Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] This application is a continuation of U.S. patent
application Ser. No. 13/960,101, filed Aug. 6, 2013, which claims
priority to U.S. Provisional Patent Application No. 61/680,471,
filed on Aug. 7, 2012, which are hereby incorporated by reference
in their entirety.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates generally to a foldable child
enclosure, such as a play yard, playpen, or crib apparatus, and,
more particularly, to a clamp for attaching the enclosure to a
frame structure.
[0004] 2. Description of Related Art
[0005] Foldable play yards, playpens, and crib devices are
well-known. See e.g., U.S. Pat. No. 4,811,437 for a "Foldable
Playyard" to Dillner, et al. Foldable enclosure and crib devices
are generally lightweight and, when collapsed, form a fairly
convenient compact package for easy carrying. In many existing
foldable play yards, a bed frame structure consists of upright
tubes that form the frame of the bed structure and fabric sheets
attached between the tubes to form the enclosure walls.
[0006] In existing foldable playpens, typically an enclosure member
such as a rectangular fabric piece includes sleeves to be pulled
over the upright tubes to form taut stretched walls between the
tube members. Alternatively, the fabric member may be attached to
the tubes with fastening members such as a screw, pins, nails, or
staples. The posts support the fabric member and hold it taut to
form the walls of the enclosure. Systems for fastening a fabric
enclosure member to an upright tube of a foldable playpen are also
known in which the fabric member is held within the tube and
extends from the tube through a longitudinal slit. For example, a
positioning post mounted along the edge of the fabric member may be
inserted in the upright tube. In this case, the attachment
mechanism may be enclosed within the tube structure. However, such
systems for affixing a fabric member to the frame do not provide a
secure and aesthetically pleasing connection. Accordingly, these
connections also do not inspire confidence for parents that the
wall structure is secure and will effectively hold the child within
the enclosure. Furthermore, presently available fastening
mechanisms often cause the enclosure member to stretch or tear when
the playpen structure is folded or unfolded reducing the durability
of the child enclosure structure.
[0007] Accordingly, there is a need for a system and method for
attaching a fabric enclosure member to the frame structure of a
child enclosure apparatus. The attaching system should provide a
secure and permanent connection between the elements that does not
stretch or lose structural integrity following prolonged use. The
connection should also be sleek, attractive, and should not include
external connection elements, such as screws, pins, nails, or
staples, that could injure a child. In addition, the system for
connecting the fabric member to the post should form a dependable
and strong connection which maintains its integrity even following
prolonged uses.
SUMMARY OF THE INVENTION
[0008] The foldable child enclosure apparatus of the present
invention achieves these goals by attaching the edge of the fabric
member in the interior channel within the upright post of the
enclosure frame. More specifically, the attaching mechanism
includes mounting the edge of the fabric enclosure to a piece which
is inserted in the post. The piece is maintained within the post by
inserting a second locking piece to form an engagement which
counteracts forces seeking to remove the fabric from the attaching
mechanism. The fabric member extends outward from the post through
a longitudinal slit extending longitudinally along the length of
the post. In this manner, the attachment mechanism is recessed
within the post reducing the risk that a child will be injured by
the attachment mechanism, such as would occur with an external
mechanical fastener. The attachment mechanism is also visually
appealing and can be folded and unfolded many times without
stretching or tearing the fabric member. Finally, the attachment
mechanism provides strength and stability sufficient to maintain
the structural stability of the enclosure walls during normal
use.
[0009] A foldable play yard apparatus is provided. The play yard
includes a frame having a plurality of upright posts. The posts
have a top, a bottom, and a clamp connected to at least one
longitudinal side of the post. The play yard further includes a
flexible enclosure having a plurality of edges inserted in the
clamps to form walls between the upright posts. The clamp includes:
a housing having an opening for receiving the edge of the enclosure
and defining an interior channel within the housing; a flag piece,
which is positioned in the interior channel of the housing,
connected to the edge of the enclosure; and a locking piece
positioned across the interior channel from the flag piece. A
frictional engagement between the locking piece and the flag piece
maintains the flag piece and the edge connected thereto within the
interior channel.
[0010] According to a further aspect of the invention, a method for
attaching an edge of a sheet to a clamp is provided herein. The
method includes providing a clamp which includes an interior
channel accessible through a longitudinal opening. The method
further includes the steps of attaching the edge of the sheet to a
flag piece; inserting the flag piece and edge of the sheet into the
interior chamber, such that the sheet extends outward from the
longitudinal opening of the clamp; and inserting a locking piece in
the interior cavity to establish a frictional engagement between
the flag piece and locking piece.
