Abstract: An elevator car defining an interior space for accommodating passengers and/or cargo, comprising a support frame positioned above the interior space, a working platform moveable between a stowed position, above the interior space, and an operational position, within the interior space and at least one extendable suspension arrangement arranged to suspend the working platform from the support frame. The extendable suspension arrangement includes a connection plate, a first arm member connected at a first end to the support frame and slidably connected to a first connection point of the connection plate and a second arm member connected at another first end to the working platform and slidably connected to a second connection point of the connection plate.

Abstract: The instant invention provides a secure holding spacer unit to be used when assembling permanent stay-in-place formworks, also known as “permanent stay-in-place molds”, which are commonly used for the construction of concrete structures by putting together two boards or panels held together by a series of holding spacer units that are securely attached or hold to the surfaces of the cement panels by fastening means that pass through the width of the panels. The holding spacer units are selectively distributed within the internal cavity of the formwork and are attached to the panels, and are designed so that the panels remain permanently attached to the units of the spacers, to restrict the outward movement of said panels when pouring the concrete mix in the unit, which results in a permanent formwork with smooth exterior surfaces.

Abstract: An elevator car (6) defining an interior space (12) for accommodating passengers comprises a support frame (22) positioned on a top side of the interior space (12); a support structure (30) pivotably mounted to the support frame (22); and a working platform (28) pivotably mounted to the support structure (30). The support structure (30) is pivotable with respect to the support frame (22) and the working platform (28) is pivotable with respect to the support structure (30) between a retracted position, in which the working platform (28) and the support structure (30) are oriented close to the support frame (22), and a deployed position, in which the support structure (30) extends away from the support frame (22) towards the interior space (12) and the working platform (28) extends away from the support structure (30).

Abstract: A blocking device (2) for blocking access to an door unlocking device (118) of an elevator system (102) comprises: an outer element (4), which is introducible into an access opening (30) providing access to the door unlocking device (118); and an inner element (6), which is introducible into the outer element (4). The inner element (6) is configured for bringing the blocking device (2) into a fixing configuration, in which the outer element (4) is fixedly engaged with the access opening (30), by introducing the inner element (6) into the outer element (4).

Abstract: An elevator car (6) defining an interior space (12) for accommodating passengers and/or cargo comprises a support frame (22) positioned on top of the interior space (12); and a working platform (28) movably mounted to the support frame (22) by a support structure (31). The support structure (31) comprises at least one scissor mechanism (30) including two scissor legs (30a, 30b) pivotably connected with each other. A first end of each scissor leg (30a, 30b) is pivotably connected to the support frame (22), and a second end of each scissor leg (30a, 30b) is pivotably connected to the working platform (28). The support structure (31) further comprises at least one gas spring element (32) extending between the scissor legs (30a, 30b) of the at least one scissor mechanism (30). The at least one gas spring element (32) may be configured for supporting the movement of the working platform (28).

Abstract: Embodiments are directed to obtaining an elevator with low overhead space and low pit space by positioning a car of the elevator to have a space from a vertical wall of a hoist-way, mounting a governor in the space between the car and the wall, and mounting a sheave to the car, wherein the sheave is positioned in a projection of the car to the wall.
