U.S. Cl. 52-473 7 Claims ABSTRACT OF THE DISCLOSURE The panel unit is intended primarily for use as a window shutter and includes a body member molded of a plastic material and integrally formed with a center louvered panel section of a rectangular shape and stile members of a channel shape in transverse section. The base sections of the stile members are spaced forwardly from the front face of the panel section with the inner leg sections of the stile members joined at the rear sides thereof with the panel section. Each end of an inner leg section at substantially the junction thereof with the base section of a corresponding stile member is formed with a longitudinally extended slot. A header rail or transverse frame member for each end of the body member is of a right angle shape in transverse section and is formed relative to the body member for interlocking engagement therewith at the slotted ends of the stile members so that the end frame members have front surfaces located in a plane common to the front surfaces of the base sections of the stile members. The side surfaces of the header rails extend normal to the outer leg sections of and across the ends of the stile members so as to form with the stile members a continuous perimetric frame unit for the panel section of the body member.

Summary of the invention The invention provides a molded body member formed of a plastic material and having a center panel section of a rectangular shape integrally formed with stile or side frame members. The panel section may be formed with transversely extended and joined louver portions to give a window shutter appearance. The body member may be made in continuous lengths of from six to ten feet and cut to a desired length on the job to accommodate or fit the window assemblies with which the panel unit is to be used. After being cut to length it is only necessary to slot the stile members at the ends thereof to provide for an interlocked engagement of the header rails or end frame members with the body member to form a continuous perimetric frame unit for the panel section and a completed panel unit having the same appearance as a usual wooden window shutter.

The end frame members are constructed to provide lateral rigidity at the corners of the perimetric frame so that the panel unit may be firmly secured to a wall surface without distortion of the end frame members. The panel unit may be made with differently colored plastic material to match a desired color scheme. Painting is thus entirely eliminated and by virtue of the plastic composition of the panel unit deterioration from weather exposure is reduced to a minimum. The panel unit is thus economical in cost, readily formed to a desired length, resistant to denting or chipping, and long lasting with a minimum of maintenance attention.

Detail description of the invention Further objects, features and advantages of the invention will become apparent from the following description atent 3,455,879 Patented July 15, 1969 ice taken in connection with the accompanying drawings wherein:

FIG. 2 is a front perspective view of the panel unit;

FIG. 3 is an exploded foreshortened perspective view of the panel unit shown in FIG. 2;

FIGS. 4, 5, 6, 7 and 8 are enlarged sectional detail views taken respectively on lines 4-4, 55, 6-6, 7-7 and 8-8 in FIG. 2. showing the assembly relation of end frame members and a body member which form the panel unit; and

FIG. 9' is a perspective view of a panel unit, with portions broken away, adapted for use as a picture or mirror supporting frame.

With reference to FIG. 1 of the drawings the panel unit of this invention, designated generally as 15, is illustrated as being a decorative shutter for a house window assembly 16. As is Well known decorative shutters are secured directly to the wall 17 of a house to opposite sides of a window assembly to simulate an open position of the usual hinged type shutters that are movable to both window opening and closing positions.

The panel unit 15 (FIGS. 2 and 3) includes a body member 18 molded of a plastic material and integrally formed with a center panel section 19 of a rectangular shape and side frame or stile members 21 of a channel shape having leg sections 22 and 23- and a base section 24. The panel section 19 lies in a plane normal to the planes of the inner leg sections 22 and parallel to and spaced rearwardly from the common plane of the base sections 24 of the stile members 21.

As shown in FIGS. 2 and 4 the panel section 19 is formed with transversely extended shutter members 26 joined at their opposite ends with the rear or free ends of the inner leg sections 22 and joined together along their adjacent sides by connecting portions 27 to provide a continuous panel front surface 28 wherein the shutter members 26 are inclined forwardly and downwardly to simulate partially closed positions therefor. The opposite ends of an inner leg section 22 (FIG. 3) are formed with longitudinally

extended slots

29 and 31 at substantially the junction thereof with corresponding base sections 24. The slot 29, which for convenience will be referred to as the upper slot, is of a shorter length than the lower slot 31 and with the

slots

29 and 31 being in alignment longitudinally of an inner leg section 22.

To enclose the panel section 19 within a perimetric frame which includes the stile members 21 there are provided upper and lower header or

end frame members

32 and 33, respectively. The upper header member 32 (FIG. 3) is of a right angle shape in transverse section having a downwardly extended front leg portion 34 and a rearwardly projected top leg portion 36. The top leg portion 36 has a length equal to the transverse dimension of the body member 18.

