DETAILED DESCRIPTION OF THE INVENTION

[0027] Referring to FIGS. 1 and 5 of the drawings, the connector or hanger 1 of the present invention is designed to attach a supported member 2 to a supporting member 3, with the supported member 2 able to be in sloped and skewed relation to the supporting member 3. The hanger 1 has a pair of back members 4a and 4b. Side support members 6a and 6b are attached to the back members 4a and 4b. A seat member 8 attaches to side support members 6a and 6b at hinges 7a and 7b. The seat 8 has left and right seat bend lines 9 and 10. The preferred embodiment has a pair of left and right seat side members 11 and 12 extending upwardly from the seat member 8 in which the hinges 7a and 7b are formed.

[0028] Preferably, fasteners 15 are used to attach the connector 1 to the supported and supporting members 2 and 3. As shown in FIG. 3, the fasteners 15 driven through the side members 6a and 6b can be driven at an angle to make connecting in skewed orientations easier. The fasteners 15 shown are nails, but screws and other similar fasteners may be used. The connector 1 is preferably formed with a combination of round or triangular fastener openings 19 and obround or restricted slot fastener openings 20 to aid the user in positioning and driving the fasteners 15 that make the attachment.

[0029] As shown in FIGS. 1 and 3, the supported member 2 is formed with left and right sides 22 and 23 that are generally parallel to each other and are spaced apart a first selected distance 24. The supported member 2 is also formed with an end face 25 that meets with the left and right sides 22 and 23 of the supported member 2 at left and right side edges 26 and 27 of the end face 25. As shown in FIG. 1, the supported member 2 can be formed with a top face 28 and a bottom face 29 that meet with the left and right sides 22 and 23 and the end face 25. As shown in FIG. 4, the top and bottom faces 28 and 29 are generally parallel with each other and can be at a sloped angle to the generally vertically disposed end face 25. A sloping angle is an angle other than 90 degrees. The supporting member 3 has an attachment face 30 and a top face 31 that meets the attachment face 30 at a top edge 32 of the attachment face 30. As shown in FIG. 4, the attachment face 30 is generally vertically disposed and the top face 31 of the supporting member 3 is generally horizontally disposed or it can be sloped as well.

[0030] As shown in FIGS. 1 and 2, the connector 1 is formed with back members 4a and 4b. The back members 4a and 4b are substantially planar members that are formed with a vertically disposed column of elongated openings 60 to allow the back members 4a and 4b to be bent by the installer along bend lines that can be formed at the elongated openings 60. The elongated openings in each back member 4a and 4b are disposed between the outer edges of the back members 4a and 4b and where the back members 4a and 4b attach to the side members 6a and 6b. The elongated openings 60 extend in a vertical line during a typical installation as shown in FIG. 1. When the back members 4a and 4b are bent along these bend lines along the elongated openings 60, the outer portions of the back members 4a and 4b between the elongated openings 60 and the outer edges of the back members 4a and 4b are called header flanges 61a and 61b.

[0031] In the preferred connection, there is little or no contact between the left and right sides 22 and 23 of the supported member 2 and the back members 4a and 4b, and there is little or no contact between the back members 4a and 4b and the end face 25 of the supported member 2.

[0032] The back members 4a and 4b are connected to the seat member 8 only through the side members 6a and 6b.

[0033] The seat member 8 is sufficiently strong to hold the supported member 2.

[0034] As shown in FIG. 1, the back members 4a and 4b are preferably formed with a series of parallel embossments 33 sloping upwardly towards the supported member 2 from the outer edges of the back members.

[0035] The seat member 8 is preferably formed with a rectangular shape to create a bearing surface for the supported member 2.

[0036] As shown in FIG. 1, the back members 4a and 4b are attached to the side member 6a and 6b along back bend lines 37. Columns of slotted openings 51 are formed along each of the bend lines 37 to allow the back members 4a and 4b to be more easily bent with respect to the side members 6a and 6b. The embossments 33 in the back members 4a and 4b are provided between the bend lines 37 and the columns of elongated openings 60 in the back members 4a and 4b.

[0037] The connector 1 is preferably made from thin sheet steel.

[0038] As shown in FIG. 2, left and right seat side members 11 and 12 are preferably integrally connected to opposed sides of the seat member 8 at left and right seat bend lines 9 and 10 and extend generally angularly and upwardly from the seat member 8. The seat side members 11 and 12 preferably interface closely with the left and right sides 22 and 23 of the supported member 2.

[0039] The seat member 8 maybe set orthogonally from the back members 4a and 4b, or the seat member 8 maybe set at a slope.

