Description

用於拉門的鎖具Locks for sliding doors

本發明關於一種鎖具，尤指一種用於拉門的鎖具者。The present invention relates to a lock, especially a lock used for sliding doors.

現有拉門，電動或手動者，大抵包含有一軌道及至少一可沿該軌道移動的門板，又為使現有拉門能進行鎖制，避免其他人任意進入，於現有門板上會另行設置鎖具，以鎖制拉門，如德國第10 2016 217 664號專利案（以下簡稱為參考案）所示者，參考案的鎖具主要具有一鎖定裝置及一驅動器，該鎖定裝置具有一閂鎖及一自動恢復力使閂鎖移動至一解鎖位置，且該閂鎖係通過該驅動器致動的方向克服自動恢復力，而處於可操作的鎖定位置，如此當閂鎖位於鎖定位置時，即可鎖制該拉門，以避免其他人任意開啟拉門。Existing sliding doors, either electric or manual, generally include a track and at least one door panel that can move along the track. In order to lock the existing sliding door and prevent others from entering at will, a separate lock will be installed on the existing door panel. To lock the sliding door, as shown in the German Patent No. 10 2016 217 664 (hereinafter referred to as the reference), the lock of the reference mainly has a locking device and a driver, and the locking device has a latch and an automatic The restoring force moves the latch to an unlocked position, and the latch overcomes the automatic restoring force through the actuation direction of the driver, and is in an operable locking position, so that when the latch is in the locked position, the latch can be locked. Sliding the door to prevent others from opening the sliding door arbitrarily.

然而，如現有參考案的拉門鎖具結構，在結構及使用上具有下列問題：However, the sliding door lock structure of the existing reference case has the following problems in structure and use:

１．參考案之結構複雜，且參考案的鎖定機構係組裝在滑輪組上，當鎖定機構位於鎖定位置而同時去拉動門板時，因旋轉應力靠近滑輪組，如此容易導致滾輪脫離軌道，導致門板無法順利移動，另外參考案的鎖閂與鎖臂間係形成斜面，故當門板受力拉動時，會沿其斜面產生一向上的分力，而使滑輪組向上抬動，如此更易造成滑輪脫離軌道。1. The structure of the reference case is complicated, and the locking mechanism of the reference case is assembled on the pulley block. When the locking mechanism is in the locked position and the door panel is pulled at the same time, the rotation stress is close to the pulley block, which easily causes the rollers to leave the track, causing the door panel to fail to move smoothly. In addition, the lock bolt and the lock arm of the reference case form an inclined plane, so when the door panel is pulled by force, an upward component force will be generated along the inclined plane, and the pulley block will be lifted upward, which makes it easier for the pulley to leave the track.

２．參考案的閂鎖主要係利用重力作用下落來提供自動恢復力而移動至解鎖位置，但若其鎖具有因生鏽或異物卡住等其他因素，容易造成其內部結構的卡制，導致其閂鎖無法利用重力而恢復至解鎖位置，如此當遭遇緊急狀況時，將令拉門無法順利被開啟，進而造成拉門使用上安全性的疑慮與問題。2. The latch of the reference case mainly uses gravity to fall to provide automatic restoring force and move to the unlocked position. However, if the lock has other factors such as rust or foreign matter jamming, it is easy to cause the internal structure of the lock, resulting in the latch The lock cannot be restored to the unlocked position by gravity, so when an emergency occurs, the sliding door cannot be opened smoothly, which will cause doubts and problems in the safety of the sliding door.

３．當發生緊急狀況，導致室內的使用者無法自行由室內開啟拉門時，參考案的鎖具無法由他人自拉門外部進行緊急解鎖的動作，因此現有拉門的鎖具在使用上仍有其不足之處，需作改進。3. When an emergency situation occurs and the indoor users cannot open the sliding door by themselves, the lock of the reference case cannot be unlocked by others from the outside of the sliding door. Therefore, the existing sliding door locks still have shortcomings in use. Place, need to be improved.

