[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a structure for mounting slats in blind shutters installed in windows of buildings, etc.

[Problems to be solved by the prior art and the invention]

Generally, in this type of blind shutter, as shown in FIG. A chain 10 is suspended, and the chain 10 is connected to the lower end of a link 11 which is telescopically connected in a pantograph shape, and the slat 1 attached to the link 11 is raised and lowered, while the angle transmission lever 1
Some devices are constructed so that by rotating the slat 1 by moving the opening 3, the opening can be opened and closed and light can be brought in or blocked out.

By the way, in this case, conventionally, link 11
In order to attach the slat 1 to the slat 1, the slat support plates 12 are fixed in pairs to the pivots passing through the respective cross supports of the links 11, and the slat 1 is held between the slat support plates 12 and the clamping member 12a and fixed with screws. It was installed by doing this. However, if you do this, you can connect slat 1 to link 11 for repairs etc.
When removing the slat 1 from the slat support plate 12 and the clamping member 12a, it is necessary to loosen the screws one by one and pull out the slat 1 from the slat support plate 12 and the clamping member 12a.Furthermore, when reattaching the slat 1, it is necessary to tighten the screws again, which is a troublesome and troublesome process. There was a problem that it was complicated and extremely poor in workability.

[Means to solve the problem]

In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a mounting structure for the slats in a blind shutter that can eliminate these drawbacks, and is capable of moving up and down and rotating around an axis. In a blind shutter constructed by attaching slats to a plurality of pivots so as to be able to open and close an opening and to let in and block out light, a shaft seat is integrally attached so as to protrude from the back side of both ends of each of the slats. and a support fitting integrally connected to the pivot, the shaft seat having a sharp locking edge at the opposite end, and the support fitting having a locking plate having toughness. Further, this locking plate has a pinching side bent at both edges so that the opposite edges are in a small opening state with a narrow width and the locking edge of the shaft seat can be tightly clamped. , and a push-in operation part that bulges out in the opposite direction to the clamping sides is formed in the center, and when the push-in operation part is pushed in, the direction of the expansion is reversed, thereby expanding the opening width between the clamping sides. When the locking plate is opened and transformed into a large opening state in which the shaft seat can be loosely fitted, the locking plate in the large opening state with the shaft seat loosely fitted is pushed in the direction opposite to the gripping side by the pushing operation part. The slat is characterized by a structure in which the slat can be detachably attached to the pivot side by returning to its original bulging position.

With this configuration, the present invention allows the slat to be easily attached to and detached from the support fitting.

〔Example〕

Next, one embodiment of the present invention will be described based on the drawings. In the drawing, slats 1 constitute the curtain of a blind shutter A, and these slats 1 move up and down and rotate to open and close the blind shutter A and let in light.
Light-shielding operation is now in place.

That is, the blind shutter A is connected to the switch 16.
A drive shaft 9 is interlocked with the drive shaft 9, a chain 10 is suspended from sprockets provided at both left and right ends of the drive shaft 9 and the lower end of the guide rail 8, and a chain 10 is fixed at the upper end and moves vertically within the guide rail 8. Pantograph-shaped link 11 that expands and contracts, said link 1
1, and a slat receiving plate 14 that is attached to the lower end of the link 11 and interlocked with the chain 10, and a pivot shaft 1 of the link 11.
The slat 1 is integrally provided on one side of the slat 1a.
It is composed of a support fitting 7, which will be described later, that supports the pivot shaft 11a, an angle transmission lever 13 that is integrally provided on the other side of the pivot shaft 11a, an auxiliary rail 15 that engages with the angle transmission lever 13 so as to be movable in the vertical direction, and the like. In this configuration, by driving the switch 16, the slat receiving plate 14 moves up and down within the guide rail 8 via the drive shaft 9 and the chain 10, thereby the link 11 expands and contracts, and is attached to the support fitting 7. The supported slat 1 is configured to move up and down while remaining horizontal. Further, at approximately the lowest end position of the curtain, the lower end of the auxiliary rail 15 is engaged with and guided by the slat receiving plate 14, so that the auxiliary rail 15 moves back and forth and rotates the angle transmission lever 13, thereby causing the slat support plate 14 to rotate. 1 rotates to take a vertical position, and the blind shutter A enters the light-shielding state, etc., as usual.

The slat 1 is formed with a wide protruding flat surface 1a that protrudes from the front side, and a shaft seat 2 is fixed to the rear side surface 1b of the protruding flat surface 1a at both left and right ends with rivets or the like. This shaft seat 2 has a plate shape, and sharp locking edges 2a are formed at its upper and lower ends, and the surface 2b in contact with the slat back surface 1b is flat, but the back surface 2c The center part is concave.

