【考案の詳細な説明】 本考案はシヤツタの開閉の両方向の力源として
一つのバネを兼用するようにした開閉駆動装置に
関する。
[Detailed Description of the Invention] The present invention relates to an opening/closing drive device in which a single spring serves as a force source in both directions for opening and closing a shutter.

かつた。
Therefore, when viewed from the rotating shaft of the opening/closing member, the point of action between the spring and the setting member must be closer to the point of action between the opening/closing member and the swinging member. Since the part that receives the action of the spring has to extend long from the main body of the setting member, the setting member has to be large.

また、特にセツト部材が直線運動する形式の場

摩擦抵抗が大きく働くという欠点があつた。
In addition, especially in the case of a type in which the setting member moves linearly, the proportion of the moment that tries to rotate the setting member that should be moved linearly becomes large.
The drawback was that frictional resistance was large.

Therefore, the present invention places the support point of the spring at a position away from the axis of the opening/closing member, and calculates the relative angular displacement of both ends of the spring hung between the opening/closing member and the setting member, as seen from the spring support point. It is set so that a driving force source is generated for the setting member. By making it possible to configure the setting member without requiring an absolute condition that the setting member be located closer than In addition, the present invention provides an opening/closing drive device for a shutter that can change the opening/closing force by reducing frictional resistance during movement and by changing the point of action between the spring and the opening/closing member. be.

This state is shown in FIG. 5 (synchronizer contact piece omitted), but the bending 12b of the iron piece lever 12 is temporarily restrained by the protrusion 2c at the stage of rightward movement of the set plate 2, so the iron piece lever 12 is not completely bent. I can't turn left. Therefore, by turning the swing lever 9 slightly to the right, the end face 9
b and the bend 14a of the opening/closing lever 14 is maintained, and the shutter blades 22 and 23 are aligned with the aperture 1.
Do not keep a closed, but open it a little.
Then, as the set plate 2 continues to move to the right and the protrusion 2c passes the bend 12b, the iron lever 12 is completely rotated to the left and performs the same closing operation as described above.

As described above, the shutter opening/closing drive device of the present invention is capable of controlling the angular displacement of the point of action of the spring with the setting plate when viewed from the support point of the spring in the relationship between one spring, the opening/closing member, and the setting member. Since the driving force is applied to the setting member based on the relationship with the angular displacement of the point of action with the lever, there is flexibility in the support position of the spring and the shape of the setting member, and the opening/closing member's position relative to the spring can be adjusted. By changing the applied point, the opening/closing force can be relatively changed.

[Claims for Utility Model Registration] A shutter blade is arranged to be movable between a first position and a second position, and can be moved from the second position to the first position by a setting operation of the shutter. a set member which is brought to the set member and is provided with a spring-actuated portion; and a rocker which is rotatably disposed on the set member and is provided with the ability to rotate in one direction to a limit position. a movable member; a locking member capable of locking the set member in a first position; and a locking member disposed so as to be rotatable back and forth to open and close the shutter blade, and a locking member capable of locking the set member in a first position; The set member includes a locked part to be locked and a spring acted part, and the set member is moved forward by a movement from a first position to a second position in the locked state with the swinging member. an opening/closing member that opens the shutter blade; a central winding portion of the opening/closing member is inserted into and held by a pin implanted at a position apart from a central axis of rotation of the opening/closing member; , and the other end of the set member is a spring that is respectively engaged with the engaged portion of the set member, and the set member is connected to the first
a spring that acts as a force source for moving the opening/closing member from the first position to the second position and a force source for moving the opening/closing member back; and an opening release that displaces the locking member in a direction to release the locking member from the set member. a device; during the movement of the setting member from the first position to the second position, or at the second position, the swinging member is rotated against the user's habit to release the lock from the opening/closing member; a closing release device for moving the opening/closing member backward to close the shutter blade; and a closing release device for moving the shutter blade from the first position to the second position when the setting member is released from the lock. A shutter characterized in that the angular displacement of the point of action of the spring with the setting member is maintained in a larger relationship than the angular displacement of the point of action of the spring with the opening/closing member when viewed from the support point of the spring. Opening/closing drive device.
