Definitions

  • the present invention relates to a locking beam assembly for modular construction and, in particular, to a locking beam that can be prefabricated based on the design specifications of a particular construction project.
  • corrugated toothed web strips with penetration stoppers for joining timbers with other timbers or non-wooden materials for the formation of beams, walls or other construction support designs. See U.S. Pat. No. 4,337,287.
  • the web strips with penetration stoppers are generally formed from preformed sheet metal materials, but the overall structure of the support element is generally wood or a wood composite material.
  • the locking beam assembly (100) of the present invention comprises opposing locking beams (10a, 10b), comprising an first locking beam (10a) and a second locking beam (10b), and a flexible support panel (17) disposed between the opposing locking beams (10a, 10b).
  • the locking beams (10a, 10b) and flexible support panel (17) are prefabricated in various dimensions to accommodate different construction projects.
  • the locking beams (10a, 10b) and flexible support panel (17) are preferably sold or shipped to a construction site where they can be assembled to meet the project specifications.
  • Each locking beam (10a or 10b) will comprise a load support surface (11) and at least one preformed flexible support panel engaging surface (37), which can be opposite the load support surface (11) in the case of a single flexible support panel engaging surface (37), or offset from the load support surface (11) at an angle dependent on the number of flexible support panel engaging surfaces (37) per locking beam.
  • the locking beams (10a, 10b) can further comprise a lead end (35) and a tail end (36) at the longitudinal ends of the locking beams (10a, 10b).
  • the flexible support panel engaging surface (37) can comprise means for engaging the flexible support panel (17).
  • the means for engaging the flexible support panel (17) can comprise retaining means (12a, 12b).
  • Embodiments of the retaining means (12a, 12b) can be grooves formed into the flexible support panel engaging surface (37) or projections extending upwardly from the flexible support panel engaging surface (37).
  • the means for engaging the flexible support panel (17) can comprise a guide projection (13).
  • the guide projection (13) extends upwardly from the flexible support panel engaging surface (37) of the locking beam (10a, 10b) and is preferably, but not necessarily, centrally located on the flexible support panel engaging surface (37) of the locking beam (10a, 10b).
  • the retaining means (12a, 12b) In an embodiment of the present invention that comprises both retaining means (12a, 12b) and a guide projection (13), the retaining means (12a, 12b) generally run parallel to the guide projection (13).
  • a flexible support panel (17) is designed to interconnect with the opposing locking beams (10a, 10b).
  • the flexible support panel (17) is designed to interlock with the first and second locking beams (10a, 10b). More particularly, the flexible support panel (17) possess foldable points or axes (18a, 18b, 18c, etc..) that allow the flexible support panel (17) to be shaped or bent at the construction site and easily engaged with the opposing locking beams (10a, 10b).
  • the fold points or axes (18a, 18b, 18c, etc..) also define multiple segments of the flexible support panel (17). Variations in the flexible support panel segments are prepared that can correspond with either retaining means (12a, 12b) or a guide projection (13). These segments are referred to herein as the alternating flexible support segment (171a), and the longitudinal flexible support segment (171b).
  • the alternating flexible support panel (171a) can comprise an opening (32) formed on the edge of the alternating flexible support segment (171a), i.e., the flexible support panel segment can be designed to correspond with the shape of the guide projection (13) and possess an opening (32a, 32b, etc.).
  • the longitudinal flexible support panel segment (171b) can be designed to correspond and/or interact with the shape of the retaining means (12a, 12b), and can be designed to contain a groove (31) which corresponds with the internal side of the retaining means (12a or 12b).
  • the flexible support panel (17) can optionally be designed to possess a locking collar (16) which projects from the opening (32) of the flexible support panel (17) and engages a guide projection (13).
  • the locking collar (16) can be formed on either side of the opening (32) on the flexible support panel (17), and is designed to maintain the flexible support panel (17) locked in place within the locking beam (10a, 10b).
  • External framing panels (34) can be added to the locking beam assembly (100).
  • the external framing panels (34) can be inserted into external grooves (19a, 19b) that run longitudinally along the length of the locking beams (10a, 10b) and can be formed in the retaining means (12a, 12b) of the locking beams (10a, 10b).
  • the locking beams (10a, 10b) can comprise more than one external groove (19) depending on the final product design.
  • the external grooves (19) can be positioned intermittently along the locking beam to allow for external framing panels (34) that do not run the entire length of the locking beam (10a, 10b).
  • external framing panels (34) can be attached to the outside surface of the locking beam (10a, 10b), such as the retaining means (12a, 12b) by conventionally known means, such as adhesives, screws or nails.
  • the locking beam assembly (100) can also include a locking element or means (20) which is designed to lock the flexible support panel (17) in position within the locking beams (10a, 10b) and create a secure and stable locking beam assembly (100).
  • the locking element (20) may comprise a locking plate (38) and a tensioning element (21) that extends thought the locking beam (10a, 10b) or flexible support panel (17), and though an opening (22) on the locking plate (38), and wherein the tensioning element (21) is fastened to a locking mechanism (23) exterior to the locking plate (38).
  • the tensioning element (21) can be a cable, metals or other flexible materials, a metal bar with threaded ends, fiberglass, a threaded bar, or other equivalent materials that can be used to increase tension in the locking beam (10a, 10b).
