BACKGROUND This invention relates to a suspended structure. More particularly, this invention relates to a suspended structure which can be made and erected using a simple frame member or members and one or more horizontally suspended platforms.

There is an ever pressing need for residential and commercial structures that can be erected economically preferably using prefabricated modules without sacrificing aesthetic and quality standards. The present invention provides such a structure.

SUMMARY In its broadest aspect, the suspended structure of the invention comprises elevated platform means attached to compression frame means and tension cable means anchored at points above and below said structure inclining the compression frame means at an acute angle from the vertical and suspending the platform means in a horizontal position. The tension cable means anchored at points above and below the structure run to the apex of the compression frame means. Where the compression frame means is attached to the rearward portion of the platform means, the platform means is horizontally suspended by the tension cables running from below the structure to the apex of the compression frame means. In this embodiment additional cable means anchored at points below the structure cross and are attached to rearward portions of the platform means, preferably at the points of attachment with the compression frame means to minimize stresses.

Where the compression frame means is attached to the forward portions of the platform means, the platform means is horizontally suspended by crossing tension cable means anchored at points above the structure and running to opposite points of attachment with the rearward portions of the platform means.

In a preferred embodiment upper and lower platform means, preferably trapezoidal in shape, are provided attached at respective forward and rearward portions thereof to the compression frame means, each horizontally suspended as described above. Additional bracing cable means running approximately from the base of the compression frame means can also be utilized as described herein in greater detail.

In a preferred embodiment of the invention the suspended structure comprises upper and lower platform means, A-frame means inclined at an acute angle from the vertical attached to the forward portion of the upper platform means and the rearward portion of the lower platform means, upper and lower spaced apart anchoring means, upper tension cable means attached to the upper anchoring means in pairs, one member of each pair being attached approximate the apex of the A-frame means, the other members crossing and being attached to opposite rearward portions of the upper platform means and lower tension cable means attached to the lower anchoring means in pairs, one member of each pair being attached to the apex of the A-frame means and the forward portion of the lower platform means, the other members crossing and being attached to opposite rearward portions of the lower platform means.

DESCRIPTION OF THE DRAWING The present invention will be more fully understood from the following description taken in conjunction with the accompanying drawing wherein:

FIG. 1 is a front view in elevation of a preferred suspended structure according to the present invention;

FIG. 2 is a top plan view showing the relationship between the upper and lower platforms of the preferred suspended structure of FIG. 1.

FIG. 3 is an upper rear and side view taken in perspective of the preferred suspended structure of FIG.

FIG. 4 is a lower side and front view taken in perspective showing the preferred suspended structure of FIG. 1; and

FIG. 5 is a side view in elevation of the preferred suspended structure of FIG. 1.

DESCRIPTION Turning now to the preferred suspended structure illustrated in the drawing, the suspended structure of the invention is shown to include an upper platform 12 and a lower platform 10. As shown in FIG. 2, the platforms 10 and 12 are preferably trapezoidal in shape and are positioned such that the upper platform is offset to the rear of platform 10. This is an inherent characteristic of the suspended structure wherein upper and lower platforms are provided and attached to the A-frame as shown in the drawing. Again with reference to FIG. 2, the

corners

76, 78, and 82 of the preferred trapezoidal shaped lower platform 10 form preferred points of attachment with the Aframe and cable members described in greater detail below. The upper platform I2 has similar points of

attachment

74, 84, 86 and 88 at the corners thereof.

A-frame 14 is inclined at an acute angle from the vertical (FIG. 5). The bases of the

A-frame

14,68 and 70, rest on and are preferably firmly attached to a supporting foundation which can be natural or man-made.

The A-frame 14 is attached to the forward portion of the upper platform 12 at

points

88 and 86 and is at tached to the rearward portion of the lower platform 10 at

points

82 and 76.

Anchoring devices are positioned at spaced apart points 60 and 62 above the suspended structure and at points 64 and 66 below the structure.

Upper cable members are attached to the upper anchoring devices 60 and 62 in pairs. One member of each pair, 38 and 42 in the drawing, is attached approximate the apex 72 of the A-frame 14. As shown in the drawing, the two

upper cable members

38 and 42 are somewhat bowed or sagged. This is an intentional preferred feature induced during erection which enables the suspended structure to more efficiently absorb externally applied stresses thereby remaining rigid. The most commonly encountered stresses are due to the force of wind and roof loads such as snow.

