Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a door lock device for a door that is designed to stably lock the bolt of a door that has convex finishing surfaces on both sides of the door shaft. It is something.

(Prior art) The applicant of this invention previously developed the device as a Buddhist hardware.
He proposed a structure in which guide hardware was attached to the door bar, which is currently in widespread use.

(Problem to be solved by invention) The hardware proposed above can be applied when the outside surface of the door shaft is flat (or when there is a convex finished surface on both sides of the door shaft, but it does not protrude from the outside surface). However, there was a problem in that it could not be used if the finished surfaces on both sides of the door shaft were protruding.

(Means for solving the problem) However, this invention solves the problem by interposing and fixing a backing plate with a thickness almost equal to the height of the convex finished surfaces on both sides of the door shaft between the door shaft surface and the bar hardware. Resolved the point.

That is, in this invention, in a Buddhist door having a convex finished surface on both sides of the door shaft, a contact plate having a thickness approximately equal to the height of the convex finished surface on both sides of the door shaft is brought into contact with the low wall surface on the outside of the door shaft, A locking device for a door with a doorway, which comprises stacking a guide member for a bar hardware on the relevant plate, fixing the plate and the guide member to the door shaft, and inserting a bar metal between the plate and the guide member. In addition, the guide member is a side-shaped bolt device for a door with a guide protrusion that fits loosely into the bolt groove at the lower center of the guide member, and the plate is a rectangular plate or a plate of equal thickness. This is a locking device for a Buddhist door, in which a pair of sides of a square plate are provided with a fitting groove for supporting the side walls of a guide member.

(Function) The lock device for the door of this invention stably slides to lock or unlock the lock even if the convex finished surfaces on both sides of the door shaft protrude.

(Example) Next, an example of this invention will be described as follows.

That is, the opening/closing side door shafts 3 of the doors 2, 2a of the Buddha hall 1,
Convex finished surfaces 4, 4a are formed protrudingly on both side edges of the door shaft 3, 3a, and rectangular contact plates 5, 5a having approximately the same thickness as the height of the convex finished surfaces 4, 4a are formed on the lower wall surfaces of the door shafts 3, 3a. are brought into contact with each other, and a guide hardware 6 is brought into contact with the abutment plate 5, thereby fixing the abutment plate 5 and the guide hardware 6 to the door shaft. A bar hardware 7 is inserted between the contact plate 5 and the guide hardware 6, and the guide strip 9 of the guide hardware 6 is loosely fitted into the groove 8 of the bar hardware 7, so that the bar hardware slides in the correct direction. I will guide you so that you can do it. 10 in the diagram
11 and 12 are decorative hardware, and 11 and 12 are edge hardware.

Next, as shown in FIGS. 5 and 6, fitting grooves 14 and 14a may be provided on both opposing edges of the contact plate 13 to fit and support both side walls 6a and 6b of the guide hardware 6. With such a structure, the contact plate 13 and the guide hardware 6 are integrated, and the bar metal can be reliably guided.

The backing plate and the guide hardware in the above embodiments do not necessarily have to be made of metal, but may also be made of synthetic resin, for example.

(Effects of the invention) In other words, according to this invention, a contact plate having a thickness that is approximately the same as the height of the convex finished surfaces on both sides of the door shaft is interposed between the guide member and the door shaft wall surface, so that both sides of the door shaft Even in the case of a door shaft with a convex finished surface on the edge, there is an effect that the bar hardware can be slid accurately and smoothly in the correct posture.
