COLLAPSIBLE STRUCTURAL FRAME SYSTEM FOR A SHEET-LIKE BUILDING

MATERIAL

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is a PCT International Application of U.S. Provisional Patent Application No. 62/725,611 filed on August 31, 2018. The disclosure of the above application is incorporated herein by reference.

FIELD

[0001] The present invention relates to building systems. Particular embodiments of the invention relate to collapsible systems for forming the structure of a soffit or similar framework. Particular embodiments provide the structure for holding drywall or other sheet-like finish material.

BACKGROUND

[0002] Many office buildings and other buildings have interior designs that include areas of flat ceilings and walls. Some of these buildings also include soffits or other features that include multiple angles between relatively small flat areas. For example, an upper area of an occupiable building space at the junction between a wall and the ceiling can include a rectangular (or other shape) boxed out area having a vertical surface sometimes referred to as a facia and a horizontal surface that is known as a soffit. A structure is traditionally built and then drywall or some other building material (often a sheet material) is fastened to the structure.

[0003] A problem exists in that traditionally the structure of the soffit and facia is stick-built by a worker in the field from wood or metal studs or other stock pieces that need to be custom cut and fitted. This procedure is time consuming and requires significant care to ensure that all the appropriate angles and lengths are identical so that a uniform structure results.

[0004] Accordingly, embodiments of the invention provide a system for quickly and easily constructing a dimensionally uniform structural framework for a flat area, soffit, fascia, or other building area. SUMMARY

[0005] Embodiments of the invention provide a solution to the above problem by allowing more flexibility in grid design and more flexibility in ceiling tile construction and arrangement.

[0006] In one aspect, a collapsible structural frame is provided that is configured to provide a structure to which building material sheets are attached to form a surface. The frame includes a first frame portion that corresponds to a first portion of the surface and is configured to receive a first sheet of the building material; a second frame portion that corresponds to a second portion of the surface and is configured to receive a second sheet of the building material; a pivoting mechanism that attaches the second frame portion to the first frame portion and has a pivoting axis, the pivoting mechanism permitting the second frame portion to rotate about the pivoting axis relative to the first frame portion, and the pivoting mechanism permitting the second frame portion to rotate about the pivoting axis from an undeployed state to a deployed state; and a locking mechanism that fixes a relative position of the first frame portion and the second frame portion in the deployed state. The undeployed state is a folded state compared to the deployed state.

[0007] Other embodiments of the present invention include a building system comprising the previously discussed collapsible structure frame in the deployed state.

[0008] In another aspect, a collapsible structural frame is provided that is configured to provide a soffit structure to which building material sheets are attached to form a first soffit surface and a second soffit surface. The frame includes a first frame portion that corresponds to the first soffit surface and is configured to receive a first sheet of the building material; a second frame portion that corresponds to the second soffit surface and is configured to receive a second sheet of the building material; a pivoting mechanism that attaches the second frame portion to the first frame portion and has a pivoting axis, the pivoting mechanism permitting the second frame portion to rotate about the pivoting axis relative to the first frame portion, and the pivoting mechanism permitting the second frame portion to rotate about the pivoting axis from an undeployed state to a deployed state; and a locking mechanism that fixes a relative position of the first frame portion and the second frame portion in the deployed state at a deployed angle. The undeployed state is a folded state compared to the deployed state, and the deployed angle is more than 0 degrees and less than 180 degrees.

[0009] In another aspect, a collapsible structural soffit frame is provided to which a building material sheet is attached to form a soffit surface. The frame includes a first rigid member; a second rigid member; a first collapsible member that connects the first rigid member to the second rigid member, the first collapsible member having a collapsed position and a deployed position; and a second collapsible member that connects the first rigid member to the second rigid member, the second collapsible member having a collapsed position and a deployed position. In the deployed position of both the first and second collapsible members the first and second collapsible members are structural members configured to support the building material sheet.

[0010] Other embodiments of the present invention include a building system comprising the previously discussed collapsible structure soffit frame in the deployed state.

[0011] Other embodiments of the present invention include a method of installing a soffit comprising: a) providing a collapsible structural frame in a folded state, the collapsible structural frame configured to provide a structure to which building material sheets are attached to form a surface; b) converting the collapsible structural frame from the folded state to a deployed state and fastening the collapsible structural frame to a preexisting support; and c) fastening at least a sheet of building material to the surface of the collapsible structural frame.

