Description

TECHNOLOGICAL FIELD Examples of the disclosure relate to a support aid. Some relate to a support frame in the form of a toilet frame. BACKGROUND Support aids are widely used by the elderly or handicapped. One form of support frame is a toilet frame which generally has a U shape in plan view, with a front part which locates in front and below a toilet bowl, and two side parts which extend either side of the toilet and thereabove. A person can use the side parts to support themselves, and also when rising off a toilet seat. Such frames are very widely used. It is important that these frames are stable and secure. Such frames are however quite bulky in storage and transportation. This can be a particular problem where for instance only a single frame is required to be shipped or stored, and such personal use of items such as support frames is increasing.

DETAILED DESCRIPTION Examples of the disclosure relate to support aids. Fig. 1 illustrates an example support aid in the form of a toilet frame 100. The toilet frame 100 is for supporting a user of a toilet. The example toilet frame 100 comprises a first side frame 110, a second side frame 120, and a cross frame 130. The first side frame 110 is the left side frame in the example 100 of Fig. 1, and the second side frame 10 is the right side frame. The cross frame 130 is configured to couple the first side frame 110 to the second side frame 120. The toilet frame 100 further comprises a locking mechanism configured to selectively adjust the toilet frame between a first condition and a second condition. The locking mechanism could also be referred to as a lock configured to lock the first side frame 110 and the second side frame 120 in position relative to the cross frame 130 and unlock the first side frame 110 and the second side frame 120 from the cross frame such that the first side frame 110 and the second side frame 120 are movable relative to the cross frame 130. In the first condition the first side frame 110 and the second side frame 120 are movable relative to the cross frame 130. In some examples, in the first condition the first side frame 110 and the second side frame 120 are rotatable about the cross frame 130, and / or the first side frame 110 and the second side frame 120 are detachable from the cross frame 130. In the second condition the first side frame 110 and the second side frame 120 are locked in position relative to the cross frame 130. The first condition could also be referred to as an unlocked condition and the second condition could be referred to as a locked condition. Fig 1. Illustrates the example toilet frame 100 in the second condition. In other words, the first side frame 110 and the second side frame 120 are locked in position relative to the cross frame 130 in the example of Fig. 1. The second condition (i.e., a locked condition) provides a stable support for a user of a toilet. Fig. 2 is an exploded view of the example toilet frame 100 of Fig. 1. The cross frame 130 is configured to couple the first side frame 110 to the second side frame 120. The cross frame 130 may extend substantially only within a single plane. The cross frame 130 comprises one or more elongate members, in the form of one or more tubes in this example. The cross frame 130 may be adjustable in length. The cross frame 130 in this example comprises first and second leg portions 131, 132, along with a cross bar 133. The first and second leg portions 131, 132 provide the first and second front legs of the toilet frame 100. The first and second leg portions 131, 132 may each comprise an elongate tube. The first and second leg portions 131, 132 may each be substantially upstanding tubular members. A foot 140 may be provided at the end of each of the first and second leg portions 131, 132. In the example of Figs. 1 and 2, the cross bar 133 of the cross frame 130 is configured to couple the firstand second leg portions 131, 132 of the cross frame 130. The cross bar 133 may be tubular. In this example, the cross bar 133 is substantially perpendicular to the first and second leg portions 131, 132. The cross bar 133 may be telescopic to permit width adjustment of the toilet frame 100. In this example, a break is provided in the cross bar 133, to provide first and second parts 134, 135 of the cross bar 133. The first part 134 of the cross bar 133 comprises a larger diameter tube than the second part 135 to permit telescopic insertion of the second part 135 into the first part 134. A plurality of spaced apertures 136 are provided along the length of the second part 135 and an aperture 137 is provided in the first part 134 to permit the required telescopic mounting. A pin 150 is provided for insertion into the apertures 136, 137 of the first and second parts 134, 135 of the cross bar 133 to retain the cross bar 133 at a required length, and hence the toilet frame 100 at a required width. The pin 150 may be in the form of a clip, such as an e clip. The clip may comprise a resilient c-shaped collar configure to clip onto a tube. The clip may further comprise an elongate