【従来の技術】[Prior art]

従来のクーハンは図１６に示すように、ベッドＰ１と枠材Ｐ２とが起倒杆Ｐ４と垂下杆Ｐ５からなる起倒部材Ｐ３によって連結されている。起倒杆Ｐ４は、一枚のベッドＰ１の底面に取着した軸受Ｐ７に揺動可能に軸支され、その先端部Ｐ８が枠材Ｐ２に揺動自在に軸支されている垂下杆Ｐ５の中間部とピンＰ９で連結されている。ピンＰ９から下方に伸びている延長部Ｐ１０の先端が内側に折曲形成されていて、起倒杆Ｐ４が起立したとき、その折曲部Ｐ１１が起倒杆Ｐ４に当接して、起倒杆Ｐ４と垂下杆Ｐ５が一本の棒のようになって枠材Ｐ２を支持している（図１６の実線で示す状態）。起立状態の起倒杆Ｐ４と垂下杆Ｐ５がピンＰ９で折れて倒れないようにするために、垂下杆Ｐ５の延長部Ｐ１０と起倒杆Ｐ４を囲むようにビニールパイプＰ６が嵌めてある。斯かる構成の前後左右の４個の起倒部材Ｐ３によって、枠材Ｐ２がベッドＰ１から所定高さの上昇位置に保持されている。 In the conventional Kuhan, as shown in FIG. 16, a bed P1 and a frame member P2 are connected by a raising member P3 including a raising rod P4 and a hanging rod P5. The tilting rod P4 is swingably supported by a bearing P7 attached to the bottom surface of one bed P1, and the tip end P8 thereof is swingably supported by the frame member P2. Is connected to the middle part of the pin P9. When the tip of the extension portion P10 extending downward from the pin P9 is bent inward and the raising / lowering rod P4 is erected, the bending portion P11 contacts the raising / lowering rod P4 to raise and lower it. The rod P4 and the hanging rod P5 support the frame member P2 like a single rod (state shown by the solid line in FIG. 16). In order to prevent the standing rod P4 and the hanging rod P5 from being bent at the pin P9 so as not to fall down, a vinyl pipe P6 is fitted so as to surround the extension P10 of the hanging rod P5 and the raising rod P4. The frame member P2 is held at a predetermined height from the bed P1 by the four tilting members P3 on the front, rear, left and right sides.

【０００３】従って、枠材をベッドＰ１の周囲を囲む下降位置に下ろすときには、ビニールパイプＰ６を１個づつピンＰ９の上方へ抜き上げてから起倒杆Ｐ４を図９の仮想線で図示したように倒すことによって、枠材Ｐ２を下降させている。クーハンは、既知のようにベッドＰ１を包んだ囲い布Ｐ１３が枠材Ｐ２の全周に縫いつけてあり、ベッドＰ１の周囲は囲い布Ｐ１３で囲まれている。従来のクーハンは、枠材Ｐ２をベッドＰ１から所定高さの上昇位置からベッドＰ１の周囲を囲む下降位置に移動することによって、その囲い布Ｐ１３を折り畳んでベッドＰ１の高さ以下にして、寝ている赤ん坊に微風が直接あたるようにしていた。Therefore, when lowering the frame member to the lowered position surrounding the bed P1, the vinyl rods P6 are pulled out above the pins P9 one by one, and then the raising and lowering rod P4 is shown by the phantom line in FIG. The frame member P2 is lowered by tilting it down. In the Kuhan, as is known, a surrounding cloth P13 enclosing the bed P1 is sewn around the entire circumference of the frame member P2, and the circumference of the bed P1 is surrounded by the surrounding cloth P13. In the conventional couhan, the frame material P2 is moved from the bed P1 from a raised position at a predetermined height to a lowered position surrounding the bed P1 to fold the surrounding cloth P13 to a height equal to or lower than the bed P1. The breeze was applied directly to the sleeping baby.

It may be formed in a piece shape by a plate material such as a plate. When the bar material is bent, it may be bent into a substantially U-shape or a substantially V-shape to form a flat shape.

【００１２】[0012]

【作用】[Action]

請求項１のクーハンでは、上昇位置で使用していた枠材を下降位置に移動させ、起立していた起倒部材を揺動させて略水平状態に倒すと、枠材がベッドの周囲を囲んでベッドの高さ以下の偏平な状態のクーハンになる。次に、前側枠材と後側枠材が重なるように枠材を二つ折りにすると、枠材の折り畳みにつれてベッドも同時に二つ折りに折り畳まれる。そして、このように二つ折にされたクーハンは、全長が略１／２となってコンパクトになる。 According to the first aspect of the present invention, when the frame member used in the raised position is moved to the lowered position and the upright member that is upright is swung to bring it to a substantially horizontal state, the frame member surrounds the bed. It becomes a flat state below the bed height. Next, when the frame member is folded in two so that the front frame member and the rear frame member overlap, the bed is also folded in half at the same time as the frame member is folded. Then, the Coohan folded in two in this way becomes compact with its total length being approximately 1/2.

【００１３】また、請求項２の考案のクーハンにおいては、上昇位置で使用していた枠材を下降位置に移動すると、枠材上に設けられている連結部材が、複数の起倒部材のガイド部に沿って摺動して下降するので、起立していた複数の起倒部材が同時に倒れて行き、枠材がベッドの周囲を囲む下降位置に来ると、複数の起倒部材のガイド部は略水平状態に倒伏する。略水平状態に倒伏した起倒部材はベッドの高さ以下にすることができる。従って、枠材を下降位置に移動したときには枠材がベッドの周囲を囲んでベッドの高さ以下の偏平な状態のクーハンになる。According to the second aspect of the present invention, when the frame member used at the raised position is moved to the lowered position, the connecting member provided on the frame member guides the plurality of up and down members. As it slides down along the bed, it descends at the same time, and when the frame members reach the descending position that surrounds the bed, the guides of the multiple tilting members fall. Lay down almost horizontally. The raising and lowering member which is laid down in a substantially horizontal state can be set to be lower than the bed height. Therefore, when the frame material is moved to the lowered position, the frame material surrounds the periphery of the bed, and becomes a flat Kuhn below the bed height.

【００１４】一方、下降位置の枠材を上昇位置へ移動すると、枠材上に設けられている連結部材が複数の起倒部材のガイド部に沿って上昇するので、倒伏していた複数の起倒部材が同時に起立して行き、枠材が上昇位置に来ると、複数の起倒部材が起立状態になって枠材をその位置に保持する。On the other hand, when the frame member in the lowered position is moved to the raised position, the connecting member provided on the frame member rises along the guide portions of the plurality of raising / lowering members. When the inclining members stand up at the same time and the frame member reaches the elevated position, the plurality of inclining members stand up and hold the frame member in that position.

