Description

  The present invention relates to a slide operation device used for a movable louver window, a vehicle center console, an armrest, and the like.

  In the movable louver window, the slat can be opened and closed by an indoor operation, but it is preferable from the viewpoint of crime prevention that the slat does not open when a force is applied to the outdoor slat. Patent Document 1 describes a conventional movable louver window opening / closing operation device that enables such an operation.

The opening / closing operation device described in Patent Document 1 locks a movable member connected to a slat, an operation member that moves the movable member in the vertical direction, and a spring biased so as to protrude and engage the movable member side. The lock member has a slope that converts the displacement of the operation member in the vertical direction into the displacement of the lock member, and a notch into which the lock member enters when the lock member protrudes. In this device, since the lock member is inserted into the notch, the slat 1 does not open and close even when an external force is applied to the slat outdoors. The angle can be adjusted by rotating the slat 1 to enter or exit the notch.
Japanese Patent Laid-Open No. 2002-47868

  However, in the conventional opening / closing operation device described in Patent Document 1, since the opening / closing angle of the slat is stepwise, there is an inconvenience that fine angle adjustment cannot be performed. Further, when the opening / closing angle of the slat is changed, the locking member repeatedly engages with the notch, so that a noise such as a click is generated. For this reason, there is a problem that silent operation cannot be performed. The above-mentioned problems also occur in a vehicle center console, armrest, and the like. With these members, it is difficult to perform angle adjustment and slide adjustment steplessly.

  The present invention has been made in consideration of such conventional problems, and the angle adjustment and slide adjustment of the movable member in the movable louver window and the center console can be adjusted in a stepless manner. An object of the present invention is to provide a slide adjusting device capable of performing a quiet operation without generating noise.

  According to a first aspect of the present invention, there is provided a slide operating device in which an outer member to which an external force can be applied is coupled, a movable member that is movable in the axial direction of the shaft member through the shaft member, and a lock through which the shaft member passes. A pair of shaft members each having a hole is disposed, and is engaged with the shaft member in an inclined manner by contact of the movable member, and the pair of the lock member that locks the movement of the movable member by the engagement; An elastic member disposed between the lock members and biased so as to engage with the movable member in an inclined state, and can be brought into contact with one side of each of the pair of lock members from the outside An outer abutting portion and an inner abutting portion capable of abutting from the inside on each other side of the pair of locking members, and abutting against the movable member by a movement operation along an axial direction of the shaft member. The operation member to move the same member When an external force is applied to the outer member, the movable member abuts on the lock member and the movement of the movable member is locked, and the outer abutment portion contacts one of the lock members by a movement operation to the operation member. The inner abutting portion abuts against the other lock member and the inclination of the pair of lock members is reduced to release the lock.

  In the first aspect of the present invention, since the lock member is inclined with respect to the shaft member, the lock member is engaged with the shaft member, so that the movement of the movable member is locked. In contrast to this state, when an external force is applied to the outer member, the lock member is in a locked state in which the tilted state is maintained. Therefore, angle adjustment and slide adjustment cannot be performed by an operation from the outer member. On the other hand, when the operation member is moved, the operation member comes into contact with the pair of lock members to reduce the inclination of all the lock members. For this reason, the engagement with the shaft member is released, and the angle adjustment and slide adjustment of the outer member are possible.

  The invention according to claim 2 is the slide operation device according to claim 1, wherein the outer contact portion and the inner contact of the operation member with respect to a separation interval at a portion where the operation member contacts the movable member. The separation distance between the portion and the lock member is small.

  A third aspect of the present invention is the slide operation device according to the first or second aspect, wherein the lock member is formed in a plate shape, and the shaft member penetrates horizontally. And

  Invention of Claim 4 is a slide operation apparatus of any one of Claims 1-3, Comprising: The contact part with the said movable member in the said lock member is the same direction as the said contact part. It is characterized by bending.

  According to the present invention, when the operation member is moved with respect to the locked state in which the lock member is engaged with the shaft member, the operation member comes into contact with the lock member and the inclination of the lock member is reduced. For this reason, the engagement of the lock member with the shaft member is released, and angle adjustment and slide adjustment by the operation member are possible. With such a structure, the angle of the outer member can be adjusted steplessly, and quiet operation can be performed without generating noise.

The release posture in which the inclination of the lock plates 13 and 23 for release is eliminated can be secured, and the lock and the release thereof can be surely performed.

