An elongated, substantially V-shaped roof panel and a roof panel interlocking method using the V-shaped roof panel, having the inclined sides of the V-shaped roof panel provided with elongated stair-stepping reinforcement ribs for purposes of producing a more rigid and stronger roof panel. At the terminating ends of each of the inclined sides there is provided a complementary mechanical lock design that produces a roof panel lock when a first terminating end member, of a plurality of identical roof panels, is mated with an adjoining second terminating end member of a plurality of identical roof panels. Each terminating end mechanical lock design is comprised of various bends in material, shaped such that when adjoining ends of a plurality of identical roof panels are interlocked, the various bends of each lock design are in a closely coupled relationship. The shape of the various bends in each end lock design is attributed with achieving an increasingly tighter bond between roof panels with increasingly higher wind forces experienced. The shape of the various bends used to produce a better lock, coincidentally creates a mini-gutter at the lock which helps prevent water siphoning at the lock and solves a problem which heretofore has not been succesfully solved.
Gutter Facia Design Adapted For Use In Box Beam Applications
A patio cover gutter facia is adapted with two substantially elongated side members which are provided with a complementary mating mechanical design for forming a box beam from interlocking two opposed identical gutter facia. One of the elongated sides of the gutter facia is provided with a screw groove for attaching to a roof panel in a common gutter application. The same side provided with the screw groove is also provided with a first lock member of an interlocked joint. The other one of the elongated sides is provided with a second lock member of an interlock joint. The method of fabricating the gutter facia of the is preferably from a low cost extruded aluminum process which will yield a quality product. In forming a box beam, two identical gutter facia are arranged opposing each other in an inverted interlocking relationship such that, a first lock member and a second lock member of a one gutter facia mates and interlocks respectively with a second lock member and a first lock member of a second gutter facia to form two separate, inverted identical interlocked joints.
Clamping Apparatus Having Snap-Fitting Pivot Structure And Method
A clamp apparatus including a support member and a clamping arm member detachably and hingeally secured to the support member. The support member includes a first mating member of a hinge mechanism and the clamping am member includes a second mating member of the hinge mechanism. The clamp apparatus can not only rotatably and compressively clamp an elongate panel, or sheet object, or other material, but can be assembled by longitudinal engagement of the component members in a flanked, snap-fit manner. To facilitate the flanked, snap-fit formation of the hinge mechanism, the first mating member includes a resilient socket structure having an expandable opening for receiving the second mating member. The second mating member is more rigid than the socket structure, and is shaped having a V-shaped end portion for expanding the expandable opening of the socket structure, and a body portion shaped for detachably fitting within the socket structure in a compressed state for producing tension that effects clamping an object with a clamp end, or provide multiple self-supporting open positions. During assembly, the longitudinal members are positioned longitudinally flanking each other such that the V-shaped end of the longitudinal clamping arm member is in contact with the expandable opening of the longitudinal panel support member.