【００１５】従って、この請求項２にクーハンによれば、枠材を手で押す等して上下に移動させるだけで、容易に枠材を上昇位置および下降位置に移動させることができ、容易にクーハンを畳んだり組立てたりすることができる。また、請求項３のクーハンにおいては、枠材が上昇位置にある場合に、枠材と起倒部材とが枠材係止手段によって連結される。つまり、枠材は、枠材係止手段によって起倒部材と連結されて上昇位置に保たれる。一方、枠材係止手段による枠材と起倒部材との連結を外せば、枠材を下降位置に移動させることができる。そして、枠材が上昇位置にある場合、枠材係止手段によって、枠材に直交し且つ水平方向（即ち、ベッドに対して水平な方向）に延びる軸回りの枠材の回転が規制される。よって、上昇位置にある枠材が、ピン連結された部分（前側枠材と後側枠材の連結部分）で折れ曲がってがたつくことがない。Therefore, according to the second aspect of the present invention, it is possible to easily move the frame member to the ascending position and the descending position only by pushing the frame member by hand or the like and moving it vertically. Kuhan can be folded and assembled. According to the third aspect of the present invention, when the frame member is in the raised position, the frame member and the tilting member are connected by the frame member locking means. That is, the frame member is connected to the raising and lowering member by the frame member locking means and is kept in the raised position. On the other hand, the frame member can be moved to the lowered position by removing the connection between the frame member and the tilting member by the frame member locking means. Then, when the frame member is in the raised position, the frame member locking means regulates the rotation of the frame member about an axis extending in the horizontal direction (that is, the direction horizontal to the bed) orthogonal to the frame member. It Therefore, the frame member in the raised position does not bend and rattle at the pin-connected portion (the connecting portion between the front frame member and the rear frame member).

【００１６】また、請求項４の考案では、起倒部材に設けられた扁平状の嵌合部を、枠材に設けられた長孔に嵌合させて、枠材と起倒部材を連結する。これにより、枠材が上昇位置に保たれるとともに、枠材に直交し且つ水平方向に延びる軸回りの枠材の回転が規制される。Further, in the invention of claim 4, the flat fitting portion provided on the raising and lowering member is fitted into the long hole provided on the frame member to connect the frame member and the raising and lowering member. . As a result, the frame member is kept in the raised position, and rotation of the frame member around the axis orthogonal to the frame member and extending in the horizontal direction is restricted.

【００１７】また、請求項５の考案では、棒材の先端部を略Ｕ字状に折曲げて扁平状の嵌合部を形成しているので、製作が容易でしかも材料費がかからず、製造コストを低く抑えることができる。また、請求項６の考案では、略Ｕ字状の嵌合部の曲折部分が枠材の内側、即ちクーハンの内側に向いているので、嵌合部の先端部分によってクーハンの中の赤ん坊が傷つけられることがなく、安全性が高くなる。Further, according to the invention of claim 5, since the flat fitting portion is formed by bending the tip end portion of the bar material into a substantially U shape, the manufacturing is easy and the material cost is low. The manufacturing cost can be kept low. Further, in the invention of claim 6, since the bent portion of the substantially U-shaped fitting portion faces the inside of the frame member, that is, the inside of the coohan, the tip of the fitting portion causes the red bob in the cohan. Is not damaged and the safety is improved.

【００１８】また、請求項７の考案では、枠材係止手段として起倒部材に設けられた挾持部の上側部と下側部とで枠材を挾持する。そして、この挾持部の上側部と下側部の内の少なくとも一方が扁平状とされているので、請求項３の場合と同様に、枠材に直交し且つ水平方向に延びる軸回りの枠材の回転が規制される。よって、上昇位置にある枠材が、ピン連結された部分で折れ曲がってがたつくことがない。Further, in the invention of claim 7, the frame member is held by the upper side and the lower side of the holding portion provided on the raising and lowering member as the frame member locking means. Since at least one of the upper side and the lower side of the holding section is flat, the frame member around the axis which is orthogonal to the frame member and extends horizontally as in the case of claim 3. Rotation is restricted. Therefore, the frame member in the raised position does not bend and rattle at the pin-connected portion.

【実施例】【Example】

以下、本考案の実施例を図面に基づいて説明する。まず、本考案の第１実施例のクーハンについて説明する。ここで、図１は、枠材１２を上昇位置に保持しているときのクーハン１の斜視図、図２は、枠材１２を下降位置に下ろしたときのクーハン１の側面図、図３と図４は、枠材１２とベッド２とを二つ折に折り畳んだときの側面図と正面図である。 Embodiments of the present invention will be described below with reference to the drawings. First, the Kuhan of the first embodiment of the present invention will be described. Here, FIG. 1 is a perspective view of the coohan 1 when the frame member 12 is held in the raised position, and FIG. 2 is a side view of the coohan 1 when the frame member 12 is lowered to the lowered position. FIG. 4 is a side view and a front view when the frame member 12 and the bed 2 are folded in two.

【００２０】第１実施例のクーハン１は、ベッド２と枠材１２と前側起倒部材２１、後側起倒部材２２とを有している。尚、このクーハン１も従来のクーハンと同様に、ベッド２を包んだ囲い布が枠材の全周に縫いつけられ、幌支持部材４１には幌布が縫いつけられて、ベッド２の周囲と上方が囲い布と幌布で覆われているが、図１〜図４の図面には、これら囲い布と幌布の図示は省略してある。The coohan 1 of the first embodiment has a bed 2, a frame member 12, a front-side tilting member 21, and a rear-side tilting member 22. As in the case of the conventional Kuhan, the surrounding cloth around the bed 2 is also sewn with the surrounding cloth enclosing the bed 2 around the entire circumference of the frame member and the hood supporting member 41 with the hood cloth. Although the upper part is covered with the wrapping cloth and the hood cloth, the illustration of the wrapping cloth and the hood cloth is omitted in the drawings of FIGS. 1 to 4.

【００２１】ベッド２は、図２に示すように前側ベッド３と後側ベッド４を互いに当接し、当接した部分の各々の下面に補強板５、５を貼着し、その補強板５、５に蝶番６を取着して、前側ベッド３と後側ベッド４とが二つ折自在に連結されている。前側ベッド３と後側ベッド４上に一枚のマットレス７を載置し、そのマットレス７と前側ベッド３と後側ベッド４の下面縁部までを包むようにシーツ８がかぶせてある。そして、シーツ８の全縁に一本のゴム帯が縫いつけてあって、そのゴム帯の弾力でマットレス７と前、後側ベッド３、４を一体に保持している。従って、ベッド２を二つ折にしても（図３の状態）、マットレス７が前、後ベッド３、４から外れない。この時には図３のようにゴム帯が伸びてシーツ８が引き出されて、マットレス７を保持している。尚、前側ベッド３と後側ベッド４とを同一形状にすると、二つ折にしたとき完全に重合するので実用上好ましい。In the bed 2, as shown in FIG. 2, the front bed 3 and the rear bed 4 are in contact with each other, and the reinforcing plates 5 and 5 are attached to the lower surfaces of the contacted portions. A hinge 6 is attached to 5, and the front bed 3 and the rear bed 4 are foldably connected to each other. A single mattress 7 is placed on the front bed 3 and the rear bed 4, and the sheets 8 are covered so as to wrap the mattress 7, the front bed 3 and the lower edge of the rear bed 4. A single rubber band is sewn on all edges of the sheet 8, and the elasticity of the rubber band holds the mattress 7 and the front and rear beds 3 and 4 integrally. Therefore, even if the bed 2 is folded in two (state of FIG. 3), the mattress 7 cannot be separated from the front and rear beds 3, 4. At this time, as shown in FIG. 3, the rubber band extends and the sheet 8 is pulled out to hold the mattress 7. If the front bed 3 and the rear bed 4 have the same shape, they are completely polymerized when folded in two, which is practically preferable.

