(44) FIG. 2A shows sheeting 24 in a collapsed form where the form is generally flat. FIG. 2A shows lowermost sleeves 28 ready for the insertion therein of the lowermost horizontal support members 16.

(45) FIG. 2B shows a female tubular piece 44 and FIG. 2C shows a male tubular piece 46. When engaged to each other female tubular piece 44 and male tubular piece 46 make up any of the uppermost and lowermost horizontal support members 14, 16. Female tubular piece 44 includes a pin hole 48 or pin opening 48 for a spring biased pin 50 on the male tubular piece 46. Spring biased pin 50 includes a pin shaft portion that extends through an opening in male piece 46 and a base spring portion that lies within the male piece 46. Male piece 46 includes a greater diametrical portion 52 and a lesser diametrical portion 54 separated by an annular stop 56. Lesser diametrical portion 54 is slidingly insertable into an end opening 58 of the female piece 44 until pin 50 snaps into and through pin hole 48 whereupon the male piece 46 is releasably locked to the female piece 44. The male piece 46 may be unlocked from the female piece 44 by pressing upon the spring biased pin 50. Then the male piece 46 is further disengaged from the female piece 44 by sliding the male piece 46 axially out of the female piece 44. The inner diameter of the female piece 44 is slightly greater than or about the same as the outer diameter of the tubular male portion 54 to provide a friction fit between the female piece 44 and male piece 46. The length of male portion 54 is relatively great to provide a relatively great amount of overlap between the female piece 44 and the male piece 46 so as to maximize a straight alignment between the axis of the female piece 44 and the male piece 46 when the pieces 44, 46 are engaged and when transverse pressure in the same direction is applied to opposite ends of the upper and lower horizontal support members 14, 16. Female piece 44 is tubular and cylindrical. Male portion 52 is tubular and cylindrical. Male portion 54 is tubular and cylindrical. The outer diameter of female piece 44 and the outer diameter of the greater diametrical portion 52 of the male piece 46 are the same.

(46) FIGS. 2B and 2C further show the spring biased pins 50 disposed on ends of the pieces 44, 46. On the end opposite the end having pin hole 48, female piece 44 includes a spring biased pin 50 for engaging one of the horizontal sockets 62, 66 of the lower and upper corner connections 20, 22. On the end opposite the end having lesser diametrical portion 54, male piece 46 includes a spring biased pin 50 for engaging one of the horizontal sockets 62, 66 of the lower and upper corner connections 20, 22.

(47) FIGS. 2D and 2E show, respectively, the lower corner connection 20 and the upper corner connection 22. The lower connection 20 has a post socket or receptacle 60 for the lower end of a corner post 18 and a pair of horizontal support member sockets or receptacles 62 for the outer ends of lowermost horizontal support members 16. Socket 60 has an axis that is disposed at a right angle to each of the axes of the sockets 62. Each of the sockets 62 has an axis that is disposed at a right angle to the axis of the other socket 62.

(48) The upper connection 22 has a post socket or receptacle 64 for the upper end of a corner post 18 and a pair of horizontal support member sockets or receptacles 66 for the outer ends of uppermost horizontal support members 14. Socket 64 has an axis that is disposed at a right angle to each of the axes of the sockets 66. Each of the sockets 66 has an axis that is disposed at a right angle to the axis of the other socket 66.

(49) Each of the sockets 60, 62, 64, 66 has a pin hole for a spring biased pin of the corner post or support member that is engaged therein. Each of the sockets 60, 62, 64, 66 is cylindrical and include axially extending and spaced apart straight interior ridges 70 to provide a friction fit of the corner post or support member while, at the same time, minimizing surface area connection for a ready engagement and disengagement of the corner posts and support members to and from the upper and lower connections 20, 22. Such friction fit is between the inner edge of the ridge 70 and the outside face of the corner post or support member.

