Abstract

PROBLEM TO BE SOLVED: To provide a folding door with a simple structure, which is capable of effectively preventing a finger of an operator from being squeezed in a space between butt ends when closing the folding door or a swing door, reducing an impact to the squeezed finger, if any, easily adding a finger squeezing prevention function to an existing folding door, and absorbing the impact resulting from collision between the butt ends of a door panel.SOLUTION: A folding door is provided with a plurality of door panels foldably linked with one another with hinges. The door panel has a soft deformable elastic sheet applied onto the butt end and a portion between the butt ends. A thickness of the soft elastic sheet at least at the portion between the butt ends is larger than half the distance of a gap between the butt ends in a closed state. The soft elastic sheet is structured to be deformed to move from a hinge side to a free end side in a width direction of the respective butt ends which approach when closing the folding door. The soft elastic sheet is further structured to self restore the deformation from the free end side to the hinge side when opening the respective butt ends.

Description

  The present invention relates to a folding door in which a plurality of door plates are foldably connected and a hinged door including a door plate and a support member that are connected to each other by a hinge.

  The folding door is generally configured by connecting door plates with hinges, and when closing the doors, the side end surfaces (cut end surfaces) of the connected door plates are also closed. For this reason, when a folding door closes, a finger may be pinched between side end surfaces. Similarly, when the hinged door is closed, a finger may be sandwiched between the end surface of the support member and the side end surface of the door plate. The following known documents exist as such a structure for preventing the pinching of folding doors and hinged doors.

  In Patent Document 1, a flexible sheet for preventing pinching of fingers, which is made of a reinforced paper such as synthetic resin impregnated paper or synthetic resin coated paper or a synthetic resin sheet, is disposed and fixed on the side surface of the door adjacent to the folding door. It is disclosed. This bendable sheet has an intermediate bent portion protruding at an intermediate portion of an adjacent door, and the intermediate bent portion tries to prevent a finger from being caught between the side surfaces of the door when the folding door is closed. Is.

  Patent Document 2 discloses that a hollow deformable body is fixed to a side end face of a folding door panel adjacent to the folding door. When a finger is sandwiched between the side end surfaces of the folding door panel, the hollow deformable body is deformed in accordance with the finger, thereby preventing the sandwiched finger from being strongly pressed and injured.

  Patent Document 3 discloses that a main surface (opposing surface) to which a hinge of an adjacent door panel of a door structure is attached is provided with a lip member provided with a protruding portion to shield a gap and one of the opposing surfaces of the lip member. It is disclosed that the portion is an inclined surface. With such a structure, the finger is prevented from entering the gap, and the finger is pushed out by the inclined surface to prevent the finger from being pinched between the door panels.

  Patent Document 4 discloses a structure in which a bar-shaped member interposed along the vertical direction is provided at the connecting portion of the folding door, and the rod-shaped member is moved away from the folding fulcrum of the folding door when the folding door is closed. In this structure, when the folding door is closed, the finger is pushed out from the gap of the connecting portion to prevent the finger from being stuck.

  However, according to the structure disclosed in Patent Document 1, since the flexible sheet for preventing pinching is made of thin paper or resin, the intermediate bent portion is also thin and soft, and the finger is pinched by this portion. Cannot be prevented. Moreover, because of the thin bendable sheet, it is impossible to absorb the impact when a finger is pinched. In addition, when the hinge is provided in a digging manner with respect to the door plate and the gap between the adjacent side surfaces of the door plate is small, the side surfaces may collide when the folding door is closed vigorously. At this time, since the flexible sheet is thin, the impact of the collision cannot be absorbed, and there is a possibility that a loud collision sound is generated or the door is damaged.

  According to the structure disclosed in Patent Document 2, it is impossible to prevent the finger itself from being sandwiched between the side end surfaces. Further, in order to provide the hollow deformable body, it is necessary to sharpen the side end face, and therefore this hollow deformable body cannot be easily provided to the existing folding door.

  According to the structure disclosed in Patent Document 3, even if an inclined surface is provided on the side end surface member, it is difficult to reliably push out the finger to the outside by the inclined surface, and the side end surface member is formed of a hard material. Therefore, finger pinching occurs.

