Description

  The present invention uses a pivot hinge to connect the suspension base side to the upper and lower corners of the door frame so that the hinged door is pivotably suspended. TECHNICAL FIELD The present invention relates to a warp prevention straightening device for hinged doors that prevents and corrects.

  Recently, for example, as shown in FIG. 13, the hinged door is mounted inconspicuously and has a good appearance. Therefore, a pair of pivot hinges 1 and 2 are used at the top and bottom, and a pivot shaft and a bearing provided in the pivot hinges are used. With the fitting of the holes, the suspension base side is pivotably connected to the upper and lower corners of the door frame 3 and suspended. Further, when the hinged door 4 is a vertically long panel and is made of a material such as wood, which is likely to warp in a bow shape over time, a warp preventing metal fitting 5 is mounted between the pivot hinges 1 and 2, and the warp preventing metal fitting 5 is provided. In this way, it is connected to the door frame 3 to prevent warping deformation. The warpage prevention device 5 has a pin joint structure in which a pair of intermediate hinge bodies 5a and 5b are vertically stacked and one is screwed to the door frame 3 side and the other is screwed to the opening door 4 while being connected by a pivot shaft 5c. In combination with the upper and lower pivot hinges 1 and 2, the hinged door 4 is rotatably connected to the door frame 3 (see Patent Document 1).

  However, in the conventional anti-warping device 5 for the hinged door described above, not only the upper and lower pivot hinges 1 and 2 but also the protrusion between the hinge hinges on the suspending side of the hinged door 4, the appearance around the door is deteriorated. In particular, the door area has a problem in that it is contrary to such a requirement because the design requires a flat appearance with fewer protrusions.

  Therefore, conventionally, in the hinged door prevention apparatus, as shown in FIG. 14 and FIG. 15A, for example, the mating surfaces 3a are arranged so that the component parts do not protrude between the hinged door 4 and the door frame 3. -There are some which try to prevent the warp deformation of the hinged door by assembling the components in 4a.

In this conventional hinged door prevention device, the male device 6 having the protruding portion 6 a is fixed to the mating surface 3 a of the door frame 3, while the female device 7 having the recess 7 a is aligned on the hanging side of the hinged door 4. When fixed to the surface 4a and the hinged door 4 is closed, as shown in FIG. 15 (B), the projecting portion 6a is fitted into the recess 7a to connect the hinged door 4 to the door frame 3, thereby It has a structure for forcibly preventing warpage deformation (see Patent Document 2).

  By the way, the conventional anti-warping device for hinged doors certainly does not warp deformation by connecting the hinged door 4 to the rigid door frame 3 and forcibly restricting the warp deformation while the hinged door 4 is in the closed state. It can be prevented, but once the hinged door 4 is opened and the fitting of the male appliance 6 and the female appliance 7 is disengaged, the hinged door 4 is deformed with a large amount of warpage, with the reaction of the forced warping regulation being released at once. It has been. Therefore, according to this conventional warp prevention device, even if the hinged door 4 is opened and then closed as shown in FIG. 15C, the hinged door 4 is already warped and deformed when opened. 7 and the male appliance 6 are misaligned, so that the female appliance 7 cannot collide with the male appliance 6 and cannot be closed. As a result, the opening and closing of the hinged door 4 is hindered. If the door cannot be closed, there has been a problem that it is impossible to prevent warp deformation of the hinged door 4 during closing.

  Accordingly, the object of the present invention is to prevent the warpage of the hinged door and to prevent the correction of the warp deformation of the hinged door without obstructing the opening and closing of the hinged door. To provide an instrument.

