Detailed ways

A typical embodiment of the present invention will be described below with reference to FIGS. 1 to 19( c ). 1 to 11 show a basic structural example of the parts on the collision body 4 side of the booster mechanism to which the present invention is applied, and FIGS. 12 to 19(c) show partial modifications of the parts on the collision body 4 side.

The boosting mechanism of the rotating body M according to this embodiment performs the forward motion of the rotating body M that performs the forward motion toward the forward motion end position from the predetermined forward motion position to the forward motion end position. A mechanism that functions in a boosted (auxiliary) manner.

The rotating body M is supported by the supporting body F so as to be able to rotate forward and backward. Typically, doors and hinged doors can be mentioned, but as long as it is supported by the supporting body F so as to be able to rotate A member that rotates in operation and in return operation is sufficient, and there is no particular limitation. In the illustrated example, an example in which a booster mechanism is provided on the door Ma and the door frame Fa is shown.

In the illustrated example, the door Ma, which is the rotating body M, is in the closed position (the forward stroke end position) in which the front surface Mb of the door frame Fa as the supporting body F hits the front surface Mb during the forward stroke. The inner opening Fc of the door frame Fa is closed. Moreover, when the door Ma as the rotating body M performs a forward stroke operation from the open position that does not close the opening Fc to the above-mentioned closed position, then in the process of the forward stroke, the collision body 4 constituting the booster mechanism will abut against it. Connect to the receiving part 1 that constitutes the booster mechanism, and play the role of the booster mechanism until the closed position.

In the illustrated example, this collision body 4 is attached to the door Ma side which is the rotating body M. As shown in FIG. Therefore, in the illustrated example, the receiving member 1 is provided on the side of the door frame Fa as the support body F. As shown in FIG. Furthermore, unlike the illustrated example, even if the collision body 4 is installed on the door frame Fa side as the support body F, and the receiving member 1 is provided on the door Ma side as the rotating body M, the rotating body can be hit from the middle. M's forward movement is used for boosting.

In the illustrated example, the collision body 4 is positioned by the collision body base 5 in front of the front surface Mb when the door Ma moves forward. More specifically, in the illustrated example, this collision body 4 is equipped on the upper end side of the door Ma on the side of the door hinge Mc of the door Ma. The collision body base 5 has a mounting portion 5a to which a door Ma as a rotating body M is mounted, and supports the collision body 4 in a front end portion 5b located in front of the mounting portion 5a. The collision body 4 is configured as a shaft-shaped body protruding upward from the front end portion 5 b of the collision body base 5 . The upper end of the collision body 4 is located at substantially the same height as the upper end of the door Ma or slightly downward. Capture the collider 4 just before closing. The upper surface of the front end portion of the collision body base 5 is located below the height of the lower portion of the main body portion 2 described later that accommodates the receiving member 1 rotatably.

On the other hand, the receiving member 1 is configured to move after catching the collision body 4 at a predetermined forward movement position of the turning body M, and to assist the forward movement of the turning body M to the forward movement end position.

