Japanese Patent Laid-Open No. 02-269286

  However, in the soundproof and airtight automatic door described in Patent Document 1, the rail member needs to be bent, and there is a problem that the manufacturing cost increases. In addition, in the soundproof and airtight automatic door described in Patent Document 1, since the airtightness depends on the position adjustment between the rail and the door when the soundproof and airtight door is installed, the adjustment tends to be difficult and the cost tends to increase. is there.

  An object of the present invention is to provide an airtight door capable of realizing low cost while maintaining high airtightness with a single drive source.

(1)
An airtight door according to the present invention includes a door body that slides open and close with respect to a doorway, a partial panel that is provided so as to protrude from one side of the door body and that is attached to a peripheral edge of the doorway. And an extruding mechanism for projecting and moving the partial panel from the door body toward the door in a closed position where the door is closed.

  In the hermetic door according to the present invention, the partial panel on which the sealing material is mounted is projected and moved toward the door by the push-out mechanism, and is in close contact with the periphery of the door.

  In this case, the airtightness can be easily improved by replacing the conventional door with the airtight door according to the present invention. That is, there is no need to bend the rail member in order to move the door body toward the doorway side while sliding and opening the door body, and a standard rail member and a hardware member such as a hanger can be used. As a result, since it is not influenced by the position adjustment between the rail member and the doorway at the time of installation, low cost can be realized while maintaining high airtightness with a single drive source.

(2)
The extrusion mechanism may include one or more link mechanisms.

  In this case, since the extrusion mechanism includes one or a plurality of link mechanisms, the partial panel can be smoothly projected and moved from the door body. Moreover, since a fixed moving distance can be ensured by the link mechanism, the doorway can be reliably sealed.

(3)
The push-out mechanism includes an elastic member that urges the part panel that has been protruded and moved to be housed in the door body.

  In this case, the partial panel is accommodated in the door body by the elastic member included in the pushing mechanism. As a result, an electric drive source for housing the partial panel in the door is not necessary, and energy saving and cost saving can be realized.

(4)
The link mechanism may include one or more links.

  In this case, since the link mechanism includes one or a plurality of links, it is possible to reliably hold the door body and the partial panel and ensure a certain moving distance.

(5)
The links may be individually connected to the elastic member.

  In this case, each link can be rotated by one or a plurality of elastic members, and as a result, the partial panel can be moved more easily.

(6)
The push-out mechanism connects the door body and the partial panel and has a link mechanism that can move the partial panel in the vertical vertical direction. The partial panel protrudes while moving vertically upward or downward by the link mechanism. It may be held freely.

  In this case, the partial panel protrudes while moving in the vertical direction by the link mechanism that can move in the vertical vertical direction, and the sealing material provided on the partial panel is in close contact with the doorway. As a result, airtightness can be easily and reliably increased.

(7)
The push-out mechanism connects the door body and the partial panel, and has a link mechanism that can move the partial panel in the horizontal direction, and the partial panel can be protruded while being moved in the horizontal direction by the link mechanism. Good.

  In this case, the partial panel is projected while moving in the horizontal direction by the link mechanism that can move in the horizontal direction, and the sealing material provided on the partial panel is in close contact with the doorway. As a result, airtightness can be easily and reliably increased.

(8)
The push-out mechanism may include a rod-shaped member that reciprocates as the door body moves in the horizontal direction, and conversion means that converts the reciprocating motion of the rod-shaped member into driving of the link mechanism.

  In this case, the rod-shaped member reciprocates as the door moves, and the reciprocating motion of the rod-shaped member is used for driving the link mechanism by the converting means. As a result, two drive sources, a drive source for moving the door body in the horizontal direction and a drive source for projecting the partial panel of the door body, are unnecessary, and only one drive source for moving the airtight door in the horizontal direction is realized. can do. Therefore, the cost of the drive source can be reduced. Alternatively, rail bending can be eliminated. Furthermore, an airtight door can be provided by replacing the door body of an existing door without newly replacing standard rails, hardware, or the like.