  • the locking element (20) employed in embodiments of the present invention may include a locking beam assembly (100) comprising multiple locking beam assemblies (100a, 100b, 100c, etc..) in a parallel arrangement to create locking beams of a desired length.
  • the locking beam assembly (100) of the present invention can be of any overall height or width, consistent with the overall description of the present invention. More specifically, the locking beam assembly (100) can be as small as a few centimeters in height or as high as several meters, depending on the type of construction design required. This can be evident where the construction material necessary is an I-beam that only needs to be measured in centimeters in height, or a wall for a building that may need to be several meters in height.
  • the length of the locking beam assembly (100) is also dependent on the particular construction design necessary, and the length can be measured in a few centimeters or in several meters.
  • the locking beam of the present invention can be manufactured to suit any desired construction project and/or shape of the desired final product.
  • the locking beams can be linear, arched, rounded, oval, rectangular, or any desired shape required by the construction project. Further, the locking beams can be assembled with various combinations of flexible support panel engaging surfaces, external grooves, flexible support panels, and/or exterior framing panels to produce the desired the final structure.
  • the locking beam assembly (200) can be prepared from an extrusion process in which the entire locking beam assembly, i.e., support panel, and first and second beams are extruded in a one step process.
  • the locking beam assembly may also include a tensioning element that can be co-extruded in a one step process.

Description

LOCKING BEAM ASSEMBLY
FIELD OF THE INVENTION
The present invention relates to a locking beam assembly for modular construction and, in particular, to a locking beam that can be prefabricated based on the design specifications of a particular construction project.
BACKGROUND OF THE INVENTION
Various methods are known to create beams or walls for construction projects. One such method is sheet metal wall construction, in which a header is formed from a pair of sheet metal beams that are bolted together. An example of this construction is disclosed in U.S. Pat. No. 6,131,362. Other sheet metal header beam construction materials are described in U.S. Published Application No. 2008/0196332.
Also known in the art are corrugated toothed web strips with penetration stoppers for joining timbers with other timbers or non-wooden materials for the formation of beams, walls or other construction support designs. See U.S. Pat. No. 4,337,287. The web strips with penetration stoppers are generally formed from preformed sheet metal materials, but the overall structure of the support element is generally wood or a wood composite material.
An additional construction method is disclosed in U.S. Published Application No. 2007/0277476, which discloses a modular wall system for constructing temporary buildings, such as warehouses, using stacked elongated panels.
There is a need for a locking beam assembly that can be constructed fast and easy from preformed materials, which possesses greater load bearing capacity and greater design reproducibility than the known prior art construction materials. Additionally there is a need for a cheaper and more consistent beam construction material than is currently available. The principal object of the present invention is to fill these needs.
SUMMARY OF THE INVENTION
In an embodiment of the present invention, the locking beam assembly (100) of the present invention comprises opposing locking beams (10a, 10b), comprising an first locking beam (10a) and a second locking beam (10b), and a flexible support panel (17) disposed between the opposing locking beams (10a, 10b). The locking beams (10a, 10b) and flexible support panel (17) are prefabricated in various dimensions to accommodate different construction projects. The locking beams (10a, 10b) and flexible support panel (17) are preferably sold or shipped to a construction site where they can be assembled to meet the project specifications.
Each locking beam (10a or 10b) will comprise a load support surface (11) and at least one preformed flexible support panel engaging surface (37), which can be opposite the load support surface (11) in the case of a single flexible support panel engaging surface (37), or offset from the load support surface (11) at an angle dependent on the number of flexible support panel engaging surfaces (37) per locking beam. The locking beams (10a, 10b) can further comprise a lead end (35) and a tail end (36) at the longitudinal ends of the locking beams (10a, 10b).
In an embodiment of the present invention comprising the locking beam (10a, 10b), and the flexible support panel (17), the flexible support panel engaging surface (37) can comprise means for engaging the flexible support panel (17). The means for engaging the flexible support panel (17) can comprise retaining means (12a, 12b). Embodiments of the retaining means (12a, 12b) can be grooves formed into the flexible support panel engaging surface (37) or projections extending upwardly from the flexible support panel engaging surface (37).
In an alternate embodiment of the present invention comprising the locking beam (10a, 10b), and the flexible support panel (17), the means for engaging the flexible support panel (17) can comprise a guide projection (13). The guide projection (13) extends upwardly from the flexible support panel engaging surface (37) of the locking beam (10a, 10b) and is preferably, but not necessarily, centrally located on the flexible support panel engaging surface (37) of the locking beam (10a, 10b).
In an embodiment of the present invention that comprises both retaining means (12a, 12b) and a guide projection (13), the retaining means (12a, 12b) generally run parallel to the guide projection (13).
A flexible support panel (17) is designed to interconnect with the opposing locking beams (10a, 10b). The flexible support panel (17) is designed to interlock with the first and second locking beams (10a, 10b). More particularly, the flexible support panel (17) possess foldable points or axes (18a, 18b, 18c, etc..) that allow the flexible support panel (17) to be shaped or bent at the construction site and easily engaged with the opposing locking beams (10a, 10b). The fold points or axes (18a, 18b, 18c, etc..) also define multiple segments of the flexible support panel (17). Variations in the flexible support panel segments are prepared that can correspond with either retaining means (12a, 12b) or a guide projection (13). These segments are referred to herein as the alternating flexible support segment (171a), and the longitudinal flexible support segment (171b).
