Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an upper stopper structure for a guide rail for a folding door installed at the entrance of a bathroom or the like.

[Problems to be solved by conventional techniques and ideas] Generally, folding doors used in bathrooms, etc.
Opening options are often changed depending on the changing room or washing machine location. Therefore, a folding door (Japanese Utility Model Publication No. 57-20798) has been disclosed in which the right and left opening directions can be freely changed to accommodate such situations. This device is provided with upper and lower stoppers, and as shown in _FIG . Book)
Since it is installed in the upper frame 3, it is necessary to remove this screw b, move it to the door stile 1 on the opposite side, and tighten it again directly to the upper frame 3 with screw b, and the stopper S ₁
Although it was possible to remove it, it was necessary to work with the hand raised upwards, which was tiring. Moreover, since the upper frame 3 is equipped with screw threads, frequent changes in the opening direction have the disadvantage that the screws in the screw holes become crushed, making screwing impossible.

Therefore, as shown in Japanese Utility Model Application No. 58-67051,
The upper stopper consists of a lower stopper body, an upper stopper body, and a screw that tightens both.The guide rail is tightened by the stopper body and the stopper body, and is loosened by the screw. Attempts have been made to make the stopper fixed-mobile. By the way, in this case, the retaining body is rectangular in shape with short sides and long sides because it needs to be fitted loosely between the front and rear guide rails, rotated 90 degrees, and placed on the top of the guide rails. There is a need to
In this case, on the opposing edges of both guide rails, a drop-off preventer protrudes upward to prevent the guide roller from falling off, but the retaining side is
It has a substantially inverted shape so as to be latched to this drop-off prevention side. However, if you do this, it becomes necessary to turn the retaining side 90 degrees with the retaining side inserted deeply, which impairs workability, and the center part where the screw of the retaining side screws into is thin. Therefore, it is inevitably weak in strength, and when the screw is strongly tightened, there is a problem that the retaining side is greatly deformed toward the stopper body, and there is a risk of damage.

On the other hand, it has been proposed to make the retaining body have an inverted convex shape to strengthen the central part where the screw is screwed, but in this case, it is necessary to insert the retaining body upward from between the guide rails. Another problem arises in that the stopper cannot be stopped by the falling-off prevention side when it is turned, and if it continues as it is, the workability is poor and it cannot be adopted immediately.

[Means for Solving the Problem] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing an upper stopper structure for a guide rail for a folding door that can eliminate these drawbacks. Among the door frames to be erected, the bottom of the upper door frame that is long in the left and right direction is a bottom that opens in the shape of a long groove at approximately the center in the front and back direction and is divided into front and back parts, and the divided bottom is attached to the upper edge of the folding door. In addition to a pair of front and rear hanger rails on which a protruding hanger roller rolls, a falling-off prevention portion is formed on the opposing edges of both hanger rails to protrude upward to prevent the hanger roller from falling off. When attaching the upper stopper to the hanger rail, the upper stopper is integrally formed with a fitting part that fits into the opposing gap between both hanger rails to prevent rotation, and a pedestal part that comes into contact with the lower surface of the hanger rail. a stopper main body formed in the same shape as the stopper main body, and a stopper main body disposed on the upper side of the stopper main body, the length of the short side being set so as to fit between the opposing sides of both the hanger rails,
It consists of a rectangular retaining body with a screw hole in the center, and a screw that loosely penetrates a hole formed in the stopper body and screws into the screw hole. The hanger rail is configured so that both ends of the retaining body in the retaining position rotated 90 degrees from the passing position and the pedestal of the stopper body sandwich both hanger rails, and the retaining body is approximately The thick center convex part has an inverted convex shape and is configured to fit between the opposing guide rails in the above-mentioned retaining position so as to closely oppose the fitting part of the stopper body, and furthermore, the retainer body The length in the long side direction from the axis position of the screw hole in is set to the distance to the nearest side wall of the front and rear walls of the upper frame, and the length between the short side and long side of the retainer is set to A pair of diagonal corner portions among the four corner portions are formed into arc-shaped surfaces centered on the screw hole portion, and the rotation of the retaining body from the passing position to the retaining position is restricted. It is characterized by the following.

