摘要:
The invention relates to an elevator system for the transport of loads and/or persons in an elevator shaft with at least two elevator cars which can be moved in the elevator shaft and are connected to a counterweight via carrying means, wherein a drive is associated with each car. In order to develop the elevator system further in such a manner that it can be produced inexpensively and has an improved transport capacity it is suggested in accordance with the invention that at least one common track section and, in addition, separate track sections arranged next to one another be associated with at least two cars in sections along the elevator shaft, wherein the cars can be moved not only in the same direction but also in directions opposite to one another.

An elevator installation for conveying persons/goods, a method for operating the elevator installation and to a method for modernizing an elevator installation. The elevator installation includes at least two cages arranged one above the other in a vertical travel direction, and a drive per cage for moving the cages. The cage and the drive are connected by way of a conveying member. A counterweight for weight compensation of each cage. At least one cage guide rail is provided for guiding the cages, and at least a pair of counterweight guide rails are provided for guiding the counterweights. The drives are arranged near different first walls in the shaft.

An elevator apparatus comprises two (2) or more sets of elevators with one (1) piece of an elevating passage. Each of the elevators has an elevator car and a hoist, which is connected to the elevator car through a rope. Each the hoist has a sheave, a motor and a brake. The hoist of one of the elevators is projected above the elevator car of the other elevator. Also, open/close doors of the one elevator and those of the other elevator are disposed, so that they shift in front and behind. Door cases of the juxtaposing elevators are disposed to overlap with each other in front and behind.

A shaped section (10) for a shower partition door (S) is mounted in such a way that it can pivot about an eccentric vertical axis (A) and supports partial leaves (22, 24) in longitudinal grooves (12, 14) on both sides. Said partial leaves can be adjusted in relation to each other in at least two directions. Plane elements (30, 38) can lock into a shaped body (11) on the front and/or rear sides, for example a hollow section which accommodates pivot bearings (26, 28) at the end. The shaped section (10) can be raised and lowered between said pivot bearings even during the pivoting movement, as well as stopped in at least one door position. A mounting or supporting plate (50) can be adjusted and fixed beneath the lower pivot bearing (26) for alignment purposes. The weight of the door rests on a spring arrangement (F) which can be prestressed, above said mounting or supporting plate. A pressure spring (67) can be contracted and released using a manual adjusting device in order to lower or raise the door (S). A pulling piece (61) of a pulling device (60) acts on a cam (57) in such a way that said pulling device axially engages with a pulling head (64) on a spring abutment (65) in the shaped section (10), said spring abutment resting in a spring cup (66) which is longitudinally displaceable in a lower fixed sleeve (21) above the lower pivot bearing (26). An upper polygonal sleeve (68) can be twisted in relation to the fixed sleeve (21) in order to adjust the prestress of the pressure spring (67).

A display lifting device is provided which is mounted within a ceiling plenum and is arranged for concealing a support framework, lifting arm and display within the ceiling area. A support arm for the display is pivotally mounted within the framework and is biased in the downward position and supported by a cable mounted on a cable drum drivingly connected to a reversible motor. The support arm comprises at least two telescoping sections with the cable connected to the end of the inner lower most section so that as the cable is extended the arm pivots downward with the telescoping sections extending through gravity to their fullest extent. In this way, the display can extend a considerable distance from the ceiling for viewing by the audience while in the retracted position a very small opening and space within the plenum is required for concealment. Mechanical stops and limit switches are provided at both extremes of the movement of the display and support arm to restrict the angular movement of the arm. A cover matching the opening in the ceiling is attached to the support arm and is pivoted from the ceiling to close the ceiling opening when the arm is raised into the upper concealed position. Actuation of the display lifting device can be made with a wired control panel or a remote control device.

A media wall for supporting various types of media, such as plasma screen or flat screen television sets, as well as other types of thin media, includes an upright vertical wall to which the media is mounted. The wall may include a pair of sidewalls mounted to a back face of the vertical wall, as well as a shelf extending forwardly from the vertical wall. At least one aperture may be included for enabling power or data cables to be inserted through the wall from the front to the back. A video camera support may be mounted on the vertical wall. The wall may be pivotable about a vertical axis to allow easy access to the rear of the wall for setting up and adjusting the electrical cabling used to support the media.

An anti-theft device for securing an A.T.M. to a floor comprises a first beam which is secured to the floor by an overlapping beam. The beam sits in a recess in the beam, and is allowed limited free movement. The A.T.M. is secured to the beam. A plate, carrying a surrounding frame, lays between the beam and the A.T.M. The frame inhibits access to the securing plate.

A rack assembly for supporting electronic units which includes a generally rectangular frame having reinforcing plates welded thereto to extend outwardly therefrom, and a reinforced mounting portion disposed at the lower end of the frame and having a length corresponding generally to the height of the vertical spacing between a permanent floor and secondary flooring disposed above the permanent flooring so that the mounting portion can be secured directly to the permanent flooring and pass upwardly through an opening in the secondary flooring. A plurality of the rack assemblies may be arranged in side-by-side relationship in a room, and the reinforcing plates of adjacent rack assemblies provide wire management channels.

A fitting for walls or panels comprises a female coupling element which can be mounted on the panel or wall and a support element which can be fixed releasably in the female coupling element. Coupling means and complementary coupling means provided for restraining the support element in the female coupling element comprise a pin and a catch seat, respectively, and resilient means are also provided for urging the pin into the catch seat so as to prevent accidental disengagement of the coupling means and the complementary coupling means.
摘要:
An elevator system for traveling on a rail attached to the outside of a high-rise building. One elevator having a telescoping arm attached for reaching any position on or above the building. A platform or cabin attached to the telescoping arm can deliver materials to the building while under construction and thereafter be used for building maintenance such as window washing. The movable platform adjacent a building can take the place of scaffolding for a safer work environment. The telescoping arm may have various attachments for different functions such as for rescuing people trapped in a high-rise during a fire or for positioning fire fighters and hoses or fire fighting equipment next to a fire. The elevators may be raised and lowered by motors connected to cables or under their own power.