  By replacing the conventional door with the airtight door according to the present invention, the airtightness can be easily increased. That is, there is no need to bend the rail member in order to move the door body toward the doorway side while sliding and opening the door body, and a standard rail member and a hardware member such as a hanger can be used. As a result, since it is not influenced by the position adjustment between the rail member and the doorway at the time of installation, low cost can be realized while maintaining high airtightness with a single drive source.

Embodiments according to the present invention will be described below.
(First embodiment)
FIG. 1 is a schematic structural diagram showing an example of an airtight door device 200 having an airtight door 100 according to an embodiment of the present invention. FIG. 1A shows a front view of the hermetic door device 200 having the hermetic door 100, and FIG. 1B shows a side cross section of the hermetic door device 200 having the hermetic door 100.

  As shown in FIGS. 1 (a) and 1 (b), in the hermetic door device 200, the hermetic door 100 is suspended from a rail 300 disposed above (a member suspended in a suspended state). It is installed to be movable in the horizontal direction via Further, one drive source 350 is provided for opening and closing the hermetic door 100, and in this embodiment, for example, a brushless DC motor or the like is used. The connection member 320 is moved by the action of the drive source 350, and the suspension member 310 connected to the connection member 320 is moved. By moving the suspension member 310, the hermetic door 100 is moved in the horizontal direction.

  A protruding rod 110 is provided on the upper side of the hermetic door 100 so as to extend substantially parallel to the moving direction of the hermetic door 100. Therefore, when the hermetic door 100 is closed, the protruding rod 110 comes into contact with the wall surface W and the protruding amount decreases. On the other hand, when the airtight door 100 is in the open state, the protruding rod 110 does not contact the end surface of the wall surface W, and the protruding amount increases. Details of the movement of the protruding rod 110 will be described later.

  Next, FIG. 2 is a schematic structural diagram for explaining an example of the structure of the hermetic door 100 of FIG.

  As shown in FIG. 2, the airtight door 100 mainly includes a protruding bar mechanism 115, a link 121, a moving door 150, and an outer frame member 160.

  A rectangular concave shape 162 is formed inside the outer frame member 160 of the plate-like member, and the concave shape 162 is a shape that can accommodate the movable door 150. In the present embodiment, the movable door 150 is accommodated in the concave shape 162. However, the present invention is not limited to this, and the outer frame member 160 and the movable door 150 may be arranged in an overlapping manner. In addition, six links 121 are provided between the concave shape 162 of the plate member and the movable door 150. The two links 121 are disposed so as to be able to support left and right ends (both ends in the moving direction of the door) of the upper part of the moving door 150. Further, the other two links 121 are disposed so as to be able to support the left and right ends of the middle part of the movable door 150. The remaining two links 121 are disposed so as to be able to support the left and right ends of the lower part of the movable door 150. A protruding bar mechanism 115 including the protruding bar 110 described above is disposed at the upper end of the outer frame member 160. Details of the protruding bar mechanism 115 will be described later.

  Next, FIGS. 3 and 4 are schematic enlarged views showing an example of the protruding bar mechanism 115 of the hermetic door 100 of FIG. FIG. 5 is a schematic longitudinal sectional view showing an example of the protruding bar mechanism 115 of the hermetic door 100 of FIG. FIG. 3 shows a state where the protruding bar mechanism 115 of the hermetic door 100 of FIG. 2 is not in contact with the end face of the wall surface W. 4 shows a state where the protruding bar mechanism 115 of the hermetic door 100 of FIG. FIG. 5A shows a state where the hermetic door 100 is fully opened (in a state where it is not in contact with the end face of the wall surface W). FIG. 5B shows a state in which the hermetic door 100 is fully closed (a state in which the protruding bar mechanism 115 is in contact with the end surface of the wall surface W).

  As shown in FIGS. 3 and 4, the protruding rod mechanism 115 includes two protruding rods 110, two springs 111, two taper members 112, one on each of the left and right sides, and two one each on the upper and lower sides. And a pair of roller members 113.

  Next, as shown in FIGS. 3 and 4, the protruding rod 110 in the protruding rod mechanism 115 is provided by being biased by a spring 111 in a direction protruding from the outer frame member 160 of the hermetic door 100. Further, the protruding rod holding member 190 is fixed to the outer frame member 160 in order to hold the spring bias.

