This application claims benefit of provisional application 60/109,668 filed Nov. 20, 1998.
The invention relates generally to electronic displays having dual display screens used with computers and CAD design equipment, and more particularly to a display system permitting positioning of dual display screens in an infolded “booking” mode, and to a novel dismountable joint for mounting articles, such as display screens. Also disclosed is an interchangeable display screen and mounting.
Computers are readily adapted to operate multiple displays. Paired monitors and screens are useful when large amounts of related information, such as data or graphics, must be compared. Paired monitors can be inconvenient, however, where limited desk space is available. Monitors may be horizontally aligned, or vertically aligned. It is especially desirable to permit swinging of the monitor orientations together into a “booking” mode.
The invention also relates to a novel swingable mounting, which is suitable for mounting a variety of different pieces of equipment and instruments particularly for example video cameras, telescopes, mirrors, and any number of different articles, which it may be desired to swing into a position from which the article is not easily displaced.
The invention also relates to an interchangeable computer display screen, in which one or more of a variety of screen configurations can be connected or disconnected in various configurations with a computer.
In one aspect, the invention provides a display system having two screens and comprising a base, a pair of electronic displays mounted on the base and means for swingably mounting the display screens, for swinging towards one another for convenient viewing. The swinging means includes an arm assembly which supports the display screens on the base. The support for the arm assembly from the base may have an orientation relative to the base in which the display screens are positioned in vertically stacked screen relationship and may also have a different orientation in which the display screens are positioned in a horizontal, side by side relationship. Each display screen has a swingable joint connecting it to the arm assembly to permit adjustment of its angular orientation relative to the other screen. The angular orientation of each of the display screens relative to the arm assembly can thus be set by the user so as to orient each display screen in the desired angular orientation for that operator.
In one implementation of the invention, the arm assembly can be set in one position about a generally horizontal axis relative to the base, and the display screens can be swung together relative to the arm assembly. The arm assembly may be locked in either orientations, typically vertical or horizontal. Each display screen may be permitted to swing only between a pair of angular positions relative to the arm assembly by controls in the swingable joints.
The displays will often be horizontally arranged side by side in their operative angular orientation. It will generally be desirable to minimize the spacing between edges of the display screens whether vertically registered or horizontally registered. To that end, the center-to-center spacing between the display screens is preferably reduced when the screens are swung together.
The swingable mounting joints connecting the display screens to the arm assembly are preferably formed in such a way that they can be preconfigured either for a side by side orientation or for a vertically stacked orientation of the screens, with means being provided on the swingable joints to guide the assembly in one fashion or the other, and the arm assembly is preferably provided with connecting means connecting to the swingable joints, which cooperate with the means guiding the assembly.
The swingable joints are preferably provided with control abutments by means of which the swinging of the displays can be guided and controlled both when in their horizontal side-by-side arrangement and when in their vertically stacked arrangement, and the position and angular displacement of the two screens can be preset by adjustment of such positional controls during assembly.
A further feature of the invention is the provision of a unique form of spring-loaded pivot mount for mounting equipment, such as the display screen. The pivot mount is capable of adjusting the spring pressure on the pivot so that the article mounted on the pivot mount, in this case a screen can be adjusted, when grasped with both hands and moved, but which is otherwise highly resistant to movement due to frictional locking of the pivot mount.
The pivot mount has numerous other uses, other than mounting display screens as will be apparent from the following description.
Further aspects of the invention provide for the interchangeability of screens one with the other, so that larger or smaller screens may be used with the same computer, and so that screens may be used in various different positions.
In some cases the screens may simply be stood on a table. In other cases the screens may be wall-mounted or mounted on some form of base separate from the computer. In other cases the screens may be interchangeably and releasably mountable for example in a vehicle, and they may be configured in pairs so that they may be portable and set up for a multi screen display, for example, for viewing by a number of persons simultaneously.
The various features of novelty which characterize the invention are pointed out with more particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects attained by its use, reference should be made to the accompanying drawings and descriptive matter in which there are illustrated and described preferred embodiments of the invention.
The various advantages of the present invention will become apparent to one skilled in the art by reading the following specification and subjoined claims and by referencing the following drawings in which:
As already explained, the invention in this particular embodiment illustrated, has its application to the use of dual display screens, which can be used to display two different computer images simultaneously. This may have application for example in CAD computer design application. For these and other purposes it is particularly useful if the two screens or displays can be tilted towards one another so that they appear in the form more or less of two pages of an open book. The screens are preferably arranged side by side, in horizontal alignment, but may also be arranged vertically one above the other.
