Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a divisional of U.S. patent application Ser. No. 13/714,895 filed Dec. 14, 2012 which claims the benefit of U.S. Provisional Patent Application Ser. No. 61/570,648, filed Dec. 14, 2011, the entireties of which are incorporated by reference herein.

FIELD OF THE INVENTION

The invention relates to the field of mulching devices. More specifically, it relates to a low-cost, environmentally friendly mulcher.

BACKGROUND OF THE INVENTION

Hand-manipulated electric blowers with vacuum/mulching features and attachments are convenient for most homeowners. The debris in flower beds and in other areas can be sucked up, mulched and distributed in soil and beds as desired, quickly and conveniently. However, some gardeners are reluctant to use such low cost, hand-manipulated electric blowers with vacuum/mulching features, because in vacuuming/mulching mode, such devices suck up beneficial organisms and creatures which dwell in the soil. Such an outcome is undesirable for these individuals. Moreover, vibrations from hand-manipulated blowers and vacuums can cause hand numbness. In addition, a user is required to carry the mulch bag around with them. One solution is for gardeners to use a stand-alone mulching device. Typical stand-alone mulching machines employ a top-loading hopper so that mulchable debris can be carefully loaded into the device. However, these devices tend to be large and expensive, and inconvenient to move around, compared to the aforementioned hand-manipulated blowers with vacuum/mulching capability, which typically include accessories such as vacuum ducts and collection bags, and are generally available for about $70.

The collection device 60 may be a flexible or rigid material and made of any suitable material.

Now referring to FIGS. 4 and 5, hopper 30 may include connector 32 which is complementary to a connector 42 of a chute 40 or similar connector on the mulching/blower device 20.

In practice, an operator of the apparatus 2 sets up the mulching/blower device 20 in the floor stand 10, attaches the hopper 30 to the mulching/blower device 20, turns on the power and deposits material to be mulched into the hopper. Mulch is ejected from the outlet 24 and may be captured in receptacle 60.

Now referring to FIGS. 6-8, another embodiment of the hopper element 30 is depicted. The hopper element 30 is configured as an intake chute, permitting the blower/vacuum mulcher 20 to be laid on the ground so that leaves may be swept or raked to the chute-like hopper 30 and fed into the mulcher 20. In this embodiment no floor stand is required. Preferably, hopper 30 includes a substantially flat, ground-facing side 31 having a leading edge 33 which extends beyond a leading edge 37 of a side 35 opposite the ground-facing side 31. Hopper 30 may have a receiving end 34 having an opening formed therein which is wider than the opening formed in mulcher attachment end 36. In practice, an operator attaches the hopper 30 to the mulching/blower device 20 and lays the apparatus 2 on the ground, for example, adjacent a leaf pile 100, turns on the power and rakes or blows (suing for example blower 120) material to be mulched into the hopper 30. Mulch is ejected from the outlet 24 and may be captured in receptacle 60.

Now referring to FIG. 7, floor stand 10 may further include a pivoting securing device such as a clamp, clip, brace etc. for securing the mulching/blower device 20 so that it may be selectively positioned. For example, clamp 19 may be positioned in channel 13 and rotatably connected to housing 11 such as by pin 18. Clamp 19 may be adjustable in the manner of a vise to securely and releasably engage the body of mulcher 20. Pin 18 may be equipped with a tensioning knob or set screw to secure clamp 19 in a desired position, such as the “down”, “up”, vertical or another intermediate position. Alternatively, an adjustment device such as a ratchet and pawl device, pin and hole adjustment device or the like may be employed to permit selective positioning of the clamp 19. For example, FIG. 7 depicts the clamp 19 positioned to orient the hopper 30 in a “down” position. Now referring to FIG. 8, the clamp 19 is positioned to orient the hopper 30 in an “up” position. In one embodiment the clamp 19 is rotatable to permit the hopper 30 to be placed in an upright position, perpendicular to the ground.

To facilitate the efficient capture of mulched material, a receptacle support 70 may be provided to support receptacle 60. Receptacle support 70 may be integral with floor stand 10 as shown.
