referring now to the drawing , where like reference numerals indicate like elements , fig1 through 16 show the separate component elements of the present invention that , when assembled together in any desired array , configuration and order , will depict a space ship or space station , as for example , shown , respectively , in fig1 and 18 . to first summarize all of the component elements before describing in detail the structure and interconnections thereof , it is noted that the present invention provides six major component series that constitute the backbone of the present invention in that the sculptures or designs are built up therefrom . the present invention also provides a supplementary component series which include components having the shape of specific functional elements of a space craft or space ship , such as , for example , solar panels , heat radiators , antennae and the like , all of which are described below in greater detail . the present invention also provides a tertiary component series used for connecting some of the other components of the major and supplementary components series together , which tertiary series includes a number of tie pins or studs , described in greater detail below . each component series is herewith discussed . the first major component series of the present invention are what are termed the &# 34 ; engineering modules ,&# 34 ; and are shown in detail in fig1 a and 1b . each engineering module 10 is of a hollow cylindrical configuration having an annular surface 10 &# 39 ; in which are formed a plurality of holes 12 . the holes 12 are preferably formed about the circumference of the annular surface 10 &# 39 ; in groups of three , spaced 90 degrees apart , as substantially shown in fig1 a and 1b , though different arrangements of the holes may be provided . the holes 12 are used for attaching other component elements to be described below in greater detail . also , about the outer circumference of the annular surface 10 &# 39 ; are four hollow projecting sleeves 14 , preferably spaced 90 degrees apart about the circumference . the ends of the four sleeves 14 remote from the circumference of the annular surface 10 &# 39 ; are provided with interior threads serving as female connecting portions for other components to be described below in greater detail . the engineering module 10 has a first open end 16 that is a reduced diameter projecting cylindrical portion having exteriorly - formed threads about its outer circumference to serve as a male connecting projection . the engineering module also has a second open end 18 which is provided with interiorly - formed threads for forming a female - connecting element . thus , it is possible to connect a plurality of the engineering modules 10 together to form a linear array by screwing the first male end of each engineering module to a second female end of another engineering module . when a plurality of these engineering modules are thus connected together , they simulate the living and working spaces of a space station or space ship , while the sleeves 14 are meant to represent air locks for these living and working spaces . when having arranged a linear array of these engineering modules 10 , it is sightly to have the exposed , unattached ends of the last modules closed off or terminated . to this end , a plurality of engineering module terminator components 20 are provided , one of which is shown in fig2 a and 2b . the engineering module terminator component 20 has a main hollow ring - shaped portion 20 &# 39 ; having an open end with interiorly - formed threads to serve as a female mounting acceptor for mounting to the male end 16 of a last one of the engineering modules of a linear array . each terminator 20 is also provided with a hood or truncated conical portion 22 having a connecting sleeve 22 &# 39 ; projecting from its truncated end ( as shown in fig2 a and 2b ). the sleeve 22 is also interiorly - threaded to act as a female connector , so that the entire linear array may be connected at its end to other components described below . it is pointed out that since each of the engineering modules 10 has one male end and one female end , it will occur at one end of each linear array that a female end 18 is left unattached , which female end 18 still needs to be terminated by a terminator 20 . therefore , a plurality of end engineering modules are provided , one of which is shown in fig1 c . this end engineering module 24 , instead of having one female connecting end and one male connecting end , is provided with two male connecting ends , as shown , so that the unattached male connecting end may be screw - connected to a terminator 20 via a terminator &# 39 ; s female connecting end . in one form of the present invention , each engineering module may have an outer diameter of 4 inches , while each air lock or sleeve 14 has an outer diameter of 3 / 4 inches . the main cylindrical portion 20 &# 39 ; of the terminator 20 preferably has an outer diameter of 4 inches also , so that the slightly reduced male connecting ends of the engineering modules will screw therein . the sleeve 22 &# 39 ; of the terminator is also 3 / 4 of an inch in outer diameter . the length of each engineering module from end to end may vary from 1 to 3 inches . it is , of course , to be understood that the dimensions stated above and all dimensions stated hereinafter are given only for reference purposes and do not in any way constitute a limitation of