In embodiments of the present invention that posses a guide projection (13), the alternating flexible support panel (171a) can comprise an opening (32) formed on the edge of the alternating flexible support segment (171a), i.e., the flexible support panel segment can be designed to correspond with the shape of the guide projection (13) and possess an opening (32a, 32b, etc.). The longitudinal flexible support panel segment (171b) can be designed to correspond and/or interact with the shape of the retaining means (12a, 12b), and can be designed to contain a groove (31) which corresponds with the internal side of the retaining means (12a or 12b).
In embodiments of the present invention that posses a guide projection (13), the flexible support panel (17) can optionally be designed to possess a locking collar (16) which projects from the opening (32) of the flexible support panel (17) and engages a guide projection (13). The locking collar (16) can be formed on either side of the opening (32) on the flexible support panel (17), and is designed to maintain the flexible support panel (17) locked in place within the locking beam (10a, 10b).
External framing panels (34) can be added to the locking beam assembly (100). The external framing panels (34) can be inserted into external grooves (19a, 19b) that run longitudinally along the length of the locking beams (10a, 10b) and can be formed in the retaining means (12a, 12b) of the locking beams (10a, 10b). The locking beams (10a, 10b) can comprise more than one external groove (19) depending on the final product design. Additionally, the external grooves (19) can be positioned intermittently along the locking beam to allow for external framing panels (34) that do not run the entire length of the locking beam (10a, 10b). Alternatively, external framing panels (34) can be attached to the outside surface of the locking beam (10a, 10b), such as the retaining means (12a, 12b) by conventionally known means, such as adhesives, screws or nails.
The locking beam assembly (100) can also include a locking element or means (20) which is designed to lock the flexible support panel (17) in position within the locking beams (10a, 10b) and create a secure and stable locking beam assembly (100). The locking element (20) may comprise a locking plate (38) and a tensioning element (21) that extends thought the locking beam (10a, 10b) or flexible support panel (17), and though an opening (22) on the locking plate (38), and wherein the tensioning element (21) is fastened to a locking mechanism (23) exterior to the locking plate (38). The tensioning element (21) can be a cable, metals or other flexible materials, a metal bar with threaded ends, fiberglass, a threaded bar, or other equivalent materials that can be used to increase tension in the locking beam (10a, 10b).
The locking element (20) employed in embodiments of the present invention may include a locking beam assembly (100) comprising multiple locking beam assemblies (100a, 100b, 100c, etc..) in a parallel arrangement to create locking beams of a desired length.
The locking beam assembly (100) of the present invention can be of any overall height or width, consistent with the overall description of the present invention. More specifically, the locking beam assembly (100) can be as small as a few centimeters in height or as high as several meters, depending on the type of construction design required. This can be evident where the construction material necessary is an I-beam that only needs to be measured in centimeters in height, or a wall for a building that may need to be several meters in height.
Additionally, the length of the locking beam assembly (100) is also dependent on the particular construction design necessary, and the length can be measured in a few centimeters or in several meters.
The locking beam of the present invention can be manufactured to suit any desired construction project and/or shape of the desired final product. The locking beams can be linear, arched, rounded, oval, rectangular, or any desired shape required by the construction project. Further, the locking beams can be assembled with various combinations of flexible support panel engaging surfaces, external grooves, flexible support panels, and/or exterior framing panels to produce the desired the final structure.
Another embodiment of the present invention of the locking beam assembly (200) can be prepared from an extrusion process in which the entire locking beam assembly, i.e., support panel, and first and second beams are extruded in a one step process. In this embodiment of the present invention the locking beam assembly may also include a tensioning element that can be co-extruded in a one step process.
The locking beam of the present invention may be constructed of any suitable material or combination of materials, such as wood, metal, fiberglass, plastics, wood/plastic composite, or combinations of the foregoing. Additional objects, advantages and features of the invention will become apparent from the description set forth below, from the drawings, and from the principles that are embodied in the specific structures that are illustrated and described.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT
The present invention will be described by references to the figures, which depict embodiments of the present invention. The following description of the figures is not intended to limit the scope of the invention to any particular shape, design or dimensions. Alternate shapes and structures are provided in the figures and more will be readily apparent to individuals skilled in the art based upon the following description.
FIG. 1 is a view of an embodiment of a locking beam of the present invention. The locking beam assembly (100) of the present invention includes opposing locking beams (10a, 10b), comprising an first locking beam (10a), and a second locking beam (10b), and a preformed flexible support panel (17) disposed between the opposing locking beams (10a, 10b). The locking beams (10a, 10b) of the present invention can be any shape commensurate with the desired construction project, possible shapes include, but are not limited to rectangular, pentagonal, hexagonal, trapezoidal, arched, or circular. As shown in FIG. 1, the locking beam (10a, 10b) possesses a load support surface (11), and a flexible support panel engaging surface (37) located opposite the load support surface (11). The locking beam may comprise more than one flexible support panel engaging surface (37). Where more than one flexible support panel engaging surface (37) is present per locking beam (10a, 10b), the flexible support panel engaging surfaces (37) are offset from the position opposite the load support surface (11).
