A sill (1, 1) for a lift door is manufactured with a method that includes the steps of providing at least one support element (2) and an upper profile (4) that defines at least a boundary surface (6) of a first groove longitudinal (8) for slidingly receiving a lift door. The support element (2) and the upper profile (4) are joined, placing a first demarcation profile (10, 10) alongside the upper profile (4), so that a boundary surface (12) of the first demarcation profile delimits part of the first longitudinal groove (8). A sliding transversal cross-section of the first longitudinal groove (8) is adjusted by approaching/distancing the boundary surfaces (6, 12) and, having obtained a desired sliding transversal cross-section, constraining the mutual position of the first demarcation profile (10, 10) and of the upper profile (4).

Elevator systems are provided. The systems include an elevator car movable along an elevator shaft, the shaft having a pit floor and a shaft top, the elevator car having an elevator car door sill, a plurality of landings arranged along the elevator shaft, wherein each landing has a landing door, and a car apron assembly. The car apron assembly includes a semi-rigid curtain attached to the elevator car door sill at a first end of the semi-rigid curtain. The semi-rigid curtain folds from a deployed state to a folded state when contacting the pit floor, and, when in the deployed state, the semi-rigid curtain extends below the elevator car to block an open landing door that is lower than the elevator car when the elevator car is positioned offset and above an adjacent landing.

A seal member for sealing a gap between a car-side door sill and a landing-side door sill is slidable between a sealing position and a retracted position and is driven by a link mechanism. The seal member is connected to an actuation spring that receives a movement force toward the sealing position. The link mechanism releases engagement with the actuating member in synchronization with a start of a door open operation of the car door to permit sliding toward the sealing position caused by the actuation spring. The link mechanism is engaged with the actuating member of the car door side in synchronization with movement of the car door toward a door close end to move the seal member to the retracted position resisting to the actuation spring.

A cleaning system for cleaning a door sill of an elevator includes at least one nozzle mounted within the door sill. An outlet of the at least one nozzle directed into a sill cavity formed in the door sill. An air supply arranged in fluid communication with the at least one nozzle. Air from the air supply is selectively provided to the at least one nozzle to remove debris from sill cavity.

An illustrative example elevator sill assembly includes a sill plate and at least one support arm secured to the sill plate. A mounting bracket is configured to be mounted to an elevator car. The support arm is supported on the mounting bracket to allow the support arm to pivot relative to the mounting bracket. At least one actuator arm has a portion configured to be contacted by a door of the elevator car to cause movement of the actuator arm relative to the mounting bracket as the door moves into an open position. The movement of the actuator arm causes the support arm to pivot relative to the mounting bracket to thereby cause the sill plate to pivot from a stored position to an actuated position.

An illustrative example elevator sill assembly includes a sill plate and at least one support arm secured to the sill plate. A mounting bracket is configured to be mounted to an elevator car. The support arm is supported on the mounting bracket to allow the support arm to pivot relative to the mounting bracket. At least one linear actuator has a moving portion that moves in a vertical direction to cause the at least one support arm to pivot relative to the mounting bracket to thereby cause the sill plate to pivot from a stored position to an actuated position.

Sliding door systems are provided herein. The sliding door systems include a sliding door having a panel base, a sill having a guide channel having a stop arranged within the guide channel, wherein the guide channel includes a first subchannel and a second subchannel, wherein the first subchannel is defined at least partially by the stop and wherein the stop defines a gap connecting the first subchannel to the second subchannel, and an anti-derailment system. The anti-derailment system includes a first member having a first end and a second end, wherein the first end extends into the first subchannel and the second end connects to the panel base and a second member attached to the first member, wherein the second member is positioned within the second subchannel of the guide channel.

A lower guide assembly for an elevator landing door system, including: a landing door plate; an anti-off component; and a sill component that includes: a base; and a first support and a second support that are detachably mounted on the base. The first support, the second support and the base form a guide slot that extends along a translating direction of the landing door plate, the width of a space of the guide slot that is used to accommodate the body of the anti-off component is less than the width of the head of the anti-off component, the base is provided with a first protrusion that extends toward the first support at an outer side near the first support, and the first support is provided with a recess used to accommodate the first protrusion.

A trench drain includes a trench, a grating seat and a grating hingedly connected to the trench. The trench has a base wall with peripheral side walls extending upwardly therefrom and an outwardly-extending peripheral flange. The grating seat is configured to receive the grating. The peripheral side walls of the trench have a pair of opposing elongated slots formed therein and the grating has a pair of posts on opposing ends thereof. Each of the pair of posts on the grating are received in a respective one of the pair of opposing elongated slots of the trench to establish an axis of rotation.

Car door (1) comprising: two sliding door panels (2, 3); two profiles (6, 7), each of which is arranged below one of the two door panels (2, 3), the profiles (6, 7) being partially counter-shaped so as to slide with respect to one another therefore while the door (1) is opening they move towards one another to compose a sill (5).
