Description

Technical Field

[0001] The invention relates to a fastening device for fastening an outboard drive to a boat and to an outboard drive for a boat. Background Art

[0002] Outboard drives and outboard motors are known drive mechanisms for boats. Typically, the outboard drives and outboard motors are placed at the stern of the corresponding boat via fastening devices, in particular stern plate holders. The boat can have different stern shapes. If there is a flat stern closure plate, it is also called a "stern closure plate (Spiegel)". The stern closure plate can be tilted differently relative to the water surface. The stern closure plate can be perpendicular to the water surface, obliquely protrude beyond the water surface or tilted toward the inside of the boat. In addition, the inclination of the stern closure plate relative to the water surface can change due to different states of the boat, in particular the driving state and / or the load state.

[0003] In order to be able to operate the outboard drive as optimally as possible, the propeller shaft of the propeller unit of the outboard drive, that is to say the rotational axis of the propeller, should be oriented essentially parallel to the water surface in the intended normal operation. This leads to the necessity of "trimming" the outboard component. In the context of the present disclosure, "trimming" means tilting or pivoting the outboard component, more specifically the shaft unit of the outboard component that holds the propeller shaft, about its transverse axis or about the transverse axis of the ship, in order to thereby adapt the position of the outboard component, in particular the propeller axis, with respect to the water surface. Correspondingly, different trimming positions, in particular trimming positions in the form of pivot positions, are usually provided for the outboard component.

[0004] Trimming is usually performed once to adjust the orientation of the outboard drive unit, more precisely the orientation of the axis of rotation of the propeller relative to the boat on which the outboard drive is mounted, for normal operation which is then set during use.

[0005] For trimming, it is known to provide a plurality of trimming holes spaced apart from one another on the fastening unit and to insert a trimming pin through one of the trimming holes in order to achieve a preset angle of the shaft unit. The trimming hole into which the trimming pin is inserted is selected so that the shaft unit in the rest position and / or in expected or actual normal operation is oriented as close as possible to a perpendicular orientation relative to the water surface or the propeller shaft is oriented as close as possible to an orientation parallel to the (theoretically mirror-smooth) water surface, i.e. as close as possible to a 0° orientation relative to the water surface. The initially selected trimming position is the permanent trimming position of the outboard component, more precisely of the propeller shaft, i.e. the 0° position.

[0006] The term "tilted" likewise denotes a tilting or pivoting of the outboard component about its transverse axis or about the transverse axis of the boat. However, tilting is essentially concerned with the purpose of pivoting the outboard component from an operating position, such as a trim position (0° position), in which the outboard component is immersed in the water, into a safety position or a parking position in which the outboard component is pivoted maximally out of the water. In the disclosure, the position above water reached by tilting the outboard motor, more precisely the propeller unit, out of the water is referred to as the "tilted position".

[0007] Typically, the outboard components are placed or fastened on the transom of the ship by means of holders, such as clamping devices or transom holders. If the ship does not have a true transom, because the ship has an open stern, for example, a mounting plate is usually provided in the stern area for fastening the outboard components. If the mounting plate is essentially vertical with respect to the water surface or is generally inclined as described above and is suitable for accommodating outboard components, then said mounting plate is also included in the term transom.

[0008] Known holders can secure the outboard component in different positions in order to provide a pivot position for the outboard component.

[0009] For example, US 8,684,328 B2 describes a fastening device for pivotably holding an outboard component, which can be fastened in different fastening positions on boats of different shapes. Here, a locking element is fastened to the shaft of the outboard component by means of a clamping screw and engages with two parallel toothed quarter discs of the device. It is considered to be in need of improvement that it may be difficult for the user to operate the pivoting of the outboard component. To this end, the user must first loosen the clamping screw of the locking element, then pivot the outboard component and hold it in the desired target position and at the same time adjust and clamp the locking element again. In addition, when using the device, in the locked state, the outboard component is rigidly connected to the retaining member in a preset position, in particular fixed in its pivot position. Therefore, in shallow water, there is a risk that the outboard component collides with an underwater obstacle or the bottom of the water, thereby damaging the outboard component, the fastening device and / or the boat.

[0010] CN 104627343 A shows an outboard drive with a fastening device, which can be pivoted between an underwater position set as an operating position and an above-water position representing an inclined position, wherein the blocking block is pre-tensioned by a spring into a first blocking position in the underwater position and is pre-tensioned by a spring into a second blocking position in the above-water position. Summary of the invention

[0011] Starting from the known prior art, the object of the present invention is to provide an improved fastening device for fastening an outboard drive to a boat and an improved outboard drive.

[0012] According to a first aspect, this object is achieved by a fastening device according to the invention for fastening an outboard drive to a ship. Advantageous developments emerge from the description and the accompanying drawings.

[0013] Correspondingly, a fastening device for fastening an outboard drive to a boat is proposed, the fastening device comprising: a fastening unit, the fastening unit being configured to fasten the outboard drive, more precisely the fastening device, to the boat; and a swivel unit that can be pivoted about the fastening unit about a predetermined transverse axis, the swivel unit being configured to hold a shaft unit of the outboard drive. A lever unit is provided at the swivel unit, via which the swivel unit can be positioned in at least three different pivot positions relative to the fastening unit. Particularly preferably, the swivel unit can be positioned in at least four different pivot positions relative to the fastening unit.

[0014] Correspondingly, the adjustment of the swivel unit into each of the above-mentioned pivot positions can be carried out via the operating lever unit.

[0015] In particular, positioning in at least three different pivot positions can be achieved by a single lever unit.

[0016] This also makes it possible to reduce the total number of parts of the fastening device compared to conventional devices according to the prior art, in particular cost-intensive stainless steel components and welded assemblies.

[0017] Furthermore, simple operation of functions such as tilting, back locking, shallow water position and collision protection can be achieved, which can all be performed via the (single) lever unit. The operation can preferably be a simplified one-handed operation.

[0018] Accordingly, a comfortable locking of the outboard drive with a plurality of pivot positions can be achieved.

[0019] In the context of the present disclosure, the pivoting of the outboard component about its transverse axis or about the transverse axis of the boat includes in particular trimming and / or tilting. Accordingly, hereinafter, when describing the pivot position of the outboard component, the trim position and the tilt position of the outboard component are included.

[0020] Thus, the three pivot positions mentioned above can include, for example, two trim positions and one tilt position. In other words, the pivotable part of the swing unit and thus of the outboard motor can be positioned not only in a tilt position but also in at least two trim positions by means of a single lever unit. Preferably, further pivot positions can also be provided, for example a fixed trim position and at least three or four tilt positions.

[0021] In the disclosure, the longitudinal axis of the fastening device and / or the outboard drive corresponds to the axis which, in the state in which the outboard drive is fastened to the ship by means of the fastening device or in the state in which the fastening device is fastened to the ship in a prescribed manner, corresponds to the longitudinal direction of the ship, i.e. the fore-aft direction of the ship. The transverse direction is perpendicular to the longitudinal axis and corresponds to the starboard-port direction. In a predetermined rest position of the ship in mirror-smooth water, the longitudinal direction and the transverse direction are oriented substantially parallel to the water surface.

[0022] In the disclosure, in order to describe the fastening device and the outboard drive, in particular with respect to the outboard component to be fastened on the boat, an orthogonal reference system usually used for vehicles is used. In this case, the X-axis represents the longitudinal axis of the boat, the Y-axis represents the transverse axis of the boat, and the Z-axis represents the vertical axis of the boat when the boat is in proper use, i.e., in particular when the boat is in water. The positions and orientations of the individual components of the proposed device are therefore described in the state of proper fastening with respect to the outboard component fastened on the boat by means of the device.

