Description

FIELD OF THE INVENTION

The present invention relates to underlayment ventilation and moisture control. More particularly, the present invention relates to a ventilating sill elevating a wall partition from a floor surface to isolate the wall partition from moisture and humidity.

BACKGROUND OF THE INVENTION

Conventional walls or structures inside a building are prone to various environmental and interior building factors such as heat, moisture and humidity. Wall design can be optimized to control, prevent or manage these factors.

Water leaks, floods and water vapor are sources of moisture and humidity that can damage the wall structures. Basements are particularly at a higher risk of floods and water leaks because they are either completely or partially below ground level.

Moisture usually migrates up through the building from basements and crawl spaces, particularly where no vapor barrier is placed on or below floors, walls, structures or surfaces. Moisture can also condense when its ambient temperature is cooled to its dew point. At the dew point, surplus water vapor condenses and wets the nearest surface. In addition, wall partitions constructed over concrete surfaces are especially prone to moisture and humidity.

Vapor barriers and base plates may be used to isolate wall partitions. However, such barriers or plates may cause moisture and humidity to accumulate and become trapped beyond the barrier or plate and further damage the wall partitions. Attempts to resolve this issue have been made in the past such as the design Pat. Nos. US D727,533S and US D711,020S. These designs correspond to wall footers wherein the base surface comprises a plurality of cylindrical protrusions adapted to create a gap between the wall partition and the ground. However, in such designs, the wall partition lay flat on the device, thus restraining the moisture accumulated between the footer and the wall to escape. Furthermore, the protrusions are substantially thin, which limits a water flow in a flood event. The protrusions are also not aligned in the direction of the thickness of the wall thus creating an increased resistance since the water must change direction to avoid the protrusions.

Other prior art includes a product as disclosed U.S. Pat. No. 8,915,044. The patent '044 discloses a mounting clip creating a gap between a gypsum board and the ground to prevent moisture damage. In the event of a flood, such clip does not allow water to flow underneath the wall. Furthermore, moisture or humidity may remain trapped between the clip and the gypsum board. The accumulated moisture will thus increase damage to the wall over time. Moreover, such device is not adapted to support heavy loads.

There is thus a need for a ventilating sill to protect the wall partition from moisture and humidity while draining excess moisture and humidity.

Hence, in light of the aforementioned, there is a need for an improved system which, by virtue of its design and components, would be able to overcome some of the above-discussed prior art concerns.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A novel Ventilating Sill Plate will be described hereinafter. Although the invention is described in terms of specific illustrative embodiment(s), it is to be understood that the embodiment(s) described herein are by way of example only and that the scope of the invention is not intended to be limited thereby.

As shown in FIGS. 1 to 7, there is provided a ventilating sill 10 for elevating a wall partition 12 from a floor surface (not shown) to isolate the wall partition 12 from moisture and humidity that can emanate from the floor surface or be present thereon. The ventilating sill plate may be manufactured in any size as to conform to the dimensions of any type or format of wall. The ventilating sill may be adapted to a wall made from material such as, but not limited to, metal, wood, and the likes.

In some embodiments, the ventilating sill 10 comprises a block 14, a pair of slats 16 and at least one aperture 18. In other embodiments, the ventilating sill 10 may further comprise a screen mesh insect barrier 20.

The ventilating sill 10 is typically placed between the floor surface and the wall partition 12 to protect the wall partition 12 from moisture and humidity emanating from the floor surface or from water leaks or the like.

The block 14 generally defines a support surface 22 for receiving the wall partition 12 and a base surface 24 for contacting the floor surface. The support surface 22 is delimited by two opposite side surfaces 26 and is preferably sized according to the width of the wall partition 12. Preferably, the support surface 22 comprises a recess 32 mounted around the at least one aperture 18 for guiding any moisture and humidity towards the at least one aperture 18. The block 14 is preferably made from plastics, composites or metals. Understandably, any other materials may be used as known to a person skilled in the art.

