Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a vertically-pulsing building shutter, and more particularly, to a vertically-pulling panel shutter in which panels are sequentially stacked or simultaneously folded and opened in a uniform manner.

(Prior Art) Conventionally, this type of panel shutter has used fixing frames such as U-shaped grooves in cross section on the left and right vertical frames to hold the ends of the shutter body in an enveloping manner. As seen in No. 33990, each connected panel of the shutter body is pulled up and opened in the extended state, and the guiding direction is changed from vertical to attic depth direction using the ML and T52 guide members in the upper door pocket. However, it was supposed to be folded in a vertical reciprocating manner only from the upper panel body.

The reason why the conventional upper-folding panel shutter changed the guiding direction in the upper door pocket is because if this was not done, the weight of each panel body would cause the descending blades to remain in the folded state, causing the reverse. This is because the extension from the lower panel body could be hindered, leaving a problem in the extension introduction to the fixed left and right vertical frames.

(Problem WU to be solved by the invention) For this reason, according to the conventional panel shutter, all the panel bodies are first pulled upwards while being held in a fixed vertical frame and then folded sequentially from the upper side. It was very heavy, and it was inconvenient because you had to push the whole thing open just to get a small opening.

On the other hand, when lowering and closing this, it is necessary to extend the lower door body in order, so the above-mentioned guide member is provided in the ceiling and the storage guide direction is changed from vertical to depth direction in advance. This required countermeasures such as keeping the shutter in place, making the overall shape of the shutter bulky and making it complicated to fit into the building.

Furthermore, as a result of this direction change, the panel body of the vertical shutter is folded in a vertical reciprocating manner, resulting in a panel body that is reversed front and back, requiring a 180 degree rotation at the connecting part, which makes it difficult to use extruded materials, etc. It is difficult to use an integral surface member, the connecting portion becomes complicated and requires a lot of man-hours, and the design may lack simplicity.

The present invention was made in view of the problems of conventional vertical panel shutters, and the present invention has been made to enable easy opening and closing of the shutter without limiting the folding position upward, to make the overall shape more compact, or to enable rotational connection of the panels. It is an object of the present invention to provide a vertical panel shutter that can simplify the structure.

(Means for Solving the Problems) The present invention has been completed in accordance with the above-mentioned object, and the shutter body is formed so that it can be folded into a sequentially stacked shape or a simultaneous uniform shape, and its left and right vertical frames are formed into openings. The shutter can be protruded and retracted at the left and right end positions in conjunction with the opening and closing operations of the shutter body, and the gist of the present invention is a vertically drawn panel shutter as set forth in the claims.

The top-hung shutter body has a plurality of panels that are rotatably connected and can be pulled vertically up and down, and can be folded and expanded to open and close openings in buildings. And especially,
The opening/closing mode of the shutter body of the present invention eliminates the conventional method of folding upwards from the upper end panel, and instead stacks the panels one by one or simultaneously uniformly from the lower fixed position '11 (for example, the lower frame of the shutter or the ground level, etc.). It is foldable.

That is, as an example of a sequentially stacked shutter main body configuration, for example, a large number of panels are arranged vertically in parallel, their upper and lower edges are rotatably connected, and every other one of the panels is provided with a vertical frame guide door roller at the rotatable joint. At the same time, by lifting the lower end panel or the lower end door stop member of the shutter main body, the above-mentioned pivoting joint is regulated on the vertical frame rail line, and the other pivoting joint is horizontal. They can be made to protrude in this direction and can be folded in a stacked manner sequentially from the lower panel.

On the other hand, in order to form a shutter body that can be folded simultaneously and uniformly, for example, it is recommended to provide a guide door wheel for each rotatably connected panel at every other rotatable joint as in the above example. Instead, they should be placed near the center of each panel's vertical width. When it is lifted, the panel will rotate while being regulated on the vertical frame rail line at the center of its vertical width, and each rotation connection part will be rotated. This rotational movement is transmitted to the connected panels, allowing them to be folded uniformly and simultaneously. Incidentally, even if such a central door system is not used, the same operation can be obtained by adding a pantograph-like link mechanism to the shutter body.

Next, regarding the folding mechanism of the shutter body, this can be selected from a bellows shape, a superimposed shape, and an equiaxial shape. That is, in this example, for example, a connecting horizontal frame having an integral rotation connecting part that fits male and female is arranged between each of the door bodies arranged vertically in large numbers,
A bellows-shaped shutter main body can be constructed by connecting the pitcher force direction link of the upper and lower door bodies adjacent to each other via the connecting horizontal frame. In addition, for example, by converting the mechanism of Japanese Patent Application No. 108239/1982 proposed by Undeveloped IJJ to horizontal and vertical conversion, and opening each door body in a horizontal cantilever shape using a connecting frame and a link, a superimposed shutter body can be created. may be configured. Alternatively, two of these bellows-shaped or overlapping shutter bodies may be arranged in a 1ν arrangement in the front and back so that the front and rear can be opened and closed freely. Any folding mechanism can be employed.