[0023] According to one embodiment, one of the pivot positions can correspond to a trimming position of a drive unit engaged on the pivot unit. The fastening device can therefore be designed such that the pivot unit is positioned relative to the fastening unit in the trimming position via the lever unit.

[0024] According to another embodiment, two, three or particularly preferably four inclined positions can be provided as pivot positions. By means of the lever unit, the pivot unit can be brought out of the trimming position and subsequently positioned in one of the inclined positions.

[0025] The "trimming 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 substantially parallel to the direction of travel or the (theoretically mirror-smooth) water surface. However, depending on the application scenario, a slightly pivoted trimming position can also be provided, for example to support the performance of the watercraft when it transitions from displacement navigation to planing.

[0026] "Pivoting downwards" corresponds to a pivoting in which the center of gravity of the pivoted object, for example the swivel unit, moves relative to the mounting unit about the transverse axis to a lower height level in relation to the direction of gravity when the mounting unit is fastened to the vessel in the state of intended fastening. "Pivoting upwards" corresponds to a pivoting in which the center of gravity of the pivoted object, for example the swivel unit, moves relative to the mounting unit about the transverse axis to a higher height level in relation to the direction of gravity when the mounting unit is fastened to the vessel in the state of intended fastening. Therefore, for this purpose, a moment acting about the transverse axis opposite to the moment acting on the swivel unit via the weight and mass of the swivel unit including the attachment must be applied.

[0027] The pivot position can correspond to an inclined position of a drive unit coupled to the swing unit. The inclined position can be a safety position and / or a parking position in which the outboard component is pivoted as far as possible out of the water for safety purposes and / or parking purposes. The inclined position usually corresponds to a position of the swing unit pivoted upwards to the greatest extent, wherein the shaft unit arranged at the swing unit and the propeller unit arranged thereat are pivoted as far as possible out of the water. The inclined position can correspond to an above-water position of the propeller unit or, synonymously, of the outboard component, more precisely of the shaft unit and of the propeller unit. The inclined position is therefore an end position of the swing unit above or on the stern side.

[0028] Optionally, more than one tilted position may also be provided, for example a first tilted position in which the pivot unit is pivoted upwards, for example by approximately 90°, relative to the trim position, and a second tilted position in which the pivot unit is pivoted upwards, for example by approximately 75°, relative to the trim position. The tilted positions have in common that they are above-water positions of the outboard drive, more precisely of the shaft unit and of the propeller unit.

[0029] The terms "side in the bow direction" or "pivoting in the bow direction" and "side in the stern direction" or "pivoting in the stern direction" relate to the displacement of the propeller unit connected to the swivel unit about the fore-aft direction, i.e. the X-axis of the ship, if the fastening device is arranged on the ship in the specified state. "Side in the bow direction" corresponds to the displacement of the swivel unit or propeller unit, more precisely, for example, the center of gravity of the swivel unit or propeller unit, toward the bow, i.e., toward the bow of the ship. "Stern side" corresponds to the displacement of the swivel unit or propeller unit, more precisely, for example, the center of gravity of the swivel unit or propeller unit, toward the stern, i.e., toward the stern of the ship.

[0030] At least one pivot position can correspond as a shallow water position to a drive unit coupled to the swing unit. Optionally, the swing unit can be positioned in two different or multiple shallow water positions, or optionally multiple shallow water positions can be provided.

[0031] The “shallow position” corresponds to an operating position of the outboard drive, more precisely of the outboard part, in which the pivot unit is in a position pivoted upward, i.e. laterally in the direction of the stern, relative to the trim position. The draft of the outboard drive is thereby reduced, since the propeller unit arranged at the bottom of the shaft unit is immersed less deeply in the water. Accordingly, the boat can be operated with the outboard drive arranged in the shallow position in shallower water than in the trim position, without causing the outboard drive to collide with underwater objects, such as the bottom and / or rocks, tree trunks or other obstacles.

[0032] The shallow water position can be described with respect to a preset trim position, for example a preset lowermost trim position of a plurality of preset trim positions, more precisely, for example via the following angle about the transverse axis, at which angle the swivel unit is pivoted relative to its orientation in the preset trim position in the shallow water position.

[0033] The shallow water position thus corresponds to a position between the trim position and the tilted position, in which position the propeller of the propeller unit is still located under water, so that propulsion of the vessel can be provided via said propeller.

[0034] It has proven to be advantageous if a plurality of different shallow water positions are provided in which the pivoting unit can be positioned relative to the fastening unit.

[0035] Exemplary pivot angles for the shallow water position, at which the swivel unit is pivoted about the transverse axis relative to the predefined trim position, can lie, for example, 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 less than or equal to 80°, 75°, 70°, 60°, 50°, 45°. For example, the shallow water position can have a pivot 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 on the length of the shaft unit and the size of the propeller unit. This is because in the shallow water position the propeller unit is positioned under water so that propulsion can be generated.

[0036] According to an advantageous embodiment, the fastening device can be designed such that the pivoting unit can be selectively positioned relative to the fastening unit in a trimming position, at least one inclined position and at least one shallow water position.

[0037] According to one embodiment, the lever unit can be switched into a locking position in which it fixes the pivot unit relative to the fastening unit against pivoting. For example, the lever unit can fix the pivot unit in the trimming position in the locking position.

[0038] For example, the lever unit in the locking position can fix the pivot unit on a trimming bolt arranged at the fastening unit. The lever unit can optionally include a locking stop which stops on the trimming bolt on the bow side in the locking position.

[0039] Alternatively or additionally, the lever unit can be switched into a crash protection position in which the lever unit is configured to release the stern-side pivoting of the pivot unit. Optionally, the lever unit can be disengaged from the trimming bolt on the bow side of the trimming bolt in the crash protection position, wherein optionally in the crash protection position the locking stop can be disengaged from the trimming bolt.

[0040] Advantageously, when the swivel unit is in the trimming position, the lever unit can be selectively switched into the locking position and the collision protection position. Thus, in the trimming position, by switching the lever unit into the locking position or the collision protection position, it is possible to switch between a locking state of the swivel unit relative to the fastening unit and a collision protection state of the swivel unit, in which the swivel unit can be pivoted laterally rearward and upward in the stern direction.

[0041] In the context of the present disclosure, collision protection is understood to be a function that is suitable for protecting outboard components from damage or minimizing damage when the propeller unit in the operating position collides or faces a collision with an underwater obstacle, such as a rock or the bottom, during the relative movement of the vessel with respect to the surrounding water.

[0042] More precisely, passive collision protection is currently understood to mean that, in the event that the propeller unit and / or the shaft unit supporting the propeller unit collides with an underwater obstacle, the force acting on the propeller unit and / or the shaft unit is used as a force vector, which acts as a lever force via the shaft unit and the swing unit connected to the shaft unit, thereby generating a pivoting moment for pivoting the outboard component around a transverse axis. As a result, the impulse of the collision can be converted into a pivoting movement of the propeller unit, the shaft unit and the swing unit, so that possible damage to the outboard component can be prevented or reduced. In other words, by converting the energy of the collision impulse into the aforementioned pivoting moment around the transverse axis, the outboard component can succumb to the collision impulse with the aid of the device.

