Description

  The present invention relates to a gap shielding structure for a door.

  Generally, a toilet booth or the like installed in a public place has an inward opening door to prevent a collision with a person due to an unexpected opening. However, there is a problem that the door that opens inward cannot be quickly opened even in the unlocked state due to the user falling into the door opening space. As a solution to such a problem, many techniques have been disclosed that enable the door to be opened outside in an emergency, while ensuring the function of closing the gap between the door and the sleeve wall. For example, an opening / closing structure of a door for a toilet booth or a shower booth disclosed in Patent Literature 2, in which a finger jamming prevention edge body of Patent Literature 1 configured to get over a blindfold protrusion, a sleeve wall edge member deformed by pressing force, and a blindfold are provided. Emergency unlocking mechanism of Patent Literature 3 in which the universal pin opens the door in case of emergency, Door frame for toilet booth of Patent Literature 4 in which the door presses a movable door stop, and the projecting piece is elastically deformed to the indoor side to be emergency. In this case, for example, there is a shielding structure of an inward opening door disclosed in Patent Document 5 in which the door can be opened to the outdoor side.

JP 2013-124481 A (FIG. 2, paragraph 0018) JP 2013-124485 A (FIG. 5, paragraphs 0019 and 0027) JP 2014-141871 A (FIG. 4, paragraph 0020) Japanese Patent Application Laid-Open No. 10-28013 (FIG. 1, paragraph 0015) JP-A-2002-121973 (FIG. 1, paragraph 0025)

  However, the opening / closing structure of the door body for preventing finger stuffing in Patent Document 1 and the door for a toilet booth or shower booth in Patent Document 2 requires that a molded article having a complicated shape be provided on both end surfaces of the door and the sleeve wall. Cost increases. Also, the emergency unlocking mechanism of Patent Document 3 and the door frame for a toilet booth of Patent Document 4 require movable parts, so that the structure is complicated, the cost is high, and the operation reliability is ensured for a long period of time. difficult. In addition, since the shield structure of the inward-opening door disclosed in Patent Document 5 is assembled from a plurality of parts, the structure is complicated, the cost is increased, and parts management is complicated. In addition, when the main member is provided on the sleeve wall side, the gap shielding structure is always visible and the appearance is deteriorated.

  The present invention has been made in view of the above circumstances, and its object is to enable blindfolding of a gap with a simple shape, to allow the door to pass smoothly at the time of emergency opening, and not to lower the appearance. An object of the present invention is to provide a door gap shielding structure.

Next, means for solving the above problems will be described with reference to the drawings corresponding to the embodiments.
The door gap shielding structure according to claim 1 of the present invention includes a wall panel 13 defining a private room 21 having an entrance 23,
A door 15 that is rotatably supported on the door panel side on the wall panel side and that normally opens the interior side of the private room 21 to open the entrance 23,
A sleeve panel 17 which is connected to the wall panel 13 and faces the doorway 23, and a door stop edge 25 faces a door edge 27 of the door 15 with a gap 29;
A flexible blindfold that is attached to a position on the surface of the door edge 27 that is biased toward the indoor side, extends vertically above and below the door edge, and intercepts the gap 29 and projects toward the door stop edge 25. 19,
It is characterized by having.

  In the gap shielding structure of the door, the blind piece 19 is formed by projecting toward the door stop edge 25, extending vertically above and below the door tip, and having a flexible, for example, band-shaped fin member. I have. Thereby, the gap clearance structure of the door can be a simple structure in which the blindfold piece 19 having a simple shape is attached to the indoor side of the door edge 27. In addition, in the door gap shielding structure, when the door is closed, the gap 29 between the door stop edge 25 and the door edge 27 is blocked by the blind piece 19, so that the inside of the private room 21 cannot be seen from the outside through the gap 29. Further, even if the door 15 is opened to the outdoor 47 side at the time of emergency opening, the blindfold piece 19 can be easily deformed by receiving the reaction force from the door stop edge 25. Thereby, the blindfold piece 19 can suppress the resistance at the time of interference with the door stop edge 25, and can realize a smooth door opening at the time of emergency opening. Further, in the gap shielding structure of the door, the blind piece 19 is mounted at a position on the surface of the door edge 27 that is offset toward the indoor side. Normally, the door 15 is in a state in which the door is opened toward the room 33 of the private room 21, that is, a so-called normally open state. For this reason, the door 15 is located at an open position where the entrance 23 is opened, and the blindfold 19 is located at a position closer to the wall panel 13 side, so that it is difficult to be visually recognized from the entrance 23 side. As a result, in the door gap shielding structure, extra members and structural portions are not normally visible, and the door 15 and the entrance 23 have a neat appearance. In addition, there is a normally closed state in which the door 15 closes the doorway 23. In this case, when the inside of the private room 21 is viewed from the doorway 23, that is, toward the door 15, the gap 29 is closed. The blind piece 19 is positioned so as to shield.