[0032] Figure 1 shows an example of a traditional building structure for supporting drywall panels to form a soffit and facia. The thickness of some members in the figures is not to scale and are made thicker in proportion to other members for clarity. Actual members may be relatively thin sheet metal or other material such as wood, plastic, composite or other material.

[0033] In Figure 1, a structural frame 10 includes an upper horizontal section formed by members 50, a vertical section formed by members 60 and a lower horizontal section formed by members 70. In this example, the upper horizontal section and the vertical section intersect at a right angle, and the vertical section and the lower horizontal section intersect at a right angle. In other examples, different angles exist between the particular sections and the sections have different relative lengths. Members 50, 60, 70 are, in this example, longitudinal members having a“T” shaped cross section. Angles 20, 30, 40 are, in this example, longitudinal members having an“L” shaped cross section. Although Figures 1-3 show surfaces 54, 64, 74 being offset from surfaces 21, 22, 31, 32, 41, 42 by the thickness of angles 20, 30, 40, other examples are fabricated so that surfaces 54, 64, 74 are flush with surfaces 21, 22, 31, 32, 41, 42. In this example, member 50 is fixed to member 60 by two screws 80, and member 60 is fixed to member 70 by two screws 85.

[0034] The structural frame 10 may comprise a first frame portion that may form a first portion of the surface and is configured to receive a first sheet of the building material. The first frame portion may comprise a first longitudinal member 50 and a second longitudinal member 40, the first longitudinal member 50 arranged orthogonal to the second longitudinal member 40.

[0035] The structural frame 10 may further comprise a first pivoting mechanism 80 that attaches the second frame portion to the first frame portion and has a first pivoting axis. The first pivoting mechanism 80 may permit the second frame portion to rotate about the first pivoting axis relative to the first frame portion, and the first pivoting mechanism 80 permitting the second frame portion to rotate about the first pivoting axis from an undeployed state to a deployed state. The undeployed state may be a folded state compared to the deployed state. [0036] The structural frame 10 may further comprise a first locking mechanism that fixes a relative position of the first frame portion and the second frame portion in the deployed state.

[0037] The first longitudinal member 50 may have a T-shaped cross-section. The T-shaped cross- section of the first longitudinal member 50 may comprise a bottom flange 54 that forms part of the first portion of the surface.

[0038] The second longitudinal member 40 may have an L-shaped cross-section. The L-shaped cross-section of the second longitudinal member 40 may comprise a bottom flange 64 that forms part of the first portion of the surface.

[0039] The second longitudinal member 40 of the first frame portion may extends along a direction that is substantially parallel to the first pivoting axis.

[0040] The structural frame 10 may comprise a second frame portion may form a second portion of the surface and is configured to receive a second sheet of the building material. The second frame portion may comprise a third longitudinal member 60 and a fourth longitudinal member 20, the third longitudinal member 60 arranged orthogonal to the fourth longitudinal member 20.

[0041] The third longitudinal member 60 may have a T-shaped cross-section. The T-shaped cross- section of the third longitudinal member 60 may comprise a bottom flange 64 that forms part of the first portion of the surface.

[0042] The fourth longitudinal member 20 may have an L-shaped cross-section. The L-shaped cross-section of the fourth longitudinal member 20 may comprise a bottom flange 22 that forms part of the first portion of the surface.

[0043] The fourth longitudinal member 20 of the second frame portion may extends along a direction that is substantially parallel to the first pivoting axis.

[0044] The structural frame 10 may comprise a third frame portion that corresponds to a third portion of the surface and is configured to receive a third sheet of the building material. The third frame portion may comprise a fifth longitudinal member 70. The fifth longitudinal member 70 may be arranged orthogonal to the fourth longitudinal member 20.

[0045] The structural frame 10 may further comprise a second pivoting mechanism 85 that attaches the third frame portion to the second frame portion and has a second pivoting axis. The second pivoting mechanism 85 may permit the second frame portion to rotate about the second pivoting axis relative to the third frame portion, and the second pivoting mechanism 85 may permitting the second frame portion to rotate about the second pivoting axis from an undeployed state to a deployed state.

