The threshold groove portion 24 extends from the wall portion 21 toward the door pocket 22. The lower end portion 11 of the sliding door 10 is accommodated in the threshold groove portion 24. When the lower end 11 of the sliding door 10 is accommodated in the sill groove 24, the sliding door 10 moves along the sill groove 24. The sliding door 10 is movable between a fully closed position P1 that fully closes the opening 20 and a fully open position P2 that opens the opening 20 to the maximum. In FIG. 1, the sliding door 10 in the fully closed position P1 is indicated by a two-dot chain line.

  FIG. 2 is a cross-sectional view showing the lower end portion 11 of the sliding door 10 and the vicinity of the lower end portion 11 along the line F2-F2 shown in FIG. FIG. 2 shows a state in which the lower end portion 11 of the sliding door 10 is cut along a plane perpendicular to the moving direction of the sliding door 10. As shown in FIG. 2, an accommodation groove 12 is formed at the lower end 11 of the sliding door 10. The housing groove 12 extends from one end to the other end in the moving direction of the sliding door 10.

  Here, a direction is defined for the sliding door 10. In a state where the sliding door 10 is installed in the opening 20, the vertical direction is defined V with one end on the side of the sill 23 as a lower end and the opposite side as an upper end. In the sliding door 10, a front-rear direction L is defined with one of the surfaces along the moving direction of the sliding door 10 as the front surface 13 and the other as the rear surface 14. In FIG. 1, the front side surface is the front surface 13. The moving direction of the sliding door 10 is M. The directions V, L, and M are orthogonal to each other.

  As shown in FIG. 2, the threshold groove portion 24 is formed to be large with respect to the thickness along the front-rear direction of the sliding door 10. This is because the sliding door 10 can be moved smoothly.

  An anti-shake pin 26 is provided on the bottom wall portion 25 of the threshold groove portion 24. The anti-shake pin 26 protrudes upward. The anti-shake pin 26 is housed in the housing groove 12 of the sliding door 10.

The upper wall portion 58 of the case 52 is provided with an engaging portion 52a with which the engaging claw portion 53b of the cover 53 is engaged.

  A boss portion 63 is formed on the inner surface of the rear wall portion 57 of the case 52. A through hole 64 through which the boss portion 63 passes is formed inside the stopper 51. The through hole 64 has a long hole shape extending in the vertical direction V. A through hole 65 is formed in the cover 53 at a position facing the boss portion 63 of the case 52 when the cover 53 covers the opening at the front end of the case 52.

  When the stopper 51 is accommodated in the case 52 and the cover 53 covers the front end opening of the case 52, the boss portion 63 penetrates the through hole 64 of the stopper 51 and at the edge of the through hole 65 of the cover 53. Abut.

  A hole 63 a is formed inside the boss portion 63. When the stopper 51, the case 52, and the cover 53 are combined as described above, the through hole 65 of the cover 53 communicates with the hole 63a of the boss portion 63. The screw 55 is a self-tapping screw. The screw 55 is inserted into the hole 63a in a state where the through hole 65 of the cover 53 and the hole 63a of the boss portion 63 communicate with each other. When the screw 55 is self-tapping, when the screw 55 is inserted into the hole 63a and rotated, the screw 55 is screwed into the boss portion 63 and fixed.

  The through hole 64 formed in the stopper 51 extends in the vertical direction V. For this reason, even if the boss 63 passes through the through hole 64, the stopper 51 can move in the vertical direction V with respect to the case 52 and the cover 53. The through hole 64 of the stopper 51 will be specifically described.

  FIG. 5 is an enlarged plan view showing the vicinity of a portion where the stopper device 50 is fixed in the sliding door 10. Since the stopper device 50 is housed in the housing groove 12 of the sliding door 10, it is indicated by a dotted line in FIG. In FIG. 5, the cover 53 and the bracket 54 are omitted to show the stopper 51.

  As shown in FIG. 5, the upper end of the through hole 64 contacts the boss 63 when the lower end surface 51 a of the stopper 51 is at the same position or slightly above the lower end of the case 52 and the cover 53 in the vertical direction. The position where the boss portion 63 abuts on the upper end of the through hole 64 is the position moved to the lowest position of the stopper 51. The position where the stopper 51 has moved downward is defined as a first position P3.

