Definitions

  • the present invention relates to collapsible structures for child use such as a collapsible baby bed, infant playpen, children play tent and the like.
  • the present invention also relates to methods of collapsing and expanding the structure.
  • Collapsible structures are commonly used in collapsible baby beds, infant playpens, cribs, playhouses, tents, pavilions, shelters, sun shields, etc.
  • U.S. Patent No. 6,035,466 discloses a collapsible baby bed which includes a fabric cover covering a collapsible tubular frame.
  • the frame includes a plurality of links which are coupled by a resilient cord such that when in use, the bed may take the form of a conventional crib or playpen.
  • the links When the links are decoupled, the bed can be folded into a collapsed structure for storage or transport.
  • U.S. Patent No. 5,363,521 discloses a collapsible playpen having a pair of spaced apart articulated end frames, wherein the end frames are separated by articulated upper and lower rails.
  • the end frames and rails are constructed so that the playpen is collapsed by folding the lower rails to draw lower portions of the end frames together and simultaneously rotating the upper portion of the opposing end frames away from each other such that the distance between the upper portion of the end frames is greater than the distance between the lower portion of the end frames.
  • U.S. Patent No. 3,810,482 discloses a collapsible tent structure in which both sidewalls, the rear wall and top are supported by nearly identical subframe assemblies, each of which has a length of stretchable cord fastening the ends of its jointed diagonally extending struts together.
  • the struts of each subframe assembly are pivotally attached at their adjacent ends to a stop-forming connector at the intersection of the diagonals for foldable movement in one direction into side-by-side relation with one another while such connector limits their unfolded position to one in which they bear an angular relation of over 180° and less than approximately 220° to one another which position is maintained by the tension in the stretchable cord interconnecting the remote ends thereof.
  • the cord preferably is reeved through marginal hems bordering the frame-supported walls thus defining a unitary foldable tent assembly.
  • the frame itself comprises the four more or less identically constructed subframe assemblies pivotally interconnected to one another at their common corners together with the connectors for accomplishing the latter.
  • U.S. Patent No. 4,944,322 discloses another collapsible tent structure wherein a plurality of pole clusters is utilized.
  • Each pole cluster has three poles which form an inverted Y-shape, the poles being loosely connected at the center of the inverted Y so that each of the arms may articulate relative to each other.
  • the poles forming the two arms of each inverted Y extend to the ground and the poles forming the stems of each Y extend upwardly and are connected to each other at the top of the structure.
  • a foldable membrane is provided which is connected to both ends of each pole by a clip whereby a foldable tent structure is provided which may be assembled and disassembled repeatedly without separating the foldable membrane from the poles.
  • a collapsible structure including a first frame member defining a base of the structure and a second frame member defining a top of the structure.
  • a piece of foldable material is attached to and extends between the first and second frame members.
  • a plurality of foldable frame supporters is mounted on the piece of foldable material whereby folding of the frame supporters drives the first and second frame members towards a superimposed and collapsed position, and unfolding of the frame supporters drives the first and second frame members towards spaced apart and expanded positions.
  • Another piece of foldable material covers the first frame member.
  • the collapsible structure can also include hinge mechanisms provided on the first and second frame members for folding the collapsed and superimposed first and second frame members.
  • the hinge mechanism can include a first pair of hinges provided on the first frame member, and a second pair of hinges provided on the second frame member.
  • each of the foldable frame supporters can include a first section and a second section hingedly connected to the first section.
  • the first and second sections can be configured to abut against each other when folded and to remain in an aligned or colinear relationship when unfolded.
  • first and second frame members can be in generally parallel and vertically spaced relationship and the plurality of foldable frame supporters are in a generally upright position when the structure is in the expanded position.
  • the collapsible structure can further include a collapsible hood member attached to the second frame member for at least partially covering the open top of the structure.
  • a collapsible child play enclosure which comprises a plurality of frame assemblies, each of which includes a plurality of frame segments and a plurality of hinges connecting adjoining frame segments.
  • the hinges are constructed and arranged to provide movement of the frame assemblies between assembled and collapsed positions.
  • a piece of foldable material is secured to the frame members to enclose an interior space within the frame assemblies when in the assembled position, the frame segments of said frame assemblies are superimposed on one another in the collapsed position and can be folded into a compact state.
  • a method for expanding and collapsing a structure intended for use by a child which comprises assembling the structure with an enclosure for a child by a plurality of segments incorporating snap-lock hinges; providing a flexible covering on the structure, selectively assembling and collapsing the structure by locking or unlocking the hinges.
  • the said hinges are selectively locked and unlocked by (1) aligning the segments of the structure connected by the hinges and (2) to lock the structure pivotably moving the segments out of alignment to collapse the structure to a folded condition, and when the segments are in the folded condition, they are superimposed on one another to provide a flat condition for the structure which can then be folded at the hinges to make the structure more compact.
