The plurality of walls extend between the floor and the roof and include a front wall, a rear wall, and side walls extending between the front and rear walls. Roofs, floors, and walls form internal storage spaces. The walls define a discharge opening. The partition wall extends from the front wall toward the rear wall and extends between the floor and the roof to form a lower compartment of a predetermined volume with an upper compartment of a predetermined volume. The partition may move in the vertical direction to increase the volume of one of the upper and lower compartments communicating with the opening.

Description

Storage structure of multiple compartments

The present invention relates to a garbage truck for collecting garbage and recyclable materials from residential or other commercial facilities and transporting them to a central processing plant such as a garbage can, a combustion furnace or a recycling facility. More specifically, the present invention relates to a multi-compartment storage structure having an upper compartment and a lower compartment separated by a vertically movable partition, the partition defining a volume of an upper compartment or a lower compartment communicating with the discharge opening, This waste material can be augmented to make it easier to unload.

Until recently, communities and provinces have developed programs to collect and separate recyclable materials to minimize the consumption of natural resources and the depletion of landfills. The recycling program has been delegated to several states and communities. However, vehicles used to collect and transport wastes or wastes are generally not suitable for use in collecting and transporting recyclable materials. Devices and vehicles for collecting and transporting wastes typically include compartments of a single volume in which all the materials collected are stored and transported. As a result, the collected material unloaded to the central processing plant is mixed together in one large single compartment.

In contrast to general waste, it is desirable that the recyclable material be contained separately in different compartments. For example, when relying on a local recycling facility, it is often acceptable to mix recyclable glass, plastic, and aluminum materials together. However, these three materials must be separated from species or prints. As a result, special vehicles with multiple compartments are required to collect recyclable materials. Since the amount of each item may vary from day to day or from place to place, it is also advantageous to provide a compartment with an adjustable volume to provide a variable capacity for containing the item. Although it is possible to separate different materials into multiple compartments, the storage capacity of the storage structure is also reduced due to its misfire. In addition, as the number of walls and corners in individual compartments increases, less collection material can be squeezed into the storage structure with internal volume, resulting in storage of multiple compartments in a structure for collecting and separating recycled materials The structure is uneconomic and irrelevant for the collection of non-recyclable waste that does not need to be separated. Thus, communities may be required to own and operate individual vehicles, ie, single compartment garbage trucks for collecting garbage entirely from one location, and multiple compartment vehicles for collecting recyclables and garbage from multiple locations. Keeping these separate vehicles of different functions in operation is expensive.

When garbage is filled into each compartment of a multi-compartment vehicle, the garbage tends to be squeezed. Also, in order to increase the volume of material that can be transported and contained in the storage structure, the garbage truck typically includes rams or compressors to further compress the garbage into individual compartments. As the number of compartments in the storage structure increases, the need to further compress the garbage material increases. The squeezing of the waste material allows the greater amount of waste material to be contained within the storage structure, thereby reducing the overall cost and frequency of operations associated with collecting the waste. However, when the waste material is squeezed in the storage structure, it becomes difficult to unload the waste from the vehicle. As a result, the garbage squeezed in the storage structure should not be agglomerated and squeezed so that the material can be pushed out of the storage structure and unloaded. Additional time and tools are needed to crack the squeezed or recyclable material, thus increasing the operating cost of the garbage collection vehicle.

In the case of a storage structure having a hopper discharge opening that narrows toward the opening, unloading the squeezed waste from this storage structure becomes more complicated. Because these discharge openings are typically funnel-shaped, the squeezed waste material in the storage structure is substantially compressed as the material approaches the opening. As a result, storage structures that utilize hopper-shaped discharge openings as part of the bottom of the storage structure become particularly difficult to unload (garbage material).

The present invention is an improved multiple compartment storage structure for a garbage truck. The structure includes a floor, a roof, a plurality of walls, and a bulkhead. The plurality of walls extend between the floor and the roof and include a front wall, a rear wall, and side walls between the front wall and the rear wall. The roof, floor, and walls together form an internal storage space. The walls form a discharge opening. The partition wall extends from the front wall to the rear wall and is positioned between the floor and the roof to divide the internal storage space into an upper compartment and a lower compartment having a predetermined volume, It can be moved vertically to increase the volume of a compartment. In use, discharging waste from such storage structures discharges waste from the lower storage compartment out of the discharge opening, lowering the bulkhead to increase the volume of the upper storage compartment communicating with the discharge opening, and discharging waste from the upper storage compartment And discharging it out of the discharge opening. As a result, the stored squeezed waste or other material in the compartment is more easily unloaded.

Throughout the specification, various terms such as "top", "bottom", "front", "rear", "left", "right" These terms are used to denote directions relative to the drawings and are not intended to limit the direction of the invention. Rather, these terms are provided for the purpose of clarifying the relationship between the compartment and the member of the garbage collection vehicle. For example, the terms "right" and "left" are used to describe the relationship between the elements when viewed from the rear end of the garbage collection vehicle.

The lifting jack 23 is mounted between the frame 22 of the storage structure 18 and the press 16 toward the front end of the undercarriage 12. The lifting jack 23 is provided with a presser 16 and a storage structure 18 which are close to the front end of the undercarriage 12 around the pivot 25 so that the waste can be unloaded from the rear end of the storage structure 18, . The lifting jack 23 is also mounted between the frame 22 and either the compactor 16 or the storage structure 18 that tilts the storage structure 18 to one side to discharge the waste out of the side discharge opening. As can be appreciated, the lifting jack 23 may also use pneumatic means or other means to tilt the compactor 16 and the storage structure 18. The wheel 24 is rotatably mounted on the cap 20 and the frame 22 to support the cap 20 and the frame 22 above the wheel.

The stack 14 generally includes a bottom floor 26, a plurality of outer walls 27, inner partitions 28 and 29, rollers 30 and lifting lugs 32a and 32b A large dumpster or a rectangular cart containing a plurality of cartridges. The bottom 26 and the outer wall 27 define the storage capacity or volume of the stacker 14. The partition wall 28 extends between the bottom 26 and the outer wall 27 so as to divide the storage volume of the stacking container 14 in the forward and backward halves. The partition 29 extends from the partition 28 to the front end of the outer wall 27 to divide the remaining front half of the stack 14 into two parallel compartments. Overall, the partitions 28, 29 communicating with the bottom 26 and the outer wall 27 are divided into three separate compartments, a front right compartment 34a, a front left compartment 34b, a rear compartment 34c As shown in FIG. Each compartment 34a, 34b, 34c is constructed and designed to a size that can accommodate the waste to be separated and the recyclable material. Preferably, the rear compartment 34c extends along the entirety of the rear half of the stacking bin 14, which usually contains non-recyclable waste. The front right compartment 34a and the front left compartment 34b divide the remaining front half of the stacking bin 14 which houses paper and glass or plastic material, respectively.