The other end portions of the front wall portion 69 and the rear wall portion 70 along the moving direction M are connected to each other by the side wall portion 71. One end portions of the front wall portion 69 and the rear wall portion 70 along the moving direction M are connected by a side wall portion 72. The side wall portion 72 is bent with respect to the front wall portions 69 and 70 along the front-rear direction.

  The side wall portion 72 of the bracket 54 is positioned inside one end along the moving direction M of the case 52 and the cover 53 when the case 52 and the cover 53 are accommodated in the bracket 54. For this reason, the case 52 and the cover 53 are formed with a groove 74 in which the side wall 72 of the bracket 54 is accommodated. In FIG. 4, only the groove 74 formed in the cover 53 is shown, but a similar groove is also formed in the rear wall 57 of the case 52. The lower ends of the groove part formed in the case 52 and the groove part 74 formed in the cover 53 are open.

  When the integrated body of the case 52, the cover 53, and the stopper 51 is inserted into the protection portion 68 of the bracket 54 through the upper end opening, the side wall portion 72 is inserted into the groove portion of the case 52 and the groove portion 74 of the cover 53.

  A through hole 75 is formed in the front wall portion 69 of the protection portion 68 of the bracket 54 at a position facing the through hole 65 of the cover 53. When the integrated body of the case 52, the cover 53, and the stopper 51 is accommodated in the protection part 68, the screw 55 passes through the through hole 75 of the protection part 68 and the through hole 65 of the cover 53, and the boss part 63. Screwed into the hole 63a. As a result, the case 52, the cover 53, the stopper 51, and the bracket 54 are integrally fixed by the screw 55. The case 52, the cover 53, and the bracket 54 constitute an example of the housing referred to in the present invention.

  As shown in FIG. 4, the fixing portion 67 is formed integrally with the protection portion 68. The fixing portion 67 protrudes along the movement direction M from the other end along the movement direction M of the protection portion 68, and is aligned with the protection portion 68 along the movement direction M. The fixing portion 67 includes a fixing surface portion 76 that is perpendicular to the vertical direction V. A through hole 77 that penetrates in the up-down direction V is formed in the fixed surface portion 76. The fixed surface portion 76 is fixed to the upper portion of the accommodation groove portion 12 of the sliding door 10 by a first fixing screw 78. The fixing screw 78 passes through the through hole 77.

  As described above, the bracket 54 holds the integrated body of the case 52, the cover 53, and the stopper 51 by the protective portion 68, and fixes the integrated body to the sliding door 10 by the fixing portion 67. In addition, a through hole 58 a through which the second fixing screw 80 is passed is formed in the upper wall portion 58 of the case 52. The through hole 58a extends along the moving direction M. The second fixing screw 80 is screwed into the wall portion of the receiving groove portion 12 through the through hole 58a. The stopper device 50 is also fixed to the sliding door 10 by the second fixing screw 80.

  As shown in FIG. 3, the height of the stopper device 50 along the vertical direction V is higher than the height of the accommodation groove 12 along the vertical direction V. The part in which the stopper device 50 is accommodated in the sliding door 10 is formed in a shape in which the stopper device 50 fits while including the accommodating groove 12.

  Next, it will be specifically described that the smooth movement along the vertical direction V of the stopper 51 is maintained by the bracket 54. The sliding door 10 is wooden. For this reason, the sliding door 10 may be warped due to the surrounding environment such as the humidity around the sliding door 10. As an example, the case 52 and the cover 53 of the stopper device 50 are made of resin. For this reason, when the sliding door 10 warps as described above, the stopper device 50 accommodated in the sliding door 10 may be deformed in accordance with the warping of the sliding door 10.

  The protective part 68 is made of metal and therefore has high rigidity. For this reason, even if the site | part in which the stopper apparatus 50 is accommodated in the sliding door 10 deform | transforms by curving as mentioned above, it can prevent that the protection part 68 deform | transforms because the rigidity of the protection part 68 is high. Or even if it deform | transforms, the extent of the deformation | transformation can be made small.

  When the case 52 and the cover 53 are deformed, the number of places where the stopper 51 comes into contact with the case 52 and the cover 53 increases, or the pressing force acting on the contact place increases. When the contact location increases or the pressing force acting on the contact location increases, the movement of the stopper 51 along the vertical direction V is hindered.

