PLAY PEN Filed Oct. 15, 1947 2 Sheets-Sheet 2 RALPH A BANS INVENTOR;

Patented Dec. 20, 1949 UNITED STATES PATENT Claims.

This invention relates to new and useful improvements in play pens for babies and youn children.

An object of the invention is to provide a play pen having a floor, side walls and end Walls; which is readily collapsible; and which when collapsed includes, coupled together, all the parts just enumerated.

Another object is to provide a play pen as above, having an upper part of a side wall lowerable, to facilitate easy reach into the erected play pen.

A further object is to provide a play pen having the advantages already recited, wherein the same includes one or more end gates, a selected one of which may be swung open to obtain access to the play pen by walking into the same.

Still another object is to provide simple and practicable means for locking said lowerable part in normal or raised position, for locking closed the gate or gates provided, and for interlocking the side walls and the end walls at the four corners of the play pen, with such means readily unlockable by the mother or a nurse from the exterior of the play pen but absolutely beyond chance of being unlocked by the child in the play pen.

Still a further object is to provide a floor supporting means which serves when the play pen is erected to hold the floor against sagging at its central portion, and which when the play pen is collapsed will not interfere with compact collapsing thereof.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a matrial part of this disclosure:

Fig. 1 is a perspective view, showing one possible form of play pen according to the invention erected.

Fig. 2 is a plan view thereof on a reduced scale, with the bottom of the play pen turned up and revolved 90 to the right.

Fig. 3 is a considerably enlarged detail view, being a vertical section taken on the line 33 of .Fig. 1.

Fig. 4 is a similar view,'being a vertical section taken on the line 4 =4-of Fig.1.

-Fig. 5-is a top plan view of the play pen, fully collapsed.

Fig.6 is an-end elevation of the thus colla-psed P y P Fig. 7 is an enlarged fragmentary detail view, being a vertical section taken on the line i--l of Fig. 5.

The play pen, according to the present invention, includes a pair of floor sections it and It, a pair of side sections I! and i8, and a air of end sections each including a pair of like gates it and I9 or 2|] and-20'.

The floor section 15 is hinged to the side section H at 22, 22, and the floor section it is similarly hinged to the side section l8 as indicated at 23, 23; said floor sections being hinged together as shown (Fig. 2) at 24, 24. Thus, when the play pen is collapsed, the floor sections l5 and it are able to be folded up inverted-V fashion for finally lying between the side sections ll and 68 as shown in Figs. 5 and 6.

The central portion of the floor l5-ii5 is prevented from sagging by supporting members 25 and 26 (Figs. 1 and 2), each swingable about a pivotal mounting pin 2? or 23, these on the bottoms of the sidesections l7 and it.

When the play pen is erected, said members are arranged at right angles to the meeting lines of the floor sectionslii and I6, so that then the feet 29 and-3i] on ends of the members 25 and it will be beyond the side limits of the play pen, and like feet 3| and 32011 the other ends of said members will be below the floor I 5l 6 near its center. Said feet are of a height such that, with their bottoms on the lawn or other area where the play pen is erectedand with the latter resting on its own four feet 33, 34, and til, the tops of the members 25 and 26'will be at such a height above said area that the floor Id-46 will be sustained parallel therewith.

The members 25 and 26 are pivotally mounted on the pins 21 and 28, so that on collapsing the play pen they may be swung through 99 to he as indicated in broken lines at 25' and 2% in Fig. 2, and as shown in Fig. 6. Otherwise, it would be impossible to arrange the floor sections and it; in the facewisely compact relation shown. in Figs. 5 and 6whe'n the playpen is collapsed.

Forming suitably inbuilt permanent parts of a lower rectangular fra'ine'39 of the side section it are two like vertical posts 3i and 3B. Thus these posts form co'h'tinuations of the length of said section'lB, beyond theportion thereof comprising said lower frame 39, .carrying ,a plurality of spaced vertical "bars such as ordinary wooden dowels 46, and an lipper similar and similarly bar-equipped rectangular fiame ill, the latter hinged td tnelowerrrame 39 as at 42, i2.

Likewise forming suitably inbuilt permanent 3 parts of the side section ll are two vertical posts 4 3 and 55, both alike, and like the posts 37 and 35; said section ii, however, comprising a single rectangular frame 45, also provided with bars such as Wooden dowels, as shown.

This frame 45 is of the same length as the two frames 39 and M of the side section ill, and a height equal to the sum of the heights of said two frames. The post 43 is hidden in Fig. 1, but the same is shown in Figs. 2, 3. 5 and 6.

The tops of said posts 31, 3B, 43 and 44 (see Fig. 1, taken with Fig. 6) are level with the tops of the side sections I! and ill; but the posts 31 and 38 end at their bottoms about level with the bottom of the lower horizontal rail 46 of the lower frame 39, and, similarly, the posts 43 and 44 end at their bottoms about level with the bottom of the lower horizontal rail 41 of the side section I1.

As a result, the vertical rails of said lower frame 39 project below the posts 31 and 38, to provide the feet 34 and 35; and, likewise, the vertical rails of the side section ll project below the posts 33 and 44, to provide the feet 33 and 35.

Each post 31, 38, 43 and 44 is centrally bored throughout its length, as indicated at 48 in Fig. l in the case of the post 31. Such bore through the post .4 is for the reception of a long bolt 49, and such bore through each of the posts 3?. 38, 43 is for the reception of a long pin 5G, 5! or 52. All these three pins are alike, each having a countersunk head at its upper end as shown in Fig. 3 in the case of the pin 52, where such head is marked 53.

By means including said bolt and pins, the side section H at one of its ends is vertically pivotally connected to an end of the end gate l9, and at its other end is similarly connected to the end gate 20, and the side section it at one of its ends is similarly connected to the end gate !9 and at its other end is similarly connected to the end gate 20; the gates l9 and I9 being hinged together as at 54, 54, and the gates 20 and 2!) being hin ed together (see Figs. 5 and 6) as at 55, 55.

For coaction with the pin 52, the gate 59 carries at its top a plate 56, secured to said gate by a rivet 5! and projected over the top of post 43. As shown in Fig. 3. the plate 56 has a conical aperture, in line with the bore through said post. for seating the countersunk head 53 of said pin in such manner that said head is inaccessible for removing the pin by upward grasp of said head. On the bottom of the gate l9, secured thereto as at 55, is a plate 59 like the plate 56 except that the plate 55, where it projects under the post 43, is merely cylindrically apertured for easy endwise movement therethrough of the lower end of the pin 52.

It will be noted from Fig. 3 that the lower end of the pin 52 proiects below the plate 59, to the extent of about half the height of the foot 33.

The arrangement just described provides a corner locking for the erected play pen, as between the side section I! and the gate is, such that the child in the play pen cannot break such lock. as to do so he must lift up the top of the pin 52, which he cannot do. However, his mother or nurse can easily break the lock. whenever desired. simply by using her foot to lift the bottom of pin 52 such a slight distance as to raise its head 53 a trifle above the plate 56. as indicated at 53' in Fig. 3, and so to dispose said head for easy finger grasp to wholly withdraw the pin.

A precisely similar arrangement is provided at the corners of the play pen occupied by the posts 3'! and 38. Thus, a plate 60, corresponding to the plate 56, is on the top of the gate i9, and a plate 5!, corresponding to the plate 59, is on the bottom of said gate, while with these plates 65 and (ii the pin 5| is used; and a plate 62, corresponding to the plate 56, is on the top of the gate 225', and a plate 63, corresponding to the plate 59, is on the bottom of said gate, while with these plates 62 and 63 the pin 50 is used.

However, in the case of the plates BI and 62, the means by which each of said plates is connected to the gate l9, such means being a rivet such as shown in Fig. 3 at 51, is a rivet which is not headed over so tightly as to preclude rotational movement of the plates relative to said gate [3; thereby to permit collapsing of the play pen as shown in Figs. 5 and 6.

For the remaining corner of the play pen, that at the location of the post 44, a withdraw-able pin is not used, but, instead, the bolt 49, as best shown in Fig. 4; thus to provide a permanent pivotal connection, by the aid of plates 54 and 65, respectively similar to the plates 56 and 55, between the end gate 25 and said post 44, and. consequently, between said gate and the side section ll.

The plate 65, at the bottom of the gate 25, is exactly like the plate 59, and the plate 54, at the top of said gate, differs from the plate 56 in only one particular, that is, the aperture through the plate 64 is merely a cylindrical one for taking the shank of the bolt 49. The bottom portion of said bolt is threaded, to which threaded portion of the bolt is applied a nut and lock=nut couple as indicated at 66 in Fig. 4.

For a purpose analogous to that mentioned in the second paragraph preceding, the rivet by which each of said plates 64 and 65 is connected to the gate 20 is not headed over so tightly as to preclude rotational movement of these plates relative to their gate when the play pen is collapsedJ When the play pen is erected as in Fig. 1, a child placed therein is unable to break the look at any of the four corners thereof, as he cannot remove the bolt 49, nor lift free any of the pins 50, 5| and 52. Nevertheless, whenever the mother or nurse desires, a side portion, the upper frame 5! of the side section i8, may be readily lowered; or an end gate readily opened; or the play pen readily collapsed.

For easy reach toward the child, said upper frame 4| may be lowered, on the hinges 42, as soon as the pins 50 and 5! are first slightly raised by upward thrust on their bottoms and then pulled upward by grasp at their topsas previously explained.

For opening either or both of the gates l9 and I9, it is merely necessary to withdraw the pin 5| and for opening either of the gates 29 and 25, it is merely necessary to withdraw the pin 55.

After withdrawing merely the pins 55 and 52, it is simple and easy to collapse the play pen to dispose its various parts as shown in Figs. 5 and 6; by swinging the gates 2B and 20 as a single structure about the bolt 49 in a counterclockwise direction as per the arrow El of Fig. 1, swinging the gates 20 and 25 about the mum in a counterclockwise direction as per the arrow as of Fig. 1, and then moving the sections I! and I 8 parallelly toward each other, this last causing the floor sections l5 and It to rise inverted v fashion. When said floor sections become disposed'as in Figs. 5 and 6, the members 25 and 26 are rotated through to dispose them as shown in Fig. 6,

that is, in their positions indicated at broken lines at 25 and 26' in Fig. 2, and so parallel with the side sections I1 and I8.

The bored posts 31, 38, 43 and 44 are important, as, with the bolt 49 inside the post 44, the posts 31, 38 and 43 act as shields to prevent the child in the play pen from reaching the shanks of a pin 50, Si or 52 and there lift such a pin to break its look at its corner of the play pen.

The plate pairs BI] and BI, and 64 and 65, or equivalents, are important; as otherwise, and as already mentioned, the end gates l9, I9, 20 and 20' could not be arranged, when the play pen is collapsed, in that desirable close parallellism with the side sections l1 and 4-8 illustrated in Figs. and 6.

The only separable parts are the pins 50, 5! and 52. Yet these are so long that there is no chance of loss or inadvertent misplacement thereof, as would be the case were short pins used; in which latter case chains for tethering such pins would suggest themselves. The pins 50, 5| and 52, however, will be dropped into their bores through the posts 31, 38 and 43, as soon as the play pen is collapsed, as illustrated in Fig. 'I in the case of the post 38 and its pin 5!); there safely to remain until the play pen is again desired to be erected.

While I have illustrated and described the preierred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