pin portion extending from an internal surface of the collar, the pin portion being for insertion into an aperture. The collar may be made from a plastics material. The pin portion may be made from metal. In some examples, such as the example of Figs. 1 &2, the cross frame 130 comprises a further cross bar 138. The further cross bar 138 may be substantially the same as the cross bar 133, but is spaced from the cross bar 133 and is substantially parallel to the cross bar 133. In other examples, the cross frame 130 might not include a further cross bar 138. The first side frame 110 comprises one or more elongate members, in the form of one or more tubes in this example, and the first side frame 110 and the cross frame 130 are telescopically engageable together. The end of the tube of the first side frame 110 may have a larger diameter than the end of the tube of the first leg portion 131 of the cross frame 130 to permit telescopic insertion of the first leg portion 131 of the cross frame 130 into the tube of the first side frame 110. The side frame 110 may be height adjustable. In the examples of Figs. 1 &2, the first side frame 110 comprises a handle section 112 and a rear leg section 113. The rear leg section 113 provides the third leg of the toilet frame 100. The handle section 112 comprises a length of tube in a substantially n-shape in this example. The front of the substantially n-shaped length of tube of the handle section 112 is configured to receive the first leg portion 131 of the cross frame 130 for telescopic insertion in this example. A handle 170 may be provided on the handle section 112. The rear leg section 113 comprises a length of tube with a foot 140 at a lower end. The rear leg section 113 is telescopically locatable in the handle section 112, in the rear of the substantially n-shaped length of tube. In this example, the handle section 112 of the first side frame 110 comprises a larger diameter tube than the rear leg section 113 to permit telescopic insertion of the rear leg section 113 into the handle section 112. The rear leg section 113 of the first side frame 110 may include a plurality of spaced apertures 115 to permit the required telescopic mounting to the rear side of the handle section 112 using a pin 150. The handle section 112 includes a rear aperture 117 configured to align with the apertures 115 of the rear leg section when the rear leg section 113 is telescopically engaged with the handle section 112. A pin 150 is provided for insertion into the rear aperture 117 of the handle section 112 and the spaced apertures 115 of the rear leg section 113 of the first side frame 110 to retain the first side frame 110 at a required height. The pin 150 may be in the form of a clip, such as an e clip. The clip may comprise a resilient c-shaped collar configure to clip onto a tube. The clip may further comprise an elongate pin portion extending from an internal surface of the collar, the pin portion being for insertion into an aperture. The collar may be made from a plastics material. The pin portion may be made from metal. In this example, the second side frame 120 also includes a handle section 122 and a rear leg section 124, which each include substantially the same features as the handle section 112 and a rear leg section 113 respectively of the first side frame 110. The rear leg section 124 of the second side frame 120 provides the leg of the toilet frame 100. In some examples, the first side frame 110, the second side frame 120 and / or the cross frame 130 are substantially cylindrical. The first side frame 110, the second side frame 120 and / or the cross frame 130 may be made from one or more tubes. The tubes of the first side frame 110, the second side frame 120 and / or the cross frame 130 may be made from metal. In the example of Fig. 1, the toilet frame 100 is provided in a support configuration. The first side frame 110, the second side frame 120 and the cross frame 130 are substantially planar in this example (i.e., each of the first side frame 110 and the second side frame 120 extend substantially only within a single plane). In the support configuration, the first side frame 110 and the second side frame 120 may extend substantially perpendicularly to the cross frame 130. The cross bar 133 of the toilet frame 130 may be substantially horizontal (i.e., parallel to ground) in the support configuration. The first side frame 110 and the second side frame 120 may be substantially parallel to one another in the support configuration. The example toilet frame 100 includes a locking mechanism for selectively adjusting the toilet frame 100 between the first and second condition. In the example of Figs. 1 and 2, the locking mechanism comprises an adjustable grip 160. The adjustable grip 160 is threadably adjustable to selectively secure (i.e., lock) the first side frame 110 to the cross frame 130. The adjustable grip 160 is threadably adjustable between engaged and disengaged positions. In the engaged position, the adjustable grip 160 secures (i.e., locks) the first side frame 110 to the