The locking beams (10a, 10b) further comprise an lead end (35) and an tail end (36) at the longitudinal ends of the locking beams (10a, 10b). The flexible support panel engaging surface (37) of the locking beam (10a, 10b) further can optionally comprise retaining means (12a, 12b), and/or a guide projection (13) running longitudinally through the flexible support panel engaging surface (37) of the locking beams (10a, 10b). The retaining means (12a, 12b) and the guide projection (13) form two channels (14a, 14b) that run longitudinally through the flexible support panel engaging surface (37) of the locking beams (10a, 10b). Alternate embodiments of the present invention can be prepared without a guide projection (13) or with more than one guide projection (13) running longitudinally through the flexible support panel engaging surface (37) of the locking beam (10a, 10b). In embodiments of the present invention without a guide projection (13), the flexible support panel engaging surface will only possess one channel (14), while embodiments with more than one guide projection (13a, 13b) will possess three or more channels (14a, 14b, 14c, etc...).
In the embodiment shown in FIGS. 1-8, the retaining means (12a, 12b) possess an external side and an internal side. The internal side of the retaining means (12a, 12b) can be formed to possess flanges (15a, 15b) that give a predetermined shape to the channels (14a, 14b). Preferably the flanges (15a, 15b) are rounded at the top end of the retaining means (12a, 12b) and curve downward approximately midway into the channel (14a, 14b), ending in a tail end that is perpendicular to the bottom of the channels (14a, 14b) in flexible support panel engaging surface (37) of the locking beam (10a or 10b). The bottom portion of the channels (14a, 14b) is generally flat and runs transversely from the internal side of the retaining means (12a, 12b) to the guide projection (13). Alternate embodiments of the channels (14a, 14b) will be readily apparent to persons skilled in the art. Alternate embodiments of the channels (14a, 14b) can be prepared by changing the shape of, and/or removing, the retaining means (12a, 12b), the flexible support panel engaging surface (37), and/or the guide projection (13).
The locking beam (10a, 10b) can also be constructed to contain openings (39) that run longitudinally through the locking beam (10a, 10b), and which allow for the passage of electrical wires, piping, conduits, duct work, or other construction material that may be employed in the final construction project. As discussed above, the locking beams (10a, 10b) are prefabricated based on the desired needs of a particular construction project, and the locking beams (10a, 10b) can contain a plurality of these longitudinal openings (39a, 39b, 39c, etc .), in accordance with the particular construction project to be completed. The longitudinal openings (39) can be of any shape and size. Embodiments of the longitudinal opening (39) of the present invention can be seen in FIGs. 2-5b. The guide projection (13), as shown in FIG. 2 is formed in the shape of two opposing flanges, which form the partial tube formation shown in FIG. 2. The guide projection (13) can be any shape commensurate with the present invention, such as but not limited to, circular, tetrahedral, square, pentagonal, or octagonal. Additionally, the flexible support panel engaging surface can contain more than one guide projection (13).
The overall formation of the flexible support panel engaging surface (37) allows the flexible support panel (17), which is designed to match the shape of the channels (14a, 14b), to lock in place in a modified tongue and groove formation. A head-on view of an embodiment of a locking beam (10a, 10b) of the present invention can be seen in FIG. 8a (without the flexible support panel (17)), and side views of an embodiment of a locking beam (10a, 10b) of the present invention (with the flexible support panel (17)) can be seen in FIGs. 1, 2, 4, 6 and 7.
Embodiments of the flexible support panel engaging surface (37) can include securing means, such as resilient tabs or teeth that allow the flexible support panel (17) to slide in one direction, but will prevent its withdrawal in the reverse direction. The teeth or tabs can engage the corresponding projections or indents, which can be formed in the corresponding flexible support panel (17).
The locking beam (10a, 10b) can be made of any suitable construction material, such as wood, plastics, concrete, steel, fiberglass, aluminum, titanium, etc... Preferred materials are a mixture or composite of 50-90% wood and 10-50% plastic. A most preferred material is a mixture of 70% wood and 30% plastic, known commercially as WPC. The flexible support panel (17) is preferably constructed from corrugated sheet metal, however, other suitable construction materials, such as plastics, or composite materials, may be employed.
The preformed flexible support panel (17) is designed to interconnect with the opposing locking beams (10a, 10b). More particularly, the flexible support panel (17) is designed to fold vertically along fold points or axes (18a, 18b, 18c, etc ..) that allow the flexible support panel (17) to be shaped so that it can extend generally longitudinally along the length of the locking beams (10a, 10b) and transversally across the two channels (14a, 14b) and around the guide projection (13). The flanges (15a, 15b) on the retaining means (12a, 12b), as well as the guide projection (13) allow for a modified tongue and groove arrangement between the locking beam (10a, 10b) and the flexible support panel (17). The arrangement of the flexible support panel (17) between the first and second locking beams (10a, 10b) allows for an improved redistribution of load and improved strengthening of the locking beam assembly (100) in comparison to known prior art beam construction methods.
The flexible support panel (17) is further constructed so that the lower horizontal edge (29) and the upper horizontal edge (30) of the flexible support panel (17) contain grooves or projections (3 la, 3 lb, etc...) and/or openings (32a, 32b, etc...) that correspond with the channels (14a, 14b) and the guide projection (13) of the flexible support panel engaging surface (37) of the locking beam (10a, 10b). More specifically, the flexible support panel (17) can be segmented into alternating flexible support segments (171a) comprising openings (32) corresponding with the guide projection (13), and longitudinal flexible support segments (171b) comprising grooves or projections (31) corresponding with the inner side of the retaining means (12a, 12b).
