A step portion 56a1 whose diameter is increased upward is provided on the upper end side in the pushed portion 56a, and the lower end of the elastic member 56b is in contact with the step portion 56a1. In the driven portion 56a, a space below the step portion 56a1 functions as a space for loosely inserting a guide rod 56c described later.
Further, as shown in FIG. 5, the free end portion (specifically, the protrusion 12b1) of the swinging member 12b contacts the lower end of the driven portion 56a.

  The elastic member 56 b is a coil spring having a weaker urging force than the urging means in the power generation unit 52. The elastic member 56b has a lower end portion fitted into the upper portion of the driven portion 56a and an upper end portion fitted into the receiving member 56d. The driven portion 56a and the receiving member 56d It is sandwiched between and expands and contracts.

The guide rod 56c is inserted at its lower end into the driven portion 56a and connected to the receiving member 56d at its upper end to guide the expansion and contraction of the elastic member 56b. To stabilize.

The receiving member 56d receives the upper end of the elastic member 56b between the elastic member 56b and the power generation operation body 52a, and is in contact with the power generation operation body 52a via a diaphragm 56e described later.
The receiving member 56d transmits the pressing force on the elastic member 56b side to the power generation operating body 52a at a position shifted in the opening / closing body thickness direction (left-right direction according to FIG. 4).

  The diaphragm 56e is a thin disk-shaped elastic member (for example, rubber) interposed between the upper end of the receiving member 56d and the lower end of the power generation operating body 52a. The diaphragm 56e seals the space on the power generation unit 52 side, and prevents rainwater and the like from entering the power generation unit 52 side from below through a gap on the cylinder portion 51b side.

The power generation unit 52 includes a generator main body 52b fixed in the case 51 and a power generation operation body 52a protruding downward from the generator main body 52b, and the power generation operation body 52a is opened and closed with a predetermined pressing force. Electricity is generated when it is pushed in the opening direction, and thereafter, power generation operation body 52a also generates electricity when it is pushed back in the reverse direction by the urging force of an internal urging means (for example, a coil spring not shown). Do. That is, the power generation unit 52 outputs the generated power twice by the movement in one direction of the power generation operation body 52a and the subsequent movement in the opposite direction.
Note that, for example, a structure described in JP 2013-21746 A or a structure obtained by improving the structure can be applied to the power generation unit 52.

The wireless transmission circuit 53 includes a storage device (for example, a non-volatile memory) that stores information for wireless transmission, a circuit that modulates the information and wirelessly transmits, and a control circuit that operates these according to predetermined conditions ( For example, an electronic circuit including a microcomputer or the like.

Note that the signal transmitted wirelessly as described above includes an identification code unique to the power generation transmission unit 50 in addition to the ON signal or the OFF signal.

  More specifically, when the power generation operating body 52a is pressed, the power generation unit 52 rotates an internal permanent magnet to generate an induced electromotive force. When the power generation operating body 52a returns, the permanent magnet Is rotated in the reverse direction to generate an induced electromotive force in the reverse direction. The wireless transmission circuit 53 wirelessly transmits an ON signal when the current direction of the induced electromotive force is a forward direction, and wirelessly transmits an OFF signal when the current direction of the induced electromotive force is a reverse direction. It has become.

  Note that reference numeral 53a in FIG. 2 is a channel switch for switching the frequency of the radio signal. The channel changeover switch 53a is operated by inserting a jig or the like into the small window 55c opened by removing the small lid 55b (see FIG. 2) of the lid member 55.

The antenna 54 is a rod antenna that is electrically connected to the wireless transmission circuit 53. As shown in FIG. 2 and the like, the antenna 54 is set such that the length in the horizontal direction is considerably longer than the length in the direction orthogonal to the direction (in other words, the thickness or thickness of the antenna 54). The length of the antenna 54 in the lateral direction is longer than the length of the fixed seat 12 and the case 51 in the opening / closing body thickness direction.
The antenna 54 is installed sideways along the opening / closing body width direction.
The mounting structure of the antenna 54 will be described in more detail. The antenna 54 is fitted and fixed to the case 51 via the bracket 54a at the base end side (left end side according to FIG. 3). A portion on the tip side of the portion is located between a rib 51c that protrudes upward from the lower bottom surface of the case 51 and a rib 55a that protrudes downward from the upper bottom surface of the lid member 55. Proximity or contact.
According to this mounting structure, it is possible to effectively prevent the antenna 54 from being detached or damaged from the case 51 and the wireless transmission circuit 53 due to vibrations or shocks associated with the opening / closing operation of the opening / closing body 10.

  In FIG. 2, reference numeral 57 denotes a bracket for fixing the power generation unit 52. According to the illustrated example, the bracket 57 is composed of two plate-like members, but may be configured as one sheet. The bracket 57 is made of a hard metal material (for example, an iron plate or the like), and prevents the generator body 52b from moving upward or rattling due to a pressing force or the like from the fixed seat 12 side.

Next, the characteristic operation and effect of the switchgear 1 having the above-described configuration will be described in detail.
When the movable seat plate 13 moves upward relative to the fixed seat plate 12 by an obstacle coming into contact with the movable seat plate 13 at the lower end of the open / close member 10 during the closing operation of the open / close body 10, FIG. As shown in (b), the elastic member 56 b contracts in the power generation transmission unit 50.

