Description

[Detailed description of the invention] This invention relates to a lower structure used for doors, single casement windows, double casement windows (double casement windows), etc. (hereinafter referred to as doors etc.).

Conventionally, a lock lever equipped with a roller is attached to the lower frame, and the door body has a built-in lock lever that moves up and down with a bundle, and when the door is closed, the lock lever advances, and the roller moves the door body toward the indoor side. A structure is known in which the container is attracted to the container and is locked in the container.

However, since doors and the like are generally supported on a cantilever, the load may be applied to the free end side, causing the door to sag.

If the door, etc. is closed in this state, the door, etc. will hit the receiver and be damaged, so it is necessary to close the door, etc. while lifting it slightly, and then lock the lock lever.

This invention allows the door body to climb onto the rollers without any trouble and close the door body even if the door body is slightly tilted down due to the presence of the inclined surface of the falling stop metal fitting. Since the door body is drawn toward the lower frame side through the door and pressed against the sealing material, it is possible to improve the air/water tightness when the door is closed.

Next, an embodiment of this invention shown in the drawings will be described.

In the figure, reference numeral 1 denotes a door body forming a stile 1a including a pair of outer panels 2 and 3 facing each other at appropriate intervals.

(As mentioned above, this invention can be applied to all doors, windows, etc. installed in the openings of buildings, but for convenience of explanation, we will explain the case of doors.

) Stile 1a on the non-hinged side of the door body 1
A case 4 is attached inside, and a square shaft 5 is supported within this case 4.

A lock piece 6 is fixed to the square shaft 5, and a part of the lock piece 6 projects out of the door body 1 as the bundle 7 fixed to the square shaft 5 rotates. Then, it is engaged with a locking portion of a structure (not shown) constituting the fixed side (in the case of a single-door door) or a mating door body (in the case of a double-door door).

a pair of links 10.11 each pivoted at diametrically opposed positions with respect to the square shaft 5 with pins 8 and 9, respectively;
The other end of the link 10 is connected to an upper lock rod 13 via a suitable interlocking system connected by a pin 12, while the link 11 is connected to a lower lock rod 15 via a pin 14.

The pivot position of the pins 8 and 9 is such that when the lock piece 6 is in the unlocked position (the imaginary line position in FIG. 5), the square shaft 5 is
The two ends of the tension spring 16 are respectively fixed between the pin 12a and the case 4 so that they face each other in a substantially horizontal plane.

That is, the link 10 is constantly pulled to facilitate rotation of the bundle 7 when the lock piece 6 is unlocked.

The upper and lower locking rods 13, 15 are connected to the upper frame 17. The ends 13' and 15' of the receivers formed in the lower frame 18 are inserted into the metal fittings 19 and 20 by rotating the bundle 7, but at this time, the lower lock lever is inserted into the metal fittings 19 and 20. In part of 15,
A groove 21 formed in the longitudinal direction is provided, and a locking member 22 is provided slidably at the position of the groove 21 in a direction substantially orthogonal to the longitudinal direction of the lock rod 15. This locking member 22 through which the spring 23
Since the tip is made to protrude into the middle of the door body, it is repelled by the material.

In other words, while the door body 1 is closed, the fixed side (in the case of a single opening) or the door body on the opposite side (in the case of a double opening)
A locking member 22 is abutted against the locking member 22 .
As a result of being pushed in against the force of the spring 23, it separates from the groove 21 and the lock 15 is free to move, but the door body 1
When the bundle 7 is operated in the direction to release the lock piece 6 and the door body 1 is opened, the lock member 22 is pushed out by the spring 23, and the lock member 22 is in the retracted position of the lock rod 15. After being locked in the groove 21, the bundle 7 becomes unrotatable, and the protruding operation of the lock rods 13, 15 and the lock piece 6 is prevented.

A roller 24 that guides the end portion 15' of the lower lock rod 15 is supported in the metal fitting 20 of the receiver into which the end portion 15' of the lower lock rod 15 enters, and the engagement with the roller 24 is smoothly performed. Furthermore, in order to subsequently pull the door body 1 as a whole toward the lower frame 18 and bring it into close contact with the sealing material 25, a beveled surface 26 is formed on the end portion 15'.

Note that the receiver 27 is a drain hole provided in the metal fitting 20.

A drop stop metal fitting 28 is attached to the lower end surface of the door body 1, and the lower surface of this fall stop metal fitting 28 is used to facilitate engagement with the roller 24 and to compensate for the downward movement of the free edge side of the door body 1. The sloped surface 29 is formed with this purpose in mind, and by providing this sloped surface 29, even if the free edge side is slightly downward due to the weight of the door body 1 when the door body 1 is opened, the door body 1 can be opened without any problem. This makes it possible for the rollers 24 to ride on the rollers 24.

Next, the structure for preventing rotation of the lock piece 6 will be explained. When the lock is transported, when the lock is stored in the door body 1, or when the lock is detached from the door body 1 due to a malfunction, the lock piece 6 of the lock is inadvertently rotated. A screw 30 is screwed into the side of the lock piece 6 to prevent it from moving.

On the other hand, on the case 4 side, there is a hole 32 that allows the screw 30 to be loosened with a screwdriver or the like, and in which the head 31 of the screw 30 is locked. If the lock piece 6 is locked, the movement of the lock piece 6 is prevented, so that it is extremely easy to store and remove the lock from the door body 1, and it also becomes easy to transport.

It goes without saying that this screw 30 is screwed into the lock piece 6 again when the lock is used.

In the above configuration, a lower stop metal fitting 28 is attached to the lower end surface of the door body 1, and this lower stop metal fitting 28
Since an inclined surface 29 is formed on the lower surface of the door, even if the free edge side of the door body 1 is slightly downward when opened,
When the door body 1 is swung toward the lower frame 18 at the closing part,
The sloped surface 29 rides on the roller 24 and the height of the door body 1 which has tended to fall can be corrected, and in this way, the door body 1 is always returned to the correct position when closing. It is something that can be done.
