Description

  TECHNICAL FIELD The present invention relates to a finger clogging prevention device attached to a connecting portion of a folding door that is foldably connected, and a folding door to which this is attached.

  When the folding door is opened, the connecting portion connecting two adjacent door plates protrudes forward from the guide rail, while the gap created by abutting the connecting ends of the door plates expands like a fan. When the door plate is opened until it is completely folded, the two door plates overlap each other, and both end faces of the connecting portion face in a direction perpendicular to the guide rail. On the other hand, when the folding door is closed, the space between the connecting end portions of the two door plates in the connecting portion closes like scissors.

  Since the folding door performs such an operation by opening and closing, conventionally, if the folding door in the open state is to be closed while pressing between the connecting end portions of the door plates in the connecting portion with fingers, the connecting end portion of the two door plates There was a risk of fingers being caught between them.

  In addition, the connecting part of the folding door is configured by connecting the door plates with a connecting member such as a hinge, and has a structure that can be folded using the hinge pin of the hinge as a connecting fulcrum. In order to arrange the hinge, A slight gap is formed between the rear corners of the door plate. In particular, until the folding door shifts from the fully open state to the closed state, the connecting end portion of the door plate in the connecting portion is in an open state, so that the supporting shaft portion of the connecting fulcrum, that is, the two door plates The gap formed between the rear corners of the connecting end is exposed forward through the gap between the ends. This gap is about 4 to 5 mm, and there is almost no risk that fingers will be caught in adults, but there is a possibility that fingers will be caught in the gap in infants.

  In order to prevent finger filling in the gap between the connecting end portions of the door plate in the connecting portion and the gap of the support shaft portion, a folding door provided with a finger clogging prevention tool or such a member in the connecting portion is provided. Have been proposed (see, for example, Patent Document 1).

  The finger clogging prevention means described in Patent Document 1 is a soft member such as a membrane interposed between the end portions of the door plate so as to be foldable and unfoldable. When the folding door is closed by this soft member, The gap formed in the support shaft portion is shielded from the front to prevent the finger from entering the gap.

  By the way, in the conventional folding door, there is one in which a pulling operation from the closed state of the folding door can be performed on the front face of the folding door of the connecting portion with a handle formed by a clue recess (for example, Patent Document 2). See). In this kind of thing, there is usually a gap between the connecting end portions that are formed by abutting the end portions of the door plate behind the recess, but in the technique of the same document, the gaps and gaps that can be formed in the connecting portion when the folding door is closed. It is covered with a doorboard structure to prevent finger clogging.

Japanese Utility Model Publication No. 63-23482 JP 2008-240377 A

  However, the main purpose of the gap shielding structure of Patent Document 2 is to improve aesthetics, and the finger clogging prevention function is merely an additional one. That is, according to the folding door of the same document, since the gap is formed at a position shifted rearward of the recess, the gap is hidden when the folding door is closed, but in the opened state of the folding door, the gap and the gap behind the gap are hidden. Will not give the user 100% security.

  In such a folding door with a handle, in order to give an appropriate finger-clogging prevention function, a structure of a shielding film as shown in Patent Document 1 is required as in a folding door without such a handle. Is done. However, since a clue recess is formed in the connecting end portion of the door plate, the facing end face space of the connecting end portion of the door plate is small, and therefore it is almost impossible to interpose a shielding film between the end portions. Is possible.

  In addition, if a shielding film is provided in front of the gap so as to hide the gap at all times, the effect of preventing finger clogging becomes extremely high. However, such a shielding film must be provided in the space of the clue recess. Then, when the folding door is closed, the recess space is blocked by the shielding film, and it is impossible to put a hand into the recess, or even if it can be inserted, the handle and the deformed shielding film Fingers may be pinched. In other words, this type of handle is incompatible with the anti-clogging device that must be provided at the connecting portion in the same way as the handle. Conventionally, no anti-clogging device having an appropriate anti-clogging function has been proposed. It was.

