wherein the slot is elongated such that it enables adjustment of the relative positioning of the first and second components while said first and second components are secured together by the at least one screw of the locking device.
At the free longitudinal side of the flange 10 c, at respective positions aligned with the respective bosses 14, 15 are integral downwardly depending hooks 20, 21, each hook being of generally rectangular form and being at 90° to the flange 10 c, so as to lie parallel to the front part 10 a of the front plate 10. The depth of each hook is, in this example, slightly less than the width of the flange 10 c.
At the centre of the lower flange 10 d there is a circular opening 22 over which at the outer surface of the flange 10 d is a circular boss 23 which, like the bosses 14 and 15 has an internally threaded circular opening 24 therethrough, this opening being co-axial with the larger diameter opening 22 in the flange 10 d. Accordingly as for the bosses 14, 15, the boss 23 can receive a screw 25, for a purpose to be referred to hereinafter.
The wall plate 11 is of similar form to the front plate 10, having a flat front part 11 a from which extends at the-same side thereform, at right angles thereto, respective upper and lower flanges 11 b and 11 c. A pair of longitudinally spaced apart rectangular slots 27, 28, are formed at the upper end of the part 11 a, each slot commencing substantially at the junction between the front part 11 a and the upper flange 11 b, and extending a short way down into the front part 11 a, as best shown in FIGS. 7 and 8. These slots are to receive the hooks 20, 21 respectively, but are oversized relatively thereto, so that there is a clearance at the respective opposite sides of each hook from its associated slot, and additionally there may be a clearance at the longitudinal free end of each hook even when the wall plate 11 is at its uppermost position in the front plate 10 as will be described. To this end it should be noted that, as shown in FIG. 1, the wall plate 11 is proportionately smaller than the front plate 10 so that, as shown in that Figure, it can be substantially received therein with its upper flange 11 b below the flange 10 c and its lower flange 11 c above the flange 10 d.
An elongated slot 29 is provided in the lower flange 11 c midway between its ends, the positioning of this slot being such that, when the front plate and the wall plate are assembled together as shown in FIG. 1, the shank of the screw 25, when the screw is tightened, will extend into this slot 29 and thereby prevent the front plate and the wall plate swinging apart. Finally with regard to the wall plate 11, it will be noted that it is provided with three generally vertically spaced fixing openings 30 generally centrally in its front part 11 a, these openings 30 being to allow the plate 11 to be fixed to a wall or equivalent surface.
From the description above, it will be understood that with all the screws 18, 19 and 25 unscrewed to their respective outermost positions engaged in their respective bosses, it is possible to engage together the front plate 10 with the wall plate 11 by presenting the front plate 10 substantially at 90° to the wall plate 11 and manipulating it so that the hooks 20, 21 are received in the respective slots 27, 28 of the wall plate 11 and then swinging the front plate 10 in a pivoting motion to the position shown in FIG. 1 where the front part 10 a of the front plate 10 is substantially parallel to the front part 11 a of the wall plate 11. Before the pivoting takes place, the wall plate 11 is secured to a wall or equivalent surface so that it is vertical. When a television or other flat panel is then secured to the front plate 10 using the fixing openings 26, the weight of the panel/television will bring the front plate 10 vertically downwards so that the underside of its upper flange 10 c will bear on the upper surface of the upper flange 11 b of the wall plate 11, given that the screws 18 and 19 do not project beyond the lower surface of the flange 10 c.
If, in the position now described, the panel or television is correctly mounted, i.e. with its upper longitudinal surface horizontal, then no adjustment of the mount is required. However if the upper surface of the panel or television is not horizontal, it is possible to adjust the mount so that this surface becomes horizontal. This adjustment is by way of adjusting one of the screws 18 and 19, so as, in a sense, to tilt the front plate 10 relative to the fixed wall plate 11 in a vertical plane so that the upper surface of the object mounted moves to become horizontal. It will be understood that the free end of the shank of the screw 18 or 19 which is adjusted bears against the upper surface of the flange 11 b of the wall plate so as effectively to ‘push’ the front plate upwards and it can be seen that this produces a slight pivoting movement about the point of engagement of the shank of the other screw on the flange 11 b. During this adjustment the screw 25 will have been tightened so that its shank is received in the elongated slot 29, and the elongation of that slot enables the tilting/adjustment movement described to take place, in that it allows for the pivoting of the front plate relative to the wall plate even though they are secured together against pivoting about the hooks 20, 21 and slots 27, 28 by virtue of the screw 25 which effectively locks the two plates together. The tilting adjustment provided by screws 18, 19 depending upon which way the tilt is to be adjusted, is facilitated by the relatively loose fit of the hooks 20, 21 in the oversized slots 27, 28.
Although the example shown in provided with a single slot 29 and screw 25 coupling between the front plate 10 and the back plate 11, multiple slots with respective screws may be employed. Thus, slots may be provided at intervals along the length or width of flange 11 c.
In a still further embodiment, the lower flange 11 c of the wall plate could be provided with a forwards extension, either as a separate part or integrally, to provide one or more further slots 29 forwardly of the slot 29 shown so that the two plates 10 and 11 could be locked together with the parts 10 a and 11 a at an angle to one another rather than being parallel as shown in FIG. 1, i.e. with the front plate tilted relatively to the wall plate 11 so as to incline the panel or screen carried by the front plate 10.
In the still further embodiment of the mount shown in FIG. 16, the front plate 110 and wall plate 111 are of the form shown in FIGS. 12 to 15. However with this embodiment a pair of spaced parallel mild steel adaptor plates 131 are secured by screws to the outwardly facing surface of the front part 110 a of the front plate 110 in order to provide fixing openings for a larger panel or screen, each adaptor plate being secured to the front plate 110 by suitable fixings 130 in the openings in the logo 110 b.
FIGS. 17 through 20 show a yet further embodiment of a mount according to the present invention. Since some of the component parts have similar functions to those of the first embodiment in FIGS. 1 through 11, identical reference numerals will be used where appropriate with the prefix 200. It will be noted that in this embodiment the front pressed plate 10 of the first embodiment has been replaced with a front plate 210 of a cast skeleton design. The front plate 210 is of a substantially planar X -shape and includes means, in the form of screw holes 226, for securing a flat panel display to its front surface 210 a. The rear of the front plate 210 is configured for engagement with a rear component 211 of the adjustable mount. As can be seen from FIGS. 18 and 19, the rear of the front plate 210 includes an annular projecting element 240 disposed just above the center of the X. Within the diameter of the annular element 240 are provided upper and lower slots 241 a, 241 b, respectively, which are configured to receive complementary projections 242 a, 242 b of the rear component 211, described below. The slots 241 a and 241 b are configured such that a certain degree of relative rotation of the front plate 210 with respect to the rear component 211 is permitted. The degree of relative rotation being defined by the length of the slots 241 a, 241 b in which the projections 242 a, 242 b are free to travel. A hole 243 is provided in the front plate 210, centrally of the annular element 240. The hole 243 is configured to align with a complementary hole 244 on the rear component 211, as described below. A pivot shaft 245 is disposed through the respective holes 243 and 244 in order to provide an axis for rotation of the front plate 210 with respect to the rear component 211. At least one end of the pivot shaft 245 is threaded to allow attachment of a nut (not shown) to secure the front plate 210 and rear component 211 together. A spacer may be provided to ensure that the nut is not over tightened to thereby hinder the desired rotation. Also provided on the rear of the front plate 210, adjacent to an extreme end of a lower leg of the X, is a screw-threaded hole 247. The hole 247 allows for horizontal leveling of the front plate 210 as will be described below.
