Abstract: An adjustable track means for louver-type drapes or blinds having a telescoping supporting frame and telescoping driving means for drawing the drapes transversely and for rotating the individual louvers is described.

Abstract: A bracket structure for use in hanging and pleating decorative wall fabrics, providing an elongated flat sheet metal backing strip with a plurality of generally U-shaped cross section extensions formed at uniformly spaced intervals along the length of the strip, a plurality of tabs formed in the strip both in the intermediate flat sections and in the curved portion of the U-shaped extensions for engaging and securing fabric with the outer end portions of the tab having a reversed bend which locks the fabric in position, and a rigid facia strip having the same configuration as the sheet metal backing strip and secured thereto with the fabric between the backing and the facia strips to provide protection for the connection of the fabric to the bracket.

Abstract: A cover for servicing holes in automotive service stations consists of a band of pivotably connected support members, the ends of which are supported on the longitudinal hole edges. The band is displaceable longitudinally in opposite directions by at least one motor drive to open and close the servicing hole. During the opening movement the band is moved downwardly at one front end of the longitudinal hole. In order to avoid a broadening of this region of the hole the support members are telescopically assembled and are compressed to a reduced length in this region than in the covering region of the servicing hole.

Abstract: A venetian blind, comprises, a plurality of slats, with a pin extending from either side of each slat and a pair of casings having longitudinal slots for receiving the pins and permitting the longitudinal movement of the slats. The slats are connected by a collapsible ladder support which effects the pivoting of each of the slats as they are extended and retracted. A driven windup shaft is rotatably mounted on the casings and carries a draw member in the form of a chain thereon. An upper carriage part is connected to one end of the draw member. The upper carriage part has a stop surface which is abutable against an end stop to stop the movement of the draw member in one direction. A lower carriage part is slidably connected to the upper carriage part and connected to a lowermost one of the plurality of slats.

Abstract: A unique thermal barrier is provided for use with a window in a building construction. The thermal barrier comprises a sheet at least the same size and preferably somewhat larger than the size of the window and one edge of the sheet is secured to the building above the window. A plurality of slats are secured to one side of the sheet so that the slats extend substantially horizontally and are parallel and adjacent to each other. In addition, the slats are constructed of a thermal insulating material such as a polystyrene foam. A decorative covering is also secured to the sheet so that the slats are positioned in between the decorative covering and the sheet. In addition, a cord is operable to move the sheet with its attached slats between a lower position, in which the sheet covers the window opening, and an upper position in which the slats are folded upon each other thus exposing a substantial portion of the window opening.

Abstract: An integral window unit comprising a sill member, a header member and a pair of jamb members interconnected to form a generally rectangular window frame. The jamb members have first and second pairs of track means each pair of which slideably receives a prime window sash and third and fourth pairs of track means each pair of which slideably receives a storm window sash. The distance between the track members in the first pair is greater than the distance between the track members in the second pair which in turn is greater than the distance between the third pair which is greater than the distance between the fourth pair. At least one pair of track means is in overlapping relationship with the adjacent pair of track means. A thermal barrier is provided in the window frame between the second and third pair of track members to minimize heat loss therethrough and a fifth pair of track means is provided adjacent the thermal barrier for slideably receiving a screen member.

Abstract: A transparent, flexible curtain with spaced access points is provided for installation over the opening of a display type open refrigerator of the sort used in retail food markets. The curtain is comprised of a plurality of elongated, flexible, transparent panels secured at one end to the top or rear edge of the refrigerator cabinet and extending in overlapped relation across the cabinet opening. The edges of the panel are tubular and a colored sleeve may be added to make access points between adjacent panels more readily visible. The curtain retains cold air within the refrigerator and allows the food products to be clearly visible to the customer. Goods are removed by the customer reaching in between adjacent panels which separate easily and return to a closed position when the customer's hand is withdrawn.
