This invention relates to a wall mounting system for bathroom or kitchen accessories.
Bathroom and kitchen accessories, for example towel rails, hooks, towel rings, soap dishes and the like, have to be attached to a wall surface with a mounting means. This means must be aesthetically pleasing and have the ability to attach the rail securely to the wall with a degree of permanence.
The problem with such means is that they are often visually expose part of the componentry used to attach the rail thus detracting from the aesthetics of the accessory.
Furthermore, an installer when installing the accessory, often does so incorrectly thus resulting in the rail loosening from the mounting means and, possibly, eventually detaching completely from the wall.
The invention aims to at least partially address the aforementioned problems.
The invention provides a mounting system for a wall mounted accessory which includes a first component, which is attachable to a wall, having a spigot, and a second component, to which the accessory is attached, which has a tubular element and a clamping means which projects into an interior of the tubular element, which has, at one end, a clamp head and which is actuatable, when the tubular element is passed over the spigot and the spigot is located between the clamp head of the clamping means and an inner wall of the tubular member, to draw the clamp head into abutment with the spigot to clamp the spigot between the clamp head and the inner wall.
The spigot may be a cleft spigot. To locate the spigot between the clamp head and the inner wall, the clamping means may pass into the cleft of the spigot.
The wall mounted accessory may be a towel rail, a towel ring, a soap dish or the like.
The first component may have a mounting plate from which the spigot projects. The base plate may be holed to allow a fastening means, for example screw or a nail, to pass to attach the first component to the wall.
The spigot may have an annular seat.
The accessory may include a holed cover plate that, in use, cover the mounting plate and which is holed to pass over the spigot to locate on the annular seat.
The clamping means may include a threaded elongate member, such as a screw, to which is engaged, at one end, the clamp head. When the threaded member is actuated, by rotation, the clamp head is drawn, along the threads of the member, towards the spigot.
The spigot may include a recessed formation within which the clamp head locates.
The recessed formation may have a base and sloping surface which, in use, faces the wall and which leads to the base. The sloping surface may direct the clamp head axially inwardly, towards the wall, and downwardly towards the base.
The recessed formation may be adapted such that, when the clamp head is drawn therein, an axial force is imposed that draws the second component axially towards the first component.
Preferably, the clamp head is barrel shaped.
Another aspect of the invention provides a mounting system for a wall mounted accessory which includes a first component, which is attachable to a wall, having a cleft spigot, and a second component, attached to the accessory, which has a tubular element and a clamping means, which is located in the tubular element, having at one end a clamp head, wherein, when the tubular element engages with the spigot in attachment of the accessory to the wall, the clamping means at least partially locates within a cleft of the spigot to position the clamp head adjacent an inner-facing side of the spigot, and wherein the means is actuable to draw the clamp head into abutment with the spigot to clamp the spigot between the clamp head and an inner wall of the tubular element.
The invention is further described by way of examples with reference to the accompanying drawings in which:
The first component 12 includes a circular wall mount plate 24, through which is formed a pair of arc shaped slots 20 (see
From the plate 24 projects a cleft spigot 30 mounted atop a cylindrical base 32. An annular seat 34 is defined between the base and the spigot (see
The clamping means 22 includes, in this particular embodiment, a blunt-end screw 42 which is passes through a hole 44 formed in a wall of the tubular element 20 to project into an interior of the element, with a head end 46 abutting up against the hole perimeter. A clamp head 46 is threadedly engaged with a threaded end 48 of the screw. The clamp head is barrel shaped and has a pair of locating formations 50 which, when the clamp head is engaged with the screw, project towards the hole. The clamp head is complementarily shaped to the base 43 of the recessed formation 40 as illustrated in
To mount the accessory 16 to the wall, firstly, a vinyl circular sticker 52, which is of complementary dimension to the plate 24, is applied to the wall, in a position which, ultimately, is desired for the mounting system 10 and wall mounted accessory 16. Each side of the sticker has an adhesive substance to aid in adherence of the sticker to the wall and the plate to the sticker. The sticker can have circular marks 54 pre-marked thereon to indicate, to an installer, where to make the plugged drill holes 28.
After making the drill holes 28, the plate 18 of the first component is then placed over the sticker and appropriately positioned so that each slot 20 is partially in register with a respective drill hole. A screw 26 is then passed through each slot, into each plugged drill hole, and then after an opportunity to manipulate the position of the plate as described above, the screws are screwed into their respective holes to fasten the plate, and the first component 12, firmly in place on the wall 13. A wall facing surface 56 of the plate can include a plurality of ridged formations (not shown) to improve the adherence of the plate to the sticker.
Thereafter, a holed cover plate 58 is passed over the first component 12 until a perimeter edge 60 of a cover plate hole 62 abuts the seat 34. In this position, a leading annular rim 64 of the cover plate does not touch the wall 13 to ensure that when the second component 14 is attached with the first component 12, the forces imposed by the attachment are transmitted through the first component and not through the cover plate, which will potentially buckle the plate. However, to maintain aesthetics, the gap between the wall and the rim 64 is very small.
An open end 66 of the tubular element 20 is then passed over the spigot 30, as a shaft 68 of the screw 42 slots into the cleft 38, aided by the guiding formations 50 of the clamp head 46 which ensure that the clamp head is appropriately positioned to lie transverse to the direction of passage (see
To secure the second component 14 to the first component 12, an alien key, for example, is engaged with a complementary recess which is externally presented in the head 46 of the screw 42 to axially rotate the screw thereby driving the threaded end 48 of the screw into and through the clamp head 46. The clamp head is prevented from rotating, as the screw 42 is rotated, by the locating formations 50 and the clamp head itself abutting the walls of the cleft 38 and a pair of clawed projections 70, one each at the end of each finger 36. Thus, the turning of the screw 42 in the clamp head has the effect of drawing the clamp head towards the recessed formation until the clamp head comes into contact with the formation 40 as illustrated in
With further rotation of the screw, the clamp head 46 comes into contact, and is drawn along, the sloping surface 41 of the recessed formation 40. The slope of the surface 41 forces the clamp head downwardly, towards the base 43, and inwardly, towards the wall 13. An axially directed force is thereby imparted on the clamp head, and the tubular member element 20, to draws the open end 66 tightly against the cover plate 58, as illustrated in
The transverse “clamping” force imposed by the downward movement of the clamp head on the recessed formation 40, as it continues its advance down the threads of the screw 42, draws the spigot 30 tightly against an inner wall 72 of the tubular element 20. The spigot is, essentially, clamped between the clamp head and the tubular element's inner wall, thereby fixing the second component 14, and the accessory 16, which in this case is a hook 18, to the mounting component 12.
By employing the mounting system 10, in accordance with the invention, the accessory 16 is securely attached to the wall 13 without loosening over time, at the point of attachment, to the same extent and rate as is the case with prior art systems.
Prior art systems typically employ grub screws to attach the counterparts of the first or the second component (12, 14) together. A grub screw will pass through a threaded aperture in one of the components to engage the other inner component fitted therein. The point of the grub screw contacts the surface of this inner component and pushes the component, in an expansive manner, against the outer component.
The disadvantage of such as system is inherent in the grub screws, which are relatively delicate with thin walls that are easily deformed when there are repeated attempts at tightening them with an alien key, and the threads of the aperture and the grub screw, which are prone to deformation due to the forces imposed through the grub screw by movement of the components. The degradation of the grub screws and the threads cause such mounting systems to loosen.
