GOODS DISTRIBUTION VEHICLE

Abstract: A goods distribution vehicle has a housing (17) with a plat­ form (24) which may be driven between raised and lowered positions. Locking devices (50) can be extended to hold the platform in a raised position and include means (59) to prevent retraction of the locking means until the drive means applies upward lift to the platform. The floor of the housing has a raised front region (20) and the platform (24) may be raised or low­ ered to different levels at the front and back so that it may be horizontal or tilted.

Description: GOODS DISTRIBUTION VEHICLE The present invention relates to vehicles for goods distribution and transportation. The invention is particularly applicable to distribution vehicles such as lorries, trailers or semi-trailers for use in distributing goods in packaged form. Such vehicles comprise a housing within which goods may be loaded or unloaded through one or more access openings. Such access openings are commonly provided at the rear of the vehicle. The invention is particularly applicable to vehicles for transportation and/or distribution of goods, such as food, household items, clothing and similar products. It is desirable to facilitate loading and unloading of such goods into a vehicle for distribution and at the same time to make efficient use of the internal space within the vehicle housing and thereby of the load carrying capacity of the vehicle. Commonly distribution vehicles are used to convey such goods from one or more central warehouses to a variety of distribution points such as supermarket stores. To assist loading the goods they are frequently packed into mobile pallets or trays having wheels such that they may be rolled into and out of the vehicle. It is common practice for such goods to be loaded at a warehouse from a loading bay or dock which is raised above the ground so that the goods in pal lets, trays or other packaged form can be fed directly from a loading dock onto the floor of the vehicle. It is commonly necessary for an operator to lift one pallet, crate or package into another if the goods are to be stacked in more than one layer in the interior of the vehicle housing. Furthermore, in the case of semi-trailers which consist of a trailer unit for attachment to a tractor unit by use of an articulated connection, the housing on the trailer unit commonly has two floor regions ofdifferent levels. The front floor region adjacent the articulated joint is commonly raised above the rear floor region in order to accommodate the vehicle coupling below the floor of the front region of the trailer. In such cases it is necessary to pack goods within the vehicle housing on two different floor levels within the vehicle housing. The floor level of the front region of such a semi-trailer unit is normally fixed at a standard height to accommodate standard vehicle connections with trailer units. Similarly the loading dock height used at goods loading stations are frequently at a standard height to facilitate loading. The dock loading height may not necessarily correspond with the floor levels in the front and rear regions of such trailer units. It is an object of the present invention to provide an improved goods transporation or distribution vehicle with means for simplifying loading and unloading while utilising more than one tier within the housing. The present invention provides a vehicle for distributing and transporting goods, said vehicle having a housing providing an enclosure with one or more access openings to permit loading and unloading of packaged goods, said housing being provided with a floor on which goods may be loaded, a platform providing an additional support within the housing on which goods may be loaded, the platform being adjustable in height between a lowered position in which goods may be loaded or unloaded through said access opening onto or from said platform, and a raised position permitting more than one tier of goods within the housing, drive means for applying upward lift to raise the platform from the said lowered position to the raised position, means for lowering the platform from the raised position to the lowered position, and locking means arranged to provide a stop device movable between an extended position in which it holds the platform in the raised position and a retracted position in which the platform is free to be moved from the raised to the lowered position, said stop device including means to prevent retraction to allow lowering of the platform until said drive means applies upward lift to the platform. By such an arrangement, the platform may be positively held in the raised position without relying on continued application of upward lift by the drive means. The positive locking cannot be removed until upward lift is applied by the drive means. This provides additional safety to permit working by an operator below the raised platform in order to pack more goods onto the floor of the housing. Preferably said drive means includes one or more hydraulic piston and cylinder devices and preferably four piston and cylinder devices are