  According to the structure disclosed in Patent Document 4, when a folding door is closed, a finger may be pinched between a hard rod-like member and a connecting portion of the folding door, and finger pinching cannot be completely prevented. A mechanism for moving the rod-shaped member must be provided, the structure becomes complicated and the manufacturing cost increases, and failure is likely to occur. In addition, it is difficult to provide an existing folding door because it takes time. Furthermore, when the folding door is closed, there is a risk of failure due to an impact applied to the surface of the connecting portion.

  In view of the above-described problems, the inventors of the present application have been diligently researching to develop a technique for reliably preventing a finger from being caught between the side end surfaces of the connected door plates. If a soft member such as the intermediate bent portion of Patent Document 1 or the hollow deformed body of Patent Document 2 is used instead of the material of the side end face member of Patent Document 3, when the finger is sandwiched, Such an impact is alleviated and the finger is easily pulled out. However, the action of the inclined surface pushing the finger outward is weakened, and as a result, the finger cannot be effectively prevented from being pinched.

  When the soft member employed in Patent Document 1 or Patent Document 2 is used instead of the material of the bar-shaped member of Patent Document 4, the action of the bar-shaped member pushing the finger out of the connecting portion of the folding door is weakened. . Furthermore, it is impossible to prevent a finger from being sandwiched between the connecting portion of the folding door and the rod-shaped member.

  The inventors of the present application have considered that these problems occur because the soft member cannot effectively combine the action of pushing out the finger. Therefore, further research was conducted in order to develop a technique that can reliably push out a finger from the side end face (the end face) using a soft member.

  The present invention has been developed based on the above-described background, and its purpose is to effectively put a finger in the gap between the front ends or between the end surfaces of the support member and the front end when closing the folding door or the hinged door. An object of the present invention is to provide a folding door and a hinged door having a finger pinching prevention function that can reduce the impact on a finger even when pinched.

  Another object of the present invention is a folding door and a hinged door that have a simple structure, can easily add a finger pinching prevention function to existing folding doors and hinged doors, and also have an effect of absorbing the impact of collision between the wooden surfaces of the door plates. Is to provide.

  The folding door of the present invention is a folding door comprising a plurality of door plates that are foldably connected by a hinge, and this door plate is covered with a soft elastic sheet that can be deformed in a portion extending between the end face and each end face, The soft elastic sheet has a thickness that is at least a part of the gap between the front ends when the front end is closed, and the soft elastic sheet approaches when the folding door is closed. Each of the mouth ends is deformed so as to move from the hinge side in the width direction to the free end side, and the deformation is automatically restored from the free end side to the hinge side when each mouth end surface is opened.

  When the doorboard is folded and the folding door is closed, the soft elastic sheet on both the front ends of the doorboard is sandwiched between the front ends of the doorboard, and the soft elastic sheets themselves are also folded and overlapped. In other words, as the folding door closes, the adjacent cuff surfaces approach and close together, but at that time, the soft elastic sheet on the cuff surface is sequentially folded from the hinge-side edge toward the free-end side edge. It overlaps and goes between the mouths. At this time, the soft elastic sheet can be deformed, and the thickness of the overlapped soft elastic sheets is larger than the gap distance between the mouth ends in the portion spanning the end of the mouth. The part that does not fit within the gap distance between the mouth surfaces generated by the above becomes the surplus part, and the surplus part moves from the edge on the hinge side toward the edge on the free end side as the gap between the mouth faces closes Deform. When a finger is inserted between the end surfaces, the deformation of the soft elastic sheet causes the fingers to be pushed out in the direction of deformation, and thus completely from between the end surfaces. Furthermore, this soft elastic sheet absorbs the impact of the force applied to the finger before being pushed out. By these actions, it is possible to prevent the fingers from being pinched into the folding door. When the folding door is opened, the gap between the ends is opened and the pressure applied to the soft elastic sheet is removed, so that the deformation is restored from the edge on the free end side to the edge on the hinge side. That is, when the folding door is opened, the soft elastic sheet returns to its original shape again.

