的門框’使其密接的機構，過去已有例如日本實開昭 =ΓΓ公報（專利文獻13及日本特公平6-847㈣公報 (專^文獻2)所記载的楔型構件及誘導轉子受到廣泛的使 用。該密接機構是將此模型構件安裝於防火門，並將誘導 轉子固疋於建物側，藉由使楔型構件相對於誘導轉子移 動’而將防火門向相反側的門框推壓。 316229 5 1295335 [專利文獻1]曰本實開昭5 第3圖 ⑽93866就公報，第2圖、

而且，本發明之第2目的在於提供一種可用較小的力 進行門扇之開閉的拉門推壓裝置。 316229 1295335 (用以解決課題之手段） 本發明之上述第1目的可藉由第1樣態之閉鎖裝置的 發明而達成，該拉門是藉由門扇滑輪而懸掛支持，並且且 有會自動關閉之自閉_，而在關閉位置時，係將拉門^ 門扇面的緣部配置成與門框相對向的拉門用之閉鎖裝置， /、中”有用來凋節拉門之關閉速度的調速機構；以及用 來將拉：的緣部在關閉位置向門框推屡的推壓機構’·在關 閉位置前方的預定位置之前，調速機構會使拉門的關閉速 度減速為比湘自_構的_速度還慢，並且從預定位 置朝向關閉位置加快。 —根據此第1樣態之發明，由於到拉門之關閉位置前的 預定位置之前，是使拉門的關閉速度減速，因此拉門不容 易與往來的人碰撞。另一方面，到達預定位置時，由於是 朝向關閉位置加快，因此即使因推壓機構而對拉門施以朝 開啟方向作用的阻力，仍會以加快的速度關閉，所以拉門 會順著關閉的力量而完全_。因此，由於拉門是配置在 與門框相對向的位置’並在此位置因推壓機構使拉門向Η 框推壓，故可確保密封狀態。此外，使拉門之關閉速度開 始加快的預定位置及加快速度’按照與所使用的推壓裝置 的關係來決定’只要可使拉門完全關閉即可。根據第1樣 態：發明’在拉門為防火門的情況中，火苗及濃煙就不容 易机入而在屬於其他用途的拉門的情況中，則可隔斷拉 門的丽後兩側’而防止不同溫度的外部氣體流入。 另外，在第1樣態之發明實施形態中，調速裝置具有： 7 316229 1295335 藉由門扇滑輪的旋轉而動作，並且用 轉的發電機· # n戶、、Λ认 Ρ制門扇岣輪之旋 至二： 骨輪的旋轉在拉門開啟期間不-傳遠 =達齡與發電機之輸_的電阻^向運 度在預定位m / 以使拉門的關閉速

的絲將拉門向門框推壓的㈣機構，在關 速度減速:預位’調速機構可使拉門的關閉 使拉門在關閉位;;可==成無制 猎甶自閉機構而關閉但不會減速。 預匕第上樣態的發明中，由於在拉門之關閉位置前的 K置之耵，拉門的關閉速度會減速，因此拉門不容易 =來的人石並撞。另一方面’在預定位置時，調速裝置是 H制動狀態’拉門在關閉位置之前，可藉由自閉機構 不會減速。因此，拉門的關閉速度是朝向關閉位 316229 8 1295335 置加快，即使對拉門施以藉由推壓機構朝開啟方向作用的 :力，仍會以加快的速度„，所以拉門會順著關閉的力 量而完全關閉。因此，由於拉門是配置在與門框相對向的 位置，並且在此位置藉由推壓機構將拉門向門框推壓，故 :確保密封狀態。此外，使拉門的關閉速度開始加快的預 定位置，可按照與所使用的推壓裴置的關係決定，即可使 拉門完全關閉。第2樣態之發明巾，在拉門為防火門的情 下’火苗及濃煙就不容易竄入，而在其他用途的拉門的 月兄下貝J可斷拉門的前後兩側，而防止不 部氣體流入。 ！ U卜 弟2樣態之發明實施形態中，言周速裝置具有 ，：輪的旋轉而動作，並且用來抑制門扇滑 :機；使W的旋轉在拉門開啟㈣不會傳達至發1 電 ^ ’而在拉⑽閉期間傳達至發電機的單向運動傳達機 至所輸出連接的電阻;可將電阻的電阻值降低 所希:值’使拉門的關閉速度在㈣位置之前減速至

