This is located on the opposite major side to the spacer and has at least one mounting pin 142 which extends through the second hinge leaf and the spacer to secure both to the sash. The attachment member may also have an adjustment aperture 146 which receives an adjustment threaded fastener 147. This allows lateral movement of the second hinge leaf relative to the sash. A cover 150 may be secured to the opposite major side to the spacer.

Description

TECHNOLOGICAL FIELD Examples of the disclosure relate to a reversable hinge. In particular, they relate to a reversable hinge for a door or window which can be reversed for left or right mounting. BACKGROUND A hinge is a mechanical bearing that connects two solid objects. Hinges are used for doors and windows to connect the sash to the frame, where the sash is the movable part of a door or window. A hinge comprises two hinge leaves hingedly / pivotally connected by a hinge pin. It is useful for a single hinge to able to be used for both left and right configurations; where the hinge is positioned on the left or right side of the door or window. Some hinges have mechanisms to allow for vertical and lateral adjustment of the position of the sash relative to the frame. However such mechanisms require a certain vertical arrangement and so the hinge cannot be simply rotated to switch between left and right orientation. As such switching of orientation requires disassembling the hinge, flipping the orientation of one of the hinge leaves and then reassembling. This can be very time consuming and can lead to components of the hinge being lost. BRIEF SUMMARY According to various, but not necessarily all, examples there is provided a reversable hinge comprising, a first hinge leaf, a second hinge leaf and a spacer. The first hinge leaf is for connecting to a sash frame. The second hinge leaf is for connecting to a sash. The second hinge leaf is hingedly connected to the first hinge leaf and comprises first and second major sides that are substantially opposite to each other. The spacer is configured to be detachably connected to the first major side and is configured to be detachably connected to the second major side. The spacer may be configured to transition between being connected to the first major side and being connected to the second major side. The spacer may be configured to be positioned between the second hinge leaf and the sash when the reversable hinge and sash are attached. The spacer may be configured to maintain a clearance between second hinge leaf and the sash. The spacer may be configured to maintain a clearance of at least 2 mm between the second hinge leaf and the sash. The spacer may be configured to maintain the second hinge leaf and the sash substantially parallel to each other.

DETAILED DESCRIPTION The figures illustrate examples of a reversable hinge 100. The reversable hinge 100 comprises a first hinge leaf 110, a second hinge leaf 120, and a spacer 130. The first hinge leaf 110 is for connecting to a sash frame. The second hinge leaf 120 is hingedly connected to the first hinge leaf 110 and is for connecting to a sash. The sash may be a door or window sash. The second hinge leaf 120 comprises first and second major sides 121, 122 that are substantially opposite to each other. The spacer 130 is configured to be detachably connected to the first major side 121 and is configured to be detachably connected to the second major side 122. The reversable hinge 100 is able to switch between left and right orientations without disassembly of the hinge 100. This provides the advantage that installation of the hinge 100 can be significantly quicker and easier. Fig. 1 shows an exploded view of an example of a hinge 100 according to examples of the disclosure. The hinge 100 has a height, length, and depth. For the illustrated hinge 100, the length is larger than the height and the height is larger than the depth. Coordinate axes 50 are illustrated in Figs 1 to 4 that include an x axis, a y axis and a z axis. The x dimension is aligned with the height of the hinge 100, the y dimension is aligned with the length of the hinge 100, and the z dimension is aligned with the depth of the hinge 100. The x, y, and z dimensions are orthogonal to each other. When the hinge 100 is attached to a sash and a sash frame, the height is parallel to the vertical extent of the sash and frame, the length is parallel to the lateral I horizontal extent of the sash and frame, and the depth is perpendicular to the surface of the sash and frame. Fig. 2 shows an example of a first hinge leaf 110 connected to a second hinge leaf 120 according to examples of the disclosure. The first hinge leaf 110 is best seen in Fig. 1, where it is shown in an exploded view. The first hinge leaf 110 includes a main body 111, a mount 170 and a mounting plate 174. The first hinge leaf 110 is configured to attach to a sash frame and may be considered to be the frame portion 