  The present invention has been proposed in view of such circumstances, and its purpose is to allow a finger to enter the gap between the butt end portions of the door plate at the connecting portion in a folding door with a handle that can be pulled. An object of the present invention is to provide a finger clogging prevention device that can be reliably prevented with a simple structure and that does not interfere with the opening / closing operation of the folding door, and a folding door equipped with the same.

  In order to achieve the above object, the finger clogging prevention device according to claim 1 is provided with a shield, and is attached to a connecting portion of a folding door in which a plurality of door plates are connected in a foldable manner. The gap is formed between the connecting end portions of the door plates in the portion and conceals the gap that expands and contracts by opening and closing the folding door, and has the following characteristic structure.

  That is, in this anti-clogging tool, the door plate has a butt end that is abutted across the gap at the end of the folding door, and a recess that is adjacent to the side of the fold door in the projecting direction of the fold door. And a handle that forms an opening that leads to the outside from the recess and protrudes from each other on the front face of the door plate further forward of the recess, and the opening of the folding door causes the butt end, the recess, and the handle to be fan-shaped. The shielding body has a plate-like operating piece that has a bent portion at the center and can be folded and unfolded, and both end portions in the width direction of the operating piece are both It is attached to the butt end of the door plate to hide the gap, and when the folding door is closed, the operating piece is folded along the protruding direction of the folding door at the approximate center of the adjacent recess formed by the two recesses adjacent to each other. On the other hand, when the folding door is opened, the operating piece is deployed. It is arranged in the jar.

  In the second aspect, the operating piece is developed so that the bent portion is bent at an obtuse angle and protrudes forward when the folding door is opened.

  According to a third aspect of the present invention, the finger clogging prevention device further includes a fixture that fixes and supports the shield so that the operation piece can be operated, and the shield has attachment portions extending to both side ends of the operation piece. Provided, and the attachment portion is fixed to the butt end portion of the door plate by a fixture.

  According to a fourth aspect of the present invention, the fixture is constituted by a plate-like body, and extends from the fixed portion to the rear surface of the door plate via a gap between the connecting end portions of the door plate. A connecting support portion having a connecting piece to be connected to the attaching portion, and a structure in which the butted end portion is sandwiched between the connecting support portion and the fixing portion, and the attaching portion of the shield is a connecting piece of the fixing tool. To be connected by being engaged with each other, and the connecting piece and the connected portion of the shield are connected to each other at the back of the recess.

  According to a fifth aspect of the present invention, the connecting piece of the fixture has a bent shape, and the connected portion of the shield has an insertion groove structure in which the connecting piece is fitted by press fitting.

  The folding door according to claim 6 has a connecting portion in which a plurality of door plates are connected so as to be foldable, and when opened, a gap that expands and contracts by opening and closing is formed between the connecting end portions of the door plates in the connecting portion. It is a folding door, Comprising: The finger clogging prevention tool of any one of Claims 1-5 is mounted | worn.

  According to the first and sixth aspects of the present invention, the gap between the butt end portions that expands and contracts as the folding door opens and closes is reliably hidden while the operating piece of the shield is expanded and folded. As a result, there is no possibility that fingers will be sandwiched between the butted ends by the operation of the folding door.

  In the closed state of the folding door, the operating piece of the shield is folded at the central bent portion, and the centers of the adjacent recesses are arranged along the protruding direction. The finger is not peeled off, and the finger can be easily put into the recess for the pulling operation of the handle. Furthermore, in the closed state of the folding door, the folded operating piece is almost accommodated in the recess, so that it may look good.

  According to the finger-clogging prevention device according to claim 2, since the bent portion of the operating piece is deployed in an obtuse angle and protrudes forward when the folding door is closed, the folding door shifts from the state to the closing operation. When doing, it can prevent that an operation piece bends so that it may protrude in the opposite direction (back).

  According to the finger clogging prevention device according to claim 3, since the attachment portion extended from the both side ends of the operation piece is fixed to the butt end portion of the door plate by the fixture, the operation piece operates smoothly.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  First, the structure and shape of the fingernail preventer of the same embodiment and the folding door equipped with the same will be described with reference to FIGS. FIG. 4 (a), which is a plan view of a shield that is a constituent member of the finger clogging prevention device, and FIG. 5, which is a plan view of the finger clogging prevention device, show a state in which the shield is deployed. Yes.

  The folding door 10 is used as a closet door or a partition that can be opened and closed between adjacent rooms. In the illustrated example, two sets of folding doors 10, 10 including a pair of connected door plates 12, 12 are mounted on a guide rail 4 laid on the sill 3 so as to be openable and closable.

  More specifically, the two door plates 12 constituting the folding door 10 are connected so that adjacent connecting end portions 12a are turnable by a hinge 11a, and the other end portion 12b of one door plate 12 is The other end 12b of the other door plate 12 is attached to the rail 4 so as to be able to travel.

  In this way, in the case where one door plate 12 is hinged to the vertical frame 2, when the other door plate 12 is moved on the rail 4, the folding door 10 is opened and closed while the connecting portion 11 is moved by the hinge 11a. The

  The folding door 10 of the present invention can also be applied to any door plate 12 that constitutes the folding door 10 without being hinged to the vertical frame 2 and both the door plates 12 moving on the rail 4. The folding door is not limited to a pair of door plates, and a plurality of pairs may be connected. In that case, although doorboards are connected also on the rail 4, the connection part is not contained in the connection part 11 said by this specification.

  In each door plate 12 constituting the folding door 10, a handle 12 ab is mutually connected to a door plate front surface 12 c in the protruding direction of the folding door 10 (the connecting portion 11). It is formed so as to protrude opposite to. Hereinafter, the protruding direction is referred to as the front, and the opposite direction is referred to as the rear.

  Each of these handles 12ab is formed on the front surface 12c of the door plate 12 in the vertical direction. A recess 12ac is formed behind the door 12b, and a finger can be put into the recess 12ac to pull the handle 12ab. I am doing so.

  When the folding door is closed, the handle 12ab conceals part of the recess 12ac from the front, and the two recesses 12ac are adjacent to each other so that fingers can be inserted into the recess 12ac. An opening 16 extending in the vertical direction is formed, exposing the central portion of the adjacent recess 15.

  The connecting end portion 12a of the door plate 12 behind the adjacent recess 15 is formed with an abutting end portion 12aa that is abutted against each other when the folding door is closed, and a gap of several mm wide when the folding door is closed therebetween. 14 is formed, and the space of the gap 14 expands so that the fan opens with the opening operation of the folding door 10 and contracts so that the fan closes with the closing operation.

  A hinge 11a, which is a constituent member of the connecting portion 11, is attached to the rear surface 12d of the two door plates 12, and a hinge pin of the hinge 11a allows the two door plates 12 to be folded at the connecting portion 11 so as to be freely connected. Configure.

  In this embodiment, as shown in FIG. 3, the hinge 11a is attached at three locations in the upper, lower, and center in the vertical direction. As shown in the enlarged view of FIG. 1, the hinge 11a operates smoothly. Therefore, when the folding door is opened to some extent, a predetermined gap 13 formed by the connecting fulcrum 11b is located behind the gap 14 and between the connecting end portions 12a (the rear corner portions 12ad) of the two door plates 12. Is formed.

  Further, a finger clogging prevention tool A is disposed and fixed to the connecting portion 11 so as to pass through the gap 14 and straddle the front and rear thereof. This finger clogging prevention tool A is composed of a shielding body 20 made of a plate-like body that partially covers the gap 14 from the front, and a plate-like body for fixing the shielding body 20 to the door plate 12. The fixture 30 is combined and integrated.

  In the present embodiment, the shield 20 is not provided over the entire height of the folding door 10, but as shown in the front view of the folding door 10 in FIG. According to the height of the door plate, a length corresponding to a position slightly higher than the center from the lower end position of the door plate 12 is disposed. On the other hand, as shown in the rear view of the folding door 10 in FIG. 3, several sets of the fixing tool 30 are attached to the positions excluding the attachment location of the hinge 11a by screws.

