DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the invention is directed to a dumpster and portable toilet system, as illustrated at 10 in the figures. The dumpster and portable toilet system 10 generally includes a dumpster portion 12 and a portable toilet housing portion 14, as illustrated in FIGS. 1 and 2.
In some configurations, the dumpster portion 12 can be formed with a capacity of about 10 yards, 20 yards or 30 yards. The dumpster portion 12 includes side panels 20, a bottom panel 22, a front panel 24 and a rear panel 26, as illustrated in FIGS. 1-5.
The rear panel 26 may be movable between an open position and a closed position. In certain embodiments, a pair of hinges 30 may be provided to pivotally mount the rear panel 26 with respect to the other parts of the dumpster portion 12. When the rear panel 26 is in a closed configuration, the rear panel 26 substantially closes the rear end of the dumpster portion 12. A lock mechanism 34 may be used to retain the rear panel 26 in the closed configuration.
When the rear panel 26 is in an open configuration, the rear panel 26 may be positioned adjacent to one of the side panels 20 so that the rear end of the dumpster portion 12 is substantially open. The open configuration may facilitate loading and unloading of items in the dumpster portion 20. A retaining mechanism such as a chain may be provided on the dumpster portion 12 to retain the rear panel 26 in the open configuration.
The portable toilet housing portion 14 may include side panels 40, a top panel 42, a bottom panel 44 that define a rectangular enclosure, which is adapted to receive at least one portable toilet 82 as illustrated in FIGS. 1, 2, 6 and 7. In certain embodiments, the rectangular enclosure is adapted to receive two portable toilets that are oriented to face opposite sides of the dumpster and portable toilet system 10. This configuration enables the interiors of the portable toilets to be accessed while the portable toilets are in the portable toilet housing portion 14.
To increase a strength of the portable toilet housing portion 14, at least one reinforcing member 46 may be provided along at least one of the side panels 40 so that the reinforcing member 46 extends between the top panel 42 and the bottom panel 44. At least one reinforcing member 48 may also be provided along the bottom panel 44 so that the reinforcing member 48 extends between the side panels 40.
While it is illustrated that the side panels 40 and the bottom panel 44 are fabricated from a solid sheet of material, it is possible for the side panels 40 and the bottom panels 44 to have alternate configurations such as being formed with a plurality of holes therein similar to the top panel 42. Alternatively, the portable toilet housing portion 14 may be fabricated without the panels covering the framework.
A lift loop 50 may be provided on the portable toilet housing portion 14 to facilitate movement of the portable toilet housing portion 14. The lift loop 50 may be attached to at least one gusset 52 that extends between the side panels 40. The at least one gusset 52 increases the strength of the portable toilet housing portion 14 to thereby reduce the potential of damage to the portable toilet housing portion 14 during the lifting process.
Depending on the type of hoist mechanism 84 that is provided on the transport vehicle 80, a doghouse recess 54 may extend into the portable toilet housing portion 14 to accommodate a portion of the lift mechanism. A cover may be provided over at least a portion of the doghouse recess 54, as illustrated in FIG. 6. A person of skill in the art will appreciate that the hoist mechanism 84 may assume a variety of configurations, examples of which include a arm (illustrated in FIG. 8).
The portable toilet housing portion 14 is removably attached to the dumpster and portable toilet system 10. Removably attaching the portable toilet housing portion 14 enhances the efficiency at which the dumpster and portable toilet system 10 can be shipped during the manufacturing and distribution process.
In certain embodiments, the bottom panel 22 extends under the location at which it is desired for the portable toilet housing portion 14 to be mounted. The bottom panel 44 of the portable toilet housing portion 14 includes at least one elongated slot 60 formed therein. The elongated slot 60 is adapted to receive a screw 62 that extends through an aperture in the bottom panel 22.
The elongated slot 60 can be oriented generally parallel to a length of the dumpster and portable toilet system 10 from the front and rear ends thereof. The elongated slot 60 thereby enables a position of the portable toilet housing portion 14 to be adjusted with respect to the other portions of the dumpster and portable toilet system 10.
