  The present invention relates to a bed for a crib.

  For example, Japanese Patent Application Laid-Open No. 2008-154752 (Patent Document 1) is known as a baby bed that is provided with a foldable frame, is light in weight so as to be portable, and is compactly folded when not in use. In Patent Document 1, a flat bed plate is detachably suspended from an upper horizontal frame of a frame, a short hollow cylindrical protective cover is placed on the bed plate, and an infant is laid inside the protective cover. Is described.

JP 2008-154752 A

  However, the baby bed of Patent Document 1 has the following problems. That is, since the flat bed plate is a huge single flat plate, even if the frame can be folded compactly, the bed plate takes up space when not in use.

  Moreover, in the crib of patent document 1, although the protective cover which can enclose an infant is prepared, a protective cover is a three-dimensional shape and takes a certain amount of space when not in use. Then it will get in the way when not in use. However, if the protective cover is made of a material having excellent flexibility so that it can be folded, the protective cover cannot maintain a three-dimensional shape, causing undesired deformation or deterioration of durability.

  It is a first object of the present invention to provide a crib bed that is flush when in use and can be folded when not in use. In addition, a second object of the present invention is to provide a technique capable of safely laying an infant without using a protective cover as in Patent Document 1.

For this purpose, the crib according to the present invention is removed from the bottom surface of the bottom plate so that a plurality of plate pieces and a bottom plate having a bendable deformable bending line connecting the plate pieces and the central region intersects with the bending line of the bottom plate. A bar member that can be attached and a wall plate that rises 15 cm or more from the upper surface of the floor plate and surrounds the upper surface of the floor plate.

  The floor plate is rectangular, and the first side to the fourth side corresponding to the four sides of the rectangle are contour lines, and among these, the first side and the second side extend parallel to each other, and among these, the third side and the second side The four sides extend orthogonally to the first side and the second side, and the bending line of the base plate extends parallel to the first side and the second side, and the third side and the fourth side are cloth or soft that extends parallel to the side Each of the sheet-like cylindrical members is fixed. The bar member extends in parallel with the third side and the fourth side of the floor plate.

  The wall plate is a first wall plate which is a plate piece attached to the floor plate as a boundary line that can be folded and deformed at the first side of the floor plate, and a plate piece that is attached to the floor plate as a boundary line that can be folded and deformed at the second side of the floor plate A second wall plate, a third wall plate removably inserted through the third side cylindrical member, and a fourth wall plate removably inserted through the fourth side cylindrical member.

  According to the present invention, at the time of use, it is preferable to spread the floor plate flush. The floor plate spread out flush with the surface is stably supported by the bar member so that it cannot be bent and deformed. Further, when not in use, the bed can be folded, so that the bed of the crib can be saved. Moreover, since the wall board is provided, the infant sleeping on the laying board spread out on the same plane can be surrounded by the wall board, and the infant can be laid down safely.

  Moreover, according to this invention, a base plate can be stably supported with a rod member so that a rectangular base plate may not bend and deform | transform. The third side and the fourth side may be rectangular short sides, but are preferably long rectangular sides.

  The wallboard is not limited to one embodiment. The wall board may be provided so as to rise from the floor board and hang down. ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to comprise a base plate and a wall board in one box-shaped body, and can improve the intensity | strength of a base plate. Moreover, the floor plate and the wall plate can form a five-sided box-like body having no upper surface, and can suitably support and accommodate infants.

  The first wall plate of the present invention connects the first side of the floor plate to the floor plate as a boundary line that can be folded and deformed, and the second wall plate connects the second side of the floor plate to the floor plate as a boundary line that can be folded and deformed. According to the present invention, since the floor board and the wall board are continuous, the folding operation and the assembling operation of the crib can be performed smoothly. The mounting structure between the wall plate and the floor plate is not particularly limited, such as a button, a tape, a hook-and-loop fastener, a slide fastener, and a bracket. Further, according to the present invention, the cylindrical members on the third side and the fourth side can be easily folded following the bending line of the floor plate in a state where the wall plate is not inserted. Therefore, the floorboard can be easily folded. In addition, since the third and fourth wall boards are connected to the floor board perpendicular to the bending line when the crib is in use, it is possible to further prevent the floor board from being bent.

As one embodiment of the present invention, the cylindrical member on the third side is fixed to the first wall plate and the second wall plate at both ends, respectively. As another embodiment of the present invention, the cylindrical member on the fourth side is fixed to the first wall plate and the second wall plate at both ends, respectively. According to this embodiment, both ends of the tubular member are fixed to the first wall plate and the second wall plate, respectively. Therefore, the floor plate and the wall plate can form a five-sided box-like body having no upper surface, and can support and accommodate infants suitably.

