BACKGROUND
[0002] Typically, a columbarium is constructed in the form of an indoor or
outdoor wall of a
building or some other large free-standing structure in a cemetery. As
cremation is becoming
increasingly more common, cemeteries are adding more columbarium structures,
and many
churches and even some universities are now placing columbarium structures on
their grounds.
With this growth of columbaria construction, cemeteries, churches and
universities are seeking
more uniquely configurations of columbarium structures, rather than the more
traditional wall-
type columbarium.
[0003] It is generally desired to have the stone facing stones or facing
stones which cover the
columbarium niche to be secured by mounting hardware which is concealed or
hidden from view
so as not to detract from the appearance of the stone and the reverent
atmosphere of the
columbarium. The concealed mounting hardware must resist corrosion and it must
securely hold
the facing stones in position despite extreme temperature swings and countless
freeze-thaw
cycles for season-after-season and year-after-year, for decades, if not
centuries. In addition, the
mounting hardware must permit the facing stones to be relatively easily
removed and replaced
even after years or decades of being exposed to the elements.
[0004] With the desire for more unique configurations of columbarium
structures, there is a
need in the industry for a concealed mounting system which is capable of being
used with
virtually any size or shape of facing stone, which has few pieces, is
relatively quick and easy to
assemble and install in order to reduce material costs and labor costs, and
which permits
1

WO 2014/031168 PCT/US2013/032146
adjustment of the facing stones to maintain uniformity in spacing between the
stones, or to
account for inconsistencies in stone thickness, or, if desired, to provide
relief patterns in the
facings stones, by recessing some stones with respect to other stones.

DESCRIPTION
[0021] Referring now to the drawings, wherein like reference numerals
designate identical or
corresponding parts throughout the several views, FIG. 1 is a perspective view
of a columbarium
structure 10 in the form of an obelisk. The obelisk structure 10 has a front
side 12, a rear side 14,
a left side 16, a right side 18. Each of the front, rear, left and right sides
are angled inwardly
from their respective lower ends toward their upper ends, such that the upper
end of the obelisk
has a periphery that is less than the periphery of the lower end of the
obelisk. In the
embodiment of FIG. 1, the obelisk structure 10 is shown having a pyramidal
shaped capstone 20
and a stepped base 22. It should be appreciated, however, that the obelisk 10
may have any
desired configuration of a capstone 20 or any desired base 22. Alternatively,
the obelisk 10 may
be placed directly on a concrete slab or floor or other structure, where a
base is not desired.
[0022] The front and rear sides 12, 14 of the obelisk 10 includes a
plurality of niche facing
stones 24 which are removable for accessing the niches 26 in which cinerary
urns or urn boxes
28 (FIG. 5) may be placed. Because each of the sides of the obelisk structure
10 are angled
3
CA 02882729 2015-02-20
WO 2014/031168 PCT/US2013/032146
inwardly, the niche facing stones 24 are trapezoidal in shape. The left and
right sides 16, 18 are
enclosed by left and right side panels 30, 32. In the embodiment of FIG. 1,
the left and right side
panels 30, 32 are shown as being comprised of a single panel. However,
depending on the size
of the obelisk structure, the side panels 30, 32 may be constructed of
multiple panels. The facing
stones 24, side panels 30, 32, capstone 20 and base 22, may be made of any
desired material, but
typically would be made of stone, such as honed or polished granite or marble,
for example.
FIG. 2 is a front side elevation of the obelisk structure 10 of FIG. 1. The
rear side elevation is
the same as the front side elevation view. FIG. 3 is a left side elevation
view of the obelisk
structure 10 of FIG. 1. The right side elevation view is the same as left side
elevation view.
FIG. 4 is atop plan view of the obelisk structure 10 of FIG. 1.
