Description
AREA OF INVENTION
[0001] This invention relates to a mobile device for the maintenance of properties, for example gardens, meadows or agricultural land. In particular, the mobile device can be a lawnmower with a working tool, for example the cutting blade.
[0002] This invention further relates to a method for maintaining properties using such a mobile device. STATE OF THE ART
[0003] In the gardening industry and generally in the field of property maintenance, the use of mobile devices, e.g. lawn mowers, rotary tillers, aerators or the like, is known, which are operated and moved by hand or are self-propelled and designed to perform their functions to fully cover the work area.
[0004] During the work phases, some sections of the work area, such as the perimeter, boundary, or certain specific zones located in the center of the work area, may be particularly difficult to access effectively due to obstacles like hedges, flowerbeds, trees, or similar. These obstacles can make it difficult for the mobile device to reach some areas of the work area, resulting in lower work quality compared to more easily accessible areas.
[0005] Especially when the mobile device is moved manually, the operator may have difficulty moving the mobile device in the perimeter and boundary zones due to the aforementioned obstacles.
[0006] Furthermore, the dimensions of the mobile device in height and / or width may interfere with the aforementioned obstacles, such as a surrounding hedge, and thus prevent the proper processing of the perimeter or boundary zones.
[0007] Furthermore, the state-of-the-art adjustment systems of the operating handle of the mobile device, for example for height adjustment, tend to wear out quickly, especially when heavily used: once the adjustment system is worn out, the handle tends to “fall off” and proves in fact to be unusable for steering and controlling the mobile device.
[0008] Document DE8709285U1 describes a rail-mounted lawn mower whose frame can move laterally in the space between the rails. Document US5,771,672 describes a lawn mower in which the mowing deck can move laterally to the right and left with respect to the frame. Document EP3738424A1 describes a lawn mower comprising a mechanism for coupling the mowing deck to the frame, enabling the mowing deck to move laterally. Documents DE102004057043A1 and EP1791415A1 describe a lawn mower comprising two subassemblies that are rotatable relative to each other about a vertical axis, wherein the handlebar and cutting tool belong to the first subassembly and a pair of wheels belongs to the second subassembly. EP3466237A1 describes a lawn mower with a handle assembly, wherein the handle assembly comprises a coupling component and a handle segment that is rotatable with respect to the coupling component.Document AU462048B2 describes a lawn mower with a handle assembly, wherein the handle assembly comprises a lower section attached to the frame and an upper section that is rotatable so that it is movable laterally to the direction of travel of the lawn mower. Document US2011 / 0302893A1 describes a lawn mower with a handle rotatably connected to the frame and a tilt adjustment device inserted between the handle and the frame. Document DE4428373C1 describes a lawn mower whose handlebars can rotate relative to the frame and be locked in various tilt positions. Document EP3498073A1 describes a lawn mower whose handlebars are connected to the frame by a joint, wherein the joint comprises a handle mounting body, a pair of arms attached to the frame, and means for selectively locking the body relative to the arms.Document US2014 / 0290006A1 describes a lawn mower with a handlebar height adjustment mechanism, wherein the adjustment mechanism comprises a pair of toothed disc elements and a disc element for connection.

[0169] The left side 12 and the right side 13 can comprise the means of locomotion 3, in particular wheels or tracks for locomotion: For example, the left side 12 and the right side 13 of the mobile device 1 can each comprise two wheels on the front section 10 and the other on the rear section 11. In other words, the mobile device 1 can have a front axle 3a on the front section 10, comprising a left front wheel 3a' and a right front wheel 3a'', and a rear axle 3b on the rear section 11, comprising a left rear wheel 3b' and a right rear wheel 3b''.
[0170] An envelope of the four wheels, in particular an envelope defined by the front wheels left and right and by the rear wheels left and right, defines a circumferential line 7 of the mobile device 1.
[0171] The mobile device 1 extends lengthwise between the front section 10 and the rear section 11 to define a longitudinal axis X of the mobile device 1. In particular, the longitudinal axis X of the mobile device 1 intersects the front section 10 and the rear section 11 substantially at right angles. Specifically, the longitudinal axis X of the mobile device 1 can define an axis of symmetry between the left side 12 and the right side 13 of the mobile device 1 and pass through a central section of the mobile device 1. Likewise, a linear movement of the mobile device 1 can coincide with the longitudinal axis X of the mobile device 1. Furthermore, the longitudinal axis X can be arranged substantially at right angles to the front and / or rear wheel axis of the mobile device 1, at least during a linear movement state.Furthermore, the longitudinal axis X can be equidistant from the wheels to the left and right of the same axis: In this case, the longitudinal axis defines a central longitudinal axis of the mobile device. In particular, this description assumes that the longitudinal axis X is located in the center of the mobile device.
[0172] The means of movement 3 define a contact surface SP for the mobile device 1: This contact surface SP effectively coincides with the ground during an operating state of the mobile device 1. In particular, the contact surface extends through the contact points between the wheels of the mobile device 1 and the ground on which the mobile device 1 is positioned. It should be noted that the rotary cutter of the working tool 4 is movable about a rotational axis A that runs transversely or substantially perpendicular to the contact surface SP.
[0173] The means of motion 3 can also define a linear feed of the mobile device 1 along a longitudinal feed direction that essentially coincides with the longitudinal axis X of the mobile device 1: The longitudinal feed direction is, in particular, arranged essentially perpendicular to a rotation axis of the wheels of the mobile device 1. This longitudinal feed direction runs essentially parallel to the support surface SP: Accordingly, the longitudinal axis X runs parallel to the support surface SP.
[0174] The mobile device 1 extends lengthwise along a vertical axis Z, which is perpendicular to the longitudinal axis X and the support surface SP, defined by the means of movement 3. In other words, when the mobile device 1 is placed on the ground on its means of movement 3, the longitudinal axis X is perpendicular to the ground. The operating body 5 can be movable in height along the vertical axis Z between a position farther from and closer to the support surface SP: In particular, during an operating state, the operating body 5 can be movable in height along the vertical axis Z with respect to the ground between a position farther from and closer to the ground to allow for a variable cutting height.A change along the vertical axis Z of the operating body 5 causes a simultaneous change in the height of the working tool 4 and consequently a change in the distance between the working tool 4 and the ground and / or the support surface.
[0175] Accordingly, the mobile device 1 extends in width along a transverse axis W between a left side 12, which serves to connect the front section 10 and the rear section 11 of the mobile device 1, and a right side 13, which also serves to connect the front section 10 and the rear section 11 of the mobile device 1: The right side 13 is opposite to and spaced apart from the left side 12. In particular, the transverse axis W is perpendicular to the longitudinal axis X and the vertical axis Z.
[0176] In other words, the longitudinal axis X, the transverse axis W, and the vertical axis Z are defined according to the representation in Fig. 1. A reference system of the mobile device 1. The zero point of this reference system can be the center of mass or geometric center of gravity of the mobile device. According to this reference system, the axis of rotation A of the rotary encoder is substantially parallel to or coincides with the vertical axis Z of the mobile device 1.
[0177] One axle of the front and / or rear wheels runs parallel to the transverse axis W and optionally essentially parallel to the contact surface SP.
