When the rotary protrusion 65 comes into contact with the brake part 55, if the rotary protrusion 65 is configured so as to be hooked with the brake part 55, even when an external force which causes the rotary protrusion 65 to ride over the brake part 55 acts on, the rotary protrusion 65 is not disconnected from the brake part 55 easily, and the panel 2 is not disconnected from the support shaft 51 easily.SELECTED DRAWING: Figure 9

Description

  The present invention relates to a gate for opening and closing a doorway in a temporary soundproof panel provided at a construction work site or a dismantling work site, and more particularly to a hinge structure for connecting door bodies of the gate doors so as to be foldable.

  Generally, at a construction work site or a demolition work site, the surroundings of a building are covered with a temporary enclosure to suppress scattering of dust and the like due to construction, and leakage of construction noise to the outside. In such a temporary enclosure, large vehicles often pass through entrances and exits for construction vehicles, so in general the opening width is wide. A sliding door type configuration in which the doorway is opened and closed by moving toward the side end is often used, and among them, a configuration in which a large number of panels are connected so as to be foldable via hinge members is often used.

  In the gate door, when the connected panels are folded, in a plan view, the places where the door bodies are folded in a mountain fold shape and the places where the door folds are folded in a fold shape are alternately arranged. The gate can be folded smoothly.

  Various forms have been proposed as the form of the hinge member.For example, in Patent Document 1, a plurality of panels are foldably connected via a joint member as a hinge member to constitute a panel unit. A pair of support shafts are formed on each joint member, and an intermediate cylindrical support shaft having a vertical notch groove is rotatable on each support shaft of at least one of the first and second joint members. A folding door is disclosed in which a panel vertical hook is engaged with an outer periphery of the intermediate cylindrical spindle.

Japanese Patent Application Laid-Open No. 07-180449

  By the way, in the folding door of patent document 1, it is possible to adjust the folding angle range of the connected panel unit by the notch width etc. of the vertical notch groove of an intermediate | middle cylindrical spindle, Specifically, it is connected. The formed panels are connected so as to be movable in a range from a state where they are arranged in a straight line with a joint member interposed therebetween. However, in a state where the panels are arranged in a straight line to close the doorway, when the strong wind is received from the front or back of the panel, the folding member is reversely folded in the direction opposite to the normal folding direction of the panel units. In some cases, a part of the joint member may be damaged, or the intermediate cylindrical support shaft may come off from the support shaft of the joint member, and the connection between the panel units may be disconnected.

  The present invention provides a hinge structure in which, when the panels are foldably connected to each other, even if acting in the reverse folding direction, the panels are unlikely to be reversely folded and the panels are not easily disconnected. .

In order to achieve the above object, the present invention is configured as follows.
That is, the hinge structure according to the present invention is

A hinge structure in which the panels are foldably connected to each other, and when the panel is rotated, a support shaft that serves as a rotation shaft, and a groove portion that is provided on one side surface of the vertical frame of the panel and into which the support shaft is inserted. The groove portion includes a rotating convex portion that protrudes toward the inserted support shaft, and the outer peripheral surface of the support shaft includes a braking portion that brakes the rotation of the rotating convex portion, The rotating convex portion is configured to be hooked on the braking portion when the rotating convex portion abuts on the braking portion.

  In the hinge structure according to the present invention, the braking portion includes a concave portion that is recessed inward, and when the rotating convex portion comes into contact with the braking portion, a part of the rotating convex portion is in the concave portion. You may be comprised so that it may be located in.

  According to the present invention, when the rotating convex portion rotates and contacts the braking portion, the rotating convex portion is configured to be hooked on the braking portion. Further, even if an external force is applied in the same direction as the rotation direction, the rotation convex portion is caught by the braking portion and does not easily come off, so that a problem that the panel is detached from the support shaft is less likely to occur.

  In the present invention, a concave portion that is recessed toward the inside of the braking portion is provided, and when the rotating convex portion comes into contact with the braking portion, a part of the rotating convex portion is positioned in the concave portion. If it comprises, since a rotation convex part becomes still more difficult to remove | deviate from a brake part, the said malfunction becomes difficult to occur and it is preferable.

  Next, the best mode for carrying out the present invention will be specifically described with reference to the drawings.

  FIG. 1 is a front view showing an embodiment of a gate using a hinge structure according to the present invention. The gate G is a pair of gate pillars 1 erected at a predetermined interval, a beam 11 attached between the gate pillars 1, and suspended from the beam 11 so as to be movable in the longitudinal direction of the beam 11. A lowered vertical beam 12 and a panel 2 attached to the vertical beam 12 are provided. Thereby, the panel 2 can be moved along the length direction of the beam 11 by the vertical rail 12.

  2 is a front view of the panel of FIG. 1, FIG. 3 is an enlarged view of the main part of the AA cross section of FIG. 2, and FIG. 4 is an enlarged view of the main part of the BB cross section of FIG. In the present embodiment, the panel 2 has a panel body 22 attached to the inside of a rectangular frame 21. That is, the frame 21 is arranged along the outer peripheral edge of the panel body 22 to form the panel 2.

  In this embodiment, the frame body 21 is formed in a rectangular shape by a pair of left and right vertical frames 23 and a pair of upper and lower horizontal frames 24, and is continuous with the inner wall portion of the frame body 21 along its longitudinal direction. Insertion grooves 25 and 26 are provided. That is, as shown in FIGS. 3 and 4, an insertion groove 25 and an insertion groove 26 are provided in the inner walls of the vertical frame 23 and the horizontal frame 24, and the panel body 22 is provided in the insertion groove 25 and the insertion groove 26. As a result, the panel body 22 is fixed by the frame body 21.

  In this embodiment, the panel main body 22 is a form in which a metal plate is attached to both surfaces of a synthetic resin sheet-like core material, and the metal plate, the core material, and the metal plate are laminated in this order, and is lightweight and has sound insulation performance. It is excellent in that it is preferable. The thickness of the core material is preferably 1 to 10 mm, more preferably 1 to 3 mm in consideration of moldability, strength, handleability, and the like. In addition, the thickness of the metal plate is preferably 0.05 to 1 mm in consideration of weight, workability, handling, and the like.

  The panel main body 22 is not limited to this form, and may be formed only from a plate material made of synthetic resin, or may be only a metal plate. In short, dust generated in the site is scattered outside the site. It is preferable that it is difficult to cause the generated noise to leak to the site side.

  In this embodiment, the panel 2 is provided with the frame body 21. However, the panel 2 may not include the frame body 21 as long as the panel 2 can be pivotably connected via the hinge structure 3. That is, if it is a form provided with at least the vertical frame 23, it becomes easy to configure the hinge structure 3 using the vertical frame 23, which is preferable.

  5 and 6 are explanatory views showing the movable state of the gate G in FIG. The vertical frames 23 of the panel 2 are connected via a hinge structure 3 and a connecting member 4. As shown in FIG. 5, the panels 2 are movable between a state where the panels 2 are expanded with the hinge structure 3 and the connecting member 4 as axes, and a state where the panels 2 are folded as shown in FIG. It has been. In addition, the hinge structure 3 and the connection member 4 may use the thing of the same form, and the form according to folding directions, such as interference of the panels 2 when it folds in consideration of the designability from the site outer side, etc. In short, it is only necessary that the connected panels 2 be smoothly folded or expanded.

  As shown in FIG. 3, the hinge structure 3 is continuously formed in the longitudinal direction on one side surface of a support shaft 51 that serves as a rotation axis of the panel 2 and the vertical frame 23 of the panel 2 when the panel 2 is rotated. And a groove 61 into which the support shaft 51 is inserted.

  The hinge structure 3 includes two support shafts 51 corresponding to the two panels 2 to be connected, and the support shafts 51 are connected to each other via an intermediate member 52. The support shaft 51 is formed continuously along the vertical direction, and its outer peripheral portion is formed in a cylindrical shape. In this embodiment, a part of the cylindrical shape is a substantially C-shape that is continuously cut out in the vertical direction, but it may be simply formed in a cylindrical shape or a solid columnar shape. Good.

  The groove part 61 is provided with the opening part 62 opened toward a side. The two support shafts 51 are connected to each other by an intermediate member 52 that passes through the opening 62 from the support shaft 51 inserted into the groove portion 61. Accordingly, the panel 2 can be rotated about the support shaft 51 disposed in the groove 61 in a state where the intermediate member 52 has passed through the opening 62.

  Next, the relationship between the groove 6 and the support shaft 51 will be described in more detail with reference to FIGS. The groove portion 61 includes rotating convex portions 64 and 65 protruding from the inner wall portion 63 toward the outer peripheral surface 53 of the support shaft 51. The rotating convex portions 64 and 65 are arranged to face each other with the support shaft 51 therebetween, and the protruding end portions of the rotating convex portion 64 and the rotating convex portion 65 are the outer peripheral surfaces 53 of the support shaft 51. It is configured to be rotatable along the outer peripheral surface 53 in a state where it is in contact with or close to the outer peripheral surface 53.

  Further, the outer peripheral surface 53 includes braking portions 54 and 55 that protrude toward the inner wall portion 63 of the groove portion 61. Accordingly, when the panel 2 is rotated in the X direction in FIG. 7, as shown in FIG. 8, the rotation convex portion 64 is rotated along the outer peripheral surface 53 and is brought into contact with the braking portion 54, so It is possible to rotate until the state is folded. Further, when the panel 2 is rotated in the Y direction in FIG. 7, the rotation convex portion 65 is rotated along the outer peripheral surface 53 until it is brought into contact with the braking portion 55 as shown in FIG. 9. be able to. Note that the rotation range of the panel 2 can be adjusted by the positions of the braking portions 54 and 55.

  In FIG. 9, as described above, since the rotation convex portion 65 is in contact with the braking portion 55, it does not rotate any more in the Y direction. However, when an external force is applied that causes the connected panel 2 to be folded backward beyond the original rotation range, for example, a strong wind hits the panel 2 from the S direction from the lower side to the upper side in FIG. There is a risk that the groove portion 61 may come off the support shaft 51 over the braking portion 55.

  FIG. 10 is an enlarged view of the vicinity of the contact portion when the rotating convex portion 65 is rotated and contacted with the braking portion 55 in FIG. 9. The rotating convex portion 65 is configured to be hooked on the braking portion 55 when being brought into contact with the braking portion 55. As a result, the turning convex portion 65 is not easily detached from the braking portion 55, and it is possible to suppress a problem that the turning portion 6 is easily detached from the support shaft 51.

  As shown in FIG. 10, a concave portion 56 is formed on one side surface of the braking portion 55, and at least a part of the rotational convex portion 65 is formed in the concave portion 56. What is comprised so that it may be arrange | positioned to can be mentioned. The concave portion 56 may be formed by relatively projecting from the projecting distal end side of the braking portion 55 toward the rotating convex portion 65, thereby forming the concave portion 56 on the proximal end side of the braking portion 55. The base end side may be recessed inward to form the recess 56. By forming the concave portion 56 as described above, it is difficult for the rotating convex portion 65 located in the concave portion 56 to easily get over the protruding front end side of the braking portion 55. Does not easily disengage from the braking portion 55, and the inconvenience that the rotating portion 6 easily disengages from the support shaft 51 can be suppressed. It is more preferable that the rotating convex portion 65 located in the concave portion 56 includes a portion that is in contact with the braking portion 55 because it is more difficult to come off the braking portion 55.

  The panels connected by the hinge structure according to the present invention are not easily folded backward even if an external force is applied in the reverse folding direction, and the panel is difficult to be detached from the support shaft. Can be suitably used.
