Description

  The present invention relates to a hinge and a fitting, and more particularly, to a hinge capable of restricting an opening angle of a door to a predetermined angle and a metal fitting attached to the hinge.

  2. Description of the Related Art Conventionally, when a door is attached to a building such as a house, a frame is attached to a wall, and the door is attached to this frame via a door hinge so that the door can be opened and closed. In this case, if the door is opened without limitation, due to the layout, depending on the layout of other doors, equipment and articles installed in the room, the door itself and the handle etc. may be on the wall or other articles. There was a problem of collision and damage.

  Conventionally, against such a problem of breakage, a stopper metal is provided on a floor, a wall, a frame, or the like, separately from a hinge, and when the door is opened to a predetermined angle, the stopper is moved to the door or the wall. In contact with one, the door was regulated so that it would not open any further.

  However, in the above-described conventional stopper, it is necessary to attach the door to a frame or the like via a hinge and then project the door to a floor, a wall, or a frame. In addition, there is a problem in that it is not provided with a good appearance because it is protruded on any one, and when it is protruded on the floor surface, it interferes with walking or the like.

  Therefore, Patent Literature 1 discloses a door hinge (hinge) that can regulate the door at a predetermined angle without performing a stopper attaching operation other than attaching the door.

Japanese Utility Model Publication No. 5-35988

  However, the hinge described in Patent Literature 1 has a structure in which a stopper piece protrudes from a movable piece, so its appearance is not so good as a conventional stopper, and once installed, a predetermined angle at which the door can be opened can be changed. There was no problem.

  The present invention has been made in view of the above-described problems, and has a specific object of being able to be used integrally with a hinge without any other obstacles such as a stopper, and a predetermined limit angle at which a door can be opened easily. An object of the present invention is to provide an opening limit hinge and its parts that can be set and easily changed.

  The present invention has been devised to achieve the above object. To be more specific, the hinge is a hinge for supporting the door so that it can be opened and closed with respect to the frame, a fixed blade fixed to the frame, and a spindle fitted to the fixed blade. A movable blade plate rotatably inserted into the support shaft and fixed to the door; and an opening limiting ring disposed in a gap between the fixed blade plate and the movable blade plate and inserted into the support shaft. The fixed blade plate has a cylindrical fixed cylinder portion, and a substantially flat blade portion protruding from the peripheral surface of the fixed cylinder portion, and the movable blade plate is cylindrical and has a support shaft. And a substantially flat plate-shaped blade portion protruding from the peripheral surface of the insertion tube portion, and the opening restriction ring is fitted with one of the blade portions. And an angle limiting slit that limits the rotation of the other blade.

  The opening limit hinge of the present invention has an effect that the limit angle at which the door can be opened can be easily set and changed easily by using the opening limit ring integrally with the hinge for the door. Furthermore, there is no need to attach other metal fittings such as stoppers other than hinges, which can reduce the man-hours of installation work and the component cost of metal fittings, and the parts other than hinges do not protrude. The effect which cannot be obtained is obtained.

  In the present invention, the opening restriction ring has a cylindrical shape with an inner diameter slightly larger than the outer diameter of the fixed cylindrical portion and the insertion cylindrical portion, and is oriented in the axial direction from one end portion in the axial direction. And a fitting groove portion that fits with the one blade portion, and a rotation angle of the blade portion that is formed by being axially cut from the other end portion in the axial direction and abutting on the other blade portion. The angle limiting slit for limiting to an angle, the fitting groove and the angle limiting slit are not communicated with each other, and are locked by the blades formed in the gap between the fitting groove and the angle limiting slit. And a thickness of the locking rib portion is slightly smaller than a gap between the fixed blade plate and the movable blade plate.

  The opening restriction hinge of the present invention can freely set the opening angle of the door simply by selecting the restriction angle of the angle restriction slit portion. There is an effect that it is possible to change the maximum angle at which the door opens simply by replacing the door with one having a different limit angle.

  Also, in the present invention, the opening restriction ring is screwed to the female screw portion penetrating from the required position on the outer peripheral surface to the inner peripheral surface, and the distal end portion can contact the fixed cylindrical portion. A configuration having an external thread is included.

  Since the opening limiting ring of the present invention can fix the opening limiting ring to the fixed cylindrical portion with a screw, the contact vibration between the blade and the fitting groove when the door is opened can be reduced, and the respective wear is suppressed. There is an effect that can be done.

  Further, the present invention includes a configuration in which a cushioning member made of a synthetic rubber material or the like is provided at a required position of the blade portion where the angle limiting slit portion abuts.

  The opening limiting hinge of the present invention has a cushioning material provided at a required position of the blade, thereby reducing impact and noise reduction when the blade and the angle limiting slit come into contact with each other, as well as reducing wear. There is an effect that can be suppressed.

  The present invention provides an opening limiting ring used for the opening limiting hinge, wherein the inner diameter of the opening limiting ring and the locking rib portion can be arranged on an existing so-called insertion hinge or anti-seismic hinge. A configuration formed by the thickness and the width of the fitting groove portion is included.

  Since the opening restriction ring of the present invention can be disposed on an existing so-called insertion hinge or anti-seismic hinge, only the opening restriction ring of the present invention is disposed on the installed hinge, and the opening restriction hinge and The same effect is obtained.

  The opening restriction hinge and the opening restriction ring of the present invention have no obstacles since metal fittings other than the hinge are not installed separately from the hinge, and can only limit the predetermined angle at which the door can be opened easily. In addition, there is an effect that it is easy to change the predetermined angle once set.
