1. Field of the Invention
The present invention relates generally to structures composed of wooden log elements, and more particularly, it relates to structures composed of simulated log components that visually appear like wooden logs.
2. Description of the Related Art
Log structures such as log homes and cabins are steeped in tradition and have come to symbolize warmth, comfort, and craftsmanship. The rustic appeal and natural beauty of wooden log homes and the time honored heritage and art of constructing quality log structures are only a few reasons why log homes continue to be desired as a popular housing choice. With modern techniques and advanced machinery, the construction of traditional log homes and cabins can range from being elaborate and luxurious dream home to simple do-it-yourself, pre-manufactured log home kits for a starter home.
Society is becoming more and more environmentally conscious and aware of the ecological consequences of excessive consumption of natural resources. As a result, the cutting down of trees, especially old growth trees, to obtain quality lumber to construct log structures are increasingly socially frowned upon and considered environmentally irresponsible.
In addition to the social criticism associated with obtaining the requisite lumber for constructing log structures, traditional log structures are not particularly well suited in certain environments. For example, logs constantly shrink and swell due to changes in moisture content brought on by varying weather patterns. Although log components may be protected and sealed to minimize the effects of moisture change, depending on the environment, seasonal fluctuations in relative humidity may test any finish and/or sealant designed to protect and maintain the log. Over a period of time, high humidity may lead to wood rot and low humidity may lead to cracking of the wood.
High moisture content is also associated with other problems that may compromise the integrity of a log structure. For example, wood destroying fungi and pests such as termites, carpenter ants, and various beetles consume material in the wood cell wall structure, thereby causing decay. Resident insect larvae can live dormant within a log for many years prior to becoming active, and fungi can similarly remain dormant until proper conditions cause the fungi to start or resume its decay activity.
As such, routine and regular maintenance of log structure is essential in order to preserve its natural beauty and to ensure its integrity and lifespan. For example, log homes need to be refinished every couple of years, they need to be regularly inspected for cracks, seals need to be maintained to prevent rot and decay, and the grounds surrounding the log home may need to be treated to discourage pests. Hence, maintenance of log home can be labor intensive and costly.
It is also difficult to incorporate modern building standards and preferences in log homes. Energy efficiency may vary depending on the design and construction method. Windows, doors, and skylights may raise utility bills if sealing is not properly done. Log homes with many corners, joints, and roof angles can consume more energy than log homes with simpler designs. Installation of plumbing, electricity, and heating may pose some challenges, and the insulative properties of log structures are also debatable.
Simulated log construction material is known in the art to overcome the disadvantages generally associated with a log structure. For example, applicant is aware of U.S. Pat. No. 6,851,233 issued on Feb. 8, 2005 to Morgenstern which describes a structural system having a plurality of structural elements including an interior layer, an exterior layer, and an insulating layer between the interior and exterior layer. The exterior layers of the structural elements can be fabricated from cast concrete material and can be provided with simulative exterior surfaces simulating the appearance of structural logs.
Applicant is further aware of U.S. Pat. No. 5,271878 issued on Dec. 21, 1993 to Mizia et al. which describes a simulated half log having a generally semi-cylindrical foam core and a decorative layer on the curved surface. Complementary nailable spines are inset in the flat surface, permitting adjacent half logs to interlock. One spline which extends beyond the edge provides a surface for nailing to a vertical substrate and is concealed when the next adjacent half log is mounted thereover.
Applicant is also aware of U.S. Pat. No. 4,305,238 issued on Dec. 15, 1981 to Harward et al. which describes a simulated log for construction and indoor or outdoor decorative use wherein the log is comprised of at least two semi-circular imitation log siding sections comprising an outer covering with a simulated grain wood containing an insulated filler.
The problem with existing prior art is that none of the simulated logs describe a construction that allows the user to enjoy the natural beauty and comforts of a traditional log home. The prior art describes the use of building materials that simulate the appearance of log structures but fail to describe a structure that provides the warmth, comfort, and craftsmanship associated with tog structures. Owners of log structures desire the rustic appeal and natural beauty of wooden log homes. Wholly simulated log structures fail to connote the sense of nostalgia and fall short of honoring the heritage, history, and culture associated with a genuine log structure. Therefore, an unaddressed need for an improved simulated log structure exists to overcome the inadequacies and deficiencies in the prior art.
The problems and the associated solutions presented in this section could be or could have been pursued, but they are not necessarily approaches that have been previously conceived or pursued. Therefore, unless otherwise indicated, it should not be assumed that any of the approaches presented in this section qualify as prior art merely by virtue of their presence in this section of the application.
It is an object of the present invention to provide a simulated log structure without the maintenance requirements typically associated with a log structure.
It is another object of the present invention to provide a simulated log structure that allows user to enjoy the natural beauty of a real log structure.
It is another object of the present invention to provide a simulated log structure that is durable and easy to construct and incorporates advantages of modern day construction elements.

