A door arrangement for a wind turbine includes a door with an outer side and an inner side and a door locking device for locking and unlocking the closed door by coupling and decoupling the closed door with a stationary component of the door arrangement of the wind turbine, wherein the door locking device includes a central component, an attachment and a connector, wherein the central component is attached to the stationary component by the attachment and connectable and disconnectable with the door by the connector for locking and unlocking the door by a person being at the outer side, wherein the attachment is manually releasable by a person being at the inner side for disconnecting the central component from the stationary component to unlock the door without tools.

A door holder, includes a retainer housing (230), which can be connected either to a door or a door frame, and a door retainer rod, which penetrates the retainer housing (230) and which can be articulated to the other of the door and the door frame The door retainer rod has at least one braking surface, and at least one braking element (50) that can be displaced toward the at least one braking surface is arranged on the retainer housing (230), which the braking element can be brought in contact with the at least one braking surface of the door retainer rod at least in some sections and thus produces a primary braking force component against the displacement of the door retainer rod, wherein the door retainer rod has at least one guiding surface, which is inclined with respect to the braking surface. A door holder that provides high holding forces at least in some sections is created in that at least one guiding element (235a, 235b) is arranged on the retainer housing (230), which the guiding element can be brought in contact with the at least one guiding surface at least in some regions and produces a secondary braking force component against the displacement of the door retainer rod.

An adjustable stop limits sliding sash window/door travel between a closed position and a safe position, where the safe position is a position less than a full-open position. The stop can be installed upon window/door master frames during initial manufacturing, or as an after-market option while the sash windows/doors are in service in a building. The safety stop may be comprised of a housing and a tumbler being pivotally mounted within a cavity in the housing, with a spring to bias the tumbler out of an opening in the housing. Mounting is by a flange extending from the housing, with spacers of varying thickness that are capable of removably attaching thereon to accommodate sash to master frame height differences. A safety member may be added to either the tumbler or housing to create a double action stop, requiring disengagement of the safety member, prior to toggling of the stop.

A door stop comprises an elongate threaded member having a flat head section, such as a flat head bolt or elevator bolt, and a mounting panel carried on the threaded member. A cushioning member made of felt or other soft non-abrasive material can be positioned on the head section. A locking nut can be threaded on the threaded member, with the mounting panel between the locking nut and the head section. An alternative door stop comprises a spring-loaded member, and an elongate rod telescopically positioned within the spring-loaded member and adapted for sliding movement therein. A mounting panel can be formed on the spring-loaded member. A head section can be positioned on one end of the rod, and a cushioning member, made of felt or other soft, non-abrasive material can be attached to the outer surface of the head section.

A telescoping door security bar for preventing intruders from entering a room. The telescoping door security bar uses a bolt and cotter pin, which are inserted completely through the door security bar to make it more stable.

A latch and method for a double sash tilt window includes a locking mechanism and a rack having proximal and distal ends. The proximal end of the rack is connected to the locking mechanism while the distal end of the rack is affixed to a slide bolt. The latch also includes a cam and a gear, the cam positioned on the gear and the gear enmeshed with the rack so that rotating the gear operates the slide bolt which prevents the window from tilting.

A portable door securement device is provided having a member extending from a first end engaged to a doorknob of a swinging door or endwall of a sliding door. A second end of the securement device is configured to be engaged with a support surface adjacent the door, to prevent opening of the door in a direction toward the engaged member.

A door locking device has a body with an overhanging ledge to mate with a bottom edge of a door. The body has a sliding member that is captured to the body and an eccentric cam with a faceted perimeter surface that rotates about an eccentric axis. When the eccentric cam rotates, the sliding member is moved from a retracted position toward an extended position. The sliding member has a foot portion that contacts a portion of the floor to lock the door by applying pressure between the floor and the bottom edge of the door. An arm is affixed to the eccentric cam and has a folding handle.
