Description

  The present invention relates to a joinery.

  Conventionally, when a shoji is opened and moved, for example, in a fitting such as a sliding window or a single-drawing window, the shovel of the shoji, and the hoist or vertical of other shoji (hereinafter also referred to as a counterpart hoist) Will be different. In view of this, there has been proposed a joinery in which a stopper mechanism is provided on a shoji that is opened and moved in order to prevent pinching of a finger when a downside and a counterpart downside are pulled apart.

  The stopper mechanism provided in such a shoji has a stopper portion and a switch portion, and these stopper portion and switch portion have an approach posture that has entered the inside of the shoji ridge and a projection that projects outward from the heel. It can be displaced between postures. In such a stopper mechanism, when the switch portion is in the approach posture, the stopper portion is in the projecting posture, while when the stopper portion is in the approach posture, the switch portion is in the projecting posture. Are interlinked. Further, in the stopper mechanism, the separation distance between the stopper portion and the switch portion is adjusted to be larger than the finding dimension of the counterpart vertical hook or the like.

  In the fitting having the stopper mechanism, when the shoji is moved open, the stopper portion in the projecting posture comes into contact with the other side vertical rod or the like, and the opening movement of the shoji is once restricted. Then, the switch portion is brought into a projecting posture by pressing the stopper portion into the approaching posture, and the contact state between the stopper portion and the other side vertical hook is released to move the shoji to open again. That is, in the above-mentioned fitting, when the shoji is moved to open, the stopper or switch portion in a projecting posture is brought into contact with the other side eaves etc. to temporarily restrict the opening movement of the shoji, and the other side eaves etc. The shoji is moved to open again so as to release the abutting state with the opponent vertical spade by manually pressing the stopper part or the switch part to be brought into the approaching posture.

  In this way, by temporarily restricting the opening movement of the shoji, the pinching of the shoji between the shovel of the shoji and the opponent's chisel is suppressed (for example, see Patent Document 1).

Japanese Patent No. 5129503

  By the way, in the joinery, one in which an opening / closing body is provided on a shoji that opens and closes is known. The opening / closing body opens and closes a shoji opening formed in the shoji. For example, when the shoji closes an opening to be opened / closed (hereinafter also referred to as a target opening), the opening / closing body opens the shoji opening. Therefore, ventilation can be allowed through such a shoji opening.

  However, there is the following problem in a joinery having a shoji provided with such an opening / closing body. In other words, if another shoji is moved while the shoji is closing the target opening and the opening / closing body is opening the shoji opening, if a part of the body passes through the shoji opening, There was a possibility that a part of the body might be sandwiched between the edge and other shoji.

  Therefore, it is conceivable to apply a stopper mechanism as proposed in Patent Document 1 described above. However, since the stopper mechanism or the switch part abuts against the other side vertical shaft etc. to temporarily restrict the opening movement of the shoji, the shoji mechanism is opened by a certain distance even if this stopper mechanism is applied. As a result, a part of the body may be sandwiched between the edge of the shoji opening and the other shoji.

  An object of this invention is to provide the fitting which can aim at the improvement of safety in view of the said situation.

  In order to achieve the above object, a joinery according to the present invention includes a shoji provided on the frame-like body so as to be opened and closed so as to open and close the first opening formed by the frame-like body, and a first door provided on the shoji. A door opening / closing body provided to the opening / closing movement of the shoji to open and close the opening, wherein the shoji closes the first opening, and the opening / closing body opens the second opening. In the state, a stopper is provided for holding the first opening closed.

  According to this invention, the stopper holds the state in which the first opening is closed when the shoji closes the first opening and the opening / closing body opens the second opening. It is possible to prevent a part of the body from being caught even if a part is passed.

  According to the present invention, in the joinery, the stopper is provided so as to be movable forward and backward through the stopper opening formed in the shoji, and the opening / closing body closes the second opening. On the other hand, when the opening / closing body opens the second opening, the posture moves forward to the outside against the biasing force of the biasing means. It is characterized by that.

  According to this invention, when the opening / closing body closes the second opening, the stopper is biased by the urging means and moves backward from the outside, while the opening / closing body opens the second opening. Since it is in a posture that has advanced to the outside against the urging force of the urging means, the first opening is closed so that it can come into contact with the components of the frame-like body or other shoji. Can be held.

  Further, in the joinery according to the present invention, when the stopper is rotatably provided so as to move forward and backward to the outside of the shoji along the expected direction of the shoji, and the opening / closing body closes the second opening In this state, the stopper opening is substantially closed while being biased by the urging means, and the opening and closing body closing the second opening is opened and brought into contact with the opening and closing body. In such a case, it is characterized in that the posture is rotated so as to move forward against the urging force of the urging means.

  According to the present invention, since the stopper is rotatably provided so as to move forward and backward along the expected direction of the shoji, there is no possibility of increasing the size of the stopper installation space. In addition, when the opening / closing body closes the second opening, the stopper is biased by the biasing means so as to retreat from the outside and closes the stopper opening, so that the inside is exposed through the stopper opening. The design can be improved. Further, when the opening / closing body that closes the second opening moves and comes into contact with the opening / closing body, the stopper is rotated so as to move outward against the urging force of the urging means. Therefore, it is possible to maintain a state in which the first opening is closed by being in contact with the components of the frame-like body or other shoji.

  Moreover, this invention is the said fitting, The said shoji performs opening and closing movement along the longitudinal direction of the upper frame which comprises the said frame-like body, The said opening and closing body performs opening and closing movement along an up-down direction It is characterized by being.

  According to this invention, even if a part of the body is passed through the second opening, the part of the body can be prevented from being pinched.

  According to the present invention, even if a part of the body is allowed to pass through the second opening, it is possible to prevent the part of the body from being pinched, so that it is possible to improve safety.