110 of the hinge 100. The main body 111 comprises a base 112 and one or more knuckles 113. The illustrated main body 111 comprises a pair of outwardly projecting knuckles 113 at either end of the base 112. The illustrated main body 111 is slidably mountable to the mount 170. The base 112 comprises a channel (not visible) for receiving the mount 170, and the mount 170 comprises at least one groove 173 for engaging with the channel. A rib may be provided on an inner surface of the channel to engage with the groove 173 of the mount 170. The illustrated mount 170 comprises mounting pins 171 and apertures 172 for mounting screws. The mounting plate 174 comprises corresponding apertures 175 and acts to distribute the load. The mounting plate 174 may be different thicknesses to 7 accommodate different thickness doors. For example the thickness of the mounting plate 174 may be substantially 1 mm or 2 mm. The mount 170 and mounting plate 175 are attached to the sash frame using the mounting pins 171 and mounting screws, with the mounting plate 175 positioned between the mount 170 and the frame. Subsequently, the main body 111 is slid onto the mount 175. The first hinge leaf 110 is attached to the frame in a vertical orientation. A vertical adjustment screw 116 is mounted in a threaded aperture 114 of the base 112. This adjusts the vertical position of the main body 111 relative to the mount 170 and so adjusts the position of the first hinge leaf 110 relative to the sash frame. The illustrated first hinge leaf 110 also comprises end covers 115 which cover the channel and the knuckles 113. The hinge 100 also comprises a hinge pin 160 which is visible in Fig. 1. The second hinge leaf 120 is hingedly connected to the first hinge leaf 110 by the hinge pin 160. The hinge pin 160 defines a hinge axis which is parallel to the x axis. The first and second hinge leaves 110, 120 are configured to rotate about the hinge axis. The second hinge leaf 120 is pivotable through at least 175 degrees relative to the first hinge leaf 110. For example, through at least 180 degrees. As such, the hinge 100 can have both left hand and right hand configurations. In the illustrated example, the first hinge leaf 110 comprises two knuckles 113 and the second hinge leaf 120 comprises one knuckle 123. In other examples the hinge leaves 110, 120 may comprise different numbers of knuckles 113, 123. For example each hinge leaf 110, 120 may comprise one knuckle 113, 123. The hinge pin 160 is located between knuckles 113, 123 of the first hinge leaf 110, and the second hinge leaf 120. The illustrated hinge pin 160 comprises a recess 161 for engaging with a grub screw 117 to lock the hinge pin 160 in place. Bushing 162, 163, 164 is located around the hinge pin 160 and provides bearing surfaces for the knuckles 113, 123. The second hinge leaf 120 is best seen in Fig. 2. The second hinge leaf 120 may be considered to be a hinge flag 120 or plate 120. The second hinge leaf 120 is configured to attach to a sash and so may be considered to be the sash portion 120 of the hinge 100. The illustrated second hinge leaf 120 is longer than the first hinge leaf 110 and as such the hinge 100 may be considered to be a T hinge 100. The second hinge leaf 120 comprises a main body 124 and at least one knuckle 123. The illustrated main body 124 is substantially planar and substantially cuboid. In other examples the main body 124 may be a different shape, such as substantially cylindrical. In the illustrated example, the second hinge leaf 120 is substantially symmetrical about a plane defined by the x and y dimensions, and is substantially symmetrical about a plane defined by the z and y dimensions. The main body 124 comprises first and second major sides 121, 122, which form first and second major sides 121, 122 of the second hinge leaf 120. In Figs 1 and 2 only the first major side 121 is visible. The pair of major sides 121, 122 are opposite sides of the main body 124 and are configured to be substantially parallel to a sash when the hinge 100 is connected to the sash. In use, either side 121, 122 may be proximal to the sash. The major sides 121,122 are each substantially larger than the other sides of the main body 124. In some examples the first and second major sides 121, 122 are substantially identical. In particular, the first and second major sides 121, 122 are substantially identical in size and shape. The second hinge leaf 120 comprises at least one aperture 125. In the illustrated example the second hinge leaf 120 comprises a first aperture 125 and a second aperture 125. The first and second apertures 125 are elongate in the y dimension and are slots. The first and second apertures 125 are through holes extending from the first major side 121 to the second major side 122. The illustrated second hinge leaf 120 also comprises a locking bore 181 for receiving a locking threaded fastener 185. The locking bore 181 is a through hole and