Description

The present invention relates to a socket of a locking mechanism.

In vehicles such as automobiles, a lock mechanism for connecting the door that opens and closes to the body and the body is provided, and the door opening operation is regulated through the lock mechanism. The regulation of the door opening operation by such a locking mechanism is performed, for example, when the door is opened and stopped in a half-opened state during the operation.

The lock mechanism is provided with a connecting portion for connecting the body side and the door side. Then, in the same connecting portion, the body side and the door side are connected by using a socket connected to one of the body side and the door side and a joint member connected to the other of the body side and the door side. I try to do it.

For example, in Patent Document 1, a spherical receiving portion into which a spherical head of a joint member can be movably fitted is formed in a socket, and a snap ring inserted into the spherical receiving portion allows the head from inside the spherical receiving portion. It is described that the socket and the joint member are connected by preventing the socket from coming off. Then, by connecting the socket and the joint member in this way, the connection between the body side and the door side at the connecting portion of the lock mechanism is realized.

Japanese Unexamined Patent Publication No. 10-299818

By the way, when a large load is taken in and out of a vehicle, the connection portion of the lock mechanism between the body and the door, that is, the connection between the body side and the door side by the socket and the joint member, that is, the socket and the joint member There is a desire to break the connection. In order to release the connection, it is necessary to remove the snap ring in the spherical receiving portion of the socket and pull out the head of the joint member from the spherical receiving portion.

However, although Patent Document 1 describes pulling out the snap ring from the spherical receiving portion through the operation of the spring portion located outside the socket, the difficulty of operating the spring portion is unknown. It is not always easy to pull out the head of the joint member from the spherical receiving portion of the snap ring. Therefore, there is room for further improvement in that the connection between the body side and the door side of the lock mechanism can be easily released.

An object of the present invention is to provide a socket of a locking mechanism that can easily release the connection between the body side and the door side.

Hereinafter, means for solving the above problems and their actions and effects will be described.
A socket that solves the above problems is applied to a lock mechanism provided between a door that opens and closes with respect to the body of the vehicle and the body that regulates the opening operation of the door. The socket includes a case that connects to one of the door side and the body side. In this case, an insertion hole for inserting the head of a joint member connected to the other of the door side and the body side into the case, and parallel to the insertion hole so as to be connected to the inner wall surface of the insertion hole. At the same time, an engaging hole having a width smaller than that of the insertion hole is formed. The engaging hole can be separated from the inner wall surface of the insertion hole in a direction in which the joint member moves relative to the case when the door is opened, and a body portion smaller than the head of the joint member can be inserted. It is formed to have a width. Inside the case, an urging member is provided that urges the head of the joint member inserted through the insertion hole toward the engagement hole side.

According to the above configuration, when the socket and the joint member are connected, the head of the joint member is located inside the case with the body of the joint member passing through the engaging hole in the socket case. The head at this position is engaged with the case so as not to be pulled out, and through such engagement, the case (socket) and the joint member are connected, and thus the body side and the door side are connected. Further, the head of the joint member at this time is urged from the insertion hole side to the engagement hole side by the urging member in the case so as not to deviate from the above position.

When disconnecting the body side and the door side, that is, the connection between the socket (case) and the joint member, the joint in the case is moved relative to each other in a direction that opposes the urging force of the urging member. The head of the member is positioned corresponding to the insertion hole of the case. Under this state, the connection between the socket and the joint member is released by pulling out the head of the joint member from the insertion hole to the outside of the case through the relative movement of the joint member and the case in a direction away from each other. In this way, since the connection between the socket and the joint member is released through the relative movement in the two directions described above, the connection between the body side and the door side can be easily released.

The urging member of the socket may urge the head toward the engagement hole side via a pressing member that directly contacts the head of the joint member and presses the head. Conceivable. Further, it is conceivable that the pressing member is positioned corresponding to the insertion hole when it comes into contact with the head of the joint member.

According to this configuration, when the socket (case) and the joint member are connected, the head of the joint member in the case is inserted into an insertion hole by an urging member via a pressing member that directly contacts the head. It is urged from the side toward the engagement hole side. Since the pressing member in the case at this time is located corresponding to the insertion hole, whether or not the contact mode of the pressing member with the head of the joint member is appropriate by visual inspection through the insertion hole from the outside of the case. Can be confirmed.

