Description

本発明は、プレイヤード（プレイペン）の折り畳み構造に関する。   The present invention relates to a folded structure of a playard (play pen).

従来、乳幼児が遊ぶ保護空間を提供するものとして、プレイヤード（プレイペン）が周知である。プレイヤードは、乳幼児が遊ぶ領域を区画する枠組であり、一般的に骨組構造体と、この骨組構造体を包囲する縫製布を備える。このようなものとして例えば特開２００８−１５４７５２（特許文献１）のプレイヤードは、４本の縦枠（柱）と、これら縦枠の上部に配置された４本の上横枠と、これら縦枠の下部に配置された４本の下横枠と、これら下横枠の上に載置された底板と、４本の縦枠の四方に張り渡されたフレームカバーとを有し、四方の側面および底面が閉鎖される。このことにより、プレイヤードの内部に収容された乳幼児が不用意に外部に出ることがないというものである。   2. Description of the Related Art Conventionally, playards (play pens) are well known as providing a protective space for infants to play. The playard is a frame that divides a region where an infant plays, and generally includes a frame structure and a sewing cloth that surrounds the frame structure. As such, for example, the playard disclosed in Japanese Patent Application Laid-Open No. 2008-154752 (Patent Document 1) includes four vertical frames (columns), four upper horizontal frames arranged above the vertical frames, and these vertical frames. 4 lower horizontal frames arranged at the lower part of the frame, a bottom plate placed on these lower horizontal frames, and a frame cover stretched in all directions of the 4 vertical frames. The side and bottom are closed. As a result, the infant accommodated inside the playard does not inadvertently go outside.

またプレイヤードは、持ち運びに資するよう軽量化され、不使用時にはコンパクトに折り畳まれるのが常套であり、特許文献１のフレームのうち水平に延びる上横枠（横材）が、両端側でそれぞれ延びるパイプ部材と、中央部に配置されて両端側のパイプ部材と回動可能に連結する第２折り畳み部で構成される。そして、展開状態で一端側のパイプ部材、第２折り畳み部、他端側のパイプ部材が一直線に延びる。また折り畳み状態でパイプ部材が第２折り畳み部に対して９０度となるよう回動し、これにより両端側のパイプ部材が互いに近づいて平行に揃う。かくして上横枠（横材）は、２箇所のピボット（回動連結点）を有し、使用状態で一直線に延び、折り畳みの際にはコ字状に変形する。   In addition, the playard is reduced in weight so as to contribute to carrying, and is normally folded compactly when not in use, and an upper horizontal frame (horizontal member) extending horizontally in the frame of Patent Document 1 extends on both ends. It comprises a pipe member and a second folding part that is disposed at the center and is rotatably connected to the pipe members on both ends. And the pipe member of the one end side, the 2nd folding part, and the pipe member of the other end side extend in a straight line in the unfolded state. Further, in the folded state, the pipe member is rotated so as to be 90 degrees with respect to the second folded portion, whereby the pipe members on both end sides approach each other and are aligned in parallel. Thus, the upper horizontal frame (transverse member) has two pivots (rotation connection points), extends in a straight line in use, and deforms into a U-shape when folded.

特開２００８−１５４７５２号公報 段落番号００５１ 図９Japanese Patent Laid-Open No. 2008-154752 Paragraph No. 0051 FIG.

しかし、特許文献１のプレイヤードにあっては、以下に説明するような問題を生ずる。つまりパイプ部材が第２折り畳み部に対して単にピボットで回動可能にされているにすぎず、回動を規制するロック手段を有しない。このため、使用状態および折り畳み状態の両方で不安定である。   However, the playerd of Patent Document 1 has the following problems. In other words, the pipe member is merely pivotable with respect to the second folding part, and does not have a locking means for restricting the pivoting. For this reason, it is unstable in both the use state and the folded state.

そこで、一端側のパイプ部材と第２折り畳み部を回動不能にロックする一方側のロック機構、および他端側のパイプ部材と第２折り畳み部を回動不能にロックする他方側のロック機構を設けることが考えられる。しかしながら、折り畳みの際、これらのロックをすべて解除したにもかかわらず解除が不完全となってしまう懸念がある。この場合、一方のロック機構が解除されず、折り畳み操作がやりづらい。特に、プレイヤードを折り畳む際には複数本の上横枠（横材）を折り畳まなければならないことから、多くのロック機構をすべて確実に解除することは煩雑である。   Therefore, a locking mechanism on one side that locks the pipe member on the one end side and the second folding part so as not to rotate, and a locking mechanism on the other side that locks the pipe member on the other end side and the second folding part so as not to rotate. It is conceivable to provide it. However, at the time of folding, there is a concern that the release may be incomplete despite all these locks being released. In this case, one of the lock mechanisms is not released, and the folding operation is difficult. In particular, when folding the playard, it is necessary to fold a plurality of upper horizontal frames (cross members), so it is troublesome to reliably release all the locking mechanisms.

本発明は、上述の実情に鑑み、折り畳み操作を容易に行うことができるプレイヤードを提供することを目的とする。   In view of the above circumstances, an object of the present invention is to provide a playable that can be easily folded.

この目的のため本発明によるプレイヤードは、複数の柱材、および柱材を互いに連結する複数の横材を有し、乳幼児を収容する空間の周囲を取り囲むように形成された折り畳み可能なフレーム構造体を備える。そして横材のうち少なくとも一部は、中程で折れ変形可能であり、長手方向一方部材と、長手方向他方部材と、長手方向中央部にあってこれら長手方向一方部材および長手方向他方部材と回動可能に連結する中央連結部材と、長手方向一方部材と中央連結部材を回動不能にする一方ロック機構と、長手方向他方部材と中央連結部材を回動不能にする他方ロック機構と、これら双方のロック機構を同時に解除して双方のロック解除を保持するロック動作機構を有する。   For this purpose, the playard according to the present invention has a foldable frame structure that includes a plurality of pillar members and a plurality of cross members that connect the pillar members to each other, and is formed so as to surround a space for accommodating an infant. Prepare the body. At least a part of the cross member can be bent and deformed in the middle, and is provided with one member in the longitudinal direction, the other member in the longitudinal direction, and the one member in the longitudinal direction and the other member in the longitudinal direction. A central coupling member that is movably coupled, a first locking mechanism that disables rotation of the one longitudinal member and the central coupling member, a second locking mechanism that disables rotation of the other longitudinal member and the central coupling member, and both A lock operation mechanism that simultaneously releases the lock mechanism and holds both lock releases.

かかる本発明によれば、双方のロック機構を同時に解除して双方のロック解除を保持するロック動作機構を有することから、乳幼児の保護者がロック動作機構を解除操作すると、一方ロック機構も他方ロック機構も確実にロック解除される。これにより、折り畳み操作を容易に行うことができる。なお中程で折れ変形可能とは、横材の長手方向中央部を含み、長手方向両端部を除いた長手方向途中の箇所で、折れ変形可能であると理解されたい。   According to the present invention, since the lock operation mechanism that releases both the lock mechanisms at the same time and holds both the lock releases is provided, when the guardian of the infant releases the lock operation mechanism, the one lock mechanism is also locked to the other. The mechanism is also unlocked reliably. Thereby, folding operation can be performed easily. It should be understood that being able to be bent and deformed in the middle means that it can be bent and deformed at a position in the middle of the longitudinal direction excluding both ends in the longitudinal direction, including the central portion in the longitudinal direction of the cross member.

１個の中央連結部材につき双方のロック解除を保持するロック動作機構の構造は双方のロック機構を同時に解除するものであれば特に限定されず、双方のロック機構と機械的にリンクする機構であっても、電動式であってもよい。本発明は一実施形態に限定されるものではないが、一方ロック機構は、中央連結部材に支持されて長手方向一方部材の回動を不能にするロック位置および長手方向一方部材の回動を許容するフリー位置に選択的にされる一方ロック部材を含む。他方ロック機構は、中央連結部材に支持されて長手方向他方部材の回動を不能にするロック位置および長手方向他方部材の回動を許容するフリー位置に選択的にされる他方ロック部材を含む。ロック動作機構は、一方ロック部材および他方ロック部材を同時にロック位置からフリー位置にする共通の操作子を含む。かかる実施形態によれば、乳幼児の保護者が共通する１個の操作子を操作することにより一方側ロック機構も他方側ロック機構も確実にロック解除される。したがってロック動作機構を好適に実現することができる。なお操作子はボタンであってもレバーであってもよく、特に限定されない。   The structure of the lock operation mechanism that holds both lock releases per one central connecting member is not particularly limited as long as both lock mechanisms are released simultaneously, and is a mechanism that mechanically links both lock mechanisms. Alternatively, it may be electric. Although the present invention is not limited to one embodiment, the one-side lock mechanism is supported by the central connecting member and allows the one-direction member in the longitudinal direction and the lock position to be prevented from rotating. Including a locking member that is selectively placed in a free position. The other lock mechanism includes a lock position that is supported by the central connecting member and disables rotation of the other member in the longitudinal direction, and a lock member that is selectively set to a free position that allows rotation of the other member in the longitudinal direction. The lock operation mechanism includes a common operation element that simultaneously moves the one lock member and the other lock member from the lock position to the free position. According to such an embodiment, the one-side locking mechanism and the other-side locking mechanism can be reliably unlocked by operating one common operating element by a guardian of the infant. Therefore, the lock operation mechanism can be preferably realized. The operation element may be a button or a lever, and is not particularly limited.

操作子は、原位置から操作位置に操作されることにより一方ロック部材および他方ロック部材を同時に解除するものであればよく、ロック部材を作動させる際の動作については特に限定されない。操作子は、手動で操作位置から原位置に戻されるものであってもよいが、好ましくは自動で操作位置から原位置に戻される。例えば、操作子は、原位置から操作位置に操作されることにより一方ロック部材および他方ロック部材をロック位置からフリー位置に動作させ、ロック動作機構は、操作子を原位置に復帰させるリターンスプリングをさらに含む。かかる実施形態によれば、ロック動作機構がリターンスプリングを含むことから、操作子を操作しない限り、ロック部材がロック位置にされる、したがって、ロックが不用意に解除されることがない。   The operation element is not particularly limited as long as the operation member is operated from the original position to the operation position and simultaneously releases the one lock member and the other lock member. The operating element may be manually returned from the operating position to the original position, but is preferably automatically returned from the operating position to the original position. For example, when the operating element is operated from the original position to the operating position, the one locking member and the other locking member are moved from the locked position to the free position, and the lock operation mechanism includes a return spring that returns the operating element to the original position. In addition. According to such an embodiment, since the lock operation mechanism includes the return spring, the lock member is brought into the lock position unless the operation element is operated. Therefore, the lock is not inadvertently released.

