A Mounting Base

Field of the invention

The present invention relates to devices and systems for anchoring a shower door of a shower cabin.

Background of the invention

There are different types of mounting systems and mounting assemblies available for mounting a shower door in a shower cabin. Traditional shower cabins are designed to have an elevated base or sill that is mounted to the floor. The shower door and/or walls of the shower cabin are mounted on the base or sill. As the elevated base or sill extends by a material height from the surface of the surrounding floor, one problem with the base or sill of these traditional shower cabins is that they do not allow barrier-free access to the shower cabin for wheelchairs, and other users may be hindered by or trip over the base or sill when entering the shower cabin.

Sill-less shower cabins are becoming popular in recent years. These shower cabins are more convenient and user-friendly. It is however challenging to install a sill less shower cabin in comparison to a traditional shower cabin with a sill. This is especially the case for frameless and semi-frameless glass panelled shower cabins. For example, some sill-less shower cabins with frameless or semi-frameless glass panels utilise hinges that cantilever the door directly from an adjacent panel. However, such cantilever hinge -0 installations can be expensive, complex to install and may only be able to support doors of a limited width.

There is a need in the art for providing improved mounting systems and assemblies for mounting a shower door in a sill-less shower cabin.

Reference to any prior art in the specification is not an acknowledgement or ?5 suggestion that this prior art forms part of the common general knowledge in any jurisdiction or that this prior art could reasonably be expected to be combined with any other piece of prior art by a skilled person in the art.

Summary of the invention

In accordance with an aspect of the invention, there is provided a mounting base for anchoring a pivoting shower door to a fixture of a sill-less shower cabin, the base including a base body having a door mounting portion and a fixture anchoring portion, wherein: the door mounting portion has upper and lower surfaces and a door mounting formation extending into or from the upper surface for receiving a complementary door pivoting formation, wherein the lower surface is configured to be supported by a floor of the shower cabin; and the fixture anchoring portion has a fixture anchoring formation configured to be anchored to a fixture adjacent the shower door.

O In accordance with a second aspect of the invention there is provided a system for anchoring a pivoting shower door to a fixture of a sill-less shower cabin, the system comprising: a clamping assembly including two substantially parallel walls extending in a substantially vertical direction and a base wall extending in a substantially horizontal direction, the parallel walls and the base wall defining a first channel there between for receiving and clamping a lower edge of the shower door, and a door pivoting formation extending into or from a bottom surface of the base wall; and a mounting base including a base body having at least a door mounting portion and a fixture anchoring portion, wherein: the door mounting portion has upper and lower surfaces and a door mounting formation extending into or from the upper surface for receiving a complementary door pivoting formation, wherein the lower surface is configured to be supported by a floor of the shower cabin; and the fixture anchoring portion has a fixture anchoring formation configured to be anchored to a fixture adjacent the shower door.

Detailed description of the embodiments

Embodiments of the present disclosure provide a mounting base for anchoring a pivoting shower door to a fixture of a sill-less shower cabin. The base includes a base body having a door mounting portion and a fixture anchoring portion. The door mounting portion has upper and lower surfaces, and a door mounting formation extending into or from the upper surface for receiving a complementary door pivoting formation. The lower surface of the door mounting portion is configured to be supported by a floor of the shower cabin. The fixture anchoring portion has a fixture anchoring formation configured to be anchored to a fixture adjacent the shower door.

Referring to Fig. 1, there is shown a perspective view of a mounting base 10 for anchoring a pivoting shower door to a fixture of a sill-less shower cabin. The mounting base 10 has a base body having a door mounting portion 11a and a fixture anchoring portion 11b. The door mounting portion 11a is for anchoring the pivoting shower door and allowing the opening and closing of the pivoting shower door. The fixture anchoring ?5 portion 11b is arranged to be clamped to a fixture adjacent the shower door.