[0011] According to a further aspect of the invention, a method of
constructing a play yard apparatus is provided herein. The method
includes the step of providing a frame, including a plurality of
upright posts having a top, a bottom, and longitudinal sides
extending therebetween, and a flexible enclosure having a plurality
of flexible sheets and a plurality of edges. The method further
includes the steps of: attaching a clamp along a longitudinal side
of one of the upright posts, the clamp comprising a longitudinal
opening and an interior channel; attaching a flag piece to the
longitudinal edge of the flexible enclosure; inserting the flag
piece into the interior channel of the clamp, such that the edge of
the enclosure extends through the longitudinal opening of the
clamp; and inserting a locking piece into the interior channel. A
frictional engagement between the locking piece and the flag piece
maintains the flag piece, locking piece, and edge of the enclosure
within the interior channel.
[0012] These and other features and characteristics of the present
invention, as well as the methods of operation and functions of the
related elements of structures and the combination of parts and
economies of manufacture, will become more apparent upon

"bottom", "lateral", "longitudinal", and derivatives thereof shall
relate to the invention as it is oriented in the drawing figures.
However, it is to be understood that the invention may assume
various alternative variations, except where expressly specified to
the contrary. It is also to be understood that the specific devices
illustrated in the attached drawings, and described in the
following specification, are simply exemplary embodiments of the
invention. Hence, specific dimensions and other physical
characteristics related to the embodiments disclosed herein are not
to be considered as limiting.
[0021] With reference to FIGS. 1-2B, a foldable enclosure apparatus
10, configured in the form of a play yard or playpen, is
illustrated. The apparatus 10 is portable and, as such, is
foldable, closable, or collapsible for easy transition between
opened and deployed positions. The apparatus 10 includes a frame 12
connected to a flexible enclosure 14 having one or more fabric
sheets that forms the walls 16, 18, 20, 21 of the playpen. The
sheets may be formed from any suitable material that is flexible
enough to be folded but is sufficiently strong to avoid tearing,
puncturing, or stretching during prolonged use.
[0022] The frame includes eight upper arms 22, 24, 26, 28, 30, 32,
34, 36, four upper corner assemblies 38, 40, 42, 44, and four
stiffening members 46, 48, 50, 52. The frame 12 further includes
four generally vertically disposed upright posts 56, 58, 60, 62. To
avoid redundancy, only a portion of the frame 12 will be described
in detail. All other like structures of the frame 12 are configured
in the same manner. The upper arm 22 is pivotally connected to a
corner and to the stiffening member 48 through any well-known
mechanical connection such as a rivet. The remaining upper arms are
arranged in a similar fashion.
[0023] The upright post 56 includes a bottom end 64, and a top end
68, connected to a respective upper corner 38. The upright post 56
may pivot or tilt outwardly and, at the same time, pull the upper
corner assemblies outwardly or apart from one another. In one
non-limiting embodiment, the upright post 56 has a generally
L-shaped cross-section with two sides 70, 72 extending outward from
a central portion 74. Clamps 76 connected to the sides of the
upright post 56, extend longitudinally along each side 70, 72 of
the post 56. The clamps 76 are adapted to hold and retain the
flexible enclosure 14 to the post 56.
[0024] The enclosure 14 has a generally rectangular or square shape
formed from four connected sheets that, when connected to the
upright posts 56, 58, 60, 62 of the frame 12, become the walls 16,
18, 20, 21 of the apparatus 10. The enclosure 14 has four vertical
corners 80, 82, 84, 86 that correspond to the upright posts 56, 58,
60, 62 of the frame 12. Each vertical corner 80, 82, 84, 86
includes two edges 88, 90. Each edge 88, 90 is adapted to be
received within the clamp 76, 78 of the respective post 56, to
support the enclosure 14 by providing structural stability for the
walls 16, 18, 20, 22. The enclosure 14 may be formed from any
suitable flexible material that is capable of being folded or
rolled, such as natural fabrics or synthetic polymer fabrics,
including but not limited to nylon, polyester, and the like. The
enclosure 14 may be manufactured from a plurality of sheets that
are separate from each other when connected to the frame 12 of the
apparatus 10 or may be formed from a single sheet that is folded to
form the plurality of walls 16, 18, 20, 21. In certain embodiments,
central portions of the sheets of the enclosure 14 may be formed
from a softer, mesh material (not shown) allowing the child to look
through the walls to see objects outside of the enclosure.
