Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door provided in a shed, a small warehouse, or other sheds.

[0002]

2. Description of the Related Art Two sliding front and rear doors can be opened and closed laterally along two front and rear grooves (rails), and when both doors are closed, the vertical frame portions are overlapped with each other. But,
A gap is created between the overlapping surfaces of the vertical frame parts, and insects, dust, wind, and rain easily enter. Therefore, there is one in which a packing is provided between the overlapping surfaces of the vertical frame portions so as to close the gap between the overlapping surfaces (for example, Design Registration No. 703352).

[0003]

The packing has one elastically deformable fin-shaped piece, and is fixed to one of the overlapping vertical frame parts of the front and rear doors and the fin-shaped part is provided on the other vertical frame part. The tips of the pieces come into contact with each other. However, if such a packing is set to a length such that the tip of the fin-shaped piece lightly abuts on the other vertical frame, it may cause a typhoon due to the gap between the door and the groove or variations in the door dimensions. The door tends to rattle back and forth due to wind load, which causes a gap between the overlapping surfaces of the vertical frames of the front and rear doors, reducing the original function of preventing insects, wind and rain from entering. To do. That said, if the fin-like piece is made thick and closed to increase the airtightness in the gap between the overlapping surfaces of the vertical frame, the packing will have a sliding contact resistance with the vertical frame when opening and closing the door. Is large, opening and closing operations are heavy, and it is easy to wear early.
The present invention has been made in order to solve such a problem, the door can be opened and closed easily, the wear of the packing can be reduced, and even if the door rattles, insects and wind and rain can be prevented from entering. The purpose is to provide a sliding door.

[0004]

SUMMARY OF THE INVENTION The present invention is a sliding door in which a vertical frame portion of a front door and a vertical frame portion of a rear door overlap each other when a front door and a rear door which can be opened and closed in the left-right direction are closed. In the above, the vertical frame part of the front door is provided so as to project rearward, and packing is attached to the front side of the vertical frame part of the rear door, and the packing is vertically mounted on the front surface of the vertical frame part of the rear door. A substrate portion that is superposed and fixed in a direction, an elastically deformable short fin-shaped piece that protrudes forward from one end of the substrate portion in the left-right direction and that abuts on the rear surface of the vertical frame portion of the front door in the closed state, Cross-sectional groove shape having a long fin-like piece having a length that projects forward from the other end in the left-right direction of the base plate portion, and is close to or in contact with the closing direction side surface of the vertical frame part of the closed front door. It is characterized in that it is formed in. The board portion of the packing is joined with a double-sided adhesive tape on the front surface of the vertical frame portion of the rear door,
It is fixed with a stopper.

[0005]

[Operation] In a normal state without a typhoon, even if the short fin-shaped pieces are set to lightly contact the vertical frame of the front door, the short fin-shaped pieces cause the gap between the overlapping surfaces of the vertical frame of the front and rear doors. Since the closed state is maintained, the door can be opened and closed easily, and the wear of the packing can be reduced. When the front and rear doors rattle back and forth due to wind load during a typhoon, a gap is created between the short fin-shaped piece and the vertical frame of the front door. It is possible to prevent further invasion by being blocked by the piece. By using the double-sided adhesive tape and the fastener together, the packing can be mounted vertically and straightly on the front surface of the vertical frame portion of the rear door.

Forward facing wall 18 bent at a right angle to the front
It is composed of

As shown in FIG. 3, on the front side of the vertical frame portion 10 of the rear door 7, a concave groove 19 for mounting the packing 20 is provided in the vertical direction, and a rectangular mounting hole 19a is vertically formed in the concave groove 19. It is provided with a predetermined pitch in the direction. The packing 20 is a plastic molded product molded in a groove shape in cross section, and includes a belt-shaped substrate portion 21 made of a hard synthetic resin, and left and right elastically deformable short fin-shaped pieces 22 and long fin-shaped pieces made of a soft synthetic resin. 23 and 23 are integrally extruded. In FIG. 1, the short fin-shaped piece 22 is provided so as to project forward from the left end of the base plate portion 21 and has a cross-sectional arc shape whose front end bends in the opening direction of the rear door 7 and a vertical frame when the front door 6 is closed. It is formed to have a length that elastically contacts the rear surface of the rear wall 13 of the vertical frame portion 9 so as to close the gap g between the portions 9 and 10. On the other hand, the long fin-shaped piece 23 is provided so as to project straight from the right end of the base plate portion 21 to the front side, and when the front door 6 is closed, has a slight distance w from the closing side surface 14a of the front wall 14 of the vertical frame portion 9. It is formed to have a length which is placed close to and opposed to each other. The length of the long fin-shaped piece 23 is set to a length equal to or larger than the gap g, and the wrap amount d with the side surface 14a in the closing direction is slightly lapped even when the front and rear doors 6 and 7 rattle to the maximum. But it is set to remain. Further, the interval w is set to a dimension in which the long fin-shaped piece 23 comes into contact with the side surface 14a in the closing direction only when the front and rear doors 6 and 7 rattle to the maximum. You may make it contact | abut to the closing direction side surface 14a.

