Definitions

  • the present invention relates to a fastening device for fastening an outboard drive to a boat and an outboard drive for a boat.
  • Outboard drives and motors are a common means of propulsion for boats. They are usually attached to the stern of the boat via a mounting device, particularly a transom mount. Boats can have various stern shapes. If the transom has a flat stern plate, it is also referred to as a "transom.”
  • the transom can be inclined at different angles relative to the water surface. It can be perpendicular to the water surface, protrude diagonally above the water surface, or be tilted toward the interior of the boat. Furthermore, the inclination of the transom relative to the water surface can vary depending on the boat's operating and/or loading conditions.
  • the propeller shaft of the outboard drive's propeller unit i.e., the propeller's rotation axis
  • triming refers to tilting or pivoting the outboard motor, or more precisely, a shaft unit of the outboard motor holding the propeller shaft, about its transverse axis, or about the transverse axis of the boat, in order to adjust the position of the outboard motor, in particular the propeller axis, with respect to the water surface. Accordingly, it is common practice to provide various trim positions, particularly in the form of pivot positions, for the outboard motor.
  • Trimming is usually done once to adjust the alignment of the outboard drive unit for normal operation later during use, more precisely the axis of rotation of the propeller in relation to the boat to which the outboard drive is attached.
  • trim hole into which the trim bolt is inserted is selected so that the shaft unit, in a rest position and/or during anticipated or actual normal operation, is oriented as close as possible to a vertical alignment to the water surface, or the propeller shaft is oriented as close as possible to an alignment parallel to the (theoretically mirror-smooth) water surface, i.e. as close as possible to 0° to the water surface.
  • This initially selected trim position represents the permanent trim position of the outboard motor, or more precisely of the propeller shaft, i.e. the 0° position.
  • tilt also refers to the tilting or pivoting of the outboard motor about its transverse axis, or about the transverse axis of the boat.
  • tilting essentially refers to the purpose of pivoting the outboard motor from an operating position, such as the trim position (0° position), in which the outboard motor is submerged in the water, to a safety or parking position in which the outboard motor is pivoted as far out of the water as possible.
  • the above-water position achieved by tilting the outboard motor, or more precisely the propeller unit, out of the water is referred to as the "tilt position.”
  • An outboard motor is typically attached or secured to the transom of a boat using a bracket, such as a clamp or transom mount. If a boat doesn't have a transom as such, for example, because it has an open stern, a mounting plate is usually provided in the stern area for attaching the outboard motor. If the mounting plate is essentially perpendicular to the water surface or at a typical angle as described above and is suitable for accommodating an outboard motor, it is also included in the term "transom" below.
  • Brackets can fix an outboard motor in various positions to provide pivoting positions for the outboard motor.
  • the US 8,684,328 B2 A fastening device for a pivoting outboard motor mount that can be attached to various mounting positions on differently shaped boats.
  • a locking element is attached to a shaft of the outboard motor by means of a clamping screw and engages two parallel, toothed quarter-circle discs of the device.
  • pivoting the outboard motor can be difficult for the user. To do so, the user must first loosen the clamping screw of the locking element, then pivot the outboard motor and hold it in the desired target position, while simultaneously readjusting and clamping the locking element.
  • the outboard motor is rigidly connected to the mount in the preset position in the locked state, particularly fixed in its pivoting position. In shallow waters, there is therefore a risk that the outboard motor could collide with an underwater obstacle or the bottom of the water, thus damaging the outboard motor, the mounting device, and/or the boat.
  • an outboard drive is shown with a fastening device which can be pivoted between an underwater position provided as an operating position and an above-water position representing a tilt position, wherein a blocking block is spring-loaded into a first blocking position in the underwater position and is spring-loaded into a second blocking position in the above-water position.
  • a fastening device for fastening an outboard drive to a boat comprising a fastening unit which is designed to fasten the outboard drive, more precisely the fastening device, to the boat, and a swing unit which is pivotable about a predetermined transverse axis around the fastening unit and which is designed to hold a shaft unit of the outboard drive.
  • a lever unit is arranged, via which the swing unit can be positioned relative to the fastening unit at at least three different pivoting positions.
  • the swing unit can be positioned relative to the fastening unit at at least four different pivoting positions.
  • the swing arm unit can be adjusted to any of the aforementioned pivot positions by operating the lever unit.
  • positioning in at least three different pivoting positions can be achieved by the single lever unit.
  • functions such as tilt, reverse lock, shallow water position, and run-up protection can be easily operated using a single lever unit. This operation can preferably be simplified one-handed.
  • the outboard drive can be conveniently raised with several swivel positions.
  • pivoting the outboard motor about its transverse axis, or about the transverse axis of the boat particularly includes trimming and/or tilting. Accordingly, when pivoting positions of the outboard motor are described below, both trim and tilt positions of the outboard motor are included.
