The present disclosure relates generally to building surface baffles, for example, suitable for forming a room divider, a wall covering, an acoustical surface, or a ceiling surface. The present disclosure relates more particularly to asymmetrical baffles for forming a building surface.
The use of baffles for forming a building surface is a popular alternative to typical building surfaces that are solid and continuous. In contrast to a wall or ceiling formed by drywall or plaster, the baffles can allow air and light through while still defining a particular space, such as a room. For example, baffles can be used as a divider to separate two rooms while allowing light and air to pass through. Similarly, a ceiling surface that is formed using baffles can allow air in the room to access heating and ventilation equipment while being obscured behind the baffles. Likewise, lights that are installed above the baffles can be combined with, or used in place of, lights below the baffles to provide various different lighting effects.
Most baffles have a standard planar shape and appear as a series of parallel boards or panels. This configuration and the standard baffle shape is effective for forming a surface while also allowing air and light through the surface. However, this standard shape and configuration provides limited aesthetic options, and many building surfaces formed by baffles are visually similar.
Further, existing ceiling baffle systems are typically supported by a ceiling grid, that holds the baffles in a specific configuration. In some cases the ceiling grid is visible, and impacts the aesthetic of the surface. Moreover, the ceiling grid can dictate the position and spacing of the baffles, which limits the variability of the aesthetic of the surface.
The present inventors have recognized that a baffle construction for a building surface that provides an alternative baffle shape without visible supporting components would be attractive to architects and builders.
In one aspect, the present disclosure provides a baffle for a building surface, the baffle comprising:
In another aspect, the disclosure provides a building surface system comprising:
Additional aspects of the disclosure will be evident from the disclosure herein.
The accompanying drawings are included to provide a further understanding of the methods and devices of the disclosure, and are incorporated in and constitute a part of this specification. The drawings are not necessarily to scale, and sizes of various elements may be distorted for clarity. The drawings illustrate one or more embodiment(s) of the disclosure, and together with the description serve to explain the principles and operation of the disclosure.
As described above, the present inventors have noted that conventional baffles used for building surfaces provide limited options for the surface aesthetic. The present inventors have noted that a baffle construction for a building surface that provides an alternative baffle shape without visible supporting components would be attractive to architects and builders.
Accordingly, one aspect of the disclosure is a baffle for a building surface. The baffle includes an elongate body extending along an axis from a first end to a second end. The elongate body has a depth including a narrow portion that extends away from the axis along a first direction and a wide portion. The wide portion includes first and second projections that extend laterally outward from the first direction. The baffle also includes a first aperture extending into the first end of the elongate body along the axis and a second aperture extending into the second end of the elongate body along the axis.
Such a baffle is shown in
The configuration of baffle 110, where the narrow portion 140 extends in the first direction 114 from axis 112 and the wide portion 142 has projections 144, 146 that extend laterally outward from the first direction 114 allows the baffle to present a different appearance depending on which side the baffle is viewed from. For example, as shown and described further below, a row of baffles having the same construction as baffle 110 will present a surface when viewed from one side that appears significantly more closed than when viewed from the opposite side. In particular, when a viewer looks at a row of baffles 110, the overall size of the opening between the baffles 110 is fixed. However, if the viewer observes the row of baffles from the side that is closer to the narrow portions 140, the spacing between the baffles will appear larger and have a more open visual effect. On the other hand, if the viewer observes the row of baffles from the side that is closer to the wide portion 142, the spacing between the baffles will appear smaller and have a more enclosed and private visual effect. Of course, the baffles can also be arranged at angles to one another or in opposing directions to provide other interesting visual effects.
