- the view as shown in FIG. 1 has the panels inverted to show the underside.
- the truck box is of course not shown since this is well known to any person skilled in this art so that the truck box includes a front wall and two side walls together with a rear tail gate which is hinged at the bottom so that it can be folded downwardly to allow access into the truck box.
- the side walls of the truck box have a horizontal top surface which separates an inner wall of the truck box from the outer wall of the vehicle.
- the truck box has a front wall with a top surface with a front depending flange so that the top surface connects to the inside wall of the truck box at the front.
- each panel includes a side rail 13 which attaches to the top surface of the side wall of the truck box.
- the side rail is connected to the respective panel by a hinge 14 .
- Each panel has a rail 15 which is pivotally mounted at one end 16 to the respective panel.
- the rail 15 of the drivers side panel 11 is attached at its end 16 adjacent the rear of the panel.
- the rail 15 of the passenger side panel 12 is attached at its end 16 adjacent the forward end of the panel.
- Each rail has its opposite end, in a retracted position of the rail, latched as indicated at 17 to the underside of the panel.
- Each panel can be moved from a closed position lying across the top of the truck box where the inner side edges 18 of the panels are slightly overlapping.
- each rail extends across between the panels with the rail of the passenger side panel 12 at the front and the rail of the driver side panel 11 at the rear.
- Each of the panels includes a bracket 20 for receiving one end of an air cylinder (not shown) which extends from the bracket 20 to a corresponding bracket attached to the front wall of the truck box as described hereinafter.
- the panel 11 also includes a locking system generally indicated at 21 in the form of a handle 22 which operates a rod 23 for actuating locking elements 24 at spaced positions along the panel. Locking elements engage with cooperating members on the opposite panel.
- FIG. 4 there is shown in more detail the arrangement of the outside portion of the panel 12 including the rail 13 and the hinge 14 .
- the panels 11 and 12 as shown in the cross section of FIG. 4 are formed from a top or outer sheet 25 and an inner or bottom sheet 26 .
- Each of these sheets is moulded or vacuum formed from an ABS plastics material.
- the sheets are shaped to a required arrangement and then adhesively fastened together to provide the necessary structural strength.
- the inner sheet 26 is bent downwardly to form a depending channel portion 27 with a bottom wall 28 and an upstanding outermost wall or lip 29 .
- the outer sheet 25 has a depending lip 30 .
- An outer surface of the lip 29 is adhesively attached to an inner surface of the lip 30 at a junction line 31 .
- the height of the two lips is such that the lip 29 is contained underneath the bottom surface of the outer sheet 25 .
- the bottom edge 32 of the lip 30 terminates at a position coterminous with the bottom wall 28 .
- the lip 30 thus forms a wall surface with an outer surface 33 which is generally at right angles to the horizontal top surface 34 of the outer sheet 25 .
- the rail 13 is also formed from an outer sheet 35 and an inner sheet 36 .
- the outer sheet 35 is shaped to form an outer depending wall 37 which extends downwardly and outwardly to form a flange covering an outer flange 38 of the truck box indicated at 39 .
- the rail 13 includes a depending wall 40 .
- the spacing between the walls 37 and 40 is such that the top portion 41 of the rail covers a top surface 42 of the side wall of the truck box with the depending inside wall 40 along the inside surface 42 of the side wall and the flange 38 being covered by the outside wall portion 37 .
- the outer sheet is shaped to form a circular depression 44 to receive a bolt head 45 of a fastening bolt 46 .
- the inner sheet 36 is shaped so that a center portion 36 A contacts the underside of the sheet 35 and two side portions 36 B and 36 C depend downwardly to form channels with a bottom surface arranged to sit on the top surface 43 of the truck box side wall. These two channels of the inner sheet 36 thus support the center portion 41 of the outer sheet at a position spaced upwardly from the surface 43 of the side wall.
- a series of holes 36 D at spaced positions along the length thereof each having a captive bolt 36 E contained therein for engaging through a hole in the top surface 43 .
- the bolts 36 E which are arranged adjacent the inside surface 42 of the side wall of the truck box.
- a second row of bolts 46 adjacent the outer flange 38 .
- the arrangement of the bolts 46 and the captive bolts 36 E is such that they match the design of the truck box of a particular manufacturer.
- the bolt fasteners 46 are arranged to co-operate with four stake holes of the truck box.
- the bolts 36 E are arranged in a row at spacing to co-operate with a row of attachment holes for the truck box side walls.
- fastening arrangements are designed for example with a truck such as a Ford F150 to match the fastening holes already in place in the truck box side wall where those fastening holes are conventionally used to fasten a top rail over the truck box side wall supplied by the manufacturer Ford.
- a truck such as a Ford F150
- those fastening holes are conventionally used to fasten a top rail over the truck box side wall supplied by the manufacturer Ford.
- the fastening is effected by utilizing the bolt fasteners 46 which are of the butterfly-type and include spreading wings 46 A which pass through the hole in the side wall and then are spread by further tightening of the bolt 46 by actuation on the head 45 so as to pull the wings 46 A back up underneath the opening in the side wall to pull the head 45 down onto the side walls to clamp the rail in place.
- the head 45 includes a washer 45 A and an enclosing cap 45 B which engages around the head and includes a cover 45 C. It will be appreciated that the head 45 is accessible from the exterior of the truck box so that the first fastening can be effected by actuation of the bolt 46 to hold the bolts in place.
- the bolts 36 E simply pass through holes in the truck box side wall so that the end of the bolt is accessible from the inside of the truck box.