It is conceivable that the pressing member of the socket sandwiches the head of the joint member with the inner surface of the case.
According to this configuration, when the socket (case) and the joint member are connected, the head of the joint member in the case is sandwiched between the inner surface of the case by the pressing member on which the urging force of the urging member acts. Therefore, it becomes more difficult to shift from the engaged position so as not to be pulled out from the case.

It is conceivable that the pressing member surrounds a part of the joint member around the body when it comes into contact with the head of the joint member.
According to this configuration, when the pressing member comes into contact with the head of the joint member, it not only comes into contact with the head of the joint member but also surrounds a part around the body of the joint member. It becomes difficult to release the contact of the pressing member.

It is conceivable that the pressing member includes an operating portion that penetrates the wall of the case and projects to the outside of the case in the direction of urging the head of the joint member.
The reconnection between the disconnected socket (case) and the joint member is performed in the reverse procedure of the disconnection. When the head of the joint member is inserted into the case through the insertion hole at the time of reconnection, the pressing member in the case is displaced in advance in a direction that opposes the urging force of the coil spring, and the head of the joint member is the case. It is necessary to allow the insertion hole to pass through without being obstructed by the pressing member.

According to the above configuration, when the pressing member is displaced with respect to the case in a direction resisting the urging force of the urging member due to the reconnection of the disconnected case and the joint member, the displacement is operated by the pressing member. This can be easily done by pushing the portion into the case. Since the displacement of the pressing member can be easily performed in this way, the reconnection between the case and the joint member becomes easier.

The cross-sectional view which shows the operation mode of the socket. The cross-sectional view which shows the operation mode of the socket.

Hereinafter, an embodiment of the socket of the lock mechanism will be described with reference to FIGS. 1 to 7.
At the rear of the vehicle shown in FIG. 1, a lock mechanism 3 for connecting the door 2 that opens and closes with respect to the body 1 and the body 1 is provided. The door 2 of this embodiment opens in the flip-up direction with respect to the body 1 (jump-up operation), while closing in the direction opposite to the operation. The door 2 is urged in the flip-up direction (opening direction) with respect to the body 1. The lock mechanism 3 is for regulating the flip-up (opening operation) of the door 2, and is used when the door 2 is stopped in a half-opened state during the flip-up.

The lock mechanism 3 is a connection for connecting the drum 4 provided on the body 1, the wire 5 on which the drum 4 is wound and unwound from the drum 4, and the tip of the wire 5 to the door 2. It is provided with a part 6. The drum 4 rotates in the first rotation direction (the direction in which the wire 5 is fed) when the wire 5 is unwound as the door 2 is flipped up. Further, the drum 4 is urged in the second rotation direction (winding direction of the wire 5), which is the direction opposite to the first rotation direction.

The urging force in the winding direction of the wire 5 acting on the drum 4 is smaller than the urging force in the flip-up direction acting on the door 2. Therefore, when the door 2 flips up with respect to the body 1, the flip-up motion is performed against the urging force acting on the drum 4. The lock mechanism 3 is used when the door 2 is displaced by a predetermined amount toward the closing side by the user during the flipping up of the door 2 of the drum 4, that is, during the rotation in the first rotation direction, that is, the drum 4 is second. It has a function of restricting the rotation of the drum 4 in the first rotation direction when it is rotated by a predetermined amount in the rotation direction.

The above-mentioned function of the lock mechanism 3 makes it possible to stop the door 2 in a half-opened state while it is being flipped up. The lock mechanism 3 rotates the drum 4 in the first rotation direction when the door 2 is displaced by a predetermined amount toward the closing side, that is, the drum 4 rotates in the second rotation direction. At that time, it also has a function of releasing the restriction on the rotation of the drum 4 in the first rotation direction. By such a function of the lock mechanism 3, it is possible to restart the flip-up of the door 2 which is stopped in the half-opened state.

