Description

[Detailed description of the invention] (Industrial application field) In the invention, for example, a ventilation plate for opening and closing a ventilation hole formed in a sash frame is urged to one side, pulled to the other side and released to release the ventilation plate. The present invention relates to a device for pulling and releasing an object to be operated, which is provided when the ventilation hole is opened and closed by sliding the device.

(Prior art and its problems) Conventionally, in a ventilator which ventilates by pulling and releasing an operated body such as a ventilation plate, an operating means for pulling and an operating means for releasing are separately provided,
By operating these individually, the ventilation plate was slid.

However, there are drawbacks that the operation by a separate means is troublesome and that many members are exposed to the outside, so that the appearance is impaired.

(Purpose of the invention) The present invention has been made in view of the above circumstances,
Pull the operated object simply by repeating the simple pushing operation.
An object of the present invention is to provide a device for pulling and releasing an operated body that can be released.

(Means for Achieving the Object) In order to achieve the above object, the device for pulling and releasing the operated body according to the present invention is arranged so that it can reciprocate and is biased to one side. Operating means for mounting a slide member connected to the operating body on the other side of the operated body so as to be slidable in the pulling direction, and operating the base to slide the sliding member in the pulling direction by a pushing operation; And a locking piece that reciprocates in a direction substantially orthogonal to the direction of movement of the locking projection formed on the slide member and is urged toward the forward movement side. The sliding edge on the sliding contact side is inclined to the tip end side, and the locking portion is locked at the intermediate portion of the locking edge on the opposite side of the sliding contact edge when the locking piece reciprocates. Forming a step-shaped bent portion that is in sliding contact with the projection; A lock release mechanism for releasing the lock between the locking protrusion and the locking edge is provided on the base end side.

(Operation of the Invention) According to the above configuration, when the operating means is pushed, the slide member slides in the pulling direction, so that the operated body is pulled against the spring force of the spring member and moves to the predetermined position. I do. By the way, during the sliding of the slide member, the locking projection engages with the sliding contact edge of the locking piece and presses downward. Since the sliding contact edge is inclined toward the tip, the locking protrusion moves downward while sliding along the sliding contact edge. For this reason, the locking member is moved backward against the urging force. When the locking projection passes through the tip of the locking piece, the locking member moves forward by the urging force. Therefore, when the pressing on the operating means is released, the slide member is pulled, but the locking edge of the locking piece moves forward while contacting the locking projection, and when the locking projection is engaged with the bent portion, the locking member is engaged. Stops moving. As a result, the locking member is locked to the locking edge of the locking piece, so that the operated body is maintained in the pulled state.

Next, when the operating means is pressed again, the slide member and the locking projection further move in the pulling direction by the spring force of the spring member, so that the locking projection is disengaged from the bent portion of the locking piece, and the locking member is released. The piece is further moved toward the distal end by the urging force.
For this reason, the locking projection relatively moves to the base side of the locking piece. When the hand is released from the operating means, the locking between the locking projection and the locking edge is released by the locking release mechanism, and the slide is performed. The member returns by the spring force of the spring member.

Hereinafter, the present invention will be described with reference to the drawings.

Next, a locking member 32 having a locking piece 32a that reciprocates in a direction substantially perpendicular to the sliding direction of the slide member 30 is rotatably provided on the support shaft portion 37 protruding from the inner wall of the base 29. It is provided in. The locking piece 32 is configured to move forward toward the distal end and toward the base end, and the locking member 32 is urged toward the forward movement by the torsion spring 38. The locking member 32 has a convex portion 44 facing the bent portion 41 of the locking piece 40b, and the base 29 also has a convex portion 45 formed thereon. Both ends of the torsion spring 38 are engaged with these convex portions 44, 45.

A sliding contact edge 40a is formed at the forward end of the locking piece 32a so as to engage with the locking protrusion 33 that moves as the slide member 30 slides. The sliding contact edge 40a is formed so as to be inclined toward the tip. In addition, the locking piece 32
On the side opposite to the sliding contact edge 40a of a, a locking edge 40b is formed to lock the locking projection 33 after sliding so as not to move upward due to the spring force of the spring member 21. A step-shaped bent portion 41 that engages with the locking projection 33 is formed at an intermediate portion of the locking edge 40b, and a locking release mechanism is provided at the base side.

The locking release mechanism includes the torsion spring 38 and the inclined piece 42.
It is composed of The inclined piece 42 is formed by projecting the locking edge 40b to the extension side of the locking projection 33 and inclining downward toward the sliding contact edge 40a.

In the above configuration, when the operating means 31 is pushed, the sector gear 35 rotates, so that the slide member 30 slides downward together with the rack 34 meshing with the sector gear 35.
For this reason, the rope 23 is pulled against the spring member 21, and the ventilation plate 10 slides to a position where it is opened. By the way, during the sliding of the slide member 30, the locking projection 33 is
Engage with the sliding edge 40a of 32a and press downward. Sliding edge 40a
Is inclined toward the tip, so that the locking projection 33 is
It moves downward while sliding along 40a. For this reason,
As shown by the dotted line in FIG. 2B, the locking member 32 is moved backward against the spring force of the torsion spring 38. When the locking projection 33 passes through the tip of the locking piece 32a, the locking member 32 moves forward by the torsion spring 38. Therefore, the operating means 31
When the pressing is released, the slide member 30 is pulled, but the locking edge 40b of the locking piece 32a moves forward while contacting the locking protrusion 33, and when the locking protrusion 33 is engaged with the bent portion 41, As shown in FIG. 3A, the forward movement of the locking member 32 stops. Accordingly, the locking member 32 is locked to the locking edge 40b of the locking piece 32a, so that the tension state of the rope 23 is maintained against the spring member 21. The ventilation hole 9 is opened, and ventilation inside and outside the room is performed.

Next, when the operating means 31 is pushed again, the slide member 30 is pressed.
And the locking projection 33 are further lowered.
Since the engagement of the engagement portion 32a with the bent portion 41 is released and the engagement piece 32a is further moved to the distal end side by the torsion spring 38, the engagement protrusion 32a
33 moves to the base side of the locking piece 32a, and its tip comes into contact with the slope of the inclined piece 42 as shown in FIG. Here, when the hand is released from the operation means 31, the locking projection 33 moves upward along the inclined surface of the inclined piece 42 of the locking piece 32a together with the slide member 30 by the spring force of the spring member 21. At this time, the locking member 32 is tilted by the torsion spring 38 as shown in FIG. 4, and finally the locking between the locking projection 33 and the locking piece 32a is released. The spring plate returns to the upper position by the spring force, and the ventilation plate 10 moves to the closed position.

The operation means 31 for pulling and releasing the cable 23 is not limited to the above example. For example, the slide member 30 is
May be connected to an operation member provided on the outside of the device and pushing the operation member downward.

Further, the locking piece does not need to be configured to reciprocate in the direction substantially perpendicular to the sliding direction of the slide member by the rotation as described above. You may comprise so that it may reciprocate linearly.

Further, the pulling and releasing device does not necessarily have to be for opening and closing the ventilation holes as described above. The present invention can be applied to various mechanisms for reciprocating an operated body such as the ventilation plate 10 in the above-described example.

(Effects of the Invention) As described in detail above, according to the above-described device for pulling and releasing the operated body, the operated body can be pulled and released simply by repeating the pushing operation of the operating means. Very easy.

In addition, since only one operating means is required, the portion exposed to the outside is small, and the appearance of the surroundings is not impaired.
