modious shelter.

This invention relates to a folding camp tent, and in United States Patent particular to a tent which can be partially supported by an automobile when set up, and stowed in a carrier atop the automobile when struck, and is a continuation-in-part of my icopending patent application Serial Number 423,793, filed April 16, 1954, and entitled Folding Camp 'Tent, now abandoned.

In the event of forced evacuation of metropolitan areas, the provision of housing for the displaced population will become a serious problem. There are insuflicient build- :ings in dispersal areas to house even a small fraction of the people who will be sent to such areas. City dwellers :are generally unfamiliar with the more complex conventional camping tents, and in addition, such tents are bulky :and hard to store in the .small storage space available in a family car. The inability of these people to provide for their own shelter will place an unbearable load upon .the authorities in the time of an emergency.

It is therefore an object of this inventionto provide a folding camp tent which can be stowed in a carrier of relatively small compass compared to ordinary tent stowage 2,793,646 Patented May 28, 1957 ice the framework, and then, after fixing the covering to the framework, the reel can be tightened to give structural integrity to the tent.

. The above and other features of this invention will be fully understood from the following detailed description and the accompanying drawings, in which:

Fig. 1 is an isometric view showing a tent according to the invention erected alongside an automobile;

Fig. 2 is a plan view of the tent of Fig. 1;

Fig. 3 is an elevation taken at line 3-3 of Fig. 2;

Fig. 4 is an end view of the carrier of Fig. 1 particularly showing a means for turning the reel;

Fig. 5 is a detailed view of a post for use in the tent of Fig. 1; i

Fig. 6 is an isometric detailed view of a stifiening means between two adjacent structural segments; and

Fig. 7 is a fragmentary exploded view in perspective of another form of tent according to the invention adaptable to be set up separately of an automobile.

The tent of this invention is designed to be erected adjacent to an automobile 10 and is conveniently afiixed to the roof thereof by means of a carrier 11 which preferably comprises a pair of T-section

transverse members

12 and 13 which can be attached to the roof of the automobile by means of suction cups 14. These suction cups are best disposed at both ends of said transverse members. The transverse members are spaced from each "other by means of a cross-bar 15 and thereby form a base for the rest of the carrier (see Fig. 3).

This carrier conveniently has two

side plates

16, 17 having flanges which are affixed to flanges of the

transverse members

12 and 13. A metal floor for a storage compartment can be laid atop the flanges of transverse requirements, and which can be set up to provide a com- A related object is to provide the tent structure and stowage means in a simple mechanical form whereby even a person largely lacking in mechanical skill and camping experience will be able to set up or store the tent in a minimum time. this tent may be either set up or struck in as little as three minutes.

An optional object is to provide such a tent which can be detached from the automobile, thus providing shelter, but still permitting the separate use of the automobile.

The invention is carried out by providing a carrier at the side of the top of a car which accommodatesa reel upon which aflexible covering for the tent structure can be wound. A feature residesin segmented tent frame members which are pivotally mounted to this carrier so a as to be integral therewith, and these frame members may be swung out to provide a structure. If desired, additional stiffening members may be furnished. The segments of these members are joined by pivots so that the carrier need have a long dimension less than any edge dimension of the erected tent, thereby reducing stowage requirements. The length of the carrier thus ceases to be defined by the length of the longest edge of the tent, and the longest edge of the tent ceases to be limited by the length of the carrier. With this invention a tent can be stored in a carrier adapted to fit on a passenger car which formerly could only be fitted in a carrier of such a length that a stationwagon or other long-bodied vehicle was needed to'transport it. When the'framework is set up, then the flexible covering can beunreeled to-cover In fact, it has been found that rest of the car top.

members

12 and 13. The side plates have aligned

hearing holes

18, 19 for accommodating the shaft 20 of a reel assembly. Above the shaft an L-shaped hinge member 21 provides a lower hinge block for a hinge bolt 22 which passes vertically therethrough. At the same point of attachment to the side members 16 there is provided an L-shaped rest 23a for the purpose later to be described. Spaced from the hinge member 21 is another hinge member 23 in which there is provided a hinge hole for the same hinge pin 22 to pass through. This upper hinge support is also attached to side member 16. At the top of the carrier there is a cross-bar 24 which extends between the

side members

16 and 17 and is afiixed to a flange on each of these side members. It Will be observed that

side members

16 and 17 are disposed at the sideof the car leaving a floored storage area across the Below the cross-bar 24, on side member 17, there is disposed an L-shaped rest 25. Below that rest and on the opposite side of side member 17, is: a pair of spaced the side member 17 and has a projecting tooth which can drop into a space between adjacent teeth on the gear 28. At the extreme end of the shaft there is a crank comprising an L-shaped bar with one arm 31 passing transversely through the end of the shaft. This arm has an upset end 32 to hold it in the shaft. The handle 33 .of the crank may therefore be rotated about this arm so segments may be more or less than live, depending on the size and complexity of the tent to be erected, the

