However, when the track surface is flat as the threshold rail, the door roller also has a flat rolling surface corresponding to the track surface. When it rolls, it has a drawback that it easily rocks to the left and right, and the sliding door cannot be opened and closed smoothly.

Therefore, in order to solve this, as shown in FIG.
A sill rail C'having a substantially V-shaped track surface 1'is laid in the groove 90 'of the sill 9'to prevent rolling of the sliding door.

<Problems to be solved by the invention> However, in sliding doors, it is necessary to prevent the lower frame of the sliding door from contacting the track surface or the upper surface of the sill. Since it is necessary to separate them, there is a problem in that the sill rail C'has a gap between the lower frame of the sliding door and the sill 9 ', and light leaks from this gap.

The present invention has been made in view of the above problems, and provides a sill rail that can prevent rolling of the sliding door and prevent light from leaking from between the lower frame of the sliding door and the sill. With the goal.

<Means for Solving Problems> A sill rail according to the present invention for achieving the above-mentioned object has a door roller shape attached to a groove formed in the sill and guiding movement of a door roller attached to a sliding door. A sill rail having a corresponding track surface, and guide walls for guiding both ends of the door roller are formed on both sides in the width direction of the track surface, respectively. Recesses that house near the lower end of the frame are arranged in a staircase pattern.
Further, a collar portion that can be placed on the upper surface of the sill is continuously provided on both sides of the recess in the width direction.

<Operation> According to the sill rail having the above configuration, the guide walls are formed upright on both sides in the width direction of the track surface, and the recesses are continuously formed in a staircase pattern on the upper part of the guide wall. When the door roller is installed on the track surface, the recess can accommodate the vicinity of the lower end of the lower frame of the sliding door.

Further, when the sliding door is opened and closed, the door wheels can be rolled with the guide walls provided on both sides in the width direction of the track surface while guiding both ends of the door roller.

<Embodiment> An embodiment will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a perspective view showing an embodiment of a sill rail A according to the present invention, and FIG. 2 is a sectional view showing a state in which a sliding door 5 having a door roller 50 mounted thereon is placed on the sill rail A. . The sill rail A is made of a metal material such as aluminum integrally formed by extrusion, and its surface is anodized to enhance the texture. Also,
The sill rail A is fixed to a groove 90 of a predetermined depth formed in the sill 9 with a screw 8 as a fixing member.

A flat track surface 1 corresponding to the shape of the rolling surface of the door roller 50 is provided at the center position in the width direction of the sill rail A. The track surface 1 is slightly wider than the width of the door roller 50. Has been formed. Further, guide walls 12 for guiding both ends of the door roller 50 when the door roller 50 is moved are formed on both sides of the track surface 1 in the width direction. Furthermore, in the center of the orbital plane 1,
Insertion holes 10 for inserting the screws 8 are provided at predetermined intervals.

On the guide wall 12, a recess 2 having a width and a depth for accommodating the lower end vicinity 51 of the lower frame of the sliding door 5 is continuously provided in a stepwise manner. Further, on both sides in the width direction of the recess 2, a collar portion 3 that can be placed on the upper surface of the sill 9 is continuously provided, and the upper surface 30 of the collar portion 3 is formed in a gentle rounded shape over the upper surface of the sill 9. Has been done. The lower surface 31 of the collar portion 3 is formed flat so as to be in close contact with the upper surface of the sill 9.

More specifically, the recess 2 includes a side wall 21 that closes both side surfaces of the lower frame near the lower end of the lower frame of the sliding door 5, and a bottom face 20 that faces the lower frame of the lower frame with a predetermined gap therebetween. , Above bottom
20 is divided into left and right by the raceway surface 1. Also,
The recess 2 not only accommodates the lower frame of the sliding door 5 in a state of being floated from the bottom surface 20, but as shown in FIG. When installing 6, the lower frame of the sliding door 6 may be slid on the bottom surface 20 of the recess 2 directly. The raceway surface 1
Also, on the bottom surface 20 of the recess 2, a ridge 11 is formed in parallel with the opening / closing direction of the sliding doors 5, 6 to reduce the frictional resistance when the sliding doors 5, 6 are opened / closed.

The sill 9 is made of a known material such as wood or concrete.

The sill rail A can be attached to the sill 9 in any case of new construction or renovation construction. After forming a slightly deeper groove 90 in the sill 9 according to the height of the sill rail A, the sill Insert the rail A into this groove 90 and set the collar 3
It suffices to place on the upper surface of the threshold 9 and fix it with the screw 8. When installing the sliding door 5 with the door roller 50 installed, the door roller 5 may be placed on the track surface 1 of the threshold rail A (see FIG. 2). Also, a sliding door 6 without a door car
When installing, the lower frame of the sliding door 6 may be placed on the bottom surface 20 of the recess 2 (see FIG. 3). As described above, since the track surface 1 and the recess 2 are provided side by side, the sliding door 5 with the door roller 50 and the sliding door 6 without the door roller can be exchanged at any time according to the preference of the resident. You can

According to this embodiment, when the door roller 50 is installed on the track surface 1, the lower end vicinity 51 of the lower frame of the sliding door 5 is accommodated in the recess 2, so that it is provided between the lower frame of the sliding door 5 and the sill 9. The resulting gap can be closed by the side wall 21 of the recess 2 and light can be prevented from leaking from the gap.