The front leg portion 34 has a central section 37 of a length substantially equal to the transverse dimension of the panel section 19 of the body member 18 and end sections 38 of a reduced width and depressed rearwardly from the front surface of the leg portion 34. Each end section 38 is depressed a distance substantially equal to the thickness of the base section 24 of a stile member 21 and is of a length slightly less than the spacing between the

leg sections

22 and 23 of a stile member. It is to be noted also that each depressed end section 38 is of a thickness across the underside of the top leg portion 36 at a position inset from the adjacent terminal end of the top leg portion a distance equal substantially to the thickness of an outer leg section 23 of a stile member.

In the assembly of the upper header member 32 with the body member 18 the central section 37 of the front leg portion 34 is positioned between the inner leg sections 22 of the stile members 21 with the depressed end sections 38 located at the upper slots 29. When thus arranged and applying pressure manually on the top leg portion 36 of the header member 32 the end sections 38 are inserted within the upper slots 29 concurrently with the reception thereof and of the projections 39 between the

legs

22 and 23 of a stile member 21. As shown in FIG. 7 an end section 38 and projection 39 are thus positioned in a side by side relation with the inner surfaces of the corresponding base section 24 and outer leg section 23 of a stile member 21. The extent of insertion is limited by the engagement of the lip 41 formed by the top leg portion 35, with the base section 24 and outer leg section 23 of a stile member. This lip 41 (FIGS. 3 and 4) is in an overhanging relation with an end section 38 and projection 39.

As a result of this assembly the upper header member 32 is mechanically interlocked with the body member 18 with the front surfaces of the base sections 24 of the stile members lying in a plane common to the front surface of the front leg portion 34. Likewise, it is seen (FIG. 2) that the portion of a lip 41 corresponding to a projection 39 is flush with the outer surface of a leg section 23.

The header member 32 at the lower end of the central section 37 of the front leg portion 34 is provided with a rearwardly extended flange 42 (FIG. 6) which is adapted to engage the underside 43 of the upper shutter member 26. The upper header 32 thus forms an end frame member for the body member 18 which is continuous with the stile members 21.

The lower header member 33 is constructed similarly in all respects to the upper header member 32 (FIG. 3) except for the center section 37A, and sections 38A and projection 39A of the front leg portion 37A being of a greater width relative to the corresponding parts of the upper header 32. Similar numerals of reference, used in the above description of the upper header member 32, with the suffix A are therefore used to indicate like and corresponding parts in the lower header member 33.

In the assembly of the lower header member 33 with the body member 19 the end sections 38A and projections 39A are received within the lower ends of the stile members 21 by insertion of the end sections 38A Within the lower slots 31. As shown in FIG. 8, on completion of this assembly, the end sections 38A and projections 39A are in a side by side relation with the inner surfaces of the base sections 24 and outer leg sections 23 of the stile members. The center section 37A of the front leg portion 34A (FIG. is formed at its upper end with an inwardly projected flange 42A adapted to engage the underside of the shutter member 26 which is first above the leg portion 34A.

It is contemplated that the body member 18 be made in varying lengths to provide for its being cut on the job to a desired length corresponding to the length of the window assembly 16 with which the panel units 115 are to be used. After the body member 18 is cut to length it is only necessary to cut the

slots

29 and 31 to provide for the mechanical interlocking of the header members 32. and 33 with the body member 18 to form a continuous perimetric frame for the panel section 19.

The panel unit at the corners thereof, is secured to the house wall 17 by screws, indicated at 44 in FIG. 1, extended through the base sections 24 and

end sections

38 and 38A for threaded engagement in the wall. By virtue of the projections 39A being engageable with the wall the

header members

32 and 33 are fully supported against being pressed inwardly or distorted as a result of such securement.

The panel unit thus provides a window shutter which is pleasing in appearance and of long lasting duration since it requires no painting, is not readily dented and does not crack or peel from Weather exposure.

FIG. 9 illustrates a panel unit 47 which is similar in all respects to the panel unit 15 described in connection withFIG. 2, except that the body member 48 of the panel unit 47 has a flat panel section 49. A mirror or picture (not shown) may thus be mounted on the flat panel section 49 and the panel unit 47 secured to an interior wall or door.

It will also be apparent from a consideration of FIGS. 2 and 9 that the center panel sections 19 and 49 may be eliminated and the stile members 21 formed separately for interlocking engagement with the end frame or

header members

32 and 33 to provide an open frame unit for surrounding a wall supported object or panel.