[0043] According to one embodiment, the lever unit may include a locking element. For example, in the shallow water position, the lever unit may engage with the locking element in a shallow water locking element receiving portion provided at the fastening unit. If a plurality of shallow water positions are provided, the fastening unit may optionally include a shallow water locking element receiving portion for each of the shallow water positions.

[0044] The shallow water locking element receptacle can optionally be designed so that when the outboard drive is fastened to the ship by means of the fastening device in a state of proper fastening, the swivel unit can be pivoted on the stern side when the resulting pivoting moment acting on the swivel unit exceeds a preset threshold value. The shallow water locking element receptacle can optionally include an inclined ramp on the stern side, which is oriented at a preset angle relative to a tangent to the circumferential direction of the transverse axis and is oriented at a preset angle relative to the tangent to the circumferential direction.

[0045] Alternatively or additionally, in the tilted position the lever unit can engage with the locking element in a tilt locking element receptacle provided at the fastening unit. If a plurality of tilted positions are provided, the fastening unit optionally comprises a tilt locking element receptacle for each of the tilted positions.

[0046] According to one embodiment, the lever unit may include two lever members, wherein a first lever member is pivotably arranged at a swing unit at one side, and a second lever member is pivotably arranged at the first lever member at the other side of the first lever member, and the second lever member is guided at the swing unit via a slide guide member at a distance from a pivotable coupling member to the first lever member.

[0047] According to one embodiment, the lever unit can be locked into a crash protection position, wherein the slide guide of the lever unit optionally comprises a locking receptacle for accommodating a guide element guided in the slide guide, wherein the lever unit optionally locks into the crash protection position when the guide element is accommodated in the locking receptacle. Advantageously, the locking receptacle is arranged at the lower end of the slide guide.

[0048] According to one embodiment, the lever unit may include a prestressing mechanism for prestressing the lever unit in a preset direction, for example, a spring prestressing. Optionally, the prestressing mechanism prestresses the lever unit toward at least one preset position, for example, toward a locking position, a collision protection position and / or a shallow water position or into a locking position, a collision protection position and / or a shallow water position. The prestressing mechanism may include a spring element, for example, a helical spring, which is for example arranged at a support portion of the first lever member that is pivotable relative to the swing unit. The spring element may apply a prestressing force or a prestressing torque to the first lever member, so that the first lever member prestresses the second lever member in a direction preset by the prestressing.

[0049] The fastening device may also be constructed according to one or more of the other aspects described in the disclosure.

[0050] The shaft unit can be a part of the drive unit. The shaft unit can include a shaft and a shaft head. In addition, a propeller unit can be arranged at the shaft, and the propeller unit can also be understood as a part of the drive unit.

[0051] According to a second aspect, the above-mentioned object is achieved by an outboard drive for a boat according to the invention. Advantageous developments emerge from the description and the accompanying drawings.

[0052] Accordingly, an outboard drive for a boat is proposed, comprising a fastening device for fastening the outboard drive to the boat and a drive unit which is arranged on the fastening device so as to be rotatable about a steering angle rotation axis.

[0053] The fastening device may be the fastening device described in the first aspect, but the fastening device is not limited thereto.

[0054] The fastening device and the drive unit are coupled via a setting component, which is used to set a steering angle range of the drive unit relative to the fastening device. In other words, the outboard drive comprises a setting component, by which a steering angle range of the drive unit relative to the fastening device can be set. By switching the setting component, at least three different steering angle ranges of the drive unit relative to the fastening device can be set.

[0055] Correspondingly, it is possible to predetermine the maximum possible steering angle, i.e. the maximum possible steering angle of the deviation of the orientation of the drive unit, more precisely the orientation of the propeller axis of the propeller of the drive unit, from the longitudinal direction of the ship, in a state in which the outboard drive is fastened to the ship as required, in a variably predefined manner. Here, the longitudinal direction is a steering angle of 0°. Therefore, each deviation from the orientation in the longitudinal direction corresponds to a steering angle swing, in which the steering angle between the propeller axis in the longitudinal direction and the propeller axis in the deflected state is specified. For example, a steering angle of ±60° means that the drive unit can be rotated about the steering angle rotation axis from an orientation of 0° in the longitudinal direction in a first direction, for example toward the starboard side, by 60°, and can also be rotated in a direction opposite to the first direction, according to the example toward the port side, by 60°.

[0056] By limiting the maximum possible steering angle swing, the safety of the use of a boat with an outboard drive can be increased in accordance with the type of boat used in each case on which the outboard drive is mounted, compared to conventional outboard drives. For example, by limiting the steering angle range, it is possible to prevent parts of the outboard drive, such as the propeller unit, from colliding with other parts of the boat, thereby causing damage to the outboard drive and / or the boat. Furthermore, it is possible to prevent the tiller from being turned into an area that cannot be reached safely and / or only with difficulty by an operator in the boat, such as towards the stern or even beyond the stern of the boat, when using an outboard drive with a tiller that can predetermine the direction and the speed level.

[0057] The limitation of the steering angle range can also be used advantageously for transport purposes of the outboard drive and / or the boat, in particular when the steering angle swing is limited to a few degrees or even locked to 0°.

[0058] Limiting to 0° can also be advantageous when the outboard motor is used to drive a boat which is already controlled individually, for example via a rudder, such as a rudder slider in a sailboat. In this case, the outboard motor can be set to have a steering angle swing of 0° and the sailboat can be controlled as usual via the rudder device.

[0059] In addition, the outboard drive can be used in different boat types without requiring significant adaptation of the boat and / or the outboard drive. For example, different steering angle ranges can be set for different boat types. For example, a first steering angle range can be set for a small to medium-sized boat, such as an aluminum boat or a bass boat. The first steering angle range can include, but is not limited to, ±60°. Another steering angle range can be designed for a rubber boat and, for example, include ±30°.

[0060] The outboard drive or the setting component can be optionally configured so that the setting component can be changed between at least three preset setting positions. In other words, the setting component can be arranged at the outboard drive so that its position can be alternatively moved to at least three preset setting positions relative to the fastening device and / or the drive unit, i.e., it can be changed between the setting positions. Here, in each of the preset setting positions, the steering angle range of the drive unit relative to the fastening device can be preset respectively. Therefore, each setting position presets the steering angle range of the preset parameter respectively.

[0061] Furthermore, the setting component can be arranged at the fastening device and / or the drive unit, i.e., for example, either at the fastening device or at the drive unit, and can be moved relative thereto into at least three setting positions. Optionally, the setting component can have a coupling section, with which the setting component can be coupled to a receiving section arranged at a corresponding other in the fastening device or the drive unit for at least one of the preset steering angle ranges. Thus, the setting component can be arranged at the fastening device or the drive unit, so that the setting component is coupled in at least one setting position with another in the fastening device or the drive unit, on which the setting component is not arranged, in order to realize and / or limit the preset steering angle range.

[0062] According to one embodiment, the setting component can be placed in a first setting position, in which the setting component is coupled to the first accommodating section, thereby presetting a first steering angle range. In addition, the setting component can be placed in a second setting position, in which the setting component is coupled to the second accommodating section, thereby presetting a second steering angle range different from the first steering angle range. In addition, the setting component can be placed in another, for example, a third setting position, in which the setting component is coupled to the third accommodating section, thereby presetting a third steering angle range. The setting component can also be configured to be placed in a release setting position, in which the setting component does not cause a steering angle restriction of the drive unit relative to the fastening device, thereby releasing the rotation of the drive unit relative to the fastening device, i.e., achieving a 360° rotation.

