Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is the United States National Phase of PCT Patent Application No. GB2014/051736 filed on 5 Jun. 2014, which claims priority to British Patent Application No. 1310116.7 filed 6 Jun. 2013, both of which are incorporated herein by reference. 
     BACKGROUND OF THE INVENTION 
     While the invention has been described with a certain degree of particularity, it is manifest that many changes may be made in the details of construction and the arrangement of components without departing from the spirit and scope of this disclosure. It is understood that the invention is not limited to the embodiments set forth herein for purposes of exemplification, but is limited only by the scope of the attached claims, including the full range of equivalency to which each element thereof is entitled. 
     Antenna Assembly Mounting System 
     The invention to which this application relates is a mounting system for use particularly, although not necessarily exclusively, in the mounting of an antenna to a support surface such as a substantially vertical wall surface. 
     The provision of an antenna to receive broadcast data signals, such as those received by satellite transmission systems, is well known and, typically, at each premises where a subscription has been taken out to receive the satellite signals, an antenna needs to be mounted to an external wall surface; the antenna being required to be directed towards the location from which the signals can be received, such as one or more satellites. Conventionally, the antenna assembly comprises an antenna dish that is mounted on a bracket and an arm is provided on which a low noise block (LNB) is also mounted. The dish and arm are in turn located on a pole that is located on a plate fastened to the wall. 
     Conventionally, at least some of the antenna, arm, pole and plate are required to be assembled on site. For example, with a mid pole mounted antenna assembly, it is often the case that the pole will be fastened to the wall with a bracket or mount for the antenna assembly formed thereon. The antenna assembly is then required to be carried, and the weight of the same supported, at a distance from the ground, by the operator while they attempt to fasten securing means, such as nuts and bolts between the antenna assembly and the bracket or mount on the pole. The antenna assembly has significant weight, which is required to be carried by the installer as they typically move up a ladder to the required height of the location on the wall. Furthermore, the mounting location is at the rear of the antenna assembly, which means that the whole weight of the antenna assembly is therefore required to be supported by the installer in position, as the same is being fitted to the plate or bracket. 
     It has been found that in practice, the need to perform this fixing operation can be difficult to achieve and is physically demanding on the installer, especially when one considers that the installation may be undertaken in environmentally unfriendly conditions, such as in wind and rain. This represents a significant risk to the safety of the installer, both due to the weight of the apparatus and also the particular manner in which the apparatus needs to be supported. Moreover, the height at which the installer is above the surface on the ladder, and also the time constraints which may be imposed for the time of installation, can add further pressure to the installer performing the installation. Other forms of apparatus, such as that shown in GB2310542 require additional components or fixtures to be provided to add further support during the installation procedure, but these additional components add expense to the apparatus as a whole and can themselves be difficult to fit. Furthermore they tend to be o use when the weight of the antenna assembly is not as significant such as when, for example, the antenna assembly does not include a forwardly facing arm or LNB mounted to the front of the antenna dish. 
     It is therefore an aim of the present invention to provide a mounting assembly for use in mounting an article on a surface and, more particularly, to provide a mounting assembly that is particularly useful in the mounting of satellite antenna. 
     In a first aspect of the invention, there is provided a mounting assembly for a satellite antenna assembly including an antenna dish and an arm on which at least one LNB is mounted at a spaced distance from the dish, said mounting assembly including an elongate member for location on a support surface and said mounting assembly includes a first portion provided to be attached to, or integral with the elongate member, and a second portion attachable to or integral with said satellite antenna assembly, and wherein said second portion is moved towards the first portion in a first direction to move at least one part of the first or second portion through an aperture in the other of the first or second portion and subsequent movement of the second portion in a second direction which is substantially parallel with the longitudinal axis of the elongate member brings the first and second portions to a first engagement condition in which the weight of the antenna assembly is borne by the mounting assembly. 
     In one embodiment, said elongate member is a pole with a circular cross section. Typically, the pole is mounted on a support surface such as a wall and the first portion is attached to the pole. 
     In one embodiment the at least one part is provided on the second portion and the aperture is provided on the first portion. In one embodiment at least two parts are provided in a spaced apart configuration on the second portion and preferably are located such that they respectively contact with opposing side walls of the aperture. 
     In one embodiment the aperture includes two slotted regions, said slotted regions spaced apart with a spacing which matches that of the said at least two parts which are received in the slotted regions when in the first engagement condition. 
     In one embodiment each of the parts includes a recess portion which, when the second portion is moved in the second direction locate with the lower edge of the aperture, and most typically with the lower edge of the slotted regions. 
     The engagement of the first and second portions in the first engagement condition by slidably moving the first portion into engagement with the second portion, avoids the need for the use of rotatable engagement means such as nuts and bolts at this stage. This therefore greatly reduces the installation time and, importantly, reduces the time for which the weight of the antenna needs to be supported by the operator during installation. 
     In one embodiment the first portion is attached to the elongate member or provided integrally therewith prior to attaching the elongate member to a support surface such as a wall. 