藉此，請配合參看圖3，當未啟動驅動單元36時，卡擋件34因回復單元38所提供回復力量的推抵，而令卡擋件34的第二端縮入於基座32內部，而位於解鎖位置，如此，門板20可順利地沿軌道10移動，以開啟或關閉拉門，當欲鎖制拉門時，請配合參看圖4及圖5，則啟動驅動單元36，使活動桿362推抵卡擋件34的第一端，而令卡擋件34相對基座32樞轉，使卡擋件34的第二端伸出基座32，此時，可讓卡擋件34的第二端抵靠於門板20，如門板20之端緣，或一固定於門板20上的鎖制塊22，如此當有人欲移動門板20時，藉由卡擋件34與門板20或鎖制塊22的相互抵靠，及驅動單元36對卡擋件34所提供的限止作用，可提供該欲移動門板20的抵制力量，即可止擋門板20相對軌道10移動，而讓拉門位於鎖制狀態，無法任意地開啟或關閉拉門，此時，卡擋件34的第二端形成有一可與門板20端緣或鎖制塊22相接觸的鎖制面，且該鎖制面與拉門的移動方向可呈90度垂直，且與拉門間可呈平面接觸、曲面接觸或點接觸等，如此當鎖具位於鎖制位置，而有人用力拉動門板時，除因本發明的鎖制塊22係設置於門板20上而遠離滑輪組，故門板受力的旋轉應力亦遠離滑輪組，如此可避免滑輪組因受力而脫離軌道10外，亦同時可因拉門受力的方向與鎖制面呈90度，而避免向上分力的產生，亦可進一步確保滑輪組不會脫離軌道10。Therefore, please refer to FIG. 3. When the driving unit 36 is not activated, the blocking member 34 is pushed by the restoring force provided by the restoring unit 38, and the second end of the blocking member 34 is retracted inside the base 32 , And is in the unlocked position. In this way, the door panel 20 can smoothly move along the track 10 to open or close the sliding door. The rod 362 pushes the first end of the blocking member 34 to pivot the blocking member 34 relative to the base 32 so that the second end of the blocking member 34 extends out of the base 32. At this time, the blocking member 34 can be allowed to The second end of the abutting against the door panel 20, such as the end edge of the door panel 20, or a locking block 22 fixed on the door panel 20, so when someone wants to move the door panel 20, the stopper 34 and the door panel 20 or lock The mutual abutment of the blocks 22 and the restricting effect provided by the driving unit 36 on the stopper 34 can provide the resisting force of the door panel 20 to be moved, which can stop the door panel 20 from moving relative to the rail 10, and the sliding door can be positioned at In the locked state, the sliding door cannot be opened or closed arbitrarily. At this time, the second end of the stopper 34 is formed with a locking surface that can contact the end edge of the door panel 20 or the locking block 22, and the locking surface and The moving direction of the sliding door can be 90 degrees perpendicular, and it can be in plane contact, curved contact or point contact with the sliding door, so that when the lock is in the locked position and someone pulls the door forcefully, except for the locking block of the present invention The 22 system is arranged on the door panel 20 away from the pulley block, so the rotation stress of the door panel is also far away from the pulley block. This prevents the pulley block from leaving the track 10 due to the force. At the same time, the direction of the sliding door force and the locking surface 90 degrees, and avoid the generation of upward component force, which can further ensure that the pulley block will not deviate from the track 10.

當欲解鎖拉門時，令驅動單元36反向移動活動桿362，使活動桿362遠離推抵卡擋件34第一端的位置，如此可利用回復單元38所產生的回復力量來反向推抵卡擋件34的第一端，而令卡擋件34的第二端縮入基座32內而回到解鎖位置，如此可讓門板20順利地沿軌道10移動，而開啟或關閉拉門。When the sliding door is to be unlocked, the driving unit 36 is made to move the movable rod 362 in the reverse direction, so that the movable rod 362 is moved away from the position of the first end of the blocking member 34, so that the restoring force generated by the restoring unit 38 can be used to push in the reverse direction. Abut the first end of the blocking member 34, and the second end of the blocking member 34 is retracted into the base 32 to return to the unlocked position, so that the door panel 20 can smoothly move along the rail 10 to open or close the sliding door .

藉由本發明的鎖具30，可適當地簡化鎖具30整體結構的複雜度，降低整體的生產成本，且利用卡擋件34之第二端來抵靠門板20或門板20上的鎖制塊22，如此可令鎖具與鎖制塊22的抵靠位置遠離門板20上的滾輪，如此當本發明的鎖具位於鎖制位置，而拉動門板20時，可避免門板20上的滾輪因受力而脫進軌道10，可提昇拉門使用時結構穩定性。With the lock 30 of the present invention, the overall structure complexity of the lock 30 can be appropriately simplified, the overall production cost can be reduced, and the second end of the stopper 34 is used to abut the door panel 20 or the locking block 22 on the door panel 20, In this way, the abutment position between the lock and the locking block 22 can be far away from the rollers on the door panel 20, so that when the lock of the present invention is in the locked position and the door panel 20 is pulled, the rollers on the door panel 20 can be prevented from coming off due to force. The track 10 can improve the structural stability of the sliding door when in use.

再則，因本發明的卡擋件34係透過回復單元38所提供的回復力量而由鎖制位置移動至解鎖位置，如此可避免卡擋件34因生鏽及異物等因素而發生卡制等不良現象，可令卡擋件34能順利地移動至解鎖位置，防止因緊急狀況而無法開啟拉門的情況發生，以提昇拉門整體使用之安全性。Furthermore, because the blocking member 34 of the present invention is moved from the locked position to the unlocked position by the restoring force provided by the restoring unit 38, the blocking member 34 can be prevented from being blocked due to factors such as rust and foreign objects. The undesirable phenomenon can enable the stopper 34 to smoothly move to the unlocked position, prevent the situation that the sliding door cannot be opened due to emergency situations, and improve the safety of the overall use of the sliding door.

其次，請配合參看圖6，當發生緊急狀況，使用者無法由內部開啟拉門時，如室內人員昏倒無法自行解鎖拉門等狀況，可由他人自外部以一薄形物體，如***等，由基座10與門板20間的縫隙推動卡擋件34的第二端，而將卡擋件34的第二端推入於基座32內部，使卡擋件34的第二端離開鎖制位置，以便讓門板20能沿軌道10移動，以開啟拉門，來排除內部的緊急狀況，以提高拉門使用之安全性。Secondly, please refer to Figure 6. When an emergency occurs and the user cannot open the sliding door from the inside, such as a person in the room fainted and unable to unlock the sliding door by himself, a thin object, such as a credit card, can be used by others from the outside. The gap between the base 10 and the door panel 20 pushes the second end of the stopper 34, and pushes the second end of the stopper 34 into the base 32, so that the second end of the stopper 34 leaves the locking position , So that the door panel 20 can move along the track 10 to open the sliding door, to eliminate the internal emergency situation, and to improve the safety of the sliding door.