- number being shown in this example repre'sentinga preferred embodiment of the invention. Segment 34 is directly pivoted to the hinge pin 22, one end of segment 35 is pivoted to the free end of segment 34 by pivot 37 and 'one end of segment 36 is pivoted to the free end of segment 35 by pivot 38. A pivot 39 is provided at the free end of segment 36 for joining that'segm'ent to a leg 40which has two segments 41, 4'2 with a 'pivot 43 between them. It will be noted that 34, 35-and 36 make up 'a roof edge.

Pivots

37, 38, 39 and 43 are generally parallelto'each other, that is, they are substantially horizontal. They are therefore perpendicular to pivot 22. A spike 44 is provided'a'tthe foot of legdtl. A notch 39ais provided in segment '36 to receive a pin 3% on segment 41.

At the other hinge pin 28, there is provided another segment tent frame member 45a, comprising a segment 45 pivotedto vertical hinge pin or pivot 28, a segment 46 with a vertical pivot 47 joining it to the free end of segment 45, a segment 48 pivoted at 49 to the free end of segment 46, and a segment 50 pivoted at 51 to the free end of segment 48. A substantially horizontal pivot 52 joins segment 51 to a leg 53 which comprises three segments 54, 55, 56, a pivot 57 joining segments 54 and '55 and a pivot58 joining segments 55 and 56. A spike 59 may beprovided at the bottom of leg 53. A

. slot 46a is formed at the end of segment 50 to accommodate a post 46b on segment 54.

It will be observed that

segments

45, 46 and 48 make up a roof-edge.

Hinge 28 and pivot 4'7 are vertical and parallel, while pivots 49, '1, 52, 57 and 58 are substantially horizontal, parallel to each other and perpendicular to hinge 28 and pivot 47. V

The

segments

34, 35, 36, 41 and 42 are progressively.

shorter in that order, segment 34 being the longest and also being shorter than the distance between side members '16 and 17.

Segments

45, 46, 48, 50, 54, 55 and 56 are relatively shorter than each other in'that order,

segment 45 being the longest and also being shorter than the distance between

side members

16 and 17. Referring to the largest length, largest width, and the height of the tent as its edge dimensions, none of the segments, nor the width of the reel, is as large as any edge dimen- SlOXl.

. as 39b therethrough in order that they may be fixed at an end of

segments

36 and 50 respectively. This strengthening member 68 comprises a roof-edge. Another strengthening member 65 comprises three segments 66,

' 67 and 68 which are joined by

pivots

69, 70. The free end of segment 68 has a hole 71, and the free end of segment '66 has a hole '72, for joinder to posts 'on member 60 and segment 45 respectively. These pivots are preferably horizontal when the tent is erected. All of these segments are preferably shorter than the reel so that they can be stowed in the carrier.

A leg 73 comprising two segments 74, 75 (see Fig. 1) joined by a pivot 76 is provided with a post at its upper end for joinder with segment 45. This leg has a spike 77 on the bottom end thereof.

A tent with a floor area approximately 7 /2 x 4 ft. may be conveniently constructed by providing segments of the following dimensions:

It will be later observed thatall of these members may be conveniently folded into the carrier which will have a distance between side members of only 48% inches. The complete unit, includingall structure, the carrier and a flexible canvas covering weighs less than eighty pounds. Aluminum is the preferred substance for this tent, because ofits low specific gravity.

The details of a preferred pivot suchas pivots 37, 38, 49 and 51 between adjacent segments will be :seen by particular reference to Figs. 5 and 6. A slot 78 is formed in one flange of the L'-shaped segments, so that it slants away from the other flange, while a stud 79 is fixed to a flange of the adjacent segment .so it pro- .jects through the slot. Anut or some upset means 80 -is provided on the end of the stud to 'h'old' it in the slot. The end of the innermost flange is conveniently rounded otf at 81 to simplify the pivoting action. When the segments are generally parallel and shoved together, there can be no further rotation. When pulled apart, the segments can be rotated relative to each other.

As will be appreciated by reference to Fig. 6, a further means for providing rigidity .of structure and freedom from side sway comprises a finger 82 on the end of one of the segments, and a slot 83 in the other into which this finger may project when the segments are extended so as to be substantially parallel to each. other. This provides a certain amount of rigidity in respect to sway-motion of the tent structure. This-finger will befound on the upper side of the tent frame members, and is shown with 55.-

particular reference to the

joint betweeniframe members

46 and 48. This stiffening'means may be provided at all joints.