双方のロック部材を動かすロック動作機構の構造は双方のロック部材を同時に動かすものであれば特に限定されず、双方のロック部材と機械的にリンクする機構であっても、電動式であってもよい。好ましい実施形態として、一方ロック部材および他方ロック部材は、貫通孔がそれぞれ形成され、これらの貫通孔を共通する１本の連結ピンが貫通し、中央連結部材は連結ピンの両端と係合する中央案内部が形成され、連結ピンは中央案内部に沿って移動する。かかる実施形態によれば、一方ロック部材および他方ロック部材を１本の連結ピンが共通して貫通することから、一方ロック部材および他方ロック部材がピンで連結されて連動することができる。したがってロック動作機構として、双方のロック機構を同時に解除する構造を好適に実現することが可能になる。   The structure of the lock operation mechanism for moving both lock members is not particularly limited as long as both lock members are moved simultaneously. The mechanism may be mechanically linked to both lock members or electrically operated. Good. As a preferred embodiment, each of the one lock member and the other lock member has through holes formed therein, a common connecting pin passes through these through holes, and the central connecting member engages with both ends of the connecting pin. A guide portion is formed, and the connecting pin moves along the central guide portion. According to this embodiment, since one connection pin penetrates the one lock member and the other lock member in common, the one lock member and the other lock member can be connected by the pin and interlocked. Therefore, it is possible to preferably realize a structure that simultaneously releases both lock mechanisms as the lock operation mechanism.

双方のロック部材を同時に動かすに際して、これらロック部材の挙動は特に限定されず、異なる挙動であってもよいし、同じ挙動であってもよい。より好ましい実施形態として、一方ロック部材は中央連結部材の一方に配置され、他方ロック部材は中央連結部材の他方に配置され、中央連結部材の中央を通過する仮想の中心面に関してこれら一方ロック部材および他方ロック部材は対称形状かつ対称配置され、連結ピンは中心面に沿ってピン延在方向と直角に移動する。かかる実施形態によれば、双方のロック部材が中心面に関して対称に挙動することから、双方のロック機構を同時に解除する構造を好適に実現することが可能になる。   When moving both locking members simultaneously, the behavior of these locking members is not particularly limited, and may be different or the same. In a more preferred embodiment, the one locking member is disposed on one of the central coupling members, and the other locking member is disposed on the other of the central coupling members, and these one locking member and the virtual central plane passing through the center of the central coupling member and On the other hand, the lock member is symmetrically arranged and symmetrically arranged, and the connecting pin moves along the center plane at right angles to the pin extending direction. According to this embodiment, since both the locking members behave symmetrically with respect to the center plane, it is possible to suitably realize a structure for simultaneously releasing both the locking mechanisms.

本発明は１実施形態に限定されないが、好ましくは、一方ロック部材は連結ピンと平行に延びる一方支持ピンおよび一方支持ピンの延在方向に対して傾斜する傾斜面が設けられ、他方ロック部材は連結ピンと平行に延びる他方支持ピンおよび他方支持ピンの延在方向に対して傾斜する傾斜面が設けられ、中央連結部材は中心面に関し一方および他方に対称配置される対称形状の一方案内部および他方案内部が形成され、一方案内部は一方支持ピンの両端と係合して、一方支持ピンをピン延在方向と直角に案内し、他方案内部は他方支持ピンの両端と係合して、他方支持ピンをピン延在方向と直角に案内し、操作子は傾斜面にそれぞれ当接する１対の脚部を有し、操作子が操作されることにより、脚部が支持ピンの延在方向に前進して傾斜面を同時に押し込み一方ロック部材および他方ロック部材を動かす。   Although the present invention is not limited to one embodiment, preferably, one lock member is provided with one support pin extending in parallel with the connection pin and an inclined surface inclined with respect to the extending direction of the one support pin, and the other lock member is connected. The other support pin that extends in parallel with the pin and the inclined surface that is inclined with respect to the extending direction of the other support pin are provided, and the central connecting member is symmetrically arranged on one side and the other on the other side, and the symmetrical one guide portion and the other plan The inside is formed, one guide part is engaged with both ends of one support pin, one support pin is guided at right angles to the pin extending direction, and the other guide part is engaged with both ends of the other support pin. The support pin is guided at right angles to the pin extending direction, and the operation element has a pair of leg portions that respectively contact the inclined surface. When the operation element is operated, the leg portion extends in the extending direction of the support pin. Move forward and tilt the surface On the other hand push when moving the locking member and the other lock member.

かかる実施形態によれば、双方のロック部材が中心面に関して対称に挙動することから、双方のロック機構を同時に解除する構造を好適に実現することが可能になる。しかも操作子の脚部が支持ピンの延在方向に前進して一方ロック部材の傾斜面および他方ロック部材の傾斜面を同時に押し込む。したがって、操作子のピン延在方向の前進をロック部材のピン直角方向の動きに変換することが可能となることから、操作子の操作によって確実にロックを解除することができる。   According to this embodiment, since both the locking members behave symmetrically with respect to the center plane, it is possible to suitably realize a structure for simultaneously releasing both the locking mechanisms. Moreover, the leg portion of the operating element advances in the extending direction of the support pin and simultaneously pushes the inclined surface of the one lock member and the inclined surface of the other lock member. Therefore, since the advancement of the operating element in the pin extending direction can be converted into the movement of the lock member in the direction perpendicular to the pin, the lock can be reliably released by operating the operating element.

好ましい実施形態として、一方ロック部材および他方ロック部材は、傾斜面に隣接して連結ピンと平行な面がそれぞれ設けられ、傾斜面を押し込んだ脚部は、さらに前進しこれらの平行面と平行に延びて接触する。かかる実施形態によれば、一方ロック部材および他方ロック部材が何らかの力を受けて脚部を押す場合であっても、脚部は一方ロック部材および他方ロック部材によって動かされることはなく、一方ロック部材および他方ロック部材のフリー位置を保持することができる。   As a preferred embodiment, each of the one lock member and the other lock member is provided with a plane parallel to the connecting pin adjacent to the inclined surface, and the leg portion that has pushed the inclined surface further advances and extends parallel to these parallel surfaces. Touch. According to this embodiment, even when the one lock member and the other lock member receive some force and pushes the leg, the leg is not moved by the one lock member and the other lock member. And the free position of the other lock member can be held.

柱材は少なくとも上下方向に延びていればよく、上下方向と交差して延びる斜材で有ってもよい。また柱材の本数は特に限定されない。例えば乳幼児収容空間が平面視長方形のプレイヤードであれば、４角にそれぞれ１本ずつの柱材を有する。あるいは六角形など、平面視多角形のプレイヤードであれば、各角にそれぞれ１本ずつの柱材を有してもよい。２本以上の柱材を互いに連結する横材は、少なくとも水平方向に延びていればよく、水平方向と交差して延びる斜材で有ってもよい。つまりフレーム構造体の概略形状は、平面視において特に限定されず、長方形や正方形などの矩形であればよい。あるいは正六角形や正八角形など偶数個の角部を有する正多角形であってもよい。あるいは正六角形や正八角形のうち対向する２辺を他の辺よりも長く伸ばした等角多角形であってもよい。端的に表現すれば、フレーム構造体は平面視において矩形または偶数個の角部を有する等角多角形を構成する。１実施形態として、乳幼児収容空間は平面視において矩形を構成し、柱材は矩形の角部にそれぞれ配置され、横材は平面視において互いに平行な２本１対の矩形の辺を構成するよう配置される。   The column material only needs to extend at least in the vertical direction, and may be a diagonal material that extends across the vertical direction. Further, the number of column members is not particularly limited. For example, if the infant storage space is a playard having a rectangular shape in plan view, each of the four corners has one column member. Or if it is a polygonal planar playard, such as a hexagon, it may have one pillar material at each corner. The cross member that connects two or more column members to each other only needs to extend at least in the horizontal direction, and may be a diagonal member that extends across the horizontal direction. That is, the schematic shape of the frame structure is not particularly limited in plan view, and may be a rectangle such as a rectangle or a square. Alternatively, it may be a regular polygon having an even number of corners such as a regular hexagon or a regular octagon. Or the equilateral polygon which extended two opposite sides longer than another side among regular hexagons and regular octagons may be sufficient. In short, the frame structure constitutes a rectangular or an equiangular polygon having an even number of corners in plan view. As one embodiment, the infant storage space has a rectangular shape in plan view, the column members are arranged at the corners of the rectangle, and the cross members form a pair of rectangular sides parallel to each other in the plan view. Be placed.

かかる実施形態によれば、中程で折れ変形可能な横材が、平面視において長方形・正方形など矩形の乳幼児収容空間を形成するフレーム構造体の横材のうち、２本１対の矩形の辺を構成するようが配置されることから、折り畳みの際には効率よく折れ変形させて、フレーム構造体を横材の長手方向に縮小することができる。つまり横材は互いに平行となるよう配置されることから、例えば矩形のフレーム構造体にあっては、短辺同士を効率よく折れ変形させることができ、フレーム構造体を短辺方向に縮小させることができる。あるいは長辺同士を効率よく折れ変形させることができ、フレーム構造体を長辺方向に縮小させることができる。あるいは短辺および長辺のすべてを折れ変形させることができ、フレーム構造体を短辺方向および長辺方向に縮小させることができる。同様に正多角形のフレーム構造体にあっては、互いに平行となるよう配置される２辺１対の横材を効率よく折れ変形させることができ、フレーム構造体をこれら２辺の延在方向に縮小させることができる。   According to such an embodiment, the transverse member that can be bent and deformed in the middle is a pair of rectangular sides of the transverse member of the frame structure that forms a rectangular infant storage space such as a rectangle or a square in plan view. Thus, the frame structure can be reduced in the longitudinal direction of the cross member by efficiently folding and deforming when folded. In other words, since the cross members are arranged so as to be parallel to each other, for example, in the case of a rectangular frame structure, the short sides can be efficiently folded and deformed, and the frame structure can be reduced in the short side direction. Can do. Alternatively, the long sides can be efficiently folded and deformed, and the frame structure can be reduced in the long side direction. Alternatively, all of the short side and the long side can be bent and deformed, and the frame structure can be reduced in the short side direction and the long side direction. Similarly, in the case of a regular polygonal frame structure, a pair of two side members arranged so as to be parallel to each other can be efficiently folded and deformed, and the extension direction of these two sides can be reduced. Can be reduced.

