Description

[0001] BASE

[0002] TECHNICAL FIELD

[0003] This disclosure relates to an assembly for supporting an object on a surface. The disclosure is particularly directed toward a base for supporting and stabilising an object on a surface, the base being adapted to allow a variety of supports including glides, stabilising supports and feet to be inserted therein to support the object.

[0004] BACKGROUND

[0005] Table legs and other objects such as furniture or commercial or household items are frequently provided with protective mounted ends or supports that enable the table or other object to be moved without damaging the floor or the legs of the table. Generally speaking, these supports are coupled to the legs of a table base and may be provided integrally in the leg or attached separately to the leg such as by screwing, sticking using adhesives etc. In some cases, the table may have multiple separate legs and in other cases, the table may have a single large leg base which may comprise different shapes (circular, rectangular, square etc.) to which supports are coupled at different points as required.

[0006] The supports may include a simple solid support (known as a glide) made of rubber / plastic that only acts to protect the surface on which the table is resting from damage. Alternatively, the support can be a stabilizing / levelling attachment (e.g. a hydraulic stabiliser) allowing a user to adjust the height of the table and / or level it or any other leg or foot. For example, such attachments may enable one to use the table on an uneven floor preventing the table from wobbling. Similarly, when multiple tables are put together, the alignment between the various surfaces may not be uniform and even. The attachments can assist in adjusting the height of one or more legs of the table in order to bring the table tops of the various tables to the same height thereby enabling alignment. Such attachments may also help protect the floor from damage as well by the tables.

[0007] Both glides and stabilising attachments are typically fixed to the table legs through screwing or other means such that they are separable from the table. This has the benefits of facilitating easy replacement and allowing for a change in foot shape, function or appearance. However, such a connection between the glide / attachment and the table leg is susceptible to damage when the tables are moved along the floor. Any such damage may require the attachment / glide to be replaced thus increasing costs associated with repairs and tables. Furthermore, such a method of fixing may also require a user to drill a threaded hole into the legs of the table. Accordingly, it is desirable to have alternative connection systems that display improved performance. Similarly, depending on the height of the support used, the aesthetics of the table may be affected (e.g. large supports may be distinctly visible below the base). It is therefore desirable to have the attachment or the glides less visible for the sake of improving aesthetic appeal of the tables.

[0008] SUMMARY

[0009] It is desirable to provide a base such as a table base that allows for the use of multiple support systems or multiple stabilising / levelling / protection systems in the form of glides, feet, stabilisers or any support system that sits between the base and the surface on which the base sits. It is desirable that the support systems be interchangeable and that such a base provides protection for the feet or stabilisers, limits bending and sheer forces on the support systems, provides aesthetically pleasing options, and / or enables exchanging one support or stabiliser for another kind of support or stabiliser as needed.

[0010] Disclosed is a base for interchangeably attaching multiple support alternatives to a table or similar object, the base comprising a plurality of support retainers located within or extending from the base, the retainers comprising side walls defining a retainer cavity and comprising an attachment element located within the retainer cavity, the shape and configuration of the retainer being adapted to allow a foot support to be connected with the attachment element within the retainer cavity such that in use a significant portion of the foot support is located within the retainer cavity of the base. In some forms the retainer has a domed shape. The base in some forms also has the benefit of allowing differing supports to be utilized in different tables, while maintaining a similar height between the tables by maintaining a consistent distance between a lower surface of the support and a lower surface of the base. This has aesthetic benefits and practical use benefits. Distributors and dealers often need to stock different types of bases that are used with different types of supports and respective accessories (e.g. table posts / rods, top plates etc.) that are tailored to specific types of supports. Given the various types of supports in demand in the market, distributors / dealers who wish to cater to the varied requirements are often required to store (large) quantities of the different types of bases and associated supports / accessories. Given that some of the components (e.g the base, table posts / rods) would occupy significant space, the distributors / dealers are often forced to employ large warehouses to provide sufficient space to store the different components. The problem is compounded given that there are also different sizes of bases available for each type of support. The base of the present invention provides the ability to accommodate different types of supports in a single base (i.e. it is enough to have just one type of base rather than multiple types of bases). As a result, the need to store different types of bases for different types of supports is reduced or eliminated. Similarly, the need to store different types of accessories (i.e. specific to each different type of support) is also reduced or eliminated. Thus, the storage space required can be significantly reduced by using a base that can accommodate different types of supports.

[0011] Another advantage of the base is that it can offer customers flexibility and savings in terms of costs. For example, a customer may choose to use a combination of supports such as glides for one table and stabilizing attachments for other tables etc. while not having to worry about using different bases for each. Similarly, in the future, if a customer wishes to upgrade (e.g. change all glide supports to a stabilizing attchment), then they can do so by simply ordering the support alone rather than the entire base and other accessories.

[0012] In a first aspect, disclosed herein is a base for interchangeably attaching one or more supports for supporting a table or similar object on a surface, the base comprising a base body and a plurality of support retainers located within or extending from the base body; the support retainers comprising: an upper wall and one or more side walls defining a retainer cavity; and an attachment element located within the retainer cavity; the shape and configuration of each support retainer being adapted to allow a support to be engaged with the attachment element within the retainer cavity such that in use with the supports supporting the table or object on a surface, a substantial portion of the support is located within the retainer cavity. Such a base allows multiple types of supports to be fitted to the same base without having the need to remove / replace the base.

[0013] In some forms, the attachment element comprises a bore or threaded hole configured to receive a corresponding connecting element associated with the support to facilitate engagement of the support with the attachment element.

[0014] In some forms, at least a portion of the attachment element extends into the upper wall of the retainer cavity. This creates more space within the retainer cavity to locate a substantial portion of the support.

[0015] In some forms, the attachment element comprises an abutment surface that is located in the retainer cavity.

[0016] In some forms, the abutment surface comprises a planar face spaced apart from the upper wall and facing downwardly from the upper wall in use.

[0017] In some forms, the abutment surface is composed of a lower face of a projection projecting from the upper wall into the retainer cavity.

[0018] In some forms, the projection is located around at least a portion of a perimeter of the attachment element. Such an arrangement creates additional points of contact between the attachment element and the support thereby reinforcing the support and preventing it from bending / flexing under the influence of lateral forces.

[0019] In some forms, the projection comprises two corresponding C-shaped projections extending around the perimeter of the attachment element.

[0020] In some forms, the C-shaped projections are mirror images and are spaced apart from one another to form a broken annular projection around the attachment element. Such an arrangement can, in addition to providing additional points of contact, assist with positioning of the support in a desired orientation within the retainer cavity.

[0021] In some forms, the retainer cavity is defined by the upper wall, one or more side walls, and an opening.

[0022] In some forms, the opening is configured to face toward a central region of the base. Such an arrangement allows for connections to be provided between a central portion of the base and the support. For example, pipes that transfer hydraulic fluids may be connected between supports located at the ends of respective arms of the base and the central portion. In this manner, various supports may be connected together.

[0023] In some forms, the connecting element may be connected to or form part of the support. This may facilitate a direct connection between the support and the attachment element without the need for other components / accessories.

[0024] In some forms, the retainer cavity is configured to receive a sleeve that is configured to be located between the support and the retainer cavity and to receive the support to be engaged with the attachment element. The sleeve may provide additional reinforcement to the walls of the support and prevent the support from being damaged due to forces acting on it when the table is moved along a surface.

[0025] In some forms, an inner surface of the side walls of the retainer cavity comprises at least one groove that engages with at least one corresponding projection located on an outer surface of the sleeve. Such grooves may facilitate positioning of the sleeve within the retainer cavity and prevent its rotation within the cavity.

[0026] In some forms, an outer surface of the sleeve comprises a corresponding recess configured to receive the abutment surface.

[0027] In some forms, the sleeve comprises a cut out section on a side wall of the sleeve. This cut-out section can facilitate connections to be provided between a central portion of the base and the support.

[0028] In some forms, the sleeve comprises a securing attachment to which the support can be fastened. This may prevent the support from falling out of the sleeve.

[0029] In some forms, the connecting element is connected to or part of the sleeve.

[0030] In some forms, each support is in the form of a hydraulic device configured to adjust height and / or stabilize the table or other object.

[0031] In some forms, a plurality of supports located in the plurality of retainers are hydraulically connected to each other.

[0032] In some forms, the support is in the form of a non-hydraulic adjustable support.

[0033] In a second aspect, disclosed herein is a kit for retrofitting tables with a base, the kit comprising: a base as defined hereinabove and a support as defined hereinabove.

[0034] In a third aspect, disclosed herein is base for interchangeably attaching one or more supports for supporting a table or similar object on a surface, the base comprising a base body and a plurality of support retainers located within or extending from the base body; the support retainers comprising: an upper wall and one or more side walls defining a retainer cavity; and, an attachment element located within the retainer cavity; the shape and configuration of each support retainer being adapted to retain various supports with a variety of shapes and functions within the retainer cavity while maintaining a substantially consistent distance between a lower surface of the support and a lower surface of the base.

