この考案は、一般にクーハンと呼ばれている赤ん坊専用ベッドに関するもので ある。 This invention relates to a baby-only bed, which is generally called Kuhan.
【0002】[0002]
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P 8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P 9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]
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.
【0019】[0019]
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1 5a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.

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1 2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3 3、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、2 3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3 5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2 3、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1 12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11 2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10 3、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、12 3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1 53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11 3(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1 67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1 13、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1 63a、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12 1、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、12 3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12 3、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16 3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1 12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12 3、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1 77(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17 5(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.
