Description

Detailed Description of the Invention [Object of the Invention] (Industrial Application Field) The present invention relates to a door closing device. Applicable to door closing devices that retract and close automatically.

(Prior Art) In recent years, in the field of automobiles, when a door disposed on a car body so as to be openable and closable is in a half-door state, that is, in a half-latched state,
A door closing device is provided that is forcibly closed to a fully latched state by driving a motor. In this type of door closing device, as disclosed in Japanese Unexamined Patent Publication No. 58-191884, the driving force of a motor is applied to the door! The signal is transmitted to the arm via the magnetic latch, which activates the arm, which activates the door latch and engages the striker on the vehicle body, which automatically pulls the door into the vehicle and fully latches it. I am planning to close it.

With this door closing device, the door tends to go into a half-latched state when the window is closed and the door is operated in the direction of closing due to improved airtightness in the vehicle interior. This is extremely meaningful because the door can be automatically pulled into the interior of the vehicle and closed.

In the door closing device disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 58-191884, as disclosed on page 421 of this publication, when clothes etc. are caught in the door, the electromagnetic clutch When turned off, power transmission from the motor to the arm is cut off, stopping the automatic door closing operation and ensuring safety.

(Problem B to be Solved by the Invention) By the way, in the door closing device disclosed in the above-mentioned Japanese Patent Application Laid-open No. 58-191884, the electromagnetic clutch is turned off in order to stop the automatic closing operation of the door. , the configuration is such that transmission of the driving force of the motor to the arm is blocked. In this way, using an electromagnetic clutch is disadvantageous in terms of space and cost because the electromagnetic clutch is relatively large and expensive.Furthermore, since it is an electric component, it is prone to malfunction and has a reliability problem. is not necessarily sufficient.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to provide a door closing device that can stop the automatic door closing operation without using an electromagnetic clutch by employing a percussion means. It is about providing.

(Structure of the Invention) (Means for Solving the Problems) The door closing device of the present invention is a device for closing a door disposed in a structure such as a vehicle body so as to be openable and closable. A door lock disposed on one side, and a door lock that is disposed on the door lock and releasably locks with a locked part provided on the structure and the other side of the door, and closes the door by locking. a mechanism, a drive mechanism disposed on at least one of the structure, the door, and the door lock, and a transmission mechanism interposed between the drive mechanism and the door locking mechanism, and the drive mechanism directly or indirectly and a first actuating member that is actuated to engage and release the first actuating member, and through the engagement, the driving force of the drive mechanism is transmitted to the door locking mechanism, and the door locking mechanism is activated by the door locking mechanism. A second actuating member that operates in a direction to increase the degree of closing of the door is connected to each other, and the first actuating member and the second actuating member are pivotally supported so as to be relatively rotatable. That is what we are doing.

The door closing device of the present invention is composed of a door lock, a locking mechanism, a driving mechanism, and a transmission groove.

A door lock is located on one side of the structure and the door.

The door locking mechanism has a function of releasably locking a locked portion provided on the other side of the structure and the door, and closing the door by this locking. The door locking mechanism may be a latch mechanism with a pivotable latch or may have other structures such as a hook. Here, the locked portion provided on the other side can be, for example, a striker or a hook. A known striker can be used. The structure in which the door is disposed may include vehicles such as automobiles, trucks, and buses, houses, buildings, ships, and storage structures, as long as the door can be disposed in such a way that it can be freely opened and closed.

The door may be a swinging type that opens and closes by pivoting horizontally or vertically through the structure, or a sliding type that opens and closes by moving linearly back and forth in the horizontal or vertical direction with respect to the structure. Further, the door may be of a type that opens and closes an entrance/exit for people to pass through, a boarding entrance, etc., or it may be of a type that simply opens and closes an opening through which no one passes, such as a window of a structure.

The drive mechanism can be formed using a motor, cylinder, or the like.

In the case of a motor, a speed reduction mechanism can be provided.