【００２２】枠材１２は、ベッド２の外周を囲むように折曲形成したアルミパイプ製の前側枠材１３と後側枠材１４が、接手部材１５を介してピン１６、１６連結されて、二つ折自在になっている。前側枠材１３と後側枠材１４の先端には、それぞれ接手部材１５嵌入部分を平板状にした鋼管１７、１８を溶着して、枠材１２の軽量化と連結部の摩耗防止を図っている。接手部材１５は下方が開放したコ字状の断面形状で、その上壁の内壁面１５ａに図６のように鋼管１７、１８の上面が当接して、前側枠材１３と後側枠材１４の上昇位置（図１の位置）の傾斜角度が規制されている。鋼管１７、１８の先端面１７ａ、１８ａを接手部材１５の内壁面１５ａに当接させて、前側枠材１３と後側枠材１４を二つ折した時（図６の仮想線で図示した状態）の揺動角度（折り畳み角度）を規制している。第１実施例では、前側枠材１３の揺動角度は略１００°、後側枠材１４の揺動角度はは略９０° にして、枠材１２が上昇位置にある時、前側枠材１３が上向きに、後側枠材１４は略水平になるようにしている。The frame member 12 is formed by bending a front frame member 13 and a rear frame member 14 made of an aluminum pipe so as to be bent so as to surround the outer periphery of the bed 2 by connecting pins 16 and 16 via a joint member 15. It can be folded in two. The front end of the front frame member 13 and the rear end frame member 14 are welded to the steel pipes 17 and 18 each having a fitting member 15 fitted into a flat plate shape to reduce the weight of the frame member 12 and prevent wear of the connecting portion. ing. The joint member 15 has a U-shaped cross-section with an open bottom, and the inner wall surface 15a of the upper wall thereof abuts the upper surfaces of the steel pipes 17 and 18 as shown in FIG. The inclination angle of the raised position (position in FIG. 1) of the material 14 is regulated. When the front end surfaces 17a and 18a of the steel pipes 17 and 18 are brought into contact with the inner wall surface 15a of the joint member 15 and the front frame member 13 and the rear frame member 14 are folded in two (state shown by phantom lines in FIG. 6) ) Swing angle (folding angle) is regulated. In the first embodiment, the rocking angle of the front frame member 13 is approximately 100 °, and the rocking angle of the rear frame member 14 is approximately 90 °, and when the frame member 12 is in the raised position, the front frame member 13 is Is directed upward, and the rear frame member 14 is made substantially horizontal.

【００２３】後側起倒部材２２は、１本の丸棒を図５に示すように左右対称の湾曲ガイド部２３、２３と左右の軸受部２４、２４と起立保持部２５に折曲成形されており、湾曲ガイド部２３、２３は軸受部２４、２４の端部から湾曲して伸び出ている。前側起倒部材２１も同様に折曲成形されており、前側起倒部材２１の湾曲ガイド部２３の長さは後側起倒部材２２より長くなっている。前側起倒部材２１と後側起倒部材２２の軸受部２４が、それぞれ前側ベッド３と後側ベッド４の下面に取着した軸受２６、２７に軸支され、前側、後側起倒部材２１、２２、が前後方向に互いに対向して揺動するようになっている。As shown in FIG. 5, the rear erection member 22 is formed by bending one round bar into left and right symmetric curved guide portions 23, 23, left and right bearing portions 24, 24, and an upright holding portion 25. The curved guide portions 23, 23 are curved and extend from the ends of the bearing portions 24, 24. Similarly, the front upright member 21 is also bent, and the length of the bending guide portion 23 of the front upright member 21 is longer than that of the rear upright member 22. The bearing portions 24 of the front and rear raising members 21 and 22 are pivotally supported by bearings 26 and 27 attached to the lower surfaces of the front bed 3 and the rear bed 4, respectively. , 22 oscillate so as to face each other in the front-rear direction.

【００２４】前側、後側起倒部材２１、２２が起立した時（図１の状態の時）には、それぞれの起立保持部２５、２５が前側、後側ベッド３、４の下面に当接して、枠材１２を上昇位置に保持するようになっている。前側ベッド３の突合せ端面から軸受２６までの長さｍが後側ベッド４の突合せ端面から軸受２７までの長さｎより長くなっていて（図２参照）、ベッド２を二つ折りにしたとき、軸受２６、２７や前側、後側起倒部材２１、２２の起立保持部２５、２５が干渉しないようになっている。When the front and rear upright members 21, 22 are upright (in the state of FIG. 1), the upright holding portions 25, 25 are respectively attached to the lower surfaces of the front and rear beds 3, 4. It abuts and holds the frame member 12 in the raised position. When the length m from the butt end surface of the front bed 3 to the bearing 26 is longer than the length n from the butt end surface of the rear bed 4 to the bearing 27 (see FIG. 2), when the bed 2 is folded in two. The bearings 26 and 27 and the upright holding portions 25 and 25 of the front and rear upright members 21 and 22 do not interfere with each other.

【００２５】前側、後側起倒部材２１、２２の左右の湾曲ガイド部２３、２３は、前側、後側枠材１３、１４と、図７に示すように連結金具３０によって連結されている。この実施例の連結金具３０は、連結ボルト３１にワッシャー３２、円錐形バネ３３、ワッシャー３４を嵌め、その連結ボルト３１を２本の湾曲ガイド部２３、２３の間を通して前側枠材１３または後側枠材１４に挿着し、その先端にナット３５を螺着した構成になっている。従って、前側枠材１３、後側枠材１４を上下動すると、枠材１２は円錐形バネ３３の弾力で湾曲ガイド部２３に圧接して摺動し、任意の上下位置で停止すると、枠材１２はその位置に保持されている。The left and right curved guide portions 23, 23 of the front and rear up-and-down members 21, 22 are connected to the front and rear frame members 13, 14 by a connecting fitting 30 as shown in FIG. In the connecting fitting 30 of this embodiment, a washer 32, a conical spring 33, and a washer 34 are fitted to a connecting bolt 31, and the connecting bolt 31 is passed between the two curved guide portions 23 and 23, or the front frame member 13 or It is configured such that it is inserted into the rear frame member 14 and a nut 35 is screwed into the tip thereof. Therefore, when the front frame member 13 and the rear frame member 14 are moved up and down, the frame member 12 is pressed against the curved guide portion 23 by the elastic force of the conical spring 33 and slides. 12 is held in that position.