Baffle 110 also includes a first aperture 132 extending into first end 130 of elongate body 120 along axis 112. As shown in
In certain embodiments of the baffle as otherwise described herein, the first and second projections extend perpendicularly to the first direction. For example, in baffle 110, first projection 144 and second projection 146 both extend laterally outward, away from narrow portion 140, in a direction that is perpendicular to the first direction 114, i.e., the direction in which narrow portion 140 extends. Similarly, the first projection 244 and second projection 246 of baffle 210 shown in
In other embodiments, however, the first and second projections extend at an acute or obtuse angle to the first direction. For example, in some embodiments, the cross-section of the baffle has a configuration similar to the letter “Y” while in other embodiments, the cross-section of the baffle has a configuration similar an arrow. An embodiment of such a configuration is shown in
In certain embodiments of the baffle as otherwise described herein, the narrow portion of the elongate body is disposed on a first side of the axis and the wide portion is disposed on a second side of the axis that is opposite the first side. For example, as shown in
In certain embodiments of the baffle as otherwise described herein, the width of the baffle tapers between the wide portion and a distal end of the narrow portion. For example, the outer surface of elongate body 120 of baffle 110 tapers along a concave curved profile from the wide portion 142 to the narrow portion 140. The tapered shape of the elongate body forms a smooth transition between the projections 144, 146 of wide portion 142 to the long extension of narrow portion 140. Similarly, the outer surface of elongate body 220 of baffle 210 also tapers between the wide portion 242 and narrow portion 240. Unlike that of baffle 110, however, the surface of baffle 210 tapers toward narrow portion 240 at a straight angle rather than a curved profile. Still, in other embodiments, the first and second projections extend sharply outward from the narrow portion with an abrupt rather than gradual change in the width of the elongate body.
In certain embodiments of the baffle as otherwise described herein, the first and second apertures are formed by a through hole that extends along the axis. For example, as shown in
In certain embodiments of the baffle as otherwise described herein, the axis is at the center of the through hole. For example, elongate body 120 of baffle 110, through hole 138 is circular, and axis 112 is at the center of through hole 138. In other embodiments, the through hole may have a different shape and the axis may be positioned at another location that is off-center with respect to the through hole or is outside the through hole entirely.
In certain embodiments of the baffle as otherwise described herein, the elongate body includes a hollow cylindrical core surrounding the axis. For example, baffle 110 has such a configuration. Specifically, elongate body 120 includes a cylindrical core 150 that forms an annular wall surrounding axis 112. The cylindrical core 150 has a similar configuration to a pipe and the open interior forms the through hole 138 and apertures 132, 136 at the respective ends 130, 134 of elongate body 120. The wall of the cylindrical core 150 forms a solid structure for supporting the baffle when a rod or pins are placed in the apertures 132, 136. Moreover, the cylindrical core can also support the outer features of baffle. For example, each of the narrow portion 140, first projection 144, and second projection 146 extends outward from cylindrical core 150 which holds and supports these extended features.
In some embodiments, each end of the elongate body includes a single location configured to receive a corresponding pin segment. For example, baffle 110 is configured to receive a pin segment at each end 130, 134 within the cylindrical core 150. In other embodiments, the baffle includes a plurality of locations configured to receive pin segments. For example, in some embodiments, the baffle includes several openings configured to receive respective pin segments in the form of mechanical fasteners, such as screws. An embodiment of such a configuration is shown in
In some embodiments, the body of the baffle is configured to directly engage and secure the pin segments. For example, the cylindrical core 150 of baffle 110 is configured to receive a pin segment so as to directly secure the pin segment to the elongate body 120 of the baffle. In other embodiments, the baffle may include end caps that are attached to the elongate body and secure a pin segment at the respective end of the baffle. For example,
The pin segment 470 may be used to secure baffle 410 in a support structure, as described in further detail below. A collar 475 is secured to pin segment 470 and may be used to secure the pin segment 470 in place in the support structure.
