Moreover, it has the retreat space part 9 which can accommodate the floating wedge member 4 of the state which is not meshing with the gear part 11b (meshing release state).

一対の浮動くさび部材４，４は、 180度の回転対称位置に配設されたくさび形窓部５，５に、各々挿通されている。浮動くさび部材４は、壁部12ａ，12ａの間隙寸法よりも僅かに大きく形成され、くさび形窓部５に挿通した状態で、壁部12ａ，12ａの外側面から両側端部を突出している。浮動くさび部材４は、一面側を歯面４ａとし、かつ、他面側にくさび面５ａに当接する円弧状の当接面４ｂを形成している。浮動くさび部材４は、浮動段付部８に当接して、ギヤ部11ｂから離間する方向に自らを誘導する誘導勾配面14を有している。誘導勾配面14は、歯面４ａの後縁部に形成されている。
一対のギヤ部11ｂ，11ｂは、壁部12ａ，12ａの間にて揺動軸心Ｌ13廻りに揺動可能に枢結されている。ギヤ部11ｂ，11ｂは、揺動片部11に貫設され浮動くさび部材４を挿通可能な逃がし窓部18，18に、揺動軸心Ｌ13を対称軸として 180度の回転対称位置に外歯状に形成されている。ギヤ部11ｂ，11ｂは、揺動片部11の基端部に応力集中が発生しにくい形状となっている。また、ギヤ部11ｂは、一端部側（噛合終点部側）に、浮動くさび部材４を退避空間部９へ押圧する押込突部15が形成され、他端部側（噛合始点部側）に、退避空間部９に収納された浮動くさび部材４を押し出す押出突部16が形成されている。 The pair of floating wedge members 4 and 4 are respectively inserted into wedge-shaped window portions 5 and 5 arranged at rotationally symmetric positions of 180 degrees. The floating wedge member 4 is formed to be slightly larger than the gap dimension between the wall portions 12a and 12a, and protrudes at both end portions from the outer surfaces of the wall portions 12a and 12a in a state of being inserted into the wedge-shaped window portion 5. The floating wedge member 4 has a tooth surface 4a on one surface side, and an arcuate contact surface 4b that contacts the wedge surface 5a on the other surface side. The floating wedge member 4 has a guiding gradient surface 14 that contacts the floating stepped portion 8 and guides itself in a direction away from the gear portion 11b. The guiding gradient surface 14 is formed at the rear edge of the tooth surface 4a.
A pair of gear portions 11b, 11b, the wall portion 12a, and is swingably pivotally connected to the pivot axis L 13 around at between 12a. Gear portion 11b, 11b has an outer floating wedge member 4 is formed through the swinging piece 11 into the insertion can escape window portions 18 and 18, the rotational symmetry at 180 degrees pivot axis L 13 as a symmetrical axis It is formed in a tooth shape. The gear portions 11b and 11b have a shape in which stress concentration is unlikely to occur at the base end portion of the swing piece portion 11. Further, the gear portion 11b is formed with a pushing projection 15 for pressing the floating wedge member 4 against the retracting space portion 9 on one end side (meshing end point side) and on the other end side (meshing start point side). An extrusion protrusion 16 is formed to push out the floating wedge member 4 accommodated in the retreat space 9.

バネ線材６は、所定長さに切断され、一文字状に形成されている。バネ線材６は、一方端を直線状とし、他方端を鉤状乃至円形状に曲げ加工して支持部17に外嵌している。バネ線材６は、当接面４ｂに接触して円弧状に弾性変形しており、浮動くさび部材４に復元力を常に弾発付勢している。
ギヤ部11ｂが揺動し、歯面４ａがギヤ部11ｂに噛合して浮動くさび部材４が移動した際に、当接面４ｂは、くさび面５ａに案内され、浮動くさび部材４をギヤ部11ｂとくさび面５ａの間にくさび状に配設させるように形成している。つまり、浮動くさび部材４は、歯面４ａがギヤ部11ｂに噛合し、かつ、当接面４ｂがくさび面５ａに当接し、ギヤ部11ｂ（揺動片部11）が、一方向（傾倒方向Ｂ）へ揺動するのを規制している。 The spring wire 6 is cut into a predetermined length and is formed in a single character. The spring wire 6 is externally fitted to the support portion 17 by bending one end into a straight line and bending the other end into a hook shape or a circular shape. The spring wire 6 is elastically deformed in an arc shape in contact with the abutting surface 4 b, and constantly restores a restoring force to the floating wedge member 4.
When the gear portion 11b swings and the tooth surface 4a meshes with the gear portion 11b and the floating wedge member 4 moves, the contact surface 4b is guided by the wedge surface 5a, and the floating wedge member 4 is guided to the gear portion 11b. It is formed so as to be arranged like a wedge between the wedge surfaces 5a. That is, in the floating wedge member 4, the tooth surface 4a meshes with the gear portion 11b, the abutment surface 4b abuts on the wedge surface 5a, and the gear portion 11b (oscillating piece portion 11) moves in one direction (tilt direction). B) is restricted from swinging.