[0178] If the mobile device 1 is a hand-held device, it can be operated according to the illustrations in the Fig. Figures 1 to 5 comprise an operating handle 20, which is substantially attached to the rear section 11 of the mobile device 1 and is designed to allow an operator to guide and optionally move, for example, push, the mobile device 1 within the working area. The operating handle 20 can be made of a metal material, for example, steel, iron, or aluminum, or of a plastic or composite material. The operating handle 20 preferably extends along an oblique and transverse direction to the operating body 5, in particular transverse to the support surface SP. The operating handle 20 defines, in particular, an angle to the support surface SP between 20° and 70°, most especially between 30° and 50°. As shown in the illustrations in the Fig. 1 to 5, the handle extends from the rear of the mobile device 1 essentially from the rear section 11 between a first end connected to the rear section 11 of the mobile device 1 and a second end designed to allow gripping by an operator: Since the operating handle 20 is inclined towards the support surface, it defines in particular a horizontal projection onto the support surface, in other words onto the ground, and a vertical projection onto the vertical axis of the mobile device 1. The horizontal projection extends from the rear section 11 of the mobile device 1 along and towards a direction leading away from the rear section 11 of the mobile device 1.
[0179] According to any of the described and claimed embodiments, the handle can be attached directly to the operating body 5 of the mobile device 1 or to the support frame 2. In particular, the handle can be attached to a first and a second coupling point on the mobile device 1, for example a left and a right coupling point.
[0180] The operating handle 20 defines an instrument that the operator uses to push and / or guide the mobile device 1 within the work area.
[0181] The operator can also use the handle to lift at least part of the mobile device 1: For example, by lowering the handle and applying leverage to the rear wheels of the mobile device 1, the operator can lift the front wheels of the mobile device 1 and the operating body 5. Further details and embodiments of the handle are described below.
[0182] The operating body 5 defines a cover for the working tool 4, in particular the rotary blade: The operating body 5 covers the rotary blade at least laterally and on its upper side, while the underside of the operating body 5 is open to allow contact between the grass and the rotary blade. According to one embodiment, the operating body 5 has a circular or semicircular shape; alternatively, the operating body 5 can have a polygonal shape, for example, a rectangular or square one. In particular, the operating body 5 comprises an upper disc-shaped section that carries the motor and the corresponding working tool 4, for example, the rotary blade: The operating body 5 further comprises a side wall that projects transversely from the upper section, in particular from a circumferential zone of the upper section. The operating body 5 thus has a bell shape that defines an internal volume that accommodates the working tool 4.
[0183] The operating body 5 can be made of a metal material, for example steel or aluminum, or of a plastic or composite material. It should be noted that the operating body is rigidly attached to the working tool and the corresponding motor: Consequently, any movement of the operating surface will force a corresponding displacement of the working tool and the corresponding motor. In other words, the operating body and the working tool are rigidly connected: The only degree of freedom of the operating body with respect to the operating surface is the rotational degree of freedom about the axis of rotation A.
[0184] The mobile device 1 also includes a discharge line 14 designed to direct the mowed grass to a rear or side section of the mobile device 1 during operation: In particular, this discharge line 14 extends between a first end facing an outlet of the operating body 5 and a second end suitable for emptying the mowed grass and optionally being attached to a grass catcher.
[0185] In one embodiment, which is schematically shown in Fig. 11 and from below in Fig. As shown in Figure 23, the working tool 4 of the mobile device 1 comprises a first rotary cutter 4a, which is rotatably movable about a rotational axis A, and a second rotary cutter 4b, which is rotatably movable about an auxiliary rotational axis A'. The first and the second rotary cutter 4b are both supported by the same operating body 5 and are arranged side by side: In particular, the rotational axis A runs essentially parallel to the auxiliary rotational axis A' and is spaced apart from it. It should be noted that the rotational axis A and the auxiliary rotational axis A' can run essentially perpendicular to the support surface defined by the means of motion 3.
[0186] The first and second blades can have the same diameter or alternately different diameters, with the first rotary blade 4a, for example, having a smaller diameter than the second rotary blade 4b.
[0187] The first and second blades are preferably rotating in opposite directions, so that the cut grass is directed towards the discharge pipe: The term "rotating in opposite directions" indicates that the second blade rotates counterclockwise when the first blade rotates clockwise, and vice versa.
[0188] The operating body 5, which according to the embodiment comprises two rotary blades, can have an elongated shape and completely cover the two rotary blades: In particular, the operating body 5 can have an elongated circular shape at its side ends according to Fig. 11. According to the embodiment comprising two rotary blades, the mobile device 1 also includes a hose 13 extending between a first end, which is attached to a central section of the operating body 5, and a second end, which is attached to an inlet of the discharge line. The hose is thus positioned between the discharge line 14 and the operating body 5 and is designed to allow the passage of the cut grass to the discharge line, both when the operating body 5 is in the left-hand position and when it is in the right-hand position. The hose may have a bellows shape and be made of fabric or, alternatively, of plastic. SIDE-MOUNTED OPERATING HANDLE
[0189] In one embodiment, the hand-held mobile device 1 comprises the actuating handle 20 projecting from the rear of the mobile device 1 and a coupling element connected to the actuating handle 20 and designed to move at least a part of the actuating handle 20 along a steering axis D as shown in the illustrations in the Fig. 8A and Fig. 8B as well as the Fig. 14A and Fig. 14B in accordance with a further embodiment. It should be noted that the steering axis D comprises at least one translational component which runs substantially parallel to the transverse axis W: This means that the movement of the actuating handle 20 can still be carried out along a vertical axis or rotationally, although it includes a movement component parallel to the transverse axis W.
[0190] Moving the operating handle laterally allows the operator to avoid any obstacles along the path within the work area. For example, if the mobile device 1 is working near a hedge, the operator can move the operating handle 20 laterally away from the hedge while simultaneously keeping the mobile device 1 mowing alongside the hedge. In other words, this embodiment allows the operator to shift their position to easily reach difficult-to-access areas of the work area without compromising control of the mobile device 1.
[0191] In particular, the clutch assembly is designed to allow the positioning of the actuating handle 20 along the steering axis D as follows: - into a right-hand side position in which the operating handle 20 protrudes at least partially to the right in relation to the circumferential line 7; - into a left lateral position in which the operating handle 20 protrudes at least partially to the left in relation to the circumferential line 7; - into a central position, which is inserted between the right side position and the left side position.
[0192] The right and left side positions of the actuating handle 20 define the maximum end limits of its movement along the steering axis D. In particular, when the actuating handle 20 is in the left and / or right side position, it exceeds the lateral limit profiles defined by the moving means 3 of the mobile device 1. The maximum translation value of the actuating handle along the steering axis D, which is useful for moving the operating body 5, is between 5 cm and 50 cm relative to the center position.
[0193] In an embodiment not shown in the accompanying figures, the coupling element comprises a rail designed to move the actuating handle translationally along the steering axis 40: This translation is in particular a movement of the handle along a straight path and substantially perpendicular to the longitudinal axis X of the mobile device and optionally parallel to the translational axis Y of the operating body 5.
[0194] In another embodiment, the coupling element comprises a joint 40: The actuating handle 20 and the corresponding joint 40 are described in detail in the Fig. 6 and Fig. 7 in accordance with an embodiment in which Fig. 12 to 19 in accordance with a further embodiment and in Fig. 21 is shown in accordance with a further embodiment: The three embodiments differ essentially in the design of the joint 40. It should be noted that the embodiments allow the actuating handle 20 to be moved along the steering axis D, and consequently each of the embodiments contributes to achieving the same advantages described above with regard to the displacement of the handle along the D-axis. The actuating handle 20 comprises a first element 21 extending by a first length between a first end, which is attached to a rear section 11 of the mobile device 1, and a second end, which carries or comprises at least a first coupling element 42 of the joint 40.The actuating handle 20 also comprises a second element 22, which is movable with respect to and distinct from the first element 21 of the actuating handle 20 and extends by a second length between a first end, which includes or carries a second coupling element 43 of the joint 40, which is non-removably attached to the second end of the first element 21 of the actuating handle 20, and a second end, which includes a gripping section 22a designed to be gripped by an operator while guiding the mobile device 1.
[0195] In particular, the first member 21 of the actuating handle 20 comprises a first coupling section 21a, designed to attach to the rear of the mobile device 1 and extending laterally to the right side 13 of the mobile device 1, and a second coupling section 21b, designed to attach to the rear of the mobile device 1 and extending laterally to the left side 12 of the mobile device 1. The second coupling section 21b is distinct from the first coupling section 21a and spaced apart from it along the transverse axis W. The first member 21 further comprises a first section 21c extending between the first coupling section 21a and the joint 40, and a second section 21d extending between the second coupling section 21b and the joint 40.In other words, the first and second sections 21c, 21d of the first link 21 of the actuating handle 20 meet in the middle of the joint 40: It should be noted that the actuating handle comprises only a single joint 40 which attaches the first link 21 to the second link 22 of the actuating handle 20.
[0196] The first and second sections 21d are combined to define a first link 21 of the actuating handle 20 in a single body: This single body comprises the first coupling section 21a, the first section 21c, the second section 21d, and the second coupling section 21b: In particular, the first link 21 has a U-shaped bend with a cavity facing the rear section 11 of the mobile device 1. The first link 21 of the handle can be made of metal, for example, starting from a suitably bent metal tube to define an inverted U-shape. Alternatively, the first link 21 can be made of plastic or composite material.
[0197] The second link 22 of the handle extends laterally and vertically from the joint 40 to define the gripping section 22a of the operating handle 20.
[0198] The actuating handle 20, comprising the first and second elements 21, 22, can be shaped like a gamma (γ) or an X. Generally, the actuating handle 20 has a central constriction with respect to the coupling sections on the mobile device 1 and with respect to the gripping section 22a, with the joint 40 being located at this central constriction. In particular, the joint 40 is positioned centrally between the first and second coupling sections 21b of the actuating handle 20 along the transverse axis W, especially as seen from a rear view of the mobile device 1. In particular, as seen from a front view with respect to a plane ZW passing through the vertical axis Z and the transverse axis W, the joint 40 is positioned centrally between the means of motion 3 and aligned along a central axis of the mobile device 1.
[0199] Furthermore, the joint 40 can be positioned in an intermediate zone between the coupling sections of the first link 21 and the gripping section 22a of the second link 22 with respect to the distances: In particular, the joint 40 can be essentially equidistant between the coupling sections 21 and the gripping section 22a of the second link 22, with a maximum difference between the two distances of between 20% and 30%. In other words, after a total length L of the handle has been defined, the joint 40 is essentially arranged at half of this length L, with a maximum difference between the length of the first link 21 and the length of the second link 22 of between 20% and 30%.
[0200] The joint 40 includes a pivot point 41 that defines an axis of rotation B. The handle is designed to rotate about the axis of rotation B along a plane of rotation that is perpendicular to the axis of rotation B and transverse to the support surface SP of the mobile device 1. This rotation causes the actuating handle 20 to move along the steering axis D to the left side 12 and / or to the right side 13 of the mobile device 1. In other words, a component of the handle's rotational movement is aligned along the steering axis D. The plane of rotation is oriented at an angle between 30° and 70° with respect to the support surface SP, as shown in the perspective view in the accompanying figures. Fig. 1 to 4 inclined.
[0201] This pivot point 41 comprises the first coupling element 42, which is fixedly attached to the first link 21 of the actuating handle 20 and includes a through-hole; the second coupling element 43, which is fixedly attached to the second link 22 of the actuating handle 20 and includes a through-hole; and a pin 61 that passes through the through-hole of the first and second coupling elements 43 and extends along the axis of rotation B of the joint 40. This assembly defines a first link 21 of the actuating handle 20 that is fixed and attached to the mobile device 1, while the second link 22 of the actuating handle 20 has at least one rotational degree of freedom about the pivot point 41, defining the axis of rotation B, and allowing lateral movement of the second link 22 along the steering axis D.
[0202] In particular, the axis of rotation B of the joint 40 runs transversely to the support surface SP and is substantially parallel to, or lies on, a plane XZ that passes through the longitudinal axis X and the vertical axis Z. Furthermore, the axis of rotation B intersects a central axis of the mobile device 1, which is aligned with the longitudinal axis X. In addition, the axis of rotation B is inclined at an angle between 30° and 70° with respect to the longitudinal axis X along the plane XZ. This embodiment is described in Fig. 21 shown.
[0203] The Fig. Figures 12 to 19 show a further embodiment in which the joint 40 is also designed to accommodate a height H of the gripping section 22a of the actuating handle 20 in relation to the support surface SP according to the schematic representation in Fig. 15 to be amended: This height is defined in particular by the distance between the gripping section 22a of the handle and the support surface SP. According to this embodiment, the first element 21 of the handle is fixed and attached to the rear of the mobile device 1, while the second element 22 is movable in height.
[0204] In this respect, the joint 40 includes an adjusting insert 44, having in section an essentially wedge-shaped form as illustrated in the Fig. 16 and Fig. 17B. The adjusting insert 44 is inserted between the first coupling element 42 and the second coupling element 43 of the joint 40 and is rotatably movable about the axis of rotation B with respect to the first and / or second coupling element 43 of the joint 40. A rotation of the adjusting insert 44 of the joint 40 with respect to the first and / or the second coupling element 43 causes a simultaneous change in height of the gripping section 22a of the actuating handle 20 with respect to the support surface SP according to Fig. 15.
[0205] The adjusting insert 44 extends radially essentially around the axis of rotation B of the joint 40 and in the thickness between a first stop surface, designed to contact the first coupling element 42 of the actuating handle 20, and a second stop surface, designed to contact the second coupling element 43 of the actuating handle 20. The first and second stop surfaces are inclined to each other at an angle α between 4° and 20°, in particular between 6° and 15°, most particularly between 8° and 12°, preferably 10°. In particular, the first and second stop surfaces of the adjusting insert 44 are perpendicular to the vertical axis Z, wherein the first and second stop surfaces of the adjusting insert 44 are both arranged perpendicular to a plane XZ that passes through the longitudinal axis X and the vertical axis Z.
[0206] The first and second stop surfaces of the adjusting insert 44 thus cause a relative inclination between the first coupling element 42 and the second coupling element 43 and further cause the inclination of the rotation axis B of the joint 40 with respect to the support surface SP: As already mentioned, this inclination is projected onto the plane XZ.