is threaded. When the locking threaded fastener 185 is fully received in the locking bore 181 rotation of the second hinge leaf 120 is prevented. A threaded fastener may be a screw or bolt. Fig. 3 shows an example of spacer 130 according to examples of the disclosure. The spacer 130 is best shown in Figs 1 and 3. The spacer 130 is configured to be connected to the second hinge leaf 120. The spacer 130 may be considered to be a packer 130 or a support 130. In some examples, the spacer 130 comprises a main body 131 and one or more walls 132. In some examples, the walls 132 are located at or proximal to the edge of main body 131 and extend in the z dimension. The illustrated spacer 130 comprises a pair of walls 132. The illustrated spacer 130 is substantially planer, is substantially cuboid, and is a similar size and shape to the second hinge leaf 120. In other examples the spacer 130 is a different shape and / or size and might not be similar to the second hinge leaf 120. In the illustrated example, the spacer 130 is substantially symmetrical about a plane defined by the z and y dimensions. The spacer 130 may comprise at least one aperture 135. In the illustrated example the spacer 130 comprises a first aperture 135 and a second aperture 135. In some examples, the first and second apertures 135 of the spacer 130 are configured to substantially align with the firstand second apertures 125 of the second hinge leaf 120 when the spacer 130 and second hinge leaf 120 are connected. In some examples, the first and second apertures 135 of the spacer 130 are configured to be substantially the same size and shape as the first and second apertures 125 of the second hinge leaf 120. As such, in some examples the first and second apertures 135 of the spacer 130 are elongate in the y dimension, are slots and are through holes. The spacer 130 is configured to detachably connect to either major side 121, 122 of the second hinge leaf 120 individually. The spacer 130 is configured to transition between being connected to the first major side 121 and being connected to the second major side 122. The reversable hinge 100 is configured such that: when the hinge 100 is in a left hand configuration, the spacer 130 is coupled to the first major side 121 and is positioned 10 between the second hinge leaf 120 and the sash, and when the hinge 100 is in a right hand configuration the spacer 130 is coupled to the second major side 122 and is positioned between the second hinge leaf 120 and the sash. To switch between the hinge 100 between the left hand and right hand configurations, the spacer 130 and second hinge leaf 120 are disconnected, the spacer 130 is moved to the other side of the second hinge leaf 120, and then the spacer 130 and second hinge leaf 120 are connected. In some examples, the same side of the spacer 130 connects to the second hinge leaf 120 in the two different configurations. In such examples the spacer 130 is flipped prior to reconnecting with the second hinge leaf 120. In some examples the spacer 130 is configured to be connected to and detached from the first major side 121 and / or the second major side 122 without the use of a tool. The spacer 130 may be configured to clip onto the second hinge leaf 120. The spacer 130 may be configured to connect to the edges 185 of the second hinge leaf 120. In some examples the spacer 130 and second hinge leaf 120 are configured to connect together with an interference fit. In the example of Fig. 1 it can be seen that the second hinge leaf 120 comprises one or more ledges 183 and the spacer 130 comprises one more corresponding recesses 184 for receiving the one or more ledges 183. The illustrated recesses are recesses in the walls 132 of the spacer 130. When the reversable hinge 100 and sash are attached, the spacer 130 is configured to maintain a clearance between the second hinge leaf 120 and the sash. In some examples the spacer 130 is configured to maintain a clearance of at least 1 mm between the second hinge leaf 120 and the sash, such as at least 2 mm, at least 5 mm, or 1 to 20 mm. The spacer 130 may have a thickness of at least 1 mm, such as at least 2mm, at least 5 mm or 1 to 20 mm. In use, the spacer 130 abuts, or is at least proximal to, the sash. In some examples, the spacer 130 is configured to maintain the second hinge leaf 120 and the sash substantially parallel to each other. This helps to ensure proper operation of the hinge 100. In some examples the spacer 130 is attached to the sash. The spacer 130 supports the second hinge leaf 120 and maintains the second hinge leaf’s 120 position relative to the sash. As such the spacer 130 improves the strength and stability of the hinge 100. The illustrated spacer 130 comprises a cavity 133 at its proximal end, the end closest to the hinge pin 160. The cavity 133 aligns with the locking bore 181 to accommodate the locking threaded fastener 185. In some examples, the reversable hinge 100 further