Abstract: A trimmer line, hook disk system forming a line trimmer head (e.g., FIGS. 10 & 10A, 19 & 20) for attaching to a powered, rotational device (FIGS. 11-16) to provide a line filament grasscutting/weed-removal action. The trimmer head preferably includes a circular, protective, bottom base (D2/60/160), a main trimmer head top (D3/D30/130), the two forming a disk shape, and a series of peripherally spaced, line holders; with these three basic elements fastened together for ultimate attachment to the powered 31 device. Ten exemplary line holder are shown (FIGS. 1-9B), with most allowing oscillating (O) motion in their attachment to the trimmer device (D1), allowing the lines to move backwardly when contacting a relatively hard item, and/or some fixed (F). A “broom” embodiment is disclosed (FIG. 17). When used, flexible line, e.g. of nylon, is inserted in (1) and held (2) by the line holders preferably using hook or hook-like line attachments.

Abstract: A trimmer line, hook disk system in the form of a line trimmer head (e.g. FIGS. 11 & 11A) as a replacement for attaching to a powered, rotational device to provide a line filament grass cutting action, which trimmer head includes a circular, protective base or bottom (D2), a circular, main trimmer head substrate (D3), the two forming a disk shape, and a series of peripherally spaced line holders; with these three basic elements attached together with appropriate fasteners for ultimate attachment to a powered device. Eleven exemplary line holders are shown in FIGS. 1-10B, respectively, with some allowing oscillating (O) motion in their attachment to the trimmer head substrate (D3) and/or fixed (F) in their attachment. A “broom” embodiment is shown in FIG. 18. When in use, flexible line made, for example, of nylon, is inserted in and held by the line holders preferably using hook or hook-like line attachments.

Abstract: A weed trimmer apparatus having a head defining at least one side wall, the side wall forming one or more apertures therethrough, and one or more line retention members for retaining one or more trimmer lines. The line retention members are operatively connected to the head, wherein each line retention member is sized and configured to extend through a loop of at least one trimmer line during operation of the weed trimmer apparatus and wherein each line retention member is dynamically connected to the head to allow for installation and removal of the loop of trimmer line.

Abstract: A trimmer line, hook disk system forming a line trimmer head (e.g., FIGS. 11 & 11A, 20 & 21) for attaching to a powered, rotational device (FIGS. 12-17) to provide a line filament grasscutting/weed-removal action.

Abstract: A trimming line segment (100) is attached to a button-like, locking element (200; see FIGS. 5-8 for various embodiments) by inserting their distal tips (101) and adjacent line sections into a pair of holes (201) in the locking element and pulling them through (FIGS. 1A-1C). The distal tips of the line of the assembled line/element (300) are then inserted via the interior into holes in the side wall of a rotatable head, either that provided to house a spool (6) of filament line that has been removed (FIGS. 9A & 9B, and 10) or that of an attachment 20 (FIGS. 12A-D). When the powered, trimming device is rotated, the newly inserted line, held in place by the button-like locking element, then does the cutting and trimming of weeds and the like or even sweeping.

Abstract: Implements for attaching to a hand-held, powered device (e.g., “Weed-Eater” type with extended handle or hand tool) to perform various work or chores (filament cutting, blade cutting, brushing, blowing, mixing, etc.). After disconnecting the device's original implement, an initial, cultivator/cutter implement (10), cylindrical in shape with a substantially solid, circular top (12) and a relatively thin, continuous wall of constant thickness, is attached by an appropriate threaded member (e.g. a nut or bolt, usually with one or more washers) to the bottom end of the powered device (FIGS. 1A-D, 29) through a central opening (13/313). The cultivator's top can include a series of circumferentially spaced, “snap-in” openings (14; e.g. two or more) through and into which other implements (e.g. those of FIGS. 3-20) can be attached (FIGS.

Abstract: A garden cleaning implement (10/10A) for weeds and the like comprising a cutting mechanism (14) and an adjustable guard mechanism (28) carried on, for example, an extended pole handle (22/122). The cutting mechanism includes an associated spool line shroud (16); an intermediate, rotatable shaft (18); and a rotatable, blade, cutting member (20/120/220). The guard mechanism includes a ring-shaped guard providing a protected area of a size sufficient to cover and protectively encircle over the rotating blade member; and slotted, attachment legs (32) for adjustably attaching the cutting mechanism and handle to the ring guard structure. The relatively rigid, cutting blade member is located under the adjustable, protective guard ring, allowing for protective cutting of, for example, weeds immediately adjacent to, for example, desirable vegetation.

Abstract: A garden cleaning implement (10) for weeds and the like comprising a cutting mechanism (14) and a retractable guard mechanism (28), generally free to "float" up and down about the cutter mechanism, carried on, for example, an extended pole handle (22). The cutting mechanism includes--an associated rotational power source (16/116); an intermediate, rotatable shaft (18) connected thereto; and a rotatable, rectangular blade, cutting member (20).

Abstract: An improved system for shutting off utilities, such as gas and electricity, automatically in the case of an emergency, such as an earthquake, fire and the presence of hazardous fumes. The device includes a box containing the main control unit mounted on the gas main outside the building. The box includes a motion detector which triggers a relay which cuts the power to the gas valve causing the flow of gas to be cut off during an earthquake. An electrical signal is supplied by a smoke detector or a hazardous fumes detector to the relay to trigger the relay and the relay interrupts the power to the gas valve shutting the flow of gas to the building. The relay provides an electrical signal to a power breaker and a water valve in order to shut off electrical and water supply to the building. After the emergency passes and the utilities are checked for damages the system can be reset manually. Power to the box is provided by running a powerline to it.
