The steady-rest structure according to the present invention includes a steady-state body that shifts and guides the lower part of the door panel, and an adjustment structure for adjusting the front-rear position thereof, and is applied to suspension doors such as sliding doors and folding doors.

  An anti-sway structure having an anti-sway roller adjustment structure is known, for example, from Patent Document 1. There, a U-shaped frame-shaped base fixed to the floor, a U-shaped frame-shaped bracket supported by the base, a roller pivotally supported by the bracket, and an adjustment for adjusting the front and rear positions of the roller The anti-rest structure is composed of the structure. A lateral fulcrum pin is fixed to the standing wall on one side of the base, and the hanging wall on one side of the bracket is supported by the fulcrum pin so as to be movable back and forth. Further, a screw hole is formed in the standing wall on the other side of the base, and a long hole in the front-rear direction is formed in the hanging wall on the other side of the bracket.

Japanese Patent Laying-Open No. 2003-293657 (paragraph number 0023, FIGS. 8 to 11) Japanese Utility Model Publication No. 03-023583 (page 7, line 1-19, FIG. 1)

  According to the swing prevention structure of Patent Document 1, the roller position can be optimized by adjusting the front-rear position of the bracket corresponding to the guide groove of the door panel. However, the roller position is adjusted by tilting the bracket back and forth around the fulcrum pin fixed to one side of the base, so that when the external force acts on the door panel, the tilting moment acts on the roller. Cannot be avoided, and the roller position may shift back and forth.

  In that respect, in the anti-seismic structure of Patent Document 2, since the fastening seat located near the shaft-like guide is fastened to the floor surface with screws (wood screws), even when external force in the front-rear direction acts on the door panel, the guide and The position of the substrate can be well prevented from shifting back and forth. However, after adjusting the position of the board in the front-rear direction, the screw inserted through the fastening seat is screwed into the floor surface through the long hole of the mounting seat plate to fix the board. If it is screwed, it becomes difficult to adjust the position of the substrate again. This is because even if the screw screwed into the floor surface is removed and the position of the board is finely adjusted, the screw hole is already formed in the floor surface, so the screw screwed in after the position adjustment has shifted to the screw hole side. This is because the substrate and the guide cannot be fixed at an appropriately adjusted fine position. For this reason, the guide should be used properly when the suspension structure is fastened to the wrong position during construction of the hanging door, or when the position of the guide needs to be readjusted in response to warpage deformation of the door panel during long-term use. It becomes difficult to fix in a proper position. In addition, since the fastening seat is formed in a cantilever shape from the substrate, the fastening seat is not strong enough. Therefore, when the screw is screwed with a tool with a large fastening torque such as an electric screwdriver, the fastening seat is There is a risk of being bent.

The object of the present invention is to make it easier and more repetitive to adjust the position of the anti-vibration body, so that the position of the anti-vibration body can be used not only during construction but also when the door panel is warped. Is to provide a steady rest structure for a hanging door that can properly shift and guide the door panel.
An object of the present invention is to firmly fix and hold a position-adjusted anti-vibration body so that the anti-vibration body can be prevented from being displaced due to an external force acting on the door panel in the front-rear direction. An object of the present invention is to provide a suspension structure for a hanging door that is excellent in fastening strength capable of properly guiding the movement.

  The suspension structure for a hanging door according to the present invention includes a guide base 20 fastened to a floor surface, an adjustment base 21 guided by the guide base 20 so as to be slidable back and forth, and a vibration fixed to the upper surface of the adjustment base 21. A stop body 22 is provided. As shown in FIG. 4, the guide base 20 includes a guide wall 24 having an adjustment groove 28 that allows the anti-vibration body 22 to move back and forth, a fastening seat 26 provided on one side of the guide wall 24, and a guide wall 24. A clamp piece 27 provided on the other side and a screw insertion hole 33 formed in a screw seat 32 at the protruding end of the clamp piece 27 are provided. The adjustment base 21 is disposed on the lower surface of the guide wall 24 of the guide base 20 and is guided so as to be slidable back and forth between the guide base 20 and the floor surface. A screw long hole 39 made of a long hole in the front-rear direction is formed on the base surface of the adjustment base 21 facing the fastening seat 26. As shown in FIG. 1, the guide wall 24 and the clamp piece 27 of the guide base 20 are in close contact with the adjustment base 21 in a state where the screw 50 is screwed into the floor surface through the screw insertion hole 33 and the screw long hole 39. The adjustment base 21 is fixed so that it cannot move back and forth.