Further, since the door roller 50 moves while being guided by the guide walls 12 at both ends of the track surface 1, it is possible to prevent the sliding door 5 from swinging left and right when opening and closing the sliding door 5.

Furthermore, since the upper surface 30 of the collar portion 3 is formed in a gentle rounded shape over the upper surface of the sill 9, when placed on the upper surface of the sill 9, there is a step near the boundary between the upper surface of the sill 9 and the collar portion 3. The pedestrian can be prevented from tripping over the threshold rail A.

In particular, even in the case of the sliding door 6 to which the door roller is not attached, it is possible to open and close the sliding door 6 by placing the lower frame on the bottom surface 20 of the recess 2 and rocking the bottom surface 20. Therefore, it is possible to deal with various sliding doors regardless of the presence or absence of the door roller, and it is possible to enhance the utility value as the compatible threshold rail A.

When the sill rail A is laid, the groove of the sill 9 is
By forming 90 slightly deeper, the sill rail A
Since the flange portion 3 holds the groove 90 so that it is slightly raised from the bottom portion of the groove 90, it is not necessary to finish the depth of the groove 90 uniformly, and the groove 90 may be roughly ground. Therefore, the sill rail A can be laid quickly and easily.

In addition, since the sill rail A is made of a metal material such as aluminum, even if the sill rail A is used for a long period of time, as shown in FIG. 8, a plastic slip tape B'is placed in the groove 90 'of the sill 9'. It is possible to prevent peeling, loosening, and the like that occur when pasted.

Besides, since the bottom surface 20 of the recess 2 is divided into two by the raceway surface 1, the contact area with the lower frame of the sliding door 6 can be reduced by the width of the raceway surface 1, and the friction when the sliding door 6 is opened and closed. The resistance can be reduced.

FIG. 4 is a sectional view of the threshold rail A showing another embodiment. Although the sill rail A for a sliding door has been described in the above embodiment, the sill rail A is
It can also be used for double sliding, that is, sliding doors.

FIG. 5 is a perspective view of a threshold rail A showing still another embodiment. In this embodiment, a point different from the above embodiment is that the ridges 11 are provided on the track surface 1 and the bottom surface 20 of the recess 2. This is a point not provided. In addition, by providing a single groove 13 (or a ridge) parallel to the opening / closing direction of the sliding door at the center of the raceway surface 1, it is possible to easily perform centering when the raceway hole 10 of the screw 8 is drilled. You can

FIG. 6 is a sectional view of a threshold rail A showing still another embodiment. This embodiment is different from the above-mentioned embodiment in that an elastic holding piece 4 is formed at a lower position facing the collar portion 3. The holding piece 4 has a sharp corner 40 at the upper end and
The lower side from 40 is inclined inward. That is, when the sill rail A is attached to the groove 90 of the sill 9, the holding piece 4 can be introduced into the groove 90 by elastically deforming, and after the introduction, the corner portion 40 of the holding piece 4 is inserted into the groove 90. The side wall of the groove 90 is held by the flange 3 and the holding piece 4 by being engaged with the stepped portion 91 formed on the side wall. Therefore, the sill rail A can be prevented from coming off, and it is not necessary to use a fixing member 8 such as a screw, and the sill rail A can be attached by pushing the sill rail A from above the groove 90 with one touch.

In the above embodiment, the rolling surface of the door roller 50 is flat, and the track surface 1 of the threshold rail A is also flat in correspondence with the shape of the door roller 5. The present invention is not limited to this, and for example, the track surface 1 can be implemented in any shape such as a substantially V shape in correspondence with various shapes of the door roller 50.

The sill rail A can also be formed by casting or forging using a material such as iron. In this case, in order to enhance the texture, the surface may be plated with zinc or chrome.

Besides, various design changes can be made without changing the gist of the invention, such as using a curl plug or a P-less anchor instead of the screw 8 as the fixing member.

<Effect of Device> As described above, according to the threshold rail according to the present invention, when the door roller is installed on the track surface, the lower frame of the lower door of the sliding door is accommodated in the recess to allow the lower frame of the sliding door to be accommodated. It is possible to prevent light from leaking from the gap between the threshold and the threshold.

In addition, the guide walls on both sides in the width direction of the track surface move the door roller while guiding both ends of the door roller, so it is possible to prevent the door roller from swinging left and right, and to open and close the sliding door smoothly. It has a practical effect that it can be performed.