- the heads 36 F of the bolts 36 E are contained between the outer sheet 35 and the inner sheet 36 so as to be inaccessible from the exterior of the truck box. The installer can then apply a nut 36 G onto the bolt 36 E from the inside of the truck box.
- the two rows of fasteners provide a stable attachment of the rail to the truck box side wall since one wall is adjacent the inside and the other row is adjacent the outside thus preventing tilting of the rail on the side wall when forces are applied from the pivotal movement of the panel at the hinge 14 .
- the butterfly fasteners can be replaced by clips which are attached to the panel and simply pop into the hole in the side wall without the necessity for screw fastening, bearing in mind that the main fastening is effected by the bolts 36 E.
- This allows the installation to be simplified by pop fastening the rail onto the side wall so that it is held in place by the pop or snap fasteners and then can be fastened more vigorously by the bolts 36 E.
- the use of the pop fasteners also overcomes the difficulty that the area where these fasteners are located is inaccessible from the exterior or interior of the truck box.
- the hinge 14 comprises an inner piece 14 A which is attached to the surface 33 of the lip 30 and an outer piece 14 B which is attached to the depending wall 40 of the rail 13 .
- the hinge 14 is generally symmetrical and includes the inner piece 14 A and the outer piece outer piece 14 B together with a flexible interconnecting bridging member 14 C.
- the inner piece, the outer piece and the bridging piece are all continuous along the full length of the hinge and the hinge is continuous along the full length of the rail and the panel.
- the inner and outer piece each include a top lip portion 14 D and a depending flange portion 14 E which are adhesively attached to the respective end lip.
- the bridging piece 14 C is molded from a different plastics material so that it provides flexibility whereas the inner and outer pieces are formed of a material which is more rigid to provide effective attachment of those inner and outer pieces to the respective lip.
- the bridging piece 14 C is sufficiently flexible so that it can bend through 90° allowing the panel to move from the horizontal position shown in FIG. 4 to a raised vertical position (not shown) standing vertically upwardly at right angles to the position as shown.
- the hinge thus provides a continuous closure between the panel and the rail so that there is no possibility for the penetration of the moisture therebetween.
- the facing surfaces of the inner piece 14 A and the outer piece 14 B include co-operating flange members 14 F.
- the outer surface of the inner piece 14 A has a pair of flanges projecting outwardly and the inner surface of the outer piece 14 B includes a pair of flanges projecting inwardly.
- the flanges on the piece 14 A are spaced slightly further apart than the flanges on the piece 14 B so that when the panel is in the closed position as shown in FIG. 4 the flanges prevent upward and downward flexing movement of the hinge which would allow the outer edge of the panel to move upwardly and downwardly relative the rail.
- the flanges at the bottom abut and if the panel moves downwardly the panels at the top abut.
- FIG. 5 there is shown more detail of the end 16 of the rail 15 .
- the rail 15 carries a sleeve 15 A at the end 16 which attaches to a bracket 15 B by a bearing 15 C.
- the bracket 15 B includes a pair of legs 15 D and 15 E which are welded to a best plate 15 F.
- the base plate 15 F is mounted between the two sheets 25 and 26 so that it is received in a slightly recessed portion 26 A of the sheet 26 leaving the outside surface of the outer sheet 25 smooth. This provides therefore an effective technique for rigidly mounting the bracket 15 B and the bearing 15 C to the panel on the underside of the panel.
- the rail 15 is shown in FIG.
- the rail 15 is not at right angles to the panel 12 but instead the panel 12 is inclined upwardly and slightly inwardly when the rail 15 is horizontal as shown. In this way it will be appreciated that the panels in their erected position when the rails are erected are inclined upwardly and inwardly from the hinge 14 to the top edge which is spaced therefore slightly inwardly from the side wall of the truck box.
- FIG. 7 there is shown the receptacle 19 on the opposite panel 11 for attachment to the opposite end 17 of the rail 15 of FIG. 5 .
- a pin 17 A At the end 17 is mounted a pin 17 A and this is arranged for co-operation with a gate latch 19 A on the opposite panel 11 .
- the opposite panel 11 is also formed from the outer sheet 25 and the inner sheet 26 . These are shaped similarly to the corresponding sheets of the panel 12 but it will be appreciated that there are slight differences in view of the position and location of the rail and the latch 19 A.
- sheet 25 is also smooth and extends continuous out to the edge 18 of the panel.
- a lip 18 A which extends generally at right angles to the main body of the panel as defined by the outer surface 25 .
- the inner sheet 26 includes portions 26 B which are attached directly to the inside surface of the outer sheet 25 and recessed portions 26 C which form ribs 26 D which are spaced from the inside surface of the outer sheet 25 and thus provide structural ribs providing increased strength. Between the two ribs 26 D is provided the receptacle 19 for the latch 19 A.
- a base plate 19 B which is fastened to the inside surface of the outer sheet 25 and provides a support for the gate latch 19 A.
- each of the panels includes the outer layer 25 and the inner sheet 26 .
- the outer sheet 25 has a smooth outer surface 50 and the inner sheet 26 is bonded to an inner surface 51 of the outer sheet at portions 52 .
- recessed portions 53 which define a series of ribs 54 across the width of the panel.
- the ribs 54 extend from a position closely adjacent the hinge 14 at the outer edge inwardly through to the inner edge 18 .
- transverse rib 56 at a position spaced just outwardly of the rails 15 .
- the ribs 54 are recessed as indicated at 57 to define a recessed surface 58 against which the rails 15 rest in their retracted or stored position. In this position the rails are retracted below the rib 56 .