  Since the soft elastic sheet is provided between the front ends of the door plate, the finger between the front ends can be pushed out regardless of the portion where the front end is inserted. Therefore, a finger does not enter the gap between the door plates, and the finger can be prevented from being caught in the gap. The soft elastic sheet protects the wooden face of the door plate and absorbs the impact applied to the wooden face when the folding door is suddenly closed. Further, since only a single soft elastic sheet needs to be attached, the gap between the door plates and the hinges are concealed, so that the aesthetic appearance is not impaired and the installation is easy. Furthermore, since it is only necessary to adhere a soft elastic sheet, it can be installed on an existing folding door, and the manufacturing cost and installation cost can be reduced.

  The soft elastic sheet is preferably a gel sheet. When it is in a gel form, it is very easily deformed when the folding door is closed, and it is easy to push out the finger and absorb the shock. Moreover, when a folding door is opened, it can return to the original shape, and when a force is not applied, it maintains a certain shape. If it is a sheet | seat, the same structure can be easily installed with respect to elongate like a mouth end surface, and removal is also easy.

  It is also preferable that the soft elastic sheet has a uniform thickness. Since the entire thickness of the soft elastic sheet is larger than the gap at the end, the volume is the largest, and the action of pushing out the finger when closing the folding door is strong, and the impact applied to the finger and door plate is effective. Can be absorbed. The uniform thickness makes it particularly easy to manufacture and install.

  It is also preferable that the soft elastic sheet has a convex thick portion in a portion extending between the end surfaces or a convex shape having a portion having the largest thickness in a portion extending between the end surfaces. The action of pushing out the finger is strongest at the portion provided between the end surfaces, and the finger is prevented from being pinched deeply. Since the soft elastic sheet is thinned away from the part provided between the end surfaces, the thick part or the thickest part is easily deformed in the direction away from the soft elastic sheet, and the finger is particularly easily pushed out.

  According to the present invention, the hinged door includes a door plate and a support member that are connected to each other by a hinge, and can be deformed into a door end of the door plate, an end face of the support member, and a portion extending between the end face and the end face. A soft elastic sheet is attached, and the soft elastic sheet has a thickness greater than half the gap distance between the end face and the end face when at least a portion between the end face and the end face is closed. The seat is deformed so that it moves from the hinge side in the width direction between the front and end surfaces approaching when the hinged door is closed to the free end side, and the deformation is restored from the free end side to the hinge side when the hinged door is opened. A hinged door is provided.

  When closing the hinged door, the soft elastic sheet on the end face and the end face is sandwiched between the end face and the end face, and the soft elastic sheet itself is folded and overlapped. That is, as the hinged door is closed, the adjacent end face and the end face are brought close to each other. At that time, the soft elastic sheet on the end face and the end face is moved from the hinge side edge to the free end side edge. Folds one after another and is sandwiched between the end face and the end face. At this time, the soft elastic sheet can be deformed, and the thickness of the overlapped soft elastic sheet is larger than the gap distance between the end face and the end face in the portion extending over the end face and the end face. The part that does not fit in the gap distance between the end face and the end face caused by the difference from the distance becomes the surplus part, and as the end face and the end face close, the direction from the hinge side edge to the free end side edge The navel surplus part is deformed to move. When a finger is inserted between the end face and the end face, the deformation of the soft elastic sheet causes the finger to be pushed out in the direction of the deformation, and thus completely pushed out from between the end face and the end face. Furthermore, this soft elastic sheet absorbs the impact of the force applied to the finger before being pushed out. With these actions, it is possible to prevent pinching of the hinged door. When opening the hinged door, the gap between the end face and the end face is opened, and the pressure applied to the soft elastic sheet is removed, so that the deformation is restored from the edge on the free end side to the edge on the hinge side. That is, when the hinged door is opened, the soft elastic sheet returns to its original shape again.

  The soft elastic sheet is preferably a gel sheet. When it is in a gel form, it is very easy to deform when the hinged door is closed, and it is easy to push out the finger and absorb the shock. In addition, when the hinged door is opened, it can return to its original shape, and when a force is not applied, a certain shape is maintained. If it is a sheet | seat, the same structure can be easily installed with respect to elongate like an end surface and a front end, and removal is also easy.

