Abstract
An apparatus includes a wall defining an opening. A first bracket is connected to the wall and defines a first channel. A second bracket is located across the wall opening from the first bracket and defines a second channel. A hinge connects the second bracket to the wall such that the second bracket can pivot from a first position in which the second channel is open toward the wall opening to a second position in which the second channel is open toward the first channel. The brackets are configured to retain the lens in an installed position in which the lens extends across the wall opening, the first bracket captures a first end of the lens, the second bracket is in its second position, and the second channel captures a second end of the lens.
Claims35
An apparatus comprising:
- a wall defining an opening;
- a first bracket connected to the wall and defining a first channel;
- a second bracket located across the wall opening from the first bracket and defining a second channel;
- and
- a hinge connecting the second bracket to the wall such that the second bracket can pivot from a first position in which the second channel is open toward the wall opening to a second position in which the second channel is open toward the first channel;
- the brackets being configured to retain a lens in a removably installed position in which the lens extends across the wall opening, the first channel captures a first end of the lens, the second bracket is in its second position, and the second channel captures a second end of the lens.
An apparatus comprising:
- a wall defining an opening;
- a first bracket defining a first channel;
- a first hinge connecting the first bracket to the wall;
- a second bracket located across the wall opening from the first bracket and defining a second channel;
- and
- a second hinge connecting the second bracket to the wall;
- the brackets being configured to retain a lens in a removably installed position in which the lens extends across the wall opening, the first bracket captures a first end of the lens, and the second bracket captures a second end of the lens.
An apparatus comprising:
- a wall defining an opening;
- a first bracket connected to the wall and defining a first channel;
- and
- a second bracket located across the wall opening from the first bracket, defining a second channel and flexibly connected to the wall by a hinge that enables the second bracket to pivot from a first position in which the second channel is open toward the wall opening to a second position in which the second channel is open toward the first channel;
- the brackets being configured for a lens to be brought into a removably installed position by inserting the lens into the first channel, and then pivoting the lens about the first channel toward and into the second channel for the lens to extend across the wall opening.
An apparatus comprising:
- a wall having an opening defined by two opposite end edges of the wall and two opposite side edges of the wall;
- two brackets, each flexibly connected to the wall adjacent a respective end edge by a hinge and defining a channel;
- two abutment structures, each extending from the wall adjacent a respective side edge;
- and
- a lens having two opposite ends and two opposite sides, being mountable in a removably installed position in which the ends of the lens are captured in respective brackets, and lateral movement of the lens is limited by abutment of the sides against respective abutment structures.
An apparatus comprising:
- a wall defining an opening;
- a first bracket connected to the wall and defining a first channel;
- and
- a second bracket located across the wall opening from the first bracket, defining a second channel and flexibly connected to the wall;
- the brackets being configured to retain a lens in a removably installed position in which the lens extends across the opening with one end of the lens extending beyond the opening into the first channel and an opposite end of the lens extending beyond the opening into the second channel.
An apparatus comprising:
- a wall defining an opening;
- a first bracket connected to the wall and defining a first channel;
- and
- a second bracket located across the opening from the first bracket, defining a second channel, and flexibly connected to the wall to be pivotable from a first position in which the second channel is open toward the opening to a second position in which the second channel is open toward the first channel;
- the brackets being configured to retain a lens in a removably installed position in which the lens extends across the wall opening and is captured in the first and second channels.
