Description

Play Yard {PLAY YARD}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a play yard (play pen), and more particularly to a play yard in which a horizontal member can be displaced up and down.

Background Art Conventionally, play yards (play pens) are known to provide a protective space in which children play. The playyard is a frame for dividing the area where the infant is playing, and generally includes a frame structure and a sewing cloth surrounding the frame structure. As such, for example, the pleat of Japanese Patent Laid-Open No. 2008-154752 (Patent Document 1) includes four vertical borders (columns), four upper borders arranged on the upper edges of these vertical borders, and It has four lower borders arranged at the bottom, a bottom plate placed on top of these lower borders, and a frame cover spanning all four vertical borders, and the sides and bottoms of all four sides are closed. This prevents the infants housed inside the playyard from being out of injustice.

Japanese Patent Laid-Open No. 2008-154752

However, in the play yard of patent document 1, the problem as described below arises. In other words, both ends of the horizontal border that extend horizontally in the unfolded state of use are fixed to the top of two neighboring vertical borders. You need to lift it higher than the rim and turn it over. For this reason, it is burdensome to protect children to enter and leave the play yard. In addition, when caring for an infant in the playyard, the guardian has no choice but to reach out from above the infant's head, and there is room for improvement.

SUMMARY OF THE INVENTION In view of the above-described circumstances, an object of the present invention is to provide a play yard which can reduce the burden of such a guardian and facilitate care of a child in the play yard.

For this purpose, the play yard according to the present invention is formed so as to surround the space for accommodating the infant, is arranged at intervals on the outer periphery of the infant accommodating space, and extends in the vertical direction, and It has a plurality of cross member which is installed in a neighboring column and extends in the horizontal direction, and at least a part of the cross member is folded to form a folding structure by bending at a moderate degree, and both ends of the cross member which can be folded at a medium degree. And a pair of connecting members for displaceably connecting the adjacent column members to the upper position and the lower position, and a fastener for holding the end of the cross member that can be bent and deformed at an intermediate position in the upper position. In addition, it is understood that the bending deformation is possible at the intermediate level, and the bending deformation is possible at the location along the longitudinal direction including the longitudinal center portion of the cross member and excluding the longitudinal both ends.

According to this invention, since the both ends of the cross | intersection material which can be bent | deformed in the middle degree are provided with a pair of connection member which connects to two adjacent pillar materials so that displacement is possible to an upper position and a lower position, the height position of a cross member Is changeable, and it becomes possible to lower the height position of the cross member through the connecting member. Thus, the guardian can easily enter and exit the infant into the play yard beyond the road where the height is lowered. In addition, when caring for an infant in the playyard, the guardian can reach out from the same line of sight as the infant, and realize a better parenting relationship. If the cross member is moved to an upper position while the play yard is in use, the cross member surrounds all sides of the frame structure together with the award member, and the infant can be accommodated in the play yard.

The present invention is not limited to one embodiment, and the height positions of all the horizontal members may be changeable, and the height positions of some of the horizontal members may be changeable. In addition, the shape of the infant accommodation space may be a regular polygon such as a regular pentagon or a regular hexagon in plan view. In addition, the infant accommodating space may comprise a conformal polygon having an even number of corners in plan view. The pillar material is disposed at each corner of these polygons. The infant accommodating space may be a square such as a square or a rectangle in plan view. In the play yard in which the infant receiving space constitutes a rectangle in plan view, the cross member constituting the long side of the rectangle is called a front rim, and the guardian passes the infant through the front rim. Thus, as a preferred embodiment, the infant accommodating space constitutes a rectangle in plan view, and the connecting member is provided in two pillars arranged at both ends of the long side of the rectangle in plan view. According to this embodiment, it becomes possible to lower the rectangular long side, that is, the height position of the front edge. Thus, the infant can easily enter and leave the front rim, and the guardian can easily cross the front rim and take care of the infant in the play yard, improving the function.

The structure of the connecting member is not particularly limited as long as it connects both ends of the column member and the horizontal member which can be bent and deformed at an intermediate level. For example, the upper and lower ends of the column member are provided with holes for receiving the end portions of the member, respectively. The end of the cross member may be detachably inserted into the hole to be received. For example, the rail extending in the vertical direction may be provided in the pillar and guided so that the end of the horizontal member does not fall off the rail. Further, for example, a plurality of pipes may be provided at the upper end of the pillar and can be pulled out upward by nesting, such as a fishing rod. For example, the height position of a cross member may be changed by connecting the base of an arm in the middle of a pillar, connecting the edge part of a cross member to the tip of an arm, and rotating an arm.

For example, the fastener may be provided with a friction member at each end of the cross member, and the end of the cross member may be fixed to the upper end of the column member by friction. Further, for example, the engaging member and the engaging member, which are a combination of a rough portion and a recessed portion, are provided at the end of the cross member and the upper end of the pillar, and the end of the cross member is fixed to the upper end of the pillar by the engagement action. good. The structure may be configured to release the engagement by applying a force equal to or greater than a predetermined load to the end of the cross member to separate or press down the cross member, or to automatically engage the end of the cross member by pulling the end of the cross member to the upper end of the column member along the rail. Further, for example, the pipes in a nested manner may be fixed by friction or engagement in a state where they are most stretched upward.

