Description

BACKGROUND

Field of the Invention

This invention relates to a lid opener. More particularly, the invention relates to a lid opener capable of opening the lid of a waste container without the use of hands.

Description of Related Art

A variety of similarly shaped and functioning containers are available for temporary storage and disposal of waste. Curbside waste containers, in particular, have been, to a significant extent, standardized. Typical curbside waste containers are similar in shape and size. Curbside waste containers generally have a lid that is attached to a handle on the top back of the waste container. It is also common for curbside waste containers to be designed so as to be easily lifted by a robotic arm of a waste disposal vehicle.

Be that as it may, it is often awkward, or even difficult, to open the lid of waste containers with one's hands. For example, it is difficult to open the lid of a waste container while encumbered by bags or articles of trash. It is not uncommon to find it necessary to set items on the ground, or to shift items between hands, in order to lift the lid of a waste container. Furthermore, the lid of waste containers often fall backwards easily, slamming against the back of the waste container. Conventional solutions tend to be bulky and complex. Many solutions involve encasement of the waste container, to one degree or another, within a frame or docking station. This results in high costs and inconvenience in assembly, installation, and removal. Some solutions fail to restrict the tendency of the lid to flip over, necessitating additional effort to shut the lid and generating unwanted noise; while other solutions do not allow the lid to flip backwards, even if so desired. As an additional inconvenience, many standard lid openers must be removed from the waste container prior to curbside pickup. Furthermore, many lid openers are specific to a particular size or style of waste container, reducing efficiencies of scale, and consequently, increasing costs.

Therefore, it is an object of the invention to provide a lid opener and method of manufacture that overcomes deficiencies of the prior art.

DETAILED DESCRIPTION

The inventor has observed that many conventional lid openers for waste containers are overly bulky and consist of too many complexly interconnected parts. The inventor has also observed that many conventional lid openers either do not restrict the tendency of the lid to flip backwards or entirely impede the lid from flipping backwards. It has further come to the attention of the inventor that many lid openers must be temporarily removed before curbside trash pickup. Moreover, the inventor has noticed that many lid openers are specifically designed for waste containers of particular sizes or styles, and thus, are not sufficiently universal. Accordingly, the inventor has recognized that it is possible to overcome these difficulties, while decreasing the costs and inconveniences associated with assembly, installation, and removal, by providing a lid opener that is less bulky, less complex, and comprises fewer components than can be found in the prior art.

An exemplary embodiment of a lid opener 1 for interconnection with a waste container 3 with a handle 5 and a lid 7 with a back edge 9 is demonstrated in FIGS. 1-12. The waste container 3, and its discrete parts, is not claimed below and is shown in FIGS. 10-12 only as an example of a typical container with which the lid opener 1 may be interconnected.

The lid opener 1 is provided with a lever 11 dimensioned to pivotally couple with the handle 5. The lever 11 is comprised of a mid portion 13, a force portion 15, and a load portion 17. When interconnected with the waste container 3, a section of the mid portion 13 of the lever 11 functions as a fulcrum, pivoting about the handle 5. The lever 11 may be made of metal, fiberglass, plastic, or other sufficiently strong and rigid material, or combination of materials. The lever 11 may be monolithic, as shown in the exemplary embodiment of FIGS. 1-3 and 7-12. The lever 11 may, alternatively, be comprised of more than one part coupled so as to achieve sufficient strength and rigidity to maintain the weight of a waste container lid.

The lever 11 may be provided with a flange 19 dimensioned longitudinally along at least a portion of each side along the length of the lever 11, adding additional strength and durability to the lever 11.

