## Abstract

A mounting assembly for securing a fixture in a desired orientation. The assembly includes a fulcrum and an opposing structure each secured with respect to the fixture and positioned to receive a support member therebetween. The fulcrum defines a fulcrum plane and is positioned to pivotably engage one side of the support member. The assembly also includes at least one adjustable engager separately secured to the opposing structure for engaging the support member at position spaced from the fulcrum plane such that, when the support member is received between the fulcrum and the engager, adjustment of the engager holds the fixture in the desired orientation. In some embodiments, the fixture is a luminaire.

## Claims

### Claim 1

A mounting assembly for securing a fixture in a desired orientation, the assembly comprising:
a fulcrum and an opposing structure each secured with respect to the fixture and positioned to receive a support member therebetween, the fulcrum defining a fulcrum plane and being positioned to pivotably engage one side of the support member; and
at least one adjustable engager separately secured to the opposing structure for engaging the support member at position spaced from the fulcrum plane,
whereby, when the support member is received between the fulcrum and the engager, adjustment of the engager holds the fixture in the desired orientation.

### Claim 2 (depends on 1)

The mounting assembly of claim 1 wherein the fixture is a luminaire.

### Claim 3 (depends on 1)

The mounting assembly of claim 1 wherein the fulcrum is shaped to limit lateral movement of the support member thereagainst.

### Claim 4 (depends on 1)

The mounting assembly of claim 1 wherein the opposing structure is a portion of a mount housing secured with respect to the fixture for receiving the support member therein.

### Claim 5 (depends on 4)

The mounting assembly of claim 4 wherein the mount housing includes a fixture-adjacent end wall and a surrounding wall which extends from the end wall and includes the opposing structure.

### Claim 6 (depends on 5)

The mounting assembly of claim 5 wherein the fulcrum is part of a fulcrum member having a mounting portion secured to the end wall and an extension portion extending from the mounting portion along the surrounding wall to the fulcrum which protrudes from the extension portion.

### Claim 7 (depends on 6)

The mounting assembly of claim 6 wherein the fulcrum is shaped to limit lateral movement of the support member thereagainst.

### Claim 8 (depends on 7)

The mounting assembly of claim 7 wherein the fulcrum includes a row of teeth configured to engage the support member.

### Claim 9 (depends on 7)

The mounting assembly of claim 7 wherein the adjustable engager includes a yoke shaped to substantially conform to the shape of the support member.

### Claim 10 (depends on 4)

The mounting assembly of claim 4 wherein the mount housing has a longitudinal axis and includes an angle-referencing region shaped to engage the fixture-adjacent end of the support member to facilitate positioning of the mount housing within one of plural predetermined angle ranges with respect to the support member.

### Claim 11 (depends on 10)

The mounting assembly of claim 10 wherein:
the mount housing includes a fixture-adjacent end wall and a surrounding wall which extends from the end wall and includes the opposing structure; and
the angle-referencing region has a step-like configuration adjoining the end wall with steps each corresponding to one of the plural predetermined angle ranges.

### Claim 12 (depends on 11)

The mounting assembly of claim 11 wherein the predetermined angle ranges include ranges of about −5° to about 0°, about 0° to less than +5° and about +5° such that, depending on which of the steps is selected for engagement by the fixture-adjacent end of the support member, adjustment of the adjustable engager locks the mount housing at a particular angle with respect to the support member within the range of the selected step.

### Claim 13 (depends on 1)

The mounting assembly of claim 1 comprising a pair of the adjustable engagers each separately secured to the opposing structure, one on either side of the fulcrum plane.

### Claim 14 (depends on 13)

The mounting assembly of claim 13 wherein the adjustable engagers are spaced brackets adjustably secured with respect to the opposing structure, each of the spaced brackets having a yoke for engagement with the support member, the yoke being positioned at a selected distance with respect to the opposing structure.

### Claim 15 (depends on 14)

The mounting assembly of claim 14 further including, for each yoke, at least one adjustment pin in threaded engagement with the opposing structure for pushing the corresponding yoke against the support member.

### Claim 16 (depends on 15)

The mounting assembly of claim 15 including a pair of adjustment pins for each yoke, one at each end of the yoke.

### Claim 17 (depends on 15)

The mounting assembly of claim 15 wherein:
each yoke has a pin-receiving aperture through which a corresponding pin extends to terminate in a distal end beyond the yoke;
a ring-engaging feature is at the distal end of the pin; and
a retaining ring is held on the pin by the ring-engaging feature,
whereby the ring retains the yoke on the pin prior to engagement of the yoke with the support member.

### Claim 18 (depends on 17)

The mounting assembly of claim 17 including a pair of adjustment pins for each yoke, one at each end of the yoke.

### Claim 19 (depends on 1)

The mounting assembly of claim 1 wherein:
the adjustable engagers are spaced brackets adjustably secured with respect to the opposing structure, each of the spaced brackets having a yoke for engagement with the support member; and
for each bracket, there is at least one adjustment pin holding the corresponding bracket at a selected distance with respect to the opposing structure.

### Claim 20 (depends on 19)

The mounting assembly of claim 19 including a pair of adjustment pins for each yoke, one at each end of the yoke.

### Claim 21 (depends on 19)

The mounting assembly of claim 19 wherein:
each adjustment pin has first and second ends and includes:
a threaded shank extending from the first end in threaded engagement with the opposing structure; and
a shaft portion extending from the threaded shank to the second end, the shaft portion having a ring-engaging feature at the second end; and
a retaining ring is held on the pin by the ring-engaging feature.

### Claim 22 (depends on 21)

The mounting assembly of claim 21 wherein each bracket has a pin-receiving aperture with the shaft portion of a corresponding pin extending therethrough, the ring retaining the bracket on the pin prior to engagement of the bracket with the support member.

### Claim 23 (depends on 21)

The mounting assembly of claim 21 wherein the first end of the pin is headless and has a wrench-engaging recess.

### Claim 24 (depends on 1)

The mounting assembly of claim 1 wherein the fulcrum is part of a fulcrum member having a mounting portion secured with respect to the fixture and an extension portion extending from the mounting portion to the fulcrum which protrudes from the extension portion.

### Claim 25 (depends on 24)

The mounting assembly of claim 24 wherein the fulcrum is shaped to limit lateral movement of the support member thereagainst.

### Claim 26 (depends on 25)

The mounting assembly of claim 25 wherein fulcrum includes a row of teeth configured to engage the support member.

### Claim 27 (depends on 26)

The mounting assembly of claim 26 wherein each of the adjustable engagers includes a bracket shaped to substantially conform to the shape of the support member.
