Description of the Related Art Conventionally, there are an electric lock which supplies power from the outside and an electric lock which has a battery inside and is operated by the electric power. However, the former has to be connected using a long electric wire from an external power supply to a lock, which is troublesome in construction, has a bad external appearance, and is inoperative at the time of a power failure. In addition, the latter has a drawback that it does not operate when the battery life is expired, and in recent years, an electric lock having a power generation function therein has been considered.

FIGS. 15 and 16 are a top sectional view and a sectional front view, respectively, of a main part of a conventional electric lock having a power generating function in the conventional device disclosed in Japanese Patent Application Laid-Open No. 3-208972. A housing, 102 is a rotary generator attached to the housing 101, 103 is a rotary shaft, and a knob 104 that can be extended manually and is rotatable is attached.
Further, a gear 105 is fixed to the intermediate portion. 10
6, 107 are fixed to the housing 101 by guide pins.
Reference numeral 109 denotes a sliding bar provided with an elongated hole 108, which is movable along the guide pins 106 and 107 to a dashed line. Reference numeral 110 denotes a hole provided in the slide bar 109, which is engageable with a stopper 111 projecting from the housing 101. The rack portion 112 can be engaged with and disengaged from the gear 105 alternately. That is, in the state of the solid line, the hole 110 and the stopper 111
Are engaged, and the rack portion 112 and the gear 105 are not engaged. Reference numeral 113 denotes a shaft, on which a bar 114 is slidably supported. One end of the bar 114 is in contact with the sliding bar 109,
The other end is in contact with a plunger 117 of a self-holding solenoid type electromagnetic drive unit 116 having a magnet 115 inside. Reference numeral 118 denotes a spring for urging the plunger 117 in a direction opposite to the attraction force of the magnet 115. A spring 119 presses the sliding bar 109 in the direction of the bar 114. 120 is a bolt for the housing 101
Are slidably engaged with pins 121 and 122 provided on the slide bar by a long hole 123, and are engaged with a concave portion 125 of a slide bar 109 by a protrusion 124. Reference numeral 127 denotes a protrusion provided on the slide bar 109, which rotates the bar 114 counterclockwise in the figure, pushes the plunger 117 at the other end of the bar 114, causes the plunger 117 to be attracted by the magnet 115, and returns to the reset state. I do.

Next, the operation will be described. In the figure,
In the locked state, the slide bar 109 is at the position shown by the solid line, and the rack portion 112 and the gear 105 are not engaged.
Therefore, since the knob 104 can rotate freely, the knob 104 is rotated several times, and the electric power generated by the generator 102 is stored in a capacitor via a rectifier (not shown). Next, a signal obtained by a trouble such as counting pulses of a ten-key magnetic card or a generator is determined through a collation means or the like, and if confirmed, the accumulated power is passed through a switch circuit to an electromagnetic drive unit 116. Turn on electricity. Then, the plunger 117 that has been attracted by the magnet 115 loses its attracting force and projects by the force of the spring 118, and rotates the bar 114 clockwise. As a result, one end of the bar 114 pushes the sliding bar 109 to the position indicated by the dashed line in FIG.
And the gear 105 and the rack portion 112 are brought into an engaged state. When the knob 104 is rotated clockwise in a state where the gear 105 and the rack portion 112 are engaged with each other, the bolt 120 is pulled into the housing 101. During this movement, the projection 127 of the sliding bar 109 pushes one end of the bar 114 and the other end pushes the plunger 117 to attract the magnet 115 to return to the initial state. The door is now openable. Next, when locking the door, after closing the door, the knob 104 is rotated counterclockwise to move the sliding bar 109 to the left to cause the bolt 120 to protrude. When the slide bar 109 is completely protruded, the slide bar 109 is pushed by the force of the spring 119 where the hole 110 of the slide bar 109 and the stopper 111 are located, and returns to the position indicated by the solid line.

[0005]

A shaft 18 implanted on the base 16, a spring 18 as an energy storage means and an elastic member, and a second gear 19 rotatably mounted on the shaft 17 engage with the large gear 5b. A gear 1 meshing with a gear 19a which is a combined gear, a pulley 19b around which one end of the spring 18 is wound, and a gear 25 described later.
9c. Reference numeral 20 denotes a pulley fixed to the base 16 around which the other end of the spring 18 is wound, and reference numeral 21 denotes a shaft 21a.
This is a generator as a power generation means having a function of generating power by rotating the shaft 21a from outside. 22
Is a spring for urging the base 16 against the cam 4.