cross frame 130. In the engaged position, the adjustable grip 160 inhibits both telescopic and rotational movement of the first side frame 110 relative to the cross frame 130, but the adjustable grip 160 is particularly effective at inhibiting longitudinal movement of the first side frame 110 relative to the cross frame 130. The toilet frame 100 may be in the second condition when the adjustable grip 160 is in the engaged position. In the disengaged position, the adjustable grip 160 permits movement of the first side frame 110 relative to the cross frame 130. The toilet frame 110 may be in the first condition when the adjustable grip 160 is in the disengaged position. In the first condition, the first side frame 110 may be able to rotate relative to the cross frame 130 and the first side frame 110 may be detachable from the cross frame 130. An example adjustable grip 160 is shown in further detail in Figs. 3B and 4. Fig. 3B is a cross-sectional view along the line K-K of Fig. 3A. Fig. 3A shows a front view of the example toilet frame 100 of Figs. 1 &2. Fig. 4 shows an exploded perspective view of the adjustable grip 160. As shown in Figs. 3B and 4, the adjustable grip 160 includes an inner portion 162 and an outer portion 164. The inner portion 162 and outer portion 164 may each be substantially cylindrical. The inner portion 162 includes an insert 166 for insertion into the end of the tube of the handle section 112 of the first side frame 110. The insert 166 includes an outer projection 167 configured to couple to a grip hole 111 in the tube of the handle section 112 of the first side frame 110, to secure the inner portion 162 to the first side frame 110. The outer portion 164 includes a through hole for locating the inner portion 162. In this example, the outer portion 164 includes an internal thread 165 on the internal surface of the through hole. The inner portion 162 of the example adjustable grip 160 may comprise an external thread 163 which is configured to threadably engage with the internal thread 165 of the outer portion 164, to permit positional adjustment of the inner portion 162 relative to the outer portion 164 between engaged and disengaged positions. In the engaged position the adjustable grip 160 is urged against the cross frame 130 when the cross frame 130 and the first side frame 110 are telescopically engaged. The outer portion 164 may comprise a retainer configured to prevent the outer portion 164 from advancing beyond a predetermined position on the external thread 163 of the inner portion 162, thereby restricting the outer portion 164 from travelling off the end of the external thread 163 (i.e., the outer portion 164 is a captive nut). The inner portion 164 may comprise a grip portion 168 including a plurality of flexible arms. The outer portion 164 may comprise an abutment surface 169 configured to urge the grip portion 168 radially inwardly when the adjustable grip 160 is in the engaged position. The abutment surface 169 may be a tapered portion of the outer portion 164. The grip portion 168 is configured to grip against the first leg portion 131 when the adjustable grip 160 is in the engaged position (i.e., when the cross frame 130 and the first side frame 110 are telescopically engaged and when the grip portion 168 is urged radially inwardly by the abutment surface 169). A further adjustable grip 160, which is substantially the same as the adjustable grip 160 in this example, is threadably adjustable to selectively secure the second side frame 120 to the cross frame 130. Additionally, or alternatively to the adjustable grip 160, the locking mechanism for selectively adjusting the toilet frame 100 between the first and second condition may comprise a pin lock. The pin lock is adjustable to selectively secure (i.e., lock) the first side frame 110 to the cross frame 130. The pin lock includes one or more locking apertures 118 for receiving a pin 150 in the first side frame 110 and one or more locking apertures 138 for receiving a pin 150 in the cross frame 130. As described previously, the cross frame 130 and the first side frame 110 may be telescopically engageable. The one or more locking apertures 118 in the first side frame 110 are configured to align with the one or more locking apertures 138 in the cross frame 130 when the cross frame 130 and the first side frame 110 are telescopically engaged. The pin lock further comprises the pin 150 in some examples. The pin 150 may be in the form of a clip, such as an e clip. The clip may comprise a resilient c-shaped collar configure to clip onto a tube. The clip may further comprise an elongate pin portion extending from an internal surface of the collar, the pin portion being for insertion into an aperture. The collar may be made from a plastics material. The pin portion may be made from metal. In some examples, the one or more locking apertures 118 in the first side frame 110 are non-circular apertures. The one or more locking apertures 118 in the first side frame 110 are tapered in some examples (i.e., the walls of the one or more locking apertures