The transmission mechanism that characterizes the present invention is interposed between the drive mechanism and the locking mechanism, and has the function of transmitting the driving force of the drive mechanism to the door locking mechanism. The transmission mechanism includes a first actuating member, a second actuating member, and an erroneous connection means. The first actuating member has the function of being actuated directly or indirectly by the drive mechanism. The second actuating member is, for example, lead-shaped;
It can be link-shaped or rod-shaped. The first actuating member may be formed of a single piece or a plurality of pieces. It has the function of operating in the direction of increasing the degree of closure.

Therefore, the second actuating member has an engager such as a pin that engages with the first actuating member. can be formed. The second actuating member may be formed in one piece. The corking means has a function of corking at least one of the second actuating member and the second actuating member by operating the operating portion. The engagement between the first actuating member and the second actuating member is released by the impact, and the automatic opening/closing operation of the door is stopped. As the form of the percussion test, a method of striking at least one of the first actuating member and the second actuating member, or a method of applying pressure while contacting one of the members can be adopted. The plugging means can be, for example, lever-shaped, link-shaped, rod-shaped, or weight-shaped. Alternatively, the plugging means may be a cylinder rod of a cylinder, and the tip of the cylinder rod may be used for the taping. In this case, the operation part for operating the plugging means may be used, for example, to open the door from inside the structure, for example from inside the vehicle. Inside handle for opening/closing operation, or
An outside handle can be used to open and close the door from outside the structure, for example, from outside the vehicle. Alternatively, the operating section may be switches that are manually or automatically operated.

(Operation) When the drive mechanism is driven, the door locking mechanism is activated via the first and second actuation members of the transmission mechanism, and the door is automatically closed.

When the capping means is operated by the operating section, the capping means
and at least one of the second actuating member to release the engagement between the two. As a result, the transmission of the actuation force of the first actuation member to the second actuation member is stopped, and the automatic closing operation of the door is stopped.

It is fixed by. As shown in FIG. 1, the protrusion 61 of the cam lever 56 is fitted into the long hole 63 of the active lever 57. As shown in FIG. 13, the passive lever 58 includes a triangular portion 58a and a projecting piece portion 58b extending from one corner of the triangular portion 58a. Passive lever 5
In the triangular portion 58a of No. 8, an irregularly shaped hole 68 with a large hole area is formed. As shown in FIG. 1, a return spring 69 is interposed between the passive lever 58 and the sub-base 3.

As shown in FIG. 12, the slide lever 59 has a bent piece 7.
0, a long hole 71 is formed. As shown in FIG. 1, the above-mentioned return spring 65 is in pressure contact with the bending piece 70, and constantly biases the bending piece 70 and, in turn, the slide lever 59 in the direction of the force indicated by the arrow CI. As shown in FIG. 4, the elongated hole 71 of the slide lever 59 and the hole 6 of the active lever 57
4'', a pin 73 is inserted into the hole 68'' of the passive lever 58 through a bush 74 and a washer 75, and is pivotally supported.The engagement pin 76 is fixed to the slide lever 59, 57 and is inserted into the irregularly shaped hole 68 of the passive lever 58. In this embodiment, as shown in FIG.
, the active lever 57, the passive lever 58, and the slide lever 59 are stacked and connected by the engagement pin 76. The actuation force of the active lever 57 is transmitted to the passive lever 58 by the engaging pin 76 which rotates around the pin 73 .

As shown in FIG. 1, the cancel lever 60 is held by a pin 36 fixed to the sub-base 3 so as to be rotatable in the directions of arrows DI and D2 coaxially with the inside lever 37. The cancel lever 60 has a contusion part 78 at one end, and a protrusion part 79 and a protrusion part 80 at the other end. As shown in FIG. 1, the protruding piece 24a of the oven lever 24 is located between the protruding piece 79 and the protruding piece 80. Therefore, when the oven lever 24 operates as described above, the cancel lever 60 is rotated in the direction of the arrow D1 or D2 via the protruding piece 79 and the protruding piece 80. Note that 1f is a stopper of the passive lever 58.

(Function of the embodiment) Next, the function of the door closing device described above will be explained along with its usage method.

First, a case will be described in which the open door X is closed only manually. In this case, as shown in FIG. 3, the striker 81 as a locked part on the body Y side is inserted into the U groove 11 of the latch 7 at the position shown by the two-dot chain line a by the spring force of the return spring 9. As door X closes, it enters.

