TECHNICAL FIELD
The present invention relates to await mount arm for holding television or computer screens and more particularly wherein the screen can be a non-flat screen.
In recent years the classic cathode ray tube (CRT) computer and television screens have generally been replaced by thin screens based on liquid crystal display (LCD) or light emitting diode (LED) technology. Additionally the standard available screen size has increased. Instead of a maximum size of 32″ or less a person can purchase television screens with a screen size of 40″, 50″ or even 80″-90″.
The newer screens are much lighter than the older CRT screens and can conveniently be hung from a wall with a mechanism having an arm and a mounting interface at the screen end designed to fit standard screw holes on the back of the screen.
The Video Electronics Standard Association (VESA) defined a family of standards know as the Flat Display Mounting Interface (FDMI) or VESA Mounting Interface Standard (MIS) defining the mounting interface size and distances between the screw holes on the mounting interface and on the back of the screen as a function of the screen size (diagonal) and weight.
Recently curved screens (e.g. concave screens) have been introduced and they are gaining popularity since many viewers feel that they provide an enhanced viewing experience. One problem with curved screens is that the screw holes are shifted so standard wall mount interfaces don't fit. Thus a consumer is limited to using more expensive dedicated mounting interfaces or to add non-standard inserts, spacers or special screws for attaching a standard mounting interface. In many cases non-standard additions can result in an unstable wall mount. Accordingly a solution that fits flat screens and non-flat screens is thus desirable.
An aspect of an embodiment of the disclosure relates to a system and method for mounting a flat or curved screen to a wall. The mounting is performed using a mounting interface that is attached on one side to the back of the screen and on the other side to the rest of the mounting system. The mounting interface can be a polygonal mounting interface having semi-spherical depressions near the vertices or it may have any other shape with depressions near the edges. Additionally, the interface has multiple elongated beams with matching semi-spherical depressions to be coupled to the mounting interface in a ball and socket manner. The elongated beams can be tilted up and down (out the plane of the mounting interface) and/or moved right or left (in the plane of the interface) while the matching semi-spherical depressions are in contact with each other. During installation the elongated beams are adjusted so that cut out portions on the elongated beams enable the elongated beams to be attached to the back of the screen, for example by inserting a screw through the cut out portion into a screw socket on the back of the screen. Once the elongated beams are adjusted the matching semi-spherical depressions are locked together so that the mounting interface forms a rigid unit with the elongated beams and can be easily attached to the back of the screen.
In some embodiments of the disclosure, the depressions can be located anywhere on the mounting interface and not specifically near the edges. Optionally, more than one elongated beam can be places within a single depression on the mounting interface.
Optionally, the matching semi-spherical depressions are locked together using a screw and nut. The nut may be spherical or semi-spherical to fit better into the depressions. In an exemplary embodiment of the disclosure, the semi-spherical depression on the elongated beam is placed inside the semi-spherical depression of the mounting interface. Alternatively, the semi-spherical depression on the elongated beam is placed outside the semi-spherical depression of the mounting interface. Optionally, both of the semi-spherical depressions have a hole for inserting a screw and nut to lock them together and prevent them from moving once they are adjusted as needed. In an exemplary embodiment of the disclosure, the hole on the elongated beam is larger than the hole on the mounting interface or vice versa to enhance the ability to adjust the position of the elongated beam relative to the mounting interface.
There is thus provided according to an exemplary embodiment of the disclosure, a wall mounting system for connecting a back of a flat or curved screen to a wall, comprising:
A mounting interface having semi-spherical depressions;
Multiple elongated beams having matching semi-spherical depressions for adjustably coupling with the semi-spherical depressions of the mounting interface; wherein the semi-spherical depressions of the elongated beams and the mounting interface have holes for non-movably coupling between them once adjusted;
Wherein each elongated beam has one or more cut out portions for attaching the elongated beam to the back of the screen; and
Wherein the mounting interface serves as an interface for holding the screen while it is attached to the wall by the mounting system.