  However, since the deformation can be suppressed by the protective portion 68 or the degree of deformation can be reduced, the smooth movement of the stopper 51 is maintained. Further, the bracket 54 receives an impact input to the stopper 51 together with the stopper 51 when the stopper 51 comes into contact with the anti-shake pin 26.

  In addition, when the shape and structure which fixes the stopper apparatus 50 to the sliding door 10 can be provided not in the bracket 54 but in the case 52 and the cover 53, when the smooth movement of the stopper 51 is maintained without the bracket 54, Even if the bracket 54 is not provided, the bracket 54 may not be used when the stopper device 50 is not damaged by an impact when the stopper 51 abuts against the anti-shake pin 26.

An opening 79 is formed in the side wall portion 59 of the case 52 so that the operation portion 78 can move as the stopper 51 moves in the vertical direction when the stopper 51 is accommodated in the case 52. The operation unit 78 is accommodated in the opening 79.

  As shown in FIG. 3, one end of the stopper device 50 along the moving direction M is exposed from the end surface of the sliding door 10. The operation unit 78 is exposed to the outside from one end face along the moving direction M of the sliding door 10. For this reason, the operation part 78 can be easily operated from the outside. The operation on the operation unit 78 is to move the operation unit 78 up and down.

  As shown in FIG. 4, the stopper 51 and the case 52 are provided with a guide portion 81 that guides the movement of the stopper 51 along the vertical direction V. The guide portion 81 includes a guide protrusion 82 provided on the case 52 and a guide accommodating portion 83 provided on the stopper 51.

  The guide protrusion 82 is provided in the case 52 on the inner side and below the side wall 59 along the movement direction M, and extends in the vertical direction V. The guide accommodating portion 83 is provided on the inner side along the moving direction M from the end face on one end side along the moving direction M of the stopper 51, and the lower end is opened.

  When the stopper 51 is accommodated in the case 52, the guide protrusion 82 of the case 52 is accommodated in the guide accommodating portion 83 of the stopper 51. The length of the guide protrusion 82 along the vertical direction V is between the state in which the stopper 51 is in the first position P3 as shown in FIG. 5 and the state in the second position P4 as shown in FIG. When moving along the up-and-down direction V, at least a part of the guide protrusion 82 is long enough to be accommodated in the guide accommodating portion 83.

  In the range F61 in FIG. 5, the guide protrusion 82 and the guide storage portion 83 are enlarged and moved along the moving direction M in a state where the guide protrusion 82 is stored in the guide storage portion 83. The disconnected state is shown. As shown in the range F61, both end surfaces 84 and 85 in the movement direction of the guide protrusion 82 are planes perpendicular to the movement direction M and are parallel to the vertical direction V. Of the inner surface of the guide accommodating portion 83, both end surfaces 86 and 87 in the movement direction are perpendicular to the movement direction M and parallel to the vertical direction V.

  The guide accommodating portion 83 is slightly larger than the guide protruding portion 82. This is because the stopper 51 moves smoothly with respect to the case 52. In the state where the stopper 51 is accommodated in the case 52, the end face 85 on the other end side in the movement direction M in the guide protrusion 82 and the end face 87 on the other end side in the movement direction in the guide accommodation part 83 are parallel to each other. is there. Further, the end face 84 on one end side in the moving direction M of the guide protrusion 82 and the end face 86 on one end side in the moving direction M of the guide accommodating portion 83 are parallel to each other.

  As described above, the guide accommodating portion 83 is slightly larger than the guide protruding portion 82. However, the stopper 51 is brought into contact with the end surfaces 85 and 87 or the end surfaces 84 and 86 are brought into surface contact. The movement along the vertical direction V is guided.

  As shown in the range F61, the outer end surface 88 on one end side in the moving direction M of the guide accommodating portion 83 is a plane perpendicular to the front-rear direction L. An inner surface 89 of the side wall 59 of the case 52 is a plane perpendicular to the front-rear direction L. The inner surface 89 and the end surface 88 face each other. A gap S <b> 1 is provided between the inner surface 89 and the end surface 88. Even when the inner surface 89 and the end surface 88 are closest to each other, that is, the end surfaces 85 and 87 are in surface contact, the gap S1 is formed.

  Next, the operation of the finger pinching prevention device 40 when the sliding door 10 is opened from the fully closed position P1 to the fully open position P2 will be described. In FIG. 1, the sliding door 10 in the fully closed position P1 is indicated by a two-dot chain line. When opening the sliding door 10, the operator places his / her finger on the operation recess 18. In the range F12 of FIG. 1, the operation recess 18 and its vicinity are shown enlarged. In the range F12, the operator's hand 5 is indicated by a two-dot chain line.

  As shown in the range F <b> 12, when the operator moves the sliding door 10 to the fully open position P <b> 2, the operator generally presses the finger against the other end side in the moving direction of the operation recess 18. And it moves by pushing the sliding door 10 to the full open position P2 in the state which pressed the finger | toe to the moving direction other end side of the operation recessed part 18. FIG.

The stopper 51 of the stopper device 50 is held at the first position P3 by the biasing spring 56. When the sliding door 10 is moved toward the fully open position P2 while the stopper 51 is in the first position P3, when the sliding door 10 reaches the finger pinching prevention position P5, as shown in FIG. It abuts against an anti-blur pin 26 provided. When the stopper 51 comes into contact with the anti-shake pin 26, the sliding door 10 does not open any more. Here, the finger pinching prevention position P5 will be specifically described. The finger pinching prevention position P5 is a position that is considered so that fingers of the operator's hand are not pinched between the sliding door 10 and the door pocket 22 when the sliding door 10 is opened to the fully open position P2.

  In the present embodiment, the sliding door 10 is provided with the operation recess 18, and the finger of the operator's hand pressed against the inner surface of the operation recess 18 is drawn between the sliding door 10 and the door pocket 22. There is a fear.

  As shown in FIG. 1, in this embodiment, the finger pinching prevention position P <b> 5 is a position where the edge 18 a at the other end is flush with the opening side end face 22 a of the door pocket 22 along the moving direction M of the operation recess 18. is there. Being flush is the position where the edge 18a at the other end of the operation recess 18 in the moving direction and the end face 22a of the door pocket 22 overlap when the sliding door 10 is viewed from the front. For this reason, as shown in the range F <b> 12 of FIG. 1, the finger of the operator's hand is not drawn between the sliding door 10 and the door pocket 22 when the stopper 51 contacts the anti-shake pin 26.

  Although the above demonstrated the state which moved the sliding door 10 from the front surface 13 side, even if it is a case where the sliding door 10 is moved from the rear surface 14 side, the sliding door 10 stops similarly in the finger pinching prevention position P5.

  The finger pinching prevention position P5 may be set other than the above. For example, when the operation recess 18 is located away from the end surface 22a of the door pocket 22 so that the entire operation recess 18 is exposed when the sliding door 10 is viewed from the front to the rear, the stopper 51 and The anti-shake pins 26 may contact each other.

  When the movement of the sliding door 10 stops when the stopper 51 and the anti-shock pin 26 come into contact with each other, the operator moves the operation portion 78 of the stopper 51 upward. Since the opening 79 of the case 52 is open at the end surface of the sliding door 10, the operator can operate the operation unit 78 through the opening 79.

  As shown in FIG. 6, the operator moves the stopper 51 upward against the urging force of the urging spring 56. When the stopper 51 is lifted to the second position P4, the boss portion 63 comes into contact with the lower end of the through hole 64. By this contact, the operator can recognize that the stopper 51 has been moved to the second position P4. As another example, the upper end surface of the stopper 51 may abut on the upper end surface of the case 52 when the stopper 51 moves to the second position P4. In this case, the boss portion 63 may not be in contact with the lower end of the through hole 64. In this case, the operator can recognize that the stopper 51 has moved to the second position P4 by the upper end surface of the stopper 51 coming into contact with the upper end surface of the case 52.

  When the stopper 51 is moved to the second position P4, a space is provided between the stopper 51 and the bottom wall 25 of the sill 23 through which the anti-shake pin 26 can pass. The operator moves the sliding door 10 from the finger pinching prevention position P5 to the fully open position P2 as shown in FIG. 7 while maintaining the stopper 51 at the second position P4. FIG. 7 is a plan view showing the movement of the sliding door 10 as shown in FIG. When the stopper 51 is in the second position P4, the anti-blur pin 26 and the stopper 51 do not contact each other, and the sliding door 10 can be pushed into the door pocket 22.

  In the above description, the sliding door 10 is pushed into the door pocket 22 with the stopper 51 maintained at the second position P4. As another example, after operating the operating portion 78 to move the stopper 51 above the anti-shock pin 26, the sliding door 10 is moved to a position where the stopper 51 and the anti-shake pin 26 overlap in the vertical direction V. Then, the operation of the operation unit may be canceled.

  When the operation on the operation portion 78 is released, the stopper 51 is moved downward by the urging force of the urging spring 56, so that it comes into contact with the anti-shake pin 26 in the vertical direction V. However, since the lower end surface 51a of the stopper 51 is a plane perpendicular to the vertical direction V, the lower end surface 51a and the anti-shake pin 26 rub against each other. In this state, the sliding door 10 is pushed into the door pocket 22. Can do.

  In this case, since a frictional force is generated between the stopper 51 and the anti-shake pin 26, a force required for the movement of the sliding door 10 is increased. Therefore, preferably, the stopper 51 is moved to the second position P4 or When the sliding door 10 is moved in a state where it is positioned at a position where it does not contact the anti-blur pin 26 and the vertical direction V, the force required to move the sliding door 10 can be kept small.

  In the finger pinching prevention device 40 configured in this way, when the sliding door 10 reaches the finger pinching prevention position P5 when the sliding door 10 moves toward the fully open position P2, the stopper 51 and the anti-shake pin 26 come into contact with each other. As a result, the movement of the sliding door 10 is stopped.

  When the movement of the sliding door 10 is stopped, the operator operates the operation unit 78. For this reason, since the operator can recognize that there is a possibility that his / her finger may be pinched between the sliding door 10 and the door pocket 22 when the operation unit 78 is operated, the operator can recognize the gap between the sliding door 10 and the door pocket 22. It is possible to prevent the finger from being caught.

  Further, since the stopper 51 is biased to the first position P3 by the biasing spring 56, if the stopper 51 is in a position that does not overlap the anti-shake pin 26 in the vertical direction V, the stopper 51 is automatically It is positioned at the first position P3. For this reason, generation | occurrence | production of a finger | toe being pinched between the sliding door 10 and the door pocket 22 can be prevented further.

  Further, the guide portion 81 can smoothly move the stopper 51 along the vertical direction V with respect to the case 52 and the cover 53.

  Further, a gap S <b> 1 is provided between the end surface 88 exposed to the outside through the opening 79 of the case 52 and the inner surface 89 of the side wall 59 of the case 52 in the stopper 51. That is, since the inner surface 89 and the end surface 88 are not always in contact with each other, the end surface 88 is not rubbed against the inner surface 89 with the movement of the stopper 51, so that the end surface 88 is prevented from being damaged. For this reason, it can suppress that the external appearance of the sliding door 10 worsens.

  In addition, the stopper 51 and the anti-shake pin 26 that are in contact with each other in order to stop the sliding door 10 at the finger pinching prevention position P5 are housed in the housing groove 12, so that the parts that are in contact with each other are hidden from the outside. . The stopper 51 and the anti-shock pin 26 rub against each other when they come into contact with each other. However, as described above, the portions that rub against each other are not exposed when hidden from the outside, so that the appearance is poor. Can be suppressed. Furthermore, since the stopper 51 becomes difficult to see from the outside when the receiving groove 12 is opened at the lower end, it is possible to further suppress the appearance from deteriorating.

  Further, since the movement of the sliding door 10 is stopped by bringing the stopper 51 and the anti-shock pin 26 into contact with each other, the operation recess 18 can be brought into and out of contact with the tip of the door pocket 22 in order to stop the movement of the sliding door 10. There is no need to provide it. For this reason, when moving the sliding door 10 such as the operation concave portion 18, the design of the operation unit on which the operator attaches a finger can be freely selected.

  Further, the movement of the sliding door 10 is stopped by a structure in which the stopper 51 and the anti-shake pin 26 are brought into contact with each other, instead of a structure in which the operation part used by the operator when moving the sliding door 10 such as the operation recess 18 is brought into contact with the door pocket 22. Therefore, the movement of the sliding door 10 can be stopped regardless of the clearance between the sliding door 10 and the front wall portion 27 of the door pocket 22 and the clearance between the sliding door 10 and the rear wall portion 28 of the door pocket 22. .

