DETAILED DESCRIPTION
Fig. 1 illustrates a portable spa 11 having a spa shell 13, side panels, e.g., 15, 17 and
tapered corner fascia , e.g., 19, 21, 23. The spa shell 13 has a generally rectangular rim 12
about its upper periphery and includes various features such as jets, e.g. 25, 27, a filter
compartment 29 and a remote control 31. As may be seen, the lower edges 33 of the side panels
, 17 do not extend to the bottom edges 35 of the corner pieces 19, 21, 23 but rather terminate
at a distance “d” (Fig. 2) above the slab, deck, ground or other surface 30 on which the spa rests,
such distance “d” being, for example, 6 inches in one embodiment. In the illustrative
embodiment, the corner pieces, e.g., 19, 21, 23, are slightly spaced above, and do not contact, the
surface 30. Additionally, as shown in Figs. 30 and 31, the side panels 15, 17 are trapezoidal in
shape in one illustrative embodiment.
The spa 11 further includes a base pan 39 shown in Figs. 2, 4, and 5. As may be seen,
the lower eral side surfaces 37 of the base pan-39 are ed inwardly or swept back
from the side panel edges 33 to provide a pedestal effect, giving the appearance that the spa 11
contacts the floor 35 only at its four s and at the recessed edge 36 of the base pan 39. The
spa base pan 39 itself has four corners 40, each of which lies within and is concealed by a
respective corner fascia piece, e.g. 19, 21, 23. As seen in Fig. 4, the bottom of the base pan 39
further includes a grid work of rectangular areas 41 which e recessed fins or al
separators” 43. The grid work is defined by dicularly disposed ribs 45, 47, whose flat
bottom surfaces also rest on the surface 30. The rib and thermal separator structure on the
bottom of the base pan 39 minimizes the surface area of the base pan 39 which is in contact with
the surface 30 and, hence, reduces heat transfer from the spa 11 to the surface 30. In one
embodiment, a wavelike shape is imparted to the ribs, assisting in the minimizing the contact
area.
As shown in Figs. 2 and 3, in order to support the spa shell 13, vertical support
members 51 are provided to which are attached angled force transfer members 53, for example,
by gluing, snap-fitting, or other fastening mechanism. Fig. 6 particularly shows the interfitting
relationship of the base pan side surface 37 and the force transfer members 53 according to an
illustrative embodiment. As may be seen, the side surface 37 has an inner horizontally disposed
top step 42 and a horizontally ed lower step 44. The angled force transfer member 53
includes a stepped edge 46 shaped to mate with the step 42. The stepped edge 46 forms into an
angled surface 48, which rests on the swept back e 37. The angled surface 48 continues
into a second step 43, which mates with the lower step 44. A slot or l 50 is further formed
in the base pan 39 and snugly receives a foot portion 34 of the angled force transfer member 53.
Mating surfaces of the base pan surface 37 and the force transfer member 53 may be glued, snap-
fitted, or ise fastened together in position in various embodiments.
In one embodiment, the vertical support member 51 and the angled force transfer
member 53. may be fabricated of extruded ABS plastic and injection molded ABS plastic,
respectively. The base pan 39 may be a thermoformed ABS plastic sheet. Other materials and
fabrication techniques may of course be used in other embodiments.
In one embodiment, the force transfer member 53 may be a two piece component
comprising respective halves 131,133, as shown in Figs. 7 to 15. The halves 131, 133, are mated
together utilizing two tabs 141, 143, formed on the first half 131 and two tabs 150, 151 formed
on the second half 133. These tabs 141, 143; 150, 151 may be seen in Figs. 11 and 10,
respectively.