  It is also preferable that the soft elastic sheet has a uniform thickness. Since the entire surface of the soft elastic sheet has a thickness larger than the gap between the end face and the end face, the volume is the largest, and the action of pushing out the finger when the hinged door is closed is strong, and the impact applied to the finger and door plate Can be absorbed effectively. The uniform thickness makes it particularly easy to manufacture and install.

  It is also preferable that the soft elastic sheet has a convex thick portion in a portion extending between the end surface and the end surface, or a convex shape having a portion having the largest thickness in a portion extending between the end surface and the end surface. . The action of pushing out the finger is strongest at the portion provided between the end face and the end face, and the finger is prevented from being pinched deeply. Since the soft elastic sheet is thinned away from the part provided between the end face and the end face, the thick part or the thickest part is easily deformed in the direction away from the soft elastic sheet, and the finger is particularly easily pushed out.

  According to the present invention, when the door plate is folded and the folding door is closed, the soft elastic sheets on both the front ends of the door plates are sandwiched between the front ends of the door plates, and the soft elastic sheets themselves are also folded and overlapped. In other words, as the folding door closes, the adjacent cuff surfaces approach and close together, but at that time, the soft elastic sheet on the cuff surface is sequentially folded from the hinge-side edge toward the free-end side edge. It overlaps and goes between the mouths. At this time, the soft elastic sheet can be deformed, and the thickness of the overlapped soft elastic sheets is larger than the gap distance between the mouth ends in the portion spanning the end of the mouth. The part that does not fit within the gap distance between the mouth surfaces generated by the above becomes the surplus part, and the surplus part moves from the edge on the hinge side toward the edge on the free end side as the gap between the mouth faces closes Deform. When a finger is inserted between the end surfaces, the deformation of the soft elastic sheet causes the fingers to be pushed out in the direction of deformation, and thus completely from between the end surfaces. Furthermore, this soft elastic sheet absorbs the impact of the force applied to the finger before being pushed out. By these actions, it is possible to prevent the fingers from being pinched into the folding door. When the folding door is opened, the gap between the ends is opened and the pressure applied to the soft elastic sheet is removed, so that the deformation is restored from the edge on the free end side to the edge on the hinge side. That is, when the folding door is opened, the soft elastic sheet returns to its original shape again.

  Since the soft elastic sheet is provided between the front ends of the door plate, the finger between the front ends can be pushed out regardless of the portion where the front end is inserted. Therefore, a finger does not enter the gap between the door plates, and the finger can be prevented from being caught in the gap. The soft elastic sheet protects the wooden face of the door plate and absorbs the impact applied to the wooden face when the folding door is suddenly closed. Further, since only a single soft elastic sheet needs to be attached, the gap between the door plates and the hinges are concealed, so that the aesthetic appearance is not impaired and the installation is easy. Furthermore, since it is only necessary to adhere a soft elastic sheet, it can be installed on an existing folding door, and the manufacturing cost and installation cost can be reduced.

  Since the soft elastic sheet is provided between the end face and the end face, it is possible to push out the finger between the end face and the end face regardless of the place where the finger enters. Therefore, a finger does not enter the gap between the end face and the end face, and the finger can be prevented from being caught in the gap. The end face and the end face are protected by the soft elastic sheet, and the impact applied to the end face and the end face when the hinged door is suddenly closed is absorbed. Further, since only a single soft elastic sheet needs to be attached, the gaps and hinges of the hinged door are concealed, so that the aesthetic appearance is not impaired and the installation is easy. Furthermore, since it is only necessary to adhere a soft elastic sheet, it can be installed on an existing hinged door, and the manufacturing cost and installation cost can be reduced.

  The folding door 1 of the present embodiment includes a plurality of door plates 10A and 10B, which are foldably connected by a plurality (two in the figure) hinges 20. In the present embodiment, the door plates 10A and 10B are folding doors whose upper end portions and lower end portions are movably supported via rails R1 and R2 laid above and below them via runners (not shown). A folding door handle 40 is provided near an end of the door plate 10B that is connected to the door plate 10A at a middle height in the vertical direction. By pulling the folding door handle 40 toward the front, the door plates 10A and 10B are hinged. The folding door 1 is configured to be folded in the direction of 20 and closed.

