Much freight is palletized and charactèri~tlcally picked up at a variety of CuBtOmer locat~on~, and then taken to an airport cargo area, or truck terrninal where the pallets are assembled with other goods to form a load. Time and space considerations require that structure be provided whereby freight can be weighed at the terminal dock prior to loading or, if desired, can be weighted on the pickup vehicle.
In some instances, it is more convenient to be able to weigh the freight on the pickup vehicle, and then provide the actual weight to the terminal personnel who are assembling the load, or to be able to provide the weight to personnel who are unloading the freight for subsequent shipment, such as by air where weight considerations are of paramount importance.
The apparatus of my invention can be located at the terminal or on the pickup vehicle to weigh the freight, and provide concurrent advantage~ not found in prior methods of freight weighing.
SUMMARY OF THE INVENTION
This invention relates to scale devices to be used at a stationary location or on a pickup vehicle such as a trailer, truck or other structure to obtain the weights of various items placed on the scale devices, and includes one or more retractible pneumatic scale assemblies for weighing.
The principal object of the invention is to provide scale devices that are capable of being stored out of the way until use.
A further object of the invention is to provide scale devices which permit of traffic thereon, in out of use position, without injury thereto.

DESCRIPTION OF THE PREFERRED EMBODIM~NT
Referring now more particularly to the drawings and FIGS. 1-4 thereof, a floor 10 which can be a vehicle floor or which could be the floor of a terminal dock is illustrated in FIG. 1 which, if a freight pickup vehicle, can be a truck, trailer or other structure, and onto which items are placed. The floor 10 is shown as carrying four scale devices 15 of the invention in recesses 16. The devices 15 are of generally rectangular configuration and each include a lower upturned U-shaped channel 18, which rests on the botto~ surface 19 of recess 16. A pneumatic lifting assembly 20 is provided which, in FIGS. 2-4, is shown as being an airbag of well known type carried inside of and resting on the channel 18, with a second channel 21 engaged therewith, also of U-shape extending upwardly, and separated from the side walls 23 of channel 18 by guide and wear plates 24.
The airbag 20 is connected to a source of air under pressure (not shown) to selectively provide air for expansion of the airbag to be described.
The channel 21 has a downturned cover plate 22 thereon also of U-shape, which extends over the outside of channel 18 between it and vertical walls 27 of ~ecess 16.
A load beam 25 is provided which extends along 4~L~
channel 21 with at least one load cell 26 engaged therewith, and which cell 26 is carried by a retainer plate 28 which is engaged with channel 21. The load cell 26 is of well known type, and preferably electronic, with leads (not shown) connected to a digital read out panel 35 to display the weiyht of the item or items being weighed.
Referring now more particularly to FIG. 5, another floor 100 i8 illustrated which includes a plurality of 10 devices 115, some eight in number being shown, which are carried in recesses 116 in the floor 100. In all other respects, the devices 115 are identical to those illustrated in FIGS. 2, 3, and 4, but for certain applications it may be desirable to utilize more than 15 four devices and, in actuality, as many as are desired and can be accommodated may be used.
Referring now more particularly to FIG. 6, another embodiment of scale device 215 is therein illustrated, which is carried in a recess 216 of a floor 200. The 20 device 215 is of generally rectangular configuration with a lower upturned U-shaped channel 218 which rests on the bottom surface 219 of recess 216. The channel 218 carries a load beam 225 thereon which extends therealong, and has a load cell 226 carried therein by 25 a retainer plate 227. The load cell 226 is of well known type and can be identical to load cell 26 previously described. The channel 218 on the outside thereof is provided with guide and wear plates 224, over which a cover plate 222 of U-shape extends 30 downwardly into recess 216.
A pneumatic lifting assembly 220 is provided which can be an airbag as described for assembly 20 and is carried on top of load beam 225 between it and the cover plate 222.
L ~
The airbag 220 is connected to a source of air under pressure (not shown) for selective expansion as desired to lift the plate 222 into contact with the items (not shown) to be weighed.
The mode of operation will now be pointed out.
Referring to FIGS. 1-4, the airbag 20 is normally in deflated condition as shown in FIGS. 2 and 3 so that the scale device 15 is entirely below the floor 10.
When the weight of a pallet (not shown) which contains various items ~o be weighted is desired, the pallet i8 picked up, and is placed on one or more of the scale devices 15. The airbag or bags 20 are inflated as shown in FIG. ~, to the desired predetermined pressure, and the channels 21 are elevated so that the tops 36 of the load cells 26 are engaged with the undersides 37 of cover plates 22, thereby transmitting the weight of the pallet and items thereon to the load cell or cells 26.
The weight of the freight item or items is displayed on panel 35 and may be recorded. The airbags 20, when in inflated condition, act as a cushion or shock absorber thereby providing protection to the scale devices 15 from impact loads. The airbags 20 are deflated, and the scale devices 15 are retracted to a position below the floor 10 level, where they are protected until use is again required.