なお上述した本発明の中程で折れ変形可能な横材は上述の配置に限定されず、平面視においてフレーム構造体のすべての横材に配置されてもよいし、すべての横材のうちの幾つかの横材に配置されてもよい。またかかる実施形態の他にも、フレーム構造体は正五角形や正七角形など奇数個の角部を有する正多角形であって、横材がすべての辺に配置されてもよい。   The cross member that can be bent and deformed in the middle of the present invention described above is not limited to the above-described arrangement, and may be arranged on all the cross members of the frame structure in a plan view. It may be arranged on several cross members. In addition to this embodiment, the frame structure may be a regular polygon having an odd number of corners such as a regular pentagon and a regular heptagon, and the cross members may be arranged on all sides.

このように本発明は、長手方向一方部材と中央連結部材を相対回動不能にする一方ロック機構と、長手方向他方部材と中央連結部材を相対回動不能にする他方ロック機構と、これら双方のロック機構を同時に解除して双方のロック解除を保持するロック動作機構を有することから、乳幼児の保護者がロック動作機構を解除操作すると、一方側ロック機構も他方側ロック機構も確実にロック解除される。これにより、プレイヤードが展開された使用状態では横材が不用意に折り畳まないようロックされる。したがって、プレイヤードの使用状態にあっては横材が折れ変形することがなく、フレーム構造体は使用状態におけるプレイヤードの骨組の役目を確実に果たす。そして複数本の横材を同時に折れ変形させる作業を伴うプレイヤードの折り畳み操作の際、一方側ロック機構をロック解除すれば他方側ロック機構も確実にロック解除される。したがって、乳幼児の保護者がプレイヤードの折り畳み操作を容易・迅速・確実に行うことができる。   As described above, the present invention includes a lock mechanism that disables relative rotation of the one longitudinal member and the central connecting member, and a lock mechanism that disables relative rotation of the other longitudinal member and the central connecting member. Since it has a lock operation mechanism that releases the lock mechanism at the same time and holds both unlocks, when the guardian of the infant releases the lock operation mechanism, both the one side lock mechanism and the other side lock mechanism are reliably unlocked. The As a result, the cross member is locked so as not to be folded carelessly in the use state where the playard is unfolded. Therefore, the cross member does not bend and deform when the playerd is in use, and the frame structure reliably plays the role of the framework of the playerd in use. When the player's folding operation involving the work of simultaneously bending and deforming a plurality of cross members is performed, if the one side lock mechanism is unlocked, the other side lock mechanism is also reliably unlocked. Therefore, the infant guardian can easily, quickly, and surely perform the folding operation of the playard.

以下、本発明の実施の形態を、図面に示す実施例に基づき詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail based on examples shown in the drawings.

図１〜図７は、本発明の一実施例になるプレイヤードの全体概略を示す。このうち図１〜図４はプレイヤードが展開された使用状態を示し、図５〜図７はプレイヤードの折り畳み状態を模式的に示す。プレイヤード１０は、プレイヤード１０の骨格を構成するフレーム構造体１１と、フレーム構造体１１に取り付けられてフレーム構造体１１の外周を包囲する布状部材１２と、フレーム構造体１１に着脱可能に取り付けられた棒部材１３と、棒部材１３に支持される敷板４１とを備える。   1 to 7 show an overall outline of a playard according to an embodiment of the present invention. Among these, FIGS. 1 to 4 show the use state in which the playard is unfolded, and FIGS. 5 to 7 schematically show the folded state of the playard. The playerd 10 is detachably attached to the frame structure 11, a frame structure 11 constituting the skeleton of the playerd 10, a cloth-like member 12 attached to the frame structure 11 and surrounding the outer periphery of the frame structure 11, and the frame structure 11. The attached bar member 13 and a floor plate 41 supported by the bar member 13 are provided.

本実施例のプレイヤード１０は、平面視略長方形であるため、便宜上、１対の長辺部分をプレイヤード一方側、プレイヤード他方側、プレイヤード左側、プレイヤード右側、プレイヤード側部、プレイヤード両側部、もしくはプレイヤード左右側部と称する。また１対の短辺部分をプレイヤード一端部、プレイヤード他端部、プレイヤード前端部、プレイヤード後端部、プレイヤード端部、プレイヤード両端部、もしくはプレイヤード前後端部と称する。プレイヤード１０は、乳幼児を遊ばせる枠囲いとして使用できるほか、後述するように乳幼児を寝かせる寝台としても好適に使用可能である。   Since the playerd 10 of the present embodiment has a substantially rectangular shape in plan view, for convenience, a pair of long sides are arranged on one side of the playerd, the other side of the playerd, the left side of the playered, the right side of the playered, the side of the playered, This is referred to as both side portions or left and right side portions. The pair of short sides are referred to as one end of the playerd, the other end of the playerd, the front end of the playerd, the rear end of the playerd, the playerd end, both ends of the playered, or the front and rear ends of the playered. The playard 10 can be used not only as a frame enclosure for playing infants, but also as a bed for sleeping infants as will be described later.

まずフレーム構造体１１につき説明すると、フレーム構造体１１は乳幼児を収容する空間の周囲を取り囲むように形成され、上下方向に延びる４本の柱材１４と、プレイヤード両側部に設けられた１対の横材１５Ｌ，１５Ｒと、プレイヤード両端部に設けられた１対の横材１６，１６と、平面視において対角線となるよう配置されたクロスパイプ１７とを含む。平面視において、複数の柱材１４は乳幼児を収容する空間の外周に配置され、横材１５Ｌ，１５Ｒ,１６は隣り合う柱材１４，１４同士を互いに連結する。   First, the frame structure 11 will be described. The frame structure 11 is formed so as to surround a space for accommodating an infant, and is provided with four pillar members 14 extending in the vertical direction and a pair provided on both sides of the playard. Cross members 15L, 15R, a pair of cross members 16, 16 provided at both ends of the playard, and a cross pipe 17 arranged to be diagonal in plan view. In plan view, the plurality of column members 14 are arranged on the outer periphery of the space for accommodating the infant, and the cross members 15L, 15R, 16 connect the adjacent column members 14, 14 to each other.

柱材１４は平面視において長方形となる乳幼児収容空間の四隅の角部で直立するよう配置される。プレイヤード一端部に配置された２本の柱材１４，１４間には、横材１６が架設される。同様に、プレイヤード他端部に配置された２本の柱材１４，１４間にも、横材１６が架設される。同様に、プレイヤード一方側に配置された２本の柱材１４，１４間には、横材１５Ｒが架設される。具体的には、横材１６，１５Ｒの端部は柱材１４の上端部ブロック１４Ｂと回動可能に連結し、プレイヤードの折り畳み時には、横材１６,１５Ｒが柱材１４に近づくよう回動可能である。また横材１６は、中央部に設けられた中央連結部材２０と、中央連結部材２０から長手方向一方へ延びるパイプ１６１と、中央連結部材２０から長手方向他方へ延びるパイプ１６２とで構成される。パイプ１６１およびパイプ１６２は同じ長さの棒部材である。   The column members 14 are arranged so as to stand upright at the corners of the four corners of the infant accommodating space which is rectangular in plan view. A cross member 16 is installed between the two column members 14 and 14 arranged at one end of the playard. Similarly, a cross member 16 is also installed between the two column members 14 and 14 arranged at the other end of the playard. Similarly, a cross member 15R is installed between two pillar members 14 and 14 arranged on one side of the playard. Specifically, the end portions of the cross members 16 and 15R are rotatably connected to the upper end block 14B of the column member 14, and are rotated so that the cross members 16 and 15R approach the column member 14 when the playerd is folded. Is possible. The cross member 16 includes a central connecting member 20 provided at the center, a pipe 161 extending from the central connecting member 20 in one longitudinal direction, and a pipe 162 extending from the central connecting member 20 in the other longitudinal direction. The pipe 161 and the pipe 162 are bar members having the same length.

また横材１５Ｒは、中央部に設けられた中央連結部材２０と、中央連結部材２０から長手方向一方へ延びるパイプ１５１と、中央連結部材２０から長手方向他方へ延びるパイプ１５２とで構成される。パイプ１５１およびパイプ１５２は同じ長さの棒部材であり、パイプ１６１，１６２よりも長い。   The cross member 15R includes a central connecting member 20 provided at the center, a pipe 151 extending from the central connecting member 20 in one longitudinal direction, and a pipe 152 extending from the central connecting member 20 in the other longitudinal direction. The pipe 151 and the pipe 152 are rod members having the same length, and are longer than the pipes 161 and 162.

プレイヤード両端部に設けられた２本１対の横材１６，１６は平面視において矩形となる乳幼児保護空間の２本１対の短辺を構成する。プレイヤード両側部に設けられた２本１対の横材１５Ｌ，１５Ｒは乳幼児保護空間の２本１対の長辺を構成する。   The pair of cross members 16, 16 provided at both ends of the playard constitutes a pair of short sides of the infant protection space that is rectangular in plan view. Two pairs of cross members 15L, 15R provided on both sides of the playard constitute two pairs of long sides of the infant protection space.

プレイヤードの使用状態において、中央連結部材２０は中央連結部材２０から長手方向一方へ延びるパイプ１６１および長手方向他方へ延びるパイプ１６２をロックし、横材１６は図３に示すように一直線に保持される。しかし中央連結部材２０のロックを解除すると横材１６が中央部で折れ変形可能にされる。したがって、プレイヤード１０を折り畳むと横材１６が中央部で折れ変形する。そして後述する図６に示すように、中央連結部材２０からパイプ１６１，１６２が上方へ延び、横材１６はＶ字形状にされる。横材１５Ｒも同様に中央連結部材２０が設けられ、プレイヤードの使用状態では一直線にされ、プレイヤードの折り畳み状態では中央部で折れ変形する。そして中央連結部材２０からパイプ１５１，１５２が上方へ延び、横材１５ＲはＶ字形状にされる。   In the use state of the playard, the central connecting member 20 locks the pipe 161 extending in the longitudinal direction from the central connecting member 20 and the pipe 162 extending in the other longitudinal direction, and the cross member 16 is held in a straight line as shown in FIG. The However, when the lock of the center connecting member 20 is released, the cross member 16 can be bent and deformed at the center. Therefore, when the playard 10 is folded, the cross member 16 is bent and deformed at the center. Then, as shown in FIG. 6 described later, pipes 161 and 162 extend upward from the central connecting member 20, and the cross member 16 is formed in a V shape. Similarly, the cross member 15R is provided with a central connecting member 20, which is straight when the playerd is used, and is bent and deformed at the center when the playerd is folded. The pipes 151 and 152 extend upward from the central connecting member 20, and the cross member 15R is formed in a V shape.

