8 Claims.
This invention relates to an improved play pen for infants.
In the prior art portability of play pens has been generally accomplished by providing a collapsible structure. There are many varieties of collapsible play pens. Collapsibility is often obtained by making the base in two parts which are hinged to each other, and by hingedly mounting two of the four walls to the base member. Various expedients have been employed for constructing the remaining two walls so that the structure as a whole will be collapsible. However, it has been found that in carrying the collapsed structure from place to place, the base and wall members tend to unfold, thereby causing great inconvenience and oftentimes requiring the assistance of another person when the collapsed structure is moved from place to place.
A further objection to the usual collapsible play pen is thatl the two piece hinged base in combination with the usual means by which the walls are secured to each other, do not provide a rigid structure which can be moved with facility from place to place within a room without collapsing the same.
In other words, the advantage of portability provided by the usual collapsible play pen, is offset in large measure by the inconvenience involved in handling the collapsed structure, Furthermore, the collapsible features detract from the rigidity of the play pen when opened up for use.
It is an object of my invention to provide an improved play pen which combines the advantages of portability with ease in handling the collapsed or demounted structurey and which also provides, when fully assembled, a comparatively rigid structure. In this connection, I have provided a play pen in which the base also serves as a carrying case, the several parts of the structure being demountably mounted on the base, and being of such dimensions that they can be entirely received Within the carrying case which is formed from the base.
A further object is to provide a play pen which is improved with respect to sanitation and safety. In this connection, I have provided a play pen which is in the form of a fabric enclosure which is supported on demountable members. Thus, a construction is provided in which the infant comes in contact only with the fabric enclosure. The fabric enclosure may be washed as often as necessary, thereby providing a play pen which is much more sanitary than the usual collapsible wooden structure. Furthermore, the fabric en closure prevents the infant from picking up slivers from the Wooden members. Also, there are fewer rigid parts against which the infant can fall and receive bumps.
A still further object is to provide in combination with a portable play pen a removable and demountable canopy or sunshade. Thus, the play pen can be set up out of doors and means are provided for protecting the infant from sun or wind.
Other objects, features and advantages will become apparent as the description proceeds.
With reference now to the drawings in which like reference numerals designate like parts- Fig. 1 is a perspective view of a preferred embodiment of my invention in fully assembled form;
Fig. 2 is a perspective view of the playpen in portable form, the base serving as a carrying case for the various demountable parts;
Fig. 3 is a top view of the play pen as shown in Fig. 1;
Fig. 4 is a vertical section taken along line 4 4 of Fig 3, the dotted line showing the base in folded position;
Fig. 5 is an enlarged section taken along line 5-5 of Fig. 3, showing the manner inwhich the corner post is mounted on the base;
Fig. 6 is a section taken along line 6 6 of Fig. 3;
Fig. '7 is a detail section view taken along line 1-1 of Fig. 6;
Fig. 8 is a detailed enlarged plan view of the corner construction;
Fig; 9 is a section taken along line 9 -9 of Fig. 8;l
Fig. 10 is a View similar to Fig. 9, but showing the manner in which one of the canopy supports is mounted on the corner post; and
Fig. 1l is a section taken along line Hf-ll of Fig. 10.
The reference numeral iii designates generally the base of the play pen, upon which is mounted an enclosure I6. A canopy i1 is removably mounted on certain of the structural members of the enclosure I6, as will be hereinafter pointed out.
'Ihev base I5' comprises two box-'like members i8 and i9, which are secured to each other by hinges 20, as shown in Figs. 3 and 4. Each of the box-like members is approximately twice as long as it is wide, so that the two` members together form a substantially square base'. As shown in Figs. 4 and 6, the box-like members comprise supportingv surfaces 56 and flanges 5i.
In operative position, flanges will rest on the ground or the floor and maintain the supporting surface out of contact therewith. The hinges are secured to the edges of the abutting pair of flanges, so that the box-like members may be folded together to form a carrying case, as shown in Fig. 2. In this position of the parts the corresponding ilanges 5| of each box-like member abut each other at their edges, thereby forming the top, bottom and end walls of the carrying case, while the supporting surfaces 50 form the side Walls thereof. Suitable handles 2l may be provided to facilitate the carrying of the base, and a suitable latch 52 may be provided to keep the parts in closed position.
