  A power generation device using a piezoelectric element that generates electricity by pressure fluctuation caused by the movement of an object, and by providing a stopper that prevents excessive deformation of the piezoelectric element, the piezoelectric element is not damaged even by strong pressure fluctuation A pressure-sensitive power generator capable of generating power is known (Patent Document 1).

JP 2007-97278 A

The pressure-sensitive power generator described above has durability and is expected to be effectively used in various fields.
For example, the above-mentioned pressure-sensitive power generation device is built in the flooring, and using the electric power generated by the pressure fluctuation generated on the flooring top surface by walking or the like, the electric wave is transmitted, or the counter is activated and the number of pressure fluctuations ( The number of times of load load, etc.) can be stored, or the LED that is internally or externally mounted on the flooring can be made to emit light. Further, the magnitude of the pressure fluctuation applied and the acceleration of the pressure fluctuation can be detected based on the magnitude of the electromotive force. For this purpose, it is necessary to efficiently transmit the pressure fluctuation to the pressure-sensitive power generator and to protect the pressure-sensitive power generator more appropriately from the pressure fluctuation.

  The flooring with a built-in pressure-sensitive power generation device stores the pressure-sensitive power generation device in a watertight manner in the space between the top and bottom surfaces of the flooring, and uses a flexible plate or a flexible plate as the top surface. By using the pressure fluctuation generated in the upper surface of the floor material by walking or the like to the pressure-sensitive power generation device and generating power, and using a rigid or hard plate material as the lower surface body, the pressure-sensitive power generation device It is normal to adopt a configuration that protects.

However, the flooring material having such a structure is particularly difficult when the pressure sensing power generation device has a plan view area that is considerably smaller than the flooring area and has a plurality of pressure sensing power generation devices built therein. The pressure-sensitive power generation device arranged below the raised part is sufficiently transmitted with the pressure fluctuations that occur in and around the part where the top body is stepped. Since pressure fluctuations are not sufficiently transmitted to other pressure-sensitive power generators that do not exist below the rare part, it is difficult to generate power efficiently, and the power generation efficiency of the pressure-sensitive power generator built in the flooring as a whole is reduced. It's hard to say good.
In addition, the flexible and flexible plate material used as the upper body has a problem that the pressure-sensitive power generation device, which is a precision instrument, cannot be protected from excessive pressure and impact force, and is locally applied to the plate material by walking. Since deformation (bending, sinking, etc.) occurs, there is also a problem that the feeling of walking is not good.
Furthermore, since a rigid or hard plate material is used as the lower surface, if there is unevenness or unevenness on the floor base that is the laying surface for laying the flooring, due to unevenness or unevenness when laying the flooring, There is also a problem that the flooring is tilted or unstable.

  The present invention has been made in view of the above circumstances, and the problem to be solved is that the power generation efficiency of the entire pressure-sensitive power generation device housed inside the flooring material is good, Since no bending occurs locally, it gives a good feeling of walking, can protect the pressure-sensitive power generation device from excessive pressure and shock pressure fluctuations (load), and the state of the floor surface (irregularity and It is to provide a power generation floor material that can be laid without choosing whether or not it is uneven.

In order to solve the above problems, a power generation flooring according to the present invention includes an upper surface body, a lower surface body, a bonding wall that bonds the upper surface body and the lower surface body, the upper surface body, the lower surface body, and the bonding wall. A power generation flooring provided with one or more pressure-sensitive power generation devices arranged in a storage portion formed by the above, wherein the lower surface body has flexibility and has a convex portion protruding downward. It is characterized by.
Here, “flexibility” means a property that is flexible and can be bent or bent by applying pressure, and when the pressure is released, it returns to its original shape by repulsion. Those that do not deform or hardly deform even when a constant pressure of the human walking pressure is applied, those that retain the deformed shape as it is even if the pressure is released after being deformed by applying a certain pressure, or the original The thing which hardly returns to a shape is not included in the thing which has flexibility.

In the power generation flooring of the present invention, it is desirable that the upper surface body is harder and more rigid than the lower surface body. Here, “rigidity” means a property that does not deform or hardly deforms even when a constant pressure such as human walking pressure is applied.
Further, it is desirable that a projection region from above the convex portion overlaps with a projection region from above the pressure-sensitive power generation device, and an area of the former projection region is larger than an area of the latter projection region.
The pressure-sensitive power generation device is provided directly or indirectly in contact with the upper surface of the lower surface body, and the upper portion of the device and the lower surface of the upper surface body are separated from each other, or the pressure-sensitive power generation device is It is desirable to be provided in direct or indirect contact with the lower surface of the body, and the lower part of the device and the upper surface of the lower surface body are spaced apart.