横材１５Ｌも同様に中央連結部材２０が設けられ、プレイヤードの使用状態において図２に示すように一直線に延びている。しかしプレイヤードの折り畳み状態では中央部で折れ変形する。そして後述する図５に示すように、中央連結部材２０からパイプ１５１，１５２が上方へ延び、横材１５ＬはＶ字形状にされる。   Similarly, the cross member 15L is provided with a central connecting member 20 and extends in a straight line as shown in FIG. However, in the folded state of playard, it folds and deforms in the center. And as shown in FIG. 5 mentioned later, the pipes 151 and 152 are extended upwards from the center connection member 20, and the cross member 15L is made into V shape.

なお、複数本の横材のうち横材１５Ｌのみ、プレイヤード右側２箇所のスライド部材１８を介して、柱材１４に回動可能かつ摺動可能に連結される。具体的には、スライド部材１８に上下方向に延びる貫通孔が形成されて、この貫通孔に柱材１４が貫通し、１対のスライド部材１８は柱材１４に沿って摺動可能である。通常、スライド部材１８は留め具１９で摺動不能にされており、スライド部材１８がプレイヤード右側に配置された１対の柱材１４の上端部にそれぞれ固定される。またスライド部材１８は横材１５Ｌの端部と回動可能に連結し、プレイヤードの折り畳み時には横材１５Ｌが柱材１４に近づくよう回動可能である。なお、横材１５Ｌの長手方向一方のパイプ１５１は横材１５Ｒの長手方向一方のパイプ１５１よりもスライド部材１８の寸法分短くされる。同様に横材１５Ｌの長手方向他方のパイプ１５２は横材１５Ｒの長手方向他方のパイプ１５２よりもスライド部材１８の寸法分短くされる。   Of the plurality of cross members, only the cross member 15L is rotatably and slidably connected to the column member 14 via the slide members 18 at two places on the right side of the playard. Specifically, a through hole extending in the vertical direction is formed in the slide member 18, and the column member 14 penetrates through the through hole, and the pair of slide members 18 can slide along the column member 14. Usually, the slide member 18 is made non-slidable by a fastener 19, and the slide member 18 is fixed to the upper end portions of a pair of column members 14 arranged on the right side of the playard. Further, the slide member 18 is rotatably connected to the end of the cross member 15L, and can be rotated so that the cross member 15L approaches the column member 14 when the playerd is folded. Note that one pipe 151 in the longitudinal direction of the cross member 15L is shorter than the one pipe 151 in the longitudinal direction of the cross member 15R by the dimension of the slide member 18. Similarly, the other pipe 152 in the longitudinal direction of the cross member 15L is made shorter by the dimension of the slide member 18 than the other pipe 152 in the longitudinal direction of the cross member 15R.

留め具１９を緩めて１対のスライド部材１８を摺動可能とすると、図２に矢で示すように横材１５Ｌは１対のスライド部材１８とともに下方へ移動し、図２に二点鎖線で示す位置にされ得る。これにより、プレイヤード１０への乳幼児の出し入れが容易になり、保護者はプレイヤード１０内の乳幼児に簡単に手をのばすことができる。なお保護者からみて横材１５Ｌは４本の横材のうち最も近い位置にあることから、前枠とも称する。   When the fastener 19 is loosened so that the pair of slide members 18 can slide, the cross member 15L moves downward together with the pair of slide members 18 as shown by arrows in FIG. It can be in the position shown. Thereby, the baby can be easily put in and out of the playard 10, and the guardian can easily reach out to the baby in the playard 10. Note that the cross member 15L is also referred to as a front frame because it is in the closest position among the four cross members as viewed from the guardian.

クロスパイプ１７は、Ｘ字形状であって、図４に示すように長方形のプレイヤード１０下面で、対角線状に配置される。クロスパイプ１７は、具体的に、Ｘ字の中央に配置された中央連結部材２３と、中央連結部材２３および各柱材１４と連結する４本のパイプ１７１〜１７４で構成される。パイプ１７１〜１７４の一方端は柱材１４とそれぞれ回動可能に連結する。またパイプ１７１〜１７４の他方端は中央連結部材２３とそれぞれ回動可能に連結する。図面の理解を容易にするため、図２および図３では中央連結部材２３の一部を断面にして表す。中央連結部材２３は、４本のパイプ１７１〜１７４が中央連結部材２３の下方へ向かうよう回動することを許容するが、中央連結部材２３の上方へ向かうよう回動することを規制する。プレイヤードの使用状態においてクロスパイプ１７はＸ字に展開された状態を保持することができる。また図５〜図７に示すように、プレイヤードの折り畳み状態において、４本のパイプ１７１〜１７４は中央連結部材２３の下方に集約され、クロスパイプ１７は小さく折り畳まれる。   The cross pipe 17 has an X shape, and is arranged diagonally on the lower surface of the rectangular playerd 10 as shown in FIG. Specifically, the cross pipe 17 includes a central connecting member 23 disposed in the center of the X-shape, and four pipes 171 to 174 connected to the central connecting member 23 and each column member 14. One ends of the pipes 171 to 174 are rotatably connected to the column member 14. Further, the other ends of the pipes 171 to 174 are rotatably connected to the central connecting member 23. In order to facilitate understanding of the drawings, a part of the central connecting member 23 is shown in a cross section in FIGS. The central connection member 23 allows the four pipes 171 to 174 to rotate downward toward the central connection member 23, but restricts rotation toward the upper direction of the central connection member 23. In the use state of the playard, the cross pipe 17 can maintain a state of being developed in an X shape. As shown in FIGS. 5 to 7, in the folded state of the playard, the four pipes 171 to 174 are gathered below the central connecting member 23, and the cross pipe 17 is folded small.

プレイヤード他端に配置された２本の柱材１４，１４の下端には、車輪２１と、車輪２１の外周を包囲する車輪カバー２２が設けられる。車輪２１は車輪カバー２２の下端から突出してプレイヤード設置床面Ｓに接地する。また図２を参照して、車輪カバー２２のうちプレイヤード内側の一部２２ｓは、車輪カバー２２のうちプレイヤード外側の一部よりもさらに下方へ突出してプレイヤード設置床面Ｓに接地する。このため、プレイヤード設置床面Ｓにすべての柱材１４を接地させる通常の使用状態においては、車輪２１がプレイヤード設置床面Ｓで転動することが阻止される。   A wheel 21 and a wheel cover 22 that surrounds the outer periphery of the wheel 21 are provided at the lower ends of the two pillar members 14 and 14 arranged at the other end of the playard. The wheel 21 protrudes from the lower end of the wheel cover 22 and contacts the playd installation floor surface S. Referring to FIG. 2, a part 22 s of the wheel cover 22 on the inner side of the playerd protrudes further downward than a part of the wheel cover 22 on the outer side of the playerd, and comes into contact with the playerd installation floor S. For this reason, the wheel 21 is prevented from rolling on the playerd installation floor surface S in a normal use state in which all the column members 14 are grounded on the playerd installation floor surface S.

しかしながらプレイヤード１０を使用しないときなど、図２および図５の紙面左側に示されるプレイヤード１０の一端部Ａを持ち上げると、車輪カバー突出部２２ｓが設置床面Ｓから離れるとともの車輪２１が設置床面Ｓに接地する。このため、展開された状態および折り畳み状態のプレイヤード１０を傾け、プレイヤード一端部の柱材１４を床面Ｓから離し、プレイヤード他端部の柱材１４下端の車輪２１のみを接地させることによって容易にプレイヤード１０を運搬することができる。   However, when the playerd 10 is not used, when one end A of the playerd 10 shown on the left side of the paper surface of FIGS. 2 and 5 is lifted, the wheel 21 with the wheel cover protrusion 22s being separated from the installation floor surface S is formed. Ground the installation floor S. For this reason, the playerd 10 in the unfolded state and the folded state is tilted, the pillar member 14 at one end of the playerd is separated from the floor surface S, and only the wheel 21 at the lower end of the pillar member 14 at the other end of the playerd is grounded. Thus, the playerd 10 can be easily transported.

これまで説明したように、横材１５Ｌ，１５Ｒ,１６は中央部でそれぞれ折れ変形可能であり、クロスパイプ１７は中央部で折れ変形可能であり、横材１５Ｌ，１５Ｒ,１６およびクロスパイプ１７の端部は柱材１４と回動可能に連結することから、フレーム構造体１１は、図１〜図５に示す展開された使用状態と、図６に示す折り畳み状態の２形態に変形することができる。   As described so far, the cross members 15L, 15R, 16 can be bent and deformed at the central portion, and the cross pipe 17 can be bent and deformed at the central portion, and the cross members 17L, 15R, 16 and the cross pipe 17 can be deformed. Since the end portion is rotatably connected to the column member 14, the frame structure 11 can be deformed into two forms, that is, a deployed state shown in FIGS. 1 to 5 and a folded state shown in FIG. it can.

次に布状部材１２につき説明すると、布状部材１２は数ｍｍ程度の網目のネットや、布地などの素材で形成され、４本の柱部材１４の間の４面にそれぞれ張設される。そして布状部材１２の上端は横材１５Ｌ，１５Ｒ，１６に吊り下げられる。また布状部材１２の下端はクロスパイプ１７と略同じ高さ位置にある。これにより布状部材１２、クロスパイプ１７よりも上方に設けられる敷板４１を確実に囲繞する。   Next, the cloth-like member 12 will be described. The cloth-like member 12 is formed of a material such as a net having a mesh of about several millimeters or a cloth, and is stretched on four surfaces between the four column members 14. The upper end of the cloth-like member 12 is suspended from the cross members 15L, 15R, and 16. Further, the lower end of the cloth-like member 12 is at substantially the same height as the cross pipe 17. Thus, the floor plate 41 provided above the cloth-like member 12 and the cross pipe 17 is surely surrounded.

次に棒部材１３につき説明すると、棒部材１３は、プレイヤード両側部において直線状に延びる１対の棒状体であって、水平な姿勢にされて、両端が柱材１４に取り付けられる。棒部材１３は、図２に実線および二点鎖線で示すように、柱材１４の下端部および中央部に選択的に取り付けることができる。   Next, the rod member 13 will be described. The rod member 13 is a pair of rod-like bodies that extend linearly on both sides of the playard, and is placed in a horizontal posture, and both ends are attached to the column member 14. The bar member 13 can be selectively attached to the lower end portion and the center portion of the column member 14 as shown by a solid line and a two-dot chain line in FIG.

