Description

  The present invention relates to a gap sealing magnet sheet set and a sheet used for sealing a door gap in a factory where a clean room is required such as a food factory or a pharmaceutical factory.

  In food factories and pharmaceutical factories, a clean room is required to prevent the entry of foreign substances such as insects from the outside. On the other hand, there are gaps for opening and closing between people and articles entering and leaving the factory, and openings such as emergency exits, windows, and inspection openings and the doors that close the openings. Therefore, it is necessary to seal this gap.

  As a conventional technique, for example, a magnet is fitted on the floor surface immediately below the lower surface of the revolving door in the closed position so that the door surface is substantially full and no irregularities are formed on the floor surface, and a magnetic fluid is enclosed therein. There is a rotating door seal structure in which a magnetic seal member, in which a bottom portion of the container is made of an elastic material and a rigid material is disposed on both sides of the container, is attached to the lower surface of the door (Patent Document) 1).

  Alternatively, the door gap may be sealed by caulking or the like.

Special H7-018303

  However, it is expensive to fit a magnet into the floor on the lower surface of the door. In particular, it is difficult to process later.

  On the other hand, it is easy to seal the gap of the door with caulking or the like, but in this case, the door cannot be opened. Therefore, this means is not suitable for an opening such as an emergency exit that needs to be quickly opened and closed in an emergency.

  Therefore, there is a need for a sealing means that can be easily attached and, if necessary, can easily open and close a door such as a door and can be easily re-sealed.

<< Embodiment 1 >>
<Embodiment 1: Overview>

  The magnet sheet set of the present embodiment has a function of sealing a gap formed between the door and the door frame by the door side sheet and the door frame side sheet, and the first magnetic attachment surface of the door side sheet and the door frame It is characterized in that a gap is sealed by magnetically adhering to the second magnetized surface of the side sheet and that a groove is provided in the first magnetized surface.

In the present specification, the “door” is not limited to a door, but includes an openable / closable door provided at a window, an inspection port, or the like.
<Embodiment 1: Configuration>

  FIG. 1 is a conceptual diagram illustrating an example of a magnet sheet set according to the present embodiment. (A) is a plan view, (b) is a bottom view, and (c) is a cross-sectional view.

  As shown in this figure, the magnet sheet set of the present embodiment is composed of a “door side sheet” (0101) and a “door frame side sheet” (0102).

  A door side sheet | seat is a sheet-like member which should be affixed and used for the door side.

  A door frame side sheet | seat is a sheet-like member which should be affixed and used for the door frame side.

The magnet sheet set of the present embodiment has a function of sealing a gap when the first magnetized surface (0104) of the door side sheet and the second magnetized surface (0107) of the door frame side sheet are magnetically adhered. Have.
<Door side sheet>

The door side sheet | seat of the magnet sheet set of this embodiment has a 1st sticking surface, a 1st magnetic attachment surface, and a groove | channel.
<First surface>

  The “first pasting surface” (0103) is a surface to be disposed on the door surface side of the door-side sheet. It has a function of fixing the door side sheet itself along the outer edge of the door surface.

  The “outer edge of the door surface” is a portion close to the periphery of the door surface.

The fixing means is not particularly limited, but if an adhesive tape is used, it can be easily fixed along the outer edge of the door surface by sticking.
<First magnetized surface>

  The “first magnetic attachment surface” (0104) has a function for magnetically adhering to a door frame side sheet to be described later. It comes out in a bowl shape from the outer edge of the door surface and is in close contact with the second magnetized surface of the door frame side sheet. The first magnetized surface may be a magnet, or when the second magnetized surface is a magnet, it may be a magnetic metal that can be in close contact with the magnet by magnetic force.

  In order to prevent dust from being generated due to contact between the magnetized surfaces, it is preferable to coat a rubber magnet in which a magnetic material is kneaded with rubber or a surface of the magnet or magnetic metal with a synthetic resin. In particular, when a rubber magnet is used, sealing can be reliably performed because it follows the distortion and distortion of the door.

  FIG. 2 is a conceptual diagram showing an example of the usage state of the magnet sheet set of the present embodiment. (A) is a door in a closed state, (b) is an AA partial cross-sectional enlarged view of this door, (c) is a door in an open state, (d) is an enlarged partial cross-sectional view of this door along BB. Represents. Further, (e) is a partially enlarged view enlarging a circle portion indicated by a dotted line in order to show the corner of the door of (a), and the door frame and the door are indicated by a dotted line. This figure shows a door (0201), a door frame (0202), a door side sheet (0203), and a door frame side sheet (0204). In addition, the door side sheet | seat and the door frame side sheet | seat are abbreviate | omitted in (a) and (c).

“Exiting from the outer edge of the door surface in a bowl shape” means that the door frame protrudes from the outer periphery of the door surface to the door frame side, as shown in FIG. It means that at least a part of the surface covers a part of the door frame. As a result, the first magnetized surface can be in close contact with the second magnetized surface of the door frame side sheet.
(Four corners processing)

Further, as for the processing of the four corner portions of the door, for example, as shown in (e) in this figure, the end of the strip-shaped door-side sheet is cut obliquely and combined so that no gap is generated. . As will be described later, since the groove is provided on the first magnetized surface of the door-side sheet, it is flexibly bent in the short direction perpendicular to the longitudinal direction rather than in the longitudinal direction. Therefore, when the door and the door frame are not on the same plane and there is a step, if the longitudinal direction hits the step part, there is a possibility that a gap will form in this part. It is preferable to cut and combine. Further, when a gap is generated in the combined portion, the gap can be eliminated by filling this portion with caulking.
<Groove>

  Refer to FIG. 1 again.