After the packing 20 is molded, a double-sided adhesive tape 24 is attached to the back surface of the base plate portion 21, and then a mounting hole 26 through which a rivet 25 is passed through the base plate portion 21 and the double-sided adhesive tape 24 in a vertical direction. It can be pressed with a predetermined pitch. The rivet 25 is a plastic molded product such as polyacetal. A rivet 25 is provided with a head portion 28 at one end of a square tubular leg portion 27, and a pair of left and right elastically non-return pawls 29 are provided in the middle portion of the leg portion 27. There is.

Next, an example of the order of attaching the packing 20 will be described. The rivet 25 is attached in advance from the front side between the left and right long and short fin-shaped pieces 23, 22 to the mounting hole 26 of the board portion 21.
First, the check claw 29 is passed to a depth at which the check claw 29 projects rearward from the double-sided adhesive tape 24 on the back surface side of the substrate portion 21. Next, while the protective paper (not shown) that is removably attached to the double-sided adhesive tape 24 is peeled off, the substrate 21 is attached to the rear door 7
At the same time as it is attached to the groove 19 of the rivet 25 via the double-sided adhesive tape 24, the tip of the leg portion 27 of each rivet 25 is inserted into the groove 1.
9 is pushed into the mounting hole 19a through the elastic deformation of the check claw 29, and when the check claw 29 projects to the back side of the concave groove 19, the check hole 29a engages with the mounting hole 19a in a retaining state, and the head 2 of the rivet 25
8 and the inner surface of the concave groove 19 between the substrate portion 21 of the packing 20.
Are fixed in a sandwiched state.

At this time, the mounting pitch of the rivet 25 is made relatively short and the rivet 25 is sequentially fixed to the rivet 25 so that the attachment position of the packing 20 can be easily determined and the packing 20 can be easily straightened along the concave groove 19. Can be attached to. In addition, since the packing 20 is bonded with the double-sided adhesive tape 24 and further fixed with the rivet 25, the mounting strength can be increased. Even if the double-sided adhesive tape 24 deteriorates with time, the packing 20 will not come off due to the fixing force of the rivets 25. Only the uppermost or the lowermost (lowermost in the illustrated example) mounting hole 19a of the group of mounting holes 19a vertically arranged in the recessed groove 19 of the rear door 7 with a predetermined pitch is attached to the leg portion 27 of the rivet 25. The rivet 25 and the mounting hole 19a, which are mounted on the packing 20 in advance, are formed by forming the other mounting holes 19a so as to have a shape that exactly matches the cross-sectional shape, and forming the other mounting holes 19a longer than the longitudinal length of the cross section of the leg portion 27. Even when the and are displaced, the positional displacement can be absorbed by the margin length of the mounting hole 19a, and the rivets 25 can be sequentially and reliably stopped in a reliable manner.

The packing 20 attached in this way
When the front and rear doors 6 and 7 are closed, the short fin-shaped piece 22 comes into elastic contact with the rear surface of the rear surface wall 13 of the vertical frame portion 9 of the front door 6, and the long fin-shaped piece 23 of the vertical frame portion 9 extends. Of the front facing wall 14 abuts on the side surface 14a in the closing direction or faces the side wall 14a at a slight interval. Therefore, in the normal state, the gap g between the overlapping surfaces of the vertical frame portions 9 and 10 of the front and rear doors 6 and 7 is closed by the short fin-shaped piece 22 to prevent insects, dust, rain, etc. from entering through the gap. it can. Further, the short fin-shaped piece 22 is lightly brought into contact with the rear wall 13 of the vertical frame portion 9, so that the front and rear doors 6 and 7 can be opened / closed easily, and the wear damage of the short fin-shaped piece 22 can be reduced. When the front and rear doors 6, 7 rattle back and forth due to wind load such as during a typhoon, a gap is created between the short fin-shaped piece 22 and the vertical frame portion 9 of the front door 6, and insects, dust, wind, rain, etc. are generated from this gap. Even if it enters, it is blocked by the long fin-shaped piece 23 and falls downward along the groove between the short fin-shaped piece 22 and the long fin-shaped piece 23, so that it can be prevented from further entering the inside. Since the long fin-shaped piece 23 is in contact with or close to the side surface 14a of the vertical frame portion 9 in the closing direction, it is in sliding contact with the vertical frame portion 9 of the front door 6 as the front and rear doors 6 and 7 are opened and closed. There is no such thing,
Therefore, it is not subject to wear damage.

The rivet 25 may be detachably fixed so that the packing 20 can be replaced. Instead of the rivet 25, other fasteners such as screws may be used.

[0013]

According to the present invention, in a normal state, even if the short fin-shaped piece is set to slightly contact the vertical frame of the front door, the short fin-shaped piece overlaps the vertical frame of the front and rear doors. Since the state in which the gap between the surfaces is closed is maintained, the opening / closing operation of the door can be performed lightly, and the wear of the packing can be reduced. In the event of a typhoon, the front and rear doors rattle, and a gap is created between the short fin-shaped piece and the vertical frame of the front door. Can be prevented from entering. By using the double-sided adhesive tape and the stopper together, the packing can be easily and firmly attached vertically straight on the front of the vertical frame of the rear door, and even if the double-sided adhesive tape deteriorates with time, it is fixed by the stopper. It does not come off and has excellent durability.