すなわち図２および図３を参照して、各柱材１４には高さ位置の異なる２個のブラケット３１,３２が取付固定される。ブラケット３１は柱材の下端領域にあってクロスパイプ１７よりもやや上方に固定される。ブラケット３２は、クロスパイプ１７の中央部に固定される。ブラケット３１，３２は棒部材１３の端部を支持する。硬質の棒部材１３は乳幼児の荷重に加え乳幼児が活発に動く際の衝撃荷重にも耐え得るよう十分な曲げ強度およびせん断強度を有するパイプであり、両端部を除く中央領域が敷板４１下面に沿って延び、両端部がブラケット３１，３２に取り付けられる。これにより棒部材１３は、敷板４１上面に乗せられる乳幼児を安定して支持する。そして乳幼児が敷板の上で活発に活動しても、横材１５Ｌ，１５Ｒ，１６が折れ変形することを防止することができる。   That is, referring to FIG. 2 and FIG. 3, two brackets 31 and 32 having different height positions are attached and fixed to each column member 14. The bracket 31 is in the lower end region of the column member and is fixed slightly above the cross pipe 17. The bracket 32 is fixed to the center portion of the cross pipe 17. The brackets 31 and 32 support the end of the bar member 13. The hard bar member 13 is a pipe having sufficient bending strength and shear strength to withstand the impact load when the infant actively moves in addition to the infant load, and the central region excluding both ends extends along the bottom surface of the floor plate 41. The both ends are attached to the brackets 31 and 32. Thereby, the bar member 13 stably supports the infant placed on the top surface of the floor plate 41. Even if the infant is actively active on the floorboard, the cross members 15L, 15R, 16 can be prevented from being bent and deformed.

次に中央連結部材２０およびパイプ１５１，１５２を有するプレイヤード両側部の横材１５Ｌ，１５Ｒと、中央連結部材２０およびパイプ１６１，１６２を有するプレイヤード両端部の横材１６，１６につき詳細に説明する。なお、これらの横材１５Ｌ，１５Ｒ，１６はパイプの長さが異なるだけであり、中央連結部材２０における折れ変形の機構についてはすべて共通するため、代表して横材１６につき説明する。   Next, the cross members 15L and 15R on both sides of the playered having the central connecting member 20 and the pipes 151 and 152 and the cross members 16 and 16 on both ends of the playered having the central connecting member 20 and the pipes 161 and 162 will be described in detail. To do. These cross members 15L, 15R and 16 differ only in the length of the pipe, and all the bending deformation mechanisms in the central connecting member 20 are common, so the cross member 16 will be described as a representative.

図８は横材の中央部を取り出して示す平面図であり、中央連結部材２０を断面にして表す。図９は横材の中央部を取り出して示す正面図であり、紙面右側は一部断面で表される。図１０は、図８のＸ−Ｘにおける断面を示す説明図である。図１１は、図８のＸＩ−ＸＩにおける断面を示す説明図である。これら図８〜図１１はすべて回動不能にロックされた状態を表す。図１２は中央連結部材を取り出して示す正面図である。   FIG. 8 is a plan view showing the central portion of the cross member taken out, and shows the central connecting member 20 in cross section. FIG. 9 is a front view showing the center part of the cross member taken out, and the right side of the drawing is partially shown in cross section.

FIG. 12 is a front view showing the center connecting member taken out.

横材１６は、長手方向一方部材になるパイプ１６１と、長手方向他方部材になるパイプ１６２と、長手方向中央部にあってこれらパイプ１６１およびパイプ１６２と回動可能に連結する中央連結部材２０と、パイプ１６１と中央連結部材２０を相対回動不能にする一方ロック機構としての一方ロック部材２４１と、パイプ１６２と中央連結部材２０を相対回動不能にする他方ロック機構としての他方ロック部材２４２と、これら双方のロック機構を同時に解除して双方のロック解除を保持するロック動作機構としてのボタン２５を有する。   The cross member 16 includes a pipe 161 that is one member in the longitudinal direction, a pipe 162 that is the other member in the longitudinal direction, and a central coupling member 20 that is pivotally coupled to the pipe 161 and the pipe 162 at the center in the longitudinal direction. The one lock member 241 as one lock mechanism that makes the pipe 161 and the central coupling member 20 non-rotatable relative to each other, and the other lock member 242 as the other lock mechanism that makes the pipe 162 and the central coupling member 20 non-rotatable relative to each other. In addition, a button 25 serving as a lock operation mechanism that simultaneously releases both the lock mechanisms and holds both lock releases is provided.

説明の便宜のため、中央連結部材２０からみてパイプ１６１を左方とし、パイプ１６２を右方として、以下、左右方向と称する。図８および図９に示すように、中央連結部材２０は左右方向中央を通過する中心線Ｃに関し左右対称に形成され、パイプ１６１およびパイプ１６２中心線Ｃに関し左右対称に配置される。   For convenience of explanation, the pipe 161 is set to the left and the pipe 162 is set to the right as viewed from the central connecting member 20, and hereinafter referred to as the left-right direction. As shown in FIGS. 8 and 9, the central connecting member 20 is formed symmetrically with respect to the center line C passing through the center in the left-right direction, and is disposed symmetrically with respect to the center line C of the pipe 161 and the pipe 162.

図９に示すように、パイプ１６１の両端のうち、長手方向中央側の端部は連結軸２６１を介して中央連結部材２０の一方端と回動可能に連結する。またパイプ１６２の両端のうち、長手方向中央側の端部は連結軸２６２を介して中央連結部材２０の他方端と回動可能に連結する。中央連結部材２０は間隔を伴って対向する１対の壁部２０１，２０２を有する。これら壁部２０１，２０２には、連結軸２６１，２６２が架設される。なお図９に示されないパイプ１６１，１６２の他方端部は、柱材１４の上端部ブロック１４Ｂと回動可能に連結する。中央連結部材２０は中間壁部２０３をさらに有し、中間壁部２０３は１対の壁部２０１，２０２の上端とそれぞれ結合する。図１０および図１１の断面図に示すように、壁部２０１〜２０３は断面視コ字状に配置される。   As shown in FIG. 9, the end on the center side in the longitudinal direction of both ends of the pipe 161 is rotatably connected to one end of the central connecting member 20 via a connecting shaft 261. Of the both ends of the pipe 162, the end portion on the center side in the longitudinal direction is rotatably connected to the other end of the center connecting member 20 via the connecting shaft 262. The central connecting member 20 has a pair of wall portions 201 and 202 that face each other with a gap. Connection shafts 261 and 262 are installed on these wall portions 201 and 202. The other ends of the pipes 161 and 162 not shown in FIG. 9 are rotatably connected to the upper end block 14B of the column member 14. The central connecting member 20 further includes an intermediate wall 203, and the intermediate wall 203 is coupled to the upper ends of the pair of walls 201 and 202, respectively. As shown in the cross-sectional views of FIGS. 10 and 11, the wall portions 201 to 203 are arranged in a U shape in a cross-sectional view.

水平方向に延びるパイプ１６１は連結軸２６１よりも端部側で壁部２０３と当接することから、中央連結部材２０よりも下方への回動が規制される。これに対し、パイプ１６１は中央連結部材２０よりも上方への回動が許容される。しかしながらパイプ１６１は、連結軸２６１よりも端部側で一方ロック部材２４１と係合している間は上方への回動も規制され、これによりパイプ１６１は中央連結部材２０に対し相対回動不能にロックされる。   Since the pipe 161 extending in the horizontal direction comes into contact with the wall 203 on the end side of the connection shaft 261, the downward rotation of the central connection member 20 is restricted. On the other hand, the pipe 161 is allowed to turn upward from the central connecting member 20. However, while the pipe 161 is engaged with the one lock member 241 on the end side of the connecting shaft 261, the pipe 161 is also restricted from rotating upward, and thus the pipe 161 cannot be rotated relative to the central connecting member 20. Locked to.

水平方向に延びるパイプ１６２も連結軸２６２よりも端部側で壁部２０３と当接することから、中央連結部材２０よりも下方への回動が規制される。これに対し、パイプ１６２は中央連結部材２０よりも上方への回動が許容される。しかしながらパイプ１６２は、連結軸２６２よりも端部側で他方ロック部材２４２と係合している間は上方への回動も規制され、これによりパイプ１６２は中央連結部材２０に対し相対回動不能にロックされる。   Since the pipe 162 extending in the horizontal direction also comes into contact with the wall 203 on the end side of the connecting shaft 262, the downward rotation of the central connecting member 20 is restricted. On the other hand, the pipe 162 is allowed to turn upward from the central connecting member 20. However, the pipe 162 is also restricted from rotating upward while being engaged with the other lock member 242 on the end side of the connecting shaft 262, and thus the pipe 162 cannot be rotated relative to the central connecting member 20. Locked to.

図９に示すように、中央連結部材２０は互いに平行に延びる連結軸２６１，２６２からみて下方へ張り出しており、これらの連結軸２６１，２６２を含む仮想平面よりも下方にロック部材２４１，２４２が取り付けられる。   As shown in FIG. 9, the central connecting member 20 protrudes downward as viewed from connecting shafts 261 and 262 extending in parallel to each other, and the lock members 241 and 242 are located below a virtual plane including these connecting shafts 261 and 262. It is attached.

ここで付言すると、互いに平行に延びる連結軸２６１，２６２は中央連結部材２０の中央を通過する仮想の中心面に関して左右対称形状かつ左右対称配置となる。かかる中心面は図８、図９、図１２、および後述の図１３、図１４において中心線Ｃで表される。   In other words, the connecting shafts 261 and 262 extending in parallel with each other have a symmetrical shape and a symmetrical arrangement with respect to a virtual center plane passing through the center of the central connecting member 20. Such a center plane is represented by a center line C in FIGS. 8, 9, and 12 and later-described FIGS.

４本の横材１５Ｌ，１６，１５Ｒ，１６によって四方を包囲される乳幼児収容領域をプレイヤード内側とし、乳幼児収容領域の外をプレイヤード外側として、壁部２０２はプレイヤード内側に配置され、壁部２０１はプレイヤード外側に配置される。   The infant housing area surrounded by the four cross members 15L, 16, 15R, and 16 on the four sides is defined as the inside of the playd, the outside of the infant accommodating area is defined as the outside of the playerd, and the wall 202 is disposed on the inside of the playerd. The unit 201 is disposed outside the playard.