The gap shielding structure for a door according to claim 2 of the present invention is the door gap shielding structure according to claim 1,
The blind piece 75 projects substantially parallel to the inner surface of the door 15,
The door stop edge 77 has a convex curved surface 49 having a vertex substantially at the center in the thickness direction of the sleeve panel 17 at least on the indoor side.

In the door gap shielding structure, the blind piece 75 projects substantially parallel to the inner surface of the door 15. That is, the blindfold pieces 75 project almost straight from the door edge 79 toward the door stop edge 77. On the other hand, the door stop edge 77 has, at least on the indoor side, a convex curved surface 49 having a vertex substantially at the center of the sleeve panel 17 in the thickness direction. That is, the door stop edge 77 is a curved surface (R surface) from which corners are removed at least on the indoor side from the vertex of the convex curved surface 49. In this curved surface, the outside of the room from the top and the inside of the room from the top are the hem side of the convex curved surface 49 and are hidden (visible). That is, it cannot be seen from the gap 29. The blindfold piece 75 is arranged such that its tip is close to the blindfold (the hem side of the convex curved surface 49) where the corner is removed, and projects so as to block the line of sight 69, that is, so as to cross the gap 29. Protrude. As a result, the gap 29 is blocked by the blind piece 75, so that the inside of the private room 21 cannot be seen from the outside through the gap 29.
In this door gap shielding structure, since the door stop edge 77 has the convex curved surface 49, the convex curved surface 49 can be hidden, so that the cover of the blindfold piece 75 can be easily secured with a simple structure. In addition, the blind piece 75 can be formed in a simple linear shape with the projecting direction being substantially parallel to the inner surface of the door 15, and has a neat appearance.

A door gap shielding structure according to claim 3 of the present invention is the door gap shielding structure according to claim 2,
The curvature circle Cur forming the convex curved surface 49 is characterized in that the diameter D is larger than the plate thickness T of the sleeve panel 17 and smaller than twice the plate thickness T of the sleeve panel 17.

  In the door gap shielding structure, the convex curved surface 49 is not chipped due to the diameter D of the curvature circle Cur forming the convex curved surface 49 being smaller than the plate thickness T of the sleeve panel 17. Also, the flattening of the convex curved surface 49 due to the diameter D of the curvature circle Cur forming the convex curved surface 49 being larger than twice the thickness T of the sleeve panel 17 is suppressed. That is, disappearance of blindness can be prevented.

  The door gap shielding structure according to claim 4 of the present invention is the door gap shielding structure according to claim 1, wherein the blind piece 19 is inclined in a direction toward the door opening side of the door 15. It is characterized by being provided.

  In this door gap shielding structure, the blind piece 19 is inclined in a direction toward the door 15 to open. Here, a imaginary horizontal line 71 passing through a point where the blind piece 19 protrudes from the surface of the door edge 27 and parallel to the inner surface of the door 15 is considered. The blindfold piece 19 is inclined (inclined) toward the room 33 with a predetermined angle θ with respect to the virtual line 71. The door 15 is opened to the outdoor 47 side at the time of emergency opening. The blindfold piece 19 is inclined in the direction opposite to the door opening direction at the time of emergency opening. As a result, the blindfold 19 can be easily deformed in a further inclined direction at the time of emergency opening.

The door gap shielding structure according to claim 5 of the present invention is the door gap shielding structure according to claim 1 or 4,
The blindfold piece 19 has a bent portion 73 at the end thereof bent in a direction toward the door opening side of the door 15.

  In this door gap shielding structure, the blind piece 19 has a bent portion 73 at the tip. The blindfold piece 19 having the bent portion 73 is substantially J-shaped, substantially L-shaped, or substantially F-shaped in plan view. That is, the bent portion 73 at the tip is formed by bending further in the same direction with respect to the inclined blindfold piece 19. Therefore, the bent portion 73 does not hinder easy deformation of the blindfold piece 19 in the inclined direction when the blindfold piece 19 moves to the outdoor side during emergency opening. Further, the blind piece 19 has the increased rigidity due to the formation of the bent portion 73. Thus, the blindfold 19 has flexibility and allows easy deformation, but hardly causes sagging or kinking, hardly collapses, and hardly generates a gap due to deformation.

The door gap shielding structure according to claim 6 of the present invention is the door gap shielding structure according to any one of claims 1, 4, and 5,
The door stop edge 25 is formed with a concave portion 55 into which the tip of the blindfold piece 19 enters.