  The shielding body 20 has a bent portion 21a at the center and mounting bent portions 21b and 21b at both side ends so that it can be folded and unfolded. An extending attachment portion 22 is provided over the entire length. The mounting portion 22 includes mounting pieces 22a and 22a extending from both side ends of the operating piece 21, and further connected portions 23 and 23 to which the fixing tool 30 is connected to both side ends (see FIG. 4 (a) and FIG. 5).

  4 (a) and 5 show the front as viewed from the front of the folding door, similar to FIGS. 2 and 3 showing the state of being attached to the door plate 12. FIG. Therefore, in these drawings, the upper surface of the shield 20 in the drawing indicates the mounting surface for the door plate 12, and the lower surface indicates the protruding direction surface of the connecting portion 11 of the folding door 10.

  The actuating piece 21 has a pair of shielding pieces 21c and 21c that operate symmetrically on both sides of the bent portion 21a. When the finger clogging prevention tool A is attached to the door plate 12, the shielding piece 21c. , 21c is configured to be folded and unfolded while the central bent portion 21a and the attached bent portions 21b and 21b on both sides are bent and changed in accordance with the opening / closing operation of the folding door 10.

  In addition, when the folding door 10 is not opened (fully opened) and the end surfaces 12aa of the butted end portions 12aa are both oriented in the direction perpendicular to the guide rail 4, the operating piece 21 has the shielding pieces 21c on both sides of the bent portion 21a. , 21c is an obtuse angle, and has a width dimension protruding slightly forward.

  The shield 20 is formed of a flexible resin material so that the central bent portion 21a and the attachment bent portions 21b and 21b on both sides can be bent, and other portions are formed of a hard resin material. Therefore, it is desirable to manufacture by two-color molding using different materials.

  Moreover, although the site | part except the to-be-connected part 23 of the shield 20 is a substantially flat form as shown to Fig.4 (a) in the expand | deployed state, it is attached to the doorplate 12 and the operation piece 21 is attached. The bent portion 21a is arranged in a protruding direction of the folding door 10 so as to be able to vary between the flat plate state developed and the folded portion 21a protruding forward (downward in FIG. 4A). It is bent so as to protrude in the same direction.

  In this embodiment, when in a return state where no external force is applied, the operating piece 21 protrudes slightly, the angle formed by the shielding pieces 21c and 21c becomes an obtuse angle, and has a V shape close to a flat plate shape. The operating piece 21 is folded and polymerized by energizing the elastic force from both ends. The shield 20 may be one that does not generate a return elastic force when folded by applying the external force as described above, and at least the bent portion 21a and the mounting bent portion 21b of the operating piece 21 can be bent. Any device that can move between the expanded state and the folded state may be used.

  Further, the connected portion 23 of the mounting portion 22 of the shield 20 is bent and overlapped at the end of the plate-like body so as to protrude in the direction orthogonal to the mounting piece 22a from the end of the mounting piece 22a. The insertion groove 23b formed by the superposed two pieces of sandwiching pieces 23a and 23a is formed on the side of the attachment surface to the door plate 12.

  On the other hand, the fixture 30 is a plate-like fixing piece 32a having a screw hole 32b that is formed by forming a metal plate such as stainless steel in a substantially U shape and is fixedly attached to the rear surface 12d of the door plate 12. And a connection support portion 31 having a connection piece 31c for connection to the attachment portion 22 of the shield 20 are integrally provided.

  The connection support portion 31 includes a connection piece 31c at its end, a support piece 31b that is bent and extended from the base end of the connection piece 31c and is disposed along the front surface 12aab of the butted end portion 12aa, and its support A bridging piece 31a is provided that bridges the piece 31b and the fixed piece 32a and is arranged along the end face 12aa of the butt end 12aa.

  The fixed piece 32a and the support piece 31b are formed so as to be parallel to each other, and the distance between the fixed piece 32a and the support piece 31b is a size that can be fitted to the butt end portion 12aa of the door plate 12. That is, the fixing tool 30 is attached to the door plate 12 so that the butted end portion 12aa of the connecting end portion 12a of the door plate 12 is sandwiched by the U-shaped portion formed by the fixing portion 32 and the connecting support portion 31.

