Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a door running guide device applied to a folding door or a partition panel, and is particularly characterized by means for preventing the lower runner from coming off from the lower guide rail. has.

[Conventional technology]

For folding doors, etc., the weight of the door is supported by an upper runner against the upper guide rail, and a lower runner is provided to guide the door along the lower guide rail in order to prevent the door from wobbling when opening and closing. ing.

For example, as a conventional lower launch,
As seen in Japanese Patent No. 72 and Japanese Utility Model Publication No. 60-3910, there are roller-less or bottle structures that rotate around a vertical axis. There is another one constructed as a slide block as seen in Japanese Utility Model Publication No. 10384/1984.

[Problem to be solved by the invention]

Lower runners with a roller structure or bottle structure have the disadvantage that they are easily removed from the guide rail when the door swings in the longitudinal direction of the rail around the upper runner, making it difficult to remove the runner, especially when suddenly operating the door. Easy to come off.

In this respect, the slide block structure is fixedly guided to the guide rail so that it cannot be removed, so even if a sudden operation is performed, the lower runner will not be removed from the guide rail. However, compared to a lower launch with a roller structure, the frictional resistance during opening/closing movement is greater and the operation is less nimble. Furthermore, it is necessary to assemble the lower runner into the guide rail in advance of assembling the door, which is troublesome to assemble. Although it is possible to provide a notch in a part of the guide rail and later assemble the lower runner from this notch, it is unsightly and tends to get stuck at the notch.9 The present invention solves the drawbacks of such conventional lower runners. The purpose of this invention is to provide a door traveling guide device equipped with a lower runner that does not fall off from the lower guide rail and can be easily opened and closed.

Another object of the present invention is that the lower runner can be easily assembled to the guide rail in the same manner as in the conventional roller structure;
The goal is to improve workability on site.

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

In FIGS. 1 and 4, the lower runner 6 includes a runner main body 31 which is a plastic molded product, a pair of rollers 32 arranged before and after the runner main body 31, a horizontal shaft 33 that rotatably supports the rollers 32, and a runner main body 31 which is a plastic molded product. It consists of a mounting plate 34 and a hinge 35 for mounting the main body 31 on the door 3. This mounting plate 34 is one side of the mounting means in the present invention.

The runner main body 31 is formed into a rectangular box shape with a thin front and rear thickness, and has a groove 36 opening toward the upper surface inside thereof. By inserting the mounting plate 34 into this groove 36 and passing the horizontal shaft 33 through the long hole 37 in the vertical direction connected to the plate surface, the runner body 31 can be moved vertically and downwardly relative to the mounting plate 34. Connect it to prevent it from being removed. As shown in FIG. 2, there are 1. Spring groove 38
The runner main body 31 is pushed down toward the lower guide rail 8 by a compression coil spring 39 mounted in the spring groove 38.

The roller 32 has a flange 40 at its inner end, and the flange 40 is supported by a receiving surface 30 so that its movement is 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, but when an upward force is applied to the roller 32, it easily rolls over the receiving surface 30.
Take off from the train. In order to prevent this, the runner body 31 is pressed downward by the spring 39, and an engaging body 41 is provided at the lower end of the runner body 31.

In FIGS. 1 and 4, the engaging body 41 is formed to protrude backward from the rear edge of the lower end of the runner body 31, and is engaged with the lower end of the runner body 31 in the guide groove 28 of the lower guide rail 8. The assembly 41 wraps around below the wall member 29 in a non-contact manner, and when the roller 32 tries to lift up from the receiving surface 30, the engaging body 41 abuts and engages with the wall member 29, The runner main body 31 is prevented from coming out from the guide groove 28.

A recess 42 is cut out on the front edge side of the lower end of the runner body 31 so as to correspond to the engaging body 41 .

The amount of depression of this recessed portion 42 approximately corresponds to the amount of rearward protrusion of the engaging body 41. That is, as shown in FIG. 4, the engaging body 41 is provided with a notch in the middle between the left and right sides of the runner body 31, and the recess 42 is formed over the entire width of the runner body 31 in the left and right sides.

In FIG. 7, when the opening width B of the guide groove 28 is used as a reference, the longitudinal width of the runner body 31 is set smaller than the opening width B. Furthermore, the longitudinal distance C between the protruding end of the engaging body 41 and the recess 42 is set to be slightly smaller than the opening width B of the guide 'a28.

By setting the dimensions in this way, the lower end of the runner body 31 can be inserted into the guide groove 28 using the recess 42 while tilting the entire lower runner 6 with the engaging body 41 entering the guide groove 28 first. After this, if the runner body 31 is returned to its normal standing position and the rollers 32 are placed on the receiving surface 30, the lower runner 6 can be easily assembled to the lower guide rail 8.

At this time, the recess 42 functions so that the engaging body 41 can wrap around below the wall member 29 without contacting and interfering with the wall member 29. In other words, the lower runner 6 can be easily assembled later with the lower guide rail 8 installed.

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

In FIG. 4, the T number 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 fixed to one hinge plate 17 by caulking. , fix the other hinge plate 16 to the door with screws. At this time, the center axis of the hinge shaft 18 is made to coincide with the upper and lower T numbers 11 and 35.

According to the lower runner 6 configured as above, when the folding door 2 is opened or closed by pushing or pulling one door 3 as shown in FIG. 6, the roller 32 rolls on the lower guide rail 8. Since the door 3 is moved by moving, opening and closing operations can be performed easily.

The roller 32 has its flange 40 restricted to move in the front-back direction by the receiving surface 30 on the rail, and the front and rear surfaces 31a and 31b of the runner body 31 are close to the wall wipers 29 and 29, so that the door does not close when running. 3 does not wobble back and forth.

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

In particular, when the folding door 2 is folded outward (forward) as shown in FIG. 6, the lower end of each door 3 tends to tilt diagonally backward, but the engaging body 41 protrudes from the rear edge of the lower end of the runner body 31. Because of this, engagement with the wall member 29 effectively prevents the lower runner 6 from coming off 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 majority of the elongated hole 37, the runner body 31 will spring as the roller 32 lifts and separates. 39, the roller 32 can be prevented from separating from the receiving surface 30, and the engaging body 41 mentioned above can be prevented from moving away from the receiving surface 30.
Combined with the tilting prevention operation, falling of the lower runner 6 can be more reliably prevented.

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

It consists of a spring 39 that presses and biases the runner main body 31 against the lower guide rail 8 via the support shaft 44.

Since the partition panel 3a swings back and forth around the support shaft 44 when opening and closing, the front and back width of the runner body 31 is made smaller than the inner 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 No. 1 35 is changed. In this case, the shape of the pair of hinge plates 16 and 17 in plan view is deformed into a rank shape that can be overlapped with each other, and one of the hinge plates 16 is embedded and fixed in the wall of the door 3. In this way, when the lower runner 6 and the door 3 are connected with the crank-shaped hinge plates 16 and 17,
By positioning the hinge shaft 18 on the outside of the lower runner 6, the side edge of the opening frame 1a can be completely covered with the door 3, and the external appearance of the second folding door when it is fully closed is improved. It is advantageous for