[0040] Openings 19 and 20 for the fasteners 15 can take a variety of shapes and forms. Where fasteners 15 must be driven at an acute angle through the connector 1 into one the supported member 2 or the supporting member 3 it is preferable to form the fastener opening as an obround opening 20. In some skewed installations only the obround openings near the forward edges of the side support member 6a or 6b on the side of the connector set at an acute angle to the support member 3 will be used to attach the connector to the supported member 2. As shown in FIG. 2, these obround openings near the forward edge of the side support members 6a and 6b allow fasteners 15 to be installed when there is little room, allowing a connection to be made with fasteners 15 entering both side support members 6a and 6b and both sides of the supported member 2.

[0041] U.S. Pat. No. 4,230,416, granted to Tyrell T. Gilb teaches a restricted slot nail opening 20. In a restricted slot nail opening 20, the opening is a slot-like opening having a length greater than its width. The width of the opening is selected to register with the sides of the fastener 15 that is driven through the opening. The extended length of the opening allows the fastener to be driven at a range of angles through the opening as compared to a circular opening that is close fitting with the shank of the fastener 15. In a closely formed circular opening the fastener 15 must be driven generally orthogonally to the face of the connector 1, although generally some play is allowed and the fastener can be driven with some varying degree in its orientation. As the side support members 6a and 6b can be bent at a variety of angles to the attachment face 30 of the supporting member 3, the fasteners 15 can be driven at a variety of angles to the supporting member 3.

[0042] Bending of the side member 6a and 6b with respect to the back members 4 and 4b is facilitated by the provision of slots 51 which are aligned with one another along the longitudinally extending bend line 37 between the back member 4 and the side member 6.

[0043] FIGS. 13-15 illustrate the connector 1 skewed to the right with the acute side of the connection on the right side of FIG. 14 and the obtuse side of the connection on the left side of FIG. 14.

[0044] The retrofit connection, when the supported member 2 is already attached to the supporting member 3, is formed by inserting the connector 1 of the present invention underneath the supported member 2. The seat member 8 engages the bottom face 29 of the joist or supported member 2 and seat fasteners 15 are used to attach the seat to the supported member 2. If the connection is skewed as shown in FIGS. 13-15, before the connector 1 is put in place, the back member 6b is field bent forward at bend line 37 to engage the attachment face 30 of the supporting member 3. The hanger 1 is then put in place and fasteners 15 are driven through the back member 4b and the side member 6b through the obround openings 21 near the outer edge of the back member 4b and the forward edge of the side support member 4b to make the connection. The back member 4a is then bent back from the side support member 6a along bend line 37 and fasteners 15 are driven through the side support member 6a into the supported member 2. The back member 4a is then bent along the column of elongated openings creating the header flange 61 a that can interface with the attach surface of the supporting member 3. Fasteners 15 are then driven through the header flange 61 into the support member 3.

[0045] The connector 1 is preferably formed with attachment tabs 62a and 62b that extend from bend lines 37 above the side support members 4a and 4b. These attachment tabs make an additional connection to the upper portion of the supported member 2.

[0046] As shown in FIGS. 2, 4 and 5, the hinges 7a and 7b that connect the seat to the side members and allow the seat to pivot with respect to side members can be formed in the following manner. The seat side members 11 and 12 extend generally parallel to side support members 6a and 6b. The seat side members 11 and 12 are formed with circular openings 70 and side support members 6a and 6b are formed with corresponding circular openings 80. Preferably, the circular openings 70 are at least partially provided with one or more arcuate or annular flanges 71 which project outwardly toward the side support members 6a and 6b. If the entire opening is not circumscribed then at least a pair of opposed portions of the corresponding circular opening 70 are provided with one or more arcuate flanges 71. More preferably three or more portions of the circular opening 70 at intervals around the perimeter of the corresponding circular opening 70 are provided with one or more arculate flanges 71. Most preferably the entire opening 70 is provided with one continuous annular flange 71. To form the hinge 7a and 7b and join the members together, the annular flange of the circular opening 70 is inserted through the circular opening 80. The upper portion 72 of the annular flange 71 is then deformed to bend over an edge 82 of circular opening 80. The bent upper portion 72 of the annular flange 71 extends radially outwardly and overlies the side support members 6a and 6b, connecting the members together. The annular flange 71 has been described, according the preferred embodiment as projecting outwardly from the seat member 8. This arrangement of the members is preferred, but the annular flange 71 could be formed on the side support members 6a and 6b project toward the seat member 8.

[0047] As shown in FIGS. 1 and 3, the side support members 6a and 6b are formed with one or more embossments 86 with the one or more embossments 86 circumscribing or partially circumscribing the openings 80 in the side support members 6a and 6b. Preferably the embossments 86 are a single, continuous member that completely circumscribes the openings 80. The embossment 86 preferably projects away from the supported member 2.