[0207] The adjusting insert 44 is rotatable about the axis of rotation B: A rotation of the adjusting insert 44 with respect to the first and / or the second coupling element 43 of the joint 40 causes a simultaneous change in the inclination of the axis of rotation B of the joint 40 with respect to the support surface and in particular with respect to the first or second stop element: This change in inclination consequently causes the height change of the gripping section 22a of the operating handle 20 as shown in the illustration in Fig. 15. It is noted that the second link 22, during its height change, defines a rotational movement about a virtual axis C: This C-axis is defined as “virtual” because the joint 40 does not have a physical pivot point aligned along the C-axis; however, this rotation is effected by the special wedge-shaped form of the adjusting insert, which rotates about the rotation axis B, which is arranged perpendicular to the virtual axis C. The virtual axis C is shown schematically in Fig. Figure 14B illustrates this. In particular, the adjusting insert 44 defines a disc-shaped adjusting plate 44a, which has a wedge-shaped cross-section along the plane XZ. Furthermore, the first coupling element 42 also defines a first disc-shaped plate 42a and has a first stop surface suitable for contacting the first stop surface of the adjusting plate 44a. Similarly, the second coupling element 43 defines a second disc-shaped plate 43a and has a second stop surface suitable for contacting the second stop surface of the adjusting plate 44a. Since the first and second stop surfaces of the adjusting plate 44a are inclined relative to each other by the angle α, the first stop surface of the first plate 42a and the second stop surface of the second plate 43a are also inclined relative to each other by the same angle α.Accordingly, a rotation of the adjusting insert 44 about the rotation axis B of the joint 40 causes a simultaneous rotation of the second link 22 of the actuating handle 20 about the virtual axis C, which is schematically represented in . Fig. 14A, Fig. 14B, Fig. 17A and Fig. Figure 17B shows that the axis of rotation B of the joint 40 runs transversely and, in particular, perpendicularly to the virtual axis C of the second link 22 of the handle. In fact, the rotation of the adjusting insert about the axis of rotation B causes a simultaneous change in height of the gripping section 22a of the second link 22 of the actuating handle 20. The second link 22 of the actuating handle 20 can be positioned at least as follows: - in a lowered position in which the gripping section 22a of the actuating handle 20 has a first distance H to the support surface SP of the mobile device 1, wherein the adjusting insert 44 is positioned in a first angular position, and in - a raised position in which the gripping section 22a of the actuating handle 20 has a second distance H'' to the support surface SP of the mobile device 1: The second distance is greater than the first distance, and the adjusting insert 44 is positioned in a second angular position which is rotated 180° along the axis of rotation B of the joint 40 to the first angular position.
[0208] The inclination of the second element 22 of the actuating handle 20 can vary between the lowered and raised positions by an angle between 4° and 20°, in particular between 6° and 15°, most especially between 8° and 12°, preferably equal to 10°: The corresponding change in the height of the handle thus depends on the length extension of the second element 22 of the handle. It should be noted that this inclination is measured with respect to the support surface SP on a plane XZ which passes through the longitudinal axis X and the vertical axis Z of the mobile device 1.
[0209] The joint 40 may also include a locking system that is located in the Fig. 12 to 21 is shown and designed to connect the adjusting plate 44a, the first plate 42a and the second plate 43a of the actuating handle 20 to define a locking state and an adjustment state of the joint 40.
[0210] In particular, the adjusting plate 44a is rotatably movable about the axis of rotation B in the adjustment state of the joint 40 in order to vary the height of the gripping section 22a of the actuating handle 20: In addition, the second link 22 of the actuating handle is rotatably movable about the same axis of rotation B in the adjustment position in order to allow the displacement of the gripping section 22a along the steering axis D.
[0211] In the locked position of the joint 40, the relative rotation between the adjusting plate 44a and at least either the first and / or the second plate 43a of the operating handle 20 is prevented, so that both the rotation of the second link 22 of the handle about the axis of rotation B and the height adjustment of the handle are locked. In the locked position, the locking system brings the adjusting plate 44a into a stop between the first and the second plate 43a of the joint 40 in order to prevent a relative rotation between the first plate 42a, the adjusting plate 44a and the second plate 43a.
[0212] The locking system comprises a pin 61 that extends transversely through the respective central bores of the joint 40, that is, through the first plate 42a of the joint 40, the adjusting plate 44a, and the second plate 43a of the joint 40. The locking system also comprises a first locking element 62, for example, a screw-on rotary knob for adjusting the usable length of the through pin 61, which engages in a first end of the through pin 61 and forms a stop against at least either the first and / or second plate 43a of the joint 40, as shown in the section view. Fig. 17B defined. The locking system also includes a second locking element 63, for example a locking lever which can be operated by hand, which engages with a second end of the through pin 61 and is movable between a closed position and an open position.
[0213] In the closed position, the first plate 42a, the adjusting plate 44a, and the second plate 43a are forcibly engaged by pressure to define an axial fixation along the rotation axis B of the joint 40: The first locking element 62 is forcibly engaged against the first or second plate 43a of the joint 40, while a section of the second locking element 63 is forcibly engaged against the other, i.e., the first or second plate 43a. Accordingly, the adjusting plate 44a is pressed between the first and second plates 43a along the rotation axis B of the joint 40: The closed position results in the locking state of the joint 40.
[0214] In the open position, the through pin 61 allows an axial degree of freedom essentially along the axis of rotation B for at least either the first plate 42a and / or the second plate 43a and / or the adjusting plate 44a, thus enabling a rotational degree of freedom of the adjusting plate 44a.
[0215] In other words, when the locking system is in the closed position, the central bolt 61 clamps the adjusting insert 44, the first coupling element 42, and the second coupling element 43 of the joint 40 against each other to prevent their relative rotation. To further prevent relative rotation between the adjusting insert 44 and the first and second coupling elements 43, the adjusting insert 44 also includes a toothed section 47 along at least either the first and / or second stop surface. This toothed section 47 comprises a sequence of protrusions and depressions extending in height and depth in a direction substantially parallel to the axis of rotation B of the joint 40. Similarly, the first and / or second coupling element 43 each include a toothed section 48 designed to engage with the toothed section 47 of the adjusting insert 44, at least when the joint 40 is locked.The respective toothing of the adjusting insert 44 and the first and / or second coupling element 43 face each other and are designed to interlock during the locking state, thus preventing rotation. In other words, the second link 22 of the handle is locked from rotating in this embodiment when the locking system is in the closed position corresponding to the locking state of the joint 40. When the locking system is in the open position, the operating handle 20 in this embodiment can therefore rotate freely about the axis of rotation B of the joint 40 and be moved to the left and to the right. Furthermore, the adjusting insert 44 can also rotate freely about the axis of rotation B with respect to the first coupling element 42, in order to also allow a change in height of the gripping section (22a) of the handle. Fig. Figures 12 to 19 show this embodiment, in which the handle can be rotated around the axis of rotation B to facilitate the maintenance processes within the work area, and can be moved in height by means of the adjusting insert 44.
[0216] In a Fig. In the embodiment shown in Figure 21, the joint comprises the first coupling element 42 and the second coupling element 43, which face each other, each comprising a respective toothing designed to cooperate with each other so that rotation of the first coupling element 42 relative to the second coupling element 43 is prevented: This toothing thus prevents rotation of the second member 22 of the actuating handle relative to the first member 21 of the actuating handle. The embodiment from Fig. 21 does not include the adjusting insert 44: The first and second coupling elements 42, 43 of the joint 40 are thus in contact with each other to enable or prevent mutual rotation. In this embodiment, the joint 40 can include an elastic auxiliary element 46, for example a coiled compression spring, which is inserted between the first plate 42a and the second plate 43a of the actuating handle 20 and acts: The elastic auxiliary element 46 is thus designed to exert a repulsive force between the first plate 42a and the second plate 43a of the actuating handle 20, so that the teeth of the first plate 42a and the second plate 43a are disengaged and, accordingly, rotation about the axis of rotation B of the joint between the second member 22 and the first member 21 is enabled.
