[ 0057 ] fig3 is an enlarged , partially - exploded cross - sectional view of the module 10 l and left truck side 62 . the lower right rabbet 102 provides a channel for receiving a series of rollers 104 ( which are disposed one behind another from the view of fig3 ). the rollers 104 are fixed to the wall 30 at their axes to allow free rotation . receiving a like series of rollers 104 fixed to wall 28 is the rabbet 102 formed in the wall 30 ( not depicted ). the rollers 104 are supporting the drawer 100 for longitudinal motion in the housing 14 . a stop 69 operating by a screw action is anchored within wall 30 . rotating the stop 69 extends it into the rail 112 . the stop 69 does not interfere with the motion of the drawer longitudinally when the stop is in a first position away from contact with the drawer 100 . a second position for arresting motion of the drawer by frictional force results from rotating the stop 69 until it makes contact with the drawer 100 . multiple forms of construction and modes of operation for the stop 69 are well known to those having skill in the art , and lie within the scope of the present invention . the particular embodiment of the stop 69 described is exemplary and is not intended to be limiting . a weather strip 70 provides a seal between the truck side rail 68 and the top of the side flange 66 . the top of the truck bed wheel well 72 retains a nut zert device 74 that receives the mounting bolt 40 . tightening the bolt 40 in the nut zert 74 secures the outer extent of the upper surface 22 to the wheel well 72 ( not shown in fig3 but shown in fig1 b ). a like nut zert 74 in the truck bed 12 receives the bolt 44 . tightening the bolt 44 in the nut zert 74 secures the mounting plate 48 , and thus the housing bottom 42 , to the truck bed 12 . nut and bolt assembly 200 is illustrated in fig2 and 3 but omits various components for clarity . a detailed view of assembly 200 is provided in fig8 a , 8b and 8 c . [ 0060 ] fig4 is an exploded view of the construction and interrelation of the parts of the nut zert device 74 , the mounting plate 48 , and the housing bottom 42 relative to the truck bed 12 . the bolt 44 passes successively through a washer 76 , the aperture 46 in the mounting plate 48 , and an opening 78 in the housing bottom 42 . the nut zert device 74 is receiving the bolt 44 . the nut zert device 74 is disposed within an opening 80 in the truck bed 12 and includes a threaded channel 82 for screwing the bolt into . the nut zert 74 is held in the opening 80 by a washer 84 and nut 86 . a plurality of pads 92 are affixed to the lower outer surface of the bottom 42 for easing the placement of the module 10 into the truck bed 12 as seen clearly in fig4 . it should be understood that the pads 92 are only one way of lessening friction to facilitate installation and removal of the present invention . the present invention includes numerous other ways of lessening friction that are well known to those of skill in the art . thus , the particular embodiment of the pads 92 described is exemplary and is not intended to be limiting . [ 0061 ] fig5 is a side view of the housing 14 , partially extended drawer 100 , and side flange 66 of the module 10 according to the first embodiment of the present invention . a plurality of holes 88 are arrayed along the upper portion of the side flange 66 . the nut and bolt assemblies 200 comprising asymmetrical nut 202 , bolt 204 , and biasing bolt 205 passing through the holes 88 secure the side flange 66 to the truck side . a plurality of perforations 90 are arrayed along the lower portion of the side flange 66 . the bolts 64 passing through the perforations 90 secure the side flange 66 to the housing top 22 . as can be seen from the drawing , fig5 is a view of the side of the truck with the wall 28 closer to the viewer . the optional ports 94 , 96 ( depicted as circular but may also be differing shapes ) in the wall 28 provide access for various purposes through the wall 28 . the optional ports 94 , 96 are each disposed in the general vicinity of the ends 98 of the housing 14 . the optional ports 96 are positioned in the wall 30 at similar relative locations to the optional port 94 in the wall 28 . the optional ports 96 exist to permit user access to the bolt 44 through the wall 30 . thus , when a user reaches through the optional port 96 , the user can tighten the bolt 44 . the housing end 98 closest to the front end of the truck is secured to the truck bed 12 by tightening of the bolt 44 . when installing two modules 10 l and 10 r , respectively , to span the truck bed , one module , for example module 10 l , is installed first followed by installation of a second module 10 r . [ 0063 ] fig6 a and 6b show