  Next, the operation of this embodiment will be described.

  FIG. 3 shows a state in which the slat 1 is completely closed. In this state, when the slat 1 is placed with a hand to open, a clockwise rotational force around the slat shaft 3 acts on the slat 1 and an upward moving force acts on the connecting rod 6. This force acts upward on the apex 21 b of the first contact piece 21 in the slider 12 via the connecting pin 5. Accordingly, the counterclockwise rotational force acts on the first lock plate 13 and the first lock plate 13 tilts, so that the edge portions 13b and 13c of the first lock plate 13 bite into the shaft 10 and the first lock plate 13 13 is locked. When the force to the slat 1 is increased, the force that the edge portions 13b and 13c bite into the shaft 10 is increased and the locking force is increased. As a result, the slat 1 cannot be opened from the outside.

  On the other hand, when a force is applied to close the slat 1 while the slat 1 is open, the same behavior as described above acts on the second lock plate 23. That is, since the vertex 22b of the second contact piece 22 in the slider 12 inclines the second lock plate 23, the edge portions 23b and 23c of the second lock plate 23 bite into the shaft 10 and the second lock plate 23 is locked. The As a result, the slat 1 cannot be closed from outside.

  When the slat 1 is opened indoors, the operation lever 15 is moved upward by holding the operation portion 15m of the operation lever 15. 6 and 7 show the operation in this operation. When the operation lever 15 is moved upward, first, the outer first contact portion 15a of the lever 15 contacts the one end portion 13e of the first lock plate 13 and pushes upward, so that the first lock plate 13 The slider 12 rotates clockwise with the vertex 21b of the first contact piece 21 as a fulcrum. By this rotation, the edge portions 13b and 13c in the lock hole 13a of the first lock plate 13 are released from the shaft 10, and the lock by the first lock plate 13 is released.

  As the operation lever 15 moves upward, the second inner abutment portion 15d of the convex portion 27 abuts against the other end 23f of the second lock plate 23 and pushes upward, so that the second lock plate 23 The slider 12 rotates counterclockwise with the vertex 22b of the second contact piece 22 as a fulcrum. By this rotation, the biting of the edge portions 23b and 23c into the shaft 10 in the lock hole 23a of the second lock plate 23 is released, and the lock by the second lock plate 23 is released. The release of the first lock plate 13 and the second lock plate 23 is completed before the gap (separation interval L5) between the slider-side first contact portion 15e and the first contact piece 21 of the slider 12 disappears. To do.

  Further, when the operation lever 15 is moved upward, the slider-side first contact portion 15e contacts the lower surface of the first contact piece 21 of the slider 12 and moves the slider 12 upward. At this time, since the pair of lock plates 13 and 23 are kept unlocked, they move upward together with the slider 12 without contacting the shaft 10. Since the connecting rod 6 moves upward due to the upward movement of the slider 12, the slat 1 can be rotated clockwise to open the slat 1.

  When the slat 1 is closed indoors, the operating portion 15m of the operating lever 15 is grasped and moved downward. Thereby, the operation | movement mentioned above acts reversely up and down. That is, first, the outer second contact portion 15b contacts the one end portion 23e of the second lock plate 23 and rotates the second lock plate 23 counterclockwise, so that the lock by the second lock plate 23 is released. The Further, the inner first contact portion 15c contacts the other end portion 13f of the first lock plate 13 to rotate the first lock plate 13 in the clockwise direction, so that the lock on the first lock plate 13 is released. Thereafter, the slider-side second contact portion 15f contacts the second contact piece 22 of the slider 12 to move the slider 12 downward. Thereby, the slat 1 can be closed.

  In both the opening operation and the closing operation of the slat 1 described above, when the movement operation of the operation lever 15 is stopped, the first lock plate 13 and the second lock plate 23 are respectively moved by the urging force of the spring 14 to the apex 21b of the slider 12 and 22b is inclined as a fulcrum, and the edge portions 13b, 13c and 23b, 23c of the respective lock holes 13a, 23a bite into the shaft 10 to be locked. Thereby, since rotation of the slat 1 stops at the angle, the opening angle and the closing angle of the slat 1 can be adjusted steplessly. In addition, when the operation lever 15 is moved up and down, all the lock plates 13 and 23 do not bite into the shaft 10, so that no abnormal noise is generated and there is no uncomfortable feeling and the operation can be performed quietly. .