Next, the connecting portion 6 of the lock mechanism 3 will be described.
As shown in FIG. 2, the connecting portion 6 uses a socket 7 connected to one of the body 1 side and the door 2 side, and a joint member 8 connected to the other of the body 1 side and the door 2 side. Therefore, the body 1 side and the door 2 side are connected. The socket 7 includes a case 9 connected to the wire 5. The case 9 of the socket 7 is connected to the body 1 side via the wire 5 and the drum 4 (FIG. 1), and the joint member 8 is connected to the door 2 side by being fixed to the door 2.

On the other hand, the joint member 8 includes a spherical head portion 8a and a body portion 8b connected to the head portion 8a. The body portion 8b of the joint member 8 is formed in a tapered shape whose diameter decreases as it approaches the head portion 8a, and the end portion on the opposite side to the head portion 8a is fixed to the door 2. The head portion 8a of the joint member 8 is inserted into the case 9 of the socket 7 through an insertion hole 21 formed in the case 9.

Next, the socket 7 will be described in detail.
Inside the case 9, a pressing member 10 is provided on the portion of the joint member 8 on the wire 5 side of the head 8a, and a coil spring 11 is provided on the portion of the joint member 8 on the wire 5 side of the pressing member 10. ing. Further, the end of the case 9 on the wire 5 side is open, and a connecting member 12 for connecting the tip 5a of the wire 5 is attached to the opening.

The connecting member 12 has a cylindrical shape into which the tip portion 5a of the wire 5 can be inserted. The tip portion 5a of the wire 5 is locked to the inner bottom of the connecting member 12, and the wire 5 penetrates the bottom and is connected to the tip portion 5a located inside the connecting member 12. A claw 13 is formed on the outer peripheral surface of the connecting member 12. Then, when the connecting member 12 is inserted into the opening portion of the case 9, the claw is fitted into the fitting hole 14 formed in the case 9 to prevent the connecting member 12 from coming off from the case 9.

Inside the case 9, the pressing member 10 is movable in the expansion / contraction direction (substantially left / right direction in FIG. 2) of the coil spring 11. Then, the coil spring 11 urges the pressing member 10 toward the head portion 8a of the joint member 8. As a result, the pressing member 10 comes into contact with the head portion 8a of the joint member 8 and presses the head portion 8a in a direction away from the wire 5 side (to the right in FIG. 2). At this time, the portion of the pressing member 10 in contact with the head 8a of the joint member 8 is sandwiched between the head 8a and the inner surface of the case 9 and is positioned corresponding to the insertion hole 21 of the case 9. Become.

The pressing member 10 protrudes from the portion of the joint member 8 in contact with the head 8a in the right direction (direction away from the wire 5) of FIG. 2 and bypasses the head 8a, and penetrates the wall of the case 9. A plate-shaped operation unit 10a is provided. By pushing the operating portion 10a and relatively moving the pressing member 10 and the case 9 in a direction that opposes the urging force of the coil spring 11, the portion of the pressing member 10 that comes into contact with the head 8a of the joint member 8 is the same head. It is possible to move away from 8a.

FIG. 3 shows a state in which the socket 7 is disassembled. As can be seen from FIG. 3, the connecting member 12 of the socket 7 is formed so that a slit 15 communicating with the inside and outside of the connecting member 12 extends in the same direction as the wire 5. Therefore, with the tip portion 5a of the wire 5 positioned on the open end side (upper side in FIG. 3) of the connecting member 12, the wire 5 is inserted into the connecting member 12 through the slit 15, and the wire 5 is inserted. By pulling in the direction away from the connecting member 12 (downward in FIG. 3), the tip portion 5a of the wire 5 penetrates into the inside of the connecting member 12 and is locked to the bottom of the inside.

After that, the pressing member 10 and the coil spring 11 are inserted into the case 9 in order from the opening portion of the case 9, and the connecting member 12 is further inserted into the opening portion of the case 9. Then, the claw 13 formed on the outer peripheral surface of the connecting member 12 is fitted into the fitting hole 14 of the case 9, so that the pressing member 10, the coil spring 11, and the connecting member 12 are assembled to the case 9. Become.

