Referring now particularly to FIGS. 17 and 19, 50 represents a foundation floor that has a step up terrace 51 with appropriate foliage 52 in the corners thereof, a breezeway 53 with foliage 54 and a garage floor 55 ex tending therefrom. Other appropriate foliage can be located over the concrete floor and the usual landscaping 52' may be provided. A concrete Walk 56 running parallel with the garage area 55 extends rearwardly from the foundation floor area. Upon the main part of the floor area 50, there is erected an exterior building shell 57 hav ing a windowed front wall 58, a less windowed rear Wall 59 with a door 60 aligned with the concrete walk 56 and unwindowed side end walls 61 and 62. These exterior walls are made up of any standard construction and may be prefabricated and assembled. Running along the upper 3 portions of and incorporated in the front and rear walls are attaching hanger plates 63 and 64, FIGS. 18 and 19.

A combined roof and ceiling structure 65 is supported upon the walls and has a central I-beam 67 that runs from one end wall to the other. The hanger plates'63 and 64 respectively support single trolley track troughs 68 and 69. The I-beam 67 supports a double trolley track trough 71. These trolley track troughs may be made from light weight extruded aluminum. The single trolley track troughs 68 and 69 respectively have a vertical portion 72 by which they are secured to hanger plates 63 and 64 by bolts 73 and a horizontally extending portion 74 having a track groove 75 running therealong, FIG. 8. Running along the trough 68 between the vertical and horizontal portions is an undercut recess 76 that provides a reflecting surface for light rays projected from fluorescent tubes 77 that are mounted in the recess and run the full length of the trolley trough to indirectly light the rooms.

The double trolley track trough 71 has a vertical central portion 77 and two horizontally-extending track portions 78 and 79. Between these vertical and respective horizontal portions are respective undercut recesses 80 and 81 that provides reflecting surfaces and house respectively fluorescent lighting tubes 82 and 83 that run the full length thereof. The horizontally-extending portions 78 and 79 respectively have track grooves 84 and 85. The vertical portion 77 is attached to the bottom of the I-beam 67 by bolts 86 and 87, FIG. 9. These bolts are connected to a hard metal plate 88 embedded in the top of the vertically-extending portion 79 and the portion 29 is anchored thereto by long vertical bolts 89. A finished interior floor outline 91 may be provided having equal-sided squares 92 that may measure any desired dimension on each side FIG. 2. A rectangular area 93 supports a prefabricated combined kitchen and bath unit 94 with a kitchen space K and bathroom spaces B. Appropriate piping is provided to supply the necessary water to the kitchen sinks, lavatories and water closets. This combined unit may have appliances and closets provided in the rooms. A fireplace or open grill 95 is also provided on the area 93 on the exterior of the unit 94. This combined unit 94 in this layout is spaced from the rear wall 59 to provide a runway 96 along the rear of the house for access to and from back door opening 60 and between the opposite side ends of the house.

Along the floor squares 92 there are provided several series of self-closing bottom latch socket devices 97, FIGS. 10 and 11. These socket devices are secured by screws 98 to the floor 91. Each device has a closure plate 99 which is normally held in the closed position with its lower stop plate 100 against shoulder 101 by a compression spring 102 lying in the bottom of the socket. There are two of these sockets along joined edges of the squares 92. These socket devices are adapted to receive plug latch elements of the wall sections that will be later described. a

It will be apparent that parallel trolley track troughs oppose one another at each side of the longitudinally-extending I-beam 67. Shiftable wall assemblies 105 formed of prefabricated wall sections or panels 106 and the trolley bar or beams 107 or 108 can be moved to any spaced distance between the ends of the building. The trolley bars 107 and 108 have their ends recessed to receive the respective horizontally-extending portions of the trolley troughs. The trolley bars 107 and 108 respectively have rollers on their ends that travel in the track grooves 75, 84 and 85.

The trolley bars have an opening 111 on their opposite ends that contain a spring latch linkage 112. This linkage has a latch plug 113 adapted to enter any one of latch openings 114 in the trolley troughs spaced from one another at distances equal to the distances between the floor squares 92. The latch plug 113 is urged toward the plug socket receptacle 114 by a compression spring 115 and can be released from the plug opening by pulling downwardly on an easily accessible hand knob 116 that extends outwardly through a slot 117 in a side cover plate 118. The spring reacts against a shelf plate 119. The plug socket receptacle 114 has a bottom 120 through which a switch actuator 121 extends. This actuator has an internal plate 122 within the receptacle 114 that is engaged by the plug 113 and depressed against the action of a compression spring 123 to open a switch 124 connected in circuit relation through appropriate wiring 125 connected with an electric source and with fluorescent tubes 77, 82 or 83, FIG. 5.

Each Wall section 106 has an internal frame 127 and a top tongue projection 128, FIG. 17. Cover pieces 129 and 130 overlie the frame 127 and disposed therebetween is sound deadening material 131. Within the tongue projection 128 and adjacent the respective ends thereof, are respective latch notches 132 and 133, and in the notches 132 and 133 are a pair of opposing swing latch plates 134 and 135 that are respectively connected to pinions 136 and 137 journalled in the tongue notches 132 and 133, FIG. 6. These latch plates are operated by a doublesided rack gear 138 and pinions 136 and 137 in mesh therewith. The gear rack 138 is pulled down from the notch and into an opening 138 in the wall section 136 by a pull rod 139 against the action of a compression spring 140 that is shouldered at 141 within the opening 138. The rod 139 is operated by a hand lever 142. Each of the trough bars 107 and 108 has a groove 143 running along its under edge that has opposing shoulders 144 and 145 adapted to be engaged by the respective swing latch plates 134 and 135, FIG. 6. When the hand lever knob 142 is operated the latch plates 134 and 135 are retracted and the tongue projection 128 of the wall section 106 may be then inserted into the groove 143. Upon the hand lever 142 being released, the spring 140 will lift the rack 138 and position the latch plates 134 and 135 to engage the respective shoulders 144 and 145. This assemblage provides releasable devices upon the tongue projections to suspend the wall sections 106. The width of these wall sections 106 are equal to the dimension of the imaginary squares 92 and several of the wall sections are suspended from the trolley bar 107 or 108 to make up the full wall section assembly 105. The wall assemblies 105 can be made up of four or five sections and can be pushed or shifted from one side end of the building to the other. When the assemblies are not needed to make the rooms they are stored in the side ends of the building upon the trolley track troughs. With all of the wall assemblies 105 in one end or the other of the building a full floor space isprovided for open living. To provide the different rooms, the wall assemblies 105 are moved from the side end walls and fixed within the building at any one of several spaced locations along the trolley troughs.

Within the bottom of each wall section at each side thereof is a bottom latch linkage 146 having a latch plug 147 adapted to enter any one of the floor receptacles 97 with which the wall assembly 105 will be aligned, FIG. 9. A compression spring 148 reacts upon the linkage 146 to normally urge the plug downwardly and into the recep tacle 97. To lift the plug latch 147, a hand lever 148 is depressed against the action of a compression spring 149. By the plug latches 114 of the trolley bar 107 or 108 and the floor plug latches 147, the Wall assembly is held immovable against longitudinal displacement along the trolley troughs and through the building. To move the wall assemblies 105 the pull knobs 116 of the trolley bar 107 or 108 and the floor hand levers 148 of the wall sections are simultaneously operated thereby allowing the assembly to be moved to and from the end storage space or shifted to an adjusted position.

The Wall assemblies 105 can be shifted in the building to different distances to provide any one of the room layouts shown in FIG. 1. In order to close the inner ends of the rooms, individual wall sections 106 shown in FIG. 2 stored in one side end of the building are taken one at a time and placed in groove 151 in the central double trolley trough. To do this, the latch plates 134 and 135 are retracted and the tongue projection 128 is slid upwardly into a groove 151 and released within the groove 151 to engage shoulders and 153 thereof. The number of these wall assemblies that are used depends upon the length of the exterior building structure. These wall assemblies are light in weight and can be easily lifted and handled. The dimensions of the wall sections, the length of their tongue projections 128, the width and shape of the slot in the trolley bar and the height of the sections are such that they can be lifted broad side and assembled in the trolley bar slots to be suspended from the trolley bars and closed with the floor at their bottom edges by pile fabric depending from the surfaces of these edges. All of the knobs 116, and levers 142 and 148 are preferably made so that they may be locked in their plug retracted positions and the hands left free to move the wall assembly along the trolley track.

In order to have a door in the wall assembly 105 a wall section 155 is used, FIG. 12. This wall section has a door opening 156 in which a door 157 is hinged. This section 155 has a tongue projection 158 on its upper edge adapted to be fitted into either the groove 143 of the trough bars or groove 151 of the double trolley track trough 71. This tongue projection 158 has notches 159 and 160 from which latching devices 161 and 162, the same as those above described for the plain wall sections, are extended and released by respective hand levers 163 and 164. Bottom plug latch devices 165 and 166 respectively have hand levers 167 and 168 located respectively adjacent to the upper latch hand levers 163 and 164. These hand levers are also adapted to be locked in their retracted positions. This door wall section 155 can be either lifted separately and placed on the double trolley track trough or can be made a part of a wall assembly 105 and supported on the trolley bar 107 or 108.

In FIGS. 21 and 2.2, there is shown a closet or cabinet 171 that may stand substantially the full height of the wall. This closet has a floor bottom 175. Slide doors 173 and 174 are supported on a bottom frame 176 that is in turn supported and carried on a dolly 177 having caster wheels 178. Above the large compartment 172 is small compartment 179 that has a shelf support 180, twin doors 181 and 182 and a top frame 183. The closet is mounted on a wall section 185 of the same width and height of the wall sections 106 and 155 that has bottom plug latches 186 adapted to enter the floor receptacles 97 and lifted by a pivot lever 187 against the action of the spring 188. In the upper part of the wall section 185 is a retractable latch 189 adapted to fit the groove 143 of the trolley bar and groove 151 of the double trolley trough 71 and urged toward its latching position by compression springs 190. This latch 189 is retracted against the action of the springs 190 by pull knobs 191 that may be locked to the latch in its retracted position. It will be seen that these closets 171 can thus be located in any one of the wall assemblies and be accessible from a room space. These closets 171 when free of the walls can be stored at the side ends along with individual wall sections 106 and 155.

To close the cracks between the wall sections and to improve the appearance of the wall assembly surface, the sides of the faces of the wall sections 106 are provided with three spring sockets 193 and 196 into which plugs 194 of closure strips 195 can be fitted. These closure strips 195 extend the full height of the wall sections and will completely cover the cracks between the wall sections. The door wall section 155 has similar socket openings 196 that receive the plugs 194 of the cover strips 195.

To provide finish on the side edges of the wall sections spaced pairs of socket openings 199 are used to receive the plugs 194 to fix the cover strip 197 thereover, FIGS. 17 and 18. Similar socket openings 200 are provided in the edges of the door wall section 155 so that the cover strip 195 can be attached thereto. All of these socket openings have opposing inwardly bent fiat springs 201 adapted to be joined with indentations 202 on the opposite sides of each plug 194, FIG. 18.

Where the wall sections 106 or are joined to form a corner as illustrated in FIG. 20, an angle strip 197 is fitted inside the corner so that plugs 198 thereof enter socket openings 193 or 196 of the joined Wall sections 106. The exterior of the corner, FIG. 20, has a corner filler piece 203 of square section that is held in place by cover strips with its plugs 194 entering the wall section socket openings 199.

The closets 171 are provided with sockets 204 on their front faces. They can be joined with one another by closure strips 195. The socket openings permit the closets 171 to be joined by angle plates 197 with wall sections 106 and 155.

While different wall sections including a door and a closet unit have been provided, it will be understood that other types of wall sections in the nature of book cases, chests, store-away beds, etc. can be similarly provided. The furniture used in this type of a house would include studio couches that can be converted into beds for use in the bedrooms.

The fluorescent tubes 77, 82 and 83 are disposed along the trolley track troughs 68, 69 and 71, and are individually controlled by respective switches 207. They are supported with current from a main supply line 208 that has a main switch 209. As the wall assemblies 105 are positioned and the top plug latches 113 are connected to the switch receptacle 114 to open switches 124 the fluorescent tubes are automatically sectionalized so as to be controlled by the individual switches 207. The fluorescent lights 82 and 83 on the respective sides of the double trolley are joined in parallel circuit relationship with the respective fluorescent tubes lying within the respective single trolley troughs 68 and 69, are controlled therewith.

To prevent light and air from passing between the upper edge of the trolley bar 108 and the ceiling surface 65, a pile fabric strip 211 is fixed to the upper edge of the trolley bar so as to be moved therewith, FIG. 4. In the trolley troughs, there is fixed thereto at intervals equal to the length of the fluorescent tubes, closure members 210 to block off light that would pass through the trolley trough to an adjacent room. The pile fabric 211 will extend over the rounded ends of the bar and engage with the inner edges of the closure members 210. On the bottom edges of the wall sections are similar pile fabric strips which are secured thereto so that the hairs thereof engage with the floor surface and thereby prevent the passage of light through the walls at the floor.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.