The other members of the

upper cable members

40 and 44 extend from the anchoring points or devices 60 and 62 and cross and are attached to opposite rearward portions ofthe upper platform 10. In the preferred embodiment the

cables

40 and 44 cross and are attached to

opposite corners

74 and 84 of the upper platform 12. The

cables

40 and 44 can be attached at their crossover point 33, if desired.

Lower cable members are attached to the lower anchoring points or devices 64 and 66 in pairs. One member of each pair, cables 30 and 36 are attached approximate the apex 72 of the A-frame l4 and are attached to the forward portion of the lower platform 10, for example at points or

corners

78 and 80. The

other cable members

32 and 34 attached to the lower anchoring points or devices 64 and 66 cross each other and are attached to opposite rearward portions of the lower platform 10, for example the points or

corners

76 and 82 of the lower platform 10. Again, the

cables

32 and 34 can be attached at their point of intersection 33, if practical and/or desired.

The

crossing cable members

32 and 34 are preferably attached to the lower platform at the points of

attachment

76 and 82 with the A-frame 14. This is a preferred manner of attachment which minimizes stresses. However, it should be understood that the

crossing cables

32 and 34 can be attached adjacent or within the general region of the

points

82 and 76 without impairing the structural integrity of the structure of the invention.

In addition to the upper and lower cable members strung from the upper and lower anchoring points or devices, it is preferred to use additional bracing cables attached to the bases 68 and 70 of the A-frame 14. One set of such bracing cables are

cables

46 and 50 attached to the bases 68 and 70 of the A-frame l4 and the forward portions of the lower platform 10 preferably at points of

attachment

78 and 80 which are common with the points of attachment between lower cables and 36 and the lower platform 10.

Another set of bracing cables are

cables

48 and 52 which extend from the bases 68 and 70 of the A-frame 14 to the rearward portions of the upper platform 12.

Cables

48 and 52 are preferably attached to upper platform 12 at

points

74 and 84 which are common with the points of attachment between

upper cable members

40 and 44 and upper platform 12.

lt is preferred for economy in design and construction and to minimize stresses that the points of attachment between the platforms, the A-frame and the various cables, be as common as is practically possible. In other words, the points of attachment are confined to a small area or a single point but can be adjacent to one another or in the same general area. Conventional means for attaching the A-frame, the upper and lower platforms and the various cables to one another can be employed. For example, any type of bolted or clamped device can be used to securely fasten the component parts of the suspended structure at their respective points of attachment.

The upper and

lower anchoring points

60, 62, 64 and 66 can utilize conventional anchoring devices such as pin, pipe, or bar members and the like with hook, eye or clamping means. Such members or similar devices can be driven into holes drilled into the supporting terrain utilizing the holding power of the terrain itself in the case of rock or additional supporting sub-structures can be used for the anchoring devices such as poured concrete foundations at the respective anchoring points.

As shown in FIG. 1, the upper and lower anchoring points are preferably vertically aligned with the bases of the A-frame 14. However, the spacing and positioning of the upper and lower anchoring points can be altered to meet varying terrain contours and conditions.

With reference to FIG. 5, the A-frame 14 is preferably inclined at an acute angle from the vertical such that the A-frame 14 is perpendicular to a line drawn between upper and lower anchoring points 62 and 64 respectively. However, the angle of inclination of the A- frame 14 can vary to meet or accommodate terrain contours and/or design features vis-a-vis the enclosure for the suspended structure.

The essential components of the suspended structure of the invention, namely the frame, the platform or platforms and the various cables, can be made from conventional materials of construction. For example, the A-frame 14 can be suitably made from steel pipe, 12 inches in diameter and the various cable members can be made from steel cable 1 inch and 1 V2 inches in diameter. The A-frame can be made from other conventional materials such as laminated wood members or structural steel members. The various cable members can also be replaced partly or completely by metal rod members. For example, the bracing cables extending from the bases of the A-frame could be made of rigid metal rods or bars while the upper and lower suspending and supporting cable members can be made of strand steel cable. It should be understood that the term cable as used herein is intended to generically define any linear supporting and suspending member such as cables, rods and bars.

