Description

MOUNTING ASSEMBLY

FIELD OF THE INVENTION

The present invention relates generally to a mounting assembly and to components thereof.

The mounting assembly and components thereof of the present invention are an advance on the teaching of International Patent Application No. PCT/AU96/00443 (International Publication No. WO 97/04159); the contents of which are incorporated herein by reference.

BACKGROUND ART

International Patent Application No. PCT/AU96/00443 discloses a mounting assembly for a member which enables the member to be angularly moved from a storage position to a working position. The mounting assembly has two links (first and second) which are each pivotally mounted to both a support and to a member. A first end of the first link is pivotally mounted to the support and a first end of the second link is pivotally mounted to the support. A second end of the first link is pivotally mounted to the member distal to an end of the member and a second end of the second link is pivotally mounted to the member proximate the end of the member, ie. the second end of the second link is pivotally mounted to the member closer to the end of the member than the second end of the first link. Stop means restrict movement of the member past the working position.

An embodiment of International Patent Application No. PCT/AU96/00443 discloses that a pair of the above mentioned mounting assemblies may be spaced apart to support an ironing board. The first ends of the links of the two mounting assemblies are pivotally mounted to a support which is secured to a wall. The second ends of the links of the pair of mounting assemblies are pivotally mounted to respective spaced apart members which support the ironing board. The pair of mounting assemblies and the pair of members to which they are mounted are spaced apart from one another by about half the longitudinal extent of the working surface of an ironing board with about half the working surface of the ironing board being foldable on to the other half of the working surface. In its storage position, the working surface of the ironing board is folded atop itself and positioned substantially vertically adjacent the support secured to the wall. When the ironing board is desired in its working position, the pair of spaced apart members which support the ironing board are supported during angular movement from their substantially vertical storage position to their substantially horizontal working position by the pair of mounting assemblies . The stop means of each mounting assembly prevents its member moving beyond the working position and supports its member (and hence the ironing board) in the working position. On reaching the working position, the working surface of the ironing board is unfolded and the ironing board is available for use. The foldaway ironing board embodiment of International

Patent Application No. PCT/AU96/ 00443 referred to above is advantageous in that it provides for compact storage in the storage position and in the working position facilitates use equivalent to a conventional portable ironing board of the kind which is supported from the ground by scissor action legs . It is also advantageous compared with other foldaway ironing boards such as those discussed from page 1 line 19 to page 2 line 18 of International Patent Application No. PCT/AU96/00443 because the mounting assembly of International Patent

Application No. PCT/AU96/00443 both facilitates movement between the storage and working positions and supports the ironing board in the working position without any additional supporting struts or legs. However, the foldaway ironing board of International Patent Application No. PCT/AU96/00443 suffers from a significant disadvantage. To enable the pair of mounting assemblies to sufficiently support the ironing board in the working position, they are typically spaced as far apart from one another as possible. In the embodiment referred to above in which the working surface folds atop itself, the mounting assemblies are spaced apart from one another by about half the longitudinal extent of the ironing board. Such spacing apart of the mounting assemblies achieves satisfactory support for the ironing board in the working position but results in two problems . Firstly, the support (s) to which the first ends of the links of the mounting assemblies are pivotally mounted must be secured to a wall or the like. Each mounting assembly could be pivotally mounted to a separate support but for enhanced structural rigidity, they are desirably mounted to a common support. In either case, problems arise in securing the support (s) to a cavity wall. Cavity walls having a series of vertically extending studs clad with sheets of cladding material are frequently employed in residential and travel accommodation. Securing the separate supports to a cavity wall necessitates securing one support to one wall stud and the other support to another wall stud where each mounting assembly is pivotally mounted to a separate support. Where a common support for both mounting assemblies is utilised, the common support could be secured to a single wall stud at about its mid point but such an approach is clearly undesirable due to the potential for failure of the anchorage of the common support to the stud and hence a common support is typically secured to at least two different studs. Secondly, problems can be encountered in movement between the storage position and the working position if the pair of mounting assemblies do not operate in synchronism.