The roller 30 extends downwardly from the support tube 14 and the bottom 26 of the barrel above its surface. The rollers 30 allow the stacking cans 14 to be separated from the vehicle 10 to move to a loading and filling station that is otherwise inaccessible. The lifting lugs 32a and 32b are preferably cylindrical or tubular and are manufactured to have a size capable of accommodating the engaging members of the lifting device 15. [

The lifting lugs 32a and 32b are mounted on the side of the outer wall 27. [ Preferably, the lifting lugs 32a, 32b are positioned toward the rear of the stacking bin 14. [ The lifting lugs 32a and 32b are lifted by the lifting device 15 such that the lifting bar 14 is lifted above the press 16 and can be unloaded into the press 16 as shown by imaginary line 36 So that it can be detachably coupled. Alternatively, the loading cylinder 14 may have a side loading bin fixed to one side or both sides of the press 16, wherein the compartment is provided with a side surface of the press 16 until it reaches the upper side of the press 16 And the stacker 14 is inclined to dispense the material from the compartment into the press 16. As can be appreciated, the loading cylinder 14 may also be fixedly attached to the elevating device 15. [

The lifting device 15 lifts the contents of the stacking cans 14 above the press 16 to unload the contents of the stacking cans 14 into the compacting device 16, As shown in FIG. 2, the elevating device 15 preferably includes a pair of lifting arms or forks 40a, 40b pivotally extending in front of the cap 20. The forks 40a and 40b are engaged and connected with the lifting lugs 32a and 32b. The forks 40a and 40b are raised by the power unit and are preferably hydraulic piston / cylinder assemblies that are hydraulically controlled by control means within the cap 20, as is generally known in the art. In operation, The vehicle 10 is driven to the loading cylinder 14 so that the forks 40a and 40b are engaged with the lifting lugs 32a and 32b. The power unit then moves the forks 40a and 40b and the stacking cans 14 up and down the cap 20 as shown by phantom line 36 to empty the contents of the compartment 34 into the presser 16, And is used to lift it backward.

Compressor 16 is mounted to frame 22 between storage structure 18 and cap 20 and includes a bottom 44, a front wall 46, a roof 48, a side wall 50 A rear wall 52, a forewar chute partitioning wall 54, a bottom 56 of the upper chute, a wall 58 of the intermediate chute, and ram assemblies 60a, 60b, 60c (Shown in FIG. 2). The bottom 44 and the front wall 46, the roof 48, the side wall 50 and the rear wall 52 receive and form the press 16. The wall 54 of the front shoot extends downwardly from the roof 48 between the side walls 50. The bottom 56 of the upper chute extends horizontally from the rear wall 58 to the lower end of the dividing wall 54 of the front shoot. The middle chute wall 58 extends from the roof 48 to the bottom 56, (52), the wall (54) of the front chute, and the intermediate side wall (50). The wall 54 of the front chute, the top floor 56 and the wall 58 of the middle chute are used to connect the press 16 to three compression compartments or chutes 64: a rear right compression set 64a, (Shown in Fig. 2), and a rear squeeze chute 64c. The roof 48 includes openings 66a, 66b, and 66c (shown in FIG. 2) that communicate with the chutes 64a, 64b, and 64c, respectively. The rear wall 58 also includes openings 68a, 68b and 68c (shown in FIG. 2) communicating with the lower ends of the chutes 64a, 64b and 64c, respectively. The opening 68c is such that the openings 68a and 68b are adjacent the bottom 52 adjacent the bottom 62 and that the openings 68a, 68b and 68c respectively align with the ram assemblies 60a, 60b and 60c desirable.

The ram assemblies 60a, 60b, 60c (shown schematically) are conventionally known in the art and are provided for pushing the waste and recyclable material in a preselected direction. The ram assembly 60c is positioned toward the lower end of the chute 64c and includes a cover plate 70c and a ram 72c. The cover plate 70c extends between the side walls 50 and slightly slopes downward and rearward. The cover plate 70c protects the ram 72c while covering the ram 72c while sending the waste and recycled material to the front of the ram 72c when the ram 72c is in the retracted position. Randomly illustrated ram 72c is well known in the art. The ram 72c extends from the lower cover plate 70c in the chute 64c adjacent to the bottom 44 to the rear wall 52. In a conventional construction, the ram 72c includes a fluid operated piston and a cylinder assembly, which piston is connected to the front blade of the ram to move the ram backward. The ram 72c is preferably controlled by a hydraulic or electrical control means forming a cap 20 that operates the ram 72c. The ram 72c pushes the waste and recyclable material in the chute 64c into the storage structure 18 from the opening 68c. As can be appreciated, the ram 72c may also be configured to extend rearwardly into the storage structure 18 rearwardly of the rear wall 52 to further reduce the volume of waste and recyclable material. The ram assemblies 60a and 60b are similar to the ram assemblies 60c but are located within the lower ends of the chutes 64a and 64b, respectively.

The storage structure 18 is mounted to the frame 22 adjacent the rear wall 44 of the press 16 and includes a bottom 80, a front wall 82, a roof 84, side walls 86, 88), an intermediate partition wall 90, a movable partition 92a, 92b (see FIG. 2), and a drop floor assembly 94a, 94b (see FIG. The bottom 80, the front wall 82, the roof 84, the side walls 86, and the back door assembly 88 form an internal storage space 96 of the storage structure 18. The front wall 82 includes an upper right opening 98a, an upper left opening 98b and a lower opening 98c (see FIG. 2). The openings 98a, 98b and 98c are arranged so as to communicate with the openings 68a, 68b and 68c, respectively, so that the ram assemblies 66a, 66b and 66c communicate with the inner storage space It is preferable to push it into the pressing member 96 and press it. Although the side wall 86 is shown in a straight line from the bottom 80 to the roof 84, it may alternatively be bent from the bottom 80 to the roof 84 or outward.

The back door assembly 88 includes a curved wall 100 with an inner surface. The wall 100 is pivoted about a pivotal axis 102 relative to the roof 84 and side walls 86 and is detachably coupled to the bottom 80 and the side wall 86 at the latch 104. The wall 100 surrounds the rear portion of the internal storage space 96 to accommodate waste and recyclable material in the internal storage space 96. The hinge 102 and the latch 104 allow the wall 100 to be raised so that the discharge opening 106 is open and through which the recyclable material is evacuated from the internal storage space 96 Can be. Preferably, the rear door assembly 88 is actuated hydraulically to raise the wall 100 to open the discharge opening 106. The inner surface of the wall 100 is curved so that the waste pushed rearward by the ram 72a and the recyclable material are lifted along the wall 100 to be lifted above the drop floor assembly 94 at a constant interval Falls. The wall 100 extends vertically between the bottom 80 and the roof 84 and extends downward and forward from the wall 100 toward the bottom 80 (right side as viewed in FIG. 1) And further includes a plate extending between the side walls 86, the recyclable material pushed rearward by the ram 72a is lifted above the drop floor assembly 94. As shown in FIG.