The power generation flooring of the present invention, for example, when walking pressure is applied to the upper surface body from above, the entire flooring material tends to move downward, but the downward convex portion of the lower surface body is laid by the floor basement. Since the lower surface body having flexibility is supported from below, the convex portion forming portion and the peripheral portion thereof are bent upward and deformed, and are pushed upward relatively. Therefore, the pressure-sensitive power generation device disposed in the storage portion between the upper surface body and the lower surface body is sandwiched between the convex portion forming portion of the lower surface body and its peripheral portion and the upper surface body, and the walking pressure is effectively pressure-sensitive. Since it is transmitted to the power generation device, the pressure sensitive power generation device can generate power efficiently due to the pressure fluctuation. When the convex portion forming portion of the lower surface body and its peripheral portion are flexibly deformed as described above, a force (repulsive force) to return to the original shape is generated in the flexible lower surface body, so that walking At the same time as the pressure is removed, the bottom body is restored to its original shape, and the pressure-sensitive power generation device is depressurized, and the pressure-sensitive power generation device efficiently generates power due to the pressure fluctuation, and the power generation flooring is in the initial state. Return.
In addition, when the lower surface body is flexible and has a convex portion protruding downward like the power generation floor material of the present invention, there are irregularities and unevenness on the floor base that is the laying surface. However, since the unevenness and unevenness of the floor base can be absorbed by the lower surface body, the floor base can be laid regardless of the state of the floor base.

  In the power generation flooring of the present invention, if the upper surface body is harder and more rigid than the lower surface body, even if the user walks on the upper surface body, deformation such as unequal subsidence or deflection is caused by the upper surface body. Since it does not occur locally, it has excellent walking sensation, and the pressure-sensitive power generation device placed in the housing between the upper and lower bodies is used for shock pressure fluctuation (load) and excessive Can be protected from excessive pressure.

  In the power generation device of the present invention, the projection region from above the convex portion overlaps the projection region from above the pressure-sensitive power generation device, and the area of the former projection region is larger than the area of the latter projection region. When the walking pressure is applied to the upper surface body, the convex portion forming portion and the peripheral portion of the lower surface body are bent and deformed, and all the pressure-sensitive power generation devices are surely relatively pushed up, so that the lower surface body and the upper surface body are Since it is pinched by the body and the pressure fluctuation is transmitted to all the pressure-sensitive power generation devices without loss, the power generation efficiency of the pressure-sensitive power generation device as a whole can be improved.

And in the power generation flooring of the present invention, the pressure-sensitive power generation device is provided directly or indirectly in contact with the upper surface of the lower surface body, and the upper portion of the device and the lower surface of the upper surface body are separated from each other, or The pressure-sensitive power generation device is provided directly or indirectly in contact with the lower surface of the upper surface body, and the lower portion of the device and the upper surface of the lower surface body are separated from each other. By separating from the upper surface of the lower surface body, the initial shock pressure fluctuation (pressurization) applied to the floor material surface (upper surface body) can be reduced, and the pressure-sensitive power generation device can be more reliably protected.
Further, when the upper or lower portion of the pressure-sensitive power generation device and the lower surface of the upper surface body or the upper surface of the lower surface body are separated from each other, when the power generation flooring is left on the floor base that is a laying surface, the lower surface body is The fear of a decrease in power generation efficiency of the pressure-sensitive power generation device due to the weight of the material can be eliminated. This is because, when the upper surface and the lower surface are both in contact with the pressure-sensitive power generation device, the lower surface is caused by the weight of the power generation floor when the power generation floor is placed on the floor base. However, the pressure due to the weight of the power generation flooring is added to the pressure-sensitive power generation device, so the pressure-sensitive power generation device always has its own weight. Thus, the corresponding pressure cannot contribute to power generation. On the other hand, when the pressure-sensitive power generation device and the lower surface of the upper surface body or the upper surface of the lower surface body are separated as in the present invention, the weight of the power generation flooring and the repulsive force against the pressure of the lower surface body are balanced, It is possible to prevent pressure from being applied to the pressure-sensitive power generator due to the weight of the power generation floor material, and the power generation efficiency is not reduced. In addition to the above, when the components are separated as in the present invention, an effect of being able to absorb errors in molding accuracy and assembly accuracy of each member of the flooring can be expected.

  Hereinafter, an embodiment of a power generation flooring according to the present invention will be described with reference to the drawings.

1 is a schematic plan view showing an embodiment of a power generation flooring according to the present invention, FIG. 2 is a schematic cross-sectional view taken along the line AA in FIG. 1, and FIGS. 3 to 9 and FIGS. FIG. 10 is a schematic cross-sectional view showing still another embodiment of the power generation flooring according to the present invention, FIG. 10 is a schematic cross-sectional view and schematic half-bottom view showing still another embodiment of the power generation flooring according to the present invention, and FIG. It is a schematic exploded perspective view of a pressure-sensitive power generation device.
In the schematic cross-sectional views shown in FIG. 2 to FIG. 17, the hatching that rises to the right represents a member having flexibility, and the hatching that rises to the left is more rigid than the bottom body or is a hard material having rigidity. The vertical hatching represents either a member having flexibility or a member having rigidity.

The power generation flooring of the embodiment shown in FIG. 1 and FIG. 2 includes a flat upper surface body 1, a flat lower surface body 2, and a joining wall 3 that joins the upper surface body 1 and the lower surface body 2 at the periphery. And one or more (four in this embodiment) pressure-sensitive power generation devices 5 arranged in the storage space 4 formed by the upper surface body 1, the lower surface body 2, and the joining wall 3. The lower surface body 2 has flexibility, and includes a convex portion 6 protruding downward on the lower surface.
As described above, the “flexibility” of the lower surface body 2 is soft and can be bent or bent by applying pressure. When the pressure is released, the repulsive force returns to its original shape. It means the nature of returning, and it does not deform even if a constant pressure of human walking pressure is applied, or it does not deform almost, or it deforms even if the pressure is released after deforming by applying a constant pressure. Those that are held as they are or those that hardly return to their original shapes are not included in the flexible ones.

  As the material of the lower surface body 2, a material having the above-described flexibility, easily deformed when a pressure equivalent to human walking pressure is applied, and rich in repulsive force is preferable. A plate-like body made of a synthetic resin such as soft vinyl chloride or polyolefin having a modulus of elasticity of about 500 to 5000 MPa, or rubber, or a foam thereof, is preferably used, and a plate-like shape obtained by combining these layers. A laminate is also used. Further, the Young's modulus of the lower surface body 2 is preferably about 1000 to 3500 MPa.

  In the lower surface body 2 having a Young's modulus lower than the above range, when the power generation flooring is laid on a laying surface such as a floor base, the convex portion forming portion of the lower surface body 2 and its peripheral portion are bent upward and deformed by the weight of the power generation floor material. Even if the walking pressure is not applied to the upper surface body 1, the pressure-sensitive power generation device 5 is slightly pinched between the upper surface body 1 and the lower surface body 2 from the beginning, and the amount of deformation necessary for power generation of the pressure-sensitive power generation device 5 is secured. In some cases, it may be difficult to generate power reliably and sufficiently. In addition, the lower surface body 2 made of a material whose Young's modulus exceeds the above range is difficult to bend and deform due to human walking pressure, so that it is difficult to generate power by applying pressure fluctuation to the pressure-sensitive power generation device. The material of the lower surface body 2 is preferably soft. If the lower surface body 2 is soft, the pressure-sensitive power generation device can be protected by relaxing and absorbing shock pressure fluctuation.

  Although the thickness of the lower surface body 2 is not particularly limited, it is preferably about 1 to 5 mm in order to reliably transmit the pressure fluctuation to the pressure-sensitive power generation device with sufficient flexibility to generate sufficient power. When the thickness range is exceeded, the flexibility of the lower surface body 2 is lowered, so that it becomes difficult to sufficiently transmit pressure fluctuations during walking to the pressure-sensitive power generation device 5, and when the thickness range becomes thinner than this thickness range. Since the strength of the lower surface body 2 is reduced, for example, when a power generation flooring is laid on a laying surface on which pebbles and the like exist and a walking pressure is applied, the lower surface body 2 and the pressure-sensitive power generation device 5 are moved by the pebbles pushed up from below. May cause damage.

The upper surface body 1 may be formed of a material having flexibility or flexibility, but is preferably formed of a material having rigidity higher than that of the lower surface body 2 described above. As described above, the “rigidity” of the upper surface body 1 means the property that it does not deform or hardly deforms even when a constant pressure such as a human walking pressure is applied.
As the upper surface body 1 having such rigidity, a synthetic resin such as hard vinyl chloride resin or polycarbonate resin, hard rubber, or a plate-like body formed of metal, ceramics, stone, wood or the like is used. From the viewpoint of walking feeling and protection of the pressure-sensitive power generation device 5, those having a Young's modulus (or elastic modulus) of about 0.2 to 700 GPa are preferably used, and more preferably 0.2 to 250 GPa. It is done. Although the thickness of the upper surface body 1 is not specifically limited, From a viewpoint of rigidity or intensity | strength, it is desirable that it is about 1-20 mm.

