member installation base 11 (in other words, the film-like member 2 and the support member 3) in the facing plane view than the locking pin 13 in the vicinity (more specifically, the nearest). In the plan view of the above, the film-like member support portion 16 / insert member 17 is provided in the vicinity (inside the locking pin 13 in the vicinity (closest)), or the surface facing the film pressing portion 32 in the vicinity (more specifically, the nearest). Membrane-like member support portion 16 / insert at a position closer to the membrane-like member installation base 11 in view (in other words, inside the membrane-pressing portion 32 in the vicinity (closest) in plan view of the membrane-like member 2 and support member 3). It is conceivable that the member 17 is provided.

ただし、係止ピン１３，膜押圧部３２，並びに膜状部材支持部１６若しくはインサート部材１７の位置関係は上述の具体例に限定されるものではなく、他の態様で各部・部材１３，３２，１６，１７が配設されるようにしても良い。 However, the positional relationship between the locking pin 13, the film pressing portion 32, and the film-like member support portion 16 or the insert member 17 is not limited to the above-mentioned specific example, and the respective parts / members 13, 32, in other embodiments. 16 and 17 may be arranged.

なお、相互に隣り合う膜押圧部３２同士の間に係止ピン１３が設けられたり、係止ピン１３よりも内側の近傍に膜状部材支持部１６／インサート部材１７が設けられたり、或いは、膜押圧部３２よりも内側の近傍に膜状部材支持部１６／インサート部材１７が設けられたりすることにより、これらがより良く協調・協働して膜状部材２と支持部材３との一体成形が一層適切に行われる。特に、膜状部材２の仮止めの仕組みとして係止ピン１３は有用・有効である一方で当該係止ピン１３の設置箇所には膜押圧部３２を設けることができないところ、膜押圧部３２が無い箇所では支持部材３の材料の流入圧力によって膜状部材２がキャビティ１９内で動いてしまうのに対し、係止ピン１３の近傍に膜状部材支持部１６／インサート部材１７を設けることによって膜状部材２の位置を安定させることができるので膜状部材２と支持部材３との一体成形を一層適切に行うことが可能になる。 A locking pin 13 may be provided between the film pressing portions 32 adjacent to each other, or a film-like member support portion 16 / insert member 17 may be provided in the vicinity of the inside of the locking pin 13. By providing the film-like member support portion 16 / insert member 17 in the vicinity of the inner side of the film-pressing portion 32, these are better coordinated and cooperated to integrally form the film-like member 2 and the support member 3. Is done more appropriately. In particular, while the locking pin 13 is useful and effective as a mechanism for temporarily fixing the film-like member 2, the film pressing portion 32 cannot be provided at the installation location of the locking pin 13. In the absence, the film-like member 2 moves in the cavity 19 due to the inflow pressure of the material of the support member 3, whereas the film-like member support portion 16 / insert member 17 is provided in the vicinity of the locking pin 13. Since the position of the shaped member 2 can be stabilized, it becomes possible to more appropriately perform integral molding of the film-shaped member 2 and the support member 3.

以上のように構成された膜状部材支持部１６が成形溝１２内に設けられるようにしたりインサート部材１７が成形溝１２内に設置されるようにしたりした場合には、これら膜状部材支持部１６やインサート部材１７を支(つか)え／突っ支いとして機能させて成形溝１２内に於ける膜状部材２の位置を安定させることによって膜状部材２の周縁部を支持部材３の内部に確実に存在させて（別言すると、位置させて）膜状部材２の周縁部（特に、縁の端を除く、膜状部材２の平面視において縁の端よりも内側の部分）が支持部材３の表面（特に、上面や側面）に露出してしまうことを防止することができるので、不良の無い臀部支持構造物１を確実に製造することが可能になる。 When the film-like member support portion 16 configured as described above is provided in the forming groove 12 or the insert member 17 is provided in the forming groove 12, these film-like member support portions are provided. By making the 16 and the insert member 17 function as a support / support to stabilize the position of the film-like member 2 in the forming groove 12, the peripheral edge portion of the film-like member 2 is supported inside the support member 3. Supports the peripheral edge of the film-like member 2 (particularly, the part inside the edge of the film-like member 2 in the plan view, excluding the edge of the edge). Since it is possible to prevent the member 3 from being exposed to the surface (particularly, the upper surface or the side surface), it is possible to reliably manufacture the buttock support structure 1 without defects.
