Patent Description:
Objects such as pipes are often hung from one end of rod, which could for instance be a threaded rod. The other end of the threaded rod may be fastened to a wall or a ceiling to enable the rod to support the pipe.

To hang a pipe from a threaded rod, a section of the pipe is received in a clamp with a threaded hole for receiving the end of the threaded rod. The clamp comprises two opposing halves which encircle the pipe, the two opposing halves being secured together using two bolts or screws on opposing sides of the clamp. These pipe hanging assemblies involve multiple components and fasteners, and thus these assemblies are time consuming and inefficient. Furthermore, the multiple fasteners used provide multiple weak points in the assembly, which increases the possibility of the assembly failing under load.

<CIT> discloses a pipe hanger arranged to be positioned about a pipe to be suspended. The pipe hanger can be moved to a closed position and engaged upon a supporting rod so as to carry the pipe. The hanger takes the form of an elongated band the ends of which are brought into proximity to one another by bending the band into a general oval shape. The ends of the band are formed in configurations registered with the thread pattern of the support rod when engaged thereagainst and a cylindrical ferrule is moved downwardly over the ends of the band so as to move the same into forceful engagement with the threaded supporting rod. An upstanding tab on one of the ends of the band is then distorted by bending the same downwardly so as to hold the cylindrical ferrule in desired position in which the ends of the band remain in tight, non-slipping engagement with the threaded support rod.

According to various, but not necessarily all, embodiments there is provided an apparatus for supporting an object, the apparatus comprising: a support surface; a first retainer and a second retainer, the first retainer being for coupling at least in part by the support surface to the second retainer, or being coupled at least in part by the support surface to the second retainer, wherein at least one of the first and second retainers comprises a stop; a fastener, comprising: an outer part including an internal surface that comprises a threaded portion, wherein the internal surface of the outer part is an internal surface of a through hole extending through the outer part; and an inner part including an external thread arranged to enable the outer part to threadably rotate around the inner part, and at least one slot having a non-circular cross section in a plane perpendicular to the screw axis of the external thread, the at least one slot being shaped to receive the first and second retainers, such that the first and second retainers are rotatably fixed relative to the at least one slot and the stop prevents the retainers from exiting the at least one slot in a direction co-incident with or parallel to the screw axis.

The stop may be a distal stop. The at least one slot may be shaped to receive the first and second retainers together. The at least one slot may comprise at least two slots. A first slot may be shaped to receive the first retainer and a second slot may be shaped to receive the second retainer, such that the first retainer is rotatably fixed relative to the first slot and the stop prevents the first retainer from exiting the first slot in a direction co-incident with or parallel to the screw axis; and such that the second retainer is rotatably fixed relative to the second slot and the stop prevents the second retainer from exiting the second slot in a direction co-incident with or parallel to the screw axis.

The first slot may be parallel with the second slot. The first and second slots may both be through holes. The first and second slots may at least partially overlap in a direction parallel to the screw axis.

The at least one slot may comprise a dividing portion which divides the at least one slot such that it comprises a first portion that is shaped to receive the first retainer and a second portion that is shaped to receive the second retainer. The first portion may be parallel with the second portion. The first and second portions may both be through holes. The first and second portions may at least partially overlap in a direction parallel to the screw axis.

The stop may be formed by at least one kink in at least one of the first and second retainer. The stop may be formed by at least two kinks in at least one of the first and second retainer. The stop of the first retainer may be formed by at least one kink in the first retainer and the stop of the second retainer may be formed by at least one kink in the second retainer. The at least one kink is configured to be deformed by the at least one slot such that when the retainer comprising the at least one kink is located in the at least one slot, the at least one kink is straightened.

The first and second retainers may be substantially non-linear. The first and second retainers may each be at least one of curved, crimped, kinked, twisted, sawtooth shaped, and wave shaped. The at least one slot may be substantially non-linear. The at least one slot may be at least one of curved, crimped, kinked, twisted, sawtooth shaped, and wave shaped. Each of the at least two slots may be substantially non-linear. Each of the at least two slots may be at least one of curved, crimped, kinked, twisted, sawtooth shaped, and wave shaped.

<FIG> shows an example first apparatus <NUM> for supporting an object, along with a threaded rod <NUM>. In <FIG>, the first apparatus <NUM> is shown in an unassembled condition. <FIG> shows a magnified view of <FIG>. The first apparatus <NUM> is shown in an assembled condition in <FIG>. The first apparatus <NUM> includes first and second retainers <NUM>, <NUM>, a first support <NUM> including a first support surface, and a first fastener <NUM>. The first fastener <NUM> comprises an inner part <NUM> and an outer part <NUM>. In this example, the first apparatus <NUM> is for supporting a pipe from the threaded rod <NUM>.

The first support <NUM> can be considered an elongate member.

As shown best in <FIG>, the first and second retainers <NUM>, <NUM> together have a non-circular cross section. In this example, first and second retainers are both elongate, and the longitudinal cross section of each of the first and second retainers <NUM>, <NUM> is non-circular. As shown best in <FIG>, the longitudinal cross section of each of the first and second retainers <NUM>, <NUM> is substantially rectangular.

The first retainer <NUM> comprises a stop <NUM>. The stop <NUM> may be a distal stop <NUM>. The distal stop <NUM> is provided at a distal end of the first retainer <NUM>, and the distal stop <NUM> is wider than the adjacent portion of the first retainer <NUM>. In other words, the distal stop <NUM> extends to a greater extent than the adjacent portion of the first retainer <NUM> in a dimension perpendicular to the length dimension of the first retainer <NUM>. In this example, the distal stop <NUM> is formed from a folded section of the retainer <NUM>. The distal end of the retainer <NUM> may be folded <NUM>° to form the distal stop <NUM>, such that the distal stop <NUM> is double the thickness of the adjacent portion of the retainer <NUM>. This is also illustrated in <FIG>, which show a cross sectional view of the retainers <NUM>, <NUM>. In this particular example, the first and second retainers <NUM>, <NUM> are similar, with each comprising a stop <NUM>, <NUM>.

The first retainer <NUM> is coupled at least in part by the first support surface to the second retainer <NUM>. The first support <NUM> comprises the first support surface for supporting an object. The first support <NUM> of <FIG> is annular in shape (and arranged to encircle an object such as a pipe), but may be a different shape in other examples. In this example, the first support surface is provided by an inner surface of the annular shaped first support <NUM>.

In this example of <FIG>, the first and second retainers <NUM>, <NUM> are integrally formed with the first support <NUM>. The first support <NUM> and the retainers <NUM>, <NUM> may be formed from a single band for encircling the object. The band may be a metal band, such as a steel band. The band may have a substantially rectangular cross section. In this example, the band forms a ring for encircling a section of a pipe. In this example the ring is substantially circular, but in other examples the ring could be a different shape, such as rectangular or square to support a rectangular or square cross section pipe. As shown for instance in <FIG>, the first and second retainers <NUM>, <NUM> may extend outwardly from the first support <NUM>, and be formed from sections of the band which are bent outwardly from the ring.