  The clamp piece 27 of the guide base 20 is formed in an upper protruding shape, and a screw seat 32 is formed at the protruding end. The protruding ends 32 a of the clamp pieces 27 before being fastened with the screws 50 are lifted away from the upper surface of the adjustment base 21. In a state where the screw 50 is screwed into the floor surface, the clamp piece 27 is elastically deformed, and the projecting end 32a is brought into close contact with the adjustment base 21, and the adjustment base 21 is pressed and fixed so as not to move back and forth.

  As shown in FIG. 1, the clamp piece 27 is formed in an inverted V shape by a base end wall 31 that is continuously inclined upward to the guide wall 24 and a screw seat 32 that is continuously inclined downward to the base end wall 31. To do. As a result, the operating head of the screw 50 inserted through the screw insertion hole 33 can be tightened and loosened from above with the fastening tool T.

  The adjustment base 21 includes a base main wall 35 that supports the steadying body 22, a slide piece 36 that protrudes from one side of the base main wall 35, and a slide seat 37 that is provided at the other side of the base main wall 35. And a screw slot 39 in the front-rear direction is formed in the vicinity of the sliding seat 37. The slide piece 36 is supported by the peripheral wall of the slide groove 29 provided in the guide base 20 and simultaneously the slide seat 37 is supported by the floor surface. As a result, the adjustment base 21 is guided and supported by the guide base 20 and the floor so as to be slidable back and forth.

  The anti-vibration body 22 includes an anti-vibration roller 42 that shifts and guides the anti-vibration groove 5a of the door panel 1 and a roller shaft 43 that rotatably supports the anti-vibration roller 42. The roller shaft 43 includes an adjustment shaft portion 46 that is supported by the adjustment groove 28 so as to be freely slidable back and forth, and a flange portion 45 and a caulking shaft portion 47 provided above and below the adjustment shaft portion 46. The adjustment base 21 disposed on the lower surface of the guide wall 24 is engaged with the caulking shaft portion 47, and the shaft end of the coaxial portion 47 is caulked to separate the guide base 20, the adjustment base 21, and the anti-vibration body 22 from each other. Integrate impossible.

  In the present invention, the guide base 20 fastened to the floor surface, the adjustment base 21, and the steadying body 22 fixed to the upper surface of the adjustment base 21 constitute a steady-rest structure, and the adjustment base 21 in use is the The guide base 20 and the floor surface are guided so as to be able to slide back and forth. Further, by fastening the clamp piece 27 of the guide base 20 fastened to the floor surface with a screw 50, the guide wall 24 and the clamp piece 27 can be brought into close contact with the adjustment base 21, and the adjustment base 21 can be fixed so as not to move back and forth. I did it. In this way, when the adjustment base 21 is pressed and fixed by the guide wall 24 and the clamp piece 27, the change in the fastening position of the screw 50 according to the difference in the adjustment position of the adjustment base 21 is eliminated, and the floor of the screw 50 is removed. The fastening position with respect to the surface can be fixed. Therefore, when adjusting the position of the anti-vibration body 22, the screw 50 is loosened to release the restraint by the guide wall 24 and the clamp piece 27, the adjustment base 21 is adjusted and moved, and the screw 50 is screwed again. That's fine. Therefore, according to the steady rest structure according to the present invention, the position adjustment of the steady rest 22 can be performed more easily and repeatedly as many times as possible, and when the door panel 1 is warped and deformed during construction. In addition, the door panel 1 can always be properly shifted and guided by readjusting the position of the anti-vibration body 22.

  In a state where the screw 50 is screwed into the floor surface, the protruding end 32a of the clamp piece 27 formed in an upper protruding shape is brought into close contact with the adjustment base 21, and when the base 21 is pressed and fixed so as not to move back and forth, the adjustment base 21 is clamped. 27 can press more reliably. When the clamping piece 27 comes into contact with the adjustment base 21 in response to the fastening force of the screw 50, the projecting end 32a comes into contact with the adjustment base 21 prior to the other part, and the clamping piece 27 is connected with the screw 50. This is because the base 21 is pressed in a direction approaching the adjustment base 21 and is firmly pressed against the floor surface to be brought into close contact therewith. In addition, when the screw 50 is screwed into the floor surface, the clamp piece 27 is elastically deformed, and the deformation stress always acts on the screw 50. Therefore, the screw 50 can be loosened using the deformation stress of the clamp piece 27. .

