The present device relates to aluminum cans. More particularly, the disclosed device relates to a portable hand-operated aluminum can crushing apparatus which automatically ejects crushed cans to chute communicating the crushed can to a breathable collection bag, without the need for the user to touch the can subsequent to compacting.
Worldwide, the manufacture and sale of beverages in cans has become the predominant manner in which soft drinks and other beverages are manufactured and sold to customers. However, customers for such beverages must either collect the empty cans in receptacles for recycling, which can become large and unwieldy, or simply throw them in the trash. The disposing of such aluminum cans in the trash is ecologically unsound due to the ease which aluminum, if collected, can be recycled.
Numerous can collection devices have been manufactured and sold in recent years. To aid in collection storage and recycling of aluminum drink cans, can crushers have also been manufactured and sold to consumers for the purposes of compacting empty cans so they may be stored and recycled.
The forgoing background concerning conventional can crushing devices and limitations related therewith are intended to be illustrative and not exclusive, and they do not imply any limitations on the invention described and claimed herein. Various other limitations of the related art are known or will become apparent to those skilled in the art upon a reading and understanding of the specification below and the accompanying drawings.
The portable hand-operated can crushing device and system herein disclosed is structured to provide functions not found in the conventional can crushing devices in prior art and achieves the above noted objects through the provision of portable hand-operated can crushing device, which automatically ejects crushed cans to a breathable bag. Thereafter the compacted collected cans within the bag can be taken to a recycling center for recycling in an ecologically positive manner.
The device herein features a can crusher having a cavity in which an empty can is positioned, which will accommodate a large variety of empty beverage can sizes. The device features a primary handle which generates mechanical advantage in a rotating engagement with members which translate a compacting member positioned on an upper end of a cavity. The cavity is accessible for insertion of a can with the handle elevated. However, once the compression action is initiated by a user, the cavity is surrounded by a housing sidewall and a cover, thereby protecting the user from accidentally positioning portions of their hand in a position which could cause injury.
Once the can has been compressed within the cavity surrounded by the housing and cavity cover, the can may be ejected into a chute, by a slight lifting of the handle in a direction away from a base within the cavity on which the crushed can is positioned. A lifting connector, engaged between a compacting member and the base, causes the base to pivot on a rotating connection to the housing of the device. This slants the base in a manner to cause the compacted can, to slide through a second opening and into a chute, without the need for the user to touch the compacted can with their hand.
A bag operatively engaged to a portion of the device surrounding the chute in which cans are ejected collects the compacted cans within an interior chamber of the bag. The bag is formed preferably of breathable fabric. Once the bag is removed and the cans held therein deposited to a larger container, the bag may be rinsed and reused, thereby eliminating the waste of collecting crushed beverages in plastic bags which are disposed.
With respect to the above description, before explaining at least one preferred embodiment of the herein disclosed hand-operated can crushing invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangement of the components in the following description or illustrated in the drawings.

It is an object of the present invention to provide a lightweight and easily mounted aluminum can crushing device to encourage use and the ecological recycling of multiple sized aluminum cans, by a large portion of households.
It is an additional object of this invention to provide such a can crushing device which requires no electric power to operate.
It is yet another object of the invention herein, to provide a can crushing device which automatically ejects crushed cans to a breathable and reusable bag subsequent to compacting, thereby eliminating the need for users to touch the crushed can with their hands.
It is a further object of this invention, to provide a can crushing device, which surrounds a cavity in which the can is compacted, with a housing to thereby form a shield to prevent pinching of fingers of the user and other potential injuries which may occur during the crushing cycle.
An additional object of this invention is the provision of such a can crushing device, which automatically ejects a crushed can into a breathable mesh duffel or bag, to eliminate the need for the user to touch the crushed can which may be dirty and/or have potential sharp projections thereon which could injure the user.
These and other objects, features, and advantages of the present can crushing invention, as well as the advantages thereof over existing prior art, which will become apparent from the description to follow, are accomplished by the improvements described in this specification and hereinafter described in the following detailed description which fully discloses the invention, but should not be considered as placing limitations thereon.
The accompanying drawings, which are incorporated herein and form a part of the specification, illustrate some, but not the only or exclusive examples of embodiments and/or features of the disclosed hand-operated automatic ejecting can crushing device. It is intended that the embodiments and figures disclosed herein are to be considered illustrative of the invention herein, rather than limiting in any fashion.
In the drawings:
In this description, the directional prepositions of up, upwardly, down, downwardly, front, back, top, upper, bottom, lower, left, right, first, second, and other such terms refer to the device as it is oriented and appears in the drawings and all such terms are used for convenience only and such are not intended to be limiting or to imply that the device has to be used or positioned in any particular orientation.
Now referring to drawings in
A first end of a connecting member 24 is in a rotational engagement 30 to the handle 12, adjacent a second end of the handle 12, which is opposite a grip 28 end of the handle 12. By rotational engagement is meant that a connection between the connecting member 24 and the handle 12 allows that connection to rotate as the handle 12 moves up and down, and that connection causes translation of the connecting member 24 as the handle 12 moves up and down.
A length of a portion of the handle 12 between the grip 28, and the rotational engagement 30 of the handle 12 to the connecting member 24, in combination with the fixed pivoting engagement 12 of the handle 12 to the housing 16, provides for significant mechanical advantage in operation of the device 10.
This mechanical advantage allows the user to easily force the compacting member 24 toward the base 32 of the internal cavity 22 which is located at an opposite end of the internal cavity 22 from the compacting member 26 when the handle is raised to the first position of