  Therefore, in order to solve the above-described problem, the anti-warping corrector R for hinged door according to the first aspect of the present invention uses, for example, a pivot hinge P (P1, P2) as shown in the following embodiment. The hinged door D is connected to the upper and lower corners 11a and 11b of the door frame A and is pivotably suspended. The hinged door D is connected to the door frame A between the upper and lower pivot hinges P1 and P2, and the hinged door is connected. A device for preventing and correcting warpage deformation of D, and when the hinged door D is in a closed state, the frame side warpage assembled to the end surface 21 of the vertical frame 11 of the door frame A facing the suspension side end surface 22 of the hinged door D. And a door side correction means 30 assembled to the suspension side end face 22 of the hinged door D facing the frame side warpage prevention correction means 25, and the frame side warpage prevention correction means 25 includes a flange 31 and a frame 31. , The flange 1 has a protrusion 32 protruding from above, and a long hole 33 is provided in the flange 31, while the protrusion 32 is formed along the long hole 33 with a thick root pressing part 36 and the pressing part 36. Both side surfaces 35a and 35b are inclined and extend so as to become thinner toward the tip, and both side surfaces 35a and 35b of the guide projection 35 are formed on both sides of the vertical frame 11 when assembled. The flange 31 is applied to the end surface 21 of the vertical frame 11 in a direction matching the surfaces 55 and 56, and a set screw 37 is passed through the elongated hole 33 so that the assembly position can be moved and adjusted. The side warpage prevention correction means 30 is provided with a guide hole 45, a guide case 38 that fixes the guide hole 45 to the projection end 32 so as to oppose the projection 32, and the guide case 38 guides the guide. Invoke freely from hole 45 A movable correction tool 39 to be held; and a biasing spring 40 that constantly biases the movable correction tool 39 in a direction protruding from the guide hole 45. While the engaging recess 51 is engaged with the projection 32 on the frame side, when the hinged door D warped and deformed when opened, the hinged door D is pressed against the pressing portion 36 of the projection 32 so that the hinged door D is closed. A pressing projection 50 that is pressed by the pressing portion 36 on the frame side protrudes in a direction in which the warp deformation of the hinged door D is corrected as it rotates.

  Therefore, according to the first aspect of the present invention, when the hinged door is in the closed state, the projection 32 on the frame side is engaged with the engagement recess 51 of the movable corrector 39 on the door side between the upper and lower pivot hinges P1 and P2. Combined, the hinged door D is connected to the rigid door frame A, which causes the hinged door D to warp and deform even if there is a difference in temperature or humidity between the inside and outside of the hinged door D over time. Is forcibly prevented. On the other hand, while the hinged door D is in the closed state, the hinged door anti-warp correction device R of the present invention is connected to the door frame A, so that it is forcibly restricted from warping, but the hinged door D is opened. Thus, when the engagement between the projection 32 on the frame side and the engagement recess 51 of the movable correction tool 39 on the door side is released, the hinged door D is greatly warped and deformed due to the reaction in which the forced warpage restriction is released at once. However, in the warp prevention device R of the present invention, when the hinged door D that is warped and deformed when it is opened is rotated in the closing direction, the pressing convex portion 50 of the movable corrector 39 on the door side is guided by the projection 32 on the frame side. The guide convex portion 35 is guided so that the door side warpage prevention correction means 30 does not collide with the frame side warpage prevention correction means 25 on the inclined side surface while sliding on either of the inclined side surfaces 35a and 35b of the protrusion 35. Then, the projection 32 is engaged with the engagement recess 51, and then the pressing projection 50 of the door-side movable correction tool 39 presses against the root-side pressing portion 36 of the frame-side projection 32, and then the hinged door D rotates. As the door is closed, the pressing convex portion 50 is gradually and strongly pressed by the fixed pressing portion 36 in a direction in which the warp deformation of the opening door D is corrected. Correct in advance while closing.

The invention according to claim 2 is the warp prevention straightening device R for hinged doors according to claim 1, for example, the frame side warpage prevention correction means 25 includes a mounting plate 23 as shown in the embodiment shown below. At the time of assembly, the flange 31 is superimposed on the mounting plate 23 and fixed to the end surface 21 of the vertical frame 11, and parallel straight notches are formed on both the mounting plate 23 and the mating surfaces 23a and 31a of the flange 31. It is characterized in that it is formed with non-slip stoppers 29 and 34 that are engraved side by side in the width direction.

  Therefore, according to the first aspect of the present invention, since the hinged door is opened, even if the warpage deformation that has been suppressed at the time of closing occurs in the hinged door, the warpage deformation is corrected in advance while closing the hinged door each time. Then, since the projection of the frame side warpage prevention correction means engages with the engagement recess of the movable correction tool of the door side warpage prevention correction means to connect the hinged door to the door frame, the frame side warpage prevention correction means is connected to the door side. Occurrence of a problem that the warp prevention correction means may not be able to close the hinged door due to a collision, which may interfere with the opening / closing of the hinged door D, or the hinged door will not be closed and thus cannot exhibit the effect of preventing warpage deformation when closed. Can be prevented.