  In this door gap shielding structure, the blind piece 19 can be formed to have a longer protruding length than the case where there is no concave portion 55, as much as the blind piece 19 enters the concave portion 55 of the door stop edge 25. The blind piece 19 having a long protruding length has a smaller local deformation amount at the time of emergency opening than the blind piece 19 having a short protruding length. Thus, the blind piece 19 can be deformed with an allowance for the elastic limit at the time of emergency opening. That is, the blind piece 19 can reduce the load at the time of deformation, and can hardly cause plastic deformation.

A door gap shielding structure according to claim 7 of the present invention is the door gap shielding structure according to any one of claims 1 to 6,
The blindfold 19 is
A base 63 extending vertically over the door and attached to the door edge 27;
A fin portion 65 extending from the base portion 63 and projecting toward the door stop edge 25 while blocking the gap 29, and formed of a material softer than the base portion 63;
It is characterized by being formed by

  In this door gap shielding structure, the blind piece 19 includes a relatively hard base 63 and a fin 65 that is softer than the base 63. The blind piece 19 has, for example, a dovetail groove 67 formed in the up-down edge formed on the door edge 27 and a base 63 formed in substantially the same cross-sectional shape as the dove groove 67. Insert from and attach. Since the base portion 63 is hard, the blindfold piece 19 maintains straightness, and the workability in attaching to the door edge 27 is improved. In addition, since the blind base 19 has the hard base 63 held by the door edge 27, the mounting strength to the door edge 27 is greater than when the base 63 is soft. Since the fin portion 65 is soft, the blindfold piece 19 to which the base 63 is securely fixed can be easily deformed by the reaction force from the door stop edge 25 at the time of emergency opening.

  ADVANTAGE OF THE INVENTION According to the clearance gap shielding structure of the door of Claim 1 which concerns on this invention, it can blindfold a clearance gap with a simple shape, can pass a door smoothly at the time of an emergency opening, and also reduces appearance. Absent.

  According to the door gap shielding structure according to claim 2 of the present invention, the blindfolding piece protrudes substantially parallel to the inner surface of the door, and the door stop edge is formed by a convex curved surface having a vertex substantially at the center in the door thickness direction. Therefore, the gap shielding structure can be simplified, and the blind piece can be hardly caught by the door stop edge.

  According to the door gap shielding structure according to the third aspect of the present invention, it is possible to reliably ensure the line-of-sight shielding effect.

  According to the door gap shielding structure according to claim 4 of the present invention, the blindfold piece can be easily bent at the time of emergency opening.

  According to the door gap shielding structure according to claim 5 of the present invention, it is possible to maintain the shape for a long period of time by preventing the blind piece from being bent by the bent portion, and also to prevent the generation of a gap due to deformation and suppress light leakage. it can.

  According to the door gap shielding structure according to claim 6 of the present invention, the recessed portion is formed at the opposing door stop edge, so that the projection length of the blindfold piece can be formed long, and the blindfold piece can be further extended at the time of emergency opening. It is hard to slip and can be easily bent.

You can also.

FIG. 3 is a perspective view of a main part of a gap shielding structure in which a door stop member 35 is provided at an upper portion of the door 15 on the indoor side.
The door stop member 35 normally closes the door, hits the sleeve panel 17, and regulates opening of the door 15 outside (outdoor). The door stop member 35 can slide downward when pushed down from above (indicated by a broken line in FIG. 3). The door stop member 35 has a mechanism that allows the door stop member 35 to swing (in the direction of the arrow B in FIG. 3) into the room 33 at the sliding position downward.

FIG. 4 is an operation explanatory view of the door stop member 35 at the time of emergency opening.
The door stop member 35 releases the regulation of the door 15 by sliding downward at the time of emergency opening, and allows the door 15 to open outward (in the direction of the arrow C in FIG. 4).

FIG. 5 is a cross-sectional plan view of a main part of the toilet booth 11 in which the entrance 23 is closed by the door 15.
The door 15 has a bulging portion in which the door edge 27 is vertically continuous. The bulging portion is formed in a convex curved surface 49 having a ridge at a substantially center in the door thickness direction, that is, in a so-called kamaboko shape. The door edge 27 has the convex curved surface 49 to narrow the gap 29 between the door edge 27 and the door stop edge 25 provided on the sleeve panel 17. In the first embodiment, the door edge 51 of the door 15 is also formed to have a similar convex curved surface 49.