[0217] The joint 40 can also include an elastic adjusting element 45, for example a coiled compression spring, which is inserted between the adjusting plate 44a and at least either the first and / or the second plate 43a of the actuating handle 20 and acts as follows: The elastic adjusting element 45 is designed to exert a repulsive force between the adjusting plate 44a and at least the first and / or second plate 43a of the actuating handle 20. In the section view shown in Fig. In the embodiment shown in Figure 17B, the elastic adjusting element 45 is inserted between the adjusting plate 44a and the second plate 43a of the second link 22 of the actuating handle 20 and acts between them. When the joint 40 is in the adjustment state, the elastic element moves the adjusting plate 44a axially away from the first and / or second plate 43a of the actuating handle 20 along the axis of rotation B of the joint 40. This distance allows one degree of rotational freedom of the adjusting plate 44a with respect to the first and / or second plate 43a to effect the height adjustment of the actuating handle 20. The elastic adjusting element 45 is preferably concentric with the axis of rotation B of the joint 40.
[0218] When the joint 40 is in the release state, the elastic adjusting element 45, combined with the toothing of the adjusting insert 44, allows the operator to rotate the adjusting insert 44 in individual steps defined by the toothing, thereby improving the operability of the adjusting insert. In other words, the elastic adjusting element 45, combined with the toothing of the adjusting insert 44, exerts a resistive moment on the adjusting insert 44 during its rotation about the axis of rotation B.
[0219] The elastic adjusting element 45 and the elastic auxiliary element 46 can be concentric to each other, with the elastic auxiliary element 46 being radially inside the elastic adjusting element 45.
[0220] The actuating handle 20 also comprises a fastening section 23 between the joint 40 and at least either the first and / or second link 21, 22 of the actuating handle 20: This fastening section creates a fixed coupling between the joint 40 and the first or second link 22 of the actuating handle 20. The accompanying figures show an embodiment in which the fastening section 23 firmly connects the first link 21 of the handle to the first coupling element 42 of the joint 40.
[0221] It should be noted in particular that the first link 21 of the actuating handle 20 and the first coupling element 42 form a single body according to the embodiment of the attached figures: In particular, the fastening section 23 does not allow rotation between the first link 21 of the handle and the first coupling element 42.
[0222] Furthermore, it should be noted that during operation of the mobile device 1, the operating handle 20 is predominantly loaded by the operator in one direction of travel and along a direction that is essentially perpendicular to the ground: To lift the front wheels of the mobile device 1, the operator must load the operating handle 20 along a direction that is essentially vertical in order to exert leverage on the rear wheels. This behavior is very frequently performed by the operator during maintenance operations, thus defining a cyclic load on the handle and a moment acting on the joint 40 about the virtual axis C: The fact that the joint 40 of this operating handle 20 does not have a pivot point 41 aligned along the virtual axis C therefore provides a significant advantage with regard to the reliability of the joint 40.Furthermore, even if the locking system were left loose or in the open position, the handle would not fall to the ground, even if subjected to a vertical load by the operator. The coupling plates 42a, 43a, which extend towards each other along a plane perpendicular to the direction of the applied load, prevent this applied load from subjecting the joint 40 to a cyclic torsional load and, in fact, effect a traction load on the through pin 61 of the locking system.
[0223] In other words, the design of joint 40 described above allows for height adjustment of the handle as well as its rotation to the left and right, thereby simultaneously improving the fatigue resistance of joint 40.
[0224] Furthermore, the second link 22 is rotatable about the axis of rotation B relative to the first link 21 between an operating position and a folded-in position, particularly when it is in the release position. In the operating position, the second link 22 is as shown in the illustration. Fig. 2 to 5 are arranged either in the right-hand side position, the left-hand side position, or the center position: In other words, when the second link is arranged in the operating position, it is designed to be gripped by an operator to guide the mobile device within the working area. When the second link 22 is arranged in the left-hand or right-hand side position, it is rotated angularly with respect to its center position by an angle between 20° and 60°, in particular between 25° and 45°.
[0225] In the folded position, the second link, on the other hand, is rotated with respect to its central position and about the axis of rotation B by an angle between 170° and 190°, in particular equal to 180°, according to the illustrations in the Fig. 18 and Fig. 19. Rotated: In other words, the second link 22 is rotated with respect to the position in which the handle is designed to allow the guidance of the mobile device until it is positioned above the support frame of the mobile device, i.e., above the mobile device itself and in a position close to the mobile device. In the folded position, the mobile device is positioned, in particular along the vertical axis Z, between the second link 22 of the operating handle 20 and the support surface SP.
[0226] The displacement between the operating position and the folded position is permissible if the locking system is in its open position and / or if the joint is in the adjustment state and / or if the shift clutch system is in the release state.
[0227] In summary, the operating handle 20 is designed to - to position itself in the central, left-side and / or right-side position when rotating around the axis of rotation B, in order to allow an operator to easily guide the mobile device during an operating state; - to adjust the height of its own gripping section 22a by rotating the adjustment insert 44 around the axis of rotation B; - to arrange itself, when the second link 22 of the handle 20 is rotated about the axis of rotation B, essentially at an angle of 180° with respect to its central position in the folded position, in order to reduce the space occupied by the handle. MOBILE OPERATING BODY AND DRIVE SYSTEM
[0228] According to one embodiment, the operating body 5 is particularly movable translationally along a translational axis Y horizontally to the ground. The translational axis Y also runs essentially parallel to the support surface SP and essentially perpendicular to the longitudinal axis X. Furthermore, the translational axis Y can be arranged essentially perpendicular to the vertical axis Z of the mobile device 1. In other words, this design allows the operating body 5 to be moved laterally during an operating state of the device, as shown in the illustrations. Fig. 8A, Fig. 8B and Fig. 9, defining a movement of the operating body 5 to the left and to the right. This lateral movement enables maintenance operations to be carried out in hard-to-reach areas, for example near a slope as shown in Fig. 8A or under a hedge as shown in Fig. 8B or as shown in the illustration in Fig. 9 obstacles to avoid.
[0229] It is further noted that the rotation axis A of the working tool 4 is essentially parallel to the vertical axis of the mobile device 1 and perpendicular to the translation axis Y of the operating body 5.
[0230] In particular, the operating body 5 is movable along the translational axis Y between a right-side position and a left-side position, the left-side and right-side positions defining the maximum end limits within which the operating body 5 is movable along the translational axis. In the right-side position, a first end section 5a of the operating body 5 has a maximum distance to the central axis of the mobile device 1, while a second end section 5b of the operating body 5, opposite the first end section 5a, has a minimum distance to the central axis. The first and second end sections 5b are positioned along the translational axis Y: Optionally, the first end section 5a is symmetrical with respect to the second end section 5b with respect to the central axis of the mobile device 1.If, on the other hand, the operating body 5 is in the left lateral position, the first end section 5a of the operating body 5 has a minimum distance to the central axis, while the second end section 5b of the operating body 5 has a maximum distance to the central axis. It should be noted in particular that a straight line passing through the first and second end sections 5b of the operating body 5 can be aligned with or parallel to the translation axis Y.