  In the present embodiment, a biasing spring 56 is used. As another example, the biasing spring 56 may not be used. The relative relationship between the size of the boss portion 63 and the size of the through hole 64 reduces the friction between the boss portion 63 and the through hole 64 by providing a gap between the boss portion 63 and the through hole 64. The stopper 51 is set so that it can move smoothly. For this reason, the stopper 51 is automatically positioned at the first position P3 by its own weight. Note that, as in the present embodiment, by using the biasing spring 56, the stopper 51 can be more reliably positioned at the first position P3.

  Next, a finger pinching prevention device according to a second embodiment of the present invention will be described with reference to FIGS. In addition, the structure which has the same function as 1st Embodiment attaches | subjects the code | symbol same as 1st Embodiment, and abbreviate | omits description. In the present embodiment, the shape of the through hole 64 is different from that of the first embodiment. Further, the biasing spring 56 is not used. Other structures are the same as those in the first embodiment. The different points will be described.

  FIG. 8 is an exploded perspective view showing the stopper device 50 of the present embodiment. As shown in FIG. 8, in the present embodiment, the through hole 64 includes a holding protrusion 90 that holds the stopper 51 at the second position P4 or the first position P3. The holding protrusions 90 are provided on both surfaces of the inner surface of the through-hole 64 that face each other in the movement direction M, and protrude toward the other surface.

  The holding protrusion 90 is provided at an intermediate position in the vertical direction V of the through hole 64. In the through hole 64, spaces S <b> 2 and S <b> 3 in which the boss 63 can be accommodated are provided above and below the both protruding protrusions 90, respectively. A gap S4 is formed between the holding projections 90. The width of the gap S4 is smaller than the boss portion 63.

  On both sides of the stopper 51 that sandwich the through hole 64 in the moving direction M, a deformation groove 91 that can deform the edge of the through hole 64 is formed. By deforming the edge of the through-hole 64 to widen the gap S4, the boss 63 passes through the gap S4. At both upper ends of the edge portion 64 a of the through hole 64, a cut S <b> 5 that connects the deformation required groove portion 91 and the through hole 64 is formed. By forming the cut S5, the edge portion 64 is supported by the stopper 51 at the lower end portion, and is so-called cantilevered. The cut S5 is formed in order to make the holding force of the boss part 63 by the edge part 64a of the through hole 64 appropriate.

  FIG. 9 is a perspective view showing the sliding door 10 at the finger pinching prevention position P5 with a part of the vicinity of the stopper device 50 cut away. In FIG. 9, the cover 53 and the bracket 54 are omitted to clearly show the stopper 51, but actually, the cover 53 and the bracket 54 are used as in the first embodiment. Yes.

  As shown in FIG. 9, when the stopper 51 is in the first position P <b> 3 where the stopper 51 abuts against the anti-blur pin 26, the boss portion 63 is provided above the holding protrusion 90 in the through hole 64. It is accommodated in the space S2.

  FIG. 10 is a perspective view showing the state in which the stopper 51 is moved to the second position P4, as in FIG. As shown in FIG. 10, when the stopper 51 is moved to the second position P <b> 4, the boss portion 63 pushes up the gap S <b> 4 between the two holding projections 90 by pushing up the operation portion 78. As a result, the boss 63 passes through the gap S4, and therefore the stopper 51 can move upward.

  As shown in FIG. 10, when the stopper 51 moves to the second position P4, the boss portion 63 is accommodated in a space S3 formed below both holding projections 90 in the through hole 64. By holding the boss portion 63 in the space S3, the stopper 51 is held at the second position P4.

  When the stopper 51 is moved to a position where it comes into contact with the anti-shake pin 26 as shown in FIG. By pushing down the operation portion 78, the boss portion 63 pushes the gap S4 wide, so that the stopper 51 moves to the first position P3.

  In the present embodiment, since the stopper 51 is held at the first position P3 and the second position P4, the biasing spring 56 is not used. In the present embodiment, as described above, the stopper 51 is selectively held at the second position P4 and the first position P3 by the holding protrusion 90.

  In this embodiment, since the stopper 51 is held at the second position P4, the operator does not need to perform an operation such as continuing to push up the operation portion 78 to hold the stopper 51 at the second position P4. The sliding door 10 can be smoothly moved to the fully open position P2.

  The state where the stopper 51 is held at the second position P4 is a state where the finger pinching prevention device 40 does not function. The state where the stopper 51 is held at the first position P3 is a state where the finger pinching prevention device 40 functions.