  The hinge 20 has a function of connecting the door plates 10A and 10B so as to be rotatable in the horizontal direction with this portion as a rotation axis. In this embodiment, the hinge 20 is a two-blade type made of a metal material or a resin material. It is composed of a general hinge (without back pushing type). The hinge 20 includes a shaft portion 23 and a blade portion 21, and the blade portion 21 is fixed to the door surfaces of the door plates 10 </ b> A and 10 </ b> B with wood screws 22.

The side end surfaces of the door plates 10A and 10B connected by the hinge 20 are end surfaces that face each other when the folding door is closed. Hereinafter, these end surfaces are referred to as the end surfaces 11A and 11B. These edges of the adjacent butt end surfaces 11A and 11B hinge 20 side of the the edges 11A ₁ and 11B _1, the opposite side of the edge to the edge 11A ₁ and 11B ₁ of the cut end surface 11A and 11B, i.e. butt the free end of the edge surface, referred to as edge 11A ₂ and 11B ₂ a.

  A soft elastic sheet 30 is attached over the wood surfaces 11A and 11B of the door plates 10A and 10B. More specifically, the attachment members 37A and 37B are fixed to the facets 11A and 11B, and one continuous soft elastic sheet 30 is fixed to the attachment members 37A and 37B. The soft elastic sheet 30 is a freely deformable sheet. Here, “elasticity” is a property that deforms when pressure is applied from the outside and returns to its original shape when pressure is removed. “Soft elasticity” is a particularly soft material that has elasticity and is almost free. It can be deformed in shape and size. Materials with such properties include soft and elastic shapes such as sponges made of highly elastic and soft gels, soft rubber, other elastomeric compounds, or those materials and soft synthetic resins. and so on. Examples of the gel include styrene elastomers, urethane elastomers, silicon elastomers, and olefin elastomers. The thickness of the gel can be selected from 0.5 to 10 mm, preferably 1.0 to 3.0 mm. As the soft elastic sheet 30 of the present embodiment, a gel sheet made of styrene-based elastomer and having a thickness of 1.0 mm is used. As the physical properties of the gel, a gel having a tensile strength measured by JIS K 6251 of 2.4, a 100% tensile stress of 0.1 MPa, and a breaking elongation of 1600% was used this time, but is not limited to these values.

  As shown in FIGS. 1 and 2, the soft elastic sheet 30 is arranged in the horizontal direction so as to cover the gap 12 between the door plates 10 </ b> A and 10 </ b> B generated when the folding door 1 is opened. It is continuously applied on 11A and 11B and between the end surfaces. The soft elastic sheet 30 is preferably applied over the entire top and bottom surfaces of the end surfaces 11A and 11B, but may be applied only to the vertical region necessary for preventing finger pinching.

  In the present embodiment, as shown in FIG. 2, the portion of the soft elastic sheet 30 that spans between the wooden facets 11 </ b> A and 11 </ b> B of the doorboard is defined as a gap area 31, and the part that is deposited on the wooden face is the wooden face area 32. And 33, the total thickness d of the soft elastic sheet 30 and the mounting member 37A or 37B at least in the gap region 31 is as shown in FIG. 5 when the folding door 1 is closed, as shown in FIG. And 11B is larger than half of the gap distance D (d> D / 2). This gap distance D is determined by the thickness of the hinge 20 and the mounting structure. In the present embodiment, the soft elastic sheet 30 has a uniform thickness d over the gap region 31 and the entire end surface regions 32 and 33.

  In this embodiment, the end surfaces 32 and 33 of the soft elastic sheet 30 are attached to the attachment members 37A and 37B, respectively. The attachment members 37A and 37B are thin plate-like members that are easily fixed to the facets 11A and 11B, and are made of resin or the like, for example, hard rubber or elastomer. In the present embodiment, a hard elastomer is used as a constituent material. The attachment members 37A and 37B are fixed to the facets 11A and 11B. In the present embodiment, the primer is applied to the attachment members 37A and 37B, and then a double-sided tape is applied to adhere to the small edge surfaces 11A and 11B.

  Next, the operation | movement and effect of the folding door 1 of this embodiment are demonstrated using FIGS.

