Description

Pivotal Mountinq Bracket Assemblv This invention relates to a pivotal mounting bracket assembly and especially to such an assembly for mounting a satellite dish aerial to a vertical wall or other surface.

According to the present invention there is provided a pivotal mounting bracket assembly comprising first and second members pivoted together about a vertical axis, the first member having a pair of angularly spaced horizontally extending arms for securing said assembly to a vertical surface with said pivotal axis being spaced from said vertical surface, a bracing member extending from the vicinity of said pivotal axis and angularly to said vertical surface for attachment thereto, and a third member horizontally pivotally mounted to said second member and adjustably secured thereto for adjusting the relative angle between said second and third members.

In carrying out the invention the first and second members may be provided with co-operating pairs of generally horizontally disposed vertically spaced support members having a rod therethrough constituting said pivotal axis, it being arranged that the support members of said second member fit between the support members of said first member, a spacer tube being provided between the support members of said second member.

Advantageously, said rod will be constituted by a threaded bolt having a nut which may be rotated to clamp said first and second members together in a required positional relationship.

It may be arranged that said second member is provided with a pair of vertically disposed, horizontally spaced support members between which said third member, which may be of channel cross-section, extends, a first bolt and nut assembly being provided which extends through said horizontally spaced support members and said third member, and which constitutes a horizontal pivot between said second and third members, a second bolt and nut assembly being provided which extends through said horizontally spaced support members and through at least one arcuate slot in said third member whereby the relative angle between said second and third members may be adjusted.

Preferably, the adjustment angle between said second and third members is calibrated, conveniently by providing a graduated scale on said third member and an index point on said second member.

In a preferred arrangement according to the present invention, a pivotal mounting bracket assembly will be provided for supporting a satellite dish aerial, said third member being adapted to have the satellite dish aerial attached to it, and said third member also being adapted to support an outwardly extending arm for carrying a receiver assembly of said satellite dish aerial.

An exemplary embodiment of the invention will now be described reference being made to the accompanying single figure drawing which depicts a pivotal mounting bracket assembly in accordance with the present invention supporting a satellite dish aerial.

In the drawing there is shown a rear view of a satellite dish aerial 1 and tea pivotal mounting bracket assembly 2 by means of which the satellite dish aerial 1 is secured to a vertical wall or other surface (not shown). The bracket assembly 2 also supports an outwardly extending arm 3 which carries the receiver assembly 4 which is located at the focal point of the dish aerial 1.

The pivotal mounting bracket assembly 2 comprises a first member 5 having a central pivot portion 6 from which extends a pair of angularly spaced horizontally extending arms 7, the outer ends of which are provided with flanges 8 having holes by means of which the arms 7 are secured to a vertical wall or other surface (not shown). Preferably, the arms 7 are spaced at an angle of 600 to one another.

The pivot portion 6 of the first member 5 is provided with two horizontally disposed, vertically spaced support members 9, each of which has a hole through both of which extends a threaded bolt 10 which has on its lower end a nut (not shown). The bolt 10 constitutes the pivotal axis of the bracket assembly 2 and supports a second member 11 which is thereby pivotally attached to the first member 5.

The second member 11 includes a central portion 12 which has two horizontally disposed, vertically spaced support members 13, similar to the support members 9 on the first member 5. The support members 13 fit between the support members 9 and have holes therein through which the bolt 10 extends. A tubular spacer 14 is provided between the support members 13 and through which the bolt 10 also extends, so that the bolt 10 and the nut on its lower end can be screwed together to clamp the first member 5 and second member 11 together in a required positional relationship.

The second member 11 is provided with two vertically disposed, horizontally spaced support arms 15 between which is supported-a dish carrier member 16, which is of channel cross-section and the front edges 17 of which are contoured to match to the shape of the dish aerial 1. The dish aerial 1 is attached to the carrier member 16 by means of screwed connectors 18 of known form.

The dish carrier member 16 is pivotally mounted on the second member 11 by means of a bolt and nut assembly 19 which extends horizontally through respective holes in the two members 11 and 16, the bolt and nut assembly 19 constituting a horizontal pivotal axis for the dish carrier member 16 but which when screwed together clamps the dish carrier member 16 to the second member in a required elevational position.

In order to facilitate adjustment to the required elevational position, a second bolt and nut assembly 20 is provided which extends through holes in the dish carrier member 16 and arcuate slots 21 in the support arms 15 of the second member 11. At least one of the support arms 15 is also provided with an index mark 22, preferably formed integrally with it, which, as the dish carrier member 16 is moved relative to the second member 11, traverses a graduated scale 23 formed on the side of the dish carrier member 16. Instructions may therefore be given to preset the adjustment dependent upon the particular location of the satellite dish aerial, and the adjustment may then be finely tuned as required. Once in the required elevational position both of the bolt and nut assemblies 19 and 20 may be screwed together to clamp the dish carrier member 16 to the second member 11.

The lower end 27 of the dish carrier member 16 is provided with a pair of internal clamping members 28 which are secured to it by two bolt and nut assemblies 29, and by means of which the arm 3 is secured to the dish carrier member 16.

In order to further support the weight of the dish aerial 1 a bracing member 24 is provided, one end 25 of which is clamped to the lower end of the first member 5 by means of the bolt and nut assembly 10, and the other end of which is provided with a flange 26 by means of which the bracing member is secured to the vertical wall or other surface (not shown). Preferably, the bracing member will extend at an angle of 450 approximately to the vertical wall.

It should be appreciated that the arms 7 of the first member 1 and/or the bracing member 24 may be provided with strengthening ribs which, for convenience, have not been shown.

The pivotal mounting bracket assembly 2 which has been described enables the satellite dish aerial 1 and the associated arm 3 and receiver assembly 4 to be securely mounted on a vertical wall or other surface, whilst enabling the required elevational and horizontal adjustment of the dish aerial to be carried out.