In the illustrated example, the receiving member 1 is rotatably assembled to the main body 2 between a standby position and a turned-in position. The main body 2 serves as an attachment portion for attaching the top 2a to the frame upper portion of the door frame Fa, and the receiving member 1 is rotatably supported by the main body 2 with a vertical shaft 2b protruding downward from the top 2a of the main body 2 . The receiving member 1 has a substantially fan-shaped outline in a bottom view, and has an axial hole 1 a corresponding to the above-mentioned vertical axis 2 b in a main part of the fan-shaped shape. In addition, the receiving member 1 is formed with a catch recess 1c that opens at the arc edge 1b of the sector shape and is recessed from the arc edge 1b toward the shaft hole 1a side. Furthermore, in the illustrated example, the entrance 1d of the catch recess 1c of the reception member 1 is directed toward the front side, that is, the approach side of the door Ma at the time of the forward stroke at the above-mentioned standby position, and when the door Ma is caused to perform the forward stroke to a predetermined During the going action position, the colliding body 4 enters in the catching recess 1c of the accepting part 1 that is positioned at the standby position (Fig. Of the inner walls 1e, 1f, the front inner wall 1e deviates to the side of the movement locus z of the collision body 4, and the rear inner wall 1f is located on the movement locus z (FIG. 2)). And, when the colliding body 4 enters the catch recess 1c as described above, the receiving member 1 makes the inlet 1d of the catch recess 1c rotate forward to the rearward turning position, and acts on it halfway during the forward rotation. The urging force of the force member 3 assists the forward movement of the door Ma to the forward movement end position by the forwardly rotating receiving member 1 as described above. In the illustrated example, the urging member 3 is constituted by a tension coil spring 3a equipped on the main body 2 in such a manner that one end 3b of the spring is fixed on the side of the arc-shaped edge 1b of the receiving member 1 and the other end 3c of the spring is It is fixed on the main body 2 and the dimension between the two ends 3b, 3c of the spring is at a maximum in the middle position between the standby position and the turned-in position of the receiving part 1 . Moreover, the spring 3a realizes the assisting of the forward movement of the door Ma and the maintenance of the receiving member 1 in the standby position and the turning-in position. That is, in the illustrated example, the spring 3a is stretched the longest at the above-mentioned intermediate position where the two ends 3b, 3c of the spring and the vertical axis 2b are located on substantially the same imaginary straight line, thereby receiving the collision body 4 When the receiving part 1 in the catch recess 1c is moved from the standby position to a position beyond the middle position due to the forward movement of the door Ma, the receiving part 1 moves forward from the middle position due to the biasing force of the above-mentioned spring 3a. The position is forced forward to the turn-in position to boost the forward action of the door Ma. In addition, when the receiving member 1 is in the standby position, the forward rotation of the receiving member 1 causes the stretching of the above-mentioned spring 3a, and, when the receiving member 1 is in the turned-in position, the reverse rotation of the receiving member 1 also causes the stretching of the above-mentioned spring 3a. , and thus the state of the receiving member 1 at the standby position and the state of being at the turned-in position are respectively maintained by the spring 3a. If a braking force is applied to the above-mentioned forward rotation of the receiving member 1 using a damper device (not shown), the forward movement of the door Ma after the boost can be eased. When the door Ma at the end position of the forward stroke is moved back, the receiving part 1 that catches the collision body 4 reverses to the standby position, and when it reaches the standby position, the collision body 4 breaks away from the catch recess 1c and is released. This allows the return action of door Ma.

In addition, in the booster mechanism according to this embodiment, the collision body 4 is supported on the collision body base 5 by the adjustment member 6 so that the support position in the direction substantially along the rotation direction x of the rotation body M can be adjusted.

When the door Ma as the rotating body M is moved to a predetermined forward action position, the collision body 4 is caught by the receiving part 1, and the collision body 4 is used for the collision by the movement of the receiving part 1 after the capture. The forward motion of the door Ma toward the end position of the forward motion is boosted. However, if the colliding body 4 and the receiving member 1 are not properly arranged respectively, the boosting of the forward stroke cannot be realized. In the event that deformation and/or warping and/or a deviation in fitting position etc. occur afterwards on the door Ma side as the rotating body M or the door frame Fa side as the support body F, or both, even if the door Ma is removed The impact body 4 cannot be properly caught by the receiving part 1 and the desired action of the booster mechanism cannot be realized. In this embodiment, the support position of the collision body 4 in the direction substantially along the rotation direction of the rotation body M is adjusted by the above-mentioned adjustment member 6 without reinstallation of the collision body base 5, so that the correction by the above-mentioned Improper arrangement of the collision body 4 relative to the receiving part 1 due to offset or the like.

In this embodiment, the adjustment member 6 is constituted by combining a first part 61 and a second part 62 having the collision body 4 .

The first part 61 is supported on the collision body base 5 so as to be movable in a direction substantially along the rotation direction x of the rotor M. As shown in FIG. On the other hand, the second part 62 has a fitting part 62a that fits the fitted part 61a formed on the first part 61, and can perform fitting from the fitting part 62a to the fitted part 61a. The position is supported on the colliding body base 5 in such a manner that the moving operation to the non-mating position that releases the mating is performed.
