JP, 2015-168959, A

In the batteryless remote control device described in Patent Document 1, since the movement of the button is not interlocked, unnecessary pressing force is not generated when the button is pressed, which is convenient for the user.
Such a batteryless remote control device is also required to reduce the manufacturing cost, and looking at the embodiment of this device from this point of view, it is necessary to convert the button pressing operation into the rotation operation, thus increasing the number of parts. As a result, it can not deny the increase of the manufacturing cost.
In the example of the modification shown by FIG. 8 of patent document 1, it is made to oppose the cam follower part which made the lower end of the button be a cam part, and was made to project from a link. Thereby, the pressing movement of the button is directly converted to the parallel movement of the link. However, since the height is required for the inclined surface of the cam follower portion facing the cam portion, in a device having a structure in which the cam follower portion protrudes from the link, in order to secure the height, an increase in overall thickness is avoided. I can not.

Means to solve the problem

One object of the present invention is to solve the above problems. That is, the first aspect of the present invention is defined as follows.
With the case,
A plurality of buttons movably attached to the case;
A power generation element that generates power using the power of the button operation;
A button operation detection unit that detects an operation of the button;
A transmission circuit that transmits a predetermined signal to the outside based on the detection result of the button operation detection unit, wherein the transmission power is supplied from the power generation element;
A power generation element operation unit that operates on the power generation element in conjunction with the operation of each button to cause power generation, and a main body, a first connecting portion that connects the main body and each button, and the main body And a second connecting portion connecting the power generating element and
When at least one of the buttons is operated, the main body moves in the case through the first connecting portion, and when the operation of each button is released, the main body returns to the position before the operation. ,
The second connection part acts on the power generation element to generate power as the main body moves.
In the batteryless remote control device,
The said main-body part is equipped with the through-hole in the part facing the said button, The battery-less remote control apparatus with which the said 1st connection part is couple | bonded with the surrounding surface of this through-hole.

According to the batteryless remote control device of the first aspect defined as described above, the first connecting portion is connected to the circumferential surface of the through hole of the main body portion. When the first connecting portion is constituted by the cam portion on the button side and the cam follower portion on the main body side, the thickness of the main body portion is set as the height of the slope of the cam follower portion by utilizing the peripheral surface of the through hole as a cam follower portion. Since it can be used, the cam follower part which protrudes from the main body part becomes unnecessary.
The first connector converts the movement of the button (e.g., movement in the vertical direction with respect to the case) into the lateral movement of the main body (e.g., movement along the case). A link mechanism can be employed in addition to the cam mechanism described above. Also in the link mechanism, since the links and joints that constitute the link mechanism can be disposed in the through holes, there is no need to make the case thick.

In the through hole, it is preferable that the circumferential surface on the downstream side in the moving direction be orthogonal to the moving direction of the main body (second aspect). This facilitates connection of the first connection part.
Furthermore, the main body portion is formed in a ladder shape including a pair of longitudinal members and a plurality of lateral members suspended on the longitudinal members, the through hole is rectangular, and the first connecting portion is formed on the side surface of the lateral members. Being preferred (third aspect). The ladder shape can reduce the weight of the main body as much as possible. In addition, it is possible to make the cross bar part a rod-like roller by making the cross bar part double-supported with respect to the cross bar part. A rod-like roller can also be used as a cam follower.

