Japanese Patent No. 2640917

However, in the conventional crescent lock described in Patent Document 1, a screw cover is required for each of at least two screws for fixing the pedestal. Therefore, the pedestal position is adjusted by attaching and detaching or loosening the screws. In this case, it is necessary to slide the screw covers at two locations, so that the workability is poor and the number of parts increases.
Furthermore, in conventional crescent locks, pedestals, sickle locks, knobs, etc. are made of metal because strength is required, whereas screw covers are often made of resin, and the texture of the pedestal and screw cover is In addition to being different, since the sickle lock part is engaged with the lock holder, it cannot be painted and becomes a metal color, and the color of the sickle lock cannot be matched with the pedestal and screw cover, so there is a problem that the appearance design is inferior. .

  An object of the present invention is to provide a locking device and a fitting capable of easily operating a screw for fixing a base of a crescent lock, and capable of reducing the number of parts and improving the appearance design.

The locking device of the present invention is a fitting that is engaged by a crescent lock that is fixed to an indoor summoning portion and a lock rest that is fixed to an outdoor summing portion in a joinery having a sliding door that can be opened and closed. The crescent lock includes a pedestal fixed to the indoor summoning unit with a screw, and an unlocking position that is supported by the pedestal and engaged with the lock receiving portion. A sickle lock that is pivotably provided between positions, an operation part for turning the sickle lock, and a cover part that covers the base and the sickle lock in the unlocked position. The cover portion is configured to be rotatable between a first position that covers the pedestal and a second position that exposes the fixing screw of the pedestal to enable screw operation, and the crescent lock is A secondary cover located on the opposite side of the cover from the base and sickle lock A gap is formed between the sub-cover part and the cover part, through which a connecting part that extends from the sickle lock and is connected to the operation part is inserted. The sub-cover portion is supported by the sub-cover portion so as to be rotatable between the first position and the second position, and an intermediate member along the inside of the gap is provided between the cover portion and the sub-cover portion. It is attached to a pedestal .

Here, the first position is a closed position where the cover portion faces the pedestal and covers the side surface thereof, and the fixing screw is not operable, and is a position where the cover portion is disposed in the normal use state of the joinery. . In addition, the second position is an open position where at least a fixing part that is a part of the pedestal is exposed and the fixing screw can be operated, and the cover part is moved when the crescent lock is attached / detached or the position is adjusted. It is a position.
According to the present invention described above, the crescent lock is configured to have the cover portion that covers the base and the sickle lock in the unlocked position, and thus it is necessary to individually cover a plurality of screw positions as in a conventional screw cover. Instead, the entire cover can be covered with one cover portion located at the first position, and the number of parts can be reduced. Further, the plurality of screws can be easily operated simply by rotating the cover portion to the second position, and the workability of attaching and adjusting the crescent lock can be improved.
In addition, since the crescent is almost entirely covered with the cover part, the pedestal and sickle lock cannot be seen from the appearance, and even if the material and paint color of these members and the cover part are different, the difference in texture and color can be seen. Therefore, the appearance of the crescent lock can be determined by the texture and color of the cover part, and the design can be improved. Moreover, the designability improvement as a fitting can also be aimed at because the member with a complicated shape like a sickle lock becomes invisible.

Under the present circumstances, by extending the connection part from a sickle lock through the clearance gap between the cover part in a crescent lock , and a sub cover part, a sickle lock and a base become much less visible, and design nature can be improved further. That is, the gap dimension between the cover part and the sub-cover part may be set to a minimum dimension that allows the coupling part to be inserted, and with this configuration, the inside of the cover part can hardly be seen through the gap. Can be.
Furthermore, since the cover part is pivotally supported by the sub-cover part, it is possible to easily operate the screw by simply opening the cover part to the second position side, further improving the workability of attaching and adjusting the crescent lock. Can be improved.
Furthermore, by providing the intermediate member inside the gap between the cover portion and the sub cover portion, the sickle lock and the pedestal can be hidden by the intermediate member when looking inside through the gap.

Further, in the lock device of the present invention, the cover portion, the sub-cover, the intermediate member and the operating section is preferably formed from a respective resin material.
According to such a configuration, the cover part, the sub cover part, and the operation part that are exposed on the outer surface of the intermediate member and the crescent lock are formed of the resin material, and if this resin material is made common, it can be seen from the outside. Almost all the characteristic parts can be unified with the same texture and color, and the design of the crescent lock can be greatly improved.

Furthermore, in the locking device of the present invention, it is preferable that the cover portion is locked to at least one of the pedestal, the sub cover portion, and the intermediate member in the first position.
According to such a configuration, the cover portion can be prevented from inadvertently moving (opening) in the first position, that is, the cover portion being closed, and the cover portion is released only when the screw operation is necessary. Can be opened to the second position.

On the other hand, the joinery of the present invention includes at least one shoji that can be slid open / closed in the left / right or up / down direction. It is a joinery that closes in an overlapping manner, and is characterized in that it can be locked by any of the locking devices described above.
According to such a joinery, the number of parts of the crescent lock can be reduced, and the workability of attaching and adjusting the crescent lock can be improved, as in the effect of the above-described lock device. Furthermore, the appearance design of the crescent lock can be improved, and the design of the joinery can be improved by matching the color of the cover part to the joinery.
Here, the joinery of the present invention may be a sliding window, a sliding window, a sash window such as a raising / lowering window, or a sliding door or a sliding door. If the joinery is a sliding window or sliding door, it may have a pair (two) of shojis, or it may have three or more shojis (for example, a three-story window or Doors, four-story windows and doors). In addition, when the joinery is a sliding window or sliding door, the shoji (moving shoji and door) sash (summing bowl) and the fixed parts fixed to the building or frame outside or indoors. The shoji, sleeve wall, vertical bone, etc. overlap in the expected direction and the shoji closes, that is, the shoji of other shoji is made up of the shoji material of the fixed shoji, and the edge of the sleeve wall, the vertical bone, etc. The summoning part should just be comprised.
