Moreover, the housing | casing 31 does not necessarily need to be comprised by the main body 31a and the cover part 31b.

  The 1st axial part 32 is a member which comprises a part of rotating shaft of an opening / closing door, when an opening / closing door is attached. As shown in FIGS. 3 and 7, the first shaft portion 32 is a substantially cylindrical rod-shaped member. As shown in FIG. 1 and FIG. 5, the first shaft portion 32 is inserted into a bearing portion B that rotatably supports the first shaft portion 32. In this embodiment, the bearing portion B is shown as a plate-like bearing member that is detachably attached to a structure such as a ceiling or a floor surface. A hole may be formed, or a hole formed in a door frame to which the open / close door 2 is attached. Moreover, you may embed the bearing part B in attachment places, such as a door frame and a floor surface, so that the surface of the bearing part B may become substantially the same surface as the surfaces of attachment places, such as a door frame and a floor surface. In the present embodiment, as shown in FIG. 8, the bearing portion B includes a bearing hole Ba into which the first shaft portion 32 is inserted and a plurality of screw holes H5 into which screws are inserted across the bearing hole Ba. , H6 and H7 are provided. Some of the plurality of screw holes H5, H6, and H7 (two screw holes H6 and H7 in this embodiment) are formed as long holes, and a screw is inserted (a state where the screw is not completely screwed) Thus, the position of the bearing hole Ba (for example, the position in the left-right direction in FIG. 1) can be adjusted by sliding the bearing portion B left and right in FIG. 8 with respect to the screw.

  In the present embodiment, as shown in FIG. 8, the bearing portion B includes a base member Bb that is attached to an attachment location such as a door frame and a floor surface, and a shaft that is provided in the base member Bb and in which a bearing hole Ba is formed. And an insertion portion Bc. The material of the base member Bb is not particularly limited, but in the present embodiment, the base member Bb is formed as a metal plate. The shaft insertion portion Bc may be formed integrally with the base member Bb. However, in this embodiment, the shaft insertion portion Bc is provided separately from the base member Bb and is configured to be attached to the base member Bb. Specifically, the engagement claw Bg (see FIG. 15) provided in the shaft insertion portion Bc engages with the engagement hole Bd provided in the base member Bb, so that the shaft insertion portion Bc becomes the base member Bb. Attached to. In this embodiment, as shown in FIG. 8, the shaft insertion portion Bc includes an annular portion in which a bearing hole Ba into which the first shaft portion 32 can be inserted is formed, and an engaging claw Bg ( 15). The material of the shaft insertion portion Bc is not particularly limited, but can be made of resin, for example. For example, when the resin-made shaft insertion portion Bc is configured to be attached to the metal base member Bb, the first shaft portion 32 is secured when the door 2 is rotated while securing sufficient strength as the base member Bb. Is easy to rotate smoothly, and sliding noise between the first shaft portion 32 and the shaft insertion portion Bc is also reduced.

  In this embodiment, the shaft insertion portion Bc is provided so as to protrude from the surface of the base member Bb, but the surface of the shaft insertion portion Bc (the surface facing the door 2) is the door of the bearing portion B. 2 may be provided so as not to protrude with respect to the surface facing 2 (the surface of the base member Bb in FIG. 8). In this case, as will be described later, when the first shaft portion 32 is protruded to be inserted into the bearing hole Ba of the bearing portion B, the position of the protruded first shaft portion 32 is displaced from the position of the bearing hole Ba. Even if it has occurred, the first shaft portion 32 can be easily inserted into the bearing hole Ba. Specifically, when the first shaft portion 32 protrudes out of the position of the bearing hole Ba, for example, the first shaft portion is formed on a surface of the bearing portion B facing the open / close door 2 such as the surface of the base member Bb. The tip of 32 abuts. Thereafter, the tip of the first shaft portion 32 can be slid on the surface of the base member Bb and inserted into the bearing hole Ba. Therefore, when the position of the first shaft portion 32 is shifted and protrudes, it is not necessary to return the first shaft portion 32 to the immersive state again, and the installation work of the open / close door 2 at the site is facilitated.

  The structure for preventing the surface of the shaft insertion portion Bc from protruding relative to the surface of the bearing portion B facing the open / close door 2 is not particularly limited. For example, as shown in FIG. It can be set as the structure where cover member Be which covers base member Bb was attached. The structure in which the surface of the shaft insertion portion Bc does not protrude from the surface of the bearing portion B facing the door 2 is such that the shaft insertion portion Bc does not protrude from the surface of the base member Bb. A recess provided at such a depth may be provided, and the shaft insertion portion Bc may be fitted into the recess. The cover member Be shown in FIG. 14 covers the base member Bb, and is attached to the base member Bb by an engaging portion (not shown) such as a claw that engages with the base member Bb. The cover member Be can be attached by, for example, engaging the base member Bb, but the method of attaching the cover member Be to the base member Bb is not particularly limited.

  As shown in FIG. 14, the cover member Be has an opening Bf at a position corresponding to the position where the shaft insertion portion Bc is provided. In the present embodiment, the cover member Be covers the base member Bb so that the bearing hole Ba is exposed, and covers a plurality of screw holes H5, H6, and H7 provided in the base member Bb. For this reason, the screw holes H5, H6, H7 are not exposed, and careless operation of the screw holes H5, H6, H7 is prevented, and the appearance is also improved.

  The opening Bf is a substantially circular opening as shown in FIG. 14, and is formed such that the opening edge of the opening Bf is located inside the outer periphery of the annular shaft insertion portion Bc. In this case, when the first shaft portion 32 protrudes out of the position of the bearing hole Ba, for example, the surface of the cover portion Be, such as the surface of the cover portion Be, the surface of the first shaft portion 32 that faces the door 2 is opened. The tip contacts. Thereafter, the tip end of the first shaft portion 32 can be slid on the surface of the cover member Be and inserted into the bearing hole Ba. Therefore, when the position of the first shaft portion 32 is shifted and protrudes, it is not necessary to return the first shaft portion 32 to the immersive state again, and the installation work of the open / close door 2 at the site is facilitated.

  Further, since the opening Bf is formed so that the opening edge of the opening Bf is positioned inside the outer periphery of the annular shaft insertion part Bc, for example, the engagement claw Bg of the shaft insertion part Bc is Even if it is broken, it is possible to prevent the shaft insertion portion Bc from falling off the base member Bb.

  Instead of the structure described above, the shaft insertion portion Bc is formed with a tapered surface provided between the outer periphery of the shaft insertion portion Bc and the bearing hole Ba, and the first shaft protrudes out of the bearing hole Ba. You may comprise so that the part 32 may get over the taper surface of the shaft insertion part Bc, and it may be inserted in the bearing hole Ba.

  Since the first shaft portion 32 is inserted into the bearing hole Ba of the bearing portion B and rotates, in this embodiment, the tip end portion 32a of the first shaft portion 32 is curved as shown in FIG. It is formed in a convex shape and reduces rotational resistance when the tip end portion 32a of the first shaft portion 32 comes into contact with the bearing hole Ba.

Moreover, since the 2nd axial part 42 can be set as the structure similar to the 1st axial part 32, the description is abbreviate | omitted. The second housing 41 may be configured differently from the housing 31, and the second shaft portion 42 may be configured differently from the first shaft portion 32. The bearing portion into which the second shaft portion 42 is inserted can be the same as the bearing portion of the first shaft portion 32.

  As shown in FIGS. 10 to 12, the second shaft support portion 4 is connected to the base end side of the second shaft portion 42 and is provided so as to be movable in the axis X direction inside the second housing 41. The second moving member 5 and the second casing 41 of the second shaft portion 42 are moved by moving the second moving member 5 in the axis X direction by an operation from the outside of the second moving member 5 and the second casing 41. The protrusion amount adjustment part 6 which can adjust the protrusion amount from is provided. The height of the open / close door 2 can be easily adjusted by adjusting the amount of protrusion of the second shaft portion 42 by the protrusion amount adjusting portion 6.

  In the present embodiment, as shown in FIGS. 10 to 12, the protrusion amount adjustment unit 6 is provided on the second casing 41 in a direction substantially perpendicular to the axis X direction (parallel to the insertion direction Y described above). The screw member 61 having the male screw portion 61a, which is rotatably held in the inserted state, is screwed with the male screw portion 61a, and the screw member 61 moves along the screw member 61 by rotating on the spot. And a screwing member 62. As shown in FIGS. 10 to 12, the screw member 61 is configured to be able to rotate on the spot through the main body portion 41 a of the second housing 41. Specifically, the screw member 61 is inserted from a screw member insertion hole H8 provided in the main body portion 41a, and an E-ring E is fitted on the distal end side of the screw member 61 so that the screw member 61 extends in the longitudinal direction. Restricts movement.

  In this embodiment, as shown in FIG. 10, the screwing member 62 is a block-like member having a female screw part 62 b into which the male screw part 61 a is screwed. From the outer surface of the screwing member 62, the screw member And a projecting portion 62a projecting in a direction perpendicular to the longitudinal direction of 61 and the direction of the axis X. In the present embodiment, the protruding portion 62a is shown as a shaft-like member inserted into the through hole 62c of the screwing member 62. However, the protruding portion 62a has the screwing member 62 itself and the protruding portion on the outer surface. You may process so that 62a may be formed.

Then, as the projecting portion 62a moves along the screw member 61, the slit portion SL that contacts the outer periphery of the projecting portion 62a is applied with a force that moves in the axis X direction from the projecting portion 62a, and the second moving member. 5 moves along the direction of the axis X. Accordingly, the second shaft portion 42 is configured to be able to appear and retract from the second housing 41. The protrusion amount adjustment unit 6 is not limited to the illustrated structure, and may have another structure as long as the second shaft part 42 can be moved in the axis X direction. For example, by using a gear mechanism such as a rack gear and a pinion gear, the rotational force from the outside of the second housing 41 is replaced with the linear motion of the second shaft portion 42, and the amount of protrusion of the second shaft portion 42 is increased. You can adjust it.

  Next, the effect of the opening / closing door mounting structure 1 of the present embodiment will be described. In the following description, the case where the door 2 having the rotation axis X extending in the vertical direction is mounted between the ceiling and the floor will be described. However, the door mounting structure 1 of the present invention is limited to the following contents. It is not something. In addition, the order of operations in the following description is merely an example, and is not limited to the following order.

  First, the opening / closing door 2 is prepared in which the first shaft support portion 3 is provided on the top end side of the opening / closing door 2 and the second support portion 4 is provided on the bottom end side of the opening / closing door 2. Then, the bearing portion B is screwed to each of the ceiling and the floor surface where the first shaft portion 32 of the first shaft support portion 3 and the second shaft portion 42 of the second shaft support portion 4 protrude. Fix it.

  In the prepared opening / closing door 2, as shown in FIG. 5, when the holder 35 is not inserted into the casing 31, the holder 35 is inserted into the casing 31, and as shown in FIG. The first shaft portion 32 of the first shaft support portion 3 is in an immersive state in which the first shaft portion 32 is retracted downward. In this case, as described above, the insertion portion 35a of the holder 35 is inserted into the insertion hole H2 of the housing 31 from the state of FIG. When the insertion portion 35a is inserted into the insertion hole H2, the tip T side of the insertion portion 35a comes into contact with the inclined contact portion 33b as shown in FIG. When the insertion portion 35a is further inserted as it is, the moving member 33 receives a force from the tip T of the insertion portion 35a, and a component force of the pressing force from the tip T is applied downward in FIG. It moves in the immersion direction against the urging force of the urging member 34. When the insertion portion 35a is further inserted from the state of FIG. 6, the tip T of the insertion portion 35a goes over the contact portion 33b and rides on the engagement portion 33c as shown in FIG. And the linear part of the insertion part 35a and the engaging part 33c engage, the moving member 33 is pushed down, and the 1st axial part 32 is hold | maintained in an immersion state.

  Next, the second shaft portion 42 of the second shaft support portion 4 is protruded from the second housing 41. For example, from the state shown in FIG. 11, the screw member 61 is rotated as described above, the second shaft portion 42 is lowered as shown in FIG. 12, and the second shaft portion 42 is moved to the second position. Project from the housing 41.