  Then, the movable seat 13 is further lifted, and the upward elastic force by the elastic member 56b side becomes the reaction force on the generator main body 52b side (specifically, the reaction force by the urging means in the power generation unit 52). ), As shown in FIG. 6C, the receiving member 56d rises and the power generation operating body 52a also rises. And by this rise, electric power generation is performed in the generator main body 52b, and the wireless transmission circuit 53 operates by this electric power generation. Accordingly, the wireless transmission circuit 53 wirelessly transmits an ON signal indicating that the movable seat 13 has been raised, the identification code, and the like.

The raised receiving member 56d is in contact with the annular bracket 56f on the generator main body 52b side, so that the amount of rise is regulated.
In addition, the power generation by the power generation unit 52 is performed while the power generation operation body 52a is raised, and stops after the power generation operation body 52a comes into contact with the elastic member 56b.

When receiving the ON signal from the wireless transmission circuit 53, the receiving unit 34 in the storage unit 30 transfers the ON signal to the control circuit 35. Then, the control circuit 35 controls the opening / closing machine 33 or the automatic closing device 36 according to the signal, and stops the closing operation of the opening / closing body 10.
That is, for example, when the switch 33 receives the ON signal during the closing operation of the opening / closing body 10 according to the operation of the operation unit 40, the control circuit 35 controls the opening / closing device 33. The closing operation of the opening / closing body 10 is stopped.
For example, when the control circuit 35 receives the ON signal while the weight of the opening / closing body 10 is lowered by the automatic closing device 36, the control circuit 35 performs the closing operation of the opening / closing body 10 under the control of the automatic closing device 36. To stop.

  When the movable seat 13 is further raised after the wireless transmission, the elastic member is kept in contact with the annular bracket 56f as shown in FIGS. 6 (c) to 6 (d). 56b further contracts, and the movable seat plate 13 contacts the fixed seat plate 12. For this reason, it can prevent that the electric power generation part 52 is damaged by the pressing force from the movable seat board 13 side.

Further, after the above operation, when the upward pressing force applied to the movable seat 13 disappears because the obstacle is removed, the movable movable plate 13 is movable as shown in FIGS. The seat plate 13 is lowered by its own weight, and accordingly, in the power generation transmission unit 50, the pushed portion 56a is lowered while the elastic member 56b is extended.
As shown in FIGS. 7A to 7B, in the initial stage of lowering of the movable seat plate 13, the elastic member 56b extends while the receiving member 56d remains in contact with the annular bracket 56f. Therefore, power generation by the power generation unit 52 is not performed.

  Then, when the movable seat 13 moves downward from the point of time when power is first generated (see FIG. 6C), as shown in FIG. 7C, the receiving member 56d and the power generation operating body 52a are moved. It descends and second power generation is performed in the generator main body 52b. Then, by this power generation, the wireless transmission circuit 53 wirelessly transmits an OFF signal indicating that the movable seat 13 has been lowered, the identification code, and the like.

  When receiving the OFF signal from the wireless transmission circuit 53, the reception unit 34 in the storage unit 30 transfers the signal to the control circuit 35. Then, the control circuit 35 controls the opening / closing device 33 or the automatic closing device 36 in response to the OFF signal to restart the closing operation of the opening / closing body 10.

  Then, the movable seat plate 13 further descends and returns to the initial position (see FIG. 7D) locked to the lower end side of the fixed seat plate 12.

  Therefore, according to the opening / closing device 1 configured as described above, for example, due to the elastic force of the elastic member 56b, even when the ascending speed of the movable seat plate 13 is slow due to, for example, the obstacle being soft. It is possible to raise the power generation operation body 52a vigorously and smoothly. As a result, it is possible to prevent a signal from being transmitted by the wireless transmission circuit 53 due to a shortage of power generated by the power generation unit 52.

  Further, since the protrusion 51a of the case 51 passes through the cover portion 12c and is in contact with the upper surface of the fixed seat plate 12 (see FIG. 5), the thickness of the cover portion 12c is determined according to, for example, fire resistance specifications. Even when this is changed, the stroke of the driven portion 56a can be kept constant, and the operation of the power generation unit 52 can be stabilized.

Further, since the power generation unit 52, the wireless transmission circuit 53, and the antenna 54 are arranged in the opening / closing body width direction and the antenna 54 is provided sideways, the shape of the lower end side of the opening / closing body 10 is slimmed in the opening / closing body thickness direction. Further, it is possible to prevent the power transmission / transmission unit 50 from projecting in the opening / closing body thickness direction and coming into contact with the lintels, objects near the opening / closing device 1 and the like.
In addition, according to the present embodiment, since the power for wireless transmission can be secured by the power generation unit 52, it is not necessary to use a battery, and the power transmission / transmission unit 50 and the seat plate portion of the opening / closing body 10 are slimmed. be able to. In addition, when electric power is insufficient only by the electric power generation amount of the electric power generation part 52, it is also possible to use other electric power, such as a battery, supplementarily.

  In addition, according to the said Example, although the receiving part 34 was provided in the accommodating part 30, you may set it as the aspect which provided the receiving part 34 in the operation part 40, the guide rail 20, etc. as another example. Is possible.
