Description

TECHNICAL FIELD

This invention relates to apparatus employed in the building construction industry and more particularly to apparatus for stabilizing a suspended channel member of the type employed, for example, to hold or support pipes, conduits or other components of a building from building structure.

BACKGROUND OF THE INVENTION

Channel members or struts are commonly employed in the building construction industry for a variety of purposes. Channel members are commonly used, for example, with hanger rods, and the channel member depending from the hanger rod is routinely employed to hold or support pipes, conduits or other components of a building from a ceiling or other overhead building structure.

The typical channel member is of elongated construction and includes a channel member base and two spaced, substantially parallel channel member legs attached to the channel member base and extending therefrom. Each of the channel member legs has an inturned lip extending over an interior of the channel defined by the channel member base and the channel member legs. The channel member has two ends defining openings communicating with the channel member interior.

Many different types of hardware or fittings have been devised for use with channel members to accomplish specific objectives. Some of these devices are attached at the ends of a channel member to accomplish such tasks as that of securing the channel member to a beam or other support. Representative examples of fittings are shown, for example, on pages 83 and 87 of the Power-Strut Engineering.Catalog, Copyright 1987, 1992, 1994, made available by Grinnell Corporation, and on pages 84, 86 and 90 of the B-Line Strut Systems Engineering Catalog (BL2R), Copyright 1985 by B-Line Systems, Inc.

It is also known to attach end caps to the ends of channel members for such purposes as to provide a decorative appearance or to prevent concrete from entering the channel member during a concrete pour. Representative ends caps are shown on page 108 of the Power-Strut Catalog indicated above and on page 87 of the B-Line Strut Systems Engineering Catalog noted above. Simple end caps are slipped over channel member ends to function as protective safety covers.

Page 108 of the Power-Strut Engineering Catalog shows a short anchor end cap which functions as a concrete insert that is positioned at an end of a channel member to block concrete from entering the end of the channel member and to provide an outwardly projecting anchor which extends upwardly through the concrete. In other words, the channel member and the short anchor end cap are positioned in situ together and are maintained together as a unit after the concrete has been poured and hardened. There is no fastener means employed in such an arrangement for allowing the short anchor end cap to function with a suspended strut or channel member to stabilize same. The type ‘B’ end cap shown on the same catalog page is utilized in much the same manner as the short anchor end cap.

None of the prior art fittings is for the purpose of, or suitable for, stabilizing a suspended channel member and restricting movement of the suspended channel member from a location at the end of the channel member. With conventional arrangements, stabilizing structure is connected to a channel member at a location or locations between the ends thereof. This will result in an inability to utilize the maximum effective length of the channel member as a support for support pipes, conduits or other components of a building, as well as interfere with installation of these components on the channel member.

DISCLOSURE OF THE INVENTION

My co-pending U.S. patent application Ser. No. 09/841,647, filed Apr. 24, 2001, indicated above, of which the present application is a continuation-in-part, relates to an approach for bracing a suspended channel member against movement due to earthquakes and the like while enabling the user to employ the full length of the channel member to provide support for pipes, conduits or other components of a building. The present invention relates to another approach for accomplishing this objective.

The present invention encompasses a combination including an elongated channel member having a channel member base and first and second spaced, substantially parallel channel member legs attached to the channel member base and extending therefrom. Each of the channel member legs has an inturned lip extending over a channel member interior defined by the channel member base and the channel member legs.

An attachment member is connected to the channel member. The attachment member is comprised of a plurality of attachment member plates secured together and located at the channel member end.

At least some of the attachment member plates are angularly disposed relative to one another with a first attachment member plate in engagement with the channel member and a second attachment member plate projecting outwardly from the channel member for attaching stabilizing structure to the channel member when the channel member is suspended to stabilize and restrict movement of the suspended channel member.

Other features, advantages and objects of the present invention will become apparent with reference to the following description and accompanying drawings.

The channel member 30 is of conventional construction.and includes a channel member base 32 having two channel member legs 34 , 36 attached thereto and extending therefrom. Each of the channel member legs has an inturned lip 38 extending over the interior of the channel member defined by the base 32 and legs 34 , 36 . The ends of the channel member, including the end at which the attachment member 10 is positioned, are open and communicate with the channel member interior.

FIG. 2 shows the channel member 30 .supported by a threaded hanger rod 40 in a conventional manner. In the arrangement illustrated, the hanger rod 40 passes through the channel member and through a rectangular-shaped washer 42 disposed above the channel member. Also as is conventional, a nut 44 engages a washer 42 . Another nut (not shown) is threadedly engaged with the lower end of the hanger rod to secure the hanger rod in position relative to the channel member.

When the attachment member 10 is in the position shown in FIGS. 2 , 3 and 4 , the plate 12 is in engagement with the channel member and disposed parallel and closely adjacent to channel member leg 36 . The plate 12 is positioned under the inturned lip 38 thereof for limiting upward movement of the plate 12 relative to the channel member. Also, since the upper end of plate 12 is disposed in the recess defined by the lip and channel member leg it is captured therein and cannot tilt relative to the channel member leg.

Plate 14 extends from the plate 12 to a location under the inturned lip 38 of channel member leg 34 to restrict relative movement between the third attachment member plate and the channel member. In other words, with the arrangement illustrated, the upper ends of both plates 12 and 14 .have their movement restricted by the lips 38 of the channel member. Preferably, the plates 12 and 14 are sized and configured to lockingly engage with the channel member when engaging their respective lips 38 .

FIG. 2 shows stabilizing structure in the form of wire braces 50 attached to plates 12 and 18 at holes 22 , 24 thereof. The distal ends of the wire braces form loops and are wrapped about the straight segments of the wire braces. The upper ends of the braces project to a ceiling or other overhead building structure (not shown).

In the embodiment of FIGS. 1-4 , fastener means is employed to more positively fasten the attachment member to the channel member. This fastener means is in the form of a self-drilling tapping screw which is threadedly engaged with the channel member and is in locking engagement with plate 12 . FIG. 2 shows the screw 48 prior to application thereof, a dash line representation being made of the area of plate 12 which receives the screw.