[0063] It has proven to be advantageous if one of the steering angle ranges has a rotation angle of 0°. Alternatively or additionally, at least one of the steering angle ranges can have a preset rotation angle greater than 0° and less than ±360°, optionally less than or equal to ±270°, further optionally less than or equal to ±180°, for example ±30°, ±45° or ±60°. One of the steering angle ranges can also correspond to a free rotation of the drive unit relative to the fastening device.

[0064] According to a third aspect, the above-mentioned object is achieved by an outboard drive for a boat according to the invention. Advantageous developments emerge from the description and the accompanying drawings.

[0065] Accordingly, an outboard drive for a boat is proposed, comprising a fastening device for fastening the outboard drive to the boat and a drive unit which is arranged on the fastening device so as to be rotatable about a steering angle rotation axis.

[0066] The fastening device may be the fastening device described in relation to the first aspect and / or in relation to the second aspect, but the fastening device is not limited thereto. The outboard drive may also be constructed according to one or more of the other aspects described in the disclosure.

[0067] According to this aspect, the outboard drive can be switched between a tiller steering mode and a remote control steering mode.

[0068] More specifically, the outboard drive may be configured such that the drive unit is switchable between a tiller steering mode and a remote control steering mode, or the drive unit and the fastening device are switchable between a tiller steering mode and a remote control steering mode.

[0069] In the tiller steering mode or equivalently in the tiller steering configuration, the tiller is attached to the drive unit. In this configuration, the control commands, ie the specification of the steering angle and optionally the specification of the driving speed stage, are specified by the operator via the tiller.

[0070] In the remote control steering mode or equivalently in the remote control steering configuration, the outboard drive is designed so that the control commands, i.e. the presetting of the steering angle and optionally the presetting of the travel speed level, are presetting from another point in the boat than the outboard drive, thus remote from the outboard drive and precisely not via the tiller. The control commands can be presetting, for example, via a control wheel connected to the drive unit. The travel speed level can be presetting for the outboard drive, more precisely the drive unit, via a travel speed level setting device connected to the drive unit, which is arranged, for example, next to the control wheel in the boat.

[0071] According to one embodiment, the drive unit may comprise a shaft which is rotatable about a steering angle rotation axis relative to the fastening device, wherein in the tiller steering mode the tiller rests on a shaft head of the shaft.

[0072] Alternatively or additionally, in remote-controlled steering mode, the control flange can be arranged on the shaft head.

[0073] Thus, in the tiller steering mode, the tiller can be arranged at the drive unit, and in the remote control steering mode, instead of the tiller, the control flange can be fastened in the tiller receiving portion of the shaft head. Therefore, in order to switch from the tiller steering mode to the remote control steering mode, it can be provided that the tiller is removed and the control flange is installed instead of the tiller.

[0074] Alternatively, it can be provided that the control flange is permanently arranged at the drive unit. In the tiller steering mode, the tiller steering mode is then advantageously decoupled from the remote control device, so that control commands cannot be transmitted to the drive unit via the control flange. In the remote control steering mode, the control flange is then connected to at least one remote control device, for example a control wheel arranged elsewhere in the ship, so that control commands can be transmitted to the drive unit via the control flange.

[0075] It is also possible to propose that the tiller arm is permanently arranged at the drive unit. Then, as mentioned above, the switch is only carried out by coupling or decoupling the control flange.

[0076] According to one embodiment, the control flange may include a coupling for coupling to a steering angle preset unit of an outboard drive, wherein optionally, the steering angle preset unit includes a steering rod connected to the control flange, wherein the steering rod can be moved relative to the fastening device along a transverse direction oriented perpendicular to the longitudinal direction, wherein the longitudinal direction corresponds to the longitudinal direction of the ship when the outboard drive is fastened to the ship by means of the fastening device in a state of prescribed fastening.

[0077] The steering rod can optionally be connected to the control flange via a push rod. In addition, the steering rod can be guided at the fastening device. Therefore, the connection to the remote control device of the ship can be realized in a simple manner.

[0078] According to one embodiment, the fastening device may comprise a fastening unit configured for fastening the outboard drive to the boat, and a swing unit that can be pivoted about the fastening unit about a preset transverse axis, the swing unit being configured for holding the drive unit, such as the fastening unit and the swing unit described with respect to the first aspect. The steering rod may optionally be guided centrally relative to the transverse axis of the swing unit, optionally in at least one hollow shaft defining the transverse axis.

[0079] The fastening device may comprise features of the fastening device according to the first aspect and / or the second aspect and / or the third aspect, but is not limited thereto.

[0080] According to a fourth aspect, the above-mentioned object is achieved by an outboard drive for a boat according to the invention. Advantageous developments emerge from the description and the accompanying drawings.

[0081] Correspondingly, an outboard drive for a boat is proposed, the outboard drive comprising a fastening device for fastening the outboard drive to the boat and a drive unit comprising a shaft, the drive unit being arranged at the fastening device in a manner rotatable around a steering angle rotation axis via the shaft, wherein the drive unit comprises a tiller arranged at the drive unit in a manner pivotable around a pivot axis, for example, at the shaft head of the shaft.

[0082] The fastening device may be the fastening device described in relation to the first aspect and / or the second aspect and / or the third aspect, but the fastening device is not limited thereto. The outboard drive may also be constructed according to one or more of the other aspects described in the disclosure.

[0083] The tiller is arranged on the drive unit in such a way that it can be switched between a normal position provided for operating the outboard drive and a transport position provided for transporting the outboard drive. In the normal position, the tiller is prevented from pivoting toward the fastening device, and in the transport position, the tiller is tilted toward the fastening device and held in the fastening device, so that the drive unit is prevented from rotating about the axis of rotation.

[0084] In order to transport the outboard drive, the outboard drive can therefore be turned over in a simple manner. More precisely, as described above, the tiller is moved from its normal position, in which it protrudes from the rest of the outboard drive, into a transport position in which it rests tightly against the rest of the outboard drive, in particular the shaft. The overall dimensions of the outboard drive are therefore smaller than during normal operation. The handling of the outboard drive is correspondingly simplified. This is because the tiller, which protrudes transversely to the shaft during normal operation, does not interfere with the movement and storage of the outboard drive, and an accidental turning over of the drive unit about the axis of rotation is not possible.

[0085] Furthermore, the outboard drive can be stored on the boat in a space-saving manner when it is not in use in the folded transport position.

[0086] According to one embodiment, the tiller arm can be located in the transport position folded between the two transom retaining arms of the fastening device.

[0087] Furthermore, a locking component may be provided at the drive unit, for example at the shaft head of the shaft, for selectively locking the tiller arm against pivoting towards the fastening device and releasing the tiller arm for a pivoting movement into the parking position.

[0088] The locking part can optionally be designed to be convertible, for example pivotable and / or movable, between a locking position and a release position, wherein in the locking position the locking part locks the tiller handle in a normal position against pivoting towards the fastening device, i.e. prohibits such pivoting, and in the release position a pivoting movement of the tiller handle into the parking position is enabled.

[0089] The locking elements can be preloaded together so that when the tiller arm is tilted to the horizontal, the tiller arm is automatically locked by the locking elements.

[0090] According to one embodiment, the tiller arm is arranged above the fastening device when viewed in the height direction. Pivoting the tiller arm towards the fastening device means pivoting downwards, ie towards the hull, when the outboard drive is properly fastened to the ship.

[0091] Pivoting towards the fastening device may be understood as pivoting in a first pivoting direction.

