Description

[Detailed description of the invention] This invention relates to a device for upper and lower guide rails for a folding screen door for hanging, and a folding screen door device for hanging, which allows the folding screen door to be attached to a door with a door closer. .

Conventionally, this type of hanging folding screen door has the disadvantage that the lateral dimension of the opening portion where the screen is attached is not necessarily a constant width, and therefore the installation adjustment of the upper and lower guide rails is very troublesome and time-consuming.

Furthermore, when attaching a folding screen door to a door equipped with a door closer, it is inconvenient to create a frame body to which an upper guide rail is attached, avoiding the door closer, and to install this frame body above the opening. Further, this mounting frame has various drawbacks such as difficulty in mounting it on a metal frame or concrete finish frame of the opening.

This invention is an improvement over such conventional drawbacks, and its main structure is that the upper and lower guide rails installed in the opening have a substantially rectangular cross section, and Each engagement groove is formed at the position where the engagement groove is to be formed. In addition, several stages of insertion grooves are formed adjacent to this engagement groove, and the pressing movable body and the holding body are pressed from both sides of this insertion groove with tightening screws, and the upper and lower guide rails are inserted into the opening. Crimp. Furthermore, an engagement groove is provided in the side wall of the upper guide rail into which the lower edge of the cover of the door closer is fitted, and the upper edge of the cover is fitted into and supported by a clamp in the opening.

Therefore, according to this invention, each guide rail can be easily installed above and below the opening without using screws, nails, etc., and can also be easily installed in metal or concrete openings. Furthermore, there is an excellent effect in that a folding screen door can be easily attached to a door that has a door closer.

Next, an embodiment of this invention will be described with reference to the drawings. A foldable screen door body 1 installed at the opening of a house entrance/exit has an upper guide rail 2 and a lower guide rail 3 installed above and below the opening. It can be folded up so that it can slide freely between the two. The upper and lower guide rails 2 and 3 are
Each has a substantially rectangular cross section, and engaging grooves 4 and 5 are formed at opposing positions to which the upper and lower sides of the screen door body 1 fit. At least a plurality of insertion grooves 6, 6 and 7, 7 are provided alongside the engagement grooves 4, 5.
has been formed. At the ends of the upper and lower guide rails 2 and 3 of the insertion grooves 6, 6 and 7, 7, there are horizontal insertion pieces 11 that press against the left and right side frames 27, 27 of the opening.
The pressure contact movable body 8 provided with the elastic body 9 and the pressing body 10 provided with the insertion piece 12 mounted with the elastic body 9 interposed therebetween are inserted and attached. Further, the other ends of the upper and lower guide rails 2 and 3 have a rough surface portion 15 on the pressure contact surface and an insertion portion 14 on the inside.
A fixed body 13 provided with is fitted. code 16
is a rough surface portion provided on the outside of the press-contact movable body 8. 17 is a tightening screw screwed into the pressing body 10. Next, reference numeral 18 designates a cover for the door check 25, which forms a bulge that does not hit even when the door check 25 operates, and also connects the lower end side 31 of the cover 18 to an engagement groove provided on the side wall of the upper guide rail 2. 2
Fits into 0. Further, an upper end side 32 provided on the upper edge of the cover 18 is structured to be inserted into a support 22 attached to an upper frame 26 or the like of the opening.

Further, downward insertion grooves 21, 21 are formed before and after the engagement groove 4 of the upper guide rail 2, and an insect-proof cover 19 is provided in the insertion grooves 21, 21 to prevent insects from entering through the gaps. The upper edge is fitted. Reference numeral 24 indicates various doors, and 28 indicates a floor surface.

The hanging folding screen door device of this invention is constructed as described above, so to explain its usage now, when the folding screen door 1 is installed on the indoor side of the door 24 at the entrance/exit opening, the door The upper guide rail 2 and the lower guide rail 3 are constructed on the side frames 27, 27 or the wall surface located on the left and right sides of the guide rail 24. As shown in FIG. 3, the upper and lower guide rails 2 and 3 are inserted into the insertion grooves 6 and 6 at the other end by abutting the fixed body 13 fitted at one end against the side frame 27. Press the movable body 8 with a screwdriver 30, adjust and tighten the tightening screw 17 screwed into the pressing body 10, and tighten the upper and lower guide rails 2 and 3 to the side frame 2 of the opening.
7 and 27. The screen door body is assembled between the upper and lower guide rails 2 and 3.

Next, the cover 18 of the door check is applied from the surface to the door check 25, the lower edge 31 of the lower edge of the cover 18 is fitted into the engagement groove 20, and the upper edge 32 is fixed to the upper frame 26 etc. The cover 18 is fixed by being inserted into the clamping tool 22 that has been provided.

As described above, the folding screen door according to this invention can be used for doorways with different widths of openings in each house.
It can be mounted by adjusting and pressing freely, and the means for doing so has the advantage of being easy to operate with a simple tightening screw.

Moreover, this invention can be easily attached to a door to which a door check is attached, and has the effect of solving the conventional inconvenience and costlessness of making and installing a separate mounting frame. The multiple insertion grooves provided in the upper and lower guide rails allow the pressure-welding movable body and the holding body to be securely inserted, and the pressure-welding movable body can also be used with screws, nails, etc. even in metal frames or concrete-finished frames. It has the convenient effect of being able to be freely extended and installed when not in use. By using the fitting groove provided on the side wall of the upper guide rail and the clamp attached to the upper frame, it can be installed on all entrances of doors with door checks, and is a practical product that can completely prevent insects. effective.
In addition, since engagement grooves are formed in opposing positions of the upper and lower guide rails, they reliably engage with the upper and lower parts of the screen door body, ensuring smooth sliding, and reliably preventing gaps between the top and bottom of the screen door body. It also has the effect of reliably achieving an insect repellent effect.
