By the way, the folding door is suspended by a roller that rolls on the rail member provided on the upper part, and the door-end side panel and the door-end side panel are connected via an intermediate connecting body so that they can rotate at an equal angle. A narrow sleeve panel is arranged on the side of the door-end side panel, and the door-end side panel and the side hinge are directly connected so as to be freely rotatable. In the case of a folding door opening / closing mechanism that moves, it is necessary to set a space portion having an area for allowing initial linear movement between the side edge of the door butt side and the end of the door butt side panel. Since the space portion is narrowed when the folding door is opened, measures for preventing finger clogging must be taken. However, the above Patent Documents 2 and 3 do not provide such a finger plugging prevention function in the space.

Therefore, in view of the above-described situation, the present invention intends to solve the problem by connecting a plurality of panels with hinges and linearly moving along the rails at the initial stage of the opening operation. In the folding door opening / closing mechanism in which a space portion having a width for allowing initial linear movement is set between the end portions of the buttocks side panel, it is possible to reliably prevent finger jamming even when the space portion is narrowed when the folding door is opened. The object is to provide an anti-fingering device.

In order to solve the above-mentioned problems, the present invention connects a plurality of panels with hinges, moves linearly along the rails in the initial stage of the opening operation, and the door bottom side panel and the door side panel rotate from the middle. Then, in the folding door opening and closing mechanism in which a space portion having a width for allowing initial linear movement is set between the side edge of the door bottom side and the edge of the door bottom side panel, the side edge on the door bottom side is It has a substantially L-shaped cross section, has a blindfold wall portion along the rail on one side of the front and back, and an end face wall portion that forms a terminal end of the frontage, and the blindfold wall portion in the closed state of the folding door And the end of the door butt side panel are in a state of overlapping in the front and rear with a small gap so that there is no risk of fingering, and the side of the side lamp corresponding to the door butt side end of the door butt side panel the inner part of the end wall portion, the initial linear phase than the front portion of the end wall portion corresponding to the front and back the other side of the side stiles To constitute a finger packed prevention device in the finger packed prevention device in Orito closing mechanism, characterized in that the formation of the recessed portion is retracted to the direction (claim 1).

Here, the blind wall notch on the door trailing side panel side edge of provided, it is preferable that the wearing the packing cutout section (claim 2).

  And from the elastic material for abutting the door edge side panel when the folding door is opened to the front upper and lower ends of the end face wall part that forms the terminal end of the front edge part at the side edge of the door edge side It is more preferable that the buffer member to be projected is provided (claim 3).

Further, the door-end side panel is rotatably connected to the sleeve panel that is linearly moved along the rail, and the end-side structure of the rotary connection side of the sleeve panel is formed from a side end surface of the sleeve panel. Forming a guide portion having a cylindrical surface or a curved surface close to the cylindrical surface with the rotation center as the central axis toward the front surface side where the rotation rotates, and a joint member provided at a side end of the door-end side panel and the surface of the guide portion It is also preferable that the distance between the two is kept so narrow that a finger does not always fit (claim 4).

Further, as the folding door opening / closing mechanism, the door bottom side end portion of the door bottom side panel is suspended on the rail so as to be movable by the door bottom side suspension support body, and the folding door provided at the door bottom side end portion is opened. Pivoting means for forcibly pivoting the door-side panel in the opening direction, and the pivoting means rotates the door-side panel around the cam gear with respect to the door-side suspension support. A short rack with which the cam gear meshes is fixed to the upper arm while being movably connected to the door-side panel so as to coincide with the pivot center that is movably coupled, and the cam gear further has a constant rotation angle. A stopper is provided on the door butt side panel that restricts it to rotate only, and it moves linearly along the rail in the initial stage of opening the folding door, and the door butt side panel and the door side panel rotate from the middle. It is also preferable to do so (claim 5).

