[Industrial applications]

 The present invention locks the doors of hanging cabinets, cabinets, etc. to securely hold the doors so that the contents will not be pushed open and damaged due to vibrations such as an earthquake during closing. More particularly, the present invention relates to a locking tool in which a holding member automatically returns to a locked position only by a movement when closing a door.

[0002]

[Prior art]

 Examples of conventional furniture opening stoppers include spring catches and magnet catches described in JP-B-30-15546, JP-B-31-16268, JP-B-35-32198, and the like. However, these are methods that are simply attached to the door tips of the doors and temporarily fixed to the doors, and did not completely lock the doors in the open state.

[0003] Also, it was usual to use an automatic door-closing cabinet hinge as disclosed in Japanese Utility Model Publication No. 37-19724, but since the hinge only urges the door to the cabinet. In the event of an earthquake, etc., there was no ability to prevent the contents stored in the cabinet from being pushed out by vibration and opening the door from the inside to drop and damage it.

In order to make up for the above-mentioned drawbacks, there are Japanese Utility Model Publication No. 58-50052 and Japanese Utility Model Publication No. 58-50053, which are attached to the bottom plate of the cabinet and are located below the assembly portion of the double doors that are closed. By pressing the tip in the direction perpendicular to the door opening direction to prevent the door from opening, it is possible to prevent the contents of the closet from pushing the door open from the inside and dropping it. Met.

In the above-mentioned two inventions, one holding member presses both doors to hold the closed doors. When engaging the locking tool, be sure to hold both doors with the other hand. The locking part of the member had to be flipped up, but in Japanese Utility Model Publication No. 59-26065, the locking part is divided into two parts so that each locking part operates individually, and A rotating leg is provided in the same body, and a rod that interlocks with the rotation of the holding member and the opening and closing of the door is installed.When the door is closed, the rod pushes the rotating leg and the holding member automatically closes the door. It is formed so that the double doors can be opened and closed individually by rotating it up to.

[0006]

[Problems to be solved by the device]

 In the configuration described in the above publication, the holding member is divided into two pieces, each holding member is operated separately, and the turning leg is provided in the same body on the barrel, and the holding member is turned. By providing a rod that is linked to the opening and closing of the door, when the door is closed, the rod pushes the turning leg, and the holding member automatically turns to the closing position to lock the door. There is.

However, when the locking portion is rotated when the door is opened, the rotation leg protruding in the same body as the shaft cylinder of the holding member operates in conjunction with the locking portion, and the rotation leg moves to the rod. By pushing the shaft end, the pushing part of the rod is pushed out and the door is pushed to open the door.However, since the pushing force of the pushing part of the rod only slightly lifts the door from the cabinet, it is suspended. Doors such as cabinets made it difficult to open, and I needed a picture and a handle.

Further, even when the door is closed, the push spring constantly pushes the rod toward the partition wall, and therefore the biasing force that pushes the push portion into the front wall of the casing causes the turning leg to return to its original holding position. However, due to the urging force of the cam that is pressed against the barrel via the push spring that is inserted into the end of the casing, the mutual force balance between the rod and the rotating leg is maintained. It is arranged so as to lean and only prevents the locking part from rotating, so the locking part will rotate with the door open due to external vibration or pressure, and the original holding position Sometimes, the door was left unclosed, and it did not function as a locking device.

[0009]

[Means for Solving the Invention]

 The door locking device according to the present invention includes a casing directly or indirectly attached to a cabinet body, a side-surface substantially U-shaped holding member pivotally mounted in the casing, and a fitting member fitted to the casing. It consists of a rod inserted and a cam that is constantly pressed against a notch provided on the end surface of the shaft of the holding member via a push spring that is also inserted into the end of the casing. The shaft cylinder of the holding member, which is movably mounted in the casing, is provided with a rotating leg protruding from the shaft cylinder, and the pushing portion is arranged near the front wall of the casing, and the shaft of the shaft cylinder side. The shaft end of the rod, which is constantly urged toward the front wall by the push spring inserted into the shaft, is slidably inserted into the casing as opposed to the rotating leg, and is inserted into the notch in the end face of the shaft cylinder. Is a push spring fitted to one end of the casing. Ri, cams are those pressed constantly holding member is forced held in the holding position location in the casing.

When the locking portion of the holding member is rotated to open the door, the pushing portion of the rod is pushed out from the front wall of the casing by the urging force of the push bar, pushing the inside of the door to automatically move the door. The door opens, but at this time, the cam rides over the notch and is in constant pressure contact with the barrel, so the holding member operates without rapid rotation, but at this time the upper end of the locking part of the holding member The idling angle is set so that the pivot leg does not push the shaft end of the rod until it is separated from the door.

Further, when the door is closed, the pushing portion is pushed into the front wall of the casing, the pivot end of the barrel is pushed by the shaft end of the rod, the barrel is rotated, and the pushing part is provided on the end face of the barrel. The cutout part is returned to the position facing the cam, and the cam is inserted into the cutout part.The pressing force of the cam at this time causes the holding member to repel and rotate to the original holding position. The locking part of the holding member is formed so as to automatically abut and lock the door so that it cannot be opened.

[0012]

[Action]

 According to the above method, the pivot leg is provided on the barrel of the holding member, and the rod interlocking with the rotation of the locking portion and the opening / closing movement of the door is arranged. The pushing part of the rod is pushed out vigorously by the urging force of the push spring inserted in the shaft part of the, and the inside of the door is pushed to push the pushing part by opening the inside of the door and automatically opening the door. The shaft end of the rod causes the rotation leg of the holding member to rotate, and the cam is elastically fitted by the pressing force of the push spring that is inserted into one end of the casing in the notch of the shaft cylinder, so that the cam is held The member was rotated so that the door was automatically abutted and locked so that it could not be opened, but the locking part was inserted so that the end of the closed door was at a right angle to the opening direction of the door. By pressing in the direction to prevent the door from opening, storage items such as storage shelves can be opened. To fall damaged pushes open from the inside, locking member of the door is effectively prevented can be obtained.