  When the clamp piece 27 is formed in an inverted V shape with the base end wall 31 inclined upward and the screw seat 32 inclined downward, the screw 50 screwed into the floor surface is oriented in a direction substantially orthogonal to the screw seat 32 inclined downward. Can be oriented. Therefore, when the screw 50 inserted through the screw seat 32 is screwed into the floor surface, it is not necessary to remove the door panel 1 from the guide rail 3, and the operating head of the screw 50 can be easily and accurately tilted from above with the fastening tool T. Can be tightened. Further, according to the clamp piece 27 formed in the inverted V shape by the base end wall 31 and the screw seat 32, the base end 31a and the projecting end 32a of the clamp piece 27 are received in a triangular shape by the adjustment base 21, so that the clamp The structural strength of the piece 27 can be improved. Therefore, even when the screw 50 is screwed into the floor with a tool having a large fastening torque such as an electric screwdriver, the screw seat 32 can be prevented from being bent. Further, since the fastening force of the screw 50 is effectively applied to the adjustment base 21 and the position-adjusted anti-vibration body 22 can be firmly fixed and held, the external force acting in the front-rear direction acting on the door panel 1 is received. It is possible to more reliably prevent the position of the anti-vibration body 22 from being displaced, and to appropriately guide the transition of the door panel 1 over a long period of time.

  When the slide piece 36 of the adjustment base 21 is supported by the peripheral wall of the slide groove 29 of the guide base 20 and the sliding seat 37 of the adjustment base 21 is supported by the floor surface, the adjustment base 21 can be slid forward and backward in a stable state. Can support the guide. Since the adjustment base 21 is slid and guided using the floor surface, the slide structure between the adjustment base 21 and the guide base 20 can be simplified, and the cost required for manufacturing the bases 20 and 21 can be reduced. Further, since the sliding seat 37 of the adjusting base 21 is pressed against the floor surface with the clamp piece 27, the longitudinal movement of the adjusting base 21 can be more accurately regulated by the frictional resistance between the sliding seat 37 and the floor surface. . Furthermore, the adjustment structure can be thinned by reducing the total thickness of the guide base 20 and the adjustment base 21.

  When the adjustment base 21 disposed on the lower surface of the guide wall 24 is caulked at the shaft end of the caulking shaft portion 47 so that the guide base 20, the adjustment base 21, and the anti-vibration body 22 are integrated in an inseparable manner, the screw 49 -The anti-roller structure except 50 can be collected as one unit part. Accordingly, it is only necessary to position the anti-rest structure formed as a unit part and fasten it with screws 49 and 50 at the construction site, so that the labor of construction can be greatly reduced. In addition, since the guide base 20, the adjustment base 21, and the anti-vibration body 22 are integrated so as not to be separable, for example, components of plural types of anti-vibration structures having different sizes do not mix and are shipped or stored. Can be easily managed.

  In FIG. 4, the steady rest structure includes a guide base 20 fastened to the floor surface, an adjustment base 21 guided by the guide base 20 so as to freely slide back and forth, and a steady rest 22 fixed to the upper surface of the adjustment base 21. Configure. The guide base 20 and the adjustment base 21 are each formed by press forming a steel plate.

  The guide base 20 includes a rectangular guide wall 24, a step wall 25 bent continuously downward on one side edge of the guide wall 24, and a fastening seat bent sideways continuously on the step wall 25. 26 and a clamp piece 27 that is bent at the front and rear center of the other side edge of the guide wall 24 are integrally provided. In the center of the guide wall 24, an adjustment groove 28 that is long in the front-rear direction that allows the back and forth movement of the anti-vibration body 22 is formed. It is formed. Further, screw holes 30 are formed at two positions on the front and rear of the fastening seat 26. The clamp piece 27 is formed in an inverted V shape by a base end wall 31 that is continuously inclined upward to the guide wall 24 and a screw seat 32 that is continuously inclined downward to the base end wall 31. Is formed with a round hole-like screw insertion hole 33. The vertical height from the lower surface of the fastening seat 26 to the top of the clamp piece 27 is 5 mm.