The door mounting portion 11a has an upper surface 13a and a lower surface 13b. In this embodiment, a door mounting formation in the form of cavity 12 is shown as extending into the upper surface 13a towards the lower surface 13b along a pivot axis 12a (shown by a broken line). The cavity 12 is for receiving a complementary pivot pin 72 extending below a lower edge 76 of the shower door 73 (as will be described in greater detail with respect to Fig. 7) such that the shower door is pivotable about the pivot axis 12a. In embodiments in which the shower door is formed from a glass panel, such an arrangement may be avoid the necessity of forming a cut out in the shower door. In an alternative embodiment, the mounting base may have a pivot pin extending outwardly from the upper surface 13a of the door mounting portion 11a, that can be received in a cavity extending into the lower edge of the shower door.

The lower surface 13b of the door mounting portion 11a is arranged to be directly supported by the floor 15. Accordingly, the shower door may be supported on the floor of the shower cabin by the mounting base rather than being cantilevered off an adjacent panel. Such an arrangement may allow the shower door to have a greater width.

A waterproof adhesive, such as silicone, may be used to secure the mounting base to the floor of the shower cabin. For example, a bead of the waterproof adhesive may be applied to either the floor or the lower surface 13b of the door mounting portion 11a before the mounting base is arranged on the floor. In this embodiment, the fixture anchoring portion 11b has a lower surface 13c that is coplanar with the lower surface 13b of the door mounting portion 11a. This allows lower surfaces 13b, 13c of the door mounting and fixture anchoring portions to simultaneously contact the floor 15. Accordingly, the bead of the waterproof adhesive may be applied to both the lower surface 13b of the door mounting portion 11a and the lower surface 13c of the fixture anchoring portion 11b.

O The fixture anchoring portion 11b has a fixture anchoring formation configured to be anchored to the fixture adjacent the shower door. In an embodiment, the fixture may be a glass panel, a panel of another material such as plastic, a metal extrusion, or a concrete wall held adjacent the shower door.

In this embodiment, the fixture anchoring formation includes a pair of substantially ?5 parallel flanges 14a and 14b which extend from a web 18. The parallel flanges 14a, 14b extend in a substantially vertical direction from the substantially horizontally extending web 18. The flanges 14a, 14b and the web 18 define a channel 14c therebetween for receiving the fixture. The fixture is shown as a glass panel 74, for example, in Figs. 7 and 8, which is received within the channel 14c formed between the flanges 14a and 14b and web 18.

Alternative embodiments may use a different structure of the fixture anchoring formation which allows the fixture anchoring portion 11b to be clamped to different types of fixtures such as a vertical panel, a metal extrusion or a concrete wall adjacent the shower door. For example, the fixture anchoring portion may include a single flange extending in a substantially vertical direction from an end of the door mounting portion. The flange can have at least one through hole for receiving bolts or screws such that the flange can be fixed to a fixture adjacent the shower door, e.g. a substantially vertical frame such as an aluminium extrusion.

As shown in Fig. 1, the lower surface of the web 18 forms the lower surface 13c of the fixture anchoring portion 11b. Accordingly, the fixture also may be supported on the floor by the mounting base. Furthermore, the upper surface 13d of the web 18 is lower than the upper surface 13a of the door mounting portion 11a.

In this embodiment, the cavity 12 is cylindrically shaped having a circular cross section. In this embodiment, the cavity 12 is an aperture or through hole that extends all the way down to the lower surface 13b of the door mounting portion 11a (for example, as evident in Figs. 1, 3, 6 and 7). In an alternative embodiment, the cavity 12 may be a blind hole that extends only to a certain depth within the door mounting portion 11a and does not extend all the way down to the lower surface 13b.

In this embodiment, the pivot pin has a cross section that corresponds to the cross section of the cavity such that the pivot pin is receivable within the cavity 12. As shown in Fig. 7, the pivot pin 72 is received inside the cavity 12 of the door mounting portion 11a. O In this embodiment, the pivot pin 72 is part of a clamping assembly 71 which is clamped to a lower edge 76 of the shower door 73 (details of the clamping assembly 71 are described later with reference to Figs. 7 and 9-10). In an alternative embodiment, the pivot pin may extend directly from the lower edge 76 of the shower door 73. For example, the pivot pin may be an integral part of the shower door 73. Alternatively, the pivot pin ?5 may be directly fixed or glued to the lower edge 76 of the shower door 73. In a further alternative embodiment, the pivot pin may extend from the lower edge 76 of the shower door 73 using a system other than the clamping assembly 71.

