Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cover device that closes a notch at the lower end of a hollow pull bar integrally formed on the indoor side of an interior stile.

In order to ensure safety even when a sliding door running on a rail is exposed to outdoor wind pressure, a model is provided in which a hollow reinforcing member is integrally formed along the vertical direction on the indoor side surface of the inner stile.

Moreover, it can also be conveniently used as a so-called pull bar, which is used to open and close a sliding door.

However, in order to allow such an inner dowel stile to run freely on the rail, it is necessary to cut out the lower end of the pull bar at least according to the height of the weir wall.

Moreover, an extra notch is required to take account of the unevenness of the sill or floor surface and the installation and removal of the sliding door, so there is always a gap of 10 mm or more between the sill or the lower end of the pull bar.

If left as is, there is a risk that your toes will get caught in this gap while you are running through the sliding door, causing unexpected injury from the sharp edges of the notch. This is extremely dangerous, especially for young children. It could happen.

Also, from the appearance point of view, it would be bad to leave the notch intact.

When attaching a cover to this dangerous notch, a common method is to provide a through hole in the side of the interior of the interior stile and then secure the bent part to one side edge of the cover with screws.

However, with this method, it is necessary to drill holes in each stile, and the positions of the screw holes must be accurate in order to fit the cover tightly against the notched surface.In addition, the vibration of the sliding door while driving is required. This may cause the screws to loosen.

This invention was made to solve the above-mentioned drawbacks.
To provide a cover device for a pull bar of a sliding door stile that can be easily attached to the stile without any processing and does not loosen even after long-term use.

This purpose consists of at least a wedge piece having tapered surfaces disposed facing each other and having a threaded hole formed in the center, and as the tapered surface of this wedge piece moves downward, the wedge piece is pressed against the inner wall of the pull bar. a protrusion disposed opposite to each other so that This is achieved by rotating the screw to tighten the screw, which is inserted into a screw insertion hole in the lid of the cover piece and screwed into the screw hole in the wedge piece.

According to the present invention, since the pull bar notch surface is covered with a lid portion having approximately the same area as the pull bar notch surface, the sharp cut is hidden and it is safe to open and close the sliding door freely without damaging the appearance. .

In addition, the cover piece is fixed by the wedge action by simply inserting the wedge piece and the cover piece into the hollow part of the pull bar while overlapping and turning the screw, so it can be done extremely easily without needing to machine the stile. Since a large frictional force is obtained by the wedge action, the attachment of the cover piece will not loosen over a long period of time.

The present invention will be described in detail below with reference to the illustrated embodiments.

Fig. 1 shows an interior stile with a puller to which the cover device of the present invention is applied. The inner wall of the portion 2 is provided with ribs 3a and 3b.

Further, a side wall 5 having an opening 4 into which a glass or the like is inserted is formed in the rail running direction (in this case, on the right side in the figure).

Fig. 2 is a side view of Fig. 1 viewed from the direction of arrow A, and shows that the cutout length L (see Fig. 1) at the lower end of the puller 3 of the stile 1 running on the rail 7 of the window lower frame 6 is This shows that it corresponds to the height of wall 8.

The gap l between the sill and the lower end 9 of the pull bar (see Figure 1) is lQ.
mm, and the edge 9a of the notch is generally sharp.

Reference numeral 10 indicates a cover piece of the cover device of the present invention.

Figure 3a shows the wedge piece 11. The figure shows the cover piece 10, and the figure C shows the wedge 12. The wedge piece 11 has a screw hole 11a formed in the center, and four sides 11b, 11b.
, 11c, and llc form tapered surfaces that become narrower toward the bottom in the figure.

The wedge piece 11 is a molded material made of hard synthetic resin with two hollowed out parts 1.
It has 1 d.

The cover piece 10 (see the same figure) is a semi-hard synthetic resin molded material and has four independent protrusions 10 b and 10 on the top surface of the lid part 10 a.
b, 10c, lQc are integrally formed, and these four protrusions 10b, 10b, 10C, 10C are the wedge piece 1
1 tapered surface 11b.

Due to the collision of 11 b , 11 C, and 11 C, the free ends are bent outward, respectively.

A screw insertion hole 10d is formed in the center of the lid part 10a, and a lower part 10e of the hole 10d forms a tapered surface, and the screw 1
It has the same angle as the head tapered surface 12a of No. 2 (see C in the same figure).

A notched cylindrical wall 10 f is formed in the upper center of the lid portion 10 a, and the inner diameter portion of the cylindrical wall 10 f loosely fits the outer diameter portion of the incomplete cylindrical portion 11 e of the wedge piece 11 .

One end of the lid part 10a is bent at a right angle and extends to form the lower plate 1.
The lower end of the lower plate 10g forms a projecting edge 10h.

Note that the dimensions between the outer surfaces of the projections 10b, 10b and 10C, 10C of the lid 10a are the same as the inner wall W of the pull bar.
and H dimensions are set slightly shorter.

Next, a method for assembling each component described above will be explained.

That is, when the wedge piece 11 is placed on the upper part of the cover piece 10, the incomplete cylindrical part 11e at the center of the wedge piece 11 is loosely fitted into the cutout cylindrical wall 10f of the cover piece 10, and the tapered surface 11b of the wedge piece 11 is inserted into the cutout cylindrical wall 10f. , 11b... are lightly abutted against the inner ends of the projections 10b, 10b... of the cover piece 10.

In this state, if the screw 12 is inserted from the lower part of the lid part 10a and rotated in the direction of tightening, the screw hole 11 of the wedge piece 11 will open.
It enters a screwed state with a.

Therefore, the cover device with these three points lightly assembled was installed as the first
Insert the pull bar lower end 9 shown in the figure from below, and cover the lid part 10.
If the screw 12 continues to be rotated in the direction to tighten the screw 12 again while a is in contact with the lower end 9 of the pull bar, the wedge piece 11 will move downward,
Therefore, the tapered surfaces 11 b, 11 b, . . . bend the projections 10 b, 10 b, .

In this way, the protrusions 10 b , 10 b . . . of the cover pieces 10 are pressed against the inner wall of the pull bar with strong pressure due to the wedge action, so that the cover device is firmly fixed to the lower end of the pull bar.

In addition, since the lower plate 10g of the lid part 10a comes into contact with the interior side surface 1a of the inner matching stile 1, the pull bar notch trace 9b,
9b is hidden.

The lower edge 10b of the lower plate 10g is a reinforcing material that prevents deformation of the lower plate 10g.

FIG. 4 shows another type of cover piece of the cover device according to the present invention, in which three side edges of the lid portion 13a of the cover piece 13 are formed with projecting edges 13b upwardly.

This protruding edge portion 13b surrounds the outer periphery of the flat end portion of the puller 3 shown in FIG. 1, and is thereby used for positioning and also has the effect of increasing the aesthetic appearance.

In this case, since the protrusion 13b positions the protrusion 13
There is only one pair of C and 13C facing each other.
