Definitions

  • the present invention relates to a hand held support assembly for supporting devices or appliances to facilitate a user moving the devices or appliances over an area.
  • the present invention relates particularly, although by no means exclusively, to a hand held support assembly for supporting a device in the form of a scanner for scanning library books and/or files in shelves and/or cabinets as part of a document management system.
  • the present invention relates particularly, although by no means exclusively, to a hand held support assembly for supporting a device in the form of a scanner that is based on radio frequency identification (“RFID”) technology.
  • RFID radio frequency identification
  • Barcode technology has been used since the early 1980s for tagging articles in supermarkets, retail ⁇ stores, libraries, etc. Accordingly, barcode technology is one option for use in management systems.
  • barcode technology requires line-of- site and physical alignment when reading barcodes and is limited to reading one barcode at a time. This is very time consuming and if articles to be read (such as library books or files) are in shelves or cabinets, the articles have to be physically removed from shelves or cabinets one at a time and read and thereafter placed back in original positions .
  • RPID technology is not only capable of reading individual library books or files on shelves or in cabinets but is also capable of reading multiple books or files within an effective scanning zone of a RFID scanner. Consequently, document management systems using RFID technology are potentially considerably quicker options than document management systems using barcode technology.
  • RFID technology has potential to drastically improve operational efficiency by substantially reducing the amount of time that a library would have to be closed to perform the audit and would result in substantial manpower savings.
  • the strain and fatigue is due to the need for a user to manipulate the scanner by twisting movement of the arm/hand grasping the scanner and/or by the user bending over or crouching down as required in order to maintain the scanner within a preferred range of orientations relative to the library books as the user moves the scanner over an area of shelves .
  • a particular object of the present invention is to provide a hand-held RFID scanner assembly that facilitates a user moving a RFID scanner in an ergonomically effective and user-friendly manner over an area.
  • a more general object of the present invention is to provide a hand-held device/appliance assembly that facilitates a user moving a device/appliance in an ergonomically effective and user-friendly manner over an area
  • a device or appliance assembly that includes a device or an appliance and a hand held support assembly supporting the device/appliance for movement relative to the support assembly, and the support assembly includes:
  • a hand-held support assembly for supporting a device or an appliance, the support assembly including:
  • a user can adjust the position of the device/appliance so that the device/appliance continuously is within an optimum range of orientations relative to an area over which it is necessary to move the device/appliance as the user moves the device/appliance over the area.
  • a user can adjust the position of the device/appliance with minimal twisting movement of the arm/hand of the user that would result in considerable strain or fatigue over a period of time.
  • the means supporting the device/appliance on the arm is a pivot connection between the device/appliance and the arm.
  • the means for adjusting the angular relationship of the device/assembly and the arm (“the adjustment means") includes a hand-grip lever that is pivotally mounted to the handle and a series of mechanical interconnections that interconnect the lever and the device/assembly, whereby depressing and releasing the lever by applying and releasing finger pressure to the lever moves the device/assembly through the range of angles relative to the arm.
  • the mechanical interconnections include a cam assembly connected to the lever, a wire connected at one end to the cam assembly and at the other end to a biasing means connected to the arm or the handle, and the wire being arranged to extend from the cam assembly along the length of the arm and around a pulley that forms part of the device/appliance support means on the arm and back along at least part of the length of the arm to the biasing means, whereby in use pivotal movement of the lever in response to finger pressure applied or released by the user actuates the cam assembly and the cam assembly causes movement of the wire along the arm, and the movement of the wire causes rotational movement of the pulley, and the rotational movement of the pulley causes movement of the device/assembly through the range of angles relative to the arm.
  • the device/appliance may be any device/appliance .
  • the device/appliance may be a scanner for scanning library books and/or files and/or other articles in shelves and/or cabinets.
  • the scanner is an intelligent radio frequency (“RFID”) scanner.
  • RFID radio frequency
  • the RFID scanner includes an antenna plate.
  • the RFID scanner can be mounted to the arm so that scanner can move within a range of angles of 35-180° relative to the arm, with the angles being defined by an included angle between the plane of the antenna plate and an axis of the arm.
  • the handle may be adapted to be grasped by one hand.
  • the handle may be adapted to be grasped by both hands .
  • the arm may be a fixed length.
  • the arm may be an adjustable length.
  • the arm may be a telescopic arm.
  • Figures 1 and 2 are front and side views respectively of a preferred embodiment of a scanner assembly that includes a RFID scanner and a hand held support assembly supporting the scanner in accordance with the present invention
  • Figures 3 and 4 are cross-sections through the scanner assembly which illustrate the mechanical interconnections between the hand grip trigger of the support assembly and the scanner and the operation of the support assembly to adjust the position of the scanner between the positions shown in Figures 3 and 4;
  • Figures 5 to 8 illustrate a range of different operational positions of the scanner assembly in relation to shelves holding library books.
  • the scanner 7 is positioned relative to the arm 5 so that the scanner 7 and the arm 5 describe an included angle ⁇ of 35°.
  • the position of the scanner 7 can be adjusted from that shown in Figure 1 to a position in which the scanner 7 and the arm 5 describe an included angle of approximately 180°.
  • the support assembly includes :
  • the support assembly further includes a means for adjusting the angular relationship of the scanner 7 and the arm 5.
  • the adjustment means includes a trigger-type lever member 9 located in the handle 3 and a series of mechanical interconnections between the lever member 9 and the scanner 7 that make it possible for a user to adjust the position of the scanner 7 relative to the arm 5 by applying and releasing finger pressure to the lever member 9.
  • the lever member 9 is pivotally mounted to the handle 3 via a pivot connection 13 for rotation about the axis of the pivot connection.
  • the lever member 9 includes a trigger 39 that can be depressed by finger contact of a user.
  • the lever member 9 also includes an arm 15 that is connected to a cam assembly.
  • the cam assembly includes a pulley 23 that is mounted to the handle 3 via a pivot connection 25 for rotation about the axis of the pivot connection.