As a preferred embodiment, the connecting member includes a slide member formed with a through hole through which the pillar material is inserted and slid along the pillar material, and the fastener is provided on the slide member, and the pillar member inserted into the through hole in the on state. It restricts the slide of the slide member relative to the slide member, and allows the slide member to slide against the pillar member inserted into the through hole in the off state. According to this embodiment, since the slide of the slide member is regulated in the state where the fastener is turned on, the slide member can be fixed to the pillar material from a desired height position. Therefore, the cross member which can be bent and deformed moderately can be maintained at a desired height position, and a function improves. Also, unless the guardian operates the fixture, the slide member is securely fixed to the upper end of the column, so that there is no fear that the cross member which can be bent and deformed at an intermediate level during use of the play yard falls down unexpectedly.

In a yard provided with a rug plate (also referred to as a bottom plate) attached to the lower part of the frame structure and supporting the infant, the conventional rug plate is always located under the play yard, and its height is not adjusted. On the other hand, in a preferred embodiment of the present invention, there is also provided a rug plate which is selectively attached to the lower portion of the frame structure or the middle portion in the vertical direction and constitutes the bottom surface of the infant receiving space, and the slide member is provided on the upper portion of the frame structure or the like. It is fixed to the middle part in the vertical direction. According to this embodiment, the rug is attached to the upper and lower middle portions of the frame structure, and the infant is laid on the rug so that the play yard can also be used as a bed for laying the infant. By lowering the slide member to the upper and lower middle portions of the frame structure, the protector can easily take care of the infant while sleeping.

The cross member which extends in the horizontal direction in the use state of the expanded play yard can be bent and deformed, and the frame structure can be folded by bending the deformable member. As a preferable embodiment, the horizontal member which can be bent | deformed by the intermediate | middle degree which both ends connect with a pair of slide member is the one rod member which one end part connects with one slide member so that rotation is possible, and the one end part is the other slide member. The other rod member for rotatably connecting with each other, the central connecting member for rotatably connecting with the other end of the other rod member and the other end of the other rod member, and the one-way locking mechanism for making the one rod member and the central connecting member impossible to rotate. And a lock mechanism that releases the lock mechanisms of both sides by simultaneously releasing the lock mechanisms of both the lock rods and the center connecting member.

According to this embodiment, the guardian of the infant has a lock operating mechanism for releasing both lock mechanisms at the same time and having a lock operation mechanism for releasing both lock mechanisms at the same time. When the lock operating mechanism is released, both the lock mechanism on the one side and the lock mechanism on the other side are reliably released. Thereby, folding operation of a play yard can be performed easily.

Thus, in this invention, when the height position of the cross member which can be bend | deformed by the intermediate | middle degree can be changed, and normally puts the cross member which can be bent | deformed by the intermediate | middle degree to the upper position, the middle part can be deformed at the moderate enough position. The child in the play yard can be accommodated so that it does not come out. Furthermore, since this invention is equipped with the fixture which hold | maintains the intermediate | middle deformable cross member in the upper position, it becomes possible to hold | maintain the intermediate member which can be deformed in the middle part in the upper end of a pillar material during use of a playyard, A moderately deformable cross member can be held at the same height position as the upper end of the pillar to surround the frame structure with the award member and to accommodate the infant in the play yard.

And when the intermediate | middle deformable cross member is made into the lower position, the intermediate | middle deformable cross member can be made lower than a normal position. Therefore, the guardian can easily enter and exit the infant into the play yard over the middle of the low deformable cross section. In addition, when caring for a child in a play yard, the guardian can move to the lower side of the cross section which can be deformed to a moderate degree, and it is possible to reach out with the same eye as a child, and realize a better parenting relationship.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described in detail based on the Example shown to drawing.

1 to 4 show an overall outline of a play yard which is one embodiment of the present invention, and show a use state in which the play yard is expanded. 5 and 6 are enlarged front views of the slide member. 7 is a bottom view showing the overall outline of the play yard. 8 to 10 show the folded state of the playyard. The play yard 10 includes a frame structure 11 constituting a skeleton of the play yard 10, a foam member 12 attached to the frame structure 11 and surrounding the outer circumference of the frame structure 11, and a frame. A rod member 13 detachably attached to the structure 11 and a rug plate 41 supported by the rod member 13 are provided.

Since the play yard 10 of the present embodiment is a schematic rectangle in plan view, for convenience, the pair of long side portions may be one side of the play yard, the other side of the yard, the left side of the yard, the right side of the yard, the side of the play yard, and the play yard. It is called both sides or a playyard left and right side part. The pair of short sides is also referred to as one end of the play yard, the other end of the yard, the front end of the yard, the end of the yard, the end of the yard, the ends of the yard, or the front and rear ends of the yard. The play yard 10 can be used as a fence to play the infant, and can also be suitably used as a bed for laying the infant as described later.

First, the frame structure 11 will be described. The frame structure 11 includes four pillar materials 14 extending in the vertical direction, a pair of horizontal members 15L and 15R provided on both sides of the play yard, and a play yard. A pair of cross member 16 and 16 provided in the both ends, and the cross pipe 17 arrange | positioned so that it may become diagonal in plan view are included.

