Embodiments of the present disclosure relate to an apparatus for supporting an object. Some relate to an apparatus for supporting a pipe from a threaded rod.
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.
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 distal stop; a fastener, comprising: an outer part including an internal surface that comprises a threaded portion; an inner part including an external thread arranged to enable the outer part to threadably rotate around the inner part, and a slot having a non-circular cross section in a plane perpendicular to the screw axis of the external thread, the slot being shaped to receive the first and second retainers together, such that the first and second retainers are rotatably fixed relative to the slot and the distal stop prevents the retainers from exiting the slot in a direction co-incident with or parallel to the screw axis.

According to various, but not necessarily all, embodiments there is provided examples as claimed in the appended claims.
Some examples will now be described with reference to the accompanying drawings in which:
The first support 130 can be considered an elongate member.
As shown best in
The first retainer 110 comprises a stop 112. The stop 112 may be a distal stop 112. The distal stop 112 is provided at a distal end of the first retainer 110, and the distal stop 112 is wider than the adjacent portion of the first retainer 110. In other words, the distal stop 112 extends to a greater extent than the adjacent portion of the first retainer 110 in a dimension perpendicular to the length dimension of the first retainer 110. In this example, the distal stop 112 is formed from a folded section of the retainer 110. The distal end of the retainer 110 may be folded 180° to form the distal stop 112, such that the distal stop 112 is double the thickness of the adjacent portion of the retainer 110. This is also illustrated in
The first retainer 110 is coupled at least in part by the first support surface to the second retainer 120. The first support 130 comprises the first support surface for supporting an object. The first support 130 of
In this example of
As shown in
The inner part 150 further includes a slot 154 with a non-circular cross section in a plane perpendicular to the screw axis of the external thread 152. The slot is defined by walls. The slot 154 is shaped to receive the first and second retainers 110, 120 together, such that the first and second retainers 110, 120 are rotatably fixed relative to the slot 154, when located therein. This is illustrated in
In the example of
The corresponding cross section of the slot 154 and the first and second retainers 110, 120 combined means that torque can be transferred between the first and second retainers 110, 120 and the slot 154, with the first and second retainers 110, 120 acting as a “internal spanner”, which can cause or prevent rotation of the inner part 150.
The distal stops 112, 122 of the first and second retainers 110, 120 prevent the retainers 110, 120 from exiting the slot 154 in a direction co-incident with or parallel to the screw axis of the inner part 150. The distal stops 112, 122 of the first and second retainers 110, 120 combined are wider than the slot 154, such that the stops 112, 122 are unable to pass through the slot 154 when the retainers 110, 120 are located in the slot 154. In other words, the distal stops 112, 122 of the first and second retainers 110, 120 combined extend to a greater extent than the slot 154 in a dimension perpendicular to the screw axis to prevent the retainers 110, 120 from exiting the slot 154 in a direction co-incident with or parallel to the screw axis.
The slot 154 of the inner part 150 includes an elongate opening 158 extending parallel to the screw axis, which is configured to receive the first and second retainers 110, 120 from a direction perpendicular to the screw axis of the external thread 152. The elongate opening 158 is present in the surface comprising the external thread 152. In this example, the elongate opening 158 of the inner part 150 is shaped to receive only one of the first and second retainers 110, 120 at a time. Therefore, when the first and second retainers 110, 120 are both in the slot 154, the retainers 110, 120 are more secure in the slot 154, as the opening 158 is narrower than the combined width of the first and second retainers 110, 120. However, in other examples, the elongate opening 158 of the inner part 150 may be wider, and shaped to receive both the first and second retainers 110, 120 simultaneously.
As illustrated in
The outer part 160 is configured to threadably rotate around the inner part 150 and the threaded rod 500. Rotation of the outer part 160 on the inner part 150 and threaded rod 500 simultaneously causes the inner part 150 to be urged towards or away from the end of the longitudinal end of the threaded rod 500.
The outer part 160 includes one or more planar surfaces 166 on its external surface to enable a spanner to be received thereon and rotate the outer part 160. In the example shown in

