Description

[Technical Field] The present invention relates to an improvement of a seat of a heart lock.

[Background technology]

Since the mounting screw is exposed on the seat of the conventional guard lock, when the guard rod acts to regulate the opening angle of the door,
There was a danger that a screwdriver would be inserted through the open gap, the mounting screws for the seat would be removed, and illegally entered.

[Purpose of device]

The present invention is for solving the above-mentioned conventional problems,
When the guard rod acts and the opening angle of the door is regulated, it cannot be illegally removed from the open gap,
It is an object of the present invention to provide a seat for a caution tablet having excellent security.

[Disclosure of device]

The present invention proposed to achieve the above object relates to an improvement of a seat of a safety lock which is configured so that the opening angle of the door is regulated by the safety guard, and more particularly, to a receiving lock for disengaging the locking portion of the safety guard. A guard rod that holds the shutter movably in a seat having a hole, a vertically elongated guide hole in which the locking portion moves according to opening of the door, and a mounting hole, and moves the guide hole portion when the door is opened, or It is characterized in that the locking portion of the guard ring pushes the shutter so that the shutter shields at least one mounting screw.

〔Example〕

 Below, it demonstrates based on the Example shown in figure.

(First Embodiment) FIGS. 1 to 4 show a seat according to a first embodiment of the present invention.
It shows (1) and its usage.

(14) is a safety lock attached to the door (B), which is a cylinder (13)
Alternatively, by operating the thumb turn (12), the watch ring (7) is made to appear and disappear. (8) is a locking portion integrally formed on the free end side of the guard rod (7), and (9) is a shaft having a smaller diameter than the locking portion (8).

(1) is a seat that is attached to the frame (A) with mounting screws (4) and (4), and is connected to the receiving hole (2) where the locking part (8) engages and disengages. A vertically elongated guide hole (3) is provided. This guide hole (3)
Has a width smaller than the diameter of the engaging portion (8), and is provided in such a size that the axis of the engaging portion (8) can move.

(6) is a shutter, one end of which is pivotally attached (5) and is rotatably held by a seat, and the other end is a guide hole (3) of the seat (1).
I want this to happen. The pivoting method is as shown in FIG.
It may be pivotally attached (5) by a rivet pin (5a), and its method is arbitrary.

Next, the operation will be described.

With the door completely closed, the cylinder (13) of the watch rod (14)
Alternatively, the thumb turn (12) is operated to project the watch ring (7), and the locking portion (8) of the watch ring (7) is engaged with the receiving hole (2) of the seat (1). When the door is opened in this state, the shaft (9) of the locking part (8) moves in the receiving hole (2) in the door opening direction (left direction in Fig. 1), and the shaft
(9) contacts the end of the receiving hole (2). If you open the door further,
The guard rod (7) pivots about its pivot (10), and the lock (8) has its shaft (9) moved upward along the guide hole (3) of the seat (1), The opening angle of the door increases with the movement. Then, the shaft (9) of the locking portion stops at the end of the guide hole (3),
The door is restricted by the vigilance rod (7) and cannot be opened any further. (The state where the vigilance rod is working) (See FIG. 2 and FIG. 3) By the way, as described above, the shaft (9) of the locking portion (8) is seated (1).
When moving upward in the guide hole (3) of the above, while moving the shutter (6) pivotally attached (5) to the seat (1) as described above, the shutter (6) moves to the second position. It is pushed to the state shown in the figure. In this state, even if you try to remove the mounting screw (4) of the catch by inserting a screwdriver through the open gap of the door, it cannot be removed because it is blocked by the shutter (6), so it is illegal. Can't break in.

In addition, since the mounting screw (4) is removed, even if the shutter (6) is moved, its clockwise rotation is blocked by the shaft (9) of the locking portion (8). The rotation of the is blocked by the door stop (A ') of the frame (A). (Note that as a method of preventing the counterclockwise rotation, a stopper (1a) may be formed on the seat (1) without depending on the door stopper.) Also, the shutter (6) is shown in FIG. Pull it toward you,
Even if it is attempted to be removed from the seat (1), it is safe because it is protected by the terminal end of the watch rod (7). In addition, the stopper
If it is also protected by (1a), it will be even safer.

A shutter (6) may be provided so that both the mounting screws (4) and (4) are shielded by the shutter (6), but as in the first embodiment of the present invention, at least one mounting screw
If the (4) is shielded, the catch (1) cannot be removed.

(Modification of the First Embodiment) FIGS. 5 to 8 are modifications of the first embodiment of the present invention. FIG. 5 shows a shutter (6) pivotally attached to a seat (1). The mounting screws (4) and (4) are always shielded, and the at least one mounting screw (4) is shielded by turning when the watch ring is actuated.

FIG. 6 shows that the shutter (6) is rotated in the opposite direction (clockwise) by the shaft (9) of the locking portion to shield the mounting screw (4) during the action of the vigilance rod. It is a thing. In this case, the shutter (6) can be rotated without forming a slope on the free end of the shutter (6) pushed by the shaft (9).

7 and 8 show the seat (1) mounted with a single mounting screw (4). The shutter (6) has a spring (6a) for returning.
Shows what is caused to act.

(Second Embodiment) FIGS. 9 and 10 show a second embodiment.
The shutter (6) is slidably held on the seat (1), and is pushed (raised upward) by the shaft (9) when acting on the guard rod so that the upper mounting screw (4) is shielded. It was done.

That is, the shutter (6) is slidably held by fitting the bent piece (6b) into the cutout hole (1b) of the seat (1), and the shutter (6) has the seat (6b). A hole (6c) that is almost the same as the receiving hole (2) of 1) is provided, and the end portion of the hole (6c) is caused by the shaft (9) of the locking part (8) of the caution rod when the precaution ring is operated. Is pulled upward (pushed), and the shutter (6) slides upward.

(Modification of Second Embodiment) FIGS. 11 and 12 show a modification of the second embodiment, in which the shutter (6) can slide in the left-right direction with respect to the seat (1). It is held on the lock part when the watch rod is operated.
It is pushed by the shaft (9) of (8) and is slid to the right in FIG. 11 by the action of the inclined surface 6d which is the passive portion, so that the mounting screw (4) is shielded. Reference numeral (20) is a spring provided between the shutter (6) and the seat (1) for returning the shutter (6).

(Other Modifications, etc.) In the above embodiments, all the shutters (6) have the locking portions (8).
Although the shaft (9) is used for pushing, the shutter (6) may be pushed by the locking portion (8) or the watch ring (7).

In addition, since the opening angle of the door is the maximum when the locking part of the precautionary rod moves in the guide hole of the seat when the locking part is located at the terminal end of the guide hole, the shutter is opened in this state. It is desirable to shield the mounting screws.

[Effect of device]

According to the seat of the body lock according to the present invention, the guide of the seat is actuated during the action of the watch rod (when the door is opened with the engaging portion of the guide rod engaged in the receiving hole of the seat). Locking part that moves the hole,
Alternatively, the shutter that is movably held on the seat is pushed by the shaft of the locking part or the guard rod, and the shutter shields the mounting screw of the seat, so that the driver can open from the gap of the door opened within the regulation range. It is not possible to illegally remove the strike plate by inserting. That is, it is possible to provide a seat for a caution tablet that is very excellent in terms of crime prevention.