  The adjustment base 21 includes a base main wall 35 that supports the anti-vibration body 22, a slide piece 36 that projects from the front and rear center of one side of the base main wall 35, and a slide that is provided on the other side of the base main wall 35. The seat 37 is provided integrally. The base main wall 35 is formed with a connecting hole 38 for caulking and fixing the steady rest 22. The sliding seat 37 is bent so as to be stepped down from the base main wall 35, and a rectangular screw long hole 39 is formed between the base main wall 35 and the sliding seat 37 sandwiching the stepped portion. It is formed.

  The anti-vibration body 22 includes a plastic anti-vibration roller 42 that shifts and guides the anti-vibration rail 5 and a roller shaft 43 that rotatably supports the anti-vibration roller 42. The roller shaft 43 includes, in order from the upper side, an upper shaft portion 44 that supports the anti-roll roller 42, a flange portion 45, an adjustment shaft portion 46 that is supported by the previous adjustment groove 28 so that only front and rear sliding is freely possible, and an adjustment shaft portion. A caulking shaft portion 47 provided at a lower portion of 46 is integrally provided. The anti-roller roller 42 and the flat washer are fitted on the upper shaft portion 44, and the upper end of the upper shaft portion 44 is caulked, so that the anti-roll roller 42 is integrated with the roller shaft 43 and is rotatably supported.

  The guide base 20, the adjustment base 21, and the anti-vibration body 22 are united by placing the adjustment base 21 on the lower surface of the guide base 20 and integrating the slide piece 36 with the slide groove 29. It is partized. Specifically, as shown in FIG. 1, the adjustment shaft portion 46 of the roller shaft 43 is engaged with the adjustment groove 28 of the guide wall 24, and the caulking shaft portion 47 is engaged with the connecting hole 38 to caulk the shaft end. By processing, the former three are integrated so as not to be separated. In this state, the adjustment base 21 and the steady rest 22 can slide relative to each other within the range of the adjustment groove 28. However, since the adjustment shaft portion 46 is received by the adjustment groove 28, the adjustment base 21 and the anti-vibration body 22 do not slide relative to the left and right beyond the clearance gap of the adjustment groove 28.

  The steady structure is fixed to the floor as follows, and then the center position of the steady roller 42 is adjusted. First, the front and rear positions to be fastened with the anti-vibration structure are determined based on the guide rail 3, and the left and right positions to be fastened with the anti-vibration structure are determined based on the width dimension of the door panel 1. At the determined fastening position on the floor surface, the anti-rest structure made into a unit part is placed in a state where the adjustment base 21 is located on the lower surface, and the fastening seat 26 of the guide base 20 is positioned. In this state, the first base (screw) 49 is screwed into the floor surface through the front and rear screw holes 30 to fix the guide base 20. Next, after adjusting the front / rear position of the adjustment base 21 so that the anti-roller roller 42 is positioned approximately at the front / rear center of the guide base 20, the second screw (screw) 50 inserted through the screw insertion hole 33 of the clamp piece 27. Is screwed into the floor through the long screw holes 39. The second screw 50 at this time is screwed up to the middle of screwing.

  As described above, the adjustment base 21 when the second screw 50 is screwed into the middle position is supported by the fastening seat 26 (peripheral wall of the slide groove 29) whose slide piece 36 faces the slide groove 29, and further slides. A moving seat 37 is supported on the floor surface. That is, the adjustment base 21 is guided so as to be slidable back and forth between the guide base 20 and the floor surface, and can be moved in the front-rear direction. Further, the guide wall 24 of the guide base 20 and the base end 31 a and the protruding end 32 a of the clamp piece 27 are lifted away from the upper surface of the base main wall 35 of the adjustment base 21.

  After temporarily fixing the anti-vibration structure to the floor surface, the door panel 1 is suspended from the guide rail 3 and the anti-vibration rail 5 is engaged with the anti-vibration roller 42. As described above, the adjustment base 21 in this state is in a state in which it can move in the front-rear direction. For this reason, when the door panel 1 is opened and closed several times while being held in a vertical posture, the adjustment base 21 is moved and operated in a direction to absorb the deviation in the front-rear direction by the anti-vibration rails 5. Can be made to coincide with the center position of the guide rail 3. As described above, after the anti-roll roller 42 is positioned on the door panel 1, the adjustment base 21 is fixed so that the adjustment base 21 cannot be moved back and forth by screwing the second screw 50 to the end while the adjustment base 21 is held and fixed. At this time, since the screw seat 32 is inclined, as shown in FIG. 1, the second screw 50 is driven by an electric or manual screwdriver (fastening tool) T inserted into the anti-vibration groove 5a of the anti-vibration rail 5. The operating head can be easily screwed in from diagonally above.