  • the three pivot positions mentioned above can therefore include, for example, two trim positions and one tilt position.
  • the swing arm unit, and thus the pivotable part of the outboard motor can be positioned both in the tilt position and in at least two trim positions using the single lever unit.
  • Other pivot positions can also preferably be provided, for example, a fixed trim position and at least three or four tilt positions.
  • the longitudinal axis of a mounting device and/or an outboard drive corresponds to an axis which, in a properly mounted condition in which the The outboard drive is attached to the boat by means of the fastening device, or the fastening device is attached to the boat, in a longitudinal direction, i.e., a bow-to-stern direction of the boat.
  • the transverse direction is perpendicular to the longitudinal axis and corresponds to a starboard-to-port direction. In the intended resting position of the boat in mirror-smooth water, the longitudinal and transverse directions are oriented essentially parallel to the water surface.
  • an orthogonal reference system common for vehicles is used to describe the fastening device and the outboard drive, particularly with respect to the outboard motor to be attached to the boat.
  • the X-axis denotes the longitudinal axis
  • the Y-axis the transverse axis
  • the Z-axis the vertical axis of the boat when the boat is used as intended, that is, in particular when the boat is in the water. This allows the position and direction of the individual components of the proposed device, in the properly attached state, to be specified with respect to the outboard motor attached to the boat by means of the device.
  • one of the pivot positions can correspond to a trim position of a drive unit connected to the swing arm unit.
  • the fastening device can thus be designed such that the swing arm unit is positioned in the trim position relative to the fastening unit via the lever unit.
  • two, three, or particularly preferably four tilt positions can be provided as pivot positions.
  • the swing unit can then be moved out of the trim position and then positioned in one of the tilt positions.
  • a "trim position” corresponds to the operating position described in the technical background, in which the propeller axis of the propeller unit is oriented as parallel as possible or even essentially parallel to the direction of travel or the (theoretically smooth) water surface.
  • a slightly tilted trim position may also be provided, for example, to support the boat's behavior during the transition from displacement to planing.
  • a “downward swing” corresponds to a swing in which the center of gravity of the swiveled object, for example the swing unit, with the mounting unit properly attached to the boat, is moved relative to the mounting unit by the Transverse axis, to a lower height relative to the direction of gravity.
  • An “upward pivot” corresponds to a pivot in which the center of gravity of the pivoted object, for example, the swing arm unit, with the mounting unit properly attached to the boat, is moved relative to the mounting unit around the transverse axis, to a higher height relative to the direction of gravity. To achieve this, a moment must be applied that counteracts the moment about the transverse axis acting on the swing arm unit via the gravitational force and the mass of the swing arm unit, including its attachments.
  • a swivel position can correspond to a tilt position of the drive unit connected to the swing arm unit.
  • the tilt position can be a securing and/or parking position in which the outboard motor is pivoted as far as possible out of the water for securing and/or parking purposes.
  • the tilt position generally corresponds to a maximum upward swivel position of the swing arm unit, in which a shaft unit arranged on the swing arm unit and the propeller unit arranged on it are pivoted as far as possible out of the water. It can correspond to an above-water position of the propeller unit or, synonymously, of the outboard motor, more precisely of the shaft unit and the propeller unit.
  • the tilt position therefore represents an upper or stern-direction end position of the swing arm unit.
  • more than one tilt position can be provided, for example, a first tilt position in which the swing arm unit is pivoted upwards by approximately 90° relative to the trim position, and a second tilt position in which the swing arm unit is pivoted upwards by approximately 75° relative to the trim position.
  • the tilt positions have in common that they represent the above-water positions of the outboard drive, more specifically, the shaft unit and the propeller unit.
  • bow-side or “bow-side swiveling” and “stern-side” or “stern-side swiveling” refer to the displacement of a propeller unit connected to the swing arm unit in relation to the bow-stern direction, i.e., the X-axis of the boat, when the fastening device is properly attached to the boat.
  • “Bow-side” corresponds to a displacement of the swing arm unit or the propeller unit, more precisely, for example, a center of gravity of the swing arm unit or the propeller unit, bowward, i.e., towards the bow of the boat.
  • “Stern-side” corresponds to a displacement of the Swing unit or the propeller unit, more precisely for example the center of gravity of the swing unit or the propeller unit, sternward, i.e. in the direction of the stern of the boat.
  • At least one pivot position can correspond to a shallow water position of the drive unit connected to the swing unit.
  • the swing unit can be positioned in two different or multiple shallow water positions, or optionally, a plurality of shallow water positions can be provided.