The flexible support panel (17) can optionally be constructed to possess a locking collar (16) which projects from the opening (32) of the flexible support panel (17) and engages the guide projection (13). The locking collar (16) shown in FIG. 7 engages the guide projection (13) at opening (32) of the alternating flexible support segments (171ai, 171a2). The locking collar
(16) of the present invention can be a directional clamp that is capable of shifting and locking in place once the flexible support panel (17) is placed in a final position within the locking beam (10a, 10b).
In a embodiment of the present invention, shown in FIGs. 1-7 and 9-11, the flexible support panel (17) is prefabricated so that it can be bent or folded so that a plurality of segments are formed in each flexible support panel (17). The folded segments, as shown in the embodiment of the present invention in FIGs. 1-7 and 9-11 comprise a first alternating segment (171ai), a first longitudinal segment (171bi), a second alternating segment (171a2), a second longitudinal segment (171b2), and a third alternating segment (171a3). More specifically, the flexible support panel (17) is inserted into first and second locking beams (10a, 10b) in a longitudinal manner so that the first alternating segment (171ai) of the flexible support panel
(17) runs transversely perpendicular to the longitudinal axis of the locking beam (10b), and intersects with the guide projection (13) and a flange (15a) on the inner side of one of the retaining means (12a). The next portion of the flexible support panel (17) is formed at the first fold (18a), and is the first longitudinal segment (171bi), which runs longitudinally along the inner portion of the retaining means (12a), and possesses a groove (31a) along the lower horizontal edge (29) that surrounds the flange (15a) on the inner side of the retaining means (12a). The third section of the flexible support panel (17), the second alternating segment (171a2) is formed at the second fold (18b) of the flexible support panel (17). The second alternating segment (171a2) runs generally transversally across the locking beam (10a) from the inner portion of the retaining means (12a) to the inner portion of the retaining means (12b). The second alternating segment (171a2) possesses an opening (32) and a locking collar (16) formed in the lower horizontal edge (29) of the flexible support panel (17) allowing the second alternating segment (171a2) to surround the guide projection (13) of the locking beam (10b). Preferred embodiments of the flexible support panel (17) can be seen in FIGs. 9-11. The interconnection of the locking beam (10b) and the flexible support panel (17) can be seen in FIGs. 1, 2, 4, 6 and 7.
The alternating segments (171a) generally run perpendicular to the longitudinal axis of the locking beams (10a, 10b). However, the alternating segments (171a) can be bent along the fold points (18) in such a manner that the angle at which the alternating segments (171a) bisect the locking beam can be greater than 90°, and up to 135°, depending on the optimal load bearing capacity of the final locking beam assembly (100).
The next section of the flexible support panel (17) is formed at the third fold (18c) and forms the second longitudinal segment (171b2), which runs longitudinally along the inner portion of the retaining means (12b), and possesses a groove (31b) along the lower horizontal edge (29) that corresponds with the flange (15b) on the inner side of the retaining means (12b). At the fourth fold (18d) is formed the third alternating segment (171a3) of the flexible support panel (17), which runs transversely perpendicular to the longitudinal axis of the locking beam (10b) from a flange (15b) on the inner portion of the retaining means (12b) to the guide projection (13). An identical arrangement of grooves, openings, folds and flexible support panel segments (171a, 171b) on the upper horizontal edge (30) of the flexible support panel (17) allow the upper horizontal edge (30) of the flexible support panel (17) to lock into a modified tongue and groove arrangement with the opposing locking beam (10a).
An alternate embodiment of the flexible support panel (17), which is shown in FIGs. 12, 14, 15 and 16, the flexible support panel (17) can possess three fold points (18a, 18b, 18c) and four segments. As can be seen in FIGs. 14 and 15, the flexible support panel is designed to have a first longitudinal segment (171bi), a first alternating segment (171ai), a second longitudinal segment (171b2), and a second alternating segment (171a2). The flexible support panel (17) disclosed above, will also contain an arrangement of grooves (31a, 31b, etc ..) and openings (32a, 32b, etc ..) that correspond with the channels (14a, 14b) and guide projection (13) of the locking beams (10a, 10b). Alternative configurations of the flexible support panel (17) can be prepared to provide increased strength and/or stability to the locking beam assembly (100). It is also possible to use shorter and/or fewer flexible support panels (17a, 17b, etc ..) if a reduced weight of the overall locking beam assembly (100) is desired. Additionally, alternative arrangements of flexible support panel segments, either in number or order will be readily apparent to individuals skilled in the art based upon the present descriptions.
Alternate embodiments of the present invention can also include locking beams (10a or 10b) that employ more than one flexible support panel engaging surface (37a, 37b, etc..) on each locking beam (10a or 10b). When more than one flexible support panel engaging surface (37a, 37b, etc..) is present on an individual locking beam (10a or 10b), the flexible support panel engaging surfaces (37a, 37b) are offset form the load bearing surface (11).
The locking beam assembly (100) can further contain open areas, i.e., the hollow sections of the locking beam assembly running from the flexible support panel engaging surface (37) of the first locking beam (10b) to the flexible support panel engaging surface (37) of the second locking beam (10a), which allows room for auxiliary material, such as heating insulation, sound proofing insulation, and additional strengthening materials to aid in the overall load bearing capacity of the locking beam assembly (100).
