TENT CONSTRUCTION.

if Application fil ed November 9, 1925. Seria1 No. 67,713.

T all whom it may concern:

Be it known that I, CnARLn-s B. Lnrrnnr,

a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Tent Constructions, of which the following is specification This invention relates to improvements in tent constructions and consists of the matters hereinafter described and more particularly pointed out in the appended claims.

One of the objects of the present invention is to provide an improved door arrangement for a tent, which includes two door members of flexible material, one of which is storm proof, and the other of which is insect proof, either of which may be manipulated to close the door opening while the other may be folded to one side and there secured in an out of the way position. v

A further object of the invention is to so support the top and bottom parts of the doors that they are substantially tautwhen in closed position and to provide a pocket '7 at one side of the door opening into which the free margins of the doors may be secured from either the inside or the outside of the tent.

Still another object of the invention is to provide a door arrangement for a. tent, wherein the use of snap fasteners are eliminated, which costs less to manufacture, is easier to operate and is more eflicient in use for its intended purpose.

These objects of the invention as well as others together with the many advantages thereof will more fully appear as I proceed with my specification.

In the drawings:

Fig. 1 is a perspective View of a tent construction embodying my invention Fig. 2 is afragmentary view in elevation on an enlarged scale of that wall of the tent embodying the door opening and associated door members.

3 is a detailvertical section on a furtheren'larged scale through that wall of the tent embodying the top part of the door openinga s taken on the line 3 3 of Fig. 2.

i t: l i iffi ff etjc ."Fig. 4t is a""fi"agmentary horizontal =s'ecm .f be, a 2 w w r 4 c w F-igzo 1s still anothe horizontal sectional;

The invention is herein illustrated and described as embodied in. a tent of the socalled umbrella type but this is to be taken by way of illustration only and not by way of limitation because as will be apparent the invention is also applicable to other types of tents where the, peculiar characteristics of the invention make it advantageous to do so.

' Referring now in detail to that embodiment of the invention illustrated in the accompanying drawings, 1 indicates as awhole a tent of the umbrella type having a front wall 2, side walls 3 3 and a rear wall 4, and associated triangularly shaped top wall or roof sections 2 -3 and 4*, respectively, all of which are made of a suitable tent fabric. The front, side and rear walls in this instance are inclined upwardly andinwardly and the associated top wallsect-ions, meet at 7-5 the apex of the tent and is there provided with a. grommet 5 to receive the usual pin 6 of the center pole. At the four corners of the tent, at the junction of the wall and roof sections, grommets are provided'to receive the hooks 8 associated with the arms on. the center pole.

The bottom corners of the tent may be secured to the ground in any s-uitablemannei' so that the wall and roof sections are sub stantially taut. In making up the front wall of thetent, I employ two front wall sections 9 and 10, the outer edges of which are cut to form the inclined corners and the inner margins of which are made parallel but spaced apart to provide a rectangular door opening 11 at the middle of said front wall. If desired a floor fabric may be embodied in the tent and if such be the case, the margins thereof are attached to the bottom margins of the side wall sections. Associated with the inner margin of the front wall section 10 and extending from the top to the bottoin on" the inside"thei"'eof,fis a strip of flexible material stitched at 1'2; to said margin along a line spaced from the" edge thereof to form a flapilS, which we gether with said wall "margin defines? pocket 14 along one side of the "door open ing, as best shown in Fip- 5. Associated with the infierniajrgin of t e btlicfi; an section and extendiii; from g bottonron the id tlifreof i's*anbthei" of flexible rnaterian tirchecr as at""15 "t margiii'aibiig mine s ac d he the edge thereof to form a flap 113, the purpose of which will later appear. At the top of the door opening, on the outside of the front wall sections is a transversely extending head strip 17 which overlaps at its ends upon and is secured to the top end portions of said front wall sections and is secured along its top edge to the underside of the topwall section 2 by means of a line of stitching and a reinforcing tape as best shown at 18 in Fig. 3. i p The bottom ends of the .tlaps 13 and 16 are connected together .by a. transversely extending strip 19 which forms a suitable threshold for the door opening and coacts with the headstrip to maintain the margins of said wall sections in their proper relations.