Therefore, being pressed by the striker 81, the latch 7 rotates about the bottle 8 in the direction of the force indicated by the arrow AI, and the claw portion 12 of the latch 7 and the claw portion of the ball 15 are in the fully latched position shown by the two-dot chain line C shown in FIG. 17, thereby maintaining the door X in a fully open state. In this way, when the door X is fully closed only manually, the cam surface 13 of the latch 7 presses the knob 49 of the switch 49, but the cam surface 14 of the latch 7 presses the knob 48 again. Therefore, the switch 49 is maintained in the off state, and therefore the motor 43 is not driven.
Therefore, the cam lever 56, active lever 57, and passive lever 58 do not operate. Of course, even when the door X is opened manually, the switch 49 remains off and the motor 43 does not rotate.

Next, when manually closing the open door X, the manual pressing force may be weak, or the interior of the vehicle may be tightly sealed, resulting in the door X being in a half-latched state. Let's explain the case. In this half-latched state, the latch 7 is already located at the position shown by the solid line in FIG. 3, and in such a half-latched state, the cam surface of the latch 7 is 13 presses the knob 48 of the switch 49, the switch 49 is turned on and the motor 43 is energized.
is driven. Then, as is clear from Fig. 1, motor 4
The driving force of No. 3 is the worm 44, the gears 45a to 45 for deceleration.
c to the rotating shaft 46, and therefore the cam lever 5
6 rotates around the rotating shaft 46 in the direction of arrow G1. At this time, the round bottle-shaped protrusion 61 of the cam lever 56 is engaged with the elongated hole 63, so the active lever 57
Therefore, as shown in FIG. 7, the passive lever 58 is pressed by the engaging pin 76 and operates while pulling the return spring 69, and the projecting piece of the passive lever 58 58b is latch lever 2
0 and move the latch lever 20 in the direction of arrow H1 shown in FIG.
Since the latch 7 rotates integrally with the latch lever 20, the latch 7 rotates about the pin 8 in the direction of the force indicated by the arrow AI to the full latching position shown by the two-dot chain line C in FIG.

Therefore, the rotating latch 7 forcibly draws the door X toward the inside of the vehicle, and eventually the door X is automatically brought into a fully closed state.

In this embodiment, as described above, the motor 43 has a gear 45.
Since the configuration is such that it is turned off after c rotates once,
When the door X is fully closed, the motor 43 automatically stops and the operation of the passive lever 58 also stops. At the same time, the cam lever 56 returns to its original state before the motor 43 was driven and is reset to the position shown in FIG.

By the way, as mentioned above, while the motor 43 is automatically pulling the door X toward the inside of the vehicle body Y from the half latch position to the full latch position, if there is any clothing, fingers, etc. between the door X and the body Y. If you are bitten, open the door
It is necessary to stop the automatic closing operation immediately. That is, as shown in FIG. 7, when the active lever 57 and the passive lever 58 are in the middle of operation, the inside handle inside the vehicle or the outside handle outside the vehicle is activated in an emergency. For example, when the inside handle is activated, the inside lever 3 connected to this
7 is activated, so that the oven lever 24 in FIG. 2 rotates about the bin 23 in the direction of the arrow E1. Also, when the outside handle is operated, the oven lever 24 similarly rotates about the bin 23 in the direction of the arrow E1.

As a result, as shown in FIG. 7, the protruding piece 24a of the oven lever 24 presses the protruding piece 79 of the cancel lever 60, causing the cancel lever 60 to rotate about the bin 36 in the direction of the arrow Di. Therefore, as shown in FIG.
The bent piece 70 is plugged from above to below. Therefore, as shown in FIG. 8, the slide lever 59 slides downward along the elongated hole 64 of the active lever 57 while resisting the spring force of the return spring 65, and the engagement 776 is inserted into the irregularly shaped hole 68 of the passive lever 58. Escape for now.