(50) Each of the upper and lower connections 20, 22 includes a set of three generally triangular shaped braces 72. Each of the braces 72 lies in a plane defined by the axes of two of the sockets 60, 62, 64, 66. Each of the braces 72 extends from a location adjacent to an opening of a socket 60, 62, 64, 66 to a location adjacent to an opening of another socket 60, 62, 64, 66. Each of the braces 72 engages a cylindrical body of one of the sockets 60, 62, 64, 66 to a cylindrical body of one of the other sockets 60, 62, 64, 66.

(51) FIG. 2D shows that the lower corner connection 20 includes a foot 73. Foot 73 is cylindrically shaped with a flat lowermost end. Foot 73 includes an axis that is coaxial with cavity 60 and corner post 18. Foot 73 is one-piece with lower connection 20.

(52) FIG. 2F shows the tubular corner post 18. Playyard 10 includes first, second, third, and fourth corner posts 18. The four corner posts 18 anchor the four corners of the playyard 10. Corner post 18 is a metal tube having an upper open end 74 and a lower open end 76. Upper end 74 includes a spring biased pin 50 and a lower open end 76 that includes a spring biased pin 50 that locks and unlocks with the pin holes 68 of the sockets 60, 64. The length of the corner post 18 is about one-half of the length of each of the uppermost and lowermost horizontal support members 14, 16 such that the length of each of the uppermost and lowermost horizontal support members 14, 16 is about twice the height of the corner post 18 such that the expanse from corner post 18 to corner post 18 is relatively great so as to minimize hardware or hard components of the playyard 10 and maximize soft components of the playyard 10.

(53) FIGS. 3A, 3B, and 3C show the two types of engagement between the female piece 44 and male piece 46. A first type of engagement is the male/female engagement between open end portion 78 of the female piece 44 and lesser diametrical portion 54 of the male piece 46. This is a friction fit with ready engagement and ready disengagement of the pieces 44, 46 to and from each other. This friction fit occurs along the axial length of lesser diametrical portion 54 to annular stop 56 and along the axial length of female piece 44 from an annular stop edge 80 to beyond the pin hole 48. Supplementing such first type of engagement is the second type of engagement where spring biased pin 50 of male piece 46 locks into spring biased pin hole 48. The thumb or a finger of the user pushes down spring biased pin 50 to be generally flush with the diameter of lesser diametrical portion 54, then the user inserts the lesser diametrical portion 54 into the end opening 58 of the female piece 44, then the user pushes the female piece 44 and male piece 46 together until the spring biased pin pops into the pin hole 48, whereupon the female and male pieces 44, 46 are releasably locked together. To unlock the female and male pieces 44, 46 from each other, the button or pin 50 is pressed down and the female and male pieces 44, 46 are slid apart from each other.

(54) FIG. 4 may be compared to FIG. 2A. In FIG. 2A, the lowermost sleeves 28 are empty or void and are in a flat form. In FIG. 2A there is no lowermost horizontal support member 16 in any of the lowermost sleeves 28. In FIG. 4, each of the lowermost sleeves 28 includes a lowermost horizontal support member 16 that has been slid therein. Sheeting 24 remains in the flat form in FIG. 4 with the exception of lowermost sleeves 28. In FIG. 4, each of the outer ends of each of the lowermost horizontal support members 16 is adjacent to and spaced from an outer end of another lowermost horizontal support member 16.

(55) FIG. 5A may be compared to FIG. 4. In FIG. 4, each of the lowermost sleeves 28 has therein one of the lowermost horizontal support members 16. In FIG. 5A, the first, second, third, and fourth lowermost corner connections 20 have been engaged to the outer ends of the lowermost horizontal support members 16. The outer ends of the lowermost horizontal support members 16 have been slid into and releasably locked into the sockets 62, where the releasable lock is provided by the spring biased pins 50 of the outer ends of the lowermost horizontal support members 16 as shown in FIGS. 2B, 2C, and 3A.