The middle partition wall 90 extends rearwardly from the front wall 82 downwardly from the roof 84 to divide the top and front portions of the storage space 96 into left and right halves. The middle partition wall 90, the movable partition 92a and 92b and the drop floor assembly 94a and 94b are configured to divide the storage space 96 into three separate compartments (an upper right compartment 107a, The compartment 107b, the center compartment 107c, see Fig. 2). Eventually, each compartment is used to separate and contain different recyclable materials. The dividing wall 90 is preferably positioned to mate with the middle chute wall 58 between the openings 66a and 98a and the openings 66b and 98b. The dividing wall 90 includes position adjustment lowering zones 106, The positioning adjuster 106 extends completely or at least partially through the dividing wall 90 at a location that is selectively spaced apart along the top edge of the dividing wall 90. The positioning adjuster 108 extends completely or at least partially into the dividing wall 90 at a position that is selectively spaced apart along the lowermost edge of the dividing wall 90. In a preferred embodiment, the alignment fixture 106 is 6 inches away from each other and the alignment fixture 108 is 6 inches away from each other. The spacing between the position adjustment lower zones 106 is offset by 3 inches from the interval of the position adjustment lower zones 108 such that each of the position adjustment lower zones 106 is spaced 3 inches Correspondingly, the positioning holes are provided in opposing positioning regulating recesses 106, 108 adjacent the side walls 86. As shown in FIG. As will be described in more detail below, the apertures in the side wall 86 and the locating recesses 106 and 108 are selectively positioned at various locations along the longitudinal length of the storage space 96 such that the movable partition 92a, 92b , The length thereof and the volume of the upper storage compartments 107a and 107b can be adjusted accordingly.

The movable partition 92a, 92b is located on both opposite sides of the dividing wall 90. The movable partition 92a is located on the right side of the partition wall 90 and the movable partition 92b is located on the left side of the partition wall 90. [ The movable partition 92a, 92b preferably comprises a rectangular tubular frame with a thin sheet of sheet steel welded in place in the frame, respectively. Alternatively, the partitions 92a and 92b may be made of a hard, high-strength plastic that is lighter than a thin steel plate. Each movable partition 92a, 92b further includes a position adjustment member 110 positioned at each of the four corners of the back side of the movable partition 92a, 92b. Positioning member 110 is sized and supported to engage corresponding positioning bores 106 and 108 in dividing wall 92 and similar positioning bores adjacent to side walls 86. As a result, each of the partitions 92a, 92b can be positioned forward and rearward to reduce or increase the material receiving volume of the compartments 107a, 107b. Because the zones 106 and 108 are provided in the dividing wall 90 and correspondingly arranged apertures are provided in the side walls 86, the dividing walls 92a and 92b are independently supported, 94a, 94b.

The drop floor assemblies 94a and 94b are preferably located on both opposite sides of the dividing wall 90 and include horizontal bulkheads 120a and 120b (see FIG. 2), hinges 122a and 122b A cross tube 124 for supporting a hook latch, and hook latches 126a and 126b. Each of the floor panels 120a and 120b is a rectangular thin plate made of thin steel plate which functions as a floor for the compartments 107a and 107b. Alternatively, the bottom panels 120a and 120b may be formed of a hard, high-strength plastic that is lighter than a thin steel plate. The floor panels 120a, 120b include opposite side edges 127, 128, respectively. The edge 127 of each panel 120a and 120b is preferably tubular and is pivotally coupled to the front wall 82 by respective hinges 122a and 122b.

The edge 128 of each panel 120a and 120b is positioned at the opposite edge 127 and pivots between the raised position 129 and the lowered position 130 (shown in phantom). In the raised position 129, the edge portion 128 of one or both of the floor panels 122a and 122b is detachably supported by the hook latch support cross tube 124 and the hook latches 126a and 126b. The hinges 122a and 122b (see FIG. 2) extend through and extend through the edge 127 of each floor panel 120a and 120b. The hinges 122a and 122b allow the floor panels 120a and 120b to be moved or pivoted in a vertical direction for the purpose of increasing the volume of each compartment 107a and 107b communicating with the discharge opening 106. [ In an embodiment in which the storage structure 18 has a curved or outwardly curved side wall 86, the hinges 122a and 122b are spaced from each other at the center so that the bottom panels 120a and 120b fall to the bottom 80 with a suitable clearance. It is preferable to be inclined downward. Thus, the bottom panels 120a, 120b are also inclined slightly downward from the center of the storage structure 18. In addition, since the floor panels 120a and 120b can move in the vertical direction, the positionally adjusted movable partition 92a and 92b can be held in place and the recyclable material can be discharged from the compartments 107a and 107b There is no need to remove it or move it. The volume of the compartments 107a and 107b communicating with the discharge opening 106 can be increased so that the waste and the recyclable material in the compartments 107a and 107b are easier to compact and unload. Since the final flow path between the upper and lower compartments is not narrow, the (recyclable) material is not further compressed when it falls into the lower compartment. Further, since the entire floor can be moved in the vertical direction and extended to some extent, the horizontal or corner portion to prevent the recyclable material from falling off into the lower compartment as well as to prevent the recyclable material from being completely unloaded out of the upper compartment does not exist. As can be appreciated, other drive mechanisms may also be provided for vertical raising and lowering of the floor panels 120a, 120b. For example, the floor panels 120a, 120b may be raised and lowered mechanically, hydraulically, or pneumatically, either by centering the hinges 122a, 122b or by raising and lowering the floor panels 120a, So that both opposing sides of the bottom panels 120a and 120b are lowered while being guided in the channel or groove provided in the side wall 86 and the partition wall 90. [ Further, the positions of the hinges 122a and 122b can be changed. For example, the bottom panels 120a and 120b may be hingedly coupled to their sidewalls 86 so that they fall or fall in a position adjacent to the side wall 86 and in a side-by-side position.

The hook latch support cross tube 124 extends between the side walls 86 and provides a support structure for supporting the hook latches 126a and 126b and ultimately the edge 128 of the bottom panels 120a and 120b do.

The hook latches 126a and 126b (see FIG. 2) are pivotally coupled to the lower end of the supporting cross tube 124. Each hook latch 126a, 126b has one or more latches or hooks 132 that engage the tubular ends of the bottom panels 120a, 120b. The hook 132 supports the floor panels 120a and 120b in the raised position such that the compartments 107a and 107b are separated from the compartment 107c. Once the compartment 107c is emptied, the hook 132 can be rotated (clockwise in FIG. 4) to release one or both of the floor panels 120a, 120b so that the disengaged floor panels 120a, 120b ) Is caused to fall to the lowered position 130 (shown in phantom in FIG. 1) by gravity action to unload the recyclable material from the compartment.