Referring now to
Each of the screens 10 and 12 comprises a central rectangular display portion 16, and a rectangular marginal frame 18.
The two display screens 10 and 12 are mounted at opposite ends of a mounting arm 20. The mounting arm 20 is itself supported on an upright stand 22 and a base 24. The arm 20 may be connected to the base 22 by a coupling means 26 (
In some cases the manufacturer may simply make the arm permanently attached in one position, i.e. horizontal or the other i.e. vertical, to reduce expense.
As will be noted in
The swingable mounting means 28 and 30 are so constructed as to permit the two screens 10 and 12 to be swung together towards one another, into the configuration shown in
It will be observed that when the arm 20 is fastened in its vertical position as shown in
From the foregoing description it will be understood that it is desirable that the two screens can be swung together into their inwardly angled relation as shown in
For these reasons, the two display screens 10 and 12 are mounted on the arm 20 by means of the swingable mountings 28 and 30. These mountings will now be described in greater detail with regard to
One of the guide members 40A, is wider than the other three guide members 40, to provide guidance when the guide members are assembled in a manner to be described below.
The block 38 and guide members 40 are designed to fit into suitable recesses in the arm 20 (described below).
A collar member 42 of generally semi-arcuate shape, is designed to fit over the block 38 and around the socket 34, for reasons to be described below. Collar 42 is formed with fastening flanges 44 by means of which it may be secured in position as described below.
In this particular embodiment, the arm 20 is provided at each end with three mounting recesses 46A, 46B and 46C. Each mounting recess 46 has four channel shaped grooves 48 formed therein spaced at ninety degrees therearound. The channel shaped grooves 48 are intended to receive the rectangular guide members 40 of the swingable joints.
One of the guide channel grooves 48A is wider than the others, to receive the wider one 40A of the rectangular guide members. In this way the guide members provide a keying function, which controls the positioning of the swingable joints and the display screen.
Bolts 50 align with the blocks 38, and are received in suitable threaded bores 51 (
The ball 32 is provided with a plurality, in this case four screw receiving bores 52, adapted to receive screws 54 therein. The sockets are spaced around the widest part of the ball 32, and are radially spaced apart by 90 degrees from one another. It will be appreciated that while there are four such bores 52, in certain circumstances only two or three screws 54 will be inserted, for reasons to be described below.
The heads of the screws 54 are cylindrical and protrude outwardly from the ball 32, and are received in respective slots 56 formed in socket 34. The ball 32 is a snug frictional fit within the interior of socket 34, so that a significant twisting moment is required to rotate the ball within the socket.
Clearly depending on the number of screws 54 in position, the actual movement of the ball in the socket is restricted. Thus for example if there are three such screws 54 in position, two of the screws 54 will simply limit the movement of the ball 32, so that the ball 32 can virtually be moved only around the axis of the two screws 54. If a third screw 54 is inserted then it will restrict movement of the ball so that it can be rotated only in such a fashion that the screw 54 rides along its respective groove 56, but that it will not be able to move significantly in the reverse angular direction.
For reasons to be described below, two of the slots 56A and 56B are wider and the other two slots 56 are narrower.
The socket 34 has a generally annular base 58, and a spring loaded plate 60 abuts against the annular base 58. The shape of the socket 34 is such that a small cylindrical boss 59 project through a registering opening in the spring plate 60, (FIG. 9).
The spring plate 60 is secured in position by means of screws 62 passing through suitable registering openings 61 on the flange 44 of the collar 42, and secured in threaded openings 63 in plate 60.
By tightening or loosening the screws 62, it is possible to apply greater or lesser pressure by flexing the plate 60 against the rear surface of socket 34, and thus adjust the friction between the surface of the ball 32 in the socket 34. In this way it is possible to preset the rotational force or torque that would be require to rotate the ball in the socket.
Additional control of the friction on the ball is provided by means of the frusto-conical collar 42. This mates with frusto-conical bevels 64 on the exterior of collar 34. Thus by tightening or loosening the screws 50 in the sockets 48, the collar 42 can be made to squeeze and wedge the four sides of the socket 34 together tightly around the ball 32 and thus still further control the friction applied by the socket 34 to the ball 32.
