Description
TECHNICAL FIELD

This disclosure relates to tiling stand for use with medical apparatus and more particularly to systems and methods for changing the angle of presentation of medical data using a medical device display screen.


BACKGROUND OF THE INVENTION

Electronic devices are now commonplace and are used in many situations. For example, in the medical field some devices, such as sonogram monitors are now portable and have display screens for monitoring of the procedure. When the operator is standing the display need to have one slope angle and when the operator is sitting the angle needs to be changed to accommodate the differing viewing heights.


In addition, adjustments need to be made depending upon the height of the surface upon which the device is positioned. These adjustments in slope angle must be made quickly and easily and must not add bulk or weight to the portable device. A further requirement is that the positioning device, while necessarily light in weight and bulk, must also be able to withstand the rigors imposed by certain embodiments, such as hospitals, battle fields and disaster scenes.


BRIEF SUMMARY OF THE INVENTION

The viewing angle of a display is controlled by a stand which is selectively lengthened. In one embodiment, at least one cascaded tubes are employed to allow for elongation of the stand. The stand, in one embodiment, can be rotated against the body of the device thereby creating a relatively shallow display slope angle. In a further embodiment, a plurality of cascaded tubes are disposed parallel of each other.


The foregoing has outlined rather broadly the features and technical advantages of the present invention in order that the detailed description of the invention that follows may be better understood. Additional features and advantages of the invention will be described hereinafter which form the subject of the claims of the invention.

BRIEF DESCRIPTION OF THE DRAWINGS

For a more complete understanding of the present invention, reference is now made to the following descriptions taken in conjunction with the accompanying drawing, in which:



FIG. 1 shows one embodiment of a side view of a display having a slope created by a stand in accordance with one aspect of the invention;



FIG. 2 illustrates a user preparing to elongate the stand of FIG. 1;



FIG. 3 shows one embodiment of the stand in one elongated position; and



FIG. 4 shows the display having a slope created by the stand being rotated flat against a back surface of the display.





DETAILED DESCRIPTION OF THE INVENTION


FIG. 1 shows one embodiment 10 of a side view of display 101 having a slope (e1) created by stand 100 in accordance with one aspect of the invention. Device 101 has display 102 which is sloped with respect to surface 120. The slope of the display can, as will be discussed, adjusted so that a user of device 101 can have a clear view of the display and other controls. In one embodiment, device 101 is a medical device, such as, for example, a sonogram monitor.


Stand 100 can be elongated along its longitudinal axis from a length of d to a length of d′ as shown in FIG. 3. Stand 100 can also be rotated so that it folds against back surface 103 of device 101. One embodiment to accomplish such rotation is shown where pin (or other fastening device) 23 is positioned through a hole in portion 130 of stand 100, through a hole in bracket 22 and into portion 140 of stand 100. Bracket 22 is secured to rear surface 103 of device 100, for example, by a fastener, such as fastener 202. Rear surface is essentially parallel to display surface 102. Bottom portion 104 of device 101 can be positioned on surface 120 to form a line of support for device 101.


Stand 100, in the embodiment shown, has two support portions 11 and 12. Support portion 11 is adapted to pivotally mate with bracket 22 (as discussed above) at its proximal end. Support portion 12 is adapted at distal end 105 to mate with a surface, such as surface 105, upon which device 101 is positioned so as to form a second contact point. In conjunction with bottom portion 104, length d of stand 100 creates a particular slope with respect to surface 120.



FIG. 2 illustrates a user preparing to elongate stand 100 by gripping support portion 12, perhaps with the assist of protrusions 24, and pulling portion 12 toward its distal end and away from support portion 11 which is affixed to the rear surface of device 101.



FIG. 3 shows one embodiment of stand 100 with support portion 12 pulled outward (away from display 101) thereby increasing the length of stand 100 to length d′. This in turn then changes the slope of display 102 to e2. In the embodiment shown, portions 11 and 12 are connected together by at least two parallel elongating portions 31. The elongating portions, as shown, have a plurality of nesting (cascading) tubes 31a, 31b, 31c, 31d, 31e that are connected at distal end 31e to support 12 and at proximal end 31a to support 11. This connection is, in one embodiment, relatively permanent and can be accomplished in any one of a number of ways, such as, for example, gluing or pinning. The cascading sections each slide inside a next larger tube and the total length can be a designer's choice. The tube sections are constructed in the well known manner so that they do not come all of the way out of the next larger tube. Note also that one or more stops can be created so that the elongation length of stand 100 (and thus the slope of display 102) can be controlled as desired.


Distal end 301 of support 11 is adapted to physically mate with proximal end 302 of support 12. Any type of mating relationship will work.



FIG. 4 shows the slope of device 102 reduced to angle ø3 by rotating stand 100 up against rear surface 103 of device 101. In this configuration, ridges 24 mate with surface 105 to form the desired slope.
