This invention relates to a combined cot and crib especially designed for use in automobiles, and which may be folded into a small package for storing in a. small place and be easily transported from place to place. The cot is adaptable by change of arrangement to open fully and occupy the space which may be defined as the area between the side doors and between the front and rear seats of the automobile. The height of the cot will be approximately the height of the cushion of the rear seat and the net effect will be equivalent to an extension of the rear seat to rear of the front seat. This arrangement will then permit a number of children touse this extended area for sleeping purposes, etc.

An object of this invention is to provide a convertible cot having end legs and intermediate legs and hinged side frame members with the hinges and intermediate legs positioned in offset relation from the lengthwise mid-portion of the side members to cause the intermediate legs to clear the raised floor portion covering the drive shaft of the automobile.

With the above and other objects in view, the invention will be hereinafter more particularly described, and the combination and arrangement of parts will be shown in the accompanying drawings and pointed out in the claims which form part of this specification.

Reference will now be had to the drawings,

wherein like numerals of reference designate corresponding parts throughout the several views, in which:

Figure 12 is a cross-sectional view taken on line |2|2 in Figure 11.

In the illustrated embodiment of the invention, the numeral I8 indicates a convertible cot comprising a jointed frame H and a cover 12 made of flexible fabric.

The frame II is of substantially rectangular form and includes an end section l3, a small in-- termediate section [4 and an end section I5. The end section [3 includes side rails 16 having right-angular hinges i! pivoted thereto. The hinges I! are secured to leg members l8, l8 which are pivotally connected at their mid-portions by a rivet 20.

The small intermediate section It is pivotally secured to the end section I3 by T-shaped hinges 2|. The upright portions 22 of the hinges 2| are secured to leg members 23, 24 which are pivotally connected at their mid-portions by a rigid offset bracket 24 pivotally mounted at 25.

The end section l5 includes side rails it having right-angular hinges I! pivoted thereto. The hinges I! are secured to leg members l8, 18 which are pivotally connected at their mid-portions by a separable wing nut and bolt 26.

The purpose of the removable wing nut 26 is to permit separation of the legs l8 so that in the upfolded position of the cot ID, the legs may be turned over and lie parallel with the upfolded portion it of the side rail (Figures 5 and 6) The leg member 23 of the intermediate leg assembly is continuous. The leg 23 is a two-section leg. The continuous leg 23 is pivotally connected at its upper end to the T-shaped hinges 2!. The two-section leg 23 is made of sections 23 and 23 which are secured in the offset bracket 24. The pivot 25 of the bracket 24 connects the mid-portion of the bracket to: the mid-portion of the continuous leg 23.

The bracket 24 is formed of two plates which are respectively secured to opposite sides of the leg sections 23 and 23 The leg sections are thereby held in offset relation but in the same transverse plane and parallel to each other. The

plates forming the bracket are fiat at the middle and lie on opposite sides of the continuous leg 23. The plates hold the assembled legs in one plane and permit the continuous leg 23 and the two-section leg 23' to swing relative to each other.

The continuous leg member 23 is connected to a hinge 2| by rivets 28 passing therethrough. The upper leg member 23 of the two-section leg 23 is also connected to a hinge 2| by rivets 28 passing therethrough.

The hinges 2| are pivotally connected by pivot pins 30 passing through the side members I6 of the end section [3 and the intermediate section M of the frame H. In straight or upfolded relations, the side members [6, l6 are locked by a transverse pin 3|, which is removable when the cot is changed from one use to another use.

It is to be noted that the removable pin 31 on each side of the frame is removed when' the cot I0 is folded for storage purposes. The removable pins Sl'must normally be used to support the small intermediate section it of the jointed. frame Hinclownfclded as well as in upfolded positions. As shown i, it will be seen that in the upper lace of one rail it of the cot ii are three upright apertures 3a. In the upper face of the other rail is of the cot it are two upright apertures 34' (Figures 2, 10, 11 and 12). Mounted on the cot Isl and secured by the apertures 3t and'34' "is a crib 35. The crib has a tiltable side wall 36 having an upper rail 3? and a lower rail 38. The crib has a stationary side wall l!) having an upper rail 4! and a lower rail s2. The lower rail-42 of the non-tiltable side has three downwardly projecting pins 33 fitting in the apertures 34.

