It is important for workstations where work requires an operator to sit on a seat for quite long periods of time without a break to be configured such that they are set up in an optimum manner ergonomically for the operator in question. This means they should be equipped to allow the height of the seat to be adjusted so that the operator in question can arrange him/herself in an optimum position for performing a task or operating equipment or a vehicle. A particular aspect of stations for driving vehicles is that as well as ergonomic requirements a clear view imposes its own requirements. The relationship between the eyes of the vehicle driver and windows that allow a clear view is not arbitrary. The seat height and height of the operating console cannot therefore be changed randomly.
A foot platform is also frequently required to equip the workstation in a particularly good ergonomic manner. In particular when workstations are used by different people, a simple embodiment is inadequate as people have legs of different lengths. Foot platforms are therefore frequently equipped so that they can be adjusted individually by the operator in question.
It is therefore known to equip a foot platform for the driving position in a rail vehicle with a pivotable foot rest plate which can be adjusted manually to a pivot position suitable for the operator in question. This has the disadvantage that the operator in question must ascertain his/her optimum foot rest plate pivot position in order to adjust the foot platform accordingly when starting work in the driving position or must experiment until an optimum pivot position of the foot rest plate is reached.
It is the object of the invention to propose a foot platform with a foot rest plate mounted pivotably on a housing of the foot platform, with which the foot rest plate can be adjusted with optimum convenience using simple means.
Said object is achieved according to the invention with a foot platform with a foot rest plate mounted pivotably on a housing of the foot platform, the lower face of said foot rest plate being supported by a spring, and with mechanical detent means for locking the foot rest plate in a pivot position; the foot platform is also provided with a remote-controlled mechanical locking facility for engaging in the mechanical detent means.
Known from the internet publication is a mechanical foot platform, the foot rest plate of which is driven by a gas spring and which has a remote control facility but this known foot platform is a platform with a foot rest plate that can be adjusted in the manner of a slide using a helical gear unit.
One important advantage of the inventive foot platform is that it can be actuated in a convenient manner using simple means, as actuation of the remote controlled locking facility allows the spring to act on the foot rest plate, causing the foot rest plate to pivot upward until it is held by the feet of the operator in question in the desired optimum pivot position. Release of the locking facility causes the foot rest plate then to be set in said pivot position. This procedure is so undemanding that it can be performed by an operator without significant distraction even during the course of the actual activity. Also the inventive foot platform requires no auxiliary energy.
The spring can be configured in a number of different ways in the inventive foot platform. It is deemed particularly advantageous for the spring to be a gas spring.
Also the detent means for locking the foot rest plate can be embodied in different ways in the inventive foot platform. It is deemed particularly advantageous for the detent means to have at least one perforated plate which is fastened to the housing in the pivot direction of the foot rest plate. The locking facility also has a spring-loaded latching element in such an arrangement on the foot rest plate that it can be inserted into the holes in the perforated plate from the side. This latching element can be embodied in the manner of a snap lock or a spring-loaded plunger.
It is also deemed advantageous to position the perforated plate to the side of the foot rest plate on the housing, as this can be achieved with relatively little structural outlay.
It can also be advantageous for the detent means to have a friction lining which is fastened to the housing in the pivot direction of the foot rest plate and for the locking facility to be a spring-loaded friction element in such an arrangement that it can be moved against the friction lining from the side.
The locking facility of the inventive foot platform advantageously has a Bowden cable, as Bowden cables are widely available and are therefore economical to use.
The invention further relates to a desk of a workstation with a foot platform and aims to configure the foot platform of such a desk in such a manner that the foot platform can be adjusted conveniently to the respectively desired position in respect of the foot rest plate when an operator is seated.
To achieve this object, according to the invention the foot platform is positioned below the desk and the locking facility is fastened in an easily accessible manner to the desk at its end facing away from the foot rest plate.
Said desk is advantageous in that a seated operator can adjust the foot platform into an optimum pivot position in each instance in a simple manner by actuating the locking facility subject to the action of the spring, it being possible for this to be done without stopping work and without significant distraction from work.
The inventive desk can be used at different workstations as well as at operating stations of different types of vehicles. It is deemed particularly advantageous for the desk to be the operating console of a driving position in a rail vehicle and for the foot platform to be fastened to the base of the driving position and for the locking facility to be fastened with its end facing away from the foot platform laterally forward in the upper region of a recess of the operating console accommodating the foot platform.
To clarify the invention further
The exemplary embodiment of an inventive desk shown in
The foot platform 4 has a foot rest plate 6 arranged pivotably by means of a hinge 5 (see
As shown in particular in
To control the action of the gas spring 12, a perforated plate 17 with a number of holes 18 is fastened to the housing 10 in the direction of the pivot movement of the foot rest plate 4 to the side of the foot rest plate 4, therefore next to the foot rest plate 4. A spring-loaded latching element 19 (only shown schematically in
The latching element 19 can be part of a locking facility embodied in the form of a Bowden cable 20, as shown in