During the unloading of material from the storage structure 18 and the compactor 16, the front end of the storage structure 18 is raised for the purpose of tilting the storage structure 18. As a result, the tubular end 128 of one or both of the floor panels 120a, 120b pivots about the hinges 122a, 122b and faces the hook 132 at a distance from the bottom 80. The tubular end 128 of one or both of the floor panels 120a and 120b may be self-positioned adjacent to the hook 132 by gravity action when the storage structure 18 is tilted to a vertical or substantially vertical position . Thus, the positioned floor panels 120a, 120b require only the counterclockwise rotation so that the hook 132 can be recombined with the tubular end 130 of the floor panels 120a, 120b. Once the storage structure 18 has been lowered to its normal horizontal position, the hook 132 will again support the floor panels 120a, 120b. Therefore, there is no need for a space-consuming and expensive hydraulic-operated lifting drive mechanism for moving the floor panels 120a, 120b in the raised position.

2, the compartments 34a, 34b and 34c of the stacker 14 are connected to the compartment chute (not shown) when the stacker 14 is lifted by the lifting device 15 above the presser 16, 64a, 64b, 64c, respectively. The arms or forks 40a and 40b are pivotally connected or hingedly coupled to the press 16 by lugs 150 and bolts 152 at the first ends of the forks 40a and 40b. The second ends of the opposed forks 40a and 40b are spaced apart from each other to be engaged with the lifting lugs 32a and 32b of the stacking cylinder 14. [ The elevating device 15 is hydraulically operated such that the loading cylinder 14 is lifted above the presser 16 to empty the recyclable material into the presser 16. [

As best shown in FIG. 2, each of the upper presser shots 64a, 64b is open into the upper compartments 107a, 107b through openings 68a, 98a and openings 68b, 98b. The rams 72a and 72b thus pressurize the recyclable material discarded into the compartments 107a and 107b of the storage structure 18 through the chutes 76a and 76b from the compartments 30a and 30b in the stacker 14 Or squeezed.

3 and 4, the movable partition 92a, 92b and the drop floor assembly 94a, 94b are shown in more detail. As shown in FIG. 3, the sidewalls 86 have holes or low zones 156, 158. The lower zones 156 and 158 are configured to allow the movable partition 92a and 92b to move between the side walls 86 and the dividing wall 90 for the purpose of adjusting the volume of each of the two upper compartments, 108 of the dividing wall 90 so as to be firmly but detachably bolted to the position adjusting member 110 at the selected position.

The position adjusting member 110 is positioned at each of the four corners of the movable partition 92a and 92b and has a guide portion 160 and a position adjusting bolt 162. [ The guide portion 160 is preferably a cylindrical tube fixedly mounted on each of the four corners of each movable partition 92a, 92b. Each of the guide portions 160 has an inner diameter that mates with the adjacent low region and is sized to accommodate and support the position adjusting bolt 162. Since the position adjusting bolt 162 is slidably accommodated in the guide portion 160, one end of each bolt 162 is engaged with the low-lying region that fixes the movable partition. At the same time, the bolt 162 can retract from the lower region, which moves the movable partition 92a, 92b. As can be appreciated, the positioning bolt 162 may also be threadably received within the guide 160 and may be biased elastically in engagement with the corresponding stop. In addition, the interconnects or cables may be used to position the positioning members 110 adjacent the walls 90, 86 to allow for easy adjustment of the partitions 92a, 92b while manually actuating both positioning members 110. [ As shown in FIG.

As shown again in FIG. 3, the hook latches 126a, 126b include a guide tube 164, a latch shaft 166, a lever arm 168, a lever guide, and a locking portion 170. The guide tube 164 is firmly fixed to the lower end of the latch support tube 124. The guide tube 164 receives and guides the rotation of the latch shaft 166. The latch shaft 166 is a elongated cylindrical rod that supports a hook 132 that extends and rotates through the guide tube 164 and locks and releases the end 128 of the floor panel 120. The latch shaft 166 preferably protrudes from the guide tube 164 at both ends of the guide tube 164. Each end of the latch shaft 166 protruding outward from the guide tube 164 supports the hook 132. Thus, each latch shaft 166 supports two hooks 132 that engage the edge 128 of the bottom panel 120. As can be appreciated, the guide tube 164 and the latch shaft 166 can be deformed to support and support a predetermined number of hooks 132. The latch shaft 166 extends through the side wall 86 and is connected to the lever arm 168.

The lever arm 168 has a first end fixed to the latch shaft 166 and a second opposing end coupled within the lever guide and the locking portion 170. The lever arm 168 may be mounted to either one or both of the floor panels 120a and 120b in an elevated position as shown or to release one or both of the floor panels 120a and 120b as shown in phantom, The hook 166 and the hook 132 can be manually rotated to the outer side of the side wall 86. [ Alternatively, a hydraulic, pneumatic, or known power drive mechanism may be used to rotate the hook 132 and the latch shaft 166 that locks and releases the floor panels 120a, 120b.

The lever guide and locking portions 170a and 170b are shown in detail in FIG. 5 and generally form a track for moving and guiding the lever arm 158. The locking portions 160a and 160b further include a locking mechanism (not shown) that locks the lever arm 168 to a locked position and the hook 132 also locks the hook 132 to the floor panel 120 It is locked in the selected position to prevent rotation and sudden release.

4 is a partially enlarged cross-sectional view of the drop floor assembly 94b and the movable partition 92b. 4, the movable partition 92a (not shown) and the movable partition 92b include a plate 174 for supporting the guide portion 160 and the position adjusting bolt 162, And a rectangular frame 172 that is formed by tubularizing the inside of the metal. The plate 174 is preferably formed of 11 standard steel plates and welded to the edge of the rectangular frame 172. The frame 172 provides a rigid structure for supporting the plate 174 containing the waste and recyclable material in the compartments 107a, 107b. As described above, the position adjusting bolt 162 is supported and guided by the guide portion 160. [ The bolt 162 extends through the frame 172 and is engaged with the alignment slots 106 and 108 of the dividing wall 90 as well as the alignment holes 156 and 158 in the side wall 86 (See also Fig. The position adjusting bolt 162 can be separated from the position adjusting lowering portions 106, 108, 156, 158 and recombined in the adjacent position adjusting holes to move the movable partition. The movable partitions 92a and 92b can thus be routed to the roof 90 such that the partition 92 can be guided longitudinally between the side wall 86 and the wall 90, 84 and the floor panel 120 at regular intervals.