[0046] The structural frame 10 may further comprise a second locking mechanism that fixes a relative position of the second frame portion and the third frame portion in the deployed state.

[0047] The fifth longitudinal member 70 may comprise a T-shaped cross-section. The T-shaped cross-section of the fifth longitudinal member 70 may comprises a bottom flange 74 that forms part of the third portion of the surface.

[0048] The fifth longitudinal member 70 of the third frame portion may extends along a direction that is substantially orthogonal to the second pivoting axis.

[0049] Figure 2 is a perspective view of frame 10 and Figure 3 is a top view of frame 10. These figures help illustrate the stick-built nature of this example of a traditional building structure for supporting drywall panels.

[0050] Figures 4 and 5 show an example of an embodiment of the invention that simplifies the work needed in the field to create a frame for supporting drywall or other sheet-like material. In this example, framework 100 has two panels 200, 300 that are hinged at a folding line 150 such that panels 200, 300 can be folded into a condition in which panel 200 is positioned on top of panel 300, as shown in Figure 5. This example provides a frame that can be constructed off-site and then quickly and easily unfolded on-site to provide a dimensionally correct framework.

[0051] The sheet-like material may be formed from a first sheet of the building material and a second sheet of the building material. The first sheet and the second sheet may be two completely separate sheets of material. In another embodiment, the first and second sheets may be formed from a single panel of building material, whereby the single panel has a V-shaped cut formed into one of the major surfaces, thereby allowing the single panel to be folded to a shape conforming to a first frame portion and a second frame portion of the frame, whereby the singe panel extends continuously from the first frame portion to the second frame portion. The V-shaped cut may be formed such that a 90 degree fold is formed on the single panel. Other fold angles may range from 30 to 170 degrees - including all angles and subranges there-between.

[0052] Panel 200 has a longitudinal member 210 and a parallel longitudinal member 215 that establish the length of panel 200. Two end transverse members 220 bridge between longitudinal members 210, 215. In this example, two interior transverse members 230 are parallel to end transverse members 220 and bridge between longitudinal members 310, 315. Similarly to panel 200, panel 300 has a longitudinal member 310 and a parallel longitudinal member 315 that establish the length of framework panel 300. Two end transverse members 320 bridge between longitudinal members 310, 315. In this example, two interior transverse members 330 are parallel to end transverse members 320 and bridge between longitudinal members 310, 315.

[0053] Figure 5 shows framework 100 in a folded state where panel 200 is rotated relative to panel 300 about folding line 150 such that panel 200 is positioned on top of panel 300. The movement of panel 200 relative to panel 300 can be controlled by one or move hinging mechanisms. The hinging mechanism can be located at folding line 150 and be a simple hinge, or they can be located remotely from folding line 150 and/or be some other type of mechanism that permits the desired relative movement of panels 200, 300. The hinging mechanism can be configured to allow relative rotation of the panels 200, 300 through any angle of rotation. For example, as shown in Figure 4, panels 200, 300 can rotate to a position at which they are 180 degrees from each other. In other examples, panels 200, 300 can rotate to a position in which they are more or less than 180 degrees from each other. For example, in the case of a common soffit in a building space (or other application), panels 200, 300 can be moved to a position in which they are 90 degrees from one another.

[0054] One or more locking mechanisms can be provided to lock panels 200, 300 in a desired position relative to one another. Such locking mechanisms can be of any configuration that securely holds the panels in the desired position sufficiently to allow the attachment of the drywall, or other, building panels. Figures 6-11 show an example of locking mechanisms in accordance with the invention.

