FOLDING coax] Application and August 29, 1925. Serial No. 53,230.

1 This invention relates to improvements in folding cots and consists in the matters hereinafter described and more particularly pointed out in the appemiled claim.

' One er the objects of the present invention is to provide an improved means for locking the cot in its open position rea'dy for use so that the cot may be shifted or carried about when in said open position without danger of it folding up due to the lifting up on the side rails thereof.

A further object of the invention is to provide an improved fabric or top for the cot which prevents the passage of cold air therethrough and includes cushioning parts along the side rails to prevent the engagement of the limbs of the occupant upon said side rails. i f

The above (mentioned objects of the invention, together with others as Well as the many advantages thereof will more fully appear asI proceed with my specification.

1n the drawings Fig. l is a perspective view of a folding cot embodying my invention as it appears when in its open or unfolded position ready for use.

Fig. 2 is a v'iewxin front elevation on an enlarged scale of the pivotal connection bet'weerrthe leg members of one of a pair of leg forming apart of'my improved cot construction. l

Fig.3 is a horizontal. detail sectional view as taken on the line 33 of Fig. 2.

Fig. 4 is a detail sectional view through one of the side rails and associated margin of the fabric top of the cot on a further enlarged scale, the plane of the section being indicated by theline 4P of Fig. 1.

Fig. 5 is a perspective view on an enlarged scale of one of the bracket plates embodied in the plvotal connection between the leg members of one of a pair of legs embodied n the cot. 1

Fig. 6 is a perspective view of a latch member on an enlarged scale secured to one' of the leg members and adapted to engage theother leg members in amanner locking them in their open or extended position.

Referring now indetailto thatembo'dinientfof theinvention illustrated in the accompanying drawings z-My improved cot comprises folding side rails 11, and foldable X shaped end and intermediate legs 22 and 3 respectively, all made of a standard light weight tubular stock, and a fabric top 4 operatively connected to and enclosing said side rails 1--1.

The side bars or rails each comprises two sections 1 -1 which when the cot is in its open extended position ineetor substantially abut at their inner ends in the plane of the intermediate legs 3 and engage the top ends I of said legs which provi e stops for said meeting ends of said side bar sections. Said abuttingendsof each pair of side rail sectionsareconnected to said intermediate leg 3 by means of T shaped brackets 5 as best shown in Fig. 1.

The fabric top 4 is preferably made of top and bottom fabric membersfi and 7 respectively (see Fig. 4) and a suitable padding maybe interposed between said members and quilted or stitched thereto to exclude the cold air which comes through a single thickness top and chills the occupant. Thelateral margin 7 of the bottom fabric member, which is wider than the top fabric member 6, is folded under and stitched to the main body of the fabric as at 8 to pro-- vide a longitudinal pocket 9 at each side of the fabric to receive the associated side rails 11.' The lateral edges of the top fabric 6 are stitched as at 10 to the mar inal parts of the bottom fabric 7 to provitfie a pocket above each rail to receive a cushioning material or padding 11. As the side rails are made of a stock of substantially small. di-

ameter in order to save material and cut down weight, they were heretofore quite annoying to the occupant when shifting positions upon the cot. However, with my improved top fabric, said rails are padded along the top as before described so that the annoyance of bumping the hard rails when occupying the cot is eliminated. Both fabrics are cut away in the vicinity of the brackets 5 to permit the folding of the sections formed a notch 14 the purpose of which will appear later. The mid portion of the leg 13 extends between the mid portions of the associated connecting plates 14 and a rivet 16 passing through said leg portion and plate portions provides the pivotal connection between the leg members 19. and 13. The top ends of said leg1 member are attached to brackets 17 w ich in turn are connected to the ends of the side rails 1-1 in a manner permittin a folding movement between said side rais and leg members.

- Such a connection between the leg members is strong and rigid and the leg parts are so arranged that when the legs are in their open crossed position, the adjacent end of the leg members 12*l2 abut or engage with oppositely disposed points on the mid portion of the leg member 13, which points are spaced apart as shown in Fig. 2. Heretofore when the cot was in its open position and an upward lift was imposed on the ends of the side rails as when carrying the cot about, the leg members would fold together about the axis 16, thus permitting the cot to fold longitudinally against the desires of the persons thus moving the cot.

To overcome this objectionable feature I have, provided a simple and efiicient means which is carried by one leg member and adapted to be moved into engagement with the other tolock said leg members in their open crossed position. As herein shown, said device is in the nature of a bifurcated latch member 17 (see Fig. 6) including spaced side arms 17'l7 which are connected together at one end by a bridge 17*. The other end of said arms embrace opposite side portions of the leg member 13 andare pivotally connected thereto by a rivet 18. When the leg members 12 and 13 are in their open crossed position as shown in full linesin Fig. 2, the latch member 17 may' be swung about the rivet 18 to bring the bridge 17 into engagement with the notches 14' of the plates l414 providing the pivotal connection between the leg members 12 and 13. The said latch is of such length that the leg section 12. slightly sprun outwardly to permit the edge of the bridge to clear that portion of the plate end above the notches 14' so that when said bridge enters said notches it cannot fall out even if the opened cot be reversed in position, top for bottom. The latch not only holds the legs in' their open position but keeps the fabric top taut. In case said fabric top stretches laterally through use, I provide a second notch 14 as shown in Fig. with which the bridge 17 of the latch may be engaged to take up said stretch. To fold said-legs together, the leg section is a ain s ruiw outwardl to ermit the b P D release of the bridge plate when the latch is swung about the pivot 18 toward the leg member 13, after-which the legs ma be relatively folded into the position s own in dotted lines in F i My improved simple in construction locks the legs in open crossed position so that the cot is rigidly held in the position ready for use and will not fold longitudinally when i'cked u by the side rails to be carried or s ifted about.

The improved fabric top revents the cold air or chill from passing t rough from below and also prevents the occupant from bumping the head, arms orlegs upon the hard side rails.

While in describing my invention, I have referred to certain details of construction as well as form and arrangement of the parts thereof I do not wish 'to be limited thereto except as may be pointed out in the appended claim.

I claim as my invention:

A folding cot embodying therein, side rails and crossed leg members operatively connected thereto, one of said members including leg sections, means including 5 ced plates connecting the adg'iwent ends 0 said leg sections together and between which the other leg member is engaged, means providing a pivotal connection between said other leg member and said spaced plates, which plates each have a notch therein, and a lntch plate including spacodside arms and a connecting bridge member at one end, the other ends of said side arms embracing a part of said other leg memberand pivoted thereto for a swinging movement to bring said bridge member into engagement with said notches in said spaced platesto hold said cross leg members in their imfolded open position.

In testimony whereof, I have helveunto set my hand, this 25th day of August, L924.
