Description

  The present invention relates to a self-closing type sliding hinge, and is particularly used for furniture such as a cabinet, a door, and a window, and a building. The furniture and the building have, for example, two upper and lower horizontal edges and two left and right vertical edges. The present invention relates to an automatic closing slide hinge for connecting a door body to one edge of an opening formed from the opening so as to be openable and closable.

  A conventional automatic closing slide hinge is, for example, a first attachment member fixed to one edge of the opening and a second attachment member fixed to the door body as disclosed in Japanese Patent Application Laid-Open No. 7-119347. The four support shafts are rotatably connected to each other with four support shafts between the mounting members and the urging means for urging the turning force in the closing direction. There is one in which a torsion spring is attached to an appropriate one of them. This automatic closing slide hinge can accumulate the closing force by the urging means when the door is opened, but the closing force is released at the moment when the door is released from the opening position, so that the closing speed is increased. However, there is a drawback in that it is quite fast, and the impact force when reaching the door closing position is large, making a large loud impact sound and possibly damaging the hands and fingers of persons entering and exiting.

  The device disclosed in Utility Model Registration No. 3090408 is an improvement over the above-mentioned disadvantages of the prior art. This invention is for connecting a door body to one edge of the opening so as to be openable and closable with the opening, and a first mounting member fixed to the one edge and a second fixing member fixed to the door body. 2 mounting member, and a first link whose both ends are pivotally connected to the first and second mounting members, respectively, so as to be located between the first link and the one edge. A second link having both ends pivotally connected to the first and second mounting members, respectively, and one end pivotally connected to an end of the second link pivotally connected to the first mounting member. The sliding hinge is an automatic door closing slide hinge which is in contact with the other end and a shock absorber with a biasing means held by the first mounting member.

  The automatic closing slide hinge having such a configuration accumulates the closing force by the shock absorber with the urging means when the door is opened, and relaxes the release of the closing force by the shock absorber with the urging means when the door is closed. It is characterized by being able to. With reference to the specification and the drawings of the present invention, the shock-absorbing device with the urging means is not a torsion spring but an air spring in one of two chambers separated by a biston, and the urging means, The holding of the other end to the first mounting member is not pivotal, but can be moved only to the left and right by adjustment.

  However, the shock absorber of the automatic closing slide hinge having such a configuration has a good property of accumulating the urging force because the air is originally incompressible even if the air spring is provided as the urging means. Absent. Further, the shock absorber is configured such that the other end is not a pivotable pivot, but can be moved only to the right and left by adjustment, and one end of the shock absorber is the second link. Since it is pivotally connected to the end pivotally connected to the first mounting member, when the second link is pressed to swing by this, the one end must move in an arc shape. Therefore, there is no danger of failure because the second link is locked and cannot operate, or the piston rod operates while being bent by being pressed by the second link.

  In view of the above problems of the prior art, the present invention not only can reduce the impact force at the time of closing the door to eliminate a loud impact sound at the time of closing, but also at the time of operation, there is no locking and pressure, It is an object of the present invention to provide an automatic closing slide hinge capable of smoothly expanding and contracting a piston rod.

  In order to achieve the above object, the automatic hinged sliding hinge according to the present invention is characterized in that the door hinge is connected to one edge of the opening so that the door can be opened and closed with respect to the opening. A first attachment member fixed to the one edge portion, a second attachment member fixed to the door body, and a first attachment member having both ends pivotally connected to the first and second attachment members, respectively. A link; a second link having both ends pivotally connected to the first and second mounting members, respectively, so as to be located between the first link and one edge; A torsion spring disposed at one of the four ends of the first link and the two ends of the second link so as to urge the rotating force in the direction, a cylinder body, and a piston rod. And one end of the piston rod, which is a tip end, and the cylinder An oil cylinder device having the other end, which is the end of the body, and the other end held by the first mounting member; and one end pivotally connected to one end, which is the tip of the piston rod. A transmission link means pivotally connected to an end of the second link pivotally connected to the first mounting member, wherein a piston rod of the oil cylinder device is When the door is opened, the end of the second link is pivotally connected to the first mounting member via the transmission link means, and is pulled by the end when the door is closed. It is in.

  Further, both ends of the first link are pivotally connected to the first and second mounting members by pivot pins, respectively, and the second link is connected to the first link and the one edge. Preferably, both ends are pivotally connected to the first and second mounting members by pivot pins respectively.

  Further, the transmission link means comprises a first transmission link pivotally supported by the first mounting member and having one end and the other end, and a second transmission link having one end and the other end, One end of the first transmission link is the one end of the entire transmission link means, the other end is pivotally connected to one end of the second transmission link, and the other end of the second transmission link is the transmission link. Preferably, it is the other end of the entire means.

  When the door is opened, the automatic closing slide hinge having such a configuration must resist the elastic return force of the torsion spring, so that the door closing force can be accumulated. Since the piston rod of the cylinder device must be pulled, the door closing force released from the torsion spring can be reduced, so that the impact force at the time of closing the door can be reduced and the impact sound at the time of closing the door can be eliminated. In addition, since the transmission link means as described above is attached between the distal end of the piston rod and the end of the second link pivotally connected to the first attachment member, it is locked during operation. Without any pressure, the piston rod can be smoothly expanded and contracted.

  Hereinafter, a preferred embodiment of the present invention will be described in detail. In the following description, components having substantially the same function and configuration will be denoted by the same reference numerals, regardless of their size, and repeated description will be made only when necessary.
