NE TTING SUPPORT FOR COTS Filed July 2, 1937 INVENTOR 57 (z/us War/ken 52 A RNEY v Patented Apr. 18, 1939 UNITED STATES PATENT OFFICE 6 Claims.
This invention relates to a net and net support for folding cots, beds and the like, and has for its principal object to provide a construction of this character that is readily applied to an exist- 5 ing type of folding cot, and which may be removed and folded with the cot for transportation and storage purposes.
Other important objects of the invention are to provide a net support constructed to retain 10 the net in taut condition; to provide a support which is relatively inexpensive to manufacture; to provide a support that is readily adjusted for attachment to the cross bar of a cot; and to provide a support shaped so that the side walls of v 15 the tent are kept in contact with the sides of the cot.
It is also an important object of the invention to provide a net with attached pockets to engage over the supports, thereby relieving wear and 20 tear on the netting.
In accomplishing these and other objects of the invention, as hereinafter pointed out, I have provided improved details of structure, the preferred form of which is illustrated in the accom- 5 panying drawing, wherein:
Fig. 1 is a perspective View of a folding cot equipped with a net and net support, embodying the features of the present invention, part of the netting being broken away to better illustrate the pocket for retaining the netting on the cross bar of the support.
Fig.-2 is a fragmentary perspective view of a portion of the net as viewed from the interior thereof, particularly illustrating the pocket.
35 Fig. 3 is an enlarged perspective view of one of the supports.
Fig. 4 is a detailed perspective View of one corner of the cot illustrating application of the support to the cross bar of the cot.
40 Referring more in detail to the drawing:
I designates an ordinary folding cot, including parallel side bars 3 and 4, each comprising end sections 5 and 6 hinged together at the center of the cot, as indicated at l. g
45 side bars is a canvas covering 8 having hemmed ends 9 and I to form pockets for passing cross bars I l and I2 at the head and foot ends of the cot. The cot is supported adjacent its ends and center on the crossed legs l3 and I4 pivoted to- 50 gether so that they may be folded parallel with the side bars when the cot is folded for storage or transportation purposes. The side bars are provided with dowels I5, projecting from the ends thereof to engage in openings [6 of the cross bars 55 when the cot is created. The ends of the cross Secured to the bars project beyond the side bars as shown at I'l-l 8, Fig. 1. The cot thus described is of standard construction and specifically forms no part of the invention, but is illustrated to give a better understanding of the present invention as now to be described.
l9 designates a net including a top 20 having depending side walls 21-22 and end walls 23-24 to form a rectangular enclosure for protecting the occupant of the cot. The top 20 of the netting is of smaller dimensions than the length and width of the cot so that the side and end walls are adapted to hang smoothly in close contact with the side and end bars as shown in Fig. 1.
Secured at the juncture of the end walls with the top are pockets 25-26 extending across the width of the top. The pockets are formed by folding a strip of fabric material along the median line thereof to form side portions 26-21, which are stitched together at the ends to form downwardly opening recesses to receive the supporting members later described. The folded portions of the strips are secured to the netting by lines of stitching or the like as indicated at 29, Fig. 2, so that the pockets form a permanent part of the net. One of the side Walls of the net, for example 2|, is formed in two sections 30-31, having overlapping ends 32-33 to provide an opening 34.
35 and 36 designate supports for the net, each 30 of which includes a cross bar 38 corresponding in length to the pockets. The cross bars 38 have round ends 39-40 and pivoted thereto by pins 4l-42 are similarly rounded ends 43-44 of upright bars 45-46, the bar 45 being attached to 35 one side of the cross bar, and the bar 46. to the other, so that when the bars are moved into folded position one of the bars extends along one side of the cross bar, and the other along the opposite side. The upright bars are of a length 4 to properly space the top of the net from the cover of the cot, and the lower ends thereof have loop-like clamps 41-48; the clamps being formed by bending the bars laterally as at 49, then downwardly as at and again laterally as at 5!, 45 thence upwardly as at 52 to the plane of the lateral bar 49 where the bar is again bent as at 53, and thence upwardly at 54 so that the terminal ends 55 thereof extend substantially parallel with the upper portion of the bars. 50
The loop-like openings 56 formed by the bends are of slightly smaller dimensions than the crosssectional dimensions of the cross bars of the cot, to leave a space 5! between the terminal ends 55 and the upper portions of the bars. Slidable 55 h p the cross bars of the cot.
' shown in Fig. 4. The bends are preferably formed 7 so that the upper portion and terminal end 55 of the bars extend upwardly from the median line of the clamps. V
In order to stretch the net the bars are preferably bent outwardly, as indicated at 59-60, so that the cross bars 38 of the respective supports are normally spaced a greater distance than the length of the net. 7
In applying the supports constructed and assembled as described, the loops 58 are-moved upwardly out of engagement at the terminal ends 55. There is then sufiicient tension in the metal so that the loop portions expand to permit sliding thereof over the projecting ends l'l-l8 of the cross bars of the cot. The terminal ends 55-are then pressed against the upper portion of the bars so that the loops may be slid thereover to draw the clamps into clamping engagement with The net is then extended over the supports in such a manner that the cross bars 38 engage in' the pockets and When the net is applied to the supports the side and end walls hang in close contact with the bars of the cot so as to close the spaces therebetween.
' The netting is readily removed by withdrawing the pockets from the supports after which loops 58 are again released so that the supports may be withdrawn from the ends of the cross bars.
The upright bars -45 are then free to be moved into juxtaposition with the cross bar 38 to complete folding of the supports. The folded ily applied to a conventional cot and whichare.
rigidly retained in functional position when applied.
What I claim and desire to secure by Letters Patent is: V
