  • 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.

  • Patent number: 6971624
    Abstract: An adjustable support assembly for a data entry/interface device for computers or the like such as a keyboard, keypad, laptop/notebook computer, personal data/digital assistant, tablet PC, trackball or the like provides selective adjustment of both height and angular orientation or tilt for the data entry/interface device with respect to the work surface on which it is mounted. A pair of actuator handles are pivotally mounted in close proximity to one another on a data entry/interface mount to allow either independent or simultaneous operation with one hand by the device operator to control height and/or tilt. The actuator handles are connected to individual adjustment clamp assemblies by separate flexible cable actuators. Depression of each actuator handle pivots at least one clamp bar connected to the cable actuator between clamping and release positions to lock or allow reciprocation of a rigid adjustment bar extending through an aperture in the clamp bar.

  • Patent number: 6779855
    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 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 independent 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: 6142596
    Abstract: An under mounted drawer slide assembly with a cabinet channel and drawer slide that interface so as to avoid the necessity of creating an opening in the lower portion of the drawer's rear panel. A bracket for the drawer slide is formed to fit around the lower edge of the drawer's rear panel and includes an elongated roller mounted thereto at a height below the lower edges of the drawer panels. The roller has a smaller diameter than conventional rollers but is elongated to provide greater support and stability to the drawer slide system. This roller travels within a generally C-shaped channel that is also located beneath the lower edges of the drawer panels. Both the roller and channel are low profile components so as to fit within the tight space constraints between the lower edges of the drawer and the cabinet opening, thereby avoiding having to mount the channel and slide within the recess created by the bottom panel of the drawer.

  • Patent number: 4988214
    Abstract: The specification discloses a sequential drawer slide having a simple yet positively reliable sequencing mechanism. The mechanism includes a gravity operable control lever carried by the intermediate slide member and shiftable at the transition point between two positions, each wherein either the cabinet or drawer slide member is interlocked with the intermediate member. The single control lever therefore provides full sequencing of the slide members.