The batteryless remote control device of the fourth aspect of the present invention is defined as follows.
In the batteryless remote control device defined in any one of the first to third aspects,
The first connection portion includes a first cam portion formed on the button, and a first cam follower portion formed on a circumferential surface of the through hole of the main body portion so as to face the first cam portion. The operation of the button causes the first cam portion to press the first cam follower portion to move the main body portion.
In this aspect, it is defined that the first connecting portion is a cam mechanism. The cam mechanism has a smaller number of parts than the link mechanism, and meets the demand for cost reduction.
Here, the first cam portion of each button is an inclined surface in the same direction. The same direction as referred to herein means the direction in which the power generation element is caused to generate power, and does not necessarily point to the same direction physically. For example, as exemplified in Patent Document 1, in the structure in which the first link member and the second link member move in the opposite direction from the gear, the slope of the cam portion facing the first link member And the second link member are physically opposite to that of the cam portion facing the second link member, but can be defined as the same direction in terms of the direction of generating power from the power generation element. These link members correspond to the main body of the present invention.
An inclined surface is also formed on the peripheral surface of the through hole with respect to the inclined surface of the first cam portion of the button. That is, the inclined surface as a 1st cam follower part is formed in the surrounding surface of the same direction in each through-hole (5th aspect). The traverse part may be a rod-like roller (sixth aspect). In the case of a rod-shaped roller, the inclined surface is unnecessary.
A rod-shaped roller may be employed as the first cam portion of the button. In this case, an inclined surface is formed on the same side surface in each cross bar.

The fifth aspect of the present invention is defined as follows. That is, in the batteryless remote control device defined in the fourth aspect, the inclined surface formed on the same side surface of the circumferential surface of each through hole is the cam follower portion.
By adopting such a configuration, the structure of the first connecting portion is simplified.

The sixth aspect of the invention is defined as follows. That is, in the battery-less remote control device as defined in the third aspect, the first connection portion includes a first cam portion formed on the button and the cross bar portion as a first cam follower portion, and the cross bar portion is The rod-shaped roller, wherein the first cam portion presses the cross bar of the rod-shaped roller by the operation of the button to move the main body portion.
According to the battery-less remote control device of the sixth aspect defined in this manner, the drive of the cam mechanism becomes smooth and the operability is improved by employing the rod-like roller.

The seventh aspect of the present invention is defined as follows. That is, in the batteryless remote control device as defined in any one of the first to sixth aspects, the button detection unit is a push button switch, and is disposed in the through hole of the main unit opposite to the button. A detection unit that sends a signal to the transmission circuit when the button is pressed, and a first elastic member that biases the button in a direction opposite to the pressing direction.
According to the battery-less remote control device of the seventh aspect defined as described above, the button detection unit includes the first elastic member. The first elastic member elastically supports the button in a non-depressed state, and after the button is depressed, the button is pushed back to its original position when the depression is released. A compression coil spring can be used as such an elastic member. The compression coil spring has conventionally been disposed separately from a switch for detecting depression of a button. By adopting a push-button switch, the number of parts is reduced. Of course, in order to stabilize the button operation, a compression coil spring may be employed separately from the push button switch, that is, additionally. In addition, an elastic member having a spring elasticity that exhibits the same function, such as rubber, an elastomer, a tension coil spring, a spring plate or the like can be adopted.

In this aspect, it is defined that the push button switch is disposed in the through hole of the main body. This is a structure obtained by providing a through hole in the main body, which allows the device to be miniaturized.
Instead of the push button switch, a general-purpose contact switch or non-contact switch can be employed as a button operation detection unit. In these cases, a compression coil spring is interposed between the button and the case. Of course, also when a push button switch is adopted, a compression coil spring can be separately interposed.
A general-purpose circuit can be adopted as the transmission circuit. In the toilet and the like, the transmission circuit plays the role of a radio transmitter. The signal transmitted from the transmission circuit may be transmitted by wire to the device to be controlled.

The eighth aspect of the present invention is defined as follows. That is, in the batteryless remote control device according to the seventh aspect, a second elastic member is provided between the main body and the case, and the second elastic member moves the main body moved by the operation of the button. Bias toward the position before movement.
According to the batteryless remote control device defined in the eighth aspect defined as described above, when the pressing of the button is released, the main body itself is returned to the original position by the second elastic member. At this time, the button is also pushed back through the first connecting portion as the main body moves. Here, in conjunction with the return action of the button by the push button switch, the action of making the button neutral is reliably performed.
The compression coil spring can be adopted as the second elastic member. In addition, an elastic member having a spring elasticity that exhibits the same function, such as rubber, an elastomer, a tension coil spring, a spring plate or the like can be adopted.

