Abstract: A bar hanger having an elongated head and an elongated tail extending downwardly from the head. The tail has a first portion normal to the head, a second portion inclined relatively to the first portion, and a third portion inclined relatively to the second portion so that the first and second portions are parallel. The third portion has a free end with a threaded connecting element. The tail and the head lie substantially in a common plane and may be slipped through the space between a pair of elongated chords of a building joist such that the head is above the tops of the chords. The hanger may then be rotated 90.degree. so that the head rests on both chords and the free end of the third portion is off-set from the space between the chords for attachment to a conduit hanger so that the conduit can be carried by the joist. The bar hanger permits rapid installation of the conduit hangers and spreads the load over both chords.

The device also includes a clip constituting the outboard end of the device and coupled to the screw for being positively fastened to the pegboard by the screw.

Abstract: A fastening element with an adjustment flange and an eccentric segment for objects to be suspended as, in particular, heating elements or convectors, which engages into bores of an attachment wall and a rear wall of the object lying opposite each other, has between an outer adjustment flange and an inner flange an adjustment eccentric clamped eccentrically with respect to the flanges for compensation of alignment errors of the bores, whereby the surface of the inner flange facing away from the eccentric comes to rest against the attachment wall externally of the bore receiving a bolt and the adjustment eccentric slid loosely upon the bolt is arranged only in the area of the bore of the rear wall to be pivotable around the bolt from outside of the bore.

Abstract: A device for engaging and holding an article, such as a wood log, to facilitate moving the same, includes a bolt with a point that may be modified to a smaller than standard conical angle, the point having runout threads thereon, and a handle rigidly secured to the bolt at a location spaced axially from the point and projecting laterally from the bolt axis. A user can wield the device by the handle to strike the article with the point to cause the point to penetrate the article, following which the user can rotate the handle about the bolt axis to force the bolt thread into threaded engagement with the article. The device also has a shackle rigidly secured to the handle at a location in line with the bolt axis with the bolt and the shackle extending in opposite directions from the handle, so that the shackle can be grasped to move the article with the bolt in threaded engagement therewith.

In another embodiment, bumper engaging hangers are provided for use on box type bumpers as well as covered bumpers.

Abstract: A structure serving for use in the tie-down of cargo on the bed of a truck characterized by a body member, partly threaded both externally and internally, which has been inserted into a hole drilled through the truck bed, and a further assembly including both a positioning or plug member and a nut disposed beneath the truck bed and threadedly secured to external threads on the stem of the body member. The head of the body member and the positioning member each have complementary outwardly flaring surfaces, so that, when drawn together by wrench means, the top surface of the body member is in a generally flush relationship with the surface of the truck bed adjacent the hole. The internal threads of the body member typically receive an eyehook, which, in turn, receives a rope or the like for positioning the cargo on the bed of the truck.

Abstract: An adapter which converts a bolt into a hookbolt has a nose portion and a tail portion diametrically opposed with respect to the stem of the bolt. The nose portion has an engagement surface which curves upwardly away from a flange to which the bolt is to be hooked, and parallel ribs are provided on the engagement surface which extend outwardly away from the stem of the bolt. The ribs are deformable so as to compensate for irregularities in the surface of the flange.

Abstract: A hollow wall fastener using a conventional toggle bolt and a toggle anchor which is pointed and which has an open groove for receiving the toggle bolt. An end cap within the anchor has an internally threaded head portion and a frangible portion which allows the head portion to separate from the rest of the end cap when the end of the bolt is threaded into the head portion, thus twisting the frangible portion until it breaks. Thereafter the head portion prevents withdrawal of the toggle bolt from the anchor. The end of the groove has a threaded portion which cooperates with a threaded portion of an aperture opposite the groove to permit the anchor to pivot with respect to the bolt to a position where the bolt is threadably engaged and locked in the threaded portions of the anchor, forming a "T" configuration behind the surface of the hollow wall. Thereafter the bolt may be rotated to draw the anchor tightly against the interior of the hollow wall.