[0231] The operating body 5 can also be positioned in a central position located between the left and right side positions: In the central position, the first and second end sections 5b of the operating body 5 can be equidistant from the central axis of the mobile device 1. In other words, the central position defines a midpoint of the operating body 5a between the left and right side positions. A maximum movement value of the operating body 5 along the translational axis Y with respect to the central position is between 5 cm and 40 cm, specifically between 10 cm and 30 cm.
[0232] To enable the movement of the operating body 5 along the translational axis Y, the device can comprise one or more rails 6 that are fixedly attached to the support frame 2 and support the operating body 5. These rails 6 can be bolted or welded to the support frame 2 and are fixed with respect to the frame. In particular, the rails 6 extend lengthwise parallel to the transverse axis W of the mobile device 1. In particular, the rails 6 have an elongated cylindrical shape.
[0233] The mobile device 1 preferably comprises a first and a second rail 6a, 6b, which run parallel to each other and extend along a respective longitudinal direction parallel to the translation axis Y: The first and the second rail 6a, 6b extend in length between a respective first end, which faces the right side 13 of the mobile device 1, and a second end, which faces the left side 12 of the mobile device 1.
[0234] The first rail 6a is preferably arranged substantially on the front section 10 of the mobile device 1, while the second rail 6b is preferably arranged on the rear section 11 of the mobile device 1.
[0235] It should be noted that the guides support the operating body 5 vertically and prevent its movement along the longitudinal axis X, while at the same time allowing the movement of the operating body along the translational axis Y.
[0236] The mobile device 1 further comprises one or more guides that are fixedly attached to the operating body 5, forming a single body and cooperating with the respective rails 6. In particular, the guides cooperate with the rails 6 to support the operating body 5 vertically and simultaneously allow its movement along the translational axis Y: The guides are thus movable along the translational axis Y together with the operating body 5. It should be noted that the guides support the operating body 5 vertically and prevent its movement along the longitudinal axis X.
[0237] In particular, the mobile device 1 comprises a first and a second guide 8a, 8b, each of which includes a corresponding eyelet with a through-opening: The first rail 6a is inserted into the through-opening of the eyelet of the first guide, while the second rail 6b is inserted into the through-opening of the eyelet of the second guide. The first and the second guide 8a, 8b thus move on the respective first and second rails 6a, 6b and enable the movement of the operating body 5 along the translational axis Y.
[0238] In particular, the first guide is located on the front section 10 of the mobile device 1, while the second guide is located on the rear section 11 of the mobile device 1.
[0239] The opening of each eyelet defines a central axis parallel to the translation axis Y: In particular, this central axis of each eyelet essentially coincides with the length of the rail traversing it.
[0240] The eyelet can be made of metal or plastic. In particular, a bushing made of a material with a low coefficient of friction, such as plastic or polytetrafluoroethylene (PTFE), can be inserted between the eyelet and the rail to facilitate the relative movement. Alternatively, a ball bearing can be inserted between the eyelet and the rail, further improving the relative movement.
[0241] The operating body 5 can be moved manually or automatically along the translation axis Y.
[0242] In the embodiment in which the operating body 5 is arranged according to the illustrations in the Fig. The mobile device 1, which is movable by hand along the translation axis Y from 1 to 5, comprises a drive system 30 which is connected to the actuating handle 20 and is designed to control the movement of the operating body 5 along the translation axis Y.
[0243] In one embodiment, the drive system 30 comprises the joint 40 in one of the previously described embodiments, enabling the actuating handle 20 to be moved along the steering axis D. In particular, the actuating handle is moved along the steering axis D by rotating the handle about the rotation axis B of the joint 40.
[0244] The drive system 30, which is connected to the joint 40, is thus designed to cause the operating body 5 to move along the translation axis Y when the actuating handle 20 is moved along the steering axis D.
[0245] In accordance with a preferred, in Fig. 8A and Fig. In the embodiment shown in Figure 8B, moving the actuating handle 20 along the steering axis in a first direction causes the operating body 5 to move simultaneously along the translation axis Y in a second direction opposite to the first direction, and vice versa. In other words, moving the actuating handle 20 to the left causes the operating body 5 to move simultaneously to the right; similarly, moving the actuating handle 20 to the right causes the operating body 5 to move simultaneously to the left.
[0246] The drive system 30 is a mechanical system that physically connects the operating handle 20 to the operating body 5.
[0247] In the Fig. In the embodiment shown in Figures 1 to 4 and 21 to 22, the joint 40 is designed to allow the actuating handle 20 to rotate about a rotation axis B in order to effect the simultaneous displacement of the operating body along the translation axis Y.
[0248] The actuating handle 20 lies on an actuation plane transverse to a plane of the operating body 5 and is arranged transversely to the support surface. When the actuating handle 20 is rotated, it rotates along the actuation plane so that the axis of rotation B of the handle is arranged perpendicular to the actuation plane on which the actuating handle 20 lies.
[0249] The axis of rotation B of the drive system 30 can be located at a central section of the actuating handle 20, positioned between the first and second ends of the handle. In other words, the central section is located between the first and, optionally, substantially equidistant from the first and second ends of the actuating handle 20. Since the actuating handle 20 is inclined, the drive system 30 is located at a distance from the support surface that is greater than the corresponding distance between the first end and the support surface. In particular, the drive system 30 is positioned at a distance from the support surface that is between 20 cm and 100 cm, and more specifically between 25 cm and 60 cm.
[0250] In an alternative embodiment with respect to the joint 40, the drive system 30 comprises an operating lever 90, which is supported by the handle and can be actuated by an operator, for example, translationally or rotationally, and which is operationally connected to the operating body 5 as shown in the illustration. Fig. 5 is connected. The operating lever 90 is thus designed to cause a simultaneous movement of the operating body 5 along the translational axis Y when moved.
[0251] The drive system 30 preferably comprises one or more actuating cables 31 that connect the drive system 30, in particular the actuating handle 20 or the operating lever 90, to the operating body 5. The connecting cables are designed to transmit movement of the actuating handle 20 along the steering axis D or movement of the operating lever 90 to the operating body 5 in order to effect simultaneous movement along the translational axis Y. It should be noted that movement of the actuating handle 20 along the steering axis D causes a movement of the operating body 5 along the translational axis Y that is proportional in width, wherein, in particular, an increase in the displacement of the actuating handle 20 along the steering axis D causes a proportional increase in the displacement of the operating body 5 along the translational axis Y.In other words, the more an operator moves the operating handle 20 to the left or to the right, the more the operating body 5 is moved accordingly.
