Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a structure for attaching and detaching a slat in an electric blind shutter that is attached to a window of a house or the like.

[Problems to be solved by the prior art and the invention] In general, this type of electric blind shutter has the following problems:
The shutter slats are moved up and down and rotated using the driving force of an electric motor powered by a household AC power source to open and close the window. However, from the viewpoint of crime prevention, it is necessary to make this device so that the fully closed shutter curtain cannot be opened or closed even if it is lifted by hand. On the other hand, if electricity is cut off due to a disaster such as a fire or earthquake when the state is fully closed, the electric opening operation will no longer be performed.
This poses a problem in that it is difficult to escape quickly through the window.

Conventionally, the above problem has been addressed by providing a separate special combination mechanism that can be opened and closed manually and electrically, but this has a complicated structure, is large, and is prone to failures. However, it also had the disadvantage of increasing costs, which became a problem.

[Means for solving the problem] In view of the above-mentioned circumstances, the present invention has been devised for the purpose of providing a structure for attaching and detaching the slat in an electric blind shutter that can eliminate these drawbacks. , a plurality of left and right operating bodies, each of which is attached to both left and right ends of a plurality of slats constituting the shutter curtain, are moved up and down in conjunction with the drive of an electric motor to move up and down between a fully open state and a fully closed state. both,
Furthermore, when the fully closed state is reached, the actuating body is swung around its axis, and the adjacent slats are transformed into a ventilation position in which they are opened in a horizontal position and a closed position in which they are closed in a vertical position. In the electric blind shutter configured as above, one of the left and right actuating bodies is formed with a slide groove in which at least the notch at the end of the slat is slidably fitted in a detachable manner from the left and right directions. The other operating body is formed of a support that rotates together with the swing axis of the operating body, and a slat clip that is detachably fixed to the support,
The support body includes a clamping surface that clamps the slat surface, and an engagement part formed in a notch at the end of the slat, which are removably engaged face-to-face while being prevented from coming out in the left and right direction. An engaging protrusion with a recess, a sliding groove that guides in the left-right direction, and a fitting protrusion are formed, and the slat clip has a clamping surface that clamps the back surface of the slat, and a sliding groove that extends in the left-right direction. A fitting protrusion that slides and fits, a fitting hole that fits and locks the fitting protrusion, a locking piece that elastically locks the fitted fitting protrusion to prevent it from coming out, and the elastic The device is characterized in that a handle is provided to release the locking lock.

With this configuration, the present invention enables emergency evacuation in the event of a disaster to be performed quickly and reliably.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes a shutter curtain of a blind shutter attached to a window, and the shutter curtain 1 is composed of a plurality of slats 2 formed by extrusion molding of aluminum or the like. The blind shutter is opened and closed by vertical movement and rotation of the blind shutter.

In this configuration, when the electric motor 4 is driven forward or backward by operating an operation switch (not shown), the guide body 10 moves up and down within the guide rail 6 via the drive shaft 5 and chain 8. The link 9 expands and contracts, and the actuating bodies 11 and 12
The slat 2, whose left and right ends are supported, moves up and down, and when the shutter curtain 1 is in the substantially closed position, the fitting protrusion 13a at the lower end of the tail trail 13 fits into the guide path 10a of the guide body 10. This causes the tail trail 13 to move back and forth, causing the operating bodies 11 and 12 to rotate, thereby causing the slat 2 to rotate, but these structures are all the same as before.

Next, the relationship between the operating bodies 11, 12 and the slat clip 15 will be explained in detail. Regarding the actuating bodies 11 and 12, as shown in FIG. 4, the present invention is implemented in the left actuating body 11, and the conventional one is adopted for the right actuating body 12. , this conventional actuating body 12

The portion 12a is loosely fitted into the narrow frontage side guide groove 6a of the guide rail 6 so as to prevent it from coming off in the left and right direction.

On the other hand, the left operating body 11 in which the present invention is implemented
is the tail lever 1 inside the guide rail 6.
3b is press-fitted and fixed at the tip, and a link 9 is attached to the middle part.
The support body 14 is integrally fixed to the side of the pivot shaft 13c through which the pivot portion of the slat clip 15 is detachably fixed.

This support body 14 protrudes toward the right operating body 12 side, and has a substantially rectangular clamping plate portion 14a which becomes a substantially horizontal plate surface when the link 9 is fully opened and contracted to its maximum as shown in FIG. 3A; An engaging protrusion 14c protrudes downward from a clamping surface 14b, which is the lower surface of the clamping plate part 14a, and on which the surface of the slat 2 is clamped.
are formed integrally with each other, and a notch 2b is formed at the left end of the slat 2 to fit into the engaging protrusion 14c. Further, on both the front and rear sides of the engagement protrusion 14c, there are slide grooves 14d into which the engagement protrusions 15b of the slat clip 15, which will be described later, are vertically stacked and slidably fit in the left-right direction, and a notch on the left side of the slat 2. Engagement part 2 provided on 2b
An engagement recess 14e is formed with which the slat 2 is prevented from coming off from the left and right directions when the slat 2 is engaged, and an engagement recess 14e is formed on the lower surface of the engagement protrusion 14c. A mating protrusion 14f is formed. In addition, 14g is a shaft press-fitting part into which the pivot shaft 13c is press-fitted, and the shaft press-in input part 14gh is formed to protrude from the holding plate part 14a.
For the frontage side guide groove 6a, which has a narrow width, the shaft press-fitted part 14g is inserted into the frontage side guide groove 6a so that the link 9 is inside the guide rail 6 and the wide support body 14 is outside the guide rail 6. It fits loosely.