provided, two on each side of the platform. Other suitable drive means may be employed such as pneumatic, electrical, or mechanical such as screw jacks or a chain drive on each side of the platform. Preferably the platform is movable substantially vertically up and down relative to a plurality of upstanding support elements fixed within the housing. Preferably the support means include guide means for guiding the upwards and downwards movement of the platform. Preferably the stop devices each comprise a retractable locking pin mounted on said support elements. Preferably the platform comprises a base with side members. The side members may be upstanding for use in retaining a plurality of goods on said platform. Preferably said access opening is at the rear of the vehicle and the platform is provided with a movable rear wall which may be moved to permit unobstructed access to the platform to allow rolling access for goods onto the platform when in the lowered position and may be moved to provide a retaining wall to maintain goods on the platform after loading. Preferably each said locking pin has an inner end arranged to extend inwardly past a mating part of the platform or a member carried thereby, when extended. Preferably each locking pin has at its inner end a projection arranged, when the pin is extended, to engage said mating part of the platform or member carried thereby and to prevent retraction of the pin twttl the platform is moved to clear the projection by application of upward lift by the said drive means. Preferably said pins are urged by spring means to said extended position. Preferably pneumatic means are provided to retract the locking pins against said spring means when it is required to lower a platform from said raised position. Preferably the locking pins are provided with a tapered surface at said inner end to permit movement of the pins to the retracted position by upward movement of the platform past said pins. The invention also provides a vehicle for distributing and transporting goods, said vehicle having a housing providing an enclosure with a rear access opening to permit loading and unloading of goods, said housing being provided with a floor on which goods may be loaded, said floor comprising a front region at a first level and a rear region at a second lower level, and a platform providing an additional support within the housing on which goods may be loaded, said platform being adjustable in height between a lowered position in which goods may be loaded or unloaded through said access opening onto or from said platform, and a raised position thereby permitting more than one tier of goods within the housing, support means fixed relative to said housing for supporting the front and rear ends of the platform when in the raised position, first drive means for lifting the front of the platform and second drive means for lifting the rear of the platform, the first and second drive means being arranged to provide different extent of travel for the front and rear of the platform whereby the platform may lie in a horizontal plane when raised but a tilted position when lowered, to permit use of the platform when lowered in loading onto the front region of the floor from a loading level at the rear of the vehicle which is not level with said front region of the floor. Preferably the front of the platform is aligned with the level of said front region of the floor when the platform is lowered, to permit access, preferably rolling access, via the platform onto said front region of the floor. Preferably the drive means at the rear of the platform has a greater extent of travel than the drive means at the front of the platform to allow the rear of the platform to lie in a lower position than the front of the platform when the platform is lowered. Preferably the drive means each comprise a hydraulic piston and cylinder device. Preferably at least four piston and cylinder devices are provided two on each side of the platform. Preferably the or each piston and cylinder device arranged to act on the rear of the platform has a greater stroke than the or each piston and cylinder device which acts on the front of the platform. Preferably switch means is located so as to respond to movement of the rear end of the platform, said switch means being arranged to control operation of the drive means which lifts the front of the platform so that when raising the platform the drive means acting on the front of the platform is actuated after a predetermined extent of travel of the rear of the platform. Preferably four upstanding support elements are provided within the housing to support the platform when raised, said support elements being provided two on each side of the platform. Preferably said support elements includes guide means for guiding the up and downward movements of the platform. Preferably the platform is provided with roller means for engaging said guide means to assist in guiding the platform movement. Preferably said roller means is arranged to locate the position of the platform in the longitudinal section of the vehicle. Preferably