Field of the Invention The present invention relates to a locking device used for a sliding door supported by a door leaf pulley and having a self-closing mechanism that automatically closes, and more specifically A locking device, for example, which can completely lock a sliding door type fire door. [Prior Art] In order to prevent the burning in the event of a fire, (4) there will be a fire door in the exit passage. The fire door has: the door leaf buckle is normally opened in the open state. The buckle is only released when it is in an emergency. _ The time-open fire protection ^'2 and the normally closed state are manually opened when passing: fire protection Doors. No matter which kind of fire door is equipped with a self-closing mechanism to be automatically closed. 曰 From η fires in recent years, because the chance of burning smoke of smouldering smoke is still ancient, Tian + ^, 午 汉It is asked by 4, so the 'fire dam is not only used to prevent the smog accident prevention function. Therefore, it is not enough to close the door: it is also necessary to prevent the smoke from leaking from the periphery of the fire door. In the past, it has been known that the door frame of the fire door is closely connected to the door frame around the opening of the passage to make it close to each other. In the past, for example, the Japanese version of the Japanese translation (Patent Document 13 and the Japanese Special Fair 6-847 (4) bulletin (specialized) ^ The wedge member and the induction rotor described in Document 2) are widely used. The adhesion mechanism is to mount the model member to the fire door, and the induction rotor is fixed to the building side by making the wedge member relative to Induced rotor In the case of the fire door, the fire door is pushed to the door frame on the opposite side. 316229 5 1295335 [Patent Document 1] 曰本实开昭5 3rd figure (10) 93866 is the bulletin, 2nd drawing, [Patent Document 2] 3, 7th, 10th, and #2, and [invention] (the object to be solved by the invention), the transverse member of Patent Document 1 and the method of inducing the rotor induce the V rotor to sometimes be wedged. The structure of the door stops at the middle of the material of the #-piece, and returns in the direction of the opening of the Guang Dynasty without being completely closed. -: The king is closed, and the smoke and the flame will peep into it. It is difficult to set the inclination angle. Tilt: 2 =: 2 The ink pushing force will become smaller. If the tilt angle is increased, the wedge member and the child will stop when they abut each other, so that the fire door cannot change the position s, and the other 2 forcefully closes the door leaf, the door leaf Will be strongly pushed to the door frame, the opening of the day will occur due to overweight and the law is set in the first month of October, because it is usually open, only in an emergency, only closed, ', so there will be nothing Convenient, but in the case of f closed fire doors ^ ordinary people When they want to pass, they must open the door leaf by themselves, but the opening and closing is very heavy, so it is not ideal. ' Yu, the first object of the present invention is to provide a locking device for the sliding door which can completely close the sliding door. A second object of the present invention is to provide a sliding door pressing device that can open and close a door leaf with a small force. 316229 1295335 (Means for Solving the Problem) The above first object of the present invention can be achieved by the first aspect. According to the invention of the locking device, the sliding door is suspended and supported by the door leaf pulley, and has a self-closing _ that automatically closes, and in the closed position, the edge of the sliding door is arranged to be the same as the door frame. The locking device for the opposite sliding door, /, "there is a speed governing mechanism for closing the closing speed of the sliding door; and the pressing mechanism for pushing the edge of the pulling: to the door frame in the closed position." Before the predetermined position in front of the closed position, the speed governing mechanism decelerates the closing speed of the sliding door to be slower than the speed of the sliding door, and accelerates from the predetermined position toward the closed position. According to the invention of the first aspect, since the closing speed of the sliding door is decelerated before the predetermined position before the closing position of the sliding door, the sliding door cannot easily collide with the passing person. On the other hand, when the predetermined position is reached, since it is accelerated toward the closed position, even if the sliding mechanism acts on the sliding door in the opening direction due to the pressing mechanism, it will be closed at an accelerated speed, so the sliding door will be closed. The power is completely _. Therefore, since the sliding door is disposed at a position opposite to the door frame, and the pressing mechanism pushes the sliding door toward the frame, the sealing state can be ensured. Further, the predetermined position and the acceleration speed at which the closing speed of the sliding door starts to be increased are determined in accordance with the relationship with the pressing device used, as long as the sliding door can be completely closed. According to the first aspect: the invention 'in the case where the sliding door is a fire door, the flame and the thick smoke are not easy to enter, and in the case of a sliding door belonging to other uses, the two sides of the sliding door can be cut off' It prevents the inflow of external gases at different temperatures. Further, in the first embodiment of the invention, the speed governing device has: 7 316229 1295335, which is operated by the rotation of the door leaf pulley, and is used by the generator of the turn, the door, the wheel, and the wheel. Rotate to two: The rotation of the bone wheel does not pass during the opening of the sliding door = the resistance of the age and the output of the generator _ the resistance is at the predetermined position m / so that the closing speed of the sliding door - in the pre-turn position Then, the speed is decelerated to the desired speed value so that the speed: value change mechanism is accelerated from the predetermined position to the closed position. In this embodiment, the speed of the speed is closed by the use of the heart. Moreover, the above-mentioned first object of the present invention can achieve the "sliding support", which is automatically closed by the portal, the privately-held brother, and the automatic closing of the door. The closing mechanism, when in the closed position, is pulled to oppose the door frame, the locking device for the sliding door has a speed adjusting mechanism for the closing speed of the sliding door; and when the wire pushes the sliding door toward the door frame (4) The mechanism, deceleration in the closing speed: the pre-position 'speed governing mechanism can make the sliding door close so that the sliding door is in the closing position;; can be == into the self-closing mechanism without hunting, but will not slow down. In the invention of the first state, the closing speed of the sliding door is decelerated due to the K setting before the closing position of the sliding door, so that the sliding door is not easy to hit. On the other hand, when the vehicle is in the predetermined position, the governor is in the H-braking state. The door can be decelerated by the self-closing mechanism before the door is closed. Therefore, the closing speed of the sliding door is set to be faster toward the closing position 316229 8 1295335, even if the sliding door is applied by the pressing mechanism in the opening direction: the force will still be at an accelerated speed, so the sliding door will follow The closing force is completely closed. Therefore, since the sliding door is disposed at a position opposite to the door frame, and the sliding door pushes the sliding door toward the door frame at this position, the sealing state is ensured. The predetermined position at which the closing speed starts to be accelerated can be determined according to the relationship with the pressing device used, so that the sliding door can be completely closed. The second aspect of the invention towel, in the case that the sliding door is a fire door, the flame And the smoke is not easy to break in, but in the other use of the sliding door of the moon brother, the shell J can break the front and rear sides of the sliding door, and prevent no gas from flowing in. ! U Budi 2 state of the invention embodiment , the peripheral speed device has: the rotation of the wheel and the action, and is used to suppress the door leaf slip: the machine; the rotation of the W is not turned on when the sliding door is opened (4) and is not transmitted to the hair 1 and is transmitted to the hair during the pull (10) closing period. One-way motion of the motor to the machine Output the connected resistance; the resistance value of the resistor can be lowered: the value 'decels the closing speed of the sliding door before the (four) position to the motion: speed: the resistance changing mechanism; and the predetermined position before the predetermined position The mechanism to the closed position is set to 0FF. Doors =, in the first and second aspects of the invention, the towel has a guide that will be supported by the top two, and in contrast to the guide:::: ::The central control will install the door leaf pulley in the guide (4): the state of pulling, and the installation tool of the door leaf pulley and the holding shaft and the mutual tool (4) are connected in a rotatable state by extending toward the door of the sliding door.