壁部12ａ，12ａは、薄型円形状（円盤状）のカバー部材７，７によって揺動軸心Ｌ13方向から挟まれている。枢結ピン部材13は、壁部12ａ，12ａと、ギヤ部11ｂ，11ｂと、カバー部材７，７とを、同心状に枢着している。つまり、壁部12ａ，12ａと、くさび形窓部５，５，５，５と、浮動くさび部材４，４と、ギヤ部11ｂ，11ｂと、バネ線材６，６とを、組立てて、カバー部材７，７間に収納して、枢結部10が構成されている。
弾発部材２の厚さ寸法ｄは、枢結部10の厚さ寸法Ｗ0 に対して、15％〜 100％の大きさに設定している（図13参照）。弾発部材２の厚さ寸法ｄが、枢結部10の厚さ寸法Ｗ0 の15％より小さいと、弾発部材２の十分な強度及び剛性を確保できず、レスト部３の最終傾倒状態を安定して保持できない。また、弾発部材２の厚さ寸法ｄが、枢結部10の厚さ寸法Ｗ0の 100％より大きいと、角度調整金具１の幅寸法が過大となり、ソファーＳへの取付けが制限される虞がある。
なお、角度調整金具１の枢結部10の内部機構としては、（図示省略するが）爪とギヤ歯との噛合によるラチェット機構を有するものでもよく、本発明の要旨を変更しない程度であれば設計の変更が可能である。 Walls 12a, 12a is sandwiched from the oscillation axis L 13 direction by the cover member 7, 7 a thin circular (disc-shaped). The pivoting pin member 13 pivots the wall portions 12a and 12a, the gear portions 11b and 11b, and the cover members 7 and 7 concentrically. That is, the wall portions 12a, 12a, the wedge-shaped window portions 5, 5, 5, 5, the floating wedge members 4, 4, the gear portions 11b, 11b, and the spring wire members 6, 6 are assembled to form a cover member. The pivoting portion 10 is configured to be accommodated between the seven and seven.
The thickness dimension d of the elastic member 2 is set to 15% to 100% with respect to the thickness dimension W 0 of the pivoting portion 10 (see FIG. 13). If the thickness dimension d of the elastic member 2 is smaller than 15% of the thickness dimension W 0 of the pivoting portion 10, sufficient strength and rigidity of the elastic member 2 cannot be secured, and the rest portion 3 is in the final tilted state. Cannot be held stably. On the other hand, if the thickness dimension d of the elastic member 2 is larger than 100% of the thickness dimension W 0 of the pivoting part 10, the width dimension of the angle adjusting bracket 1 becomes excessive, and the attachment to the sofa S is restricted. There is a fear.
In addition, as an internal mechanism of the pivoting part 10 of the angle adjusting bracket 1, it may have a ratchet mechanism (not shown) by meshing a claw and a gear tooth, as long as the gist of the present invention is not changed. Design changes are possible.