It would be advantageous to provide an arrangement which avoided, or at least ameliorated, the problems described above .

The present invention will be described in the context of a foldaway ironing board but it is to be clearly understood that the present invention is not restricted to a foldaway ironing board because the present invention is readily applicable to a variety of other circumstances. For example, the mounting assembly of the present invention may be used to mount a table in an environment where maximising the use of space is desirable, such as on a boat .

SUMMARY OF THE INVENTION

According to a first aspect of the present invention there is provided a mounting assembly for angularly moving an apparatus between a first position and a second position and for supporting the apparatus in the second position, the mounting assembly including: a support member securable to a single stud of a cavity, wall and arranged, in use, to support the mounting assembly and apparatus when so secured; a first link member having a pair of link arms and a body portion therebetween, first ends of the link arms being pivotally mounted to the support member and second ends of the link arms being pivotally mounted to the apparatus distal to an end of the apparatus; and a second link member having a pair of link arms and a body portion therebetween, first ends of the link arms being pivotally mounted to the support member and second ends of the link arms being pivotally mounted to the apparatus proximal to said end of the apparatus; wherein, in use, interaction between the first and second link members restricts angular movement of the apparatus beyond the second position and supports the apparatus in the second position.

The support member is securable to a single stud of a cavity wall but need not be so secured. That is to say that the support member can be secured, in use, to any suitable support element, such as a masonry wall, but must be capable of being secured to a single stud and support the mounting assembly and the apparatus when secured to a single stud. The support member may be secured directly to the support element by any suitable means including fasteners such as screws. Preferably, however, the support member is indirectly secured to the support element through a mounting plate which is arranged to be directly secured to the support element. Preferably, the support member is releasably securable to the mounting plate . Preferably the support member and mounting plate are securable by interaction of a plurality of slots on one of the support member and the the mounting plate with a plurality of lugs on the other of the support member and the mounting plate. More preferably, the support member is formed with a plurality of slots arranged to receive a corresponding plurality of lugs which project upwardly and outwardly from a face of the mounting plate at an acute angle. In use, the slots are aligned with the lugs as the support member approaches the mounting plate (secured to a support element) and pass over the lugs so that the support member is held against the face of the mounting plate by the lugs. The support member can be unsecured from the mounting plate by reversing this procedure. The mounting plate can preferably be formed from a sheet of metal by sheet metal working operations including cutting, stamping, punching and folding.

Preferably, at least one of the first and second link members is made from a plastic material.

The mounting assembly 10 is securable to a single stud of a cavity wall via mounting plate 12 which is formed with five apertures 14 for screwing the mounting plate 12 to the stud (not shown) . The mounting plate 12 is formed with two lugs 16 which project upwardly and outwardly from a face of the mounting plate 12 at an acute angle to the face. A support member 18 is releasably securable to the mounting plate 12 via two slots 20 which pass over the lugs 16 wedging parts of a body portion 22 of the support member 18 between the lugs 16 and a face 15 of the mounting plate 12. The mounting plate 12 is formed from a sheet of 3 mm mild steel . A pair of vertically extending limbs 24 project normally from the sides of body portion 22 and are separated by a distance of about 120 mm. The limbs 24 have lower portions which project below the body portion 22. Upper portions of the limbs 24 project away from the top of the body portion 22 and are spanned by a head portion 26 which projects normally from the top of the body portion 22 has ends 27, respectively welded to each of the limbs 24. The limbs 24 are formed with aligned upper and lower pairs of apertures 25 arranged to receive upper and lower pivot pins 28 and 30 respectively. The support member 18 is formed from a sheet of 2 mm mild steel, and is powder coated.

