The present invention relates generally to a bridging lintel with support hangers for an insert and block system for an outdoor structure constructed with structural blocks. The bridging lintel with support hangers forms a portion of the insert and positions, retains and secures the insert within courses of the structural blocks used in the construction of the outdoor structure.
Outdoor fireplaces, outdoor kitchens and other outdoor living structures have become increasingly popular, either as a landscape feature or to provide a functional outdoor gathering and/or relaxing space. However, construction of such outdoor structures can be labor intensive, labor specialized and consequently expensive. Typical outdoor fireplaces and other similar outdoor structures can be constructed from brick, block or stone components that may have to be custom built, and in some cases custom produced, for each installation. Additionally, the bricks, blocks or stone components used in the construction of these outdoor structures usually requires joint width or spacing and mortar between courses to position or hide lintels used to span desired gaps or openings in the outdoor structure, thereby increasing the need for specialized labor and increasing the difficulty and cost of constructing the outdoor structure. Further, some bricks, blocks or stone components require on site field cutting to properly position and place lintels within the structure, further increasing the difficulty and cost of construction.
It would be desirable to provide a system of blocks for constructing an outdoor fireplace, outdoor grill station, outdoor kitchen or other outdoor structure that combines the ease of installation of modern segmental block units with the attractive appearance of a random or irregularly patterned visually exposed surface. The block system should be efficient, easy to use and allow the construction of structures with 90 degree corners and the construction of freestanding structures. It would further be desirable to provide a lintel with support hangers that forms a portion of an insert for the outdoor structure and that positions, retains and secures the insert within the structural blocks used in the construction of the outdoor structure without the use of mortar, joint spacing, block field cutting or other specialized labor.

In this application, “upper” and “lower” refer to the placement of the structural block in a structure. The lower, or bottom, surface of the block may be placed such that it faces the ground, the lower surface may be the bottom surface of the block as manufactured in a mold cavity or may be the top surface of the block as manufactured in a mold cavity (the upper surface may be the top surface of the block as manufactured in a mold cavity or the bottom surface of the block as manufactured in a mold cavity), as such, the block may or may not be oriented in the wall in a flipped position relative to its manufacture in the mold cavity. During construction of a structure, one row of blocks is laid down, forming a course. An upper course may be formed on top of this lower course by positioning the lower surface of one block on the upper surface of another block. It should be understood that the placement of a block in each course of a wall is not limiting and any of the front, rear or orthogonal side face of any block may be used to form the front (or visually exposed) surface of the structure. The front and rear faces (and side surfaces) of one block may also have different surface areas and may have any texture or pattern as desired. These features contribute to the random appearance and the irregularity of the pattern of the visually exposed surfaces of the structure. Additionally, the blocks can be positioned with the top surface (and bottom surface) facing upward or downward.
Referring to
Multiple pin receiving apertures or pin holes may be provided in each of blocks 100 (a/b/c), and these preferably extend through the thickness of the block. The apertures are in a direction perpendicular to the upper and lower surfaces. For example, pin holes extend through the block and open into channels 122 (not shown in
Generally, when constructing an outdoor structure of the present invention, a trench may be excavated to a pre-selected depth and partially filled with a level base of granular material such as crushed stone or sand. A base layer or lowermost course of blocks 100a/b/c is then placed with the bottom surfaces facing downward and is leveled onto the crushed stone or sand. The blocks of the course are placed side to side to create the specific shape and size of the outdoor structure. Upper courses of blocks 100a/b/c are stacked on lower courses of blocks. In some courses of blocks, specifically dimensioned gaps or voids (sometimes multiple gaps and voids) are left to allow/accommodate the placement and positioning of an insert within the structure. The gaps or cavities may extend the height of several courses of blocks to accommodate the height of the insert. When a specific course of blocks has been assembled having the properly dimensioned gap or void necessary to accommodate the dimension of the insert, the outward extending portions of the structural hangers of the bridging lintel of the insert are positioned on the top surfaces of the blocks directly adjacent to the gap or void in the specific course of blocks of the structure. The structural hangers allow the bridging lintel to span or bridge the uppermost length of the gap or void. The structural hangers allow the bridging lintel to be substantially or mostly flush or level and mostly in the same horizontal plane with the top surfaces of the structural blocks 100a/b/c of this course of blocks. Any remaining upper course of blocks are then stacked as necessary to complete the outdoor structure. The bridging lintel also supports the upper courses of blocks positioned directly above the bridging lintel and allows the upper courses of blocks supported by the lintel to be level with and/or substantially flush with the other blocks of the same courses without any manipulation of the blocks at the construction site.
It should be understood that blocks 100a/b/c may be positioned in courses with the receiving channels facing upward. In these applications, a reconfiguration of the bridging lintel of the present invention would allow for this reversed block placement orientation.
The grills in
It should be understood that any or all of the structures shown herewith could be constructed with the bottom surface of the blocks facing upward such that the receiving channel is on the top surface and such that the support hangers are positioned on the bridging lintel of the insert such that the outward extending segments are configured to be accepted and retained within the receiving channel of the top surface of blocks in a course that is level and in the same horizontal plane as the uppermost surface of the bridging lintel.
It should also be understood that the bridging lintel and support hanger system could be used in any desired structure, such as walls, fences, etc., and could be made from any desired material. Additionally, the bridging lintel and support hanger system could be used to position, retain and secure any desired insert within a structure. These inserts could, for example, be doors, gates, drains, vents, refrigerators, ovens, warming drawers, grills, etc.
It should also be understood that the bridging lintel and support hanger system could form the bottom portion of an insert in addition to or alternative to forming the top portion of an insert.
Although particular embodiments have been disclosed herein in detail, this has been done for purposes of illustration only, and is not intended to be limiting with respect to the scope of the invention. In particular, it is contemplated by the inventor that various substitutions, alterations, and modifications may be made to the invention without departing from the spirit and scope of the invention. For instance, the choice of materials or variations in the shape or angles at which some of the surfaces intersect are believed to be a matter of routine for a person of ordinary skill in the art with knowledge of the embodiments disclosed herein.
