Description:
BACKGROUND OF THE INVENTION 
     1. Technical Field 
     The present invention is directed to load bearing scaffolds and more particularly to load bearing scaffolds adapted to derive at least some of their support from the interior surfaces of a room. 
     2. Description of the Prior Art 
     Load bearing scaffolds are well known in the construction arts. Such scaffolds are generally adapted for supporting workmen, construction equipment, and building materials. 
     Also known are bunks and berths adapted to provide sleeping accommodations for passengers, military personnel, students, or small children. These apparatus are often adapted to be supported from poles anchored to the floor and ceiling of a room. For example, apparatus of this general species are disclosed by Lein, U.S. Pat. No. 665,535; Rodrigues, U.S. Pat. No. 958,895; Gosso, U.S. Pat. No. 1,325,320; and Gosso, U.S. Pat. No. 1,089,545. 
     Also known to the art are bunks or berths adapted to be supported by anchoring the bunk or berth to a wall. For example, apparatus of this general species are disclosed by Lein, U.S. Pat. No. 669,175; Dowling, U.S. Pat. No. 822,592; Rodrigues, U.S. Pat. No. 860,941; Gumm, U.S. Pat. No. 1,001,946; Thompson, et al., U.S. Pat. No. 3,215,387; Coomes, U.S. Pat. No. 3,858,254; and Trexler, Jr., et al., U.S. Pat. No. 4,084,276. 
     Inventions of this type are unsuitable for the present objects since their installation requires that they become room fixtures. Additionally, such bunks or berths necessarily require the dedication of otherwise useful floor space. 
     Free standing bunk beds are also known to the bunk and berth art. Examples of this type of bed may be found disclosed by Lein, U.S. Pat. No. 631,962; Anderson, U.S. Pat. No. 1,195,637; Weaver, U.S. Pat. No. 1,253,549; and Janson, et al., U.S. Pat. No. 1,349,962. 
     Bunks or berths of this type are also incapable of performing the objects of the present invention in that they require otherwise livable space to be dedicated solely to their use. 
     3. Objects of the Invention 
     Many educational institutions provide dormitories in order to accommodate students who are required to live on campus. Dormitories are generally multistory buildings having a central elevator and stairway corridor. On either side of the central area is a hallway having a plurality of small rooms located on either side of the hallway. These small rooms generally do not have bathrooms. 
     Each room has a small closet and is usually furnished with two single beds, two desks, two lamps, two chairs, and a dresser or bureau. Even though each room contains a minimal amount of furniture, the rooms are small, and space is at a premium. 
     Since these rooms are small and sparse it is difficult for two people to live comfortably within the room. This is true since most dorm rooms lack sufficient space to maintain a stereo, television, small refrigerator, or to store a bicycle and the like. 
     Students desiring a more livable environment often remove their beds or make the existing two single beds into a lower and upper berth bunk bed. With the same goal in mind students also replace their beds with futon mattresses. 
     The primary object of the present invention is to provide an improved load bearing scaffold capable of dispersing load forces to the floor and other surfaces of a room. 
     Another object of the present invention is to provide a load bearing scaffold that does not require the scaffold to be attached to the room infrastructure or superstructure. 
     Another object of the present invention is to provide a load bearing scaffold that will not damage room surfaces. 
     Another object of the present invention is to provide a load bearing scaffold that is easy to assemble and disassemble. 
     Another object of the present invention is to provide a load bearing scaffold that is safe to use and durable in construction. 
     Another object of the present invention is to provide a load bearing scaffold that is low in cost and easy to manufacture. 
     Another object of the present invention is to provide an adjustable load bearing scaffold adapted to fit in any sized room. 
     Another object of the present invention is to provide a load bearing scaffold that frees existing floor space. 
     Finally, another object of the present invention is to provide a load bearing scaffold capable of supporting beds, desks, shelves, and the like. 
     SUMMARY OF THE INVENTION 
     The present invention provides a load bearing scaffold adapted to disperse load forces to interior room surfaces. The load bearing scaffold includes a pair of generally parallel telescopically adjustable horizontal beams. 
     The horizontal beams are supported on at least one end by at least one pair of generally parallel vertical beams. The vertical beams are interconnected in spaced apart relation by at least one cross bar. 
     The scaffold is adjustably assembled so that the vertical beams and cross bar abut against one wall while the horizontal beams abut against the ceiling and opposite wall. Articles may be supported by being suspended from the vertical beams or horizontal beams of the scaffold.

The hole 28 of each end of the assemblies (12 and 14) are adapted to threadably engage a fine adjustment bolt 30. Mounted to the end of each bolt 30 is a wall plate 32. Each wall plate has a rubberized wall pad 34 fixed thereto. 
     In a preferred embodiment the scaffold support apparatus 10 aIso includes a first vertical support beam assembly 36 and a second vertical support beam assembly 38. 
     Each vertical support assembly (36 and 38) consists of a pair of vertical support beams (40a, 40b, 40c, and 40d). Each vertical support beam 40 consists of a hollow guide post 42 and a hollow arm 44 adapted to slidably extend from and retract into the hollow guide post 42 (FIG. 1). 
