Description

  The present invention relates to a sheet shutter, and more specifically, it is possible to increase the sealing degree between a sheet and a frame constituting the sheet shutter, and to prevent dust and the like from entering the room through a gap between the sheet and the frame. It relates to the sheet shutter.

  Conventionally, in a factory, a warehouse, etc., in order to prevent invasion of dust, insects, and the like from the outside, a sheet shutter is attached to the doorway. And by closing the doorway with this sheet shutter, it is possible to prevent dust, insects and the like from entering the factory and warehouse.

  Here, a conventional sheet shutter will be described. FIG. 8 is a diagram for explaining a conventional sheet shutter 31. In FIG. 8, the conventional sheet shutter 31 is an upper frame attached to an entrance of a warehouse, a factory, or the like. 33 and the left and right side frames 34 constitute a gate-type frame 32, and a sheet 35 is suspended in a space surrounded by the frame 32 so as to be freely wound and unwound.

  That is, a rotary shaft (not shown) is rotatably mounted in the upper frame 33, and a motor, which is a driving means for rotating the rotary shaft, is connected to the rotary shaft.

  One end of a belt 36 as a traction member is fixed to the rotating shaft, and the other end of the belt 36 is fixed at an arbitrary position in the upper frame 33.

  Further, a suspension shaft is provided in the upper frame 33, and a seat 35 is suspended from the suspension shaft. The seat 35 can close a space surrounded by the frame 32. , And is supported by the belt 36. That is, the other end of the belt 36 is fixed in the upper frame 33 while the front and back of the seat 35 are bridged from the lower part.

  In such a configuration, when the motor is driven to rotate the rotating shaft, the belt 36 is wound around the rotating shaft, and the seat 35 supported by the belt 36 rises, while the motor When the rotating shaft is rotated in the opposite direction to the above, the belt 36 wound around the rotating shaft is unwound, whereby the sheet 35 supported by the belt 36 is unwound. It is possible to descend.

  By the way, in the conventional sheet shutter configured as described above, the sheet 35 is spaced apart in the vertical direction and the core material in the left-right width direction in order to counter the strong wind. Was built in.

  This core material will be described. FIG. 9 is a view showing a part of a longitudinal side surface structure of the sheet 35, in which 38 is a core material. That is, in the conventional sheet shutter 31, the elongated bag-shaped core material accommodating portion 37 that is hollow toward the width direction of the sheet 35 is provided inside the sheet 35 at a certain interval in the vertical direction of the sheet. The core material 38 having a length substantially equal to the width of the sheet 35 is accommodated in the core material accommodating portion 37.

  As a result, even when a strong wind blows on the sheet, the sheet is prevented from shaking or dripping.

  Here, FIG. 10 is a diagram showing a transverse plane of the conventional sheet shutter 31. In general, in the sheet shutter, both end portions in the left and right width directions of the sheet 35 are located in the side frame 34. The part located in the side frame 34 is in contact with the inner wall of the side frame 34 along the vertical direction of the surface facing the indoor side of a factory, warehouse, etc. Intrusion into the room from between the left and right end portions 35 and the side frame 34 is prevented.

  However, in the conventional sheet shutter, the core material accommodating portion is formed in the sheet for facing when the strong wind blows, and the core material is accommodated in the core material accommodating portion. As shown in the figure, the portion containing the core member 38 is swollen toward both the front and back surfaces than the other portions. For this reason, the surface or the back surface of the portion located in the side frame 34 The entire region along the vertical direction could not be brought into contact with the inner wall of the side frame 34.

  Therefore, with the conventional sheet shutter, it is difficult to ensure the degree of sealing between the side frame and the seat without any allowance, which may cause dust, insects, etc. to enter the room. It was high.

  Accordingly, the present invention provides a sheet shutter that can effectively prevent dust, insects, and the like from entering the interior by increasing the degree of sealing between the sheet and the side frame in a sheet shutter using a sheet having a core material. The challenge is to do.

  An embodiment of the sheet shutter according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a part of the sheet shutter according to the present embodiment. In the figure, 1 is the sheet shutter according to the present embodiment.

  The sheet shutter 1 of this embodiment has an upper frame. That is, in FIG. 1, 3 is an upper frame, and in this embodiment, the left and right side frames 4 in the shape of a substantially grooved steel are formed on the lower side in the vicinity of both ends of the upper frame 3 in a substantially vertical direction. The upper frame 3 and the left and right side frames 4 are connected to each other so as to form a gate-type frame 2, and the frame 2 is attached to an entrance / exit of a factory, a warehouse, or the like.

