Description

【０００１】
【発明の属する技術分野】
この発明は、椅子や車の座席、寝台等（以下座席等という）のクッションのフレームへの組バネの取付用フックに関するものである。
【０００２】
【従来の技術】
従来、座席等のクッションは、図７に示すように、鋼線よりなる複数のＳ字バネ１を平行に並べ、それらに中張２を直角に配し、Ｓ字バネ１と中張２とを係止して組バネ３を形成し、組バネ３を鋼製のフレーム４に鋼線よりなるダブルフック５で係止している。
【０００３】
ダブルフック５は、図８に示すように、鋼線の中央部６の両側を同方向、かつ、直角方向に、曲げて曲部７、７を形成し、更に反転させてその平行部８、８とし、その端部を曲げてフック９、９としたものである。
【０００４】
このダブルフック５による組バネ３のフレーム４への係止は図９に示すとおりに行う。
すなわち、フレーム４には、ダブルフック５の２つのフック部９、９の間隔よりも少し狭い間隔で、フック部９の先端部を挿入しうる２つの孔１０、１０が設けられており、Ｓ字バネ１の端部１ａをダブルフック５の曲部７、７内に懸け、２つのフック部９、９を指で押してその間隔を狭めてフレーム４の２つの孔１０、１０の間隔に合わせてフック部９、９の先端部を孔１０、１０に挿入し、指を離すと、フック部９、９に弾力で元の間隔に拡がろうとする力が働き、Ｓ字バネ１とフレーム４とが強く係合する。
【０００５】
【発明が解決しようとする課題】
従来のダブルフックは、鋼線で出来ているので、組バネに体重がかかると金属製のフレームと鋼線よりなるＳ字バネの端部との係止接点における摩擦で、音鳴りがして耳障りである。また、摩擦で摩耗し易く、腐食したり錆たりし、耐久性に問題がある。
更に、ダブルフックとフレームとの係止は、フレームの孔にダブルフックの鋼線のフック部が挿入されているだけであるので、孔の縁部と鋼線との摩擦でフック部が摩耗し、破損し易く、フレームとＳ字バネの係止が損なわれ易すく、耐久性に問題がある。
ダブルフックのフレームへの係止は、指先で２つのフック部の間隔を狭めなければならず、指先に力を必要とする。
【０００６】
この発明は、Ｓ字バネおよびフレームの接触が滑らかで、組バネに体重がかかっても音鳴りがせず、腐食や錆が発生せず、フレームとの係止も確実、強固で、耐久性に優れ、フレームへの取付けも簡単で容易なフックを提供することを目的とする。
【０００７】
【課題を解決するための手段】
座席等のクッションのフレームの直径に等しい直径のプラスチック製の円筒を横にし、下方の側部を軸線に沿って、直径よりも狭い幅で切除し、該切除による間隔部を設けた本体の、前記間隔部の一方の縁部に座席等のクッションの組バネのＳバネの端部の係止部を設け、前記本体の内面に、前記フレームに設けた孔に挿入または嵌入できる突部を設けてフックを形成し、前記フック２個のそれぞれの係止部に前記Ｓバネの両端を個別に係止し、それぞれのフックの本体の間隔部を前記フレームに対向してフックを押し、フック本体内に前記フレームを嵌入させ、前記突部を前記フレームの孔に挿入または嵌入させ、前記Ｓバネをフレームに張設することを可能とする。
【０００８】
前記フック本体の係止部を、本体の間隔部の一方の縁に連続し、本体の外面に沿って立ち上った爪部を有し、本体外面と前記爪部とでＳバネの端部を挿入しうる湾入部を形成したものとする。
【０００９】
または、前記フック本体の係止部を、本体の間隔部の一方の縁に連続し、本体の外面に沿って立ち上がり、その先端部が外方向に曲がり、その曲がり部内面にＳバネの端部を嵌合させて係止可能とする鋼製とする。
【００１０】
または、前記フック本体の係止部を、本体の間隔部の一方の縁部外面に該間隔部の縁に平行の突部を設け、該突部に前記縁に平行の貫通孔を設けてなり、該貫通孔にＳバネの端部を挿入することを可能とする鋼製とする。
【００１１】
本体内面の突部を、本体の間隔部の、係止部を設けた側の縁との間の円弧の長さが、他方の縁との間の円弧の長さより短い位置に設け、本体の軸線方向に突出させるのが好ましい。
【００１２】
【発明の実施の形態】
この発明の実施の形態を図面により説明する。
鋼線またはプラスチック線よりなる複数のＳ字バネ１を平行にして１または複数の中張２で組み合わせてなる組バネ３を形成する。
【００１３】
組バネ３をフレーム４に取付けるフック１１はプラスチックよりなり、フレーム４を抱持する本体１２と、Ｓ字バネ１の端部を係止する爪部１３と、フレーム４の孔に挿入する本体１２の内面に設けた係止用の突部１４とよりなる。
【００１４】
本体１２は筒体を横にして下部を軸線に沿って、すなわち軸線に平行に、削いで間隔部１５を設けたＣを下に向けた形状で、爪部１３は間隔部１５の一方の縁部に連続し、図２に示すように、上方へ（図において）反転させてＳ字バネ１の端部を抱持できる湾入部１６を形成する。
本体１２の内面には１または２個の突部１４を設ける。
突部１４は、間隔部１５の中心を直角に通る線よりも少し爪部１３側に片寄り本体の中心軸方向に突出するのが好ましい。
すなわち、図３に示すように、本体１２の間隔部１５の縁で、爪部側の縁１２ａと突部１４との間の円弧の長さは、縁１２ａと対向する縁１２ｂと突部１４との間の円弧の長さよりも短くするのが好ましい。
【００１５】