そして、本発明の角度調整金具１は、図２〜図８の実施の形態に於て、さらに、図９〜図13の他の実施の形態に於ても、（図１に示したように、）レスト部３に取着される揺動アーム47と、固定基部40Ｆ，41Ｆ，43Ｆに固着される取付アーム46と、両アーム47，46を枢結した枢結ピン部材13とを、備えている。
上記取付アーム46は、枢結ピン部材13に基端が非回転状態として枢着された前記取付片部12と、この取付片部12の基端に固着された前記カバー部材７とを、有する。このように、カバー部材７と帯板状の取付片部12とは、（一体状として）非回転状態に連結されている。 The angle adjusting bracket 1 of the present invention is the same as the embodiment shown in FIGS. 2 to 8 and the other embodiments shown in FIGS. 9 to 13 (as shown in FIG. 1). )) A swing arm 47 attached to the rest portion 3, a mounting arm 46 fixed to the fixed base portions 40F, 41F, 43F, and a pivoting pin member 13 pivoting the arms 47, 46 are provided. ing.
The mounting arm 46 includes the mounting piece portion 12 pivotally attached to the pivoting pin member 13 in a non-rotating state, and the cover member 7 fixed to the proximal end of the mounting piece portion 12. . Thus, the cover member 7 and the strip-shaped attachment piece 12 are connected in a non-rotating state (as an integral shape).

また、揺動アーム47は、ピン部材13に基端45が枢着される揺動片部11と、レスト部３の内部フレーム49が固着されるブラケット48と、このブラケット48と揺動片部11とを連結して平行リンク機構Ｈを構成する２本の平行なリンク片34，35と、を備えている。
この平行リンク機構Ｈは、４本のピン57，58，59，60によって相互に枢結されたブラケット48と揺動片部11とリンク片34，35とから構成され、ブラケット48は常に揺動片部11と平行を保ちつつ、図２の（Ａ）（Ｂ）（Ｃ）（Ｄ）のように、揺動片部11の基端45側と先端44側の間を往復平行移動自在である。 Further, the swing arm 47 includes a swing piece portion 11 having a base end 45 pivotally attached to the pin member 13, a bracket 48 to which the inner frame 49 of the rest portion 3 is fixed, and the bracket 48 and the swing piece portion. 11 and two parallel link pieces 34 and 35 constituting the parallel link mechanism H.
This parallel link mechanism H is composed of a bracket 48, a swing piece 11 and link pieces 34, 35 that are pivotally connected to each other by four pins 57, 58, 59, 60, and the bracket 48 always swings. While maintaining parallel to the piece 11, the reciprocating parallel movement between the base end 45 side and the tip end 44 side of the swing piece 11 can be freely performed as shown in FIGS. 2 (A), (B), (C) and (D). is there.

そして、表皮皺発生防止機構50は、上記ブラケット48と、ブラケット48と揺動片部11とを連結する前記リンク片34，35と、このリンク片34，35の内の一方34とカバー部材７とを連結する連結アーム37とを、具備する。
レスト部３の起立方向Ａへの揺動に伴ってブラケット48を先端方向Ｐ―――先端44の方向―――へ移動させることで、揺動アーム47の腕の長さＬ47を、増加させる作用を、この連結アーム37が果たしている。
本発明に於て、揺動アーム47の腕の長さＬ47とは、枢結ピン部材13の軸心―――即ち、水平状揺動軸心Ｌ13―――を中心点として、ブラケット48の最先端部48Ａまでの距離（寸法）を言う。 The skin wrinkle generation preventing mechanism 50 includes the bracket 48, the link pieces 34 and 35 that connect the bracket 48 and the swing piece portion 11, one of the link pieces 34 and 35, and the cover member 7. And a connecting arm 37 for connecting the two.
The arm length L 47 of the oscillating arm 47 is increased by moving the bracket 48 in the tip direction P --- the direction of the tip 44-- as the rest 3 swings in the standing direction A. The connecting arm 37 fulfills the action of
In the present invention, the arm length L 47 of the oscillating arm 47 is the bracket centered on the axis of the pivot pin member 13 ---- that is, the horizontal oscillating axis L 13 ---. The distance (dimensions) to the 48 most advanced parts 48A.

