  • Patent number: 10820648
    Abstract: A method for tailoring a compression garment including a first sheet and a second sheet, each having a first lateral end and a second lateral end, at least one strap for holding together the first lateral end of the first sheet and the first lateral end of the second sheet. The strap is tightenable to establish a compression level to a human limb or body part. The method includes: adjusting the strap; draping the compression garment around the limb or the body part; holding the second lateral end of the first sheet and the second lateral end of the second sheet together to pull the first sheet, the second sheet and the strap into contact with the limb or body part; marking a cutting line on one or both sheets; cutting the sheets along the cutting line; and splicing together both cut ends with at least one splicing element.

  • Patent number: 7533946
    Abstract: A closing device for drawers, the device having a housing with a holding notch and a slider having a resilient latching arm that is bendable to engage the holding notch, as well as a spring that engages the housing and the slider to urge the slider to a rearward position relative to the housing. The resilient latching arm has a slot adapted to receive a pin, whereby as the drawer is moved from its closed position, the relative movement of the pin advances the slider to a position where the resilient latching arm engages the holding notch and the drawer is free to mover further outward without influence of the closing device. As the drawer is moved rearward toward its closed position, the relative movement of the pin will cause it to engage the slot in the resilient latching arm, further causing it to release from the holding notch and to be urged by the spring to move the drawer toward a closed position.

  • Patent number: 7484817
    Abstract: Interlocks for file cabinets and the like which generally prevent more than one drawer from being opened at a given time. The interlocks include a cable which is changeable from a slack condition to a taut condition. In the taut condition, the interlocks prevent the associated drawer from being opened. In the slack condition, the interlock allows the associated drawer to be opened. The interlocks may be used in conjunction with a lock that selectively changes the tension in the cable from a slack condition to a taut condition and vise versa. The interlocks may be constructed to exert a tension on a cable that is independent of the pulling force exerted on a locked drawer. Alternatively, the interlocks may be constructed to exert a force on the cable that is a small fraction of the pulling force exerted on a locked drawer.

  • Publication number: 20070282232
    Abstract: A therapeutic device that provides an auxiliary strap holding position for at least one strap where the strap can be temporarily attached to the auxiliary strap holding position on the device to prevent tangling or connection to an unintended surface when the strap is not in a position used to attach the device to a part of a user's body. The auxiliary strap holding position enhances the ease of donning, doffing, and storing the device.

  • Patent number: 7293845
    Abstract: Interlocks for file cabinets and the like which generally prevent more than one drawer from being opened at a given time. The interlocks include an elongated, flexible member, such as a cable, which is changeable from a high slack condition to a low slack condition. In the low slack condition, the interlocks prevent their associated drawers that are closed from being opened. In the high slack condition, the interlocks allow their associated drawer to be opened. The interlocks may be used in conjunction with a lock that selectively changes the cable from a high slack condition to a low slack condition and vice versa. The interlocks may be constructed to exert a force on the cable that is a small fraction of the pulling force exerted on a locked drawer.

  • Patent number: 7063398
    Abstract: Interlocks for file cabinets that prevent more than one drawer from being opened at a given time include an elongated, flexible member, such as a cable, which is changeable from a high slack condition to a low slack condition when one of a number of associated drawers is opened. In the low slack condition, the interlocks prevent their associated drawers that are closed from being opened. In the high slack condition, which exists when the drawers are closed, the interlocks allow their associated drawers to be opened. The interlocks may be used in conjunction with a lock that selectively changes the cable from a high slack condition to a low slack condition and vice versa. The interlocks may be constructed to exert a force on the cable that is a small fraction of the pulling force exerted on a locked drawer.

  • Patent number: 6719386
    Abstract: A precision drawer slide, employing two or more members, wherein, one member is fastened to a cabinet wall, or carcass, and the other member is fastened to a drawer. The member fastened to the cabinet wall comprises a profile that has a “hat” section appearance that generates a surprising amount of rigidity when installed in desk and file cabinets of various kinds. The drawer and cabinet member are also strategically foreshortened and rear-shortened respectively. Other variations or embodiments include the usage of a novel quick disconnect system for the easy installation and removal of a drawer from the drawer slide assembly, as well as the inclusion of a roller bearing component for generation of a progression movement in the drawer slide itself.

  • Patent number: 6575777
    Abstract: An electrified partition system having a plurality of panels interconnected with each other to form a plurality of work spaces. A plurality of receptacles are mounted in raceways located in the panels with each receptacle including a housing and a plurality of conductors extending from one end of the housing to the other end of the housing. The conductors terminate in respective terminals and define individual circuits. At least one electrical socket is disposed in a face of each of the receptacle housings and include a plurality of connectors positioned behind respective apertures in the housing face to receive a standard multi-pronged electrical plug. The connectors are connected to respective conductors which are fewer in number than the plurality of conductors so that some of the conductors pass through the housing electrically isolated from the connectors. Multi-circuit cables connect the terminals of the receptacles to form an electrical network.
