Description

[Detailed Description of the Invention] The present invention relates to a folding door having handle portions inside and outside of the middle crosspiece.

Conventionally, as shown in Fig. 5, there are structures in which openings are formed inside and outside of the middle crosspiece a of the folding door, and these are used as handles. Since the upper and lower ratios of b have to be shifted, the width of the middle crosspiece a becomes larger, and if you try to make the handle easier to hold, the opening
b has to be made wider, and in doing so, the width of the middle crosspiece has to be made even wider, which is undesirable from both cost and appearance standpoints.

Another conventional structure, as disclosed in Japanese Utility Model Application No. 53-145346, is a structure in which openings are formed inside and outside the middle crosspiece and a towel rack is attached to the inside opening. The disadvantage that the width of the middle crosspiece increases because the openings of the crossbars rub vertically has not been resolved.

The present invention solves the above-mentioned drawbacks, and is a folding door that has handles inside and outside the middle crosspiece, and it is possible to form easy-to-grip handles inside and outside the middle crosspiece without particularly increasing the width of the middle crosspiece. Moreover, it is an object of the present invention to provide a folding door equipped with a handle part that can be easily changed to either the left or right door.

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, a door frame 1 consists of an upper frame 2, a vertical frame 3+3, and a lower frame 4, and a folding door A is attached to this door frame 1.

The folding door A consists of left and right doors Al and A2 of the same structure and same dimensions, and each of the left and right doors A1 and A2 has an upper stile 5 and a vertical stile 6, 6'.
, a lower stile 7, a middle stile 8, etc., and the facing central vertical stile 6', 6' of both doors Al, A2 is a connecting member 9 (Fig. 3).
are foldably connected.

As shown in detail in FIG. 2, the middle crosspiece 8 has an opening 10 formed on the negative side extending over the entire length of the middle crosspiece, and a hanging piece 11 formed at the upper front end of the opening 10. , the opening 10 and the hanging piece 11 constitute a handle 12.

Further, the opening 1 is formed on the surface of the side wall 13 on the other side of the middle crosspiece 8.
A concave groove 14 is formed over the entire length of the middle crosspiece at a position opposite to 0.

When the middle frame 8 and the vertical frames 6, 6' of each door are assembled, the side wall 1 of the vertical frame 6, 6' faces the groove 14 of the middle frame 8.
A gap G corresponding to the cross-sectional area of the groove 14 is formed between 5, 15' and the side wall 13 of the middle crosspiece 8.

If necessary, the gap G can be enlarged by forming a notch in the side wall 15 at a location corresponding to the groove 14, and by forming a portion that slightly protrudes into the groove 15 at this location, the gap G can be increased. Can be made smaller.

As shown in FIGS. 3 and 4, the two handle mounting brackets 16, 16' have upper portions 17, 17' on opposite inner sides of each other.
The handle 18 is fitted into the recesses 17 and 17', and the screw 1 is inserted.
Screw holes 1 formed inside the handle 18 at 9 and 19'
8' from the outside of each handle mounting bracket 16, 16'.

As shown in FIG. 4, a recess is provided at the base end of the handle mounting bracket 16, and a mounting fitting 20 having a protrusion 20a projecting to the outside of the handle mounting bracket is fixed to this recess by screws 21.

The protrusion 20a has a shape that can be fitted into and removed from the gap G.

Although only the handle mounting bracket 16 side is shown in FIG. 4, the structure of the handle mounting bracket 16' side is also the same except for the cross-sectional shape of the vertical frame.

Further, the protrusion 20a of at least one of the mounting brackets 20 attached to the base ends of both handle mounting brackets) 16, 16' extends slightly toward the handle 18 side, that is, the side wall 15 side of the vertical stile 6. It is bent.

To assemble the handle 18 and handle mounting brackets 16, 16', fit both ends of the handle 18 into the inner recesses 17, 17' of the handle mounting bracket 16, 16-, and then attach the handle 18 to the handle mounting bracket i6, 16. After inserting the base end fitting 20 into the gap G, the handle 1:8 may be fixed with the screw F9.

To remove it, remove the screw 19, move the base end of the handle mounting bracket 16 in the direction of arrow 22, and remove the mounting bracket 20 from the gap G.

By slightly bending the protrusion 20a of the mounting bracket 20 as described above, the operation of inserting and removing it into the gap G can be easily performed without damaging the groove 14 of the middle crosspiece 8. , □ may have a shape parallel to the groove 14 without being bent.

Although the mounting bracket 20 is separate in the illustrated embodiment,
The empty part 20a may be formed integrally with the handle mounting bracket 16. When the rotating shaft 23 of the folding door A is on the left door A1 side as shown in FIG. 1, for example, the handle 18 is provided on the right door A2. , When opening on the left and right sides, the rotation axis will be on the right door A2 side.

In this case, it is necessary to change the handle 18 to the left door A1, but in that case, the position can be easily changed by simply removing the screw 19 of the handle as described above, without disassembling the door.

When the folding door A is folded, the left and right doors Al and A2 overlap each other, so the handle must not protrude from the surface where the left and right doors Al and A2 overlap (the bottom surface in FIG. 3).

Therefore, the handle portion 12 of this overlapping surface is constituted by the opening portion 10 and the hanging piece 11 so as not to protrude from the middle crosspiece 8.

As described above, according to the present invention, as described above, a handle portion consisting of an opening and a hanging piece is formed on one side of the middle crosspiece, and a groove is formed on the other side at a position corresponding to the opening. Since the protruding part of the handle mounting bracket is fitted into the gap formed by the groove and the side wall of the stile, the handle on the - side and the handle on the other side are provided at almost the same position, so that both the inside and outside sides are provided. Even though the handle is provided on the handle, the width of the middle crosspiece does not increase, and since the handle can be attached to the middle crosspiece by fitting it into the center crosspiece without screwing, it is extremely easy to install and remove, and it is easy to change the left and right hand. There is an effect that it can be done.