-A fabric covering for the structure is shown erected in Fig. l which comprises a-pentagonlal roof .sheet 84 and substantially

rectangular side sheets

85, 86, 87 and 88. Side sheet 88 is disposed so as to form :a wall drop 'ping over segment 45 while

si desheets

85, 87 and 86 drop from

segmented frame members

34a and 45a and from member 60, respectively. Zipper means are provided at'joints 89, 90 and-91 soth at pairs of side members I comprising -85, 86; 86, 87; and 87, 88 respectively may have the'shape'of separate flaps which can be joined after the fnamework is set up. Doors-and windows may be provided as'suitable for the user in the various-side sheets or even in lthe top.

It will be appreciated that for storage purposes, the side-sheet 88 may first be thrown atop the roof sheet 84. After that, the sidesheet 87 and whatever'other sheets extendon ea'ch'side of the midpoint of sheet 84 may be :f'oldedby carrying the bottom end "of sheet 87 over until it coincides with the bottom end of sheet 85. Then the bottom end of sheets 85 and 87 may be folded back on the top so as to create a folded fabric pile no wider than the reel 20.

In Fig. 7 there is shown a modification of the tent of Fig. 1 which permits the tent to be set up and then detached from the automobile so that the automobile may be driven away after the tent is erected. The same carrier is used, and the components common to the embodiment of Fig. I bear the same reference numerals. The same fabric covering is utilized, and, when the tent is not detached from the car, its erected configuration has the same outer contour. For clarity of exposition, only the frame structure is shown in Fig. 7, it being understood that the fabric covering shown in Fig. 1 can conveniently be utilized. For this detachable tent, it may be desired to pro vide an additional fabric sheet as wide as the reel and as long as the tent is tall to cover the gap which formerly was filled by the automobile.

Hooks 100 are provided on the reel 20 by means of which the fabric covering may be detachably fixed to the reel.

In order to make the tent frame structure conveniently detachable, headed drop pins 101, 102 are providedin place of the threaded hinge pins 22, 28 shown in Fig. 3.

The principal structural differences between this detachable tent and the non-detachable tent resides in the substitution of a jointed, two-piece member 103 in place of segment 34, which is attached to segment 35 by pivot 37, and of another jointed two-piece segment 104 in place of segment 66, which is attached to segment 67 by pivot 69. The

members

103, 104 and segment 45 are shown in solid line in the position they have when the tent is erected and fastened to the car, and in dashed line in the position they have when the tent is erected and separated from the car. t

The overall extended length of

members

103 and 104 is the same as that of

segments

34 and 66, respectively. Member 103 is divided into two

segment

105, 106, which are joined by a vertical pivot 107, and member 104 is divided into two segments 108, 109 which are joined by a horizontal pivot 110.

A leg 111 is provided which has a pin 112, long enough to project above the frame structure when inserted in a hole in the top of segment 106. This leg 111 is the same in all details as leg 73.

A patch segment 113 is provided, along with two sets of

fasteners

114, 115 for joining together

segments

105 and 45. This patch segment preferably is also L shaped in cross-section so as to make a rigid patch with

segments

105 and 45. The term structural frame, or frame as used herein means the member comprised of a plurality of segments which supports the flexible covering at an edge, the edge being defined as the intersection of two tent surfaces, such as the roof and a side, or two sides.

The technique of setting up and of striking the tent of Fig. 1 will be evident from the drawings, and particularly from Fig. 2, wherein there is shown in solid line the erected tent structure, and in phantom line there is shown some of the technique of folding and unfolding the segments.

When the tent is to be set up the automobile is parked in appropriate position, and the segmented tent frame member 34a which is attached to pivot member 22 is swung outwards and

segments

34, 35, 36 are unfolded to make a straight horizontally extending tent frame member, and

segments

41 and 42 drop downward to form a leg 40, the spike 44 of which may be pushed into the ground.

When the pivoting action is completed, the adjacent segments are pushed against each other so that further pivoting is prevented by their abutment. The movement at pivot 39 is restricted by the posts fitting into the slot 46a. The fingers 82 drop into the slots 83 to reduce side-sway between the tent frame members.

Thesegmented tentframe member a attached to pivot 27 is swung out so that segment 45 makes an acute angle with the forward direction of the automobile, and

segments

46, 48 and 50 are extended in a line generally perpendicular to said forward direction of the automobile. Leg 53 drops, and its segments 54, 55, 56 form a straight vertical leg with an end spike 59 which may be shoved into the ground. The same locking and sway preventing means are provided for this frame member as for the other. Then the cross member 60 is placed between pivot points 39 and 52 of the two horizontally extending structures.