Further, while some embodiments include openings specifically shaped to receive a pin segment, such as the hollow core 150 of baffle 110 and the openings 450 of baffle 410, in other embodiments, the aperture does not include an opening specifically shaped to receive a pin segment. Instead, in some embodiments, the interior of the baffle includes an irregular hollow cross section, for example based on the exterior shape of the baffle or other design considerations. An embodiment of such a configuration is shown in
In certain embodiments of the baffle as otherwise described herein, the first and second projections include a hollow interior. Likewise, in certain embodiments of the baffle as otherwise described herein, the narrow portion includes a hollow interior. For example, the outside of elongate body 120 of baffle 110 is formed by an exterior wall 148 that provides the outside surface of each of the narrow portion 140 and projections 144, 146. The exterior wall 148 is coupled to the cylindrical core 150 at various locations around the perimeter of cylindrical core 150. Inside exterior wall 148, each of the narrow portion 140 and projections 144, 146 has a respective hollow interior 158, 154, 156. For example, first projection 144 has a hollow interior 154 between cylindrical core 150 and exterior wall 148 and second projection 146 also has a hollow interior 156 on the opposite side of cylindrical core 150 between cylindrical core 150 and exterior wall 148. Likewise, narrow portion 140 includes a hollow interior between opposing sides of the exterior wall 148 along the first direction 114.
In certain embodiments of the baffle as otherwise described herein, the elongate body is formed as a single integral piece. For example, in some embodiments, the elongate body is formed by a single material that extends throughout the elongate body without mechanical or adhesive connections holding separate parts together. On the other hand, in other embodiments, the elongate body is formed by two or more pieces that are attached to one another with mechanical fasteners, such as screws. Likewise, in other embodiments the elongate body is formed by two or more pieces that are bonded to one another. Further still, in some embodiments, the elongate body includes pieces that are both mechanically fastened and bonded to one another.
In certain embodiments of the baffle as otherwise described herein, the elongate body is an extruded member. For example, in some embodiments the elongate body of the baffle is formed by an extruder that extrudes the elongate body along its length. Accordingly, in some embodiments, the elongate body has a uniform cross-sectional shape along its length. For example, in some embodiments, the elongate body is an extruded metal component. In other embodiments, the elongate body is an extruded plastic component. In other embodiments, the elongate body is cast or molded. In other embodiments, the elongate body is machined or welded from several pieces. Further, in some embodiments, the elongate body is made by an additive manufacturing process, such as 3D printing.
In some embodiments, the elongate body is formed of a metal. For example, in some embodiments the elongate body is formed of aluminum, steel or another metal. Alternatively, in some embodiments the elongate body is formed of plastic. For example, in some embodiments the elongate body is formed of one or more of polypropylene, polyethylene, polyvinyl chloride (PVC), acrylonitrile styrene acrylate (ASA), acrylonitrile ethylene styrene (AES), polyurethane, or acrylonitrile butadiene styrene (ABS). Further still, in some embodiments, the elongate body is formed of a fiberglass material or reinforced material. Likewise, in some embodiments, the elongate body is formed of a natural material, such as wood, bamboo or a fibrous material. In other embodiments, the elongate body is formed of some combination of metal, plastic, fiberglass, and a natural material.
In certain embodiments of the baffle as otherwise described herein, the elongate body includes an internal frame formed of a first material and a covering formed of a second material. Such an embodiment is shown in
In some embodiments, the covering fully surrounds the internal frame such that the internal frame is not visible. For example, covering 662 of elongate body 620 fully surrounds internal frame 660 along the length of baffle 610. In other embodiments, portions of the internal frame are concealed by the covering while other portions are left exposed. In some embodiments, the exposed and concealed areas of the internal frame vary around the perimeter of the elongate body. In other embodiments, the exposed and concealed areas vary along the length of the elongate body.
In certain embodiments of the baffle as otherwise described herein, the second material comprises felt. For example, in some embodiments, the elongate body includes a felt covering over a metal internal frame. The use of felt can help provide acoustic characteristics to the baffles to help attenuate sounds. In other embodiments, the elongate body includes a felt covering over a plastic internal frame. Still, in other the elongate body includes a plastic covering over a metal internal frame.