According to the finger-clogging prevention device in the folding door opening / closing mechanism of the invention according to claim 1 as described above, the plurality of panels are connected by hinges, moved linearly along the rails at the initial stage of the opening operation, and the door bottom side from the middle Folding door opening and closing mechanism with a space that has a space to allow initial linear movement between the side edge of the door butt side and the edge of the door butt side panel, with the panel and door side panel rotating. The side edge of the door butt side has a substantially L-shaped cross-section, and has a blindfold wall portion along the rail on one side of the front and back, and an end face wall portion that forms the end of the frontage portion. In the closed state of the folding door, the blindfold wall and the end of the door butt side panel are overlapped in the front and back with a small gap so that there is no risk of finger filling, the inner part of the end wall portion of the side rail corresponding to trailing edge, the front and back the other side of the side stiles By that is retracted into the corresponding initial linear movement direction than the front portion of the end wall portions forming a recess, can secure a space portion sufficiently wide to allow the initial linear movement, yet open Orito Even when the distance between the side heel and the door butt side end of the door butt side panel becomes the narrowest at the time of operation, it is possible to protect by retracting the finger due to the presence of the recessed portion, and the back of the side ledge Since the concave portion is formed in the front side, the front side portion of the side flange protrudes into the frontage portion, and a part of the space portion can be hidden, so that the appearance can be improved. In addition, when the folding door is closed, the blindfold wall and the edge of the door butt side panel are overlapped in the front and back with a small gap so that there is no risk of finger filling, Since the blindfold wall portion and the end of the door butt side panel always overlap each other, it is not seen through, and the blindfold wall portion has a small gap with respect to the door butt side panel, so there is no fear of finger jamming.

According to claim 2, when the folding door is opened, the door end side end portion of the door end side panel connected to the door end side panel or the end portion of the sleeve panel connected to the door end side panel is the end portion of the blindfold wall portion. Although approaches, the at edges of the blind wall portion provided with the door trailing side panel side notch, since wearing the packing cutout section, if the end portion and the other moving parts of the blind wall portion Even if a finger is sandwiched between them, the packing can be deformed and retracted into the notch to protect the finger.

  According to claim 3, when the folding door is opened, the door edge side panel is abutted to the front upper and lower end portions of the end face wall portion that forms the terminal end of the front edge portion with the side edge of the door edge side. Since the buffer member made of an elastic material is provided so as to protrude, if the protruding height of the buffer member is made higher than the thickness of the finger, finger padding can be prevented immediately before the folding door is opened.

According to claim 4, the door-end side panel is rotatably connected, and is an end portion structure on the rotary connection side of the sleeve panel that moves linearly along the rail, from the side end surface of the sleeve panel. Forming a guide portion having a cylindrical surface with a rotation center as a central axis or a curved surface close to the cylindrical surface toward a front surface side where the door-end side panel rotates, and a joint member provided at a side end of the door-end side panel; Since the distance from the surface of the guide portion is always kept so narrow that a finger does not fit, the risk of pinching the finger at the pivotal connecting portion between the door side panel and the sleeve panel can be completely eliminated. it can.

According to the fifth aspect, when the folding door starts to open from the closed state, the cam gear first rotates freely with respect to the door-end side panel while being engaged with the rack, and as a result, the door-end side panel follows the rail. The cam gear is then rotated by the stopper, but the cam gear is continuously rotated by the rack so that the cam gear rotates together with the door bottom panel. The panel can be forcibly rotated in the opening direction.In other words, when the cam gear meshes with the rack and the rotation of the cam gear is restricted by the stopper, the door-side panel does not rotate. There is no unexpected linear movement along the rail.

  Next, the present invention will be described in more detail based on the embodiments shown in the accompanying drawings. FIG. 1 shows the whole folding door apparatus according to the present invention, and FIGS. 2 to 4 show details of the folding door apparatus, in which 1 is a folding door, 2 is a side wall on the door end side, and 3 is a side on the door bottom side.框 and 4 respectively indicate upper heels.

  And the said folding door 1 connects the door tip side panel 5 and the door bottom side panel 6 via the intermediate connection body 7 so that equiangular rotation is possible, and a width | variety is narrow at the side part of the said door tip side panel 5 The sleeve panel 8 is arranged, and the door-end side panel 5 and the side hinge portion 9 are directly connected so as to be freely rotatable.