  Here, as shown in FIGS. 3 and 4, the arrangement of the roller member 113 and the taper member 112 will be described. First, two taper members 112 are fixed to the protruding rod 110, and a roller member 113 is fixed to the movable door 150. The taper member 112 has two inclined surfaces that gradually increase in the vertical direction from the protruding side of the protruding rod 110 toward the opposite direction to the protruding side. One of the two inclined surfaces is a surface located on the upper side of the taper member 112 and facing upward. The other inclined surface is a surface located below the taper member 112 and facing downward. One roller member 113 of the pair of roller members 113 is disposed so as to contact the upper inclined surface of the taper member 112 from above. In addition, the other roller member 113 of the pair of roller members 113 is disposed so as to contact the lower inclined surface of the taper member 112 from the lower side.

  Also, as shown in FIGS. 3 and 4, the roller member 113 is provided on the upper side of the movable door 150 in a pair of left and right sides (two on the left side and two on the right side). As shown in FIG. 5, the roller member 113 is provided so as to extend in a direction perpendicular to the axial direction of the protruding rod 110 (the depth direction of the movable door 150). As described above, the roller member 113 is provided to move while rolling on the surface of the tapered member 112 inclined with respect to the axial direction of the protruding rod 110. Further, the taper member 112 is formed to have a width larger than the protruding amount of the moving door 150 in the protruding direction of the moving door 150.

  Next, the function of the protruding rod 110 will be described. In the following description, the case where the airtight door 100 shifts to a fully closed state will be described first. And the case where the airtight door 100 transfers to a full open state is demonstrated following the description.

  First, as shown in FIG. 3, a case where the protruding rod 110 protrudes from the outer frame member 160 due to the bias of the spring 111 will be described. In this case, the portion of the taper member 112 provided on the protruding rod 110 that is at the highest position in the vertical direction is sandwiched between the pair of roller members 113. That is, similarly in FIG. 5A, the roller member 113 is present at the highest position in the vertically upward direction. That is, the roller member 113 is supported by the taper member 112 so that the movable door 150 does not move vertically downward. As a result, the movable door 150 is housed in the concave shape 162 of the outer frame member 160.

Next, in the process in which the hermetic door 100 shifts to the fully closed state, as shown in FIG. 4, the tip of the protruding rod 110 contacts the end surface of the wall surface W, and the protruding amount gradually increases against the bias of the spring 111. A case where the number decreases will be described. In this case, the roller member 113 moves vertically downward along the taper shape of the taper member 112 fixed to the protruding rod 110. In other words, the pair of roller members 113 moves vertically downward with the taper shape held by the dead weight of the movable door 150.
Here, since the taper member 112 is formed in a taper shape having a width equal to or greater than the protruding amount of the movable door 150 with respect to the depth direction of the outer frame member 160, the pair of roller members 113 moves in the depth direction. However, the state in which the tapered shape is sandwiched between the pair of roller members 113 can be maintained. As a result, the movable door 150 is protruded from the concave shape 162 of the outer frame member 160. In this case, due to the action of the link 121, the movable door 150 is stably moved in the vertically downward diagonal direction.

  Then, the case where the airtight door 100 transfers to a fully open state from a fully closed state is demonstrated. In this case, according to the movement of the hermetic door 100, the protruding rod 110 on which the urging force in the protruding direction from the spring 111 acts moves relative to the roller member 113 in the protruding direction. When the movement of the hermetic door 100 in the opening direction exceeds a predetermined amount, the tip of the protruding rod 110 is separated from the end surface of the wall surface W. At this time, the pair of roller members 113 are moved vertically upward while sandwiching the tapered shape of the tapered member 112 provided on the protruding rod 110. As a result, the movable door 150 is accommodated in the concave shape 162 of the outer frame member 160. In this case, the movable door 150 is stably moved in the diagonally upward direction by the action of the link 121.