FIG. 4 also shows the drop floor assembly 94b in greater detail. As best shown in FIG. 4, the guide tube 164 is preferably welded to the lower surface of the cross tube 124 for supporting the hook latch. The guide tube 164 is a hollow tubular member having an inner diameter sized to accommodate and guide the latch shaft 166. The latch shaft 166 is rotatably disposed within the guide tube 164 so that the latch shaft 166 is ultimately supported by the support cross tube 124. The portion of the latch shaft 166 extends outwardly from the guide tube 164 and supports the hook 132. The hook 132 is coupled to the edge 128 of the floor panel 120 releasably supporting the floor panel 120 in a generally horizontal direction below the movable partition 92. To rotate the hook 132 so that the engagement between the edge 128 of the bottom panel 120b and the hook 132 is released, as shown by the dashed line 179, the latch shaft 166 engages the guide tube < RTI ID = (164). Therefore, the bottom panel 120b is released and dropped by gravity. Once the recyclable material is unloaded from the compartment 107b, the bottom panel 120b can be hooked back to its original position by the hook 132. [

5 is a side perspective view of a portion of the storage structure 18 showing the lever guide and locking portion 170. FIG. Since the lever guide portion and the lock portion 170b are the same as the lever guide portion and the lock portion 170a, only one of the lever guide portion and the lock portion 170a is illustrated in detail for the purpose of illustration. The lever guide and lock portion 170a includes a protector 180, an instant release pin 182, an angle bracket 184, and a spring 186. [ The protective portion 180 is a pair of elongated bars that are substantially flat and spaced apart from one another and are rigidly connected to the side walls 86 at their ends. The protector 180 provides a channel or track for guiding the movement of the lever arm 168 between the protector 180 and the side wall 86. The protector 180 is preferably secured to the side wall 86 to partially surround the lower end of the lever arm 168. The protector 180 also defines a pair of mating holes 188 that extend through the spaced-apart bar forming the protector 180. The hole 188 is sized to accommodate the instant release pin 182. The instant release pin 182 is already known and housed in an aperture 188 that prevents the lever arm 168 from moving within the track formed by the guard 180. As a result, the hook 132 of the hook latch 126a is also fixed in place and can not be rotated. By releasing the release pin 188 by hand, the movement of the lever arm 168 and the rotation of the hook 132 are performed to release the floor panel 120a.

Angle bracket 184 is fixedly secured to side wall 86. And the first end of spring 186 is pierced. The second end of the spring 186 is connected to the lever arm 168. The hook 132 is coupled to the bottom panel 120a (not shown) as the spring 186 deflects the lever arm 168 to the first position. As a result, the biasing force of the spring 186 and the release pin 188 prevents the bottom panel 120a from being unexpectedly released. At the same time, by disengaging the release pin 188, the lever arm 168 is moved in a direction repelling the biasing force of the spring 186 to release the floor panel 120a (not shown).

FIG. 6 illustrates adjusting or moving the partition 92 longitudinally between the front and rear of the storage structure 18 to adjust the volume of the compartments 107a, 107b. For ease of illustration, FIG. 6 shows that the movable partition 92 for volume control of the compartment 107b is moved. As can be appreciated, moving the movable partition 92 to adjust the volume of the compartment 107a is also accomplished similarly. As shown in FIG. 6, the rows of the low region 156 and the low region 158 of the side wall 86 are located between any of the rows 156 and 158, Are offset from each other by 1/2 distance. Each lower zone 156 is spaced about 6 inches from the adjacent lower zone 156 and each lower zone 158 is spaced from the adjacent lower zone 158 by about 6 inches The gap is off. Thus, the rows of low zones 156 and 158 are offset by about three inches relative to each other, such that each low zone 158 is positioned between adjacent low zones 156. The heat of the low region 156 extends longitudinally just below the roof 84. The heat of the low region 158 extends longitudinally upward just above the horizontal position of the bottom panel 120b. The movable partition 92b has an uppermost edge spaced a certain distance from the roof 84 and a lowest edge spaced a certain distance above the floor panel 120b so that the movable partition 92b has the same dimensions as shown in Figure 6 And can be pivoted about the low earth 156, 158 as well.

As shown by the dotted line, the movable partition 92b increases the volume of the compartment 107b by turning the lower end of the partition 92b about the lower region 156A as indicated by arrow A So as to be moved. The position adjustment bolt 162 adjacent to the lower end of the movable partition 92b is positioned to engage the lower section 158B and the position adjustment bolt 162 adjacent to the upper end of the movable partition 92b is positioned at the upper end The engagement with the lower region 156a is released and pivoted as shown by the arrow B so that it can be pivoted about the low region 158B. This process can be repeated when it is necessary to move the movable partition 92b to a predetermined position and also to selectively adjust the volume of the compartment 107b. The movable partition 92b is manually moved without using a complicated guide mechanism or alignment mechanism. Accordingly, the partition 92b can be easily moved without being stopped or pierced in the guide structure. Further, since the tolerance problem for the partition 92b is eliminated, the manufacturing cost is reduced.

7 and 8 illustrate another embodiment (vehicle 200) of the garbage collection vehicle 10 shown in Figs. 1 to 6; Figs. 7 and 8 show the garbage collection vehicle 10 with two compartments (200). FIG. 7 is a side sectional view of the vehicle 200, while FIG. 8 is a plan sectional view of the vehicle 200. Corresponds to the elements of the garbage collection vehicle 10, and elements of the same collection vehicle 200 are indicated by like numerals. The garbage collection vehicle 200 is configured such that the stacker 14 is replaced by a stacker 214 and the presser 16 is replaced with a presser 216 and the storage structure 18 is replaced with a storage structure 218 Otherwise, it is similar to the garbage collection vehicle 10. The loading cylinder 214 is similar to the loading cylinder 14 except that the partition wall 29 of the loading cylinder 214 is not provided. As a result, the dividing wall 26 divides the stacking compartment 214 having an internal volume into the front compartment 234a and the rear compartment 234c. Each compartment can be used to contain recyclable materials and waste to be separated. As can be appreciated, the loading barrel 214 can also have a plurality of different configurations for containing various different recyclable materials requiring separation. As shown by the dotted line 236, the loading cylinder 214 is raised to the elevating device 15 and emptied into the press 216.

The compactor 216 is similar to the compactor 16 of the garbage collector vehicle 10 except that it has no walls 58 and thus only includes two separate chutes 264 and 264. The ram assemblies 60a and 60b of the garbage collection vehicle 10 are replaced by the ram assemblies 260 and the openings 66a and 66b and the openings 68a and 68b are replaced with openings 266 and 268, respectively . The opening 266 extends between the opposing side walls 86 (see FIG. 8). Similarly, opening 268 extends between opposing side walls 86 near the lower end of chute 264a. The ram assembly 260 is similar to the ram assembly 60a except that the ram assembly 260a extends between the opposing side walls 86 as shown in FIG. As a result, the opening 266 and the chute 264 provide a large area through which the material can be unloaded from the compartment 234a of the stacker 214 into the presser 16. The recyclable material is then pushed through the opening 268a into the upper end of the storage structure 218 and squeezed. Chute 64c receives recyclable material from compartment 234c. The ram assembly 60c pushes the material into the storage structure 218 through the opening 68c and compresses it.

