SILL TRIM ASSEMBLY BACKGROUND OF THE INVENTION This invention, in general, relates to the construction or home improvement field and more specifically relates to an improved, inexpensive and easy to install decorative trim strip assembly for windows and similar uses.

DESCRIPTION OF THE PRIOR ART The following prior art patents are known to applicant:

U.S. Pat. No. 627,960 to Brower; U.S. Pat. No. 1,880,282 to Rithner; U.S. Pat. No. 2,240,95l to Guignon; U.S. Pat. No. 2,370,638 to Crowe; U.S. Pat. No. 3,217,453 to Medow; and U.S. Pat. No. 3,293,819 to Heirich.

While the art above, in general, shows facing or trim members which can be secured in place in a building, none of them show the unique connecting members disclosed in this application or the unique transverse ribs which enable the device to be cut to size on the job site. Furthermore, all attachment means are concealed when the unit is installed.

SUMMARY OF THE INVENTION It has been'discovered that a new and improved trim and facing assembly can be constructed by providing an elongate base member which can be readily secured to an existing building and clips which fit around and are secured to the base member.

These clips are provided with outwardly directed flanges having serrations thereon and in this fashion, a U-shaped cover member can be snapped into place over the base and the clips with the serrations preventing removal.

It has also been discovered that the utility of the trim assembly is enhanced if a series of spaced, transverse walls or ribs are provided both on the base and between the walls of the cover member. The respective ribs and walls are aligned and in this fashion, the assembly can be cut to size while still presenting a closed end wall at both ends.

Accordingly, production of an improved trim assembly of the character described becomes the principal object of this invention with other objects thereof becoming more apparent upon a reading of the following brief specification considered and interpreted in view of the accompanying drawings.

OF THE DRAWINGS FIG. 1 is a top plan view of the cover strip.

FIG. 2 is a top plan view of the base strip.

FIG. 3 is a sectional view taken along the lines 3-3 of FIG. 1 partially broken away and showing the cover in place on the base.

FIG. 4 is a sectional view taken along the lines 4-4 of FIG. 1.

FIG. Sis a perspective view of the improved clip.

FIG. 6 is a perspective view partially broken away and showing the interconnectionbetween the base, the clip and the cover.

Considering first then FIGS. 1, 2 and 5, it will be seen that the assembly, which is the subject of this invention, includes three main components. These components are the cover member 10 which has a decorative outer surface 11, the base member 20 and the

clips

30,30.

Considering first the cover member 10 in greater detail and referring to FIGS. 1, 3 and 6, it will be seen that the same is elongate and generally rectangular in planar configuration. As mentioned above, the outer surface of the cover 10 preferably has a decorative surface 11 formed in a rough pattern to simulate stone.

With particular regard to FIG. 6, it will be noted that the cover 10 has generally U-shaped cross-sectional configuration including opposed sidewalls l2 and 13 and a top surface 11 as well as

end walls

15 and 16. In the preferred form of the inven tion, the cover 10 will be made of plastic or other suitable lightweight, inexpensive material.

Finally and considering FIG. 3, it will be seen that the cover member W has a series of transverse interior walls MAM spanning the distance between the sidewalls i2 and I3 and presenting a finished appearance similar to that ofthe end wall NJ, for example, for purposes which will be described in greater detail below.

Turning next then to the base member 2t it will be seen that the same also has a generally rectangular planar configuration corresponding in its general dimensions to the dimensions of the cover W as will be clearly seen by comparing FIGS. 3 and 2 of the drawings.

The base 24 also has sidewalls 2i and 22 extending along its longitudinal length and interconnected by

end walls

23 and 2 3. Also, this bottom member has a series of

transverse ribs

26,26 spanning the distance between sidewalls 2i and 22 and spaced complementally with the transverse walls 14,114 of the cover member 10. in this regard, for example, assuming one measures from the right-hand end of both the cover 10 and base 20, the first rib 26 will be spaced the same distance from the end of the base as the first wall is will be spaced from the end of the cover. Successive ribs and walls will also have similar spacing. I

Base 2i also has a series of

apertures

28,28 in its bottom surface 25 with these apertures serving to permit the base to be secured to the supporting surface upon which it will rest by conventional screws.

