Description

[Technical field] The present invention relates to a seat for a heart lock.

[Background technology]

As shown in Japanese Patent Application Laid-Open No. 62-50573, a conventional padlock seat has a receiving hole into which a locking portion of a guard rod engages and disengages, and the locking portion moves in a vertically elongated shape as the door opens. However, with this conventional seat, when the door is opened to the maximum opening angle that can be obtained within the range restricted by the watch rod, when the door is released, The door was automatically closed by the closing force such as checking, and it could not be held in the open position, which was very inconvenient.

[Purpose of device]

The present invention is for solving the above-mentioned conventional problems,
An object of the present invention is to provide a seat for a guard rod that can arbitrarily hold the door in an opened state in the vicinity of the maximum opening angle when the guard rod operates and the door is opened.

[Disclosure of device]

The present invention proposed to achieve the above-mentioned object relates to a seat of a safety lock in which the opening angle of the door is regulated by the safety guard, and in particular, a receiving hole for engaging and disengaging the locking portion of the safety guard. And a longitudinally elongated guide hole in which the locking portion moves according to opening of the door, when the locking portion of the precautions rod is located near the end of the guide hole, the locking portion or its shaft The present invention is characterized in that an engaging portion that prevents return movement in the receiving hole direction is provided, and a restricting member that restricts the locking portion or the shaft thereof so as not to move and engage with the engaging portion.

〔Example〕

A description will be given based on the embodiment illustrated below. FIG. 1 and FIG. 2 show the usage state of the seat (1) of the locking pad according to the present invention, in which the locking rod (10) of the locking pin (12) attached to the door is
The locking part (8) provided on the free end side of the guard rod (11) was made to project in the cylinder (13) or thumb turn (14), etc., and was engaged in the receiving hole (2) of the seat (1). After that, the state in which the door is opened is shown. As the door is opened, the guard rod (10) rotates about its pivot (11), and the shaft (9) of the locking portion (8) of the guard rod (10) has a vertically elongated guide hole (3). Move upwards along. Then, the shaft (9) of the locking portion (8) comes into contact with the terminal end portion of the guide hole (3) of the seat (1), and the further opening of the door is restricted by the guard rod (10).

(4) is an engaging portion provided on the door closing side near the end of the guide hole (3) of the seat (1), and the shaft (9) of the locking portion (8) of the guard rod (10) is engaged. To do.

Reference numeral (5) is a restriction member that is slidably held in the seat (1) in the vertical direction. The regulating member (5) is provided with a knob (6) for sliding operation by hand, and the knob (6) is exposed to the outside through a hole (1a) provided in the seat (1). . Further, the restricting member (5) is internally provided with a click motion steel ball (5b) and a spring (5a), and the holes (7a) and (7b) provided in the box holder (7) of the seat are made of steel. The regulating member (5) is stably held at the position corresponding to the sphere (5b).

[Operation of the present invention]

 The operation of the present invention will be described.

With the door closed, project the locking rod (10) and receive the locking part (8) on the seat (1)
When the door is opened by locking it in the receiving hole (2) of Fig. 1 (indicated by the dashed line in Fig. 1), the locking part (8) moves in the direction of arrow (a) in Fig. 1,
(9) contacts the end of the receiving hole (2). When the door is further opened, the guard rod (10) rotates about the shaft (11) as a fulcrum, the locking part (8) moves upward in the guide hole (3), and the end part of the guide hole (3). The door, and further opening of the door is restricted by the vigilance rod (10).

Next, when the door is released, the door tries to be closed by the force of the closer (not shown), but as shown in FIG. 1, the shaft (9) of the locking portion (8) of the watch rod (10). Engages with the engaging part (4) provided on the closing side of the end of the guide hole (3) of the seat (1), and the shaft (9) of the locking part (8) cannot move downward. Therefore, the door is held in this open state.

To close the door, push (pull) the door in the opening direction from the engaged state shown in FIG. 1 to move the guard rod (10) to the door side, that is, the lock pad (1).
It will be pulled to the 2) side and the locking part (8) and shaft (9)
Is disengaged from the engaging portion (4) of the seat and is positioned as shown in FIG. In this state (while pushing the door in the opening direction), slide the regulating member (5) upward (see FIG. 3).
When the left end of (5) comes into contact with the engaging part (8) and the hand is released from the door, the closing part of the closer causes the engaging part (8) to move toward the engaging part (4) as shown in FIG. Try to move to the
The movement in the direction of the engaging portion (4) is blocked by (5), and the movement moves downward. That is, the locking part (8) and its shaft (9) are seated (1).
The guide hole (3) is moved downward and the door is closed.

If the regulating member (5) is held in the state shown in Fig. 3,
When the guard rod (10) is actuated to open the door, the locking part (8) or its shaft (9) is not held by the engaging part, so if you release your hand from the door, the door will automatically close by the closing force of the closer. Close the door.

(5a), (5b) are springs and steel balls installed inside the regulating member (5), the steel balls fit into the holes (7a), (7b) provided in the box support (7),
It functions to stably hold the regulating member (5) in the state shown in FIGS. 1 and 3.

[Other modifications]

In the embodiment of the present invention, when the door is held in the open state, the holding portion (4) connected to the guide hole (3) of the seat is provided with the locking portion.
The shaft (9) of (8) was engaged and held, but
Form a holding part inside (1) or fix the holding member,
The locking portion (8) may be engaged with this and held.

Also, depending on the regulating member (5), the locking portion (8) or its shaft
As a means for restricting (9) from engaging with the holding part (4), there is shown a structure in which the restriction member (5) prevents the locking part (8) from moving in the engaging direction to the holding part. But the shaft of the locking part (8)
The movement of (9) may be blocked.

In addition, the shape of the holding portion is arbitrary, and the structure of the regulating member (5) and the structure of the member for stably holding the regulating member are also arbitrary.

[Effect of the present invention]

According to the seat of the body lock according to the present invention, when the opening angle of the door is regulated and opened by the guide rod, the door is at about the maximum opening angle position, that is, the locking portion of the guide hole of the seat. In the vicinity of the terminal part, the locking part or its shaft engages with the engaging part provided on the seat, so that the door can be opened while the door is open for ventilation, etc. It is convenient because it can be held at.

Moreover, it is convenient because it is possible to arbitrarily select whether the door is held in the open state or not by operating the regulating member.

Furthermore, when closing the door from the open state, it is necessary to push (pull) the door once in the opening direction and then operate the regulating member by hand, so the door should close at the moment when the regulating member is activated. Since it is not, there is no accident such as a finger or hand being caught between the caution rod and the seat, and it is safe.