【００２６】図８は、前記実施例の前側、後側起倒部材２１、２２の湾曲ガイド部２３が１本の丸棒で成形されている場合の連結金具の例である。この連結金具３０Ａは、枠材５２に装着した連結ピン５３に起倒部材の湾曲ガイド５４を摺動自在に挿着し、その連結ピン５３に板ばね５５を介してナット５６を螺着した構成であり、このようにすると、枠材５２から外へ出る部分を連結ピン５３の頭部だけにすることができる。FIG. 8 shows an example of the connecting metal fitting in the case where the curved guide portions 23 of the front and rear raising and lowering members 21 and 22 of the above embodiment are formed by one round bar. This connecting fitting 30A has a structure in which a bending guide 54 of a tilting member is slidably attached to a connecting pin 53 mounted on a frame member 52, and a nut 56 is screwed to the connecting pin 53 via a leaf spring 55. By doing so, only the head of the connecting pin 53 can be exposed to the outside from the frame member 52.

【００２７】図１において、４１は幌布を支持する幌支持部材であり、左右のつまみ４２を調節して図示しない幌布を任意の覆い角度に調整するようになっていることは従来と同様である。４４はクーハン１の持ち運びに用いる吊り紐であり、この実施例は止め金具４５によって左右の枠材１２に着脱できるようになっている。吊り紐４４は前記連結金具３０と共に枠材１２に固着してもよいし、枠材１２に縫いつけてもよい。In FIG. 1, reference numeral 41 denotes a hood support member for supporting the hood cloth, and it is conventional that the hood cloth (not shown) is adjusted to an arbitrary covering angle by adjusting the left and right knobs 42. It is the same. Reference numeral 44 is a hanging string used for carrying the Kuhan 1, and in this embodiment, it can be attached to and detached from the left and right frame members 12 by a stopper fitting 45. The hanging string 44 may be fixed to the frame member 12 together with the connecting fitting 30, or may be sewn to the frame member 12.

【００２８】次に、この実施例のクーハン１の使用方法について説明する。図１の状態で使用していたクーハン１を畳む場合には、上昇位置の枠材１２の左右の接手部材１５を両手で押し下げると、左右前後の４個の連結金具３０が前側起倒部材２１と後側起倒部材２２のガイド部２３に沿って摺動しながら同時に下降する。それにともなって前側起倒部材２１は前に倒れ、後側起倒部材２２は後に倒れて行く。下降位置まで接手部材１５を押し下げると、略図２の状態になる。この時に、赤ん坊を片手で抱いている場合には、他方の手で接手部材１５を片方づつ押し下げればよい。Next, a method of using the coohan 1 of this embodiment will be described. When the Kuhan 1 used in the state shown in FIG. 1 is folded, when the left and right joint members 15 of the frame member 12 in the raised position are pushed down with both hands, the four left, right, front and rear connecting fittings 30 are brought to the front upright member. 21 and the rear raising / lowering member 22 slide simultaneously along the guide portion 23 and simultaneously descend. Along with that, the front-side tilting member 21 falls forward, and the rear-side tilting member 22 falls backward. When the joint member 15 is pushed down to the lowered position, the state shown in FIG. 2 is obtained. At this time, when holding the baby with one hand, the other hand may be used to push down the contact members 15 one by one.

【００２９】続いて、ベッド２を裏返しにしてから、前側枠材１３の前端部または後側枠材１４の後端部の何れか一方を手に持って二つ折にすると、前側、後側枠材１３、１４はピン１６、１６を支点にして図３のように折り畳まれる。この時、前側枠材１３と前側ベッド３が前側起倒部材２１で連結され、後側枠材１４と後側ベッド４が後側起倒部材２２で連結されているので、前側、後側枠材１３、１４の折り畳みにつれて前側、後側ベッド３、４も同時に折り畳まれる（図３に仮想線で図示したように同時に折り畳まれて行く）。Subsequently, after the bed 2 is turned inside out, if either the front end of the front frame member 13 or the rear end of the rear frame member 14 is held in the hand and folded in two, the front and rear frame members are folded. The members 13 and 14 are folded as shown in FIG. 3 with the pins 16 and 16 as fulcrums. At this time, the front frame member 13 and the front bed 3 are connected by the front raising / lowering member 21, and the rear frame member 14 and the rear bed 4 are connected by the rear raising / lowering member 22. As the frame members 13 and 14 are folded, the front and rear beds 3 and 4 are also folded at the same time (they are folded at the same time as shown by phantom lines in FIG. 3).

【００３０】従って、このクーハン１を折り畳む場合には、枠材１２を押し下げて二つ折にするだけであるから簡単迅速に行うことができる。赤ん坊を片手で抱いていても容易に折り畳むことができる。一方、折り畳まれているクーハン１を使用状態（図１の状態）に復帰させる場合には、持っていた前側枠材１３、後側枠材１４の一方の枠材を離して図２のように広げた後、赤ん坊をベッド２上に寝かせて、吊り紐４４を上方へ持ち上げるだけでよい。枠材１２の連結金具３０が前側、後側起倒部材２１、２２のガイド部２３を摺動して、枠材１２は上昇位置に復帰する。Therefore, when the Kuhan 1 is folded, since it is only necessary to push down the frame member 12 to make two folds, it is possible to easily and quickly perform the folding. You can easily fold a baby while holding it with one hand. On the other hand, when the folded Kuhan 1 is returned to the use state (state of FIG. 1), one of the front side frame member 13 and the rear side frame member 14 that have been held is released and the one shown in FIG. After unfolding, all that is required is to lay the baby on the bed 2 and lift the sling 44 upward. The connecting member 30 of the frame member 12 slides on the guide portions 23 of the front and rear raising and lowering members 21, 22 to return the frame member 12 to the raised position.

【００３１】この状態で赤ん坊を寝かせていて、例えば、おむつや肌着を交換するときには、後側枠材１４の後端部（図１の左端部）が床面に着くまで押し下げて、手前の枠材と囲い布を開放すると、おむつや肌着の交換作業が容易になる。以上詳述したように、第１実施例のクーハン１においては、前側ベッド３と後側ベッド４とを蝶着した二つ折自在のベッド２と、前側枠材１３と後側枠材１４とをピン１６、１６にて連結した二つ折自在の枠材１２とを備えている。よって、空のクーハン１を二つ折にすることができ、折り畳まれたクーハンはコンパクトになるので、携帯が容易になるという効果がある。When the baby is laid down in this state and, for example, when changing diapers or underwear, push down until the rear end (left end in FIG. 1) of the rear frame member 14 reaches the floor surface, and then press the front frame. Opening the material and wrapping cloth makes it easier to change diapers and underwear. As described above in detail, in the Kuhan 1 of the first embodiment, the foldable bed 2 in which the front bed 3 and the rear bed 4 are hinged, the front frame member 13 and the rear frame member 14 are provided. It is provided with a frame member 12 that can be folded in two and is connected by pins 16 and 16. Therefore, the empty Kuhan 1 can be folded in two, and the folded Kuhan becomes a compact, so that it is easy to carry.

