DETAILED DESCRIPTION

(15) FIG. 1 is a perspective view of a plurality of framing members 104 with a plurality of spacer members 108, according to one or more embodiments of the disclosure. Depicted in FIG. 1, framing members 104 are a plurality of roofing trusses each having a top chord 112 and bottom chord 116, and positioned adjacent to one another to form at least a portion of a structural framing for a roof of a structure 118.

(16) Spacer members 108 are positioned between each of the adjacent framing members 104 to properly space, position, and/or align each of the framing members 104 at a planned or pre-determined distance 120 from one another during erection of the structure. Described further below, in one or more embodiments the spacer members 108 are elongate members having a pair of connectors 124 that are positioned at either end thereof. Depicted in FIG. 1, connectors 124 of each of the spacer members 108 are connected to top chords 112 and bottom chords 116 of adjacent framing members 104 resulting in the spacing distance 120. As such, in various embodiments spacing distance 120 is controlled or defined by the spacing members 108 as being approximately equal to a longitudinal length of each of the spacing members 108.

(17) In addition, in one or more embodiments spacing distance 120 can vary. For example, distance 120 can be any acceptable spacing that is determined by the builder, engineer, or architect as a desirable spacing for the structure 118 being erected. As such, in various embodiments, and described further below, the longitudinal length of the spacing members 108 can vary to conform to the various building requirements of the structure 118.

(18) While framing members 104 are depicted in FIG. 1 as a plurality of roofing trusses, in various embodiments framing members 104 could be structural framing for any portion of a structure. For example, framing members 104 could include structural framing for interior/exterior walls, flooring, or other portion of the structure. In one or more embodiments framing members 104 could be constructed from various kinds of material, including but not limited to, wood, metal, polymer, concrete, or other suitable material.

(19) In addition, in certain embodiments, framing members 104 are prefabricated, such that each of the framing members 104 are fabricated at a first assembly site which is remote from a second erection site. In one or more embodiments, once fabricated, the framing members 104 can be transported to the second site by various well-known means and, once at the second site, the framing members 104 can be erected as a part of the structure 118, secured in place by various conventional means and properly spaced from the one another by the various embodiments of the disclosure. In addition, in certain embodiments spacer members 108 can be distinct from framing members 104 and attached to the framing members 104 during the erection process. In some embodiments spacer members 108 could be attached to each framing member 104 during fabrication. For example, in such embodiments, the framing members 104 could include, upon fabrication of the framing members 104, at least one spacer member 108 mounted on the top and/or bottom chords 112, 116.

(20) In such embodiments, a first end or connector 124 of spacer members 108 can be pivotally attached to the framing members 104 while a second free end or connector 124 of the spacer members 108 may be temporarily held against the framing members 104 by any suitable means. In such embodiments spacer members 108 may be rotated before erection so as to be in the position as shown in the arrangement of FIG. 1.

(21) FIGS. 2A-2C depict a spacer member 200 according to one or more embodiments of the disclosure. In various embodiments the spacer member 200 has an elongate body 204 extending between a first end portion 208 and a second end portion 212 along a lengthwise axis 216.

(22) In one or more embodiments the elongate body 204 has a main portion 220 and an offset portion 224. In various embodiments the main portion 220 has a substantially flat or planar shape, while the offset portion 224 is offset from the flat or planar shape of the main portion 220 such that the offset portion 224 defines a recess 228 on a first side 230 of the elongate body 204, depicted in FIG. 2A, and a corresponding protrusion 232 on a second side 234 of the elongate body 204, depicted in FIG. 2B.

(23) As depicted in FIGS. 2A-2C, in various embodiments the offset portion 224 defines a single continuous projection or protrusion 232 that extends along the elongate body 204 from a first protrusion end portion 236 to a second protrusion end portion 238. As such, in various embodiments, first protrusion end portion 236 presents a first protrusion end surface 240 that faces in a first direction, indicated by arrow 244 along the lengthwise axis 216, and the second protrusion end portion 238 presents a second protrusion end surface 248 that faces in a second direction, indicated by arrow 250.