[0252] In particular, the drive system 30 can have a first and a second actuating cable 31a, 31b as shown in Fig. 2, wherein each first and second cable is positioned in connection between the actuating handle 20 and the operating body 5 or between the operating lever 90 and the operating body 5: The first cable 31a can be designed to pull the operating body 5 to the right along the translational axis Y, while the second cable 31b can be designed to pull the operating body 5 to the left along the translational axis Y. The steel cables are flexible and can be made of steel or composed of steel strands. In particular, the first actuating cable 31a extends in length between a first end connected to a first section of the operating body and a second end connected to the joint, in particular to a traction element 32 of the joint 40.Accordingly, the second actuating cable 31b extends in length between a first end, which is connected to a second section of the operating body, and a second end, which is connected to the joint, in particular to a traction element 32 of the joint 40. The first and second sections of the operating body 5, to which the respective cables 31a, 31b are fixedly attached, are opposite to each other with respect to the axis of rotation A of the working tool: In particular, the first section is located on the right side of the mobile device, while the second section is located on the left side of the mobile device. Alternatively, the drive system 30 can have a single actuating cable as shown in Figure 5. Fig. 3 comprising a single actuating cable extending between a first end and a second end, both of which are connected to the operating body 5, and wherein the single actuating cable passes through the joint 40: The single cable may be wound around the joint 40 or connected to a traction element 32 of the joint. For example, the first end of the single actuating cable is connected to a right section of the operating body, while the second end of the single actuating cable is connected to a left section of the operating body. In another embodiment, the drive system 30 may include a single actuating cable as shown in Fig. 4 and Fig. 5 comprising a single actuating cable extending between a first end connected to a section of the operating body and a second end connected to the operating lever 90. The single actuating cable can pass through the joint 40 to reach the operating lever near or on the gripping section 22a of the actuating handle. In this embodiment with a single actuating cable, the drive system 30 can include a return element, for example, a tension or compression spring, which is inserted in connection between the operating body 5 and the support frame 2 and is designed to move the operating body 5 along a return direction opposite to an actuation direction effected by the single actuating cable.If, for example, the individual actuating cable is designed to pull the operating body to the right, the return element is designed to pull the operating body to the left, so that the operating body is moved to the left by the return element, for example, into the center position, when the operator releases the operating lever 90. Conversely, if the individual actuating cable is designed to pull the operating body to the left, the return element is designed to pull the operating body to the right, so that the operating body is moved to the right by the return element, for example, into the center position, when the operator releases the operating lever 90.In a further embodiment, not shown in the accompanying figures, the drive system 30 may, for example, comprise a single actuating cable extending between a first end connected to a section of the operating body and a second end connected to the joint 40, whereby a rotation of the actuating handle about the axis of rotation B actuates the single actuating cable to pull the operating body to the left or right. In this embodiment with a single actuating cable, the drive system 30 may include a return element, for example, a tension or compression spring, which is inserted in connection between the operating body 5 and the support frame 2 and is designed to move the operating body 5 along a return direction opposite to an actuation direction effected by the single actuating cable.If, for example, the individual actuating cable is designed to pull the operating body to the right, the return element is designed to pull the operating body to the left, so that the operating body is moved to the left by the return element, for example, into the respective center position, when the operator releases the actuating handle or returns it to a center position. Conversely, if the individual actuating cable is designed to pull the operating body to the left, the return element is designed to pull the operating body to the right, so that the operating body is moved to the right by the return element, for example, into the center position, when the operator releases the actuating handle or returns it to a center position.
[0253] In another embodiment, which is described in Fig. As shown in Figure 5, the drive system 30 can comprise one or more actuating cables 31, for example, one or more actuating cables in which at least one end of the actuating cable is attached to a tensile section 2a of the support frame 2 and the actuating cable passes through the operating body 5. Such a drive system can also comprise at least one sheath 35 for each actuating cable 31: The sheath 35 can be flexible or rigid. The actuating cable 31 is inserted into the respective sheath 35 and extends between a first end 31', which is attached to the tensile section 2a of the support frame, and a second end 31'', which is connected to the operating lever 90 or the joint of the actuating handle 20: Accordingly, the sheath 35 extends between a respective first end 35 and a second end 35''.The operating body 5 comprises a respective pull section 15, comprising a through-hole for the passage of the actuating cable 31, wherein the pull section 15 of the operating body 5 is inserted between the first end 31' of the actuating cable 31 and the first end 35' of the sheath 35: In particular, the first end 35' of the sheath 35 is in the stop of the pull section 15 of the operating body 5. In this way, the pull of the winding cable 31 causes the operating body to move simultaneously to the left or to the right side of the mobile device, in particular such that the first end 31 of the actuating cable 31' approaches the pull section 15 of the operating body 5.
[0254] In the embodiment from Fig. 5 the drive system 30 comprises a first actuating cable 31a, a second actuating cable 31b, a first sheath 35a mounted on the first actuating cable 31a, a second sheath 35b mounted on the second actuating cable 31b, a first pull section 2a' and a second pull section 2a'' of the support frame 2 and a first pull section 15a and a second pull section 15b of the operating body, wherein - the first end 31a' of the first actuating cable 31a is attached to the first pull section 2a' of the support frame 2 and the first sheath 35a abuts the first pull section 15a of the operating body 5, wherein the first pull section 15a of the operating body 5 is inserted between the first sheath 35 and the first pull section 2a' of the support frame 2; - the first end 31b' of the second actuating cable 31b is attached to the second pull section 2a'' of the support frame 2 and the second sheath 35b abuts the second pull section 15b of the operating body 5, wherein the second pull section 15b of the operating body 5 is inserted between the second sheath 35 and the second pull section 2a'' of the support frame 2.
[0255] The Fig. 6 and Fig. Figure 7 shows an embodiment of the drive system 30 of the actuating handle 20, which enables the operating body 5 to be moved along the translational axis Y when the actuating handle 20 is moved laterally along the steering axis D. In this embodiment, the drive system 30 comprises a traction element 32, which is attached to the actuating handle 20 at the joint 40 and is rotatably movable essentially about the rotational axis B of the joint 40, whereby a rotation of the actuating handle 20 causes a corresponding rotation of the traction element 32. The traction element 32 is thus designed to bring the cables 31 into traction during a rotation of the actuating handle 20 in order to move the operating body 5 along the translational axis Y to the left side 12 and to the right side 13 of the mobile device 1.The traction element 32 has a circular or semicircular lateral surface that is radially spaced from the axis of rotation B of the joint 40: The actuating cables 31 are as shown in the illustrations in the . Fig. 2 and Fig. 3 at least partially wrapped around the lateral surface of the traction element 32. In particular, the first cable may be wrapped around a right section of the lateral surface, while the second cable may be wrapped around a left section of the lateral surface: It should be noted that the left section of the lateral surface faces the left side 12 of the mobile device 1, while the right section of the lateral surface faces the right side 13 of the mobile device 1.
[0256] For example, in the Fig. 2 and Fig. In the schematically illustrated embodiment 3, the drive system 30 comprises a shift clutch system 33, which is active on the joint 40 and can be configured in a locking position. In this position, the shift clutch system 33 is configured to lock the joint 40, thus preventing the movement of the actuating handle 20 along the steering axis D. In particular, rotation of the actuating handle 20 about the axis of rotation B of the joint 40 is prevented when the shift clutch system 33 is in the locking position. The shift clutch system 33 can also be configured in a release position. In this position, the shift clutch system 33 is configured to release the joint 40 and allow movement of the actuating handle 20 at least along the steering axis D. In particular, rotation of the actuating handle 20 about the axis of rotation B of the joint 40 is allowed when the shift clutch system 33 is in the release position.
[0257] The shift clutch system 33 comprises an activation element 34, for example, a handle or a lever, designed to be operated by an operator and to selectively position the shift clutch system 33 in either the locked or the released position. The activation element 34 can be connected to the joint 40 by means of a connecting cable inserted between the lever and the activation element 34. The shift clutch system 33 at the joint 40 can include a movable locking element controlled by the connecting cable to allow or prevent rotation of the activation handle about the axis of rotation B. In this embodiment, the movable locking element is designed to engage with a toothing located on at least either the first and / or the second link of the actuating handle, for example, on the first coupling element 42 of the first link 21.