Finally, the sidewalls El and 22 of the base have a plurality of recessed areas such as 211a and 22a which are designed to receive the clip 30 as will be more fully described. Associated with these recessed areas are screw mounting means 27,27 the purpose ofwhich will also be described more fully below.

Turning next then to the clip 36 and referring particularly to FIG. 5, it will be seen that the clip is generally U-shaped and consists of a base 311 and opposed

legs

32 and 33. These legs terminate in outwardly and downwardly directed

flanges

32a, 33a, each of which has a serrated edge such as 32b. Finally, the clip has a pair of apertures M34 in the base 31 and the dimension between the

walls

32 and 33 ofthe clip 30 is slightly greater than the external transverse dimension of the base 20 adjacent one of the recessed or

cutout areas

21a,22a. This permits the

legs

32 and 33 to flex slightly thus facilitating installation of the cover.

In use or operation of the improved assembly, it will first be assumed that the dimension of the area to be covered by the sill has been ascertained. At that time and assuming that this dimension is less than the dimension of the standard production model unit, it is merely necessary to cut off the base 20 and the cover l0 adjacent one of the transverse walls. This will have the effect of presenting a finished end surface when the device is assembled since the combination of a wall M and a rib 26 will result in a finished product resembling the normal end wall 15 when the unit is assembled.

In this regard, the greater number of conventional windows, etc. fall within a range of certain dimensions and therefore, the placement of the

ribs

26,26 and walls M14 can be readily predetermined so that the assembly can be designed to fit virtually any existing window.

in this regard, it should be noted that a wide range of possible dimensions can be achieved by the unique arrangement of the walls MAM and

ribs

26,26. Thus, it will be noted that these walls and ribs are not spaced in equal distances and it is possible to cut off the cover and the base from either end with the spacing between the walls, for instance, enabling a wide range of different overall longitudinal dimensions to be achieved.

Furthermore, the

ribs

26,26, to a certain degree, and the walls 114,1 3, to a greater degree, provide increased stability and rigidity to the overall structure.

Continuing then with regard to installation and assuming that the base 20 and cover it) have been cut to size, at least a pair of

clips

30,30 will be secured to the base member 20 by placing them in the cutout areas 2lla and 22a as is clearly shown in FIG. 6. The depth of cutout or recessed areas 2141,2211 and the thickness of

legs

32 and 33 of the clips are such that when in place on the base the outer surface of walls 2i and 22 present a flush or uninterrupted surface. in this regard, it might also-be noted that the bottom of the base 261 also has a slightly recessed transverse area 25a associated with each of the recessed areas in the walls. in this fashion, due to the fact that the clip is a relatively thin metal piece, it can be put in place as shown in PKG. 6 and enable the bottom surface of the base to be substantially smooth and uninterrupted. Once the clip has been placed in position, it will be secured to the base by conventional screws utilizing the

apertures

34,34 and mounting

members

27,27 in the base.

Once the base and the clips have been secured in place, the base itself can be attached to the supporting surface by using conventional screws and the holes 2&2t3 which are provided in the bottom 25 of the base.

Following firm anchoring of the base in place, it is merely necessary to snap the cover Ml! into place. As can be seen in F116. 6, the

flanges

32a and 33a of the clips are outwardly and downwardly directed and have serrated portions on their edges which will engage the interiors of the walls 112 and 13 of the cover it). These serrations will have a tendency to dig into these walls and prevent removal of the cover 110 from the finished assembly.

Thus all the means for attaching the base to the support surface, the clips to the base and the cover to the base are completely concealed.

It has been shown, therefore, how, by providing a simple inexpensive, yet efficient three-piece assembly, a new and improved, easy to install trim assembly can be achieved.

it should be noted that while certain materials have been referred to in the foregoing specification, that the invention is not intended to be limited to the use of any specific material and any suitable lightweight material could be employed as an alternative.

While a full and complete description of the invention has been set forth in accordance with the dictates of the patent statutes, it should be understood that modifications thereof can be resorted to without departing from the spirit hereof or the scope of the appended claims.
