Description

  The present invention relates to a floor panel.

  In a building in an office or the like, an OA floor is used as a so-called double floor that accommodates wiring of OA equipment and the like. In this OA floor, a space of a certain height is taken on the foundation floor to form another floor surface. Therefore, members such as wiring and a power source can be laid between the floor surface and the foundation floor.

  However, when a power supply is installed under the floor surface, an outlet such as a power cable or outlet connected to the power supply is placed on the floor surface in order to supply power to the electronic devices placed on the floor surface. It is necessary to put out. And since a power cable and an outlet will come out on a floor surface, the appearance of a room will worsen. Furthermore, if the power cable or the outlet is crushed by a fixture such as a chair or a shelf, the power cable or the outlet may be damaged.

  An example of a structure that prevents the power cable and the outlet from going out above the floor is, for example, the floor structure described in Patent Document 1. In this floor structure, a power feeding device that generates a high-frequency magnetic field is arranged under the floor material, and power is supplied in a non-contact manner to a power receiving device in a fixture placed on the floor surface. By adopting such a structure, there is no need to take out the power cable from under the floor toward the floor, preventing the design of the room from being damaged or damaging the power cable and other parts by damaging it. doing.

  However, in the structure as in Patent Document 1, a power transmission unit such as a power feeding device is embedded under a floor covering the room. For this reason, when changing the position of the power transmission unit in order to change the position of the power receiving device in accordance with the indoor layout change, it is necessary to peel off the flooring and take out the power transmission unit. In addition, since a power transmission unit such as a power supply device includes many electronic components such as a high-frequency inverter and a rectifier, there is a risk of failure. However, even in such a case, as in the case of changing the position of the power transmission unit, it is necessary to peel off the flooring and take out the power transmission unit every time a failure occurs. Therefore, there is a problem that it is difficult to change the position of the power transmission unit or to maintain the power transmission unit every time the power transmission unit is taken out to peel off the flooring.

  The present invention has been made to solve the above-described problems, and can supply power without disposing a member on the floor surface, can easily move the power transmission unit, and improve maintainability. It provides a possible floor panel.

In order to solve the above problems, the present invention proposes the following means.
A floor panel according to an aspect of the present invention is a floor panel that is disposed on a foundation floor to form at least a part of a floor surface that is configured to have a space on the foundation floor. A floor panel body in which an opening penetrating from the first surface facing upward with respect to the foundation floor when formed, and a power receiving unit attached to the opening and installed above the floor surface A storage box for storing a power transmission unit that supplies power in a non-contact manner, and a cover for closing the opening.

  According to such a configuration, power can be supplied to the power receiving unit in a non-contact manner by the power transmission unit accommodated in the storage box. Therefore, the power transmission unit and the power reception unit are provided to supply power to the power reception unit on the floor surface. The member to be connected is not placed on the floor. Therefore, the amount of members disposed above the floor surface can be reduced while supplying power to the power receiving unit disposed above the floor surface formed by the first surface. Moreover, a power transmission unit can be moved to arbitrary positions only by rearranging arrangement | positioning of a floor panel main body. Therefore, even when the position of the power receiving unit is changed in accordance with the layout change in a room such as an office, it is possible to easily move the power transmitting unit correspondingly. Furthermore, the power transmission unit can be easily replaced or repaired when the power transmission unit breaks down by removing the floor panel body or the cover.

  The floor panel may include a shield member made of a conductive material and arranged to cover the storage box.

  According to such a configuration, since the shield member is arranged so as to cover the storage box, electromagnetic waves generated from the power transmission unit in the storage box leak to the outside of the storage box, and the foundation floor and the floor surface It is possible to prevent the wiring arranged in the space between being affected.

  The floor panel may include a support member that supports the floor panel body with respect to the foundation floor.

  According to such a configuration, even if the strength of the floor panel main body is reduced by forming the storage box large, the floor panel main body is supported with respect to the foundation floor by the support member. The strength of the panel body can be secured. Therefore, the object placed on the floor panel main body stabilizes the object on the floor panel main body even when a load is generated from the first surface toward the foundation floor. Can be supported.

  Furthermore, in the floor panel, the storage box may be formed with a through-hole penetrating the storage box in and out.

  According to such a configuration, a member such as a cord for supplying electric power to the power transmission unit housed in the housing box is formed by forming the through-hole penetrating the housing box in and out. It can be laid in a space between the foundation floor and the floor without taking it out from the floor. Therefore, the amount of members arranged above the floor can be further reduced.

  According to the floor panel of the present invention, since the power transmission unit is accommodated in the storage box of the floor panel main body, electric power can be supplied without arranging members on the floor surface, and the power transmission unit can be easily moved and maintained. Can be improved.

  Thereafter, the power receiving unit 400 is installed on the cover unit 5 in a state where the main floor panel 300 and the floor panel 1 are arranged to form the floor surface 100b. Then, electric power is supplied from the power supply unit to the power transmission unit main body 41 via the power cord 43 to generate magnetic flux by the coil. Electric power is transmitted from the coil that is the power transmission unit main body 41 of the power transmission unit 4 to the coil of the power reception unit 400 by electromagnetic induction using this magnetic flux as a medium. Electric power is supplied to various devices such as OA equipment arranged on the floor via the power receiving unit 400 to which electric power is transmitted.

  In the floor panel 1 as described above, power can be supplied to the power receiving unit 400 in a non-contact manner by the power transmission unit 4 housed in the housing box 21, so that power is transmitted to supply power to the power receiving unit 400 on the floor surface 100 b. Members such as cables and outlets that connect the unit 4 and the power receiving unit 400 are not arranged on the floor surface 100b. Therefore, a member such as a cable or an outlet is disposed above the floor surface 100b in the vertical direction while supplying power to the power receiving unit 400 disposed above the floor surface 100b formed by the first surface 1a. The amount of can be reduced. Therefore, it can suppress that appearance deteriorates with members, such as a cable for supplying electric power, and an outlet, and the design property in a room is impaired. Moreover, since it is not necessary to arrange | position members, such as a cable, on the floor surface 100b, it can suppress that members, such as a cable, are stepped on and damaged by a fixture.

  Further, the power transmission unit 4 can be moved to an arbitrary position simply by rearranging the position of the floor panel body 2 with the main floor panel 300. Therefore, the position of the power transmission unit 4 in a room such as an office can be easily changed.

Furthermore, by removing the floor panel main body 2, the power transmission unit 4 can be easily taken out from the floor surface. Further, by removing the cover portion 5, it is possible to easily take out only the power transmission unit 4. Therefore, when the power transmission unit 4 breaks down, the power transmission unit 4 can be easily replaced or repaired.
As a result, electric power can be supplied without disposing a member on the floor surface 100b, the power transmission unit 4 can be easily moved, and the maintainability can be improved.

  In addition, since the shield member 3 is attached so as to cover the storage box 21 without a gap, electromagnetic waves generated from the power transmission unit 4 leak to the outside of the storage box 21, and the base floor 100 a and the floor surface 100 b It is possible to prevent the wiring C such as a LAN cable arranged in the space between the influences.

  Furthermore, even if the opening 20 becomes larger than the floor panel body 2 and the strength of the floor panel body 2 is reduced by forming the storage box 21 large, the floor panel body 2 is supported by the support member 6. Since it is supported from below in the vertical direction, the strength of the floor panel body 2 can be ensured. Therefore, when an object such as the power receiving unit 400 or a fixture is placed on the floor panel body 2 or a person gets on the floor panel body 2, the load is applied to the floor panel body 2 from the first surface 1a toward the foundation floor 100a. Even if this occurs, the object on the floor panel body 2 can be stably supported.

  Moreover, the power supply cord 43 for supplying electric power to the power transmission unit 4 accommodated in the accommodation box 21 by forming the through-hole 21c which penetrates the accommodation box side wall part 21a of the accommodation box 21 inside and outside. Can be laid in the space between the foundation floor 100a and the floor surface 100b without taking out the storage box 21 from the storage box 21 onto the floor surface 100b. Therefore, the amount of members arranged above the floor surface 100b can be further reduced.

Further, the present invention is not limited by the embodiments, and is limited only by the scope of the claims.

  Note that the transmission method of power from the power transmission unit 4 to the power supply unit is not limited to the electromagnetic induction type as in the present embodiment, and it is sufficient that the power can be transmitted in a contactless manner. For example, the electric power may be transmitted using a magnetic field resonance type that uses the same coil, or an electric field resonance / coupling type method that uses an electrode.

  Further, the storage box 21 is not limited to the structure formed to be recessed so as to form a rectangular space from the first surface 1a of the floor panel body 2 as in the present embodiment. What is necessary is just to be formed so that the power transmission unit 4 can be accommodated from the surface 1a. For example, it may be formed so as to be recessed from the first surface 1a so as to form a hemispherical space therein, or may be formed integrally with the floor panel body 2 and recessed from the first surface 1a.

  Furthermore, the shield member 3 that covers the storage box 21 is not limited to a structure that is attached to the inner surface of the storage box 21 as in the present embodiment, and electromagnetic waves and the like leak from the storage box 21 to the outside. Any structure that can reduce this is sufficient. For example, the shield member 3 may be arrange | positioned so that the storage box 21 may be covered from the outside. The storage box 21 and the floor panel main body 2 may be made of a conductive material such as metal, and the storage box 21 and the floor panel main body 2 itself may have a function as the shield member 3.

  Further, the main floor panel 300 and the floor panel 1 are not limited to the structure in which the four corners are supported by the support legs 200 as in this embodiment, and the floor surface 100b can be formed on the foundation floor 100a with a space therebetween. It suffices if they are arranged in such a manner.
