Description:
SUMMARY OF INVENTION
The invention relates to a one-piece molded plastic shutter which can include central louvered panel sections which extend to marginal sections that have a peripheral flange. The invention relates to longitudinal channel portions which are hat shaped in cross section with out-turned flanges which are accessible for the purpose of sonically welding the channel members to the marginal shutter sections and provide a unitized assembly of the shutter and channel members. The channel members extend over a substantial portion of the length of the shutter and in addition to rigidifying the shutter, are employed for fastening purposes.
The invention also provides a mounting clamp which has a web with a pair of spaced legs adapted to receive the channel members. The clamps have an aperture so that the clamps can be mounted with a suitable fastener to a building wall prior to the assembly of the shutter on the wall. The legs of the clamp have outwardly diverging terminal portions which are hinged to the leg portions by narrow bands of metal. The terminal portions have inwardly extending barbs which grasp and securely retain the channel members to the clamp.
Further objects, features and advantages of the invention will become apparent from the following disclosure.

DESCRIPTION OF PREFERRED EMBODIMENT
Although the disclosure hereof is detailed and exact to enable those skilled in the art to practice the invention, the physical embodiments herein disclosed merely exemplify the invention which may be embodied in other specific structure. The scope of the invention is defined in the claims appended hereto.
In the drawings, FIG. 1 discloses a shutter generally designated 10 which includes central panels 12 which can be in the form of simulated louvers. The shutter includes vertical marginal sections 14 and horizontal marginal sections 16 and 18. The marginal sections have flanges 20 and 22 which form a continuous periphery for the shutter. As thus far described, the shutter can be of a one-piece plastic molded construction.
In accordance with the invention, the shutter is provided with elongated mounting channel members 26 which as best shown in FIG. 2 extend for a substantial portion of the vertical extent of the shutter 10. The channel members 26 are generally rectangular in cross section as shown in FIG. 3 and include out-turned flanges 30 to thus provide a hat-shaped appearance. The out-turned flanges enable the channel members to be sonically welded or otherwise secured at 32 and 34 in longitudinal seams along the flanges to securely unite the channel members 26 to the rear surface 33 of the marginal shutter sections 14. The channel members 26 serve as a mounting base for screws which can extend through apertures (not shown) in the marginal sections 14, apertures (not shown) in the webs 42 and into the wall 48.
Alternatively, the shutter 10 can be fastened to the wall with mounting clamps 40, each of which includes a web portion 42 (FIG. 2) and two spaced leg portions 44 and 46 which extend from the web portion 42. The leg portions 44 and 46 extend outwardly from the building wall 48 as shown in FIG. 3. The leg portions are spaced to receive the channel member 26. The channel member 26 is securely retained in the clamp 40 by terminal portions 50 which are hinged to the legs by narrow connecting portions or bands 52 which enable the terminal portions to displace as the channel member 26 is inserted in the clamp. Barb portions 54 extending inwardly from the connecting portions 52 securely anchor the channel in the clamp.
The web portion 42 extends past the leg portions and can be provided with an aperture 56 so that the clamp can be premounted on the building wall 48 with an appropriate fastener 58.