The alternate first and second retainers 310, 320 are similar to the first and second retainers 110, 120, 210, 220. However, in this example the alternate second retainer 320 is longer than the alternate first retainer 310, i.e. the elongate alternate second retainer 320 has a greater length dimension than the elongate alternate first retainer 310. The alternate second retainer 320 may be at least twice the length of the alternate first retainer 310. As illustrated in
The outer part of the second fastener is not shown in
The distal stop 312 of the alternate first retainer 310 prevents the alternate first and second retainers 310, 320 from exiting the slot 354 of the inner part 350 of the second fastener in a direction co-incident with or parallel to the screw axis of the inner part 350. The alternate second retainer 320 and the distal stop 312 of the alternate first retainer 310 combined are wider than the slot 354, such that the stop 312 is unable to pass through the slot 354 when the retainers 310, 320 are located in the slot 354. In other words, the alternate second retainer 320 and the distal stop 312 of the alternate first retainer 310 combined extend to a greater extent than the slot 354 in a dimension perpendicular to the screw axis to prevent the retainers 310, 320 from exiting the slot 354 in a direction co-incident with or parallel to the screw axis.
The alternate second retainer 320 includes attachment means for use in attaching the alternate second retainer 320 to a fixing. In this example, the attachment means is a distal stop 322. In other examples, the attachment means of the alternate second retainer 320 could for instance be a distal hook.
Furthermore, in this particular example, the third apparatus includes a third fastener, and the inner part 450 of the third fastener is shown in
The outer part of the third fastener is not shown in
The distal stop 322 of the alternate second retainer 320 prevents the alternate second retainer 320 from exiting the slot 454 of the inner part 450 of the third fastener in a direction co-incident with or parallel to the screw axis of the inner part 450. The distal stop 322 of the alternate second retainer 320 is wider than the slot 454 of the inner part 450 of the third fastener, such that the stop 322 is unable to pass through the slot 454 when the alternate second retainer 320 is located in the slot 454. In other words, the distal stop 322 of the alternate second retainer 320 extends to a greater extent than the slot 454 of the inner part 450 of the third fastener in a dimension perpendicular to the screw axis to prevent the alternate second retainer 320 from exiting the slot 454 in a direction co-incident with or parallel to the screw axis.
In use, the third support 330 of the third apparatus is first located on an object, such as a pipe. The alternate first and second retainers 310, 320 are then inserted into the slot 354 of the inner part 350 of the second fastener, as shown in

The apparatus 100 includes first and second retainers 110, 120, a first support 130 including a first support surface, and a fastener 140. The fastener 140 comprises an inner part 550 and an outer part 160. In this example, the apparatus 100 is for supporting a pipe from the threaded rod 500.

As can be seen in
The example shown in
The example shown in
There is thus described an apparatus (example first 100, second 200 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.
The fourth support 430 differs from the first support 130 in that the stop 412 of the first retainer 410 and the stop 422 of the second retainer 420, extend perpendicular to the screw axis inwardly, towards the screw axis, rather than outwardly. That is, the folded section of each retainer 410, 420, that comprises each stop 412, 422, is folded inwards, towards the screw axis, rather than folded outwards. This leads to the first retainer 410 and second retainer 420 being spaced apart in a direction perpendicular to the screw axis.
The inner part 750 of
The dividing portion 758 may have a substantially rectangular cross section. In the example of
The first portion 757 of the slot 754 is shaped to receive the first retainer 410 such that the first retainer 410 is rotatably fixed relative to the first portion 757 and the stop 412 prevents the first retainer 410 from exiting the first slot in a direction co-incident with or parallel to the screw axis. The second portion 759 of the slot 754 is shaped to receive the second retainer 420 such that the second retainer 420 is rotatably fixed relative to the second portion 759 and the stop 422 prevents the second retainer 420 from exiting the second portion 759 in a direction co-incident with or parallel to the screw axis.
In the example of
The elongate opening 758 of the slot 754 provides an opening to each of the first and second portions 757, 759. Each of the first portion 757 and the second portion 759 may comprise any of the features as described previously concerning the slot 754.
The at least one slot 754 of
In some examples, the inner part 750 of
The first and second retainers 710, 720 are similar to the first and second retainers 110, 120, 210, 220, 310, 320, 410, 420. However, they differ in that for the first and second retainers 710, 720, the stop 712, 722 is not formed from a folded section of the first or second retainer 710, 720, and is instead formed by at least one kink 713, 723 in at least one of the first and second retainer 710, 720. The stop 712 of the first retainer 710 may be formed by at least one kink 713 in the first retainer 710, and the stop 722 of the second retainer 720 may be formed by at least one kink 723 in the second retainer 720. The at least one kink 713, 723 may be a twist, bend, or curve. The at least one kink 713, 723 may be a portion of the retainer 710, 720 where the retainer 710, 720 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
In the example of
The first and second retainers 710, 720 can have any suitable shape. In the example of
The at least one slot 854 and at least one of the first and second retainers 710, 720 may have cooperative shapes. For example, the at least one slot 854 and at least one of the first and second retainers 710, 720 may have inverse shapes, such that at least one of the first and second retainers 710, 720 can fit inside the slot 854. In some examples, the at least one slot 854 and at least one of the first and second retainers 710, 720 may have different shapes, for example, a retainer 710, 720 may comprise at least one kink 713, 723 whilst the at least one slot 852 is straight and so does not comprise at least one kink, such as in
The at least one slot 854 and at least one of the first and second retainers 710 are configured to cooperate to provide the stop 712, 722. At the distal end of the retainers 710, 720, the ends of the retainers 710, 720 come together. These ends cooperate with the walls of the slot 854 to provide a distal stop 712, 722. The slot 854 and at least one of the first and second retainers 710, 720 may fit together with an interference fit. This helps to prevents the first and second retainer 710. 720 from exiting the slot 854 in a direction co-incident with or parallel to the screw axis.
The at least one slot 854 may comprise more than one kink. The walls of the at least one slot 854 may be substantially non-linear in shape such that the at least one slot 854 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 854 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

The first and second retainers 910, 920 of the sixth example support 930 are similar to the first and second retainers 710, 720 of the fifth example support 730. However, they differ in that for the first and second retainers 910, 920, the stop 912, 922 is formed from a folded section of the first or second retainer 910, 920, which is folded outwards, away from the screw axis, rather than folded outwards. Additionally, the folded section for each retainer 910, 920 is curved/curled.
The first and second retainers 1010, 1020 of the seventh example support are similar to the first and second retainers 910, 920 of the sixth example support 930. However, they differ in that the first retainer 1010 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 1013.
In this example, the second retainer 1020 comprises at least one kink 1013 whilst the second portion 959 of at least one slot 954, which receives the second retainer 1020, is straight and so does not comprise at least one kink. The second retainer 1020 is configured to deform elastically to fit inside the second portion 959 of the at least one slot 954, such that the second retainer 1020 is straight when located inside the at least one slot 954. That is, the at least one kink 1013, is configured to be deformed by the at least one slot 954 such that it is straightened. This provides an interference fit between the second retainer 1020 and the at least one slot 954, which improves the connection between the second retainer 1020 and the inner part 950 of the fastener.
Various modifications can be made without departing from the scope of the invention. For instance, different materials may be used or differently shaped parts may be used to accommodate differently shaped objects. One or more of the retainers may be fastened into the inner part, for instance by welding or gluing. Only one of the first and second retainers may comprise a distal stop. The first and second retainers may be coupled together with a projection on one retainer extending into a corresponding recess on the other retainer. The apparatus may comprise one or more of the threaded rods. As indicated, the inner part of the fasteners may not include a recess for locating the distal stop of a retainer. The distal stop may be located at a different point along the length of the respective retainer.
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, 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 of 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. The use of “first”, “second” or “third” to describe a feature (e.g. a first fastener) does not necessarily imply that a further example of that feature (e.g. a second fastener) is required in that example.
Although examples have been described in the preceding paragraphs with reference to various examples, it should be appreciated that modifications to the examples given can be made without departing from the scope of the claims.
Features described in the preceding description may be used in combinations other than the combinations explicitly described above.
Although functions have been described with reference to certain features, those functions may be performable by other features whether described or not.
Although features have been described with reference to certain examples, those features may also be present in other examples whether described or not.
The term ‘a’ or ‘the’ is used in this document with an inclusive not an exclusive meaning. That is any reference to X comprising a/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’ 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 also 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.
Whilst endeavoring in the foregoing specification to draw attention to those features believed to be of importance it should be understood that 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.