- the rib 56 acts as a stiffening member in the longitudinal direction of the panel.
- the panel 11 includes the down-turned lip 18 A which terminates at an edge 18 B.
- the inner sheet 26 is bonded to the inner surface of the sheet 25 at the inner surface 51 and also into the inner surface of the lip 18 A.
- the lip is defined by the thickness of both the inner and outer sheets to provide strengthening effect to that lip.
- the panel 12 is similarly formed from the outer sheet 25 and the inner sheet 26 and these sheets are molded to form a channel 60 into which the lip 18 A project.
- the channel 60 thus includes a depending wall 61 , a horizontal bottom wall 62 and an upstanding wall 63 .
- the upstanding wall 63 together with the bottom wall 62 and the depending wall 61 are all formed both from the inner and outer sheets to provide structural strength for the channel 60 .
- the outer sheet at the top of the outer wall 63 extends beyond the inner sheet to form a depending leg 64 and a smooth curved upper surface 65 which provides an attractive appearance to the edge of the channel 60 . In the closed position shown in FIG. 6 the lip 18 A projects over the smooth upper surface 65 along side the depending leg 64 .
- the panels are locked together by a plurality of toggle locks 24 as previously described.
- the toggle locks 24 comprise a body 24 A and a toggle locking member 24 B which moves into engagement with a plate 24 C on the underside of the bottom wall 62 of the channel.
- the toggle locking member 24 B moves in a direction controlled by a slot 24 D so that slides forwardly and moves downwardly underneath the plate 24 C. Movement of the toggle locking member 24 B is effected by rotation of the hexagonal shaft 23 which rotates a drive member in the body 24 A.
- Toggle locking members of this type are readily available and the details of operation of the movement of the toggle locking member are thus known to a person skilled in the art.
- the body 24 A is mounted on a plate 24 E clamped between the sheets 25 and 26 immediately adjacent the lip 18 A.
- FIG. 13 there is shown the mounting of the handle 22 between the outer sheet 25 and the inner sheet 26 in an area between two lips 66 and 67 of those sheets.
- the handle 22 is presented on the outside of a depending outside lip 66 of the panel 11 .
- the handle 22 attaches to a support and bearing 67 which allows the handle to rotate in the panel.
- a coupling 68 which attaches to the shaft 23 .
- the shaft 23 emerges through a hole 69 in a sheet 26 so that it extends underneath the panel to the toggle locking member 24 .
- FIGS. 9 , 10 , 11 and 12 there is shown the co-operation of the sheets 25 and 26 at the position adjacent the front and rear sides of the panel.
- the outer sheet 25 at each position where the cross sections are taken includes a depending lip 70 .
- This arrangement in effect provides a box section along the front edge and along the rear edge of each of the panels to provide structural strength therefore.
- the distance D 3 is smaller than the distance D 4 so that again the panels are supported at a slight pitch angle relative to the front wall of the truck box.
- the surface 73 of the inner or lower sheet 26 has step 74 which is arranged at a position immediately adjacent the inside surface of the front wall of the truck box to define a further channel portion 75 which extends slightly into the truck box to assist in locating the panels and to increase structural strength adjacent the front edge of the panels.
- the bracket 20 which attaches one end of the air assist cylinder (not shown).
- the bracket 20 includes a pin 20 A which attaches to a suitable coupling at the end of the cylinder.
- the pin 20 A is mounted on a flange 20 B of the bracket 20 .
- the flange 20 B is attached to a plate 20 C which is screw fastened to the surface 73 of the sheet 26 adjacent the lip 71 .
- the plate 20 C is thus flat against the surface 23 and the flange 20 B projects outwardly at right angles thereto so as to lie along the inside surface of the front wall of the truck box and supporting the pin 20 A so that it projects from the front wall of the truck box longitudinally of the truck box at a position spaced inwardly from the side wall.
- the pin 20 A thus supports the end of the cylinder which is attached to the panel so that the cylinder can apply force to the panel as it opens and closes.
- the bracket 80 for supporting a pin 81 from the wall of the truck box for receiving the other end of the cylinder attached to the pin 28 A.
- the bracket 80 includes a first bracket portion 82 which is attached on the outside of the front wall 83 of the truck box.
- the bracket further includes a plate portion 84 which clamps to the first portion 82 and supports the pin 81 inside the truck box at a position below the top edge of the truck box at the front wall of the truck box.
- the truck box includes the upstanding front wall 83 together with an outwardly or forwardly extending top flange 85 and a deep ending flange 86 from the front of the top portion 85 .
- the first bracket portion 82 is shaped to define a slot 87 which matches the flange 86 so that the slot can slide onto the flange 86 so that the leg 88 defining a rear side of the slot slides upwardly until it butt underneath the top plate 85 of the front wall of the truck box.
- a further leg 89 extends rearwardly from the slot into engagement with a front surface of the wall 83 of the truck box. This leg 89 together with the slot locate the first bracket portion 82 on the outside of the truck box wall at the front and present a receptacle 90 in front of the flange 86 for clamping to the plate portion 84 .
- the plate portion 84 includes a vertical plate 91 and a horizontal plate 92 which connect together at a corner which engages over the top edge of the wall 83 onto the top plate 85 of the truck box.
- the horizontal plate 92 is clamped to the receptacle 90 by a threaded fastener 94 .
- the arrangement thus provides a bracket for mounting a component on a truck box at the front wall 83 of the truck box, the front wall of the truck box having the horizontal top wall 85 and the outer depending flange 86 .
