  • Patent number: 10588435
    Abstract: An adjustable easel support apparatus and method for forming. The easel support apparatus has selected adjustment features facilitating options of supporting an object. As a table easel, the support posts of the apparatus standing in an upright position and connected to a rigid material, can be adjusted up or down to a desired slant. Users of the table easel could be calligraphers, artists, illustrators, painters, not excluding others. Removable legs of the apparatus further reduce the angle of an attached rigid material providing another alternative slope. The removable legs could have protective non-skid product applied to enhance immovability in either position stabilizing against sliding and pivotal movement. The apparatus is small, portable and light weight.

  • Patent number: 8870148
    Abstract: A space saving, door-mountable artist's easel with a framework adapted to receive and hold an artist's canvas, art panel, clipboard, or some other item that would normally be affixed to an easel with a mounting bracket attached to the frame so the entire device may be hung on a door. The easel can be used while mounted to the door it is stored on. In one example, a front pivoting frame enables the mounted piece to be extended outward from a back stationary frame. A height adjustment mechanism allows the mounted piece to be raised or lowered to a desired position, enabling the artist to stand or sit. The compactness of the easel enables an art piece being worked on to be left mounted to the easel for drying or viewing, and the door can still be opened and closed normally with the easel mounted to it.

  • Patent number: 5205526
    Abstract: A collapsible display easel is provided which can be easily extended into a sturdy, erect easel for holding display material, and easily retracted and folded into a compact configuration for transport. The display easel includes a two-legged supporting stand, a vertical brace, and one or more crossbar members. The display material is held against the vertical brace between the crossbar members. The legs are provided with extending support feet for securely supporting the easel in an upright position. The various components are connected by sliding or pivoting attachment mechanisms which allow the components to be easily extended or retracted. The sliding and pivoting connection mechanisms are manually operable and do not require the use of any tools or special equipment. The display easel is retracted into a compact configuration solely by pivoting or sliding the various components with respect to each other, and does not require the disassembly of any of the components.

  • Patent number: 5170983
    Abstract: A bookholder with a base member having a longitudinally extending base portion forward from a U-shaped rod defining a first planar surface; a support member having a longitudinally extending support portion formed from another U-shaped rod defining a second planar surface; a book carrier mounted on the support member having book-supporting ledges; and a transverse coupling member with pairs of holes arranged to receive and hold both the base portion rod and the support portion rod so the first and second planar surfaces intersect at a preselected included angle. The book carrier is movable along the support member to adjust the height of the book carrier with respect to the coupling member. The base member rod is movable with respect to the coupling member between a first "suspending mode" position when the selected included angle is approximately between 90.degree. and 130.degree., into a second "table supporting mode" position when the selected included angle is between 90.degree. and 50.degree..

  • Patent number: 5005795
    Abstract: An easel having a pair of segmented front legs and a segmented rear leg member with the legs and segments slidably joined by dovetails and dovetail grooves for varying easel height. The front leg segments, in addition to being extensible, are pivotally joined to the main members of the legs to permit angular positioning of the front leg segments to the vertical to serve as the front legs of the drafting table configuration. In this configuration, the upper ends of the main members are positioned downwardly along the rear leg member to provide a sloping, workpiece supporting surface in the nature of a drafting board. A detachable cross member serves to brace the vertical front leg segments against swaying while a brace assembly braces the connection between the main leg members and the rear leg member.

  • Patent number: 4979717
    Abstract: A tripod easel with a pair of front legs that are held slightly wider apart at the foot than at the top includes a retaining mechanism for retaining a canvas holder in place which utilizes a portion of the weight of the holder itself or a portion of the sum weight of the canvas holder and the load thereon as the caulking force acting on the sides of the legs, thus providing an easy to use and secure mechanism for holding the canvas holder in place.

  • Patent number: 4955576
    Abstract: A portable writing board mountable for use on a steering wheel of a vehicle and also entirely stable for writing use when rested upon any flat surface. The board has a platform member which has substantially parallel side edges, a lower edge, and a curved upper edge approximating the curvature of the outer diameter of a vehicle steering wheel. A retaining collar depends from the curved upper edge and is unified thereto. The retaining collar consists essentially of a depending skirt portion and a flange-like portion directed radially inwardly from the skirt portion to thereby form a recess capable of accommodating the rim of a vehicle steering wheel. The most depending portions of the retaining collar form a bottom surface which extends continuously along the entire curvature of the retaining collar, and lies in an imaginary plane intersecting the platform at an axis line perpendicular to the side edges of the platform and located at the lowermost bottom edge of the platform.

  • Patent number: 4793083
    Abstract: A sign panel holding system of the type used by real estate agents or the like, comprising a normally upright post and two holding members securable to a post at virtually any point of the overall length thereof. The holders are each provided with at least one but preferably two parallel transverse members defining a pair of parallel slots. The lower holder has the slots turned upwardly to engage lowermost edges of a pair of normally generally rectangular panels. The upper holder is positioned upside down and is slideably adjusted along the post to grip the top edges of the panel to thus secure the panels fixedly to the associated post. The advance in the art is particularly in structural simplicity of the device and in its versatile use with panels of different size. The invention also allows the placement of the panels at selectively different levels of the post.

    Abstract: A copy stand for shifting a cursor by a motor one line on a copy at a time in which a cursor holder is coupled to bend slightly and sandwich an endless belt driven by the motor. At the driving time by the motor, a coupling force works strongly by a tension of the belt to shift the cursor by the motor and when the cursor is to be returned to its upper end, the cursor can be easily shifted manually while the belt is stopped.