  When the second shaft portion 42 of the second shaft support portion 4 protrudes from the second housing 41, the second shaft portion 42 is inserted into the bearing hole Ba of the bearing portion B provided on the floor surface side. Next, in order to insert the first shaft portion 32 into the bearing hole Ba of the bearing portion B on the ceiling side, the first shaft portion 32 in the immersive state is protruded. Specifically, the first shaft portion 32 of the first shaft support portion 3 is aligned with the position of the bearing hole Ba of the bearing portion B on the ceiling side as shown in FIG. Thereafter, the holder 35 is removed from the housing 31. When the holder 35 is removed from the housing 31 in the horizontal direction, the insertion portion 35a of the holder 35 is removed from the insertion hole H2. When the insertion portion 35 a is removed, the moving member 33 is pressed by the biasing member 34 in the protruding direction of the first shaft portion 32, so that the first shaft portion 32 protrudes from the housing 31. More specifically, when the insertion portion 35a is removed from the insertion hole H2, the moving member 33 is pressed against the urging force of the urging member 34 between the engagement portion 33c and the insertion portion 35a. The engagement in the axis X direction is released. As a result, the moving member 33 can move, and the moving member 33 moves upward by the urging force of the urging member 34. When the moving member 33 moves upward, the first shaft portion 32 moves upward together with the moving member 33 and protrudes from the upper end surface of the open / close door 2 as shown in FIG. When the first shaft portion 32 protrudes from the upper end surface of the door 2, the first shaft portion 32 is inserted into the bearing hole Ba of the bearing portion B, and the attachment of the door 2 is completed.

  Thus, according to the opening / closing door mounting structure 1 of the present embodiment, the first shaft portion 32 protrudes from the housing 31 and the mounting to the bearing portion B is completed simply by removing the holder 35. Therefore, the attachment work of the opening / closing door 2 becomes very easy. For example, it is very difficult to turn the screw to operate the shaft part while holding the heavy opening / closing door 2, but according to this embodiment, the opening / closing door 2 is supported by one hand. However, the opening / closing door 2 can be easily attached by removing the holding tool 35 with the opposite hand. In addition, even when work at a high place such as the upper end side of the open / close door 2 is required, the attachment of the open / close door 2 can be completed simply by removing the holder 35. The work can be completed quickly, and the safety of the work can be improved.

  In the present embodiment, the opening / closing door 2 can be inserted between the ceiling and the floor surface in a state where the first shaft portion 32 is immersed by the holder 35. Therefore, for example, when the upper and lower doors are inserted between the ceiling and the floor surface, such as those in which the upper shaft portion (which does not have the retainer 35) is simply biased in the protruding direction by a spring, A complicated operation of inserting the upper shaft portion while pressing the shaft portion in the immersion direction is not necessary. The shaft portion simply biased in the protruding direction by the spring is difficult to remove once the shaft portion is inserted into the bearing portion. However, in the present embodiment, the first shaft portion is held by the holder 35. Since 32 can be easily moved to the immersive state, it is easy to remove. Furthermore, since the opening / closing door 2 can be attached in a state in which the first shaft portion 32 is immersed, the gap between the upper end of the opening / closing door 2 and the ceiling can be reduced.

  In addition, after the opening / closing door 2 is once attached, for example, the positions of the upper and lower bearing portions B may be shifted, and the opening / closing door 2 may not be opened and closed successfully. In such a case, once the door 2 is removed and the position of the bearing B is slid as described above, the position of the bearing B can be adjusted and the position of the door 2 can be adjusted. it can. Even when the opening / closing door 2 needs to be removed due to such a positional shift of the opening / closing door 2 or other factors, the opening / closing door 2 can be easily removed by inserting the holder 35 into the housing 31. be able to.

  In addition, the first shaft portion 32 does not move to the immersive position unless the holder 35 as a dedicated jig is provided. Therefore, it is possible to prevent an accident in which the first shaft portion 32 is unexpectedly moved to the immersive position and the open / close door 2 is collapsed in a general home. In the present embodiment, the opening / closing door 2 is not joined to the door frame with a flat hinge or the like and is pivotally supported by the first shaft portion 32 and the second shaft portion 42. In the end surface of the rotary shaft X side of 2, the generation of a gap between hands and feet is prevented, and a safe open / close door structure can be obtained. Furthermore, since the opening / closing door 2 can be attached simply by fixing the first shaft portion 32 and the second shaft portion 42 to the ceiling and the floor surface, a door frame is unnecessary. Therefore, the number of parts can be reduced, and when the opening / closing door 2 is newly provided by renovation of the room, etc., if there is only a ceiling and a floor surface, the opening / closing door 2 can be installed at an arbitrary place only by providing the bearing portion B. Can be provided.
