Rapid installation and detachment device for flush mounting speaker on ceiling or wall
A rapid installation and detachment device for flush mounting speaker on ceiling or wall is composed of a hinge bracket, coil springs, gaiters, press fits, cushion springs and stop blocks. The above mechanisms are driven by the coil springs to rapidly and efficiently install a speaker on the hinge bracket. The detachment of the speaker never damages the surrounding surface material of the ceiling or wall. The device is applicable to all kinds of surface materials with different thickness.
1. Rapid installation and detachment device for flush mounting speaker on ceiling or wall basically comprising:
a hinge bracket with several guide sleeve bases provided on the surface thereof, a detent groove formed at one side of each guide sleeve base, and several guide hole bases provided on the surface of said hinge bracket, wherein said hinge bracket is to carry the whole weight of the installation;
a coil spring sleeved over said guide sleeve base and secured to said detent groove of said hinge bracket with its one end, and to a detent groove of a gaiter with the other end thereof;
said gaiter being sleeved over said coil spring, and having a notch formed on the upper surface of said gaiter with a detent groove provided at said notch side, a pawl being secured to the exterior edge of said gaiter and a guide hole formed in said gaiter;
a press fit covered on said gaiter and having a tapped hole formed at each of the two sides thereof with a screw set passing through so as to hold said press fit at the position on the guide hole base of said hinge bracket, a notch being formed at the center surface of said press fit with a tapped hole for said press fit to pass through, and a pawl being provided at one bottom edge of said press fit;
a cushion spring formed of a flat cap screw set with a compressed spring coiled on it, wherein said cushion spring passes through said gaiter and said press fit up and down and then is secured to a stop block;
said stop block set on said notch of said press fit and having a tapped hole in it, and a pawl extended from lower edge of both sides thereof so as to form a tenon and mortise joint with said notch on the surface of said gaiter thereby controlling said gaiter at its position before starting turning motion;
with this structure said hinge bracket can be settled at the desired location with an angle shaped spanner to actuate said cushion spring thereby liberating said gaiter form detention of said stop block, and then grabbing the surface material by turning 180° with said coiled spring.
2. The device of claim 1 , wherein a guide hole is provided in said guide sleeve base in said hinge bracket to let through said guide hole base.
3. The device of claim 1 , wherein said pawl jointed to said gaiter is in helical shape to grab various surface materials with different thickness, a detent groove is formed at the upper end of said helical pawl to trap a stopper provided at the lower end of said press fit to control the motion of said device after starting to operate, said helical pawl is provided with several grooves on its bottom surface to enhance the frictional force when grabbing the surface material.
4. The device of claim 1 , wherein said flat cap screw set can be unscrewed using a hexagonal spanner, after turning said pawl of said gaiter 180° to loosen it, said hinge bracket can be detached.
5. The device of claim 1 , wherein the numbers of said gaiter can be adjusted according to the speaker size.
6. The device of claim 1 , wherein said angle shaped spanner can be replaced with a pen holder, a piece of chop stick, a hexagonal spanner and the like rod shaped tool.