[0092] According to one embodiment, the locking component can be designed so that when the starting torque acting on the tiller arm is exceeded, the tiller arm can be pivoted from the normal position along a pivot direction pointing opposite to the fastening device to a second pivot direction opposite to the first pivot direction.

[0093] In order to enable comfortable operation of the tiller handle, for example when standing or by operators of different heights, the pivot position of the tiller handle can be set relative to the drive unit, more precisely relative to the shaft unit. In order to keep the tiller handle in a fixed pivot position, a brake unit can be provided for braking the pivoting movement of the tiller handle about the pivot axis relative to the drive unit, wherein the brake unit optionally applies a predefined clamping force to a pivot axis element defining the pivot axis or to a mechanical pivot axis element, wherein the amount of the clamping force can optionally be adjusted by an adjustment component, such as an adjustment screw, which is optionally accessible from the outside.

[0094] Thus, in particular, when standing, the driving comfort of the vehicle can be increased. In addition, the tiller can be kept in the transport position. BRIEF DESCRIPTION OF THE DRAWINGS

[0113] Advantageous exemplary embodiments are described below with reference to the drawings. Identical, similar or identically acting elements in different figures are provided with the same reference numerals, and a repeated description of the elements is partially omitted in order to avoid redundancy.

[0114] exist Figure 1 , a schematic cross-sectional view of a ship 1 is shown perpendicular to the transverse direction of the ship 1, which extends from the starboard side to the port side. The transverse direction is therefore perpendicular to the longitudinal direction L of the ship 1, which extends from the bow to the stern. The transverse direction and the longitudinal direction L are substantially parallel to the water surface or perpendicular to the gravity direction g in the static position of the ship 1 in the water, which is indicated here by the waterline W. In the disclosure, the height direction H of the ship 1 extends from the hull 2 ​​to the ship deck, i.e., opposite to the gravity direction g.

[0115] An outboard drive 100-400 is arranged on the stern side at the stern cover 3 of the ship 1, and the outboard drive 100-400 is, for example, an outboard drive according to one of the above-mentioned aspects, a combination of at least two of the aspects and / or an outboard drive 100-400 according to one of the following figures.

[0116] The outboard drive 100-400 comprises a fastening device 10 which is fastened to the transom 3 via a transom holder 11. The transom holder 11 is shown here by way of example in the form of a clamp. The drive unit 50 is supported at the fastening device 10 so as to be rotatable about a (steering angle) rotation axis 51 relative to the fastening device 10. The rotation axis 51 is oriented in the height direction H in the described position of the outboard drive 100-400, but is not limited thereto.

[0117] The drive unit 50 comprises a shaft unit 60, which has a shaft 61 and a shaft head 62. The propeller unit 52 is arranged relative to the shaft head 62, that is, arranged at the lower side of the shaft 61. The propeller unit 52 may include a motor (not shown), which is connected to a propeller 54 of the propeller unit 52 that can rotate around a propeller axis 55. Alternatively, the motor may be arranged at the shaft head 62 and connected to the propeller 54 via a force transmission unit extending in the shaft 61, such as a chain or belt drive and / or a gear drive. The outboard drive 100-400 may include a main energy unit for providing the energy required for driving the propeller 54. As shown here by way of example, the main energy unit may be a battery 53, which may be optionally arranged at the shaft head 62. Alternatively, the outboard drive 100-400 may also include a connection device, such as a current cable or a fuel hose, which may be connected to the main energy unit arranged in the ship 1.

[0118] Four exemplary embodiments 100-400 of outboard drives are described in more detail below. For greater clarity, the described components of the outboard drives are preceded by a "1" in the first embodiment 100, by a "2" in the second embodiment 200, by a "3" in the third embodiment 300, and by a "4" in the fourth embodiment 400, in order to consider the various aspects of the outboard drives 100-400 and their fastening device 10 in more detail. The features described for the various aspects can also be combined in the outboard drive, in particular.

[0119] Figure 2 and Figure 3Schematically, a three-dimensional side view of a fastening device 110 is shown, as it can be arranged according to Figure 1 Thus, the fastening device is a component of the outboard drive 100 according to the exemplary first embodiment.

[0120] The fastening device 110 is configured to fasten the outboard drive 100 to the boat 1. The fastening device comprises a fastening unit 113, which is configured to fasten the fastening device 110 and thus the outboard drive 100 to the boat 1. The fastening device also comprises a swing unit 112 which can be pivoted about the fastening unit 113 about a predetermined transverse axis Q, and which is configured to hold the shaft unit 160 (see Figure 1 ). The shaft unit 160 is supported on the pivot unit 112 so as to be rotatable about the axis of rotation 151 relative to the pivot unit 112 .

[0121] The trim position of the outboard drive 100 is currently adjustable so that the best possible orientation of the propeller unit 152, more precisely the propeller axis 155, as close to 0° as possible relative to the water surface can be achieved in different ships 1, which have different inclinations of the ship's transom 3 relative to the horizontal plane. For this purpose, the fastening unit 113 includes a plurality of trimming holes 115, into which trimming pins 116 can be inserted. The swivel unit 112 rests on the trimming pins 116 in the trimming position. By selecting the trimming holes 115, the position of the swivel unit 112 relative to the fastening unit 113 can be adapted in order to achieve an optimal orientation of the propeller axis 155 in the trimming position.

[0122] A lever unit 104 is arranged on the pivot unit 112 , via which the pivot unit 112 can be positioned alternatively in one of a plurality of different pivot positions relative to the fastening unit 113 .

[0123] On the one hand, the swivel unit 112 can be positioned via the lever unit 104 in the previously described trimming position, as will be described later with regard to Figure 5 and Figure 6 As described in more detail.

[0124] In addition, as in Figures 7 to 9 As shown in FIG. 1 , the pivot unit 112 can be positioned relative to the fastening unit 113 via the lever unit 104 in a plurality of, in the present case four, different shallow water positions.

[0125] Furthermore, in the exemplary embodiment described, for example, Fig.10As can be seen in FIG. 1 , the pivot unit 112 can be positioned in two different inclined positions relative to the fastening unit 113 via the lever unit 104 .

[0126] In order to operate the lever unit 104 , it comprises a handle 140 which can be manipulated by hand.

[0127] Figure 4 Schematically shows Figure 2 1. A perspective side view of the fastening device 110 in FIG. 1, wherein the covering element of the stern side of the swing unit 112 is omitted for a better view of the interior of the fastening device 110. Figure 5 Show Figures 1 to 4 sectional view of a fastening device 110.

[0128] According to the optional embodiment, the lever unit 104 comprises two lever members 141, 142. The first lever member 141 is pivotally arranged at the swing unit 112 via a pivotable joint 148 at one side. At the other side of the first lever member 141, the first lever member 141 is pivotally connected to the second lever member 142 via a pivotable joint 143. The second lever member 142 is guided at the swing unit 112 via a slide guide 145 at a distance from the pivotable joint 148. The slide guide 145 is currently implemented in the second lever member 142 in the form of a groove extending along a preset guide rail, in which a guide pin 146 arranged at the swing unit 112 is guided.

[0129] The lever unit 104 further comprises a preload mechanism for preloading the lever unit 104 in a predetermined direction. The preload mechanism is currently formed by a preload spring 144 arranged around a pivotable joint 148, which is supported on the pivot unit 112 and preloads the first lever member 141 toward the trimming bolt 116 in the rotational direction D1.

