Description

Technical Field

[0001] The invention relates to an industrial truck with a driver's station having a driver's seat and a floor. Background Art

[0002] When the industrial truck is configured as a so-called sit-down machine and is operated by the operator in a seated position, a driver's station is provided having a driver's seat and a floor, with the operator seated in the driver's seat resting their feet on the floor. For this purpose, the floor preferably has a foot support surface on its upper side. The foot support surface is preferably configured so that the operator seated in the driver's seat can rest their feet on it. A pedal arrangement may be arranged on the floor, comprising at least one pedal. The at least one pedal of the pedal arrangement can be operated by the operator seated in the driver's seat with one or both feet. The pedal arrangement may be configured as a single-pedal arrangement with a single accelerator pedal, which can be used to control the speed of the industrial truck, or as a double-pedal arrangement with two accelerator pedals, which can be used to control the speed and direction of travel of the industrial truck. The pedal arrangement may also include a brake pedal.

[0003] In industrial trucks of this type, which comprise a driver's seat and a floor panel, which is provided with a footrest and preferably with a pedal arrangement, it is known that the floor panel is arranged rigidly and non-adjustably in the driver's station, so that the operator can adjust the driver's seat to suit ergonomic requirements, for example by adjusting the height of the driver's seat and adjusting the driver's seat in its longitudinal direction.

[0004] Furthermore, in such industrial trucks comprising a driver's seat and a floor (which floor is provided with a footrest and preferably a pedal arrangement), it is also known that the floor is arranged in the driver's station so that the floor can be adjusted in the vertical direction. This allows the operator to adjust the height of the floor in addition to adjusting the driver's seat to suit ergonomic requirements by adjusting the height of the floor in the vertical direction. DE 4413630 C2 discloses an industrial truck with a driver's station comprising a driver's seat and a floor with a pedal arrangement, wherein the floor is arranged in the driver's station so that the floor can be adjusted in the vertical direction. A disadvantage of DE 4413630 C2 is that, since the floor with the pedal arrangement requires a vertical guide, the vertically adjustable floor requires a relatively large installation space in the industrial truck and is complex to manufacture. Summary of the Invention

[0005] The object of the present invention is to provide an industrial truck of the type mentioned initially which is improved with regard to the above-mentioned disadvantages.

[0006] According to the invention, this object is achieved in that the floor is arranged in the driver's station so that its inclination is adjustable about an inclination axis.

[0007] According to the present invention, a base plate with a footrest surface is adjustable in inclination about a tilt axis and is thus adjustable in the driver's station. The angle of attack of the base plate with the footrest surface can therefore be varied and oriented. Compared to base plates with vertical height adjustment, base plates with adjustable inclination about a tilt axis do not require vertical guides. Consequently, base plates with adjustable inclination about a tilt axis have a simpler design, require less installation space, and are less complex. The tilt axis is preferably formed by a simply designed hinge that is fastened to the base plate and the driver's station. Since the base plate can be adjusted in inclination about the tilt axis and thus can be oriented in angle of attack, the footrest surface constructed on the base plate can be ergonomically adapted to the requirements of operators of different heights, enabling an ergonomically suitable working position, while requiring less installation space and requiring less complex construction. In particular, if the driver's seat has limited height adjustment, a base plate with adjustable inclination and adjustable height can easily adapt to the ergonomic requirements of operators of different heights and enable an ergonomically suitable working position.

[0008] According to an advantageous embodiment of the present invention, a pedal arrangement comprising at least one pedal is arranged on the floor. Because the floor can be adjusted in inclination about an inclination axis and thus oriented in terms of angle of attack, the pedal arrangement and the accelerator pedal arrangement arranged on the floor can be ergonomically adapted to achieve an ergonomically suitable working position for operators of different heights, while requiring minimal installation space and requiring minimal structural effort. In particular, if the driver's seat has limited height adjustment, a floor with an adjustable and tiltable pedal arrangement can easily adapt to ergonomic requirements and achieve an ergonomically suitable working position for operators of different heights.