Referring to FIG. 6, the airbag 220 is shown in inflated condition for engagement of the items to be weighed. The airbag 220 would start in deflated condition like airbag 20 and, when inflated, lifts cover plate 222 to engage the item or items (not shown) to be weighed, and the weight would be transmitted to the load beam 225, and thereby to the load cell 226 where the weight is ascertained and ,6~
transmitted to a read out panel (not shown) where it may be read by the operator. The airbag 220 can be deflated and cover plate 222 re~urn to floor level as desired.
It will thus be seen that apparatus has been provided with which the objects of the invention are attained.

DESCRIPTION OF THE PREFERRED EMBODIM~NT
Referring now more particularly to the drawings and FIGS. 1-4 thereof, a floor 10 which can be a vehicle floor or which could be the floor of a terminal dock is illustrated in FIG. 1 which, if a freight pickup vehicle, can be a truck, trailer or other structure, and onto which items are placed. The floor 10 is shown as carrying four scale devices 15 of the invention in recesses 16. The devices 15 are of generally rectangular configuration and each include a lower upturned U-shaped channel 18, which rests on the botto~ surface 19 of recess 16. A pneumatic lifting assembly 20 is provided which, in FIGS. 2-4, is shown as being an airbag of well known type carried inside of and resting on the channel 18, with a second channel 21 engaged therewith, also of U-shape extending upwardly, and separated from the side walls 23 of channel 18 by guide and wear plates 24.
The airbag 20 is connected to a source of air under pressure (not shown) to selectively provide air for expansion of the airbag to be described.
The channel 21 has a downturned cover plate 22 thereon also of U-shape, which extends over the outside of channel 18 between it and vertical walls 27 of ~ecess 16.
A load beam 25 is provided which extends along 4~L~
channel 21 with at least one load cell 26 engaged therewith, and which cell 26 is carried by a retainer plate 28 which is engaged with channel 21. The load cell 26 is of well known type, and preferably electronic, with leads (not shown) connected to a digital read out panel 35 to display the weiyht of the item or items being weighed.
Referring now more particularly to FIG. 5, another floor 100 i8 illustrated which includes a plurality of 10 devices 115, some eight in number being shown, which are carried in recesses 116 in the floor 100. In all other respects, the devices 115 are identical to those illustrated in FIGS. 2, 3, and 4, but for certain applications it may be desirable to utilize more than 15 four devices and, in actuality, as many as are desired and can be accommodated may be used.
Referring now more particularly to FIG. 6, another embodiment of scale device 215 is therein illustrated, which is carried in a recess 216 of a floor 200. The 20 device 215 is of generally rectangular configuration with a lower upturned U-shaped channel 218 which rests on the bottom surface 219 of recess 216. The channel 218 carries a load beam 225 thereon which extends therealong, and has a load cell 226 carried therein by 25 a retainer plate 227. The load cell 226 is of well known type and can be identical to load cell 26 previously described. The channel 218 on the outside thereof is provided with guide and wear plates 224, over which a cover plate 222 of U-shape extends 30 downwardly into recess 216.
A pneumatic lifting assembly 220 is provided which can be an airbag as described for assembly 20 and is carried on top of load beam 225 between it and the cover plate 222.
L ~
The airbag 220 is connected to a source of air under pressure (not shown) for selective expansion as desired to lift the plate 222 into contact with the items (not shown) to be weighed.
The mode of operation will now be pointed out.
Referring to FIGS. 1-4, the airbag 20 is normally in deflated condition as shown in FIGS. 2 and 3 so that the scale device 15 is entirely below the floor 10.
When the weight of a pallet (not shown) which contains various items ~o be weighted is desired, the pallet i8 picked up, and is placed on one or more of the scale devices 15. The airbag or bags 20 are inflated as shown in FIG. ~, to the desired predetermined pressure, and the channels 21 are elevated so that the tops 36 of the load cells 26 are engaged with the undersides 37 of cover plates 22, thereby transmitting the weight of the pallet and items thereon to the load cell or cells 26.
The weight of the freight item or items is displayed on panel 35 and may be recorded. The airbags 20, when in inflated condition, act as a cushion or shock absorber thereby providing protection to the scale devices 15 from impact loads. The airbags 20 are deflated, and the scale devices 15 are retracted to a position below the floor 10 level, where they are protected until use is again required.
Referring to FIG. 6, the airbag 220 is shown in inflated condition for engagement of the items to be weighed. The airbag 220 would start in deflated condition like airbag 20 and, when inflated, lifts cover plate 222 to engage the item or items (not shown) to be weighed, and the weight would be transmitted to the load beam 225, and thereby to the load cell 226 where the weight is ascertained and ,6~
transmitted to a read out panel (not shown) where it may be read by the operator. The airbag 220 can be deflated and cover plate 222 re~urn to floor level as desired.
It will thus be seen that apparatus has been provided with which the objects of the invention are attained.