  As shown in FIG. 5 and the like, the fixture 30 has a difference in that the connecting piece 31b is formed on the connected portion 23 of the shield 20 so that the open end of the fixing portion 32 faces the side end of the shield 20. It is inserted into the insertion groove 23b and integrated. The connecting piece 31c has a bent shape as shown in FIG. 4B and the like, and is fitted into the insertion groove 23b of the connected portion 23 by press-fitting to constitute a connecting and fixing portion B.

  As described later with reference to FIGS. 9 and 10, the finger clogging prevention device A in which the two members are integrated as described above is a state in which the U-shaped fixture 30 is joined and folded in a state of being folded together. Is attached to the rear surface 12d of the door plate 12, and the connected portion 23 of the shield 20 with the connecting piece 31c of the fixture 30 inserted therein is recessed. Further, the mounting piece 22a is arranged in the vicinity of the side wall 12ae at the back of the 12ac and along the side wall 12ae, and the mounting piece 22a is further forward of the support piece 31b in close contact with the front surface 12aab (see FIGS. 9 and 10). Polymerized on the side.

  In the state where the fixture 30 is attached to the butted end portions 12aa and 12aa of the door plates 12 and 12, both the shielding pieces 21a and 21a of the operating piece 21 of the shielding body 20 are located at any part of the door plate 12. When the folding door 10 is opened and closed, the folding and unfolding operations are possible.

  In this way, the finger clogging prevention tool A is fixed to each of the adjacent door plates 12 and 12 by the fixing tool 30, and the fixing position thereof is the bridge between the end faces 12 aa and 12 aa of the both butted ends 12 aa and 12 aa. In order to prevent the entanglement pieces 31a and 31a from being superposed, the height positions are made different from each other as shown in FIGS. When the folding door 10 is closed, the width of the gap 14 between the butt end portions 12aa and 12aa is wide enough to operate smoothly even when the bridge pieces 31a and 31a are overlapped. It may be arranged.

  Next, the basic operation of the finger clogging prevention tool A will be described with reference to FIGS.

  6 to 8 show state transitions of the connecting portion 11 when the folding door 10 is closed (from the state X1 in FIG. 1 to the state X2 through the state X2) (corresponding to the state X3 of the left folding door in FIG. 1). It is the partial cross section figure of the connection part 11 which showed the transition to a state) according to figure order according to the time series.

  In the state in which the folding door 10 is almost fully opened, the two door plates 12 are folded so as to overlap each other, and the end surface 12aa of the butt end portion 12aa faces forward. As described above, since the operating piece 21 has a slightly larger width, the operating piece 21 protrudes forward in a mountain shape with the bent portion 21a as the apex. In this state, since the folding door 10 is in a fully open state, the operating piece 21 is not further expanded and becomes flat.

  Thus, since the operating piece 21 of the shield 20 protrudes slightly forward in the opened state of the folding door 10, when the folding door 10 shifts to the closing operation from that state, the operating piece 21 is bent backward. There is no fear, and it is possible to shift to a folding operation as will be described later.

  Thereafter, when the folding door 10 is gradually closed, the angle θ2 formed by the operating piece 21 and the mounting piece 22a in the mounting bent portion 21b of the operating piece 21 gradually increases as the folding door 10 is closed. The angle θ1 formed by the shielding pieces 21c and 21c in the bent portion 21a becomes small and varies so that the operating piece 21 is folded (see FIGS. 6B, 7 and 8).

  Thus, when the folding door 10 is closed to a closed (fully closed) state, the operating piece 21 is formed along the protruding direction of the folding door 10 at the center of the adjacent recess 15 where the recesses 1ac, 12ac of the door plates 12, 12 are adjacent. Is sharpened at the tip (folded portion 21a) and folded into a superposed state so as to block between the recesses 1ac and 12ac, and the bent portion 21a at the tip is slightly more than the opening 16 between the handles 12ab and 12ab. Jump out.

  Thus, in the folding operation process of the operating piece 21, the operating piece 21 is always in a state of covering the gap 14 between the abutting end portions 12aa and 12aa and concealing the end face 12aa of the abutting end portion 12a. It is possible to reliably prevent a finger from entering the gap 14 or the gap 13 behind it by mistake.

  Further, in the closed state of the folding door 10, the folded working piece 21 protrudes forward in the shape of a point, but since the working piece 21 is almost housed in the adjacent recess 15, it is aesthetically pleasing. There is no problem, and there is no possibility that the body or the like is caught on the protruding operating piece 21.

  In the finger-clog prevention tool A of the present embodiment, the folded portion 21a that is the tip of the folded operating piece 21 protrudes slightly from the opening 16 between the handles 12ab and 12ab when the folding door 10 is closed. However, it is desirable that the entire operation piece 21 is accommodated in the adjacent recess 15. In order to do so, the dimensions of the recess 12ac, the butted end 12aa of the door plate 12 and the operating piece 21 of the shield 20 may be adjusted as appropriate.

  Further, when opening the closed folding door 10, a finger is put into one of the recesses 12ac from the opening 16 and the handle 12ac is pulled. However, since the operating piece 21 is thinly folded, the recess 12ab and the opening 16 are opened. Is not blocked by the shield 20, and the operating piece 21 does not interfere with putting a finger into the recess 12ab, and the pulling operation of the handle 12ac can be performed without difficulty.

  Moreover, since the screw stop of the fixing tool 30 is made on the rear surface 12d of the door plate 12, the screw is not visible from the front, so that it looks good. In addition, when the folding door 10 is in the closed state, the connected portions 23 at both ends of the shield 20 are hidden by the handle 12ab, so that the shield 20 does not impair the aesthetics, and particularly the color of the shield 20 If the pattern is matched to the door plate 12 and provided over the entire height of the door plate 12, there is no sense of incongruity due to the provision of the anti-fingering tool A.

  Next, an example of a method for mounting the finger clogging prevention tool A to the connecting portion 11 of the folding door 10 will be described with reference to FIGS. 9 and 10.

  First, the front surface 12c of one door plate 12 is placed on the work table W in a state in which the folding door 10 to which the hinge 11a is attached and the connecting portion 11 is formed is folded. That is, the folding door 10 in this state is the same as a state where the folding door 10 is fully opened when the folding door 10 is constructed, and the door plate 12 is polymerized.

  Next, the bridging piece 31a butts the fixing portion 32 (fixing piece 32a) of the fixing member 30 for the lower door plate 12 of the finger clogging prevention device A from the gap 13 of the butt end portion 12aa that overlaps vertically. It is inserted and temporarily fixed until it hits the end surface 12aa of the end portion 12aa. In this state, the connected portion 23 of the shield 20 and the connecting piece 31c of the fixture 30 that are fitted to each other are arranged in the back of the recess 12ac and in the vicinity of the side wall 12ae in the back of the recess 12ac. (See FIG. 9 above). As shown in FIG. 3, when a plurality of fixing tools 30 are provided for fixing to the door plate 12, the plurality of fixing tools 30 can be inserted at the same time, so that the mounting can be performed efficiently.

  Further, the upper fixing member 30 for the door plate 12 is also attached to the door plate 12 by the same method and temporarily fixed (see FIG. 10).

  In this way, after temporarily attaching the antifouling tool A to the folding door 10, the upper door plate 12 is pivoted to the right in FIG. 9 and FIG. For all of the fixing tools 30, the fixing portion 32 is screwed to the rear surface of the door plate 12, and the finger plugging prevention tool A is fixed to the folding door 10 (this state is not shown).