longitudinal and side views , respectively , of optional variations in the construction of the module 10 . wall braces 300 are welded to walls 28 and 30 at intervals spaced along the walls &# 39 ; longitudinal extents . the wall braces 300 provide reinforcing support to the walls 28 and 30 . the wall braces 300 provide more substantial settings for attaching additional equipment than the unbraced walls 28 and 30 provide . the additional equipment can be attached either directly to the wall braces 300 or to one or more structural bolts 302 that are affixed to the wall braces 300 . the wall braces 300 also provide additional structural support for attaching the rollers 104 . [ 0064 ] fig7 a and 7b show rear and top views , respectively , of details of the interrelations of parts within the rabbet 102 . in fig7 a a rail 112 is disposed within the rabbet 102 . the stop 69 contacts the rail 112 when restricting the sliding motion of the drawer 100 . in fig7 b the rollers 104 supporting the drawer 100 are shown in relation to the rail 112 . [ 0065 ] fig8 a , 8b , and 8 c show rear end - on , side detail , and expanded side detail views , respectively , of the nut and bolt assembly 200 . the threaded hole of the asymmetrical nut 202 receives the cooperatively - dimensioned bolt 204 . a spring 208 is coiled about the bolt 204 in a compressed state between the asymmetrical nut 202 and the flange 66 . the spring 208 biases the asymmetrical nut 202 in an axial direction against the bolt &# 39 ; s threads . the biasing holds the asymmetrical nut 202 in a static orientation relative to the bolt 204 in the absence of other forces . a symmetrical nut 202 extends further downward to receive bolt 205 through hole 207 . a portion 210 of the asymmetrical nut 202 is seen to extend a greater distance from the hole 206 than does a portion 212 . in operation , the asymmetrical nut 202 is adjacent the truck side rail 68 . when positioned adjacent the truck side rail 68 , the open space around the asymmetrical nut 202 is insufficient to permit a complete rotation of the nut portion 210 about the bolt 204 , but is sufficient to permit a complete rotation of the nut portion 212 about the bolt 204 . rotating the bolt 204 causes a rotation as a whole of the nut and bolt assembly 200 until the portion 210 of nut 202 contacts the side rail 68 . rotating the bolt 204 further tightens the nut and bolt assembly 200 by moving the asymmetrical nut 202 towards the bolt 204 head . the tightening of nut and bolt assembly 200 thus secures together the side rail 68 and the flange 66 without needing to access the asymmetrical nut directly . once the side rail 68 and the flange 66 are secured by the tightened nut and bolt assembly 200 , the asymmetrical nut 202 is held against further rotation by frictional force between the asymmetrical nut 202 and the flange 66 . loosening of the nut and bolt assembly 200 , after being tightened to secure together the side rail 68 and the flange 66 , occurs upon counterrotating of the bolt 204 , since the asymmetrical nut 202 is held against also counterrotating . the loosening of nut and bolt assembly 200 can thus be accomplished without needing to access the asymmetrical nut 202 directly . counterrotating the bolt 204 loosens the asymmetrical nut 202 sufficiently to cease the holding effect of the frictional force on the asymmetrical nut 202 . the nut and bolt assembly 200 then rotates as a whole and the nut and bolt assembly 200 releases the securing of the side rail 68 and the flange 66 . [ 0067 ] fig9 shows an alternative handle 108 a and lock 110 a for utilization on a drawer front face 106 a . handle 108 a provides a different form than handle 108 for grasping and sliding the drawer 100 in the housing 14 . lock 110 a is positioned below handle 108 a , in contrast to the position of lock 110 . the face 106 a may be structured as an integrated unit which includes the lock 110 a and handle 108 a when desirable for manufacturing ease . [ 0068 ] fig1 a , 10b , and 10 c show a module 1000 according to a second embodiment of the present invention in rear , top and side views , respectively . fig1 a and 10b are depicting a pair of modules 1000 l and 1000 r in their respective orientations on the left and right sides of the truck bed 12 . the module 1000 l or 1000 r differ from the module 10 l or 10 r , respectively , in that the height 1002 of module 1000 is less than the height of the truck wheel well 72 . hence , the module 1000 has an inset 1003 for fitting around the wheel well 72 . a plurality of stands 1004 provide vertical support for the top 1022 . the stands 1004 are spaced along the longitudinal extent of the portion of the top 1022 which extends beyond the wall 1028 .