As r shown in Fig. 10, the interior 137 of the first half 131 may have height
markers, e.g. “29”, “33”, “36”, “38” molded or formed n or applied thereto and d
adjacent respective slots 139a, 139b, 139c, and 139d to indicate the particular spa rim height
which can be accommodated by utilizing a particular slot. In operation, the two tabs 150, 151 on
half 133 (e.g. Fig. 10) slide into one of the four groove pairs 135a, 134a; 135b, 134b; 135c, 134c;
135d, 134d, of the respective outer side surfaces of the first half 131 to select a particular height,
while the tabs 141, 143 enter into a pair of holes or apertures 147, 149 (Fig. 9) of the second half
133. Thus, the first half 133 can be telescoped between positions , , , to
increase or decrease the length of the angled force transfer member 53 and can be locked in
position by the tabs 150, 151, as further described below.
The manner in which the first and second halves 131, 133 are ed together is
further illustrated in Fig. 7. As may be seen, the tab 150 is riding in the second groove 135c.
The tab 151 is also riding in a generally parallel groove 134c on the opposite side of the first half
131. At the same time, the tabs 141, 143 of the first half are passing through grooves 139b, 140b
(Fig. 10) of the second half 133, thereby selecting the height of inches. When the tabs 150,
151, reach the end of the respective grooves 135c, 134c, they snap down over the side surface
136 of the component 131, e.g., as shown in Fig. 12, to hold the respective halves 131, 133
together. At the same time, the tabs 141, 143 enter a pair of the slots 147, 149, as rated in
Fig. 12, to further hold the assembly together. It may be noted that Figs. 12 and 13 illustrate the
inch assembly position, s the assembly shown in Fig. 7 would result in tabs 150, 151
being positioned one groove up (135c, 134c) and the tabs 141, 143 being positioned one slot
down from the positions shown in Figs. 12 and 13.
As shown in Figs. 10 and 11, for example, the first half 131 has a tongue 171 and a
cavity 174 formed in its or, and the second half 133 has a cavity 172 and a tongue 173
formed in its interior. When the first and second halves 131, 133 are mated together, the tongue
171 on the or of the first half 131 fits into the cavity 172 in the second half 133, while the
tongue 173 of the second half 133 fits into the cavity 174 formed in the first half 131. The first
half 131 further has an open or “cut-out” area 162 of rectangular cross-section formed n
(Fig. 7). In one embodiment, the area 162 has a shape identical to that of area 161 (Fig. 9).
onal open or hollow areas, e.g., 164 and area 165 (Fig. 8), are formed in the components
131, 133 to capture foam sprayed into the interior of the spa shell to thereby create a rigid
foam/plastic structure.
As shown in Fig. 8, the illustrative angle force transfer member 53 has an upper
receptacle of generally rectangular cross-section formed as a part thereof having a rectangular
rim 47 and a hollow interior 143. First and second u-shaped projections 201, 202 are formed in
the hollow interior 143. In one embodiment, the lower end of a vertical t member 51 is
configured to snugly mate or snap fit with the structure of the receptacle 141.
The illustrative embodiment is further constructed such that each side panel 33 may
be slid into position and retained in place without abutting or being attached to the corner pieces
19, 21, 23 or other spa structure. For this e, corner piece groove ures 65 are
provided as shown in Figs. 16 and 17, and three panel clips 69 are positioned along a lower
surface 72 of the base pan 39, as shown in Fig. 18. While three panel clips 69 are shown in Fig.
18, the number of clips could be one, two, or more in various embodiments.
Fig. 16 illustrates attachment of one of the tapered corner pieces 19 to respective
vertical support members 51 using a number of aped brackets 105. A first leg of each
bracket 105 attaches to the support member 51 and a second leg attaches to the corner piece 19.
The length “L” of the first leg of each bracket 105 increases as the edge 107 of the corner
piece 19 tapers away downwardly. In one embodiment, the angle 6 (Fig. 17) between the corner
piece’s tapered edge 107 and the vertical is an acute angle, for example, such as six or seven
degrees. The increasing bracket length effectively defines a gap or groove 65 between the
brackets 105 and the corner piece 19 which lies along the dashed line 109, effectively paralleling
the tapered e edge 107. In the illustrative embodiment, the same type of groove 65 is
formed by ed brackets 105 associated with each of the other three corner pieces,
e.g., 21, 23.