The pillar material 14 is arrange | positioned so that it may stand up in the corner part of a four corner in plan view. A horizontal member 16 is installed between two pillar members 14 and 14 arranged at one end of the play yard. Similarly, the cross member 16 is also provided between the two pillar members 14 and 14 arranged at the other end of the yard. Similarly, a horizontal member 15R is provided between two pillar members 14 and 14 arranged on one side of the play yard. Specifically, the ends of the bar members 16 and 15R are rotatably connected to the upper end block 14B of the column member 14, and when the play yards are folded, the bar members 16 and 15R are formed of the column member ( It is rotatable to approach 14). In addition, the cross member 16, the central connecting member 20 provided in the center portion, the pipe 161 extending in one longitudinal direction from the central connecting member 20, and the pipe extending in the other longitudinal direction from the central connecting member 20. 162. Pipe 161 and pipe 162 are the same length.

In addition, the cross member 15R includes a central connecting member 20 provided in the center portion, a pipe 151 extending in one longitudinal direction from the central connecting member 20, and a pipe extending in the other longitudinal direction from the central connecting member 20. And 152. Pipe 151 and pipe 152 are the same length and longer than pipes 161 and 162.

In the use state of the play yard, the central connecting member 20 locks the pipe 161 extending in one longitudinal direction from the central connecting member 20 and the pipe 162 extending in the other longitudinal direction, and the cross member 16 is As shown in FIG. 3, it is kept in a straight line. 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 play yard 10 is folded, the pipes 161 and 162 are extended upward from the center connecting member 20, as shown in FIG. 9 mentioned later, and the cross member 16 becomes a V shape. Similarly, the middle member 15R is provided with a center connecting member 20, and is straight in the use state of the play yard, and is bent and deformed at the center in the folded state of the play yard. Then, the pipes 151 and 152 extend upward from the center connecting member 20, so that the cross member 15R becomes V-shaped.

In addition, only the horizontal member 15L among the plurality of member members is slidably connected to the pillar member 14 via the slide members 18 of two places on the right side of the yard. Specifically, a through hole 72 extending in the vertical direction is formed in the slide member 18, the pillar material 14 penetrates the through hole 72, and the pair of slide members 18 are pillar materials. It is possible to slide in accordance with (14). Usually, the slide member 18 is incapable of sliding with the fixture 19 mentioned later, and the slide member 18 is fixedly supported by the upper end part of the pair of pillar material 14 arrange | positioned at the right side of the play yard, respectively. In addition, the slide member 18 is rotatably connected to the end of the cross member 15L and the connecting shaft 71, so that the cross member 15L approaches the pillar member 14 when the play yard 10 is folded. Can be rotated. In addition, one longitudinal pipe 151 of the cross member 15L is shorter than the one pipe 151 in the longitudinal direction of the cross member 15R by the size of the slide member 18. Similarly, the other pipe 152 in the longitudinal direction of the bar member 15L is shorter than the pipe 152 in the other longitudinal direction of the bar member 15R by the dimensions of the slide member 18.

An upper portion of the slide member 18 is provided with a shading portion 77 extending beyond the connecting shaft 71 toward the center connecting member 20. Since the receiving part 77 receives the pipe 151 as shown in FIG. 5 and FIG. 6, the pipe 151 does not rotate above the slide member 18 around the connecting shaft 71. However, the pipe 151 can be rotated below the slide member 18 around the connecting shaft 71. Similarly, the pipe 152 is pivotally connected to the slide member 18. Similarly, the pipes 151 and 152 of the cross member 15R and the pipes 161 and 162 of the cross member 16 are also pivotally connected to the upper end block 14B.

The cross member 15L extends in a straight line as shown in FIGS. 2 to 4 in the use state of the play yard. However, in the folded state of the play yard, it deforms in the center part. And as shown in FIG. 8, the pipes 151 and 152 extend upward from the center connecting member 20, and the cross member 15L becomes a V shape.

In the slide member 18, a linear pipe 73 extending in parallel with the through hole 72 is fixed between the connecting shaft 71 and the through hole 72. The upper end of the pipe 73 is positioned approximately the same as the connecting shaft 71, and the length of the pipe 73 is about half of the pillar material 14. The pipe 73 is provided with a fastener 19 orthogonal to the pipe 73. The fixture 19 penetrates through the through hole 73h which is drilled in the pipe 73 and extends in the transverse direction, and is fixed to the end of the shaft portion 74 and the shaft portion 74 whose both ends protrude from the through hole 73h. It extends in a spiral shape so as to cover the outer circumference of the shaft portion 74 and the hat-shaped cap shape with the awning, and contracts between the awning portion of the tip portion 75 and the outer circumferential surface of the pipe 73. Return spring 76 and grip portion 77 fixed to the rear end of shaft portion 74.

The shaft portion 74 is biased toward the pillar member 14 side by the return spring 76, and the tip portion 75 abuts against the pillar member 14. The tip portion 75 is separated from the pillar material 14 by pulling the grip portion 77 with a force greater than the force of the return spring 76. In addition, since the dimensions of the grip portion 77 and the tip portion 75 are larger than the inner diameter of the through hole 73h, the shaft portion 74 does not fall out of the through hole 73h.

