COLLAPSIBLE SHELTER
ABSTRACT OF THE DISCLOSURE.
A folding shelter is taught, which comprises a shell supported over a plurality of hoop-like frame members, and secured to a pair of base members of substantially the same configuration as the frame members. The base members are secured to a pair of framing plates, which overlap each other slightly and are hingedly connected to each other by a pin connection which is placed near the top of the overlap area of each. The centre-most of the hoop-like framing members is hingedly secured to both of the framing plates at the same pin that they are hinged to each other; and the remaining frame members are independently hingedly secured at their ends to one of the framing plates. The attachment of each of the other hoop-like frame members to the framing plates is such that each succeeding frame member away from the centre-most member is connected to the respective framing plate at a point lower and further away from the pin connection of the plates to each other than the last succeeding frame member.

FIELD OF THE INVENTION:
_ _ This invention relates to folding shelters, particularly of the sort which may be otherwise termed to be a collapsible shelter of a portable type. The invention particularly relates to the structure of the shelter, specifically the hinging relationship of the framing members thereof.
BACKGROUND OF THE INVENTION:
There are many circumstances when it is desirable to have a folding shelter which may be portable and of low cost and light weight. Such circums-tances include, for example, shelters for workmen in inclement conditions, as well as camping shelters for one or two persons, and similar clrcumstances. Still other requirements for shelters may include ones which ma~
be placed over vehicles for protection against dust or inclemency, and so on.
n~S~N~N, in United States ~atent 33G~57~ da'.ed February 13, 19~8, teaches a portable and collapsible shelter which is of relatively small size and light weight, has a number of substantially radially directed members from a central pivot plate assembly, disposed at the centre of the top and bottom of the shelter, so that it is somewhat circular or hexagonal in plan. The ~pivot plate assembly comprises two plates pivoted to each other, with a plurality of frame legs pivoted to one or the other of the plates. However, the shelter is rather awkward to open, and relies upon a chain connected from frame member to f frame member to support the cover member and to regulate the spacing of the framework. Moreover, it is necessary to ensure that the pivot plates are properly aligned when in their unfolded f position, and lines are drawn on the pivot plates for those purposes. Thus, considerable effort and care must be taken when ;4 assembling or erecting the shelter.
Several other portable shelters have been ref~rred to in the past literature~ of some interest, including the following.
MACYj V.S. patent 3082780, dated March 26, 1963, which teaches a portable shelter having a number of foldable braces between bows which are pivoted at a single point on each side of the shelter.
MOLTCHAN, U.S. Patent 3121439, dated February 18, 1964, shows a plate on each side of the shelter, to which is pivoted a plurality of supporting members. However, it is only a single plate, and lacks the ability to collapse to a minimum possible thickness, and also to be easily erected from elther direction. Likewise, JOHNSON, U.S. Patent 3513861, dated May 26, 1970, teaches a structure having plate or footing members on each side of the structure to which a plurality of bows or framing members are pivotally mounted.
A somewhat different structure is taught in MATHEWS, U.S. Patent 4084599, dated April 18, 1978, which shows base members to which a plurality of struts are pivotally mounted only on one poxtion of the periphery of the ba~ member. Finally, BONFILIO, U.S.
Patent 4098281, issued July 4, 1978, teaches a collapsible shelter which has a central hub to which a plurality of ribs are mounted.
One feature in particular which has been desirable, but substantially unobtainable, is the capacity or capability of a folding shelter to be opened and closed -- erected and collapsed -- from either direction. Further, is has been desirable to provide such a structure which can be erected or collapsed with a minimum of operational steps and in a minimllm of time. These objects are achieved by the present invention.
It is also desirable to provide a structure which, particularly when intended for use as a camping shelter or the ? ) like, may be easily opened and closed to provide ent~ances ~la-~2~5~
and ventilation openings, etc. Such structure should, of course, be light in weight and, at the same time, weather proof at least so far as its ability to withstand wind and precipitation.
The principal features of this invention are, as noted, accomplished by the provision of a plurality of hoop-like frame members, of which at least two are base members which are adapted to rest against the supporting surface - the ground, a roor or oth~r construction surface, or the like -- with the shell of the folding shelter, which is made from fabric or other pliant material, being secured to the base members and supported by at least one further hoop-like frame member.