[0025] The enclosure may further include coverings 92, 94, 96, 98,
for covering the upper arms 22, 24, 26, 28, 30, 32, 34, 36 of the
frame and for providing additional structure stability for the
walls 16, 18, 20, 21 of the apparatus 10. The enclosure 14 may
further include a base pad or mattress 100. Side padding (not
shown) may also be placed around the interior of the play yard for
added protection of a child placed on the pad or mattress 100.
[0026] With reference to FIGS. 3 and 4, the clamp 76, 78 for
connecting the edge 88 of the enclosure 14 to the upright post 56
is illustrated. Once again, to prevent redundancy, the structure of
only one clamp structure is described herein. However, it is
understood that an identical clamp is included on each side of each
upright post. Accordingly, in one non-limiting embodiment, the
apparatus 10 of the present invention will include eight clamps for
securing the enclosure 14 to the four respective posts 56.
[0027] The clamp 76 includes a u-shaped housing 110 having a
proximal arm 112 and a distal arm 114. As used herein, "proximal"
refers to the portion of the clamp nearest the upright post.
"Distal" refers to the portion of the clamp farthest away from the
upright post. The arms 112, 114 are attached together at a hub 116
and extend in an outward direction to define a slit like opening
118 at an opposite end of the housing from the hub 116. The slit
like opening 118 extends longitudinally along the length of the
post 56. The proximal arm 112 is connected to the side 70 of the
upright post 56. The housing 110 may be integrally formed with the
upright post 56, such that the side 70 of the post forms the
proximal arm 112 of the clamp housing 110. Alternatively, the clamp
76 may be a separate structure attached to the post 56 be
conventional means such as fasteners or adhesives. The space
between the arms of the housing defines an interior channel 120
adapted to receive and hold an edge 88 of the enclosure 14. The
edge 88 extends from the clamp housing 110 through the slit opening
118. As previously described, the edges 88 form the walls (not
shown in FIGS. 3 and 4) between adjacent upright posts 56.
[0028] With continued reference to FIGS. 3 and 4, in one
non-limiting embodiment, a flag piece 130 is attached to each edge
88 of the enclosure 14. The flag piece 130 may be connected to the
edge 88 of the enclosure 14 by any conventional connector 131, such
as stitching, fasteners, or adhesives. The flag piece 130 is
adapted to be retained within the clamp housing 110 and,
specifically, to be positioned adjacent to the distal arm 114. The
flag piece 130 has a wider bulbous end 132 which corresponds in
shape to the back portion of the clamp, nearest the hub 116. A
narrower end 134 of the flag piece 130 extends from the bulbous end
132 and corresponds to the shape of the distal arm 114 of the clamp
housing 110. The narrower end 134 of the flag piece 130 may further
include a projection portion 136 and a recessed portion 138. In one
non-limiting embodiment as depicted in FIGS. 3 and 4, the
projection portion 136 is located nearest to the opening 118 of the
housing 110 and the recessed portion 138 is located in the interior
of the clamp housing 110 between the projection portion 136 and the
wider bulbous end 132. However, it is understood that the
orientation of the projection portion 136 and recessed portion 138
may be reversed, such that the recessed portion 138 is positioned
nearest to the opening 118.
[0029] The flag piece 130 may also include a notch 140 located near
the opening 118 of the housing 110 that is configured to receive a
lip 122 extending from the distal arm 114 of the housing 110. The
connection between the notch 140 and lip 122 maintains the flag
piece 130 within the housing 110 and resists any force applied to
the edge 88, such as, if a child pushes against the wall.
[0030] The clamp 76, 78 further includes a locking piece 150
positioned adjacent to the proximal arm 112 of the housing 110. The
locking piece 150 also includes a projection portion 152 and a
recessed portion 154 oriented to oppose the projection portion 136
and recessed portion 138 of the flag piece 130. More specifically,
in contrast to the configuration of the flag piece 130, the
recessed portion 154 is located nearest to the opening 118 of the
clamp housing 110 and the projection portion 152 is located within
the clamp housing 110 across the interior cavity 120 from the
recessed portion 138 of the flag piece 130. The locking piece 150
may further include a semicircular rib 156 extending from a
proximal side 158 of the locking piece 150 and adapted to be
retained within a corresponding notch 124 in the proximal arm 112
of the housing 110. The rib 156 and notch 124 effectively hold the
locking piece 150 in place within the clamp housing 110 and resist
force which acts to pull the edge 88 from the clamp 76.