(24) The protrusion end surfaces defining truss abutment surfaces and as described further below, in one or more embodiments the protrusion 232 and protrusion end surfaces 240 and 248 function to properly position and to resist undesired lateral movement of the spacer 200 by positioning the first and second protrusion end surfaces 240 and 248 adjacent to and between opposing side surfaces of adjacent framing members before and/or while the spacer 200 is fully secured in place.

(25) Referring to FIG. 7, while FIGS. 2A-2C above depict a single continuous protrusion 232, in certain embodiments a spacer 700 could include an offset portion 702 that instead defines a plurality of protrusions 704 on the second side 234 of the elongate body 204. In such embodiments, one or more of the plurality of protrusions 704 are positioned at the first end portion 208 and one or more others of the plurality of protrusions 704 are positioned at the second end portion 212 of the elongate body 204 such that the plurality of protrusions 704 continue to define the protrusion end surfaces 240, 248 for properly positioning and resisting undesired lateral movement of the spacer 700 while in use.

(26) Referring again to FIGS. 2A-2C, and referring additionally to 3A-3B, close up views of the first end portion 208 and the second end portion 212 are depicted according to one or more embodiments of the disclosure. In various embodiments the first end portion 208 includes a first connector 304 and the second end portion 212 includes a second connector 308. In various embodiments the first connector 304 is an axially extending projection 312 extending in the first direction, indicated by arrow 244, along the lengthwise axis 216 away from the elongate body 204. In such embodiments, the projection 312 includes a first projection end portion 316 that is offset from the remainder of the projection 312 by extending in a third direction, indicated by arrow 320, perpendicular to the planar shape of the main body 220 and in substantially the same direction as the offset protrusion 232.

(27) In some embodiments, and depicted in FIGS. 2A-2C, and 3A-3B, the projection additionally includes a second projection end portion 324 extending in the first direction, indicated by arrow 244, to define a substantially L shape for the end of the first connector 304, especially when viewed from the side, such as for example depicted in FIG. 2C.

(28) In various embodiments, the second connector 308 includes a pair of axially extending arms 328 extending in the second direction, indicated by arrow 250, along the lengthwise axis 216 and away from the elongate body 204. In various embodiments the pair of axially extending arms 328 are spaced apart from one another to define an axially extending space 332 or void between the arms 328. For example, depicted in FIG. 3B, the pair of axially extending arms 328 are positioned at lengthwise edges 336 of the elongate body 204 and are separated by and define the space 332. In various embodiments, the space 332 has a size or width defined by a distance 340 between each of the arms 328 such that the width of the space 332 is slightly larger than a width 342 of the projection 312 of the first connector 304. For example 0.05% to 5% larger.

(29) As such, and described further below, in various embodiments the first connector 304 can be received between the arms 328 for connecting the spacer 200 to another spacer member. In addition, in various embodiments the second connector 308 additionally includes an aperture 344. In one or more embodiments, and described further below, the aperture 344 is shaped and sized to receive the first and/or second projection end portions 316, 324 of the first connector 304 for interlocking the spacer 200 with another spacer member. For example, in one or more embodiments the spacer member 200 is configured to interlock with another spacer member by connecting the first connector 304 to the second connector 308. Specifically, in various embodiments the spacer member 200 is configured to interlock with another spacer by inserting the first projection end portion 316 of the first connector 304 of one spacer into the aperture 344 of the second connector 308 of the other spacer, such that the spacer and the other spacer are connected or held together by resisting lateral movement (e.g. movement along the lengthwise axis 216) apart from one another by the connection.

(30) In one or more embodiments, the first and second connectors 304, 308 each include one or more apertures 350 for fastening the spacer 200 a framing member. For example, depicted in FIGS. 2A-2C, 3A-3B, spacer 200 includes a plurality of apertures 350 in the form of nail holes for nailing or otherwise securing each end of the spacer to a surface of a framing member, described further below.