【００３２】また、第１実施例によれば、前側、後側起倒部材２１、２２が湾曲ガイド部２３、２３を備えるとともに、湾曲ガイド部２３、２３と枠材１２を連結金具３０によって連結しているので、枠材１２を容易に上昇位置及び下降位置に移動させることができ、クーハン１を容易に畳んだり、組立てたりすることができるという効果がある。Further, according to the first embodiment, the front and rear raising members 21, 22 are provided with the curved guide portions 23, 23, and the curved guide portions 23, 23 and the frame member 12 are connected by the metal fitting 30. Since they are connected, the frame member 12 can be easily moved to the raised position and the lowered position, and the Kuhan 1 can be easily folded and assembled.

【００３３】次に、第２実施例のクーハンについて説明する。ここで、図９は、枠材１１２が上昇位置にあるクーハン１０１の側面図、図１０は同正面図、図１１は枠材１１２とベッド１０２とを二つ折に折り畳んだときの側面図である。尚、第２実施例のクーハン１０１において、第１実施例と同様な部分については、第１実施例に付した符号に１００を加えた符号を付し、特に第１実施例と変わっていない部分については説明を省略する。Next, the coohan of the second embodiment will be described. Here, FIG. 9 is a side view of the Kuhan 101 in which the frame member 112 is in a raised position, FIG. 10 is a front view of the same, and FIG. 11 is a side view of the frame member 112 and the bed 102 folded in two. is there. In addition, in the coohan 101 of the second embodiment, the same parts as those of the first embodiment are denoted by the reference numerals added to the reference numerals of the first embodiment plus 100, and there is no particular difference from the first embodiment. The description of the minutes will be omitted.

【００３４】第２実施例のクーハン１０１も、第１実施例と同様に２つ折に折畳めるものであるが、起倒部材１２１の先端に設けられた扁平状の嵌合部１６３を、枠材１１２に取り付けられた金属板１５１の長孔１５３に係止させて枠材１１２を上昇位置に保つ点において、第１実施例と異なっている。つまり、クーハン１０１は、枠材係止手段として、長孔１５３と、起倒部材１２１の先端に設けられた扁平状の嵌合部１６３とを備えるものである。尚、第２実施例のクーハン１０１も、第１実施例と同様にベッド１０２を包んだ囲い布が枠材１１２の全周に縫いつけられ、枠材１１２に取り付けられた幌支持部材（図示略）には幌布が縫いつけられており、ベッド１０２の周囲と上方が囲い布と幌布で覆われているが、図９〜図１１の図面には、これら囲い布と幌布の図示は省略してある。The coohan 101 of the second embodiment is also capable of being folded in two in the same manner as in the first embodiment, but the flat-shaped fitting portion 163 provided at the tip of the raising and lowering member 121 has a frame member. This is different from the first embodiment in that the frame member 112 is held in the elevated position by being locked in the elongated hole 153 of the metal plate 151 attached to 112. That is, the Kuhan 101 includes the elongated hole 153 and the flat fitting portion 163 provided at the tip of the tilting member 121 as the frame member locking means. In the coohan 101 of the second embodiment, as in the case of the first embodiment, the surrounding cloth of the bed 102 is sewn on the entire circumference of the frame member 112, and the hood support member (not shown) attached to the frame member 112. ) Is sewn with hood cloth, and the perimeter and upper part of the bed 102 are covered with wrapping cloth and hood cloth. However, the drawings of these wrapping cloth and hood cloth are omitted in the drawings of FIGS. 9 to 11. I am doing it.

【００３５】ベッド１０２は、図９に示すように、第１実施例と同様に前側ベッド１０３と後側ベッド１０４が二つ折自在に連結されたものであり、前側、後側ベッド１０３、１０４には、各々図１２に示すような起倒部材１２１が左右対称に取り付けられているこの起倒部材１２１は、図１２（Ａ）の斜視図に示すように、１本の金属製の丸棒を折曲げ成形したものであり、上側に延びる左右対称の垂直部１２３、１２３と、左右の軸受部１２４、１２４と、起立保持部１２５とに折曲成形されている。そして、両垂直部１２３、１２３の先端側（上側）には、外側に略Ｕ字状に膨らんだ湾曲部１６１が形成され、この湾曲部１６１に連続して、枠材１１２の長孔１５３に嵌合する扁平状の嵌合部１６３が内側略水平方向に突設されている。この嵌合部１６３は、図１２（Ｂ）（嵌合部１６３を示す平面図）に示すように、丸棒の先端部分を略Ｕ字状に折曲げて形成した部分であり、その円みを帯びた曲折部分が枠材１１２の内側方向（矢印Ｃ方向）に向いている。また、嵌合部１６３の端部１６３ａは、約９０゜折り曲げられ、湾曲部１６１に向けて延出している。As shown in FIG. 9, the bed 102 is a bed in which a front bed 103 and a rear bed 104 are foldably connected to each other, as in the first embodiment, and the front and rear beds 103, 104 are provided. Each of the up and down members 121 as shown in FIG. 12 is symmetrically attached to the up and down member 121. As shown in the perspective view of FIG. Is formed by bending, and the left and right symmetrical vertical portions 123 and 123 extending upward, the left and right bearing portions 124 and 124, and the upright holding portion 125 are formed by bending. A curved portion 161 that bulges out in a substantially U-shape is formed on the tip side (upper side) of both vertical portions 123, 123. The curved portion 161 is continuous with the curved portion 161 and is formed in the long hole 153 of the frame member 112. A flat-shaped fitting portion 163 to be fitted is provided so as to project inward in a substantially horizontal direction. As shown in FIG. 12 (B) (plan view showing the fitting portion 163), the fitting portion 163 is a portion formed by bending the tip end portion of the round bar into a substantially U shape, and its roundness. The bent portion with a curve is directed inward of the frame member 112 (direction of arrow C). Further, the end portion 163a of the fitting portion 163 is bent about 90 ° and extends toward the curved portion 161.

