Abstract
A lift system for a panel, provided with a chain, a drive and a housing, wherein the housing is arranged to attach the system to a frame, wall and/or ceiling, wherein, near an end, the chain is arranged to attach a panel, wherein the drive is arranged to retract at least the end of the chain into the housing and to release it from the housing for storing and releasing the panel, respectively, wherein at least a number of successive links of the chain are pivotable relative to one another as far as a stop under the influence of gravity, so that, in use, back parts of the links, of at least a released part of the chain, form an arc.
Claims22
A lift system for a panel comprising:
- a chain having a distal end arranged to attach a panel;
- a drive operatively associated with the chain;
- a housing being configured to attach the system to a frame, wall and/or ceiling;
- the drive being constructed and arranged to retract at least the distal end of the chain into the housing and to release it from the housing for storing and releasing a panel attached to the chain, respectively;
- and
- at least a number of successive links of the chain being pivotable relative to one another as far as a stop under the influence of gravity, so that, in use, back parts of the links, of at least a released part of the chain, form an arc.
(canceled)
The method for releasing and retracting a panel from and into a housing, respectively, wherein a panel is attached near a distal end of a chain, wherein the panel and at least a part of the chain are released, wherein at least a number of successive links of the released part of the chain pivot relative to one another as far as a stop under the influence of gravity so that back parts of the respective links form an arc.