  In the present embodiment, the roller member 113 is provided on each of the upper and lower sides. However, if the movable door 150 is provided so as to be urged vertically downward with respect to the outer frame member 160, the upper side is provided. It doesn't matter if only Although the movable door 150 is moved vertically downward relative to the outer frame member 160, the present invention is not limited to this, and the movable door 150 may be moved vertically upward or horizontally. In addition, when the movable door 150 protrudes while being moved vertically downward as in this embodiment, gravity applied by the dead weight of the movable door 150 can be used as a pressing force against the wall surface W. The airtightness can be easily improved as compared with the case of moving or the case of moving in the horizontal direction described later.

  Next, FIG. 6 is a schematic perspective view showing an example of the state of the hermetic door 100 shown in FIGS. 3 to 5 from the fully open state to the fully closed state. FIG. 7 is a schematic enlarged view in which a partial longitudinal section of the hermetic door 100 of FIG. 5 is enlarged. FIG. 8 is a schematic enlarged view in which a partial longitudinal section of the hermetic door 100 of FIG. 5 is enlarged. FIG. 9 is a schematic enlarged view showing a partial cross section of the hermetic door 100 of FIG.

  6A to 9A show a state where the hermetic door 100 is open, and FIG. 6B shows a case where the hermeticity is enhanced by the hermetic door 100. Hereinafter, the airtight door 100 in the open state is referred to as the airtight door 100, and the airtight door 100 in the closed state is referred to as the airtight door 100a.

  As shown in FIGS. 6 (a), 7 (a), 8 (a), and 9 (a), when the airtight door 100 is open, that is, when the airtightness is not maintained, the airtightness is not maintained. The movable door 150 is maintained in a state where it does not protrude from the concave shape 162 of the outer frame member 160 of the door 100. On the other hand, as shown in FIGS. 6B, 7B, 8B, and 9B, when the airtight door 100a is closed, that is, when the airtightness is maintained. The movable door 150 is maintained in a state of protruding from the concave shape 162 of the outer frame member 160 of the airtight door 100a.

  First, as shown in FIGS. 6 (a), 7 (a), 8 (a), and 9 (a), the protruding rod 110 is brought into contact with the end surface of the wall surface W when the airtight door 100 is opened. First, the protruding rod 110 protrudes. In this state, the roller member 113 holds the taper member 112 at the highest position (the highest position in the vertical direction) on the inclined surface of the taper member 112. At this time, the movable door 150 is housed in the outer frame member 160.

  Subsequently, as shown in FIG. 6B, FIG. 7B, FIG. 8B, and FIG. 9B, as the airtight door 100 shifts from the open state to the closed state, the protruding rod 110 Comes into contact with the end face of the wall surface W, against the bias of the spring 111, the amount of protrusion of the protrusion rod 110 decreases, and the taper member 112 moves. Then, the roller member 113 moves along the lowest position from the highest position in the vertical direction of the taper member 112. As the roller member 113 moves, the moving door 150 is moved vertically downward by its own weight. As a result, the movable door 150 is protruded from the concave shape 162 of the outer frame member 160. In this projecting movement, the movable door 150 is stably projected from the outer frame member 160 by the rotational movement of the link 121.

  Here, the airtightness will be described in detail. As shown in FIG. 6, the moving door 150 is provided with a seal member 170. When the protruding amount of the protruding rod 110 is reduced and the taper member 112 moves, the roller member 113 moves vertically downward (see FIG. 8), and the link 121 rotates (see FIG. 7). Thereby, the movable door 150 is pushed out from the concave shape 162 of the outer frame member 160 in a vertically downward oblique direction. In this case, as shown in FIGS. 7 to 9, the seal member 170 is pressed against the wall surface W, and the airtightness is improved.

  That is, at the lower part of the hermetic doors 100 and 100a, as shown in FIGS. 7A and 7B, the hermetic door 100 moves along the guide rail 400, and the movable door 150 is pushed in an obliquely downward vertical direction. As a result, the link 121 is rotationally moved. In this case, the seal member 170 provided on the lower surface of the movable door 150 is pressed against the wall surface W, and airtightness is improved.