  The intermediate connector 7 is configured by connecting the upper and lower ends of the oblong blocking member 10 to the upper and lower ends of the side portions of the door-end side panel 5 and the door-end side panel 6 with equiangular hinges 11, 11, respectively. . Here, the closing member 10 has cylindrical portions 10A and 10A on both sides, and has a shape in which the middle is integrated by a connecting portion 10B. The equiangular hinge 11 is configured so that the two wings 11B and 11B protruding from the main body 11A are rotated by the same angle, and the wings 11B and 11B are connected to the door side panel 5 and the door butt. Screw on the upper and lower ends of the side of the side panel 6. The center of rotation in the intermediate connector 7 is the center of each cylindrical portion 10A of the closing member 10, and the joint members 12 made of the same mold material are used at the side ends of the door-end side panel 5 and the door-end side panel 6. A part of the cylindrical portion 10A is received in a non-contact state between a pair of protrusions 12A and 12A having a substantially C-shaped cross section projecting on both side edges of the joint member 12 to prevent light leakage and finger clogging. I am trying.

  Further, the side hinge portion 9 forms a guide portion 13 having a cylindrical surface or a curved surface close to the cylindrical surface with the rotation center as the central axis from the side end surface of the sleeve panel 8 to the front surface side. The upper and lower ends of the door and the side upper and lower ends of the door-end side panel 5 are connected by free hinges 14 and 14 so as to be rotatable. The rotation center of the side hinge portion 9 is a position corresponding to the radius of curvature of the guide portion 13, and the joint member 12 similar to the above is attached to the side end of the door-end side panel 5. Both the protruding pieces 12A and 12A are arranged close to the surface of the guide portion 13 to prevent light leakage and finger clogging. In other words, the interval is set so that the surface connecting the tips of the two projecting pieces 12A, 12A of the joint member 12 intersects the guide portion 13, but the joint member 12 and the guide portion 13 are made very close in this way. Thus, there is no room for a finger to enter the gap. The front side of the guide portion 13 slightly protrudes from the front side of the sleeve panel 8, which is the operation of the joint member 12 up to an angle of 90 ° at the maximum with respect to the sleeve panel 8. This is to allow rotation while securing the locus.

  A door stop 15 made of a soft material is attached to the end of the sleeve panel 8 on the door-end side, and handles 16 and 16 are provided on both front and back surfaces. On the other hand, as shown in FIG. 3 and FIG. 13, the back part of the side sword 3 corresponding to the door butt side end of the door butt side panel 6 is retreated from the front side part 17 to the initial linear movement direction side. The recessed portion 18 is formed, and the recessed portion 18 can secure a sufficiently large space S for allowing the initial linear movement. Further, when the folding door is opened, the side wall 3 and the door bottom side panel are operated. Even when the distance between the door and the rear end of the door 6 is the narrowest, the presence of the recessed portion 18 allows the finger to be retreated with a margin to protect it. In addition, since the recessed part 18 was formed in the back part of the said side sword 3, the front side part 17 of the side sword 3 will be in the state protruded in the front part, and the door sill side edge part of the said sill side panel 6 and the side sword 3 Since a part of the space portion S can be hidden, the space portion S looks narrow when viewed from the front side, so that the appearance can be improved.

  Next, the opening / closing mechanism of the folding door 1 will be described. As shown in FIGS. 1 and 2, a rail member 19 made of an aluminum extrusion mold material is laid across the entire front opening inside the upper collar 4, and a single rail 20 integrally formed with the rail member 19 is attached to the sleeve 20. The door-end side suspended support body 21 provided at the upper end of the panel 8 and the door-end side suspension support body 22 provided at the upper end of the door-end side end portion of the door-end side panel 6 are suspended movably.

Then, a wire (not shown) fed from a constant load spring device 23 provided at the door end side end of the rail member 19 is connected to the door end side suspension support body 21 so that the folding door 1 extends. In other words, it is energized with a constant load in the closing direction. Further, the door leading end side hanging支体21 is provided with a rotary damper 24 having a horizontal axis of rotation, juxtaposed along the rail 20 to the end portion of the door leading side and the door trailing end side of the rail member 19 Rack the rotary damper 24 is adapted to mesh, respectively 25, 25. The door-side rack 25 and the rotary damper 24 function to slow down the operation from immediately before the folding door 1 is closed until the door 1 is closed, while the door-side rack 25 and the rotary damper 24 are open. The function of delaying the closing operation of the folding door 1 is achieved, and when a person on a wheelchair or a person who moves by pushing an infusion device enters or exits by his / her own operation, an allowance time for passage is secured.

