BACKGROUND ART [0002] Conventionally, an opening / closing body closing device is known as forcibly closing an opening / closing body such as a sliding door. This opening / closing sifting device is constituted of, for example, a catching member provided on the sliding door rail side for guiding the sliding door and a catching / inserting mechanism mounted on the sliding door side.

The catching-in mechanism has a catching member configured to be rotatable about a connecting shaft. The catching member catches or catches the catching member in the form of a projection at a predetermined position that is rotated.

Further, the take-in / take-in mechanism is provided with a spring for pulling it closer to the direction of closing the sliding door and a damper for buffering the spring force.

In this state, when the catching member is not caught by the catching member, the catching-in / pulling-out mechanism prevents the spring force inside the catching member from acting (does not abolish the sliding door). On the other hand, in a state in which the catching member catches the member to be captured, a spring force acts to pull the sliding door in a direction to close the sliding door.

Thus, when the sliding door is closed, the opening and closing body closing device captures the member to be captured by the catching member of the catching and pulling-in mechanism, the sliding door is forcibly guided to the closed position and the sliding door is loosely closed by the damper (See, for example, Patent Documents 1 and 2).

In the above-described opening and closing member eliminating apparatus, when the sliding door runs on the sliding door rail, an operation of engaging (closing) or disengaging (opening) the member to be captured and the catching member of the catching and inserting mechanism occurs at a predetermined position. That is, the catching member is rotated by the opening / closing force of the sliding door at the predetermined position to catch the member to be captured. The speed at which the catching member rotates is at the predetermined position, so that the speed is almost the same as the speed at which the sliding door is closed. Therefore, when the sliding door is attempted to be forcefully disengaged at the predetermined position, the catching member and the member to be captured are vigorously engaged with each other, and a coupling sound is generated. This combined sound may be heard in a disgruntled sound especially when the opening / closing device is installed in a living room of a home.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described circumstances, and an object thereof is to provide an opening / closing body closure device capable of reducing a coupling noise generated when a member to be captured and a catching member of a trapping / inserting mechanism are captured.

In the standby state (the sliding door 2 is in the open state. Figs. 2A to 2C and 11A), the member 11 to be captured is held in the catching / (Left side in the drawing) is farther away from the main body 100 than the other side. In this state, the link pin 140 is positioned below the upper and lower long holes 211b of the guide hole 211, as shown in Fig. 2 (c). Therefore, even if the catch part 100 is to be moved in the front-rear direction (right and left in the drawing), the link pin 140 is fixed and the catch part 100 is not moved.

11 (a), the link pin 140 is positioned below the guide hole 131a of the inclusion block 130, and the inclined hole 111a of the abutment block 110 is inclined And is located at the lower side. That is, the catch plate 120 is located at a relatively lower position with respect to the trapping / inserting mechanism 20. In this state, as shown in Fig. 11 (a), the catching protrusion 121 is located below the protruding portion 11a of the catching member 11, and the catching portion 100 catches the protruding portion 11a Do not capture.

When the sliding door 2 is moved in the closing direction from the state shown in Fig. 11A (standby state), the protruding portion 11a of the catching member 11 is moved in the direction in which the catching block 110 of the catching portion 100 Abut the abutment surface 112a. The abutting surface 112a is pushed rearward (rightward in the drawing) by the protruding portion 11a and the abutment block 110 is pushed rearward (abutment block 110 ) Is pressed).

11 (b), the link pin 140 is pushed upward along the inclined hole 111a in accordance with the movement of the abutment block 110 toward the rear side. Further, the link pin 140 is moved upward along the guide hole 131a of the containment block 130. That is, in this link mechanism, the abutment block 110 is moved rearward relative to the containment block 130. [ Further, in this link mechanism, the trap plate 120 is moved upward relative to the containment block 130. The protruding portion 11a of the captured member 11 is captured in the front and rear direction by the catching portion 112 of the abutment block 110 and the catching protrusion 121 of the catching plate 120. [

Since the length of the guide hole 131a is shorter than the length of the inclined hole 111a, the moving speed of the catching plate 120 can be made lower than the moving speed of the contact block 110 have. That is, the catch plate 120 is moved at a speed lower than the speed at which the sliding door 2 is opened and closed (the moving speed of the butting block 110).

