Patent Document 1: Japanese Patent Publication No. 2010-95979

The main problem to be solved by the present invention is to be able to construct this kind of assist mechanism while having a simpler and easier assembly.

MEANS TO SOLVE THE PROBLEM In order to achieve the said subject, this invention provides the movable body which combined the assist mechanism of a movable body with the main body so that reciprocation was possible across a reference | standard position and an expanded position, and the to-be-accommodating member provided in either one of this main body, and these An assist mechanism provided on the other side of the apparatus, comprising: a receiving member which catches the receiving member at a predetermined position and assists this moving of the movable body when the movable body is moved back and forth toward the reference position.

The receiving member is rotatably provided at a predetermined angle between the first position and the second position, and is spaced from each other in a direction surrounding the center of rotation, and has a capture portion and a control pin of the member to be accommodated. The capturing member is released by the capturing unit at the first position, or the captive member is released, and the assist is achieved by turning from the capturing state to the second position.

On the side of the receiving member, the slider is provided to be able to slide in a direction insulated from the receiving member and provided with a guide groove for the control pin.

While the slider is pushed in a direction close to the receiving member by the pushing means,

The guide groove is formed to have a corner portion (corner potion) to the push end side is bent or curved outward,

When the receiving member is in the first position, it is assumed that the control pin is configured such that rotation toward the second position of the receiving member is made against the pushing on one side with the corner portion of the guide groove.

The slider is pushed in a direction close to the receiving member, but when the receiving member is in the first position, the control pin is located on one side with the corner of the guide groove, so that the rotation toward the second position of the receiving member is pushed. The state in which the receiving member is in the first position is kept stable. When the receiving member catches the receiving member by the tumbling of the movable body and rotates toward the second position, the slider is moved in the direction against the pushing until the control pin passes over the corner of the guide groove. When the control pin passes over the corner of the guide groove, the control pin enters the pushed back side of the pusher rather than this corner, so the slider is moved to the pushed end of the pusher and rotated toward the second position of the receiving member. Silver is formed by this sticking. As a result, the sliding of the movable body to the reference position is assisted through the receiving member. The housing member and the slider can be properly combined by simply storing the control pin in the guide groove, so that the assembly is easy and the number of parts thereof can be minimized. In addition, by changing the shape of the guide groove, the rotational speed at each position of the accommodation member can be easily changed as necessary.

The receiving member has a coupling pin at a distance between the control pin in the direction surrounding the rotation center,

It has an additional slider which is arrange | positioned so that a receiving member may be located between a slider, and the slide which can be slidably moved in the direction isolate | separated from this receiving member,

The additional slider is provided with a linking groove for the linking pin so that the additional slider is moved away from the receiving member by the rotation toward the second position of the receiving member, and the braking means provides resistance to this movement. There is also a place.

In this manner, the braking force of the braking means can be applied to the rotation toward the second position of the accommodation member, that is, this travel of the movable body that has been assisted by the accommodation member. In addition, the accommodation member and the additional slider can be appropriately combined by simply storing the linkage pin in the linkage groove.

The other side with the corner portion of the guide groove having a groove portion for changing the rotational speed of the receiving member by pushing the pushing means through the slider between the predetermined rotational position and the second position of the receiving member. There is also. In this way, it is typically possible to weaken the assist for the movable body immediately before the movable body reaches the reference position, so that, for example, the door as the movable body does not close out loudly.

The linking groove may be provided with a groove portion for changing or releasing the provision of resistance to the rotation of the accommodation member by the braking means through the additional slider between the predetermined rotational position and the second position of the accommodation member. . In this way, the braking force with respect to the movable body can be zeroed or increased just before the movable body reaches the reference position.

To configure the capture portion of the receiving member to form a pin shape,

The member to be accommodated has a hook shape for allowing the receiving member to enter the hook at a predetermined position when the movable body is moved to the reference position.

The storage recess of the capture section at the reference position when the movable member is moved back and forth from the state where the receiving member is rotated to the second position (malfunction state) without catching the member to be received outside the hook end of the hook-shaped portion. Some parts may be formed. In this way, even if the movable body is swung to the reference position in the malfunctioning state, it is possible to prevent damage to the receiving member and the receiving member.

According to this invention, it has a simple and easy assembly structure, and can implement the mechanism which assists the moving of the movable body to the reference position suitably.

In the example shown, the accommodating member 1 is comprised combining the lower member shown by the code | symbol 14 in FIG. 5, and the upper member shown by the code | symbol 15. In FIG. The lower member 14 has the fan-shaped part 14a and the arm part 14b which protrudes in the horizontal direction from the main position of this fan-shaped part 14a, and the capture | acquisition part 10 is provided at the front-end | tip of the arm part 14b. ) Is formed. The upper member 15 has a fan shape in which the fan-shaped portion 14a of the lower member 14 is mounted on the lower surface thereof, and has a shaft hole 15a through which the vertical axis 11 passes at its main position. The control pin 12 and the connecting pin 13 is provided on the upper surface in a protruding shape.