Referring to Figs. 2 and 3, there are shown a side view and a sectional side view, respectively, of the mounting base 10. In this embodiment, the door mounting portion 11a has a length of 31 mm and the fixture anchoring portion 11b has a length of 40 mm such that the mounting base 10 has an overall length of 71 mm. It will be appreciated that, in alternative embodiments, the length of each of the portions and the mounting base as a whole may differ depending on the mounting requirements of a particular shower cabin. For example, the length of the door mounting portion 11a may be in the range of 20-40 mm, preferably 25-35 mm, the length of the fixture anchoring portion 11b may be in the range of 30-50 mm, preferably 35-45 mm, such that the overall length of the mounting base 10 may be in the range of 50-90 mm, preferably 65-75 mm.

In this embodiment, the door mounting portion 11a has a height of 10 mm. It will be appreciated that, in alternative embodiments, the height of the door mounting portion may differ, e.g. it may be in the range of 8-12 mm.

In this embodiment, the cavity 12 has an inner diameter of 8 mm and the pivot axis 12a is offset 6 mm from an end surface 13f of the door mounting portion 11a opposite the fixture anchoring portion 11b. This combination of offset and inner diameter leaves the door mounting portion with a minimum wall thickness of 2 mm between an inner surface of the cavity 12 and the end surface 13f. It will be appreciated that a minimum wall thickness substantially less than 2 mm may not provide the door mounting portion 11a with sufficient structural integrity. It also will be appreciated that a minimum wall thickness substantially greater than 2 mm may unnecessarily encroach into the shower cabin entry, thereby reducing the advantages of the sill-less aspect.

In combination with the door mounting portion 11a having a length of 31 mm, this 6 mm offset may also allow for the pivot axis 12a to align with the pivot axis of a standard head fitting that may be provided at the head of the shower cabin entry. It will be appreciated that, in alternative embodiments, the inner diameter of the cavity and the offset of the pivot axis from the end surface 13f of the door mounting portion 11a may differ depending on the offset of the pivot axis of a corresponding head fitting, the size of the pivot pin to be accommodated, e.g. the inner diameter may be in the range of 5-10 ?5 mm, and the offset may be in the range of 5-7 mm.

In this embodiment, the parallel flanges 14a and 14b of the fixture anchoring portion 11b have an overall height of 25 mm. It will be appreciated that, in alternative embodiments, the height of the fixture anchoring portion may differ depending on the mounting requirements of a particular shower cabin, e.g. it may be in the range of 20-30 mm.

In this embodiment, each of the threaded through holes 31a and 31b has a thread size of M8. In this embodiment, the threaded through holes 31a and 31b are formed with their axial centres at a height of 15 mm from the lower surface 13c of the fixture anchoring portion 11b (i.e. distance between the centre of the through hole and the lower surface 13c). It will be appreciated that this height may differ in alternative embodiments and may be in the range of 13-18 mm.

In this embodiment, the distance between the center of the threaded hole (31a or 31b) and the side 13e of the fixture anchoring portion 11b is 20 mm. It will be appreciated that this distance may differ in alternative embodiments and may be in the range of 18 22 mm.

As shown in Figs. 2 and 3, the parallel flanges 14a and 14b have rounded corners 34a and 34b each having a corner radius of 7.5 mm. In alternative embodiments, these rounded corners may have different corner radii which may be in the range of 5-10 mm. In further alternative embodiments, the parallel flanges 14a and 14b may be formed with chamfered corners or right angled corners, or have a different shape in elevation to the substantially oblong shape depicted in Figs. 2 and 3, e.g. semi-circular, triangular, trapezoidal, etc.

Figs. 4, 5 and 6 provide a top view, a sectional end view and a bottom view, respectively, of the mounting base 10.

As shown in Fig. 4, the cavity 12 and the channel 14c are colinear. This allows the shower door 73 to be substantially in line with the adjacent panel 74. In an alternative embodiment, the cavity 12 and the channel 14c may not be colinear; this will allow the shower door 73 to be mounted at an angle an adjacent fixture.

