Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal shutter installed in an opening of a building, and more particularly to a lower closing device for an upper suspension horizontal shutter having a double door on the front and back sides.

[Prior Art] Conventionally, a top-hung horizontal pulling shutter has a large number of doors arranged side by side in a row, and a connecting frame is interposed between the doors so that the adjacent doors can freely rotate. A shutter main body that can be folded and opened freely is formed by connecting to the upper frame rail, while the lower end of the shutter body is inserted only in the lower frame groove rail that is opened slightly wider than the door thickness. I was letting.

[Problems to be Solved by the Invention] However, since the door body of such a conventional horizontal pull shutter has a single plate shape in which a blind panel such as a glass panel or an aluminum plate is held in a four-sided frame, it is possible to achieve both daylighting and crime prevention. There was a limit in improving sound insulation performance.

In order to improve the problems of the conventional horizontal pulling shutter, the present inventor double-arranges a plurality of left and right door bodies facing each other on the front and back surfaces, and appropriately holds various panels or pipe lattices on the front and back surfaces. We have completed a horizontal hanging shutter with a double door that can be pressed, but in this case, if the lower ends of both front and rear doors are directly inserted into the lower frame groove rails, the expected width of the lower frame will increase and the cost will rise. In addition, it is necessary to provide door pockets formed by digging the floor to the depth of the groove to open and close the shutter body on both front and back sides. By staying or by omitting the front side surface of the lower frame groove rail in the door pocket, problems such as rain and dust prevention will occur.

The present invention has been made in view of the above problems, and has a front and rear double door body and can be provided with various panels, pipe lattices, etc. on each side. (EN) Provided is a lower closing device for a horizontal hanging shutter having a double door body on the front and rear surfaces, which can keep the frame groove rail width relatively small to suppress the cost and sufficiently close the lower portion of the door body. The purpose is to

[Means for Solving the Problem] The present invention has been completed in accordance with the above-mentioned object, that is, the present invention has a plurality of left and right door bodies which are arranged in a double manner so as to face both sides of the front and rear surfaces, and the left and right ends of each door body The shutter body is formed by connecting the four parts to the four-door body connection frame common to the front and back surfaces and the two-door body connection frame for each of the front and back surfaces alternately and rotatably to fold the front and back surfaces in a separable manner. The main body is provided with a door roller or a sliding body at the upper end of the four-door body connection frame so that it can be hung and run on an upper frame rail, while a drooping fin is projected over substantially the entire lower end of the front or back side door body and A front and rear double door body characterized in that the fin is engaged in the groove rail of the lower frame, and the longitudinal end of the groove rail is cut off in the door pocket so that the hanging fin can be detached from the groove rail. The gist of the lower closing device of the horizontal suspension type pulling shutter with To do.

[Operation] As a result of the above, in the lower closing device for the horizontal hanging type horizontal shutter having the front and rear double doors according to the present invention, each of the front and rear doors is lifted via the door roller or the sliding member at the upper end of the four door connecting frame. While hanging on the frame rail, the hanging fins at the lower end of the front or back side door body engage with the lower frame groove rail to close the lower part of the shutter main body, and when the main body is pulled horizontally, the groove rail length becomes longer. As a result, the shutter main body protrudes two door body connection frames for each of the front and rear surfaces while keeping the four door body connection frames suspended above the upper frame rails. While folding, it opens.

[Embodiment] The embodiment will be described below with reference to the drawings. In the drawings, reference numeral 1 is a top-hanging horizontal pulling shutter provided with a lower closing device 2 of the present invention. Four
Further, the shutter main body 7 is provided in the left and right vertical frames 5 and 6 so that it can be folded and opened.

In the shutter body 7 of this example, eight door bodies 8 ..., 9 ... are arranged on both sides of the front and back sides in a double arrangement (see FIG. 1 and FIG. 2), and each door body end is The four door body connecting frames 10 common to the front and rear surfaces and the two door body connecting frames 11 for each of the front and rear surfaces are alternately rotatably connected to each other so that the front and rear surfaces can be freely contacted and separated (see FIG. 3).

The front side door body 8 ... In this example is a vertical lattice door body in which the same quality square pipe shape material 13 is fixed inside a four-sided frame 12 made of an aluminum shape material. Further, reference numeral 14 in the figure is a middle crosspiece. On the other hand, the rear side door body 9 ... In the present example holds glass panels 15 and 15 in a similar four-sided frame 12.

Further, a joint piece 16 of a four-door body connecting frame 10 (common to the front and rear door bodies) having four joint pieces on the right or left end vertical edge of each door body 8 ..., 9 ...
, Which is rotatably fitted to and connected to the door, while the other vertical edge has two joint pieces 17, 17, which is a two-door body connection frame 11 (separate front door body)
Similarly, the door bodies are alternately rotatably fitted, and the door bodies are alternately connected to both connection frames.

The door body connecting frame 11 of this example 2 is formed separately in the left and right portions 18 and 19, and the shutter main body 7 is formed with four door bodies connected to the four door body connecting frame 10 in an X shape as a unit. It can be hung on the frame rail 20, and after this hanging, the left and right parts 18, 19 of the two door body connection frames 11 ... Are screwed (21 in the figure) to form a series of shutter bodies 7 of full length.

In this example, the shutter body 7 in this example, which is 16 double doors 8 ..., 9 ...
As shown in the figure, a door roller provided at the upper end of each four-door body connection frame 10 ...
22 (or a sliding body) is hung and run on the upper frame rail 20 and, as shown in FIG. 3, the two door body connection frames 11 ... It is possible to fold it like a bellows.