The ninth aspect of the present invention is defined as follows. That is, in the batteryless remote control device as defined in the third aspect, the second cam follower portion formed in the warp of the main body portion and the power generating element and opposed to the second cam portion And the second connection portion is formed.
According to the batteryless remote control device defined in the ninth aspect defined in this manner, the cam mechanism is adopted in the second connecting portion, so that the structure becomes simple. Further, by providing the second cam portion in the warp, the degree of freedom in the arrangement of the power generation element is increased.

The tenth aspect of the present invention is defined as follows. That is, in the batteryless remote control device as defined in the third aspect, the pair of traverse members in the main body constitutes a first cam follower, and the button has an inclined surface formed to face the pair of traverse members. And
The push button switch type button detection unit is disposed between the pair of crossbars.
According to the batteryless remote control device defined in the tenth aspect defined in this manner, since the pair of cross bar portions are cam follower portions and the pair of cam portions opposed thereto are provided on the button, the contact between the button and the cross bar portion The point increases. This stabilizes the button pressing operation. That is, a cam mechanism consisting of a plurality of cam-cam followers can be arranged in the projection plane of the button in the pressing direction of the button. Therefore, even if the button is pressed at a position deviated from the center, the pressing operation is reliably transmitted to the main body, and the movement of the main body is stabilized.
In this aspect, the push butane switch is disposed between the rungs. Since the push butane switch is disposed between the pair of cams, the support of the button is more stable.

FIG. 7 is a plan view showing a main body of another embodiment. FIG. 8 is a schematic view showing a button and a switch attached to the main body shown in FIG.

FIG. 1 is an exploded perspective view of a battery-less remote control device (hereinafter sometimes abbreviated as “device”) 1 according to an embodiment of the present invention.
The device 1 includes a case 10, a button 20 (see FIG. 3), and a power generation element operation unit 100.
The case 10 is divided into an upper cover 11 and a lower cover 30, and a button hole 12 is opened in the upper cover 11. As shown in FIGS. 2 and 3, the button 20 is inserted into the button hole 12 so as to be movable in the axial direction, that is, in the thickness direction of the upper cover 11. A tubular reinforcing portion 14 is formed around the button hole 12.

The button 20 includes a pressed portion 21, a switch pressing portion 25 and a cam portion 26. The pressed portion 21 has, for example, a disk shape, and characters and symbols are printed on the surface of the pressed portion 21 so that the action of the button can be grasped.
From the peripheral edge of the pressed portion 21, the edged portion 23 hangs down to the side opposite to the design surface (the lower side in FIG. 2). The rim portion 23 has a cylindrical shape, and the outer diameter thereof is substantially equal to the inner diameter of the reinforcing portion 14 of the upper lid portion 11, and both are in a sliding state. The lower end of the rim 23 is bent outward to form a flange 24. The flange 24 abuts on the lower end of the reinforcing portion 14 so that the button 20 does not come off the upper cover 11.

