Description
CONTROL DEVICE COMPRISING WALL-MOUNTABLE BASE MEMBER AND
CONTROL UNIT
The present disclosure relates to a control device mountable on or in a wall. Such a control device is used for controlling systems that condition or maintain an environment, including electrical, lighting and heating equipment, heating and ventilation control systems, heating systems and the like.
Control devices of the above type are typically connected to electrical wiring for carrying control signals to and from the system to which the control device is connected. Their basic construction is reminiscent to those of certain wall-mountable electrical sockets or switches in that they comprise a wall-mountable component connected to said electrical wiring and an additional component with input and/or output means (e.g. a switch) configured to be attached to the wall- mountable component.
It is conceivable that in constructions as described hereabove, the wall-mountable component and the additional component are securely connected to one another using a screw or bolt connection or the like, as is the case with certain electrical sockets. However, it is known in the art that the connection between the wall-mountable component and the additional component may be constituted by a snap on coupling. which can be installed without using tools. Snap on couplings have been found to be sufficient to ensure that the additional component remains firmly installed on the wall-mountable component, without being detached therefrom or shifting relative thereto in the axial or radial direction, which may otherwise occur the additional component is manipulated by a user during use.
Snap on couplings consist of mutually engaging or mechanically interlocking elements disposed on the wall-mountable component and the additional component. These mutually engaging or mechanically interlocking elements may include mutually engaging catches and latches, flanges, tabs, ribs, teeth, collars, braces, grooves, lugs and the like that retain the additional component relative to the wall-mountable component and can be installed without using tools.
Nevertheless, known snap on couplings for wall mounted control devices are associated with a number of disadvantages. Firstly, the mutually engaging or interlocking elements disposed on the first and second members are susceptible to damage. Protruding latches, ribs, tabs, teeth that form part of the snap on coupling may easily bent or snap during or before installation of the control device, resulting in either one or both of the wall-mountable component and the additional component needing to be replaced.
A further disadvantage of known snap on couplings for wall mounted control devices is that, while they are easily installed without requiring tools, their removal is more complicated.
Typically, some sort of prying tool such as a screwdriver is required to cancel the interlocking mechanical connection and thereby separate the wall-mountable component from the additional component. Although the necessity of using a prying tool is considered a disadvantage in itself, it may moreover result in damage to the wall-mountable component from or the additional component, or to the wall on which the control device is installed. This is considered particularly problematic when the control device is temporarily removed only to be reinstalled later.
A third disadvantage is that at present, the various snap on couplings for wall-mountable control devices available on the international market have diversified forms, no uniform style and size, and a single installation structure.
The objective of the present disclosure is to provide a control device of the hereabove described type with which one or more of the hereabove described disadvantages are obviated or abated.
This objective is achieved with a control device according to appended claim 1, comprising a wall-mountable base member, and a control unit comprising at least input means for obtaining user input and output means for outputting information to a user, wherein the control unit is connectable to the surface of the wall-mountable base member unit with an intermediate member interposed therebetween, wherein the control unit is mountable to the wall-mountable base by means of an axial coupling between the wall-mountable base member and the control unit constituted by a magnet pair with a first magnet comprised by the wall-mountable base member and a second magnet comprised by the control unit, the axial coupling preventing movement of the control unit relative to the wall-mountable base member in at least an axial direction, and a radial coupling between the wall-mountable base member and the control unit constituted by at least one additional magnet pair with a third magnet comprised by the wall-mountable base member and a fourth magnet comprised by the control unit. the radial coupling preventing movement of the control unit relative to the wall-mountable base member in a radial direction.
The above described control device according to the present disclosure advantageously does not comprise a snap on coupling with interlocking latches and latches, flanges, tabs, ribs and the like, while simultaneously providing adequate fixation in both the axial and radial directions.
Damage to any protruding components constituting a snap on coupling is therefore entirely prevented. The control device according to the present disclosure moreover does not require tools during installation or removal, which further diminishes the risk of damage to both the control device itself and the wall on which it is mountable.
The control device according to the present disclosure is moreover compatible with a variety of intermediate members of different styles and sizes on the market while being firmly installed on the room wall in both the radial and axial directions. A desired wall panel uniformity and aesthetic appearance may thus be achieved relatively easily.
In a preferred embodiment of the control device, at least one of the first magnet, the second magnet, the third magnet and the fourth magnet is movable in the axial direction relative to the wall-mountable base member or the control unit.
Said magnet being movable in the axial direction relative to the wall-mountable base member or the control unit ensures that the magnets constituting a magnetic pair physically contact one another when the control device is mounted on the wall, thereby ensuring that the magnetic connection between said magnets is at all times optimal. This embodiment of the control device is considered particularly advantageous for walls having a rough finishing or imperfections that would otherwise prevent said magnets from physically abutting one another. Moreover, decorative intermediate members with varying thicknesses may be interposed in between the wall-mountable base member and the control unit.
In a further preferred embodiment of the control device, the magnet being movable in the axial direction is arranged in an axial guide comprised by either the wall-mountable base member or the control unit, wherein the being movable in the axial direction is translatable in the axial direction within said axial guide.
In a further preferred embodiment of the control device, the magnet being movable in the axial direction is spring loaded.
In a further preferred embodiment of the control device, the input means of the control unit is a touch-based input means.
In a further preferred embodiment of the control device, the input means and the output means comprise a touch screen.
In a further preferred embodiment of the control device, the radial coupling further comprises a friction enhancing material interposed between the control unit and the intermediate member.
In a further preferred embodiment of the control device, the friction enhancing material comprises detachable compressible foam.
In a further preferred embodiment of the control device, the intermediate member comprises an opening and at least one of the wall-mountable base member and the control unit comprises a protrusion configured to be form-fittingly received by said opening of the intermediate member.
The control device according to the present disclosure is elucidated here below with reference to the appended drawing, in which:
Figure | shows an exploded view of various components comprised by an exemplary embodiment of a control device according to the present disclosure;
Figure 2 shows a perspective view of a control unit comprised by the control device of
Figure 1;
Figure 3 shows a first cross-sectional view of the control device of Figure 1 and Figure 2 in an installed state; and
Figure 4 shows a second cross-sectional view of the control device in the installed state.
A control device 1 according to the present disclosure is mounted on or in a wall 12 and used to control a system (not shown) for conditioning an interior space. Systems that may be controlled by the control device 1 include, for example, electrical, lighting and heating equipment, heating and ventilation control systems, heating systems and the like. The control device 1 may be used to input a desired system parameter (e.g. a desired temperature) and output one or more system parameters (e.g. a set or current temperature) to a user. The control device 1 is electrically connected to the system via wiring 13 that is preferably embedded into the wall 12, although it is conceivable that communication with the system is performed wirelessly using a wireless communication scheme known in the art. Electrical connectors, sensors, switches and the like may be provided for interfacing the control device 1 with the system.
The control device 1 comprises a wall-mountable base member 2 that is installable on or in the wall 12 having a frontal surface 2’ that remains exposed. One or more screw holes 7 may be provided to securely fixate the wall-mountable base member 2 to the wall 12.
The control device 1 moreover comprises a control unit 3 that is coupled to the wall- mountable base member 2. A user may set system parameters and obtain information about the system to which the control device 1 using the control unit 3. For example, a user may set a desired temperature, fan speed, etc. via the control unit 3. As such, the control unit 3 comprises input means such as an on/off switch 11, buttons and the like); and output means such as a screen or loudspeaker (not shown). In preferred embodiments, the control unit 3 comprises a touch screen 6, which can simultaneously obtain user input and output relevant information. In such embodiments, the dimensions of the touch screen 6 may substantially correspond to the dimensions of the control unit 3, such that the touch screen 6 covers substantially the entire frontal surface of the control unit 3 when viewed in the direction along the Z-axis in Figure 1.
The wall-mountable base member 2 and the control unit 3 may respectively comprise electrical connectors 9, 9’ to convey electrical signals representing the aforementioned inputs and outputs. Power may be supplied to the control unit 3, in particular to the touch screen 6, via the electrical connector 9 of the wall-mountable base member 2. Alternatively, wireless communication may be provided for conveying signals and supplying the touch screen 6 with power. An intermediate member 4 is interposed between the wall-mountable base member 2 and the control unit 3. The intermediate member 4 may enclose the edges of the mountable base member 2 to protect it from the external environment. The intermediate member 4 may moreover have a decorative function that gives the control device 1 a finished, esthetic appearance. In the depicted embodiment, the intermediate member 4 is a frame with an opening 4’. The control device 1 according to the present disclosure is compatible with intermediate members 4 having varying thicknesses.
In addition, a friction enhancing member 5 is likewise interposed between the wall- mountable base member 2 and the control unit 3. In the depicted exemplary embodiment, the 5 friction enhancing member 5 is interposed between the intermediate member 4 and the control unit 3. As will be elucidated here below, the friction enhancing member 10 may retain a position of the intermediate member 4 relative to the wall-mountable base member 2 and the control unit 3 in radial directions defined by the plane of the X and Y axes in Figure 1.
The friction enhancing member 5 may likewise have a frame-like shape with an opening 5 and may comprise a compressible material such rubber, compressible foam, or the like.
The control device 1 is installed by first mounting the wall-mountable base member 2 on/in the wall 12. followed by coupling the control unit 3 to the connecting surface 2° of the wall- mountable base member 2. The intermediate member 4 and the friction enhancing member 5 are interposed between the wall-mountable base member 2 and the control unit 3.
In order for the control device 1 to be adequately installed, the control unit 3 must be coupled to the wall-mountable base member 2 with respect to both the axial direction (in the direction of the Z axis in Figure 1) and the radial directions (in the plane of the X-axis and the Y- axis in Figure 1). This prevents the control unit 3 from being pulled off the wall 12 in the axial direction of the Z axis or rotate/shift relatively to the wall 12 in the radial direction, which is in the direction of the X- or Y-axis, when a user manipulates the input and output means of the (e.g. the touch screen 6) of the control unit 3. Consequently, the coupling between the wall-mountable base member 2 and the control unit 3 comprises at least one axial coupling and at least one radial coupling. In the control device according to the present disclosure, the axial and radial couplings are both constituted by magnet pairs (8a, 8a’; 8b, 8b’; 8c, 8¢’; Sd, 8d") of magnets comprised by the wall-mountable base member 2 and the control unit 3.
Figure | shows the wall-mountable base member 2 having disposed on its connecting surface 2° a plurality of magnets 8a, 8b, 8c, Sd. Each of these magnets is arranged to form a magnet pair with a respective one of a further plurality of magnets 84’, 8b’, 8e’, 8d’ comprised by the control unit 3 as depicted in Figure 3. While the depicted embodiment shows the wall- mountable base member 2 and the control unit 3 each comprising four magnets 8a, 8a’; 8b, 8b’; 8c,
Sc’; 8d, 8d’, the number of magnets can be arbitrarily selected and is generally at least two.
Referring now to Figures 3 and 4, the axial coupling between the wall-mountable base member 2 and the control unit 3 is constituted by at least one first magnet pair comprising a first magnet (e.g. magnet 8b) comprised the wall-mountable base member 2 and a correspondingly arranged second magnet (e.g. magnet 8b’) comprised by the control unit 3. These magnets 8b, 8b’ are arranged to have opposite polarities relative to one another.
The axial coupling constituted by the first and second magnets 8b, 8b’ has been found to be sufficient to ensure that that the control unit 3 cannot move relative to the wall-mountable base member 2 in the axial direction (i.e. the direction of the Z axis in Figure) at least during normal usage of the control device 1. The control unit 3 therefore remains attached to the connecting surface 2" of the base member 2 and is not decoupled therefrom as a result of gravity, a user manipulating the manipulating the input means, or a user accidentally nudging the control device 1.
The first and second magnets 8b, 8b’ are preferably neodymium magnets and are arranged to abut one another in the assembled state of the control device 1 depicted in Figure 3 and Figure 4, such that the generated magnetic force is optimal.
Notwithstanding the above, the axial coupling by itself may not fixate the control unit 3 relative to the base member 2 in the radial directions (i.e. in the plane by the X- and Y- axes in
Figure 1). Assuming that only this axial coupling constituted by the magnets first and second magnets 8b, 8b’ is present, the control unit 3 may still shift or rotate relative to the base member 2, which is unwanted for aesthetic reasons and may result in the control unit 3 being electrically disconnected from the base member 2.
In order to prevent the above from occurring, the control device 1 comprises a radial coupling between the wall-mountable base member 2 and the control unit 3 in addition to the hereabove described axial coupling. The radial coupling is constituted by at least one additional magnet pair comprising a third magnet 8c disposed on the connecting surface 2° of the wall- mountable base member 2 and a fourth magnet 8c’ comprised by the control unit 3. The third magnet 8c and the fourth magnet 8c’ are disposed such that they align with one another when the control unit 3 is arranged on the connecting surface 2° of the base member 2 as depicted in Figure 4.
The at least one additional magnet pair 8c, 8c’ forms a second coupling point that — in conjunction with the above described radial coupling formed by the first magnet 8b and the second magnet 8b” — prevents the control unit 3 from shifting or tilting relative to the wall 12 and the mountable base member 2. As such, the control unit 3 is securely coupled wall-mountable base member 2 in both the axial direction and the radial direction.
On account of the axial and radial couplings constituted by the first and second magnets pairs 8b, 8b’; 8c. 8c’, the control device 1 according advantageously does not comprise any interlocking latches and latches, flanges, tabs, ribs or the like which otherwise might easily become damaged during installation or removal of the control device 1. Moreover, the control device 1 advantageously does not require tools for installation or removal.
The intermediate member 4 is interposed in between the wall-mountable base member 2 and the control unit 3. The magnetic force in the axial direction generated by the magnet pair(s) as described hereabove is transferred to the wall-mountable base member 2 and the control unit 3 and is sufficient to clamp the intermediate member 4 in place. The friction enhancing member 5 arranged between the control unit 3 and the intermediate member 4 generates a friction force that prevents the intermediate member 4 from radially shifting/tilting relative to the control unit. As such, the friction enhancing member 5 is considered to be part of the radial coupling according to preferred embodiments of the control device 1. The friction enhancing member 5 may comprise compressible foam, rubber, and the like.
The control unit 3 preferably moreover comprises a protrusion 1Ô extending in the axial direction and dimensioned to be form fittingly received by the opening 4’ of the intermediate member 4. The form fit between the protrusion 10 the opening 4’ prevents rotation of the intermediate member 4 relative to the control unit 3 and thus is considered to form part of the radial coupling according to the present disclosure. It is noted that the protrusion 10 may alternatively be comprised by the wall-mountable base member 2.
The magnetic force generated by the magnets 8a-8d’ constituting a given magnet pair is dependent on the distance between said magnets 8a-8d’. The magnetic force is optimal when said magnets abut one another, as is the case in Figure 3 and Figure 4. Misalignments between two magnets 8a-8d” constituting a given magnet pair may result from e.g. an intermediate member 4 with a relatively large thickness having been selected, the wall-mountable base member 2 being embedded too deeply in the wall 12, or the wall 12 having a rough surface resulting from damage or the wall 12 having a rough finishing. While relatively small misalignments between magnets constituting a given magnet pair generally do not result in a decoupling of the control unit 3 from the wall-mountable base member 2, it is nevertheless preferable to at least minimize this intermediate distance and even more for said magnets 8a-8d’ to abut one another.
In order to facilitate this, at least one of the magnets 8a-8d’ comprised by either one of the wall-mountable base member 2 and the control unit 3 is preferably movable in the axial direction.
In other words, said at least one magnet 8a-8d’ has a variable pitch. In the exemplary embodiment of the control device 1 depicted in the appended drawing, magnet 8a’ and magnet 8c’ of the control unit 3 are each arranged in a respective axial guide 16, 17 or slot comprised by the control unit 3.
Magnet 8a" and magnet Sc’ may thus easily bridge the intermediate distance to their respective counterpart magnets 8a, 8c, such that these magnets abut one another or at least such that said intermediate distance is minimised.
The at least one magnet 8a’, 8c’ having the variable pitch is preferably spring loaded. From
Figure 4 it can be discerned that springs 14, 15 are in each respective slot 16, 17 of the variable pitch magnets 8a, 8c. The springs 14, 15 maintain their respective magnets 8a, 8c in an outwardly oriented location relative to the control unit 3, which further facilitates easy installation of the control unit 3 on the wall-mountable base member 2.
Preferably at least one but not all of the magnets 8a-8d’ may comprise a variable pitch and is more preferably spring loaded with a spring 14, 15. While appended Figure 4 shows the control unit 3 comprising the at least one variable pitch magnet 8a, 8c, it may alternatively be comprised by the wall-mountable base member 2.
The input means 5 of the control unit 3 is preferably a touch-based input means 5 and may comprise one or more buttons, switches, dials and the like. In even more preferred embodiments, the input means 5 is constituted by a touch screen.
The present disclosure proposes a control device 1 mountable in or on a wall 12 for controlling a system and comprising a wall-mountable base member 2 and a control unit 3, which are coupled to one another an axial coupling and a radial coupling, the axial and radial couplings each being constituted by two respective magnet pairs 8a, 8a’; 8b, Sb’: 8c. 8¢’; 8d, 8d’ of magnets arranged on the wall-mountable base member 2 and a control unit 3, whereby the control device does not require the interlocking mechanical members of comparable control devices known in the art. The present disclosure moreover relates to a wall-mountable base member 2 and to a control anit 3 comprised by such a control device 1.
It is emphasised here that the present disclosure is not limited to any one of the exemplary embodiments described hereabove and depicted in the appended figures. The skilled person will acknowledged that certain modifications can be made to these embodiments without departing from the basic technical principles of the present disclosure. The scope for which protection is sought should therefore not be interpreted as being limited to one or more of these embodiments, but is instead defined solely by the claims and, at least in certain jurisdictions, their equivalents.