Next, the guide device in the folding door opening / closing mechanism of the present invention will be described in more detail. The folding door 1 can be opened by bending the portion where the door end side panel 5 and the door bottom side panel 6 are connected by the intermediate connecting body 7 to one side of the front and back, but with the handle 16 An additional function is required to cause the folding operation of the folding door 1 only by moving the sleeve panel 8 along the rail 20. In the present embodiment, immediately after the folding operation of the folding door 1, the whole moves linearly along the rail 20 , and then the door end side panel 5 is kicked out of the plane by the kicking means 26 and the door bottom side panel 6. The door is forcibly rotated in the opening direction by the rotating means 27 provided at the end of the door bottom.

  Specifically, the kick-out means 26 has a structure in which a pin 26A provided on the upper end of the left and right intermediate portion of the door-end side panel 5 is slid and extruded on an inclined surface of a guide block 26B provided on the upper collar 4. . Here, when the folding door 1 is in the closed state, the pin 26A is engaged with the guide block 26B. Therefore, even if a force is applied to the door-end side panel 5 and the door-end side panel 6 from the out-of-plane direction, The closed state is stably maintained without shaking.

  Further, the rotating means 27 coincides with the center of rotation of the cam gear 27A having a substantially fan shape in plan view, the center of which is connected to the door-side suspension support 22 so as to be rotatable. The short rack 27B meshed with the cam gear 27A is fixed to the upper collar 4 while the cam gear 27A is rotated by a certain rotation angle. A stopper (not shown) is provided on the door-side panel 6 so as to restrict it. Therefore, when the folding door 1 starts to open from the closed state, first, the cam gear 27A is freely rotated with respect to the door-end side panel 6 in a state where the cam gear 27A is engaged with the rack 27B. The rotation of the cam gear 27A is then restricted by the stopper, but the cam gear 27A is continuously applied with the rotational force by the rack 27B, so that the cam gear 27A rotates integrally with the door-side panel 6. Then, the door bottom panel 6 is forcibly rotated. Once the door-end side panel 5 and the door-end side panel 6 are bent, it can be bent in a more open direction with a light force thereafter.

  The door-end-side suspension support body 21 will be described with reference to FIGS. First, the rail member 19 is substantially L-shaped in cross section having a horizontal portion 19A and a vertical portion 19B. The rail member 19 is formed by raising the rail 20 on the edge of the lower horizontal portion 19A, and A guide groove 28 opened downward toward the rear of the lower surface of the portion 19A, that is, near the corner is formed, and an engagement groove 19C is formed on the front surface side of the upper edge of the vertical portion 19B. Here, the engagement groove 19 </ b> C is used for attaching the constant load spring device 23 and the racks 25, 25. The front and rear wall surfaces of the guide groove 28 are rail surfaces 28A and 28A, and an engagement piece 28B protruding forward is formed at the edge of the rail surface 28A on the rear side, that is, the corner side.

  The door-end side suspension support body 21 includes a substantially L-shaped suspension support fitting 29, two large and small rollers 30 and 31, and a detachment prevention member 32. A large-diameter roller 30 is rotatably attached to the side surface of the vertical substrate 33 of the suspension bracket 29, and the small-diameter roller 31 passes through the inclined long hole 35 formed with the substrate 33 through the rotation shaft 34. The nut 36 is screwed onto a screw shaft formed on the rotating shaft 34 so that the height can be adjusted. Then, a lower plate 37 bent at the lower end of the base plate 33 of the suspension bracket 29 is attached to the upper end surface of the sleeve panel 8 by screwing, and the large and small rollers 30 and 31 are attached to the rail 20 from the front side. Placed on. At this time, the height of the small diameter roller 31 is adjusted so that the sleeve panel 8 is horizontal. By placing the two rollers 30 and 31 in series on the rail 20 in this way, the left and right shaking of the door-end side suspension support body 21 is restricted.

  Instead of using the two large and small rollers 30 and 31, two rollers of the same size are arranged side by side on the tilting plate, and the tilting plate is pivotally attached to the side surface of the hanging support bracket 29 with a horizontal rotating shaft. You may do it. In this case, the posture of the sleeve panel 8 is determined by the center of gravity balance of the folding door 1.

