The invention concerns an elevator having a car with a roof and a barrier arranged on at least one side of the roof to provide anti-fall safety protection.
Elevators feature cars, which, via means of support, for example in the form of supporting cables, or supporting belts, can be moved up and down in an elevator shaft by means of a drive unit. For particular situations such as, for example, maintenance tasks or inspections, it is necessary for persons to spend time on the elevator car roof. If the width of a gap between the car and the adjacent shaft wall is too large, barriers must be installed on the car roof to provide anti-fall safety protection.
As a general rule various items of electrical or electromechanical equipment and installations necessary for operation of the elevator system are arranged on or in the elevator car. These items of equipment and installations, hereinafter referred to as the “car electrical system”, include, for example, the door controller, equipment for the evaluation of shaft information and for door monitoring, equipment for operating the system during maintenance, communications equipment, energy storage devices, car lighting or air conditioning systems. The car electrical system is supplied with power by way of cables, and at least elements of the car electrical system can communicate with one another by means of cables. Such cables are also located in the region of the car roof. In practice, the cables are often arranged on the car roof in a more or less exposed manner. The result is a disadvantageous organization of the cables and a safety risk in the form of “trip hazards” for the service personnel on the car roof. In principle, the cables could also be routed in a kind of double floor underneath the car roof, but this would be expensive and complex.
It is therefore an object of the present invention to avoid the known disadvantages, and in particular to provide an elevator in which cables of the car electrical system can be arranged simply and in a space-saving manner on the car roof. In particular, the cables should not represent a risk for any persons located on the car roof.
The said objects are achieved with an elevator having a barrier to provide anti-fall safety protection arranged on at least one side of the roof of the car. The barrier has at least one bar, in particular a handrail formed from a bar and a toeboard, formed from a bar, which is fixed on an upper side of the car roof and arranged underneath the handrail. An additional intermediate bar can, if required, be arranged underneath the handrail as a third rail, preferably at mid height. By virtue of the fact that at least some of the cables of the car electrical system are or can be routed within at least one of the bars, the said cables can be organized simply and in a space-saving manner on the car roof. Any unintended encroachment on the cables, or possibly even stumbling over the cables can be ruled out for practical purposes. Since no complex additional measures are required the inventive solution also has advantages in terms of cost.
The bar, such as, for example, the toeboard, can feature a hollow profile forming a cavity for purposes of accommodating the cables. Alternatively the bar can feature an open, trough-shaped profile, which together with an upper side of the car roof forms a cavity for purposes of accommodating the cables. The trough-shaped profile can be configured as one part, or as multiple parts. The hollow profile could, for example, be a round tube. For the installation on the roof it can, however, be advantageous if the hollow profile is a rectangular profile. The trough-shaped profile can also have a rectangular shape. Needless to say, however, other shapes for the trough-shaped profile, or for the hollow profile, would also be conceivable. The arrangement is simple to manipulate and simple to assemble and disassemble.
For the housing of a plurality of cables it can be advantageous if the hollow profile or the trough-shaped profile is at least 8 cm high, and preferably is at least 10 cm high. In this manner a sufficiently large cavity ensues for purposes of accommodating the cables. The high toeboards can also serve as a stop for shoes and a kick plate for persons on the car roof. The hollow profile or the trough-shaped profile can, for example, consist of a metallic material. Needless to say, however, it would also be conceivable in principle to produce the toeboard from a plastic or another material.
It can be advantageous if the trough-shaped profile has at least one sidewall projecting from the car roof and an attachment section adjoining the sidewall, wherein the attachment section lies flat, or can lie flat, on the car roof. Particularly preferably the trough-shaped profile has sidewalls projecting at right angles from the car roof, wherein an attachment section adjoins each sidewall. Such a trough-shaped profile can thus be a top hat-profile or an omega-profile.
Furthermore it can be advantageous if the bar is constructed from at least two profiled parts that can be assembled together. Such a bar in at least two parts enables a simple introduction or removal into or out of the bar.
If the cable-routing bar is a toeboard, the toeboard can feature detent means, which prevent encroachment on the toeboard. In addition to the increase in safety, by virtue of the detent means it is possible to prevent the toeboard from being deformed or even destroyed as a result of encroachment.
The toeboard can, for example, comprise a freestanding detent section directed away from the car floor as the detent means. The detent section can be a vertical section on a sidewall of the trough-shaped profile, or adjoining the hollow profile.
Further individual features and advantages of the invention ensue from the following description of examples of embodiment and from the figures. Here:
