DESCRIPTION
[0017] The apparatus 1 shown in FIG. 1 has parts which, as
described below, are examples of the elements recited in the
claims.
[0018] The apparatus includes an electrical bracket 10. The bracket
10 is used for mounting a low-voltage electrical device, such as a
cable jack 12, to a wall stud 14 with front and side surfaces 16
and 18. The bracket 10 includes a rectangular frame 20 for
enclosing the electrical device 12. The frame 20 is centered on
perpendicular longitudinal 21 and lateral axes 23. The frame 20 has
longitudinally-extending first and second opposite side walls 32
and 34. The frame 20 further has transversely-extending first and
second opposite end walls 36 and 38. The walls 32, 34, 36 and 38
define a cavity 41 and surround a front opening 43 through which
the electrical device 12 can be inserted into the cavity 41.
[0019] The frame 20 can be mounted to the stud 14 in three
positions. In a first side-mounted position of the frame 20, the
first side wall 32 faces and abuts the side surface 18 of the stud
14. In a second side-mounted position of the frame 20, the second
side wall 34 faces and abuts the side surface 18 of the stud 14. In
an end-mounted position of the frame 20, the first end wall 36
faces, but is spaced from, the side surface 18 of the stud 14.
Adjoining the frame 20 are various structures for securing the
device 12 to the frame 20, attaching the frame 20 to a stud 14 and
stabilizing the frame 20 relative to the stud 14. These structures
are described as follows.
[0020] Two mounting bosses 60 extend inward from respective end
walls 36 and 38, adjacent to the front opening 43. Each boss 60 has
a bore 61 for securing the electrical device 12 to the frame 20.
This is done by inserting two self-threading screws 62 through a
yoke 64 of the device 12 and screwing the screws 62 into the bores
61.
[0021] Each wall 32, 34, 36 and 38 shown in FIG. 1 has a front end
72, 74, 76 and 78 located at the front opening 43 of the frame 20.
The front ends 72, 74, 76 and 78 are defined by edges of the walls
32,34,36 and 38. Each of the walls 32,34,36 and 38 further has
arear end 82,84,86 and 88 located at a rear opening 89 of the frame
20.
[0022] As shown in FIGS. 2 and 3, a length L of the frame 20 is
defined by the end walls 36 and 38. A width W of the frame 20 is
defined by the side walls 32 and 34. A depth D of the frame 20 is
defined by and between the front and rear ends 72 and 82 of the
side walls 32 and 34. The rear ends 82 and 84 of the side walls 32
and 34 are defined by edges of the side walls 32 and 34. However,
the rear ends 86 and 88 of the end walls 36 and 38, denoted by a
dashed lines in FIGS. 1 and 4, do not correspond to a visible
structural feature. That is due to first and second extension
plates 90 and 91 extending seamlessly from the rear ends 86 and 88
of first and second end walls 36 and 38. The extension plates 90
and 91 extend rearward from, and parallel to, the respective end
walls 36 and 38 to a location rearward from the side walls 32 and
34.
[0023] Each extension plate 90 and 91 has a pass-through hole 92.
The hole 92 is for passing electrical wires from outside the frame
20 to the device 12 in the frame 20. A semicircular first
perforation 93 in the plate 90 encircles the hole 91 to define a
first knock-out 94 that is larger than, and concentric with, the
hole 91. A semicircular second perforation 95 in the plate 90
encircles the first knock-out 94 to define a second knock-out 96
that is larger than, and concentric with, the first knockout
94.
[0024] A first side tab 102 is best shown in FIGS. 1 and 4. It
extends orthogonally from the first side wall 32 in a direction
transversely away from the second side wall 34. The first side tab
102 is configured to overlie the front surface 16 of the stud 14
when the frame 20 is being mounted in the first side-mounted
position. A rear surface 103 of the first side tab 102 is spaced
rearwardly from the front end 76 of the first side wall 32 by a
distance T equal to the thickness of drywall (not shown) that will
overlie the stud 14. This is so that, when the tab 102 overlies the
front stud surface 16, the front edges 72, 74, 76 and 78 of the
frame 20 will be flush with the front surface of the drywall. The
first side tab 102 has a perforation 104 along its line of
adjoinment 105 with the frame 20. This enables the tab 102 to be
removed from the frame 20 for applications where the tab 102 is not
needed.