  The door stop edge 25 is provided on the end face of the sleeve panel 17 facing the door edge 27. The door stop edge 25 is formed with a raised portion 53 protruding in a direction in which the approximate center of the door thickness direction approaches the door edge 27. The door stop edge 25 has a concave portion 55 at a position where the raised portion 53 is located outside the room on the indoor side and the outdoor side. The door stop edge 25 is formed in such a shape that the concave portion 55 on the indoor side and the concave portion 55 on the outdoor side are symmetrical with the raised portion 53 interposed therebetween. Thereby, the door stop edge 25 can correspond to any of the left and right opening of the door 15. The function of the recess 55 will be described later.

  In the first embodiment, the sleeve panel 17 facing the door edge 51 is provided with a door edge 57. The door bottom facing edge 57 has a concave curved surface 59 along the convex curved surface 49 of the door bottom edge 51. The concave curved surface 59 is formed only from the approximate center in the door thickness direction to the outdoor side, and is not formed on the indoor side. Accordingly, the door 15 is ensured to have a larger opening angle to the indoor side in a normal state than the opening angle to the outdoor side in an emergency. The door bottom facing edge 57 has a concave curved surface 59 to bend while narrowing the gap with the door bottom edge 51, and as a blindfold to prevent the interior 33 from being seen from between the door bottom edge 51 and the sleeve panel 17. Function.

  The door edge 27, the door stop edge 25, the door bottom edge 51, and the door bottom facing edge 57 are formed in a straight strip shape extending over the top and bottom of the door and the door bottom. The door edge 27, the door stop edge 25, the door end edge 51, and the door end facing edge 57 are made of, for example, an aluminum shape. As shown in FIG. The door 15 and the sleeve panel 17 are fixed to the opening. A plurality of fixing screws 61 are provided at predetermined intervals above and below the door tip and the door bottom.

  The blindfold piece 19 is attached to the surface of the door edge 27 at a position offset toward the indoor side, and extends up and down the door. The blindfold 19 narrows and blocks the gap 29 by projecting toward the door stop edge 25. The blinds 19 are made of rubber, elastomer, or soft resin, and have flexibility.

  The blindfold 19 has a base 63 and a fin 65. The base 63 extends over the top and bottom of the door and is attached to the door edge 27. The base 63 has a T-shaped cross section orthogonal to the extending direction. The fin portion 65 extends over the top and bottom of the door. The fin portion 65 protrudes from the base portion 63 toward the door stop edge 25, and narrows the gap 29. The fin portion 65 is formed of a material softer than the base portion 63. On the other hand, the base 63 is formed of a material harder than the fin 65. The base portion 63 and the fin portion 65 may be integrally formed of the same material having different hardness, or may be formed separately and joined.

  In the door edge 27, a dovetail groove 67 with which the base 63 is engaged is formed on the indoor side of the convex curved surface 49. The blind piece 19 is inserted into a dovetail groove 67 extending in the vertical direction formed in the door edge 27 and a base 63 having substantially the same cross-sectional shape as the dove groove 67 is inserted from the upper end or lower end of the door edge 27. And attached. The blindfold 19 is fixed at a position (surface) where the base 63 is shifted toward the normal opening direction at the edge of the door 15. The blind piece 19 does not come into contact with or contact the door stop edge 25 when the door 15 is normally opened and closed while maintaining the separation distance from the door stop edge 25. The blind piece 19 has the tip of the fin portion 65 extending into the gap 29 to block the line of sight 69 in the indoor and outdoor directions.

  The blindfold piece 19 is inclined in a direction toward the door 15 to open. Here, in FIG. 5, consider a virtual virtual line 71 that passes through the point where the blind piece 19 protrudes from the surface of the door edge 27 and is parallel to the inner surface of the door 15. The blindfold 19 has a predetermined angle θ with respect to the imaginary line 71 and is inclined (inclined) toward the indoor side. The door 15 is opened to the outside at the time of emergency opening. The blindfold 19 is inclined in the direction opposite to the door opening direction at the time of emergency opening, that is, in the indoor side.

  The blindfold piece 19 has a bent portion 73 at the end thereof bent in a direction toward the door opening side of the door 15. The blindfold 19 having the bent portion 73 has a substantially J shape, a substantially L shape or a substantially F shape in plan view. That is, the blindfold piece 19 has the bent portion 73 that bends in the same direction with respect to the inclined tip.

  The blindfold 19 may omit the bent portion 73.

  The blind piece 19 is detachable from the door edge 27 and can be replaced. That is, the blind piece 19 can be replaced for damage or stain. The blindfold 19 may be damaged at the time of emergency opening. In that case, the blindfold 19 is replaced. In the replacement method, the blindfold piece 19 is pulled out from the longitudinal end, for example, the upper end of the dovetail groove 67 formed in the door edge 27 made of an aluminum mold, and a new blindfold piece 19 is inserted and fixed. A cap is fitted at an end, for example, an upper end of the door edge 27. The cap is removed and the dovetail groove 67 is opened for replacement. The blindfold piece 19 has hardness enough to ensure that the base 63 can be easily pushed in, or has hardness enough to maintain straightness. Accordingly, the base portion 63 of the blindfold piece 19 is easily replaced with the dovetail groove portion 67.