(56) Whereas FIG. 2D shows the inner face of lower corner connection 20, FIG. 5B shows the outer face of the lower corner connection 20. It can be noted that pin holes 68 are disposed on the outer faces of socket 62 and socket 60. It can be further noted that the pin hole 68 on socket 60 has an axis that is coplanar with a plane defined by the pair of upper and lowermost horizontal support members 14, 16, that extends from the side of the socket 60 opposite to that where such pin hole 68 is formed. Such pin hole 68 is offset from a diagonal vertical plane that intersects the lower corner connections 20 that are positioned diagonally across or kitty corner from each other in the playyard 10.

(57) FIG. 6A may be compared to FIG. 5A. In FIG. 5A, the first, second, third, and fourth lower corner connections 20 have been engaged to the lowermost horizontal support members 16. In FIG. 6A, the vertical corner posts 18 have been engaged to the first, second, third, and fourth lower corner connections 20 and have further been slid into the first, second, third, and fourth corner post sleeves 30.

(58) In FIG. 6B, it can be seen that the lower end 76 is slid into and releasably locked with socket 60 of the lower corner connection 20. There are two types of engagement here: a male/female engagement between socket 60 and lower end 76 and a pin and pin hole engagement between pin 50 and pin hole 68. Such a two type of an engagement provides sufficient support for the corner post 18 prior to when the uppermost horizontal support members 14 are engaged to the corner posts 18 by the upper corner connections 22.

(59) FIG. 7A can be compared to FIG. 6A. In FIG. 6A, the upper ends 74 of the corner posts 18 are free. In FIG. 7A, the upper corner connections 22 have been engaged to the upper ends 74 of the corner posts 18.

(60) FIG. 7B shows that the pin 50 of the upper end 74 extends in a plane that is coplanar with a plane defined by the uppermost and lowermost horizontal support members 14, 16 that extend from the side of corner post 18 that is opposite from which pin 50 extends.

(61) Once the pins 50 of the upper ends 74 are releasably locked with the pin holes 68 of the upper corner connections 22, the sockets 66 are axially aligned with an opposing socket 66 on another upper corner connection 22 and ready to releasably engage an uppermost horizontal support member 14.

(62) In FIG. 7B, it can be seen that the upper end 74 is slid into and releasably locked with socket 64 of the upper corner connection 22. There are two types of engagement here: a male/female engagement between socket 64 and upper end 74 and a pin and pin hole engagement between pin 50 and pin hole 68.

(63) FIG. 7A shows that the uppermost sleeves 26 are relaxed and ready to accept the uppermost horizontal support members 14.

(64) FIG. 8A shows that the uppermost sleeves 26 have accepted therein and have been engaged to the uppermost horizontal support members 14 and that the uppermost horizontal support members 14 have been engaged to the upper corner connections 22.

(65) In FIG. 8B, it can be seen that the outer ends of the uppermost horizontal support member 14 have been slid into and releasably locked with sockets 66 of the upper corner connection 22. There are two types of engagement here at each of the sockets 66: a male/female engagement between socket 66 and the outer end of the horizontal support member 14 and a pin and pin hole engagement between pin 50 of such outer end and pin hole 68 of the socket 66.

(66) In FIG. 8A, bases 82 can be seen. Bases 82 are engaged to an outer face of upper fabric band 36 at a location adjacent to corner post sleeve 30. The outer face of base 82 includes one of a hook or loop fabric connector such as Velcro.

(67) In FIG. 8A, flaps 42 can be seen. Flaps 42 are flexible and are engaged at a junction 83 formed between uppermost sleeve 26 and upper fabric band 36. In the unengaged state shown in FIG. 8A, flaps 42 hang down from the junction 83.

(68) FIG. 9A can be compared to FIG. 8A. In FIG. 9A, the flaps 42 have been swung up and over the upper corner connections 22 and then flexibly turned downward to engage bases 82. FIG. 9B shows that the underside of flap 42 includes a base 84. Base 84 includes a face having the other of a hook or loop fabric connector such as Velcro such that the bases 82, 84 engaged each other with a macroscopic hook and loop fabric connection to secure the flap 42 over the upper corner connection 22 and to hide from sight the upper corner connection 22. Flap 42 has a width and length greater than a width and height of the upper corner connection 22. There are two bases 82 disposed adjacent to each of the upper corner connections 22 and there are two bases 84 on each of the flaps 42 to engage such two bases 82. FIG. 9A shows the playyard 10 completely set up for use.

