This application claims the benefit of and incorporates by reference U.S. Provisional Application No. 61/770,389 filed Feb. 28, 2013.


BACKGROUND
The present invention generally relates to the use of electronic devices mounted in ceilings and walls for wireless communication. More specifically, the present invention relates to an apparatus that mounts in a ceiling or wall and secures an electronic device within the ceiling or against a wall.
Commonly, the wireless equipment such as an access point or telemetry gateway is mounted on a desk top, attached to a wall, suspended from an acoustical tile ceiling gridwork, or placed above the acoustical tile ceiling. These methods of mounting do not physically secure the equipment, and do not provide for ease of installation and maintenance. Since the wireless equipment commonly has an antenna, the equipment must be mounted in such a way that the equipment and antenna is exposed to the room, so that the radio frequency may propagate into the room to be covered by the equipment. Such wireless equipment has become very popular for computer networking in schools, factories, public buildings and office buildings. A main part of a wireless system for a computer network is an access point. The access point is the unit which communicates directly with wireless devices carried by users. Access points are usually mounted in the ceilings of buildings to avoid the ugly look of the wires required to be hooked to the access point. The access point is an expensive piece of equipment which can be easily stolen from the ceiling of a building. Access points can be a variety of shapes and sizes, which depends on the manufacturer of the access point. The different shapes and sizes present a problem to finding a way to universally secure an access point in the ceiling or to a wall.
It is an object of the present invention to provide an apparatus that provides for secure mounting of an access point in a ceiling or to a wall, as well as other devices which could be mounted in a ceiling or to a wall.

DETAILED DESCRIPTION
The present invention is a mounting system to secure a device to a ceiling or to a wall of a building, as shown in FIGS. 1-33. FIGS. 1-16 show a ceiling embodiment. FIG. 1 shows a base 10, which acts as a ceiling tile. FIG. 1 shows the bottom of the base 10, which faces into the room of a building. The base 10 is usually sized and shaped to be a replacement for a ceiling tile used in a suspended ceiling system, but can be sized and shaped to simulate other types of ceilings. The base 10 in FIG. 1 is shown as a square, but could be any shape, depending on the shape of the ceiling tiles used in the suspended ceiling system. Generally, suspended ceiling systems use a grid of supports which hold tiles within the supports. The base 10 of FIG. 1 is shown where the bottom of the base 10 is an outside surface 12 of the base 10, which faces toward the inside of a room of a building when installed into the suspended ceiling system. The outside surface 12 is usually covered or painted to match the décor of the room, as it is seen by people in the room. Seen from the outside surface 12 of the base are a lock 14 and a device receiver plate opening 16. FIG. 2 shows an inside surface 18 of the base 10 with sides 20 extending upward from the inside surface 18. The base 10 can be secured in one of the open grids of a suspended ceiling system in a number of known methods, so that the base 10 cannot be removed without getting in between the roof and the suspended ceiling and using tools for the removal of the base 10 from the grid. The sides 20 of the base 10 can be used as part of the means of securing the base 10 in the open grid. FIG. 2 shows a secure cover 22 attached to the inside surface 18 of the base 10.
FIG. 3 shows an exploded view of the components of the secure cover 22. The secure cover 22 includes a top plate 24 and two cover sides 26. The top plate 24 includes two ends 28 extending down from the top plate 24. The two ends 28 of the top plate 24 extend downward towards the inside surface 18 of the base 10. The cover sides 26 are secured to the inside surface 18 of the base 10 using nuts 30 and threaded studs 32 extending upward from the inside surface 18. The top plate 24 is screwed to the cover sides 26 using screws 34 and screw holes 36 of both the cover plate 24 and cover sides 26 which align with each other. Together the cover plate 24 and cover sides 26 enclose the other components attached to the base 10. FIG. 3 also shows the lock 14, a lock stud 38, a cam plate 40, a nut 42, a lock plate 44 and guide pins 46. The lock plate 44 includes a cam plate opening 48 and two cam tabs 50. The lock 14 acts a key receiver and attaches to the base 10 through a lock hole 52. The lock 14 is to be accessed from the outside surface 12 with a key. The lock stud 38 extends up through the cam plate opening 48 and between the cam tabs 50. The lock stud 38 is rotated by turning the key in the lock 14. The cam plate 40 is attached to the lock stud 38 using the nut 42. Together the lock 14, lock stud 38, cam plate 40, nut 42 and cam tabs 50 act as a lock plate actuator to move the lock plate 44. FIG. 3 also shows lock holes 54 in the base 10.