     In accordance with the invention the installer can carry the antenna assembly and attach it to the first portion of the mounting assembly in a first engagement condition and at which stage the installer is free to take their hands off the antenna assembly, as its weight is supported by the mounting assembly. 
     In one embodiment, the first and second portions can be further secured together into a second engagement condition using engagement means once the first and second portions are in the first engagement condition. 
     In one embodiment, the antenna assembly is attached to, or provided integrally with the second portion prior to engagement of the first and second portions together. 
     In one embodiment, lateral movement in a horizontal plane between the first and second portions is limited once the same are in the first engagement condition. 
     The engagement means ensure that the second portion is mounted in an accurate position with the first portion when engaged thereto. 
     In one embodiment, said engagement means are provided as clamp means. Typically, said clamp means comprise a substantially V- or U-shaped member with threaded free ends and a corresponding pair of nuts, for attachment to said free ends. 
     In one embodiment a first of the V or U shaped engagement means is used to locate and fix the first portion onto the elongate member, prior to movement of the second portion into contact therewith and then a further of the V or U shaped engagement means is provided to pass through the first and second portions of the mounting assembly and the free ends thereof are used to receive nuts which act to hold the mounting assembly in the second engagement condition. 
     Thus first engagement means are used to engage the first portion to the elongate member and second engagement means engage the second portion to the first portion once the second portion has been moved to the first engagement condition. This therefore avoids the need for additional locating and fixing means to be provided which is contrary to the requirements of the prior art apparatus. 
     In one embodiment, said V or U shaped member is placed around the elongate member and the free ends of the clamp means pass through apertures in the first portion and is secured thereto by nuts and the free ends then pass through apertures in the second portion of the mounting assembly. 
     In one embodiment, nuts are attached to the threaded ends of the second engagement means to secure the first and second portions together in the second engagement condition. Thus, the portions are then securely attached to the pole with the nuts tightened to create a substantial friction-fit in the second engagement condition. 
     In a further aspect of the invention, there is provided a method of mounting a satellite antenna assembly including an antenna dish and an arm on which at least one LNB is mounted at a spaced distance from the dish, to a support surface, said method including providing a mounting assembly, said mounting assembly including a first portion, mounting said portion on, or providing the same with, an elongate member, locating said elongate member with the support surface, said mounting assembly including a second portion, mounting said second portion or providing the same with the satellite antenna assembly, wherein moving said second portion in a first direction to move at least one part of the first or second portion through an aperture in the other of the first or second portion and then moving the second portion in a second direction substantially parallel with the longitudinal axis of the elongate member moves the mounting assembly portions to a first engagement condition in which the weight of the satellite antenna assembly is borne by the mounting assembly, elongate member and support surface. 
     In one embodiment said movement is to move the said second mounting portion, with the antenna attached thereto into position with the first portion in a sliding action. Typically the second movement direction is downwardly so as to hook and locate the second mounting portion with the first mounting portion. 
     In one embodiment once the said first engagement condition has been achieved, engagement means are installed that allow said first and second mounting portions to be brought to a second engagement condition and at which condition the mounting is complete. 
     In one embodiment the first direction of movement is substantially perpendicular to the longitudinal axis of the elongate member. 
     Specific embodiments of the invention are now described with reference to the accompanying drawings, wherein: 
       FIGS. 1   a - b  illustrate an embodiment of the present invention being mounted on a support means and subsequently mounted on the support means. 
       FIGS. 2   a - b  illustrate a first mounting portion according to an embodiment of the present invention and associated parts, individually and subsequently mounted to a support means. 
       FIG. 3  illustrates a second mounting portion according to an embodiment of the present invention; and 
       FIG. 4  illustrates the satellite antenna assembly mounted using the mounting assembly of the invention 
    
    
     Referring firstly to  FIGS. 1   a - b , there is provided a mounting assembly ( 2 ) for mounting an antenna assembly to a support surface in the form of a wall of a building and/or the like. The mounting assembly ( 2 ) includes a first mounting portion ( 4 ) provided to be attached to, or provided integrally with, a elongate member support means in the form of a pole ( 6 ). The pole ( 6 ) can already be attached to a wall of a building, or be subsequently attached after the first mounting portion ( 4 ) is fixed thereto. The mounting assembly includes a second portion ( 8 ) which is attached to, or provided integrally with, a satellite antenna assembly, which is to be supported in position by the mounting assembly ( 2 ). Further housing ( 10 ) is provided which can be conventional in form for the antenna assembly in order that the antenna is retained securely in place and can be positionally adjustable when attached to the support surface. The mounting assembly further includes, in this particular embodiment, first and second engagement means in the form of V- or U-shaped members ( 12 ,  12 ′), and associated nuts ( 14 ,  14 ′). 
     This is shown more clearly in  FIGS. 2   a - b , wherein the clamping means ( 12 ) are used to mount the first mounting assembly portion ( 4 ) to the pole ( 6 ) and be secured in position by means of nuts  14 . Typically, although not shown the nuts  14  are recessed such that the surface  38  of the portion  4  is substantially flat. 
     The satellite antenna assembly  21  to be held in position by the mounting assembly ( 2 ) typically includes an antenna dish  20 , a low noise block (LNB) 22 , and an arm  24  which serves to locate the LNB  22  at the required distance  26  from the front of the dish  20 , as shown in  FIG. 4  where the assembly is shown as being mounted in position on the pole using the mounting assembly of the invention. 
     The mounting assembly ( 2 ) provides a novel and effective means for mounting a satellite antenna assembly to a wall  25  of a building and one which allows the antenna assembly to be installed with a significantly reduced requirement for the installer to support the weight of the antenna assembly during installation. 
     In the installation of the antenna assembly, according to one embodiment, the installer attaches the first portion  4  of the mounting assembly to the pole  6  at the required location thereon. The first portion  6  is retained in that position by placing the clamp means  12  through the apertures  28  in the first portion shown in  FIG. 2   a  and then engaging the nuts  14  in position as shown in  FIG. 2   b . With this having been performed, the pole  6  is attached at the required height to a support surface such as a wall prior to attachment of the antenna assembly ( 2 ). It should be appreciated that in another embodiment the pole  6  may be attached to the support surface and then the first mounting assembly portion  4  is attached to the pole  6  at the required height and using the same engagement means  12  as described. This can relatively easily be achieved as the first mounting assembly portion  4  has no significant weight to be supported during installation. 
     Once the pole ( 6 ) is attached to the wall the installer can carry the antenna assembly, with the second mounting portion  8  already provided therewith, to the height of the first portion  6  on the pole  6  and as shown at  FIG. 1   a . The installer can then move the antenna assembly  21  and the second portion  8  of the mounting bracket in the direction  30  indicated in  FIG. 1  a so as to move the second portion  8  such that the parts  13  in the form of spaced apart plates, move into and through the aperture  15  in the first mounting portion. In this embodiment, slotted regions  17  are provided as part of the aperture to thereby locate the parts  13  of the second mounting portion therewith and retain the same in the position at the respective opposing side edges of the aperture. The parts  13  are each provided with recesses  40  as illustrated in  FIG. 3  and as also shown in  FIG. 1   a . Once the second portion has been moved in the direction  30  to a point at which the first and second portions  4 , 8  are in contact or at least adjacent thereto, the second portion  8  and hence antenna assembly  21  mounted thereon are moved in the direction of arrow  42  which is substantially parallel with the longitudinal axis  44  of the pole  6 . This movement causes the recess portions  40  of the parts  13  to receive the respective bottom edges of the slotted regions  17  of the aperture  15  therein and act as hook members to thereby lock the first and second portions  4 , 8  of the mounting assembly together in the first engagement condition. This therefore allows the weight of the antenna assembly  21  to be supported by the first mounting portion and the pole  6  and so the installer is then free to take his hands off the antenna assembly to further engage the same in position and also to perform adjustment of the azimuth and or elevation of the dish  20 . Typically the first portion  4  has engagement formations  52 , of the type shown in  FIG. 2   b , to aid in the engagement of the first portion  4  with the pole  6 . In one embodiment the second portion includes a further part in the form of lip  50  as shown in  FIG. 3  which also passes into the aperture  15  in the first portion as shown in  FIG. 1   b  and engages the top edge of the aperture to further aid the formation of the first and second portions of the mounting assembly in the first engagement condition. 
     To form the second engagement condition, once the second mounting portion ( 8 ), which is shown in more detail in  FIG. 3 , is attached to the first mounting portion ( 4 ) as described above, the V or U shaped clamp  12 ′ can be positioned as shown in broken lines in  FIG. 1   b  with the free ends of the same passing through the apertures  46  in the first portion and apertures  48  in the second portion  8 . The free ends then receive the nuts ( 14 ′) thereon which serve to secure the clamp  12 ′ and hence the first portion  4 , pole  6  and second portion  8  in position. 
     The movement in direction  42  between the first ( 4 ) and second ( 8 ) mounting portions, to provide the first engagement condition, as shown in the figures, is provided in a substantially vertical plane. Typically, substantially all lateral movement in a horizontal plane between the first ( 4 ) and second ( 8 ) mounting plates is limited by the engagement of the V or U shaped member ( 12 ) and nuts ( 14 ), and is eliminated when the second engagement means  12 ′,  14 ′; are located for the second engagement condition to be achieved. 
     This then allows the subsequent azimuth and elevation adjustment of the antenna dish  20  with respect to the mounting assembly to be achieved using conventional adjustment means  38 . 
     The present invention therefore provides an efficient way in which to allow for the installation of a satellite antenna assembly at a raised position and to allow the weight of the assembly to be supported by the mounting assembly in a first engagement condition and thereby allow a second engagement condition to be achieved.
