DETAILED PTION
Unless the context y requires otherwise, throughout the description and
the claims, the words “comprise”, “comprising”, and the like are to be
construed in an inclusive sense as opposed to an exclusive or exhaustive
sense; that is to say, in the sense of "including, but not limited to".
According to illustrative embodiments, glass wool insulation is utilized to
replace all or part of conventional two part rigid polyurethane foam spa
[followed by page 3]
insulation. The glass wool may be, for example, the JM Spider in
fiberglass insulation product available from John Manville, Denver, Colorado.
Antistatic silicone may be added to the John Manville formula in order to
ate static and prevent the glass wool from wicking up moisture.
in a first illustrative embodiment, a spa is positioned with its bottom end 13 up,
for example, as shown in Figs. 1-3. A cloth or other cover may be placed over
the bottom 13 of the spa 11 and fixed in position, for example, across the
parallel wooden bottom rails 15. A glass wool spraying tube 17 (Fig. 2) may
be then inserted through the cloth and the glass wool 16 blown into the spa
interior through the tube 17. In a production embodiment, a reusable fixture
may be constructed and used to cover the spa bottom 13 during the process
of blowing the glass wool 16 into the spa interior. Fig. 1 illustrates the spa 11
after insulation has been blown into several of the interior regions or cavities
beneath the parallel horizontal bottom frame members or rails 15. An
advantage over rigid ethane foam is that the glass wool 16 may be
removed in the field to tate repair and then replaced. Fig, 3 illustrates an
area 21 where glass wool 16 has been removed to expose interior spa water
piping 23.
According to a second illustrative embodiment illustrated in Figs 4-14, a spa
111 ready for insulation installment is placed upside down resting on its top
rim so that glass wool insulation may be shot into it from its under or bottom
side 113. Typically, the spa 111 at this stage will comprise a spa shell 115
(Fig. 5) attached to a surrounding frame 117 with exterior paneling 119
attached to the frame 117 and with all spa equipment such as pump, filter,
heater, jets, and controls installed. The surrounding frame 117 may include,
for example, a base frame, formed for example of perpendicularly or
gularly arranged wooded studs 121 as shown in Fig. 4. The spa will
also lly e a “firewall” 123 (Fig. 6), which, in one embodiment, may
be a sheet of black ated polypropylene that separates the equipment
compartment of the spa from the tub area, similar to the ll in a car. Such
a sheet 123 may be cut on a Numerical Controlled (NC) Router to the proper
shape and to create holes, e.g. 124, for the plumbing pipes, e.g. 125 (Fig. 5),
and electronics to pass through.
In a first step according to an illustrative process, illustrated in Fig. 5, suitable
batting al 127, for example, such as polyester g, is installed to
block the firewall openings and other openings as necessary or desirable. A
spray adhesive may be used to secure the g in place. Additionally, if
d, masking tape may be used to block other small gs, and Kraft
paper or other shielding may be placed around the spa exterior to protect
decorative paneling 119.
In a next step, a sealing plate 129, shown e.g. Figs 4 and 7-9, is installed by
lowering it onto the spa frame members 121. In one embodiment, this g
plate 129 is fabricated from a flat interior sheet 131 surrounded by a rim 133.
In one embodiment, the flat sheet 131 may be attached to the rim 133 by
screws or other fasteners. In one embodiment, the flat sheet 131 may be
wood, such as plywood, or fiberglass, and the rim 133 may be a metal, such
as, for example, aluminum. The shape of the sealing plate 129 is selected to
conform to the shape of the spa bottom in illustrative embodiments.
A number of hinged doors or door “sliders” 135 are positioned on the top
surface 137 of the flat sheet131. Each hinged door 135 is strategically
positioned at a location where it is desired to inject the insulative glass wool
al. In one ment, the doors 135 are positioned to be over the
deeper parts of the spa interior in order to allow optimum filling of the spa 111.
In one embodiment, a plate lifter 151, e.g., Fig. 4, comprising, for example, a
chain hoist with wheels riding on a ceiling l beam or other track, may be used
to suspend, mechanically lift, move and position a larger sealing plate 129,
while smaller sealing plates 129 may be handled manually. The sealing plate
129 may be placed in an initial position above the spa 111 and then aligned.
In one embodiment, the alignment is by reference to locating the doors 135
over the deeper parts of the spa 111, as mentioned above. In one
ment shown in Figs. 8 and 9, a door 135 is hinged by a screw or other
device 136 to pivot in the plane of the top surface 137 to reveal a rectangular
2012/047068
g 141 wherein is disposed a rectangular shield or membrane 143 with
an “X” or other opening cut or othenivise formed in it. in one embodiment, the
flexible shield 143 may be fabricated of rubber or a flexible plastic material.
Once the sealing plate 129 is in place, one of the hinged doors 135 is opened
and a blower tube 155 is inserted into the opening 157 above an internal spa
cavity to be filled, for example, as illustrated in Fig. 10. The operator 159 may
then employ manual assistance from other workers to hold the seal plate 127
in place against the spa unit’s frame members, eg. 121. Of ,
mechanical means may be provided in other embodiments to hold the seal
plate 129 in place. Once the area beneath the blower tube 155 is visually
detected to be filled, the blower 155 is turned off, and then another seal plate
door 135 is opened, the blower tube 155 inserted, and the area beneath the
tube 155 filled. This process is repeated for all the seal plate doors 135 until
the spa’s internal cavity or cavities, e.g., 130, are completely filled.
After filling, the seal plate 129 is removed, revealing the “filled” spa unit 111
as shown in Figs. 4 and 11-12. The glass wool insulation 116 is then packed,
pushed or tamped down by hand approximately one half inch, as shown in
Fig. 12. Any excess glass wool 116 is removed from the intake and exhaust
cavities, which are the s for cool air to the spa’s pumps and exhausts for
heat from the pumps. Glass wool 116 is also removed from the top surface
area of the frame member studs 121. Any excess glass wool is also blown
from the spa equipment compartment area ing, for example, an air hose
and subsequent vacuuming.
As shown in Figs. 13 and 14, a sheet of plastic 161 is next placed onto the
pedestal frame, ed and stapled at its edges 163 flush with the pedestal
edge. In illustrative ments, the plastic sheet 161 may be either ABS or
Polyethylene. The plastic sheet 161 seals the bottom of the spa 111 so that
the glass wool insulation will not fall out. Any excess plastic around the edges
163 of the spa 111 may be trimmed off using a router or other tool.
Those skilled in the art will appreciate that various adaptations and
modifications of the just described preferred embodiment can be configured
without departing from the scope and spirit of the invention. Therefore, it is to
be understood that, within the scope of the appended claims, the invention
may be practiced other than as ically described herein.