間隔部１５の幅は、フレーム４の直径よりも少し狭く、本体１２をフレーム４に押しつけると、本体１２の弾性で間隔が拡がってフレーム４が本体１２内に嵌入し、再び弾性で間隔が元に帰り、本体１２がフレーム４を抱持する。
【００１６】
フレーム４には、フック１１の突部１４を挿入または嵌入しうる孔（図示省略）を設ける。
【００１７】
このフック１１は次のように使用する。
すなわち、組バネ３のＳバネ１の両端部のそれぞれを２つのフック１１のそれぞれの湾入部１６に挿入し、先ず一方のフック１１の間隔部１５をフレーム４に対向させた後フック１１をフレーム４に押しつけると、フレーム４が本体１２内に嵌合し、多少フック１１を滑らせることにより突部１４をフレーム４の孔に対向させ、フック１１を押すと突部１４はフレーム４の孔に挿入または嵌入し、フック１１の本体１２がフレーム４を抱持して固定する。
【００１８】
次いで、もう一方のＳバネ１の端部を係止したフック１１を少々引っ張ってＳバネ１を伸ばし気味にしてフック１１の本体１２の間隔部１５を、先にもう一方のフック１１を取付けたフレーム４の対向する辺に対向させて本体１２をフレーム４に押しつけるとフレーム４が本体１２内に嵌合し、先と同様の要領で突部１４をフレーム４の孔に挿入または嵌入させる。フック１１の本体１２がフレーム４を抱持して固定する。
Ｓバネ１は弾力で少々縮もうとするので、Ｓバネ１は２つのフック１１を引き、Ｓバネ１がフック１１を介してフレーム４に強固に、かつ、弾力的に支持される。
【００１９】
次いで、組バネ３の複数のＳバネ１を上記の手順で順次フック１１を介してフレーム４に係止して、座席等のクッションを構成する。
【００２０】
組バネ取付用フックの他の実施の形態を図５に示す。
フック１１ａの本体の構成は、先の実施の形態のフックの本体１２と同じで、本体１２の内面に、同様に突部１４を設ける。
Ｓバネ１の端部の係止部の爪部１３による湾入部１６は、爪部１３が反転して出来る上方向に開いたものであるが、フック１１ａにおいては、爪部１３ａが上方から下向きに曲がり、湾入部１６ａはその曲がりの内面にあり、下方向に開いたものである。
【００２１】
このフック１１ａの使用は、組バネ３のＳバネ１の両端部のそれぞれを２つのフック１１ａそれぞれの湾入部１６ａに挿入し、その後はフック１１について先に説明したのと同じ要領で組バネ３の複数のＳバネ１を順次フック１１ａを介してフレーム４に係止して、座席等のクッションを構成する。
【００２２】
組バネ取付用フックの他の実施の形態を図６に示す。
フック１１ｂの本体の構成は先の実施の形態のフック本体１２と同じで、本体１２の内面に同様に突部１４を設ける。
Ｓバネ１の端部係止部の爪部１３の代わりに、本体１２の外面で爪部１３と同じ位置に、本体１２の中心軸に沿って、即ち、平行に、長手の突部１３ｂを設け、その突部１３ｂ内に、縁１２ａに平行の貫通孔１６ｂを設ける。貫通孔１６ｂの直径は、Ｓバネ１の端部を挿入しうる大きさとする。
【００２３】
このフック１１ｂの使用も、組バネ３のＳバネ１の両端部のそれぞれを２つのフック１１ｂのそれぞれの貫通孔１６ｂに挿入し、その後はフック１１について先に説明したのと同じ要領で、組バネ３の複数のＳバネ１を順次フック１１ｂを介してフレーム４に係止し、座席等のクッションを構成する。
【００２４】
上記各フックの本体１２の突部１４の位置は、図４に示す突部１４ａのように、１２ａと突部１４ａとの間の円弧の長さが、１２ｂと突部１４ａとの間の円弧の長さと等しくてもよいが、この長さが等しいと、Ｓバネ１に負荷（体重）がかかると、本体に爪部１３方向への力がかかり爪部１３方向へ回動しようとし、突部１４ａがフレーム４の孔から抜けてフックがフレーム４から外れるおそれがある。
【００２５】
そこで、図３に示すように、１２ｂと突部１４との間の円弧の長さを、１２ａと突部１４との間の円弧の長さよりも長くする。すなわち、突部１４の位置を少し爪部１３、１３ａ、突部１３ｂ寄りにする。そして、突部１４を軸線方向に向ける。
【００２６】
この構成により組バネ３に負荷がかかって、本体１２のＳバネ端部の係止部、すなわち、爪部１３、１３ａまたは突部１３ｂ方向へ回動しようとする力がかかっても、突部１４は斜めに軸線方向に向いているので、突部１４に軸線方向へ力が加わり、突部１４が抜けず、フック１１がフレームより脱落しない。
【００２７】
【発明の効果】
この発明に係るフックは、合成樹脂製で、フレームやＳバネとは面接触しているので摩擦係数が小さく接触部が滑らかで、かつ、音鳴りがしない。
また、合成樹脂製であるので、腐食や錆の発生がなく、摩擦係数も小さいので耐久性に優れている。
更に、座席等のクッションのフレームへの装着は、押すことによる一動作で行うことが出来、装着が簡単である。
フック本体の突部の位置を爪部側に寄せたフックは、クッションの組バネに負荷がかかっても、突部が抜けず、フックがフレームより脱落せず、フレームと組バネとの係合が強固である。

BACKGROUND OF THE INVENTION
The present invention relates to a hook for attaching a set spring to a frame of a cushion of a chair, a car seat, a bed, etc. (hereinafter referred to as a seat).