When the slide member 18 is located in the upper end part of the pillar material 14, the front-end | tip part 75 of the fixture 19 enters and engages the hole 14h formed in the pillar material 14, and engages. In this on state, the slide member 18 becomes incapable of sliding and cannot slide along the pillar material 14.

When the protector of the infant pulls the fastener 19 against the force of the return spring 76, the tip member 75 is released from the hole 14h, and the engagement is released. In such an off state, the slide member 18 becomes incapable of sliding and can slide along the pillar material 14. When the fasteners 19 of the respective slide members 18 and 18 are pulled to enable the pair of slide members 18 to slide, the cross member 15L is a pair of slides as shown by arrows in FIG. 6. It moves downward with the member 18. And as shown in FIG. 4, it will be in the position of the intermediate part of an up-down direction. This makes it easier for children to enter and exit the play yard 10 beyond the street member 15L. In addition, the guardian may simply reach out to the infant in the playyard 10 beyond the crossbar 15L. In addition, when the guardian sees the cross member (15L) is also called the front border because it is located in the closest position among the four cross members.

As shown in FIG. 4, the horizontal member 15L can be lowered to a height position approximately equal to the top edge of the wall plate 53 attached to the middle portion of the frame structure 11 in the vertical direction. The lower edge of the wall plate 53 connects with the rug plate 41. The rug plate 41 attached to the upper and lower middle portions of the frame structure 11 is used as a bed for laying down the infant. In this manner, the slide member 18 and the cross member 18L are pressed down to the middle portion of the frame structure 11 in the vertical direction, whereby the protector can easily take care of the infant while sleeping.

The cross pipe 17 is X-shaped, and is arrange | positioned diagonally in the lower surface of the rectangular play yard 10, as shown in FIG. Specifically, the cross pipe 17 is composed of a central connecting member 23 disposed at the center of an X letter, and four pipes 171 to 174 connecting to the central connecting member 23 and each pillar 14. do. One end of the pipes 171 to 174 is rotatably connected to the pillar 14, respectively. In addition, the other ends of the pipes 171 to 174 are rotatably connected to the central connecting member 23, respectively. The center connecting member 23 allows the four pipes 171 to 174 to rotate to face downward of the center connecting member 23, but restricts the rotation to face upward of the center connecting member 23. . In the use state of the play yard, the cross pipe 17 can maintain the X-shaped state. 8 to 10, in the folded state of the play yard, four pipes 171 to 174 are concentrated below the central connecting member 23, so that the cross pipe 17 is smallly folded.

A wheel 21 and a wheel cover 22 surrounding the outer circumference of the wheel 21 are provided at the lower ends of the two pillar materials 14 and 14 arranged at the other ends of the play yard. The wheel 21 protrudes from the lower end of the wheel cover 22 and is grounded to the play yard mounting upper surface S. FIG. 2, part 22s of the inside of the play yard of the wheel cover 22 projects further downward than part of the outside of the play yard of the wheel cover 22 to be grounded to the play yard mounting upper surface S. As shown in FIG. . For this reason, in the normal use state in which all the pillar materials 14 are grounded to the playyard mounting top surface S, the wheel 21 is prevented from rolling on the playyard mounting top surface S. FIG.

However, when one end A of the play yard 10 shown on the left side of the ground of FIG. 2 is lifted up when the play yard 10 is not used, the wheel cover protrusion 22s is separated from the installation top surface S. In addition, the wheels 21 are grounded to the installation upper surface (S). For this reason, the play yard 10 of the developed state and the folded state is inclined, and the pillar material 14 at one end of the play yard is removed from the bottom surface S, and the wheel 21 at the lower end of the pillar material 14 at the other end of the play yard. By only grounding), the play yard 10 can be easily transported.

As described so far, the cross members 15L, 15R, and 16 can be deformed at the center, respectively, and the cross pipe 17 can be deformed at the center, and the cross members 15L, 15R, 16 and the cross pipe ( Since the edge part of 17) is rotatably connected with the pillar material 14, the frame structure 11 has the expanded use state shown in FIGS. 1-4, and the folded state shown in FIG. 8-10. It can be modified in two forms.

Next, the foam member 12 will be described. The foam member 12 is formed of a material such as a net or cloth of about several millimeters, and has four surfaces between the four core members 14. It is attached firmly to each. And the upper end of the foam member 12 is suspended on the horizontal member (15L, 15R, 16). In addition, the lower end of the foam member 12 is at the same height position as the cross pipe 17. This reliably surrounds the rug plate 41 provided above the foam member 12 and the cross pipe 17. As shown in FIG.

In other words, in the award member 12 suspended from the cross member 15L, both edges of the upper region are attached to a pair of pipes 73 and 73, and both edges of the lower region are of a pair. It is attached to the pillar materials 14 and 14. Thereby, when the cross member 15L is pressed down from the upper end of the pillar member 14, the foam member 12 also moves downward with the cross member 15L.

Next, the rod member 13 will be described. The rod member 13 is a pair of rod-shaped bodies extending linearly at both sides of the play yard, which are in a horizontal posture, and both ends are attached to the pillar member 14. do. The rod member 13 can be attached to the lower end of the pillar material 14, as shown in FIG. In addition, the rod member 13 can be attached to the center part of the pillar material 14, as shown in FIG. In this way, the rod member 13 may be selectively attached to the lower end and the center portion of the pillar material (14).