  According to the second aspect of the present invention, the anti-slip which is formed by arranging a large number of parallel straight notches in the width direction of the plate is attached to both the overlapping surfaces of the flange and the mounting plate on which the frame side warp prevention correcting means are overlapped. Therefore, when adjusting the movement by moving the flange back and forth in the width direction of the end face of the vertical frame, it is possible to easily and accurately position the frame side warp prevention correction means at the optimum mounting position while suppressing excessive movement, Once the frame side warpage preventing correction means is fixed at the mounting position, it can be firmly fixed without shifting due to the meshing of the parallel notches.

The case main body 41 includes a rice bowl-shaped guide part 43 and attachment hook parts 44 extending symmetrically on both end sides sandwiching the guide part 43 therebetween. The guide part 43 is provided with a guide hole 45 of a vertically long rectangular hole according to the outer shape of the movable correction tool 39, and the inlet opening 46 of the guide hole 45 is formed on the mounting flange part 44 side, while being opened on the opposite side. A pair of lid receiving portions 43a are provided on both end sides with the bottom opening 47 interposed therebetween. Further, at the four corners of the inner wall of the guide hole 45, convex strips 43b having the same length are provided from the hole edge of the inlet opening 46 to the bottom opening 47, and the regulation step portion is provided on the bottom opening 47 side of the convex strip 43b. 43c is formed. The bottom lid 42 is a plate having a semicircular shape at both ends in the longitudinal direction in accordance with the contour shape of the guide portion 43, and a circular spring receiving recess 42 a is provided in the center of one surface thereof.

  The movable correction tool 39 includes a bottom-side spring pad 48, a one-side plate-shaped guide convex part 49 that extends in parallel from both side edges in the width direction of the spring pad 48 and has a rounded tip. The convex portion 50 is provided and integrally formed into a channel shape in which an engaging concave portion 51 is formed on the inner side. The spring abutting portion 48 corresponds to the spring receiving recess 42a of the bottom lid 42 of the guide case 38, and is provided with a spring insertion recess 48a at the center of the outer surface opposite to the engaging recess 51 side. The pressing convex portion 50 is formed by extending from the spring abutting portion 48 longer than the guide convex portion 49 on one side, and protrudes one step higher. In the guide convex portion 49 and the pressing convex portion 50, a concave strip portion 49 a is formed so that the convex strip portion 43 b of the guide hole 45 on the guide case 38 side can be engaged with the outer corner edge on the opposite side to the engaging concave portion 51 side. -50a is provided and stopper step part 49b * 50b is formed in the spring contact part 48 side of the concave-line part 49a * 50a.

  Accordingly, the door-side warpage prevention correction means 30 engages the protruding portion 43b with the recessed portions 49a and 50a by fitting the movable correcting tool 39 into the guide hole 45 of the guide case 38 through the bottom opening 47. One end of the spring 40 is fitted into the spring insertion recess 48a of the spring abutting portion 48, while the other end is fitted into the spring receiving recess 42a of the bottom lid 42, and then the bottom lid 42 is fixed to the lid receiving portion 43a with screws 52. assemble. Then, the door side warpage prevention correction means 30 normally urges the movable correction tool 39 in a direction protruding from the inlet opening 46 by the urging spring 40, while the stopper step portions 49b and 50b are moved to the restriction step portion 43c. At the end, as shown in FIG. 7A, the front end plate portion 50c of the pressing convex portion 50 is assembled in a state of being stopped and held at the standby position protruding from the inlet opening 46. On the other hand, when the movable correction tool 39 is pushed into the guide hole 45 against the biasing spring 40, the correction is such that the tip plate portion 50c of the pressing convex portion 50 is also accommodated in the guide hole 45 as shown in FIG.

Therefore, as shown in FIGS. 7 (A) and 7 (B), the door side warpage prevention correction means 30 places the movable correction tool 39 in the guide hole 45 of the guide case 38 and the tip plate of the pressing convex portion 50. The portion 50c is housed so as to be able to protrude and retract from the entrance opening 46.

  By the way, the illustrated hinged door D is a wooden and long panel-shaped indoor door, so if there is a difference in temperature and humidity between the indoor side and the outside of the hinged door D, bow warp deformation tends to occur. Since the temperature is high and the air is dry and the outside temperature is low and the humidity is high, the hinged door D has an intermediate portion between the upper and lower hinges P1 and P2 in the direction of the arrow X as shown by the chain line in FIG. It tends to cause convex bow warpage deformation.