locating means are provided between said support elements and the platform to locate the platform in a lateral position when in the raised and lowered positions. Preferably retractable locking pins are provided to lock the platform in the raised position. Preferably said housing is provided with apertures adjacent said locking pins and the pins are arranged to extend outwardly through said apertures when the pins are disengaged from the platform whereby an operator can detect from outside the housing whether the pins are engaged with the platform. The invention is particularly applicable to distribution lorries or trailers or semi-trailers. The invention will now be described by way of example and with reference to the accompanying drawings in which: Figure 1 is a side view of a goods distribution vehicle showing the interior with a lifting platform in accordance with the present invention, Figure 2 shows in more detail one support member and part of the platform of Figure 1, Figure 3 is a scrap section on the line 3-3 in Figure 1, Figure 4 is a scrap section on the line 4-4 in Figure 1, Figure 5 is a similar scrap section taken on the line 5-5 in Figure 1, Figure 6 is a side view of a locking pin arrangement used in Figure 1, Figure 7 is a sectioned view of a guide roller and bearing pad arrangement used on the platform of Figure 1, Figure 8 is a front view of a control unit used in the vehicle of Figure 1, and Figure 9 is a flow diagram of an hydraulic circuit used in the vehicle of Figure 1. The goods distribution vehicle of this particular example consists of a semi-trailer unit 11 arranged for connection via an articulated joint 12 to a tractor unit at the front end of the vehicle. The semi-trailer of this example has three rear axles 13, 14 and 15 together with retractable support legs 16 at the front end. The vehicle has a hollow enclosed body formed by a generally rectangular housing 17 to which access is provided through a rear opening 18 closable by rear doors or shutters in a conventional manner. A handbrake 19 is provided for parking purposes. The trailer has two floor regions, a front raised floor 20 separated by a step 21 from a rear lower floor region 22. The front floor 20 is raised to accommodate the standard height of fixing via the articulated joint 12 to a tractor unit. It is however desirable when using the vehicle for goods distribution purposes to stack goods on both the floor regions 20 and 22. This particular example is particularly suited to the distribution of goods in packaged form and may be used for loading goods from a loading dock 23 at a warehouse and subsequent distribution at one or more locations such as supermarkets. The goods may be loaded onto the vehicle packed into crates or trolleys which are themselves rolled on wheels into the vehicle when loading and rolled out again when unloading. In accordance with the present invention, the interior of the vehicle is provided with an additional platform 24 which can be raised or lowered within the vehicle to provide an additional floor to permit stacking in more than one tier within the vehicle. In this particular example, the platform comprises a base member 25 of generally rectangular form extending across the full width of the vehicle and along the full length of the rear lower floor section 22. The platform 24 is provided with retaining sides 26 formed as an open framework together with a similar front retaining wall 27 and a hinged rear wall 28 capable of acting as a bridge between the platform 24 and a dock 23. The platform is supported on four vertical support members two on each side of the platform. The support members include two front support members 30 and two rear support members 31. Each of the support members is mounted at its lower end on the chassis of the vehicle immediately inside the side walls of the housing 17. The upper ends of the support members are interconnected by tie members 32 extending longitudinally and 33 extending transversely across the vehicle. Each of the support members extends vertically throughout substantially the full height of the interior of the vehice and as can be seen from Figures 3, 4 and 5 which each show a scrap section taken in a horizontal plane, the support members 30 and 31 each comprises a similarly shaped channel member located close to the outer wall 35 of the housing 17 so that the channel faces inwardly towards the platform 24 and contains a vertically extending hydraulic piston and cylinder 36. The lower end of the cylinder of each hydraulic unit 36 is mounted near the bottom of the support member 30 or 31 and the upper end of its projecting piston is connected to the upper end of a further channel member 37 which extends vertically within the channel of the support member 30 or 31. In this way, the piston of each hydraulic unit lies between the channel members 37 and the supporting members 30 or 31. The lower end of the base of each channel member 37 is secured to the sides 26 of the platform 24. In this way, the platform 24 is attached to the pistons of each of the four hydraulic units 36 so that operation