Description

[Detailed description of the invention] <Technical field> This invention relates to the strike of a sickle lock, and involves hooking a sickle piece to the main body of the sickle lock, which has a sickle piece, among the sickle locks used in the joining parts of sliding doors, etc. It's about a strike.

<Prior art> The above-mentioned sickle lock is provided with a sickle piece that can be freely entered and exited by turning a key, etc. on one sliding door in the joining part of a pair of sliding doors, and the other sliding door is provided with a sickle piece that can be freely entered and exited by turning a key etc. A strike having a hooking hole that can be hooked is attached to the piece, and the locking effect is achieved by hooking the sickle piece and the hooking hole to each other.

And the pair of sliding doors to which the sickle locks are attached are
They are installed so that they run with a certain gap between them on opposite sides. Therefore, the sickle lock must be equipped in such a way that the sickle piece of the sickle lock body and the engagement hole of the strike are securely engaged, taking into account the gap created on the opposing surfaces of the above-mentioned sliding doors. .

In order to do this, the sickle piece should be firmly pressed against the engagement hole of the strike so that it is firmly engaged, but when installing a sickle lock on a sliding door, etc. , a certain amount of play is required, and if the sliding door is used for a long period of time, the installation may become loose and the positional relationship between the hooking hole of the sickle piece and the strike may become misaligned. Therefore, in practice, it is extremely difficult to accurately position the sickle piece and the engagement hole of the strike so that they are always firmly engaged.

Furthermore, if the engagement condition is too tight, there is a problem that when the sickle piece is rotated to perform the latching operation, the sickle piece may get caught on the edge of the engagement hole, or the sickle piece cannot be smoothly inserted into the engagement hole. In particular, if the positions of the hooking hole and the sickle piece are misaligned, it may become impossible to hook them. Therefore, when the sickle piece is engaged, it is better to provide a certain amount of clearance between the sickle piece and the engagement hole, which is contrary to the above-mentioned tight engagement action between the sickle piece and the engagement hole. There were also demands.

<Purpose> Therefore, the purpose of this invention is to solve the above-mentioned problems of the prior art, and to make it possible to smoothly engage the sickle pieces when they are engaged, and to ensure that they are engaged securely and firmly once engaged. The purpose is to provide strikes with excellent usability.

<Structure> In order to achieve the above object, a window for inserting the sickle piece is formed in the strike for hooking the sickle piece, which is installed in the sickle lock body so as to be freely removable.