That is, referring to FIG. 2 and FIG. 3, two brackets 31 and 32 having different height positions are attached and fixed to each pillar member 14. The bracket 31 is fixed slightly above the cross pipe 17 as the lower end region of the pillar material. The bracket 32 is fixed to the center part of the pillar material 14. The brackets 31 and 32 support the ends of the rod member 13. The hard rod member 13 is a pipe having sufficient bending strength and shear strength in addition to the load of the infant to withstand the impact load when the infant is actively moving. Thus, both ends are attached to the bracket 31 or the bracket 32. The rod member 13 thereby stably supports the infant carried on the upper surface of the rug plate 41. And even if the infant is actively active on the rug, the cross member 15L, 15R, 16 can be prevented from being deformed.

Next, the rug plate 41 will be described. Since the rug plate 41 of the present embodiment is rectangular in plan view, the pair of long side portions is referred to as one side edge, the other side edge, or both side edges for convenience. Moreover, a pair of short side part is called one end, the other end, or both ends.

As shown in FIG. 7, the rug plate 41 has a tubular member 42 having both long and narrow openings. The cylindrical member 42 is made of cloth and is bonded to the lower surface of the rug plate 41 at both sides. The rod members 13 are inserted through the pair of left and right cylindrical members 42, respectively, and both ends of the rod members 13 protrude from the cylindrical members 42.

The rug plate 41 includes a hard core material having sufficient strength so as not to be deformed by the load of the infant, and the surface is formed of a relatively soft material. In addition, as shown in Fig. 7, the rug plate 41 is formed with three equal intervals in the curved line 43 extending in the play yard short side direction. The rug plate 41 can be bent and deformed by these curved lines 43, and becomes a square cylinder at the time of folding the play yard, and surrounds the folded frame structure 11 as shown in FIG. . Further, the rug plate 41 serving as a square tube bundles the folded frame structure 11, a pair of rod members 13, and wall plates 53 and 54 connected to both side edges of the rug plate 41. .

With the covering plate 41 unfolded and stretched flat to attach the rod member 13 to the bottom surface of the covering plate 41, as shown in FIG. 1, the central region of the hard rod member 13 is three. The rug plate 41 is intersected at right angles to the four bend lines 43.

11 is an exploded perspective view showing the rug plate 41 and the wall plate taken out. In the rug plate 41, the first wall plate 51 extends at one end of the playyard, and the second wall plate 52 extends at the other end of the playyard. The first wall plate 51 and the second wall plate 52 also include a hard core material having the same strength as the rug plate 41, and the surface is formed of a relatively soft material. In other words, the first wall plate 51, the rug plate 41, and the second wall plate 52 are one member.

The boundary line 55 between the rug plate 41 and the first wall plate 51 is a curved line, and as shown in FIG. 11, the first wall plate 51 is deformed at 90 ° from the boundary line 55 and is horizontally rugged. It is erected from the plate 41. The boundary line 55 between the rug plate 41 and the second wall plate 52 is also a curved line, and the second wall plate 52 is also erected from the rug plate 41.

As shown in FIG. 11, the cylindrical members 56 and 57 of an opening of both ends are attached and fixed to the both side edges of the rug plate 41. As shown in FIG. One end opening 58 of the cylindrical members 56 and 57 is fixed to the first wall plate 51 and the other end opening 59 of the cylindrical members 56 and 57 is fixed to the second wall plate 52. do. Further, the cylindrical member 56 is attached and fixed along one side edge of the rug plate 41, and the cylindrical member 57 is attached and fixed along the other side edge of the rug plate 41.

The tubular members 56 and 57 are made of cloth and are covered by knocking down the first wall plate 51 on the rug plate 41 and knocking down the second wall plate 52 on the rug plate 41. It is folded along the upper surface of the plate 41. As shown in FIG. 11, the first wall plate 51 is set at an angle of 90 degrees with respect to the rug plate 41, and the second wall plate 52 is set at an angle of 0 degree with respect to the rug plate 41. The cylindrical members 56 and 57 made of cloth are also erected so that the four sides of the rug plate 41 are surrounded by the wall plates 51 and 52 and the cylindrical members 56 and 57.

As shown by the arrow in FIG. 11, the 3rd wall board 53 can be inserted into the cylindrical member 56 from the other end opening 59, and the 4th wall member 57 is inserted into the cylindrical member 57 from the other end opening 59. FIG. Wall plate 54 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 four wall plates 51 to 54 are removed from the rug plate 41. Erected and surrounded everywhere. The standing height of the four wall boards 51-54 is 15 cm or more from the upper surface of the rug board 41. As shown in FIG. This eliminates the possibility that the head of the infant is caught in the gap between the wall plates 51 to 54 and the infant's urine even when the infant's urine is laid on the rug plate 41 and the infant's infant is laid on the infant's urine.