of the hydraulic units can raise the platform when required. In order to guide the upwards and downwards movement of the platform 24, the sides 26 of the platform are provided with a guide and location unit as shown in Figure 7, adjacent each of the support members 30 and 31. Each of these units consists of a roller 40 arranged to rotate about a horizontal pin 41 and a bearing pad 42. The unit is fixed to the side 26 of the platform with the bearing pad 42 vertically above the roller 40. Similarly, the interior of the channel member of each of the support members 30 and 31 is provided with a fixed bearing microswitch 61 arranged to be contacted by the plates 52 when the pin is in the retracted position (a second microswitch, not shown, is located so as to be contacted by the plates 52 when the pin is in the extended position) so as to provide electrical signals to a control unit which will be described below. One of the rear support units 31 has a microswitch unit located within its channel member in the path of the roller 40 as the platform reaches its lowermost-position. This is indicated schematically by the numeral 62 in Figures 1 and 2. The microswitch is not provided on the front support elements 30 and it is used to enable tilting of the platform as will be described below. The operation of the platform is controlled by a control unit 70 which is normally mounted near the rear of the vehicle as indicated in Figure 1 so that it is readily available for access by a vehicle operator. The unit is shown more fully in Figure 8 and consists of a power on/off supply switch 71. Push buttons 72 and 73 are provided to raise or lower the platform respectively. A changeover switch 74 is provided to cause the locking pins 50 to be engaged or released and illuminated indicators 75 and 76 are provided to indicate whether the pins are locked or released. The hydraulic unit is shown more fully in Figure 9 and the hydraulic supply and valves are mounted in a recess 80 at the front end of the vehicle. The hydraulic supply consists of a hydraulic tank 81 having a supply line leading through a filter 82 to a pump 83 driven by a motor 84. The outlet of the pump 83 has a return line leading through a pressure relief valve 85 to the tank 81. The supply line from the pump 83 passes through a nonreturn valve 86 and filter 87 to a directional control valve 88 under the control of the raise or lower buttons 72 and 73 on the control unit shown in Figure 8. During the raise operation, pressurised fluid is provided by the valve 88 to a four-way flow divider 89 arranged to provide balanced flow to each of the four hydraulic cylinders 36. The divider 89 has four separate outlet lines 90,91,92 and 93 leading respectively to emergency changeover valves 94,95,96 and 97. Valves 95 and 96 are connected directly to the hydraulic cylinders 36 at the rear of the platform. The valves 94 and 97 are conected to the hydraulic units 36 at the front of the platform. Lines 90 and 93 which supply hydraulic fluid for the front units 36 each include a tilt control valve 98 operable in response to the microswitch 62 located on the rear support member 31. Each of the hydraulic cylinders 36 is provided with a safety valve 37 on its inlet so as to avoid uncontrolled flow of fluid from within the cylinder in the event of a hose burst or other uncontrolled leak. Each of the hydraulic cylinders 36 has an outlet connected to an exhaust line 100 which leads through an emergency changeover valve 101 back to the directional control valve 88. When the valve 88 is changed by operation of the lower switch 73 on the control unit, hydraulic fluid is allowed to exhaust from the cylinders 36 back to the tank 81 via a flow regulator 102 and line 103. The pressure lines 90,91,92 and 93 each have a connection to a circuit relief valve unit 104 to provide a return flow path via line 103 to the tank 81. Each of the emergency changeover valves 94,95,96 and 97 has a manually controlled lever to allow disconnection from the flow divider 89 and selective connection of each valve to an emergency hydraulic supply 105. Similarly the emergency changeover valve 101 can be operated by a manual lever to connect the exhaust line 100 to an emergency exhaust port 106 rather than to the tank 81. The tank 81, pump 83, motor 84, flow divider 89 and valves 94,95,96,97 and 101 are all housed in the recess 80 shown in Figure 1 so that they are accessible by an operator of the vehicle. Hydraulic fluid pressure lines lead from each of the valves 94,95,96,97 and 101 along the chassis of the vehicle to the respective hydraulic unit 36. The pneumatic piston for each locking pin unit is connected by an air supply line extending within the channel member of each support 30,31 to the pressurised air reservoir on the vehicle. In use, the platform is lowered to the position shown in Figure 1 where it may be tilted so that the rear of the platform is lower than the front of the platform as indicated in Figure 1. This is to accommodate difference in height between the level of the loading dock 23 and the front floor region 20 of the interior of