An adjustable hanger bracket and bracket assembly for tubular members. The assembly includes a longitudinally extendable span member arranged to be fastened to facing sides of laterally spaced supporting members, such as horizontally disposed joists or vertically positioned wall studs. Longitudinally adjustable brackets slidably engage the external surface of the slidably adjustable span member to support tubing or piping sections which may be positioned between adjacent studs or joists.

1. Field of the Invention
The present invention relates to a device having special application for supporting flexible PEX (cross-linked polyethylene), or copper tubing, used in radiant heating installations, as well as for stubbing out copper tubing supplying hot and cold water for kitchen and bathroom usage.
2. Background Information
It is usual to provide supporting brackets for PEX or copper tubing for supplying heated radiant heat applications under floors and within walls of buildings, as well as for stubbing out copper tubing used in hot or cold supply lines while positioned in the area between floor joists of a building, or between wall studs. In the latter case, such tubing is often used for supplying hot and/or cold water from a source to various lavatory, toilet or other fixtures used in commercial lavatories and in home bathrooms and kitchens. It is essential, particularly in radiant heating, to maintain the spatial distance from the tube carrying heated water or other liquids to the under flooring and to be able to control the temperature in a particular room. This often requires tedious manual adjustment of wire twists and wire ties and brackets for securing the tubing to a hanger bracket at a relatively fixed distance from the flooring or wallboard. Such actions require a great deal of manual manipulation and tying of wire ties and the like.
In addition, components of previous brackets have generally been fixed in dimension, which required additional manipulation, cutting, soldering or welding to insure proper dimension between supporting members, such as floor joists and vertical studs. Generally the spacing between studs and joists is governed by local codes. However, over time, these codified dimensions may vary. Consequently, there is a need for an adjustable pipe or tubing supporting bracket, and one that is easy to install and adjust to suitable dimension. This is particularly true in the case of fluid transporting tubing or piping requiring long stretches and bends in radiant heating installations. In addition, the spacing between such tubing or piping is specified by local codes. Thus, the need for adjustable assemblies has become quite prevalent over the years. Consequently, there is need for an adjustable pipe or tubing hanging member that is easy to install and provides secure fastening of tubing or other fluid transporting devices. This is particularly true in overhead installation of tubing or piping.
The present invention is directed to an adjustable hanger bracket member for supporting flexible PEX tubing or copper pipe or the like. The adjustable bracket assembly has particular application for use in supporting tubing or piping between floor joists and spacing between upstanding wall stud members, which spacing may vary over time in use
The adjustable hanger bracket assembly of this invention comprises a generally linear, longitudinally adjustable, supporting span member. The longitudinal bracket adjustment is provided by means of at least two elongated span members maintained in slidable “nesting” arrangement. Both bracket segments are preferably formed from sheet metal stamped, extruded, or otherwise bent to a predetermined configuration. Each segment preferably includes an elongated base portion, which is substantially planar along its longitudinal axis, and which is further defined to have an outwardly angular bend at both of the parallel sides to provide oppositely spaced, coextensive apron portions of fixed width along the longitudinal axis of the adjustable span member.
The segments are each of similar cross-section with the top section overlaying the under segment to provide slidable longitudinal adjustment of the nested span segments to accommodate dimensional variations in the spacing between stationary support members, such as the adjacent joists or studs. The segments are restrained from separation by means of a laterally extending marginal edge portion of the overlaying top segment being bent inwardly to wrap around the underlying marginal edge portion of the under segment of the span member.
Further adjustability of the bracket assembly may be achieved with the addition of one or more longitudinally adjustable pipe clamps slidably secured to the uppermost segment of the span member. The pipe clamps are preferably formed to receive and retain either PEX, plastic tubing, or copper pipe or the like. In a preferred form, each of the clamps is molded of a resilient material, such as commercially available ABS white #740. (ABS is a plastic molding material having the generic name Acrylonitrile-Butadiene-Styrene and obtained from multiple sources listed in the current Plastics Encyclopedia published by McGraw Hill of Heights Town, N.J.).
The clamps are integrally formed with a supporting base portion with an oppositely extending clamping arms. One set of bifurcated clamping arms is formed to provide inwardly facing surfaces, preferably dimensioned to embrace the outer, exposed surface of the span member. The base portion of each clamp further encloses oppositely extending, bifurcated clamping arms each cooperating to provide inwardly facing clamping surfaces for resiliently embracing a respective tubing or piping member. Each of the integrally formed, bifurcated arms are provided with retaining portions permitting “snap action” during entry and retention of a respective pipe or tubing. Each clamp is further designed to provide longitudinal adjustment relative to the span member, and may be positioned on the span member, either before or after securing the span member to the adjacent joists or stud members. It will be apparent that facile installation of the bracket assembly has been greatly simplified by means of this assembly. The entire installation, except for applying fasteners for mounting to adjacent joists and studs, may be accomplished with manual manipulation of parts. There is no need of spring-like devices requiring special tools or soldering, each of which entails extra time for installation labor. The novel assembly includes a readily adjustable supporting span member with added versatility with installation.
As will be apparent from the following detailed description, the present assembly may have a multitude of applications, and also may be modified, for instance, to be secured by use of pointed, arrow-like projections (not shown) designed to penetrate into the fibers of wood support members, such as joists or studs.

The tubings 26 are adjustably separable and supported by pipe clamps 32, slidably received and movable relative to the span segments 14 and 16 before or after assembly to upstanding, spaced apart, stud members 28 (see

The foregoing is considered as illustrative only of the principles of the invention. Furthermore, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described. While the preferred embodiment has been described, the details may be changed without departing from the invention, which is defined by the claims.
