A puddle flange installation attachment
Field of the Invention
[0001] This invention relates generally to an attachment for an electric grinder, drill or the like which can be used to prepare a recess around a drain aperture in a flooring sheet within which a puddle flange can be subsequently correctly and easily installed.
Background of the Invention
[0002] Floor waste interfacing puddle flange are often installed through fibrous floor panels (such as shower floor panels) to reduce or prevent leakage. A puddle flange comprises a wide annular flange which may be properly sealed against the floor surface such as by using silicon and comprises an integrally formed central drain portion which connects to a floor waste conduit.
[0003] Installation of the puddle flange may comprise manually cutting and shaping a hole in the floor panel to accommodate the central drain.
[0004] Once the puddle flange is installed, a waterproof membrane coat may be applied thereover whereafter tiling be installed.
[0005] The present invention seeks to provide apparatus for the installation of puddle flange which will overcome or substantially ameliorate at least some of the deficiencies of the prior art, or to at least provide an alternative.
[0006] It is to be understood that, if any prior art information is referred to herein, such reference does not constitute an admission that the information forms part of the common general knowledge in the art, in Australia or any other country.
Summary of the Disclosure
[0007] There is provided herein a puddle flange installation attachment for an electric grinder, drill or the like. The attachment comprises a locating cylinder and a grinding disc around the cylinder.
[0008] The grinding disc has a grinding face orthogonal with respect to a rotational axis of the cylinder.
[0009] The attachment is attachable to the electric grinder, drill or the like so that, in use, the locating cylinder can locate within a drain aperture so that the grinding face of the grinding disc can grind a recess around the drain aperture for subsequent installation of a puddle flange therein.
[0010]As such, a puddle flange may be quickly and easily installed using the
attachment.
[0011]The locating cylinder may locate within a preformed drain aperture or
alternatively have a cutting edge to simultaneously itself form the drain aperture.
[0012] The grinding disc may be sized to accommodate commercially available puddle
flange diameters and the grinding face of the grinding disc may form contours
according to specific puddle flange shapes.
[0013]The grinding disc may have apertures therethrough for lightweightness and
escape of dust. The grinding pieces and/or the apertures may be evenly and
symmetrically placed to avoid wobbling. Furthermore, the grinding pieces may
sparsely populate the grinding phase to reduce the requisite torque.
[0014] The grinding pieces may be replaceable and may take the form of block-type
grinding pieces or knife-edged right in pieces in accordance with various
embodiments.
[0015] The grinding disc may have contact pads extending beyond the grinding pieces

Description of Embodiments
[0023] Figure 1 shows as attachment 100 attachable to an electric grinder or the like
for forming a recess around a drainage hole in a floor sheet or surface for the
subsequent installation of a puddle flange therein. The attachment 100 comprises a
locating cylinder 101 and a grinding disc 102 around the cylinder 101.
[0024]The grinding disc 102 has a grinding face orthogonal with respect to a
rotational axis of the cylinder 101.
[0025] The attachment 100 is attachable to the grinder, drill or the like so that, in use,
the locating cylinder can be inserted into a drain aperture so that the grinding face of
the grinding disc 102 can grind a recess around the drain aperture for subsequent
installation of a puddle flange therein.
[0026] Exemplary dimensions are given in Figure 2 wherein the cylinder may comprise
an outer diameter of approximately 150 mm.
[0027] The grinding face may therefore have an inner diameter of approximately 150
mm and an outer diameter of approximately 230 mm. As such, the grinding face may
extend radially out from the cylinder 101 by approximately 40 mm.
[0028] The locating cylinder 101 may be flat edged to be inserted into a preformed
drain aperture. However, in embodiments, the edge of the locating cylinder may be
configured for cutting through a floor surface, such as by having teeth, being diamond
studded or the like to form the drain aperture.
[0029] The grinding face may be defined by a plurality of grinding pieces 103. With
reference to Figure 2, the attachment 100 may comprise a central base plate 111 and
an outer ring 112. The base plate 111 may comprise a central chuck attachment
aperture 107 for the tool. With reference to Figure 5, the baseplate 107 may further
comprise non-central chuck attachment apertures 108 for torsional engagement of
the tool chuck.
[0030] The outer ring 112 may be approximately 10 mm thick.
[0031] The outer ring 112 may define a planar face on which the grinding pieces 103
are located.
[0032] As is evident from Figure 3, the grinding pieces 103 may be evenly spaced
around the cylinder 101.
[0033] The grinding pieces 103 may have radial length. In other words, the grinding
pieces 103 may be longer along the radial axis of the attachment 100 as compared
to with respect to a tangential axis of the attachment 100.
[0034] Furthermore, the grinding pieces 103 may sparsely populate the grinding face.
In other words, the gaps between the grinding pieces 103 are greater than the widths
of the grinding pieces 103.
[0035] With reference to Figure 3, the grinding face may have apertures 105
therethrough. The apertures 105 may have tangential length (i.e. be longer along a
tangential axis as compared to a radial axis) and furthermore may be radially
symmetric. Furthermore, with reference to Figure 5, the central base plate 111 may
itself comprise apertures 106 therethrough.
[0036] In the embodiment shown in Figures 1 - 3, the grinding pieces 103 take the
form of blocks having grinding surfaces whereas, in the embodiment shown in Figures
4 and 5, the grinding pieces 103 are knife-edged.
[0037] The grinding surfaces of the block-type grinding pieces 103 may be planar and
orthogonal with respect to the rotational axis of the cylinder 101. According to the
exemplary dimensions of Figure 2, the block-type grinding pieces 103 may be
approximately 10 mm thick.
[0038] However, in embodiments, the grinding surfaces may be angled at or shaped
to define puddle flange specific contours. For example, the block-type grinding pieces
103 may be angled outwardly or diminish in thickness outwardly.
[0039] Shown in Figure 3, the block-type grinding pieces 103 may stably abut against
the cylinder 101.
[0040] With reference to Figures 4 and 5, the knife-edged grinding pieces 103 may
be supported by a backing 104 with respect to a rotational axis of the attachment 100
(the attachment 100 rotates anticlockwise with reference to the orientation given in
Figure 5) and wherein the backing 104 may extend orthogonally from the surface of
the grinding disc 102.
[0041] The grinding pieces 103 may be replaceable by releasing fasteners 109
through the backing 104.
[0042] Referencing Figure 4, the grinding pieces 103 may be replaceable by releasing
fasteners 109 through the grinding disc 102.
[0043] According to the embodiment shown of Figure 4 and 5, the outer ring 112
extends radially beyond the grinding pieces 103. As such, attachment 100 may grind
the recess until the outer ring 112 contacts the surrounding surface of the floor.
[0044] However, as is shown in Figure 5, the outer ring 112 may further comprise
smooth contact pads 110, such as of felt which contact the surrounding floor surface
without damage. As such, the operator may grind the recess until such time that the
contact pads 110 contact the surrounding floor surface.
[0045] The foregoing description, for purposes of explanation, used specific
nomenclature to provide a thorough understanding of the invention. However, it will
be apparent to one skilled in the art that specific details are not required in order to