(69) FIG. 10A shows the male piece 46 and the female piece 44 where the male piece 46 and female piece 44 are adjacent to each other and about to be engaged to each other. FIG. 10B shows the male piece 46 and female piece 44 of FIG. 10A engaged to each other, and further shows a first lower corner connection 20 adjacent to and about to be engaged with the outer end of the male piece 46 of the lowermost horizontal support member 16. FIG. 10C shows the lowermost horizontal support member 16 of FIG. 10B, and further shows a pair of lower corner connections 20, where one of the lower corner connections 20 has been engaged to the male piece 46 and where the other of the lower corner connections 20 is adjacent to and about to be engaged with the outer end of the female piece 44 of the lowermost horizontal support member 16. FIGS. 10B and 10C show the annular stop edge 80 abutting the annular stop 56 of the male piece 46. In order from FIG. 10A to FIG. 10B to FIG. 10C, such figures show engagement. In order from FIG. 10C to FIG. 10B to FIG. 10A, such figures show disengagement or release of the components from each other.

(70) FIG. 11A shows the lowermost horizontal support member 16 of FIG. 10C having been engaged to first and second lower corner connections 20, with the lower end 76 of corner post 18 about to be engaged to one of the lower corner connections 20 and with the upper end 74 of the corner post 18 about to be engaged with the upper corner connection 22. FIG. 11B shows the lowermost horizontal support member 16 of FIG. 11A and the corner post 18 of FIG. 11A engaged in a lower corner connection 20, and further shows the upper corner connection 22 of FIG. 11B about to be engaged to the upper end 74 of the corner post 18. FIG. 11B shows that an axis of lowermost support member 16 is disposed at a right angle to the axis of corner post 18 when the lowermost support member 16 and corner post 18 are engaged to the lower corner connection.

(71) FIG. 12A shows a set of four lowermost horizontal support members 16 engaged with a set of four lower corner connections 20. FIG. 12B shows the set of four lowermost horizontal support members 16 of FIG. 12A engaged with the set of four lower corner connections 20 of FIG. 12A, which in turn is engaged with a set of four corner posts 18, which in turn is engaged with a set of four upper corner connections 22. The axes of the first, second, third, and fourth lowermost horizontal support members 16 of FIGS. 12A and 12B define a square.

(72) FIG. 13 shows a broken apart view of the frame 12 of the playyard 10 of FIG. 1. Frame 12 includes four lowermost horizontal support members 16, four uppermost horizontal support members 14, four corner posts 18, four lower corner connections 20, and four upper corner connections 22, where each of the uppermost and lowermost horizontal support members 14, 16 includes a female piece 44 and a male piece 46. Frame 12, as shown in FIG. 13, can be set up to the state shown in FIG. 14 without destroying an integrity of any of the components 14, 16, 18, 20, 22, 44, and 46.

(73) FIG. 14 shows an assembled view of the frame 12 of the playyard 10 of FIG. 1. Frame 12 includes four lowermost horizontal support members 16, four uppermost horizontal support members 14, four corner posts 18, four lower corner connections 20, and four upper corner connections 22, where each of the uppermost and lowermost horizontal support members 14, 16 includes a female piece 44 and a male piece 46. Frame 12, as shown in FIG. 14, can be taken down to the state shown in FIG. 13 without destroying an integrity of any of the components 14, 16, 18, 20, 22, 44, and 46. The axes of the lowermost horizontal support members 16 define a square. The axes of the uppermost horizontal support members 14 define a square. The axes of a pair of uppermost and lowermost horizontal support members 14, 16 and the axes of corner posts 18 that are adjacent to such pair define a rectangle. The lowermost horizontal support members 16 define a first plane and the lowermost portions of feet 73 define a second plane, with the first and second planes being adjacent to each other and spaced from each other so as to space floor 40 from a lower surface such as grass, sand, dirt, or another environmental surface on which the feet 73 rest.