[0055] Figure 6 shows an example of a framework 600 in accordance with embodiments of the invention. Framework 600 has an upper member 700 that is T-shaped in cross-section. The T- shaped cross-section is formed by a rib portion 710 and a flange portion 720 that extends laterally away from rib portion 710 on both sides of rib portion 710. While upper member 700 is shown as a T-shaped member in this example, in other examples upper member 700 has an L-shaped cross- section, a box-shaped cross-section, or another shaped cross-section. Any appropriately shaped cross-section can be used as long as it is sufficiently strong to support the drywall or other building sheet that is to be attached to framework 600. [0056] Framework 600 has a middle member 800 that is attached to upper member 700 by a swiveling joint 805 that can be, for example, a bolt, pin, rivet, or other swiveling fastener. In this example, middle member 800 is T-shaped in cross-section. The T-shaped cross-section is formed by a rib portion 810 and a flange portion 820 that extends laterally away from rib portion 810 on both sides of rib portion 810. While middle member 800 is shown as a T-shaped member in this example, in other examples middle member 800 has an L-shaped cross-section, a box-shaped cross-section, or another shaped cross-section. Any appropriately shaped cross-section can be used as long as it is sufficiently strong to support the drywall or other building sheet that is to be attached to framework 600.

[0057] Framework 600 has a lower member 900 that is attached to middle member 800 by a swiveling joint 806 that can be, for example, a bolt, pin, rivet, or other swiveling fastener. In this example, lower member 900 is T-shaped in cross-section. The T-shaped cross-section is formed by a rib portion 910 and a flange portion 920 that extends laterally away from rib portion 910 on both sides of rib portion 910. While lower member 900 is shown as a T-shaped member in this example, in other examples lower member 900 has an L-shaped cross-section, a box-shaped cross- section, or another shaped cross-section. Any appropriately shaped cross-section can be used as long as it is sufficiently strong to support the drywall or other building sheet that is to be attached to framework 600.

[0058] Framework 600 is only one example of a collapsible framework in accordance with embodiments of the invention. Other examples have a different number of members and/or different shape members and/or a different relative configuration of members. For example, instead of three members 700, 800, 900, Framework 600 can have two members or more than three members. In some embodiments, members 700, 800, 900 can have different relative lengths. In some embodiments, members 700, 800, 900 do not intersect at 90 degree angles. In some embodiments members 700 and 800 intersect at a first angle and members 800 and 900 intersect at a different angle.

[0059] In some embodiments, members 700, 800, 900 can be locked in a particular relative position such that they form a particular included angle relative to each other. For example, framework 600 is locked into a configuration where upper member 700 and middle member 800 form a 90 degree angle, and middle member 800 and lower member 900 form a 270 degree angle. In this example, a locking mechanism includes a first locking member 650, a pin 730 on upper member 700, and a pin 83 lon middle member 800, as well as a second locking member 670, a pin 832 on middle member 800, and a pin 930 on lower member 900. Locking members 650, 670 are rigid material such as metal, plastic or composite. Pins 730, 831, 832, 930 are a shoulder bolt configuration including a head of a diameter A, a large diameter shaft portion adjacent the head and having a diameter B that is less than diameter A, and a small diameter shaft portion adjacent to the large diameter shaft portion and having a diameter C that is less than diameter B. A detailed view of an example of locking member 650, 670 is shown in Figure 8. In this example, locking member 650, 670 has a main body 651 in which a longitudinal slot 657 is located. Longitudinal slot 657 has an enlarged area 655 at each end of slot 657 for receiving pins 730, 831. The width in the transverse direction of longitudinal slot 657 is slightly larger than the small diameter shaft portion of pins 730, 831, 832, 930, but smaller than the large diameter shaft portions of pins 730, 831, 832, 930. In this example, locking members 650, 670 are curved to act as a spring such that the ends of locking members 650, 670 are urged away from members 700, 800, 900. This urging action pushes enlarged areas 655 onto the large diameter shaft portion so that members 700, 800, 900 cannot move relative to each other due to the large diameter shaft portions not being able to pass through longitudinal slot 657. In other examples, enlarged areas 655 are a slight interference fit with the large diameter shaft portions of pins 730, 831, 832, 930 such that a user can force enlarged areas 655 of locking members 650, 670 onto the large diameter shaft portions of pins 730, 831, 832, 930 to lock locking members 650, 670 in a position that prevents relative movement of members 700, 800, 900.

[0060] Figure 7 shows frame 600 in a flat condition that can be used for shipping. Once on the jobsite, frame 600 can be folded to the desired configuration to act as a support for a soffit or other building surface. To provide the deployed configuration shown in Figure 6, upper member 700 is rotated in the direction of Arrow A to a position in which upper member 700 forms a 90 degree angle with middle member 800, and lower member 900 is rotated in the direction of Arrow B to a position in which lower member 900 forms a 270 degree angle with middle member 800.