【００３６】そして、図９に示すように、前側および後側ベッド１０３、１０４に揺動可能に軸支された起倒部材１２１、１２１は、起倒部材１２１が垂直に起立した状態においては、起立保持部１２５、１２５が前側、後側ベッド１０３、１０４の下面に当接して、枠材１１２を上昇位置に保持するようになっている。また、枠材１１２の長孔１５３と嵌合部１６３の係止を解除すれば、２つの起倒部材１２１、１２１を各々２点鎖線で示す位置に倒すことができる。また、前側ベッド３の突合せ端面から軸受１２６までの長さｍ´が後側ベッド１０４の突合せ端面から軸受１２７までの長さｎ´より短くなっている。Then, as shown in FIG. 9, the raising and lowering members 121 and 121 pivotally supported by the front and rear beds 103 and 104 are as follows. The upright holding portions 125, 125 are in contact with the lower surfaces of the front and rear beds 103, 104 to hold the frame member 112 at the raised position. Further, if the locking of the elongated hole 153 of the frame member 112 and the fitting portion 163 is released, the two raising and lowering members 121, 121 can be brought down to the positions shown by the two-dot chain line. The length m ′ from the abutting end surface of the front bed 3 to the bearing 126 is shorter than the length n ′ from the abutting end surface of the rear bed 104 to the bearing 127.

【００３７】尚、図１０に示すように、起倒部材１２１の両垂直部１２３、１２３は、嵌合部１６３が長孔１５３に係止されていない状態においては、２点鎖線で示すように枠材１１２の内側に１５度〜２０度ほど傾いているが、嵌合部１６３が長孔１５３に係止された状態においては、両垂直部１２３、１２３は（水平面に対して）ほぼ垂直となる。As shown in FIG. 10, the two vertical portions 123, 123 of the tilting member 121 are indicated by a two-dot chain line when the fitting portion 163 is not locked in the elongated hole 153. Although inclined by 15 to 20 degrees inside the frame member 112, when the fitting portion 163 is locked in the long hole 153, both vertical portions 123, 123 are substantially vertical (with respect to the horizontal plane). Becomes

【００３８】一方、枠材１１２の前側および後側枠材１１３、１１４には、上述の起倒部材１２１の嵌合部１６３に対応する位置に、長孔１５３が穿設された金属板１５１が固定されている。この金属板１５１は、図１３（Ａ）および（Ｂ）（図１３（Ａ）におけるＡ−Ａ断面図）に示すように、アルミパイプよりなる前側枠材１１３（または後側枠材１１４）の一部分を扁平状に押し潰して形成された取付部１６７に取り付けられている。即ち、図１３（Ｂ）に示すように、金属板１５１の上側には略Ｕ字状の折曲部１６９が形成されており、この折曲部１６９の内側に取付部１６７をはめ込み、折曲部１６９を取付部１７３に対して溶着することによって、金属板１５１を前側および後側枠材１１３、１１４に固定している。On the other hand, the front and rear frame members 113 and 114 of the frame member 112 are provided with metal plates 151 each having a long hole 153 at a position corresponding to the fitting portion 163 of the raising and lowering member 121. It is fixed. As shown in FIGS. 13 (A) and 13 (B) (A-A cross-sectional view in FIG. 13 (A)), this metal plate 151 has a front frame member 113 (or a rear frame member 114) made of an aluminum pipe. Is attached to a mounting portion 167 formed by crushing a part of the flat shape. That is, as shown in FIG. 13 (B), a substantially U-shaped bent portion 169 is formed on the upper side of the metal plate 151, and the mounting portion 167 is fitted inside the bent portion 169 and bent. The metal plate 151 is fixed to the front and rear frame members 113 and 114 by welding the portion 169 to the mounting portion 173.

【００３９】そして、金属板１５１に穿設されている長孔１５３は、前側および後側枠材１１３、１１４の長手方向に沿って延びており、その上下幅は、起倒部材１２１を形成する丸棒の直径にほぼ等しい。一方、その横幅は、図１２（Ｂ）に示す起倒部材１２１の嵌合部１６３の横幅Ｗに等しい。よって、図１３（Ｃ）の斜視図にに示すように、嵌合部１６３を長孔１５３に挿入すると、嵌合部１６３の側部１６３ａ、１６３ｂが長孔の端部１５３ａ，１５３ｂに当接して、嵌合部１６３が長孔１５３に確実に係止される。これにより、枠材１１２と２つの起倒部材１２１、１２１とが連結され、枠材１１２が上昇位置に保たれる。そして、このように長孔１５３に扁平状の嵌合部１６３を嵌合させることにより、この嵌合部分において、図１２および１３に１点鎖線で示す軸Ｘ（前側または後側枠材１１３、１１４に対して直交し且つ水平方向に延びる軸）を中心とした前側および後側枠材１１３、１１４の回転が規制される。尚、図１０に示すように嵌合部１６３が長孔１５３に係止された状態においては、起倒部材１２１の垂直部１２３、１２３が弾性変形によって内側に傾こうとするので、嵌合部１６３は長孔１５３に対して外側から押し付けられて確実に係止される。The elongated hole 153 formed in the metal plate 151 extends along the longitudinal direction of the front and rear frame members 113 and 114, and the vertical width thereof forms the upright member 121. It is almost equal to the diameter of the round bar. On the other hand, its lateral width is equal to the lateral width W of the fitting portion 163 of the raising / lowering member 121 shown in FIG. 12 (B). Therefore, as shown in the perspective view of FIG. 13C, when the fitting portion 163 is inserted into the elongated hole 153, the side portions 163a and 163b of the fitting portion 163 contact the end portions 153a and 153b of the elongated hole. In contact with each other, the fitting portion 163 is securely locked in the long hole 153. As a result, the frame member 112 is connected to the two erecting members 121 and 121, and the frame member 112 is kept in the raised position. By fitting the flat fitting portion 163 into the elongated hole 153 in this manner, the axis X (front or rear frame member) indicated by the one-dot chain line in FIGS. The rotation of the front and rear frame members 113 and 114 around an axis that is orthogonal to 113 and 114 and extends in the horizontal direction is restricted. As shown in FIG. 10, when the fitting portion 163 is locked in the elongated hole 153, the vertical portions 123 and 123 of the tilting member 121 tend to incline inward due to elastic deformation. The portion 163 is pressed against the elongated hole 153 from the outside and securely locked.