壁部２０１の内外両面のうち壁部２０２から遠い側の外側面には、センターロックカバー３０が取付固定される。図９に示すようにセンターロックカバー３０は正面視で楕円形状であり、図８、図１０、図１１に示すように外縁から中央にむかって外側へ膨らんだ立体的形状である。センターロックカバー３０の中央にはセンター孔３０ｈが形成される。センター孔３０ｈは壁部２０１の垂直方向に延び、ボタン２５を収容する。プレイヤード１０の使用状態でボタン２５は通常、図８、図１０、図１１に示すように壁部２０１から離れた原位置にされている。ボタン２５には壁部２０２に向かって突出する脚部２５１，２５２が設けられる。図８に示すように、脚部２５１，２５２は左右方向中央を通過する中心線Ｃに関し左右対称に配置されて、脚部２５１，２５２先端が、壁部２０１に穿設された１対の貫通孔２０ｃをそれぞれ貫通する。   The center lock cover 30 is attached and fixed to the outer surface on the side far from the wall portion 202 of both the inner and outer surfaces of the wall portion 201. As shown in FIG. 9, the center lock cover 30 has an elliptical shape when viewed from the front, and has a three-dimensional shape that bulges outward from the outer edge toward the center as shown in FIGS. A center hole 30 h is formed in the center of the center lock cover 30. The center hole 30 h extends in the vertical direction of the wall portion 201 and accommodates the button 25. When the playerd 10 is in use, the button 25 is normally in the original position away from the wall 201 as shown in FIGS. The button 25 is provided with leg portions 251 and 252 protruding toward the wall portion 202. As shown in FIG. 8, the leg portions 251 and 252 are arranged symmetrically with respect to the center line C passing through the center in the left-right direction, and the ends of the leg portions 251 and 252 are paired through the wall portion 201. Each of the holes 20c is penetrated.

図８および図９に示すように左右方向中央を通過する中心線Ｃを境界にして、一方ロック機構に含まれる一方ロック部材２４１は左側に配置され、他方ロック機構に含まれる他方ロック部材２４２は右側に配置され、両者２４１，２４２の形状は中央連結部材２０の中央を通過する仮想の中心面に関して左右対称形状かつ左右対称配置となる。そこで説明の重複を避けるため、以下、主に他方ロック部材２４２につき説明する。   As shown in FIGS. 8 and 9, with the center line C passing through the center in the left-right direction as a boundary, the one lock member 241 included in the one lock mechanism is disposed on the left side, and the other lock member 242 included in the other lock mechanism is Arranged on the right side, the shapes of both 241 and 242 are symmetrical with respect to a virtual center plane passing through the center of the central connecting member 20 and symmetrically arranged. In order to avoid duplication of explanation, the other lock member 242 will be mainly described below.

図９に示すように、他方ロック部材２４２は、１対の壁部２０１，２０２の間に介在する。そして、左右方向中央の中心線Ｃ上に合わせて円形断面の貫通孔２４４が形成される。貫通孔２４４は、同様に形成された一方ロック部材２４２の貫通孔２４３と整列し、これら貫通孔２４３，２４４を、共通する１本の連結ピン２７が貫通する。   As shown in FIG. 9, the other lock member 242 is interposed between the pair of wall portions 201 and 202. A through hole 244 having a circular cross section is formed on the center line C at the center in the left-right direction. The through hole 244 is aligned with the similarly formed through hole 243 of the one lock member 242, and a common connecting pin 27 passes through these through holes 243 and 244.

図９に示すように、壁部２０１，２０２には左右方向中央の中心線Ｃ上に１対の長孔２０ａが穿設される。図９に示す正面視において１対の長孔２０ａは同一形状、同一寸法、同一位置にあり、上下方向に延び、連結ピン２７の両端とそれぞれ係合する。これにより連結ピン２７は長孔２０ａに案内されて上下方向に移動可能である。なお長孔２０ａは連結ピン２７の延在方向と直角方向に延びることから、連結ピン２７は中心線Ｃに沿ってピン延在方向と直角に移動する。   As shown in FIG. 9, a pair of long holes 20a are formed in the walls 201 and 202 on the center line C at the center in the left-right direction. In the front view shown in FIG. 9, the pair of long holes 20 a have the same shape, the same size, and the same position, extend in the vertical direction, and engage with both ends of the connecting pin 27. Thereby, the connecting pin 27 is guided by the long hole 20a and can move in the vertical direction. Since the long hole 20a extends in a direction perpendicular to the extending direction of the connecting pin 27, the connecting pin 27 moves along the center line C at a right angle to the extending direction of the pin.

他方ロック部材２４２のうち中心線Ｃから最も遠い下端部には、断面円形の他方支持ピン２４６の中央領域が固定される。そして他方支持ピン２４６の両端が壁部２０１，２０２に向かってそれぞれ突出し、中心線Ｃよりも右側で壁部２０１，２０２にそれぞれ穿設されて左右方向に延びる１対の長孔２０ｂと係合する。図９に示す正面視において１対の長孔２０ｂは同一形状、同一寸法、同一位置にあるため、他方支持ピン２４６は右側の長孔２０ｂに案内されて左右方向に移動可能である。同様に壁部２０１，２０２のうち中心線Ｃよりも左側にも１対の長孔２０ｂが穿設される。また他方支持ピン２４６と同様に、一方ロック部材２４１に一方支持ピン２４５が固定され、一方支持ピン２４５は中心線Ｃよりも左側の長孔２０ｂに案内されて左右方向に移動可能である。   The center region of the other support pin 246 having a circular cross section is fixed to the lower end portion of the other lock member 242 farthest from the center line C. Then, both ends of the other support pin 246 protrude toward the wall portions 201 and 202, respectively, and engage with a pair of long holes 20b that are respectively drilled in the wall portions 201 and 202 on the right side of the center line C and extend in the left-right direction. To do. In the front view shown in FIG. 9, since the pair of long holes 20b have the same shape, the same size, and the same position, the other support pin 246 is guided by the right long hole 20b and can move in the left-right direction. Similarly, a pair of long holes 20b are also formed on the left side of the center line C in the walls 201 and 202. Similarly to the other support pin 246, the one support pin 245 is fixed to the one lock member 241, and the one support pin 245 is guided in the long hole 20b on the left side of the center line C and is movable in the left-right direction.

図１２に示すように、壁部２０１，２０２には中心線Ｃに沿って一対の長孔２０ａが穿設され、中心線Ｃに関し左右対称に二対の長孔２０ｂが穿設される。また壁部２０１には中心線Ｃに関し左右対称に配置された一対の貫通孔２０ｃが穿設される。この他に、壁部２０１，２０２には連結軸２６１が挿通固定される１対の貫通孔２６１ｈと、連結軸２６２が挿通固定される１対の貫通孔２６２ｈが穿設される。貫通孔２６１ｈと貫通孔２６２ｈは中心線Ｃに関し左右対称に配置される。   As shown in FIG. 12, a pair of long holes 20 a are formed along the center line C in the walls 201 and 202, and two pairs of long holes 20 b are formed symmetrically with respect to the center line C. The wall 201 is provided with a pair of through holes 20c that are arranged symmetrically with respect to the center line C. In addition, a pair of through holes 261h through which the connecting shaft 261 is inserted and fixed and a pair of through holes 262h through which the connecting shaft 262 is inserted and fixed are formed in the wall portions 201 and 202. The through hole 261h and the through hole 262h are arranged symmetrically with respect to the center line C.

他方ロック部材２４２のうち他方支持ピン２４６および連結ピン２７の双方から離れた位置には傾斜面２８２が形成される。傾斜面２８２は他方ロック部材２４２の上端部に配置されて連結ピン２７および他方支持ピン２４６の延在方向に対し傾斜し、図１０に示すように壁部２０１寄りに指向する。傾斜面２８２の傾斜は、最も壁部２０１寄りの部位で最も下側にあり、壁部２０２に近づくにつれて徐々に上方に向かう。   An inclined surface 282 is formed at a position away from both the other support pin 246 and the connecting pin 27 in the other lock member 242. The inclined surface 282 is disposed at the upper end of the other lock member 242, is inclined with respect to the extending direction of the connecting pin 27 and the other support pin 246, and is directed toward the wall 201 as shown in FIG. The slope of the inclined surface 282 is at the lowest side in the portion closest to the wall portion 201 and gradually moves upward as it approaches the wall portion 202.

傾斜面２８２は他方ロック部材２４２のうち壁部２０１寄りに形成される。これに対し他方ロック部材２４２のうち壁部２０２寄りには、連結ピン２７および他方支持ピン２４６の軸線と平行な面２８４が形成される。平行面２８４および傾斜面２８２は連結ピン２７および他方支持ピン２４６の軸線方向に連続して形成される。   The inclined surface 282 is formed closer to the wall 201 of the other lock member 242. On the other hand, a surface 284 parallel to the axis of the connecting pin 27 and the other support pin 246 is formed near the wall 202 of the other lock member 242. The parallel surface 284 and the inclined surface 282 are formed continuously in the axial direction of the connecting pin 27 and the other support pin 246.

また傾斜面２８２は、ボタン２５から突出して壁部２０２に向かって延びる脚部２５２の先端と近接する。脚部２５２の先端の下端側には、傾斜面２８２と対応するよう切り欠いて形成された脚部傾斜面２５２ｃが形成される。同様に一方ロック部材２４１には傾斜面２８１および平行面２８３が形成され、傾斜面２８１は脚部２５１の先端に形成された脚部傾斜面２５１ｃと近接する。   The inclined surface 282 is close to the tip of the leg 252 that protrudes from the button 25 and extends toward the wall 202. On the lower end side of the tip of the leg 252, a leg inclined surface 252 c formed by cutting out so as to correspond to the inclined surface 282 is formed. Similarly, an inclined surface 281 and a parallel surface 283 are formed on the one lock member 241, and the inclined surface 281 is close to the leg inclined surface 251 c formed at the tip of the leg 251.

他方ロック部材２４２のうち他方支持ピン２４６および連結ピン２７の双方から最も離れた位置には上向きに突出する係合突起２９２が形成される。係合突起２９２は他方ロック部材２４２の上縁のうち中心線Ｃから最も離れた位置、つまりパイプ１６２の近傍にある。そして図１１に示すように係合突起２９２の先端がパイプ１６２の外周面と対応する円弧状の凹曲面にされる。したがって係合突起２９２の先端形状は壁部２０１寄りの部位および壁部２０２寄りの部位が壁部２０１，２０２の中間の部位よりも上向きに突出する。   An engagement protrusion 292 that protrudes upward is formed at a position farthest from both the other support pin 246 and the connection pin 27 in the other lock member 242. The engaging protrusion 292 is located farthest from the center line C among the upper edges of the other locking member 242, that is, in the vicinity of the pipe 162. As shown in FIG. 11, the front end of the engagement protrusion 292 is formed into an arcuate concave curved surface corresponding to the outer peripheral surface of the pipe 162. Therefore, as for the tip shape of the engagement protrusion 292, the part near the wall part 201 and the part near the wall part 202 protrude upward from the intermediate part between the wall parts 201 and 202.

