Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a shutter provided at an opening in a building, etc., and particularly relates to a shutter that can be brought into a vertically folded state and can be brought into the vertically folded state without being wound up on a drum. This relates to a vertically folding shutter that can be freely stored above the shield.

(Background Art) The present inventor focused on the disadvantages of installing a shutter box in a roll-up type shutter, the uniformity of the design of roll-up type pipe shutters, etc.

Invented a vertical folding shutter and applied for a patent application from 1983 to 1315.
A patent application has been filed as No. 16.

This vertical folding shutter connects a large number of horizontal bars in the vertical direction with telescopic links, and is inserted into the left and right ends of these horizontal bars, and has a lower horizontal bar (including end slats with different shapes).
It is designed to be vertically foldable by winding up a wire or chain fixed to the K, and also to be able to be stored above the shield in the vertically folded state. Even if the horizontal bars are formed, their weight is quite large, and as a result, if the wire or chain breaks due to long-term use or external force, each horizontal bar is not fixed, so there is a danger that the horizontal bars may fall. There was a need to eliminate the possibility of this happening and to make opening and closing more stable and smooth.

(Objective of the Invention) The present invention solves these problems in a vertical folding shutter, and provides a shutter that maintains its shape even when closed or opened, and is safe against breakage of wires or chains. The purpose of this paper is to propose a concrete structure for

(Structure of the Invention) The present invention provides telescoping links at two or more IC locations in the lateral direction of the transverse bars, and integrally provides auxiliary bars on these telescoping links in a bridging manner.

The present invention solves the above-mentioned objects specific to vertical folding shutters.One aspect of the present invention is to connect a large number of horizontal bars in the vertical direction by telescopic links, which are inserted through the left and right ends of these horizontal bars, and fixed to the lower horizontal bars. In a vertically folding shutter that can be vertically folded into a stacked shape by winding wires or chains and can be stored above the shield in the vertically folded state, two or more telescopic links are installed in the left and right direction between each horizontal frame. , each link has one end pivotally fixed to each horizontal beam, and the other end pivoted so as to be movable left and right, and at the middle part of the link, a link crosses between these middle parts in a construction form and is integral with this. The gist of this invention is a vertical folding shutter characterized in that an auxiliary crosspiece is interposed between horizontal crosspieces that are pivotally fixed to the horizontal crosspieces.

An embodiment will be described below with reference to the drawings. In the drawing, reference numeral 1 denotes a vertical folding shutter according to the present invention, and this shutter 1 has a large number of horizontal bars 2 made of aluminum alloy arranged in parallel in the vertical direction. Each of these horizontal bars 2... is vertically connected between adjacent horizontal bars 2 by telescopic links 3, and
Fixed blocks 2 of end slats 21 are inserted into the through holes 23 of the resin blocks 22 fixed to the left and right ends of these horizontal bars 2... and are provided as lower end horizontal bars.
Left and right wires 4.4 are fixed to the guide rail 5.5, inside the guide rail 5.5 -C', and are passed through a pulley 8 to the winding shaft 7 by the motor p-6. By winding it up, the horizontal bars 2 can be vertically folded into a stack in order from the bottom.

This folding shutter 1 does not have a conventional winding drum, and in this folded state, the shutter 1
It is configured to be housed between guide rails 5, which extend integrally or separately to the attic space above fI9.

The telescoping links 3 in the folding shutter 1 having such a basic configuration are, in the illustrated example, diagonal beam-shaped links 3.3 made of aluminum alloy provided at the front and rear, respectively, without fixing their intersection points. 2 are provided at four locations each in the front and rear in the longitudinal direction of the horizontal beam 2, that is, in the left and right direction.

That is, each telescopic link 3.3 has one end, in the illustrated case, its lower end, connected to an L that is erected and fixed on the upper surface of the horizontal bar 2...
The end slat 21 is pivotally supported by a block 32 and reinforced with a block 32, and the end slat 21 is pivotally fixed to the rising piece 26, while the other end (in the illustrated case, the upper end) is
A car 33 sliding on the front and rear groove rails 25.25 of the horizontal beam 2.
33, and is pivoted so that it can move left and right.

