9 Claims. (Cl. 135-4) The present invention relates generally to collapsible housing structures, such as are characterized by tents, canopies, and other collapsible and portable protective structures. I

Although it is contemplated. that thepresent invention as herein described has its principal utility as a collapsible and, portable protective covering for automobiles, in the form of a collapsible garage, his to be understood that the principles, of the present invention as exemplified in the specific embodiment to be described are likewise applicable to other uses. For example, by appropriate design of the structure within the, scope [of the present invention, it may be utilized as a beach canopy, a patio covering, atent, or a utility storage hut. Basically, the collapsible housing structure of the present invention is provided with a structural framework formed from a plurality of hinged parts which may be readily operated between a compact collapsed condition, and a fully ex panded open condition, or'intermediate stages of expansion, wherein it functions as a protective housing. In order that the device may function asa protective housing as intended, the aforementioned structural framework supports and carries a fabric cover, which may be made of any suitable material depending upon the purpose for which the device is intended to begused. The fabric cover may be formed from plasticsheet material, convas, a reticulate screen material, or other sheet material as desired, and by the term fabric herein it is intended to encompass all such materials andother analogous materials.

Collapsible protective structures of the general type above referred to are known in' the prior art. By the present invention, however, there are provided certain improvements over the prior art structures which render the present device more practical and useful, and more easily employed. Fof example, as will become more apparent from the following detailed description of a preferred embodiment of the present device, by the present invention: there is provided a novel anchoring means for devices of this general character; there is provided a novel counter-balancing system therefor, whereby the collapsing and expanding of the device may be accomplished with a minimum of effort and the device is aiforded astable state intermediate its fully expanded and collapsed states; there is provided a novel linkage between certain hinged parts of the aforementioned framework, whereby certain hinged parts are restrained in relation to others, in 'orderthat the collapsing and expanding of the device maybe accomplished with an orderly array of the hinged parts; and by the combination of the foregoing novel features there is provided a collapsible protective housing structure which may be quickly and efliciently manipulated from a collapsed to an expanded position, and vice versa, by one continuous movementof one hand of the operator..

Accordingly, his one object of the present invention to provide a collapsible protective housing structure whereinthe device may'be eifectively and readily 'anchored-in such a manner as to facilitate" the readyxexpanding and collapsing of the structure. a

"ice

a collapsible protective housing structure wherein certain hinged parts are restrained to an appropriate degree with regard to relative movement therebetween, so as to effect an orderly array of the parts during the expanding and collapsing of the structure.

A further object of the present invention is to provide a collapsible protective housing structure which may be readily expanded and collapsed, and wherein the several hinged parts are always retained in orderly array during the expanding and collapsing of the structure to facilitate these operations.

A still further object of the present invention is to provide a collapsible protective housing structure whichmay be readily expanded and collapsed, and which has a stable state intermediate its fully collapsed and fully expanded states. x

Other objects and advantages of the present invention will become apparent from a considerationof the following detailed description of a, preferred exemplary embodiment of the present invention and in conjunction with the accompanying drawings, in which like numerals refer to like or corresponding parts, and wherein:

Fig. 1 shows the collapsible housing structure in fully collapsed state;

Fig. 7 is a sectional view taken along line 7-7 of Fig. 2, and showing a means for securing the fabric cover to the struts of the frame; and

Fig. 8is a sectional view taken along line 8-45 of Fig; 2.

Referring to the drawings, the collapsible housing structure comprises the basic frame members 11 and 12 hinged at 20 on one side, and the corresponding members 11a and 12a on the opposite side. therefrom. Extending from and interconnecting the basic frame members are a plurality of

fabric supporting hoops

13, 14, 15, 16, 1'7, and 18, which carry and support the fabric material 19. The fabric 19 may be secured to the respective hoops by the formation of pockets, as provided by the application of strips 44 to the main portion of the fabric, as shown in Fig. 7.