The slider 3 is provided in the case 2 so that the slide movement of the direction which is closely isolated with respect to the accommodating member 1 is possible. In addition, the slider 3 is formed with a guide groove 30 for receiving the control pin 12. In addition, this slider 3 is pushed by the pushing means 4 in the direction approaching the accommodating member 1.

In the example shown in figure, the slider 3 is the front side standing part 24 formed in the side edge of the side facing the one surface De of the said door Da in the case 2, and the rear side standing part opposite to this. It has a main part 31 which forms a half-shape with the width | variety which accommodates a clearance gap between 25, and is guided to both standing parts 24 and 25, It slides in a longitudinal direction, ie, the left-right direction of door frame Fa. The side portion of the main body 31 facing the center side of the case 2 is stored between the upper surface of the upper member 15 of the housing member 1 and the ceiling plate 23 of the case 2. A thick ear 32 is formed. The guide groove 30 is formed so as to penetrate the ear portion 32 up and down, and the control pin 12 enters the guide groove 30 from below, and the receiving member 1 and the slider 3 are combined. This is being done. Moreover, in the side part toward the edge part 20 side located in the hinge side Db of the door Da in the case 2 in this main-body part 31, it protrudes along the longitudinal direction of the case 2, One end of the rod 33 is integrally connected. An end member indicated by reference numeral 26 is fixed to the end 20 side located at the hinge side Db of the door Da in the case 2, and a through hole 26a formed in the end member 26. The rod 33 is inserted through. A compression coil spring 4 'is wound around and mounted on the rod 33 between the main body 31 and the end member 26. The slider 3 is accommodated by the compression coil spring 4'. It is pushed in the direction approaching (1). In other words, in the illustrated example, the compression coil spring 4 'functions as the pushing means 4.

The guide groove 30 formed as described above on the slider 3 is formed to have a corner portion 30a which makes the pushing end side of the pushing to be bent or curved outward. And, when the receiving member 1 is in the first position, the control pin 12 is one side with the corner portion 30a of the guide groove 30, in the illustrated example, the front end of the guide groove 30 30b), the rotation toward the second position of the receiving member 1 is made against the pushing.

In the illustrated example, the guide groove 30 is not formed as if it follows the arc of a virtual circle about the vertical axis 11. The front end 30b of the guide groove 30 is closer to the end 20 located at the hinge side Db of the door Da in the case 2 than the rear end 30c, that is, the pusher. It is located on the back side of the push. The corner portion 30a is formed at a position approximately midway in the front-rear direction of the guide groove 30.

The slider 3 is pushed in a direction approaching the receiving member 1, but the control pin 12 is caught in the corner portion 30a of the guide groove 30 when the receiving member 1 is in the first position. Since it is located on one side, the rotation toward the second position of the receiving member 1 is opposed to the pushing, so that the state where the receiving member 1 is in the first position is stably maintained. When the receiving member 1 picks up the receiving member 7 and rotates toward the second position by the moving of the movable body D, the control pin 12 rides the corner portion 30a of the guide groove 30. The slider 3 is moved in the direction against the pushing until it is over. When the control pin 12 passes over the corner portion 30a of the guide groove 30, the control pin 12 enters the pushing back side of the pusher than the corner portion 30a, so that the slider 3 The rotation toward the second position of the receiving member 1, which is moved to the pushing end of the pushing, is formed by this pushing. Thereby, the reciprocation to the reference position of the movable body D is assisted through the accommodation member 1.

In the present embodiment, the other side with the corner portion 30a of the guide groove 30 pushed through the slider 3 between the predetermined rotational position and the second position of the accommodation member 1 ( The groove part 30d which changes the rotation speed of the accommodating member 1 by the sticking of 4) is provided. In the illustrated example, the rear end side of the guide groove 30 is located slightly on the pushing end side than the corner portion 30a. Therefore, when the control pin 12 reaches the rear end 30c side of the guide groove 30, the slider 3 is press-fitted slightly in the direction against the pushing by the control pin 12 again, The composition by the pushing of the rotation toward the second position of the housing member 1 is reduced. Thereby, in this embodiment, just before the movable body D reaches a reference position, the said assist with respect to the movable body D is weakened, for example, the door Da as such a movable body D is made. This loud sound is not to be closed.

The additional slider 5 is provided in the case 2 so as to be slidable in a direction insulated from the receiving member 1. Along with this, the additional slider 5 is formed with a linkage groove 50 for receiving the link pin 13. And, by the link pin 13 and the link groove 50, the additional slider 5 is moved in a direction away from the receiving member 1 by the rotation toward the second position of the receiving member 1, The braking means 6 imparts resistance to this movement.

