Abstract
A connector is provided to attach a supported member to a supporting member, with the supported member being in sloped and skewed relation to the supporting member. The hanger has left and right back members and left and right side support members attached to the left and right back members respectively. A seat member attaches to both the left and right back members along aligned left and right seat bend lines. A pair of seat side members can extend from the seat member. A pair of left and right jutting tabs extend from the left and right back members respectively.

12. The connection of claim 1, wherein: a fastener is driven through the seat member and into the bottom face of the supported member.
13. The connection of claim 1, wherein: the left and right side support members that extend from the left and right back members are attached to the back members at outer side edges of the left and right back members, the outer side edges being located away from the left and right side edges of the end face of the supported member.
14. The connection of claim 2, wherein: a. the left side support member that is attached to the left back member extends from a side of the left back member opposed to a side of the back member to which the left jutting tab attaches; and b. the right side support member that is attached to the right back member extends from a side of the right back member opposed to a side of the back member to which the right jutting tab attaches.

(19) The seat member 8 may be set orthogonally from the back members 4 and 5, or the seat member 8 may slope upwardly or downwardly from 90 degrees. In some installations, the upward slope may be up to 49 degrees with very little loss in load capacity. In some installations, the hanger 1 can accommodate any upward slope to 45 degrees without a change in the allowable loads for the hanger. In some installations, between 45 degrees and 49 degrees, the allowable loads for the hanger 1 are slightly reduced. Similarly, in some installations, the downward slope may be as much as 49 degrees with only slight reduction in load capacity and with no difference in allowable loads up to slopes of 45 degrees downward.

(21) Openings 19, 20 and 21 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 or both of the supported member 2 and the supporting member 3 it is preferable to form the fastener opening with a fastener guide 21 or other opening that helps direct the fastener 15 at the proper acute angle.
(22) 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. As shown in
(23) U.S. Pat. No. 4,291,996, granted to Tyrell T. Gilb teaches a modified restricted slot nail opening that can guide a fastener 15 at a particular angle. Gilb called it a positive nail angling device. The positive nail angling device starts with a restricted slot nail opening. The width of the opening is selected to register with the sides of the fastener that is driven 15 through the opening. A tab-like member is formed from the displaced material from the slot-like opening and bent along a bend line which constitutes one end of the slit-like opening. The opening has an opposite end from the end from which the tab-like member is bent. The tab-like member is formed with a nail receiving surface for positively receiving a side of the fastener shank 16 in generally parallel, face to face relationship. The length of the slot-like opening and the displacement angle of the tab-like member are selected so that the fastener can only be driven at a pre-selected angle through the opening. One side of the shank 16 of the fastener 15 is in close fitting relation to the opposite end of the slot-like opening and the opposite side of the shank 16 of the fastener 15 is in touching or close fitting relation to the receiving surface of the tab-like member. If the tab is undisturbed, the fastener 15 can only be driven at a slant angle to the face of the connector 1.
(24) U.S. Pat. No. 5,603,580, the specification of which is hereby incorporated by reference, granted to Leek and Commins teaches a fastener guide 21 or guideway somewhat similar to Gilb '996. The positive angle fastener device of Leek '580 taught forming a fastener guide 21 by making a slit cut in the material of the connector 1 and then bending the material at the slit cut to form a half-cone like shape for receiving and holding a fastener 15 at a selected angle while the fastener 15 is being driven. As shown in

(27) 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 supported member 2 is inserted between the jutting tabs 13 and 14 and the back members 4 and 5 of the present invention. The seat member 8 is then field bent to engage the bottom face 29 of the joist or supported member 2. If the connection is not skewed, the back members 4 and 5 are set to engage the attachment face 30 of the supporting member 3 and fasteners 15 are driven through the jutting tabs 13 and 14, the side support members 6 and 7 and the seat member 8 to make the connection. If the connection is skewed, the side support members 6 and 7 are field bent. The side support member 6 or 7 on the side of the connection where an acute angle is formed between the supported member 2 and the supporting member 3 is bent to interface and register in parallel relation with the attachment face 30 of the supporting member 3. On the opposite side, the side support member 26 or 7 is bent to contact the attachment face 30 of the supporting member 3. Fasteners 15 are then driven through the side support member members 6 and 7, the jutting tabs 13 and 14 and the seat member 8 to make the connection.
