Abstract
Description
Technical Field
[0001] The present invention relates to a driver work position unit for a reach truck, wherein the driver work position unit includes a driver work position. Background Art
[0002] A reach truck is generally configured with a vehicle chassis and a driver work position unit, and the driver work position unit can be installed and fixed on the vehicle chassis as an independent unit. The vehicle chassis includes a vehicle frame, drive wheels, load rollers arranged on wheel arms, a travel drive, a steering drive, hydraulic equipment, braking equipment, and a traction battery. On the vehicle chassis, a lift mast is movably arranged on the wheel arms in the longitudinal direction of the vehicle. Thus, the vehicle chassis has the main technical structural elements of a reach truck and is also referred to as a so-called rolling chassis.
[0003] The driver work position unit (in which the driver work position is arranged) that forms an independent unit is provided with main operating elements, such as a steering wheel, a pedal unit, operating elements, a driver's seat, and a storage box. Another function of the driver work position unit is to protect the driver in the driver work position unit, for example, against falling objects or tipping racks. For this protection function, the driver work position unit is vertically provided with a driver protection roof above. The driver work position unit provided with the driver protection roof is arranged and fixed on the vehicle chassis and is also referred to as a so-called top chassis.
[0004] In known reach trucks, the combination of the driver work position unit and the driver protection roof is composed of sheet metal elements welded to each other, such as sheet metal bends or stampings, which simultaneously form the corresponding trim elements of the driver work position unit, such as the right side wall, left side wall, front wall, and rear wall, and vertical supports are welded to these trim elements, and the vertical supports carry the driver protection roof and the driver protection roof is fixed to the vertical supports.
[0005] A reach truck composed of a vehicle chassis and a driver work position unit that forms an independent unit is known from DE 102005 012 879A1.
[0006] In reach trucks, there are significant differences in the combination consisting of the driver's workplace unit and the driver's protective roof. Due to various requirements for brand differentiation and special customer requirements, in known driver's workplace units made of sheet metal elements welded to each other (which at the same time form the trim elements of the driver's workplace unit such as the right side wall, left side wall, front wall and rear wall), some of the sheet blanks of the individual sheet metal elements forming the respective trim elements of the driver's workplace unit are usually implemented differently, such that a plurality of variants of the complete driver's workplace unit have to be formed and manufactured. In addition, the manufacturing costs of the sheet metal elements which at the same time form the trim elements are high, since the stiffness requirements and strength requirements of the driver's workplace unit can only be achieved by means of a correspondingly thick sheet thickness of the sheet metal elements and / or at the same time a complex pressing geometry of the sheet metal elements, which results in high material costs and high manufacturing costs for the driver's workplace unit. Moreover, due to the significant differences in the driver's workplace unit, high investment costs, equipment costs and setup costs are incurred during the manufacture of known driver's workplace units made of sheet metal elements welded to each other, which at the same time form the trim elements of the driver's workplace unit such as the right side wall, left side wall, front wall and rear wall. Summary of the Invention
[0007] The object on which the invention is based is to provide a driver's workplace unit of the type initially mentioned which is improved with respect to the abovementioned disadvantages.
[0008] According to the invention, this object is achieved by a driver's workplace unit having a load-bearing support structure which comprises a left load-bearing support element and a right load-bearing support element and at least one load-bearing transverse connecting element connecting the left support element and the right support element, wherein at least one non-load-bearing trim element can be detachably fixed to the load-bearing support structure.
[0009] In the sense of the invention, the support structure or the support element or the transverse connecting element is in particular regarded as a load-bearing support structure or a load-bearing support element or a load-bearing transverse connecting element which meets all the stiffness requirements, stability requirements and strength requirements of the driver's workplace unit.
[0010] The driver's workplace unit according to the invention has a modular structure by virtue of the load-bearing support structure and the trim elements detachably fixed to the support structure, which modular structure enables significant differences in the manufacture of the driver's workplace unit to be achieved in a simple manner.
[0011] Thus, according to the present invention, the driver's working position is made of a load-bearing support structure that can be manufactured simply and at low cost, such as a tube structure or a profile structure that can be fixed to the vehicle chassis. The load-bearing support structure includes a left load-bearing support element, a right load-bearing support element, and at least one load-bearing transverse connection element connecting the left support element and the right support element. Thus, the load-bearing support structure forms a "skeleton" and meets all requirements for the stiffness, stability, and strength of the driver's working position unit. For example, the need to improve stability, which is formed by corresponding customer requirements, can be advantageously adapted to the load-bearing support structure in a simple manner by means of support profiles, such as thicker wall thicknesses of tube profiles, when necessary. At least one non-load-bearing trim element is detachably fixed to the load-bearing support structure. Thus, the non-load-bearing trim element does not have to absorb and transmit any forces required for the stiffness, stability, and strength of the driver's working position unit, enabling the non-load-bearing trim element to be manufactured at relatively low cost and to be changed in a simple manner. In the present invention, the non-load-bearing trim element constituting the corresponding attachment can be implemented differently in a simple manner, for example, in terms of blank and / or shape and / or color, whereby functional and / or visual differentiation can be achieved in a simple manner. In addition, the requirements for the non-load-bearing trim element constituting the corresponding attachment are mainly of an optical nature, because the mechanical requirements for the rigidity, stability, and strength of the driver's working position unit are already fully met by the load-bearing support structure. This opens up the possibility of manufacturing trim elements at low cost from a thinner sheet thickness or from alternative materials, such as plastics. Thus, significantly more possibilities for achieving visual and functional differentiation are obtained from the customer's perspective. Therefore, with the aid of the present invention, a large difference in the driver's working position unit can be provided in a simple and cost-effective manner.
[0012] According to a preferred embodiment of the present invention, the load-bearing support structure is provided with a fixing interface by means of which the driver's working position unit can be detachably fixed to the vehicle chassis of a reach truck. Thus, the driver's working position unit formed by the load-bearing support structure can be fixed and installed on the vehicle chassis of a reach truck in a simple manner.
[0013] According to a preferred embodiment of the present invention, the trim element is configured as the left side wall and / or the right side wall and / or the rear wall of the driver's working position unit. The left side wall preferably delimits the driver's working position towards the left side of the vehicle. The right side wall preferably delimits the driver's working position towards the right side of the vehicle. The rear wall preferably delimits the driver's working position towards the rear side limit of the reach truck, and an access opening is formed in the rear wall, which can enable the driver to enter / exit the driver's working position.
[0014] According to a preferred embodiment of the present invention, the transverse connecting element is configured as a front wall. With the transverse connecting element configured as a front wall, a high stability of the load-bearing support structure can be achieved in a simple manner, and the transverse connecting element connects and reinforces the left support element and the right support element.
[0015] According to a preferred embodiment of the present invention, the transverse connecting element is configured as a front transverse support and / or a rear transverse support. With the transverse connecting element configured as a front transverse support, a high stability of the load-bearing support structure can be achieved in a simple manner, and this transverse connecting element connects and reinforces the left support element and the right support element. With the transverse connecting element configured as a rear transverse support, a high stability of the load-bearing support structure can be achieved in a simple manner, and this transverse connecting element connects and reinforces the left support element and the right support element. In addition, through the corresponding configuration of the rear transverse support, an ergonomically favorable access opening can be provided in a simple manner, and this access opening enables the driver to enter / exit the driver's working position ergonomically.
[0016] According to a preferred embodiment of the present invention, the trim element is detachably fixed to the load-bearing support structure by means of at least one threaded connection and / or at least one clip connection and / or at least one hook connection. In particular, a combination of multiple of these connection types can also be considered. Thus, for example, the trim element can be detachably fixed to the load-bearing support structure by means of a hook connection and a threaded connection, whereby a simple and rapid installation of the trim element can be achieved. For this purpose, the load-bearing support structure is provided, for example, with riveted nuts for fixing screws or receiving holes at different positions as interfaces for the trim element to be installed.
[0017] According to a preferred embodiment of the present invention, the load-bearing support structure is provided with a fixing interface, on which at least one of the following components is fixed:
[0018] - driver's seat
[0019] - steering operation unit, in particular steering wheel
[0020] - arm support, in particular armrest
[0021] - floor panel, in particular floor panel with at least one pedal
[0022] - operating element, in particular at least one operating lever
[0023] - display element, in particular display screen
[0024] - electronic device bracket
[0025] Thereby, the above-mentioned components can be arranged and fixed to the load-bearing support structure in a simple manner.
[0026] According to a preferred embodiment of the present invention, the load-bearing support structure is provided with a driver's protective roof.
[0027] The driver's protective roof can be rigidly connected to the load-bearing support structure, for example, by welding.
[0028] According to a preferred embodiment of the present invention, the left support element and the right support element are respectively provided with fixing interfaces in the upper vertical region, by means of which the driver's protective roof is detachably fixed to the support element. Thus, it can be realized in a simple manner that different variants of the driver's protective roof, such as a support roof with a metal support or a glass roof, are fixed to the load-bearing support structure, so that the differences in the driver's working position unit in different implementation aspects of the driver's protective roof can also be provided in a simple manner.
[0029] According to a preferred embodiment of the present invention, the left load-bearing support element and the right load-bearing support element respectively include a front vertical support member and a rear vertical support member connected to each other by means of at least one longitudinal support member. Therefore, the left load-bearing support element and the right load-bearing support element form a ladder-shaped or truss-shaped support structure, which can be manufactured in a simple manner so as to meet the mechanical requirements for the stiffness, stability, and strength of the driver's working position unit.
[0030] According to a preferred embodiment of the present invention, the front vertical support members and the rear vertical support members of the right support element and the left support element are connected to each other by means of an upper longitudinal support member in the upper vertical region, wherein the upper longitudinal support member is provided with a fixing interface, by means of which the driver's protective roof is detachably fixed to the support element. Thus, a simple structure of the two support elements with few components is achieved, because the vertical support members rise vertically so that a fixing interface can be constructed on the upper longitudinal support member, on which the driver's protective roof is detachably fixed to the support element.
[0031] According to an alternative and equally preferred embodiment of the present invention, the front vertical support members and the rear vertical support members of the right support element and the left support element are connected to each other by means of an upper longitudinal support member in the upper region, wherein the left load-bearing support element and the right load-bearing support element respectively include load-bearing elements fixed to the upper longitudinal support member, and wherein the load-bearing elements are provided with fixing interfaces in the upper vertical region, by means of which the driver's protective roof is detachably fixed to the support element. Therefore, the left load-bearing support element and the right load-bearing support element are respectively provided with load-bearing elements extending vertically upward, and the driver's protective roof is detachably fixed to the load-bearing elements. Thus, the modularity and differences of the driver's working position unit are further improved, because load-bearing elements with different configurations can be used on the two support elements in a simple manner.
[0032] According to a preferred embodiment of the present invention, the load-bearing element is configured as a tubular profile. With the load-bearing element configured as a tubular profile, the mechanical requirements for the rigidity, stability, and strength of the driver protection roof fixed to the driver's work position unit can be met in a simple manner.
[0033] According to a preferred embodiment of the present invention, the vertical support members are respectively configured as tubular profiles or angle profiles. Thus, the mechanical requirements for the rigidity, stability, and strength of the driver's work position unit can be met in a simple manner.
[0034] According to a preferred embodiment of the present invention, the longitudinal support member is configured as a tubular profile or an angle profile. Thus, the mechanical requirements for the rigidity, stability, and strength of the driver's work position unit can be met in a simple manner.
[0035] According to a preferred embodiment of the present invention, the left load-bearing support element and the right load-bearing support element are respectively configured as welded structures. In such a welded structure, the front vertical support member, the rear vertical support member, and at least one longitudinal support member constituting the left or right support element are welded to each other. Thus, the mechanical requirements for the rigidity, stability, and strength of the driver's work position unit can be met in a simple manner and the corresponding support elements can be manufactured in a simple manner. Alternatively, it can also be considered to implement the left or right support element composed of the front vertical support member, the rear vertical support member, and at least one longitudinal support member as a threaded structure in which the vertical support member and the longitudinal support member are screwed together or as a plug-in structure in which the vertical support member and the longitudinal support member are connected to each other through a plug-in connecting member.
[0036] According to a preferred embodiment of the present invention, the front wall is connected to the left load-bearing support element and the right load-bearing support element by means of a welded connection. Thus, the mechanical requirements for the rigidity, stability, and strength of the driver's work position unit can be met in a simple manner.
[0037] According to a preferred embodiment of the present invention, the front transverse support member and / or the rear transverse support member are respectively connected to the left load-bearing support element and the right load-bearing support element by means of a threaded connection or a welded connection. Thus, the mechanical requirements for the rigidity, stability, and strength of the driver's work position unit can be met in a simple manner.
[0038] According to a preferred embodiment of the present invention, the transverse connecting element is configured as a tubular profile or an angle profile.
[0039] According to a preferred embodiment of the invention, the non-load-bearing trim element is configured as a sheet member, in particular a metal sheet, or as a plastic member, in particular a plastic sheet. Since the trim element does not absorb and transmit any forces required for the stiffness, stability and strength of the driver's work position unit, the trim element can be constructed in a cost-effective structural form as a sheet member, in particular a thin metal sheet, or a plastic member, in particular a plastic sheet.
[0040] The invention also relates to a reach truck, comprising a vehicle chassis and a driver's work position unit according to one of the preceding claims, wherein the vehicle chassis comprises running gear wheels, a running drive and a steering drive, and wherein the driver's work position unit can be detachably fixed to the vehicle chassis.
[0041] The reach truck has the advantages already described with regard to the driver's work position unit.
[0042] The invention has a series of advantages.
[0043] The load-bearing support structure of the driver's work position unit constitutes a "skeleton" consisting of tubular profiles and / or angle profiles. The load-bearing support structure can be modularly extended with non-load-bearing trim elements that are detachably fixed to the load-bearing support structure, and these trim elements can be different.
[0044] The load-bearing support structure is divided into sections that can be different by means of a left support element, a right support element and at least one transverse connecting element, whereby different driver's work position units can be assembled and manufactured in a simple manner.
[0045] The invention enables cost-effective manufacture of the driver's work position unit.
[0046] Cost-effective and commonly available standard profiles can be used as the tubular profiles and / or angle profiles for the load-bearing support structure.
[0047] The driver's work position unit according to the invention can be constructed in a simple manner such that the mechanical requirements for the rigidity, stability and strength of the driver's work position unit are met. Higher requirements, such as higher stability, can be easily adapted by using thicker tube material.
[0048] The driver's work position unit according to the invention provides a high degree of flexibility in a simple manner for various customer, design and market requirements.
[0049] The driver's working position unit according to the invention can also be replaced simply and at low cost, for example, replacing trim elements subsequently, or simply and at low cost repairing damaged trim elements, for example, after an accident. Therefore, the driver's working position unit according to the invention enables simple subsequent modular retrofitting. The modular structure of the driver's working position unit enables simple repair, especially when the vehicle body is damaged, by replacing the damaged trim elements.