- the first member 82 has the bottom wall 89 of the body extending from a bottom of the depending flange 86 to the inner wall 83 of the truck box at a vertical portion thereof adjacent the top wall 85 .
- the body of the first member has the leg or wall portion 88 extending along an inner side of the slot and the body is hollow between the bottom wall 89 and the wall portion 88 .
- the first member has the flange 95 extending from the depending flange 88 away from the inner wall 83 and a bolt receptacle in the flange for receiving a bolt 89 extending downwardly from the top plate of the second plate member.
- the slot 87 is inclined downwardly and outwardly away from the inner wall.
- the connector comprises a pin 81 extending outwardly at right angles from the second plate into the truck box, but other connectors can also be used.
- FIGS. 14 and 15 there are shown two different techniques for mounting the end of the rail 15 at the receptacle for the end 17 on the underside of the panel.
- the attachment of the end 17 to the panel 11 is provided by way of a spring pin 96 which projects into a hole 97 in the end of the rail 15 .
- the spring pin 96 includes a handle 98 and an operating button 99 which allows the spring pin 96 to slide through a bracket 100 attached to the panel 11 .
- the bracket 100 includes a base plate 101 clamped between the outer wall 25 and the inner wall 26 . Depression of the button 99 releases the pin 96 by retracting locking elements 102 allowing the pin to be withdrawn from the end of the hole in the rail 15 .
- This arrangement of a pin which extends longitudinally along the rail can accommodate significant changes in temperature which occur in certain climates which can differentially expand the panel itself relative to the metal rail thus changing the distance between the bracket 100 and the end of the rail. Such changes in distance are accommodated by a change in the location of the pin 96 within the hole 97 in the end of the rail.
- FIG. 15 is shown an alternative arrangement for use where temperature changes are less dramatic which uses a simple gate latch 105 which receives and traps the pin 17 A shown in FIG. 5 .
- the arrangement in FIG. 15 is therefore preferred as a simple latching of the end of the rail 15 when it is moved to the retracted position since it can be simply held in place by engagement into the gate latch and can be readily released when required by the operator pressing on the gate latch.
- the gate latches can be operated by a suitable linkage pulled from one end.
- toggle latches which are operated by the handle 22 and which engage under plates on the panel 12 .
- This number can be increased to provide a more aggressive locking action.
- the toggle latches can be located closer to the ends so as to hold the ends more effectively attached to the ends of the truck box. In some cases this locking action may be insufficient to provide maximum security since it may still be possible for a user to apply a crowbar between the top edge of the truck box and the underside of the panels.
- an additional locking element may be provided directly between the panel 11 and a loop fastened to the tailgate. This may be provided by a pin which moves longitudinally of the panel into the loop providing a hole at right angles to the tailgate so that the pin when engaged in the loop prevents the panel from being lifted away from the tailgate.
- FIG. 18 is shown an alternative arrangement of the side rail 13 in which the mounting is simplified by use of a row of spring clip fasteners 46 B which snap fasten into holes 39 A in the truck rail 39 .
- the rail can be snap fastened in place by the row of spring clips 46 B and then clamped down by the second row of fasteners 36 E as previously described.
- the spring clips are thus attached to the rail from the underside in a slot 46 C using a captive head 46 D. This avoids forming a hole in the wall of the rail to the top surface, as in the embodiment of FIG. 4 , to provide a more attractive appearance and to avoid the fasteners 46 of FIG. 4 being exposed for possible tampering.

FIG. 18 is a cross sectional view similar to that ofFIG. 4 showing an alternative arrangement of themounting side rail 13. - In
FIG. 1 is shown a tonneau cover generally indicated at 10 which includes afirst panel 11 and asecond panel 12 which can be placed over a truck box so that thepanel 12 is on the drivers side and forms the left hand panel when viewed from the rear and thepanel 11 is on the passenger side and forms the right hand panel when viewed from the rear. The view as shown inFIG. 1 has the panels inverted to show the underside. - The truck box is of course not shown since this is well known to any person skilled in this art so that the truck box includes a front wall and two side walls together with a rear tail gate which is hinged at the bottom so that it can be folded downwardly to allow access into the truck box. The side walls of the truck box have a horizontal top surface which separates an inner wall of the truck box from the outer wall of the vehicle. Similarly the truck box has a front wall with a top surface with a front depending flange so that the top surface connects to the inside wall of the truck box at the front.
