Definitions

  • This invention relates to document support apparatus, and more particularly relates to a universal document support stand for selectively and fixedly positioning a document holder for viewing at a computer workstation and other visual reference situations.
  • Description of the Prior Art The term "document” hereinafter refers to a single page or a multiple number of pages.
  • document holder refers to that type of device which is adapted to secure a document, such as in the form of a book, spiral bound manual, loose-leaf binder, conventional copyholder stands or the like, as well as those devices which have been modified by a present applicant (Hegarty) in a previously filed application having U.S. Pat. No. 4,925,146 which is herein incorporated by reference.
  • multi-positionable hereinafter refers to the ability to pivot about one or more axes of rotation.
  • symmetrically functional hereinafter refers to the ability of a support stand, or a member of such a stand, of the present invention, to operate for its intended purpose when positioned to the left or the right of its operator's central location.
  • the term "relocatable” hereinafter refers to the ability to be engagably moved from one support location to another.
  • the term "fixed supportive location” hereinafter refers to the placement of a member of the stand of the present invention at a specific fixed location on the main support body of the stand, with that location providing the supportive forces necessary for that member to function for its intended purpose in the present invention.
  • Document support stands for supporting a document or document holder in space are well known in the art and are generally referred to as "suspended copyholder stands".
  • Many conventional stands are designed to be supported by a bracket clamped to the edge of a desk and to suspend the document holder in space through the cooperation of various types of mechanical structures utilizing an assortment of joints, springs and/or adjusting knobs.
  • a further disadvantage with conventional suspended document holders is that they require a considerable amount of desk and air space in order to position a document for viewing.
  • Many suspended document holders require the edge of a desk in order to be supported.
  • these type of document holders require that the space throughout which the suspended arm moves be free of any obstructions such as walls, shelving or lighting fixtures. Consequently, not only must the desk surface be free of barriers but the arm, being boom-like in movement requires considerable open space, both vertically and horizontally, in order to freely move the boom-like arm when positioning a document for viewing.
  • a copyholder so constructed does nc require extending and pivoting arms to change the position of its viewing side.
  • Many copyholders such as the Workstation Plus (TM) copyholder, Model No. 21115 (manufactured by the Fellows Manufacturing Company of Itasca, Illinois), ignoring the benefit of gravity, use an extending arm which initially pivots about a horizontal axis thereby requiring frequent manipulation of its adjustment knobs in first requiring the fixating of the horizontal and then the vertical position of the copyholder's viewing side.
  • the universal document support stand includes a projecting, multi-positionable article support stand which works in combination with an attachable multi-purpose and multi- positionable document holder for fixedly projecting a document, or document holder, at a multiplicity of locations in space.
  • the projecting, multi-positionable article support stand includes a main support body, a relocatable multi- positionable arm and a relocatable support bracket.
  • the main support body may be formed in the shape of a right angled stationary support member.
  • the body has a horizontal member integrally formed with a vertical member.
  • the horizontal member is provided to be positioned on a workstation surface and to allow a video display monitor to rest atop it thereby securing the vertical member in a stable upright position on either side of the monitor.
  • the vertical member includes a front member relocating side, constituting the mounting side of the stand. Consequently, the member relocating side includes a mounting device for removably mounting the relocatable and multi- positionable arm and the relocatable support bracket on the main body of the stand.
  • the mounting device is located in the surface of the front member relocating side and is formed as a slot having a symmetrical pattern.
  • the slot is C- shaped in cross section, and defines a T-slot having an exposed open end.
  • the exposed open end of the T-slot provides for access to a symmetrical mounting device which provides for the ability to mount and selectively position and relocate both the multi- positionable arm and the support bracket.
  • the symmetrical pattern provides support, both vertically and horizontally, when positioning and relocating the mounted arm and bracket members.
  • the relocatable multi- positionable arm includes a multi-positionable fitting and a cooperating elongated cylinder.
  • the multi-positionable fitting includes a socket housing and a member for mounting the socket housing on the body.
  • the cooperating elongated member includes as one integral unit: a disk, an elongated cylinder, and a fitting, at the distal end of the member, for receiving attachable article holders.
  • the cooperating elongated cylinder is removably mountable on the socket housing member and provides for the pivoting of the elongated cylinder.
  • the relocatable support bracket includes a solid body formed in the shape of a corbel bracket having three sides.
  • the body includes: a window-like cutout, within its structure, which creates a bounded lower horizontal support surface; and a member for mounting the relocatable support bracket on the stand.
  • the member for mounting the socket housing on the body in its preferred form is circular, T-shaped in cross-section, and fitted to a side of the socket housing member.
  • the T-shaped member of the socket housing is slidably received by the C- bracket of the body through the C-bracket's exposed open end, so that the multi-positionable arm may be rotatably positioned, with its housing member supported, at a plurality of locations on the body.
  • the member for mounting the relocatable support bracket on the body in its preferred form is square, T-shaped in cross- section, and fitted to a side of the bracket member. Prior to mounting the bracket on the body the distal end of the multi- positionable arm is passed through the cutout formed in the bracket.
  • the T-shaped member of the bracket body is also slidably received by the C-bracket of the body through the C- bracket's open end so that the relocatable support bracket may be fixedly positioned and supported at a plurality of locations on the body.
  • the relocatable and multi-positionable arm cooperates with the relocatable bracket, which supports a section of the arm member, in positioning and supporting the distal end of the arm member, thereby positioning an attached document holder in a plurality of spatial positions.
  • the main body of the projecting, multi-positionable support stand is integrally formed in the casing of a video display monitor and is provided with a pair of oppositely disposed member relocating sides.
  • Such an embodiment provides for the creation of a symmetrically functional main support monitor.
  • the main support monitor cooperates with a joined projecting arm and bracket member in positioning the distal end of the joined member at a multiplicity of fixed support locations.
  • Either of the just described stands are capable of working in combination with the next member of the universal document support stand, namely, the multi-purpose and multi-positionable document holder.
  • the multi-purpose and multi-positionable document holder is initially provided with two distinct features.
  • the first feature allows the viewing side of the holder to function as a multi-purpose document holder.
  • the multi-purpose feature is provided by the presence of a rotational means on the viewing side's lateral ends which allows the conventional holding means, namely, a biased clip and/or a support ledge to be rotational displaced by the opposite (back) side of the viewing side.
  • a rotational means on the viewing side's lateral ends which allows the conventional holding means, namely, a biased clip and/or a support ledge to be rotational displaced by the opposite (back) side of the viewing side.
  • Such a feature allows the front viewing side to be converted to a an unobstructed planar surface simply by rotationally displacing the conventional holding means.
  • the present feature does not require the removal of the conventional holders from the stand, i.e., biased clip and ledge. Once converted the viewing side is capable of engaging various other types of holders having different mounting requirements because of size or different cooperating engaging means such as Velcro (TM) or a T-rail
  • the second initial feature present in the attachable multi- purpose and multi-positionable stand allows the device to function as a multi-positionable document holder having means to position a document or document holder, mounted on its viewing side, in any one of a multiplicity of positions about three axes of rotation which are mutually supported from a nearby location. Additionally, the device provides for the fixed positioning about each axes through the application of gravity, detents and protrusions and rack/pinion cooperation.
