Beverage can crusher

Abstract

A free standing, portable and hand operated beverage can crushing apparatus to crush individual cans and allow them to drop into a storage container. Included is a rigid support frame that holds the angled crushing chamber where the cans are inserted. A lid is pivotally attached to the top of the support frame above the chamber. Attached to the lid is a ram that holds a roller head assembly that engages the can while the wheels on the roller head rotate across the end cap of the can as external force is continually applied to the lids extended lever arm in a downward motion causing the can to be crushed. The lever arm when raised slightly from the closed position will allow the crushed can to fall by gravity from the chamber into the receptacle that is capable of holding numerous cans.

DETAILED DESCRIPTIONFIGS. 1, 2, 3

(6) One embodiment of the beverage can crusher is illustrated in FIG. 1 (Perspective View). The can crushing apparatus includes a ridged, free standing support frame 12 that is constructed to be slightly less than waist tall. The frame is composed of a floor base 46, a pair of opposing rear vertical members 48, a pair of opposing front angled members 50, a rear horizontal beam 24, a rear horizontal top beam 52, and a front horizontal beam 26. The frame members are rigidly adjoined. The frame members can be made from a various selection of materials including wood, tubular steel, aluminum, or high strength plastics and adjoined by various methods and accessories.

(7) FIG. 1 shows the receptacle 14 that stores the can opener tabs and the cans after they have been crushed. The receptacle is derived from using a typical trash bin or clothes type hamper and lining it with a standard plastic trash bag.

(8) The chamber 16 which is sized to be just slightly larger than the diameter of a typical beverage can is attached to the rear horizontal beam 24 and resting on the front horizontal beam 26. The lid 22 is attached to the support frame 12 at the rear horizontal top beam 52 using a pivot mechanism 36. The lever arm 34 is the narrowed extended end of the lid 22.

(9) As illustrated in FIG. 2, the ram 18 is rigidly attached to the lid 22. It is located at a defined distance from the pivot 36 which will allow it to enter the chamber 16 and the slot 42 when the lid 22 is swung closed. The ram is made of a thin () strong metal. At the end of the ram 18 is the ram roller head 20 which consists of an axel and lock nuts 32 that hold the roller wheels 30 which contact the can during crushing.

(10) The chamber 16 is attached to the rear horizontal beam 24 by the end plate 38 that is the rear termini of the chamber as shown in FIG. 3. The rear horizontal beam 24 is constructed at a defined angle with the rear vertical plane of the support frame 12 and at a defined distance below the pivot 36 such that when the lid 22 is swung downward the ram roller head 20 enters the chamber 16 via the cut-out 28 and continues through the chamber to the final closed position without any contact between the ram roller head components and the chamber.

(11) There is a cut-away 28 in the front upper half of the chamber 16 to allow the wheels 30 to enter the chamber and contact the beverage can 44 as the lid is brought forward. The slot 42 in the center of the top of the chamber 16 allows the ram 18 to pass through during the crushing process. There is a discharge opening 40 at the rear of the chamber 16 to allow the crushed can to fall freely, without attention, into the receptacle 14 once the lid 22 is raised slightly to remove the down force of the ram head on the crushed can.

(12) OperationFIGS. 1, 2, 3, 4

(13) As shown in FIG. 4, the apparatus is at rest with the rotating lid 22 in the horizontal or down position, with the underside against the top of the rigid support frame 12. The lid is designed to be a safety feature, that it covers the chamber 16 and does not permit access to pinch points.

(14) The user would grip the lever arm 34 of the lid 22 and raise the lever arm, making the lid to move about the pivot 36 and continue to raise the lid to a near vertical position or open position as shown in FIG. 1. An aluminum beverage can 44 is placed into the chamber 16 as the lid is held in the open position as illustrated in FIG. 2. Once the can is inserted until it comes into contact with the end plate 38, the hand used to insert the can is cleared. The lever 34 is then swung downward and the roller wheels 30 make contact with the end cap of the beverage can as shown in FIG. 3. As the lever is continued to be forced downward, beginning the crushing process, the ram roller head 20 enters the chamber, the roller wheels 30 will rotate down the end cap of the beverage can while crushing force is transferred in the axial direction of the can and the ram roller head 20 travels toward the end plate 38. This continues until the lid reaches the closed position and the crushing limit is reached.

(15) FIG. 3 depicts the rotation of the roller wheels 30 down the end cap of the aluminum can 44 as the ram 18 along with the lever 34 and lid 22 is swung through its crushing path.

(16) From the closed position as shown in FIG. 4, the user can the raise the lever 34 slightly to allow the crushed can to freely drop without attention through the discharge opening 40 and into the receptacle 14, or the can be left in place until another can is need to be crushed and once the lever 34 is raised to gain access to the chamber 16 the previously crushed can will then fall.

(17) When the receptacle 14 has been filled it can be taken from between the support frame 12 to allow the plastic bag full of crushed cans to be removed and a new bag installed and the receptacle placed back into position.

(18) While the present invention has been shown and illustrated in terms of a specific apparatus, it is apparent that various modifications and changes in detail thereof may be made without departing from the spirit and scope of the invention.

(19) Advantages

(20) From the description above, a number of advantages of same embodiments of this can crusher become evident: a) The free standing unit is light weight and portable which allows it to be located where the user desires. b) The simple design is inexpensive to manufacture, making to accessible to more individuals. c) Nearly all of the manual force applied to the lids lever arm is transferred to the crushing of the beverage can through the ram roller head without wasted energy. d) The angled chamber and discharge opening allowing for free fall of the crushed cans is a major convenience factor. e) Having a recycling receptacle incorporated allows storage of the cans and can opener tabs at the unit. f) The crusher and receptacle is similar in size to a typical kitchen garbage bin, thus minimum space is required for the unit.
Ramifications

(21) Although the description above contains much specificity, it should not be construed as limiting the scope of the embodiments but merely providing illustrations of some of several embodiments. For example, the crushers support frame could be made in similar configurations with various materials or it could be an enclosed, box-type rather than a member frame unit. The lever arm could be extending or telescoping type. Also, the chamber could be shaped differentlytriangular, trapezoidal, or oval, and be made of a variety of materials as long as they can withstand forces applied to crush the cans and the capable of withstanding the scraping of the aluminum beverage can against the sides during the crushing process.
