The fixed cylinder 20 having such a configuration is fixed to the case 4d of the automatic locking assembly 4 and can be fixed to the window 3 together with the case 4d as shown in Fig. It is preferable to firmly fasten the base plate. The wall of the stationary cylinder 20 opposite to the first through hole 21 can be separated from and connected to the stationary plate 25 so that the movable cylinder 30 and the urging member 40 can be engaged with the stationary cylinder 20, So that it can be installed inside.

The movable cylinder 30 is provided so as to be movable in the opening and closing direction of the window 3 through the first through hole 21 of the fixed cylinder 20 in the fixed cylinder 20. [ A first latching jaw 32 having an acceleration exhaust groove 31 corresponding to the latching jaw 24 having the acceleration exhaust groove 23 of the fixed cylinder 20 is formed on the outer circumference of the window frame 1 The second through hole 34 having the second engaging jaw 33 is formed. The first engaging protrusion 32 of the movable cylinder 30 is engaged with the engaging protrusion 24 of the fixed cylinder 20 to prevent the movable cylinder 30 from coming off, (23) and the acceleration exhaust groove (31) of the movable cylinder (30) communicate with each other.

[ Thus, before the operation of the buffering mechanism 10, only the interior of the fixed cylinder 20 is allowed to communicate with the outside of the reduced speed exhaust hole 22.

An elastic member 63 is provided between the stationary cylinder 20 and the pressing member 40. The elastic member 63 moves the moving cylinder 30 and the pressing member 40 from the stationary cylinder 20 To the direction of the arrow. The elastic member 63 is preferably composed of a compression coil spring.

The cushioning mechanism 10 of the present invention may further include a deceleration adjusting member 70 installed between the interior of the fixed cylinder 20 and the reduced speed exhaust hole 22 to adjust the size of the reduced speed exhaust hole 22, , And a length adjusting member (80) provided on an outer circumferential surface of the moving cylinder (30) on the side of the second through hole (34) for adjusting the length of the distal end of the moving cylinder (30).

The deceleration adjusting member 70 is made of a hard silicon material and can be kept airtight when it is embedded in the side wall of the stationary cylinder 20 , And an adjusting hole (71) communicating between the interior of the fixed cylinder (20) and the reduced speed exhaust hole (22) is formed. 5, the deceleration exhaust hole 22 is formed in a rectangular shape in the rotation direction of the deceleration control member 70, and the control hole 70 (see FIG. 5) of the deceleration control member 70, which is in contact with the deceleration exhaust hole 22, The exhaust-side opening is also formed in a rectangular shape. Therefore, by rotating the deceleration controlling member 70 in the forward and reverse directions as shown in FIGS. 7A and 7B, the area where the adjusting hole 71 and the reduced speed exhaust hole 22 coincide is changed So that the size of the deceleration exhaust hole 22 can be adjusted so that the degree of deceleration can be appropriately adjusted in consideration of the load of the window 3 when decelerating the closing speed of the window 3 as described later.

The length adjusting member 80 is composed of a fixing portion 81 fixed to the upper and lower outer circumferential surfaces of the moving cylinder 30 by screws and a connecting portion 82 connecting the both fixing portions 81, The fixing portion 81 is provided with a rectangular length-adjusting hole 83 through which a screw passes so as to adjust the length adjusting member 80 in the moving direction of the moving cylinder 30 as shown in Figs. 9A and 11, 30 can be adjusted. 9 (a), when the window 3 is closed as shown in FIG. 9 (a), the front end face of the length adjusting member 80, which is the outer face of the connecting portion 82, The length adjusting member 80 is preferably set at a position where the locker 4a of the lock assembly 4 can first contact the window frame 1 immediately before the locker 4a contacts the striker 2 of the window frame 1, It is possible to adjust the proximity distance a immediately before the locker 4a contacts the striker 2 of the window frame 1 as shown in Figures 9 (a) and 11 The proximity distance a immediately before the locker 4a and the striker 2 come into contact with each other in response to an error in installation of the window 3, the window frame 1, the automatic locking assembly 4, the striker 2, As shown in FIG. The proximity distance a is preferably 5 to 20 mm.

The operation of the present invention having such a configuration will be described with reference to FIGS. 8 to 10. FIG. 8 (a) and 8 (b), when the window 3 is closed, the buffer member 50 of the buffer mechanism 10 approaches the window frame 1 while the window 3 is close to the window frame 1 Thereby making contact with the window frame 1, whereby the impact noise can be primarily reduced by the buffer member 50 made of silicon.

9 (a), the cushioning member 50 and the urging member 40 are moved together while the elastic member 63 is compressed. By the movement of the urging member 40, The air is compressed. At this time, since the inside of the fixed cylinder 20 is in a state in which only the reduced speed exhaust hole 22 communicates with the outside and the airtight state is maintained by the first and second packings 61 and 62, the compressed air is discharged to the reduced speed exhaust hole 22 . Therefore, in the process of discharging the compressed air through the narrow deceleration exhaust hole 22, a resistance force is generated in the movement of the pressing member 40, and the closing speed of the window 3 is reduced by the resistance force, The window 3 is gradually closed during the moving distance range of the window.

7 (a) and 7 (b), the size of the reduction exhaust hole 22 is adjusted according to the rotation direction of the reduction control member 70, It is possible to increase the movement resistance of the pressing member 40 and to reduce the moving resistance of the pressing member 40 when the size of the reduction / exhaust hole 22 is largely adjusted, The deceleration of the closing speed can be appropriately adjusted in consideration of the load of the window 3.

9 (a), the movement of the pressing member 40 causes the window frame 1 to come into contact with the distal end surface of the length adjusting member 80 provided on the movable cylinder 30, The position of the striker 2 and the locker 4a is set at a position where the striker 2 first contacts the window frame 1 immediately before the striker 2 collides with the locker 4a, State.

9 (b), the pushing member 40 and the moving cylinder 30 are moved together, so that the striker 2 is moved together with the locker 4a However, since the closing speed of the window 3 is decelerated, the collision noise between the locker 4a and the striker 2 can be reduced secondarily.

At the same time, the first packing 61, which has been kept airtight between the moving cylinder 30 and the airtight holding surface 20a of the stationary cylinder 20 by the movement of the moving cylinder 30, And moves toward the surface 20b. The exhaust surface 20b is larger than the airtightness maintaining surface 20a so that a gap is formed between the first packing 61 and the exhaust surface 20b and the compressed air inside the stationary cylinder 20 flows through this gap The amount of air that escapes to the outside rapidly increases and the moving speed of the moving cylinder 30 and the pressing member 40 is increased by the amount of air flowing out to the outer circumferential surface of the movable cylinder 30 .

That is, after the locker 4a and the striker 2 collide, the closing speed of the window 3 increases, and the locker 4a is quickly locked to the striker 2 as shown in Fig. 10, The locking operation of the lock assembly 4 can be performed smoothly.

When the window 3 is moved in the opening direction with the window 3 closed, the pressing force of the moving cylinder 30, the pressing member 40 and the buffer member 50 is released as shown in Fig. 8 (a) The pressing member 40 and the buffer member 50 are restored by the elastic restoring force of the compressed elastic member 63 so that the same buffering function can be performed when the window 3 is closed .

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to be illustrative of the present invention and not to be construed as limiting the scope of the present invention as defined by the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