さらに具体的に説明すると、連結アーム37は、弯曲した板片から成り、基端はピンによって薄い円盤状のカバー部材７に、揺動自在に枢着されると共に、先端はピン39によって、（枢結ピン部材13に近い側の）リンク片34の長手方向中間部に、揺動自在に枢着されている。
基端のピン38の枢着位置は、軸心Ｌ13に関して、ブラケット48の在る側とは反対側―――反先端方向―――であって、かつ、取付片部12の在る側とは反対側に、設定する。
ピン38，39を上述のように設けることで、連結アーム37は、平行リンク機構Ｈの一部を成すアーム34を揺動させて、平行リンク機構Ｈの他の一部を成すブラケット48を、先端方向Ｐへ、図２の（Ａ）→（Ｂ）→（Ｃ）のように移動させ、あるいは、図４→図５→図６→図７のように移動させ、腕の長さＬ47をしだいに増加させ、ブラケット48に固着したレスト部３の内部フレーム49を、図１中の矢印Ｐの方向へ移動させ、レスト部３の起立方向Ａへの作動時に（共通）表皮28を引張って、この表皮52に弛み皺53（図17参照）が発生することを防止する。 More specifically, the connecting arm 37 is formed of a bent plate piece, the base end is pivotally attached to the thin disc-shaped cover member 7 by a pin, and the tip is pivoted by a pin 39 ( A pivot piece is pivotally attached to an intermediate portion in the longitudinal direction of the link piece 34 (on the side close to the pivot pin member 13).
The pivot position of the pin 38 at the base end is opposite to the side where the bracket 48 is located with respect to the axis L 13 --the direction opposite to the tip--and the side where the mounting piece 12 is present. Set on the opposite side.
By providing the pins 38 and 39 as described above, the connecting arm 37 swings the arm 34 that forms a part of the parallel link mechanism H, and the bracket 48 that forms the other part of the parallel link mechanism H. the distal direction P, is moved as in Figure 2 (a) → (B) → (C), or FIG. 4 → Fig 5 → Fig. 6 → move as shown in Figure 7, the length of the arm L 47 The inner frame 49 of the rest 3 fixed to the bracket 48 is moved in the direction of arrow P in FIG. 1, and the (same) skin 28 is pulled when the rest 3 is actuated in the standing direction A. Thus, it is possible to prevent the slack wrinkle 53 (see FIG. 17) from occurring in the epidermis 52.

ところで、図２、あるいは、図４〜図７でも明らかなように、カバー部材７は薄型円盤状であって、全く円周面に突出部（突隆部）が存在せず、表皮28を内面（裏面）から傷付けることがない利点があり、さらに、ピン部材13の軸心が該当する水平状揺動軸心Ｌ13と平行な方向から見て、連結アーム37は、円盤状のカバー部材７及び揺動片部11の内の少なくとも一方とは、常時重なり合って、矢印（Ａ）（Ｂ）方向に揺動している。つまり、本発明に係る連結アーム37の弯曲状又はくの字状の（折曲状の）形状とすると共に、アーム37の寸法と、両端の枢結位置―――ピン38，39の配設位置―――を、アーム37がカバー部材７及び揺動片部11のいずれかとは常時重なって見えるように、設定することで、表皮28を内面（裏面）から傷付けることを防いでいる。 2 or 4 to 7, the cover member 7 has a thin disc shape, and there is no protrusion (protrusion) on the circumferential surface. There is an advantage that the pin member 13 is not damaged from the (back surface), and the connecting arm 37 is a disc-shaped cover member 7 when viewed from a direction parallel to the corresponding horizontal swing axis L 13. And at least one of the swinging piece portions 11 always overlaps and swings in the directions of arrows (A) and (B). That is, the connecting arm 37 according to the present invention has a curved shape or a U-shaped (folded) shape, and the dimensions of the arm 37 and the pivot positions at both ends --- the arrangement of the pins 38 and 39. By setting the position so that the arm 37 always appears to overlap with either the cover member 7 or the swing piece 11, the skin 28 is prevented from being damaged from the inner surface (back surface).

本発明の他の実施形態に関して追加説明すると、図９〜図13、及び、図１に於て、レスト部３の起立方向Ａへの揺動を抑制する回転抵抗モーメントＭを付与する弾発部材２―――具体的には渦巻きばね20―――を、カバー部材７に於ける連結アーム37の配設側面と反対側面に、付設している。これによって、図９で明らかなように、ピン部材13の軸心と平行な方向の厚さ寸法を減少できて、コンパクト化を達成している。   The elastic member which gives the rotational resistance moment M which suppresses rocking | fluctuation to the standing direction A of the rest part 3 in FIGS. 9-13 and FIG. 2—specifically, the spiral spring 20——is attached to the side surface of the cover member 7 opposite to the side surface where the connecting arm 37 is disposed. As a result, as apparent from FIG. 9, the thickness dimension in the direction parallel to the axis of the pin member 13 can be reduced, thereby achieving compactness.