In an exemplary embodiment of the disclosure, the mounting interface has a polygonal shape. Optionally, the semi spherical depressions of the mounting interface are located near the vertices of the polygonal shape. In an exemplary embodiment of the disclosure, the mounting interface is shaped as a square or rectangular. Optionally, the mounting interface includes a central part and extensions that are detachable from the central part; wherein the semi-spherical depressions are located on the extensions. In an exemplary embodiment of the disclosure, the hole in the semi-spherical depression on the elongated beam is larger or smaller than the hole in the semi spherical depression of the mounting interface to enable positioning the elongated beam to fit a curved screen. Optionally, the semi-spherical depression on the elongated beam is coupled to the semi-spherical depression of the mounting interface using a screw and nut. In an exemplary embodiment of the disclosure, the elongated beam is attached to the screen by inserting a screw through the cut out portion into a screw socket on the back of the screen. Optionally, the mounting interface is attached to the wall with a tilting mechanism to enable the screen to tilt up and down. In an exemplary embodiment of the disclosure, the mounting interface is attached to the wall with multiple stages that are pivotally connected.
There is further provided according to an exemplary embodiment of the disclosure, a method of connecting a back of a flat or curved screen to a wall with a mounting system, comprising:
Providing a mounting interface having semi-spherical depressions;
Placing multiple elongated beams having matching semi-spherical depressions into the semi-spherical depressions of the mounting interface;
Adjusting the elongated beam relative to the screen and the mounting interface;
Coupling between the semi-spherical depressions of the elongated beams and the semi-spherical depressions of the mounting interface by a hole in the semi-spherical depressions of the elongated beams and a hole in the semi-spherical depressions of the mounting interface;
Attaching between a cut out portion on each of the elongated beams with the back of the screen; and
Connecting the mounting interface to the wall.

In some embodiments of the disclosure, the mounting interface 110 can have any shape and the depressions 130 may be positioned anywhere on the surface of the mounting interface 110.
In an exemplary embodiment of the disclosure, the semi spherical depressions 122 of the elongated beams 120 are positioned inside the semi spherical depressions 130 of the mounting interface 110 and they are coupled together after adjusting the elongated beams 120 so that cut out portions 140 on the elongated beams 120 match screw sockets 150 on the back of the screen 100 (see
The elongated beams 120 can be rotated right or left in the plane of the mounting interface 110 or up or down relative to mounting interface 110 (e.g. out of the plane of mounting interface 110). Then once the elongated beams 120 are positioned to match the screw sockets 150 on the back of the screen 100, the elongated beams 120 and the mounting interface 110 are locked together, for example using a screw 160 and nut 165 or other locking means (e.g. a dowel pin). Optionally, semi-spherical depression 122 includes an enlarged screw hole 124 (larger than a screw hole 134 of the semi-spherical depressions on the mounting, interface 110) to allow the elongated beam 120 to be adjusted freely relative to the mounting interface 110. Alternatively the screw hole 134 of the semi-spherical depressions 130 on the mounting interface 110 may be larger. In an exemplary embodiment of the disclosure, the nut 165 is also shaped to be semi-spherical or spherical to enhance locking the mounting interface 110 to the elongated beam 120. In some embodiments of the disclosure, nut 165 may be a standard circular nut or standard hexagonal nut. Optionally, the nut 165 is enclosed in a housing 167 (e.g. a plastic housing) providing it with a spherical shape so that it will fit better into semi-spherical depression 122 and/or semi-spherical depression 130 to prevent movement once the elongated beams 120 are positioned correctly.
In an exemplary embodiment of the disclosure, the mounting interface 110 with the elongated beams 120 locked to it is attached to the back of screen 100 with locking screws 155. Optionally, the mounting interface 110 and the elongated beams 120 are made from rigid materials, for example metals such as aluminum or steel. In some embodiments of the disclosure, rigid plastic materials are used depending on the strength of the material and the weight of the screen. In sonic embodiments of the disclosure, the mounting interface 110 with elongated beams 120 can be used also for standard flat screens by adjusting the elongated beams 120 and not only for curved screens (e.g. concave screens).
In an exemplary embodiment of the disclosure, a tilting mechanism 340 may be coupled to the back of mounting interface 110 to enable the screen to tilt up and down relative to the extension arms (310, 320). Optionally, the tilting mechanism 340 is connected with a pivot 325 to extension arm 320 so that the tilting mechanism 340 can swivel relative to extension arm 320.
It should be noted that mounting interface 110 with elongated beams 120 can be attached to other types of wall mount systems, including more stages or less stages, providing tilting, swiveling and/or rotation with more degrees of freedom or less than exemplified by wall mount system 300.
In an exemplary embodiment of the disclosure, wall mount system 300 includes a cable guide 350 for gathering and guiding cables that connect between the screen and other devices, for example speakers, electrical outlets, computers, receivers, converters, video/DVD players and other equipment. Optionally, wall mount system 300 may include a shelf (not shown) for placing such equipment near the screen.