【００４０】次に、第２実施例のクーハン１０１の使用方法について説明する。使用していた（即ち枠材１１２が上昇位置にある）クーハン１を畳む場合には、まず、図１０に示すように、前側ベッド１０３の起倒部材１２１の垂直部１２３、１２３を手で持って外側（矢印ＡおよびＡ´方向）に押し広げ、嵌合部１６３と長孔１５３の係止を外す。すると、図１０に２点鎖線で示すように、起倒部材１２１の垂直部１２３、１２３は弾性変形によって内側に傾く。また、後側ベッド１０４の起倒部材１２１についても、同様に嵌合部１６３と長孔１５３の係止を外す。尚、上述のように、ベッド１０２を包んだ囲い布（図示略）が枠材１１２の全周に縫いつけられ、ベッド１０２と枠材１１２は囲い布によってつながっているので、枠材１１２と２つの起倒部材１２１、１２１の接続を外しても、直ちに枠材１１２が下降位置まで落ち込んでしまうことはない。Next, a method of using the coohan 101 of the second embodiment will be described. When the Kuhan 1 that has been used (that is, the frame member 112 is in the raised position) is folded, first, as shown in FIG. 10, the vertical portions 123 and 123 of the raising and lowering member 121 of the front bed 103 are manually touched. Hold it and push it outward (in the directions of arrows A and A ') to unlock the fitting portion 163 and the long hole 153. Then, as shown by the chain double-dashed line in FIG. 10, the vertical portions 123 of the upright member 121 are inwardly inclined by elastic deformation. Also, with respect to the raising / lowering member 121 of the rear bed 104, the engagement between the fitting portion 163 and the long hole 153 is similarly removed. As described above, the wrapping cloth (not shown) that surrounds the bed 102 is sewn around the entire circumference of the frame material 112, and the bed 102 and the frame material 112 are connected by the wrapping cloth, so Even if the two upright members 121, 121 are disconnected, the frame member 112 does not immediately fall to the lowered position.

【００４１】次に、図９に示すように、両起倒部材１２１、１２１を２点鎖線で示す位置まで倒し、更に囲い布を折り畳みながら、枠材１１２を２点鎖線で示すように押し下げ、最終的には、第１実施例と同様に、枠材１１２をベッド１０２の周囲を囲む下降位置まで下ろす。これにより、クーハン１０１は偏平な状態となる。Next, as shown in FIG. 9, both the up-and-down members 121, 121 are tilted to the position shown by the chain double-dashed line, and the frame member 112 is pushed as shown by the chain double-dashed line while folding the surrounding cloth. Finally, as in the first embodiment, the frame member 112 is finally lowered to the lowered position that surrounds the periphery of the bed 102. As a result, the Kuhan 101 becomes flat.

【００４２】そして、第１実施例と同様にベッド１０２を裏返しにして二つ折にすれば、クーハン１０１は図１１のように折り畳まれる。尚、上述のように、ベッド１０２と枠材１１２は囲い布によってつながれているので、前側枠材１１３の前端部または後側枠材１１４の後端部の何れか一方を手に持って二つ折にすれば、前側、後側枠材１１３、１１４の折り畳みにつれて前側、後側ベッド１０３、１０４も同時に折り畳まれる。Then, if the bed 102 is turned upside down and folded in two as in the first embodiment, the couhan 101 is folded as shown in FIG. As described above, since the bed 102 and the frame member 112 are connected by the surrounding cloth, hold one of the front end portion of the front frame member 113 or the rear end portion of the rear frame member 114 in your hand. If it is folded in two, the front and rear beds 103 and 104 are simultaneously folded as the front and rear frame members 113 and 114 are folded.

【００４３】一方、折り畳まれているクーハン１を使用状態（図９の状態）に復帰させる場合は、上述の折り畳みと逆の手順で行えばよい。即ち、まず二つ折にされているベッド１０２および枠材１１２を広げた後、枠材１１２を上昇位置まで持ち上げ、起倒部材１２１、１２１を起立させる。そして、起倒部材１２１の垂直部１２３、１２３を手で外側に押し広げて、嵌合部１６３を長孔１５３に挿入・係止させれば、枠材１１２が上昇位置に保たれる。On the other hand, when the folded Kuhan 1 is returned to the use state (state of FIG. 9), the procedure reverse to the above-mentioned folding may be performed. That is, first, the bed 102 and the frame member 112, which are folded in two, are unfolded, and then the frame member 112 is lifted to the raised position to erect the upright members 121, 121. Then, if the vertical portions 123 and 123 of the tilting member 121 are pushed outward by hand and the fitting portion 163 is inserted and locked in the long hole 153, the frame member 112 is kept at the raised position.

【００４４】以上詳述したように、第２実施例のクーハン１０１においても、第１実施例と同様に二つ折にすることができるので、空のクーハンをコンパクトにすることができ、携帯が容易になるという効果がある。そして、特に第２実施例においては、起倒部材１２１の扁平状の嵌合部１６３を長孔１５３に嵌合・係止させているので、上昇位置にある枠材１１２が、ピン１１６、１１６によって連結された部分（前側および後側枠材１１３、１１４の連結部分）で折れ曲がることがなく、枠材１１２ががたつかないという効果がある。つまり、例えば図９に示すように、前側枠材１１３（または後側枠材１１４）の端部を下側（矢印Ｂ方向）に押さえたとしても、嵌合部１６３が長孔１５３に係止されている部分において、前側枠材１１３（または後側枠材１１４）の回転（軸Ｘを中心とする回転）が規制されているので、上昇位置にある枠材１１２が、ピン連結された部分で折れ曲がってがたつくことがない。よって、クーハン１０１を安全に使用することができる。また、特に第２実施例においては、扁平状の嵌合部１６３および長孔１５３という簡素な構成によって、枠材１１２のがたつきを確実に防止することができるという効果がある。As described in detail above, also in the coohan 101 of the second embodiment, since it can be folded in two as in the first embodiment, an empty coohan can be made compact and easy to carry. Has the effect of becoming. In particular, in the second embodiment, the flat fitting portion 163 of the tilting member 121 is fitted and locked in the elongated hole 153, so that the frame member 112 in the raised position has the pins 116, 116. There is an effect that the frame member 112 does not rattle because it is not bent at the portion connected (the connecting portion of the front and rear frame members 113 and 114). That is, for example, as shown in FIG. 9, even if the end portion of the front frame member 113 (or the rear frame member 114) is pressed downward (direction of arrow B), the fitting portion 163 is locked in the long hole 153. Since rotation of the front frame member 113 (or the rear frame member 114) (rotation about the axis X) is restricted in the portion where the frame member 112 is in the raised position, the frame member 112 in the raised position is pin-connected. There are no bends and rattles in the parts. Therefore, the Kuhan 101 can be used safely. Further, particularly in the second embodiment, the simple structure of the flat fitting portion 163 and the elongated hole 153 has an effect that the rattling of the frame member 112 can be reliably prevented.

【００４５】また、第２実施例によれば、起倒部材１２１を形成する丸棒の先端部を略Ｕ字状に折曲げて扁平状の嵌合部１６３を形成しているので、製作が容易でしかも材料費がかからず、製造コストを低く抑えることができるという効果がある。更に、本実施例においては、図１２（Ｂ）に示すように、嵌合部１６３の略Ｕ字状の曲折げ部分が枠材１１２の内側（矢印Ｃ方向：即ちクーハン１０１の内側方向）に向いている。よって、クーハン１０１の内側に突出する嵌合部１６３の先端部分によって、クーハン１０１の中の赤ん坊が傷つけられることがなく、安全性が高いという利点がある。Further, according to the second embodiment, since the tip end portion of the round bar forming the raising and lowering member 121 is bent into a substantially U shape to form the flat fitting portion 163, the manufacturing is easy. It is easy and requires no material cost, and the manufacturing cost can be kept low. Further, in this embodiment, as shown in FIG. 12 (B), the bent portion of the fitting portion 163 having a substantially U shape is located inside the frame member 112 (direction of arrow C: inward direction of Coohan 101). It is facing. Therefore, there is an advantage that the baby inside the coohan 101 is not damaged by the tip part of the fitting part 163 protruding inside the coohan 101 and the safety is high.

