ADJUSTABLE TWO-PIECE CLIP FOR MOUNTING
OBJECTS ON A WALL STUD
S
Cross-Reference To Related A~nlications This application claims priority under 35 U.S.C. ~119(e) to provisional patent application serial number 60/132,667 filed May 5, 1999, entitled "Two-Piece Clip For Attachment To Metal Stud," the entire disclosure of which is incorporated herein by reference.
Field of the Invention The present invention relates generally to the art of support clips and brackets and, more particularly, to such clips or brackets for mounting devices, equipment or the like on 1 S wall studs. In even greater particularity, the present invention is directed to a two-piece sheet metal clip for mounting electrical boxes and other objects on metal or wood wall studs, one piece of the clip including at least one support member which engages the webbing of the stud to provide support for the box against inward flexing of the clip when force is applied inward of the box.
Background of the Invention In mounting electrical boxes or the like on wall studs, it is desirable to provide support to the electrical box to counter any flexing of the mounting means experienced as a result of inward force on the box. Moreover, it is also desirable to be able to adjust the position of the box according to the thickness of drywall being used. Some designs typically omit the extra needed support altogether and are not adjustable.
Also, some designs incorporate a looping design which causes the clip to be more flimsy.
These drawbacks can be extremely frustrating when attempting to complete electrical connections in the field. Accordingly, in view of the foregoing drawbacks with currently available clips, an improved adjustable clip for mounting objects on a wall stud is needed to overcome difficulties in support during installation and to provide benefits of costs and reliability.

Detailed Description Referring to the drawings, a representative two-piece sheet metal clip for mounting an electrical box B and other objects on metal SM or wood SW wall studs, embodying various features the present invention, is generally indicated throughout the figures by reference character 10. Electrical box B is of a conventional type, and includes a generally rectangular peripheral side wall 11 having an open front end 12, and a rear end that is closed by a rear wall 13. The metal wall stud SM illustrated in FIG. 1 is of generally channel shape having a web W surface at the closed side of the stud, and a pair of generally parallel opposing flange surfaces extending laterally outwardly and perpendicular from the web W
surface. One flange FF constitutes a front flange at the front of the stud and the other flange FR constitutes a rear flange at the rear of the stud. Inwardly turned lip L surfaces are located at the outer edges of the flanges. The width of the flanges frequently varies from one manufacturer to another. In addition, the width of the lips L may also vary. While a metal stud is shown in FIG. 1, it will be understood that clip 10 of the present invention is 1 S also adapted for use with a conventional wood stud SW of rectangular cross section, as illustrated in FIG. 2, which has a front face FF at the front of the stud and a rear face FR
(not shown) at the rear of the stud. Also, for purposes of disclosure, the below discussion of clip 10, when applicable, relates to both the metal stud SM and the wood stud SW.
Clip 10 comprises a first clip part and a second clip part generally indicated at 15 and 20, respectively. For economical manufacture, the first clip part 1 S
(FIG. 5) and the second clip part 20 (FIG. 9) may be stamped individually from a flat sheet metal blank, preferably heat-treated and spring-tempered steel, then bent and integrally formed in accordance with a main bending profile so as to accommodate different wall stud sizes. As shown in FIGS. I-3 and 13, the first clip part 1 S is engageable with the front flange FF
surface of the stud SM in a conventional manner for securing the clip 10 to the stud. The second clip part 20 holds the electrical box B to be mounted on the stud SM
and is engageable with the first clip part 1 S and may be engageable, in a preferred embodiment, with the stud Sr,,.
The first clip part 15 includes a middle portion 14, a first side portion 16 and a second side portion 17. The first side portion 16 extends generally upwardly, as viewed in FIGS. 7 and 13, from the left edge 18 of the middle portion 14. At least one barb or prong 19, preferably a first pair of barbs or prongs 19, extend downwardly from the first side portion 16 and terminate at pointed tips 21. The prongs 19 are bent so that they also project inwardly with respect to the middle portion 14. Similarly, the second side portion 17 extends generally upwardly, as viewed in FIGS. 7 and 13, from the right edge 22 of the middle portion 14. The second side portion 17 is bent outwardly, and at least one barb or prong 23, preferably a second pair of barbs or prongs 23, project downwardly and inwardly from the distal end of the second side portion 17 and terminate at pointed tips 24. A
relatively flat leg 25 extends upwardly from the top edge 30 of the second side portion 17.