[0023] It should be appreciated that the obelisk structure 10 may vary in
height, length and
width as desired for aesthetic reasons and for accommodating different numbers
or sizes of urns
28. Various configurations of obelisk columbarium structures are shown in
Applicant's co-
pending design patent application no. 29/449,155 filed March 14, 2013 which is
incorporated
herein in its entirety by reference. FIG. 5 shows the obelisk 10 of FIG. 1
with the niche facing
stones 24 removed to better illustrate the arrangement of the urns 28 within
the obelisk. In this
embodiment, the obelisk is shown as having eight rows of niches 26 on both its
front and rear
sides 12, 14 which can accommodate a total of 38 urn boxes 28 having typical
length, width and
height dimensions of 5.5 x 5.5 x 7 inches. FIG. 6 is the same front or rear
elevation view of the
obelisk columbarium structure as in FIG. 2, illustrating the arrangement of
the cinerary urns
within the obelisk. FIG. 7 is the same left or right side elevation view of
the obelisk
columbarium structure as in FIG. 3, showing the arrangement of the cinerary
urns within the
obelisk and showing an embodiment of the concealed mounting system for the
facing stones
(discussed later).
[0024] As best viewed in FIGs. 8 and 9, which are enlarged partial cross-
sectional views
along lines 8-8 and 9-9 of FIG. 5, respectively, the obelisk structure 10
includes an internal
framework 40 of vertically spaced, horizontal shelves 42 and opposing vertical
backwalls 44, 46
which define the individual niches 26 accessible from the front and rear sides
of the obelisk
structure upon removal of the facing stones 24. The horizontal shelves 42 are
supported by L-
shaped brackets 48, such as extruded or rolled angles. One leg of the L-shaped
brackets are
4
CA 02882729 2015-02-20
WO 2014/031168 PCT/US2013/032146
secured to the opposing inner faces of the end panels 30, 32 by threaded
connectors or anchors
retained by a nut. The inward projecting leg of the L-shaped bracket serves as
a support for the
ends of the horizontal shelves 42. The brackets 48 are positioned so that the
shelves 42 align
with the top and bottom of the facing stones 24 of the respective niches 26.
In the embodiment
shown, the horizontal shelves 42 and the backwalls 44, 46 are constructed of
cement board, but
other suitably rigid, durable and weather resistant material may also be used
including, for
example, fiber reinforced polymer, aluminum, stainless steel and plastic.
[0025] To provide lateral rigidity to the backwalls 44, 46 vertically
spaced lateral supports
50, such as extruded or roll formed channels may be attached to the backwalls
by threaded
connectors or rivets. Because the horizontal shelves are primarily supported
only at their ends by
the inwardly projecting leg of the L-shaped brackets 48, it should be
appreciated that depending
on the horizontal span between the end panels, the inner side of the
horizontal shelves (i.e. the
end nearest the backwall) may be need to be supported to prevent to shelves
from bowing
downwardly over time or due to the weight of the urns. Accordingly, the
lateral supports 50 may
include outwardly projecting flanges 52 to frictionally receive an inner side
of the horizontal
shelves 42. If the horizontal span of the shelves is short, it may be
unnecessary to support the
inner side of every shelf and therefore the lateral supports may be vertically
spaced every other
shelf or more depending on the height of the obelisk and the horizontal span
of the shelves.
[0026] The outer side of the horizontal shelves 42 (i.e., the side nearest
the facing stones)
supports a front rail 60 which cooperates with a concealed mounting system 100
(described later)
to adjustably support the facing stones 24. In one embodiment the front rail
60 is fabricated from
extruded aluminum, but may be fabricated from any other suitably rigid,
weather resistant, and
dimensionally stable, extrudable or pultrudable materials such as fiber
reinforced polymer,
stainless steel and plastic. As best shown in FIGs. 10-13, the front rail 60
may have an inwardly
projecting flange 62 which may be attached to the horizontal shelf 42 by
rivets or threaded
connectors. Alternatively, the front rail 60 may include inwardly projecting
flanges for
frictionally receiving the outer side of the horizontal shelves 42 as
disclosed in Applicant's U.S.
Patent No. 8,122,650, incorporated herein in its entirety by reference. In yet
another alternative
embodiment, the front rail 60 and horizontal shelf 42 may be integrally formed
as an extrusion
creating a single horizontal member as disclosed in Applicant's co-pending
application
CA 02882729 2015-02-20
WO 2014/031168 PCT/US2013/032146
13/375,803 (publication no. US2012/0167488), incorporated herein in its
entirety by reference.
In yet another alternative embodiment, the front rail 60 may be fabricated
from an extrusion and
attached to a shelf fabricated from bent plate or, alternatively, the front
rail 60 may be fabricated
from angle stock or bent plate or the front rail 60 may be roll formed, all of
which embodiments
are disclosed in Applicant's co-pending application no. 13/589,807 filed
August 20, 2012,
incorporated herein in its entirety by reference.