  The blindfold piece 19 may be configured to have a different color depending on the target to be attached. For example, it can be a woodgrain. Thereby, the blindfold piece 19 can correspond to various designs by the combination of the door 15 and the sleeve panel 17 and the color development. It can also be less noticeable.

  The recess 55 is provided in the door stop edge 25. The tip of the blind piece 19 enters this concave portion 55. More specifically, in the blindfold piece 19, the bent portion 73 at the tip is arranged in the concave portion 55. The blind piece 19 protruding from the door edge 27 can block the range of the line of sight 69 looking into the room 33 through the gap 29 by arranging the bent portion 73 at the tip in the recess 55.

FIG. 6 is a plan sectional view showing the opening direction of the door 15 when the door is normally opened.
More precisely, the concave portion 55 is a step formed on both sides in the door thickness direction with the raised portion 53 interposed therebetween. That is, the step portion has a flat surface on the opposite side of the raised portion 53 parallel to the door thickness direction. Thus, the door edge 27 has a shape that does not interfere with the blindfold piece 19 when the door 15 is opened toward the indoor side (the direction of arrow A in FIG. 6).

  When the door 15 is forcibly opened in the reverse direction, that is, when the door 15 is emergency opened, the fin portion 65 comes into contact with the raised portion 53 of the door stop edge 25 and bends and deforms without hindering movement in the opening direction. . Also, when the door 15 is returned to its original state from the time of emergency opening, the fin portion 65 comes into contact with the raised portion 53 and is deformed in the opposite direction, and is restored to the original position.

Next, the operation at the time of emergency release will be described.
The door stop member 35 is provided at an upper end of the door 15. The door stop member 35 does not interfere with the sleeve panel 17 by the operation described with reference to FIGS. Thereby, the door 15 can be opened outward (arrow C in FIG. 4).

  When the door 15 is opened outward, the fin portion 65 of the blindfold piece 19 hits the raised portion 53 of the door stop edge 25. When the door 15 is further opened, the fin portion 65 is pressed by the raised portion 53 and deforms so as to fall down to the indoor side. After the door 15 is opened outward, the blindfold piece 19 returns to its original position by elasticity.

  Also, when the emergency-open door 15 is returned, the fin portion 65 hits the raised portion 53 of the door stop edge 25 from outside. The fin portion 65 is deformed outward and falls down. When the door 15 passes into the room, the fin portion 65 returns to its original position by elasticity and returns to the state before the emergency opening.

  In addition to this, the door gap shielding structure can be used not only in an emergency, but also when it is desired to temporarily open the inner opening door 15 during cleaning.

  In addition, in the case of an emergency, the blindfold piece 19 may be damaged due to the operation at that time, but when the door 15 is returned, the shape of the blindfold piece 19 also returns, and it becomes more reusable. preferable.

Next, the operation of the above configuration will be described.
In the door gap-closing structure according to the first embodiment, the blindfold piece 19 having flexibility is attached to a position on the surface of the door edge 27 that is offset toward the indoor side. The blindfold piece 19 is formed to have a band-shaped fin member protruding toward the door stop edge 25 and extending vertically above and below the door. Accordingly, the door gap shielding structure can be a simple structure in which the blindfold piece 19 having a simple shape is attached to the indoor side of the door edge 27.

  Then, the blindfold 19 narrows and blocks the gap 29 by protruding toward the door stop edge 25. In the door gap shielding structure, when the door is closed, the gap 29 between the door stop edge 25 and the door end edge 27 is blocked by the blind piece 19, so that the private room cannot be seen from the outside through the gap 29.

FIG. 7A is a plan sectional view of the gap shielding structure in which the blind piece 19 contacts the door stop edge 25 at the time of emergency opening, and FIG. 7B is a plan sectional view of the gap shielding structure in which the blind piece 19 is deformed at the time of emergency opening. .
Further, the blindfold 19 has flexibility. Even when the door 15 is opened to the outside at the time of emergency opening, the blindfold piece 19 can be easily deformed by receiving a reaction force from the door stop edge 25. Thereby, the blindfold piece 19 can suppress the resistance at the time of interference with the door stop edge 25, and can realize a smooth door opening at the time of emergency opening.