Of course, each panel constituting the shutter body can be selected and combined in various ways, such as a single plate or a glass panel fitted and held in a four-frame frame. In addition, the materials of these panels, the vertical frames described later, and the horizontal frames connecting panels that are arranged as necessary can be made of aluminum alloy extrusions, metals such as stainless steel, or synthetic resins depending on strength conditions. A variety of materials can be selected, such as wood-based materials.

In addition, the above-mentioned means for suspending the shutter body may be, for example, a wire rope that can be wound up and unwound around the upper drum and connected to the lower end door body or the lower end door stop member connected thereto; It is also possible to use a single hanging chain or a reciprocating ring chain connected to the upper or lower sprocket. Note that when the shutter body is formed to be foldable simultaneously and uniformly, the folding rotation is transmitted to each panel, so the lifting portion does not necessarily have to be limited to the lower end of the shutter body.

On the other hand, the vertical frames arranged on the left and right sides of the shutter main body fix the shutter main body upright at the left and right end positions of the building opening so that it can be freely protruded and stored.

As an example of this left and right vertical frame that can be protruded and stored, for example, the Oritan door railing 211 (consisting of separate inner and outer rails) of the patent application dated January 14, 1986, proposed by the present inventor, is used for building openings. Various methods are used, such as being embedded and fixed in the widthwise wall of the section, or being housed in a single vertical frame on the left and right sides with U-shaped grooves, so as to protrude freely into the recessed groove formed in the wall. configuration can be used.

A protruding storage device attached to the vertical frame is linked to the opening/closing operation of the shutter body, so that the shutter body can be freely raised and lowered in the vertical frame stored state.

The protruding storage device is also mentioned in the explanation of the rail device for folding doors proposed in Hikari above, but it is possible to install a connecting rotating arm or an inclined storage device between the vertical frame and a separate frame on the outside or a fixed part such as a building wall. It can be constructed by including a guiding device (for example, a combination of an inclined block and a door roller, a combination of an inclined guide groove and a guide pin, a combination of sliding VC inclined vanes, etc.).

In addition, although such a connecting rotation arm and a tilt guide device are made to protrude or retract with the vertical movement of the vertical frame, it is also possible to make them protrude and retract without such vertical movement.
For example, an eccentric cam pivotally attached to the fixed portion may be brought into sliding contact with the back surface of the vertical frame, or a pantograph-like link mechanism may be provided between the vertical frame and the fixed portion. Note that in large automatic shutters and the like, the use of electromagnets has the advantage of simplifying the mechanical structure.

On the other hand, the interlocking means of such a protruding storage device to the shutter body should be set appropriately depending on the type and structure of the device. The vertical frame or the protruding storage device may be provided with a suppression receiving portion that can freely come into contact with the vertical frame or the protruding storage device. Examples of configurations of the suppression receiving part include, for example, blocking the longitudinal end of the guide groove of the shutter body formed in the vertical frame and fixing the receiving part (as the main body opens and closes, the upper and lower parts of the vertical frame 1), or by extending the receiving arm from the rotation axis of the connecting rotation arm and the protruding storage device.

By the way, by storing the vertical frame in conjunction with the opening/closing operation of the shutter body, the T-shutter body in the stored state can be raised and lowered freely, but it is not necessary to completely release the vertical frame from holding the ends of the shutter body. (Although it may be released), for example, parts such as a door wheel for lifting guide and sliding parts that should always be located on the vertical frame rail line without locking, such as the shutter body in the folded state, may be maintained in this retained state. In order to maintain this, for example, these parts may be provided to protrude slightly longer on the left and right sides of the shutter body.

In addition, the vertical frame holds the left and right ends of the shutter body in the protruding state, but the held parts of the shutter body are
There are various settings depending on the type of constituent panels and the presence or absence of a connecting frame interposed between panels.1 For example, the side of a veneer-like panel, the left and right vertical frames of a stile-like panel, or the left and right ends of a panel or connecting horizontal frame. Examples include a steadying member, a door wheel, a sliding member, etc. that protrudes from the part.

In addition, although it is desirable for this holding to be carried out in an enveloping manner, the vertical frame does not necessarily have to form a U-shaped groove in the front and rear corner fins. When it is folded, it may be sufficient to use one side as a fixed fin and the other side as a single fin-shaped protruding storage vertical frame. Also, regarding the retention of the above-mentioned letter of inclusion.

It is also possible to change the holding/wrapping function between the end of the shutter body and the vertical frame.

As described above, the present invention includes specific shapes of panels, shutter bodies, vertical frames, openings, protruding storage devices, etc., 4Ii structure, materials, dimensions, number of n, arrangement, and relationships thereof, unless contrary to the above-mentioned gist. It goes without saying that the folding mechanism of the shutter body, the interlocking means of the protruding storage device, etc. can be modified in various ways, and are not limited to the following embodiments.

(Function) As a result of the above, the shutter body has left and right vertical frames that can be freely protruded and stored in conjunction with the opening and closing operations of the shutter body, and while the vertical frames are stored, the panels can be sequentially stacked or simultaneously folded uniformly from the lower fixed position. It can rise or, conversely, descend freely.