On the other hand, at the lower end of the rear side door body 9 ... In this example, a hanging fin 23 ... Is integrally projected over the lower frame lower edge full length (or slightly longer than this), and is engaged in the groove rail 24 of the lower frame. While closing the lower part of the shutter body 7 together, the shutter body 7
With the folding and opening of (1), it can be detached from the detaching port 25 in which the rear side surface of the lower frame groove rail longitudinal end portion of the door pocket portion 41 is removed.

Further, in the figure, 26 is a door pocket plate, 27 is a floor surface, 28 ... is a long anti-vibration piece provided at the lower end of the 4-door connecting frame, and is always engaged in the lower frame groove rail including the door pocket. On the other hand, a short anti-vibration piece 29 in the figure is provided at the lower end of the two-door body connection frame 11 ... Engages in the lower frame groove rail 24 and is detachable from the detaching port 25 in the door pocket. .

Here, the relationship between the long / short swing-off pieces 28, 29 ... And the door hanging fins 23, etc. of the present example will be described with reference to FIG. 6 (see also FIG. 4 and FIG. 5). The swing-off pieces 28 and 29 are both made of synthetic resin, and have a horizontal base portion 30 and a hanging substrate 31.
And is integrally molded into a T-shape or an inverted L-shape,
Of these, the long anti-vibration piece 28 fixes the horizontal base 30 to the four joint pieces 16 of the four-door body connection frame 10 with screws (32 in the figure) and also vibrates to the left and right of the back side of the lower end of the hanging board. Large protrusions 33, 33 for contraritory, and conversely, small protrusions 34, 34 for vibration prevention are integrally provided on the left and right sides of the front side. Reference numeral 35 in the figure denotes a reinforcing thick portion of the hanging board.

On the other hand, the short vibration prevention piece 29 has its horizontal base portion 30 screwed only to the two joint pieces 17 and 17 of the rear two door body connecting frame (3 in the figure).
6) However, it is not fixed to the front two-door connection frame. In addition, the large and small vibration stop projections integrally formed on the lower end of the large vibration prevention pieces 37, 37 are on the front side of the hanging substrate 31, and the small projections 38, 38 are on the rear side, contrary to the long vibration prevention piece. Have. In the figure, 39 and 39 are driver insertion grooves formed on the short vibration-preventing piece for screwing.

When the shutter body 7 of this example is closed, the hanging fins 23 at the lower end of the rear door body have their longitudinal ends at the hanging bases 31 and 31 of the long and short anti-vibration pieces 28 and 29, as shown in FIG. (That is, from the rear side with respect to the long anti-vibration piece 28 at the lower end of the four-door body connection frame, and from the short-side anti-vibration piece 29 at the lower end of the two-door body connection frame on the rear side). However, as a result, the hanging fins 23, which are shorter than the door body, are continuous over the entire length of the shutter body 7 in the longitudinal direction via these swinging pieces 28 and 29 at the lower end of the connecting frame. Then, the lower part of the body is closed.

As shown in FIG. 4, the ends of the hanging fins 23 of this example have a slight gap 40, 40 with respect to the hanging substrates 31, 31 of the long and short vibration-preventing pieces.
Although they are face-to-face polymerized with each other, this may of course be completely abutted.

The engagement of the fins, pieces, etc., in the lower frame groove rail of this example is such that the door hanging fins 23 have a relatively large clearance as shown in FIG. Although the runout fin 23 is prevented from hitting the rail, the drooping fin 23 may be brought closer to the inner side surface of the groove rail, if necessary.

Although not shown in other figures, the door body can be connected to the 4 or 2 door body connection frame by partially fitting a hinge or the like in addition to fitting the vertical edges over the entire length as in the illustrated example. Further, the hanging fins may be provided on either the front side or the back side door body, and the door pocket portion is arranged accordingly.

Of course, the constitution of the surface portion of the front and rear door body can be selected in various ways, for example, both sides can hold glass panels, or one side can be a movable louver and the other side can be a glass panel to adjust the amount of light.

Although the embodiments are configured as described above, the present invention does not violate the above-mentioned gist, and the door body, the four door body connecting frame, the two door body connecting frame,
The specific shape, structure, material, size, number of members, arrangement and relationship of shutter body, door roller or sliding body, upper frame rail, hanging fin, lower frame, groove rail of lower frame, door pocket, etc. Needless to say, the present invention is not limited to the above embodiment.

[Advantages of the Invention] Since the lower frame closing device of the horizontal pulling shutter of the present invention is configured as described above, various panels are provided on the front and rear doors.
It can be equipped with a combination of lattices, for example, it selectively has the characteristics of a double door such as compatibility of daylighting and crime prevention, and also has a hanging fin protruding from the lower end of the door body in the groove rail of the lower frame. Since the lower part of the door body is closed together, the prospective width of the lower frame can be limited to a relatively small width even with such a double door, and the cost can be reduced and the lower part of the door body can be sufficiently closed. it can.

Further, the hanging fin of the closing device of the present invention is sufficient if it is provided on either the front or rear side door body so as to be engaged with the lower frame groove rail, so that the door pocket has a double door body despite having the double door body. The part may be provided on one of the front side and the back side, there are few restrictions on the floor space, and since the lower frame groove rail in the door pocket part can be removed on only one side, it is advantageous in terms of dust prevention, etc. Can be