Considering the foregoing basic components in greater detail, the

basic frame elements

11, 11a, 12 and 12a are shown as channel members into which the ends of ground hoops or

struts

13 and 18 are fitted and secured. As is readily apparent, frame members 11, 11a may be formed as a unitary piece with hoop 13, and similarly for

members

12, 12a and 18, so that in substance these two combinations of elements may be looked upon as the basic frame elements. Between the ends of frame members 11 and 11a, and at one end of the

frame members

12 and 12a, there are formed the plates 21 and 22 on members 11 and 12, and corresponding plates 21a and 22a on members 11a and 12a, for pivotally supporting the several aerial hoops or

struts

14, 15, 16, and 17, as will be more fully described hereinafter. As stated above, the adjacent ends of members 11 and 12 arehinged at 20, and their hinged ends are angularly upturned at 23 and 24, in order to enable effective counterbalancing action by spring 25 connected between plate 21 on member 11 and the tip 26 of theupturned end 24 of member'12. It can thus be seen that if

members

12, 12a and appurtenant hoops are swung about the pivot 20 between the collapsed position of the structure, as shown in Fig. l, and the expanded or extended position, as shown in Fig. 3, the spring 25 acts as a counterbalance, in that its most contracted position is obtained when the member 12 is substantially in a vertical position, or at substantially a right angle to element 11, as shown in Fig. 2. Thus, further movement of element 12 to either direction from the vertical is against the resistance of spring 25 to further expansion, and as the effective force of the falling member 12 becomes greater, the further expansion of spring 25 affords a greater resistance thereto. If desired, a turnbuckle or like structure 27 may be provided at one end of spring 25, so that its counterbalance force may be accurately adjusted. In addition to affording an effective counterbalance pivot by locating pivot 20 intermediate the ends of upturned portion 24, the

upturned ends

23 and 24 of members 11 and 12 provide for spacing between members 11 and 12 when the structure is in collapsed position, as shown in Fig. l, with members 11 and 12 lying in substantially parallel relationship. This spacing is designed to accommodate the

hoops

14, 15, 16, and 17 and the fabric 19 sandwiched therebetween, and thereby form a neat and compact package for the collapsed structure. It is understood that the structure and relationship of parts herein described with respect to members 11 and 12 find their counterparts in members 11a and 12a, and, if desired, a second counterbalance spring may be connected between elements 11a and 12a in the same manner as described for spring 25.

Considering the mounting of the aerial hoops or

struts

14, 15, 16, and 17 upon the plates 21, 21a and 22, 22a in greater detail,

hoops

14, 15 and 17 are mounted to their respective plates 21 and 22 by any conventional and simple pivot union, such as rivets or bolts, and similarly at their opposite ends to their respective plates 21a and 22a. A special mounting is provided, however, for hoop 16, as best shown in Fig. 4. One end of hoop 16 is pivotally mounted to plate 22 at 31 through the intermediate of bell crank member 32. The pivot union 31 per se may be any conventional means, such as a rivet or bolt. To the free end 33 of bell crank 32 is affixed a spring 34 which extends to and is afiixed at its other end to the end 26 of upturned portion 24 of member 12. Spring 34 is affixed to these two points under tension, and if desired, a turnbuckle or like device 35 may be interposed between one end of the spring and its anchor, as at 26, to adjust the tension of this spring. The immediate effect of tensioned spring 34 is to tend to pivot hoop 16 about 31 in the direction of hoop 18. If desired, a similar spring and bell crank combination may be provided at the opposite end of hoop 16 in conjunction with plate 22a.

To further explain the function of spring 34 and lever 32, its operation will be here described with particular reference to Fig. 4 in the process of collapsing the housing structure from a fully extended position as shown in Fig. 3, to a fully collapsed position as shown in Fig. 1. As the assembly carried by

basic frame members

12, 12a is pivoted about 20 toward collapsed position, the fabric between

hoops

15 and 16 tends to slacken as hoop 16 approaches toward hoop 15. However, by the action of spring 34 on lever 32, the slack is initially taken up by resultant rotation of hoop 16 and lever 32 about pivot 31 toward hoop 18. This action continues as members 12, 12:: are pivoted, until

members

12, 12a are in a substantially vertical position, as shown in Fig. 2. At that time, hoop 16 is in substantially parallel alignment with hoop 18 and

members

12, 12a, and it is to be noted that .hoop 16 has picked uphoop 17 in the process of pivoting 4 under the action of spring 34. Upon the further folding of the structure to bring

members

12, 12a past the vertical position to fully collapsed state, the tension remaining in spring 34 continues to hold hoop 16, and hoop 17 therewith, against hoop 18. On unfolding or extending the collapsed structure, the action of spring 34 and bell crank 32 is the same, functioning to hold

hoops

16 and 17 against hoop'18 until

members

12, 12a have passed the vertical position and until the fabric between

hoops

15 and 16 becomes taut and restrains hoop 16 against further movement with hoop 18 and

members

12, 12a. If it were not for the foregoing action of spring 34, there would exist the tendency of

hoops

16 and 17 to fall away from hoop 18 as

members

12, 12a passed the vertical position on collapsing the housing structure, and similarly on unfolding the collapsed structure. Such action would likely damage an automobile housed within the structure, and would result in such a disarray of hoops during the collapsing operation that it would become difficult to fully collapse or fold the structure. As is apparent from the foregoing description of the action of spring 34, it further functions in assisting spring 25 to counterbalance the weight of the half of the structure associated with

members

12 and 12a, between the vertical position of

members

12 and 12a and the fully extended position of the structure.

A further feature of the present invention resides in the provision of anchoring pad structures 40, 40a affixed to the two main frame members 11 and 11a, as by welding to the bottom of the frame members; and if desired additional structure such as

plates

41, 41a may be welded to the tops of members 11 and 11a and to the tops of pads 40, 40a. If desired, the pads 40, 40a may themselves be made of sufiicient weight to anchor the structure, but since this would add considerably to the weight of the structure, it is preferred not to employ such construction. Rather it is contemplated that the pads 40, 4001 be designed to receive an auxiliary weight thereupon for anchoring purposes. In the case of the present specific embodiment which is designed and primarily intended to house an automobile, as a collapsible and portable garage therefor, the pads 40, 40a are designed to receive a pair of wheels (front or rear) of the automobile, the weight of the automobile thereby functioning to anchor the structure. To this end, wheel pads 40, 40a are provided with front and rear wheel stops 42, 42a and 43, 43a to guide the proper positioning of the wheels upon the pads. If desired, the pads 40 and 40a may be made as a single cross piece, instead of the two piece construction shown.

Thus, in operation of the present structure, with the structure in collapsed position as shown in Fig. 1, an automobile may be driven to place its front wheels in position upon the wheel pads 40, 40a. With the structure thus anchored, one may grasp a handle 44, conveniently freely pivotally secured to hell crank 32, and by one continuous arcuate motion swing the structure into the fully extended position shown in Fig. 3. Due to the action of counterbalance spring 25, this may be done with a minimum of effort. Also, due to the effect of spring 34, the hoops are retained in orderly array and are restrained from falling upon and damaging the automobile during the unfolding operation. The collapsing or folding operation is similarly eflfected, with

springs

25 and 34 functioning for the same purposes.

Also, because of the particular arrangement of angularly turned ends 23, 23a and 24, 24a of

members

11, 11a and 12, 12a, it is apparent that the tension exerted by counterbalancing' spring or springs 25 is least when the structure is approximately one-half unfolded, or when

members

12, 12a are in a substantially vertical position as shown in Figs. 2 and 4. Consequently, the structure has a stable position when half-way unfolded with

members

12, 12a in substantially vertical position; and because of the action of spring or springs 34, the hoops in this position of the structure are in orderly array. In view of, this feature of the present invention, the structure is well suited for purposes other than a portable garage or the like, as earlier stated, and may advantageously serve for such purposes as a patio cover, a beach canopy tent, or the like. For canopy or tent use, legs may be provided for the structure, if desired, to afford greater height to the overall structure, as is readily apparent to those skilled in the art.

Having by the foregoing description described in detail one specific embodiment of the present invention, it is not intended to limit the scope of the present invention thereto, for many modifications thereof will be apparent to those skilled in the art. Accordingly, such modifications as are within the spirit and scope of the appended claims are contemplated by the present invention.