Associated with the door opening 11 are inner and outer doors 20 and 21 respectively, both of flexible material, the inner door being made of an open weave fabric such as bobinet for the purpose of providing ventilation to the exclusion of insects and termed an insect proo-f door, and the outer door being made of tent fabric and termed a storm door. 'llhe inner door 20 is stitched along one margin to the margin of the flap 16 and the outer door 21 is stitched to the margin of the front wall section 7 near its edge as best shown in Fig. 5. The top and bottom margins of the inner door have suitably spaced eyelets 22 and 23 therein and the top and bottom margins of the outer door are likewise provided with eyelets 24 -25 to receive flexible members in the form of cords for supportim said top and bottom margins of said doors when they are folded back against the associated margin of the Wall section and unfolded therefrom. to open and close said door opening. A looped cord or cable has one of its portions 27 passed through the eyelets at the top of the inner door from opposite sides of said door while its other portion 28 is passed through the eyelets at the top of the outer door from opposite sides thereof as shown in Fig. 4. The looped cord is so supported as to remove the strain of therdoors from the tent fabric adjacent the door opening as follows :--The ends of cord loops provided by the cord portions 27 and 28 extend through rings 29 and 39 respectively each fixed to one end of an associated tape 31 and 32. The tape 31 extends along the inner surface of the top end of the wall section 9 and has its other end secured to the tent fabric nearthe asse ciated eyelet 7 engaged with. one of the pole hooks 8. The other tape passes between the flap 13 and the margin. of the wall sec tion 10 near its top and is secured to the tent fabric near the associated eyelet -7 engaged with the other pole hook 8. Thus the looped cord which is drawn taut is secured to the tent fabric at points spaced the margins'of the wall sections defining the door opening so that said wall sections will not sag or be pulled out of shape. Said cord is so arranged that its ends are only tied together asshown in Fig l so that should it stretch, this stretch may be taken up and the cord again made taut.

A second looped cord is provided for the bottoms of said door members and said cord includes cord portions 33 and 34, the first passing through the grommets 23 at the bottom of the inner door from opposite sides and the second passing through the grommets at the bottom of the outer door from oppositesides as best shown in F ig. 6. The looped ends of said cord portions, pass through rings 35 and 36, respectively, the ring 35, being fixed to a tape 37 secured in between the flap l6 and the margin of the wall section 9 and the other ring being fixed to a tape 38 secured between the flap 13 of the margin of the wall section 10.

On the inner surface of the inner door, about midway between its top and bottom ends is located a tape 39 stitched to the door, with the stitching stopping short of the free margin of the door. The unsecured end of the tape 39 slides through one end of a snap hook 40 and the free end of the tape carries a ring 41. A cord 42 is fastened to said ring and the free end of this cord is adapted to be tied to a second ring 43 secured to that end of the tape 39 on the fixed margin of the door. A tape M is secured to the inner surface of the outer door in a manner as just above described and the free end of the tape slides through one end of a. snap hook 45, the extreme free end of thetape carrying a ring 46. One end of a cord 47 is fastened to said ring and its other end is adapted to be tied to a ring 18 on that end of the tape 4:4, fastened to the margin of the wall section 9. Both hooks 410 and may be snapped upon a ring 19 secured to one end of-a short tape section 50 located in the pocket 14. Should the material of the doors sag or stretch they may again be made taut by untying the cords 4'2 and 17 from the rings 43 and 18, taking upthe sag and again retying said cords to the rings 43 and 48, respectively. Should it be desired to use only the inner door so that the door opening is closed against the entrance of insects but at the same time to permit ventilation the outer door is pushed toward the wall sections 9, sliding upon the cord loop; portions 28 and 34 and at the same time folding up against the margin of the wall section to which it is attached, said door being secured in this folded position by inserting a tape 51 so cured to the outer surface of the wall section 9, tl'irough the ring 16. The inner door is then pulled over so that its free margin enters the pocket 14 and the hook 40 is snapped into the ring 49. In this manner even though the door is inclined from the vertical it is supported at not only its top and bottom but also at its middle, so that when used to close the door opening it is taut and smooth. With its free margin arranged in the pocket 14, noinsects can entertherethrough and the head strip and threshold strip effectively prevent the en trance of insects from the top or bottom of the door.

lVhen the inner door is not needed itmay be folded back against the margin of the wall section 9 and secured thereto inan out of the way position. In stormy weather, the outer door may be usedto close the door opening in the manner described in connection with the inner door. lVith the outer door in its closed position it prevents the entrance of rain, snow or wind about the margins of the door as is apparent. Should it be so desired, both doors may be opened or closed from either the inside or outside of the tent.

In connection with the doors, I provide an improved structure, which 'may be used either as an awning or another closure for the door opening as when the tent is left unoccupied. This structure includes a flap made integral with the top wall portion 2 and of a width equal the base of the same and of a depth equalling that of the front wall formed bythe wall sections 9 and '10.

Vfhen used for an awning, it is extended horizontally and its free edge is supported by poles 54:, only one ofwhich is shown in Fig. l. \Vhen used to cover the door opening, it is brought into position against the front wall to cover the door opening and is secured thereto in any suitable manner. Said flap being wider than the door opening, it securely seals the same at the sides and being integral with the top wall section presents no seam or ridge at the top of the door opening whichwill act to collect water in case of rain or snow.

My improved construction provides a door arrangement for a tent, the advantages of which are apparent from the foregoing description. lVhile in describing my invention I have referred to many details of construction as Well as form, arrangement and location of parts, I do not wish to be limited thereto except as may be pointed out in the appended claims.
