Abstract: The present latch apparatus includes a swinging piece having first and second independent latches or sliders sliding in first and second slots. The first and second sliders slide independently of each other. The first and second sliders engage an undersurface of an extension of a first object such as a gate. If either the first or second slider is engaged on the undersurface, the swinging piece is locked and is not swingable such that the first object such as the gate cannot itself swing away from a second object such as a barrier section. Only when each of the first and second sliders has been slid beyond the undersurface can the swinging piece swing to permit the first object such as the gate to be released and thus swingable itself relative to the second object such as the barrier section.

Abstract: A privacy screen apparatus can include an upper member having a first end and a second end, at least one first leg connected to the first end of the upper member, at least one second leg connected to the second end of the upper member, and a bendable body connected to the upper member adjacent to a first edge of the body and adjacent to a second edge of the body to define a pouch or channel below the upper member. Cords, cables, or wiring can be positioned in the pouch or channel. The bendable body may also hang from the upper member to provide a visible barrier to provide privacy.

Abstract: In one aspect, a roller shade assembly for an architectural opening may generally include a first roller, a second roller and a looped shade extending around the first and second rollers. The looped shade may include at least one outer shade web forming a continuous loop around the rollers. In addition, the roller shade assembly may include an inner shade web configured to be wrapped around the first roller or the second roller such that the inner shade web is positioned within the continuous loop. The inner shade web may be coupled to the outer shade web(s) at a location along an inner perimeter of the continuous loop. Additionally, rotation of the first roller and/or the second roller in an unwinding direction may result in the inner shade web being unwound from the first roller or the second roller along the inner perimeter of the continuous loop.

Abstract: A door opening/closing control device includes: a driving part driving an actuator opening or closing a door; an operation switch operated for instructing opening/closing or stopping of the door; a first controller controlling driving of the actuator via the driving part in accordance with the operation; a manual opening/closing detector detecting that the door is manually opened or closed; and a second controller controlling the driving of the actuator via the driving part to assist a manual operation of opening or closing the door when the manual opening/closing detector detects the manual opening/closing operation. Then, when the second controller controls the driving of the actuator to assist the manual operation of opening or closing the door, even when the operation switch is operated, the first controller does not control the driving of the actuator in accordance with the operation, and the second controller continues to control the driving.

Abstract: On large window and door openings frequently made today, the manufacturers of venetian blinds in particular cannot cover the whole opening with just one blind. Therefore, it is necessary to arrange two or more hangings. However, these must be guided on both sides, and therefore a lateral guide between the two jambs of the opening is necessary. Such a guide is, however, undesirable for aesthetic reasons. According to the invention a temporary guide is created for the edges which need not be guided in the jambs and does this by means of a guide arrangement which can be accommodated rolled-up above the elevating device and can be introduced into the door or window opening.

Abstract: A device may limit opening of a sash hingedly coupled to a master frame, and includes: a bracket attached to the sash; a first arm having a first end pivotally coupled to the bracket; a second arm having a first end pivotally coupled to the first arm's second end; means for biasing the second arm into a retracted position; and a release assembly. The release assembly is secured to the master frame and includes a hook pivotable between a first position and a second position, which, in the first position, may be releasably received in an opening in the second end of the second arm when the second arm is in the retracted position, as the sash is closed and received within the master window frame The second arm is disengaged from the hook, permitting full opening of the sash, when the hook is pivoted into the second position.

Abstract: An architectural covering is presented that can be manually moved as well as moved through motorized manipulation. The system includes a header, a bottom bar and shade material and suspension cords extending therebetween. The header has an open interior compartment which includes a spring housing, a drive shaft assembly, spool assemblies and a motor assembly. The architectural covering can be manually moved by pulling on the shade material. The shade can also me moved via motorization by actuating the motor assembly through tugging, a remote control device, a voice actuation device or through the internet. In this way a novel architectural covering is presented that is easier to use than the prior art and has a plurality of methods of operation.

Abstract: A safety device for use in a fall arrest or fall safety system includes an energy absorber to absorb energy in the event of a fall or other impulse event. The energy absorber is a resilient element (such as a tolerance ring) providing an interference fit between a first component of the device and a second component of the device. In the event of a fall arrestor other impulse event, the first and second components effect movement relative to one another, the interference fit being overcome, and the resilient element/tolerance ring acting to resist the relative movement thereby absorbing energy.

Abstract: A multi-purpose ladder with improved rungs has two ladder sections, and each of the ladder sections comprises two inner rails attached with inner rungs and two outer rails attached with outer rungs. Each of the inner rungs is composed of an upper rung member, a square pipe shaped intermediate rung member, and a lower rung member. The upper rung member and the lower rung member each have a slant pedal section and two support sections. The two support sections join the upper and lower side of the intermediate rung member and the slant pedal section. The slant pedal section inclines an angle corresponding to the outer rungs such that the inner rungs provide strong strength for being stepped on.

Abstract: Corner structure of a hollow chamber seal includes a filler piece which is situated in a corner area of the hollow chamber seal. Filler piece supports the hollow chamber seal, with deformation, and diverts supporting forces into a component on which the hollow chamber seal is situated. Corner structure reliably prevents deformation of the hollow chamber seal, even after extended use, is easy to manufacture, and is aesthetic. Filler piece has a base which is adjoined by a T-shaped head made of an elastomeric material, and the head of the filler piece when installed protrudes into the hollow chamber seal through a slit which is introduced into the hollow chamber seal, and is supported on a wall of the hollow chamber seal oppositely situated from the component, with deformation. Base is supported on the component and diverts the supporting forces on the head into the component.

Abstract: A motorized window blind includes a slotted motorized track member mounted to a vertical wall structure of a building and extending across the top of an opening in the wall. It also includes at least two panels mounted to the track and covering the wall opening while being in a position where the panels are parallel and coplanar with one another. The motorized track member has at least one motorized actuation system enabling one panel to move forward away from the opening thereby freeing the track for the second panel to laterally slide behind the first panel. The panels become stacked in a parallel superimposed position in relation with one another. In the stacked position, the panels cover a portion of one end of the opening while completely uncovering a potion at the other end of the opening.
