[Embodiment 1]
First, the first embodiment will be described. In this form, the exercise device is configured as a grip strength enhancing device.

(overall structure)
1 is a schematic overall perspective view of the grip-strengthening device according to Embodiment 1, FIG. 2 is an enlarged longitudinal sectional view of region A in FIG. 1, FIG. 3 is a longitudinal sectional view of a power generation module, and FIG. 4 is a modification of FIG. It is a longitudinal cross-sectional view of the power generation module in a state. As shown in FIG. 1, the grip strength enhancing device 1 includes a spring 11, a pair of grip bodies 12, a power generation module 13, and a lamp 14.

(Overall structure-spring)
The spring 11 is for absorbing energy using elasticity. The central portion of the spring 11 is formed in a spiral shape, and both end portions of the spring 11 are formed in a linear shape. Although the specific material used for this spring 11 is arbitrary, for example, a metal material such as steel is used.

(Overall structure-gripping body)
The pair of gripping bodies 12 are gripping means for the user to grip the grip strength enhancing device 1. The pair of gripping bodies 12 are formed of a rod-like hollow body or solid body, and are fixed to the linear ends of the spring 11 in a state of being separated from each other. Although the specific material used for this pair of holding body 12 is arbitrary, resin materials, such as metal materials, such as steel and aluminum, and plastic materials, etc. are used, for example.

  As shown in FIG. 2, a concave portion is formed on the outer side of the grip body 12, and a pressure receiving portion 12a and a support portion 12b are provided in the concave portion. The support portion 12b is a support means for supporting the power generation module 13, and is fixed to the concave portion of the grip body 12 by fitting or bonding. The support portion 12b includes a recess 120b. The pressure receiving portion 12a is pressure receiving means for receiving a force applied to the pair of grip bodies 12 when the user grips the pair of grip bodies 12, and is disposed at a position facing the support portion 12b. It is connected to the part 12b by an arbitrary method. The pressure receiving portion 12a protrudes toward the support portion 12b and includes a convex portion 120a that is slidably inserted into the concave portion 120b.

  The power generation module 13 is disposed between the convex portion 120a and the concave portion 120b. A predetermined clearance is provided between the support portion 12b and the pressure receiving portion 12a in addition to the thickness at which the power generation module 13 is disposed. The predetermined clearance can be set arbitrarily. For example, when the pressure receiving portion 12a receives a force corresponding to the strength of the spring 11 by the user holding the pair of grip bodies 12, the predetermined clearance is set. Is set so that the convex portion 120a presses the power generation module 13. In addition, although the connection method of the support part 12b and the pressure receiving part 12a is arbitrary, for example, an elastic member (not shown) such as a spring having a biasing force in the extension direction between the support part 12b and the pressure receiving part 12a. ) And both ends of the elastic member are fixed to the support portion 12b and the pressure receiving portion 12a, respectively, so that the pressure receiving portion 12a does not fall off from the support portion 12b and the pressure receiving portion 12a is pressed from the outside. In the absence, the pressure receiving portion 12a may be held in the state where the clearance is maintained with respect to the support portion 12b.

(Overall configuration-power generation module)
2 to 4, the power generation module 13 includes a piezoelectric element 13a, a peripheral spacer 13b, and a central spacer 13c.

  The piezoelectric element 13a is an element that generates electricity by being deformed by pressure. For example, the piezoelectric element 13a is made of piezoelectric ceramics such as barium titanate or zirconia, or a piezoelectric single crystal such as lithium tantalate (LiTaO3). The piezoelectric element 13a is formed in a thin plate shape, and is formed between one side surface of the piezoelectric element 13a and the concave portion 120b so that the piezoelectric element 13a is curved in a direction in which the convex portion 120a protrudes toward the concave portion 120b. The side surface and the other side surface of the piezoelectric element 13a and the side surface of the convex portion 120a are disposed at positions facing each other. Although not shown, the piezoelectric element 13a has a plus terminal on one surface of the piezoelectric element 13a, a minus terminal on the other surface of the piezoelectric element 13a, and a plus lead wire connected to the plus terminal. The negative lead wire connected to the negative terminal is drawn out and connected to the lamp 14 through a control circuit (not shown), whereby electric power is supplied to the lamp 14. However, various electric elements such as a known bridge circuit may be disposed between the piezoelectric element 13 a and the lamp 14. Alternatively, as the piezoelectric element 13a or in place of the piezoelectric element 13a, any material that can generate power by external force (including a force that causes distortion, bending, or compression) can be used. Ionic polymer metal composite material (IPMC: Ionic Polymer-Metal Composite) in which metal (gold) is plated on both surfaces of a molecular film (gel), ion conductive polymer gel film (ICPF: Ionic Conducting Polymer Gel Film), Alternatively, artificial muscles using these IPMC and ICPF can be used. This point is the same in other embodiments described later. In addition, these piezoelectric elements 13a and arbitrary materials capable of power generation are collectively referred to as “power generation elements” as necessary.

  The peripheral spacer 13b and the central spacer 13c form a space for easily deforming the piezoelectric element 13a between the convex part 120a and the concave part 120b and the piezoelectric element 13a. The central spacer 13c is a columnar body disposed between the piezoelectric element 13a and the convex portion 120a and in the vicinity of the center of the side surface of the piezoelectric element 13a. On the other hand, the central spacer 13c is a plurality of columnar bodies or one annular body disposed between the piezoelectric element 13a and the recess 120b and in the vicinity of the peripheral edge of the side surface of the piezoelectric element 13a. In this case, in order to obtain structural stability, the peripheral spacers 13b are arranged at three locations corresponding to the vertices of the equilateral triangle with the center of the plane of the piezoelectric element 13a as the centroid. Or may be arranged at three or more locations. The central spacer 13c and the peripheral spacer 13b are fixed to the piezoelectric element 13a with an adhesive or the like, for example. Specific materials used for the central spacer 13c and the peripheral spacer 13b are arbitrary, but those having higher strength than the piezoelectric element 13a are preferable. For example, metal materials such as steel, stainless steel, and aluminum are used.

  When the peripheral spacer 13b and the central spacer 13c are arranged in this way, when the pressure receiving portion 12a is pressed from the outside, the center of the side surface of the piezoelectric element 13a is pressed through the central spacer 13c, and as shown in FIG. 13a is deformed.

(Overall structure-lamp)
In FIG. 1, a lamp 14 is a light emitting means that emits light using a current generated by deformation of the piezoelectric element 13a. The ramp 14 is embedded in the lower surface of the grip body 12 and is fixed to the grip body 12 by a fitting structure or the like. The lamp 14 is electrically connected to the power generation module 13 via a control circuit (not shown). Accordingly, when the user grips the pair of grip bodies 12 with a predetermined force, when the pressure receiving portion 12a receives the force, the piezoelectric element 13a of the power generation module 13 is deformed to generate a current, and the generated current is used. Then, the lamp 14 is turned on or blinks. The lighting or blinking method of the lamp 14 is arbitrary. For example, the lamp 14 lights or blinks when the deformation of the piezoelectric element 13a is equal to or greater than a predetermined value, and the deformation of the piezoelectric element 13a is smaller than the predetermined value. In some cases, there is a method of not lighting or flashing. Thereby, the grip strength enhancing device 1 can present to the user whether or not the grip strength enhancing device 1 is appropriately used. In addition, although the specific kind used for this lamp | ramp 14 is arbitrary, a small lamp, a fluorescent lamp, an LED lamp etc. correspond, for example.

  In addition, any structure can be adopted as a fixing structure of the power generation module 13 in the grip strength enhancing device 1. (A)-(d) of FIG. 5 is a figure which simplifies and shows the area | region A of FIG. 2 which concerns on a modification. As shown to (a)-(d) of FIG. 5, in this modification, the holding body 12 is provided with two or more support parts 12b and pressure receiving parts 12a. Moreover, the holding body 12 includes a plurality of power generation modules 13 between the support portion 12b and the pressure receiving portion 12a. According to this structure, the lateral displacement between the support portion 12b and the pressure receiving portion 12a can be prevented, so that the pressure receiving portion 12a can reliably press the piezoelectric element 13a of the power generation module 13, and the power generation module 13 The amount of power generation can be improved.

  FIG. 6 is a view showing an example of an exercise apparatus according to a modified example, FIG. 6 (a) is a view used for a cane 101, and FIG. 6 (b) is used for a baseball bat 102. FIG. 6C is a diagram used for the kendo armor body 103.

