ARRANGEMENT IN A DRIVER'S CAB OF A WORKING MACHINE

BACKGROUND OF THE INVENTION The invention relates to an arrangement for fastening control elements to a driver's cab of a work machine.

The invention further relates to a driver's cab of a work machine having at least side panels, a windshield and at least one control element.

[0003] More and more different control means are needed in work machines. The systems of work machines are more complex than before and the machines are often equipped with various auxiliary devices that make work tasks easier. That is why there are many different selector and control elements as well as screens in the driver's cab of work machines, the positioning of which in the driver's cab is demanding. It is found that today's arrangements are not sufficient.

BRIEF DESCRIPTION OF THE INVENTION It is an object of the present invention to provide a novel and improved arrangement for fastening various control elements to a driver's cab of a work machine and a driver's cab of a work machine.

The arrangement according to the invention is characterized in that the arrangement: at least one elongated and substantially horizontal fastening rod; first fastening means for fastening the fastening rod to the driver's cab of the work machine; at least one control; and second fastening means for fastening said at least one control element to said at least one fastening rod.

The driver's cabin according to the invention is characterized in that the driver's cabin has at least one elongated and substantially horizontal fastening rod; that the fastening rod is fastened between the side panels of the driver's cab; and that the at least one control element is fastened to the fastening rod by second fastening means.

The idea of the solution described is that various control elements of the work machine are attached to a rod-like element in the driver's cab of the work machine. This fastening rod can be arranged horizontally on the front part of the driver's cab, the control elements to be fastened thereon being easily accessible and visible to a user.

The solution described has the advantage that an elongated mounting rod offers a large number of options for mounting various controls. Furthermore, it is easy and quick to fasten control elements in the desired position and in the desired position on the rod-like element by means of the second fastening means. The fastening rod allows the fastening to be carried out more freely than before. The solution thus improves flexibility and allows a larger number of control elements in the driver's cabin. In addition, it is easy to make changes to the equipment and layout of the driver's cab later, since they do not require changes to the equipment board or other structures in the driver's cab. This means that the driver's cabin and its equipment can be easily updated.

The idea of one embodiment is that the second fasteners are quick fasteners that allow the control to be attached and detached without disassembling the structures. Because of such quick fasteners, it is easy to attach and detach various controls, and to change their location and position. Various quick fasteners that can be used in this embodiment are in rei1 / 9

AT 15 641 U1 2018-03-15 Austrian patent office rather selection available.

The idea of one embodiment is that the second fastening means are quick fastening means which allow the control element to be attached and detached and its position and position to be adjusted without tools. Fastening without tools makes assembly and adjustment particularly easy and quick.

The idea of an embodiment is that the second fastening means have at least two clamping elements movable with respect to one another, which are arranged against the surfaces of a fastening rod and then clamped together and can be closed in the clamped position. The clamping elements can be deformed such that they are adapted to the shape of the outer surface of the fastening rod, i. that is, if the coupling rod has a round outer surface, the clamping elements are provided with curved clamping surfaces. The clamping and closing force can be brought about, for example, with screw means, wedge surfaces or other suitable mechanisms. Such clamping elements enable attachment at any point and in any position on the fastening rod. Furthermore, the second fastening elements can have coupling elements for fastening to a control element. A coupling ball, for example, can serve as the coupling element, the control element having a recess receiving the ball, or a recess adapter being arranged on the control element. The position of the control element can be adjusted in many ways within limits and directions permitted by the sphere. By clamping the recess and influencing its interior volume, a locking between the ball and the recess is achieved.

The idea of an embodiment is that the fastening rod has no predetermined fastening points for a control element, and any point on the fastening rod can serve as a fastening point. In this case, the control element can be freely moved in the longitudinal direction of the fastening rod to any fastening point and closed in place with the second fastening means. Thanks to this solution, the flexible positioning of the control elements is possible. The user of the work machine can move the controls laterally to the exact desired location, which improves work ergonomics and effectiveness.

The idea of an embodiment is that the length of the fastening rod is at least the width of the inner part of the driver's cabin. If the mounting bar is curved, angular or follows the front of the driver's cab, its length is greater than the width of the inside of the driver's cab. Such a relatively long fastening rod offers many fastening options.

The idea of an embodiment is that the control element is a display device. The display device can be, for example, a display panel, a computer display, a navigator display, a screen of an on-board computer of a work machine or a screen of systems and auxiliary devices of a work machine. Using a display device, the user can receive various control information and information about system states of the work machine. The display device can also be a means for entering information into the system of the work machine and for selecting options during use. The display device can thus be a touch screen.

The idea of an embodiment is that the control element is a control device. The control device can be, for example, a steering wheel, a control lever, a trackball or an electrical switch module. With the control device, the user can give control commands relating to the driving of the work machine and the work task to be performed to the systems of the work machine.

The idea of an embodiment is that the control element is an electronic terminal. The electronic terminal can be, for example, a data transmission device, a radio telephone, a mobile phone, a navigation device, a measuring device or a computer. With the

2/9

AT 15 641 U1 2018-03-15 Austrian patent office electronic device, the user can be in connection with external information systems of the work machine and receive work instructions and positioning information.

The idea of an embodiment is that the driver's cab has at least one elongated and substantially horizontal cable duct, a cable strip or a similar cable support in the vicinity of the fastening rod, so that the cables of one or more control elements which are fastened to the fastening rod, in Cable duct can be arranged. Thanks to the cable duct, various electrical lines and data transmission cables can be checked and practically laid. The cable duct thus facilitates the assembly of the control elements and the subsequent changes in their positions.

The idea of one embodiment is that the driver's cabin has a switchboard panel below the windshield, in which there is a cable duct, a cable strip or a similar element for the lines of the control elements coupled to the fastening rod. If any control element, which is coupled with lines to an electrical or information system, is mounted anywhere on the fastening rod, the lines leading to the control element can be easily guided from the control element into the cable duct exactly at the point where it is located the control is located. The cable duct can be located, for example, below the switchboard panel or near its lower part.

The idea of an embodiment is that the work machine is a reach stacker and the driver's cabin is a driver's cabin of a reach stacker. The reach stacker has a frame, a drive device, wheels and a boom, which is provided with a load handling device. The boom lies in the longitudinal direction of the frame and is coupled with a joint to a fastening projection on the rear part of the frame. The boom can be raised and lowered with lifting cylinders or the like and the boom can be extended and shortened telescopically. The reach stacker can be used for lifting, transporting and stacking wood, containers, steel rolls or any other loose material or transport units. Many different controls and indicators may be needed to control the rack, boom, load handling device, and other systems of the reach stacker. In the driver's cabin of the reach stacker, there may also be positioning means, data transmission means for communication and for receiving and sending functional instructions relating to the work line. All such devices can be attached to the mounting rod described in this application so that they can be reached by the driver.

The idea of an embodiment is that the driver's cab also has one or more substantially vertical fastening rods for fastening the control elements in addition to the one or more substantially horizontal fastening rods. The vertical bars can be attached to roof rack pillars on the sides of the cab, for example.

The idea of an embodiment is that the ends of the fastening rod are provided with fastening flanges. Thus, the fastening of the fastening rod to the side panels is simple and stable. The mounting flanges can have openings for screw mounting.

The idea of an embodiment is that the first fastening means of the fastening rod have one or more vertical rods with which the fastening rod is supported on the floor of the driver's cabin.

The idea of an embodiment is that the first fastening means of the fastening rod have one or more coupling rods with which the fastening rod is supported on the switchboard panel or the roof pillars supporting the roof of the driver's cabin.

The idea of an embodiment is that the first fastening means of the fastening 3/9

AT 15 641 U1 2018-03-15 Austrian

Patentamt supply rod have means for adjusting the position of the fastening rod in at least two alternative positions. In conjunction with the fastening means, means for stepless adjustment can also be used. In this case it is possible to influence the height of the fastening rod.

The idea of an embodiment is that the outer surface of the cross-sectional profile of the fastening rod is round or substantially round. The fastening rod can thus consist of a round tube or a round rod.

The idea of an embodiment is that the fastening rod is a tubular, hollow piece.

The idea of an embodiment is that the fastening rod is an elongated, substantially straight piece, which is arranged between the inner walls, side panels or the like of the driver's cab.

The idea of an embodiment is that the fastening rod is an elongated, curved piece. The mounting bar may be bent such that its central portion extends forward in the cab and closer to the windshield of the cab than the mounting points and other portions of the mounting bar.

The idea of an embodiment is that the fastening rod is an elongated, bent piece, which has in its central section a straight section which is substantially parallel to the line running over the fastening elements at the ends of the fastening rod; and that the two end portions of the fastening rod have inclined portions which are in an angular position with respect to said line and the middle part of the fastening rod. In this case, the fastening rod is an angular piece which is curved in some areas and which extends closer to the windshield in the front part of the driver's cab than at its ends.

The idea of an embodiment is that the fastening rod is an elongated, curved piece that has a continuous curved shape instead of an angular shape. The fastening rod can have several radii of curvature so that it has a desired curved shape.

The embodiments described above and their features can optionally be combined with one another in order to achieve different combinations.

DETAILED DESCRIPTION OF THE INVENTION FIG. 1 shows a reach stacker 1, which is an example of a work machine 2, in the driver's cab of which the solution described in this application can be used. Other possible working machines in which the solution can be used include forestry machines, agricultural machines, earth-moving machines, transport and conveying devices and cranes.

A reach stacker 1, often also referred to as a stacker 1, is a load handling machine with which a load can be gripped, lifted and transported. In some cases, the load can also be stacked with it. The reach stacker 1 has a frame 3, a drive device 4, wheels 5 and a boom 6 which is provided with a load treatment device 7. The boom 6 is located above the frame 3 in the longitudinal direction and is coupled with a joint 8 to a fastening projection 9 or fastening approaches on the rear part of the frame 3. The boom 6 can be raised and lowered R with lifting cylinders 10 or similar actuators and the boom 6 can be extended and shortened L telescopically.

The reach stacker 1 also has a driver's cabin 11, in which actuators, display devices and other control elements required for the control and use of the machine are located. This means that manual controls such as a steering wheel, control switches, control levers and pointer devices can be located in the reach of the user in the driver's cabin of the reach stacker. Furthermore, positioning means, data transmission means and computer display fields can be present in the driver's cabin for the user. All of the above-mentioned and similar devices can be attached to the substantially horizontal mounting rod in the driver's cab 11 in such a way that they are easily accessible and visible to the user. In addition, with the attachment described in this application, the location and mutual positions of these devices can be easily changed.

From Figure 2, a driver's cabin 11 can be seen, which has a windshield 12, a roof 13, side panels 14, a rear panel 15 and a door 16. In the front part of the driver's cab 11 there is a fastening rod 17, which is identified by a dashed line. A control element 18 is connected to the fastening rod 17 by means of second fastening means 19.

In Figure 3, the mounting rod 17 is marked for clarity with a dashed line. The fastening rod 17 can be an elongated rod-like member which is fastened between the side panels of the driver's cab or the interior structures of the driver's cab, being transverse to the direction of travel of the working machine and essentially in a horizontal position. The fastening rod can curve onto the windshield 12 and have end parts 17a and a middle part 17b. The shape of the fastening rod 17 can follow the switchboard panel 20, which typically curves in front of a driver's seat 21. Figures 2 to 4 also show roof rack columns 22.

The solution shown in Figure 4 differs from Figure 3 in that the mounting rod 17 is not angular, but curves forward with radii of curvature.

FIG. 5 illustrates the driver's view from the driver's cab 11, which is provided with the fastening rod 17 described in this application and one or more control elements 18 attached to it. It can be seen from FIG. 5 that in the vicinity of the fastening rod 17 there can be a cable duct 23 in which cables 24 and lines required for the control elements 18 can be laid. The cable duct 23 can be located in the structures below the fastening rod 17, for example in the switchboard panel or below. Alternatively, the cable duct 23 can be a separate object which is arranged in the immediate vicinity of the fastening rod. Instead of the cable duct 23, a cable strip, a cable support or a similar link can be used to support and hold the lines together. Figure 5 also shows that in some cases the driver's cabin

In addition to the horizontal fastening rod 17, the patent office can also have one or more additional vertical rods 24 which also enable the fastening of control elements 18.

A possible solution for fastening the fastening rod 17 to the driver's cabin 11 is visible from FIG. The first fastening elements 25 can be located at both ends of the fastening rod 17 and can have fastening flanges or similar fastening surfaces which enable fastening to the opposite inner side surfaces of the driver's cabin. Alternatively, the attachment bar 17 can be attached to the floor or other structures of the driver's cab with one or more coupling bars 26.

In Figure 5 is also illustrated with arrow A that the position of the control elements 18 in the longitudinal direction of the mounting rod 17 can be freely selected, and it is also easy to set this position.

The second fastening means 19 shown in FIG. 6 has two halves 27a and 27b which can be clamped to the outer surface of the fastening rod 17 with clamping elements 28 and closed immovably. The fastening enables the second fastening means 19 to be rotated in the direction B and moved in the longitudinal direction of the fastening rod 17.

The second fastening means 19 can also have one or more joints 29 or, for example, a lockable ball fastening, which offers further possibilities for adjustment. As can be seen, the mounting rod 17 can be tubular.

In Figure 6, arrows C and D also illustrate that the fastening of the fastening rod can be arranged so that the fastening rod 17 can be moved into a desired position. This further increases the options for adjusting the ergonomics of the driver's cab.

In some cases, the features presented in this application can be used as such and regardless of the other features. On the other hand, the features shown in this application can optionally be combined with one another to form different combinations.

The drawings and the associated description are only intended to illustrate the idea of the invention. The details of the invention may vary within the scope of the claims for protection.
