A display bracket with tilt adjustment is disclosed which allows the installer to mount the bracket to a surface and place the display holding section in a cradle like structure without fear that it will fall. The display holding section can then be affixed to the display bracket and adjustment to the tilt angle can be made without the installer having to bear any of the display weight. Final horizontal leveling can be accomplished with set screws.

The present application claims the benefit of U.S. Provisional Application Ser. No. 60/857738 filed on 8 Nov. 2006, the complete subject matter of which is hereby incorporated herein by reference in its entirety.
This disclosure is directed to brackets for mounting devices to a fixed location, most commonly for mounting a flat panel display screen, or other device to a wall, with the ability to move the screen into various positions for viewing and storage.
With the advent of flat panel video screens such as plasma video screens, there is a need for efficient and flexible mounting of such screens or other devices against a wall or other fixed surface. It is highly desirable to move such screens from a position adjacent a mounting surface to a position closer to the user and this may entail a mount which can articulate in many directions.
As displays become heavier and/or larger they exert greater torque on the mounting bracket. This makes articulation more complex and there is a tendency for the mass of the display to focus forces on a small number of moveable parts causing considerable stress.
It would be advantageous to provide a highly rigid structure which allows the display to be moved away from the mounting surface and further have the ability to tilt off the vertical axis to allow viewing at many angles. All of this has to be accomplished under great stress of a heavy display distant from the wall.
A tiltable mounting bracket system 10 is shown most clearly in
Display 12 is an exemplary flat panel display which is affixed to the bracket system 10 by a plurality in this case, two universal brackets 14 which are in turn carried by universal bracket bar 18. In this case, the two brackets 14 are indicated although the system could be made to function with a single or more than two such brackets. The brackets are affixed to the display by means of fasteners (not shown). Brackets 14 are affixed to universal bar 18 in a number of ways. In the preferred embodiment, brackets 14 include aperture 16 which permit universal bar 18 to slide therethrough and then be affixed into place by fasteners through an aperture 20 (see
Bar 18 is then joined to the rest of bracket system 10 by a tilting assembly 22. This assembly 22 will be described in much greater detail below, but suffice it to say, it allows for the display and consequently, brackets 14 to be tilted off the vertical axis. It also provides for the display orientation to remain substantially horizontal and not skewed. Skewing can occur due to weight imbalances, wall mounting errors, manufacturing tolerances, etc. The larger the display screen, the more prominent these problems can be come. The rear portion of tilting assembly 22 is then attached to a cross member 30 by means of a vertically oriented pivot system 32.
Cross member 30 pivots on a vertical member 32 which joins two parallel bars 34 and 36 which themselves are joined by a cross member 38.
Thus the system can be left or right handed much as a door can be left or right handed to allow it to swing from the left or the right depending on the user's preferences. This is accomplished by attaching the bracket arrangement which includes display 12 from the right side or the left side of the pivots on mounting bars 40 and 42.
A sub-frame assembly 61 is thereby created with bars 40, 42, 38 and 60 and this sub-frame is then attached to a wall or other mounting surface.
Many of the bars include apertures 70 which have pliable covers 72 (see
In the side view of
Recess 94 is to provide clearance for the heads of fasteners which pass through apertures 96 to join the remaining tilting assembly without interference with the sliding movement.
To assist in the sliding movement, a low resistance interface plate 110 is provided to sit within an additional recess/channel (to control movement and to countersink attachment bolts) and to preferably fill the entire recess space with a low friction material. A nylon, Teflon®, polypropylene, or other no friction material may be used. In addition, it is helpful if the concave surface of plate 110 is lubricated with a silicone or other suitable lubricant.
Turning to FIGS. 7and 9, the tilting assembly 22 can be seen to have a number of elements (some of which are optional) forming the entire assembly. Nosepiece 80 includes a recess which receives low friction interface plate 110 which in turn receives saddle bracket 120, having sidewalls 121 which form a protrusion sized to be received within channel 90, in a nested relationship. This nested relationship or fit, is defined as a close fit, sufficient to prevent substantial torquing or turning of one bracket relative to the other, but not so tight as to prevent movement therebetween (i.e. one fits within the other such that they will track a co-linear substantially parallel path). In practical terms, some “play” between the brackets is not objectionable, because, in practice, the two brackets will be bolted together to prevent further twisting and sliding movements. Saddle bracket 120 also has a recess 122 for receiving an optional second low friction interface plate 130, which finally receives a saddle cover plate 140. A affixation means such as a flange 150 extends from bar 18 (preferably welded/attached to the bar) and is ultimately connected to saddle bracket 120 when fully assembled. Saddle bracket 120 includes an elongated slot 123 located preferably centrally within the recess 122. The extent of the slot 123 determines the degree of angular or arcuate movement permitted by virtue of a bolt or pin extending therethrough. In the preferred embodiment this slot extends from the upper end of the recess to the lower end, though it may be limited to control the titling angle and the center of gravity of the entire system. In a very large display, it may be undesireable to allow angles beyond 30 degrees, however, the angle could be as great as 90 degrees so that a ceiling mount could project horizontally for normal viewing.