  In this embodiment, the state where the function of the finger pinching prevention device 40 is stopped and the state where it functions can be selectively held. For this reason, for example, when a person such as a child who may pinch a finger between the sliding door 10 and the door pocket 22 operates the sliding door, the finger 51 is prevented from being pinched by always holding the stopper 51 at the first position P3. The device 40 can be in a functioning state. Then, when a person who is less likely to cause finger pinching, such as an adult, mainly operates the sliding door, the finger pinching prevention device 40 is disabled by holding the stopper 51 at the second position P4. 10 can be moved smoothly to the fully open position P2.

  Next, a finger pinching prevention device according to a third embodiment of the present invention will be described with reference to FIGS. In addition, the structure which has the same function as 1st Embodiment attaches | subjects the code | symbol same as 1st Embodiment, and abbreviate | omits description. In the present embodiment, the shape of the stopper 51 is different from that of the first embodiment. Other structures are the same as those in the first embodiment. The above different points will be specifically described.

  FIG. 11 is a plan view showing the vicinity of the stopper device 50 in a state where the sliding door 10 has reached the finger pinching prevention position P5. In FIG. 11, the cover 53 and the bracket 54 are not shown for easy understanding of the position of the stopper 51. However, in actuality, as in the first embodiment, the cover 53 and the bracket 54 are It is used.

  As shown in FIG. 11, an inclined surface 100 that is in contact with the anti-shake pin 26 and is inclined with respect to the vertical direction V is provided at the end of the stopper 51 in the moving direction M. The inclined surface 100 is inclined so as to extend upward from the middle part along the moving direction M of the lower end surface 51 a of the stopper 51 toward the other end side in the moving direction M. The inclined surface 100 is a flat surface. When the sliding door 10 reaches the finger pinching prevention position P5, the inclined surface 100 comes into contact with the anti-shake pin 26.

  As shown in FIG. 11, when the sliding door 10 is further pushed into the door pocket 22 from a state in which the inclined surface 100 abuts against the anti-shake pin 26, the anti-shake pin 26 moves on the inclined surface 100 with respect to the inclined surface 100. To slip. As the anti-shake pin 26 slides on the inclined surface 100, the stopper 51 moves upward and moves above the anti-shake pin 26.

  FIG. 12 is a front view showing the state in which the stopper 51 gets over the anti-shake pin 26 as the anti-shake pin 26 slides on the inclined surface 100, as in FIG. As shown in FIG. 12, when the stopper 51 gets over the anti-shake pin 26, the operator can move the sliding door 10 to the fully open position P2 without operating the operation portion 78. In the present embodiment, the second position P4 is set such that a gap is formed between the lower end surface 51a of the stopper 51 at the second position P4 and the anti-shake pin 26. As shown in FIG. 12, the lower end surface 51 a of the stopper 51 is in contact with the anti-shake pin 26 when the stopper 51 gets over the anti-shake pin 26 as the sliding door 10 moves. For this reason, the stopper shown in FIG. 12 is located below the second position P4.

  As shown in FIGS. 11 and 12, the stopper 51 may include an operation unit 78. As in the first embodiment, the sliding door 10 can be moved to the fully open position P2 by operating the operating portion 78 and moving the stopper 51 above the anti-shake pin 26. Alternatively, the operation unit 78 may not be provided.

  Next, operation | movement of the finger pinching prevention apparatus 40 of this embodiment is demonstrated. When the operator moves the sliding door 10 from the fully closed position P1 toward the fully open position P2, the inclined surface 100 of the stopper 51 contacts the anti-shake pin 26 at the finger pinching prevention position P5 as shown in FIG.

  Since the force required to move the sliding door 10 increases when the anti-shake pin 26 comes into contact with the inclined surface 100, the movement of the sliding door 10 is temporarily stopped. When the movement of the sliding door 10 is stopped, the operator moves the sliding door 10 toward the fully open position P <b> 2 with a force greater than that at the beginning so that the stopper 51 can get over the anti-shake pin 26.

  When the force over which the stopper 51 gets over the anti-spin pin 26 is input to the sliding door 10, the stopper 51 gets over the anti-spin pin 26 as shown in FIG. 12, so that the sliding door 10 moves to the fully open position P2.