  Thus, after the anti-fingering tool A is mounted and fixed to the folding door 10 and the folding door 10 is constructed, the folding door 10 is in an open state (see, for example, FIGS. 6A, 6B, and 7A). ) And the operating piece 21 of the shield 20 is pulled forward (in the width direction of the door plate 12), the connecting and fixing part B of the shielding body 20 and the connecting piece 31c of the fixing tool 30 are connected to the connecting and fixing part B. However, since it is fitted and connected along the thickness direction of the door plate 12, there is no possibility that the shield 20 will come off. In addition, even when the folding door 10 is in the closed state (see FIG. 8B) and the operating piece 21 is pulled, the protruding end of the connected portion 23 is gripped even if the attachment piece 22a is elastically floated. In addition, the connecting piece 31c is press-fitted to the connected portion 23, so that the connected portion 23 is not detached from the connecting piece 31c and is in a floating state. 22a also elastically returns.

  Of course, since the fixing tool 30 is screwed in a state where the butted end portion 12aa is sandwiched, there is no possibility that the fixing tool 30 itself is displaced by pulling the shield 20 in the closed state of the folding door 10.

  As described above, the finger clogging prevention tool A has a U-shaped fixing tool 30 and sandwiches and fixes the butt end portion 12aa of the door plate 12, and is thus firmly fixed to the connecting portion 11 of the folding door 10. The

  In addition, since the shielding body 20 and the fixing tool 30 constituting the finger clogging prevention tool A are both plate-shaped bodies, the gap 14 or the like of the connecting portion 11 is used even when connected as a folding door. And can be easily attached.

  In addition, this anti-clogging tool A can be stabilized in the open or closed state in which the folding door 10 is erected, so that it can be easily mounted on the folding door 10 before shipping, etc. For the folding door 10 as well, the finger clogging prevention tool A can be retrofitted in the same procedure as described above.

  In the embodiment described above, the anti-clogging device A is shown in which the butted end portion 12aa of the door plate 12 can be firmly sandwiched and fixed by the fixing device 30, but the anti-clogging device having another structure as shown in FIG. It may be.

  For example, in the finger clogging prevention tool A of FIG. 11A, the fixing tool 30 is substantially L-shaped, and the connecting and fixing portion B between the shield 20 and the fixing tool 30 is covered by the connecting piece 31c and the shield 20. The connecting portion 23 is formed in the vicinity of the corner portion of the front surface 12aab of the butt end portion 12aa. Thus, even if the fixing device 30 does not sandwich the butt end portion 12aa, if a highly rigid material is used for the fixing device 30 and the connection between the connecting piece 31c and the connected portion 23 is strengthened, the shielding body There is no hindrance to the operation of 20 and there is no possibility that the shield 20 will come off. Moreover, the mounting to the folding door 10 is easy.

  In addition, the finger clogging prevention tool A in FIG. 11B does not use the plate-shaped fixing tool as described above, and directly fixes the shield 20 having a shape similar to that employed in the above embodiment, such as a screw. It is fixed with the tool 30. For example, as shown in the drawing, if one door plate 12 is screwed with a side wall 12ae at the back of the recess 12ac and a front surface 12aab of the butt end portion 12aa, prevention of finger clogging can be realized with a simple structure.

  Furthermore, the finger clogging prevention tool A in FIG. 11C does not use a plate-like fixing tool, and the shielding body 20 has a simple shape and may be composed of only the operating piece 21. For fixing to the chamfered portion 12aac, the mounting portion 22 slightly extended from the mounting bent portions 21b on both side ends of the operating piece 21 may be bonded to the chamfered portion 12aac of the butt end portion 12aa. Moreover, it is good also as a structure which can engage the attaching part 22 directly with the chamfering part 12aac.

  In these drawings, the same components as those in the above embodiment are denoted by the same reference numerals and description thereof is omitted.

  Thus, if it has the shielding body 30 which folded and unfolded and concealed the gap | interval 14, in addition to the thing of the simple structure which is illustrated in FIG. Tool A may be sufficient.

  Even with such a simple structure, the operating piece 21 of the shield 20 is folded along the protruding direction of the folding door at the approximate center of the adjacent recess when the folding door is closed, whereas it is unfolded when the folding door is closed. The operating piece 21 does not get in the way and the pulling operation of the handle 12ab does not become difficult.