A chassis 28 may be provided on a lower surface thereof to facilitate moving the dumpster and portable toilet system onto and off of a transport vehicle. In certain embodiments, the chassis 28 comprises two rails that are mounted in a spaced-apart configuration. The rails may extend substantially between the front and rear ends of the dumpster and portable toilet system 10. The dumpster and portable toilet system 10 may be equipped with rollers or casters to aid in the positioning and movement of the dumpster and portable toilet system 10.
Portable toilets 82 contained within the toilet housing portion 14 can be secured by locking a chain around the portable toilet housing portion 14, thereby preventing the removal of the portable toilet 82 from the portable toilet housing portion 14. Alternatively, the portable toilet housing portion 14 can be equipped with lock bars (not shown) that span between the side panels 40 and are detachably locked to the portable toilet housing portion 14.
As an alternative to forming the portable toilet 82 separate from the other components of the portable toilet housing portion 14, it is possible that the portable toilet 82 may be integrally fabricated as part of the portable toilet housing portion 14.
In operation, The dumpster and portable toilet system 10 is fabricated with the dumpster portion 12 attached to the chassis 28. This configuration provides the invention with an appearance that is similar to the configuration set forth in FIGS. 3-5. The portable toilet housing portion 14 is fabricated separate from the other aspects of the dumpster and portable toilet system. In this configuration, the portable toilet housing portion 14 has a shape that is similar to illustrated in FIGS. 6 and 7.
The components of dumpster and portable toilet system 10 are shipped to a desired use location such as by placing at least a portion of the portable toilet housing portion 14 in the dumpster portion 12. Alternatively, the portable toilet housing portion 14 may be positioned on its side adjacent to the dumpster portion 12. Using such a configuration reduces the overall height of the components during the shipping and distribution process because a height of the portable toilet housing portion 14 when attached to the chassis may be taller than the dumpster portion 12 as illustrated in FIG. 1.
Because of the reduced overall height of the components in this configuration, it may be possible to stack two of the dumpster and portable toilet systems 10 on top of each other on a conventional flatbed trailer and have the overall height of such a configuration not exceed applicable height regulations such that no special permit is required for the vehicle to travel over most roads.
Once the dumpster and portable toilet system 10 is delivered, the portable toilet housing 14 may be positioned on an attachment region proximate a forward end of the chassis 28 as illustrated in FIGS. 1 and 2 and then attached to the chassis 28 by extending bolts through the elongated slots 60. During the process of positioning the portable toilet housing 14 on the chassis 28, a lifting mechanism (not shown) can utilize the lift loop 50 to facilitate lifting and positioning of the portable toilet housing 14. The dumpster and portable toilet system 10 is then ready for delivery to a location for use.
The dumpster and portable toilet system 10 is placed on the transport vehicle 80 and delivered to the use location. While it is possible to place the portable toilet 82 in the dumpster and portable toilet system 10 after delivery to the use location, the portable toilet 82 is preferably placed in the dumpster and portable toilet system 10 prior to delivery to the use location.
Once at the use location, the dumpster and portable toilet system 10 is moved off of the transport vehicle 80 using the hoist mechanism 84. The fresh liquid pump system is used to place fresh liquid in the portable toilet. The transport vehicle 80 may include a fresh liquid storage tank as well as a pumping system for conveying the fresh liquid from the fresh liquid storage tank to the portable toilet.
The dumpster and portable toilet system 10 is then used by placing refuse in the dumpster portion 20 and using the portable toilet 82 for collection of bodily excrements such as urination and defecation. When done using the dumpster and portable toilet system 10, the transport vehicle 80 returns to the use location.
Prior to placing the dumpster and portable toilet system 10 on the transport vehicle 80 with the hoist mechanism 84, a waste pump 86 may be used to remove waste from the portable toilet 82. The waste pump 86 may be attached to the transport vehicle 80 and cause the waste to be transferred to a waste storage tank on the transport vehicle 80. It is also possible to utilize a cover to prevent the liquid from splashing outside of the designated portion of the portable toilet 82 during the transportation process.
Alternatively, if the portable toilet 82 needs service prior to filling of the dumpster portion 20 with refuse, the waste pump 86 may be used to remove waste from the portable toilet 82 and then the fresh liquid pump 88 may be used to place fresh liquid into the portable toilet 82.
In the preceding detailed description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. In this regard, directional terminology, such as “top,” “bottom,” “front,” “back,” “leading,” “trailing,” etc., is used with reference to the orientation of the Figure(s) being described.