The enclosure I6 comprises a fabric enclosure 22 and a supporting structure formed from corner pos-ts 28 and horizontal rails 29. The fabric enclosure 22 comprises a bottom wall 23 and side Walls 24, which may be made of any suitable fabric such as canvas. In the embodiment shown, the upper portions of the side walls 24 are made of netting 25.
The fabric enclosure is provided with four sleeves 26 at the vcorners thereof to receive the corner posts 28. Four sleeves 21 are lprovided along the upper edges of the side walls 24 to receive the horizontal rails 29. Thus, the fabric enclosure 22 may be supported from the horizontal rails 29 and each of its side walls 24 will be tensioned in a horizontal direction between the corner posts 28.
The joints 34 between the horizontal rails 29 in the corner posts 28 are shown in Figs. 8 and 9. The end portions of the horizontal rails are slabbed as indicated by the reference numeral 32,
and these slabbed ends t into slots 33 which exl vtend downwardly a short distance from the ends of the corner posts. As shown in Fig. 8, there are two slots in each corner post. The rails are held against the end of the slot by means of a spring strip 35 which is secured Iby one or more screws 36 to the wall of the slot. The spring strip is biased outwardly so as to engage the upper surface of the rail and hold it in position. Thus, the rail may be slid downwardly into the slot without flexing the corner post, and the rail will be automatically locked into position. To remove the rail, the lower end of the spring strip is depressed with the finger to clear the end of the rail, and then the rail may be lifted upwardly and removed from the slot.
In assembling the parts, the base is first opened up from its carrying case position, as shown in Fig. 2, and as shown in dotted lines in Fig. 4, into its -operative position. The corner posts 28 and the horizontal rails 29 are then inserted within the sleeves 26 and 21, respectively. The corner posts are then positioned in the bores 3|. The
. joints 34 are then assembled, by slipping the slab ends 32 of the rails into the slots 33 of the corner posts to complete the assembly. It is desirable to dimension the fabric enclosure 22 so that the distance between the sleeves 26 correspond rather closely to the distance between the corner posts. Thus, the side walls 24 of the enclosure act as tension members and prevent the corner posts from spreading. This feature is particularly desirable inasmuch as the base I5 is formed of two hinged members, for the reason that the tension on the side walls will prevent the base from buckling when the play pen is lifted and moved from place to place. The joint construction 34 permits the parts to be assembled even though the tension of the side walls might be suflicient -to make it very difficult to bend the corner posts outwardly, as would -be necessary if merely a socket were provided.
In the event that it is desired 4to use the play pen out of doors, a canopy I1 is provided which may serve as a sunshade or as a Wind breaker. The canopy comprises a, supporting structure formed of a pair of bent arms 31, and a cross bar 38. These may be secured to each other by a joint construction 44 similar to the joint construction 34 which has already been described. The bent arms and the cross bar support a fabric sun 'shade 39 which is formed with sleeves 40 for the bent arms 31, and with Ia sleeve 4| for the cross bar 38. The fabric shade is extended downwardly to form a back flap 42, as shown in Fig. 6, which may be secured `to the base I5 by suitable clips 43.
The lower ends of the bent arms 35 terminate in metal sleeves 45 which are adapted to -t over the upper ends of two of the corner posts 28. As 'shown in Fig. 10, the sleeve 45 may be secured to the bent arm 31 by one or more rivets 46'. The sleeves may also carry one or more projections 41 which t into the slots 33 of the lcorner posts, thereby maintaining the bent arms in proper alnement.
It will be seen that the canopy construction is demountable, in the same manner as the enclosure construction, and may be readily mounted over any wall, and on any pair of corner posts of the enclosure. The back flap 42 serves as a wind breaker, but of course this would not be necessary if the side walls 24 of the fabric enclosure were formed entirely from canvas, instead of partially from netting, as shown.
All of the structural members, both of the canopy and of the enclosure, are of such dimensions that they can be readily placed within the boxlike members 8 and I9, and carried from place to place in the carrying case formed therefrom. The fabric enclosure 22 and the fabric shade 39 will also t within the carrying case.
The construction herein provided not only adapts itself to convenient portability, but presents an attractive article, both when fullyassembled and when packed away in its carrying case. The exterior surfaces of the carrying case may be decorated but the infant is protected from contact with any painted decorations due to the provision of the fabric enclosure 22. The latter may be washed and maintained in sanitary condition.