FIG. 4 shows a state in which the insertion hole 21 in the case 9 and the periphery of the insertion hole 21 are viewed from the front thereof. As can be seen from FIG. 4, the case 9 is formed with an engaging hole 22 having a width smaller than that of the insertion hole 21 which is parallel to the insertion hole 21 so as to be connected to the inner wall surface 21a of the insertion hole 21. The engaging hole 22 is arranged so as to move away from the inner wall surface 21a of the insertion hole 21 in the direction in which the joint member 8 moves relative to the case 9, that is, toward the upper side of FIG. 4 when the door 2 (FIG. 1) is flipped up. , The body portion 8b smaller than the head portion 8a of the joint member 8 is formed to have a width that can be inserted.

When the urging force of the coil spring 11 acts on the joint member 8 via the pressing member 10, the pressing member 10 comes into contact with the head portion 8a of the joint member 8 and surrounds a part of the body portion 8b around the head portion 8a. Also contact. That is, the portion of the pressing member 10 on the joint member 8 side is formed so as to come into contact with the head portion 8a and the body portion 8b of the joint member 8. Further, at this time, the pressing member 10 is in a state of surrounding substantially the entire circumference of the body portion 8b of the joint member 8 with the engaging hole 22 of the case 9. The coil spring 11 at this time serves as an urging member for urging the body portion 8b of the joint member 8 so as to be inserted into the engaging hole 22 side.

Next, the operation of the socket 7 of the lock mechanism 3 will be described.
As shown in FIG. 5, when the socket 7 is connected to the joint member 8, the head portion of the joint member 8 is inside the case 9 with the body portion 8b of the joint member 8 passing through the engagement hole 22 in the case 9. 8a is located. The head 8a at this position is engaged with the case 9 so as not to be pulled out, and through such engagement, the case 9 (socket 7) and the joint member 8 are connected, and by extension, the body 1 side and the door 2 side. And are connected. Further, the head portion 8a of the joint member 8 at this time is urged from the insertion hole 21 side to the engagement hole 22 side by the coil spring 11 in the case 9 so as not to deviate from the above position. Has been done.

When the connection between the body 1 side and the door 2 side, that is, the connection between the socket 7 (case 9) and the joint member 8 is released, both are moved relative to each other in a direction that opposes the urging force of the coil spring 11. As shown in FIG. 6, the head portion 8a of the joint member 8 in the case 9 is positioned corresponding to the insertion hole 21 of the case 9. When the case 9 and the joint member 8 are relatively moved as described above, if the operating portion 10a is pushed into the case 9, that is, in a direction that opposes the urging force of the coil spring 11, the relative movement is performed. It will be easier.

Under the state shown in FIG. 6, as shown in FIG. 7, through the relative movement of the joint member 8 and the case 9 in the direction of being separated from each other, in other words, the relative movement in the direction orthogonal to the direction in which the urging force acts. By pulling out the head portion 8a of the joint member 8 from the insertion hole 21 to the outside of the case 9, the connection between the socket 7 and the joint member 8 is released. After that, the relative position between the socket 7 (case 9) and the pressing member 10 in the direction in which the urging force by the coil spring 11 acts is returned to the position before the disconnection by the urging force of the coil spring 11.

In this way, since the connection between the socket 7 and the joint member 8 is released through the relative movement of the case 9 and the joint member 8 in the above-mentioned two directions, the connection between the body 1 side and the door 2 side is easy. Can be released to.

Further, the reconnection between the disconnected socket 7 (case 9) and the joint member 8 is performed in the reverse procedure of the disconnection. When the head 8a of the joint member 8 is inserted into the case 9 through the insertion hole 21 at the time of reconnection, the pressing member 10 in the case 9 is displaced in advance in a direction that opposes the urging force of the coil spring 11. It is necessary that the head portion 8a of the joint member 8 passes through the insertion hole 21 of the case 9 without being obstructed by the pressing member 10.

The displacement of the pressing member 10 in the case 9 is performed as follows, for example. That is, by pushing the operating portion 10a of the pressing member 10 into the case 9, that is, in a direction that opposes the urging force of the coil spring 11, the pressing member 10 is displaced with respect to the case 9 so as to be in the state shown in FIG. Let me.