  Further, in the door gap shielding structure, the blind piece 19 is attached to the indoor side of the door edge 27. The door 15 is normally opened to the inside of the private room 21. For this reason, the blind piece 19 is located at a position extending toward the wall panel 13 side, and is difficult to be visually recognized from the entrance 23 side. As a result, in the door gap shielding structure, extra members and structural parts are not normally visible, and the door 15 and the entrance 23 have a neat appearance.

  In the conventional door gap shielding structure, there is a blind piece on the sleeve panel side (door stop edge side), so that it is always noticeable and has a poor appearance. In addition, it is a position that is exposed on the edge of the entrance and always touches when entering and exiting.

  The door gap shielding structure according to the first embodiment has a position where the blind piece 19 extends toward the wall panel 13 when the door is opened, and the door 23 does not have the blind piece 19 at the time of entrance and exit. Not visible from. For this reason, it becomes difficult to be cut by mischief, for example, a blade.

  In the toilet booth 11 as in the first embodiment, when the door 15 is opened inward, and when a person falls down in the room 33, it is necessary to open the door 15 to the outside at the time of emergency opening. However, when the doors are normally closed, the door edge 27 and the door stop edge 25 interfere with each other when the door is opened outside, and the door cannot be opened outside. Therefore, in the door gap shielding structure, the shape of the door stop edge 25 is changed, and the door edge 27 is provided with a flexible fin-shaped blindfold piece 19. Thus, the door 15 can be opened without any trouble at the time of the normal opening and the emergency opening.

  In the market, a door stop member 35 (also referred to as door stop hardware) for emergency solution is prepared. By using the door stop member 35, the door stop function can be easily released at the time of emergency opening.

  In the first embodiment, the gap shielding structure of the door is provided between the door edge 27 and the door stop edge 25. Although not shown, the door gap shielding structure may be provided between the door edge 51 and the door edge 57. In this case, the members to be used can be shared, and the types of parts can be reduced. In addition, the door gap shielding structure has the door bottom edge 51 and the door bottom facing edge 57 set in the same manner (configuration), so that the door bottom edge 51 and the door bottom facing edge 57 are more open than the conventional structure having the concave curved surface 59. A large opening angle at the time can be secured.

  Further, in this door gap shielding structure, the blind piece 19 is inclined in a direction toward the door 15 to open. The door 15 is opened to the outside at the time of emergency opening. The blindfold 19 is inclined in the direction opposite to the door opening direction at the time of emergency opening, that is, in the indoor side. As a result, the blindfold 19 can be easily deformed in a further inclined direction at the time of emergency opening. As a result, the blindfold 19 can be easily bent at the time of emergency opening.

  In this door gap shielding structure, the blindfold piece 19 has a bent portion 73 at the tip. The blindfold piece 19 having the bent portion 73 has a substantially U shape in plan view. That is, the bent portion 73 at the tip is formed by bending further in the same direction with respect to the inclined blindfold piece 19. Therefore, the bent portion 73 does not hinder easy deformation of the blindfold piece 19 in the inclined direction when the blindfold piece 19 moves to the outdoor side during emergency opening. The blind piece 19 has the increased rigidity due to the formation of the bent portion 73. Thus, the blindfold 19 has flexibility and allows easy deformation, while hardly causing sagging or kinking, making it difficult for the blindfold 19 to lose its shape. As a result, the shape of the blindfold 19 can be maintained for a long time, and light leakage and the like can be suppressed.

And in this door gap shielding structure, the blindfold piece 19 is composed of a relatively hard base 63 and a fin 65 that is softer than the base 63. The blind piece 19 is inserted into a dovetail groove 67 extending in the vertical direction formed in the door edge 27 and a base 63 having substantially the same cross-sectional shape as the dove groove 67 is inserted from the upper end or lower end of the door edge 27. And attached. At this time, the workability of attaching the blindfold piece 19 to the dovetail groove part 67 is improved because the base part 63 is hard. In addition, since the blind base 19 has the hard base 63 held by the dovetail groove 67, the mounting strength to the door edge 27 is greater than when the base 63 is soft. Since the fin portion 65 is soft, the blindfold piece 19 to which the base 63 is securely fixed can be easily deformed by the reaction force from the door stop edge 25 at the time of emergency opening. As a result, the blindfold piece 19 can be securely held on the door edge 27, and hindrance at the time of emergency opening can be suppressed.
Although not shown, a dovetail groove may be provided at the base of the blindfold piece 19, and a protrusion or a ridge may be provided at the door edge 27. As described above, the mounting workability is improved by making the base of the blindfold piece hard. improves.