are tapered). The cross-section (i.e., the shape) of the entry and / or exit of the one or more locking apertures 118 may be elongate. The length dimension of the cross-section of the one or more elongate locking apertures 118 defines a first axis 50, shown in Figs. 5B to 6B. In use, the first axis 50 may be closer in orientation to the vertical axis than the horizontal axis (i.e., ground). One or more of the walls of the one or more locking apertures 118 may taper away from the first axis 50. In other words, the width of the cross-section of the one or more locking apertures 118 gradually varies from a relatively narrow portion for locating the pin to a relatively wide portion for locating the pin. A tapered locking aperture 118 is illustrated in Fig. 5B. Fig. 5B is a magnified view in the circle C of Fig. 5A. Fig. 5A shows a front view of the example toilet frame 100 of Figs. 1 &2, with the pin 150 disengaged from the locking aperture 118 in the first side frame 110. As shown in Fig. 5B, the locking aperture 118 may be substantially ovoid in shape, as shown for example in Fig. 5B. In other words, the cross-section of the entrance and / or the exit of the locking aperture 118 may be substantially ovoid in shape. An ovoid is an oval with only one axis of symmetry, which in the example of Figs. 6A and 6B is the first axis 50. In some examples, the one or more locking apertures 138 in the cross frame 130 are non-circular apertures. The one or more locking apertures 138 in the cross frame 130 are tapered in some examples (i.e., the walls of the one or more locking apertures are tapered). The cross-section (i.e., the shape) of the entry and / or exit of the one or more locking apertures 138 may be elongate and the length dimension of the cross-section of the one or more locking apertures 138 defines a second axis 60. The second axis 60 is parallel to the first axis 50 in this example, when the first side frame 110 and the cross frame 130 are telescopically engaged. One or more of the walls of the one or more locking apertures 138 may taper away from the second axis 60. In other words, the width of the cross-section of the one or more locking apertures 138 gradually varies from a relatively narrow portion for locating the pin to a relatively wide portion for locating the pin. The locking aperture 138 may be substantially ovoid (i.e., substantially an oval with only one axis of symmetry) in shape. In other words, the cross-section of the entry and / or exit of the locking aperture 138 may be substantially ovoid in shape. Figs. 6A and 6B illustrate a locking aperture 118 on the first side frame 110 and a locking aperture 138 in the cross frame 130 with a pin 150 inserted therethrough, when the cross frame 130 and the first side frame 110 are telescopically engaged. The broken lines of the locking aperture 138 in the cross frame 130 illustrate the portions of the locking aperture 138 in the cross frame 130 that are hidden behind the first side frame 110. In this example, the locking aperture 118 in the first side frame 110 and the locking aperture 138 in the cross frame 130 have opposing tapering (i.e., the walls of the locking aperture 118 in the first side frame 110 taper / narrow in an opposite direction to the locking aperture 138 in the cross frame 130), when the cross frame 130 and the first side frame 110 are telescopically engaged. In other words, when the cross frame 130 and the first side frame 110 are telescopically engaged, the relatively narrow portion of the locking aperture 118 in the first side frame 110 is at an opposite end of the elongate locking aperture 118 to the relatively narrow portion of the elongate locking aperture 138 in the cross frame 130, when the cross frame 130 and the first side frame 110 are telescopically engaged. For instance, in this example, the substantially ovoid locking aperture 118 in the first side frame 110 is arranged such that it is substantially oppositely oriented to the substantially ovoid locking aperture 138 in the cross frame 130, when the cross frame 130 and the first side frame 110 are telescopically engaged. Fig 6A illustrates the locking apertures 118, 138 and pin 150 when no downward pressure is applied to the first side frame 110. The pin 150 therefore sits at a relatively wide portion of each of the locking apertures 118, 138, which results in weak engagement between the pin 150, the first side frame 110 and the cross frame 130. Fig. 6B illustrates the apertures 118, 138 and pin 150 when downward pressure is applied to the first side frame 110 by a user. For instance, downward pressure may be applied to the handle 170 by a user. When downward pressure is applied, the pin 150 is forced to a relatively narrow portion of the locking apertures 118,138 (i.e., the locking apertures 118, 138 pinch / wedge the pin 150), which results in stronger engagement between the pin 150, the first side frame 110 and the cross frame 130. Therefore, when downward pressure is applied by a user, the engagement between the first side frame 110 and the cross frame 130 is substantially