Definitions
- This invention relates to a novel and improved play pen for children and other purposes and more specifically to an improved structure facilitating the opening and closing of the play pen and at the same time securely locking the play pen in an open position.
- Such play pen structures which embody means for folding and unfolding the play pen.
- Such play pens include upper and lower frame members of generally rectangular configuration wh ch are fol-dable along axes bisecting opposing sides. With such a structure, it is important that the play pen when in the open position be securely locked in the open position to avoid injury to an infant or child that may be occupying it.
- Certain of the known structur s generally include pairs of diverging legs on each side thereof, means between the legs and the upper frame sections to support the upper frame sections in a horizontal position and some form of locking means or legs centrally of the bottom sections to limit the downward movement thereof.
- Other known play pens use variations of the foregoing structure, and in general, all of these play pens require the release of several locks or toggle latches order to permit the structure to be folded.
- This invention has as one of its objects an improved play pen wherein the linkages for holding the play pen in an open position secure the pen in such open position and at the same time the locking linkages can be released by a single motion to facilitate folding of the play pen.
- Still another object of the invention resides in the provision of a novel and improved play pen that may be readily and easily opened and securely locked in an open position and which may be quickly and easily folded.
- Still another object of the invention resides in a novel and improved play pen for children and other purposes.
- FIGURE 1 is a perspective view of the improved play pen in accordance with the invention.
- FIGURE 2 is an enlarged side elevational view of the play pen of FIG. 1.
- FIGURE 3 is a fragmentary bottom view of the structure shown in FIGURE 2.
- FIGURES 1 to 3 are diagrammatic views showing an initial step in folding the play pen shown in FIGURES 1 to 3.
- FIGURE 5 is a diagrammatic view of the folded play pen.
- FIGURE 6 is an enlarged fragment ry view in perspective of a portion of the bottom of the play pen showing the locking and unlocking stirrup.
- the play pen in accordance with the invention and as fllustrated by the embodiment shown in the drawings is of rect gular configuration and provided with upper and lower rrarne members joined by a flexible netting such as fabric or the like.
- the play pen support is provided by two sets of legs which are joined to the central portions of the sides of the top frame and diverge outwardly. The lower portions f the legs are pivotally connected to die bottom frame.
- the play pen is held in an open position by four sets of series connected links joining a section of the top frame and adjoining leg and the corresponding section of the bottom frame.
- the linkages are arranged and constructed to coordinate the motions of the top and bottom frames during the folding and unfolding procedures.
- the bottom frames When the bottom frames are in a horizontal plane, they automatically lock the sections of the top frame in a horizontal plane. Furthermore, the weight of a child in the play pen will function to lock the top frame in the open position and once locked the play pen wil remain securely in the open position.
- the links function to automatically unlock the top frame portions, and by further raising the bottom frame sections along the central portion thereof, the entire unit will fold to a storage position. With this arrangement, it is not necessary to release latches individually since all of the latches will automatically release upon raising one side of the bottom portion as described above, and the entire unit can be folded without reaching into the play pen.
- the mattress which usually is employed on the floor of the play pen, need not be removed and can be readily folded along with the play pen in the man er as de scribed above.
- top and bottom frames are generally denoted by the numerals 1b and 11.
- the top frame is formed of two U-shaped sections 12 and 13 with the legs and 12B of section 12 being connected to the legs 13A and 13B of section 13. loinder of the sections is accomplished by U-shaped saddles 14 and 15 with the saddle 14 being pivotally connected at 14A and 143 to the legs 12A and 13A, respectively.
- the saddle i5 is pivotally connected at 15A and 153 to the legs 12B and 13B. 11 this wa the sections 12 and 2.3 of the top frame can be readily folded one relative to the other with the total motion of each section being limited approximately to an angle of 99.
- the bottom frame 11 is formed in effect of two closed loops to and 1'7.
- the loop 36 which is somewhat larger than the loop 17, is formed of two U-shaped sections it? and 19 with the legs 18A and 19A being connected by riveting or other suitable means substantially as shown in FIGURE 3.
- the corresponding legs of the U-shaped sections is and 19 are joined in a corresponding manner.
- the bottom frame section 17 is also formed of two U- shaped portions 2% and 21 with the legs ZiiA and 21A joined to form a rigid structure and the opposite legs of the portions 2i 2f. are similarly connected.