With this configuration, the present invention makes it possible to reliably restrict rotation beyond the retaining position even though the retaining body has an inverted convex shape.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawing, A is a folding door, and the folding door A is formed into a frame by frame materials such as vertical stile 1, upper and lower stile 1a, 1b, and middle stile 2, and the upper and lower doors provided on the frame side. It is installed in a door frame formed by the frames 3, 4 and the left and right door vertical frames 14, and one of the pair of left and right hanging rollers 5 provided at the upper end of the vertical stile 1 (for example, the right side ) is fixed so as not to move by an upper stopper _S1 fixed to the hanger rail 3a, as will be described later, and is opened and closed by the other (left) hanger roller 5 rolling on the hanger rail 3a. Everything is the same as before.

The upper door frame 3 is formed by extrusion molding, and its bottom side is opened in the shape of a long groove at approximately the center position in the front and rear direction, and is divided into front and rear parts.
A hanger rail on which the hanger roller 5 rolls is set on the bottom side 3a which is divided into the front and back. And this hanger rail 3a
A drop-off prevention part 3b for preventing the hanger roller 5 from falling off is formed on the opposing edge of the hanger rail 3a to protrude upward, and a gap A is provided between the opposing sides of the hanger rails 3a. ing. Furthermore, 3c
is the door frame side wall closer to gap A.

The upper stopper _S1 is composed of a retaining body 6 into which a seat nut 8 is integrally incorporated, a stopper body 7, and a screw 8, as described later, and the corresponding lower stopper _S2 is: 10 front pieces, 1 back piece
1, a seat nut 12, and a screw 13. These upper and lower stoppers S ₁ and S ₂ are screws 9,
13 and the seat nuts 8 and 12 are all made of synthetic resin or the like.

The retaining body 6 has a substantially rectangular shape consisting of a long side and a short side in a plan view, and has a substantially inverted concave shape in a side view, and has a concave surface 6b which is lowered further in the middle part of the upper surface 6a. This concave surface 6b is provided with a groove 6c so that the seat nut 8 constituting the screw hole of the present invention is inserted and locked only from the side, and a groove 6c is provided in the center of the concave surface 6b. A central hole 6d corresponding to the screw hole is drilled through the center hole 6d. Further, a protrusion 6e projecting downward is formed on the lower surface of the retaining body 6, so that the protrusion 6e is thick. Furthermore, the length A' of the short side of the retainer 6 is smaller than the opposing gap A of the guide rail 3a (A>A').
It is set to be. On the other hand, the retaining body 6
is the length of the center hole 6d in the long side direction from the axis,
The distance is set to be the distance to the side wall 3c on the near side of the upper door frame 3. In this way, the rectangular retaining body 6 whose lengths are set for the short and long sides has four corner parts depending on the long and short sides, and among these, a pair of corner parts 6f that are in a diagonal relationship
is formed in an arcuate surface 6f centered on the center hole 6d.

On the other hand, the stopper main body 7 has an elongated flat plate shape with the length of the short side set to be the same as the length A' of the short side of the retaining body. The portion 7b is attached to the pedestal 7a in the front-rear direction with both sides left open.
Further, the front and rear edges of the fitting portion 7b are bent upward to form vertical walls 7c, 7c having a substantially reverse concave shape.
In the concave groove 7d formed by this standing wall 7c,
The entire length of the retaining body 6 is set to fit inside. Furthermore, a lower recess 7e is provided in the center of the fitting portion 7b, and the projection 6e of the retainer 6 just engages with this recess 7e. Further, a center hole 7f corresponding to the center hole 6d is bored in the center of the recess 7c.

On the other hand, the front piece 10 of the lower stopper _S2 has a substantially angular shape, with a center hole 10b bored in the center of the upper surface 10a, and a back piece 1 in the middle of the hanging part 10c.
A cutout portion 10d is provided with a size that allows one to pass through. The back piece 11 is also formed in an angular shape with a bottom surface 11a and a standing wall 11b, and the height n of this standing wall 11b is set to be slightly smaller than the lower gap m of the protruding hanging side 4a of the lower frame 4. Further, a center hole 11c is bored in the center of the bottom surface 11a. Furthermore, a recess 11d is formed around the center hole 11c so that the seat nut 12 can be fitted therein.