そして、弾発部材２は、表皮28が何らかの荷重を受けて、最終傾倒状態のレスト部３に作用する張力に対抗して、レスト部３を最終傾倒状態にて保持できる程度の抵抗力をもって起立方向Ａへの揺動を抑制している。
なお、本発明に於て、「揺動を多段階で阻止する」とは、レスト部３を最終傾倒状態から起立方向Ａに揺動させて最終起立状態とする範囲で、等ピッチで７段階以上の姿勢保持角度を設定し、起立方向Ａに揺動したレスト部３が傾倒方向Ｂに戻らないように段階的に規制することを意味する。
これを、ヘッドレスト部30を例として、具体的に説明すれば、ヘッドレスト部30を水平姿勢とした最終傾倒状態から鉛直姿勢とする範囲で、等ピッチで例えば16段階の姿勢保持角度を設定し、前方（起立方向Ａ）に揺動したヘッドレスト部30が後方（傾倒方向Ｂ）に戻らないように段階的に規制している。あるいは、フットレスト部31を例として、具体的に説明すれば、フットレスト部31を鉛直姿勢とした最終傾倒状態から水平姿勢とする範囲で、等ピッチで例えば16段階の姿勢保持角度を設定し、上方（起立方向Ａ）に揺動したフットレスト部31が下方（傾倒方向Ｂ）に戻らないように段階的に規制している。 The elastic member 2 stands up with a resistance sufficient to hold the rest 3 in the final tilted state against the tension acting on the rest 3 in the final tilted state when the skin 28 receives some load. Oscillation in the direction A is suppressed.
In the present invention, “to prevent the swinging in multiple stages” means that the rest part 3 is swung in the standing direction A from the final tilted state to the final standing state, and is in seven stages at an equal pitch. This means that the posture holding angle is set as described above, and the rest portion 3 swinging in the standing direction A is regulated in stages so as not to return in the tilting direction B.
Specifically, taking the headrest portion 30 as an example, in the range from the final tilted state in which the headrest portion 30 is in a horizontal posture to a vertical posture, for example, 16 posture holding angles are set at an equal pitch, The headrest 30 that swings forward (standing direction A) is regulated in stages so as not to return backward (tilting direction B). Or, specifically, taking the footrest part 31 as an example, in the range from the final tilted state in which the footrest part 31 is in a vertical posture to the horizontal posture, for example, 16 posture holding angles are set at equal pitches, The footrest 31 that swings in the (standing direction A) is regulated in a stepwise manner so that it does not return downward (tilting direction B).

さらに、追加説明すると、図12と図13に示すように、レスト部３に平行リンク機構Ｈを介して取着される揺動片部11と、ソファーＳの固定側に固着される取付片部12と、取付片部12に非回転状に組立てられると共に揺動片部11と取付片部12とを枢結した枢結ピン部材13とを、備えている。枢結ピン部材13は、取付片部12に嵌合しつつ、揺動片部11を揺動軸心Ｌ13廻りに揺動自在として枢着している。枢結ピン部材13は、一端を大径のヘッド33とし、このヘッド33に揺動軸心Ｌ13方向に直交状の係止溝13ａを形成している。枢結ピン部材13の他端は、小径として、組立状態でカシメ等によって抜止めされている。
弾発部材２は、渦巻き状の金属製ゼンマイばねから成る渦巻きばね20であって、くの字状に折り曲げた外端部22を、揺動片部11の基端部寄りに突設した係止部11ａに止着し、かつ、略直角に折り曲げた内端部21を、枢結ピン部材13の係止溝13ａに止着している。渦巻きばね20は、最終傾倒状態のレスト部３に於て、緊張状態の表皮28がさらに荷重を受けても、揺動片部11の起立方向Ａへの揺動を抑制して、レスト部３が起立しない程度の抵抗力を回転抵抗モーメントＭとして弾発的に揺動片部11に付与している。 Further, as shown in FIGS. 12 and 13, the swing piece 11 attached to the rest 3 via the parallel link mechanism H, and the attachment piece fixed to the fixed side of the sofa S, as shown in FIGS. 12 and a pivot pin member 13 that is assembled to the attachment piece 12 in a non-rotating manner and pivotally connects the swing piece 11 and the attachment piece 12. The pivot pin member 13 is pivotally mounted so as to be swingable about the swing axis L 13 while being fitted to the mounting piece 12. Pivotally pin member 13, one end and a large diameter of the head 33, forming a quadrature-shaped engaging groove 13a on the head 33 to the pivot axis L 13 direction. The other end of the pivot pin member 13 has a small diameter and is secured by caulking or the like in an assembled state.
The elastic member 2 is a spiral spring 20 made of a spiral metal spring, and has an outer end 22 bent in a U-shape projecting toward the proximal end of the swing piece 11. The inner end portion 21 that is fixed to the stopper portion 11a and bent at a substantially right angle is fixed to the locking groove 13a of the pivot pin member 13. The spiral spring 20 suppresses the swinging of the swinging piece portion 11 in the standing direction A even when the tensioned skin 28 is further subjected to the load in the resting portion 3 in the final tilted state. A resistance force that does not stand up is elastically applied to the oscillating piece 11 as a rotational resistance moment M.