  In the present embodiment, the anti-shake pin 26 includes a sphere portion 26b, and has a shape in which the upper end portion is a sphere. In another example, instead of the anti-blur pin 26, a protrusion having an inclined surface that comes into surface contact with the inclined surface 100 may be used. This protrusion has a function of positioning the sliding door 10 at the center in the width direction of the sill groove 24 of the sill 23, which is a function of the anti-shake pin 26.

  In this case, the inclined surface 100 of the stopper 51 and the inclined surface of the protruding portion are in surface contact with each other, so that the stopper 51 can easily get over the protruding portion. For this reason, the sliding door 10 can be smoothly moved to the fully open position P2.

  In the present embodiment, the stopper 51 has the inclined surface 100 as an example for moving the sliding door 10 so that the stopper 51 can get over the anti-shake pin 26 without operating the operation portion 78. The inclined surface 100 is a flat surface. As another example, the inclined surface 100 may be a curved surface instead of a flat surface.

  In short, when the stopper 51 reaches the finger pinching prevention position P5, the climbing portion that gets over the protruding portion with the operation of pulling the sliding door 10 at the portion that contacts the protruding portion (in this embodiment, the anti-shake pin 26 as an example). Should just be provided. The inclined surface is an example of a climbing part.

  Next, a finger pinching prevention device according to a fourth embodiment of the present invention will be described with reference to FIG. In addition, the structure which has the same function as 1st Embodiment attaches | subjects the code | symbol same as 1st Embodiment, and abbreviate | omits description. In this embodiment, it replaces with the door pocket 22 and the point by which the wall part 110 is used differs with respect to 1st Embodiment. Other structures are the same as those in the first embodiment. The above different points will be specifically described.

  FIG. 13 is a perspective view showing the sliding door 10 provided with the finger pinching prevention device 40 of the present embodiment and a part thereof in the vicinity thereof. As shown in FIG. 13, in this embodiment, the wall part 110 is provided. In the present embodiment, the opening 20 is formed between the wall 21 and the wall 110.

  The wall portion 110 is formed with a recess 111 for accommodating the sliding door 10 moved to the fully open position P2. The sliding door 10 is accommodated in the recess 111 as it moves. When an operator moves the sliding door 10 from the rear surface 14 side to the fully open position P2 using the operation recess 18 formed on the rear surface 14 of the sliding door 10, there is a possibility that a finger may be caught between the wall 110 and the sliding door 10. is there.

  In the present embodiment, the finger pinching prevention position P5 is set to a position where the end surface 112 of the wall portion 110 on the opening 20 side and the edge 18a on the other end side in the movement direction M in the operation concave portion 18 overlap in the front-rear direction. ing. Even in the present embodiment, the same effect as in the first embodiment can be obtained.

The operation recesses 18 formed on the front surface 13 and the rear surface 14 are arranged at positions overlapping in the front-rear direction. The operating recess 18 of the sliding door 121 is provided at one end of each of the front surface 13 and the rear surface 14 in the moving direction M. The operation recesses 18 formed on the front surface 13 and the rear surface 14 are arranged at positions overlapping in the front-rear direction.

  FIG. 14 shows a state in which one sliding door 120 is in the fully closed position P1 and the other sliding door 121 is in the fully open position P2. Here, in the sliding doors 120 and 121, each fully closed position P1 and each fully open position P2 are demonstrated concretely.

  As shown in FIG. 14, in the present embodiment, the opening 20 is formed by a sill 23, a duck 30, and side wall parts 122 and 123 provided at both ends in the moving direction M of the sill 23 and the duck 30. The side wall parts 122 and 123 are connected to the threshold 23 and the duck 30.

  The fully closed position P <b> 1 of the sliding door 120 is a position where the sliding door 120 comes into contact with the other side wall portion 123. The fully closed position P <b> 1 of the sliding door 121 is a position where the sliding door 121 comes into contact with one side wall portion 122. When the sliding doors 120 and 121 are in the fully closed position P1, the opening 20 is closed.

  The fully open position P <b> 2 of the sliding door 120 is a position in contact with the side wall portion 122. The fully open position P <b> 2 of the sliding door 121 is a position in contact with the side wall portion 123. If one of the sliding doors 120, 121 is in the fully closed position P1, and the other is in the fully open position P2, the range to be covered by the other sliding door in the opening 20 is in the fully open state.
