The present invention relates to accessory devices for trash cans. More particularly, the present invention provides a lid stabilizing device for a trash can that maintains the lid in a closed position yet automatically releases and resets when the trash can is turned over to be emptied and returned to an upright position.
Many municipalities and other areas have developed standardized garbage collection operations that include specialized disposal vehicles. These operations typically utilize a common type of trash can that is adapted to be grasped by lifting arms on the specialized disposal vehicle. The specialized disposal vehicle lifting arms lift the trash can and rotate it simultaneously to dump its contents into the waste storage area of the specialized disposal vehicle before placing the trash can back down on the ground in its original upright orientation. These types of trash cans typically include a pivotally affixed lid that opens automatically as the disposal vehicle dumps the contents of the trash can. Because the lid must open automatically as the trash can is dumped, the lid typically does not have any kind of closure latch or other lid securing mechanism. When the trash can is returned to an upright orientation, the lid sometimes returns to a closed position under its own weight, but no fastener is included for maintaining that closed position over time.
While necessary for the operation of the disposal vehicle, having a lid that cannot be secured closed presents additional problems. For example, the lid does not always return to a closed position when placed upright. Even when in a closed position, wind often causes the trash can lid to blow open and act like a sail. The lid catches the wind and causes the trash can to blow down the street where it must be located and retrieved. The lid being open also allows unwanted odors to escape from the interior of the trash can, and further allows unwanted insects or larger animals to access the contents of the trash can. In order to solve these problems, some individuals use rocks or other heavy objects to weigh down the lid. However, these are cumbersome and can cause injury if they fall from the lid. They also may cause damage to the overall structure of the trash can and prevent the disposal vehicle from properly dumping the trash can. In view of the above concerns, it is desirable to provide an accessory device that can be secured to a trash can which allows the trash can's hinged lid to open as normal when the trash can is dumped by the disposal vehicle, yet functions as a closure fastener to maintain the lid in a closed position when the trash can is returned to the ground in its original upright orientation.
Some devices in the known art exist that are designed to attach to trash cans in an attempt to secure the trash can lid in a closed position. However, the devices in the known art have several disadvantages and drawbacks, and do not adequately address the issue of keeping the trash can lid closed due to blowing wind or similar weather conditions without causing additional problems. For example, most devices in the known art lack the ability for the lid to swing open automatically when the trash can is dumped, and then automatically return to the closed position when placed upright again. The devices in the known art typically include complicated fastener arrangements that are prone to failure and that also must be manually engaged or disengaged by an individual. These devices require an individual or the disposal vehicle operator to leave the vehicle and open the lid manually. The individual may forget to latch or unlatch the device which would like to ineffectiveness. Further, if the disposal vehicle operator were required to manually operate the devices in the known art to open or close the lid, the garbage retrieval process would be made more inconvenient and inefficient. Additionally, a trash can may be blown over by the wind, and such mechanical latches are prone to breaking or failure when the can hits the ground. Also, if the latch has not been re-secured by an individual, the lid will open and trash will potentially spill, as well as causing the fallen can to catch wind more easily and potentially be blown further away.
In light of the devices disclosed in the known art, it is submitted that the present invention substantially diverges in functional and design elements from the known art and consequently it is clear that there is a need in the art for an improvement to garbage can lid retention and closure systems. In this regard the present invention substantially fulfills these needs
In view of the foregoing disadvantages inherent in the known types of trash can lid latches and retainers now present in the prior art, the present invention provides a trash can automatic lid stabilizer, wherein the same can be utilized for conveniently maintaining the lid in a closed position when the trash can is upright, which automatically disengages to allow the lid to open when the trash can is emptied, and automatically re-engages to secure the lid in place when the trash can is returned to an upright position.
