It is shown.

The assist mechanism of the rotating body M according to the present embodiment provides a moving body between the predetermined moving position and the end of the moving position with respect to the moving body M that moves toward the end position of the moving end. It serves to assist.

The pivot M is supported by the support F so that it can be swung and doubled, and typically includes doors and swing doors, but can be swung and swung by the support F. It is sufficient to be supported, and is not limited to these. In the illustrated example, an example in which the assist mechanism is provided in the door Ma and the door frame Fa is shown.

In the example shown in the figure, the door Ma as the rotating body M is brought into contact with the one surface Mb leading at the time of ascension to the door contacting part Fb of the door frame Fa as the support body F. In one closed position (the end position of pulsing), the opening Fc inside the door frame Fa is closed. And when the door Ma as the rotating body M is operated to the said closed position from the open position which does not block the said opening part Fc, it will be provided to the accommodating member 1 which comprises the assist mechanism in this process of this moving. The striker 4 constituting the assist mechanism is brought into contact with each other, so that the assist mechanism is applied to the closed position.

In the example shown, the striker 4 is provided on the door Ma side as the pivot M. As shown in FIG. Therefore, in the example shown, the accommodating member 1 is provided in the door frame Fa side as the support body F. As shown in FIG. Apart from the illustrated example, the striker 4 may be provided on the door frame Fa side as the support body F, and the housing member 1 may be provided on the door Ma side as the pivot M. The king of the body M can be assisted from there.

In the example of illustration, the striker 4 is located in front of the one surface Mb which leads by the striker base 5 at the time of reciprocation in the door Ma. More specifically, in the illustrated example, the striker 4 is provided on the upper side of the door Ma at the door hinge Mc side of the door Ma. The striker base 5 has the attachment part 5a with respect to the door Ma as the rotating body M, and the striker 4 in the front end part 5b located in front of this attachment part 5a. To be supported. This striker 4 is comprised as an axial body which protrudes upwards from the front-end | tip part 5b of the said striker base 5. The upper end of the striker 4 is located at the same level as the upper end of the door Ma or slightly lower than the upper end of the door Ma, and the receiving member is provided on the upper part of the frame of the door frame Fa in the event of a heading toward the closed position of the door Ma. In (1), it captures just before the door Ma is closed. The upper surface of the front end of the striker base 5 is located below the height of the lower part of the main body 2, which will be described later, which accommodates the receiving member 1 in a rotatable manner.

On the other hand, the receiving member 1 is configured to move after capturing the striker 4 at the predetermined moving position of the rotating body M, and assist the moving of the rotating body M to the ending position of the moving body.

In the illustrated example, the receiving member 1 is assembled to the main body 2 so as to be rotatable between the standby position and the gripping position. The main body 2 has an upper portion 2a as an attachment portion to the upper portion of the frame of the door frame Fa, and the receiving member 1 has a vertical axis 2b projecting downward from the upper portion 2a of the main body 2. Is supported by the main body 2 so that rotation is possible.

Moreover, the accommodating member 1 is opened at the said fan-shaped arc-shaped edge 1b, and the capture | acquisition recessed part 1c which recessed toward the shaft hole 1a side from this arc-shaped edge 1b is provided. Formed.

In the illustrated example, the inlet 1d of the trapping recess 1c of the accommodation member 1 is in the standby position toward the side where the door Ma at the time of the movement approaches, that is, the front side. In addition, when the door Ma is moved to a predetermined moving position, the striker 4 is inserted into the trapping recess 1c of the receiving member 1 at this standby position (at the time of the moving operation). Of the concave inner walls 1e and 1f on the inlet 1d side of the capture concave 1c in the standby position, the inner wall 1e on the front side is moved to the side of the movement trajectory z of the striker 4. The inner wall 1f on the rear side is shifted so as to be located on this movement trajectory z (Fig. 2). Then, when the striker 4 is inserted into the capture recess 1c in this manner, the housing member 1 is rotated forward toward the grip position to direct the inlet 1d of the capture recess 1c to the rear side. The stopping force of the fingering means 3 is applied to this forward rotation from the middle thereof, and the sliding direction toward the ending position of the door Ma of the door Ma is assisted by the receiving member 1 which is forwardly rotated as described above.

In the illustrated example, the gripping means 3 fixes one end 3b to the arc-shaped edge 1b side of the receiving member 1, and the other end 3c to the main body 2, It is comprised by the tension coil spring 3a provided in the main body 2 so that the dimension between both end parts 3b and 3c may become the largest in the intermediate position between the standby position and the holding position of the accommodation member 1. The spring 3a assists the movement of the door Ma or maintains the accommodation member 1 in the standby position and the grip position.

That is, in the illustrated example, the spring 3a is most tensioned at the intermediate position located on an imaginary straight line in which both end portions 3b and 3c and the vertical axis 2b are almost identical, whereby the striker 4 If the receiving member 1 accommodated in the capture recess 1c is moved together from the standby position to the position beyond the intermediate position by the sliding of the door Ma, the receiving member 1 is moved from the position beyond the intermediate position. Forcibly rotates forward by the holding force of the spring 3a to the gripping position, and assists the sliding of the door Ma. Further, when the receiving member 1 is in the standby position, forward rotation of the receiving member 1 causes tension of the spring 3a, and also when the receiving member 1 is in the holding position. Since the reverse rotation of) causes tension of the spring 3a, the state where the receiving member 1 is in the standby position and the holding position is held by the spring 3a, respectively. When the braking force is applied by using a damper device or the like not shown in the forward rotation of the accommodation member 1, the assisting of the door Ma may be smoothly performed.

When the door Ma at the end of the swinging operation is double-acted, the receiving member 1 catching the striker 4 is reversely rotated together with the striker 4 to the standby position, and when the standby position is reached, the trapping recess 1c. The striker 4 exits and is released to allow the double acting of the door Ma.

Moreover, in the assist mechanism which concerns on this embodiment, the striker 4 is adjusted by the adjustment means 6 so that a support position may be adjusted in the direction along the rotational direction x of the rotating body M. Is supported).

When the door Ma as the rotating body M is moved to a predetermined reciprocating position, the striker 4 is captured by the housing member 1 and through the striker 4 by the movement of the housing member 1 after the capture. The Wangdong of the door Ma toward the end of Wangwang is assisted. By the way, the assist of the wangung can not be realized unless the striker 4 and the receiving member 1 are properly disposed. In the case where, for example, distortion or warpage or dislocation of the assembly position occurs after the door Ma side as the rotating body M, the door frame Fa side as the support body F, or both, Even when the door Ma is swung, the striker 4 is not properly captured by the housing member 1, so that the desired operation of the assist mechanism cannot be realized. In the present embodiment, the support position of the striker 4 in the direction along the rotational direction of the rotating body M can be adjusted without reattaching the striker base 5 by the adjusting means 6. Thus, inappropriate arrangement of the striker 4 with respect to the housing member 1 caused by the above-described misalignment or the like can be corrected.
