Claims (5)

  1. A display support arm assembly configured for pivotal movement with respect to an object, the display support arm assembly comprising: a display mounting plate (390); an arm (300) coupled to the display mounting plate (390), the arm (300) having a mounting portion (220) and a body portion; the mounting portion (220) adapted for attachment to the object and having a first washer (226) and a second washer (224A), the first washer (226) being configured to be affixed to the object, and the second washer (224A) being affixed to the mounting portion (220) of the arm; at least one of the first washer (226) and the second washer (224A) defines a groove (225); a third washer (224B) affixed to the second washer (224A) such that the third and second washers (224B, 224A) are adapted to rotate with respect to the first washer (226), wherein the first washer is mounted at a location between the second and third washers (224A, 224B); and at least one gasket (230) disposed between the first washer (226) and the second washer (224A) and at least partly within the groove (225); wherein the at least one gasket (230), the first washer (226), and the second washer (224A) are configured to resist unintended rotational movement of the arm relative to the object; and wherein the at least one gasket (230) is an O-ring and wherein the first washer (226) and the second washer (224A) have dissimilar diameters.
  2. The display support arm assembly of claim 1, wherein the friction produced by the at least one gasket (230) increases in response to an increase in compression of the at least one gasket (230).
  3. The display support arm assembly of claim 1, wherein coupling the first washer (226) to the third washer (224B) produces a predetermined amount of compression of the O-ring.
  4. The display support arm assembly of claim 1, wherein the third washer (224B) has a shoulder portion (229A) and a non-shoulder portion (229B) and upon coupling the first washer (226) to the third washer (224B), the shoulder portion (229A) of the third washer (224B) contacts the second washer (224A) and the non-shoulder portion (229B) of the third washer (224B) is proximal to an inner end section of the first washer (226).
  5. The display support arm assembly of claim 4, wherein there is a clearance defined between the non-shoulder portion (229B) of the first washer (226) and inner end section of the second washer (224A).

Description

FIELD OF THE INVENTION The present invention is directed to display support arm assemblies for mounting an object, for example, a flat screen monitor or the like, in a desired position for easy viewing by a user. BACKGROUND OF THE INVENTION Display supporting apparatuses for supporting flat screen or flat panel displays have been disclosed in the prior art. For example, a display support arm assembly is disclosed in U.S. Patent Publication No 2012/0006767. However, there remains a need for improved display support arm assemblies such as display supporting apparatuses offering the advantages of the present invention, which will become apparent from the description of the invention provided herein and the appended drawings. WO 2014/097122 A1 discloses an ultrasound system control panel and display lift. The control panel and display of a cart-borne ultrasound system are support by a lift which can be controlled to allow the control panel and display to be raised, lowered, and rotated. The lift has a first pivot elbow mounted to the ultrasound system cart and a second pivot elbow on which the control panel and display are mounted. A four-bar linkage is coupled between the pivot elbows which enables to control panel and display to be raised and lowered while maintaining the inclination of the control panel. SUMMARY OF THE INVENTION The invention is defined in the independent claims. Further advantageous embodiments are defined in the dependent claims. BRIEF DESCRIPTION OF THE DRAWINGS The invention is best understood from the following detailed description when read in connection with the accompanying drawings, with like elements having the same reference numerals. When a plurality of similar elements are present, a single reference numeral may be assigned to the plurality of similar elements with a small letter designation referring to specific elements. When referring to the elements collectively or to a non-specific one or more of the elements, the small letter designation may be dropped. This emphasizes that according to common practice, the various features of the drawings are not drawn to scale unless otherwise indicated. On the contrary, the dimensions of the various features may be expanded or reduced for clarity. Included in the drawings are the following figures: FIGS. 1A and 1B are perspective views of an embodiment of a display support arm assembly according to aspects of the invention;FIGS. 2A and 2B are side views of the display support arm assembly of FIG. 1A;FIGS. 3A and 3B are a front view and rear view, respectively, of the display support arm assembly of FIG. 1A;FIGS. 4A and 4B are a top view and a bottom view, respectively, of the display support arm assembly of FIG. 1A;FIG. 5A is a cross-sectional view of the display support arm assembly of FIG. 1A;FIG. 5B is an enlarged view of a section of the mounting portion of the display support arm assembly of FIG. 5A;FIG. 5C is an enlarged view of a section of the upper support arm of display support assembly of FIG. 5A;FIG. 6A is an exploded view of the display support arm assembly of FIG. 1A;FIG. 6B is an enlarged view of a section of the mounting portion of the display support arm assembly of FIG. 6A;FIG. 7A is an enlarged view of a securing mechanism of the display support arm assembly of FIG. 1A;FIG. 7B is an enlarged view of the securing mechanism of FIG. 7A with the cover of the securing mechanism being translucent;FIGS. 8A and 8B are perspective view of a keeper of the display support arm assembly of FIG. 1A;FIGS. 9 is a perspective view of another embodiment of an display support arm assembly according to aspects of the invention;FIGS. 10A and 10B are side views of the display support arm assembly of FIG. 9 in a raised position and a lowered position, respectively;FIGS. 11A and 11B are a side view and a top view of the display support arm assembly of FIG. 9;FIG. 12A and 12B are a rear view and a front view of the display support arm assembly of FIG. 9;FIG. 13 is a cross-sectional view of the display support arm assembly of FIG. 12B;FIG. 14 is an exploded view of the display support arm assembly of FIG. 9; andFIG. 15 is a further embodiment of a display support arm assembly in accordance with aspects of the invention. DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION Aspects of the present invention are directed to display support arm assemblies for mounting a display. The display support arm assemblies may be employed to facilitate a user's ability to rotate, move, or otherwise alter the position of the mounted display to suit the user's desire. It is contemplated that the display support arm assemblies may support objects other than displays, such as medical devices, control devices, input devices, monitors, or any other object. FIGS. 1A - 8B illustrate an embodiment of a display arm assembly (namely, an arm assembly 10) for mounting a display. As a general overview, arm assembly 10 includes a lower support arm 200 and an upper support