[0035] In some forms, the support retainer is adapted to retain multiple hydraulic supports, a hydraulic support system comprising a plurality of supports hydraulically connected with one another a non- hydraulic adjustable support or a fixed support. FIGURES

[0051] DESCRIPTION

[0052] In the following detailed description, reference is made to accompanying drawings which form a part of the detailed description. The illustrated embodiments described in the detailed description, depicted in the drawings are not intended to be limiting. Other embodiments may be utilised and other changes may be made without departing from the spirit or scope of the subject matter presented. It will be readily understood that the aspects of the present disclosure, as generally described herein and illustrated in the drawings can be arranged, substituted, combined, separated and designed in a wide variety of different configurations, all of which are contemplated in this disclosure.

[0053] In some forms the present invention provides a table base that can accommodate glides or stabilising attachments in an interchangeable manner while improving the protective value and aesthetic appeal of the base.

[0054] Referring to Figure 1, disclosed is a table base 10 for interchangeably attaching one or more supports for supporting a table or a similar object on a surface. The table base can be fixed to a table top through an appropriate post to support the table top above the surface. The table base can take any desirable shape and configuration depending on the aesthetic and functional requirements. The table base 10 can be sized appropriately to support the weight of the table top and the post. The table base 10 is configured such that various types of supports such as glides, stabilizing supports (such as hydraulic, pneumatic devices) or feet may be attached to it in an interchangeable manner. For example, a user using a table using the base 10 with glides as the supports and wanting to change the glides to another type of support can simply remove the glides from the base 10 and then fit stabilizing supports in place of the glides.

[0055] The table base 10 in the illustrated form, comprises a base body 1 and a plurality of support retainers 5 located within or extending from the base body 1. The base body 1 provides a structure capable of accommodating components (e.g. support retainers) and load bearing capability to the table base 10 and can take different forms. For example, the base body 1 may be formed as a single continuous piece (such as a solid piece of metal / plastic or alternatively a hollow solid piece of metal / plastic etc.) or formed as a skeletal structure (e.g. multiple arms connected to a central portion or each other). The base body 1 can further take any suitable shape such as circular, square, rectangular etc. The plurality of support retainers 5 can be located within the perimeter of the base body 1 and / or extend from the perimeter of the base body 1. In the illustrated embodiment, the base body 1 includes a plurality of arms 2 extending from a central portion 3 to an end 4. Each of the arms 2 includes a support retainer 5 located within an end portion of the arm 2. The arms 2 are designed to support the table and allow multiple foot support alternatives to be utilised in the same shaped base. The arms 2 help distribute the weight of the table equally on the floor in 4 directions thus helping provide stability. In the illustrated embodiment, there are 4 arms extending at 90° to each other. It will be understood that the number of arms and the spacing could be varied as desired. For example, the base can also include 3 arms spaced at 120° to each other or the base can include 2 arms spaced at 180° to each other.

[0056] Support Retainer

[0057] Referring to Figure 2, the support retainer 5 is shaped and configured to allow the insertion and retention of one of a plurality of supports in the form of glides, stabilising supports or feet (not shown in figure 1).

[0058] More specifically, the support retainer 5 comprises one or more side walls 6e, 6f and an upper wall 7 which together define a retainer cavity 8. The dimensions of the side walls 6e, 6f and upper wall 7 are chosen such that the retainer cavity 8 is capable of housing a substantial portion of the support. In this manner, the support retainer provides external protection and internal support through the side walls 6 and upper wall 7 which have sufficient thickness and shape. In the illustrated form the side walls extend around three sides of the retainer cavity and comprise an end side wall 6e and two facing side walls 6f. In this form the end side walls 6e, 6f extend from the upper wall 7 and slopes away from the upper wall towards the surface on which the base is supported. In some forms more than half of the support is located within the retainer cavity 8 thus allowing the support to be hidden largely within the retainer cavity 8.

[0059] In the illustrated embodiment, support retainer 5 is in the form of a cut out or hollowed out shell portion extending upwardly into the end 4 of the arm. In the illustrated form the support retainer 5 has a curved upper surface although alternative shapes are within the scope of the disclosure.