On the other hand, 3 is a support plate that supports the slat 1, and a positioning piece 3b bent in an angular shape is formed from a plate-shaped base plate 3a. 11a
A short cylindrical support shaft 4 is provided which is integrally attached to the shaft. Further, reference numeral 5 denotes a plate-like locking plate made of a thin steel plate with toughness, and the upper and lower edges of the locking plate 5 are formed with holding sides 5a that are bent into a substantially hook shape when viewed from the side. Further, in the center of the plate surface of the locking plate 5, there is provided a push-in operation part 5b that bulges upward into a bowl shape. Reference numerals 3c and 5c are rivet holes, which are bored approximately at the center of the support board 3a and the push-in operation part 5b, respectively.The support plate 3 and the locking plate 5 are
With the support substrate 3a in contact with the upper side of the push-in operation portion 5b, rivets 6 are driven into the holes 3c and 5c to integrate the support substrate 3a and assemble it into the above-mentioned support fitting 7. And the push operation part 5 of the locking plate 5
When b is pushed in with a finger through the support substrate 3a, the bulging direction is reversed as shown by the solid line in FIG.
The opening between 5a expands from a small opening state (opening width k ₁ ) to a large opening state (opening width k ₂ , k ₁ <k ₂ ).
Conversely, by pushing both the clamping sides 5a, 5a together, the inverted pushing operation part 5b returns to its original position, and the opening between the clamping sides 5a, 5a narrows from its large open state. It is designed to transform into a small opening state.

Further, the slat 1, the shaft seat 2, and the support plate 3 are made of aluminum extrusion molded material, and the clamping side 5a of the locking plate 5,
The pushing operation portion 5b and the like are formed by, for example, press processing.

In the embodiment of the present invention constructed as described above, the support shaft 4 of the support metal fitting 7 is integrally attached to the pivot 11a of the link 11. In order to attach the slat 1 to the support metal fitting 7, first, At the left-right positioning position where the corner of the positioning piece 3b is in contact with the outer surface of the shaft seat 2 on the slat side, the clamping edge 5a of the support fitting 7 is set at the position of the locking edge 2a of the shaft seat 2, and this In this state, push in the push-in operation part 5b to reverse the expansion direction, and as described above, make the opening between both the clamping sides 5a, 5a into a large opening state where the opening width is k ₂ , and in this state, both clamping sides 5a,
Fit the shaft seat 2 between the spaces 5a, and then sandwich the holding sides 5a, 5a from both sides to form the push-in operation part 5.
If b is returned to its original position, both clamping sides 5a, 5a
The slat 1 is in a state of a narrow opening width k ₁ and is tightly locked to the locking edge 2a, thereby making it possible to attach the slat 1 to the support fitting 7. Incidentally, in this case, if the above-mentioned installation work is carried out in a half-pressed state without fully pressing the push-in operation part 5b, the expanded locking plate 5 can be returned to its original state without pinching the clamping sides 5a from both sides. Since it is possible to return automatically, work efficiency is further improved, and it is of course possible to do it this way.

On the other hand, when it is desired to remove the slat 1 from the link 11 for repair or cleaning, push in the push-in operation part 5b of the support fitting 7 to open both the clamping sides 5a, 5a again, and connect the locking edge 2a. All you have to do is release the lock and remove it.

In this way, in the present invention, the push-in operation section 5b
Both clamping sides 5 expanded by pushing in
The slat 1 can be easily attached to and detached from the support fitting 7 by fitting the shaft seat 2 into the opening between a and 5a and returning both the clamping sides 5a and 5a to their original narrow opening state. Become, therefore,
There is no need for the troublesome work of loosening and tightening screws one by one as in the past, and the work of attaching and detaching the slat 1 is significantly simplified, resulting in a significant improvement in workability.

Moreover, in this case, the positioning piece 3b is attached to the shaft seat 2.
Since positioning in the left and right direction is achieved by applying it to the outside surface of the Never.

[Function and effect]

In summary, since the present invention is constructed as described above, the shaft seat on the slat side is fitted into the opening between both clamping sides expanded by pushing in the pushing operation part on the support metal side, and then the shaft seat on the slat side is fitted again. The slat can be attached and detached from the support fitting very easily by returning both the holding sides to their original narrow opening state. Therefore, when removing the slats for repairs or cleaning, there is no longer any need for the troublesome work of loosening and tightening screws as in the past, greatly simplifying the work of attaching and removing the slats and improving work efficiency. A significant improvement can be achieved.