In the embodiment of the invention constructed as described above, the upper stopper _S1 is attached to the guide rail 3a in the following manner. In other words, the tip of a screw 9 passing through center holes 7f and 6d formed in the stopper body 7 and the stopper body 6 is screwed into the seat nut 8, which has been assembled in advance into the stopper body 6, to temporarily assemble it. put. Then, the retaining body 6 is placed in a passing position in which it is fitted into the fitting portion 7b, and the retaining body 6 and the fitting portion 7 are
b between both guide rails 3a, and then
When the screw head of the screw 9 is pushed up and rotated 90 degrees, the retaining body 6 is lifted above the drop-off prevention part 3b and rotated 90 degrees. This 90 degree rotation is
This is ensured by the fact that the corners of the long and short sides form the arcuate surface 6f, but rotation beyond this point is ensured by the fact that the corner portions that do not form the arcuate surface 6f form the side wall 3.
c and is regulated, and the retaining body 6 is rotated 90 degrees from the passing position to a retaining position and is held in this position. Then, if the screw 9 is screwed in as it is, the retaining body 6 and the stopper body 7 will be tightly attached with the guide rail 3a being sandwiched between the upper and lower sides and the falling-off prevention part 3b being sandwiched between the upper and lower guide rails 3a of the upper stopper. The installation is completed. If it is desired to move the upper stopper, it is sufficient to loosen the screw 9 and move it along the guide rail 3a.

In this way, in this invention, the upper stopper is
The upper stopper 6 is composed of a retaining body 6 and a stopper main body 7, and the upper stopper 6 is formed in a substantially inverted concave shape, and has a thick protrusion 6e in the center in the gap between the guide rails 3a. Since the stopper body 7 is fitted into the stopper body 7, the rigidity of the retaining body itself is increased compared to the conventional one having an inverted concave shape.

Moreover, when tightening the retaining body 6 with screws, it is necessary to rotate it 90 degrees from the passing position to the retaining position, but this is because one corner part becomes an arc-shaped part 6f with the rotation center as the axis. However, rotation of more than 90 degrees is restricted because the other corner, which is not arcuate, is locked to the side wall 3c, and therefore the work of assembling the upper stopper is virtually impossible. In order to do this, it is sufficient to insert the retaining body 6 together with the fitting part 7b into the guide rail 3a, and then rotate the screw while pushing it up with a tool such as a screwdriver, which greatly improves work efficiency. Become.

By the way, the lower stopper S ₂ is installed using seat nut 12.
into the recess 11d carved in the bottom of the back piece 11. At this time, since the lower gap m of the protruding hanging side 4a is larger than the height n of the standing wall 11b of the back piece 11, this back piece 11 is inserted from below the protruding hanging side 4a and held. After that, insert the screws 13 into the table piece 10 from the top surface 10a to close the protruding hanging side 4a.
The lower stopper S 2 is fixed to the lower frame 4 by placing the lower stopper S ₂ on top of the lower frame 4 and tightening the screw 13 .

[Operation and Effect] In summary, the present invention is constructed as described above, and the upper stopper is composed of a retaining body and a stopper body, but the upper stopper is formed in a substantially inverted concave shape. The central part that fits between the front and rear guide rails is thicker, and the rigidity of the retaining body itself is significantly increased compared to the conventional one having an inverted concave shape.

Moreover, when tightening the retaining body with screws, it is necessary to rotate it 90 degrees from the passing position to the retaining position.
This is because one corner is an arc shaped part with the center of rotation as the axis, so it rotates without any problem, but if it rotates more than 90 degrees, the other corner part, which is not arc shaped, will turn around the upper door. The upper stopper is regulated to lock onto the side wall of the spring, and the work of assembling the upper stopper essentially involves inserting the retaining body into the guide rail together with the fitting part, and then tightening the screw with a tool such as a screwdriver. All you have to do is push it up and rotate it, which greatly improves work efficiency.