他方ロック部材２４２のロック位置で、連結ピン２７は長孔２０ａ上端にされ、他方支持ピン２４６は長孔２０ｂのうち中心線Ｃに近い方の端にされて、他方ロック部材２４２の係合突起２９２は、下方からパイプ１６２の外周面を係合支持する。これによりパイプ１６２は連結軸２６２回りの回動を不能にされる。   At the lock position of the other lock member 242, the connecting pin 27 is at the upper end of the long hole 20a, and the other support pin 246 is at the end of the long hole 20b closer to the center line C, and the engagement protrusion of the other lock member 242 292 engages and supports the outer peripheral surface of the pipe 162 from below. As a result, the pipe 162 cannot be rotated around the connecting shaft 262.

同様に一方ロック部材２４１の係合突起２９１は、下方からパイプ１６１の外周面を支持するように係合する。これによりパイプ１６１は連結軸２６１回りの相対回動を不能にされる。また図９に示す他方ロック部材２４２のロック位置で、連結ピン２７は長孔２０ａの上端に位置し、他方支持ピン２４６は長孔２０ｂのうち中心線Ｃに最も近い端に位置する。そして脚部２５２は壁部２０２から最も離れた位置にある。また図８および図１０に示す一方ロック部材２４１および他方ロック部材２４２のロック位置で、２個のロック部材２４１，２４２を同時に動作させる操作子であるボタン２５は、壁部２０１から最も離れた位置にされる。そして脚部傾斜面２５２ｃは傾斜面２８２のうち最も壁部２０１寄りの部位と接触する。   Similarly, the engagement protrusion 291 of the one lock member 241 is engaged so as to support the outer peripheral surface of the pipe 161 from below. This prevents the pipe 161 from rotating relative to the connecting shaft 261. 9, the connecting pin 27 is positioned at the upper end of the long hole 20a, and the other support pin 246 is positioned at the end closest to the center line C of the long hole 20b. The leg portion 252 is located farthest from the wall portion 202. 8 and 10, the button 25, which is an operator that simultaneously operates the two lock members 241 and 242, at the lock position of the one lock member 241 and the other lock member 242, is the position farthest from the wall portion 201. To be. The leg inclined surface 252c is in contact with a portion of the inclined surface 282 closest to the wall 201.

これまで説明したように、一方ロック部材２４１および他方ロック部材２４２は、中央連結部材２０にそれぞれ支持されて、図８〜図１１に示すようにパイプ１６１，１６２の回動を不能にするロック位置にされる。また一方ロック部材２４１および他方ロック部材２４２は、図１３〜図１５に示すようにパイプ１６１，１６２の回動を許容するフリー位置に選択的にされる。   As described so far, the one lock member 241 and the other lock member 242 are respectively supported by the central connecting member 20, and as shown in FIGS. 8 to 11, are locked positions where the rotation of the pipes 161 and 162 is disabled. To be. Further, the one lock member 241 and the other lock member 242 are selectively set to a free position that allows the pipes 161 and 162 to rotate as shown in FIGS.

図１３はロック解除された横材の中央部を取り出して示す平面図であり、中央連結部材２０を断面にして表す。図１４はロック解除された横材の中央部を取り出して示す正面図であり、紙面右側は一部断面で表される。図１５は図１３のＸＩＶ−ＸＩＶにおける断面を示す説明図である。   FIG. 13 is a plan view showing the central part of the cross member that has been unlocked, and shows the central connecting member 20 in cross section. FIG. 14 is a front view showing the central part of the unlocked cross member taken out, and the right side of the drawing is partially shown in cross section. FIG. 15 is an explanatory view showing a cross section taken along line XIV-XIV in FIG.

ボタン２５が前述した図８、図１０、および図１１に示すように壁部２０１から離隔した原位置にあるとき、脚部２５１の先端は傾斜面２８１の最も壁部２０１寄りの部位と接触するとともに、脚部２５２の先端は傾斜面２８２の最も壁部２０１寄りの部位と接触する。   When the button 25 is in the original position separated from the wall 201 as shown in FIGS. 8, 10, and 11, the tip of the leg 251 contacts the portion of the inclined surface 281 closest to the wall 201. At the same time, the tip of the leg 252 contacts the portion of the inclined surface 282 closest to the wall 201.

２個のロック部材２４１，２４２を同時に動作させる共通の操作子であるボタン２５はセンター孔３０ｈ内を摺動可能であり、壁部２０１の垂直方向に移動することができる。ボタン２５を押し込むと、ボタン２５は壁部２０１に当接するまで前進し、１対の脚部２５１，２５２を介して一方ロック部材２４１および他方ロック部材２４２を同時にロック位置からフリー位置にする。図１３〜図１５はこれらロック部材２４１，２４２のフリー位置を示す。一方ロック部材２４１はフリー位置で中央連結部材２０に対するパイプ１６１の回動を許容する。他方ロック部材２４２もフリー位置で中央連結部材２０に対するパイプ１６２の回動を許容する。   A button 25 that is a common operator for operating the two lock members 241 and 242 simultaneously is slidable in the center hole 30 h and can move in the vertical direction of the wall 201. When the button 25 is pushed in, the button 25 moves forward until it comes into contact with the wall portion 201, and the one lock member 241 and the other lock member 242 are simultaneously moved from the lock position to the free position via the pair of leg portions 251 and 252. 13 to 15 show the free positions of these lock members 241 and 242. On the other hand, the lock member 241 allows the pipe 161 to rotate with respect to the central connecting member 20 in the free position. On the other hand, the lock member 242 also allows the pipe 162 to rotate with respect to the central connecting member 20 in the free position.

具体的には、ボタン２５が押し込み操作されて壁部２０１に向かって前進すると、脚部２５１，２５２がピン２４５，２４６，２７の軸線方向に前進して傾斜面２８１，２８２をそれぞれ同時に押し込む。そうすると押し込み力を受けてロック部材２４１，２４２は下方へ移動する。このとき連結ピン２７は長孔２０ａに沿って下方へ移動し、支持ピン２４５，２４６は長孔２０ｂに沿って中央線Ｃから離れる方向へ移動する。これによりロック部材２４１，２４２は移動して姿勢を変える。   Specifically, when the button 25 is pushed and advanced toward the wall 201, the legs 251 and 252 advance in the axial direction of the pins 245, 246 and 27 and simultaneously push the inclined surfaces 281 and 282, respectively. Then, the lock members 241 and 242 move downward by receiving the pushing force. At this time, the connecting pin 27 moves downward along the long hole 20a, and the support pins 245 and 246 move away from the center line C along the long hole 20b. As a result, the lock members 241 and 242 move and change their postures.

ボタン２５が壁部２０１に隣接する操作位置まで前進すると、脚部２５１，２５２は傾斜面２８１，２８２をそれぞれ下方へ押し退け、脚部２５１，２５２の先端が壁部２０２に達する。これによりロック部材２４２は図１３〜図１５に示すフリー位置にされ、ロック部材２４１も中心線Ｃに関して左右対称な姿勢でフリー位置にされる。かくしてボタン２５は、原位置から操作位置に操作されることにより一方ロック部材２４１および他方ロック部材２４２をロック位置からフリー位置に動作させる。   When the button 25 moves forward to the operation position adjacent to the wall portion 201, the leg portions 251 and 252 push the inclined surfaces 281 and 282 downward, and the tips of the leg portions 251 and 252 reach the wall portion 202. As a result, the lock member 242 is set to the free position shown in FIGS. 13 to 15, and the lock member 241 is also set to the free position in a symmetrical manner with respect to the center line C. Thus, the button 25 moves the one lock member 241 and the other lock member 242 from the lock position to the free position by being operated from the original position to the operation position.

他方ロック部材２４２のフリー位置で、連結ピン２７は長孔２０ａ下端にされ、他方支持ピン２４６は長孔２０ｂのうち中心線Ｃから遠い方の端にされて、係合突起２９２がパイプ１６２から離れて中心線Ｃに近づくように引き込まれる。これによりパイプ１６２は連結軸２６２回りに回動自在にされる。   At the free position of the other lock member 242, the connecting pin 27 is at the lower end of the long hole 20a, the other support pin 246 is at the end of the long hole 20b far from the center line C, and the engaging protrusion 292 is removed from the pipe 162. It is drawn away so as to approach the center line C. As a result, the pipe 162 is rotatable about the connecting shaft 262.

同様に一方ロック部材２４１の係合突起２９１は、パイプ１６１から離れて中心線Ｃに近づくように引き込まれる。これによりパイプ１６１は連結軸２６１回りに回動自在にされる。   Similarly, the engagement protrusion 291 of the one lock member 241 is pulled away from the pipe 161 so as to approach the center line C. As a result, the pipe 161 is rotatable around the connecting shaft 261.

図１５に示すように、他方ロック部材２４２のフリー位置で、脚部２５２は傾斜面２８２と接触しない。そして脚部２５２は平行面２８４と平行に延び、平行面２８４における壁部２０１側から壁部２０２側まで連続して接触する。したがって、他方ロック部材２４２が何らかの力を受けて脚部２５２を上方へ押す場合であっても、脚部２５２は他方ロック部材２４２によって動かされることはなく、他方ロック部材２４２のフリー位置を保持する。同様に脚部２５１は一方ロック部材２４１のフリー位置を保持する。これによりボタン２５はロック解除を保持する。   As shown in FIG. 15, the leg 252 does not contact the inclined surface 282 at the free position of the other lock member 242. The leg portion 252 extends in parallel with the parallel surface 284 and continuously contacts from the wall 201 side to the wall 202 side of the parallel surface 284. Accordingly, even when the other lock member 242 receives some force and pushes the leg 252 upward, the leg 252 is not moved by the other lock member 242 and maintains the free position of the other lock member 242. . Similarly, the leg portion 251 holds the free position of the one lock member 241. Thereby, the button 25 holds unlocking.

なお、ロック動作機構は操作子であるボタン２５を原位置に復帰させるリターンスプリングをさらに含んでもよい。かかるリターンスプリングは壁部２０１とボタン２５との間に介挿されて、ボタン２５を壁部２０１から離れるよう付勢する。   Note that the lock operation mechanism may further include a return spring for returning the button 25 as an operator to the original position. The return spring is inserted between the wall part 201 and the button 25 to urge the button 25 away from the wall part 201.

