Description

  The present invention is an anti-seismic hinge for attaching the door to the frame so that it can be freely opened and closed, and the axial height of the anti-seismic hinge can be adjusted so that the door and the frame do not interfere when the door is suspended. The present invention relates to an anti-seismic hinge that can open a door by absorbing the deformation even when an external force such as an earthquake deforms the frame.

An anti-seismic hinge that can open a door even when the frame is deformed by an external force such as an earthquake is known (see, for example, Patent Document 1). As shown in FIG. 6, the anti-seismic hinge shown in Patent Document 1 includes a shaft-side blade 1 and a receiving-side blade 2, and the shaft-side blade 1 forms a tube portion 3 and a mounting hole 4 for a frame. The blade plate 5, the star 6 fixed to the end of the tube portion, the lower retaining ring 7 provided in the tube portion, and the lower washer 8 are integrally inserted in the tube portion so as to move up and down and rotate. And a compression coil spring 10 that urges the shaft upward to a position where the lower washer hits the lower retaining ring . Further, the receiving blade 2 is fixed to the tube portion 11 through which the shaft 9 is relatively vertically moved and pivoted, a blade plate 13 having an attachment hole 12 to the door, and the tube portion end. and Giboshi 14, the retaining ring 15 on which is provided inside the tube unit, a vertically movable upper seat gold 16, the compression coil spring 17 to the upper seat gold biases the upper seat gold down to a position impinging on the on stop ring Have Then, as shown in FIG. 6 (A), the tip of the shaft 9 of the shaft-side blade 1 is inserted into the tube portion 11 of the receiving-side blade 2, and its tip abuts against the upper washer 16, so that the normal state Thus, it is assembled in a state where a movable space 18 of about 10 mm serving as a compression allowance is provided between the upper end of the shaft side blade 1 and the lower end of the receiving side blade 2. Usually, the door is attached to the frame using two to three pairs of anti-seismic hinges. When the frame is deformed by an earthquake or the like and an overload acts on the door, the compression coil springs 10 and 17 incorporated in the shaft-side blade 1 and the receiving-side blade 2 bend, and the tip of the shaft, the lower washer 8, and the upper washer 16 However, since the movable space 18 between the upper surface of the shaft-side blade 1 and the lower surface of the receiving blade 2 is reduced by the amount of entering, the door can be opened and closed by absorbing the overload. The periphery of the movable space 18 is covered with a cover 19. As an anti-seismic hinge, there is also known a structure in which a shaft is fixed to a pipe portion without providing a compression spring on the shaft-side blade, and the shaft-side blade is movable up and down relative to the receiving blade. (For example, refer to Patent Document 2).

  As described above, the anti-seismic hinge has a configuration in which a movable space serving as a compression allowance is provided between the shaft side blade and the receiving blade, and the receiving blade and the shaft blade have the predetermined movable space. If it is not correctly attached to the frame and the door, the effect expected in the event of an earthquake or the like cannot be exhibited. Normally, when the door is suspended, a gap of about several millimeters is provided between the lower surface of the upper frame and the upper surface of the door, and between the upper surface of the lower frame and the lower surface of the door in consideration of smooth opening and closing and appearance. However, if the mounting holes are machined out of position, or when the blades are attached to the door with mounting screws, the door is correctly suspended if the mounting position of the female screw provided on the door is offset from the predetermined position. However, the gaps are too small or too large. In an extreme case, the door and the frame may interfere with each other and the door may not close.

  As described above, when the door mounting position is not correct and the door position is too high or too low, the conventional general-purpose flag hinges have a hinge that allows the height to be adjusted. (See, for example, Patent Documents 3 and 4). For example, in Patent Document 3, a cap capable of storing a plurality of adjustment pieces is provided between the shaft tubes, and the height of the blade plate can be adjusted up and down by increasing or decreasing the number of adjustment pieces. Yes. Further, in the device described in Patent Document 4, an adjustment screw is screwed into the pipe from the upper part of the shaft cylinder, the lower end of the adjustment screw is brought into contact with the support shaft via a sphere, and the adjustment screw is advanced and retracted to increase the height of the blade plate. It is configured to change the height. However, such a configuration cannot be adopted for the anti-seismic hinge. That is, in the anti-seismic hinge as described above, a predetermined movable space that becomes a compression allowance must be secured between the shaft-side blade and the receiving blade in the event of an earthquake or the like. With the configuration in which the number of adjustment pieces inserted between the blade plates is increased or decreased as described, a movable space serving as a compression allowance cannot be secured between the blades. Further, in the configuration in which the adjustment screw is screwed from above the pipe portion and the tip thereof is brought into contact with the support shaft as described in Patent Document 4 above, the space where the compression coil spring is bent and the washer is allowed to move in the event of an earthquake. Can not be secured. As described above, it is difficult to adopt the adjustment mechanism known in the conventional general-purpose flag hinge as it is for the anti-seismic hinge.

Go up. Therefore, the gap at the upper part of the door is A−X = a mm, the gap at the lower part of the door is B + X = bmm, the gap at the upper part which should be originally narrowed, and the gap at the lower part is widened. As shown in FIG. 7 (D), when the position of the receiving blade 2 is normal and the shaft blade 1 attached to the frame 21 is mounted Xmm below the normal position, the door is only Xmm. Go down. Therefore, the gap at the upper part of the door is A + X = cmm, the gap at the lower part of the door is BX = dmm, the upper gap that should be originally widened by Xmm, and the lower gap is narrowed by Xmm. The door mounting position varies depending on various other mounting modes.

  When the mounting position changes as described above, in the anti-seismic hinge, a movable space as a compression margin must be secured between the shaft side blade and the receiving blade, and the compression between the shaft end and the star is compressed. Since the coil spring and the washer which can be moved up and down are provided, it is not possible to provide an adjustment mechanism as in the case of a conventional general-purpose flag hinge. Therefore, according to the present invention, the above-described problems have been solved by changing the length of the shaft to be inserted into the pipe portion so as to cope with it.