That is, if the upper surface body 1 has the above-described rigidity and the Young's modulus is within the above range, even if a human walks on the upper surface body 1, the upper surface body 1 sinks unequally or bends. Is not generated locally, so that the walking feeling is excellent, and the pressure-sensitive power generation device 5 disposed in the accommodating portion 4 between the upper surface body 1 and the lower surface body 2 is subjected to shock pressure from above. It is possible to reliably protect against fluctuations (load) and excessive pressure.
And from the viewpoint of protecting the pressure-sensitive power generation device, the upper surface body 1 is preferably hard, that is, a material having higher hardness than the lower surface body 2. That is, it is assumed that the upper body 1 is higher in rigidity than the lower body 2 and is made of a material having higher hardness, so that impact or / and local pressure fluctuation (load) is applied to the floor material surface. However, the pressure-sensitive power generation device is prevented from being directly added thereto, and the flexibility and soft nature of the lower surface body 2 relaxes and absorbs them, so that the protective effect of the pressure-sensitive power generation device is synergistically improved. It is.

  Moreover, on this upper surface body 1, in order to aim at the improvement of design nature, anti-slip property, antifouling property, etc., protection of the pressure-sensitive power generation device 5 from excessive impacts, impact mitigation when a pedestrian falls, etc. Various floor materials made of soft or hard vinyl chloride resin, polyolefin resin, etc., for cosmetics, antislip, antifouling, shock absorption, etc. may be stacked and adhered and integrated with an adhesive.

  The joining wall 3 that joins the upper surface body 1 and the lower surface body 2 at the peripheral edge thereof is made of a material that has the same flexibility as the lower surface body 2 in the power generation floor material shown in FIG. Although it is formed, it is made of a material that has the same rigidity as that of the upper surface body 1 and does not deform even when a constant pressure such as walking pressure is applied, or is difficult to deform, like the power generation flooring shown in FIG. It may be formed. When the joining wall 3 is formed of a flexible material, the impact force applied to the upper surface body 1 can be reduced, and when the joining wall 3 is formed of a rigid material, the upper surface body 1 is The applied walking pressure is transmitted to the peripheral portion of the lower surface body 2 without loss, and the convex portion forming portion of the lower surface body 2 and its peripheral portion are flexed and deformed relatively upward so that the pressure-sensitive power generation device 5 is connected to the upper surface body 1 and the lower surface. By pinching with the body 2, it is possible to reliably generate power with the pressure fluctuation.

  It is important that the upper surface body 1 and the lower surface body 3 are joined in a watertight manner in order to protect the pressure-sensitive power generation device 5 from water intrusion. Therefore, the upper surface and the lower surface of the joining wall 3 are water-tightly bonded to the lower surface of the upper surface body 1 and the upper surface of the lower surface body 2 with an adhesive, or water-tight by means such as heat welding, ultrasonic welding, and high-frequency welding. It is desirable to weld.

It is also desirable to apply a sealing material between the upper surface body 1 and the lower surface body 2 and cure it to form the bonding wall 3 at the same time as the upper surface body 1 and the lower surface body 1 are watertightly bonded.
As the sealing material, a sealing material made of a one-component or two-component reactive silicone resin, a modified silicone resin, a urethane resin, a polysulfide resin, an acrylic resin, or the like is used. In particular, the 25% modulus is 0.1 to 1.. A slightly soft one adjusted to a range of 5 N / mm ² is preferably used. The value of 25% modulus was measured at a tensile strength of 100 mm / min using a specimen molded in the shape of dumbbell No. 2 having a thickness of 2 mm according to JIS K 6251.

  When the joining wall 3 is formed of such a sealing material, in addition to ensuring the water tightness of the storage portion 4 that houses the pressure-sensitive power generation device 5, the joining wall is applied when an impact force is applied to the upper surface body 1. 3 can be slightly compressed and deformed up and down to absorb the impact force, and the walking pressure acting on the upper surface body 1 is transmitted to the peripheral portion of the lower surface body 2 with almost no loss, and the convex portion of the lower surface body 2 The forming portion and its peripheral portion are bent upward and deformed relatively, and the pressure-sensitive power generation device 2 can be sandwiched between the upper surface body 1 and the lower surface body 2 to reliably generate power.

  Further, the joining wall 3 may be integrally formed by projecting downward from the peripheral portion of the upper surface body 1 with the above-described rigid material like the power generation flooring material shown in FIG. 4, or as shown in FIG. Like the power generation floor material, the above-described flexible material may be integrally formed by projecting upward from the peripheral portion of the lower surface body 1. In these cases, the lower end of the bonding wall 3 formed integrally with the upper surface body 1 and the upper surface of the peripheral portion of the lower surface body 2, or the upper end of the bonding wall 3 formed integrally with the lower surface body 1 and the peripheral edge of the upper surface body 1. The pressure-sensitive power generation device 5 can be protected by securing the water-tightness of the storage portion 4 only by water-tightly bonding or welding the lower surface of the portion with an adhesive or the above-described welding means.

