Description

Field of Invention The present invention relates to safety mountings and in particular a safety mounting providing a re-useable breakaway joint for use in suspending an article, e.g. a PPE dispenser, toilet roll holder, window curtain rail. Background of the Invention An issue in certain institutions (e.g. Psychiatric wards, Prisons, Hospitals) is the increasing number of persons attempting suicide by ligature from a fixed point, by suspended articles, e.g. a curtain bracket or other mounted holder. Whilst various attempts have been made to mitigate this risk, broadly all solutions provide a breakaway portion that detaches the item from the mount to prevent use of the mounted item as a ligature point. However a consequential issue of various inventions is that the breakaway portion becomes a weapons risk A Known safety joint addressing this problem is disclosed in GB2308406 where a plug and socket joint is provided with a load responsive retaining means that the plug releases at a predetermined load. A disadvantage of this solution is that the load not only diminishes over time, but also that a readily available foreign object (e.g. blue tack or chewing gum) can be used to compromise the load release. A further known safety mount is disclosed in GB2351758, with similar magnetic properties, providing ‘fail-safe’ detachment at a predetermined load. A disadvantage of this known safety mount is that the magnet is exposed, leaving a joint around the magnet which is prone to tampering and gaining a horizontal lip with which to attempt a ligature. Another known safety mount is available which provides a planar surface with which to attach an object (e.g. a towel dispenser). This is attached using magnets from the said system disclosed on GB2351758. A disadvantage of this existing invention is that the said planar surface - typically made of polycarbonate, with a tapered edge on all sides - becomes a heavy weapon with axe-like properties when detached . The present invention aims to at least ameliorate the above mentioned issues. Summary of the Invention According to a first aspect of the present invention there is provided a mounting system for releasably securing an object to a walled surface, said system comprising: at least one magnetic element with corresponding counterpart; a mounting plate having attachment means for securing the plate to the walled surface, said mounting plate comprising: an exterior surface for releasably securing the object thereto; an interior surface for securing to the walled surface; one or more indentations in the exterior surface for receiving the counterpart; and one or more recesses in the interior surface, said recesses substantially aligned with the one or more indentations; and wherein the at least one magnetic elements are located within the recesses and the counterparts are coupled to the object to magnetically attach the object to the walled surface when the counterparts are received in the indentations. The present system provides a mounting system for attaching one or more objects, such as PPE dispensers, curtain rails, toilet roll holders and the like. If force is applied to the object that is higher than the magnetic attraction holding the object to the exterior surface, the object is released from the mounting plate due to the counterpart disengaging with the magnetic element as it disengages the indentation. This ensures that the mounted object does not pose a ligature risk when used within secure facilities having patients and / or inmates having a ligature risk. In an embodiment the indentations may be unitary with the exterior surface to form an unbroken exterior surface. This allows for a smooth surface for the mounting plate, which reduces infection risk due to ease of cleaning. Preferably the recesses may be shallower than the thickness of the mounting plate to encapsulate the magnetic elements within the mounting plate. Additionally, by 2 housing magnetic elements behind the exterior surface it is more difficult for these to be extracted from the system for malicious use by an inmate, patient, or prisoner. In one embodiment the recesses may not be visible from the exterior surface. Similarly, the at least one magnetic element may be embedded within the mounting plate. Typically, the mounting plate is a plastics material. This allows for ease of cleaning and is magnetically permeable for the at least one magnetic element to allow objects to be magnetically affixed through the mounting plate. In some embodiments the mounting plate may comprise a smooth front face profile, and wherein edges of the front face profile may be angled to avoid ligature points. By angled it is intended to include chamfered surfaces angling the exterior surface towards any exterior surface to aid having a flush surface when the mounting plate is attached to a walled surface. Typically the counterpart may comprise a ferromagnetic material for magnetic coupling to the magnetic elements, and the counterpart may further comprise a contoured lower surface shaped to juxtapose with the indentations and a flat top surface to form a co-planar surface with the exterior surface. Typically the flat top surface comprises attachment means for coupling the counterpart to the object, and said attachment means may comprise a countersink for coupling the counterpart flush against the object. The flat top surface may also comprise a lug covering capping the ferromagnetic material to protect the material and prevent tampering. Typically the magnetic elements are permanent magnets. These provide a tailorable magnetic attachment strength and a more secure and cheaper attachment. In embodiments a plurality of magnetic elements may be provided, said elements being spaced to allow mounting of the object in one orientation only. In an example, a plurality of magnetic elements may be provided, said elements being spaced to allow mounting of the object via correspondingly spaced magnetic counterpart elements of the object in one orientation only. The spacing may be irregular or may be arranged in a pattern such that only objects having counterparts arranged in the same manner can be affixed to the exterior surface. The spacing may be selected to provide for horizontal or vertical mounting. It may also be appreciated that multiple arrangements may be provided in a single mounting plate, with each arrangement configured to match with a specific object. This can allow different shaped objects to be secured to a single mounting system without providing too high a magnetic force. As an example, an attachment force of the magnetic mounting may be configured to be weaker than 250 Newtons to allow the object to be easily released from the exterior surface. Typically the counterpart comprises magnetic material, for magnetic securing to the magnetic element - such magnetic material may include ferromagnetic materials, such as magnetic stainless steel. The counterpart may be countersunk within countersink indentations in the object. The countersink indentations may provide a continuous surface, such as with curved surface on outer edges, that aids cleaning when compared to holes or the like. The counterpart may secured within the countersink indentations by a rivet. A lug covering may be used with said attachment means to provide a flat surface for mounting the object flush to the exterior surface of the mounting plate. These also ensure that the attachment means are never exposed for infection control purposes. Indentations may be provided at spacings applicable to the counterpart (e.g. different for different objects such as a toilet roll holder, PPE dispenser etc). The mounting plate may be made of either moulded or machined plastics material. According to second aspect of the present invention there is provided a mounted object for releasable attachment to a walled surface, said walled surface comprising a mounting system according to any embodiment of the first aspect, and further comprising at least object secured to the at least one counterparts for magnetically securing the object to the mounting plate via the at least one magnetic elements.. These and other aspects of the invention will be apparent from, and elucidated with reference to, the embodiments described hereinafter. Brief description of Drawings Embodiments will be described, by way of example only, with reference to the drawing, in which: Figure 1 illustrates a front side of the mounting system having magnetic elements according to an embodiment of the present invention; Figure 2 is a rear view of the mounting system of figure 1; Figure 3 is a view of a magnetic counterpart for magnetic attachment to the magnetic elements of Figure 1; and Figure 4 is a schematic of a mounted object magnetically secured to a walled surface using the mounting surface of Figure 1. It should be noted that the Figure is diagrammatic and not drawn to scale. Relative dimensions and proportions of parts of the Figure have been shown exaggerated or reduced in size, for the sake of clarity and convenience in the drawings. The same reference signs are generally used to refer to corresponding or similar feature in modified and different embodiments. Detailed Description Figure 1 shows a schematic of a front side of a mounting system 10. The mounting system comprises a mounting plate having an exterior surface 11. Within then exterior surface 11 are one or more indentations 12 that form depressions on the exterior surface such that the exterior surface is continuous. This aids cleaning and reduces crevices in which bacteria can reside. The exterior surface forms a solid planar surface that can be tailored to be large enough to mount a desired object, such as a PPE dispenser, toilet roll dispenser, curtail rail or the like. The mounting plate comprises attachment means, in the present example holes, in which fasteners, such as screws or the like, can be used to secure the mounting plate to a walled surface. The holes are typically countersink holes in which a corresponding fastener can be countersunk. Caps 14, may be used to fill the hole after fixing, said caps or lugs 14 providing a flush surface with the exterior surface to again aid infection control. This also acts to provide an anti-tamper measure to help prevent access to the fastener within the holes, which may be used by inmates or prisoners when the present system is used in a secure facility. Finally, the mounting plate comprises an outer perimeter. The depth of the outer perimeter may be tailored to allow for the use of deeper indentations or deeper recesses (as will be described below). The outer perimeter is typically angled, in the present example at around 15 degrees, but it can be considered that a greater angle, up to around 45 degrees may be used. The use of such an angled surface is to reduce potential ligature points that could be used to attach a ligature. Figure 2 shows the rear of the mounting plate, with an interior surface 21 shown. The corresponding internal holes 21 of the fixing holes 14 are shown. Also shown are a plurality of recesses 22. The recesses are positioned substantially behind the indentations on the exterior surface and are configured with a depth to not permeate the depth of the mounting plate. Magnets 24, or other magnetic elements, can be placed and housed within the recesses 21. The magnets are typically configured to sit within the recesses and to lie flush or slightly recessed from the interior surface. Although shown as circular, the recesses 21 and the corresponding magnets 24 can be any shape that best suits the mounting plate. Additionally, although shown a single components, the mounting plate may comprise separate components that each provide one of the interior and exterior surfaces and are then interconnected through holes 14 and 23 when affixed to a wall or other surface. Figure 3 shows a counterpart piece 30 that is correspondingly shaped to lie in indentation 12 of the exterior surface. The counterpart is typically magnetic stainless steel for infection control purposes. The counterpart has a curved lower portion 31 configured to fit in a juxtaposed manner into the indentations 12. A flat top portion 32 is provided and allows the counterpart to have a flush fit with the mounting plate 10. The top portion comprises a pre-drilled countersink hole 33, to allow fixing of the counterpart by rivet or the like to an object. In use, one or more counterparts 30 are affixed to an object using the countersink holes 33. The counterparts are spaced according to the spacing of the indentations 12 of the mounting plate 11. It can be appreciated that there may be more indentations that are not used, with the counterparts spaced to best accommodate the object to be affixed. Prior to installation, magnets 24 are secured within the recesses 22 using friction, rivets, glue or other means such that the magnets are flush or recessed from the interior surface. It can be appreciated that not all the recesses may be provided with magnets, depending on the weight and size of the object intended to be affixed to the walled surface. The mounting plate is affixed to a walled surface using attachment means (such as antitamper countersunk screws or the like) through holes 12, 23. The mounting plate is fastened to lie flat against the walled surface to minimise ligature points (aided by the angled edge 15). The counterparts 30 (attached to the object) can then be brought into alignment with the indentations 12 on the exterior surface. The magnetic elements 24 then magnetically engage with the counterparts 30 to magnetically secure the object to the mounting plate 10 and accordingly to the walled surface. This is shown in Figure 4, where the mounting plate 41 receives an object 42 (in this case a PPE dispenser) to which counterparts have been secured. The present invention allows for objects to be safely secured to a walled surface such that force applied to the object causes the object to disengage with the walled surface to reduce ligature risk. From reading the present disclosure, other variations and modifications will be apparent to the skilled person. Such variations and modifications may involve equivalent and other features which are already known in the art of safety door systems, and which may be used instead of, or in addition to, features already described herein.