- the bottom sections 16 and 17 are hinged one to the other by a hinge Z2 joining the ends of the legs ldA and 29A.
- the bottom frame sections 16 and 17 carry doors 23 and 24 respectively which rest on the top of the frame sections and are secured thereto by a plurality of brackets such as the brackets 25 as illustrated in FIGURE 3.
- top and bottom frame sections 1 and 11 are joined by a nett' g 26 attached to the frame sections in any suitable rnanner.
- the netting is shown tubular fabric elements 2'7 and 23 which slide over the top and bottom frames 14.? and 11 as illustrated in FIGURES l and 2, though it is apparent that any other suitable means for attaching the netting 26 to the top and bottom frames may be utilized.
- Th leg and linkage assemblies on each side of the play pen in accordance with the invention are substantially identical, and accordingly, only one side will be described in detail.
- the entire play pen is supported by four legs 39, El, 32 and 33.
- the legs 3% and 31 are pivotally attached at 39A and 31A to the saddle 15, while the legs 32 and 33 are similarly joined to the saddle 14. It will be observed that the saddles in each case preferably overlie both sides of the legs joined thereto and provide adequate rigidity without the need for other transverse supporting members disposed between the bottom ends of the legs.
- the legs 3% and 31 diverge outwardly with the leg 36 being pivotally secured at 3GB to an outer portion of the leg 243A of the bottom frame section 17.
- the leg 31 is similarly pivoted at 313 to an outer portion of the leg 313A of the bottom frame section 15. If desired, the bottom ends of the legs may be provided with appropriate wheels'34 or other suitable means.
- the linkage 35 has an upper link 37, an intermediate link 38 and a lower link 39.
- the links 37 and 33 are pivoted one to the other at 46 and include a saddle-type lock 41 which limits motion of the links in an upward direction to a position slightly past alignment or dead center.
- the links may move in an opposite or downward direction virtually to an overlying position when the play pen is closed.
- the upper end of the link 37 is pivoted at 42 to the leg 12B of the upper frame sect-ion 12.
- the link 33 is pivoted at 43 at a point between its ends to the leg 3%).
- the bottom end of the intermediate link 38 is pivoted to the upper end of the link 35*. at 44, and the link 3 is pivoted at its lower end at 45 to a point on the leg ZtBA of the lower frame 17 which is between the hinge 23 and the pivot StiB.
- the linkage assembly 35 is similarly arranged having an'upper link 46, an intermediate link 47 and a lower link 48.
- the link 46 has its upper end pivoted at 49 to the leg 13B of the upper frame 13 and its other end pivoted at 50 to the upper end of the link 47.
- This pivotal connection also includes a saddle lock 51 corresponding to the lock 41 previously described.
- the link 47 is further pivoted at a point between its ends to the leg 31 at 52 and the lower end of this link is pivoted at 53 to the upper end of the link 48.
- the lower end of the link 48 is pivoted at 54 to the leg 18A of the bottom frame section 16.
- the opposite side of the play pen is arranged with similar linkages similarly connected.
- the bottom frame section 16 is further provided with a stirrup 55 firmly secured to the bottom frame section 16 by means of a rivet 56 securing one end of the stirrup to the leg 18A and the pivot pin 22' of the hinge 22.
- FIGURES 4 and5. The operation of the play pen as described above is illustrated in FIGURES 4 and5. Let it be assumed that the play pen in the closed position as shown in FIGURE '5 is to be opened. To accomplish this, the top frame sections 12 and 13 which extend downwardly are manually lifted to a horizontal position. In so doing, the linkages open up and function to spread the legs 30 and 31 and; at the'same time force the bottom frame members 16 and 17 to a horizontal position. This intermediateposition is shown in FIGURE 4. When the play pen has attained the position shown in FIGURE 4, pressure is then exerted downwardly on the stirrup 55 by placing the toe of the foot in the stirrup and pressing downwardly. It will be observed that the links 39 and 48 in moving downwardly will cause the link fid to rotate in -a clockwise direction about the leg 30 and the link 47 in a counterclockwise direction about the leg 31. This.
- stirrup 55 For convenience, only one stirrup 55 has been shown in the drawings, though it is evident that stirrups may be utilized on both sides to avoid the need for turning a play pen around or walking to the other, side in order to open or close it.