As described above, the actuation force of the active lever 57 is transmitted to the badge brakeper 58 by the engagement pin 76 that rotates around the pin 73, and since the engagement pin 76 escapes into the irregularly shaped hole 68, the activation force of the active lever 57 is transmitted to the badge brakeper 58. 57 and the passive lever 58 are disengaged. In this released state, even if the active lever 57 is actuated by the cam lever 56, the actuation force of the active lever 57 is not transmitted to the passive lever 58.

At this time, since the oven lever 24 is rotating about the bin 23 in the direction of the arrow E1 shown in FIG. 28 operates in the direction of the arrow, thereby operating the emergency stop switch 27 and turning off the power to the motor 43. Therefore, the automatic closing operation of the door X is stopped, and the door X is no longer closed by the motor 43, so that clothes and fingers are not caught any further.
It's safe.

When the oven lever 24 rotates in the direction of the arrow E1 as described above, the oven link 26 descends as described above.
The contact portion 26a of the oven link 26 is connected to the lift lever 34.
, the lift lever 34 operates in the direction of arrow F1 around the bin 33, the ball 15 interlocking with the lift lever 34 rotates, and the claw 17 of the ball 15 and the claw 12 of the latch 7 are disengaged. Therefore, the spring force of the return spring 9 causes the latch 7 to rotate in the direction of arrow A2 about the bottle 8 to the position shown by the two-dot chain line a in FIG. If you do this, latch 7
The engagement between the U groove 11 and the striker 81 on the body Y side is completely released, and the door X is opened to the body Y.

In addition, as mentioned above, the engagement pin 76 is connected to the passive lever 58.
Even if the bent piece 70 escapes into the irregularly shaped hole 68, the bent piece 70 is biased by the spring force of the return spring 65.
The slide lever 59 is connected to the elongated hole 64 of the active lever 57.
At the same time, the passive lever 58 is also returned to its original position by the spring force of the return spring 69. Therefore, a passive lever 58, an active lever 57, a slide lever 59. The engagement lever 76 is reset again to the condition shown in FIG.

(Effects of Embodiment) As explained above, in this embodiment, the active lever 57, slide lever 59, and passive lever 58 are triple stacked as shown in FIG. 4, which is advantageous for space saving. be. Therefore, it is advantageous to install the door closing device of this embodiment in a narrow space inside the door X. In addition, in this embodiment, a cancel lever 60 is attached to a bin 36 that pivotally supports an inside lever 37 that is conventionally attached to a hem.
Since they are coaxially stacked and arranged, it is advantageous in reducing the number of parts and saving space.

(Other Embodiments) In the embodiment described above, the cam lever 56 rotates once around the rotating shaft 46 to fully close the door X, but this is not limited to this, and other embodiments shown in FIG. As shown in FIG.
6 rotates and the cam lever 56 operates in the direction of arrow G1,
The protrusion 61A of the cam lever 56A is the active lever 57
A is pressed to operate the active lever 57A to the position shown by the two-dot chain line, but after that, the spring force of the return spring 69 causes the active lever 57A to return to its original position. The protrusion 61A of the Naori mulleper 56A comes to rest at a position 61B after a half turn. In this case, the side wall portion 63b forming the elongated hole 63 of the cam lever 56 of the embodiment described above is unnecessary.

Furthermore, as in another embodiment shown in FIG. 13, protrusions 61e and 61r are provided at both longitudinal ends of the cam lever 56B,
By rotating the cam lever 56E in the direction of arrow G2, the active lever 57E is pressed by the protrusion 61e and is operated to the position shown by the two-dot chain line. In this case, when the protrusion 61e is disengaged from the active lever 57E, the spring force of the return spring 69 is applied to the active lever 57E.
E returns to its original position.

The embodiment shown in FIG. 1 described above, and further in FIG. 12.

In each embodiment shown in FIG. 13, the protrusion 61. protrusion 6IA,
Although the cam levers 61B, 61e, and 61f are fixedly held relative to the cam levers 56A and 56E, the present invention is not limited thereto, and rolling elements such as rollers may be used.

Other aspects The door closing device of the present invention is not limited to the embodiments described above and shown in the drawings, and may of course be implemented with appropriate modifications within the scope of the invention.