Spacers (33) can be positioned internally within the locking beams (10a, 10b). The spacers (33) can be positioned within the locking beams (10a, 10b) to provide added strength to the locking and positioning of the flexible support panel (17) within the locking beams (10a, 10b). The spacers (33) can also reduce the necessary length of the flexible support panels (17) when there is less load bearing capacity necessary for the desired construction project. The spacers (33) are designed to match the shape or contours of the flexible support panel engaging surface (37) of the locking beams (10a, 10b), either internally between adjacent alternating segments (171a) of the flexible support panel (17), i.e., between, the first alternating segment (171ai) and the second alternating segment (171a2); or between adjacent flexible support panels (17a, 17b, etc...) running longitudinally through the locking beams (10a, 10b). The spacers (33) are generally formed of solid plastic material, but can be prepared from any suitable construction material, such as wood, or wood composite materials comprising wood and plastic materials, metals, or composite materials. The spacers (33) may be further locked in place through the use of securing means, such as a screw, construction adhesive or glue, a nail, a nut and bolt, combinations thereof, or other securing means that will be readily apparent to the skilled artisan. Spacers (33) in accordance with the present invention can be seen in FIGs. 13, 14, 15 and 16. In particular, the spacer (33) can be seen located between the first alternating segment (171ai) and the second alternating segment (171a2) in FIG. 16.
Securing means (42) such as screws, bolts, nails, adhesives, combinations thereof, or other securing means readily apparent to the skilled artisan can be employed to lock the flexible support panel (17) or spacer (33) in place within the locking beam (10a, 10b). Embodiments of the securing means (42) of the present invention are shown in FIGs. 14 and 15.
Alternate embodiments of the present invention can employ means to secure the external framing panel (34), spacers (33) or flexible support panels (17) within the locking beam. One such method is to weld the external framing panel (34), spacer (33) or flexible support panel (17) within the locking beam (10a, 10b) in a locked position after construction of the locking beam assembly (100). Other methods for securing the external framing panel include, but are not limited to, screws, bolts, nails, adhesives, combinations thereof, or other securing means readily apparent to the skilled artisan.
The present invention can be prepared with any combination and number of flexible support panels (17a, 17b, 17c, etc ..) and spacers (33a, 33b, 33c, etc ..) located internally within the locking beam assembly (100) as is necessary for support, design and size purposes.
Combinations of flexible support panels (17a, 17b, 17c, etc...) can be combined based on the desired length of the locking beam (10a, 10b). For example, the flexible support panel (17) can be prepared in 2.5 meter lengths, and two can be combined to create a 5 meter panel or four to create a 10 meter panel. As demonstrated above, flexible support panels (17) can be added and combined as necessary.
External framing panels (34) can be added to the locking beam assembly (100). The external framing panels can be added to the external side of the retaining means (12a, 12b) of the locking beams (10a, 10b). In an embodiment of the present invention, the external framing panels (34) can be inserted into external grooves (19) that are formed in the retaining means (12a, 12b) of the locking beams (10a, 10b). The external grooves (19) preferably run longitudinally along the length of the locking beams (10a, 10b). Preferably the external grooves (19a, 19b) are square grooves designed to receive an external framing panel (34), which can be a flat piece of wood paneling, sheet metal, sheetrock or other suitable construction material. In an alternate embodiment the external grooves (19a, 19b) can be formed with flanges and/or shaped grooves corresponding with a matched piece of external framing panel (34). Use of the external framing panel (34) in accordance with the present invention can be seen in FIGs. 12 and 14-16.
In a still further embodiment, the external framing panels (34) can be attached to an external surface of the locking beams (10a, 10b) by any means commonly used in the industry. The external framing panels (34) can be secured to the locking beam assembly (100) by the use of screws, bolts, nails, adhesives, combinations thereof, or other securing means readily apparent to the skilled artisan.
The locking beam assembly (100) can also include a locking element (20) which is designed to lock the flexible support panel (17) in position within the locking beams (10a, 10b). The locking element (20) secures the locking beam (10a, 10b) by use of tensioning element (21) that extend thought the locking beam (10a, 10b), and though an opening (22) in a locking plate (38). The tensioning element (21) is fastened to a locking mechanism (23) exterior to the locking plate (38). In a preferred embodiment the tensioning element (21) extends thought the guide projection (13) of the locking beam (10a, 10b). Preferred tensioning element (21) include, but are not limited to, cables, metals or other flexible material, fiberglass, metal bars with threaded ends, threaded bars, or other suitable tensioning means, which will be readily apparent to the skilled artisans.
In a preferred embodiment, the locking element (20) will surround the open lead end (35) of the locking beam (10a, 10b) and extend partially longitudinally across the open lead end (35) of the locking beam (10a, 10b). The locking plate (38) will also possess an opening (22) that is preferably circular to allow for a locking mechanism (23) to be inserted through the opening (22) and connect with a tensioning element (21) that runs longitudinally through the guide projection (13) of the locking beam (10a, 10b). The tensioning element (21) can be tightened with the locking mechanism (23) to increase the tension between the flexible support panels (17), spacers (33) and the locking beams (10a, 10b). Equivalent locking plates (38a, 38b), openings (22a, 22b), tensioning element (21a, 21b) and locking mechanisms (23a, 23b) can be employed in the upper and lower locking beams (10a, 10b). The locking plate (38), opening (22), tensioning element (21) and locking mechanism (23) of the present invention can be seen in FIGs. 12-16. Although the figures show the tensioning element (21) running through an opening in the guide projection (13), the tensioning element (21) may also run through alternative openings in the locking beam (10a, 10b), such as longitudinal opening (39), or openings in the flexible support panel (17). More than one tensioning element (21) may be employed per locking element (20).