the present invention . the dimensions may be changed to fit the requirements and needs of one skilled in the art . the second major component series are a plurality of connecting tubes , one of which is shown in fig3 . the connecting tube 30 is generally an elongated hollow cylindrical element having exteriorly - threaded ends 30 &# 39 ; to form male connecting ends . the surface of the connecting tube 30 is provided with a plurality of holes , preferably in the same manner as formed in each engineering module , so that there are four groups of three holes spaced 90 degrees apart about the circumference of the connecting tube , as shown in fig3 . the connecting tubes 30 generally are provided in two different diametric sizes : small diameter and large diameter sizes . the small - diameter connecting tubes 30 generally constitute the staple connecting tubes since they are connectable to the sleeves or air locks 14 of the engineering modules . thus , in one example of the invention , the outer diameter of these small - diameter connecting tubes is 1 / 2 inch to screw inside the female connecting end of a sleeve 14 . these small - diameter connecting tubes 30 also connect to the sleeves 22 &# 39 ; of the engineering module terminators 20 , so that linear arrays of engineering modules may be connected together via these small - diameter connecting tubes . the linear arrays of engineering modules 10 may be connected together so that the arrays are parallel to each other or at an angle to each other , which is described in greater detail below . the large diameter connecting tubes are , in the preferred form of the invention , used in special situations where a large - diameter tube is desired for special effects or design . a special coupling member , called a transition coupling step - up component , is provided to allow connection of the large - diameter connecting tube to the small - diameter connecting tube or to the sleeves 14 or to the sleeves 22 &# 39 ;, which step - up member will be described in greater detail below when discussing the third major component series . the length of each of the connecting tubes depends upon the diameter . thus , for the large - diameter connecting tubes , the length of the tube may typically be 6 inches with an outer diameter of the tube being 11 / 2 inches , while for the small - diameter connecting tube , the length thereof may be only 3 inches , with an outer diameter of only 1 / 2 inch . a shorter version of the small - diameter connecting tube is also provided , so that it has a total length of only 1 inch with an outer diameter of 1 / 2 inch . these shortened versions of the small - diameter connecting tubes are used for cross - attaching engineering modules via respective sleeves or air locks 14 of the engineering modules . these shortened versions allow for closer attachment of the linear arrays of engineering modules 10 together , whereas the longer versions of the small diameter connecting tubes allow for greater distancing of the linear arrays . the holes provided in the surface of each connecting tube also serve to allow attachment thereto of other component parts previously described and to be described below . the third component series are what are termed the &# 34 ; transition coupling elements ,&# 34 ; which are utilized to connect together the adjacent ends of connecting tube components , to provide a chain of such connecting tube components . these transition coupling elements are shown in fig4 a through 4e . in fig4 a , one of a number of straight coupling elements 32 is shown , which , as shown , is a hollow cylindrical sleeve member having interiorly - threaded ends to form female attaching parts for attachment to the male connecting ends of the connecting tube components . use of the straight coupling elements 32 provides a linear , coextensive extension of connecting tube components . one of another type of transition coupling elements is shown in fig4 b , and is a right - angle coupling element 34 having its respective interiorly - threaded open ends 34 &# 39 ; oriented at a right angle to each other , so that two connecting tube components 30 may be connected perpendicular to each other . one of still another type of transition coupling elements is shown in fig4 c , and is a 45 - degree angle element 36 where its interiorly - threaded open ends 36 &# 39 ; are oriented at a 45 degree angle to each other for connecting two components 30 at a 45 degree angle . one of still another type of transition coupling elements is shown in fig4 d , and is an &# 34 ; x &# 34 ;- junction coupling element 38 . in this coupling element , each of the four interiorly - threaded open ends 38 &# 39 ; is at a right angle to two adjacent open ends and faces oppositely to its distal end . this transition coupling elements 38 is used to connect four connecting tube components 30 together with each being perpendicular to adjacent ones . fig4 e shows still another type of transition coupling elements 40 which is a &# 34 ; y &# 34 ;- junction coupling element , where its interiorly - threaded open ends 40 &# 39 ; are spaced 120 degrees apart to form a &# 34 ; y &# 34 ; shape . each of the above - described transition coupling elements comes in two different diameter sizes , a small one to connect small - diameter connecting tubes , and a large one to connect large - diameter connecting tube components . in one form of the invention , when the small and large connecting tube components have