Description

[Detailed explanation of the invention] This invention has an auxiliary foot on the inner surface of the square protrusion so that it can be attached either by screwing the upper and lower fins or by screwing the center part of the upper surface of the square protrusion. , and a side arm that is in a straight line with the auxiliary leg on the upper surface of the protrusion and has a hook at the tip, and a side arm that extends the leg at the lower end of the protrusion and has a hook at the tip. The main body is separate from the rectangular air body, with hooks protruding from the top and bottom of the outer surface, a sliding groove with a wind pressure prevention hook on one side of the internal top surface, a track on both sides of the bottom surface, and a dust trap in the center. This invention relates to a rail for a half-folding storm door in which a door roller holder provided with a groove is integrally connected with each hook part and fixed with a screw.

In conventional house structures, the storm door rail, which allows the shutter to be placed inside the door pocket, could be installed by screwing the upper and lower fins of the door holder, which had sliding grooves, to the window frame. However, due to changes in the structure of houses, windows have become larger and emphasis has been placed on ventilation and lighting, and now the door pockets have been removed and used as windows and storm shutters, so the window frames are also closer to the roof tiles. Or it has become necessary to install it close to a balcony or terrace. Therefore, when attaching this storm door rail to a window frame, there are cases where the upper and lower fins can be screwed together, and cases where only the upper fin contacts the window frame and the lower fin comes off from the window frame. There are cases where the window frame is close to roof tiles, balconies, or terraces and cannot be secured with screws. As a means for such cases, auxiliary metal fittings were used to attach the device, but the fixing force was weak and it was not reliable.

Furthermore, when the shutters are closed during strong winds or rainstorms, the wind pressure causes the shutters to fly out of the rails, causing wind pressure noise and causing the rails to partially bend.

In this case, the mounting body and the door roller holder can be separated, and it can be mounted by screwing the upper and lower fins of the mounting body, or by screwing the center part of the top surface of the square protrusion, so it can be attached to the window frame. It can be installed even if there are roof tiles or a balcony or terrace close to each other, and if the wind pressure prevention hook of the door roller holder is inserted into the sliding plate connected to the door roller support rod and the shutter is slid, strong winds can be prevented. Also, it can prevent problems caused by wind pressure in the event of a rainstorm.

To explain this with an example, an auxiliary leg 6 having the same length as the upper and lower transverse legs 4 and 5 is provided on the inner surface of a rectangular protruding part 3 having fins 1 and 2 on the upper and lower parts. A horizontal arm 8 with a hook 7 at the tip
, extend the lower side leg 5 horizontally, and attach the hook part 9 at the tip.
A mounting main body 11 is formed by a side arm 10 provided with a side arm 10, and hook portions 12, 13 are provided separately, protruding from the upper and lower portions of the outer surface of the rectangular hollow body.
A wind pressure prevention hook 15 is formed on the groove edge 14 continuous to the inner hook portion 12 of No. 3, and a groove edge 16 is formed opposite to the groove edge 14.
A sliding groove 19 is formed by providing groove edges 17 and 18 facing each other below the sliding groove 19, and tracks 20 and 21 are provided on both sides of the inner bottom surface of the cavity adjacent to the lower side of the sliding groove 19.
A garbage dropping groove 22 is provided in the center to form a door roller holder 23, and the hook portions 12, 13 of the door roller holder 23 are engaged with the hook portions 7, 9 of the mounting body 11 to form an integral body. , In the figure, 24, 25, 26 are window frames, 27 is a roof, 28, 29, 30 are mounting screws,
31 is a pressure screw, 32 is a stand frame, 33 is a shutter support rod, 34 and 35 are door wheels, 36 is a sliding plate, and 37
is a broom for removing trash attached to the bottom of the shutter support rod.

The present invention is constructed as described above, and the mounting body 11 and the door roller holder 23 are connected to the hook portions 7 and 9.
The mounting body 11 is integrated by engaging the hook parts 12 and 13, and the mounting body 11 is attached to the window frame 25 or 26.
Depending on the width of the roof, veranda, or terrace, the upper and lower fins 1 and 2 are screwed together, or the central part of the upper surface of the protrusion 3 is screwed. When the upper and lower fins 1 and 2 are screwed to the window frame 25, the auxiliary feet 6 are also attached to the window frame 2.
5, and when the protruding part 3 is screwed, the upper fin 1 and the auxiliary foot 6 are attached to the window frame 2, as in the case of the window frame 26.
6, but the lower fin 2 separates. In either case, screwing can be easily done and the main body 11 can be strongly attached. When the door roller holder 23 is engaged, the two become an integral part, forming a rail for freely opening and closing the folding shutter.

In this case, the upper and lower fins 1 and 2 are screwed together, and the protrusion 3 is screwed together, so the screw holes are not pre-drilled but are opened according to the situation at the site. In addition, after the door roller holder 23 is engaged with the main body 11 to form an integral body, screw holes are drilled at appropriate intervals and screwed to secure the hooks 7 and 12 even more securely, since they will not separate. be.

Also, a garbage dropping groove 22 provided on the bottom of the door wheel holder 23
has a rectangular shape with a constant width with both sides vertical, and the tracks 20 and 21 are inclined toward the dirt receiving groove 22, so that dirt that has entered the tracks 20 and 21 through the opening of the upper sliding groove 19. Every time the shutters are opened or closed, the door wheels 34 and 35 of the shutter support rod 33 attached to the stile 32 slide on the tracks 20 and 21, causing the tracks 20 and 21 to vibrate, so the garbage is naturally collected. It falls into the falling groove 22. In order to discharge the fallen garbage, an outlet of an appropriate size is bored in the middle part and both ends of the inner bottom surface of the garbage dropping groove 22, and in order to sweep and discharge the garbage, an outlet of an appropriate size is provided in the groove. A matching broom 37 is inserted and the upper end surface is attached to the lower surface of the shutter support rod 33, and the broom 37 automatically sweeps away the dirt in the groove every time the door wheels 34, 35 slide. and discharge it to the outside from the outlet.

The present invention is installed on the upper and lower window frames 24 and 25 facing each other, that is, the lower window frame 25 is installed with the sliding groove 19 of the door roller holder 23 facing upward, and the upper window frame 24 is installed with the sliding groove 19 facing upward. Although it is installed with the sliding groove 19 facing downward, the door roller 3 is placed on the tracks 20 and 21 of the upper window frame 24.
4,35 cannot be inserted. The sliding plate 36 is fitted into the sliding grooves 19, 19 of the upper and lower door roller holders 23, 23 to prevent the shutter from moving violently due to wind pressure.

As described above, the present invention is a rail for folding shutters of windows that is compatible with modern architectural structures, and has excellent effects.