- The panels are of a general arrangement which is known from the above prior art and each panel includes a
side rail 13 which attaches to the top surface of the side wall of the truck box. The side rail is connected to the respective panel by ahinge 14. Each panel has arail 15 which is pivotally mounted at oneend 16 to the respective panel. Thus therail 15 of thedrivers side panel 11 is attached at itsend 16 adjacent the rear of the panel. Thus therail 15 of thepassenger side panel 12 is attached at itsend 16 adjacent the forward end of the panel. Each rail has its opposite end, in a retracted position of the rail, latched as indicated at 17 to the underside of the panel. Each panel can be moved from a closed position lying across the top of the truck box where theinner side edges 18 of the panels are slightly overlapping. In the raised position of the panels obtained by pivoting the panels about thehinge 14, the panels stand generally upwardly from the respective side wall of the truck box and therails 15 are moved to an extended position pivotal about theend 16 so that theend 17 is moved into engagement with the opposite panel at areceptacle 19. Thus in the raised position of the panels each rail extends across between the panels with the rail of thepassenger side panel 12 at the front and the rail of thedriver side panel 11 at the rear. Each of the panels includes abracket 20 for receiving one end of an air cylinder (not shown) which extends from thebracket 20 to a corresponding bracket attached to the front wall of the truck box as described hereinafter. - The
panel 11 also includes a locking system generally indicated at 21 in the form of ahandle 22 which operates arod 23 for actuatinglocking elements 24 at spaced positions along the panel. Locking elements engage with cooperating members on the opposite panel. - Turning now to
FIG. 4 , there is shown in more detail the arrangement of the outside portion of thepanel 12 including therail 13 and thehinge 14. Thepanels FIG. 4 are formed from a top orouter sheet 25 and an inner orbottom sheet 26. Each of these sheets is moulded or vacuum formed from an ABS plastics material. The sheets are shaped to a required arrangement and then adhesively fastened together to provide the necessary structural strength. At the outer edge of the panel at thehinge 14, theinner sheet 26 is bent downwardly to form a dependingchannel portion 27 with abottom wall 28 and an upstanding outermost wall orlip 29. In order to cooperate with this, theouter sheet 25 has a dependinglip 30. An outer surface of thelip 29 is adhesively attached to an inner surface of thelip 30 at ajunction line 31. The height of the two lips is such that thelip 29 is contained underneath the bottom surface of theouter sheet 25. Thebottom edge 32 of thelip 30 terminates at a position coterminous with thebottom wall 28. Thelip 30 thus forms a wall surface with anouter surface 33 which is generally at right angles to thehorizontal top surface 34 of theouter sheet 25. - The
rail 13 is also formed from anouter sheet 35 and aninner sheet 36. Theouter sheet 35 is shaped to form an outer dependingwall 37 which extends downwardly and outwardly to form a flange covering anouter flange 38 of the truck box indicated at 39. At an inner edge, therail 13 includes a dependingwall 40. The spacing between thewalls top portion 41 of the rail covers atop surface 42 of the side wall of the truck box with the depending insidewall 40 along theinside surface 42 of the side wall and theflange 38 being covered by theoutside wall portion 37. - At spaced positions along the length of the rail, the outer sheet is shaped to form a
circular depression 44 to receive abolt head 45 of afastening bolt 46. As shown inFIG. 1 there is a limited number ofsuch depressions 44 and in the embodiment shown there are four such depressions at spaced positions along the length of therail 13. - The
inner sheet 36 is shaped so that acenter portion 36A contacts the underside of thesheet 35 and twoside portions top surface 43 of the truck box side wall. These two channels of theinner sheet 36 thus support thecenter portion 41 of the outer sheet at a position spaced upwardly from thesurface 43 of the side wall. - Within the
channel 36C is provided a series ofholes 36D at spaced positions along the length thereof each having acaptive bolt 36E contained therein for engaging through a hole in thetop surface 43. - Thus there is provided a row of the
bolts 36E which are arranged adjacent theinside surface 42 of the side wall of the truck box. Thus there is a second row ofbolts 46 adjacent theouter flange 38. The arrangement of thebolts 46 and thecaptive bolts 36E is such that they match the design of the truck box of a particular manufacturer. Thebolt fasteners 46 are arranged to co-operate with four stake holes of the truck box. Thebolts 36E are arranged in a row at spacing to co-operate with a row of attachment holes for the truck box side walls. - These fastening arrangements are designed for example with a truck such as a Ford F150 to match the fastening holes already in place in the truck box side wall where those fastening holes are conventionally used to fasten a top rail over the truck box side wall supplied by the manufacturer Ford. When it is intended therefore to apply the tonneau cover of the present arrangement, therefore, the side rail which is already in place is removed exposing the holes in the top rail of the side wall which are then used without additional drilling or any other modification to fasten the
rail 13 to the side wall. - The fastening is effected by utilizing the
bolt fasteners 46 which are of the butterfly-type and include spreadingwings 46A which pass through the hole in the side wall and then are spread by further tightening of thebolt 46 by actuation on thehead 45 so as to pull thewings 46A back up underneath the opening in the side wall to pull thehead 45 down onto the side walls to clamp the rail in place. Thehead 45 includes awasher 45A and anenclosing cap 45B which engages around the head and includes a cover 45C. It will be appreciated that thehead 45 is accessible from the exterior of the truck box so that the first fastening can be effected by actuation of thebolt 46 to hold the bolts in place. Thebolts 36E simply pass through holes in the truck box side wall so that the end of the bolt is accessible from the inside of the truck box. Theheads 36F of thebolts 36E are contained between theouter sheet 35 and theinner sheet 36 so as to be inaccessible from the exterior of the truck box. The installer can then apply anut 36G onto thebolt 36E from the inside of the truck box. - When installed, therefore, it will be appreciated that the
