DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 and 2 illustrate an installation state of the stopper driving device according to the present invention. As shown in the figure, when the stopper driving device 10 of the present invention moves the window W in the arrow direction (open direction) And the locking device L of the window W is installed in the upper corner of the window frame F on the side close thereto.

3 and 4, the stopper driving device 10 is provided with a case 11 which is located in the corner of the window frame F and is embedded in the window frame F, The window frame 11 is formed in an "a" shape so as to be provided over the window frame horizontal portion F1 and the window frame vertical portion F2.

The case 11 is open at its one side so that a component to be described later can be installed therein, and the opening of the case 11 can be opened and closed by a cover 11a.

A movable bar 12 is provided on the side of the window frame horizontal portion F1 in the case 11 so as to be horizontally moved by the window W when the window W is opened. A part of the movable bar 12 is positioned in the case 11 and the remaining part of the movable bar 12 protrudes out of the case 11 and the window frame F to come in contact with the window W moving in the opening direction, .

A moving shaft 13 is integrally connected to the moving bar 12 located in the case 11 and horizontally moves together with the moving shaft 13. An air compression ring 14 is fixed to an end of the moving shaft 13. An opening 11b is formed in the case 11 for movement of the movable bar 12. [

The pneumatic cylinder 15 is fixed to the window frame horizontal portion F1 side of the case 11 and the air compression ring 14 is located in the pneumatic cylinder 15 so that the rubber material of the moving shaft 13 is horizontally moved An air pressure chamber 15a is provided. The inner circumferential surface of the air pressure chamber 15a and the outer circumferential surface of the air compression ring 14 are in close contact so that the air in the air pressure chamber 15a is compressed by the horizontal movement of the air compression ring 14, And an exhaust hole 15b for discharging the compressed air inside to the outside is formed on one side.

The air pressure generated in the pneumatic chamber 15a is determined by the size of the exhaust hole 15b so that the air pressure reduces the pressing force generated when the window W collides with the moving bar 12, The movement speed of the movable bar 12 is reduced. For example, the larger the size of the exhaust hole 15b, the lower the air pressure due to the large amount of compressed air discharged, the smaller the degree of deceleration of the moving speed of the window W and the moving bar 12, and the smaller the size of the exhaust hole 15b The smaller the discharge amount of the compressed air, the larger the air pressure becomes. Therefore, the degree of deceleration of the moving speed of the window W and the moving bar 12 can be increased.

A coil spring 16 is elastically provided between the moving bar 12 and the pneumatic cylinder 15 so that the coil spring 16 applies an elastic force in a direction in which the moving bar 12 is separated from the pneumatic cylinder 15 have. When the window W moves in the opening direction and the moving bar 12 moves toward the pneumatic cylinder 15, the coil spring 16 is compressed and the window W moves in the closing direction and is separated from the moving bar 12 The movable bar 12 is moved in the direction away from the pneumatic cylinder 15 by the resilient restoring force of the compressed coil spring 16 and restored.

A horizontal guide member 17 is disposed inside the pneumatic cylinder 15 so as to be integrally connected to an end of the moving shaft 13 and the horizontal guiding member 17 moves horizontally with the moving shaft 13 A guide cylinder 18 is formed at the end of the pneumatic cylinder 15 so as to guide the horizontal movement of the horizontal guide member 17.

On the other hand, a vertical guide member 19 is vertically disposed on the side of the window frame vertical portion F2 of the case 11 so as to be vertically movable. And is vertically moved together with the vertical guide member 19.

The case 11 is provided with a guide rail 21 for guiding the vertical movement of the vertical guide member 19 and a guide rail 21 for guiding one side of the ladle 20 to support the vertical movement of the ladle- It is preferable to form the supporting side wall 22 for supporting.

The horizontal guide member 17 provided on the window frame horizontal portion F1 side and the vertical guide member 19 provided on the window frame vertical portion F2 side are connected by a strip spring 23, The horizontal movement of the horizontal guide member 17 is interlocked with the vertical movement of the vertical guide member 19 by the vertical guide member 23.