[0060] In some forms, more than one retainer may be provided in an arm. This may allow the use of more than one support in each arm. For example, each of the arms 2 may comprise more than one support retainer 5 at different locations - for e.g. one at the end and one along the middle of the arm 2. In this manner, more than one support can be provided per arm thus greatly increasing the load carrying capacity and / or stability of the table. It will be appreciated that in such a case, the retainers used in the same arm may have different shapes. For example, a retainer used in the middle portion of the arm may not be shaped like a retainer used at the end portion of the arm. The location and number of retainers may be varied as per requirements.

[0061] The support retainer 5 may be formed from the same material as the base body 1. Alternatively, the support retainer 5 may be formed from a material that is different from the material of the base body 1. The material of the base body 1 and the support retainer 5 can be made from materials such as plastics or metals or alloys.

[0062] In the illustrated embodiment, the support retainer 5 is formed integral to the base body 1 (and thus can formed during the manufacturing of the base body 1). However, it will be appreciated that the support retainer 5 can also be formed as a separate component that is affixed to the base body 1 through suitable means (such as adhesives for example).

[0063] In some forms, the retainer cavity 8 of the support retainer 5 has an opening. This opening can facilitate connection between supports located at different sections of the base body 1. For example, in a base body 1 having 4 arms, the supports located at each arm can be connected to each other / a central portion via fluid lines. Such a configuration allows for a stabilizing system to be incorporated into a base (discussed further below). In the illustrated embodiment, this opening may face towards a central region of the base.

[0064] Attachment element

[0065] To facilitate the support retainer 5 to receive and retain the support in a secure manner, the support retainer 5 comprises an attachment element 9 located within the retainer cavity. In its simplest form, the attachment element 9 can be a surface that facilitates attachment between a support and the support retainer 5. For example, a surface of the support may be affixed to the upper wall 7 of the support retainer 5 using replaceable adhesives, screws, or other means of removably engaging the support to the support retainer.

[0066] In the illustrated embodiment, the attachment element 9 is in the form of a threaded hole 11. The threaded hole 11 is configured to receive a connecting element (not shown) associated with the support to facilitate engagement of the support with the attachment element 9. Thus, the support (or a sleeve associated with the support) has a threaded screw portion that can engage with the threaded hole 11. Alternatively, a separate screw may also be used (i.e. independent of the support or an associated sleeve) as the connecting element.

[0067] It will be understood that the attachment element can also take other forms such as a bore (i.e. a plain hole instead of a threaded hole 11). In this form, the corresponding connecting element will be received in the bore to facilitate an interference / clearance fit to secure the support to the support retainer 5.

[0068] In some forms, a part of the bore / threaded hole 11 discussed above extends into the upper wall 7 (as best shown in Figure 2) of the retainer cavity 8. The thickness of the upper wall 7 will thus be chosen accordingly to ensure that the upper wall 7 meets the functional and aesthetic requirements.

[0069] Abutment Surface

[0070] In some forms, the attachment element 9 comprises an abutment surface 13 that is located in the retainer cavity 8. The abutment surface 13 functions as a surface that contacts a portion of the support (or sleeve associated with the support) so as to increase the extent of contact occurring between the support and the support retainer 5. In this manner, the abutment surface can provide additional support to the engagement established between the support and the support retainer 5. For example, the abutment surface 13 (see Figure 2) surrounding the attachment element 9 can engage with a washer or surface of a support / its sleeve. This increases the amount of contact occurring between the support and the support retainer thereby resulting in a more stable connection. Such an arrangement can have other benefits as well. For example, the increased thickness of the upper wall resulting from the abutment surface means connecting element is limited from bending when the table base is moved horizontally. The size of the abutment surface may be configured depending on the extent of contact desired and the configuration of the supports / acces series used. Similarly, the abutment surface may take any suitable form. For example, the abutment surface may be in the form of a projection or a planar surface (discussed further below) or a recess in the attachment element 9.

[0071] In some forms (best seen in Figure 2), the abutment surface 13 comprises a planar surface that is located within the cavity spaced apart from the upper wall 7 and facing downwardly from the upper wall 7. Depending on the configuration of the support / connecting element etc., the extent by which the planar surface is spaced apart from the upper wall 7 may be varied. For example, the planar surface may be located further away for a connecting element that is longer. It will be appreciated that this distance between the planar surface and the upper wall will also be dictated by the requirement to cover a substantial portion of the support within the retainer cavity 8.