(74) FIG. 15A shows a detail view of the lower corner connection 20 of FIG. 2D. FIG. 15B shows a detail view of the upper corner connection 22 of FIG. 2E. The lower and upper corner connections 20, 22 have also been described with respect to FIG. 5B, FIG. 6B, FIG. 7B, FIG. 8B, and other figures. FIG. 15A shows that foot 73 includes a bottommost disk portion 86 that may be formed of a non-slip rubber or elastomeric material to minimize slippage, for example, on a hardwood floor or tiled floor of a residence. The bottommost surface of the disk portion 86 may be concave where the concave portion extends inwardly and upwardly from the outermost edges of the disk portion 86.

(75) FIG. 16A shows a section taken along a vertical plane of an upper portion of the playyard of FIG. 1. FIG. 16A shows the uppermost horizontal support member 14, the uppermost sleeve 26 and the fabric band 36. FIG. 16A further shows an axis A or straight line A that is coplanar with a first plane defined by the axes of the uppermost and lowermost horizontal support members 14, 16 that are paired with each other. Axis A extends through the center of uppermost horizontal support member 14. FIG. 16A further shows a straight line B defined by a second plane. Upper band 36 lies in the second plane, as does the mesh section 34, the lower band 38, and the point of the teardrop shaped uppermost sleeve 26. The point of the teardrop shaped uppermost sleeve 26 lies on a junction 88, where the junction 88 is a junction between the uppermost sleeve 26 and the upper band 36. Junction 88 is shown in FIGS. 1 and 16A. Uppermost band 36, mesh section 34, and lowermost band 38 are coplanar and such second plane is disposed obliquely to the first plane defined by the longitudinal axes of the uppermost and lowermost horizontal support members 14, 16.

(76) FIG. 16B shows a section taken along a vertical plane of a lower portion of the playyard of FIG. 1. FIG. 16B shows the lowermost horizontal support member 16, the lowermost sleeve 28, the fifth sheeting portion 40 or floor 40, and the lower band 38. FIG. 16B further shows axis A or straight line A, which is the same axis A shown in FIG. 16A. As indicated above, axis A is coplanar with a first plane defined by the axes of the uppermost and lowermost horizontal support members 14, 16 that are paired with each other. Axis A extends through the center of lowermost horizontal support member 16 shown in FIG. 16B. In FIG. 16B, to the left of axis A, is an axis C. Axis C lies in a plane parallel to axis A. FIG. 16B further shows straight line B, which is the same straight line B shown in FIG. 16A. FIG. 16B shows that lower band 38 is in the plane defined by axis B. Axis B is oblique to axis C and is thus also oblique to axis A. Lower band 38 leads into mesh section 34 that in turn leads into upper band 36. FIG. 16B further shows axis D or straight line D. FIG. 16B shows that floor 40 or fifth sheeting portion 40 lies in a plane in which axis D lies. As shown in FIG. 16B, a point of lowermost sleeve 28, lower band 38, and floor 40 define a junction 90 shown in FIGS. 1 and 16B. Putting FIGS. 16A and 16B together, it can be appreciated that junction 90 is spaced from a plane defined by uppermost and lowermost horizontal support members 14, 16 and that junction 88 is adjacent to the plane defined by the uppermost and lowermost horizontal support members 14, 16. It can also be appreciated that lower band 38, mesh section 34, and upper band 36 are oblique to the floor 40 as well as being oblique to the plane defined by the uppermost and lowermost horizontal support members 14, 16. From FIGS. 16A and 16B, it can be appreciated that floor 16 has a perimeter defined by first, second, third, and fourth junctions 90. From FIGS. 16A and 16B, it can be appreciated that first, second, third, and fourth junctions 90 define a lower square, that first, second, third, and fourth junctions 88 define an upper square, and that the upper square covers more area than the lower square or that the area enclosed by the upper square is greater than the area enclosed by the lower square. Such a structure, with the perimeter of the floor 40 defining a square of a lesser area than a) the larger square defined by the lowermost horizontal support members 16 that defines a greater area, and b) the larger square defined by the uppermost horizontal support members 14, contributes to a taut or tight sheeting fit within the frame 12 where the sheeting 24 draws inwardly the uppermost and lowermost horizontal support members 14, 16.