[0027] In each of the above embodiments, the front rail 60 includes an
outwardly projecting
flange 64 and a downwardly projecting flange 66. A top channel 68 and a top
slot 70 are formed
along the length of the forwardly projecting flange 64. Referring to FIGs. 8-
10, the top slot 70 of
the lower niche and the downwardly projecting flange 66 of the upper niche
cooperate to receive
and retain an inner closure panel 72. A turn tab 74 is pivotally secured to
the downwardly
projecting flange by a threaded connector or rivet 76 to hold the top end of
the inner closure
panel 72 in position, while the bottom end of the inner closure panel 72 is
received in the top slot
70. To remove the inner closure panel 72, the turn tab 74 is rotated up to
free the top end of the
inner closure panel, allowing the top end to be tilted outwardly so it can be
grasped and lifted
from the top slot 70 of the lower front rail 60.
[0028] Referring to FIGs. 8-14, one embodiment of the concealed mounting
system 100
includes an upper clip 102 and at least one, preferably two, lower support
hangers 104 secured to
the back side of the facing stone 24. The upper clip 102 includes an upwardly
curving hook 106
that receives and is engaged by the upper lock 150 (described in greater
detail later). The lower
support hangers 104 comprise an L-shaped bracket 108 with threaded studs 110
threadably
received through threaded apertures 112 in the rearwardly projecting leg 114
of the L-shaped
bracket 108. The upper clip 102 and hangers 104 may be fabricated from
extruded aluminum or
other suitably rigid, weather resistant and dimensionally stable, extrudable
or pultrudable
material.
[0029] In the embodiment as best illustrated in FIGs. 11-14, the clip 102
and hangers 104 are
secured with threaded anchors 120. The heads 122 of the threaded anchors are
received within
inverted T-shaped slots 124 cut into the back side of the facing stone 24 such
as disclosed in US
Patent No. 4,020,610, which is incorporated herein in its entirety by
reference. The threaded
6
CA 02882729 2015-02-20
WO 2014/031168 PCT/US2013/032146
shaft 126 of the anchors 120 project from the back face of the facing stone 24
and are received
through apertures 128 in the clips 102 and hangers 104. A nut 130 is threaded
onto the
projecting threaded shaft 126 and is tightened to securely attach the clips
102 and hangers 104 in
place and to prevent their rotation.
[0030] One embodiment of the concealed mounting system 100 includes at
least one hanger
support 132, preferably two, for cooperatively receiving and supporting the
threaded stud 110.
The hanger support 132 comprises a swivel socket with an elongated body 134
having an
aperture 136 near one end and a socket or indentation 138 at an opposite end.
The swivel socket
132 is slidably positioned along the front rail 60 by a threaded lug 140
having a head 142
received within the top channel 68 of the front rail 60. The shaft 144 of the
lug 140 extends
through the top channel 68 and into the aperture 146 of the swivel socket 132
and is secured by a
nut 148. By loosening and tightening the nut 148, the swivel socket 132 can
pivot or swivel
about the lug 140 and can be slidably, adjustably, fixably positioned anywhere
along the length
of the top channel 68 in order to align the socket 138 to receive the
downwardly extending
threaded stud 110. By turning the threaded stud 110 clockwise or
counterclockwise it will cause
the facing stone 24 to raise or lower, respectively, relative to the swivel
socket 132 and front rail
60 thereby providing vertical adjustment of the facing stone 24. Likewise, by
loosening and
tightening the nut 148 on the lug 140, the swivel socket 132 can pivot
inwardly or outwardly
relative to the front rail 60 thereby providing in-and-out or fore-and-aft
adjustment at the bottom
of the facing stone 24.