[0130] exist Figure 4 and Figure 5 , the swivel unit 112 is positioned in the trimming position. In this position, the swivel unit 112 is supported on the trimming bolt 116 on the stern side of the trimming bolt 116 with the support area 194. Thus, when traveling forward, the swivel unit 112 can be supported against the trimming bolt 116 and the propulsion force generated via the propeller unit 152 can be transmitted via the trimming bolt 116 (and also via the transverse axis Q or a support forming the transverse axis) to the fastening unit 113 and thus further to the ship 1.

[0131] exist Figure 5In the embodiment of the present invention, the lever unit 104 is switched into a locking position in which the lever unit 104 fixes the swivel unit 112 relative to the fastening unit 113 against pivoting out of the trimming position. More specifically, when the lever unit 104 is switched into the locking position, the swivel unit 112 is fixed at the trimming bolt 116 via the lever unit 104. For this purpose, the lever unit 104 comprises a locking stop 195 which, in the locking position of the lever unit 104, stops on the trimming bolt 116 on the bow side, i.e. substantially relative to the support area 194 of the swivel unit 112. Correspondingly, the swivel unit 112 does not swivel in the first pivoting direction S1, i.e. on the bow direction side, nor opposite to the first pivoting direction S1, i.e. on the stern direction side. Thus, in the position forward travel and backward travel can be provided.

[0132] The lever unit 104 is preloaded to the position where the lever unit 104 is preloaded by the preload spring 144. Figure 5 In the position shown in . The guide pin 146 is located approximately centrally in the slot guide 145 .

[0133] exist Figure 6 In the cross-sectional view of the fastening device 110 shown in FIG. 1 , the lever unit 104 is switched into the collision protection position, in which the lever unit 104 is configured to release the stern-side pivoting of the pivot unit 112. To this end, the lever unit 104, more precisely the locking stop 195, is disengaged from the trimming bolt 116 on the bow side of the trimming bolt 116 in the collision protection position. Therefore, the lever unit 104 is not prevented from pivoting the pivot unit 112 in the second pivoting direction S2, i.e., the stern-side.

[0134] In order to provide crash protection permanently, the lever unit 104 can be locked in the crash protection position. For this purpose, a locking receptacle 147 is provided at the lower end of the slide guide 145 for receiving a guide element 146 guided in the slide guide 145. If the guide element 146 is received in the locking receptacle 147, the lever unit 104 is locked in the crash protection position. The preload spring 144 preloads the lever unit 104 into the crash protection position.

[0135] Thus, in the trimming position, the lever unit 104 can be switched into a locking position in which the pivot unit 112 is fixed to the trimming bolt 116 , ie in the trimming position, so that the boat can be moved forward and backward.

[0136] In the trimming position, the lever unit 104 can alternatively be switched into a crash protection position in which the swivel unit 112 can be supported on the trimming bolt in a first pivot direction S1 and the swivel unit 112 can be pivoted in a second pivot direction S2 because the lever unit does not engage with the trimming bolt 116 on the bow-direction side thereof. This allows forward travel and crash protection to be provided.

[0137] As from Figures 4 to 10 As can be seen in the drawings, the fastening unit 113 includes a plurality of shallow water locking element receptacles 118 and a plurality of inclined locking element receptacles 117 which are arranged spaced apart from each other.

[0138] Each shallow water locking element receiving portion 118 presets a shallow water position of the swing unit 112 , and each tilt locking element receiving portion 117 presets a tilted position, ie, an above-water position, of the swing unit 112 .

[0139] The lever unit 104 comprises at least one locking element 143, which is designed in the form of a bolt, and which is also a bearing axis, via which the first lever component 141 and the second lever component 142 are pivotably supported relative to each other. The lever unit 104 is designed to be switched into a locking position, in which it engages with the locking element 143 in one of the shallow water locking element receptacles 118 or in one of the inclined locking element receptacles.

[0140] exist Figure 7 In the sectional view shown in FIG. 1 , the lever unit 104 is switched into a locked position in which it engages via a locking element 143 in a shallow-water locking element receptacle 118 provided on the fastening unit 113 .

[0141] exist Figure 8 The sectional view shown in FIG. 1 is at the height of the shallow water locking element receptacle 118, so that the engagement between the locking element 143 and the shallow water locking element receptacle 118 can be seen. The locking element 143 is supported on the shallow water locking element receptacle 118, in particular in the first pivot direction S1. The swivel unit 112 is in turn supported on the locking element 143 via the support section 119, so that the remaining bearings of the lever unit 104 are at least partially unloaded. Therefore, the force flow from the swivel unit 112 to the fastening unit 113 at least partially enters directly from the swivel unit 112 via the locking element 143 into the fastening unit 113.

[0142] The lever unit 104 with its locking element 143 is preloaded into the shallow water locking element receptacle 118 by means of a preload spring 144 .

[0143] Figure 7 and Figure 8 The position shown in corresponds to the shallow water position of the swing unit 112, where Figures 2 to 6 As shown in FIG. 1 , the rotation axis 51 is inclined by 40° relative to its orientation in the lowermost dressing position.

[0144] The two shallow water locking accommodating parts 118 arranged below the shallow water locking element accommodating part 118 give the swing unit 112 a forward inclination of 20° and 30°, and the shallow water locking accommodating part 118 arranged above it gives a 50° inclination, but is not limited thereto. Figure 8 The locking element 143 is engaged with the locking element 143.

[0145] In the fastening device 110 Fig. 9 In the cross-sectional view shown in FIG. 1 , the locking element 143 engages with the lowermost of the shallow water locking element receptacles 118 , so that the swing unit 112 is positioned at an inclination of 20° relative to the trim position.

[0146] Fig.10 The fastening device 110 is shown in a sectional view, wherein the swivel unit 112 is positioned in the upper of the two tilted positions. Figures 2 to 6 The trim position showing the 0° position is pivoted upwards by 90°, ie, sideways in the stern direction.

[0147] Similar to the shallow water position, the swivel unit 112 is supported on the locking bolt 143 via the support section 119 and supported on the tilting locking element receiving portion 117 via the locking bolt. The lever unit 104 is located in the locking position or switched to the locking position. The preload spring 144 preloads the lever unit 104 into the tilting locking element receiving portion 117.

[0148] The shallow water locking element receptacle 118 and the lower tilting locking element receptacle 117 are designed so that when the outboard drive 100 is fastened to the boat 1 by means of the fastening device 110 in a properly fastened state, when the resulting pivoting moment Mr (see Figure 7) exceeds a preset threshold value, the swivel unit 112 can be pivoted on the stern side, i.e. in the second pivot direction S2. This is achieved according to the exemplary embodiment by the fact that the shallow water locking element receptacle 118 and the lower inclined locking element receptacle 117 each comprise an inclined ramp 149 oriented at a preset angle to a tangent to the circumferential direction with respect to the transverse axis Q on the stern side. If the external moment applied to the swivel unit 112 in the second pivot direction S2 exceeds a preset threshold value, which is composed of a moment component due to the weight of the swivel unit 112 and a moment component due to the preload achieved by the preload spring 144, the locking element 143 slides onto the ramp 149 in the second pivot direction S2 via the ramp 149 at least toward the following locking element receptacles 117, 118. Thus, collision protection is also provided in the shallow water position and impact damage protection is provided in the lower inclined position.

[0149] Fig.11 A perspective view of an outboard drive 200 according to another embodiment is schematically shown.

[0150] The outboard drive device 200 includes a fastening device 210, which may be, for example, the fastening device 110 according to the above-described first embodiment, but is not limited thereto.