The storage structure 218 is similar to the storage structure 18 except that it includes a single opening 298 instead of the side openings 98a and 98b of the storage structure 218. [ The storage structure 218 also differs from the storage structure 18 in that it does not include a partition wall 90 and includes a single movable partition 292 and a single drop floor assembly 294.

The openings 298 extend substantially between the side walls 86 across the storage structure 218 and communicate with the openings 268 of the compactor 216. The opening 298 is preferably located above the drop floor assembly 294 so that the press 260 presses the (waste) material onto the drop floor assembly 294 through the openings 268, 298.

The movable partition 292 is similar to the movable partition 92a, 92b except that it extends substantially between the side walls 86 across the storage structure 218. The positioning member 110 of the movable partition 292 is coupled to the opposing side wall 86 of the storage structure 218 such that the movable partition 292 can be releasably positioned along the storage structure 218. As shown in FIG. 6, the movable partition 292 is adjustable or movable between the forward and rearward directions of the storage structure 218, similar to the adjustment of the movable partition 92a, 92b. Thus, the movable partition 292 allows the volume of the upper compartment 207 to be adjusted to accommodate various amounts of waste and recyclable material.

The drop floor assembly 294 is similar to drop floor assemblies 94a and 94b except that it includes a single floor panel 320, a single hinge 322 and a single hook latch 326. The floor panel 320 is similar to the floor panels 120a and 120b except that it extends substantially between the side walls 86 to provide a single intermediate floor. The hinge 322 is similar to the hinges 122a and 122b except that it extends substantially between the side walls 86. [ Similarly, the hook latch 326 is similar to the hook latches 126a, 126b except that it extends substantially between the sidewalls 86. As shown in Fig. The hook latch 326 preferably includes four hooks instead of two hooks to more rigidly support the bottom panel 320. The hook latch 326 includes two lever arms 168 and two lever guides and a locking portion 170. Each of the lever arms 168 and the lever guide portion and the locking portion 170 are opposed to each other And extends through the side wall 86. As a result, the hook latch 326 can be manually actuated to lock or unlock the floor panel 320 from each side of the storage structure 218. The storage structure 218 allows the volume of the compartments 107c and 207 to be adjusted by moving the movable partition 292 forward or backward. Similar to the storage structure 18, the storage structure 218 allows the bottom panel to be released to increase the volume of the compartment 207 communicating with the discharge opening 106. Therefore, the waste and the recyclable material in the compartment 207 are less compressed and easier to unload. In addition, since the floor panel 320 can move in the vertical direction, the moveable partition 292 once positioned is held in place, requiring that the recyclable material be lifted or moved to eject from the compartment 207 . For drop floor assemblies 94A and 94B drop floor assembly 294 may be lifted or lowered under gravity action and may only be raised by tilting or lifting storage structure 218 to engage hook latch 326 . Alternatively, the floor panel 320 may be raised and lowered mechanically and hydraulically about the hinge 322. In addition, the position of the hinge 322 may be varied. By way of example, the bottom panel 320 may be hingedly coupled to the side wall 86 to fall to a position adjacent to the side wall 86 in a side-by-side manner. Instead of the hinges 322, the storage structure 218 may be provided with channels or grooves so that both opposite sides of the bottom panel 320 can be lowered while being guided in the channels or grooves.

FIG. 9 shows another preferred embodiment (stacker 314 and presser 316) of the presser 14 and the presser 16 shown in FIGS. 1-8. This stacking cylinder 314 is connected to the stacking cylinder 14 except that the stacking cylinder 314 includes two dividing walls 328 and 329 which form three compartments 334a, 334b and 334c, . Each compartment 334 is fabricated and designed to accommodate waste and recyclable materials that must be sorted. Preferably, the compartment 334c for accommodating conventional non-recyclable waste occupies a substantial portion of the stacking bin 314. [ The compartments 334a and 334b divide the remainder of the stacker 314 to house paper and glass or plastic material, respectively.

The presser 316 is similar to the presser 16 except that the presser 316 includes the bottom 356 and 357 of the upper chute and the walls 358 and 359 of the intermediate chute. The bottoms 356 and 357 of the chute extend rearward from the front of the presser 316 along the side presser 316. Each of the walls 358 and 359 of the chute extends vertically between the roofs of the presser 316 to the bottoms 356 and 357. The bottoms 356 and 357 and the walls 358 and 359 divide the compactor 316 into three chutes which are arranged side by side, namely an upper right chute 360a, an upper left chute 360b and a lower center chute 360c do. Each of the suites 360a, 360b, and 360c is preferably in registration with the compartments 334a, 334b, and 334c of the stacker 314. As a result, the separated garbage in the compartments 334 of the stacker 314 can be emptied into the separation chute 360 of the presser 316 without intermixing the materials. Similar to the press 16, the material in the chute 360a, 360b, 360c is squeezed in the compartments 107a, 107b, 107c of the storage structure 18.

FIG. 10 shows another embodiment (drop floor assembly 394b) of the drop floor assembly 94b shown in FIG. For ease of illustration, the elements of the same drop floor assembly 394b as those of the drop floor assembly 94b are identified by the same reference numerals. The drop floor assembly 394b includes a floor panel 320b and a hook latch 326b. The bottom panel 320b is similar to the bottom panel 120b except that the edge 128 of the bottom panel 320b includes a lip member 321. [ The lip member 321 preferably includes a steel bar welded to the lower end of the edge 128. The lip 321 protrudes from the edge 128 to engage the hook latch 326b.

The hook latch 326b is similar to the hook latch 166b except that the hook latch 326b includes a cover plate 327, a guide tube 364, a latch shaft 366, and a hook 332 Do. The cover plate 327 is preferably a flat steel bar welded to the support tube 124 so as to protrude horizontally from the support tube 124 toward the bottom panel 320b. The cover plate 327 extends at a substantially horizontal level substantially the same as the top surface of the bottom panel 320b with a tolerance close to the bottom panel 320b. The cover plate 327 supports the guide tube 364, the latch shaft 366, and the hook 332. This cover plate 327 prevents material or trash from accumulating and accumulating on the hook 332 and obstructs the function of the hook latch 326b if the material or the trash accumulates and accumulates on the hook. At the same time, the cover plate 327 does not prevent material from moving across the tube 124 onto the bottom panel 32Ob when the movable partition slides forward.

