Description

[Detailed description of the invention] [Industrial application field] This invention relates to a lock hiding device for a swinging door.

[Prior art]

In a hinged door, a latch bolt is provided at the end of the opening/closing side of the door so as to be able to move in and out toward the vertical frame or child door.

[Problems to be solved by this idea]

The latch bolt is formed in a locking hole formed in the vertical frame, but since there is a gap between the hinged door and the vertical frame or child door, the latch bolt can be seen from the outside of the room. It did not make an impression, and its appearance looked bad.

For this purpose, as shown in FIG. 6, it was necessary to hide the latch bolt by fixing a concealing piece c protruding in opposite directions to the outdoor side surface of the swing door a, the window frame, or the child door b.

[Means for solving problems]

The lock hiding device for a swinging door according to this invention has a protrusion that protrudes toward the vertical frame or child door from a part of the widthwise indoor side of the end of the left and right side of the swinging door on which the lock is attached, and continues in the vertical direction. A vertically continuous stepped portion is formed on the outside of the width direction of the end portion, and a latch bolt is protruded from the vertical frame or child door side of the protruding portion, and By facing the indoor side surface of the protrusion that protrudes from and continues in the vertical direction, the outdoor side surface of the protrusion of the swing door faces,
The above problem is solved by locating the latch bolt on the indoor side of the vertical frame or the protrusion of the child door.

〔Example〕

This invention will be explained in detail below based on an embodiment shown in the drawings.

In the figure, 1 is a frame body, upper and lower horizontal frames 2,
2. It is framed in a rectangular shape by left and right vertical frames 3, 3.

4 is a parent door which is a swinging door, and 5 is a child door, both of which have upper and lower horizontal stiles 6, 6, left and right vertical stiles 7, 7, which are assembled into a rectangular shape, and horizontally spanned by a horizontal frame 8. . A vertical bar 9 is spanned over the main door 4 in the vertical direction midway between the left and right sides.

Panels 10,
10 is bonded to the adhesive. Panel 10,1
A plurality of rectangular small openings 11 are suitably bored in the opening.

A gasket 12 is attached to opposite side surfaces of the panels 10 at the outer periphery of the small opening 11 of the panels 10, 10. A glass plate 13 is held between the gaskets 12, 12.

The main door 4 and the child door 5 are attached adjacent to the frame 1 by hinges 22. A lock 14 is attached to the upper and lower middle of the main door 4 on the child door 5 side.

A protrusion 15 is formed on a part of the widthwise indoor side of the end of the main door 4 on the child door 5 side, protruding toward the child door 5 side and continuing in the vertical direction. Therefore, a step portion 16 that is continuous in the vertical direction is formed on the outside of the room in the width direction of the end portion.

A latch bolt 17 of the lock 14 is projected from the protrusion 15 on the side of the child door 5.

A protrusion 18 that is continuous in the vertical direction is protruded from the main door 4 side of the child door 5, and the outdoor side surface of the protrusion 15 of the main door 4 and the indoor side surface of the protrusion 18 face each other.
In the embodiment, the protrusion 18 is formed in the shape of a protrusion, and the protrusion 18 is formed in the shape of a protrusion.
A lip groove 19 is formed on the interior side surface of the case 8. A rubber cushioning material 20 is attached to this lip groove 19 so that the protrusion 15 of the main door 4 can come into contact with it.

A lock receiving hole 21 that opens toward the main door 4 is provided on the indoor side of the projection 18, and the latch bolt 17 can be locked therein.

When the main door 4 is closed in a hinged door having the above configuration, the outdoor side surface of the protruding portion 15 is connected to the child door 5.
In order to face the indoor side surface of the protrusion 18, the protrusion 1
The latch bolt 17 that protrudes further toward the child door 5 than the latch bolt 5 is located on the indoor side of the protrusion 18.

Therefore, only the gap between the step 16 of the main door 4 and the protrusion 18 of the child door 5 is visible from the outside of the room, but the latch bolt 17 is not visible, giving a clean impression and improving the external appearance.

The above example is about the case where the main door 4 and the child door 5 are attached to the frame 1, but when only the swing door 4 is attached to the frame 1, the swing door 4 is attached to the vertical frame 3.
What is necessary is to form a protrusion toward.

[Effect of idea]

This idea forms a protrusion on a part of the widthwise indoor side of the end of the hinged door on which the lock is attached, and makes the latch bolt protrude from the vertical frame or child door side of the protrusion.
The protrusion of the swing door faces the indoor side of the protrusion of the vertical frame or the child door that protrudes toward the swing door, and the latch bolt is positioned on the indoor side of the protrusion of the vertical frame or the child door, so the latch bolt is attached to the protrusion. Twisted and hidden;
From the outside of the room, only the gap between the stepped part of the main door and the protrusion of the child door can be seen, giving a clean impression and improving the external appearance.