  Further, in the door gap shielding structure, the blind piece 19 can be formed to have a longer protruding length than the case where there is no recessed portion 55 by the amount of entering the recessed portion 55 of the door stop edge 25. The blind piece 19 having a long protruding length has a smaller local deformation amount at the time of emergency opening than the blind piece 19 having a short protruding length. Thus, the blind piece 19 can be deformed with an allowance for the elastic limit at the time of emergency opening. That is, the blind piece 19 can reduce the load at the time of deformation, and can hardly cause plastic deformation. As a result, the blindfold 19 can be made more difficult to bend and can be easily bent.

[Embodiment 2]
Next, a door gap shielding structure according to Embodiment 2 of the present invention will be described.

FIG. 8 is a main part plan sectional view of the toilet booth 11 with the entrance 23 closed by the door 15 in the second embodiment. In the second embodiment, the same members as those described in the first embodiment are denoted by the same reference numerals, and overlapping description will be omitted.
The gap shielding structure of the door according to the second embodiment is different from the configuration of the first embodiment in a blind piece 75, a door stop edge 77, and a door edge 79. Other configurations of the second embodiment are the same as those of the first embodiment.

  In the door gap-closing structure according to the second embodiment, the blinds 75 protrude substantially parallel to the inner surface of the door 15. Further, the door stop edge 77 has a convex curved surface 49 having a vertex substantially at the center of the sleeve panel 17 in the thickness direction T at least on the indoor 33 side.

  Further, in this door gap shielding structure, the curvature circle Cur forming the convex curved surface 49 has a diameter D larger than the plate thickness T of the sleeve panel 17 and smaller than twice the plate thickness T of the sleeve panel 17.

  The front end surface of the door edge 79 is a flat front surface 81. The door tip flat surface 81 is substantially flat. In the second embodiment, the flat top surface 81 is formed with a very gentle curve. Therefore, the door edge 79 is not rectangular in plan view. Note that the door flat surface 81 may be a flat surface orthogonal to the surface of the door 15.

FIG. 9 is a main part plan sectional view showing the opening direction of the door 15 at the time of normal opening in the second embodiment.
The door stop edge 77 has a convex curved surface 49 closer to the room 33 than the vertex. Thus, the door edge 79 has a shape that does not interfere with the blind piece 75 when the door 15 is opened toward the room 33 (in the direction of arrow A in FIG. 9). In the second embodiment, the door stop edge 77 is formed by a convex curved surface 49 (an arc of a curvature circle Cur) in which both the indoor 33 side and the outdoor 47 side are continuous.

FIG. 10A is a plan cross-sectional view of a main part of the gap shielding structure in which the blind piece 75 is in contact with the door stop edge 77 in the emergency opening according to the second embodiment, and FIG. 10B is a gap in which the blind piece 75 is deformed at the time of emergency opening. It is a principal section sectional view of a shielding structure.
When the door 15 shown in FIG. 10A is forcibly opened in the opposite direction (the direction of the arrow C in FIG. 10), that is, when the door 15 is emergency opened, the fin portion 65 causes the fin portion 65 to have the convex curved surface 49 of the door stop edge 77. , And as shown in FIG. 10B, bends without hindering movement in the opening direction. In addition, when the door 15 is returned to its original state from the time of emergency opening, the fin portion 65 comes into contact with the convex curved surface 49 and is deformed in the opposite direction, and is restored to the original position.

  Next, the operation of the above configuration will be described.

  In the door gap shielding structure according to the second embodiment, the blind piece 75 projects substantially parallel to the inner surface of the door 15. That is, the blindfold pieces 75 project almost straight from the door edge 79 toward the door stop edge 77. On the other hand, the door stop edge 77 has a convex curved surface 49 having a vertex substantially at the center in the door thickness direction at least on the indoor 33 side. That is, the door stop edge 77 is a curved surface from which the corner is removed at least on the indoor 33 side from the vertex of the convex curved surface 49.

  Here, the curved surface refers to a so-called R surface having a rounded ridge. In this curved surface, the outside 47 side from the vertex and the indoor side from the vertex become the hem side of the convex curved surface 49 and are hidden (see-through: a part hidden from the surface). In other words, the curved surface from the gap 29 to the back side, that is, from the outdoor to the indoor side or from the indoor to the outdoor side, cannot be seen. The blindfold piece 75 has its tip positioned so as to be closer to the convex curved surface 49 on the indoor side from the vertex, that is, the corner is removed, and protrudes so as to block the line of sight 69, that is, crosses the gap 29. To protrude. As a result, the gap 29 is blocked by the blind pieces 75, so that the inside of the private room 21 cannot be seen from the outside (the outside 47) through the gap 29.

  In this door gap shielding structure, since the door stop edge 77 has the convex curved surface 49, the convex curved surface 49 can be hidden, so that the cover of the blindfold piece 75 can be easily secured with a simple structure. In addition, the blind piece 75 can be formed in a simple linear shape with the projecting direction being substantially parallel to the inner surface of the door 15, and has a neat appearance. As a result, the gap shielding structure can be simplified, and the blind piece 75 can be hardly caught by the door stop edge 77.

FIG. 11A is a plan view of a main part of the gap shielding structure according to the second embodiment in which a normal gap 29 is opened, and FIG. 11B is a plan view of a main part in a state where the gap 29 in FIG. FIG.
In addition, in the door gap shielding structure according to the second embodiment, the standard gap shown in FIG. 11A is caused by the erection of the door 15 (construction tolerance), the dimensional tolerance of each member, and the aging of the member. There is a case where the gap 29 of the distance S becomes the minimum gap distance Smin shown in FIG. When the gap 29 is reduced, it is conceivable that the projecting tip of the blind piece 75 approaches or comes into contact with the door stop edge 77. In this case, the curved surface that is the convex curved surface 49 is a surface in a direction that is steeply separated from the tip of the blindfold piece 75 that moves in the opening direction together with the door 15 when the door 15 is normally opened to the room 33 side. Become. That is, the convex curved surface 49 has an acute angle θ1 between the tangent line 87 at the point where the tip of the blindfold piece 75 contacts and the extension line 89 in the projecting direction of the blindfold piece 75, and the angle of the convex curved face 49 is The convex curved surface 49 becomes smaller toward the skirt side, that is, separates from the tangent line 87 which is a straight line.

  Thereby, in the gap shielding structure of the door, even if the gap distance S of the gap 29 becomes narrower than a preferable interval, and the tip of the blindfold piece 75 may come into contact with the door stop edge 77, the door 15 is normally closed. At the time of opening, the arrangement is such that the door stop edge 77 is easily separated from the surface (convex curved surface 49) of the door stop edge 77, the blindfold piece 75 is caught by the door stop edge 77, and does not hinder the normal opening of the door 15. Further, as compared with the case where the door stop edge 77 is a flat surface, it is possible to reliably prevent the blind piece 75 from contacting the door stop edge 77 to be in a stretched state or to be caught, thereby preventing the door 15 from being normally opened.

  Further, in the door gap shielding structure according to Embodiment 2, the diameter D of the curvature circle Cur forming the convex curved surface 49 is larger than the plate thickness T of the sleeve panel 17. This prevents the convex curved surface 49 from being chipped because the diameter D of the curvature circle Cur forming the convex curved surface 49 becomes smaller than the plate thickness T of the sleeve panel 17. The curvature circle Cur has a diameter D smaller than twice the thickness T of the sleeve panel 17. Thereby, the flattening of the convex curved surface 49 is suppressed, and disappearance of blindness is prevented. As a result, it is possible to ensure the gaze shielding effect. The shape of the convex curved surface 49 is not limited to the above-described curvature circle Cur, but may be any convex curved surface having the vertex substantially at the center of the sleeve panel 17 in the thickness direction. Alternatively, it may be formed in another shape such as a shape formed of a quadratic curve.

FIG. 12 is a main part plan sectional view showing a modification of the second embodiment in which the outdoor 47 side of the door stop edge 83 has a door-tip-facing flat surface 85.
In the door stop edge 83, the convex curved surface 49 may be formed only on the indoor 33 side. In this case, the door stop edge 83 is left with a corner on the outdoor 47 side, and a flat surface 85 facing the door end is formed. When the corner is left, the gap 29 on the outdoor 47 side is narrowed, but the line of sight 69 is blocked as described above. As a result, also in the present modification, the line-of-sight shielding effect does not decrease.

  Therefore, according to the door gap shielding structure according to each of the above-described embodiments, the gap 29 can be blinded with a simple shape, and can pass through the door 15 smoothly at the time of emergency opening, and the appearance is reduced. I will not let you.

  The present invention is not limited to the above-described embodiments, and may be modified or applied by those skilled in the art based on the combination of the components of the embodiments with each other, the description in the specification, and well-known techniques. The present invention is also intended to be included in the scope for which protection is sought.

  For example, in the above configuration example, the case where the door gap shielding structure is applied to the toilet booth has been described as an example, but in addition, the door gap shielding structure requires blindfolding of the gap, and the space for the door is relatively small. The present invention can also be applied to a structure that does not require airtightness, such as a bathroom, a sanitary room, a dressing room, and the like, which needs to be blinded in a gap around a door. In addition, including the case where the present invention is applied to such a structure, the sleeve panel 17 and the wall panel 13 are described as specific examples of the structure in which the door 15 is supported in the above configuration example. The door 15 may be supported directly on the skeleton side of the structure or via the sleeve panel 17.