[0002]
[Prior art]
Conventionally, as shown in FIG. 7, a cushion such as a seat has a plurality of S-shaped springs 1 made of steel wires arranged in parallel, and a middle tension 2 is arranged at a right angle to the S-shaped spring 1 and the middle tension 2. Are assembled to form a combined spring 3, and the combined spring 3 is locked to a steel frame 4 with a double hook 5 made of steel wire.
[0003]
As shown in FIG. 8, the double hook 5 is bent at both sides of the central portion 6 of the steel wire in the same direction and at a right angle to form curved portions 7, 7, and further inverted so that the parallel portion 8, 8 and the end portions thereof are bent to form hooks 9 and 9.
[0004]
Locking of the assembled spring 3 to the frame 4 by the double hook 5 is performed as shown in FIG.
That is, the frame 4 is provided with two holes 10 and 10 into which the tip end portions of the hook portions 9 can be inserted at intervals slightly smaller than the interval between the two hook portions 9 and 9 of the double hook 5. The end 1a of the spring 1 is hung in the curved portions 7 and 7 of the double hook 5 and the two hook portions 9 and 9 are pushed with a finger to narrow the interval to match the interval between the two holes 10 and 10 of the frame 4. When the tip portions of the hook portions 9 and 9 are inserted into the holes 10 and 10 and the fingers are released, a force is applied to the hook portions 9 and 9 to expand to the original interval by elasticity, and the S-shaped spring 1 and the frame 4 And engage strongly.
[0005]
[Problems to be solved by the invention]
Since the conventional double hook is made of steel wire, when the weight is applied to the assembly spring, it makes a noise due to friction at the contact point between the metal frame and the end of the S-shaped spring made of steel wire. It is harsh. In addition, they are easily worn by friction, corrode and rust, and have a problem with durability.
Furthermore, since the hook of the steel wire of the double hook is only inserted into the hole of the frame, the hook portion is worn by the friction between the edge of the hole and the steel wire. It is easy to break, the engagement between the frame and the S-shaped spring is easily damaged, and there is a problem in durability.
In order to lock the double hook to the frame, the distance between the two hook portions must be reduced at the fingertip, and a force is required for the fingertip.
[0006]
This invention has a smooth contact with the S-shaped spring and the frame, does not sound even when weight is applied to the assembled spring, does not generate corrosion or rust, is securely locked with the frame, strong and durable An object of the present invention is to provide a hook that is excellent in ease and can be easily attached to a frame.
[0007]
[Means for Solving the Problems]
A plastic cylinder having a diameter equal to the diameter of the frame of a cushion such as a seat is laid sideways, and the lower side portion is cut along the axis with a width narrower than the diameter, and a space portion is provided by the cutting. A locking portion of an end of an S spring of a combined spring of a cushion such as a seat is provided on one edge of the spacing portion, and a protrusion that can be inserted or fitted into a hole provided in the frame is provided on the inner surface of the main body. Hooks are formed, and both ends of the S spring are individually locked to the respective hooks of the two hooks, and the hooks are pressed against the frame at the interval portions of the main bodies of the hooks. The frame is inserted into the frame, the protrusion is inserted or inserted into a hole of the frame, and the S spring can be stretched on the frame.
[0008]
The hook part has a claw part that is continuous with one edge of the gap part of the main body and rises along the outer surface of the main body, and the end of the S spring is inserted between the main body outer surface and the claw part. It is assumed that Shiru Bay Entrance is formed.
[0009]
Alternatively, the engaging portion of the hook main body is continued to one edge of the interval portion of the main body, rises along the outer surface of the main body, the tip portion bends outward, and the end of the S spring is formed on the inner surface of the bent portion. It is made of steel that can be locked by fitting.
[0010]
Alternatively, the hook portion of the hook body is provided with a protrusion parallel to the edge of the interval portion on the outer surface of one edge portion of the interval portion of the main body, and a through hole parallel to the edge is provided in the protrusion. The end of the S spring can be inserted into the through hole.
[0011]
The protrusion on the inner surface of the main body is provided at a position where the length of the arc between the gap portion of the main body and the edge on the side where the locking portion is provided is shorter than the length of the arc between the other edge, It is preferable to project in the axial direction.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
A combination spring 3 is formed by combining a plurality of S-shaped springs 1 made of steel wire or plastic wire in parallel with one or a plurality of intermediate tensions 2.
[0013]
A hook 11 for attaching the assembled spring 3 to the frame 4 is made of plastic, and a main body 12 that holds the frame 4, a claw portion 13 that locks the end of the S-shaped spring 1, and a main body 12 that is inserted into the hole of the frame 4. And an engaging protrusion 14 provided on the inner surface of the member.
[0014]
The main body 12 has a cylindrical body and a lower portion along the axis, that is, parallel to the axis, and is shaped by cutting C with a gap portion 15 facing downward, and the claw portion 13 has one edge of the gap portion 15. As shown in FIG. 2, a bay portion 16 that can be inverted (in the drawing) and can hold the end of the S-shaped spring 1 is formed.
One or two protrusions 14 are provided on the inner surface of the main body 12.
The protrusion 14 preferably protrudes in the direction of the central axis of the offset main body slightly toward the claw 13 than the line passing through the center of the interval portion 15 at a right angle.
That is, as shown in FIG. 3, the length of the arc between the edge 12 a on the claw side and the protrusion 14 at the edge of the spacing portion 15 of the main body 12 is the edge 12 b and the protrusion 14 facing the edge 12 a. It is preferable to make it shorter than the length of the arc between them.
[0015]
The width of the gap 15 is slightly narrower than the diameter of the frame 4. When the main body 12 is pressed against the frame 4, the gap is expanded by the elasticity of the main body 12, and the frame 4 is inserted into the main body 12. Returning to step 1, the main body 12 holds the frame 4.
[0016]
The frame 4 is provided with a hole (not shown) into which the protrusion 14 of the hook 11 can be inserted or fitted.
[0017]
This hook 11 is used as follows.
That is, the both end portions of the S spring 1 of the assembled spring 3 are inserted into the baying portions 16 of the two hooks 11, and first the spacing portion 15 of one hook 11 is opposed to the frame 4, and then the hook 11 is 4, the frame 4 fits in the main body 12, and the protrusion 11 is opposed to the hole of the frame 4 by sliding the hook 11 slightly. When the hook 11 is pressed, the protrusion 14 is inserted into the hole of the frame 4. Inserted or inserted, the main body 12 of the hook 11 holds and fixes the frame 4.