[0009] According to an advantageous embodiment of the invention, the floor panel has a front region facing away from the driver's seat and a rear region facing the driver's seat, and the tilt axis is arranged in the rear region of the floor panel facing the driver's seat. The tilt axis of the floor panel is preferably arranged perpendicular to the longitudinal direction of the driver's seat. This allows the inclination of the floor panel with the footrest and / or pedal arrangement to be adjusted in a simple manner and its angle of attack relative to the driver's seat to be varied.

[0010] According to an advantageous embodiment of the present invention, the pedal arrangement is arranged in a front region of the floor panel facing away from the driver's seat. This allows the floor panel, whose inclination can be adjusted about the inclination axis and thus whose angle of attack can be oriented, to adapt the pedal positions of the pedal arrangement and the accelerator pedal arrangement arranged on the floor panel to ergonomic requirements and achieve an ergonomic working position for operators of different heights while requiring minimal installation space and requiring minimal structural effort.

[0011] According to an advantageous embodiment of the invention, the base plate is arranged to be infinitely adjustable or to be adjusted in a snap-lock manner about the tilt axis. By means of infinitely adjustable or snap-locking adjustment, the operator can easily adapt and adjust the inclination of the base plate to ergonomic requirements.

[0012] According to an advantageous embodiment of the invention, an actuator, in particular an electric actuator, is provided for adjusting the base plate about the inclination axis. By means of the actuator, for example an electric actuator, a high degree of comfort can be achieved when adjusting the inclination of the base plate with the foot support surface and / or the pedal arrangement.

[0013] According to an advantageous embodiment of the present invention, the base plate is biased into the upwardly tilted position by a spring device. This allows for a simple design of the tilt-adjustable base plate, since the base plate is pre-biased into the upwardly tilted position by the spring device, and the operator can deflect the base plate downwardly about the tilt axis by placing their foot on the base plate against the force of the spring device to accommodate ergonomic requirements.

[0014] According to an advantageous embodiment of the present invention, the spring device is configured as a compression spring, in particular a gas compression spring. By means of the compression spring (eg gas compression spring), it is possible to load the base plate into the upper inclined position with very little structural effort.

[0015] According to an advantageous embodiment of the invention, a locking device is provided for fixing the base plate in the tilted position. By means of the locking device, the base plate, which is upwardly loaded by the spring device about the tilt axis, can be locked in a desired tilted position that is ergonomic for the operator in a simple manner.

[0016] According to an advantageous embodiment of the invention, the locking device is configured as a latching device. By means of the latching device, a base plate adjustable in inclination in a latching manner can be locked in a desired, ergonomically inclined position for the operator with low structural complexity.

[0017] According to an advantageous embodiment of the present invention, the latching device comprises at least two latching grooves arranged on the base plate and a latching element operatively connected to the latching grooves. Since the latching device comprises at least two latching grooves arranged on the base plate and a latching element operatively connected to the latching grooves, a latching device that locks the inclination of the base plate can be formed with minimal structural effort.

[0018] According to an advantageous embodiment of the present invention, the latch element is arranged on the joystick that is arranged in the driver's station. Therefore, the operator who is sitting on the driver's seat can manipulate the latch element by the joystick (for example, with hands or feet) in a simple manner.

[0019] According to an advantageous embodiment of the present invention, the operating lever is arranged in the driver's station so as to be adjustable about a pivot axis between a release position and a locking position. In the locking position of the operating lever, the latching element preferably engages with a latching groove, thereby locking the inclination of the base plate. In the release position, the latching element preferably disengages from the latching groove, thereby allowing the base plate to be pivoted about the tilt axis and its inclination to be adjusted.

[0020] According to an advantageous embodiment of the invention, the actuating lever is loaded into the locking position by a spring device with regard to simple operation and high functional reliability.

[0021] According to an advantageous embodiment of the present invention, the pivot axis of the joystick is arranged parallel to the tilt axis of the base plate.Thus, the joystick can be manipulated clearly and simply between the release position and the locking position by an operator sitting on the driver's seat.

[0022] According to an advantageous embodiment of the present invention, a stop for determining an upper tilt position is formed between the base plate and the driver's seat. Thus, the upper tilt end position of the base plate with the pedal arrangement can be formed simply.

[0023] According to an advantageous embodiment of the present invention, operating elements of the deadman switch and / or horn device are arranged on the floor, so that the operator sitting in the driver's seat can easily operate the operating elements of the deadman switch and / or horn device with one foot.

[0024] According to an advantageous embodiment of the invention, the industrial truck is designed as a counterbalanced forklift or a reach truck. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] exist Figure 1 1 shows a view of a driver's station F of an industrial truck 1 according to the invention.

[0035] In the exemplary embodiment shown, the industrial truck 1 is designed as a reach truck 2 .

[0036] The driver's station F has a driver's seat 5 and a floor 6. The driver's seat 5 is arranged on a cover 7 similar to a hood. The driver's seat 5 can be on the cover 7 (such as Figure 1 The driver's seat 5 is height-adjustable in the vertical direction H (as indicated by the arrow H) and / or adjustably arranged in the seat longitudinal direction L. In the illustrated embodiment of the reach truck 2 , the seat longitudinal direction L of the driver's seat 5 is located in the vehicle transverse direction Q of the reach truck 2 .

[0037] The floor panel 6 is arranged in front of the driver's seat 5 (as viewed in the longitudinal direction of the seat L).

[0038] The operator sitting on the driver's seat 5 can place or support his feet on the base plate 6. For this purpose, the base plate 6 has a foot support surface 100 on the upper side. The foot support surface 100 is preferably designed so that the operator sitting on the driver's seat 5 can support his feet on the foot support surface 100.

[0039] In the embodiment shown in the figure, a pedal device 10 is also arranged on the bottom plate 6. Figure 2 Shown in detail.

[0040] In the illustrated embodiment, the pedal device 10 includes an accelerator pedal 11 and a brake pedal 12. The accelerator pedal 11 and the brake pedal 12 can be operated by an operator sitting in the driver's seat 5 with both feet and pressed downward relative to the floor 6.

[0041] The pedal arrangement 10 is arranged non-adjustably on the base plate 6. Such an arrangement is to be understood as meaning that, apart from the actuation movement of the accelerator pedal 11 and the brake pedal 12, the two pedals 11, 12 cannot be adjusted or adjusted relative to the base plate 6.

[0042] The base plate 6 is arranged in the driver's station F, and its inclination can be adjusted about an inclination axis 15 .

[0043] The pedal device 10 is arranged in the front area of ​​the floor panel 6 facing away from the driver's seat 5. The tilt axis 15 is arranged in the rear area of ​​the floor panel 6 facing the driver's seat 5. The tilt axis 15 is configured as a horizontally arranged tilt axis, which is arranged perpendicular to the seat longitudinal direction L of the driver's seat 5.

[0044] The base plate 6 is arranged on the driver's station F so that its tilt angle about the tilt axis 15 can be adjusted continuously or in a latching manner (or in steps). In the illustrated embodiment, the base plate 6 is arranged so that its tilt angle about the tilt axis 15 can be adjusted in a latching manner and is thus arranged on the driver's station F in an adjustably manner.

[0045] exist Figure 3a The base plate 6 is shown in a lowered inclined position. Figure 3c The base plate 6 is shown in an upward tilted position. Figure 3b The bottom plate 6 is shown in the middle tilted position. Figures 3a to 3c As shown, by adjusting the floor panel about the tilt axis 15 , the angle of attack of the floor panel 6 and thereby the angle of attack of the foot support surface 100 and / or the pedal arrangement 10 relative to the driver's seat 5 can be changed.

[0046] The following will refer to Figures 4 to 6 The structure of the base plate 6 whose inclination can be adjusted around the inclination axis 15 will be described.

[0047] The base plate 6 is preferably fixed to the driver's station F via a hinge 20 forming the tilting axis 15. For this purpose, the hinge 20 is fastened to the base plate 6 by means of a fastening screw 21 and to a fixed console component 23 of the driver's station F on board by means of a fastening screw 22.

[0048] The base plate 6 is biased into the upper tilted position by a spring device 25 . In the illustrated embodiment, the spring device 25 is designed as a compression spring 26 , for example a gas compression spring 27 .

[0049] In the illustrated embodiment, the spring device 25 is arranged vertically below the base plate 6. The spring device 25 is supported at a first end on a fastening element 30 (e.g., a flange plate) arranged on the console part 23 and is connected at a second end to a fastening element 31 (e.g., a flange plate) arranged on the underside of the base plate 6.

[0050] In order to lock the tilt angle of the base plate 6 about the tilt axis 15 , a locking device 40 for fixing the tilt of the base plate 6 is provided.

[0051] In the illustrated embodiment, the locking device 40 is designed as a latching device 41 .

[0052] The latching device 41 has at least two latching grooves 45a, 45b, 45c, 45d, 45e arranged on the base plate 6 and a latching element 46 that can be operatively connected and engaged with the latching grooves 45a, 45b, 45c, 45d, 45e.

[0053] In the exemplary embodiment shown, the latching grooves 45 a , 45 b , 45 c , 45 d , 45 e are designed as elongated hole-like grooves, with which the latching element 46 , designed as a pin or bolt, can engage.

[0054] In the exemplary embodiment shown, the latching recesses 45 a , 45 b , 45 c , 45 d , 45 e are formed in a plate 47 which is arranged on the underside of the base plate 6 .

[0055] In the illustrated embodiment, the latching element 46 is arranged on an operating lever 50 provided in the driver's station F.

[0056] The latching grooves 45 a , 45 b , 45 c , 45 d , 45 e respectively determine different tilting angles of the base plate 6 about the tilting axis 15 and thus different angles of attack of the base plate 6 provided with the pedal arrangement 10 .

[0057] In the illustrated embodiment, the operating lever 50 is arranged in the driver's station F so as to be adjustable about a pivot 51 between a release position and a lock position. To this end, the operating lever 50 is arranged on a fixed vehicle console component 52 of the driver's station F near a front end area of ​​the floor 6 facing away from the driver's seat 6 so as to be pivotable about the pivot 51. In the illustrated embodiment, the pivot 51 of the operating lever 50 is arranged parallel to the tilt axis 15 of the floor 15.

[0058] In the illustrated embodiment, a stop 60 for determining the upper tilt position is constructed between the base plate 6 and the driver's station F. In the illustrated embodiment, the stop is constructed as a stop pin 61 arranged on the plate 47. When the base plate 6 swings upward around the tilt axis 15, the stop pin abuts against the console component 52 of the driver's station F, thereby limiting the upper tilt position of the base plate 6.

[0059] With the help of Figure 4 and Figure 5 The function of the base plate 6 of the present invention will be explained.

[0060] exist Figure 4 In the upper figure, the base plate 6 is in a downwardly inclined position, wherein the operating lever 50 is in a locked position and the operating lever 50 engages with the uppermost locking groove 45a of the base plate 6 with the locking element 46.

[0061] By following Figure 4Arrow P1 in the lower figure deflects the operating lever 50 about the pivot 51 so that the operating lever 50 is operated to the release position, in which the locking elements 46 of the operating lever 50 are disengaged from the corresponding locking grooves 45a to 45e of the base plate 6.

[0062] like Figure 5 As shown in the figure above, in the release position of the operating lever 50, the base plate 6 is deflected upward around the tilt axis 15 under the action of the spring device 25. If the appropriate tilt position of the base plate 6 is reached, it can be adjusted according to the Figure 5 Arrow P2 in the lower figure deflects the operating lever 50 about the pivot 51 to return the operating lever 50 to the locked position, in which the latching elements 46 of the operating lever 50 engage with the corresponding latching grooves 45b-45e of the base plate 6. In the illustrated embodiment, the operating lever 50 engages with the middle latching groove 45c of the base plate 6 by being deflected back to the locked position, thereby fixing the base plate 6 at the tilt angle defined by the latching groove 45c about the tilt axis 15.