A first link member 32 has a pair of link arms 34 and a body portion 36 therebetween. A first end 38 of the first link member 32 has a continuous bore passing therethrough' which is arranged to receive the upper pivot pin 28 and thereby to pivotally mount the first link member 32 to the support member 18.

A second link member 40 has a pair of link arms 42 and a body portion 44 therebetween. A first end 46 of the second link member 40 is formed with a continuous bore through the link arms 42 and body portion 44 which is arranged to pivotally mount second link member 40 to support member 18 via lower pivot pin 30. The first end 46 takes the form of an enlarged boss 47 as compared with the second end 48 of the second link member 40. The boss 47 is .enlarged for the purpose of bearing against the insides of limbs 24 when pivotally mounted thereto by lower pivot pin 30. Lower pivot pin 30 is arranged to be tightened and loosened and thereby vary the pressure exerted on the boss 47 by the limbs 24 to enable interaction between the boss 47 and the limbs 24 to function as a breaking type system in movement between a working position as illustrated in Figure 2 and a storage position as illustrated in Figure 4.

The second end 48 of the second link member 40 is also formed with a continuous bore through link arms 42 and body portion 44 and is arranged to be pivotally mounted to an intermediate member 50 via end pivot pin 52 which is, in use, located proximal the end of the intermediate member 50. The second end 54 of first link member 32 is also formed with a continuous bore 55 through link arms 34 and body portion 38 with first link member 32 being pivotally mounted to intermediate member 50 via pivot pin 56 which passes through the continuous bore 55. Pivot pins 52 and 56 pass through aligned apertures in walls 58 of a pivoting end of intermediate member 50. A box- section frame 60 for a foldaway ironing board (not shown) is welded to intermediate member 50 as subsequently described in relation to Figures 6 and 7. Intermediate member 50 is formed from a sheet of 2 mm mild steel and given a powder coated finish. Box-section 60 is formed from mild steel having a wall thickness of 0.8 mm or 1.0 mm and is given a powder coated finish. First link member 32 and second link member 40 are injection moulded from glass filled nylon. A support plate 62 for the foldaway ironing board (not shown) is mounted on the box-section frame 60. Figure 5 is a side view of the mounting assembly 10, frame 60 and support plate 62 of Figures 2 to 4 in progressive movement between the storage position illustrated at the far left of Figure 5 and the working position illustrated at the far right of Figure 5. The first link member 32 and second link member 40 are shown in order to illustrate operation of the mounting assembly, and for clarity the intermediate member (50 in Figure 1) is only partially shown, although it will be appreciated that in use the first and second link members 32, 40 are pivotally attached to the intermediate member at their respective second ends 48, 54. The four depictions in Figure 5 show operation of the mounting assembly 10 as the frame 60 moves from a storage position in which it is substantially parallel to a vertical wall 80 (which acts as a support element) to a working position, shown at the far right of Figure 5, in which it is substantially normal to the wall . The lower broken line in Figure 5 illustrates the vertical position of the of pivot pin 52 in movement between the storage position and the working position and thus also the vertical position of the bore near the second end 48 of the second link member 40 and of the aperture in the intermediate member 50 through which the pivot pin 52 passes . The upper broken line illustrates the vertical position of the distal side 82 of the frame 60, which furthest from the intermediate member 50 and pivot pins 52, 56. While the drawings are spread across the page for clarity, it will be appreciated that, in use, the support member 18 does not move but remains attached to the wall 80 or supporting element via the mounting plate 12.

In the first stage of movement between a storage position and a working position, shown by the first and second left-most depictions of Figure 5, the second ends 54, 48 of the first and second link members 32, 40 move away from the wall slightly upwardly keeping the height of the distal side 82 of the frame 60 substantially constant through about the first 10 degrees of its travel. Since the pivot pins 52, 56 and thus the intermediate member 50 both move upwards slightly during this part of the operation of the mounting assembly 10, and the distal end 82 moves neither up nor down, it will be appreciated that the centre of mass of the frame moves slightly upwards during this part of the operation. This arrangement helps prevent the frame falling accidentally from the storage position to the working position. The mounting assembly thus does not require locking means in either the storage or working position.