A bar-like switch pressing portion 25 is provided in a substantially central position on the back surface (a side opposite to the design surface) of the pressed portion 21. The switch pressing portion 25 faces the push button switch (which may be simply referred to as a "switch" hereinafter) 200, and presses the switch 200 to turn on when the button 20 is pressed. The shape of the switch pressing portion 25 can be arbitrarily changed in design so that the switch 200 can be pressed.
A pair of cam portions 26 are provided on the back surface of the pressed portion 21 so as to sandwich the switch pressing portion 25. The cam portion 26 is plate-shaped. Inclined surfaces are formed at both corners of the free end of the plate (lower end in FIG. 3). This inclined surface is the first cam portion 27.
In this example, the same plate-like cam portion 26 is provided at the target position from the center on the back surface of the pressed portion 21 and the first cam portion 27 is formed at both corners of the free end of each plate. As a result, the four first cam portions 27 are arranged at positions radially from the center of the pressed portion 21 and in point symmetry in plan view. Therefore, when a portion other than the center of the pressed portion 21 is pressed, the inclined portion is supported by the lower cam mechanism. Therefore, the pressed portion 21 maintains its horizontal state with almost no sagging, and presses the cross bar portion 130 stably.
Of course, the structure of the cam portion 26 can be arbitrarily designed as long as the cross cam portion (that is, the first cam follower portion) can be pressed by the first cam portion 27.
Although a flat inclined surface is employed as the first cam portion 27 in this example, it may be a curved surface. When a curved surface is adopted, the feeling of pressure on the button can be changed. The forming direction of the inclined surface is the same direction, and is directed to the moving direction of the main body portion 101. A rod-shaped roller can be employed as the first cam portion 27. That is, rod-like rollers are suspended at both corners of the free end of the pair of cam portions 26. In this case, the cross timber portion 130 is an inclined surface. The sloped surface of the cross section is opposite to the moving direction of the main body 101. That is, it is a direction facing the first cam portion of the inclined surface shown.

As shown in FIG. 6, the main body portion 101 has a ladder shape. That is, the plurality of cross-leaves 130 are suspended on the pair of warps 110. In this example, the cross bar portion 130 is a rod-shaped roller facing the first cam portion 27 of the button 20. As shown in FIG. 6, in addition to the rod-like roller, a reinforcing beam 133 is installed as a second cross bar.
In this example, the cross bar 130 is a rod-like roller and this is the first cam follower facing the first cam 27. However, the cross bar 130 is a non-rotating member, that is, a bar. The side surface may be an inclined surface. This inclined surface is the first cam follower portion.

The longitudinal timber portion 110 of the main body portion 101 is a long plate-like member, and a slide portion 111 and a guided portion 113 are formed on the lower surface thereof. The slide portion 111 is in contact with the lower lid portion 30 and can slide relative thereto. The slide portion 111 is preferably formed at a position opposed to the button 20, whereby the barb portion 110 is not deformed even when the button 20 is pressed and a downward force is applied to the cross bar portion 130.
When the lower surface of the barbed portion 110 is entirely brought into contact with the lower lid portion 13, the contact resistance increases, so the contact area of the slide portion 111 is limited. In other words, it is preferable that the lower surface of the vertical plate portion 110 other than the slide portion 111 be separated from the lower lid portion 30.
In this example, a plate-like guided portion 113 is provided on a part of the lower surface separated. A guide rail 31 is formed in the lower cover 30 so as to sandwich the guided portion 113. When the button 20 is pressed and the pressing force is transmitted from the first cam portion 27 to the flute portion 130, the flute portion 110, that is, the main body portion 101 moves along the guide rails 31. A compression coil spring 115 is provided between the lower cover 30 and the free end of the cross bar 110. The compression coil spring 115 biases the barbed portion 110, which has been moved according to the depression of the button, in the direction opposite to the movement. By this, when the pressing operation of the button is released, the barbed portion 110 is returned to the original position. In this return operation, the cross beam portion 130 presses the first cam portion 27 and lifts the button 20.

A second cam portion 120 is formed on the outer side surface of one of the warps 110.
The second cam portion 120 faces the movable portion of the power generation element 300. That is, when the second cam portion 120 moves along with the movement of the vertical stem portion 110, the movable portion (second cam follower portion) of the power generating element 300 disposed to face the second cam portion is operated and the power generating element 300 generates power. .
In this example, an electromagnetic induction type was used as the power generation element 300. A piezoelectric element type power generation element can also be used. The power generation element 300 is disposed to face the outer side surface of the vertical bar portion 110, but the arrangement position of the power generation element 300 is not particularly limited, and the inner side surface and the upper surface of the vertical bar portion 110, Alternatively, it can be provided to face the end surface (surface on the side of the compression coil spring 115). Furthermore, it is also possible to provide a cross cam portion 130 with a second cam portion. In these cases, it is needless to say that the second cam portion is provided to face the power generation element 300.