As shown in <FIG>, the inner part <NUM> of the first fastener <NUM>, which may be in the form of a section of threaded bar, includes an external thread <NUM>. The external thread <NUM> is defined by a helix extending around the inner part <NUM>, and the axis extending through the centre of the helix defines a screw axis. In this example, the inner part <NUM> is a substantially cylindrical shape.

The inner part <NUM> further includes a slot <NUM> with a non-circular cross section in a plane perpendicular to the screw axis of the external thread <NUM>. The slot <NUM> is defined by walls. The slot <NUM> is shaped to receive the first and second retainers <NUM>, <NUM> together, such that the first and second retainers <NUM>, <NUM> are rotatably fixed relative to the slot <NUM>, when located therein. This is illustrated in <FIG>. In this example, the slot <NUM> is shaped to correspond to the combined longitudinal cross sections of the first and second retainers <NUM>, <NUM>, and vice versa. This means that when the first and second retainers <NUM>, <NUM> are rotated inside the slot <NUM>, the inner part <NUM> also rotates. In other words, the inner part <NUM> does not rotate relative to the first and second retainers <NUM>, <NUM> when both the first and second retainers <NUM>, <NUM> are inserted into the slot <NUM>. In some examples, the inner part <NUM> may include more than one slot.

In the example of <FIG>, the slot <NUM> is in the form of a through hole extending along the screw axis through the inner part <NUM>. The slot <NUM> has a substantially rectangular cross section in a plane perpendicular to the screw axis to locate the first and second retainers <NUM>, <NUM>, which have a corresponding combined rectangular longitudinal cross section. In other examples, the cross section of the slot <NUM> in a plane perpendicular to the screw axis of the slot <NUM> may be for instance a hexagon, a triangle, a square (i.e. a rectangle with all sides of equal length), an oval or any other non-circular shape to enable torque to be transferred to or from retainers with a corresponding longitudinal cross section. The non-circular shape may have at least one vertex.

The corresponding cross section of the slot <NUM> and the first and second retainers <NUM>, <NUM> combined means that torque can be transferred between the first and second retainers <NUM>, <NUM> and the slot <NUM>, with the first and second retainers <NUM>, <NUM> acting as a "internal spanner", which can cause or prevent rotation of the inner part <NUM>.

The distal stops <NUM>, <NUM> of the first and second retainers <NUM>, <NUM> prevent the retainers <NUM>, <NUM> from exiting the slot <NUM> in a direction co-incident with or parallel to the screw axis of the inner part <NUM>. The distal stops <NUM>, <NUM> of the first and second retainers <NUM>, <NUM> combined are wider than the slot <NUM>, such that the stops <NUM>, <NUM> are unable to pass through the slot <NUM> when the retainers <NUM>, <NUM> are located in the slot <NUM>. In other words, the distal stops <NUM>, <NUM> of the first and second retainers <NUM>, <NUM> combined extend to a greater extent than the slot <NUM> in a dimension perpendicular to the screw axis to prevent the retainers <NUM>, <NUM> from exiting the slot <NUM> in a direction co-incident with or parallel to the screw axis.

The slot <NUM> of the inner part <NUM> includes an elongate opening <NUM> extending parallel to the screw axis, which is configured to receive the first and second retainers <NUM>, <NUM> from a direction perpendicular to the screw axis of the external thread <NUM>. The elongate opening <NUM> is present in the surface comprising the external thread <NUM>. In this example, the elongate opening <NUM> of the inner part <NUM> is shaped to receive only one of the first and second retainers <NUM>, <NUM> at a time. Therefore, when the first and second retainers <NUM>, <NUM> are both in the slot <NUM>, the retainers <NUM>, <NUM> are more secure in the slot <NUM>, as the opening <NUM> is narrower than the combined width of the first and second retainers <NUM>, <NUM>. However, in other examples, the elongate opening <NUM> of the inner part <NUM> may be wider, and shaped to receive both the first and second retainers <NUM>, <NUM> simultaneously.

<FIG> show schematic cross-sectional views of the inner part <NUM> of the first fastener <NUM>, along with the first and second retainers <NUM>, <NUM>, in various stages of assembly. As shown in the example <FIG>, a recess <NUM> is provided in the side of the slot <NUM> of the inner part <NUM>, the recess being shaped to locate the distal stop <NUM> of the first retainer <NUM>. The recess <NUM> provides an abutment surface <NUM> to prevent the retainer <NUM> from exiting the slot <NUM> in a direction co-incident with or parallel to the screw axis. Furthermore, locating the distal stop <NUM> of the first retainer <NUM> in the recess prevents the stop <NUM> unfurling under excessive pressure. In this example a recess <NUM> is provided in both sides of the slot <NUM> to locate the distal stops <NUM>, <NUM> of the first and second retainers <NUM>, <NUM> respectively. In other examples, the slot <NUM> may not include a recess <NUM>, and the end surfaces (i.e. the outermost surfaces in a plane perpendicular to the screw axis) of the inner part <NUM> may act as the abutment surface.

As illustrated in <FIG>, the outer part <NUM>, which in this example is in the form of an internally threaded nut, includes an internal surface <NUM> with a threaded portion <NUM> for engaging with the external thread <NUM> of the inner part <NUM>. The internal surface <NUM> of the outer part <NUM> is also configured to threadably engage with the threaded rod <NUM>. The internal surface <NUM> of the outer part <NUM> is an internal surface of a through hole extending through the outer part <NUM>, and the threaded portion <NUM> of the internal surface <NUM> extends for substantially the majority of the length of the outer part <NUM>. The hole extending through the outer part <NUM> has a greater extent along the screw axis than the inner part <NUM>, such that the whole of the inner part <NUM> can be received within the hole of the outer part <NUM>. In this example, the internal surface <NUM> of the outer part <NUM> is substantially cylindrical.

The outer part <NUM> is configured to threadably rotate around the inner part <NUM> and the threaded rod <NUM>. Rotation of the outer part <NUM> on the inner part <NUM> and threaded rod <NUM> simultaneously causes the inner part <NUM> to be urged towards or away from the end of the longitudinal end of the threaded rod <NUM>.

The outer part <NUM> includes one or more planar surfaces <NUM> on its external surface to enable a spanner to be received thereon and rotate the outer part <NUM>. In the example shown in <FIG> six planar surfaces <NUM> are provided, and the external surface of the outer part <NUM> has a substantially hexagonal cross section.

<FIG> show cross sectional views of the first apparatus <NUM> in various stages of assembly, the first apparatus <NUM> being for supporting a pipe <NUM>. In this example the pipe <NUM> has a substantially circular cross section, and the ring of the band is substantially circular in shape.

