Description

  The present invention relates to an improvement of a sliding door device called a barrier-free sash, in which a sliding door shoji is built in a window frame having a flat upper surface of a lower frame.

  In order to ensure the ease of movement of the elderly and the physically handicapped, the structure of a window frame that is called a barrier-free sash, with the upper surface of the lower frame flattened, is described in, for example, Patent Documents 1 to 4, etc. Various types have been conventionally known. In each of the structures described in these patent documents, the outer peripheral surface of the door wheel installed on the lower arm of the sliding door is a simple cylindrical surface, and the outer surface of the door wheel is in contact with the upper surface of the lower frame. It is a surface.

  In the case of such a conventional structure, since a special thing different from what was conventionally used as a doorwheel is used, unless it spreads widely in the future, there is a possibility that the cost will increase. In particular, at present, when repairing or replacing a broken trolley, the labor and cost required for obtaining the trolley may be higher than that of a general one where concave grooves are formed on the entire circumference. There is. Further, since the engaging portion between the door pulley and the lower frame cannot position the sliding door shoji in the indoor / outdoor direction, a structure for separately positioning the sliding door shoji in the indoor / outdoor direction is necessary.

  In consideration of such circumstances, a lower frame with a lower guide rail is used as the lower frame, and the upper edge of the lower guide rail is the part of the upper surface of the lower frame where people and objects move It is advantageous to adopt a structure that is positioned below the lower part. In this case, a recess is provided on the upper surface of the lower frame in the moving direction of the sliding door shoji, and the lower guide rail is provided so as to protrude upward from the bottom surface of the recess. Accordingly, there is an opening of the recess on the upper surface of the lower frame, and the upper edge of the lower guide rail is present at the center of the opening.

  The concave portion and the lower guide rail are provided over the entire length of the lower frame, whereas the length (width) of the sliding door shoji is shorter than the total length of the lower frame. For this reason, the opening part of the said recessed part and a part of length direction of the upper end edge of a lower guide rail are exposed without being covered with the said sliding door shoji. For this reason, not only the appearance of the said part worsens, but when a foreign material falls in the said recessed part, it becomes difficult to take out this foreign material. That is, since the upper end edge of the lower guide rail exists at an approximately middle portion of the opening of the recess, the opening is divided into two in the width direction and becomes narrow. As a result, when a foreign substance such as a pin falls into the recess, it is difficult to take out the foreign substance.

  In Patent Document 5, when a shutter panel is wound up by a part of a lift guide groove for guiding both side edges of a lift-type shutter, a portion exposed below the shutter panel is covered with a band-shaped sealing material. The structure is described. However, such a structure described in Patent Document 5 is intended only to cover the opening of the groove existing in the vertical direction, and covers the upper end opening of the groove existing on the upper surface of the lower frame of the sliding door device. It is not intended to be a thing. Moreover, it is difficult to apply to a sliding door apparatus having a complicated structure such as winding a strip-shaped sealing material by a winding mechanism and having a limited installation space.

  In consideration of the circumstances as described above, a lower frame having a lower guide rail on the upper surface is used, and the upper edge of the lower guide rail provided in the recess on the upper surface of the lower frame is used as the lower frame. It is conceivable to adopt a structure in which a portion of the upper surface is positioned below a portion where a person or an object moves, and the concave portion is closed with a cover band as the sliding door shoji moves. In this case, one end of the cover band is coupled to the lower end of the eaves constituting the vertical side of the sliding door shoji, and the intermediate or other end of the cover band is formed as an eave frame constituting the vertical side of the window frame. It can be considered to put in and out. However, when such a structure is adopted, due to the structure in which one end of the cover band is joined to the lower end of the bag, when the wind blows on the outdoor side surface of the sliding door shoji during rain, It has been found by the inventors' research that rainwater may blow out.

Japanese Utility Model Publication No.55-19814 JP 2000-96934 A Japanese Patent No. 3233920 Japanese Patent No. 3233921 JP-A-5-340173

  In view of the circumstances as described above, the present invention uses a lower frame having a lower guide rail on the upper surface, and the upper edge of the lower guide rail is placed on the upper surface of the lower frame. With the structure that is positioned below the moving part, the appearance of the upper surface of the lower frame is good, and on the premise of the structure that can prevent foreign matter from falling into the recess, it is possible to prevent the rainwater from blowing out indoors It was invented to realize the structure.

Of the draining device for sliding door shoji and the sliding door device of the present invention, the draining device for sliding door shoji described in claim 1 is a saddle that constitutes the vertical side of the sliding door shoji that is built horizontally on the lower frame. This is for discharging water that has entered the joint between the lower end and the end of the lower heel, which also constitutes the lower side, from the lower end opening of the heel.
In such a drainage apparatus according to claim 1, the ridge is an extruded mold member provided with first and second both plate portions that are provided in the vertical direction in a state of being separated in the moving direction of the sliding door shoji. It is made.
The lower rod is made of an extruded mold material and is fixedly coupled to the rod with one end face abutted against the inner surface of the lower end portion of the first plate portion.
Further, a door frame is fixed to a through hole portion formed in a horizontal plate portion constituting the lower collar. The door frame supports the door so that the door can rotate freely and the vertical position can be adjusted based on the rotation of the adjusting screw.
In addition, first and second through holes are formed in portions of both the first and second plate portions for insertion of tools for rotating the adjusting screw at positions aligned with the adjusting screw. ing.
Also, a bracket that closes the lower end opening of the rod is supported at the lower end of the rod, and a blocking wall is provided in the middle of the position where the first and second through holes are straightly connected on the upper surface of the bracket. And a third through hole is formed in a portion of the blocking wall that matches the first and second through holes.
Communication between the first and second through holes by the third through hole is blocked by a closing plate that is opened only when the tool is inserted. For this purpose, for example, a closing plate, which is a thin plate made of an elastomer such as rubber, provided with a slit in the diameter direction is provided in a portion adjacent to the third through hole, or the tool is provided in the third through hole portion. A reed valve-shaped closing plate is provided that is pushed open with the insertion.
Furthermore, a drainage channel is provided in the vertical direction of the bracket for discharging moisture that has flowed down to the upper surface of the bracket from the lower end opening of the basket.

According to the draining device for sliding door shoji of the present invention configured as described above, even when wind blows on the outdoor side surface of the sliding door shoji during rain, it is possible to prevent the rainwater from blowing out indoors.
In other words, when wind blows on the outdoor side surface of the sliding door shoji during rain, rainwater enters the upper side of the horizontal plate portion constituting the lower arm through the through hole provided with the door frame. Then, the rainwater enters the space between the first plate portion and the second plate portion through the first through hole formed in the first plate portion, and is formed on the second plate portion by riding on the wind. It tends to go to the second hole. However, since the third through hole existing between the second through hole and the first through hole is blocked by the closing plate, the rainwater flows downward after hitting the closing plate and the blocking wall. Then, it is discharged from the lower end opening of the culvert through the drainage channel. As a result, rainwater that has entered the space through the first through hole does not blow out indoors through the second through hole.

When implementing the draining device for sliding door shoji of the present invention, preferably, as described in claim 2, the bracket is a receiving bracket formed in a hollow box shape with the outer surface side of the bag open.
Also, one end of a belt-like flexible cover band that covers a portion of the upper end opening of the recess provided on the upper surface of the lower frame that is not covered by the sliding door shoji, And a locking side bracket having a locking portion.
And this latching side bracket is engaged with this receiving bracket in the state which entered the inside of the said receiving bracket, and the one end part of the said cover belt | band | zone is couple | bonded with the lower end part of the said collar.
With this configuration, it is possible to prevent water that has entered the upper part of the cover bracket from flowing into the upper surface of the cover band.
And it is the structure which couple | bonds the one end part of the said cover belt | band | zone with the lower end part of the said fence, and even if wind blows on the outdoor side surface of a sliding door shoji at the time of rain, it prevents that rainwater enters into an indoor side.

A sliding door device preferable for carrying out the sliding door shoji drainage device of the present invention, as described in claim 3, is capable of rotating a plurality of door wheels on the lower armor constituting the lower side, with the horizontal axis as the center. A lower frame formed on the upper surface of a lower guide rail for guiding the horizontal movement of the sliding door shoji by engaging the supported sliding door shoji and a recessed groove formed on the outer peripheral surface of each of these door wheels over the entire circumference. Including a window frame.
In particular, the lower guide rail is provided on the upper surface of the lower frame in a state of protruding upward from the bottom surface of the recess existing in the moving direction of the sliding door shoji, and the upper edge of the lower guide rail is the upper surface of the lower frame. Thus, it does not protrude above the portions present on both sides of the recess.
Further, by moving a cover band provided between the lower end portion of the ridge constituting the vertical side of the sliding door shoji and the end portion of the window frame, the upper end opening of the concave portion is moved along with the movement of the sliding door shoji. It covers so that the part which is not covered with the said sliding door shoji in a part may be covered.
The cover band is made of an elastic material that is flexible and rigid enough to be moved by pressing force.
Then, one end of the cover band is coupled to the lower end portion of the ridge by the locking bracket and the receiving bracket that constitute the sliding door shoji drainage device according to claim 2, and the middle of the cover band. The guide portion is guided to a guide passage provided in a guide member fixed to a continuous portion of the lower frame and the collar frame coupled at right angles to each other, and the moving direction is changed by 90 degrees from the horizontal direction to the vertical direction. . Then, a part of the cover band that moves in the vertical direction is present in the frame.

In the case of the sliding door device configured as described above, since a lower frame having a lower guide rail is used as a lower frame, as a door wheel provided on the lower arm of the sliding door shoji, a groove is formed on the outer peripheral surface over the entire circumference. The formed one can be used. For this reason, besides the cost of the door cart itself can be kept low, the sliding door shoji can be positioned in the indoor and outdoor directions at the engaging portion between the door wheel and the lower guide rail. Therefore, it is not necessary to provide a separate structure for positioning the sliding door screen in the indoor / outdoor direction, and the cost can be reduced from this aspect.
In addition, since the upper edge of the lower guide rail is positioned below the portion of the upper surface of the lower frame where people and objects move, the upper surface of the lower frame is made substantially flat so that the person And move objects easily.
In order to prevent the upper end edge of the lower guide rail from protruding upward, the upper end opening of the recess provided on the upper surface of the lower frame covers the portion not covered by the sliding door shoji with a cover band. The appearance of the upper surface of the lower frame can be improved, and foreign matter can be prevented from falling into the recesses.

It is made of an elastic material having such a rigidity that it can be moved by force. In the case of the present embodiment, as each of the cover bands 24a to 24d, the one having a circular sectional shape in a free state is used, and the thickness of each of the cover bands 24a to 24d is suppressed to be small. The rigidity is ensured. The bending directions of the cover bands 24a to 24d are directions in which the upper surfaces of the cover bands 24a to 24d are convex curved surfaces in a state where the upper end openings of the recesses 15a and 15b are covered. The reason for this is to ensure the height of each of the lower guide rails 14a and 14b while preventing interference between the cover bands 24a to 24d and the upper edge of each of the lower guide rails 14a and 14b.

  One end of each of the cover strips 24a to 24d is coupled to the lower end of the summing rods 8a and 8b or the butting rods 9a and 9b of the glass shojis 2a and 2b, respectively. As it moves, it is pushed and pulled. In the case of the present embodiment, one end of each of the cover bands 24a to 24d is coupled to the lower end of each of the flanges 8a, 8b, 9a and 9b by a structure as shown in FIGS. 7 to 8 show one end portion of the lower right cover band 24c in FIG. 2 and the lower end portion of the butting rod 9b at the same position with respect to the structure of the coupling portion. Even if the one end part of the upper left cover band 24a in FIG. 2 and the lower end part of the butting rod 9a at the same position are arranged in the connecting part, the structure can be made in the same manner except that the left and right sides are reversed. Further, the structure of the connecting portion between the one end portion of each of the remaining cover bands 24b and 24d and the lower end portion of each of the summoning rods 8a and 8b can be configured in substantially the same manner. However, with respect to the lower ends of the summoning bowls 8a and 8b, if necessary, a receiving bracket is fixed to the outer surface of the summing bowls 8a and 8b. One end of the cover strips 24b and 24d and the lower end of each of the summoning bowls 8a and 8b are joined.

In the case of the present embodiment, the base end portion of the locking side bracket 28 as shown in detail in FIGS. 9 to 11 is coupled and fixed to the upper surface of one end portion of the cover band 24c. This locking side bracket 28 is provided with a mounting base 29 in the lower half and a locking portion 30 in the upper half. Of these, the attachment base 29 is formed by providing legs 32 on the upper surface of the attachment plate 31. The locking portion 30 is formed in a state of being continuous from the upper end of the leg portion 32, and the width dimension can be elastically contracted. Such a locking part 30 is a locking notch 34 formed in a hollow box-shaped receiving bracket 33 as shown in FIGS. 7, 8 and 12-17, which is fitted and fixed to the lower end of the butting bar 9b. Based on the engagement, one end of the cover band 24c and the lower end of the butting bar 9b are coupled. Accordingly, the width W ₃₀ of the locking portion 30 in the free state is larger than the width W ₃₄ of the locking notch portion 34 (W ₃₀ > W ₃₄ ). In addition, in order to be able to insert the said locking part 30 in the said locking notch part 34, this locking notch part 34b in the part which aligns with this locking notch part 34 in the lower end outer wall of the said butting rod 9b. A notch having a size larger than the notch 34 is formed.

  The locking side bracket 28 is integrally formed by injection molding an elastic material such as a synthetic resin such as polyamide, and the planar shape of the locking portion 30 is connected to the locking notch portion 34. The front side in the insertion direction (the left side in FIGS. 7 to 10) has a substantially V-shape with a narrower width. Therefore, when the locking side bracket 28 is pushed into the receiving bracket 33 from the outer surface side of the butting rod 9b (the surface side facing the flange frame 5b), the locking portion 30 is not locked. A force in the direction of elastically reducing the width dimension acts by engagement with both side edges of the notch 34 in the width direction. On the other hand, in a state in which the locking portion 30 is inserted into the receiving bracket 33, even if a force in a direction in which the locking portion 30 is pulled out from the inside of the receiving bracket 33 acts, the locking portion The force in the direction of reducing the width dimension of 30 does not act.

Further, both end portions of the locking portion 30 are bent collar portions 35, 35 that are bent substantially inwardly in the radial direction. In the case of the present embodiment, the knobs 36 and 36 are extended from the inner diameter side end portions of the two bent hook portions 35 and 35 in a direction away from the semicircular arc of the locking portion 30. The width dimension of the locking part 30 can be reduced to a width dimension W ₃₄ or less of the locking notch part 34 by reducing the distance between the knobs 36 and 36.

  As shown in FIG. 18, the above-described locking side bracket 28 is coupled and fixed to the upper surface of one end of the cover band 24 c via a coupling bracket 37. Prior to the locking-side bracket 28, the coupling bracket 37 is coupled and fixed to the upper surface of one end of the cover band 24c by a rivet. In this state, as shown in FIG. 19, the distance between the pair of holding portions 38, 38 provided at both ends of the coupling fitting 37 is still open. When the locking bracket 28 is coupled and fixed to the upper surface of one end portion of the cover band 24 c, a pair of positioning projections formed on the lower surface of the mounting plate portion 31 are disposed on both ends of the coupling bracket 37. In a state of being engaged with the formed circular hole, both the restraining portions 38, 38 are bent in a direction approaching each other from the state shown in FIG. 19 to the state shown in FIG. 38, the upper surface of the mounting plate portion 31 is held down. As a result of this operation, as shown in FIG. 18, the locking bracket 28 is fixedly coupled to the upper surface of one end of the cover band 24c.

  As described above, the receiving bracket 33, which is fitted and fixed to the lower end of the butting bar 9b in order to connect the one end of the cover band 24c, to which the locking bracket 28 is connected and fixed to the upper surface, The locking notch 34 is formed in an open box shape and on the outer surface side of the butting bar 9b.

In this state, the horizontal portion side opening ends of the guide passages of the respective guide brackets 65a and 65b are arranged at the horizontal end upper ends of the respective concave portions 15a and 15b. Each of the storage portions 66a to 66d provided in 5b is aligned with the lower end opening.

  In the illustrated example, of the guide brackets 65a and 65b, the guide bracket 65a that faces the summing collars 8a and 8b prevents the summing collars 8a and 8b from colliding with the collar frames 5a and 5b. In order to provide a function as a stopper, the length of the lower frame 4 is ensured. On the other hand, the guide bracket 65b facing the butting rods 9a and 9b is arranged in the length direction of the lower frame 4 so that the butting rods 9a and 9b can be sufficiently close to the rib frames 5a and 5b. The dimensions are reduced. There is no fundamental difference between the guide brackets 65a and 65b as to the shape of the guide passage provided inside.

  In addition, in order to provide the storage portions 66a to 66d, as shown in FIGS. 2 to 4, the flange frames 5a and 5b are respectively provided with inner brackets 68a and 68b on the inner side surfaces of the flange frame bodies 67a and 67b. Consists of butt joints. And a part of clearance gap between the inner surface of each of these collar frame main bodies 67a and 67b and the outer surface of each of these inner side brackets 68a and 68b is made into said each accommodating part 66a-66d. The inner brackets 68a and 68b are not provided at the lower end portions of the flange frame bodies 67a and 67b, and a part of the guide brackets 65a and 65b are abutted against the lower end portions.

And the guide grooves 25a and 25b and the guide passage are made continuous. With this configuration, the cover bands 24a to 24d can be transferred between the guide grooves 25a and 25b and the guide passage.

