  • Patent number: 8714277
    Abstract: Tool (1) for engagement in the ground including a holding portion (9) for turning of the tool around an axis of rotation (3), wherein an engagement portion (2) has a plurality of cutting blades (4) extending in directions from the holding portion (9) and being distributed around the axis of rotation (3) for pressing down into and engagement with the ground, said cutting blades each having a proximal end (5) and a distal free end (6). The cutting blades (4) have a respective front edge (7), for cutting action against the ground and a respective rear edge (8), wherein points on the front edges (7) are positioned at a greater distance from the axis of rotation (3) than points on the rear edges (8), and the cutting blades (4) are angled such that a distal portion of each rear edge is positioned in front of as seen in the turning direction (v), and essentially at the same distance from the axis of rotation (3) as a proximal portion thereof.

  • Patent number: 7673913
    Abstract: A golf ball retrieval tool including an elongated handle which carries at one end a cage. The cage has a first section located near the elongated section and a second section located distally from the handle and connected to the first section. The first cage section has a first opening opened in a first tool orientation to freely receive a golf ball. The second section includes a downwardly open second opening which forms a ball seating. When the tool is in the first cage orientation, the handle extends obliquely downwards beneath the horizontal plane of the cage. The cage further includes a roof structure which in response to pressing the cage generally vertically against a ball generates on the ball a wedging action such as to drive the ball into the second section where the ball can be received in the ball seating.

  • Publication number: 20070120385
    Abstract: A golf ball retrieval tool comprising an elongate handle (1) which carries at one end a so-called cage (20) which has at its rear end that faces towards the handle (1) a first section (21) and at a part distal from said handle a second section (22) which connects with said first section (21), wherein in a first cage orientation of the tool the first cage section has an opening edge (21) which, in said first tool orientation, is generally open downwards and rearwards towards the handle and which is able to freely receive a golf ball, wherein a transit opening (32) connects the first section (21) with the second section (22), wherein the second section includes a downwardly open opening (33) which forms a ball seating, wherein, with the tool in said first cage orientation, the handle extends obliquely downwards beneath the horizontal plane of the cage (22), and wherein the transit opening (32) between said first and said second sections forms a threshold (35) over which the ball must run.