bolts 36E are inaccessible from the exterior of the truck box so they cannot be removed from the exterior. When the cover is therefore closed and locked, the bolts are completely inaccessible thus preventing an unauthorized person from unbolting the cover and removing it from the truck box. - The two rows of fasteners provide a stable attachment of the rail to the truck box side wall since one wall is adjacent the inside and the other row is adjacent the outside thus preventing tilting of the rail on the side wall when forces are applied from the pivotal movement of the panel at the
hinge 14. - The butterfly fasteners can be replaced by clips which are attached to the panel and simply pop into the hole in the side wall without the necessity for screw fastening, bearing in mind that the main fastening is effected by the
bolts 36E. This allows the installation to be simplified by pop fastening the rail onto the side wall so that it is held in place by the pop or snap fasteners and then can be fastened more vigorously by thebolts 36E. The use of the pop fasteners also overcomes the difficulty that the area where these fasteners are located is inaccessible from the exterior or interior of the truck box. - The
hinge 14 comprises aninner piece 14A which is attached to thesurface 33 of thelip 30 and anouter piece 14B which is attached to the dependingwall 40 of therail 13. Thehinge 14 is generally symmetrical and includes theinner piece 14A and the outer pieceouter piece 14B together with a flexibleinterconnecting bridging member 14C. The inner piece, the outer piece and the bridging piece are all continuous along the full length of the hinge and the hinge is continuous along the full length of the rail and the panel. The inner and outer piece each include atop lip portion 14D and a dependingflange portion 14E which are adhesively attached to the respective end lip. - The
bridging piece 14C is molded from a different plastics material so that it provides flexibility whereas the inner and outer pieces are formed of a material which is more rigid to provide effective attachment of those inner and outer pieces to the respective lip. Thebridging piece 14C is sufficiently flexible so that it can bend through 90° allowing the panel to move from the horizontal position shown inFIG. 4 to a raised vertical position (not shown) standing vertically upwardly at right angles to the position as shown. - The hinge thus provides a continuous closure between the panel and the rail so that there is no possibility for the penetration of the moisture therebetween. There is continuous attachment of each of the inner and outer pieces of the hinge to the respective portion of the rail and the panel and the
bridging piece 14C is continuous. - The facing surfaces of the
inner piece 14A and theouter piece 14B includeco-operating flange members 14F. Thus the outer surface of theinner piece 14A has a pair of flanges projecting outwardly and the inner surface of theouter piece 14B includes a pair of flanges projecting inwardly. The flanges on thepiece 14A are spaced slightly further apart than the flanges on thepiece 14B so that when the panel is in the closed position as shown inFIG. 4 the flanges prevent upward and downward flexing movement of the hinge which would allow the outer edge of the panel to move upwardly and downwardly relative the rail. Thus if the panel moves upwardly, the flanges at the bottom abut and if the panel moves downwardly the panels at the top abut. - Turning now to
FIG. 5 , there is shown more detail of theend 16 of therail 15. Thus a portion of the panel is indicated at 12 and includes theouter sheet 25 and theinner sheet 26. Therail 15 carries asleeve 15A at theend 16 which attaches to a bracket 15B by abearing 15C. The bracket 15B includes a pair oflegs 15D and 15E which are welded to a best plate 15F. The base plate 15F is mounted between the twosheets portion 26A of thesheet 26 leaving the outside surface of theouter sheet 25 smooth. This provides therefore an effective technique for rigidly mounting the bracket 15B and the bearing 15C to the panel on the underside of the panel. Therail 15 is shown inFIG. 5 in the extended position projecting outwardly from thepane 12. It will be noted however that therail 15 is not at right angles to thepanel 12 but instead thepanel 12 is inclined upwardly and slightly inwardly when therail 15 is horizontal as shown. In this way it will be appreciated that the panels in their erected position when the rails are erected are inclined upwardly and inwardly from thehinge 14 to the top edge which is spaced therefore slightly inwardly from the side wall of the truck box. - Turning now to
FIG. 7 , there is shown thereceptacle 19 on theopposite panel 11 for attachment to theopposite end 17 of therail 15 ofFIG. 5 . At theend 17 is mounted apin 17A and this is arranged for co-operation with agate latch 19A on theopposite panel 11. Theopposite panel 11 is also formed from theouter sheet 25 and theinner sheet 26. These are shaped similarly to the corresponding sheets of thepanel 12 but it will be appreciated that there are slight differences in view of the position and location of the rail and thelatch 19A. - In
FIG. 7 it will be noted thatsheet 25 is also smooth and extends continuous out to theedge 18 of the panel. At theedge 18 of thepanel 11 is provided alip 18A which extends generally at right angles to the main body of the panel as defined by theouter surface 25. Theinner sheet 26 includesportions 26B which are attached directly to the inside surface of theouter sheet 25 and recessedportions 26C which formribs 26D which are spaced from the inside surface of theouter sheet 25 and thus provide structural ribs providing increased strength. Between the tworibs 26D is provided thereceptacle 19 for thelatch 19A. Embedded between thesheets outer sheet 25 and provides a support for thegate latch 19A. It will be noted again that with thegate latch 19A arranged at right angles to the length of therail 15 for engagement onto thepin 17A, there is an angle between thegate latch 19A and the panel which is symmetrical to the angle between theend 16 of the rail and thepanel 12 so that symmetrically thepanels rail 15 horizontal. - Turning now to
FIGS. 6 and 8 , the structure of each of the panels is shown in more detail. Thus each of the panels includes theouter layer 25 and theinner sheet 26. As shown inFIG. 8 theouter sheet 25 has a smooth outer surface 50 and theinner sheet 26 is bonded to aninner surface 51 of the outer sheet atportions 52. In between those two bonded sections recessedportions 53 which define a series ofribs 54 across the width of the panel. As shown inFIG. 1 theribs 54 extend from a position closely adjacent thehinge 14 at the outer edge inwardly through to theinner edge 18. There is in addition atransverse rib 56 at a position spaced just outwardly of therails 15. Also at the rails theribs 54 are recessed as indicated at 57 to define a recessedsurface 58 against which therails 15 rest in their retracted or stored position. In this position the rails are retracted below therib 56. Therib 56 acts as a stiffening member in the longitudinal direction of the panel. - As best shown in