The load portion 17 of the lever 11 is dimensioned to extend underneath the lid 7 of the waste container 3. For example, as shown in the exemplary embodiment of FIGS. 1-3 and 7-12, the load portion 17 of the lever 11 may be provided with a notch 21 dimensioned to receive the back edge 9 of the lid 7, allowing the lever 11 to extend underneath the lid 7 when the lid 7 is closed. The lid opener 1 further comprises a cord 23 coupled with the force portion 15 of the lever 11, as shown in FIGS. 10-12. The cord 23 may be a cord, strip, string, rope, strand, cable, belt, chain, or any similarly functioning elongated material. The cord 23 may be made of any of a variety of materials, including, but not limited to, nylon, metal, polypropylene, or other natural or synthetic material or composite of materials. The cord 23 may be removably or fixedly coupled with the force portion 15 of the lever 11. For example, the force portion 15 of the lever 11 may be provided with an aperture 25h proximate a first side 27 of the lever 11 and an aperture 25i proximate a second side 29 of the lever 11. The ends of the cord 23 may be coupled with the force portion 15 of the lever 11 via the apertures 25 on the force portion 15 of the lever 11. The ends of the cord 23, may, for example, be tied around the apertures 25 on the force portion 15 of the lever 11. Alternatively, the cord 23 may be coupled to the apertures 25 of the force portion 15 of the lever 11 via fasteners, such as clips. Accordingly, when interconnected with the waste container 3, downward force applied to the cord 23 will cause the lever 11 to pivot about the handle 5 and open the lid 7.

The cord 23 may be dimensioned to wrap around the waste container 3 such that a foot may easily be placed upon the cord 23. Furthermore, the length of the cord 23 may be adjustable. For example, the length of the cord 23 may be adjustable from five to ten feet. The cord 23 may be made adjustable in a variety of ways. For example, the cord 23 may be coupled with a buckle. As another example, the cord 23 may be made adjustable by tying off the ends of the cord 23 around the apertures 25 on the force portion 15 of the lever 11 at different lengths.

The lid opener 1 may further comprise a stabilizer 31 coupled with the load portion 17 of the lever 11. The stabilizer 31 may be made of plastic, medal, or any other sufficiently strong and rigid material. Furthermore, the stabilizer 31 may be any of a variety of shapes and sizes. For example, the stabilizer 31 may be tubular. The stabilizer 31 may be provided with a stabilizer slit 33. The load portion 17 of the lever 11 may be provided with a load end flange 35. Accordingly, the load portion 17 of the lever 11 may be removably coupled with the stabilizer 31 by inserting the load end flange 35 into the stabilizer slit 33 of the stabilizer 31. The load portion 17 of the lever 11 may also be attached to the stabilizer 31, for example, by the use of glue or other adhesive, or by attachment via fasteners, such as screws. Alternatively, the load portion 17 of the lever 11 may be dimensioned to distribute force to the bottom of the lid 7 without the use of the stabilizer 31. For example, the load portion 17 may be provided with a flat surface dimensioned to directly contact and support the bottom of the lid 7 of the waste container 3.

The lid opener 1 may further comprise a pedal 37 dimensioned to couple with the cord 23. For example, the pedal 37 may be tubular. Accordingly, the pedal 37 may be coupled with the cord 23 by stringing the cord 23 though the pedal 37 such that a mid section of the cord 23 resides within the pedal 37. The pedal 37 may be dimensioned to rest against the front of the waste container 3 when coupled with the cord 23. As best shown in FIG. 4, for example, the pedal 37 may be dimensioned with two or more extended flat edges 39. As another example, a side of the pedal 37 may be flat. The pedal 37 may further be provided with one or more ridge 41 to provide a gripping surface when force is applied to the pedal 37, for example, by a foot.

The exemplary lid opener 1 may further comprise a brace 43. The brace 43 may be used to secure the lever 11 to the handle 5 of the waste container 3. The brace 43 may be any of a variety of shapes, sizes, and materials. For example, the brace may be a metal wire fashioned into a U shape, with terminating ends 45 of the wire parallel. The brace 43 may further be fashioned to curve upward proximate a non-terminating end 47 of the brace 43. The brace 43 may be coupled with the lever 11 such that the upward curve of the brace 43 enables the brace 43 to extend underneath the handle 5 of the waste container 3 when coupled with the lever 11, with the lever 11 resting on top of the handle 5 of the waste container 3. For example, the brace 43 may be removably coupled with the lever 11 by providing the mid portion 13 of the lever 11 with at least one aperture 25 proximate the first side 27 of the lever 11 aligned with at least one aperture 25 proximate the second side 29 of the lever 11. The brace 43 may accordingly be dimensioned to pass through two of the apertures 25 along the first side 27 and the second side 29 of the mid portion 13 of the lever 11 and underneath the handle 5 of the waste container 3.