(Example) Below, IJJ will explain the example with reference to the drawings.
1 in the figure is a vertical panel shutter according to the present invention,
The panel shutter 1 has a shutter body 2 and left and right vertical frames 3, 3, and is installed in a building opening 4. In the figure, 5 is the upper frame of the shutter, 6 is the lower frame, and 7 is the upper door pocket.

The shutter main body 2 of this example has a large number of panels 8 connected rotatably through connecting horizontal frames 9 so that it can be folded and opened and closed, and the opening and closing form is sequentially raised. , the opening/closing mechanism is configured in a bellows shape (see Figures 1 to 4).
(see figure).

Panel 8... is the top, bottom, left and right frames (10a, 10b, 1
0c, 10d) are assembled into frames around the four sides, and glass panels 11 are fitted and held inside the frames. The vertical width of the panel is approximately 20 cm (however, the short width panels at the top and bottom ends are 8° and 1/2 of that), which is slightly wider than the roll-up slats. Furthermore, extruded aluminum alloy members are used for both the frame and the stile.

The left and right ends of each panel 8 are provided with a door wheel 12 at the center of the vertical width, and as a result, the shutter body 2 of this example is opened and closed sequentially from the lower end fixed position. ing. In addition, the short width panel at the top and bottom ends is 8°,
8' is provided with a door roller at one end position above or below.

On the other hand, a hinge connection part 13.13 is integrally molded on the entire length of the upper and lower frames 10a, 10b of each panel 8 in this example, and this is integrated into the hinge connection part 14 of the connection horizontal frame 9 placed between each panel. ．．
14 and are rotatably connected to each other, and the resultant panel 8 can be folded and opened into a bellows shape. In the figure, reference numerals 15, . . . are steady-stop parts provided at the left and right ends of the connecting horizontal frame.

Further, the upper hanging means of the shutter main body 2 of this embodiment includes a wire rope 17, 17 that can be freely wound up and unwound around the upper drum 16 and connected to the lower end door stop member 18.

On the other hand, the left and right vertical frames 3.3 of this example consist of separate inner and outer frames 19.20, and the inner and outer frames are installed in the grooves of the outer frame 20 which is embedded in the left and right ends 21.21 of the building opening 4. 19 is erected and fixed so that it can be freely protruded and stored (see FIGS. 5 to 8).

The protruding storage device 22 of this example has the above-mentioned separate inner and outer body frames 19.
．． A stainless steel connecting rotation arm 23 is provided between the inner frame 19 and the inner frame 19 so as to protrude as the inner frame 19 moves in the longitudinal direction. In the figure, reference numeral 24 denotes a tension spring stretched between the 1M connecting rotation arm 23 and the outer frame 20, which biases the inner frame 19 in the storage direction. Further, the connecting rotation arms 23 are arranged at a plurality of positions in the vertical direction of the vertical frames 3, 3.

Further, the means for interlocking the opening and closing operations of the shutter body 2 of the protruding storage device 22 is, for example, the shutter body 2.
A pressing part 25 protrudes from the left and right ends of the lower end door stop member 18, and a feather-shaped stainless steel suppression receiving part 26 fixed to the outer frame side rotation shaft of the lowest position connecting rotation arm 23. Become.

Then, when the shutter body 2 is closed and lowered, the connecting rotation arm 23 rotates, causing the inner frame 19 to protrude, so that the left and right ends of the shutter body 2 and their steadying parts 15 are held in the inner frame groove. The engagement is maintained. On the other hand, when the shutter body 2 is opened and raised, the reverse rotation receiving part 27 fixed to the outer frame side rotation shaft of the connecting rotation arm 23 is pressed against the suppression part 25 of the shutter body, and the spring The rotation arm 23 is reversely rotated by the biasing force 24, the inner frame 19 is retracted, and the engagement and retention of the shutter body 2 is simultaneously released over the entire length in the vertical direction, except for the single door car 12.

(Effects of the Invention) The vertical panel shutter of the present invention operates as described above, and the shutter body can stably hold its ends in the closed state by storing the left and right vertical frames in a protruding manner. On the other hand, in the case of DI, the holding state can be released entirely, so there is no need to pull up all the panel bodies while holding them on the vertical bars, and the panels can be lifted up one by one from the lower fixed position. It can be folded into a uniform shape or simultaneously, and can be opened and closed easily.

In addition, by using such stacked or uniform opening/closing shapes, there is no need for any special structure or IA location for lowering and closing the shutter body. Since there is no inconvenience such as having to rotate 180 degrees, and it is sufficient to simply fold the shutter horizontally while pulling it vertically, the overall shape of the shutter can be made compact, and the connecting structure of the panels can be simplified. can.

On the other hand, since it is sufficient for the vertical frame to protrude and hold the shutter body only when it is closed, it is possible to improve airtightness by making the clearance with the shutter body small.

Further, when the shutter is closed, the left and right vertical frames are housed at the left and right ends of the opening, so that the appearance of the shutter can be made simple and a wide width of the left and right openings can be ensured.