FIG. 6 at theedges 18 of the panels, thepanel 11 includes the down-turnedlip 18A which terminates at anedge 18B. Theinner sheet 26 is bonded to the inner surface of thesheet 25 at theinner surface 51 and also into the inner surface of thelip 18A. Thus the lip is defined by the thickness of both the inner and outer sheets to provide strengthening effect to that lip. - The
panel 12 is similarly formed from theouter sheet 25 and theinner sheet 26 and these sheets are molded to form achannel 60 into which thelip 18A project. Thechannel 60 thus includes a dependingwall 61, ahorizontal bottom wall 62 and anupstanding wall 63. Theupstanding wall 63 together with thebottom wall 62 and the dependingwall 61 are all formed both from the inner and outer sheets to provide structural strength for thechannel 60. The outer sheet at the top of theouter wall 63 extends beyond the inner sheet to form a dependingleg 64 and a smooth curvedupper surface 65 which provides an attractive appearance to the edge of thechannel 60. In the closed position shown inFIG. 6 thelip 18A projects over the smoothupper surface 65 along side the dependingleg 64. The underside of thesheet 26 sits on thesmooth surface 65 to provide a closure between the panels. Thelip 18A projects downwardly into the channel so as to provide in effect a labyrinth seal to prevent moisture from penetrating between the panels. Any moisture entering thechannel 60 collects within the channel and is preventing from engaging over theupstanding wall 63 of the channel into the area between the panels. The channel has a discharge at the rear end over the tailgate so that any moisture collecting therein can run along the vehicle to the tailgate for discharge over the tailgate to prevent it entering into the truck box between the panels. - The panels are locked together by a plurality of toggle locks 24 as previously described. The toggle locks 24 comprise a
body 24A and atoggle locking member 24B which moves into engagement with aplate 24C on the underside of thebottom wall 62 of the channel. Thetoggle locking member 24B moves in a direction controlled by aslot 24D so that slides forwardly and moves downwardly underneath theplate 24C. Movement of thetoggle locking member 24B is effected by rotation of thehexagonal shaft 23 which rotates a drive member in thebody 24A. Toggle locking members of this type are readily available and the details of operation of the movement of the toggle locking member are thus known to a person skilled in the art. Thebody 24A is mounted on aplate 24E clamped between thesheets lip 18A. - Turning now to
FIG. 13 there is shown the mounting of thehandle 22 between theouter sheet 25 and theinner sheet 26 in an area between twolips handle 22 is presented on the outside of a depending outsidelip 66 of thepanel 11. Thehandle 22 attaches to a support and bearing 67 which allows the handle to rotate in the panel. At the end of thesupport 67 is provided acoupling 68 which attaches to theshaft 23. Theshaft 23 emerges through ahole 69 in asheet 26 so that it extends underneath the panel to thetoggle locking member 24. - Turning now to
FIGS. 9 , 10, 11 and 12, there is shown the co-operation of thesheets outer sheet 25 at each position where the cross sections are taken includes a dependinglip 70. This co-operates with a portion of thesheet 26 which is spaced from theunderside 51 of thesheet 25 but includes anupstanding lip 71 which is bonded to thelip 70 and extends upwardly toward theunderside 51 of thesheet 25. This arrangement in effect provides a box section along the front edge and along the rear edge of each of the panels to provide structural strength therefore. By comparing thecross sections sheet 26 inFIG. 12 which is closer to the side wall of the truck provides a distance D1 between thetop surface 72 of thesheet 25 and thebottom surface 73 of thesheet 26 at thelip 71 where the distance D1 is smaller than the distance D2 ofFIG. 11 . In this way it will be appreciated that thesurface 73 of theinner sheet 26 sits on the top edge of the tailgate so that thesurface 72 of the outer or top sheet of the panel increases in height relative to the top surface of the tailgate from the outside wall of the truck box towards the center of the truck box. This provides a slight pitch to the panels acting to assist in shedding water to the sides of the truck box. Similarly at the front of the truck box where the cross sections ofFIGS. 9 and 10 are taken, the distance D3 is smaller than the distance D4 so that again the panels are supported at a slight pitch angle relative to the front wall of the truck box. Also it will be note dinFIG. 10 that thesurface 73 of the inner orlower sheet 26 hasstep 74 which is arranged at a position immediately adjacent the inside surface of the front wall of the truck box to define afurther channel portion 75 which extends slightly into the truck box to assist in locating the panels and to increase structural strength adjacent the front edge of the panels. - While the cross sections of the panel are taken in relation to the
panel 11 inFIG. 2 , it will be appreciated that the shape of thepanel 12 ofFIG. 3 is symmetrical in respect to these particular elements and in relation to the shaping of the inner and outer sheets, the only differences being in relation to the locking arrangement and the connection along the center line and in other respects the panels are substantially symmetrical. - Also shown in
FIG. 9 is thebracket 20 which attaches one end of the air assist cylinder (not shown). Thebracket 20 includes apin 20A which attaches to a suitable coupling at the end of the cylinder. Thepin 20A is mounted on aflange 20B of thebracket 20. Theflange 20B is attached to aplate 20C which is screw fastened to thesurface 73 of thesheet 26 adjacent thelip 71. Theplate 20C is thus flat against thesurface 23 and theflange 20B projects outwardly at right angles thereto so as to lie along the inside surface of the front wall of the truck box and supporting thepin 20A so that it projects from the front wall of the truck box longitudinally of the truck box at a position spaced inwardly from the side wall. Thepin 20A thus supports the end of the cylinder which is attached to the panel so that the cylinder can apply force to the panel as it opens and closes. - Turning now to
