     DETAILED DESCRIPTION OF THE INVENTION 
     The mobile camping apparatus of this invention includes a vehicle in the form of a van 20. The van 20 has a body 22 and a roof 24. The roof 24 is angularly movable with respect to the body 22 by means discussed below. 
     Within the body 22 is a chamber 30 which is adapted to serve as living quarters, as illustrated in FIG. 3. 
     As shown in FIGS. 3, 11, and 15, carrier support structure 34 is supported by a mounting frame 36 at the upper portion of the van body 22. Mounted upon the carrier support structure 34 are spaced-apart U-shaped channels 40. A pin 46 is attached to each channel 40. A link 50 is attached to the pin 46. As shown in FIGS. 12, 13, and 14, each link 50 is attached to a bracket 54. Each bracket 54 is secured to an arm 60. The arm 60 has a rod 62 and knob 63 at one end thereof. The rod 62 and knob 63 are movable within a retainer bracket 64. The retainer bracket 64 is attached to a connector 65 which is attached to the roof 24. The other end of the arm 60 is pivotally attached by means of a pin 66 to another arm 70. The arm 70 is pivotally attached, intermediate the ends thereof, to the channel 40, by means of a pin 72, as shown in FIGS. 12, 13, and 14. The arm 70 also has an end pivotally attached to the connector 65 by means of a pin 74 adjacent an edge portion of the roof 24, as shown in FIGS. 12, 13, and 14. 
     Supported upon the carrier support structure 34 is a carrier unit 80, which is movable along the carrier support structure 34. Attached to the carrier units 80 and extending therebetween is a carriage 86. 
     Supported by the body 22 are pinion gear members 90 which are supported by a shaft 100 which is journalled in bearing blocks 99. A rotary motor 92 is operably joined to the shaft 100 for rotation thereof. The pinion gear members 90 are in mesh with elongate toothed racks 96 having teeth 98. The toothed racks 96 are attached to the carrier units 80. The shaft 100 extends from the rear portion of the body 22 to the front portion of the body 22. 
     Attached to the carriage 86 adjacent the support units 80 is a pair of spaced-apart pedestals 110. A pin 112 is attached to each pair of pedestals 110 and extends therebetween. 
     A channel-shape arm section 116 is pivotally attached to the pin 112. A channel-shape arm section 118 is pivotally attached to the arm section 116 intermediate the ends of the arm section 116. A pin 120 attaches the arm section 118 to the arm section 116. 
     An arm section 126 is pivotally attached to the arm section 118 by means of a pin 128 which is attached to the arm section 126. The arm section 118 has an elongate slot 130 therein, through which the pin 128 extends. A link 134 is rigidly secured to the arm section 126 and extends angularly therefrom. A pin 136 pivotally attaches the link 134 to a bracket 138 which is attached to the connector 65 which is secured to the roof 24 on the underside thereof. 
     The arm section 118 has an angular end surface 142. The arm section 126 has an angular end surface 144. 
     A flexible cover member 150 is attached to the roof 24 and is also attached to the carrier units 80. The flexible cover member 150 is provided with a window 154, as shown in FIGS. 2, 8, 9 and 10. Each of the carrier units 80 has attached thereto a horizontal abutment pin 160, which is adjacent the attachment of the flexible cover member 150 to the carrier units 80. 
     An elongate brace 166 is pivotally attached to each of the carrier units 80 by means of a bracket 168 and is also attached to the flexible cover member 150. 
     Between the two pairs of pedestals 110 the carriage 86 supports a bed structure 200. 
     FIGS. 3, 11, and 15 show that sets of arm sections 116, 118, and 126, and sets of arms 60 and 70 are at opposite portions of the apparatus. 
     OPERATION 
     FIG. 1 shows the mobile camping apparatus of this invention arranged for normal travel conditions. In the condition for travel, the bed structure 200 and the carriage 86 form a ceiling over the chamber or living quarters 30. 
     When the mobile camping apparatus is arranged for normal travel, as shown in FIG. 1, the roof 24 is in its down position upon the body 22, as illustrated in FIGS. 4, 12, 15, and 16. In this position, the carriage 86 and the bed structure 200 are positioned at the maximum positions thereof toward the right side of the body 22, as illustrated in FIGS. 4 and 5. In the positions shown in FIGS. 4 and 5, the horizontal abutment pin 160, which is attached to the carrier units 80, is positioned immediately above the end of the arm section 126. The arm sections 126, 118, and 116 are in horizontal alignment, as shown in FIG. 5. Due to the fact that the horizontal abutment pin 160 is immediately above the end of the arm section 126, as shown in FIGS. 4 and 5, the arm section 126 cannot move upwardly. Thus, the roof 24 is secured in its down position until the carriage 86 begins to move. 
     FIGS. 2 and 3 show the mobile camping apparatus of this invention in condition for camping use. When the mobile camping apparatus is arranged in the manner shown in FIG. 1 and it is desired to change to the conditions shown in FIGS. 2 and 3, the motor 92 is energized, and the motor 92 rotates the shaft 100, and the pinion gear members 90. The pinion gear members 90 are in mesh with the toothed racks 96. The toothed racks 96 are attached to the carrier units 80. Therefore, rotation of the pinion gear members 90 causes linear movement of the carrier units 80. As the motor 92 initially rotates the pinion gear members 90, the carrier units 80 and the carriage 86 move slightly to the left, as shown in FIG. 6. Thus, the horizontal abutment pins 160 are moved slightly to the left, as illustrated in FIG. 6. Thus, movement of the carrier units 80 and the pins 160 to the left, releases the arm sections 126 for upward movement, and thus the roof 24 is movable upwardly. 
     As the motor 92 continues to operate and the pinion gear members 90 continue to rotate and the toothed racks 96 continue to linearly move, the carrier units 80 are linearly moved toward the left of the body 22, as shown in FIGS. 7, 8, 9, and 10. Thus, the arm sections 126, 118, and 116 are moved toward the left. 
     Due to the fact that each arm section 126 is attached to the roof 24, movement of the arm sections 116, 118, and 126 toward the left forces the roof 24 to begin to pivotally move upwardly, as illustrated in FIG. 7. 
     As the arm sections 126, 118, and 116 move toward the left with movement of the carrier units 80, each arm section 126 is pivotally moved upwardly with pivotal upward movement of the roof 24. The arm sections 126 continue to pivotally move with respect to the arm sections 118 until the angular end surface 144 of each arm section 126 engages the horizontal surface of its respective arm section 118, as illustrated in FIG. 7. 
     Then further movement of the carrier units 80 to the left forces the roof 24 farther upwardly, and the arm sections 118 pivotally move with respect to the arm sections 116, as illustrated in FIG. 8. As the carrier units 80 and the arm sections 118 and 116 continue to move to the left, the arm sections 118 continue to pivotally move with respect to the arm sections 116 until the angular end surface 142 of the arm sections 118 engages the horizontal surface of the arm sections 116, as illustrated in FIG. 8. 
     Then continued travel of the carrier units 80 to the left forces the arm sections 116 to pivotally move with respect to the carrier units 80, and the roof 24 is pivotally moved upwardly to a greater degree, as illustrated in FIG. 9. As the carrier units 80 continue to travel to the left, the arm sections 116 pivotally move with respect to the arm sections 118 until the arm sections 116 are in axial alignment with the arm sections 118, as illustrated in FIG. 10. Thus, the roof 24 is pivotally moved to its maximum degree. 
     As the roof 24 is moved upwardly with movement of the carrier units 80 to the left, the carriage 86 and the bed structure 200 are moved to the left and extend from the side of the body 22, as best illustrated in FIGS. 2 and 3. 
     As the roof 24 is pivotally moved in the manner discussed above, and as the carrier units 80 move to the left, the brace members 166 are moved to the left by the carrier units 80 and pivotally move upwardly and force portions of the flexible cover member 150 upwardly, as illustrated in FIGS. 9 and 10. Thus, the flexible cover member 150 is forced to extend outwardly between the roof 24 and the carriage 86, as illustrated in FIG. 10. 
     As the carrier units 80 and the carriage 86 are moved to the left and as the roof 24 pivotally moves upwardly, the links 50, the arms 60, and the arms 70 are pivotally moved upwardly, as illustrated in FIGS. 13 and 14. As the roof 24 angularly moves and as the arm 60 pivotally moves, the rod 62 and knob 63 move transversely within the retainer bracket 64. Pivotal movement of the arms 60 and 70 forces the right hand edge of the roof 24 to move upwardly and to the left, as illustrated in FIG. 13. As the roof 24 is moved to its maximum upper position, as shown in FIG. 14, the right hand edge of the roof 24 is moved into engagement with the upper right hand portion of the body 22, as shown in FIG. 14. Thus, the roof 24 seals against the body 22 in the maximum upper position of the roof 24. 
     The hinge mechanisms comprising the arms 60 and 70 and the link 50 provide means by which the apparatus of this invention is adapted for use with vans of various sizes and shapes and dimensions, due to the fact that the edge of the roof 24 rises and re-seats as the roof 24 angularly moves. 
     Thus, when the carriage 86 and the bed structure 200 are positioned as illustrated in FIGS. 2 and 3, the chamber 30 has head room in which a person may stand in the region to the right of the bed structure 200, as shown in FIG. 3. 
     FIG. 17 
     FIG. 17 shows a van 300 having a roof 304. This view shows another embodiment of this invention In this embodiment the apparatus is positioned ninety degrees with respect to the apparatus shown in the other figures. The van has a roof 304. In the embodiment shown in FIG. 17, the carrier units 80 and the carriage 86 and bed structure 200 move toward the front of the van 300 as the roof 304 is pivoted about the rear part of the van 300. Thus, the front part of the roof 304 is moved upwardly with pivotal movement by the roof. Substantially the same operation of elements occurs in this embodiment as occurs in the embodiment of the other figures. 
     Although the preferred embodiments of the mobile camping apparatus of this invention have been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts, the combination thereof, and the mode of operation, which generally stated consist in a apparatus within the scope of the appended claims.