  The detachment preventing member 32 has a pair of auxiliary rollers 39 and 39 each provided with a vertical rotation shaft on both sides of the upper surface of the horizontal piece 38A of the support plate 38, and has a vertical piece 38B on the front edge. is there. Two screw holes 40 are formed in the vertical piece 38B. Then, the auxiliary rollers 39, 39 of the disengagement prevention member 32 are inserted into the guide groove 28 of the rail member 19 from obliquely below in a suspended state in which the rollers 30, 31 of the suspension bracket 29 are mounted on the rail 20. Then, the horizontal piece 38A is raised horizontally and the vertical piece 38B is brought into contact with the back surface of the substrate 33. In this state, the horizontal piece 38A is slid along the rail member 19 and is perpendicular to the mounting holes 41 and 41 formed in the substrate 33. The screw holes 40, 40 of the piece 38B are aligned and screwed into the screw hole 40 through the screw 42 from the front to the mounting hole 41. The auxiliary rollers 39, 39 of the detachment preventing member 32 are guided by both rail surfaces 28A, 28A of the guide groove 28 and roll while maintaining a parallel state with the rail 20. Further, due to the presence of the engagement piece 28B of the guide groove 28, the auxiliary rollers 39, 39 will not fall out of the guide groove 28 after the support plate 38 is screwed to the suspension bracket 29. is there. The rail member 19 is supported horizontally via a horizontal rail 43 installed inside the upper rod 4.

  As described above, the door-end-side suspension support body 21 includes two rollers 30 and 31 arranged in series on the rail 20 and arranged in series at a position away from the rolling line of the rail 20. Since the two auxiliary rollers 39, 39 roll in the guide groove 28, it is possible to travel stably with the front and rear, right and left, and torsion being restricted with respect to the rail member 19. That is, as shown in FIG. 8, since the center line (rolling line) of the rail 20 and the position of the guide groove 28 are shifted forward and backward in the plane, the handle 16 is held when the folding door 1 is opened. When a force is applied in the lateral direction, a moment acts on the sleeve panel 8 in the direction of rotation, but the sleeve panel 8 can be moved along the rail 20 by the door-end side suspension support body 21.

  The door butt side suspension support body 22 has basically the same configuration as the door end side suspension support body 21, but as shown in FIG. One roller 46 is rotatably provided on the side 45, and is suspended from an upper end of the door-side panel 6 by a suspension shaft 48 perpendicular to the lower plate 47. A cam gear 27A constituting the rotation means 27 is rotatably mounted on the suspension support shaft 48. In addition, it attaches with the screw | thread 50 using the attachment holes 49 and 49 formed in the board | substrate 45 of the said suspension support metal fitting 44 using the same prevention member 32 as the above.

  The folding door opening / closing mechanism according to the present invention moves the sleeve panel 8 along the rail 20 with the handle 16 from the closed state shown in FIG. Is bent 180 ° through the intermediate coupling body 7 and protrudes at right angles from the side edge 3 on the door butt side in an overlapped state as shown in FIG. At the end of the opening operation of the folding door 1, the door-end side panel 5 and the door-end side panel 6 are folded, and at the same time, as shown in FIGS. A ball 53 elastically protruding from the lower end of the center of rotation of the door bottom panel 6 is received in the hole 52 of the plate 51 and protrudes into the door edge side end of the horizontal rail 43 as shown in FIG. The suspension support shaft 48 is received by the engaging portion of the provided movement restricting plate 54 to restrict further movement.

As shown in FIGS. 10 to 13, the side edge 3 on the door bottom side has a shape with a margin in consideration of the amount of movement because the folding door 1 moves linearly during the closing operation. It also serves as a door pocket frame. Specifically, the side bar 3 has a schematic shape with a substantially L-shaped cross section, a blindfold wall 55 along the rail 20 on one side of the front and back sides, and an end face wall 56 that forms the end of the frontage have. Then, the back portion of the end surface wall portion 56 of the side rod 3 is retracted to the initial linear movement direction side from the front side portion of the end surface wall portion 56 corresponding to the front and back other side portions of the side rod 3 to thereby form the recessed portion 18. In addition, a notch 57 is provided on the door butt side panel 6 side at the edge of the blindfold wall 55, and a packing 58 is attached to the notch 57. Here, the notch portion 57 is for securing a sufficiently wide space inward, and the packing 58 is made of a soft rubber or a porous material having soft elasticity that can be easily deformed. Even if a finger is sandwiched between these members, it is easily deformed so that the finger can be buried.