  As shown in FIG. 6A, the cane 101 includes a cane body 111, a grip body 112, a power generation module 113, and a lamp 114. The cane body 111 transmits the weight of the user to the ground. The grip body 112 is a grip means for the user to grip the cane 101, and is configured to include a support portion 12 b and a pressure receiving portion 12 a on the upper surface of the grip body 112. The power generation module 113 is disposed between the support portion 12b and the pressure receiving portion 12a. The lamp 114 is embedded in the side surface of the cane body 111. According to this structure, when the user puts weight on the cane 101 and the pressure receiving portion 12a receives this weight, the piezoelectric element 13a of the power generation module 113 is deformed to generate a current. Thereby, since the lamp 114 is turned on or blinks, for example, it is possible to alert the surroundings when walking at night.

  As shown in FIG. 6B, the baseball bat 102 includes a grip 121, a bat main body 122, a power generation module 123, and a lamp 124. The grip 121 is for gripping the baseball bat 102. The bat main body 122 is a contact means that comes into contact with the ball, and includes a support portion 12b and a pressure receiving portion 12a on the side surface of the bat main body. The power generation module 123 is disposed between the support portion 12b and the pressure receiving portion 12a. The lamp 114 is embedded in the upper surface of the bat body 122. According to this structure, when the user hits the ball at a predetermined portion of the bat main body 122 and the pressure receiving portion 12a receives the impact force of the ball, the piezoelectric element 13a of the power generation module 123 is deformed to generate a current. Thereby, since the lamp 123 is lit or blinking, it can be determined whether or not the lamp 123 is lit or blinking to determine whether or not the ball can be hit at a predetermined position. For example, when a plurality of power generation modules 123 and a plurality of lamps 123 having different colors are embedded in a plurality of different locations of the bat main body 122, and the different power generation modules 123 are pressed, the lamps 123 having different colors are turned on or If it blinks, the location where the ball could be hit can be determined more accurately.

  As shown in FIG. 6C, the kendo armor body 103 includes a body body 131, a power generation module 132, and a lamp 133. The trunk body 131 is a contact means that abuts against the bamboo sword.

The power generation module 132 is disposed between the support portion 12b and the pressure receiving portion 12a. A plurality of lamps 133 are embedded in the outer side surface of the trunk body 131. According to this structure, when the user applies a bamboo sword to a predetermined portion of the trunk body 131 and the pressure receiving portion 12a receives the impact force of the bamboo sword, the piezoelectric element 13a of the power generation module 132 is deformed to generate a current. . Thereby, since the lamp 133 is lit or blinking, it can be determined whether or not the lamp 123 is lit or blinking to determine whether or not the opponent's bamboo sword hits a predetermined portion of the trunk body 131. For example, when a plurality of power generation modules 132 and a plurality of lamps 133 having different colors are respectively embedded in a plurality of different locations of the trunk body 131 and the different power generation module trunk bodies 131 are pressed, the lamps 133 having different colors are displayed. If it lights up or blinks, the location where the opponent's bamboo sword hit can be determined more accurately.

(Effect of Embodiment 1)

And an electric wire connecting the commercial power supply are not necessary. Therefore, even when power is supplied to the grip strength enhancing device 1, the portability of the grip strength enhancing device 1 can be improved. In addition, when the grip strength enhancing device 1 is used, a current is generated by pressing the piezoelectric element 13a of the power generation module 13 with the pressure receiving portion 12a. Therefore, it is possible to generate power regardless of the usage conditions such as the place of use. The versatility of the grip-strengthening device 1 can be enhanced. Moreover, since the electric power generation module 13 can be arrange | positioned between the support part 12b and the pressure receiving part 12a, or can be arrange | positioned in the vicinity of the pressure receiving part 12a, it can apply to various exercise equipments and has high versatility. Furthermore, since the power generation module 13 uses the piezoelectric element 13a, the material cost is low, and the manufacturing cost can be reduced.

  Further, since the pressure receiving portion 12a is a part of the grip body 12, the piezoelectric element 13a can be naturally pressed using the user's weight, gripping force, etc., so that the user is not conscious of power generation, Power generation using the user's kinetic energy becomes possible.

  In addition, since the pressure receiving portion 12a is a part of an object that comes into contact with an external object such as the bat main body of the baseball bat 102, the piezoelectric element 13a can be pressed by the force of the external object. Power generation using the kinetic energy of the object is possible.

  In addition, since the power generation module 13 is disposed between the convex portion 120a and the concave portion 120b, the piezoelectric element 13a can be effectively pressed, and lateral shift between the support portion 12b and the pressure receiving portion 12a can be prevented. It is possible to prevent power generation efficiency.