In certain embodiments of the baffle as otherwise described herein, the elongate body is covered with a coating. In some embodiments, the coating is decorative and imparts a particular visual aspect to the baffle. For example, in some embodiments the coating is opaque and has a particular color. In other embodiments, the coating is transparent. In some embodiments, the coating is variegated, such that different portions of the elongate body have different colors. For example, in some embodiments, the coating is partially transparent such that sections of the underlying material of the elongate body show through the coating while other sections are overlaid with an opaque covering. In some embodiments the coating includes an image of a natural product, such as wood.
In some embodiments, the coating is provided as a liquid that is sprayed or otherwise applied onto the elongate body. In other embodiments the coating is a film or laminate that is stretched over or otherwise applied to the elongate body. Still, in other embodiments the coating is a coextruded layer formed with the elongate body during an extrusion or molding process.
In certain embodiments of the baffle as otherwise described herein, the elongate body includes a light source. Such an embodiment is shown in
In some embodiments the light source includes a plurality of LEDs. For example, light source 764 in elongate body 720 of baffle 710 includes a plurality of LEDs 766 arranged in a line along the length of elongate body 720. The term LED as used herein includes conventional LEDs, organic light emitting diodes (OLEDs) and quantum dot LEDs. In other embodiments, the light source may be in the form of a lamp, such as an incandescent, fluorescent, or halogen bulb. Still, in other embodiments, the light source may be in the form of another lighting element, such as a laser or an optical fiber.
In some embodiments, the light source includes a lens. For example, light source 764 of baffle 710 includes a lens 768 disposed over LEDs 766. Lens 768 forms a portion of the outer surface of elongate body 720, thereby providing a cohesive appearance.
In certain embodiments of the baffle as otherwise described herein, a length of the baffle from the first end to the second end is at least 3 feet in length, e.g., at least 4 feet, e.g., at least 6 feet, e.g., at least 8 feet. Further, in certain embodiments of the baffle as otherwise described herein, a length of the baffle from the first end to the second end is no more than 40 feet in length, e.g., no more than 30 feet, e.g., no more than 25 feet, e.g., no more than 20 feet. For example, in some embodiments, the baffle has a length in a range from 3 feet to 40 feet, e.g., 4 feet to 30 feet, e.g., from 6 feet to 25 feet, e.g., from 8 feet to 20 feet.
In certain embodiments of the baffle as otherwise described herein the depth of the baffle is at least 3 inches, e.g., at least 4 inches, e.g., at least 6 inches. Further, in certain embodiments of the baffle as otherwise described herein, the depth of the baffle is no more than 4 feet, e.g., no more than 3 feet, e.g., no more than 2 feet.

For example, in some embodiments, the baffle has a width in a range from 1 inch to 12 inches, e.g., from 2 inch to 8 inches, e.g. from 2 inches to 6 inches.
In another aspect, the disclosure provides a building surface system that includes a first support structure, a second support structure, and a plurality of baffles according to the disclosure extending from the first support structure to the second support structure. Each baffle of the system is supported at its first end by a respective first pin segment that is inserted into the first aperture and is supported at its second end by a respective second pin segment that is inserted into the second aperture.
Such a building surface system is shown in
The baffles 810 may be coupled to the respective support structures 802, 804 by inserting the ends of the pin segments 872, 874 into openings in the respective support structures 802, 804 and then securing the pin segments 872, 874 in place. For example, first pin segment 872 may initially be inserted into the opening in first support structure 802 so that first pin segment 872 reaches the upper end of first support structure 802. Second pin segment 874 may then be aligned with the opening in second support structure 804. The baffle 810 may then be lowered so that second pin segment 874 is inserted into second support structure 804. The baffle 810 and pin segments 872, 874 can then be secured in place using a collar 875 that surrounds first pin segment 872 and hinders upward movement of the baffle 810.
In certain embodiments of the building surface system as otherwise described herein, each pair of first and second pin segments is formed by a rod that extends through the entire elongate body. For example, in some embodiments a rod is coupled to each baffle and extends through the baffle from the first aperture at the first end to the second aperture at the second end. Moreover, the rod extends beyond the two ends of the baffle to be secured within the first and second support structures. Accordingly, the rod that corresponds to each baffle forms both the first pin segment and the second pin segment associated with that baffle. In other embodiments, the first and second pin segments are discrete components. For example, in building surface system 800, the first pin segment 872 and second pin segment 874 are separate and respectively positioned at opposing ends of the baffle 810.
