1. Field of the Invention
The present invention relates to recessed articles such as lighting fixtures.
2. Description of the Related Art
Recessed light fixtures, often called “pot lights”, are in widespread use in residential and commercial premises. They appeal to designers both for the fact that they take up virtually no space in a room, being recessed into the ceiling, and for their aesthetic versatility and appeal.
A typical recessed light fixture comprises a housing, which is usually cylindrical, a socket for receiving a floodlight, halogen bulb or other lamp, and a housing trim for aesthetic purposes which is affixed over the mouth of the housing after the housing has been mounted into the ceiling and covers the housing flange.
An example of a recessed lighting fixture is disclosed in U.S. Pat. No. 5,609,414, issued Mar. 11, 1997, entitled RECESSED LIGHTING FIXTURE, in which a pair of outwardly biased retaining clips is mounted in a housing. The entire subject matter of U.S. Pat. No. 5,609,414, issued Mar. 11, 1997, entitled RECESSED LIGHTING FIXTURE, is incorporated by reference.

Several preferred embodiments of the present invention will now be described, by way of example only, with reference to the appended drawings in which:
a is a fragmentary side view of a portion of the housing assembly of
a is a perspective view of an alternative retaining clip to that shown in
a is a side view of a portion of the housing assembly of
b is a side view of a portion of an alternative housing assembly, according to
FIGS. 5 to 8 fragmentary perspective views according to
FIGS. 14 to 17 show variations of other retaining clips;
a is a sectional view taken on line 22a-22a of
FIGS. 1 to 8 show various portions of a recessed article, in this case a recessed lighting fixture 10. The fixture has a housing 12 with a back wall 14 and a cylindrical side wall 16 extending from the back wall 14. A lip 18 extends outwardly from the side wall 16. In this case, the housing 12 is formed of one piece construction, such as by way of a deep drawing manufacturing step.
Located in the side wall is at least one, in this case two elongate slot formations 20 extending along an axis 20a substantially perpendicular to the back wall 14. Each slot formation 20 has a pair of oppositely extending lateral edge formations, in the form of slot extensions 22, each slot extension having a first dimension 22a.
A retaining clip 32 is located in each slot formation 20 for movement therealong. Referring to
The body portion 38 includes a pair of peripheral regions in the form of arm portions 40 which are adjacent the neck portion 36 and which extend outwardly therefrom. Each arm portion 40 has a second dimension 40a exceeding the first dimension 22a of the corresponding slot extension 22. This permits each arm portion 40 to travel along an outer surface 16b of a corresponding side wall 16 and over the corresponding lateral slot extension 22.
The body portion 38 includes a bend section 42 with a bend 42a. In this case, the arm portions 40 are centrally located in the bend section 42. However, other arrangements may be provided in which the arm portions 40 are located either above or below the bend, as desired, with or without a bend section, as desired.
The body portion 38 is arranged to be biased outwardly from the housing 12. The body portion 38 is joined to a third portion in the form of an anchor portion 44, which is arranged to extend through the slot formation 20 and be held in a retained position. As can be seen in
The anchor portion 44 is also provided with a pair of abutment portions shown at 47 to engage an upper surface 56a of a ceiling panel as shown at 56 in
A displacement portion 50, including a threaded drive member, in this case screw fastener shown at 52, is provided to displace the clip 32 along the slot formation 20. The head portion 34 includes a first threaded passage 34a, for threaded engagement with screw fastener 52. A mounting flange 48 extends inwardly from a side wall 16 adjacent a corresponding slot formation 20 and includes a second passage 48a, which, in this case, is a clearance hole, to guide, but not threadably engage, screw fastener 52. The mounting flange 48 may be provided at other locations near the slot 22 or on the housing as desired.
