An elongate shell for forming a slat for a rolling door includes a planar portion having parallel first and second longitudinal edges and formed along the first longitudinal edge with a first arcuate segment and formed along an opposing second longitudinal edge with second arcuate segment, the first and second arcuate segments being positioned on the same side of said planar portion and configured and dimensioned to enable the second arcuate segment of a first shell to be received with clearance within a first arcuate segment of second shell identical to the first shell to form an articulated joint hingedly connecting the elongate shells so they can be pivoted relative to each other. Two identical shells can be oriented to be assembled to form a double-walled slat with longitudinal hooks or claws for assembling a plurality of slats, with or without insulation, into a curtain assembly for a rolling door.

The invention relates to roller blind slats having a profile which is shaped by flat sheet metal in a rolling step. A single-pieced roller blind body is associated with the roller blind slats. The roller blind body is formed with a slot on the underside thereof and a hooked strip is provided on the top edge thereof. The slot part is approximately 20% on the total surface of the roller blind slats.

The invention is directed to a guide mechanism for plates and a sun protection system under a translucent sun roof in an automobile. The invention comprises at least two plates having guide blocks non-rigidly attached thereto and provided at each end of the plates. The guide blocks are adapted to slide within two opposing guide tracks located within guide sections in the roof of the automobile. Each of the guide blocks includes an elastic spring device which coacts with the plate whereby uneven torque forces caused by sliding of the plates and which causes friction at the guide track is minimized.

A heat insulating shutter device includes a coiled shutter housing provided on an upper edge portion of a building vertical wall which defines an opening formed in the wall and having a sliding window. The housing has an outlet in its lower end and a drive horizontal roller in its interior for winding and unwinding a shutter. The shutter comprises a multiplicity of slats interconnected so as to be wound up to a coiled form and is connected to the roller by striplike attaching members. Opposite side edge portions of the wall defining the opening each have a hollow side frame, and a lower edge portion of the wall forming the opening is provided with a hollow lower frame. Grooved shutter guides, which are opposed to each other and each attached to an inner wall of the side frame, have movably fitted therein respective opposite side edge portions of the shutter. The slats of the shutter, the side frames and the lower frame each have a hollow portion filled with urethane foam serving as a heat insulating material.

Security proof shutter structure applicable to windows, doors, store or garage fronts, utilizing slats constructed of steel or the like. A special S-shaped spring linkage means is secured to respective ends of the slats. The lower hook of each linkage means being engaged with the upper hook of the adjacent linkage means to provide a rotatively operative linkage between adjacent slats without fixed attachment.The hooked linkage is well adapted to independently install or remove any one slat on site and to independently control by sliding the closing of the louvre spacing between adjacent slats or moving apart from each other. The louvre spacing between adjacent slats can be progressively closed or opened. The full lowering takes place with opened louvre spacing and by continued lowering the progressive closing of the louvre spacing between adjacent slats will take place. The winding around the upper roller takes place with fully opened louvre spacing. The series of slats are supported by sliding on opposite ends within vertical U-shaped channels.A special locking device provides two stopping means disposed on the periphery of the pulley and a flexible control rod operating by sliding between the two stopping means. The operator can actuate the control rod to enter into or withdraw from the space between the two stopping means, whereby the shutter can be locked at any position or louvre spacing so that it provides ventilation or communication and full protection.
摘要:
An automatic protection device for a roller blind to prevent unauthorized raising of the blind from the outside by means of two-arm toggle joints whose lever ends are linked at one of the adjacent roller blind staves so that upon unauthorized raising the free toggle joint moves against the flange of U-shaped guide channel in combination with a compensating member in the face region of the upper roller blind stave and movable relative thereto exerts on the locking teeth of the free toggle joint through the action of an additional force means such as an elastic compressible material, a pressure by which the locking teeth are brought against the flange of the guide channel. This not only assures positive locking but also acts to compensate for differences in stave spacings and widths of guide channels thereby reducing manufacturing and inventory costs.
摘要:
An interlocking system of structural elements of a wide range of utility made up of a series of said elements having opposite, connected ends. The elements each have one end with projecting arms, and another end with means for engaging the arms effecting a hinged connection between the adjacent elements of the system. The system comprehends mating, rectilinearly formed joints effecting a tight seal at the junctures thereof.
