Retractable Stadium Roofs And Transport Mechanism Therefor

View page
US Patent:
6367206, Apr 9, 2002
Filed:
Jul 3, 2000
Appl. No.:
09/609727
Inventors:
Cyril J. Silberman - Minnetonka MN
M. David Sadinsky - Minneapolis MN
Barton L. Riberich - Brooklyn Park MN
Cheuk A. Cheng - New Brighton MN
Dick Eide - Minneapolis MN
Lennart Nielsen - Edina MN
Assignee:
Uni-Systems, Inc. - Minneapolis MN
International Classification:
E04B 716
US Classification:
52 66, 52 6, 52 64
Abstract:
A stadium that is adapted for open use during good weather as well as for covered use during poor weather includes a foundation and a pair of movable end roof members that are movable between first, retracted positions and second, operational positions for covering first and second end areas, respectively, of the stadium. The stadium also includes a center roof member that is movable between a retracted position and an operational position for covering a center area of the stadium. All of the roof members are supported for movement between the retracted positions and the operational positions by a guide and support assembly that includes at least one rail member that is secured to the foundation and a plurality of independently suspended follower assemblies that are mounted to the respective roof member. Each of said follower assemblies include a wheel member that is positioned in contact with the rail and a resilient member that is interposed between the wheel member and the roof member, so that each of the wheel members is independently suspended with respect to the other wheel members. This creates a number of advantages, including that it makes alignment easier to achieve and maintain, and that it allows the guide and support assembly to be constructed with a large number of small wheels and to have a relatively low profile, which makes the system attractive from both an aesthetic and a structural standpoint.

Transport Mechanism For Large Structures Such As Retractable Stadium Rooves

US Patent:
6415556, Jul 9, 2002
Filed:
Jul 3, 2000
Appl. No.:
09/609728
Inventors:
Cyril J. Silberman - Minnetonka MN
M. David Sadinsky - Minneapolis MN
Barton L. Riberich - Brooklyn Park MN
Cheuk A. Cheng - New Brigton MN

Lennart Nielsen - Edina MN

Assignee:
Uni-Systems, Inc. - Minneapolis MN
International Classification:
E04B 1346
US Classification:
52 66, 52 6, 52 64, 52 83
Abstract:
An edifice such as a sports stadium is adapted for open use during good weather as well as for covered use during poor weather by having at least one movable roof member. Each movable roof member includes a transport mechanism that is constructed and arranged to permit the roof member to move in a predetermined path with respect to the underlying structure of the edifice. The transport mechanism includes structure for supporting both ends of the roof member, which bridges an otherwise open area of the edifice. In order to permit some flexure and movement of the roof member with respect to the underlying edifice, as will inevitably occur as a result of natural forces such as winds, orientation structure is provided for maintaining the transport mechanism in a predetermined orientation while simultaneously permitting a limited amount of movement of the roof member in a direction that is nonparallel to the predetermined path of movement. The orientation structure has been found to be most effective when it is provided at but one end of the roof member.

US Patent:
7594360, Sep 29, 2009
Filed:
Mar 3, 2006
Appl. No.:
11/367564
Inventors:
Cyril Silberman - Minnetonka MN, US
Barton L. Riberich - Brooklyn Park MN, US
Lennart Nielsen - Edina MN, US
Michael Becker - New Hope MN, US
Alan Wilcox - Rogers MN, US
Timothy J. Kline - Minnetonka MN, US

Assignee:
Uni-Systems, LLC - Minneapolis MN
International Classification:
E04B 1/346
E04B 7/16
US Classification:
52 66, 52 6, 52 64
Abstract:
A movable roof member includes a transport mechanism that is constructed and arranged to permit the roof member to move in a predetermined path with respect to the underlying structure of the supporting edifice. The transport mechanism includes structure for supporting both ends of the roof member, which bridges an otherwise open area of the edifice. In order to permit some flexure and movement of the roof member with respect to the underlying edifice, as will inevitably occur as a result of natural forces such as winds, a lateral release system is provided for maintaining the transport mechanism in a predetermined orientation while simultaneously permitting a limited amount of movement of the roof member in a direction that is nonparallel to the predetermined path of movement. The lateral release system has been found to be most effective when it is provided at but one end of the roof member. The lateral release system preferably includes a linear slide bearing that in the preferred embodiment has a longitudinal axis that is oriented so as to be substantially perpendicular to the predetermined path of travel of the roof member.

Cable Drive And Control System For Movable Stadium Roof Panels

US Patent:
8186107, May 29, 2012
Filed:
Mar 3, 2006
Appl. No.:
11/367563
Inventors:
Cyril Silberman - Minnetonka MN, US
Barton L. Riberich - Brooklyn Park MN, US
Lennart Nielsen - Edina MN, US

Assignee:
Uni-Systems, LLC - Minneapolis MN
International Classification:
E04H 3/10
E04B 1/346
A63C 19/00
B65H 75/48
US Classification:
52 6, 52 66, 472 92, 2423906
Abstract:
A convertible stadium includes a playing field, a seating area, a stationary roof structure and a large, heavy roof panel mounted for movement with respect to the stationary roof structure, A plurality of cable drums are mounted for movement together with the roof panel. Each cable drum has at least one cable wound thereabout. The cable is secured to the stationary roof structure and is payable from the respective cable drum. The system is designed so as to minimize movement between the cable and the roof panel, so there will be no possibility of frictional engagement therebetween.

Kinetic Wall System And Method

US Patent:
20090223140, Sep 10, 2009
Filed:
Mar 4, 2008
Appl. No.:
12/041902
Inventors:
MICHAEL BECKER - NEW HOPE MN, US
PETER FERVOY - ST. PAUL MN, US
TIMOTHY J. KLINE - MINNETONKA MN, US
ALEXANDER KRUEGER - RICHFIELD MN, US
DAN KRZMARZICK - BLOOMINGTON MN, US
LENNART NIELSEN - EDINA MN, US
BARTON L. RIBERICH - BROOKLYN PARK MN, US
CYRIL SILBERMAN - MINNETONKA MN, US
Assignee:
UNI-SYSTEMS, LLC - MINNEAPOLIS MN
International Classification:
E04B 1/00
US Classification:
52 64, 527411
Abstract:
A retractable wall system for a structure such as a building includes a torque tube and a kinetic wall member that is secured to the torque tube. A shaft that is at least partially positioned within the torque tube is secured to the structure so that rotation with respect to the structure is precluded. A drive mechanism that is at least partially positioned within the torque tube is constructed and arranged to selectively change a rotational position of the shaft with respect to the torque tube so that the wall member may be moved with respect to the structure. An electronic control system may be provided for monitoring and controlling movement of the kinetic wall member with respect to the structure. The electronic control system may be integrated with other control systems of the structure, such as the electronic control system of the structure's HVAC system.