  Moreover, in the upper part of the airtight doors 100 and 100a, as shown in FIGS. 8A and 8B, the movable door 150 is provided in the upper part of the movable door 150 by being pushed vertically and obliquely. The seal member 170 is pressed against the wall surface W, and airtightness is improved.

  Further, in the vertical direction of the hermetic doors 100 and 100a, as shown in FIGS. 9A and 9B, the sealing member 170 provided on the movable door 150 is pressed against the wall surface W, thereby improving the hermeticity. It is done.

With the above configuration, in the airtight door 100 according to the present invention, the airtightness can be easily increased by replacing the conventional door with the airtight door 100 according to the present invention. That is, there is no need to bend the rail member in order to move the airtight door 100 toward the doorway while sliding and opening the hermetic door 100, and a standard rail member and a hardware member such as a hanger can be used. As a result, since the position adjustment between the rail member and the doorway at the time of installation is not affected, it is possible to realize low cost while maintaining high airtightness with one drive source 350.
Further, the movable door 150 protrudes while moving in the vertical direction by the link 121 movable in the vertical vertical direction, and the seal member 170 provided on the movable door 150 is in close contact with the doorway. As a result, airtightness can be easily and reliably increased.

  Further, the protruding bar mechanism 115 includes a protruding bar 110, a spring 111, a taper member 112, and a roller member 113. According to this configuration, the spring 111 is installed on the projecting rod 110 by the biasing force of the spring 111 acting on the projecting rod 110 and the pressing force from the wall surface acting on the projecting rod 110 in the direction opposite to the biasing force. The positional relationship between the taper member 112 and the roller member 113 installed on the movable door 150 is changed. Thereby, the movable door 150 can be protruded from the recessed shape 162, or can be accommodated.

  Further, in the airtight door 100 according to the present embodiment, the weight of the movable door 150 is supported by the single spring 111 and the number of parts is reduced to reduce the cost. However, the present invention is not limited to this. The fail-safe property may be improved by supporting the movable door 150 with a plurality of springs 111.

  Next, the function of the protruding rod 110 will be described. In the following description, the case where the airtight door 101 shifts to a closed state will be described first. And the case where the airtight door 101 transfers to an open state is demonstrated following the description.

  First, a case where the protruding rod 110 protrudes from the outer frame member 160 due to the bias of the spring 111 will be described. In a state where the protruding rod 110 protrudes from the outer frame member 160 by the bias of the spring 111, the movement in the protruding direction of the taper member 112 fixed to the protruding rod 110 is restricted by the protruding rod holding member 190. The movement of the protruding rod 110 in the protruding direction is restricted. In this state, the minimum tapered portion (root) of the taper member 112 provided on the protruding rod 110 is in a position in contact with the roller member 113. That is, in this state, the roller member 113 exists at the highest position in the vertical direction. As a result, no force is transmitted to the link 122, and the movable door 150 is accommodated in the concave shape 162 of the outer frame member 160 by the bias of the spring 120.

  Next, when the tip of the projecting rod 110 contacts the end surface of the wall surface W and the projecting amount gradually decreases against the bias of the spring 111, the taper member 112 provided on the projecting rod 110 follows the taper shape. Thus, the roller member 113 is moved vertically downward. As a result, force is transmitted to the link 122, and the movable door 150 is projected from the concave shape 162 of the outer frame member 160 against the bias of the spring 120.

  Subsequently, when the tip of the projecting bar 110 is separated from the end surface of the wall surface W and the bias of the spring 111 is applied, the roller member 113 moves vertically upward along the taper shape of the taper member 112 provided on the projecting bar 110. Moved. As a result, no force is applied to the link 122, and the movable door 150 is accommodated in the concave shape 162 of the outer frame member 160 by the bias of the spring 120. If the movable door 150 is configured to protrude while being moved vertically downward in this way, gravity can be used as a pressing force against the wall surface W. The airtightness can be improved as compared with the case of moving to.

  Next, FIG. 13 is a schematic side view showing the operation of the drive source 350 and the link 122 of the hermetic door 101. FIG. 14 is a schematic perspective view showing an open / closed state of the hermetic door 101 shown in FIG.