In a preferred embodiment of the present invention, exterior logs 20 simulate the character, texture, appearance and appeal of wooden logs and is made from composite materials such as but not limited to reinforced precast concrete, resin, composite of fiberglass, polyurethane, polymer and/or polymer concrete. Concrete as a construction material for structures is known to be a relatively good insulator as it absorbs heat during the day and releases it slowly as temperatures cool, providing even indoor temperature. Other composite materials such as but not limited to plastic, wood fiber, resin, composite of fiberglass, polyurethane, polymer and/or polymer concrete composites are contemplated and within the scope of the present invention. Advantageously, exterior logs 20 made from concrete virtually eliminate the typical problems associated with a real wood log structure, such as environmental concerns, instability due to shrinking and swelling, costly and regular maintenance, and susceptibility to the fire, fungi, and wood-boring insects. In addition to the benefit of greater structural stability, concrete eliminates the need to re-stain and reseal wood logs to retain protection from weather and insects. Furthermore, concrete is fire-resistant and resistant to deterioration, insect infestation, and mold growth. However, some of the other materials given as examples above are also fire-resistant and in addition are light-weight materials which simplifies the installation technique and process, as it will be explained later herein, and thus, these materials are more economical to use.

In an embodiment of the invention, semi-cylindrical molds defining central cavity 30 may be made from actual wooden logs to create a mold for exterior logs 20 such that exterior logs 20 substantially look and feel like an actual wooden log, including grain detail and knots. Molds for exterior simulated logs 20 may be made to measure any length and/or diameter. For example, and without intending to be limiting, molds may be made to produce exterior logs 20 measuring eight inches to sixteen inches in diameter and eight feet to twelve feet in length or up to sixty feet.

In a preferred embodiment of the invention wherein each structural element 100 is comprised of a plurality of exterior logs 20 mounted on a first side of structural element 100 and a plurality of interior logs 40 mounted on a second side of structural element 100 opposite the first side as seen in
As seen if FIGS. 3,4, 8 and 9, in an embodiment of the invention at least one angled member 86 may be attached with the channel defined by bottom edge 28 such that a first arm 86a of angled member 86 engages a first side 21 of the channel defined by bottom edge 28 and a second arm 86b of angled member 86 engages flat side 22 and extends upwards from bottom edge 28 inwards the center of exterior log 20. Preferably, angled member 86 is made from a strong and durable material such as metal and may engage the entire length of exterior log 20 or may engage portions of exterior log 20 to reduce weight. Preferably, a plurality of angled members 86 made of iron are attached with exterior log by way of securing members such as screws in spaced apart configuration along the entire length of exterior log 20.

In an alternative embodiment of the invention, a first exterior log 20 may be mounted on a first side of frame 80 by way of fastening means such as nails. Fastening means may be received in the at least one aperture defined by flange 26 so as to secure first exterior log 20 to frame 80 such that flat side 22 of flange 26 engages strapping member 84 in substantially parallel engagement. A second exterior log 20 may be mounted on frame 80 on a first side adjacent a first exterior simulated log 20 in a similar fashion such that flange 26 of first exterior log 20 is received within channel 28 of second exterior log 20. By mounting subsequent exterior logs 20 in such a manner wherein flange 26 of a previously mounted exterior log 20 is received within channel 28 of a subsequently mounted exterior log 20, a plurality of exterior logs 20 may be mounted adjacent to one another in an abutting or overlapping function onto frame 80 to simulate the appearance of a wooden structural element 100 that may be used to construct, for example, a log cabin that appears to be a wooden log cabin on the exterior.

In another alternative embodiment of the invention, edge 26, 28 of exterior simulated logs 20 may each be comprised of a fastening portion in the form of flange. Preferably, both flanges are integrally formed with edge 26, 28, respectively, and define at least one aperture wherein such at least one aperture is adapted to receive the fastening means for securing exterior log 20 onto frame 80. A filler such as weather resistant concrete fillers or sealers known in the art may be used to cover the visible heads of the fastening means for aesthetic purposes.
a-e depict a sectional, front-perspective, back-perspective, front and side view, respectively, of a corner member 146. Again, as mentioned earlier, the inner end (i.e, the end facing the structure to which is attached) of the corner member 146, will typically have a portion 146e (substantially half or other than half, depending primarily on the look sought) that is configured such that it has a forty-five (45) degrees angle with the longitudinal axis of the corner member 146. Again, the other portion 146f is straight, meaning that it is substantially at ninety degrees angle with the longitudinal axis of the corner member 146. The straight portion 146f allows for a closer fit and stronger attachment of the corner member 146 to a typical structure which will have generally a flat exterior surface. Once again, the forty-five degree portion 146e of two opposite corner members allows for the formation of a ninety degree angle between the respective corner members, which is desirable when working with a typical structure having walls joining perpendicularly. It should be apparent that the angle of the 146e portion may be adjusted if needed, such as when the structure has walls which do joint each other at a ninety degree angle.
a depicts a partial sectional view of a structure using exterior simulated logs 152.
Again, a quarter (half of a half) log 158 is typically needed, as described earlier, to start from the bottom on one of the two walls of structure, which are joining each other at a ninety degree angle, in order to obtain the desired staggered log appearance. Thus, for example, when the simulated logs are mounted to the sides of a structure, a quarter log is mounted on the bottom row, giving the outside appearance of a half log. Whereas, in the front and back of the structure, the half log is used, including as the bottom row, visibly appearing as though it were a whole log. Thus, the staggering of the alternating rows, or ‘rounds’ as they are referred to in log house terminology, is achieved. As shown, the quarter log 158 may also have a flange 1526, to be used during installation as described above, and it is also hollow (see its central cavity 1530q in
From the foregoing description, it may be seen that the device formed in accordance with the present invention incorporates many novel features and offers significant advantages over those currently available.