  Therefore, the above-described warpage prevention correction device R having the component structure is attached to the upper and lower corner portions 11a and 11b of the door frame A using the pivot hinge P in order to prevent the warp deformation of the hinged door D. The hinged door D suspended in a pivotable manner is connected to the door frame A. In that case, as shown in FIGS. 1 and 2, the warp preventing device R is assembled with frame side warp preventing correcting means 25 on the end face 21 of the vertical frame 11 at an intermediate position between the upper and lower pivot hinges P1, P2. The door side warpage prevention correction means 30 is assembled to the suspension side end face 22 of the hinged door D so as to face the side warpage prevention correction means 25. In addition, on the suspension side end face 22 of the hinged door D, an attachment recess is drilled in a rice bowl type in accordance with the outer shape of the guide part 43 of the guide case 38 at the assembly position of the door side warp prevention correction means 30. (Not shown).

  When the frame-side warp preventing / correcting means 25 is assembled to the end surface 21 of the vertical frame 11 in the warp preventing / correcting instrument R, the mounting plate 23 is attached to the end surface 21 of the vertical frame 11 as shown in FIGS. 59, the flange 31 of the fixed corrector 24 is attached to the mounting plate 23 in a direction in which both side surfaces 35a and 35b of the guide convex portion 35 of the protrusion 32 are aligned with both side surfaces 55 and 56 of the vertical frame 11. The fixing screw 24 is temporarily fixed to the end face 21 of the vertical frame 11 by passing the set screw 37 through the elongated hole 33 and the screw hole 27. In other words, the mounting position of the fixing corrector 24 superimposed on the mounting plate 23 is set in the hole length direction along the elongated hole 33, that is, before and after the width direction of the vertical frame end surface 21 indicated by the arrow in FIG. Once attached to the vertical frame end face 21 so that the movement can be adjusted by shifting

  On the other hand, as shown in FIG. 7 (A), the door-side warpage prevention correction means 30 refers to the pressing convex portion 50 of the movable correction tool 39 as the side on which the hinged door D warps convexly in the arrow X direction at the intermediate portion. The rice bowl-shaped guide portion 43 of the guide case 38 is fitted into the mounting recess of the suspension side end face 22 and the attachment flange portion 44 is fixed with a wood screw 60, as shown in FIG. The side end face 22 is assembled. Thereafter, when the hinged door D is turned and closed in the closing direction as shown in FIGS. 10 (A) and 10 (B), the protrusion 32 of the fixed corrector 24 in the temporarily fixed state is engaged with the movable corrector 39. In consideration of the shape and amount of warp deformation of the hinged door D so that the state of engagement with the mating recess 51 is optimal, the fixing corrector 24 is attached to the mounting plate 23 shown in FIG. On the other hand, after moving and adjusting to the optimum mounting position along the long hole 33, the main fastening is performed. That is, while the hinged door D is rotated without being warped and deformed, as shown in FIG. 10A, the protrusion 32 of the fixed corrector 24 is engaged with the engaging recess 51 of the movable corrector 39 with a margin. 10B, in the fully closed state shown in FIG. 10B, an optimal state in which the inner surface of the pressing convex portion 50 of the movable correction tool 39 abuts and engages with the indoor side surface 35a of the guide convex portion 35 of the protrusion 32. Then, the fixing corrector 24 is moved and adjusted and fixed.

  In the illustrated anti-warpage corrector R, the anti-slip 34 / is formed by arranging a large number of parallel straight notches in the plate width direction on both the flange 31 of the fixed corrector 24 and the mating surfaces 31a of the mounting plate 23. 29, when the fixed corrector 24 is moved and adjusted in the longitudinal direction of the end face 11 of the vertical frame, the fixed corrector 24 is easily and accurately positioned at the optimal mounting position while suppressing excessive movement. Can do. On the other hand, once the fixing corrector 24 is fixed at a predetermined mounting position, the fixing corrector 24 can be firmly fixed without shifting due to the meshing of the parallel notches. Accordingly, the warp prevention device R shown in the figure does not cause the appearance of the component parts to protrude between the hanging side of the hinged door D and the right vertical frame 11 of the door frame A, and corrects the frame side warp prevention. The means 25 and the door side warp prevention correcting means 30 are assembled to the vertical frame end face 21 and the suspension base end face 22 of the mating surfaces, respectively, and the mounting is finished at the intermediate position between the upper and lower pivot hinges P1 and P2.