【００４６】以上、本考案の実施例を説明したが、本考案は上記実施例に限定されるものではなく、種々の態様で実施することのできるものである。例えば、図１６に示す従来のクーハンにおいても、枠材を前側枠材と後側枠材にして上記第１および第２実施例の接手部材を用いてピン連結し、ベッドを前側ベッドと後側ベッドにして蝶番で連結して上記実施例のように二つ折自在にしても良い。Although the embodiments of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments and can be implemented in various modes. For example, in the conventional Coohan shown in FIG. 16 as well, the frame members are the front frame member and the rear frame member, and the pins are connected using the joint members of the first and second embodiments, and the beds are connected to the front and rear beds. It may be made into a bed and connected by hinges so that it can be folded in two as in the above embodiment.

【００４７】また、上記第２実施例においては、枠材係止手段として、枠材１１２に設けられた長孔１５３と、起倒部材１２１に設けられた嵌合部１６３とを備えているが、これとは逆に、枠材１１２側に偏平状の嵌合部を突設し、起倒部材１２１側に長孔を設けても良い。また、上記第２実施例においては、長孔１５３は前側および後側枠材１１３、１１４の長手方向に沿って延びているが、長孔１５３が長手方向に対して斜め方向あるいは直角方向に延びていても、上記第２実施例と同様に、枠材のがたつきを抑えることができる。また、偏平状の嵌合部として、長孔に嵌合される板状の部材を起倒部材に固定してもよい。In addition, in the second embodiment, as the frame member locking means, the elongated hole 153 provided in the frame member 112 and the fitting portion 163 provided in the raising / lowering member 121 are provided. However, conversely, a flat fitting portion may be provided on the frame member 112 side, and a long hole may be provided on the raising / lowering member 121 side. Further, in the second embodiment, the elongated hole 153 extends along the longitudinal direction of the front and rear frame members 113 and 114, but the elongated hole 153 is oblique or perpendicular to the longitudinal direction. Even if the frame member extends to the end, the rattling of the frame member can be suppressed as in the second embodiment. Further, as the flat fitting portion, a plate-shaped member fitted into the long hole may be fixed to the tilting member.

【００４８】また、枠材係止手段として、上側部と下側部とで枠材を挾持する挾持部を起倒部材に設けることもできる。即ち、例えば図１４に示すように、棒材よりなる起倒部材１７１の先端部を第２実施例と同様に折曲げ、外側に膨らむ湾曲部１７３の下側部１７３ａと、略Ｕ字状の扁平部１７５の間の間隔Ｈを前側枠材１７７（または後側枠材１７８）の直径と同じ程度に狭めて挾持部１７２を形成し、この挾持部１７２に前側枠材１７７（または後側枠材１７８）を挟むようにしてもよい。この場合、図１４（ｂ）に示すように、前側または後側枠材１７７、１７８は、略Ｕ字状の扁平部１７５（即ち扁平状の上側部）と、湾曲部１７３の下側部１７３ａとで上下から挟まれる。よって、上記第２実施例の場合と同様に、挾持部１７２に挟まれた部分において、前側枠材１７７（または後側枠材１７８）に直交し且つ水平方向に延びる軸を中心とした前側枠材１７７（または後側枠材１７８）の回転が規制されるので、上昇位置にある枠材がピン連結された部分で折れ曲がってがたつくことがなくなる。なお、下側部１７３ａを偏平状に折り曲げ形成しても、同様な効果が得られる。Further, as the frame member locking means, a holding portion for holding the frame member between the upper side portion and the lower side portion may be provided on the tilting member. That is, for example, as shown in FIG. 14, the tip end portion of the erecting member 171 made of a bar is bent in the same manner as in the second embodiment, and the lower portion 173a of the curved portion 173 that bulges outward and the substantially U-shape. The spacing H between the flat portions 175 is narrowed to the same extent as the diameter of the front frame member 177 (or the rear frame member 178) to form the holding portion 172, and the holding portion 172 includes the front frame member 177 (or the rear frame member 177). The frame member 178) may be sandwiched. In this case, as shown in FIG. 14 (b), the front or rear frame members 177, 178 are composed of a substantially U-shaped flat portion 175 (that is, a flat upper portion) and a lower portion of the curved portion 173. It is sandwiched with 173a from above and below. Therefore, as in the case of the second embodiment described above, in the portion sandwiched by the holding portions 172, the axis perpendicular to the front frame member 177 (or the rear frame member 178) and extending in the horizontal direction is the center. Since the rotation of the front side frame member 177 (or the rear side frame member 178) is restricted, the frame member in the raised position does not bend and rattle at the pin-connected portion. Even when the lower portion 173a is formed into a flat shape by bending, the same effect can be obtained.

【００４９】また、枠材係止手段として挾持部を設ける場合、図１５に示すように、起倒部材１８１の先端に、断面略Ｕ字状の挾持部１８３を設け、この挾持部１８３に前側枠材１８５（または後側枠材１８６）をはめ込んで、枠材を上昇位置に保持するように構成してもよい。この場合、挾持部１８３の偏平状の上側部１８３ａと、同じく偏平状の下側部１８３ｂとで前側枠材１８５（または後側枠材１８６）が挾持されるので、上記実施例と同様に、上昇位置にある枠材がピン連結された部分で折れ曲がってがたつくことがなくなる。Further, when a holding portion is provided as the frame member locking means, as shown in FIG. 15, a holding portion 183 having a substantially U-shaped cross section is provided at the tip of the raising and lowering member 181 and the holding portion 183 is provided. The front frame member 185 (or the rear frame member 186) may be fitted so as to hold the frame member in the raised position. In this case, since the front side frame member 185 (or the rear side frame member 186) is held by the flat upper part 183a of the holding part 183 and the flat lower part 183b of the holding part 183, the same manner as in the above embodiment is performed. There is no bending and rattling at the part where the frame material in the raised position is pin-connected.

【００５０】なお、図１４および図１５に例示するように挾持部を設ける場合、枠材を挟む上側部と下側部の少なくとも一方を偏平状とすれば、枠材の回転が規制されるので、上昇位置にある枠材がピン連結された部分で折れ曲がってがたつくことがなくなる。In addition, in the case of providing a holding portion as illustrated in FIGS. 14 and 15, if at least one of the upper side and the lower side sandwiching the frame member is made flat, rotation of the frame member is restricted. Thus, the frame material in the raised position is not bent and rattling at the pin-connected portion.