The trash can automatic lid stabilizer generally includes a base that is securable to the perimeter sidewall of a trash can. The base can be integral to the trash can or attached with different types of fasteners. An arm is pivotally connected to an upper end of the base. The pivoting connection may be an adjustable hinge pin that can be adjusted to control the rotational speed of the arm when gravity acts on the arm. A first magnetic coupler is disposed on an upper end of the arm. A second magnetic coupler can be integrally formed with or connected to the lid of the trash can, such that the first magnetic coupler is configured to removably secure to the second magnetic coupler. The arm is configured to rotate away from the trash can when the trash can is rotated to an upended position and the lid moves to an open position, and further configured to rotate toward the trash can and overtop the lid after the lid returns to a closed position when the trash can is rotated to an upright position. In this way, the arm retains the lid in a closed position when the trash can is upright, but allows the trash can to be emptied without requiring an individual to manually disengage the magnetic connectors.
One object of the present invention is to provide a trash can automatic lid stabilizer with magnetic couplers that will remain coupled to maintain the trash can lid in the closed position even if the trash can accidentally falls over.
Other objects, features and advantages of the present invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings.
Although the characteristic features of this invention will be particularly pointed out in the claims, the invention itself and manner in which it may be made and used may be better understood after a review of the following description, taken in connection with the accompanying drawings wherein like numeral annotations are provided throughout.
Reference is made herein to the attached drawings. Like reference numerals are used throughout the drawings to depict like or similar elements of the trash can automatic lid stabilizer. For the purposes of presenting a brief and clear description of the present invention, the preferred embodiment will be discussed as used for conveniently maintaining the lid in a closed position when the trash can is upright, while automatically disengaging to allow the lid to open when the trash can is emptied, and automatically re-engaging to secure the lid in place when the trash can is returned to an upright position. The figures are intended for representative purposes only and should not be considered to be limiting in any respect.

An arm 12 is pivotally connected to an upper end of the base 11, such that the arm can rotate about the pivot point. In the shown embodiments, the arm 12 is connected to the base 11 via a hinge pin, which may be adjustable. In other embodiments, other pivoting connections may be utilized. A first magnetic coupler 13 is disposed on an upper end of the arm 12, which removably engages a second magnetic coupler, as shown in
The device further includes an angled stop 14 that is configured to limit the rotation movement of the arm 12 as it rotates away from the trash can lid when the trash can is upended and dumped. In the shown embodiment, the angled stop 14 extends upwardly from the base 11, such that a lower end 17 of the arm 12 contacts the angled stop 14 and is prevent from over rotating. In the shown embodiment, the angled stop 14 prevents the arm 12 from rotating more than thirty degrees with respect to the vertically oriented base 11. This positioning ensures that the arm 12 will always rotate back overtop the closed lid when the trash can is returned to an upright position after being dumped. The hinge pin can be adjusted to control the rate of movement of the arm 12, ensuring that the lid will close before the arm 12 rotates back overtop the lid. In other embodiments, the pivoting connection between the arm 12 and base 11 can include a spring hinge which biases the arm 12 to the lowered or closed position overtop the lid 31. Such a spring hinge would be similarly adjustable to control the relative rate of rotation of the arm 12, ensuring it will always lower after the lid 31 closes.

The arm 12 is shown in a raised position rotated away from the lid 31 of the trash can, which occurs automatically when the trash can is turned upside down and emptied of its contents. In the shown embodiment, the hinge pin 15 includes an adjustable fastener 19, which can tighten or loosen the pivoting connection between the base 11 and arm 12. As the fastener 19 is tightened, more friction is applied, so the arm 12 will rotate back toward the lid 31 more slowly. As the fastener 19 is loosened, less friction is applied, so the arm 12 will rotate back toward the lid 31 more quickly when the trash can is returned to the upright position. The fastener 19 can thus be adjusted to ensure that the lid 31 returns to the closed position more quickly than the arm 12 rotates back to the closed position when the trash can is turned back to its upright orientation, ensuring that the arm 12 will always rotate overtop the lid 31.
