Rionda and Joaquim Jack Palacio as the inventors and which is assigned to the assignee of the present invention discloses a truss hanger which may be used for attaching trusses to w ~den beams running transverse to the longitudinal axis of the truss.
BAC~GROU.~ OF THE INVENTION
The present lnvention relates to wooden trusses used for supporting structural loads and to har~ware used in constructing wooden trusses whirh enhances the ease of instal-lation and increases the resultant structural rigidity of the installed trusses for bearing structural loads.
DESCRIPTION OF THE PRIOR ARTIn construc~ing various types o wooden truss il assemblies, including both roo~ trusses and floor joists, it has been common to use large wooden s~ructural members such as 2" x l~"s. Such large wooden members, however, are becoming increasingly difficult to obtain and have increased in cost substantially. Consequently, various alternatives have been sought for enabling the construction of trusses which are able to bear the structural loads of full dimension lumber but which are constructed from smaller pieces of dimension lumber such as 2" x 4" members which are spaced apart by metal connectors.
Substitutes for full dimension lumber roof trusses and floor joists must satisfy two primary criteria. First, the trusses must be able to withstand large compressive loads so that they may be used for bearing substantial structural loads. Second, it is desirable that the trusses be prefabricated at a manufacturing plant at a low labor cost and shipped to a building site without a high degree of risk of incurring damage to the trusses.
Various types of hardware have been developed ~or making prefabricated trusses. United States Patents 3,025,577 to Jureit, 3,298,151 to Jureit, and 4,07~,352 to Knowles, and United States Patent No. 4, 485, 606 entitled "Truss Structures Constructed with Metal Web Members"
which names Robert Gottlieb as the inventor and which is assigned to assignee of the present invention discloses the preferred type of metal connector to be used in fabricating truss assemblies in conjunction with the truss hanger and connector hanger of the present invention.
Trusses have been installed at the building site in a number of ways. If the trusses are being used to construct a floor, they may be laid on top of the foundation walls and nailed into a beam which extends perpendicular to the longitudinal axis of the trusses. The trusses have been nailed in place by toenailing through various surfaces of the wood at the end of the truss.
SUMMARY OF TH~ IN~NTION
It is an objec~ of the invention to provide a hanger ~or attaching trusses to beams running transverse to the longitudinal axis of the trusses which does not require the extensive use of the attachment elements through the wooden members of the individual trusses.
The hanger for trusses provides a mechanism for attaching the trusses fixedly to a beam running perpen-dicular to the longitudinal axis of the individual trusses which eliminates the need for using toenailing or types of connection mechanisms which require the extensive use of fasteners. Normally, a pair of "left and right" hangers is attached to both ends of each truss to provide a bracket which may be laid over the top of the beam and fastened to the beam without the use of extensive labor.
The hanger for trusses provides a mechanism for fixedly attaching the ends of a truss directly to a beam running transverse to the longitudinal axes of the truss by means of nailing a strap directly to the surface of the beam.
A hanger for trusses in accordance with the invention includes a bracket having a first leg disposed in a first plane with first and second ends and two outside edges running between the first and second ends, the first leg having a side which is adapted to engage the width of beam, a base, disposed in a second plane, having first and second ends, the first end of the base being attached to the first end of the leg at approximately a 90 angle, the base being adapted to engage the top of the beam, a second leg~ disposed in a third plane which is parallel to the second plane, and ,1 is attached to the second end of the base at an approximate 90~ angle, the second leg being adapted to engage a second side o~ the bea~ across its wicl~h; and a connec~ing plate disposed in a fourth plane, the connecting plate being attached to the first leg along one of outside edges, the fourth plane being substantially perpendicular to the first plane, the connecting plate having a plurality of sharp projections extending generally perpendicular from the connecting plate toward the other outside edge. The hanger further includes at least one aperture in the base and second leg which is adapted to receive nails for attaching the beam to the bracket.
A connector hanger in accordance with the invention includes a connecting plate having a plurality of sharp projections extending generally perpendicular from the connecting plate, the connecting plate being disposed in a first plane and having a plurality of outside edges; a strap disposed in a second plane which i~s joined to one of the outside edge of the connecting plate, the second plane being substantially perpendicular to the first plane, the strap having a plurality of apertures adapted for receiving nails and extending the entire length of the edge of the connecting plate to which the strap is joined and projecting past the connecting to provide a surface for nailing the strap to a wooden member;
the strap being rectangular in shape and being joined to the connecting plate along one of its ~wo longest sides with the end of the longest side being coterminous with the end of the outside edge of the connecting plate to which the strap is attached and the sharp projections extending toward the other o~ the two longest sides.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Figure 1 illustrates an end view of a truss assembly which uses a hanger 10 in accordance with the invention.
The truss 1~ has an upper wooden member 14 and a lower wooden member 16 which may be made from standard dimension lumber such as a ~" x 4" which is turned on its side so that the width of each 2" x 4" within the truss is parallel to the horizontal. The upper wooden member 14 and the lower wooden member 16 are fixedly attached to a plurality of metal web members 18 which may be of any known construction but which preferably are those which are described in the aforementioned U.S. Patent No. 4,485,606. Each of the metal web members l~ has three connecting plates 20 which have a plurality of sharp teethlike projections which are pressed into the wooden members 14 and 16 to completely embed the projections into ~he wood to securely attach the metal web member into the upper and lower wooden members. ~hile the design of the sharp teeth like projections is not part 67~3 of the present invention, preferably they are manufactured in accordance with ~he teachings of United States Patent No. 4,343,580 which is owned by the assignee of the present invention. A pair of intermediate sections 22 connects the connecting plate 20 at the vertex with the connecting plates at the ends. Each truss 12 is supported at its ends 24 by a pair of truss end supporting beams 26 which run transverse to the longitudinal axis of the trusses. While it is common practice to support trusses with wooden beams in modern construc-tion, it should be clearly understood that the truss hanger is not limited to the use of wooden truss end supporting beams and in fact may be used with any truss end supporting structure having a rectilinear cross-sectlon. The truss hanger lO is used to attach the truss 12 to the truss end supporting beam 26. The truss hanger is described in detail infra in conjunction with Figure 4.
Figure 2 illustrates an end view of a truss having a construction identical to that described supra in Figure l except that a connector hanger 70 is used to attach the truss 12 to the truss end supporting beams 26 instead of the truss , hanger lO of Figure l. Identical parts in Figures l and 2 are ldentified by like reference numerals. The connector hanger 70 has a connecting plate 72 having a plurality of teeth like projections which are embedded in the lower wooden member 16 and a strap 74 which is nailed into the truss end supporting beam 26. The connector hanger 70 is described in detail infra in conjunction with Figure 5. The connector hanger 70 is an alternative to the hanger lO for attaching a truss 12 to a truss end supporting beam 26.
Figure ~ illustrates the preferred form of using , hangers l0 in accordance with the invention. A pair of "left and right" hangers 10 are attached to both sides 27 of the upper wooden member 14. In a like manner, the connector hanger 70 is preferra~ly attached to both sides 29 of the lower wooden member 16. Only one side 29 is illustrated Figure 3.
Figure 4 illustrates an isometric view of a truss hanger 10 in accordance with the invention. The truss hanger 10 has a bracket ~0 having a first leg 8~ disposed in a first plane with a first end ~4 and a second end 86 and two outside edges 8~ running between the first and second ends. The first leg 82 has a side 90 which is adapted to engage the width of a truss end supporting beam ~6 (Figure l).
A base 9~, which is disposed in a second plane substantially perpendicular to the first plane, is attached to the first leg 82. The first end 84 of the first leg 8~ is joined to the base Y2 at the first end 94 o~ the base. The base is adapted to engage the top of thhe truss end supporting beam 26 (Figure 1). A second leg 96, disposed in a third plane, is joined to the second end Y8 of the base 92 at a substantially 90 angle. The second leg 98 has a surface 100 which is adapted to engage the second side of the truss end supporting beam.
The base 92 and second leg 98 has a plurality of apertures 102 which are adapted for receiving nails for securing the truss hanger l0 to the truss end supporting beam 26. A connect-ing plate 104, which is disposed in a fourth plane, is joined to the first leg ~2. The connecting plate 104 is joined along one of its outside edges 106 to one of the outside edges 88 of th~ first leg 82. The fourth plane for~ls an approximate 90 angle with the first plane. The connecting ;~ plate 104 as a plurality of teeth-like projections 108 which !l extend substantially perpendicular from the fourth plane toward the remaining edge 88, l~hile the truss hanger 10 is preferrably used for attaching trusses to truss end supporting beams 26, it should be clearly ~mderstood that its use to attach trusses to truss end supporting beams is not a limitation to its field of use.
Figure 5 illustrates an isometric view of a connector hanger 70 in accordance with the invention. The connecting plate 72 has a plurality of sharp teeth like projections 120 extending generally perpendicular from the plane of the connecting plate. The connecting plate 72 is preferrably rectilinear in shape and has four outside edges 122. A strap 74 is joined to one of the outsid~ edges 122, The strap is disposed in a second plane which orthogonal to the first plane. The strap 124 extends from the first end 12~ of the outside edge 122 to which it is attached completely along the outside edge past the other end 128 of the outside edge.
The amount of extension of the strap 124 past the end 128 is not critical and generally should in combination with the connecting plate equal the width of the truss 12 (Figure 1~.
The strap 124 has a plurality of apertures 130 which are adapted for receiving nails for securing the strap to the truss end supporting beam ~6 (Figure 1). The strap is preferrably rectilinear in shape with one of the two longest sides 132 being joined to the connecting plate 72 as previously described. The sharp teeth like projections 121 project from the plane of the connecting plate 72 toward the other longest side 132 to which the connecting plate is not joined.
~ ile the invention has been described in terms of its preferred embodiments, it should clearly be understood _g_ that numerous modiflcations may be made to the invention without departing from its spirit and scope as defined in the appended claims.

The truss hanger 10 has a bracket ~0 having a first leg 8~ disposed in a first plane with a first end ~4 and a second end 86 and two outside edges 8~ running between the first and second ends. The first leg 82 has a side 90 which is adapted to engage the width of a truss end supporting beam ~6 (Figure l).
A base 9~, which is disposed in a second plane substantially perpendicular to the first plane, is attached to the first leg 82. The first end 84 of the first leg 8~ is joined to the base Y2 at the first end 94 o~ the base. The base is adapted to engage the top of thhe truss end supporting beam 26 (Figure 1). A second leg 96, disposed in a third plane, is joined to the second end Y8 of the base 92 at a substantially 90 angle. The second leg 98 has a surface 100 which is adapted to engage the second side of the truss end supporting beam.
The base 92 and second leg 98 has a plurality of apertures 102 which are adapted for receiving nails for securing the truss hanger l0 to the truss end supporting beam 26. A connect-ing plate 104, which is disposed in a fourth plane, is joined to the first leg ~2. The connecting plate 104 is joined along one of its outside edges 106 to one of the outside edges 88 of th~ first leg 82. The fourth plane for~ls an approximate 90 angle with the first plane. The connecting ;~ plate 104 as a plurality of teeth-like projections 108 which !l extend substantially perpendicular from the fourth plane toward the remaining edge 88, l~hile the truss hanger 10 is preferrably used for attaching trusses to truss end supporting beams 26, it should be clearly ~mderstood that its use to attach trusses to truss end supporting beams is not a limitation to its field of use.
Figure 5 illustrates an isometric view of a connector hanger 70 in accordance with the invention. The connecting plate 72 has a plurality of sharp teeth like projections 120 extending generally perpendicular from the plane of the connecting plate. The connecting plate 72 is preferrably rectilinear in shape and has four outside edges 122. A strap 74 is joined to one of the outsid~ edges 122, The strap is disposed in a second plane which orthogonal to the first plane. The strap 124 extends from the first end 12~ of the outside edge 122 to which it is attached completely along the outside edge past the other end 128 of the outside edge.
The amount of extension of the strap 124 past the end 128 is not critical and generally should in combination with the connecting plate equal the width of the truss 12 (Figure 1~.
The strap 124 has a plurality of apertures 130 which are adapted for receiving nails for securing the strap to the truss end supporting beam ~6 (Figure 1). The strap is preferrably rectilinear in shape with one of the two longest sides 132 being joined to the connecting plate 72 as previously described. The sharp teeth like projections 121 project from the plane of the connecting plate 72 toward the other longest side 132 to which the connecting plate is not joined.
~ ile the invention has been described in terms of its preferred embodiments, it should clearly be understood _g_ that numerous modiflcations may be made to the invention without departing from its spirit and scope as defined in the appended claims.