The frame 14 can also be made of prefabricated steel reinforced concrete members. The platforms l0 and 12 can also be made of steel reinforced concrete slabs prefabricated in the desired shape. Other known materials of construction such as laminated, composite or honey comb structures can be used to prefabricate slabs for the upper and lower platforms. The platforms themselves as indicated herein are preferably trapezoidal in shape. However, other shapes such as round and/or polygonal shapes can also be utilized. It should be understood that the respective platform members 10 and 12 can extend beyond the configuration shown in the drawing such that the A-frame 14 and the various cable members pass through and are attached to adjacent inboard portions of the respective platforms l0 and 12. Various extensions of the upper and/or lower platform members can be utilized to provide exterior deck space for the suspended structure or additional interior space.

As pointed out previously, the suspended structure of the invention can be erected with platform 10 in which

case cables

40 and 44 could be eliminated or attached to points 76 and 82. The structure can also be erected with a single platform such as upper platform 12 attached at its forward portion to the A-frame 14. It is also possible to use a single platform wherein the A- frame 14 passes through the central portion of the sides thereof and the forward and rearward portions of the platform are suspended horizontally via the cable members described herein for suspending the upper and lower platform members 12 and 10, respectively. More than two platforms can also be incorporated into the suspended structure of the invention to provide for a multilevel structure. For example, in FIG. 5 an additional platform or platforms could be attached and suspended in the same manner as the lower platform 10 above or below same. The same is true for additional platforms attached and suspended in the same manner as upper platform 12.

The suspended structure of the invention is ideally erected on a steeply sloped rocky terrain. Where the terrain is less steeply sloped, the upper anchoring points 60 and 62 can be built-up to the desired height from which the upper cable members are-to be sus pended. Thus, towers or similar such structures can be utilized to hang or suspend the upper cable members from the upper anchoring points 60 and 62.

The suspended structure of the invention can be enclosed in a number of ways to suit the use intended for the suspended structure. The enclosure for the suspended structure of the invention shown in the drawing is by way of example only and is not intended to limit the invention in any way. In the drawing a suitable enclosure for using the suspended structure as a residence is illustrated and includes appropriately located mullions 98 defining a portion of the structure enclosed by glass panels 102. Surrounding the glass enclosed portion is a solid panel enclosure utilizing panel member 100 as illustrated. As shown in FIGS. 3, 4 and 5, rearward portions of the structure can also'be enclosed in glass. An enclosure can be suspended from

upper cables

38 and 42 at

points

90, 92, 94 and 96 and points intermediate thereof. The mullions 98 defining the glass enclosed portion can also be replaced by a continuous cable member which runs from point 78 on the lower platform to point 88 on upper platform 12 and then to point 90, point 92 back down to point 86 onthe upper platform 12 and finally ending at point 80 on lower platform 10. The enclosure for the suspended structure can be suspended from and attached to the various parts thereof using conventional attaching devices such as bolts, rivets, clamps and the like.

Entry ways for ingress and egress can be located at any desired site. For example a tower containing a spiral staircase or elevator can extend from below the lower platform 10 and extend upward therethrough. Access can also be had by means of a tunnel-shaped structure extending through the rear of the enclosure to the space above the upper platform 12. Such a structure is indicated in FIGS. 1 and 2 by reference numeral 103 and is suitably supported by being suspended from the upper cable members, or platform of the structure, or from the ground.

Utility lines and waste removal conduits can be suitably located in the base or floor of the tunnel structure 103, in the interior of the legs of the A-frame member 14 or in the tower structure extending through the lower platform 10 as described previously.

The suspended structure of the invention also makes it possible to erect a multi-level structure involving a series of vertically aligned A-frames with platforms and supporting cables as described herein, said structures being interconnected by suitable tower, elevator and tunnel structures. It is thus possible to construct an entire community having suspended structures suited for all aspects of public and private life, said structures being constructed from inclined frame members, horizontal platforms supported and suspended by a system of cables as described herein and interconnected by suitable elevators, towers, tunnels, tramways, cable cars and the like.

In such structures, relatively simple and/or complex compression frame means can be employed for single or multi-level suspended structures having platform means with the same, varying or different shapes. Suitable frame means can be terrain supported and/or radiate from one or more vertical towers or poles and can be H, l, M, T, U, V, W, X or Y-shaped as well as other symmetrical, simple and multi-sided shapes.