FIG. 4 shows a device 56 attached to the mounting system of the first embodiment and extending outward for the outside surface 12 of the base 10. The device 56 is attached to a device receiver plate 58. FIG. 5 shows the device 56 attached to the device receiver plate 58 and exploded away from the base 10. The device receiver plate 58 has a device side 60 and a lock plate side 62. FIGS. 6-7 show the device side 60 of the device receiver plate 58. The device receiver plate 58 includes a device mount 64. The device mount 64 is attached to the device receiver plate 58 using a fastener, such as screws. The device mount 64 is made to mount properly to the particular device to be used, as devices are not universal. Therefore, the device mount 64 is the only part of the mounting system that has to be made specifically to fit the device 56. Thereby, allowing the other parts of the mounting system can be universal to the mounting of any device 56. The device receiver plate 58 includes a wire opening 68 to allow any needed wires from the device 56 to pass through. FIGS. 8-9 show the lock plate side 62 of the device receiver plate 58. The lock plate side 62 includes lock pins 70 extending out from the lock plate side 62. The lock pins 70 include a lock pin head 72 to aid in securing the device receiver plate 58 to the base 10.
As shown in FIG. 5, the lock plate 44 includes guide slots 74 to receive the guide pins 46 of the base 10. The lock plate 44 mounts over the guide pins 46 and slides along the guide pins 46. The guide pins 46 provide for uniform movement of the lock plate 44 forward and backward. The guide pins 46 are shown with guide pin heads 76 that fit in a head opening 78, which is a round hole at the end of each guide slot 74. The guide pin head 76 is larger than the guide pin 46 that fits into the guide slot 74, such that the guide pin 46 does not fall from the guide slot 74 due to the guide pin head 76 riding above the lock plate 44 around the guide slot 74. The guide pin 46 includes a shoulder 80 and a guide shaft 82. The guide shaft 82 extends up from the shoulder 80 and supports the guide pin head 76. The lock plate 44 rides on the shoulder 80 and the guide shaft 82 runs along the guide slot 74. The lock plate 44 also includes lock pin slots 84 with a head hole 86 at the end of the lock pin slots 84. The round head hole 86 of the lock pin slots 84 is a head opening to allow the lock pin head 72 of the lock pins 70 from the device receiver plate 58 to pass, as shown in FIG. 10. Movement of the lock plate 44 rearward caused the lock pin slots 84 to move along the lock pins 70 and under the lock pin head 72 of the lock pin 70, as shown in FIG. 11. The lock pin slots 84 hold the lock pins 70 in place by trapping the lock pin head 72 of the lock pin 70 above the lock plate 44. Holding the lock pin 70 in place secures the device receiver plate 58 to the base 10 and hence secures the device 56 to the base 10. The lock pin 70 includes a shoulder 88 and a guide shaft 90. The guide shaft 90 extends up from the shoulder 88 and supports the lock pin head 72. The lock plate 44 rides on the shoulder 88 and the guide shaft 90 runs along the lock slot 84.