  A “groove” (0105) is provided on the first magnetically attached surface. The groove can also be provided by forming a part of the magnet sheet thin. Alternatively, as shown in this figure, a magnet formed in a strip shape can be provided by fixing a magnet on a base sheet with a certain gap.

  In addition, the sheet | seat used as a foundation is not a structure essential to the magnet sheet set of this embodiment. Also, the material is not particularly limited as long as it is a sheet-like member such as synthetic resin, paper, cloth, and rubber. However, since the base sheet is a portion that is exposed on the surface, it is preferably a durable material. For example, “ICCSSO” of Sigma Paper Industry Co., Ltd. can be used.

  This groove has a function of allowing the first magnetic adhesion surface to be bent along the outer edge of the door.

FIG. 3 is a partial cross-sectional view showing another example of the usage state of the magnet sheet set of the present embodiment. This figure shows a door (0301), a door frame (0302), a door side sheet (0303), and a door frame side sheet (0304). Compared to (a) in this figure, in (b), the door and the door frame are not on the same plane, and a step is generated. Even in such a case, the magnetic sheet set of the present embodiment has a groove (0305), so that the first magnetic attachment surface can be easily bent along the outer edge of the door, and the gap is sealed. Can do. As a result, the magnet sheet set of this embodiment can be used for various doors.
(Number of grooves)

The number of grooves is not particularly limited as long as it is one or more. For example, there are two such as (a) and (b) in this figure. If there are two or more grooves, and the gap is small, as shown in (c) of this figure, if the part of the door side sheet is cut off at the groove part, the width of the magnet sheet set can be narrowed. Is good. Alternatively, the number of grooves may be three or more.
(Width of groove)

Further, the width of the groove is not particularly limited. If the width of the groove is too narrow, it cannot be bent freely, such as the thickness of the magnet part colliding. When a part of the two magnetized surfaces comes into contact, the area to be magnetized decreases, which may reduce the sealing effect. For example, the width of the groove may be about 1 mm to 3 mm.
(Distance between grooves)

  The distance between the grooves is not particularly limited. The interval between the grooves is the length of the portion indicated by the double-headed arrow in FIG. 1B, and includes the length of the groove and the end of the door side sheet. If the gap between the grooves is too wide, it becomes difficult to cope with the step, but if it is too narrow, the area to be magnetized decreases and the sealing effect may be reduced. For example, the thickness may be about 5 mm to 10 mm.

  3A and 3B are examples in which the number of grooves is two, the width of the grooves is about 2 mm, and the distance between the grooves is about 10 mm. Similarly, (d) is an example in which the number of grooves is three, the width of the grooves is about 2 mm, and the distance between the grooves is about 5 mm.

  When the number of grooves is increased as shown in (d), fine adjustment can be made even when the door-side sheet of the magnet sheet set is cut off at the groove portion. Moreover, since there are many bendable parts, it can respond to fine steps. Furthermore, if the constituent material of the magnetized surface is a followable material such as a rubber magnet as described above, for example, there is a difference in the height between the upper and lower portions of the door and the gap between the door and the frame, It can be used for doors with distortion and distortion, increasing versatility.

On the other hand, as shown in (a) and (b), a case where the gap between the grooves is relatively wide is suitable when the gap between the doors is relatively wide.
<Door frame side sheet>

  Refer to FIG. 1 again.

The door frame side sheet of the magnet sheet set of the present embodiment has a second sticking surface and a second magnetized surface.
<Second surface>

  The “second sticking surface” (0106) is a surface to be disposed on the door frame surface side of the door frame side sheet. It has a function of fixing the door frame side sheet itself along the door side edge of the door frame surface.

  The “door side edge of the door frame surface” is a portion near the door side of the door frame surface, that is, the inner peripheral edge.

The fixing means is not particularly limited, but if an adhesive tape is used, it can be easily fixed along the outer frame of the door surface by sticking.
<Second magnetized surface>

  The “second magnetized surface” (0107) has a function for magnetically adhering to the door-side sheet described above. The second magnetized surface may be a magnet, or when the first magnetized surface is a magnet, it may be a magnetic metal that can be in close contact with this magnet by magnetic force.

  In order to prevent dust from being generated due to contact between the magnetized surfaces, it is preferable to coat a rubber magnet in which a magnetic material is kneaded with rubber or a surface of the magnet or magnetic metal with a synthetic resin. In particular, when a rubber magnet is used, sealing can be reliably performed because it follows the distortion and distortion of the door.

Refer to FIG. 2 again. In the magnet sheet set of this embodiment, since the sealing is performed by magnetic force adhesion, the door can be opened easily. Also, when sealing again after the door is opened, the first magnetic adhesion surface and the second magnetic adhesion surface may be overlapped again and brought into magnetic contact, and re-sealing is easy.
<Embodiment 1: Effect>

The magnet sheet set of this embodiment can be easily attached to the door, and when necessary, the door can be easily opened and closed and re-sealing can be easily performed.

<Door frame side sheet>

The door frame side sheet has a fourth sticking surface, a fourth magnetic adhesion surface, and a groove. The fourth sticking surface has the same configuration as the first sticking surface, the first magnetizing surface, and the groove described in the first embodiment with respect to the fourth magnetizing surface and the groove.
<Embodiment 2: Effect>

The magnet sheet set of this embodiment can be easily attached to the door, and when necessary, the door can be easily opened and closed and re-sealing can be easily performed.
