Description

CA 02828555.2013-09-26 MOLDED STACKABLE BATHTUB WITH APRON AND MOUNTING ASSEMBLY
BACKGROUND OF THE INVENTION
[0001] This application claims the benefit of United States Provisional Patent Application Serial Number 61/708,079 filed October 1, 2012, the complete disclosure of which is hereby expressly incorporated by reference.

[0002] This invention relates to a bathtub having an integrated front apron, and in particular, to a bathtub having a front apron and can be stacked in a nested arrangement for shipment, and further includes a strip and locking clip assembly for use in mounting the bathtub when installed.

[0003] Bathtubs that are molded with an integral apron front typically include apron supports or struts extending between the apron and tub to stabilize the apron. However, such apron supports prevent this design of tub from being nested or stacked for shipment. Accordingly, such bathtubs are typically packaged individually in a single carton. Although this makes it easy for a homeowner to easily purchase, pick up, deliver, and install such a bathtub, it is not convenient for a contractor working on a job site with a large number of bathtubs to install, such as in a high rise hotel. The contractor must take each individual bathtub to its location, or find some place to stack the bathtubs, and then unwrap each bathtub and dispose of the packaging. This can be very inconvenient and time inefficient.

[0004] Accordingly, it is an object of the subject invention to provide a bathtub having a front apron that can be nested and stacked for easier shipment and delivery to the job site. A further object of the invention is to reduce packaging weight and waste by shipping and delivering bathtubs in a nested stacked arrangement rather than individually wrapped. A further object of the invention is that skids of the nested and stacked bathtub can be double stacked, which in one embodiment would provide 20 bathtubs in the same footprint of five standard bathtubs on a truck.

[0005]
It is a further object of the invention to provide a system and components for mounting and stabilizing an apron not having supports or struts, when installing such a tub at the desired installation location.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0038] For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings, which are described below. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. The invention includes any alterations and further modifications in the illustrated devices and described methods and further applications of the principles of the invention, which would normally occur to one skilled in the art to which the invention relates.

, ,

[0039]
Now referring to Figure 1, a standard molded bathtub is shown, generally indicated as 10, and in an inverted position. Bathtub 10 includes an integrally molded front apron 12 and supports or struts 14 attached to and extending between apron 12 and a bottom 16 of a basin 17 of bathtub 10. Also attached to and extending down from bottom 16 are feet 18 on which bathtub 10 stands upon when installed. Bathtub 10 also includes an upper rim or ledge 20 extending around the top thereof and to which apron 12 is attached.

[0040]
As discussed above, bathtub 10 is ideal for individual packaging and sale, and struts 14 provide ample support for apron 12 when the unit is installed.
However, as should be appreciated by one skilled in the art, struts 14 preclude bathtub 10 from being nested and stacked together as the rim 20 of a bathtub to be shipped over top of bathtub 10 would encounter the struts 14 on the lower bathtub and prevent stacked nesting of the tubs.

[0041]
Now referring to Figure 2, one embodiment of a molded bathtub in accordance with the subject invention is shown, generally indicated as 110.
Bathtub 110 includes an integrally molded and attached front apron 112.
However, instead of struts or supports 14 as found on bathtub 10, bathtub 110 only has end gussets 114. Also, similar to bathtub 10, bathtub 110 includes a basin 117 having a bottom 116 from which support feet 118 extend, and an upper rim or ledge 120 to which apron 112 is attached. As is shown in Figure 2, gussets 114 extend between and are attached to apron 112 and rim 120.

[0042]
Now referring to Figures 3 and 3A, a mounting assembly used in installing bathtub 110 is shown, generally indicated as 130. Mounting assembly 130 includes a furring or mounting strip 132 and a clip or bracket 134. As shown in Figures 4-6, furring strip 132 has a generally rectangular configuration including a top side 140, a bottom side 141, side edges 142 and 143, and ends 144 and 145.

In the embodiment shown, furring strip 132 does not include any holes or irregularities; however, it should be realized that mounting holes may be used to mount clip 134 or recesses added to make flush mounting of clip 134. Furring strip 132 may be made from plywood or a laminated wood material, or alternately, a metal, such as aluminum or stainless, or a suitable plastic, may be used for the furring strip.

, ,

[0043] Details of clip 134 are shown in Figures 7-10. In the embodiment shown, clip 134 has a generally L-shaped configuration including a shorter upstanding leg 150 and longer lower leg 152 having a generally wedge-shaped configuration 154 on the end thereof. Wedge shape 154 includes a back side 156, a front slope 158, a radius 159 between back side 156 and front slope 158, and a pointed front end 160. Clip 134 may be manufactured from an ABS plastic and adhered to furring strip 132, or alternately, may be attached with fasteners or other well known attachment means. In addition, clip 134 may be manufactured from other materials, such as aluminum or stainless steel.

