Definitions

  • the invention relates to a control switch for operating a crane according to the preamble of claim 1.
  • Such a control switch is known from the brochure "CLX CHAIN HOIST - CRANE FOR EVERYDAY LIFTING" from Konecranes.
  • This control switch is designed as a wired pendant control switch and comprises an elongated housing extending in its longitudinal direction.
  • Several operating elements are arranged on a front side of the housing in order to control various functions of a crane which can be connected to the control switch.
  • four control elements designed in the form of buttons and intended for crane and trolley travel are combined in a cruciform arrangement to form a substantially diamond-shaped first control panel.
  • this cruciform arrangement there is a second control panel with two further button-shaped control elements, which are provided to control a lifting mechanism for lifting and lowering a load.
  • the controls for the hoist are arranged one behind the other in the longitudinal direction of the housing and in this respect vertically one above the other.
  • a third control panel is provided, above which an emergency stop button with an actuation direction oriented perpendicular to the front is arranged.
  • the opposite longitudinal sides of the housing which delimit the front, have a parallel course to one another in the area of the first control panel and, in the area of the second and third control panel, in addition to the emergency stop button, their otherwise constant distance only in the area of the second control panel and in the area between the first and the second control panel is reduced.
  • the long sides of the housing in the area of the second control panel jump back relative to their course in the area of the first and third control panel and the emergency stop button and in this respect towards one another, the transitions of the long sides between the first and second control panel each having an oblique course exhibit.
  • control switch for operating a crane is known, the control elements arranged on its housing are arranged in pairs next to one another and in a row with one another with respect to the longitudinal direction of the housing.
  • the object of the invention is to further develop a generic control switch such that it has improved ergonomic properties for particularly comfortable and safe crane operation.
  • a control switch for operating a crane which comprises a housing extending in a longitudinal direction, on the front side delimited by two longitudinal sides of which a first control panel with at least one control element is arranged, in particular for controlling at least one drive for horizontal crane movements, whereby on the Front of the housing, a second control panel with an emergency stop button and a third control panel with two controls, in particular for controlling vertical crane movements, are arranged, in terms of its ergonomic properties for a particularly comfortable and safe crane operation by improving that the long sides in the area of the first control panel have a curve that is biconvex to one another in the longitudinal direction of the housing and thus, in particular, curved outward.
  • the correspondingly biconvex curved longitudinal sides in the area of the first control panel viewed in the longitudinal direction of the housing, extend away from the longitudinal direction and then again towards the longitudinal direction.
  • the first control panel can be diamond-shaped in particular.
  • the first control panel comprises at least two control elements which are arranged one above the other along a longitudinal axis of the first control panel running parallel to the longitudinal direction of the housing and / or alongside one another along a transverse axis of the first control panel running transverse to the longitudinal direction of the housing.
  • a vertex of each of these - from the outside, convex and in this respect biconvex to each other - curved, in particular rounded, sections of the long sides is located at the level of the at least one control element or at the level of the control elements arranged alongside one another along the transverse axis and / or at the level of the between the transverse axis extending along the longitudinal axis of the control elements.
  • the apexes are consequently at the level of the corners of the diamond-shaped first control panel opposite one another in the transverse direction of the housing.
  • the first control panel can also be reached particularly well by the thumb of the hand of a person operating the control switch in the area below the biconvex course of the long sides.
  • the first control panel is designed in particular in such a way that up to four control elements for horizontal crane movements or for controlling the at least one drive for the horizontal crane movements, in particular a crane travel and / or trolley travel of the crane, cross-shaped on the, in particular diamond-shaped, first control panel within the control panel can be arranged.
  • each control element of the first control panel - as will be described in more detail with reference to the figures - is arranged in a corner of an imaginary rhombus of the diamond-shaped first control panel, the intersecting diagonals of this rhombus of the longitudinal axis and transverse axis of the correspond to the first control panel, of which the longitudinal axis is parallel and the transverse axis is corresponding are aligned transversely to the longitudinal direction of the control switch or its housing.
  • the first control panel has only one control element for horizontal crane movements or for controlling the crane travel and / or trolley travel or associated drives
  • the multifunctional control element in particular can thus also be arranged centrally between the long sides and in particular on an intersection of the diagonals of the imaginary diamond. In this case, however, no control elements are arranged in the corners of the imaginary diamond.
  • the control switch or its housing including the courses of the long sides, the arrangement of the control panels and the associated control elements, has a mirror-symmetrical shape with respect to an imaginary plane that is perpendicular to the front and contains the longitudinal axis direction of the control switch or its housing. Due to the mirror symmetry, the control switch can be gripped and held comfortably and securely by left-handed and right-handed people in the same way.
  • a second control panel with an emergency stop button and a third control panel with two control elements are provided on the front of the housing between the long sides.
  • the control elements of the third control panel can preferably be used to control a drive for vertical crane movements, in particular a hoist, of a crane that can be connected to the control switch.
  • the first control panel is preferably arranged between the second control panel and the third control panel.
  • the third control element preferably comprises two control elements for a lifting mechanism of the crane, which are arranged one behind the other in relation to the longitudinal direction of the control switch or its housing.
  • This configuration makes it possible to operate a crane in a particularly ergonomic and at the same time particularly intuitive manner, as a result of which safety in crane operation can be further increased.
  • the control elements of all control panels are preferably designed as buttons, in particular as push buttons.
  • the long sides of the housing also have a biconvex curve in the longitudinal direction of the housing in the area of the second control panel.
  • the longitudinal sides in the region of the second control panel viewed in the longitudinal direction of the housing, also extend away from the longitudinal direction and then again towards the longitudinal direction.
  • the long sides in the area of the second control panel thus have a convex shape when viewed from the outside, just as the sections of the long sides in the area of the first control panel have a convex shape.
  • a radius of curvature of the convex shape in the area of the second control panel is preferably greater than a radius of curvature of the convex shape in the area of the first control panel.
  • the ergonomic properties of the control switch according to the invention are further optimized by these convex or round and, in particular, curved profiles of the long sides, seen from the outside.
  • a rear side of the housing of the control switch opposite the front side has a profiled contour in the area of the first control panel and / or in the area of the third control panel.
  • the profiled contour can particularly advantageously have at least one projection which is raised compared to the rear.
  • the projection which preferably extends perpendicular to the longitudinal direction of the control switch, is provided so that a person operating the control switch can place the index finder of one of his hands on it at least in sections. In this way, an ergonomically advantageous position of the control switch in the hand can be brought about, in which the thumb of the respective hand can comfortably reach the respective, in particular the first or third, control panel and actuate the operating elements there.
  • the control switch can also be supported in an advantageous manner in particular on a section of the middle finger in the encompassed state. Without the correspondingly profiled contour or Otherwise, the operator would have to apply an increased holding force in order to prevent the control switch from sliding through the hand, which would also impair the accessibility of the respective control panel.
  • the first control panel and the third control panel are arranged together in a recess that recesses relative to the front of the housing.
  • the arrangement of the first and third control panel in this recess has the advantage that the control elements contained do not protrude beyond the contour of the control switch or the front of its housing, as a result of which sticking to the control elements and any associated incorrect operation can be effectively avoided.
  • the arrangement of the two control panels together in a recess also has the effect of advantageously enhancing their visual and / or haptic emphasis.
  • the housing has a constriction on its long sides.
  • the constriction is arranged in a particularly advantageous manner between the biconvex curves.
  • the constriction can be located in particular in the area between the first and second control panel or in the area of the first control panel and preferably at the level of an operating element of the first control panel provided for the "crane travel forward" function.
  • the constriction is then located between the two convex profiles seen from the outside in the area between the first and second control panels or in the area of the first control panel and in particular in the area of the control element for the "forward crane travel" function.
  • the first convex course of the long sides of the housing in the area of the first control panel seen from the outside therefore changes directly into the second convex course of the long sides of the housing in the area of the second control panel seen from the outside.
  • the two biconvex curves to each other in the region of the constriction preferably without a possible concave curve, merge directly and in this respect in particular in a kink-like manner.
  • the constriction thus resembles a striking notch, which leads to an advantageous enhancement of the visual and / or haptic highlighting of the individual control panels.
  • the housing has a first section, which can preferably include the third and at least partially also the first control panel, and a second section which adjoins the first section in the longitudinal direction and preferably the second Control panel can include.
  • the first section and the second section are angled so that they enclose an angle between them.
  • the two sections of the housing are angled around an imaginary axis running parallel to the transverse axis, so that its front side, preferably also its rear side, is curved in itself.
  • the first section of the housing opposite the upper end is always inclined with respect to a vertical direction even in the free-hanging state, which simplifies gripping the control switch.
  • control switch or its housing can be provided with a soft coating at least in some areas.
  • the coating serving as a soft coating is preferably produced by applying a multi-component lacquer to the housing.
  • the primary goal here is improved contact with the hand of a person operating the control switch, which hand encompasses the housing.
  • the at least one projection can be rounded off towards the long sides.
  • the rounding enables a transition from the projection into the long sides of the housing that is as seamless as possible, which further increases the ergonomics due to the absence of otherwise disruptive and / or unpleasant protruding corners of the projection.
  • the rounded design of the at least one projection also allows the control switch to be placed in a section of a finger, in particular the index finger, with the rounded projection.
  • the housing is naturally enlarged compared to the surrounding sections, which can be perceived as advantageous, in particular in the case of a large hand of a person operating the control switch. Even with this type of handling, the at least one protrusion provides exact haptic feedback regarding the correct position within the operator's hand.
  • the projections also serve to transmit tensile forces from the operator to the crane, which can be initiated via the control switch and the control line. In addition, the projections allow the operator to "hold" on the control switch and thereby carry the crane with him.
  • the housing can have two projections spaced apart from one another with respect to its longitudinal direction.
  • a first projection can be arranged at the level of an area that faces the third control panel and is located below two control elements of the first control panel that are arranged alongside one another along the transverse axis, while a second projection at the level of a lower area of the third that faces away from the first control panel Control panel is located.
  • the distance between the two projections can be selected such that the section of the housing located between the two projections is gripped by the ring and middle fingers of one hand, while the index finger is placed above the first projection.
