Description

Description: TECHNICAL FIELD The present invention relates to a door travel guide device applied to a foldable door partition panel, and is particularly characterized by means for preventing a lower runner from coming off from a lower guide rail. Have.

[Conventional technology]

In folding doors and the like, the weight of the door is generally supported by the upper runner with respect to the upper guide rail, and in order to prevent the door from wobbling at the time of opening and closing, a lower runner is provided to guide traveling along the lower guide rail. As a conventional lower runner,
For example, as shown in Japanese Utility Model Publication No. 63-46572 and Japanese Utility Model Publication No. 60-3910, there is a roller or pin structure that rotates around a vertical axis. In addition, there is a slide block as shown in Japanese Utility Model Publication No. 62-10384.

[Problems to be Solved by the Invention]

The lower runner with a roller structure or pin structure has a drawback that it easily comes off from the guide rail when the door swings in the longitudinal direction of the rail centering on the upper runner, and especially when the door is operated suddenly. It is easy to occur.

In this respect, since the slide block structure is engaged and guided with respect to the guide rail so as not to come off, the lower runner does not come off from the guide rail even if a sudden operation is performed. However, compared with the lower runner of the roller structure, the frictional resistance during opening and closing movement is large, and the lightness during operation is inferior. Further, prior to the assembling of the door, it is necessary to assemble the lower runner into the guide rail in advance, which is troublesome to assemble. It is possible to provide a notch in a part of the guide rail and to assemble the lower runner from this notch later, or the appearance is bad and it is easy to get caught at the notch.

The present invention solves the drawbacks of the conventional lower runner, and an object thereof is to obtain a travel guide device for a door provided with a lower runner that does not fall off from the lower guide rail and that can be opened and closed easily. It is in.

Another object of the present invention is to assemble the lower runner to the guide rail as easily as that of the conventional roller structure,
It is to improve the workability on site.

Another object of the invention is to obtain a lower runner which is particularly suitable for external folding doors.

[Means for Solving the Problems]

The lower runner 6 of the present invention has a mounting means as shown in FIG.
The runner body 31 is attached to the door 3 via the runner body 31. The runner body 31 rotatably supports a roller 32 rolling on the outer surface of the lower guide rail 8 about a horizontal shaft 33. It is a requirement that the lower end of the main body 31 is provided with an engaging body 41 that is engaged with the inside of the guide groove 28 and wraps around below the wall member 29 on the guide groove 28 side.

Further, the runner body 31 is supported so as to be vertically movable with respect to the mounting means 34, and the runner body 31 is provided between the runner body 31 and the mounting means 34.

[Action]

The lower runner 6 rolls the outer surface of the lower guide rail 8 in the longitudinal direction of the lower guide rail 8 via a roller 32 that is rotatable around a horizontal shaft 33.

Since the runner main body 31 is vertically movable with respect to the mounting means 34 and is urged down by the spring 39, the roller 32 is always supported on the receiving surface 30 of the lower guide rail 8 even when the door 3 or the like moves vertically. It rolls in a state of elastic contact and helps prevent the roller 32 from falling off.

In addition, when the roller 32 tries to float further from the lower guide rail 8, the engagement body 41 abuts against the wall member 29 on the guide groove 28 side to prevent the roller 32 from falling off.

The engagement body 41 projects from the lower end portion of the runner body 31 so as to go under the wall member 29 on the guide groove 28 side.

The hanging height of the door 3 can be adjusted with.

In FIG. 1, the lower guide rail 8 is formed in a C-shaped cross section having a guide groove 28 that opens upward. The upper surface opening width of the guide groove 28 is defined by the front and rear wall members 29 that project inward, and a horizontal receiving surface 30 that guides the roller 32 of the lower runner 6 to run is formed on the outer side of the upper and lower ends of the opening. It is formed in a supplementary shape.

In FIGS. 1 and 4, the lower runner 6 includes a runner body 31 which is a plastic molded product, a pair of rollers 32 arranged before and after the runner body 31, a horizontal shaft 32 which rotatably supports the rollers 32, and a runner. Mounting plate for attaching the main body 31 to the door 3
It consists of 34 and hinge 35. The mounting plate 34 is an example of the mounting means referred to in the present invention.