  In addition, a suspension shaft 14 is provided in the frame 2 in the width direction, and the seat 5 is suspended through the suspension shaft 14 so as to close a space surrounded by the frame 2. The seat 5 is raised or lowered to open and close the entrances and exits of factories and warehouses.

  Here, a mechanism for raising or lowering the seat 5 will be described with reference to FIGS. 3 to 5. FIG. 3 is a view showing a structure in the upper frame 3, and FIGS. It is a figure for demonstrating the mechanism to raise or lower 5.

  A rotating shaft 6 is rotatably disposed in the upper frame 3 in the left-right direction. The rotating shaft 6 is connected to a rotating shaft of a motor 7 as a driving means. Thus, the rotation shaft 6 can be rotated by driving the motor 7.

  Next, one end of a belt 8 as a traction member is fixed to the rotary shaft 6 via a pulley 15, and the other end of the belt 8 spans the front and back of the seat 5 from below. The belt 8 is fixed at an arbitrary position in the upper frame 3 so that the belt 8 can be raised while supporting the seat 5.

  That is, in FIG. 4, when the rotating shaft 6 is rotated in the direction of the arrow by the motor 7, the belt 8 having one end fixed to the rotating shaft 6 is wound around the rotating shaft 6 and the lower end portion thereof rises. . Then, as the belt 8 is raised, the sheet 5 supported by the belt 8 is wound up, and thus the sheet 5 can be raised. FIG. 5 shows a state in which the seat 5 is raised.

  Then, when the rotary shaft 6 is rotated in the opposite direction with the seat 5 fully raised, the belt 8 wound around the rotary shaft 6 is unwound, thereby lowering the seat 5. It becomes possible. FIG. 4 shows a state in which the sheet 5 is lowered. Accordingly, the seat shutter 1 of the present embodiment can open and close the entrances and exits of factories, warehouses, etc. by raising or lowering the seat 5 by driving the motor 7 as in the conventional seat shutter.

  Next, in the sheet shutter 1 of the present embodiment, the sheet 5 is provided with a core material in the left-right direction with an interval in the vertical direction, and even when a strong wind is blown by the core material, the sheet 5 is provided. Is able to compete sufficiently.

  In the sheet shutter 1 of the present embodiment, the core material is provided only on one surface of the sheet 5.

  This core material will be described. FIG. 6A is a diagram showing a longitudinal side surface structure in the vicinity of the core material portion in the sheet 5, and in the sheet shutter 1 of the present embodiment, the surface on one side of the sheet 5 Specifically, a bag-shaped core material accommodating portion 9 facing the width direction on the right and left sides is connected to the outer surface of the factory, warehouse, etc. in the seat 5 with an interval in the vertical direction. A core material 10 of a round pipe is accommodated in the core material accommodating portion 9 over the entire region in the left and right width directions.

  Therefore, as is clear from FIG. 6, in the sheet shutter 1 of the present embodiment, the surface opposite to the surface provided with the core material 10 can be flattened over the entire surface. Unlike the conventional sheet shutter, where both the front and back surfaces of the housing location are swollen, the flat surface of the seat 5 and the side frame 4 can be brought into close contact with each other, and the degree of sealing in the building can be increased. It is.

  FIG. 6B shows a longitudinal side surface of the lower end portion of the sheet 5, and in the lower end portion of the sheet 5 in this embodiment, the vicinity of the lower end portion is folded back to the side where the core material accommodating portion 9 is connected. A core material accommodating portion 9 is formed, and the core material 10 is accommodated in the core material accommodating portion 9.

  In FIG. 6B, 16 is a fin. That is, in this embodiment, a flexible rubber fin 16 is connected to the lower end portion of the sheet 5 over the entire width direction of the sheet 5, and the sheet 5 is lowered to prepare for the lower end of the sheet 5. When the core material 10 reaches the vicinity of the floor surface, the fins 16 come into contact with the floor surface to completely seal the sheet 5 and the floor surface.

  Next, FIG. 2 is a diagram showing a transverse plane near one side of the side frame 4, FIG. 7 is a diagram showing a cross-sectional structure taken along the line AA in FIG. It is a sealing member for increasing the degree of adhesion with the sheet 5.

  That is, the degree of adhesion between the flat surface of the sheet 5 and the side frame 4 can be obtained only by flattening the surface opposite to the surface provided with the core material 10 on one surface of the sheet 5. Since it is difficult to further increase, in the seat shutter 1 of the present embodiment, in the side frame 4, a seal member 11 is provided across the entire vertical direction at a location facing the flat surface of the seat 5. The seat 5 comes into contact with the seal member 11, thereby increasing the degree of adhesion between the seat 5 and the inner wall of the side frame 4.