なお、ブラケット48の形状は、揺動片部11の長手方向から見て倒立Ｌ字型であって、上面壁には内部フレーム49を（図示省略のネジやボルトやリベット等にて）固着するための取付孔36が、図３，図９のように有し、また、鉛直壁には、ピン39が嵌入自在なＵ字状切欠凹部29を図５，図６のように有している。この切欠凹部29を有することで、ピン39が嵌入した状態で、極めてコンパクトとなる（図２Ａ，図３，図10等参照）。   The shape of the bracket 48 is an inverted L shape when viewed from the longitudinal direction of the oscillating piece 11, and an inner frame 49 is secured to the upper wall (by screws, bolts, rivets, etc., not shown). 3 and 9, and a vertical wall has a U-shaped notch recess 29 into which a pin 39 can be fitted as shown in FIGS. . By having this cut-out recess 29, the pin 39 is fitted and becomes extremely compact (see FIG. 2A, FIG. 3, FIG. 10, etc.).

上述した本発明の角度調整金具の使用方法（作用）について説明する。
まず、図１に示すソファーＳを製作する工程、又は、表皮28の張り替え作業に於て、ソファーＳの固定側からレスト部３にかけて表皮28を張設する。この際、レスト部３をソファーＳの固定側に取り付ける角度調整金具１，１は、弾発部材２による回転抵抗モーメントＭ（図10，図12参照）をもってレスト部３の起立方向Ａへの揺動を抑制する。レスト部３が最終傾倒状態を保持しつつ、表皮28に適度な緊張状態を与えて張るため、レスト部３を起立して使用する際に、表皮28に余裕が生じるが皺の発生は減少できる。本発明の図９〜図13の実施の形態では、さらに、表皮皺発生防止機構50をプラス（付加）した構成であるので、レスト部３を起立した状態で使用する際に、表皮28には、（図17のような従来の）皺53が生じないで、平滑な美しい感じを与える。 The use method (action) of the angle adjusting bracket of the present invention described above will be described.
First, the skin 28 is stretched from the fixed side of the sofa S to the rest portion 3 in the process of manufacturing the sofa S shown in FIG. At this time, the angle adjusting brackets 1 and 1 for attaching the rest part 3 to the fixed side of the sofa S have the rotational resistance moment M (see FIGS. 10 and 12) by the elastic member 2 to swing the rest part 3 in the standing direction A. Suppress movement. While the rest part 3 maintains the final tilted state, the skin 28 is given an appropriate tension and is stretched. Therefore, when the rest part 3 is used upright, there is a margin in the skin 28, but the occurrence of wrinkles can be reduced. . In the embodiment of FIG. 9 to FIG. 13 of the present invention, since the skin wrinkle generation prevention mechanism 50 is added (added), the skin 28 is not attached to the rest 28 when the rest portion 3 is used upright. , (Conventional as shown in FIG. 17) 皺 53 does not occur, giving a smooth and beautiful feeling.