On the other hand, the slat clip 15 is shown in FIG.
As shown in FIG. 2, the slat clip 15 is formed by a holding plate portion 15a which is approximately square in shape when viewed from above.
A handle piece 15d projecting in a substantially T-shape is integrally formed on the outer end (right end in FIG. 6A) of the handle 5a. The upper surface of these holding plate portions 15a is connected to the slat 2.
It is a clamping surface 15c that clamps the back side of the
The holding plate portion 15a has a concave groove portion 15f cut out in the left-right direction on the side of the holding surface 15c, and a groove portion 15f that slides into the support slide groove 14d from the left and right is formed on the opposing groove peripheral edge. A mating protrusion 15b is formed, and a concave groove portion 15 is formed.
The bottom surface of the groove f has a substantially U-shape, and is surrounded on three sides by a fitting hole 15g into which the fitting protrusion 14f of the support body 14 fits in the deep part thereof. A locking piece 15e that can be elastically deformed so that the fitting protrusion 14f can pass over it, and that the fitting protrusion 14f that has passed is engaged with the locking piece 15e, and a covering piece 15h that faces and covers the fitted fitting protrusion 14f. are formed respectively.

The slat 2 is assembled into the operating bodies 11 and 12, for example, in the following manner. That is, as shown in FIG. 4, the right end of the slat 2 is pushed into the right side operating body 12 so that the slat notch 2b is slidably fitted into the slide notch groove 12c. Next, the surface of the left end of the slat 2 is applied to the clamping surface 14b of the support body 14 from a direction perpendicular to the surface so that the engagement portion 2a engages with the engagement recess 14e of the support body 14, and in this state, , while sliding the slat clip 15 with the clamping surface 15c onto the back surface of the slat 2, the fitting protrusion 14f is inserted into the fitting hole 15.
The left end of the slat 2 is attached to the actuating body 11 by fixing it in a position where it fits into the inner part of the slat 2. On the other hand, in order to remove the slat 2, you can perform the opposite operation. Specifically, if you forcibly push the handle piece 15d toward the inside of the frontage,
The fitting projection 14f comes into contact with a tapered surface 15i formed on the locking piece 15e, and the locking piece 15e is elastically deformed downward in FIG. 14f, thereby releasing the locking of the fitting protrusion 14f from the locking piece 15e and removing the slat clip 15 from the support 14, thereby removing the exposed left end of the slat 2 from the support 14. Then, the right end can be removed from the right operating body 12 by pulling the slat 2.

In the embodiment of the present invention constructed as described above, the actuating body 11 of the slat 2,
12, first the right end of the slat 2 is slid into the right operating body 12, and then the surface of the left end of the slat 2 is fitted onto the support holding surface 14b of the left operating body 11 in the left-right direction. is secured in the state in which it is secured, and in this state, insert the slat clip 1.
5 is assembled by slidingly fitting it into the support body 14 so that the holding surface 15c is applied to the back surface of the slat 2. On the other hand, when removing the slat 2, the gripping piece When 15d is forcibly pushed towards the inside of the frontage, the locking piece 15e
is elastically deformed to release the locking between the locking piece 15e and the engagement protrusion 14f, whereby the slat clip 15 can be removed from the support 14, and the left end of the slat 2 exposed in this way is attached to the support 14. It is sufficient to remove the right end from the right side operating body 12 by pulling the slat 2. As a result, when it is impossible to open or close the shutter curtain 1 due to a power outage, in case of emergency escape from the window closed by the shutter curtain 1,
If you put your finger on the handle piece 15d of the slat clip 15 and force it inward, the slat 2
can be easily removed, and by repeating this operation and removing several slats 2, an opening for escape will be created.

As described above, in the present invention, one end of the slat 2 is held between the support body 14 fixed to the link 9 side and the slat clip 15 that is slidably fitted to the support body 14. The extremely simple configuration of just the handle piece 15d makes it possible to escape in the event of an emergency when the opening/closing operation cannot be performed due to a power outage, etc.
This eliminates the need for complicated special mechanisms as in the past, simplifying the structure, and thus making it possible to significantly reduce costs. Moreover, the handle piece 15d
By providing this, the contact surfaces of the slat clip 15 and the slat 2 are extended toward the opposing operating body 12 side, so that reinforcement against loads from the outdoor side can be achieved at the same time.

It should be noted that the present invention is of course not limited to the above-mentioned embodiments, and for example, the handle piece 15d
may be configured to be detachable from the slat clip 15 as shown in FIG. 8, or may have a shape as shown in FIG. 8A.

[Operations and Effects] In summary, the present invention is constructed as described above, and the actuating body to which one end of the slat is attached is formed of a support that holds the front and back surfaces of the slat, and a slat clip. The engagement between these supports and the slat clips can be easily released by sliding the slat clips in the left and right direction by placing your hand on the handle, and by removing the slat clips from the supports in this way, the slat clips can be easily disengaged. The slat can then be removed from the operating body. As a result, even in an emergency when it is impossible to open or close the electric blind shutter due to a power outage, it is possible to easily create an escape opening by removing a few slats. This will ensure safety.
Furthermore, since the structure is simple and does not require any complicated special mechanisms as in the past, it is possible to significantly reduce costs.