  In the power generation flooring shown in FIGS. 2 to 4, the lower end of the joining wall 3 is placed on and bonded or welded to the upper surface of the peripheral portion of the lower surface body 2, but the lower surface as in the power generation flooring shown in FIG. 6. Of course, the peripheral side surface of the body 2 may be water-tightly bonded or welded to the inner surface of the lower end of the joining wall 3.

  As shown in FIG. 18, the pressure-sensitive power generation device 5 disposed in the storage portion 4 formed by the upper surface body 1, the lower surface body 2, and the bonding wall 3 includes a rectangular plate-shaped cushioning material 5 a that is vertically stacked. 5b, a plurality of (9 in this embodiment) circular diaphragms 5c disposed on the lower cushioning material 5b, and barium titanate, zirconia, etc. joined to the lower surface of each circular diaphragm 5c. A disc-shaped piezoelectric element (not shown) made of a piezoelectric single crystal such as piezoelectric ceramics or lithium tantalate, and a shaft (not shown) that protrudes from the upper surface of the lower buffer material 5b and supports the central portion of each piezoelectric element from below. And a shaft (not shown) that protrudes from the lower surface of the upper cushioning material 5a and supports the periphery of each circular diaphragm 5c at a plurality of locations, and a tip of each shaft that projects from the lower surface of the upper cushioning material 5a. Stopper formed on Is obtained by a not shown).

  In the pressure-sensitive power generation device 5, when pressure (external force) is applied to either the upper or lower buffer material 5a or 5b, the central portion of each piezoelectric element is supported from below by the shaft of the lower buffer material 5b. Since the periphery of the circular vibration plate 5c is pressed from above by the shaft of the upper shock absorber 5a, the periphery of the circular vibration plate 3c and the piezoelectric element is relatively warped toward the lower shock absorber 5b. Electricity can be generated by warping deformation, and excessive deformation and breakage of the circular diaphragm 5c and the piezoelectric element at that time can be prevented by the stopper.

  Since this pressure-sensitive power generation device 5 is disclosed in detail in the above-mentioned patent document 1, further detailed description will be omitted.

  As shown by the phantom line in FIG. 2, the convex portion 6 provided on the lower surface of the lower surface body 2 applies walking pressure to the upper surface body 1 of the power generation floor material so that the upper surface body 1 and the joining wall 3 are moved downward. When moved, the convex portion forming portion of the lower surface body 2 and its peripheral portion are bent and deformed relatively upward while being supported by the floor base 7, and the pressure-sensitive power generation device 5 is sandwiched between the upper surface body 1 and the lower surface body 2. It plays the role of generating electricity by the pressure fluctuation.

The convex portion 6 may be formed of a rigid material, for example, a synthetic resin such as a hard vinyl chloride resin, a metal such as aluminum or stainless steel, a stone material, or the like. For example, it is desirable to form with a synthetic resin such as a soft vinyl chloride resin or a polyolefin resin, rubber, or a foam thereof. When the convex portion 6 is formed of the latter flexible or flexible material, it absorbs and relaxes the impact force from below and contributes to the protection of the pressure-sensitive power generation device 5, and also has unevenness and unevenness on the floor base 7. Even if there is, they can be absorbed and relaxed by the convex portion 6.
However, it is desirable that the material does not cause large volume shrinkage due to pressure, and it is desirable that the material is rich in repulsive force. From this viewpoint, a synthetic resin or rubber having a compressive strength of about 10 N / cm ² or more (preferably 1 kN / cm ² or more) is preferably used.

The convex portion 6 may be formed integrally with the lower surface body 2 with the same flexible material as the lower surface body 2 as in the power generation floor material shown in FIGS. The produced convex portion 6 may be bonded or welded to the lower surface of the lower surface body 2.
Further, the protruding dimension of the convex portion 6 may be determined in consideration of the amount of change necessary for power generation of the pressure-sensitive power generation device 6, the pressure-sensitive power generation device 6, the upper surface body 1, the gap size, and the like. It is desirable to set to about 10 mm.

As the shape of the convex portion 6, a shape such as a very thick square plate, a polygonal plate, a circular plate or the like is suitable, and the power generation floor shown in FIG. 1 has a shape of a very thick square plate. A convex portion 6 is formed.
The shape of the convex portion 6 is not limited to the above, and for example, it may be a concave / convex shape in which a plurality of small protrusions 6a are arranged vertically and horizontally like the convex portion 6 of the power generation flooring shown in FIG. Regarding the arrangement of the small protrusions 6a, when the convex part 6 is formed of a rigid material, it is only necessary to form one small protrusion 6a at each corner of the convex part 6. Further, as shown in FIG. 8, the peripheral side surface of the convex portion 6 may be an upwardly inclined surface, or the lower surface of the convex portion 6 may be a convex spherical surface as shown in FIG.

  For example, like the power generation flooring shown in FIG. 11, the convex portions 6 are respectively arranged below the pressure-sensitive power generation devices 5 and formed on the lower surface of the lower surface body 2 in the same number as the pressure-sensitive power generation devices 5. The projection area T from above may overlap the projection area S from above each pressure-sensitive power generation device 5, and as in the power generation flooring shown in FIG. 2, FIG. 7, FIG. One projection 6 is positioned below a group (four) of pressure-sensitive power generation devices 5, and a projection region T from above the projection 6 is a projection region from above the group of pressure-sensitive power generation devices 5. You may make it overlap with SG. In any case, it is desirable that the area of the projection region T from above the convex portion 6 is larger than the area of the projection region S or SG from above each pressure-sensitive power generation device 5 or the group of pressure-sensitive power generation devices 5. . The pressure-sensitive power generation device 5 may be divided into a plurality of groups (for example, two groups), and one convex portion 6 may be arranged below each group and provided on the lower surface of the lower surface body 2.

  When the relationship between the pressure-sensitive power generation device 5 and the convex portion 6 is as described above, when walking pressure is applied to the upper surface body 1, the convex portion forming portion and the peripheral portion of the lower surface body 2 are bent and deformed. The pressure-sensitive power generation device 5 is surely relatively pushed up and sandwiched between the lower surface body 2 and the upper surface body 1, and the pressure fluctuation is transmitted to all the pressure-sensitive power generation devices 5 without loss, thereby generating power. The power generation efficiency of the entire apparatus can be improved.

  The distance between the upper surface body 1 and the lower surface body 2 (in other words, the vertical dimension of the storage section 4) may theoretically be the same as the height dimension of the pressure-sensitive power generator 5, but if so, When a shocking pressure is applied to the material surface (upper surface body 1), the impact force is directly transmitted to the pressure-sensitive power generation device 5, which may cause a failure or breakage of the pressure-sensitive power generation device 5. Further, the pressure-sensitive power generation device 5 is always slightly compressed and deformed due to the weight of the flooring itself, the accuracy of the components, and the accuracy of assembly, and the power generation efficiency of the pressure-sensitive power generation device 5 may be deteriorated. Therefore, a gap (clearance) is provided between the pressure-sensitive power generation device 5 and the upper surface body 1 or the lower surface body 2 as described below so that an impact force is not directly applied to the pressure-sensitive power generation device 5 and pressure-sensitive power generation. It is desirable to prevent the device 5 from being slightly compressed and deformed at all times.

  That is, the pressure sensitive power generation device 5 is provided in direct contact with the upper surface of the lower surface body 2 as in the power generation floor material shown in FIG. 2, or the power generation floor material as shown in FIGS. The pressure power generation device 5 is provided in a state where it is indirectly in contact with the upper surface of the lower surface body 2 with the plate-like inclusions 8 interposed therebetween, and the upper portion of the pressure sensitive power generation device 5 and the lower surface of the upper surface body 1 are separated to form a clearance. The pressure sensitive power generation device 5 may be provided in direct contact with the lower surface of the upper surface body 1 as in the power generation floor material shown in FIG. 13, or the power generation floor material shown in FIG. As described above, the pressure-sensitive power generation device 5 is provided in a state in which the pressure-sensitive power generation device 5 is indirectly in contact with the lower surface of the upper surface body 1 with the plate-shaped inclusion 8 interposed therebetween, and the lower portion of the pressure-sensitive power generation device 5 and the upper surface of the lower surface body 2 are spaced apart. You may make it form (clearance).

The shocking pressure fluctuation (pressurization) is alleviated and the pressure-sensitive power generation device 5 can be protected more reliably. Further, when the power generation flooring is placed on the floor base 7 that is the laying surface, the lower surface body 2 is slightly bent and deformed relatively upward due to the weight of the power generation flooring, and is necessary for power generation of the pressure-sensitive power generation device 5. It is possible to eliminate the possibility of reducing the amount of deformation space, to prevent a decrease in power generation efficiency, and to absorb errors in molding accuracy and assembly accuracy of each member of the flooring.
It is appropriate to set the gap (clearance) to about 0.5 to 5 mm.

