Geodesic mold house
BACKGROUND OF THE INVENTION 
     The instant invention relates generally to prefabricated buildings and more specifically it relates to a geodesic mold house. 
     Numerous prefabricated buildings have been provided in prior art that are adapted to be assemblied together in specific segments. While these units may be suitable for the particular purpose to which they address, they would not be as suitable for the purposes of the present invention as heretofore described. 
     SUMMARY OF THE INVENTION 
     A principle object of the present invention is to provide a geodesic mold house that will overcome the shortcomings of the prior art devices. 
     Another object is to provide a geodesic mold house whereby in its final fabrication one hardened outer shell is superimposed upon another shell with a space inbetween for insulation. 
     An additional object is to provide a geodesic mold house that utilizes reinforcements rods and plates for added strength. 
     A further object is to provide a geodesic mold house that is simple and easy to use. 
     A still further object is to provide a geodesic mold house that is economical in cost to manufacture. 
     Further objects of the invention will appear as the description proceeds. 
     To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIG. 1 illustrates a geodesic mold house 10 that consists of an inner flexible dome like shell 12 having a plurality of wall segments 14, inflatable ribs 16, indents 18 and a built-in door segment 20. 
     A coat of hardening material 22 is sprayed over the wall segments 14 and door segment 20 of the inner shell 12 to retain shape of the inner shell. 
     An outer firm dome like shell 24 having a plurality of detents 26 and being of the shape of the inner shell 12 is placed over the inner shell. The detents 26 will engage with the indents 18 creating a space 28 inbetween the shells for insulation through which windows 30 can be cut out through the shells. 
     A plurality of rods 32 are provided. FIG. 3 shows one of the rods 32 placed within one of the inflatable bottom ribs 16a of the inner shell 12 for weight so that the bottom rib 16a can be recessed securely within a ditch 34 in the ground 36. 
     As shown in FIGS. 1 and 2 the built-in door segment 20 has a C-shaped inflatable rib 16b which is inflatably hinged at 38, at upper and lower portions 40, to one of the inflatable vertical ribs 16c on one of the wall segments 14 so that the door segment 20 can open and close. 
     As shown in FIGS. 1 and 4 a curved stop member 42 is vertically connected to one of the inflatable vertical ribs 16d. The vertical portion 44 of the C-shaped rib 16b will engage with the stop member 42 when the door segment 20 is closed. 
     FIGS. 5 and 6 show a modified geodesic mold house 50 which consists of an inner flexible bag like shell 52 having a plurality of wall segments 54 and inflatable ribs 56. 
     A first coat 58a of hardening material is sprayed on the wall segments 54 of the inner shell 52 to retain shape of the inner shell. 
     A first set of reinforcement rods 60a for reinforcing the wall segments 54 of the inner shell 52 are placed onto the first coat 58a of hardening material. 
     A second coat 58b of hardening material is sprayed on the wall segments 54 of the inner shell 52 so that the reinforcement rods 60a will be within the hardening materials to add strength thereto. 
     An outer flexible bag like shell 62 is also provided and has a plurality of wall segments 64 and inflatable ribs 66 being of the shape of the inner shell 52. The outer shell 62 is placed around the inner shell 52 so that a space 68 is created inbetween the shells for insulation. 
     A third coat 58c of hardening material is sprayed on the wall segments 64 of the outer shell 62 to retain shape of the outer shell. 
     A second set of reinforcement rods 60b for reinforcing the wall segments 64 of the outer shell 62 are placed onto the third coat 58c of hardening material. 
     A fourth coat 58d of hardening material 16 sprayed on the wall segments 64 of the outer shell 62 so that the reinforcement rods 60b will be within the hardening materials to add strength thereto. 
     In FIG. 7 a plurality of reinforcement plates 70 and a plurality of tie down strips 72 therebetween are used instead of the reinforcement rods 60a and 60b. 
     While certain novel features of this invention have been shown and described and are pointed out in the annexed claims, it will be understood that various omissions, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing from the spirit of the invention.