Alternate embodiments can employ more than one locking element (20a, 20b, 20c, etc .), tensioning element (21a, 21b, 21c, etc.), locking plates (38a, 38b, 38c, etc.), and locking mechanisms (23a, 23b, 23c) per locking beam (10a, 10b) to provide added strength to the locking beam (100).
Additionally, the locking beams (10a, 10b) can be constructed so that either the lead end (35) or the tail end (36) of the locking beam (10a, 10b) is closed to eliminate movement of the flexible support panel (17) or spacer (33) within the channels (14a, 14b) of the flexible support panel engaging surface (37) past a closed end (35 a or 36a) of the alternate version of the locking beams (10a, 10b).
In an alternate embodiment of the present invention shown in FIG. 18, the locking beam assembly (10) can be prepared as a single unit that contains a tensioning element (21) running longitudinally through the base of the locking beam (10). The tensioning element (21) can be secured to a locking mechanism (23) or locking element (20) to add stability and strength to the locking beam (100a or 10b). The locking beam (10) depicted in FIG. 18, can be prepared from an extrusion process wherein the locking beam (10) and the tensioning element (21) are prepared in a single co-extrusion process. An embodiment of the co-extrusion process can be prepared wherein the locking beam (10) is prepared from a plastic material and the tensioning element (21) is prepared from a metal composition, such as rebar. Alternate compositions for the locking beam (10) and the tensioning element (21) will be readily apparent to persons skilled in the art based on the present disclosure.
FIG. 19 shows an alternate embodiment of the present invention, wherein the locking beam assembly (200) is formed from a single or unitary piece, along with a tensioning element (21). Materials that may be employed in the construction of this embodiment of the locking beam assembly include, but are not limited to, wood, metal, plastics, fiberglass, wood/plastic composite, or combinations of the foregoing. FIGs. 20 and 21 depict an embodiment of the present invention comprising two locking beam assemblies (100a, 100b) running generally parallel to each other. The locking beams (10a, 10b) of the embodiment shown in FIGs. 20 and 21, have been prefabricated to possess external channels (19) in the locking beams (10a, 10b) that are designed to accommodate external framing panels (34) extending generally perpendicular, or in an arched configuration in relation to the vertical height of the flexible support panels (17). Through the use of matching but opposing locking beams (10a, 10b), the parallel locking beam assemblies (100a, 100b) can be joined together by the interconnection of the external framing panels (34) at the external channels (19) of the neighboring locking beam assembly (100a or 100b). In the embodiment of the present invention shown in FIGs. 20 and 21, the external channels (19) and the corresponding external framing panels (34) are angled and arched to give an arched formation to the final structure.
Alternate embodiments in accordance with the present invention are possible where the external channels (19) and external framing panels (34) are prefabricated so that the external channels (19) are perpendicular to the vertical height of the flexible support panels (17), and the external framing panel (34) is generally flat, thereby giving the final structure a rectangular configuration. Alternative structures comprising different angles of the external channels (19) and configuration of the external framing panels (34) will be readily apparent to persons skilled in the art based on the present disclosure.
An alternate embodiment of the present invention, can be prepared wherein the external framing panels (34) and external channels (19) are replaced with flexible support panel engaging surfaces (37) and flexible support panels (17). In such an embodiment, each locking beam (10a, 10b) would include, two, three or more flexible support panel engaging surfaces (37) to accommodate neighboring locking beam assemblies.
Furthermore, two, three, four or more parallel locking beam assemblies (100a, 100b, 100c, etc... ) can be joined into a final structure depending on the desired size of the final structure.
The external framing panels (34) can be any construction material commensurate with the desired construction project, such as wood, plastics, metal, sheet metal, fiberglass, composite materials, combinations thereof, or other compositions which will be readily apparent to the skilled artisan. The shape of the locking beams (10a, 10b), as well as the angle of the external channels (19), and shape of the external framing panels (34) can be chosen based on the desired final product. Alternate embodiments of the present invention can be seen in FIGs. 22a-f.
FIG. 22b depicts a linear locking beam assembly (100) of the present invention. FIG. 22a depicts an arched locking beam assembly (100) of the present invention, in accordance with the embodiment shown in FIGs. 20-21. Variations to the locking beam can be constructed which result in any desired size or shape, examples of which are depicted below.