The

posts

39b and 46b hold the legs at right angles to the adjacent segments, and fingers 82 fit into slots 83 for stiffness. The leg 73 is next placed. under segment 45.

The canvas is unreeled until it mostly rests on the ground between the two segmented tent frame members. The side sheets are unfolded and. lifted over the side members. Their weight draping over the frame pulls the top sheet 84 taut. be placed between the segment 45 and segment 62.

The covering fabric is provided at the various corners with grommets through which the spikes at the bottom of the legs may or may not be inserted. Also, if a fabric floor is to be used, to keep out the humidity of the ground, it will be attached to the legs at this time. The Zippers 89, 90 and 91 are closed so as to join the various sidesheets.

To tighten the covering fabric and give the tent complete structural integrity, the crank handle 33 is swung out so as to be substantially perpendicular to the side member 17; the dog 29 is lifted, and the crank is turned until the sheets are drawn tightly against the supporting structure. Tightening the fabric puts all of the supporting members of the tent in compression, and also provides side support against buckling. Thus, the term structural integrity refers to a strengthening which substantially resists collapse of the tent structure. Then the dog is dropped into a space between adjacent teeth on the gear 38. The handle 33 is swung out of the way, and the tent is assembled and ready for use. It will be appreciated that much structural integrity will be given to the tent simply by tightening the canvas by turning the reel, even if the spikes at the bottom of the legs are not inserted in grommets in the side sheets.

When the tent is to be stored the reverse procedure is followed and it will be appreciated that the entire structure including all of the folding members may be fitted conveniently within the carrier.

The flexible covering is unfastened from the frame and the Zippers are opened. The covering is then folded to a size no wider than the reel leaving cross-member in place, and the covering is wound thereon. Then cross member 65 and strengthening member 60 are removed, folded, and stored, and then the legs and the segmented tent frame members are folded up. Most of the structure is pivotally jointed so that when folded, there are two pieces which can be pivoted into the carrier to rest on the

supports

23a and 25. There will be three separate assemblies, that is, two cross members and one leg which must be separately stowed in this embodiment. These separate members are also preferably of shorter length than the carrier so that they may fit therein. When the se ments are folded, they fit one within the other, and form a bundle no longer than the longest of the segments.

The erection and striking of the tent of Fig. 7 is the same as has just been described in connection with the tent of Fig. 1. In fact, when

segments

103 and 104 are fully extended and segment 45 is attached to the carrier, the resulting tent configuration is exactly the same.

When the erected tent is to be freed from the automobile, leg 111 is placed under segment 106. Then guy ropes are fastened in pairs to all four corners to elimi-i Now the member 65 may 8 7 hate side-sway. Pins Mind 102 are next pulled out of the hinge members, and segment 105 is swung horizontally underneath segment 104 to point at pivot 107. Strengthening member 65 then rests atop segment 45, and segment 108 is swung vertically so as to dangle freely.

Then patch member 113 is bolted to

segments

45 and 105, creating a rigid roof frame member or roof-edge. The tent fabric may then be released from hooks 100, and dropped to cover the area under this member, and a four-sided tent results which is free of the automobile. The automobile may now be driven away.

When the tent is to be struck, the member 103 and segment 45 are again connected to the carrier. The fabric covering is reconnected to the reel, and the storage of the tent is carried out as described.

By this invention there is provided a tent which can be conveniently stored within a carrier of small compass and which may be expanded to dimensions significantly larger than any of the dimensions of the carrier. Such a tent will be found very useful for persons interested in camping and camping activities and will also find a convenient and widespread use as an evacuation housing means, since in its small storage requirements there is provided a commodio-us living facility.

This car camp is also very practical for use as housing while fishing in the mountains or at the beach as well as for camping in the desert or while as on any trip when in locations where suitable hotels and motels cannot be found (such as certain areas of Mexico). It could also be used for saving hotel and motel expenses while traveling since it requires only 3 minutes to set up.

It will also be observed that this tent and its carrier require storage space only at one side of the automobile, and a substantially shorter length than the length of the automobile, and thereby leaves a large space toward the center of the car, within whichluggage and dunnage such as tables and chairs, stoves and sleeping bags may be stored as desired. This leaves the trunk and the interior of the car free for use of the passengers.

The embodiment of Fig. 7 furnishes further advantage that the tent may be released from the automobile, so that it is unnecessary to strike the tent whenever it is desired to drive the car. By the provision of the extra jointing in the tent frame members all the advantages of a tent which remains fixed to the car can be retained, and the further advantages of a detachable tent are obtained.

This invention is not to be limited by the embodiments shown in the drawings or described in the description, which are given by way of example and not of limitation, but only in accordance with the scope of the appended claim.

I claim:
