Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a device for preventing repulsion of a sliding door.
[0002]
[Prior art]
  Sliding doors are widely installed in residential facilities. However, when the sliding door is closed vigorously, the end surface of the sliding door collides with the door frame, the sliding door repels and a gap is formed between the door frame.
[0003]
  Therefore, measures are taken to provide an obstacle on the track side so that the sliding door decelerates immediately before the sliding door closes. That is, a leaf spring is provided at the end portion of the track (the duck or the sill), and when the sliding door is about to close, the leaf spring is brought into contact with a part of the sliding door to decelerate the sliding door. That is, when the sliding door is close to closing, the sliding door is braked by the leaf spring.
[0004]
[Problems to be solved by the invention]
  As described above, as a countermeasure against repulsion when the sliding door is closed, a measure for attaching a leaf spring to the track is known. However, it has been difficult for the prior art measure to brake the sliding door with an appropriate strength. For this reason, there is a problem that the sliding door stops halfway without being completely closed, and conversely, the sliding door is repelled due to insufficient braking.
[0005]
  Accordingly, the present invention focuses on the above-mentioned problems of the prior art, and an object of the present invention is to develop a sliding door repulsion prevention device capable of reducing the sliding door to an appropriate speed and adjusting it.
[0006]
[Means for Solving the Problems]
  And to solve the above-mentioned problemsThe invention is as follows.
  Claim 1The sliding door repulsion prevention device according to claim 1 has a protrusion portion attached to the track side, a main body portion, the main body portion having a main body case having two or more release surfaces, and a slide made of elastic band. A moving path and adjusting means, wherein the sliding path is inside the main body case and has a tapered portion, and a fitting portion is provided at the end of the sliding path to which the protruding portion is fitted. Has a slider that moves linearly with a screw, the slider is in contact with a part of the band that forms the sliding path in the main body, and the width of the sliding path increases or decreases according to the movement of the slider. The sliding door repulsion prevention device is characterized in that the engaging portion of the screw with the tool is located at the end of the main body.
[0007]
  In the sliding door repulsion prevention device of the present invention, the protrusion is attached to the track side, and the sliding path is attached to the sliding door side. In the sliding door repulsion prevention device of the present invention, when the sliding door is closed, the projection enters the sliding path, but the sliding path is urged in the narrowing direction by the elastic body, so the projection is the sliding path. Friction occurs between the protruding portion and the sliding portion when passing through. Therefore, the brake is applied to the sliding door to which the sliding path is attached. In addition, the sliding door repulsion prevention apparatus of the present invention has adjusting means for changing the width of the sliding portion, so that the strength of the brake can be adjusted.
[0008]
  Furthermore, in the sliding door repulsion prevention device of the present invention, since the fitting portion is provided at the end of the sliding path, when the sliding door is in a closed state, the projection portion is fitted with the fitting portion to resist the repulsive force. And keep it closed. In the sliding door repulsion prevention apparatus of the present invention, the sliding path is constituted by an elastic band, and the sliding path is urged in the narrowing direction by the elasticity of the band itself. Therefore, the repulsion prevention apparatus for sliding doors of the present invention has a small number of parts and is easy to make. In the sliding door repulsion prevention apparatus of the present invention, the sliding path is provided with a tapered portion. Therefore, the brake applied to the sliding door can be gradually strengthened.
[0009]
  Further, in the sliding door repulsion prevention device of the present invention, the width of the sliding path can be adjusted by rotating the screw, and the engaging portion of the screw with the tool is located at the end of the sliding door. The braking force can be adjusted without removing the sliding door from the track.

The width of the sliding path is increased or decreased by1It is a sliding door repulsion prevention apparatus of description.
[0013]
  In the sliding door repulsion prevention apparatus of the present invention, when the slider moves, the band abutted against the slider bends in the width direction by the pressing force applied in the longitudinal direction, and the width of the sliding path can be adjusted by increasing or decreasing the bending. When the slider is at the farthest position from the taper, no pressing force is applied to the band, and therefore the width of the sliding path is maximized before the band is deformed. The method is simple in structure and easy to operate.2Unlike the above method, the band does not rub against the slit, and the durability is better.
[0014]
  Further claims42. The sliding door repulsion prevention apparatus according to claim 1, further comprising movement adjusting means for translating the sliding path in the width direction of the track.OrClaim2The sliding door repulsion prevention device described in 1.
[0015]
  In the sliding door repulsion prevention device of the present invention, when the initial manufacturing error and the displacement due to the continued use are too large, the displacement in the width direction between the track and the sliding door is too large, so it is not possible to cope with only by adjusting the width of the sliding path. The brake strength applied to the sliding door can be appropriately adjusted by adjusting the displacement by moving the sliding path in the width direction of the track by the movement adjusting means.

[0022]
  1 and 5, 1 is a duck (track), and 2 is a sliding door. Reference numeral 30 denotes a sliding door repulsion prevention apparatus according to an embodiment of the present invention. The sliding door repulsion prevention device 30 according to the present embodiment is roughly constituted by the head member 31 and the main body 4.
[0023]
  The head member 31 has a plate-like member 32 as shown in FIG. 2, and the protrusion 3 is provided on one surface thereof. The shape of the protrusion 3 is a substantially pentagonal columnar shape. That is, the planar cross section of the protrusion 3 is substantially pentagonal, one end 3a is sharp, and the other end 3b is a flat surface. Further, the height of the protrusion 3 is smaller than the height inside the box 10 of the main body 4 described later. The protrusion 3 is provided in the vicinity of the end of the plate-like member 32, and the sharp side 3 a faces the outside of the plate-like member 32. 1 and 2, the protrusion 3 is provided at the left end of the plate-like member 32, the pointed side 3a faces the left outer side, and the flat end 3b faces the inner side. . The head member 31 is attached to the inside of the groove of the upper head 1 to which the sliding door 2 is attached as shown in FIG. 1, and the protrusion 3 is located on the lower side. Further, the Kamoi side member 31 is located at the end of the groove of the Kamoi 1, and the end of the plate-like member 32 coincides with the end of the Kamoi groove.
[0024]
  The pointed side 3a of the protrusion 3 is attached to the inside of the duck 1 as shown in FIGS. Moreover, since the edge part of the plate-shaped member 32 is made to correspond with the edge part of a Kamoi groove as mentioned above, the distance from the edge part of the Kamoi groove of the projection part 3 becomes fixed. That is, the plate-like member 32 of the head member 31 exhibits a function of easily and reliably attaching the protrusion 3 to the head 1 and a function of positioning the protrusion 3.
[0025]
  On the other hand, the main body 4 is constituted by a box 10, a band 5, and a slide adjustment unit 14. The slide adjusting unit 14 is further configured by an adjusting screw 16 and a slider 11. This will be sequentially described below.
[0026]
  The box body 10 is a combination of two large and small boxes 35 and 36, and the entire length thereof is equal to the above-described Kamoi side member 31. The width will be described laterInterviewShorter than case 70. Of the two boxes 35 and 36 described above, the larger box 35 is a band arrangement box and has a rectangular parallelepiped shape in which the upper surface 10a and one side surface 10b are opened. In the vicinity of the side surface 10b on the open side of the band arrangement box 35, the inner width is wider than that of the other portions, and the slide adjusting portion 14 is formed. A protrusion 10d is provided on the bottom plate in the vicinity of the side surface 10c on the closing side of the band arrangement box 35. On the other hand, the small box 36 is an adjustment screw arrangement box, and is provided on the bottom side of the above-described band arrangement box 35. The adjustment screw arrangement box 36 is located at the open end of the band arrangement box 35, and the side surfaces of the two boxes 35 and 36 are in the same plane.
[0027]
  The band arrangement box 35 and the adjustment screw arrangement box 36 communicate with each other as shown in FIG. Support holes 18a and 18b are provided at both ends of the adjustment screw arrangement box 36 as shown in FIG. An adjustment screw 16 is inserted through the support holes 18a and 18b. The adjustment screw 16 is attached to the adjustment screw arrangement box 36 so as not to move in the axial direction by an engaging portion (not shown). Therefore, the adjusting screw 16 rotates on the spot and does not move in the axial direction. Further, the engagement portion 37 of the screw with the tool is exposed on the end face of the adjustment screw arrangement box 36 as shown in FIGS.
[0028]
  The band 5 is a thin steel plate having elasticity, and is formed by bending a single steel sheet. The shape of the band 5 is as shown in FIGS. 1 and 3, and is folded back from the center in the form of a hairpin, and a sliding path 38 is formed by the respective inner surfaces. That is, in the band 5, the steel plate is folded back from the center portion, and the pair of steel plates 5a and 5b are opposed to each other. The pair of steel plates 5a and 5b are open at one end and closed at the other end. There is a gap between the steel plates 5 a and 5 b, and this gap functions as the sliding path 38. Referring to FIGS. 1 and 2, the left end of the drawing is closed, the right portion is open, and a series of passages from the open end of the right end to the closed portion of the left end is formed.
[0029]
  The shape of the sliding path 38 is roughly divided into four parts as shown in FIG. That is. The sliding path 38 formed by the band 5 is functionally composed of a fitting port portion 6, an elasticity adjusting portion 7, a guide portion (tapered portion) 8, and a fitting portion 9.OneIt is divided into parts. Here, the fitting opening 6 has two opposing steel plates 5a and 5b positioned substantially in parallel. The gap of the band 5 at the fitting opening 6 is larger than the width of the protrusion 3.
[0030]
  In the elasticity adjusting portion 7, the two opposing steel plates 5a and 5b are provided with a taper of about 30 °. Further, the band 5 passes through a slit 12 of a slider 11 described later in the elasticity adjusting unit 7.
[0031]
  The guide portion (taper portion) 8 is a portion where a taper having a smaller angle than the above-described elasticity adjusting portion 7 is formed. In this embodiment, the distance between the ends of the guide portion 8 is narrowed little by little so that the opening interval is smaller than the width of the protruding portion 3. The total length of the guide portion (tapered portion) 8 is the longest of the four portions of the fitting port portion 6, the elasticity adjusting portion 7, the guide portion (tapered portion) 8, and the fitting portion 9, and is about 40 mm to 80 mm. .
[0032]
  The fitting portion 9 is located at the end of the guide portion 8 and is a portion where the width of the two steel plates 5a and 5b is suddenly widened. In the fitting portion 9, the opening interval is widened so as to be larger than the width of the projection portion 3, and the fitting portion 9 is closed at the left end. Of the fitting part 9DirectionThis length is longer than the length of the projection 3, and is therefore designed to have a dimension that allows the projection 3 to be fitted and accommodated in the fitting portion 9. As shown in FIG. 3, the slider 11 constituting the slide adjusting portion 14 is configured by a sliding portion 11a having a substantially “U” shape and a support plate 13 provided on the back surface of the sliding portion 11a. . That is, the sliding part 11a has two side surfaces and a bottom surface, and the other surfaces are released. And the slit 12 is provided in two side surfaces. On the other hand, the support plate 13 is a wall body erected perpendicularly to the bottom plate of the sliding portion 11a, and has a screw hole 15 in the center.
[0033]
  The above-described band 5 is arranged in the band arrangement box 35 so that the fitting portion 9 is on the back side with respect to the opening end surface. Further, the folded portion of the band 5 is sandwiched between the inner wall on the back side of the band arrangement box 35 and the protrusion 10 d, and the band 5 does not fall out of the band arrangement box 35. In particular, since the folded portion of the band 5 and the protrusion 10d are engaged, the movement of the band 5 in the longitudinal direction is prevented. When the band 5 is arranged in the band arrangement box 35, the distance from the side surface 10 b on the open side of the band arrangement box 35 to the fitting part 9 is from the end of the above-described Kamoi side member 31 to the protruding part. It is equal to the distance up to 3.
[0034]
  The slider 11 is disposed in the slide adjusting portion 14 of the band arranging box 35 in the “co” state where the substantially “ko” -shaped open side is opened upward. The support plate 13 of the slider 11 protrudes into an adjustment screw arrangement box 36 provided on the lower outer side of the box 10. That is, the inside of the adjustment screw arrangement box 36 is a rectangular parallelepiped small chamber, and the support plate 13 is disposed in the small chamber.
[0035]
  As described above, the support screw holes 18a and 18b are provided at both ends of the adjustment screw arrangement box 36, the adjustment screw 16 is provided inside, and the adjustment screw 16 is supported by the support holes 18a and 18b. It can be rotated. The adjustment screw 16 holds the support plate 13 by passing through the screw hole 15 of the support plate 13 of the slider 11. A screw portion 17 is provided on the outer periphery of the center portion of the adjustment screw 16, and the screw portion 17 is screw-engaged with the screw hole 15 of the support plate 13. As described above, since the adjusting screw 16 does not move in the axial direction, when the engaging portion 37 with the tool exposed at the end portion is rotated, the support plate 13 that engages with the screw portion 17 moves in the axial direction. . Accordingly, when the adjusting screw 16 is rotated, the sliding portion 11a of the slider 11 is linearly moved in the axial direction by the band arranging box 35.
[0036]
  As described above, the slits 12 are provided on both side surfaces of the slider 11, and the elasticity adjusting portion 7 of the band 5 passes through the slit 12, and the fitting opening 6 extends from the outside of the slider 11 to the band arranging box 35. It is assembled in a state extending to the open end side.
[0037]
  The Kamoi side member 31 demonstrated above is attached to the upper corner | angular part of the sliding door 2 like FIG. Further, when mounting the head member 31, consideration is given so that the end surface of the head member 31 is flush with the end surface of the sliding door 2.
[0038]
  The situation when the sliding door 2 having the above structure is closed will be described with reference to FIG. When the sliding door 2 is closed, the main body portion 4 moves together with the sliding door 2 in the right direction in FIG. 5, and the main body portion 4 approaches the protrusion 3 on the Kamoi 1 side. Here, since the upper surface 10 a and the side surface 10 b of the band arrangement box 35 of the main body portion 4 are opened, the protruding portion 3 suspended from the upper head 1 can enter the main body portion 4. As the sliding door 2 moves, the fitting port 6 of the band 5 is first put on the protrusion 3 (see FIG. 5a).
[0039]
  Further, the movement in the right direction continues, and the guide portion 8 hangs on the projection portion 3 through the elasticity adjusting portion 7 (see FIG. 5b). In the guide portion 8, since the band 5 has elasticity, the guide portion 8 is pushed and expanded to the projection portion 3, and the main body portion 4, the sliding door 2, and the guide portion 8 sandwich the projection portion 3. The one-piece movement continues. At this time, the sliding path 38 of the guide portion 8 is urged in the narrowing direction by the elasticity of the band 5 itself, so that a frictional force due to the elastic pressure is generated between the guide portion 8 and the protruding portion 3. The sliding door 2 continues to move to the right in the drawing while being forcibly decelerated. The guide portion 8 is tapered, and the width of the sliding path 38 becomes narrower toward the back, and a stronger braking force works as the sliding door 2 approaches the end of the duck 1.
[0040]
  When the sliding door 2 is in a closed state, the fitting portion 9 is hung on the protruding portion 3, and finally the protruding portion 3 is fitted in the fitting portion 9, and the sliding door 2 is moved. It is stopped (see FIG. 5c).
[0041]
  Moreover, since the connection part of the fitting part 9 and the guide part 8 is narrow, the projection part 3 once fitted in the fitting part 9 is hard to escape from the fitting part 9. That is, when the protruding portion 3 reaches the fitting portion 9 as the sliding door 2 moves, the protruding portion 3 hardly moves to the guide portion 8. Therefore, even if the sliding door 2 hits the door frame side vigorously, the sliding portion 3 is fitted with the fitting portion 9, so that the sliding door does not repel and remains closed. Thus, if the degree of relaxation of the impact between the end face of the sliding door 2 and the pillar / wall is sufficiently safe and the sliding door 2 can be opened and closed smoothly, it can be used as it is. On the other hand, if the degree of relaxation of the impact between the end face of the sliding door 2 and the pillar / wall when the sliding door 2 is closed is not sufficiently safe, or if the sliding door 2 is not opened and closed smoothly, the following adjustment is performed. First, the adjusting screw 16 of the slide adjusting unit 14 is rotated using a screwdriver or the like. Here, in the sliding door repulsion prevention device 30 of the present embodiment, since the engaging portion 37 with the screwdriver of the adjustment screw 16 is exposed on the end surface of the sliding door 2, the adjustment screw 16 can be easily rotated. . That is, the adjusting screw 16 can be rotated without removing the sliding door 2.
[0042]
  When the adjustment screw 16 rotates, the support plate 13 screwed to the screw portion 17 of the adjustment screw 16 moves in the horizontal direction, and the slider 11 moves linearly in the horizontal direction together with the support plate 13. When the slider 11 moves in the axial direction, the contact position between the slit 12 provided in the sliding portion 11a of the slider 11 and the band 5 changes.
[0043]
  On the other hand, since the elasticity adjusting portion 7 that is a portion that contacts the slit 12 of the band 5 is provided with a taper, the opening side of the band 5 is narrowed or loosened according to the movement of the slider 11. Therefore, the interval of the band 5 is changed by rotating the adjusting screw 16 and moving the slider 11. For example, when the adjusting screw 16 is rotated from the state of FIG. 4A and the slider 11 is moved to the opening side (right side of the drawing), the opening interval of the guide portion 8 of the band 5 is as shown in FIG. Since the frictional force due to the pressure that is narrowed and the protrusion 3 when the sliding door 2 is closed is sandwiched between the guide portions 8 increases, the impact between the end surface of the sliding door 2 and the pillar / wall is weakened.
[0044]
  On the contrary, when the slider 11 moves to the left, the opening interval of the guide portion 8 of the band 5 is widened, and the friction caused by the pressure at which the projection portion 3 is closed by the guide portion 8 of the band 5 when the sliding door 2 is closed. Since the force is reduced, the sliding door 2 is opened and closed more smoothly than before the adjustment, but the impact between the sliding door end face and the pillar / wall when closed is stronger than before the adjustment. Therefore, before the first use of the sliding door 2 of the present invention, after the sliding door 2 is closed, the sliding door 2 is closed when the sliding door 2 is closed by repeating the opening and closing of the sliding door 2 and the adjustment of the adjusting screw 16 as described above. It is desirable to appropriately adjust the degree of impact between the end face of the door and the pillar / wall and the smoothness when the sliding door 2 is opened and closed. In the embodiment described above, the sliding path 38 is made of an elastic band. However, for example, the sliding path 38 is made of a resin having excellent slidability, and the resin is made of an elastic body such as a spring or rubber. The stenosis direction may be urged.
[0045]
  In the embodiment described above, the sliding door repulsion prevention device is attached to the upper portion of the sliding door 2, but it may be attached to the lower portion, that is, the sill side.
[0046]
(Embodiment 2)
  Hereinafter, a second embodiment of the present invention will be described. FIG. 7 is a perspective view of the repulsion prevention device according to the second embodiment of the present invention as seen from above. FIG. 8 is a perspective view of the sliding door repulsion prevention device (not including the movement adjustment unit) of the present invention as seen from the lower side. FIG. 9 is a perspective view of a band and a slider of the sliding door repulsion prevention device of FIG. 10 is a cross-sectional view taken along line AA in FIG. 7 (a) and a cross-sectional view taken along line BB (b). 11 is a cross-sectional view taken along the line CC in FIG. 7 for explaining the operation when the slider of the sliding door repulsion prevention apparatus is moved.
[0047]
  In the following, the same members as those in the first embodiment will be described with the same reference numerals. 7 to 11, 1 is a duck (track), and 2 is a sliding door. Reference numeral 50 denotes a sliding door repulsion prevention apparatus according to an embodiment of the present invention. The sliding door repulsion prevention device 50 according to the present embodiment is roughly configured by the head member 31 and the main body 4.
[0048]
  While the structure of the head member 31 and how to attach it to the head (track) 1 is the same as that of the first embodiment, the main part 4 is composed of a box 10 and a band 5 as shown in FIGS. Although it is the same as that of Embodiment 1 mentioned above by the point which has the slide adjustment | control part 14, in this Embodiment, the junction part 48 for movement is further added. This will be sequentially described below.
[0049]
  As shown in FIGS. 8 and 10, the box 10 has a band arrangement box 35, and its main body is the same as that of the first embodiment, but is molded integrally with the box 10 instead of the adjustment screw box. The screw base 45 is provided on the bottom surface of the box body 10 on the sliding door end side. Grooves 46 a and 46 b are provided on the bottom surface of the screw base 45. The groove 46a passes through the longitudinal center line of the screw base 45 to both ends of the screw base 45, and the groove 46b is near the end on the sliding door end side and is orthogonal to the groove 46a. The adjusting screw 16 is rotatably accommodated in the groove 46a. A C ring 47 is attached between the screw portion of the adjustment screw 16 and the screw head 16a, and the C ring 47 is forcibly fitted into the groove 46b. As a result, the adjusting screw 16 is supported by the groove 46b via the C ring 47 and can rotate in the groove 46a, but is restricted by the C ring 47 and prevented from moving in the axial direction.
[0050]
  The band 5 is substantially the same as that of the first embodiment, and is formed by bending a thin strip of steel having elasticity into a hairpin shape, and the inner surface of the hairpin forms a sliding path 38.
[0051]
  The sliding path 38 is divided into four parts as shown in FIG. 11 that function in the same manner as in the first embodiment. That is, there are four portions, that is, the fitting port portion 6, the elasticity adjusting portion 7, the guide portion (taper portion) 8, and the fitting portion 9. However, the configuration of the elasticity adjusting portion 7 is different from that of the first embodiment, and the band 5 is a contact portion 7a in which the end portion on the guide portion 8 side is bent in an L shape outwardly as shown in FIG. 7a is contacted with an end 11b of a slider 11, which will be described later, and the elasticity of the band is adjusted. The band 5 is bent into an L shape from the abutting portion 7 a, and the elasticity adjusting portion 7 ends at a point where it comes out of the end portion 11 b of the slider 11, and reaches the fitting opening 6. Therefore, in the second embodiment, the elasticity adjusting portion 7 is in a very narrow range including the abutting portion 7a. The external shape of the slider 11 constituting the slide adjusting unit 14 is similar to that of the first embodiment. As shown in FIG. 9, the slider 11a having a substantially “U” shape and the bottom surface of the slider 11a are formed. It is comprised by the support plate 13 provided in the downward direction of the edge part by the side of the guide part 8. FIG. That is, the sliding part 11a has a bottom surface and two side surfaces, and the other surfaces are released. The support plate 13 is a wall body erected perpendicularly to the bottom plate of the sliding portion 11a, and has a screw hole 15 in the center. However, in the present embodiment, the sliding portion 11a is a simple plate having no slit.
[0052]
  The slider 11 is arranged in the elasticity adjusting portion 7 of the band 5 in the box 10 with the sliding portion 11 a in the “U” state with the substantially “U” -shaped open side upward. The support plate 13 of the slider 11 protrudes downward and comes into contact with the end face of the screw base 45 provided on the lower outer side of the box body 10 on the side opposite to the sliding door end, so that the screw hole 15 and the adjusting screw 16 are engaged. Is supported by the adjusting screw 16.
[0053]
  As described above, the adjusting screw 16 is housed in the groove 46a of the screw base 45, is supported by the groove 46b via the C ring 47, and can rotate while being prevented from moving in the axial direction. Therefore, when the adjustment screw 16 is rotated, the support plate 13 of the slider 11 engaged with the screw portion 17 moves in the axial direction, and the sliding portion 11a moves linearly in the axial direction in the box body 10.
[0054]
  A method for adjusting the elasticity of the band 5 by the slider 11 according to the present embodiment will be described with reference to FIG. First, the adjusting screw 16 of the slide adjusting unit 14 is rotated by using a screwdriver or the like. When the adjusting screw 16 rotates, the support plate 13 screwed to the screw portion 17 of the adjusting screw 16 moves in the axial direction, and the support plate 13 and the slider 11 move linearly in the axial direction. When the slider 11 moves in the axial direction, a pressing stress is applied to the contact portion 7a of the elasticity adjusting portion 7 of the band 5 that is in contact with the end portion 11b of the sliding portion 11a of the slider 11, and the guide portion of the band 5 is moved. 8 is bent inward. Therefore, the interval of the band 5 is changed by rotating the adjusting screw 16 and moving the slider 11. For example, when the adjusting screw 16 is rotated from the state of FIG. 11A to move the slider 11 to the opening side (right side of the drawing), the opening interval of the guide portion 8 of the band 5 is as shown in FIG. Since the frictional force between the projection 3 and the guide 8 when the sliding door 2 is closed is increased, the impact between the end surface of the sliding door 2 and the pillar / wall is weakened. When the adjusting screw 16 is rotated from the state of FIG. 11B and the slider 11 is moved to the side opposite to the opening (left side of the drawing), the guide portion 8 of the band 5 is opened as shown in FIG. The space is widened, and the frictional force between the projection 3 and the guide 8 when the sliding door 2 is closed is reduced, so that the impact between the end surface of the sliding door 2 and the pillar / wall is strengthened.
