Description

次に、上記の課題を解決するための手段を、実施の形態に対応する図面を参照して説明する。
本発明の請求項１記載の開動助勢機構は、扉１３の木口１３ｃ側より進退自在なラッチ３３を有し、該ラッチ３３の進出状態の保持及び該保持状態の解除を行う連動機構３５を備え、前記扉１３の表裏面に対して接離方向に移動自在とされて設けられる把手１１を、前記扉１３の開く方向に押す或いは引くことにより、前記連動機構３５を介して前記ラッチ３３を後退或いは後退を許容させるとともに前記扉１３の開放が行われる開動助勢機構において、
前記扉１３の木口１３ｃ側より突出自在な突出杆３７と、
前記把手１１の押し引き動作に従動して一方向に回転し前記連動機構３５による前記ラッチ３３の進出状態の保持を解除するとともに前記突出杆３７を突出させるカム板３１と、
前記扉１３の閉鎖時における該扉１３の木口１３ｃ側に対向する建物側枠体７５に配設され、前記突出杆３７の突出時に当接し、該突出杆３７の突出方向に対して略直交する前記扉１３の開放方向へ、前記突出杆３７の突出とともに前記扉１３を揺動させる当接部７３と、
を具備することを特徴とする。 Next, means for solving the above problems will be described with reference to the drawings corresponding to the embodiments.
The opening assisting mechanism according to claim 1 of the present invention includes a latch 33 that can be moved forward and backward from the wooden end 13c side of the door 13, and includes an interlocking mechanism 35 that holds the latch 33 in the advanced state and releases the held state. The latch 33 is retracted via the interlocking mechanism 35 by pushing or pulling the handle 11 provided so as to be movable toward and away from the front and back surfaces of the door 13 in the opening direction of the door 13. Alternatively, in the opening assist mechanism that allows the backward movement and the door 13 is opened,
A projecting rod 37 that can project freely from the end 13c of the door 13;
A cam plate 31 that rotates in one direction following the push-pull operation of the handle 11 to release the holding state of the latch 33 by the interlocking mechanism 35 and to project the projecting rod 37;
When the door 13 is closed, the door 13 is disposed on the building-side frame 75 that faces the wooden mouth 13c side of the door 13, and contacts the protrusion 13 when it protrudes, and is substantially orthogonal to the protruding direction of the protrusion 37. A contact portion 73 that swings the door 13 together with the protrusion of the protrusion 37 in the opening direction of the door 13;
It is characterized by comprising.

Claims

It has a latch that can be moved forward and backward from the door end of the door, and has an interlocking mechanism that holds the latch in an advanced state and releases the held state, and is provided on the front and back surfaces of the door so as to be movable in the contact and separation directions. In the opening assist mechanism in which the handle is pushed or pulled in the opening direction of the door to allow the latch to move backward or backward through the interlocking mechanism and the door is opened.
A protruding ridge that can protrude from the door end of the door;
A cam plate that follows the push-pull operation of the handle and rotates in one direction to release the holding state of the latch by the interlocking mechanism and to project the protruding hook;
When the door is closed, it is disposed on the building-side frame facing the door end of the door, contacts when the protruding rod protrudes, and opens in the door opening direction substantially orthogonal to the protruding direction of the protruding rod. A contact portion for swinging the door together with the protrusion of the protrusion,
An opening assist mechanism characterized by comprising:

The opening assist mechanism according to claim 1,
The cam plate is rotatably supported on a support shaft in a direction along the door thickness direction, and has a pair of arm portions projecting radially outward across the support shaft. Each of the operating pieces from the pair of grips abuts on the surface opposite to the door rotation side, and one of the arm portions projects the projecting rod against the rotation side when the door is opened. Opening assistance mechanism.

The opening assist mechanism according to claim 1 or 2,
An opening assist mechanism, wherein the latch is an inverting latch.

An opening assist mechanism according to any one of claims 1, 2, and 3,
The interlocking mechanism has at least one swinging member that is swingably supported by a swinging shaft in the same direction as the support shaft.
The swing member is pressed by one swing end sandwiching the swing shaft by rotation of the cam plate when the door is opened, and a restricting portion provided at the other swing end sandwiching the swing shaft is latched. An opening assisting mechanism, wherein the latch is released from the release state to release the holding state of the latch.