[0151] Furthermore, the outboard drive 200 includes a drive unit 250, which is arranged at the fastening device 210 in a manner that it can rotate around a steering angle rotation axis 251. The fastening device 210 and the drive unit 250 are configured in a manner that they are coupled to each other via a setting component 270, which is used to set the steering angle range of the drive unit 250. By switching the setting component 270, at least three different steering angle ranges of the drive unit 250 relative to the fastening device 210 can be set.

[0152] To this end, the setting component 270 can be switched between three currently preset setting positions, wherein the setting positions are Figure 12 to Figure 14 It is shown in Figure 12 to Figure 14 Schematically show the Fig.11 A cross-sectional view through the outboard drive 200.

[0153] In each of the preset setting positions of the setting component 270 , a different steering angle range of the drive unit 250 , more precisely the shaft 261 and thus the propeller unit 252 relative to the fastening device 210 is preset.

[0154] According to the embodiment, the setting part 270 is arranged on the fastening device 210 and in two of the three aforementioned setting positions cooperates with the associated receiving sections 273, 274 on the shaft head 262. For this purpose, the setting part 270 comprises a coupling section 272, which is designed as a cylindrical pin, for example, in the present case, by means of which the setting part can be coupled to the receiving sections 273, 274 for respectively presetting the steering angle range.

[0155] In order to preset the steering angle and the travel speed level, the outboard motor 200 here optionally includes a tiller 220, which is arranged at the shaft head 262. At the rear side, the shaft head 262 optionally includes a battery holder for accommodating the battery unit 253 (see Figure 1 ).

[0156] exist Figure 3 , the setting component 270 is arranged in a second (middle) setting position, and the upper and lower setting positions are also identified in a marked manner.

[0157] In a first (upper) setting position, the setting element 270 can be coupled to the first receiving section 274 , whereby a first steering angle range is predetermined.

[0158] As is currently the case here, the first receiving section 274 can be designed as a hole and the first steering angle range is 0°. In other words, the first steering angle range can optionally be limited to 0° here. The drive unit 250 or the shaft 261 is thus locked in a fixed position. As is currently the case here, this can be a lock in the longitudinal direction L. The drive unit 250 is thereby locked in the straight-ahead position. This position can be advantageous, for example, for the transport of the boat 1 and / or the outboard drive 200. In addition, this position can be selected when the steering movement of the boat 1 is not to be preset via the steering angle position of the drive unit 250, but rather via a separate mechanism, such as the rudder of the boat 1.

[0159] exist Fig.13 , the setting component 270 is arranged in a second (middle) setting position, in which it moves downward by a predetermined amount in the direction of the rotation axis 251 relative to the upper setting position, so that the setting component 270 is coupled to the second receiving section 274. Thus, a second steering angle range of the drive unit 250 relative to the fastening device 210, more precisely relative to the swivel unit 212, is predetermined.

[0160] The steering angle range is preset to ±60°, for example, relative to the longitudinal direction L representing the straight-ahead position. Thus, from a lateral end stop 277 of the second receiving section 274 to the opposite end stop 277 (see Figure 6 )'s total possible steering angle is 120°.

[0161] exist Fig.14 , the setting component 270 is arranged in a third (lower) setting position, in which the setting component moves downward by another preset amount in the direction of the rotation axis 251 relative to the first setting position or the second setting position, so that the setting component 270 is not coupled with any of the accommodating sections 273, 274, thereby presetting a third steering angle range. The third setting position is a release setting position, in which the setting component 270 does not cause a steering angle limitation of the drive unit 250 relative to the fastening device 210.

[0162] exist Fig.15 2 shows a view from below, ie in the direction of the axis of rotation 251, onto the shaft head 262. This results in a first steering angle range 275 and a second steering angle range 276.

[0163] Fig.16 and Fig.17 A perspective view of an outboard drive 300 according to another embodiment is schematically shown. The outboard drive substantially corresponds to the outboard drives 100, 200 according to the first and second embodiments, but is not limited thereto.

[0164] The outboard drive 300 comprises a fastening device 310 for fastening the outboard drive 300 to the boat 1 and a drive unit 350 which is arranged at the fastening device 310 in a rotatable manner about the steering angle rotation axis 251 .

[0165] The outboard drive 300 can be in a tiller steering mode (see Fig.16 ) and remote control steering mode (see Fig.17 )

[0166] In tiller steering mode or equivalently in tiller steering configuration, such as from Fig.16 As can be seen in the configuration, the tiller handle 320 is arranged at the shaft head 362 of the shaft 361 arranged on the fastening device 310 so as to be rotatable about the fastening device 310, in the tiller handle receptacle 321 arranged at the shaft head 362, on the front side of the shaft head 362, i.e., on the side pointing toward the bow when fastened to the ship 1 as required. The steering movement of the drive unit 350 and the driving speed level formed by the rotation speed of the propeller 354 are preset by the operator directly via the tiller handle 320 in this configuration.

[0167] As will be described further in the following embodiments, the tiller arm 320 may be arranged at the shaft head 362 so as to be pivotable about a pivot axis 322 relative to the shaft head 362 .

[0168] exist Fig.17 In the figures, the outboard drive 300 is shown in a remote-controlled steering mode or in a remote-controlled steering configuration, respectively, wherein a control flange 323 is arranged at the shaft head 362 instead of the tiller 320 in the tiller receptacle 321. The tiller receptacle 321 is optionally covered by a cover 324.

[0169] The control flange 323 comprises a coupling element 325 for coupling to a steering angle presetting unit 330. The steering angle presetting unit 330 comprises a steering rod 331 connected to the control flange 323 via a push rod 332, which can be moved relative to the fastening device 310 in a transverse direction Q oriented perpendicularly to the longitudinal direction L, which corresponds to the longitudinal direction of the ship when the outboard drive 300 is fastened to the ship 1 by means of the fastening device 310 in a state of being fastened in accordance with the regulations, wherein the steering rod 331 is optionally guided at the fastening device 310.

[0170] Similar to the first embodiment, the fastening device 311 includes a swing unit 312 configured to hold the driving unit 350 , which can be pivoted about a predetermined transverse axis Q relative to the fastening unit 312 including the tail plate holder 311 .

[0171] As shown here, the deflection rod 331 can be guided centrally relative to a predefined transverse axis Q. In the present case, this is achieved by guiding the deflection rod 331 in a hollow shaft 335 which defines the transverse axis Q.

[0172] Fig.18 Another perspective side view of an outboard drive 300 is schematically shown in a partially exploded view. Fig.19 The drive unit 350 is shown without the cover 324 in order to illustrate the fastening of the control flange 323 in the tiller receptacle 321 .

[0173] The control flange 323 is fastened in the tiller receiving portion 321 via a fastening element 333, which is optionally in the form of a screw, at a joint 325 provided for realizing the pivot axis 322 of the tiller 320. In addition, the control flange 323 is fastened to the tiller receiving portion 321 via a fastening element 333, which is optionally also in the form of a screw, at another joint 326 spaced apart from the joint 325, so that torque can be transmitted.

[0174] Fig.19 A perspective detailed view of the shaft head 362 together with the tiller handle receptacle 321 is shown, wherein the control flange 323 is fastened in the tiller handle receptacle 321 via the fastening element 333 .

[0175] As shown in the perspective view of the shaft head 362 from obliquely below Fig. 20It can be seen that the cover 324 is fastened to the control flange via fastening elements 335 , in the present case in the form of screws.