As illustrated in <FIG>, in use, the first and second retainers <NUM>, <NUM> are located in the slot <NUM> of the inner part <NUM> of the first fastener <NUM>. The outer part <NUM> of the first fastener <NUM> is also threadably located on a threaded rod <NUM>. The inner part <NUM> is then located at the longitudinal end of the threaded rod <NUM>, and the outer part <NUM> is threadably rotated onto the inner part <NUM>, such that the outer part <NUM> is threadably engaged with both the inner part <NUM> and the threaded rod <NUM>. As illustrated in <FIG>, further rotation of the outer part <NUM> causes the inner part <NUM> to be urged towards the end of the threaded rod <NUM>, to cause tightening of the first support <NUM> and the first support surface around the pipe. Once assembled, the first support <NUM> is hung from the threaded rod <NUM>.

<FIG> shows the first support <NUM> of <FIG> and a second support <NUM> including a second support surface. A first retainer <NUM> extending from the second support <NUM> is for coupling at least in part by the second support surface to a second retainer <NUM> extending from the second support <NUM>. The second support <NUM> is similar to the first support <NUM>, but the second support <NUM> comprises separate first and second parts <NUM>, <NUM>. The first retainer <NUM> with a distal stop <NUM> extends from the first part <NUM> of the second support <NUM>, and the second retainer <NUM> (also with a distal stop <NUM>) extends from the second part <NUM>. In this example the first and second parts <NUM>, <NUM> are each substantially semi-circular in shape, and the second support surface is provided by the inner surface of each of the respective semi-circular parts.

A third retainer <NUM> with a distal stop (distal stop not labelled in <FIG>) extends from the first part <NUM> of the second support <NUM>. In this example the third retainer <NUM> is provided at an opposite end of the first part <NUM> to the first retainer <NUM>. A fourth retainer <NUM> with a distal stop extends from the second part <NUM> of the second support <NUM>. In this example the fourth retainer <NUM> is provided at an opposite end of the second part <NUM> to the second retainer <NUM>. <FIG> shows pairs of retainers <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM> adjacent to one another, and <FIG> shows the same, but with inner parts <NUM> of three of the first fasteners <NUM> mounted to each of the three pairs of retainers <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>.

<FIG> shows the first apparatus <NUM>, along with a second example apparatus <NUM> comprising the second support <NUM> and three of the first fasteners <NUM>, with the first and second apparatuses <NUM>, <NUM> being in an assembled condition. The three first fasteners <NUM> of the second apparatus <NUM> secure the second support <NUM> to the threaded rod <NUM> of <FIG> and <FIG>, secure the second support <NUM> to a further threaded rod <NUM>, and secure the first support <NUM> to the further threaded rod <NUM> to couple the first apparatus <NUM> to the further elongate rod <NUM>. As illustrated in <FIG>, the separate first and second parts <NUM>, <NUM> and the third and fourth retainers <NUM>, <NUM> enable objects such as pipes to be mounted above one another in a space.

<FIG> illustrate alternate first and second retainers <NUM>, <NUM> of a third apparatus for supporting an object. The third apparatus also includes a third support <NUM> and a second fastener. The third support <NUM> includes a third support surface which is similar to the first support surface of the first support <NUM>.

The alternate first and second retainers <NUM>, <NUM> are similar to the first and second retainers <NUM>, <NUM>, <NUM>, <NUM>. However, in this example the alternate second retainer <NUM> is longer than the alternate first retainer <NUM>, i.e. the elongate alternate second retainer <NUM> has a greater length dimension than the elongate alternate first retainer <NUM>. The alternate second retainer <NUM> may be at least twice the length of the alternate first retainer <NUM>. As illustrated in <FIG>, the alternate second retainer <NUM> can extend away from the alternate first retainer <NUM> to attach to, for instance, a beam, a wall or a ceiling, to hang the third support <NUM>, without requiring a threaded rod.

<FIG> show an inner part <NUM> of the second fastener. The inner part <NUM> of the second fastener is similar to the inner part <NUM> of the first fastener <NUM>, however only a single recess <NUM> is provided in the slot <NUM>. The recess <NUM> of the inner part <NUM> of the second fastener is shaped to locate the distal stop <NUM> of the alternate first retainer <NUM>, as illustrated in <FIG>.

The outer part of the second fastener is not shown in <FIG> (and thus the third apparatus, which includes the outer part of the second fastener is not fully shown in <FIG>), but the outer part of the second fastener could for instance be substantially the same as the outer part <NUM> of the first fastener <NUM>. The outer part <NUM> of the second fastener may be an object with an internal surface that comprises a threaded portion corresponding to the external threading <NUM> of the inner part <NUM> of the second fastener.

The distal stop <NUM> of the alternate first retainer <NUM> prevents the alternate first and second retainers <NUM>, <NUM> from exiting the slot <NUM> of the inner part <NUM> of the second fastener in a direction co-incident with or parallel to the screw axis of the inner part <NUM>. The alternate second retainer <NUM> and the distal stop <NUM> of the alternate first retainer <NUM> combined are wider than the slot <NUM>, such that the stop <NUM> is unable to pass through the slot <NUM> when the retainers <NUM>, <NUM> are located in the slot <NUM>. In other words, the alternate second retainer <NUM> and the distal stop <NUM> of the alternate first retainer <NUM> combined extend to a greater extent than the slot <NUM> in a dimension perpendicular to the screw axis to prevent the retainers <NUM>, <NUM> from exiting the slot <NUM> in a direction co-incident with or parallel to the screw axis.

The alternate second retainer <NUM> includes attachment means for use in attaching the alternate second retainer <NUM> to a fixing. In this example, the attachment means is a distal stop <NUM>. In other examples, the attachment means of the alternate second retainer <NUM> could for instance be a distal hook.

Furthermore, in this particular example, the third apparatus includes a third fastener, and the inner part <NUM> of the third fastener is shown in <FIG>. The third fastener is for securing the alternate second retainer <NUM> to a body, such as a beam, a wall or a ceiling. The inner part <NUM> of the third fastener is similar to the inner part <NUM> of the second fastener. However, the slot <NUM> of the inner part <NUM> of the third fastener is shaped to receive the alternate second retainer <NUM>, rather than the first and second retainers <NUM>, <NUM> together, such that the alternate second retainer <NUM> is rotatably fixed relative to the slot <NUM> when located therein. The slot <NUM> of the inner part <NUM> of the third fastener is narrower than the alternate first and second retainers <NUM>, <NUM> combined, and is therefore too small to receive both the alternate first and second retainers <NUM>, <NUM> together. A single recess <NUM> is provided in the slot <NUM>. The recess <NUM> of the inner part <NUM> of the third fastener is shaped to locate the distal stop <NUM> of the alternate second retainer <NUM>.