[0061] The example shown in Figure 6 uses locking members 650, 670 of a given length that result in frame 600 having included angles of 90 degrees and 270 degrees. Using locking members of other lengths results in different angles between members 700, 800, 900.

[0062] Figure 9 shows an example where the frame 600 of Figure 7 is deployed such that upper member 700 forms a 135 degree angle with middle member 800 and middle member 800 forms a 225 degree angle with lower member 900. This configuration is the result of locking member 650 being shorter in the longitudinal direction than the locking member 650 shown in Figure 6, and locking member 670 being longer in the longitudinal direction than the locking member 670 shown in Figure 6.

[0063] Figure 10 shows an example where the frame 600 of Figure 7 is deployed such that upper member 700 forms a 45 degree angle with middle member 800 and middle member 800 forms a 315 degree angle with lower member 900. This configuration is the result of locking member 650 being longer in the longitudinal direction than the locking member 650 shown in Figure 6, and locking member 670 being shorter in the longitudinal direction than the locking member 670 shown in Figure 6.

[0064] Figure 11 shows an example where the frame 600 of Figure 7 is deployed such that upper member 700 forms a 90 degree angle with middle member 800 and middle member 800 forms a 225 degree angle with lower member 900. This configuration is the result of locking member 650 being the same length in the longitudinal direction than the locking member 650 shown in Figure 6, and locking member 670 being longer in the longitudinal direction than the locking member 670 shown in Figure 6.

[0065] Although Figures 6 and 8-11 show various deployed configurations, it is noted that any number of deployed configurations are possible using locking members of different lengths. In addition, fewer or more than three members 700, 800, 900 can be used to form different shaped structures. In some cases, a 180 degree angle can be provided between two adjacent members to for a flat section in the structure.

[0066] Figures 12-14 show another embodiment of the invention that involves collapsible members within a flat panel structure. Figure 12 shows a framework 1000 having two rigid members 1010, 1020. Rigid members 1010, 1020 are attached to each other by two collapsible members, each having a first member 1030 (also referred to as a“first portion”) and a second member 1040 (also referred to as a“second portion”). First member 1030 is pivotably attached to second member 1040 by a pin 1050 (also referred to as a“first pin” 1050). First member 1030 is pivotably attached to rigid member 1010 by a pin 1052 (also referred to as a“second pin” 1052), and second member 1040 is pivotably attached to rigid member 1020 by a pin 1054 (also referred to as a“third pin” 1054). [0067] Figure 12 is an example of framework 1000 in a collapsed state where the collapsible members are folded so that rigid members 1010 and 1020 are relatively close to each other. This collapsed state can be preferable for transport to the job site. Figure 13 shows framework 1000 is a deployed state where rigid members 1010 and 1020 are at a maximum distance apart. The state shown in Figure 13 is just one of many possible deployed states. For example, a deployed state between that shown in Figure 12 and that shown in Figure 13 can also be used. Further, the state shown in Figure 12 can be a deployed state and a state in which rigid members 1010, 1020 are closer together, or even touching, can be the collapsed state.

[0068] Figure 14 shows and example of two frameworks 1000 installed to form a soffit and facia in an occupiable space in a building having a wall W, a ceiling C, and a door D in wall W. Ceiling C makes an angle a with wall W at a comer CO. In this case the two frameworks 1000 cover comer CO with a box structure in which the two frameworks 1000 form a 90 degree angle. The two frameworks 1000 can be attached to one another and to wall W and ceiling C using screws, clips, or some other fastener. In other examples, more than two frameworks 1000 are used. In other examples, frameworks 1000 are attached to ceiling C, wall W, and/or each other at angles other than 90 degrees. In other examples, one framework 1000 is fully deployed such that first members 1030 are aligned with second members 1040, and another framework 1000 is partially deployed such that first members 1030 are not aligned with second members 1040.

[0069] While the foregoing description and drawings represent exemplary embodiments of the present disclosure, it will be understood that various additions, modifications and substitutions may be made therein without departing from the spirit and scope and range of equivalents of the accompanying claims.
