摘要： A mulching lawn mower has a closed cutting chamber in a mulching mode such that the grass clippings are confined within the cutting chamber except for when they fall out through the open bottom face of the chamber. The cutting chamber has a first portion of toroidal or doughnut form generally closely surrounding the blade tips. In addition, the front portion of the cutting chamber includes a forwardly protruding wedge-shaped extension having side walls that converge towards one another in a pie-shaped fashion. The wedge-shaped extension further includes a top wall that extends between the side walls. This top wall is sloped or inclined downwardly as it extends to the front of the mower such that the height of the wedge-shaped extension gradually decreases until the wedge-shaped extension disappears at its front edge. The wedge-shaped extension reduces power consumption of the mower when the mower is placed in its mulching mode and is used to mulch grass.
摘要翻译：覆盖草坪割草机具有覆盖模式的封闭切割室，使得草屑被限制在切割室内，除了当它们从室的敞开的底面脱落时。切割室具有通常紧密围绕叶片尖端的环形或环形形状的第一部分。此外，切割室的前部包括向前突出的楔形延伸部，其具有以饼状方式朝向彼此会聚的侧壁。楔形延伸部还包括在侧壁之间延伸的顶壁。该顶壁倾斜或向下倾斜，因为其延伸到割草机的前部，使得楔形延伸部的高度逐渐减小，直到楔形延伸部在其前边缘处消失。当割草机放置在覆盖模式中时，楔形延伸部可以减少割草机的功耗，并用于覆盖草坪。

摘要： A power box (12) for a low voltage lighting system (10). Power box (12), which connects to a 120 VAC source via 120 VAC cable (15) and a plurality of low voltage light fixtures (14) via a 12 VAC cable (16), includes a "tortuous path" strain relief (40) including a first strain relief structure (41) in a base (19) having vertically spaced horizontal ribs (44, 46, 48) and a second strain relief structure (43) in a cover (28) having corresponding vertically spaced horizontal ribs (56, 54, 52). When base (19) and cover (28) are assembled, structures (41 and 43) align such that the ribs interdigitate or mesh to form the tortuous path strain relief (40) for the 120 VAC cable (15). Another aspect of the invention is the use of a standard spade lug connector (77) and a pair of "double-L" spade lug connectors (78) for making the internal and external 12 VAC connections to a step down transformer (60) and the 12 VAC cable (16), respectively. Another aspect of the present invention is a power box mounting system which includes a horizontal groove (90) on the rear wall (27) of power box (12), and a vertical slot (94) extending upwardly from groove (90) and also formed in the rear wall (27). Groove (90) and slot (94) are configured to receive a power box mounting screw (92), in that order. Still another aspect of the present invention resides in the fact that the base (19) and cover (28) of power box (12) can accommodate a variety of electrical components, including either a 36 watt transformer (60') or a 72 watt transformer (60").

摘要： A cable connector (82) including a thermal fuse (25) for use with a low voltage electrical system (1). The preferred connector (82) includes a pair of electrically and thermally conductive jumper elements (19,23) with a plurality of sharpened edges (30,33,64,67) for piercing the insulating jacket (32,35,73,74) surrounding the inner conductors (14,15,22,24) with which the jumpers (19,23) make electrical contact. The jumpers (19,23) include a plurality of conductor engaging slots (31,34,65,66,68,69) which mechanically grip the conductors. In operation, the quality of the electrical contact between the jumpers and the conductors is proportional to the amount of heat radiated at the junction between the terminals (26,27,62,63) and the conductors (14,15,22,24), the heat causing the thermal fuse (25) to break the electrical circuit when the sensed heat exceeds a predetermined threshold.

摘要： A cable connector for a low voltage electrical system. A preferred connector (22) includes a pair of electrically conductive jumper elements (62a, 62b) with a pair of spaced sharp protrusions (66) that are electrically connected. The preferred connector (22) includes a cap (52) consisting of electrically resistive material with means for engaging the jumper elements (62a, 62b). The preferred cable connector (22) includes a base (24) consisting of electrically resistive material with a plurality of channel-like cavities (26, 28, 30, 32) for accepting low voltage electrical cables (36, 38). The base (24) is sized so as to nest within cap (52) and the cavities (26, 28, 30, 32) are sized so as to receive the sharp protrusions (66) so that the cables (36, 38) are penetrated by the protrusions (66) and the base (24) nests within the cap (52). The preferred cable connector (22) also includes a fastening means for retaining cap (52) to the base (24) wherein the protrusions (66) penetrate the insulating material of the cables (36, 38) and make electrical contact with the conductive material of the cables (36, 38).

摘要： A light fixture (10) including a bulb/lens assembly (12), a hollow post (14) and a ground stake (16). An assembly ring (18) having inner and outer "fingers" (104 and 106, respectively) securely connects the bulb/lens assembly (12) to the post (14). Bulb/lens assembly (12) includes a lens (28) which carries a plurality of louvers (40, 42 and 44). Some of the louvers include legs (46, 50) and slots (60, 62) so that the distance between the louvers can be adjusted to vary the appearance of light fixture (10) and the amount of light produced thereby.
