BRIEF DESCRIPTION OF THE DRAWINGS FIG. The diagrammatic bottom view of the principal part. FIG. 3 is a diagrammatic sectional view of a clutch mechanism.

  An outer case that surrounds the end of the pinion shaft is attached to the door closer, and a drive gear that is coaxially attached to one end of the pinion shaft is connected to the speed increaser in the outer case, and this speed increase The first and second switching gears are meshed and engaged with the final gear of the machine via a one-way clutch, respectively, and the generator is connected to the drive gear that is meshed and engaged in common with the first and second switching gears. Are connected coaxially so that the operating direction of the one-way clutch of the first switching gear is connected to the clutch when the door is closed, and the operating direction of the one-way clutch of the second switching gear is connected to the clutch when the door is opened.

Embodiments of the present invention will be described below with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a conventionally known dash pot type door closer, and this door closer 1 is usually mounted on the support side edge upper portion of the inner surface of a door (not shown), and via a link mechanism and a bracket (not shown), It is connected to the frame.

  A boat-shaped outer case 2 is formed on the lower surface of the door closer so as to surround the lower end not connected to the link mechanism among the ends of the pinion shaft that penetrates the cylinder of the door closer 1 in the vertical direction and protrudes upward or downward. Attached

  In the outer case 2, as shown in FIGS. 1 and 2, a speed increaser 5 including a drive gear 4 as a spur gear mounted coaxially on the lower end of the pinion shaft 3 is provided.

  The first and second switching gears 7 and 8 are meshed and engaged with the final stage gear 6 of the speed increaser 5 via a one-way clutch 7, respectively.

  The clutch 7 has a clutch gear 10. On the lower surface of the clutch gear 10, for example, as shown in FIG. 3, an upper surface perpendicular to the paper surface passing through the rotation center axis and a shaft fixed to the switching gears 7 and 8. A bottomed clutch hole 12 is formed in a shape cut out by a lower surface parallel to the upper surface and a pair of coaxial cylinders in contact with the portion 11, and the clutch ball 13 is movably accommodated in the clutch hole 12. Has been.

  3, the clutch gear 10 slips when the clutch gear 10 rotates clockwise relative to the shaft portion 11 in FIG. 3, and the clutch ball 13 moves to the clutch hole 12 when the clutch gear 10 rotates counterclockwise. And the shaft portion 11 are engaged, and the clutch is connected.

The one-way clutch connected to the first cutting gear 8 and the one-way clutch connected to the second switching gear 9 are opposite in the rotation direction of the clutch gear to which the clutch is connected.
In other words, the shape of the clutch hole 12 shown in FIG.

  As shown in FIGS. 1 and 2, a generator 15 is coaxially connected to the drive gear 14 that meshes and engages with the first and second switching gears 8 and 9 in common.

  The power generation mechanism according to one embodiment of the invention described in claim 1 configured as described above is apparent from FIG. For example, when the drive gear 4 is rotated in the door opening direction, the first and second switching gears are rotated in the same direction.

  However, as described above, since the one-way clutches 7 and 7 connected to the first and second switching gears 8 and 9 are connected in opposite directions, the first and second switching gears 8 and 9 are connected to each other. Only one of them rotates to transmit the driving force from the drive gear 4 to the generator 15 via the drive gear 14, and the output from this generator is supplied to, for example, the lamp 16 to illuminate the door when the door is opened. To do.

  On the other hand, when a person passes the door opening and releases the door, the door is closed by the door closer, and the drive gear 4 rotates in the opposite direction to that when the door is opened, and this time the first and second switching gears. Only the other of 8 and 9 rotates to turn the generator 15.

  In the power generation mechanism in the illustrated embodiment, the rotation direction of the generator is opposite between when the door is opened and when the door is closed, but one clutch gear of the first and second switching gears 8 and 9 and the final gear of the speed increaser. When an idle gear (not shown) is inserted between the stepped gears 6, the generator 15 rotates in the same direction when the door is opened and when the door is closed.

  Also in this case, the operating direction of the one-way clutch 7 of the first switching gear 8 is connected to the clutch when the door is closed, and the operating direction of the one-way clutch 7 of the second switching gear 9 is connected to the clutch when the door is opened. Of course, what should be done.

  In the power generation mechanism according to the second aspect of the present invention configured as described above, since the rotation direction of the generator is the same both when the door is closed and when the door is opened, an inexpensive DC motor that can be rotated in one direction is provided. Another advantage is that it can be adopted as a generator.

  The idle gear may be inserted between the first switching gear and the drive gear of the power generation mechanism having the configuration described in the first embodiment. In this case, the idle gear is also described in the second embodiment. The same benefits arise.