  In the case of the present embodiment configured as described above, if each of the glass shojis 2a and 2b is moved, the summing rods 8a and 8b and the butting rods 9a and 9b of the glass shojis 2a and 2b and the respective rod frames 5a. The cover bands 24a to 24d are transferred to and from 5b. The portions of the recesses 15a and 15b that are not covered with the lower collars 7a and 7b of the glass shojis 2a and 2b are covered with the cover bands 24a to 24d. That is, when each of the scissors 8a, 8b, 9a, 9b moves away from the opposing scissors frames 5a, 5b as the glass shojis 2a, 2b move, the lower ends of the scissors 8a, 8b, 9a, 9b The cover strips 24a to 24d coupled to the guide portions are pulled out from the storage portions 66a to 66d of the collar frames 5a and 5b while the direction is changed by 90 degrees in the guide passage portions provided in the guide brackets 65a and 65b. It is. The cover bands 24a to 24d are bridged between the lower ends of the flanges 8a, 8b, 9a and 9b and the lower ends of the flange frames 5a and 5b. The upper end openings of 15a and 15b cover the exposed portions between the lower ends of the flanges 8a, 8b, 9a and 9b and the lower ends of the flange frames 5a and 5b. In this state, in the upper surface of the lower frame 4, the appearance between the lower end of each of the flanges 8a, 8b, 9a, 9b and the lower end of each of the flange frames 5a, 5b is improved, and It is possible to prevent foreign matter from falling into the recesses 15a and 15b at the portion between them.

  In the case of the present embodiment, both side edges of the cover bands 24a to 24d, which are pulled out from the storage portions 66a to 66d and cover a part of the recesses 15a and 15b, are connected to the guides. It will be in the state latched by groove 25a, 25b. For this reason, it can prevent reliably that the both-ends edge of each of these cover strips 24a-24d floats from the opening edge part of said each recessed part 15a, 15b. As a result, it is possible to effectively prevent fine foreign matter from getting into the recesses 15a and 15b and catching something on the cover bands 24a to 24d.

  On the other hand, when each of the scissors 8a, 8b, 9a, 9b approaches the facing scissors frames 5a, 5b as the glass shojis 2a, 2b move, the lower ends of the scissors 8a, 8b, 9a, 9b The cover strips 24a to 24d coupled to the guide frames 5a and 5b are pushed into the storage portions 66a to 66d of the flange frames 5a and 5b while the direction of the guide path portions provided in the guide brackets 65a and 65b is changed by 90 degrees. It is. Each of the cover strips 24a to 24d has a property such as a metal tape measure and has a certain degree of rigidity in the pressing direction. Therefore, as the glass shojis 2a and 2b move, the storage portions 66a to 66d. It is securely pushed into 66d.

  Further, in the case of this embodiment, even when wind blows on the outdoor side surface of the glass shoji 2b (same as in 2a) at the time of rain, it is possible to prevent the rainwater from blowing out indoors. That is, when wind blows on the outdoor side surface of the glass shoji 2b during rain, rainwater enters the upper side of the horizontal plate 46 constituting the lower rod 7b through the through hole 47 provided with the door frame 48. . The rainwater enters the space 70 between the first plate portion 42 and the second plate portion 43 through the first through hole 52 formed in the first plate portion 42 of the butting rod 9b. . If no countermeasures are taken, the rainwater that has entered the space 70 in this way enters the space 70 from other parts such as a gap at the joint between the upper heel 6b and the butting butt 9b. Along with rainwater, it rides on the wind toward the second through-hole 53 formed in the second plate portion 43, and blows out of the butting rod 9b from the second through-hole 53. As is clear from FIG. 21, the rainwater blown out of the butting rod 9b from the second through hole 53 reaches the indoor side without being blocked by the sealing material or the like, and wets the curtain or the floor surface.

On the other hand, in the case of the present embodiment, the third through hole 57 existing between the first through hole 52 and the second through hole 53 is blocked by the thin plates 59, 59. Rainwater that has entered the space 70 from the first through hole 52 hits both the thin plates 59 and 59 (actually, the upstream thin plate 59 and the downstream thin plate 59 serve as auxiliary roles) and the blocking wall portion 56. It flows downward and is discharged from the lower end opening of the butting rod 9b through the drainage channel 61. As a result, rainwater that has entered the space 70 through the first through hole 52 is not blown out indoors through the second through hole 53. Also, rainwater that has entered the space 70 from the other part is guided by the inclined surface 62 to reach the drainage channel 61 and is discharged from the lower end opening.
In this way, even when rainwater entering from the through hole 47 is prevented from blowing out indoors, the height position of the door wheel 16b by the driver 54 is adjusted by the slits 60 of the two thin plates 59, 59. This can be done easily by inserting the driver 54 while pushing it open.

  The illustrated embodiment has been described when the present invention is applied to a sliding door. On the other hand, the present invention is not limited to the sliding door as shown in the figure, and can be implemented as long as it is a sliding door device that moves the shoji in the horizontal direction to open and close the opening. For example, the present invention can be implemented even with a sliding door provided with only one sliding door shoji.