The runner body 31 is formed in a thin rectangular box shape in the front-rear thickness, and has a groove 36 that opens toward the upper surface inside. This groove
The mounting plate 34 is inserted into the mounting plate 36, and the horizontal shaft 33 is passed through the vertically extending long hole 37 provided in the plate surface, so that the runner main body 31 can be moved up and down with respect to the mounting plate 34. Connect to prevent coming off. As shown in FIG. 2, a groove 36 sandwiching the horizontal axis 33 therebetween.
Spring grooves 38 are formed at two places on the right and left sides of the runner main body 31 by the compression coil type springs 39 mounted on the spring grooves 38.
Is pushed down toward the lower guide rail 8 and urged.

The roller 32 has a flange 40 at its inner end, and the flange 40 is supported by the receiving surface 30 so as to be restricted by the inner surface of the receiving surface 30 and travels on the lower guide rail 8.

The roller 32 runs while rolling on the receiving surface 30.
When an upward force is applied to 32, the wheel is easily derailed from the receiving surface 30. In order to prevent this, the runner body 31 is pressed downward by the spring 39 and then the engagement body 41 is provided at the lower end of the runner body 31.

1 and 4, the engaging body 41 is formed so as to project rearward at the lower edge rear edge of the runner body 31, and is engaged with the lower end portion of the runner body 31 in the guide groove 28 of the lower guide rail 8. The united body 41 wraps around the lower side of the wall member 29 in a non-contact manner, and when the roller 32 tries to float up from the receiving surface 30, the engagement body 41 makes abutting engagement with the wall member 29, The runner body 31 is restricted from coming out of the guide groove 28.

Corresponding to the engaging body 41, a recess 42 is formed in a notch on the lower edge front edge side of the runner body 31. The recessed amount of the recessed portion 42 substantially corresponds to the rearward protruding amount of the engagement body 41. That is, as shown in FIG. 4, the engagement body 41 is provided in a state having a notch in the middle across the left and right of the runner body 31, and the recess 42 is formed.
Are formed over the entire left and right width of the runner body 31.

In FIG. 7, when the opening width B of the guide groove 28 is used as a reference, the front-rear width b of the runner body 31 is set smaller than the opening width B. Further, the front-rear distance C between the protruding end of the engagement body 41 and the recess 42 is set to be slightly smaller than the opening width B of the guide groove 28. By setting the dimensions in this way, the lower end of the runner body 31 can be inserted while the entire lower runner 6 is being tilted while the lower end of the runner body 31 is inserted into the guide groove 28. After this, the runner body 31 is returned to the normal standing posture, and the roller 32 is placed on the receiving surface 30.
Can be easily assembled to the lower guide rail 8. At this time, the recess 42 acts so that the engaging member 41 goes around the wall member 29 without coming into contact with and interfering with the wall member 29. That is, the lower runner 6 can be easily post-assembled with the lower guide rail 8 installed.

When the lower runner 6 is attached to the door 3, the lower runner 6
Since it does not tilt, as described above, the runner body
The 31 and the engaging body 41 do not slip out of the guide groove 28.

In FIG. 4, the hinge 35 for the lower runner 6 has substantially the same specifications as the hinge 11 for the upper runner 5, and the upper end 34a of the mounting plate 34 is caulked and fixed to one hinge plate 17. , The other hinge plate 16 is fixed to the door with screws. At this time, the central axis of the hinge shaft 18 is also aligned with the upper and lower hinges 11.35.

According to the lower runner 6 configured as described above, when the one door 3 is pushed and pulled to open and close the folding door 2 as shown in FIG. 6, the roller 32 rolls on the lower guide rail 8. Since the door 3 is moved to move, the opening / closing operation can be performed easily. The roller 40 has its flange 40, which is regulated to move in the front-rear direction by the receiving surface 30 on the rail, and the front-rear surface 31a of the runner body 31.
-Since 31b is close to the wall members 29, 29, the door 3 does not sway back and forth when traveling.