[0031] One embodiment of the concealed mounting system 100 also includes an
upper lock
150. The upper lock 150 includes a rearwardly projecting flange 152 having an
elongated slot
154. Similar to the swivel sockets 132, the upper lock 150 is slidably
positioned along the front
rail 60 by a threaded lug 156 having a head 158 received within the top
channel 68 of the front
rail 60. The shaft 144 of the lug 140 extends through the top channel 68 and
into the elongated
slot 154 of the rearwardly projecting flange 152. By loosening and tightening
the nut 148
threaded over the shaft 144 of the lug 140, the upper lock 150 can be
positioned inwardly or
outwardly relative to the front rail 60 thereby providing in-and-out or fore-
and-aft adjustment at
the top of the facing stone 24. Furthermore, by loosening and tightening the
nut 148 on the lug
140 the upper lock 150 can be slidably, adjustably, fixably positioned at the
desired location
7
CA 02882729 2015-02-20
WO 2014/031168 PCT/US2013/032146
along the top channel 68.
[0032] One embodiment of the upper lock 150 includes a forwardly extending
channel 156,
and a downwardly extending channel 158. Apertures 160, 162 extend through the
forwardly
extending channel 156 and downwardly extending channel 158, respectively. A
locking screw
164 passes through both apertures 160, 162. The locking screw 164 includes a
threaded upper
shaft 166 and a rectangular lower shaft 168. The threaded upper shaft 166 is
threadably received
by a nut 170 disposed within the forwardly extending channel 156. The nut 170
is larger than
the diameter of the apertures 160, 162 such that the locking screw 164 is
vertically supported
within the forwardly extending channel 156 by the nut 170. The width of the
rectangular lower
shaft 168 of the locking screw is preferably only slightly less than the width
between the legs of
the downwardly extending channel 158 such that the rectangular lower shaft 168
prevents the
locking screw 164 from rotating within the channel 158.
[0033] As best illustrated in FIG. 10, the nut 170 is accessible for
rotation by an open end
wrench 172 (FIG. 10) inserted in the gap 174 between vertically adjacent
facing stones 24. It
should be appreciated that because the cooperation of the rectangular lower
shaft 168 within the
downwardly extending channel 158 prevents the locking screw 164 from rotating,
upon turning
the nut 170 clockwise using the wrench 172, the locking screw 164 is caused to
move
downwardly allowing the end of the rectangular lower shaft 168 to engage the
upwardly curving
hook 106 of the upper clip 102. Likewise, by rotating the nut 170 counter-
clockwise using the
wrench 172, the locking screw 164 is caused to move upwardly thereby
disengaging the end of
the rectangular lower shaft 168 from the upward hook 106 of the clip 102 and
allowing the
facing stone 24 to be easily removed for access to the niche 26. The end of
the rectangular lower
shaft 168 is preferably beveled to better mate with the upwardly curving hook
106.
[0034] The in-and-out adjustment capability at the top of the facing stone
24 when combined
with the in-and-out adjustment capability at the bottom of the facing stone
24, allows for easier
and faster installation of facing stones and better accommodates different
facing stone
thicknesses, whether due to thickness tolerances or inconsistencies in the
stone or whether
different stone thicknesses are being used to create a relief pattern in the
face of the obelisk.
Furthermore, it should be appreciated that once the nut 148 is tightened down,
the swivel sockets
8
CA 02882729 2015-02-20
WO 2014/031168 PCT/US2013/032146
132 and the upper lock 150 are prevented from pivoting or sliding horizontally
within the top
channel 68. Thus, if the facing stone 24 is ever removed, when it comes time
to replace the
facing stone, the threaded studs 110 will be guided to seat in the bottom of
the sockets 138 of the
swivel socket 132 and the upper lock 150 will cooperate to ensure that the
facing stone is
returned to the exact same position before it was removed,thereby avoiding the
tedious task of
having to readjust the facing stone to ensure a uniform gap with the adjacent
facing stones.
[0035] As shown in FIG. 10, it should also be appreciated that through the
pivotable
movement of the swivel sockets 132, and with the centrally positioned upper
lock 150, the facing
stone is capable of pivoting about a vertical Y axis as indicated by arrow
180. Furthermore, with
threaded studs 110 received within the swivel sockets 132, and with the
curvature of the upper
clip cooperating with the upper lock 150, the facing stone is also able to
pivot about a horizontal
X axis as indicated by arrow 182. Also, with the independent vertical
adjustability of the
threaded studs 110 cooperating with the swivel sockets, the facing stone is
also able to pivot
about the Z axis as indicated by arrow 184. Thus, the facing stone 24 is
capable of being
adjustable in three dimensions or about three axes of rotation, thereby
enabling infinite
adjustment of the facing stones 24 to ensure uniform gaps are maintained
between adjacent
facing stones for a more pleasing aesthetic appearance and to ensure the front
of adjacent facing
stones are flush if desired, or as illustrated in FIG. 8, to allow adjacent
facing stones to be moved
in or out to create a relief pattern if desired.