The lateral separation of the pointed tips 21, 24 of the first and second pair of prongs 19, 23 is su~ciently predetermined, typically less that the lateral width of the stud SM, so that the pointed tips 21 of the first pair of prongs 19 are engageable with the forwardmost lip L surface and the pointed tips 24 of the second pair of prongs 23 are engageable with the web W surface so that the prongs 19, 23 grip the stud SM
to secure the 1 S first clip part 1 S onto the front flange FF surface of the stud SM for securing the clip I 0 to the stud SM. Clip 10 may be further secured to the stud SM by a fastener (not shown) such as a nail or screw received through a hole 26 in the middle portion 14 of the first clip part I 5 and piercing the front flange FF surface.
The second clip part 20 comprises a relatively flat leg 35 which, as best seen in FIG.
I 3, extends in a generally vertically oriented plane substantially parallel to the leg 25 of the first clip part 15. Extending generally downwardly from the bottom edge 27 of the leg 35 is a box clip arm, generally indicated at 28. The clip arm 28 includes a lateral portion 29 projecting generally laterally outwardly from the bottom edge 27 of leg 25, and a clip portion 31 extending downwardly from an outer edge 32 of the lateral portion 29 in a plane generally parallel to the plane of the leg 35. The lower end 33 of the clip portion 31, as best seen in FIGS. 10 and 13, curves back upon itself to form a horizontally extending, upwardly opening channel 34 having an inner wall 36 and an outer wall 37. An elongate opening 38 in the clip arm 28, as best seen in the flat configuration of the second clip part 20 (FIG. 9), facilitates forming of the clip portion 31 of the clip arm 28 and reduces the weight of the second clip part 20.
_7_ The channel 34 is adapted to receive a front edge 39 of the side wall 11 of the electrical box B (FIGS. 1, 2, 13). At least one barb or prong 41, preferably a third pair of barbs or prongs 4l having pointed tips, project inwardly and downwardly, as viewed in FIGS. 10 and 13, from the side edges of the outer wall 37 of the channel 34.
The S separation of these tips of the prongs 41 and the inner wall 36 of the channel 34 is preferably less than the thickness of the side wall 11 of the electrical box B
so that the tips of the prongs 41 resiliently engage the side wall 11 of the electrical box B
when it is received in the channel for securing the box B in a fixed position to the second clip part 20.
At least one support member 42 projects generally laterally inwardly, as viewed in FIGS. 10 and 13, preferably from the mid portion of the flat leg 35 of the second clip part 20, and preferably all the way to the web W surface of the stud SM. In a preferred embodiment, the second clip part 20 utilizes a pair of support members 42.
Each support member 42 includes an inwardly or outwardly turned lip portion 43 for engaging the web W surface during operation. When the clip 10 is attached to the stud SM and the electrical box B is clipped onto the second clip part 20, as shown in FIG. 13, the support members 42 extend between the flat leg 35 and the webbing W surface of the stud SM as a means to provide support for the box B when a force is applied inward of the box B, generally in the direction of arrow A (FIG. 13 ), against flexing of the clip 10. Moreover, when an inward force is applied generally in the direction of arrow A, the turned lip portions 43 of the support members 42 engage the webbing W surface of the stud as a means for supporting and substantially preventing any or further laterally inward movement of the box B.
As best illustrated in FIGS. 3, 4 and 13, when the two clip parts 15, 20 are assembled, the flat leg 3 5 of the second clip part 20 is in generally parallel, face-to-face relation with the flat leg 25 of the first clip part 15. The leg 35 of the second clip part 20 is slidable relative to the leg 25 of the first clip part 15 lengthwise of the leg of the first clip part for adjusting the position of the electrical box B held by the second clip part in front-to-rear direction relative to the stud. The electrical box B may thus be adjusted according to the thickness of the drywall D mounted on the stud, so that the front of the electrical box B is immediately adjacent the front of an opening (not shown) in the drywall.