[0025] A second side tab 112 extends orthogonally from the second
side wall 34 in a direction transversely away from the first side
wall 32. The second side tab 112 is configured to overlie the front
surface 16 of the stud 14 when the frame 20 is mounted in the
second side-mounted position. A rear surface 113 of the side tab
112 is spaced rearwardly from the front opening 43 by the distance
T equal to the thickness of the drywall. This is so that, when the
tab 112 overlies the front stud 14 surface, the front edges 72, 74,
76 and 78 of the frame 20 will be flush with the front surface of
the drywall.
[0026] Like the first side tab 102, the second side tab 112 has a
perforation 114 along its line of adjoinment 115 with the frame 20,
as shown in FIG. 3. This enables the second side tab 112 to be
removed from the frame 20 if the second side tab 112 is not needed.
The tab 112 has two nail holes 118 for fastening the tab 112 to the
front surface 16 of the stud 14 with nails. The tab 112 further has
a staple hole 119 for fastening the frame 10 to the stud 14 with a
staple (not shown). The staple can be hammered into the stud 14,
with one leg of the staple passing through the stapling hole 119,
and the other leg of the staple passing through one of the nail
holes 118.
[0027] An end tab 122 is best shown in FIGS. 1 and 4. It extends
orthogonally from the first end wall 36 in a direction
longitudinally away from the second end wall 38. The end tab 122 is
configured to overlie the front surface 16 of the stud 14 when the
frame 20 is mounted in the end-mounted position. As with the other
tabs 102 and 112, a rear surface 123 of the end tab 122 is spaced
rearwardly from the front opening 43 by the thickness T of the
drywall. The end tab 122 has nail holes 128 for fastening the end
tab 122 to the front stud surface 16 with nails.
[0028] A pair of first nail supports 142 and 144 are best shown in
FIGS. 1 and 3. The first supports 142 and 144 extend from the first
end wall 36 in a direction away from the second end wall 36. The
supports 142 and 144 adjoin the first end wall 36 at transversely
opposite sides of the first end wall 36. Each support 142 and 144
has a groove surface 146 and 148 configured to support and retain a
first nail 149 in an orientation in which the nail 149 extends
alongside the first end wall 36 and into the side surface 18 of the
stud 14 when the frame 20 is in the first side-mounted position.
Each support 142 and 144 further has a distal end defined by a stud
abutting edge 152 and 154 that is parallel to the first end surface
36 and spaced a stand-off distance S from the first end wall 36.
The stud abutting edge 152 and 154 is configured to abut the side
surface 18 of the stud 14 along a transversely-extending line of
abutment that is spaced from the first end wall 36 in a direction
toward the stud 14 when the frame 20 is in the end-mounted
position. The nail supports 142 and 144 thus space the frame 20
longitudinally away from the side surface 18 of the stud 14.
[0029] A pair of second nail supports 162 and 164 extend from the
second end wall 38 in a direction away from the first end wall 36.
The second nail supports 162 and 164 adjoin the second end wall 38
at transversely opposite sides of the second end wall 38. Each
support 162 and 164 has a groove surface 166 and 168 configured to
support a second nail 169 in an orientation in which the nail 169
extends alongside the second end wall 38 and into the side surface
18 of the stud 14 when the frame 20 is in the first side-mounted
position.
[0030] Two nail retainers 172 and 174 are best shown in FIGS. 2 and
3. The retainers 172 and 174 extend longitudinally from the second
end wall 38 in a direction away from the first wall 36. The two
nail retainers 172 and 174 are transversely spaced from each other
and are respectively adjacent the two second nail supports 162 and
164. The nail retainers 172 and 174 are configured to urge the
second nail 169 (FIG. 1) against the groove surfaces 166 and 168 of
the second nail supports 162 and 164, to retain the second nail 169
in the groove surfaces 166 and 168. The second nail 169 is thus
captured between the nail retainers 172 and 174 and the groove
surfaces 166 and 168.
[0031] Two front spacers 182 and 184 are best shown in FIGS. 2 and
4. They extend from the first end wall 36 in a direction
longitudinally away from the second end wall 38. The front spacers
182 and 184 adjoin the first end wall 36 adjacent transversely
opposite sides of the end tab 112. Each front spacer 182 and 184 is
in the form of a plate that is approximately parallel to the side
walls 32 and 34 and orthogonal to the end walls 36 and 38.
[0032] Each front spacer 182 and 184 has a stud abutting edge 192
and 194. The stud abutting edges 192 and 194 extend rearward from
transversely opposite edges 196 of the end tab 112. The stud
abutting edges 192 and 194 are spaced from the first end wall 36 by
the stand-off distance S. Each stud abutting edge 192 and 194 is
configured to abut the side surface 18 of the stud 14 along a line
of abutment when the frame 20 is in the end-mounted position. The
front spacers 182 and 184 stabilize and space the frame 20
longitudinally away from the side surface 18 of the stud 14.
[0033] Each front spacer 182 and 184 further has a
longitudinally-extendin- g nail abutting edge 202 and 204. The nail
abutting edges 202 and 204 are configured to urge the first nail
149 (FIG. 1) against the groove surfaces 146 and 148 of the first
nail supports 142 and 144, to retain the first nail 149 in the
groove surfaces 146 and 148. The first nail 149 is thus captured
between the groove surfaces 146 and 148 and the nail abutting edges
202 and 204.
[0034] Two rear spacers 212 and 214 are best shown in FIGS. 2 and
4. They extend from transversely opposite edges of the first
extension plate 90 in a direction longitudinally away from the
second extension plate 91. Each rear spacer 212 and 214 is a plate
that is approximately parallel to the side walls 32 and 34 and
perpendicular to the end walls 36 and 38.
[0035] Each rear spacer 212 and 214 has a stud-abutting edge 222
and 224 that is parallel to the end surface 36. These stud-abutting
edges 222 and 224 are spaced the stand-off distance S from the
extension plate 90, so as to be coplanar with the other
stud-abutting edges 152, 154, 192 and 194. Each stud-abutting edge
222, 224, 152, 154, 192 and 194 is configured to engage the side
surface 18 of the stud 14 along a longitudinally extending line of
contact when the frame 20 is in the end-mounted position. The rear
spacers 212 and 214, like the front spacers 182 and 184, stabilize
and space the frame 20 longitudinally away from the side surface 18
of the stud 14.
[0036] The frame 20 can be mounted to the stud 14 in the first
side-mounted position as follows. First, the second side tab 112
can, optionally, be torn away from the frame 20 along its
perforation 114, because the second side tab 112 is not needed for
mounting the frame 20 in the first side-mounted position. Next, as
shown in FIGS. 5 and 6, the first side surface 32 of the frame 20
is held flat against the side surface 18 of the stud 14, with the
first side tab 102 abuttingly overlying the front surface 16 of the
stud 14.
[0037] The first nail 149 is inserted between the nail abutting
surfaces 202 and 204 of the front spacers 182 and 184 and the
groove surfaces 146 and 148 (FIG. 3) of the first nail supports 142
and 144. As indicated by an arrow 231, the first nail 149 is
hammered into the side surface 18 of stud 14. The second nail 169
is similarly inserted between the nail retainers 172 and 174 (FIG.
3) and the groove surfaces 166 and 168 of the second nail supports
162 and 164. As indicated by an arrow 232, the second nail 169 is
hammered into the side surface 18 of stud 14. With the frame 20
thus fastened securely to the stud 14, the first side tab 102 can,
optionally, be broken away from the frame 20 along its perforation
104. This avoids the possibility of a bulge in the drywall that
later covers the tab 102.
[0038] The frame 20 can be mounted to the stud 14 in the second
side-mounted position as follows. First, the first side tab 102
(FIG. 1) can, optionally, be torn away from the frame 20 along its
perforation 104, because the first side tab 102 is not needed for
mounting the frame 20 in the second side-mounted position. Next, as
shown in FIGS. 7 and 8, the second side surface 34 of the frame 20
is held flat against the side surface 18 of the stud 14, with the
second side tab 112 abutting overlying the front surface 16 of the
stud-14. The second side tab 112 is fastened to the stud 14 by
hammering nails 240 through the nail holes 118 of the second side
tab 112 and into the stud 14, as indicated by arrows 241.
[0039] The frame 20 can be mounted to the stud 14 in the
end-mounted position as follows. First, the side tabs 102 and 112
shown in FIG. 1 can be torn away from the frame 20 along their
perforations 104 and 114, because the side tabs 102 and 112 are not
needed for mounting the frame 20 in the end-mounted position. Next,
as shown in FIGS. 9 and 10, the frame 20 is positioned such that
the stud abutting edges 152, 154, 192, 194, 222 and 224 abut the
side surface 18 of the stud 14, and the end tab 122 abuttingly
overlies the front surface 16 of the stud 14. Next, the end tab 122
is fastened to the stud 14 by hammering nails 250 through the holes
128 of the end tab 122 and into the front surface 16 of the stud
14.
[0040] As shown in FIG. 1, the bracket 10 further has two fastener
loops 260 extending rearward from the rear edge 82 of the first
