BEST MODE FOR CARRYING OUT THE INVENTION
Referring to FIGS. 1-6, there is shown frame member 10 of the present invention. Frame member 10 is elongated and has a predetermined length “L”. Frame member 10 comprises channel-containing section 12 and plate section 14. Plate section 14 is contiguous with and extends from channel-containing section 12. Plate section 14 is rigid. In a preferred embodiment, channel containing section 12 and plate section 14 are integrally formed by an extrusion process. Thus, in a preferred embodiment, frame member 10 is not formed by attaching separate sections together. However, in an alternate embodiment, frame member 10 can be formed by attaching together a separate elongate channel-containing section 12 and separate elongate plate section 14. Referring to FIGS. 1 and 2, channel-containing section 12 comprises rear wall 16, sidewall 18 and sidewall 20. Sidewalls 18 and 20 have outer surfaces 22 and 24, respectively. Sidewalls 18 and 20 are substantially parallel to each other. Channel-containing section 12 further comprises front wall section 26 and front wall section 28. Channel-containing section 12 further comprises longitudinally extending channel 30. Channel 30 comprises section 31 and section 32. Section 32 is relatively wider than section 31. Section 31 defines channel entrance 33. Channel extends for the entire length of frame member 10. Channel 30 is sized to receive spline that secures a screen to frame member 10. Commercially available spline is made out of a variety of resilient materials, e.g. rubber, foam, poly-foam, etc. In a preferred embodiment, the spline should be configured to have a shape that conforms to the shape of channel 30 and a size that allows the spline to be frictionally inserted into channel 30. Each front wall section 26 and 28 is on a corresponding side of channel entrance 33. Front wall sections 26 and 28 are substantially coplanar. Plate section 14 has first surface 36 and opposite second surface 38. Plate section 14 is substantially perpendicular to rear wall 16 of channel-containing section 12. First surface 36 is substantially coplanar with the outer surface 22 of sidewall 18.
Referring to FIGS. 1 and 2, channel 30 has interior wall 40 that extends throughout channel 30. Interior wall 40 comprises portions 42 and 44 that confront channel entrance 33. Channel-containing section 12 further includes a plurality of longitudinally extending nubs 50 and 52 located on portions 42 and 44, respectively, of channel interior wall 40. Thus, nubs 50 are located on one side of channel entrance 33 and nubs 52 are located on the opposite side of channel entrance 33. Nubs 50 and 52 cooperate with the shape of channel 30 to retain the spline within channel 30 and to prevent longitudinal movement of the spline with respect to frame member 10 when the spline is positioned within channel 30. Although two nubs 50 are shown on interior wall portion 42 and two nubs 52 are shown on wall portion 44, it is to be understood that there can be more than or less than two nubs on interior wall portions 42 and 44.
Referring to FIG. 7, channel 30 has a unique shape that facilitates retaining the spline in channel 30. Interior wall 40 further comprises back or rear wall portion 46 and sidewall portions 47 and 48. In accordance with the invention, rear wall portion 46 and sidewall portions 47 and 48 are substantially flat. Interior wall 40 has radiused corners 49.
Referring to FIG. 7, in one embodiment, plate section 14 has a width W1 of about 0.625 inch and channel-containing section 12 has a width W2 of about 0.375 inch. In one embodiment, plate section 14 has a thickness T of about 0.070 inch. It is to be understood that the aforesaid dimensions are just examples and all dimensions of frame member 10 can be varied to suit the particular application.
Referring to FIGS. 2, 3 and 7, plate section 14 has longitudinally extending creases 56 and 58 formed therein to facilitate forming openings through plate section 14. Fastening devices such as nails or screws can then be inserted into these openings so as to allow frame member 10 to be attached to structures. For example, as shown in FIG. 8, frame members 10 are attached to vertical support members 60 and 62. The view in FIG. 8 is a plan view of a portion of screen wall. Thus, the view shows the top ends of vertical support members 60 and 62. Vertical support members 60 and 62 may be columns, wooden posts, metal posts, etc. The reference number 10A refers to the frame member 10 that is attached to vertical support structure 60. Similarly, the reference number 10B refers to the frame member 10 that is attached to vertical support structure 62. Fastening devices 70 are driven through creases 56 of plate sections 14 of frame members 10A and 10B such that frame member 10A is attached to vertical support member 60 and frame member 10B is attached to vertical support member 62. Fastening devices 70 can be nails, screws, etc. In the configuration shown in FIG. 8, frame member 10A is mounted to vertical support member 60 in such a manner that rear wall 16 of channel-containing section 12 and surface 38 of plate section 14 contact the surfaces of the vertical support member 60. Similarly, frame member 10B is mounted to vertical support member 62 in such a manner that rear wall 16 of channel-containing section 12 and surface 38 of plate section 14 contact the surfaces of the vertical support member 62. Referring to FIG. 9, frame members 10A and 10B are attached to vertical support members 60 and 62, respectively, in a different manner. Frame member 10A is attached to vertical support member 60 in such a manner that surface 36 of plate section 14 and outer surface 22 of sidewall 18 contact the surface of vertical support member 60. Similarly, frame member 10B is attached to vertical support member 62 in such a manner that surface 36 of plate section 14 and outer surface 22 of sidewall 18 contact the surface of vertical support member 62. Fastening devices 70 are driven through creases 58 of frame members 10A and 10B in order to attached frame members 10A and 10B to vertical support members 60 and 62, respectively.
Referring to FIG. 7A, there is shown frame member 10 with screen material 78 disposed within channel 30. Only a portion of screen material 78 is shown in this view. Spline 79 is tightly fitted within channel 30 and retains screen material 78 within channel 30. The material from which spline 79 is fabricated allows it to generally conform to the unique shape of channel 30. Nubs 50 and 52 maintain spline 79 in place and prevent spline 79 from becoming dislodged from channel 30. Nubs 50 and 52 and the shape of channel 30 cooperate to prevent spline 79 from rotating and becoming dislodged from channel 30 when a pulling force is applied to screen material 78. Thus, no matter the direction in which screen material 78 is pulled, the spline 79 will not rotate within channel 30