outer diameters of 1 / 2 and 11 / 2 inches , respectively , the outer diameters of each of the interiorly - threaded open ends of transition coupling elements will be 3 / 4 of an inch and 13 / 4 inches , for the small and large transition coupling elements , respectively . an additional type of transition coupling elements is shown in fig7 a and 7b , which is called a &# 34 ; step - up &# 34 ; transition coupling adapter , for this type is used to interconnect a small - diameter connecting tube component with a large - diameter connecting tube component as previously described . to this end , each &# 34 ; step - up &# 34 ; transition coupling adaptor 42 includes a large - diameter ring - shaped portion 44 with an interiorly threaded open end 44 &# 39 ; for receiving an end of a large - diameter connecting tube component , and a smaller diameter ring - shaped portion 46 extending axially outwardly from the central portion of the larger diameter ring - shaped portion 44 . the smaller diameter ring - shaped portion 46 has an interiorly - threaded open end 46 &# 39 ; for receiving an end of a small - diameter connecting tube component , so that the small and large diameter connecting tubes may be interconnected . when the small and large diameter connecting tubes have outer diameters of 1 / 2 inches and 11 / 2 inches , respectively , the open interiorly - threaded ends of the small and large ring - shaped portions have outer dimensions of 3 / 4 of an inch and 13 / 4 inches , respectively . the last type of transition coupling elements is a &# 34 ; tube terminator ,&# 34 ; shown in fig6 a and 6b . the tube terminator 47 shown is simply a ring having an open interiorly - threaded female connecting end 47 &# 39 ; for closing off the end of the last connecting tube component in any series , to give a finished appearance . the other end of the terminator 47 is a truncated cone - shaped closed - off portion 47 &# 34 ;. the terminator preferably comes in two sizes to match the two diametric sizes of the connecting tube components 34 , as described above . it can , therefore , be seen that the large and small connecting tube components 30 may be arranged in a multitude of arrays and designs by utilizing the transition coupling elements . since each of the connecting tube components 30 and transition coupling elements is hollow , connections from the engineering modules , which simulate the interior working and living spaces of a space station or space ship , with the connecting tubes simulate the passageways or smaller working and living spaces of the space station or space ship . fig8 shows the assembly of two small - diameter tube components via a straight transition coupling element 32 , with an end of a tube being terminated with a terminator 47 . fig5 a and 5b show one of the fifth component series , which is a &# 34 ; command module .&# 34 ; each command module 48 is a hollow sphere or ellipsoid having at each end portion thereof a sleeve extension 48 &# 39 ;. each sleeve extension 48 &# 39 ;, which is similar to the sleeve 14 of the engineering module , has an interiorly - threaded open end for receiving therein an end of the small - diameter connecting tube component 30 . the command module 48 is also provided with a circumferential rib 49 for special effect . the command module is designed to simulate a command module of a space station or space ship , where the controls are situated . in any design or sculpture of a space ship or space station , only one such command module will usually be employed , though , of course , more than one may be used . the outer diameter of the sleeve extension 48 is preferably 3 / 4 of an inch , so as to receive therein an end of a small diameter connecting tube component 30 . fig9 shows one of the rail components 50 , which is simply an elongated bar member which is typically 3 inches in length . the bar may be either hollow or solid , and is so dimensioned that either end thereof will fit into a hole of the connecting tube components 30 and the engineering modules 10 . the rail components are meant to simulate lattice work structure of a space ship or space station extending from the connecting tubes and engineering modules . the sixth major component series are a plurality of rail coupling elements used to interconnect the rail components to provide a chain of such rail components . the rail coupling elements come in basically the same shapes as the transition coupling elements . the rail coupling elements are shown in fig1 a through 10e , and are , respectively , a straight connection 52 , a right - angle connection 54 , a 45 - degree angle connection 56 , an &# 34 ; x &# 34 ;- junction connection 58 , and a &# 34 ; y &# 34 ;- junction connection 60 . instead of the interiorly - threaded open ends of the transition coupling elements , the rail coupling elements simply have open ends in which the ends of the rail components are force - fitted . when the outer diameter of a rail component is 1 / 8 of an inch , the outer diameter of an open end of each rail coupling element is approximately 1 / 4 inch . in addition to the above described six major component series , there are also provided a number of supplementary component series for simulating other actual features of a space station or space ship . in fig1 a , one of a number of tank storage components 62 is shown which has a shape of a tank for storing fuel or oxygen and the like . the tank 62 has a plurality of holes 62 &# 39 ; in which