It will also be noted that as the frame 60 approaches the working position, a convex engagement portion 102 at the second end 48 of the second link member engages a stop means in the form of a concave engagement portion 101 of the first member 32. This engagement prevents angular rotation beyond the working position. Furthermore, the illustrated arrangement provides a very strong and compact cantilevered support. It will be appreciated that a downwards force applied to the distal end of the frame 60 in the working position would tend to force the first link member 32 downwardly and the second link member 40 upwardly, but the engagement of the first and second link members 32, 40 allows transmission of force between them, resisting the forces applied by the frame 60. It is to be noted that the forces are effectively resisted at least in part because in the working position, the link members 32, 40 are arranged so that the first end of link member 32, attached to the support member 18 is above the second ends of the link members 32, 40 and the first end of the second link member 40 is below the second ends of the first and second link members . Having the second ends of the link members intermediate the first ends (vertically intermediate in the illustrated orientation, but other orientations are possible) is highly advantageous over other arrangements . It will be appreciated that the mounting assembly 10 is very compact. A prototype has been made which, in its storage position, extends only 100 mm away from a vertical support element to which it is mounted (corresponding to distance D in Figure 5) . The described structure enables even such compact link members to robustly support a working surface in cantilevered configuration.

Elements of a preferred embodiment will be described with reference to Figures 6 to 13. The elements illustrated in these drawings may have some differences to the corresponding elements in Figures 1 to 5 , but for convenience, corresponding reference numerals will be used except where stated otherwise.

Figures 6 and 7 are detailed views of intermediate member 50 from which it can be seen that walls 58 upstand from base portion 64 which is connected to top portion 66 of an attachment end or attachment portion of intermediate member 50 via a web 68. The web 68 is inclined relative to the base portion 64 and top portion 66 so that together the base portion 64, top portion 66 and web 68 have a cross-sectional shape, which is generally Z-shaped (with extended top and bottom bars) . A wall 70 extends downwardly from the edge 77 of the top portion 66 which is furthest from the web 68. The wall 70 is slightly narrower than the top portion 66 so that the wall 70 does not extend across the entire width of the edge 77, but leaves side portions 79 of edge 77 from which the wall 70 does not depend. The intermediate member 50 is arranged to receive box-section frame 60 and to be secured thereto by spot welds at points 72 and fillet welds at points 74. Thus, (considering the intermediate member 50 in the working position) the box section frame 60 is positioned vertically between parts of the base portion 64 and top portion 66 and laterally between parts of the walls 58 and the wall 70, and may be welded to each of these elements. Furthermore, the box section frame may be fillet welded to the edges of the web 68. Support plate 62 is spot welded to the wall 70 of intermediate member 50 at point 76. The engagement of the frame 60 to the intermediate member 50 is illustrated, to some extent in Figure 4.

Detailed views of the support member 18 are shown in Figures 8, 8A, 8B, 8C and 8D. Figure 8 is a front view; Figures 8A and 8B are cross-sectional views on 8A-8A and 8B-8B of Figure 8, respectively; Figure 8C is a side view and Figure 8D is a perspective view. In the embodiment of Figures 8 to 8D, as can be best seen in Figures 8B and 8D, the body portion 22 includes a central recessed central portion 22A which extends between the bottom edge of the body portion and the head portion 26 of the body portion

18, and an outstanding portion 22B on each lateral side of the recessed portion 22A. The recessed portion is arranged to be slightly wider in width than a mounting plate 18 with which the support member 18 is being used. Thus, the recessed portion 22A engages the mounting plate 18 and is wedged between the lugs 16 and the face of the mounting plate 12, and the outstanding portions 22B rest in contact with, or close to, the wall 80 or other support element to which the mounting plate 12 is attached.

It should also be noted that, as shown best in Figure 8D, one of the limbs 24 includes two circular apertures 25A and the other of the limbs includes two square apertures 25B, so that the pivot pins 28, 30 may be rotationally fixed by engagement of a portion with a square cross-section (not shown) with the square apertures 25B. In this embodiment, the support member 18 includes an additional aligned pair of apertures 19 which may be used for locating an accessory, such as a stand for an iron.

The support member 18 includes a pair of hook portions 9 one at each of the front bottom corners of the respective limbs 24, for use in suspending a cover when the mounting assembly 10, and ironing board or other apparatus attached thereto, is in use. The hook portions 9 have rounded extremities for safety. The upper corners of the limbs 24 which are distal from the body 22 are rounded for safety and so that as the mounting assembly 10 is moved from a working to a storage position, the likelihood of trapping objects between the frame 60 and the limbs 24 is reduced.

Detailed views of the mounting plate 12 are shown in Figures 9, 9A, 9B and 9C . Figure 9 is a front view; Figure 9A is a view from above; Figure 9B is a cross- section on 9B-9B of Figure 9 and Figure 9C is a perspective view. The apertures 14 are countersunk and upper corners 13 of the mounting plate 12 are rounded, to facilitate fitting of the support member 18. The lugs 16 each include a generally central, vertically extending strengthening ridge 17 and are slightly tapered to facilitate fitting of the support member 18. Since the mounting plate 12 is, in use, substantially covered by the support member 18, powder coating is not required and zinc plating is preferred.

Detailed views of the first link member 32 are shown in Figure 10A, which is a side view, and Figure 10B, which is a perspective view.

As described above, the first link member 32 includes a pair of link arms 34 joined by a body 36. It will be appreciated that in some embodiments the two link arms and the body may form a single block with a substantially uniform cross-section, and that the link arms 34 and body 36 may not be distinct or readily distinguishable from each other. It is also possible to have the body portion engage other elements of the mounting assembly as do the link arms, so that in such an embodiment, the link member could be considered as one very wide link arm. Such embodiments are not considered to fall outside the description of two link arms with a body extending therebetween. The important features are that the link member extends a substantial distance laterally and that two (not necessarily distinct) connected portions on opposing lateral sides of the link member each perform the function of a link arm. In the described embodiment, the lateral extent of the link arms is somewhat greater than their other dimensions, although this is not necessary in all embodiments. The first link member 32 of Figures 10A and 10B has lateral extent (into the drawing as seen in Figure 10A) of about 110 mm, a height (vertical dimension as seen in Figure 10A) of about 90 mm and a length

(horizontal dimension as seen in Figure 10A) of about 105 mm. As previously described, the first link member 32 has a shape which might be described as an open L-shape, that is the shape of a letter "L" but in which the angle between the two straight lines of the "L" is rather larger than 90 degrees. In the embodiment of Figure 10A, this angle is about 125 degrees. At the outside of the corner thus provided, the first link member includes a concave engagement surface for engaging the second end 48 of the second link member 40 when the mounting assembly 10 is in the working position.

The considerations above relating to the link arms and body portion of the first link member 32 also apply to the second link member 40. The second link member 40 is shown in detail in Figure 11A, which provides a side elevation and Figure 11B, which provides a perspective view. As described earlier, the second link member 40 has a first end 46 and a second end 48 and, in this embodiment, includes a distinct pair of link arms 42 with a body portion 44 therebetween. The portions of the link arms 42 at the second end 48 of the second link member 40 form convex engagement portions 102 which, in use, engage with the concave engagement portions 101 of the first link member 32 when the mounting assembly 10 is in its working position. As can be seen in Figure 11A, in this embodiment the second link member 40 includes on each link arm 42 an additional engagement portion 103 in the form of a groove which, in use, receives and engages a link engagement portion in the form of the rear edge 64A of the bottom portion 64 of the intermediate member 50. When the apparatus is in its working position, the continuous rear edge is securely located in the laterally spaced apart grooves in the two link arms 42 and its vertical movement is restricted by this location, providing resistance to torsional forces . This helps provide a further degree of stability to the mounting assembly 10. In a preferred embodiment, the mounting assembly is for use with a foldable ironing board, and may include a cover for use when the ironing board is in its storage configuration. Figures 12A to 12E illustrate the use of such an ironing board including the cover . Figure 12A illustrates the removal of an ironing board cover 110 from a foldable ironing board assembly 120. The ironing board cover 110 is removed from its position on the ironing board assembly 120, where it is retained by engagement of a top edge of the cover 112 on a frame portion 122 of the ironing board assembly 120, which is adapted for the purpose.