The block 14 also comprises a plurality of spaced channels 28 extending between the side surfaces 26 to form channeled surfaces 30. The spaced channels 28 allow moisture, humidity, water leaks and the like to flow from one side of the wall partition 12 to the other to prevent their accumulation. The channels 28 are therefore generally perpendicular to the wall surface. The use of the ventilating sill 10 may therefore limit or prevent wall humidity and/or mold builds up. The ventilating sill 10 may further comprise a screen mesh insect barrier 20 positioned over the channeled surfaces 30 to provide a shield or barrier from pests and insects.

In a preferred embodiment, on each side surface 26, a slat 16 is mounted upwardly towards the wall partition 12 at a substantially right angle to the support surface 22 The slats 16 define a support area positioned on the support surface 22. The pair of slats 16 is generally adapted to guide the wall partition 12 onto the support surface 22. The pair of slats 16 may also comprise spring clips or any other fastener types for securing the wall partition 12 onto the ventilating sill 10, as known to a person skilled in the art. The slats 16 are preferably made from plastics, composites or metals. Understandably, any other materials and/or shapes maybe used as known to a person skilled in the art.

In a preferred embodiment, the support surface 22 comprises at least one aperture 18 communicating between the support area and an ambient environment. The aperture 18 aims at allowing the ventilation of the support area and the draining of any moisture and humidity therefrom, In some environments, it is preferable to have multiple apertures 18 to aim at further increasing the ventilation efficiency.

Now referring to FIGS. 7A and 7B, the aperture 18 in illustrated in more details. Specifically, the aperture 18 is preferably located at a junction point between the slats 16 and the support surface 22. In a preferred embodiment, a slope is defined between the surface 22 and the aperture 18 as to guide the water to the outside environment. The apertures 18 are preferably linearly disposed along the length of the sill 10. The distance between consecutive apertures may be varied depending environmental parameters, such as level of risk of flooding event and percentage of humidity of the ambient air where the wall is to be installed.

Now referring to FIGS. 8A and 8B, another embodiment of the invention is illustrated. In such an embodiment, the wall partition and ventilating sill are integral, such as made from a sole piece of material 10(12), preferably plastics, or composites. Understandably, the material must sustain the force and weight of the above installed wall. The sill, or ventilating wall partition 10(12), comprises channels 28 to generally allow water to flow beneath the wall. The flow of water beneath the wall aims at rendering the entire wall partition to be mold proof For instance, some buildings located in flood prone regions may benefit from such flow of water. In events where flooding or high level of water is generally expected, flowing of water may further reduce damages to the walls or to the wall structure. In a preferred embodiment, such ventilating sill may be used to support division wall or other walls closes to a potential source of water.

In another embodiment, the ventilating wall partition may comprise a plurality of liquid permeable portions and a plurality of load carrying portions vertically superposed and placed in alternation. Each liquid permeable portion may comprise a plurality of spaced apart channels. The plurality of liquid permeable portions is intended to increase the flow of water in a situation where a water level is substantially high. In such a case, water will flow in parallel through both liquid permeable portions.

Now referring to FIG. 9, a further embodiment of a ventilating sill is shown. In such an embodiment, the ventilation sill comprises wide channels 35. Such wide channels 35 aims at increasing the flow of liquid under the wall structure. Accordingly, the channels may have different shapes or dimensions for different configurations.

Furthermore, although the present invention may be used with various objects, such as wall partitions, for example, it is understood that it may be used with other partitions or structures. For this reason, expressions such as “wall partition”, “wall”, “partition”, “structure”, etc. as used herein should not be taken as to limit the scope of the present invention to these construction objects in particular. These expressions encompass all other kinds of materials, objects and/or purposes with which the present invention could be used and may be useful, as can be easily understood.

While illustrative and presently preferred embodiment(s) of the invention have been described in detail hereinabove, it is to be understood that the inventive concepts may be otherwise variously embodied and employed and that the appended claims are intended to be construed to include such variations except insofar as limited by the prior art