Shown in
During this crushing or compacting of a can 34, the can 34 positioned within the internal cavity 22 will be surrounded by the sidewall 44 of the housing 16 on three sides, and by housing cover 18 shown in
As noted, in
The device 10 herein, in all modes, preferably has a base 32 which is in a rotating connection 46 (
A lifting connector 48 which is operatively engaged to the compacting member 24 or to the handle 12, is actuated to move toward and away from the base 32, by movement of the handle 12 between the elevated position of the handle and lowered position of the handle 12. Movement of the handle 12 from the elevated position toward the lowered position thereof, will move the projecting member 54 of the lifting connector 48, in a first movement and in a first direction, from a first position, raised and out of magnetic and/or physical contact with the base 32, toward the base 32.
Once movement in this first direction places the projecting member 54 of the lifting connector 48 in a second position where it is in contact with the base 32, or in position connectively proximate thereto, it will form a removable engagement with the base 32. By connectively proximate is meant that the connector such as a magnet upon the projecting member 54 forming part of the lifting connector 48, is positioned close enough to the base 32, that a temporary magnetic connection is formed, or in the case of releasable fastener such as hook and loop fabric, the hook and loop fabric located on the projecting member 54 and the base 32, are positioned close enough to form a contact between hook and loop fabric, operatively positioned on the base 32 and the projecting member 54 of the lift connector 48.
The lifting connector 48, while in the second position where the projecting member 54 is lowered and the removable engagement is formed with the base 32, (such as in
In the case of a magnetic attraction the removable engagement will detach once the magnet 50 on the projecting member 54 of the lifting connector 48 moves far enough from the magnetically attractive material 52 on the base 32. In the case of a mechanical lifting connector 48, such as hook and loop fabric, the removable engagement will detach once the projecting member 54 of the lifting connector 48 moves a sufficient distance in the second direction, to cause detachment between hook and loop fabric located on the end of the lifting connector 48 and on the base 32.
As noted, this lifting connector 48 when in such a removable engagement, operates to rotate the base 32 on the rotating connection 46, and thereby to raise a second side of the base 32, opposite the first side having the rotating connection 46 and thereby move the base to the tilted position as in
This lifting connector 48 (
While shown as the magnet 50 being on a spring loaded projecting member 54 connected to the compacting member 26, the magnet 50 could be positioned on the base 32 with the magnetically attractive material 52 being positioned in an engagement with a spring loaded projecting member 54. As shown in
A biasing member 55 or component, such as a spring, will serve to continuously bias the projecting member 54 toward a position projecting from the compacting member 24, wherein the magnet 50 can contact against or be positioned adjacent the base 32, and exert a pulling force upon the magnetic attractive material 52, to exert force to thereby pull the base 32 to the angled position of
The magnet 50 and magnetically attractive material 52, such as iron or nickel, are preferred as the self-releasing lifting connector 48, because in experimentation with multiple releasing connectors this combination worked well and was not overly affected by liquids or metal shards or the like from the can. Further, using such magnetic attraction, rather then a mechanical connection, the force to lift the base 32 is provided, but does not require an actual connection or contact therewith, which can jam or become otherwise contaminated over time by metal or liquids. However, for a lesser performing device, the releasing lift connector shown herein as 48, may also be formed of other self releasing connective components such as hook and loop fabric, gearing which releases, or other temporarily mating components which release once the base 32 has reached the angle A, to allow the can to slide, and the handle moves further upward.
In
Additionally preferred is the formation of a chute 38 having a chute wall 62 which surrounds the first opening 60 of the chute 38, where the chute wall 62 has a lower or recessed portion 64 positioned on a side of the chute wall 62, which is adjacent and substantially aligned with the second opening 36. Such worked well on occasions where the handle 12 is lifted quickly from the second position, to activate the tilting of the base 32, which imparted additional force to eject the can 34 through the second opening 36. The recessed portion 64 of the chute wall 62 has a top edge located in a position lower than the connection 46 of the base 32 to the sidewall 44 as in
The chute wall 62 surrounding the chute 38, on the opposite side from the recessed portion 64, has a top edge which is located at a height equal to that of the rotating connection 46, and higher than the top edge of the recessed portion 64. This chute wall 62 thus forms a backstop for an ejected can 34 sliding from the base to contact, and then drop into the chute 38.
By having a top edge located equal to or higher is meant, that this top edge is at or above an imaginary line 35 (
While the device will function with just the chute 38 and without the chute wall 62 and recessed portion 64, the device herein was found to work better to catch and deposit cans 34 into the chute 38, with the inclusion of the chute wall 62. The chute wall 62 acted to contact and redirect cans 34 passing through the recessed portion 64 thereof, into the chute 38, and thereby prevented cans 34 from missing entry into the chute 38.

As an example and in no way limiting, the mesh or breathable fabric may be knitted or woven or non-woven polymeric monofilament, or a polymeric coated mesh scrim, such as for example PHIFERTEX from Phifer Mills.
Where the breathable bag 56 is included with the device 10, a closure or bag connector 66 such as a drawstring, tie, cord, or other flexible member with a releasable cord lock 67, or another releasable bag connector 66, will be positioned in an engagement with the wall of the bag 56 at a position surrounding the open end 57 of the bag 56, through which the cans 34 communicate to the interior chamber 58 of the bag 56. The releasable bag connector 66 for example can be positioned within a pocket or hem, formed around the open end 57 of the bag 56, and cinched to hold the bag 56 on the ledge 68. In this fashion the open end 57 of the bag 56 can be removably engaged to a ledge 68 surrounding the chute 38, using the bag connector 56, during the collection of ejected compacted cans. Once sufficiently full, the bag 56 may be removed by releasing the cord lock 67, and emptied, and then re-engaged to the ledge 68 or another connection area surrounding the chute 38.
