Publication number: 20040163325Abstract: A method and a system for emergency evacuation of building occupants and to a method for modernization of an existing building with the evacuation system. The system is used in a multi-story building having a plurality of floors and with at least one elevator positionable at selected landings of the floors. A first device is provided for measuring the number of persons in the building and a second device is provided for detecting an emergency condition in the building. At least one control unit is provided for determining or for estimating a number of building occupants in the building. The control unit defines at least one evacuation zone in the building during the emergency condition. Based on this information, the control unit defines at least one designated floor in the building during the emergency condition. Then the system evacuates the building occupants with the elevator car and/or a stairway from the evacuation zone to the designated floor.Type: ApplicationFiled: December 15, 2003Publication date: August 26, 2004Applicant: Inventio AGInventors: Lorenzo Parrini, Peter A.

Publication number: 20040128913Abstract: A door with a sliding door leaf has guides that are arranged in the region of an edge of the door leaf. The guides include a belt so aligned that it extends by the belt length thereof longitudinally of the guide surface for the door leaf in the direction of sliding of the door leaf. When the door leaf is sliding, the belt runs with the door leaf in such a manner that a portion of the belt bears against the guide surface when the door leaf is open, closed and sliding and thereby guides the door leaf.Type: ApplicationFiled: October 2, 2003Publication date: July 8, 2004Inventor: Peter Spiess

Patent number: 5869794Abstract: Method and device for stopping of an elevator cage due to a deviation of the elevator position, acceleration, or speed from a travel curve in excess of a certain predetermined safety margin. Travel parameters, computed by the elevator control, may be passed on to a drive control of a cage drive for moving and positioning of the elevator cage, and may also be passed on to a drive control of a reference drive for moving and positioning a trigger part. Accordingly, each of the elevator cage and the trigger part may be driven by individual discrete drivers, but, due to each driver receiving the same travel parameters, the elevator cage and the trigger part move in synchronization. The trigger part may be coupled to the elevator cage to be movable when the elevator cage deviates from the computed travel curve. When the deviation from the travel curve exceeds a predetermined safety margin, the trigger part may actuate a safety switch to stop the cage or reference drivers or to arrest movement of the elevator cage.Type: GrantFiled: November 7, 1996Date of Patent: February 9, 1999Assignee: Inventio AGInventor: Peter Spiess

Patent number: 5667039Abstract: A roller for use in a roller guide for sliding elevator doors may include a resilient element for effecting quieter elevator operation. The resilient element may form a roller body with a bowl shaped annular casing of sheet steel to run along a carrier section including a preferably greased rail running surface. The roller body may be dimensioned such that the spring effect of the resilient element is stressed only within the elastic range or limit of the sheet steel. To obtain optimum spring effect, a radius of the rail running surface may be slightly greater than a radius of the roller body. Also, the roller body may include an open side.Type: GrantFiled: May 5, 1995Date of Patent: September 16, 1997Assignee: Inventio AGInventor: Peter Spiess

Patent number: 5655626Abstract: A roller guide for use with sliding elevator doors may include elements for effecting quieter sliding door running by reducing noise associated with the rollers running along the roller guide. The roller guide may by formed by a convex running surface made from a hose-like covering of sheet metal producing a spring effect. The hose-like covering may be dimensioned to utilize the spring effect within an elastic range or limit of the sheet metal, with the optimum spring effect occurring when a radius of the rail running surface is slightly less than a radius of a running surface. An elastic material, to dampen running noise, may be inserted between the hose-like covering and a carrier section. The carrier section may also include spaces for clamping respective ends of the hose-like covering.Type: GrantFiled: May 5, 1995Date of Patent: August 12, 1997Assignee: Inventio AGInventor: Peter Spiess

Patent number: 5616895Abstract: A door safety circuit for monitoring of story doors in lift installations. The door safety circuit includes a transmitter that produces a non-electrical signal which is guided by a series of conductor portions. The non-electrical signal may be transmitted through a first conductor partial portion to a latching device of a first story door, depending upon the latched state of the first story door, the signal may be either transmitted to a second conductor partial portion, which may be included within the latching device, or no longer transmitted. If the signal is similarly transmitted through a plurality of conductor partial portions and serially connected story door latching devices, the circuit may indicate that each story door is properly latched. The circuit may also include a plurality of sensors coupled to a failure recognition circuit for monitoring each conductor partial portion.Type: GrantFiled: October 5, 1994Date of Patent: April 1, 1997Assignee: Inventio AGInventor: Peter Spiess

Patent number: 5575357Abstract: An entraining apparatus for the coupling, unlatching and entraining of elevator shaft doors includes an entraining parallelogram which is movable laterally and is actuated by a door drive on an elevator car. The entraining parallelogram has two vertically extending entraining members, one entraining member being fixedly connected to a slide member horizontally movable in a guide (9) and pushed into a neutral abutment setting by a compression spring during the elevator travel. An arresting parallelogram includes a movable coulisse and the fixed entraining member coupled to an upper link having a pawl lever with a pawl. Upon arrival at a stopping floor, the entraining apparatus is pushed by a pair of shaft door rollers into a centered position and the left shaft door roller moves the coulisse inwardly to engage the pawl between teeth of a comb on the slide member and arrest the entraining apparatus. During travel of the car, the compression spring pushes the entraining apparatus to the neutral position.Type: GrantFiled: April 13, 1995Date of Patent: November 19, 1996Assignee: Inventio AGInventor: Peter A.

Patent number: 5544720Abstract: An apparatus for entraining and unlatching an elevator car door and a shaft door includes an electromagnet having a movable armature attached to a first bellows mounted on a wall of the car. An entraining and unlatching cam is attached to a second bellows which is mounted on the car door. The cam has stiffened cam entry surfaces, cam surfaces and front surface. The bellows are connected by a hose as a closed pneumatic system operating with below atmospheric pressure. When the electromagnet is not actuated, an internal compression spring in the second bellows extends the cam into engagement with rollers mounted on a shaft door to splay the rollers thereby unlatching the shaft door and entraining it with the car door. At the same time, the first bellows retracts the armature to unlatch the car door. When the electromagnet is actuated, the armature latches the car door and the second bellows retracts the cam to permit the rollers to fold toward one another thereby latching the shaft door.Type: GrantFiled: January 26, 1995Date of Patent: August 13, 1996Assignee: Inventio AGInventor: Peter A.

Patent number: 4349759Abstract: A commutator for electrical machines and a method of manufacture of the commutator is disclosed which consists of a lamination assembly held together by a pair of shrink-rings. One of the rings serves to support the commutator on a commutator hub and comprises first and second ring portions having between them a decoupling portion. The first ring portion is in the form of a shrink-ring and holds together the lamination assembly. The second ring portion is secured to the commutator hub. The other shrink-ring also holds together the lamination assembly. In the method of manufacture of the commutator, both the first and second ring portions are simultaneously shrunk on to the lamination assembly and commutator hub respectively.Type: GrantFiled: December 9, 1977Date of Patent: September 14, 1982Assignee: BBC Brown, Boveri & Company, Ltd.Inventors: Niklaus Arnold, Josef Schmidli, Peter Spiess