increased, which in turn minimises rotational and longitudinal movement of the first side frame 110 relative to the cross frame 130, thereby providing a much sturdier support aid. In some examples, once downward pressure has been applied by a user, the adjustable grip 160 can be moved to the engaged position to secure the pin 150 in the narrow portion of the of the locking apertures 118, 138, thereby further preventing movement of the first side frame 110 relative to the cross frame 130. The pin lock and adjustable grip 160 can therefore work synergistically to provide a sturdier support aid. In the example toilet frame 100 shown in the Figures, the one or more locking apertures 118 in the first side frame 110 are provided in the handle section 112 of the first side frame 110. The one or more locking apertures 138 in the cross frame 130 are provided in the first leg portion 131 of the cross frame 130. The first leg portion 131 is telescopically locatable in an end of the handle section 112, and the first leg portion 131 includes a plurality of spaced locking apertures 138 in this example, to permit the required telescopic mounting using the pin 150. The handle section 112 is rotatable about the first leg portion 131 when the toilet frame 100 is in the first condition. As shown in Figs. 1 and 2, the pin lock may further include a side aperture 119 in the first side frame 110 for insertion of a pin 150. The side aperture 119 may be provided substantially 90 degrees around the longitudinal axis of the elongate member of the first side frame 110 relative to the one or more locking apertures 118 in the first side frame 110. The side aperture 119 can be used to lock the toilet frame 100 in a folded configuration, as described later in the description. Figs. 7A and 7B show front and side views of the example toilet frame 110 of Figs. 1 &2 at a first telescopic mounting position. Figs 8A and 8B show front and side views of the example toilet frame of Figs. 1 &2 at a second higher and wider telescopic mounting position. In some examples, the toilet frame 100 comprises a handle 170. An example handle 170 is shown in further detail in Figs. 9B and 10. Fig. 9B is a cross-sectional view along the line l-l of Fig. 9A. Fig. 9A shows a rear view of the example toilet frame 100 of Figs. 1 &2. Fig. 10 is a perspective view of the underside of the handle 170. The first side frame 110 includes a plurality of mounting holes 116 for mounting the handle 170 to the first side frame 110. In this example, the mounting holes 116 are provided in the handle section 112 of the first side frame 110. As shown in Figs. 9B and 10, the handle 170 comprises a plurality of bosses 172 for insertion into the mounting holes 116 of the first side frame 110. One or more of the bosses 172 may include one or more crush ribs 174 configured to plastically deform against the respective mounting hole 116 when the respective boss 172 is inserted therein, to secure the handle 170 against the first side frame 110. Additionally, or alternatively, one or more of the bosses 172 may comprise one or more resilient projections 176. The one or more resilient projections 176 extend radially outwardly from the boss 172 to secure the boss 172 in the respective mounting hole 116 and are configured to resiliently deflect during insertion into the mounting hole 116 to permit insertion of the boss 172 into the hole 116. The second side frame 120 may include substantially the same features as the first side frame 110 described above. The second side frame 120 may include substantially the same one or more locking apertures, side aperture, mounting holes and / or rear aperture as the first side frame 110, as shown in the example toilet frame 100 of the Figures. A further handle 170 may be mounted to the second side frame 120. Furthermore, the second leg portion 132 of the cross frame 130 may include substantially the same features as the first leg portion 131 of the cross frame 130. Substantially the same one or more locking apertures may be provided in the second leg portion 132 as the first leg portion 131 of the cross frame 130, as shown in the example toilet frame 100 of the Figures. These features of the second side frame 120 and the second leg portion 132 are not labelled in the Figures for clarity. Figs 11A and 11B illustrate front and side views of the example toilet frame 100 in a folded configuration. In the folded configuration, the first side frame 110 and the second side frame 120 may be substantially parallel to the cross frame 130, as shown in Figs. 11A and 11B. The term ‘substantially parallel’ has a tolerance associated therewith. The tolerance may be 15 degrees, 10 degrees or 5 degrees. Furthermore, in the folded configuration, the toilet frame 110 may extend substantially only within a single plane (i.e., the first side frame 110, the second side frame 120 and the cross frame 130 are substantially in the same plane, as shown in Figs. 11A and 11B). Preferably, as shown in Figs 11A and 11B, in the folded configuration the first side frame 110 is located on an