For example, when the lower end side of the door 3 is suddenly pushed and pulled, the door 3 receives a swinging moment along the longitudinal direction of the lower guide rail 8 about the roller 15 of the upper runner 5,
At the same time, the roller 32 of the lower runner 6 tends to float away from the receiving surface 30. However, at the same time when the runner body 31 tilts, the engaging body 41 is supported by the wall member 29 so as not to float, and further tilting is prevented, so that the lower runner 6 does not fall off the lower guide rail 8 and the door 3 can immediately return to the normal suspension posture.

In particular, as shown in FIG. 6, when the folding door 2 is folded outward (forward), the lower ends of the doors 3 tend to tilt obliquely rearward, but the engagement body 41 projects to the rear edge of the lower end of the runner body 31. Since it is formed, engagement with the wall member 29 satisfactorily abuts and regulates the removal of the lower runner 6 from the lower guide rail 8.

When the lower runner 6 is assembled to the lower guide rail 8, if the horizontal shaft 33 is positioned above the upper half of the long hole 37, the runner main body 31 can move in accordance with the floating operation of the roller 32.
Since the roller 32 is pushed out by the spring 39, the roller 32 can be prevented from separating from the receiving surface 30, and the lower runner 6 can be more reliably prevented from coming off in combination with the tilting prevention operation by the engaging body 41 described above.

Second Embodiment FIG. 8 shows a second embodiment in which the present invention is applied to the lower runner of the partition panel 3a. In this case, the mounting means 34 for the partition panel 3a of the runner body 31 is different from that of the first embodiment.

That is, the attachment means 34 is fixed to the runner main body 31 and is erected, a support shaft 44, a case 45 that is embedded in the lower end of the panel 3a and supports the support shaft 44 in a vertically slidable manner, and is mounted inside the case 45. The runner body 31 is pressed against the lower guide rail 8 via a support shaft 44, and a spring 39 is provided. The partition panel 3a is
Since it swings in the front-rear direction about the support shaft 44 when opening and closing, the front-rear width of the runner body 31 is made smaller than the inner surface width of the cover 46 fixed to the lower end of the panel 3a. Reference numeral 47 is a retaining pin for the support shaft 44.

[Third Embodiment] FIG. 9 shows a third embodiment of the present invention in which the form of the hinge 35 is changed. In this case, the plan view shapes of the pair of hinge plates 16 and 17 are transformed into crank shapes that can be overlapped with each other, and one hinge plate 16 is embedded and fixed in the meat wall of the door 3. In this way, the crank-shaped hinge plate 16
-When the lower runner 6 and the door 3 are connected at 17, the hinge shaft 18 can be positioned outside the lower runner 6 and the side edge of the opening frame 1a can be completely covered by the door 3, especially when an externally mounted folding device is used. It is advantageous for improving the appearance of the door when it is fully closed.

[Fourth Embodiment] FIG. 10 shows a fourth embodiment of the present invention. In this case, receiving surfaces 30 are provided on the front and rear sides of the lower guide rail 8, and standing walls 48 are provided at the inner ends of the receiving surfaces 30. And, the roller 32 does not have the flange 40, but its inner side surface 32a abuts against the standing wall 48,
Movement in the front-back direction is restricted.

[Fifth Embodiment] FIG. 11 shows a fifth embodiment of the present invention. In this case, the lower runner 6 supports the roller 32 rotatably by the inclined horizontal shaft 33 in each embodiment. Different from Thus, the horizontal axis
33 may be an inclined axis, and may be arranged in a zigzag pattern along the longitudinal direction of the lower guide rail 8.

[Another embodiment example]

In addition to the above, only one roller 32 may support the runner main body 31 for traveling, and the outer shape thereof may be formed into a spherical shape or an aspherical ball shape.

As can be understood from the above-described embodiments, the mounting means represented by the mounting plate 34 can be freely changed according to the mounting target of the lower runner 6, the structure of the door 3, and the like.

The wall member 29 is not limited to the one that defines the opening width of the guide groove 28.