Each end of the upper rail 37 is pivotally secured to the' body of the crib'35 by a screw M and a connecting plate 45 having an elongated slot 48 through which a bolt 47 passes. The connecting plate 45 permits the tiltable side wall 36 to be tilted and locked in the tilted position in relation to the crib by a wing nut 48.

" The tiltable side wall 36 permits this wall to be adjusted to an inclined position to suit the contour of the rear face of the front seat of the automobile. lihis permits a cot of the full distancebetween the front and rear seats to be used at the seat level. This tiltable side wall also permits the cot when coasting in conjunction with the crib to have side walls in an upright position and yet allow for the incline of the front seat.

NVhen the tiltable side wall 35 is swung to the desired angular position, it is locked to the upper end rails 65 of the end walls of the crib by means of the two slotted arms and bolts 4'! and wing nuts 48.

- To 'permit the upfolding of the rail section I5,

I provide'a specific hinge 513 having the hinge leaves bent into angular shape to permit the hinge leaves to contact both sides of a rightan'gular corner of a rail 16 on the cot ID, instead of lying on one fiat surface as usual. It is to be noted that the left half of the hinge 5! has the same angular form as the right hand half and thus in unfolded position, the right half abuts against the left half, limiting the section 15 to swing to an upright position. The hinge 56 makes it possible to fold the adjoining side rail sections I4 and IS on a plane passin through a diagonal line of the rail. Two hinges make it possible to' fold the cot into the right-angular position shown in Figure 6.

The lower rail 38 of the tiltable side wall 38 has pins 5? extending therefrom at opposite ends. The pins 5'? extend into the lower rail 58 of the end walls of the crib. This permits the tilting of the tiltable wall 36. It is to be noted that a support pin 59 is provided in each lower rail 58. The pins 59 extend vertically downwardly into the apertures 34'.

Figure 1 shows grommets 60 positioned in spaced apart relation lengthwise of .the cover l2. A similar set of grommets (Figure 9) BI is positioned in the cover I2 close to the lengthwise bottom edge 82 thereof. Figure 3 shows locl: pins 63 extending. sideways from one of the rails [3. As shown in Figures 1 and 9, it will be seen that the two sets of grommets 3D and BI are in linearly aligned relation. At the opposite side of the cot H! the rail 16 has staples 65 by means of which one lengthwise end of the cover I2 is secured. The object of the double sets of grommets in the cover i2 is for making the cot either narrow or wide for use in automobiles having small or large distances between the front and rear seats. When the set of grommets BI is used, the cot is fully opened to a width that would acsommodatewa fully grown normal person.

Figure 6 shows two holding pins 5 l 52 in spaced apart relation from each. other. A tie rod 53 is pivoted to the end section rail H) by a pin 54. The other end of the tie rod 53 hasa hook shaped end This arrangement makes it possible to connect the tie rod to the pin 5! to secure the right-angular position of the cot shown in Figure 5, or to secure the tie rod to the pin 52 so as to form a reclining back to the cot. In this reclining position the cot may-be used as a beach chair.

It will be noted that the upfolding of one end of the cot results in its occupying a fractional part or" the width of the automobile and thus permits normal occupancy of the rear seat by one or more persons, while at the same time permitting the occupancy of the shortened cot by one or more children. This change is accomplished without tools, as elements utilizedin serving one function are utilized and essential in serving the other function.

As shown'in Figure 9, the combined cot and crib I0 is shown installed in an automobile having a raised floor portion 'l'l covering the drive shaft 12 of the automobile. Figure 9 shows the end leg members IB and the leg members 23, 23' positionedin offset relation from the longi#- tudinal mid-portion of the combined article. This offset relation causes the leg members 23, 23' to clear the raised floor portion H of the automobile 1D.

In accordance with the patent satutes I have described and illustrated the preferred embodiment of my invention, but it will be understood that various changes and modifications can be made therein without departing from the spirit of the invention as defined by the appended claims.

I claim:
