DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door sill with a sliding door which supports a sliding door via a sliding door and guides the sliding door when the sliding door is opened and closed.

[0002]

2. Description of the Related Art Conventionally, as a sliding door sill with a sliding door which supports a sliding door via a sliding door and guides the sliding door when the sliding door is opened and closed, for example, as shown in FIG. The wheel 9e of a door wheel 9 (called an R door wheel), which is attached to the lower surface of the sliding door 8 and whose peripheral portion is formed in an arc-shaped cross section, is mounted on the groove 1a (called a V groove). The one configured to be always guided along the center of the groove 1a is used.

[0003]

However, in the conventional example, since the groove 1a is formed in a V-shaped cross section, there is a problem that dust easily accumulates and it is difficult to remove the dust. As a countermeasure, in order to lift dust accumulated in the groove 1a to the height of the upper surface of the groove-shaped rail 1 and to guide the dust easily, a sweep-out piece P shown in FIG. 9 is fitted to the end of the groove 1a. Although it is worn, the root cause that dust easily accumulates has not been removed.

Further, the groove-shaped rail 1 lacks flexibility and elasticity and has poor cushioning properties, and almost has an effect of alleviating and damping all impacts and vibrations received by the groove-shaped rail 1 from the sliding door 8 through the door roller 9. However, there is a problem that the impact / vibration sound is large when the sliding door 8 is opened / closed or when the wind is strong. If dust accumulates, the impact and vibration noise during opening and closing increases. In addition, sliding door 8
In addition, if the door roller 9 receives a force from the horizontal direction for some reason, there is a possibility that the sliding door 8 together with the door roller 9 may come off from the grooved rail 1 and fall down.

[0005] It is an object of the present invention to prevent dust from being collected, to remove semi-automatically even if collected, to reduce the impact and vibration noise when opening and closing a sliding door or when the wind is strong, to be light, Another object of the present invention is to provide a sliding door sill with a door roller, which makes it difficult for the sliding door to be detached from the groove-shaped rail and falls.

[0006]

To achieve the above object, a sliding door sill with a door wheel according to the present invention is provided fixed along a bottom surface (15) of a groove of a grooved rail (10). The lower magnetic strip (20) having at least the upper surface thereof magnetized, and the lower magnetic strip (2)
0) is fitted along the groove of the groove-shaped rail (10) such that the lower surface faces the upper surface at regular intervals.
An upper magnetic strip (30) having flexibility and at least a lower surface of the upper magnetic strip (30).
(0, 30) have the same polarity on opposing surfaces, and among the upper magnetic strips (30), a door wheel (90) attached to the lower surface of the sliding door (80) is present above. The portion on which the load of the sliding door (80) is applied is curved downward along the lower surface of the door roller (90) to approach the lower magnetic strip (20), but the door roller (90) does not exist above. , The part where the load of the sliding door (80) is not applied is the lower magnetic strip (2).
0), the upper surface (35) is configured to be flush with the upper surface of the grooved rail (10).

According to a second aspect of the present invention, the groove of the groove-shaped rail (10) is formed in an inverted T-shaped cross section, and the lower wide portion (11) is formed.
And a flat plate having a narrow portion (12) communicating with the upper opening (16) on the upper side, and the lower magnetic strip (20) fixedly provided along the bottom surface (15) of the wide portion (11). The upper magnetic strip (30) is capable of ascending and descending a narrow portion (12) having vertical wall surfaces on both sides on a base (31) facing the lower magnetic strip (20) on the lower side. The sliding door sill with a door wheel according to claim 1, wherein the upwardly protruding portions (32) are integrally joined.

According to a third aspect of the present invention, the door wheel includes the wheel (95).
The sliding door (90) having a peripheral surface formed in a cylindrical shape, for example, a flat sliding door, the sliding door with a sliding door according to claim 1 or 2, characterized in that:

It should be noted that the sliding doors include not only partitions of each room but also any sliding doors such as aluminum sashes, sliding doors, and closets, and the present invention can be applied to these sliding doors. Symbols in parentheses described in the means for solving the above problems correspond to the symbols described in the drawings and the embodiments of the invention described later.

According to the first or second aspect of the present invention, the upper magnetic strip is flexible, and among them, most of the lower part where the door wheel does not exist and the load of the sliding door is not applied is the lower side. As the magnetic strip repels, it floats up, separates from the lower magnetic strip, and its upper surface is flush with the upper surface of the grooved rail, so that dust does not collect. In addition, the extremely limited part where the door roller is located above and on which the load of the sliding door is applied via the door roller is curved downward along the lower surface of the door roller, thereby causing a depression, but the door roller moves to another part. Then, the recessed portion floats due to the repulsion of the lower magnetic strip, returns to its original position, and its upper surface is flush with the upper surface of the grooved rail. Therefore, the dust that has accumulated in that portion also floats up and is semi-automatically removed or extremely easily removed.