the semi-trailer. Due to the standard attachment for semi-trailers to tractor units, the height of the front floor of the semi-trailer is commonly 1.5 metres above the ground. The height of the loading dock may well be less than this and may for example be 1.37 metres above the ground. To assist in loading from the dock 23 onto the front floor region 20 the platform 24 is lowered to its lowest extent on both the front and rear hydraulic units and this is the position shown in full lines in Figure 1. The goods may then be wheeled directly from the loading dock 23 onto the platform 24 and pushed along the platform 24. The rear of the platform is on the same level as the dock 23 whereas the front of the platform 24 is on the same level as the floor 20. The goods may thereby be wheeled directly along the length of the platform onto the front floor 20. When the front floor region 20 has been suitably loaded with goods the platform may itself be loaded with goods and then moved to the raised position. When the raise button 72 in the control unit is operated, this causes hydraulic fluid to be supplied by the pump 83 through the flow divider 89 to the lines 90,91,92 and 93. However, while the platform is in the position shown in Figure 1, the microswitch 62 is operated by the roller 40 which engages it to cause the valves 98 to switch the fluid supply away from the valves 94 and 97 back to the tank 81. In this way, no hydraulic pressure is applied to the cylinders 36 at the front of the platform although hydraulic pressure is supplied via lines 91,92 and the valves 95,96 to the hydraulic cylinders at the rear of the platform. This causes the rear of the platform to be moved upwardly until the platform reaches a level position. The engagement of the roller 40 with the microswitch 62 is arranged such that the switch is actuated when the platform reaches the level position and this causes the valves 98 to switch hydraulic supply back to the valves 94 and 97 as well as the valves 95 and 96. In this way hydraulic supply is then applied to all four cylinders 36 simultaneously and the platform is raised in a level position up to the upper position shown in dotted lines in Figure 1. As the platform moves past the locking pins it initially pushes the pins out of the path of the platform until the mating holes 58 in the sides of the platform are aligned with the pins at which time the pins are spring urged back into a projecting position thereby locking the platform in the upper position. Hydraulic supply is then terminated and the platform is held in the upper position. Goods may then be lowered onto the lower rear floor 22 of the vehicle with safety for the operator. Not only is the platform held by the locking pins, but the locking pins cannot be retracted due to the function of the lips 59 until hydraulic pressure is reestablished in the cylinders 36. Once the vehicle has been loaded, the rear access door may be closed and the vehicle connected to a tractor unit, if not already connected, and used for distribution. The procedure is generally reversed when wishing to unload the vehicle. When the control button 73 is operated to lower the platform, the platform initially is lowered in a level condition until the front end reaches the lower limits of travel. The rear hydraulic units are however able to allow continued downward movement of the rear of the platform until the platform reaches the same tilted position shown in Figure 1. The platform then assists in ready unloading of goods from the front floor region 20 in the same way as was previously described for loading. It will be appreciated that the invention is not limited to the details of the foregoing example. The extent to which the front and rear hydraulic units are arranged to tilt the platform may be varied to suit the particular loading heights used relative to the floor levels within the vehicle. The use of locking pins which cannot be released until hydraulic pressure is reestablished in the hydraulic cylinders provides additional safety. Furthermore, the provision of locking pins which are arranged to project through the four apertures in the exterior of the vehicle housing when disengaged from a locking position enable the operator to provide a simple visual check on the safety of the platform locking before working in the vehicle with a raised platform. The locking means may be provided with a plurality of lockable positions whereby the height at which the platform is locked in position may be varied. The vehicle housing may be rigid or non-rigid and may for example be curtain sided. When curtain sided, the combination of roller 40 and microswitch 62 would be replaced by other suitable sensing means such as for example a proximity switch. In the event of any failure by the normal hydraulic system through the pump 83, the manual controls on the valves 94,95,96,97 and 101 may be suitably adjusted and by connection of the ports 105 and 106 to an emergency hydraulic supply, the four hydraulic cylinders 36 can be separately operated and adjusted to provide any required change in position of the platform.
