  • Patent number: 7686063
    Abstract: A drapery system for moving a suspended drapery fabric allows the drapery fabric to be decoupled from a drive system, such that the drapery fabric may be manually moved. The drapery system comprises a master car comprising a driven portion and a non-driven portion. The driven portion is coupled to a drive belt of the drive system, while the non-driven portion is coupled to the drapery fabric. The master car comprises a spring having a snap adapted to be received in a snap-receiving structure, such that the driven portion is coupled to the non-driven portion. The non-driven portion is operable to move in response to movement of the drive belt to move the drapery fabric when the non-driven portion is coupled to the driven portion. The non-driven portion is operable to be decoupled from the driven portion, such that the position of the drapery fabric may be manually adjusted.

  • Patent number: 7681771
    Abstract: A stapler movable between a rest position and a stapling position and having a front end and a rear end. The stapler includes a base, a staple magazine coupled to the base and configured to hold staples, and a driver blade operable to drive staples out of the staple magazine during stapling operations. The stapler further includes an elastic member coupled to the driver blade and operable to move the driver blade during stapling operations. The elastic member utilizes potential energy to move the driver blade during stapling operations. The driver blade is positioned above the staple magazine when the stapler is in the rest position and the magazine is extendable from the front end of the stapler to allow a user to load staples in the magazine. The stapler is configured such that only the potential energy of the elastic member can operate the driver blade during stapling operations.

  • Publication number: 20100043985
    Abstract: A pleated roller shade system allows a thin flexible shade fabric, such as, for example, silk, to be wrapped around a roller tube. The pleated roller shade system comprises a drive system, such as a motor or manual drive system, for controlling of the rotation of the roller tube. The roller shade system may comprise a pleating hembar that is contained within a hembar pocket of the shade fabric and has a non-linear shape for causing the shade fabric to hang with a plurality of pleats. The roller shade system may also comprise an elongated pleating assembly mounted parallel to the roller tube and having a fabric-receiving opening that defines a non-linear path. The shade fabric may be received through the fabric-receiving opening and folded by the pleating assembly, such that the shade fabric is wrapped around the roller tube in folds as the roller tube rotates.

  • Publication number: 20100038039
    Abstract: A pleated roller shade system allows a thin flexible shade fabric, such as, for example, silk, to be wrapped around a roller tube. The system comprises a pleating bar mounted parallel to the roller tube and having a fabric-receiving opening that defines, for example, a serpentine path. The shade fabric is received through the fabric-receiving opening and is folded by the pleating bar, such that the shade fabric is wrapped around the roller tube in folds as the roller tube rotates. The shade fabric is neatly wrapped around the roller tube (i.e., bunching of the shade fabric is avoided) and is stored out-of-sight when rolled up.

  • Publication number: 20100023422
    Abstract: Import/export transactions whereby an item is to be transported from one country to another are automated. An invoice containing a list of one or more part numbers is entered in at a web site and loaded to a server containing a database. A database is of part numbers and their corresponding tariff classification numbers. The uploaded invoice will be compared to the database to output a data record whereby the one or more part numbers uploaded in the invoice now have tariff classification numbers and daily calculation associated therewith This data record can then be accessed over the Internet at another web site by a customs broker for use in transmitting a report to a customs entity.

  • Patent number: 7599612
    Abstract: Calibration of a motorized roller shade is accomplished by calculating a radius of a roller tube and thickness of a shade fabric rotatably supported by the roller tube. First, a lower edge of the shade fabric is moved to a first position at a first linear distance from a predetermined position. Second, a first number of revolutions of the roller tube between the first position and the predetermined position is determined. Next, the lower edge of the shade fabric is moved to a second position at a second linear distance from the predetermined position and a second number of revolutions between the second position and the predetermined position is determined. Finally, the tube radius and the fabric thickness are calculated from the first and second linear distances and the first and second numbers of revolutions. The tube radius and the fabric thickness are used to control the linear speed of the lower edge of the shade fabric.

  • Publication number: 20080035281
    Abstract: A hembar includes front and rear walls and top and bottom spline channels adjacent a top and a bottom of the hembar. Each spline channel receives a spline in an oblique orientation to a vertical line and is arranged to conceal the channel from any viewing location in front of the hembar. A shade fabric is received in the channels through longitudinal slots and the splines are received through an open end. A notch opposite the slot receives part of the shade fabric to facilitate spline insertion. A pocket for a weighting element is off-centered such that it is closer to the rear wall. The hembar is assembled using a support member having obliquely angled walls to support the hembar with one channel horizontally oriented. The front and rear walls of the hembar may be covered by the shade fabric in a full wrap option.