The plate-shaped inclusion 8 interposed between the pressure-sensitive power generation device 5 and the lower surface of the upper surface body 2 or the upper surface of the lower surface body 2 may be formed of a rigid material, such as a hard synthetic resin or metal. Alternatively, a flexible material such as a soft synthetic resin, rubber, or a foam thereof may be used. When the plate-like inclusion 8 formed of a rigid material is interposed, the pressure-sensitive power generation device 5 can be reliably protected by receiving an impact force, and the plate formed of a flexible material. When the inclusions 8 are interposed, the impact force can be absorbed and relaxed to similarly protect the pressure-sensitive power generation device 5.
The region in which the plate-shaped inclusion 8 is interposed completely overlaps with the projection region SG from above the group of pressure-sensitive power generators 5, and the area of the plate-shaped inclusion 8 is 1 of the area of the projection region SG. It is desirable to be 0 to 1.2 times. When the plate-shaped inclusion 8 and the pressure-sensitive power generation device 5 have such a relationship, the pressure-sensitive power generation device 5 can be protected more effectively.

The support column 9 is preferably formed of a material having rigidity, and the height of the support column 9 is the height of the pressure-sensitive power generation device 5, an appropriate amount of deformation to be applied to the pressure-sensitive power generation device 5, Although it is determined in consideration of a gap (clearance) between the pressure-sensitive power generation device 5 and the upper surface body 1 or the lower surface body 2, the height is preferably approximately 2 to 10 mm.

The place where the support pillars 9 are provided is not particularly limited. For example, the support pillars 9 are arranged on both sides of the group of pressure-sensitive power generators 5 as shown in FIG. As shown in FIG. 13, the support pillar 9 is disposed between the adjacent pressure-sensitive power generation devices 5 and suspended from the upper surface body 1 as in the power generation floor material shown in FIG. In addition, the support columns 9 are suspended from the upper surface body 1 so that the support columns 9 are positioned on both sides of the group of pressure-sensitive power generation devices 5 when the group of pressure-sensitive power generation devices 5 are pushed upward relatively. Like the power generation flooring shown in FIG. 15, support pillars 9 are arranged between both sides of the group of pressure-sensitive power generation devices 5 and the adjacent pressure-sensitive power generation devices 5 and are erected from the plate-like inclusions 8. 16, like the power generation flooring shown in FIG. 16, support pillars 9 are arranged on both sides of the group of pressure-sensitive power generation devices 5 and are erected from the lower surface body 2, or a plate Or vertically from the inclusions 8, as the power generation flooring illustrated in Figure 17, it may be erected from the plate-like inclusions 8 by placing the support post 9 on both sides of the sensitive pressure power device 5.
When the support pillar 9 is provided, it is better to erect or suspend the support pillar 9 from the plate-like inclusion 8 on which the pressure-sensitive power generation device 5 is placed, as in the power generation flooring shown in FIGS. As shown in FIGS. 12 to 14, it is desirable to assemble the power generating floor material more easily than to erect or suspend the support column 9 from the lower surface body 2 or the upper surface body 1.

Since the power generation flooring having such a structure surrounds the upper and lower sides of the pressure-sensitive power generation device 5 with the rigid upper surface body 1 and the plate-like inclusions 8, even when an impact force is applied to the upper surface body 1. In addition, even when pebbles or the like on the laying surface push up the flexible lower surface body 2 from below, the pressure-sensitive power generation device 5 is protected from damage by the rigid upper surface body 1 and the plate-shaped inclusion 8. be able to. Moreover, since the small convex part 6 which has rigidity can be provided in multiple numbers on the lower surface of the lower surface body 2, the unevenness | corrugation of a laying surface can be absorbed easily.

1 to 17 described above, when walking pressure is applied to the upper surface body 1 from above, the entire floor material tends to move downward, but the downwardly projecting portion of the lower surface body 2 Since 6 is supported from below by a floor base 7 which is a laying surface, the lower surface body 2 having flexibility has its convex portion forming portion and its peripheral portion bent upward and deformed and pushed upward relatively. Will be. Therefore, the pressure-sensitive power generation device 5 arranged in the storage portion 4 between the upper surface body 1 and the lower surface body 2 is pinched by the convex portion forming portion of the lower surface body 2 and its peripheral portion and the upper surface body 1, and walking pressure is increased. Is effectively transmitted to the pressure-sensitive power generation device, so that the pressure-sensitive power generation device 5 can efficiently generate power by the pressure fluctuation. And when the convex part formation part of the lower surface body 2 and its peripheral part deform | transform flexibly as mentioned above, since the force (repulsive force) which returns to the original shape generate | occur | produces in the flexible lower surface body, At the same time as the walking pressure is removed, the lower surface body 2 is restored to its original shape, and the pressure-sensitive power generation device 5 is depressurized.