FIG. 22c depicts an arched embodiment of two conjoined locking beam assemblies (100a, 100b) of the present invention. An embodiment of the present invention can be seen in FIG. 22c, wherein the locking beams (10a, 10b, etc..) have been prepared in an arched shape and multiple locking beams (10a, 10b) have been joined to create a hanger type construction. The locking beams (10a, 10b) are prefabricated to receive flexible support panels (17), which may run continuously or intermittently along the locking beam (10a, 10b). Where the flexible support panels (17) are located intermittently, along the locking beam (10a, 10b) the frame will have a cross-bar style of framing. This shape reduces the total weight and/or necessary materials for the overall frame construction. The crossbars style flexible support panels (17) can be prefabricated to lock into the flexible support panel engaging surface (37) of the locking beam (10a, 10b) in the same manner described previously, i.e., the ends of the crossbars style flexible support panels (17) can be prefabricated to match the channels (14a, 14b) and guide projection (13) of the locking beam (10a, 10b, etc.). Alternatively, the locking beams (10a, 10b, etc..) can be designed to receive the crossbars style exterior framing panels (34) in exterior channels (19) formed in the locking beams (10a, 10b) as shown in FIGs. 20-21. The locking beams (10a, 10b, etc..) employed in the arch construction shown in FIG. 22c employ the crossbars style external framing panels (34) running longitudinally along the length of the arch construction. Additionally, exterior framing panels (34) with correlating exterior channels (19) can complete the final structure. In an alternate construction style to prepare the hanger type construction depicted in FIG. 22c, locking beams (10a, 10b, etc ..) can be laid longitudinally along the ground and arched flexible support panels (17) can be employed to build the arch from the ground up. As shown in the FIG. 22c, the longitudinal lengths would be the locking beams (10a, 10b), and the arched vertical lengths correspond to the flexible support panels (17). In a further alternate embodiment shown in FIG. 22c, the locking beams (10a, 10b, etc ..) can be joined by intermittent or continuous external framing panels (34) at external grooves (19) located on the locking beams (10a, 10b, 10c, etc...). In the embodiment where the external framing panels (34) or flexible support panels (17) are placed intermittently along the locking beam (10a, 10b), the construction will have a cross-bar style of framing.
FIG. 22d depicts a wing type final product formed from a series of locking beams (10a, 10b, etc..) shaped to match the width of a wing. The locking beams can be joined in a series running the length of the wing, and covered with a solid exterior surface to complete the wing structure.
FIG. 22e depicts a dome type final product, and particularity an onion dome construction wherein the locking beams have been prefabricated to possess the external vertical shape of the onion dome.

Multiple locking beams (10a, 10b) can be employed along the longitudinal length of the bus frame based on its desired length. The locking beams (10a, 10b) can be joined as described above employing alternate configurations of the flexible support panel engaging surfaces (37), the flexible support panels (17), the external grooves (19), and external framing panels (34), to interconnect and strengthen the overall frame. Additional exterior framing panels (34) with correlating exterior channels (19) can complete the final exterior surface of the vehicular frame.
FIG. 23 depicts an embodiment of an extrusion line (500) that can be employed in the production of the locking beam (10) of the present invention.

The extrusion material can be any suitable material commonly used in the art, preferred embodiments of which are aluminum and plastics. Skilled artisans will readily be able to determine the necessary times and temperatures necessary for the breakdown of the extrusion material. Additional materials can be added to the extruder (50) to add desired qualities to the final locking beam (10), such as coloring agents, strengthening agents, plasticity agents, resilience agents, fireproofing agents, rust proofing agents, and combinations thereof. The use of additional materials necessary to complete the extrusion material will be readily apparent to the skilled artisan.
The extrudate then passes through a forming mold (51), which shapes the extruded material into the desired shape of the locking beam (10). As discussed previously, the locking beam will be prefabricated based on the desired needs of a particular construction project. The forming mold (51) will be prepared based on the desired construction project to have the opposite or negative shape of the desired locking beam (10). The shape can be imparted to the extrudate through the use of a prefabricated die or by an overall internal shape of the forming mold (51). Specifically, the shape of the flexible support panel engaging surface (37), retaining means (12), projection guide (13), load support surface (11), as well as other features discussed previously, can be applied to the extrudate during its passage through the forming mold (51).
During the passage of the extrudate through the forming mold (51), temperatures and time can be varied as is necessary based on the extrusion material employed.
In a preferred embodiment of the extrusion line (500), a tensioning device (52) is employed which feeds a tensioning element (21) into the forming mold (51). The tensioning element (21) can be a cable, metals or other flexible materials, a metal bar with threaded ends, fiberglass or a threaded bar. A preferred tensioning element (21) is rebar. Placing the tensioning element (21) inside the extrudate while it is inside the forming mold (51), allows for a one-step co-extrusion that forms a locking beam (10) with a tensioning element (21) embedded within the locking beam (10). The tensioning device (52) can be adjusted to impart the optimal tension to the tensioning means during the extrusion process. The skilled artisan will readily understand the required tensions based on the tensioning element (21), the extrudate and the desired qualities of the final locking beam (10).
The shaped extrudate then moves along the extrusion line (500) to a cooling table (53), where the shaped extrudate is allowed to cool and harden. The required cooling time and temperatures will be readily apparent to the skilled artisan, and can be varied based on the extrusion material employed. A pulling device (54) is located along the extrusion line (500) which pulls or advances the shaped extrudate along the extrusion line (500) from the direction of the extruder (50) and forming mold (51) towards a cutting device (55) and receiving table (56). The pulling device can optionally employ a conveyor belt type device to advance the shaped extrudate. Or pulling means will be readily apparent to the skilled artisan.
Next the shaped extrudate passes through a cutting device (55) which will cut the locking beam (10) into desired lengths based on either the specifications of the desired construction project or the optimal length for shipping, which can be followed by later cutting of the locking beam (10) to the desired length at the construction site.
Finally, the locking beam (10) is delivered to a receiving table (56) for storage of the locking beams or for additional processing steps that may be necessary based on the predetermined construction project. Additional steps can include, coloring, additional temperature treatments, application of fireproofmg or rust-proofing agents, and combinations thereof. Additional steps that may be employed will be readily apparent to the skilled artisan.