(31) While FIGS. 2A-2C, 3A-3B depict first connector 304 as a single projection 312 that, when in operation, is positioned between a pair of arms 328 and inserted into a single aperture 344 of the second connector 304, in certain embodiments this configuration could be reversed. For example, in some embodiments the first connector 304 could include a pair of projections 312 that, when in operation, are positioned on either side of a single axially extending arm 328 and are inserted into a pair of apertures 344 in the second connector 308.

(32) In one or more embodiments, the spacer 200 can be formed of myriad materials such as metal or alloys, resin-based materials (e.g., extruded, co-extruded, or injection molded whether basic, reaction-injection molded, or whether combined with fibers for reinforcement, etc.), composite wood or hybrid composite materials, combinations thereof, and the like. In various embodiments the materials can be tempered to enhance the structural qualities thereof or cured in the case of resin-based materials, for example. In one or more embodiments, 20 gauge (20 GA) galvanized sheet metal is used to fabricate the spacer 200, although other materials and other gauges of sheet metal can of course be used.

(33) Referring to FIGS. 4A-4G, spacing members 200 are depicted in various stages of use, according to one or more embodiments of the disclosure. Specifically, FIGS. 4A-4G depict various steps in a method of spacing a plurality of framing members 404, according to certain embodiments of the disclosure.

(34) Depicted in FIG. 4A-4B, a first spacing member 200A is first positioned between a pair of chords 408 that make up at least a portion of two adjacent framing members 404, as described above.

(35) In various embodiments each of the chords 408 of the framing members include a plurality of side surfaces including a first pair of side surfaces 412 and a second pair of opposing side surfaces 416. While the first pair of side surfaces 412 are depicted in FIGS. 4A-4G as upwardly facing, in various embodiments the first pair of side surfaces 412 includes side surfaces oriented in any direction. As such, the first pair of side surfaces 412 refers to side surfaces of the chords 408 that are generally oriented to face the same direction as one another.

(36) In various embodiments, the first spacing member 200A is positioned between the pair of chords 408 to define a gap 416, along the lengthwise axis 216, between each of the framing members 404. Specifically, in one or more embodiments the first and second connectors 304, 308 of the first and second end portion 208, 212 are placed on the first pair of side surfaces 412 such that the main portion 220 of the elongate body is substantially positioned between each of the chords 408. As such, in various embodiments a length of the main portion 220 of the elongate body defines the size of the gap 416 for positioning or spacing the framing members 404, as described above with regard to FIG. 1.

(37) In one or more embodiments the second side 234 of the spacer 200A is placed directly against the first pair of side surfaces 412. As such, in various embodiments the protrusion 232 of the spacer 200A extends outwardly from the elongate body 204 such that the protrusion 232 is positioned between each of the opposing side surfaces 416. In various embodiments, the first and second protrusion end surfaces 240 and 248 of the protrusion 232 abut the opposing side surfaces 416 of each of the chords 408. As such, in various embodiments the protrusion 232 halts or prevents movement of each of the chords 408, and as a result, each of the framing members 404, from moving closer to one another along the lengthwise axis 216. In addition, the first and second protrusion end surfaces 240 and 248 function to resist lateral movement of the spacer member 200A itself as the end surfaces 240, 248 abut the opposing side surfaces 416.

(38) In one or more embodiments, once the first spacer member 200A is in place between the chords 408, the connector portions 304 and 308 of the spacer member 200A may be fastened or secured to the chords 408. For example, depicted in FIG. 4A, each of the connector portions 304 and 308 can be nailed, via nails 420, or otherwise secured to the chords via apertures 350 in each of the connector portions 304 and 308.

(39) Depicted in FIGS. 4C-4F, once the first spacer member 200A is secured in place between the chords 408, in various embodiments a second spacer member 200B can be interlocked or connected with the first spacer member 200A to form a chain or series of connected spacer members for positioning additional framing members 404.