ところで本実施例においては、横材１６が長手方向一方に延びるパイプ１６１と、長手方向他方に延びるパイプ１６２と、長手方向中央部にあってこれらパイプ１６１およびパイプ１６２と回動可能に連結する中央連結部材２０と、パイプ１６１と中央連結部材２０を回動不能にする一方ロック機構としての一方ロック部材２４１と、パイプ１６２と中央連結部材２０を回動不能にする他方ロック機構としての他方ロック部材２４２と、これら双方のロック機構を同時に解除して双方のロック解除を保持するロック動作機構としてのボタン２５を有する。また横材１５Ｌ，１５Ｒも同様に構成される。   By the way, in the present embodiment, the cross member 16 has a pipe 161 extending in one longitudinal direction, a pipe 162 extending in the other longitudinal direction, and a center that is pivotally connected to the pipe 161 and the pipe 162 in the central portion in the longitudinal direction. The connecting member 20, the one lock member 241 as one lock mechanism that disables rotation of the pipe 161 and the central connecting member 20, and the other lock member as other lock mechanism that disables rotation of the pipe 162 and the central connecting member 20. 242 and a button 25 serving as a lock operation mechanism that simultaneously releases both of these lock mechanisms and holds both locks released. Also, the cross members 15L and 15R are configured similarly.

これにより、プレイヤード１０を折り畳む際に乳幼児の保護者がロック動作機構を操作すると、一方ロック機構も他方ロック機構も確実にロック解除される。この結果、プレイヤードの折り畳み作業中に、一方のパイプ１６１が回動自在にされるが他方のパイプ１６２が回動不能のままであり、折り畳み作業が煩雑になるという不都合が解消される。したがって保護者はプレイヤード１０の折り畳み操作を容易に行うことができる。   Thus, when the infant guardian operates the lock operation mechanism when folding the playard 10, both the one lock mechanism and the other lock mechanism are reliably unlocked. As a result, the inconvenience that one pipe 161 is made rotatable during the folding operation of the playerd but the other pipe 162 remains unrotatable, and the folding work becomes complicated. Therefore, the guardian can easily perform the folding operation of the playerd 10.

また本実施例によれば、ロック動作機構として、一方ロック部材２４１および他方ロック部材２４２を同時にロック位置からフリー位置にする共通の操作子としてのボタン２５を含むことから、簡易なボタン操作によって、２個のロック部材２４１，２４２は確実にロック解除される。したがってロック動作機構を好適に実現することができる。   In addition, according to the present embodiment, the lock operation mechanism includes the button 25 as a common operator for simultaneously moving the one lock member 241 and the other lock member 242 from the lock position to the free position. The two lock members 241 and 242 are reliably unlocked. Therefore, the lock operation mechanism can be preferably realized.

また操作子としてのボタン２５が原位置から操作位置に操作されることにより一方ロック部材２４１および他方ロック部材２４２をロック位置からフリー位置に動作させる本実施例によれば、ロック動作機構はボタン２５を原位置に復帰させるリターンスプリングをさらに含んでもよい。この結果、ボタン２５を押し込まない限り、ロック部材２４１，２４２がロック位置にされる、したがって、パイプ１６１，１６２のロックが不用意に解除されることがない。   Further, according to the present embodiment in which the one lock member 241 and the other lock member 242 are moved from the lock position to the free position by operating the button 25 as the operation element from the original position to the operation position, the lock operation mechanism is the button 25. It may further include a return spring that returns the to the original position. As a result, unless the button 25 is pushed, the lock members 241 and 242 are brought into the lock position, and therefore the pipes 161 and 162 are not inadvertently released.

また本実施例によれば、一方ロック部材２４１および他方ロック部材２４２は、貫通孔２４３，２４４がそれぞれ形成され、これらの貫通孔２４３，２４４を共通する１本の連結ピン２７が貫通し、中央連結部材２０は連結ピン２７の両端と係合する中央案内部として長孔２０ａが形成され、連結ピン２７は長孔２０ａに沿って移動する。これにより、一方ロック部材２４１および他方ロック部材２４２がピン２７で連結されて連動することができる。したがってロック動作機構として、双方のロック機構を同時に解除する構造を好適に実現することが可能になる。   Further, according to the present embodiment, the one lock member 241 and the other lock member 242 are formed with through holes 243 and 244, respectively, and one common connecting pin 27 passes through these through holes 243 and 244, and the center The connecting member 20 is formed with a long hole 20a as a central guide portion that engages with both ends of the connecting pin 27, and the connecting pin 27 moves along the long hole 20a. As a result, the one lock member 241 and the other lock member 242 can be linked and interlocked by the pin 27. Therefore, it is possible to preferably realize a structure that simultaneously releases both lock mechanisms as the lock operation mechanism.

また本実施例によれば、一方ロック部材２４１は中央連結部材２０の左方に配置され、他方ロック部材２４２は中央連結部材２０の右方に配置され、中央連結部材２０の中央を通過する仮想の中心面（中心線Ｃ）に関してこれら一方ロック部材２４１および他方ロック部材２４２は対称形状かつ対称配置され、連結ピン２７は中心線Ｃに沿ってピン延在方向と直角に上下移動する。これにより、双方のロック部材２４１，２４２が中心線Ｃに関して対称に挙動し、双方のロック部材２４１，２４２を同時に解除する構造を好適に実現することが可能になる。   Further, according to the present embodiment, the one lock member 241 is disposed on the left side of the central coupling member 20, and the other lock member 242 is disposed on the right side of the central coupling member 20 and passes through the center of the central coupling member 20. The one lock member 241 and the other lock member 242 are symmetrically arranged with respect to the center plane (center line C), and the connecting pin 27 moves vertically along the center line C at right angles to the pin extending direction. Thereby, both the locking members 241 and 242 behave symmetrically with respect to the center line C, and it is possible to suitably realize a structure in which both the locking members 241 and 242 are simultaneously released.

また本実施例によれば、一方ロック部材２４１は連結ピン２７と平行に延びる一方支持ピン２４５および一方支持ピン２４５の延在方向に対して傾斜する傾斜面２８１が設けられる。同様に他方ロック部材２４２は連結ピン２７と平行に延びる他方支持ピン２４６および他方支持ピン２４６の延在方向に対して傾斜する傾斜面２８２が設けられる。中央連結部材２０は中心面（中心線Ｃ）に関し左方および右方に対称配置される対称形状の左方案内部および右方案内部になる長孔２０ｂが形成される。左方の長孔２０ｂは一方支持ピン２４５の両端と係合して、一方支持ピン２４５をピン延在方向と直角に案内し、右方の長孔２０ｂは他方支持ピン２４６の両端と係合して、他方支持ピン２４６をピン延在方向と直角に案内する。ボタン２５は傾斜面２８１，２８２にそれぞれ当接する１対の脚部２５１，２５２を有し、ボタン２５が操作されることにより、脚部２５１，２５２が支持ピン２４５，２４６の延在方向に前進して傾斜面２８１，２８２を同時に押し込み一方ロック部材２４１および他方ロック部材２４２を動かす。   Further, according to the present embodiment, the one lock member 241 is provided with the one support pin 245 extending in parallel with the connecting pin 27 and the inclined surface 281 inclined with respect to the extending direction of the one support pin 245. Similarly, the other lock member 242 is provided with the other support pin 246 extending in parallel with the connecting pin 27 and an inclined surface 282 inclined with respect to the extending direction of the other support pin 246. The central connecting member 20 is formed with an elongated hole 20b that is symmetrically arranged on the left and right sides with respect to the center plane (center line C) and becomes a left guide portion and a right guide portion. The left elongated hole 20b engages with both ends of one support pin 245, guides one support pin 245 at right angles to the pin extending direction, and the right elongated hole 20b engages with both ends of the other support pin 246. Then, the other support pin 246 is guided at right angles to the pin extending direction. The button 25 has a pair of leg portions 251 and 252 that abut against the inclined surfaces 281 and 282, respectively, and when the button 25 is operated, the leg portions 251 and 252 advance in the extending direction of the support pins 245 and 246. Then, the inclined surfaces 281 and 282 are simultaneously pushed, and the one lock member 241 and the other lock member 242 are moved.

これにより、双方のロック部材２４１，２４２が中心面（中心線Ｃ）に関して対称に挙動することから、双方のロック機構を同時に解除する構造を好適に実現することが可能になる。しかもボタンの脚部が支持ピン２４５，２４６の延在方向に前進して一方ロック部材の傾斜面２８１および他方ロック部材の傾斜面２８２を同時に押し込む。したがって、ボタン２５のピン延在方向の前進をロック部材２４１，２４２のピン直角方向の動きに変換することが可能となることから、ボタン２５の操作によって確実にロックを解除することができる。   Thereby, since both the locking members 241 and 242 behave symmetrically with respect to the center plane (center line C), it is possible to suitably realize a structure for simultaneously releasing both the locking mechanisms. Moreover, the leg portion of the button advances in the extending direction of the support pins 245 and 246 and simultaneously pushes the inclined surface 281 of the one lock member and the inclined surface 282 of the other lock member. Accordingly, since the advancement of the button 25 in the pin extending direction can be converted into the movement of the lock members 241 and 242 in the direction perpendicular to the pin, the lock can be reliably released by the operation of the button 25.

また本実施例によれば、一方ロック部材２４１および他方ロック部材２４２は、傾斜面２８１，２８２に隣接して連結ピン２７と平行な面２８３，２８４がそれぞれ設けられ、傾斜面２８１，２８２を押し込んだ脚部２５１，２５２は、さらに前進しこれらの平行面２８３，２８４と平行に延びて接触する。これにより、ロック部材２４１，２４２が何らかの力を受けて脚部２５１，２５２を上方へ押す場合であっても、脚部２５１，２５２はロック部材２４１，２４２によって動かされることはなく、ロック部材２４１，２４２のフリー位置を保持することができる。   Further, according to the present embodiment, the one lock member 241 and the other lock member 242 are provided with the surfaces 283 and 284 parallel to the connecting pin 27 adjacent to the inclined surfaces 281 and 282, respectively, and the inclined surfaces 281 and 282 are pushed in. The legs 251 and 252 further advance and extend in parallel with and contact the parallel surfaces 283 and 284. Accordingly, even when the lock members 241 and 242 receive some force and push the leg portions 251 and 252 upward, the leg portions 251 and 252 are not moved by the lock members 241 and 242, and the lock member 241 is not moved. , 242 can be held.