Further, the link pin 140 is moved to the upper side of the upper and lower long holes 211b of the guide portion 210. This fixes the link pin 140 so that the catch part 100 can be freely moved in the forward and backward directions along the longitudinally long holes 211a of the guide part 210 (released state).

In the released state, the catch portion 100 is biased to the right (backward) direction by the tension spring force of the tension spring unit 225. More specifically, the catch part 100 stops moving at the fixed position of the member to be captured 11, and the other part of the catching and pulling-in mechanism 20 except for the catch part 100 is moved forward and backward And moves along the long hole 211a in the relatively forward direction (the left-side direction of the paper surface and the paper-closing direction) (moving state). In other words, the tension spring force of the tension spring unit 225 biases the sliding door 2 in a direction for forcibly closing. Thus, even when the sliding door 2 is half opened, the sliding door 2 is forcibly closed by this spring force, and the sliding door 2 is completely closed (closed state).

On the other hand, in the moving state described above, the spring force of the damper unit 221 is buffered by the spring force of the tension spring unit 225 so that the sliding door 2 does not vigorously hit the door striker 3 .

On the other hand, in the case of opening the sliding door 2 from the closed state (in the case of shifting from the closed state to the moving state), the sliding door 2 is moved rearward (right side in the drawing) in Fig. 11 (b). At this time, the protruding portion 11a abuts on the catching protrusion 121 (more specifically, the tapered contact surface 121a of the catching protrusion 121) of the catching plate 120. In this case, the catch part 100 stops at the fixed position of the member to be captured 11, and the part of the other catching / pulling-in mechanism 20 excluding the catch part 100 is inserted into the front and rear long holes 211a (The right side in the drawing and the opening direction in the drawing). This movement is the direction in which the tension spring 226 of the tension spring unit 225 is tensioned.

When the sliding door 2 is further opened, the link pin 140 immediately comes into contact with the front end of the front and rear long holes 211a of the guide portion 210 (released state). When the sliding door 2 is further opened from this state, the projecting portion 11a of the captured member 11 presses the tapered contact surface 121a of the catching protrusion 121 strongly. As a result, the catching plate 120 linearly slides downward in a direction away from the protruding portion 11a of the catching member 11, that is, downward, along the taper of the tapered contact surface 121a, (140) downward.

At this time, the link pin 140 moves downward along the guide hole 131a of the containment block 130 together with the trapping plate 120. As a result, the trap plate 120 is moved downward relative to the containment block 130 (standby state).

Also, the abutment block 110 moves the link pin 140 obliquely downward to the right along the inclined hole 111a. As a result, the abutment block 110 is moved forward relative to the inclusion block 130 by an amount corresponding to the inclination.

In addition, the urging force of the compression coil spring 113 causes the abutment block 110 to be accelerated (assisted) by the force of forward movement. Thereby, the movement of the link mechanism during the cancellation of release (in the transition from the released state to the standby state) becomes more smooth.

Thereby, the link pin 140 is moved to the lower side of the upper and lower long holes 211b of the guide portion 210. In this state, the movement of the link pin 140 in the left and right direction is fixed and becomes a standby state. Also, the tension spring 226 of the tension spring unit 225 is held in a tensioned state.

According to the opening / closing body closure device according to the embodiment of the present invention, when the protrusion portion 11a of the member 11 to be captured is captured, the catching / inserting mechanism 20 moves the protrusion portion 11a of the member 11 to be captured Since the abutment block 110 is configured to move in the direction in which the abutment block 110 is pushed backward, even if the sliding door 2 is vigorously closed, the urging force against the abutting member 11 can be buffered. This makes it possible to suppress the coupling sound (collision sound) when the abutment block 110 and the protruding portion 11a of the member 11 are brought into contact with each other at the time of acquisition, and the coupling sound can be further reduced.