FIGS. 12-16 show how the lock 14 works with the lock plate 44 to secure the device receiver plate 58 with the device 56 to the base 10. FIG. 12 shows the mounting system in the unlocked position. In the unlocked position, the lock pin heads 72 of the lock pins 70 are placed through the lock holes 54 of the base 10 from the outside surface 12 and into the head holes 86 of the lock plate 44. The cam plate 40 is against the forward cam tab 50. The cam plate 40 is shaped such that if part of the cam plate 40 is against one of the cam tabs 50, the cam plate 40 does not engage the other cam tab 50. Rotation of a key in the lock 14 rotates the lock stud 38 and hence the cam plate 40. FIGS. 13-15 show the larger part of the cam plate 40 rotating away from the forward cam tab 50 and toward the rearward cam tab 50. As the larger part of the cam plate 40 rotates toward the rear cam tab 50, the cam plate 40 pushes the lock plate 44 rearward. While the device 56 with device receiver plate 58 is under the device receiver plate opening 16, the movement of the lock plate 44 rearward causes the lock pin slots 84 to engage the lock pins 70 and hold the device receiver plate 58 in place. FIG. 16 shows the larger part of the cam plate 40 against the rear cam tab 50. When the cam plate 40 is against the rear cam tab 50, the lock plate 44 is in the full lock position and the key of the lock 14 can be removed. Once the key is removed, the device 56 cannot be removed without the use of the key.
FIGS. 17-38 show a wall embodiment of the present invention. FIGS. 17-19 show the assembled mounting system for walls. FIG. 18 shows a device 56 attached to the mounting system of FIG. 17.

One of the sides 96 includes a lock opening 102 to receive and mount the lock 14 which receives a key 104. The sides 96 are shown with as a triangle shape to reduce the overall size of the wall embodiment, but could be other shapes, such as a rectangular shape. The cover plate 94 includes side flanges 106 and end flanges 108. The side flanges 106 fit over the sides 96 of the base 92. The first end flange 108 seals off the one end of the base 92. The second end flange 108 aids in sealing the base 92 off at the mounting flanges 98. The cover plate 94 can be screwed to the sides of the base using holes 110 in the side flanges 106 of the cover plate 94. Rivets can replace the screws 112 for more security after the base 92 is mounted to the wall using the wall mount flanges 98. The combination of the cover plate 94 and base 92 prevent direct access to the lock plate 44 and acts as a box shaped enclosure. The base 92 could also include four rectangular sides extending up from the base 92 instead of the wall flanges 98 and sides 96 to make a rectangular box shape with the cover plate 94 engaging the four sides.
The lock plate 44 includes guide slots 74, lock pin slots 84 and a lock flange 114. The base 92 includes guide pins 46 with guide pin heads 76 extending upward from the inside surface 18 of the base 92. The guide slots 74 of the lock plate 44 allow for the lock plate 44 to be slipped over the guide pins 46 at a head opening 78 of the guide slot 74 and held in position by the guide pins 46 so the lock plate 44 can move forward and rearward along the guide pins 46. The guide pins 46 include a shoulder 80 and guide shaft 82 similar to the ones of the ceiling embodiment. The device 56 that is to be mounted to the wall embodiment is attached to the same device receiver plate 58 shown in FIGS. 6-9 of the ceiling embodiment. FIG. 19 shows the device 56 attached to the device receiver plate 58 and exploded away from the base 92. The device receiver plate 58 is the same as shown in FIGS. 6-7, which show the device side 60 of the device receiver plate 58. FIGS. 8-9 show the lock plate side 62 of the device receiver plate 58. FIGS. 20-21 show lock holes 54 in the base 92. FIG. 22 shows the lock pins 70 extending up into the base 92 and through the head holes 86 of the lock pin slots 84. FIG. 23 shows the lock plate 44 after it has been move forward toward the locked position, where the lock pins slots 84 have engaged and captured the lock pin heads 72 of the lock pins 70. The lock pins 70 include a shoulder 88 and guide shaft 90 similar to the ones of the ceiling embodiment.
FIGS. 20-21 show the lock 14 as a key receiver, which is shown as a lock cylinder 116 that receives a key 104. A cam plate 40 is connected to the lock cylinder 116, which turns when the key 104 is turned. The cam plate 40 includes a cam shaft 118 extending from the cam plate 40. Together the lock cylinder 116, cam plate 40 and cam shaft 118 act as a lock plate actuator. The cam shaft 118 includes a screw hole 120.