[0176] Fig.21 and Fig. 22 A perspective view of an outboard drive 400 according to another embodiment is schematically shown. The outboard drive substantially corresponds to the outboard drives 100, 200, 300 according to the previously described embodiments, but is not limited thereto.

[0177] The outboard drive 400 comprises a fastening device 410 for fastening the outboard drive to the boat 1 and a drive unit 450 comprising a shaft 461, which is arranged on the fastening device 410 in a manner that it can rotate around a steering angle rotation axis 451 via the shaft 461, wherein the drive unit 450 comprises a tiller handle 420, which is arranged on the drive unit 450 in a manner that it can pivot around a pivot axis 422, more precisely, it is pivotably arranged on the shaft head 462 of the shaft 461.

[0178] The tiller 420 can be switched between a normal position or equivalently an operating position, which is provided for operating the outboard drive 400, and a transport position, which is provided for transporting the outboard drive. In the normal position, the tiller 420 is prevented from pivoting about the pivot axis 422 towards the fastening device 410, i.e. towards the waterline W or the hull 2 ​​(see Figure 1 ) is pivoted. In other words, in the normal position in which the tiller 420 can have a set orientation, for example a substantially horizontal orientation and / or an orientation in which the tiller 420 is substantially perpendicular to the steering angle rotation axis 451, the tiller 420 is prevented from being lowered downwards, i.e. towards the lower side of the ship 1. In the transport position, the tiller 420 is flipped towards the fastening device 410 and is held in the fastening device, so that the drive unit 450 is prevented from a rotational movement about the steering angle rotation axis 541.

[0179] In the transport position, the tiller 420 can be turned between the two tail plate holding arms 414 of the fastening device 410. The width of the tiller 420 can be designed in such a way that it corresponds to the opening existing between the tail plate holding arms 414 in the region of the tail plate holding arms 414. The tail plate holding arms 414 are thus lateral stops for the tiller 420. The drive unit 450 cannot be rotated about the steering angle rotation axis 451, but is fixed in a predefined position, here a zero position at a rotation angle of 0° relative to the longitudinal direction L.

[0180] At the drive unit 450 , a locking component 480 is provided according to the embodiment at the shaft head 462 of the shaft 461 , which locking component is configured for selectively locking the tiller arm 420 against pivoting towards the fastening device 410 and releasing the tiller arm for pivoting movement into a stop position.

[0181] Fig.23 and Fig.24 A schematic detail view of the area of ​​the outboard drive 400 in which the locking element 480 is provided is shown. Fig.23 In the embodiment of the present invention, the locking member 480 is positioned in a locking position in which the locking member 480 prevents the tiller arm 420 from pivoting toward the fastening device 410 in the normal position.

[0182] exist Fig.24 In the release position, the locking member 480 is changed from the locking position to the release position, in which the locking member 480 does not exert any locking effect on the tiller handle 420. Therefore, in the release position, the tiller handle 420 is pivotally moved from the normal position to the parking position.

[0183] exist Fig.25 Schematically, a simplified functional illustration of a tiller arm 420 and a locking component 480 which can be pivoted about a pivot axis 422 is shown in FIG. 4 , wherein the tiller arm 420 is in a normal position and the locking component 480 is in a locking position.

[0184] Fig.26 A simplified functional diagram of the tiller arm 420 and the locking member 480 is schematically shown, wherein the tiller arm 420 is in a normal position and the locking member 480 is in a released position.

[0185] The locking component 480 is configured as a lever, but is not limited thereto, and the lever can be pivoted around the locking component pivot axis 486 between the locking position and the release position. The locking component 480 can be preloaded toward the locking position by a preload unit not shown here, and the preload unit is, for example, in the form of a spring, such as a spiral spring, a pressure spring, a tension spring or a leaf spring, or in the form of a magnetic unit. Correspondingly, the locking component 480 is always committed to reaching the locking position, and can only be moved from the locking position to the release position by overcoming the preload force provided by the preload unit. In order to transform the locking component 480 from the locking position to the release position and / or from the release position to the locking position, the locking component 480 may include an operating unit, for example, in the form of a handle 485 shown here.

[0186] The locking part 480 comprises a contact area 488 which is formed at the tiller 420 corresponding to the contact area 487. In the locked position, the contact area 488 engages into the contact area 487 at the tiller 420 in order to provide locking.

[0187] According to this embodiment, the contact region 488 is formed on the locking part 480 by a stop 482, which in the locked position stops at a stop 481, which is a contact region 487 on the tiller handle 420. In addition, the locking part 480 comprises a contact surface 484, with which it contacts a correspondingly formed contact surface 483 on the tiller handle 420 in the locked position.

[0188] The locking element 480 can be selectively designed so that when a starting torque acting on the tiller arm 480 in the second pivoting direction is exceeded, the tiller arm 420 can be pivoted from the normal position in the second pivoting direction, i.e. upwards, which is opposite to the first pivoting direction pointing toward the fastening device 410. Alternatively or additionally, a brake unit can be provided for this purpose.

[0189] Fig. 27 A perspective detail view of the tiller handle 420 from below is schematically shown. Fig.28 Schematically shows Fig. 27 4. As can be seen from the figure, the outboard motor 400 comprises a brake unit 490 for braking the pivoting movement of the tiller handle 420 relative to the shaft head 462 about the pivot axis 422. The brake unit is designed, but not limited to, such that it applies a preset clamping force to the pivot axis 422, more precisely to the pivot axis element 427 which mechanically forms the geometric pivot axis 422. The level of the clamping force can be adjusted by an adjustment component that is accessible from the outside and is optionally designed as an adjustment screw 491.

[0190] The brake unit 490 comprises a bearing part 492 which at least partially forms part of the bearing arrangement of the tiller 420 around the pivot axis element 427, here the lower half. The bearing part 492 is fastened to the tiller 420 at a first side relative to the pivot axis 422 via at least one fastening screw 493, in the present case two fastening screws 493.

[0191] On a second side, opposite to the first side, the bearing part 492 is screwed onto the tiller 420 via an adjusting screw 491. By adjusting the position of the adjusting screw, the pressing or clamping force applied to the pivot axis element 427 by the bearing part 492 and the tiller 420 can be changed. The pressing or clamping force causes adhesion and friction forces between the radially inner contact surfaces of the tiller 420 and the bearing part 492 and the radially outer contact surfaces of the pivot axis element 427 on the one hand.

[0192] The brake unit 490 is therefore a parking brake which holds, ie fixes, the tiller arm 420 in a set position by means of a clamping force and, after overcoming the adhesion force, allows the tiller arm 420 to be pivoted against the friction force provided by the brake unit 490 .

[0193] Fig.29 and Fig.30 Show respectively according to Fig.12 An outboard drive 400 in which the tiller handle 420 is lifted from a normal position along a second pivot direction, i.e. upwards, to different positions, in which the tiller handle is respectively held, i.e. fixed, by a brake unit 490.

[0194] When the locking member 480 is positioned in the locking position, the tiller arm 420 may be lifted from the normal position along the second pivot direction to a preset maximum lifting angle, ie, a maximum lifting position.

[0195] The brake unit 490 also holds the tiller arm 420 in the parked position via friction or adhesion forces, thus fixing the tiller arm in the parked position and preventing the tiller arm from undesirably pivoting about the pivot axis 422 in the second direction, ie leaving the predefined parked position.

[0196] As far as applicable, all individual features shown in the exemplary embodiments may be combined with one another and / or interchanged without departing from the scope of the present invention.