It should be noted in this regard that it is important that the front of the electrical box B be slightly _g_ recessed into the drywall D a distance such that a cover plate (not shown) fastened to the box lies flush with the front of the drywall. The recessed position of the front of the electrical box B allows the mounting screws (not shown) of the cover plate to flex the cover plate slightly inwardly into the opening when the cover plate is mounted on the box S so that the cover plate is held securely against the drywall. Because the thickness of drywall varies, it is necessary to adjust the position of the electrical box in front-to-rear direction to ensure a proper fit of the cover plate on the drywall.
In a preferred embodiment, the pair of support members 42 projecting from the flat leg 3 S of the second clip part 20 also function as an alignment means for maintaining the leg 35 of the second clip part 20 in longitudinal alignment with the flat leg 25 of the first clip part 15 as the leg of the second clip part is slidably adjusted relative to the leg of the first clip part. As best seen in FIGS. 4 and 13, the support members 42 preferably extend generally inwardly (FIG. 13), with respect to the middle portion 14 of the first clip part 15, from the mid portion of leg 3 5 of the second clip part 20 and over opposite upper 44 and lower 46 edges of the leg 25 of the first clip part 15. The support members 42 define a guideway between them for receiving the leg 25 of the first clip part 1 S to guide the leg of the first clip part lengthwise of the leg 35 of the second clip part 20.
The leg 35 of the second clip part 20 is adjusted in a selected position of lengthwise adjustment relative to the leg 25 of the first clip part 1 S by an adjustment means. In a preferred embodiment, the adjustment means includes two generally parallel rows of apertures 47 through the leg 25 of the first clip part 15 at equally spaced intervals adjacent the opposing upper 44 and lower 46 edges of the leg 25 of the first clip part 15. Each opposing pair of apertures 47 corresponds to a position of lengthwise adjustment of the leg 35 of the second clip part 20 relative to the leg 25 of the first clip part 15. As best illustrated in FIG. 11, the adjustment means further includes a pair of relatively short adjustment members 48 integrally formed in the leg 35 of the second clip part 20 and projecting generally inwardly (FIG. 13) toward the leg 25 of the first clip part 1 S. The pair of adjustment members 48 are receivable through a selected corresponding pair of apertures 47 in the leg 25 of the first clip part 15 to substantially prevent longitudinal movement of the legs 25, 35 relative to one another.
The guideway defined by the support members 42 substantially prevents the legs 25, 35 from twisting in their respective planes relative to each other as they are adjusted so that the adjustment members 48 are always received in corresponding respective apertures 47 which are aligned for maintaining the electrical box B in substantially vertical S orientation. Also, the guideway assures proper alignment of the legs 25, 35 so that the plane including the front edge 39 of the electrical box B is maintained parallel with the drywall without exercise of special care on the part of a person adjusting the clip 10.
A fastener means, preferably a screw fastener 49, locks or secures the first and second clip parts 1 S, 20 in assembly. As best seen in FIGS. 3 and 4, the screw 49 is received through a slot 51 in the leg 35 of the second clip part 20, which extends lengthwise of the leg 3 S, and through an opening 52 in the leg 25 of the first clip part 15.
The opening 52 is formed with a thread for engaging the thread of the screw 49. As shown in FIG. 4, the screw 49, when tightened, locks the adjustment members 48 in the selected apertures 47 so that the legs 25, 35 may not slide relative to each other, thus fixing the I S selected relative lengthwise position of the legs. The screw 49 may be loosened so that the legs 25, 35 can be pulled apart a relatively short distance sufficient for withdrawal ofthe adjustment members 48 from their selected pair of apertures 47 so that the leg 35 of the second clip part 20 can be slidably adjusted relative to the first clip part I
5. Although the legs are pulled apart, the leg 25 of the first clip part 15 remains in the guideway between the support members 42 of the second clip part 20 so that the legs cannot be twisted out of lengthwise alignment during adjustment. The screw 49 may then be retightened to draw the legs 25, 35 together, as shown in FIGS. 4 and 13, for insertion of the adjustment members 48 into the newly selected apertures 47 to lock the legs in a newly selected position of adjustment.
The clip 10 is easily and accurately manipulated because the clip parts 15, 20 remain assembled during adjustment because of the fastener means so that the clip parts do not have to be held together by hand as they are being adjusted. In addition, however, the second clip part 20 includes a temporary holding means for holding the first and second clip parts 15, 20 together during initial assembly before screw 49 is installed so that the clip parts do not have to be held together by hand. In a preferred embodiment, the holding means comprises inwardly or outwardly turned tabs 53 at the distal ends of each adjustment member 48. Until screw 49 is operatively installed, the tabs 53 will engage an inside surface 54 of leg 25 of the first clip part 15 thereby holding the two clip parts 15, 20 together until screw 49 is installed, as best illustrated in FIG. 4.
