Mounting device for attaching a display device, a picture frame, or the like to a supporting structure
View Patent ↗A mounting device for attaching an object to a supporting structure includes a first member including at least one first magnet and a projection, the first member configured to be attached to a supporting structure, a second member including at least one second magnet and a recess to receive the projection, the at least one second magnet configured to be attracted to the at least one first magnet, and an electromagnet selectively operable to provide magnetic force to couple the first and second members together. A method of mounting an electronic display to a supporting structure also is disclosed.
1. A mounting device for attaching an object to a supporting structure, the mounting device comprising:
a first member including at least one first magnet and a projection, the first member configured to be attached to the supporting structure;
a second member including at least one second magnet and a recess to receive the projection, the at least one second magnet configured to be attracted to the at least one first magnet; and
an electromagnet selectively operable to provide magnetic force to couple the first and second members together;
wherein the electromagnet has a power supply operable to reduce the magnetic force produced by the electromagnet while power is supplied to the electromagnet.
2. The device of claim 1 , wherein:
the at least one first magnet comprises a plurality of first magnets disposed alternately with opposite polarities, and
the at least one second magnet comprises a plurality of second magnets disposed alternately with opposite polarities to match to the corresponding at least one first magnet.
3. The device of claim 1 , wherein the electromagnet is an electropermanent magnet.
4. The device of claim 1 , the at least one first magnet comprises a plurality of magnets arranged in at least one of a substantially circular layout, a substantially rectangular square layout, and a substantially cross-shaped layout.
5. The device of claim 1 , wherein the projection and the recess comprise part of a detent mechanism including a spring biasing the projection into the recess.
6. The device of claim 1 , wherein at least one of each of the first magnets and the second magnets has curved inner and outer surfaces disposed along a radius emanating from a center of circle formed by the first magnets.
7. The device of claim 1 , wherein the recess comprises a groove having a depth less than about 1 mm.
8. The device of claim 1 , wherein the object comprises one of an electronic display and a picture frame and the supporting structure comprises at least part of a wall.
9. The device of claim 1 , wherein at least one of the first and second members comprises a plate.
10. The device of claim 1 , wherein the second member comprises a portion of the object to be attached to the supporting structure.
11. The device of claim 10 , wherein the object comprises an electronic display and the electromagnet has the power supply separate from the electronic display.
12. A mounting device comprising:
a first member comprising magnets and a protrusion, the first member configured to be attached to a supporting structure; and
a second member comprising a portion of an electronic display to be attached to the supporting structure, the second member having a groove to receive the protrusion,
wherein at least one of the magnets is an electromagnet having a power supply separate from the electronic display.
13. The device of claim 12 , wherein the electromagnet is an electropermanent magnet.
14. The device of claim 12 , wherein the protrusion and the groove comprise part of a detent mechanism including a spring biasing the protrusion into the groove.
15. The device of claim 12 , wherein the groove has a depth less than about 1 mm.
16. The device of claim 12 , wherein at least one of the first and second members comprises a plate.