As shown in Figs. 4-6, the door mounting portion 11a and fixture anchoring portion 11b have contiguous front surfaces 17a and 17b, and contiguous back surfaces 18a and 18b. In this embodiment, the door mounting portion 11a and the fixture anchoring portion ?5 11b have the same width of 17 mm. It will be appreciated that the width of the door mounting portion may differ from the width of the fixture anchoring portion in alternative embodiments, e.g. each width may be in the range of 15-20 mm.

In this embodiment, the parallel flanges 14a, 14b have widths of 5 mm. It will be appreciated that, in alternative embodiments, the width of flanges 14a, 14b may differ, e.g. it may be in the range of in the range of 4-6 mm. The parallel flanges 14a and 14b are spaced apart by the channel 14c having a width of 7 mm. The channel is wide enough to receive the glass panel 74 of thickness 6 mm. It will be appreciated that the channel width may differ in alternative embodiments which may be in the range of 6-8 mm.

As shown in Fig. 5, the web 18 has a height of 2.5 mm. It will be appreciated that the web may have different height in alternative embodiments e.g. the web may have a height in the range of 2.0 mm to 3.0 mm. As shown in Fig. 8A packer 81 of height 0.75 mm may be placed on the upper surface 13d of the web 18 to prevent any damage to the base of the glass panel 74. In alternative embodiments, the packer may have a different thickness, e.g. a height in the range of 0.5-1.0 mm. In this embodiment, the combination of the web 18 having a 2.5 mm height and the packer 81 having a height of 0.75 mm ensures that the bottom edge of the glass panel 74 is as close to the floor as possible, whilst stilling being at least 3 mm (3.25 mm in this case) above the floor.

The door mounting portion has rounded corners 41a and 41b formed at the intersection of the front surface 17a and end surfacel3f, and the back surface 18a and the end surface 13f, respectively. The rounded corners 41a and 41b have a corner radius of 2 mm each. It will be appreciated that the corner radii of the rounded corners may differ in alternative embodiments which may be in the range of 1-3 mm. It will be also appreciated that, in further alternative embodiments, the door mounting portion may be formed with chamfered corners or right angled corners, or have a different shape in plan view to the substantially oblong shape depicted in Figs. 4 and 6, e.g. semi-circular, triangular, trapezoidal, etc.

Fig. 6 shows a bottom view of the mounting base 10 having contiguous bottom surfaces 13b and 13cof the doormounting portion 11a and fixture anchoring portionl1b, respectively.

Fig. 7 shows a system 70 for mounting a shower door 73 to a floor 75 of a sill-less ?5 shower cabin. The system 70 includes the clamping assembly 71 and the mounting base 10, both designed to operate together for mounting the shower door 73 to the floor 75.

In an embodiment, the fixture 74 may be provided substantially colinearly with or at an angle to the shower door in the closed position. For example, in Fig. 7, the fixture is a glass panel 74 held substantially colinearly with the closed shower door 73.

As shown in a front perspective view of the clamping assembly 71 in Fig. 9, the clamping assembly 71 has two parallel walls 91a and 91b extending in a vertical direction.

One parallel wall 91a is connected to a horizontally extending base wall 91c at its lower end. The parallel walls 91a and 91b together with the base wall 91c form a channel 91d therebetween. The channel91d is configured to receive the shower door 73 from its lower edge 76 that can rest on an upper surface 92a of the base wall 91c. In this embodiment, the shower door is a glass panel of width (6.0 mm) smaller than the width (7.0 mm) of the channel 91d. A clamping mechanism may be used to clamp the shower door 73 in place between the parallel walls 91a and 91b of the clamping assembly 71. The clamping mechanism may comprise a boss (not shown) provided with an outer nylon bush, having an internal thread and extending from the inner surface of parallel wall 91a towards parallel wall 91b, and a corresponding aperture 93 formed in parallel wall 91b. The boss (and its outer nylon bush) may be inserted through an aperture formed in the glass panel of the shower door 73, and a screw (not shown) may be inserted through the aperture 93 and screwed into the internal thread of the boss to clamp the shower door 73 in place. In this embodiment, the aperture 93 has a countersink on an exterior surface of the wall 91b, and the screw may be a stainless steel countersunk screw. Padding layers, such as neoprene gaskets, may be provided between the glass panel of the shower door and parallel wall 91a and/or between the glass panel of the shower door and parallel wall 91b. The padding layers and/or the nylon bush may protect the glass door from direct contact with the metal of the clamping mechanism.