The outer part of the third fastener is not shown in <FIG>, but the outer part of the third fastener could for instance be substantially the same as the outer part <NUM> of the first fastener <NUM>. In other examples, the outer part of the third fastener could be a threaded hole in a wall, a ceiling, or a clamp. The outer part of the third fastener may be an object with an internal surface that comprises a threaded portion corresponding to the external threading <NUM> of the inner part <NUM> of the third fastener.

The distal stop <NUM> of the alternate second retainer <NUM> prevents the alternate second retainer <NUM> from exiting the slot <NUM> of the inner part <NUM> of the third fastener in a direction co-incident with or parallel to the screw axis of the inner part <NUM>. The distal stop <NUM> of the alternate second retainer <NUM> is wider than the slot <NUM> of the inner part <NUM> of the third fastener, such that the stop <NUM> is unable to pass through the slot <NUM> when the alternate second retainer <NUM> is located in the slot <NUM>. In other words, the distal stop <NUM> of the alternate second retainer <NUM> extends to a greater extent than the slot <NUM> of the inner part <NUM> of the third fastener in a dimension perpendicular to the screw axis to prevent the alternate second retainer <NUM> from exiting the slot <NUM> in a direction co-incident with or parallel to the screw axis.

In use, the third support <NUM> of the third apparatus is first located on an object, such as a pipe. The alternate first and second retainers <NUM>, <NUM> are then inserted into the slot <NUM> of the inner part <NUM> of the second fastener, as shown in <FIG>. The outer part (not shown) of the second fastener can then be threadably located onto the inner part <NUM> of the second fastener to secure the object in the third support <NUM>.

Subsequently, as illustrated in <FIG>, the alternate second retainer <NUM> can be inserted into the slot <NUM> of the inner part <NUM> of the third fastener. Finally, the inner part <NUM> of the third fastener may be threadably located into the outer part of the third fastener. As indicated, the outer part of the third fastener could be a threaded hole in a wall, a ceiling, or a clamp. Thus, in this example, the object can be hung from a wall, a ceiling, or a clamp without the use of a threaded rod.

<FIG> show an example of an inner part <NUM> for a fastener.

In examples, the inner part <NUM> can be used in any suitable fastener. For example, the inner part <NUM> can be used in any of the examples described herein. The inner part <NUM> can therefore form part of a first fastener <NUM>, second fastener and/or third fastener.

The inner part <NUM> shown in the example of <FIG> is similar to the inner part <NUM> shown in <FIG>, and comprises an external thread <NUM>, a slot <NUM>, a recess <NUM> and an elongate opening <NUM>.

However, in examples, one or more of the features of the inner part <NUM> of <FIG> can be changed and/or omitted. For example, the recess <NUM> and/or elongate opening <NUM> can be omitted.

The inner part <NUM> of <FIG> comprises a non-threaded portion <NUM> which extends from an end of the externally threaded portion along a direction substantially parallel with the screw axis of the external thread <NUM>.

In the example of <FIG> the non-threaded portion <NUM> extends from the end of the externally threaded portion that is opposite the end in which the recess <NUM> is located.

The non-threaded portion <NUM> can be considered an extended portion and/or a retaining portion.

The non-threaded portion <NUM> comprises the slot <NUM> and elongate opening <NUM>. Accordingly, in the example of <FIG> the slot <NUM> and elongate opening <NUM> run along the length of the inner part <NUM>.

The non-threaded portion <NUM> has a non-circular cross section in a plane perpendicular to the screw axis of the external thread <NUM>.

The non-threaded portion <NUM> comprises an outer surface <NUM>. The outer surface <NUM> can have any suitable form. In examples, the outer surface <NUM> can be configured to fit into and/or cooperate with an intermediate or anti-twist part. See, for example, <FIG> and <FIG>.

In the example of <FIG> the outer surface of the non-threaded portion <NUM> comprises two substantially flat, rectangular portions either side of the elongate opening <NUM> which are adjacent to larger, substantially flat rectangular portions extending substantially parallel to the slot <NUM>. There is also a curved portion extending between the two larger, substantially flat rectangular portions.

The curvature of the curved portion substantially matches and/or follows the curvature of the external thread <NUM>.

A front view of the inner part <NUM> is shown in the left image of <FIG>, a side view of the inner part <NUM> is shown in the central image of <FIG> and a top view is shown in the right image of <FIG>.

<FIG> shows first and second retainers <NUM>, <NUM> located in the slot <NUM> of the inner part <NUM>, with the distal stops <NUM>, <NUM> (not labelled in the example of <FIG>) located in the recess <NUM> of the inner part <NUM>.

It can be seen in <FIG> that the non-threaded portion <NUM> extends along the first and second retainers <NUM>, <NUM> to an area where the first and second retainers <NUM>, <NUM> meet the first support <NUM>, or elongate member.

In the example of <FIG> the two larger, substantially flat rectangular portions of the non-threaded portion <NUM> are substantially parallel with the first and second retainers <NUM>, <NUM> when the first and second retainers <NUM>, <NUM> are located in the slot <NUM>.

The external thread <NUM> of the inner part <NUM> of <FIG> has a non-circular cross section in a plane perpendicular to the screw axis of the external thread <NUM>.

In examples, the external thread <NUM>, and therefore the exterior surface of the inner part <NUM>, can be considered to be configured and/or shaped to cooperate with and/or allow the inner part <NUM> to fit within a through hole of an intermediate part. See, for example, <FIG> and <FIG>.

The external thread <NUM>, or the outer surface, of the inner part <NUM> may comprise a number of flattened portions <NUM>. In the example of <FIG> the external thread <NUM>, or the external surface, of the inner part <NUM> has two flattened portions <NUM> opposite one another.

In the example of <FIG> the elongate opening <NUM> can be considered the front of the inner part <NUM> and the flattened portions <NUM> are located on the sides of the inner part <NUM>, relative to the elongate opening <NUM>.

The flattened portions <NUM> are substantially parallel with the slot <NUM> of the inner part <NUM>.

It can be seen in <FIG> that the inner part <NUM> extends along the first and second retainers <NUM>, <NUM> to an area where the first and second retainers <NUM>, <NUM> meet the first support <NUM>, or elongate member.

In examples, the inner part <NUM> of <FIG> can be considered an extended inner part <NUM>.

In the example of <FIG> the flattened portions <NUM> of the external thread <NUM> are substantially parallel with the first and second retainers <NUM>, <NUM> when the first and second retainers <NUM>, <NUM> are located in the slot <NUM>.

<FIG> show an example of an intermediate part <NUM>.

The left image of <FIG> shows an upper perspective view of the intermediate part <NUM> and the right image of <FIG> shows a lower perspective view of the intermediate part <NUM>.

The left image of <FIG> shows a top view of the intermediate part <NUM>, the central image of <FIG> shows a front view of the intermediate part <NUM> and the right image of <FIG> shows a side view of the intermediate part <NUM>.