The ure and operation of the panel clips 69 is further illustrated in Figs. 19-27.
Each panel clip 69 includes a pivot component 73 (Figs. 23, 24) and a latch component 75
(Figs. 21, 22). The latch component 75 has a hook-shaped back 79, which is unitarily formed
with a front portion 80 having first and second lips 81, 83, whose inner surfaces define a
channel 85. The hook-shaped back 79 includes a slot 87 and an elongated opening 89.
As shown in Figs. 23 and 24, the pivot component 73 has an arcuate back surface 78
from which project two bosses 120 through which are formed tive holes 77. As illustrated
in Figs. 28 and 29, respective screws or other fasteners 82 are ed through the holes and into
a side surface 72 of the molded base pan 39. The bosses 120 cause the e back surface 78
to be spaced apart from the side surface 72 such that the hook shaped back 79 of the pivot
component 73 can be slid into the latch component 75. Thereafter, the latch component 75 may
be pivoted from the open position shown in Fig. 19 to the locked position shown in Figs. 20, 28,
and 29 in which the channel 85 is oriented vertically so as to retain and prevent downward
movement of the bottom edge of a panel 33 while allowing the panel 33 to move lly.
Figs. 25-27 illustrate the operation of the panel clips 69 in more . Fig. 25 is a
back View of the clip 69 in the locked position of, e.g., Figs. 20 and 28. In this position, the right
boss 120 of the pivot component 73 extends through the opening 89, and the left boss 120
extends through the slot 87. Hence, the latch component 75 cannot pivot due to the abutment of
the bosses 120 with the respective adjacent surfaces of the opening 89 and the slot 87. In this
position, in an illustrative embodiment, the screws 82 have further been tightened down to hold
the components 73, 75 in the locked position.
Fig. 26 is also a back view of the clip 69, but in this case, the screws 82 have been
unloosened slightly, and the latch component 75 has been moved to the right such that the left
boss 120 has moved out of the slot 87, and the right boss 120 has moved into position over a cut-
out area 123 formed in the latch component 75. In such position, the latch component 75 is free
to pivot with respect to the pivot component 73.
Fig. 27 is a top view of the clip 69 after the pivot component 75 has been pivoted to
the unlocked on of Fig. 19. In this position, the right boss 120 has pivoted into the cut out
area 123 of the latch component 75, and the left boss 120 lies adjacent an outer leg 124 of the
latch component 75.
The structure thus far described facilitates a side panel mounting method illustrated in
Figs. 30 and 31. As shown in Fig. 30, the spa 11 is positioned or raised off the mounting
surface 30. A trapezoidal side panel 33 is then inserted upwardly such that its upper corners and
its sides slide into the grooves 65 defined by brackets 105 and the corner pieces 19, 21. The
panel 33 is then slid further upwardly until its top edge 102 passes behind the rim 12. At that
point, the panel clips 69 are each moved into the locked position shown in Figs. 20, 28, and 29
and the screws 82 are tightened to locking on.
The just-described side panel mounting method has the advantage that the side
panels 33 are not y attached to the corner pieces e.g. 15, 17, 19 or other structure, and
therefore the panels 33 may expand and contract with temperature variations without the exertion
of forces which would distort or otherwise damage the panels 33 if they were not free to expand
or contract vertically or horizontally. This method has particular advantages in certain
embodiments where the corner pieces, e.g., 17, are made of plastic and the side panels 33 are
constructed of wood or of a plastic which has a cient of expansion which is different than
that of the corner piece plastic. In such embodiments, the side panels 33 may expand or ct
as much as half-inch in very hot or cold conditions, which would likely damage the spa ure,