As shown in Figure 12B, the cover 110 can then be engaged on the hook portions 9 of the support member 18 for convenience storage while the ironing board is in use. The cover 110 includes engagement portions 114 to engage the hook portions 9. As shown in Figure 12C, once the cover 110 is conveniently stored on the hook portions 9, the ironing board assembly 120 may be moved from its storage position to a working position by operation of the mounting assembly 10, and then operation of a generally central hinge of the ironing board. Figure 12D shows, from below, the ironing board assembly 120 in its unfolded configuration with the cover 110 shown in its storage position. As shown in Figure 12E, the ironing board assembly 120 preferably allows the ironing board to rotate in a horizontal plane so that it can be placed in a convenient operating position.

Figure 13 is a perspective view from above of an ironing board assembly (without fabric cover) in its working position. An iron stand 130 is provided by attachment of ends of the metal frame from which it is formed in the apertures 19 of the support member 18. The stand 130 pivots about these apertures for storage, and is supported in a substantially horizontal working position by engagement of stop members 131 on the upper edges of the limbs of the support member 18.

It is to be appreciated that the mounting assembly 10 may be used with articles other than folding ironing boards. The provision of an intermediate member 50 to which the first and second link members 32, 40 are pivotally attached allows great flexibility of function, since a box section metal frame may be easily attached thereto, and an appropriate frame may underlie an ironing board, a table, a clothes airier, or one of many other pieces of equipment which might advantageously be moved from a working position to a storage position by use of the mounting assembly 10.

Use of a cover 110 provides an aesthetically pleasing finish when equipment is in its storage position, and the mounting assembly 10 allows a narrow profile. Furthermore, if desired, the mounting member 18 may be easily removed by lifting it away from the mounting plate 12 and the mounting assembly as a whole may be stored in a different location.

Using the mounting plate -12, mounting of the assembly 10 to a wall is easy and convenient since the mounting plate 12 need only be screwed to a single stud of the wall or other support element. Many prior art mounting arrangements require a number of members to be mounted to a support element, or require a cabinet or special mounting frame to be attached to the wall. The provision of short but relatively wide link members provides good resistance to unwanted wobble and twist and enables a single mounting assembly to support a working surface rather than requiring two spaced apart mounting assemblies .

The provision of a support member 18 with limbs 24 effectively houses the link members 32, 40 providing an aesthetic and well supported linkage system.

Although it is envisaged that the mounting assembly 10 will normally be used in the orientation shown in Figure 5, that is with the first link member 32 positioned generally above the second link member 40 and operating a member to which the link members 32, 40 are attached from a vertical storage position to a horizontal working position, other orientations are possible as will be appreciated from the disclosure of Figures 11 to 13 of PCT/AU96/00443.

Modifications and improvements may be incorporated without departing from the scope of the present invention.

Throughout this specification and the claims, the words "comprise", "comprises" and "comprising" are used in a non-exclusive sense, except where the context requires otherwise .

It is to be understood that, if any prior art publication is referred to herein, such reference does not constitute an admission that the publication forms a part of the common general knowledge in the art, in Australia or in any other country.