[0036] As shown in FIG. 8, it should also be appreciated that the concealed
mounting system
100 allows more versatility than current facing stone mounting systems by
allowing the upper
clips 102 and hangers 104 on the back of the facing stones 24 to have varying
positions between
adjacent facing stones and it allows for the facing stones 24 to be placed
anywhere along the
front rail 60. This versatility permits different sized facing stones to be
used in the event it is
desired to have multiple or different sized facing stones over the obelisk
niches 26.
[0037] The foregoing hardware and components comprising the concealed
mounting system
100 are preferably made of corrosion resistant material such as stainless
steel, brass or aluminum
or are plated or treated with a corrosion resistant finish. Alternatively the
hardware and
components may be produced using a sintering process. The components are also
preferably
9
CA 02882729 2015-02-20
WO 2014/031168 PCT/US2013/032146
galvanically compatible with the other components to which they come into
contact to minimize
oxidation or corrosion so they remain capable of supporting the loads
anticipated for the
structure and so they can withstand the extreme environmental conditions to
which they may be
subject.
[0038] FIGs. 15 and 16 illustrate an alternative embodiment of an obelisk
structure 10'. As
in the previously described embodiment, the obelisk structure 10' has a front
side 12, a rear side
14, a left side 16, a right side 18. In the embodiment of FIG. 15, the obelisk
structure 10 is
shown having a pyramidal shaped capstone 20 and a stepped base 22. As with the
previously
described embodiment, it should be appreciated, however, that the obelisk 10'
may have any
desired configuration of a capstone 20 or any desired base 22. Alternatively,
the obelisk 10' may
be placed directly on a concrete slab or floor or other structure, where a
base is not desired.
[0039] As in the previous embodiment, the front and rear sides 12, 14 of
the obelisk 10'
includes a plurality of niche facing stones 24 which are removable for
accessing the niches 26 in
which cinerary urns or urn boxes 28 may be placed. The left and right sides
16, 18 are enclosed
by left and right side panels 30, 32. In the embodiment of FIG. 15, the left
and right side panels
30, 32 are shown as being comprised of a single panel. However, depending on
the size of the
obelisk structure, the side panels 30, 32 may be constructed of multiple
panels. The facing
stones 24, side panels 30, 32, capstone 20 and base 22, may be made of any
desired material, but
typically would be made of stone, such as honed or polished granite or marble,
for example.
[0040] As with the previous embodiment, it should also be appreciated that
the obelisk
structure 10' may vary in height, length and width as desired for aesthetic
reasons and for
accommodating different numbers or sizes of urns 28. Various configurations of
obelisk
columbarium structures are shown in Applicant's co-pending design patent
application no.
29/449,155 filed March 14, 2013 previously incorporated herein in its entirety
by reference.
[0041] Unlike the previously described embodiment of the obelisk structure
10, the
horizontal shelves 42 of the alternative embodiment of the obelisk 10' project
outwardly and are
substantially flush with the edges of the end panels 30, 32. Thus, in this
embodiment, the
horizontal shelves 42 are preferably fabricated from the same stone or a
complimentary stone or
material as the facing stones 24 and end panels 30, 32 and are honed or
polished to the same or a
CA 02882729 2015-02-20
WO 2014/031168 PCT/US2013/032146
complimentary finish. Also, unlike the previous embodiment, the facing stones
24 may be
recessed inwardly from the edges of the horizontal shelves 24 and the edges of
the end panels 30,
32. In one embodiment, the facing stones 24 may be received in a groove 25
formed in the upper
surface of the shelf 42 to receive the lower end of the facing stone 24. The
upper end of the
facing stone 24 may be secured using a soffit lock 200 as disclosed in
Applicant's U.S. patent no.
5,802,781 ("the '781 patent"), incorporated herein in its entirety by
reference, but rather than the
socket locks 200 being secured to the stones 24 as shown the '781 patent, the
soffit locks 200
may be secured to the back sides of the stones 24 using the T-shaped slots 124
