Description:
BACKGROUND OF THE INVENTION 
     Numerous types of mobile camping equipment have been created in which sleeping accommodations are available. Known mobile camping equipment presents various problems which the apparatus herein disclosed is constructed to solve. 
     One of the major problems involved in known mobile camping equipment in which a van type automotive vehicle is involved is that when the sleeping accommodations are positioned for the normal use, the living quarters in the van are severely restricted. 
     It is an object of this invention to provide mobile camping apparatus in which an automotive van or the like includes bed structure which is operable to a substantially lateral position with respect to the van, so that substantially all of the space within the van is available for use and in which additional &#34;head room&#34; is provided within the van when the bed structure is in its position for use. Thus, when the bed structure is positioned for usage, the entire normal space within the van plus additional head room is provided. 
     Another object of this invention is to provide such mobile camping apparatus in which the van is arranged for normal usage when the bed structure is not positioned for usage.

     DETAILED DESCRIPTION OF THE INVENTION 
     The mobile camping apparatus of this invention includes a vehicle in the form of a van 14. The van 14 has a body 18 and a roof 20. The roof 20 is hingedly attached to the body 18 by means of one or more hinges 24, shown in FIGS. 4, 5, 7, 8, and 9. Within the body 18 is a chamber 30 which is adapted to serve as living quarters. Within the body 18, adjacent the upper portion thereof and extending along the left hand side of the chamber 30, is a support member 34, shown in FIG. 4. Within the body 18, adjacent the upper portion thereof and extending along the right hand side of the chamber 30 is a channel member 35, shown in FIGS. 3 and 6. Mounted upon the body 18, adjacent the upper portion thereof and extending along the right hand side of the chamber 30, within the channel member 35, is a connecting shaft 36. The connecting shaft 36 is rotatably journaled in bearing housings 38 which are attached to the channel member 35, intermediate the ends of the connecting shaft 36. At the rearward portion of the body 18, the connecting shaft 36 extends through a gear box 40. At the foward end portion of the body 18 the connecting shaft 36 extends into a gear box 42. 
     Adjacent the rearward portion of the body 18 is a motor 46, which is preferably an electrically operable motor, which is energized through electrical conductors, not shown, connected to a source of electrical energy, not shown. A drive pulley 48 is attached to the connecting shaft 36 adjacent the gear box 40. The motor 46 has a drive pulley 50 attached thereto for rotation therewith. A drive belt 52 encompasses the drive pulleys 48 and 50. 
     Extending transversely across the body 18 at the upper forward portion thereof and attached thereto is a U-shape rail member 58, which has one end portion adjacent the gear box 42. Attached to the U-shape rail member 58 and extending therefrom parallel thereto and along the length thereof is an L-shape channel member 59, best shown in FIG. 6. Extending transversely across the body 18 and attached thereto at the upper rearward portion thereof is a U-shape rail member 60, which has an end portion adjacent the gear box 40. Attached to the U-shape rail member 60 and extending therefrom parallel thereto is an L-shape channel member 61. 
     Extending along the U-shape rail member 58, adjacent and parallel thereto, is an L-shape frame member 64, shown in FIG. 6. Extending along the U-shape rail member 60, adjacent and parallel thereto, is a frame member 66. 
     A plurality of wheel members 68 are rotatably attached to each of the frame members 64 and 66, and are positioned within the U-shape rail members 58 and 60 and roll therewithin and support the frame members 64 and 66. The U-shape rail members 58 and 60 are oriented so that the legs thereof are horizontal, and the wheel members 68 are positioned between the upper and lower legs of the U-shape rail members 58 and 60. 
     As shown in FIG. 5, attached to the frame members 64 and 66 and extending therebetween are frame members 70 and 72. Spaced from the frame member 64 and parallel thereto and attached to the frame members 70 and 72 is an intermediate support member 76. Spaced from the frame member 66 and parallel thereto and attached to the frame members 70 and 72 is an intermediate support member 78, shown in FIG. 5. The intermediate support members 76 and 78 and the frame members 70 and 72 support a bed member 80. 