Saddle bracket 120, as shown in
Saddle bracket 120 is designed to cradle bar 18, preferably so that the bar can simply be placed into the bracket by the installer and it will remain in place while further installation is completed. This is accomplished by mating the shape of the saddle bracket to approximate the bar shape, preferably with its center of gravity (of bar 18 and the display) being within the saddle bracket. Bracket 120 includes a pair of cradle-like receiving portions 204 (in the preferred embodiment, being hooked-shaped ) which are designed to receive and cradle bar 18. The shape of hooks 204 should be configured to mate with bar 18. In this case the arbitrary shape is oval. It can also be appreciated that the receiving walls having a curved portion 206 of bracket 120 is likewise formed to receive whatever shape bar 18 may have. If the saddle bracket is configured to maintain the center of gravity of bar 18 and its associated display components, within saddle bracket 120, then the display portion of the system can rest in the “cradle” in equilibrium while the installer can complete installation by locking saddle bracket and bar 18 together with a fastener or other means. This is accomplished by forming curved portion 206 (the receiving recess in saddle bracket 120 such that the center of gravity of then display bracket it receives will be inside of hooks 204). Inside means between the hooks and the recess bounded by curved portion 206. As a result the display will “lean” into curves 206 and stay in place even if not otherwise secured by bolts, etc. This frees the installer from needing immediately bolt the display bracket into place, since it will rest safely.
Saddle bracket 120 includes a recessed area 122 (as mentioned above) which permits it to receive the second low friction interface plate 130 and the second saddle cover plate 140 which are together bolted by bolts 240 (one shown in
During assembly, bolt 240 is prevented from counter rotating by interlocking of the bolt head/shaft with apertures 250 and thus tightening of nut 242 will cause the entire tilting assembly to be fixed in its angular position. Thus, the user will select the appropriate tilt and then tighten nuts 242.
Of course it can be appreciated the different kinds of fasteners could be supplied such as wing nuts and bolts and other devices which make for easy user adjustment of the tilt angle.
The tilting assembly 22 therefore carries bar 18, brackets 14, and thus display 12 to ensure that the display is securely affixed to the rest of the system. Flange 150 with its aperture 122 are bolted to saddle bracket 120 with a fastener. Bar 18 sits within curve portion 206 creating a snug fit from top to bottom. Level adjustment bolts 280 pass through arms 282 on either side of saddle number 122 and provide for a fine tuning level adjustment for the display. There may be numerous causes for bar 18 to be inherently skewed (i.e. off horizontal alignment) such as an incorrect leveling of the mount on the wall, slight errors in various components the mount, errors in the mounting holes of the display, etc. Level adjustment bolts 280 allow for this skew to be corrected with ease. (See
In operation, bolt and nuts 242 , which together form a locking device or lock, are left loose enough to allow saddle bracket 122 to slide freely within nose bracket 80 in slot 123 (
Once the user has selected the proper viewing angle for display 12, bolts 240 and nuts 242 are tightened down so that rotational titling movement is inhibited. To remove any skew in the display with respect to the horizontal plane, bolts 280 are adjusted appropriately preferably using a level atop the display. The display can also be shifted laterally (horizontally), that is, side to side, by sliding bar 18 within apertures 16 of brackets 14. This should be limited to prevent undue weight imbalances in the entire system.
Thus it can be seen that the display 12 can be removed from the tilting assembly 22 by removing the locking bolt which passes through aperture 152 of flange 150 and if necessary, loosening leveling bolts 280. Thus, it is appreciated that the remaining mounting structure is undisturbed and a replacement display, for example, can be installed with great ease.
The method of operation is therefore, that the display 12 is attached to bars 14 which in turn receives bar 18. This assembly can be completed separately from the rest of the mount and this adds greatly to its ease of use. Trying to attach a display to a suspended wall mount is relatively difficult due to its weight and fragility. With the present invention this problem is completely eliminated.
The remaining portion of the wall mount is assembled, for either left or right orientation (see above) and then it is affixed to a wall (or equivalent). The two portions are then bought together by merely placing bar 18 into the saddle bracket, inserting the locking fastener and adjusting the leveling bolts. Thus this two part mount makes installation and replacement of the display unit much simpler and safer than unitary designs.