  Next, in the figure, 12 is a fin provided on the side frame 4. That is, the sheet shutter 1 of the present embodiment includes the fins 12 that are in contact with the sheet 5 in the vertical direction of the sheet 5 on the outer side (the other side frame side) of the seal member 11.

  Therefore, the presence of the fins 12 makes it possible to completely seal the interior of a building or the like with respect to the outside of the seat 5 as shown in FIG.

  Therefore, in the seat shutter 1 of the present embodiment, the close contact between the side frame 4 and the sheet 5 can be increased due to the presence of the seal member 11 and, for some reason, dust, insects and the like are caught between the side frame 4 and the sheet 5. Even if an object tries to enter the inside of the building, the presence of the fins 12 can prevent the intrusion.

  In addition, as shown in FIG. 7, when the seat 5 is lowered by the fins 16 connected to the lower end of the seat 5, the fins 16 can completely seal the seat and the floor surface. Is possible.

  In this embodiment, the sealing member 11 is made of hollow rubber, and the fins 12 are also made of flexible and deformable rubber.

  In the present embodiment, a mounting bracket 1201 is attached between the inner wall of the side frame 4 and the seal member 11, and the fin 12 can be brought into contact with the mounting bracket 1201 and the fin 12 can contact the seat 5. Connected by arrangement.

  Next, in FIG. 7, 13 is a partition plate. That is, in this embodiment, in the side frame 4, the lower portion of the inner wall facing the seal member 11 is tapered in the side frame 4 toward the seal member 11 toward the lower side. The protruding partition plate 13 protrudes. The presence of the partition plate 13 makes it possible to effectively prevent the lower end portion of the sheet 5 from shaking greatly even when strong wind or the like is blown onto the sheet 5.

  Next, the operation of the thus configured sheet shutter 1 of the present embodiment will be described. In the sheet shutter 1 of the present embodiment, the core material accommodating portion is provided on the outer surface of the sheet 5 such as a factory or a warehouse. 9 is provided with a core material 10, and the surface on the inner side of the building in the seat 5 is flattened over the entire surface, so that the seat 5 and the side frame 4 can be brought into close contact with each other. It is possible to increase the degree of sealing.

  At that time, in the seat shutter 1 of the present embodiment, the seal member 11 is provided in the side frame 4 at a location facing the flat surface of the seat 5 over the entire vertical direction. The degree of close contact with the inner wall of the frame 4 can be further increased. Further, since the fins 12 that come into contact with the seat 5 are provided outside the side frame 4, the side frame 4 and the seat 5 for some reason. Even if dust, insects, etc. try to enter the inside of the building from between them, the presence of the fins 12 can prevent the entry.

  Furthermore, in the side frame 4, the lower portion of the inner wall on the side facing the seal member 11 is provided with a partition plate 13 projecting into the side frame 4 in a tapered shape as it goes downward. Even when strong wind or the like is blown onto the sheet 5, it is possible to effectively prevent the lower end portion of the sheet 5 from shaking greatly, and to maintain the close contact between the inner wall of the side frame 4 and the sheet 5.

  Also, fins 16 are provided at the lower end of the sheet 5, and when the core member 10 is brought near the floor surface by lowering the sheet 5 and provided at the lower end of the sheet 5, the fins 16 abut against the floor surface, 5 and the floor surface can be completely sealed, so that the sheet and the floor surface can be sealed at the lower end portion of the sheet, and buildings such as dust and insects are formed between the sheet 5 and the floor surface. It is also possible to prevent intrusion into the inside.

  Thus, in the sheet shutter 1 of the present embodiment, it is possible to increase the degree of adhesion between both end portions of the sheet and the inner wall of the side frame, and it is also possible to increase the degree of adhesion between the sheet and the floor surface. For this reason, it is possible to increase the sealing degree in the building and effectively prevent dust, insects and the like from entering the room.

  In the sheet shutter 1 of the present invention, a surface different from the surface provided with the core material in the sheet 5 is flattened over the entire surface, and a rubber seal member is provided on the inner wall of the side frame that contacts the flattened surface. As long as it is provided, the partition plate is not necessarily required.

  In the seat shutter of the present invention, the sealing degree between the sheet and the side frame can be increased without being affected by the core material, and therefore, the sheet shutter can be applied to all sheet shutters including the core material.