In order to further control and limit the swinging of the ball 32 and stem 36 relative to the socket 34, limiting screws 70—70 are provided, which can be inserted or removed in suitable threaded inserts 72—72 in annular base 58 of socket 34.
One or more such screws 70 can be inserted (
Access to screws 70 can be obtained through registering opening 74 in plate 60.
As mentioned, all of these settings would be preset in the factory before shipment, so that in use the actual scope of movement of the display screen, by means of rotating the ball 32 in the socket 34 is substantially restricted or limited.
It will thus be seen that the novel ball and socket joint described provides a great degree of control on the angular position of the article attached to it, in this case the screens 10 or 12. In fact, by suitable adjustments in the factory, the friction on the ball 32 can be made sufficiently tight that it is substantially impossible to manually move the arm 36 on which the ball 32 is mounted, simply by grasping the block 38.
However, the friction can be so adjusted that by grasping the two edges of the display screen, the position of the display screen can be manually adjusted to the most suitable position, and once adjusted it will remain substantially fixed in that position.
Thus, once the block 38 is inserted in position in its socket in the arm, and locked in position, then by grasping the two side frames of the screen, sufficient torque can be applied, to adjust the position of the screen and rotate the ball 32 in the socket 34 until the screen is in the desired position.
In accordance with various further embodiments of the invention as illustrated in
In this embodiment, for added security, locking screws 90 may be provided in either side of the V-shaped recess 82. The flexibility of the interchangeable screen system according to the invention is further illustrated in
In this way the entire combination of lap-top computer and display 12 can be fitted together and swung down into a closed position for carrying or storage and can be swung upwardly for use, and if desired, the screen 12 as illustrated can be easily removed and a screen having different characteristics or a larger screen can simply be snapped in position, if desired.
The display screen 12 itself can again simply be mounted on an upright arm 112 having at its upper end a generally V-shaped recessed body 114, preferably on a hinged mount 116. The screen 12 will be supplied with a suitable V-shaped locking flange on its rear surface (not shown) of the type already described.
The screen 12 would be connected to a suitable small computer (not shown) again being of the portable type so that it could readily be removed from the vehicle.
A somewhat similar arrangement could be made for the rear compartment of the vehicle illustrated in FIG. 23. In this case a swingable arm 126 is shown mounted in the rear surface of each of the front seats indicated as S in a vehicle.
A suitable V-shaped slotted mounting recess 128 would be mounted on the arm 126. The arm 126 could be swung out from the seat, and a display screen 12 could be mounted on the V-shaped recess.
As illustrated in
The pairs of screens 140 and 142 can be swung open at obtuse angles to one another and stood on a surface such as a table as illustrated in FIG. 29. They may be connected to a computer C by means of daisy chain cables 146, which plug into opposite ends of the tubular hinge bar 144. As in the embodiment of
Various other modifications and adaptations can also be made using the principles of the invention.

The pair of coupling assemblies closely adjacent each other on each support arms 308 and 310 are provided to space two adjacently positioned LCD panels mounted on each arm slightly farther apart from each other to provide additional clearance needed when the two LCD panels are placed in a landscape orientation. Thus, in a landscape orientation, the two LCD panels supported on either of the arms 308 and/or 310 will be supported at the two outermost coupling assemblies 312 near the very ends of each arm. In a portrait orientation the LCD panels will need to be spaced closer to each other, thus requiring one of the LCD panels to be coupled to the more inwardly positioned assembly 312a (
It will be appreciated that the display system 300 could easily be used to support less than four LCD panels 316 if desired. For example, in the drawing of
It will be appreciated that the display system 300 could be easily modified through the use of additional support arms to support more than four LCD panels 316 if needed. For example, the support arm 306 could be lengthened sufficiently to extend above the second arm 308, and a fourth support arm identical to arms 308 and 310 could be coupled perpendicularly thereto such that two extra LCD panels could be supported. An even longer support member and still another extra support arm could be incorporated to support eight LCD panels 316. As can be appreciated, a very large plurality of independent LCD panels can be supported from a single base 302 and support column 304 if needed. Particularly desirable is the feature of being able to orientate the LCD panels 316 in either portrait or landscape mode, or a combination of each, as needed.
Those skilled in the art can now appreciate from the foregoing description that the broad teachings of the present invention can be implemented in a variety of forms. Therefore, while this invention has been described in connection with particular examples thereof, the true scope of the invention should not be so limited since other modifications will become apparent to the skilled practitioner upon a study of the drawings, specification and following claims.