The intermediate part <NUM> can be used and/or can form part of any suitable apparatus. For example, the intermediate part <NUM> can form part of an apparatus as described herein.

The intermediate part <NUM> can be considered a spacer and/or an anti-twist part and/or collar.

The intermediate part <NUM> can have any suitable size and/or shape and/or form to cooperate with one or more other elements of an apparatus as described herein to stabilise and/or prevent twisting in the apparatus in use. For example, the intermediate part <NUM> can be configured to cooperate with an inner part <NUM>, <NUM> of <FIG> and/or 9A to 9C and/or with the first support <NUM> to stabilise and/or prevent twisting of the first and second retainers <NUM>, <NUM> and/or first support <NUM> in use.

In the example of <FIG>, the intermediate part <NUM> has the form of a tube or collar and comprises a through hole <NUM>. The through hole <NUM> has a non-circular cross section in a plane perpendicular to a central or longitudinal axis of the intermediate part <NUM>. The central or longitudinal axis extends through the centre of the intermediate part <NUM> and is illustrated in the left image of <FIG> by the dashed line.

The through hole <NUM> of the intermediate part <NUM> can have any suitable shape. In examples, the through hole is configured to allow the first and second retainers <NUM>, <NUM> to be located through the intermediate part <NUM>.

In the examples the through hole <NUM> of the intermediate part <NUM> is configured to allow the first and second retainers <NUM>, <NUM> and a lower portion of an inner part <NUM>, <NUM>, such as the non-threaded portion <NUM> of the inner part <NUM>, to be located through the intermediate part <NUM>. See, for example, <FIG>.

In <FIG> the through hole <NUM> is shaped to receive the first and second retainers <NUM>, <NUM> and the non-threaded portion <NUM> of inner part <NUM> of <FIG> such that the first and second retainers <NUM>, <NUM> and the inner part <NUM> are rotatably fixed relative to the through hole <NUM>.

That is, outer surface <NUM> of the non-threaded portion <NUM> and the through hole <NUM> can be shaped to rotatably fix the inner part <NUM>, and the first and second retainers <NUM>, <NUM> located in the slot <NUM> of the inner part <NUM>, relative to the through hole <NUM>.

In the example of <FIG> the through hole <NUM> comprises flattened portions configured to interact and/or abut the outer surface <NUM> of the non-threaded portion <NUM> of the inner part <NUM> to rotatably fix the inner part <NUM>, and the first and second retainers <NUM>, <NUM> located in the slot <NUM> of the inner part <NUM>, relative to the through hole <NUM> when the intermediate part <NUM> is located over and/or around the inner part <NUM>.

In the example of <FIG> the through hole <NUM> is configured to allow the first and second retainers <NUM>, <NUM> and the non-threaded portion <NUM> of the inner part <NUM> to be located through the intermediate part <NUM> such that the intermediate portion abuts the first support <NUM> or elongate member. See, for example, <FIG>.

The intermediate part <NUM> of <FIG> comprises an end <NUM> having a shape configured to prevent twisting of the first support <NUM> when, in use, the intermediate part abuts the first support <NUM>. The end <NUM> configured to abut the first support <NUM> can be considered a lower or bottom end <NUM>. The opposite end of the intermediate part <NUM> can be considered an upper or top end.

In <FIG> the end <NUM> of the intermediate part <NUM> comprises two notches <NUM> configured to receive the band of the first support <NUM> when the intermediate part <NUM> is located in an apparatus. This can best be seen in the lower perspective and side views of <FIG>.

The notches <NUM> can be considered recesses, and/or indentations, and/or cut-outs.

The notches <NUM> can have any suitable shape, size and/or form. In the illustrated example the notches <NUM> are configured to securely receive the band of the first support <NUM>.

The notches <NUM> are located on opposite sides of the intermediate part <NUM> and can be considered to form a channel configured to receive the band of the first support <NUM>.

In the example of <FIG> a curved surface joins each notch <NUM> to an inner surface of the through hole <NUM>. This can best be seen in the lower perspective view of <FIG>. Accordingly, in some examples, the notches <NUM> and curved surfaces can be considered to form a curved band channel.

The end <NUM> of the intermediate part <NUM> can have a concave curved profile configured to match the curvature of the band of the first support <NUM> and/or the support object such as a pipe. This can best be seen in the front view of the intermediate part <NUM> in <FIG>.

The intermediate part <NUM> of <FIG> is similar to the intermediate part <NUM> of <FIG> and can be as described in relation to <FIG>.

However, the through hole <NUM> of the intermediate part <NUM> of <FIG> is different compared to the through hole <NUM> of the intermediate part <NUM> of <FIG>.

Although the through hole <NUM> of the intermediate part <NUM> of <FIG> is configured to perform a similar/same function as the through hole <NUM> of the intermediate part <NUM> of <FIG>, the shape of the through hole <NUM> of the intermediate part <NUM> of <FIG> is different.

The intermediate part <NUM> of <FIG> can be considered to be configured for use with the inner part <NUM> of <FIG> and the intermediate part <NUM> of <FIG> can be considered to be configured for use with the inner part <NUM> of <FIG>.

The through hole <NUM> in the example of <FIG> is shorter in the direction running front to back of the intermediate part <NUM> compared to the through hole <NUM> of the intermediate part <NUM> of <FIG>.

This is because, with regard to the inner part <NUM> of <FIG>, the first and second retainers <NUM>, <NUM> can be located in the slot <NUM> and the intermediate part <NUM> located over the inner part <NUM> without any movement of the inner part <NUM> along the front to back length of the slot <NUM>.

However, to allow the intermediate part <NUM> to be located over the inner part <NUM> of <FIG>, movement of the inner part <NUM> along the front to back length of the slot is used to allow the non-threaded portion <NUM> to be located in the through hole <NUM> and the first and second retainers <NUM>, <NUM> to be located in the slot <NUM> of the inner part <NUM>.

The through hole <NUM> of the intermediate part <NUM> of <FIG> is configured to cooperate with the flattened portions <NUM> of the inner part <NUM> of <FIG> to rotatably fix the inner part <NUM>, and the first and second retainers <NUM>, <NUM> located in the slot <NUM> of the inner part <NUM>, relative to the through hole <NUM> when the intermediate part <NUM> is located over and/or around the inner part <NUM>.

<FIG> shows an example of a brace <NUM>. In the example of <FIG> an upper perspective view of the brace <NUM> is shown.

The brace <NUM> can be used and/or can form part of any suitable apparatus. For example, the brace <NUM> can form part of an apparatus as described herein.

The brace <NUM> can be considered a support, and/or compression plate, and/or anti-twist part.

The brace <NUM> can have any suitable size and/or shape and/or form to cooperate with one or more other elements of an apparatus as described herein to stabilise and/or support and/or prevent twisting in the apparatus in use. For example, the brace <NUM> can be configured to cooperate with the first support <NUM> to stabilise and/or prevent twisting of the first support <NUM> in use.

In the example of <FIG>, the brace comprises a central portion <NUM> a first arm <NUM> and a second arm <NUM>. The first and second arms <NUM>, <NUM> extend away from the central portion in substantially opposite directions.

The central portion <NUM> is substantially flat and the first and second arms <NUM>, <NUM> extend at an angle relative to the plane of the central portion. In the example of <FIG> the first and second arms <NUM>, <NUM> are positioned at substantially the same angle relative to the central portion <NUM> and can be considered to extend at a downward angle.

In profile, the brace can be considered to substantially form an inverted 'flat bottomed V' shape.

The central portion <NUM> can have any suitable shape and/or size. In examples, the central portion is configured to abut, in use, the upper end of an intermediate part <NUM>. See, for example, 14A, 14B, 15A and 15B.

The central portion <NUM> can have a shape and size to substantially match the upper end of the intermediate part <NUM>. The brace <NUM> in the example of <FIG> can be used in conjunction with the intermediate part <NUM> of <FIG> and the central portion <NUM> of the brace substantially matches the upper end of the intermediate part <NUM> of <FIG>.

The central portion comprises a through hole <NUM>. The through hole <NUM> of the brace <NUM> can have any suitable shape. In examples, the through hole is configured to allow the first and second retainers <NUM>, <NUM> to be located through the brace <NUM>.

In the examples the through hole <NUM> of the brace <NUM> is configured to allow the first and second retainers <NUM>, <NUM> and a lower portion of an inner part <NUM>, <NUM>, such as the non-threaded portion <NUM> of the inner part <NUM>, to be located through the brace <NUM>. See, for example, <FIG>.

In examples, the through hole <NUM> can be configured to substantially match a corresponding through hole <NUM> of an intermediate part <NUM>. In the example of <FIG>, the through hole <NUM> is configured to substantially match the through hole <NUM> of the intermediate part <NUM> of <FIG>. Accordingly, the brace <NUM> of <FIG> can be considered to be configured for use with the intermediate part <NUM> of <FIG> and therefore the inner part <NUM>.

The central portion <NUM> can be considered a connection portion, and/or a slotted portion.

The arms <NUM> and <NUM> can have any suitable size and/or form. In <FIG> the arms <NUM>, <NUM> substantially match and are generally rectangular in shape.

The arms <NUM> and <NUM> can be considered extended portions, and/or support parts, and/or legs.

The distal ends of the arms <NUM>, <NUM> comprise a notch <NUM> configured to receive the band of the first support <NUM> when the brace <NUM> is located in an apparatus. See, for example, <FIG> and <FIG>.

The notches <NUM> are located at the centre of the distal end of the arms <NUM>, <NUM> and can be considered to form a channel configured to receive the band of the first support <NUM>.

The brace <NUM> of <FIG> is similar to the brace <NUM> of <FIG> and can be as described in relation to <FIG>.

However, the through hole <NUM> of the brace <NUM> of <FIG> is different compared to the through hole <NUM> of the brace <NUM> of <FIG>.

The through hole <NUM> of the brace <NUM> of <FIG> is configured to substantially match the through hole <NUM> of the intermediate part <NUM> of <FIG>.

The brace <NUM> of <FIG> can be considered to be configured for use with the intermediate part <NUM> of <FIG> and/or the inner part <NUM> of <FIG> and the brace <NUM> of <FIG> can be considered to be configured for use with the intermediate part <NUM> of <FIG> and/or inner part <NUM> of <FIG>.

<FIG> shows an example apparatus <NUM>, along with a threaded rod <NUM>. The apparatus can be considered an apparatus <NUM> for supporting an object. In <FIG>, the apparatus <NUM> is shown in an unassembled condition.

The apparatus <NUM> is shown in an assembled condition in <FIG>.

The apparatus <NUM> includes first and second retainers <NUM>, <NUM>, a first support <NUM> including a first support surface, and a fastener <NUM>. The fastener <NUM> comprises an inner part <NUM> and an outer part <NUM>. In this example, the apparatus <NUM> is for supporting a pipe from the threaded rod <NUM>.

The apparatus <NUM> of <FIG> also comprises an intermediate part <NUM> and a brace <NUM>. In the example of <FIG> the apparatus comprises the inner part <NUM> of <FIG>, the intermediate part <NUM> of <FIG> and the brace <NUM> of <FIG> which are configured for use with the inner part <NUM> of <FIG>.

As can be seen in <FIG>, in the assembled state the intermediate part <NUM> abuts the first support <NUM> with the band of the first support <NUM> located in the notches <NUM> of the intermediate part <NUM>. The brace <NUM> is located on the intermediate part <NUM> and the band of the first support <NUM> is located in the notches <NUM> of the brace. The outer part <NUM> abuts the brace <NUM>.

<FIG> shows a side view and cross section of an assembled apparatus.

The example shown in <FIG> corresponds to the example shown in <FIG>, however in the example of <FIG> the brace <NUM> is not present.

The example shown in <FIG> corresponds to the example shown in <FIG>. The brace <NUM> is present in the example of <FIG>.

There is thus described an apparatus (example first <NUM>, second <NUM> and third apparatuses are described herein) for supporting an object with a number of advantages. The apparatus is simple to assemble relative to conventional apparatuses, especially for workers using the apparatus at height. The apparatus can utilise a single joint to couple a support to for instance a wall, ceiling or beam (via a threaded rod or otherwise), and thus has a reduced likelihood of failure relative to those with multiple joints. The load in the joint is shared equally between both the first and second retainers, which also reduces the possibility of failure. Furthermore, the support and retainers can be manufactured from a single band, providing for simple and low-cost manufacture.

Additionally, alternatively, the apparatus can be secure and resistant to twisting in use.

<FIG> Illustrate a further example apparatus <NUM>. <FIG> shows a perspective view of a fourth example support <NUM> and <FIG> shows a magnified view of <FIG>. The fourth support <NUM> includes a fourth support surface which is similar to the first support surface of the first support <NUM>. A first retainer <NUM> extending from the fourth support <NUM> is for coupling at least in part by the fourth support surface to a second retainer <NUM> extending from the fourth support <NUM>. The first and second retainers <NUM>, <NUM> are similar to the first and second retainers <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>.

The fourth support <NUM> differs from the first support <NUM> in that the stop <NUM> of the first retainer <NUM> and the stop <NUM> of the second retainer <NUM>, extend perpendicular to the screw axis inwardly, towards the screw axis, rather than outwardly. That is, the folded section of each retainer <NUM>, <NUM>, that comprises each stop <NUM>, <NUM>, is folded inwards, towards the screw axis, rather than folded outwards. This leads to the first retainer <NUM> and second retainer <NUM> being spaced apart in a direction perpendicular to the screw axis.

<FIG> shows an example of an inner part of a fastener. The inner part <NUM> shown in this example is similar to the inner parts <NUM>, <NUM>, <NUM> of <FIG>, <FIG>, and <FIG> respectively; and comprises an external thread <NUM>, at least one slot <NUM>, a recess <NUM> and an elongate opening <NUM>. In examples, one or more of the features of the inner part <NUM> of <FIG> can be changed and/or omitted. For example, the recess <NUM> and/or elongate opening <NUM> can be omitted.

The inner part <NUM> of <FIG> differs from the previous example inner parts <NUM>, <NUM><NUM> in that the at least one slot <NUM> comprises a dividing portion <NUM> which divides the at least one slot <NUM> such that it comprises a first portion <NUM> that is shaped to receive the first retainer <NUM> and a second portion <NUM> that is shaped to receive the second retainer <NUM>. The dividing portion <NUM> may provide some of the walls of the slot <NUM>.

The dividing portion <NUM> may have a substantially rectangular cross section. In the example of <FIG> the dividing portion extends across the entirety of the slot <NUM> in a direction perpendicular to the screw axis, but does not extend across the entirety of the slot <NUM> in a direction parallel to the screw axis. In some examples, the dividing portion <NUM> may have a different form, for example, the dividing portion <NUM> may be comprised of multiple separate parts. See, for example, <FIG>.

The first portion <NUM> of the slot <NUM> is shaped to receive the first retainer <NUM> such that the first retainer <NUM> is rotatably fixed relative to the first portion <NUM> and the stop <NUM> prevents the first retainer <NUM> from exiting the first slot in a direction co-incident with or parallel to the screw axis. The second portion <NUM> of the slot <NUM> is shaped to receive the second retainer <NUM> such that the second retainer <NUM> is rotatably fixed relative to the second portion <NUM> and the stop <NUM> prevents the second retainer <NUM> from exiting the second portion <NUM> in a direction co-incident with or parallel to the screw axis.

In the example of <FIG>, the first and second portions <NUM>, <NUM> are each elongate, are each through holes and each have a substantially rectangular cross section. The first portion <NUM> is substantially parallel with the second portion <NUM>. The first and second portions <NUM>, <NUM> at least partially overlap in a direction parallel to the screw axis. They may substantially overlap such that the first and second portions <NUM>, <NUM> are substantially level. In the illustrated example, the first and second portions <NUM>, <NUM> are joined by the recess <NUM>, which is located at the distal end of the inner portion <NUM>. In some examples, the first and second portions <NUM>, <NUM> can have a different form. For example, they can have non-rectangular cross sections and/or the recess <NUM> can be omitted and the first and second portions <NUM>, <NUM> can be entirely separate.

The elongate opening <NUM> of the slot <NUM> provides an opening to each of the first and second portions <NUM>, <NUM>. Each of the first portion <NUM> and the second portion <NUM> may comprise any of the features as described previously concerning the slot <NUM>.

The at least one slot <NUM> of <FIG> may be considered to be two separate slots <NUM>, <NUM>. That is, the first portion <NUM> of at least one slot <NUM> may be considered a first slot <NUM> and the second portion <NUM> of at least one slot <NUM> may be considered a second slot <NUM>. As such, in examples, the at least one slot <NUM> comprises at least two slots <NUM>, <NUM>. Each of the first slot <NUM> and the second slot <NUM> may comprise any of the features as described previously concerning the slot <NUM>, the first portion <NUM> and the second portion <NUM>.

In some examples, the inner part <NUM> of <FIG> may comprise a non-threaded portion <NUM> similar to the inner part <NUM> of <FIG>, and/or flattened portions <NUM> similar to the inner part <NUM> of <FIG>, such that the inner part <NUM> is configured to cooperate with the intermediate part <NUM> of <FIG> or <FIG>.

<FIG> shows a side view and cross section of an example apparatus <NUM>, the apparatus <NUM> being in an assembled condition. The apparatus <NUM> includes first and second retainers <NUM>, <NUM>, a fourth support <NUM> including a fourth support surface, a fastener <NUM> and an intermediate part <NUM>. The fastener <NUM> comprises an inner part <NUM> and an outer part <NUM>. In this example, the apparatus <NUM> is for supporting a pipe from the threaded rod <NUM>.

<FIG> Illustrate another further example apparatus. <FIG> shows a perspective view of a fifth example support and <FIG> shows a magnified view of <FIG>. A first retainer <NUM> extending from the fifth support <NUM> is for coupling at least in part by the fifth support surface to a second retainer <NUM> extending from the fifth support <NUM>. The fifth support <NUM> includes a fifth support surface which is similar to the first support surface of the first support <NUM>.

The first and second retainers <NUM>, <NUM> are similar to the first and second retainers <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>. However, they differ in that for the first and second retainers <NUM>, <NUM>, the stop <NUM>, <NUM> is not formed from a folded section of the first or second retainer <NUM>, <NUM>, and is instead formed by at least one kink <NUM>, <NUM> in at least one of the first and second retainer <NUM>, <NUM>. The stop <NUM> of the first retainer <NUM> may be formed by at least one kink <NUM> in the first retainer <NUM>, and the stop <NUM> of the second retainer <NUM> may be formed by at least one kink <NUM> in the second retainer <NUM>. The at least one kink <NUM>, <NUM> may be a twist, bend, or curve. The at least one kink <NUM>, <NUM> may be a portion of the retainer <NUM>, <NUM> where the retainer <NUM>, <NUM> changes direction. For example, changing direction from extending at least partially inwardly, towards the screw axis, to extending at least partially outwardly, away from the screw axis. In some examples, such as in <FIG>, a retainer <NUM>, <NUM> may comprise both at least one kink <NUM>, <NUM> and a folded section of the retainer <NUM>, <NUM>.

In the example of <FIG> each stop <NUM>, <NUM> is formed by two kinks <NUM>, <NUM> in the respective retainer <NUM>, <NUM>. For each retainer <NUM>, <NUM> one of the kinks <NUM>, <NUM> is provided at or towards a distal end of the retainer <NUM>, <NUM>, and so the stop <NUM>, <NUM> is a distal stop <NUM>, <NUM>.

The first and second retainers <NUM>, <NUM> can have any suitable shape. In the example of <FIG> they are substantially non-linear in shape. They may be at least one of curved, arced, crimped, irregular, kinked, twisted, sawtooth shaped, and wave shaped. As they extend from the fifth support <NUM>, the retainers <NUM>, <NUM> each alternate between extending at least partially inwardly, towards the screw axis, and extending at least partially outwardly, away from the screw axis.

<FIG> shows an example of an inner part of a fastener. The inner part <NUM> shown in this example is similar to the inner parts <NUM>, <NUM>, <NUM>, <NUM> of <FIG>, <FIG>, <FIG> respectively, and <FIG>; and comprises an external thread <NUM>, at least one slot <NUM>, and an elongate opening <NUM>. In examples, one or more of the features of the inner part <NUM> of <FIG> can be changed and/or omitted. For example, the elongate opening <NUM> can be omitted. The inner part <NUM> of <FIG> differs from the previous example inner parts <NUM>, <NUM><NUM>, <NUM> in that the at least one slot <NUM> comprises at least one kink.

The at least one slot <NUM> and at least one of the first and second retainers <NUM>, <NUM> may have cooperative shapes. For example, the at least one slot <NUM> and at least one of the first and second retainers <NUM>, <NUM> may have inverse shapes, such that at least one of the first and second retainers <NUM>, <NUM> can fit inside the slot <NUM>. In some examples, the at least one slot <NUM> and at least one of the first and second retainers <NUM>, <NUM> may have different shapes, for example, a retainer <NUM>, <NUM> may comprise at least one kink <NUM>, <NUM> whilst the at least one slot <NUM> is straight and so does not comprise at least one kink, such as in <FIG>.

The at least one slot <NUM> and at least one of the first and second retainers <NUM> are configured to cooperate to provide the stop <NUM>, <NUM>. At the distal end of the retainers <NUM>, <NUM>, the ends of the retainers <NUM>, <NUM> come together. These ends cooperate with the walls of the slot <NUM> to provide a distal stop <NUM>, <NUM>. The slot <NUM> and at least one of the first and second retainers <NUM>, <NUM> may fit together with an interference fit. This helps to prevents the first and second retainer <NUM>. <NUM> from exiting the slot <NUM> in a direction co-incident with or parallel to the screw axis.

The at least one slot <NUM> may comprise more than one kink. The walls of the at least one slot <NUM> may be substantially non-linear in shape such that the at least one slot <NUM> is substantially non-linear in shape. The walls may be at least one of curved, arced, crimped, irregular, kinked, twisted, sawtooth shaped, and wave shaped. The slot <NUM> can alternate between extending at least partially inwardly, towards the screw axis, and extending at least partially outwardly, away from the screw axis.

In some examples, such as in <FIG>, the inner part <NUM> is similar to the inner part <NUM> of <FIG>, in that it also comprises a dividing portion <NUM>. However, the dividing portion <NUM> of <FIG> comprises two separate parts. The parts are separated from another in a direction parallel to or co-incident with the screw axis. The dividing portion <NUM> divides the at least one slot <NUM> such that it comprises a first portion <NUM> that is shaped to receive the first retainer <NUM> and a second portion <NUM> that is shaped to receive the second retainer <NUM>.

In the example of <FIG>, the first and second portions <NUM>, <NUM> are each elongate, through holes. The first portion <NUM> is substantially parallel with the second portion <NUM> and they are joined by a recess. The first and second portions <NUM>, <NUM> at least partially overlap in a direction parallel to the screw axis. This overlap may be substantial such that the first and second portions <NUM>, <NUM> are substantially level. In the illustrated example, the first and second portions <NUM>, <NUM> are out of phase, specifically antiphase, with each other, whereas in other examples they are in phase with each other. Each of the first portion <NUM> and the second portion <NUM> may comprise any of the features as described previously concerning the slot <NUM>, in particular the shape.

<FIG> shows a side view and cross section of an example apparatus, the apparatus being in an assembled condition. The apparatus <NUM> includes first and second retainers <NUM>, <NUM>, a fifth support <NUM> including a fifth support surface, a fastener <NUM> and an intermediate part <NUM>. The fastener <NUM> comprises an inner part <NUM> and an outer part <NUM>. In this example, the apparatus <NUM> is for supporting a pipe from the threaded rod <NUM>.

<FIG> Illustrate another further example apparatus. <FIG> shows a perspective view of a sixth example support and <FIG> shows a magnified view of <FIG>. The sixth support <NUM> includes a sixth support surface which is similar to the first support surface of the first support <NUM>. A first retainer <NUM> extending from the sixth support <NUM> is for coupling at least in part by the sixth support surface to a second retainer <NUM> extending from the sixth support <NUM>.

The first and second retainers <NUM>, <NUM> of the sixth example support <NUM> are similar to the first and second retainers <NUM>, <NUM> of the fifth example support <NUM>. However, they differ in that for the first and second retainers <NUM>, <NUM>, the stop <NUM>, <NUM> is formed from a folded section of the first or second retainer <NUM>, <NUM>, which is folded outwards, away from the screw axis, rather than folded outwards. Additionally, the folded section for each retainer <NUM>, <NUM> is curved/curled.

<FIG> shows an example of an inner part <NUM> of a fastener. The inner part <NUM> shown in this example is similar to the inner part <NUM> of <FIG>; and comprises an external thread <NUM>, at least one slot <NUM>, a recess <NUM>, a dividing portion <NUM> and an elongate opening <NUM>. The inner part <NUM> of <FIG> differs from the inner part <NUM> of <FIG> in that the at least one slot <NUM> does not comprise a recess and the dividing portion <NUM> extends across the entirety of the slot in a direction parallel to the screw axis. Similarly to the at least one slot <NUM> of <FIG>, the at least one slot <NUM> of <FIG> may be considered to comprise two separate slots <NUM>, <NUM> or to comprise two separate slot portions <NUM>, <NUM>.

<FIG> Illustrate another further example apparatus. <FIG> shows a perspective view of a seventh example support. The seventh support includes a seventh support surface (not visible) which is similar to the first support surface of the first support <NUM>. A first retainer <NUM> extending from the seventh support is for coupling at least in part by the seventh support surface to a second retainer <NUM> extending from the seventh support.

The first and second retainers <NUM>, <NUM> of the seventh example support are similar to the first and second retainers <NUM>, <NUM> of the sixth example support <NUM>. However, they differ in that the first retainer <NUM> is straight and so does not comprise at least one kink, whilst the second retainer is non-linear and so comprises at least one kink <NUM>.

<FIG> shows a cross section of an example apparatus <NUM>, the apparatus <NUM> being in an assembled condition. The apparatus <NUM> includes first and second retainers <NUM>, <NUM>, and an inner part <NUM> of a fastener. The inner part <NUM> shown in this example is the inner part <NUM> of <FIG>.

In this example, the second retainer <NUM> comprises at least one kink <NUM> whilst the second portion <NUM> of at least one slot <NUM>, which receives the second retainer <NUM>, is straight and so does not comprise at least one kink. The second retainer <NUM> is configured to deform elastically to fit inside the second portion <NUM> of the at least one slot <NUM>, such that the second retainer <NUM> is straight when located inside the at least one slot <NUM>. That is, the at least one kink <NUM>, is configured to be deformed by the at least one slot <NUM> such that it is straightened. This provides an interference fit between the second retainer <NUM> and the at least one slot <NUM>, which improves the connection between the second retainer <NUM> and the inner part <NUM> of the fastener.