The rug plate 41 and the wall plates 51 to 54 constitute a box-like body 61. The first wall plate 51 is widened from one side edge of the rug plate 41 to the other side edge, and the second wall plate 52 is also widened from one side edge to the other side edge of the rug plate 41. In addition, the third wall plate 53 extends from one end of the rug plate 41 to the other end, and the fourth wall plate 54 also extends from one end of the rug plate 41 to the other end. Thus, in the assembled box-like body 61, each wall plate is erected with almost no gap with the neighboring wall plate.

When assembling the play yard 10, the rug plate 41 is unfolded, and a pair of rod members 13 extending immediately are passed through the tubular members 42 on the bottom surface of the rug plate, and once the opening 58 or The box boards 61 are formed by inserting the wall plates 53 and 54 from the other end opening 59. Further, the frame structure 11 is developed, and the box-shaped body 61 is inserted from above the deployed frame structure 11, and the end of the rod member 13 is attached to the bracket 31 or the bracket 32 of the frame structure 11. ) As a result, the play yard 10 is in use.

The top surface of the rug 41 provides a place for the child to play or sleep. In this embodiment, in particular, it is possible for the protector to select the bracket 31 or the bracket 32 to attach the rod member. By selectively changing the height position of the rug plate 41 in this way, it can be used as a play yard and a baby bed.

As shown in FIG. 2, the end of the rod member 13 is engaged with the relatively low bracket 31, and the rug plate 41 is set in a relatively low first position. By attaching the rug plate 41 to the lower part of the frame structure 11 in this manner, the award member 12 can be used upright to the upper part of the frame structure 11 and can be suitably used as a fence (play yard) for playing with the infant. .

As shown in FIG. 3, the end part of the rod member 13 is engaged with the relatively high bracket 32, and the rug plate 41 is set in a relatively high 2nd position. By attaching the rug plate 41 to the middle portion of the frame structure 11 in the vertical direction, the rug plate 41 is closer to the upper portion of the frame structure 11 than in the case of the play yard described above, and the bed for laying the infant down. It can be used suitably as a (baby bed).

When folding the play yard 10, the box-like body 61 is taken out from the frame structure 11 and disassembled in the reverse order to the above, and the frame structure 11 is folded. In addition, although not shown, the wall plates 53 and 54 may be made to go in and out from the opening 58 once, although not shown in the figure.

Next, the horizontal members 15L and 15R at both sides of the yard having the center connecting member 20 and the pipes 151 and 152, and the horizontal ends at the both ends of the playyard having the central connecting member 20 and the pipes 161 and 162. The ashes 16 and 16 will be described in detail. In addition, since these length members 15L, 15R, and 16 differ only in the length of a pipe, and all the mechanisms of the bending deformation in the center connecting member 20 are common, the width members 15L, 15R, and 16 are representative. Explain.

12 is a plan view showing the central portion of the cross member and showing the center connecting member 20 in cross section. It is a front view which takes out and shows the center part of a street material, and the right side of the paper surface is shown by some cross section. FIG. 14: is explanatory drawing which shows the cross section in XIV-XIV of FIG. FIG. 15 is an explanatory diagram showing a cross section of XV-XV in FIG. 8. 12 to 15 show a state in which all of them are locked to no rotation. Fig. 16 is a front view showing the center connecting member taken out.

The cross member 16 is rotatably connected to the pipe 161 serving as one longitudinal member, the pipe 162 serving as the other longitudinal member, and the pipe 161 and the pipe 162 serving as the longitudinal center portion. The central connecting member 20, the one-way locking member 241 as the one-lock mechanism for disabling the pipe 161 and the central connecting member 20, and the pipe 162 and the central connecting member 20. The other locking member 242 serving as the other locking mechanism that cannot be rotated relative to each other, and the button 25 serving as the locking operating mechanism for releasing both of the locking mechanisms at the same time and maintaining the unlocking of both.

For convenience of explanation, the pipe 161 is made to the left and the pipe 162 is made to the right as viewed from the center connecting member 20, hereinafter referred to as left and right directions. 12 and 13, the center connecting member 20 is formed symmetrically with respect to the center line C passing through the center in the left and right directions, and the pipe 161 and the pipe 162 are the center line C. Are arranged symmetrically with respect to.

As shown in FIG. In addition, of both ends of the pipe 162, the end portion in the longitudinal center side is rotatably connected to the other end of the central connecting member 20 through the connecting shaft 262. The central connecting member 20 has a pair of wall portions 201 and 202 facing each other with a gap. Connecting shafts 261 and 262 are installed on these wall portions 201 and 202. Moreover, the other end of the pipes 161 and 162 which are not shown in FIG. 13 connects to the upper end block 14B of the pillar material 14 so that rotation is possible. The central connecting member 20 also has an intermediate wall portion 203, which is coupled to the upper ends of the pair of wall portions 201 and 202, respectively. As shown in the cross-sectional views of Figs. 14 and 15, the wall portions 201 to 203 are arranged in a c-shape as viewed in cross section.

Since the pipe 161 extending in the horizontal direction abuts against the wall portion 203 at the end side of the connecting shaft 261, the downward movement of the pipe 161 is controlled below the central connecting member 20. On the other hand, the pipe 161 is allowed to rotate upwards than the center connecting member 20. However, while the pipe 161 engages with the one-way lock member 241 on the end side of the connecting shaft 261, the upward rotation is also restricted, whereby the pipe 161 is connected to the center connecting member 20. It is locked by the non-rotatable.

Since the pipe 162 extending in the horizontal direction also comes in contact with the wall portion 203 at the end side of the connecting shaft 262, the rotation downward of the central connecting member 20 is restricted. On the other hand, the pipe 162 is allowed to rotate upward than the center connecting member 20. However, while the pipe 162 is engaged with the other lock member 242 on the end side of the connecting shaft 262, the upward rotation is also restricted, whereby the pipe 162 is connected to the center connecting member 20. It is locked by the non-rotatable.

As shown in FIG. 13, the central connecting member 20 is projected downward from the connecting shafts 261 and 262 extending in parallel with each other, and includes a connecting shaft 261 and 262 thereof. The locking members 241 and 242 are attached below the plane.

In other words, the connecting shafts 261 and 262 extending in parallel to each other are left and right symmetrical and left and right symmetrical with respect to the virtual center plane passing through the center of the center connecting member 20. This center plane is represented by the center line C in FIGS. 12, 13, 16, and FIGS. 17 and 18 described later.

The wall 202 is placed inside the play yard, with the infant receiving area surrounded by the four cross members 15L, 16, 15R, and 16 on the inside of the play yard, and the outside of the child receiving area being outside the play yard. The wall portion 201 is disposed outside the play yard.

The lock member 242 is disposed on the right side, and the shapes of both 241 and 242 are left and right symmetrical and left and right symmetrical with respect to an imaginary central plane passing through the center of the center connecting member 20. So, in order to avoid duplication of description, the other lock member 242 is mainly demonstrated below.

As shown in FIG. 13, the other lock member 242 is interposed between the pair of wall portions 201 and 202. Then, a through hole 244 having a circular cross section is formed on the center line C in the left and right directions. The through-holes 244 are aligned with the through-holes 243 of the one-way lock member 242 similarly formed, and a common connecting pin 27 passes through these through-holes 243 and 244.

As shown in FIG. 13, a pair of long holes 20a are drilled in the wall portions 201 and 202 on the center line C in the left and right directions. 13, the pair of long holes 20a are in the same shape, the same dimension, and the same position, extend in the vertical direction, and engage with both ends of the connecting pin 27, respectively. Thereby, the connecting pin 27 is guided by the long hole 20a and can move to an up-down direction. In addition, since the long hole 20a extends in the direction perpendicular to the extending direction of the connecting pin 27, the connecting pin 27 moves perpendicularly to the pin extending direction along the center line C.

At the lower end of the other lock member 242 farthest from the center line C, the central region of the other prevention paper pin 246 of the circular cross section is fixed. A pair of long holes 20b which both ends of the other anti-finger pins 246 protrude toward the wall portions 201 and 202, respectively, are drilled into the wall portions 201 and 202 on the right side of the center line C and extend in the left and right directions. ) Since the pair of long holes 20b are in the same shape, the same dimension, and the same position when viewed from the front as shown in FIG. It is possible. Similarly, a pair of long holes 20b are punctured on the left side of the wall portions 201 and 202 than the center line C, too. In addition, similar to the other prevention paper pin 246, the one-stop paper pin 245 is fixed to the one-way lock member 241, the one-stop paper pin 245 is guided to the long hole 20b on the left side of the center line (C) to the left and right Can move in the direction.

As shown in FIG. 16, a pair of long holes 20a are drilled in the wall portions 201 and 202 along the center line C, and two pairs of long holes 20b are symmetrically with respect to the center line C. FIG. It is perforated. In addition, a pair of through-holes 20c are arranged in the wall portion 201 arranged symmetrically with respect to the center line C. FIG. 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 drilled are drilled into 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. FIG.

An inclined surface 282 is formed at a position away from both the other prevention paper pin 246 and the connection pin 27 in the other lock member 242. The inclined surface 282 is disposed at the upper end of the other lock member 242 and inclined with respect to the extending direction of the connecting pin 27 and the other prevention paper pin 246, and is directed near the wall portion 201 as shown in FIG. do. The inclination of the inclined surface 282 is located at the lowermost side at the portion near the wall portion 201 and gradually moves upward as it approaches the wall portion 202.

The inclined surface 282 is formed near the wall portion 201 of the other lock member 242. On the other hand, near the wall part 202 of the other lock member 242, the surface 284 parallel to the axis line of the connection pin 27 and the other prevention paper pin 246 is formed. The parallel surface 284 and the inclined surface 282 are continuously formed in the axial direction of the connecting pin 27 and the other prevention paper pin 246.

Further, the inclined surface 282 is proximate to the tip of the leg portion 252 which protrudes from the button 25 and extends toward the wall portion 202. On the lower end side of the tip of the leg portion 252, a leg portion inclined surface 252c formed by notching to correspond to the inclined surface 282 is formed. Similarly, the inclined surface 281 and the parallel surface 283 are formed in the one-way lock member 241, and the inclined surface 281 is close to the leg inclined surface 251c formed at the tip of the leg portion 251.