  Furthermore, shock absorbers 59, 59 made of an elastic material project from the upper and lower ends of the front side portion 17 of the end surface wall portion 56 of the side wall 3, and when the folding door 1 is fully opened, the door bottom side panel 6 In addition, a gap that is sufficiently wider than the finger is secured between the front side portion 17 and the surface of the door butt side panel 6. Further, as shown in FIGS. 8, 10 and 13, when a ridge 60 formed of an elastic material is formed on the side end surface of the sleeve panel 8, and the fold door 1 is fully opened, the ridge 60 is a door. The bottom panel 6 is designed to stop against the back of the door bottom side. The protrusion 60 absorbs an impact when the folding door 1 is fully opened, and is located between the protrusions 12A and 12A of the joint member 12 when the folding door 1 is closed to enhance the effect of preventing light leakage. belongs to.

Finally, the opening / closing operation | movement of the folding door which concerns on this invention is demonstrated based on FIGS. First, in the closed state shown in FIG. 10 and FIG. 12A, the packing 58 of the blindfold wall portion 55 and the end portion of the door butt side panel 6 have a slight gap , that is, a small interval so as not to cause a finger jamming. It is in a state where it has overlapped in the front and back. And since the recessed part 18 is formed in the said end surface wall part 56 corresponding to the door edge side edge part of the said door edge side panel 6, between the door edge side edge part of the said door edge side panel 6 is provided. A sufficiently large space S is secured.

  Then, when the folding door 1 starts to be opened, as shown in FIG. 12 (b), only the linear movement is initially performed. The space part S between the door edge side edge part 6 and the said end surface wall part 56 becomes narrow. At this time, although there is the highest risk of finger stuffing, since the recessed portion 18 is provided in the end face wall portion 56, a sufficiently large space portion S is always secured, so even if the finger is accidentally inserted, There is no risk of finger clogging.

  Further, when the sleeve panel 8 is moved to the side collar 3 side and the folding door 1 is opened, as shown in FIGS. 13 (a) and 13 (b), the side edge of the sleeve panel 8 is blindfolded on the side collar 3. The edge approaches the edge of the wall 55 and the interval is narrowed. At this time, the possibility of inserting a finger between the side edge of the sleeve panel 8 and the edge of the blindfold wall 55 cannot be denied, but even if a finger is inserted, the blindfold 55 Since the notch portion 57 is provided at the end edge and the packing 58 is attached to the notch portion 57, the finger can be protected by the packing 58. When the folding door 1 is fully opened, as shown in FIG. 11 and FIG. 13 (b), the cushioning member 59 provided at the side edge 3 of the door edge side panel 6 has its surface provided on the side wall 3. 59, and the ridge 60 projecting from the side end portion of the sleeve panel 8 on the back surface thereof.

  Further, as shown in FIG. 8, the protrusion 60 is slidably engaged from above and below in an engagement groove 61 formed in the side end portion of the sleeve panel 8, and the side hinge portion 9, The bearings 62 and 62 provided on the rotating shaft portion 9 are stopped and held. Further, as shown in FIGS. 12 and 13, the door edge side end portion of the door edge side panel 6 is formed with a stepped portion 63 at a corner portion facing the blindfold 55 of the side wall 3, Even when the door bottom panel 6 is rotated, it is arranged so as not to hit even if it is placed close to the blindfold 55. That is, it is possible to minimize the distance between the door-side panel 6 and the blindfold 55.

  Further, as shown in FIGS. 10 and 11, the intermediate coupling body 7 and the side hinge portion 9 also prevent finger filling. That is, only a slight gap is set between the cylindrical portion 10A of the closing member 10 or the guide portion 13 of the sleeve panel 8 and the projecting pieces 12A, 12A of the joint member 12, and always when the folding door 1 is opened and closed. Since a constant gap is maintained, there is no possibility of fingering.
