To all whom it may comem:

Be it known that I, DONALD W. Rrormnns, a citizen of the United States, residing at San Jose, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Folding Cots; and I. do declare the following to be a full, clear, and exact description of the 1nvention, such as will enable others skllled in the art to which it appertains to make and use the same.

This invention relates to an improved folding cot and has special reference to a cot used for camping purposes. One object of the invention is to provide a cot havin an improved type of metal frame forme of angle iron and so constructed that the side rails may be disconnected from the supporting legs and the supporting legs released rom an extending or operative position to a folded osition against the end bars, the side rails being formed in separable sections which may be rolled into the fabric or spring structure when the cot is not in use.

Another ob'ect of the invention is to provide improve means for releasably connecting the sections of the side rails, the inner end portions of the side rails being positioned in overlapping relation and so connected that they will be securely but releasably held in engagement with each other.

Another object of the invention is to so construct this connection that the sections of the rails will be prevented from having transverse movement when connected.

Another object of the invention is to provide a cot which will be strong and durable, simple in construction, cheap to produce and easy to assemble or take apart.

This invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view of the improved cot.

Fig. 2 is a perspective view showing one corner portion of the improved cot.

Fig. 3 is a fragmentary perspective view showing one end portion of a side rail in engagement with a supporting leg, the supporting leg being shown partially in section.

Fig. 4 is a perspective view of the overlapping inner end portions of the sections forming a side bar.

ig. 5 is a view showing the inner end portions of the sections forming a side bar in elevation.

This cot is provided with a frame formed principally of angle iron and rovided at each end with a cross bar or on her 1 havmg supporting legs 2 pivotally connected therewith by means of rivets 3 which extend through registering openings formed in the.

depending flange of the end wardly extending flanges of the supporting legs. These inwardly extending flanges extend beyond the lower ends of the outer or sides flanges of the supporting legs and the extended end portions are bent to provide seats 4 which extend inwardly and prevent the su porting legls from having a tendency tobe orced into te ground. Bracin strips o are pivotally connected with the epending flange of the end bar 1 and have their free end portions cut to provide pockets so that the bracing strips may be brought into hooked engagement with the pins 6 carried by the supporting legs. It will thus be seen bar and in- -that when the cot is not in use the bracng strips may be released from the supporting legs and swung upwardly to extend longitudlnally of the end bars. The support- 1ng legs can then be swung inwardly to extend longitudinally of the end bars and the wire sprm fabric 7 may be rolled to form a neat bun le.

The side bars are indicated in general by the numeral8 and each is provided with end sections 9 and 10 which are formed of angle 1ron. The inner end portion of the section 9 extends in overlapping relation to the section 10 when the two sections are connected and this section 9 has its inner end provided with notches 11 and 12 into which will fit the pins 13 and 14 carried by the inner end portion of the section 10. A pin 15 is carried by the depending side flange of the section 10 and will fit into a notch 16 formed in the depending side flange of the section 9, a latching plate 17 being pivotally connected with the side flange of this section by means of a rivet 18 so that the latching plate ma be swung to position the pin 15 in the note 19 of this latchin plate and thus serve to prevent downward movement of the inner end portions of the two sections 9 and 10. A plate 20 is connected with the depending side flange at the outer end of each of these sections 9 and 10 and is provided with a hook 21 and a snub 22, the hook 21 being adapted to pass through an opening 23 formed in the cooperating supporting leg 2 and the snub 22 being ada ted to pass through an opening OrSlQt 24 ormed in the supportin supporting leg above the opening or slot 23. It should be noted that the hook 21 is cut from its under edge to provide a seat or setting up the cot it will be assembled in an upside-down position. The end sections of the side rails will .be put in place with the hooks and snubs fitting into the slots 23 and 24 and the inner end portions of the side bars will be brought :into overlapping relation with the pins 13 and 14 fitting into the notches 11 and 12. Pressure can then be applied to the inner ends of the sections 10 and by downward pressure, the pins 15 of the two sections 10 will be brought into the notches 16 of the two sections 9. The securing or latching plates 17 can then be swung to the operative position disclosed in Fig. 1 and the cot will be secured in the setup position. In order to prevent any dan-y ger of side play between the overlapped end portions of the two sections 9 and 10, each ,of the sections 9 has been provided with a guard plate 26 formed of angle iron and secured to the side bar section 9 and provided with adependingside flange 27 for engag-' ing the inner edge of the section 10 and thus preventing any transverse movement. After the cot has been assembled, it can be turned over so that it will rest upon the ground in the operative position as shown in Fig. 1. When it is no longer desired to use the cot,-

. the operation will be the reverse, the cot being placed upon the groupd with the supporting legs extending upwardly and the fasteners 17 being then released and the pressure applied to swing the sections of the side bars upwardly. This will spring the inner end portions of the side rail sections out of enga ement and by further upward movement, t e end rails can be entirely dis connected from .the supporting legs. The bracing strips 3 will be moved out of engagement w1th'the supporting legs and the supporting legs swung inwardly after which the side rail sections will be placed upon the s ring fabric and longitudinally of the end are at one end of the fabric. The fabric will be'rolled and after the roll has been formed, a suitable strap or other fastener may be passed around the roll to retain the same in the rolled condition. I

' It will thus be seen that a cot has been provided which simple in construc i n ermit interlocking engageand which is easy to setup or take apart and which will be further held in a set-up position and not liable to collapse when in use.