     Attached to the frame members 64 and 66 are arm members 84, each of which has an end portion pivotal about an attachment member 86. The other end of each of the arm members 84 is pivotally attached to a connector member 90. Each connector member 90 is rigidly attached to a lever member 94. The lever member 94 has a roller 96 intermediate the ends thereof and a roller 98 adjacent one end thereof. The other end of the lever member 94 is pivotally attached to a bracket 99 which is secured to the roof 20 on the lower surface thereof. The bracket 99 has an abutment portion 101. 
     Extending from the gear box 40 and along the U-shape rail member 60 is a threaded rod 100. Extending from the gear box 42 and along the U-shape rail member 58 is a threaded rod 102, best shown in FIG. 6. 
     The gear boxes 40 and 42 are of the type provided with gear members therewithin, not shown. The gear members within the gear boxes 40 and 42 join the connecting shaft 36 to the threaded rods 100 and 102. The gear members within the gear boxes 40 and 42 are such that the rate of rotation of the threaded rods 100 and 102 is significantly less than the rate of rotation of the connecting shaft 36. 
     As best shown in FIGS. 5 and 6, the L-shape frame member 64 has nuts 126 attached thereto, and the L-shape frame member 66 has nuts 128 attached thereto. The threaded rod 102 threadedly extends through the nuts 126. The threaded rod 100 extends through the nuts 128. 
     The threaded rods 100 and 102 are rotatably journaled in bearings 106 at one end thereof. The other end of the threaded rod 100 is connected to the gear box 40, and the other end of the threaded rod 102 is connected to the gear box 42. 
     Attached to each nut 126 is an actuator member 131 which is engageable with limit switches 140 and 142 for operation thereof. 
     Attached to the roof 20 and to the frame member 70 and extending the length of the frame member 70 is a flexible wall member 110, which may be of canvas or any other suitable tent-like material. The flexible wall member 110 also is attached to sealing strips 114 which are attached to the top portion of the body 18 and extend thereacross adjacent the L-shape channel members 59 and 61. 
     Pivotally attached to the L-shape support members 64 and 66, by means of brackets 146, is a U-shape brace member 150. The brace member 150 has a central portion which extends between the frame members 64 and 66 and which is attached to the flexible wall member 110 by means of tie members 155. 
     OPERATION 
     FIG. 1 shows the mobile camping equipment of this invention arranged for normal travel and use conditions. In the condition for normal travel the bed structure which includes the bed member 80 forms a ceiling over the chamber or living quarters 30. FIGS. 2 and 3 show the mobile camping equipment of this invention in condition for camping use. 
     When the mobile camping equipment 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 46 is energized and rotates the drive belt 52. The drive belt 52 rotates the drive pulley 48 and the connecting shaft 36. The connecting shaft 36, through the gear boxes 40 and 42 drives threaded rods 100 and 102. The gears within the boxes 40 and 42 are such that the threaded rods 100 and 102 rotate at a much lower rate than the rate of rotation of the connecting shaft 36. Due to the fact that the threaded rods 100 and 102 are journaled in bearings 106, the threaded rods 100 and 102 do not have axial movement. Therefore, as the threaded rods 100 and 102 rotate, the nuts 126 and 128 travel along the threaded rods 100 and 102, from the right side of the body 18 toward the left side of the body 18. Travel of the nuts 126 and 128 causes travel of the frame members 64 and 66. As stated and as shown, the frame members 64 and 66 are supported by the wheel members 68 which roll between the horizontal legs of the U-shape rail members 58 and 60, respectively. Thus, as the frame members 64 and 66 are moved, the wheel members 68 rotate and travel upon and within the U-shape rail members 58 and 60 and support the frame members 64 and 66 in the travel thereof. The intermediate support members 76 and 78 and the bed member 80 travel with the frame members 64 and 66, as illustrated by arrows 170 in FIGS. 5 and 8. Thus, the bed structure, including the bed member 80, is moved laterally with respect to the body 18, as the frame members 64 and 66 are supported by the wheel members 68 which roll upon and within the rail members 58 and 60. 
     As the frame members 64 and 66 travel in a right to left direction with respect to the body 18, the frame members 64 and 66 move the arms 84 in a right to left direction. As shown in FIGS. 4 and 7, the arms 84 and the lever 94 are substantially horizontal when the bed member 80 is in its maximum right position, serving as a ceiling over the chamber 30. The roller 96 of each of the levers 94 rests upon the L-shape frame members 64 and 66. As the frame members 64 and 66 travel from right to left as illustrated by arrows 170, the arms 84 exert a force upon the connector members 90, and the lever members 94 travel a short distance along the upper surface of the frame members 64 and 66, as the rollers 96 which are attached to the lever members 94 roll upon the frame members 64 and 66. 