The guide tube 364 is similar to the guide tube 164 shown in FIG. The guide tube 364 is fixedly coupled to the lower surface of the cover plate 327. The guide tube 364 supports the latch shaft 366 and guides the rotation of the latch shaft 366. The latch shaft 366 is similar to the latch shaft 166 shown in FIG. The latch shaft 366 extends through the guide tube 364 to rotatably support the hook 332.

Each hook 332 typically includes an L-shaped member having a substantially vertical portion 333 and a substantially horizontal portion 334. The vertical portion 333 is mounted to the latch shaft 366 while the horizontal portion 334 extends horizontally from the vertical portion 333 toward the bottom panel 320b. The horizontal portion 334 has a predetermined width to engage the lip member 321 of the bottom panel 320b. As a result, the rotation of the latch shaft 366 may cause the bottom panel 320b to move up and down with the rib 321 of the bottom panel 320b to support the bottom panel 320b in the raised position, Thereby rotating the horizontal portion 334 of each hook 332. Further, since the hook 332 is formed into the L-shaped member, the hook 332 is more easily engaged with the bottom panel 320b.

Figures 11-14 schematically illustrate another embodiment of the storage structure 18. For ease of illustration, like reference numerals are used to denote like elements in FIGS. 11-14. 11 shows a schematic view of the storage structure 418 which is mounted on a frame adjacent to the press and includes a bottom 480, a front wall 482, a roof 484, a back door assembly 488, Assembly 494 as shown in FIG. The bottom 480, the front wall 482, the roof 484, the side walls 486 and the back door assembly 488 form an internal storage space 496. The front wall 482 includes openings 498a and 498b. These openings 498a and 498b are arranged to receive waste and recycled materials from a compactor (not shown). The rear door assembly 488 encloses the rear portion of the internal storage space 496 for the purpose of retaining the waste and recycled material in the internal storage space 496. The rear door assembly 488 also forms a discharge opening 506 through which material can be evacuated from the internal storage space 496. The drop floor assembly 494 includes a front panel 520, a hinge 522, and a lift driving mechanism 526. The bottom panel 496 extends from the front wall 482 to the rear wall or back door assembly 488 between the side walls 486. The floor panel 520 divides the internal storage space 496 into an upper compartment 507a and a lower compartment 507b. The floor panel 520 has opposite side edges 527, 528 and opposite side edges 554, 556. The opposite edge 527 is preferably hingedly coupled to the front wall 482 by a hinge 522. The opposite edge portions 528 are preferably coupled to the elevation drive mechanism 526.

The elevation drive mechanism 526 is preferably a hydraulic or pneumatic piston cylinder assembly and includes cylinder assemblies 550a and 550b and pistons 552a and 552b. The cylinder assemblies 550a and 550b are coupled to the side wall 486. [ The pistons 552a and 552b extend from the cylinder assemblies 550a and 550b and are coupled to the edges 554 and 556 of the bottom panel 494 near the edge 528, respectively. When the piston 552 is actuated, the floor panel 494 rises and falls to reduce or increase the volume of the compartment 507a communicating with the discharge opening 506. As a result, the waste and materials in the compartment 507 are less compressed and easier to unload. Also, since the bottom panel 494 extends from the wall 482 to the rear wall or back door assembly 488, the compartment 507a has a larger volume for containing the selected material. As can be appreciated, the lifting drive mechanism 526 may have a hook latch, as shown in Figures 1 and 2.

12 is a schematic view of the storage structure 618 that is designed to be mounted on a frame adjacent to the press and includes a bottom 680, a front wall 682, a roof 684, side walls 686, An intermediate partition wall 690, and drop floor assemblies 692a and 692b. The bottom 680, the front wall 682, the roof 684, the side walls 686 and the back door assembly 688 form the internal storage space 696 of the storage structure 618. The front wall 682 includes an opening 698a, an opening 698b, and a lower opening 698c. The openings 698a, 698b and 698c communicate with a compacting device (not shown) so that the storage structure 618 can receive the waste and recycled material through the openings 698. Preferably, The assembly (not shown) is matched with the opening in the presser so that the waste and recyclable material can be pushed into the internal storage space 696 through the opening 698. [ The rear door assembly 688 serves as a rear wall for enclosing the rear portion of the internal storage space 696 for retaining the waste and recyclable material in the storage structure 618. Preferably, the rear door assembly 688 is openable to form a discharge opening 706 through which material may be emptied from the internal storage space 696.

The intermediate partition wall 690 extends rearward from the front wall 682 downward from the roof 684 and divides the upper portion of the storage space 696 into left and right halves. The partition wall 690 is preferably formed with a discharge opening 706 extending from the front wall 682 to the rear door assembly 688. The intermediate wall 690 and the drop floor assembly 694a and 694b divides the storage space 696 into three separate compartments 707a, 707b and 707c. As a result, each compartment can be used to separate and contain different materials. The dividing wall 690 is preferably positioned between the opening 698a and the opening 698b.

Drop floor assemblies 692a and 692b are preferably located opposite partition wall 690 and include floor panels 720a and 720b, sites 722a and 722b, and elevation drive mechanisms 726a and 726b . The bottom panels 720a and 720b and the hinges 720b and 720b are substantially the same except that the bottom panels 720a and 720b substantially extend from the front wall 682 toward the rear door assembly 688 along the entire length of the storage structure 618 722a and 722b are similar to the bottom panels 120a and 120b and the hinges 122a and 122b of the storage structure 18. Thus, the compartments 707a, 707b are larger and can contain a greater amount of waste and recyclable material. The bottom panels 720a and 720b have opposite edges 727 and 728 and opposite edges 754 and 756. The opposite side edges 727 of each bottom panel 720a and 720b are preferably hingedly coupled to the front wall 682 by hinges 722a and 722b. The opposite edge portions 728 of the respective floor panels 720a and 720b are coupled to the elevation driving mechanisms 726a and 726b. As a result, in order to increase the volume of the compartments 707a, 707b communicating with the discharge opening 706, the floor panels 720a, 720b are pivoted about the localities 722a, 722b to be vertically movable .

The elevation drive mechanisms 726a and 726b are preferably hydraulic or pneumatic piston cylinder assemblies including cylinders 750a and 750b and pistons 752a and 752b. It is preferred that the cylinders 750a and 750b are coupled to the side wall 686 while the pistons 752a and 752b are coupled to the edge 756 near the edge 728. [ When the piston 752 is selectively operated, the floor panels 720a and 720b can be raised and lowered. As can be appreciated, the lifting drive mechanisms 726a, 726b may also include a hook latch 126 of the storage structure 18. The volume of the compartments 707a, 707b communicating with the discharge opening 706 can be increased, so that the waste and recyclable materials in the compartments 707a, 707b are less pressed and easier to unload. The storage structure 618 provides three separate compartments, where the upper compartment has a greater capacity for storing the trash properly.