As shown in Fig. 7, the base wall 91c has a lower surface 92b from where the pivot pin 72 extends. This pivot pin 72 is fitted with a nylon bush (not shown) and is received within the cavity 12 of the mounting base 10. The nylon bush may prevent metal on metal contact between the pin 72 and the inner surfaces of the cavity 12 of the mounting base 10. It may also have an axial dimension that ensures that the lower surface 92b of the ?5 base wall 91c is distanced from the upper surface 13a of the door mounting portion. In one example, this distancing may result in the lower edge 76 of the glass panel 73 having a height of approximately 14 mm above the floor of the shower cabin.

The fixture anchoring portion 11b receives the glass panel 74 between the parallel flanges 14a and 14b. The grub screws 32a and 32b are used to align the glass panel within the parallel flanges 14a and 14b of the mounting base 10. The pivot pin 72 can rotate within the cavity 12 thereby allowing the shower door 73 to pivot about the pivot axis 12a. A small gap 76 is provided between the shower door 73 and the glass panel 74 to avoid any damage to the shower door 73 and/or glass panel 74 during the opening or closing of the shower door 73. In an embodiment, the gap 76 has a dimension of at least 3 mm. In this embodiment, both the shower door and the glass panel have a thickness of approximately 6 mm in line with the minimum thickness requirements for Grade A toughened glass in frameless and semi-frameless installations according to AS/NZS 1288.

In this embodiment, each of the parallel flanges 14a, 14b defines a threaded through hole for receiving a grub screw. The grub screws 32a, 32b are received in the threaded through holes 31a, 31b of the parallel flanges 14a and 14b, respectively. Each of the grub screws 32a, 32b has a nylon tip (33a, 33b) so that the glass panel 74 is not damaged when the grub screws 32a, 32b are screwed in for aligning the glass panel 74 between the parallel flanges 14a and 14b. The grub screws 32a and 32b are made of stainless steel. In an embodiment, each of the grub screws 32a and 32b may have a length (inclusive of the length of the nylon tip) that is equal to or slightly less than the width of the parallel flanges 14a and 14b. In this embodiment, the length of the grub screw (inclusive of the length of the nylon tip) is the same as the width of the parallel flanges 14a and 14b. This allows the grub screws 32a and 32b to be received within the through holes 31a and 31b, respectively, without protruding from the front and back surfaces 17b and 18b of the fixture anchoring portion 11b. In an alternative embodiment, alignment may be achieved with other means, such as the use of shims or packers alone or in combination with a single grub screw 32a (or 32b).

In one embodiment, the door mounting portion 11a and fixture anchoring portion 11b are cast as separate brass pieces and then welded together to form a single body of the mounting base 10. This process of casting in brass and then welding the two cast pieces together at a flat interface combines the cost effectiveness of casting with a ?5 configuration that achieves the required shape complexity. The weld join may be polished to ensure the lower and side surfaces are smooth faced. It also will be appreciated that, in other embodiments, the door mounting portion 11a and fixture anchoring portion 11b may be integrally formed and/or formed from materials other than or in addition to cast brass, e.g. stainless steel, brass with chrome plating.

By way of clarification and for avoidance of doubt, as used herein and except where the context requires otherwise, the term "comprise" and variations of the term, such as "comprising", "comprises" and "comprised", are not intended to exclude further additions, components, integers or steps.

It will be understood that the embodiments disclosed and defined in this specification extends to all alternative combinations of two or more of the individual features mentioned or evident from the text or drawings. All of these different combinations constitute various alternative aspects of the embodiments.
