    Abstract: Non-masonry building block components, including a standard hollow-bodied block component with horizontal and vertical locking capabilities which removes the need for bonding material such as glue, mortar or other adhesives. Modified dovetails on the upper and lower surface of the building components prevent vertical movement while resistance locks on each end of the block prevent horizontal movement. Typically, use of the non-masonry building components would allow for constructing permanent or temporary structures having vertical and horizontal channels in which to allow plumbing or electrical conduit. The incorporation of materials, such as sand or similar substance, would form a bullet-resistant barrier for use in military operations. Additionally, structures formed from the block components could easily be assembled or disassembled on site without the need for skilled labor, specialized tools, demolition and clean up.

  • Patent number: 8069630
    Abstract: A system and method for forming a filter media support system with multiple locking mechanisms. The support system comprises two or more interlocking rows of support blocks. One or more slides and one or more guides protrude from the side walls of the blocks. Each guide is conformed to receive one slide from a neighboring block, forming a first locking joint. The side walls also comprise one or more nubs and one or more recesses. Each nub is conformed to fit within one recess of a neighboring block, forming a second locking joint. In one embodiment, the method for assembling the support system comprises aligning a slide of a first support block with a guide of a second support block. The slide of the first support block is vertically moved into the guide of the second support block. Force is applied so that the nubs are flexed within the recesses.

  • Patent number: 8037656
    Abstract: A hardwood floor system with press down locking mechanism. Each floor board is equipped with both male and female locking mechanisms. The male locking mechanism of a floor board can be locked into the female locking mechanism of an adjacent floor board by simply exerting downward force on the floor board. The female locking mechanism is equipped with a spring slot that enables easy engagement of male and female locking mechanisms. The invention may be applied not only floor boards, but also to wall tiles and roof tiles.

  • Patent number: 7997041
    Abstract: A system and method for forming a filter media support system with dual locking mechanisms. The support system comprises two or more interlocking rows of support blocks. One or more slides and one or more guides protrude from the side walls of the blocks. Each guide is conformed to receive one slide from a neighboring block, forming a first locking joint. The side walls also comprise one or more posts and one or more sockets. Each post is conformed to fit within one socket of a neighboring block, forming a second locking joint. In one embodiment, the method for assembling the support system comprises aligning a slide of a first support block with a guide of a second support block. The slide of the first support block is vertically moved into the guide of the second support block. Force is applied so that the posts snap-lock into the sockets.

  • Patent number: 7963038
    Abstract: To fabricate a joint in a panel, a groove is generated and the panel is bent along the groove. The panel includes a first skin, second skin, and core. The core is sandwiched between the first skin and the second skin. The groove passes through the first skin and at least a portion of the core. The groove includes a set of tabs and a corresponding set of slots. The set of tabs intermesh with the set of slots in response to bending the panel along the groove.

  • Patent number: 7954295
    Abstract: A locking system for mechanical joining of floorboards. For horizontal mechanical joining there is a projecting portion with a locking element which cooperates with a locking groove in an adjacent board. A tongue-and-groove joint for vertical mechanical joining has cooperating upper abutment surfaces and cooperating lower abutment surfaces which are essentially parallel with the principal plane of the floorboards and of which the lower abutment surfaces are positioned essentially outside the outer vertical plane, i.e. displaced relative to the upper abutment surfaces. The tongue is movable at an angle into the groove and the locking element is insertable into the locking groove by mutual angular movement of the boards about the joint edges.

  • Patent number: 7856773
    Abstract: The invention relates to a modular construction system for full size or toy/model size buildings. The basic structure is made of interconnectable panels, which are grouped into four main types: base panels, wall panels, ceiling panels, and roof panels. Each panel has a plurality of service conduits extending therethrough for passing all of the service requirements for the building, e.g. electrical, plumbing, air conditioning, vacuum etc, without having to cut or drill through the existing structure. Each vertical wall panel has upper and lower connector blocks for mating with the horizontal ceiling and base panels, respectively. The connector blocks also align the service conduits of the wall panel with the service conduits of the ceiling and base panels.