  • a “shallow water position” corresponds to an operating position of the outboard drive, or more precisely, the outboard motor, in which the rocker unit is pivoted upwards, i.e., toward the stern, relative to the trim position. This reduces the draft of the outboard drive, as the propeller unit, located on the underside of the shaft unit, is less immersed in the water. Accordingly, the boat with an outboard drive positioned in a shallow water position can be operated in shallower waters than in the trim position without the outboard drive colliding with underwater objects, such as the waterbed and/or rocks, tree stumps, or other obstacles.
  • the shallow water position can be specified with respect to a designated trim position, for example a predetermined lowest trim position of a plurality of predeterminable trim positions, for example via the angle around the transverse axis at which the swing unit is pivoted relative to its orientation in the designated trim position in the shallow water position.
  • a designated trim position for example a predetermined lowest trim position of a plurality of predeterminable trim positions, for example via the angle around the transverse axis at which the swing unit is pivoted relative to its orientation in the designated trim position in the shallow water position.
  • a shallow water position therefore corresponds to a position between the trim position and the tilt position, in which the propeller of the propeller unit is still under water, so that propulsion of the boat can be provided via it.
  • Example swivel angles of the shallow water position(s) with which the swing unit is swivelled around the transverse axis to the intended trim position can, for example, be in a range of greater than 0°, optionally greater than or equal to 5°, 10°, 15°, 20° or 25° and/or less than 90°, Optionally, the angles are less than or equal to 80°, 75°, 70°, 60°, 50°, or 45°.
  • a shallow water position can have a tilt angle of 20°, 30°, 40°, or 45° relative to the trim position.
  • the maximum possible angle of the shallow water position depends on the shape of the outboard drive, in particular the length of the shaft unit and the size of the propeller unit. In the shallow water position, the propeller unit is positioned underwater to generate propulsion.
  • the fastening device can be designed such that the swing unit can be positioned relative to the fastening unit selectively in the trim position, at least one tilt position and at least one shallow water position.
  • the lever unit can be switched to a locking position, in which the lever unit fixes the swing unit relative to the fastening unit to prevent pivoting.
  • the lever unit in the locking position, can fix the swing unit in the trim position.
  • the lever unit in the locked position, can fix the swing arm unit to a trim bolt located on the mounting unit.
  • the lever unit can optionally include a locking stop that engages the trim bolt on the bow side when in the locked position.
  • the lever unit can be switched to an anti-run position, in which the lever unit is configured to enable the swing arm unit to pivot in the stern direction.
  • the lever unit can be disengaged from the trim bolt on the bow side of the trim bolt in the anti-run position, and the locking stop can optionally be disengaged from the trim bolt in the anti-run position.
  • the lever unit can be selectively switched to the locking position and the anti-collision position when the swing arm unit is in the trim position. In the trim position, it is then possible to switch between a locked state of the swing arm unit relative to the fastening unit and an anti-collision state of the swing arm unit, in which the swing arm unit can pivot rearward and upward toward the rear, by switching the lever unit either to the locking position or to the anti-collision position.
  • a run-up protection device is understood to mean a functionality that is suitable for protecting an outboard motor from damage or minimizing damage when the propeller unit in an operating position collides or threatens to collide with an underwater obstacle, for example rocks or the bottom of the body of water, during a relative movement of the boat to the surrounding water.
  • a passive run-up protection device is understood here to mean that in the event of a collision between the propeller unit and/or the shaft unit supporting it and an underwater obstacle, the force exerted by the collision on the propeller unit and/or shaft unit is used as a force vector, which acts as a leverage force via the shaft unit and the swing arm unit connected to it and thus generates a pivoting moment to pivot the outboard motor about the transverse axis.
  • This allows the momentum of the collision to be converted into a pivoting movement of the propeller unit, the shaft unit, and the swing arm unit, thus preventing or reducing potential damage to the outboard motor.
  • the outboard motor can yield to the collision momentum with the aid of the device by converting the energy of the collision momentum into the previously described pivoting moment about the transverse axis.

  • the brake unit 490 therefore represents a parking brake which holds the tiller 420 in the set position by means of a clamping force, i.e. locks it, and after overcoming the adhesive force allows the tiller 420 to pivot against the friction force provided via the brake unit 490.
  • Figure 29 and Figure 30 each show the outboard drive 400 according to Figure 12 , wherein the tiller 420 is raised from the normal position into the second pivoting direction, i.e. upwards, into various positions in which it is held, i.e. fixed, by the braking unit 490.
  • the tiller 420 can be lifted from the normal position to a predetermined maximum lifting angle, i.e. a maximum lifting position, in the second pivoting direction.
  • the brake unit 490 also holds the tiller 420 in the parking position via frictional force or adhesive force, thus locking it in the parking position and preventing it from unintentionally pivoting about the pivot axis 422 in the second direction, i.e. out of the intended parking position.