An engagement protrusion 292 protruding upward is formed at a position farthest from both the other prevention paper pin 246 and the connection pin 27 among the other lock members 242. The engagement protrusion 292 is at a position furthest from the center line C during the other stage of the other lock member 242, that is, in the vicinity of the pipe 162. As shown in FIG. 15, the distal end of the engaging projection 292 is an arcuate curved surface corresponding to the outer peripheral surface of the pipe 162. Therefore, the tip shape of the engaging projection 292 protrudes upward from the portion near the wall portion 201 and the portion near the wall portion 202 than the portion between the wall portions 201 and 202.

In the lock position of the other locking member 242, the connecting pin 27 becomes the upper end of the long hole 20a, and the other prevention paper pin 246 becomes the end closer to the center line C of the long hole 20b. The engagement protrusion 292 of the other lock member 242 engages and supports the outer circumferential surface of the pipe 162 from below. As a result, the pipe 162 cannot be rotated around the connecting shaft 262.

Similarly, the engagement protrusion 291 of the one-way lock member 241 engages to support the outer peripheral surface of the pipe 161 from below. As a result, the pipe 161 is disabled in relative rotation around the connecting shaft 261. In addition, in the lock position of the other lock member 242 shown in FIG. 13, the connecting pin 27 is located in the upper end of the long hole 20a, and the other prevention paper pin 246 is center line C among the long holes 20b. Located at the nearest stage to. And the leg portion 252 is at the position farthest from the wall portion 202. 12 and 14, the button 25, which is an operator for simultaneously operating the two lock members 241 and 242 at the lock position of the one lock member 241 and the other lock member 242, is provided with a wall portion ( 201) is the furthest from the position. The leg inclined surface 252c is in contact with the portion of the inclined surface 282 near the wall portion 201.

As described so far, the one-lock member 241 and the other lock member 242 are supported by the center connecting member 20, respectively, and as shown in FIGS. 12 to 15, the rotation of the pipes 161 and 162 is performed. The lock position is disabled. In addition, the one lock member 241 and the other lock member 242 are selectively positioned at a free position to allow the pipes 161 and 162 to rotate as shown in FIGS. 17 to 19.

Fig. 17 is a plan view showing the central portion of the unlocked cross member, showing the center connecting member 20 in cross section. Fig. 18 is a front view showing the central portion of the unlocked cross member taken out and the right side of the ground is shown in partial cross section. It is explanatory drawing which shows the cross section in XIX-XIX of FIG.

When the button 25 is in the original position isolated from the wall portion 201 as shown in Figs. 12, 14, and 15 described above, the tip of the leg portion 251 is the most wall portion 201 of the inclined surface 281. The tip of the leg portion 252 is in contact with the portion near the most wall portion 201 of the inclined surface 282, while contacting a portion near the portion).

The button 25, which is a common operator that operates the two lock members 241 and 242 simultaneously, can slide in the center hole 30h and move in the vertical direction of the wall portion 201. When the button 25 is press-fitted, the button 25 is advanced until it comes in contact with the wall portion 201, and the one-side lock member 241 and the other lock member 242 are provided through the pair of leg portions 251 and 252.

The other lock member 242 also allows the pipe 162 to rotate relative to the center connecting member 20 from the free position.

Specifically, when the button 25 is press-fitted and advanced toward the wall portion 201, the leg portions 251 and 252 advance in the axial direction of the pins 245, 246 and 27 to move the inclined surfaces 281 and 282. Indent each simultaneously. Then, the locking members 241 and 242 are moved downward by receiving the pressure input. At this time, the connecting pin 27 moves downward along the long hole 20a, and the supporting 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 to change their posture.

When the button 25 is advanced to the operation position adjacent to the wall portion 201, the leg portions 251 and 252 are pushed downward by pressing the inclined surfaces 281 and 282, respectively, so that the tip ends of the leg portions 251 and 252 are moved. It reaches the wall 202. As a result, the lock member 242 is in the free position shown in FIGS. 17 to 19, and the lock member 241 is also in the free position with respect to the center line C in a symmetrical attitude. In this way, the button 25 is operated from the original position to the operation position to operate the one lock member 241 and the other lock member 242 from the lock position to the free position.

In the free position of the other lock member 242, the connecting pin 27 becomes the lower end of the long hole 20a, and the other prevention paper pin 246 becomes the end of the long hole 20b farther away from the center line C. , Engagement projection 292 is drawn away from pipe 162 and close to centerline C. As a result, the pipe 162 is free to rotate around the connecting shaft 262.

Similarly, the engaging projection 291 of the one-way lock member 241 is pulled in so as to approach the center line C away from the pipe 161. As a result, the pipe 161 is free to rotate around the connecting shaft 261.

As shown in FIG. 19, in the free position of the other lock member 242, the leg part 252 does not contact the inclined surface 282. As shown in FIG. And the leg part 252 extends in parallel with the parallel surface 284, and makes continuous contact from the wall part 201 side to the wall part 202 side in the parallel plane 284. As shown in FIG. Therefore, even when the other locking member 242 presses the leg portion 252 upward by any force, the leg portion 252 is not moved by the other locking member 242, and the other locking member 242 Keep the free position. Similarly, the leg portion 251 maintains the free position of the one-way lock member 241. As a result, the button 25 holds the lock release.

The lock operating mechanism may also include a return spring for returning the button 25, which is the operator, to its original position. These return springs are inserted between the wall portion 201 and the button 25 to force the button 25 away from the wall portion 201.
