A drop bar is joined to the bottom bracket arm and to which one end of the awning cloth is fastened. A fabric guide is provided for glide-propping the awning cloth in the area above the swivel joint. A continuous center carrier is located in fixed position in a longitudinal direction parallel to the fabric roll, and has a free end and another end. The hinged joint member is attached in tiltable fashion on the fixed center carrier. The fabric guide is located on the free end of the center carrier and facing away from the base member.

Abstract: An insulation and weatherstripping arrangement and associated method for a rolling door includes an insulation supporting member to support a block of expanded polystyrene or similar insulation inside a vertically extending cavity disposed between a guide track and a wall. Most advantageously, metallic parts disposed on the inside of the door are thermally isolated from metallic parts disposed on the outside of the door. Additionally, inner and outer weatherstrips are used for further minimizing heat loss.

Abstract: An improved connector for display systems such as those used at conventions, public meetings, and the like to display advertisements, merchandise and such. This connector is in the form of an angle channel member formed from aluminum or other suitable material with a plastic U-shaped channel member affixed thereinto to provide a relatively rigid and yet flexible connection which can be readily assembled and disassembled as well as having the capacity to receive additional structural members during use.

Abstract: A fabric drapery system having a unique decorative appearance, by providing a pair of fabric drapery modules to be supported on a conventional drapery traverse rod system or the like, wherein each drapery module comprises three fabric drapery front panels extending the full height of the drapery module to form outwardly facing substantially flat panels bounded laterally by drapery seam formations at their vertical edges with an intervening rearfold panel between each pair of front panels. The middle panel of the three front panels is foldable rearwardly into a collapsed position when the drapery is retracted to opened position while the outermost panels adjacent the middle panel are retained in fully extended flat condition so that the outermost panels of the pair always remain in a common vertical plane, and the intervening rearfold panels remain in folded condition continuously.

Abstract: A thermally insulating transparent wall element comprises a plurality of paraxially, adjacently arranged evacuated transparent tubes each having an axially arranged shaft journalled therewithin, an elongate sunshade strip being mounted on each shaft. A ratchet wheel is supported on one end of each shaft and has at its circumference engaging elements situated at the same angular distance from one another. An externally operable pawl cooperates with the engaging elements of the ratchet wheel to advance the same in step-wise manner. Means is provided to drive the pawl; and a member is coupled to the pawl drive means for latching the ratchet wheel at the end of each movement step, such member being releasable from the ratchet wheel by the pawl drive means just before the start of the next movement step.

Abstract: A device for driving and stopping a roll blind including a blind cloth and a winding roll for winding up and unwinding the blind coth, which includes a clutch mechanism which is actuated to its ON- and OFF-positions by drawing the blind cloth downward. In the cloth lowering operation the clutch mechanism is held in ON-position in order to stop the blind cloth at a desired position and in the cloth raising operation the clutch mechanism is actuated to the OFF-position by slightly drawing the blind cloth downward, thereby allowing the blind cloth onto the winding roll.
