FQLDABLE AND PORTABLE AmCRAFT SHELTER Murville E. Tang, Los Angeles, Calif. Application January 5, 1953, Serial No. 329,585

11 Claims. ((Il. 135-1) This invention relates to foldable and portable aircraft shelters, and more particularly to a shelter structure of the character referred to which is designed preferably for use for a single airplane,'and which can be anchored to the ground, after being set up, so as to be securely held in place while in use.

Among the salient objects of the invention are:

To provide a foldable and portable aircraft shelter which is economical to manufacture, simple and convenient to set up, or to take down and fold into a compact form for transportation from place to place;

To provide such a shelter which can be anchored to the ground, or to a special foundation built therefor, by means of cables or chains, in order to be firmly held in place for use;

To provide a shelter of the character referred to which can be folded into small compass with carrier wheels, which, when thus folded for movement from one place to another, will be in good operating position for supporting and carrying one end of the pack.

Other objects and advantages of the invention will be apparent from the following more detailed description of one practical embodiment of the invention, taken with the accompanying two sheets of drawings, in which:

Figure 1 is a plan view looking down upon a shelter structure embodying the invention, in its set up form, with an airplane indicated in light broken lines, and with a part of the covering broken away;

Figure 2 is a front view thereof, without the covering;

Figure 3 is a perspective view of the frame structure, with the anchoring wires and cables, taken from a position to one side and above the structure;

Figure 4 is a view showing the main frame members folded together in a bundle, ready for movement;

Figure 5 is a rear view of the frame members folded for towing;

Figure 6 is a fragmentary view of the upper front ends of the frame, showing a pivoted short arm, normally down in full lines, but which can be moved rearwardly, or swung up and over in reversed position, end for end, as seen in the uppermost light line position.

Referring now in detail to the drawings, two

A-frame members

7, 7, are shown hinged together at their upper ends, as at 8, Figs. 1 and 2, with their lower ends provided with base plates or blocks, as at 7', 7'. When set up for use, said

A-frarne members

7, 7 constitute a central A support for the structure, as will be understood from Fig. l.

Pivotally connected at their lower ends, to the lower ends of said

A-members

7, 7, are two forwardly, upwardly and outwardly extending arms or members, 9, 9. Said pivotal connections are indicated at 10, 11), Figs. 1 and 2. Aflixed at each of said connections is a leg which extends at an angle from the frame member 7 and is provided with a small carrier wheel, as 11, so that when said members are folded together, as seen in Figs. 4 and 5, said wheels will be in position for towing said bundle.

r were I Patented Jan. 22, 1957 Two short limit chains, as 12, 12, connect said legs 10, 10', with the

frame members

7, 7, Fig. 2. Said

frame members

9, 9, are provided adjacent their outer ends with rigid angle members, as 13, 13, preferably made of fiat iron, to form bearing members for anchoring and cover supporting cables, as will be later described.

Pivotally connected to the two

A-frame members

7, 7, adjacent their hingedly connected ends, are two forwardly extended arms or members, 14, 14, connected at their outer ends, as by a pivot pin or bolt 15, which bolt serves as a bearing support for a short arm 16, having thereon a loop member 17, attached at its ends to said arm 16, and formed into an inclined V-loop through which said pivot pin or bolt 15 passes, so that it is possible for said short arm 16 to be moved rearwardly from the position seen in full lines in Fig. 6, to the lower position shown in light broken lines, or it can be swung upwardly and over to a reversed end for end position, for a purpose to be later described. A small pulley 16' is mounted on one end of said arm 16, to bear and move on the underside of a combined cover supporting and anchoring cable 22, as shown in Fig. 6. The other end of the arm 16 has attached thereto a pair of cover

engaging cables

18, 18, extended in opposite directions and aflixed at their outer ends to the upper ends of the two

frame members

9, 9, as at 9, 9. Said

cables

18, 18, also have as apart thereof a coiled spring section 18', to provide a certain yieldableness thereto so that it will be possible for the free end of said short arm 16 to be swung upwardly and over to the reversed position, indicated by the uppermost light broken line position in Fig. 6.

Cover supporting and tie cables or

chains

19, 19, are fixedly attached to the outer ends of the two

frame members

14, 14, where the latter are connected to each other, by suitable connections 19, 19', said cables or chains extending in opposite directions and being aflixed at their outer ends to the upper ends of the

frame members

9, 9, as by connections 9, 9'. Guy wires 19 attached to the outer ends of the

frame members

9, 9, by connections 9", 9", lead down and are ailixed to anchor

eyes

20, 20, in the ground or foundation on which the structure rests.

A pair of cover engaging and tie cables or

chains

21, 21, are fixed at one of their ends to and extend from the rearward ends of the two

arms

14, 14, as indicated at a, a, and leading in opposite directions are alfixed to the

angle members

13, 13, by connections b, b, from which connections guy wires 21, 21', lead and are affixed to the

anchoring eyes

20, 20, as shown in Figs. 1 and 2.

A central cover supporting and anchoring cable 22, before referred to, is alfixedly connected at one end thereof to the upper ends of the joined

frame members

14, 14, by a connection 0 and is extended rearwardly over and seated upon the upper hinged ends of the

members

7, 7, of the A-frame, and is thence continued down to the ground or foundation and atfixed to an anchor eye 23.

A tie cable or chain 25 lying near the ground is afiixed at its ends by connections a, d, to the lower ends of the

legs

7, 7, adjacent the base plates 7 7 to limit spreading of the legs 77, and leading from and affixed to the lower ends of the

legs

7, 7, by the connections d, d, are

guy wires

25, 25, which are affixed at their outer ends to the

eyes

20, 20, to hold the f t-frame against rearward movement.

After the frame structure has been set up and anchored as described, canvas or other covering material, designated C, is spread over the top of the structure, and tied to the wires or cables, as at 24, 24. With said covering extended forwardly and over cable 19, and down to cable 18, in the front of said structure, and tied to said wires or cables, it forms a shade down to the end of the short arm 16, to which it is attached. By providing the spring 7 6, thusraising the covering attached to-.saidcable-.18, out

of, the wayand giving clearance in thefront of the-structure for a plane tobe moved intoor out of said shelter.

While I have shown and described my shelter as foldable for moving purposes, andhave, therefore,- made the A-frame members and the different forwardly extended arms or members hingedly or. pivotally connected, it is evident that a supporting frame structure of the, same character could be made rigid, that is: withsaid members rigidly secured together. in the same positionaandldo not limit the invention to the details of, construction and arrangement shown for purposes of description and explanation, except as I may be limited by thehereto appended claims forming a part of this application.