(40) In various embodiments, to interlock the second spacer member 200B to the first spacer member 200A, the first connector 304 of the second spacer member 200B is first at least partially inserted into the aperture 344 of the second connector 308 of the first spacer member 200A. For example, depicted in FIGS. 4C-4D, the first and/or second protrusion end portion 316 and 324 of the second spacer member 200B are generally downwardly inserted into the aperture 344 of the first spacer member 200A. Once inserted, the second spacer member 200B is rotated such that the main body 220 of the second spacer member 200B lies substantially parallel with the first spacer member 200A. Further, in various embodiments, as a result of rotating the second spacer member 200B, the second connector 308 of the second spacer 200B is generally positioned onto the side surface 412 of the additional framing member 404 to space or position the additional framing member.

(41) Further, as a result of the insertion the first connector 304 into the aperture 344 and subsequent rotation of the second spacer member 200B, the first protrusion end portion 324 abuts the edges 422 of the aperture 344 such that the first protrusion end portion 316 generally restricts or halts movement of the second spacer member 200B away from the first spacer member 200A in a lateral direction along the lengthwise axis 216. In addition, in various embodiments where the spacer member 200B includes the second protrusion end portion 324, the second protrusion end portion 324 is inserted through the aperture 344 and is rotated with the remainder of the spacer member 200B such that the second protrusion end portion 324 directly abut the second side 234 of the first spacer member 200A. In such embodiments, the second protrusion end portion 324 restricts or halts movement of the second spacer member 200B away from the first spacer member 200A in a direction perpendicular to the lengthwise axis 216.

(42) As a result of the connection of the first connector 304 to the second connector 308 of the first spacer member 200A, the first and second spacer members 200A and 200B are interlocked or connected together and form a chain 424 of spacer members that functions to space or position a plurality of framing members 404. Further, as depicted in FIGS. 4C-4G this interlocking is performed toollessly, without the use of fasteners or other devices to connect the spacer members together.

(43) In one or more embodiments, once the second spacer member 200B is in place between the chords 408, the connector portions 304 and 308 of the second spacer member 200B may additionally be fastened or secured to the chords 408. For example, depicted in FIG. 4A, each of the connector portions 304 and 308 can be nailed, via nails 420, or otherwise secured to the chords via apertures 350 in each of the connector portions 304 and 308 similarly to the first spacer member 200A depicted in FIG. 4A.

(44) Referring to FIGS. 5 and 6A-6B a plurality of spacer members 500 are depicted oriented for nesting or forming a stack 600, according to one or more embodiments. In various embodiments spacer members 500 are substantially the same as spacer member 200, described above with reference to at least 2A-2C. As such, like elements of spacer members 500 are identified with like reference numerals.

(45) In one or more embodiments, the plurality of spacer members 500 can be stacked together by aligning the offset portion 224 of each of the spacer members 500. For example, as described above, the offset portion 224 defines a recess 228 on a first side 230 of the spacer 500 and a corresponding protrusion 232 on a second side 234 of the spacer 500. In various embodiments, and depicted in FIGS. 5 and 6A-6B, each of the spacers 500 are aligned when the protrusion 232 is positioned over or with a corresponding recess 228 of an adjacent spacer member. Once aligned, the spacer members can be stacked by moving the plurality of spacer members 500 together such that the protrusion 232 of the spacer member 500 nests into a corresponding recess 228 to form the stack 600, such as depicted in FIG. 6B.

(46) Referring to FIGS. 8-10, a spacer member 708 with a downwardly flared lengthwise edge portion 720 is depicted. Such additional structure providing an additional pair of lengthwise corners or bends 724 provide enhanced strength with respect to bending or buckling. Illustrative dimensions, in inches, are provided that are also applicable to other embodiments enclosed herein. A set of like spacers with the given dimensions would provide proper spacing for 24 inch on-center truss or other structural lumber arrangement with the holes 728, 729, suitable for nails, located precisely 24 inches apart. In embodiments, other acceptable truss spacings of 12 inches, or 16 inches, or 30 inches. The length dimensions control the structural member spacing and are thus much more critical than the width dimensions.
