Modes for Carrying Out the Invention
Referring to FIGS. 1-2C and 5, shown therein and generally designated by the reference character 10 is a power operated container crushing device constructed in accordance with the following description. The device 10 includes an upper housing 12 and a lower housing 14. The upper housing 12 includes a crushing mechanism 20, a power source 16 to power the crushing mechanism, and a switching mechanism 18 functionally linked by electrical communication to the crushing mechanism 20 and the power source 16 for activating the crushing mechanism. As shown, the power source 16 is a rechargeable battery, however it is contemplated that the power source 16 could be a non-rechargeable battery, or the device could be plugged into a DC or AC power source.
Referring now to FIGS. 3A - 3D, lower housing 14 is integral with the upper housing 12, and includes a first opening 40 for inserting the container 42 therethrough, in this case an aluminum can. See FIGS. 4A - 4D, where the container 42 is a plastic bottle. But the operation is the same. The lower housing 12 may also include a second opening 41 to allow a crushed container 42 to pass through and exit from the lower housing 14. The second opening 41 is particularly effective when the device is placed in a horizontal position so that when a container 42 is crushed, it is now small enough to fall through the second opening and preferably into a recycling bin just below. See FIG. 8. A door 44 is hingedly attached thereto for gaining or preventing access to the lower housing 14 from the first opening 40. The door 44 may include a latch mechanism 46 for closing the door 44 and denting means for predenting the container
42 when the door 44 is latched. As shown, the denting means is a wedge shaped portion 48 integral with the door 44, which acts to slightly dent the container 42 when the door 44 is latched thereby weakening the container 42 and making it more easily crushable by the crushing mechanism 20. It should be appreciated that any type of shape that predents the container 42 would be equally effective. Further, the denting means could be on the wall opposite the door 44 and still be effective. In a particular embodiment, the switching mechanism 18 electronically linked to the latch mechanism 46 such that the switching mechanism is inoperable if the door 44 is not fully latched and/or the crushing mechanism 20 is deactivated if the door 44 is unlatched and opened during operation.
Referring again to FIGS. 1-2C and 5, the crushing mechanism 20 includes a motor 22 attached to and retained in the upper housing 12 by a bracket 24 and screws 25. The motor 22 includes a motor gear 26 for rotational engagement with a drive gear 27. The drive gear 27 is fixably attached to one end of a drive axle 28. The other end of the drive 28 axle includes means to attach the drive axle 28 to a threaded sleeve 29. As shown, the means to attach the drive axle 28 to the threaded sleeve 29 is a bore and screw assembly as is common in the art. Next, a threaded shaft 30 is threadably engaged to the threaded sleeve 29. Fixably attached using a screw and bore assembly to the lower end of the threaded shaft 30 is crushing plate 31. The crushing plate 31 is shaped to substantially fit the interior space of the lower housing 14, such that it is prevented from rotating within the lower housing. Thus, in contemplating the above described structure of the crushing mechanism 20, when the motor 22 rotates the
motor gear 26 in one direction, the crushing plate 31 moves in a downward direction into the lower housing 14 thereby crushing any container 42 inserted therein, and conversely, when the motor 22 rotates in the opposite direction, the crushing plate 31 moves in an upward direction. See below for more details regarding the operation of the device 10.
Additionally, the device 10 may include a first support plate 32 integral the upper housing 12, whereby the plate includes a bore 33 for said drive axle 28 to pass through. As shown, a bearing 34 is inserted into the bore 33 for rotational abutment to the drive axle 28. Further, a second support plate 35 is also shown integral with the lower portion of the upper housing 12, and includes a bore 33 for the threaded sleeve 29 to pass through. The first 32 and second 35 support plates provide the crushing mechanism 20 stability and help guide the crushing plate 31 in a vertical direction during operation.
The device 10 may also include reversing means electronically coupled to the crushing mechanism 20 for reversing the crushing plate 31 from a downward direction to an upward direction. Referring again to FIGS. 1-2C and 5, a first embodiment of the reversing means is shown. In this embodiment a pressure switch 36 is located on the crushing plate such that when the crushing plate extends to its lowest position (FIG. 2B), the switch 36 is activated by coming in contact with the base 37 of the lower housing thereby reversing the motor 22 and the direction of the crushing plate 31. Referring now to FIGS. 6 and 7, a second embodiment of the reversing means is shown. In this embodiment the reversing means is a torque sensor 38 such that when
a determined maximum torque is reached during the crushing of a container 42, the maximum torque is sensed by the sensor 38 thereby reversing the motor 22 and the direction of the crushing plate 31. Additional reversing means are also contemplated, for example: (1) the crushing mechanism 20 may reach its lowest point and pause for a determined amount of time before returning, and (2) the switching mechanism 18 can be used to control the direction of the motor 22 and respective crushing plate 31.
Referring to FIGS 3A - 4D, The basic operation of the device 10 is the following, a user opens the door 44 and inserts a container 42 into the first opening 40. The door is closed/latched which acts to both predent the container 42 and allows for the switching mechanism 18 to be operable. The user than depresses the switching mechanism 18 which activates the crushing mechanism 20 and causes the motor 22 to rotate the motor gear 26, which in turn causes the drive gear 27 and the drive axle 28 to rotate. This in turn causes the fixably attached threaded sleeve 29 to rotate. The threaded shaft 30 threadably engaged with the threaded sleeve 29 is prevented from rotating because of the crushing plate 31 abutting the interior surfaces of the lower housing 14. This allows the threaded shaft 30 to move in an upward or downward direction within the threaded sleeve 29, which allows the crushing plate 31 to complete the crushing process. As described above, the appropriate reversing means is activated and the crushing plate 31 reverses direction. Finally, if the device is situated horizontally as shown in FIG. 8, the crushed container 42 then passes through and exits from the lower housing 14 through the second opening 41 and into a recycling bin just below.
While the present disclosure has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this disclosure is not limited to the disclosed embodiments, but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
Industrial Applicability
The disclosed invention would be valuable to anyone that is conscious about recycling items such as aluminum cans and plastic bottles. The environmental benefits of recycling aluminum cans and plastic bottles are well accepted. One disadvantage of recycling is the large amount of space that such items take up in their uncrushed state. The power operated container crushing device described here is easy to use and solves the storage problem mentioned above.