  Although the support structure for supporting the floor plate flush is not particularly limited, as a preferred embodiment, the floor plate has a cylindrical member made of a cloth or a soft sheet that is fixed to the lower surface and through which a bar member is inserted. According to this embodiment, since the floorboard is supported flush, the infant can be supported stably. In addition, when the rod member is removed and the laying plate is folded, the tubular member is bent and deformed following the bending line, so that the laying plate can be folded without hindrance.

  Thus, according to this invention, it can be used conveniently also as a bed which makes an infant sleep.

  Hereinafter, embodiments of the present invention will be described in detail based on examples shown in the drawings.

  FIGS. 1-6 is one Example of this invention, Comprising: The whole outline of the playard which can be used also as a crib is shown. Of these, FIGS. 1 to 5 show the use state in which the playard is unfolded, and FIG. 6 shows 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.

  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.

  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 can be folded, and a plurality of frames are disposed along the periphery of the infant accommodation space. Column material 14 and a plurality of cross members 15L, 15R, and 16 that connect adjacent column materials to each other. Specifically, the frame structure 11 includes four pillar members 14 extending in the vertical direction, a pair of cross members 15L and 15R provided on both sides of the playard, and a pair of both ends of the playard. The cross members 16 and 16 and the cross pipe 17 arrange | positioned so that it may become a diagonal line in planar view are included. In plan view, the plurality of column members 14 are arranged on the outer periphery of the frame structure 11, and the cross members 15L, 15R, 16 connect the adjacent column members 14, 14 to each other.

  The infant storage space is rectangular in plan view, and the column members 14 are arranged to stand upright at the corners of the four corners of the rectangle in plan view. A cross member 16 constituting a short side of a rectangle is installed between the two column members 14 and 14 arranged at one end of the playard. Similarly, the cross member 16 which comprises the rectangular short side is constructed also between the two pillar materials 14 and 14 arrange | positioned at a playerd other end part. Similarly, a cross member 15R constituting a long side of a rectangle is installed between the 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. Moreover, the cross members 16 and 15R are comprised by the center connection member 20 provided in the center part, the pipe extended from the center connection member 20 to a longitudinal direction one side, and the pipe extended from the center connection member 20 to a longitudinal direction other side.

  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 playerd 10 is folded, the two pipes 161 and 162 extend upward from the central connecting member 20, respectively, 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. As shown in FIG. 6, the two pipes extend upward from the central connecting member 20, and the cross member 15 </ b> R has a V shape.

  Similarly, the cross member 15L constituting the long side of the rectangle is provided with the central connecting member 20 and extends in a straight line when the playerd is used. However, in the folded state of playard, it folds and deforms in the center. Therefore, when the playerd 10 is folded, the two pipes extend upward from the central connecting member 20, and the cross member 15L is formed in a V shape.

  Of the plurality of cross members, only the cross member 15L is rotatably and slidably connected to the column member 14 via the slide member 18 at two places on the other side of the playerd. 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 other 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.

  When the fastener 19 is pulled out and the pair of slide members 18 are slidable, the cross member 15L moves downward together with the pair of slide members 18, and can be brought to a position indicated by a two-dot chain line in FIG. 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.

  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 cross section in FIGS. 2, 3, and 5. 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. For this reason, as shown in FIGS. 2 and 3, the cross pipe 17 can be maintained in an X-shaped state when the playerd is used. Further, as shown in FIG. 6, 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.

  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.

  However, when the playerd 10 is not used, when one end of the playerd 10 is lifted as shown in FIGS. 5 and 6, the wheel cover protrusion 22 s moves away from the installation floor surface S and the wheel 21 moves to the installation floor surface S. Ground. 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.

  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.

  Next, the cloth-like member 12 will be described. The cloth-like member 12 is made of a material such as a mesh having a size of about 0.5 to 5 mm, a finer net, or a cloth, and is formed of four pillar members 14. Are stretched on each of the four surfaces. Alternatively, the cloth-like member 12 may be a material other than cloth, for example, a vinyl sheet having a certain degree of transparency. 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. Accordingly, the cloth-like member 12 reliably surrounds the floor plate 41 provided above the cross pipe 17.

  Next, the rod member 13 will be described. The rod member 13 is a pair of straight rod-like bodies extending linearly on both sides of the playard, and is formed of a hard material so as not to be bent by the weight of the infant, and has a horizontal posture. The 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.

  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 14 and is fixed slightly above the cross pipe 17. The bracket 32 is fixed to the central portion of the column member 14. The brackets 31 and 32 support the end of the bar member 13. The rigid bar member 13 is a pipe having sufficient bending strength and shear strength so that it can withstand the impact load when the infant actively moves in addition to the weight of the infant, 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. In order to facilitate understanding of the drawings, in FIG. 2 and FIG. 5, a cylindrical member 42 described later surrounding the outer periphery of the rod-shaped body 13 is omitted.

  FIG. 7 is a diagram showing a cross-section taken along the line VII-VII in FIG. 2 in the direction of the arrow. The column 14, the bracket 32 fixed to the column, the bar member 13, and the bar member are fixed. The engaging member 37 is represented. Moreover, in order to represent the positional relationship of planar view, the floor board 41 and wall board supported by the rod member 13 are shown with a dashed-two dotted line.

  The brackets 32 attached and fixed to the four corners of the playard 10 engage with engaging members 37 fixed to the end portions of the bar members 13. The bracket 32 and the engaging member 37 will be described in detail with reference to FIG. 8. When the bracket 32 is viewed from the column material to which the bracket 32 is fixed, one adjacent column material is oriented in the 0 degree direction. The slit 33 opened in the 45 degree direction and the wide concave part 34 formed in the back of the slit 33 are formed with the other adjacent pillars as 90 degrees. The width of the recess 34 is wider than the opening width of the slit 33. The slit 33 extends in the vertical direction, and has an upper end opened and a lower end closed. Similarly, the recess 34 also extends in the vertical direction, with the upper end opened and the lower end closed.

  The engaging member 37 has a protrusion 38 that is oriented in a direction of 135 degrees with respect to the extending direction of the bar member 13 in the horizontal plane including the bar member 13. Grooves 39 extending in the vertical direction are formed on both sides at the base of the protrusion 38. For this reason, the protrusion 38 has a T-shaped cross section as shown in FIG.

  The slits 33 and the recesses 34 of the bracket 32 are engaged portions, the protrusions 38 of the engaging members 37 are engagement portions, and the protrusions 38 are inserted from the upper ends of the slits 33 and the recesses 34 so that they are engaged with each other. In this case, the engaging member 37 cannot be moved in the horizontal direction. The engaging member 37 is supported by the bracket 32. Further, the engagement member 37 is lifted upward, so that the engagement with the slit 33 and the recess 34 is released. Thus, the bar member 13 is detachably attached to the frame structure 11.

  The bracket 31 located at a position relatively lower than the bracket 32 is also configured in common with the bracket 32 described above. The engaging member 37 is detachably attached to the bracket 32 at a relatively high position, and is also detachably attached to the bracket 31 at a relatively low position. Thus, the pair of rod members 13 are selectively attached to a relatively high position and a relatively low position.

  Next, the floor plate 41 will be described. Since the bottom plate 41 of the present embodiment is a rectangular shape in plan view that forms the bottom surface of the infant storage space having a rectangular shape in plan view, for convenience of the outline of the bottom plate 41, the pair of long side portions are defined as the third side, the fourth side, It is called one side edge, the other side edge, or both side edges. A pair of short sides is referred to as a first side, a second side, one end, the other end, or both ends.

  As shown in FIG. 4, the floor plate 41 has an elongated cylindrical member 42 having openings at both ends. The cylindrical member 42 is made of cloth, and is attached to the lower surface of the floor plate 41 at both side edges. The rod member 13 is inserted through the pair of left and right tubular members 42, and both ends of the rod member 13 protrude from the tubular member 42.

  The floor board 41 includes a hard board piece having sufficient bending strength as a core material so as not to be deformed by the weight of the infant, and is formed of a material whose surface is relatively soft. Further, as shown in FIG. 7, the floor plate 41 is formed with three bent lines 43 extending in the played short side direction at equal intervals. The floor plate 41 can be bent and deformed at these bending lines 43, and is formed into a square cylinder when the playerd is folded, and surrounds the folded frame structure 11 as shown in FIG. In addition, the floor plate 41 formed into a square tube bundles the folded frame structure 11 and the wall plates 53 and 54 connected to both side edges of the floor plate 41 and a pair of rod members 13.

  In the state where the floor plate 41 is unfolded and stretched flat and the bar member 13 is attached to the lower surface of the floor plate 41, the central region of the hard bar member 13 intersects the three bent lines 43 substantially orthogonally as shown in FIG. Then, the floor plate 41 is supported.

  FIG. 9 is an exploded perspective view showing the floor plate 41 and the wall plate. The floor plate 41 is formed by connecting four plate pieces extending in the short side direction in the long side direction. The plate piece is, for example, a hard plastic or a light metal plate having rigidity, and both surfaces are covered with a cloth-like member or a film sheet. Adjacent plate pieces are connected via a bend line 43. The bending line 43 is formed of a cloth-like member or a film sheet. A cylindrical member 42 and cylindrical members 56 and 57 described later are attached and fixed to the surface of the floor plate 41 by sticking, sewing, or heat welding. The floor plate 41 has a first wall plate 51 extending at one end of the playerd and a second wall plate 52 extending at the other end of the playerd. The first wall plate 51 and the second wall plate 52 also include a hard plate piece having the same strength as the floor plate 41 as a core material, and is formed of a material having a relatively soft surface. That is, the first wall plate 51, the floor plate 41, and the second wall plate 52 are one member.

  A boundary line 55 between the floor plate 41 and the first wall plate 51 is a bent line, and the first wall plate 51 is bent and deformed by 90 degrees at the boundary line 55 as shown in FIG. The boundary line 55 between the floor plate 41 and the second wall plate 52 is also a bending line, and the second wall plate 52 also rises from the floor plate 41.

  As shown in FIG. 9, cylindrical members 56 and 57 having openings at both ends are attached and fixed to both side edges of the floor plate 41. One end openings 58 of the cylindrical members 56 and 57 are attached and fixed to the first wall plate 51, and the other end openings 59 of the cylindrical members 56 and 57 are attached and fixed to the second wall plate 52. The tubular member 56 is attached and fixed along one side edge of the floor plate 41, and the cylindrical member 57 is attached and fixed along the other side edge of the floor plate 41.

  The cylindrical members 56 and 57 are made of cloth, and are folded along the upper surface of the floor board 41 by lowering the first wall board 51 on the floor board 41 and lowering the second wall board 52 on the floor board 41. As shown in FIG. 9, the first wall plate 51 is raised at an angle of 90 degrees with respect to the floor plate 41 and the second wall plate 52 is raised at an angle of 90 degrees with respect to the floor plate 41, thereby The cylindrical members 56 and 57 also rise, and the four sides of the floor plate 41 are surrounded by the wall plates 51 and 52 and the cylindrical members 56 and 57.

  As shown by an arrow in FIG. 9, the third wall plate 53 can be inserted into the cylindrical member 56 from the other end opening 59, and the fourth wall plate 54 is inserted into the cylindrical member 57 from the other end opening 59. It can be inserted. The third wall plate 53 is inserted into the cylindrical member 56, and the fourth wall plate 54 is inserted into the cylindrical member 57, whereby the four wall plates 51 to 54 rise from the floor plate 41 and surround the four sides. To do. The rising height of the four wall plates 51 to 54 is 15 cm or more from the upper surface of the floor plate 41. Thereby, even if an infant comforter is laid on the floor board 41 and the infant is laid on the infant comforter, the concern that the infant's head is caught in the gap between the wall boards 51 to 54 and the infant comforter is eliminated. The

  The floor plate 41 and the wall plates 51 to 54 constitute a box-shaped body 61. The first wall plate 51 extends from one side edge of the floor plate 41 to the other side edge, and the second wall plate 52 also extends from one side edge of the floor plate 41 to the other side edge. The third wall plate 53 extends from one end portion of the floor plate 41 to the other end portion, and the fourth wall plate 54 also extends from one end portion of the floor plate 41 to the other end portion. Therefore, in the assembled box-shaped body 61, each wall board rises up with an almost no gap with an adjacent wall board.

  When assembling the playard 10, the floor plate 41 is unfolded, a pair of rod members 13 are passed through the cylindrical members 42 on the bottom surface of the floor plate, and the wall plates 53 and 54 are passed through the one end opening 58 or the other end opening 59. The box-shaped body 61 is formed by insertion. Further, the frame structure 11 is expanded, the box-shaped body 61 is inserted from above the expanded frame structure 11, and the end of the bar member 13 is attached to the bracket 31 or the bracket 32 of the frame structure 11. As a result, the playard 10 is put into use.

  The top surface of the floor board 41 provides a place for infants to play and sleep. Particularly in this embodiment, the guardian can select the bracket 31 or the bracket 32 and attach the bar member. Thus, by selectively changing the height position of the floor board 41, it can be used as a playard and a crib.