[0258] In accordance with one of the Fig. 24 and Fig. In the embodiments shown in Figure 25, the drive system 30 can comprise a planetary gear 36, which is operationally inserted between the first element 21 and the second element 22 of the actuating handle 20 and is designed to increase or decrease, in particular to increase, the lateral movement of the operating body 5 along the translational axis Y during the same rotation of the second element 22 of the actuating handle about the rotational axis B. In other words, the planetary gear 36 defines a transmission ratio between the movement of the second element 22 of the actuating handle 20 and the movement of the operating body 5: Depending on the design of the planetary gear, this transmission ratio can be configured as a multiplication or reduction of the displacement of the operating body 5. The embodiment shown in Figure 25 Fig. 24 and Fig. 25 is suitable for multiplying the displacement brought about by the second element 22 of the operating body 5.
[0259] In general, the 36-piece planetary gear set includes the following: - a central pinion 37 having an axis of rotation which is parallel to or substantially coincides with the axis of rotation B of the joint 40; - an outer round ring 39, which in particular has an internal toothing and is rotatably movable about the axis of rotation of the central pinion 37; - at least one carrier 38, which carries one or more planet gears 38a, 38b, 38c and is rotatably movable about the axis of rotation of the central pinion 37, wherein the planet gears 38a, 38b, 38c are inserted radially between the central pinion 37 and the outer round ring 39 and engage in the central pinion 37 and the outer round ring 39.
[0260] In the embodiment of the Fig. 24 and Fig. The planetary gear 36 comprises the following: 25 - the outer round ring 39, which is attached to the first link 21 of the operating handle 20: In particular, the outer round ring 39 is fixed in relation to the second link 22; - the carrier 38, which is attached to and firmly connected with the second link 22 of the operating handle 20, such that a rotation of the second link 22 about the axis of rotation B causes a simultaneous rotation of the carrier 38 about the axis of rotation of the carrier 38: It should be noted in particular that each planetary gear 38a, 38b, 38c is rotatably movable about its own axis of rotation D and about the axis of rotation of the carrier; - the central pinion 37, which is rigidly connected to the traction element 32: The traction element is optionally a disc that is operationally connected to the actuating cable(s) 31 to transmit the movement to the operating body 5. For example, an actuating cable can be wrapped around or attached to the disc to transmit the movement to the operating body 5.
[0261] Alternatively, the outer round ring 39 can be firmly connected to the second link 22, the support 38 can be attached to the first link 21, and the central pinion 37 can be firmly connected to the traction element 32.
[0262] The drive system 30 according to the embodiment comprising the planetary gear can also include the previously described shift clutch system 33, which is rigidly connected to the second member 22 and acts externally on the outer circular ring 39 of the planetary gear. In this respect, the outer circular ring 39 comprises a toothing 39a that extends radially outwards and is designed to cooperate with the shift clutch system 33, at least when the shift clutch system 33 is in the locked position.
[0263] The joint 40 of the actuating handle 20 can also be designed in accordance with a further embodiment, which is described in the Fig. Figures 12 to 19 show: In this case, the joint 40 can operate like the drive system 30 described above to move the operating body 5, or it can only allow the lateral movement of the actuating handle 20, without necessarily actuating the operating body 5 along the translational direction Y or along the vertical direction Z.
[0264] Alternatively, in an embodiment not shown, the drive system 30 can be designed to cause the operating body 5 to move along the vertical axis Z when the actuating handle 20 is moved along the steering axis, thus changing the distance between the working tool 4 and the support surface: In other words, this change in height causes a corresponding change in the distance between the working tool 4 and the ground during an operating state, so that, for example, the cutting height of the grass is changed.
[0265] In one embodiment, the device is arranged according to the illustration in Fig.In this configuration, the self-propelled mobile device 1 does not include the operating handle 20. In this configuration, the self-propelled mobile device 1 may include at least one obstacle detector 9 designed to detect one or more obstacles in the work area while the mobile device 1 is moving within the work area. Specifically, the obstacle detector 9 may include at least one proximity sensor, such as an ultrasonic or optical sensor, and / or a video camera and / or a time-of-flight sensor. If a video camera is provided, a control unit 50 may be designed to detect and optionally identify an obstacle 100, for example, by identifying the obstacle 100. The autonomous driving control system may include an extensive wiring system, a guidance system using a GPS sensor, or one or more video cameras.The control system for autonomous driving is not described in detail, as it already represents the state of the art.
[0266] The self-propelled mobile device 1 can also include at least one actuator which is operationally connected to the operating body 5 and is designed to move the operating body 5 along the translation axis Y, in particular to the left side 12 or to the right side 13 of the mobile device 1: In this design, this actuator thus defines the drive system 30 of the operating body 5.
[0267] A control unit 50 of the mobile device 1 is operationally connected to the traction motor of the mobile device 1, the obstacle detector 9 and the actuator of the operating body 5: The control unit 50 can be designed to receive at least one signal from the obstacle detector 9 that is representative of the presence of an obstacle 100 along the path of the mobile device 1, and to control the actuator so that the operating body 5 is moved into the central position when the detector detects an obstacle 100.
[0268] The control unit 50 can also be designed to determine whether the obstacle 100 is located on the left side 12 or to the right of the mobile device 1, and to determine whether the operating body 5 is in the left-side position or in the right-side position. The control unit 50 is thus designed to - to control the actuator so that the operating body 5 is moved from the left side position to the center position or the right side position when it is determined that the obstacle 100 is located on the left side 12 of the mobile device 1, and it is determined that the operating body 5 is in the left side position; - to control the actuator so that the operating body 5 is moved from the right side position to the center position or the left side position when it is determined that the obstacle 100 is located on the right side 13 of the mobile device 1, and it is determined that the operating body 5 is in the right side position; - to maintain the operating body 5 in the right-hand side position when it is determined that the obstacle 100 is located on the left side 12 of the mobile device 1, and it is determined that the operating body 5 is in the right-hand side position; - to keep the operating body 5 in the left side position when it is determined that the obstacle 100 is located on the right side 13 of the mobile device 1, and it is determined that the operating body 5 is in the left side position.
[0269] Furthermore, if it is specified that the obstacle 100 is located on the right side 13 and the left side 12 of the mobile device 1, the control unit 50 is designed to control the actuator so that it moves the operating body 5 from the right or left side position to the central position and optionally controls the stopping of the means of movement 3. ADVANTAGES OF THE INVENTION
[0270] This invention facilitates easier work in areas adjacent to obstacles such as trees, hedges, or flowerbeds. In particular, this invention allows for greater flexibility in the use of the mobile device 1, since the translation of the operating unit 5, especially the mowing deck, enables closer access to otherwise inaccessible areas. This translation also allows the operator to move away from the obstacle 100 while simultaneously keeping the operating unit 5 mowing against the obstacle 100.
[0271] It is further noted that with boundary hedges, it is often necessary to work with the mobile device 1 under part of the hedge, down to the trunk. The mobile device 1 of this invention enables work under the hedge while the operator is in a displaced position and moves the operating body laterally along the translation axis Y and / or moves the operating handle along the steering axis D and / or adjusts the height of the operating handle, thus accelerating and facilitating maintenance operations within the working area.