The slidable 54^family belt 55 is sequentially conveyed to the large diameter brake/fan pulley 4, and the force is applied to the rotation of the door leaf pulley 24. It is stated that the fire door 16 is intended to accelerate along the inclined guide 6, and the rotation of the door leaf pulley 24 is affected by this braking force; the closing speed of 16 is slowed down. Next, if the circuit is used for the day and the month, the i-th variable resistor 64 is turned on by switching the switch 68 at the initial position. The fire prevention 16^fan pulley 24 is rotated along the inclined guide rail 6 to start closing' and travels at the first closing speed decelerated by the month 1 variable resistor 64. When the fireproof door is moved from the open position to the closed position and the front end of the door reaches the predetermined position ^, the changeover switch 68 on the first variable resistor 64 side is turned off by the switch switching unit 72, and the second variable resistor 66 side is turned off. The changeover switch 7A is turned ON, the first variable resistor 64 is rendered inactive, and the second variable resistor 66 is made effective. Thereby, a larger current is required for the generator 56, so that the rotation of the rotation of the shaft 316229 24 1295335 is reduced, the fire door!

At the same time, the positions of the steering brackets 82 and the pressing brackets are the same as those of the first embodiment, and the tops of the upper frame 12 and the second upper frame 14 are the same. In this case, the rear end of the door and the front end of the door are completely heavy, so the longitudinal sectional view is the same as that of the first 316229 25 1295335. It is also described in the case of the mounting position:: two crankshafts, but the situation. That is, the fire can not be set up - if the same crankshaft is in contact with the rear end side of the door; =; the crankshaft attached to the front end side of the door, the crankshaft of the front end side of the door protrudes, and the front end side of the door is changed. The steering can be used to avoid the use of the bracket 8 "(4). At this time, the position of the female f and the pusher of the factory are the same as those of the crankshaft of the present embodiment. The pillars are raised to look at the same parts.