     Due to the fact that the lever members 94 are attached to the roof 20 by means of the brackets 99, the lever members 94 apply a force upon the roof 20, as the arms 84 travel from right to left. Thus, the roof 20 is urged upwardly and begins to pivotally move upwardly about the hinges 24, as illustrated in FIGS. 4 and 7. As the frame members 64 and 66 continue to move the arms 84 in right to left travel, continued pressure is applied to the lever members 94, through the connector members 90. Therefore, the lever members 94 pivotally move upwardly as lever members 94 move the roof 20 upwardly, as illustrated in FIGS. 4 and 8. The lever members 94 pivotally move, and the roof 20 pivotally moves, as illustrated by arrows 178, until the lever members 94 assume substantial right angles with respect to the frame members 64 and 66, and the lower ends of the lever members 94 engage the arms 84. 
     As the frame members 64 and 66 force the arms 84 farther in a right to left direction, the arms 84 pivotally move as lever members 94 continue to urge the roof 20 to pivotally move upwardly, as illustrated in FIGS. 4 and 9, as illustrated by arrows 180. The arms 84 and the lever members 94 continue to pivotally move the roof 20 upwardly until the roof reaches the position shown FIGS. 4 and 9. In this position, each of the lever members 94 engages the abutment portion 101 which is a part of each bracket 99. Thus, the roof 20 is firmly retained in the position thereof shown in FIGS. 4 and 9 by the threaded rods 100 and 102, by the arms 84 and by the lever members 94. At this position a substantial part of the frame members 64 and 66 is positioned laterally in cantilever fashion with respect to the body 18, as illustrated in FIG. 4. Thus, a substantial portion of the bed 80 is at a lateral position with respect to the body 18. Due to the fact that the wheel members 68 travel upon the U-shape rail members 58 and 60, between the horizontal upper and lower horizontal legs thereof, at least some of the wheel members 68 may engage the upper legs of the U-shape rail members 58 and 60 when the frame members 64 and 66 extend outwardly in cantilever fashion from the rail members 58 and 60. 
     The actuator member 131 engages the limit switch 142 to deenergize the electric motor 46 when the roof 20 has moved to its maximum upward position. 
     As the roof 20 pivotally moves upwardly and as the frame member 70 moves outwardly from the body 18, the flexible wall member 110 is unfolded and stretched between the roof 20 and the frame member 70 at the left side of the body 18. Also as the flexible wall member 110 is stretched, the U-shape brace member 150 is pivotally moved, as illustrated in FIG. 4 and retains the flexible wall member 110 in a taut condition between the roof 20 and frame member 70. 
     As the roof 20 pivotally rises and as the flexible wall member 110 is stretched, the portions of the flexible wall member 110 at the forward and rearward ends of the body 18 are stretched into position between the sealing strips 114 and the roof 20, as illustrated in FIGS. 2 and 3. FIG. 2 shows that an end portion of the flexible wall member 110 may have a window 200 therein for ventilation. 
     Thus, the mobile camping equipment is arranged for sleeping therein. As shown in FIG. 3, the chamber or living space 30 within the body 18 has greater availability for use. The bed structure has moved from a ceiling position above the living space 30 and the head room available within the living space 30 is greater when the bed member 80 is positioned as shown in FIG. 3. Thus, the mobile camping equipment of this invention provides sleeping quarters when the bed member 80 is positioned as shown in FIG. 3, and when the bed member 80 is positioned as shown in FIG. 3 increased living quarters 30 are provided within the body 18. 
     When it is desired to retract the roof 20 and the bed member 80, the electric motor 46 is energized to rotate in a reverse direction, and the members discussed above move in a direction to retract the frame members 64 and 66, to move the bed member 80 to the position thereof shown in FIG. 7, and to lower the roof 20 to the position thereof shown in FIG. 1. 
     Although the preferred embodiment of the mobile camping apparatus of this invention has 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 structure within the scope of the appended claims.
