Description
- This invention relates to sheet metal framing members, such as sheet metal studs or the like. More particularly, it relates to the provision of a beaded opening in the framing member for receiving an elongated article, e.g. an electrical cable, metal or plastic conduit or the like.
- Framing walls are typically constructed from a plurality of horizontally spaced apart vertically extending studs that are connected at their upper and lower ends to horizontally extending members termed “tracks”. Some framing is constructed from wood members and other is constructed from sheet metal members. When wood members are used, it is common practice to drill a series of holes in the studs for receiving an electrical cable, water pipe, etc. that must extend through the interior of the wall of which the framing is a part. When sheet metal frame members are used for the framing, it has been the practice to stamp holes in the webs of the studs and extend the electrical cable, conduits, etc. through these holes. A problem experienced when this method is used is that the stamped openings have sharp edges that cut the electrical cable and/or conduit that is inserted through the openings. A principal object of the present invention is to eliminate this problem by eliminating the sharp edges at the periphery of the openings.
- The method of the invention comprises forming an opening in the web of a framing member then introducing a framing tool into the opening from a first side of the framing member and using said tool the metal immediately surrounding the opening, causing the flare to curve convexly from the first side of the framing member inwardly into the opening. Next, a forming tool is introduced into the flare from the second side of the framing member and used to reverse curl the flare and form it into a bead at the periphery of the opening. The bead is formed to present a convexly rounded inner surface in the opening positioned to be contacted by any object inserted into and through the opening.
- In one embodiment, the framing member is positioned on a support member that includes a punch-receiving opening. The punch is moved against the web on the side of the web opposite the support member, in alignment with the opening in the support member. Then, the punch is extended to punch an opening through the web of the frame member. After forming the opening the punch moves through the punch opening in the support member.
- In preferred form, the frame member has a channel cross section composed of the web and two flanges. The web extends between and interconnects the two flanges. The punch is introduced against the side of the web on which the flanges are located.
- In preferred form, the first forming tool is inserted into the opening from the side of the web on which the flanges are located. The second forming tool is inserted into the flare from the side of the framing member opposite the flanges.
- In preferred form, the opening formed in the web is a circular opening. The tool that is used to form the flare has a head with a first end and a circular cross sectional shape that increases in diameter from the first end as it extends axially inwardly of the tool. The tool that forms the bead has a head with the first end a circular cross section that increases in diameter as it extends from the first end axially of the tool. This flare forming tool is rotated as it is moved axially into the opening to form the flare. The bead forming tool is rotated as it is pushed axially into the flare to form the bead.
- Other objects, advantages and features of the invention will become apparent from the description of the best mode set forth below, from the drawings, from the claims and from the principles that are embodied in the specific structures that are illustrated and described.
- Like reference numerals are used to designate like parts throughout the several views of the drawing, and:
-
FIG. 1 is a fragmentary pictorial view of a region of a sheet metal stud that includes a prior art opening in which an electrical cable is received; -
FIG. 2 is a fragmentary elevational view of the stud and the electrical cable shown inFIG. 1 , taken perpendicular to the web of the stud, with the cable shown in section; -
FIG. 3 is a fragmentary sectional view taken substantially along line 3-3 ofFIG. 2 ; -
FIG. 4 is a sectional view of a sheet metal stud with its web on a support showing a circular punch moving through the web and an opening in the support member; -
FIG. 5 is a view likeFIG. 4 , but showing a forming tool being rotated and moved axially into the punched opening in the web so as to flare the opening and create a flared lip that surrounds the opening; -
FIG. 6 is a view likeFIG. 5 , showing a second tool being rotated and moved axially through the flared opening from the opposite side of the stud, for reversing the curl of the flare and forming a bead at the periphery of the opening; -
FIG. 7 is a sectional view taken through the stud at the location of a beaded opening, such view including a broken line showing of an electrical cable or other elongated member extending through the beaded opening; and -
FIG. 8 is a fragmentary pictorial view of a portion of a stud that includes two beaded openings, such view showing an electrical cable extending through one of the beaded openings. - U.S. Pat. No. 5,127,203, granted Jul. 7, 1992, to Robert F. Paquette, and U.S. Pat. No. 6,854,237, granted Feb. 15, 2005, to Matt F. Surowiecki, show framing walls composed of upper and lower, horizontal, channel members, termed “tracks”, and spaced apart, vertical studs extending between the upper and lower channel members. Both of these patents disclose wallboard sheeting secured to the opposite sides of the framing wall.
- Referring to
FIGS. 1-3 of the drawing,sheet metal studs 10 comprise aweb 12 that extends between and interconnects one set of edges of a pair offlanges flanges lips web 12 andlips flanges flanges web 12 and thelips openings 22 in the webs of thestuds 10 for receiving and accommodating anelectrical cable 24 or some other elongated member (e.g. metal or plastic tubing) which must be housed in the framing wall.FIGS. 1-3 show a prior art opening 22 which is formed by a punch. A problem with this type ofopening 22 is that the punching process leaves sharp edges at the edges of theopening 22, one of which is designated 26. Theelectrical cable 24 is fed through theopenings 22 which are usually at the same elevation in all of thestuds 10. As theelectrical cable 24 or other object is being pulled through the stampedopenings 22, its surface rides on thesharp edges 22 of theopenings 22. Quite often thesharp edges 24 cut into and damage theelectrical cable 24 or other object. - Referring to
FIG. 4 , astud 26 is shown to comprise aweb 28, a pair offlanges lips web 28 extends between and interconnects common edges of theflanges flanges lips web 28 and thelips flanges flanges web 28 and thelips FIGS. 4-6 , this gives the framing member 26 a lipped channel cross sectional shape. -
FIG. 4 shows theframing member 26 with its web against and supported by asupport member 40. A suitable tool orpunch 42 is moved against theweb 28 in alignment with a punch-receivingopening 44 formed in thissupport member 40. The punch is used to stamp or punch acircular opening 46 in theweb 28 by removing a disc shapedpiece 48 from theweb 28. Next, asuitable tool 50 is moved into the opening 46 from the open side of themember 26. Thistool 50 is used to flare theopening 46. By way of example, thetool 50 is a rotatable formingmember 52 that includes ashaft 54 that is connected to a rotary driver (not shown).Tool 52 also includes a forminghead 56 that has a formingsurface 58 shaped to flare thematerial 60 surrounding theopening 46 as the tool is rotated and moved into the opening. After theflare 60 is formed, asecond tool 62 is introduced into the flaredopening 46, from the opposite side of themember 26. By way of example, thistool 62 may be arotary forming tool 64 having ashaft 66 that is attached to a rotary driver (not shown).Tool 62 includes a shapinghead 68 which is shaped to curl the flaredportion 60 of theweb 28 so as to form it into anannular bead 60′ that surrounds the periphery of theopening 46. Thebead 60′ starts curling as it extends inwardly of the opening fromweb 28. The curling continues through theopening 46 and beyond theopening 46 so that thebead 60′ is substantially torus in shape. It is not necessary that thebead 60′ be curled as much as is illustrated inFIGS. 7 and 8 . It is only necessary that it be curled to the extent that thewire cable 24 or otherelongated object 24 will contact a rounded surface at the periphery of theopening 46. A sharp edged periphery for theopening 46 is eliminated. - The illustrated embodiments are only examples of the present invention and, therefore, are non-limitive. It is to be understood that many changes in the particular structure, materials and features that are disclosed may by made without departing from the spirit and scope of the invention. For example, the framing member may be punched and the flare formed and then the bead formed by the use of successive tools which are mounted on rollers through which the sheet metal member passes. Also, the bead may be formed on the inside of the web rather than on the outside, as illustrated. Therefore, it is my intention that my patent rights not be limited by the particular embodiments that are illustrated and described herein, but rather are to be determined by the following claims, interpreted according to accepted doctrines of patent claim interpretation, including use of the doctrine of equivalents.