[0072] Projection

[0073] In some forms, the abutment surface 13 can be formed as a planar surface comprising the lower surface of a projection 13a projecting from the upper wall 7 into the retainer cavity 8 (as best seen in Figure 2). In the illustrated embodiment, this projection is located around at least a portion of a perimeter of the attachment element 9. As best seen in Figure 2, this configuration allows the abutment surface 13 to contact a surface of the support as well as a portion of a connecting element that is located outside the threaded hole 11 of the attachment element 9. Thus, additional points of contact are created between the support and the support retainer as discussed above. In addition, the projections may also assist with positioning of the support / an associated sleeve. For example, a sleeve associated with the support (described further below) may have a corresponding recess configured to receive the projection.

[0074] In the illustrated embodiment (shown in Figure 2), the projection comprises two C-shaped projections that extend around the perimeter of the attachment element and are mirror images of each other that are spaced apart from another to form a broken annular projection around the attachment element 9. The broken annular projection can also prevent rotation of the support / sleeve associated with the support. Taking the example of a sleeve associated with the support locating on this projection, it is possible to provide a projecting member / members on the sleeve that can be received in the recess created by the broken annular projections (i.e. between the two C-shaped sections). Once located and secured in this configuration, if the sleeve encounters any type of rotational movement, it will be prevented from rotating because of the projecting member being blocked by the walls of the C-shaped section provided.

[0075] Sleeve

[0076] As discussed earlier, the base 1 may be configured to receive multiple types of support. In this regard, certain types of support may be smaller than the retainer cavity 8 or other types of supports. For example, hydraulic supports may come in different configurations (such as connected hydraulic supports or independent hydraulic supports). The different configurations may be sized and / or have different operational principles. Accordingly, in order to provide interchangeability, a sleeve (28 / 28’) can be provided (see Figures 3 A - 3C). The sleeve (28 / 28’) can be received within the retainer cavity 8 and be secured to the support retainer 5. The support can in turn be received and secured within the sleeve and thus be engaged with the attachment element 9 through the sleeve. When the support is received within a sleeve, the support is limited from any rotation or lateral movements. For example, when a user inadvertently moves the table base along the surface, then such a lateral movement does not cause the support to bend relative to its connection with the support retainer 5 thereby leading to a failure of the connection. Thus, the sleeve (28 / 28’) also functions to provide additional protection to the support.

[0077] In the illustrated form, the sleeve has one or more side walls 28a and a top wall 28b connecting the side walls. In the illustrated embodiments, the side wall is generally circular with one top wall. However, it will be appreciated that the side walls and top walls need not be fully solid. For example, each of the side walls could simply be formed as two separate posts comprising a a cavity therebetween and connected along an edge of the cavity only (similar to how a chair with 4 legs is connected only along the seat areas).

[0078] The shape and configuration of the sleeve 28 would depend on the profile and dimensions of the retainer cavity as well as the support to be located within the cavity. For example, if the support to be engaged with the support retainer 5 is significantly smaller than the retainer cavity 8 then a sleeve with thicker side walls and / or top walls may be utilized. It will be apparent to a person skilled in the art to make suitable modifications to the size and shape of the sleeves as desirable.

[0079] The outer surface of the sleeve and the inner surface of the retainer cavity 8 may have complementary features that engage with each other to prevent rotation of the sleeve 28. For example, an inner surface of the side walls of the retainer cavity 8 comprises at least one recess / groove 14 (best shown in Figure 2) that engages with at least one corresponding complementary projection 14a (best seen in Figure 3A) located on an outer surface of the sleeve 28. It will be understood that any number of such grooves / recesses may be provided on the retainer cavity 8 and any number of corresponding complementary projections may be provided on the sleeve 28. Similarly, it will also be understood that the recess / groove may be located on the sleeve 28 with the corresponding complementary projection being located on the inner surface of the retainer cavity. Furthermore, the features may take any suitable shape and size that satisfy the functional requirements (i.e. preventing rotation of the sleeve within the cavity and accommodating the support within). The resulting fit between the sleeve 28 / 28 ’ and the retainer cavity 8 is such that the sleeve is generally unable to move significantly after it is secured to the retainer cavity 8. It will be understood that appropriate tolerances may be provided to ensure that the fit between the sleeve 28 and the retainer cavity 8 allows for easy insertion / removal of the sleeve from the retainer cavity 8.

[0080] To receive and secure the support within, the sleeve 28 / 28’ may also comprise a securing attachment 31 (best seen in Figure 3 A). In the illustrated embodiment, the securing attachment 31 comprises a threaded hole 31a that is configured to receive a fastener that secures the support together with the sleeve 28. It will be understood that the connection between the sleeve and the support may be accomplished through other means as well such as using adhesives / sui table clips etc.