In the state in which the folding door 1 is opened, as shown in FIG. 2, the end surfaces 11A and 11B are substantially parallel to each other. When the folding door 1 starts to close, the end surfaces 11A and 11B begin to approach each other from a substantially parallel state as shown by an arrow C in FIG. At that time, the end surfaces 32 and 33 of the soft elastic sheet 30 are sandwiched and folded between the end surfaces 11A and 11B. When Orito 1 go further closed, soft elastic sheet 30, as shown in FIG. 3, under pressure sandwiched between butt end surfaces 11A and 11B, the surplus portion 35 edges 11A ₁ and is a part It is deformed so as to move in the direction of the edges 11A ₂ and 11B ₂ from the 11B ₁ side. Thus, the surplus portion 35, as Orito 1 is closed, go pushed in the direction r of the edge 11A ₂ and 11B ₂ on the side of the free end.

  At this time, as shown in FIGS. 3 and 4, if the finger T is inserted between the end surfaces 11 </ b> A and 11 </ b> B, the finger T is pushed by the surplus portion 35 of the soft elastic sheet 30 and the same direction as the direction r. Extruded to R. In this embodiment, as the end surfaces 11A and 11B close, more portions of the soft elastic sheet 30 receive pressure, so the surplus portion 35 increases, and the finger T is pushed out in the direction R with greater force. As shown in FIG. 5, when the folding door 1 is further closed and the end surfaces 11A and 11B face each other, the finger T is completely pushed out from between the end surfaces, so that the fingers are sandwiched between the door plates 10A and 10B. Is reliably prevented.

  In particular, in the present embodiment, the gap region 31 of the soft elastic sheet 30 has a thickness d larger than half of the gap distance D between the end surfaces 11A and 11B when the folding door 1 shown in FIG. 5 is completely closed. In addition, the total thickness d × 2 of the end surfaces 32 and 33 of the folded soft elastic sheet 30 is larger than the gap distance D between the end surfaces. That is, as shown in FIG. 3, the surplus portion 35 becomes a part of the soft elastic sheet 30 that is caused by the difference between the thickness d × 2 and the gap distance D and does not fit within the gap distance D between the end surfaces. ing.

  Thus, in this embodiment, since the flexible elastic sheet 30 has a uniform thickness d, as shown in FIG. 3, it is caused by the difference between the thickness d × 2 and the gap distance D as the mouth end surface is closed. The surplus part 35 will continue to increase.

When opening the folding door 1, contrary to the above description, the end surfaces 11A and 11B go away from each other in the direction O shown in FIG. because 11A and pressure had received from 11B is released, the deformation is self restored from the edge 11A ₂ and 11B ₂ on the side of the free end in the direction of the edges 11A ₁ and 11B ₁ of the hinge 20 side. Therefore, the shape of the soft elastic sheet 30 recovers to the state shown in FIG.

  As shown in FIG. 2, when the folding door 1 is open, the gap 12 between the door plates 10A and 10B is covered with a soft elastic sheet 30 provided between the end surfaces of the door plates 10A and 10B. For this reason, a finger does not enter the gap 12 through the end face of the door plates 10A and 10B. Therefore, even when the folding door 1 is closed, the finger is not fed into the gap 12 by the rotating door plates 10A and 10B.

  Furthermore, according to this embodiment, since the soft elastic sheet 30 is a gel sheet, the pressure applied from the door plates 10A and 10B to the finger T when the folding door 1 is closed is relaxed. Moreover, when the folding door 1 closes abruptly, the impact at the time of collision of the end surfaces 11A and 11B is also alleviated.

  In order to form the folding door 1 of the present embodiment, the soft elastic sheet 30 may be fixed to the door plate when the folding door is newly manufactured, or the soft elastic sheet 30 is attached to the door plate of the existing or already installed folding door. May be fixed. That is, the folding door of this embodiment can be formed only by sticking the soft elastic sheet 30 with the double-sided tape etc. with respect to both the mouthpiece surfaces 11A and 11B of a doorplate. In this embodiment, since the soft elastic sheet 30 is a rectangular long gel sheet having a uniform thickness, it is easy to transport and handle, and in accordance with the vertical length of the couch face of the door plate when fixed. Since it only needs to be cut and fixed, the operation is extremely easy, and the manufacturing can be performed easily and inexpensively.

