That is, the guide rail 7 is attached between the left and right vertical columns 4 and 4 where the upper edges of the door bodies Ma and Mb are located so that the upper edges of the door bodies Ma and Mb can be slidably moved to the left and right. . The pipe-shaped rail 6 and the guide rail 7 described above will be described in detail later.

  Here, the structure of the door main body M attached to the front frame 2 is shown in FIG. FIG. 2A is an explanatory diagram showing the configuration of the door main body M viewed from the inside of the greenhouse H, and FIG. 2B is the front frame 2 and the door main body M attached to the front frame 2. It is AA sectional drawing. 2B, the left side of the drawing is the inside of the greenhouse H, and the right side of the drawing is the outside of the greenhouse H.

  As shown in FIG. 3, the door body M is configured by a rectangular shape by an upper side frame 8, left and right vertical frames 9 and 9, and a lower side frame 10. Further, between the upper frame 8 and the lower frame 10, two horizontal bars 11, 11 are interposed between the left and right vertical frames 9, 9.

  In addition, on each front side surface of each frame 8, 9, 10 and the crosspiece 11 is provided with a fitting groove 14 having fitting ribs 13 and 13 that can be fitted through separately provided fitting pieces 12 as side walls, The vinyl sheet S is inserted into the fitting groove 14 while covering the front side surface of the door body M with the vinyl sheet S slightly larger than the outer shape of the door body M, and the fitting piece 12 is fitted into the fitting groove 14 from above the vinyl sheet S. To do. That is, the vinyl sheet S is stretched on the door body M so that the fitting pieces 12 are pressed and urged to the inner side walls of the fitting ribs 13 and 13.

  The lower frame 10 is a pipe-shaped rail in which rollers 15 and 15 are pivoted in the vicinity of the left and right end portions of the lower frame 10 within a base frame K having a substantially U-shaped cross section with a lower opening. 6 is configured to roll on.

  Further, horizontally rotatable upper rollers 16 and 16 are pivoted in the vicinity of both ends of the upper surface of the upper frame 8, and the upper roller 16 contacts the inner wall of the guide rail 7 that houses the upper edge of the upper frame 8. It is configured to slide.

  A door structure 1 that is slidable to the left and right is constituted by the door body M and the peripheral structure thus configured.

  Hereinafter, after describing in detail the lower part of the door structure 1 about the specific structure of each part, the upper part is explained in full detail. In addition, since the structure of the door main body M appears left-right symmetrically, it demonstrates by showing one side and abbreviate | omits description about the other suitably.

  As the pipe-shaped rail 6 according to the present embodiment, for example, an existing cylindrical steel pipe, in particular, a carbon steel pipe for machine structure is used, but it can be formed of a PVC pipe or the like, as shown in FIG. , The entrance / exit rail 6a laid at the house entrance / exit m, and the fixed rail 6b connected in a state where the ends are abutted to the left and right.

  FIG. 4 is a cross-sectional view illustrating a configuration of a portion where the door main body M (the central portion is omitted) is attached to the vertical column 4. The left side of the drawing is the inside of the greenhouse H, and the right side of the drawing is the outside of the greenhouse H. 5A is an exploded perspective view of the lower frame 10, FIG. 5B is a bottom view of the lower frame 10, and FIG. 6 is an end portion of the lower frame 10 viewed from the outside of the greenhouse H and a pipe. It is the perspective view which showed the attachment structure of the shape rail 6. FIG.

  As shown in FIGS. 4 and 5, the lower frame 10 constituting the door main body M is configured by a base frame K having a substantially U-shaped cross section with a lower opening, and is stretched on the door main body M on the base frame K. A sheet mounting portion 17 to which the vinyl sheet S can be attached is provided, and a roller 15 that can roll on the pipe-shaped rail 6 is pivoted between the U-shaped inner and outer plates 18 and 19 of the base frame K. .

  Specifically, inside the U-shaped base frame K, a drum-shaped roller 15 is screwed and fixed to a nut 21 via a support shaft 20 having a male screw portion at the tip, and is rotatably mounted. The constricted portion of the roller 15 having a shape matches the upper half arcuate surface of the pipe-shaped rail 6 so that the roller 15 can roll on the pipe-shaped rail 6. Further, the rollers 15 are arranged at two positions with respect to the base frame K, and the positions thereof are slightly inside the longitudinal ends of the base frame K.

  Further, the inner plate 18 of the base frame K extends to the side of the pipe-shaped rail 6. That is, the inner plate 18 extends downward to the arcuate portion of the lower half portion of the pipe-shaped rail 6, covers the contact portion between the pipe-shaped rail 6 and the roller 15 from the inside, and the door body M falls off to the outside. And the function of blocking the outside wind from outside as much as possible.

  Accordingly, when the roller 15 is placed on the pipe-shaped rail 6 and the pipe-shaped rail 6 is viewed from the inner plate 18 side (inside the house), at least the upper half of the pipe-shaped rail 6 is the inner plate 18. It is in a covered state. Here, the inner side plate 18 extends down to a position reaching the arcuate portion of the lower half of the pipe-shaped rail 6.

  The sheet mounting portion 17 includes a sheet mounting plate 22 erected along the base frame K on the upper surface of the base frame K, and a fitting piece 12 in which a vinyl sheet edge is separately provided on the outer surface of the mounting plate 22 (see FIG. 3). The upper and lower ribs 13a and 13a are provided so as to protrude through a predetermined interval so as to be fitted through.

  Further, as shown in FIG. 7, since the vertical frames 9 are erected at both ends of the upper surface of the base frame K, the seat mounting plate 22 is not formed in the portions as shown in FIGS. That is, the connecting portion between the base frame K and the vertical frame 9 becomes both ends of the upper surface of the base frame K.

  As shown in FIGS. 3, 4, and 7, a restriction plate 23 extending to the side of the pipe-like rail 6 is detachably attached to a predetermined portion of the outer plate 19 of the base frame K. . The restricting plate 23 is formed in a rectangular plate shape, and the upper short side central portion is bent at a substantially right angle with the longitudinal direction up and down to form a rotation preventing piece 24, and a fixing bolt is provided at a substantially central portion of the flat plate surface. Bolt insertion holes (not shown) for inserting 25 are formed. The width of the rotation preventing piece 24 is slightly narrower than the opening width of the fitting groove 14 formed in the vertical frame 9.

  The restricting plate 23 formed in this way is attached to the connecting portion between the left and right vertical frames 9 and 9 and the base frame K. Specifically, the female screw hole 26 formed in the outer plate 19 of the base frame K and the bolt insertion hole of the regulating plate 23 while the rotation preventing piece 24 is inserted and engaged in the fitting groove 14 of the vertical frame 9. Are in contact with each other so that the side surface of the outer plate 19 and the side surface of the regulating plate 23 are in contact with each other.

  In this way, the lower frame 10 is constituted by a base frame K having a substantially U-shaped cross section in the lower opening, and the pipe-shaped rail 6 can roll between the U-shaped inner and outer plates 18, 19 of the base frame K. Since the roller 15 is pivoted, the roller 15 can be pivoted while forming a part of the frame of the door body M only by the lower frame 10 without providing a separate support frame at the lower end of the door body M. Since there is no gap connecting to the inside and outside of the greenhouse H in this part, the temperature environment in the temperature-controlled greenhouse H can be stabilized.

  In addition, since it is not necessary to provide a separate support frame for pivoting the roller 15 at the lower end of the lower frame 10, the number of parts of the greenhouse H can be reduced, which is advantageous in terms of cost and the assembling property of the greenhouse H. Can also be improved.

  Further, the lower frame 10 is constituted by a base frame K having a substantially U-shaped cross section with a lower opening, and the base frame K is provided with a sheet mounting portion 17 on which a vinyl sheet S stretched on the door body M can be attached. Therefore, there is no need to separately provide the seat mounting portion 17 and the like, and the number of parts can be reduced and the assemblability of the greenhouse H can be improved.

  Further, the sheet mounting portion 17 is provided with a sheet mounting plate 22 erected along the base frame K on the upper surface of the base frame K, and a vinyl sheet S edge on the outer surface of the mounting plate 22 via a fitting piece 12 provided separately. Since the upper and lower ribs 13a and 13a are provided so as to protrude at fixed intervals so as to be fitted, the fitting pieces 12 are pressed and urged to the inner side walls of the upper and lower ribs 13a and 13a to securely hold the vinyl sheet S. Can be stretched.

  Further, since the inner plate 18 of the base frame K extends to the side of the pipe-shaped rail 6, a levitation force is generated to lift the roller 15 from the pipe-shaped rail 6 due to the positive pressure inside the greenhouse H. Even so, it is possible to prevent the roller 15 from coming off the outside of the greenhouse H.

  In addition, since the restriction plate 23 extending to the side of the pipe-like rail 6 is detachably attached to a predetermined position of the outer plate 19 of the base frame K, the inside of the greenhouse H without the restriction plate 23 being attached. The door main body M can be attached between the guide rail 7 and the pipe-shaped rail 6 from the outside, and then, by attaching the regulating plate 23, the contact surface between the pipe-shaped rail 6 and the roller 15 circumferential surface is exposed from the outside. Even if the outside wind enters and a levitation force that lifts the roller 15 from the pipe-shaped rail 6 is generated, the roller 15 can be prevented from being derailed inward.

  In addition, as a predetermined position where the restriction plate 23 is attached to the base frame K, the roller 15 is removed from the inside of the greenhouse H by connecting the left and right vertical columns 4 and 4 and the base frame K to each other. On the other hand, since it is not necessary to provide the regulating plate 23 over the entire length in the longitudinal direction of the lower frame 10, the member cost can be reduced.

  Further, the width of the rotation preventing piece 24 formed on the restricting plate 23 is formed to be substantially the same width as the opening width of the fitting groove 14 of the vertical frame 9 and is inserted into and engaged with the fitting groove 14. Even if some external force is applied to the restricting plate 23 to rotate the restricting plate 23, the unintentional rotation of the restricting plate 23 can be prevented by the engagement of the rotation preventing piece 24 and the fitting groove 14. . Further, even when the tightening of the fixing bolt 25 that fixes the restricting plate 23 to the base frame K is loosened, the restricting plate 23 can be similarly prevented from rotating.

  Next, the upper part of the door structure 1 will be described in detail. In addition, since the structure of the door main body M appears left-right symmetrically, it demonstrates by showing one side and abbreviate | omits description about the other suitably.

  Above the house entrance m, a guide rail 7 is laid as shown in FIGS. 2 (a), 2 (b), and 3. FIG. That is, the guide rail 7 is attached between the left and right vertical columns 4 and 4 where the upper edges of the door bodies Ma and Mb are located so that the upper edges of the door bodies Ma and Mb are slidably moved in the left and right directions.

  The guide rail 7 is formed in a U-shaped cross section with a lower opening, and is disposed so as to face the pipe-shaped rail 6 laid under the house entrance m. The guide rail 7 has substantially the same length as the pipe-shaped rail 6 and is attached to the vertical column 4 of the front frame 2 via a rail bracket 60.

  As shown in FIGS. 4, 10, and 11, the rail bracket 60 includes a fixing base frame 61 formed in a substantially trapezoidal cross section and a rail abutment piece 62 that is suspended from the fixing base frame 61. . Specifically, the fixing base frame 61 has a lower leg piece 65 positioned below when the upper and lower base pieces 63 and 64 parallel to each other are set in the left-right direction, and the upper leg piece 66 is perpendicular to the upper and lower bottom pieces 63 and 64. It is gently inclined downward toward the upper bottom piece 63.

  The upper and lower bottom pieces 63 and 64 are provided with U-bolt insertion holes 68 through which the bracket fastening U-bolts 67 are inserted. By forming in this way, the lower base piece 64 is brought into contact with the back surface of the vertical column 4, and the fixing base frame 61 is screwed and fixed from the outside of the greenhouse H by the bracket fastening U bolt 67 and the wing head nut 69.

  The rail contact piece 62 extends the upper bottom piece 63 of the fixing base frame 61 downward and bends the lower end edge inward to form a locking piece 70. That is, the rail contact piece 62 and the lower leg piece 65 form a right angle.

  In the rail bracket 60 formed in this way, a part of the guide rail 7 is fixed in a space formed by the lower leg piece 65 of the fixing base frame 61, the rail contact piece 62, and the back surface of the vertical column 4.

  In addition, the upper edge portion of the upper frame 8 of the door body M is slidably accommodated in the U-shaped interior of the guide rail 7 fixed to the vertical column 4 via the rail bracket 60, and on the upper surface of the upper frame 8. A horizontally rotating upper roller 41 having a diameter D larger than the width w of the upper frame 8 is pivoted, and when the upper frame 8 slides, the upper roller 41 contacts and slides on the inner wall of the guide rail. Thus, the upper edge portion of the upper frame 8 is configured not to contact the inner wall of the guide rail.

  Specifically, as shown in FIGS. 3 and 4, shaft holes (not shown) are formed in the vicinity of both end portions of the upper surface of the upper frame 8, and shaft bolts 42 whose axis is in the vertical direction are formed in the shaft holes. The bolts are inserted so that the heads of the bolts are on the upper side, and are fixed with upper and lower mounting nuts 43 and 44 from above and below. Further, a screwless portion 45 that does not form a male screw is formed on the head side of the shaft bolt 42, and the screwless portion 45 is located above the upper mounting nut 43.

  The upper roller 41 has a circular shape in plan view and is formed in a U-shape with an upper opening in a cross-sectional view, and a shaft insertion hole 46 is formed in the center. Further, the inner diameter of the shaft insertion hole 46 is formed wider than the diameter of the screwless portion 45 on the head side of the shaft bolt 42. Furthermore, since the effective length of the screwless portion 45 is longer than the depth of the shaft insertion hole 46, the upper roller 41 can be horizontally rotated around the shaft bolt 42.

  In this way, the guide rail 7 laid above the house entrance / exit m is formed in a U-shaped cross section with a lower opening, and the upper edge of the upper frame 8 of the door body M is slidably accommodated inside the U-shaped interior. At the same time, a horizontally rotating upper roller 41 having a diameter D larger than the width w of the upper frame 8 is pivoted on the upper surface of the upper frame 8, and when the upper frame 8 slides, the upper roller 41 contacts the inner wall of the guide rail 7. Since the upper edge portion of the upper frame 8 does not come into contact with the inner wall of the guide rail 7 by sliding and rolling, the upper frame 8 is moved to the inner wall of the guide rail 7 when the door body M is opened and closed. Generation of abnormal noise and scratches due to contact with the door body M can be prevented, and the door body M can be smoothly slid left and right.

  Next, the mounting bracket 27 which is the gist of the present invention will be described in detail.

  When laying the pipe-shaped rail 6a below the entrance / exit m of the greenhouse H, as shown in FIGS. 4, 6, and 7, the spacers are attached to the left and right vertical columns 4 and 4 standing on the left and right of the house entrance / exit m. A mounting bracket 27 in which a bracket plate 29 is erected through a base frame 28 is used. Then, the mating pieces 51 and 51 of the mounting ring 50 attached to the pipe-shaped rail 6 are sandwiched and fixed to the upper part of the bracket plate 29. The mating pieces 51, 51 are each provided with an insertion hole (not shown) for the ring mounting bolt 52.

  As shown in FIG. 8A, the spacer mounting base frame 28 of the mounting bracket 27 is formed to have a fixed cross-sectional length, and is used as a tightening bolt 32 as a tightening bolt 32 on both the front and rear walls 30 and 31. Insertion holes 34 for inserting the bolts 32a are formed in two places. Note that the insertion hole 34 is preferably a horizontally long hole in order to facilitate the insertion of the fastening bolt 32 and to absorb an accuracy error of the fastening bolt 32.

  As shown in FIG. 8 (b), if the mounting bracket 27 is a mounting bracket 27a having a plurality of three or more insertion holes 34 in the front and rear walls 30, 31, the insertion position of the fastening U-bolt 32a is provided. Can be adjusted to the left and right positions of the spacer mounting base frame 28 attached to the left and right vertical columns 4 and 4. Further, the insertion hole 34 may be a mounting bracket 27b that is provided at one place on each of the front and rear walls 30, 31 as shown in FIG. In this case, the mounting bracket 27 and the vertical column 4 are connected to a through hole (not shown) provided separately in the vertical column 4 using a single insertion bolt (not shown) instead of the fastening U bolt 32a. ) Is inserted and fixed.

  The bracket plate 29 is formed in a rectangular plate shape by extending the rear wall 31 of the spacer mounting base frame 28 upward. The mounting position of the mounting ring 50 attached to the pipe-shaped rail 6 through the fitting pieces 51, 51 on the upper part of the bracket plate 29 is the upper left and right positions of the bracket plate 29 and the upper left and right positions of the bracket plate 29. The mounting holes 35, the mounting holes 35, and the through holes (not shown) for the ring mounting bolts 52 of the mating pieces 51, 51 are continuously connected to be inserted through the mounting holes 35, 51 and the bracket plate. The mounting ring 50 is fixed to the bracket plate 29 by a ring mounting bolt 52 and a wing head nut 53 for fixing the 29 by integral polymerization.

  As shown in FIG. 9, the mounting bracket 27 has a rectangular plate-like lower part bent forward at a substantially right angle to form a spacer lower piece 36, and the upper central part has the same length as the spacer lower piece 36. The spacer upper piece 37 may be formed by bending forward only. That is, the U-shaped section formed by the spacer upper and lower pieces 36 and 37 and the rear wall 31 of the mounting bracket 27 c corresponds to the spacer mounting base frame 28.

  By forming the mounting bracket 27c in this way, the front end portions of the spacer upper and lower pieces 36 and 37 can be brought into contact with the vertical column 4, and the upper left and right pieces 38 and 38 that are not bent are used as the bracket plate 29. Can do.

It is arranged with a sliding door structure, and the house entrance / exit m can be opened and closed.

  Further, below the house entrance / exit m, the pipe-shaped rail 6 using the mounting bracket 27 which is the gist of the present invention is laid so as to be slightly positioned on the end side of the door main bodies Ma, Mb. That is, the protruding portion 105 is formed by slightly projecting the pipe-shaped rail 6 to the door main bodies Ma and Mb from the vertical column lower ends 4-1 of the vertical columns 4 and 4 erected on the left and right of the house entrance m. Yes. Further, a region without the pipe-shaped rail 6 is a rail-less portion 106.

  Further, a guide locking unit 140 for guiding and clamping a part of the lower edge portion of the door body M from the front and rear is embedded on the ground G side, which is the central part of the wife surface when the door body M is closed. ing.

  A suspension guide rail 110 is laid above the house entrance m. That is, between the left and right vertical columns 4 and 4 where the upper edges of the door bodies Ma and Mb are located, the vertically rotating holding roller 111 is mounted on the upper surface of the door bodies Ma and Mb so as to be slidable vertically. The suspension guide rail 110 is attached so that it may be. The pipe-shaped rail 6 and the suspension guide rail 110 described above will be described in detail later.

  As shown in FIGS. 14 and 15, the lower frame 10 of the door body M is provided with a base frame K having a substantially U-shaped cross section in the lower opening, and the mounting bracket that is the gist of the present invention attached below the base frame K. The pipe-shaped rail 6 using the No. 27 is configured to move while surrounding it.

  Further, holding rollers 111, 111 that are vertically rotatable are pivoted in the vicinity of both ends of the upper surface of the upper side frame 8, and the holding roller 111 rolls against the inner bottom surface of the suspension guide rail 110 that houses the holding roller 111. It is configured to do. That is, the door body M is suspended in a state in which the holding roller 111 is held in the suspension guide rail 110 so as to be slidable to the left and right.

  A door structure 100 that is slidable to the left and right is constituted by the door body M and the peripheral structure thus configured.

  In the following, the specific structure of each part will be described in detail for the lower part of the door structure 100 and then the upper part. In addition, since the structure of the door main body M appears left-right symmetrically, it demonstrates by showing one side and abbreviate | omits description about the other suitably.

  FIG. 15 is a cross-sectional view illustrating a configuration of a portion where the door main body M (the center portion is omitted) is attached to the vertical column 4. The left side of the drawing is the inside of the greenhouse H, and the right side of the drawing is the outside of the greenhouse H.

  As shown in FIG. 12 (a), the pipe-shaped rail 6 has a protruding portion 105 formed on the door main body Ma, Mb side from the vertical column lower end portion 4-1 of the vertical columns 4, 4 erected on the left and right of the house entrance m. Only the door body M is configured to be positioned below the lower frame 10 when the door body M is closed.

  The lower frame 10 constituting the door body M has the same shape as the door body M in the mounting door structure 1 described above, and is different in that the roller 15 is not provided in the base frame K. That is, since the door body M is a suspension door, the lower frame 10 is not in principle in contact with the pipe-like rail 6 partially laid downward, and the base frame K surrounds the pipe-like rail 6. The pipe-shaped rail 6 serves as a guide when the door body M swings back and forth.

  Therefore, if the base frame K surrounds the protruding portion 105, the door main body M is affected by the influence of the outside wind even if the lower frame 10 is located at the railless portion 106 when the door main body M is closed. Can be prevented from shaking into the greenhouse H.

  Further, as shown in FIG. 16, the guide locking unit 140 includes a rectangular plate-shaped guide plate 141 whose both ends in the longitudinal direction are curved outward and an anchor 143 for fixing the guide plate 141 to the ground G.