are inserted an end of a tie stud or pin 64 shown in fig1 . each of the studs or pins 64 preferably has an enlarged knob 64 &# 39 ; at each end which pop into the holes provided on the engineering modules , the connecting tube components , and some of the supplementary components . thus , to attach a storage tank component 62 to an engineering module 10 or to a connecting tube connector 30 , the tie studs are inserted at their first ends in the holes 62 &# 39 ; of the tank storage component with their second ends being inserted in the holes of the engineering module or connecting tube component or another storage tank component , etc . it is emphasized that the holes of each of the engineering modules and connecting tube components come in at least a series of three , as described above , so that supplementary components , as the tank storage component , may be supported thereon by a number of tie pins . obviously , the spacing between the holes of the tank storage component is the same as the spacing between the holes of an engineering module and connecting tube component . these holes typically are 1 / 8 inch - diameter holes . tank storage component 62 may be ellipsoid - shaped or spherical , and the like . fig1 b shows another supplementary component , which is an antenna component 65 . the antenna component , as shown in fig1 b , is shaped as an antenna , and has a knob 65 &# 39 ; on the end of its support shaft to fit inside a hole on a connecting tube component 30 or an engineering module 10 . fig1 c shows still another supplementary component , which is a solar panel component , designed to look like a solar panel . the solar panel component 66 is provided with a series of holes 66 &# 39 ; around the circumference thereof , so that the tie studs or pins 64 may be inserted at first ends thereof , while their second ends are inserted into holes on the engineering modules or connecting tube components , or other components . the solar panel may be oriented either length - wise or width - wise depending upon which holes 66 &# 39 ; are used . fig1 a and 12b show supplementary components that are screwed onto small - diameter connecting tubes rather than being adjoined by the tie pins or studs 64 . in fig1 a , one of a number of landing pod components 70 is shown which is designed to look like a landing pod or foot of a space craft , as on the lunar lander . in this component , the main pod - shaped portion 70 &# 39 ; has an upstanding sleeve extension 70 &# 39 ; with interior threads for screwing on to an end of a connecting tube component of small diameter . typically , the outer diameter of the sleeve extension of the landing pod is 3 / 4 of an inch , so as to receive therein the small 1 / 2 inch connecting tube component . fig1 b shows one of the number of engine components designed to resemble a rocket engine . the engine component 72 has a funnel - shaped main body portion 72 &# 39 ; and a ring - shaped female mounting element 72 &# 34 ; having an interiorly - threaded open end remote from the funnel - shaped portion . the ring - shaped mounting element 72 &# 34 ; receives therein an end of a small diameter connecting tube component . fig1 shows one of the tether components 74 , typically 12 inches in length , which has knobs 74 &# 39 ; at its ends . the tether component 74 is a flexible element typically having 1 / 8 inch diameter end knobs 74 &# 39 ;. the tether 74 may also have an interior flexible wire to increase flexibility . each tether component knob fits into a hole formed in a portion of space man 76 shown in fig1 b , while the other end is force - fitted into a hole of one of the engineering modules 10 , or connecting tube components 30 , so as to simulate space walking . fig1 shows an air lock fitting component 80 which is designed to fit over an open or unused sleeve extension 14 of the engineering modules 10 , or sleeve extension 48 &# 39 ; at the command modules 48 , or sleeve extension 22 &# 39 ; of engineering module terminator 20 . each air lock fitting 80 has a screw - in portion 80 &# 39 ; of the same dimension as a small diameter connecting tube component 30 for screwing into the female connections end of a sleeve 14 . a flap 82 is also provided and is hinged to the screw - in portion 80 &# 39 ; by a tab 82 &# 39 ;. the flap 82 is for access to or closing off a sleeve 14 which simulates an air lock of a space ship or space station . fig1 a shows still another supplementary component , which is a heat radiator component 84 . the heat radiator component 84 is provided with a series of holes 84 &# 39 ; formed about its circumference for attachment by the tie studs or pins 64 , in the same manner as the solar panel component 66 . fig1 and 18 show examples of the different types of designs that may be produced with the knockdown toy of the present invention . fig1 shows a space ship design , while fig1 shows a space station design . in fig1 , it is clearly shown how the engineering modules 10 are connected together in a linear array , with each linear array being connectable to another linear array via connecting tube components 30 . since the design of fig1 is a space ship , a command module 48 is shown at the head of the design , connected to the central linear array of engineering modules 10 via connecting tube components 30 . storage tank components 62 are provided , as well as a modification of the storage tank components : the spherical storage tanks 63 mounted adjacent the engine components 72 at the rear of the two outer linear arrays of engineering modules . heat radiator component 84 is also shown attached to connecting tube components 30 between two linear arays of engineering modules . antenna component 65 is also shown attached to a connecting tube component 30 . further , there is shown a space walking space man 76 held to the space ship via tether component 74 , which is plugged into a hole of an engineering module 10 &# 39 ; at one end . though not shown in the drawing , each of the unattached sleeves 14 of the engineering modules and the sleeve 48 &# 39 ; of the command module 48 , and the sleeve 22 &# 39 ; of the engineering module terminators 20 , is closed of by an air lock fitting 80 . each of the supplementary components 62 , 63 , and 84 are attached to the space ship by tie studs 64 . in fig1 , a space station is shown . in this design , which approximates the design of nasa &# 39 ; s planned space station , there are 5 sets of engineering module linear arrays . in this design , the three arrays indicated by reference numerals 90 are attached to the array indicated by reference numeral 90 &# 39 ; via short versions of the small - diameter connecting tube components 30 indicated by reference numerals 91 . the figure also shows the use of the &# 34 ; x &# 34 ;- junction transition coupling element 38 and &# 34 ; x &# 34 ;- junction rail coupling element 58 . forty - five degree angle rail coupling element 56 is also shown connected to a pair of rail elements 50 . further , in the central linear array of engineering modules indicated by reference numeral 90 &# 39 ;, there may be provided a pair of connecting tube components 30 connected atop the engineering module terminators 20 , which connecting tube components are attached to the engineering module terminators by a screwing connection . while fig1 and 18 do not show all of the components parts described above , any of components described herein may be used in any arrangement designed by a user of the present invention . the end design or sculpture may simulate an actual space vehicle , as , for example , fig1 , which resembles the actual space station envisioned by nasa scientists , or it may simulate any fanciful design imagined . the designs of fig1 and 18 are shown only by way of example , and are not meant to show the only designs possible when using the parts of the present invention . clearly , an almost limitless number of different designs may be produced with the component parts of the present invention , with the only limiting factors being the imagination of the user and the number of component parts supplied . though particular dimensions have been set out in the above description of the various component parts of the present invention , it is to be understood that these have been stated only by way of example , and do not in any way limit the use of other - sized and other - dimensioned component parts . further , while the connections have been shown to be of the male - female type for the engineering modules 10 and connecting tube components 30 , as well as other components parts , it is to be understood that other equivalent mounting attachment or connections may be employed instead . further , while it has been shown that each engineering module 10 has identical construction , except for an end engineering module , it is part of the present invention to provide half of the engineering modules only with male attaching ends and half with female attaching ends . all of the parts of the present invention are preferably made of transparent plastic formed by injection molding or other equivalent processes , although other materials such as wood or cardboard can be used . further , while there have been shown five different coupling elements , it is to be understood that other differently - shaped and configured rail coupling and transition coupling elements may be utilized , such as octagonal and the like . the component series may also be color coded , so that each component series has a different color , or so components in each component series come in different colors . for example , the connecting tube components 30 may come in one color for the large - diameter tubes , another color for the small - diameter longer tubes , and still another color for the small - diameter shorter tubes . each component may further be identified by a decal fixable on the component , which decal has specially - written information thereon to describe the component and which may give any technical information thereon in order to simulate the kind of information carried by a real nasa component . each finished sculpture or design may be hung from a ceiling , and the like , for display . further , it is within the scope of the present invention to provide miniature furniture component pieces for insertion into the hollow components to simulate a real space station &# 39 ; s living conditions . a complete toy set made up of the component parts described above will typically have the following number of component parts : ______________________________________component part number______________________________________engineering modules ( 10 ) 20terminal engineering modules ( 24 ) 10engineering module terminators ( 20 ) 10connecting tube components ( 30 ) small diameter ( long ) 30small diameter ( short ) 10large diameter 10command modules ( 48 ) 5transition coupling elementsstraight ( 32 ) 20right - angle ( 34 ) 1045 - degree angle ( 36 ) 10 &# 34 ;