In certain embodiments of the building surface system as otherwise described herein, each of the baffles is rotatable about a respective axis. For example,
In certain embodiments of the building surface system as otherwise described herein, the first support structure is a first rail that holds the respective first ends of the baffles at respective positions spaced along the length of the first rail. For example, the first support structure of building surface system 800 is configured as a first rail 802 that supports the respective first pin segments 870 at regular intervals along the length of the first rail 802. Accordingly, the baffles 810 are similarly held at regular intervals based on the spacing of the first pin segments 872 along the first rail 802. Similarly, the second support structure of building surface system 800 is also configured as a second rail 804 that supports the respective second pin segments 874 along regular intervals. Similarly, the first support structure of building surface system 100, as shown in
In some embodiments, the rails are secured over the surface of a building structure, such as a floor, enclosed ceiling, or a wall. In other embodiments, the rails are embedded in such a building structure. Still, in other embodiments the rails are suspended from a building structure and not immediately adjacent to any other structures.
In some embodiments, either or both of the support structures are not rails and have another configuration. For example, in some embodiments, the first support structure is formed by a ceiling, a floor, or a wall that includes receptacles for the pin segments.
In some embodiments, the rails that support the baffles are linear. For example, the first rail 802 and the second rail 804 in building surface system 800, as shown in
In some embodiments, the length of the first rail is at least 3 feet, e.g., at least 6 feet, e.g., at least 8 feet. The length of the first rail can vary depending the size of the building surface that is being installed and the number of baffles that are being used. In some embodiments, the length of the first rail is limited by manufacturing and transportation limitations. For example, in some embodiments, the first rail is no more than 50 feet, e.g., no more than 25 feet. In other embodiments, the first rail is longer.
In certain embodiments of the building surface system as otherwise described herein, the first pin segments are held in the first rail. For example, as shown in the cross-sectional view of
In certain embodiments of the building surface system as otherwise described herein, the first rail includes an insert that has a plurality of sockets configured to receive the first pin segments. For example, as shown in
In certain embodiments of the building surface system as otherwise described herein, each of the first pin segments is attached to a respective fastener that is secured to the first rail. Such an embodiment is shown in
In certain embodiments of the building surface system as otherwise described herein, at least one of the first rail and second rail includes a conductor for providing power to the baffles. For example, second rail 1204 of building surface system 1200 includes a series of electrical conductors 1290 configured to provide power to baffle 1210. For example, as explained above, in some embodiments the baffle includes a light source, and the electrical conductor may provide electrical power for illuminating the light source. In other embodiments, the rail includes conductors for providing power to other components. For example, in some embodiments, the conductor provides power to actuators configured to rotate the baffles, as described above. The rail may also include conductors for carrying signals to operate components, such as the light source or an actuator.
In certain embodiments of the building surface system as otherwise described herein, the axes associated with each of the plurality of baffles lie in a common plane. For example, the axes of baffles 810 of building surface system 800 are disposed in a common plane, as shown in
In certain embodiments of the building surface system as otherwise described herein, the baffles extend vertically forming a room divider. For example, building surface system 800, shown in
In other embodiments, the building surface system connects directly to a wall or ceiling surface, or is attached in a manner to be offset from such surfaces by a minimum distance to allow for rotation of the baffles along their axes. In such cases, the baffles and building surface system may be providing an illumination source, a shading function, or acoustical control or acoustical dampening to the building space.
In other embodiments, the baffles extend horizontally forming a ceiling surface. For example, in some embodiments, the baffles of the building surface system are ceiling baffles and define a ceiling surface that separates a lower occupied space from a plenum above the ceiling surface.
It will be apparent to those skilled in the art that various modifications and variations can be made to the processes and devices described here without departing from the scope of the disclosure. Thus, it is intended that the present disclosure cover such modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