The screw fastener 52 thus extends through the first and second passages 34a, and 48a. The anchor portion 44 includes a passage 44a to receive the screw fastener 52. In this case, the passage 44a is of sufficient dimension to enable the retaining clip to move relative to the screw fastener 52 between the locked and unlocked orientations, as can be seen by comparing
The body and anchor portions 38, 44 are joined at an offset connecting portion 39. Located in the offset connecting portion 39 is a retaining section 39a providing a pair of retaining regions 39b, each to engage a corresponding lateral edge formation, as can be seen in
As can be seen in
However, if desired, the slot extension 20 may form other shaped openings, such as a substantially triangularly shaped opening, as is shown in
Referring to
An alternative clip is shown at 32 in
It will thus be seen that the screw fastener 52 may be used to locate and/or displace the retaining clip 32 relative to one or more of:
The passage 44a in the anchor portion 44 receives the screw fastener 52. In this way, the fastener 52 is able in this instance to act as an anchor or restraining portion to restrain or limit the lateral travel of the clip outwardly from the housing in the fifth position. This occurs because the innermost region of the clip closes the passage 44a and the screw abuts this outermost region as the clip is drawn relatively tightly toward the lip 18. While the screw fastener in this case serves as a restraining portion, the anchor portion 44 may be provided with other formations, such as laterally extending flanges extending outwardly from the innermost region of the clip to engage the inner surface of the side wall rather than the screw. Moreover, the anchor portion may be provided with a structure similar to the head portion 34 at its lower end to provide means of limit outward travel of the clip relative to the housing. If desired, each of the lateral edge formations may be provided by other arrangements, such as by a pair of opposed tabs extending into the slot formation 20 from a slot periphery, rather than by the opposed slot extensions 22 shown above.
The recessed lighting fixture 10 may be installed in the following manner. First a passage 56b is formed in the ceiling panel 56 as shown in
The retaining clips 32 are held in the above mentioned first phase and the housing 10 is pushed through the passage 56b to the position as shown in
FIGS. 9 to 18 show various portions of another recessed lighting fixture 110. The fixture has a housing 112 with a back wall 114 and a cylindrical side wall 116 extending from the back wall 114. A lip 118 extends outwardly from the side wall 116.
Located in the side wall is at least one, in this case two elongate slot formations 120 extending along an axis 120a substantially perpendicular to the back wall 114. Each slot formation 120 has a pair of oppositely extending lateral slot extensions 122, each slot extension having a first dimension 122a.
A retaining clip 132 is located in each slot formation 120 for movement therealong. Referring to
The body portion 138 is arranged to be biased outwardly from the housing 112. The body portion 138 is joined to an anchor portion 144, which is arranged to extend through the slot formation 120. The anchor portion 144 includes a pair of opposed locking flanges 146, each of which travels along the inner surface 116a of the corresponding side wall 116 on opposite sides of the slot formation 120. The locking flanges 146 are dimensioned to pass through a corresponding slot extension 122 to transfer the retaining clip 132 between a locked orientation (as shown in
A displacement portion shown at 150 is provided to displace the clip 132 along the slot formation 120. The head portion 134 includes a first passage 134a. A mounting flange 148 extends inwardly from a side wall 116 adjacent a corresponding slot formation 120 and includes a second passage 148a.
The displacement portion 150 includes a threaded drive member, in the form of a screw fastener 152, extending through the first and second passages 134a, and 148a. The anchor portion 144 includes a passage 144a to receive the screw fastener 152. In this case, the passage 144a is of sufficient dimension to enable the retaining clip to move relative to the screw fastener 152 between the locked and unlocked orientations.
In this case, the body and anchor portions 138, 144 are joined at an offset connecting portion 139. This allows the body portion 138 to lie along the side wall 116 in the locked position, as can be seen in
It will thus be seen that a screw fastener 152 may be used to locate and/or displace the retaining clip 132 relative to one or more of:
The remaining phases are similar to those for the housing 10.
The recessed lighting fixture 110 may be installed in the passage 56b formed in the ceiling wall panel 56 in a manner similar to that discussed earlier.
Thus, as shown in
Another recessed lighting fixture is shown at 200 in FIGS. 19 to 22. The recessed lighting fixture 200 is arranged to receive a light source therein and has a power supply portion 202 for supplying power to the light source, by way of a wiring harness 204. The wiring harness 204 includes a plurality of power cables 204a joined to a socket portion 204b. In this example, the power supply portion 202 includes a support portion 206 which is mounted adjacent the back wall 208 of the housing 210 for contact therewith. The support portion 206 and back wall 208 have aligned first and second cable passages 206a, 208a (
The support portion 206 is movable between a first rest position against the back wall 208 and an extended second position in which a segment of the support portion is displaced from the back wall 208 to permit the power supply portion 202 to be moved relative to the housing 210 during installation at a designated recessed lighting site.
The back wall 208 and the support portion 206 thus form an inner region 212 therebetween (
The support portion 206 includes a support plate 216 with the first cable passage 206a formed in a central region thereof. The support plate 216 has a peripheral edge 216a and the first cable passage 206a is open thereto by way of slot 216b. The slot 216b thus provides a convenient way to deliver the wiring harness 204 to the first cable passage 206a without having to disassemble the socket portion 204b or requiring the latter to be installed after the power cable 204a is located in the first cable passage 206a. That being said, the wiring harness 204 may indeed be installed by disassembling the socket portion 204b if desired, or by installing the power cable 204a first in the first cable passage 206a before installing the socket portion thereon. The slot 216b may also be configured differently than that shown in the figures. It may instead form a larger access opening directed longitudinally or laterally relative to the first support plate, among other arrangements.
The support plate 216 includes a first pair of fastener passages 216c at a first location and a second pair of fastener passages 216d at a second location. The first and second fastener passages 216c, 216d are arranged to receive fasteners therethrough. The second fastener passages 216d are in threaded form while the first fastener passages 216c are clearance holes which are aligned with corresponding threaded passages 208d.
Referring to
As can be seen in
In this case, the guide member 214 has a neck portion 214b with a v shaped cross section, as shown in
The flange 214a can be seen to extend partway along the boundary of the first cable passage, for example about 180 degrees along the boundary. However, the flange may, if desired, extend more or less than 180 degrees if desired. For instance, the flange may extend the entire periphery of the passage. In this latter case, then, the flange may be provided in the form of a cylindrical skirt depending from the first cable passage, as shown in dashed lines at 215. In addition, the flange may also, in some cases, be arranged to extend outwardly from the support plate 216 in the vicinity of the first cable passage or in other locations relative thereto. For instance, the flange may extend outwardly from the support plate at a location beyond the periphery of the side wall of the housing, for example as shown by the dashed lines at 218.
There are other ways in which the support plate 216 may be mounted on the back wall. For instance, the support plate may be welded, riveted or bonded to the back wall. A portion of the support plate may be integrally formed with the back wall if desired. The support plate 216 is biased toward the back wall 208 by the natural spring rate of the support plate when fastened to the back wall. The support plate 216 may be provided with other forms of biasing, such as by a pivot connection between the support plate 216 and the back wall, or between two sections of the support plate itself.
Thus, the light fixture 200 is used in the following manner. First, the light fixture may be assembled as described above. Then, with the appropriate passage 56b formed in the ceiling panel 56, the light fixture 200 is installed by first directing the power supply portion 202 through the passage 56a. To do this, the power supply portion is oriented relative to the housing 210, so that the power supply portion transferred from its lateral position relative to the housing as shown in solid lines in
The power supply portion 202 may be provided in different configurations and be coupled with the mounting plate 220a and thus to the plate 216 using other configurations. For instance, the mounting plate 220a and the support plate 216 may be integrally formed, if desired. The support plate may be coupled to the housing 210 at locations other than the back wall 208.
As can be seen, the side wall of the housing shown above are arranged to form a cylinder, but maybe provided in other configurations, such as multiple sided cross sectioned structures, such as squares, rectangles, triangles and the like. The housing may also be formed of more than one part, as desired. While the lip 18 is shown above integrally formed with the housing 12, but may be separate therefrom and attachable thereto, if desired.
The drive member may be provided in other configurations, such as by way of a spring-loaded pin, for example.
The retaining clips above described include a first movement away from the ceiling or wall panel to release the clip and a second opposite movement toward the panel to tighten the clip against the ceiling or wall panel. However, the clip may be arranged to provide the release function and the tightening function in the same direction if desired.
While the recessed lighting fixture 10 is described with respect to its installation in a ceiling panel, the fixture, if desired, may also be mounted in other panels that are not necessarily ceiling panels in some cases. For instance, the fixture may be installed a wall panel or a floor panel. Moreover, the housing described herein may be used to mount articles other than light fixtures onto panels, including ceiling, wall and floor panels, or other panels, for that matter.
The retaining clip, in some cases, may also be retained as described by using only one slot extension or lateral slot formation and one corresponding arm or body portion, and/or one retaining region, rather than the opposed pair configurations as described above.
The head, neck and body portions 34, 36 and 38 provide one configuration of the first, second and third portions. Other configurations may also be used if desired without having the features associated with the head, neck and body portions as described above. In addition, the spring-loaded, while the body portion is shown above slightly bowed in light of this spring-loaded orientation. There may be other examples in which the body portion may be spring loaded without being bowed in the manner illustrated above. Furthermore, other means may be provided for biasing the body portion outwardly from the housing, in addition to or as an alternative to, the inherent resiliency to the body portion.
While the present invention has been described for what are presently considered the preferred embodiments, the invention is not so limited. To the contrary, the invention is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. The scope of the following claims is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures and functions.