[0031] When inserted within the clamp housing 110, the flag piece
130 and the locking piece 150 further define the shape of the
interior channel 120, which extends from the clamp opening 110 to
the bulbous end 132 of the flag piece 130. In one non-limiting
embodiment, the interior channel 120 is curved or hook-shaped.
Thus, the edge 88, maintained within the clamp 76, follows a curved
or hook-shaped path through the channel 120. More specifically, the
edge 88 is adapted to be retained within the interior channel 120,
held in place by a frictional engagement between the edge 88,
locking piece 150, and flag piece 130. The edge 88 exits the clamp
76 through the slit opening 118 extending longitudinally along the
length of the upright post 56. The locking piece 150 and/or flag
piece 130 may also include structure for biasing the edge 88 as it
exits the clamp housing 110 at the housing opening 118, such as to
direct the sheet in the direction of the respective enclosure wall.
For example, as shown in FIGS. 3 and 4, the locking piece 150 may
include a flange 160 located near the housing opening 118, for
directing the curvature of the edge 88 as it exits the clamp
housing 110. The end of the flag piece 130 may also include a
similar curved end structure 142 for supporting the curvature of
the fabric. By biasing the fabric in this way, a more aesthetically
pleasing connection between the post 56 and enclosure 14 is
created. Such a connection prevents the material of the enclosure
14 from bunching up, prevents unsightly twisting or folding, and
which creates a flat and taut fabric wall for each side of the
playpen or child enclosure apparatus, which inspires confidence in
parents that the apparatus 10 is safe and secure.
[0032] With reference to FIGS. 1-4, the connection between the
enclosure 14 and the post 56 is established according to the
following steps. The flag piece 130 is connected to the edge 88 of
the enclosure 14, as described above, with an adhesive or a
mechanical connection such as stitching. The flag piece 130 and
attached edge 88 are then inserted to the interior channel 120
clamp 76 through the housing opening 118. Once inserted within the
clamp 76, the bulbous end 132 contacts the back portion of the
housing 110 adjacent to the hub 116 and the narrower end 134 is
positioned adjacent to the distal arm 114 of the housing 110. If
present, the notch 140 is aligned with the lip 122 at the end of
the distal arm 114 to securely maintain the flag piece 130 within
the clamp housing 110. The edge 88 may be adjusted to ensure that
there are no areas where the fabric is bunched up and that it exits
the clamp with a taut, aesthetically pleasing appearance. The
locking piece 150 is then inserted into the clamp housing 110
through an opening at the top end 68 of the post 56. The locking
piece 150 slides in a downward direction through the clamp housing
110 to establish a frictional engagement with the edge 88 and flag
piece 130. Thus, the pieces 130, 150 align such that the projection
portion 152 of the locking piece 150 is positioned across the
interior channel 120 from the recessed portion 138 of the flag
piece 130 and the recessed portion 154 of the locking piece 150
across from the projection portion 136 of the flag piece 130. If
present, the projecting rib 156 of the locking piece 150 is
inserted within the corresponding notch 124 of the proximal arm
112. In this manner, the locking piece 150 exerts force against the
edge 88, effectively maintaining the edge 88 within the locking
piece 150 and ensuring that the walls of the child enclosure
apparatus are taut.
[0033] Once the enclosure edges 88 are securely inserted into the
clamps 76, the vertical corners 80, 82, 84, 86 are placed over the
upright posts 56, 58, 60, 62 to cover the openings of the posts and
to prevent the fabric edges from being removed from the posts. At
this point, the coverings 92, 94, 96, 98 can be folded over the
horizontal arms 22, 24, 26, 28, 30, 32, 34, 36 of the frame 12 to
prevent the child from being injured by the joints between the arms
22, 24, 26, 28, 30, 32, 34, 36 and the stiffening members 46, 48,
50, 52. The user may also install lower corners 102, 104, 106, 108
to the bottom of the upright posts 56, 58, 60, 62, which function
as feet for elevating the apparatus off the ground. At this point,
the apparatus 10 is fully assembled and ready for use. In addition,
an upper edge of the enclosure 14 may be connected to the upper
