Description

  The present invention relates to a pivot hinge mounting structure for rotatably supporting a door panel that opens and closes an opening of a room or storage in a house.

  An example of a conventional pivot hinge mounting structure is disclosed in Patent Document 1. As shown in FIGS. 10 and 11, the pivot hinge attachment structure 1 includes a frame body side support member 4 attached to a frame body 3 provided in an opening 2 and a door panel side attached to a door panel 5. It is comprised by the supporting member 6. FIG.

  The frame side support member 4 includes a frame body fixing portion 4a fixed to the frame body 3, a pivot support portion 4b formed extending in the horizontal direction from the lower portion of the frame body fixing portion 4a, and an upper surface of the pivot support portion 4b. And a frame fixing part 4 a is fixed to the frame 3 using a fixing screw 7. The door panel side support member 6 includes a door panel fixing portion 6a fixed to a lower end portion of the door panel 5, a bearing body support portion 6b formed extending in a horizontal direction from a lower portion of the door panel fixing portion 6a, and a bearing body. And a through hole (not shown) communicating with the internal space of the bearing body 6c is formed in the bearing body support 6b.

Then, the pivot 4c is inserted into the bearing body 6c from below, and the door panel fixing portion 6a is inserted into the digging portion 9 opened in both the lower end surface 5a and the width direction end surface 5b of the door panel 5, The door panel fixing portion 6 a is fixed to the door panel 5 using two fixing screws 8.
JP 2006-291545 A

  In the conventional pivot hinge mounting structure 1 (FIG. 10), since the digging portion 9 formed in the door panel 5 is opened on both the lower end surface 5a and the width direction end surface 5b of the door panel 5, In the two wall portions 9a and 9b of the digging portion 9 facing each other in the thickness direction, the lower end portion and the one side end portion thereof could not be reinforced by the adjacent “wall portion”. Therefore, when the opening / closing operation of the door panel 5 is repeated, the wall portions 9a and 9b are deformed outward by the force acting on the wall portions 9a and 9b from the door panel fixing portion 6a, as shown in FIG. There was a problem that the designability was impaired.

  Further, when the wall portions 9a and 9b are deformed outward, a gap is generated between the inner surface and the outer surface of the door panel fixing portion 6a. There was a risk of rattling.

  Therefore, the main problem of the present invention is that it is possible to prevent the door panel design from being impaired by preventing undesired deformation of the door panel, and to effectively prevent "backlash" of the door panel fixing portion. It is to provide a pivot hinge mounting structure.

The invention as set forth in claim 1, with respect to the frame 14 provided in the opening 12 which is opened and closed by the "door panel 16, the frame body side support member 32 having a frame fixing portion 36 fixed to the frame 14 When, a door panel support member 34 having a door panel fixing part 46 fixed to the door panel 16, one of the frame side support members 32 or the door panel supporting member 34 has a pivot 40 And the other is a pivot hinge mounting structure 10 having a bearing body 50 for pivotally receiving the pivot 40, wherein the door panel fixing portion 46 is formed on the lower end surface of the door panel 16. It has a horizontal plate portion 52 to be abutted and a fitting convex portion 18 erected on the upper surface of the horizontal plate portion 52, and the fitting convex portion is provided on the lower end surface 16 a of the door panel 16. Horizontal sectional shape of at least part of 18 Have the same horizontal cross-sectional shape, and the fitting projection 18 fitting hole 20 is fitted is formed,
The fitting convex portion 18 is disposed to extend in the width direction of the door panel 16, the fixed block 58 fixed to the horizontal plate portion 52, the movable block 60 fixed to the door panel 16, and A male screw member 62 that is rotatably locked to one of the fixed block 58 or the movable block 60 and screwed into a female screw 66 provided on the other of the fixed block 58 or the movable block 60, and the door panel 16. A fixed screw 68 extending in the width direction and screwed to the fixed block 58 and the movable block 60;
A through hole 24b through which a tool 22 for rotating the male screw member 62 is inserted in the wall portion 20c of the fitting hole 20 constituting a part of the width direction end face 16b of the door panel 16 and the fixing A pivot hinge having a through-hole 24a through which a tool 22 for rotating the screw 68 is inserted extends from the end face 16b in the width direction of the door panel 16 to the fitting hole 20. Mounting structure 10 ”.

In the present invention, the fitting hole 20 is formed in the lower end surface 16 a of the door panel 16, and the fitting projection 18 of the door panel fixing portion 46 is fitted into the fitting hole 20. The fitting hole 20 is a recess opened only in the lower end surface 16 a of the door panel 16 (a state in which the periphery is surrounded by the wall portions 20 a, 20 b, and 20 c of the door panel 16 ) , and the width direction end surface 16 b of the door panel 16. There is no opening. Therefore, the two wall portions 20a and 20b of the fitting hole 20 facing each other in the thickness direction of the door panel 16 are reinforced by the wall portion 20c of the fitting hole 20 constituting a part of the width direction end surface 16b of the door panel 16. Thus, the two wall portions 20a and 20b facing each other in the thickness direction are not undesirably deformed. In addition, since the horizontal cross-sectional shape of the fitting hole 20 is the same as the horizontal cross-sectional shape of at least a part of the fitting convex portion 18, the fitting hole 20 corresponds to irregularities with substantially the same sectional shape during fitting , and the gap between the irregularity-corresponding surfaces is horizontal. The gaps in the direction are not uneven and are fitted substantially uniformly. For this reason, it is difficult to cause a single contact between the concave and convex corresponding surfaces, and the “fluctuation” of the fitting convex portion 18 in the fitting hole 20 does not occur.

Further, in the present invention, the position of the movable block 60 with respect to the fixed block 58 can be adjusted by the male screw member 62 and the female screw 66, whereby the position of the door panel 16 with respect to the frame body 14 can be adjusted. When the position adjustment of the door panel 16 is completed (see FIG. 2), the fixing screw 68 is inserted from the lower through hole 24a, and the fixing screw 68 is screwed into the screw holes 70 and 72 using the tool 22. Thus, the movement of the movable block 60 relative to the fixed block 58 is fixed. That is, the movement of the door panel 16 with respect to the frame body 14 can be fixed.

According to the invention described in claim 1, the two wall portions 20 a and 20 b of the fitting hole 20 facing each other in the thickness direction of the door panel 16 are part of the width direction end face 16 b of the door panel 16. and thus it is reinforced to be connected to the wall portion 20c of the hole 20. Therefore, even when a force acts on the inner surfaces of the wall portions 20a and 20b of the fitting hole 20 from the fitting convex portion 18, the two wall portions 20a and 20b are in a reinforced connection state and are not directed outward. It can prevent that it deform | transforms as desired and can prevent that the designability of the door panel 16 is impaired. Further, coupled with the fact that the horizontal cross-sectional shape of at least a part of the fitting convex portion 18 is the same as the horizontal sectional shape of the fitting hole 20, Can be effectively prevented.

Moreover, since one end of the through hole 24b is opened in the width direction end surface 16b of the door panel 16, the tool 22 can be easily inserted into the through hole 24b, and the position adjustment work of the door panel 16 can be easily performed. Can do. Moreover, since the through-hole 24b opened to the width direction end surface 16b of the door panel 16 is not conspicuous from the outside, it can prevent that the design property of the door panel 16 is impaired by the through-hole 24b.