That is, the band-shaped leaf spring 23 is made of a resilient metal material which can be flexibly deformed and restored, is fixed at one end to the horizontal guide member 17 and at the other end to the vertical guide member 19 And the outer side of the bent portion of the leaf spring 23 is supported by a plurality of support rollers 24 provided in the case 11 so as to be rotatable. Therefore, the plate spring 23 can be flexibly deformed and restored, for example, like a strip-shaped metal-made plate spring used as a tape measure, so that horizontal movement can be converted into vertical movement while bending is maintained in the bent portion .

And a stopper 25 provided on the window frame vertical portion F2 side of the case 11 so as to be rotatable about a single shaft 25a. The stopper 25 is formed with a sector gear 25b centering on the one shaft 25a and engaging with the raiser 20. 4) that protrudes from the case 11 and performs a stopper function (refer to FIG. 6 (a) and FIG. 6 (b)) in accordance with the vertical movement of the rack- Stopper position). An opening 11c is formed in the case 11 for rotational movement of the stopper 25.

The operation of the stopper driving device having such a structure will be described as follows. 4, when the window W is moved in the opening direction (arrow direction) to open the window W, the window W moving in the opening direction is moved in the opening direction of the window frame F F2 and then one side of the window W comes into contact with the moving bar 12 of the stopper driving device 10 at a position close to the window frame vertical portion F2.

As a result, when the movable bar 12 moves together with the force of the window W moving in the opening direction, the coil spring 16 is compressed and the moving shaft 13 and the air compression ring 14 are horizontally moved together, whereby air in the pneumatic chamber 15a of the pneumatic cylinder 15 is compressed.

A resistance force is formed in the direction opposite to the opening direction of the window W by the air pressure compressed inside the pneumatic chamber 15a of the pneumatic cylinder 15. The resistance force causes the window W to move the movable bar 12 It is possible to reduce the moving speed of the window W rapidly. Since the air pressure in the pneumatic chamber 15a is discharged through the exhaust hole 15b, the window W gradually moves in the opening direction.

Subsequently, the horizontal guide member 17 moves in the horizontal direction with the movement of the moving shaft 13 and is guided by the leaf spring 23 connected between the horizontal guide member 17 and the vertical guide member 19, The horizontal movement of the vertical guide member 19 is interlocked with the vertical movement of the vertical guide member 19. [

At this time, since the band-shaped leaf spring 23 is made of a resilient metal material that can be flexibly deformed and restored, the horizontal movement of the horizontal guide member 17 can be performed while maintaining the bending state at the bent portion, And a plurality of support rollers 24 are supported on the bent portion of the leaf spring 23 so that the friction between the leaf spring 23 and the support roller 24 at the bent portion So that it is possible to smoothly move the plate spring 23 in the bent portion.

When the vertical guide member 19 is moved vertically, the stopper 25 is moved vertically by the vertical movement of the case 11 (see FIG. 11) by the sector gear 25b engaged with the stopper 20, (The stopper position in Fig. 4) in the front side (the stopper position in Fig.

6, when the window W is moved in the open direction, the stopper 25 moves to the protruding position to perform the stopper function. That is, when the stopper 25 moves to the projecting position, the window W comes into contact with the end of the stopper 25, and the window W stops moving without moving in the opening direction.

A locking device provided on the window W by a distance between the window W and the window frame F is maintained by the protruded stopper 25 and the lock device And can be prevented from being damaged by colliding with the vertical portion F2. Since the window W is slowly decelerated by the air pressure generated in the pneumatic chamber 15a of the pneumatic cylinder 15 and gradually comes into contact with the end of the stopper 25, the impact force and the impact noise at this time can be minimized have.

When the window W is moved in the closing direction to close the window W, the window W is separated from the moving bar 12 as shown in FIG. 4, The bar 12, the moving shaft 13 and the horizontal guide member 17 are moved in the closing direction of the window W and are guided by a vertical guide member 19 The stopper 25 in which the gear teeth 20 and the sector gear 25b are meshed with each other is also returned to the standby position, that is, into the case 11.

When the window W is opened, the stopper 25 protrudes to the protruding position to perform a stopper function. When the window W is closed, the stopper 25 is inserted into the case 11, so that the appearance of the window frame F can be maintained So that the window frame F can be cleanly cleaned even when the window frame F is cleaned.
