Abstract

Tube mounted bracket structure for a toolbar or similar tube with a rectangular cross section includes a bracket having a tube abutting flange with an aperture offset from an elongated slot. A rotatable insert has an inwardly directed and elongated projection conforming to the shape of the elongated slot and an aperture located at one extremity of the projection. The aperture extends through the projection and through an integral washer portion which defines an enlarged shoulder area for contacting the tube abutting flange when the insert is positioned in the slot. The elongated projection generally fills the entire slot with the exception of the aperture, thereby presenting a relatively solid bolt receiving area for mounting a U-bolt or similar bolt structure. For a toolbar or tube having relatively large cross section, the insert is positioned in the slot to provide maximum offset from the flange aperture. If the bracket is attached to a toolbar or tube with smaller cross section, the insert is rotated 180 degrees from the position for the first cross section so the projection aperture is positioned to provide minimum offset from the flange aperture.

Dependent claims

In an implement including a toolbar having a rectangular cross section with opposed faces and opposite sides, the opposite sides being spaced either a first distance or a second distance apart, the second distance being less than the first distance, adjustable bracket structure adapted for firm mounting against a selected one of the faces regardless of the spacing between the opposite sides being the first or the second distance, the adjustable bracket structure comprising:

a bracket having a flange adapted for positioning against the selected face, the flange including a flange aperture and an elongated slot offset from the flange aperture, the slot having a proximate end nearest the flange aperture and a distal end;
a slot insert including an elongated projection conforming to the elongated slot and having an insert aperture located at an end of the projection;
bracket bolt structure received by the flange aperture and insert aperture for securing the bracket against the face;
wherein the slot insert is positionable within the elongated slot with the insert aperture at either end of the slot, the distance between the insert aperture and the flange aperture being substantially equal to the first distance when the insert aperture is at the distal end and equal to the second distance when the insert aperture is at the proximate end;
and
wherein the elongated slot has rounded end portions and the protection has a partial cylindrical surface defining with one of the slot end portions a generally round aperture for receiving a portion of the bolt structure.

an angle member having a flange adapted for positioning against the selected face, the flange including an elongated slot having a proximate slot end and a distal slot end, the slot ends having a rounded configuration of preselected radius;
a slot insert including an elongated projection conforming to the elongated slot and having an integral shoulder area with an insert aperture, the insert aperture offset towards one end of the projection;
bracket bolt structure received by the insert aperture for securing the flange against the selected face;
wherein the slot insert is positionable within the elongated slot with the insert aperture offset toward one end of the slot and is rotatable with respect to the slot so the insert aperture is offset toward the opposite end of the slot to thereby adjust the location of the insert aperture relative to the toolbar to thereby adjust the angle member to the toolbar with the opposite sides being spaced either the first distance or the second distance apart;
and
wherein the elongated slot has rounded end portions and the protection has a partial cylindrical surface defining with one of the slot end portions a generally round aperture for receiving a portion of the bracket bolt structure.