FIGS. 16 and 17 , there is shown abracket 80 for supporting apin 81 from the wall of the truck box for receiving the other end of the cylinder attached to the pin 28A. Thebracket 80 includes afirst bracket portion 82 which is attached on the outside of thefront wall 83 of the truck box. The bracket further includes aplate portion 84 which clamps to thefirst portion 82 and supports thepin 81 inside the truck box at a position below the top edge of the truck box at the front wall of the truck box. - Thus the truck box includes the upstanding
front wall 83 together with an outwardly or forwardly extendingtop flange 85 and adeep ending flange 86 from the front of thetop portion 85. Thefirst bracket portion 82 is shaped to define a slot 87 which matches theflange 86 so that the slot can slide onto theflange 86 so that theleg 88 defining a rear side of the slot slides upwardly until it butt underneath thetop plate 85 of the front wall of the truck box. Afurther leg 89 extends rearwardly from the slot into engagement with a front surface of thewall 83 of the truck box. Thisleg 89 together with the slot locate thefirst bracket portion 82 on the outside of the truck box wall at the front and present areceptacle 90 in front of theflange 86 for clamping to theplate portion 84. - The
plate portion 84 includes avertical plate 91 and ahorizontal plate 92 which connect together at a corner which engages over the top edge of thewall 83 onto thetop plate 85 of the truck box. Thehorizontal plate 92 is clamped to thereceptacle 90 by a threadedfastener 94. This arrangement provides a simple mounting of the bracket to the front wall of the truck box without the necessity for drilling the truck box or forming other shapes or changes in the truck box itself. (It simply can be clamped onto the front wall of the truck box by sliding the slot portion or first portion underneath theflange 86 and then by screwing theplate 92 down onto thereceptacle 90 to hang theplate 91 downwardly on the inside of the truck box to present thepin 81 rearwardly of the truck box for engaging the end of the air cylinder. - The arrangement thus provides a bracket for mounting a component on a truck box at the
front wall 83 of the truck box, the front wall of the truck box having the horizontaltop wall 85 and theouter depending flange 86. - The
first member 82 has thebottom wall 89 of the body extending from a bottom of the dependingflange 86 to theinner wall 83 of the truck box at a vertical portion thereof adjacent thetop wall 85. - The body of the first member has the leg or
wall portion 88 extending along an inner side of the slot and the body is hollow between thebottom wall 89 and thewall portion 88. - The first member has the
flange 95 extending from the dependingflange 88 away from theinner wall 83 and a bolt receptacle in the flange for receiving abolt 89 extending downwardly from the top plate of the second plate member. - The slot 87 is inclined downwardly and outwardly away from the inner wall.
- The connector comprises a
pin 81 extending outwardly at right angles from the second plate into the truck box, but other connectors can also be used. - Turning now to
FIGS. 14 and 15 there are shown two different techniques for mounting the end of therail 15 at the receptacle for theend 17 on the underside of the panel. In the arrangement shown inFIG. 14 , the attachment of theend 17 to thepanel 11 is provided by way of aspring pin 96 which projects into ahole 97 in the end of therail 15. Thespring pin 96 includes ahandle 98 and an operating button 99 which allows thespring pin 96 to slide through abracket 100 attached to thepanel 11. Thebracket 100 includes abase plate 101 clamped between theouter wall 25 and theinner wall 26. Depression of the button 99 releases thepin 96 by retractinglocking elements 102 allowing the pin to be withdrawn from the end of the hole in therail 15. This arrangement of a pin which extends longitudinally along the rail can accommodate significant changes in temperature which occur in certain climates which can differentially expand the panel itself relative to the metal rail thus changing the distance between thebracket 100 and the end of the rail. Such changes in distance are accommodated by a change in the location of thepin 96 within thehole 97 in the end of the rail. - In
FIG. 15 is shown an alternative arrangement for use where temperature changes are less dramatic which uses asimple gate latch 105 which receives and traps thepin 17A shown inFIG. 5 . The arrangement inFIG. 15 is therefore preferred as a simple latching of the end of therail 15 when it is moved to the retracted position since it can be simply held in place by engagement into the gate latch and can be readily released when required by the operator pressing on the gate latch. The gate latches can be operated by a suitable linkage pulled from one end. - As best shown in
FIG. 2 there are two toggle latches which are operated by thehandle 22 and which engage under plates on thepanel 12. This number can be increased to provide a more aggressive locking action. In addition the toggle latches can be located closer to the ends so as to hold the ends more effectively attached to the ends of the truck box. In some cases this locking action may be insufficient to provide maximum security since it may still be possible for a user to apply a crowbar between the top edge of the truck box and the underside of the panels. In this case an additional locking element may be provided directly between thepanel 11 and a loop fastened to the tailgate. This may be provided by a pin which moves longitudinally of the panel into the loop providing a hole at right angles to the tailgate so that the pin when engaged in the loop prevents the panel from being lifted away from the tailgate. - In
FIG. 18 is shown an alternative arrangement of theside rail 13 in which the mounting is simplified by use of a row ofspring clip fasteners 46B which snap fasten intoholes 39A in thetruck rail 39. Thus the rail can be snap fastened in place by the row of spring clips 46B and then clamped down by the second row offasteners 36 E as previously described. The spring clips are thus attached to the rail from the underside in aslot 46C using acaptive head 46D. This avoids forming a hole in the wall of the rail to the top surface, as in the embodiment ofFIG. 4 , to provide a more attractive appearance and to avoid thefasteners 46 ofFIG. 4 being exposed for possible tampering. - Since various modifications can be made in my invention as herein above described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without department from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
