  • Sand-trap rake with an extruded head
    Patent number: 5605034
    Abstract: A rake (140) includes an elongated head (142) and an elongated handle (144). The elongated head (142) includes a white-metal extruded head blank (148) with a tooth-blanking flange (154) and a handle-attaching flange (158). A plurality of rake teeth (186) are blanked, or otherwise defined, in the tooth-blanking flange (154). A pair of identical handle-attaching brackets (202) each having both a semi-cylindrical portion (206) and a flange portion (208) are used to attach the elongated handle (144) to the elongated head (142). The elongated head (142) includes a lifting portion (162) that cooperates with the rake teeth (186) in a raking step, an ironing portion (166) that provides an ironing step, and a secondary smoothing portion (170) for use in a supplemental smoothing step.

  • Sand-trap rake with oppositely-angled teeth
    Patent number: 5544476
    Abstract: A rake (10), for smoothing sand surfaces (18A and 18B) in response to pulling the rake (10) along a longitudinal axis (22), includes an elongated head (26) that is disposed transversely to the longitudinal axis (22), and that includes first (52A) and second (52B) pluralities of blades (54A and 54B). Trailing edges (70) of each blade (54A or 54B) are disposed closer to the longitudinal axis (22) than leading edges (68), thereof; so that grains (122A and 122B) of sand are moved transversely inward toward the longitudinal axis (22). The elongated head (26) includes a front curvilinear surface (58) that raises the elongated head (26), a rear curvilinear surface (62) that irons the surface (16), and a flattened portion (66) that floats the elongated head (26) during the raking step.
