Description

  The present invention relates to a hinged door unit.

  When attaching the door attached to the entrance of the room to the attachment frame with a hinge, it is necessary to adjust the gap between the door and the attachment frame appropriately so that the door can be opened and closed smoothly.

  In addition, the gap between the door and the mounting frame is determined in the thickness direction of the door (inside / outside direction of the mounting frame), the width direction of the door (left / right direction of the mounting frame), and the height direction of the door (up / down direction of the mounting frame). , Must be adjusted in three directions orthogonal to each other.

  And, in the adjustment of the gap in the three directions perpendicular to each other between the door and the mounting frame, there is a hinged door unit that can be performed independently and collectively inside or outside with the door closed. It has already been devised (Japanese Patent Laid-Open No. 2007-231521: Patent Document 1).

It is an enlarged front view of the principal part of the regulation state. It is the front view seen from the inside of the hinged door unit which has already been devised. It is a side view of the door unit with a hinge shown in FIG. It is a disassembled perspective view of the lower hinge in the door unit with a hinge shown in FIG. It is a perspective view of the lower hinge part in the door unit with a hinge shown in FIG. It is a disassembled perspective view of the upper side hinge in the door unit with a hinge shown in FIG. It is a perspective view of the upper side hinge part in the door unit with a hinge shown in FIG.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  The hinged door unit according to the embodiment of the present invention is the same as the above-described hinged door unit in the configuration of the lower hinge and the upper hinge for attaching the door to the mounting frame so as to be freely opened and closed. Therefore, common parts are denoted by the same reference numerals, and detailed description thereof is omitted here.

  Thus, a feature of the first embodiment of the present invention shown in FIGS. 1 and 2 is that the upper hinge 127 is provided with the movement restricting means 1 below the frame side holding shaft 146.

  Further, in the present embodiment, a female screw 2 is provided at the front portion of the front / rear slider 134 and a regulating screw 3 screwed into the female screw 2 is used as the movement restricting means 1 below the frame side holding shaft 146 in the upper hinge 127. The tip is used as a means for performing strong pressure contact with the peripheral surface of the frame-side holding shaft 146 through the screw insertion hole 4 provided in the side portion of the cylindrical body 145.

  By providing the movement restricting means 1, even if the door 102 is opened and closed vigorously and frequently, the frame-side holding shaft 146 can be reliably prevented from coming off from the cap-shaped receiving member 129. Is. In addition, as the pressure expansion coil spring 149 for pressing the frame-side holding shaft 146 upward, an expensive spring with strong elasticity has been conventionally used. However, according to the present embodiment, the elasticity is However, it is sufficient to use an inexpensive one that is not so strong, and the cost can be reduced accordingly.

  Next, a second embodiment of the present invention shown in FIGS. 3 to 5 will be described.

  In the present embodiment, as the movement restricting means 1 below the frame side holding shaft 146 in the upper hinge 127, a long hole 6 is formed in the substrate portion 5a along the axial direction and at a right angle to the lower end of the substrate portion 5a. An L-shaped restriction plate 5 formed by coupling the pressure contact portions 5b is attached to a side portion of the storage case 132 with screws 7 inserted into the long holes 6, and the pressure contact portions 5b of the L-shaped restriction plate 5 are framed. This is done by pressing against the lower end surface of the side holding shaft 146.

  Thus, before the door 102 is attached to the attachment frame 101, a state in which the door 102 is pulled down against the action of the pressure expansion coil spring 149 of the frame side holding shaft 146 is held using a temporary stopper (not shown). At this time, as shown in FIG. 3, the L-shaped regulating plate 5 is lowered, and the pressure contact portion 5b is separated by a distance L.

  Further, when the temporary stopper is attached or detached, as shown in FIG. 4, the L-shaped restricting plate 5 is turned around the screw 7 so as not to obstruct the same, and the press contact portion 5b is shifted outward.

  When the downward movement of the frame-side holding shaft 146 is restricted, as shown in FIG. 5, the L-shaped restriction plate 5 is shifted upward so that the press contact portion 5 b is the lower end surface of the frame-side holding shaft 146. This state is held by tightening the screw 7.