Usually, of course, there are a plurality of further hoop-like frame members, the centre-most of which is hingedly connected to a pair of framing plates which, themselves, are hingedly connected to each other by a pin connection. The framing plates are centrally located on each side of the shelter, and slightly overlap each other, with the pin connection between them being placed near the top of the overlapped area. Any other of the hoop-like frame members, except the centre-most, are hingedly connected at each of their ends to one of the framing plates, in such a manner that each succeeding hoop-like frame member away from the centre-most frame member is connected to the respective framing plate at a point thereon which is lower and further away from the pin connection between the framing plates than the connection point of the last succeeding hoop-like frame member.
So as to effect complete foldability of the shelter, without additional steps, the base members are firmly secured at their 29 ends to the framing plates, in a manner discussed hereafter.
Where it is desired that the folding shelter of the presen$
invention -- which would otherwise be ~ppropriately dimensioned -- may be folded sufficiently small as to fit into the trunk of an automobile, for example, the hoop-like frame members can be provided in such a manner that they are hinged at their centre point ~nd o~herwise conveniently -- e.g. upper outer corners, with support braces at the corners -- so that the frame member may be folded across their width.

DESCRIPTION OF THE PREFERRED EMBODIMENTS:
As noted, the principal purpose of this invention is to provide a folding shelter which may be ~sed either for camping purposes -- e.g., either to protect persons camping outdoors, or their belongings -- or for a shelter in which supplies or equipment may be stored for protectlon against the weather, or within which work may be carried out. This latter feature is particularly helpful in areas of extreme climate, where relatively light work such as roofing, certain kinds of telephone and electrical work, etc., might be carried out under a shelter according to this invention but not otherwise because of exposure to the elements and weather.
The folding shelter 10 of Figure 1 comprises two base members 12 and a plurality of hoop-like frame members 14. In the particular embodiment illustrated - a folding shelter having a base area approximately 2.5 meters x 3.5 meters -- the frame members 14 are designated as 14a, 14b, 14c, 14d and 14e; and the base members are designated 12a and 12b.
A shell 16 is supported by the frame members 14; and is secured around its edges -- at the bottom of the shelter -- to the base members 12 by snap fasteners 15 or other suitable fastening means.
The shell 16 may be made of fabric, for example canvas or 29 nylon, or other suitable pliant material such as rubberized -7~4 materials, fibre glass reinforced vinyl, etc.
Se~eral features of the shelter, particularly as it is shown in Figure 1 as it may be presented ~or purposes of camping and the like, are a ventillation opening 17 having net or screen covering 19 and a rollable cover 21 secured in its up position by tabs 23 and its down position by tabs 25. Also, there is a closable entrance flap 25 which may be opened and closed at zippers 27 and 29; and it will be noted that the entrance flap 25 is located so as to be positioned between the side portions of the hoop-like frame members 14b and 14c. Also, as noted in Figure 5, the shell 16 may be removably secured to the frame members 14 by means of a tab 29 and dome fastener 20.
Turning now to the features of the construction, particularly as they relate to the foldability of the folding shelter of this invention, it is noted that there are a pair of framing plates 18 which overlap each other, creating an overlapped area 20. The framing plates 18 are hinged together by a pin 22 which may have a cap 24 placed over one end. The positioning of the pin 22 is such that it is near the top of the overlapped area 20 It will also be noted that the centre-most hoop-like frame member 14c is hingedly secured to the framing plates 18 by the same pin 22.
The remaining hoop-like frame members 14a, 14b, 14d and 14e are also each hingedly secured at their ends to a respective one of the framing plates 18 by pins 24. Each attachment of a framing 14 to a framing plate 18 is such that each succeeding frame member away from the centre-most frame member 14c is 29 connected to the respective framing plate 18 at a point lower ~L~Z~754 and further away from the pin connection of the last succeeding frame member. For example, with reference to Figure 2, it is noted that the connection of frame member 14d to the right hand framing plate 18 (as viewed) is lower than the connect~on of the frame member 14c; and the connection of frame member 14e i5 lower than the connection of frame member 14d, and further away from the pin 22.
Reference is now made to Figure 3, showing the folding shelter 1~ in its folded condition. It will be seen that the framing plates 18 have changed their relative posi-tion to one another such that the framing plate designated 18a has moved from the position illustrated by the chain line in Figure 3 to the ~olded positi~n .illustrated, and as shown by the arrow 26. The manner in which the ~hell 16 has ~olded between the rame members 1~ is also noted.
As mentioned above, when the base members 12a and 12b -are secured to the respective framing plates 18a and 18b, then it is a very simple matter to erect or collapse the folding - shelter simply by manipulating.one or the other of the base members 12. For example, the left.hand ~ase member 12 (as seen in Figure 1) may be picked up, causing the left hand framing plate 18a to pivot around the pin 22, in the manner shown in Figure 3. As the framing plates 18a and 18b pivot with respect to each other -- only framing plate 18a moves in the circumstances considered above -- the ~hell 16 becomes slack, thereby permitting the frame members 14 to approach each other until they attain .
the position illustrated in Figure 3. Erection is, of course, a simple matter and is carried out in reverse; whereby, as shown 29 in Figure 3, the base member 12a is grasped and is swung through ;
an arc to the left. Obviously, as that operation continues, the shell 16 goes into tension between successive pairs of ~rame members, and as the arc motion of the base member 12a continues to the left, successive ones of the frame members 14 are pulled up until finally they achieve the erected position illustrated in Figure 1.
It is obvious that the folding shelter 10 may be erected and folded from either direction; that is, from the left to the right or from the right to the left, with no difference in the operation or achieved results. All of this is, of course, possible, because of the hinged relationship of the framing plates 18, and the manner in which the frame members 14 are each hingedly secured to the framing plates ].8, at a point further away from and lower than the last succeeding frame member, with regards to the centremost ~rame member.
As noted in Figure 6, when the folding shelter 10 is in its collapsed conditio~, at least when it has been first folded down or just prior to its erection, it occupies an area approximately one half of the area that will be occupied by the folding shelter when it is erected. In many instances, this matter is of no concern. However~ in some circumstances it may be desirable to reduce the area taken up by a folded shelter according to this .invention, and especially the~limits thereof.
To this end, especially when the base and frame members are substantially rectilinear in shape as those are according to the embodiments of the folding shelter that have been discussed so far and are illustrated, an improvement is further provided whereby each of the frame members is foldable across its width.
29 With reference to Figure 7, a frame member 14 is noted having a substantially centrally placed hinge 28. Because of the shape of the frame member -- substantially rectilinear, in the present discussion -- corner hinges 30 are also provided, to-gether with support braces 32 having stop lugs 34~ With reference to Figures 8 and 9, the manner by which the frame members 14 may be collapsed cross-wise is clearly shown.
That is, the braces 32 are unlocked, the corner hinges 30 are folded and the centrally located hinge 28 folds, all in the manner indicated by the arrows in Figures 8 and 9. By this manner, it will be seen especially from Figure 9 that the wldth of the folded frame members is considerably less than when the folding shelter is in its erected state or as shown in Figure 6. Accordingly, taking advantage of the pliancy of the shell 16, the entire folding shelter may be folded and collapsed into a volume sufficiently small so that the collapsed folding shelter might fit into the trunk of an automobile.
It is evident that the configuration of the hoop-like frame members 14 and the base members 12 are most conveniently of the same rectilinear shape, for the most efficient use of space and the most efficient head room across the width of the folding shelter. Further, the frame members 14 may also be more semi-circular; and, indeed, so may the base members 12.
Suitable materials for construction of the frame of the folding shelter according to this invention include steel and aluminum, and it has been found that aluminum pipe and rod is particularly useful, of sufficient strength and lightweight. It is, of course, possible to weld the base members 12 to the framing plates 18, when both are of the same material, whether steel 29 or aluminum. ~8-' ' - .

112~7S~
There has been describ~d a folding shelter, which may be usefull for both recreational purposes and for protection of workmen from inclement or adverse weather conditions, and which is of lightweight and simple construction so that it may be portable and easily collapsed. Suitable materials have been discussed, both for purposes of the frame, and the shell.
When the base members are not secured to the framing plates, it is necessary to otherwise provide for the hinging relationship of the framing plates to one another; which may be provided simply by the jamming action of the base and frame members against one another, but is more conveniently provided by a handle on the framing plates. As noted, however, the more convenient manner is by securing the base frames to the framing plates.
Also, as noted, the hinging relationship of the centre-most -- or one of them -- frame member to the hinging of the framing plates assures the collapslng and erecting action in a single motion.
Other alterations and embodiments are, of course, capable of production, especially depending upon the size of area to be covered by an erected folding shelter according to this invention, and the number of hoop-like frame members may be changed --although it is best for there to be an odd number of such members -- without departing from the spirit and scope of the appended claims.

DESCRIPTION OF THE PREFERRED EMBODIMENTS:
As noted, the principal purpose of this invention is to provide a folding shelter which may be ~sed either for camping purposes -- e.g., either to protect persons camping outdoors, or their belongings -- or for a shelter in which supplies or equipment may be stored for protectlon against the weather, or within which work may be carried out. This latter feature is particularly helpful in areas of extreme climate, where relatively light work such as roofing, certain kinds of telephone and electrical work, etc., might be carried out under a shelter according to this invention but not otherwise because of exposure to the elements and weather.
The folding shelter 10 of Figure 1 comprises two base members 12 and a plurality of hoop-like frame members 14. In the particular embodiment illustrated - a folding shelter having a base area approximately 2.5 meters x 3.5 meters -- the frame members 14 are designated as 14a, 14b, 14c, 14d and 14e; and the base members are designated 12a and 12b.
A shell 16 is supported by the frame members 14; and is secured around its edges -- at the bottom of the shelter -- to the base members 12 by snap fasteners 15 or other suitable fastening means.
The shell 16 may be made of fabric, for example canvas or 29 nylon, or other suitable pliant material such as rubberized -7~4 materials, fibre glass reinforced vinyl, etc.
Se~eral features of the shelter, particularly as it is shown in Figure 1 as it may be presented ~or purposes of camping and the like, are a ventillation opening 17 having net or screen covering 19 and a rollable cover 21 secured in its up position by tabs 23 and its down position by tabs 25. Also, there is a closable entrance flap 25 which may be opened and closed at zippers 27 and 29; and it will be noted that the entrance flap 25 is located so as to be positioned between the side portions of the hoop-like frame members 14b and 14c. Also, as noted in Figure 5, the shell 16 may be removably secured to the frame members 14 by means of a tab 29 and dome fastener 20.
Turning now to the features of the construction, particularly as they relate to the foldability of the folding shelter of this invention, it is noted that there are a pair of framing plates 18 which overlap each other, creating an overlapped area 20. The framing plates 18 are hinged together by a pin 22 which may have a cap 24 placed over one end. The positioning of the pin 22 is such that it is near the top of the overlapped area 20 It will also be noted that the centre-most hoop-like frame member 14c is hingedly secured to the framing plates 18 by the same pin 22.
The remaining hoop-like frame members 14a, 14b, 14d and 14e are also each hingedly secured at their ends to a respective one of the framing plates 18 by pins 24. Each attachment of a framing 14 to a framing plate 18 is such that each succeeding frame member away from the centre-most frame member 14c is 29 connected to the respective framing plate 18 at a point lower ~L~Z~754 and further away from the pin connection of the last succeeding frame member. For example, with reference to Figure 2, it is noted that the connection of frame member 14d to the right hand framing plate 18 (as viewed) is lower than the connect~on of the frame member 14c; and the connection of frame member 14e i5 lower than the connection of frame member 14d, and further away from the pin 22.
Reference is now made to Figure 3, showing the folding shelter 1~ in its folded condition. It will be seen that the framing plates 18 have changed their relative posi-tion to one another such that the framing plate designated 18a has moved from the position illustrated by the chain line in Figure 3 to the ~olded positi~n .illustrated, and as shown by the arrow 26. The manner in which the ~hell 16 has ~olded between the rame members 1~ is also noted.
As mentioned above, when the base members 12a and 12b -are secured to the respective framing plates 18a and 18b, then it is a very simple matter to erect or collapse the folding - shelter simply by manipulating.one or the other of the base members 12. For example, the left.hand ~ase member 12 (as seen in Figure 1) may be picked up, causing the left hand framing plate 18a to pivot around the pin 22, in the manner shown in Figure 3. As the framing plates 18a and 18b pivot with respect to each other -- only framing plate 18a moves in the circumstances considered above -- the ~hell 16 becomes slack, thereby permitting the frame members 14 to approach each other until they attain .
the position illustrated in Figure 3. Erection is, of course, a simple matter and is carried out in reverse; whereby, as shown 29 in Figure 3, the base member 12a is grasped and is swung through ;
an arc to the left. Obviously, as that operation continues, the shell 16 goes into tension between successive pairs of ~rame members, and as the arc motion of the base member 12a continues to the left, successive ones of the frame members 14 are pulled up until finally they achieve the erected position illustrated in Figure 1.
It is obvious that the folding shelter 10 may be erected and folded from either direction; that is, from the left to the right or from the right to the left, with no difference in the operation or achieved results. All of this is, of course, possible, because of the hinged relationship of the framing plates 18, and the manner in which the frame members 14 are each hingedly secured to the framing plates ].8, at a point further away from and lower than the last succeeding frame member, with regards to the centremost ~rame member.
As noted in Figure 6, when the folding shelter 10 is in its collapsed conditio~, at least when it has been first folded down or just prior to its erection, it occupies an area approximately one half of the area that will be occupied by the folding shelter when it is erected. In many instances, this matter is of no concern. However~ in some circumstances it may be desirable to reduce the area taken up by a folded shelter according to this .invention, and especially the~limits thereof.
To this end, especially when the base and frame members are substantially rectilinear in shape as those are according to the embodiments of the folding shelter that have been discussed so far and are illustrated, an improvement is further provided whereby each of the frame members is foldable across its width.
29 With reference to Figure 7, a frame member 14 is noted having a substantially centrally placed hinge 28. Because of the shape of the frame member -- substantially rectilinear, in the present discussion -- corner hinges 30 are also provided, to-gether with support braces 32 having stop lugs 34~ With reference to Figures 8 and 9, the manner by which the frame members 14 may be collapsed cross-wise is clearly shown.
That is, the braces 32 are unlocked, the corner hinges 30 are folded and the centrally located hinge 28 folds, all in the manner indicated by the arrows in Figures 8 and 9. By this manner, it will be seen especially from Figure 9 that the wldth of the folded frame members is considerably less than when the folding shelter is in its erected state or as shown in Figure 6. Accordingly, taking advantage of the pliancy of the shell 16, the entire folding shelter may be folded and collapsed into a volume sufficiently small so that the collapsed folding shelter might fit into the trunk of an automobile.
It is evident that the configuration of the hoop-like frame members 14 and the base members 12 are most conveniently of the same rectilinear shape, for the most efficient use of space and the most efficient head room across the width of the folding shelter. Further, the frame members 14 may also be more semi-circular; and, indeed, so may the base members 12.
Suitable materials for construction of the frame of the folding shelter according to this invention include steel and aluminum, and it has been found that aluminum pipe and rod is particularly useful, of sufficient strength and lightweight. It is, of course, possible to weld the base members 12 to the framing plates 18, when both are of the same material, whether steel 29 or aluminum. ~8-' ' - .

112~7S~
There has been describ~d a folding shelter, which may be usefull for both recreational purposes and for protection of workmen from inclement or adverse weather conditions, and which is of lightweight and simple construction so that it may be portable and easily collapsed. Suitable materials have been discussed, both for purposes of the frame, and the shell.
When the base members are not secured to the framing plates, it is necessary to otherwise provide for the hinging relationship of the framing plates to one another; which may be provided simply by the jamming action of the base and frame members against one another, but is more conveniently provided by a handle on the framing plates. As noted, however, the more convenient manner is by securing the base frames to the framing plates.
Also, as noted, the hinging relationship of the centre-most -- or one of them -- frame member to the hinging of the framing plates assures the collapslng and erecting action in a single motion.
Other alterations and embodiments are, of course, capable of production, especially depending upon the size of area to be covered by an erected folding shelter according to this invention, and the number of hoop-like frame members may be changed --although it is best for there to be an odd number of such members -- without departing from the spirit and scope of the appended claims.

Claims (5)
1. In a folding shelter having a plurality of hoop-like frame members and a shell made from fabric or other pliant material; where two of said hoop-like frame members are base members adapted to rest against the supporting surface on which said folding shelter is to be erected, the edges of said shell being secured to said two base members; and where there is at least one further hoop-like frame member supporting said shell; the improvement comprising:
a pair of framing plates centrally located on each side of said shelter and slightly overlapping each other, said plates being hingedly connected to each other by a pin connection placed near the top of the overlapped area of each;
each said further hoop-like frame members which support said shell being hingedly connected at each end to one of said framing plates, except the centre-most of said hoop-like frame members which is hingedly connected to both said framing plates at said pin connection between them;
any other of said hoop-like frame members being hingedly connected to said framing plates in such a manner that each succeeding frame member away from said centre-most member is connected to the respective framing plate at a point lower and further away from said pin connection than the last succeeding frame member.
a pair of framing plates centrally located on each side of said shelter and slightly overlapping each other, said plates being hingedly connected to each other by a pin connection placed near the top of the overlapped area of each;
each said further hoop-like frame members which support said shell being hingedly connected at each end to one of said framing plates, except the centre-most of said hoop-like frame members which is hingedly connected to both said framing plates at said pin connection between them;
any other of said hoop-like frame members being hingedly connected to said framing plates in such a manner that each succeeding frame member away from said centre-most member is connected to the respective framing plate at a point lower and further away from said pin connection than the last succeeding frame member.
2. The folding shelter of claim 1 where each of said two base members is secured at each end to one of said framing plates.
3. The folding shelter of claim 1 where said shell is releasably secured to said hoop-like frame members by tabs.
4. The folding shelter of claim 1 where each of said hoop-like frame members is centrally hinged and has support braces at its outer corners, so as to be foldable across its width.
5. The folding shelter of claim 4 where said hoop like frame members are substantially rectilinear in shape, and are hinged at their corners.