The switch 200 is disposed between the pair of cross bar portions 130 with which the first cam portion 27 of the button 20 abuts. This switch is a push button type and incorporates a compression coil spring, and when the button 20 is depressed, it is biased in the opposite direction. Thereby, the button 20 is returned to the original position in cooperation with the compression coil spring 115 provided on the end face of the cross section 110 of the main body portion 101.
The switch 200 is turned on when the button is pressed. That is, the operation of the button 20 is detected. The on state is reflected to a transmission circuit (not shown), and a signal corresponding to the on state is transmitted to the outside. At the same time as the switch 200 is turned on, the power generation element 300 is also turned on. The power generated by the power generation element 300 is supplied to a transmission circuit, whereby a signal corresponding to the on state of the switch 200 is transmitted to the outside. A button operation detection, a transmission circuit, and a system for supplying power from the power generation element to the transmission circuit can be a versatile one.
The button 20 is supported by the push button switch.

In this example, since the switch 200 is disposed between the cross beam portions 110, the entire device can be made compact in the width direction of the case. Further, since the side surface of the cross bar portion 110 is used as the first follower portion, it is not necessary to project the first follower portion upward, and the case can be made compact in the thickness direction of the case.
Looking at the above example from the standpoint of equipment compactness, the following is extended. In compacting in the thickness direction of the case, a through hole is formed in the main body (link mechanism) of the power generating element operation unit that causes the power generating element to generate power in conjunction with the operation of the button. It is understood that the surface may be used as the first cam follower. Further, by disposing the switch in the through hole, it is possible to achieve compactness in the width direction of the case.

7 and 8 show an example of the main body 400 of another power generation element operating unit. In the main body 400, a through hole 401 is formed in a plate-like member. The shape of the through hole 401 is arbitrary, but the surface on the downstream side in the moving direction of the main body 400 in the circumferential surface thereof is a slope, that is, the first cam follower surface 403.
With respect to the main body 400, the cam portion 426 is disposed at the central portion of the button 420, and the lower surface of the cam portion 426 is an inclined surface (first cam portion 427). Reference numeral 430 is a push button switch.
In the above, the circumferential surface of the through hole may not be continuous. In other words, a notch may be provided from the side surface of the main body to be a through hole. In this case, in order to secure the rigidity of the main body, the material, thickness, size of the notch, and the like are appropriately designed according to the application of the device.
The main body portion is not limited to a linear plate, and may be bent in two dimensions and three dimensions. Further, as shown in Patent Document 1, a plurality of main body portions can be connected by gears.

The batteryless remote control device 1 shown in FIGS. 1 to 6 operates as follows.
When the button 20 is pressed, an inclined surface or a curved surface (first cam portion 27) formed at the free end of the cam portion 26 presses the cross bar portion 130 of the ladder-shaped main body portion 101. As a result, the main body portion 101 moves along the surface of the lower cover 30 of the case 10. Guide rails 31 are used to control the direction of movement. When the button is pressed, the switch 200 is turned on, and it is detected that the button is operated. According to the detection result, the transmission circuit can transmit a signal corresponding to the button. Further, when the button is pressed, a compression coil spring incorporated in the push button switch biases the button in the direction opposite to the pressing direction.

With the movement of the main body portion 101, the second cam portion 120 provided on the outer side surface of the longitudinal portion 110 acts on the power generation element 300, that is, the movable portion is displaced to generate electric power. This power is supplied to the transmitter circuit. The transmitting circuit receiving the supply of power transmits a signal corresponding to the pressed button to an external control target.
Depending on the type of button, it may be operated by pulling or sliding. Also in this case, the first cam portion is provided in the moving direction of the button, and the power generation element operating portion provided with the first cam follower portion facing the first cam portion is provided. And a through-hole is provided in the main-body part, and let a peripheral part be a 1st cam follower part.
These parts can be molded with resin except for functional parts such as switches and power generation elements. Therefore, it can be manufactured inexpensively as an industrial product.
