DETAILED DESCRIPTION

The figures illustrate a mounting arrangement 10, an apparatus 100 and a method.

As illustrated in Fig. 1, examples of the disclosure provide a mounting arrangement 10 for securing an item 12 to a body 14 to resist movement of the item 12 relative to the body 14 against a force being applied to the item 12.

The mounting arrangement 10 comprises an item engagement part 16 and a cavity 18 for at least partially receiving the item engagement part 16. The item engagement part 16 comprises a mating surface 20 configured to mate against a surface 22 of the item 12 to be secured when the item engagement part 16 is located within the cavity 18.

The cavity 18 is shaped such that the amount of friction between the mating surface 20 and the surface 22 of the item 12 to be secured is defined by the extent to which the item engagement part 16 is located within the cavity 18.

In Fig. 1A, the item engagement part 16 has not yet been located within the cavity 18. In Fig. 1B, the item engagement part 16 has been located within the cavity 18. Accordingly, the mating surface 20 has mated against the surface 22 of the item 12 to be secured. The extent to which the item engagement part 16 is located within the cavity 18 defines the amount of friction between the mating surface 20 and the surface 22 of the item 12 to be secured. Fig. 1B could illustrate a condition of the mounting arrangement 10 wherein the item engagement part 16 is located within the cavity 18 to the maximum extent permitted by the mounting arrangement 10. In this condition, the amount of friction between the mating surface 20 and the surface 22 of the item 12 to be secured is the maximum amount obtainable.

Alternatively, Fig. 1B could illustrate a condition of the mounting arrangement 10 where the item engagement part 16 is not located within the cavity 18 to the maximum extent permitted by the mounting arrangement 10. Accordingly, in this condition the amount of friction could be increased by moving the item engagement part 16 further into the cavity 18.

Fig. 10 illustrates the same condition of the apparatus as illustrated in Fig. 1B. However, in Fig. 10 arrows are provided to illustrate that an in use vertical upwards movement of the item engagement part 16 into the cavity 18 (vertical arrow) translates into an in use horizontal movement of the mating surface 20 toward the surface 22 of the item 12 to be secured (horizontal arrow). Accordingly, the in use vertical upwards movement of the item engagement part 16 into the cavity 18 provides a clamping force in a horizontal direction against the surface 22 of the item 12 to be secured.

In examples of the disclosure, the volume defined by the cavity 18 is less than the volume defined by the item engagement part 16, that is, the item engagement part 16 is too big to be completely received in the cavity 18. However, the item engagement part 16 and the cavity 18 are shaped such that the item engagement part 16 can be partially received in the cavity 18. Accordingly, as the item engagement part 16 is moved vertically into the cavity 18 a pinch point is reached at which further vertical movement is resisted by the internal dimensions of the cavity 18. Further vertical movement of the item engagement part 16 beyond the pinch point increases the amount of friction between the mating surface 20 and the surface 22 of the item 12 to be secured, as described above.

Fig. 1 also illustrates an apparatus 100 comprising a body 14 and an item 12 securable to the body 14 by the mounting arrangement 10 to resist movement of the item 12 relative to the body 14 against a force being applied to the item 12.

Figs. 2 to 8 illustrate another mounting arrangement 10, and an apparatus 100 comprising the mounting arrangement 100.

In Figs. 2 to 8, the body 14 of the apparatus 100 comprises a raised platform 24 and the item 12 to be secured comprises a support handle 26. In the illustrated example, a pair of support handles 26 is provided, and each respective support handle 26 comprises a pair of legs 28. In the illustrated example, the apparatus 100 comprises a separate mounting arrangement 10 for each respective leg 28 of each pair of support handles 26, that is, four separate mounting arrangements 10.

In use, the apparatus 100 may be located adjacent to a raised area such that the raised platform 24 is at an intermediate height relative to the raised area. Accordingly, the raised platform 24 defines a step up to the raised area to facilitate access to the raised area. The pair of support handles 26 may be used by a person to steady themselves and to transfer some of the force from their legs to their arms.

Accordingly, in use a person may apply a downward and outward force to the support handles 26 As described above in relation to Fig. 1, the cavity 18 of the mounting arrangement 10 is shaped such that the amount of friction between the mating surface 20 and the surface 22 of the item 12 to be secured is defined by the extent to which the item engagement part 16 is located within the cavity 18. Movement of an item 12 which would otherwise be caused by a force being applied to the item 12 is resisted by the friction between the mating surface 20 and the corresponding surface 22 of the item 12 to be secured.

In the example illustrated in Figs 2 to 8, the friction between the mating surface 20 of each respective item engagement part 16 and the corresponding surface 22 of each respective leg 28 resists outward movement of the respective support handles 26 away from each other.

In addition to the features already described, for which the same reference numerals have been used, Figs. 2 to 8 illustrate the following further features.

As best illustrated in Figs. 6C and 7C, in some examples the mounting arrangement 10 comprises tightening means 34 operable to control the extent to which the item engagement part 16 is located within the cavity 18. In the illustrated example, the tightening means 34 comprises a tightening screw 36 receivable in a threaded opening 38 in the item engagement part 16. Rotation of the tightening screw 36 in the threaded opening 38 controls the extent to which the item engagement part 16 is located within the cavity 18.

In some examples, in use the item engagement part 16 is initially pushed into the cavity 18 to a certain point, which may be the point at which there is resistance to the item engagement part 16 being pushed further into the cavity 18. The tightening screw 36 is then located in the threaded opening 38 and rotated to control the extent to which the item engagement part 16 is located within the cavity 18. Tightening the screw 36 causes the item engagement part 16 to move further into the cavity 18. The further the item engagement part 16 moves into the cavity 18, the greater the amount of friction between the mating surface 20 and the surface 22 of the item 12 to be secured.

The tightening screw 36 is located through an opening 54 in an in use top face of the base 14 of the apparatus 10. Accordingly, the tightening screw 36 is readily accessible.

As best illustrated in Figs. 60, 70, and 8, in the illustrated example the cavity 18 comprises an inclined internal surface 40 which is configured to engage with an inclined surface 42 of the item engagement part 16. The cavity 18 has an internal taper. The item engagement part is tapered. In the illustrated example, the item engagement part 16 is substantially wedge shaped.

The amount of friction between the mating surface 20 and the surface 22 of the item 12 to be secured is defined by the extent to which the respective inclined surfaces 40, 42 overlap. Fig. 60 illustrates in cross-sectional view the overlap of the inclined surfaces 40, 42 in a condition wherein the item engagement part 16 is located within the cavity 18.

The further the item engagement part 16 moves into the cavity 18, the greater the extent to which the respective inclined surfaces 40, 42 overlap, and therefore the greater the amount of friction between the mating surface 20 and the surface 22 of the item 12 to be secured.

Accordingly, and as illustrated in Fig. 10, an in use vertical upwards movement of the item engagement part 16 into the cavity 18 translates into an in use horizontal movement of the mating surface 20 toward the surface 22 of the item 12 to be secured. Accordingly, the in use vertical upwards movement of the item engagement part 16 into the cavity 18 provides a clamping force in a horizontal direction against the leg 28 of the support handle 26.

As best illustrated in Fig. 8E, the inclined internal surface 40 of the cavity 18 is defined by a plurality of formations 44 which extend to a progressively greater extent into the cavity 18 from the mouth of the cavity 18. In the illustrated example, the plurality of formations 44 is a plurality of ribs 46 which are angled into the cavity 18 from the mouth of the cavity 18.

As noted above, Fig 8 illustrates a condition of the apparatus 10 and mounting arrangement 100 without the item engagement part 16 of the mounting arrangement 10 present.

Fig. 8E illustrates a part 31 of a step molding which in use defines a surface that restricts the item to be secured 12 (for example, the leg 28 of Figs. 2 to 7) from falling completely through the body 14 (for example, the raised platform of Figs. 2 to 7). An opening 33 is provided through this surface through which the fastening bolt 32 can be inserted to interact with the reinforcement member 30 when the item to be secured 12 (for example, the leg 28 of Figs. 2 to 7) is in place.

As best illustrated in Fig. 9, in the illustrated example the mating surface 20 of the item engagement part 16 is textured, and has an inwardly curved (concave) profile 48. The inwardly curved profile 48 corresponds to an outwardly curved (convex) profile 50 of the surface 22 of the item 12 to be secured. In the illustrated example, the item 12 to be secured is a leg 28 which is substantially tubular and therefore has an outwardly curved profile. The mating surface 20 comprises a plurality of ridges 52. The ridges 52 extend horizontally. The textured mating surface 20 provides greater resistance to vertical pull of the item 12 to be secured.

In the examples illustrated in Figs. 2 to 8, each of the items 12 to be secured, that is, each of the four legs 28 comprises a reinforcement member 30 located within the end portion thereof. The reinforcement member 30 prevents the end portion of the leg 28 from being compressed out of its original shape, that is from being crushed, when the item engagement part 16 is located in the cavity 18. The reinforcement member 30 may be understood as a top hat bushing.

In the examples illustrated in Figs. 2 to 8, each of the four legs 28 is fastened to the raised platform 24 by a fastening bolt 32. This type of fastening alone does not in use sufficiently resist movement of the handles 28 caused by a force being applied to the handles 28 by a person. The fastening bolt 32 screws into the reinforcing member 30. The head 56 of the fastening bolt 32 can be seen in Fig. 2B.

The figures also illustrate a method of securing an item 12 to a body 14 using a mounting arrangement 10 as previously described to resist movement of the item 12 relative to the body 14 against a force being applied to the item 12. The method comprises locating the item engagement part 16 in the cavity 18 such that a mating surface 20 of the item engagement part 16 mates against a surface 22 of the item 12 to be secured.

The method may also comprise adjusting the extent to which the item engagement part 16 is located within the cavity 18 to define the amount of friction between the mating surface 20 and the surface 22 of the item 12 to be secured.

There is thus described a mounting arrangement 10, an apparatus 100 and a method with a number of advantages as detailed above.

Although embodiments of the present invention 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 invention as claimed. For example, the mounting arrangement 10 and apparatus 100 could comprise any suitable material, for instance, rigid plastics.

Features described in the preceding description may be used in combinations other than the combinations explicitly described.

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 embodiments, those features may also be present in other embodiments whether described or not.