     In a preferred embodiment the guide posts 42 are fabricated from 1.25 inch square tubing. The arms 44 are fabricated from 1.00 inch square tubing. The arms 44 have a plurality of spaced apart adjustment holes 46 formed therethrough. In a preferred embodiment the adjustment holes are spaced 4.00 inches apart. Also included are horizontal beam anchor holes 48 formed through the end of each guide post 42 and arm 44 (FIG. 2). Formed through the guide post 42 is an adjustment pin hole 50. 
     An arm 44 may be slidably engaged by a guide post 42 and a pin 50 may be passed through the adjustment pin hole 50 and an adjustment hole 46 so as to create a vertical support beam (40a, 40b, 40c, and 40d) of a particular length (FIG. 1). 
     Welded between the top and bottom ends of a first pair of vertical support beams 40a and 40b are a pair of first cross members 52a and 52b forming a first vertical support assembly 36. Welded between the top and bottom ends of a first pair of vertical support beams 40c and 40d are a pair of first cross members 52c and 52d forming a second vertical support assembly 38. 
     The first 36 and second 38 vertical support assemblies are utilized to vertically support the first 12 and second 14 horizontal beam assemblies. FIG. 2 illustrates a preferred apparatus for anchoring the horizontal beam assemblies (12 and 14) to the first 36 and second 38 vertical support assemblies. 
     As is illustrated by FIG. 2 the vertical beam anchor holes 22 are matched with the horizontal beam anchor holes 48 and a pin 54 may then be used to anchor the vertical and horizontal assemblies together. 
     The bottom end of each of the vertical beams (40a, 40b, 40c, and 40d) is covered by an end plate 56 having a threaded hole 58 formed therethrough (FIG. 6). The hole 58 of each end of the vertical beams (40a, 40b, 40c, and 40d) is adapted to threadably engage a fine adjustment bolt 60. Mounted to the end of each bolt 60 is a wall plate 62. Each wall plate has a rubberized wall pad 64 fixed thereto. 
     A bed support assembly 66 may be connected to each of the vertical support assemblies (36 and 38). Each bed support assembly 66 consists of a first telescoping horizontal bar assembly 68 and a second horizontal bar assembly 70. Both the first 68 and second 70 horizontal bar assemblies have a hollow guide post 72 and a hollow arm 74 adapted to slidably extend from and retract into the hollow guide post 72 (FIG. 4). 
     In a preferred embodiment the guide posts 72 are fabricated from 1.25 inch square tubing. The arms 74 are fabricated from 1.00 inch square tubing. The arms 72 have a plurality of spaced apart adjustment holes 76 formed therethrough. In a preferred embodiment the adjustment holes are spaced 4.00 inches apart. Also included are vertical beam anchor holes 78 formed through the end of each arm 18 (FIG. 3). Formed through the guide post 72 is an adjustment pin hole 80. 
     An arm 74 may be slidably engaged by a guide post 72 and a pin 82 may be passed through the adjustment pin hole so and an adjustment hole 76 so as to create a horizontal bar assembly (68 and 70). 
     The ends of each of the horizontal bar assemblies are covered by an end plate 84 having a threaded hole 86 formed therethrough (FIG. 3). The hole 86 of each end of the assemblies (68 and 70) are adapted to threadably engage a fine adjustment bolt 88. Mounted to the end of each bolt 88 is a wall plate 90. Each wall plate has a rubberized wall pad 92 fixed thereto. 
     The opposing ends of a bed support cross bar 94 are welded on top of the end of any two guide posts 72 of the horizontal bar assemblies (68 and 70) (FIG. 4). The ends of each of the horizontal bar assemblies are covered by an end plate 96 having a threaded hole 98 formed therethrough (FIG. 4) The hole 98 of each end of bed support cross bar 94 is adapted to threadably engage a fine adjustment bolt 100. Mounted to the end of each bolt 100 is a support plate 102 having a cable hole 104 formed therethrough. 
     Each bed support assembly 66 may be suspended from a vertical support assembly 36 and 38 (FIGS. 3, and 4). As is illustrated by FIG. 3 a bed support anchor hole 106 formed through the vertical support beams (40a, 40b, 40c, and 40d) is matched with a horizontal bar anchor hole 108 and a pin 110 may then be used to anchor a bed support assembly 66 to a vertical support assembly (36 and 38). A cable 112 may then be mounted between vertical beam cable hole 114 and cable hole 104 (FIG. 4). 
     It is apparent that pins 24, 50, 54, 82, and 110 may be interchangeable. Likewise, the wall pad support assemblies and feet are also interchangeable. The entire structure may be powder coated or protected by a layer of paint. 
     While the invention has been described with a certain degree of particularity, it is manifest that many changes may be made in the details of construction and the arrangement of components without departing from the spirit and scope of the disclosure. For example, the apparatus may be adapted to support desks, shelves, planters, bicycles, televisions, or stereos. 
     It is understood that the invention is not limited to the embodiments set forth herein for purposes of exemplification, but is to be limited only by the scope of the attached claims including the full range of equivalency to which each element thereof is entitled. 
     Thus, there has been shown and described a support structure for beds and the like which accomplishes at least all of the stated objects.