Because of the interference problem in the (4) example, even if it is installed at the fire door 16 position, there is no The problem is to briefly describe the action of the pusher in the third modification, that is, the crankshaft on the side of the steering bracket 90 is provided. When the rotating bodies of the long rods 37 of the rods 86 are abutting, this action is transmitted to the two crankshafts by the freely rotatable coupling plate 88 to the other: 316229 26 1295335 square crankshaft 86 The rotating body 89 of the lever % is engaged with the truss % for pressing, and the door frame 4 of the fire door w 2 is pressed. The same applies to the pressing device of the fourth modification shown in Fig. 13 . In the pressing device according to the fourth modification, only one crankshaft 94 is provided on the upper portion of the fire prevention n 16. The pressing device shown in the fifth @ is a rotating body provided on the short rod side in the crank cup 94. 4〇, and in the rotating body%, the center of the rotating shaft is provided with a freely rotatable rotating body supporting member: (4) The plate 96' is respectively provided with a rotating body % at both ends of the pushing and reverse 96. The push plate 96 extends from the pivot shaft attached to the short rod toward the closing direction and the opening direction of the fire door, and the rotating body % is rotatably mounted at the front end portion thereof.

The opening of the brothers 14 to f 16 is the pushing of the locking device of this embodiment. Other embodiments of the press-fitting are shown in Fig. 14 which is a view showing the upper portion of the door as shown in Fig. 2, and Figs. 15 and 16 are plan views of the pushing device of the other embodiment. Fig. 14 to Fig. 16. The pressing device 1〇4 of the drawing has: a pushing guide 106 attached to the fire door 16; and a pushing roller 1 attached to the second upper frame 14 and being engaged with the pressing member 106 of the pusher 3] 6229 27 1295335 〇 8. _ The retracting roller 108 protrudes, and has a parallel surface in which the disc extends from the side of the yoke toward the push-and-close direction of the yoke. The yoke is formed in parallel with the plate-shaped member made of metal. The guide member 1〇6 is the front end side portion of the door from the door of the fire door 16;;=;7 is to make the plate member in the roller _(10), at the end portion of the door 222: laterally push * 曲. 1 knife (1) The common opening and closing direction extends in parallel and the bending side is referred to the fifteenth and fifth views, as shown in Fig. 15. As shown in Fig. 15, in the fire door 16, the full-closed position of the human door 16 is described for the action. Previously, the front end of the door of the fire door 16 is about to reach the closed position, and the fire door 8.0 will be engaged with the inclined surface of the dust guide 106. As the guide m moves toward the closed position (15th) As indicated by the arrow in the figure, the pusher (10) will move relative to the push roller 108, and the (four) face will cross the parallel face and snap on the push roller (10) while hunting. The fire door 16 will be from the second. The door frame 4 side is far away. When the fireproof (10) is combined with the 2 full closing position, as shown in Fig. 16, push the roller to the ground ^ "4 pieces of 1G6 parallel faces" And the fire door 16 is pressed against the surface of the door frame 4. The locking device of the present embodiment is such that the pressing device starts to move before the fire door 16 is reached, and the (four) before the shirt is completely closed. By the pressing device 18, the movement resistance of the fire door 16 is generated, 316229 28 1295335, but due to the speed adjusting device 30, the closing position is closed from the predetermined position pj, and the speed is closed at an accelerated speed, so the fire door 16 will be closed along the door. The force is better than the movement resistance and is closed. Therefore, since the pressing device 18 is actuated in a state in which the oyster king is completely closed, the fire door 16 and the door frame 4 can be completely blocked. The present invention is not limited to the above. The embodiment is intended to be modified within the scope of the invention as set forth in the appended claims. For example, the above embodiment is directed to the application of the locking device i to the sliding door fire. The case of the door is described, but it is not limited to the fire door, and may be applied to a sliding door for other purposes. Moreover, the above embodiment describes the case where the locking device ι is applied to the single pull J. The same can be applied to the double sliding door. In the case of the double sliding door, the sealing material is formed only at the bonding portion of the two, or the cross-sectional shape of the door of the square sliding door is formed into a c-shape. The damper structure can be accommodated in the front end portion of the door of the other sliding door. For example, the pressing device 18 can be mounted on the two fire doors with the X σ portion being symmetric about the center. The fan fire door is pressed against the door frame 4 and the gap between the door and the door frame 4 is eliminated. The main embodiment is that the above embodiment is applied to the case of the normally closed fire door sill, and the above-mentioned closing can also be used. The setting 1 is applied to a normally open fire door that is closed by the fastening mechanism at a position where the fire door 16 is opened, and the buckle mechanism is released in the event of a fire.
