The plurality of roller units 66 includes a pair of first roller units 68 and a pair of second roller units 70. Each of the first roller units 68 is positioned on the first portion 54 of the lid 50 and each of the second roller units 70 is positioned on the second portion 56 of the lid 50. Each of the roller units 66 comprises a bracket 72 which comprises a primary portion 74 that is perpendicularly oriented to a secondary portion 76. The primary portion 74 is coupled to the bottom surface 58 of the lid 50 having the secondary portion 76 extending downwardly from the bottom surface 58. Furthermore, the bracket 72 corresponding to each of the roller units 66 is positioned to extend along a respective one of a first lateral edge 78 and a second lateral edge 80 of the lid 50.

Each of the roller units 66 includes a plurality of rollers 82 that is each rotatably coupled to the secondary portion 76 of the bracket 72. The plurality of rollers 82 is spaced apart from each other and is distributed along a substantial length of the bracket 72. Each of the rollers 82 rests upon the lower section 46 of a respective one of the tracks 36 when the lid 50 is positioned in the closed position thereby facilitating the lid 50 to be rolled between the first position and the second position. A back edge 84 of the lid 50 is positioned adjacent to the back side 22 of the perimeter wall 18 of the box 12 when the lid 50 is in the first position. Conversely, the back edge 84 of the lid 50 is spaced from the back side 22 of the perimeter wall 18 when the lid 50 is in the second position.

A sliding unit 86 is integrated into the box 12 and the sliding unit 86 is in mechanical communication with the lid 50. The sliding unit 86 is actuatable in a closing condition for sliding the lid 50 into the first position. Conversely, the sliding unit 86 is actuatable in an opening condition for sliding the lid 50 into the second position. The sliding unit 86 comprises a screw 88 that has a first end 90, a second end 92 and an outer surface 94 extending between the first end 90 and the second end 92, and the outer surface 94 is threaded. As is most clearly shown in FIGS. 3, 4, 5 and 7, a plurality of gussets 96 may be disposed between the bottom wall 16 of the box 12 and a respective one of the back side 22 of the perimeter wall 18 and the support 32 for enhancing structural integrity of the box 12.

The sliding unit 86 includes a bearing 98 that is coupled to the back side 22 of the perimeter wall 18 of the box 12 having the bearing 98 being positioned inside of the box 12. The first end 90 of the screw 88 rotatably engages the bearing 98. The sliding unit 86 includes a motor 100 that is positioned on the support 32 which extends upwardly from the bottom wall 16 of the box 12. The second end 92 of the screw 88 is rotatably coupled to the motor 100 and the motor 100 is actuatable to rotate in a first direction or a second direction. The screw 88 is rotated in an opening direction when the motor 100 rotates in the first direction and the screw 88 rotates in a closing direction when the motor 100 rotates in the second direction. The motor 100 may comprise two direction electric motor 100 or the like. The sliding unit 86 includes a collar 102 through which the screw 88 extends such that the collar 102 threadably engages the outer surface 94 of the screw 88. The collar 102 is coupled to bottom surface 58 of the lid 50 and the collar 102 is positioned on the second portion 56 of the lid 50.

A jack 104 is pivotally disposed in the box 12 and the jack 104 pivotally engages the first portion 54 of the lid 50. The jack 104 is actuatable into a lowering condition for positioning the first portion 54 in the closed position and the jack 104 is actuatable into a lifting condition for positioning the first portion 54 in the open position. The jack 104 has a lower end 106 and an upper end 108, and the upper end 108 is extendable away from the lower end 106 when the jack 104 is actuated into the lifting condition. Furthermore, the upper end 108 is retractable toward the lower end 106 when the jack 104 is actuated into the lowering condition. The jack 104 may comprise an electrically actuated hydraulic jack, an electric linear actuator or any other type of lifting mechanism that can either lift or lower the lid 50.

A first pivot 110 is coupled to the top surface 60 of the bottom wall 16 of the box 12 and the first pivot 110 is positioned adjacent to the front side 20 of the perimeter wall 18 of the box 12. Furthermore, the lower end 106 of the jack 104 pivotally engages the first pivot 110. A second pivot 112 is coupled to the bottom surface 58 of the lid 50 and the second pivot 112 is positioned on the first portion 54 of the lid 50. The upper end 108 of the jack 104 pivotally engages the second pivot 112, and as is most clearly shown in FIG. 2, a clevis pin 114 may extend through the second pivot 112 to releasably attach the upper end 108 of the jack 104 to the second pivot 112. Each of the motor 100 and the jack 104 may be electrically coupled to a control panel that is conspicuously located to be easily accessible to a user for sliding the lid 50 as well as opening and closing the lid 50.

In use, the motor 100 is actuated to rotate in the first direction to slide the lid 50 into the second position. In this way the mattress 52 is more easily accessible for changing sheets on the mattress 52 or to rotate the mattress 52 on the lid 50. The motor 100 is actuated to rotate in the second direction to slide the lid 50 into the first position thereby positioning the mattress 52 for sleeping. Additionally, the jack 104 can be actuated into the lifting condition, regardless of the positioning of the lid 50, for opening the first portion 54 of the lid 50 to access the interior of the box 12. In this way objects that are stored in the box 12 can be accessed. The jack 104 can be actuated in the lowering condition to close the first portion 54 of the lid 50 at any time.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.

Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure.