[0044] Clips 134 are attached or otherwise assembled with furring strips 132 as shown in Figure 3A. The bottom side 141 of the furring strip is placed on top of bottom leg 152 of clip 134, and side edge 143 (or alternately side edge 142) is placed against leg 150 of clip 134 as shown. This creates a gap 161 between back side 156 of the wedge shape 154 of clip 134 and the front side edge 142 of furring strip 132. Gap 161 is for receipt of the bottom end of apron 112 when installed at a site as discussed in further detail below.

[0045] Now referring to Figures 11 and 12, bathtub 110 is shown in an upright position wherein it can be seen that basin 117 defines an open space or cavity 122 for holding water for bathing. In addition, further detail of gussets 114 is shown in Figures 11-14. Gussets 114 include a long leg 162 attached to apron and a short leg 164 attached to rim 120. Gusset 114 also includes a center span 166 having a notch 167 where apron 112 and rim 120 meet. Gusset 114 may be manufactured from an ABS plastic or corrosion-resistant metal, such as aluminum or stainless steel.

[0046] Now referring to Figures 13 and 14, an arrangement showing seven bathtubs 110 nested and stacked on a pallet 170 is shown. As can be seen, the bathtubs 110 stack quite nicely and shipping spacers 172 are provided in each corner attached to or placed on the bottom side of rim 120 so that the rim 120 on the adjacent bathtub can rest thereon and also prevent rim 120 from encountering gussets 114. Shipping spacers 172 may be manufactured from a corrugated cardboard or plastic material or alternately, hard foam, wood, or other suitable material may be used.

[0047] Now referring to Figures 15-17, bathtubs 110 are shown nested and stacked in a double stacking arrangement of two sets of nested and stacked bathtubs. With this arrangement, 20 bathtubs can be stacked on a truck in the same footprint of five standard bathtubs. As an example, the present arrangement may allow a total of 600 nested and stacked bathtubs on a truck compared to standard bathtubs. The bottom set of 10 nested and stacked bathtubs 110 are contained within a combined pallet and shipping frame 180. Pallet and shipping frame 180 includes a lower pallet portion 182 similar to pallet 170 and an upper pallet portion 184, which is also similar to pallet 170. As is shown, the lower set of nested stacking bathtubs 110 rests on lower pallet portion 182, and the upper set of nested stacking bathtubs 110 sits on upper pallet portion 184. Extending between lower pallet portion 182 and upper pallet portion 184 are a number of vertical frame members 186. More or less vertical frame members may be used as desired.
Pallet and shipping frame 180 also includes angled frame members 188 to increase the stability thereof. The number, position, and orientation of angled frame members 188 may be varied as desired.

[0048] Now referring to Figure 21, bathtubs 110 are shown nested and stacked in a stacking arrangement of four sets of nested and stacked bathtubs 110.
In the example shown, each set includes seven nested bathtubs stacked together for a total of twenty-eight bathtubs being stacked one upon the other. The bathtubs 110 in Figure 21 are shown stacked in the same combined pallet and shipping frames 180 as shown in Figures 15-17. Such an arrangement allows for very efficient stacking of bathtubs in a warehouse, ship, etc.

[0049] Now referring to Figures 18-20, installation of bathtubs 110 and use of mounting assemblies 130 is shown. As shown in Figure 18, the mounting assembly is mounted to the floor with side edge 143 of furring strip 132 facing towards the back wall and clip 134 facing outwardly. Mounting assembly 130 may be nailed, screwed or attached with an adhesive. Mounting strip 130 is used to provide additional support to the apron since struts 14 have been removed to facilitate the nested stacking. Before mounting assembly 130, it is preferable to mark the subfloor based upon the dimensions of the bathtub to be installed.
The front line of furring strip 132 may be marked on the subfloor, and the furring strip secured firmly behind the line. The bathtub is installed in accordance with instructions with the bottom of apron 112 positioned in gaps 161 of mounting assembly 130. (See Figure 19.) Apron corners should be guided into the gap and once installed therein, the installation should be checked with a square 195 to verify that the apron is set all the way in at 900. (See Figure 20.) If the apron is not at 900, then the bathtub should be removed, and the location of the furring strip should be moved forward or backward accordingly. Thusly installed, the mounting assembly holds the apron straight and securely during use thereof.

[0050]