In the illustrated example, the additional slider 5 has a half-shaped main part having a width in which a small gap is accommodated between the front standing portion 24 and the rear standing portion 25 in the case 2 ( It has a main body 51, and is guided to both standing parts 24 and 25 so that it may slide to the longitudinal direction of the case 2, ie, the left-right direction of the door frame Fa. The side portion of the main body 51 toward the center side of the case 2 is stored between the upper surface of the upper member 15 of the housing member 1 and the ceiling plate 23 of the case 2. A thick ear portion 52 is formed. The linkage groove 50 is formed to penetrate the ear portion 52 up and down, and the linkage pin 13 enters the linkage groove 50 from the bottom to accommodate the receiving member 1 and the additional slider 5. The combination with

Moreover, the so-called piston damper 60 which comprises the cylinder 61, the piston which is not shown in figure, and the piston rod 62 connected to this piston are combined in this main-body part 51. As shown in FIG. The piston damper 60 is configured to move the piston in the longitudinal direction of the case 2, that is, the left and right directions of the door frame Fa, and to apply a resistance to the movement of the piston toward the inside of the cylinder 61. It is. In the example shown in the figure, the holding space 51a for accommodating and holding the cylinder 61 of the piston damper 60 is formed in the main body 51 of the additional slider 5. This holding space 51a is open at the side of the main body 51 facing toward the end 21 side located at the free end Df side of the door Da in the case 2, and this end therein. The piston rod 62 protrudes toward 21. An end member indicated by reference numeral 27 is fixed to the end 21 side positioned at the free end Df side of the door Da in the case 2, and the piston rod 62 is attached to the end member 27. Protruding end of the (고정 出 端) is to be fixed. When the additional slider 5 is moved away from the receiving member 1, the piston is pushed into the cylinder 61 through the piston rod 62, and the resistance of the piston damper 60 is reduced to the movement of the additional slider 5. Function. That is, in the illustrated example, such a piston damper 60 is to function as the braking means 6.

The linkage groove 50 formed as described above on the additional slider 5 is also not formed as if it follows the arc of the virtual circle about the vertical axis 11. In addition, the linkage groove 50 is bent at the front end 50a side so that the slider 3 side is bent outward.

When the receiving member 1 is in the first position, the link pin 13 is located at the rear end 50b of the link groove 50 (Figs. 4 and 8). When the receiving member 1 rotates toward the second position, it is pressed by the linking pin 13 so that the additional slider 5 is moved away from the receiving member 1. Thereby, the braking force of the braking means 6 is exerted on the rotation toward the second position of the accommodation member 1, that is, on this movement of the movable body D which has been assisted by the accommodation member 1. have.

With respect to the rotation of the receiving member 1 by the braking means 6 via the additional slider 5, from the predetermined rotational position of the receiving member 1 to the second position in the linkage groove 50. It can be provided with the groove part 50c which changes or releases provision of resistance. In the illustrated example, the free end Df of the door Da in the case 2 between the bent portion 50d of the linkage groove 50 and the front end 50a as it approaches this front end 50a. It extends in the direction which intersects with respect to the longitudinal direction of the case 2 so that the edge part 21 located in the side) may be approached. If the linking pin 13 enters between the bent portion 50d and the front end 50a of the linkage groove 50 just before the receiving member 1 reaches the second position, the additional slider 5 at this time Can not be moved in a direction away from the receiving member 1, or the amount of movement thereof can be reduced. Therefore, in this case, the braking force with respect to the movable body D is zeroed or reduced immediately before the movable body D reaches the reference position, for example, the door as such a movable body D ( The latch bolt constituting a door latch (not shown) provided in Da) can be made to rush at a speed necessary for engaging with the supporting portion of the latch bolt provided on the door frame Fa side.

When the movable body D in the reference position is moved back to the deployed position, the receiving member 7 is captured and the receiving member 1 in the second position is rotated toward the first position. After the slider 3 is moved away from the receiving member 1 by the control pin 12 moved by the control pin 12, the control pin 12 is moved from the corner portion 30a of the guide groove 30 toward the front end side. By the pushing in the closed position, it moves in the direction approaching the receiving member 1, and the state in which the receiving member 1 is in the first position is maintained again. In addition, the additional slider 5 is moved in a direction close to the receiving member 1 by the linking pin 13 which is moved by the rotation of the receiving member 1 and the piston rod 62 in the cylinder 61. Is drawn out to the position before press-fitting.

In the assist mechanism according to the present embodiment, the accommodation member 1 and the slider 3 can be appropriately combined only by storing the control pin 12 in the guide groove 30, so that the assembly is easy. The number of parts can also be made the minimum. In addition, by changing the shape of the guide groove 30, the rotational speed at each position of the accommodation member 1 can be easily changed as necessary. In addition, although not shown, the open lower part of the case 2 is covered with an appropriate cover and is decorated.
