Abstract

The door sill unit includes a bottom support, a support construction extending upwards from the bottom support and a support member being supported by a pivot on the support construction so that the support member can be rotated around the pivot between a first position and a second position.

First claim

The invention claimed is:

1. A door sill unit for an elevator landing door unit, the door sill unit comprising:
a bottom support extending into an elevator shaft and comprising a regulator positioned within the elevator shaft;
a support construction extending upwards from the bottom support;
a support member being supported with a pivot on the support construction so that the support member is rotatable around the pivot between a first position and a second position, the entire pivot being disposed above the bottom support; and
a temporary sill;
wherein the support member is made of a sheet that is bent so that a first branch and a second branch of the sheet are perpendicular to each other,
wherein the first branch is attached to the pivot,
wherein in the first position, the first branch extends in a vertical direction and the second branch extends in a horizontal direction, and
wherein in the second position, the first branch forms a support surface and extends in the horizontal direction into the elevator shaft, the second branch is located entirely within the elevator shaft and extends vertically downwardly below a floor of a landing, and the temporary sill is attached to the first branch of the support member and is configured to be attached to a guide of a door panel.

2. The door sill unit according to claim 1 , wherein the regulator comprises at least one bolt attached to the bottom support, an upper end of the at least one bolt attached to the support member, and the height of the support member being regulated by raising or lowering the at least one bolt in relation to the bottom support.

3. The door sill unit according to claim 1 , wherein the door sill unit further comprises a fastener configured to fasten the door sill unit from the bottom support to a floor of the landing.

4. An arrangement in an elevator, said elevator comprising a car, a lifting machinery and a shaft, said lifting machinery moving the car in a first direction upwards and downwards in the vertically extending shaft between landings in a building, each landing being provided with an elevator landing door unit positioned in the opening between the landing and the shaft, said elevator landing door unit comprising a frame and at least one door panel, said at least one door panel opening and closing a passage between the landing and the car in order for passengers or goods to enter the car or leave the car at the landing, wherein the arrangement further comprises the door sill unit according to claim 1 for supporting the elevator landing door unit.

5. The door sill unit according to claim 2 , wherein the door sill unit further comprises a fastener configured to fasten the door sill unit from the bottom support to a floor of the landing.

6. The door sill unit according to claim 1 , wherein in the second position, a measurement member is positioned in a groove of the temporary sill, and an edge of the measurement member extends to a vertically extending plum line provided in the elevator shaft and the measurement member is configured to determine the correct position of the door sill unit with respect to a landing.

7. The door sill unit according to claim 1 , wherein in the first position, the bottom support is located within an interior portion of the support member.

8. A method for installing an elevator landing door unit comprising a frame and at least one door panel into an opening between a landing and an elevator shaft, said method comprising the steps of:
attaching a door sill unit at a landing at the opening between the landing and the elevator shaft, said door sill unit comprising a bottom support extending into the elevator shaft and comprising a regulator positioned within the elevator shaft, a support construction extending upwards from the bottom support and a support member supported with a pivot on the support construction so that the support member can be rotated around the pivot between a first position and a second position, wherein the support member is made of a sheet that is bent so that a first branch and a second branch of the sheet are perpendicular to each other, wherein the first branch is attached to the pivot, wherein in the first position, the first branch extends in a vertical direction and the second branch extends in a horizontal direction, and wherein in the second position, the first branch forms a support surface and extends in the horizontal direction into the elevator shaft, the second branch is located entirely within the elevator shaft and extends vertically downwardly below a floor of a landing,
attaching a temporary sill on the support member and rotating the support member around the pivot into the second position so that a groove in the temporary sill opens horizontally to the landing,
positioning the elevator landing door unit in a horizontal position and attaching the elevator landing door unit from a bottom of the frame to the support member so that guide means at a bottom of the at least one door panel sets into the groove in the temporary sill,
rotating the elevator landing door unit with the support member around the pivot into the first position so that the elevator landing door unit is in a vertical position, and
attaching the elevator landing door unit from the frame to the walls of the landing.
