Switch arrangement for a lift, in particular a personnel lift and/or a goods lift
A switch arrangement for a lift, preferably a personnel lift or goods lift, including marked pushbuttons and an electrical conductor connection to a control device of the lift. The switch arrangement is provided with at least one elastically deformable plate element with the pushbuttons with the marking on the upper side of the button. A recognition element for the bending in the button is arranged beneath this plate element of the at least one pushbutton. In addition, an electrical conductor connection is provided from the recognition elements to the control device. As a result, it is possible for thinner and more user-friendly switch arrangements to be installed in or outside a lift, in particular for controlling it, or for general functions.
1 . Switch arrangement for a lift, comprising:
at least one elastically deformable plate element,
at least one pushbutton contained in the at least one elastically deformable plate element,
at least one recognition element beneath the at least one elastically deformable plate element and configured to detect bending of the at least one pushbutton,
an expansion measurement strip assigned to each of the least one recognition element and configured to provide a measure of the bending of the at least one pushbutton,
at least one electrical conductor connection connecting the at least one recognition element to a control device of the lift,
wherein the switch arrangement is integrated for its operation in at least one handrail in or next to the lift, and the at least one electrical conductor connection is conveyed from the handrail to the control device of the lift,
wherein the handrail is configured to enable a user to hold it or be guided by it.
2 . Switch arrangement according to claim 1 , wherein the at least one pushbutton, the at least one plate element and the at least one recognition element are provided with a thin overall layer thickness dimensioned in a millimeter range.
3 . Switch arrangement according to claim 1 , wherein the handrail is provided with a circular, angular, or other form of cross-section.
4 . Switch arrangement according to claim 1 , wherein a module is formed with the at least one elastically deformable plate element with the at least one pushbutton, with an identification of the at least one pushbutton on an upper side, the at least one recognition element, and the electrical conductor connection.
5 . Switch arrangement according to claim 4 , wherein the at least one pushbutton comprises a plurality of pushbuttons and the at least one elastically deformable plate element consists of a single plate element, the plurality of pushbuttons being formed in the module by the single plate element without gaps at their circumferences, and without any projections for damage caused by misuse.
6 . Switch arrangement according to claim 1 , further comprising a mechanical coupling piece arranged for bridging a distance between each of the at least one elastically deformable plate element and a respective one of the at least one pushbutton and the at least one recognition element, by means of which, when the at least one pushbutton is pressed, a transfer takes place of the bending of the at least one pushbutton via this coupling piece onto the at least one recognition element.
7 . Switch arrangement according to claim 1 , wherein a corresponding evaluation unit is assigned to the at least one recognition element, which is connectable by the at least one electrical conductor connection to the control device.
8 . Switch arrangement according to claim 1 , wherein each of the at least one pushbutton is provided with identification by means of at least one number, a character, and/or a letter in order to display a desired story of the lift, an alarm button, opening and closing buttons for a door of the lift, an outside call button, and/or buttons for other functions.
9 . Switch arrangement according to claim 1 , wherein the at least one recognition element of the at least one pushbutton, connected by lines to the control device of the lift, is provided with a power supply at a voltage of 3V to 24V.
10 . Switch arrangement according to claim 1 , wherein each of the at least pushbutton defines an effective button delimited by a peripheral line at its outer circumference, by another color, by a different material than outside the at least pushbutton and/or another identifier of the button at least pushbutton which is to be touched.
11 . Switch arrangement according to claim 1 , wherein the at least one pushbutton is installed in or at a specific part of the lift in a sealed manner.
12 . Switch arrangement according to claim 1 , wherein the at least one pushbutton comprises a plurality of pushbuttons.
13 . Switch arrangement according to claim 12 , wherein the at least one recognition element comprises a single recognition element configured to detect bending of all of the plurality of pushbuttons.
14 . Switch arrangement according to claim 1 , wherein the handrail has a rectangular cross-section.
15 . Switch arrangement according to claim 1 , wherein the handrail has a circular cross-section.
16 . Switch arrangement according to claim 1 , further comprising at least one transverse strip that secures the handrail to a wall of a cabin of the lift.
17 . Switch arrangement according to claim 16 , wherein the electrical conductor connection is guided through the at least one transverse strip.
18 . Switch arrangement according to claim 1 , further comprising means for securing the handrail to a wall of a cabin of the lift.
19 . Switch arrangement according to claim 1 , further comprising a detachable cover on an underside of the handrail.
20 . Switch arrangement according to claim 19 , wherein the detachable cover is spaced from the at least one recognition element.
