## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an in-ceiling speaker mount, and more particularly to an easy-mount in-ceiling speaker mount capable of holding an in-ceiling speaker on a ceiling when the in-ceiling speaker is mounted upwardly in a mounting hole of the ceiling.
2. Description of the Related Art
General buildings are built to have a paging and voice alarm system having a plurality of speakers mounted in each floor and partition for paging and emergency announcement. Conventionally, an in-ceiling speaker can be mounted in a mounting hole formed through a ceiling for the purposes of saving space and improving aesthetic appearance.
With reference to FIG. 6, a conventional in-ceiling speaker mount has an annular wall 80, multiple elastic holders 90 and a speaker hood 100. The annular wall 80 has an annular flange 81 formed on and protruding radially from a bottom of the annular wall 80. The elastic holders 90 are mounted on the annular flange 81, and each elastic holder 90 has a torsion spring 92 and a spring holder 91. The spring holder 91 has a hood 912 formed on and protruding from a top of the spring holder 91 for retaining a movable end 922 of the torsion spring 92 in the hood 912. The speaker hood 100 is securely mounted through the annular wall 80 and has a lower opening 120. An in-ceiling speaker is mounted in the speaker hood 100 through the lower opening 120.
The conventional in-ceiling speaker and mounts can be mounted as follows. The annular wall 80 is inserted into a mounting hole of a ceiling until the annular flange 81 abuts against a bottom of the ceiling. Meanwhile, the elastic holders 90 are located above the ceiling. The movable end of each torsion spring 92 can be unlocked from a corresponding hook 912 by being accessed through the annular wall 80 and automatically springs back to abut against and press the ceiling due to a torque of the torsion spring 92. The speaker hood 100 is securely and upwardly mounted through the annular wall 80. The in-ceiling speaker is securely mounted in the speaker hood 100 through the lower opening 120.
The foregoing mounting procedures are inconvenient and time consuming. Besides, each in-ceiling speaker mount has two separate parts, namely, the annular wall 80 and the speaker hood 100, which consume more material to implement.
SUMMARY OF THE INVENTION
An objective of the present invention is to provide an easy-mount in-ceiling speaker mount capable of fastening an in-ceiling speaker on a ceiling when the in-ceiling speaker is mounted upwardly in a mounting hole of the ceiling.
To achieve the foregoing objective, the easy-mount in-ceiling speaker mount has multiple fastening units adapted to be mounted on a top of an in-ceiling speaker. Each fastening unit has a base frame, a torsion spring, a pivoting member, a slider plate and a spring holder.
The base frame has a narrow bottom and a wide top. The narrow bottom has two parallel walls respectively formed on and protruding forwardly from two opposite sides of the narrow bottom. Each parallel wall has multiple through holes longitudinally formed through the parallel wall and respectively aligning with the through holes of the other parallel wall. The wide top has a pivot base and two slider guides. The pivot base is formed on and protrudes forwardly from the front of the wide top. The slider guides are mounted on a portion of the wide top protruding beyond the narrow bottom in the longitudinal direction.
The torsion spring is securely mounted between the parallel walls by selectively mounting a pin through two corresponding through holes of the parallel walls and the torsion spring, and has a free end and a fixed end. The fixed end abuts against a front of the narrow bottom.
The pivoting member has a pivot body, a fixing element and a contact rod. The pivot body is pivotally mounted on the pivot base of the base frame and has two ends opposite to each other. The fixing element is mounted in one of the ends of the pivot body. The contact rod is mounted on the other end of the pivot body.
A slider plate has a sliding slot, a tag and a ceiling support. The sliding slot is longitudinally formed through the slider plate for the slider guides to be mounted within the sliding slot and longitudinally movable relative to the sliding slot. The tag is formed on and protrudes from a top of the slider plate toward the pivoting member, and is located above the contact rod of the pivoting member. The ceiling support is formed on and protrudes forwardly from a bottom of the slider plate.
The spring holder is pivotally mounted between the parallel walls of the base frame by penetrating the pin through a bottom of the spring holder and the torsion spring, and has a front wall and a rear flange. The front wall abuts against the free end of the torsion spring subjected to a preset torque. The rear flange is formed on and protrudes transversely from a rear edge of the sidewall adjacent to the fixing element of the pivoting member toward the slider plate, and is blocked by the fixing element of the pivoting member.
When the easy-mount in-ceiling speaker mount is mounted upwardly through an opening of a ceiling, the ceiling support of the slider plate first holds a bottom of the ceiling. Meanwhile, the base frame of each fastening unit is pushed upwardly relative to the sliding slot of the slider plate, and the pivoting member is pressed and pivoted downwardly by the tag of the slider plate while the fixing element of the pivoting member is pivoted upwardly. When the rear flange of the spring holder is no longer blocked by the fixing element, the spring holder is pivoted by the preset torque of the torsion spring to abut against and hold a top of the ceiling in completion of the mounting of the in-ceiling speaker. The mounting procedures of the speaker mount can be easily achieved by simply pushing it upwardly through a ceiling.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