opposite side of the cross frame 130 to the second side frame 120 (i.e., the cross frame 130 is sandwiched between the first side frame 110 and the second side frame 120 in the folded configuration). This z-folded arrangement with the first side frame 110 being located on an opposite side of the cross frame 130 to the second side frame 120 has been found to provide an improved packing size, as interference between the first side frame and second side frame is minimised. Fig. 1 illustrates the example toilet frame 100 in a support configuration. In the support configuration, the toilet frame may have a u-shape in plan view. In the support configuration, the first side frame 110 and the second side frame 120 may each extend in a plane that is substantially perpendicular to the plane of the cross frame 130. When the toilet frame 100 is in the first (i.e., unlocked) condition, the toilet frame 100 is able to transition between the folded configuration and the support configuration. When the toilet frame 100 is in the second (i.e., locked) condition, the toilet frame 100 is locked in the folded configuration or the support configuration. In use, the toilet frame 100 can be converted from the support configuration to the folded configuration using the following steps. Starting from the second (i.e., locked) condition, the adjustable grips 160 at the front of the first and second side frames 110, 120 can be rotated to the disengaged position. The pins 150 in the locking apertures 118, 138 in the first side frame 110, the second side frame, and the cross frame 130 can be removed by a user. Once the pins 150 have been removed from the locking apertures 118, 138 and the adjustable grips 160 have been rotated to the disengaged position, the first and second side frames 110, 120 are movable relative to the cross frame 130. In particular, in this example once the pins 150 have been removed from the locking apertures 118,138, the first and second side frames 110, 120 are rotatable relative to the cross frame 130. The toilet frame 100 is then in the first (i.e., unlocked) condition. Once in the first condition, the second side frame 120 may be rotated substantially 90 degrees clockwise about the second leg portion 132 towards the cross frame 130 and the first side frame 110 may be rotated substantially 270 degrees clockwise about the first leg portion 131 to convert the toilet frame 100 to the folded configuration. Alternatively, the second side frame 120 may be rotated substantially 270 degrees anticlockwise about the second leg portion 132 and the first side frame 110 may be rotated substantially 90 degrees anticlockwise towards the cross frame 130 about the first leg portion 131 to convert the toilet frame 100 to the folded configuration. To secure the toilet frame 100 in the folded configuration, the toilet frame 100 can be returned to the second (i.e., locked) condition. A pin 150 can be inserted into the side aperture 119 of the first side frame 110 and the locking apertures 138 in the cross frame 130, to secure the first side frame 110 relative to the cross frame 130. A pin 150 can be inserted into the side aperture of the second frame 120 in substantially the same way. Optionally, the adjustable grips 160 at the front of the first and second side frames 110, 120 may be rotated to the engaged position to further secure the first and second side frames 110, 120 relative to the cross frame 130. The toilet frame 100 is then in the second (i.e., locked) condition and in the folded configuration. In particular, in this example once the pins 150 have been inserted into the side apertures 119 and the locking apertures 138 in the cross frame 130, the first and second side frames 110, 120 are not rotatable relative to the cross frame 130. In use, the toilet frame 100 can be converted from the folded configuration to the support configuration using the following steps. Starting from the second (i.e., locked) condition, the pins 150 in the side apertures 119 and the locking apertures 138 in the cross frame 130 can be removed by a user. The adjustable grips 160 of the first and second side frames 110, 120 can be rotated to the disengaged position. Once the pins 150 have been removed from the side apertures 119 and the locking apertures 138 and the adjustable grips 160 have been rotated to the disengaged position, the first and second side frames 110, 120 are movable relative to the cross frame 130. In particular, in this example once the pins 150 have been removed from the side apertures 119 and the locking apertures 138, the first and second side frames 110, 120 are rotatable relative to the cross frame 130. The toilet frame 100 is then in the first (i.e., unlocked) condition. Once in the first condition, the second side frame 120 may be rotated substantially 90 degrees anticlockwise about the second leg portion 132 away from the cross frame 130 and the first side frame 110 may be rotated substantially 270 degrees anticlockwise about the first leg portion 131 to convert the toilet frame 100 to the support configuration. Alternatively, the