  9B, when the hinged door D is in the fully closed state, the protrusion 32 of the fixed corrector 24 has the protrusion 32 of the fixed corrector 24 at an intermediate position between the upper and lower pivot hinges P1 and P2, as shown in FIG. The hinged door D is engaged with the engaging recess 51 of the movable corrector 39 to connect the rigid door frame A to the rigid door frame A, which may cause a difference in temperature and humidity between the indoor side and the outside of the hinged door D over time. Even if there is, the hinged door D is forcibly prevented from warping and deforming.

  In the illustrated example, while the hinged door D is in the closed state, the hinged door D is connected to the door frame A with the illustrated anti-warp correction device R, so that it is forcibly restricted from deforming in a bowed shape. As shown in FIG. 11, when the hinged door D is opened and the engagement 32 of the frame-side fixed correction tool 24 and the engagement recess 51 of the door-side movable correction tool 39 are disengaged, the forced warpage restriction is released at once. As a result of the reaction, the hinged door D is greatly warped and deformed. At this time, in the door side warpage prevention correction means 30, the movable correction tool 39 is held at the standby position where the tip plate portion 50 c of the pressing convex portion 50 of the door side movable correction tool 39 protrudes from the guide hole 45. It is in.

  However, when the opening door D is opened, when the opening door D deformed into an arcuate shape shown in FIG. 8 is rotated in the closing direction as shown in FIG. The pressing convex portion 50 of the door-side movable correction tool 39 at the position is in sliding contact with the inclined indoor side surface 35a of the guide convex portion 35 of the protrusion 32 of the frame-side fixed correction device 24, and the door side warp at the inclined side surface 35a. The guide protrusion 35 is guided so that the prevention correction means 30 does not collide with the frame side warpage prevention correction means 25, and the protrusion 32 is engaged with the engagement recess 51. Then, as shown in FIG. 12B, the pressing convex portion 50 of the door-side movable correction tool 39 presses against the pressing portion 36 of the frame-side protrusion 32, and then the hinged door D rotates and closes. Accordingly, the pressing convex portion 50 of the fixed protrusion 32 is gradually pressed strongly in the direction in which the warp deformation of the hinged door D is corrected, that is, in the Y direction opposite to the warp deformation direction X of the hinged door D. However, the frame-side protrusion 32 engages with the engagement recess 51 on the door side, and as shown in FIG. 12C, the hinged door D is connected to the rigid door frame A, and the hinged door D is closed in a warped deformation restricted state. Put it in a state.

  Therefore, in the warp preventing correction tool R of the present invention, even if the hinged door D is warped and deformed each time it is opened, as the hinged door D rotates and closes in the closing direction, the pressing portion of the protrusion 32 of the frame-side fixed corrector 24 is pressed. In 36, the pressing convex portion 50 of the door-side movable correction tool 39 is gradually pressed strongly in the direction in which the warp deformation of the door D in the Y direction opposite to the warp deformation direction X is corrected, so that the door D is opened at the time of opening. The warp deformation that occurs is corrected in advance while closing the hinged door D.

  As a result, in the warp prevention correction instrument R of the present invention, since the hinged door D is opened, even if the warped deformation that has been suppressed at the time of closing occurs in the hinged door D, the warp deformed while closing the hinged door D each time. Since the projection 32 of the fixed corrector 24 on the frame side is engaged with the engaging recess 51 of the movable corrector 39 on the door side after the correction is made in advance, the hinged door D is connected to the door frame A, so that the frame side warpage is prevented. The door-side warpage prevention correction means 30 collides with the straightening means 25 and the hinged door D cannot be closed, and the opening and closing of the hinged door D is hindered. It is possible to prevent the occurrence of a problem that it is impossible to exhibit the above.

  By the way, in the above-mentioned illustrated embodiment, the movable correction tool 39 of the door side warpage prevention correction means 30 projects the guide convex portion 49 on one side of the spring abutting portion 48 (outside of the door at the time of installation), while the others. In consideration of the warp deformation direction X of the hinged door D on the side (the indoor side when installed), a pressing convex portion 50 that presses with the projection 32 on the frame side and corrects the warp deformation of the hinged door D is projected. However, the warp prevention straightening device for hinged doors of the present invention is not limited thereto, and the pressing convex portion protrudes on one side of the spring pad portion according to the warp deformation direction and shape generated in various hinged doors, or It does not exclude projecting on both sides.

  In the illustrated embodiment described above, the hinged door D is made of wood. However, the hinged anti-warpage corrector for the hinged door of the present invention is not limited to the case where the material of the hinged door is made of wood. Needless to say, the present invention can be applied to all hinged doors made of a material that has a room to generate the above.
