Description

The The invention relates to a car door apron for an elevator car or for a car of a lift.

Remains an elevator car between two building floors due to interference stand, so the standard requirements according to the clear distance between the floor of the elevator car and the associated lower one Building floor as far as possible be covered. To meet this standard requirement, cabin door aprons are known, the from the car door sill protrude down.

is the respective cabin door apron as fixed cabin door apron with a corresponding height dimension dimensioned to meet the said standard, so is especially at an elevator system with a shortened pit the problem exists that the cabin door apron a Liberation trip to the lowest building floor, under which the shortened Chess pit is located, does not allow without causing damage the cabin door apron comes.

From the FR 2 841 886 A1 a cabin door apron is known which has a projecting from the car door sill downward housing with a front wall and two side walls and which is open on the underside. In the housing two apron surface elements are provided which in the active position with the housing and connected to each other telescopically. the lower side opening of the housing protrude downwards.

flap elements to close the lower-side housing opening not in this known cabin door apron intended. Also a back wall shows the case this known cabin door apron not on.

Of the Invention has for its object to provide a cabin door apron, which also works well for lifts with a shortened pit suitable.

These The object is achieved by the Features of claim 1, i. by a cabin door apron with one from the car door sill downwardly projecting housing, a front wall, a back wall and has two side walls, and which is open on the underside, wherein at the lower-side opening of the housing two flap elements are attached, each one to an associated, in the underside corner portion of the housing provided axis between a closed position and an open active position and can be pivoted forth, and in the housing at least two apron area elements are provided in the open Active position of the two flap elements connected to each other, telescopically from the bottom opening of the housing sticking out, solved.

In the closure position of the two flap elements are at least two apron elements in the from the car door threshold after bottom housing accommodated space or space, so that the housing with relatively small height dimensions can be dimensioned without thereby affecting the effectiveness of Kabinürschürze invention would be limited, because the cabin door apron in the open active position the two flap elements in their height dimension around the height dimensions the at least two apron area elements is enlarged. With the cabin door apron invention are so clear openings between the ground due to a fault in an elevator shaft stuck elevator car and the thereof floor space spaced bridged such that the relevant ones Standard requirements met easily can be.

The Axes of the two flap elements extend between the front and the rear wall of the housing to the side walls preferably in parallel.

to defined space- or space-saving storage of at least two Apron surface elements in the case in the closed position of the two flap elements and for trouble-free telescopic extension of the at least two skirt surface elements out of the case in the open Active position of the two flap elements, it has to be advantageous proved when the two housing side walls inside first guide elements for the Apron surface elements and when the two flap elements on the inside second guide elements for the Apron surface elements have, with the first guide elements in the open Active position of the two flap elements are aligned. The first and second guide elements serve to the skirt surface elements in the open Active position with their side edges tilt-free, well movable lead to the desired telescopic renewal to effect the cabin door apron.

A structurally simple training is characterized in the cabin door apron invention achieved that the apron area elements in the open Active position of the two flap elements extended telescopically Condition are interlocked with each other.

As it is advantageous in the invention proper cabin door apron, when the housing has at least one operable by a flap element switch. It is preferred if the housing has a pair of switches which can be actuated by means of the two flap elements. These switches are used to prevent damage to the telescopically extended cabin door apron, ie the apron surface elements telescopically protruding out of the housing in the open active position of the two flap elements in the lowermost building level position of the elevator car in an elevator installation with a shortened shaft pit.

Further Details will be apparent from the following description of a in the drawing illustrated embodiment of the cabin door apron invention.

10 a section along the section line XX in 3 , and

11 the detail XI according to 10 on a larger scale.

The figures show an embodiment of the cabin door apron 10 with one of a car door sill 12 downwardly projecting housing 14 , The housing 14 has a rear wall facing an elevator shaft 16 on, from the two opposite side walls 18 stand in the same direction. On the side walls 18 is a front wall 20 of the housing 14 attached. The housing 14 is underside with an opening 22 educated. At the bottom opening 22 of the cuboid housing 14 are two flap elements 24 attached, each around an associated, in the lower corner area 26 of the housing 14 provided axis 28 between an in 1 drawn closure position and one in 2 drawn open active position can be pivoted back and forth.

In the embodiment of the cabin door apron shown in the figures 10 are in the case 14 two apron elements 30 and 32 intended. Like from the 6 and 7 is seen, the apron elements 30 and 32 in the inactive closed position of the two flap elements 24 in the case 14 the cabin door apron 10 accommodated space or space saving. In the in the 2 and 8th illustrated open active position of the two flap elements 24 are the two apron elements 30 and 32 connected together and protrude from the bottom opening 22 of the cuboid housing 14 down out.

So that the two apron area elements 30 and 32 after opening the flap elements 24 around their axes 28 easily caused by gravity from the housing 14 move out telescopically, have the two housing side walls 18 inside first guide elements 34 for the apron area elements 30 and 32 and the two flap elements 24 inside second guide elements 36 for the apron area elements 30 and 32 on that with the first guide elements 34 in the open active position of the two flap elements 24 to curse like that 8th clarified. The 8th also shows that the two apron elements 30 and 32 in the open active position of the two flap elements 24 in the telescopically extended state with each other by a hook and a barb 38 . 40 interlocked with each other. The apron area element 30 is with a hook 42 with a barb 44 in the open active position of the two flap elements 24 hooked.

The housing 14 has a pair of switches 46 on, by means of the two flap elements 24 are operable. Are the two flap elements 24 in the closed position, so allow the switches 46 a ride with the cabin door apron 10 equipped elevator car even with an elevator system with a shortened pit to the lowest building floor. Are the two flap elements 24 However, pivoted from the closed position to the open active position, so are the switches 46 in such an operating or switching state that a ride of the elevator car in an elevator system with a shortened pit in the lowest floor or a liberation drive only at inspection speed is possible. When the apron elements 30 and 32 in the case 14 reset and the flap elements 24 have been swung back into the closed position, the elevator system can return to normal operation.