comprises an attachment member 140 for attaching the second hinge leaf 120 to the sash. The attachment member 140 is configured to be detachably connected to the first major side 121 of the second hinge leaf 120 and is configured to be detachably connected to the second major side 122 of the second hinge leaf 120. The attachment member 140 is configured to transition between being connected to the first major side 121 and being connected to the second major side 122. Fig. 4 shows an example of an attachment member 140 according to examples of the disclosure. The attachment member 140 is best shown in Figs 1 and 4. The attachment member 140 may be considered to be a carriage plate 140 and / or an adjustment carriage member 140. In some examples, the attachment member 140 comprises at least one mounting pin 142 configured to mount the second hinge leaf 120 to the sash. The at least one mounting pin 142 may be considered to be an alignment pin 142. The illustrated attachment member 140 comprises a first mounting pin 142, a second mounting pin 143 (visible in Fig. 1) and a main body 141 connecting the first and second mounting pins 142, 143. The illustrated first and second mounting pins 142, 143 are located on the same side of the attachment member 140 and extend in substantially the same direction, which is parallel to the z dimension. In some examples, the main body 141 fixedly connects the first and second mounting pins 142, 143. In some examples the main body 141 is rigid. Compared to individual mounting pins, a main body 141 connecting first and second mounting pins 142, 143 is easier to handle and more difficult to drop or lose. This leads to faster installation times. In some examples the attachment member 140 comprises at least one aperture 145 for fixing the second hinge leaf 120 in place using at least one threaded fastener. In the illustrated example, the at least one aperture 145 comprises a plurality of apertures 145 for fixing the second hinge leaf 120 in place using a plurality of threaded fasteners. Each aperture 145 is spaced from another. In some examples the attachment member 140 comprises at least one mounting pin 142 but not at least one aperture 145, or the attachment member 140 comprises at least one aperture 145 but not at least one mounting pin 142. The illustrated attachment member 140 further comprises an adjustment aperture 146, for receiving an adjustment threaded fastener 147. The adjustment aperture 146 is a threaded aperture. The adjustment aperture 146 is a through hole substantially parallel to the y dimension. The adjustment aperture 146 is configured such that when the adjustment threaded fastener 147 is retained and the attachment member 140 and the second hinge leaf 120 are connected, the adjustment threaded fastener 147 abuts a portion of the second hinge leaf 120 and movement of the adjustment threaded fastener 147 causes relative movement of the attachment member 140 and the second hinge leaf 120. This allows for lateral movement of the second hinge leaf 120 relative to the sash. The second hinge leaf 120 and the spacer 130 each comprise a recess 128, 138 to accommodate the adjustment aperture 146 and the adjustment threaded fastener 147. In the illustrated examples the recess 128, 138 are though holes. The illustrated spacer 130 also comprises an opening 134 in the walls 132 to allow the adjustment threaded fastener 147 to be inserted into, and removed from, the adjustment aperture 146. The illustrated opening 134 is at the distal end of the spacer 130, the end furthest from the hinge pin 160 in use. The second hinge leaf 120 also comprises a receiver 129 for receiving the adjustment aperture 146 and / or the adjustment threaded fastener 147. The illustrated receiver 129 comprises at least one cylindrical recess. In the illustrated receiver 129 a gap is present between two parts of the cylindrical recess. In some examples a receiver 129 is present on each of the major sides 121, 122 of the second hinge leaf 120. The receivers 129 on each side 121, 122 are substantially identical. Fig. 5 shows an example of a hinge 100 in a left hand configuration according to examples of the disclosure. Fig. 6 shows an example of the hinge 100 in a right hand configuration according to examples of the disclosure. In both Fig. 5 and Fig. 6 the hinge 100 is shown in a partially assembled state. As can be seen in Figs 5 and 6, the reversable hinge 100 is configured such that the attachment member 140 connects to the opposite major side 121, 122 of the second hinge leaf 120 to the spacer 130. In some examples, the at least one apertures 125, 135 of the second hinge leaf 120 and spacer 130 are for receiving the at least one mounting pin 142, 143 of the attachment member 140. In some examples, the at least one apertures 125, 135 of the second hinge leaf 120 and spacer 130 are for receiving at least one threaded fastener which passes through an aperture 145 of