JP 2001-132335 A

  However, there are cases where it is desired to give various decorations to the door surface of the sliding door. In that decoration, the door surface is made to protrude partially from the original door surface, that is, the basic door surface, or a separate decorative member. To make it protrude from the basic door surface. Even with such protrusions, the sliding door needs to pass in front of the vertical, so that the front end position of the vertical is inevitably retracted to the vertical side than when the sliding door has no protrusion. As a result, the vertical side basic door surface located on the door bottom side of the fully closed sliding door is separated from the longitudinal airtight member provided in the vertical direction.

  However, since the airtight member is an elastic member, if the size is made to project greatly forward (door surface side), the sliding door can be passed while being elastically deformed even when the sliding door is opened. It is thought that it can contact | abut to the vertical side door surface of a sliding door. However, the elastic member protruding greatly in this way maintains a long dimension contact state from the vicinity of the upper end of the sliding door to the vicinity of the lower end thereof, and it is difficult to maintain airtightness, and also looks good. Absent. Even if the sliding door is not provided with a protruding decorative part at the beginning of construction, for example, it may be desired to provide it at the time of renovation. In such a case, if there is no substantial gap between the basic door surface of the sliding door and the vertical, not only the installation work of the decorative parts, but also the frame of the entrance / exit structure must be replaced. It is not provided. Furthermore, when opening and closing the sliding door, there is no problem when operating with the handle on the door end side, but there may be a case where the user tries to open and close with the hand on the door bottom side. In such a case, the finger of the attached hand may be caught between the sliding door and the vertical wall, causing unexpected injury.

  Therefore, the problem to be solved is that when a projecting part such as a decorative part is provided, there is no hindrance to opening and closing the sliding door, and when such a projecting part is not provided, a finger is placed between the sliding door and the vertical. An object of the present invention is to provide an airtight structure of a sliding door that can maintain airtightness when the sliding door is fully closed, while presupposing that it can be prevented from being injured.

  Hereinafter, the present invention will be described in detail with reference to the drawings. 1 is a top view of a sliding door mechanism section according to the present invention in a cross-sectional view, FIG. 2 is a longitudinal sectional view taken along line BB in FIG. 1, and FIG. 3 is a front view of the sliding door mechanism section. 4 is an enlarged view near the vertical direction of FIG. 1, FIG. 5 is a perspective view of some parts viewed from the direction of arrow E in FIG. 4, and FIG. 6 is a schematic plan view of the lower frame in FIG. A framework of the entire sliding door mechanism section that separates the room R and the outside O and moves the sliding door 10 in the left-right direction to open and close the entrance / exit will be described. Note that the room R and the outside O shown in FIG. 1 may be reversed.

  The door end side vertical frame 30 that extends in the vertical direction and is positioned on one end side in the left and right direction, the door bottom side vertical frame 32 that is positioned on the other end side, and the horizontal direction that connects the upper ends of these vertical frames And a lower frame 38 that connects the lower ends and extends in the left-right direction. Furthermore, there is a stand 34 extending in the vertical direction at an intermediate position between the left and right vertical frames. The space between this vertical and the vertical frame 30 is an entrance. FIG. 6 is a view for showing a schematic outline of the huller 38, and other members, that is, the door-end side vertical frame 30, the door-end side vertical frame 32, and the vertical frame 34 are also schematic views. It only shows the relative positional relationship.

  The huller 38 has a high-side flat portion 38A on which a rectangular portion of a vertical portion 34 described later is placed, and a low-planar portion 38B that is one step lower than the high-planar portion. . In this example, the high flat surface portion 38A side is the room R side. I will explain a little more about the positional relationship between the hail and the vertical. At the position of a door-end-side surface 34A, which will be described later, forming one side of the rectangular portion, the width of the high flat portion 38A of the hull is changed in a step shape. The end 38E of the hull at this position is referred to as the vertical end of the hull (lower frame). Although not shown, the end of the upper frame 36 at the same position is referred to as the vertical end of the upper frame. Further, the other side 34B, which will be described later, adjacent to the one side 34A is located at the edge of the narrow region of the high plane part.

  The sliding door 10 here is a suspension system, and rollers 14A and 14B are provided at the upper end of the sliding door so as to roll along the rail 12 attached to the upper frame 36. Further, a piston / cylinder mechanism 16 is attached to the upper frame as an air compression type attenuator. Moreover, the member 18 which has the magnet 18J at the front-end | tip is attached to the sliding door upper end part, and this magnet is connected with the outer end part of the said piston by magnetic force in the fully closed state of a sliding door. Furthermore, a coil spring is built in the upper end of the sliding door, and a winding device 20 for winding the wire 22 is attached. On the other hand, the outer end portion of the wire 22 is locked to the upper frame or an appropriate portion integral therewith.

  Therefore, when the handle 11 is put on the handle 11 and the door bottom side of the sliding door 10 is moved in the direction approaching the vertical frame 32, the member 18 moves with the sliding door while pulling out the piston of the piston / cylinder mechanism 16. At this time, the wire 22 is pulled out from the winding device 20 while receiving tension, and accordingly, the spring force is accumulated in the built-in coil spring. When the sliding door moves halfway, the piston is pulled out and stopped, and the tip magnet of the member 18 moves away from the piston. On the other hand, a locking member 24 is attached to the upper end door bottom of the sliding door 10, and a leaf spring member 26 capable of locking the locking member is attached near the vertical frame 32 of the upper frame 36.

  Thus, when the sliding door is moved so that the doorway is in the fully open state, it is possible to restrict the sliding door from moving in the fully closed state due to the engagement of the locking member 24 and the leaf spring member 26, and the fully open state can be maintained. . Once the sliding door handle 11 is pulled lightly to release the engagement to bring the doorway into the fully closed state, the sliding door is closed while pulling the wire 22 by the spring force accumulated in the winding device 20. Can move automatically in the direction. In the middle of the movement, the tip magnet portion of the member 18 begins to press the cylinder, and from this stage, the sliding door movement is attenuated by the damping action of the piston / cylinder mechanism, and the door end side of the sliding door collides with the vertical frame 30. Prevents and closes quietly.

In the present invention, the moving mechanism of the sliding door described above is merely an example, and various known mechanisms such as an electric type can be used.
The sliding door 10 according to the present invention has a projecting component 10K for makeup projecting by a dimension δ with respect to a basic door surface 10S on a vertical side (in this example, the room side, hereinafter also referred to as the room side) which is planar. It is installed to do. Accordingly, the front end 34E of the upright 34 is retracted to a position having a gap Δ larger than the protruding dimension δ with respect to the basic door surface 10S of the sliding door so that the sliding door can be moved to the fully open state.

  The longitudinal airtight member 50C attached to the vertical frame 30, the leftward / rightward airtight member 50A attached to the upper frame 36, and the left / right airtight member 50B attached to the pallet 38 are the sliding doors in the fully closed state. It can be said that it is provided on one plane so as to abut on the vertical basic door surface except only a vertical airtight member 50D described later. Each of these airtight members is formed of a rubber material here, but may be, for example, a silicon material, and may be elastic so that it can be restored.

  The cross-sectional shape of the vertical 34 is formed by bending a metal plate into a rectangular shape, and a longitudinally extending groove 34 </ b> M is formed by using one end side of the metal plate taken out from the rectangular portion. In addition, a longitudinal airtight member 50D is disposed therein. Therefore, the position of the longitudinal airtight member 50D is somewhat different from the above-mentioned three airtight members on one plane, and somewhat from the plane to the vertical side (hereinafter also referred to as the room side). Separated. A portion protruding from the rectangular portion of the vertical (the lower side than the side 34B described later in FIG. 4) extends downward until reaching the low plane portion 38B described above. Accordingly, the longitudinal airtight member 50D is also disposed so as to reach the low flat surface portion.

  Accordingly, a portion (a portion protruding from the rectangular portion) extending from the door-side surface 34A that forms one side of the rectangular portion of the rectangular portion, which is a basic cross section of the vertical portion 34, is the vertical side of the hull 38. The end portion 38E and the vertical end portion of the upper frame 36 are in contact with each other, or are close enough to be separated from each other and face each other. The groove 34M is formed immediately next to the door end side surface 34A of the stand 34. That is, it is only separated from the door-end side surface 34A toward the door bottom side by twice the thickness of the metal plate forming the vertical. Accordingly, the vertical airtight member 50D disposed in the groove is disposed close to the vertical end 38E of the hull 38 and the vertical end of the upper frame 36, respectively. The groove 34M has a groove bottom adjacent to the other side 34B adjacent to one side 34A of the rectangle. As described above, the groove 34M is provided near the corner of the vertical 34. From the groove 34M at this position, the tip portion in the cross section of the vertical airtight member 50D protrudes toward the sliding door. In the case of this example, the above-described gap Δ is wider than the thickness of the human thumb, and is configured to prevent a hand from being accidentally pinched when the sliding door is opened and closed.

  Due to the existence of the gap dimension Δ, the sliding door 10 protrudes toward the room side with respect to the basic door surface 10S near the door bottom of the sliding door, extends in the vertical direction, and has a ridge portion 10T having a substantially rectangular cross section. Is provided. Accordingly, when the sliding door is fully closed, the longitudinal airtight member 50D comes into contact with the surface 10TA of the rectangular protrusion 10T facing the room (facing the longitudinal airtight member 50D). Thereby, it is possible to substantially prevent the collapse of the airtightness due to the fact that only the longitudinal airtight member 50D, which is one of the four airtight members surrounding the four sides of the sliding door 10 in the fully closed state, is shifted to the room side.

  However, in the vicinity of the upper and lower ends of the ridge portion 10T, generally, the surface 10TB facing the door end side of the ridge portion, the vertical side end surface of the upper frame 36, and the vertical side end surface 38E of the hull 38 There is a gap between the vertical end 50BE of the left-right airtight member 50B and the vertical end of the left-right airtight member 50A. However, if the shape and size of the protruding portion 10T are adjusted and designed so that the surface 10TB abuts against each of the vertical side end surfaces, there is no gap and airtightness can be maintained. The protrusion 10T in this case is made of a metal plate. However, when the sliding door 10 is fully closed, the protrusion 10T may be manufactured so that the surface 10TB is just in contact with each of the door bottom side end surfaces.

  However, a very slight gap may remain as a real problem. Therefore, a rubber body 52, which is an elastic member, is attached to the surface 10TB near the upper and lower ends of the ridge. The rubber body is attached to the metal plate-made protruding portion 10T by inserting and engaging the engaging protrusions protruding from the back surface of the rubber body into the holes 10TH provided in the plate portion having the surface 10TB. This rubber body can also be considered as a protrusion. On the other hand, a plate member 39 which is a separate part is integrated with the end surface 38E of the huller 38 by welding or the like. When the sliding door is fully closed, the surface 52S of the rubber member 52 of the protruding portion is the plate member. 39, thereby maintaining airtightness. The same applies to the upper frame 36.

  More precisely, the plate member 39 does not cover the outdoor O region (shaded portion) on the end surface 50BE of the left-right airtight member 50B (the same applies to the left-right airtight member 50A). If the length of the member itself up to the end corresponding to the hatched portion is appropriately set, the end surface of the hatched portion can directly contact the rubber body 52, and the airtightness is further improved. Further, even if the end surface position of the left-right airtight member is retracted from the outer surface (surface in the door butt direction) of the plate member by the thickness of the plate member 39, the rubber body 52 is laterally moved by its elasticity. You may have the softness | flexibility and thickness which can deform | transform so that it may contact | abut to the oblique line part of end surface 50BE of the airtight member 50B. The same applies to the left-right airtight member 50A.

  Further, as appears well in FIG. 4, the above-described groove 34 </ b> M is formed at one end of the metal plate member forming the rectangular main body 34 of the vertical 34, and the remaining end 34 </ b> C is extended in the left-right direction. . Further, the vertical end portion 10C of the edge member 10B made of a metal plate covering the door bottom end face of the sliding door 10 is bent so as to extend in the left-right direction, and the rectangular main body side that is more vertical than the end portion 34C. Is located. This is a so-called phase pile structure, and when a fire occurs, the metal plate end portions 34C and 10C are deformed so as to approach each other depending on the heating temperature. Air (oxygen) supply and flame propagation can be cut off.

  The above is an example in which the sliding door 10 is provided with the protruding protruding component 10K that protrudes in the vertical direction, but even if this component 10K is not provided, the existence of the above-described gap Δ between the sliding door and the vertical is as follows. it makes sense. That is, when opening and closing the sliding door in a state where the hand is placed against the basic door surface 10S on the door butt side, even if the hand is mistakenly positioned between the vertical and the sliding door, the gap Δ If the width is set wider than the thickness, an accident in which a finger is caught can be prevented and it is safe. Furthermore, it is possible to attach a decorative part that protrudes with respect to the basic door surface at the time of reform at a later date, which is convenient. The matters described in this paragraph are the same in the following examples.

  Next, another embodiment of the present invention will be described with reference to FIG. FIG. 7 can be compared with FIG. 4, and items not described here are the same as those in the previous embodiment. The major difference is that, in place of the vertical airtight member 50D provided on the vertical side of FIG. 4, in the door bottom side portion of the vertical side basic door surface of the sliding door 10, it protrudes to the vertical side and extends vertically. An elongated metal plate protrusion 10T ′ is provided, and a vertical airtight member 50D ′ is disposed in a vertical groove 34M ′ provided in the protrusion. When the sliding door is fully closed, the vertical airtight member 50D ′ is extended from the rectangular main body portion of the vertical 34 and left and right in the same manner as the end portion 34C forming one side of the above-described phase stack structure. It abuts on the end 34C ′ extending in the direction to ensure airtightness.

  Further, when fully closed, the rubber member 52 is brought into contact with the plate member 39 provided at the end 38E of the hull 38 instead of directly contacting the surface on the door end side of the protrusion 10T ′. The same applies to The same applies to the upper frame 36.

  As still another embodiment, the position of the groove 34M ′ provided in the protrusion 10T ′ of FIG. 7 is shifted by a predetermined amount toward the door end, and the longitudinal airtight member 50D ′ is In addition to being in contact with the above-described end portion 34C ′, the door member side portion is also in contact with the plate member 39. That is, the left side wall of the groove in FIG. 7 formed by the ridge portion 10T ′ and the portion to which the left rubber body 52 is attached are eliminated together with the rubber body, and the position of the groove 34M ′ is moved leftward. is there. The longitudinal airtight member is held by bonding or other means in the groove having the L-shaped cross section of the protrusion. This eliminates the need for a separate rubber body, simplifies the airtight structure of the sliding door, and reduces the cost.

The protrusions 10T and 10T ′ described above are mounted with parts made by bending a metal plate, but may be integrated with the sliding door 10.
As described above, the vertical end 38E of the huller 38 is separated from the vertical door basic door surface 10S of the sliding door by a gap dimension Δ, but in the conventional case, it is mounted on the huller 38. The left and right airtight members 50B that are being held are only separated by the width dimension of the portion that is not held by the hull and is exposed to the outside. In the invention of claim 2 of the present application, the portion of the high flat surface portion 38A corresponding to the difference in the separation dimension is lowered to the low flat surface portion 38B in a stepped shape, and the end portion of the region of the high flat surface portion lowered to the stepped shape, that is, The vertical end 38E of the huller is brought into contact with the sliding door-side protrusions 10T and 10T 'or the rubber body 52 attached to the protrusions to improve the airtightness.
The position of the end portion 38E is close to the edge member 10B on the end surface of the door butt when the sliding door 10 is fully closed, and the door side surfaces of the ridges 10T and 10T ′ provided adjacent to the edge member. Or the rubber body 52 provided on the side surface of the door. Generally speaking, it is a position near the door butt of the vertical basic door surface 10S.
Furthermore, in the positional relationship with the vertical 34, it is also the position of the door end side surface 34A forming one side of the vertical rectangular portion.

  The present invention can be used for sliding doors.