Although the one-way clutch 23 is not shown in FIG. 1 and a sectional view of the one-way clutch 23 is shown in FIG. 2, in this configuration, the one-way clutch 23 causes the small gear 5a to serve as a drive source. When rotated clockwise, the large gear 5b also rotates clockwise accordingly. However, even if the small gear 5a rotates counterclockwise as a drive source, the large gear 5b does not rotate. Even if the large gear 5b rotates clockwise as a driving source, the small gear 5a does not rotate.

Further, reference numeral 24 denotes a shaft fixed to the base 16, reference numeral 25 denotes mechanical energy supply means, which is rotatably mounted on the shaft 24 and meshes with the large gear 19c of the second gear 19, and reference numeral 26 denotes a gear 25. It is a knob with one. 2
Reference numeral 7 denotes a ratchet as one-way rotation permitting means, which engages with the large gear 5b and restricts the large gear 5b from rotating counterclockwise. Reference numeral 28 denotes a spring for urging the ratchet 27 in the direction of the large gear 5b. A gear group 29 includes a gear 29a meshing with the gear 19c, a gear 29b integral with the gear 29a, and a gear meshing with the gear 29b and fixed to the shaft 21a of the generator 21. The amount of rotation is increased and transmitted to the generator 21. The knob 2 incorporates fingerprint collation means (not shown) for authenticating the user with the user's fingerprint.

In the above configuration, the energy transmission gear group is formed by the gears 19a, 19c, 29a, 29b, and 29c.

Next, the operation will be described. First, spring 1
Assuming that mechanical energy has been stored in FIG. 8, the operation when the door is unlocked and the door is opened will be described with reference to FIG. In the figure, in the locked state, the bolt 6 protrudes from the housing 1 as shown by the dotted line, and the stopper 12 is in the recess 9 of the bolt 6. However, since the groove width of the concave portion 9 is slightly wider than that of the stopper 12, the bolt 6 can move by this clearance. When the user rotates the knob shaft 3 of the knob in the clockwise direction, the cam 4 rotates in the direction of the arrow R1, and the cam 4 causes the base 16 to rotate.
Is pushed down in the direction of arrow R2. By this operation, the large gear 5b of the first gear 5 and the gear 19a of the second gear 19
Are disengaged, and the second gear 19 becomes rotatable. The second gear 19 rotates in the R3 direction due to the rotational force accumulated by the spring 18, and the gear group 29 meshing with the gear 19c of the second gear 19 rotates to drive the generator 21. Here, since the gear group 29 is configured to increase the rotation speed of the gear 19c, the rotation speed of the generator 21 can be increased by the energy accumulated in the spring 18. Therefore, the amount of electric power to be generated also increases. The electric power generated by the generator 21 is stored in a capacitor via a rectifier (not shown).

Next, the user is authenticated through a fingerprint collation unit (not shown), and if the user is authenticated to be unlocked, the stored power is passed through a switch circuit to an electromagnetic drive unit. 10 is energized. Then, the stopper 12 moves in the arrow B direction. Since the electromagnetic drive unit 10 is a bidirectional self-holding solenoid, the electromagnetic drive unit 10 is attracted and held by the magnet 11 without continuing energization. When the stopper 12 comes off the concave portion 9 of the bolt 6, the bolt 6 becomes movable. When the knob shaft 3 of the knob 2 is further rotated, the small gear 5a of the first gear 5 and the rack 7 are rotated.
Are engaged, the bolt 6 moves rightward and the housing 1
And the door is openable and closable.

Next, when the door is to be locked, the door is closed, and when the knob is released from the knob 2, the bolt 6 moves in a direction protruding from the housing 1 by the spring 8, and the gear 5 a is moved by the rack 7 provided on the bolt 6. And the cam 4 rotates counterclockwise. With this operation, the first gear 5a rotates in the counterclockwise direction, but the large gear 5b does not rotate because the drive is cut off because the large gear 5b passes through the one-way clutch 23. After that, the bolt 6 is energized to the electromagnetic drive unit 10 by pressing a switch (not shown), and the stopper 12 separates from the holding force of the magnet 11 and enters the recess 9 of the bolt 6. This is the initial locked state.

Next, the operation of storing energy in the spring 18 will be described. FIG. 4 is a cross-sectional view of a main part showing an operation of storing energy in the spring 18. In the figure, when accumulating mechanical energy, the knob 26 is manually turned by the arrow R.
When rotating in four directions (clockwise), the second gear 19 meshing with the gear 25 rotates in the R5 direction (counterclockwise),
The spring 18 is wound around a pulley 19 b attached integrally with the second gear 19. At this time, the large gear 5b of the first gear 5 meshed with the second gear 19 rotates clockwise. However, as described above, even if the large gear 5b is rotated clockwise as a driving source by the one-way clutch 23, as described above. Small gear 5
a does not rotate. Therefore, even if the knob 28 is rotated, the bolt 6 and the knob 2 are not driven. Further, even if the user tries to rotate the knob 26 in the counterclockwise direction, the rotation cannot be performed because the rotation of the first gear 5b is locked by the ratchet 27. As described above, by rotating the knob 26 extending outside the housing, the spring 18 is wound around the pulley 19b to store mechanical energy used for power generation.

As described above, according to the present embodiment, the first
The configuration of the gear 5 is made up of the small gear 5a and the one-way clutch 23.
, The energy can be stored separately from the opening and closing operation of the door, so that the energy can be stored at a desired timing and the convenience is improved. effective. Also, since the energy for driving the generator is stored in the spring by turning the knob in advance, it is not necessary to use the rotation of the knob for power generation, and the rotation of the knob releases the mesh between the gear 5b and the gear 19b. Since it is used only for releasing mechanical energy, there is an effect that the torque for rotating the knob is small.

In the above embodiment, when the user rotates the knob 26 protruding outside the housing 1, the rotation is transmitted from the gear 25 to the gear 19c, and the spring 18
Although the structure in which the reel 26 is wound around has been described, the knob 19 may not be used, and the gear 19a may be extended and protruded to the outside of the housing 1, and the user may rotate the gear 19a. In this case, the force required for the user to rotate the gear 19a is larger than the force required for rotating the knob 26,
The effect is that the number of rotations required to store mechanical energy is reduced.

In the above embodiment, the ratchet 27 is engaged with the large gear 5b meshing with the gear 19a, and
0 was suppressed, but the ratchet 2 was directly attached to the gear 19a.
7 may be brought into contact with each other to suppress the rotation of the pulley 20. In this case, the ratchet is symmetrical to that of FIG.
What is necessary is just to move to the position which can be engaged. In this case, the large gear 5a and the one-way clutch 23 are not required, and the number of parts can be reduced. In this case, the gear 19a that engages with the ratchet 27 does not mesh with other gears, and thus does not need to have a tooth shape such as an involute, and may have a tooth shape suitable for engaging with the ratchet.

In the above embodiment, the rotation is transmitted to the generator 21 by the gear group 29, but a belt may be used. Further, in the above embodiment, the spring 18 is used as the elastic member, but rubber may be used instead.

Embodiment 2 In the first embodiment, the knob is manually driven to rotate to store the mechanical energy. However, the embodiment in the case where the mechanical energy is stored by using the operation when the door is closed next will be described with reference to FIG. This will be described with reference to FIG. 5 is a cross-sectional view of a main part of the electric lock according to the present embodiment, FIG. 6 is a cross-sectional view of FIG. 5 as viewed from the direction of arrow VV, and FIG. FIG. 8 is a plan view showing the operation of closing the door, and FIG. 9 is a sectional view of a main part showing a state where the bolt 6 is pushed. In these drawings, the same or corresponding members as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

First, the configuration will be described. 5 and 6, reference numeral 4 denotes a mechanical energy releasing means, which is a cam attached to the knob shaft 3 via a one-way clutch 30, and is in contact with the base 16. With this one-way clutch 30, when the knob shaft 3 rotates clockwise as a drive source, the cam 4 also rotates clockwise accordingly, and even when the knob shaft 3 rotates counterclockwise as a drive source, the cam 4 does not rotate. When the cam 4 rotates counterclockwise as a drive source, the knob shaft 3 also rotates counterclockwise, and even when the cam 4 rotates clockwise as a drive source, the knob shaft 3 does not rotate. Reference numeral 31 denotes a gear attached to the knob shaft 3 via a one-way clutch 32, and meshes with the rack 7 of the bolt 6. The gear 31 is rotated integrally with the knob shaft 3 by the one-way clutch 32 when the knob shaft 3 rotates clockwise, and the drive is disconnected from the knob shaft 3 when the knob shaft 3 rotates counterclockwise. With this one-way clutch 32, when the knob shaft 3 rotates clockwise as a driving source, the gear 31 also rotates clockwise accordingly. However, even when the knob shaft 3 rotates counterclockwise as a driving source, the gear 31 does not rotate. . When the gear 31 rotates counterclockwise as a driving source, the knob shaft 3 also rotates counterclockwise. However, even when the gear 31 rotates clockwise as a driving source, the knob shaft 3 does not rotate.

Further, 50 is a third gear rotatable with respect to the knob shaft 3, 50a is a small gear which is a bolt driven gear rotatably attached to the knob shaft 3, and 50b is a small gear 5
This is a large gear, which is a bolt power transmission gear provided via the one-way clutch 23 and a. Due to this one-way clutch 23, when the small gear 50a rotates clockwise as a drive source, the large gear 50b also rotates clockwise accordingly. However, even when the small gear 50a rotates counterclockwise as a drive source, the large gear 50b Does not rotate. Also, the large gear 50
Even if b rotates clockwise as a drive source, the small gear 50a does not rotate.

In FIG. 5, one-way clutch 2
3, one-way clutch 30, one-way clutch 32
Are omitted, and these are shown in cross section in FIG.

In the above configuration, the gears 19a, 19c, 29a, 29b, and 29c form an energy transmission gear group. In the present embodiment, the bolt 6 is a mechanical energy supply unit.

Next, the operation will be described. First, the operation when the door is opened will be described. In the locked state, the bolt 6 protrudes from the housing 1 as shown by the one-dot chain line in FIG. 7, and the stopper 12 is in a state of being inserted into the recess 9 of the bolt 6. However, since the groove width of the concave portion 9 is slightly wider than the stopper 12, the bolt 6 can move by the clearance. 6 and 7, when the user rotates the knob shaft 3 of the knob in the clockwise direction, the one-way clutch 30 transmits this rotation to the cam as described above, and the cam 4 rotates in the clockwise arrow R1 direction. The base 16 is pushed down by the cam 4 in the direction of arrow R2. By this operation, the large gear 50b of the third gear 50 and the gear 19a of the second gear 19 are disengaged from each other, and the second gear 19 becomes rotatable. The second gear 19 rotates in the R3 direction due to the rotational force accumulated by the spring 18, and the gear group 29 meshing with the gear 19 c of the second gear 19 rotates, thereby causing the generator 2 to rotate.
1 is driven. The electric power generated by the generator 21 is stored in a capacitor via a rectifier (not shown).

Next, the user is authenticated through a fingerprint collation unit (not shown), and if the user is authenticated to be unlocked, the stored power is passed through a switch circuit to an electromagnetic drive unit. 10 is energized. Then, the stopper 12 moves in the arrow B direction. When the stopper 12 comes off the concave portion 9 of the bolt 6, the bolt 6 becomes movable. Further, when the knob shaft 3 of the knob 2 is rotated clockwise, the one-way clutch 32 transmits this rotation to the gear 31 to rotate the gear 31 clockwise as described above, and the gear 31 and the rack 7 are engaged. Therefore, the bolt 6 moves rightward in FIG. 7 and the door is openable and closable. After the door is opened, when the hand is released from the knob 2, the bolt 6 is moved leftward in FIG.
More protruding. In this operation, the gear 31 meshing with the rack 7 rotates counterclockwise to rotate the one-way clutch 3
2 rotates the knob shaft 3 in the counterclockwise direction.
Does not rotate because it is attached to the knob shaft 3 via the one-way clutch 30. The cam 4 is returned counterclockwise by a return spring (not shown) and stops at the initial position. When the cam 4 rotates counterclockwise, the knob shaft 3 via the one-way clutch 30 further rotates counterclockwise. The base 16 in contact with the cam 4 rotates counterclockwise and stops at the initial position.

Next, the operation of storing energy in the spring 18 by the operation of closing the door will be described. In the present embodiment, the bolt 6 is a mechanical energy supply unit. FIG. 8 is a plan view showing the operation of closing the door, and FIG. 9 is a sectional view of a main part showing a state where the bolt 6 is pushed. In FIG. 8, reference numeral 33 denotes a fixed side door, and reference numeral 34 denotes a rotating side door to which a power generating lock is attached. At the time of locking, the bolt 6 protrudes from the housing 1 and the tip is a tapered surface 6a. When the door 34 rotates in the direction of arrow R6 from the state shown in FIG. 8, the bolt 6 moves by receiving a force in the direction F shown in FIG. 9 while the tapered surface 6a of the bolt 6 contacts the corner 33a of the fixed door 33. Since the rack 7 is engaged with the small gear 50a of the third gear 50, the third gear 50 rotates clockwise, and the third gear 50
When the second gear 19 meshing with the large gear 50b and the gear 19a rotates counterclockwise, the spring 18
And energy is accumulated. Door 3
When the bolt 4 is closed, the bolt 6 is pushed by the spring 8 and the bolt 6
Is inserted into a groove 35 provided in the door 33 on the fixed side and is locked.

When the bolt 6 moves rightward, the gear 31 meshing with the rack 7 rotates clockwise, but the knob shaft 3 of the knob 2 and the one-way clutch 32
In this case, the knob shaft 3 does not rotate as described above. Since the knob shaft 3 does not rotate, the cam 4 also does not rotate. When the bolt 6 returns to the left, the gear 31 meshing with the rack 7 rotates counterclockwise, and the knob shaft 3 connected to the gear 31 via the one-way clutch 32 also rotates counterclockwise. But cam 4
Is a one-way clutch 3 when the knob shaft 3 rotates clockwise.
The drive is separated and does not rotate because it passes through zero. With the above-described configuration, even if the bolt 6 moves in the locking operation, the cam 4 does not rotate, and the base 16 in contact with the cam 4 does not rotate, so that the third gear 50 and the second gear The gear 19 is not separated.

If the user is not authenticated by the verification means, the door is not opened or closed, and the process ends without storing energy in the spring 18. However, the user stored in the capacitor can be used for subsequent user authentication.

As described above, according to the present embodiment, it is possible to store mechanical energy in the spring by closing the door, and it is not necessary for the user to store mechanical energy.
There is an effect that mechanical energy can be accumulated by a normal closing operation of the door.

Further, since only the bolts similar to those of a normal door protrude from the outside of the housing but the knobs do not protrude, there is an effect that the design is excellent.

Further, if the power generation device for a door according to the present embodiment is used in combination with a battery built in the door, even if the power stored in the capacitor becomes insufficient as a result of the discharge, the authentication can be performed by the power of the battery. In addition, there is an effect that the use period of the battery can be extended.

Embodiment 3 FIG. In Embodiment 2 described above,
Although mechanical energy is stored by moving bolts protruding from the door, a sliding bar protruding from the surface on the rotation support side of the door is next provided. FIG. 1 shows an embodiment for storing energy.
This will be described with reference to FIG. 10 is a cross-sectional view of a main part of the electric lock according to the present embodiment, FIG. 11 is a cross-sectional view of FIG. 10 along the arrow WWWW, and FIG. 12 is a main part of the electric lock unlocked state. FIG. 13 is a sectional view of a main part showing an operation of storing energy in the spring 18, and FIG. 14 is a plan view of a rotation supporting portion of the door. The same or corresponding members as those in the first embodiment or the second embodiment are denoted by the same reference numerals, and description thereof will be omitted.

First, the configuration will be described. 10 and 11, the large gear 5b is provided on the knob shaft 3 via a one-way clutch 23. When the knob shaft 3 rotates clockwise as a drive source by the one-way clutch 23, the large gear 5b also rotates clockwise accordingly. However, even when the knob shaft 3 rotates counterclockwise as a drive source, the large gear 5b rotates. do not do. Even if the large gear 5b rotates clockwise as a driving source, the knob shaft 3 does not rotate.

36 is a sliding bar, 37 is a rack provided on the sliding bar 36, 38 and 39 are holders fixed to the housing 1 for guiding the sliding bar 36, and 40 is a sliding bar 36
A spring for urging in a direction protruding from 4, a stopper 41 for restricting the rightward movement of the slide bar, a shaft 42 fixed to the housing 1, and a rack 43 a rotatably mounted on the shaft 42. The pinion 43b is a bar driven gear that meshes with the pinion 43b.
This is a large gear that is a bar power transmission gear that is mounted via a gear and meshes with the large gear 19c. The large gear 43b is rotated integrally with the small gear 43a when the small gear 43a is rotated clockwise by the one-way clutch 44, and the drive is separated from the small gear 43a when rotated counterclockwise. Reference numeral 45 denotes a plate provided on the door 46 on the fixed side, with which the protruding surface of the sliding bar 36 abuts.

In FIG. 10, the one-way clutch 2
3, one-way clutch 30, one-way clutch 3
2. The display of the one-way clutch 44 is omitted, and these are shown in cross-section in FIG.

In the above configuration, the energy transmission gear group is formed by the gears 19a, 19c, 29a, 29b, and 29c. In the present embodiment, the sliding bar 36 is a mechanical energy supply unit.

Next, the operation will be described. First, the operation when the door is opened by unlocking from the locked state will be described with reference to FIG. In the figure, in the locked state, the bolt 6 protrudes from the housing 1 as shown by the dotted line, and the stopper 12 is in the recess 9 of the bolt 6. However, since the groove width of the concave portion 9 is slightly wider than that of the stopper 12, the bolt 6 can move by this clearance. When the user rotates the knob shaft 3 of the knob in the clockwise direction, the cam 4 rotates in the direction of the arrow R1, and the cam 4 causes the base 16 to rotate.
Is pushed down in the direction of arrow R2. By this operation, the large gear 5b of the first gear 5 and the gear 19a of the second gear 19
Are disengaged, and the second gear 19 becomes rotatable. Further, this operation releases the engagement of the large gear 43b meshing with the large gear 19c. The second gear 19 rotates in the R3 direction due to the rotational force accumulated by the spring 18, and
The gear group 29 meshing with the gear 19c of the gear 19 rotates in the direction of the arrow, and the generator 21 is driven. Here, since the gear group 29 is configured to increase the rotation speed of the gear 19c, the rotation speed of the generator 21 can be increased by the energy accumulated in the spring 18. Therefore, the amount of electric power to be generated also increases. The electric power generated by the generator 21 is stored in a capacitor via a rectifier (not shown).

Next, the user is authenticated through a fingerprint collating means (not shown), and if the user is authenticated to be unlocked, the stored power is passed through a switch circuit to an electromagnetic drive unit. 10 is energized. Then, the stopper 12 moves in the arrow B direction. Since the electromagnetic drive unit 10 is a bidirectional self-holding solenoid, the electromagnetic drive unit 10 is attracted and held by the magnet 11 without continuing energization. When the stopper 12 comes off the concave portion 9 of the bolt 6, the bolt 6 becomes movable. When the knob shaft 3 of the knob 2 is further rotated, the small gear 5a of the first gear 5 and the rack 7 are rotated.
Are engaged, the bolt 6 moves rightward and the housing 1
And the door is openable and closable.

When the knob 2 is released after the door is opened, the bolt 6 moves leftward by the spring 8 and projects from the housing 1. In this operation, the gear 31 engaged with the rack 7 rotates in the counterclockwise direction to rotate the knob shaft 3 in the counterclockwise direction.
The drive is disconnected because it is mounted via the zero. The cam 4 is returned counterclockwise by a return spring (not shown) and stops at the initial position. When the cam 4 rotates counterclockwise, the knob shaft 3 via the one-way clutch 30 further rotates counterclockwise. The base 16 in contact with the cam 4 rotates counterclockwise and stops at the initial position.

Next, the operation of storing energy in the spring 18 by the operation of closing the door will be described. In the present embodiment, the sliding bar 36 is a mechanical energy supply unit. FIG. 13 is a sectional view of an essential part showing an operation of storing energy in the spring 18, and FIG. 14 is a plan view of a rotation support portion of the door.
As shown in FIG. 14, when the door 34 is open, the tip of the sliding bar 36 projects from the door 34 on the rotating side. In this state, when the door 34 is closed in the direction of arrow R7, the tip of the slide bar 36 is pushed and moved in the direction G in FIG. 17 while contacting the plate 45 provided on the fixed-side door 46. Therefore,
The rack 37 moves, and the small gear 43a engaged with the rack 37 rotates clockwise. When the large gear 43b integrated with the small gear 43a via the one-way clutch 44 rotates, the second gear meshed with the large gear 43b is rotated.
The rotation of the gear 19 causes the spring 18 to
b and energy is stored. In the operation of closing the door 34, the protruding bolt 6 reciprocates while abutting on the door 46 on the fixed side. Here, when the bolt 6 moves to the right, the gear 31 meshing with the rack 7 rotates clockwise, but is connected to the knob shaft 3 of the knob 2 via the one-way clutch 32. In this case, the knob shaft 3 does not rotate. Since the knob shaft 3 does not rotate, the cam 4 also does not rotate. When the bolt 6 returns to the left, the gear 31 meshing with the rack 7 rotates counterclockwise, and the knob shaft 3 connected to the gear 31 via the one-way clutch 32 also rotates counterclockwise. However, when the knob shaft 3 rotates clockwise in the clockwise direction, the cam 4 passes through the one-way clutch 30 so that the drive is separated and the cam 4 does not rotate.
With the above configuration, even if the bolt 6 moves in the locking operation, the cam 4 does not rotate, and the base 16 that is in contact with the cam 4 does not rotate, so that the first gear 5 and the second gear 5 are not rotated. The gear 19 is not separated. Similarly, the gear 43b engaged with the gear 19c is engaged without being separated.

If the user is not authenticated by the verification means, the door is not opened or closed, and the process ends without storing energy in the spring 18. However, the user stored in the capacitor can be used for subsequent user authentication.

As described above, according to this embodiment, mechanical energy can be stored in the spring by the operation of closing the door, and the normal door can be closed without providing a driving means for newly winding the spring. There is an effect that mechanical energy can be accumulated by the operation.

Further, since the door generally has inertia when the door is closed, there is an effect that even if the sliding bar is moved, the user hardly feels a load and feels uncomfortable. Further, since the moving direction of the sliding bar is substantially orthogonal to the rotation direction of the door, there is an effect that the load when closing the door is small.

Further, since the direction in which the sliding bar projects is on the side of the rotation supporting portion of the door, there is an effect that the sliding bar is inconspicuous and has excellent design. Further, since the direction in which the sliding bar protrudes is on the side of the rotation support portion of the door, there is an effect that the moving distance of the sliding bar can be easily increased.

In the above embodiment, the ratchet 27 is brought into contact with the large gear 5b meshing with the gear 19a, and
0 was suppressed, but the ratchet 2 was directly attached to the gear 19a.
7 may be brought into contact with each other to suppress the rotation of the pulley 20. In this case, the ratchet is symmetrical to that of FIG.
What is necessary is just to move to the position which can contact a. In this case, the gear 19a and the one-way clutch 23 are not required, and the number of parts can be reduced. In this case, the gear 19a that engages with the ratchet 27 does not mesh with other gears, and thus does not need to have a tooth shape such as an involute, and may have a tooth shape suitable for engaging with the ratchet.

Further, if the power generation device for a door according to the present embodiment is used in combination with a battery built in the door, even if the power stored in the capacitor becomes insufficient as a result of the discharge, the authentication can be performed by the power of the battery. In addition, there is an effect that the use period of the battery can be extended.

Further, according to the present invention, the mechanical energy supply means is a gear projecting out of one of the housings of the energy transmission gear group to the outside. Rotation can be performed, and energy can be stored independently of opening and closing of the door, so that there is an effect that convenience is improved.

According to the present invention, the bolt driven gear and the bolt power transmission gear, which is one of the gears in the energy transmission gear group, are connected via the one-way clutch, and the bolt is connected in any one direction. Only when the bolt moves, the rotation of the bolt driven gear accompanying the movement of the bolt is transmitted from the bolt power transmission gears to the energy transmission gear group to rotate the pulley in a direction in which elastic energy is accumulated. It is possible to accumulate mechanical energy by utilizing the movement of the bolt accompanying the above, and there is an effect that convenience is improved.

Further, according to the present invention, a sliding bar that moves in accordance with opening and closing of a door, a bar driven gear driven by the movement of the sliding bar, and a bar driven gear that is connected to the bar driven gear via a one-way clutch. And a bar power transmission gear meshing with one of the gears in the energy transmission gear group, and the bar driven by the movement of the bar rack only when the slide bar moves in any one direction.