次に、レスト部３を傾倒方向Ｂへ可動域限界まで、つまり、最終傾倒状態に揺動させたソファーＳに於て、人が腰掛けて座部41及び背もたれ部40に荷重がかかると、座部41の表皮28が人の荷重により沈み込み、又は、背もたれ部40の表皮28が下方へ引きずられ、レスト部３に作用する張力が増大する。この際、弾発部材２は、回転抵抗モーメントＭを抵抗力としてレスト部３の起立方向Ａへの揺動を抑制し、確実に最終傾倒状態にて保持する。   Next, when a person sits down and a load is applied to the seat portion 41 and the backrest portion 40 on the sofa S in which the rest portion 3 is swung in the tilt direction B to the limit of the movable range, that is, in the final tilted state, The epidermis 28 of the part 41 sinks due to a human load, or the epidermis 28 of the backrest part 40 is dragged downward, and the tension acting on the rest part 3 increases. At this time, the elastic member 2 suppresses the swinging of the rest portion 3 in the standing direction A using the rotational resistance moment M as a resistance force, and reliably holds it in the final tilted state.

その後、図１及び図16に示すように最終傾倒状態からレスト部３を回転抵抗モーメントＭに反して起立方向Ａに起き上がらせていく。図16（ａ）に於て、浮動くさび部材４は、歯面４ａがギヤ部11ｂに噛合し、かつ、当接面４ｂがくさび面５ａに当接している。図16（ｂ）に示すように、起立方向Ａにギヤ部11ｂを揺動させると、浮動くさび部材４の当接面４ｂは、くさび面５ａから離れて僅かな間隙ｇを生じる。図16（ｃ）に示すように、さらに起立方向Ａにレスト部３を揺動させると、浮動くさび部材４の誘導勾配面14がくさび形窓部５の浮動段付部８に当接し、歯面４ａとギヤ部11ｂとの噛合が解除され、歯面４ａがギヤ部11ｂに弾かれるようにカチカチと音を立てつつ乗り越える。レスト部３の揺動を所望の位置で停止すると、バネ線材６によって、浮動くさび部材４がギヤ部11ｂに押し付けられ、歯面４ａがギヤ部11ｂに噛合する。くさび作用によりレスト部３の傾倒方向Ｂへの揺動は規制され、所望の傾斜角度をもって保持される。   Thereafter, as shown in FIGS. 1 and 16, the rest portion 3 is raised in the standing direction A against the rotational resistance moment M from the final tilted state. In FIG. 16 (a), the floating wedge member 4 has a tooth surface 4a meshed with the gear portion 11b and a contact surface 4b in contact with the wedge surface 5a. As shown in FIG. 16 (b), when the gear portion 11b is swung in the standing direction A, the contact surface 4b of the floating wedge member 4 is separated from the wedge surface 5a to form a slight gap g. When the rest portion 3 is further swung in the standing direction A as shown in FIG. 16 (c), the guide gradient surface 14 of the floating wedge member 4 comes into contact with the floating stepped portion 8 of the wedge-shaped window portion 5, and the teeth The engagement between the surface 4a and the gear portion 11b is released, and the tooth surface 4a gets over with a clicking sound so that it is repelled by the gear portion 11b. When the swinging of the rest part 3 is stopped at a desired position, the floating wedge member 4 is pressed against the gear part 11b by the spring wire 6, and the tooth surface 4a meshes with the gear part 11b. Owing to the wedge action, the swinging of the rest portion 3 in the tilt direction B is restricted and held at a desired tilt angle.

なお、図１，図２等の図面、及び、上述の説明とは逆に、レスト部３に取付アーム46を固着し、かつ、固定基部40Ｆ，41Ｆ，43Ｆ側に揺動アーム47を取着するも、望ましい場合がある（図示省略）。即ち、揺動アーム47のブラケット48を、固定基部40Ｆ，41Ｆ，43Ｆの内部フレームに固着し、取付アーム46はレスト部３の内部フレーム49に固着する。このときには、水平状揺動軸心Ｌ13が固定基部40Ｆ，41Ｆ，43Ｆに対して略平行移動又は略円弧状移動を行うこととなるが、表皮28に弛み皺が発生することを、同様に防止できる。しかも、レスト部３の内部フレーム49に於て、取付アーム46との連結・接続部分の形状や構成を種々のものに設計変形容易となる利点がある。 1 and 2 and the above description, the mounting arm 46 is fixed to the rest 3 and the swing arm 47 is attached to the fixed bases 40F, 41F, 43F. However, it may be desirable (not shown). That is, the bracket 48 of the swing arm 47 is fixed to the inner frame of the fixed base portions 40F, 41F, 43F, and the mounting arm 46 is fixed to the inner frame 49 of the rest portion 3. At this time, horizontally pivot axis L 13 is fixed base 40F, 41F, but so that the performing substantially translation movement or a substantially arc shape with respect to 43F, that slack creasing of the skin 28, as well Can be prevented. In addition, the inner frame 49 of the rest portion 3 has an advantage that the shape and configuration of the connecting / connecting portion with the mounting arm 46 can be easily changed in design.

図15に示すように、レスト部３を所定量揺動させて最終起立状態とすると、図16（ｄ）に示すように、押込突部15が浮動くさび部材４に当接し、浮動くさび部材４を押圧する。図16（ｅ）に示すように、さらに起立方向Ａにレスト部３を揺動させると、浮動くさび部材４は、誘導勾配面14をくさび形窓部５の浮動段付部８に摺接しつつ退避空間部９に案内（誘導）される。浮動くさび部材４が退避空間部９に収納される（図８が対応する）と、歯面４ａとギヤ部11ｂの噛合は解除され、傾倒方向Ｂへの揺動が自由になる。そして、図16（ｆ）に示すように、レスト部３を傾倒方向Ｂへ揺動し、最終傾倒状態まで復元すると、押出突部16が浮動くさび部材4に当接し、浮動くさび部材4を退避空間部9から押し出す。このようにして、再び図16（ａ）に示す状態として、歯面４ａがギヤ部11ｂに噛合し、レスト部３の傾倒方向Ｂへの揺動を規制する。   As shown in FIG. 15, when the rest portion 3 is swung by a predetermined amount to be in the final standing state, the pushing projection 15 abuts on the floating wedge member 4 as shown in FIG. Press. As shown in FIG. 16 (e), when the rest portion 3 is further swung in the standing direction A, the floating wedge member 4 is in sliding contact with the floating stepped portion 8 of the wedge-shaped window portion 5 on the guiding gradient surface 14. Guided (guided) to the retreat space 9. When the floating wedge member 4 is accommodated in the retreat space portion 9 (corresponding to FIG. 8), the meshing between the tooth surface 4a and the gear portion 11b is released, and swinging in the tilt direction B becomes free. Then, as shown in FIG. 16 (f), when the rest portion 3 is swung in the tilt direction B and restored to the final tilted state, the push-out projection 16 comes into contact with the floating wedge member 4, and the floating wedge member 4 is retracted. Extrude from space 9 In this way, as shown in FIG. 16A again, the tooth surface 4a meshes with the gear portion 11b and restricts the swinging of the rest portion 3 in the tilt direction B.

なお、角度調整金具１がレスト部３の傾動方向Ｂへの揺動を阻止する段数としては、７段以上の段数―――これを本発明では「多段階」という―――にて阻止して所望の傾斜角度に保持する場合を主として説明したが、本発明では、この段数を、２段〜６段の複数段とするも、自由であり、さらには、１段（単段）とすることも可能である。   The number of steps that the angle adjusting bracket 1 prevents the rest 3 from swinging in the tilting direction B is prevented by seven or more steps, which is referred to as “multi-step” in the present invention. However, in the present invention, the number of steps may be set to a plurality of steps of 2 to 6, but may be freely set, and moreover, it may be set to one step (single step). It is also possible.

以上のように、本発明は、リクライニングするレスト部３を備えたソファーＳに用いられ、レスト部３の起立方向Ａへの揺動を可能としつつ傾倒方向Ｂへの揺動を阻止して所望の傾斜角度で保持する角度調整金具に於て、レスト部３の起立方向Ａへの揺動を抑制する回転抵抗モーメントＭを付与する弾発部材２を設けたので、回転抵抗モーメントＭによりレスト部３がソファーＳの表皮28に引っ張られて起立方向Ａへ揺動するのを防止でき、レスト部３を最終傾倒状態としてソファーＳを使用する際にも、レスト部３が不意に起き上がることがなく、安定して姿勢を保持できる。また、最終傾倒状態までレスト部３を倒した姿勢を保持しながら表皮28に適当な張力をもたせて張設することができ、レスト部３を起立状態として使用する際にも、表皮28が不要に弛むことがなく見栄え良く製作できる。   As described above, the present invention is used in the sofa S having the reclining rest portion 3 and is desired to prevent the rest portion 3 from swinging in the tilting direction B while allowing the rest portion 3 to swing in the standing direction A.