[0081] In some forms, the sleeve can also have other additional features. Referring to the embodiments illustrated in Figures 3B to 3C, the sleeve comprises a connecting element 30’ (described further below) that engages with the attachment element of thus facilitating the connection of the support to the attachment element 9. In other forms, the sleeve 28 may simply have an aperture 30 that is configured to receive a separate connecting element (best seen in Figure 7A, 7B which discloses a similar sleeve 280’) which secures the sleeve 28 to the retainer cavity 8.

[0082] Connecting element

[0083] As briefly mentioned above, the support and / or the sleeve are connected to the support retainer 5 in order to locate the support within the retainer cavity 8. In this regard, a connecting element 30 / 30’ can be used to accomplish this connection. The connecting element functions to couple the support to the attachment element 9 either directly or indirectly (i.e. through the sleeve 28 discussed above).

[0084] In some forms, the connecting element comprises a threaded screw section that may either be coupled to the sleeve (Figure 3B), or formed as part of the support itself or be a separate component (Figures 7A-7B).

[0085] In other forms, when the support is a glide / independent hydraulic support coupled to the support retainer 5, the connecting element may be formed as part of these components. As best shown in Figure 12A-12B, the hydraulic support comprises a piston, an end of which comprises the threaded screw 430’.

[0086] In still other forms, the connecting element 30 / 30’ may be in the form of a projecting member that is configured for interference / clearance fit with an attachment element 9 in the form of a bore extending into the upper wall 7 of the support retainer 5. Type of hydraulic supports

[0087] As briefly described in various sections, the support is the component that rests on the surface and performs the load bearing and other functions such as height adjustment, providing stability etc. Supports can be of different types. In the simplest form, the supports may be fixed, non-adjustable support such as a glide or foot. Such supports simply perform the load bearing function but may not provide any adjustability with respect to the height or stability of the tables.

[0088] In some forms, the supports can include non-hydraulic adjustable supports (such as spring-based supports).

[0089] Where adjustment of height or stability is required, hydraulic supports may be employed. Hydraulic supports may be of two types - connected and independent. Connected hydraulic supports include supports that are connected to each other through hydraulic lines allowing fluids to flow from one support to another in response to changes in pressure. For example, in the illustrated embodiment (shown in Figures 4 and 5), each of the adjustment posts 180 comprises a hydraulic stabilizing mechanism comprising a hydraulic fluid housed in a bladder. When fluid moves into the bladder, the size of the bladder increases thereby increasing the height of the adjustment post. Similarly, when fluid moves out of the bladder, the height of the adjustment post decreases thereby decreasing the height of the bladder. The bladders are fluidly connected to the pipes 220 through which hydraulic fluid in the posts 180 can be moved into and out of the bladder when pressure is applied to the post. This is especially useful in situations where surfaces that the tables sit on are not even or where more than one table is required to be aligned to each other.

[0090] Independent hydraulic supports on the other hand include supports such as those disclosed in Australian Patent application Number: 2016903071, the contents of which are incorporated herein in entirety.

[0091] Kits

[0092] In some forms, disclosed herein is a kit comprising parts that would allow an existing table to be retrofitted with the base of the present disclosure. The kit includes a base attachable to a table or other object, the base being as described herein above. The kit further comprises a hydraulic support as disclosed above. The kit in some forms further comprises multiple forms of hydraulic support and / or multiple forms of support. Thus, a user can simply remove the base of an existing table and retrofit the base of the present disclosure. It will be understood that the kit may also include other components such as fasteners, washers and tools for retrofitting etc. that facilitate the process of retrofitting.

[0094] The sections below detail various embodiments of the base in use with different types of supports.

[0095] Referring to Figs. 4 - 6, disclosed is a table base 100 that allows for insertion and retention of a stabilising system. In this embodiment, a base 100 includes a base body 120 comprising 4 arms 140 that extend outwardly from a centre of the base body 120 and are angularly spaced at 90° with respect to each other.

[0096] Each end of the arms 140 comprises an end segment 240 (see Figures 4 and 5) which houses a support foot in the form of a stabilising adjustment post 180 that is in contact with the floor. In this support system there are in total 4 adjustment posts 180 that are fluidly connected through pipes 220.