(77) FIG. 17 is a section taken along a horizontal plane of an intermediate portion of the playyard of FIG. 1. FIG. 17 shows the teardrop shape of the corner post sleeves 30. FIG. 17 shows the right angle relationship between two adjacent mesh sections 34. FIG. 17 shows the vertical junction 92 defined by the intersection of two adjacent mesh sections 34 and the corner post sleeve 30. From FIG. 8A, it can be appreciated that junction 92 and corner post sleeve 30 has a greater height than mesh section 34 and that corner post sleeve 30 has an uppermost end adjacent to an upper corner connection 22 and that corner post sleeve 30 has a lowermost end adjacent to a lower corner connection 22. From FIG. 8A, it can be appreciated that uppermost sleeve 26 engaging the uppermost horizontal support member 14 has a lesser length than the upper band 36 and also has a lesser length than the mesh section 34. Uppermost sleeve 26 has a first end adjacent to one uppermost corner connection 22 and a second end adjacent to another uppermost corner connection 22.

(78) FIG. 18 shows that the length to height ratio of the playyard 10 is about two to one. In other words, the length of an uppermost horizontal support member 14 plus a portion of one upper corner connection 22 plus a portion of another upper corner connection 22 is about 51 inches, while the height of a corner post 18 plus a portion of an upper corner connection 22 plus a portion of a lower corner connection 20 is about 26.5 inches, which is about a 1.92 to 1.0 ratio. Likewise, the length of an lowermost horizontal support member 16 plus a portion of one lower corner connection 20 plus a portion of another lower corner connection 20 is about 51 inches, while the height of a corner post 18 plus a portion of an upper corner connection 22 plus a portion of a lower corner connection 20 (without considering the foot 73) is about 26.5 inches, which is about a 1.92 to 1.0 ratio. For the square playyard 10, the length of the frame 12 of the playyard 10 is preferably between about 1.80 units and about 2.20 units where the height of the frame 12 of the playyard 10 is 1.0 units without considering the foot 73, where such length is more preferably between about 1.85 units and about 2.10 units where the height of the frame 12 of the playyard 10 is 1.0 units without considering the foot 73, and where such length is most preferably between about 1.90 units and about 2.10 units where the height of the frame 12 of the playyard is 1.0 units without considering the foot 73.

(79) FIG. 19A is a section an embodiment of the playyard 10 where the playyard 10 has no floor 40, and shows the teardrop of the uppermost sleeve 26 for the uppermost horizontal support member 14 pointing straight downwardly. FIG. 19B is a section of the embodiment of the playyard 10 of FIG. 19B where the playyard 10 has no floor 40, and shows the teardrop of the lowermost sleeve 28 for the lowermost horizontal support member 16 pointing straight upwardly. FIGS. 19A and 19B show an axis E or straight line E that lies in a plane defined by the axes of the uppermost and lowermost horizontal support members 14, 16. In the embodiment of the playyard 10 having no floor 40, the teardrop shape of the uppermost sleeve 26 points straight downwardly and leads into the upper band 36, which in turn leads into the mesh section 34, which in turn leads into the lower band 38, which in turn leads into the point of the lowermost sleeve 28 that engages the lowermost horizontal support member 16. In this embodiment of the playyard 10 with no floor 40, the upper band 36, the mesh section 34, and the lower band 38 are disposed in a common plane, which common plane includes axis E.