At least a portion of the force portion 15 of the lever 11 may be angled downward. Providing an angle to at least a portion of the force portion 15 of the lever 11 serves, in part, to limit the distance the lid 7 of the waste container 3 is able to open with a given amount of applied force, which helps to prevent the lid 7 of the waste container 3 from opening completely and slamming against the back of the waste container 3. Furthermore, by providing the force portion 15 with a downward angle, the terminating ends 45 of the brace 43 may be brought into contact with the lever 11 after passing underneath the handle 5. The terminating ends 45 of the brace 43 may then be coupled with the force portion 15 of the lever 11, securely surrounding the handle 5 of the waste container 3 to hold the lid opener 1 in place.

For example, the force portion 15 of the lever 11 may be provided with a central cavity 49. The central cavity 49 may be a cutout section of the force portion 15, fully or partially enclosed by inner sides of the lever 11. The brace 43 may be dimensioned to extend through the central cavity 49 of the lever 11. The force portion 15 of the brace 43 may further be provided with a catch 51. The catch 51 may, for example, be portions of the lever 11 extending inward from the central cavity 49. The lever 11 and brace 43 may be dimensioned such that, when the brace 43 is coupled with the lever 11, the terminating ends 45 of the brace 43 extend through the central cavity 49 and rest upon the catch 51. In the exemplary embodiment described, tension from rigidity of the brace 43 will secure the brace 43 within the central cavity 49 and against the catch 51. The brace 43 may be coupled and uncoupled with the lever 11 by gently squeezing the terminating ends 47 of the brace 43 together and away from the catch 51. Thus, in the exemplary embodiment, as best shown in FIGS. 7-9 and FIGS. 11-12, the lever 11 may be dimensioned to securely and pivotally couple with the handle 5 of the waste container 3 via the brace 43, by coupling the brace 43 with the lever 11 around the handle 5 of the waste container 3.

The lever 11 and brace 43 may be designed to adjustably couple, thereby adjusting the position of the fulcrum of the lever 11. For example, the lever 11 may be provided with more than one set of apertures 25 along the first side 27 and the second side 29 of the mid portion 13 of the lever 11. Inserting the brace 43 into alternative sets of apertures 25 along the mid portion 13 of the lever 11 allows the lid opener 1 to be attached securely, pivotally, and removably, to a variety of differently dimensioned waste containers. Significantly, adjustable positioning of the brace 43 enables the notch 21 of the lever 11 to be positioned to receive the back edge 9 of the lid 7 of the waste container 3, while still allowing the lever 11, coupled with the brace 43, to be securely attached to the handle 5 of the waste container 3.

With normal use of the exemplary embodiment of FIGS. 1-12, applying an average amount of force to the pedal 37, the lid 7 of the waste container 3 will rise, but will not flip over, allowing the lid 7 to close, due to gravity, when force is no longer applied to the pedal 37. However, if a sufficient amount of force is applied quickly to the pedal 37, the lid 7 of the waste container 3 will flip completely backward. The lid opener 1, unlike other solutions found in the prior art, will restrain, but not completely impede, flipping the lid 7 of the waste container 3. By controlling the amount of force applied to the pedal 37, the lid 7 of the waste container 3 may be opened partially or fully.

In a method of manufacturing the lid opener 1 of the exemplary embodiment of FIGS. 1-12, a lever 11 is formed to pivotally couple with a handle 5 of a waste container 3 with a handle 5 and a lid 7 with a back edge 9. A force portion 15 of the lever 11 is dimensioned to couple with a cord 23. A load portion 17 of the lever 11 is manufactured to extend underneath the lid 7, whereby downward force applied to the cord 23 causes the lever 11 to pivot about the handle 5 and open the lid 7. The load portion 17 of the lever 11 may be manufactured to include a notch 21 dimensioned to receive the back edge 9 of the lid 7. The load portion 17 may also be provided with one or more apertures 25a for reasons related to manufacturing of the lever. For example, the one or more apertures 25a could be used to hang the lever 11 to dry after painting the lever 11. A brace 43 may be formed to pivotally couple the lever 11 with the handle 5. A pedal 37 may be dimensioned to couple with a mid section of the cord 23. The pedal 37 may further be formed to rest against the front of the waste container 3.