  In another modification of this embodiment, as shown in FIG. 6, the attachment members 37C and 37D are locked to the end surfaces 11A and 11B by the attachment member locking portions 37E and 37F, respectively. In the example shown in FIG. 6, the attachment member locking portions 37E and 37F have a gasket structure provided along the longitudinal direction substantially at the center in the width direction of the end surfaces 11A and 11B of the attachment members 37C and 37D. Groove-shaped insertion portions 11C and 11D into which the gasket structure can be fitted are formed in the end surfaces 11A and 11B. By fitting the attachment member locking portions 37E and 37F into the insertion portions 11C and 11D, respectively, the attachment members 37C and 37D are fixed to the end surfaces 11A and 11B.

[Second Embodiment]
7 is a horizontal sectional view showing the operation of the main part when the folding door of the second embodiment of the present invention is opened, and FIG. 8 is a horizontal sectional view showing the operation of the main part when the folding door of FIG. 9 is a horizontal sectional view showing the operation of the main part when the folding door of FIG. 8 is further closed, and FIG. 10 is a horizontal sectional view showing the main part when the folding door of FIG. 9 is completely closed. In this embodiment, the soft elastic sheet 30A has a convex thick portion 34 in a gap region 31 that is a portion provided between the end surfaces 11A and 11B. Note that elements having substantially the same configuration and operational effects as those of the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  The thick portion 34 has a thickness d (d> D / 2) larger than a half of the gap distance D between the end surfaces 10A and 11B of the door plates 10A and 10B when the folding door is closed. Thus, it may be formed only in the gap region 31 or may be formed over a wider width. Other portions of the soft elastic sheet 30 </ b> A have a uniform thickness that is thinner than the thick portion 34. Although the cross-sectional shape of the thick portion 34 is arbitrary, it is desirable that the thick portion 34 be formed in a convex shape having the center 36 of the gap region 31 as a vertex. Thereby, the effect | action which deform | transforms and extrudes the soft elastic sheet 30A in the clearance gap area 31 becomes the strongest. In the present embodiment, the thick portion 34 is formed to have a semi-circular cross section only in the gap region 31.

  In the present embodiment, the thick portion 34 of the soft elastic sheet 30A has a thickness of 2.0 mm, and the other portions of the soft elastic sheet 30A have a uniform thickness of 1.0 mm. The soft elastic sheet 30A is directly attached to the end surfaces 11A and 11B. The means for directly attaching may be surface-treated so that the surface of the soft elastic sheet 30A has adhesiveness, or may be via a double-sided tape or the like.

  The operation and effects of the folding door of this embodiment will be described. As shown in FIG. 8, the finger T is pushed out when the folding door is closed as in the case of the first embodiment. Since the volume of the surplus portion 35A is large near the gap region 31, the force that pushes the finger T in the direction R becomes stronger. Further, since the thickness d ′ of the portion other than the thick portion 34 is thinner than the thickness d of the thick portion 34, the deformation of the soft elastic sheet 30A occurs without resistance, and the surplus portion 35A is other than the thick portion 34. Easy to push in the direction. In particular, in the present embodiment, the thick portion 34 is formed so as to have a semi-circular cross section with the center 36 of the gap region 31 as an apex, so the force pushed out at the center 36 is the strongest, and the finger T is hinged. Easy to push from the side. Therefore, as shown in FIG. 8, when the finger T is deeply inserted between the front ends, the finger T is particularly strongly pushed out, and thus it is possible to effectively prevent the finger T from being pinched deeply.

  In the present embodiment, in the state of being further closed as shown in FIG. 9, the portions other than the thin thick portion 34 having the thickness d ′ are not deformed, and thus the operation of closing without applying force to the soft elastic sheet 30 </ b> A is continued. be able to. Since the deformation of the soft elastic sheet 30A occurs without resistance, the soft elastic sheet 30A is hardly damaged by repeated deformation and can be used for a long time. Furthermore, in the completely closed state shown in FIG. 10, since the volume of the surplus portion 35 is small, the surplus portion 35 pushed out between the end surfaces 11A and 11B is small. Therefore, the beauty of Orito is not impaired.
