  • Patent number: 11642580
    Abstract: A sand trap rake for use on golf courses includes an elongate rake head having an elongate body member with a front end, a back end, and first and second lateral sides between the front and back ends. The rake head defines a raking direction aligned with a direction extending from the front end to the back end. A plurality of tines extend downwardly from the body member and are spaced apart along a longitudinal direction of the rake head, transverse to the raking direction. The rake further includes an elongate front blade extending downwardly from the front end of the body member, and an elongate rear blade extending downwardly from the back end of the body member. The rake may be used in one of four selectable raking modes to prepare a sand surface for golf play.

  • Publication number: 20190230849
    Abstract: A sand trap rake includes an elongate rake head having a first, front end and a second, back end. The rake head defines a raking direction aligned with a direction extending from the first end to the second end. A plurality of tines are spaced apart along a longitudinal direction of the rake head, transverse to the raking direction. The rake further includes a first elongate smoothing member disposed forwardly from the first end of the rake head, and a second elongate smoothing member disposed rearwardly from the second end. Longitudinal extents of the first and second smoothing members are generally aligned with the longitudinal direction of the rake head. The rake may be used to repair a sand surface by pushing or pulling the rake head along the surface so that sand is directed through the tines and over at least one of the first or second smoothing members.

  • Publication number: 20090293213
    Abstract: A sweeper apparatus is disclosed, which concerns at least one wheel, at least one brush and a means for attaching a pulling agent. The wheels are pulled in one direction causing the one or more brushes to spin at a desired speed flicking sand particles into small or large holes on the ground. The brushes are in mechanical cooperation with the wheels allowing the wheels and brushes to spin in substantially opposite directions. The wheels are driven through the use of a pulling agent like golf cart, truckster, tractor or other movement device which can cause the sweeping apparatus to be moved over a desired area.