On the other hand, reference numeral 10 denotes an auxiliary bar, and the auxiliary bar 10, like the horizontal bar 2, is made of aluminum alloy and is formed into a hollow pipe shape. The auxiliary crosspiece 1o intersects between the intermediate portions of the front front side links 3 in each of the links 3, and is pivotally fixed integrally therewith. That is, a spacer 11 is provided between the link 3 and the auxiliary crosspiece 10, and a fixing metal fitting 12 is provided at the center of the link 3.
It is integrally pivotally fixed.

In this way, the auxiliary beams 10 are fixed to the links 3 at their intermediate portions, and are interposed between each of the horizontal beams 2.

In addition, in the figure, 27 indicates a cushion material, and 51 indicates a sound deadening backing for the guide rails 5, 5, respectively.

By the way, the front and rear telescopic links 3.3 are integrally connected at their intersections.
The ζ pivot can be fixed to form a single X-shaped link. But this one.

Unlike what is shown in the diagram, one end that is pivoted and fixed to the horizontal bar 3 is
The other end, which is the upper and lower ends of the letter-shaped link and to which the horizontal beam 3 is pivotally attached so as to be movable left and right, is the opposite side end. In this way, the auxiliary crosspiece 10 can be intersected in an erected manner at the intersection of the X-shaped links and pivotally fixed thereto.

In this case, it is necessary to change the shape of the horizontal crosspiece 2 on the pivotally fixed side as appropriate.

In addition, even when using the above-mentioned front and back telescopic links 3, the means for pivoting and fixing the pivots are not limited to those shown in the figures, and the auxiliary beams 10 are also arranged alternately in the front and rear for each link installation location, or in the rear. Needless to say, it can be pivotally fixed to the side link.

On the other hand, in the vertical folding shutter 1 configured as described above, the wire 4.4 is wound up by the forward rotation of the motor 6, and the wire 4.4 is unwound by the reverse rotation IC to open and close the shutter 1. At this time, if the lower end horizontal bar 2 rises, the horizontal bars 2... are stacked one after another from below, and if this descends, the shutter 1 is sequentially closed from above. That is, in the open state, ring 3
A stopper (not shown) that restricts the left and right movement of the link restricts the opening and closing of the link and regulates the spacing between the horizontal bars 2...
When the lower end lower crosspiece 2 rises, the relinks 3... are contracted and housed in the horizontal crosspiece 2, and this is successively propagated to the upper horizontal crosspiece 2, and the shutter 1 is opened. On the other hand, when the lower end horizontal bar 2 descends, the link expands until it is regulated at the stopper position, and in this way, the link propagates to the lower horizontal bar 2, and the shutter 1 is closed.

The present embodiment is as described above; however, in carrying out the present invention, the specific shape, material, and structure may be changed in various ways as long as it does not go against the gist of the invention, and the present invention is not limited to the above embodiment. isn't it.

Effects of the Invention The present invention provides a vertical shutter that is vertically foldable and can be stored above the shield in the vertically folded state, so that one of the wires or chains inserted through each horizontal beam breaks and breaks due to deterioration over many years or external force. When two or more links intersect in the middle part of the bridge and are fixed integrally with each other, the auxiliary beam installed between each horizontal beam (C) is broken, and the link on the cut side is in the shutter closed state. Even if an attempt is made to open the shutter, this is restricted, and even if a portion of the horizontal beam falls in an inclined manner, one side of the shutter will not fall down significantly.

In addition, the structure of the auxiliary beam improves the shape retention of the shutter, making opening and closing smooth, suppressing back and forth vibrations, and further improving the strength against external forces when closing the shutter.

Furthermore, since the auxiliary crosspieces as well as the telescopic links serve as partitions for the shutter, the number of horizontal crosspieces can be reduced, which is effective in lowering costs.

As described above, the present invention is an excellent invention that solves the problems peculiar to vertical folding shutters.
