Abstract: A roller shutter includes a plurality of horizontal slats (I) each provided with a flat lug (22) projecting from each end and mounting inside guide rails (V) on both sides of the window or door. Each slat has its upper edge (3) bent in a hook-profile in one direction and its lower edge (4) bent in a hook-profile in the opposite direction. The upper edge of each slat engages the lower edge of the adjoining slat in such a manner that all slats of the shutter are in firm engagement wile their axes are at a possible maximum distance from each other, but are releasable from each other by their rotation about their axes whenever the shutter is lowered with the lowermost slat resting on the window sill with the slat axes at a minimum distance from each other. Rotation of the slats is carried out by slotted rotors (III) rotatably mounted in the guide rails (V) whereof each rotor slot engages one flat lug (22), at minimum distance.

Abstract: The present invention relates to a tray table for invalid chairs operable in two modes, and methods for making and operating the tray table. Runners on the tray slide into brackets mounted to the arms of the chair, thus maintaining the tray in position in front of the patient. A detent mounted to at least one bracket is capable of engaging a hole on at least one runner. In one mode, the detent engages the hole in the tray table, locking the tray table in position on the chair. In a second mode, a sliding block is displaced under the knob of the detent. The detent is thereby maintained in a retained condition such that the runner may freely slide in and out of the bracket.

Abstract: A louverable roller blind has lamellar blind slats (14), similar to Venetian blind slats, hingedly linked at their upper areas to pull chain elements (21, 40) and at their lower areas to adjusting chain elements (23, 41). The blind slats (14) are further laterally guided in stationary guide profiles (31). Pins (32) that connect the adjusting chain elements (23, 41) to the blind slats (14) are spaced apart from a plane in which hinge pins (30) of the adjusting chain elements (23, 41) are located. The hinge pins (30, 32) that link the pull chain elements (21, 40) and the adjusting chain elements (23, 41), as well as swivelling pins (16) of the blind slats (14), are mutually aligned when the roller blind is not used as a Venetian blind. This alignment allows the roller blind to be rolled up without problems in a reduced space and to be used as a Venetian blind with no need for special aids.

Abstract: The hot stick adaptor has two members that are adjustably movable relative to each other. A first one of the members has two separate first ratchet areas. A second one of the members has three separate second ratchet ares. A fastener and spring connect the two members to each other with one of the first ratchet areas and one of the second ratchet areas in interlocking engagement. The two members can be moved away from each other in a first direction, compressing the spring, to disengage the interlocking engagement and thereby allow the two members to be moved in a second direction.