  15 is a schematic enlarged view in which a partial vertical section of the hermetic door 101 in FIG. 13 is enlarged. FIG. 16 is a schematic enlarged view in which a partial vertical cross section of the hermetic door 101 in FIG. 13 is enlarged. FIG. 17 is a schematic enlarged view showing a partial cross section of the hermetic door 101 of FIG.

  13A to 17A show a state where the airtight door 101 is open, and FIG. 13B shows a case where the airtightness is enhanced by the airtight door 101. Hereinafter, the airtight door 101 in the open state is referred to as the airtight door 101, and the airtight door 101 in the closed state is referred to as the airtight door 101a.

On the other hand, as shown in FIGS. 13B and 14B, when the airtight door 101a is closed, that is, when the airtightness is maintained, the concave shape 162 of the outer frame member 160 of the airtight door 101a. The movable door 150 is maintained in a protruding state.

  First, as shown in FIG. 13A, FIG. 14A, FIG. 15A, FIG. 16A, and FIG. The protruding rod 110 protrudes without contacting the end face of W. Therefore, the roller member 113 comes into contact with the minimum taper shape portion (root) of the taper member 112, and the movable door 150 is housed in the outer frame member 160 by the bias of the spring 120.

  Subsequently, as shown in FIG. 13B, FIG. 14B, FIG. 15B, FIG. 16B, and FIG. 17B, the airtight door 101a shifts from the open state to the closed state. Accordingly, the protruding rod 110 contacts the end surface of the wall surface W, the protruding amount of the protruding rod 110 decreases, and the taper member 112 moves. Then, the roller member 113 relatively moves along the inclined surface of the taper member 112 from the minimum taper shape portion (root) of the taper member 112 to the maximum taper shape portion. That is, when the taper member 112 moves against the biasing force of the spring 111, the roller member 113 receives a downward biasing force from the inclined surface of the taper member 112. As a result, the roller member 113 is moved downward against the biasing force of the spring 120 acting via the link 122. As a result, the movable door 150 is protruded from the concave shape 162 of the outer frame member 160.

When the protruding amount of the protruding rod 110 is reduced and the taper member 112 moves, the roller member 113 is pushed vertically downward as shown in FIG. 15B, and the link 122 rotates. Thereby, the movable door 150 is pushed out from the concave shape 162 of the outer frame member 160 in a vertically downward oblique direction. Further, since the pushing force is stronger than the urging force of the spring 120, the movable door 150 is smoothly moved in the vertically downward diagonal direction. In this case, the seal member 170 is pressed against the wall surface W, and airtightness is improved.

  Further, at the lower part of the hermetic doors 101 and 101a, as shown in FIGS. 16A and 16B, the hermetic door 101 moves along the guide rail 400, and the movable door 150 is pushed out in an obliquely downward vertical direction. As a result, the link 122 is moved against the bias of the spring 120. In this case, the seal member 170 provided on the lower surface of the movable door 150 is pressed against the wall surface W (the surface on which the guide rail 400 is installed), and airtightness is improved.

  Further, in the vertical direction of the hermetic doors 101 and 101a, the sealing member 170 provided on the movable door 150 is pressed against the wall surface W as shown in FIGS. It is done.

With the above configuration, in the airtight door 101 according to the second embodiment, the airtightness can be easily increased by replacing the conventional door with the airtight door 101 according to the present invention. That is, there is no need to bend the rail member in order to move the hermetic door 101 toward the door side while sliding and opening the hermetic door 101, and a standard rail member and a hardware member such as a hanger can be used. As a result, since the position adjustment between the rail member and the doorway at the time of installation is not affected, it is possible to realize low cost while maintaining high airtightness with one drive source 350.
Further, the movable door 150 protrudes while moving in the vertical direction by the link 122 movable in the vertical vertical direction, and the seal member 170 provided on the movable door 150 is in close contact with the door. As a result, airtightness can be easily and reliably increased.

  Further, the protruding bar mechanism 116 includes the protruding bar 110, the taper member 112, and the roller member 113, so that the moving door 150 is opposed to the spring 120 and the link 122 that bias the moving door 150 into the concave shape 162.