After that, the head portion 8a of the joint member 8 is inserted into the case 9 through the insertion hole 21 of the case 9. In this state, when the pushing of the operating portion 10a into the case 9 is stopped, the head 8a of the joint member 8 is moved from the insertion hole 21 side to the engaging hole 22 side in the case 9 by the urging force of the coil spring 11. It is urged toward the case 9 and thereby held in a position where it cannot be pulled out from the case 9 as shown in FIG. In this way, the socket 7 (case 9) and the joint member 8 are reconnected.

According to the present embodiment described in detail above, the following effects can be obtained.
(1) By providing the socket 7 in the connecting portion 6 of the lock mechanism 3, the connection between the body 1 side and the door 2 side can be easily released.

(2) When the socket 7 (case 9) and the joint member 8 are connected, the head 8a of the joint member 8 in the case 9 is coiled via the pressing member 10 that directly contacts the head 8a. It is urged from the insertion hole 21 side toward the engagement hole 22 side by the urging force of the spring 11. Since the pressing member 10 in the case 9 at this time is located corresponding to the insertion hole 21, the contact mode of the pressing member 10 with respect to the head 8a of the joint member 8 by visual inspection from the outside of the case 9 through the insertion hole 21. Can be confirmed whether or not is appropriate.

(3) The head portion 8a of the joint member 8 in the case 9 is engaged with the inner surface of the case 9 by the pressing member 10 on which the urging force of the coil spring 11 acts so as not to be pulled out from the case 9. It is sandwiched in the position where it is. Therefore, when the socket 7 (case 9) and the joint member 8 are connected, the head portion 8a of the joint member 8 in the case 9 is less likely to deviate from the above position.

(4) When the pressing member 10 comes into contact with the head portion 8a of the joint member 8, not only the contact, but also the pressing member 10 surrounds a part around the body portion 8b of the joint member 8. Specifically, the pressing member 10 is in contact with the body portion 8b so as to surround a part around the body portion 8b, and is in contact with the engagement hole 22 of the case 9 so as to surround the entire circumference of the body portion 8b. It becomes. This makes it difficult for the pressing member 10 to be released from contact with the head 8a of the joint member 8.

(5) The pressing member 10 located in the case 9 includes an operating portion 10a that penetrates the wall of the case 9 and projects to the outside of the case 9 in the direction of urging the head 8a of the joint member 8. Therefore, when the socket 7 (case 9) that has been disconnected and the joint member 8 are reconnected, the displacement of the pressing member 10 is displaced with respect to the case 9 in a direction that opposes the urging force of the coil spring 11. This can be easily performed by pushing the operation portion 10a of the pressing member 10 into the case 9. Since the displacement of the pressing member 10 can be easily performed in this way, the reconnection between the case 9 and the joint member 8 becomes easier.

The above embodiment can be changed as follows, for example. The above embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.
-The door and body of the vehicle to which the lock mechanism 3 having the socket 7 is applied do not necessarily have the door flipping up with respect to the body, but the door opens and closes with respect to the body, for example, in the horizontal direction. There may be.

-It is not always necessary to provide the operation portion 10a of the pressing member 10.
When the pressing member 10 comes into contact with the head portion 8a of the joint member 8, it is supposed to surround not only the contact but also a part around the body portion 8b of the joint member 8, but it is not always necessary to do so. There is no.

In the socket 7, the head of the joint member 8 is directly sandwiched between the pressing member 10 and the inner surface of the case 9 in the case 9, but instead of such direct sandwiching, the joint member 8 The head portion 8a may be indirectly sandwiched by sandwiching only the body portion 8b between the pressing member 10 and the case 9 (inner wall of the engaging hole 22). In this case, the head portion 8a is urged to the engagement hole 22 side via the pressing member 10 and the body portion 8b by the urging force of the coil spring 11.

-In the socket 7, the joint member 8 is urged to the head 8a in the case 9 by using the elastic force in the expansion direction of the coil spring 11, but instead of this, the contraction direction of the contraction spring is used. It may be done by using the elastic force of.

-The positional relationship between the socket 7 (case 9) connected to the body 1 side and the door 2 side and the joint member 8 may be reversed. That is, the socket 7 (case 9) may be connected to the door 2 side, and the joint member 8 may be connected to the body 1 side via the wire 5 and the drum 4 of the lock mechanism 3.