the attachment member 140. In some examples, the first aperture 125 of the second hinge leaf 120 is for receiving the first mounting pin 142 and the second aperture 125 of the second hinge leaf 120 is for receiving the second mounting pin 143. The first aperture 135 of the spacer 130 is for receiving the first mounting pin 142 and the second aperture 135 of the spacer 130 is for receiving the second mounting pin 143. The first and second apertures 125, 135 of both the spacer 130 and second hinge leaf 120 may also be for receiving the threaded fasteners. In some, examples, when the spacer 130 and second hinge leaf 120 are connected the first aperture 135 of the spacer 130 is configured to substantially align with the first aperture 125 of the second hinge leaf 120, and the second aperture 135 of the spacer 130 is configured to substantially align with the second aperture 125 of the second hinge leaf 120. In the illustrated example, for the second hinge leaf 120 the first aperture 125 and second aperture 125 each comprise a first portion 126 for receiving the first mounting pin 142, 143 and a second portion 127 for receiving the at least one threaded fastener. The first portion 126 is narrower than the second portion 127. This provides the best fit for both the mounting pins 142, 143 and threaded fastener(s) which improves mounting and alignment. In the illustrated spacer 130 the first and second apertures 135 also comprises similar first and second portions 136, 137 which substantially align with the first and second portions 136, 137 of the apertures 125 of the second hinge leaf 120. To switch the hinge 100 between the left hand and right hand configurations: first, the attachment member 140 is disconnected from the second major side 122 of the second hinge leaf 120 and then the spacer 130 is disconnected from the first major side 121 of the second hinge leaf 120; next the positions of the attachment member 140 and spacer 130 are swapped, then the spacer 130 is connected to the second major side 122 of the second hinge leaf 120 and the attachment member 140 is connected to the first major side 121 of the second hinge leaf 120. This process allows for the orientation / configuration of the hinge 100 to be switched quickly and easily without the need to completely disassemble the hinge 100. In particular it does not require the hinge pin 160 to be removed and the second hinge leaf 120 to be flipped. This significantly speeds up instantiation of the hinge 100. In some examples the hinge 100 comprises a cover 150 for at least partially encasing the second hinge leaf 120. The cover 150 may also be for at least partially encasing the spacer 130, the attachment member 140 and / or the first hinge leaf 110. A first example of a cover 150 is shown in Fig. 1. The cover 150 is removable. In some examples the cover 150 may be detachably connected to the first major side 121 and the second major side 122 of the second hinge leaf 120. In some examples the cover 150 is configured such that it can only be removed from, or connected to, the hinge 100 when the hinge 100 is in an open position. This prevents the cover 150 being removed when the sash is closed, and so prevents access to any threaded fasteners when the sash is closed. This prevents disassembly of the hinge 100 and thus improves security. Fig. 7 shows a second example of a cover 750. The second example of a cover 750 is similar to the first example of a cover 150. A key difference being that for the second example of a cover 750, the cover 750 comprises a second example of a spacer 730 which may be similar to the first example of a spacer 130. The illustrated cover 750, comprises a wall 762, a chamber 764 for least partially encasing the second hinge leaf 120, an opening 766 for the second hinge leaf 120, and the spacer 730. In this example, the spacer 730 is positioned around the opening 766. The spacer 730 is configured to maintain a clearance between second hinge leaf 120 and the sash. In the illustrated example, the second example of a spacer 730 and the second example of a cover 750 are integrally formed. The spacer 730 may be considered to be a lip 730 of the cover 750, where the lip 730 has sufficient thickness to act as the spacer 730. In some examples, the first hinge leaf 110, hinge pin 160, second hinge leaf 120, spacer 130, 730 and attachment member 140 are separate components and are not integrally formed. The hinge 100 and its components may be comprised of any suitable materials. For example a plastic such as high density polyethylene. Where a structural feature has been described, it may be replaced by means for performing one or more of the functions of the structural feature whether that function or those functions are explicitly or implicitly described. The term ‘comprise’ is used in this document with an inclusive not an exclusive meaning. That is any reference to X comprising Y indicates that X may comprise only one Y or may comprise more than one Y. If it is intended to use ‘comprise’ with an exclusive meaning then it will be made clear in the context by referring to ‘comprising only one...’ or by using ‘consisting.’ In this description, the wording ‘connect’, ‘couple’ and ‘communication’ and their derivatives mean operationally connected / coupled / in communication. It should be appreciated that any number or combination of intervening components can exist (including no intervening components), i.e., to provide direct or indirect connection / coupling / communication. Any such intervening components can include hardware and / or software components. In this description, reference has been made to various examples. The description of features or functions in relation to an example indicates that those features or functions are present in that example. The use of the term ‘example’ or ‘for example’ or ‘can’ or ‘may’ in the text denotes, whether explicitly stated or not, that such features or functions are present in at least the described example, whether described as an example or not, and that they can be, but are not necessarily, present in some of or all other examples. Thus ‘example’, ‘for example’, ‘can’, or ‘may’ refers to a particular instance in a class of examples. A property of the instance can be a property of only that instance or a property of the class or a property of a sub-class of the class that includes some but not all the instances in the class. It is therefore implicitly disclosed that a feature described with reference to one example but not with reference to another example, can where possible be used in that other example as part of a working combination but does not necessarily have to be used in that other example. Although examples have been described in the preceding paragraphs with reference to various examples, it should be appreciated that modifications to the examples given can be made without departing from the scope of the claims. Features described in the preceding description may be used in combinations other than the combinations explicitly described above. Although functions have been described with reference to certain features, those functions may be performable by other features whether described or not. Although features have been described with reference to certain examples, those features may also be present in other examples whether described or not. The term ‘a’, ‘an’ or ‘the’ is used in this document with an inclusive not an exclusive meaning. That is any reference to X comprising a / an / the Y indicates that X may comprise only one Y or may comprise more than one Y unless the context clearly indicates the contrary. If it is intended to use ‘a’, ‘an’ or ‘the’ with an exclusive meaning then it will be made clear in the context. In some circumstances the use of ‘at least one’ or ‘one or more’ may be used to emphasis an inclusive meaning but the absence of these terms should not be taken to infer any exclusive meaning. The presence of a feature (or combination of features) in a claim is a reference to that feature or (combination of features) itself and to features that achieve substantially the same technical effect (equivalent features). The equivalent features include, for example, features that are variants and achieve substantially the same result in substantially the same way. The equivalent features include, for example, features that perform substantially the same function, in substantially the same way to achieve substantially the same result. In this description, reference has been made to various examples using adjectives or adjectival phrases to describe characteristics of the examples. Such a description of a characteristic in relation to an example indicates that the characteristic is present in some examples exactly as described and is present in other examples substantially as described. The above description describes some examples of the present disclosure however those of ordinary skill in the art will be aware of possible alternative structures and method features which offer equivalent functionality to the specific examples of such structures and features described herein above and which for the sake of brevity and clarity have been omitted from the above description. Nonetheless, the above description should be read as implicitly including reference to such alternative structures and method features which provide equivalent functionality unless such alternative structures or method features are explicitly excluded in the above description of the examples of the present disclosure. Whilst endeavoring in the foregoing specification to draw attention to those features believed to be of importance the Applicant may seek protection via the claims in respect of any patentable feature or combination of features hereinbefore referred to and / or shown in the drawings whether or not emphasis has been placed thereon. l / we claim:
