(C) shows a case for accommodating the device of the present invention.

If described in detail the operation of the subject innovation is configured as follows.

Figure 2 and Figure 3 shows the closed state before opening the door (D),

Both ends of the pinion gear 11 are slightly in contact with the opening of the rack gears 12 and 12 ', and the rollers 42 and 42' are each of the first contact portions 41A of the cams 41 and 41 '. ) 41'A, and the idle gears 31 and 31 'are all separated from the second electric gear 22. As shown in FIG.

In this state, as shown in FIG. 4, when the door D is pushed open in the direction of the arrow, the rack gear 12 is linearly contracted according to the rotation of the pinion gear 11 to contract the spring spring 14. The rack gear 12 'is in a state of not being engaged with the pinion gear 11 and maintaining its initial position.

On the other hand, when the pinion gear 11 is rotated, the first motor gear (23) and the cam 41 (41 ') fixed in the same axis are rotated at the same time so that they are engaged with the motor gear (23). 22) and the second electric gear 22 is rotated accordingly,

In addition, the roller 42, which is in contact with the first contact portion 41A in accordance with the rotation of the cams 41 and 41 ', has a second larger rotation radius than the first contact portion 41A as shown in FIG. As it is moved to the contact portion 41B and moved away from the hinge shaft D ', the connecting rod 43 is rotated about the fixed shaft 44 to linearly move the operating rod 46 in the direction of the arrow. As shown in FIG. 4, 42 ′ is moved to a third contact portion 41 ′ C having a relatively smaller radius of rotation than the first contact portion 41 ′ A, and moves toward the hinge axis D ′. As a result, the connecting rod 43 'is rotated about the fixed shaft 44' to linearly move the working rod 46 'in the direction of the arrow.

That is, in the initial position, the roller 42 moves away from the center of the hinge axis D 'and the roller 42' moves closer, so that the two rollers 42 and 42 'have the same rotation radius. The difference in the rotation radius of each contact portion of the cams 41 and 41 'is the same dimension so as to be located at 41B and the third contact portion 41'C so that the moving distance of both rollers 42 and 42' is the same. Of course, it must be designed as.

By pulling and pushing the connecting pieces 47 and 47 'fitted to the engaging pins 46A and 46'A by the operating rods 46 and 46' which are moved in the same movement distance in the opposite directions as described above, 34) The whole is rotated in the direction of the arrow about the fixed shaft 35 so that the idle gear 31 is engaged with the second electric gear 22 being rotated.

As shown in FIG. 7, the idle gear 31 meshing with the second electric gear 22 is in the direction of the arrow where the eccentric ratchet wheel 36B is not disturbed by the pole 36A, that is, the gear for rotation resistance 32. Since it does not interfere with the rotational force of the hinge shaft (D ') because it is rotated in the idling direction that does not transmit the rotational force it is possible to smoothly and quickly open the door (D).

Meanwhile, when the door D is opened in the opposite direction in FIG. 4 as in FIG. 5,

In contrast to FIG. 4, as the rack gear 12 ′ moves linearly as the pinion gear 11 rotates, the spring spring 14 ′ contracts, and the rack gear 12 is not engaged with the pinion gear 11. Keep the initial position.

When the pinion gear 11 is rotated, the first electric gear 21 and the second electric gear 22 are rotated by the rotation of the primary gear 23, and the first contact part is rotated by the cams 41 and 41 ′. The roller 42, which has been in contact with the 41A and 41'A, is moved to the third contact portion 41C having a smaller radius of rotation than the first contact portion 41A as shown in FIG. ') Is moved in a direction close to the connecting rod 43 is rotated about the fixed shaft 44 to move the operating rod 46 in the direction of the arrow, while the roller 42' is the first contact portion ( 41'A is moved to the second contact portion 41'B having a larger radius of rotation than 41'A, and is moved in a direction away from the hinge axis D 'so that the connecting shaft 43' moves the fixed shaft 44 '. As the center is rotated, the operating rod 46 'is linearly moved in the direction of the arrow.

That is, as in FIG. 4, the rollers 42 are close to each other and the rollers 42 'are moved away from each other about the hinge axis D' at an initial position, so that the two rollers 42 and 42 'are spaced apart as much as possible. In being in state to become,

By pushing and pulling the connecting pieces 47 and 47 'fitted to the engaging pins 46A and 46'A by the operating rods 46 and 46' which are moved in the same movement width in the opposite directions. 34) The whole is rotated in the direction of the arrow about the fixed shaft 35 so that the idle gear 31 'is engaged with the second electric gear 22 being rotated.

On the other hand, the idle gear 31 ′ engaged with the second electric gear 22 is rotated in the solid arrow direction as described above in FIG. 7 so that the rotational force of the hinge shaft D 'is not impaired. By opening smoothly and quickly,

As a result, the operation of Figure 5 is the same as the operation of all the means relative to each other on the basis of the operation of Figure 4 and only idle gear 31, 31 'idling.

On the other hand, the closing operation of the open door (D) is based on any one of Fig. 4 or 5, but because it is opposite to each other is not difficult to understand even if a separate additional description will be described with reference to Fig. 4 for convenience of description.

As shown in FIG. 4, when the opening force of the door D is released while the door D is opened, the contracted spring 14 moves the rack gear 12 to the pinion gear 11 and the prime mover 23. ) And the cams 41 and 41 'are provided with the opposite rotational force, the second electric gear 22 and the second electric gear 22 connected thereto by the opposite rotational force applied to the motive gear 23. 7 is provided with a reverse rotational force in the direction of the dotted arrow in FIG. 7 or an eccentric latch wheel 36B integrally formed with the rotational shaft 31A of the idler gear 31 for rotational resistance. Since it cannot be rotated any more because it is caught by the pole 36A coupled to the rotating shaft 32A of the gear 32, the individual rotation of the idle gear 31 is impossible, and only the rotary resistance gear 32 can rotate simultaneously. Therefore, when the rotation resistance gear 32 is rotated so that the rotation resistance is matched thereto The gear 32 'for rotational resistance is also rotated by the coupling gear 33. As a result, the closing force of the hinge shaft D' has to rotate all three gears 32, 32 ', 33. The rotational resistance is generated, the closing speed of the door is slowed down to close slowly, thereby preventing damage to the body.

In the above, the closing speed may be adjusted by adjusting the elastic force of the spring springs 14 and 14 'or by adding or subtracting the number of gears for rotational resistance.

On the other hand, due to the reverse rotation of the cams 41 and 41 'by the closing of the door D, the rollers 42 and 42' come into contact with the first contact portions 41A and 41'A as in the beginning. By the displacement of the rollers 42 and 42 ', the actuating rods 46 and 46' and the support 34 connected thereto are returned to their original positions, and the idle gear 31, which was bitten by the second electric gear 22, is initially It will be dismissed and wait for the next operation.

The present invention as described above, when the door is opened, the connecting gear for driving the power of the hinge shaft is engaged with the idle gear having the anti-rotation function to rotate it in the idling direction, so that the door does not have to resist the opening operation. On the other hand, when the door is closed, the idle gear meshed with the connecting gear rotates in the opposite direction, and the three rotational resistance gears connected to the idle gear are rotated at the same time so that the resistance of the rotation of the door is applied. The slow progress can prevent the physical damage of the person as well as the effect of greatly improving the safety of the door.