[0018]
Next, the hook 11 that locked the end of the other S spring 1 was pulled slightly to extend the S spring 1, and the interval portion 15 of the main body 12 of the hook 11 was attached, and the other hook 11 was attached first. When the main body 12 is pressed against the frame 4 so as to face the opposite sides of the frame 4, the frame 4 is fitted into the main body 12, and the protrusions 14 are inserted into or inserted into the holes of the frame 4 in the same manner as described above. The main body 12 of the hook 11 holds and fixes the frame 4.
Since the S spring 1 tends to shrink slightly due to elasticity, the S spring 1 pulls the two hooks 11, and the S spring 1 is firmly and elastically supported by the frame 4 via the hooks 11.
[0019]
Next, a plurality of S springs 1 of the assembled spring 3 are sequentially locked to the frame 4 via the hooks 11 in the above-described procedure to constitute a cushion such as a seat.
[0020]
Another embodiment of the assembled spring mounting hook is shown in FIG.
The configuration of the main body of the hook 11a is the same as that of the main body 12 of the hook of the previous embodiment, and a protrusion 14 is similarly provided on the inner surface of the main body 12.
The baying part 16 by the claw part 13 of the locking part at the end of the S spring 1 is opened upward as the claw part 13 is reversed, but in the hook 11a, the claw part 13a is directed downward from above. The bay entrance 16a is on the inner surface of the bend and opens downward.
[0021]
The hook 11a is used by inserting both ends of the S spring 1 of the assembled spring 3 into the baying portions 16a of the two hooks 11a, and thereafter performing the same procedure as described above for the hook 11. A plurality of S springs 1 are sequentially locked to the frame 4 via the hooks 11a to constitute a cushion such as a seat.
[0022]
Another embodiment of the assembled spring mounting hook is shown in FIG.
The configuration of the main body of the hook 11b is the same as that of the hook main body 12 of the previous embodiment, and the protrusion 14 is similarly provided on the inner surface of the main body 12.
Instead of the claw portion 13 of the end locking portion of the S spring 1, a long protrusion 13b is formed on the outer surface of the main body 12 at the same position as the claw portion 13 along the central axis of the main body 12, that is, in parallel. And a through hole 16b parallel to the edge 12a is provided in the protrusion 13b. The diameter of the through hole 16b is set to a size that allows the end of the S spring 1 to be inserted.
[0023]
The hook 11b is also used by inserting both ends of the S spring 1 of the assembled spring 3 into the respective through holes 16b of the two hooks 11b. A plurality of S springs 1 of the spring 3 are sequentially locked to the frame 4 via hooks 11b to constitute a cushion such as a seat.
[0024]
The position of the protrusion 14 of the main body 12 of each hook is such that the length of the arc between 12a and the protrusion 14a is the arc between 12b and the protrusion 14a, as in the protrusion 14a shown in FIG. However, if this length is equal, if a load (weight) is applied to the S spring 1, a force is applied to the main body toward the claw 13 and it tries to rotate in the direction of the claw 13 and There is a possibility that the portion 14 a comes out of the hole of the frame 4 and the hook is detached from the frame 4.
[0025]
Therefore, as shown in FIG. 3, the length of the arc between 12b and the protrusion 14 is made longer than the length of the arc between 12a and the protrusion 14. That is, the position of the protrusion 14 is slightly closer to the claw parts 13 and 13a and the protrusion 13b. Then, the protrusion 14 is directed in the axial direction.
[0026]
Even if a load is applied to the assembled spring 3 by this configuration and a force to rotate in the direction of the locking portion of the S spring end of the main body 12, that is, the claw portions 13, 13 a or the protruding portion 13 b is applied, the protruding portion Since 14 is inclined in the axial direction, force is applied to the protrusion 14 in the axial direction, the protrusion 14 does not come off, and the hook 11 does not fall off the frame.
[0027]
【The invention's effect】
The hook according to the present invention is made of synthetic resin and is in surface contact with the frame and the S spring, so that the friction coefficient is small, the contact portion is smooth, and no sound is produced.
Further, since it is made of synthetic resin, it does not generate corrosion or rust, and has a small friction coefficient, so it has excellent durability.
Furthermore, the mounting of a cushion such as a seat on the frame can be performed by a single operation by pushing, and the mounting is simple.
When the hook of the hook body is moved toward the claw, the hook does not come off even if a load is applied to the cushion assembly spring, and the hook does not fall off the frame. Is strong.