FIG. 13 schematically shows another embodiment (storage structure 818) of the storage structure 618 shown in FIG. 12. For ease of illustration, elements of the same storage structure 618 as the corresponding elements of the storage structure 618 are indicated with like reference numerals. The storage structure 818 is similar to the storage structure 618 except that the storage structure 818 includes a drop floor assembly 892a, 892b in place of each of the drop floor assemblies 692a, 692b. Drop floor assemblies 892a and 892b are preferably located on opposite sides of the dividing wall 690 and include bottom panels 920a and 920b, hinges 922a and 922b, and elevation drive mechanisms 926a and 926b . The bottom panels 920a and 920b include opposite side edges 927 and 928 and opposite side edges 954 and 956. The edge 954 of each panel 920a, 920b is pivotally coupled to the intermediate wall 690 by hinges 922a, 922b, respectively. The edge 956 of each floor panel 920a, 920b is located at the opposite edge 954 and pivots between the raised position and the lowered position. As shown in FIG. 13, the floor panel 920a is in the raised position, while the floor panel 920b is in the lowered position. In the raised position, the bottom panels 920a, 920b and the intermediate wall 690 divide the internal storage space 996 into three separate compartments 907a, 907b, 907c. When the both floor panels 920a and 920b are lowered, the internal storage space 896 is divided into two compartments, a left compartment and a right compartment. Thus, the storage structure 818 may be used to provide both three compartment storage structures or two compartment storage structures. Also, since the bottom panels 920a and 920b are all adjustable in the vertical direction, the volume of the compartments 907a and 907b communicating with the discharge opening 706 is less than the volume of waste and recyclable material in the compartment, Can be augmented more easily. Because the floor panels 920a and 920b extend substantially from the front wall 682 toward the rear door assembly 688 along the entire length of the storage structure 818, the capacity or volume of the compartments 907a and 907b is large It is large enough to accommodate garbage or recyclable materials.

The elevation drive mechanisms 926a and 926b are the same as the elevation drive mechanisms 926a and 926b shown in FIG. 12 and include cylinder assemblies 950a and 950b and pistons 952a and 952b therein. Each cylinder assembly 950a, 950b is preferably coupled to the sidewall 682. Alternatively, the cylinder assemblies 950a, 950b may be coupled to the side walls 696. [ Each piston 952 extends from the cylinder assembly 850 and has one end coupled to the edge 956 near the edge 928 of the bottom panel 920a, 920b. When the piston 952 is actuated by hydraulic or pneumatic pressure, the floor panels 920a and 920b rise and fall as needed. Further, the lifting drive mechanisms 926a and 926b may include hook latches 126a and 126b, as shown in FIGS.

FIG. 14 schematically shows another embodiment (storage structure 1018) of the storage structure 618 shown in FIG. 12. For ease of illustration, elements of the storage structure 1018 that are identical to the elements of the storage structure 618 are labeled with like numerals. The storage structure 1018 is similar to the storage structure 618 except that the storage structure 1018 includes drop floor assemblies 1092a and 1092b in place of each of the drop floor assemblies 692a and 692b. Drop floor assemblies 1092a and 1092b include floor panels 1120a and 1120b, hinges 1122a and 1122b, and hook latches 1126a and 1126b. Each of the floor panels 112Oa and 112Ob includes opposite side edges 1127 and 1128 and opposite side edges 1154 and 1156. [ The edge 1154 of each floor panel 1120a, 1120b is pivotally coupled to the side wall 686 by hinges 1122a, 1122b. As a result, the edge portion 1156 can be raised and lowered. In the raised position, the floor panels 1120a, 1120b divide the internal storage space 1096 into three compartments 1107a, 1107b, 1107c. In the lowered position, edge 1156 is positioned adjacent sidewall 686. Thus, when both the bottom panels 1120a and 1120b are in the lowered position, the internal storage space 1096 is a single, unpartitioned compartment. It is also preferred that each of the bottom panels 1120a and 1120b has a width between the edges 1154 and 1156 that is less than or equal to the height at which the bottom panels 1120a and 1120b are pivotally coupled to the side walls 686, The housing 1156 can pivot and contact against the side wall 686 and does not substantially protrude into the compartment 1107c for the purpose of preventing loading or squeezing of material in the compartment 1107c. Also, lowering one or both of the floor panels 1127a, 1127b increases the volume of one or both compartments 1107a, 1107b communicating with the discharge opening 706. [ For example, by lowering the floor panel 1120b (as shown in FIG. 12), the garbage and recyclable material squeezed into the compartment 1107b fall into the compartment 1107c and are compressed less. Therefore, unloading becomes easier.

Hook latches 1126a and 1126b are similar to hook latches 126a and 126b shown in Figures 1 to 6 except that it extends between rear door assembly 688 and front wall 682 adjacent to dividing wall 690. [ . Preferably, each hook latch 1126a, 1126b is coupled to the lower end of the dividing wall 690. [ Similar to hook latch 126, hook latches 1126a and 1126b are releasably coupled to edge portions 1156 of bottom panels 1120a and 1120b, respectively, to hold bottom panels 1120a and 1120b in an elevated position And a hook 1132. The hook 1132 is rotated by a lever arm (not shown) to release the edge 1156 of the bottom panels 1120a and 1120b so that the bottom panel 1120b is moved to the lowered position shown in the lowered position in FIG. 12 The floor panels 1120a and 1120b can be easily rotated back to the raised position and the hook latches 1126a, 1126b may be rotated again to detachably secure the floor panel in the raised position.

In conclusion, the multi-compartment storage structure of the present invention provides a plurality of compartments for containing recyclable materials and trashes that need to be separated. As each compartment is increased or decreased in volume, it is possible to provide compartments of various capacities for containing waste and recyclable materials. Since the movable partition is independently supported from the bottom of the upper compartment, its bottom can move in the vertical direction, and the movable partition does not require a complicated structure for guiding and positioning. Since the bottom of the upper compartment can be raised and lowered in the vertical direction, the volume of the upper compartment communicating with the discharge opening can be increased so as not to squeeze the material contained in the upper compartment. Also, since the bottom of the upper compartment can move in its own vertical direction, the partition that is movable between the compartment and the discharge opening need not be moved or moved for purposes of unloading. Therefore, it is easier to unload garbage and recyclable materials from the storage structure of the present invention. The bottom of the upper compartment is preferably hingedly coupled to one end of the storage structure and is releasably supported at the raised position so that the bottom can be easily raised and lowered using gravity. Therefore, there is no need for a lifting drive mechanism that is expensive and occupies a space. In summary, the storage structure of the present invention makes it easier to collect, transport and discharge waste and recyclable materials.

Although the present invention has been described with reference to the preferred embodiments, those skilled in the art will recognize that the forms and details may be modified without departing from the spirit and scope of the present invention.
