Description

  The present invention relates to an opening device such as a sash, and more particularly to an opening device in which the position of a locking device can be easily adjusted.

In general, an opening device such as a sash has a locking device in a summoning ridge portion. For example, in the opening device described in Patent Document 1, a mechanism main body portion (hereinafter referred to as a “key body”) for operating locking / unlocking is provided on the inner summoning bowl of the inner shoji, so There is a reception (hereinafter referred to as “key reception”) in the summon bowl. Further, the key holder is fixed to the indoor side surface of the outside summoning bowl by screws or the like from the indoor side.
Japanese Patent Laid-Open No. 2001-82019

  When the opening device is installed, the key body and the key holder are finely adjusted after the outer and inner shojis are fitted into the frame. At this time, with respect to the key body provided in the inner summoning bowl, since the installation portion of the key body is exposed to the indoor side, the position of the key body can be easily adjusted by adjusting a screw or the like. .

  The cross-sectional view which looked at the locking state of the opening part apparatus from the upper direction in FIG. 8a was shown. Further, FIG. 8b shows a cross-sectional view of the state in which the opening device is unlocked, and the inner limb 20 is moved to the left side of FIG. 8b and the outer limb 30 is moved to the right side of FIG. 8b. Thus, in order to adjust the position of the key holder 60, the inner and outer shojis 20 and 30 are moved as shown in FIG. In some cases, this state is sometimes referred to as a “running state”), and the position of the key holder 60 has to be adjusted.

  Moreover, in recent years, the area of the opening part of an opening part apparatus has become large, and, therefore, the inner shoji 20 and the outer shoji 30 have increased in weight. Therefore, as shown in the locked state in FIG. 9a and the unlocked state in FIG. 9b, a handle 90 is provided on the vertical shaft of the opening device to facilitate opening and closing of the heavy weight shoji. In addition, when the shoji is opened, the outer shoji 30 may be provided with a stopper 95 in order to prevent the inner summon basket 22 from hitting the handle.

  However, when the handle 90 or the stopper 95 is provided on the vertical shaft as described above, the movement of the shoji is hindered as shown in FIG. 9b, and the shoji cannot be put into a state of being pushed as shown in FIG. 8b. . Therefore, in order to adjust the position of the key holder 60, as shown in FIG. 9c, it is necessary to remove the inner shoji 20 from the frame. In this case, since the heavy weight shoji is removed, the workability is poor. Met. Further, in order to finely adjust the position of the key receiver 60, the attaching and removing operations are repeated such that the inner shoji 20 is further attached, the position with respect to the key body is confirmed, and the position is further removed and adjusted. It was necessary and the workability was very poor.

  In particular, in the case of a crescent lock, by locking, the outer summoning basket 32 is attracted to the inner summoning bowl 22, and the outer summoning bowl 32 and the inner summoning bowl 22 are separated to the left and right, whereby the airtightness of the opening device is improved. Therefore, it is necessary to accurately adjust the position of the key holder 60, and a means capable of adjusting with good workability has been demanded.

  Then, this invention makes it a subject to provide the opening part apparatus which has a locking device which can adjust the position of the key holder 60 easily.

  The present invention will be described below. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment.