  As shown by a two-dot chain line in FIG. 2, the end of the bar member 13 is engaged with a relatively low bracket 31 to set the floor plate 41 at a relatively low first position. By attaching the floor plate 41 to the lower part of the frame structure 11 in this way, the cloth-like member 12 stands up to the upper part of the frame structure 11 and can be suitably used as a frame enclosure (played) for playing infants.

  As shown by a solid line in FIG. 2, the end of the bar member 13 is engaged with a relatively high bracket 32 to set the floor plate 41 at a relatively high second position. By attaching the floor plate 41 to the intermediate portion in the vertical direction of the frame structure 11 in this way, the floor plate 41 is closer to the upper part of the frame structure 11 than in the case of the above-mentioned playard, and is suitable as a bed (baby bed) for sleeping an infant. Can be used.

  When the playerd 10 is folded, the box-shaped body 61 is taken out from the frame structure 11 and disassembled in the reverse procedure to that described above, and the frame structure 11 is folded. Although not shown, the wall plates 53, 54 may be inserted / removed from the one end opening 58.

  Next, another embodiment of the present invention will be described. FIG. 10 is a plan view showing a playard according to another embodiment of the present invention, FIG. 11 is a front view showing the playard of the embodiment, and FIG. 12 is a side view showing the playard of the embodiment. It is. Regarding the other embodiments, the same components as those in the above-described embodiments will be denoted by the same reference numerals, the description thereof will be omitted, and different configurations will be described below.

  By the way, the playard 10 of the present embodiment is provided with a bar member 13 that is attached to the frame structure 11 at one end side and the other end side and whose center region intersects the bending line 43 to support the floor plate 41. The floor board 41 does not bend and deform at the bending line 43 due to the body weight, and even if the infant actively moves on the floor board 41, the floor board 41 does not bend and deform and can stably support the infant. . Further, only the four column members 14 can support the floor plate 41, and there is no need to further provide short legs that extend downward from the floor plate and come into contact with the installation floor surface as in the conventional playard. Therefore, the clearance space between the floor board 41 and the installation floor surface S can be cleared.

  Further, according to the present embodiment, the frame structure 11 includes a plurality of column members 14 arranged at intervals along the periphery of the infant housing space and a plurality of cross members 15L that connect adjacent column members to each other. , 15R, 16 and at least the cross members 15L, 15R can be bent and deformed in the middle, and the bar member 13 is a straight bar-like body. It is arranged in parallel with 15R. As a result, the rod member can be a rod-like body such as a linear round pipe, square pipe, or angle member, and the bending strength can be increased. Therefore, the rigidity of the frame structure can be improved with a simple structure in the bendable deformable playerd.

  Further, according to the present embodiment, the infant storage space is rectangular in plan view, the column members 14 are arranged at the four corners of the rectangle, and the cross members 15L, 15R, 16 constitute four sides of the rectangle, and these cross members Of the two side members 15L and 15R extending parallel to each other can be bent and deformed in the middle, and two bar members 13 are formed as a pair, and both ends thereof can be bent and deformed in the middle. 15L and 15R are respectively attached to the two pillar members 14 disposed at both ends, and the floor board 41 has first to fourth sides corresponding to the four sides of the rectangle of the infant storage space as contour lines, and of these, One side and the second side extend in parallel to each other, and among these, the third side and the fourth side extend perpendicular to the first side and the second side and are supported by the rod member 13 respectively, and the bending line 43 is the first side. And extends parallel to the second side. Thereby, the infant can be stably supported by the rectangular playard 10.

  Further, according to the present embodiment, the floor plate 41 has a tubular member 42 made of a cloth or a soft sheet that is fixed to the lower surface of the floor plate 41 and through which the bar member 13 is inserted.

  In addition, according to the present embodiment, the column member 14 has a first position where the end portion of the bar member 13 is attached to a relatively low first position and horizontally supports the bar member at a relatively low position. Since it has a bracket 31 and has a second bracket 32 to which the end of the bar member 13 is attached at a relatively high second position and horizontally supports the bar member at a relatively high position, The bar member 13 and the floor plate 41 are selectively attached to a relatively low first position and a relatively high second position. By attaching to the first position of the relatively low frame structure in this manner, it becomes possible to make the height of the bottom plate lower than the playerd, and the infant does not get over the frame structure and leave the playerd. . Therefore, it can be suitably used as a playard. Further, by attaching the floor plate and the bar member to the second position of the relatively high frame structure, the height of the floor plate can be set at the center part or the upper part of the playard, which is suitable as a baby bed where an infant sleeps. Can be used. Parents can easily take care of their infants. Thus, the guardian can suitably use the playard 10 of this embodiment as a playground where an infant plays or as a crib where an infant sleeps.