Since the upper magnetic strip is flexible and repelled by the lower magnetic strip, the upper magnetic strip has a cushioning property like a spring. Since it has the effect of alleviating and attenuating all impacts and vibrations received, it is possible to minimize the impact and vibration noise when opening and closing the sliding door and when the wind is strong.

[0012] According to the second aspect of the present invention, even if the door wheel and the sliding door may receive a force in the horizontal direction, the door wheel that has sunk downward has a narrow portion having vertical wall surfaces on both sides. Since the movement is reliably prevented, the accident that the sliding door comes off the grooved rail together with the door roller and falls down is also prevented.

According to the third aspect of the present invention, the first aspect is provided.
Or, in addition to the function and effect of the invention described in 2, since the peripheral surface of the wheel is formed in a cylindrical shape like a flat door car, even if it floats for some reason, it is difficult to come off, so the sliding door is There is no accident of falling.

The rolling friction and other frictional resistance of the door roller are not different from those of the conventional example, and the opening and closing of the sliding door is light as in the conventional example.

[0015]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a vertical sectional view of a sliding door sill with a door roller according to an embodiment of the present invention, and FIG.
1 is an AA cross-sectional view of FIG. 1, FIG. 3 is a BB cross-sectional view of FIG. 1, and FIG. 4 is an exploded cross-sectional view showing a main part of FIG.

In the sliding door sill with a door roller according to the embodiment of the present invention, a flat lower magnetic strip 20 having at least an upper surface magnetized is fixed along the bottom surface 15 of the groove of the grooved rail 10. It is provided. The upper magnetic strip 30 is formed along the groove of the groove-shaped rail 10 so that the lower face faces the upper face of the lower magnetic strip 20 at a fixed interval.
Is inserted.

The upper magnetic strip 30 has magnetism at least on its lower surface and has flexibility. Also, both magnetic strips 20 and 30 are kneaded with magnetic powder in rubber (plastic such as urethane may be used instead of rubber).
Molded and vulcanized, the opposite surfaces have the same polarity, and are configured to operate as follows.

That is, in the upper magnetic strip 30, a door wheel 90 attached to the lower surface of the sliding door 80 is located above, and a portion of the upper magnetic strip 30 to which the load of the sliding door 80 is applied via the door wheel 90 extends along the lower surface of the door wheel 90. The lower magnetic strip 20
Close to. Conversely, the portion where the door roller 90 does not exist above and the load of the sliding door 80 is not applied floats up, separates from the lower magnetic strip 20, and the magnetic force is applied so that the upper surface 35 is flush with the upper surface of the grooved rail 10. Is set.

More specifically, the groove portion of the groove-shaped rail 10 fitted and fixed to the sill member is formed in an inverted T-shaped cross section, and has a narrow width communicating with the lower wide portion 11 and the upper upper opening portion 16. It has a part 12. Moreover, the lower magnetic strip 20 is
It is a flat plate and is provided fixed along the bottom surface 15 of the wide portion 11. On the other hand, the upper magnetic strip 30
The upper convex part 32 is integrally connected to the base 31 facing the lower magnetic strip 20 on the lower side. In addition, the convex part 32 is formed so that the narrow part 12 which has a vertical wall surface on both sides can be moved up and down. Also, even when the upper magnetic strip 30 floats, the base 31 is stopped at the step between the wide portion 11 and the narrow portion 12 so that the upper surface thereof is flush with the upper surface of the groove-shaped rail 10. The height of the convex portion 32 is set in.

Referring to FIGS. 5 and 6, a door 92 is integrally connected to a mounting seat 91 to be mounted on the sliding door 8, and a wheel 95 is mounted on the bearing 92. Moreover, the peripheral surface of the wheel 95 is formed in a columnar shape (referred to as a flat door car).

In the sliding door sill with a door wheel constructed as described above, the following conditions are satisfied: the height of the sliding door 80 is 1,820 mm, the width is 850 mm, and the weight is 15 k.
g, the diameter of the wheel 95 of the door roller 90 = 36 mm, the width =
The dimension of the groove-shaped rail 10, the upper magnetic strip 30, and the lower magnetic strip 20 is L1 = 5 as shown in FIG.
mm, L2 = 3 mm, L3 = 3 mm, L4 = 5 mm, L
The results of experiments on the operation with 5 = 6 mm are shown.

According to this, the rolling friction and other frictional resistance of the door roller 90 are not different from the conventional example, and the opening and closing of the sliding door 80 is light as in the conventional example. In addition, the upper magnetic strip 30 is flexible, and the door roller 90 does not exist above, and the sliding door 80
Most of the portion where no load is applied is lifted by the repulsion of the lower magnetic strip 20, separated from the lower magnetic strip 20, the upper surface 35 is flush with the upper surface of the grooved rail 10, and dust collects. There was no. In addition, the extremely limited portion where the door stroller 90 is located above and the load of the sliding door 80 is applied through the door stroller 90 is curved downward along the lower surface of the door stroller 90, so that a recess is generated. When it moved to another part, it floated by the repulsion of the lower magnetic strip 20, returned to its original position, and the upper surface 35 was flush with the upper surface of the grooved rail 10.
Therefore, the dust that has accumulated in that portion also floats up and is removed semi-automatically or very easily.

Moreover, since the upper magnetic strip 20 is flexible and repelled by the lower magnetic strip 20, the upper magnetic strip 20 has a cushioning property like a spring. This has the effect of alleviating and attenuating all impacts and vibrations received by the grooved rail 10, and the impact and vibration noise when opening and closing the sliding door 80 is extremely small, and is almost unnoticeable. In addition, even when the wind was strong, the sound was smaller than in the conventional example.

In addition, even if a horizontal force is applied to the door wheel 90 together with the sliding door 80, the door wheel 90 that has sunk downward is surely prevented from moving by the narrow portion 12 having vertical wall surfaces on both sides. The sliding door 80 came off the grooved rail 10 together with the door roller 90, and did not fall. Especially wheels 95
Is formed in a cylindrical shape, so that the sliding door 80 hardly comes off even if it floats up for some reason, and the accident that the sliding door 80 falls down does not occur.

In the embodiment of the present invention, the sliding door 80 is used.
Is shown as an example of a partition for each room, but it can be applied to any sliding door such as an aluminum sash, a sliding door, and a closet. FIG. 7 shows an application to a sliding door 98 of a closet, in which a sliding door 99 that rotates in the horizontal direction is fixed to the sliding door 98. Even with this configuration, the door wheel 99 does not exist above and the sliding door 9
Most of the parts where the load of 8 is not applied are
Of the lower magnetic strip 20 fixed to the bottom surface 115 of the grooved rail, floats up, separates from the lower magnetic strip 20, and the upper surface 35 is flush with the upper surface of the grooved rail 100, so that dust does not collect. Was. In addition, a door wheel 99 is present above, and the door wheel 9
An extremely limited portion on which the load of the sliding door 98 is applied via the lower portion 9 is curved downward along the lower surface of the door roller 99, so that a recess is formed. However, when the door roller 99 moves to another portion, the lower magnetic strip is moved. After being repelled by 20, he returned and returned to the upper surface 3
5 was flush with the upper surface of the grooved rail 100. Therefore,
Dust that had accumulated on that portion also floated up and was removed semi-automatically or was very easy to remove. The groove-shaped rail 100 has a lower wide portion 111 and a narrow portion 112 communicating with the upper opening 116 on the upper side.

[0026]

As described above, according to the first or second aspect of the present invention, most of the lower magnetic strip has an upper surface flush with the upper surface of the grooved rail, so that dust is collected. There is no. In addition, even if the door roller moves to another part, even if the door roller moves to another part, even if the door roller is located at the upper part, the upper surface is flush with the upper surface of the grooved rail. Can also be lifted and removed semi-automatically or very easily. Furthermore, even if the door wheel may receive a horizontal force with the sliding door, the door wheel is securely prevented from moving by the narrow portion of the grooved rail, so that the sliding door comes off the grooved rail together with the door wheel and falls down. Accidents are also prevented. The rolling friction and other frictional resistance of the door roller are not different from the conventional example, and the opening and closing of the sliding door is light as in the conventional example.

The upper magnetic strip is flexible and has a repulsion from the lower magnetic strip, so it has a cushioning property like a spring, so that the grooved rail can be moved from the sliding door through the door roller. Has the function of alleviating and attenuating all impacts and vibrations received by the door, so that the impact and vibration noise when the sliding door is opened and closed or when the wind is strong can be minimized.

In particular, according to the invention described in claim 2, even if the door wheel and the sliding door may receive a force in the horizontal direction, the door wheel sinking downward is formed by a narrow portion having vertical wall surfaces on both sides. Since the movement is reliably prevented, the accident that the sliding door comes off the grooved rail together with the door roller and falls down is also prevented.

According to the third aspect of the invention, in addition to the effects of the first or second aspect, the wheel is levitated for some reason because the peripheral surface of the wheel is formed in a cylindrical shape. Even so, it is hard to come off and there is no accident that the sliding door falls.
