Abstract

Provided are a wireless display mount capable of facilitating changes to the arrangement for the mount without, for example, having to rewire the power wire; and a wireless display system capable of highly efficient supply of electricity to a wireless display. A wireless display mount supplies electricity to a wireless display wirelessly via electromagnetic induction and includes a case, a power wire and a connection terminal. The case has a cavity in-between the power wire where a wireless display may be installed. A wireless display system includes a wireless display, and wireless display mount. The wireless display has a loop coil. The wireless display mount has a housing for housing the power wire, disposed adjacent to the loop coil and formed at a location separated from the mounting surface of the wireless display mount.

Claims

1. A wireless display mount which supplies electricity to a wireless display wirelessly via electromagnetic induction, the wireless display mount comprising:

a band-shaped case;

a power wire having a prescribed length and wired to and arranged in the case along the longitudinal direction of the case, the power wire is spaced apart in the width direction of the case; and

a connection terminal connecting both ends of the power wire with another power wire, wherein the case has a space between the spaced-apart power wire into which a wireless display may be installed.

2. The wireless display mount according to claim 1 wherein a plurality of the power wires is provided.

3. The wireless display mount according to claim 1 wherein the power wire is housed at a position that is separated from the mounting surface of the case by as much as a prescribed distance.

4. The wireless display mount according to claim 2 wherein the wiring for the plurality of power wires in the case is such that the power wires are arranged one on top of the other in a direction intersecting at right angles with the mounting surface of the case.

5. A wireless display mount apparatus comprising:

a wireless display mount according to claim 1;

a looped terminating member including a power wire and a connection terminal, the terminating member connected between power wires on one end of the wireless display mount; and

a starting member including a power wire and a connection terminal, the starting member connected between power wires on the other end of the wireless display mount and outputs an alternating current,

wherein the power wires in the wireless display mount, the terminating member, and the starting member configure a coil with at least one turn by respective connections of the connection terminals.

6. A wireless display system comprising:

a wireless display mount according to claim 1 and a wireless display, wherein

the wireless display has a loop coil inside,

the wireless display mount has a cavity which houses and secures a housing section which houses the power wire of the power supply means inside the band-shaped case and the wireless display between the power wires, and

the housing section is disposed at a position that is near the loop coil of the wireless display when the wireless display is installed in the cavity of the wireless display mount, and is formed at a position that is away from the mounting surface of the wireless display mount.

7. The wireless display system according to claim 6 wherein the housing section is formed in the case on both side sections in the width direction separated by a prescribed distance from near end sections that make contact with the mounting surface;

and the cavity is formed between the housing sections which are on both sides.

8. The wireless display system according to claim 7 wherein the loop coil in the wireless display is disposed opposite at substantially the center of the height of the power wire that is housed in the housing section.

9. The wireless display system according to claim 6 wherein the wireless display includes an electromagnetic wave absorber and a printed circuit board;

and the electromagnetic wave absorber is provided between the loop coil and the printed circuit board.

10. The wireless display system according to claim 6 further comprising:

a looped terminating member including a power wire and a connection terminal, the terminating member connected between power wires on one end of the wireless display mount; and

a starting member including a power wire and a connection terminal, the starting member connected between power wires on the other end of the wireless display mount and outputs an alternating current;

wherein the power wires in the wireless display mount, the terminating member, and the starting member configure a coil with at least one turn by respective connections of the connection terminals.

12. The wireless display mount according to claim 2 wherein the power wire is housed at a position that is separated from the mounting surface of the case by as much as a prescribed distance.

13. The wireless display system according to claim 7 wherein the wireless display includes an electromagnetic wave absorber and a printed circuit board;

and the electromagnetic wave absorber is provided between the loop coil and the printed circuit board.

14. The wireless display system according to claim 8 wherein the wireless display includes an electromagnetic wave absorber and a printed circuit board;

and the electromagnetic wave absorber is provided between the loop coil and the printed circuit board.

11. A wireless display system comprising a wireless display and a wireless display mount provided with a securing means for securing the wireless display and a power supply means for supplying electricity to the wireless display wirelessly via electromagnetic induction, wherein

the wireless display has a loop coil inside,

the wireless display mount has a cavity which houses and secures a housing section which houses the power wire of the power supply means inside the band-shaped case and the wireless display between the power wires, and

the housing section is disposed at a position that is near the loop coil of the wireless display when the wireless display is installed in the cavity of the wireless display mount, and is formed at a position that is away from the mounting surface of the wireless display mount.