It should also be understood that a permanent fastener may be applied to hold the legs 25, 35 of clip parts 15, 20 in a fixed, unalterable relative position such as when it is known that a large number of clips 10 are to be used with drywall of a single thickness.
Furthermore, while the clip 10 is shown attached to the closed side of the stud SM, it should be understood that the length of the support members 42 may be adjusted to accommodate attachment of the clip 10 to the open side of the stud SM.
Moreover, support members 42 may be utilized and fianction substantially the same when clip 10 is attached to a wood stud 5~,,.
Although a preferred embodiments) of the present invention has been described above by way of example, it will be understood by those skilled in the field that modifications may be made to the disclosed embodiments) which are within the scope of the invention as defined by the appended claims.
surface. One flange FF constitutes a front flange at the front of the stud and the other flange FR constitutes a rear flange at the rear of the stud. Inwardly turned lip L surfaces are located at the outer edges of the flanges. The width of the flanges frequently varies from one manufacturer to another. In addition, the width of the lips L may also vary. While a metal stud is shown in FIG. 1, it will be understood that clip 10 of the present invention is 1 S also adapted for use with a conventional wood stud SW of rectangular cross section, as illustrated in FIG. 2, which has a front face FF at the front of the stud and a rear face FR
(not shown) at the rear of the stud. Also, for purposes of disclosure, the below discussion of clip 10, when applicable, relates to both the metal stud SM and the wood stud SW.
Clip 10 comprises a first clip part and a second clip part generally indicated at 15 and 20, respectively. For economical manufacture, the first clip part 1 S
(FIG. 5) and the second clip part 20 (FIG. 9) may be stamped individually from a flat sheet metal blank, preferably heat-treated and spring-tempered steel, then bent and integrally formed in accordance with a main bending profile so as to accommodate different wall stud sizes. As shown in FIGS. I-3 and 13, the first clip part 1 S is engageable with the front flange FF
surface of the stud SM in a conventional manner for securing the clip 10 to the stud. The second clip part 20 holds the electrical box B to be mounted on the stud SM
and is engageable with the first clip part 1 S and may be engageable, in a preferred embodiment, with the stud Sr,,.
The first clip part 15 includes a middle portion 14, a first side portion 16 and a second side portion 17. The first side portion 16 extends generally upwardly, as viewed in FIGS. 7 and 13, from the left edge 18 of the middle portion 14. At least one barb or prong 19, preferably a first pair of barbs or prongs 19, extend downwardly from the first side portion 16 and terminate at pointed tips 21. The prongs 19 are bent so that they also project inwardly with respect to the middle portion 14. Similarly, the second side portion 17 extends generally upwardly, as viewed in FIGS. 7 and 13, from the right edge 22 of the middle portion 14. The second side portion 17 is bent outwardly, and at least one barb or prong 23, preferably a second pair of barbs or prongs 23, project downwardly and inwardly from the distal end of the second side portion 17 and terminate at pointed tips 24. A
relatively flat leg 25 extends upwardly from the top edge 30 of the second side portion 17.
The lateral separation of the pointed tips 21, 24 of the first and second pair of prongs 19, 23 is su~ciently predetermined, typically less that the lateral width of the stud SM, so that the pointed tips 21 of the first pair of prongs 19 are engageable with the forwardmost lip L surface and the pointed tips 24 of the second pair of prongs 23 are engageable with the web W surface so that the prongs 19, 23 grip the stud SM
to secure the 1 S first clip part 1 S onto the front flange FF surface of the stud SM for securing the clip I 0 to the stud SM. Clip 10 may be further secured to the stud SM by a fastener (not shown) such as a nail or screw received through a hole 26 in the middle portion 14 of the first clip part I 5 and piercing the front flange FF surface.
The second clip part 20 comprises a relatively flat leg 35 which, as best seen in FIG.
I 3, extends in a generally vertically oriented plane substantially parallel to the leg 25 of the first clip part 15. Extending generally downwardly from the bottom edge 27 of the leg 35 is a box clip arm, generally indicated at 28. The clip arm 28 includes a lateral portion 29 projecting generally laterally outwardly from the bottom edge 27 of leg 25, and a clip portion 31 extending downwardly from an outer edge 32 of the lateral portion 29 in a plane generally parallel to the plane of the leg 35. The lower end 33 of the clip portion 31, as best seen in FIGS. 10 and 13, curves back upon itself to form a horizontally extending, upwardly opening channel 34 having an inner wall 36 and an outer wall 37. An elongate opening 38 in the clip arm 28, as best seen in the flat configuration of the second clip part 20 (FIG. 9), facilitates forming of the clip portion 31 of the clip arm 28 and reduces the weight of the second clip part 20.
_7_ The channel 34 is adapted to receive a front edge 39 of the side wall 11 of the electrical box B (FIGS. 1, 2, 13). At least one barb or prong 41, preferably a third pair of barbs or prongs 4l having pointed tips, project inwardly and downwardly, as viewed in FIGS. 10 and 13, from the side edges of the outer wall 37 of the channel 34.
The S separation of these tips of the prongs 41 and the inner wall 36 of the channel 34 is preferably less than the thickness of the side wall 11 of the electrical box B
so that the tips of the prongs 41 resiliently engage the side wall 11 of the electrical box B
when it is received in the channel for securing the box B in a fixed position to the second clip part 20.
At least one support member 42 projects generally laterally inwardly, as viewed in FIGS. 10 and 13, preferably from the mid portion of the flat leg 35 of the second clip part 20, and preferably all the way to the web W surface of the stud SM. In a preferred embodiment, the second clip part 20 utilizes a pair of support members 42.
Each support member 42 includes an inwardly or outwardly turned lip portion 43 for engaging the web W surface during operation. When the clip 10 is attached to the stud SM and the electrical box B is clipped onto the second clip part 20, as shown in FIG. 13, the support members 42 extend between the flat leg 35 and the webbing W surface of the stud SM as a means to provide support for the box B when a force is applied inward of the box B, generally in the direction of arrow A (FIG. 13 ), against flexing of the clip 10. Moreover, when an inward force is applied generally in the direction of arrow A, the turned lip portions 43 of the support members 42 engage the webbing W surface of the stud as a means for supporting and substantially preventing any or further laterally inward movement of the box B.
As best illustrated in FIGS. 3, 4 and 13, when the two clip parts 15, 20 are assembled, the flat leg 3 5 of the second clip part 20 is in generally parallel, face-to-face relation with the flat leg 25 of the first clip part 15. The leg 35 of the second clip part 20 is slidable relative to the leg 25 of the first clip part 15 lengthwise of the leg of the first clip part for adjusting the position of the electrical box B held by the second clip part in front-to-rear direction relative to the stud. The electrical box B may thus be adjusted according to the thickness of the drywall D mounted on the stud, so that the front of the electrical box B is immediately adjacent the front of an opening (not shown) in the drywall.
It should be noted in this regard that it is important that the front of the electrical box B be slightly _g_ recessed into the drywall D a distance such that a cover plate (not shown) fastened to the box lies flush with the front of the drywall. The recessed position of the front of the electrical box B allows the mounting screws (not shown) of the cover plate to flex the cover plate slightly inwardly into the opening when the cover plate is mounted on the box S so that the cover plate is held securely against the drywall. Because the thickness of drywall varies, it is necessary to adjust the position of the electrical box in front-to-rear direction to ensure a proper fit of the cover plate on the drywall.
In a preferred embodiment, the pair of support members 42 projecting from the flat leg 3 S of the second clip part 20 also function as an alignment means for maintaining the leg 35 of the second clip part 20 in longitudinal alignment with the flat leg 25 of the first clip part 15 as the leg of the second clip part is slidably adjusted relative to the leg of the first clip part. As best seen in FIGS. 4 and 13, the support members 42 preferably extend generally inwardly (FIG. 13), with respect to the middle portion 14 of the first clip part 15, from the mid portion of leg 3 5 of the second clip part 20 and over opposite upper 44 and lower 46 edges of the leg 25 of the first clip part 15. The support members 42 define a guideway between them for receiving the leg 25 of the first clip part 1 S to guide the leg of the first clip part lengthwise of the leg 35 of the second clip part 20.
The leg 35 of the second clip part 20 is adjusted in a selected position of lengthwise adjustment relative to the leg 25 of the first clip part 1 S by an adjustment means. In a preferred embodiment, the adjustment means includes two generally parallel rows of apertures 47 through the leg 25 of the first clip part 15 at equally spaced intervals adjacent the opposing upper 44 and lower 46 edges of the leg 25 of the first clip part 15. Each opposing pair of apertures 47 corresponds to a position of lengthwise adjustment of the leg 35 of the second clip part 20 relative to the leg 25 of the first clip part 15. As best illustrated in FIG. 11, the adjustment means further includes a pair of relatively short adjustment members 48 integrally formed in the leg 35 of the second clip part 20 and projecting generally inwardly (FIG. 13) toward the leg 25 of the first clip part 1 S. The pair of adjustment members 48 are receivable through a selected corresponding pair of apertures 47 in the leg 25 of the first clip part 15 to substantially prevent longitudinal movement of the legs 25, 35 relative to one another.
The guideway defined by the support members 42 substantially prevents the legs 25, 35 from twisting in their respective planes relative to each other as they are adjusted so that the adjustment members 48 are always received in corresponding respective apertures 47 which are aligned for maintaining the electrical box B in substantially vertical S orientation. Also, the guideway assures proper alignment of the legs 25, 35 so that the plane including the front edge 39 of the electrical box B is maintained parallel with the drywall without exercise of special care on the part of a person adjusting the clip 10.
A fastener means, preferably a screw fastener 49, locks or secures the first and second clip parts 1 S, 20 in assembly. As best seen in FIGS. 3 and 4, the screw 49 is received through a slot 51 in the leg 35 of the second clip part 20, which extends lengthwise of the leg 3 S, and through an opening 52 in the leg 25 of the first clip part 15.
The opening 52 is formed with a thread for engaging the thread of the screw 49. As shown in FIG. 4, the screw 49, when tightened, locks the adjustment members 48 in the selected apertures 47 so that the legs 25, 35 may not slide relative to each other, thus fixing the I S selected relative lengthwise position of the legs. The screw 49 may be loosened so that the legs 25, 35 can be pulled apart a relatively short distance sufficient for withdrawal ofthe adjustment members 48 from their selected pair of apertures 47 so that the leg 35 of the second clip part 20 can be slidably adjusted relative to the first clip part I
5. Although the legs are pulled apart, the leg 25 of the first clip part 15 remains in the guideway between the support members 42 of the second clip part 20 so that the legs cannot be twisted out of lengthwise alignment during adjustment. The screw 49 may then be retightened to draw the legs 25, 35 together, as shown in FIGS. 4 and 13, for insertion of the adjustment members 48 into the newly selected apertures 47 to lock the legs in a newly selected position of adjustment.
The clip 10 is easily and accurately manipulated because the clip parts 15, 20 remain assembled during adjustment because of the fastener means so that the clip parts do not have to be held together by hand as they are being adjusted. In addition, however, the second clip part 20 includes a temporary holding means for holding the first and second clip parts 15, 20 together during initial assembly before screw 49 is installed so that the clip parts do not have to be held together by hand. In a preferred embodiment, the holding means comprises inwardly or outwardly turned tabs 53 at the distal ends of each adjustment member 48. Until screw 49 is operatively installed, the tabs 53 will engage an inside surface 54 of leg 25 of the first clip part 15 thereby holding the two clip parts 15, 20 together until screw 49 is installed, as best illustrated in FIG. 4.
It should also be understood that a permanent fastener may be applied to hold the legs 25, 35 of clip parts 15, 20 in a fixed, unalterable relative position such as when it is known that a large number of clips 10 are to be used with drywall of a single thickness.
Furthermore, while the clip 10 is shown attached to the closed side of the stud SM, it should be understood that the length of the support members 42 may be adjusted to accommodate attachment of the clip 10 to the open side of the stud SM.
Moreover, support members 42 may be utilized and fianction substantially the same when clip 10 is attached to a wood stud 5~,,.
Although a preferred embodiments) of the present invention has been described above by way of example, it will be understood by those skilled in the field that modifications may be made to the disclosed embodiments) which are within the scope of the invention as defined by the appended claims.