  As the second screw 50 is screwed into the floor surface, the clamp piece 27 is drawn toward the floor surface and elastically deforms, and the guide wall 24 comes into close contact with the upper surface of the base main wall 35. Further, the base end 31a of the clamp piece 27 is in close contact with the upper surface of the base main wall 35, and the protruding end 32a of the clamp piece 27 is in close contact with the upper surface of the sliding seat 37, thereby pressing the adjustment base 21 to the floor surface side. As a result, the adjustment base 21 is pressed and fixed by the guide base 20 so that the slide piece 36 is in close contact with the fastening seat 26 and the slide seat 37 is in close contact with the floor surface so as not to move back and forth. Since a large frictional resistance is generated between the sliding seat 37 and the floor surface in this state, it is possible to reliably prevent the adjustment base 21 from moving back and forth due to an external force.

  When the swing roller 42 is in contact with the swing groove 5a or when the door panel 1 is warped, the second screw 50 is loosened and the adjustment base 21 is restrained by the clamp piece 27. Is released. At this time, it is not necessary to remove the second screw 50 from the floor surface, and the second screw 50 may be loosened to such an extent that the operation head is slightly separated from the screw seat 32. Since the adjustment base 21 with the second screw 50 loosened can be moved back and forth, the adjustment base 21 can be moved back and forth by opening and closing the door panel 1 several times in the same way as during construction, and the anti-roll roller The center position of 42 can be made to coincide with the center position of the swing groove 5a.

  For example, when the adjustment base 21 is stuck on the floor and is difficult to move back and forth following the opening and closing operation of the door panel 1, the adjustment base 21 is adjusted by tapping it with a tool, etc. The center position of 42 is made to coincide with the center position of the retaining groove 5a. Finally, the adjustment base 21 can be fixed so as not to move back and forth by screwing the second screw 50 back to the end. The adjustment base 21 and the anti-roll roller 42 in this embodiment can be adjusted by 2 mm from the front and rear center to the front or rear.

  In the anti-seismic structure having the above-described configuration, the clamp piece 27 of the guide base 20 fastened to the floor surface is fastened by the screw 50, and the position-adjusted adjustment base 21 is pressed and fixed by the guide wall 24 and the clamp piece 27. Therefore, the fastening position of the screw 50 does not change according to the difference in the adjustment position of the adjustment base 21, and the fastening position of the screw 50 with respect to the floor surface can be fixed. Therefore, when adjusting the position of the anti-vibration body 22, the screw 50 is loosened and the restraint by the guide wall 24 and the clamp piece 27 is released. The position adjustment of the steady rest 22 can be performed more easily and repeatedly. Accordingly, not only during construction, but also when the door panel 1 is warped and deformed, the position of the anti-vibration body 22 is readjusted so that the door panel 1 can always be properly transferred and guided.

  In the above embodiment, the clamp piece 27 is formed in an inverted V shape, but it is not necessary. The clamp piece 27 may be formed in at least an upper protruding shape, for example, an upward protruding curved shape or a quadrant formed by a vertical standing wall and an arc wall continuous with the vertical wall. In the above embodiment, the guide base 20 and the adjustment base 21 are each a press-formed product. However, it is not necessary, for example, a die-cast product or an insert-molded product with a metal plate inserted. Can be formed. If necessary, a folded wall that contacts the sliding seat 37 can be formed continuously from the protruding end 32 a of the screw seat 32. A rubber sheet having a high frictional resistance is fixed to the lower surface of the sliding seat 37 of the adjusting base 21 or a protrusion that pierces the floor surface is provided on the sliding seat 37 so that the adjusting base 21 after position adjustment moves back and forth. Can be blocked.

  The anti-vibration groove 5a does not need to be formed by embedding the anti-vibration rail 5 in the door panel 1, and the anti-vibration groove 5a can be formed directly in the door panel 1 by being recessed. The steady rest 22 does not need to have a roller structure, and may be formed in a pin shape. The slide groove 29 can be formed on the guide wall 24 side. In addition to the sliding doors described in the embodiments, the present invention can be applied to folding doors or hanging doors such as slide doors constituting double-acting doors.