This temporary support column supports the flooring with a force that balances with the weight of the power generation flooring. If a pressure higher than its own weight is applied to the power generation flooring, it is added without supporting the power generation flooring. The generated pressure is transmitted to the pressure-sensitive power generation device 5 through the convex portion 6.

  The laying surface 7 on which the power generation flooring material is laid may be a flat floor base made of concrete, wood, or the like, or may be a gravel, a floor with some unevenness or unevenness. However, a floor base formed of a very soft material (for example, a cushion floor having a very high cushioning property) is not preferable.

  Next, based on FIGS. 19-22, embodiment of the electric power generation floor material which made it possible to guide | invade a pedestrian safely also in a dark place by making a light emitting element light-emit with the generated electric power is demonstrated.

The lead wires 15a and 15b may not be penetrated through the joining wall 3, but may be cut out at a part of the joining wall 3 and drawn out to the corner portion of the power generation flooring P. It is desirable to seal the lacked part with a sealing material after watertight.

  Note that a decorative or anti-slip covering sheet 6 may be stacked on the surface of the upper surface body 1 to enhance the design or provide an anti-slip function.

  The power generation flooring connector shown in FIG. 21 is arranged in a straight line with the above-mentioned power generation flooring P adjacent to each other, and the connecting edge members 11 are arranged on both left and right edges of the power generation flooring P adjacent to each other. Each of the power generation flooring materials P is connected by the connecting edge material 11 so as to be detachable by shifting the position by the pitch, and is positioned at the front edge and the rear end of the power generation flooring material P located at the front end. A non-connecting edge member 110 is provided at the rear end edge of the power generation floor material P, and left and right side edges of the power generation floor material P positioned at the front half and the rear end of the power generation floor material P positioned at the front end.

The number of power generation floor materials P to be connected may be two or more, and the connection form is a linear connection form as shown in FIG. 21, an L-shaped connection form, or a cross-shaped connection form. However, other desired connection forms may be used.

  As shown in FIG. 22, the connecting edge member 11 is formed by integrally providing an outer edge portion 11b having a cross section of a substantially right triangle on the outer side of the horizontal overlapping edge 11a, and the upper surface and the outer edge of the overlapping edge 11a. A plurality of shallow grooves 11c for providing anti-slip properties are formed on the gentle slope of the portion 11b, and a plurality of grooves 11d for stealing meat are formed on the bottom surface of the outer edge portion 11b. On the lower surface of the edge 11a, the other planar material 17b having an engagement hook or an engagement loop of the hook-and-loop fastener 17 is attached.

  The connecting edge member 11 has substantially the same length as the lengths of the left and right side edges of the power generation floor material P. The edge material 11 is connected to the power generation floor material P as shown in FIG. As shown in FIG. 22, the overlapping edge 11 a of the edge member 11 is overlapped with the attachment portion 12 on the side edge of the power generation flooring P, and the one side of the hook-and-loop fastener 17.

The bottom surface of the portion 11b and the bottom surface of the convex portion 6 of the lower surface body 2 are flush with each other.

  The material of the connecting rim material 11 is not particularly limited, and any rim material made of various synthetic resins, rubber, metal, wood, etc. can be used. An edge material 8 formed of a soft synthetic resin such as an olefin resin is preferably used. When the power generation floor material P is connected with the edge material 11 made of such a soft synthetic resin, even if there is unevenness on the installation surface of the power generation floor material connection body, the edge material 11 made of the soft synthetic resin is deformed, There is an advantage that the power generation flooring connected body can be installed while following the unevenness and bending at the connecting part of the power generation flooring. The rubber edge member 11 is also preferably used because it has the same advantages.

  The non-connecting edge members 110 and 111 have the same material and the same cross-sectional shape as the connecting edge member 11, and like the connecting edge member 11, the hook-and-loop fastener 17 is provided on the lower surface of the overlapping edge. The other planar material 17b having the engagement hook or the engagement loop is affixed.

Therefore, when this power generation flooring assembly is installed at night or in a dark place, the pedestrian's guidance effect and visibility are remarkably improved by the light emission / lighting of the light emitting elements 10a of the belt-like light emitting portions 10 of each power generation flooring P. Have an advantage

  The light emitting elements 10a of the band-like light emitting portions 10 of the respective power generation floor materials P need not be controlled so that all of the light emitting elements 10a emit and light all at once. It may be controlled to emit light / light up. For example, when the size of the power generation flooring P is large and the belt-like light emitting unit 10 is considerably long, the light emitting element 10a located ahead of the pressure sensitive power generation device 5 that senses the walking pressure is simultaneously lit and lit. You may control.