Since the catching protrusion 121 of the catching plate 120 is moved upward at a speed lower than the speed at which the sliding door 2 is opened and closed, the force of the catching plate 120 moving upward is loosened, (120) can be slowly raised. This makes it possible to suppress a collision sound between the link pin 140 and the upper end portion of the guide hole 131a when the catch plate 120 moves to the upper limit at the time of catching, thereby making it possible to further reduce the operation noise.

The catching / inserting mechanism 20 is constituted by a link mechanism that slides the catching plate 120 and the abutment block 110 by an opening / closing force for moving the sliding door 2 along the guide rail 1 The trapping plate 120, and the abutment block 110 together can be easily realized.

The link mechanism has a link pin 140 mounted on the trapping plate 120 and an induction hole 131a through which the link pin 140 is inserted. The link mechanism 140 guides the trapping plate 120 along the guide hole 131a. The inclined hole 111a through which the link pin 140 is inserted is formed in the abutment block 110. The inclined hole 111a is formed in the abutment block 110. The inclined hole 111a, The trapping plate 120 is moved in the vertical direction along the inclined hole 111a and the inclined hole 111a is moved along the inclined hole 111a relative to the containing block 130 It is possible to move the catch plate 120 and the abutment block 110 together easily.

The link mechanism is provided between the containment block 130 and the abutment block 110 to urge the abutment block 110 in the forward direction at the time of cancellation and to accelerate the movement of the link mechanism at the time of cancellation Since the coil spring 113 is provided, the movement of the link mechanism at the time of cancellation can be lightened.

Further, since the trapping / inserting mechanism 20 is provided with the lock mechanism for retaining the biasing force of the tension spring 226 when the trapping plate 120 is slidably moved and released, the above- The mechanism can be easily configured.

The lock mechanism has a guide hole 211 through which the link pin 140 is inserted and the guide pin 211 is engaged with the link pin 140 in the direction in which the tension spring 226 is biased And the upper and lower long holes 211b for guiding the link pin 140 in the direction different from the direction in which the tension spring 226 is biased by the guiding forward and back long holes 211a, Not only the catching plate 120 and the abutment block 110 are moved by the opening and closing force for moving the guide rail 1 along the guide rail 1 but also the lock mechanism can be easily configured by using the link mechanism described above. Therefore, it is not necessary to provide the lock mechanism separately, and the number of parts can be reduced.

While the present invention has been described with respect to the opening and closing body decanter according to the embodiment of the present invention, the present invention is not limited to the above-described embodiments, and various modifications and changes may be made based on the technical idea of the present invention.

For example, although the sliding door 2 is described in the present embodiment, the present invention is not limited to this. For example, even in the case of opening or closing a drawer, a door of a sliding door on the left or right side, or the like, the present invention can be used as long as it is a device for urging the door in the direction of forcibly closing.

In the present embodiment, the opening / closing body closure device 10 is provided on the upper part of the sliding door, but it may be installed in the lower part. That is, even when the guide rail 1 is attached to the lower edge of the opening, the opening / closing body closure device 10 according to the present invention may be mounted on the lower portion thereof.

In the present embodiment, although the tension spring 226 and the compression coil spring 113 are described as a spring which is an elastic body, it is not limited to a spring. That is, any material that generates an attractive force due to elasticity can be used in the present invention.

In this embodiment, the guide holes 211 (front and rear long holes 211a, upper and lower long holes 211b) formed in the guide portion 210 are formed in an inverted L-shape, But may be formed in other forms based on the moving direction of the spring 140 and the urging direction of the tension spring 226 of the tension spring unit 225. That is, with respect to the forward and backward long holes 211a extending in the same direction as the urging direction of the tension spring 226, if the upper and lower long holes are directed in a direction different from the urging direction of the tension spring 226, So that the locking mechanism can function.