second side frame 120 may be rotated substantially 270 degrees anticlockwise about the second leg portion 132 and the first side frame 110 may be rotated substantially 90 degrees anticlockwise about the first leg portion 131 to convert the toilet frame 100 to the support configuration. To secure the toilet frame 100 in the support configuration, the toilet frame 100 can be returned to the second (i.e., locked) condition. Pins 150 can be inserted into the locking apertures 118, 138 in the first side frame 110, the second side frame, and the cross frame 130, to secure the first side frame 110 relative to the cross frame 130. To further secure the first side frame 110 relative to the cross frame 130, downward pressure can be applied by a user to the first and second side frames 110, 120 to force the pins to a relatively narrow portion of the locking apertures 118, 138. The adjustable grip 160 can then be moved to the engaged position to secure the pin 150 in the narrow portion of the of the locking apertures 118, 138. The toilet frame 100 is then in the second (i.e., locked) condition and in the support configuration. In particular, in this example once the pins 150 have been inserted into locking apertures 118, 138, the firstand second side frames 110, 120 are not rotatable relative to the cross frame 130. Examples of the disclosure include other types of support frame for supporting a person, in addition to toilet frames. For example, a support frame in the form of a rollator or a walker (i.e., a walking frame) may be provided. The walker or rollator may be substantially the same as the example toilet frame 100 described herein, but some or all of the feet 140 may be replaced with wheels. Examples of the disclosure also include other types of support aid for supporting a person, such as crutches, canes, ski poles or walking poles. The support aids may include first and second telescopically engageable elongate members (such as the tubes of a crutch), which include the pin lock described herein in relation to Figs. 5B, 6A and 6B. The pin lock can telescopically mount the first elongate member to the second elongate member and provide secure engagement between the first and second elongate members when pressure is applied by a user. The pin lock may secure the first elongate member of the support aid to the second elongate member of the support aid in the same manner as the first cross frame 110 of the toilet frame 100 is secured to the cross frame 130 of the toilet frame 100 by the pin lock, in particular as described in relation to Figs. 5B, 6A and 6B. Indeed, the first cross frame 110 of the toilet frame 100 and the cross frame 130 of the toilet frame 100 are examples of first and second elongate members respectively of a support aid. The support aid may further include one or more of the adjustable grips 160 described herein to further secure the elongate members in position. The first and / or the second elongate member may comprise one or more tubes. There is thus described a support aid with a number of advantages as described above and below. The support aid provides a stable platform for a user when in the support configuration, whilst also being readily transportable. The support aid is foldable to a substantially flat folded configuration, to facilitate efficient transport and shipping of the support aid. The pin lock provides improved stability whilst pressure is applied to the support aid by a user. The adjustable grip 160 can retain the first side frame 110 in position relative to the cross frame 130. The adjustable grip 160 can also assist in retaining the pin 150 in position once the locking apertures 118, 138 have pinched / wedged the pin 150, which provides a more stable support aid. The support aid can be adjusted to various heights and / or widths to suit a variety of users and environments. 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. 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. For instance, the locking mechanism of the support aid may include only a lock pin or the locking mechanism may include only an adjustable grip. The tubes may be replaced with non-cylindrical hollow elongate members. The side frames could be formed from a single part. The first and second leg portions 131, 132 may be wider than the handle sections 112, 122 of the first and second side frames 110, 120, such that the handle sections 112, 122 are telescopically insertable into the first and second leg portions 131, 132. 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. The description of a feature, such as an apparatus or a component of an apparatus, configured to perform a function, or for performing a function, should additionally be considered to also disclose a method of performing that function. For example, description of an apparatus configured to perform one or more actions, or for performing one or more actions, should additionally be considered to disclose a method of performing those one or more actions with or without the apparatus. 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.