[0097] The end segments 240 comprise a support retainer in the form of a dome portion 260 that sits flush with the arm 140. The dome portion 260 comprises a re t ai ner c av i t y i n th e form o f a hollow portion (not shown) that is configured to receive a sleeve 280 (see Figures 5 and 6). The dome portion 260 is defined by side walls and is sized so that it houses a substantial portion of the post 180 and the entire sleeve 280. This results in an aesthetically improved appearance for the base 100 in which much of the post 1 80 is not visible unless inspected closely. The side walls of the dome are shaped to abut the sleeve to provide additional support. An upper platform 330 is located within the dome to provide a flat surface against which the support or stabilising foot bears.

[0098] The sleeve 280 is configured to receive the adjustment post 180. The sleeve 280 functions to close the gap between an inner wall of the dome portion 260 and the adjustment post 180. Specifically, an outer surface of the sleeve is in contact with a surface of the inner wall of the dome portion 260 and an inner surface of the sleeve 280 is in contact with an outer surface of the adjustment post 180. The contact areas between the post 180 and the sleeve 280 is substantial so as to ensure that there is very little or no relative movement of the post 180 with respect to the sleeve 280.

[0099] To secure the post 180 to sleeve 280, the sleeve 280 is provided with a standard hole (for e.g. a hole that can receive a self-threadingscrew ) on a section of its wall. A projection (not shown) is provided on the post 180. The projection has an aperture that corresponds with the standard hole provided on the sleeve 280. In use, a self-threading screw can be used to secure the sleeve 280 and the post 180 together. The size and nature of the screw can be varied. For example, bigger screws can be used to couple bigger sized supports with bigger size sleeves. Similarly, the hole may also be provided as a threaded hole (i.e. threads are already provided in the hole) and suitable threaded screws (non-self threading) may be used to couple the post 180 with the sleeve 280.

[0100] The sleeve 280 also has 3 grooves (not shown) on its internal surface that is in contact with the outer surface of the post 180. The outer surface of the post 180 has corresponding tabs (not shown) that can be received into the grooves located on the sleeve 280. Together, the tabs and grooves prevent rotation of the post 180 relative to the sleeve 280 in use. The tabs / grooves are spaced around the circumference.

[0101] As discussed above, the sleeve can take at least two forms. In the first form, the sleeve 280 has a threaded screw 300 (shown in Figure 6) that is used to secure the sleeve 280 to the dome portion 260 of the end segment 240. The dome portion 260 has a corresponding threaded hole 320 that receives the screw 300 of the post 180.

[0102] The sleeve 280 also comprises a cut out section (not shown) which allows for outlets 340 located on the post 180 to be connected with pipes 220 so as to facilitate transfer of hydraulic fluids. The cut out sections can be sized as desired depending on the number, shape and configuration of the outlets provided on the post 180.

[0103] The sleeve 280 further comprises tabs 34’ (best seen in Figure 3C) located on a top surface. The dome portion 260 has corresponding tabs located on a top inner surface (not shown). The tabs 34’ provide an indication of the locking state of the post 180 with respect to the sleeve 280 (described in detail below) and prevents overtightening of the screw 300 of the sleeve 280. In other words, the sleeve can be rotated until the tab located on the dome portion 260 is trapped in between the tabs 340 of the sleeve.

[0104] A user wishing to assemble the end segment 240 can follow the below steps:

[0105] The sleeve 280 is first inserted into the dome portion 260 of the hollow sleeve such that the screw 300 of the sleeve engages the threaded hole 320 of the dome portion 260. The sleeve is screwed on by rotation until the one of the tabs 340 engages the tab located on the top inner surface of the dome portion 260. A click sound is heard once the tab of the dome portion is trapped in between the tabs 340 of the sleeve. At this stage, the sleeve 280 will be secured to the dome portion 260. Next, the adjustable post 180 is inserted into the sleeve 280 by aligning the tabs on the post 18 with the grooves on the sleeve 280.

[0106] Once aligned, the post 180 and sleeve 280 are secured together using the self- threading screws. This step completes the assembly of the end segment 240.

[0107] Subsequently, the end segment 240 can be coupled to the support structure 120 to complete assembly of the base 100.

[0108] In a second form, the sleeve 280’ comprises (as best seen in Figures 7A, 7B and 8) an aperture 300’ instead of a threaded screw portion 300. A separate threaded screw 300a’ can be received into this aperture to secure the sleeve 280’ to the dome shaped portion. All the above steps of assembly described above are equally applicable for the sleeve 280’ as well. The slight difference in the first step will be obvious (e.g. the user simply needs to insert the sleeve 280’ first into the dome shaped portion and then fasten it using the threaded screw 300a’). In one variation of the second form, an underside of the bolt head and a surface of the sleeve 280’ which comes into contact with the underside of the bolt head are serrated to ensure locking of bolt to the sleeve during the final tightening process during assembly. This can prevent bolt loosening during usage. Similarly, the upper surface of the sleeve 280’ can also be serrated so as to provide a locking effect when it comes into contact with the upper wall of the retainer cavity to minimize any lateral movement of the sleeve 280’ the base after tightening. This acts as a negative lock through the angle of the serrations of the insert.

[0109] Referring now to Figures 9 to 12B, disclosed is a table base 400. Like parts will be identified using like reference numerals in this section.

[0110] In this base, the adjustment post 480 comprises an independent support which is extendible and retractable. The adjustment post 480 of the present embodiment also comprises a hydraulic mechanism that allows for adjustment of the height of the post. However, there are no bladders and pipes 220 to transfer hydraulic fluid in and out of the post depending on the pressure applied to the post. Instead, the post 480 comprises a device that is described in Australian Patent application Number: 2016903071, the contents of which are incorporated herein in entirety.

[0111] The post 480 can be secured directly to the dome shaped portion 260 unlike the previous embodiment where a sleeve is employed to reinforce the connection between the post 180 and the dome shaped portion 260. In this embodiment, a screw 430’ is provided on the post 480 which is able to engage the threaded hole 430 provided in the dome shaped portion 260 to secure the post 480 to the dome portion 260. As best seen in Figures 12A-B, a washer 430a may be used to facilitate the connection and prevent damage to the raised platform of the attachment element.

[0112] The dome shaped shell portion 260 is sufficiently deep to allow a significant portion of the post 480 to be protected and hidden therein. The side walls of the dome shaped portion provide additional support by abutting the post to strengthen the connection and limit bending and shear forces on the post.

[0113] With reference to Figure 13, disclosed is another embodiment of the base using the hydraulic support 480. In this embodiment, each of the arms 140 of the base body 120 has the ability to fix more than one hydraulic support 480. For example, two supports 480 may be located on each of the arms 140. As shown in Figure 13, the location may be at approximately the middle section of the arm 140. It will be appreciated that the location and number of supports may be varied as desired. As disclosed above, increasing the number of supports can offer improved load carrying capability. It should be noted that multiple supports can also be fixed to bases that do not have arms and are instead formed from one continuous solid piece. For example, a base that is circular in shape and typically has 5 hydraulic supports 480 can be fabricated in such a manner that an additional supports 480 can be added to the base if desired.

[0114] Referring to Figures 14A-B, disclosed is a third type of support - a glide 580 that may be used with a table base. The glide does not have a hydraulic heigh adjustment capability and simply acts to support the table leg on the floor. The structure of the base is essentially the same as that described above and includes a base body 120 comprising arms 140 with end segments 240 comprising a dome shaped portion 260. The glide 580 can be secured to the dome shaped portion 260 through a washer / nut 530a. The glide 580 comprises a screw shaped projection 530 that can be received within the attachment element of the dome shaped portion 260 (as best seen in Figure 14A).

[0115] Disclosed in Figures 15A - E are different embodiments of tables utilizing the base and supports disclosed hereinabove. These figures illustrate the other different types of bases that can be fabricated based on the above disclosure.

[0116] Figure 15 A illustrates a table comprising two supporting legs - each leg comprising one upper table body having 3 arms to support the table surface, a base comprising two arms which have two supports located at the ends. Figure 15B illustrates a similar base as defined in Figure 15A with two supporting posts which are connected to each other by a beam.

[0117] Figures 15C - D illustrate circular and square shaped bases while Figure 15E illustrates a table in which the base is designed.

[0118] In all of these embodiments, the base may be supported using one of the three types of supports described above.

[0119] Variations and modifications may be made to the parts previously described without departing from the spirit or ambit of the disclosure.

[0120] It is to be understood that, if any prior art is referred to herein, such reference does not constitute an admission that the prior art forms a part of the common general knowledge in the art, in Australia or any other country.

[0121] In the claims which follow and in the preceding description of the disclosure, except where the context requires otherwise due to express language or necessary implication, the word “comprise” or variations such as “comprises” or “comprising” is used in an inclusive sense, i.e. to specify the presence of the stated features but not to preclude the presence or addition of further features in various embodiments of the disclosure.
